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.

ObjectiveTo explore the mechanism of Shenqi Gualou Xiebai Banxia Decoction （参芪瓜蒌薤白半夏汤， SGXBD） in the treatment of atherosclerosis. MethodsThirty Apolipoprotein E gene knockout （ApoE^-/-） mice were randomly divided into five groups： model group， rosuvastatin group， low-， moderate-， and high-dose SGXBD， with six mice in each group. They were fed a high-fat diet to prepare for atherosclerosis model. Another six C57BL/6J wild-type mice were set as the blank group. After modeling， the low-， moderate-， and high-dose SGXBD groups were gavaged with 6.46， 12.92， and 25.84 g/（kg·d） of SGXBD， respectively. The rosuvastatin group was given 1.55 mg/（kg·d） of rosuvastatin tablets by gavage. The blank group and model group were given 0.5 ml saline by gavage. After four weeks， the total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） in the serum of each group were detected， as well as TC and TG in the liver. The serum bile acid level was detected by enzyme cycling colorimetry. The mRNA and protein expression of peroxisome proliferator-activated receptor γ （PPARγ）， sterol regulatory element-binding protein 2 （SREBP2）， 3-hydroxy-3-methylglutaryl-CoA reductase （HMGCR）， and cholesterol 7α-hydroxylase （CYP7A1） in the liver were detected by real-time RT-PCR and Western blot. ResultsCompared with the blank group， the model group showed significant increases in serum TG， TC， and LDL-C levels， and significant decreases in HDL-C and bile acid levels； the levels of TG and TC in the liver， as well as the expression of SREBP2 and HMGCR proteins and mRNA in the liver significantly increased， while the expression of PPARγ and CYP7A1 proteins and mRNA significantly decreased （all P＜0.01）. Compared with the model group， the rosuvastatin group and high-dose SGXBD group showed significant decreases in serum TG， TC， and LDL-C levels and liver TG and TC levels， and significant increases in bile acid levels； the expression of PPARγ and CYP7A1 proteins and mRNA increased， while the expression of SREBP2 and HMGCR proteins and mRNA decreased； the low-dose SGXBD group showed significant decreases in serum TC and LDL-C levels and liver TC level （P＜0.05 or P＜0.01）. Compared with the rosuvastatin group， the low-dose SGXBD group had a significantly higher liver TC level， while the high-dose SGXBD group had a significantly lower liver TC level， CYP7A1 mRNA level， and PPARγ protein expression level， and a significantly higher SREBP2 protein expression level （P＜0.05 or P＜0.01）. Compared with the low- and moderate-dose groups， the high-dose SGXBD group had significantly lower serum TG and liver TC levels （P＜0.05）. ConclusionSGXBD may improve blood lipid levels and exhibit anti-atherosclerotic effects by regulating the protein level of PPARγ and simultaneously affecting the synthesis of liver cholesterol and the conversion of cholesterol to bile acids.

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.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

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.
