OBJECTIVE To investigate the anti-inflammatory mechanisms of demethylzeylasteral(Dem)in ulcerative colitis(UC)and collagen-induced arthritis(CIA),focusing on its regulation of Th17 cell differentiation and associated signaling pathways.METHODS UC was induced in C57BL/6 mice using dextran sulfate sodium(DSS),and Dem was administered by gavage at low(1 mg·kg-1)or high(2 mg·kg-1)doses.Disease severity was assessed by body weight loss,colon length,and stool consisten-cy.Serum cytokines(TNF-α,IL-1β,IL-6)were quantified by ELISA,and Th17 cell ratio in mesenteric lymph nodes was deter-mined by flow cytometry.The anti-inflammatory efficacy of Dem was further validated using a CIA mouse model.The efficacy of Dem was further verified in the CIA model,and the expression of JAK2 and STAT3 was intervened by siRNA to investigate its mechanism of action in Th17 differentiation.RESULTS Dem-treated mice showed reduced weight loss and colon shortening,and decreases in ser-um TNF-α,IL-1β,and IL-6 levels(P<0.01)and Th17 cell proportion(P<0.01).Western blot and siRNA assays showed that Dem significantly inhibited the differentiation and activation of Th17 cells by suppressing the phosphorylation of the JAK2-STAT3 path-way.Dem also significantly alleviated arthritis symptoms and related markers in the CIA model,confirming its anti-inflammatory effects.CONCLUSION Dem improves UC and rheumatoid arthritis by downregulating the JAK2-STAT3 signaling pathway,inhibi-ting Th17 cell differentiation and pro-inflammatory cytokine expression,suggesting its potential therapeutic value in immune-related diseases.

Objective To evaluate the macular visual function of patients with myopic choroidal neovascularization (MCNV) before and after intravitreal injection of conbercept.Methods A prospective,uncontrolled and non-randomized study.From April 2017 to April 2018,21 eyes of 21 patients diagnosed as MCNV in Shanxi Eye Hospital and treated with intravitreal injection of conbercept were included in this study.There were 9 males (9 eyes,42.86％) and 12 females (12 eyes,57.14％),with the mean age of 35.1 ± 13.2 years.The mean diopter was-11.30 ± 2.35 D and the mean axial length was 28.93 ± 5.68 mm.All patients were treated with intravitreal injection of conbercept 0.05 ml (1+PRN).Regular follow-up was performed before and after treatment,and BCVA and MAIA micro-field examination were performed at each follow-up.BCVA,macular integrity index (MI),mean sensitivity (MS) and fixation status changes before and after treatment were comparatively analyzed.The fixation status was divided into three types:stable fixation,relatively unstable fixation,and unstable fixation.The paired-sample t-test was used to compare BCVA,MI and MS before and after treatment.The x2 test was used to compare the fixation status before and after treatment.Results During the observation period,the average number of injections was 3.5.The logMAR BCVA of the eyes before treatment and at 1,3,and 6 months after treatment were 0.87±0.32,0.68±0.23,0.52±0.17,and 0.61 ±0.57,respectively;MI were 89.38 ± 21.34,88.87 ± 17.91,70.59 ± 30.02,and 86.76 ± 15.09,respectively;MS were 15.32 ± 7.19,21.35 ± 8.89,23.98 ± 11.12,22.32 ± 9.04 dB,respectively.Compared with before treatment,BCVA (t=15.32,18.65,17.38;P＜0.01) and MS (t=4.08,3.50,4.26;P＜0.01) were significantly increased in the eyes 1,3,and 6 months after treatment.There was no significant difference in the MI of the eyes before treatment and at 1,3,and 6 months after treatment (t=0.60,2.42,2.58;P＞0.05).Before treatment and at 1,3,and 6 months after treatment,the proportion of stable fixation were 28.57％,38.10％,38.10％,33.33％;the proportion of relatively unstable fixation were 47.62％,47.62％,52.38％,57.14％ and the proportion of unstable fixation were 23.81％,14.28％,9.52％,9.52％,respectively.The proportion of stable fixation and relatively unstable fixation at 1,3 and 6 months after treatment were higher than that before treatment,but the difference was not statistically significant (x2=1.82,1.24,1.69;P＞0.05).Conclusion BCVA and MS are significantly increased in patients with MCNV after intravitreal injection of conbercept.

Objective · To evaluate the value of ultrasonic measurement of distance from skin to epiglottis (DSE) for predicting the difficult airway. Methods · 71 patients (20-80 year-old, ASA Ⅰ-Ⅲ ) undergoing endotracheal intubation and general anesthesia for an elective surgical procedure were enrolled. Conventional airway evaluation was performed. The distance from skin at thyroid cartilage upper edge to epiglottis was measured using ultrasound before anesthesia and compared between patients with difficult airway and normal airway. The effects of different methods for evaluating difficult airway were analyzed Results · The ultrasonic measurements of DSE on parasagittal view in patients with difficult airway and normal airway were (23.31±0.43) mm and (19.21±0.27) mm, respectively. The difference was statistically significant (P=0.003). The area under the ROC curve of ultrasonic measurement was 0.799 (95% CI:0.639-0.958) with the best cutoff point of 23.6 mm. The specificity of ultrasonic measurement was significantly increased as compared with Mallampati classification (96.43% vs 71.40%, P=0.004). The difference in sensitivity was not statistically significant (60.00% vs 73.33%, P=0.170). Conclusion · Ultrasonic measurement of DSE on parasagittal view can be used to predict the difficult airway.

Objective: To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m², 10 mg/m² or 12 mg/m² as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) . Methods: A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m²) as induction chemotherapy in newly diagnosed patients of adult AML. Results: Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (P<0.001) . After adjusted for age, blast ratio of bone marrow, FAB classification and risk stratification, the odds ratios (95% CI) of IDA 10 mg/m² group and IDA 12 mg/m² group were 0.49 (0.34-0.70) and 0.36 (0.18-0.71) , as compared with the IDA 8 mg/m² group (P<0.001, P=0.003) . In the intermediate and favorable groups, CR rates was 76.5% (163/213) , 86.9% (506/582) and 86.1% (68/79) in different doses of IDA (P=0.007) . Interestingly, IA regimen with IDA 10 mg/m² was the only beneficial factor affecting CR in this group after adjusted for age, blast ratio of bone marrow and FAB classification[OR=0.47 (95% CI 0.31-0.71) , P<0.001]. CR rates in adverse group was 50.0% (18/36) , 60.6% (43/71) and 81.8% (18/22) respectively (P=0.089) . However, the odds ratios (95% CI) of IDA 12 mg/m² when compared with the IDA 8 mg/m² was 0.22 (0.06-0.80) , after adjusted for age, blast ratio of bone marrow and FAB classification. The median time (days) of neutrophil count less than 0.5×10⁹/L in IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 14 (11-18) , 15 (11-20) and 18 (14-22) , respectively (P=0.012) and of platelet count lower than 20×10⁹/L were 14 (7-17) , 15 (11-20) and 17 (15-21) , respectively (P=0.001) . The incidences of lung infection in the three groups were 9.8%, 13.5% and 25.2%, respectively (P<0.001) . Conclusions For young adult patients (aged 18-60 years) with AML in China, intensifying induction therapy with idarubicin 10 mg/m² is clinically superior to IDA 8 mg/m² and IDA 12 mg/m² in favorable intermediate AML subgroup. However, idarubicin 12 mg/m² is more suitable to adverse AML subgroup.

Objective To establish a Chinese hamster model of babesia infection, to find the changing pattern of organs and biochemical parameters in Chinese hamster infected with Babesia, and to promote the detection and treatment of babesiosis.Methods Healthy 5-week old Chinese hamsters were infected by intraperitoneal injection of blood containing Babesia.Blood samples were collected at 0, 2, 4, 6, 8, 10, 12, 14, 16, 23, 30, and 37 days after infection from 5 hamsters at each time point.Blood smears were prepared to detect the parasites using Giemsa staining.ELISA assay was employed to test the IL-2 concentration.The blood biochemical indexes were detected using an automatic biochemical analyzer.DNA was extracted from the whole blood and REAL-TIME RCR was performed to determine the reproduction of Babesia.Aftert the animals were sacrificed, the heart, lung, spleen, liver, and kidney were taken to analyze the changes of organ coefficients.Results The highest level of Babesia in the hamsters occurred on day 4 after the Babesia injection, and then showing a decreasing tendency.However, there was a transient increase on the 12th day after infection.The liver and spleen displayed most extensive response to the infection showing hepatomegaly and splenomegaly, but the variation of heart and kidneys coefficients was within the norm.There were prominent changes of blood cells, especially leucocytes, with two peaks at day 10 and 23 after the Babesia infection.The peak changes of blood biochemical indexes occurred at day 12 after infection.The concentration of serum IL-2 reached a peak on the 10th day after infection.Conclusions The Chinese hamsters display typical characteristics of tick-borne diseases such as hepatomegaly and splenomegaly.The immunological system is activated along with the infection and reaches a highest stage in the second week.Afterwards the Babesia can live in the hamster body for a long period of time.The results of this study provide useful information supporting further studies on the detection, treatment and prevention of Babesiosis.

Objective To compare the effects of equivalent dose sufentanil,remifentanil or fentanyl on hemodynamic and cardiac output in the elderly patients during induction of general anesthesia.Methods Ninety elderly patients(ASA Ⅰ ～ Ⅱ) undergoing elective abdominal surgery under general anesthesia were randomly divided into sufentanil group(group S),remifentanil group(group R) and fentanyl group(group F),30 patients in each group.Patients in group S,group R and group F received sufentanil 0.2μg/kg,remifentanil 2μg/kg and fentanyl 2μg/kg Ⅳ,respectively,using an blind method before intubation.SBP,DBP,MAP,HR,CO,CI and SVR were recorded before of anesthesia (T0),immediately after induction (T1),1,3 minutes after tracheal intubation (T2,T3).Changes of SBP and HR during observation were also recorded.Results The MAP and HR in three groups at T1 were significantly lower than those at T0 and decreased significantly in group R than those in group F and S(P ＜0.05).The MAP and HR in group F significantly increased at T1 than T0.The MAP and HR in group R were significantly decreased after tracheal intubation.Compared with the baseline,the MAP and HR in group S at T1,T2,remained unchanged.In group R,there were two patients whose HR were under 50 bpm.In group F,the MAP at T1,T2 were significantly higher than those at T.In group S,there were no significant changes in CO,CI,SVR which were all within normal range (P ＞ 0.05).Conclusion Both sufentanil and remifentanil effectively inhibit the stress response during induction of general anesthesia.At the same time,sufentanil has better hemodynamic stability.

Objective To investigate the incidence and the risk factors of anxiety or depression and in the first degree relatives (FDRs) of patients with type 2 diabetes mellitus ( T2DM ). Methods A total of 102 T2DM patients who visited our hospital from May to July 2010 and their FDRs completed SAS,SDS,and life satisfaction evaluation. The medical history of T2DM patients was collected and compared with their FDRs with or without mental disorders. The correlations of risk factors with anxiety or depression were analyzed, t test or X2 test were used for statistical analysis and a P value less than 0. 05 was considered statistically significant. Results The incidence of anxiety or depression of FDRs was 31.4% and 17.6%,respectively. The life satisfaction score of FDRs with mental disorders was significantly decreased ( t = 4. 26 and 4. 09, P＜0. 05 ). Fasting glucose level of T2DM patients with anxious or depressive FDRs was significantly increased ( t = -2. 48 and -2. 15, P＜0. 05 ). Higher medical cost and multiple treatment strategies were positively correlated with SAS and SDS score of the FDRs. Conclusion Higher incidence of mental disorders and lower satisfaction scores could be found in the FDRs of T2DM patients. Better control of blood glucose and reduced treatment cost and strategies may be useful in improving metal condition and life satisfaction of the FDRs of T2DM patients.
