慢性乙型肝炎患者外周血单个核细胞内HBV-DNA与中医证型关系的研究

目的探讨慢性乙型肝炎患者血清乙肝病毒脱氧核糖核酸（HBV—DNA）及外周血单个核细胞（PBMCs）中HBV．DNA感染与中医证型的关系。方法220例慢性乙型肝炎患者进行乙肝标志物检查、血清HBV—DNA（定量）及PBMCs中HBV—DNA检测（PCR方法），经中医辨证确定205例患者的中医证型。结果研究发现各中医证型血清HBV—DNA（定量）≥1．0×10^5拷贝／mL（高病毒栽量）患者比例由小到大排列依次为：湿热中阻证〈瘀血阻络证〈肝肾阴虚证〈脾肾阳虚证〈肝郁脾虚证。肝郁脾虚证组血清HBV—DNA（定量）≥1．0×10^5拷贝／mL患者比例最高（占82．5％），与湿热中阻证组（占55．2％）差异有显著性（P〈0．01）。各中医证型PBMCs中HBV—DNA感染患者比例由小到大排列依次为：肝肾阴虚证〈湿热中阻证〈脾肾阳虚证〈瘀血阻络证〈肝郁脾虚证。肝郁脾虚证组PBMCs中HBV．DNA感染患者比例最高（占77．2％），与肝肾阴虚证（占27．3％）、湿热中阻证（占34．3％）、瘀血阻络证（占53．1％）比较，差异均有显著性（P〈0．01）。结论血清HBV—DNA（定量）及PBMCs中HBV—DNA感染与中医证型之间有一定关系，肝郁脾虚证组血清HBV．DNA（定量）≥1．0×10^5拷贝／mL患者比例及PBMCs中HBV—DNA感染患者比例最高，治疗应注重扶正祛邪。

Relationship between HBV-DNA in Peripheral Blood Mononuclear Cells and Syndrome Types of TCM in Chronic Hepatitis B Patients

OBJECTIVE: To study the relationship between TCM syndrome type and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs) in chronic hepatitis B (CHB) patients. METHODS: The serum HBV markers,HBV-DNA levels in serum and PBMCs, were quantitatively detected in 220 CHB patients by PCR method, and TCM syndrome type of 205 patients were differentiated. RESULTS: Arranged from low to high, the percentages of CHB patients with the serum HBV-DNA > or = 1.0 x l0(5) copy/mL (high viral loading) in the five syndrome types were as follows: damp-heat retention in middle-jiao syndrome (DHRS, 55.2%), blood stasis blocking collateral syndrome (BSBC), Gan-Shen yin deficiency syndrome (GSYS), Pi-Shen yang deficiency syndrome (PSDS) and Gan stagnation with Pi deficiency syndrome (GSPS, 82.5%), the difference was significant between DHRS and GSPS; those with HBV-DNA in PBMCs infection were: GSYS (27.3%), DHRS (34.3%), BSBC (53.1%) and GSPS (77.2%). The percentage in GSPS was the highest, which was significantly different to that in other syndromes. CONCLUSION: Amount of serum HBV-DNA and PBMCs HBV-DNA infection has certain correlation with the TCM syndrome type of CHB. The highest percentage of patients with HBV-DNA > or = 1.0 x l0(5) copy/mL and PBMCs HBV-DNA infection presented in CHB patients of GSPS type. We should pay more attention to strengthen genuine qi to eliminate pathogenic factors in treatment of CHB.
