OBJECTIVETo investigate the influence of lipopolysaccharide (LPS) on macrophages expressing TNF-alpha related apoptosis induced-ligand (TRAIL) and its relation to apoptosis of HepG2 cell line.
METHODSMembrane-bound TRAIL (mTRAIL) was measured by flow cytometry; soluble TRAIL in supernatant was detected by enzyme-linked immunoabsorbent sandwich assay (ELISA); cytotoxicity of TRAIL to HepG2 cell line was measured by chromium release assay, and apoptosis of HepG2 cell was confirmed by Annexin V staining.
RESULTSLPS only slightly increased membrane-bound TRAIL expression of macrophages. On the other hand, soluble TRAIL in the supernatant was increased with LPS stimulation, and the optimal concentration of LPS was 100 ng/ml (sTRAIL value 67.40 ng/ml+/-5.08 ng/ml). The soluble TRAIL in the supernatant was cytotoxic to HepG2 cells, and this activity can be blocked by TRAIL neutralizing antibodies.
CONCLUSIONLPS increases the expression of soluble TRAIL in macrophages, and soluble TRAIL is toxic to HepG2 cells. All of our results indicate that TRAIL may play an important role in the pathogenesis of viral hepatitis.

OBJECTIVETo observe the effect of salvia miltiorrhiza and ligustrazine injection on the early myocardial damage of severely burned patients.
METHODSTwenty severely burned patients hospitalized from January 2010 to August 2011, with burn area equal to or more than 50% TBSA, were divided into two groups following hospitalization sequence, with odd number patients entering treatment group (T, n = 10) and even number patients entering control group (C, n = 10). Patients in C group were treated with routine methods, including fluid resuscitation based on the Third Military Medical University formula, anti-infection treatment, support treatment, and organ-protection treatment, etc. In addition to routine treatment methods, patients in T group received intravenous infusion of 250 mL glucose injection (50 g/L) containing 10 mL salvia miltiorrhiza and ligustrazine concoction, once a day, and continued for three days. Venous blood of patients was drawn at post burn hour (PBH) 12, 24, 48, and 72 to determine the plasma levels of cardiac troponin I (cTnI), creatine kinase isozyme MB (CK-MB), and atrial natriuretic peptide (ANP). Data were processed with t test.
RESULTSAt each time point, levels of cTnI, CK-MB, and ANP were lower in T group than in C group. Differences in contents of these parameters between two groups were statistically significant at most time points, with t values from 2.136 to 2.918, P < 0.05 or P < 0.01. Plasma levels of cTnI, CK-MB, and ANP in both groups peaked at PBH 12, which were respectively (28 ± 10) ng/mL, (76 ± 13) U/L, (430 ± 87) pg/mL in T group, and (38 ± 11) ng/mL, (87 ± 10) U/L, (453 ± 91) pg/mL in C group. From PBH 24 to 72, contents of above-mentioned parameters decreased gradually in both groups.
CONCLUSIONSEarly use of salvia miltiorrhiza and ligustrazine injection in severely burned patients can effectively reduce myocardial damage, thus protect the myocardium from injury.

BACKGROUNDThe management of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL) is still controversial and it is advisable to make a triage for these two cytological abnormalities. P16(INK4) (P16) has been shown to be a potential biomarker for predicting high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer. The aim of the study was to determine the value of P16 expression by immunostaining method compared with high-risk human papillomavirus (HR-HPV) DNA test in the triage of ASCUS/LSIL women.
METHODSTotally 86 eligible residual liquid-based cytological specimens with ASCUS and 45 with LSIL were obtained. All specimens were submitted to HR-HPV DNA test (HC2) and P16 immunocytochemical staining simultaneously. And all women underwent colposcopy and biopsy after cytology.
RESULTSThe positive rate of P16 staining was 32.6% in ASCUS and 42.2% in LSIL, which was significantly lower than that of HR-HPV test in both ASCUS (P < 0.05) and LSIL (P < 0.05). Moreover, the positive rate of P16 staining was 12.7% in normal histology, 61.5% in CIN 1, 87.0% in CIN 2-3, and 100.0% in cancer, in which P16 positive rate was significantly lower than HR-HPV positive rate in normal group. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of P16 staining for predicting CIN 2 or more were 87.5%, 68.6%, 38.9%, 96.0%, and 72.1%, respectively in the ASCUS; while 90.0%, 71.4%, 47.4%, 96.2% and 54.7%, respectively in the LSIL, in which the specificity and accuracy of P16 staining were significantly higher than those of HR-HPV test in both ASCUS and LSIL (P < 0.05).
CONCLUSIONP16 immunostaining had significantly higher specificity and accuracy than HR-HPV DNA test for predicting for high-grade CIN and cervical cancer in ASCUS and LSIL and can be used for the triage of women with ASCUS/LSIL cytological abnormality.

OBJECTIVETo study the prevalence of hepatitis B virus (HBV) genotype in 5 cities of Fujian province and the clinical implications of distinct genotypes in HBV-related liver diseases.
METHODSHBV genotype was determined by the restriction fragment length polymorphism analysis in patients with chronic HBV infection in 5 cities of Fujian province. The relationship between HBV genotype and its clinical implications was studied by multinomal logistic regression and correspondence analysis.
RESULTSOf the 431 HBV DNA positive patients detected by PCR, 275 (63.8%) belonged to HBV genotype B, 100 (23.2%) to genotype C, 51 (11.8%) to genotype D and D-mixed genotype. Genotype A, E and F were not found. Multinomal logistic regression showed that genotype B was more prevalent in Quanzhou and Sanming cities than in Fuzhou (P = 0.002, P = 0.006), and genotype B appeared significantly more common in asymptomatic carriers (ASC), chronic hepatitis B (CHB) and severe hepatitis (SH). Genotype C was most prevalent in patients with liver cirrhosis (LC) (47.0%) than in those with ASC (14.5%) and SH (14.7%) (P = 0.009, P < 0.001). The positive rate of hepatitis B e antigen was higher in patients with genotype C than in those with genotype B and genotype D (56.0% vs. 52.4%, P = 0.008, and 56.0% vs. 30.8%, P = 0.051, respectively). By correspondence analysis, genotype D and D-mixed genotype seemed to be correlated with hepatocellular carcinoma (HCC).
CONCLUSIONS(1) The major popular genotypes of HBV were B, C and D in Fujian. (2) Data of our study suggested that the geographic distribution of genotype B and C might be different in some cities of Fujian. (3) Genotype B might have a tendency to lead to SH in younger patients with chronic hepatitis B and the development of LC might be associated with genotype C among the elder patients. (4) Genotype D appeared to associate with development of HCC, which called for further study to confirm.

AIM:To observe the effect of central prostaglandin E2(PGE2) on sympathetic activation in chronic heart failure (CHF) and to explore the underlying mechanism. METHODS:Male SD rats were subjected to coronary ar-tery ligation to induce heart failure (HF), and the intracerebroventricular infusion was performed by osmotic pump continu-ously. The rats in sham group and HF group were given artificial cerebrospinal fluid (0. 25 μL/h). The rats in HF plus treatment group was given celecoxib (CLB; 20 mg/h). After 4 weeks, the levels of PGE2 in cerebrospinal fluid ( CSF), the sympathetic nerve excitability and cardiac function were measured, and the changes of corticotropin-hormone releasing hormone ( CRH)-containing neurons activation and neurotransmitter contents in the hypothalamic paraventricular nucleus ( PVN) were also determined. RESULTS:Compared with the sham-operated rats, the HF rats had raised level of PGE2 in CSF, up-regulated renal sympathetic nerve activity and plasma norepinephrine, increased left ventricular end diastolic pres-sure, lung-to-body weight and right ventricular-to-body weight ratios, and decreased maximal increase and decreased rate of left ventricular pressure (P<0.05). In addition, the number of CRH positive neurons in PVN and the level of plasma ad-renocorticotropic hormone were higher in HF rats than those in sham-operated rats (P<0.05). After administration of CLB into the lateral ventricle of HF rats, the contents of PGE2 in CSF were significantly reduced, the number of activation CRH neurons in PVN was decreased, the excitability of sympathetic nerves was down-regulated and cardiac function was im-proved (P<0.05). Compared with the sham-operated rats, the content of glutamic acid in PVN of HF rats was increased, the content of γ-aminobutyric acid and the number of glutamate decarboxylase 67-positive neurons were decreased ( P<0.05). After the CLB was given, the above indexes were reversed (P<0.05). CONCLUSION:These findings indicate that in CHF, the increased central PGE2 may activate CRH-containing PVN neurons and contribute to the augmented sym-pathetic drive possibly by modulating the neurotransmitters within the PVN.
