Objective To investigate the feasibility and safety of three-dimensional video-assisted thyroidectomy (3D VAT). Methods During January to April of 2014, 10 cases with unilateral or bilateral thyroid benign diseases , thyroid cancer, or parathyroid lesions were enrolled .The 3D VAT was carried out by using a 10-mm 3D stereoscopic endoscope .Local excision or lobectomy was performed via a 2-4 cm curve skin incision one finger above the sternal notch .In two patients , lobotomy combined with systematic lymphadenectomy was performed when papillary thyroid microcarcinoma was identified during operation . Results All the procedures were accomplished successfully under 3D video-assisted system, without intra-operative abnormal blood loss or conversion to conventional thyroidectomy .The operative time was 30-90 min (61.8 ±22.4 min);the intra-operative blood loss was 1.3-93.0 g (median, 5.2 g).All the patients were followed up for 1-4 months.Neither intra-nor post-operative complications about recurrent laryngeal nerve , superior laryngeal nerve , or parathyroid were observed . Conclusions Preliminary impression emerging from this study seems to suggest that 3D VAT is safe and effective.Compared with 2D surgery, a good perception of depth and easy recognition of anatomic structures are noticeable .

Objective To evaluate the toxicological safety of Shanze weight-reducing food in order to provide some toxicological data for its application. Methods According to the national standard of safety evaluation, the following experiments of acute toxicity test through mouth in rats, the genetic toxicity test, thirty days feeding test and teratogenicity test in mice were performed. Results LD 50 was more than 20.0 g?kg -1, equivalent to 467 times of the recommended dosage, in acute toxicity test through mouth in both male and female rats, which fell into the scale of non-toxicity. Under the dosage range of 1.05 g?kg -1 to 4.20 g?kg -1, equivalent to 100 times of the recommended, the negative results were observed in the genetic toxicity test of micronucleus test of bone marrow cells, sperm shape abnormality test in mice and the Ames test. The negative impacts on the growth, development, hematology, biochemistry, histology and the ratio of organ to whole body were not found on the experimental rats of thirty days feeding. Under the same dosage range, no teratogenic effects were found in the experiments of teratogenicity test. Conclusions Shanze can be used as a kind of health weight-reducing food with toxicological safety under the experimental dosage range of 1.05 g?kg -1 to 4.20 g?kg -1.

Objective To make specific clear labels which can lead us to easily distinguish tube category,function,the drainage of fluid properties and so on,and to improve the safety of patients tube management.Methods Using BarTender software to create labels format,and printing out all kinds of the labels by bar code printer,pasting around at suitable locations.Results Labels designed and printed by Bar-Tender software could be more efficient,accurate and clear to mark patients’drain,which avoided illegible writing.Conclusion Labels de-signed and printed by BarTender software can help doctors and nurses identifying the tube and handover management.

Objective To compare the impact of bowel preparation on postoperative complications of patients undergoing radical cystectomy(RC) with ileal conduit diversion(ICD) by meta-analysis.Methods All literature were collected from VIP,CNKI,WanFang Data,CBMdisc,Pubmed,Medline,Embase dated from inception to April 2016.Then literature were grouped into mechanical bowel preparation and nonmechanical bowel preparation,whose differences in the wound,intestinal function,infection and other complications were compared.Results Three RCTs,four cohort studies and 656 cases were taken into account.No statistical difference was observed in the wound infection,wound dehiscence,fascia dehiscence,intestinal obstruction,anastomosis fistula,intestinal fistula,urinary leakage,death of indicators between the two groups.Conclusion Preoperative mechanical bowel preparation did not reduce the occurrence of postoperative complications of the patients with RC undergoing ICD.

Objective:To investigate the relationship between painful tonic spasm (PTS) and spinal cord injury in patients with neuromyelitis optica spectrum disorder (NMOSD).Methods:The clinical data, serum AQP4-IgG antibody levels and magnetic resonance data of 138 patients with NMOSD were analyzed. Those with spinal cord involvement were assessed using the American Spinal Injury Association Impairment Scale (AIS) to investigate the relationship between PTS and spinal cord injury.Results:The prevalence of PTS among the NMOSD patients was 36% (51/138), and all of the 51 NMOSD patients with PTS showed spinal cord lesions, an incidence significantly different from those without PTS. However, there were no significant differences in the age of onset, gender, disease duration, AQP4-IgG levels, lesion location, range of spinal cord lesions, or AIS grade between the NMOSD patients with and without PTS.Conclusion:PTS is a prevalent concomitant of NMOSD. As a common symptom of remission and recurrent remission, PTS is associated with myelopathy. This study failed to find any correlation between PTS and the affected spinal cord site or segment range. There was also no correlation between PTS and AIS grading among these subjects.

BACKGROUND: Synovectomy has been introduced into total knee arthroplasty (TKA) with the aim of relieving pain and inflammation of the synovium. However, there are no long-term, comparative data to evaluate the effect of synovectomy in TKA. This study was aimed at assessing pain, function, and complications in patients undergoing synovectomy during TKA for osteoarthritis (OA) at long-term follow-up. METHODS: This was a prospective randomized controlled trial of 42 consecutive patients who underwent staged bilateral TKA. Patients undergoing the first-side TKA were allocated to receive TKA with or without synovectomy followed by a 3-month washout period and crossover to the other strategy for the opposite-side TKA. The overall efficacy of both strategies was evaluated by determination of blood loss, the Knee Society score (KSS), and knee inflammation conditions during a 3-month postoperative period. The postoperative pain, range of motion (ROM), and complications were sequentially evaluated to compare the two groups until 10 years after surgery. RESULTS: At the 10-year follow-up, both groups had a similarly significantly improved ROM (114.88 ± 9.84° vs. 114.02 ± 9.43°, t  = 0.221, P  = 0.815) and pain relief with no differences between the two groups (1.0 [1.0] vs. 1.0 [1.5], U  = 789.500, P  = 0.613). Similar changes in total blood loss, KSS, and knee inflammation were found in both groups during 3 months postoperatively ( P  > 0.05). Additionally, there was no significant difference regarding complications and satisfaction between the two groups ( P  > 0.05). CONCLUSIONS: Synovectomy in conjunction with TKA for primary OA does not seem to provide any benefit regarding postoperative pain, ROM, and satisfaction during a 10-year follow-up. In addition, it may not result in more blood loss and increased incidence of long-term complications. Based on our long-term findings, it should not be performed routinely.
