Objective To analyze the distribution status of the end digits of standardized blood pressure measurement recordings in the clinic and the effectiveness of standardized blood pressure measurement for community hypertension screening. Methods The first visit blood pressure measurement data from the Community Health Service Center in Jing'an District, Shanghai from June 2023 to May 2024 were collected and analyzed. According to different measurement methods, the data were divided into two groups: standardized blood pressure measurement and conventional blood pressure measurement. SPSS 19.0 software was used for data analysis. The differences in the distribution balance of the end digits of blood pressure values and the detection rate of blood pressure elevation between the two different groups were analyzed. Results The frequency range of the end digits of blood pressure recorded values in the standardized pressure measurement group was 9.42% to 10.83%, and the detection rate of elevated blood pressure was 24.89%. The conventional pressure measurement group had a preference of the end digit ^"0^", and the detection rate of elevated blood pressure was only 2.12%. The results of multiple logistic regression analysis showed that gender, age, season, and different blood pressure measurement modes were all influencing factors for the detection rate of elevated blood pressure. Conclusion The standardized blood pressure measurement mode in the clinic is suitable for community hypertension screening and pressure measurement, with higher data quality than the conventional pressure measurement mode.

Nutritional support therapy is one of the extremely important treatment methods for patients in the intensive care unit. Timely and effective nutritional support regimens can improve patients' immune function, reduce complications, and optimize clinical outcomes. Energy expenditure is influenced by multiple factors, including patients' baseline characteristics (such as physical condition, gender, age) and dynamic changes in indicators (such as body temperature, nutritional support regimens, and therapeutic interventions). The currently recognized "gold standard" for accurately assessing energy metabolism in clinical practice is the indirect calorimetry system, also known as the metabolic cart. This device monitors carbon dioxide production and oxygen consumption in real time and uses specific algorithms to estimate the metabolic proportions of the three major nutrients (carbohydrates, fats, and proteins) in energy expenditure. An appropriate nutrient ratio helps maintain the balance between supply and demand in the body's nutritional metabolism. In the management of critically ill patients, the application of the metabolic cart enables personalized nutritional therapy, avoiding over- or under-supply of energy and optimizing the use of medical resources. Furthermore, with real-time, quantitative data support from the energy metabolism monitoring system, clinicians can develop more precise nutritional intervention strategies, thereby improving patient prognosis. This article provides a systematic review of the technical features of the metabolic cart and its application value in various critical care scenarios, aiming to offer a reference for indirect calorimetry in clinical practice.

OBJECTIVES: This study aimed to investigate the association between temporomandibular disorder (TMD) and insomnia using a two-sample Mendelian randomization (MR) approach. METHODS: Bidirectional MR analyses of two samples, TMD (n=377 277) and insomnia (n=375 359), were performed using genome-wide association study statistics published in the FinnGen database. Instrumental variables were first screened, and then inverse variance weighting (IVW) and MR-Egger were used as the main-effect assessment methods. Weighted median, weighted mode, and simple mode served as supplementary methods. We used IVW and MR-Egger to test for heterogeneity, as well as MR-Egger intercepts to assess the single nucleotide polymorphism (SNP) potential level of multiplicity effects. Sensitivity analyses were conducted based on leave-one-out to identify potentially influential SNPs. All analyses were conducted by using the two-sample MR R package and were considered statistically significant when P<0.05. RESULTS: MR analysis showed the presence of TMD on insomnia (OR=1.089, 95%CI: 1.017-1.166, P=0.014). Meanwhile, no effect of insomnia on TMD (OR=0.996, 95%CI: 0.964-1.029, P=0.816) was found. The sensitivity-analysis showed that no heterogeneity existed (P>0.05), and the presence of horizontal pleiotropy was not detected (P>0.05). Leave-one-out sensitivity analysis showed no single SNP, which may affect the causal relation. All findings indicated that the causal relationship between TMD and insomnia was not significantly affected by any individual SNP and that IV did not bias the results. CONCLUSIONS Results of MR analyses showed that TMD is a risk factor for insomnia, whereas insomnia is not a risk factor for TMD.

ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure （ADHF） with the traditional Chinese medicine （TCM） pattern of Qi and Yin deficiency， Yang deficiency， and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type were randomly assigned to an observation group （34 cases） and a control group （34 cases）. Both groups received conventional Western medical treatment， while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included： TCM syndrome score， TCM syndrome efficacy， New York Heart Association （NYHA） functional classification， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， six-minute walk distance （6MWD）， hypoxia-inducible factor-1 alpha （HIF-1α）， vascular endothelial growth factor A （VEGF-A）， Caspase-3， and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex， age， vital signs， or underlying diseases between the two groups. Compared with baseline， both groups exhibited significant reductions in TCM syndrome scores， NT-proBNP， and HIF-1α levels （P<0.01）， as well as significant increases in 6MWD， LVEF， VEGF-A， and Caspase-3 levels （P<0.05， P<0.01）. After treatment， the observation group showed significantly greater reductions in TCM syndrome score， NT-proBNP， HIF-1α， and Caspase-3 levels compared with the control group （P<0.05） and significantly greater increases in 6MWD， TCM syndrome efficacy， and VEGF-A levels （P<0.05）. No significant differences were observed between the groups in NYHA functional classification， LVEF， or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α， VEGF-A， and Caspase-3.

Objective:To investigate the protective effects and mechanism of exogenous milk fat globule-epidermal growth factor 8(MFG-E8) on intestinal injury and ferroptosis in mice with acute pancreatitis (AP) and its mechanism.Methods:A total of 24 male C57 BL/6 mice were randomly divided into the normal control group, AP group, AP+ MFG-E8 group (MFG-E8 group), and AP+ MFG-E8+ cilengitide group (cilengitide group), with 6 mice in each group according to the random number table. The mice of normal control group were intraperitoneally injected with 0.9% sodium chloride solution. In the AP group, MFG-E8 group, and cilengitide group, the mice were intraperitoneally injected with 8% L-arginine twice at 1-hour intervals to induce the AP model. In the MFG-E8 group, mice were intraperitoneally injected with 20 g/kg of MFG-E8 at 2 hours after L-arginine injection. In the cilengitide group, mice were intraperitoneally injected with 20 mg/kg of cilengitide at 1 hour after the L-arginine injection, and 20 g/kg of MFG-E8 1 hour later. The mice were sacrificed and blood samples and intestinal tissues were collected at 72 hours after the first L-arginine injection. Hematoxylin-eosin staining was used to evaluate intestinal tissue injury. Myeloperoxidase (MPO) immunofluorescence staining was performed to detect neutrophils in intestinal tissues.Adenosinetriphosphate (ATP) levels were examined to detect changes in mitochondrial function. Malondialdehyde (MDA) and superoxide dismutase (SOD) levels were tested to check the level of intestinal oxidative stress. Dihydroethidium (DHE) fluorescent probe was used to label the oxygen free radicals in intestinal tissues. The expression of glutathione peroxidase 4 (GSH-Px4), solute carrier family 7 member 11 (also named xCT), and ferroptosos suppressor protein-1 (FSP-1) in intestinal tissues were detected by western blotting. Indepent-samples t-test, one-way ANOVA, and Student-Newman-Keuls test were performed for statistical analysis. Results:Intestinal tissue injury and inflammatory cell infiltration in mice were induced by intraperitoneal injection of L-arginine. Compared with those of AP model group, the intestinal pathology score, MPO fluorescence quantification and DHE fluorescence density of MFG-E8 group were significantly decreased (3.93±0.57 vs. 1.73±0.74, (26.33±4.49)/field vs. (11.00±3.27)/field, (39.67±5.79)/field vs. (12.33±3.68)/field), while the contents of ATP, MDA and SOD were increased ((77.09±8.52) μmol/g vs. (119.87±6.83) μmol/g, (0.10±0.01) μmol/g vs. (0.17±0.02) μmol/g, (105.67±6.93) U/mg vs. (144.49±18.55) U/mg), and the differences were statistically significant ( t=3.33, 3.93, 5.63, 8.77, 6.54, 4.38; all P<0.05). The results of Western blotting showed that GSH-Px4, xCT, and FSP-1 in the intestinal tissue of AP mice in the MFG-E8 group were all elevated compared with those of AP group, the relative expression levels were 1.22±0.19 vs. 0.55±0.09, 1.48±0.12 vs. 0.34±0.08, and 0.48±0.08 vs. 0.04±0.03, and the differences were statistically significant ( t=5.60, 14.39, 9.53; all P<0.05). Intraperitoneal injection of integrin αVβ3 receptor inhibitor cilengitide effectively antagonized the protective effects of MFG-E8 on intestinal injury in AP mice. Compared with MFG-E8 group, the histopathological score, MPO quantification and DHE fluorescence density of cilengitide group (3.53±0.50, (27.67±6.02)/field, and (31.33±3.86)/field, respectively) all increased, the expression of ATP, MDA and SOD were inhibited ((77.41±8.51) μmol/g, (0.19±0.04) mol/g, (100.46±8.15) U/mg); and GSH-Px4, xCT and FSP-1 all decreased, with the relative expression levels of 0.59±0.11, 0.16±0.06, and 0.10±0.03, respectively, and the differences were statistically significant ( t=3.02, 3.44, 5.04, 8.70, 4.01, 4.86, 5.05, 17.47, 8.34; all P<0.05). Conclusion:MFG-E8 alleviates intestinal oxidative stress and ferroptosis by integrin αVβ3 receptor, thereby reducing intestinal injury and inflammation in AP mice.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objectives:To investigate the effect of circular RNA (circRNA) hsa_circ_0019217 on the biological function of chorionic trophoblast cell line (HTR8/SVneo) and its mechanism in the occurrence of pre-eclampsia (PE).Methods:The circRNA expression database was used to analyze the differentially expressed circRNA in placental tissues of PE women. The expression levels of hsa_circ_0019217 and miR-526b-5p were detected by reverse transcription real-time fluorescent quantitative PCR (RT-qPCR), and the subcellular localization of hsa_circ_0019217 was detected by fluorescence in situ hybridization. The proliferation, migration and invasion of trophoblast cells were detected by cell counting kit-8 (CCK-8) assay and transwell assay. Western blot and enzyme-linked immunosorbent assay (ELISA) were used to verify the effects of hsa_circ_0019217, miR-526b-5p and decorin (DCN) on matrix metalloproteinase 2 (MMP2), tissue inhibitor of metalloproteinase 2 (TIMP2), placental growth factor (PlGF) and human chorionic gonadotropin (hCG) protein expression levels. Dual luciferase reporter gene assay and RNA immunoprecipitation (RIP) assay were used to verify the interaction between hsa_circ_0019217, miR-526-5p and DCN.Results:(1) The analysis of circRNA expression database showed that the expression level of hsa_circ_0019217 was significantly increased in the placental tissues of PE women (fold change=67, P<0.05), and it was mainly located in the cytoplasm. (2) Knockdown of hsa_circ_0019217 promoted the proliferation, migration and invasion of HTR8/SVneo cells, increased the expression levels of MMP2 and PlGF, and decreased the expression levels of TIMP2 and hCG in HTR8/SVneo cells. (3) Hsa_circ_0019217 targeted adsorption of miR-526b-5p, and inhibition of miR-526b-5p reduced the proliferation, migration and invasion of HTR8/SVneo cells. The expression levels of MMP2 and PlGF in HTR8/SVneo cells were increased, and the expression levels of TIMP2 and hCG were decreased. Hsa_circ_0019217 knockdown and inhibiting miR-526b-5p could reverse the effect of hsa_circ_0019217 knockdown on promoting the proliferation, migration and invasion of HTR8/SVneo cells, and reversed the effect of hsa_circ_0019217 knockdown on the protein expression levels of MMP2, PlGF, TIMP2 and hCG. (4) miR-526b-5p targeted DCN in HTR8/SVneo cells, hsa_circ_0019217 knockdown reduced the expression level of DCN, and inhibiting miR-526b-5p increased the expression level of DCN. When hsa_circ_0019217 and miR-526b-5p were inhibited simultaneously, there was no significant change in the protein expression level of DCN. (5) Overexpression of miR-526b-5p promoted the proliferation, migration and invasion of HTR8/SVneo cells, while overexpression of DCN inhibited the proliferation, migration and invasion of HTR8/SVneo cells. Simultaneous overexpression of miR-526b-5p and DCN reversed the effects of miR-526b-5p overexpression on cell proliferation, migration and invasion. Overexpression of miR-526b-5p increased the expression levels of MMP2 and PlGF and decreased the expression levels of TIMP2 and hCG in HTR8/SVneo cells. Overexpression of DCN reduced the expression levels of MMP2 and PlGF and increased the expression levels of TIMP2 and hCG. Overexpression of miR-526b-5p and DCN reversed the effects of miR-526b-5p on the expression of these proteins. Conclusion:Hsa_circ_0019217 regulates the expression of DCN by adsorption of miR-526b-5p, thereby affecting the proliferation, migration and invasion of trophoblast cells and regulating the protein expression levels of MMP2, TIMP2, PlGF and hCG, which might be used as a target for early prevention of PE.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
