Objectives To investigate the role of angiogenic T cells (Tang) and endothelial progenitor cells (EPC) in the pathogenesis of preeclampsia. To explore the relationship between Tang and EPC. Methods From Mar 2013 to Aug 2014, 40 patients diagnosed preeclampsia (PE) and delivered in Hunan Provincial People′s Hospital. A total of 20 of them were defined as the mild preeclampsia group and the other 20 cases were recruited as the severe preeclampsia group. And 24 healthy pregnant women wererecruited as the control group. The percentage of Tang and EPC in peripheral blood mononuclear cells (PBMC) were determinated by flow cytometry between 28 and 40 gestational weeks. Results (1) There was no significant difference in the age, pre-pregnancy body mass index(Pre-BMI) or gestational age among the three groups (P>0.05). The differences of blood pressure among the three groups were statistically significant (P<0.05). The gestational week at delivery, the birthweight of the neonates and the 1 minute Apgar score in the severe preeclampsia group were lower than those in the mild preeclampsia group and the control group, with statistically significant differences (P<0.05). The morbidity of neonatal asphyxia in the severe preeclampsia group was 35%(7/20);and in the mild preeclampsia group it was 5%(1/20), with statistically significant difference( P<0.05). (2) The percentage of Tang in maternal peripheral blood was(52.7 ± 8.0)%, (47.5 ± 8.8)% and (45.5 ± 8.7)% in the control group, the mild preeclampsia group and the severe preeclampsia group, respectively. The difference among the three groups was significant (F=4.248,P<0.05), and SNK q analysis showed there was significant difference between the control group and the severe preeclampsia group(P<0.05).While there was no statistically significant difference between the mild and the severe preeclampsia group, nor between the control group and the mild preeclampsia group(P>0.05). (3) The percentage of EPC in maternal peripheral blood was (0.16±0.07)%, (0.09±0.07)%and (0.08±0.05)%in the control group, the mild and the severe preeclampsia group, respectively. Analysis of variance showed that difference among the three groups was significant (F=9.351, P<0.05). The percentage of EPC in the mild or the severe preeclampsia group was significantly higher than that of the control group(P<0.05). (4) There was no statistically significant correlation between the Tang level and the EPC level in the control group ( r=-0.325, P>0.05). In the preeclampsia group (including mild and severe cases), there was positive correlation between the Tang level and EPC level (r=0.667, P<0.01). The positive correlation between Tang level and EPC level were proved respectively in the mild preeclampsia group (r=0.803, P<0.01) and the severe preeclampsia group (r= 0.520, P<0.05). Conclusions The number of Tang had some correlation with the pathogenesis of preeclampsia. The percentage of Tang had positive correlation with the level of EPC in women with preeclampsia. Tang might have some influence on the change of EPC′ level. Tang together with EPC were likely to contribute to the angiogenesis in preeclampsia.

The key pathogenesis of coronary heart disease (CHD) is spleen deficiency and phlegm stasis, and dysfunctional high-density lipoprotein (dys-HDL) may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein (HDL), it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL; and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways, namely, mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells, thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency, and spleen deficiency makes foundation for the production of dys-HDL; dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen, resolving phlegm, and dispelling stasis, is proposed as an important principle in the treatment of CHD by traditional Chinese medicine, which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL, thus revealing the scientific connotation of this method, and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.

OBJECTIVE To explore the enhancement effect of Linggui zhugan decoction (LGZG) regulating autophagy on doxorubicin (DOX) against non-alcoholic fatty liver disease-hepatocellular carcinoma (NAFLD-HCC). METHODS C57BL/6 mice were randomly divided into blank group, NAFLD-HCC group, LGZG group, DOX group and DOX+LGZG group, with 10 mice in each group. The NAFLD-HCC model was established by intraperitoneal injection of diethylnitrosamine (50 mg/kg) and high-fat diet. The blank group was injected with the same amount of normal saline and fed with ordinary diet. After modeling, administration groups were given LGZG aqueous extract (20 g/kg) intragastrically and/or DOX solution intraperitoneally (8 mg/kg); the blank group and NAFLD-HCC group were given a constant volume of normal saline intragastrically, once a day, for 4 consecutive weeks. The general condition of mice (No.2022-BS-197) was monitored during modeling and drug intervention. After drug intervention, body weight, liver weight and liver coefficient of mice were detected. The histopathologic morphology and fibrosis degree of liver tissue in mice were observed; the levels of blood lipid [the levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)], the serum contents of alpha fetoprotein (AFP) and carcinoembryonic antigen (CEA), and the expressions of marker of proliferation Ki-67, B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X (Bax) in liver tissue were all detected as well as protein expressions of microtubule-associated proteins 1A and 1B (LC3), Beclin1 and selective autophagy adopt proteins P62. RESULTS Compared with the blank group, the activity of mice decreased gradually as time in the NAFLD-HCC group; mental fatigue, disheveled and matte hair were observed, and body weight decreased significantly (P<0.05); liver weight had an upward trend, and liver coefficient increased significantly (P<0.05). The inflammatory cells of liver tissue were infiltrated, with some cells showing ballooning and small cell hyperplasia, and the degree of liver fibrosis was worsened; serum levels of TC, TG and LDL-C, AFP and CEA contents increased significantly, while HDL-C level decreased significantly (P<0.05). The protein expressions of Ki-67 and Bcl-2 in liver tissue were increased significantly (P<0.05), while the protein expression of Bax decreased. The protein expression of Beclin1 in liver tissue decreased significantly (P<0.05); LC3Ⅱ/ LC3Ⅰ decreased, while the expression of P62 protein increased. Compared with the NAFLD-HCC group, the above indexes of mice were improved to different extents in the DOX group, LGZG group and DOX+LGZG group, and the intervention effect of DOX combined with LGZG were better than those of DOX. CONCLUSIONS LGZG combined with DOX can synergically promote the apoptosis of tumor cells, enhance the sensitivity of NAFLD-HCC chemotherapy, and effectively slow down the occurrence and development of NAFLD-HCC. The mechanism may be related to the regulation of autophagy in tumor cells.
