Objective To explore the effects of simvastatin in the treatment of hyperlipidemia fatty liver. Methods Animal models were set up by feeding high caloric diet. Liver index (liver weight/body weight), liver function, blood lipid, liver lipid, the content of MDA in serum and liver were assayed before and after therapy with simvastatin. Results Liver index, blood lipid, liver lipid, and the content of MDA in liver as well as in serum increased significantly ( P

Objective To investigate the prevalence of subclinical hypothyroidism and its relation to serum total cholesterol (TC),triglyceride (TG) levels and non-alcoholic fatty liver.Methods Serum levels of TC,TG, TSH,TT_3 and TT_4 were determined in 1 602 subjects which were divided into groups by sex and age (20-39,40- 59 and≥60 years).Fatty liver was diagnosed by type B ultrasonography.Restults ( 1 ) Prevalence of subclinical hypothyroidism was 6.6% in this population.(2) The mean levels of serum TC and TG in subclinical hypothyroidism group and normal group showed no significant difference ( both P＞0.05 ).(3) On the whole,the prevalences of subclinical hypothyroidism in hypercholesterolemia group and normal cholesterolemia group showed significant difference (P＜0.01 ).(4) In the three age groups of male and few.ale examinees,the prevalences of subclinical hypothyroidism in hypercholesterulemla group and normal cholesterolemia group showed no significant difference ( all P＞0.05 ).In the multiple regression analysis,TSH level was not related with raised TC level.(5) In the three age groups of male,there was no significant difference between the prevalences of subclinical hypothyroidism in hypertriglyceridemla group and normal triglyceridemia group ( all P＞0.05 ).In female,expect for the elderly group (＞60 years old ),the prevalence of subclinical hypothyroidism was higher in hypertriglyceridemia group than that in normal triglyceridemia.However,in the multiple regression analysis, increased TSH level was positively associated with increased serum TG level ( OR = 1.072,P=0.013 and OR = 1.102,P = 0.03 ).(6) The prevalence of subclinical hypothyroidism in non-alcobolic fatty liver group and normal group showed no significant difference ( P＞0.05 ).In the multiple regression analysis,TSH level was not the independent risk factor of non-alcoholic fatty liver (P＞0.05 ).Conclusion Subclinical hypothyroidism is not asseciated with serum TC level but positively associated with serum TG level.Subclinical hypothyroidism does not apparently increase the prevalence of non-alcoholic fatty liver.

Objective To investigate the effect of pidotimod granules combined with Yupingfeng granules in the treatment of children with recurrent respiratory infection.Methods A total of 124 patients in the treatment of children′s immunologic function with recurrent respiratory infection were taken into this research.124 patients were divided into OBG(63 patients)group and COG(61 patients)group according to random number table and treated with pidotimod granules and Yupingfeng granules.Statistics of children′s treatment in the two groups were collected and analyzed after research.Results In OBG group,there were 33 excellent cases,28 effective cases,2 void cases,and the treatment efficiency was 96.83%,which were better than those in COG group(χ2 =8.796,9.054,8.931,9.135, all P <0.05).In OBG group,the extinction time of fever,moist rale,expectoration and chest pain were significantly shorter than those in COG group(t =8.562,9.025,8.747,8.637,all P <0.05).The differences between the two groups after treatment in IMF were statistically significant (all P <0.05 ).Conclusion Pidotimod granules and Yupingfeng granules has perfect effect in the treatment of children′s immunologic function with recurrent respiratory infection,which is worthy of promotion.

Corynebacterium glutamicum SA001 is a mutant with lactate dehydrogenase (ldhA) deletion. In order to increase metabolic flux from isocitrate to succinate, and to improve the production of succinate under anaerobic conditions,we transducted the gene aceA coding isocitrate lyase (ICL) from Escherichia coli K12 into Corynebacterium glutamicum SA001 (SA001/pXMJ19-aceA). After 12 h aerobic induction by adding 0.8 mmol/L of IPTG, the recombinant strain was transferred to anaerobic fermentation for 16 h. Succinate reached 14.84 g/L, with a productivity of 0.83 g/(L x h). Compared to C. glutamicum SA001, the activity of ICL of the recombinant strain was increased 5.8-fold, and the succinate productivity was increased 48%. Overexpression of isocitrate lyase will increase the metabolic flux of glyoxylate bypass flowing to succinate.

Objective To observe and compare the clinical characteristics of colorectal related multiple primary carcinoma (MPC) and colorectal carcinoma (CRC) for promoting early diagnosis and treatment of colorectal related MPC. Methods Pathological and clinical documents of clearly staged CRC and colorectal related MPC cases from Jul. 1997 to Nov. 2007 were retrospectively analyzed. Results 573 colorectal carcinoma cases were analyzed, including 45 MPC (7.85 %). Parenteral multiple carcinoma originated most frequently from stomach, and then breast, ovary, lung, small intestine and other sites. Among all multiple primary colorectal carcinomas (MPCC), ascending colon carcinoma was most frequent (34.0 %).While among CRC cases, rectal cancer cases was most frequent(36.5 %). Comparing CRC and MPCC, there were no significant difference in terms of tumor family history. Median morbidity age was 57 years and 63 years respectively. Cases with previous colonic polyps accounted for 20.0 % of all MPC cases, while only 0.9 % of all CRC cases. The mOS of CRC and MPC was 93.7 month and 64.8 month respectively. Most frequent pathological type of CRC and MPC were both well-moderately differentiated adenocarcinoma, but more mucinous adenocarcinoma cases were observed in MPC. Conclusion Colorectal related MPC are relatively common among colorectal carcinoma patients. More patients with MPC especially MPCC has colonic polyp. mOS of MPC is shorter than that of CRC, indicating the poor prognosis of MPC compared with CRC.MPCC has multiple colonic polyps, shorter interval of secondary carcinomas, and shorter mOS, worse prognosis than MPC with parenteral tumor.

Objective To investigate the effects of RNA interference(RNAi)targeting human epithelial growth receptor-2(HER-2)gene on the invasive and chemotactic ability of SKOV3 cells. Methods Glyeeraldehyde-3-phosphate dehydrogenase(GAPDH)was used as the positive control. Lipofectamine 2000 mediated transient transfection was conducted to transmit the siRNA into SKOV3 cells. Three pairs of specifically targeted(HER-2 siRNA Ⅰ,HER-2 siRNA Ⅱ,HER-2 siRNA Ⅲ)sequence were selected in the coding region of HER-2 mRNA.Transfection of HER-2 siRNA was conducted with lipofeetamine 2000 in ovarian carcinoma cell line SKOV3.The HER-2 gene expression was assessed by real- time PCR and western blot assays.Changes of invasive and chemotaetie capacity of SKOV3 cells were measured by polycarbonates coated with or without matrigal.Results Western blot results showed that the expression of GAPDH protein was decreased in specifically transfected cells and with the increase of siRNA dose,the expression of GAPDH protein was decreased.GAPDH protein gray value in control group, different doses(0.5,1.0,1.5,2.0 ?g)GAPDH siRNA interference groups were 0.6855?0.0259,0.5698 ?0.0275,0.4542?0.0296,0.3341?0.0178 and 0.1816+0.0180,respectively.There was a significant difference in each group(F=198.126,P

Objective To investigate the clinical significance of anticardiolipin antibodies (ACA)in patients with hemorrhagic fever with renal syndrome(HFRS).Methods The serum ACA- IgM and ACA-IgG in 175 cases of renal diseases and 50 healthy cases were detected by enzyme-linked immunosorbent assay(ELISA). The positive rates of ACA were calculated and compared among different groups.Results The positive rates of ACA-IgM and ACA-IgG in control group were both 0 (0/50),while they were 85.2%(46/54)and 24.1%(13/54)respectively in patients with HERS. 25.0%(13/52)and 21.2%(11/52)respectively in patients with lupus nephritis and 13.0%(9/69) and 8.7%(6/69)respectively in patients with nephrotic syndrome.The poshive rate of ACA lgM in patients with HFRS was higher than that in control group,lupus nephritis group and nephritic syn- drome group(P
