慢性胃炎中医证候与胃窦十二指肠运动及胃炎程度的相关性

研究慢性胃炎中医辨证分型与幽门螺杆菌 (Hp) 感染、胃粘膜炎症程度以及胃窦十二指肠消化间期移行性运动复合波之间的关系.将慢性胃炎117例,按中医辨证分为实证和虚证,实证包括脾胃湿热型 37 例和肝胃不和型 34 例,虚证包括脾胃虚弱型 26 例和胃阴不足型 20 例.均进行内镜、Hp 及病理检查,分型统计并进行显著性检验.其中 38 例用腔内测压法分别测定其消化间期移行性运动复合波 (MMC).实证组 Hp 阳性率高于虚证组,依次为:脾胃湿热型 86.5%,肝胃不和型 79.4%,脾胃虚弱型 50.0%,胃阴不足 40.0%.各型的重度胃炎所占比率依次为脾胃湿热型 54.0%,肝胃不和型 38.2%,脾胃虚弱型 19.2%,胃阴不足型 15.0%.胃粘膜炎症程度与 Hp 感染呈平行关系,与慢性胃炎虚实证密切相关.MMC 测定实证组主要表现为胃窦十二指肠收缩增强,甚至亢进紊乱;虚证组主要表现为胃窦和十二指肠Ⅱ相运动指数、收缩频率和波幅降低,Ⅲ相不出现或时间缩短、波幅降低.显示 Hp 感染、胃粘膜炎症程度以及胃窦十二指肠 MMC 与慢性胃炎中医分型可能有相关性.

The third inactivated vaccine booster dramatically enhanced SARS-CoV-2 antibody responses and did not influence the profile of prothrombotic antibody

The purpose of this study is to investigate the production of both severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-specific antibodies and autoantibodies in serum following the third booster vaccination of the inactivated COVID-19 vaccine, and to study the effect of B cell subsets with CD27 and CD38 phenotypes in peripheral blood on antibody production. Routine blood indexes, SARS-CoV-2 antibodies, platelet factor 4 and seven antiphospholipid antibodies were detected both before and 2 months after vaccination in the medical staff of the Zhongnan Hospital of Wuhan University. Peripheral blood B cell subtypes were detected before vaccination. Following immunization, the positive rate of anti-N-S1 immunoglobulin (IgG) had increased from 24.8% to 91.3% and the average antibody concentration had increased by 11 times. The positive rate of neutralizing antibody had increased from 24.8% to 91.3%, the average antibody concentration had increased by 12 times, and the primary increased anti-S1 IgG subtype was that of IgG1. Peripheral blood CD27 + CD38+ B cells were positively correlated with antibody levels after vaccination and were a predictor of the antibody response. In addition, although some indicators showed slight absolute changes, the blood parameters and antiphospholipid antibodies of most volunteers were normal both before and after COVID-19 inactivated vaccine inoculation, and there was no statistical difference in abnormal rates either before or after inoculation. Antibodies in vivo were increased after vaccination with the inactivated vaccine, and IgG1 was the main subtype involved in response to the vaccine. Vaccination with the inactivated COVID-19 vaccine did not appear to affect thrombus-related autoantibodies.
