Objective To compare the advantages and disadvantages of uniportal video-assisted thoracic surgery(uniportal-VATS)and three portal VATS in treatment of benign pulmonary diseases. Methods The clinical data of 66 patients with benign pulmonary disease treated by VAST from June 2015 to October 2016 were retrospec-tively analyzed. The patients were divided into two groups according to the specific operation. There were 32 patients (18 males and 14 females)in uniportal-VATS group. There were 34 patients(18 males and 16 females)in three portal VATS group. The operative time ,intraoperative blood loss ,thoracic drainage volume at 24 h after opera-tion,incision length,and the time of postoperative drainage of thoracic cavity,postoperative third day pain score and complication rate were compared between the two groups. Results The patients in the experimental and the control groups were successfully operated according to the scheduled protocol. No thoracotomy was performed. There was no statistical difference in the volume of blood loss,the volume of pleural drainage after 24 hours,the time of postoperative drainage of thoracic cavity ,the length of hospital stays and postoperative complications in uni-portal-VATS group and three portal VATS group(P>0.05). The pain score and postoperative third day pain score of the uniportal-VATS group was better than that of the three portal VATS group(P<0.05),but the operation time of the uniportal-VATS group was longer than that of the three portal VATS group(P<0.05). Conclusion Uniportal-VATS is safe and feasible for the treatment of benign lung diseases. It is more minimally invasive and beautiful than traditional three-hole thoracoscopic surgery. It is worthy of promotion and has broad prospects.

Objective To evaluate food intolerance sensitivity among 2962 health check-up receivers from the First Hospital of China Medical University.Methods Serum samples of 2962 adults were collected from January 2008 to June 2010.Serum allergen-specific IgG antibodies of 14 kinds of food were detected by ELISA.The data were analyzed by using One-way analysis of variance.Results In this study,the rate of food intolerance was 0.4%(mushrooms) to 38.0%(eggs).Higher rates of food intolerance were found in egg,crab,shrimp,milk,and cod fish(Eggs 32.5%,crabs 26.0%,shrimps 19.8%,milk 13.8%,and cod fish 12.0% respectively).However,wheat,pork,and mushroom showed relatively lower rates of food intolerance(Wheat 0.8%,pork 0.4%,and mushrooms1.4% respectively).Positive reaction to food intolerance was even stronger in women(9.4% versus 8.2%).Conclusion It is discovered by study that in general population,the diversity of intolerance among different food is associated with 4 factors: gender; age; feature of food; individual diversity.It is recommended that the status of intolerance to food in the general population be investigated by health management.
