Conclusion Combined with serum HE 4 and YKL-40 detection can significantly improve the diagnostic accuracy of ovarian cancer patients .

BACKGROUND:Occurrence and development of diabetic complications is closely related to the severity of oxidative stress imbalance in the body. OBJECTIVE:To investigate the effect of embryonic stem cel s on oxidative stress response of rats with diabetic nephropathy. METHODS:Primarily cultured rat embryonic stem cel s were observed for cel morphology and surface antigen detection. Sprague-Dawley rats were divided into experimental group (two injections of embryonic stem cel s via the tail vein), model group (injection of the same volume of PBS), and normal control group (with no modeling, intraperitoneal injection of sodium citrate-citrate buffer). In the former two groups, the rats were intraperitoneal y injected sodium citrate-citrate buffer diluted streptozotocin to establish diabetic nephropathy models before treatment. At 5 weeks after the last injection, blood glucose level, renal function indicators (urine protein/urine creatinine, blood urea nitrogen and serum creatinine) were tested in each group;contents of malondialdehyde and protein carbonyl were detected in the kidney;the expression level of superoxide dismutase was detected by western blot assay. RESULTS AND CONCLUSION:The embryonic stem cel s were oval or round, with clear boundary and good refraction, and highly expressed Oct-4 and SSEA-1. Compared with the control group, renal biochemical indicators, malondialdehyde and protein carbonyl contents were significantly increased, while the expression level of superoxide dismutase was decreased dramatical y in the model group and experimental group (P<0.05);compared with the model group, the renal biochemical indicators, malondialdehyde and protein carbonyl contents were dropped significantly in the experimental group, but the expression of superoxide dismutase was significantly rebounded (P<0.05). Taken together, embryonic stem cel s can reverse the occurrence and development of diabetic nephropathy by inhibiting oxidative stress in progress.

BACKGROUND: Understanding of patch classification, characteristics, and reaction with host is necessary for best selection of reparative surgery materials.OBJECTIVE: To summarize the patch classification, characteristics and its application in pelvic reconstruction, as well as the complications.METHODS: A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net/index.htm) was performed for related articles with the key words "patch, polypropylene, compound patch" in Chinese and "reconstructive pelvic surgery, repair, replacement" in English. Articles regarding patch classification, characteristics biocompatibility, and application effect, or in the same circle published recently in authoritative journals were included. A total of 24 articles were finally selected.RESULTS AND CONCLUSION: Polypropylene patch is weaved network, with large mesh, which allows for fiber tissue ingrowth and improves tissue intensity and tensile strength. Leukocyte and macrophage can enter the mesh, so the patch has good anti-infection ability. Expanded polytetrafluoroethylene is soft and smooth, with good tissue tolerance, and can prevent affixion with intraabdominal tissues. Moreover, the submicron pore diameter prevents bacteria invasion. The inflammation and foreign body reaction induced by the expanded polytetrafluoroethylene is the most slight among artificial synthetic materials.

Objective To study the relation between diabetic rat encephalopathy and hippocampal apoptosis, and the therapeutic effect and mechanism of Ginkgo biloba extract. Methods Sixty rats were assigned into control group(NC), diabetic encephalopathy group (DM+B) and EGb-treatment group (EGb) randomly, and every group was further divided into two time points of 1 month (NC_1 ,DM+B_1, EGb_1 ) and 3 month(NC_3 ,DM+B_3, EGb_3 ). The behavioral abnormalities were investigated by water maze test and the apoptosis levels of brain tissue by ELISA. Immunohistochemistry and RT-PCR were performed to determine the protein and mRNA expressions of Bcl-2 and Bax. Results (1) Mild dysfunction of learning and memory was detected in DM+B_1 group, and the dysfunction became worse in DM+B_3 group. The matters were greatly improved in EGb-treatment groups. (2) The expressions of Bcl-2 protein and mRNA were increased in DM+B_1 and DM+B_3 groups, and were stronger in EGb_1 and EGb_3 groups. (3) The expressions of Bax protein and mRNA were obviously increased in DM+B_1 and DM+B_3 groups, and were dramatically reduced in EGb_1 and EGb_3 groups. (4) Compared with control group, the apoptosis level of brain tissue was increased in DM+B_1 group, and obviously greater in DM+B_3 group. In the EGb-treatment groups the levels were dramatically reduced. Conclusions Diabetic encephalopathy may be closely related to hippocampal apoptosis. EGb has an protective effect and the mechanism may be attributed to its effects inhibiting apoptosis.

Objective To explore the characteristics, related risk factors and prognosis of cervical carcinoma in elderly women. Methods 163 cases with stage Ⅰ-Ⅱ cervical carcinoma according to International Federation of Gynecology and Obstetrics (FIGO) criteria underwent radical hysterectomy and pelvic lymph dissection from January 1997 to December 2006. They were divided into aged group, adult group and young group. The clinical pathological data, prognosis and recurrence were retrospectively analyzed. Results The prevalence rate of stage Ⅱ cervical carcinoma was 78.7% (37/47) in aged group, 61.7 % (58/94) in adult group and 59.1% (13/22) in young group. The prevalence difference was statically significant. The prevalence rate of non-squamous cell carcinoma was 8. 5 % (4/47) in aged group, which was higher than that in adult group [5.3%(5/94)]and lower than that in young group [18. 2% (4/22)] (P<0.05). In aged group, pathological grading were 78.7% (37/47) of middle differentiation and 4. 3% (2/47) of low differentiation(P<0. 01). The rate of lymph node metastasis was 8. 51% (4/47)in aged women, 27.7 % (26/94) in adult women and 40.90% (9/22) in young women (P<0. 01). The recurrence rate was similar among the three groups. The death rate was 85.7% in overall recurrent cases, (12/14)in aged group, 73.1% (19/26)in adult group and 50.0% (4/8)in young group, and there was no significant difference (P=0. 193). Conclusions Cervical carcinoma in elderly women has a later clinical stage, higher prevalence of non-squamous cell carcinoma, more middle differentiation tumour tissues and fewer lymphatic metastasis, which can provide evidence for clinical diagnosis and treatment.
