Objective To explore the effects of passive smoking on vascular endothelial function in office women.Methods Totally,94 healthy office women volunteers from urban(36 women)and townships or towns(58 women)were divided into three groups based on the extent of their daily exposure to passive smoking,group A exposed to one to eight cigarettes,group B exposed to nine to 15 cigarettes,and group C exposed to more than 15 cigarettes,respectively,with 20 healthy young women without exposure to passive smoking as controls.Internal diameter of the brachial artery Was measured by color Doppler ultrasound scanning for each of the participants and its changes were observed before and after congestive reaction of the brachial artery test and nitroglycerin test.Results Thirteen of 36 office women from urban and 38 of 58 from townships or towns exposed to passive smoking of more than eight cigarettes daily,with chi-square of 7.74,P=0.0054.The brachial artery in groups A,B and C dilated less than that in the controls did.The brachial artery in group C dilated less than that in the groups A and B did.Conclusion Passive smoking could damage vascular endothelial dilatation function in office women.

Objective To explore the clinical values of the modified thoracic drainage devices that were applied in treatment of primary spontaneous pneumothorax patients who underwent single-port video-assisted thoracoscopic surgery. Methods Clinical data of 82 primary spontaneous pneumothorax patients who underwent single-port video-assisted thoracoscopic lung wedge resection and pleurodesis from January 1st, 2015 to August 31st, 2016 was analyzed retrospectively. These patients, according to the thoracic drainage devices, were divided into traditional group (Group A, n = 42) or modified group (Group B, n = 40). These statistical data, including duration of thoracic drainage, lengths of hospital stay, duration of using antibiotic, amounts of pleural drainage, scales of pain, and complications of the two groups of patients in postoperative stage, were compared. Results There was no significant differences (P > 0.05) in volumes of thoracic drainage while there were significant differences (P < 0.05) in duration of thoracic drainage, lengths of hospital stay, duration of using antibiotic, scales of pain, and complications in postoperative stage between the two groups. And patients in group B had shorter time of thoracic drainage, hospital stay, and using antibiotic, lower scales of pain and rates of complications when compared with group A. Conclusion There are some clinical values of application of modified thoracic drainage devices in treatment of primary spontaneous pneumothorax underwent single-port video-assisted thoracoscopic surgery, because of it could give the patients fast recovery and made the operations simpler.

Objective The staffs of biosafety level 3 laboratories (BSL-3) face with the stress of handling highly pathogenic microbs and special laboratory environment.The job stress may result in accidents in the laboratory as negative factor for the risk control.The research may provide support for the control of risk in biosafety laboratories.Methods In order to assess the job stress in the staff in BSL-3 laboratory, we modified “the Chinese simple job stress questionnaire”based on the theory of the JDC mode and ERI mode, and an investigation was carried out.The present study included the staffs (87 employees) from six BSL-3 laboratories located in five provinces ( Shanghai, Zhejiang, Jiangsu, Fujian and Wuhan) .Results Analysis of the data indicates that variables of age, working years, job duties, manipulating of animals, type of microorganisms and transmission route have a significant influence on the level of job stress in BSL-3 laboratory.Conclusion The BSL-3 laboratory staff in higher stress level have the characteristicses:20-39 years old, short work years, regular staff, operating on air-borne microbiology, manipulating of animals and operating on one more microbiology.

Objective    To investigate the safety of endoscopic thoracic sympathicotomy in the treatment of primary hyperhidrosis based on ambulatory surgery mode. Methods    Retrospective analysis was performed on the clinical data of 158 patients with primary hyperhidrosis who received endoscopic thoracic sympathicotomy in the Affiliated Hospital of Zunyi Medical University from January 2019 to March 2021. There were 68 (43.2%) males and 90 (56.8%) females with an average age of 14-33 (20.5±3.1) years. The basic information of the patients, operation time, intraoperative blood loss, postoperative pain score, hospitalization expenses and postoperative complications were observed and recorded. Results    All surgeries were successfully completed and the patients were discharged as planned. The operation time was 41.8±13.9 min, the intraoperative blood loss was 10.5±7.3 mL, the postoperative anesthesia recovery time was 15.0±5.9 min, and the pain score was 3.0±0.9 points. The total length of hospitalization was 1.6±1.0 days. The total postoperative expenses were 9 471.7±1 698.9 yuan. Pneumothorax occurred after the operation in 3 patients. Telephone follow-up on the 30th day after the operation showed no recurrence of sweaty hands, pneumothorax or rapid heart rate, and no serious complications or death related to the day operation within 30 days after the operation. Conclusion    Endoscopic thoracic sympathicotomy based on ambulatory surgery mode is safe and effective in the treatment of primary hyperhidrosis.
