In order to promote the development of hair transplantation, particularly the establishment of standards, the Hair Transplantation Expert Group of Plastic and Aesthetic National Medical Quality Control Center invited experts in the field of hair transplantation across China and formed a draft of the Expert Consensus on Standard Terminology for Hair Transplantation based on the collation of relevant literature and monographs. By combining Delphi methodology and consensus meetings, the expert group conducted several rounds of consultations on issues such as follicular unit anatomy, harvesting, dissection, and implantation, ultimately presenting 54 terminologies. This consensus considers the original Chinese and English meanings as well as the professional characteristics of terms used in hair transplantation, highlights the unique features and advantages of hair transplantation, and preserves its essence while promoting innovation, with the hope of providing valuable reference for clinical researchers engaged in hair transplantation both domestically and internationally, and better facilitating the standardization and advancement of the field.

ABSTRACT OBJECTIVE To explore the correlation between HPLC fingerprint and analgesic efficacy of Zhejiang vinegar Corydalis Rhizoma, and to screen out the material basis of analgesic effect of Zhejiang vinegar Corydalis Rhizoma.METHODS Established HPLC fingerprint of Zhejiang vinegar Corydalis Rhizoma and dysmenorrhea model in rats. The weight loss rate, writhing response, serum malondialdehyde(MDA), estradiol(E2), prostaglandin E2(PGE2) and prostaglandin F2α(PGF2α) levels were used as the evaluation indexes of analgesic efficacy. Combined with chemometrics, the main active components of analgesic effect of Zhejiang vinegar Corydalis Rhizoma and the important components with great contribution to the content were screened.RESULTS The fingerprints of different batches of Zhejiang vinegar Corydalis Rhizoma were established, and nine components were identified; compared with the blank group, the weight loss rate, writhing reaction, MDA, E2 and PGF2α levels in the model group were significantly increased. Compared with the model group, the above indexs in the administration group was decreased. Compared with the blank group, the PGE2 level in the model group was significantly decreased. Compared with the model group, the PGE2 level in the administration group was significantly increased. The vinegar Corydalis Rhizoma produced in Zhejiang had a good analgesic effect, and the main active components of its analgesic effect were protopine, palmatine hydrochloride, and dehydrocorydaline. The important components with greater contribution to the content were tetrahydropalmatine, protopine, palmatine hydrochloride and stylopine.CONCLUSION The efficacy of Zhejiang vinegar Corydalis Rhizoma is the result of the combined action of multiple components, and each component has a strong correlation with the pharmacodynamic indexes. This study provides a reference for the screening of analgesic material basis of Zhejiang vinegar Corydalis Rhizoma.
