Objective: To study the prevention and treatment mechanism of Qingxia therapy (based on Yinchenhao Decoction and Dachengqi Decoction) on hepatocyte apoptosis in rats with acute hepatic injury induced by lipopolysaccharide plus D-galactosamine (LPS/D-GalN)., Methods: The acute hepatic injury model was established by LPS/D-GalN and then intervened with Qingxia therapy. Serum liver function, PT and liver tissue pathology were observed, hepatocyte apoptosis index was detected by Tunel, protein expressions of BCL-2, BAX and Caspase-3 were detected by Western blotting., Results: Qingxia therapy could significantly decrease serum ALT, AST and TBIL levels (P < 0.01 or 0.05), reduce hepatocyte necrosis and inflammatory cell infiltration. There were more apoptotic cells in model group, which had significant differences compared with Qingxia group and control group. Protein expressions of BAX and Caspase-3 in model group were significantly higher than those in control group and Qingxia group (P < 0.05), but BCL-2 protein expression in model group was lower (P < 0.05)., Conclusion: Qingxia therapy can ameliorate the liver function and hepatic tissue pathology of rats with hepatic injury induced by LPS/D-GalN, alleviate hepatocyte apoptosis in rats, prevent and treat hepatocyte apoptosis by down-regulating the protein expressions of Caspase-3 and BAX, up-regulating the protein expression of BCL-2, and adjusting the balance of BCL-2/BAX.

Objective: To explore the techniques and outcomes of the surgical treatment for varicose vein., Methods: Totally 2 200 patients with varicose vein received surgical treatment in our hospital from July 2000 to January 2006. The latest techniques for endovenous occlusion were used for most cases, among which 1 802 cases were treated with endovenous laser treatment (EVLT) combined with transilluminated powered phlebectomy (TIPP), 82 cases with radiofrequency endovenous occlusion (RFO) combined with TIPP, and 218 cases with limited invaginated vein stripping and foam sclerotherapy. The remaining 98 cases were treated with laser, radiofrequency or ligation for saphenous vein trunk, and with resection, electric coagulation, and transfixation for vein clusters as additional methods. Perforators were also cut and ligated as well., Results: Satisfied surgical results were obtained in all cases. The average operative time was 40 minutes (range 20-78 minutes)., Conclusions: Limited invaginated vein stripping, EVLT, and RFO can be used to treat saphenous vein reflux. Surgical resection, transfixation, electric coagulation, and sclerotherapy are reasonable options for vein cluster or tributaries. Transection and ligation of the perforators are important. TIPP is ideal for the treatment of vein clusters.

Objective: To explore the effective and safety of carotid endarterectomy (CEA) in the treatment of severe stenosis of internal carotid artery., Methods: The clinical data of 95 patients with internal carotid artery stenosis and treated by CEA in our hospital from October 1998 to October 2006 were retrospectively analyzed. Transient ischemic attack (TIA) was found in 65 patients and cerebral infarction in 21 patients before operations. Diagnoses were confirmed by selective angiography, and > 70% stenosis of internal carotid artery was found in all patients and > 95% stenosis was found in 50 patients. Stenosis or occlusion of the contralateral carotid artery was also found in 35 patients. Coronary artery stenosis was confirmed in 43 patients with preoperative coronary angiography. CEA and coronary artery bypass grafting (CABG) were simultaneously performed in 18 patients., Results: After the operation, the clinical symptoms significantly improved in all patients. One case experienced hypoglossal nerve injury. One patient died of heart attack during follow-up., Conclusion: CEA is an effective and safe treatment for severe stenosis of internal carotid artery.

Objective: To observe the clinical curative effect of chronic hepatitis B treated by the four-step therapeutics of Traditional Chinese Medicine (TCM)., Methods: 120 patients with mild or moderate Chronic Hepatitis B (CHB) were randomly divided into two groups: 80 patients in treatment group and 40 in control group. All enrolled cases accorded with the enroll standard. In treatment group, the patients were divided into mild moderate and severe degree of immune intervention based on the ALT level and treated with four-step therapeutics according to the dialectical theory. In control group, all patients were administered 100mg Lamivudine orally daily for two years., Results: The loss rates of HBeAg, HBV-DNA, precore mutation were 58.9%, 78.9% in treatment group respectively, and 33.3%, 38.9% in control group. There were significant defferences between them. The total effectiveness ratio of two groups has no significant difference. After the treatment, the value of HA, PCIII, IV. C,LN decreased dramatically in treatment group and the antihepatic fibrosis results of treatment group were superior to those of control group. The four-step therapeutics of TCM could improve the ALT value and the ALT value declined to normal after the virus indexes' loss. The response rate in treatment group of ALT-elevating patients was higher than those of no ALT- elevating patients., Conclusion: The four-step therapeutics of TCM is effective in treating the CHB patients.

Objective: To investigate the therapeutic effect of percutaneous lumbar discectomy (PLD) combined with sodium hyaluronate (SH) injection in the treatment of lumbar intervertebral disc herniation., Methods: Forty-eight patients suffered from lumbar disc herniation were divided into two groups and treated by PLD combined with SH injection into epidural cavity (treatment group) or single PLD (control group) respectively. All patients were followed up for 24 months. The therapeutic effects in both groups were assessed and compared according to Macnab's criterion., Results: The patients in the treatment group got much more significant improvement than those in the control group, with shorter therapeutic course and more safety., Conclusion: PLD combined with SH injection into epidural cavity is more effective and safety in the treatment of lumbar disc herniation than of pure PLD.
