Objective To observe the effects of telramethylpyrazine(TMP)on the splanchnic blood flow in severe acute pancreatitis(SAP)rats and to elucidate the underlying mechanism.Methods Thirty-two rats were randomly divided into 2 groups:telramethylpyrazine group(TMP group,n=16)and SAP group(n=16).At 12,24 hours after the induction of SAP,serum amylase was measured.The regional pancreatic blood flow was measured by Doppler ultrasound;the blood flow of portal vein,spleen artery and superior mesenteric artery were also measured.Results The level of the serum amylase was lower in the TMP group than that in the SAP group(P

Objective To investigate psychosocial factors for post-stroke depression (PSD). Methods 405 in-pa-tients with stroke were first screened for depression using Comprehensive International Diagnostic Interview-3.0. 22 pa-tients with depression were recruited as the depression group. From 383 patients without depression, 44 patients were se-lected and served as the non depression controlled group according to the sex and age paired with 1:2. Both groups were measured by using questionnaires including Life Event Scale, Simplified Coping Style Questionnaire, Social Support Rat-ing Scale, Activities of Daily Living Scale and Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form. Re-sults The score of passive coping was significantly higher in depression group than in non depression group [(1.2 ± 0.5) vs. (0.8±0.7), P<0.05]. The score of subjective support was significantly lower in depression group than in non depression group [(17.5±4.0) vs. (20.7±4.6), P<0.05]. Logistic regression analysis showed, minority nationality (OR=2.564, 95%CI:1.039~6.327) and passive coping style (OR=2.223, 95%CI:1.052~5.192) were risk factors for PSD, while subjective sup-port was protective factor for PSD (OR=0.884, 95%CI:0.793~0.986). Conclusions Passive coping style and low subjec-tive support may be the important psychosocial factors of PSD.

TrkA is essential components of the high-affinity NGF receptor necessary to mediate biological effects of the neurotrophins NGF. Here we report on the expression of trkA in the cerebral cortex and diencephalon of mongolian gerbils during postnatal development. The expression of trkA was identified by immunohistochemical method. In parietal cortex and piriform cortex, higher levels of trkA-IR (immunoreactivity) were detected at 3 days postnatal (P3) and at P9. Although trkA was not expressed till P3 in the parietal cortex, it was detectable at birth in the piriform cortex. Several regions, such as Layers I, IV & VI, did not show much expression. Layer I showed especially weak labeling. In the hippocampus, thalamus, and hypothalamus, higher levels of trkA-IR were detected at P6 and P12 than earlier days. But trkA was not expressed at birth in the hippocampus, at P3 in the reticular thalamic nucleus (Rt), or neonatally in the dorsomedial hypothalamic nucleus (DM). This data shows that expression of trkA is developmentally regulated and suggests that high affinity neurotrophin-receptors mediate a transient response to neurotrophines in the cerebral cortex and diencephalon during mongolian gerbil brain ontogeny.

[Objective] To investigate the correlation between human leukocyte antigen (HLA) gene polymorphism and hepatitis B virus (HBV) infection. [Methods] Venous blood samples were collected from 501 healthy individuals undergoing physical examinations at Yan’an Hospital in Kunming, Yunnan Province. Enzyme linked immunosorbent assay (ELISA) was used to detect HBV halves. Based on the results of HBV half detection, the patients were divided into three groups: HBV carrier group, previous infection group, and healthy control group. The HLA-A antigen genotype was detected using polymerase chain reaction with sequence specific primers (PCR-SSP) genotyping technology, and the distribution frequency of HLA-A gene polymorphism was compared between HBV carrier group and healthy control group, as well as between previous infection group and healthy control group. SPSS17.0 software was used for data statistical analysis. [Results] In the healthy control group, the HLA-A2 positivity rate was 47.49%, and the allele frequency was 31.29%.The overall frequency of gene distribution in the healthy control group was consistent with the HLA-A allele table commonly and confirmed in China published by the Chinese Bone Marrow Bank. The HLA-A2 positivity rate and allele frequency in the HBV carrier group were 63.04% and 42.23%, respectively; The difference in HLA-A2 positivity rate and allele frequency among carriers was statistically significant (P<0.05). the HLA-A2 positivity rate and allele frequency in the HBV previous infection group were 56.14% and 35.97%, respectively, which did not significantly differ from those in the healthy control group (P>0.05). [Conclusion] HLA-A2 gene may be a susceptibility gene for chronic hepatitis B HBV carriers.
