Objective To construct human eukaryotic expression system expressing T cell surface molecule CD40L and identify the expression product in SCCL cell line h446. Methods The expression vector pcDNA3.1-CD40L was constructed by recombinant DNA technology, then transfected into h446 cell line of SCCL by lipidosome methods, and the expressed membrane protein was identified by flow cytometry. Results The pcDNA3.1(+)-CD40L was constructed successfully and the coding region was inserted into the vector correctly. The membrane protein was observed by flow cytometry on transfected h446 cell line of SCCL. Conclusion Human CD40L was expressed successfully in eukaryotic system, which is very important in the anti-tumor vaccination study with a recombinant human CD40L in clinic.

Objective To investigate nurses′ learning motivation and learning satisfaction with continued education and analyze its influencing factors. Method One hundred and seventy-nine nurses were enrolled in the survey and the general information questionnaire, education participation scale and continuing education learning satisfaction scale were used in the investigation. Results The average score by nursing education participation scale was (3.26 ± 0.59), and that of continuing education learning satisfaction scale was (2.74 ± 0.48). There were statistically significant differences in age, length of employment, professional title, marital status, employment mode between the scores by the two scales (P < 0.01). Conclusions Nurses′ learning motivation and learning satisfaction with continuing education are in the medium level. Pertinent guidance such as bringing continuing education in depth and width is suggested to improve satisfaction and motivations of nurses.

Objective To investigate the relationship between adiponectin /leptin ratio and metabolic index in type 2 diabetes mellitus .Methods A total of 167 cases of type 2 diabetes in our hospital endocrinology clinic 59 people from January 2013 to 2014 were enrolled in the study ,all patients were divided into three groups accordius to fasting plasma glucose(FPG)(42 people< 7 .2 mmol/L as Group 1 of ,7 .2-9 .4 mmol/L as group 2 66 people> 9 .4mmol/L as Group 3) .Patients who have been excluded from treatment with insulin or insulin .Requiring patients to 10 - 12 hours of fasting ,taken fasting blood samples and samples will be sent to the hospital clinical laboratory measured by biochemical analysis way ,the patient of glycosylated hemoglobin ,fasting blood glucose ,blood lipid indexes for comprehensive testing and calculation of patient related indexes ,and carries on the analysis .Results the patient′s body mass index(BMI) ,fasting insulin (FINS) ,low‐density lipoprotein cholesterol(LDL) ,triglyceride(TG) ,leptin and adiponectin ,between the ages of no statistical significance exists ,male patients with adiponectin levels and TG ,BMI ,HDL and LDL has a relatively close relationship (positive ,P=0 .000 3) leptin levels and BMI was negatively correlated (P<0 .05) .The adi‐ponectin levels of female patients were closely related to TG ,LDL and HD (positive correlation ,P<0 .05) .Leptin levels and TG were associated with BMI (negative correlation) ,and A/L ratio was correlated with all the indexes (negative correlation) in male and female patients (P<0 .05) .Conclusion HOMA‐IR can not be used as an important indicator of insulin resistance ..A/L and it are more suitable for .

Objective To establish a standard anti-viral treatment for chronic HBV carriers. Methods With reference to the domestic and abroad literatures, the diagnostic and therapeutic standards were set and prepared to be verified. ResultsThe diagnostic standards included:(①ALT 30 -40 IU/L: add 2 scores. (②Age:30 -39 ,add 1 score; ≥40,add 2 scores. (③Ultrasound examination: obviously abnormal,add 1 score;deteriorated during follow up:add 2 scores. ④Fibrosis markers positive: add 1 score. (⑤History of HCC in vertical relatives:add 1 score. ⑥ Existence of conditions which can induced elevation of ALT such as fatty liver or alcoholic liver or BMI ＞ 23 kg/m2,minus 2 scores. The therapeutic standards included:(①≥5 scores: should be treated;(②3 -4 scores: may be treated or just follow up;(③≤2 scores;follow up and reexamine every 6 months. ConclusionsThe above standards are preliminary suggestions which should be checked and rectified by liver biopsy to achieve a more accurate and more practical standard.

In order to investigate the role of Twist gene in the metastasis of hepatocellular carcinoma (HCC), total RNA was respectively extracted from three HCC cell strains with different metastatic potentials, HepG2, MHCC-97L and MHCC-97H. The first strand cDNA was synthesized by reverse transcription, which was then used as template to perform fluorescent quantitative polymerase chain reaction (FQ-PCR). The quantity of Twist gene expression was normalized by that of the housekeeping gene, GAPDH for each sample. ANOVA was used to estimate the relationship between Twist gene and metastasis potential of HCC. The results showed that the normalized initial cDNA concentrations of Twist gene in HepG2, MHCC-97L and MHCC-97H were (9.45+/-0.25)x10(-4), (1.82+/-0.41)x10(-3), (3.06+/-0.62)x10(-3), respectively. FQ-PCR revealed significant differences in the expression level of Twist among HCC cell strains with different metastatic potentials. It was concluded that high expression level of Twist was closely associated with more aggressive behaviors of HCC. Twist provides a novel indicator for HCC metastasis.

OBJECTIVE: To prepare rifampicin suppositories and to determine its dissolution in vitro. METHODS: Rifampicin suppositories were prepared with gelatin and glycerine as base material, the dissolution of rifampicin suppositories was determined by UV spectrophotometry and which were compared with rifampicin capsules sold in the market. RESULTS: The linear range of rifampicin was 10.0～60.0?g?mL-1(r=0.9 999), and the average recovery was 99.87%(RSD=0.42%, n=6). The dissolutions of rifampicin suppositories and rifampicin capsules in vitro at 45min were(89.9?0.97)% and(79.8?1.14)%, respectively. CONCLUSION: Rifampicin suppositories were simple in preparative method, well-formed, low in cost, and with high dissolution in vitro.

objective To evaluate the relationship between the pulse pressure and the cardiac geometric structure in patients with essential hypertension. Methods Three hundred and ninety-five patients,age ranging from 20 to 77 years,were enrolled into the study. Their clinical systolic and diastolic blood pressure (SBP/DBP) were all above 140/90mmHg. All the patients either were initially diagnosed as having essential hypertension,or confirmed after taking a the placebo for 2 weeks after stopping anti-hypertensive drugs. The cardiac geometric structure was determined by the echocardiography at the same time when the patients untook the 24 hours ambulatory blood pressure monitoring. Results The clinical pulse pressure was significantly different among the groups as divided by the age ( P

Objective To explore the feasibility of gallbladder mucosal ablation by hysteroscopic rollerball electrocoagulation after cholecystostomy.Methods Under epidural or general anesthesia combined with local anesthesia,20 patients were examined and treated with hysteroscopy after cholecystostomy.After inserting a Storz endoscope,the epithelium of the proximal cystic duct and the mucosa of the gallbladder were ablated with the roller-ball and roller-barrel electrodes respectively.The electrocoagulation power was set at 60-70 W with the roller-barrel excursion rate between 10-15 mm/s,which makes the inner wall of the cyst homogenously brown-grey.Results The mean endoscopic operation time was 35 minutes(range: 25-55).Among the patients,the gallbladder lumen was completely obliterated within one month in 12 patients,and within 3 months in 5;3 patients developed retention cysts.Conclusion Endoscopic electrocoagulation of the cholecystic mucosa is feasible for obliteration of the gallbladder.
