| 1 | 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 |
| 2 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018,63,23: | 54 |
| 3 | Risk factors for cervical lymph node metastasis in papillary thyroid microcarcinoma: a study of 1,587 patients显示文摘Objective: The purposes of this study were to identify risk factors for cervical lymph node metastasis and to examine the association between BRAF^(V600E) status and clinical features in papillary thyroid microcarcinoma(PTMC).Methods: A total of 1,587 patients with PTMC, treated in Tianjin Medical University Cancer Institute and Hospital from January2011 to March 2013, underwent retrospective analysis. We reviewed and analyzed factors including clinical results, pathology records, ultrasound results, and BRAF^(V600E) status.Results: Multivariate logistic regression analyses demonstrated that gender(male) [odds ratio(OR) = 1.845, P = 0.000], age(< 45 years)(OR = 1.606, P = 0.000), tumor size(> 6 mm)(OR = 2.137, P = 0.000), bilateralism(OR = 2.011, P = 0.000) and extrathyroidal extension(OR = 1.555, P = 0.001) served as independent predictors of central lymph node metastasis(CLNM).Moreover, CLNM(OR = 29.354, P = 0.000) served as an independent predictor of lateral lymph node metastasis(LLNM). Among patients with a solitary primary tumor, those with tumor location in the lower third of the thyroid lobe or the isthmus were more likely to experience CLNM(P < 0.05). Univariate analyses indicated that CLNM, LLNM, extrathyroidal extension, and multifocality were not significantly associated with BRAF^(V600E) mutation.Conclusions: The present study suggested that prophylactic neck dissection of the central compartment should be considered in patients with PTMC, particularly in men with tumor size greater than 6 mm, age less than 45 years, extrathyroidal extension, and tumor bilaterality. Among patients with PTMC, BRAF^(V600E) mutation is not significantly associated with prognostic factors. For a better understanding of surgical management of PTMC and the risk factors, we recommend multicenter research and long-term follow-up. | Xiangqian Zheng Chen Peng Ming Gao Jingtai Zhi Xiukun Hou Jingzhu Zhao Xi Wei Jiadong Chi Dapeng Li Biyun Qian | 2019 | Cancer Biology & Medicine2019,16,1: | 54 |
| 4 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021,41,11: | 29 |
| 5 | Rapid quantification of semen hepatitis B virus DNA by real-time polymerase chain reaction显示文摘AIM: To examine the sensitivity and accuracy of real-time polymerase chain reaction (PCR) for the quantification of hepatitis B virus (HBV) DNA in semen.METHODS: Hepatitis B viral DNA was isolated from HBV carriers' semen and sera using phenol extraction method and QTAamp DNA blood mini kit (Qiagen, Germany). HBV DNA was detected by conventional PCR and quantified by TaqMan technology-based real-time PCR (quantitative polymerase chain reaction (qPCR)). The detection threshold was 200 copies of HBV DNA for conventional PCR and 10 copies of HBV DNA for real time PCR per reaction.RESULTS: Both methods of phenol extraction and QIAamp DNA blood mini kit were suitable for isolating HBV DNA from semen. The value of the detection thresholds was 500 copies of HBV DNA per mL in the semen. The viral loads were 7.5×107 and 1.67×107 copies of HBV DNA per mL in two HBV infected patients' sera, while 2.L4×105 and 3.02×105 copies of HBV DNA per mL in the semen.CONCLUSION: Real-time PCR is a more sensitive and accurate method to detect and quantify HBV DNA in the semen. | Wei-Ping Qian Yue-Qiu Tan Ying Chen Ying Peng Zhi Li Guang-Xiu Lu Made C.

| 6 | Cap-assisted endoscopic sclerotherapy for hemorrhoids: Methods, feasibility and efficacy显示文摘AIM: To evaluate the methodology, feasibility, safety and efficacy of a novel method called cap-assisted endoscopic sclerotherapy(CAES) for internal hemorrhoids.METHODS: A pilot study on CAES for grade Ⅰ to Ⅲ internal hemorrhoids was performed. Colon and terminal ileum examination by colonoscopy was performed for all patients before starting CAES. Polypectomy and excision of anal papilla fibroma were performed if polyps or anal papilla fibroma were found and assessed to be suitable for resection under endoscopy. CAES was performed based on the requirement of the cap, endoscope, disposable endoscopic long injection needle, enough insufflated air and sclerosing agent.RESULTS: A total of 30 patients with grade Ⅰ to Ⅲ internal hemorrhoids was included. The follow-up was more than four weeks. No bleeding was observed after CAES. One(3.33%) patient claimed mild tenesmus within four days after CAES in that an endoscopist performed this procedure for the first time. One hundred percent of patients were satisfied with this novel procedure, especially for those patients who underwent CAES in conjunction with polypectomy or excision of anal papilla fibroma.CONCLUSION: CAES as a novel endoscopic sclerotherapy should be a convenient, safe and effective flexible endoscopic therapy for internal hemorrhoids. | Ting Zhang Li-Juan Xu Jie Xiang Zhi He Zhao-Yuan Peng Guang-Ming Huang Guo-Zhong Ji Fa-Ming Zhang | 2015 | World Journal of Gastrointestinal Endoscopy2015,7,19: | 22 |
| 7 | Detection of hepatitis C virus NS5 protein and genome in Chinese carcinoma of the extrahepatic bile duct and its significance显示文摘AIM To investigate the hepatitis C virus(HCV)infection in the tissues of carcinoma ofextrahepatic bile duct and study theircorrelation.METHODS HCV NS5 protein and HCV RNA weredetected by labeled streptavidin biotin(LSAB)method and in situ reverse transcriptionpolymerase chain reaction(IS-RT-PCR)insections of 51 cases of carcinoma ofextrahepatic bile duct and 34 cases of controlgroup(without malignant biliary disease).RESULTS In 51 cases of carcinoma ofextrahepatic bile duct,HCV NS5 protein wasdetected in 14(27.5%),which was clearlystained in the cytoplasm of cancer cell but not inthe nucleus or cell membrane.HCV RNA wasdetected in 18(35.4%),which was located inthe nucleus of cancer cell in 12 cases and in thecytoplasm in 6 cases.HCV NS5 protein and RNAcoexistence was found in 2 cases.In 34 cases ofcontrol group,HCV RNA was detected in 2(5.9%).HCV NS5 protein and RNA positive cellswere found either scattered or in clusters.CONCLUSION The prevalence of hepatitis C viral infection in the tissues of carcinoma ofextrahepatic bile duct was significantly higherthan in control group(X^2=9.808,P=0.002).The findings suggest a correlation between HCVinfection and carcinoma of extrahepatic bileduct,which is different from the traditionalviewpoint.HCV infection might be involved inthe development of carcinoma of extrahepaticbile duct. | Ming Yi Chen Zhi Qiang Huang Le Zhen Chen Ya Bing Gao Rui Yun Peng De Wen Wang | 2000 | World Journal of Gastroenterology2000,6,6: | 19 |
| 8 | A Chromosome-Scale Genome Assembly of Paper Mulberry(Bmussonetia papyrifera)Provides New Insights into Its Forage and Papermaking Usage显示文摘Paper mulberry(Broussonetia papyrifera)is a well-known woody tree historically used for Cai Lun papermaking,one of the four great inventions of ancient China.More recently,Paper mulberry has also been used as forage to address the shortage of feedstuff because of its digestible crude fiber and high protein contents.In this study,we obtained a chromosome-scale genome assembly for Paper mulberry using integrated approaches,including Illumina and PacBio sequencing platform as well as Hi-C,optical,and genetic maps.The assembled Paper mulberry genome consists of 386.83 Mb,which is close to the estimated size,and 99.25%(383.93 Mb)of the assembly was assigned to 13 pseudochromosomes.Comparative genomic analysis revealed the expansion and contraction in the flavonoid and lignin biosynthetic gene families,respectively,accounting for the enhanced flavonoid and decreased lignin biosynthesis in Paper mulberry.Moreover,the increased ratio of syringyl-lignin to guaiacyl-lignin in Paper mulberry underscores its suitability for use in medicine,forage,papermaking,and barkcloth making.We also identified the rootassociated microbiota of Paper mulberry and found that Pseudomonas and Rhizobia were enriched in its roots and may provide the source of nitrogen for its stems and leaves via symbiotic nitrogen fixation.Collectively,these results suggest that Paper mulberry might have undergone adaptive evolution and recruited nitrogen-fixing microbes to promote growth by enhancing flavonoid production and altering lignin monomer composition.Our study provides significant insights into genetic basis of the usefulness of Paper mulberry in papermaking and barkcloth making,and as forage.These insights will facilitate further domestication and selection as well as industrial utilization of Paper mulberry worldwide. | Xianjun Peng Hui Liu Peilin Chen Feng Tang Yanmin Hu Fenfen Wang Zhi Pi Meiling Zhao Naizhi Chen Hui Chen Xiaokang Zhang Xueqing Yan Min Liu Xiaojun Fu Guofeng Zhao Pu Yao Lili Wang He Dai Xuming Li Wei Xiong Wencai Xu Hongkun Zheng Haiyan Yu Shihua Shen | 2019 | Molecular Plant2019,12,5: | 18 |

| 11 | Genetic Analysis and Primary Mapping of pms4, a Photoperiod-Sensitive Genic Male Sterility Gene in Rice (Oryza sativa)显示文摘To understand the genetic characteristics of a new photoperiod-sensitive genic male sterile line Mian 9S, some reciprocal crosses were made between Mian 9S and six indica rice materials, Yangdao 6, Luhui 602, Shuihui 527, Mianhui 725, Fuhui 838 and Yixiang 1B. Genetic analysis results suggested that the photoperiod-sensitive genic male sterility (PGMS) of Mian 9S was controlled by a single recessive nuclear gene. Thus, the F2 population derived from the cross of Yangdao 6/Mian 9S was used to map the PGMS gene in Mian 9S. By using SSR markers, the PGMS gene of Mian 9S was mapped on one side of the markers, RM6659 and RM1305, on rice chromosome 4, with the genetic distances of 3.0 cM and 3.5 cM, respectively. The gene was a novel PGMS gene and designated tentatively as pms4. In addition, the application of the pms4 gene was discussed. | HUANG Ting-you WANG Zhi HU Yun-gao SHI Shou-pei PENG Tao CHU Xu-dong SHI Jun XIANG Zu-fen LIU Ding-you | 2008 | Rice science2008,15,2: | 13 |
| 12 | C-reactive Protein Level,Apolipoprotein B-to-apolipoprotein A-1 Ratio,and Risks of Ischemic Stroke and Coronary Heart Disease among Inner Mongolians in China显示文摘Objective We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1(ApoB/ApoA-1) ratio on the incidence of ischemic stroke(IS) or coronary heart disease(CHD) in a Mongolian population in China.Methods From June 2003 to July 2012,2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation.All the participants were divided into four subgroups according to C-reactive protein(CRP) level and ApoB/ApoA-1 ratio.Cox proportional hazard models were used to estimate the hazard ratios(HRs) and 95% confidence intervals(CIs) for the IS and CHD events in all the subgroups.Results The HRs(95% CI) for IS and CHD were 1.33(0.84-2.12),1.14(0.69-1.88),and 1.91(1.17-3.11) in the ‘low CRP level with high ApoB/ApoA-1',‘high CRP level with low ApoB/ApoA-1',and ‘high CRP level with high ApoB/ApoA-1' subgroups,respectively,in comparison with the ‘low CRP level with low ApoB/ApoA-1' subgroup.The risks of IS and CHD events was highest in the ‘high CRP level with high ApoB/ApoA-1' subgroup,with statistical significance.Conclusion High CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population.This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population. | TIAN Yun Fan ZHOU Yi Peng ZHONG Chong Ke BUREN Batu XU Tian LI Hong Mei ZHANG Ming Zhi WANG Ai Li ZHANG Yong Hong | 2016 | Biomedical and Environmental Sciences2016,29,7: | 12 |

| 14 | Effects of intermittent negative pressure on osteogenesis in human bone marrow-derived stroma cells显示文摘Objective:We investigated the effects of intermittent negative pressure on osteogenesis in human bone marrowderived stroma cells(BMSCs) in vitro. Methods:BMSCs were isolated from adult marrow donated by a hip osteoarthritis patient with prosthetic replacement and cultured in vitro. The third passage cells were divided into negative pressure treatment group and control group. The treatment group was induced by negative pressure intermittently(pressure:50 kPa,30 min/times,and twice daily). The control was cultured in conventional condition. The osteogenesis of BMSCs was examined by phase-contrast microscopy,the determination of alkaline phosphatase(ALP) activities,and the immunohistochemistry of collagen type I. The mRNA expressions of osteoprotegerin(OPG) and osteoprotegerin ligand(OPGL) in BMSCs were analyzed by real-time polymerase chain reaction(PCR). Results:BMSCs showed a typical appearance of osteoblast after 2 weeks of induction by intermittent negative pressure,the activity of ALP increased significantly,and the expression of collagen type I was positive. In the treatment group,the mRNA expression of OPG increased significantly(P<0.05) and the mRNA expression of OPGL decreased significantly(P<0.05) after 2 weeks,compared with the control. Conclusion:Intermittent negative pressure could promote osteogenesis in human BMSCs in vitro. | Zhi YANG Miao LIU Yin-gang ZHANG Xiong GUO Peng XU | 2009 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2009,10,3: | 12 |

| 16 | Immune checkpoint inhibitors for treatment of advanced gastric or gastroesophageal junction cancer:Current evidence and future perspectives显示文摘Despite the application of conventional therapies,the prognosis of advanced gastric cancer(GC)or gastroesophageal junction cancer(GEJC)is still poor.In recent years,immune checkpoint inhibitors(ICIs)have reshaped the paradigm of cancer therapy.Emerging evidence support the feasibility of programmed cell death-1(PD-1)and its ligand(PD-L1)inhibition in chemo-refractory GC/GEJC.Nivolumab and pembrolizumab have initially been approved in Japan and United States,respectively for the third-line treatment of progressive GC or GEJC.In March 2020,nivolumab has also been licensed in China for treating advanced GC/GEJC who received≥2 lines of systemic therapies.Current studies are moving forward to the first-line application or focusing on combination strategies,though data are insufficient and disputable.In this review,we summarize the recently reported and ongoing clinical trials in ICIs for advanced GC/GEJC.Molecular characteristics and clinical implications of different tumor subtypes are also reviewed.We further discuss the safety profile and biomarkers for predicting the response of ICIs,which has guiding values in clinical practice. | Zhening Zhang T ong Xie Xiaotian Zhang Changsong Qi Lin Shen Zhi Peng | 2020 | Chinese Journal of Cancer Research2020,32,3: | 10 |
| 17 | Effect of liniment levamisole on cellular immune functions of patients with chronic hepatitis B显示文摘AIM: To explore the effects of liniment levamisole on cellular immune functions of patients with chronic hepatitis B. METHODS: The levels of T lymphocyte subsets and mlL-2R in peripheral blood mononuclear cells (PBMCs) were measured by biotin-streptavidin (BSA) technique in patients with chronic hepatitis B before and after the treatment with liniment levamisole. RESULTS: After one course of treatment with liniment levamisole, the levels of CD3+, CD4+, and the ratio of CD4+/CD8+ increased as compared to those before the treatment but the level of CD8+ decreased. The total expression level of mIL-2R in PBMCs increased before and after the treatment with liniment levamisole. CONCLUSION: Liniment levamisole may reinforce cellular immune functions of patients with chronic hepatitis B. | Ke-Xia Wang Li-Hua Zhang Jiang-Long Peng Yong Liang Xue-Feng Wang Hui Zhi Xiang-Xia Wang Huan-Xiong Geng | 2005 | World Journal of Gastroenterology2005,11,45: | 10 |
| 18 | Evaluation of Ultrasound-guided Genitofemoral Nerve Block Combined with Ilioinguinal/iliohypogastric Nerve Block during Inguinal Hernia Repair in the Elderly显示文摘To evaluate the anesthetic effect of ultrasound-guided(USG)ilioinguinal/iliohypogastric nerve(Ⅱ/IHN)block combined with genital branch of genitofemoral nerve(GFN)block in the elderly undergoing inguinal hernia repair,54 old patients(aged 60-96years,ASAⅠ-Ⅲ)with indirect hernia were enrolled and scheduled for unilateral tensiofree herniorrhaphy.Patients were grouped randomly to receive either USGⅡ/IHN plus GFN block(Group G)or USGⅡ/IHN block alone(GroupⅠ).The intraoperative visual analogue scale(VAS)scores were recorded at skin incision,at spermatic cord/round ligament traction and at sac ligation.The resting and dynamic VAS scores were recorded postoperatively.The requirements of extra sedatives and analgesics for intra-and postoperative analgesia were assessed.Occurrence of complications of the block,postoperative nausea and vomiting and femoral nerve palsy was also reported.Both groups showed similar sensory block.When stretching spermatic cord/round ligament,the patients in group G had significantly lower VAS scores than in group.And group G used much fewer adjuvant sedatives and analgesics to achieve adequate anaesthesia.In addition,group G was presented with better intraoperative anaesthesia and lower postoperative dynamic VAS scores at all time points tested.No significant difference was found in the postoperative requirement of rescue medication.Both groups showed no complications related to the block and group G reported no femoral nerve palsy.The addition of GFN block toⅡ/IHN block improves the quality of perioperative anesthesia and analgesia in the elderly and reduces the consumption of extra sedatives and analgesics during the surgery. | Zhi HUANG Wei XIA Xiao-hong PENG Jin-yuan KE Wei WANG | 2019 | Current Medical Science2019,39,5: | 10 |
