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 search, evaluate and summarize the best evidence for oral fluid intake management in adult patients with urinary calculi, providing a decision-making basis for clinical nursing.Methods:Using keywords such as urolithiasis, urinary calculi, fluid intake, water intake, fluid, etc., a systematic search was conducted in relevant domestic and international databases, guideline websites, and professional association sites for evidence related to oral fluid intake management in adult urolithiasis patients. This included clinical decisions, best practices, guidelines, expert consensus, evidence summaries, systematic reviews, and recommended practices, covering the period from January 1, 2018 to June 1, 2023. Two researchers trained in evidence-based nursing independently evaluated the quality of the literature and extracted and integrated the evidence.Results:A total of 23 articles were included, comprising two clinical decisions, one best practice, four guidelines, 13 systematic reviews, and three recommended practices. Ultimately, 18 pieces of best evidence were summarized from six aspects: the importance of fluid intake, intake volume, timing of intake, the relationship between different types of fluids and the risk of urinary calculi, intake recommendations, monitoring methods, and precautions.Conclusions:This study summarizes the best evidence for oral fluid intake management in adult patients with urinary calculi, which can provide reference for clinical nursing. When applying this evidence, it is essential to fully consider clinical circumstances and patient characteristics to reduce the recurrence rate of urinary calculi.

Extracellular vesicles (EV) are highly heterogeneous nanoscale vesicles secreted by cells. They carry various bioactive molecules derived from the parent cells. EV are widely distributed in various body fluids, showing enormous potential in liquid biopsy and disease treatment. However, conventional flow cytometers face challenges in detecting single EV with a diameter smaller than 300 nm. The nano-flow cytometry (nFCM) developed based on Raleigh scattering and sheath-flow single-molecule fluorescence detection has successfully pushed the detection limit of EV to 40 nm. Through multi-parameter detection at the single-particle level, nFCM enables simultaneous analysis of particle size, particle concentration, and multiple biochemical properties of individual EV. nFCM can be applied to clinical diagnosis and therapeutics based on EV.

Objective To explore the effects of metformin on the proliferation,migration,and epithelial-mesenchy-mal transition(EMT)of human lens epithelial cells(LEC)induced by transforming growth factor-β2(TGF-β2).Methods Immortalized human LEC(HLEB-3 cells)was selected as the cell source.Human LEC with a cell fusion degree of 80％was cultured in DMEM low-glucose medium containing 10 mg·L-1 TGF-β2 for 24 hours as the control group.The cells treated with TGF-β2 and then further treated with different concentrations of metformin were used as the experimental group.After treatment,the morphological changes of cells in each group were observed under an inverted microscope.The cytotoxicity was detected by CCK-8 assay,and the cell survival rate was calculated.The expression levels of Yes-associated protein 1(YAP1),large tumor suppressor 1(LATS1),and Vimentin in cells were detected by Western blot.The mRNA ex-pression levels of YAP1,LATS1,mammalian STE20-like kinase 1(MST1),Vimentin,and E-cadherin were detected by re-al-time quantitative polymerase chain reaction.Results The cytotoxicity test of metformin showed that when the concen-tration of metformin was greater than 15 mmol·L-1,the survival rate of human LEC significantly decreased,indicating that the concentration of metformin had a significant impact on the survival of LEC.Therefore,15 mmol·L-1 was selected for subsequent experiments.Metformin significantly inhibited the proliferation of human LEC induced by TGF-β2 in a dose-dependent manner(P＜0.001).After 24 hours of treatment with 15 mmol·L-1 metformin,the relative expression levels of YAP1 and Vimentin proteins in human LEC were lower than those in the control group(both P＜0.05),while the relative expression level of LATS1 protein was higher than that in the control group(P＜0.05).After 24 hours of treatment with 15 mmol·L-1 metformin,the relative expression levels of YAP1 and Vimentin mRNA in human LEC were lower than those in the control group,while the relative expression levels of LATS1,MST1,and E-cadherin mRNA were higher than those in the control group,with statistically significant differences(all P＜0.05).Conclusion Metformin can inhibit the prolifer-ation,migration and EMT of human LEC induced by TGF-β2 in vitro,downregulate the expression of YAP1 and Vimentin mRNA,and upregulate the expression of LATS1,MST 1 and E-cadherin.The mechanism of action may be related to its ac-tivation of the Hippo signaling pathway.

Zearalenone(ZEN)is a mycotoxin that extensively contaminates food and feed,posing a significant threat to public health.However,the mechanisms behind ZEN-induced intestinal immunotoxicity remain unclear.In this study,Sprague-Dawley(SD)rats were exposed to ZEN at a dosage of 5 mg/kg/day b.w.for a duration of 14 days.The results demonstrated that ZEN exposure led to notable pathological alterations and immunosup-pression within the intestine.Furthermore,ZEN exposure caused a significant reduction in the levels of apolipoprotein E(ApoE)and liver X receptor(LXR)(P＜0.05).Conversely,it upregulated the levels of myeloid-derived suppressor cells(MDSCs)markers(P＜0.05)and decreased the presence of 27-hydroxycholesterol(27-HC)in the intestine(P＜0.05).It was observed that ApoE or LXR agonists were able to mitigate the immunosuppressive effects induced by ZEN.Additionally,a bioinformatics analysis highlighted that the downregulation of ApoE might elevate the susceptibility to colorectal,breast,and lung cancers.These find-ings underscore the crucial role of the 27-HC/LXR/ApoE axis disruption in ZEN-induced MDSCs proliferation and subsequent inhibition of T lymphocyte activation within the rat intestine.Notably,ApoE may emerge as a pivotal target linking ZEN exposure to cancer development.

Objective:To investigate the feasibility and clinical diagnostic value of rapid arterial spin labeling (ASL) imaging in brain glioma.Methods:Patients with glioma admitted to Beijing Tiantan Hospital, Capital Medical University from May 2021 to December 2022 were prospectively enrolled. All patients received MR rapid ASL (scan time: 1 min) and conventional ASL (scan time: 4 min 30 s), where the cerebral blood flow (CBF) perfusion maps were obtained. The qualitative analysis of CBF signal intensity and quantitative analysis of average CBF values from both tumor solid and edema regions were conducted by two radiologists independently. Kappa test and intraclass correlation coefficient ( ICC) were used to analyze the consistency of qualitative and quantitative results, respectively. Results:A total of 30 patients with brain glioma were included. The 2 physicians used rapid ASL to determine low perfusion, isoperfusion, and hyperperfusion in the tumor area in 1, 6, 23 cases and 0, 5, and 25 cases, respectively; and used conventional ASL to determine low perfusion, isoperfusion, and hyperperfusion in the tumor area in 0, 9, and 21 cases, respectively. The results of qualitative analysis of rapid ASL and conventional ASL were highly consistent within and between groups ( Kappa was 0.830 and 0.850 respectively). The results of quantitative analysis of rapid ASL and conventional ASL were highly consistent within and between groups ( ICC 0.940—0.994). Conclusion:Rapid ASL with shorter scanning time could be applied in assessing tissue perfusion in brain glioma and contribute to the clinical diagnosis of gliomas.

Tendon-bone healing is a complex biological process. Multiple signaling pathways are involved in tendon-bone healing， including transforming growth factor-β signaling pathway， bone morphogenetic protein signaling pathway， Wnt signaling pathway， fibroblast growth factor signaling pathway and nuclear transcription factor-κB signaling pathway. This paper summarizes the research status of traditional Chinese medicine regulating related signaling pathways to promote tendon-bone healing. It is found that a variety of traditional Chinese medicine monomers or herbal extracts （such as baicalein， icariin， total flavonoids of Drynaria fortunei， parthenolide， total saponins of Panax notoginseng， etc.） and traditional Chinese medicine compounds （such as Taohong siwu decoction， Liuwei dihuang pill， Xujin jiegu liquid， etc.） can promote bone formation， anti-inflammatory， anti-oxidation， by regulating the above signaling pathways， thereby effectively promoting tendon-bone healing.

AIM: To analyze the diagnostic value of optical coherence tomography angiography(OCTA)in evaluating the parameters of foveal avascular zone(FAZ)in early diabetic retinopathy(DR).METHODS: Retrospective study. A total of 209 cases(209 eyes)of type 2 diabetes mellitus(T2DM)with DR admitted to our hospital from June 2019 to December 2022 were selected as DR group. The DR group was divided into three groups, with 115 cases(115 eyes)in mild group, 54 cases(54 eyes)in moderate group, and 40 cases(40 eyes)in severe group according to stage. Another 100 cases(100 eyes)of T2DM patients without DR were selected as No-DR group, and 70 cases(70 eyes)of healthy people were selected as control group for physical examination at the same time, all of whom underwent OCTA examination. The DR group was enrolled according to the disease degree, one eye was randomly taken for the study if the degree in both eyes was the same, while the control group and the No-DR group were randomly selected for one eye to be included in the study. The perimeter of the foveal avascular area(PERIM), FAZ transverse diameter, FAZ vertical diameter, FAZ area, macular fovea retinal thickness(MFRT), acircularity index(AI), full layer retinal blood flow density within a range of 300 μm around the FAZ(FD-300), and changes in FAZ vascular density(VD)levels among different groups of subjects were compared. Furthermore, Pearson correlation analysis was used to determine the correlation between general data and FAZ related indicators, and receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of macular FAZ indicators for DR.RESULTS: The levels of FBG, MFRT, FAZ area, and PERIM in patients with mild, moderate, and severe DR were significantly higher than those in the No-DR group and the control group, while the levels of AI and VD were significantly lower than those in the No-DR group(all P<0.05); patients in the No-DR group, mild DR group, moderate DR group, and severe DR group had significantly higher cystatin C, FAZ transverse diameter, and FAZ vertical diameter than the control group, while FD-300 vascular density was significantly lower than the control group(all P<0.05); the MFRT was positively correlated with age(r=0.295, P=0.001); The AI and VD was negatively correlated with age(r=-0.296, -0.235, all P<0.05); the area under the curve(AUC)of MFRT, FAZ area, PERIM, AI, and VD for the diagnosis of DR were 0.745, 0.738, 0.696, 0.792, and 0.847, respectively.CONCLUSION:The structure and microcirculation of FAZ can be changed in DM patients, and the related parameters of FAZ have certain value in the diagnosis of early DR.

In this research， a comprehensive examination of historical materia medica， medical literature， medical books and contemporary literature was conducted to systematically compile and verify the naming， origin， geographical variations， quality， medicinal properties and processing of Tremolitum， and combined with the physical analysis of 15 batches of samples， with a view to providing a basis for the quality evaluation. The evidences unequivocally support Yangqishi as the rectification of name， while alternative aliases include Baishi， Shisheng， Yangjushi and Yangshi. The primary source of Tremolitum has been the silicate hornblende mineral tremolite throughout recorded history， and its accompanied minerals are mainly chlorite， talc schist， anthophyllite asbestos， etc. In ancient times， the main production area of Tremolitum was situated in the "Yaoshan Mountain" region of Jinan， Shandong province. Presently， it is primarily produced in Hubei， Henan， Shanxi， Hebei and Shandong provinces. The ancient quality evaluation of Tremolitum includes "white color"， "wolf teeth"， "cloud head and rain foot"， "heron hair"， etc. While， modern materia medica mostly evaluates its quality in terms of color， luster and texture， including the characteristics of needle bundle， grayish-white， glossy and easy to be twisted and crushed. Tremolitum is slightly warm， non-toxic， and possesses a salty taste. It is associated with the kidney meridian， known for its benefits in nourishing the fire of the gate of life， warming the kidneys and strengthening the Yang. Common processing methods include fire calcination， elutriation， and processing with wine. Additionally， there is an exclusive processing method known as the "ascending Tremolitum method". Through the X-ray diffraction（XRD） analysis， the commercially available Tremolitum is mainly composed of tremolite［Ca₂Mg₅（Si₄O₁₁）₂（OH）₂］， and the accompanied minerals are calcite and quartz， etc. Its color includes white， light gray， light green and so on， and it is weight and soft texture， irregular cross-section， with obvious fibrous texture and mostly glassy luster. Among the commercially available Tremolitum， samples with high content of tremolite are characterized by high quality features， such as "white color"， "heron hair" and "ease of tearing". Also， Tremolitum is the Fe-bearing heterogeneous species of tremolite， and the two are often symbiotic. Therefore， by the herbal textual research and the comparison of the properties and composition of Tremolitum and its similar species， it has been verified that the primary source of Tremolitum is the silicate hornblende minerals tremolite and actinolite.
