Objective To investigate the roles of theaflavins(TFs) in airway mucus hypersecretion induced by human neutrophil elastase(HNE). Methods Human lung adenocarcinoma cell A549 was stimulated by HNE for mucus hypersecretion,and TF monomers(TF1,TF2 and TF3) were used for intervention.The effects of TF monomers on viability of A549 cells were examined by MTT method.After the effective doses of TFs were determined,A549 cells were divided into 4 groups for experiment.In control group,A549 cells were cultured with serum-free medium.In HNE treatment group,A549 cells were treated with HNE(50 nmol/L) for 24 h.In TF monomer intervention groups,A549 cells were pre-treated with TF1,TF2 or TF3(50,100 or 200 ?g/mL) for 24 h,and were then treated with HNE for another 24 h.In AG1478 intervention group,A549 cells were pre-treated with AG1478(5 ?mol/L),an epidermal growth factor receptor blocker for 30 min,and were then treated with HNE for another 24 h.The changes in mucin(MUC) after treatment by different doses of TF1,TF2 and TF3,and by TF3(200 ?g/mL) for different time(12 h,24 h and 36 h) were detected.The changes in MUC5AC mRNA expression and MUC5AC protein expression were detected by RT-PCR and ELISA,respectively. Results The MUC5AC mRNA expression and protein expression in HNE treatment group were significantly higher than those in control group(P

Objective To study the effect of cypermethrine (CP) on the reproductive organs of female rats.Methods Fifty female SD rats (90-110 g) were randomly divided into 5 groups,negative control (earthnut oil),three CP treatment groups(20,40 and 80 mg/kg body) and positive control (E_2 100?g/kg body),treated by gavage,once a day,for 28 consecutive days.Results Compared with the negative group,the opening of vagina in different cypermethrine groups were significantly moved up in the first week (P

Objective The aim of this paper is to know about the pollution of microcystin-LR(MC-LR)in Fenhe First reservoir and Fenhe Second reservoir in Taiyuan and provide reference for making the policy of prevention microcystin-LR pollution.Methods During the low water period(May,2005)and common period(Oct,2005),5 liter water was sampled in the entrance,the center and the exit in Fenhe First reservoir and Fenhe Second reservoir respectively.The concentrations of MC-LR in two reservoirs were determined by the high-performance liquid chromatography(HPLC).Results The average concentration (0.875 ?g/L)of MC-LR in low water period was 3 time of that(0.283 ?g/L)in common period in Fenhe First reservoir.The average concentration(0.815 ?g/L)of MC-LR in low water period was 17 time of that(0.048 ?g/L)in common period in Fenhe Second reservoir.The level of MC-LR in the entrance was the highest,that in the exit was the lowest,that in the center was middle. The concentration of MC-LR of the entrance in low water period was more than the MC-LR limit(1 ?g/L)in Life drinking water hygienic guide(2001).Conclusion MC-LR pollution has been found in Fenhe First reservoir and Fenhe Second reservoir and the pollution is serious in low water period.

OBJECTIVETo investigate the influence of male age on the pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 7,533 cycles of IVF-ET performed between January 1, 2009 and October 31, 2013. We divided the samples into three groups according to the female age (< 30, 30-34, and 35-38 yr), each again subdivided into six groups based on the male age (< 30, 30-32, 33-35, 36-38, 39-41, and ≥ 42 yr). We compared the rates of implantation, pregnancy, miscarriage, and live birth among different age groups.

RESULTSThere were no statistically significant differences in basal E2, FSH, endometrium thickness on the day of hCG administration, number of oocytes retrieved, and days of embryo transfer among different male age groups (P > 0.05). The implantation rate showed an age-dependent decrease in the < 30, 30-32, 33-35, 36-38, 39-41, and ≥ 42 yr male groups, 41.1, 42.0, 39.5, 31.3, 40.7, and 48.6% among the women aged < 30 years (P < 0.05), 40.3, 36.4, 35.1, 35.3, 29.4, and 37.3% among the women aged 30-34 years (P < 0.05), and 48.2, 17.8, 25.3, 23.5, 22.1, and 23.8% among the women aged 35-38 years (P < 0.05). The miscarriage rate was significantly higher in the ≥ 39 yr than in the 30-32 and 33-35 yr male age groups among the women aged 30-34 years (P < 0.05), but showed no remarkable differences among the other male age groups in the women aged < 30 and 35-38 years (P > 0.05). No statistically significant differences were observed in the rates of pregnancy and live birth among different male age groups (P > 0.05).

CONCLUSIONMale age has some influence on the rates of implantation and miscarriage but not on the rates of pregnancy and live birth in IVF-ET.

Objective:To study the clinical efficacy ofYiqi Huoxue Decoction in the treatment of children with spleen and kidney deficiency type nephrotic syndrome.Methods:A total of 80 children with spleen and kidney deficiency type nephrotic syndrome in our hospital from June 2014 to October 2016 were enrolled in this study.The subjects were divided into control group (n=40) and treatment group (n=40) according to the random number table method.The control group was treated with prednisone,and the treatment group was treated with prednisone combined with Yiqi Huoxue Decoction,the two groups were treated for 4 months.The clinical efficacy of the two groups were evaluate.The 24h proteinuria,total cholesterol (TC),plasma albumin (Alb),and renal function parameters including blood urea nitrogen (BUN),serum creatinine (Scr),and serum creatinine clearance (Ccr) of the two groups before and after treatment were compared.Results:The total effective rate of the treatment group was 95.00％,which was significantly higher than 67.50％ of the control group,the difference was statistically significant (P＜0.05).The 24h proteinuria,TC,BUN and Scr of the two groups after treatment were significantly lower than before treatment,the Alb,Ccr of the two groups were significantly higher than before treatment,and above indexes in treatment group were better than the control group,the differences were statistically significant (P＜0.05).Conclusion:Yiqi Huoxue Decoction have good clinical efficacy in the treatment of children with spleen and kidney deficiency type nephrotic syndrome,which can obviously improve children renal function,and is worthy of clinical application.

OBJECTIVETo study the effect of the active fraction of Tiaoxin recipe (TXR-A), in inhibiting long-term potentiation (LTP) induced by beta amyloid protein (beta-AP) in CA1 area of rats' hippocampal slices.

METHODSThe population spike (PS) in CA1 area of hippocampal slices incubated in different medium was recorded before and after LTP was evoked by a 100 Hz, 100 trains high frequency stimulation (HFS), using extracellular microelectrode recording techniques.

RESULTSThe amplitude of PS significantly decreased after HFS in hippocampal slices incubated in medium containing 0.2 micromol/L beta-AP for more than 1.5 hour, as compared with that incubated in normal cerebrospinal fluid, the difference was significant, suggesting that beta-AP could inhibit LTP in hippocampal slices. The average amplitude of PS in slices incubated in beta-AP containing medium could be significantly enhanced by adding high-concentration TXR-A or TXR into the medium, and TXR-A showed a better effect of enhancing than that of TXR, indicating that TXR-A could increase the amplitude of LTP.

CONCLUSIONTXR-A may be the chief ingredient extracted from TXR for improving beta-AP induced LTP in CA1 area of rats' hippocampus, to antagonise the inhibition of beta-AP on LTP is possibly one of the mechanisms for its intelligence benefiting action.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.
