Objective: To evaluate the effects of stent implantation for treatment of Budd-Chiari syndrome. Methods:A total of 16 patients with pasthepatic inferior vena cave (IVC) obstruction syndrome were treated by balloon catheters ( Polythene and Inoue ) in percutaneous transluminal angioplasty (PTA) , then stent were inserted into the obstruction. Results: The residual pressure gradient after PTA and stent implantation was decreased from (4.6?0. 3 ) kPa to (2. 1?0. 1) kPa. The diameter of IVC after PTA and stent implantation was increased from (3.8?1. 7)mm to (14. 9?2. 0)mm. Conclusion : PTA and stent implantation are effective treatment for pasthepatic inferior vena cave obstruction.

Objective: To evaluate the effects of percutaneous balloon pulmonary valvuloplasty ( PBPV) for pulmonary valve stenosis (PS) by single-balloon, double-balloon and Inoue-balloon methods. Methods: PBPV was performed in 42 patients with PS. The systolic right ventricular pressure (SRVP) , systolic right ventricular outflow pressure and systolic pulmonary arterial pressure ( SPAP) were contrasted before and after the procedure. Systolic transpulmonary valve pressure gradient (TVPG) and total pressure gradient from right ventricular to pulmonary arterial after the procedure were compared among the three gropes. Results:SRVP, SRVOP were decreased from (14. 69?6. 01 )kPa, (12. 16?3. 48)kPa to (8.14?5.26)kPa, (5.39?2.21)kPa and PAP increased from (1.57?0.56)cm to (17. 16? 2.16)cm after PBPV, respectively. TVPGs were (2. 40?2. 05) kPa, (3. 29?2. 25 ) kPa, (2.52? 1.95)kPa and TPGs were (2. 40?2. 05)kPa, (4.98?4.26)kPa, (6.16?6.93)kPa, (5.65?4.75) kPa after PBPV by single balloon, double balloon and Inoue balloon methods, respectively. During the follow-up period (2. 5?1. 6) years, bloodflow velocity at pulmonary valve measured by supersonic Doppler decreased from (2. 38?1. 89) m/s immediately after PBPV to (2.22?1. 96) m/s, further TVPG decreasing was indicated. Conclusion: The short and long term results of PBPV for PS by each of the three methods were excellent. Inoue balloon may be the first choice for elder children and adults, while for younger children, single balloon method may be preferred. Double balloon method can be remained as the second choice when Inoue method failed.

OBJECTIVETo explore surgical treatment of gliomas involving the supplementary motor area (SMA) in the superior frontal gyrus.

METHODSClinical data and follow-up outcome of 16 patients with low graded astrocytomas involving the supplementary motor area were analyzed.

RESULTSSMA syndrome was developed in 6 patients in whom the posterior tumor resection line was at a distance of more than 1 cm from the precentral sulcus and resolved after 12 months. Hemiplegia occurred however in 8 patients in whom the resection line was less than 1 cm to precentral sulcus and only resolved in 3 patients during follow period 12 months.

CONCLUSIONSWhen the resection is performed at a distance of less than 1 cm from the precentral sulcus, surgery for gliomas of involving the supplementary motor area in the superior frontal gyrus may be result in permanent morbidity.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

In order to establish a method for the determination of the sterols of the oil in the freeze-dried acai (Euterpe oleracea Mart.) and to evaluate its antioxidant activities, a saponification/extraction procedure and high performance liquid chromatography (HPLC) analysis method were developed and validated for the analysis of phytosterols in PEE (Petroleum ether extract). Separation was achieved on a Purosper STAR LP C18 column with a binary, gradient solvent system of acetonitrile and isopropanol. Evaporative light scattering detection (ELSD) was used to quantify β-sitosterol and the total sterols. Peak identification was verified by retention times and spikes with external standards. Standard curves were constructed (r = 0.999 2) to allow for sample quantification. Recovery of the saponification and extraction was demonstrated via analysis of spiked samples. The highest content of total sterols is β-sitosterol. The antioxidant activities of the extracts were evaluated using the total oxyradical scavenging capacity assay (TOSC assay). The result showed that the PEE exhibited significant antioxidant properties, sample concentration and the antioxidant capacity had a certain relevance.
