  • Efficacy and Safety of Chinese Medicinal Herbs for Endometriosis: A Systematic Review

    Objective To assess the efficacy and safety of Chinese medicinal herbs for treating endometriosis. Methods We searched Cochrane Library, MEDLINE, EMBASE, CBM (from establishment to 2003). Randomized controlled trials (RCTs) and quasi-randomized controlled trials of patients with endometriosis were included. The quality of included studies such as randomization, blinding, allocation concealment and loss of follow up were evaluated and meta-analysis was performed by RevMan 4.3 software. Results Ten RCTs or quasi-RCTs involving 1 120 patients were included. Because of different therapies in the treatment and control groups, the results of outcome were described separately. Most of included studies suggested that the effects of traditional Chinese medicine (TCM) on general effect, pregnancy rate improvement and alleviating dysmenorrhoea were similar to Danazol or Tamoxifen, only a few studies showed better effects. There was no evidence to support that TCM was more effective than western medicine in reducing the size of endometriotic cysts. Only one study mentioned the recurrence rate and showed that TCM enema had lower recurrence rate than oral Tamoxifen with OR 0.17, 95%CI 0.04 to 0.67. Five studies mentioned adverse reactions and showed TCM had fewer adverse effects than western medicine. Conclusions Chinese medicinal herbs are effective in treating endometriosis with fewer adverse effects. The evidence is not b enough because of low quality of the included studies. Therefore, more high quality randomized controlled trials are required.

  • ECTOPIC OSTEOGENESIS OF IMMORTALIZED HUMAN BONE MARROW MESENCHYMAL STEM CELLS AND HETEROGENEOUS BONE

    Objective To provide the seed cells for bone tissue engineering, to establ ish immortal ized human bone marrow mesenchymal stem cells (MSCxj) and to investigate the ectopic osteogenesis of MSCxj. Methods MSCxjs of the 35thand 128th generations were maintained and harvested when the cell density reached 2 109. Then, these cells were co-cultured with heterogeneous bone scaffold in groups A (the 35th generation, n=12) and group B (the 128th generation, n=12); heterogeneous bone alone was used in group C (n=12). The cell prol iferation was observed by scanning electron microscopy (SEM) after 48 hours and 18 days of osteogenic induction culture. The complex was implanted subcutaneouly through a 3-mm-incision at both sides of the back in 18 nude mice. Tetracycl ine label ing was performed before the animals were sacrificed. Tetracycl ine fluorescence staining, HE staining, ponceau staining, and immunohistochemistry staining for osteocalcin were performed at 4, 8, and 12 weeks after transplantation; the morphologic quantitative analysis was made. Results After 48 hours, SEM showed that MSCxjs adhered to heterogeneous bone and grew well; after 18 days, a large number of new filamentous extracellular matrix and small granules were found to cover the cells. The results of tetracycl ine fluorescence staining, HE staining, and ponceau staining in groups A and B showed that the osteogenesis was not obvious at 4 weeks after transplantation; osteoid matrix deposition was noted around and in theheterogeneous bone at 8 weeks; and osteogenesis was increased at 12 weeks. There was no significant difference in bone formation between groups A and B. Osteogenesis was not observed in group C. The osteocalcin expressions were positive in groups A and B. The bone ingrow percentages of groups A and B were 5.64% ± 2.68% and 4.92% ± 2.95% at 8 weeks, and 13.94% ± 2.21% and 14.34% ± 3.46% at 12 weeks, showing significant differences between 8 weeks and 12 weeks at the same group (P lt; 0.05) and no significant difference between groups A and B at the same time (P gt; 0.05). Conclusion MSCxj has favorable abil ities of ectopic osteogenesis and can be appl ied as seeded cells in bone tissue engineering.

  • Surgical treatment strategy and outcome of functional univentricular heart with total anomalous pulmonary vein drainage

    Objective To explore the surgical management method and outcome of functional univentricular heart with total anomalous pulmonary vein drainage (UVH-TAPVD). Methods We reviewed the surgical procedures and results for 44 UVH-TAPVD patients in our hospital between the year 2010 and 2016. There were 34 males and 10 females. The age of the patients was 312 (77-4 220) d when they accepted the first surgical treatment. Results There were 8 deaths in stage Ⅰ palliation, 1 death in stage Ⅱ palliation and 5 deaths during the follow-up. The overall survival rate was 68.2% (30/44). Glenn operation was undertaken in 34 patients with 5 deaths. Fontan operation was undertaken in 9 patients with 2 deaths. Conclusion Surgical strategies for UVH-TAPVD should be planned according to different anatomical and pathophysiological conditions in different patients. Staged palliations can reduce mortality and morbidity. But pulmonary venous obstruction and heterotaxy syndrome are still risk factors for these patients.

  • The operative strategy after palliative shunt for corrected transposition of great artery (cTGA) with left ventricular outflow tract obstruction and cardiac malpostion

    ObjectiveTo explore the operative strategy after palliative shunt for correcting congenitally corrected transposition of great artery (cTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malpostion.MethodsWe retrospectively analyzed the clinical data of 54 patients with onsecutive cTGA with LVOTO and cardiac malpositon from June 2011 to May 2019. The patients were devided into two groups. There were 24 patients (16 males and 8 females at mean age of 5.4±2.2 years) who underwent one and a half ventricle repair as a one and half ventricle group. And there were 30 patients (19 males and 11 females at age of 8.6±6.2 years) who underwent one ventricle repair operation as a one ventricle group. Follow-up data were collected by telephone interviews.ResultsThere was no statistical difference in systemic atrioventricular valve regurgitation and systemic ventricular ejection fraction between the two groups (P>0.05). Compared with one and a half ventricle group, the cardiopulmonary bypass time (CPB) time, mechanical ventilation time and intensive care unit stay were significant shorter than those in the one ventricle group (P<0.05), but prolonged pleural effusions developed more frequently in the one ventricle repair group (P<0.05). There was no in-hospital death but 1 follow-up death in each group. The follow-up time was 49 (17-38) months in the one and half ventricle group at follow-up rate of 93.9%, and 47 (12-85) months at follow-up rate at 90.9% in the one ventricle group. One and a half ventricle group had better systemic ventricular ejection fraction (EF) than that in the one ventricle repair group. And the rate of heart function (NYHA) class Ⅲ and class Ⅳ in one and a half ventricle group was lower than that in the ventricle group. No significant difference of survival and freedom from re-intervention probability between the two groups was found.ConclusionFor patients of correction of cTGA with LVOTO and cardiac malposition after palliative shunt, the one-and-a-half ventricular repair procedure is ideal operative strategy.
