Objective To reveal the effect of fasting insuline(FINS) and insuline resistance(IR) in the process of benign prostatic hyperplasia(BPH). Methods One hundred and seventeen outpatients( ≥60 ys)with BPH from geriatric department were enrolled into the study. The patients were divided into groups according to their FINS and insulin resistance index (HOMA-IR). The indices of BPH, including volume of prostate ( PV ),prostate specific antigen( PSA ), international prostate symptom score (IPSS), course of BPH were analyzed in both groups. Results The PV ( [ 56. 46 ± 26. 88 ] ml vs [ 44. 84 ± 17.66 ] ml, P = 0. 017 ) and the course ( [ 18. 00 ± 6. 91 ] years vs [ 13.93 ± 7. 74 ] years, P = 0. 031 ) were significantly greater in BPH combined hyperinsulinemias(HINS) group than the BPH with normal FINS group;but we found no significant differences in the comparisons of serum PSA level or IPSS between two groups. The PV( [54. 17 ± 25.38 ] ml vs [42. 26 ±14. 15]ml,P =0. 004)and the course([ 16.58 ±7. 65] years vs [13.49 ±7. 59] years,P = 0. 036) were also significantly greater in BPH combined insuline resistance gruop than the insulin sensitivity group, again we found no significant differences in the comparisons of serum PSA level or IPSS between two groups. Conclusion FINS and IR are risk factors of progressed BPH and can promote the progress of BPH.

OBJECTIVE To investigate and analyze the risk factors,clinical characteristics and prevention countermeasures of hospital fungal incfection in old patients with malignant tumors.METHODS To adopt investigation way to review and analyze the clinical data of hospital fungal infection in 165 cases from the old patients with malignant tumors.RESULTS Among 165 cases the infection occurred predominantly in lower respiratory tract(47.2%),and with urological tract being second(19.0%).Of 165 strains of fungi from 165 patients,the first was Candida albicans(55.8%),and the second was C.tropicalis(23.0%).CONCLUSIONS The causes of hospital fungal infection in old patients with malignant tumors are highly associated with the risk factors such as primary tumor,age,radiotherapy,chemotherapy,antibiotics,hormone,invasive operation,and so on.

Objective To explore the relationship among nurses′perceptions of patient safety culture, nursing practice environment and the report barrier of nursing adverse event. Methods Totally 513 registered nurses from six hospitals in Zhengzhou were investigated with Patient Safety Culture Assessing Scale, Work Environment Questionnaire and Report Barriers Questionnaire. Results The mean scores of nurses′perceptions of patient safety culture, nursing practice environment and report barriers of nursing adverse events were (3.85±0.55), (3.84±0.53) and (2.47±0.55). The nurses′perceptions of patient safety culture were positively correlated to nursing practice environment (r=0.393,P<0.01), negatively correlated to report barriers of nursing adverse events (r=-0.372,P<0.01). The influencing factors of nurses′perceptions of patient safety culture were colleague relationship, punitive culture, allocation of medical resources, marital status, quality control, significance of report, gender and education, which could explain 33.8 percent for the variances. Conclusions The level of nurses′perceptions of patient safety culture is higher than the average level. The nursing managers should build supportive nursing practice environment and the non-punitive reporting system of nursing adverse events. Cultivate the beliefs and attitudes of nursing safety and focus on the impact of occupational stress to patient safety in order to enhance safety nursing.

Objective:To examine the adiponectin level in gingival crevicular fluid(GCF)in patients of chronic periodontitis with dia-betes mellitus type 2.Methods:20 patients of diabetes mellitus type 2 with chronic periodontitis(DM&CP),20 of periodontitis(CP) and 20 health subjects(H)were included.The periodontal indexes (SBI,PLI,PD and AL)were measured,GCF samples were quan-tified by periotron 8000,the adiponectin content in GCF was tested by adiponectin ELISA kit.The relationship between the adiponectin level in GCF and the periodontal indexes of the DM&CP patients was analyzed statistically.Results:The adiponectin level in GCF in group DM&CP was significantly lower than that in the other 2 groups(P <0.05).The adiponectin levels in GCF in group CP and H were not statistically different.The adiponectin level in GCF was negatively correlated with PD and AL(P <0.05),but had no correlation with SBI and PLI(P >0.05).Conclusion:Decrease of adiponectin in GCF may play a role in the development of DM&CP.

Objective: To analyze the influencing factors for bladder cancer in Taizhou,and to provide evidence for strengthening the prevention and treatment of bladder cancer in Taizhou. Methods : A total of 500 cases of bladder cancer diagnosed in Taizhou Hospital from 2012 to 2017 were selected as a case group,and 504 patients without tumor or urinary system diseases during the same period were selected as a control group. A structured questionnaire was used to retrospectively investigate the demographic information,occupational exposure（whether they were exposed to aromatic amine,polycyclic aromatic hydrocarbons,tobacco,tobacco smoke or heavy metals at work）,healthy behaviors and diets of the two groups one year before admission. A Logistic regression model was used to analyze the influencing factors for bladder cancer. Results : There was no significant differences in sex,age,ethnicity,education and marital status between the case group and the control group（P > 0.05）. Patients with occupational exposure history accounting for 31.60% in the case group and 24.60% in the control group,for overweight/obesity were 37.60% and 31.74%,for smoking were 55.80% and 46.23%,for high vegetable intake frequency were 43.80% and 52.58%,for high fruit intake frequency were 55.40% and 62.70%,for physical activity were 24.60% and 31.75%,respectively. The results of multivariate logistic regression analysis showed that occupational exposure（OR=1.861,95%CI：1.229-2.836）,overweight/obesity（OR=1.374,95%CI：1.021-1.863）,current smoking（OR=1.664,95%CI：1.101-2.503）and previous smoking（OR=1.454,95%CI：1.016-2.066）were the risk factors for bladder cancer. High vegetable intake frequency（OR=0.731,95%CI：0.566-0.947）,high fruit intake frequency（OR=0.659,95%CI：0.463-0.927）and vigorous physical activity（OR=0.566,95%CI：0.403-0.798）were the protective factors for bladder cancer. Conclusion Occupational exposure,overweight/obesity,current smoking,previous smoking were the risk factors for bladder cancer. High vegetables intake frequency,high fruit intake frequency and vigorous physical activity were the protective factors for bladder cancer.

Objective: To explore the correlation between serum level of high molecular weight adiponectin (HMW-ADPN) and arteriosclerosis. Methods: Clinical data of 87 middle-aged and aged people living in home, who underwent health examinations in Xiangya second hospital from Jan 2011 to Dec 2011, were collected. According to carotid-femoral pulse wave velocity (cf-PWV) = 9 m/s, they were divided into group A (cf-PWV<9 m/s, n=21) and group B (cf-PWV≥9 m/s, n=66). Blood pressure, blood lipid, blood glucose etc. were measured and compared between two groups. Results: Compared with group A, there were significant rise in blood pressure, levels of low density lipoprotein cholesterol, triglyceride and total cholesterol, and significant reduction in levels of high density lipoprotein cholesterol (HDL-C), serum total ADPN and HMW-ADPN in group B, P<0.05 or <0.01. Multiple regression analysis indicated that serum HMW-ADPN (B= - 4.469，P=0.011), total ADPN ((B= - 3.965，P=0.012), HDL-C（B= - 2.077，P=0.015) and systolic blood pressure levels (B= 0.045，P=0.045) were independent predictors of cf-PWV. Conclusion: Serum high molecular weight adiponectin and total adiponectin levels may be protective factors against arteriosclerosis. Its role in predicting occurrence and development of arteriosclerosis is worthy of further study.

Objective To explore the relationship among job satisfaction,work engagement and organizational citizenship behavior (OCB) of nurses.MethodsA total of 497 nurses in 5 tertiary level general hospitals in Zhengzhou selected by convenience sampling,were investigated by Minnesota satisfaction questionnaire,nurses' OCB scale and the Utrecht Work Engagement Scale.ResultsThe scores of job satisfaction,work engagement,OCB were (78.63±11.34),(38.31±7.78),(106.33±10.26) respectively.Nurses' job satisfaction was positively correlated with work engagement and OCB(r=0.529,0.481,P<0.01),and work engagement was positively correlated with OCB(r=0.456,P<0.01).The job satisfaction and work engagement had a positive prediction effect on OCB(changed R2=34.8%),and work engagement played a partial moderation effect between job satisfaction and OCB,the mediating effect accounted for 30.77% of the total effect.ConclusionManagers should take measures to improve job satisfaction and work engagement to promote OCB of nurses.

Objective To investigate the therapeutic effect of intensive glycemic control on patients with early diabetic nephropathy. Methods A total of 41 type 2 diabetes patients who developed microalbuminuria were divided into two groups randomly. Patients in Group A received intensive glycemic control and the blood glucose in Group B was regularly controlled. Glycemic monitoring and control were followed for 12 weeks to observe the changes of microalbuminuria in both groups; meanwhile the levels of serum lipids and coagulation indices were also recorded. Results The urine albumin excretion rate (UAER) in Group A decreased significantly from (47.91±13.86)mg/24h to (35.31±14.56)mg/24h after 12 weeks (P<0.05), and this decrease was significantly greater than that in Group B. However, Group B had no significant difference in UAER decrease [(48.93±13.32)mg/24h to (40.48±19.62)mg/24h, P>0.05]. The decrease of triglyceride (TG) and low-density lipoprotein cholesterol (LDL cholesterol), and the increase of high-density lipoprotein cholesterol (HDL cholesterol) showed no significant differences (P>0.05). And the level of plasma fibrinogen (FIB) showed no significant decrease after 12 weeks, either (P>0.05). Conclusion Intensive glycemic control reduces the level of microalbuminuria and may ameliorate the progression of early diabetic nephropathy.
