The Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire was used for appraisal in a newly-built general hospital for all the nursing staff, and they were provided with a six-month safety culture training according to appraisal results.The training has elevated the positive response rate of the nursing staff towards all dimensions of patient safety culture, proving that scientific and reasonable safety culture training is conducive to nurses' perception of patient safety culture.

Objective To investigate the protective effect of propotol against hepatic ischemiareperfusion injury in rats on mitochondrial permeability transition pore (MPTP) and the mechanism of GSK-3β.Methods Thirty SD rats were randomly assigned into five groups (n =6):sham operation group (S group),ischemia reperfusion group (I/R group),CsA pretreatment group (C group),propofol pretreatment group (P group),and propofol plus atractyloside pretreatment group (A + P group).Nauta liver ischemia-reperfusion rat model was used.Liver lobes were subjected to warm ischemia for 60min and then reperfusion for 120 min.In P group,propofol [12 mg/(kg · h)] was administered in the femoral vein for 30 min before ischemia until the end of reperfusion.In C group,CsA (2 mg/kg) was administered in the femoral vein for 20min before ischemia.In A + P group,20 μmol/kg of atractyloside was given through the femoral vein 10min before the injection of propofol.Rats were sacrificed at the end of reperfusion,and venous blood and hepatic tissue specimens from the same part of ischemia were obtained from different groups.Results Compared with S group,the AST and ALT levels were increased significantly,mitochondrial swelling were increased and mitochondrial membrane potential were decreased significantly in I/R group and A + P group.Casepase-3 were increased significantly and p-GSK3β Ser9 were decreased significantly in I/R group and A + P group.Compared with I/R group,the content of AST and ALT were decreased significantly,mitochondrial swelling were decreased and mitochondrial membrane potential were increased significantly,casepase-3 release were decreased significantly and p-GSK3β Ser9 were increased significantly in P group and C group.GSK-3β in each group displayed no significant difference.Conclusions Propofol can significantly reduce hepatic ischemia-reperfusion injury.The protective effect of propofol may be achieved via the inhibition of GSK-3β activation,increased p-GSK-3β Ser9 level,suppressing MPTP opening and decreasing hepatocytes apoptosis.

be diagnosed by imaging examination before operation.The ALT patients with large or symptomatic adrenal lipomatous lesions or preoperatively diagnosed teratoma should be given surgical treatment.

At present, cancer is still one of the most serious threats to human health. Despite the wide application of multiple cancer therapies in clinical practice, the therapeutic effects of most cancers are still far from satisfactory. In recent years, the discovery of regulated cell death may be a good first step on the road to treat cancer. Ferroptosis is triggered by lipid peroxidation of unsaturated fatty acids in cell membrane catalyzed by iron ion. It has been widely concerned as an emerging target for cancer therapy. With the booming of biomedical nanotechnology, ferroptosis as an emerging therapeutic target has attracted extensive attention. Here, we review the advance on the intersection of ferroptosis and biomedical nanotechnology. First, the research background of ferroptosis and nano-preparation as well as the feasibility of ferroptosis-based nano-drug delivery systems (nano-DDS) for cancer treatment are presented and analyzed. Then, the strategies for inducing ferroptosis based on nano-DDS are summarized, mainly including: the promotion of Fenton reaction, the inhibition of glutathione peroxidase 4 (GPX-4) and the restriction of the cysteine-glutamate exchange transporter (system Xc^-). Furthermore, the combination therapy strategies based on biomedical nanotechnology induced ferroptosis are also discussed. Finally, we shine the spotlight on the prospects and challenges of ferroptosis-based nanotherapeutics in clinical application.

This study was aimed to evaluate effect of Qinghua Granules (QHG) on glycometabolism, pancreatic islet function and oxidative stress in type-2 diabetics with heat syndrome. A total of 60 cases of type-2 diabetics with heat syndrome (according to the Syndrome Element Syndrome Differentiation) were enrolled in the clinic of the Department of Endocrinology and Metabolism, Shuguang Hospital Affiliated to Shanghai University of Tradi-tional Chinese Medicine. The average age of enrolled cases was (57.9 ± 6.9) years. Enrolled cases were randomly divided into the treatment group and the control group. The original hypoglycemic plan was continued to use. In the treatment group, QHG was administrated. And in the control group, placebo was given. The administration dosage in both groups was one package per day. The treatment course was 12 weeks. The fasting and postpran-dial (120 min after standard meal) blood samples before and after medication were collected. The main evalua-tion indexes were fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and hemoglobin A1c (HbA1c). The secondary evaluation indexes were homeostasis model assessment (HOMA2-%B, HOMA2-%S, HOMA2%-IR), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), maleic dialdehyde (MDA), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL). The anal-ysis of variance was used in the comparison of efficacy between two groups . The results showed that HbA1c in the treatment group was obviously reduced, and HOMA2-%B was obviously increased. There was no significant changes in the control group ( P = 0 . 044 , P = 0 . 016 ) . In the treatment group , SOD increased obviously , MDA reduced obviously. There was no significant change in the control group. There was difference b etween two groups (P = 0.011, P = 0.049). There was no change on blood lipids or other evaluation indexes. It was conclud-ed that QHG is effective in the improvement of glycometabolism, islet β-cell functions and oxidative stress in type-2 diabetics with heat syndrome .

Objective To improve the diagnosis and treatment ot adrenocorticotropin-independent macornodular adrenal hyperplasia (AIMAH).Methods The clinical data of 17 cases with AIMAH from 2000 to 2011 were analyzed retrospectively,including 3 subclinical AIMAH,10 clinical AIMAH and 4 highrisk AIMAH patient,with common radiological characteristic of bilaterally enlarged adrenal glands with multiple nodules like ginger.The 3 cases of subclinical AIMAH patients presented with decreased serum ACTH,normal or slightly elevated plasma cortisol and urinary free cortisol level,no suppression following 1 mg overnight dexamethasone suppression test and absence of clinical signs of Cushing syndrome (CS).While clinical AIMAH and high-risk AIMAH presented with clinical signs of CS,elevated plasma cortisol and urinary free cortisol level,suppressed serum ACTH,loss of normal circadian rhythm in cortisol secretion and no suppression following the low-dose and high-dose overnight dexamethasone suppression test.Among the 4 cases of high-risk AIMAH,2 cases presented with osteoporosis,2 cases with hepatic dysfunction,3 cases with cardiopulmonary dysfunction,and 4 cases with severe hypertension.Three cases of subclinical AIMAH were treated with symptomatic treatment,10 cases of clinical AIMAH patients with surgical operation,4 cases of high-risk AIMAH patients with ketoconazole and surgical operation.Results Three subclinical AIMAH patients received symptomatic treatment and discharged from hospital with normal blood pressure and blood glucose.During the period of follow-up from 3 months to 3 years,endocrine results were normal.Seven clinical AIM AH patients underwent unilateral adrenal tumor resection plus ipsilateral partial adrenalectomy or total adrenalectomy.CS disappeared completely after 6 to 9 months.Two clinical AIMAH patients underwent simultaneous bilateral adrenalectomy.One case died of adrenal crisis after operation,and the other case presented with adrenal insufficiency but returned to normal after glucocorticoid replacement therapy,no Nelson's syndrome happened during the follow-up for 5 years.One clinical AIMAH patient undertook unilateral adrenalectomy twice by interval,followed by routine corticosteroid replacement therapy.Followed up for 10 years,no Nelson's syndrome happened.Four high-risk AIMAH patients received ketoconazole and then underwent right total adrenalectomy.Cortisol levels returned to normal after 1 to 2 months and during the follow-up for 1 to 3 years,the laboratory examinations maintained normal.Conclusions Different treatment methods should be adapted to different subtypes of AIMAH.For subclinical AIMAH,the principal treatment is symptomatic,and close follow-up with regular adrenal imaging and endocrine examination is required.Surgical operation should be performed when clinical symptoms of AIMAH appear.Medical management is essential for high-risk AIMAH to inhibit the production of cortisol at first.Once these patients could stand the stimulation caused by operation,the adrenal glands should be resected as soon as possible.The unilateral adrenalectomy is an effective treatment for clinical AIMAH.
