Objective To compare the sensitivity and specificity of interferon-gamma release assay(IGRA) in the Tibetan and Han patients with pulmonary tuberculosis(TB),and to investigate its clinical application value for screening Tibetan patients with pulmonary TB.Methods Sixty-four Tibetan cases of pulmonary TB,41 Tibetan cases of non-pulmonary TB,40 Han cases of pulmonary TB and 38 Han cases of non-pulmonary-TB in our hospital from April 2013 to April 2015 were selected and performed IGRA.T cells infected by mycobacterium tuberculosis were detected by ELISA.The difference between Tibetan abd Han nationalities was compared.The clinical value of IGRAfor screening Tibetan patients with pulmonary TB was evaluated by calculating the statistical indicators.Results The sensitivity,specificity,positive predictive value and negative predictive value of IGRA for diagnosing Tibetan pulmonary TB were 90.62%(58/64),80.49%(33/41),87.88%(58/66) and 84.62%(33/39) respectively,which for diagnosing Han patients with pulmonary TB were 92.50%(37/40),84.21%(32/38),86.05%(37/43) and 91.43%(32/35) respectively.The sensitivity and specificity of IGRA for diagnosing Tibetan and Han pulmonary TB had no statistical difference(χ2=0.005,P=0.944;χ2=0.018,P=0.893).Conclusion IGRA has high value for early diagnosis of Tibetan pulmonaty TB and is conducive to screening of early pulmonary TB.

Objective To investigate the roles of theaflavins(TFs) in airway mucus hypersecretion induced by human neutrophil elastase(HNE). Methods Human lung adenocarcinoma cell A549 was stimulated by HNE for mucus hypersecretion,and TF monomers(TF1,TF2 and TF3) were used for intervention.The effects of TF monomers on viability of A549 cells were examined by MTT method.After the effective doses of TFs were determined,A549 cells were divided into 4 groups for experiment.In control group,A549 cells were cultured with serum-free medium.In HNE treatment group,A549 cells were treated with HNE(50 nmol/L) for 24 h.In TF monomer intervention groups,A549 cells were pre-treated with TF1,TF2 or TF3(50,100 or 200 ?g/mL) for 24 h,and were then treated with HNE for another 24 h.In AG1478 intervention group,A549 cells were pre-treated with AG1478(5 ?mol/L),an epidermal growth factor receptor blocker for 30 min,and were then treated with HNE for another 24 h.The changes in mucin(MUC) after treatment by different doses of TF1,TF2 and TF3,and by TF3(200 ?g/mL) for different time(12 h,24 h and 36 h) were detected.The changes in MUC5AC mRNA expression and MUC5AC protein expression were detected by RT-PCR and ELISA,respectively. Results The MUC5AC mRNA expression and protein expression in HNE treatment group were significantly higher than those in control group(P

Objective To construct the serine protease gene(sprE)mutant and to study the pathogenicity of sprE gene of Enterococcus faecalis.Methods Recombinant suicide vector pCQ001 of Enterococcus faecalis with pTX4577,was constructed.Then,created isogenic sprE-deficient mu- tant(*sprE)by allelic replacement was constructed.Moreover,the growth ability and the virulence of the mutant were compared with those of the wide type in vitro and in vivo respectively.A mouse peritonitis model and a rabbit endocarditis model were utilized in the study.Results The *sprE was selected by kanamycin and identified by polymerase chain reaction(PCR),pulsed field gel electropho- resis(PFGE)and Southern blot.The evidences showed that the sprE gene had a major role in helping bacteria to resist the elevated temperature and oxidative stress.The virulence of mutant decreased af- ter sprE gene was knocked out.Conclusions The *sprE of Enterococcus faecalis is constructed suc- cessfully,sprE gene is important in the pathogenesis of Enterococcus faecalis,which probably is a major virulence factor of Enterococcus faecali.

This study was aimed to explore clinical effect on treatment of rheumatoid arthritis (RA) of cold-dampness syndrome by the combination of Wen-Jing San-Han Tong-Luo (WJSHTL) decoction and acupuncture. A total of 88 RA patients were selected and randomly divided into the control group and the treatment group. All 44 cases in the control group were orally administrated with diclofenac sodium, sulphasalazine (SASP) and methotrexate (MTX). All 44 cases in the treatment group were treated with the combination of WJSHTL decoction and acupuncture on the ba-sis of western medication the same as the control group. Each group was treated for three months. Improvements of clinical symptoms, body signs and laboratory indexes were observed. The results showed that clinical symptoms, body signs and laboratory indexes were greatly improved in the comparison before and after treatment in both groups with statistical significance (P < 0.05). Compared to the control group, the treatment group had no statistical significance in the improvement of rest pain, swelling numbers and index, tenderness numbers and index, morning stiffness time, liver and kidney function. Compared with the control group, the treatment group had more obvious advantages in the improvement of joint function, hand grip strength, erythrocyte sedimentation rate (ESR) decreasing, C-reactive protein (CRP) and rheumatoid factor (P< 0.05). It was concluded that compared with single western medication, the combi-nation of WJSHTL decoction and acupuncture with western medication had certain advantages in the improvement of joint function of RA and management of patient's disease condition.

Pancreatoblastoma is a rare kind of malignant tumor of pancreas,which is commonly seen among children.A female child aged 5 years was admitted to the Dapiag Hospital with the chief complaint of painless abdominal mass on June 18,2010.The results of B ultrasound showed acoustic shadow of tumor calcification and an absent of normal pancreatic echo.The results of computed tomography(CT)showed that the tumor was located at the body and tail of the pancreas with a low-density and isopycnic shadow of intermixed huge block.The parenchyma of tumor showed unequal enhancement,the periphery showed lobular-like reticular enhancement,the central necrotic area showed no enhancement,and multiple metastatic foci were observed in spleen and liver under enhanced CT scan.The patient underwent resection of the body and tail of the pancreas and the spleen.Chemotherapeutics with vincristine,cyclophosphamide and doxorubicin were adopted postoperatively.After a period of 6-month follow-up,the results of CT showed that the size of tumor was decreased.

OBJECTIVETo investigate the effects of Jiangu granule containing serum (JGG-serum) on the cyclins in rat's osteoblast at G1 phase.

METHODSOsteoblasts isolated by enzymatic digestion from SD rats were cultured and intervened with JGG-serum or normal saline (as control) respectively. Cell generation cycle was detected by flow cytometry, and expressions of Cyclin D1, cyclin-dependent kinase 4 (CDK4), oncogene protein (P21) in the osteoblast were detected dynamically using immuno-cytochemical and RT-PCR technique.

RESULTSAs compared with the control, the cell generation cycle and cell proliferation were proceeding quicker in the JGG-serum (20%) intervention group; with higher protein and mRNA expressions of Cyclin D1 and CDK4, as well as much lowered expressions of P21 in nuclei of osteoblast detected at all time points (24 h, 48 h and 72 h after treatment, P < 0.05 or P < 0.01).

CONCLUSIONJGG-serum can adjust the G1 phase cyclins in osteoblast cultured in vitro, increase the mRNA and protein expressions of Cyclin D1 and CDK4, and inhibit P21 expression, so as to accelerate the proliferation of osteoblast.
