OBJECTIVE:To observe the clinical efficacy and safety of Enalapril folic acid tablet combined with Shenkang injec-tion in the treatment of hypertensive nephropathy. METHODS:90 patients with hypertensive nephropathy were randomly divided in-to control group and observation group. All patients were given anti-infection,regulating electrolyte balance,supplying amino acids and other conventional treatment. Based on it,control group was orally given Maleic acid enalaprilat folic acid tablet 1 tablet in the morning,once a day;observation group was additionally given 100 ml Shenkang injection adding into 300 ml 10% Glucose injec-tion by intravenous infusion,20-30 drops/min,once a day. The treatment course for both groups was 4 weeks. The clinical effica-cy,and clearance rate of creatinine(Ccr),serum creatinine (Scr),morning urine test urine protein (Up)/urine creatinine (Ucr), serum malondialdehyde(MDA),superoxide dismutase(SOD),total antioxidant capacity(T-AOC)before and after treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,the Ccr,SOD and T-AOC in 2 groups were significantly higher than before,and observation group was higher than control group,Scr and MDA were significant-ly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). Morning urine test Up/Ucr,systolic blood pressure and diastolic blood pressure were significantly lower than before,and the differ-ences were statistically significant(P<0.05),however,there was no significant difference between 2 groups(P>0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Based on the conventional treat-ment,Enalapril folic acid tablet combined with Shenkang injection has better efficacy than only Enalapril folic acid tablet in the treatment of hypertensive nephropathy,with similar safety.

Objective To explore the value of angiographic diagnosis and interventional therapy of severe gastrointestinal bleeding.Methods 33 patients in a critically ill state(1000ml of bleeding greater than alimentary canal),who could not or were not willing to go fibre gastroscope/intestines ytterbium checks,were diagnosed by selectivie or surpass-selectivie stomach-bowel angiography,and embolismed or poured into by the surpass-selection artery art after the bleeding artery definiting at the same time.Results The selective stomach-bowel artery radiography group identified 27 patients site of bleeding,the masculine rate was 82%.The surpass-selectivie stomach-bowel artery radiography group identified 31 patients site of bleeding,the masculine rate was 94%.2 patients had no abnormality,26 patients were cured by the embolism,7 patients were treated successfully by pouring into the pharmaceuticals.Among them 8 patients were bleeding again,4 patients were cured through the surgical operation without complication.Conclusions DSA surpass-selectivie stomach-bowel artery radiography can define the site of severe gastrointestinal bleeding and raise the hemorrhage kitchen range recall rate,the embolism can successfully control the bleeding.Throughout the pouring into the pharmaceuticals,those who can't be treated by embolism can save time for the surgical operation,make part of patient cure further gaining time for the surgical operation.

To investigate the effect of autoimmune regulator (AIRE) on phagocytic clearance of apoptotic cells, a recombinant expression vector containing full-length human AIRE cDNA was transfected into 16HBE cells. After incubation with transfected 16HBE cells, engulfment of apoptotic HL-60 cells induced by camptothecin was detected by myeloperoxidase (MPO) staining. The change in the expression of Rac 1 in transfected 16HBE cells was determined by RT-PCR and Western blotting. The results showed that the phagocytosis percentage of the experimental group, the mock transfection group and the negative control group (non-apoptotic cells) was (25.50+/-3.67)%, (6.25+/-1.58)% and (1.0+/-0.67)%, respectively. Moreover, the expressions of Rac 1 mRNA and protein were up-regulated in AIRE-transfected 16HBE cells, suggesting that AIRE may function as a regulator in the phagocytic clearance of apoptotic cells by promoting the expression of Rac 1.

Objective To explore the value of E-flow technique in ultrasound examination of fetal pulmonary vein.Methods The pulmonary veins of 332 fetus were examined using lungs as acoustic window by two-dimensional echocardiography(2DE), color Doppler flow imaging (CDFI) and E-flow.Visualization ratios of the three methods were compared.Results The fetal pulmonary veins were displayed as following:7 cases were showed by 2DE,49 cases by CDFI and 73 cases by E-flow among 118 cases during 12 - 22 gestational weeks.The visualization ratio of E-flow was higher than that of the other two methods (P ＜0.001).Fourty-one cases were showed by 2DE, 171 cases by CDFI and 177 cases by E-flow among 214 cases during 23 - 40 gestational weeks.The visualization ratios of E-flow and CDFI were higher than that of 2DE (P ＜ 0.001).The visualization ratio of E-flow and CDFI has no distinct differrence (P ＞ 0.0167).Conclusions E-flow was sensitive to pulmonary vein blood flow and better than 2DE and CDFI in early stage of the second trimester.

Objective To acknowledge the quality of life (QOL) in patients after lung transplantation and to explore related factors. Methods A cross- sectional study design and a convenience sampling were performed in this research. Totally 30 patients after lung transplantation were investigated. The questionnaires which used to explore the quality of life were Short Form 36 Health Survey Questionnaires (SF-36) and Revised Airways Questionnaires 20 (AQ20-R). Related state were surveyed by questionnaires consisted of demographic questionnaires, Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and Medical Coping Mode Questionnaires (MCMQ). Statistical analysis was performed by SPSS 20.0 software. Correlation analysis and multivariate analysis were performed using Pearson linear correlation analysis and multi-linear regression. Results The scores among the 8 dimensions of SF-36 were(34.48±16.73)-( 71.63±22.83), lower than those of norms(Z=-9.684--2.817, P<0.05 or 0.01). Somatic pain scored the highest (71.63±22.83), while physiological function scored the lowest (34.48±16.73). The mean score of AQ20-R was 7.93±5.21. The major two problems that manifested QOL were: uncomfortable feeling of lung caused by strong scent, smog or perfume, exhausted feeling after having a cold. The mean scores of SAS and SDS were 44.33±9.33,48.05±9.80, higher than those of norms, which were 33.80 ± 5.90, 41.88 ± 10.57 (t=6.1833, 3.4458, P < 0.01). The scores among the 3 dimensions of MCMQ were 8.93 ± 2.08, 16.10 ± 2.28, 3.63 ± 1.33 and the differences were significant in 3 dimensions compared with those norms, which were 19.48±3.81, 14.44±2.97, 8.81±3.17(t=-27.7281, 3.9885,-21.3878, P<0.01). Conclusions In SF-36, role-physical of patients after lung transplantation was the worst dimension, while bodily pain was the best dimension of QOL. The QOL of patients after lung transplantation were almost worse than normal people. The related factors of QOL in patients after lung transplantation maybe:anxiety, depression and medical coping style.

Objective To explore the anti-tumor effect and the influence of antitumor immunity of PD-L1/PD-1 blocked by PD-1 antibody combined with cisplatin. Methods Tumor models were established by injecting TC-1 cells into C57BL/6 mice, and the mice were divided into four groups (n = 4). The tumor growth curves and survival curves were drawn to observe the anti-tumor effect. The tumors were then removed; and the PD-L1 and CD8+ T cells were analyzed by immunohistochemical method. Results The anti-tumor effect was greater in the cisplatin group , PD-1 antibody group , and PD-1 antibody plus cisplatin group than in the control group (P < 0.05). Expression of PD-L1 in the tumor tissues was markedly increased in the cisplatin group and it was obviously decreased in the combination group (P < 0.05). CD8+ T cells decreased in the cisplatin group; and expression of CD8+ T cells was significantly increased the combination group (P < 0.05). Conclusion The anti-tumor effect and anti-tumor immunity of cisplatin are enhanced by blocking PD-L1/PD-1 pathway with PD-1 antibody.
