Objective To observe the therapeutic effects of medicated thread moxibustion of traditional Zhuang nationality medicine combined with Shugan Jianpi Decoction for cirrhosis ascites. Methods Sixty patients with cirrhosis ascites were randomly divided into observation group and control group by random number method, 30 cases in each group. The treatment group received medicated thread moxibustion of traditional Zhuang nationality medicine combined with Shugan Jianpi Decoction and regular Western medicine; while control group only received regular Western medicine. Two weeks was a course of treatment. The liver function (ALT, AST, TBIL, ALB, A/G), ascites integral changes and improving time of main clinical symptoms (abdominal distension, pain, anorexia, fatigue) were observed. The clinical curative effects of two groups were evaluated with 3 months of follow-up. Results The liver function (ALT, AST, TBIL, ALB, A/G) in the treatment group after treatment was significantly improved, and the ascites integral decreased, which was better than the control group, with statistical significance (P<0.05). The improving time of main clinical symptoms in the treatment group was significantly shorter than the control group (P<0.05);The clinical effective rate was 90.00%(27/30) in the treatment group and 76.67% (23/30) in the control group, with statistical significance (P<0.05). Conclusion Medicated thread moxibustion of traditional Zhuang nationality medicine combined with Shugan Jianpi Decoction has good efficacy for cirrhosis ascites.

OBJECTIVEThe cascade of physiological events underlying hypoxic-ischemic brain damage (HIBD) remains to be fully established. The perinatal brain shows both an increased tolerance to hypoxic-ischemic (HI) injury and a faster and more complete recovery than the adult. It is, therefore, important to understand the sequence of events following hypoxia and ischemia in young animals. The present study aimed to clarify the time-course of the activation of the mu-calpain, and the expression of c-Fos, c-Jun, HSP70 and HSP27 proteins following severe HI (2 h hypoxia) and their relationship with each other.

METHODSA modified newborn rat model of HIBD that included a combination of hypoxia and ischemia as described by Rice was used. Forty-two postnatal 7-day-old Sprague-Dawley rats were randomly divided into seven groups (6 rats in each): 6 time-window groups and a normal control group. Samples were collected at 0, 1, 2, 4, 12 and 24 h after HI insults. The protein concentration was determined using a modified Bradford assay. mu-calpain activation, c-Fos, c-Jun, HSP70 and HSP27 expressions were observed respectively by Western blot from cortical and hippocampal samples.

RESULTSThe cleavage of cytosolic mu-calpain was observed from both cortical and hippocampal samples in neonatal rats after HI. The ratio 76:80 of mu-calpain was increased significantly post-HI and reached a maximum at 24 h in cortex and at 12 h in hippocampus after HI. The expressions of c-Fos and c-Jun from both cortical and hippocampal samples in neonatal rats were up-regulated and peaked at 2 or 4 h after HI, demonstrating significant differences at 1, 2, 4, and 12 h compared with that observed in the control (P < 0.05). When compared with that observed in cortex, the nuclear c-Fos expression from hippocampal samples was highly elevated at 2, 4 and 12 h but significantly decreased at 24 h after HI (P < 0.05), while the nuclear c-Jun expression from hippocampal samples was highly elevated at 0 and 1 h but significantly decreased at 4 and 24 h after HI (P < 0.05). Similarly, the expressions of HSP70 and HSP27 from both cortical and hippocampal samples were up-regulated and reached a maximum at 12 or 24 h after HI, demonstrating significant differences at 12 or 24 h both in cortex and hippocampus for HSP70, and at 24 h in cerebral cortex as well as at 12 and 24 h in hippocampus for HSP27 compared with the control (P < 0.05). Furthermore, in comparison with that observed in cortex, the HSP70 expression from hippocampal samples was highly elevated at 1 h, but significantly decreased at 4, 12 and 24 h after HI (P < 0.05), while the HSP27 expression was permanently elevated in hippocampus after HI.

CONCLUSIONThe neuronal injury induced by HI insults appears to involve many ongoing and simultaneous mechanisms. HI activates the calpains immediately, which may contribute to neuron apoptosis, and induces a significant brain neuroprotection, since there is an increased HSP70 expression and a relatively late remarkable HSP27 expression in hypoxic-ischemic neonatal rat brain. Nuclear c-Fos and c-Jun may participate in the pathogenesis of HIBD.

OBJECTIVERespiratory syncystial virus (RSV) is the most common cause of lower respiratory infections in infants worldwide. There is no reliable vaccine or antiviral drug against RSV at present. RNA interference (RNAi) technology is a potent method to degrade expression of the cognate mRNA. In order to inhibit the replication of RSV at gene level, the effects of specific RNAi against M2-1 gene of RSV on inhibition of viral replication in cell culture system was observed in this study.

METHODSRSV M2-1 gene, which plays a key role in RSV transcription, was chosen in this study and was used as target gene and recombinant plasmid pshRNA7816 targeting the mRNA of RSV M2-1 gene coding sequence was constructed. The pshRNA7816 was transfected into Hep2 cells. The effects of the pshRNA7816 on changes of cytopathogenic effect (CPE) of Hep2 cell induced by RSV infection were observed microscopically. Viral plaque forming assay and MTT assay were used to detect the viral titer change and protective function of the pshRNA7816 on RSV infected Hep2 cell.

RESULTSThe recombinant RNAi plasmid pshRNA7816 which targets the mRNA of RSV M2-1 gene was successfully constructed. The pshRNA7816 significantly reduced CPE of RSV infected Hep2 cells, reduced the viral titer of RSV in the cells (P < 0.001). The pshRNA7816 raised the survival rate of RSV infected Hep2 cells (P < 0.001). Non-specific pshRNA plasmid did not show anti-RSV effects (P > 0.05).

CONCLUSIONThe recombinant pshRNA7816 plasmid which targeted the mRNA of RSV M2-1 gene showed a significant and specific anti-RSV effect.

This study was aimed to investigate the effect of baicalin on proliferation and apoptosis of HL-60 cells and its mechanism. Cell proliferation was assayed by using Cell Counting Kit-8. The morphological changes of HL-60 cells were examined by light microscopy and nucleolus morphological changes were observed by fluorescent microscopy after Hoechst 33342 staining. The early cell apoptosis was detected by using flow cytometry with Annexin V-FITC/PI double staining. The expression of caspase-3, caspase-9, Bcl-2 and Bax mRNA was detected by RT-PCR and Western blot assay was carried out to examine Bax, Bcl-2, caspase-8 and cleaved caspase-3 expression. The results showed that Baicalin inhibited the proliferation of HL-60 cells in a time- and concentration-dependent manner. HL-60 cells exhibited typical morphological features (for example, cell shrinkage, membrane blebbing and formation of apoptotic bodies). Cell apoptosis in early stage could be detected, the expression of caspase-3, caspase-9 and Bax mRNA was obviously up-regulated, while the Bcl-2 expression down-regulated, and accordingly Bcl-2/Bax ratio decreased. Such results were consistent with the expression of these proteins. In addition, the expression of cleaved caspase-8 protein was induced significantly after treated with baicalin. It is concluded that baicalin can significantly inhibit the proliferation of HL-60 cells and induce the apoptosis of HL-60 cells, which may occur through decreasing Bcl-2/Bax ratio by intrinsic pathway and through extrinsic pathway. It suggests that baicalin may be a promising drug for the therapy of acute myeloid leukemia.

The objective of this study was to detect the expression frequency of HLA-DR15 in patients with aplastic anemia (AA) and myelodysplastic syndrome (MDS), to investigate the relation of expression frequency with diseases and to analyze the relationship between immunoglobulin, T lymphocyte subsets and HLA-DR15. HLA-DR15 expression was detected by PCR-SSP; immunoglobulin was detected by immune turbidimetry; T cell subsets were detected by flow cytometry. The results showed that the expression rates of HLA-DR15 in AA and MDS as well as normal control groups were 78.6%, 63.2% and 24.6% respectively. The difference between AA, MDS and the normal control groups was statistically significant (p < 0.01). OR (odds ratios) values of AA and MDS groups were 11.262, 4.710 respectively. Compared with normal control group, expression rate of HLA-DR15 in hematologic malignancy group was not significantly different. The immunoglobulin level and abnormal T cell subsets in AA and MDS groups were statistically different between HLA-DR15 positive and negative groups (p > 0.05). It is concluded that the frequency of HLA-DR15 antigen in AA and MDS patients is significantly higher than that in normal control and hematologic malignancy group. OR value>1 showed a positive correlation between the diseases and HLA-DR15. HLA-DR15 is a susceptible gene in AA and MDS. The abnormalities of immunoglobulin level and ratios of T cell subsets in AA and MDS are common, but are not associated significantly with the expression of HLA-DR15.

OBJECTIVETo investigate whether activation of mitochondrial aldehyde dehydrogenase 2 (ALDH2) and inhibition of mitochondrial permeability transition pore (mitoPTP) were involved in the cardioprotection of ethanol postconditioning in isolated rat heart.

METHODSHearts isolated from male Sprague-Dawley rats were perfused on a langendorff apparatus and subjected to 30 min of regional ischemia (occlusion of left anterior descending artery) followed by 120 min of reperfusion. The ventricular hemodynamic parameters and lactate dehydrogenase (LDH) release during reperfusion were measured. Infarct size was measured by TTC staining method and the expression of ALDH2 at mRNA level of left anterior myocardium was detected by RT-PCR.

RESULTIn contrast to ischemia and reperfusion, ethanol postconditioning improved the recovery of left ventricular developed pressure, maximal rise/fall rate of left ventricular pressure during reperfusion, reduced LDH release and infarct size. The expression of ALDH2 mRNA level was increased. Administration of mitoPTP activator atractyloside attenuated the effect of ethanol postconditioning, LDH release and infarct size were increased, and the recovery of hemodynamic parameters was inhibited. The expression of ALDH2 mRNA was decreased.

CONCLUSIONEthanol postconditioning has cardioprotection effect, which may be associated with upregulating mitochondrial ALDH2 mRNA expression and inhibiting the opening of mitochondrial permeability transition pore.
