Objective To evaluate the efficacy of lamivudine and thymosin alpha-1 combination therapy in the treatment of HBeAg-posi-tive chronic hepatitis B (CHB)by meta-analysis.Methods Randomized controlled trials (RCTs)of lamivudine and thymosin alpha-1 combination therapy in treatment of HBeAg-positive CHB (follow-up for at least 24 weeks),from January 1998 to date,were identified by searching Cochrane Library,PubMed,EMBASE,EBSCO,CNKI,Wanfang Data,and CQVIP.Lamivudine monotherapy RCTs were searched for in the same way as control tests.Efficacy was measured by odds ratio.Meta-analysis was carried out with RevMan 5 .2 soft-ware.Results Nine RCTs involving 600 patients were included,with 320 cases in the combination therapy group and 280 in the control group.At the end of follow-up,the combination therapy group had significantly higher serum ALT recovery rate,HBV -DNA negative conversion rate,HBeAg negative conversion rate,and HBeAg seroconversion rate than the control group (P<0.01 for all),with pooled odds ratios (95% confidence intervals)of 4.84 (3.28,7.16),2.09 (1.45,3.01),5.32 (3.35,8.46),and 6.22 (3.78,10.25), respectively.Conclusion Lamivudine and thymosin alpha-1 combination therapy is more likely to achieve sustained response rate than lamivudine monotherapy for HBeAg-positive CHB.More RCTs of high quality and large scale are required to verify this conclusion.

Objective To analyze the application value of digital radiography (DR) on healthy population.Methods 1449 cases of health examination on chest by DR were retrospectively studied,the physical examination results were analyzed.Results The medical examination of positive rate was 4.9％.The positive rate of women was higher than men ( x2 =11.493,P =0.001 ).the top 5 detection rate of diseases were lung old lesions,pneumonia,suspicious tumor,thickening and adhesion of pleural,senile pulmonary.Conclusion The DR examination was selected according to symptoms,medical history of participate in the examination,the check frequency was selected according to age.

The influence of ?-ionone and ergosterol on the growth and the yield of CoQ_ 10 in yeast was investigated. The results indicated that ?-ionone had the stimulative effect on the biosynthesis of CoQ_ 10 in yeast, and 28.3% increase of the CoQ_ 10 content in the cell was observed when the concentration of ?-ionone in the medium was 0.208?10~ -3 mol/L. Little ergosterol also had the same effect with ?-ionone, while 31.3% increase of the CoQ_ 10 content in the cell was observed when the concentration of ergosterol in the medium was 0.15?10~ -4 mol/L. However, the biosynthesis of CoQ_ 10 was inhibited when the concentration of ergosterol was 0.60?10~ -4 mol/L. Addition of ?-ionone and ergosterol to the medium resulted in 36.1% increase over the control. The results showed that the cell could effectively accumulate more CoQ_ 10 with the addition of ?-ionone and ergosterol to the medium.

Objective To discuss the effect of community nursing intervention on medication compliance and control rates of blood pressure in patients with essential hypertension.Methods Community nursing intervention was conducted to 73 community patients with essential hypertension. The patients' medication compliance was compared before and after intervention and their control of blood pressure was also observed. Results The difference was statistically significant in the comparison of patients' knowledge of antihypertension and the proper use of antihypertensive drugs before and after intervention. Blood pressure control rate was 80.82%.Conclusions Community nursing intervention can improve patients' medication compliance and effectively control the blood pressure of the patients.

Objective To find out effective ways of assessing doctors' scientific research performance via an index system so as to conduct objective evaluation. Methods An index system for assessing doctors' scientific research performance established with the Delphian method and the subjective assessment by experts were used to evaluate and mark doctors' scientific research performance and a comparison was then made between the two assessment methods. Results The results of the two assessment methods were basically the same , with the assessment via the index system being superior to the subjective assessment by experts.Conclusion The assessment of doctors'scientific research performance via the index system is a satisfactory way of assessment. It is also a dynamic system needing further perfection and development.

Cell DNA content in heart, liver, kidney of rats were analysed by flow cytometer at different postmortem interved. The rsults show that mean cellular DNA content is 99.5% at 6 hours, 91.3% at 12 hours, 87.1% at 18 hours, 81.3% at 24 hours, 76.7% at 30 hours, 74.3% at 36 hours, 72.3% 48 hours as compared with that at o hours The results ingicates that the quantitative determination of cell DNA in the tissues, mentioned above may provide an objective and reliable approach for the estimation of postmortem time.

Due to its exquisite sensitivity, excellent molecular specificity and reduced photobleaching, surface-enhanced Raman spectroscopy has wide potential applications in the fields of food and drug analysis, environmental monitoring and biological detection. However, SERS is only a qualitative or semi-quantitative detection technique at the present stage, and has not yet been widely recognized as a routine quantitative technique. This review discusses the pros and cons of the quantitative surface-enhanced Raman spectroscopic techniques developed so far in the literature, and looks forward to the future trend in this field.

Objective To study the relationship between osteopontin (OPN) gene expression and the development and metastasis of esophageal cancer, and explore the effect of growth inhibitory of artesunate (Art) on regulating the expression of OPN in esophageal carcinoma cells.Methods The expressions of OPN gene and protein were detected in normal esophageal tissue (24 cases), esophageal dysplasia (21 cases) and esophageal squamous cell carcinoma (ESCC) tissue (45 cases) byin situ hybridization and immunohistochemistry, and the relationships between the OPN gene and protein expressions and the pathological features were analyzed with SAS software. After intervention with different concentrations of Art (0, 30, 60, 120mol/L) on ESCC Eca109 cells for 24h, the levels of OPN expression and cell cycle were detected by flow cytometry.Results The expression levels of OPN gene and protein were significantly higher in esophageal cancer tissues than in esophageal dysplasia and normal esophageal tissue (P<0.01), and in esophageal dysplasia than in normal esophageal tissue (P<0.05). The expression levels of OPN gene and protein in esophageal cancer tissues showed no relations with patients' gender, age and the degree of tumor differentiation (P>0.05), but showed a positive correlation with lymph node metastasis and the invasion depth of esophageal cancer (P<0.05). After treatment by Art for 24h, the proliferation index of Eca109 cells and the expression of OPN protein decreased significantly (P<0.01) in a concentration dependent manner.Conclusions The abnormal high expression of OPN gene may participate in the occurrence, invasion and metastasis of esophageal cancer, so can be used as an objective index of metastasis for esophageal cancer. Art inhibits the growth of esophageal carcinoma cells by down-regulating the expression of OPN protein.
