OBJECTIVE:To investigate the effects of Xuebijing injection on inflammatory factors,oxidation stress level and thrombosis risk in patients with acute non-ST elevation myocardial infarction(NSTEMI). METHODS:A total of 130 NSTEMI pa-tients selected from our hospital during May 2015-Aug. 2016 were divided into control group and observation group according to random number table,with 65 cases in each group. Control group was given routine treatment as lowering blood pressure,lower-ing lipid,anticoagulation and antiplatelet. Observation group was additionally given Xuebijing injection 50 mL,ivgtt,q12 h,on the basis of control group. Both groups were treated for a week. The levels of inflammatory cytokines(TNF-α ,IL-6,IL-10, hs-CRP),SOD,MDA,MMP-9,platelet aggregation rate and fibrinogen were observed in 2 groups before and after treatment. The treatment course,the occurrence of MACE and bleeding event were also recorded. RESULTS:Before treatment,there was no statistical significance in the levels of inflammatory factors,SOD,MDA,MMP-9,platelet aggregation rate or fibrinogen between 2 groups(P>0.05). After treatment,the levels of TNF-α,IL-6,hs-CRP,platelet aggregation rate or fibrinogen in 2 groups were decreased significantly,while the level of IL-10 was increased significantly;the improvement of above indexes in observation group was significantly better than control group. The levels of SOD and MMP-9 in 2 groups were increased significantly,while the level of MDA was decreased significantly. The level of SOD in observation group was significantly higher than control group, while the level of MDA was significantly lower than control group,but the level of MMP-9 was significantly lower than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of MACE (16.92% vs. 20.00%)or bleeding event(4.62% vs. 7.69%)between 2 groups(P>0.05). CONCLUSIONS:Xuebijing injection shows signifi-cant therapeutic efficacy for NSTEMI,effectively inhibits inflammation,and oxidative stress and reduces the risk of thrombosis with good safety.

Objective To investigate the therapeutic effect of ectopic pregnancy prescription,mifepristone and methotrexate in the treatment of refractory tubal pregnancy.Methods 100 cases of refractory tubal pregnancy from January 2015 to December 2016 in our hospital,according to randomly divided into Chinese and western medicine group(ectopic pregnancy treatment prescription+mifepristone+methotrexate)and western medicine group(mifepristone and methotrexate)50 cases,compared two methods of treatment effect.Results After treatment,the two groups of patients with β-HCG level,ectopic pregnancy mass diameter showed a significant decrease,beta-HCG,ectopic pregnancy mass of Chinese and western medicine group were lower than the diameter of the western medicine group in the treatment of 7,10,14 days,the difference was statistically significant(P<0.05); The success rate of Chinese and western medicine group was 92.00％,which was higher than that of western medicine group(84.00％),but the difference was not statistically significant,failure of conservative treatment of patients were transferred to open surgery.In Chinese and western medicine group,the β-HCG value of blood beta was completely recovered and the disappearance time of ectopic pregnancy was significantly lower than that of western medicine group,and the difference was statistically significant(P<0.05).Conclusion Ectopic pregnancy prescription combined with mifepristone and methotrexate in the treatment of refractory patients with tubal pregnancy can accelerate the β-HCG level,ectopic pregnancy mass diameter reduced,can significantly shorten the treatment time.

Results The observation group was superior to the control group in treatment com-pliance, pulmonary function examination and the control results of asthma. Conclusions Specific im-munotherapy of hypoglossis allergen combined with modified nursing method can increase treatment com-pliance of children and lead to better results.

Objective To investigate awareness about tuberculosis (TB) prevention and treatment and influence of professional training on TB detection among health-care workers (HCWs) in general hospitals.Methods In total,750 HCWs were trained for TB-related knowledge for eight class-hours in a two-day course in three general hospitals,and 20 HCWs from each of the three hospitals classified as grade 3A and grade 2A in urban Beijing and grade B at suburban Beijing,respectively,were interviewed with questionnaire designed to understand their awareness about TB prevention policy,epidemiology,diagnosis and treatment,and to evaluate effectiveness of the training,respectively.All the trainees responded before and after the training,with a hundred percent of response rate.TB diagnosis and reporting one year before training in the three hospitals were compared to those one year after it.Results Scores of knowledge about TB diagnosis and treatment averaged 64-80 for HCWs before training,with statistically significant difference among three hospital (F = 5.984,P ＜ 0.01).Scores increased after training,but without significant difference from those before it (P ＞ 0.05).Awareness of TB prevention policy,regulations and epidemiology was insufficient in most HCWs of those hospitals,with lowest and highest average scores of 38.3 and 71.7 before training,respectively,but scores increased significantly after training (P ＜ 0.01).Proportion of TB diagnosis with chest roentgenograph at grades 3A and 2A hospitals was significantly higher one month,three months and six months after training,as compared to that at suburban hospitals (P ＜0.01).There was significant decrease (P ＜ 0.01) in proportion of chest roentgenograph at respiratory departments in hospitals grade 3A and grade 2A after training.There was no significant difference in reporting of pulmonary TB and positive sputum smear (P ＞ 0.05) before and after training.Conclusions HCWs in general hospitals had experience and capacity in diagnosis and treatment of pulmonary TB,but their knowledge of TB prevention policy and epidemiology was insufficient.Their ability in finding and reporting TB can not been improved with short-term training.

Objective To identify and analyze the species of vaginal lactobacilli between patients with bacterial vaginosis (BV) and healthy women at childbearing age in Inner Mongolia. Methods From Jun. 2008 to Dec. 2008, 203 Mongolian healthy women, 74 Han healthy women and 102 Mongolian patients with BV from 3 pastoral areas were enrolled in this study. Isolation and culture of lactobacilli from vaginal wall were performed by modified culture medium. DNA of lactobacilli were extracted and sequenced. H2O2 were detected by TMB-HRP-MRS. Results(1)The rate of lactobacilli identification were 76.8%(156/203) in Mongolian healthy women and 21.6% (22/102) in Mongolian patients with BV, which reached statistical difference(P＜0.01).Lactobacilli identification in Han healthy women [82.4%(61/74)] did not show significant difference with that of Mongolian healthy women (P＞0.05). (2) The total of 193 strains and 11 species of Lactobacillus were detected in 203 Mongolian healthy women. Meanwhile,22 strains and 4 species of Lactobacillus were found in 102 Mongolian BV cases.(3)The rate of H2O2 generating Lactobacilli was 27.3% (6/22) in Mongolian BV patients and 75.7% (56/74)in Mongolian healthy women, which showed statistical difference(P＜0.05). Conclusions The rate of Lactobacillus was not related with the race of women in pastoral area in Inner Mongolian. The amount of lactobacilli and H2O2 generating Lactobacilli in the vagina of BV patients was remarkably lower than those of healthy women at childbearing age.

Telomere maintenance plays a critical role in cancer progression.Approximately 85% human cancer cells maintain their telomere length through activation of telomerase.Other 15%of cancers maintain telomere length independently of telom-erase by alternative lengthening of telomeres (ALT)pathway. Both events are equally important for telomere length mainte-nance of cancer cells.Human telomere consists of a series of G rich DNA sequences,which could form G-quadruplex.The for-mation of this structure can block the extension of telomeres by telomerase or ALT,resulting in cancer cell death.Thereby,G-quadruplex has been one of the focuses of anticancer therapy in recent years.This review focuses on the latest progress of G-quadruplex stabilizers.
