Objective: To evaluate the effects of a multidisciplinary weight management intervention, so as to provide a reference for the formulation of overweight and obesity intervention measures. Methods: From April to September 2025, overweight and obese residents aged 18-60 years who participated in a weight loss competition at the Health Management Center of Beilun People's Hospital in Ningbo City were selected as study subjects. They were divided into a control group and an intervention group. The control group received conventional weight management, while the intervention group received the multidisciplinary integrated weight management in addition to the conventional weight management, for a total intervention period of 8 weeks. Weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood pressure were collected before and after the intervention through physical examinations and laboratory tests. The generalized estimating equations (GEE) method was employed to analyze the differences in indicators between the two groups before and after the intervention. Results: The control group comprised 241 participants, including 161 females (66.80%), with a mean age of (35.66±7.80) years. The intervention group consisted of 127 participants, including 86 females (67.72%), with a mean age of (36.80±7.05) years. No statistically significant differences were observed between the two groups at baseline in terms of age, gender, weight, BMI, or waist-to-hip ratio (all P>0.05). Results from the GEE analysis indicated significant interactions between group and time for weight, BMI, waist circumference, and hip circumference (all P<0.05) with greater reductions in these parameters observed in the intervention group compared to the control group before and after the intervention. Similarly, significant interactions between group and time were observed for FBG, TG, TC, and LDL-C (all P<0.05), with the intervention group demonstrating larger decreases in these markers compared to the control group. However, no statistically significant interactions between group and time were observed for waist-to-hip ratio, HDL-C, systolic blood pressure, and diastolic blood pressure (all P>0.05). Following the intervention, a weight loss exceeding 10% was achieved by 13 participants (5.39%) in the control group and 62 participants (48.82%) in the intervention group. The proportion of individuals with a weight loss exceeding 10% was significantly higher in the intervention group compared to the control group (P<0.05). Conclusion Compared to conventional weight management, multidisciplinary integrated weight management demonstrated greater efficacy in improving weight-related indicators and blood glucose, blood lipids, and enhancing weight loss outcomes among overweight and obese residents.

Objective:To investigate the effects of Longmu Anshen prescription on microglia(MG)polarization in the medial prefrontal cortex(mPFC)and anxiety behavior of chronic restraint stress(CRS)mice.Methods:Forty-eight healthy male KM mice were randomly divided into normal group,paroxetine hydrochloride group and Longmu Anshen prescription high,middle and low dose groups.From the 15th day,after 30 minutes of CRS every day,the normal group and the model were given distilled water by gavage,the paroxetine hydrochloride group was given paroxetine hydrochloride(2.6 mg/kg)by gavage,and the traditional Chinese medicine group was given Longmu Anshen prescription at high,medium and low doses(4.16,2.08,1.04 g/kg)by gavage for 21 days.The changes of anxiety behavior in mice were evaluated by light-dark boxes experiment and elevated plus maze;ELISA was used to detect IL-1β,IL-6,TNF-α and IL-10 levels;protein expression of inducible nitric oxide synthase(iNOS)and arginase-1(Arg-1)in mice mPFC tissue were detected by Western blot;mRNA expression of ionized calcium binding adaptor molecule-1(Iba-1),iNOS and Arg-1 in mice mPFC tissue were detected by RT-PCR;the protein expression of Iba-1 in mice hippocampal tissue was detected by immuno-histochemistry(IHC).Results:Compared with normal group,the residence time in the light boxes,the number of times of shuttle between the light-dark boxes,the percentage of times of entering the open arm(OE%)and the percentage of time spent in the open arm(OT%)of mice in model group were significantly reduced(P<0.01);moreover,in the mPFC tissue of the model group mice,the protein and mRNA expressions of Iba-1 and iNOS were significantly increased(P<0.01),and the levels of IL-1β,IL-6 and TNF-α were significantly increased(P<0.01),while the protein and mRNA expressions of Arg-1 were significantly decreased(P<0.01),and the level of IL-10 was significantly decreased(P<0.01).Compared with model group,the residence time in the light boxes,the number of shuttles between the light-dark boxes,the OE%and OT%of mice in the paroxetine hydrochloride group and the high and medium dose groups of Longmu Anshen prescription were significantly increased(P<0.01);the expression levels of Iba-1 and iNOS protein and mRNA in mPFC tissue were significantly decreased(P<0.05,P<0.01),and the levels of IL-1β,IL-6 and TNF-α were significantly decreased(P<0.01),while the expression levels of Arg-1 protein and mRNA were significantly increased(P<0.01).IL-10 level was significantly increased(P<0.01).Conclusion:Longmu Anshen prescription can inhibit the activation of MG in mPFC tissues of CRS mice and may reduce nerve inflammation and increase the level of anti-inflammatory cytokines by regulating the polarization phenotype of M1/M2,thereby ameliorate CRS-induced anxiety behavior.

Cuproptosis is a new type of cell death that depends on intracellular copper accumulation to trigger the aggregation of mitochondrial lipoacylated protein and the degradation of iron-sulfur cluster protein,with a different mechanism of action from autophagy,ferroptosis,pyroptosis,and necroptosis.Cuproptosis is closely association with the development of liver cancer and resistance to antitumor drugs,as well as the progression of various liver diseases such as hereditary liver diseases,nonalcoholic fatty liver disease,viral hepatitis,and liver cirrhosis.This article summarizes the mechanism of cuproptosis and its role in liver diseases,in order to provide a reference for further research and treatment of liver diseases.

Background::Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods::This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.Results::At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs. placebo, 95% CI 31%–69%) and 45% (low vs. placebo, 95% CI 26%–64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator’s Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. Conclusion::CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.Trial Registration::ClinicalTrials.gov, NCT04805411.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

The clinical data, laboratory test, and gene mutations were collected from a family with pseudohypoaldosteronism type II(PHA2). The proband, aged 1 year and 7 months, presented with hyperkalemia(6.69 mmol/L; reference range 3.5-5.3 mmol/L), blood pressure of 110/68 mmHg(normal<106/61 mmHg, 1 mmHg=0.133 kPa), blood chloride of 111.5 mmol/L(reference 99-110 mmol/L), blood HCO 3- of 17.1 mmol/L(reference 22-29 mmol/L), estimated glomerular filtration rate of 128.5 mL·min -1·(1.73 m 2) -1[>90 mL·min -1·(1.73 m 2) -1], and blood renin concentration of 0.30 μIU/mL(reference 4.2-45.6 μIU/mL). The mother and maternal grandfather also exhibited normal renal function with hyperkalemia, hypertension, hyperchloremia, metabolic acidosis, and low renin. Genetic testing revealed a heterozygous missense mutation(c.1685A>G, p. E562G) in exon 7 of the no-lysine kinase 4(WNK4) gene. Treatment with hydrochlorothiazide was effective. Literature review comparing this E562G pedigree with other WNK4 variants suggested clinical heterogeneity of WNK4 mutations. For unexplained hyperkalemia, especially with concurrent hypertension, PHA2 should be considered early for genetic screening to prevent misdiagnosis or delayed diagnosis.

Objective To explore the genetic polymorphism and mutation rate of 36 Y-STR loci in Sichuan Han population and provide basic data for their forensic applications.Methods Blood samples were collected from 307 unrelated male individuals and 367 father-son pairs in Sichuan Han population using FTA blood sampling cards.The Y41SE-v1.2 kit was used to type 36 Y-STR loci,and the population genetic parameters and mutation rates of each locus were calculated.The genetic relationship between Sichuan Han population and other ethnic populations was analyzed in combination with 19 other populations in China.Results A total of 79 mutations were observed in 36 Y-STR loci in 367 father-son pairs of Sichuan Han population,with an average mutation rate of 6.00×10-3.There were 74(93.67%)one-step mutations and 5(6.33%)multi-step mutations.A total of 383 alleles were found at 36 Y-STR loci in 307 Sichuan Han males.The number of alleles at each locus ranged from 5(0.016 29)to 56(0.182 41),GD ranged from 0.100 02(DYS645)to 0.959 99(DYS385),and 306 haplotypes were found.The HD,DC and HMP values were 0.999 973,99.67%and 0.003 284,respectively.The results of genetic distance(Fst)analysis showed that the Sichuan Han population had the closest genetic distance with the Chongqing Han population(0.000 9)and the furthest genetic distance with the Xinjiang Mongolian group(0.032 0).The MDS based on genetic distance was basically consistent with the results of cluster analysis.Conclusion The 36 Y-STR loci have high genetic polymorphism in the Sichuan Han population.The study data can provide data support for the construction of the Y-STR database in this region,and also provide basic genetic information for forensic investigation and population genetics research.

【Objective】 To compare the clinical safety and effectiveness of super-mini-percutaneous nephroscope (SMP) combined with flexible ureteroscopic lithotripsy (FURL) in oblique supine lithotomy position and FURL alone in the treatment of 2.0-3.0 cm renal calculi. 【Methods】 Clinical data of 55 patients treated during Jan.2018 and May 2021 were retrospectively analyzed, including 47 cases complicated renal calculi, and 14 cases of lower calyceal calculi with infundibulopelvic angle ≤30°. SMP combined with FURL was performed in 23 cases (combined group), and FURL alone was performed in 32 cases (FURL group). The operation time, hemoglobin reduction, postoperative hospital stay, hospitalization expenses, stone-clearance rate and complications were compared. 【Results】 All operations were successful. Compared with the FRUL group, the combined group had significantly more hemoglobin reduction [(16.30±10.17) g/L vs. (6.94±6.61) g/L], longer postoperative hospital stay [(5.35±1.61) d vs. (3.19±1.26) d], and higher hospitalization expenses [(22 481±2 234) yuan vs. (18 209±2 584) yuan] (P<0.05). However, there was no significant difference in operation time [(79.57±8.52) min vs. (79.22±3.83 min),P>0.05]. One month after surgery, CT results showed that the combined group had higher stone-clearance rate (91.30% vs. 65.63%, P=0.027). There was no difference in the complication rate (21.74% vs. 21.88%, P>0.05). One case (4.35%) in the combined group and 5 cases (15.63%) in the FURL group received retreatment (P>0.05). 【Conclusion】 SMP combined with FURL in oblique supine lithotomy position is safe and effective in the treatment of 2.0-3.0 cm renal calculi, with high stone-clearance rate and low complication rate.

Objective:To investigate the changes in structural brain network topology and microstructural damage in patients with multiple sclerosis (MS), and to analyze its correlation with cognitive function.Methods:Clinical and imaging data of 114 patients with MS (MS group) diagnosed in the First Affiliated Hospital of Chongqing Medical University from May 2021 to September 2022 were analyzed retrospectively. In addition, 71 volunteers were recruited as a healthy control group (HC group) during the same period. All subjects were performed on cognitive assessment and 3D-T 1 magnetization-prepared rapid gradient echo, 3D-fluid-attenuated inversion recovery, and diffusion kurtosis imaging (DKI) scans. GRETNA software was used to obtain network topology attributes, and global attributes included global efficiency, local efficiency, and small-world attributes [clustering coefficient(Cp), shortest path length(Lp), normalized Cp(γ), normalized Lp, and small-world index (σ)]. Local attributes included betweenness centrality (BC), degree centrality (DC), nodal clustering coefficient (NCp), nodal efficiency, nodal local efficiency (NLe) and nodal shortest path length. The DKI parameter map generated by the post-processing software was used to extract the DKI parameter values of the brain region with abnormal local topology of the brain structure network. The differences of global attributes, local attributes and DKI parameter values [kurtosis fractional anisotropy (KFA), mean kurtosis (MK), radial kurtosis (RK) and axial kurtosis (AK) values] were analyzed by independent sample t-test or Mann-Whitney U test, and corrected by false discovery rate (FDR). Spearman or Pearson correlation analysis was used to evaluate the correlation between abnormal brain structure network topology attributes and cognitive scale scores in the MS group. Results:Both the MS group and the HC group structure network showed small-world attributes, and the γ and σ values of the MS group were significantly lower than those in the HC group (FDR correction, P<0.05). Compared with the HC group, BC, DC, NCp and NLe broadly reduced in the MS group, mainly involving in bilateral frontal, temporal, precuneus, amygdala, and thalamus (FDR correction, P<0.05). After FDR correction, compared with the HC group, the KFA, MK, RK and AK values of 23 brain regions with abnormal local attributes of the network in the MS group were significantly changed in several brain regions (FDR correction, P<0.05). The correlation analysis showed, after FDR correction, the DC value of the right putamen in MS patients was positively correlated with the digit span test (DST) scores ( r=0.318 ,P=0.001). Conclusion:There are extensive changes in the structural brain network of MS patients, accompanied by varying degrees of microstructural damage, and the reduction of degree centrality in the basal ganglia putamen region is associated with cognitive impairment.

Objective:To prepare a peptide fluorescent probe based on aggregation-induced emission and to investigate its application in the detection of early caries.Methods:Eight aspartate-serine-serine (DSS) were combined with aggregation-induced emission material to prepare peptide fluorescent probes, and an artificial demineralization model was established in vitro. The samples were immersed in the peptide fluorescent probe solution for 1 min, and a fluorescence imaging system was applied to examine the tooth samples and collect images and fluorescence data. Scanning electron microscopy was also applied to observe the phenotype of the teeth, and electron microscopy was applied to detect the calcium-phosphorus ratio on the enamel surface of the teeth. Polarized light microscopy was also applied to observe the enamel area of the teeth. Results:The fluorescence intensity of demineralized teeth was clearly observed to be lower than that of normal teeth in the peptide fluorescent probe-treated area, and the difference was statistically significant ( P < 0.05). The results of scanning electron microscopy showed that the enamel surface of the demineralized group had more irregular pores, while the enamel surface of the undemineralized group was flatter with only some irregular accumulation of flakes. The results of polarized light microscopy showed that a clear birefringence could be observed in the enamel region of normal teeth, while a black area or the disappearance of the birefringence effect accompanied by a partial black dark shadow could be observed in the enamel region of demineralized teeth. Conclusions:An aggregation-induced luminescence-based peptide fluorescent probe was successfully prepared, which can precisely localize the enamel and show some application value in early caries detection.
