The Infectious hypodermal and hematopoietic necrosis virus (IHHNV) and Taura syndrome virus (TSV) are two important shrimp viruses in cultured shrimp in America. These two viruses were transmitted to China at the beginning of the 21st century. In this study, 214 shrimp samples of Penaeus vannamei were collected from seven different areas of China and tested by PCR for IHHNV and TSV infection. The results showed that there were a high prevalence of IHHNV (65.42%) and low prevalence of TSV (3.27%) in the tested samples. Several samples were found to be co-infected with these two viruses. A 3 kb fragment of 7 positive IHHNV samples and a structure protein region (ORF2) of three TSV positive samples were amplified and sequenced. The sequence comparison indicated that both IHHNV and TSV sequenced in China have a low genetic variations compared with the prototype IHHNV and TSV from Hawaii. Phylogenetic analysis showed that TSV isolates were clustered into two groups, Asia and America group, which was genetically correlated to geographic distribution.

Objective To explore the changes of genes associated with the nuclear factor of kappa B(NF-?B) signaling pathway in neonatal rats with early hypoxic-ischemic reperfusion brain damage(HIRBD).Methods Twenty-four SD rats at age of 7 days,with male to female of 1212,were randomized into normal control group(group A,n=8),hypoxic-ischemia reperfusion for 2 h(group B,n=8) and hypoxic-ischemia reperfusion for 4 h(group C,n=8).The tissues of hippocampus were taken for complete RNA extraction.Gene chip inspection and biological signal analysis technique were used to detect the expression of 113 involved signal molecules of NF-?B pathway.Results Compared with group A,the up-regulated expression was found in Chemokine(C-C motif) ligand 2,Dual specificity phosphatase 1,FBJ osteosarcoma oncogene(Fos) and Toll-like receptor 9.Whereas the expressions of Caspase-1,8,Mitogen-activated protein kinase kinase 6,Mitogen activated protein kinase 3 and Ras homolog gene family member a from Ras-gene famimly was found down-regulated in group B.The up-regulated expression was in Fos,IL-1? and Toll-like receptor 6,but that of down-regulation was found in Caspase-1,Extracellular matrix protein 1,Lysophosphatidic Acid G-protein-coupled receptor 2,Mucosa associated lymphoid tissue lymphoma translocation gene 1,Inhibitor of kappa B kinase epsilon and Ras homolog gene family member c.Conclusions At the early stage of HIRBD,the Toll-like receptors may induce NF-?B activation,leading to the coordinated induction of multiple genes,which is involved in inflammatory,apoptosis and cell proliferation.Genes induced by NF-?B are responsible for the physiopathological process of early brain damage in neonatal rats with HIRBD.

OBJECTIVETo investigate the mechanisms of Kebimin decoction (KD) in treating allergic rhinitis (AR).

METHODSSixty patients with AR were randomly divided into two groups, patients in the treated group (TG) were treated with KD, those in the control group (CG) were given Xinfang rhinitis capsule. The serum levels of adhesion molecule (sICAM-1, P-selectin), Th1 cytokines, including interferon-gamma (IFN-gamma) and interleukin-2 (IL-2), and Th2 cytokines (IL-4 and IL-5) were determined by enzyme-linked immunosorbent assay (ELISA) before and after treatment, and compared with those in 30 healthy subjects as control.

RESULTSThe serum levels of adhesion molecule and Th2 cytokines were higher and Th1 cytokines were lower in AR patients than those in healthy control (P < 0.01). After treatment, these indexes were restored significantly (P < 0.01) in the treated group, but no significant change was found in the control group.

CONCLUSIONKD has definite effect in treating allergic rhinitis by inhibiting production of adhesion molecule and regulating the levels of Th1/Th2 cytokines to correct the imbalanced Th1/Th2 cytokines network.

Objective To investigate the association between genetic polymorphisms of ERCCl-C8092A and susceptibility to liver cancer, as well as the gene-environmental interaction on the etiology of liver cancer in Fuzhou. Methods A case-control study was conducted to collect the information on environmental exposure while genetic polymorphism of ERCC1 was analyzed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. General relative risk regression models were further applied to fit the interaction between genetic polymorphisms of ERCC1-C8092A and the environmental factors of liver cancer. Results ERCC1-C8092A variant genotypes were associated with significant increasing risk of liver cancer adjusted odds ratio (OR= 3.789,95%CI:2.792-5.142 ), compared to the wild-type homozygote. Data from the analysis of interaction showed that genetic polymorphism of ERCC1-8092A appeared superadditive interaction with drinking pond-ditch or with hepatitis B, and super-multiplicative interaction with eating moldy food. Conclusion The point mutation in ERCC1-8092A was possibly susceptible to liver cancer, and related synergistically with other risk factors in hepatocelluar carcinogenesis in Fuzhou.

OBJECTIVES: To explore the value of the combined use of aspartate aminotransferase-to-platelet ratio index (APRI) and total bile acid (TBA) for predicting parenteral nutrition-associated cholestasis (PNAC) in preterm infants with gestational age <34 weeks. METHODS: A retrospective analysis was performed on medical data of 270 preterm infants born at <34 weeks of gestation who received parenteral nutrition (PN) during hospitalization in the First Affiliated Hospital of Wannan Medical College from January 2019 to September 2022, including 128 infants with PNAC and 142 infants without PNAC. The medical data between the two groups were compared, and predictive factors for the development of PNAC were explored through multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was used to evaluate the value of APRI alone, TBA alone, and the combination of both for predicting PNAC. RESULTS: TBA levels in the PNAC group after 1, 2, and 3 weeks of PN were higher than those in the non-PNAC group (P<0.05). APRI in the PNAC group after 2 and 3 weeks of PN was higher than that in the non-PNAC group (P<0.05). Multivariate logistic regression analysis showed that elevated APRI and TBA after 2 weeks of PN were predictive factors for PNAC in preterm infants (P<0.05). ROC curve analysis showed that the sensitivity, specificity, and area under the curve (AUC) for predicting PNAC by combining APRI and TBA after 2 weeks of PN were 0.703, 0.803, and 0.806, respectively. The AUC for predicting PNAC by combining APRI and TBA was higher than that of APRI or TBA alone (P<0.05). CONCLUSIONS After 2 weeks of PN, the value of combining APRI and TBA for predicting PNAC is high in preterm infants with gestational age <34 weeks.

AIMTo determine the protective effect of ONO-1078, a leukotriene receptor antagonist, on focal cerebral ischemia induced by endothelin-1 in rats.

METHODSSlow microinjection of endothelin-1 (120 pmol in 6 microL, for > 6 min) into the region near the middle cerebral artery was used to induce focal cerebral ischemia. ONO-1078 (0.1 mg.kg-1) was i.p. injected 1 h before endothelin-1 injection. Neurological symptoms, brain edema, brain infarction size, and the survival neurons in cortex and striatum were observed 24 h after ischemia.

RESULTSIntracerebral microinjection of endothelin-1 induced remarkable neurological symptoms, brain infarction, brain edema, and decrease of survival neurons in the cortex and striatum. In rats pretreated with ONO-1078, endothelin-1-induced brain edema and brain infarction size were decreased. The numbers of survival neurons in striatum and cortex were increased significantly. The neurological symptoms were improved but not significantly.

CONCLUSIONONO-1078 possesses neuroprotective effect against cerebral ischemic injury induced by endothelin-1, therefore, leukotrienes may play a role in the injury of cerebral ischemia.
