Objective To observe clinical effect of treating diabetic peripheral neuropathy with Shuxuetong injection combined herbal oral administration. Methods A total of 51 patients with diabetic peripheral neuropathy were randomly recruited into a control group and a treatment group. The control group was treated with western medicine, and the treatment group was treated with Shuxuetong injection combined with Buyang Huanwu decoction. The clinical effect was observed in both groups after the treatment. Results The total effective rate was 88.5% and 68.0% in the treatment group and the control group respectively. The clinical effect in the treatment group was significantly higher than that of the control group (P＜0.05). Conclusion The effects of Shuxuetong injection combined herbal oral administration on diabetic peripheral neuropathy was better than western medicine.

Objective:To discuss the maintenance and testing method, reduce CT machine fault, ensure the quality of CT machine performance, reduce the use of CT machine cost, increase the use value of CT machine,the better service for the masses and treatment.Methods:Using regular maintenance and inspection, specific Toshiba 64 row CT machine each time the content of maintenance and testing content.Results:Regular service and maintenance are the most effective CT machine performance quality guarantee the most basic method, can avoid 30% to 50% of the machine fault, not only greatly reduce the machine hardware damage failure incidence, software programs or data error of failure rates.Conclusion: The regular maintenance and maintenance is hotly debated in recent years the core content of preventive maintenance, periodic testing is an effective guarantee quality of CT machine performance of necessary measures, called on metrology institute and the centers for disease control and coordinated with the hospital, turn the two detection time about half a year, also accord with the national strong inspection requirements so that the rationality of the quality assurance, to avoid most of the repeated testing of national resources waste.

Objective To investigate the prevalence of depression in maintenance hemodialysis (MHD) patients. Additionally,to explore the relationship between depression and microinflammation,serum zinc levels and malnutrition in MHI) patients.Methods One hundred fifty-seven MHD patients were enrolled in this study.The patients were divided into two groups:depressed patients and non-depressed patients,according to the Beck Depression Inventory.The following data were collected:social factors,biochemical index,serum zinc levels,malnutrition-inflammation (MIS) score and IPI score.Binary logistic regression analysis was performed.Results Symptoms of depression were exhibited by 45.2％ of MHD patients (71/157 ).Symptoms of moderate or severe depression were exhibited by 24.2 ％ of the patients ( 38/157 ).However,signicant differences were shown in age [( 62 ± 11 ) vs.( 50 ± 13 ) years old],MIS score [( 7.2 ± 2.2 ) vs.( 3.3 ± 1.6 ) scores],white blood cell count [( 6.4 ± 1.8 ) × 109/L vs.( 5.8 ±1.5) × 109/L],high sensitivity C-reactive protein (hsCRP) [(9 ±6) vs.(4 ±4) mg/L],hemoglobin [(10.7±1.5) vs.(11.3±1.5) g/L],albumin[(33±4) vs.(37 ±3) g/L],fasting glucose [(6.7±3.5) vs.(5.6±2.1) mmol/L],serum zinc [(8.5±2.6) vs.(10.1 ±2.9) μmol/L] between depressed patients and non-depressed patients ( All P ＜ 0.05 ). Binary logistic regressive analysis revealed that the independent risk factors of depression in MHD patients were their MIS score ( OR =2.908,95％ CI =2.037 -4.151 ),as well as their hsCRP( OR =1.217,95％ CI=1.075 - 1.370),serum zinc and fasting glucose levels(OR=1.315,95％CI=1.039 - 1.664).Conclusions There was a high prevalence of depression in MHD patients.Depression is also highly correlated with microinflammation,serum zinc levels,and malnutrition.MIS scores,hsCRP,serum zinc levels and fasting glucose levels.

Objective To investigate prevalence of metabolic syndrome (MS) and its related factors in patients with maintaining hemodialysis (MHD). Methods A total of 162 cases on MHD in Beijing Chaoyang Hospital during June to December 2010, were enrolled in this study and divided into MS group and non-MS group according to the diagnostic criteria for MS set by the International Diabetes Federation. Anthropometric and blood biochemical characteristics of the two groups were compared with t-test and x2 test Risk factors for MS were explored with binary logistic regression analysis. Results Prevalence of MS was 40. 7% (66/162) . There was significant difference found in body mass index [(24. 2 ±3. 1) vs. (21. 6 ±2. 7) kg/m2], waistline circumference[(93 ±8) vs. (79 ±7)cm] , white blood cell count [(6. 8 ± 1. 5) × 109/L vs. (5. 6 ± 1. 4) × 109/L] , hypersensitive serum C-reactive protein [(7 ± 5)vs. (4 ±3) mg/L], high-density lipoprotein-cholesterol [(0. 99 ±0. 26)vs. (1.39 ±0.39) mmol/L], low-density lipoprotein-cholesterol [(2. 5 ± 0. 8) vs. ( 2. 1 ± 0. 7) mmol/L], triglyceride ( TG) [( 2. 1 ±1.1 )vs. (1.3±0.8) mmol/L], fasting blood glucose [(5.9±2. 7)vs. (4.8±1.3) mmol/L], serum level of iron [(16±7)vs. (13 ±5) μmol/L], uric acid [(429±114) vs. (388±88) (μmol/L], and carbon dioxide combining power (CO2CP) [(22 ±4)vs. (23 ±4) mmol/L]between MS group and non-MS group (All P < 0.05 ) . But there was no significant difference found in subjective global assessment of nutritional status (SGA) , thickness of skin fold of the triceps muscle (TSF) between the two groups (Both P > 0.05). Binary logistic regressive analysis revealed that serum level of iron (OR = 1.058,95% CI = 1.001 -1. 119), white blood cell count ( OR = 1. 786,95% CI = 1. 346 - 2.371) and hypersensitive serum C-reactive protein (OR = 1. 101,95% CI = 1.010 - 1.201 ) were independent risk factors for MS in MHD patients. Conclusions Morbidity of MS is high in patients with MHD, involved with inflammation process. Serum level of iron, white blood cell count and hypersensitive serum C-reactive protein are independent risk factors for MS in patients with MHD and no inevitable connection between MS and nutritional status in them is found.

Aim To investigate the effects of TSG on the content of nitric oxide and the expression of endo-thelium nitric oxide synthase in artery vessels of experimental atherosclerotic rats.Methods Sixty male rats were randomly divided into six groups.GroupⅠ,Normal control;GroupⅡ,Model control;Group Ⅲ,TSG low dose;Group Ⅳ,TSG middle dose;GroupⅤ,TSG high dose;group Ⅵ,Simvastatin.After 12 weeks,blood samples were collected from carotid arteries of rats,and the levels of NO in serum were measured.After that,the aortas were separated from the bodies and placed in-70℃,then the content of nitric oxide synthase was detected,and gene expression of eNOS and iNOSmRNA in artery vessels were respectively measured with RT-PCR method.STATA 8.0 software was adopted in date analysis..Results compared with those of the model group,the level of NO,the activity of NOS and the gene expression of eNOS were increased,and the gene expression of iNOS was reduced by simvastatin and TSG 30,60,120 mg?kg-1?d-1 in the high cholesterol-fed rats,which showed a dose-dependent effect.Conclusion TSG can enhance the expression of eNOS gene and reduce the expression of iNOS gene in aorta vessels of experimental atherosclerotic rats,which may be one of the anti-atherosclerosis mechanisms of TSG.

Objective To explore the mechanism and way for CT10 regulator of kinase like (CRKL) involving in drug resistance in leukemia cells. Methods The four major proteins included Ras protein, signal transducer and activator of transcripton 5 (STAT5) protein, phosphoinositide 3-kinase (PI3K) protein and paxillin protein in leukemia which involved in signal transduction pathway of CRKL. The expressions of those proteins were detected by Western-blot and immunofluorescent staining and confocal laser scanning microscopy. Results Compared with K562/S cells, the expressions of Ras(41.52±15.47 vs. 23.74±8.67) and PI3K (35.60±12.48 vs. 10.09±0.005) protein were up-regulated in K562/ADM cells (t=3.01,6.13;both P<0.05), while there were no significant changes in the expressions of paxillin (20.10±11.89 vs. 23.11±12.40) and STAT5 protein (25.72±14.46 vs. 17.58±9.21) between K562/S cells and K562/ADM cells(t=0. 18,1.43;both P>0. 0S). Conclusions Ras and PI3K protein may play a role in the multidrug resistance of K562 cell line, while paxillin and STAT5 protein may be not involved in the formation of resistant in K562 cells.
