Objective:To analysis the clinical characteristics of pulmonary hypertension (PH) complicating pregnancy, then to explore the delivery time and the monitodng as well as the treatment during perinatal peri-od.Methods:The data of 10 cases with PH treated in our hospital from June 2005 to January 2009 were retro-spectively analyzed.Reaults:1 case was primary pulmonary hypertension(PPH) ; 9 cases were secondary PH (SPH), in which 4 cases were rheumatic heart disease and 5 cases were congenital heart diseases.3 cases were slight PH,6 cases were moderate PH, and 1 were severe group.4 cases NYHA class were Ⅰ～Ⅱ and 6 cases NYHA class were Ⅲ～Ⅳ.4 cases were term delivery,5 cases were premature delivery, and 1 got artifi-cial abortion.8 cases were cesarean section, and 1 was vaginal delivery.2 cases were very low birth weight infants, 1 infant was death and 1 mother was death.Conclusions:The patient of PPH should avoid concei-ving.For SPH patients whether to conceive depends on cardiac function, the level of pulmonary arterial pres-sure and should better get pregnancy after surgery or medication.It should terminate pregnancy in the first tri-mester for moderate or severe patients.Cesarean section is more suitable for those in the second or third tri-mester.The prognosis of the mother and neonate depends on several factors.

BACKGROUND: The recent researches show that there are various kinds of autoantibodies in epilepsy patients such as anti-nuclear antibodies, anticardiolipin antibodies,anti-?2 glucoprotein antibodies and anti-glutamic acid decarboxylase antibodies,which indicate that some types of epilepsy are mediated by autoimmune mechanism.OBJECTIVE: To detect the level of anti-glutamic acid receptor (GluR1)antibody in epilepsy children.DESIGN: A controlled trial.SETTING: Medical College of Dalian University, General Hospital of Jilin Chemistry Group and Sanchong University, Japan.PARTICIPANTS: Totally 56 cases of epilepsy children were from Maternal and Child Health in Qingdao City including 30 males and 26 females and aged from 3 months to 13 years.While 48 health examinees and 12 patients with brain tumor from General Hospital of Jilin Chemistry Group were taken as controls, including 38 males and 12 females and aged from 6months to 17 years.Their guardians were all informed of the detection index and consented to join the study.METHODS: Polystyrene plates were coated with GluR1 polypeptide antigen,and optimal conditions of enzyme linked immunosorbent assay (ELISA) for GluRI antibody was ascertained with chessboard titration.MAIN OUTCOME MEASURES: The GluR1 antibody level was detected with ELISA.RESULTS:The concentration of coating GluR1 polypeptide antigen was20 mg/L; The dilution of serum and horseradish peroxidase sheep anti-hu-man (HRP-SaH) IgG were 1:50 and 1:1 500 respectively. Intra-assay andinter-assay coefficientof variability were 4.48％-8.80％ and 11.18％-16.60％ respectively; The specific absorption test demonstrated that the ab-sorbance value of positive serum decreased 2.4 times after absorption ofGluR1 polypeptide compared with that before absorption.There was obvi-ous higher positive rate of GluR1 antibody in serum of epilepsy childrenthan control group (40％, 5％, P＜0.01).CONCLUSION:①ELISA is specific and stable for GluR1 antibody in serum. ②There is the possible autoimmune response of GluR1 antibody in serum of epilepsy children.

Objective To study the association of the serum soluble intercellular adhesion molecule-1(SICAM-1) and soluble vascular cell adhesion molecule-1(SVCAM-1) with metabolic syndrome(MS) and its components. Methods The MS was defined by criteria of the international diabetes federation. The levels of SICAM-1 ,SVCAM-1,plasma glucose,insulin,lipids,uric acid, glycosylated haemoglobin A(1C), and blood viscosity were measured. Results The concentrations of SICAM-1 and SVCAM-1 were significantly higher in subjects with MS and its components than in those without them. The concentrations of SICAM-1 and SVCAM-1 were correlated positively with disorder number of BMI, WHR, SBP, DBP,FPG, 2 hour plasma glucose, triglyceride, uric acid, HbA1c, blood viscosity and HOMA-IR,and negatively with high density lipoprotein cholesterol. Conclusions The concentrations of SICAM-1 and SVCAM-1 rise with the increase of the number of MS components. Endothelial dysfunction might participate in the occurrence and development of MS.

Objective To investigate the effects of dieting and exercise intervention on lipid level in patients with hyperlipidemia.Methods Health education including dieting and exercise interventions was given to 1,800 patients with hyperlipidemia.Serum total cholesterol(TC), triglyceride(TG), high density lipoprotein(HDL-C)and low density lipoprotein (LDL-C)levels were assessed before and after interventions.Result TC, TG and LDL-C levels were decreased and HDL-C increased after interventions with statistical significance(P<0.01).Conclusions Dieting and exercise intervention can be effective in controlling lipid levels effectively.Health education should vary among individuals to achieve good effects.

Objective:To determine the CD 30 expression in patients with hemorrhagic fever with renal syndrome(HFRS).Methods:The double immunofluorescence technique and flow cytometry were used.Results:There is no significant difference among the three groups of HFRS patients on the CD + 4CD - 30 T lymphocyte subset.While the CD + 4CD + 30 T cells increase and the difference between severe group and mild-moderate group is very significant(P

Objective To investigate the difference of serum high sensitivity C-reactive protein(hs-CRP)concentrations in subjects with various glucose tolerances,and to analyze the correlation with insulin resistance.Methods A total of 90 subjects,who came from the Medical Examination Center of the First Hospital Affiliated to China Medical University from Oct.2004 to Apr.2005,were divided into five groups according to oral glucose tolerance test(OGTT):normal glucose tolerance(NGT)group;impaired fasting glucose(IFG)group;impaired glucose tolerance(IGT)group;IFG and IGT(IGT/IFG)group;newly diagnosed,complication-free type 2 diabetes(T2DM)group.By using the ELISA methods,the concentration of serum high sensitivity C-reactive protein(hs-CRP)was measured in these subjects,and its correlation with homeostasis model assessment insulin resistance index(HOMA-IR)was andlysed.Results The concentration of hs-CRP was significantly higher in IFG,IFG/IGT,T2DM than in NGT.The concentration of hs-CRP was positively correlated with glucose metabolism index and insulin resistance index.Conclusion Our study demonstrates that inflammation already exists not only in T2DM patients but also in subjects with IFG.Inflammation might participate in the occurance and development of T2DM.

Objective To establish an early,simple and rapid colloidal gold strip method for the detection of IgM against hantavirus nucleocapsid protein in patients with hemorrhagic fever with renal syndrome(HFRS).Methods Purified recombinant Hantavirus nucleoprotein(rNP)was labeled by colloidal gold particles and then sprayed and fixed on fiberglass membrane as the combination pad.Anti-Human IgM(μ-chain specific)antibody produced in goat was fixed in the detection area,and mouse antihantavirus antibody was fixed in the quality control area.Both of them were on nitrocellous membrane strip in tandem.Together with a specimen pad ahead.The conbination pad and the nitrocellous membrane were assembled into a test strip.The colloidal gold strip assay was compared with ELISA for evaluation of specificity and sensitivity.Results The colloidal gold strip tests showed positive in the serum samples from 50 cases of HFRS which was clinically diagnosed and then verified by ELISA within 10-15 minutes.Whereas 30 serum samples of healthy donors have tested negative.Conclusions Our new colloidal gold immunochromatographic test strip method was well concordant with the ELISA assay,but the former was more raoid and simole.It could be used primary medical services.

Purpose To analyze clinicopathologic and prognostic features in 9 cases of children endocapillary proliferative glomerulone-phritis with hepatitis B virus antigen deposition ( HBV-ECPGN) . Methods Retrospective analysis of demographic information, clini-cal manifestations, laboratory parameters, pathological and prognostic features was carried out for 9 cases of HBV-ECPGN and 13 cases of acute poststreptococcal infection endocapillary proliferative glomerulonephritis ( APS-ECPGN) for comparison. Renal biopsy tissue were fixed in formalin and embedded in paraffin, stained with HE, PAS and PAM-Masson. Immunohistochemical study with EliVision method was performed. Three cases were submitted for electron microscopy. Results There were 7 males and 2 females ( M ∶ F=7 ∶ 2) of HBV-ECPGN. The median age was 10. 3 years. Serum C4 deposition ratio HBV-ECPGN was significantly greater than APS-ECPGN group (P<0. 05). There was an average of 11. 2 weeks of HBV-ECPGN kidney disease duration, which was significantly lon-ger than an average of 3. 8 weeks of APS-ECPGN group (P<0. 05). There was no disease relapse in all cases during 53. 55 months follow-up. C4d deposit was significantly stronger in all HBV-ECPGN cases compared with control group (APS-ECPGN cases). There were no significant differences in deposit of IgG, IgM, IgA, C3d and C1q between the two groups. HBsAg deposit in juxtaglomerular sites was identified in all cases. Conclusions Serum C4 decrease is more common in HBV-ECPGN than APS-ECPGN. Which may be associated with HBV infection, there is longer disease duration of HBV-ECPGN. C4d deposit is significantly stronger than control group, suggesting pathogenesis of HBV-ECPGN and APS-ECPGN is different. HBsAg deposit may be closely related to the pathogene-sis of HBV-ECPGN. HBsAg deposit in juxtaglomerular sites may be characteristic of HBV-ECPGN.

Objective To realize the incidence of healthcare-associated infection(HAI)in patients after receiving extracorporeal membrane oxygenation(ECMO)procedure,and to evaluate the related factors for HAI.Methods Clinical data of patients receiving ECMO from January 2003 to December 2012 were collected and analyzed retro-spectively.Results Of 43 patients receiving ECMO,15 (34.88% )developed 24 times(55.81% )of HAI. The main HAI site was lower respiratory tract(n= 12,50.00% ),followed by blood stream(n= 6,25.00% ),skin and soft tis-sue(n= 5,20.83% ).A total of 28 isolates of pathogens were detected,gram-negative bacilli were 19(67.86% )iso-lates,gram-positive cocci 7(25.00% ),and fungi 2(7.14% );pathogens were mainly isolated from specimens of sputum(n= 12,42.86% ),blood (n= 9,32.14% )and wound secretion(n= 6,21 .43% ). The incidence of postopera-tive HAI in ECMO patients was related with patients’age,duration of ECMO,complication,mechanical ventila-tion,tracheal intubation or tracheotomy,and indwelling urinary catheter.Conclusion HAI in patients receiving EC-MO is high,hospital should take corresponding prevention and control measures targeting to the related risk factors of infection,so as to reduce the incidence of HAI after the ECMO.
