Objective To investigate the curative effects of fluvastatin and its anti-inflammation mechanism in early diabetic nephropathy (EDN).Methods 140 patients with EDN were randomly divided into two groups,the control group (n=70) and the treated group (n=70).The control group received conventional therapy,while the treated group was added oral 40 microgram of fluvastatin every night.Compare the UAER,Scr and CRP 3,6 and 9 months later respectively.Results UAER and Scr had been decreased more significantly and quickly(three months earlier) in treated group than in control group. CRP had been decreased significantly in treated group,while no significant decrease had been found in control group during the follow-up of nine months.Furthermore,similar results were also obtained in those EDN with normolipidemia when further analyzed.Conclusion Fluvastatin can ameliorate microalbuminuria and improve renal function by its anti-inflammation effect by decreasing CRP,which is independent of its lowering lipidemia effect.

Objective To investigate the level of self-concept on occupation among junior nurses.Methods One hundred and thirty-nine nurses with nursing experience of 1-5 years were involved in the survey by using the Nurses' Self-Concept Questionnaire (NSCQ).Comparisons were done between the groups of nurses with undergraduate education and those with three-year training courses in terms of self-concept and its dimensions.Results The total score of junior nurses on self concept was(5.33±0.77).The score of the nurses with undergraduate education was(5.16±0.88),significantly lower than the score of(5.44±0.71)of the nurses with three-year training courses(P<0.05).Conclusion The nursing administration should attach importance to the self-concept on occupation, instructing specially the nurses with undergraduate education so as to enhance their mental health and their self-identification of nursing as an occupation.

BACKGROUND:Medical polyethylene glycol berberine is a biomaterial against tissue adhesion, with anti-inflammatory effects, which can prevent scar formation and reduce local inflammation. OBJECTIVE:To observe the clinical efficacy of medical polyethylene glycol berberinevia shoulder joint injections on subacromial impingement syndrome. METHODS:Forty patients with subacromial impingement syndrome I, II were voluntarily divided into two groups: biomaterial group (n=20), single intra-articular injection of 3 mL medical polyethylene glycol berberine; conservative treatment group (n=20), single subacromial space closed treatment of betamethasone combined with lidocaine hydrochloride folowed by oral administration of celecoxib 200 mg once, twice a day, totaly for 1 week. Patients were folowed up clinicaly for visual analog scale scores, range of motion of the shoulder and the American Shoulder and Elbow Surgeons scores. RESULTS AND CONCLUSION:Both of two groups had a great improvement in visual analog scale scores, range of motion of the shoulder and the American Shoulder and Elbow Surgeons scores after treatment (P< 0.05), and these scores were improved more significantly in the biomaterial group than the conservative treatment group at 2 weeks, 4 weeks, 3 months, 6 months after treatment (P < 0.001). These findings indicate that the intra-articular injection of medical polyethylene glycol berberine for subacromial impingement syndrome can effectively aleviate shoulder pain, improve shoulder mobility, and promote functional recovery of the shoulder.

Aim To explore the effects of Nrf2-ARE signal path on levrtiracetam anti-epileptic and levrtiracetam on learning and memorizing ability.Methods Thirty-six SD rats were divided into normal saline group, levrtiracetam group, model group and treatment group.Each group recruited nine rats.Tests of Morries water maze were given to the rats to evaluate their learning and memorizing ability.The protein expression of nuclear factor (erythroid-derived2)-like2 (Nrf2), heme oxygenase 1(HO-1) and NAD(P)H quinone oxidoreductase(NQO1) were examined by Western blot.Results Compared with model group, levrtiracetam could shorten the plateau period in epileptic rats (P<0.05), and increase the expression of Nrf2 protein, HO-1 protein and NQO1 protein in hippocampus(P<0.05).Conclusions Levrtiracetam could improve the learning and memorizing ability in epileptic rats.Levrtiracetam may increase the expression of HO-1 protein and NQO1 protein through the Nrf2-ARE pathway and play a part in antiepileptic effects.

Objective To observe the biological characteristics of db/db mice, and to provide the basis for application of db/db mice in experimental research.Methods Spontaneous type 2 diabetes BKS.Cg-Dock7m +/+ Leprdb/JNju mice and wild type mice of the same age were used in this study.Their fasting blood glucose was determined at 8,12,16, 20 and 24 weeks of age, the body weight was recorded at 10, 12,16, 20 and 24 weeks of age, the levels of serum insulin, total cholesterol and triglyceride were measured, the organ weight and liver coefficient were determined, and the liver and pancreas were taken for pathological examination at 24 weeks of age.Results The db/db mice maintained a high level of fasting blood glucose and body weight.Levels of serum insulin, total cholesterol, and triglyceride were significantly higher than the wild type mice.Compared with wild type mice, liver weight and kidney weight were also significantly increased.Obvious pathological changes of liver and pancreas were observed in 24-week old db/db mice.Conclusions db/db mouse has obvious characteristics of type 2 diabetes, such as hyperglycemia, hyperlipidemia, and hyperinsulinemia, can maintain stable levels of high blood glucose,and is an ideal animal model for experimental study of type 2 diabetes mellitus.

Objective To explore the effects of extracellular regulated protein kinase 1/2 (ERK1/2) signal pathway on cardiomyocyte apoptosis and tumor necrosis factor-α (TNF-α) expression at different glucose-lowing rates,and the influence of glucose-lowing rate on cardiomyocyte injury and inflammatory secretion function,as well as its mechanism.Methods Cardiomyocytes of Wistar neonate rat were maintained in medium supplemented with 25 mmol/L glucose for 72 h.Then the medium was changed to different concentrations of glucose and all cells were divided into five groups.Group A was control group whose medium supplemented with 25 mmol/L glucose.Medium of group B,C,D,E was supplemented with 20,15,10,5 mmol/L glucose (glucose-lowing rate was 5,10,15,20 mmol/L) respectively.Survival rate of cardiomyocyte was measured by CCK8 kit.Cardiomyocyte apoptosis was measured by flow cytometry instrument and laser confocal microscope after Annexin V-PI.TNF-α was measured by ELISA.ERK1/2 protein and phosphorylation were measured by Western blot.Cardiomyocyte apoptosis and TNF-α levels were measured again after U0126 was added.Results At the same time point,along with the glucose-lowing rate increased,survival rate of cardiomyocyte in group A was increased and those in group C,D,E were decreased (P＜ 0.05).TNF-α concentration was increased in group B,C,D and decreased in group E.After 24 h,apoptosis rate decreased in group B and increased in group C,D,E (P＜0.05).ERK1/2 phosphorylation level increased in group B,D,and E(P＜0.05).The ERK1/2 phosphorylation level in group B was the lowest.After U0126 was added,survival rates of cardiomyocyte in all groups were increased (P＜0.01) while TNF-α concentrations were decreased (P＜0.05).In every group,survival rate of eardiomyocyte after 48 h was lower than that after 3 h and 24 h,while TNF-α concentration was higher (P＜0.05).Conclusion Influence of glucose-lowering rate for cardiomyocyte apoptosis and TNF-o is caused by ERK1/2 pathway.In the glucose-lowering course,ERK1/2 pathway promotes cardiomyocytes apoptosis and TNF-α secretion is related with not only osmotic pressure,but also ERK1/2 signal pathway activation as well.

Objective To investigate the antitumor effect of 17aα-D-homo-ethynylestradiol-3-acetae on the mice transplanted with melanoma (B16) tumor cells,and to explore the possible synergistic effect with irradiation.Methods IRM-2 mice transplanted with B16 cells were randomly classified into control group,irradiation group,17aα-D-homo-ethynylestradiol-3-acetae drug ( high dose,medium dose,low dose) groups,and drug and irradiation combination group.Mice in drug group and the combination group were intraperitoneally injected with 5,7.5,and 10 mg/kg drug for 7 days.Mice in the irradiation and combination group received 1 Gy total body irradiation at 4 d after drug injection and then once a day for 5 days.The tumor inhibition efficiency,the number of bone marrow cells,thymus indices,and spleen indices were evaluated.Results Tumor weights in each drug group were significantly lower than those of the control( t =4.58,9.07,6.67,P ＜ 0.05 ).Drug combinated with 137Csγ-rays enhanced the antitumor effect so that the tumor weights in the combination group were significantly decreased ( t =8.06,10.35,6.71,P ＜0.05 ) in comparison with the control groups.Moreover,the numbers of marrow nucleated cells,thymus index and spleen index in the drug group were higher than those in the control group ( t =2.64,3.80,2.84,P ＜ 0.05 ).Conclusions 17aα-D-homo-ethynylestrudiol-3-acetae can inhibit cell growth of B16 melanoma in mice and may also have radioprotective effect on the hematopoietic system and immune system of mice.

This study is to investigate the protective effects of the SB203580 against radiation induced mortality and intestinal injury of mice. A total of 67 male C57BL/6 mice (20.0-22.0 g) were matched according to body weight and randomly assigned to one of three groups: control, total body irradiation exposure (IR, 7.2 Gy) only, and IR (7.2 Gy) + SB203580 (15 mg x kg(-1)). 30 days survival rate was observed in the experiment. In intestinal injury experiment, the expression levels of caspase-3, Ki67, p53 and p-p38 were assayed in the mice intestine crypts. The results showed that the 30 days survival rate was 100% (control), 0 (IR) and 40% (IR+ SB203580), separately. Compared to the IR groups, the positive cells of caspase-3, p53 and p-p38 in crypt cells decreased 33.00%, 21.78% and 34.63%, respectively. The rate of positive cells of Ki67 increased 37.96%. Significant difference was found between all of them (P < 0.01). SB203580 potently protected against radiation-induced lethal and intestinal injury in mice, and it may be a potential radio protector.
