Baicalin protects thymus of rats with severe acute pancreatitis.

To study the protective role of Baicalin on rats thymus with severe acute pancreatitis (SAP). The SAP rats were randomly assigned to the model control, Baicalin treated and Octreotide treated groups. Normal rats were assigned to the sham-operated group. The rat survival rates, pathological changes of thymus, apoptotic indexes and expression levels of NF-kappaB, Bax, Bcl-2, Caspase-3 and P-selectin of all groups were observed and recorded at 3, 6 and 12 h after operation, respectively. Rat survival rates were significantly higher in both Baicalin- and Octreotide-treated groups than those in the model control group at 12 h (P < 0.05). The thymus pathological score was significantly lower in Baicalin treated group than in control group at 3 and 12 h (P < 0.05). The expression of NF-kappaB, Bax and Bcl-2 in thymus tissue was negative in all groups. At 3 h after operation, the staining intensity, positive staining rate and intensity of Caspase-3 protein in the thymuses of the Baicalin treated group were significantly higher than those in the model control group (P < 0.01). At different time points after operation, no marked difference was observed in the staining intensity of P-selectin protein between the Baicalin treated group and the model control group (P > 0.05). At 6 h after operation, the positive staining rate and intensity of P-selectin protein in the Baicalin treated group was significantly lower than those in the model control group (P < 0.05). The apoptotic indexes were significantly higher in treated group than in model control group at 6 h (P < 0.05). Baicalin has a protective role on the thymus of SAP rats, and its effect of decreasing inflammatory mediators level in blood, inhibiting P-selectin expression and inducing apoptosis of thymocytes may involve in the mechanism of its protective role.

Objective To evaluate the TriVex system in the treatment of varicose veins of lower extremities,focusing on postoperative complications and management.Methods Clinical data of 108 patients (146 legs) of varicose veins of the lower extremity undergoing TriVex procedure were retrospectively analyzed.Deep veinons patency was verified in all patients by preoperative sonography.Above knee stripping of the great saphenous vein was done first when necessary.The below knee phlebectomy of the side branches was done with the new system (Trivex System/Smith and Nephew).Postoperative patients were followed-up,and results were evaluated.Results Procedure was successful in all cases.98 cases were followed up for 1 ～ 24 months.The mean operation time per leg was (34±8) minutes.Complications were as following:26 legs (17.8%) developed postoperative hematoma which was healed by conservative therapy including two cases in which the tension seroma,which was successfully managed by puncture aspiration.Transien skin numbness or paraesthesia developed in 13.0% (19/146).Subcutaneous induration in 11.6%(17/146) cases.Residual varicose and recurrence in 3.4% (5/146).Incision related complications developed in 4.8% (7/149) cases.Conclusion Transilluminated powered phlebectomy (TriVex) is a safe and effective cosmetic procedure for less invasive varicose vein surgery.

Influence of baicalin on TNF-alpha mRNA, caspase-3 and P-selectin expression in pancreatic tissue of rats with severe acute pancreatitis.

OBJECTIVE: Baicalin reduces the severity of severe acute pancreatitis (SAP) in a rat model. This study was carried out to examine the effect of baicalin on TNF-alpha mRNA, caspase-3 and P-selectin protein expression in the pancreas of rats with SAP. METHODS: Rats with SAP were randomly assigned to untreated, baicalin-treated, octreotide-treated and sham-operated group. The TNF-alpha mRNA expression level, caspase-3 and P-selectin protein expression levels of pancreatic tissue were measured 3, 6 and 12 hours after operation. RESULTS: The caspase-3 protein expression level was significantly higher in the treated groups than that in the untreated group at 3 hours (p <0.01). P-selectin protein expression level in pancreas of the treated groups was significantly lower than that of the untreated group (p <0.05 or <0.01). TNF-alpha mRNA expression level in pancreas decreased in baicalintreated group while untreated group increased at different time points (p <0.05). CONCLUSION: Baicalin increases caspase-3 expression and inhibits TNF-alpha mRNA and P-selectin protein expression in pancreatic tissue of SAP rats.
