Objective To determine the effect of interlocking intramedullary nail in treatment of open tibial and fibula fractures and analyze the method to promote the bone union. Methods From December 2003 to June 2006, thirtyfive patients with open tibial and fibula fracture were treated with emergency debridement, interlocked intramedullary fixation for tibia and fixed fibula at the same time. During operation, the bone marrow was collected and grafted into the fracture gaps. Among them, there were 27 males and 8 females, involving in 22 left legs and 13 right legs. Their ages ranged from 19 to 65 years, with an average of 34.7 years. The location of fracture was the middle of the tibia and fibula in 16 cases, the distal 1/3 of the tibia and fibula in 12 cases and the proximal 1/3 in 7 cases. According to the Gusitilo classification of open injuries, there were 7 cases of type I, 19 cases of type II, 8 cases of type III a and 1 case of type III b. The mean range of knee motion was 48.3° (45-70°). The mean time from injury to operation was 4.3 hours (50 minutes to 7 hours). Results The mean operation time was 94 minutes (60-132 minutes) and the mean blood loss was 122 mL (100-350 mL). The wound healed by first intention in 32 patients. Incision was sutured in 2 cases of type III a fractures after operation 4 days, gastrocnemius flap graft was performed in 1 case of type III b fracture 1 week after operation. They all achieve good heal ing. No fractures spl it off, no iatrogenic nerve and vascular injury occurred, no osteofascial compartment syndromes or deep vein thrombus happened. Tension bl isters appeared in 1 case of type II fracture after operation and subsided after 5 days. Patients were followed up for 14-43 months (mean 22 months). The X-ray films showed that fracture union was observe in 30 cases after 14 weeks of operation, in 3 cases after 18 weeks and in 1 caseafter 22 weeks of operation. The fractures union time was 15.2 weeks on average. About 2 cm nonunion in lateral tibial appeared in 1 case of type I fracture. No fracture occurred again. The mean range of knee motion was 127° (121-135°). The mean HSS score was 96.5 (87-100) at the end of the follow-up. The excellent and good rate was 100%. Conclusion The curative effect of interlocking intramedullary nail is definite in treatment of open tibial and fibula fractures and it can enhance fracture union to plant bone marrow into the fracture gaps.
Objective To evaluate the effectiveness of terazosin, tamsulosin and finasteride for benign prostatic hyperplasia (BPH). Methods We searched the related original studies all over the world, and only included randomized controlled trials (RCT) and quasi-randomized controlled trials (CCT). MEDLINE (1966 to Dec. 2004), EMBASE (1984 to Dec. 2004), The Cochrane Library (Issue 4, 2004) and four Chinese databases were electronically searched and 10 related journals were handsearched. The studies included in the references of eligible studies were additionally searched. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted the data from the eligible studies, with confirmation by cross-checking. Divergences of opinion were consulted by a third party. Meta-analysis was performed by using RevMan 4.2 software. Results Twelve original studies involving 2 471 participants met inclusion criteria. Compared with terazosin, tamsulosin could improve international prostatic symptom score, with WMD 0.75, 95% confidence interval (CI) 0.03 to 1.46, P=0.04. There was no statistical difference between terazosin and tamsulosin in improving the average rate of urine flow (WMD 0.23, 95%CI -0.39 to 0.85, P=0.46), the residual urine volume (WMD 0.82, 95%CI -2.92 to 4.57, P=0.67) and in diminishing the volume of prostate (WMD 2.20, 95%CI -3.99 to 8.39, P=0.49). There was no statistical difference between finasteride and tamsulosin in improving the international prostatic symptom score (WMD 0.65, 95%CI -0.45 to 1.75, P=0.25) or the max rate of urine flow (WMD 0.39, 95%CI -0.72 to 1.51, P=0.49). Only two studies compared finasteride with terazosin and had different conclusions. Only one study compared finasteride or terazosin with a combination of these drugs suggested that the combination had higher effective power than finasteride alone but no difference with terazosin alone. Conclusions Although the effectiveness in some aspects is higher in the tamsulosin group, there is not enough evidence to show which one is the best among these three drugs. The combination of finasteride and terazosin does not show more effectiveness than terazosin alone. This review suggests that tamsulosin alone should be used for the treatment of BPH and the combination needs to be identified by better evidence. It is important to improve the quality of original studies.
Objective To evaluate the clinical efficacy of fistula repair by stapler technique in patients with cervical tracheoesophageal fistula. Methods Retrospective analysis of 8 patients with cervical tracheoesophageal fistula who accepted operative treatment in the Department of Thoracic Surgery, Lanzhou University Second Hospital from October 2014 to October 2016 was conducted. There were 5 males and 3 females at a mean age of 46.4±13.9 years ranging from 23 to 67 years. The fistula was induced by tracheal intubation in 4 patients, by esophageal foreign bodies in 2, by tracheal stent in 1 and by esophageal diverticulum in 1. The fistula was closed by stapler technique. The surgical effects were evaluated through Karnofsky performance score (KPS), image assessment, patient satisfaction score and assessment of improvement in feeding-induced bucking. Results The operations were performed successfully with time of 117.5±6.6 min and intraoperative blood loss of 60.0±7.0 ml. After the operations, the patients did not suffer incision bleeding and infection, hoarseness, dyspnea, drinking-induced bucking, fistula relapse, tracheoesophageal stenosis or any other complications, and no death occurred during the perioperative period. The chest X-ray test was performed 1 week later showed that the pulmonary infection disappeared, and only 1 patient suffered from esophageal stenosis 1 year later. The postoperative KPS score was 90.0±7.0 points, which significantly improved in contrast to preoperation (P<0.01). Postoperative pulmonary infection area reduced significantly (P<0.05), tracheoesophageal fistula disappeared, postoperative patients satisfaction rate was 90%, and assessment of feeding-induced bucking was excellent. Conclusion Using stapler technique to repair cervical tracheoesophageal fistula is safe, easy and useful, with less operation time and postoperative complications.

Objective To evaluate the effect of music therapy for childbirth. Methods Such databases as The Cochrane Library, PubMed, EMbase, EBSCO host, SpringerLINK Online Journals, CBM and WanFang Data were searched from January of 2000 to December of 2010 to collect randomized controlled trials (RCTs) of music therapy for childbirth. The quality of RCTs was appraised and the data were extracted. Meta-analyses were conducted with RevMan5.02 software for the standarded RCTs. Results A total of nine RCTs were included. Five RCTs indicated the music therapy could alleviate the labor pain; five RCTs indicated the music therapy could reduce the event risk of cesarean section due to the failure of transvaginal trial labor; three RCTs indicated the music therapy could shorten the first stage of labor; two RCTs indicated the music therapy could stabilize the systolic pressure and heart rate when complete cervical dilation was done, and three RCTs indicated the music therapy could relieve anxiety. In addition, music therapy had no influence on neonate Apgar’s score; and the result of meta-analyses on postpartum hemorrhage was not reliable through sensitivity analyses. Conclusion The music therapy applied during childbirth can relieve the labor pain and anxiety, stabilize the heart rate and systolic pressure when complete cervical dilation is done, reduce the event risk of cesarean section due to the failure of transvaginal trial labor, shorten the first stage of labor, and is beneficial to the mind and body of parturient.
Objective To evaluate the safety and mid- to long-term efficacy of surgical correction of isolated partial anomalous pulmonary venous connection (IPAPVC). Methods We retrospectively collected consecutive patients who were diagnosed with IPAPVC and underwent surgical correction at Fuwai Hospital of Chinese Academy of Medical Sciences and Fuwai Yunnan Cardiovascular Hospital from June 2009 to May 2019, summarized the basic preoperative and intraoperative data of patients, analyzed the postoperative and mid- to long-term follow-up results. Results A total of 54 patients were enrolled, including 29 males and 25 females, with an average age of 16.20±2.40 years, ranging from 1 month to 62 years. There were 28 (51.9%) patients with varying degrees of arrhythmia, 22 (40.7%) patients with cardiac insufficiency, and 39 (72.2%) patients with pulmonary hypertension. According to Bordy's typing, 14 (25.9%) patients were classified as type A, 23 (42.6%) type B, 4 (7.4%) type C, 5 (9.3%) type D and 8 (14.8%) mixed type. Transthoracic echocardiography was performed in the whole group of patients and the accuracy of staging diagnosis was 66.7% (36/54), and cardiac CT angiography (CTA) was performed in 37 patients and the accuracy of staging diagnosis was 94.6% (35/37). All surgical procedures were assisted with cardiopulmonary bypass, aortic cross-clamping time was 0-219 (67.02±5.23) min, cardiopulmonary bypass time was 40-261 (105.09±5.23) min, and there was no serious intraoperative complication. Postoperative tracheal intubation time was 0-230 (13.33±4.20) h, intensive care unit stay was 0-13 (1.89±0.28) days, postoperative hospital stay was 5-18 (7.20±0.38) days, and follow-up time was 16-140 (62.58±5.12) months. There were 2 (3.7%) all-cause postoperative deaths, including 1 in-hospital death and 1 death during the follow-up, and there was no intraoperative death. Among the survivors, there were 3 patients with surgery-related complications: 1 patient had atrial septal defect with the second surgical treatment, 1 early obstruction of the superior vena cava and 1 arrhythmia. Two patients had complications of IPAPVC (atrial fibrillation, collateral circulation) prior to surgery and underwent the second surgery with a poor prognosis, and 1 patient had preoperative cardiac insufficiency and atrial fibrillation, whose symptoms persisted for a long time during the follow-up. Conclusion IPAPVC accounts for a lower percentage of partial anomalous pulmonary venous connection, transthoracic echocardiography combined with CTA improves diagnostic accuracy, and IPAPVC should be treated with elective surgery after diagnosis. The surgical approach should be individualized with imaging features such as disease staging, number of drains and drainage location. Surgical treatment of IPAPVC is safe and effective, and regular follow-up is warranted.
