Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Conversion therapy such as transcatheter arterial chemoembolization(TACE)and hepatic arterial infusion chemotherapy(HAIC)is the main treatment method to transform unresectable advanced liver cancer into resectable liver cancer,which can not only effectively increase the survival rate of patients,but also provide patients with the opportunity of liver transplantation.However,pain is a major complication of TACE and HAIC in the treatment of liver cancer,and the incidence of abdominal pain after TACE is from 19.3%to 71.2%,and nearly 64.6%of patients have different degrees of pain during HAIC,which seriously affects the quality of life of patients and shortens their survival time.At present,the mechanism of pains caused by TACE and HAIC is not clear,and it may be related to local liver tissue swelling after embolic agents block the tumor blood supply artery,increased pressure in the liver tissue envelope or traction of the mass capsule,chemical stimulation of the hepatic artery by embolic agents and antineoplastic drugs,thrombosis adjacent to the normal organs,and visceral pain sensitization caused by intestinal ischemia.There are two main intervention measures for pain,one of which is lidocaine,opioids,non-steroidal anti-inflammatory drugs and glucocorticoids,and the other is wrist and ankle acupuncture and traditional Chinese medicine decoction,but their treatment effects are uneven.This article summarizes the status and treatment of pain caused by TACE and HAIC therapies for liver cancer,in order to provide reference for its clinical treatment.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Objective To investigate the effect of glycine N-methyl transferase (GNMT)on intrauterine adhesion (IUA)fibrosis and its related mechanism.Methods In vivo experiment:A total of 36 healthy female SD rats (SPF grade,6～8 weeks old and weighing from 180～220 g)were subjected in this study.IUA model of SD rats and IUA model of GNMT overexpressed rats were established.RT-qPCR and immunofluorescence assay were applied to detect GNMT expression level in normal uterus and model group.RT-qPCR and Western blotting were used to detect the mRNA and protein levels of fibrosis-related molecules and the activation of TGF-β1/Smad3 signaling pathway in each group.The number of endometrial glands in each group was observed by HE staining.Masson staining was used to analyze the severity of endometrial fibrosis in each group.In vitro experiment:transformed human endometrial stromal cells (THESCs)fibrotic phenotype model was constructed using TGF-β1,and THESCs stably transfected with GNMT overexpression lentvirus were treated with TGF-β1.RT-qPCR and Western blotting were used to detect the mRNA and protein expression of fibrosis-related molecules.The expression of TGF-β1/Smad3 signaling pathway was detected by Western blotting.TGF-β1/Smad3 signaling pathway was activated by TGF-β1/Smad signaling pathway activator (SRI-011381),and the expression of TGF-β1/Smad3 signaling pathway and key molecular proteins of fibrosis phenotype was measured with Western blotting.Results In vivo experiment,the mRNA and protein expression levels of GNMT were significantly decreased in the IUA rats than the control rats (P<0.05).Overexpression of GNMT decreased the mRNA and protein levels of fibrosis related molecules,Collagen Ⅰ,Collagen Ⅲ and FN in the IUA rats (P<0.05),and decreased the phosphorylation levels of TGF-β1 and its downstream Smad3 protein (P<0.05).HE and Masson staining showed that overexpression of GNMT could increase the number of endometrial glands and reduce the severity of fibrosis in the IUA rats (P<0.05).In vitro experiments:overexpression of GNMT decreased the mRNA and protein levels of Collagen Ⅰ,Collagen Ⅲ and FN associated with fibrotic phenotype of THESCs (P<0.05),and reduced the phosphorylation level of Smad3 protein,downstream of TGF-β1 (P<0.05).After activation of TGF-β1/Smad3 signaling pathway,the protein levels of TGF-β1/Smad3 signaling pathway and downstream fibrosis phenotype molecules,Collagen Ⅲ and FN,were significantly decreased in the LV-GNMT+SRI-011381 group.Conclusion Overexpression of GNMT can inhibit endometrial fibrosis by regulating TGF-β1/Smad3 signaling pathway,thus achieving therapeutic effect on IUA.

Objective:To investigate the effect of high-fat and low-carbohydrate diet combined with radiotherapy on the tumor microenvironment of mice with lung xenografts.Methods:C57BL/6J mice were selected to establish the Lewis lung cancer model, and they were divided into the normal diet group, the high-fat and low-carbohydrate diet group, the normal diet + radiotherapy group, and the high-fat and low-carbohydrate diet + radiotherapy group, with 18 mice in each group. The mice in the normal diet group and the normal diet + radiotherapy group were fed with the normal diet with 12.11% fat for energy supply, and the mice in the high-fat and low-carbohydrate diet group and the high-fat and low-carbohydrate diet + radiotherapy group were fed with high-fat and low-carbohydratediet with 45.00% fat for energy. On the 12th to 14th days, the tumor sites of the mice in the normal diet + radiotherapy group and the high-fat and low-carbohydrate diet + radiotherapy group were treated with radiotherapy, and the irradiation dose was 24 Gy/3f. The body weight, tumor volume, blood glucose and blood ketone level, liver and kidney function, and survival status of the mice were observed and monitored. Immunohistochemical staining was used to detect the tumor-associated microangiogenesis molecule (CD34) and lymphatic endothelial hyaluronan receptor 1 (LYVE-1), Sirius staining was used to detect collagen fibers, and multiplex immunofluorescence was used to detect CD8 and programmed death-1 (PD-1). Expression of immune cell phenotypes (CD3, CD4, CD8, and Treg) was detected by flow cytometry.Results:On the 27th day after inoculation, the body weigh of the common diet group was(24.78±2.22)g, which was significantly higher than that of the common diet + radiotherapy group [(22.15±0.48)g, P=0.030] and high-fat low-carbohydrate diet + radiotherapy group [(22.02±0.77)g, P=0.031)]. On the 15th day after inoculation, the tumor volume of the high-fat and low-carbohydrate diet + radiotherapy group was (220.88±130.05) mm 3, which was significantly smaller than that of the normal diet group [(504.37±328.48) mm 3, P=0.042)] and the high-fat, low-carbohydrate diet group [(534.26±230.42) mm 3, P=0.016], but there was no statistically significant difference compared with the normal diet + radiotherapy group [(274.64±160.97) mm 3]. In the 4th week, the blood glucose values of the mice in the high-fat and low-carbohydrate diet group were lower than those in the normal diet group, with the value being (8.00±0.36) mmol/L and (9.57±0.40) mmol/L, respectively, and the difference was statistically significant ( P＜0.05). The blood ketone values of the mice in the high-fat and low-carbohydrate diet group were higher than those in the normal diet group, with the value being (1.00±0.20) mmol/L and (0.63±0.06) mmol/L, respectively, in the second week. In the third week, the blood ketone values of the two groups of mice were (0.90±0.17) mmol/L and (0.70±0.10) mmol/L, respectively, and the difference was statistically significant ( P＜0.05). On the 30th day after inoculation, there were no significant differences in aspartate aminotransferase, alanine aminotransferase, creatinine, and urea between the normal diet group and the high-fat, low-carbohydrate diet group (all P＞0.05). The hearts, livers, spleens, lungs, and kidneys of the mice in each group had no obvious toxic changes and tumor metastasis. In the high-fat and low-carbohydrate diet + radiotherapy group, the expression of CD8 was up-regulated in the tumor tissues of mice, and the expressions of PD-1, CD34, LYVE-1, and collagen fibers were down-regulated. The proportion of CD8 + T cells in the paratumoral lymph nodes of the high-fat and low-carbohydrate diet + radiotherapy group was (25.13±0.97)%, higher than that of the normal diet group [(20.60±2.23)%, P＜0.050] and the normal diet + radiotherapy group [(19.26±3.07)%, P＜0.05], but there was no statistically significant difference with the high-fat and low-carbohydrate diet group [(22.03±1.75)%, P＞0.05]. The proportion, of CD4 + T cells in the lymph nodes adjacent to the tumor in the normal diet + radiotherapy group (31.33±5.16)% and the high-fat and low-carbohydrate diet + radiotherapy group (30.63±1.70)% were higher than that in the normal diet group [(20.27±2.15)%, P＜0.05] and the high-fat and low-carbohydrate diet group (23.70±2.62, P＜0.05). Treg cells accounted for the highest (16.58±5.10)% of T cells in the para-tumor lymph nodes of the normal diet + radiotherapy group, but compared with the normal diet group, the high-fat and low-carbohydrate diet group, and the high-fat and low-carbohydrate diet + radiotherapy group, there was no statistically significant difference (all P＞0.05). Conclusion:High-fat and low-carbohydrate diet plus radiotherapy can enhance the recruitment and function of immune effector cells in the tumor microenvironment, inhibit tumor microangiogenesis, and thus inhibit tumor growth.

Objective To investigate the distribution of traditional Chinese medicine(TCM)constitution types in patients with perimenopause metabolic syndrome in Guangzhou based on the Stages of Reproductive Aging Workshop+10(STRAW+10),so as to provide a theoretical basis for TCM constitution regulation for patients with PMS.Methods According to the diagnostic criteria of metabolic syndrome,a total of 90 patients with PMS were included.Based on the STRAW+10 staging criteria,the PMS patients were divided into early perimenopause group(-2 phase of STRAW+10,49 cases),late perimenopause group(-1 phase of STRAW+10,24cases),and early postmenopausal group(+la phase of STRAW+10,17 cases).Traditional Chinese Medicine Constitution Classification and Distinguishing Criteria were used to identify the TCM constitution types of all the subjects.At the same time,the Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)were used for scoring anxiety and depression.The distribution of TCM constitution types in patients with different STRAW+10 stages was analyzed,and the SAS and SDS scores of patients with different STRAW+10 stages were compared.Results(1)The primary TCM constitution types in the early perimenopause group(-2 phase of STRAW+10)were yang deficiency constitution(14 cases,29.79％),balanced constitution(10 cases,21.28％),yin deficiency constitution(six cases,12.76％)and blood stasis constitution(six cases,12.76％).In the late perimenopause group(-1 phase of STRAW+10),the primary TCM constitution types were yang deficiency constitution(six cases,25.00％),balanced constitution(four cases,16.66％),blood stasis constitution(four cases,16.66％),qi deficiency constitution(three cases,12.50％)and phlegm-damp constitution(three cases,12.50％).In the early postmenopausal group(+la phase of STRAW+10),the primary TCM constitution types were yang deficiency constitution(seven cases,46.67％),balanced constitution(two cases,13.33％),phlegm-damp constitution(two cases,13.33％),blood stasis constitution(two cases,13.33％),qi deficiency constitution(one case,6.67％)and qi stagnation constitution(one case,6.67％).(2)The SAS score and SDS score in the early perimenopause group(-2 phase of STRAW+10)were(34.55±7.46)points and(35.55±10.61)points,respectively,which were higher than those in the late perimenopause group(-1 phase of STRAW+10)[(33.83±7.73)points and(35.46±11.35)points,respectively]and in the early postmenopausal group(+la phase of STRAW+10)[(35.65±8.67)points and(36.59±12.07)points,respectively].All of the scores were higher than the overall average level.Conclusion The TCM constitution of patients with perimenopause metabolic syndrome is predominated by yang deficiency constitution.The percentage of the balanced constitution gradually decreases with the progression of STRAW+10 staging,and the biased constitutions gradually develop from yin deficiency constitution and blood stasis constitution into qi deficiency constitution and phlegm-damp constitution,and then into phlegm-damp constitution and blood stasis constitution again.With the progression of the stage,the deficiency in the fundamental of the PMS patients becomes more deficient and the pathogens of excess in the incidental also grow.
