Objective The overall effect of mild-warm moxibustion on ovarian function in mice with premature ovarian insufficiency(POI)was observed by orthogonal design and multi-model comprehensive evaluation with different moxibustion parameters(MP).Methods The experiment was conducted using an L9(34)orthogonal array,with duration(factor A),distance(factor B),and frequency(factor C)as the three factors,each set at three levels.This arrangement resulted in mild-warm moxibustion intervention groups Ⅰ-Ⅸ.SPF female C57BL/6J mice were randomly assigned to these groups using a random number table method,including a blank and model group,with 15 mice per group.The POI model was established via continuous gavage of Tripterygium wilfordii multiglucoside(75 mg/kg)for 14 days.In accordance with the MP specified in the orthogonal table,each group received alternating mild-warm moxibustion on both sides of the"Shenshu"(BL23),or"Zhongwan"(CV12)and"Guanyuan"(CV4)acupoints every other session for 14 days.The estrous cycle disorder of the mice was monitored by vaginal smear.Serum estradiol(E2),follicle-stimulating hormone(FSH),luteinizing hormone(LH),anti-Müllerian hormone(AMH),and testosterone(T)levels were measured using an enzyme-linked immunosorbent assay.Ovarian morphology and follicle count were assessed using hematoxylin-eosin staining.The pregnancy rate,implantation count,live fetuses,and post-implantation mortality rate were evaluated via cohabitation observation.The estrous cycle disorder rate and FSH level were defined as the primary efficacy indicators,with the remaining indicators serving as secondary indicators.The effects of single indicators were analyzed through range and variance analyses.The Criteria Importance Through Intercriteria Correlation(CRITIC)method and the entropy weight method were used to determine indicator weights,which were then combined with the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)and grey relational analysis for comprehensive evaluation to identify the preference MP.Results Compared with the blank group,the model group showed an increase in the estrous cycle disorder rate,decreased serum E2 and AMH levels,increased FSH,LH,and T levels,reduced numbers of primordial,primary,secondary,and antral follicles,increased numbers of atretic follicles,decreased pregnancy rate,implantation count,and number of live fetuses,and increased post-implantation mortality(P<0.05).Compared with the model group,all intervention groups showed varying degrees of improvement in the indicators mentioned above.The orthogonal experiment,CRITIC-TOPSIS,entropy weight-TOPSIS,and grey relational analysis identifiedⅣ group(10 min duration,1 cm distance,once daily)as the preference parameter combination.This combination significantly reduced the estrous cycle disorder rate,upregulated serum E2 and AMH levels,downregulated FSH,LH,and T levels,increased the numbers of primordial,primary,and secondary follicles,decreased the number of atretic follicles,and improved the pregnancy rate,implantation count,and number of live fetuses(P<0.05).Conclusion The preferred MP for treating POI is 10 min duration,1 cm distance,and once daily,which improves ovarian function and fertility in POI mice.
