| 2 | Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis. | Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao | 2000 | World Journal of Gastroenterology2000，6，6： | 52 |

| 4 | Relationship of hepatitis B virus infection of placental barrier and hepatitis B virus intra-uterine transmission mechanism显示文摘AIM: To explore the mechanism of intra-uterine transmission,the HBV infection status of placental tissue and in vitro cultured placental trophoblastic cells was tested through in vivo and in vitro experiments. METHODS: A variety of methods,such as ELISA,RT- PCR,IHC staining and immunofluorescent staining were employed to test the HBV marker positive pregnant women's placenta and in vitro cultured placental trophoblastic cells. RESULTS: The HBV DNA levels in pregnant women's serum and fetal cord blood were correlated. For those cord blood samples positive for HBV DNA,their maternal blood levels of HBV DNA were at a high level. The HBsAg IHC staining positive cells could be seen in the placental tissues and the presence of HBV DNA detected. After co-incubating the trophoblastic cells and HBV DNA positive serum in vitro,the expressions of both HBsAg and HBV DNA could be detected. CONCLUSION: The mechanism of HBV intra-uterine infection may be due to that HBV breaches the placental barrier and infects the fetus. | Han Bai Lin Zhang Li Ma Xiao-Guang Dou Guo-He Feng Gui-Zhen Zhao | 2007 | World Journal of Gastroenterology2007，13，26： | 30 |
| 5 | TIPS improves liver transplantation-free survival in cirrhotic patients with refractory ascites:An updated meta-analysis显示文摘AIM:To compare the liver transplantation-free(LTF)survival rates between patients who underwent transjugular intrahepatic portosystemic shunts(TIPS)and those who underwent paracentesis by an updated meta-analysis that pools the effects of both number of deaths and time to death.METHODS:MEDLINE,EMBASE,and the Cochrane Library were searched from the inception to October2012.LTF survival,liver transplantation,liver diseaserelated death,non-liver disease-related death,recurrent ascites,hepatic encephalopathy(HE)and severe HE,and hepatorenal syndrome were assessed as outcomes.LTF survival was estimated using a HR with a95%CI.Other outcomes were estimated using OR with95%CIs.Sensitivity analyses were performed to assess the effects of potential outliers in the studies according to the risk of bias and the study characteristics.RESULTS:Six randomized controlled trials with 390patients were included.In comparison to paracentesis,TIPS significantly improved LTF survival(HR=0.61,95%CI:0.46-0.82,P<0.001).TIPS also significantly decreased liver disease-related death(OR=0.62,95%CI:0.39-0.98,P=0.04),recurrent ascites(OR=0.15,95%CI:0.09-0.24,P<0.001)and hepatorenal syndrome(OR=0.32,95%CI:0.12-0.86,P=0.02).However,TIPS increased the risk of HE(OR=2.95,95%CI:1.87-4.66,P=0.02)and severe HE(OR=2.18,95%CI:1.27-3.76,P=0.005).CONCLUSION:TIPS significantly improved the LTF survival of cirrhotic patients with refractory ascites and decreased the risk of recurrent ascites and hepatorenal syndrome with the cost of increased risk of HE compared with paracentesis.Further studies are warranted to validate the survival benefit of TIPS in clinical practice settings. | Ming Bai Xing-Shun Qi Zhi-Ping Yang Man Yang Dai-Ming Fan Guo-Hong Han | 2014 | World Journal of Gastroenterology2014，20，10： | 29 |
| 6 | Role of moxibustion in inflammatory responses during treatment of rat ulcerative colitis显示文摘AIM: To investigate the efficacy of moxibustion in ulcerative colitis(UC) rats from morphological, immunological and molecular biological perspectives.METHODS: Thirty-two Sprague-Dawley rats were randomly assigned to a blank control group(normal rats, n = 6) and a model replication(MR) group(UC rats, n = 26). A UC model was established by 2,4,6-trinitrobenzenesulfonic acid/dextran sulfate sodium enema. Rats in the MR group were further randomly assigned to a 9-min moxibustion(9M) group(9 moxa-cone, n = 6), 6-min moxibustion(6M) group(6 moxa-cone, n = 6), 3-min moxibustion(3M) group(3 moxa-cone, n = 6), and a waiting list control(WLC) group(no moxibustion treatment, n = 6). Rats in the moxibustion treatment group were treated in 14 sessions over 28 d. Disease activity, local tissue morphology, serum level of interleukin(IL)-8 and IL-10, and expression of Toll-like receptor(TLR)9 aswell as nuclear factor(NF)-κB p65 in colonic tissue were determined by disease activity index(DAI), hematoxylin and eosin staining, electron microscopy, enzyme-linked immunosorbent assay and Western blotting, respectively.RESULTS: DAI was lowest in the 9M group and highest in the WLC group. The differences in DAI between the moxibustion treatment(3M, 6M, 9M) and no treatment groups were significant for all one-to-one comparisons(0.60 ± 0.54 vs 1.20 ± 0.44, 0.60 ± 0.54 vs 1.80 ± 0.45, 0.60 ± 0.54 vs 3.0 ± 0.45, respectively, P < 0.05). Light and electron microscopy showed that the neatness of the glandular arrangement in colonic mucosal epithelia gradually increased in the WLC, 3M, 6M to 9M groups. IL-8 level successively decreased while IL-10 level increased from the WLC to 3M, 6M and 9M groups. The differences among these groups were significant for all comparisons(105.46 ± 8.75 vs 76.61 ± 3.58, 105.46 ± 8.75 vs 69.78 ± 1.87, 105.46 ± 8.75 vs 67.41 ± 1.84, respectively, P < 0.01 for IL-8; and 30.83 ± 1.29 vs 75.64 ± 1.90, 30.83 ± 1.29 vs 80.90 ± 3.16, 30.83 ± 1.29 vs 83.46 ± 2.37, respectively, P < 0.01 for IL-10), except comparison of 6M vs 9M. Expression of TLR9 and NF-κB p65 decreased in order: highest in the WLC group and lowest in the 9M group. In addition, the differences among the WLC, 3M, 6M and 9M groups were significant for all comparisons(0.492 ± 0.026 vs 0.380 ± 0.022, 0.492 ± 0.026 vs 0.355 ± 0.005, 0.492 ± 0.026 vs 0.327 ± 0.015, respectively, P < 0.05 for TLR9; and 0.436 ± 0.041 vs 0.326 ± 0.022, 0.436 ± 0.041 vs 0.293 ± 0.006, 0.436 ± 0.041 vs 0.265 ± 0.017, respectively, P < 0.05 for NF-κB p65).CONCLUSION: Moxibustion repairs damaged colonic mucosa, suppresses serum IL-8, activates serum IL-10 level, and decreases expression of TLR-9 and NF-κB p65 in UC rats. | Yang Han Tie-Ming Ma Mao-Lin Lu Lu Ren Xian-De Ma Zeng-Hua Bai | 2014 | World Journal of Gastroenterology2014，20，32： | 27 |
| 7 | Shunting branch of portal vein and stent position predict survival after transjugular intrahepatic portosystemic shunt显示文摘AIM:To evaluate the effect of the shunting branch of the portal vein(PV)(left or right)and the initial stent position(optimal or suboptimal)of a transjugular intrahepatic portosystemic shunt(TIPS).METHODS:We retrospectively reviewed 307 consecu5tive cirrhotic patients who underwent TIPS placement for variceal bleeding from March 2001 to July 2010 at our center.The left PV was used in 221 patients and the right PV in the remaining 86 patients.And,224 and83 patients have optimal stent position and sub-optimal stent positions,respectively.The patients were followed until October 2011 or their death.Hepatic encephalopathy,shunt dysfunction,and survival were evaluated as outcomes.The difference between the groups was compared by Kaplan-Meier analysis.A Cox regression model was employed to evaluate the predictors.RESULTS:Among the patients who underwent TIPS to the left PV,the risk of hepatic encephalopathy(P=0.002)and mortality were lower(P<0.001)compared to those to the right PV.Patients who underwent TIPS with optimal initial stent position had a higher primary patency(P<0.001)and better survival(P=0.006)than those with suboptimal initial stent position.The shunting branch of the portal vein and the initial stent position were independent predictors of hepatic encephalopathy and shunt dysfunction after TIPS,respectively.And,both were independent predictors of survival.CONCLUSION:TIPS placed to the left portal vein with optimal stent position may reduce the risk of hepatic encephalopathy and improve the primary patency rates,thereby prolonging survival. | Ming Bai Chuang-Ye He Xing-Shun Qi Zhan-Xin Yin Jian-Hong Wang Wen-Gang Guo Jing Niu Jie-Lai Xia Zhuo-Li Zhang Andrew C Larson Kai-Chun Wu Dai-Ming Fan Guo-Hong Han | 2014 | World Journal of Gastroenterology2014，20，3： | 26 |
| 8 | Differential expression of serum miR-126,miR-141 and miR-21 as novel biomarkers for early detection of liver metastasis in colorectal cancer显示文摘Objective:MicroRNAs(miRNAs) have potential as diagnostic biomarkers in cancer.Evaluation of the association between miRNA expression patterns and early detection of liver metastasis in colorectal cancer(CRC) has not been reported.Methods:We investigated the expression of metastasis-associated miRs-31,335,206,141,126,200b,200c,21,Let7a,Let7b and Let7c in localized,liver-metastatic and other organ-metastatic CRC(OM-CRC).Expressions of target miRNAs in serum were evaluated in 116 consecutive localized CRC(L-CRC),72 synchronous liver-metastatic CRC(SLM-CRC) and 36 other OM-CRC by quantitative real-time PCR.Results:Seven of 11 tested miRNAs could be detected from serum.Four miRNAs,miR-126,Let-7a,miR-141 and miR-21 were identified as metastasis-associated miRNAs.Compared with L-CRC,significant upregulated expression was observed for miR-141 and miR-21 in SLM-CRC and OM-CRC,down-regulated expression was observed for miR-126 in SLM-CRC and OM-CRC,and up-regulated expression of Let-7a in OM-CRC.The receiver operating characteristic(ROC) curve showed serum miR-126 had a cut-off [log 10 relative quantity(log 10 RQ)=–0.2005] with 77.78% sensitivity and 68.97% specificity with an area under curve(AUC) of 0.7564,miR-141 had a cut-off(log 10 RQ=–0.2285) with 86.11% sensitivity and 76.11% specificity with an AUC of 0.8279,and miR-21 had a cut-off(log 10 RQ=–0.1310) with 73.61% sensitivity and 66.38% specificity with an AUC of 0.7479.Conclusions:We identified liver metastasis-associated miRNAs,suggesting serum miR-126,miR-141 and miR-21 may be novel biomarkers for clinical diagnosis of early stage liver-metastatic CRC. | Jie Yin Zhigang Bai Jianning Song Yun Yang Jin Wang Wei Han Jun Zhang Hua Meng Xuemei Ma Yao Yang Tingting Wang Weirong Li Zhongtao Zhang | 2014 | Chinese Journal of Cancer Research2014，26，1： | 22 |
| 9 | T cell–associated immunoregulation and antiviral effect of oxymatrine in hydrodynamic injection HBV mouse model显示文摘Although oxymatrine(OMT) has been shown to directly inhibit the replication of hepatitis B virus(HBV) in vitro, limited research has been done with this drug in vivo. In the present study, the antiviral effect of OMT was investigated in an immunocompetent mouse model of chronic HBV infection.The infection was achieved by tail vein injection of a large volume of DNA solution. OMT(2.2, 6.7 and20 mg/kg) was administered by daily intraperitoneal injection for 6 weeks. The efficacy of OMT was evaluated by the levels of HBV DNA, hepatitis B surface antigen(HBs Ag), hepatitis B e antigen(HBe Ag)and hepatitis B core antigen(HBc Ag). The immunoregulatory activity of OMT was evaluated by serum ELISA and flow cytometry. Results shows that OMT at 20 mg/kg inhibited HBV replication, and it was more efficient than entecavir(ETV) in the elimination of serum HBs Ag and intrahepatic HBc Ag. Inaddition, OMT accelerated the production of interferon-γ(IFN-γ) in a dose-dependent manner in CD4^+T cells. Our findings demonstrate the beneficial effects of OMT on the enhancement of immunological function and in the control of HBV antigens. The findings suggest this drug to be a good antiviral therapeutic candidate for the treatment of HBV infection. | Xiuxiu Sang Ruilin Wang Yanzhong Han Cong’en Zhang Honghui Shen Zhirui Yang Yin Xiong Huimin Liu Shijing Liu Ruisheng Li Ruichuang Yang Jiabo Wang Xuejun Wang Zhaofang Bai Xiaohe Xiao | 2017 | Acta Pharmaceutica Sinica B2017，7，3： | 20 |
| 10 | Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management. | Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng | 2015 | Chinese Birds2015，，3： | 20 |

| 12 | Characteristics of atmospheric single particles during haze periods in a typical urban area of Beijing:A case study in October,2014显示文摘To investigate the composition and possible sources of particles, especially during heavy haze pollution, a single particle aerosol mass spectrometer(SPAMS) was deployed to measure the changes of single particle species and sizes during October of 2014, in Beijing. A total of 2,871,431 particles with both positive and negative spectra were collected and characterized in combination with the adaptive resonance theory neural network algorithm(ART-2a). Eight types of particles were classified: dust particles(dust, 8.1%), elemental carbon(EC, 29.0%), organic carbon(OC, 18.0%), EC and OC combined particles(ECOC, 9.5%),Na-K containing particles(Na K, 7.9%), K-containing particles(K, 21.8%), organic nitrogen and potassium containing particles(KCN, 2.3%), and metal-containing particles(metal,3.6%). Three haze pollution events(P1, P2, P3) and one clean period(clean) were analyzed,based on the mass and number concentration of PM_(2.5)and the back trajectory results from the hybrid single particle Lagrangian integrated trajectory model(Hysplit-4 model). Results showed that EC, OC and K were the major components of single particles during the three haze pollution periods, which showed clearly increased ratios compared with those in the clean period. Results from the mixing state of secondary species of different types of particles showed that sulfate and nitrate were more readily mixed with carbon-containing particles during haze pollution episodes than in clean periods. | Lang Liu Yanli Wang Shiyong Du Wenjie Zhang Lujian Hou Sverre Vedal Bin Han Wen Yang Mindong Chen Zhipeng Bai | 2016 | Journal of Environmental Sciences2016，28，2： | 19 |

| 14 | Changes with aging in gastric biomarkers levels and in biochemical factors associated with Helicobacter pylori infection in asymptomatic Chinese population显示文摘AIM To observe changes in gastric biomarker levels with age and effects of Helicobacter pylori(H. pylori) infection in a healthy population, and explore factors associated with gastric biomarkers.METHODS Three hundred and ninety-five subjects were selected and underwent physical examinations, biochemical tests, and measurement of serum pepsinogen(PG)Ⅰ and Ⅱ, gastrin-17(G-17) and H. pylori antibody levels. Analyses were made by Student's t-test, ANOVA, Pearson's correlation and multiple linear regressions.RESULTS PGII levels were higher in the ≥ 65-years-old age group(P < 0.05) and PGI/PGII were lower in the ≥ 75-years-old age group(P = 0.035) compared to the 35-44-years-old age group. Levels of low-density lipoprotein cholesterol(LDL-C) were higher(P = 0.009) in H. pylori-infected subjects that were male. LDL-C levels were higher in 55-74-years-old age group(P < 0.05) for H. pylori-infected subjects and 45-64-yearsold age group(P < 0.05) for non-infected subjects compared to 35-44-years-old age group. Hp-Ig G level positively correlated with PGⅠ, PGⅡ and G-17(P < 0.001, P < 0.001, P = 0.006), and negatively correlated with PGI/PGII(P < 0.001). Creatinine positively correlated with PGⅠ, PGⅡ and G-17(P < 0.001, P < 0.001, P < 0.001). Fasting blood glucose(FBG) positively correlated with PGⅠ/PGⅡ and G-17(P < 0.001, P = 0.037). Age positively correlated with PGII and G-17(P = 0.005, P = 0.026).CONCLUSION PGII levels increased while PGI/PGII declined with age in a healthy population. H. pylori infection had an effect on raising LDL-C levels to increase the risk of atherosclerosis in males, especially those of elderly age. Age, H. pylori infection, levels of renal function and FBG were associated with levels of pepsinogens and gastrin. | Jin-Hua Shan Xiao-Juan Bai Lu-Lu Han Yuan Yuan Xue-Feng Sun | 2017 | World Journal of Gastroenterology2017，23，32： | 18 |
| 15 | Single-cell transcriptomic analysis defines the interplay between tumor cells,viral infection,and the microenvironment in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an Epstein-Barr virus(EBV)-associated malignancy with a complex tumor ecosystem.How the interplay between tumor cells,EBV,and the microenvironment contributes to NPC progression and immune evasion remains unclear.Here we performed single-cell RNA sequencing on^104,000 cells from 19 EBV^+NPCs and 7 nonmalignant nasopharyngeal biopsies,simultaneously profiling the transcriptomes of malignant cells,EBV,stromal and immune cells.Overall,we identified global upregulation of interferon responses in the multicellular ecosystem of NPC.Notably,an epithelial–immune dual feature of malignant cells was discovered and associated with poor prognosis.Functional experiments revealed that tumor cells with this dual feature exhibited a higher capacity for tumorigenesis.Further characterization of the cellular components of the tumor microenvironment(TME)and their interactions with tumor cells revealed that the dual feature of tumor cells was positively correlated with the expression of co-inhibitory receptors on CD8^+tumor-infiltrating T cells.In addition,tumor cells with the dual feature were found to repress IFN-γproduction by T cells,demonstrating their capacity for immune suppression.Our results provide new insights into the multicellular ecosystem of NPC and offer important clinical implications. | Shanzhao Jin Ruoyan Li Ming-Yuan Chen Chao Yu Lin-Quan Tang Yan-Min Liu Jiang-Ping Li Yi-Na Liu Yi-Ling Luo Yifan Zhao Yu Zhang Tian-Liang Xia Shang-Xin Liu Qi Liu Guan-Nan Wang Rui You Jing-Yun Peng Jiang Li Feng Han Jianwei Wang Qiu-Yan Chen Li Zhang Hai-Qiang Mai Benjamin E.Gewurz Bo Zhao Lawrence S.Young Qian Zhong Fan Bai Mu-Sheng Zeng | 2020 | Cell Research2020，30，11： | 16 |

METHODS: A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS: Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old(ranged from 3 to 63 years old). The 110 patients(74.32%) were male and 127 patients(85.81%) were adults(≥18 years old). The old upper, lower, and bicanalicular lacerations were found in 5(3.38%), 39(26.35%), and 104 patients(70.27%), respectively. The mechanism of old injury was primarily due to motor vehicle accidents(n=53, 35.81%). The mean time from injury to repair was 43.61mo(ranged from 1 to 360mo). Associated old ocular and orbit injuries were found in 65 patients(43.92%), and chronic dacryocystitis in 18 patients(12.16%). The main cause of delayed repair was that doctors or patients didn't pay attention to the canalicular laceration because of the concurrent severe injuries(n=71, 47.97%). Totally 136 patients(91.89%) with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients(13.51%) were combined with dacryocystorhinostomy. In these cases, 132 patients(97.06%) attained anatomic success, 121 patients(88.97%) reported no epiphora(functional success), 11 patients(8.09%) reported significant epiphora anesis(functional improvement), and 4(2.94%) reported no significant anesis(functional failure). Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair.CONCLUSION: The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration. | Fang Bai Hai Tao Yan Zhang Peng Wang Cui Han Yi-Fei Huang Ye Tao | 2017 | International Journal of Ophthalmology(English edition)2017，10，6： | 15 |
| 18 | Human placenta-derived mesenchymal stem cells loaded on linear ordered collagen scaffold improves functional recovery after completely transected spinal cord injury in canine显示文摘Traumatic spinal cord injury(SCI) is a major challenge in the clinic. In this study, we sought to examine the synergistic effects of linear ordered collagen scaffold(LOCS) and human placenta-derived mesenchymal stem cells(hPMSCs) when transplanted into completely transected beagle dogs. After 36 weeks observation, we found that LOCS+hPMSCs implants promoted better hindlimb locomotor recovery than was observed in the non-treatment(control) group and LOCS group. Histological analysis showed that the regenerated tissue after treatment was well integrated with the host tissue, and dramatically reduced the volume of cystic and chondroitin sulfate proteoglycans(CSPGs) expression. Furthermore, the LOCS+hPMSCs group also showed more neuron-specific βIII-tubulin(Tuj-1)-and NeuN-positive neurons in the lesion area, as well as axonal regeneration, remyelination and synapse formation in the lesion site. Additionally, dogs in the LOCS+hPMSCs group experienced enhanced sprouting of both ascending(CGRP-positive) sensory fibers and descending(5-HT-and TH-positive) motor fibers at the lesion area. All these data together suggested that the combined treatment had beneficial effects on neuronal regeneration and functional improvement in a canine complete transection model. Therefore, LOCS+hPMSCs implantation holds a great promise for bridging the nerve defect and may be clinically useful in the near future. | Sufang Han Zhifeng Xiao Xing Li Huan Zhao Bin Wang Zhixue Qiu Zhi Li Xin Mei Bai Xu Caixia Fan Bing Chen Jin Han Yanzheng Gu Huilin Yang Qin Shi Jianwu Dai | 2018 | Science China(Life Sciences)2018，61，1： | 15 |
| 19 | One-stitch anastomosis through the skin with bicanalicular intubation:a modified approach for repair of bicanalicular laceration显示文摘AIM:To evaluate the efficacy and safety of one-stitch anastomosis through the skin with bicanalicular silicone tube intubation in repairing of bicanalicular laceration.METHODS:The clinical data of 15 consecutive patients with both superior and inferior canalicular laceration in one eye who underwent surgical repair using one-stitch anastomosis through the skin and bicanalicular stent were retrospective studied.All the operations were performed under surgical microscope,5-0 silk sutures were used and were with bicanalicular silicone tube(diameter was 8mm) intubation,for one lacerated canaliculi one-stitch anastomosis through the skin.The stents were left in place for 3 months postoperatively and then removed.The follow-up period was 3-36 months(average 14 months). RESULTS:In 15 patients,13 patients were cured entirely,1 patient was meliorated,1 patient with no effects.All patients had got good recovery of eyelid laceration with no traumatic deformity in eyelid and canthus.Complication was seen in one case,for not followed the doctor's guidance to come back to hospital to had the suture removed on the 7thday after operation,when he came at the 15thday,the inferior canalicular wall and eyelid skin were corroded by the suture caused 2mm wound,and the inside silicone tube was exposed,a promptly repair with 10-0 nylon suture was done,the wound healed in a week.There were no early tube protrusions and punctal slits in the patients.CONCLUSION:One-stitch anastomosis through the skin with bicanalicular silicone tube intubation is a good method in repair of bicanalicular laceration in one eye,the cut ends can be anastomosed directly,and with excellent cosmetic results,it is acceptable for the patients.For there is no suture remained in the wound permanently,so there is no suture-related granuloma which may cause obstruction or stenosis of canaliculi.It is simple,economical,effective and safe. | Hai Tao Peng Wang Cui Han Jian Zhang Fang Bai Zhao-Yan He | 2013 | International Journal of Ophthalmology(English edition)2013，6，5： | 14 |
| 20 | Rationales for expression and altered expression of apoptotic protease activating factor-1 gene in gastric cancer显示文摘AIM: To elucidate the relationship between apoptotic protease activating factor-1 (Apaf-1) gene and gastric cancer. METHODS: Thirty-five postoperative cancer and adjacent normal tissue samples were collected in the present study. Expression of the Apaf-1 gene in these samples was analyzed by semi-quantitative RT-PCR. Loss of heterozygosity (LOH) was used to determine whether there was loss of Apaf-1 gene in domain of 12q22-23 in the samples. Promoter methylation of Apaf-1 gene in the samples was analyzed by methylation specific (MSP) PCR. RESULTS: The expression of Apaf-1 mRNA in gastric cancer tissue samples was 51%. The LOH frequency of D12S346, D12S1706, D12S327, D12S1657 and D12S393 was 33%, 8%, 58%, 12% and 42%, respectively. Fifty percent LOH was found at two sites and 17% LOH at three sites. Apaf-1 mRNA expression decreased significantly in 13 cases (rs = 0.487, P = 0.003). The rate of Apaf-1 promoter methylation was 49% in gastric cancer tissue samples and 23% in para-cancerous tissue samples. Promoter methylation occurred significantly in 16 of 18 gastric cancer tissue samples with decreased expression of Apaf-1 mRNA rs = 0.886, P = 10-6). CONCLUSION: The expression of Apaf-1 gene is low in gastric cancer tissues. Methylation of Apaf-1 gene promoter and LOH in domain of 12q22-23 are the main reasons for the expression and altered expression of Apaf-1 gene. | He-Ling Wang Han Bai Yan Li Jun Sun Xue-Qing wang | 2007 | World Journal of Gastroenterology2007，13，38： | 13 |
