Objective: To analyze the prevalence trends of different types of elevated blood pressure and their association with nutritional status among primary and secondary school students in Inner Mongolia from 2019 to 2024, providing references for targeted prevention strategies. Methods: From September 2019 to 2024, a stratified random cluster sampling method was used to select 12 primary and secondary schools from each league city in Inner Mongolia Autonomous Region. A total of 177 108, 137 758, 190 182, 180 084 , 188 056, 180 351 primary and secondary school students (excluding grades one to three of primary school) were included for physical examination. The correlation between their nutritional status and high blood pressure was analyzed based on the basic situation of 129 821 primary and secondary school students who completed a questionnaire survey at the same time in 2024. Statistical analysis was conducted using a Chi-square test and multiple Logistic regression model. Results: From 2019 to 2024, the detection rates of elevated blood pressure were 13.60%, 13.68%, 17.60%, 17.24%, 14.77% and 15.96%, respectively. The rates for isolated systolic hypertension were 4.24%, 5.83%, 7.26%, 7.19%, 6.24% and 6.93%; isolated diastolic hypertension rates were 6.38%, 4.99%, 6.23 %, 6.41%, 5.39% and 5.66%; and combined systolic and diastolic hypertension rates were 2.97%, 2.86%, 4.11%, 3.65%, 3.14 % and 3.36%. Multivariate Logistic regression analysis showed that girls, junior high school, senior high school, overweight, and obesity were positively associated with elevated blood pressure risk ( OR =1.27, 1.25, 1.32, 1.66, 3.07, all P <0.05); conversely, county residence, Mongolian ethnicity, and other ethnicities showed negative associations ( OR =0.90, 0.93, 0.90, all P <0.05). Conclusions Overweight and obesity among children and adolescents are closely related to various types of elevated blood pressure. Prevention strategies should prioritize effectively controlling weight issues among children and adolescents, thereby effectively reducing the incidence of elevated blood pressure.

Objective:To understand the current and integrated disease burden and economic burden caused by breast cancer in females in China.Methods:Based on six updated data sources, including the series of Chinese Cancer Registry Annual Report, China Death Cause Surveillance Datasets, China Health Statistical Yearbook, GLOBOCAN, Cancer Incidence in Five Continents, Global Burden of Disease Study (GBD), the information about incidence, mortality and disability adjusted life years (DALY) of breast cancer were extracted for the analysis on the current incidence and time trend of breast cancer and predicted disease burden of breast cancer in females in China. Software Joinpoint was used for time trend analysis. The data of economic burden were systematically updated and analyzed by literature review.Results:1) GLOBOCAN 2022 estimated that the age-standardized incidence rate (ASIR) age-standardized mortality rate (ASMR) and one- year prevalence rate of breast cancer in females were 33.0/100 000, 6.1/100 000 and 40.1/100 000, respectively, in China in 2022. According to Chinese Cancer Registry Annual Report, the ASIR and ASMR were 28.4/100 000 and 5.8/100 000, respectively, in 2018. The China Death Cause Surveillance Datasets showed that the ASMR was 4.5/100 000 in 2021, and the urban to rural area mortality ratio was 1.2∶1. GBD reported that the DALYs of breast cancer were 2.921 million in China in 2021, accounting for 14.4% of the global total. 2) Chinese Cancer Registry Annual Report data showed that the ASIR and ASMR of breast cancer decreased by 2.1% and 11.4%, respectively, in China from 2009 to 2018, while increased by 43.9% and 8.2% in rural area, respectively. The Joinpoint analysis showed that the average annual percentage change (AAPC) of ASIR and ASMR in China were -0.2% ( P>0.05) and -1.6% ( P<0.05). The AAPC of ASIR and ASMR in rural area were 3.9% ( P<0.05) and 0.6% ( P>0.05), and -0.3% ( P>0.05) and -1.2% ( P<0.05) in urban area, respectively. China Health Statistical Yearbook data showed that the urban ASMR decreased by 12.3% from 2014 to 2021 with AAPC of -2.6% ( P<0.05). 3) The GLOBOCAN 2022 predicted that, the breast cancer case count and death count in China would be 387 776 and 111 133 by 2050, an increase of 8.6% and 48.2%, respectively, compared with 2022, the increases would be more obvious in people over 65 years old, an increase of 80.8% and 124.9%, respectively. 4) Thirteen individual- based studies reported that the median medical expenditure per patient ( M=21 000 to 39 000 Yuan) and length of hospital stay ( M=11.0 to 30.5 days) for breast cancer treatment decreased from 2010 to 2019, while the average medical expenditure per visit ( M=9 000 to 23 000 Yuan) showed an upward trend. There was only one national-level analysis, which showed that the treatment cost of breast cancer was 25.24 billion Yuan in China in 2018, accounting for 6.4% of the total cancer treatment cost. Conclusions:According to the above updated multi-source data, the incidence and mortality of female breast cancer in China were stable in the past ten years, but the increasing trend in rural area should be noted. The direct medical expenditure of breast cancer treatment per case might decrease, but the population-level economic burden would remain heavy due to population aging.

Objective:To investigate the associations of serum amyloid A (SAA) with the overall burden of cerebral small vessel disease (CSVD) and early neurological deterioration (END) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Department of Neurology, Baise People's Hospital from August 2021 to August 2023 were included retrospectively. END was defined as an increase of ≥2 in the National Institutes of Health Stroke Scale (NIHSS) score within 72 hours of onset compared to the admission score. The baseline data of patients with different CSVD burden group, as well as END and non-END groups were compared. Multivariate logistic regression analysis was used to determine the independent correlation factors for the overall burden of CSVD and END. Results:A total of 131 patients with AIS were enrolled, including 78 males (59.54%), aged 63.80±7.34 years. Sixteen patients (12.2%) were in the CSVD overall burden 0-point group, 58 (44.3%) in the 1-point group, 29 (22.1%) in the 2-point group, 22 (16.8%) in the 3-point, and 6 (4.6%) in the 4-point group; and 52 (39.7%) experienced END. There were significant differences in age, diabetes, smoking, drinking, NIHSS score at admission, total burden of CSVD, previous stroke or transient ischemic attack history, homocysteine, fasting blood glucose, uric acid and SAA between the END group and the non-END group (all P<0.05). Multivariate logistic regression analysis showed that SAA was an independent risk factor for END (odds ratio 4.703, 95% confidence interval 2.492-8.875; P<0.001). There was a significant difference in SAA among different CSVD burden groups ( P<0.001), and SAA increased with the increase of CSVD burden score. Ordinal multivariate logistic regression analysis showed that SAA was independently correlated with the overall burden of CSVD (odds ratio 4.576, 95% confidence interval 2.542-8.239; P<0.001). Conclusion:SAA is associated with the overall burden of CSVD and END in patients with AIS.

Objective:To explore the distribution and hematological characteristics of rare thalassemia-associated mutations in Chenzhou region of Hunan Province with an aim to provide a basis for genetic counseling and effective prevention.Methods:A total of 37 370 individuals enrolled from January 2015 to December 2021 were screened by routine blood test and hemoglobin electrophoresis. The genotypes were determined with high-throughput sequencing.Results:A total of 8 455 thalassemia mutations (including 185 rare ones) were detected, which had involved 27 mutational types. Rare type α-Thalassemia --THAI and CD31 (AGG>AAG) have the typical microcytic hypochromic hematological features, whilst SEA-HPFH, CD14 (CTG>-TG), CD37 (TGG>TAG), -90(C>T), Codon 15 (G>A), IVS-Ⅰ-128 (T>G), CD86 (GCC>GC-) and Chinese Gγ+ (Aγδβ)0 had typical microcytic hypochromic and β-thalassemia-associated hematological features of elevated HbA2 or HbF. In addition, the -50(G>A)heterozygotes of β-thalassemia had normal or slightly decreased MCV and MCH without an increase in HbA2.Conclusion:Various forms of thalassemia-associated mutations have been identified in the Chenzhou region of Hunan Province. Above finding has facilitated development of preventive and control strategies for thalassemia as well as birth health programs.

Existing studies have shown that Astragalus membranaceus(AM)and its active ingredients astragalus polysaccharides,oninon,and astragalus methyl glycosides can attenuate X-ray radiation-induced injury.However,there are no studies on how isoliquiritigenin(ISL)attenuate the bystander effect of bone marrow mesenchymal stem cells(BMSCs)induced by carbon ion radiation therapy for lung cancer.This study aimed to investigate the AM-derived small molecule ISL to enhance radiotherapy sensitivity by attenuating the carbon ion radiation-induced bystander effect(RIBE)in BMSCs to elucidate its mecha-nism of action.In this study,we established a C57BL/6 mouse lung cancer transplantation tumor model in vivo and a co-culture model of A549 cells and BMSCs in vitro,and the models were successfully treated with carbon ions.In further work,we used flow cytometry,immunofluorescence,Western blot,enzyme-linked immunosorbent assay(ELISA),inhibitor,short hairpin RNA(shRNA),Cell Counting Kit-8(CCK-8),and other methods to illustrate the mechanism.In the next experiments,we found that ISL combined with carbon ion radiotherapy had a significant anti-tumor effect and protected BMSCs from radiation damage.The aim of this study was to investigate the potential of ISL in enhancing the sensitivity of lung cancer cells to radiotherapy and attenuating RIBE in both in vitro and in vivo settings.Traditional Chinese medicine combined with radiation therapy is a promising and innovative treatment for non-small cell lung cancer.These results establish a theoretical foundation for further clinical development of ISL as a potential radiosensitizer option.

Objective:To investigate the safety and effectiveness of endoscopic cold snare resection of small colorectal polyps and prophylactic hemostatic clip.Methods:A total of 260 patients diagnosed as having small colorectal polyps in Qinghai Provincial People's Hospital from January 2021 to March 2022 were randomly assigned to cold snare polypectomy (CSP) group (receiving CSP), CSP+hemostatic clip group (receiving CSP+prophylactic hemostatic clip), hot snare polypectomy (HSP) group, and HSP +hemostatic clip group (receiving HSP+prophylactic hemostatic clip). Each group had 65 cases. The treatment, incidence of bleeding, and other complications were compared.Results:There was no significant difference in the basic characteristics of patients or polyps among the four groups ( P>0.05). Immediate intraoperative bleeding occurred in 5 cases (7.69%), 4 cases (6.15%), 3 cases (4.62%), and 3 cases (4.62%) in the four groups respectively with no significant difference ( χ2=0.778, P=0.855), while only 1 delayed postoperative bleeding was observed in HSP group with no significant difference among the four groups ( χ2=3.012, P=0.390). The incidence of postoperative abdominal pain was the highest in the HSP group ( n=7, 10.77%) significantly different from those of the CSP group ( n=1, 1.54%) and the CSP+hemostatic clip group ( n=1, 1.54%) ( P<0.05). Polypectomy time of single polyp in CSP group was the shortest (2.18±1.07 min) , followed by HSP group (2.83±0.82 min), then CSP+hemostatic clip group (3.15±1.16 min), with HSP+hemostatic clip group (4.88±1.85 min) being the longest ( F=50.397, P<0.001). Conclusion:It is suggested to use CSP for small colorectal polyps. If there is no risk of bleeding or perforation during the operation, it is not necessary to use prophylactic hemostatic clips.

Obesity is an independent factor affecting the development, progression and prognosis of breast cancer. Adipokines and their receptors play an important role in the development and progression of breast cancer. Leptin is one of the important adipokines. After binding with leptin receptors, leptin not only plays an important role in metabolism, but also promotes tumor cell proliferation, migration and angiogenesis, inhibits tumor cell apoptosis and other biological effects. Besides, it is related to the outcome of neoadjuvant chemotherapy and treatment resistance. This paper reviews the possible molecular mechanism, expression characteristics, treatment and relationship with prognosis of leptin and leptin receptor in breast cancer.
