肺阳虚证复兴之初探

卵巢是女性重要的内生殖器,通过从隶属关系、藏泄功能、卵巢藏泄失司与排卵功能障碍3个方面论述卵巢应为奇恒之脏,其功能分藏泄两方面,受肝的疏泄和肾的封藏调节,藏泄失常与卵巢排卵障碍有密切关系。     

EGFR/PI3K/Akt细胞信号传导通路与肿瘤

表皮生长因子受体(EGFR)/磷脂酰肌醇3-激酶(PI3K)/蛋白激酶B(PKB,也称Akt)信号通路是生物体内一条非常重要的生存信号通路。EGFR通过二聚化后刺激Ras蛋白,导致磷酸化级联反应的发生来激活PI3K/Akt信号通路,从而引起肿瘤的发生发展。本文从EGFR/PI3K/Akt信号传导通路对肿瘤的调节机制等多个方面综述了EGFR/PI3K/Akt信号通路与肿瘤的关系。     

Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study

Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.     

中药制剂对消化性溃疡QOUH及EGF、TNF—α表达的影响

目的：探讨中药制剂对消化性溃疡溃疡愈合质量及EGF、TNF-α表达的影响。方法：选择60例HP阳性消化性溃疡患者,随机分为常规治疗组和中药制剂治疗组各30例,常规治疗组给予三联疗法,中药制剂治疗组在常规治疗组治疗的基础上同时服用中药制剂,治疗结束后复查胃镜及相关检测指标,1年后进行随访。结果：治疗前两组患者EGF、TNF-α表达无明显差异,治疗后,两组患者EGF表达均较治疗前明显提高,TNF-α表达均较治疗前明显降低,并且治疗后中药制剂治疗组EGF表达明显高于常规治疗组,TNF-α表达明显低于常规治疗组。中药制剂治疗组愈合率、HP根除率明显高于常规治疗组。1年后随访,中药制剂治疗组复发率明显低于常规治疗组。结论：中药制剂是消化性溃疡治疗中的有效药物,能够提高溃疡愈合质量,降低复发,其机制可能与提高EGF,降低TNF-α关。     

血小板参数在鉴别诊断免疫性血小板减少症和再生障碍性贫血中的作用及其对疗效判断的应用

目的探讨血小板参数在鉴别诊断免疫性血小板减少症(ITP)及再生障碍性贫血(AA)中的作用和疗效判断的临床意义。方法收集45例ITP和49例AA患者治疗前和治疗后的抗凝静脉血,选择45例健康体检者作为对照组,检测血小板参数对ITP和AA治疗前和治疗后血小板参数结果进行比较分析。结果治疗前,ITP组和AA组PLT、PCT低于对照组(P <0. 05);MPV、PDW-SD在ITP组中高于AA组(P <0. 05),AA组高于对照组(P <0. 05);P-LCR在ITP组中高于AA组和对照组(P <0. 05)。治疗后,ITP患者PLT、PCT增高(P <0. 05),P-LCR、MPV降低(P <0. 05);AA患者P-LCR、MPV均增高(P <0. 05),而PLT、PCT持续下降,上述差异均有统计学意义(P <0. 05)。结论 P-LCR、MPV、PDW-SD在ITP患者中高于AA患者,可做为两者鉴别诊断的依据。ITP患者治疗有效后P-LCR、MPV、PDW-SD显著降低,这对判断ITP治疗效果有重要的临床意义。
