ABSTRACT
Objective To compare and analyze the causes that occurred in psychiatric and general department using SHEL models, in order to provide evidence of preventing nursing adverse events.Methods We analyzed causes of 136 nursing adverse events using SHEL models, and compared the classification, causes, incidence of nursing adverse events between psychiatric and general departments. Results The first three nursing adverse events in psychiatric department were medication error,going outside, suicide and self harm, and those in general department were medication errors, specimens being wrong, improper operation and pipeline off. 91.18% of nursing adverse events accounted for quality of nursing services, 43.38% accounted for nursing environment, 41.18% accounted for clinical environment,and 57.35% accounted for parties and others. Incidence of nursing adverse events in psychiatric department were higher than that in general department. Conclusions SHEL model can objectively and comprehensively analyze the causes of nursing adverse events, and make nursing managers take the appropriate management strategy and the best safeguard against the risk of development of response.
ABSTRACT
Objective To investigate the relationship between lipid abnormality and benign prostatic hyperplasia (BPH) in men receiving physical examination. MethodsFour hundred and one people who participated health examination in our hospital in May 2008 were included in the study. They were divided into two groups according to history of disease, IPSS score, the results of digital rectal examination and transrectal ultrasound: BPH group (192 cases) and no BPH group (209 cases). The blood lipid level and risk factors were compared in two groups. ResultsThere were no statistical differences in blood lipid level and risk stratification of cardiovascular disease between the two groups (TG:P=0. 698;TC:P=0. 654;LDL-C:P=0. 880; HDL-C:P=0. 531; risk stratification: P= 0. 251). IPSS score had no obvious correlation with blood lipid level (TG: P = 0. 054 ; TC: P =0. 149; LDL-C: P = 0. 427; HDL-C:P=0. 193) .Conclusions BPH complicated with lipid abnormality is common in the clinics, but the correlation between BPH and lipid abnormality in patients with light BPH is not so clear as that in patients with mild or severe BPH.
ABSTRACT
Objective To explore how does chymase affect diabetic cardiomyopathy by investigating the gene expression of chymase and the relationship between the gene expression of chymase and the angiotensin Ⅱ in the cardiomyopathy of streptozotocin-induced diabetic hamasters. Methods Diabetic hamsters were induced by intraperitoneal injection of STZ 40 mg/kg once a day for 3 days. After stabilization of diabetic state for 18 weeks, the myocardial ultrastructure was observed with electron microscope and pathologic changes were observed by light microscopy. Immunohistochemistry was used to measure the level of expression of type Ⅰ and type Ⅲ collagen in diabetic and normal hamster hearts. Level of blood glucose, lipoprotein was determined using biocehemical methods. Apoptosis of cardiomyocyte was measured using TUNEL methods. Radioimmunuoassay method was used to determine the level of angiotensin Ⅱ. RT-PCR was used to determine chymase gene expression (corrected by?-actin). ResultsComparing with the control group, levels of serum glucose, TG, TC, LDL in DM group were much higher. Concentrations of collagen Ⅰ, Ⅲ and angiotensin Ⅱ [(95.8?16.0)?g/kg tissue vs (51.1?20.8)?g/kg tissue] in myocardial tissue in DM group were much higher than those in control group. RT-PCR result showed: Comparing with the control group, the mRNA expression of chymase in DM group was promoted significantly (0.810?0.026 vs 0.490?0.087). Conclusion In diabetic hamsters, the gene expression of chymase were much higher than thatin the control group, accompanying higher level of Angiotensin Ⅱ, higher levels of expression of collagen Ⅰ and Ⅲ. This result suggests that chymase plays an important role in the diabetic cardiomyopathy by promoting the activity of chymase.
ABSTRACT
Objective To investigate the change of renal 1-alpha hydroxylase and its effect on bone mineral density in the old rats with type 2 diabetic nephropathy. Methods Forty Wistar rats of 18 months old were randomly divided into normal control (N), diabetes (D), diabetes treated with vitamin D_ 3 (T1) and diabetes treated with 1-?(OH)D_ 3 (T2) groups, respectively. Ten rats in each group. Dual energy X-ray absorption (DEXA) was used to determine bone mineral density (BMD) of lumbar spines and femoral bone. 24 h urinary protein excretion, serum 25(OH)D_ 3 and 1,25(OH)_ 2 D_ 3 were measured by radioimmunoassay. Results Compared with controls, 24 h urinary protein excretion increased remarkably D, T1, T2 groups, while BMD greatly decreased, much lower in D group and T1 group than T2 group (P0.05). The level of 1,25(OH)_ 2 D_ 3 in N group was the same to T2 group, but higher than D, T1 groups (P
ABSTRACT
Objective:To observe the change of myocardial cell and matrix in the rats with type 2 diabetes and to approach the construction method of diabetic cardiomyopathy models in wistar rats with type 2 diabetes mellitus.Method:Sixteen wistar rats of 6 months were randomly divided into normal group(N)and diabetic group(D),with eight rats in each group.Euglycemic insulin clamp technique(EICT)was used to determine insulin resistance(IR).Heart weight(HW)and body weight(BW)of each rat were measured to ratio HW and BW,The apoptosis of myocardial cell was evaluated by TUNEL.,and the ultramicrostructure of.myocardial cell and construction of heart were observed.And immunohistochemistry (SABC method) was used to measure the level of Ⅰand Ⅲ types of collagen protein.Results:compared with group(N),GIR of group(D) was remarkably lower(P
