Objective To investigate the role of depression and C-reaction protein (CRP)in the early development of vascular disease in the elderly patients with type 2 diabetes. Methods Totally 396 patients with type 2 diabetes were recruited in the study,including 196 cases with depression and 200 cases without depression.Depression was evaluated by Hamilton depression scale (HAMD),and CRP was measured using rate nephelometry.The related parameters of wave intensity (WI) such as accelerating wave intensity (W1),decelerating wave intensity (W2),arterial stiffness β,pressure-strain elasticity modulus (Ep),arterial compliance (AC),pulse wave velocity -wave intensity(PWVWI),pulse wave velocity (PWV) and argumentation index (AI) were detected and compared between the groups. Results The levels of CRP [(8.1±2.8)mg/L vs. (3.9±3.2) mg/L,t=6.411,P=0.000],W2 [(4.82±1.33) mm Hg· m-1 · s-3 vs.(2.27±1.28)mm Hg · m-1 · s-3,t=4.256,P=0.021],arterial stiffness β(12.58±3.23 vs.8.96±2.24,t=4.634,P=0.019),Ep (157.90±52.64 vs.118.24±53.08,t=5.512,P=0.007),PWVβ(7.53± 1.41 vs.6.68±1.56,t=3.982,P=0.024),AI(19.26± 13.21 vs.15.34±10.23,t=3.213,P=0.037)and PWV-WI (7.59±1.67vs.6.63± 1.45,t =2.613,P =0.046) in cases with depression were higher than the cases without depression,while the AC value was reduced (0.70±0.19 vs.0.78±0.21,t=4.676,P =0.017).There was no difference in W1 value between the groups.The CRP level and HAMD score were positively associated with W2 (r=0.470,P=0.000),stiffness β (r=0.582,P=0.000),Ep (r=0.352,P=0.004),PWV-WI (r=0.233,P=0.019),PWVβ (r=0.340,P=0.007) and AI (r=0.265,P=0.015),but negatively related with AC(r=-0.457,P=0.000).HAMD score was positively correlated with CRP level(r=0.328,P=0.003). Conclusions The carotid artery wave intensity W2,blood vessel elasticity parameter β,Ep,AC,PWV-WI,PWVβ and AI determination can evaluate the risk of cardiovascular diseases in elderly diabetes,and higher CRP level and HAMD score may deteriorate its process.

Red blood cell sorbitol contents were determined with a enzymatic method in 37 diabetics and 19 controls. The fasting blood glucose (FBG) levels and RBC sorbitol contents in the diabetics were significantly higher than that in the controls. RBC sorbitol was positively correlated to FBG, but not to the age of the patients or the type and duration of diabetes mellitus. In 9 patients whose nerve conduction velocity was measured, RBG sorbitol content was negatively correlated with motor nerve conduction velocity of median nerve (r =-0.768, P

Objective To detect the micro satellite instability (MSI) from the precancerous and cancerous lesions (GC) and its effect on carcinogenesis.Methods Silver staining single strand conformation polymorphism polymerize chain reaction (PCR SSCP) was used to screen MSI markers at 5 loci in formalin fixed,paraffin embedded tissues of GC (n=30), dysplasia (n=30), intestinal metaplasia (IM) ( n =40) and corresponding normal gastric tissues.Results The abnormal shifting of the single strand DNA was identified in 7(23 3%)out of GC, in 9 (30%) out of dysplasia and in 8(20%) out of IM samples respectively. GC with MSI was associated with distal location of the tumors ( P =0 044). MSI was not detected in low grade IM tissues.Conclusion MSI may be of an early event during gastric carcinogenesis. It contributes probably to the acquisition of a transformed cell phenotype and to the development of gastric cancer.

Objective To observe the effect of short-term treatment with metfbrmin on psychological distress and metabolic feature in patients with polycystic ovary syndrome(PCOS).Methods Ninety women were diagnosed as cases of PCOS based on the 2003 Rotterdam criteria.These patients were divided into three groups:group A,consisted of 26 subjects treated with mefformin only; group B,36 cases treated with metformin plus Dane-35 ; and group C,28 cases treated with placebo and Dane-35.The treatment was carried out for 3 months.Clinical and metabolic parameters were observed.The psychological distress was evaluated by the hospital anxiety and depression scale(HAD scale).Results Compared with group C,patients in group A and B showed significantly lower body mass index(BMI),waist circumference (WC),waist-hip ratio (WHR),serum fasting insulin,homeostasis model assessment for insulin resistance (HOMA-IR),total cholesterol (TC),triglyceride (TG),low density lipoproteincholesterol(LDL-C) levels as well as anxiety and depression scores,but higher high density lipoprotein-cholesterol (HDL-C) levels (all P＜0.05).Compared with group A,patients in Group B had significantly higher WC,WHR,and LDL-C levels(all P＜O.05).No significant differences in BMI,TG,HDL-C,anxiety and depression scores were found between group A and B (all P＞0.05).In group A,a positive correlation was found between the changes of metabolic feature (BMI,WHR,and HOMA-IR) and the changes of anxiety and depression scores (all P ＜0.05).Conclusion Short-term treatment with metformin will benefit patients with polycystic ovary syndrome,regarding psychological distress and metabolic features.

Objective To discuss the treatment of dopamine extravasation-induced injury by lidocaine combining dexamethasone. Methods Animal models of dopamine extravasation-induced injury were made using 24 limbs of 6 white mice. These models were divided into 4 groups and given different treatments. Group A was treated with lidocaine combining dexamethasone, group B with lidocaine, group C with normal saline and group D was set as control. The treatment effect was observed.

Objectives To investigate the activities of daily living and analysis of the influencing factors among elder hospitalization patients.Methods A series of scales including Activity of Daily Living Scale,Mini-Nutritional Assessment,Mini Mental State Examination,Geriatric Depression Scale 15,Falls Risk Assessment Tool and Euro Qol-5D Questionnaire were used to assess the physical and psychological health status among elder patients at first hospitalization,as well as their social-economic status,and to analyze the activities of daily living and influencing factors.Results Interviewees with less than nine years educational level had 5.93 (95 ％ CI:1.14-33.23)times higher risk for impaired activities of daily living than those with higher education levels.Patients with EQ-5D score ≥1 scale or with cognitive disorder showed 2.86 (95％ CI:1.04-8.05) times or 18.14 (95 ％ CI:1.64-540.63) times higher risks for impaired activities of daily living than their normal controls,respectively.The risks for the decreasing activities of daily living were increased along with ageing (P =0.025).There was a marginal correlation between regular exercise and activities of daily living(P=0.104).Conclusions Educational level,health status and cognitive function are important factors for activities of daily living among elder hospitalization cases and enlarged sample size is required for validation.

BACKGROUND:Sodium butyrate, a histone deacetylase inhibitor, can inhibit cell proliferation, and induce apoptosis and differentiation of various cancer cells. However, the role of sodium butyrate combined with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on lung cancer stem cells remains unclear. OBJECTIVE:To explore the effect of sodium butyrate combined with TRAIL on biological behaviors of lung cancer stem cells. METHODS:Magnetic bead separation was used to separate lung cancer stem cells (CD133+) from human lung adenocarcinoma A549 cells. After the lung cancer stem cells were treated with simple DMEM/F12, DMEM/F12 containing sodium butyrate (5 mmol/L), TRAIL (50 μg/L) or sodium butyrate combined with TRAIL, the cell proliferation within 96 hours of culture was determined by MTT assay; the apoptosis within 24 hours of culture was measured by flow cytometry; the cell migration within 48 hours of culture was detected by cell scratch test; the expression levels of pluripotent transcription factors (Oct4, Sox2 and Nanog) within 48 hours of culture were detected using western blot analysis. RESULTS AND CONCLUSION:The CD133+ lung cancer stem cells were successfully enriched from human lung adenocarcinoma A549 cells. MTT assay showed that sodium butyrate and TRAIL significantly inhibited the proliferation of lung cancer stem cells (P< 0.05), and the combination effect was even stronger (P < 0.05). Results from flow cytometry analysis and scratch test showed that sodium butyrate or TRAIL induced apoptosis and inhibited cell migration of lung cancer stem cells (P < 0.05), and the combination of sodium butyrate and TRAIL showed a stronger effect (P < 0.05). In addition, the expression levels of Oct4, Sox2 and Nanog were significantly down-regulated by sodium butyrate (P < 0.05), TRAIL or sodium butyrate combined with TRAIL, and the combination effect was stronger (P < 0.05). In conclusion, sodium butyrate and TRAIL have synergistic effects on lung cancer stem cells, indicating a new way for treatment of lung cancer.
