OBJECTIVEUsing polymerase chain reaction-reverse blot dot (PCR-RDB) technique to establish a new method for hepatitis C virus (HCV) genotyping and to study the distribution of HCV genotypes in Foshan area.
METHODSHCV primers and probes were designed in 5'-untranslated region (nt-1-nt-299) of HCV. HCV RNA in serum was isolated and purified, and its cDNA was obtained by reversed transcription. Nested PCR using biotin-labelled primers, was done. PCR products were hybridized with immobilized specific probes (genotype 1a to 3b) on Biodyne C membrane to genotype HCV by color development while adding POD and TMB. A certain judgment could be made according to the position of color reaction. The reliability of this new method was verified by sequencing. HCV RNA levels in serum were determined by real time fluorescent quantitative (FQ)-PCR. 60 FQ-PCR-positive HCV sera from Foshan area were genotyped using this assay.
RESULTSAll 60 sera could be successfully genotyped by PCR-RBD. 50 (83.3%) cases were found to be genotype 1b, 2 (3.3%) as genotype 1a and 2 (3.3%) as genotype 2a while 5 (8.0%) to be mixture of genotype 1a and 1b, and 1 (1.7%) to be mixture of genotypes 1b and 2a. No genotypes 2b, 3a and 3b were found. The results of PCR-RDB genotyping methods coincided with sequence analysis.
CONCLUSIONNewly established HCV genotyping system was proved to be sensitive, specific, precise and economic, thus suitable for clinical and epidemiologic studies. The results of HCV genotyping showed that genotype 1b was the predominant genotype in Foshan area.

OBJECTIVEIn order to characterize the feature of stress response induced by stressor with both physical and psychological natures, the effects of water restriction performed in different experimental modes on the physiological parameters, psychological behavioral manifestations and brain c-Fos expressions were observed and compared.
METHODSFifty-eight male Wistar rats were used and randomly divided into three experimental groups (n = 18 for each) and a control group (n = 4). In control group, the rats were allowed to access drinking water freely at all experimental period. In the experimental groups the water supply to the rats was restricted. In timed water supply (TW) group, the water was supplied twice a day, 10 min for each in fixed hours every day. In empty bottle-served (EB) and water-restricted (WR) groups, the water was served only once a day for 10 min, either in the early morning or evening, and in the other time point scheduled for water supply only an empty bottle without water was provided in the EB group and nothing was given in the WR group. The quantities of drank water and eaten food, weight-gaining, and behavior score were observed every day. The serum level of corticosterone was assayed and the rats were sacrificed with fixative perfusion of 3 d, 7 d or 14 d, respectively, following water restriction (n = 6 for each time point in each group). The brain c-Fos expressions were examined with immunohistochemical method.
RESULTSThe slow down of weight-gaining, rise of serum corticosterone level, occurrence of psychological behavioral manifestations of unpeaceful restlessness such as exploring and attacking, enhance of c-Fos expression in the subfornical organ (SFO), median preoptic nucleus (MnPO), area postrema (AP), hypothalamic paraventricular nucleus (PVN), supraoptic nucleus (SON), medial (MeA) and central (CeA) amygdaloid nucleus and ventrolateral septum (LSV) were noticed in both EB and WR groups, except the nucleus of solitary tract (NTS) in which the Fos expression was decreased. The changes of Fos expression in most of nuclei in EB group began at day 3, at least persisted till day 7, and backed down at day 14, while in WR group, similar changes started at day 7 and reached its peak at day 14. In TW group, only the concentration of corticosterone at day 7 was slightly increased and the rest indexes observed were unchanged.
CONCLUSIONThe results indicate that water restriction induces physical as well as psychological stress responses. And the water restrictions experimentally executed in different modes result in different manifestations of behavioral response and brain immediately early gene expression in discrete brain nuclei/regions.

OBJECTIVETo study the clinical efficacy of three kinds of hybrid bioartificial liver support systems (HBLSS) in treating chronic severe hepatitis.
METHODSA bioartificial liver support system (BAL), comprising porcine hepatocytes and fiber tube style bioreactor, was constructed. Then three kinds of HBLSS were constructed: Molecular absorbent recirculating system (MARS) plus BAL; slow plasma exchange (SPE) plus continuous hemodiafiltration (CHDF) and BAL; and SPE plus hemoperfusion (HP) and BAL. One hundred-twenty patients in middle or late stages of chronic severe hepatitis were enrolled in this study. They were randomly divided into 6 groups: H1 group was treated with BAL+MARS, H2 with BAL+SPE+CHDF and H3 with BAL+SPE+HP (as treatment groups); C1 group was treated with MARS, C2 with SPE+CHDF and C3 with SPE+HP (as control groups). The changes in the clinical symptoms, in the hepatic encephalopathy stages, and in the serum total bilirubin (TBIL), the serum albumin (ALB), the prothrombin activities (PTA), endotoxin, ammonia, creatinine and a-fetal protein (AFP) were all observed before the treatment, right after it and 72 hours later. The improving and curing rates and the rates of side effect occurrences in each group were observed.
RESULTSIn all 6 groups, the patients' clinical symptoms ameliorated; their TBIL, endotoxin and ammonia levels decreased (P<0.05), and their PTA and AFP levels lowered significantly (P<0.05). But in the H1, H2 and H3 groups they were more distinctive than in the control groups. In H1 and H2 groups creatinine and ammonia levels were decreased more significantly than in the H3 group (P<0.05). The improving and curing rates of each group were 65 % (13/20), 60% (12/20), 45% (9/20), 45% (9/20), 40% (8/20) and 20% (4/20) respectively. No serious side effects were observed during the treatment.
CONCLUSIONIn treating middle and late stage chronic severe hepatitis, the measures used in H1, H2 and H3 are better than those in C1, C2 and C3. Furthermore, H1 and H2 treatments can ameliorate hepatic and renal functions, prevent the development of multiple organ dysfunction syndrome, and are better than those used in H3.
