Objective To assess the long-term efficacy and safety of mid-dosage (13～15 mg?kg-1?g-1) ursodeoxycholic acid (UDCA) treatment for primary biliary cirrhosis (PBC). Methods A systematic review of all randomized controlled trials (RCT) comparing UDCA with placebo was performed. Results Seven trials including 1038 patients were assessed. UDCA could significantly improve liver biochemistry, but had no effect on pruritus and fatigue. In the patients with initial stage Ⅰ-Ⅱ, there was a significant decrease in the histologic progression after treatment with UDCA for 2 years compared with the placcebo group(P=0.03), but there was no significant difference between the two groups when considering overall patients with initial stage Ⅰ-Ⅳ (P=0.08). Meta-analysis showed no significant difference in the incidence of death (odds ratio 0.99, 95% confidence interval 0.62-1.58), liver related death (1.05, 0.53-2.05), liver trans-plantation (0.87, 0.53-1.41), death and/or liver transplantation (0.92, 0.64-1.31) and liver decompensation (0.94, 0.60-1.49) between the UDCA and placebo groups. Conclusions The analysis of RCTs of UDCA versus placebo shows improvement of liver biochemistry, but not improvement of clinical symptoms and survival. UDCA may slow down liver histologic progression in the early-stage patients with PBC.

OBJECTIVE: To investigate the serum IgE with various postmortem intervals (PMI) in guinea pigs due to sudden death from anaphylactic shock and to explore the effect of refrigeration of corpse on serum IgE level and its application value in forensic medicine. METHODS: The animal death models of anaphylactic shock were established. The corpses were preserved at room temperature (20 °C ) for 6 h and then refrigerated at 4 °C. The serum was sampled at 6, 12, 24, 36 and 48 hours after death. The IgE level of serum was detected with ELISA. The control group was also established. RESULTS: The serum IgE level had significant. difference between the experimental group and the control group (P < 0.05). There was no significant difference among the experimental groups at 6, 12, 24, 36 and 48 hours post- mortem (P > 0.05). CONCLUSION If the corpses were placed in 4 °C conditions 6 hours after anaphylactic death, the serum IgE still shows a good marker within 48 h for forensic investigation.

Aim To investigate the up-regulation of miR-22 through Wnt pathway inhibits the proliferation,migration and invasion in human gastric MGC803 cells induced by diallyl disulfide(DADS).Methods The effects of proliferation,migration,and invasion of gastric cancer cells were evaluated by MTT,wound-healing and invasion assays.Online prediction software was applied to search the target gene of miR-22.Luciferase report gene assay was used to assess the target genes Wnt-1 of miR-22.The expressions of Wnt-1,β-catenin and TCF-4 were tested by qRT-PCR and Western blot,respectively.Results MTT showed that DADS and miR-22 notably decreased the proliferation compared with control group(P<0.05).Wound-healing assay showed that DADS and miR-22 could significantly inhibit the migration of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Invasion assay showed that DADS and miR-22 could markedly inhibit the invasion of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Online prediction software to search the target gene exhibited that Wnt-1 may be a target gene of miR-22. Luciferase report gene assay disclosed that Wnt-1 was identified as a direct target of miR-22. Qrt-PCR showed that the expression of Wnt-1 Mrna was respectively down-regulated by DADS and miR-22 compared withcontrol group, especially in miR-22+DADS(P<0.05). Western blot exhibited that DADS and miR-22 obviously suppressed the expressions of Wnt-1, β-catenin and TCF-4 proteins, especially in miR-22+DADS(P<0.05).Conclusion Up-regulation of miR-22 through Wnt pathway can remarkably suppress the proliferation, migration and invasion in MGC803 cells by DADS.

With new acupuncture and moxibustion as the study object, based on the basic composition of acupuncture-moxibustion theory, from 3 aspects of meridian-acupoint theory, acupuncture-moxibustion method theory and acupuncture-moxibustion treatment theory, under the background of western medicine, ZHU Lian's different opinions on theory and method of acupuncture and moxibustion were discussed. It was believed by ZHU Lian that the distribution of 14-meridians was approximately identical to that of nerves, so with modern neuroanatomy knowledge to understand the meaning of acupoint; the acupuncture function could be explained from the angle of neurophysiology. Clinical diagnosis and treatment method could be established by modern classification methods of diseases. ZHU Lian's cognition that was different from traditional theory and method of acupuncture and moxibustion was combined with updated physiology and anatomy knowledge at that time, and was involved with Pavlov's advanced nerve theory, so she firstly put forward the opinion that acupuncture therapy can't work without the involvement of cerebral cortex.

AIM:To explore the preventing effect of citalopram on neuro-cell apoptosis caused by long-term stress in CA1 and CA3 region of hippocampus.METHODS:Forty male Sprague Dawley(SD)rats were randomly divided into five groups including blank group,control group(the control group was filled the stomade by 0.9% saline)and three experimental groups(intragastric administration of citalopram hydrobromide at doses of 8 mg?kg-1?d-1,4 mg?kg-1?d-1,1 mg?kg-1?d-1,respectively).Rat stress model was made by compulsory swimming everyday for 4 weeks.Cell apoptosis in CA1 and CA3 region of hippocampus was observed by HE staining method.Apoptotic cell numbers and integral optical density in CA1 and CA3 region were tested and analyzed by terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling(TUNEL)method and Norton Internet Security BR(NIS BR)software.t-test was applied to compare apoptosis cell numbers and integral optical density.RESULTS:Control rats showed more static time and less struggling times.Conversely,static time was shorter and rats spent more time after exhaustive exercise,and more struggling times in the experimental group.Rats in control group showed more positive cells in CA1 and CA3 regions and higher integral optical density in CA3 region than those in blank group.Rats in experimental groups showed fewer positive cells in CA1 and CA3 regions.Rats in experimental group 1 and group 3 showed higher integral optical density in CA1 and CA3 regions than that in control group.CONCLUSION:Long-term stress might cause neuro-cell apoptosis in CA1 and CA3 region of hippocampus.Citalopram might have prophylactic effect on apoptosis caused by long-term stress in CA1 and CA3 region,and the prophylactic effect might not be influenced by citalopram.Our study suggests that the treatment mechanism of citalopram in neural and mental illness by long-term stress may involve in a major role by antagonizing neuronal apoptosis in both the CA1 and CA3.

Objective To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.
