Objective: To explore the microbial correlation between oral tongue coating (TC) and gastric mucosa (GM) in patients with gastric intestinal metaplasia (GIM). Methods: The present study recruited 1360 volunteers for upper gastrointestinal cancer screening. The microbiota in TC and GM were profiled by long-read sequencing of full-length 16S rRNA gene. The microbial diversity, community structure, and linear discriminant analysis effect size (LEfSe) were analyzed by the software Visual Genomics. SparCC correlation analysis was used to construct the commensal network and the graphical display was conducted by R software. Results: The population included 44 patients with precancerous GIM, and 28 matched controls with negative rapid urease test (RUT) and non-symptomatic chronic superficial gastritis (CSG). No significant difference in diversity was observed between GIM patients and controls in TC or GM microbiota (P > 0.05). Patients had a higher percentage of 41 – 60 co-occurring operational taxonomic units (OTUs) between TC and GM than controls (34.1% vs. 25.0%) (P < 0.05). The LEfSe showed that TC Prevotella melaninogenica and three gastric Helicobacter species (i.e., Helicobacter pylori, Helicobacter pylori XZ274, and Helicobacter pylori 83) were enriched in patients with GIM. Furthermore, GIM patients with positive RUT had a lower percentage of co-occurring OTUs over 20 (P < 0.05), and lower abundances of gastric Veillonella, Pseudonocardia, and Mesorhizobium than those with negative RUT (P < 0.05). The commensal network between TC and GM was more complex in GIM patients than in controls. GIM patients with positive RUT demonstrated more bacterial correlations between TC and GM than those with negative RUT. Finally, the serum ratio of PG-I/II was negatively correlated with three gastric Helicobacter species (Helicobacter pylori, Helicobacter pylori XZ274, and Helicobacter pylori 83) in patients with negative RUT (P < 0.05), and negatively correlated with two TC species (Fusobacterium nucleatum subsp. nucleatum and Campylobacter showae) in patients with positive RUT (P < 0.05). Conclusion The development of GIM potentiated the commensal network between oral TC and GM, providing microbial evidence of the correlation between TC and the stomach.

Objective To investigate the HPV vaccination status of children aged 9-14 years, parents’ vaccine-related cognition, willingness to vaccinate children and their influencing factors. Methods From January to April 2021, the convenience sampling method was used to collect data based on the online platform and the Department of Pediatrics and Adolescent Gynecology of the Children&#39;s Hospital of Zhejiang University School of Medicine. The data were analyzed by descriptive analysis, Chi-square test, and logistic regression. Results A total of 864 questionnaires were collected, and 846 valid questionnaires were obtained after screening, with an effective rate of 97.9%. 13.57% of mothers and 3.09% of girls were vaccinated, and the vaccine awareness rate was 68.43%. 87.22% of parents were willing to bring their children for vaccination. Risk perception (OR=4.79, 95% CI: 2.22-10.35), willingness to vaccinate themselves (OR =29.01, 95% CI: 12.62-66.69), awareness of sex education (OR =3.73, 95% CI: 1.08-12.83) and whether the vaccines were free (P<0.001) were related to whether parents were willing to vaccinate their children. Conclusion Parents of children aged 9-14 have high awareness of HPV and HPV vaccine and are willing to vaccinate their children with HPV vaccine , but the vaccination rate in children is low. Disease perception, willingness to vaccinate, awareness of sex education, and whether vaccines are free are all the factors influencing parents&#39; willingness to vaccinate children.

Objective To use World Health Organization Family International Classifications (WHO-FICs) to explore the framework and approaches of development and research of guidelines of rehabilitation at levels of policies, community and services.Methods The important documents and tools of rehabilitation at international level, including United Nations Convention on the Rights of Persons with Disabilities, WHO World Report on Disability, Community-based Rehabilitation Guideline, Rehabilitation in Health Service System, and International Classification of Diseases (ICD), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHI) of WHO-FICs, had been discussed.Results The framework, classifications, diagnosis and description of diseases and functioning, coding, intervention and functioning evaluation based on ICD-11, ICF and ICHI-β-2 had been established for development and implementation of rehabilitation guidelines and Cochrane rehabilitation.Conclusion The framework and systematic approaches of ontology, classification, terminology, coding, diagnosis and description of diseases and functioning, interventions and evaluations for the development and implementation of rehabilitation guidelines had been developed.

Objective To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on upper limbs function in chronic stroke patients. Methods From March, 2016 to May, 2018, 53 patients were randomly divided into control group (n = 27) and research group (n = 26). All the patients received conventional rehabilitation, and the research group received additional intervention of TEAS, for six weeks. They were assessed with Manual Muscle Test (MMT) on upper limbs, modified Ashworth Scale (MAS), Fugl-Meyer Assessment-upper extremities (FMA-UE), Hand Motor Status Scale and modified Barthel Index (MBI) before, at the end of 6-week treatment and twelve weeks after treatment. Results There was no significant difference in all the scores between two groups at the end of 6-week treatment (t < 1.511, P > 0.05). The scores of MMT of wrist dorsal extension, FMA-UE and MBI were better in the research group than in the control group twelve weeks after end of treatment (t > 2.312, P < 0.05). Conclusion TEAS may promote the recovery of hands and upper limbs function in chronic stroke patients.
