OBJECTIVE:To observe therapeutic efficacy and safety of amlodipine besylate combined with valsartan in the treatment of hypertension. METHODS:158 patients with hypertension were randomly divided into control group (n=78) and treatment group (n=80). Control group was treated with amlodipine besylate,2.5 mg/time,3 times/d;treatment group was addi-tionally treated with valsartan,80 mg/time,once a day. A treatment course lasted for 4 weeks,and both received 5 courses. Clini-cal efficacy,blood pressure,plasma concentrations of ET-1,NT-proBNP and Ang Ⅱ were compared between 2 groups. RE-SULTS:The compliance rates of treatment group after 4,8,12,16,20 weeks were higher than that of the control group(P<0.05). Compared with control group,SBP and DBP of treatment group were decreased significantly after 4,8,12 and 20 weeks,with sta-tistical significance(P<0.05). After 20 weeks,the serum levels of ET-1,NT-proBNP and Ang Ⅱwere decreased significantly,es-pecially treatment group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR be-tween 2 groups (P>0.05). CONCLUSIONS:Amlodipine besylate combined with valsartan can effectively control the blood pres-sure in patients with hypertension,which may be related to the inhibition of ET-1,NT-proBNP and AngⅡ.

Objective To explore the expression and significance of peripheral blood T lymphocyte subgroups and natural killer cell in children with asthmatic pneumonia.Methods From 2013 to 2016,asthmatic children with pneumonia were erolled in the study as asthmatic pneumonia group(36 cases) and 36 cases medical health children as control group at the same time in Zhongshan City people′s hospital.Flow cytometry was used to test analysis of two groups of T lymphocyte subsets and natural killer cell in serum and the expression of CD28,CD56,using ROC curve analysis results.Results Asthmatic pneumonia group compared with control group,the difference of CD3+ and CD3+CD8+,CD28+,CD8+CD28+,CD8+CD28-,CD3-CD16+CD56+ and CD3+CD16+CD56+,CD3+CD4+/CD3+ CD8+ was statistically significant(P<0.05).According to the results of flow parameters have higher sensitivity by the ROC curve statistics.Conclusion Asthmatic pneumonia children have immune dysfunction,immune function changes associate with asthmatic,which is of great clinical significance to carry out immune function detection for children with asthmatic pneumonia.

Objective To analyze the chemokine receptor CXCR4 expression in acute leukemic cells of children and its relationship with extramedullary infiltration.Methods The immunotypes of cases of acute leukemia in children and the expression of CXCR4 in marrow leukemic cells were studied by flow cytometry respectively. The relationship between CXCR4 expression and extramedullary infiltration of leukemic cells were analyzed by statistical method.Results The expression rates of CXCR4 in ALL children were higher than those in NALL children(P

0.05).Expressions of IL-2 in tears significantly decreased 1 d,1 week and 1 month after LASIK(P0.05).Compared with the expression of NGF in tears before operation,those of 1 d,1 week,1 month and 3 months after LASIK were significantly increased(P

OBJECTIVE: To establish the method for content determination of 12 trace elements (Cu, Mn, Mg, Cd, Zn, Fe, Ba, Se, Pb, As, Cr, Ni) in Shiquan dabu pills, and to provide reference for further improvement of its quality control.METHODS: ICP-OES was adopted to detect. Microwave digestion was used for sample pretreatment with digestion power of 800 W; digestion process included heating to 120 ℃ keeping for 3 min, heating to 160 ℃ keeping for 5 min, and finally heating to 180 ℃ keeping for 20 min. PF power was 1 150 W, and pump speed was 50 r/min; the flow rate of atomizing gas was 0. 5 L/min, and that of plasma gas was 12. 0 L/min, detection wavelength of 182. 205-455. 403 nm. RESULTS: Results of 12 elements determination were all within standard range according to national standard substance sampling determination. The liner ranges of Cu, Mn, Mg, Cd, Zn, Fe, Ba, As, Cr and Ni were 0. 2-2. 0 mg/L, those of Se and Pb were 0. 4-4. 0 mg/L (r≥0. 999 5). The detection limits ranged 0. 1-8. 5 μg/L, and limits of quantitation were 0. 3-28. 3 μg/L. RSDs of precision tests were all lower than 1. 00％ (n=6). The average recovery rates were 88. 5％-99. 0％ (RSD were 1. 7％-4. 9％, n=6). CONCLUSIONS: The method is rapid, simple and sensitive, and it can be used for content determination of 12 trace elements in Shiquan dabu pills.

BACKGROUND: This study was undertaken to investigate the expression of hypoxia-inducible factor-1α (HIF-1α) in rat cerebral cortex and the effects of β-sodium aescinate (SA) administration after return of spontaneous circulation (ROSC).METHODS: Sixty rats were divided into three groups: SA group, injected intraperitoneally with SA instantly after ROSC; control group, injected intraperitoneally with normal saline; and sham-operated group, without cardiac arrest or SA. The cardiac arrest model was established using asphyxiation and intravenous potassium chloride. Blood was sampled 1, 6, 12, and 24 hours after ROSC. Protein and mRNA levels of HIF-1α, VEGF and EPO were detected in the cerebral cortex by immunohistochemistry and real-time RT-PCR; serum levels of NSE and S100β were determined by enzyme-linked immunosorbent assays.RESULTS: Serum S100β and NSE were signifi cantly increased in the control group versus the sham-operated group 1, 6, 12 and 24 hours after ROSC (P<0.05). Protein and mRNA levels of HIF-1α, VEGF and EPO were signifi cantly increased in the control rats (P<0.05). Serum NSE and S100β were significantly decreased in the SA group versus the control group 1, 6, 12 and 24 hours after ROSC (P<0.05). Protein and mRNA levels of HIF-1α, VEGF and EPO were signifi cantly increased in the SA group (P<0.05).CONCLUSIONS: The expression of HIF-1α is increased in rat cerebral cortex after ROSC, and SA up-regulates the expression of HIF-1α. The up-regulation of HIF-1α improves the resistance of the cortex to ischemia and hypoxia and contributes to neuroprotection, possibly because of up-regulation of EPO and VEGF expression.

Objective To study the effect of HCV receptors′sequence on virus entry based on the two-dimensional structure and via tandem expression of HCV receptors on mouse hepatocytes.Methods The construced recombinant expression vectors pCDH-hLDLR-hSR-BⅠ-hCD81-GFP, pCDH-hLDLR-hCD81-hSR-BⅠ and pCDH-hCLDN-1-hOCLN-DsRed were cotransfected into 293FT cells with package vectors.The collected recombinant lentivirus expressing hCLDN-1-hOCLN was concentrated and attacked mouse hepatocytes.The transgenic mouse hepatocytes with tandem overexpression of CLDN-1 and OCLN were established after G418-selection.The transduced cells LSCCO/Hepa1-6 and LCSCO/Hepa1-6 were sorted via flow cytometry and puro-G418-selection after recombinant lentivirus expressing hLDLR-hSR-BⅠ-hCD81 and hLDLR-hCD81-hSR-BⅠattacked Hepa1-6 respectively.The infectivity of transduced mouse hepatocytes LSCCO/Hepa1-6 and LCSCO/Hepa1-6 to HCV was analyzed via direct-infection of serum-derived virus.Furthermore, the effect of HCV receptors′sequence on virus entry was studied.Results Both LSCCO/Hepa1-6 and LCSCO/Hepa1-6 enhanced HCV-cell binding.The transduced mouse hepatocytes LSCCO/Hepa1-6 had more HCV endocytosis.Conclusion SR-BⅠhas priority over CD81 in HCV entry in the early stage.
