【Objective】To study the effect of light weight-bearing activity on postmenopausal osteoporosis.【Methods】36 female rats were randomly divided into 3 groups:① Sham,② Ovx (ovarietomized),③ Ovx+Im (ovarietomized and immobilized).All the group's maintained daily activity.And because of being immobilized,the right hind limbs of the third group lacked weight-bearing activity.12 weeks after ovarietomy,the BMD (bone mineral density),histomorphometry and biomechanics of the right femurs of rats were measured and analyzed.【Results】Comparing with the Sham group,the Ovx group's right femurs were manifested with the decrease of BMD,TBV (trabecular bone volume),MTT(mean trabecular thickness) and MCT(mean cortex thickness),while the increase of RS(resorption surface) and OS(osteotoid surface).Meanwhile their biomechanic nature declined.But statistically the BMD,MCT and the criteria of mechanical strength were not significant decrease.Otherwise,the Ovx+Im group's right femurs showed more apparent decrease of BMD,TBV,MTT and MCT.And the biomechanic nature was worse.Comparing with the Sham group,the BMD,MCT and the criteria of mechanical strength of the Ovx+Im group were statistically significant decreased.【Conclusion】If maintaining light weight-bearing activity,the ovarietomized rats were able to maintain relatively better bone quality.A lack of light weight-bearing activity wouldcause thedecline of bone quality.Thusthestudy suggested light weight-bearing activity was significantly effective on the prevention and treatment of postmenopausal osteoporosis.

To systematically review the incidence rate of adverse drug reaction/event by Qingkailing injection. Such databases as the PubMed, EMbase, the Cochrane library, CNKI, VIP WanFang data and CBM were searched by computer from foundation to July 30, 2015. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and cross check data. Then, Meta-analysis was performed by using the R 3.2.0 software, subgroup sensitivity analysis was performed based on age, mode of medicine, observation time and research quality. Sixty-three studies involving 9,793 patients with Qingkailing injection were included, 367 cases of adverse reactions/events were reported in total. The incidence rate of adverse reaction in skin and mucosa group was 2% [95% CI (0.02; 0.03)]; the digestive system adverse reaction was 6% [95% CI(0.05; 0.07); the injection site adverse reaction was 4% [95% CI (0.02; 0.07)]. In the digestive system as the main types of adverse reactions/events, incidence of children and adults were 4.6% [0.021 1; 0.097 7] and 6.9% [0.053 5; 0.089 8], respectively. Adverse reactions to skin and mucous membrane damage as the main performance/event type, the observation time > 7 days and ≤ 7 days incidence of 3% [0.012 9; 0.068 3] and 1.9% [0.007 8; 0.046 1], respectively. Subgroup analysis showed that different types of adverse reactions, combination in the incidence of adverse reactions/events were higher than that of single drug, the difference was statistically significant (P < 0.05). This study suggested the influence factors of adverse reactions occur, and clinical rational drug use, such as combination, age and other fators, and the influence factors vary in different populations. Therefore, clinical doctors for children and the elderly use special care was required for a clear and open spirit injection, the implementation of individualized medication.

AIM: To investigate the significance of autoantibodies against ?_1-adrenoceptors induced by hepatitis B virus in the pathogenesis of hepatitis virus myocarditis. METHODS: 30 mice were injected peritoneally with an emulsion of hepatitis B virus and complete Freund's adjuvant every three weeks. The autoantibodies were examined by ELISA, the heart and liver specimens were collected on 56 d for pathological observation and the binding of the autoantibodies to guinea pig cardiac myocytes were examined by immunofluorescence. Using the patch clamp technique, the effects of (1∶50) autoantibodies purified by octanoic acid extraction on the action potential and L type Ca~(2+) currents of guinea pig cardiac myocytes were also investigated. RESULTS: There was a good correlation between the autoantibodies and hepatitis B virus. Without pathological changes in the heart and liver specimens, 6 mice of the test group manifested bundle branch block, sinus arrest and premature ventricular beat etc, which were positive in the autoantibodies. The specific binding of the autoantibodies of the mice to guinea pig cardiac myocytes was observed. (1∶50) autoantibodies of the mice prolonged APD_(20), APD_(50), APD_(90) by 36.46%, 29.63% and 12.40%, respectively and enhanced L type Ca~(2+) currents by (49.67?16.01)%. CONCLUSIONS: Autoantibodies against ?_1-adrenoceptors of the mice induced by hepatitis B virus result in several arrhythmias, which might be mediated by the enhancement of L type Ca~(2+) currents.

Objective: To investigate the correlation between FIB-4 and the clinicopathological characteristics and prognosis of patients with hepatocellular carcinoma (HCC) after curative resection. Methods: From January 2009 to December 2012, the clinicopathological and follow-up data of 245 patients with HCC after curative resection were retrospectively studied. Their survival was calculated using the Kaplan-Meier method. The Cox proportional hazard regression model was used for the multivariate analysis. Results: According to FIB-4 index, patients were divided into two subgroups: FIB-4Ⅰ(≤3.25) and FIB-4Ⅱ(>3.25). FIB-4 could predict liver cirrhosis severity (Ishak grade, Grade 1-5 vs. Grad 6, r=0.681, P<0.001). It was associated with liver function such as:aspartate transaminase (P<0.001)、total bilirubin (P=0.009)、albumin (P=0.001) and platelet count (P<0.001) other than tumor clinicopathologic features. Both univariate and multivariate analysis showed FIB-4 could predict the prognosis of HCC patients (Overall survival: P=0.037 and 0.011; Recurrencefree survival: P=0.027 and P=0.043, respectively). Conclusion: The preoperative FIB-4 index could be used as a prognostic marker for the prognosis of HCC after curative hepatectomy.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

12 strains of H2-producing bacteria were isolated and purified from anaerobic sludge, aerobic sludge and river bottom sludge by Hungate method. A new species of high efficient hydrogen production bacterium Enterococcus sp. LG1 (registration number: EU258743 ) was studied deeply. It was showed that the Enterococcus sp. LG1 was an anaerobic and Gram-negative bacterium. Sequence analysis of this type of clones showed that it was affiliated with the genus Enterococcus and it was not reported yet in other paper at present. Meanwhile, batch tests of anaerobic fermentative hydrogen production by Enterococcus sp. LG1 were investigated by using sterilization pretreated sludge as substrate. The changes of soluble COD, protein, carbohydrate and pH value during hydrogen fermentation were monitored. It was found that only hydrogen and carbon dioxide were produced by this strain and no methane was detected during fermentation. The maximal hydrogen yield was 36.48 mL/g TCOD and the hydrogen concentration in the gas phase was 73.5%. The Enterococcus sp. LG1 was a butyrate fermentation bacteria analyzed by metabolites.
