Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

· AIM: To explore the dynamic expression and correlation among telomerase catalytic subunit (TERT), proliferating cell nuclear antigen ( PCNA) and antiapoptosis protein Bd-2 which relate to cell proliferation in epiretinal membrane of rat traumatic proliferative vitreoretinopathy(PVR).· METHODS: S-P technique was applied for immunohistochemical staining of epiretinal membrane of traumatic PVR with TERT, PCNA and Bcl-2 antibody. HE staining was also carried out. The staining results were analyzed with image analysis system.· RESULTS: The positive rate and average A of PCNA protein were upregulated at first and then down-regulated, with the peak value in 14d Group, which was significantly different from those in 7d Group and 28d Group.The positive rate and average A of TERT and Bcl-2 were also upregulated at first and then down-regulated, with the peak value in 14d Group and 21d Group, which were significantly different from those in 7d Group. There was significant correlation among PCNA, Bcl-2 and TERT protein expression (P≤0.01).· CONCLUSTON: TERT and Bcl-2 take part in the regulation of proliferative cells in epiretinal membrane of traumatic proliferative PVR, with high correlation with the dynamic changes of cell proliferation.

Objective:To investigate the effect of carvedilol on expression of cardiac matrix metalloproteinases(MMPs)and tissue inhibitors of metalloproteinases(TIMPs)after myocardial infarction in rats.Methods:An animal model of acute myocar- dial infarction(AMI)was established by descending left coronary artery ligation in 24 rats and they were divided into carvedilol (10 mg?kg~(-1)?d~(-1))group(n=12)and normal saline group(n=12).Sham operated group(n=9)received the same proce- dure but with no ligation.All animals were treated for 6 weeks via a gastric lavage.Heart function and hemodynamic parame- ters were determined after 6 weeks.The protein expression of cardiac MMP-2,MMP-9 and TIMP-2 was detected by immuno- histoehemical analysis in AMI groups,and the MMPs activities were assessed by zymography.Gene expression of myocardial MMPs/TIMPs(MMP-2,9 and TIMP-1,2)and cytokines(TNF-?,IL-1?)were measured by real-time quantitative PCR.Re- suits:Compared with Sham-operated group,earvedilol group had significantly higher left ventricular end-diastolic pressure(LV- EDP)and lower LV upstroke velocity(+dp/dt_(max))and LV descent velocity(-dp/dt_(max))(P

OBJECTIVETo compare the incidence of metabolic disorders (MS) in patients with primary aldosteronism (PA) and essential hypertension (EH).

METHODSMS prevalence was observed in 200 EH patients (male 104) and 220 PA patients (male 117) hospitalized to our hospital from August 2005 to March 2007.

RESULTS(1) The prevalence of MS in PA group was significantly higher than that of EH group (47.3% vs. 31.5%, P = 0.009). (2) Blood pressure was significantly higher in PA group than that of EH [SBP: (150.67 +/- 15.45) mm Hg vs. (145.69 +/- 17.13) mm Hg, P = 0.042; DBP: (93.03 +/- 10.51) mm Hg vs. (85.83 +/- 14.44) mm Hg, P = 0.037]. (3) Incidences of abdominal obesity (86.8% vs. 78.5%, P = 0.024) and insulin resistance (insulin sensitivity index: 42.42 +/- 16.11 vs. 49.58 +/- 22.43, P = 0.008) were significantly higher in PA group than in EH group.

CONCLUSIONThe prevalence of MS in hospitalized PA patients was significantly higher than that of EH patients characterized by prevalent abdominal obesity, insulin resistant and severe hypertension.

This study was aimed to characterize clinicopathological features and prognosis of patients with adenosquamous lung carcinoma (ASC). Among the 2531 patients with lung cancer who underwent surgery between January 2000 and June 2012 in our hospital, 59 were histologically diagnosed as having ASC. The clinicopathological features and follow-up data of ASC patients were collected and analyzed statistically. Superior lobectomy was accomplished in 40 patients, middle and inferior lobectomy in 3, lobectomy plus partial resection of contralateral lung in 5, partial lung resection in 4, and pneumonectomy in 7. Moreover, 22 cases were found to be adenocarcinoma-predominant, and 18 to be squamous cell carcinoma-predominant. The median survival time was 13.6 months, and the 1-, 3-, and 5-year survival rates were 59.9%, 36.4% and 31.2%, respectively. Of the 52 cases with tissue specimens available, 11 had an EGFR mutation (21.2%) and 2 had a KRAS mutation (3.8%). Multivariate analysis showed that histology subtype, pleural invasion, TNM stage, and postoperative treatment were all independent prognostic factors. The data from the current study demonstrated that SCC-predominant histology represents a better prognosis of ASC. Histology subtype, pleural invasion, TNM stage, and postoperative treatment are independent prognostic factors for ASC and adjuvant therapy may help control the disease.

OBJECTIVETo evaluate the effect of tea polyphenol(TP) on the rat with alcoholic liver damage.

METHODRats were divided into 3 groups, in which 2 groups were stomach perfused with alcohol to result in ALD, and 1 group of them stomach perfused with TP simultaneously. Another group was normal control groups (stomach perfused with drinking water). In the end of 12 weeks, the liver specimen of each rat was observed by anglicizing its tissue damage, and all data collected was performed by statistical analysis in quantum and semi-quantum. Meanwhile cytokines gene express of each group is determined.

RESULTIn the end of 12 weeks, alcoholic hepatitis appeared in rat liver. Hepatic injury in alcohol group and TP group were found, but could not be found in normal group. Compared with pure alcohol group, alcoholic liver damage mainly showing with steatosis in TP group were slight, in addition showing liver cellular swelling with small area, with less spot and focal necrosis, none bridging necrosis. Steatosis were slight relatively, mega-bubble steatosis were less found. Collagen deposition of TP group were less than those of pure alcohol group. Gene expression of. cytokine have diversity statistically such as IL-3, IL-4, IL-1R2, IL-6R, IL-7R2, IL-3Ra, IL-R1, IL-13, IL-1R1, IL-7R2, EPO-R, LIFR, IL-1R2, IL-5R2, CSF1, CD27, IL-6R.

CONCLUSIONTP is able to attenuate alcoholic liver damage. It's mechanism is possibly due to modulating cytokines gene expression of cytokine.

OBJECTIVETo compare the effect of high frequency oscillatory ventilation (HFOV) and conventional mandatory ventilation (CMV) on the myocardial function of rabbits with inhalation injury.

METHODSSteam inhalation injury model was reproduced in 16 New Zealand albino rabbits. They were randomly divided into CMV group (n = 8) and HFOV group (n = 8) by drawing lots, and they received ventilation in metered volume and HFOV treatment respectively. Heart blood was drawn from rabbits before they were sacrificed 4 hours after treatment to determine the plasma activity of lactate dehydrogenase 1 (LDH1) and creatine phosphorylated kinase (CPK-MB). Myocardial tissue from left ventricle was harvested and homogenized to determine the concentration of TNF-α and IL-8, the activity of caspase-1, and the activity of myosin-light-chain kinase (MLCK) and the ATPase of myosin light chain (MLC-ATPase) by enzyme-linked immunosorbent assay, spectrophotometry, and the nuclide liquid scintillation technique respectively. Part of the myocardial tissue sample was examined pathologically. Data were processed with analysis of variance.

RESULTS(1) The activities of LDH1 and CPK-MB in plasma were obviously higher in CMV group than in HFOV group [(643 ± 108), (342 ± 48) U vs. (233 ± 92), (186 ± 36) U, with F value respectively 10.326 and 9.846, P values all below 0.01]. (2) The contents of TNF-α, IL-8 and the activity of caspase-1 in myocardial tissue homogenate were obviously higher in CMV group than in HFOV group [(181 ± 35), (89 ± 19) pg/g, and (0.56 ± 0.27) g/g protein vs. (94 ± 21), (43 ± 11) pg/g, and (0.24 ± 0.12) g/g protein, with F value respectively 8.239, 7.826, 5.716, P values all below 0.01]. (3) The activities of MLC-ATPase and MLCK were lower in CMV group than in HFOV group [(0.24 ± 0.12) µmol×mg(-1)×min(-1), (3.3 ± 1.1) mmol×mg(-1)×min(-1) vs. (0.48 ± 0.16) µmol×mg(-1)×min(-1), (7.7 ± 1.7) mmol×mg(-1)×min(-1), with F value respectively 4.125, 4.766, P values all below 0.01]. (4) No obvious necrosis, degeneration or inflammatory cell infiltration was observed in myocardial tissue of rabbits in 2 groups under light microscope; but the myocardial fiber was slightly swollen, and it was less marked in the HFOV group.

CONCLUSIONSThe influence of HFOV on myocardial myosin phosphorylation system of rabbits with inhalation injury is less than that of CMV.
