Objective:To investigate dietary patterns of individuals aged ≥50 in Shanghai and analyze their association with frailty.Methods:Using data from the third wave of the Study on Global Ageing and Adult Health in Shanghai conducted between 2018 and 2019. We collected the frequency and average intake of food by the food frequency questionnaire. Factor analysis was used to extract dietary patterns, and a frailty index was constructed using the ratio of the cumulative total score of health deficits to 35 health-related variables considered. We used an ordinal multinomial logistic regression model to analyze the association between dietary patterns and frailty.Results:A total of 3 274 participants aged (67.9±9.2) years were included in the study, including 1 971 (60.2%) men and 1 303 (39.8%) women. We extracted four dietary patterns: high-protein-nuts pattern, potato-bean-vegetable-fruit pattern, poultry-meat pattern, and high-oil-salt pattern. After adjusting for confounding factors, the logistic regression analysis showed that compared with the high-oil-salt pattern, the high-protein-nuts pattern was negatively associated with the risk of higher frailty ( OR=0.743, 95% CI: 0.580-0.951). We did not find an association between dietary patterns and frailty between the different gender groups. In the age group 50-64, the high-protein-nuts and potato-bean-vegetable-fruit patterns were negatively correlated with a higher degree of frailty than the high-oil-salt pattern. In the low-level physical activity group, the high-protein-nuts pattern was negatively correlated with a higher degree of frailty than the high-oil-salt pattern ( OR=0.509, 95% CI: 0.361-0.720). However, we found no significant effect of the high-protein nuts pattern, potato-bean-vegetable-fruit pattern, and poultry-meat pattern on the risk of higher frailty compared to the high-oil-salt pattern in the moderate to high level of physical activity group. Conclusions:Compared to the high-oil-salt pattern, dietary patterns with a higher intake of high-protein nuts, potatoes, legumes, and fruits and vegetables might be associated with a lower risk of higher frailty in residents aged 50-64 years of age than with a high oil and salt pattern. At the same time, it may have a more significant protective effect in people with lower physical activity levels. It is suggested that a diet rich in high-protein foods, nuts, potatoes, beans, vegetables, and fruits may help reduce and delay the risk of frailty.

Objective:To understand the association between vitamin D level and grip strength in people aged ≥50 years in Shanghai.Methods:Data were obtained from the WHO's Study on Global Ageing and Adult Health in Shanghai during 2018-2019. Logistic regression model was used to analyze the association between vitamin D level and grip strength, and a stratified analysis was conducted for different gender, age and dairy product intake groups. Restricted cubic spline was used to evaluate the dose-response association between vitamin D level and low grip strength.Results:A total of 4 391 participants were included in the study, including 2 054 men (46.8%), with an average age of (67.02±8.81) years. And 1 421 individuals (32.4%) had low grip strength; 1 533 individuals (34.9%) had vitamin D deficiency, and 401 individuals (9.1%) had vitamin D deficiency. After adjusted for confounding factors, the logistic regression results analysis showed that individuals with vitamin D deficiency had a higher risk for low grip strength ( OR=1.41, 95% CI: 1.09-1.83). In men, after adjusting for confounding factors, vitamin D deficiency was positively associated with the risk for low grip strength ( OR=1.67, 95% CI: 1.12-2.50), but there was no significant association between vitamin D level and grip strength in women ( OR=1.30, 95% CI: 0.97-1.74). In age group 60-69 years and ≥80 years, there was significant association between vitamin D deficiency and low grip strength after adjusting for confounding factors ( OR=1.57, 95% CI: 1.05-2.35; OR=2.40, 95% CI: 1.08-5.31). In people who had daily intake of dairy product <250 ml, there was positive association between vitamin D deficiency and low grip strength, but there was no significant association in people who had daily dairy product ≥250 ml after adjusting for confounding factors. The restrictive cubic spline demonstrated that risk of low grip strength might decreased with the increase of vitamin D levels, however, the difference was not significant ( P>0.05). Conclusions:This study demonstrated that there is association between vitamin D level and grip strength. People with vitamin D deficiency have higher risk for low grip strength.

For Perihilar cholangiocarcinoma (pCCA), surgical resection is the only effective way to cure this disease. However, it has high postoperative mortality and high recurrence rate. Domestic and foreign scholars have constructed statistics-based evaluation methods to predict patients′ postoperative survival and complications, such as nomogram, scoring system and other prognostic models. Based on these methods, clinicians can better select patients who can benefit from surgery and choose the optimal? treatment for more severe patients. Through the adoption of other treatments or some ways to ameliorate some preoperative condition, to improve the patient′s mortality and survival. This article reviews the prognostic risk factors and prognostic models of pCCA in order to provide a reference for clinicians to predict the prognosis about the surgery.

Objective:To establish and validate reference intervals of serum vitamin K for healthy children in China.Methods:A cross-sectional study was conducted from January 2020 to May 2023, involving 807 healthy children aged 0 to 14 years, selected by stratified random sampling based on the population distribution of children in eastern, central, western, and northeastern China. Sample collection was carried out in 16 hospitals across 12 provinces, autonomous regions, and municipalities. Basic information of the children was collected using a standardized self-design questionnaire. Serum levels of vitamin K 1 and vitamin K 2 (menaquinone-4 (MK-4), menaquinone-7 (MK-7)) were measured using liquid chromatography-tandem mass spectrometry. The reference intervals was established by direct approach. The children were divided into different groups by age. Inter-group comparisons were conducted using the Kruskal-Wallis non-parametric test, and the reference intervals ( P2.5- P97.5) were determined using non-parametric methods. Screening 40 healthy children for small sample validation based on age groups within the reference range(25 from eastern, 10 from central, and 5 from western regions). Results:The age of the 807 children was 5.00 (2.00, 9.81) years, and 495 (61.3%) were males and 312 (38.7%) females. Reference intervals were established for 795 children, of whom 303 children were aged 1 month to 3 years and 492 were aged 4 to 14 years. The reference intervals for serum vitamin K 1 were 0.09-4.54 μg/L for children aged 1 month to 3 years, and 0.10-1.73 μg/L for 4-14 years. For MK-7, the intervals were 0.07-1.42 μg/L for 1 month to 3 years and 0.19-2.03 μg/L for 4-14 years. The reference intervals for MK-4 in children aged 1 month to 14 years were 0-0.42 μg/L. The measured values of serum vitamin K 1, MK-4, and MK-7 in the validation samples did not exceed the reference limit in more than 2 samples. Conclusion:Reference intervals for vitamin K 1, MK-4, and MK-7 in healthy children aged 1 month to 14 years have been established and validated, and can be used to assess vitamin K nutritional status in children.

Gallbladder cancer is a common malignant tumor of the biliary tract, characterized by a stealthy onset, high invasiveness, and poor prognosis. The 5-year survival rate of gallbladder cancer patients is only 5%-20%. Currently, radical surgery remains the only potentially curative method for gallbladder cancer. Historically, gallbladder cancer was once considered a contraindication for laparoscopic surgery. In recent years, with the improvement of preoperative diagnosis level of gallbladder cancer, progress in surgical techniques and laparoscopic equipment, an increasing number of clinicians have explored and recognized the effectiveness of laparoscopic surgery for the treatment of gallbladder cancer. This review summarizes the latest advances in laparoscopic surgery for gallbladder cancer.

Objectives:Aimed to establish a rapid, high-throughput, automated method for determining the creatine kinase (CK-MM) isoform levels.Methods:Magnetic beads labeled with anti-CK-MM antibodies were combined with alkaline phosphatase-based chemiluminescence detection. Clinical and diagnostic performance validation of the assay was determined by analysis of 998 and 75 dried blood spot samples from healthy newborns and Duchenne muscular dystrophy (DMD) patients, respectively, and the CK activity was also determined. The blank and detection limits, cross-reactivity, recovery rate of the method, intra-and inter-assay coefficient, and the hook effect were evaluated.Results:Blank and detection limits were 17.4 and 39.3 ng/ml, respectively. Cross-reactivity toward CK-MB and CK-BB isoforms was 0.2% and 0.02%, respectively. Intra-and inter-assay coefficients of variation were<1%. Mean recovery was 100.32%, with no hook effect in CK-MM levels<50 000 ng/ml. Overall, the mean CK-MM concentrations in newborns and DMD patients were (27.05±0.97) and (3 720±300.5) ng/ml, respectively. A significant positive correlation between the dried blood spot detected CK-MM levels and total CK enzyme activity, evaluated in corresponding serum samples from the 75 DMD patients, was observed ( r=0.91, P<0.001), ?which is in good agreement with the clinical. Conclusions:An assay for rapid quantitative determination of CK-MM that meets clinical newborn screening requirements was established. It had a good value for application.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons (MNs) with large unmet medical needs. Multiple pathological mechanisms are considered to contribute to the progression of ALS, including neuronal oxidative stress and mitochondrial dysfunction. Honokiol (HNK) has been reported to exert therapeutic effects in several neurologic disease models including ischemia stroke, Alzheimer's disease and Parkinson's disease. Here we found that honokiol also exhibited protective effects in ALS disease models both in vitro and in vivo. Honokiol improved the viability of NSC-34 motor neuron-like cells that expressed the mutant G93A SOD1 proteins (SOD1-G93A cells for short). Mechanistical studies revealed that honokiol alleviated cellular oxidative stress by enhancing glutathione (GSH) synthesis and activating the nuclear factor erythroid 2-related factor 2 (NRF2)-antioxidant response element (ARE) pathway. Also, honokiol improved both mitochondrial function and morphology via fine-tuning mitochondrial dynamics in SOD1-G93A cells. Importantly, honokiol extended the lifespan of the SOD1-G93A transgenic mice and improved the motor function. The improvement of antioxidant capacity and mitochondrial function was further confirmed in the spinal cord and gastrocnemius muscle in mice. Overall, honokiol showed promising preclinical potential as a multiple target drug for ALS treatment.
