OBJECTIVE: To explore the pain-location interaction between pressure-sensitive points on the body surface and traditional acupoints in patients with chronic non-specific low back pain (CNLBP) under different disease courses, using Euclidean distance and multivariate statistical analysis. METHODS: A pressure-sensitive point detection was performed on 30 CNLBP patients with varying disease courses. A constant pressure was applied using an FDK20 algometer within a designated lumbar area, a total of 50 points were tested, and the tested points were numbered; the visual analogue scale (VAS) pain score was recorded simultaneously. MatlabR2022a9.12. software was used to extract the positions of pressure-sensitive points, and preprocessing and normalization of point location and VAS scores data were conducted. Under constraint conditions (VAS≥8.0 ∩ Euclidean distance to acupoint≤0.5), the proportion of pressure-sensitive points within the Euclidean distance threshold to each acupoint (PVD_acupoint) was calculated, followed by multivariate statistical analysis. RESULTS: ①Constrained analysis of PVD_acupoint showed that PVD_{Qihaishu (BL24)} and PVD_{Dachangshu (BL25)} were positively correlated with disease course (r=0.55, P<0.01). ②Factor analysis and silhouette analysis revealed that PVD_{Shenshu (BL23)} and PVD_{Dachangshu (BL25)} exhibited trends consistent with disease course progression (P>0.05), with different degree (P<0.01). CONCLUSION The PVD_acupoint value based on Euclidean distance can characterize the pressure sensitivity features of traditional acupoints associated with disease. Multivariate statistical analysis of PVD_acupoint confirms that selecting the acupoint combination of Shenshu (BL23) and Dachangshu (BL25) for CNLBP is associated with the distribution of surrounding pressure-sensitive points and the pathological characteristics of the condition.

Objective:To analyze the prevalence of chronic diseases, the level of chronic disease prevention and control literacy and its influencing factors among middle-aged and elderly residents in Wenzhou from 2020 to 2023.Methods:Based on a cross-sectional research design, 19 528 usual residents aged 45-69 were retrospectively selected with a multi-stage stratified random sampling method from the health literacy monitoring survey in Wenzhou from 2020 to 2023. The χ2 tests and trend χ2 tests were employed to analyze chronic disease prevalence rates and health literacy possession rates across different population subgroups. Binary logistic regression models were used to identify determinants of chronic disease prevention health literacy among middle-aged and elderly residents in Wenzhou. The results were standardized using data from Wenzhou′s Seventh National Population Census. Results:The numbers of middle-aged and elderly respondents was 5 528, 4 822, 4 575 and 4 603 from 2020 to 2023, respectively, and the prevalence of self-rated chronic diseases was 39.56%, 37.33%, 41.29% and 39.00%, respectively (the standardized rate was 33.49%, 33.58%, 36.43% and 35.34%, respectively) in the each year, and the rates of chronic disease prevention and control literacy was 24.76%, 27.98%, 24.44% and 28.13%, respectively (the standardized rate was 27.95%, 30.11%, 27.57%, 29.78%, respectively). The rates of chronic disease prevention and control literacy was on an upward trend in middle-aged and elderly respondents in Wenzhou from 2020 to 2023 ( χ2trend=5.997, P=0.014). From 2020 to 2023, chronic disease prevention health literacy showed a positive educational gradient, with significantly higher levels observed among more educated populations (both P<0.05). Except for 2020, the residents with household income≥30 000 yuan had a higher chronic disease prevention and control literacy than those with household income less than 30 000 yuan (both P<0.05); in 2021 and 2022, the chronic disease prevention and control literacy in the people of 45-59 years was higher than that in the individuals of 60-69 years (both P<0.05); in 2020 and 2022, the rural residents had a higher chronic disease prevention and control literacy than the urban residents, and the rates of chronic disease prevention and control literacy of employees or retirees in government institutions/doctors/teachers were higher than that in the peasants (both P<0.05); in 2023, the chronic disease prevention and control literacy of the smokers was lower than that in the non-smokers ( P=0.014). Conclusions:The prevalence of chronic diseases among the middle-aged and elderly residents in Wenzhou is relatively low, people with chronic diseases, especially those with multiple chronic diseases, have a low level of chronic disease prevention and control literacy. To prevent and control chronic diseases among them, interventions should be differentiated by the chronic disease status, occupation and household income.

Objective:To explore the impact of the interaction between alcohol consumption and overweight/obesity on the risk of hypertension.Methods:It was a cross-sectional study, and convenient sampling was used to enroll physical examination participants aged 18-60 years from the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, the Affiliated Hospital of Southwest Medical University and Luzhou People′s Hospital from June to November in 2020. All the participants were given questionnaire survey, physical examination and biochemical tests. A total of 5 000 questionnaires were distributed in the study, and 4 878 questionnaires were collected, of which 4 397 (90.14%) were valid. According to the diagnostic criteria for hypertension, the study participants were divided into hypertension group (1 128 cases) and non-hypertension group (3 269 cases), and t-test and chi-square test were used to compare the differences in gender, age, and other data between the two groups; and multivariate logistic regression analysis was used to analyze the association of alcohol consumption, overweight/obesity with the risk of hypertension and the interaction between alcohol consumption and overweight/obesity on the risk of hypertension, and relative excess risk of interaction, attributable proportion of interaction and the synergy index were used to evaluate the impact of the interaction between alcohol consumption and overweight/obesity on the risk of hypertension. Results:Among the 4 397 individuals included in the analysis, 3 116 were male and 1 281 were female, with a mean age of (42.42±8.83) years. The detection rate of hypertension was 25.7% (1 128/4 397). The risk of hypertension in overweight/obese individuals was 2.566 times ( OR=2.566, 95% CI: 2.167-3.038) higher than that of non-overweight/obese individuals, and the risk of hypertension in alcohol consumption individuals was 1.486 times ( OR=1.486, 95% CI: 1.250-1.766) higher than that of non-drinkers. The risk of hypertension in drinking+non-overweight/obesity group, non-drinking+overweight/obesity group, and drinking+overweight/obesity group was 1.468 times ( OR=1.468, 95% CI: 1.112-1.936), 2.538 times ( OR=2.538, 95% CI: 1.968-3.272), and 3.796 times ( OR=3.796, 95% CI: 2.963-4.863) higher than that of non-drinking+non-overweight/obesity group, respectively (all P<0.05). Alcohol consumption and overweight/obesity had an additive interaction effect on the risk of hypertension, and the relative excess risk of interaction, attributable proportion of interaction and the synergy index was 0.791 (95% CI: 0.158-1.424), 0.208 (95% CI: 0.049-0.368), 1.394 (95% CI: 1.030-1.888), respectively. There was no significant multiplicative interaction between alcohol consumption and overweight/obesity on the risk of hypertension ( P>0.05). Conclusions:Alcohol consumption and overweight/obesity are both associated higher risk of hypertension. In addition, there is an additive interaction between alcohol consumption and overweight/obesity on the risk of hypertension.

Occult breast cancer (OBC) refers to a type of breast cancer where no primary lesion is detected through physical examination, imaging, and pathology. This report presents a clinical case of OBC with intestinal obstruction as the initial symptom. A 67-year-old female with no underlying conditions presented to Zhuzhou Hospital Affiliated to Xiangya School of Medicine, Central South University with intestinal obstruction. Contrast-enhanced CT of the abdomen showed thickening of the lower rectum and ascending colon, suggestive of a neoplastic lesion. Chest CT showed multiple enlarged lymph nodes in the left axilla. Colonoscopy revealed only mucosal congestion, roughness, and thickening. Suspecting an intestinal tumor, laparoscopic radical resection of the rectal stenosis was performed. Postoperative pathology indicated poorly differentiated adenocarcinoma of the rectum. Immunohistochemistry showed positive expression of estrogen receptor (ER), progesterone receptor (PR), GATA-binding protein 3 (GATA3), and cytokeratin 7 (CK7), suggesting breast cancer metastasis. Breast MRI revealed multiple proliferative nodules in both breasts (breast imaging reporting and data system, BI-RADS 2). Biopsies of the right lower-inner breast, bilateral axillary, and supraclavicular lymph nodes were performed. No carcinoma was found in the right breast tissues; however, small foci of carcinoma was detected in the right axillary lymph nodes, and poorly differentiated carcinoma of suspected breast origin was found in the bilateral supraclavicular and left axillary lymph nodes. The final diagnosis was OBC with lymph node and rectal metastasis. The patient died 16 months postoperatively. OBC often lacks identifiable primary breast lesions, and gastrointestinal metastases are particularly rare. Clinical manifestations are frequently masked by symptoms of metastatic lesions, making diagnosis challenging. Clinicians should maintain a high index of suspicion. Due to rapid disease progression and multiorgan involvement, prognosis is extremely poor. Early identification of the primary lesion in OBC is crucial for improving outcomes.

Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.

Objective:To analyze the distribution of different SF3B1 genotypes in patients with myelodysplastic syndromes (MDS) and its prognostic value.Methods:Totally, 377MDS patients who were initially diagnosed in the First Affiliated Hospital of Nanjing Medical University from January 2014 to January 2022 were included in the retrospective analysis.The patients were divided into three different groups according to mutation stcote of SF3B1, including 317 patients with SF3B1 wild type (SF3B1 WT) (214 males and 103 females, 63(49, 71) years old),39 patients with SF3B1 K700E mutation(SF3B1 K700E(17 males and 22 females, 65(52, 73)years old)) and 21 patients with SF3B1 non-K700E mutation(SF3B1 non-K700E)(13 males and 8 females, 67(63, 73) years old). MDS-related 20 gene mutations were detected using targeted sequencing technology; Survival curves were constructed by the Kaplan-Meier method; Cox proportional hazards model was established to evaluate different factors at diagnosis on survival by univariate and multivariate analyses.. Results:Compared with SF3B1 non-K700E patients, SF3B1 K700E patients had a higher median absolute neutrophil count ( P=0.002) and were likely to be in the low/int-1 International Prognostic Scoring System (IPSS) categories ( P=0.023). A 20-gene targeted sequencing analysis showed that, compared with SF3B1 WT patients, SF3B1 K700E patients were associated with lower frequency of ASXL1 and U2AF1 mutations ( P=0.018 and P=0.003); while compared with SF3B1 non-K700E patients, the frequency of ASXL1 mutation was significantly lower in SF3B1 K700E cases ( P=0.029). Patients with SF3B1 K700E had better overall survival (OS) in comparison with SF3B1 WT and SF3B1 non-K700E in MDS patients ( P<0.001 and P=0.045, respectively). In comparison with SF3B1 WT patients, SF3B1 MUT patients had more favorable OS and progression-free survival (PFS) in MDS without excess blasts ( P<0.001 and P<0.001, respectively), but no significant difference was found in MDS with excess blasts ( P>0.05). Compared with SF3B1 WT patients, SF3B1 K700E patients had superior OS and PFS in the int-1 IPSS category ( P=0.010 and P=0.013, respectively). By multivariable analysis, the presence of SF3B1 K700Ewas an independent predictor of superior OS ( HR=0.461,95% CI 0.262-0.811, P=0.007). Conclusion:SF3B1 K700E and SF3B1 non-K700E patients had significantly improved OS in comparison with SF3B1 WT MDS patients. Furthermore, SF3B1 K700E patients were associated with a better OS compared with SF3B1 non-K700E MDS patients. SF3B1 mutation could not overcome the poor prognostic effect of excess blasts, which highlights the importance of the SF3B1 mutation subtype in risk assessment of MDS without excess blasts.

Objective:To investigate the status of iodine deficiency disorders in children and pregnant women in Ganzhou City, Jiangxi Province, and to provide a basis for scientific iodine supplementation and adjustment of prevention and control strategies.Methods:According to the requirements of the National Iodine Deficiency Disorders Surveillance Program (2016 Edition), iodine deficiency disorders surveillance was carried out in 18 counties (cities, districts) under the jurisdiction of Ganzhou City from 2018 to 2022. Edible salt and urine samples taken from children aged 8 to 10 and pregnant women were collected to detect salt and urine iodine levels. At the same time, B-ultrasound method was adopted to measure children's thyroid volume, and the goiter rate was calculated.Results:From 2018 to 2022, a total of 27 075 edible salt samples were collected from key populations (children aged 8 - 10 and pregnant women), with a median salt iodine of 25.00 mg/kg and a qualified iodized salt consumption rate of 96.24% (26 057/27 075). The difference in the qualified iodized salt consumption rate among key populations in different years was statistically significant (χ 2 = 29.09, P < 0.001). A total of 18 061 urine samples were collected from children, with a median urine iodine of 192.10 μg/L, there was a statistically significant difference in the urine iodine level of children between different years ( H = 82.59, P < 0.001). A total of 9 014 urine samples were collected from pregnant women, with a median urine iodine of 177.20 μg/L, there was a statistically significant difference in urine iodine level of pregnant women between different years ( H = 78.78, P < 0.001). A total of 8 621 children's thyroid glands were examined, including 34 cases of goiter, with a goiter rate of 0.39%, and the goiter rate showed a decreasing trend year by year (χ 2trend = 11.09, P < 0.001). Conclusions:From 2018 to 2022, the iodine nutrition of children and pregnant women in Ganzhou City is at an appropriate level, the consumption rate of qualified iodized salt (> 90%) and the children's goiter rate (< 5%) met the national iodine deficiency disorders elimination standards. Ganzhou City continues to maintain the status of eliminating iodine deficiency disorders.

Objective To study the trends of lung cancer mortality among adult residents in Macheng City, Hubei Province from 1984 to 2018． Methods Mortality data was extracted from Macheng City disease surveillance points (DSPs) system and China Demographic Yearbook. The age-period-cohort (APC) model and Intrinsic Estimator algorithm were used to estimate the age effect, period effect and cohort effect of lung cancer mortality. Results The age effect coefficient of lung cancer mortality increased with age from 20 to 74 years old. The mortality risk of the 70-74 group was 42.62 times that of the 20-24 group. The period effect coefficient of lung cancer mortality also continued to rise with time. The cohort effect coefficient was parabolic, and residents born in 1939-1943 had the highest coefficient (1.298 4). Conclusion The risk of lung cancer death of adult residents in Macheng City significantly increased with the year and the rapid development of socio-economics.
