Purpose To test the virus inactivation effect of water bath method at 60 ℃ for 10 hours and alcohol treatment for 3 hours which was used in the production of urinary trypsin inhibitor(UTI).Methods Sindbis virus,Pseudorabies virus(PRV) and poliovirus1(PV1) were used as indicated viruses in this test.After being added separately into the UTI raw material in 10% proportion,the viruses were treated with water bath at 60 ℃ for 10 hours and alcohol for 3 hours and then the samples of UTI were taken to inoculate the cell line for assay of cytopathic effect.Results The water bath at 60 ℃ for 10 hours could inactive Sindbis,PRV and PV1 in more than(6.503±0.102)LgTCID_(50),(6.42±0.158) LgTCID_(50) and(6.587±0.061)LgTCID_(50) respectively,and alcohol treatment for 3 hours could inactive Sindbis,PRV and PV1 in more than(5.88±0.204)LgTCID_(50),(6.378±0.268)LgTCID_(50) and(5.963±0.118) LgTCID_(50) respectively.No cytopathic effect was found in the cell line which was inoculated with treated samples after blind passage for three generations.Conclusion The water bath method at 60 ℃ for 10 hours and alcohol treatment for 3 hours which were used in the production of UTI had good effects on virus inactivation and the inactivation efficiency on Sindbis,PRV and PV1 was more than 6 LgTCID_(50)/mL.

Objective:To evaluate the efficacy and safety of capecitabine or S-1 combined with oxaliplatin or cisplatin in the treat-ment of advanced gastric cancer. Methods:Six databases including Cochrane Library, Pubmed, Embase, CNKI, VIP and WanFang were retrieved. Randomized controlled trials ( RCT) in the treatment of advanced gastric cancer were involved for the quality assess-ment and Meta-analysis. Results:A total of 14 RCT involving 1 051 patients were included. There were no significant differences in the total effective rate, complete remission rate and partial remission rate between the two groups(P>0. 05). In the safety evaluation, the incidence of hand-foot syndrome was higher in capecitabine-based regimens than that in S-1-based regimens[RR=2. 59,95%CI (1. 61,4. 17),P<0. 000 1], while the incidence of stomatitis was lower in capecitabine-based regimens[RR=0. 64,95%CI(0. 50, 0. 82),P=0. 000 4]. The other adverse reactions such as nausea and vomiting, diarrhea,neuropathy,dysfunction of liver and kidney, anemia, leukopenia, neutropenia and thrombocytopenia exhibited no significant differences between the two groups(P>0. 05). Con-clusion:Capecitabine combined with oxaliplatin or cisplatin has similar efficacy with S-1 combined with oxaliplatin or cisplatin in the treatment of advanced gastric cancer, and the incidence of hand-foot syndrome is higher in capecitabine-based regimens and the inci-dence of stomatitis is higher in S-1-based regimens.

Objective To systematically evaluate the effects of albumin compared with crystalloids on fluid resuscitation for adults with severe sepsis and septic shock.Methods The six databases as follows:Cochrane Library,Pubmed,Embase,CNKI,VIP and Wanfang,were retrieved by computer,from their inception to November,2015.Randomized controlled trials(RCT) in the treatment of adult patients with severe sepsis and septic shock were included for quality assessment and Meta-analysis was performed by using RevMan5.3 software.Results A total of 4 RCTs involving 3 862 participants were included.No differences were found between albumin and crystalloids resuscitation with respect to 28-day mortality[RR=0.95,95%CI(0.86,1.05),P=0.33],90-day mortality[RR=0.95,95%CI(0.86,1.05),P=0.33],duration of stay in ICU,duration of hospital stay,duration of mechanical ventilation and renal replacement therapy.Conclusion In that meta-analysis,the effects of fluid resuscitation with albumin or crystalloids were not significantly different in adults with severe sepsis and septic shock.

Objective To investigate T cell receptor(TCR)variable β(BV)chain usage at the maternal-fetal interface and explore the relationship between the skewed TCR BV usage and unexplained recurrent spontaneous abortion(BSA).Methods Eighteen cases with unexplained RSA,together with matched 41 women with normal pregnancies in first trimester from Renji Hospital,Shanghai Jiao Tong University were studied.A high-resolution spectrum typing analysis of complementarity-determining region 3 (CDR3)was used to detect and compare the degree and frequency of TCR BV family expression in deciduas between RSA patients and normal controls.Results(1)The expression degree of BV19(0.029±0.031 vs.0.013±0.010,P=0.038)in RSA group showed a higher usage,while BV5.2(0.040±0.035 vs.0.067±0.052,P=0.046)showed a significantly lower usage when compared with normal controls.No significant difference in the expression of the other TCR BV families between RSA and controls were observed(P>0.05).(2),TCR BV2,3,6,and 7 were the four most common BV families in deciduas of patients with RSA and normal controls,whose frequencies were all mors than 50%.In RSA group,higher frequencies of BV15 (33.3%vs.7.3%,P=0.018),BV19(38.9%vs.14.6%,P=0.049)and BV20(33.3%vs.7.3%,P=0.018)were observed;meanuhile lower frequencies of BV4(33.3%vs.65.9%,P=0.026)and BV7 (66.7%vs.92.7%.P=0.018)distributions were observed.The other TCR BV families did not display significantly different freqencies of distribution(P>0.05).Conclusions It is suggested that a significant skewed TCR BV family occurs at the maternal-fetal interface in patients who undergo abortion.The specific skewed usages of TCR BV might be associated with the susceptibility to unexplained pregnancy loss.

OBJECTIVE:To study the relative bioavailability,pharmacokinetics and bioequivalence of domestic nisoldipine tablets in healthy volunteers.METHODS:A single oral dose of 10 mg test and reference nisoldipine tablets were given to 24 male healthy volunteers in an open randomized 2?2 latin square design.The plasma concentrations of nisoldipine at different time points were determined by LC-MS and the pharmacokinetic parameters of the two kinds of tablets were computed and their bioequiavailability was evaluated.RESULTS:The main pharmacokinetic parameters of the test vs.reference formulations of nisoldipine in 24 healthy volunteers were as follows:Cmax(2.94?2.78)ng?mL-1 vs.(3.22?2.16)ng?mL-1,tmax(1.70?1.00)h vs.(1.40?1.00)h,t1/2(6.81?4.11)h vs.(5.55?2.35)h,AUC0～24(10.60?7.70)ng?h?mL-1 vs.(9.90?6.76)ng?h?mL-1,AUC0～∞(11.30?7.90)ng?h?mL-1 vs.(10.20?7.00)ng?h?mL-1.The relative bioavailability of domestic nisoldipine tablets was(110.3?30.8)%.CONCLUSION:The reference preparation and the test preparation of nisoldipine tablets were proved to be bioequivalent.

Objective To study the effect of HCV receptors′sequence on virus entry based on the two-dimensional structure and via tandem expression of HCV receptors on mouse hepatocytes.Methods The construced recombinant expression vectors pCDH-hLDLR-hSR-BⅠ-hCD81-GFP, pCDH-hLDLR-hCD81-hSR-BⅠ and pCDH-hCLDN-1-hOCLN-DsRed were cotransfected into 293FT cells with package vectors.The collected recombinant lentivirus expressing hCLDN-1-hOCLN was concentrated and attacked mouse hepatocytes.The transgenic mouse hepatocytes with tandem overexpression of CLDN-1 and OCLN were established after G418-selection.The transduced cells LSCCO/Hepa1-6 and LCSCO/Hepa1-6 were sorted via flow cytometry and puro-G418-selection after recombinant lentivirus expressing hLDLR-hSR-BⅠ-hCD81 and hLDLR-hCD81-hSR-BⅠattacked Hepa1-6 respectively.The infectivity of transduced mouse hepatocytes LSCCO/Hepa1-6 and LCSCO/Hepa1-6 to HCV was analyzed via direct-infection of serum-derived virus.Furthermore, the effect of HCV receptors′sequence on virus entry was studied.Results Both LSCCO/Hepa1-6 and LCSCO/Hepa1-6 enhanced HCV-cell binding.The transduced mouse hepatocytes LSCCO/Hepa1-6 had more HCV endocytosis.Conclusion SR-BⅠhas priority over CD81 in HCV entry in the early stage.

Objective To discuss the effects of electroacupuncture intervention in different acupoints of rats models with diarrhea type irritable bowel syndrome (D-IBS).Methods The rat models were established with acute and chronic stimulation. The rats were divided into the normal control group, model group, “Taichong” (LR3) + “Zusanli” (ST36) group, and “Tianshu” (ST25) + “Zusanli” (ST36) group. Electroacupuncture was applied to bilateral corresponding acupoints for 20 minutes, every other day for 7 times. The physical signs of each rat were observed. The contents of 5-HT, NE and CGRP in the rats’ plasma were detected by sandwich ELISA. Results Compared with the normal group, the contents of 5-HT and NE in the model group were obviously higher and the content of CGRP decreased (P<0.05). Compared with the model group, the contents of 5-HT and NE in all treatment groups were lower and the content of CGRP increased (P<0.05). There was no difference between the “Taichong” (LR3) + “Zusanli” (ST36) and “Tianshu” (ST25) + “Zusanli” (ST36) groups.Conclusion The mechanism of electroacupuncture may be realized through lowering the contents of 5-HT and NE in the model rats and increasing the content of CGRP to treat D-IBS.
