The medicinal use of Malvae Semen has a long history. In this paper， by consulting the ancient materia medica， prescription， agronomy， literature and other aspects of the classics， the name， origin， evolution of scientific name， quality， harvesting and processing， functions and indications and others of Malvae Semen were systematically sorted out and verified， so as to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shennong Bencaojing began to use Dongkuizi as the correct name， which was used in the past dynasties， and there were also aliases such as Kuicaizi， Huacai， and Kuizi. Through the original research， it can be seen that Kuicai is the mainstream original plant of Malvae Semen， that is， Malva verticillata var. crispa， the Alcea rosea and M. cathayensis are also used. In modern times， the seeds of Abutilon theophrasti have been passed off as Malvae Semen， while the seeds of M. verticillata var. crispa have rarely been used in medicine. And Abutili Semen has been another medicinal material with different efficacy since the collection of Newly Revised Materia Medica in the Tang dynasty. Since the Ming and Qing dynasties， the cultivation of Kuicai has been decreasing， while A. theophrasti is more common and easy to obtain， and Abutili Semen and Malvae Semen are similar in morphology and confused， which should be corrected. In addition， Malvae Fructus is a Mongolian customary medicinal herb， which is different from the traditional use of seeds in traditional Chinese medicine. Kuicai， as an important vegetable in history， was widely cultivated and gradually shrunk after the Song dynasty， it is now mainly produced in southern provinces. The quality evaluation of Malvae Semen is better for those with dry bodies， full grain， grayish brown color， no mud， and no impurities. The harvesting is generally in the autumn and winter. After drying， it is seeded， sieved peel and impurities， mashed， or slightly stir-fried to yellow-white color with gentle fire. It is sweet， cold and slippery in nature and taste， with the main effects of laxation， diuresis， lactation and elimination of swelling. The efficacy of Abutili Semen is clearing heat and removing toxicity， promoting diuresis and removing nebula， the efficacy is quite different from that of Malvae Semen. Based on the results of textual research， it is suggested that M. verticillata var. crispa should be used as the medicinal source of Malvae Semen in the development of famous classical formulas， the corresponding processing methods should be selected according to the requirements of drug processing in the formulas， while the raw products are recommended to be used if the processing is not specified.

Papillary thyroid microcarcinoma(PTMC),which lacks lymph node metastasis,distant metastasis,extra-thyroid invasion,high-risk subtypes,and invasion of the trachea or recurrent laryngeal nerve,may be classified as low-risk PTMC based on clinical assessment.Surgical intervention such as lobectomy or total thyroidectomy is the primary treatment modality for PTMC.This study comprised 124 patients who underwent conformal thyroidectomy and revealed that this innovative surgical approach yielded long-term oncological outcomes comparable to those who received lobectomy or total thyroidectomy.The surgical intervention may play a significant role in the comprehensive management of PTMC,while the implementation of PTMC precision medicine necessitates the utilization of genetic testing,molecular typing,and other advanced technologies to detect early-stage high-risk factors like lymph node microinvasion and integrate biology-based surgery concept for optimal outcomes.

[Objective] To identify the risk factors associated with uric acid stones, construct a nomogram model for predicting the occurrence of the disease, and evaluate its predictive performance. [Methods] A retrospective analysis was conducted on the general and clinical data of 876 patients who underwent surgical treatment for stones at the Department of Urology, the First Affiliated Hospital of Soochow University, during Jan.2020 and Dec.2022.Based on the analysis results of stone composition, the patients were divided into the uric acid stone group (n=82) and non-uric acid stone group (n=794). All patients were then randomly split into the training group (n=526) and validation group (n=350) in a ratio of 6∶4.The training group underwent LASSO regression, univariate, and multivariate logistic regression analyses to identify predictive factors associated with the occurrence of uric acid stones.Based on the factors, a nomogram model was constructed.The performance of the model was evaluated using the validation group data by comparing it with models from other research centers. [Results] LASSO regression, univariate, and multivariate logistic regression analyses revealed that cystatin C, urine pH, and stone CT values were predictive factors for uric acid stones.The area under the receiver operating characteristic curve (AUC) of the model was 0.968 for the training group and 0.956 for the validation group.Compared to other models, this model showed better predictive performance.The integrated discrimination improvement (IDI) and net reclassification index (NRI) in the training group were 0.420 0(95%CI: 0.328 2-0.511 8), P<0.001, and 0.484 2(95%CI: 0.321 3-0.647 2), P<0.001, respectively.In the validation group, the IDI and NRI were 0.405 9 (95%CI: 0.330 7-0.481 1), P<0.001, and 0.365 3 (95%CI: 0.211 6-0.519 0), P<0.001, respectively. [Conclusion] The nomogram model based on cystatin C, urine pH, and stone CT values can predict the occurrence of uric acid stones more accurately than other models, and can serve as a clinical supportive tool for the treatment and prevention of stone recurrence.

Objective To address the challenges of poor performance and lack of interpretability in existing models,the SHAP algorithm is used to develop an interpretable machine learning model that offers a novel approach to wound age estimation,Methods Based on the previous discovery of the expression of 35 wound age healing-related genes in contused skeletal muscle,the woun age estimaton model was constructed using four algorithms,namly,Multilayer Perceptron(MLP),Random Forest(RF),LightGBM(LGBM),and Support Vector Machine(SVM).The SHAP(Shapley Additive Explanation)algorithm was used to rank the importance of genetic features,eliminate redundant attributes,and optimize the model for accurate wound age estimation.the genetic features of the optimal model were analyzed using SHAP's local interpretation capabilities.Results The best results were obtained using model of MLP(area under the curve(AUC)=0.99)The wound ages were classified into four categories:4～12 h,16～24 h,28～36 h,and 40～48 h,using only 15 gene features.According to SHAP analysis,Fam210a was identified as the most relevant gene.Local analysis revealed that high expression of Fam210a contributed to an increase in the predicted probability of 4 h～12 h,while high expression of Rae1 contributed to an increase in the predicted probability of 16 h～24 h.Additionally,low expression of Tbx18 contributed to an increase in the predicted probability of 28 h～36 h,whereas high expression of Tbx18 contributed to an increase in the predicted probability of 40 h～48 h.Conclusions The combined MLP and SHAP model can be used to predict wound age.Using the SHAP interpreter can better understand the degree of contribution of feature genes to the model prediction,and lay the foundation for further in-depth study of wound age estimation.

Currently, gastrectomy+D 2 lymph node dissection has become the standard treatment for advanced gastric cancer, but the 5-year survival rate of gastric cancer patients is still less than 50%. In order to improve the prognosis of patients with advanced gastric cancer, neoadjuvant therapy has emerged. Neoadjuvant chemotherapy has been widely used in the treatment of gastric cancer. At the same time, neoadjuvant immunotherapy (NAI) represented by PD-1 inhibitors has begun to emerge in the treatment of locally advanced gastric cancer. Whether neoadjuvant therapy, especially NAI, inflicts an increased complications after radical resection of gastric cancer is still a matter of sorne concern. Therefore, this article reviews the application of neoadjuvant therapy for gastric cancer, perioperative complications and influencing factors of surgical complications.

Objective: The aging demographic landscape worldwide portends a heightened prevalence of neurodegenerative disorders. Foremost among these is Alzheimer’s disease (AD), the foremost cause of dementia in older adults. The shortage of efficacious therapies and early diagnostic indicators underscores the imperative to identify non-invasive biomarkers for early detection and disease monitoring. Recently, blood metabolites have emerged as promising candidates for AD biomarkers. Methods: Leveraging nuclear magnetic resonance (NMR) spectroscopy on plasma specimens, we conducted a cross-sectional study encompassing 35 AD patients and 35 age-matched healthy controls. Cognitive function was evaluated using the mini-mental state examination in all participants, followed by peripheral blood sample collection. We utilized univariate and multivariate analyses to perform targeted lipidomic profiling via NMR spectroscopy. Results: Our study revealed significant differences in the expression profiles of low-density lipoprotein-associated subfractions in females and high-density lipoprotein-associated subfractions in males between AD patients and healthy controls (all p<0.05). However, there was no significant metabolite overlap between males and females. Furthermore, receiver operating characteristic curve analysis demonstrated that the combination of lipid metabolites had good diagnostic values (all area under the curve>0.70; p<0.05). Conclusion Our findings suggest that the blood plasma samples using NMR hold promise in distinguishing between AD patients and healthy controls, with significant clinical implications for advancing AD diagnostic methodologies.
