<b>Objective:b> To investigate the rates on prevalence, awareness, treatment and control of hypertension in population older than 15 years of age in Beijing, 2013-2014. <b>Methods:b> A cross-sectional survey was conducted in Beijing between 2013-2014. Stratified multistage random sampling method was used to select representative sample of 13 057 Chinese individuals aged over 15 years, from the general population. Blood pressure was measured for three readings at sitting position after resting for at least five minutes with an average reading recorded. A standardized structured questionnaire was developed to collect history of hypertension and antihypertensive treatment. <b>Results:b> A total of 4 663 community residents aged over 15 years were hypertensive among the 13 057 individuals, with the standardized prevalence rate as 32.7%, in Beijing area. The age-standardized prevalence rates of hypertension appeared 34.6% in men and 30.8% in women. The age-and sexstandardized prevalence of hypertension rates were 33.3% in urban and 24.6% in rural areas. The prevalence of hypertension increased with age and appeared higher in men than in women, in urban than in rural residents. Among the hypertensive patients, rates of awareness, treatment and control were 66.8%, 64.6% and 31.6%, respectively. <b>Conclusion:b> High prevalence of hypertension with low rates on awareness and treatment and control, appeared in the general population of Beijing. Related strategies should be developed regarding prevention, control and management of hypertension, to reduce the burden of this disease.

[摘 要] 目的：为解决野生型B细胞成熟抗原（BCMA）被γ分泌酶切割导致表达不稳定的问题，构建抵抗γ分泌酶切割的BCMA突变体并构建靶细胞，用于评价BCMA CAR-T细胞的杀伤功能。方法：将野生型BCMA的穿膜域替换为人CD8α穿膜域，构建抵抗γ分泌酶切割的BCMA突变体（BCMA-CD8α TM），构建过表达该突变体的U266（U266BCMA Mut）、K562（K562BCMA Mut）、SKOV3（SKOV3BCMA Mut）和CHO（CHOBCMA Mut）细胞；构建装载NFAT-EGFP报告基因的BCMA CAR Jurkat细胞（BCMA-CAR-Jurkat-Reporter）与U266BCMA Mut细胞共培养，采用FCM检测该细胞中EGFP表达水平以指示NFAT激活水平，荧光素酶法检测BCMA CAR-T细胞对Luciferase标记的K562BCMA Mut细胞的杀伤作用，实时无标记动态细胞分析技术（RTCA）检测BCMA CAR-T细胞对SKOV3BCMA Mut和CHOBCMA Mut细胞的杀伤作用。结果：应用γ分泌酶抑制剂LY411575抑制γ分泌酶活性，显著增强野生型U266细胞表面BCMA表达水平，平均荧光强度上调10倍以上；但撤除抑制剂后BCMA表达水平逐渐降低（P<0.01）；BCMA-CD8α TM突变体可抵抗γ分泌酶的切割作用，在U266细胞表面稳定表达（P>0.05）；U266细胞及过表达BCMA-CD8α TM的U266细胞与BCMA-CAR-Jurkat-Reporter细胞共培养后都可激活Reporter系统、增强EGFP表达，但该效应在BCMA-CD8α TM过表达的U266细胞中更显著（P<0.01）；BCMA-CD8α TM在BCMA表达阴性的K562、SKOV3和CHO 3种靶细胞中成功过表达，且在LY411575处理下该突变体的表达水平仅有小幅度升高；荧光素酶法检测结果显示，不同效靶比下，BCMA CAR-T细胞均可特异、高效杀伤过表达BCMA-CD8α TM的K562细胞；RTCA结果显示，不同效靶比下，BCMA CAR-T细胞均可有效识别、杀伤过表达BCMA-CD8α TM的SKOV3和CHO细胞，但同等效靶比下的Mock-T细胞无此效应。结论：本实验构建的BCMA-CD8α TM突变体能够抵抗γ分泌酶的切割，在多种靶细胞表面稳定表达，为评价BCMA CAR-T细胞体外杀伤的有效性和特异性提供多种检测手段。

BAome III criteria. METHODS: After EAR3Q was developed by Asian experts by cCKGROUND/AIMS: The development-processes by regional socio-cultural adaptation of an Enhanced Asian Rome III questionnaire (EAR3Q), a cultural adaptation of the Rome III diagnostic questionnaire (R3DQ), and its translation-validation in Asian languages are presented. As English is not the first language for most Asians, translation-validation of EAR3Q is essential. Hence, we aimed to culturally adapt the R3DQ to develop EAR3Q and linguistically validate it to show that the EAR3Q is able to allocate diagnosis according to Ronsensus, it was translated into Chinese, Hindi-Telugu, Indonesian, Korean, and Thai, following Rome Foundation guidelines; these were then validated on native subjects (healthy [n = 60], and patients with irritable bowel syndrome [n = 59], functional dyspepsia [n = 53] and functional constipation [n = 61]) diagnosed by clinicians using Rome III criteria, negative alarm features and investigations. RESULTS: Experts noted words for constipation, bloating, fullness and heartburn, posed difficulty. The English back-translated questionnaires demonstrated concordance with the original EAR3Q. Sensitivity and specificity of the questionnaires were high enough to diagnose respective functional gastrointestinal disorders (gold standard: clinical diagnoses) in most except Korean and Indonesian languages. Questionnaires often uncovered overlapping functional gastrointestinal disorders. Test-retest agreement (kappa) values of the translated questionnaires were high (0.700-1.000) except in Korean (0.300-0.500) and Indonesian (0.100-0.400) languages at the initial and 2-week follow-up visit. CONCLUSIONS: Though Chinese, Hindi and Telugu translations were performed well, Korean and Indonesian versions were not. Questionnaires often uncovered overlapping FGIDs, which were quite common.

BACKGROUND/AIMS: There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. METHODS: Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. RESULTS: Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. CONCLUSIONS: Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.
