A rapid thin flat gel isoelectric focusing method followed by ultrasensitive silver staining was developed for the determination of apo E phenotypes. Using this method, apo E phenotypes and allele frequencies in 63 normal individuals, 70 patients with hyperlipidemia and 11 patients with familial hypereholesterolemia (FH) in Nanjing were examined. TC, TG, HDL-C, LDL-C, VLDL-C, VLDL-TG in these cases were also measured. The relative frequency of the ?4 allele is significantly lower while the relative frequency of the ?3 allele is higher in this group than in the Caucasian group. Plasma TG, VLDL-TG, VLDL-C and VLDL-C/VLDL-TG are higher in the apo E3/2 phenotype, and lower in the apo E4/3 phenotype, wherea splasma TC, LDL-C levels are lower in the apo-E3/2 and higher in the apo E4/3 phenotype. It implies that the ?2 allele has the action of increasing TG-rich lipoprotein particles and reducing ch-rich lipoproteins in plasma, while the ?4 allele has an effect opposite to that of the ?2 allele. The highest prevalence of the ?4 allele was associated with type Ⅱb hyperlipoproteinemia (HLP), while that of the ?2 allele was associated with type Ⅲ-HLP. The frequency of ?2, ?4 are higher in FH patients as compared with normal subjects.

Objective To estimate the influence of abnormal glucose metabolism during pregnancy and family history of cardio-cerebrovascular disease and/or diabetes on umbilical C-peptide concentrations. Methods Chesed 85 pregnant women who had prenatal examination and their newborns as the subjects. Thirty-six newborns of mothers with gestational diabetes mellitus, impaired glucose tolerance or diabetes mellitus with pregnancy and 49 newborns of mothers with normal glucose tolerance were randomly chosed as the control group. All newborns were also classified according to whether their maternal grandparents had history of diabetes and/or cardio-cerebrovaacular disease. Therefore, there were four groups in this study: 25 newborns in group A were of diabetic mothers and positive family history, 11 newborns in group B were of diabetic mothers but negative family history, 9 newborns in group C were of mothers with normal glucose tolerance but positive family history, 40 newborns in group D were of mothers with normal glucose tolerance and negative family history. The blood samples of umbilical veins were collected at the time of delivery. Umbilical C-peptide levels of the four groups were measured by radioimmunonssay. Results The umbilical C-peptide concentrations of newborns in group A, B, C, D were (2.22±1.52), (1.44±0.63), (1.13± 0.34), (1.31±0.69) μg/L respectively, the umbilical C-peptide concentrations of newborns in group A were elevated compared to those of other three groups (F=5.11, P=0.003), and there were no significant differences in C-peptide levels of newborns between the three groups (group B vs C P=0.499, group B vs D P=0.694, group C vs D P=0.642). Conclusion Special attention should be given to newborns of diabetic mothers and whose maternal grandparents have history of diabetes and/or cardio-cerebrovascular disease.

Objective To evaluate the effect of detailed disease management model in community management of hyperuricemic patients.Methods One hundred and fifty patients with primary hyperuricemia were randomly divided into detailed management group and conventional group from April to June 2012,patients in two groups were managed by different models for 1 year.The weight,height,biochemical indexes including blood uric acid and serum lipids were measured and a questionnaire survey was conducted with the items of disease awareness score,smoking,drinking,diet,standard treatment,satisfaction of treatment etc.before and after management.Results One hundred and thirty six patients completed the study including 68 in detailed management group and 68 in conventional group.After one year management,the blood uric acid,triglyceride,low density lipoprotein (all P ＜ 0.01) were statistically lower than baseline in detailed management group,while there were no statistical differences of these indexes in conventional group (P ＞ 0.05).The disease awareness score increased from (65.4 ±5.4) to (82.7±4.2) (Z=-10.2,P＜ 0.01),high purine diet rate fell from 47.1％ to 7.4％ (x2 =33.6,P ＜ 0.01),the standard treatment rates increased from 10.3％ to 85.3％ (x2 =76.6,P ＜0.01),treatment satisfaction rate increased from 51.5％ to 88.2％ (x2 =21.8,P ＜0.01) in detailed management group.In detailed management group,the blood uric acid (Z =-7.4,P ＜ 0.01),total cholesterol (Z =-0.01,P ＜ 0.01),triglyceride (Z =-2.4,P ＜ 0.01) and low density lipoprotein (Z =-3.2,P =0.03) and high purine diet rate were lower (x2 =27.1,P ＜ 0.01),the standard treatment rate (x2 =70.6,P ＜ 0.01) and treatment satisfaction rate were higher (x2 =5.6,P =0.02) than those in conventional group after 1 year management.Conclusion Detailed disease management is an applicable and effective model for community management of hyperuricemic patients.

Objective:To evaluate whether Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection has posi-tive effects on the prevention and treatment of radiation-induced lung injury. The basic function and mechanism of Salviae Miltiorrhi-zae Liguspyragine Hydrochloride and Glucose Injection were also investigated. Methods:A total of 70 adult male rats weighing about 200 g were selected and divided into seven groups. These groups were as follows:1) normal control group (N):rats were injected with 1 ml of normal saline per day;2) single medicine treatment group (D):rats were administered with 1 ml of Salviae Miltiorrhizae Ligus-pyragine Hydrochloride and Glucose Injection per day;3) single irradiation group (Z):rats were exposed to 20 Gy single whole-chest ir-radiation and injected with 1 ml of normal saline per day;4) irradiation with 10 Gy and medicine treatment group (Z10):rats were ex-posed to 10 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day; 5) irradiation with 15 Gy and medicine treatment group (Z15): rats were exposed to 15 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day;6) irradiation with 20 Gy and medicine treatment group (Z20a):rats were exposed to 20 Gy single whole-chest irradiation for four weeks, and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day;and 7) irradia-tion with 20 Gy and medicine treatment group (Z20b):rats were exposed to 20 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day. Two rats were selected and sacrificed at the end of two, four, six, eight, and ten weeks of irradiation. Samples of blood and lung tissues in rats were obtained. Results:In the group with single irradiation, the tumor necrosis factor-α (TNF-α) and transforming growth factor-β (TGF-β) levels in plasma of rats were higher than those in the other groups. In the group with irradiation and medicine treatment, the TNF-αand TGF-βlevels in plasma were higher than those in the normal control group and single medicine treatment group. In the group with single irradiation for four weeks,some petechial hemorrhages on the surface of the lung were visible to the naked eye. In the groups with medicine treatment, the petechi-al hemorrhages on the surface of the lung visibly reduced. According to the pathological mechanism of lung tissues, the groups with Sal-viae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection exhibited less inflammation than the single irradiation group. Ir-radiation at 20 Gy for four weeks followed by a daily abdominal injection was slightly better than single irradiation, but the effects were not obvious. Conclusion: Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection could prevent the occurrence of lung injury by reducing the TNF-αand TGF-βlevels in plasma. After the occurrence of radiation-induced pneumonitis, the application of medicine could not decrease the symptoms.

AIM: To investigate the role of expression of peroxisome proliferator-activated receptor ?(PPAR ?) in pathogenesis of rat fatty liver.METHODS: The rats were treated with a low dose of carbon terachloride (CCl 4) and fed a high fat diet to produce fatty liver. We determined the concentrations of triglyceride (TG), total cholesterol (TC), free fatty acid (FFA) in liver and the alanine aminotransferase (ALT) activity, tumor necrosis factor-? (TNF-?), FFA in serum and the degree of hepatocytic steatosis. Total RNA of liver was extracted, and the expression of PPAR ? were analyzed by semi-quantitative RT-PCR method. RESULTS: In model group, the hepatocytic PPAR ? mRNA expression decreased to 0 41?0 28, compared to 1 41?0 29 in the control group ( P

Objective To study the relationship between graft injury and expression of redox factor-1 in early period after liver transplantation in rats. Methods One hundred and fifty adult male Wistar rats were randomly divided into three groups: liver transplant group, sham surgery group and control group. Animals were sacrificed in each group at different time points: 3,6,9, 12,24 hour after liver transplantation. The changes and significance of the expression of Ref-1 were explored by immunohistochemistry, serology and histopathology. Results Compared with sham surgery group and control group, the expression of Ref-1 protein in transplant group was higher than that in other two groups in early period after liver transplantation ( P ＜ 0. 05 ). In pathology there were lots of inflammation cells infiltration around the portal veins, and cell damage of hepatic tissue, while that in sham surgery and control group was comparatively slight. Serum ALT and AST values reached the peak at 6 ～ 12 h, and decreaced significantly after 12 h ( P ＜ 0. 05 ). Conclusions Graft injury after liver transplantation during early period reaches peak at 6 hour and then decreased. Hepatic ischemic reperfusion injury promotes Ref-1 expression, which in turn compensates for programme cell death induced by the injury.

Objective To investigate the effects of alpha-melanocyte-stimulating hormone (alpha-MSH) on the production of tumor necrosis factor-alpha (TNF-alpha) and intedeukin-10 (IL-10) by peri-pheral blood monohuclear cells (PBMCs) from patients with psoriasis vulgaris. Methods Heparinized peri-pheral blood was obtained from 20 patients with psoriasis vulgaris and 10 healthy human controls. PBMCs were isolated, cultured in complete medium, and stimulated with phytohemagglutinin (PHA) alone, the com-bination of PHA and various concentrations of alpha-MSH, or nothing. After another 48-hour culture, ELISA and real-time PCR were performed to measure the secretion levels of TNF-alpha and IL-10 in the super-natants of cultured PBMCs as well as the mRNA expression levels of TNF-alpha and IL-10 in PBMCs. Results The secretion level of TNF-alpha in the supematants of patient-derived PBMCs stimulated by nothing or PHA alone was significantly higher than that from normal control-derived PBMCs (329.87 ± 99.33 ng/L vs 116.95 ± 37.15 ng/L, 1756.01 ± 183.60 ng/L vs 1287.30 ± 152.36 ng/L, both P<0.01). alpha-MSH of all tested concentrations (10-13, 10-11, 10-7,mol/L) could inhibit the secretion of TNF-alpha by PBMCs com-pared with PHA alone (all P < 0.01), and the maximum effective concentration was 10-13 mol/L. On the con-Wary, a significant decrease was observed in the secretion level of IL-10 in the supematants of patient-derived PBMCs stimulated by nothing or PHA alone compared with normal control-derived PBMCs (P <0.05 or 0.01). Moreover, the secretion of IL-10 by PBMCs was promoted by alpha-MSH of all tested con-centrations (P < 0.01 or 0.05), with the maximum effective concentration being 10-13 mol/L (P < 0.01). The alpha-MSH of 10-13 mol/L down-regulated the mRNA expression of TNF-alpha (P < 0.001), but up-regnlated that of IL-10 (P < 0.001) in PHA-stimulated PBMCs from patients. Conclusion alpha-MSH can regulate the production of TNF-alpha and IL-10 by PHA-stimulated PBMCs from patients with psoriasis vulgaris.
