Objective To investigate the role of vascular cell adhesion molecule 1 (VCAM 1) in pathogenesis of pregnancy induced hypertension (PIH) complicated by fetal growth restriction (FGR). Methods The placenta samples were collected from 30 pregnant women with PIH complicated by FGR, 28 FGR patients without PIH and 30 normal pregnant women. Immunohistochemical analysis was used to demonstrate the positive expression of VCAM 1 in placenta vascular endothelium and syncytiotrophoblast of these samples. Results In placentas of PIH complicated by FGR (80%),expression of VCAM 1 in the decidual vascular endothelium was significantly higher than those without PIH (25%) and normal placentas (15%)( P

Objective To study the relationship between matrix metalloproteinase-9 in syncytiotrophoblast and placenta pathological change of fetal growth restriction. Methods The placental samples were collected from 30 patients with FGR and 30 normal pregnant women who delivered in our hospital from January 2001 to September 2001. The tissue sections were dealt with HE stain and PAS stain and then observed by microscope to find the morphological change. 5 another samples from each group were observed by 500H model electron microscope. Immunohistochemical analysis was employed to demonstrate the positive expression of the MMP-9 in syncytiotrophoblast of FGR placenta. Results There are significantly pathological change in 22 placentas of FGR and abnormal rate is 73.33%. The count of stroma fibrosis and fibrinoid necrosis of villi(63.3%), villous vascular decrease and gore(70.0%), villous syncytial knots(43.3%), cytotrophoblasts increase(50.0%) were more significant in the placenta of FGR group than that of normal group(6.7%,10.0%,3.3%,13.3%)(P

Concurrent chemoradiation therapy is currently a recommended treatment approach for locally advanced inoperable stage ⅢA and stage ⅢB non-small cell lung cancer (NSCLC).There is no consensus on the optimal treatment regimen.It is one of these options for the consolidation chemotherapy following concurrent chemoradiation therapy.To date,there is no sufficient evidence indicating that consolidation chemotherapy following concurrent chemoradiation therapy further improves survival rates.The benefit remains to be confirmed by more clinical test.

The earliest and the most common metastasis of hepatocellular carcinoma (HCC) occur in the intrahepatic portal venous system, which indicates its worst prognosis. In 28 HCC patients with intraportal tumor thrombus, we employed 2 procedures, ie. the transcatheter hepatic arterial embolization(THAE), transcatheter superior mesenteric or splenic arterial infusion (TSAI) and portal vein embolization (PVE) in 12 cases, and THAE alone in 16 cases. In the former group, tumor size reduced more than 50% in 8 cases (partial remission PR), in particular tumor thrombus disappeared in 3 and decreased in size in 8; whereas in the latter group, PR was achieved in 3 only, without change size of the intraportal tumor thrombus in all 16 cases (P

Purpose:To evaluate the efficacy of treating malignant pleural effusion with S 311 anticancer vaccine by intrapleural injection.Methods:62 cases with malignant pleural effusion,after drainage, S 311 anticancer vaccine 0.16 mg was injected into the pleural cavity in therapy group (T),and cisplatine 40 mg/m 2 in control group (C).The treatment was repeated after a week , then the efficacy, quality of life, survival rate and toxicities was evaluated.Results:The response rate was 90.6% in T group and 60.0% in C group. There was statistical difference between the two groups ( P

Objective To evaluate the effect of mining waste water on drinking water quality and tumor mortality of villagers. Methods Analyse quality of drinking water sampled from well which only supply water to a family which the well belongs to and survey the death reasons of whole population in the polluted area and the control area. Results Mining waste water discharged by a mine contaminated the nearby river and impacted the drinking water quality of the nearby village also. Compared with the control, the concentration of lead, arsenic and mercury in drinking water of polluted area was much higher. The 5,year total mortality in polluted area and in the control was 3.09% and 1.55% respectively. Tumor mortality in polluted area was 50%, esophagus cancer mortality was 54.24%. Tumor mortality in the control area was 20% only and most tumors were liver cancer. Conclusion The adverse effect of mining waste water on drinking water quality and human health in polluted area has been seen.

Objective To explore the relationship between chronic severe hepatitis and cryptosporidium infection to provide evidences for scientific prevention and treatment of chronic severe hepatitis. Methods Fecal samples of 218 patients with chronic severe hepatitis B (CSHB) and 140 children with diarrhea were collected, and were examined for cryptosporidium oocytes by using auramine-phenol staining method (AA-p) and modified acid-fast staining method (MAF), and for cryptosporidium DNA by PCR and restriction digestion analysis. The factors affecting cryptosporidium infection of patients with CSHB were preliminarily analyzed. Results The positive rates of cryptosporidium infection detected by AA-p, MAF and PCR in the patients with CSHB and children with diarrhea were 4.1%, 3.2%, 6.0% and 0.7%, 0.7%, 1.4%, respectively. The positive rate of cryptosporidium infection detected by PCR in patients with CSHB was higher than that in children with diarrhea (P

Objectives To understand the vaccination situation of left-behind children in rural areas,provide the evidence for developing vaccination strategies for left-behind children.Methods The counties with population over 1,000,000 were selected from Anhui and Sichuan provinces respectively to conduct survery to the children who were born between the year 2003 and 2006,and had registration on vaccination book(card).Results The proportion of left-behind and outflow children are 17.94% and 6.05% respectively.The information about the children’s parents going out most came from village doctors. The proportion of the parents going out after children born was 51.60%,staying outside for more than 10 months was 78.50%. 67.97% pareets came back home during the spring festival,35.43% left-behind children went out with their parents.Conclusion Although the number of outflow children was smaller than the left-behind children,it was easy to develop immunization gap. It is the difficult part of management on EPI to migraut children. The information aboat the children’s parents going out mostly came from village doctors. It is impotant to mobilize the enthusiasm of doctors.It is especially essential that we should propagandize to the people with vaccination knowledge to the pareets came back home during spring festival.
