Objective:To construct the clinical practice pathway for narrative medicine in traditional Chinese medicine(TCM),with a view to providing clinical practice guidelines for narrative medicine in TCM for frontline practitioners.Methods:Using the realistic literature review and the Nominal Group Technique(NGT),the paper systematically sorted out the practices of humanistic care in ancient Chinese medical books and famous medical cases,as well as constructed the first draft of the clinical practice pathway and details for narrative medicine in TCM.Subsequently,experts from multiple fields were invited to demonstrate by using the NGT.After in-depth discussion and collective voting,various operational modules,and their detailed rules and supporting tools were determined,thus completing the construction of the entire practical pathway.Results:A complete set of clinical practice pathways for narrative medicine in TCM had been established.It encompassed six core modules,including"start of diagnosis and treatment","communication of disease conditions","diagnosis and explanation","joint decision-making","end of diagnosis and treatment",and"reflection and summary".Besides,detailed operating rules and supporting tools were also provided.Conclusion:The clinical practice pathway for narrative medicine in TCM integrates the humanistic spirit of TCM,the core concepts of narrative medicine,and the communication skills of psychology,providing medical workers with standardized,procedural,and operationally flexible practice guidance,which helps both doctors and patients to better communicate,empathize,and make joint decisions throughout the entire process of diagnosis and treatment.

Objective:To examine the potential of combining the blood urea nitrogen(BUN)/albumin(ALB)ratio(BAR)with soluble growth stimulation expressed gene 2(sST2)as an early warning indicator for myocardial injury in elderly patients with sepsis in the emergency intensive care unit(EICU).Methods:The clinical data of elderly patients with sepsis admitted to the EICU of the Emergency Medicine Department at Harrison International Peace Hospital of Hebei Medical University from August 2018 to August 2022 were prospectively analyzed.The patients were divided into two groups based on the presence or absence of myocardial injury: the myocardial injury group and the non-myocardial injury group.The general clinical data and laboratory indexes of the two groups were compared, and the BAR was calculated.The correlation between BAR and myocardial injury in elderly patients with sepsis was analyzed.Binary Logistic regression analysis was used to identify the risk factors for myocardial injury in elderly patients with sepsis in the EICU.MedCalc software was employed to determine the early warning value of the combined sST2 and BAR for myocardial injury in elderly patients with sepsis in the EICU.Results:A total of 165 cases were analyzed, with 106 cases(64.24%)showing myocardial injury.It was found that elderly sepsis patients with lung and abdominal infection were more likely to experience myocardial injury( P<0.05 for all).In comparison to the group without myocardial injury, the levels of inflammatory markers such as white blood cell count(WBC), neutrophil to lymphocyte ratio(NLR), lactic acid, and procalcitonin(PCT), as well as combined markers BAR and sST2, were higher in elderly sepsis patients with myocardial injury upon admission.Correlation analysis results revealed significant positive correlations between BAR and lactic acid, PCT, and C-reactive protein(CRP)within 24 hours of admission to EICU in elderly sepsis patients with myocardial injury.Among these correlations, the strongest was observed between BAR and PCT( r=0.417, P<0.001).Additionally, BAR exhibited a positive correlation with acute physiology and chronic health evaluation scoring system(APACHEⅡ)scores( r=0.241, P=0.002).Furthermore, BAR showed positive correlations with myocardial injury markers sST2 and cTnI( r=0.327, 0.307, P<0.05 for all).Logistic regression analysis revealed that septic shock( OR=2.406, P=0.008), decreased left ventricular ejection fraction(EF)( OR=0.939, P=0.015), BAR( OR=2.205, P=0.044), lactic acid( OR=1.137, P=0.014), and sST2 elevation( OR=1.016, P=0.020)were identified as independent risk factors for predicting myocardial injury in elderly patients with sepsis.The results of ROC analysis indicated that BAR had a high early warning value for the occurrence of myocardial injury in elderly patients with EICU sepsis[area under curve(AUC)0.651, P<0.05], with an optimal cut-off value of 0.32(sensitivity 77.4%, specificity 60.2%).Furthermore, the combined detection of BAR and sST2 demonstrated a higher early warning value for the occurrence of myocardial injury in elderly patients with sepsis(AUC 0.697, P<0.05).The mortality rate of patients with myocardial injury below a cut-off value of 0.32 was 36.00%(9/25), while the mortality rate of patients with myocardial injury equal to or above 0.32 was 66.67%(54/81).The difference between the two groups was statistically significant( χ2=8.624, P=0.003). Conclusions:Both BAR and sST2 are considered independent risk factors for myocardial injury in elderly patients with sepsis.The combined detection of BAR and sST2 provides a more accurate prediction for the occurrence of myocardial injury in these patients.

OBJECTIVE: To explore the laboratory phenotype and molecular pathogenesis in a Chinese pedigree affected with Hereditary coagulation factor Ⅻ (FⅫ) deficiency. METHODS: A male proband admitted to Ningbo No.2 Hospital on July 17, 2021 due to chronic gastritis and members of his pedigree (7 individuals from three generations) were selected as the study subjects. Prothrombin time (PT), activated partial thromboplastin time (APTT), FⅧ activity (FⅧ: C), FⅨ activity (FⅨ: C), FⅪ activity (FⅪ: C), FⅫ activity (FⅫ: C), and FⅫ antigen (FⅫ: Ag) were determined. All of the exons, exon-intronic boundaries, as well as the 5'- and 3'-untranslated regions of the F12 gene were subjected to Sanger sequencing. Candidate variants were verified by cloning sequencing. The effect of candidate variants on the protein function was analyzed by bioinformatics software. RESULTS: The proband, a 47-year-old male, had significantly prolonged APTT (180.0 s) and decreased FⅫ:C and FⅫ:Ag levels (< 1%). His father, mother, brother and two sons also showed certain degrees of reduction. Genetic testing revealed that the proband has harbored compound heterozygous variants of the F12 gene, namely c.1092_1093insC (p.Lys365Glnfs*69) in exon 10 and c.1792_1796delGTCTA (p.Val579Hisfs*32) in exon 14. His mother and elder son were heterozygous for the c.1092_1093ins variant, whilst his father, brother, and younger son were heterozygous for the c.1792_1796delGTCTA variant. Analysis of the promoter region of exon 1 also showed that the proband and both sons had harbored a 46T/T polymorphism, whilst other family members were 46C/T. Bioinformatic analysis suggested that the p.Val579 is a highly conserved site. Protein model analysis showed that, with the p.Val579Hisfs*32 variant, a benzene ring was added and the hydrogen bond of surrounding amino acids was changed. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.1792_1796delGTCTA was classified as a pathogenic variant (PVS1+PM2_Supporting+PM4). CONCLUSION The c.1092_1093insC (p.Lys365Glnfs*69) and c.1792_1796delGTCTA (p.Val579Hisfs*32) compound heterozygous variants of the F12 gene probably underlay the decreased FXII levels in this pedigree. Above finding has also enriched the mutational spectrum for FⅫ deficiency.

Objective To analyze the correlation between the prevalence of chronic non-communicable diseases (NCDs) and fall incidence among the elderly in urban and rural areas in Chongqing, and to provide evidence for targeted intervention. Methods In 2019, a questionnaire survey was conducted among the elderly aged 65 and over in four districts and counties using multistage stratified cluster random sampling. The difference of NCDs prevalence and fall incidence was compared by Chi-square test. The correlation between NCDs and fall incidence was analyzed by multivariate logistic regression. Results A total of 806 and 801 elderly people aged 65 and above in urban and rural areas，respectively, were investigated The fall incidence among the elderly in rural areas (12.98%) was higher than that in urban areas (7.94%) (χ2=10.916, P=0.001). The multivariable logistic regression analysis showed that the prevalence of heart disease (OR=2.988, 95%CI:1.544-5.785), osteoporosis (OR=2.696, 95%CI:1.527-4.760) and vestibular dysfunction or deafness (OR=3.180, 95%CI:1.142-8.861) was associated with fall incidence among urban elderly people. Factors including need for care (OR=2.315，95%CI：1.130-4.744), diabetes (OR=3.067，95%CI:1.634-5.756), osteoporosis (OR=1.972, 95%CI:1.210-3.214), and arthritis (OR=2.975, 95%CI:1.901-4.657) were associated with fall incidence among rural elderly people. Conclusion The fall incidence among the elderly in rural areas is higher than that in urban areas in Chongqing. The prevalence of NCD is high among the elderly. Timely treatment of NCDs should be provided to reduce fall incidence among the elderly.

Tinosporae Radix， as a traditional Chinese medicinal herb， is the dried root tuber of Tinospora sagittata or T. capillipes. It was first recorded in the Compendium of Materia Medica Supplement in the Qing Dynasty and included in the previous edition of the Chinese Pharmacopoeia.

Abstract: Objective To investigate the clinical types of children's tinea capitis and the distribution of fungal pathogens in Wuhan from 2011 to 2020, and to provide scientific basis for the prevention, diagnosis and treatment of children's tinea capitis. Methods Laboratory data of children with tinea capitis in outpatient and inpatient department of dermatology in Wuhan No.1 Hospital from January 2011 to December 2020 were collected. A total of 542 cases of pediatric tinea capitis were included, with 239 male cases and 303 female cases. Microscopic examination of fungi and culture identification were performed on the affected skin lesions of the children. Chi-square test was used to analyze the differences in pathogen spectrum of children with different age groups and clinical type. Results Among the pediatric tinea capitis patients, the age group with the highest prevalence was preschool children（3 to <7 years old), accounting for 48.52%（263/542). The top three pathogenic fungi were Trichophytes violaceum（49.26%, 267/542), Microsporum canis（31.55%, 171/542) and Trichophyton mentagrophytes （9.96%, 54/542). Trichophyton violaceum was the main pathogen in all ages, followed by Microsporum canis. The infection rate of Microsporum canis in children over 7 years old was lower than that in children under 7 years old, and the infection rate of Trichophyton rubrum in infants was higher than that in other ages. The distribution of Trichophytes violaceum, Trichophyton mentagrophytes, Nannizzia gypseum and Microsporum ferrugineum was uniform in all age groups. Trichophytes violaceum and Trichophyton tousurans mainly caused black-dot ringworm, Microsporum canis mainly caused tinea alba, Trichophyton mentagrophytes,Nannizzia gypseum and Trichophytonrubrum mainly caused kerion. Except for Microsporum ferrugineum, the composition ratios of other fungi species showed statistically significant differences among different clinical types of tinea capitis（P<0.05). Conclusions Preschool children are the most commonly affected age group by pediatric tinea capitis, and black-dot ringworm caused by Trichophytes violaceum is the main clinical type. Analysis of the high-riskage group, pathogenic fungi and clinical types of tinea capitis in children can enhance the understanding of its epidemiological characteristics, which is helpful for early diagnosis and targeted standardized treatment of pediatric tinea capitis.

Objective To investigate the current situation of animal injury among children in Chongqing, and to provide a scientific basis for relevant departments to formulate and implement strategies and measures to prevent and control animal injury to children. Methods According to the method of multi-stage stratified cluster sampling, 14,056 children in grades 4-12 in four districts of Chongqing were selected as the investigation subjects, and the occurrence of animal injuries in the past 6 months was investigated. Results The incidence of animal injury among school children in Chongqing was 0.35% and the incidence of person-time was 0.36%. The incidence rate in males (0.48%) was higher than that in females (0.31%). The incidence rate in urban children (0.43%) was higher than that in rural children (0.30%). The incidence of animal injury was the lowest in nuclear families (0.25%), and the highest in single-parent families (0.82%). There were statistically significant differences in the incidence of animal injuries in children among different fathers' occupational types, family types and parents' parenting styles (P<0.05).  The main place of child animal injury was home (57.14%). Recreational activities were the main cause of animal injury (51.02%). The main injuries were lower limbs (42.86%), upper limbs (24.49%) and head (10.20%). Conclusion The prevention and control of children's animal injury in Chongqing should focus on boys and families. It is suggested to take targeted and comprehensive interventions to prevent animal injuries in children.
