Objective: To investigate the environmental contamination of norovirus in nurseries and primary/secondary schools, so as to provide a scientific basis for effective prevention and control measures. Methods: A total of 483 external environmental samples were collected from 34 cluster outbreaks of norovirus gastroenteritis in kindergartens and primary/secondary schools in Linhai City from 2021 to 2024. Pathogen detection was conducted using a rapid nucleic acid extraction kit and realtime fluorescence RT-PCR, and the results were analyzed using the χ2 test or Fishers exact test. Results: Among the collected external environmental samples, the total positive rate of surface contamination was 13.66%. The positive rates in kindergartens and primary/secondary schools were 12.20% and 15.82%, respectively. In kindergartens, the five surfaces with the highest detection rates were desks/chairs (23.33%), toilet stool troughs (20.69%), urinal troughs (12.00%), washbasins/sinks (11.11%), and toilet mops (9.38%). In primary/secondary schools, the top five were toilet stool troughs (38.30%), urinal troughs (23.53%), toilet door handles (13.04%), toilet mops (12.50%), and drinking cups (11.11%). The difference in positive detection rates among different external environments in primary/secondary schools was statistically significant (Fishers exact probability test, P<0.01). The positive detection rate in sanitary toilets was higher than that in classroom environments (χ2=17.38), while the positive detection rate in classroom environments of kindergartens was higher than that in primary/secondary schools (χ2=5.42)(P<0.05). Conclusions Norovirus exhibits a high contamination rate in nurseries and schools, particularly in restroom areas. Strengthening sanitation and disinfection in highrisk environments, and improving hygiene awareness among children and staff, are essential for the effective prevent and control of norovirus.

Objective:To evaluate the quality of psychological distress assessment tools for cancer patients and provide evidence for clinical nurses in selecting appropriate instruments.Methods:A systematic literature search was conducted in China National Knowledge Infrastructure, VIP, Wanfang Data, China Biology Medicine disc, Embase, Cochrane Library, Medline, Web of Science, and PubMed from database inception to May 27, 2024, to identify studies on psychological distress assessment tools for cancer patients. Two reviewers independently screened the literature and extracted data based on inclusion and exclusion criteria. The quality of the included tools was evaluated using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guideline, and the quality grading was made using a modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.Results:A total of 25 articles involving 21 assessment tools were included. None of the tools reported measurement error, responsiveness, or hypothesis testing. Among them, 3 instruments: Chinese version of the Cancer Distress Scales for Adolescent and Young Adults (CDS-AYA-C), Chinese version of the Memorial Anxiety Scale for Prostate Cancer (MAX-PC), and the Chinese version of the Short Demoralization Scale (DS-Ⅱ-C) were given grade A recommendations. The remaining 18 tools received grade B recommendations.Conclusions:The CDS-AYA-C, MAX-PC, and DS-Ⅱ-C demonstrated relatively balanced measurement properties and can be temporarily recommended for assessing psychological distress in cancer patients. However, further validation of their methodological quality and psychometric properties is needed. It is also recommended to develop culturally adapted psychological distress assessment tools for cancer patients in China.

BACKGROUND:In recent years,human pluripotent stem cell derived kidney organoids and rodent models of diabetic kidney disease have also made some progress.However,because the pathogenesis of diabetic kidney disease is affected by environmental factors and genetic factors,the pathogenesis is complex,and the clinical treatment for diabetic kidney disease patients needs to vary from person to person.Therefore,more flexible and integrated approaches need to be developed,leading to the discovery of strong preclinical evidence to support more targeted interventions in patients with diabetic kidney disease.OBJECTIVE:To reviewthe research progress of diabetic kidney disease model from the aspects of diabetic kidney disease animal model,two-dimensional cell culture simulation diabetic kidney disease model,and three-dimensional organoid diabetic kidney disease model,to provide clues and ideas for further research.METHODS:China National Knowledge Network and PubMed databases were searched with"diabetes,diabetic nephropathy,diabetic kidney diseases,diabetic nephropathy models,diabetic nephropathy animal models,organoids,diabetic and organoids,diabetic and kidney organoids,kidney organoids,diabetic nephropathy cell models,diabetic nephropathy syndrome combined animal models"as Chinese and English search terms.Totally 101 articles were finally included for review and analysis.RESULTS AND CONCLUSION:Both in vivo and in vitro models of diabetic kidney disease are powerful tools to further study the pathogenesis of diabetic kidney disease.The interactions between multiple systems can be observed in animal models.Two-dimensional cell culture is easy to operate and low cost.The emerging kidney organoids fill the gap between two-dimensional and global levels,without species differences,and simulate the complexity of human kidney to a certain extent.With the continuous development of organoid technology,kidney organoids are expected to provide a new perspective for exploring the pathogenesis,pathophysiology,and drug screening of diabetic kidney disease.

AIM To investigate the repair effects of tauroursodeoxycholic acid(TUDCA)combined with bone marrow mesenchymal stem cells(BMSCs)transplantation on spinal cord injury(SCI)in rats.METHODS The rats were randomly divided into the sham operation group,the model group,the TUDCA group,the BMSCs transplantation group and the combination therapy of TUDCA and BMSCs transplantation group,with the SCI rat model established by Allen's method.The next day after modeling,the rats of TUDCA and combination therapy groups were given 200 mg/kg TUDCA by gavage.On the 3rd day after modeling,rats in BMSCs transplantation group and combination therapy group were injected with 1 mL tuned bone marrow BMSCs(the 3rd generation,1× 106/mL)via tail vein.Rats in the sham operation group and the model group were given gastric perfusion of normal saline and injection of 1 mL PBS through tail vein.On the 3rd,7th and 14th day after modeling,the rats had their motor function of hind limbs observed and BBB score determined.After the corresponding drug administration,the rats had their movement track of hind limbs recorded by footprint experiment;their the protein expressions of IL-6,IL-10,Arg-1,PI3K and Akt in spinal cord tissue detected by Western blot;their pathological changes of spinal cord tissue observed by HE staining and Nissl staining;and their expressions of MAP2,GAP43 and GFAP detected by immunofluorescence staining.RESULTS Compared with the model group,the groups intervened with TUDCA,or BMSCs transplantation,or combination therapy shared improved hind limb function and spinal cord histomorphology(P＜0.05);increased fluorescence intensity of MAP2 and GAP43,and protein expressions of IL-10,Arg-1,p-PI3K and p-Akt(P＜0.05);decreased fluorescence intensity of GFAP and IL-6 protein expressions(P＜0.05);among which the combination therapy group took the lead(P＜0.05).CONCLUSION The combination therapy of TUDCA and BMSCs transplantation may restore the function of the rat model of SCI by reducing inflammatory reaction,alleviating secondary injury,and promoting axon and myelin regeneration via PI3K/Akt signaling pathway.

OBJECTIVE: To explore the efficacy and safety of Juan Bi Pill (JBP) in treatment of active rheumatoid arthritis (RA). METHODS: From February 2017 to May 2018, 115 participants from 4 centers were randomly divided into JBP group (57 cases) and placebo group (58 cases) in a 1:1 ratio using a random number table method. Participants received a dose of JBP (4 g, twice a day, orally) combined with methotrexate (MTX, 10 mg per week) or placebo (4 g, twice a day, orally) combined with MTX for 12 weeks. Participants were required with follow-up visits at 24 and 48 weeks, attending 7 assessment visits. Participants were undergo disease activity assessment 7 times (at baseline and 2, 4, 8, 12, 24, 48 weeks) and safety assessments 6 times (at baseline and 4, 8, 12, 24, 48 weeks). The primary endpoint was 28-joint Disease Activity Score (DAS28-ESR and DAS28-CRP). The secondary endpoints included American College of Rheumatology (ACR) criteria for 20% and 50% improvement (ACR20/50), Health Assessment Questionnaire Disability Index (HAQ-DI), clinical disease activity index (CDAI), visual analog scale (VAS), Short Form-36 (SF-36) score, Medial Outcomes Study (MOS) sleep scale score, serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), tender joint count, swollen joint count, and morning stiffness. The adverse reactions were observed during the treatment. RESULTS: After 12 weeks of treatment, DAS28-ESR and DAS28-CRP scores in both groups were lower than before treatment (both P<0.01), while the remission rate of DAS28-ESR and DAS28-CRP and low disease activity of JBP group were higher than those in the placebo group (both P<0.01). JBP demonstrated better efficacy on ACR20 and ACR50 compliance rate at 12 and 48 weeks comparing to placebo (all P<0.05). The CDAI and HAQ-DI score, pain VAS and global VAS change of RA patients and physicians, the serum ESR and CRP levels, and the number of tenderness and swelling joints were lower than before treatment at 4, 8, 12, 24, 48 weeks in both groups (P<0.05 or P<0.01), while the reduction of above indices in the JBP group was more obvious than those in the placebo group at 12 weeks (ESR and CRP, both P<0.05) or at 12 and 48 weeks (all P<0.01). There was no difference in adverse reactions between the 2 groups during treatment (P=0.75). CONCLUSION JBP combined with MTX could effectively reduce disease activity in patients with RA in active stage, reduce the symptoms of arthritis, and improve the quality of life, while ensuring safety, reliability, and fewer adverse effects.
