Objective To investigate the expression and clinical significance of platelet autoantibodies in children with persistent/chronic immune thrombocytopenia (pITP/cITP).Methods Total of 34 children diagnosed with pITP/cITP(14 cases and 20 cases,respectively)in the Department of Hematology and Oncology,Shanghai Children's Hospital from December 2013 to August 2014 were enrolled as the study group,including 20 male and 14 female,the median age of 5 years old.The study also included 20 healthy children (the healthy control group) matched with gender and age,and 24 cases of newly diagnosed ITP (newly diagnosed ITP group) serving as the control groups.Platelet-associated immunoglobulin (PAIg) and platelet-specific autoantibodies on surface of platelets were mea-sured by flow cytometry or flow cytometric bead.Results Significant elevation of PAIgA,PAIgM,PAIgD and specific autoantibodies against glucoprotein(GP) Ⅲa,and GP Ⅱb were demonstrated in children with cITP,as well as specific autoantibodies against GP Ⅰ b,GP Ⅲ a,GP Ⅱ b,and granule membrane protein 140 (GMP140) in children with pITP,compared with the healthy control group(P ＜ 0.05);the levels of GPⅨ,GP Ⅲ a,GMP140 in cITP group and GP Ⅱ b in pITP showed significant declination,compared with the newly diagnosed ITP group(P ＜ 0.05);between piTP group and cITP group,autoantibodies GPⅨ,GP Ⅰ b,GP Ⅱ b,and GMP140 in the latter were much lower(P ＜ 0.05).Significant negative relation between PAIgM and platelet count was found in cITP group (P ＜ 0.05).Receiver operating characte-ristic (ROC) curve analysis showed that the area under ROC curve (AUC) of GP Ⅲ a autoantibodies was larger than that of other platelet-autoantibodies in pITP/ciTP diagnosis.Conclusions Platelet autoantibodies play a significant role in pITP/ciTP,especially platelet-specific autoantibodies,which show a declining tendency in the course and may be the main mechanism.The detection of GPⅢa specific autoantibody is more advantageous against other autoantibodies in the diagnosis of piTP/ciTP.

Objective To study the effects of anthocyanins on hepatic lipid accumulation and to explore the possible mechanisms. Method HepG2 cells were treated with 1,10 and 100 ?mol/L cyanidin-3-0-?-glucoside (Cy-3-g) for 1h,carnitine palmitoyl transferase-I (CPT-I) protein level and acetyl CoA carboxylase (ACC) phosphorylation,triglyceride,fatty acid oxidation,the activity of AMPK,AMPK and p-AMPK protein levels were evaluated. Results Compared with the control,the treatment of HepG2 with 1,10,100 ?mol/L Cy-3-g resulted in significant decrease of intracellular triglyceride,and significant increase of CPT-I protein,and AMPK activity and phosphorylation. However,there were no differences in AMPK protein level among all groups. The treatment of 100?mol/L Cy-3-g promoted the fatty acid oxidation in HepG2. The treatment of 10,100 ?mol/L Cy-3-g significantly increased ACC phosphorylation. Conclusion Anthocyanin Cy-3-g could attenuate hepatic lipid accumulation in HepG2. The mechanism may result from the regulation of the AMPK-ACC-CPT-I signal pathway and promotion of fatty acid oxidation.

Objective To investigate the risk factors of mild renal impairment in cerebral infarction patients.Methods One hundred and fifty patients with cerebral infarction were enrolled from June 2012 to June 2013,and all patients received cranial magnetic resonance imaging at the first week.The clinical data of patients were recorded in detail,24 h microalbuminuria (mALB) was detected,renal function was assessed.According to mALB,the patients were divided into normal renal function group (105 cases) and mild renal dysfunction group (45 cases).Clinical risk factors between 2 groups were compared,and multivariate regression analysis was done.Results Age in mild renal dysfunction group was greater than that in normal renal function group [(67.04 ±9.37) years vs.(63.01 ± 11.18) years],the incidence of hypertension and multiple lacunar infarction were higher than those in normal renal function group[57.8％ (26/45) vs.33.3％ (35/105),57.8％ (26/45) vs.22.9％ (24/105)],leukoaraiosis grade was higher than that in normal renal function group,there were significant differences (P ＜ 0.05 or ＜ 0.01).Logistic regression analysis found that hypertension (OR =1.04 1,P =0.045) and leukoaraiosis (OR =2.048,P =0.000) were independent risk factors for cerebral infarction patients with mild renal impairment.Conclusions The incidence of mild renal impairment is higher in cerebral infarction patients,and is closely related to hypertension and leukoariosis.Early detection of 24 h mALB in cerebral infarction patients has important clinical significance.

A highly phytase-producing strain B.licheniformis LL8 was obtained by several mutagenesis of UV with B.licheniformis as starting strain.The new strain produced about two folds of phytase activity as compared with the starting strain. The production performance of the strain was stable. The cultivation conditions were optimized by single factor and orthogonal experiment. When the mutant B.licheniformis LL8 was cultivated at 55℃, initial pH 7.5 with the inoculation size of 10% for 30h in WBE medUm, the phytase activity was up to 2268.4U/mL.

0.05) . Time consumed for registration and waiting for consultation, average medical care cost, time consumed for dispensing prescription and average total patients' visit time except for diagnosis and treatment were significantly less in primary-care hospitals than those in secondary-care ones( P 0.05) . Conclusions Quality of medical care service process in primary and secondary-care hospitals was perceived good by the outpatients. In general, phenomena of long queues for registration, waiting for consultation, payment, getting drugs and short time for diagnosis and treatment in outpatient departments have been improved a little bit. Medical doctors in primary-care hospitals could provide medical care service as nearly the same as that in secondary-care ones, while time consumed for registration, waiting for consultation, payment and getting drugs, as well as for a total visit was much less in primary-care hospitals.

Objective The mortality rate of the children after surgical repair of congenital heart disease associated with acute renal injure has been reported to be 30％-79％.Peritoneal dialysis is the common treatment method for those patients,but the optimal time to initiate peritoneal dialysis is still controversial.The aim of this study was to investigate the clinic outcome of early peritoneal dialysis to the children following cardiac surgery.Methods We performed a retrospective chart of children following cardiac surgery from January 2008 to December 2009.The total number was 4561,62 of them were performed PD treatment.Data on the PD treatment children were collected from pre-operation to hospital discharge.Early peritoneal dialysis group was defintes as PD initiated at operation room or the interval between the end of operation to starting peritoneal dialysis less than 3hrs.the others were traditional PD group.Results The whole PD treatment rate was 1.36％,15 patients died.The mortality were 10.71％ (3/28) in early PD and 35.29％ (12/34) in conditional PD group respectively (P =0.036).2 patients were met RIFLE(risk,injury,failure,loss,and end-stage renal disease,RIFLE)classification as failure grade in early PD group while 10 patients in traditional PD group (P =0.001).After PD treatment 24hrs,the Vasoactive-Inotrope Scores and serum creatinine values were much lower in the early PD group children than those in the traditional PD group[(19.00 ±2.39) vs(37.00±5.22),P=0.002;(50.51 ±21.84) vs(130.13±76.09),P=0.001)].Conclusion This study shows that early PD can prevent the children after congenital heart surgery to develop AKI,and reduce the severity of the clinic status.Early intervention with PD is associated with low mortality.

The mainly antigenic sites for the adenovirus neutraliation are present on Loop1 and Loop2 of hexon.Majority research were focus in the human adenovirus.Little was known on infectious canine hepatitis virus (ICHV), which was also called canine adenovirus typeⅠ.Here,ICHV (the isolated strain) DNA was isolated and purified from the cultured MDCK cells.The Loop1 and Loop2 fragments were amplified by polymerase chain reaction(PCR) method,and then was connected by ligase T4.The target fragment was then connected with vector pET28a.The nucleotide sequence ecoding Loop1 and Loop2 was determined.The nucleotide sequence identity of Loop1 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 100%, 100% and 83.8%, and the nucleotide sequence identity of Loop2 region between the isolated strain and CLL, RI261 and Toronto A26/61 strains is 88.1% , 88.1% and 99.3%, and amino acid identity is 93.6%, 93.6% and 98.6%.The recombinant Loop protein was expressed in E.coli and was approximately 36kDa in size,and then was purified. Then BALB/c mice were injected subcutaneously in the back and armpit with the recombinant Loop protein.The anti-ICHV antibody titers of immunized serum was tested by indirect ELISA and the titers were up to 1:320.Western blot demonstrated that immunized sera could specifically combine with ICHV. The research laid a foundation for creating new genetic engineering products of infectious canine hepatitis virus.
