Objective To evaluate the efficacy of decortication by video-assisted thoracic surgery (VATS) in pa﹣tients with tuberculous empyema, and discuss its indications. Methods 60 patients with tuberculous empyema who underwent decortication by VATS for surgical management from December 2010 to December 2015 were included. Under a thoracoscope, we cleaned up the pus, separated adhesions, scraped granulation tissues and caseous necrosis on the inner wall of the abscess cavity, and stripped the thickened fiberboard of the parietal and visceral pleurae. Af﹣ter the procedure, sufficient drainage and antituberculosis therapy were carried out. Results All the patients in this group were operated successfully. All the patients were cured without perioperative death and complications. No re﹣currence of empyema was observed at the follow-up examination from 2 months to 5 years, and suffered pulmonary reexpansions were better. Conclusions The decortication by VATS for tuberculous empyema is safe, effective, mini﹣mally invasive. The imaging manifestations of pleural thickening in 1 cm, no obvious calcification, no serious lesions in the lungs are the indications for the operation.

Objective To study the protein components of the secretion of the proximal trunk of transected peripheral nerve and the effect of the secretion on the growth of motor neuron.Methods After the sciatic nerves of rats were transected, the proximal trunk secretion collecting compartment (P-SCC), distal trunk SCC (D-SCC) and (proximal) plus distal trunk SCC (PD-SCC) were set up. The protein components of the solution in the 3 types SCC were analyzed by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrum. And the effect of 3 kinds solution on the growth of motor neuron was tested by the motor neuron culture respectively. (Results) All the P-SCC, D-SCC and PD-SCC were filled with light yellow, clear fluids. The protein (concentration) was (5.45?1.2)mg/ml,(3.87?0.7)mg/ml and (5.68?1.5)mg/ml in the solution of PD-SCC, P-SCC and D-SCC (respectively). The protein patterns of the 3 solution were similar, and the detected (protein) spots were 1098?34,985?47 and 1021?36 spots in the solution of P+D-SCC, P-SCC and D-SCC (respectively). Most of the protein spots (distributed) in the rangs of MV 25-90KD and PH 4-8. The results of motor neuron culture demonstrate that the number of survival cells, cell area, neurite length and OD value of experimental groups(including mix group, (proximal) group and distal group) are generally higher than control group. But there is no obvious difference between the three experimental groups. Conclusions (1)The proximal trunk of transected sciatic nerve had the similar secretive ability as the distal nerve trunk.(2)(Protein) image of the 3 kinds of SCC solution showed that proteins from the three SCC solution were homologous. (3)All the 3 kinds of SCC solution could promote the growth and activity of motor neuron, and there was no difference in function between P-SCC and D-SCC solution.

Objective To research whether the inhibitory oligonucleotides could improve the immune status of the BXSB mice. The purpose was to provide a valuable direction for treating systemic lupus erythematosus. Methods 3-month-old BXSB lupus mice were divided into three groups (including inhibitory oligonucleotides group, saline group and blank control group). The 24 hours urine proteins were determined before treatment. After treatment,the urine protein, anti-dsDNA, peripheral blood lymphocytes apoptosis and immune complex in renal glomeruli were measured. Results Before treatment,the urine proteins had no statistical differences among the three groups ( P > 0.05 ).After treatment,the urine protein, anti-dsDNA levels in inhibitory oligonucleotides group were significantly lower than that of control group(P < 0.01 ). Apoptosis of peripheral blood lymphocytes in inhibitory oligonucleotides group was significantly higher than that of control group( P < 0.05 ) ,immune complex in renal glomeruli in inhibitory oligonucleotides group was significantly lower than that of the other groups ( P < 0.05 ). Compared with saline group, inhibitory oligonucleotides had prolonged life period of BXSB mice ( P < 0.01 ). Conclusion The inhibitory oligonucleotides could improve immune status of BXSB, and could put off the disease progression.
