The paper introduced the organization culture building of a private hospital, in creating the Aikang hospital as your home culture and Aikang values for building a harmonious workplace for the hospital. The management system reform features the separation between regulations and management,building of the supporting system and operating system, for better quality of care with advanced management practice. The social rewards feature great efforts in supporting the disadvantageous population, and undertaking public health service and charity activities. These care and love to the community help the hospital to fulfill its social responsibilities.

Objective To investigate a wide range of uterine cervical cancer after hysterectomy for lower urinary tract urinary dynamics characteristics.Methods Cervical cancer Ib Ⅱ a via ablominal extensive hysterectomy in 25 cases were analyzed retrospectively,which had the type of operation in 7 cases,type Ⅲ Procedures for 18 cases,respectively,at 1 month after operation and 1 urethral urodynamic studies.Results The patients showed varying degrees of voiding dysfunction and urine storage dysfunction,maximum urinary flow rate decreased significantly (10.01 ml/min),the average decrease in urinary flow rate(6.44ml/min),voiding time 77.63s,residual urine volume 103.16ml,maximum bladder capacity 288.68ml,postoperative beard had the aid of abdominal pressure urination.Conclusion Extensive hysterectomy can occur after different degree of voiding dysfunction and urine storage dysfunction,and duration is longer,the main manifestation of impaired detrusor function,bladder sensory dysfunction,urethral dynamics can contribute to early diagnosis,early treatment,to prevent serious complications of the urinary system.

Objective To evaluate the levels of serum organochlorine pesticide residues in breast cancer patients and benign breast disease patients from Tangshan areas. Methods One hundred fifty-eight breast cancer patients and 129 benign breast disease patients from two districts of TangShan were entrolled in the study. The levels of serum organochlorine pesticides ( DDTs and HCHs) were detected through gas chromatography/electron capture. Spearman's rank correlation was used between age, BMI and the level of serum organochlorine pesticide residues in patients. Results The serum levels of a-HCH, p-HCH and PP'-DDE between breast cancer patients and benign breast disease patients were statistically different(P <0. 05). The serum levels of p-HCH and PP'-DDE were positively correlated with age and BMI in both groups, with correlation coefficients of 0. 272 and 0. 330 for age and 0. 207 and 0. 313 for BMI in the breast cancer patients,as well as correltion coefficients of 0. 339 and 0. 260 for age and 0. 227 and 0. 209 for BMI in the benign breast disease patients. Conclusions The levels of organochlorine pesticide residues in serum in breast cancer patients were higher than those in benign breast disease patients and were positively correlated with age and BMI. The results offer more information to the pathogenesis, prevention and control measures of breast cancer.

Objective To investigate the recurrence and influence factors of spontaneous pneumothorax in patients after thoracoscope surgery. Methods From March 2009 to March 2011,218 patients with spontaneous pneumothorax after thoracoscope surgery in our hospital were surveyed by the self-made general data questionnaire. The clinical data were analyzed by descriptive statistics and binary classification logistic regression analysis of SPSS 19. 0 to find out the infection influential factors of spontaneous pneumothorax for patients after thoraco-scope surgery in order to provide reference basis for reducing postoperative recurrence. Results The recurrence rate of spontaneous pneumo-thorax was 5. 05%(11/218). Multiple logistic regression analysis showed that recurrent pneumothorax ( OR=2. 432,P=0. 000) and multi-ple pulmonary bulla (OR=1. 918,P=0. 000) were the risk factors of spontaneous pneumothorax for patients after thoracoscope surgery. Conclusion The recurrence rate of spontaneous pneumothorax is high,we should strengthen the management of high-risk population and im-prove the prognosis of patients.
