It's a hard but imperative research subject for postgraduate to study medical English in TCM colleges.For more than 3 years,Nanjing University of TCM has obtained good effect in such a field and their practices include adopting original edition of textbooks,selecting medical professionals who are good at English as teachers rather than English teachers who have some medical knowledge.Our teaching methodology is continuous,large volume fast reading.

Purpose:To study the roles of cyclin D1 and cyclin E in non small cell lung cancer(NSCLC) and the relationship between cyclin D1 and cyclin E.Methods:The expression of cyclin D1 and cyclin E in 87 NSCLC were studied immunohistochemically, PCNA was detected immunohistochemically to estimate the proliferative index(PI), the relationship between cyclin D1, cyclin E, PI, clinicopathological and prognostic factors were analysed.Results:Of the 87 NSCLC, 44 8%(39/87) were positive for cyclin D1 and 48.3%(42/87) for cyclin E, the PI of the cyclin D1 positive group was significantly higher than the cyclin D1 negative group( P 〈0.05).Significant differences were shown in the diameter of tumor, lymph node metastasis rate and survival rate between the positive and negative group of cyclin D1( P 〈0.01,0.05,0.01), and there were significant differences in lymph node metastasis, stages and survival rate between the positive and negative group of cyclin E( P 〈0.05,0.05,0.01). The expression of cyclin E in the cyclin D1 positive group was significantly higher than that of the cyclin D1 negative group( P 〈0.05), and the PI, diameter of tumor, lymph node metastasis rate in the coexpression group of cyclin D1 and cyclin E were significantly higher than that of the non coexpression group( P 〈0.05), while the coexpression group had significantly lower survival rate than that of the non coexpression group( P 〈0.05).Conclusions:Cyclin D1 and cyclin E are involved in NSCLC, but their effects are different: cyclin D1 is an important factor in the regulation of proliferation, cyclin E is related to the progression of NSCLC, cyclin D1 can promote the expression of cyclin E, while cyclin E can perhaps intensify the effect of cyclin D1, thus there could exist synergism between cyclin D1 and cyclin E.

Objective To study the relationship between the level of serum epithelial fatty acid binding protein (E-FABP) and cardiovascular disease in obese children. Methods Thirty children with metabolic syndrome (MS), 32 obesity children with no MS and 50 healthy children were recruited. Serum E-FABP and glucose/lipid metabolic indices were measured. Results Com-pared with the healthy children, levels of serum E-FABP in MS children were signiifcantly elevated (P=0.001). Compared with obesity children, levels of serum E-FABP of MS children were elevated, but the difference was not signiifcant (P>0.05). The cor-relations of E-FABP with waist to hip ratio, waist-to-height ratio, atherogenic index, fasting insulin, insulin resistance index were positive (P<0.05). According to the multivariate stepwise regression analysis, E-FABP was the independent risk of atherogenic index (P=0.018). Conclusions E-FABP plays a role in the development of atherosclerosis in obesity and MS.

Objective To investigate the predictive value of plasma cystatin C (CysC) in patients with acute coronary syndrome (ACS) after pereutaneous coronary intervention (PCI).Methods A total of 660 patients with ACS admitted to cardiovascular department were enrolled in this study from January 2009 to June 2010.The enrollment criteria were:(1) the stenosis degree was above 75％ in at least one coronary artery checked by coronary angiography and successful PCI; (2) normal renal function or mild dysfunction with glomerular filtration rate (GFR) ＞ 60 ml/ ( min · 1.73 m2 ).Exclusion criteria were severe liver and renal insufficiency,malignancies and valvular heart diseases.The plasma CysC levels were examined by the latex enhanced immune turbidity method within 24 hours after admission.The relevant clinical data were recorded.The patients were followed up by out-patient interview or telephone from March to June 2011 and adverse cardiovascular events were recorded.The patients were divided into four groups according to CysC level:Q1 (CysC＜1.02 mg/L),Q2 (1.02 mg/L≤＜CysC ＜1.17 mg/ L),Q3 (1.17 mg/L ≤ CysC ＜1.35 mg/L) and Q4 (CysC ≥ 1.35 mg/L).Univariate and multivariate Cox hazards regressions were established to analyze the factors related to prognosis.The proportion differences between four groups were tested by x2.The survival ratio was estimated using the Kaplan-Meier method.Statistical significance was established at a P value of less than 0.05.Results ① A total of 606 ( 91.7％ ) patients successfully accepted follow-up.Mean follow-up time was ( 14.3 + 1.7 ) months.Of them,95 patients were subjected to adverse cardiovascular events ( 15.7％ ).②The incidences of adverse cardiovascular events in Q2,Q3,Q4 were significantly higher than those in Q1 ( P ＜ 0.001 ).The rates of mortality,nonfatal myocardial infarction and target lesion revascularization in Q4 were higher than those in Q1 ( P ＜ 0.05 ).The incidences of heart failure in Q3 and Q4 were higher than that in Q1 ( P ＜ 0.05 ).③Univariate analysis demonstrated that CysC,creatinine,LVEF,age,history of PCI and NYHA grade ≥3 were the risk factors of poor prognosis (P ＜ 0.05 ).④ Multivarite cox hazards regression revealed that the elevation of CysC level remained an independent predictor of adverse cardiovascular events.The relative risk of Q3 and Q4 were 3.930 (95％ CI 1.306-11.829,P =0.015 ) and 6.380 (95％ CI 2.171-18.751,P =0.001 ) compared with Q1.⑤　The cumulative rates of survival without adverse cardiovascular events in Q2,Q3 and Q4 decreased compared with Q1 (P ＜ 0.001 ).Conclusions High plasma CysC concentration is an independent predictor of adverse cardiovascular events in patients with ACS after PCI.

We studied the effects of simulated microgravity on mouse oocytes maturation, and analyzed whether the tail-suspended model can be applied to investigate simulated microgravity effects on reproductive processes in female mice. Mouse oocytes were cultured in vitro with microgravity simulated by a rotating wall vessel bioreactor and by tail-suspended model, and the maturation rate of the mouse oocytes in the two models were examined in vivo. The maturation rate of mouse oocytes cultured in simulated microgravity was 8.93%, and that was 72.33% in 1g gravity. In ratio, oocyte maturation rate had no significant difference between the rotational group and control group. Microgravity simulated by the tail-suspended model inhibited mouse oocytes maturation and increased the rate of oocytes abnormity. The maturation rate of tail-suspended mouse oocytes was 14.54%, which was significantly lower than that of control group. Tail-suspended model should be an ideal model to investigate simulated microgravity effects on reproductive processes of female mice.

Objective To investigate the predictive value of metabolic syndrome in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).Methods A total of 660 patients with ACS admited to cardiovascular department,first affiliated hospital of zhengzhou university were enrolled in this study from January 2009 to June 2010.The enrollment criteria were:the stenosis degree were above 75％ in at least one coronary artery by coronary angiography and successful PCI procedure.Exculsion criteria were:liver and renal insufficiency,malignancies and valvular heart diseases.The relevant clinical data and labtory examination were recorded after admission. The patients were followed up by outpatients interview or telephone from March to June 2011 and adverse cardiovascular events were recorded.The patients were divided into MS and non-MS groups,and basic clinical data were compared between two groups.The proportion difference between two groups were tested by chi square. Multivariate logistic regression was established to analyze the factors related to progonosis.The survival ratio was estimated using the Kaplan-Meier method.Statistical significance was established at a P value of less than 0.05.Results ①A total of 606 (91.7％) patients successfully accepted follow-up.Mean follow-up time were ( 14.3 ±1.7 ) months.95 patients experienced adverse cardiovascular events ( 15.7％ ).②There were 393 patients (64.96％ ) satisfied the definition of metabolic syndrome.The patients in MS group were with higher BMI,SBP,DBP,blood glucose and disordered lipid (all P ＜ 0.05 ),with less fale patients (P =0.016),less current somking (P =0.008 ) and with higher platelet (P =0.037 ). The incidence of adverse cardiovascular events in two groups were 17.81％ and 11.79％ ( P ＞ 0.05 ). ③ Multivarite logistic regression revealed that the predictors of adverse cardiovascular events were age [ OR =2.628,95％ confidence interval (CI) 1.395 ～ 4.954,P =0.003 ],New York Heart Association (NYHA) ≥ 3 grade ( OR =2.310,95％ CI 1.095 ～4.870,P =0.028) and left ventricular ejection fraction (LVEF) ( OR =4.328,95％ CI 1.955 ～9.580,P ＜ 0.001 ).However,MS was not related with prognosis ( OR =1.170,95％ CI 0.583 ～ 2.345,P =0.659 ).④The cumulative survival rates of no adverse cardiovascular events in the two groups were no significant difference ( P ＞ 0.05 ).Conclusions MS is a risk factor with coronary heart disease.Howerer,it has no relationship with adverse cardiovascular events in patients with ACS after PCI.

Objective To investigate the discriminator value of Han Chinese first morning urine albumin creatinine ratio (ACR) for determining the microalbuminuria. Methods A total of 1056 participants (494 males and 562 females) were selected from epidemiologic study of the metabolic syndrome and chronic kidney disease in Pinggu district, Beijing. Eight-hour overnight urinary albumin excretion (UAE) was regarded as the gold standard for defining the albuminuria,and the ROC curve analysis was used to determine the ACR discriminator value for microalbuminuria. Results (1)Microalbuminuria was found in 12.5% of participants,macroalbuminuria in 1.7%. (2)The ACR discriminator value for microalbuminuria by ROC curve analysis was 1.95 g/mol (sensitivity 97.6% and specitivity 88.6%) for men, 3.62 g/mol(sensitivity 83.8% and specitivity 89.1%) for women, 2.78 g/mol (sensitivity 88.7% and specitivity 85.9%)for overall. The upper boundary of microalbuminuria by ROC curve analysis was 22.59 g/mol (sensitivity 100.0% and specitivity 98.8%) . (3)The inter-rater agreement of the result in this study showed that sensitivity was 91.3% and specitivity was 88.2%, positive likelihood ratio was 7.56 and negative likelihood ratio was 0.10, positive predictive value was 56.9% and negative predictive value was 98.4%. Conclusions The ACR discriminator value for determining microalbuminuria is obviously higher in women than that in men, and is higher than recommendation of international guidelines. The result by ROC curve analysis has better sensitivity and specitivity.
