Objective To examine of Ye Tianshi's approach to managing internal wind through herbal remedies.Methods A comprehensive search was conducted for medical cases pertaining to internal wind,liver wind,dizziness,head wind,deficiency labor,liver fire,insomnia,convulsions,epilepsy,and headache within the Clinical Guidelines in Medical Cases.Statistical analysis of symptom elements,target locations of symptom elements,frequency of Chinese medicinal substances,their properties,and meridian affiliations was performed using Excel.Prescription patterns were further analyzed through association rules and high-frequency drug clustering.Results The study included a total of 167 medical cases,from which 241 symptom elements and 333 target locations were extracted.A total of 183 prescriptions were analyzed,comprising 132 medicinal substances with an overall frequency of 1309 occurrences.The five most frequently used Chinese medicines were Sheng Di Huang,Fu Shen,E Jiao,Fu Ling,and Shu Di Huang.The predominant property observed was cold,followed by warm and neutral;the most common flavor was sweet,succeeded by bitter and warm.The leading meridian affiliations identified were liver,kidney,lung,heart,and spleen.The drug association rule analysis revealed 14 items,while high-frequency drug clustering resulted in 9 distinct categories.Conclusion Ye Tianshi's therapeutic approach to internal wind emphasizes the concept of"yang transforming into internal wind."The core principles of this treatment strategy involve nourishing bodily fluids to mitigate wind,addressing excess conditions in the upper body while rectifying deficiencies in the lower body,and promoting tranquility in the liver and stomach.Additionally,the use of pungent and sweet flavors is employed to facilitate the transformation of wind,to clear the liver and dispel heat,to eliminate wind and resolve phlegm,to tonify qi and enhance defensive qi,and to clear heat in order to soothe the spirit.This methodology seeks to achieve harmony among the organs and meridians while pacifying internal wind.

Objective:To investigate the predominant types of enteroviruses and the characteristics of the VP1 gene of coxsackievirus A4 (CVA4) causing hand, foot and mouth disease (HFMD) in Yunnan Province from 2018 to 2020.Methods:Throat swab and stool samples were collected from HFMD cases and tested by real-time quantitative PCR for nucleic acid detection. The samples positive for enterovirus nucleic acids were used for viral isolation and sent to the National Center for Disease Control and Prevention. The VP1 gene of the isolated strains was sequenced and analyzed.Results:From 2018 to 2020, a total of 21 757 HFMD samples were collected, 16 457 (75.64%) of which were positive for enteroviruses. Altogether 533 strains were isolated from 4 114 positive samples that were selected for viral isolation, including 89 strains of enterovirus 71 (EVA71, 16.70%), 180 strains of coxsackievirus A16 (CVA16, 33.77%), 76 strains of CVA10 (14.26%), 118 strains of CVA6 (22.14%), 26 strains of CVA4 (4.88%) and 44 strains of other types (8.26%). HFMD occurred mainly in children under five years old with higher incidence in males than in females (1.35∶1). The incidence of HFMD reached the peak in the second and third quarters. In Yunnan Province, CVA4 mainly circulated in Qujing and Kunming, and was sporadically detected in Wenshan and Honghe. The VP1 gene was 915 bp in length. Twenty-six CVA4 strains belonged to C2 subtype, which were genetically far from the prototype strain AY421762-HighPoint. Mutations in the VP1 gene were found at multiple sites including 18, 23, 34, 102, 148, 164, 200, 262, 174, 275, 285 and 303. These strains showed 80.4%-99.0% homology in nucleotide sequence and 95.6%-99.0% in amino acid sequence. Nucleotide mutations were mostly synonymous mutations.Conclusions:CVA16, CVA6, EVA71 and CVA10 were the predominant enteroviruses causing HFMD in Yunnan Province from 2018 to 2020. The prevalence of CVA4 was also worthy of attention. CVA4 isolates in Yunnan Province belonged to C2 subtype, mainly circulating in the east and southeast of Yunnan Province and gradually becoming a cocirculating predominant strain. Long-term dynamic monitoring would be of great public health significance for improving the sensitivity of HFMD early warning.
