Objective To study the influence of different time of lavipeditum with traditional Chinese medicine on recovery of gastrointestinal function right after cesarean section, to find the best lavipeditum time and improve the therapeutic effect of lavipeditum with traditional Chinese medicine. Methods 388 cases parturents after cesarean section were selected and were randomly divided into the observation group(200 cases)and the control group(188 cases)according to their bed number. The observation group began lavipeditum with Chinese medicine 6 hours after operation, and was scheduled 7:00-8:00 in the morning, 21:00-22:00 in the evening, lasted 20 minutes every time for consecutive 3 to 5 days. the control group started lavipeditum with Chinese medicine one day after operation, and continued lavipeditum any time they wanted. lasted 20 minutes every time for consecutive 3 to 5 days. Recovery of intestinal function were com-pared between the two groups. Results Postoperative recovery time of bowel sounds, anal exhaust time for the first time, the first defecation time, appetite and sleep quality three days after operation in the observation group were beuer compared with the control group. Conclusions Timing of lavipeditum with Chinese medicine is more effective for recovery of gastrointestinal function after cesarean section, it embodies the importance of time medicine and reach best aims.

Objective To explore the diagnostic value of high frequency three-dimensional (3D) ultrasound in breast masses.Methods Seventy-seven cases of breast lesions were selected by 2D ultrasonic scan,and all the cases had been examined by 3D ultrasound and accepted surgical treatment in Shenzhen People's Hospital.With pathological results as the gold standard for diagnosis,the convergence sign in diagnosis of breast masses was used as malignant standard for 3D ultrasound coronal plane.The sensitivity and specificity were analyzed of 3D ultrasound in the diagnosis of benign and malignant breast tumors.Results A total of 77 cases of breast lesions included 46 malignant and 31 benign.3D ultrasound convergence sign was used to judge the benign and malignant breast tumors with statistical significance (x2 =26.790,P ＜ 0.01).The diagnostic sensitivity and specificity were 69.7％,and 90.3％,respectively.Conclusions High frequency 3D ultrasonography has certain value in differential diagnosis of benign and malignant breast tumors,and has important significance for the formulation of treatment plan.
