BACKGROUND: The morbility of rheumatoid arthritis is closely associated with cell apoptosis process. Hyperplasia of synoviocyte lies in the relatively insufficiency of synoviocyte apoptosis. Therefore, induction of synoviocyte apoptosis has clinical significance in the treatment of rheumatoid arthritis. Arteannuin and its derivatives can induce the apoptosis of various cells. OBJECTIVE: To observe the effect of artesunate on the expression of Fas/FasL and Bcl-2/Bax, which are correlated with apoptosis in synoviocyte of adjuvant arthritis. DESIGN: Randomized and controlled observation. SETTING: First College of Clinical Medical Science, Three Gorges UniversityMATERIALS: The experiment was conducted in the laboratories of Immunology and Morphology, Three Gorges University from September 2005 to November 2005. Fifty 8-week-old male Wistar rats of clean grade and (150±21) g were provided by the Animal Experimental Center of Tongji Medical College, Huazhong University of Science and Technology; Complete Freud adjuvant by SIGMA, U.S., and artesunate solution by Guilin Pharmaceutical Corporation.rabbit anti-mouse Fas (SC-716), rabbit anti-mouse FasL and Technology (No. SCXK 2004-2007).Complete Freud adjuvant (SIGMA, U.S. No. 093K8932); artesunate solution (Guilin Pharmaceutical Cor); rabbit anti-mouse Fas (SC-716), rabbit anti-mouse FasL multi-antibody (SC-834), goat anti-mouse IgG-HRP multimer, rabbit anti-mouse P53 (M3566) multi-antibody, Bcl-2 (sc-7382) multi-antibody, rabbit anti-mouse Bax (sc-7480) multi-antibody, ABC compound reagent kit and DAB coloring reagent all acquired from Santa Cruz biotechnology (Santa Cruz, USA); methotrexate (MTX) purchased from Shanghai Hualian Pharmaceutical Co., Ltd.; microscope and image analysis system obtained from Leica (Leica,Germany); microtome (Leica, Germany).METHODS: Fifty rats were randomly divided into six groups: normal group (n =8), model group (n =8), high dose artesunate group (n =8), low dose artesunate group (n =8), artesunate plus methotrexate (MTX) group (n =8), and MTX group (n =8). ①Model construction was referred to literature: Except the normal group with 0.1 mL normal saline, all rats were injected with 0.1 mL complete Freund's adjuvant into the right voix pedis to establish the models of adjuvant arthritis. Since the 13th day after modeling, high and low dose artesunate groups were intraperitoneally injected with 40 and 20 mg/kg artesunate, respectively everyday; artesunate plus MTX group was intraperitoneally injected with 20 mg/kg artesunate everyday and 0.4 mg/kg MTX every three days; MTX group with 0.4 mg/kg MTX solution every three days;model group with 1 mL normal group everyday. ②The arthrosis index (Al) of each group was evaluated before and 13 days after administration; the expressions of Fas/FasL, Bcl-2, and Bax in synovial membrane tissue were examined by immunohistochemistry.MAIN OUTCOME MEASURES : Al and the expression of Fas/FasL, Bcl-2, and Bax in synovial membrane tissue of each group.RESULTS: Fifty rats were involved in the result analysis. ①Thirteen days after administration, the Al of each experiment group (including model control) was remarkably lower than that before treating (P ＜ 0.01). The Al of eachexperiment group was significantly lower than that in model control group (P ＜ 0.01). ②The expression of Fas/FasL in high and low dose artesunate groups and artesunate plus MTX group was up-regulated significantly compared with that in model group (P ＜ 0.01). There was no statistically significant difference in the expression between MTX group and model group (P ＞ 0.05); the expression of Bcl-2 was significantly down-regulated but Bax up-regulated in two artesunate groups,artesunate plus MTX group and MTX group compared with that in model group (P ＜ 0.05).CONCLUSION: The findings suggest that artesunate could alleviate adjuvant arthritis, up-regulate the expression of Fas/FasL and Bax, but down-regulate that of Bcl-2, in which the induction of synoviocyte apoptosis may be one of the mechanisms.

OBJECTIVE:To observe the clinical efficacy and ADR of Mirabilite combined with intrapetitoneal in the treatment of elderly colorectal malignant ascites. METHODS:77 cases of patients with elderly colorectal malignant ascites were randomly di-vided into treatment group (n=40) and control group (n=37). The control group received the treatment of intraperitoneal alone, while the treatment group was based on the control group additionally received Mirabilite combined with intrapetitoneal. The clini-cal efficacy,quality of life (QOL),and ADR in 2 groups were compared and statistically analyzed. RESULTS:Compared with control group,the effective rate in treatment group was 77.5% and the disease control rate was 87.5%,with significant difference (P<0.05);the QOL score in treatment group was better than control group,with significant difference(P<0.05);the incidence of local ADR in Mirabilite for external use was low. CONCLUSIONS:Mirabilite combined with intraperitoneal has better efficacy in the elderly colorectal malignant ascites and better QOL.

OBJECTIVE: To summarize advances in clinical application of ureter stent and its biocompatibility. METHODS: A computer-based online search of CNKI (1989/2009) and Medline (1989/2009) was performed with the key words of "ureter, biocompatibility, stent, treatment, complications" in Chinese and English respectively. A total of 51 articles were collected. and 21 were included. The treatment advances and its biocompatibility of ureter stent were summarized, and clinical application advances, biocompatibility and complication prevention of ureter stent were explored. RESULTS: Ureter stent includes polymerizer, metal and degradable material stents. As the common implants in treatment of upper urinary tract diseases, ureter stent functions as stent and internal drainage, and relieve ureteral obstruction, prevent leakage of urine postoperatively and ureterostenosis. Complications following ureter stent implantation include stent shifting, urine reflux, irdtative symptoms of bladder, fouling and stone formation as well as infection. However, these complications can be relieved through positive treatment. CONCLUSION: Ureter stent is an effective approach to treat urologic disease, but the biocompatibility required improvement. Rigorous operation during stent implantation and positive treatment of complication can effectively prevent complications.

Objective: To analyze the related factors of postoperative complications after laparoscopic assisted D2 radical resection for advanced gastric cancer. Methods: From August 2015 to July 2017, 80 patients with advanced gastric cancer admitted to the First Hospital of Jiaxing were selected.All the patients were treated with laparoscopic-assisted D2 radical resection, and the risk factors related to postoperative complications were analyzed by logistic regression analysis model. Results: There were 33 cases (41.25%) with postoperative system complications, 19 cases (23.75%) with complications of level Ⅱ and above; 15 cases (18.75%) with postoperative local complications, among them 12 cases (15.00%) appeared level Ⅱ and above local complications.The number of concomitant diseases and age were related risk factors for systemic complications in patients with advanced gastric cancer after laparoscopic D2 radical resection (OR=1.982, 95%CI: 2.183-34.405, OR=6.587, 95%CI: 1.738-23.495, all P<0.05). The preoperative neoadjuvant chemotherapy, reconstruction method and age were the risk factors for local complications in patients with advanced gastric cancer after laparoscopic D2 radical resection (OR=8.273, 95%CI: 4.982-35.394, OR=12.304, 95%CI: 2.384-88.921, OR=6.365, 95%CI: 2.183-21.384, all P<0.05). Conclusion Treatment of advanced gastric cancer patients with laparoscopic D2 radical mastectomy, attention should be paid to control the patients' age, preoperative neoadjuvant chemotherapy, reconstruction mode, associated disease and other related risk factors.In order to ensure the safety of patients and to avoid postoperative complications.
