Objective To compare the number of endothelial progenitor cells (EPCs) from peripheral blood in patients with acute myocardial infarction of young man and healthy man.Methods Eighteen young men (18 ～50 years old) with acute myocardial infarction (AMI) who were admitted at the First Affiliated Hospital of Dalian Medical University from June 2010 to April 2011 in young man were enrolled,aged (65 ～ 85 years old) men with acute myocardial infarction in 18 cases,within 24 hours of onset collected blood 2 ml.Ten cases of healthy young men (30 ～50 years old) were used as control group,fasting venous blood 2 ml.A volume (400 μl) of blood was taken to red blood cell lysis buffer hemolysis labeled with vascular endothelial growth factor (VEGF),CD34,and CD133 antibodies,and then analyzed with flow cytometry.Results The number of EPCs in peripheral blood was measured in young male AMI group.The number of EPCs in peripheral blood was (0.58 ±0.83)％ in older men.The number of EPCs in peripheral blood of AMI group was (0.04 ± 0.03) ％.For healthy controls,the number of EPCs was (0.02 ± 0.02)％.The number of EPCs was significantly higher in AMI patients compared to control group (P ＜ 0.05).However,for AMI group,the increased number of EPCs in young men was significantly greater than young female (P ＜0.01).Conclusions The number of EPCs in peripheral blood in young man AMI patients is significantly increased within 24 hours.

Objective To observe the therapeutic effect of Wenyang Huayu Sanjie Decoction ( WHSD) for the treatment of adenomyosis with the syndrome of blood deficiency and cold stagnation. Methods Seventy qualified patients were evenly randomized into observation group and control group. The control group was treated with Mirena intrauterine contraceptive device, and the observation group was treated with WHSD ( composed of Danggui Sini San, Wuzhuyu Shengjiang Tang, Shixiao San and Rhizoma Sparganii, Rhizoma Curcumae). The clinical outcomes included the menstrual blood volume, menstrual cycle, menstruation, degrees of dysmenorrhea, uterine volume, and serum CA125 level in the two groups before treatment and 3, 6 months after treatment. Results ( 1) After treatment for 6 months, the total effective rate of the observation group was 94.29%, significantly higher than 85.71% in the control group ( P<0.05). ( 2) After treatment, dysmenorrheal degrees, menstrual blood volume, menstrual cycle, menstruation, uterine volume, and serum CA125 level were improved in both groups ( P<0.05) , and the observation group had better effect on relieving dysmenorrhea, improving menstruation, and decreasing CA125 level than the control group ( P<0.05). ( 3) No obvious adverse reaction was found in the observation group, but most of the cases in the control group had menstrual disorder such as vaginal irregular bleeding and prolongation of menstruation. Conclusion WHSD has certain therapeutic effect on adenomyosis with the syndrome of blood deficiency and cold stagnation, and can also obviously improve the quality of life of the patients.

Objective To observe the clinical efficacy of Wenjing Shexue Recipe ( WSR) in treating polycystic ovarian syndrome ( PCOS) with liver-kidney deficiency, and to explore the possible therapeutic mechanism. Methods Seventy-four PCOS patients were randomized into observation group ( N=38) and control group ( N=36). The observation group was given oral use of WSR and the control group was treated with Ethinylestradiol and Cyproterone Acetate Tablets orally. Both groups received treatment for 6 months, and were followed up for 3 moths after drug withdrawal. After treatment, the therapeulic effect was evaluated , and the changes of body mass index ( BMI) , hairiness. acne, and sexual hormone levels were monitored before and after treatment. Results ( 1) The total effective rate of the observation gorup was 92.11% and that of the control group was 75.00%, the difference being significant ( P<0.05). ( 2) After treatment for 6 months, body mass index (BMI), the scores of hairiness and acne, and serum levels of testosterone (T) and luteotrophic hormone (LH) were decreased in the observation group (P<0.05 compared with those before treatment). The control group had lower scores of hairiness and acne and serum levels of T and LH than those before treatment ( P<0.05) , but BMI showed no obvious decrease (P>0.05) . The results of follow-up showed that BMI, the scores of hairiness and acne, and serum levels of T and LH were still lower in the observation group than those before treatment (P<0.05), but the above indexes except acne scores were increased in the control group (P>0.05 compared with those before treatment) and were higher than those of the observation group (P<0.05). Conclusion WSR exerts better effect for the treatment of PCOS with liver-kidney deficiency than Ethinylestradiol and Cyproterone Acetate Tablets, and the possible mechanism is probably related with the regulation of endocrine disturbance by decreasing serum T and LH levels.

Objective To investigate the level and influencing factors of nurses' professional growth,in order to provide evidence for promoting the satisfaction degree of nurses with their career and reducing nursing turnover rate.Methods A random sample of 526 clinical nurses from 6 third-level and firstclass hospitals in Tianjin were investigated with Career Growth Scale.Resalts The score of chnical nurses' professional growth averages was (2.44±0.53) points.Single factor analysis found that working purpose,the work-ing years and sex affected the total score of career growth and the score of each dimension statistically.Multiple linear regression analysis showed that working purpose was the greatest impact on the degree of the career growth score among influencing factors,followed by the working years and sex.Conclusions Nurses' professional growth is on the average level.All relevant departments should strengthen the construction of professional nurse,improve the promotion and salary system to strengthen the nurses' career growth,in order to enhance the nurse's career satisfaction,reduce the nurse turnover rate.

Objective To monitor the resistance of Streptococcus pneumoniae following the 2004 in Qingdao area, and to provide a reasonable basis for clinical application of antimicrobial agents. Methods Collecting respiratory tract, blood, cerebrospinal fluid and other specimens from out-patient and in-patients of some hospital in Qingdao from January 2005 to December 2008. According to the recommendation of NCCLS, antibiotic resistance analysis of 11 kinds of antibiotic to the isolated 231 Streptococcus pneumoniae by micro-agar dilution method, and analysis resistance trends and age differences. Results The results showed that the rate of Streptococcus pneumoniae not sensitive to penicillin is 23. 38% (PRSP: 9.52% , PISP: 13. 85% ) , resistant to cefotaxime is 9. 96% (23/231), resistant to amoxicillin is 12. 55% , resistant to erythromycin is 90. 48% (209/231). PRSP rate of patients younger than 14 years of age 27. 91% (12/43), significantly higher than that of the PRSP rate of adults 5. 38% (10/186). Conclusion The rate of resistant to penicillin Streptococcus pneumoniae increased significantly from 2004, and an increasing trend year by year, the resistance of Streptococcus pneumoniae is also a rising trend year by year. For patients infected low penicillin-resistant Streptococcus pneumoniae in this region, cefotaxime, amoxicillin are preferred drugs.

Objective: To investigate the roles of Bcl-xl and Bcl-xs in the development and progression of endometrial carcinoma, and to explore their correlation.Methods: The expression of Bcl-xl and Bcl-xs in 32 cases of endometrial carci-noma, 12 cases of endometrial atypical hyperplasia, 6 cases of endometrial simple hyperplasia and 10 cases of normal en-dometrial tissues were examined by RT-PCR and Western-blot.Results: The expression of Bcl-xl mRNA and protein was significantly higher in endometrial cancer tissues than in normal endometrial tissues (P<0.05), and was statistically associat-ed with the pathological stage of endometrial carcinoma.(F=5.33, P=0.02).The expression of Bcl-xs mRNA and protein in atypical endometrial hyperplasia and endometrial carcinoma tissues were significantlly lower than that in normal endometri-al tissues (P<0.05), which was also associated with clinical stage and lymph node metastasis of endometrial carcinoma (P<0.05).The expression of Bcl-xl was negatively correlated with the expression of Bcl-xs in different endometrial tissues (r=-0.76).Conclusion: The abnormal expression of Bcl-xs and Bcl-xl was a factor for the pathogenesis and development of endometrial carcinoma.The negative correlation between Bcl-xl and Bcl-xs in different endometrial tissues as well as their relative expression ratio may have certain impact on the genesis of endornetrial cancer.
