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 investigate the correlation between bone mineral density(BMD)at different hip positions with muscle parameters and physical performance in middle-aged and elderly people in Kunming area.Methods 531 middle-aged and elderly volunteers were recruited from the Radiology Department of the First People's Hospital of Yunnan Province from May 2021 to April 2022.All study subjects completed the five-times-sit-to-stand test(FTSST)and hip quantitative CT(QCT)examinations.Volunteers'total hip(TH),femoral neck(FN),and intertrochanteric(IT)BMD were measured by using QCT PRO workstation and using OsiriX software to measure the area and density of their gluteus maximus muscle,gluteus medius,and minimus muscle and midthigh muscle.Divide male and female volunteers into positive and negative groups respectively based on FTSST time≥12 seconds or<12 seconds,and analyze the differences in hip BMD between the groups;Also divide male and female volunteers into three groups(50～59 years old,60～69 years old,70 years old and above)at the age of 10,and analyze the correlation between hip BMD and muscle parameters in different age and gender stratification.Control for age and BMI,and then perform partial correlation analysis on the above indicators.Results The BMD of the hip in the female FTSST positive group was lower than that in the negative group(P<0.001),while there was no statistically significant difference between the male groups(P>0.05).After adjusting for age and BMI,among males,FN BMD was positively correlated with gluteus medius and minimus muscle density in the age groups of 50～59 and 60～69(P<0.05),while TH BMD,FN BMD,and IT BMD were strongly positively correlated with gluteus medius and minimus muscle density in the age group over 70(P<0.05).For females,the correlation between hip BMD and muscle density in the age groups of 50～59 and 60～69 was weak,while BMD in all parts of the hip was not correlated with muscle density in the age group over 70(P>0.05).There was a negative correlation between TH BMD,FN BMD,and gluteus medius and minimus muscle area in the age group of 50～59 years old for males(P<0.05),while there was a significant negative correlation between TH BMD,IT BMD,and gluteus maximus area in the age group of 70 years old and above for females(P<0.05).Conclusion The BMD of various parts of the hip in the female FTSST positive group is lower than that in the negative group.The density of the gluteus medius and minimus muscle can to some extent serve as a predictive indicator of femoral neck bone strength in middle-aged and elderly men in Kunming area.

Objective : To investigate the correlation between the expression level of YTHDF1 in oral squamous cell carcinoma ( OSCC) and clinicopathologic features and its potential prognostic value． Methods : The expression of YTHDF1 in 132 OSCC tissues and 66 paracancerous tissues was detected by immunohistochemistry (IHC) ，and the expression of YTHDF1 protein in OSCC cell lines was detected by Western blot．The correlation between YTHDF1 and clinicopathological features was analyzed by chi-square test．Kaplan-Meier and Cox factors were used to analyze the factors affecting the survival time of the patients and draw the survival curves of the YTHDF1 gene to evaluate its potential clinical significance. Results : The expression of YTHDF1 in OSCC tissues was higher than that in para- cancerous tissues (P＜0. 001) ，and the expression of YTHDF1 protein increased in OSCC cell lines compared with normal oral epithelial keratinocytes (P ＜0. 001) ．The expression of YTHDF1 was correlated with the TNM stage and T stage of patients with OSCC (P＜0. 05) ，and the patients with high expression of YTHDF1 had a shorter sur- vival time compared with those with low expression (P ＜0. 001) ． Conclusion High expression of YTHDF1 may be associated with poor patient prognosis and YTHDF1 may be able to serve as a target for OSCC treatment.

Tooth extraction is a common and widely employed therapeutic procedure in oral and maxillofacial surgery.Minimally invasive tooth extraction can reduce both physical and psychological trauma to the patients,and is widely recommended as a first-line clinical treatment.But currently no guidelines or consensus has been available to provide a systematic introduction of minimally invasive tooth extraction to guide the clinical practices.To address this issue,this consensus,based on a comprehensive literature review and clinical experiences of experts,systematically summarizes the indications,target patients,and contraindications of minimally invasive tooth extraction,the overall workflow of this procedure(preoperative preparation,surgical steps,postoperative management,postoperative instructions,medications,and follow-up),and its common postoperative complications to provide a comprehensive guidance for clinical application of this technique.

Objective:To assess the value of a model based on helicobacter pylori(Hp)status and peripheral blood levels of pepsinogen Ⅰ(PGⅠ),PGⅡ,and gastrin-17(G-17)for predicting disease progression in high-risk populations for gastric cancer.Methods:Retrospective se-lection of clinical data from 126 high-risk individuals for gastric cancer who underwent PGⅠ,PGⅡ,G-17,and C14 urea breath tests and gastro-scopy tissue biopsy at Tianjin University Jinnan Hospital from January 2023 to January 2024,Based on pathological biopsy results using gast-ric cancer tissues obtained by gastroscopy,the high-risk population for gastric cancer was assigned into normal control,precancerous lesion,and early gastric cancer groups.The diagnostic efficacies of PGⅠ,PGⅡ,G-17,C14 urea breath,and other indicators in each patient group were determined,and a predictive model was constructed.Results:The HP-positivity rate(82.35％)and PGⅡ level(22.73 ng/mL)in the early gastric cancer group were higher than those in the precancerous lesion and control groups.The PGI level(51.36 ng/mL)was lower in early gastric cancer than in precancerous lesions and control tissues.The G-17 level(5.17 pmol/L)was lower in the precancerous lesion group than in the control and early gastric cancer groups(P<0.05).Combined use of PGⅠ、PGⅡ、G-17and Hp,the area under curve(AUC)can reach 0.899,a sensitivity of 94.12％,and a specificity of 95.65％,making these factors ideal diagnostic tools for gastric cancer.According to the prediction model,the threshold for precancerous lesions was 10 points,and the critical value for early cancer was 19 points.Conclu-sions:Implementation of the C14 urea breath test combined with PGⅠ,PGⅡ,and G-17 detection in high-risk populations for gastric cancer can help monitor disease progression in high-risk populations for gastric cancer.

Background::Cerebrovascular disease (CVD) ranks among the foremost factors responsible for mortality on a global scale. The mortality patterns of CVDs and temporal trends in China need to be well-illustrated and updated.Methods::We collected mortality data on patients with CVD from Chinese Center for Disease Control and Prevention’s Disease Surveillance Points (CDC-DSP) system. The mortality of CVD in 2020 was described by age, sex, residence, and region. The temporal trend from 2013 to 2019 was evaluated using joinpoint regression, and estimated rates of decline were extrapolated until 2030 using time series models.Results::In 2019, the age-standardized mortality in China (ASMRC) per 100,000 individuals was 113.2. The ASMRC for males (137.7/10 5) and rural areas (123.0/10 5) were both higher when stratified by gender and urban/rural residence. The central region had the highest mortality (126.5/10 5), the western region had a slightly lower mortality (123.5/10 5), and the eastern region had the lowest mortality (97.3/10 5). The age-specific mortality showed an accelerated upward trend from aged 55-59 years, with maximum mortality observed in individuals over 85 years of age. The age-standardized mortality of CVD decreased by 2.43% (95% confidence interval, 1.02-3.81%) annually from 2013 to 2019. Notably, the age-specific mortality of CVD increased from 2013 to 2019 for the age group of over 85 years. In 2020, both the absolute number of CVD cases and the crude mortality of CVD have increased compared to their values in 2019. The estimated total deaths due to CVD were estimated to reach 2.3 million in 2025 and 2.4 million in 2030. Conclusion::The heightened focus on the burden of CVD among males, rural areas, the central and western of China, and individuals aged 75 years and above has emerged as a pivotal determinant in further decreasing mortalities, consequently presenting novel challenges to strategies for disease prevention and control.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Background::Lymph node staging of prostate cancer (PCa) is important for planning and monitoring of treatment. 18F-prostate specific membrane antigen positron emission tomography/computerized tomography ( 18F-PSMA PET/CT) has several advantages over 68Ga-PSMA PET/CT, but its diagnostic value requires further investigation. This meta-analysis focused on establishing the diagnostic utility of 18F-PSMA PET/CT for lymph node staging in medium/high-risk PCa. Methods::We searched the EMBASE, PubMed, Cochrane library, and Web of Science databases from inception to October 1, 2022. Prostate cancer, 18F, lymph node, PSMA, and PET/CT were used as search terms and the language was limited to English. We additionally performed a manual search using the reference lists of key articles. Patients and study characteristics were extracted and the QUADAS-2 tool was employed to evaluate the quality of included studies. Sensitivity, specificity, the positive and negative likelihood ratio (PLR and NLR), diagnostic odds ratio (DOR), area under the curve (AUC), and 95% confidence interval (CI) were used to evaluate the diagnostic value of 18F-PSMA PET/CT. Stata 17 software was employed for calculation and statistical analyses. Results::A total of eight diagnostic tests including 734 individual samples and 6346 lymph nodes were included in this meta-analysis. At the patient level, the results of each consolidated summary were as follows: sensitivity of 0.57 (95% CI 0.39-0.73), specificity of 0.95 (95% CI 0.92-0.97), PLR of 11.2 (95% CI 6.6-19.0), NLR of 0.46 (95% CI 0.31-0.68), DOR of 25 (95% CI 11-54), and AUC of 0.94 (95% CI 0.92-0.96). At the lesion level, the results of each consolidated summary were as follows: sensitivity of 0.40 (95% CI 0.21-0.62), specificity of 0.99 (95% CI 0.95-1.00), PLR of 40.0 (95% CI 9.1-176.3), NLR of 0.61 (95% CI 0.42-0.87), DOR of 66 (95% CI 14-311), and AUC of 0.86 (95% CI 0.83-0.89).Conclusions::18F-PSMA PET/CT showed moderate sensitivity but high specificity in lymph node staging of medium/high-risk PCa. The diagnostic efficacy was almost equivalent to that reported for 68Ga-PSMA PET/CT. Registration::International Prospective Register of Systematic Reviews (PROSPERO), No. CRD42023391101.

Objective    To assess mid- and long-term outcomes and share our clinical method of reduction ascending aortoplasty (RAA) in adult patients undergoing aortic valve replacement (AVR). Methods    We retrospectively analyzed clinical data of 41 adult patients with aortic valve disease and ascending aortic dilatation before and after operation of RAA+AVR in Fuwai Hospital from January 2010 to July 2017. There were 28 male and 13 female patients aged 28-76 (53.34±12.06) years. Twenty-three patients received AVR+RAA using the sandwich technique (a sandwich technique group), while other 18 patients received AVR+ascending aorta wrap (a wrapping technique group). Ascending aorta diameter (AAD) was measured by echocardiography or CT scan preoperatively and postoperatively. Results    There was no perioperative death. The mean preoperative AAD in the sandwich technique group and the wrapping technique group (47.04±3.44 mm vs. 46.67±2.83 mm, P=0.709) was not statistically different. The mean postoperative AAD (35.87±3.81 mm vs. 35.50±5.67 mm, P=0.804), and the mean AAD at the end of follow-up (41.26±6.54 mm vs. 38.28±4.79 mm, P=0.113) were also not statistically different between the two groups. There were statistical differences in AAD before, after operation and at follow-up in each group. All 41 patients were followed up for 23-108 (57.07±28.60) months, with a median follow-up of 51.00 months. Compared with that before discharge, the AAD growth rate at the last follow-up was –1.50-6.78 mm/year, with a median growth rate of 0.70 mm/year, and only 3 patients had an annual growth rate of above 3 mm/year. Conclusion    Mid- and long-term outcomes of RAA in adult patients undergoing AVR with both methods are satisfying and encouraging.
