Objective To evaluate the cost-effectiveness of entecavir and lamivudine in treatment of early stage acute on chronic liver failure (ACLF),and analyze the predictive factors.Methods Forty nine patients with early ACLF were enrolled.Of which,28 patients were treated with entecavir,and 21 patients were treated with lamivudine.Mortality,length of hospital stay,cost,liver function,coagulation function,and model for end-stage liver disease (MELD) score were compared between two groups.Pharmacoeconomic evaluation was taken using cost-effectiveness analysis and cost minimization analysis.Results Mortality,length of hospital stay and cost had no significant difference between two groups.Ratio of costeffectiveness in lamivudine group was higher than that in entecavir group.Cox analysis showed that primary peritonitis and MELD score at the end of the second week were the main predictive factors.Conclusions Entecavir cannot improve the survival rate of early stage ACLF compared to lamivudine,but may provide economic benefit to patients with early stage ALCF.

Objective To discuss the effectiveness of rehabilitation training after arthroscopic rotator cuff repair.Methods Seventy-four cases of arthroscopic rotator cuff repair were studied.They were randomly divided into a treatment group and a control group.Both groups received shoulder passive motion training after the operation.The treatment group also received 3-phase shoulder exercises for rehabilitation.changes in American shoulder & elbow surgeons' scores (ASES scores),University of California at Los Angeles shoulder scoring system scores (UCLASS),and visual analogue scale (VAS) scores were assessed pre-operation,and 6 months and 1,2 and 3 years later.Results There was no difference between the groups pre-operation.After the operation,significant improvements in all the outcome measurements were observed in the treatment group.Significant improvement in VAS scores was observed only in the treatment group.Shoulder pain,mobility,range of active forward flexion,strength of forward flexion and patient satisfaction all improved significantly more in the treatment group than in the control group.Conclusions Early and systematic rehabilitation training is an effective way to improve the function of the shoulder joint after arthroscopic rotator cuff repair.

This study is to offer a clinical pain-depression dyad therapy of ferulic acid, the pain-depression dyad induced by reserpine was established and the dose-effect relationship of ferulic acid on ameliorating pain-depression dyad was explored. Mice were randomly divided into control group, reserpine + vechile and reserpine + ferulic acid (5, 10, 20, 40 and 80 mg x kg(-1)) groups. The reserpine treated mice were tested with thermal hyperalgesia, mechanicial allodynia and forced swimming tests, and the SOD and NO levels of hippocampus and frontal cortex were measured. Moreover, the HPLC-ECD was used to detect the changes of central monoamines concentrations. Compared with control group, reserpine can induce a significant decrease in the nociceptive threshold and increase in the immobility time of the forced swimming test. The results suggested that reserpine significantly increased the level of nitrite in hippocampus and frontal cortex and reduced the levels of SOD, 5-HT and NE in these two brain regions. However, these indexes can be a dose-dependently reversed by ferulic acid (5, 10, 20, 40 and 80 mg x kg(-1)). Ferulic acid can reverse pain-depression dyad, especially at the dose of 80 mg x kg(-1). In addition, it can influence oxidative stress and monoamine level.

Objective To investigate the value in distinguishing benign and malignant vertebral fractures with MR diffusion-weighted imaging(DWI).Methods 31 patients with 58 vertebral fractures were underwent routine MRI scanning and echo-planar DWI(EPI/DWI).The materials were divided into benign group(n=32,20 cases),malignant group(n=18,8cases),tuberculosis group(n=8,3cases) and normal vertebral body group(n=31). Signal intensities on DWI were compared and apparent diffusion coeffient(ADC) values of normal and abnormal vertebral bodies were calculated. ADC values among the benign,malignant,tuberculosis vertebral bodies and normal ones were quantitatively analyzed and compared.Results The ADC values of benign,malingnant,tuberculosis and normal vertebral bodies were (1.44?0.41)?10 -3 mm2/s,(0.94?0.17)?10 -3 mm2/s,(0.98?0.13)?10 -3 mm2/s and(0.42?0.16)?10 -3 mm2/s ,respectively. The ADC values of the three abnormal groups were higher than normal group ( all P0.05). The sensitivity and specificity of ADC for the diagnosis of malignant lesion were 72.2% and 90.6% if the upper bound of 95% confidence interval was set as a differential level.Conclusion DWI provides an important supplement to the routine MRI in the differentiation of benign with malignant vertebral fractures.

Objective To investigate the aerosolized livability,aerosolized quantity and aerosol particle diameter,etc. of phage D29. Methods Phage D29 aerosol was produced in the aerosol test cabinet in negative pressure laboratory. TSI3321 aerodynamic particle sizer spectrometer was used for detecting the diameter of the aerosol particle. Bioaerosol particle median diameter was tested with Anderson six grade microorganism sampler.

Bioaerosol particle median diameter was 2.21 μm. The livability after aerosolization for 5,15,30,45,and 60 min were 89.78％,77.19％,48.86％,33.99％,30.12％,respectively. The aerosolized quantity of phage D29 was 232 μl/min. Conclusion The characters of the aerosolized livability,aerosolized quantity and aerosol particle diameter of phage D29 were thought to be suitable for further research into aerosol inhalation treatment of Mycobacterium tuberculosis infection in animals.

Objective To investigate the effects of proanthocyanidins on depressant-like behaviors and the structure of adrenal gland in chronic unpredictable mild stress (CUMS) rats. Methods Rats were randomly divided into 6 groups:control group, stressed group (CUMS + vehicle), three treatment groups (CUMS + proanthocyanidins 25,50,100 mg·kg-1,respectively) ,and imipramine group (CUMS + imipramine 10 mg·kg-1). Used the CUMS model in rats to investigate the effects of chronic oral administration (21 days) of proanthocyanidins and imipramine (ip) on the open-field;and forced swimming and sucrose consumption tests and the ratio of adrenal gland/body weight,and its thickness were examined by HE stain. Results Compared with control group, rats subjected to CUMS exhibited increased ratio of adrenal gland /body weight ( P < 0. 01), less sucrose consumption( P<0.01) and inhibited in the open-field test( P<0.01) as well as more despair time in the forced swimming test( P<0.01). While compared with stressed group,treatments with proanthocyanidins (25,50,100 mg·kg-1, po ,21 days) could significantly improve the activities in open-field test ((39.6±3.4) vs (49±4.5), (52.6±3.7),(54.1±1.8) ;all P<0.01) and sucrose consumption( (5.8±2.5)ml vs (8.1±3.3)ml,(8.5±4.1) ml, (9.2±2.6) ml; P < 0.05, P < 0.05, P < 0.01 respectively); Meanwhile, it could reduce the duration time in forced swimming test significantly( (103.5±10.2)s vs (83.7±8.8)s,(75.8±5.9)s,(67.2±6.5)s; all P<0.01) as well as thickness of the adrenal gland(P<0.05, P<0.01).Conclusions This study suggests that the proanthocyanidins (25,50,100 mg·kg-1) has an antidepressant-like effects in CUMS rats. The antidepressant actions of proanthocyanidins, in some degrees, may be related with the regulation of the adrenal gland's structure.
