BACKGROUND:Pulmonary hypertension stil lacks effective treatment measures. The effects of alprostadil in the treatment of pulmonary hypertension remain controversial. OBJECTIVE:To observe the effect of alprostadil in the treatment of pulmonary hypertension induced by chronic hypoxia. METHODS:24 experimental rats were randomly and evenly divided into control group, model group, and treatment group. The rats of model and treatment groups were fed in the hypoxic box to establish the animal model of pulmonary hypertension, and the rats of control group were fed in the normal air. After pulmonary hypertension induction, rats from the treatment group were intraperitonealy administered alprostadil injection (5 μg/kg per day) for 4 consecutive weeks. RESULTS AND CONCLUSION:Compared with the model group, the mean pulmonary artery pressure, right ventricular systolic pressure, pulmonary vascular thickness, size of blood vessels and alveolar wal thickness of rats in the treatment group were obviously decreased. The results suggest that alprostadil can decrease pulmonary artery pressure and prevent lung injury.

Objective To formulate job evaluation index system for clinical nurse specialist in comprehensive children′s hospital. Methods A total of 19 experts were consulted by two-round Delphi method to ensure the item of index system, the order and weight of each index was determined by hierarchy analysis. Results The evaluation index system included 5 level-1 dimensions, 13 level-2 dimensions and 30 level-3 items. The authority of the expert advisory coefficient was 0.84, determine coefficient was 0.91, familiarity cofficient was 0.77. The coordination coefficient of one, two, three indexes were 0.44, 0.52, 0.51, with statistical significance (P < 0. 05). Conclusions The job evaluation index system is reliable and valid, which can provide basis on job management.

Objective To investigate the efficacy of sophocarpine in rats with alcoholic liver disease and its effects on the expression of tumor necrosis factor (TNF)-α,interleukin (IL)-6 and transforming growth factor (TGF)-β1.Methods A total of 48 male Sprague-Dawley adult rats were evenly divided into healthy control group,model group,prevention group and treatment group.The rats in the healthy control group were gavaged with 0.9％NaCl every day for 12 weeks.The rats in the model group,prevention group and treatment group were gavaged with alcohol for 12 weeks to establish the model.The prevention group was injected with 20 mg · kg1 · d1 sophocarpine for 12 weeks.Since the fifth week,the treatment group was continuously injected with 20 mg · kg1 · d-1 sophocarpine for eight weeks.The histological changes were evaluated.The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase ( AST ), alkaline phosphatase (AKP),triglyceride (TG) and total cholesterol (TC) were examined.And the expression of TNF-α,IL-6 and TGF-β1 in liver tissue at mRNA and protein level were detected with immunohistochemistry and real-time polymerase chain reaction (PCR) assay.Comparison among groups was perform with single factor analysis of variance,pairwise comparisons with least significant difference method (LSD method),ranked data with Kruskal-Wallis H-test and multiple pairwise comparison with Nemenyi test.Results Compared with model group,hepatic steatosis and inflammatory cell infiltration were significantly improved in the treatment group and prevention group.The levels of ALT (41.40 U/L± 10.53 U/L and 40.75 U/L±6.94 U/L vs 58.37 U/I±5.35 U/L),AST(121.60 U/L±16.24 U/L and 109.50 U/L±9.23 U/L vs 156.63 U/L±32.47 U/L),AKP(114.88 U/L±40.37 U/L and 112.60 U/L±44.34 U/L vs 161.75 U/L±28.95 U/L),TG (4.19 mmol/L±0.99 mmol/L and 2.69 mmol/L± 1.35 mmol/L vs 4.50 mmol/L±0.99 mmol/L) and TC (1.48 mmol/L±0.28 mmol/L and 1.43 mmol/L±0.19 mmol/L vs 1.67 mmol/L±0.20 mmol/L) significantly decreased and the difference was statistically significant ( all P＜0.05).The expression of TNF-α,IL-6 and TGF-β1 at mRNA and protein level in liver tissue of model group were significantly higher than those of healthy control group,prevention group and treatment group.After treated with sophocarpine,the expression of TNF-α(mRNA:1.36 ± 0.08,1.16 ± 0.05 ; protein:3.38 ％ ± 0.82 ％,1.74 ％ ± 0.65 ％ ),IL-6 (mRNA:1.51 ± 0.05,1.39 ± 0.02; protein:5.89％ ± 0.96％,4.26％ ± 0.53％) and TGF-β1 (mRNA:1.39±0.04,1.37±0.02; protein:4.27％ ±0.97％,2.11％ ±0.83％) of treatment group and prevention group at mRNA and protein level significantly lower than those of model group (mRNA:1.81±0.16,1.95 ±0.13,1.84±0.22; protein:5.82％ ± 1.21％,7.63％ ±1.03％,5.33％± 1.12％) and the difference was statistically significant (all P＜0.01).Conclusion Sophocarpine significantly alleviates alcohol induced liver injury in rats,improves liver steatosis and inflammatory reaction degree,which may be related with the downregulation of TNF-α,TGF-β1 and IL-6 expression in liver tissue of ALD rats.

Objective To investigate the effect of comprehensive intervention led by nursing staffers on the drug compliance in patients with hepatitis B virus-related hepatocellular carcinoma (HCC) after receiving transcatheter arterial chemoembolization (TACE) treatment.Methods By using random sampling method,a total of 96 patients with hepatitis B virus-associated HCC,who had been treated with TACE and had taken nucleotide analogue drug for one month in the interventional department of a certain grade Ⅲ tumor hospital,were enrolled in this study.Under the premise of informed consent,comprehensive intervention,which was led by nursing staffers and was participated by both doctors and nurses,was conducted.Results After comprehensive intervention,the average score of drug compliance was (93.670±6.046) points,while the pre-intervention average score of drug compliance was (82.040±10.024) points,the difference between the two was statistically significant (P＜0.05).The ratio of patients who showed good drug compliance changed from pre-intervention 62.4％ to post-prevention 97.8％(P＜0.05).The post-prevention of patients,whose hepatitis B virus deoxyribonucleic acid (HBVDNA) level was within the normal range,was 45.16％,which was highcr than the pre-intervention ratio of 15.05％,the difference between the two was statistically significant (P＜0.05).Conclusion The comprehensive intervention led by nursing staffers can effectively improve the drug compliance in patients with hepatitis B virus-associated HCC after receiving TACE,and can reliably control serum HBVDNA level as well.
