Objective To investigate the relationship between interleukin (IL)-17 and IL-10 in psoriasis.Methods The expression of IL-17 and IL-10 was measured by enzyme-linked immunosorbent assay in 32 patients with psoriasis (psoriasis group) and 30 normal controls (control group).The correlation of IL-17 and IL-10 was analyzed.Results The expression of IL-17 in psoriasis group was higher than that in control group[(57.59 ± 11.99) ng/L vs.(33.27 ± 6.49) ng/L] (t =9.84,P ＜ 0.01).The expression of IL-10 in psoriasis group was lower than that in control group [(25.38 ± 4.32) ng/L vs.(32.01 ± 5.54) ng/L] (t =5.27,P＜ 0.01).There was negative correlation between IL-17 and IL-10 in patients with psoriasis (r =-0.70,P ＜ 0.01).Conclusion The pathogenesis of psoriasis may be related to imbalance of IL-17 and IL-10.

Objective Using the stage management to evaluate the normalized pain management and to alleviate pain of primipara during delivery and improve comfort .Methods Sixty pregnant women were selected and were divided into the control group and the observation group , each with 30 cases.The control group was given the usual care during the first stage of delivery , while the observation group was given a set of normalized pain management and alternative experiences of intervention , therapeutic massage , meditation with music and birth ball.The numerical rating scale (NRS) and visual analog score (VAS) were used to assess the degree of pain, emotions and comfort feelings .Then, the degree of pain and changes of emotions and comfort were compared between groups .Results Within the observation group , 12 primipara ( 40.00%) had mild pain, 17 primipara (56.67%) had moderate pain, 1 primipara (3.33%) had severe pain.Within the control group, 5 primipara (16.67%) had mild pain, 21 primipara (70.00%) had moderate pain, 4 primipara (13.33%) had severe pain.There was a significant difference between groups (U =2.235, P =0.025).Within the observation group, 22 primipara (73.33%) had mild discomfort, 8 primipara (26.67%) had moderate discomfort.Within the control group, 10 primipara (33.33%) had mild discomfort, 17 primipara (56.67%) had moderate discomfort , 3 primipara ( 10 .00%) had severe discomfort .There was a significant difference between groups (U=3.222, P=0.001).There was no significant difference in the emotions between groups (U=0.800,P=0.424).Conclusions The stage management can significantly reduce the pain of primipara during delivery and improve their comfort .

Objective　To explore the possibility of telomerase as tumor marker of lung cancer and to evaluate its value on early diagnosis of lung cancer. Methods　Telomerase activity was measured in 40 resected specimens of lung cancer and 40 preoperative fibro-optic bronchoscope biopsied specimens of suspected lung cancer by PCR based silver staining telomeric repeat amplification protocal (TRAP) respectively. Results　The positive rate of telomerase was 100％ in SCLC, but 84.8％ in resected samples and 95.7％ in biopsied samples in NSCLC. The positive rate of telomerase was 87.5％(35／40) in resected lung cancer tissues, 7.5％(3／40) in paracancerous tissues and 0％(0／40) in normal lung tissues (P＜0.01). 82.5％ (34／40) biopsied specimens of suspected lung cancer were detected with telomerase activity. Its sensitivity, specificity， and accurate rate was 96.4％, 71.4％, and 91.4％ respectively for detection of lung cancer, Youden’s Index (J)＝0.678，and SE（J）＝0.174. Conclusion　Telomerase may be a sensitive tumor marker of lung cancer. Detecting telomerase activity in preoperative fibro-optic bronchoscope biopsied specimens may contribute to early diagnosis of lung cancer.

Objective:To analyze the changes in self-efficacy and its influencing factors in type 2 diabetic patients after community-based self-management group intervention.Methods:From August to November 2014, a 3-month community-based self-management intervention study of type 2 diabetes patients was implemented in Fangshan District, Beijing. 510 patients were recruited through posters, household inquiries and telephone notification and then were randomly divided into intervention group (260 patients) and control group (250 patients). Finally, 500 patients completed the study, including 259 in the intervention group and 241 in the control group. Self-efficacy score was measured through face-to-face interview at different time points, including pre-intervention, post-intervention, 2 years after the intervention and 5 years after the intervention, respectively. A two-level random coefficient model was fitted to analyze the long-term trend of self-efficacy and its relationship with group intervention.Results:Individual-level educational attainment, disease duration as well as their treatment plans had a positive correlation with self-efficacy of type 2 diabetic patients while gender and age did not affect their self-efficacy. Patients with junior middle school education, senior high school education and university and above education had 4.66 ( P<0.05), 6.40 ( P<0.05) and 11.02 ( P<0.05) points higher than those with primary education, respectively. The self-efficacy of diabetic patients increased by 0.23 ( P<0.05) for each additional course year. The effect of treatment plan on self-efficacy was mainly reflected in the self-efficacy of taking medication or insulin injection as prescribed and blood glucose monitoring. After controlling for the confounding factors, i.e., gender, age, disease duration, educational attainment, and treatment plan, self-efficacy scores at the post-intervention increased in both groups compared to those at the pre-intervention. The intervention group had 7.95 points higher than the control group ( P<0.05). After the intervention, the self-efficacy scores of both groups decreased year by year while the intervention group declined faster, with 5.41 points ( P<0.05) at 2 years after the intervention and 8.94 points ( P<0.05) at 5 years after the intervention. Conclusion:Community-based self-management group intervention could improve the self-efficacy of type 2 diabetic patients while the self-efficacy decreases year by year in the absence of follow-up intervention.
