ObjectiveTo systematically evaluate the measurement content, psychometric properties and quality of evidence of patient-reported outcome measures (PROMs) for adolescents with spinal dysfunction based on International Classification of Functioning, Disability and Health-Children and Youth (ICF-CY) framework, Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) and modified GRADE approach. MethodsDatabases including CNKI, Wanfang Data, PubMed, Embase and Web of Science were systematically searched for studies assessing psychometric properties of PROMs targeting adolescents with spinal dysfunction. The methodological quality of included studies was evaluated using COSMIN Risk of Bias checklist, the psychometric properties were rated according to COSMIN criteria, and evidence quality was graded using modified GRADE approach. Item content of each PROM was coded following the ICF-CY linking rules. ResultsA total of 23 studies involving eight PROMs were included. Brace Questionnaire (BrQ), Italian Spine Youth Quality of Life Questionnaire (ISYQOL), Quality of Life Profile for Spinal Deformities (QLPSD), Spinal Appearance Questionnaire (SAQ), Scoliosis Japanese Questionnaire-27 (SJ-27) and Scoliosis Research Society-22 Revised Questionnaire (SRS-22r) were rated as grade B, while EuroQol Five-Dimension Youth Five-Level Questionnaire (EQ-5D-Y-5L) and Young Spine Questionnaire (YSQ) were rated as grade C. The eight PROMs were linked to six to 24 ICF-CY categories. BrQ covered the largest number of categories (n = 24), followed by SJ-27 (n = 19) and SRS-22r (n = 16). Except for SAQ which mainly focused on dimension of body functions and structures, all other PROMs covered both dimension of body functions and structures, and activities and participation, while BrQ, ISYQOL, SRS-22r and YSQ also covered dimension of environmental factors. Major methodological limitations included insufficient evidence for content validity, inappropriate factor-analysis approaches, incomplete reporting for test-retest reliability, and overall scarcity of evidence concerning measurement error, minimal important change (MIC) and responsiveness. ConclusionThe quality of PROMs in adolescents with spinal dysfunction varies. BrQ, ISYQOL, QLPSD, SAQ, SJ-27 and SRS-22r show application potential, yet further high-quality studies are required to supplement their psychometric evidence. EQ-5D-Y-5L and YSQ exist high-quality insufficient evidence. Selection of PROMs should comprehensively consider target population, measurement purpose, content coverage and quality of evidence. Further researches are needed to improve reporting quality.

Objective To analyze the relationship between type 2 diabetes mellitus(T2DM)and cognitive disorder in middle-aged and elderly patients with Parkinson's disease(PD),and to identify risk factors for cognitive disorder in PD patients.Methods The clinical data of patients aged≥50 years and hospitalized for PD in Xijing Hospital of Air Force Medical University from Jan.2010 to Dec.2021 were collected,including demographic characteristics,general clinical features,laboratory indicators,etc.The cognitive status was evaluated by mini-mental state examination(MMSE).A total of 281 PD patients were assigned to T2DM group or non-T2DM group,and MMSE original score,standardized score,and cognitive status were compared between the 2 groups.The 281 patients were reassigned to normal cognition group or abnormal cognition group,then multivariate logistic regression was used to analyze the risk factors of cognitive disorder in middle-aged and elderly patients with PD.Results The MMSE original score and standardized score in the T2DM group were significantly lower than those in the non-T2DM group(23[18,25]vs 24[21,27],P=0.011;-1[-3,2]vs 1[-1,3],P=0.004),and the detection rate of cognitive disorder was significantly higher than that of the non-T2DM group(53.57%[45/84]vs 33.50%[66/197],P=0.002).Multivariate logistic regression analysis showed that T2DM(odds ratio[OR]=2.452,95%confidence interval[95%CI]1.397-4.306,P=0.002),place of residence(OR=2.208,95%CI 1.261-3.868,P=0.006),and age(OR=1.054,95%CI 1.006-1.104,P=0.028)were risk factors for cognitive disorder in middle-aged and elderly patients with PD,while serum uric acid(OR=0.274,95%CI 0.098-0.768,P=0.014)was protective factor for cognitive disorder in middle-aged and elderly patients with PD.Conclusion T2DM,rural area,advanced age,and hypouricemia are independent risk factors for cognitive disorder in middle-aged and elderly patients with PD.For middle-aged and elderly PD patients with T2DM,screening for cognitive disorder should be strengthened for early prevention and intervention.

AIM To investigate the protective effects of verbascoside on D-galactose-induced liver injury in mice and its underlying mechanisms.METHODS C57BL/6J mice were randomly assigned to the normal group,the model group,the vitamin E group(100 mg/kg),and the low-dose and high-dose verbascoside groups(40,80 mg/kg),with 10 mice in each group.Simultaneous administration of medicine and subcutaneous injection of D-galactose(600 mg/kg)went on among the groups except the normal group for 8 weeks.Serum ALT,AST,ALP activities,along with TBil levels were measured using biochemical kits.Hepatic GSH,MDA concentrations,as well as SOD and GSH-Px activities were quantified.Liver pathological morphology was evaluated by HE staining,while hepatic fibrosis area was assessed using Sirius red staining.Western blot analysis determined hepatic expression of IL-6,IL-1β,TNF-ɑ,TLR4,NF-κB p65,IκBɑ and p-IKBɑ proteins.RESULTS Compared to the model group,the groups treated with vitamin E or verbascoside demonstrated significantly reduced body weight(P＜0.05,P＜0.01);increased hepatic index(P＜0.05,P＜0.01);decreased serum activities of ALT,AST and ALP alongsided reduced TBil levels(P＜0.05,P＜0.01);attenuated pathological damage of liver tissue and fibrosis severity;reduced hepatic MDA level(P＜0.05,P＜0.01);and elevated GSH level with enhanced SOD and GSH-Px activities(P＜0.05,P＜0.01).Furthermore,the high-dose verbascoside group showed significantly decreased hepatic expressions of IL-6,IL-1 β,TNF-ɑ,TLR4,NF-κB p65,and p-IKBɑ/IKBɑ proteins(P＜0.05,P＜0.01).CONCLUSION Verbascoside improves D-galactose-induced liver injury through its antioxidant activity,anti-inflammatory effects,and suppression of the TLR4/NF-κB signaling pathway.

Aim To explore the mechanism of the syn-ergistic effect of the ferroptosis inducer erastin com-bined with shikonin in promoting ferroptosis in human hypertrophic scar fibroblasts(HSFBs).Methods Hypertrophic scar tissues provided by the General Hos-pital of Ningxia Medical University were collected,and HSFBs were extracted.HSFBs were identified by HE staining and immunofluorescence.The inhibitory rates of Era and SHK on HSFBs at different concentrations were detected by CCK-8 assay,and the IC50 value was calculated.CompuSyn software was used to calculate the co-use index(CI).Control group,Erastin(Era)group,shikonin(SHK)group and Era+SHK group were set up,and the number and morphological chan-ges of cells were observed after 24 hours of interven-tion.The ability of cell migration and invasion was de-tected by scratch test and Transwell test.The changes of malondialdehyde(MDA),total iron ion and reactive oxygen species(ROS)were detected by corresponding biochemical kits.The expressions of collagen I,α-SMA and GOT1,SLC7A11,GPX4 and FTH1 were detected by Western blot.Results The IC50 value of Era and SHK of primary HSFBs was 2.22 μmol·L-1 and 3.94μmol·L-1 respectively,which was used as the single drug concentration for subsequent experiments.The CompuSyn software was employed to calculate the CI value when the two drugs were used in combination,and the concentrations corresponding to CI=0.39597(Era:1.2 μmol·L-1+SHK:1.5 μmol·L-1)were selected as subsequent combination concentrations(Because when CI was equal to 0.395 97,the concen-tration of each drug was lower than the concentration of single drug,and the inhibition rate of combined drug was greater than 50％).Compared with the monother-apy group,the number of HSFBs in the SHK+Era group was significantly reduced,cell membrane showed breakage and vesiculation,cell wrinkling became smal-ler,and cytoplasm was concentrated.The migration and invasion ability of HSFBs in the SHK+Era group were obviously weakened(P＜0.05),and the expres-sion of fibrosis-related proteins collagen Ⅰ and α-SMA was reduced(P＜0.05);the contents of MDA,total i-ron ions,and ROS in HSFBs of the SHK+Era group increased(P＜0.05),and the protein expression lev-els of SLC7A11,GOT1,GPX4,and FTH1 further de-creased(P＜0.05).Conclusions Erastin in combi-nation with shikonin can synergistically inhibit the pro-liferation,migration and fibrosis levels of HSFBs.The mechanism may be that erastin enhances the inhibition of shikotin on GOT1,increases the levels of cellular i-ron ions,ROS,and lipid peroxides,thereby promoting ferroptosis in HSFBs.

Aim To explore the effects of Kui Jie Kang(KJK)on modulating the farnesoid X receptor(FXR)pathway in the gut microbiota and bile acid metabolism in mice with ulcerative colitis(UC).Methods Mice were subjected to DSS-induced UC and randomly as-signed to the control(CON),model(MOD),and two KJK-dosed groups(KJK.H at 12.8 g·kg-1,KJK.L at 3.2 g·kg-1).Mouse body weight was recorded,and disease activity index(DAI)was scored.The his-topathological changes in colonic tissue were observed via HE staining,and the number of goblet cells and mucosal layer repair were assessed using PAS and Al-cian blue staining.Bile acid content in feces was measured using LC-MS/MS,gut microbiota composition was analyzed by 16S rRNA gene sequencing,and the expression of FXR target genes and related proteins was detected by RT-qPCR and Western blot.Results KJK significantly ameliorated colonic shortening,de-creased disease activity index in UC mice,reduced his-topathological scores,increased the number of goblet cells and mucus secretion,altered the levels of primary and secondary bile acids,and increased the relative a-bundance of beneficial bacteria such as Lactobacillus.Additionally,it significantly upregulated the expression of FXR and FGF15 mRNA and protein in colonic tissue and downregulated the expression of hepatic CYP7A1 mRNA,and the correlation analysis in this study clearly revealed a significant correlation between bile acid me-tabolism disorders and gut microbiota imbalance in UC.Conclusion KJK activates the intestinal FXR-FGF15-CYP7A1 pathway,thereby regulating bile acid metabolism and restoring gut microbiota balance,which may be key to its improvement of UC.

Coronary artery calcification often appears a variety of complex lesions,increasing coronary intervention of the difficulty of treatment,especially the severe calcification lesions,usually cannot be fully dilated,resulting in a reduced success rate of surgery,an increased rate of acute stent thrombosis and restenosis,and even a serious impact on the prognosis of patients.Intravascular lithotripsy(IVL)is increasingly used in calcified lesions.There is more and more evidence of using in stable angina pectoris and unstable angina pectoris,but its use in acute ST-segment elevation myocardial infarction is limited,and only a few cases have been reported abroad.Moreover,the consensus of Chinese experts in the diagnosis and treatment of coronary artery calcification in 2021 edition lists thrombotic lesions as contraindications of shock wave balloon.This case is the first time in China to report the use of shock wave balloon in patients with acute ST elevation myocardial infarction complicated with thrombus.In this case,the patient with acute ST elevation myocardial infarction complicated with thrombus was severely under expanded stent after stent implantation,and obtain good curative effect using shockwave balloon at selected time in hospital after intensive anticoagulant therapy.

Aim To investigate the effects of hydroxyl-safflor yellow A(HSYA)on the regenerative and re-pair functions of human umbilical cord mesenchymal stem cells(hUC-MSCs).Methods hUC-MSCs were mechanically isolated,and their morphology was ob-served.Cell surface marker expression was analyzed u-sing flow cytometry.Osteogenic differentiation was used to confirm the multipotency of the cells.The cells were treated with various concentrations of HSYA(0,100,200,400,600 μmol·L-1),and the optimal con-centration and duration of treatment were determined u-sing the CCK-8 assay.Cells were divided into four groups:control,100,200,and 400 μmol·L-1.The proliferative capacity of hUC-MSCs was assessed by EdU incorporation.Vascular endothelial growth factor(VEGF)and brain-derived neurotrophic factor(BD-NF)levels in the culture supernatant were measured u-sing enzyme-linked immunosorbent assays.Cell migra-tion ability was evaluated by Scratch assays.The ex-pression levels of VEGF,BDNF,and fibroblast growth factor 2(FGF2)were detected by Western blotting.Results The isolated cells exhibited characteristics consistent with stem cell surface markers and demon-strated osteogenic and adipogenic differentiation poten-tial.After 48 hours of treatment,no cytotoxicity was observed at concentrations of 100,200,and 400 μmol·L-1compared to the control group.HSYA signifi-cantly increased the number of EdU-positive cells and cell migration rate,with the most pronounced effect was achieved at 200 μmol·L-1(P＜0.01).VEGF and BDNF levels in the supernatant were elevated,with the highest expression observed at 200 μmol·L-1(P＜0.01).Similarly,the expression levels of BDNF,VEGF,and FGF2 were significantly upregulated in the HSYA groups,with the highest levels at 200 μmol·L-1(P＜0.01).Conclusion HSYA promotes the proliferation,migration and angiogenesis of hUC-MSCs,with an optimal concentration of 200 μmol·L-1.

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.

Aim To investigate the effect of tetrameth-ylpyrazine(TMP)on neuroinflammation after cerebral ischemia and hypoxia via mannose-binding lectin(MBL).Methods Patients diagnosed with ischaemic stroke at Shanxi Provincial People's Hospital were in-cluded in the study,and their clinicopathological data,as well as blood and urine samples,were collected with the consent of the patients and their families.Using these biological samples,differential proteins and tar-gets were identified by proteomic analysis and subse-quently verified with animal experiments.The mice were divided into the sham,dMCAO,and TMP(10,20,40 mg·kg-1)treatment groups.After seven days of drug administration,the modified neurological sever-ity score(mNSS)was used to assess the neurological function.TTC staining was used to detect the volume of cerebral infarction.Motor function was evaluated be-haviourally,and ELISA was used to detect MASP1,sC5b-9,TNF-α,IL-6,and IL-1β.Western blot was used to determine the expression of relevant proteins,such as MBL2,MASP2,and C3.Results Compared with the sham group,the dMCAO group exhibited in-creased neurological impairment,which was signifi-cantly ameliorated by TMP treatment.The expression levels of MBL2,C3 and MASP2 were elevated in the dMCAO group and were reduced following TMP treat-ment.Additionally,the dMCAO group showed elevat-ed expression of inflammatory factors IL-1 β,IL-6 and TNF-α,which were then suppressed by TMP treat-ment.Conclusion TMP inhibits the inflammatory re-sponse after ischemia and hypoxia by regulating MBL,thus attenuating brain injury.

Objective To investigate the distribution and antibiotic resistance of clinical isolates in the Traditional Chinese Medicine Hospital of Xinjiang Medical University.Methods Bacterial strains were collected from January 1,2020,to December 31,2023,and tested for antimicrobial susceptibility using automated systems and disk diffusion methods.The results were interpreted according to the breakpoints recommended in the CLSI M100.Results Over the four-year period,22 121 bacterial strains were analyzed,including Gram-positive bacteria(24.1％,5 338/22 121)and Gram-negative bacteria(75.9％,16 783/22 121).The prevalence of methicillin-resistant S.aureus(MRSA)and methicillin-resistant coagulase-negative Staphylococcus(MRCNS)was 26.4％and 68.9％,respectively.MRSA and MRCNS strains showed higher resistance rates to most antimicrobial agents compared to methicillin-susceptible strains(MSSA and MSCNS).No Staphylococcus strains were found resistant to linezolid or vancomycin.E.faecium showed higher resistance rates to most of the antimicrobial agents tested than E.faecalis.A few vancomycin-resistant strains were identified in E.faecium and limited number of linezolid-resistant strains were identified in E.faecalis.All S.pneumoniae isolates were isolated from specimens other than cerebrospinal fluid.The prevalence of penicillin-resistant S.pneumoniae(PRSP)was 9.4％.Overall,13.2％of Klebsiella isolates were resistant to imipenem and 13.1％to meropenem,while the prevalence of carbapenem-resistant strains was less than 10％in Escherichia coli or other genera of Enterobacterales.As for non-fermenting Gram-negative bacteria,P.aeruginosa was largely susceptible to most antimicrobial agents.Overall,11.8％and 10.9％of P.aeruginosa strains were resistant rates to imipenem and meropenem,respectively.However,47.1％of Acinetobacter strains were resistant to imipenem and 47.9％to meropenem,while 14.9％to 53.2％of the strains were resistant to other antimicrobial agents tested.Conclusions The clinical strains isolated in the Traditional Chinese Medicine Hospital of Xinjiang Medical University were predominantly Gram-negative bacteria.The prevalence of carbapenem-resistant strains in Klebsiella spp.was higher than that in other species of Enterobacterales.Acinetobacter spp.showed high resistance rate to carbapenems.The prevalence of methicillin-resistant strains was high in Staphylococcus.Vancomycin-resistant and linezolid-resistant strains were identified in Enterococcus spp.Infection prevention and control and stewardship of antimicrobial agents should be strengthened to contain the emergence and spread of resistant bacteria.
