Objective To investigate the pathological significance of DEK-AP-2α interaction in HER2 overexpres-sion and breast tumorigenesis. Methods The protein level of DEK,AP-2α and HER-2 in breast tumor tissues was detected by Western blot. The interaction of DEK and AP-2α in MDA-MB-453 mammary cancer cells was detected by immuno-coprecipitation. Furthermore the impact of DEK and AP-2α on HER2 expression was investigated by siRNA in MDA-MB-453 mammary cancer cells followed by semi-quantitive RT-PCR and Western blot. Results A correlation between DEK, AP-2α and HER2 levels in breast cancer tissues were found. The interaction between DEK and AP-2α in MDA-MB-453 cells was verified by co-immunoprecipitation assay. Depletion of DEK and AP-2α in MDA-MB-453 cell by siRNA cooperatively repressed HER2 expression at both the mRNA and protein levels. Conclusion Oncogene DEK has synergestic effect with AP-2α transcriptional factor to promote HER2 overexpres-sion in breast cancer.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

OBJECTIVES:
Stroke has become the leading cause of death and disability among adults in China. This study aims to analyze the disease burden based on gender and age and the risk factors for stroke subtypes in China 2019, and to provide reference for targeted stroke prevention and control.
METHODS:
Based on 2019 data of the Global Burden of Disease (GBD), the gender and age in patients with different stroke subtypes (ischemic stroke, intracranial hemorrhage, subarachnoid hemorrhage) in China 2019 was described by using disability-adjusted life years (DALY), and attributable burden of related risk factors was analyzed.
RESULTS:
In 2019, the burden of intracranial hemorrhage was the heaviest one in China, resulting in 22.210 6 million person years of DALY, following by ischemic stroke and subarachnoid hemorrhage, resulting in 21.393 9 and 2.344 7 million person years of DALY, respectively. Among them, except the 0-14 age group, the disease burden of different subtypes of stroke in men was higher than that in women. The disease burden of ischemic stroke was increased with age in both men and women, with the heaviest disease burden in ≥70 years group. The disease burden of intracranial hemorrhage and subarachnoid hemorrhage was the heaviest in males aged 50-69 years old, and in females aged ≥70 years and 50-69 years, respectively. Metabolic factors were the main risk factors in all ages of different stroke subtypes, and the most important risk factor was high systolic blood pressure. Other risk factors were different between men and women. Smoking, high body mass index, high low-density lipoprotein, and outdoor particulate matter pollution were the main risk factors for stroke in men, while high body mass index, outdoor particulate matter pollution, and high fasting blood glucose were the main risk factors of stroke in women. The main risk were different among different age groups.
CONCLUSIONS
The burden and attributable risk factors for different stroke subtypes are discrepancy in different gender and age groups. Targeted interventions should be conducted in the future to reduce the burden of stroke.
