Objective The purpose of this study was to explore the expression of human fibrinogen-like protein 2 (hFgl2) in patients with cryptococcal meningitis (CM).Methods The expression of hFgl2 in the peripheral blood leukocytes from 20 CM cases and 20 healthy individuals,and the expression of hFgl2 in cerebrospinal fluid (CSF) leukocytes in 11 pairs of CM patients and matched controls was detected using immunohistochemical methods.Medical image analysis system (MIAS) was used to analyze the expression of hFgl2 gray values,which were negatively correlated to the expression of hFgl2 protein in both peripheral blood and CSF.Results The average gray values for hFgl2 protein in peripheral monocytes of CM patients and healthy controls were 114.49± 11.82 and 137.56± 10.64,respectively,and those in peripheral neutrophils were 111.71 ± 8.62 and 143.56±12.57,respectively.Compared with the healthy control group,expressions of hFgl2 in peripheral blood monocytes and neutrophils were both significantly increased in CM patients (t =21.21,t=27.19; P＜0.01).The average gray values for hFgl2 protein in CSF monocytes from CM patients and negative controls were 115.44±8.67 and 149.25±8.57,respectively,and those in CSFneutrophils were 111.71±8.62 and 143.56 ± 12.57,respectively.The expressions of hFgl2 in CSFmonocytes and neutrophils were significantly increased in CM patients (t =29.95,t=28.87; P＜0.01),while the expression intensity of hFgl2 was similar when peripheral blood monocytes and neutrophils compared with their CSF counterparts (t=0.924,t=0.607; both P＞0.05).Conclusions hFgl2 can be expressed in both peripheral and CSF monocytes and neutrophils in CM patients.

objective To determine the relationship between immunohistochemical stain assay of liver tissue and prognosis of viral hepatitis.Methods 132 patients with chronic hepatitis B diagnosed 6 to 8 years ago by liver biopsy had been followed up by the retrospective and prospective study.The serum hepatitis B virus markers(HBVm)?alpha-fetoprotein(AFP)?Alanine aminotransferase(ALT) and Aspartate aminotransferase(AST)have been detected and B-scan ultrasound of liver and spleen have performed when they stayed at hospital and during follow-up-time,their symptom and physical sign have been recorded simultaneously.Results 4 of 104(3 85%) patients died of cirrhosis;of 100 survival patients,2 patients(2%,2/100) were typical cirrhosis and 16 (16%,16/100) patients were early stage cirrhosis and parenchyma of liver diffuse lesion diagnosed by ultrasound.The serum ALT of patients whose HBcAg and HBsAg were positive in liver tissue was easier fluctuation than those of negative case.Conclusion The status of patients with HBsAg and HBcAg positive in liver tissue is easier fluctuation than those negative,HBsAg and HBcAg positive in liver tissue maybe have no effect on the prognosis of the chronic hepatitis B.

Objective To explore the relationship between mutations in basic core promoter (BCP) of hepatitis B virus (HBV) and familial clustering of hepatocellular carcinoma (HCC) in Guangxi. Methods 153 pairs of members with HBsAg-positive were selected and matched from HCC high-incidence families and carcinoma-free families in Guangxi. The BCP genes were amplified and sequenced. Results The hotspot sites of the previous five mutations in BCP were T1762, A1764, G1775, V1753, G1803. In univariant analysis, HBV DNA≥105 copies/mL, T1762, A1764 and V1753 mutations were associated with the HCC high-incidence (P <0.05). The multivariate logistic analysis showed that HBV DNA≥105 copies/mL and A1764 were independent risk factors for it. Conclusion HBV DNA level, the mutations in BCP showed correlations with familial clustering of HCC in Guangxi.

OBJECTIVE To study the correlation of hepatitis B virus(HBV)basic core promoter(BCP) mutation with the interleukins(IL-10,IL-12),tumor necrosis factor(TNF)-?,interferon(IFN)-?,as well as HBV DNA contents in patients with chronic hepatitis B virus infection.METHODS(1) Project subject: 176 patients(chronic hepatitis B with mild,moderate and severe degree;liver cirrhosis,chronic fulminant and hepatocellular carcinoma(HCC)) with chronic hepatitis B virus infection were studied.(2) Project methods: ① The A to T mutation at nucleotide 1762 and G to A mutation at nucleotide 1764 were determined by the method of polymerase chain reaction(PCR) microplate hybridization ELISA in these patients.② The serum cytokines(IL-10,IL-12,TNF-? and IFN-?) of these patients were measured by specific-ELISA.RESULTS The serum levels of cytokines(IL-10(80.96?30.86 vs 72.11?24.19 mg/L),IL-12(41.33?15.10 vs 35.98?14.47 mg/L),TNF-?(56.04?27.05 vs 38.01?10.49 mg/L),IFN-?(19.81?12.29 vs 16.55?8.99 mg/L))and HBV DNA contents(108.2478?0.9826 vs 105.8876?1.4822copies/ml) in BCP mutant group were significantly higher than that in non-mutant group(P

OBJECTIVE To investigate the relationship among hepatitis B virus(HBV) basic core promoter(BCP) mutation,serum HBV DNA contents and HBV markers as well as liver function of chronic hepatitis B patients.METHODS The A to T mutation at nucleotide 1762 and G to A mutation at nucleotide 1764 were determined by the method of polymerase chain reaction(PCR) microplate hybridization ELISA in 176 patients with chronic hepatitis B virus infection.RESULTS The rate of HBV BCP mutants in negative and positive groups of HBeAg was 49.4% and 33.3%,respectively(P

Aim To explore the effects of lipoteichoic acid (LTA) induced delayed preconditioning (PC) on hypoxia-reoxygenation (H/R) injury of cultured human coronary artery endothelial cells (HCAECs), and to investigate the potential role of endogenous nitric oxide (NO) participated in the protective mechanism. Methods HCAECs were incubated for 2 h in a hypoxic atmosphere and reoxygenated for 4 h in a normoxic atmosphere. The delayed PC was induced by pretreatment with LTA assessed by the percentage of cellular injury with Trypan blue exclusion and by the amount of lactate dehydrogenase (LDH) in culture media. The NO level of the culture media was measured detect the expression of eNOS mRNA by RT-PCR method after cells were recovered from different points.Results LTA pretreatment significantly decreased the percentage of the killed cell and the concentration of LDH in media. Also, LTA pretreatment obviously raised the concentrations of NO in culture media. The protective effects of LTA were abrogated by pretreatment with N-monomethyl-L-arginine (L-NMMA).Moreover, the expression of eNOS mRNA was significantly upregulated after HCAECs exposure to LTA for 4 h following 2 h or 4 h recovery. Conclusion LTA could induce the delayed protection against H/R induced endothelial injury and dysfunction of cultured HCAECs. NO produced by eNOS acts initially as a trigger and subsequently as a mediator of delayed PC.

AIM: To study the potential effects of lipoteichoic acid (LTA)-induced delayed preconditioning (PC) on cardioplegic arrest/reperfusion injury in donor rat heart. METHODS: The rats were pretreated with LTA (1 mg/kg, ip) 24 h before the experiment, and the isolated hearts were subjected to arrested by cardioplegic solution and stored in Eurocollin's solution for 4 h by the Langendorff method, and to evaluate the changes of cardiac function at the reperfusion for 30 min and 60 min, to measure the amounts of MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH) and total nitric oxide (NO) oxidation products in the coronary effluent, and to detect myocardial apoptosis on tissue samples of left ventricle at the end of reperfusion by TUNEL staining. RESULTS: Pretreated with LTA significantly improved the recovery of cardiac function with a significant increase in coronary flow (CF), left ventricular developed pressure (LVDP), maximal rate of left ventricular developed pressure (+dp/dt_ max), and minimal rate of left ventricular decline pressure (-dp/dt_ max) at 30 min and 60 min of reperfusion (all P
