Objective To calibrate and assess the dose distribution of 125 I seed brachytherapy. Methods Twenty 125 I seeds, each with activity of 12.2 MBq, were implanted on the circumference of a circle 15mm across in a phantom. Into a designed prostate model, 70 125 I seeds were implanted in four planes. The absorbed dose rate of the target volume was monitored by Farmar 2570 dosimeter and thermoluminescence dosimeters (TLD) with the isodose curves drawn on Kodak films. Results The central dose rates of the circular target volume assessed by Farmar 2570 and TLD were 8.4, 7.9 cGy/h in the phantom and 12.0, 11.1 cGy/h in the prostate model. For the target volume of the prostate model, the total absorbed dose was 24?219 cGy. The dose rate 4 cm from the prostate cancer as shown by the isodose curves was only 10% of the central dose rate. Conclusion The central dose rate of target volume measured by the two methods are similar.

Objective To evaluate the effectiveness of suberselective uterine arterial embolization for uterine fibroids.Methods Uterine arterial embolization with golyvimylalcohol(PVA) particles or Iodized oil and Gelfoam or Pingyangmycin lipiodol and Gelfoam was performed in 182 patients with uterine fibroids.Results Bilateral and unilateral superselective uterine arterial embolization were performed in 173 cases and 9 cases respectively. 6～28 months (mean 11 months) after the procedure, complete disappearance of tumor(16 cases), an average shinkage of 67% in tumor volume(152 cases) and a mean 42% reduction of uterine volume were obtained in 168 followed-up cases. The clinical symptoms were relieved significantly.The main side effets were hypogastic pain(135/182).Conclusion Superselection uterine arterial embolization is an effective and microinvasive method in treating uterine fibroids.

Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P

Objective To evaluate the cLinical outcome and influencing factors of open reduction and internal fixation in treatment of hip dislocation combined with acetabular fractures. Methods A retrospective analysis was performed on 51 patients with hip dislocation combined with twetabular frac-tures, who were treated with open reduction and internal fixation under general anesthesia in the emergen-cy department on admission. Of all, 41 patients were treated with open reduction and plate/screw internal fixation, for which the reduction result was evaluated by postoperative X-rays and follow up X-rays accord-ing to Matta's criteria and the functional outcome by Merle d' Aubigne's criteria. Results Of 41 pa-tients, 33 were followed up for 1-7 years (mean 3.1 years). X-ray evaluation showed anatomic reduction in 27 patients (82%), imperfect reduction in five (15%) and poor reduction in one (3%). The clini-cal outcome at the time of final follow-up was graded as excellent in 18 patients (55%), good in 8 (24%), mederate in 3 (9%) and peor in4 (12%), with total excellence rate of 79%. Conclusion Prompt reduction of hip dislocation, precise reduction of the acetabular fracture and decrease of periopera-tive comphcations are key to excellent clinical outcome.

A new steroid with a long cross-conjugation structure, 15a-hydroxy-(22E, 24R)-ergosta-3, 5, 8 (14), 22-tetraen-7-one (1), was isolated from the marine-derived fungus Aspergillus aculeatus. Its structure was established by the extensive spectroscopic analyses, and its cytotoxicities against P388, HL-60, and PC-3 cell lines were measured in vitro.

Objective To study whether the human bone marrow mesenchymal stem cells (HBMSCs) can repair damaged neural cells induced by okadaic acid (OA).Methods Neuroblastoma cell line SH-SY5Y cells were used to incubate with 20nmol/L okadaic acid for 24h,establishing Alzheimer's Disease cell model;Three groups were set up:normal group,okadaic acid-damaged (OA-damaged) group,hBMSCs-treatment group.The cells were injured for 24h with 20nmol/L OA in OA-damaged group,and treated with conditioned medium obtaining hBMSCs for 24h after 24h OA injury in the treatment group.Then CCK-8 was used for detecting cell vitality,immune fluorescence dyed microtubules and micro filaments for determining the dendritic cell length and fluorescence intensity,in addition,Western blotting for analyzing the protein level of phosphorylated tau and total tau proteins.Results Okadaic acid damaged SH-SY5Y cells,contributed to shrinkage,collapse,cavitation of the SH-SY5Y cell body,dendritic shortening and fracture,and irregular arrangement of microtubule microfilaments;while BMSCs conditioned medium made SHSYSY cell body become round and longer,dendrites restored,and microtubules and microfilaments arranged regularly,fluorescence intensity enhanced.Meanwhile,it also down-regulated the level of OA-induced tau phosphorylation.Conclusion hBMSCs have repair effects on the neural cell damage induced by okadaic acid.
