1. A rat model of multiple organ dysfunction syndrome induced by subarachnoid hemorrhage
Chinese Journal of Cerebrovascular Diseases 2006;3(3):123-126
Objective: To establish a rat model of multiple organ dysfunction syndrome (MODS) by subarachnoid hemorrhage (SAH), and to explore the pathogenesis of MODS occured in acute cerebrovascular diseases (ACVD). Methods: Model of SAH was induced in rats by injecting arterial blood around the Willis' circle. 48 Wister rats were randomly divided into three groups: normal control group (n = 6), sham-operative group (n = 6) and SAH group (n = 36). The SAH group was further divided into 6 groups according to the time points of 4h, 12h, 24h, 36h, 48h and 72h after SAH, each group has six rats. Changes of temperature, heart rate and respiratory rate of the rats in each group were recorded, the amount of white blood cell (WBC) and biochemical criteria were assayed. Pathological changes of lung, liver, intestines and kidney were observed under optical microscope. Systemic inflammatory response syndrome (SIRS) and MODS were diagnosed by their criteria. Results: 1 There were no significant differences of temperature, heart rate, respiratory rate and the levels of WBC, ALT, AST, BUN, Cr and CK between normal control group and sham-operative group (P > 0.05). The rats of SAH group had obviously higher temperature, heart rate, respiratory rate, WBC, ALT, AST, BUN, Cr and CK than that of the normal control group and sham-operative group (P < 0.01), the changes were most obvious at 24-36 hour point. 2 The vital organs of the rats showed inflammatory injuries in varying degree at each time point after SAH, and peaked on 24-36 h, alleviated after 48 h, and last to 72 h after SAH. 3 The incidences of SIRS, MODS and mortality were 100% (36/36), 69.4% (25/36) and 38.9% (14/36) respectively in the SAH group. Conclusion: 1 An experimental animal model of MODS can be established successfully by injecting arterial blood around the Willis' circle in rats. 2 SAH can cause inflammatory changes in lung, liver, intestines, kidney as well as SIRS, and SIRS may be the pathological basal of MODS after SAH.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disease in males, which is characterized by persistent discomfort or pain in the pelvic region. As currently used drug therapies fail to produce satisfactory results, it is an urgent task to find new and effective methods for the treatment of CP/CPPS. In recent years, many reports are seen on the extracorporeal shock wave therapy (ESWT) for CP/CPPS. ESWT can significantly improve the symptoms of pelvic pain and urination disorders in CPPS patients, and its therapeutic effect is attributed to the improvement of angiogenesis and block of pain nerves.

Objective The aim of this paper is to know about the pollution of microcystin-LR(MC-LR)in Fenhe First reservoir and Fenhe Second reservoir in Taiyuan and provide reference for making the policy of prevention microcystin-LR pollution.Methods During the low water period(May,2005)and common period(Oct,2005),5 liter water was sampled in the entrance,the center and the exit in Fenhe First reservoir and Fenhe Second reservoir respectively.The concentrations of MC-LR in two reservoirs were determined by the high-performance liquid chromatography(HPLC).Results The average concentration (0.875 ?g/L)of MC-LR in low water period was 3 time of that(0.283 ?g/L)in common period in Fenhe First reservoir.The average concentration(0.815 ?g/L)of MC-LR in low water period was 17 time of that(0.048 ?g/L)in common period in Fenhe Second reservoir.The level of MC-LR in the entrance was the highest,that in the exit was the lowest,that in the center was middle. The concentration of MC-LR of the entrance in low water period was more than the MC-LR limit(1 ?g/L)in Life drinking water hygienic guide(2001).Conclusion MC-LR pollution has been found in Fenhe First reservoir and Fenhe Second reservoir and the pollution is serious in low water period.

Objective:To evaluate the safety and efficacy of a palliative regimen of computed tomography (CT)-guided 125I seed im-plantation combined with chemotherapy for recurrent ovarian cancer. Methods:A total of 21 patients with recurrent ovarian cancer, who received 125I seed implantation and chemotherapy, were retrospectively analyzed. Out of the 29 lesions detected, 25 lesions were suitable for 125I seed implantation. Treatment planning system (TPS) was implemented preoperatively to determine the number and dis-tribution of 125I seeds. Under CT guidance, 125I seeds were implanted into the recurrent lesions using the TPS. Within 3 d of 125I seed im-plantation, liposomal paclitaxel was administered by intravenous infusion on day 1 and carboplatin by infusion via the feeding artery of tumor on day 2. Chemotherapy was repeated on a 21-day schedule. Efficacy and complications were evaluated during follow-up. Re-sults:After two cycles of chemotherapy, out of the 25 recurrent lesions that underwent 125I seed implantation, four lesions showed com-plete remission, 14 with partial remission, three with stable disease, and four with progression of disease. The objective response rate was 72%, and the pain relief rate was 82.4%. Karnofsky's performance status scores increased dramatically (P=0.019). The median pro-gression-free survival time was 6.8 months, median overall survival time was 14.2 months, and the 1-year survival rate was 42.9%. He-matologic toxicity and gastrointestinal reactions were the primary adverse conditions. No severe radiation complications and treat-ment-related deaths were observed in all patients. Conclusion:CT-guided 125I seed implantation combined with chemotherapy is active and well-tolerated in patients with recurrent ovarian cancer. This combined treatment cannot only significantly enhance the objective re-sponse rate, but also leads to remarkable improvement in cancer-related symptoms.

Objective To explore the influence of homocysteine(Hcy)on liver cystathionine-?-synthase(CBS)and methylenetetrahydrofolate reductase(MTHFR)system in apoE-/- mice,and determine the effects of atorvastatin and/or folate/vitamin B12 on liver CBS and MTHFR system.Methods Eighty male 6-week-old apoE-/- mice were randomly divided into two groups:65 mice were fed with a chow diet containing 2%(wt/vol)L-methionine(homomethionine group)and 15 mice were fed with normal saline(control group).Two months later,the 60 mice survived in homomethionine group were subdivided into four groups:group Ⅰ(untreated),Ⅱ(3 mg/kg atorvastatin),Ⅲ(3 mg/kg atorvastatin+2 mg/kg folate+30 ?g/kg vitamin B12)and Ⅳ(2 mg/kg folate+30 ?g/kg vitamin B12).After one month,Western blotting was performed to detect the liver CBS and MTHFR system protein expression in each group.Results The relative expression of liver CBS and MTHFR was significantly lower in group Ⅰ than in control group(P

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.
