Methods: Acute viral myocarditis was induced in 24 Balb/c mice by injection of Coxsackievirus B 3m (CVB 3m ) intraperitoneally. Half of the mice were administered Astragalus Injection(10g/kg?d). Heart and blood samples were obtained from all mice on the 8th day after CVB 3m infection for histopathological study, detection of myocardial perforin expression by reverse transcription polymerase chain reacton(RT PCR) and measurement of serum CK MB level, respectively. Results: (1) Astragalus treated mice showed a significant reduction in myocardial lesion compared with that in untreated mice. (2) Myocardial perforin expression by semi quantitative RT PCR in Astragalus treated mice was much lower than that in controls(1.10?0.07 vs 1.31?0.12, P

Objective Analysis of the etiological factors and the diagnostic methods of fever of unknown origin(FUO)in order to avoid misdiagnosis and missed diagnosis.Methods One hundred and twenty-eight patients with FUO were collected from our hospital.Results A final diagnosis was established in 118(92.2%)patients by using serological methods,bacteriological methods,body fluid test,bone marrow examination,tissue biopsy and diagnositic therapy.Infection(62.5%),connective tissue diseases(16.1%),malignancies(11.0%)were found to be the common causes of the fever in these patients while infection was the main cause of FUO in our research.The major pathogens responsible for the infec tion was bacteria,followed by virus and tuberculosis.Adult Still's disease was the most common connective tissue diseases in these patients.Lymphoma,malignant histocytosis and leukemia were the main forms of malignancy.Conclusion Infectious diseases was the most common cause of FUO while connective tissue disease and malignant tumors are also important in the pathogenesis of FUO.

Mucosal adjuvants play important roles in vaccine development. By now, the common used mucosal adjuvants can be divided into three categories: the bacterial derivatives, cytokines and chemokines, and antigen delivery systems. Progresses of the three kinds of adjuvants were reviewed to give a reference to novel vaccine research.

Objective To observe the effects of chronic arsenic exposure on estrogen receptor-binding fragment-associated gene 9 (Ebag9) and estrogen-responsive finger protein (efp) mRNA expression in female rat' s myocardium.Methods Fifty female Wistar rats were randomly divided into five groups according to arsenic (As2O3) concentrations in drinking-water:0.00(control),0.05,0.10,0.20,0.40 mg/L groups and RT-PCR was used to detect Ebag9 and efp mRNA expression of myocardium at the 32 weeks of experiment.Results Ebag9 and efp mRNA expression levels in 0.00,0.05,0.10,0.20,0.40 mg/L groups were respectively as follows:0.54 ±0.14,0.52 ± 0.10,0.48 ± 0.24,0.58 ± 0.13,0.45 ± 0.19 and 0.85 ± 0.14,0.86 ± 0.12,0.87 ± 0.09,0.99 ±0.10,0.86 ± 0.19.Compared to the control group,Ebag9 mRNA level of the 0.20 mg/L group was increased,and decreased in other groups,but the difference between two groups was not significant(all P ＞ 0.05).Compared to control group,the efp mRNA level of 0.20 mg/L group increased significantly(P ＜ 0.05),and showed increased tendency in other arsenic groups,but the difference between two groups was not significant (all P ＞ 0.05).Conclusions Ebag9 and efp mRNA expression have changed in myocardium of rats exposed to chronic arsenic.Arsenic may has endocrine disruptor effect to female rat's myocardium.

OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.

METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.

RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).

CONCLUSIONBC was effective in improving blood lipid level in mild hyperlipidemia patients.

HIV-1 integrase (IN) is a key enzyme for the viral replication. The protein-protein interaction (PPI) between HIV-1 IN and a cellular cofactor lens epithelium-derived growth factor (LEDGF/p75) is a validated target for anti-HIV drug discovery. In order to build the platform for screening inhibitor against PPI between IN and LEDGF/p75, the vector containing the LEDGF/p75 protein cDNA was constructed and expressed in Escherichia coli and the function of the LEDGF/p75 protein was assayed. The LGDGF/p75 encoding gene optimized according to the preference codon usage of E. coli, was synthesized and cloned into the expression vector pGEX-4T-1 to form a recombined plasmid, then transformed into host cell E. coli BL21 (DE3). The recombined clones were identified and confirmed by BamH I/Sal I digestion and sequencing, the successfully recombined plasmid in the host cell was induced by IPTG and the condition of the expression was optimized. The expressed protein was purified by the Ni2+ affinity chromatography column and SDS-PAGE was used to analyze the molecular weight and specificity. In addition, ELISA assay was used to analyze the function of the recombinant protein. The recombinant LGDGF/p75 was soluble, and expressed highly and stably in E. coli. The protein was proved to enhance HIV-1 IN strand transfer activity in vitro by ELISA. It will be helpful to build the platform of screening inhibitors against PPI between IN and LEDGF/p75.
