The aim of this study is to investigate the effect of fluoxetine (FLX) on the expressions of BDNF and Bcl-2 in the hippocampus, the amygdala and the prefrontal cortex of conditioned fear (CF) model mice. Forty eight mice were randomly divided into three groups, normal control group, CF stress group and FLX-pretreated CF group. The FLX-pretreated CF group was given FLX (10 mg x kg(-1) x d(-1)) for 7 days before CF stress. After CF stress model was established, all mice were given behavioral experiments to test whether FLX impaired or improved the auditory and contextual fear conditioning. Then mice were sacrificed. The expressions of BDNF and Bcl-2 were detected by Western blotting. The results showed that the freezing time of FLX-pretreated CF group was significantly lower than that of CF group; FLX pretreatment up-regulated the expression of Bcl-2 in the hippocampus at 1 d after CF stress (P < 0.001), but no significant differences was observed at 7 d; BDNF significantly increased in the hippocampus at 7 d (P < 0.001), but no differences at 1 d; the expressions of BDNF and Bcl-2 in the amygdala and the prefrontal cortex were of no obvious differences between CF group and FLX-pretreated CF group at 1 d or 7 d after CF stress. Parallel to these changes, pretreatment with FLX could affect histopathologic changes induced by CF stress. Furthermore, the results indicated that FLX pretreatment could protect against CF stress-induced neurological damage via the activation of BDNF and Bcl-2 in hippocampus.

[Objective]To investigate the mechanism of Qingre Yiqi Tongluo(QRYQTL) fang in treating the diabetic nephropathy. [Methods]60 Sprague-Dawleg rats were divided into normal control group(N), Diabetic nephropathy model group(M) (model rats were prepared by intraperitoneal injection with STZ after unilateral nephrectomy), then the model rats were assigned into model control group, QRYQTL fang treatment group(Q) and Irbesartan treatment group(I). After 12 weeks of the treatment, the contents of superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-Px) and malondialdehyde (MDA) in renal tissue were examined by enzyme linked immunoassay(ELISA); the glomerular area(GA), mesangium area(MA),MA/GA, mean width of the podocyte foot processes(FPW) ,foot process fusion rate(FPFR) and average thickness of glomerular basement membrane(GBMT) were measured. [Results]Compared with N group, the contents of MDA in kidney homogenate and the GA,MA, FPW,FPFR,GBMT were markedly increased (P<0.01or P<0.05),the contents of SOD,CAT, GSH-Px and MA/GA were significantly decreased( P<0.01or P<0.05). QRYQTL fang reduced the level of MDA and decreased the GA, FPW, FPFR and GBMT(P<0.01or P<0.05). Compared with I group ,the QRYQTL fang was superior to Irbesartan in reducing the MDA, FPFR as wel as increasing the SOD,CAT(P<0.05).[ Conclusions]QRYQTL fang has a protective effect on the experimental diabec-tic nephropathy rats. The mechanism may be related to inhibiting oxidative stress, improving the body ’s antioxidant ability and al eviating the glomerular morphologic injury.

OBJECTIVE:To provide empirical reference for protecting the supply of clinical drugs. METHODS:Literature re-view was combined with the conditions of drugs that lost the bidding in the centralized bidding in Anhui province to determine the short drugs need to investigate. Questionnaire was adopted to investigate the situations and reasons of short drugs in 5 third-grade class-A hospitals of 5 areas in Anhui province from Nov. 2013 to Oct. 2014. RESULTS:A total of 5 questionnaires were sent out, and 5 were received with effective response rate of 100%. There were totally 54 short drugs in the 5 third-grade class-A hospitals, including the most serious shortage of drugs for neurocirculatory system,accounting for 20.37%. Shortage was mainly due to the low price of drugs,accounting for 48.15%,and insufficient supply,less suffering patients/low dosage and other reasons. CON-CLUSIONS:In view of the shortage of drugs,government departments should improve the drug pricing and bidding policy,pro-duction enterprises should enhance the enterprise production and development capabilities,business companies should optimize the distribution pattern of network and medical institutions should establish drug management system with a clear division of power and responsibility to relieve the drug shortages.

Objective To systematically evaluate the influence of acupuncture-moxibustion on the peroneal nerve conduction velocity in type 2 diabetic peripheral neuropathy (DPN), and to provide clinical references for acupuncture-moxibustion treatment for DPN.Method By searching the CBM, CNKI, VIP, Wanfang, Pubmed, Springer and Medline databases, randomized controlled trials (RCT) of acupuncture-moxibustion for the type 2 DPN published from January 2000 to January 2014 were retrieved and the relevant data of the peroneal nerve conduction velocity were collected for methodological evaluation. RevMan 5.1 software was adopted to conduct the meta-analysis.Result Totally 10 RCTs were recruited with 685 cases involved, including 355 cases in the treatment group and 330 cases in the control group. The meta-analysis results indicated that acupuncture-moxibustion can produce a better effect in improving the motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of peroneal nerve in type 2 DPN than the treatments used in the control group, and the differences were statistically significant between the two groups [MD=3.55, 95%CI (0.79, 6.31); MD=4.10, 95%CI (0.22, 7.99)].Conclusion Acupuncture-moxibustion can improve the peroneal nerve conduction velocity in type 2 DPN, and thus is worth application in clinic. Due to the limitation of the included studies, such as small sample size and low quality of the articles and high probability of bias, RCTs of large sample size and high quality are required to confirm the above conclusions.
