Objective To assess the efficacy and safety of topiramate monotherapy in the treatment of alcohol de?pendence. Methods The Cochrane library, PunMed, EMBase, CNKI, VIP and CBM database were searched to collect the randomized contolled trials (RCTs) of topiramate monotherapy to compare with placebo or positive control drug in al?cohol dependence. Data were extracted from the included literatures after the literatures’qualities were assessed. The meta-analyses were conducted with RevMan 5.2 software. Results Thirteen trials were included. Compared with place?bo, topiramate reduced score of obsessive compulsive drinking scale(MD=-5.90,95%CI:-10.99~-0.82,P=0.02), de?creased drinks per drinking day(MD=-6.94,95%CI:-12.20~-1.68,P=0.01), and increased percentage of days absti?nent(MD=15.36,95%CI:4.15~6.56,P<0.01). The incidence of paraesthesia, taste perversion, weight loss, memory or concentration impairment, dizziness, psychomotor retardation in topiramate group was higher. But the incidence of other adverse events was similar between groups. Compared with naltrexone, topiramate significantly postponed the days to first relapse(MD=2.10,95%CI:0.23~3.97,P=0.03). The adverse events were similar between groups. Conclusions Topira?mate in treatment of alcohol dependence is effective and safety.

The Sonic hedgehog (SHH) signaling pathway plays a pivotal role in neurogenesis and brain damage repair. Our previous work demonstrated that the SHH signaling pathway was involved in the neuroprotection of cortical neurons against oxidative stress. The present study was aimed to further examine the underlying mechanism. The cortical neurons were obtained from one-day old Sprague-Dawley neonate rats. Hydrogen peroxide (H(2)O(2), 100 μmol/L) was used to treat neurons for 24 h to induce oxidative stress. Exogenous SHH (3 μg/mL) was employed to activate the SHH pathway, and cyclopamine (20 μmol/L), a specific SHH signal inhibitor, to block SHH pathway. LY294002 (20 μmol/L) were used to pre-treat the neurons 30 min before H(2)O(2) treatment and selectively inhibit the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. The cell viability was measured by MTT and apoptosis rate by flow cytometry analysis. The expression of p38, p-p38, ERK, p-ERK, Akt, p-Akt, Bcl-2, and Bax in neurons was detected by immunoblotting. The results showed that as compared with H(2)O(2) treatment, exogenous SHH could increase the expression of p-Akt by 20% and decrease the expression of p-ERK by 33%. SHH exerted no significant effect on p38 mitogen-activated protein kinase (p38 MAPK) pathway. Blockade of PI3K/Akt pathway by LY294002 decreased the cell viability by 17% and increased the cell apoptosis rate by 2-fold. LY294002 treatment could up-regulate the expression of the pro-apoptotic gene Bax by 12% and down-regulate the expression of the anti-apoptotic gene Bcl-2 by 54%. In conclusion, SHH pathway may activate PI3K/Akt pathway and inhibit the activation of the ERK pathway in neurons under oxidative stress. The PI3K/Akt pathway plays a key role in the neuroprotection of SHH. SHH/PI3K/Bcl-2 pathway may be implicated in the protection of neurons against H(2)O(2)-induced apoptosis.

The metabonomics method was used to study the intervention effect of Psoraleae Fructus and Myristicae Semen in "Ershen pill" on the changes in serum endogenous metabolites in spleen-kidney Yang deficiency diarrhea rats before and after processing, screen out differentiated metabolites related to spleen-kidney Yang deficiency diarrhea and explore the metabolic patterns related to spleen-kidney Yang deficiency diarrhea and the processing synergy mechanism of Psoraleae Fructus and Myristicae Semen in "Ershen pill". Efforts were made to detect SOD and MDA of each group, test rat serum metabolic fingerprints in different stages by using GC-MS, analyze by PCA and PLS-DA methods and screen out potential biomarks through VIP and t test. The results revealed that "Ershen pill" could enhance the level of SOD and decrease the level of MDA and identified 10 differentiated metabolites related to spleen-kidney Yang deficiency diarrhea. Compared with the model group, all of metabolites recovered to varying levels after being intervened with "Ershen pill", with the best effect shown in the "Ershen pill" IV group (salt-processed Psoraleae Fructus + bran-roasted Myristicae Semen). It is speculated that that Psoraleae Fructus and Semen Myristicae in "Ershen pill" show a synergistic effect by inhibiting peroxide, improving aglucolipid, amino acids and energy metabolism, with multiple target sites.

The objective of this study is to explore the application possibility of chitosan/pcDNA-EGFP-TGFPbeta1 nanoparticles in the transfection of synovial-derived mesenchymal stem cells (SDMSCs). Chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles were fabricated through method of ionic crosslinking. The SDMSCs were harvested from rabbit joints and cultured to passage 3. The SDMSCs were then transfected with chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles. Scanning electronic microscope (SEM) was employed to detect the shape and diameter of the nanoparticles. The transfected SDMSCs were examined under the fluorescence microscope and detected through the flow cytometry (FCM). The SEM examination showed that the contour of the fabricated chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles was round and its average diameter was 50 nm. After being cultured for 48 h, the SDMSCs transfected by chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles could be detected under the fluorescence microscope, and the live SDMSCs could also be examined through FCM. The transfection rate was 8% - 10%. Therefore, it suggested that the chitosan/pcDNA-EGFP-TGFbeta1 nanoparticles fabricated through the method of ionic crosslinking could transfect the SDMSCs, but the transfection rate should be improved.

BackgroundThe quest to look for seed cells is a hot spot of cornea transplant research in solving the problem of the lack of donor. Bone marrow mesenchymal stem cells(BMSCs) have been successfully induced into retinal ganglion cells(RGCs) in vivo,but the successful induction of BMSCs into corneal endothelial cells has not been reported.Objective This experiment was to study the transplantation of BMSCs on corneal endothelial surface using the splitting Descemet's membrane. MethodsFour healthy adult rhesus monkeys were divided into the experimental group ( 3 monkeys) and control group ( 1 monkey). Mesenchymal stem cells (MSCs) were isolated from bone marrow by density gradient centrifugation combined with adhering means. The cultured cells were identified by flow cytometry and its ability to differentiate was determined by allowing them to differentiate into adipocytes in vitro and labeled by 5-bromodeoxyuridine ( BrdU ) for subsequent identification. Corneal grafts of 7 mm in size with tearing of the Descemet' s membrane were prepared in the experimental group and control group. After labeling by 5-bromodeoxyuridine( BrdU ) ,cultured cells were transplanted onto the endothelial surface of cornea grafts in the experimental group, but no cultured cells were seeded in the graft of the control group. The corneal grafts were then sutured in situ, and were removed 1,2 or 3 months after operation to examine the distribution and connection between transplanted cells and their morphologic changes under the electron microscope. Results High purity MSCs were harvested by density gradient centrifugation combined with adhering method. Cultured cells reached confluency after 12 to 16 days, presenting with a spindle shape and parallel or swirling arrangement. Flow cytometry analysis showed that 94.26% of cells were positive for CD29,7. 51% for CD34 and 4. 02% for CD45. Larger nuclei filled with plastosomes, golgiosomes and rough endoplasmic reticula were found on the graft under the transmission electron microscope( TEM ). After 3 weeks, MSCs were differentiated into adipocytes where Oil Red O staining resulted in an orange-red staining in the cytoplasm and blue staining in the nuclei. The transplanted cells attached loosely on the endothelial surface of the corneal graft and came in contact with each other in one month. The shape of the cells appeared as spindle-shaped and polygonal after 2 months and became tightly packed after 3 months. The positive cells retained the BrdU label and presented with brown nuclei. No endothelia cells grew in the cornea graft in the control group, with an absence of BrdU labeling. Conclusions Mesenchymal stem cells can be transplanted onto the corneal endothelial surface successfully and form a monolayer using the centrifugation method, and present with good survival and proliferation ability.
