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.

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

OBJECTIVE:To explore the characteristics and rules of adverse drug reactions (ADR) of ciprofloxacin,and pro-vide reference for clinical rational drug use. METHODS:Usingciprofloxacinandadverse drug reactionsas key words,the lit-eratures reported in Wanfang database in 1998-2015 were retrieved,the gender,age,route of administration,the original disease, ADR occurrence time,ADR involving organs/systems,the main clinical manifestations,allergies,prognosis and outcome were sta-tistically analyzed. RESULTS:Totally 181 valid literatures were retrieved,involving 213 patients. Male was more than female (57.28% vs. 42.72%);it mainly occurred in the first day(130 cases,61.03%);intravenous injection(179 cases,84.04%)was the main administration route;the main ADR involving organs/systems were systemic damage(71 cases,33.33%)and nervous sys-tem damage(50 cases,23.47%);the main clinical manifestations were anaphylactic shock(65 cases,30.52%),severe cases can cause death (3 cases,1.41%). CONCLUSIONS:The clinic should strictly master the ciprofloxacin indications,use rationally, give close observation to the course of medication,alert the incidence of ADR.

Objective To explore the factors that may influence the compliance of medical workers in dealing with classifying medical wastes. Methods One hundred and sixteen medical workers participated in this investigation by applying self-designed questionnaire and live observation mode. Influential factors were evaluated by multi-factors analysis. Results The compliance percent of 116 medical workers was only 69.9%(351/502), which caused by low awareness of medical wastes. As much as 20.12 % (101/502) medical workers made mistakes when dealing with infectious wastes. Working experience, awareness of medical wastes, instruments and working load were associated with compliance of medical workers (P<0.05). Conclusions Low compliance of medical workers dealing with medical wastes were related to lacking working experience, low awareness of medical wastes, inappropriate instruments and heavy working load. In this case, improving management system of medical wastes, regular training and assessment, adding instruments and identification of medical wastes, increasing medical workers and simplifying the working process are effective approaches in increasing compliance of medical workers in dealing with medical wastes and improving quality of nursing management.

Objective To assess the clinical efficacy of modified split patella in the treatment of patellar fracture.Methods 56 patients with patellar fracture were selected,and they were divided into two groups according to the random number method.The regular group was treated with common split patella,while the improved group was treated with modified split patella.In both two groups,the aspects of split patella slip,model large and knee pain were recorded.Results The incidence rates of model large and knee pain in the improved group were 3.57%,7.14%, which were 25.00%,32.14%in the regular group,the differences were statistically significant(χ2 =5.250,5.543,P=0.022,0.019).The incidence rate of split patella slip in the regular group was 3.57%,that was 0.00% in the improved group,the difference was statistically significant(χ2 =1.018,P=0.313).Conclusion Modified split patella mini-mizes the incidence of split patella model large and patellofemoral osteoarthritis.Thus,it deserves further application.

Poor communication between medical staff and patients is the main cause of medical disputes,and the clear emotional recognition and reasonable response of the patient needs psychology training and practice.Balint groups can create a good support environment and is an effective way to improve the communication ability and professional growth for medical staff.

Objective To evaluate the value of echocardiography in the evaluation of congestive heart failure (PHC) in peripartum cardiomyopathy patients.Methods 64 patients with congestive heart failure were randomly divided into two groups.The control group were treated with routine therapy.The study group were treated with levocarnitine in combination with routine therapy.Echocardiography was performed before and after treatment, and the changes of each index were compared.Results There was no significant difference in left ventricular end diastolic diameter, left ventricular ejection fraction and cardiac output between the two groups before treatment.After treatment, the left ventricular end diastolic diameter, left ventricular ejection fraction and cardiac output in study group after treatment were higher than those in control group(P<0.05).There was no significant difference in left ventricular short axis shortening, left ventricular end-systolic diameter and stroke volume between the two groups before treatment, but the left ventricular short axis shortening and stroke volume in study group after treatment were higher than those in control group (P<0.05), the left ventricular end-systolic diameter was lower ethan that in control group ( P<0.05 ) .The treatment effect of the study group was significantly higher than that in control group (P<0.05).The adverse reactions was significantly lower than that in the control group (P<0.05).Conclusion L-carnitine is effective in the treatment of heart failure in peripartum cardiomyopathy patients.It can be used to evaluate the therapeutic effect of cardiac ultrasound in order to provide guidance for clinical treatment.
