Objective To analyze the perioperative conditions and long-term survival of patients with non-small cell lung cancer (NSCLC) after thoracoscopic lobectomy. Methods 119 patients with NSCLC underwent thoracoscopic lobectomy from January 2006 to December 2012 were enrolled in the study, then collecting and analyzing their perioperative indicators, pathological results and follow-up data. Results 9 patients converted to thoracotomy with a conversion rate of 7.0 %. The median operation time, the median intraoperative blood loss and off-bed activity time were 170 min (65~440 min), 90 ml (15~3 000 ml) and (32.9 ± 16.3) h after operation respectively. The time and amount of postoperative drainage, the length of hospital stay were (6.7 ± 3.2) d, (1 690.0 ± 410.5) ml, (9.2 ± 4.0) d respectively. The incidence of perioperative mortality and postoperative complications were 0.8 %, 13.4 % respectively. For postoperative pathological type, 96 cases of adenocarcinoma, 19 cases of squamous carcinoma, 2 cases of adenosquamous carcinoma and 2 cases of large cell carcinoma. For discharge patients, the median follow-up time was 34.5 months (0 ~ 102 months). The incidence of local recurrence and distant metastasis in observation group were 5.0 % and 17.6 % respectively. 1-year overall survival (OS) and disease free survival (DFS) were 85.3 % and 79.5 %, 3-year OS and DFS were 69.8 % and 64.8 %, 5-year OS and DFS were 60.8 %and 58.6 % respectively. There was no significant difference in 1-year, 3-year and 5-year OS and DFS between adenocarcinoma and squamous carcinoma (P > 0.05) while there were significant difference in local recurrence and distant metastasis among different stages (P < 0.05). In addition to slightly low OS, DFS of Ⅲ a , Ⅲ b and Ⅳ DFS and OS, the overall living conditions among all stage were similar. Conclusions The long-term survival condition of thoracoscopic lobectomy for NSCLC is ideal, and it’s a safe and effective operation, worthy of clinical promoting.

Objective To develop the personalized 3D printing scaffolds for bone grafts,to meet the needs of the patients with the bone defect.Methods The model of three-dimensional woodpile structure was designed by the software of computer-aided design (CAD).The β-tricalcium phosphate (β-TCP),hydroxyapatite (HA),and polylactic acid (PLA) composite scaffolds with three-dimensional woodpile structure was simulated using 3D printing method by three-dimensional air floating platform.The three-dimensional bone graft scaffolds was then vacuum heat-treated,and the residual chloroform was detected by energy dispersive X-ray spectrometer.The morphology of the β-TCP/HMPLA scaffolds was characterized by scanning electron microscope,and in vitro cytotoxicity against osteoblasts hFOB 1.19 was assessed by thiazolyl blue tetrazolium bromide (MTT) assay.Results When the extrusion pressure of printing slurry was 137.9-413.7 kPa,the three-dimensional bone graft scaffolds could be printed out.Then the scaffolds was vacuum treated at 90 ℃ and preheated at 150 ℃,which could eliminate the solvent CHC13.The three-dimensional bone graft scaffolds,with a through-hole and rough surface,was co-cultured with osteoblasts hFOB1.19 for 7 d,and it's cytotoxicity grade was grade 0.Conclusions The three-dimensional bone graft scaffolds have a through-hole and rough surface,which is favorable to the osteoblasts culture and bone induction,indicating the advantage and development prospects of 3D printing in the preparation of porous materials for bone grafts.

Objective To systematically evaluate the safety and efficacy of probiotics in the treatment of severe acute pancreatitis (SAP).Methods The randomized controlled trials (RCTs) for studying probiotics in the treatment of SAP were retrieved from databases,including PubMed,Embase,Cochrane Library,Medline,Chinese Biomedical Literature Database (CBM),Chinese science and technology journal full-text database (VIP),China journal full-text database (CNKI),Wanfang academic journal fulltext database.The methodological quality of included literatures was evaluated,and statistical analysis was performed via RevMan5.3 software.Results A total of 12 pieces of RCT literatures including 910 cases of patients with SAP were included.The results of meta analysis indicated that no statistically significant difference was found in the mortality [RR =0.97,95 ％ CI(0.63,1.49),P=0.88],the incidence rate of multiple organ dysfunction [RR =0.72,95 ％ CI(0.49,1.06),P=0.10] and the incidence rate of pancreas-related infections [RR=0.76,95 ％ CI(0.54,1.07),P=0.12] between the probiotics group and the control group;while there were statistically significant differences in the length of hospital stay [MD =-3.74,95 ％ CI(-6.37,-1.12),P=0.005] and the incidence rate of intestinal ischemia necrosis [RR=11.39,95 ％ CI(1.5,86.4),P =0.02],Conclusion Probiotics could not improve clinical outcomes of patients with SAP,and may increase risk for intestinal ischemic necrosis.However,it could shorten the length of hospital stay.

Objective To detect the expression of survivin in suprarenal epithelioma(SRE) and elucidate its function in suprarenal epithelioma.Methods A total of 53 SRE specimens and 8 nomal nephridial tissues were obtained.Immunohistochemistry method was used to test protein expression of survivin.Semi-quantitative RT-PCR was used to measure survivin mRNA levels.Results Survivin protein were detected in 33 of 53(62.3%) SRE tissues.In contrast,no expression of survivin in nomal nephridial tissues was detected.The expression rate of survivin mRNA in tumor tissues(56.25%,18/32) was significantly higher than that in normal tissues(0,0/8).Conclusion Over expression of survivin is common in suprarenal epithelioma.Survivin may play an important role in SRE and is associated with prognosis.

Experiment Ⅰ. Twenty-eight rats were randomly assigned into Near-Infrared Information Radiation (NIIR) group and control group. Two weeks later each rat was innoculated intraperitoneally with Salmonella typhosa H antigen (HAg) and cyclophosphamide (CY). Peripheral lymphocyte counts in the NIIR group were significantly higher than those in the control group on the fifth day after administration of CY. Experiment Ⅱ, Fifty-four rats were randomly divided into NIIR group given CY and H Ag intraperitoneally, CY and H Ag group and H Ag group for treatment. By the end of the fourth week, the survival rate and serum IgG level in the NIIR group were significantly higher than those in the CY and HAg group. By the end of 2nd week, the titer of the anti-H antibody of the HAg group and NIIR group was significantly higher than that of the CY and HAg group. Experiment Ⅲ. Thirty rats were randomly allocated to NIIR group and control group. Spleen cells were taken and cultured with Con A for 24h to induce IL-2 and the activity of IL-2 in the NIIR group was significantly higher than that in the control group. The NK activity in NIIR group was higher but not significant and ADCC in the NIIR group was significantly higher than that in the control group. The results suggest that NIIR is capable of enhancing immunoreaction in immunosuppressive bodies by promoting the function recovery of T helper cells, therefore NIIR is effective to regulate the immunological function on chronic active hepatitis.

Primary hyperparathyroidism (PHPT) is a disorder of calcium metabolism, which is characterized by elevated blood calcium and PTH urine calcium, which is easy to involve multiple systems. The disease is mainly caused by a benign adenoma of parathyroid tissue, a few of which are parathyroid hyperplasia or parathyroid adenocarcinoma. As awareness of physical examination increased, the proportion of asymptomatic PHPT patients gradually increased. The disease can be cured by surgical resection of the parathyroid gland, most of which is a real good prognosis, but a few of them are complex and difficult to diagnose and treat. At present, there continue to be many controversies about the diagnosis and treatment of PHPT.This article is a review of the progress in the diagnosis and treatment of PHPT.
