目的:探讨细胞因子信号转导抑制因子3(suppressor of cytokine signaling 3,SOCS3)介导的蛋白酪氨酸激酶1(janus protein kinase 1,JAK1)/信号转导与转录激活子5(signal transducer and activator of transcription 5,STAT5)炎症通路表... 目的:探讨细胞因子信号转导抑制因子3(suppressor of cytokine signaling 3,SOCS3)介导的蛋白酪氨酸激酶1(janus protein kinase 1,JAK1)/信号转导与转录激活子5(signal transducer and activator of transcription 5,STAT5)炎症通路表达对慢性湿疹血虚风燥证患者的影响及壮医脐环穴针刺法对其的干预作用。方法:选择62例慢性湿疹血虚风燥证患者,随机分为对照组和观察组各31例,实际完成对照组30例,观察组28例,并选取26名健康体检者作为正常组。对照组给予复方甘草酸苷片口服和糠酸莫米松乳膏外涂治疗,观察组采用壮医脐环穴针刺法治疗,疗程为4周。观察两组临床疗效,湿疹面积及严重度指数评分(eczema area and severity index,EASI),视觉模拟评分(visual analogue scale,VAS),外周血单个核细胞(peripheral blood mononuclear cell,PBMC)中SOCS3、JAK1、磷酸化蛋白酪氨酸激酶1、STAT5、磷酸化信号转导与转录激活子5(pSTAT5)蛋白表达,血清白细胞介素4(interleukin-4,IL-4)、白细胞介素6(interleukin-6,IL-6)、白细胞介素10(interleukin-10,IL-10)水平。结果:观察组临床总有效率[85.71%(24/28)]优于对照组[60.00%(18/30)](P<0.05)。治疗后,两组EASI、VAS评分较治疗前均降低(P<0.05),且观察组降低降程大于对照组(P<0.05)。两组治疗前PBMC中SOCS3、JAK1、pJAK1、STAT5、pSTAT5蛋白表达量均高于正常组(P<0.05);治疗后两组SOCS3蛋白表达量均较治疗前升高,JAK1、pJAK1、STAT5、pSTAT5蛋白表达量降低(P<0.05),观察组改善程度优于对照组(P<0.05)。两组治疗前血清IL-4、IL-6、IL-10水平均高于正常组(P<0.05),治疗后两组上述指标均较治疗前降低(P<0.05),且观察组低于对照组(P<0.05)。结论:壮医脐环穴针刺法能改善慢性湿疹血虚风燥证患者的临床症状,提高临床疗效,其机理与调控细胞内SOCS3-JAK1/SATA5信号通路表达,抑制患者的炎症反应有关。 展开更多

Based on observations and Coupled Model lntercomparison Project Phase 5 (CMIP5) results, multidecadal variations and trends in annual mean surface air temperature anomalies (SATa) at global, hemispheric, and hemispheric land and ocean scales in the past and under the future scenarios of two representative concentration pathways (RCPs) are analyzed. Fifteen models are selected based on their performances in capturing the temporal variability, long-term trend, multidecadal variations, and trends in global annual mean SATa. Observational data analysis shows that the multidecadal variations in annual mean SATa of the land and ocean in the northern hemisphere (NH) and of the ocean in the southern hemisphere (SH) are similar to those of the global mean, showing an increase during the 1900-1944 and 1971-2000 periods, and flattening or even cooling during the 1945-1970 and 2001-2013 periods. These observed characteristics are basically reproduced by the models. However, SATa over SH land show an increase during the 1945-1970 period, which differs from the other hemispheric scales, and this feature is not captured well by the models. For the recent hiatus period (2001-2013), the projected trends of BCC-CSM1-1-m, CMCC-CM, GFDL-ESM2M, and NorESM1-ME at the global and hemispheric scales are closest to the observations based on RCP4.5 and RCP8.5 scenarios, suggesting that these four models have better projection capability in SATa. Because these four models are better at simulating and projecting the multidecadal trends of SATa, they are selected to analyze future SATa variations at the global and hemispheric scales during the 2006-2099 period. The selected multi-model ensemble (MME) projected trends in annual mean SATa for the globe, NH, and SH under RCP4.5 (RCP8.5) are 0.17 (0.29) ℃, 0.22 (0.36) ℃, and 0.11 (0.23) ℃-decade-1 in the 21st century, respectively. These values are significantly lower than the projections of CMIP5 MME without model selection. 展开更多
