Objective:This work aims to detect the levels of miR-200c/141 methylation and miR-200c/141 in gastric cancer tissue and investigate the relationship between miR-200c/141 expression and clinical parameters. Methods:The methylation status of miR-200c/141 CpG island and miR-200c/141 in gastric cancer tissue specimens was evaluated by qRT-PCR or BS-MSP method. We analyzed the relationship among the methylation status of miR-200c/141 CpG island, expression level of miR-200c or miR-141, and clinical parame-ters. Results:The status of miR-200c/141 CpG island methylation in gastric cancer tissue was significantly higher compared with that in paracarcinoma tissue. MiR-200c and miR-141 were markedly decreased in gastric cancer tissue compared with those in adjacent tis-sue. MiR-200c/141 CpG island methylation was negatively related with the expression of miR-200c and miR-141 in gastric cancer speci-mens. Conclusion:The upregulation of miR-200c/141 CpG methylation inhibits miR-200c/141 expression in gastric cancer tissue.

OBJECTIVE:To investigate the effects of leukotriene receptor antagonist montelukast on inflammatory factor,air-way anatomy and lung function of children with cough variant asthma. METHODS:A total of 86 children with cough variant asth-ma selected from our hospital during Apr. 2010 to Aug. 2015 were divided into control group and observation group according to random number table,with 43 cases in each group. Control group was given Budesonide aerosol 0.4 mg,bid;observation group was given Montelukast sodium chewable tablets with different dose according to age(4 mg for 2-6 year-old,tid;5 mg for 7-12 year-old,tid).A treatment course of 2 groups lasted for 4 weeks,and both groups received 2 courses of treatment. The levels of inflammatory factor,airway anatomy and lung function indexes were detected in 2 groups before and after treatment,and the oc-currence of ADR was also observed. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05). Compared to before treatment,the levels of IL-4,IL-6,IL-8,TNF-α and hs-CRP in 2 groups were de-creased significantly after treatment;airway wall thickness,basement membrane thickness,airway wall thickness/outside diameter ratio,total area of airway wall,total area of airway wall/total area of airway were decreased significantly,while FVC,FEV1, FEV1/FVC,PEF were increased significantly;the indexes in observation group were significantly better than control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:For pediatric cough variant asthma,montelukast can significantly improve inflammatory reaction,airway status and lung function with good safety.

ObjectiveTo evaluate the adverse events occurred during tumour necrosis factor (TNF)-αblocker treatment in Chinese Han population patients with ankylosing spondylitis (AS).MethodsThis study had enrolled 369 Chinese Han population patients with ankylosing spondylitis.They all received TNF-αblocker treatment in the hospital.All 1011 administration were recorded in total.All of them were evaluated for adverse events 2 hours after injection,126 of them had received long-term TNF-α blocker injection,and they were followed-up at week 8,12,52,104.Mild immediate adverse events and long-term adverse events were all counted.SPSS 10.0 software package was used for Fisher's exact test.ResultsThree hundred and sixty-nine patients had 1011 administrations in total,652 had received rhTNFR:Fc,316 had infliximab,21had etanercept,22 had adalimumab injections.Adverse events 2 hours after injection were:17 (2.6％) for rhTNFR:Fc,12 (3.8％) for infliximab,0 for etanercept,1 (4.5％) for adalimumab.Twenty adverse events were mild(12 for rhTNFR:Fc,9 for infliximab),5 events were moderate(3 for rhTNFR:Fc,1 for infliximab,1 for adalimumab),4 events were severe(2 for rhTNFR:Fc,2 for infliximab).The frequency of adverse events were comparable between rhTNFR:Fc and Infliximab injection in immediate adverse reactions (P=0.31).One hundred and twenty-six (69 rhTNFR:Fc,57 infliximab) patients had long-term usage,and were followed-up at week 8,12,52,104,39 patients had adverse reactions:20 (51.3％) for rhTNFR:Fc,19(48.7％) for infliximab.Thirty-seven patients had infectious events(94.9％ ),1 neurological event(2.6％),and 1 patient had tuberculosis relapse (2.6％).Outcomes were comparable with rhTNFR:Fc and infliximab in long-term usage(P=0.69).ConclusionAttention should be paid to the above events in Chinese Han patients with ankylosing spondylitis who were treated with TNF-α blocker treatment.Special attention should be paid to those patients who are in their third or fourth injection.The occurrence of immediate reaction or long-term adverse events between rhTNFR:Fc and infliximab are comparable.

Background::Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) can profoundly affect the mental health of the people living with HIV (PLWH), with higher rates of anxiety, depression, and sleep disturbances. The disparities in neuropsychological problems evaluated by physicians and self-assessed by patients are still unknown.Methods::A total of 5000 PLWH and 500 physicians from 167 hospitals were enrolled in this cross-sectional study from September 2022 to February 2023. 4-Item Patient Health Questionnaire (PHQ-4) was used for the evaluation of depressive issues and anxiety issues by PLWH. Each physician assessed 10 PLWH under their care for the presence of depressive or anxiety issues. The primary outcomes of this study are the concordance rates on the depressive issues and anxiety issues evaluation between physicians and PLWH. The Cohen’s kappa test was used to assess the agreement between physicians and PLWH.Results::The concordance rate for the evaluation of depressive issues is 73.84% (95% confidence interval [CI]: 72.60-75.04%), and it is significantly different from the expected rate of 80% ( P <0.001). Similarly, the concordance rate for the evaluation of anxiety issues is 71.74% (95% CI: 70.47-72.97%), which is significantly different from the expected rate of 80% as per the null hypothesis ( P <0.001). The overestimation rate by physicians on depressive issues is 12.20% (95% CI: 11.32-13.14%), and for anxiety issues is 12.76% (95% CI: 11.86-13.71%). The mismatch rate for depressive issues is 26.16% (95% CI: 24.96-27.40%), and for anxiety issues is 28.26% (95% CI: 27.02-29.53%). The underestimation rate by physicians on depressive issues is 13.96% (95% CI: 13.03-14.95%), and for anxiety issues is 15.50% (95% CI: 14.52-16.53%). For the treatment regiments, PLWH sustained on innovative treatment regimen (IR) related to a lower prevalence of depressive issues (odds ratio [OR] = 0.71, 95% CI: 0.59-0.87, P = 0.003) and a lower prevalence of anxiety issues (OR = 0.63, 95% CI: 0.52-0.76, P <0.001). PLWH switch from conventional treatment regimen (CR) to IR also related to a lower prevalence of depressive issues (OR = 0.79, 95% CI: 0.64-0.98) and a lower prevalence of anxiety issues (OR = 0.81, 95% CI: 0.67-0.99). Conclusion::Nearly one in three PLWH had their condition misjudged by their physicians. The findings underscore the need for improved communication and standardized assessment protocols in the care of PLWH, especially during the acute phase of HIV infection.
