Objective To explore the value of laparoscopic ovarian-conserving restoration for ovarian cyst torsion . Methods A total of 62 cases of ovarian cyst torsion , 12 of which were combined with pregnancy , between January 2007 and June 2012 were retrospectively analysed .The surgical management involved laparoscopic high ligation of ovary blood vessels , restoration of the ovary, and resection of ovarian cysts . Results All the 62 cases of laparoscopic restoration were successfully performed with ovarian reservation.The cysts twisted for 180°~1080°, including 19 cases of <360°, 21 cases of 360°~720°, and 22 cases of >720°.The cysts were coloured purple black in 26 cases, purple or normal in 36 cases.The operation time was (57 ±23) min, the intraoperative blood loss was 5-130 ml (mean, 50.6 ml), and anal exsufflation time was (24 ±13) hours.No embolism, infection, and abortion occurred during post-operation.The level of estrogen recovered to normal in 1-3 months postoperatively .Ovulation at the procedure side was found in 43 cases in 6-24 months. Conclusions Laparoscopic ovarian-conserving surgery is a safe procedure for ovarian cyst pedicle torsion .High ligation of ovarian blood vessles and resection of ovarian cysts can not only avoid the possibility of thrombosis but also preserve the ovarian functions .The shortage of this operation is complicated to perform .

Objective:To observe the effect on the apoptosis of breast cancer cell MCF-7 with acupunctural and moxibustional therapy.Methods:Zusanli and Sanyinjiao neiguan in both sides of female Wistar mice were acupunctured and moxibusted.MCF-7 cell was cultirated with the serum.To detecte the cytoxicity with MTT,and detecte the apoptosic rate and Fas expression rate with flow cytometry after 72 hours.Results:The Fas expression was obviously increased upto 57.70% after 72h.The proliferation of MCF-7 was inhibited remarkably.The inhibition rate were 17.55%,24.71% and 31.85% after 12h,24h and 72h.The apoptosic rate were 8.72% and 10.18% after 72h,remarkably higher than the control group(P

This study was aimed to assist the clinic diagnosis and analysis with the application of modern ausculta-tion diagnosis technology. Meanwhile, this study provided certain objective evidences for traditional Chinese medicine (TCM) auscultation diagnosis in syndrome differentiation according to Zang-Fu. The Voice Sampling System of TCM was used in the collection of voice signals of patients with liver-depression and spleen-deficiency, deficiency of both heart and spleen, disharmony between heart and kidney (231 cases). Meanwhile, voice signals of healthy peo-ple (100 cases) were used as the control group. Based on wavelet packet decomposition and reconstruction technique, four kinds of featured parameters, including energy proportion, generalized energy proportion, energy gradient and generalized energy gradient, were extracted. The results showed that there were significant differences in multiple fre-quencies on energy proportion, generalized energy proportion, energy gradient and generalized energy gradient be-tween the liver-depression and spleen-deficiency, deficiency of both heart and spleen, disharmony between heart and kidney, and healthy people (P< 0.05). There were significant differences in multiple frequencies of four features a-mong samples from each type (P < 0.05). The generalized energy proportion of the deficiency of both heart and spleen type was higher than patients from other types and healthy people. The generalized energy gradient of healthy people was lower than the other three types. Differences were mainly posterior to the middle frequency segment. The recognition rate of three types and healthy people was ideal after feature screening. It was concluded that modern auscultation diagnosis technology can be used in the analysis of TCM phonetic feature parameters among common TCM syndrome types. The research results provided references for the objective study of TCM auscultation diagnosis. It provided theoretical evidences for the objective detection of TCM auscultation diagnosis and intelligent computer.
