Objective To summarize the clinical experience of video-assisted thoracoscopic surgery (VATS) for thoracic diseases. Methods Clinical data of 207 patients receiving VATS form October 1997 to March 2004 were retrospectively analyzed. Among them, there were 155 cases of spontaneous pneumothorax treated by pulmonary bubble ligation or resection, 30 cases of spontaneous or traumatic hemopneumothorax treated by urgent exploration, 14 cases of pulmonary benign diseases undergoing pulmonary wedge resection and biopsy, and 8 cases of mediastinal tumor resection. Results Surgical procedures were completed thoracoscopically in 190 patients and were accomplished under thoracoscope with an additional mini-thoracotomy in 12 patients, while conversions to open surgery were required in 5 patients. The time of surgical procedures was 20~180 min (mean, 56 min). The postoperative hospital stay was 5~52 d (mean, 9 d). Postoperative complications occurred in 17 cases (8.2%, 17/207), including 9 cases of persistent air leakage, 6 cases of re-expansion pulmonary edema, and 2 cases of infection of thoracic cavity. Spontaneous pneumothorax reoccurred in 2 patients 3~4 months postoperatively. Conclusions VATS offers more advantages over traditional thoracotomy for the treatment of spontaneous pneumothorax pulmonary bubble, traumatic hemopneumothorax and selected chest benign diseases. The combination with mini-thoracotomy under certain circumstance may contribute to assuring the safety of this procedure.

8kPa, 113 cases of type ASD and VSD with diameter from 0.5 to 2.0 cm were operated upon with open heart technic from June 1995 to June 1999. There was no mortality, no air embolism, except in 4 cases operation was only completed under moderate hyperthermia and cardiac arrest instead due to poor vision of the operating field. 12 cases were complicated by slight hemoglubinuria after 24h of operation, and 1 case by remnant VSD. 95 cases were followed up, and they were in healthy condition. This operative technic is suitable for the repair of secondary ASD, and small or moderate, membranous or para membranous VSD. Its advantage is less myocardial damage, and shorten the duration of cardiac arrest. Air embolism is likely to take place by using this method, but effective method should be taken to prevent it.

Leptin is a protein hormone produced mainly by obese gene and secreted by adipose tissue and exerts the biological effects through leptin receptors. With the progress in research on the function and receptor signal transduction related leptin and leptin resistance, it has been found that leptin is associated with the development and progression of many cardiovascular diseases, such as hypertension and left ventricular hypertrophy. Some studies have reported that leptin resistance is the pathologic basis for a variety of cardiovascular diseases. This paper will briefly review the advances in the study of correlation between leptin and hypertensive-left ventricular hypertrophy (HLVH), focusing on the relationship between leptin and various factors related to HLVH, such as sympathetic nervous system, renin angiotensin aldosterone system, growth factors, inflammatory factors and insulin resistance.

OBJECTIVE: To observe the improvement effects of water extract of Glycyrrhiza uralensis on acute hepatic injury caused by triptolide and its effects on the levels of IL-10 and TNF-α in rats. METHODS: A total of 60 healthy male SD rats were randomized into blank control group, model group, positive control group (magnesium isoglycyrrhizinate) and G. uralensis water extract low-dose, middle-dose and high-dose groups. Blank control group and model group were given isochoric normal saline intragastrically; positive control group was given Magnesium isoglycyrrhizinate liquid intragastrically (13.5 mg/kg); G. uralensis water extract low-dose, middle-dose and high-dose groups were given G. uralensis water extract intragastrically 1 mL (120, 240, 480 mg/kg, by the amount of extract), qd, for consecutive 7 d. At 8th day of administration, model group, positive control group and G. uralensis water extract groups were given Triptolide liquid intragastrically (0.6 mg/kg) to establish acute liver injury model. HE staining was used to detect the pathological changes of liver tissue in rats. The activities of ALT and AST in serum were determined by enzyme coupling reaction. The protein expression of IL-10 and TNF-α in liver tissue were analyzed by Western blotting. RESULTS: Compared with blank control group, obvious pathological changes of liver tissue in rats were observed in model group; serum activities of ALT and AST, the protein expression level of TNF-α in liver tissue were increased significantly, while the protein expression level of IL-10 was decreased significantly (P<0.01). Compared with model group, pathological changes of liver tissue were relieved significantly. Except for the activity of AST in serum of rats in G. uralensis water extract low-dose group, the activities of ALT and AST in serum, the protein expression level of TNF-α in liver tissue were decreased significantly in G. uralensis groups, while the protein expression level of IL-10 in liver tissue was increased significantly (P<0.05 or P<0.01). CONCLUSIONS: G. uralensis water extract can relieve triptolide-induced acute liver injury in rats, the mechanism of which may be associated with expression down-regulation of pro-inflammatory factor TNF-α and expression up-regulation of anti-inflammatory factor IL-10.

Interleukin-33 (IL-33) is a new member of the IL-1 cytokine family which plays roles in the nucleus as a nuclear factor and is released by damaged or necrotic cells to act as a cytokine. It can be released via damaged or necrotic cells and functions as a cytokine. The released IL-33 activates the downstream NF-κB and MAPKs signaling pathways through the isomers of the specific receptor ST2 and the interleukin-1 receptor accessory protein (IL-1RAcP), resulting in danger signals and the activated multiple immune responses. IL-33 is abnormally expressed in various tumors and involves in tumorigenesis, development, and metastasis. Moreover, IL-33 can play both pro-tumor and anti-tumor roles in the same type of tumor.
