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.

Objective: To explore the core features of trait aggression in children and adolescents, so as to provide a theoretical basis for behavioral interventions targeting the central psychological characteristics of aggression in children and adolescents. Methods: From March to May 2020, a simple random convenience sampling method was employed to recruit 39 165 students from grades 4 to 12 in Sichuan, Chongqing, Guizhou, and Shandong. Data were collected via online questionnaires, with all participants completing the Chinese Version of the Aggression Questionnaire. Psychometric network analysis was utilized for data processing. Results: Trait aggression among Chinese children and adolescents was at a moderately low level. The core nodes of the network structure included physical aggression [if someone intentionally causes trouble for me, I will hit them severely (AGG6); if someone hits me, I will retaliate (AGG11)] and self aggression [When I am very irritable, I think of hurting myself (AGG5); when I am in a bad mood, I engage in behaviors that harm my health, such as overeating (AGG25)]. Across grade levels, core nodes primarily originated from the anger dimension [When I m angry, I feel like a powder magazine that could explode at any moment (AGG13); I can t control my temper (AGG18); I am prone to getting angry when I see things that are not pleasing to the eye (AGG23); I will get angry for no reason (AGG27)]. Except for grades 7 and 9, core nodes in other grades included the verbal aggression dimension [I am prone to arguments with people (AGG22)]. Before grade 8, core nodes incorporated the self aggression dimension (AGG 5, AGG 25); after grade 8, core nodes included the physical aggression dimension [AGG 6, AGG 11, I fight slightly more than others (AGG16), and if people around me make things difficult for me to a certain extent, I will fight with them (AGG26)]. No statistically significant differences were found in the trait aggression network structures across grades, genders, or within gender comparisons of different grades. Conclusion These findings broaden our understanding of aggression in children and adolescents, suggesting that behavioral interventions can effectively reduce aggressive behaviors in this population.

In cases where a tracheal injury exceeds half the length of the adult trachea or one-third of the length of the child trachea, it becomes difficult to perform end-to-end anastomosis after tracheal resection due to excessive tension at the anastomosis site. In such cases, tracheal replacement therapy is required. Advances in tissue engineering technology have led to the development of tissue engineering tracheal substitutes, which have promising applications. Hydrogels, which are highly hydrated and possess a good three-dimensional network structure, biocompatibility, low immunogenicity, biodegradability, and modifiability, have had wide applications in the field of tissue engineering. This article provides a review of the characteristics, advantages, disadvantages, and effects of various hydrogels commonly used in tissue engineering trachea in recent years. Additionally, the article discusses and offers prospects for the future application of hydrogels in the field of tissue engineering trachea.

Objective To analyze the clinical features and surgical treatment strategies of T4a thyroid cancer.Methods We retrospectively analyzed patients with thyroid cancer treated in the Department of Head and Neck Surgery of Sichuan Cancer Hospital from January 2004 to May 2021.A total of 303 cases were included and statistically analyzed for pathological type,invaded organs,surgical approach,survival time,and overall survival rate.The postoperative survival curves of the patients were analyzed using the Kaplan Meier method.Results Of the 303 patients enrolled,53 patients were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 98.4％(246/250),97.0％(224/231)and 90.2％(92/102),respectively.Of the 94 patients with recurrent laryngeal nerve invasion only,13 were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 100％(81/81),98.7％(77/78)and 97.4％(38/39),respectively.There were 151 patients with invasion of recurrent laryngeal nerve and tracheal/laryngeal/esophageal nerve,31 of them were lost to follow-up,and the 1-year,3-year and 5-year overall survival rates were 96.7％(116/120),95.3％(101/106)and 82.2％(37/45),respectively.According to the survival curve analysis,the group with recurrent laryngeal nerve invasion only had an advantage in overall survival time over the group with recurrent laryngeal nerve and tracheal/laryngeal/esophageal invasion.Conclusion Surgical resection is supposed to be preferred for T4a thyroid cancer if there is a chance of surgery.A reasonable surgical strategy,radical surgery while preserving the vital tissues and organs,and one-stage repair and reconstruction can bring patients a better quality of life and prognosis.

Objective To analyze the current research application status and hotspots of nanoparticles in the treatment of non-small cell lung cancer (NSCLC) and predict the future development trend. Methods The Web of Science database was searched for literatures on nanoparticles use in the treatment of NSCLC from inception to November 2022. CiteSpace, VOSviewer and literature measurement analysis online platform (https://bibliometric.com/) were used for the visual analysis of the number of documents, source journals, authors, organizations, countries and keywords. Results A total of 742 English literatures were included. The results showed that the number of published literatures increased year by year from 2011 and reached the peak in 2020. Researches on nanoparticles and NSCLC treatment were mainly concentrated in China, the United States, India and Japan. China is a major research country in this field, but it lacked cooperation with other countries and related institutions. Among numerous research institutions, the Chinese Academy of Sciences was the authoritative and backbone force in this research field, with the number of published literatures ranking first and the research achievements outstanding. The keyword analysis found that "poly lactic-co-glycolic acid nanoparticles (PLGA NPs)" and "photothermal therapy" had become the latest breakout words since 2018. Moreover, the occurrence frequency of related keywords such as "drug delivery" increased significantly, indicating that the application of PLGA NPs in photothermal therapy might be the current research hotspot and future development trend of NSCLC treatment. Conclusion Currently, the domestic research on the treatment of nanoparticles and NSCLC is in a leading position in the world. The organic combination of nanoparticles with different materials and other NSCLC therapies is expected to improve the prognosis of NSCLC patients. In the future, attempts to develop nanoparticles with different sources and structures and combined with photothermal therapy for the treatment of NSCLC may become a research hotspot of nanoparticles in the treatment of NSCLC.

Objective:To establish a nomogram model based on elastic imaging parameters and ultrasound image features, and evaluate its predictive value in central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) .Methods:The clinical data of 168 patients (the research group) with papillary thyroid carcinoma who underwent thyroid surgery in our hospital from Jan. 2019 to Dec. 2021 were retrospectively collected, including gender, age, ultrasound elastography parameters (elasticity ratio, blue area ratio), and ultrasound examination indicators (nodule diameter, nodule number, internal echo, border, edge, aspect ratio, microcalcification, capsule invasion). Another 150 patients who underwent thyroid surgery in our hospital during the same period were selected as the validation group.According to the results of postoperative pathological examination, the the research group were divided into two groups: 64 cases (38.10%) of CLNM and 104 cases (61.90%) of non-CLNM. Binary logistic regression analysis was used to explore the influencing factors of CLNM in PTC patients, and a nomogram model based on elastic imaging parameters and ultrasound image features was established. The nomogram model was drawn to predict the receiver operating characteristic (ROC) curve of CLNM in PTC patients.Results:There were statistically significant differences in nodule diameter, edge, microcalcification, capsule invasion, blue area ratio, and elasticity ratio ( P<0.05). Most of the nodules in the CLNM group were ≥10 mm in diameter, with uneven margins, an aspect ratio of <1, microcalcifications and capsular invasion. Logistic regression analysis showed that nodule diameter, capsule invasion, blue area ratio and elastic ratio were risk factors for CLNM ( P<0.05). The AUC of the combined detection was 0.857 (0.777-0.937), and the sensitivity and specificity were 78.1% and 86.5%, respectively, and the AUC and sensitivity were significantly higher than the individual detection of each index ( P<0.05). In the research group, the sensitivity and specificity of the ultrasound parameter prediction model in predicting CLNM were 81.25% (52/64) and 84.62% (88/104), respectively. In the validation group, the sensitivity and specificity of the ultrasound parameter prediction model in predicting CLNM were 79.17% (38/48) and 85.29% (87/102), respectively. Conclusion:Elastography parameters (blue area ratio, elasticity ratio) and ultrasound image features (nodule diameter, capsular invasion) are the influencing factors of CLNM in PTC patients, and the combined prediction based on the above four indicators has good application value.

目的：探讨苍术素（ATR）通过调节受体相互作用蛋白激酶（RIPK）1/RIPK3/混合谱系激酶结构域样（MLKL）信号通路对非小细胞肺癌（NSCLC）A549细胞程序性死亡及裸鼠移植瘤生长的影响。方法：使用0~160 μmol/L的ATR处理A549细胞，MTT法检测细胞存活率以确定后续实验给药浓度。使用ATR和/或RIPK1抑制剂Nec-1（necrostatin-1）、caspase抑制剂Z-VAD-FMK处理A549细胞，验证ATR是否诱导A549细胞发生程序性坏死。将A549细胞分为对照组、ATR-L组、ATR-M组、ATR-H组（分别用0、10、20、40 μmol/L ATR处理）、ATR+Nec-1组（40 μmol/L ATR+50 μmol/L Nec-1处理），处理24 h后，采用PI单染及Hoechst33342/PI双染法检测细胞死亡情况、透射电镜观察细胞死亡形态、DCFH-DA荧光探针法检测细胞内ROS水平、JC-1染色法检测线粒体膜电位、WB法检测细胞中RIPK1/RIPK3/MLKL信号通路相关蛋白质的表达水平。构建A549细胞裸鼠移植瘤模型，用10 mg/kg ATR（溶于玉米油中）对裸鼠灌胃给药5周，观察ATR对移植瘤生长的影响，WB法检测移植瘤组织中RIPK1/RIPK3/MLKL信号通路相关蛋白质的表达水平。结果：10~160 μmol/L的ATR可显著抑制A549细胞增殖，选择10、20、40 μmol/L的ATR进行后续实验。ATR组A549细胞存活率显著低于对照组（P<0.01）和ATR+Nec-1组（P<0.01），而ATR+z-VAD组细胞存活率显著低于z-VAD组（P<0.01），说明ATR可诱导A549细胞发生程序性坏死而非凋亡。与对照组比较，ATR处理组A549细胞发生肿胀，线粒体内脊消失呈空泡化，细胞内容物向外泄漏，细胞核聚集，表现为坏死特征，ATR-L组、ATR-M组、ATR-H组A549细胞死亡率、ROS水平及p-RIPK1、p-RIPK3、p-MLKL表达水平均显著升高，线粒体膜电位显著降低（均P<0.01），且呈药物浓度依赖性；与ATR-H组比较，ATR+Nec-1组细胞死亡率、ROS及p-RIPK1、p-RIPK3、p-MLKL表达水平降低，线粒体膜电位显著升高（均P<0.01）。裸鼠移植瘤实验结果显示，与对照组比较，ATR组裸鼠移植瘤体积、移植瘤质量均降低（P<0.05，或P<0.01），而与瘤组织中p-RIPK1、p-RIPK3、p-MLKL蛋白表达水平均显著升高（均P<0.01）。结论：ATR可能通过激活RIPK1/RIPK3/MLKL信号通路诱导A549细胞发生程序性坏死，抑制A549细胞及其裸鼠移植瘤的生长。

Objective To investigate the mechanism underlying the neuroprotective effect of linarin(LIN)against microglia activation-mediated inflammation and neuronal apoptosis following spinal cord injury(SCI).Methods Fifty C57BL/6J mice(8-10 weeks old)were randomized to receive sham operation,SCI and linarin treatment at 12.5,25,and 50 mg/kg following SCI(n=10).Locomotor function recovery of the SCI mice was assessed using the Basso Mouse Scale,inclined plane test,and footprint analysis,and spinal cord tissue damage and myelination were evaluated using HE and LFB staining.Nissl staining,immunofluorescence assay and Western blotting were used to observe surviving anterior horn motor neurons in injured spinal cord tissue.In cultured BV2 cells,the effects of linarin against lipopolysaccharide(LPS)-induced microglia activation,inflammatory factor release and signaling pathway changes were assessed with immunofluorescence staining,Western blotting,RT-qPCR,and ELISA.In a BV2 and HT22 cell co-culture system,Western blotting was performed to examine the effect of linarin against HT22 cell apoptosis mediated by LPS-induced microglia activation.Results Linarin treatment significantly improved locomotor function(P<0.05),reduced spinal cord damage area,increased spinal cord myelination,and increased the number of motor neurons in the anterior horn of the SCI mice(P<0.05).In both SCI mice and cultured BV2 cells,linarin effectively inhibited glial cell activation and suppressed the release of iNOS,COX-2,TNF-α,IL-6,and IL-1β,resulting also in reduced neuronal apoptosis in SCI mice(P<0.05).Western blotting suggested that linarin-induced microglial activation inhibition was mediated by inhibition of the TLR4/NF-κB signaling pathway.In the cell co-culture experiments,linarin treatment significantly decreased inflammation-mediated apoptosis of HT22 cells(P<0.05).Conclusion The neuroprotective effect of linarin is medicated by inhibition of microglia activation via suppressing the TLR4/NF-κB signaling pathway,which mitigates neural inflammation and reduce neuronal apoptosis to enhance motor function of the SCI mice.
