The Solomon four-group design, a critical method for improving internal validity in clinical research, can reduce bias and control the interference of Hawthorne effects and pretest sensitization on research results, which offers unique advantages in evaluating complex intervention outcomes. This paper systematically outlined the core framework and key points of statistical analysis of the Solomon four-group design, summarized its applications in clinical research at home and abroad, explored its advantages and limitations, and discussed the potential value in traditional Chinese medicine (TCM) clinical trials. It is believed that the Solomon four-group design can help distinguish between testing effects and intervention effects in TCM clinical studies, and reduce the bias in the evaluation of subjective indicators. Meanwhile, given the complexity of the Solomon four-group design and the particularity of TCM clinical research, it is proposed that future TCM clinical studies should focus on using psychological scales, know-ledge, attitude, and behavior measurements, and other similat evaluations as endpoints. It also advocates strengthening interdisciplinary collaboration to provide new methodological paths for TCM clinical research.

Abstract
Migraine is a widespread neurovascular disorder, the pathogenesis of which is closely linked to the release of calcitonin gene-related peptide(CGRP), leading to a significant impairment in patients′ quality of life. CGRP receptor antagonists exert their therapeutic effect by inhibiting the interaction between CGRP and its receptors, thereby preventing migraine attacks. Currently, several agents, including Rimegepant and Ubrogepant, have either received approval from the U. S. Food and Drug Administration or are in advanced stages of clinical trials.These drugs offer multiple advantages, such as the absence of vasoconstrictive effects, a rapid onset of action, and minimal interference with the immune system. Nevertheless, further investigation is necessary to assess their longterm safety, the potential emergence of drug resistance, and the development of individualized treatment protocols.Moreover, the integration of these novel therapies with existing treatment strategies remains a critical area for future research. This review aims to summarize recent national and international scientific advancements to establish a theoretical basis for the application of precision medicine in migraine management.

AIM: To explore the effects of preoperative anterior segment parameters on the rotational stability of Toric intraocular lens(Toric IOL).METHODS:Prospective study. A total of 41 cataract patients(54 eyes)with combined corneal regular astigmatism from March to December 2023 were included and treated with cataract phacoemulsification combined with plate loop Toric IOL implantation in the Department of Ophthalmology of the First Affiliated Hospital of Zhengzhou University. The rotation degree of Toric IOL and uncorrected distance visual acuity(UCDVA)were evaluated at 1 d, 2 wk, and 1 mo postoperatively, the corrected distance visual acuity(CDVA)was evaluated at 2 wk and 1 mo after surgery, and the decentration and tilt of the Toric IOL were assessed at 2 wk postoperatively.RESULTS:A total of 33 patients(40 eyes)were included in this study. The UCDVA(LogMAR)of 1 d, 2 wk and 1 mo postoperatively were 0.10(0.10, 0.30), 0.05(0, 0.10)and 0(0, 0.10), respectively, which was improved compared with the preoperative levels of [0.80(0.49, 1.00)](P<0.001). The CDVA(LogMAR)of 2 wk and 1 mo postoperatively were 0.05(0, 0.15)and 0(0, 0.138), respectively, which was improved compared with preoperative levels of [0.52(0.40, 0.80)](P<0.001). The residual astigmatism of 2 wk and 1 mo postoperatively were 0.625(0.25, 0.75)D and 0.50(0.25, 0.75)D, respectively, which was significantly reduced compared with preoperative astigmatism of [1.82(1.31, 2.59)D](P<0.001). The preoperative anterior segment length(ASL), and lens thickness(LT)were positively correlated with Toric IOL rotation degree at 1 d(rs=0.463, P=0.003; rs=0.340, P=0.032)and 2 wk(rs=0.520, P=0.001; rs=0.409, P=0.009)postoperatively. At 1 mo postoperatively, only ASL was positively correlated with Toric IOL rotation degree(rs=0.463, P=0.003). The results of linear regression analysis showed that preoperative ASL was a predictor of rotation degree at 1 d, 2 wk and 1 mo after surgery(F1 d=10.098, P1 d=0.003; F2 wk=16.915, P2 wk<0.001; F1 mo=10.957, P1 mo=0.002). The rotation degree of Toric IOL was positively correlated with lens decentration(rs=0.360, P=0.043).CONCLUSION:The early postoperative rotation of Toric IOL is positively correlated with ASL, and the rotation is also positively correlated with lens decentration.

Objective To construct a risk prediction model for depression in the patients with posther-petic neuralgia(PHN)based on machine learning algorithm to provide a new idea and method for accurate prediction of depressive state occurrence in clinical PHN patients.Methods The inpatients with PHN in the Second Affiliated Hospital of Army Military Medical University from June 2022 to June 2023 were selected as the study subjects and randomly divided into the training set and test set according to the ratio of 8∶2,and whether or not the depressive state occurring served as the outcome variable.Based on six machine learning al-gorithms of K-Nearest Neighbor(KNN),Decision Tree(DT),Logistic Regression(LR),Naive Bayes(NB),Random Forest(RF)and Support Vector Machine(SVM),a risk prediction model for PHN patients with complicating depressive state was constructed.The model performance was evaluated based on the area under the curve(AUC),accuracy,precision,recall rate and F1 score,and the optimal model was selected.Results A total of 275 PHN patients were included,among them 170 cases developed the depressive state,and the inci-dence rate of depressive state was 61.82%.The AUC values of KNN,DT,LR,NB,RF and SVM models were 0.574,0.589,0.760,0.742,0.591 and 0.733,respectively,among which the AUC value,accuracy,precision,recall rate and F1 score of LR model were the highest.Conclusion The risk prediction model of PHN compli-cating depressive state based on LR machine learning algorithm has the best performance,which is helpful for early clinical assessment and prevention of depressive state.

The functional role of glutamatergic (vGluT2) neurons in the pedunculopontine nucleus (PPN) in modulating motor activity remains controversial. Here, we demonstrated that the activity of vGluT2 neurons in the rostral PPN is correlated with locomotion and ipsilateral head-turning. Beyond these motor functions, we found that these rostral PPN-vGluT2 neurons remarkably respond to salient stimuli. Furthermore, we systematically traced the upstream and downstream projections of these neurons and identified two downstream projections from these neurons to the caudal pontine reticular nucleus/anterior gigantocellular reticular nucleus (PnC/GiA) and the zona incerta (ZI). Our findings indicate that the projections to the PnC/GiA inhibit movement, consistent with 'pause-and-play' behavior, whereas those to the ZI promote locomotion, and others respond to a new 'pause-switch-play' pattern. Collectively, these findings elucidate the multifaceted influence of the PPN on motor functions and provide a robust theoretical framework for understanding its physiological and potential therapeutic implications.
