Objective To investigate the insulin dosage and analyze the dosage-impacting factors of intensive insulin treatment in Chinese type 2 diabetic patients.Methods Totally 1025 patients with intensive insulin treatment were included,the insulin dosage and clinical characteristics were taken down and analyzed.Results The mean insulin dosage was 39.30U/day,the insulin dosage per kg of body weight was 0.61U/Kg,among which the dosage of intermediate-acting insulin was 9.79 U/day,occupying 25.24%,while the pre-meal one was 29.51 U/day,occupying 74.76%.According to the insulin dosage per kg of body weight,patients were divided into low dosage group and high dosage one.The result showed significant difference in period of diabetes,BMI,HbA1c,and the highest weight level between the two groups.Correlation analysis showed that the average insulin dosage per kg of body weight was positively correlated with period of diabetes,HbA1c,fasting glucose level and LDL-C,while negatively correlated with BMI,fasting and postprandial C-peptide,the highest body weight level and HDL-C.Conclusions The average insulin dosage for type 2 diabetic patients is 39.30U/day,among which the dosage of intermediate-acting insulin occupies 25% while the pre-meal one occupies 75%.The insulin dosage is positively correlated with period of diabetes and HbA1c,while negatively correlated with BMI and the highest body weight level

Objective To investigate the prevalence and risk factors of diabetic retinopathy(DR) in Chinese elderly diabetic patients. Methods One hundred and ninety patients with type 2 diabetic aged 60 years and over,including 93 males and 97 females were selected.The average age was 68.9 years and the average diabetic duration was 11.5 years.HbA1c,insulin,C-peptide and other clinical characteristics in all patients were tested.The retinopathy of the patients were examined by the retina-camera. Results There were 103 patients without deabetic retinopathy,59 patients carrying nonproliferative deabetic retinopathy and 28 patients carrying proliferative diabetic retinopathy.The above three groups had statistically different diabetic duration((121.1?93.2) vs(149.6?112.1) vs(182.2?83.5)months,P

ⅳ Hydroxyl scavenger, mannitol, in the dosage of 1.1mol/L 2g/kg and 3g/kg could increase LD_(100) of ouabain on guineapigs from 298.54?33.30 ?g/kg to 367.44?44.58 ?g/kg (P

Objective:Screening out NPC from susceptable crowd by serological test for EB virus.Methods:Checking antibody of EB virus by ELISA. At first, EBNA1 IgA was detected for susceptable crowd as a primary screening index, secondary , EBNA1 IgG and Zta IgG were detected in the EBNA1 IgA positive group.Results:The sensitivity and specificity of EBNA1 IgA were 91.8% and 91.4%, both were higher than those of EBNA1 IgG and Zta IgG; the sencondary detection of EBNA1 IgG and Zta IgG raised the specificity of NPC screening to 96.5% and also helped to divide the crowd into 3 groups as high, median, and low risk. And the high risk group accounted for 0.39%.Conclusion:Two-stage screening of NPC raise the sensitivity and specificity of NPC detection. It also helps to divide the crowd into 3 groups of risk.

The models of Cardiacglycoside-induced cardiotoxicity in guinea pigs were made by perfusing isolated heart with Langendorff appa- ratus. The free radicals generation in myocardium following the incidence of ventricular premative beat, ventricular tachycardia and ventricular fibrillation were measured respectively by the directed measurement with Electron Spin Resonance ( ESR ) techniques. The results showed the more severe toxicosis, the more much free radicals generate. Free radicals generated significantly in ventricular fibrillation and were scavenged by Superoxide dismutase ( SOD ) and sodium selenate.

Objective:To investigate the effect of oxycodone hydrochloride on patients with analgesic effect and immune function of intestinal tumor after operation.Methods:50 patients with intestinal tumor from June 2014 to December 2016 who were treated in our hospital were selected randomly to divide into oxycodone group and fentanyl group with 25 cases in each group.Patients in oxycodone group were given oxycodone hydrochloride intravenous injection of 5mg 15 minutes before the end of surgery;and patients in fentany group were given fentany intravenous injection of 50ug 15 minutes before the end of surgery.Visual analogue scale (VAS),ramsey sedation score were observed at 3 h (T0),6 h (T1),12 h (T2),24 h (T3) 48 h (T4) after operation,Levels of serum tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and IL-10 CD4+,CD8+,CD4+/CD8+ and NK cells measured before anesthesia,and at T2,T3,T4 respectively.Results:At time point of T1,T2,Ramsey scores of oxycodone group were significantly lower than that of fentany group (P＜0.05),At time point ofT0,T3,T4,Ramsey scores of the two groups showed no significant difference (P＞0.05).At time point of T2,T3,T4,levels of serum TNF-α,IL-6 and IL-10 of two groups of patients were significantly higher than those of anesthesia before (P＜0.05),TNF-α,IL-6 and IL-10 ofoxycodone group was significantly lower than those of fentany group (P＜0.05).At time point ofT2,T3,T4,CD4+/at CD4+ of the two groups were significantly decreased,and CD8+ was significantly increased(P＜0.05).Levels of CD4+,CD4+/CD8+ of oxycodone group was significantly higher than that of fentany group (P＜0.05),and level ofCD8+ was significantly higher than that of fentany group.At time point of T2,T3,NK cells of two groups were significantly decreased,NK cells of oxycodone group were significantly higher than that of oxycodone group (P＜0.05).Differences among postoperative nausea,vomiting,respiratory depression,dizziness,skin itching incidence of two groups of patients were not statistically significant (P＞0.05).Conclusion:Oxycodone hydrochloride has little effect on the immune function of patients with intestinal tumor,and it is suitable for Postoperative analgesia of patients with intestinal tumor.

ObjectlveTo evaluate the role of cannabinoid receptor 2 (CB2 receptor) in microglial injury induced by glutamate.MethodsMicroglia cells were randomly divided into 4 grups:control group (group C),microglial injury group ( group Ⅰ),specific CB2 receptor agonist AM 1241 group ( group AM1241 ) and specific CB2 receptor antagonist AM630 group (group AM630).In group C,the cells were cultured routinely for 26 h.In group Ⅰ,the cells were incubated in the culture medium containing glutamate 10 mmol/L for 24 h.In group AM1241,the cells were incubated in the culture medium containing AM1241 2 μmol/L for 2 h,and then in the culture medium containing glutamate 10 mmol/L for 24 h.In group AM630,the cells were incubated in the culture medium containing AM630 2 μmol/L for 2 h,and then in the culture medium containing glutamate 10 mmol/L for 24 h.The cell viability and release of LDH were measured.Microglial morphology was observed under microscope.Results Compared with group C,the cell viability was significantly decreased,and the release of LDH was significantly increased in groups Ⅰ,AM1241 and AM630 (P ＜ 0.05).Compared with group Ⅰ,the cell viability was significantly increased,and the release of LDH was significantly decreased in group AM1241 ( P ＜ 0.05).There was no significant difference in the cell viability and the release of LDH between groups 1 and AM630 ( P ＞ 0.05).Conclusion Glutamate induces microglial injury through inhibiting the function of CB2 receptor.
