Objective To explore the relationship between serum HBeAg、the qualification of HBV DNA and the liver pathologic change in chronic hepatitis B virus (HBV)carriers with normal liver function.Methods Two hundred and forty-four chronic hepatitis B virus carriers with normal liver function were performed pathology examination by Liver biopsy.Meanwhile liver function,HBV DNA level and serological serum markers of B-hepatitis examination were detected.Results Pathology results showed that,of all 244 cases,7 cases was cirrhosis(2.9％),143 for slight CHB (58.6％),32 for moderate CHB (13.1％) and 9 for severe CHB (3.6 ％).And 53 (21.7％)chronic hepatitis B virus carriers were the normal histology morphology.Fony-eight cases (19.7％) were in inflammation stage G≥2 and 54(22.1％) were with fibrosis stage S≥2.For cases with HBV DNA positive,The inflammation and ftbrosis stages in HBeAg negative group were more severe than that in HBeAg positive group (P ＜ 0.05).The fibrosis stages in patients with low HBV DNA level were severe than that in high HBV DNA levels (P ＜ 0.05).No significant differences were observed in the inflammation stage between subjects with high or low HBV DNA level.Conclusion Most chronic HBV carriers with normal liver function were with different degrees of liver inflammation and fibrosis.HBeAg and HBV DNA associated with liver pathological change.

Objective To study the clinical characteristics of Gitelman′s syndrome, and the differentiation of Gitelman′s syndrome from Bartter′s syndrome. Methods Clinical data of 2 patients diagnosed as Gitelman′s syndrome were retrospectively analysed. Results The symptoms of both patients appeared at adult age, their main manifestation included hypokalaemic alkalosis, hyperreninemia and juxtaglomerular apparatus hyperplasia with normal blood pressure, hypocalciuria and hypomagnesemia, then the diagnosis of Gitelman′s syndrome was established. Potassium and magnesium supplementation ameliorated one patient′s symptom. Another patient treated with indomethacin, serum potassium was recovered to normal level. Conclusion Gitelman′s syndrome and Bartter′s syndrome appear to be similar in the pathogenesis, clinical manifestation and prognosis, but still show some differences, Gitelman′s syndrome should be carefully differentiated from Bartter′s syndrome.

AIM To study the effects of Lotusine(Lot), a pure alkaloid extracted from the green seed embryo of Nelumbo nucifera Gaertn, on the action potentials(APs) in myocardium and slow inward current(Isi) in cardiac Purkinje fibers(PF). METHODS standard microelectrode and two microelectrodes voltage clamp techniques were used. RESULTS Lot 1～100 ?mol?L -1 could concentration dependently prolonged APD 20 and APD 90 of fast AP and increase the contractile force(Fc) in guinea pig papillary muscles. In papillary muscles pretreated with reserpine, similar results were also observed but the effect of Lot was weaker than those pretreated without reserpine. In guinea pig left atria, Lot 30 ?mol?L -1 could partly antigoniste the shortening APD effect of acetylcholine. Lot 3～100 ?mol?L -1 could enhance the action potential amplitude(APA)and maximal velocity of phase 0 depolarization ( V max ) of slow AP of papillary muscles induced by high K + (24 mmol?L -1 )and isolated sinoatral node(SAN) pacemaker cells of rabbits with dose dependent manner,But not obvousely short the sinus cycle length of SAN. Moreover, Lot increased the Isi of in canin cardiac PF with with time dependent and dose dependent manner. CONCLUSION The results suggest that Lot has effect of prolongation of APD and increase of Ca 2+ influx and these are very important in contribution to its positive inotropic effect, which may be related to inhibition of phosphodiesterase Ⅲ.

Objective To investigate risk factors and prognosis of hemorrhagic transformation(HT)in acute cerebral infarction patients treated by intravenous thrombolysis with recombinant tissue plasminogen activator(rt-PA).Methods All 128 patients with acute cerebral infarction were treated with intravenous rtPA within 6 hours from stroke onset.The clinic records and laboratory datas of pre-and post-treatment were statistically analyzed between HT group and non-HT group to find potential risk factors to HT and contributors of prognosis.Results HT occurred in 29 patients(22.66％),including 16 patients with symptomatic ICH(12.50％)and 2 patients died(6.90％ of HT).Logistic regression analysis showed that history of atrial fibrillation(OR =1.293,95％ CI 1.224-1.589,P =0.001),CT density changes with mass effect or edema(OR =2.452,95％ CI 1.132-3.309,P =0.034),diastolic blood pressure ≥ 100 mm Hg before thrombolytic therapy(1 mm Hg =0.133 kPa,OR =9.265,95％ CI 1.435-59.836,P =0.019),blood glucose ≥ 11.1 mmol/L(OR =3.037,95％ CI 0.252-57.593,P =0.047),NIHSS score ＞ 15 points (OR =8.752,95％ CI 1.035-30.285,P =0.023)and thrombolysis time ＞ 3 h(OR =98.74,95％ CI 5.067-186.120,P =0.002)are independent risk factors for HT; among these factors,baseline blood glucose(OR =3.265,95 ％ CI 0.435-59.863,P =0.045),NIHSS score(OR =10.453,95 ％ CI 5.647-38.185,P =0.003)and thrombolysis time(OR =2.541,95％ CI 1.098-51.086,P =0.017)also are prediction factors of the prognosis of HT.Conclusion Risk factors associated with HT are diastolic blood pressure before thrombolysis,glucose level,degree of neurological deficits,CT early changes,atrial fibrillation and thrombolytic time.Glucose level,neurological deficits and thrombolysis time affects the prognosis of patients.

Background and purpose:We investigated whether lfuorine-18 lfuorodeoxyglucose (18F-FDG) maximal standard uptake value (SUVmax) of the primary tumor (SUV-T), SUVmax of the regional lymph nodes (SUV-N) or the overall loco-regional lesion SUVmax (SUV-TOTAL) was related to survival of patients with stage Ⅲ non-small cell lung cancer (NSCLC) who received Cetuximab and combined definitive chemoradiotherpay. Methods:From September 2009 to July 2012, seventeen patients with unresectable stageⅢNSCLC receiving cetuximab with cisplatin/vinorelbine (NP) followed by concomitant NP and intensity-modulated radiotherapy (IMRT) at the Fudan University Shanghai Cancer Center were enrolled onto a prospectively study. All patients received positron emission tomography/computerized tomography (PET/CT) scans within 2 weeks before enrolment. Univariate analysis were used to assess the correlation between SUV-T, SUV-N, SUV-TOTAL, gender, age, histology, tumour-node-metastasis (TNM) stage, performance status (PS) as well as smoking status and survival. The factors which showed statistical signiifcance entered into multivariate Cox-regression model. Survival functions of different populations were estimated by Kaplan-Meier method and compared by Log-rank test. Results:In the univariate analysis, SUV-T, SUV-N, SUV-TOTAL, PS and smoking status were prognostic factors. The best cut-off values for SUV-T, SUV-N and SUV-TOTAL were 11, 11 and 20, respectively. Multivariate analysis revealed that SUV-TOTAL (P=0.012), SUV-T (P=0.025), and SUV-N (P=0.033) were independent predictors of survival with hazard ratio (HR) of 14.7, 11.2, and 6.2, respectively. Conclusion:Local, regional and locoregional maximal SUVs deifned by 18F-FDG PET-CT scanning may have a strong correlation with survival in this patients setting, which merits further study.
