1Wet Cupping Therapy Improves Local Blood Perfusion and Analgesic Effects in Patients with Nerve-Root Type Cervical Spondylosis显示文摘Objective: To observe wet cupping therapy(WCT) on local blood perfusion and analgesic effects in patients with nerve-root type cervical spondylosis(NT-CS). Methods: Fifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture(JA) group according a random number table. WCT group(30 cases) was treated with WCT for 10 min, and JA group(27 cases) was treated with acupuncture for 10 min. The treatment efficacies were evaluated with a Visual Analogue Scale(VAS). Blood perfusion at Dazhui(GV 14) and Jianjing(GB 21) acupoints(affected side) was observed with a laser speckle flowmetry, and its variations before and after treatment in both groups were compared as well. Results: In both groups, the VAS scores significantly decreased after the intervention(P<0.01), while the blood perfusion at the two acupoints significantly increased after intervention(P<0.05); however, the increasement magnitude caused by WCT was obvious compared with JA(P<0.05). Conclusion: WCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points.MENG Xiang-wen WANG Ying PIAO Sheng-ai LV Wen-tao ZHU Cheng-hui MU Ming-yuan LI Dan-dan LIU Hua-peng GUO Yi 2018Chinese Journal of Integrative Medicine2018,24,11:33

3Prediction of cervical lymph node metastases in papillary thyroid microcarcinoma by sonographic features of the primary site显示文摘Objective: To study the sonographic features of the primary site of papillary thyroid microcarcinoma(PTMC) for the prediction of cervical lymph node metastasis during preoperative diagnosis.Methods: A total of 710 PTMC patients between 2013 and 2016 with a diagnosis of cervical lymph node metastases were reviewed.We analyzed the sonographic features of the PTMC primary site to predict ipsilateral or central lymph node metastases in univariate and multivariate models.The ratio of abutment/perimeter of the PTMC primary site was utilized to evaluate cervical lymph node status.Results: Regarding clinical characteristics, multifocality and extrathyroidal extension were associated with cervical lymph node involvement.In the multivariate regression model, calcification and the abutment/perimeter ratio of lesions were evaluated as independent factors in level Ⅵ, ipsilateral or skip cervical lymph node metastases.The cut-off value of the ratio of abutment/perimeter of the PTMC primary site(25%) was significantly correlated with cervical lymph node metastases(P = 0.000).Conclusions: Independent sonographic features, including lesion size, lesion location, calcification, and the ratio of abutment/perimeter of the primary site, were associated with cervical lymph node metastases in PTMC patients.Xi Wei Meng Wang Xiaoqing Wang Xiangqian Zheng Ying Li Yi Pan Yueguo Li Jiali Mu Yang Yu Dapeng Li Ming Gao Sheng Zhang 2019Cancer Biology & Medicine2019,16,3:22
4An HBV-encoded miRNA activates innate immunity to restrict HBV replication显示文摘We previously identified that hepatitis B virus(HBV)encodes a microRNA(HBV-miR-3)that restrains HBV replication by targeting the HBV transcript.However,whether HBV-miR-3 affects host innate immunity to modulate HBV replication remains unclear.Here,we examined the vital functions of HBV-miR-3 in the innate immune response after HBV infection.We found that HBV-miR-3 expression gradually increased in a dose-and time-dependent manner in HBV-infected HepG2-NTCP cells.HBV-miR-3 activated the JAK/STAT signaling pathway by downregulating SOCS5 in hepatocytes,thereby enhancing the IFN-induced anti-HBV effect.In addition,HBVmiR-3 in exosomes facilitated the Ml polarization of macrophages.Furthermore,exosomes containing HBV-miR-3 enhanced the secretion of IL-6 via inhibiting the SOCS5-mediated ubiquitination of EGFR.In short,these results demonstrate that HBV-miR-3 activates the innate immune response to restrain HBV replication by multiple pathways,which may suppress HBV-induced acute liver cell injury and affect the progression of persistent HBV infection.Xiaoqing Zhao Lu Sun Ting Mu Jianying Yi Chaoqun Ma Hong Xie Min Liu Hua Tang 2020Journal of Molecular Cell Biology2020,12,4:17

6Urban garbage disposal and management in China显示文摘This paper, probing into the present situation of urban domestic garbage by analyzing its growing trend, compositional change and regional difference, reveals the problems existing in its disposal and management in China. Meanwhile, a questionnaire was conducted in five big cities around China for surveying urban residents’ attitudes towards garbage disposal and management policies and measures. Results showed the output of urban domestic garbage in Chinese cities is ever increasing, and the recoverable materials and energy in garbage composition are also increasing. The population growth, economic development, and increase of residents’ expenditure level are the main factors influencing the growing output and changing composition of the garbage. Information acquired from the questionnaire showed that majority of the urban residents are in favor of the garbage reduction policies and managerial measures and are willing to collaborate with municipal government in battling against garbage. Based on the analysis and questionnaire, some policymaking oriented suggestions such as operating the garbage disposal from a social welfare service to a sector of profit gaining enterprises, transferring the garbage management from passive end control to active source control, promoting the classified garbage collection in cities around China, and charging garbage fees for its cleanup and disposal, have also been put forward in the paper.JIANG Yuan, KANG Mu yi *, LIU Zheng, ZHOU Yan fang (Institute of Resources Science, Beijing Normal University, Beijing 100875, China. 2003Journal of Environmental Sciences2003,15,4:14

13Porcine acute liver failure model established by two-phase surgery and treated with hollow fiber bioartificial liver support system显示文摘AIM: To establish a highly reproducible animal model of acute liver failure (ALF), for assessing theeffect of bioartificial liver support system (BALSS).METHODS: A two-phase complete liver devascularization procedure was performed in eight loco-hybrid pigs. Blood biochemical index and liver biopsy were studied every 2 h after surgery, and survival time was recorded. The BALSS constructed with high volume recirculating technique was a hollow fiber circulating system consisting of a hepatocyte reactor-hollow fiber module inoculated with microcarrieradhering hepatocytes, and a double pump, heparinized,thermostabilized, micro-capsulized activated carbonadsorbing plasmapheresis system. Twelve pigs undergoing two-phase surgery were randomized into: control group (perfused without hepatocytes, n = 6) and treatment group (perfused with hepatocytes, n = 6). Intergroup liver biochemical indexes, survival time, and liver pathological changes were analyzed at regular intervals.RESULTS: Two-phase surgery was performed in all the experimental pigs, and there was no obvious difference between their biochemical indexes. After 3 h of phase Ⅱ surgery, ammonia (Amm) increased to (269±37) μmol/L.After 5 h of the surgery, fibrinogen (Fib) decreased to (1.5±0.2) g/L. After 7 h of the surgery, ALT, AST, Tbil and PT were (7.6±1.8) nka/L, (40±5) nka/L, (55±8) μmol/L and (17.5±1.7) nka/L respectively. After 9 h of surgery, ALB and Cr were (27±4) g/L and (87±9) μmol/L. After 13 h of surgery, BUN was (3.5±0.9) μmol/L. All the above values were different from those determined before surgery.Survival time of pigs averaged 13.5±1.4 h. ALF pigs in the other group were treated with BALSS. The comparison analysis between the treated and control animals showed the changes of Tbil, PT, Alb, BUN, Cr, Fib, and Amm (P<0.01), but there was no change of ALT and AST. The survival time was statistically different (P<0.01), and there was no significant difference in histological changes.CONCLUSION: The porcine ALF model established bytwo-phase devascularized surgery is valid and reproducible.The hollow fiber BALSS can meet the needs of life support and is effective in treating ALF.Yi Gao Ning Mu Xiao-Ping Xu Yan Wang 2005World Journal of Gastroenterology2005,11,35:8
14Intensive phototherapy vs.exchange transfusion for the treatment of neonatal hyperbilirubinemia:a multicenter retrospective cohort study显示文摘Background:Intensive phototherapy(IPT)and exchange transfusion(ET)are the main treatments for extreme hyperbilirubinemia.However,there is no reliable evidence on determining the thresholds for these treatments.This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia.Methods:This retrospective cohort study was conducted in seven centers from January 2015 to January 2018.Patients with extreme hyperbilirubinemia that met the criteria of ET were included.Patients were divided into three subgroups(low-,medium-,and high-risk)according to gestational week and risk factors.Propensity score matching(PSM)was performed to balance the data before treatment.Study outcomes included the development of bilirubin encephalopathy,duration of hospitalization,expenses,and complications.Mortality,auditory complications,seizures,enamel dysplasia,ocular motility disorders,athetosis,motor,and language development were evaluated during follow-up at age of 3 years.Results:A total of 1164 patients were included in this study.After PSM,296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-,medium-,and high-risk subgroups with 188,364,and 40 matched patients,respectively.No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity,complications,and sequelae.Hospitalization duration and expenses were lower in the low-and medium-risk subgroups in the IPT only group.Conclusions:In this study,our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia.The indication of ET for patients with hyperbilirubinemia could be stricter.However,it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors.If IPT can be guaranteed and proved to be therapeutic,ET should be avoided as much as possible.Meng Zhang Yang He Jun Tang Wenbin Dong Yong Zhang Benjin Zhang Hong Wan Quanmin Deng Lirong Guan Bin Xia Zhong Chen Min Ge Jing Zhao Wenxing Li Jingjun Pei Yi Qu Dezhi Mu 2022Chinese Medical Journal2022,,5:7
15The Relationship between Polymorphisms at 17 Gene Sites and Hypertension among the Aboriginal Tibetan People显示文摘Objective The incidence of hypertension in Tibet ranks highest among all Chinese provinces. This may be due to genetic changes caused by Tibet's unique natural environment and agrarian lifestyle, prompting us to investigated the relationship between gene polymorphisms and hypertension. Methods Blood samples were collected from 229 hypertensive participants and 372 healthy (control) participants from five Tibetan counties. Seventeen single nucleotide polymorphisms were investigated for their connection to hypertension. Results The C allele at rs2070744 of the NOS3 gene was shown to be significantly associated with hypertension (P=0.0443; OR=1.636). Additionally, the T allele of rs4961 of the ADD gene was correlated with hypertension in women (P=0.03124; OR=1.584). Conclusion In this study we found that the NOS3 and ADD genes were related to a high incidence of hypertension among Tibetans. NOS3 gene plays a role in regulating vascular tone and blood vessel diameter, which may be altered by the low-oxygen environment of Tibet. ADD is involved in water and salt metabolism, which is consistent with the high-salt diet of Tibetans. The correlations elucidated by our study were different from those of other ethnic groups, indicating that these findings may be specific to the Tibetan people.LI Kui LIANG Yu SUN Yin ZHANG Ling Xia YI Xin CHEN Yong GU SANG LA MU WANG Jian 2012Biomedical and Environmental Sciences2012,25,5:6
16The Spatial Color Mixing Model of Digital Camouflage Pattern显示文摘A spatial color-mixing model based on tricolor angular frequencies is proposed in consideration that the design theory falls behind the application of digital camouflage pattern.The model is based on Fourier transform and Gaussian low-pass filter(LPF).In the model,the tricolor angular frequencies are introduced to the spatial frequency response function of human color vision,and the effects of atmospheric attenuation and air screen brightness on color mixture are considered.The field test shows that the model can simulate the color-mixing process in the aspects of color-mixing order,and shape and position of color-mixing spot.But the color-mixing spot color is not perfect,which can be improved by optimizing the atmospheric parameters and tricolor cut-off angular frequencies.The model provides a tool for the research on digital camouflage pattern.Yong ZHANG Shi-qiang XUE Xiao-jun JIANG Jing-yang MU Yang YI 2013Defence Technology(防务技术)2013,9,3:6
17Comparison of Histological, Microbiological, and Molecular Methods in Diagnosis of Patients with TBLN Having Different Anti-TB Treatment Background显示文摘Objective The influence of anti-tuberculosis(TB) treatment history on tuberculous lymphadenitis(TBLN) diagnosis is unclear. Therefore, this study aims to evaluate the diagnostic methods, including histology, microbiology, and molecular tests, used for TBLN. Methods In this study, suspected patients with TBLN and having different anti-TB treatment background were enrolled. All the samples were tested simultaneously by histology, Ziehl-Neelsen(ZN) staining, mycobacterial culture(culture), Xpert MTB/RIF(xpert), real-time PCR, and high-resolution melting curve PCR(HRM). Thereafter, the performance of these methods on samples with different anti-TB treatment background was assessed. Results In our study, 89 patients were prospectively included 82 patients with TBLN and 7 with other diseases. The overall sensitivities of Xpert, real-time PCR, histology, ZN staining, and culture were 86.6%, 69.5%, 58.5%, 43.9%, and 22.0%, respectively. The anti-TB treatment history revealed dramatic influences on the sensitivity of culture(P < 0.0001). In fact, the treatment that lasted over 3 months also influenced the sensitivity of Xpert(P < 0.05). However, the treatment history did not affect the performance of remaining tests(P > 0.05). For rifampicin drug susceptibility test(DST), the anti-TB treatment showed only significant influence on the success rate of culture DST(P = 0.001), but not on those of Xpert and HRM tests(P > 0.05). Conclusion Other tests as well as culture should be considered for patients with TBLN having retreatment history or over 1-month treatment to avoid false negative results.CHE Nan Ying HUANG Shao Jun MA Yan HAN Yi LIU Zi Chen ZHANG Chen MU Jing ZHAO Dan QU Yang ZHANG Hai Qing LIU Zhi Dong XU Shao Fa 2017Biomedical and Environmental Sciences2017,30,6:6
18Epigenetic modification in histone deacetylase deletion strain of Calcarisporium arbuscula leads to diverse diterpenoids显示文摘Epigenetic modifications have been proved to be a powerful way to activate silent gene clusters and lead to diverse secondary metabolites in fungi. Previously, inactivation of a histone H3 deacetylase in Calcarisporium arbuscula had led to pleiotropic activation and overexpression of more than 75% of the biosynthetic genes and isolation of ten compounds. Further investigation of the crude extract of C. arbuscula Δhda A strain resulted in the isolation of twelve new diterpenoids including three cassanes(1-3), one cleistanthane(4), six pimaranes(5-10), and two isopimaranes(11 and 12) along with two know cleistanthane analogues. Their structures were elucidated by extensive NMR spectroscopic data analysis. Compounds 2 and 4 showed potent inhibitory effects on the expression of MMP1 and MMP2(matrix metalloproteinases family) in human breast cancer(MCF-7) cells.Jian Bai Rong Mu Man Dou Daojiang Yan Bingyu Liu Qian Wei Jun Wan Yi Tang Youcai Hu 2018Acta Pharmaceutica Sinica B2018,8,4:5

20Genetic and Antibiotic Resistance Characteristics ofCampylobacterjejuni Isolated from Diarrheal Patients,Poultry and Cattle in Shenzhen显示文摘Objective To investigate genetic and antibiotic resistance characteristics of Campylobacter jejuni(C. jejuni) isolated from Shenzhen. Methods Multilocs sequence typing and agar dilution methods were used to define the genotype and antibiotic resistance of C. jejuni, respectively. Results In total, 126 C. jejuni strains were isolated. The prevalence of C. jejuni was 5.3% in diarrheal patients. The prevalence in poultry meat(36.5%) was higher than that in cattle meat(1.1%). However, the prevalence in poultry cloacal swabs(27.0%) was lower than that in cattle stool(57.3%). Sixty-two sequence types were obtained, among which 27 of the STs and 10 alleles were previously unreported. The most frequently observed clonal complexes were ST-21(11.9%), ST-22(10.3%), and ST-403(7.1%). ST-21, ST-45, ST-354, ST-403, and ST-443 complexes overlapped between isolates from patients and cattle, whereas ST-45 and ST-574 complexes overlapped between isolates from patients and poultry. All C. jejuni were resistant to at least one antibiotic. The highest resistance rate was toward ciprofloxacin(89.7%), followed by tetracycline(74.6%), and nalidixic acid(69.0%). Conclusion This is the first report of the genotypes and antibiotic resistance of C. jejuni in Shenzhen. Overlapping clonal complexes were found between isolates from patients and cattle, and between patients and poultry.JU Chang Yan ZHANG Mao Jun MA Yan Ping LU Jing Rang YU Mu Hua CHEN Hui LIU Chu Yun GU Yi Xin FU Yan Yan DUAN Yong Xiang 2018Biomedical and Environmental Sciences2018,31,8:5
