Results The positive rates of serum HE 4 in ovarian cancer group , ovarian benign tumor group and healthy group were 86.0%,5.5%,2.0%.The positive rate of serum HE4 in ovarian carcinoma was significantly higher than that in benign ovarian tumor group and the healthy group (χ2 =31.06,30.82,all P<0.01).The positive rates of serum YKL-40 in ovarian cancer group ,ovarian benign tumor group and healthy group were 82.0%,3.3%,2.0%.The positive rate of serum YKL-40 in ovarian carcinoma was significantly higher than that in benign ovarian tumor group and the healthy group(χ2 =30.92,32.06,all P<0.01).Serum HE4 in the diagnosis of ovarian cancer ,the sensitivity was 86.0%,specificity of 95.7%,accuracy of 91.7%.Serum YKL-40 in the diagnosis of ovarian cancer ,the sensitivity was 82.0%,specificity of 97.1%,accuracy of 90.8%.For the joint detection,the sensitivity for diagnosis of ovarian cancer was 92.0%,and the specificity was 93.6%,accuracy was 95.0%,higher than those of the single detection . 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.

ObjectiveTo study the optimized security strategy for informing cancer patients with the disease,and let patients be fully informed and even more actively cooperate with doctors while they are under treatment.MethodsGrouped with adversity quotient (AQ) score,these cancer patients were in comparison with those who had been informed by other ways without support strategy,and different groups of patients were estimated in different strategies in accordance with self-rating anxiety scale (SAS) and self-rating depression scale (SDS).Results With certain strategies,high and low AQ score groups' SAS and SDS scores stably restored in 1 day to 1 week,and the differences had statistical significance(P ＜ 0.01 ).The patients were well-informed without any difficulty and actively cooperated with treatment.No related factors led to self-mutilation,suicide and other serious incidents.While the SAS and SDS scores of the control group who were not informed by the strategy were not satisfactorily recovered,and the patients could not actively cooperate with the doctors.Especially being notified after 1 d to 1 week,the SAS and SDS scores had no significant improvement,and the differences had no statistical significance compared with themselves ( P ＞ 0.05 ).It is difficult to avoid the occurrence of serious incidents.Conclusion Based on AQ score,it is safe and effective to inform cancer patients of their disease condition by individual strategies.It not only respects patients rights,but also gains the active cooperation of the patients,and is helpful for treatment with minimizing adverse effects.

OBJECTIVE To explore the risk factors of lung infection in eldly paitents with hip fracture(≥80 years).METHODS A total of 119 cases of hip fracture treating with surgery from Jan 2004 to Jan 2007 were analyzed retrospectively.RESULTS There were 36 cases of hospital lung infection(infection rate of 30.25%) and 7 death cases(19.44%).It was found that senior age,invasive operation,abuse of antibiotics and previous history involved were the main factors causing hospital lung infection.CONCLUSIONS The effective measures to reduce hospital lung infection among elderly patients with hip fracture include environment management and infection monitoring,strictly hand-washing,cross-infection prevention,rational antibiotics usage and active treatment of underlying diseases.

Objective To observe epidemic status and the types of the influenza virus, to analyse influenza epidemic trends in Tianshui City, and to provide basis for influenza prevention and control. Methods Throat swab specimens of influenza cases in pilot hospitals and area of influenza-like a typical outbreak in Nov. 2005-Oct. 2008 was tested by chicken embryo and MDCK cells.The identifi cation of the isolates was carried out by hemagglutination and hemagglutination inhibition test. The separation of strains were sent to the National Influenza Center to conduct a review appraisal. Results 1819 throat swab specimens of influenza-like were collected and 247 were isolated. Isolation rate was 13.58%. There were 36 strains (14.57%) of A (H1N1) subtype, 75 strains (30.36%) of A (H3N2) subtype and 136 (Victoria department 121, Yamagata department 15) strain (55.06%) of B subtype. Conclusion There were three epidemic types of influenza virus types-A (H1N1), A (H3N2) and B in Tianshui. Virus were epidemic at the same time or alternating at different intensity in different years. Outbreaks of influenza have occurred in rural primary and secondary schools, and B subtype was dominating.

OBJECTIVE To survey the status quo of hospital infection management and countermeasures in township health center. METHODS To adopt a unified examination and assessment survey,the township hospital infection management,including organization,personnel training,monitoring,disinfection and isolation,occupational protection,sterile disposable medical supplies and medical waste management was investigated in 15 Lanxi Town ship Health Centers. RESULTS Only 2 centers had management organizations (13.33%),5 (33.33%) to participate in personnel/training,no one carry out the monitoring of hospital infection,with fuzzy concept about cleaning disinfection and sterilization and poor awareness of occupational protection. CONCLUSIONS Realizing a sound organization improving hospital infection management staff and intensive training,increaseing the investment and strengthening th supervision and inspection are in accordance with the law and guide management of patients in rural areas to be assured of a secure medical establishment.
