Objective To observe effect of Yaotui Litongsan on nerve-related behavior of autograft of nucleus pulposus to cavum epidurale in rats.Methods Fifty normal Wistar rats were randomly divided into five geoups:the sham operated group (A),injury model group (B),Yaotongning treat group (C),high dose and low dose group (Yaotui Litongsan treat,D and E),10 rats in each group.Autogenous nucleus pulposus was removed from the coccygeal vertebral and placed into the back of L5～6 nerve roots of left cavum epidurale,making the non-compressive model with transplanted autogenous nucleus pulposus.The mechanical withdraw threshold and thermal withdraw latency were determined.Results The significant mechanical hyperalgesia was showed in the rats of B,C,D,E groups postoperatively,but it was lighter in C,D,E groups than in B group (P

Objective To understand the epigenetic regulations of P16 during cellular replicative senescence and premature senescence induced by hydrogen peroxide of human embryonic lung fibroblasts(HEFs).Methods The normal HEFs were divided into young cells(22 PDL),mid-aged cells(35 PDL)and replicative senescent cells(49 PDL)during replicative senescence.The synchronously cultured 22 PDL HEFs were exposed for 2 h to 400?mol/L H_2O_2 at half confluence on daily basis.The procedure lasted for 4 consecutive days.And then the treated cells were cultured for another 7 days,called premature senescent cells.The mRNA level of P16 was detected by fluorescence quantitative PCR.The methylation level in the promoter region -846～-639 bp was observed by methylation-specific PCR(MSP).The histone modifications was detected by chromatin immunoprecipitation-QPCR assay,including acetylation for H3,H4 and methylation for H3(Lys4)and H4(Lys20).Results In the process of cellular senescence,the mRNA level of P16 decreased in mid-aged cells,but increased significantly in both replicative and premature senescent cells compared with that of young cells(P

Objective To study the therapeutic effect of Shengfuling on the healing of various skin defect of human body.Methods Sixty cases of various skin defects were randomly divided into the treated group and the control group,which were treated by Shengfuling and normal healing after debridement,respectively.The healing time of defect areas and skin injury degrees was observed.The post-healing skin quality(color,hardness,tension) of the two groups were compared.Results The treated group had better effect than the control group in skin healing velocity and post-healing skin quality(P

OBJECTIVE:To ensure patients'rights of knowing the fact of medication.METHODS:The characteristics of medical care and the chief problems existed at present were analyzed.The significance and the necessity of ensuring patients'rights of knowing the fact in medication in hospital were discussed and some specific measures were proposed.RESULTS&CONCLUSION:Ensuring patients'rights of knowing the fact in medication embodies hospital's demand for"taking people as top priority",building a harmonious society,upgrading hospital's image and promoting rational drug use,which deserves great attention from the relevant hygiene authorities and hospital leaders.

OBJECTIVE: To discuss the relationship between drug price policy and the medical market order in China. METHODS: Considering Chinese medical market order, problems in drug price policy of our country were analyzed. RESULTS & CONCLUSIONS:Drug price policy of China is the one of key factor for the current medical market disorder, the formulation of which should be based on national condition and under governmental control.

OBJECTIVE:To discuss the thoughts over the event of“armillarisin A”produced by Qiqihar No.2Pharmaceut ical Co.Ltd.METHODS:Citing the event of“armillarisin A”produced by Qiqihar No.2Pharmaceutical Co.Ltd.as example,we analyzed problems occurred in the process of production and management of pharmaceuticals and traced the root causes.RESULTS&CONCLUSIONS:Pharmaceutical enterprises should bear in mind their social responsibility and leave no loophole in the control and supervision of drugs,they should draw lessons from this event and prevent the similar event from happening again by working out effective measures to tighten controls on the quality of drug production,registering and approval,circulation,ADR reporting,etc.

Objective To analyze the differences of adverse drug reactions between children and adults caused by Tanreqing injection,and provide reasonable application of Tanreqing injection.Methods Retrospective research method were adopted to screen out the adverse drug reaction reports caused by Tanreqing injection from drug ADR reports of Drug ADR Monitoring Center affiliated to the Second People's Hospital of Gansu Province from January 2010 to October 2012.Figures of children and adults who used Tanreqing injection were analyzed separately.Results A total of 603 children used Tanreqing injection,among which 5 children appeared ADR (0.83％).A total of 4395 adult used of Tanreqing injection,among which 4 appeared in ADR (0.09％).There was statistical difference between the two groups (x2 =16.07,P＜ 0.05) The incidence rate of ADR in males was more than females either in the adults or in children.Hypersensitivity was the most common ADR.Conclusion ADR of Tanreqing injection in Children was significantly higher than adults.Tanreqing injection should be used carefully and rationally.

OBJECTIVE: To investigate the possible role of Caspase 3 and Bcl - 2 in arsenic trioxide(As2 O3) - induced apoptosis of Namalwa cell line .METHODS: Cell apoptosis was assessed through agarose gel elecrophroresis and the double staining of Annexin V and propidium iodide(PI), of which fluorescent intensities were measured on flow cytometer.Namalwa cells were treated with As2 O3 and DEVD - CHO, a selective inhibitor of Caspase 3,and the changes of expression of Caspase 3 and Bcl - 2 were observed .RESULTS: As2 O3 up - regulated Caspase 3 protein and down - regulated Bcl - 2 protein. DEVD-CHO inhibited the apoptosis induced by As2O3. but it had no effect on down - regulation of Bcl - 2 protein induced by As2O3.CONCLUSION:The activation of Caspase 3 may play a role in mediating apoptosis induced by As2O3 in Namalwa cells.

OBJECTIVE:To investigate the preparation technic and method of quality control of Xinyoukexing tincture(XYKX) METHODS:To determine the content of Valaciclovir by spectrophotography,and podophyllotoxin by dual-wavelength spectrophotography RESULTS:In the range of 14 88～34 72?g/ml,the Valaciclovir concentration in XYKX was in direct proportion to the absorption at 310 4nm,C=44 5 905A+1 7 556,r=0 9 998 In the range of 17 50～50 12?g/ml,the podophyllotoxin concentration in XYKX was in direct proportion to the absorption at 292nm,C=97 7 981Ap292+1 3 614,r=0 9 999,AP292=As292-As325 CONCLUSION:The preparation technic of XYKX is simple and the method of quality control is feasible

OBJECTIVE:To observe the effect of Guben yangxue oral liquid on cyclophosphamide (CTX)-induced suppression of the immune and hematopoietic system in mice. METHODS:Immunosuppressive model mice were induced by intraperitoneal injection of CTX 50 mg?kg-1. Different dose groups were Guben yangxue oral liquid at the same time with Zhenqi fuzheng capsules as control. Several index such as peripheral blood cells, the weight of immune organ, serum hemolysin were determined. RESULTS:The levels of white blood cells (WBC,87.3、26.3、7.96 g?kg-1), lymphocytes (L,87.3 g?kg-1), neutrophils (N,87.3、26.3、7.97 g?kg-1), hemoglobin (Hb,87.3、26.3 g?kg-1), red blood cell (RBC,87.3、26.3 g?kg-1), platelets (PLT,87.3、26.3 g?kg-1), sp- leen index(87.3,26.3 g?kg-1), thymus index(87.3 g?kg-1), serum hemolysin (87.3、26.3、7.96 g?kg-1)in CTX-induced immunosuppressive mice were increased after administrated of Guben yangxue oral liquid. CONCLUSION:Guben yangxue oral liquid can enhance the non-specific immunity and humoral immune function of CTX-induced immunosuppressive mice, and it can improve CTX-induced hematopoietic dysfunction significantly.
