Objective To investigate the association between apolipoprotein E (apoE) genotype polymorphism and cerebral palsy (CP) in Han Chinese children. Methods Two hundred and forty Han Chinese children were selected, including 120 children with cerebral palsy (CP group) and 120 normal children (control group).Polymerase chain reaction-restricted fragment length polymorphism analysis was used to determine the genotype and alleles of apoE genotype in the two groups. Results The genotype distributions of apoE in the two groups were consistent with the existence of a Hardy-Weinberg equilibrium. There were significant differences in the distributions of allelic frequency and apoE genotype between the two groups. Carrying the ε4 allele was related to cerebral palsy, and the overall risk for cerebral palsy was elevated about 5.5-fold among children carrying the ε4 allele.Conclusions There is an association between apoE genotype and cerebral palsy, and apoE's ε4 allele is the associated risk factor.

Polyamine biosynthesis is controlled primarily by ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase(AdoMetDC). Antisense ODC and AdoMetDC sequences were cloned into an adenoviral vector (Ad-ODC-AdoMetDCas). To evaluated the effect of recombinant adenovirus Ad-ODC-AdoMetDCas which can simultaneously express both antisense ornithine decarboxylase (ODC) and sadenosylmethionine decarboxylase (AdoMetDC), the human lung cancer cell line A-549, was infected with Ad-ODC-AdoMetDCas as well as with control vector. Viable cell counting, determination of polyamine concentrations, cell apoptosis,and Matrigel invasion assays were performed in order to assess properties of tumor growth and invasiveness. Furthermore,Ad-ODC-AdoMetDCas's anti-tumor effect was also evaluated in vivo in a nude mice xenograft model. It was demonstrated that adenovirus-mediated ODC and AdoMetDC antisense expression could inhibit tumor cell growth, lead to cell apoptosis and reduce tumor cell invasiveness. Polyamine levels were significantly decreased in Ad-ODC-AdoMetDCas-treated cells compared with controls.This adenovirus also induced tumor regression in established tumors in nude mice. It was suggested that as a new anticancer reagent,the recombinant adenovirus Ad-ODC-AdoMetDCas holds promising hope for the therapy of lung cancers.

Objective To observe and study the therapeutic effect of ctreotide combined with omeprazole in the treatment of liver cirrhosis with upper gastrointestinal bleeding.Methods 76 cases of patients with upper gastrointestinal bleeding caused by liver cirrhosis were selected in our hospital from January 2013 to December 2014 to be separated into the observation group and control group randomly, with each group having 38 patients.Patients in two groups were all given symptomatic treatment first.Patients in control group were given 0.1 mg octreotide dissolved 20 mL 0.9% sodium chloride solution by intravenous injection in the first administration.And the rest octreotide was given by intravenous drip at the speed of 25μg/h.The treatment lasted for 72 h.On the base of control group, patients in observation group were given 40 mg omeprazole dissolved 100 mL 0.9%sodium chloride solution additionally, twice daily, for 3 d.Then the therapeutic effect, hemostatic time, blood transfusion, rebleeding rate and adverse reactions of patients in two groups were observed.Results The total effective rate of observation group 89.47%was much more than control group 63.16% (P<0.05).And the apparent rate of observation group 55.26%was also more than control group 31.58% ( P <0.05 ) .Both the hemostatic time and blood transfusion of observation group is less than control group ( P <0.05 ) .Besides, the rebleeding rate of observation group 5.26% is much less than control group 21.05% ( P<0.05 ) ., Incidence rates of adverse reactions in two groups were 10.53% and 7.89%, with no statistically significant difference. Conclusions Treatment of octreotide combined with omeprazole on patients with upper gastrointestinal bleeding caused by liver cirrhosis can improve the therapeutic effect, shorten the hemostatic time and decrease the blood transfusion with low rebleeding rate and few adverse reaction.

Objectives The purpose of this study is to observe the effects of valsartan on hepapetic fibrosis. Methods Thirty male Sprague-Dawley rats were randomly divided into three groups: valsartan -prevetive group (A), modle group of hepatic fibrosis (B)and valsar-tan-treating group (C). The model of hepatic fibrosis in rats was induced by intraperitoneai injection of dimethylnitrosamine (DMN) for 4 weeks(2ml/kg everyday, three times a week). Valsartan (10mg/kg everyday) was given together with injection of DMN per intrngastric (Ig) in group A for 8 weeks. After stop injection of DMN, the S valsartan(10mg/kg, everyday)was given per Ig in group C for 4 weeks. After modeling, normal saline were given per Ig everyday in group B. At the end of eighth week, the histomorphylogic structure of the liver was ob-served with light microscope. Immunohistoebemical staining was used to evaluate the expression of a-SMA. Results In group B, there was a large necrotic area and a number of pesudolobes appeared in the liver tissue. In group A, there were normal hepatic cords. In the group C, there was fibrosis interval formation and portal area expansion and fibrotie intervals extending to the lobule. The quantitative analysis of Mas-son staining showed that the collagen quantities in group B was higher than that of other group(P<0.01). The collagen quantities in group A was lower than that of group C(P<0.05). The results of immanohistochemical staining showed that the expression of a-SMA in group B was strong positive, middle positive in group C, and weak positive in group A (P<0.05). Conclusion The valsartan has preventive and treatment effects on hepatic fibrosis in rats of hepatic fibrosis model induced by DMN, and the preventive effect of valsartan is better than its treatment effect. The valsartan can ameliorate the hver cirrhosis by partly suppressing the activation of HSC.

Objective To evaluate the alteration of left atrium function during left ventricular geometric remodeling in essential hypertension (EH) with real-time triplane strain rate imaging. Methods Totally 92 patients with EH and 50 healthy volunteers were enrolled. Base on Ganau, patients with EH were divided into 4 groups:normal geometry (A), concentric remodeling (B), concentric hypertrophy (C) and eccentric hypertrophy (D). Systolic peak strain rate (S_(SR)), early diastolic peak strain rate (D_(SR)) and atrium diastolic peak strain rate (A_(SR)) were measured at left atrium walls. Results Compared with normal group, S_(SR) and D_(SR) decreased in group A, B, C and D (P<0.01), A_(SR) increased in group A, B and C (P<0.01), then decreased in group D (P<0.01). Conclusion Left atrium function has changed before LV geometry changes in patients with EH. Real-time triplane strain rate imaging can assess left atrium function and its alteration correctly during left ventricular geometric remodeling in patients with EH.
