Rat lung microvascular endothelial cells (LMVEC) were cocultured with rat pulmonary arterial smooth muscle cells (PASMC). The cultures were divided into 5 groups: normal group (N), lipopolysaccharide (LPS) 2h (L 2), LPS 8h (L 8), LPS 16h (L 16 ), and LPS 24h (L 24 ). The activity of IL 6 in LMVEC and PASMC supernatants was determined by radio immunity method, and the expression level of IL 6 mRNA in LMVEC was detected with RT PCR. The results showed that the activity of IL 6 in LMVEC and PASMC was enhanced by LPS at L 2, reaching the higher level after 8 hour stimulation. Furthermore, the activity of IL 6 was stronger in homotypic groups than that of coculture groups. The expression of IL 6 mRNA in LMVEC was increased in L2 group, and highest in L6 group, but lowered in L12 group, though it was still stronger than that of N. It suggest that IL 6 mRNA and the activity of IL 6 in LMVEC and PASMC were enhanced in both homotypic and coculture groups by LPS. And the mRNA level and activity of IL 6 were higher in homotypic groups than that of coculture groups.

Objective To analyze the safety and efficacy of early diet after laparoscopic resection of colorectal cancer.Methods A prospective study of 128 patients suffered laparoscopic surgery of colorectal cancer was done in our hospital.According to whether the adoption of early diet program,patients were divided into early oral group (EOF group,n=54)and traditional oral diet group (TOF group,n=74).Age,gender,preoperative nutritional status and other basic factors and postoperative ambulation time, postoperative hospital stay time,the number of cases the use of analgesics,complications of two groups were analyzed statistically. Results The first time of postoperative ambulation time and postoperative hospital stay time of EOF group were significantly re-duced compared TOF group [(1.2±0.8)d vs .(2.5±1.3)d]and [(3.2±1.4)d vs .(5.3±1.6)d](P <0.01).Conclusion Early diet after laparoscopic resection of colorectal cancer is good for patients fast recovery,and postoperative complications of two groups are similar.

Objective To compare the effect of mediastinal lymph node dissection by video -assisted thora-coscopic surgery (VATS)with thoracotomy in the treatment of lung cancer.Methods 96 patients with non -small cell lung cancer were collected.Patients undergoing VATS were matched with those undergoing thoracotomy in terms of gender,age,clinical tumor stage,tumor location and surgical procedure.Results After matching,48 patients in VATS group and 48 patients in open group were eligible for analysis.In the VATS and open groups,the mean total numbers of dissected lymph nodes were (27.2 ±7.4)and (28.8 ±10.6)(P =0.507),the numbers of N1 nodes were (9.4 ±4.0)and (8.3 ±4.6)(P =0.323).And the number of N2 nodes was similar between the VATS and open group [(18.5 ±6.9)vs (21.3 ±9.9),P =0.201].No significant differences were observed between the two groups(all P >0.05 ).But the days of the postoperation and the chest tube indwelling in thoracotomy group were (8.1 ±3.9)and (7.3 ±4.4)days,which in the VATS group were (6.8 ±3.5)and (5.6 ±3.5),the VATS group had more advantages than the thoracotomy group(P <0.05).The intraoperative blood loss more than 400mL and peri-operative blood transfusion rate of the thoracotomy group were 27.38% and 25.00%,those of the VATS group were 7.03% and 8.60% respectively,which in thoracotomy group were higher than the VATS group.Conclusion Under-go our retrospective study,after mature VATS to treat lung cancer,with regard to the number of the dissected lymph nodes,VATS lobectomy can achieve complete mediastinal lymph node dissection compared with the traditional approach.There are more advantages by VATS in the complications.

Background and purpose:Brucine is one of the active components from Strychnos nux vomica,with signifi cant analgesic,anti-inflammatory and platelet-aggregating inhibitory properties.Due to its cytotoxic effect,the anti-tumor effect of brucine has increasingly been appreciated.In this study,we investigated the impact of brucine on A549 cells proliferation,apoptosis as well as the underlying mechanisms.Methods:MTT assay was used to examine the cell viability,flow cytometric analysis and fluorescent microscope were applied to examine cell apoptosis,ELISA method was used to examine the effect of brucine on PGE2 release from A549 cells and RT-PCR analysis was used to measure mRNA content,western blotting analysis was used to measure protein expression and luciferase activity was detected to examine the effect of brucine on COX-2 promoter activity.Results:Brucine was able to suppress the proliferation of A549 cells and induce cell apoptosis to time-dependent and dose-dependent manner.To understand the mechanisms,COX-2 was identifi ed to be an important target molecule involved in the apoptosis induced by brucine because brucine could suppress the COX-2 mRNA,protein expressions as well as PGE2 release in A549 cells in a timedependent manner.Furthermore,overexpression of COX-2 abrogated brucine-induced cell apoptosis,in contrast,when A549 cells were transfected with COX-2 siRNA,the apoptotic effect of brucine was dramatically enhanced.Further analysis revealed that brucine was able to suppress COX-2 transcriptional activation.Conclusion:Brucine was able to induce lung cancer apoptosis via downregulation of COX-2.

Extended hemilaminectomy was performed in the treatment of compression of the cervical spinal cord produced by ossification of the posterior longitudinal ligament, multilevel degeneration and protrusion of the intervertebral discs and simple spinal canal stenosis. The results showed that with this operation the cross sectional area of the spinal canal was enlarged by 50% of the original, and the sagittal diameter lengthened 2,5mm postoperatively, so the compression of the. spinal cord was relieved. Since the function of the spinal process, the supra-and interspinal ligaments and the structure of one side of the lamina were preserved, mechanical stability of the cervical spine was maintained.

OBJECTIVE To investigate the relation of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) expression with cervical lymph metastases in papillary thyroid carcinoma. METHODS The expression of COX-2 and VEGF in 79 specimens of papillary thyroid carcinoma were evaluated with SP immunohistochemical methods. In all the 79 cases, there were 46 cases with cervical lymph node metastases and 33 cases without cervical lymph node metastasis. RESULTS The positive expression rates of COX-2 and VEGF in the cases with cervical metastases were 81.6 % and 86.8 % respectively, and in the cases without cervical lymph metastases were 54.5 % and 66.7 % respectively. There was a significant difference in the positive expression rates of COX-2 and VEGF between two groups (P

Objective To investigate the positive detective rate of interlobar node in the operation of non-small cell lung cancer (NSCLC), and to compare the effect of interlobar node dissection by video-assisted thoracoscopic surgery (VATS) with thoracotomy in treatment of lung cancer. Methods 108 patients with NSCLC who received the surgery by the same group of thoracic surgeons were collected from Aug 2012 to Mar 2016 in Guangdong Medical University Affiliated Kaiping Central Hospital. The positive transfer and detective rates of interlobar node in patients with different clinical and pathological stage were analyzed. Then the patients were divided into traditional open thoracotomy group and VATS group according to the operation mode, meanwhile, the number of interlobar nodes dissection in the two groups were compared. Results The positive transfer rates of the interlober nodes in patients with different clinical stage were ⅠA 5.7 % (2/35),ⅠB 5.0 % (1/20), ⅡA 14.3 % (3/21), ⅡB 13.3 % (2/15), ⅢA 29.4 % (5/17); For patients with different pathological T stage were T1A 8.3 % (2/24), T1B 9.1 % (2/22), T2A 12.9 % (4/31), T2B 14.3 % (2/14), T3 21.4 %(3/14), T4 33.3 % (1/3), and over-all transfer rate was 13.0 % (14/108). In pathology stage and pathology T stage, the number of interlober nodes had no statistical difference in traditional open thoracotomy group and VATS group (all P>0.05). Conclusions Even in the early clinical stage, the transfer of interlobar node may be positive. The transfer rate of interlobar node is correlated positively with pathology T stage. VATS can achieve the same effect in interlobar node dissection compared with the traditional approach.
