Objective To observe the dynamic levels of IL-2,IL-5 and IL-6 produced by Balb/ c mice infected with DEN_2 clinical strains and to study their relation.Methods The Balb/c mouse in- feetion model was established by multiple-site subcutaneous injection with various doses of DEN_2 clini- cal strain.Mouse plasma samples collected from different experiment groups at various time after in fection were tested for IL-2,IL-5 and IL-6 levels with sandwich ELISA.Results After primary in- feeted with DEN_2 B strain,the levels of IL-2,IL-5 and IL-6 of all experimental groups were not sig- nificantly higher than the normal control group while the levels of experimental groups increased sig- nificantly after re-infection.The level of IL-2 reached to peak[average value of(101 522.44?10 465.375)pg/ml]at the 4th day after re-infection(the 20th day after the primary infection),and then the level gradually reduced.The levels of IL-5 in the Balb/c mice of the group 1 and 2 reached to peak at the 1st day after re infection(the 16th day after the primary infection),and there was signifi- cant difference between these two groups and the control group(P＜0.05).The levels of IL-6 in all experimental groups reached to peak at the 1st and the 2nd day after re-infection.The peak value of the third group is the highest comparing with the normal control group(P＜0.05).Conclusion Th2 response was predominant in the second infection phase.

Objective To evaluate the efficacy and toxicity of weekly docetaxel and cisplatin in previously untreated patients with advanced non-small-cell lung carcinoma. Methods Between January 2002 and December 2003 ,34 patients with pathologically comfirmed advanced non-small-cell lung carcinoma who had not received treatment were enrolled. The mean age was under 66 years. The patients received intravenous infusions of docetaxel(25 mg/m2,dayl ,8,15) with dexamethasone premedication and cisplatin(25 mg/m2,dayl ,8,15) ,followed by a week of rest. The remedies which were less than 6 regimens lasted to disease progression or severe toxicity. Therapeutic effect was evaluated by CT scan every two courses . The patients were followed up for 24 months. Descriptive statistics and SPSSIO. 0 software were used to analyse the results. Results 34 patients finished 90 courses. The mean was 2. 6 courses. All patients were followed up. Two patients achieved complete responses, ten patients achieved partial responses, ten patients achieved stable disease. An objective response rate of 35. 29% (95% confidence interval 19. 25%-51. 33% )was obtained. Patients life quality was significantly improved. The median time to progression was 4. 1 months, and median overall survival was 11 months. The 1-year survival rate was 47. 06% , the 2-year survival rate was 11.76% . Toxicities were mild. Grade 3 to 4 neutropenia (11.76%), anemia (5.88%), hyponatremia (5.88%), alopecie (17.64%) and nausea/vomiting (5. 88% ) were observed. Conclusion Weekly Cisplatin plus docetaxel is an effective and well-tolerated regimen in chemo-naive patients with advanced NSCLC. Well-designed clinical trials should be conducted.

objective To explore the role of cytokines and dendritic cells (DCs) in rat high-risk corneal allograft survival pro- longed by superantigen Staphylococcal Enterotoxin B (SEB) and to compare the different effects between SEB and glucocorticoid. Design Experimental study.Participants Fisher 344 and Lewis rats.Methods The Fisher 344 and Lewis inbred rats were used for high-risk penetrating keratoplasty model.All of the Lewis rat recipients were divided into three groups by blinded fashion.GroupⅠand GroupⅡrats were injected intraperitoneally with 0.2ml saline buffer or SEB (75?g/ml) respectively at 4-day intervals on three occasions before transplantation.GroupⅢrats were injected subconjunctivally with 0.1ml dexamethasone (1mg/ml) daily from the first day after surgery for 2 weeks.The allograft survival was examined under slit-lamp.The concentration of interleukin IL-1?,IL-2,IL-4,IL-5,IL-6, IL-10,TNF-?in rat aqueous humor and peripheral blood were measured by liquichip and the cytokine and CD11c,CD80,MHC-Ⅱex- pression in corneal grafts were examined by immunohistochemestry staining.Main Octcome Measures Mean survival time of the allo- grafts,the level of cytokines in aqueous humor,peripheral blood and corneal grafts.Results Compared with group control,the grafts mean survival time was delayed about 3.8d in group SEB (P=0.00) and 7.1d in group dexamethasone(P=0.01).But there was no signifi- cant difference between group SEB and dexamethone (P=0.26).Liquichip test showed that the level of IL-1?in aqueous humor was re- duced and IL-4,IL-6 and IFN-?,ascended.Only IFN-?,and IL-6 could be found in peripheral blood,and the changing shift of them was similar to that in aqueous humor.The immunohistochemistry staining showed that the expression of IL-2 in rat corneal grafts was signif- icantly decreased but IL-4,IL-6 and IL-10 elevated.The expression of DCs in group SEB was similar to that in group control,which was elevated after keratoplasty,but the phenotype of DCs was not the same.There were predominantly mature DCs in group control while immature DCs in group SEB.Conclusions The immunological inhibiting effect of SEB is same to glucocorticoid,but the mecha- nism is different.SEB can modulate immune response,which might induce immune inhibition via the local production of cytokines and effect on DCs maturation involving corneal graft rejection prevention.

Objective To explore the association between sleep quality and the increasing risk of type 2 diabetes mellitus (T2DM).Methods A total of 771 patients aged 25-70 years living in Xuzhou City of Jiangsu Province for at least 5 years were enrolled for the survey of risk factor related noninfectious chronic disease in 2013.In this investigation,those who suffered from other types of diabetes,neuropathy,other endocrine disease,cardiovascular,renal and hepatic dysfunction,dyspnea or cancer were excluded.To reduce the influence of confounding factors,another 771 participants were enrolled as controls.Each case was arranged to have a control who was matched in age (difference not more than 3 years),gender,residence and family history.All the participants were interviewed with self-designed questionnaire,and sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI) questionnaire.Student's t test,Chi-square and multivariate logistic regression were used for data analysis.Results The PSQI score in the T2DM patients vs.the controls were 5.15±2.40 vs.2.71 ± 1.93 (t=21.96,P＜0.01).The scores of sleep-related factors,including subjective poor sleep quality,bedtime resistance,short sleep duration,sleep efficiency,sleep disturbance,use of sleep medication and daytime dysfunction,of the T2DM patients were higher than those of the controls.The proportion of sleep related behaviors of the T2DM patients was higher,except for early awakening,cold feeling and nightmare.Poor sleep quality was associated with the increasing risk of T2DM (odds ratio 2.06,95％ CI 1.69-2.52).In multivariate logistic regression,when adjusted for confounding factors,the risk of T2DM was still increased (odds ratio 1.72,95％ CI 1.62-1.83).Sleep-related factors (e.g.subjective poor sleep quality,bedtime resistance,short sleep duration,sleep efficiency and sleep disturbance) were correlated with the risk of T2DM (odds ratio was 3.34,1.63,1.10,1.87 and 3.89,respectively).Conclusion Low quality of sleep may be strongly associated with an increased risk of T2DM.

Objective:To explore the effect of cognitive-behavioral therapy on psychological stress and quality of life in patients with pulmonary tuberculosis.Methods:According to two-level cluster random design 461 patients with tuberculosis from 20 communities in Pizhou county of Jiangsu province were selected in the study from September 2018 to November 2018. The intervention group received cognitive-behavioral therapy for two months, while control group received routine follow-up. Anxiety, depression and quality of life were assessed by GAD-7, PHQ-9 and SF-36 scales, respectively. At the same time, the comparison between the two groups was conducted by independent sample t test, and the difference between the two groups before and after treatment was analyzed by paired sample ttest. Results:A total of 454 participants were finally included in this analysis; there were 230 cases in the intervention group and 224 cases in the control group. In the intervention group the scores of anxiety and depression after intervention were significantly lower than the baseline scores [(7.57±5.27) vs. (5.93±2.56), t=-4.245, P<0.01; (8.13±6.01) vs. (6.02±2.67); t=-4.866, P<0.01], and the quality of life score was significantly higher than the baseline score [(58.46±12.71) vs. (74.31±13.22); t=13.108, P<0.01]; while in the control group there were no significant differences in the scores of anxiety, depression and quality of life after intervention, compared with those at baseline [(7.62±5.41) vs.(7.65±5.38); (8.00±5.84) vs. (8.07±5.91); (59.11±13.25) vs. (60.51±13.76); t=0.059, t=0.126, t=1.104, all P>0.05]. However, only for patients with mild and moderate anxiety and depression symptoms in the intervention group, the anxiety and depression scores were decreased after intervention [(7.29±1.21) vs. (5.54±1.71), (11.99±1.31) vs. (9.17±1.55); (7.01±1.47) vs. (4.42±1.22), (11.88±1.12) vs. (8.39±2.33); t=8.056, t=10.020, t=13.558, t=8.852,all P<0.01]. Conclusion:Cognitive-behavioral therapy can relieve the psychological pressure and improve the quality of life in pulmonary tuberculosis patients with mild or moderate anxiety/depression symptoms.

OBJECTIVETo investigate the influence of total flavonoids of epimedium (TFE) on the streptozocin (STZ)-induced kidney injury in diabetic rats and discuss the possible mechanism.

METHODSDiabetes was produced by a single injection of streptozocin (40 mg/kg, iv) in male SD rats. The rats were randomly divided into three groups (n = 10): control group, model group and TFE group (100 mg/kg, ig). Animals were sacrificed 12 weeks later. The level of blood glucose, blood urea nitrogen (BUN) and creatinine (Cr) as well as the renal index were determined. Detect the specific biochemical of renal tissue: superoxide dismutase (SOD), malondialdehyde (MDA). Use masson staining to observe the morphology of the renal tissue. Immunohistochemistry was employed to determine the protein levels of transforming growth factor-beta1 (TGF-beta1).

RESULTSCompared to control group, the enhancement of blood glucose, renal index, BUN and Cr was found in model group, which was significantly attenuated by treatment with TFE. Meanwhile, elevated MDA level in renal tissue as well as decreased SOD activities in renal tissue were significantly remitted by TFE. Furthermore, TFE decreased the expression of TGF-beta1.

CONCLUSIONTFE can evidently relieve renal damage in rats with diabetic nephropathy induced by STZ, which might be related to antioxidation and modulating the expression of TGF-beta1 protein.
