ObjectiveThis study aims to develop a prediction model for the compatibility of Chinese medicinal pairs based on Graph Convolutional Networks （GCN）， named HC-GCN. The model integrates the properties of herbs with modern pharmacological mechanisms to predict pairs with specific therapeutic effects. It serves as a demonstration by applying the model to predict and validate the efficacy of blood-activating herb pairs. MethodsThe training dataset for herb pair prediction was constructed by systematically collecting commonly used herb pairs along with their characteristic data， including Qi， flavor， meridian tropism， and target genes. Integrating traditional characteristics of herb with modern bioinformatics， we developed an efficacy-oriented herb pair compatibility prediction model （HC-GCN） using graph convolutional networks （GCN）. This model leverages machine learning to capture the complex relationships in herb pair compatibility， weighted by efficacy features. The performance of the HC-GCN model was evaluated using accuracy （ACC）， recall， precision， F1 score （F1）， and area under the ROC curve （AUC）. Its predictive effectiveness was then compared to five other machine learning models： eXtreme Gradient Boosting （XGBoost）， logistic regression （LR）， Naive Bayes， K-nearest neighbor （KNN）， and support vector machine （SVM）. ResultsUsing herb pairs with blood-activating effects as a demonstration， a prediction model was constructed based on a foundational dataset of 46 blood-activating herb pairs， incorporating their Qi， flavor， meridian tropism， and target gene characteristics. The HC-GCN model outperforms other commonly used machine learning models in key performance metrics， including ACC， recall， precision， F1 score， and AUC. Through the predictive analysis of the HC-GCN model， 60 herb pairs with blood-activating effects were successfully identified. Among of these potential herb pairs， 44 include at least one herb with blood-activating effects. ConclusionIn this study， we established an efficacy-oriented compatibility prediction model for herb pairs based on GCN by integrating the unique characteristics of traditional herbs with modern pharmacological mechanisms. This model demonstrated high predictive performance， offering a novel approach for the intelligent screening and optimization of traditional Chinese medicine prescriptions， as well as their clinical applications.

Objective:To investigate the efficacy and safety of endoscopic resection of infratemporal fossa mass and to determine the indications for surgery.Methods:A retrospective case series study was conducted, including a total of 29 patients who underwent endoscopic surgery to treat infratemporal fossa mass in the Department of Rhinology of Beijing Tongren Hospital, Capital Medical University, from April 2008 to December 2021. Ten males and 19 females were included in the study, with age of (46.5±13.7) years. Pre-and post-operative sinus CT, sinus or nasopharyngeal enhanced MRI were evaluated, respectively. The main outcome measurements were the total resection of mass and the incidence of surgery-related complications.Results:Among the 29 cases of infratemporal fossa mass, 22 were schwannomas, 3 were cysts, 2 were neurofibromas, 1 was pleomorphic adenoma and 1 was basal cell adenoma. Preoperative imaging showed well-defined lesion boundaries, and postoperative pathology confirmed the benign nature of all cases. The endoscopic transnasal approach was used in 28 patients, while the combination of the transnasal approach and the transoral approach was used in 1 patient. Complete tumor removal was achieved in all cases with a 100% resection rate. The average follow-up time was 38 months (7-168 months), and no tumor recurrence was observed.Conclusions:The Endoscopic transnasal approach is a safe and effective surgical approach for the treatment of benign tumors or masses in the infratemporal fossa.

Objective To investigate the association between the index finger and ring finger length ratio (2D ∶ 4D) and of four loci (rs6461992‚ rs6968828‚ rs7801581‚ rs17427875) polymorphism of homeobox (HOX) A11 gene among Ningxia college students. Methods Digit camera was used to collect frontal hand photos of 667 Han college students (348 males and 319 females) from Ningxia province; Image analysis software was used to mark the anatomical points and measure finger lengths of the index and ring fingers of both hands; multiplex PCR was used to detect each locus polymorphisms of HOXA11 gene; statistical software was used to compare and analyze the differences and associations of 2D ∶4D and gene polymorphisms between different genders. Results Among Ningxia Han college students‚ both left hand and right hand 2D ∶ 4D were significantly higher in females than those of in males (all P< 0. 05)‚ and there were no significant sex differences in right-left hand 2D ∶4D; the genotypes and allele frequencies of rs7801581 locus of HOXA11 gene differed significantly between genders (all P < 0. 05)‚ and none of the other locus polymorphisms showed any significant sex differences; only female left hand 2D ∶4D was significantly associated with rs6461992 locus genotype in the relationship between 2D ∶4D and HOXA11 polymorphisms (P<0. 05). Conclusion There were significant sex differences in 2D ∶ 4D among Han college students in Ningxia‚ and the rs6461992 locus polymorphism of HOXA11 gene may be associated with the formation of 2D ∶4D in females.

Objective:To investigate the iodine nutritional status of pregnant women in Hangzhou City and analyze its influencing factors, in order to provide a basis for guiding pregnant women in Hangzhou City to supplement iodine scientifically.Methods:A stratified random sampling method was used to conduct a questionnaire survey on 1 400 pregnant women in Hangzhou City from March to October 2018. Random urine samples and household salt samples from pregnant women were collected, and the levels of urine iodine and salt iodine were measured using arsenic cerium catalytic spectrophotometry and direct titration, respectively. The iodine nutritional status of pregnant women with different basic characteristics and dietary levels were analyzed and compared (Kruskal-Wallis test), and the main influencing factors affecting the urinary iodine concentration level of pregnant women were identified (the ordinal multiple classification logistic regression analysis).Results:The median urinary iodine of pregnant women was 135.00 μg/L, and the qualified iodized salt consumption rate of pregnant women was 83.36% (1 167/1 400). In terms of basic characteristics, there were statistically significant differences in the distribution level of urine iodine among pregnant women with different pregnancy frequency, delivery frequency, and natural abortion frequency ( P < 0.05). In terms of diet, the frequency of consuming milk, yogurt, meat, and whether pregnant women consumed cabbage and cauliflower showed statistically significant differences in urinary iodine distribution levels ( P < 0.05). Ordinal multiple classification logistic regression analysis showed that the urine iodine levels of pregnant women who were pregnant twice were higher than those who were pregnant ≥3 times ( OR = 1.64, P = 0.003). Pregnant women who never or occasionally consumed yogurt had lower urine iodine levels than or equal to those who consumed 2 bottles of yogurt per day ( OR = 0.53, P = 0.044). Pregnant women who never or occasionally consumed meat and those who consumed meat once a week had higher urinary iodine levels than that who consumed meat ≥2 times per week ( OR = 1.40, 1.47, P < 0.05). Conclusions:The overall iodine nutrition of pregnant women in Hangzhou City is at an deficiency level. Pregnancy experience and dietary level are influencing factors on iodine nutrition of pregnant women. It is necessary to carry out in-depth health education for pregnant women, improve the dietary structure during pregnancy, and improve the abnormal iodine nutrition of pregnant women.
