Objective To observe the changes of intedeukin (IL)-17 in patients with maintenance hemodialysis (MHD) and its relationship with anemia. Methods Twenty sera from normal people(normal group) and sixty-eight sera from patients with MHD were sampled. Patients with MHD were divided into 4 groups by haemoglobin (Hb) levels: severity anemia group (12 cases), midrange anemia group(18 cases),light anemia group(18 cases) and non-anemia group(20 cases). IL-6 and IL-17 levels were measured in all the sera with ELISA. Meantime, C-reactive protein (CRP),Hb, ferritin and iron saturation ratio was observed. Results CRP,IL-17 and IL-6 levels in MHD patients were much higher than those in normal group. IL-17 levels in severity and midrange anemia group were higher than those in light anemia group,and IL-17 was positively correlated to Hb. Conclusions IL-17,IL-6 and CRP in patients is higher than that in normal people,and the microinflammation status exists in MHD. IL-17 may play a role in pathogenesis of microinflammation in MHD patients with anemia.

BACKGROUND: The morbidity of diabetes mellitus increased recently.There are few reports about the pulmonary function status of the patients with diabetes mellitus.OBJECTIVE: To comparably observe the difference of the pulmonary function status between patients with diabetes mellitus and normal persons,and to probe into the relationship between the course of disease of diabetes mellitus and the functional change of pulmonary function.DESIGN: Case controlled observation SETTING: Renmin Hospital, Wuhan University PARTICIPANTS: Totally 90 patients with diabetes mellitus hospitalized in the Renmin Hospital, Wuhan University between January 2000 and De cember 2003 were recruited. All the patients participated in the experiment voluntarily. Totally 20 cases were of insulin dependent diabetes mellitns (IDDM) and 70 cases were of non-insulin dependent diabetes mellitus (NIDDM). Another 90 cases were divided into 2 groups with the boundary line of 10 years: group with disease course ＜10 years (n=40) and group with disease course ＞10 years (n=50). And 30 normal persons with healthy pulmonary function was set as healthy control group, all the testees were voluntary participants in the experiment.METHODS: Pulmonary function index of the participants of each group was measured: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1%), peak expiratory flow rate(PEFR)maximal voluntary ventilation (MVV) and comparison was performed between them.Comparison of the pulmonary function status of the patients between different levels of diabetes mellitus.pulmonary function between different groups : Compared with health control group, VC , FVC and MVV of the patients with diabetes mellitus was significantly decreased (t=1.999-2.301, P ＜ 0.05).There was no significant difference in the VC, FVC and MVV between patients with monary function between patients with different diabetes mellitus: the pulmonary function status in the group with disease course ＞10 years was improved less than that in the group with disease course ＜10 years [ VC (L):2.62±0.65 vs 3.25±1.25;FVC(L): 2.40±0.52 vs 3.21±0.98;FEV1%:75.31±2.31 vs 80.63±5.56;PEFR (L/s):4.33±0.68 vs 5.98±1.02;MVV (L/s): 76.22±6.98 vs 89.21±5.69 (t=2.012-2.350, P ＜ 0.05)].CONCLUSION: Pulmonary function of the patients with diabetes mellitus has reduced tendency compared with the normal persons, and the pulmonary function of the patients with long course of disease decreases significantly. More attention should be paid to diabetes patients' pulmonary function changes.

Objective To investigate the prevalence of depression and its risk factors in type 2 diabetes mellitus.Methods Beck Depression Inventory (BDI) was used to evaluate depression in 2 966 type 2 diabetes mellitus patients [ male 1 463,female 1 503,age ( 56.4 ± 11.2 ) years,diabetes duration ( 6.3 ± 5.7 ) years ].Depression criteria:≤4 points,no depression group; 5-13 points,mild depression group; 14-20 points,moderate depression group; 21 points or higher,severe depression group.Meanwhile,the demographic and metabolic data and diabetes-related health behaviors were also investigated.The risk factors associated with depression were screened by logistic regression.Results 51％ patients had depression,including 38％ with mild,8％ with moderate,and 5％ with severe depression.Compared with no depression group,depression was correlated with female sex,low-annual income,diabetes education,diabetes treatment,with insulin and peripheral neuropathy( P＜0.01 ).More smoking and younger age were found in severe depression( P＜0.05 ).Partial correlation analysis showed that depression in type 2 diabetes mellitus was positively correlated with female sex,diabetes education,and peripheral neuropathy ; and negatively correlated with age (P＜0.05).Conditional logistic regression equation showed that gender( OR =1.37 ),age ( 20-40 years,OR =1.52 ),diabetes education ( OR =1.51 ),and peripheral neuropathy ( OR =1.87 ) were risk factors for depression.Conclusion Depression is common in type 2 diabetes mellitus.More attention should be paid to screening depression in clinical practice.

The effect of insulin treatment on fatty liver was investigated in diabetic mice fed with high-fat diet.C57 BL/6J mice were fed with high fat diet for 12 weeks,and then treated with Glargine for 4 weeks.The results showed that during intraperitoneal glucose tolerance test,blood glucose,serum total cholesterol and triglyceride(TG) were significantly lower in insulin-treated high fat group than those in untreated ones(P<0.05).The hepatic histology showed minimal or barely visible fat in hepmic cells along with TG content in liver decreasing by 20.71%. The results suggest that insulin ameliorates hepatic intracellular lipid accumulation induced by high fat diet.

To investigate the effect of compound Chinese traditional medicine PC-SPES II I in inhibiting proliferation of human prostate cancer cell LNCaP based on the androgen receptor (AR) signaling pathway. The effect of PC-SPES II on LNCaP cell proliferation was detected by MTT assay. According to the findings, at the mass concentration of 180-1 440 mg x L(-1), PC-SPES II significantly inhibited the proliferation of LNCaP cells; the IC50 of PC-SPES II at 24 h and 48 h were 311.48, 199.01 mg x L(-1), respectively. The flow Cytometry detection showed 240 mg x L(-1) PC-SPES II arrested cells in G2/M phase, and an obvious apoptotic peak appeared before G0/G1 peak and rose over time. Meanwhile, Hoechst 33258 staining revealed apoptotic cellular morphology. Annexin V-FITC/PI staining manifested an increase in apoptotic cell ratio at the PC-SPES II concentration of 480 mg x L(-1) in a dose dependent manner. The prostate specific antigen (PSA) secretion of LNCaP cells was tested by PSA ELISA kit. Besides, compared with 25 mg x L(-1) Bic, 480 mg x L(-1) PC-SPES II significantly reduced the cell secretion of PSA. The AR and PSA mRNA and protein expressions were detected by qRT-PCR and Western blot. According to the results, after the induction of LNCaP cells with synthetic androgen 25 μg x L(-1) R1881, 240-480 mg x L(-1) PC-SPES II notably down-regulated the AR and PSA mRNA and protein expressions and inhibited the translocation of AR from cytoplasm to nucleus. In summary, PC-SPES II significantly can inhibit the in vitro proliferation of LNCaP cells and arrest cell cycle arrest in G2/M phase. Its mechanism may be associated with the down-regulation of the AR and PSA expressions and the inhibition of AR nuclear translocation.

Objective To investigate the risk factors, clinical and angiographic features of women aged 50 or less with coronary artery disease(CAD). Methods One hundred and seventy-three female CAD patients comifrmed by coronary angiographic aged 50 or less were classiifed as group A, while another 494 non-CAD women aged 50 or less as group B. The differences in CAD risk factors, clinical and angiographic features between the 2 groups were analyzed. Results There were more women with diabetes, positive CAD family history, dyslipidemia or hypertension (especially diastolic hypertension) in group A than in group B. Patient in group A had higher diastolic pressures and serum glucose level than those in group B but both groups had similar body weights, systolic pressures and menopause ages. The serum total cholesterol and triglyceride levels were higher in patients in group A than those in group B while high-density-lipoprotein (HDL) cholesterol and apolipoprotein A levels were lower in group A. The low-density-lipoprotein (LDL) and apolipoprotein B were higher in group A than in group B but without signiifcance. There were more women with positive urine protein in group A than in group B. In group A, more than 50%of patients were with single diseased artery while another 15%with slight coronary artery atherosclerosis or even normal arteries. Most of the lesions were found in left anterior descending artery (LAD) and its branches. Conclusions Risk factors of CAD included diabetes, positive CAD family history, dyslipidemia, hypertension(especially diastolic hypertension) and positive urine protein in women aged 50 or less Menopause alone, without other CAD risk factors, would not lead to CAD. Single vessel disease was more commonly found in this group of patients.

Limit test of flavones in diterpene ginkgolides meglumine injection materials by UV-Vis and HPLC-DAD method was studied in this essay. The HPLC-DAD method has lower LOD (about 1% of the UV-Vis), that is, the sensitivity is higher than UV-Vis method. Through the analysis of the kinds of flavonoids ingredients in the samples by LC-MS, the three compounds with highest contents are kaempferol, quercetin and isorhamnetin. Kaempferol, quercetin and isorhamnetin were chosen as reference compounds for HPLC analysis, and the HPLC separation analysis was carried on an Agilent Eclipse plus C18 column (4.6 mm x 250 mm, 5 μm) with methanol and water containing 0.4% phosphoric acid (50: 50) as mobile phase, and the flow rate was 1.0 mL x min(-1). The detection wavelength was set at 360 nm. This method has good specificity, precision and reproducibility. The LODs of quercetin, kaempferide and isorhamnetin were 27.6, 22.3, 29.5 μg x L(-1). The average recovery was 87.9% (RSD 3.3%), 91.7% (RSD 3.1%), 88.3 (RSD 1.3%) for quercetin, kaempferide and isorhamnetin, respectively. Based on the 10 batches of sample results and sensitivity of different HPLC, the content of total flavonoids ingredients of diterpene ginkgolides meglumine injection materials was limited no more than 2 x 10(-5). This method is simple, quick and has good maneuverability, and could be used to the limit test of flavonoids in the diterpene ginkgolides meglumine injection materials.
