Objective:To observe the theraputic effect and changes of glomerular extracellular matrix components(ECM) and PAI-1 and their relationships after cure with methyl-prednisone on immune complexes nephritis rats.Methods:Immune complexes nephritis rats model were induced with C-BSA.Levels of FN,LN in different treatment groups were analyzed by ELISA, level of PAI-1 in rats renal tissue was determined by color developing substrate,was theraputic effect of methyl-prednisone with 24 hours volumes of urine protein.Results:The levels of PAI-1,FN and LN of model groups were significantly higher than those of normal and control groups,and PAI-1 was significantly correlated with LN and FN,Glomerular mesangial matrix proliferated slightly and moderately;The levels of FN,LN and PAI-1 decreased signifcantly and glomerular mesangial matrix proliferation lessen differently after cure of methyl-prednisone for 1 and 2 weeks,but not reaching the level of normal groups;24 hours volumes of urine protein decrease significantly in treatment groups.Conclusion:The ECM accumulation correlate with PAI-1 increase in immune complexes rats,methyl-prednisone may affect ECM accumulation by interfering with PA/PAI-1 system to reach a treatment purpose.

Objective To explore the clinical characteristics of Henoch-Sch(o)nlein purpura complicated with acute necrotizing acute pancreatitis,in order to provide information for the diagnosis and differentiation of Henoch-Scht(o)nlein purpura complicated with acute abdominal disease.Methods There was a case present with purpura,abdominal pain,massive ascites and poor spirit in Department of Pediatrics,the First Affiliated Hospital of Zhengzhou University.The clinical manifestations and physical examination results were summarized and discussed,some pediatric specialists from nephrology department,surgery department,digestive system department were invited to discuss the case.The treatment was adjusted according to result of discussion,the final diagnosis was tracked.Results The case was firstly diagnosed with Henoch-Sch(o)nlein purpura,acute diffuse peritonitis with cause in dispute.After the discussion,the intestinal necrosis,perforation could not be excluded,acute pancreatitis required further identification.Exploratory laparotomy was received because of the changing condition after discussion.The intraoperative diagnosis was acute necrotizing pancreatitis.The patient recovered well with medical treatment.Conclusion When children with Henoch-Sch(o)nlein purpura had an acute abdominal disease,acute necrotizing pancreatitis should be considered in addition to intestinal necrosis,perforation.

Objective To train health care workers (HCWs)by method of conventional training plus survey of hand contamination status,the influence of two kinds of methods in hand hygiene compliance of HCWs was evalua-ted.Methods From November 2013 to April 2014,all HCWs in a cardiovascular internal medicine department were as trained subjects,they were divided into two groups (trial group and control group).Hand hygiene compli-ance status was investigated 1 month before training.In the first month after training,conventional training method was adopted by both groups,from the second to fifth month,conventional training plus hand contamination survey was adopted by trial group,hand hygiene compliance between two groups were compared.Results Hand hygiene compliance rates of trial group and control group was 42.63% (107/251 )and 41 .80% (102/244)respectively be-fore training,there was no significant difference(P >0.05 ).In the first and second month after training,hand hygiene compliance rate of trial group was 55.70% (132/237)and 63.11 % (154/244)respectively,control group was 56.52% (130/230)and 62.61 % (149/238)respectively,compared with pre-training,the differences were sig-nificant (both P <0.05),but the difference was not significant between two groups(P >0.05);From the third to fifth month,hand hygiene compliance rates of trial group was 60.73%(150/247),61 .44%(145/236),and 61 .22%(150/245)respectively,control group was 51 .68%(123/238),51 .02%(125/245 ),and 52.32% (124/237)respec-tively,there was significant difference between two groups(P <0.05).Conclusion Conventional training combined with survey of hand contamination status can promote hand hygiene compliance of HCWs.

Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is an autosomal recessive disease caused by SLC25A13 gene mutations, and is characterized by delayed jaundice clearance, liver dysfunction, and elevated aminoacidemia. The confirmed diagnosis depends on gene analysis. Citrin deficiency is one of the important causes of neonatal intrahepatic cholestasis in China. Recently more and more researches about NICCD were reported. The paper summarized the epidemiology, pathogenesis, clinical characteristics, and progresses in diagnosis and treatment of NICCD.

Objectives To investigate the overall prevalence of cardiovascular disease (CVD) in subjects hospitalized for chronic obstructive pulmonary disease (COPD),and explore the prevalence of the major CVD complications and trends in patients with COPD over a 10-year period.Methods Medical records in the PLA General Hospital,Beijing Union Medical College Hospital,and Beijing Hospital from 2000/01/01 to 2010/03/03 were retrospectively reviewed.A total of 4960 patients with COPD were reviewed in the study (3570 males,mean age,72.2 ± 10.5 years; 1390 females,mean age,72.0 ± 10.4 years).Results The prevalence of CVD in COPD patients was 51.7％.The three most prevalent CVDs were ischemic heart disease (28.9％),heart failure (19.6％),and arrhythmia (12.6％).During the 10-year study period,the prevalence of various CVDs in COPD patients showed a gradual increasing trend with increasing age.There was higher morbidity due to ischemic heart disease (P ＜ 0.01) in male COPD patients than in the female counterparts.However,heart failure (P ＜ 0.01)and hypertension (P ＜ 0.01) occurred less frequently in male COPD patients than in female COPD patients.Furthermore,the prevalence of ischemic heart disease decreased year by year.In addition to heart failure,various types of CVD complications in COPD patients tended to occur in younger subjects.The prevalence of all major types of CVD in women tended to increase year by year.Conclusions The prevalence of CVD in patients hospitalized for COPD in Beijing was high.Age,sex and CVD trends,as well as life style changes,should be considered when prevention and control strategies are formulated.

Objective Renal tumor and gynecological tumor invading into inferior vena cava and extending to the right cardiac cavities is quite uncommon,we report the experience of diagnosis and surgical treatment of intravenous tumor embolus extending through inferior vena cava into the right cardiac cavities.Methods From Junuary 2001 to May 2008,4 patients with intravenous tumor embolus extending through inferior vena cava into right cardiac cavity were treated in PUMC Hospital.Three cases were leiomyomatosis.Two patients' operation was performed by stages,firstly removed tumer in the right cardiac cavities using cardiopulmonary bypass under mid-hypothermia,and,postoperatively 3～4 weeks,total abdominal hysterectomy with bilateral salpingo-oophorectomy including the tumor mass was performed.The other patient's tumor was resected at one time.One case is renal clear cell carcinoma,The urologist performed abdominal nephrectomy and then cardiac surgeon resected tumor embolus using cardiopulmonary bypass under deep hypothermic total circulatory.Results The four patients were uneventful recovery,there was no death or any serious perioperative complications.Following up of 3 months to 4 years showed no tumor recurrence after the operation.Conclusion Confirmed diagnosis,the tumor embolus extending through inferior vena cava into the right cardiac cavities should be suspected among patients with renal cell carcinoma and multiple hysteromyoma are all critical for the treatment.Successful therapy for intravenous tumor embolus is dependent on totalone or two-stage surgical excision of the tumor and multi-department cooperation and combined therapy.
