Objective To study the role of cell apoptosis during the chemotherapy of human gliocytoma in order to get effective suvilliance on the effect of chemotherapy. Methods Gliocytoma cells were isolated and cultured from 40 human gliocytoma samples. Mitochondrial membrance potential (MMP), cell cycle, the level of Bcl-2 and Bax were detected by flow cytometry (FCM) at 24, 48, 72 hours respectively of incubation with Lomustine (CCNU) and Teniposide (VM-26), and the trends were also analysed. Results MMP decreased greatly, the apoptosis part in the cell cycle ananlysis increase, the expression level of Bcl-2 decreased, and that of Bax increase rapidly, while the Bcl-2/Bax ratio decreased. Conclusions CCNU and VM-26 have singnificant effect in gliocytoma chemotherapy on inducing gliocytoma cell apoptosis. VM-26 has more stronger effect on the cell cycle. MMP is the most sensitive and the fastest index in apoptosis detection.

Objective To study the differences of clinical and histopathologic features between ischemic colitis (IC) and ulcerative colitis (UC), which can make for the differential diagnosis and treatments. Methods Comparative analysis were focused on the clinical and histopathologic data of IC patients (20 cases) and UC patients (30 eases). Results The onset duration of IC [(5±7) d] was significantly shorter than that of UC [(953±1354) d]. IC patients tended to have history of cadiovascular diseases or abdominal surgery (65%). The typical clinical manifestations of IC were sudden onset of abdominal pain (85%), hematochezia (60%)and diarrhea (50%), but UC usually presented with abdominal pain (83%), diarrhea (63%), bloody mucopurulent stool (57%) and tenesmus (20%). Colonoscopy showed longitudinal ulceration (60%)on the mesenteric side, the segmental lesions usually involved only 1/4-1/2 of the perimeter of the lumen (80%), and the boundary of lesions was clear (75%) in IC patients. On the contrary, the ulcer of UC was usually map-like (43%), the lesions usually involved the entire lumen (90%), and the pseudopolyp (37%) was another colonoscopic feature of UC. The histopathologic study revealed that dilation and hyperaemia of vessels (90%) were common in IC. Severe edema of mucosa (95%) was usually presented in IC, and the thickened vascular wall (50%) was the histopathologic characteristic of IC.Crypt abscesses (47%) usually appeared in UC. Conclusions The histopathologic characteristics and differences of colonoscopic findings and clinical features provide strong bases for the differentialdiagnosis between IC and UC.

Objective To study the association between endometrioid uterine carcinomas and metabolic syndrome (MS). Methods A retrospective study was conducted on 123 patients who were admitted in Department of Gynecology Oncology, Zhejiang Cancer Hospital (study group) and 90 healthy women (control group) with matching age from Jan. 2005 to Mar. 2009. The general conditions[including age, whether menopausal, body mass index (BMI)];the risk factors for MS [including waist circumference,fasting plasma glucose, triglycerides(TG), high-density lipoprotein (HDL) and systolic and diastolic blood pressure]were analyzed. The clinical stage, histological type, and pathology differentiated degree of study group with or without MS were also analyzed by univariate analysis and Cox proportional hazards models.Results (1) The univariate survival analysis shown that there were no significant difference with age in two groups[(54.3±0.6) vs. (54.2±0.9) years;P>0.05], while the rate of menopausal, BMI(≥25 kg/m~2), the cases coupled with MS, the size of waist circumference (> 80 cm), the level of fasting plasma glucose (≥5.6 mmol/L),TG(> 1.7 mmol/L)and abnormal systolic and diastolic blood pressure in study group were higher than those in control group (67.5% vs. 48. 9%, 45.5% vs. 23.3%, 43.9% vs.18.9%, 50.4% vs. 27.8%, 53.7% vs. 21.1%, 40.7% vs. 21.1% and 40.7% vs. 25.6%,respectively, all P <0.05). The percentage of HDL(< 1.30 mmol/L) was higher in study group than that in control granp(63. 4% vs. 32. 2%, P <0.05). (2) There were not significant difference for the clinical stage, pathological type, grades between patients with or without MS in study group (P > 0.05). (3) The Logistic multivariate survival analysis shown that central obesity, higher TG, lower HDL and abnormal plasma glucose were independent risk factors for endometrioid uterine carcinomas coupled with MS (P< 0.05). Conclusion Metabolic syndrome is marginally associated with an increased risk of endometrioid uterine carcinomas, which may be the new point to screen, prevention and treatment endometrioid uterine carcinomas.
