Abnormal metabolism in vivo of uric acid leads to many diseases.Recent discovery shows that glucose transporter-like protein-9,which belongs to glucose transporter family not only transports glucose,but also plays an important role in the process of uric acid transport,which is also affected by pH,glucose,estrogen,etc.The variation of glucose transporter-like protein-9 results in metabolic diseases.Therefore,the study of glucose transporterlike protein-9 in uric acid transport and related drug will provide new ideas to control the development of hyperuricemia and related cardiovascular disease.

OBJECTIVE:To evaluate the clinical efficacy and safety of letrozole combined with traditional Chinese medicine for ovulation dysfunction induced by polycystic ovarian syndrome(PCOS). METHODS: 300 PCOS outpatients were randomized to 3 groups of 100 each: clomiphene citrate (CC) group (188 cycles);urinary gonadotropin (HMG) group (104 cycles) and letrozole (LE) group (155 cycles). The occurrence rate of mature follicle,ovulation rate,pregnancy rate,abortion rate,superfoetation-terata rate,cancellation rate,incidence of no dominant follicle forming and OHSS etc were compared between the two groups after treatment. RESULTS: 30 babies were born in CC group,34 in HMG group and 43 in LE group were born. The occurrence rate of mature follicles,ovulation rate and pregnancy rate in the LE group were higher than in either CC group or HMG group(P0.05);the superfoetation rate in HMG group was higher than in CC group or LE group(P

ObjectiveTo investigate the characteristics of autonomic nervous response of armymen with different mentalqualityuse the enhanced emotion regulationstrategies during fear emotion processes.Methods Mental Quality Questionnaire of Armymen was used to select participants from 818 armymen,screening out 30 armymen with low mental quality,30 armymen with moderate and 30 armymen with high.With elicitation of fear emotion,the participants adopted enhance emotion regulation strategies (cognition emphasis and emotion catharsis),and their blood volume pulse( BVP),skin conductance( SC ),normalized high frequency spectral component(HFnorm),standard deviation of all normal intervals(SDNN) and the recovery time of BVP and SC were recorded.Results ( 1 ) The different mental quality of army men activity in the autonomic physiological changes were not significant differences in resting state.(2) When using the cognition emphasis,the SC of different mental quality of armymen were reduced,and low mental quality of armymen( ( -0.67 ± 1.05 )μ.Ω),moderate mental quality of armymen ( ( - 0.49 ± 0.75 ) μΩ) had larger SC than high mental quality of armymen ( ( - 2.16 ± 2.18 ) μΩ ) ;high mental quality of armymen( ( - 2.17 ± 8.96) nU ) had lower HFnorm than the control( ( 6.96 ± 7.08 ) nU ).When using emotion catharsis,high mental quality of armymen ( ( 1.95 ± 6.58 ) nU ) had lower HFnorm than the control( (6.96 ±7.08)nU).(3)When using the cognition emphasis,low mental quality of armymen ((65.50 ±43.43 )s) had longer recovery time of BVP than high mental quality of armymen( (26.50 ± 25.72)s).When using emotion catharsis,low mental quality of armymen( (71.50 ± 48.36)mm Hg)had longer recovery time of BVP than high mental quality of armymen ( ( 21.00 ± 35.50 ) mm Hg) ; low mental quality of armymen ( ( 103.50 ± 38.01 ) s)had longer SC than moderate( (63.50 ±48.59)s) and high mental quality of armymen( (61.50 ±33.09) s).Conclusion The ability to regulate sympathetic in low mental quality group is weaker than the high mental quality group,although sympathetic can be suppressed when enhanced emotion regulation are adopted.

Objective To conclude and compare the technical characteristics and clinical efficacy of retroperitoneal and transperitoneal approach for robotic partial nephrectomy.Methods 418 patients received robotic partial nephrectomy conducted by one surgeon in the urology department of PLA General Hospital from 2013, December to 2015, October, including 157 cases in retroperitoneal approach and 261 cases in transperitoneal approach.There were no significant difference between the transperitoeal and retroperitoneal approach in patient age(51 years, 51 years, P=0.593), BMI(25.5 kg/m2,25.6 kg/m2, P=0.331), gender(male/female:111/46,186/75,P=0.184), location(left/right,80/77,123/138,P=0.575), tumor size(3.1cm,3.5cm,P =0.356), comorbidities, proportion of solitary kidney(11.5%, 9.6%,P=0.253) or bilateral tumors(1.3%,3.4%,P=0.179), RENAL score(6(5-8),6(5-8),P=0.083), ASA score(2 vs.2)(P=0.310) and preoperative serum creatinine(74.7 μmol/L,76.7 μmol/L, P=0.736).Patients in the retroperitoeal approach group were more likely to have abdomen surgery history (21.7%,14.2%,P=0.049).there was significant difference between two approaches in tumor location in the kidney ( anterior/posterior/others: 9/140/8, 212/36/13, P <0.001 ) Results The operation time (105min, 115min, P =0.041 ) and warm ischemia time ( 15min, 20min, P <0.001 ) were shorter and estimated blood loss(50ml,75ml,P<0.001) was less in the retroperitoneal group.No significant difference was observed in postoperative 24h blood loss(45ml,50ml,P =0.093), intraoperative transfusion rate (2.5%,6.5%,P=0.072) and collective system injury(24.8%,27.6%,P =0.539) between the two groups.Peritoneum break occurred in 25 cases in retroperitoneal group, which were repaired by Hem-o-lock.One intestinal injury occurred in transperitoneal group and was repaired intraoperatively.Three and nine cases in the retroperitoneal and transperitoneal group were converted to radical nephrectomy.One case in the transperitoneal group was found positive margin and received laparoscopic radical nephrectomy.Two liver injury and five spleen injury occurred in the transperitoneal group.For postoperative food intake(1 day, 2 days, P <0.001 ) , the length of indwelling drainage ( 3 days, 4 days, P <0.001 ) and the length of postoperative stay ( 5 days, 6 days, P =0.001 ) , the retroperitoneal group had one day shorter than the transperitoneal group.With the median following-up time of both group, 11 months (IQR:6-16) in RPRPN group and 12 months ( IQR: 7-19 ) , no subject with a tumor recovery or metastasis.Conclusions Retroperitoneal robotic partial nephrectomy is feasible and effective, which is similar to transperitoneal approach.The retroperitoneal approach is superior to transperitoneal approach for posterior, lateral and superior renal tumors.

Objective To analyze the genetic stability of master virus seed lots of live attenuated influenza vaccineA/17/California/2009/38(H1N1)andA/17/Perth/09/87(H3N2)strains.Methods The master virus seed lots were inoculated into chicken eggs for subculture.The complete genome of the 2nd, 3rd, 5th and 10th generations of viruses were amplified and sequenced.The genes encoding hemagglu-tinin ( HA) and neuraminidase ( NA) were compared with those of the WHO recommended circulating wild-type virus strains used for vaccine production in northern hemisphere during 2011-2012 influenza season.Six internal genes (PB2, PB1, PA, NP, M and NS) of each virus generation were compared with their master donor virus strain (A/Leningrad/134/17/57) for the evaluation of the genetic stability.Results The muta-tion rates of H1N1 and H3N2 strains after 10 passages were 0.035%and 0.022%, respectively.No muta-tions were found at the critical sites for controling thecold adapted ( ca) , temperature sensitive ( ts) and at-tenuated ( att) phenotypes.Conclusion The live attenuated influenza vaccine strains possessed high genet-ic stability as their tenth generations still shared 99% of homology with the original seed lots.All of the working virus seed lots met the requirements of Pharmacopoeia of the People′s Republic of China ( 2010 edition) .

Background::Post-operative acute kidney injury (AKI) is one of the most common and serious complications after major surgery and is significantly associated with increased risks of morbidity and mortality. This meta-analysis was conducted to evaluate the effects of perioperative dexmedetomidine (Dex) administration on the occurrence of AKI and the outcomes of recovery after non-cardiac surgery.Methods::The PubMed, Embase, Web of Science, and Cochrane Library databases were systematically searched for studies comparing the effects of Dex vs. placebo on kidney function after non-cardiac surgery, and a pooled fixed-effect meta-analysis of the included studies was performed. The primary outcome was the occurence of post-operative AKI. The secondary outcomes included the occurence of intra-operative hypotension and bradycardia, intensive care unit (ICU) admission, duration of ICU stay, and hospital length of stay (LOS). Results::Six studies, including four randomized controlled trials (RCTs) and two observational studies, with a total of 2586 patients were selected. Compared with placebo, Dex administration could not reduce the odds of post-operative AKI (odds ratio [OR], 0.44; 95% confidence interval (CI), 0.18-1.06; P= 0.07; I2= 0.00%, P= 0.72) in RCTs, but it showed a significant renoprotective effect (OR, 0.67; 95% CI, 0.48-0.95; P = 0.02; I2 = 0.00%, P = 0.36) in observational studies. Besides, Dex administration significantly increased the odds of intra-operative bradycardia and shortened the duration of ICU stay. However, there was no significant difference in the odds of intra-operative hypotension, ICU admission, and hospital LOS. Conclusions::This meta-analysis suggests that perioperative Dex administration does not reduce the risk of AKI after non-cardiac surgery. However, the quality of evidence for this result is low due to imprecision and inconsistent types of non-cardiac operations. Thus, large and high-quality RCTs are needed to verify the real effects of perioperative Dex administration on the occurrence of AKI and the outcomes of recovery after non-cardiac surgery.

Chromatin immunoprecipitation sequencing (ChIP-seq) and the Assay for Transposase-Accessible Chromatin with high-throughput sequencing (ATAC-seq) have become essential technologies to effectively measure protein–DNA interactions and chromatin accessibility. However, there is a need for a scalable and reproducible pipeline that incorporates proper normalization between samples, correction of copy number variations, and integration of new downstream analysis tools. Here we present Containerized Bioinformatics workflow for Reproducible ChIP/ATAC-seq Analysis (CoBRA), a modularized computational workflow which quantifies ChIP-seq and ATAC-seq peak regions and performs unsupervised and supervised analyses. CoBRA provides a comprehensive state-of-the-art ChIP-seq and ATAC-seq analysis pipeline that can be used by scientists with limited computational experience. This enables researchers to gain rapid insight into protein–DNA interactions and chromatin accessibility through sample clustering, differential peak calling, motif enrichment, comparison of sites to a reference database, and pathway analysis. CoBRA is publicly available online at https://bitbucket. org/cfce/cobra.
