Atractylodes lancea is a perennial herbaceous plant of Asteraceae, with rhizomes for medical use. However, A. lancea plants from different habitats have great variability, and the germplasm resources of A. lancea are unclear and mixed during production. Therefore, it is urgent to protect new varieties of A. lancea. The distinctness, uniformity, and stability(DUS) testing of new plant varieties is the foundation of plant variety protection, and the DUS testing guidelines are the technical basis for variety approval agencies to conduct DUS testing. In this study, the phenotypic traits of 94 germplasm accessions of A. lancea were investigated considering the breeding and variety characteristics of A. lancea in China. The traits were classified and described, and 24 traits were preliminarily determined, including 20 basic traits that must be tested and four traits selected to be tested. The 20 basic traits included 3 quality traits, 5 false quality traits, and 12 quantitative traits, corresponding to 1 plant traits, 2 stem traits, 8 leaf traits, 6 flower traits, and 3 seed traits. The measurement ranges and coefficients of variation of eight quantitative traits were determined, on the basis of which the grading criteria and codes of the traits were determined and assigned. The guidelines has guiding significance for the trait evaluation, utilization, and breeding of new varieties of A. lancea.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

Objective To evaluate the clinical efficacy of a sphincter-preserving technique combining cutting seton and loose seton drainage for the treatment of ischiorectal abscess.Methods A prospective ran-domized controlled trial was conducted involving 184 patients with ischiorectal abscess,who were randomly di-vided into an experimental group(n=92)and a control group(n=92).The experimental group underwent sphincter-preserving surgery combining cutting seton and loose seton drainage,while the control group re-ceived single-stage incision and seton drainage.Clinical outcomes,anal function,operative time,postoperative pain intensity,wound healing time,and pruritus ani were compared between the two groups.Results The sur-gical time of the experimental group was longer than that of the control group[31.50(25.00,40.00)min vs.20.00(20.00,30.00)min],and the difference was statistically significant(P<0.05).On postoperative days 1,3,and 7,the NRS scores for pain were lower than those in the control group,and the wound healing time was shorter than that in the control group[24.00(20.00,25.75)days vs.29.00(26.00,32.00)days],with statistically significant differences(P<0.05).The recent cure rate of the experimental group was lower than that of the control group(88.04%vs.94.57%),and the difference was not statistically significant(P>0.05).After follow-up,the long-term cure rate of the experimental group was lower than that of the control group(84.78%vs.93.48%),and the Wexner score for anal incontinence was lower than that of the control group[1.00(0.00,1.00)vs.1.00(0.00,2.00)],with statistically significant differences(P<0.05).Conclu-sion The sphincter-preserving technique combining cutting seton and loose seton drainage for ischiorectal ab-scess reduces postoperative pain,shortens wound healing time,and effectively protects anal function with reli-able short-term efficacy.However,further improvements are needed to enhance long-term clinical outcomes.

Objective To summarize the clinical characteristics of 2 cases of styloid-carotid syndrome(SCS)and review the literature to enhance understanding of the disease.Methods A retrospective analysis was conducted on the clinical manifestations,auxiliary examinations,and diagnosis and treatment of 2 patients with SCS admitted to the Neurology Department of Kaifeng Central Hospital.Additionally,relevant literature was searched through domestic and foreign databases such as PubMed,WOS,Embase,CNKI and VIP.The clinical characteristics of SCS were summarized based on the literature results.Results The 2 cases were diagnosed as transient cerebral ischemia(TIA)combined with SCS through head and neck CT angiography(CTA)and styloid process CT.Apart from the 2 cases treated in our hospital,a total of 11 cases of SCS have been reported in Chinese and English literature up to October 2023.Among the 13 cases,11 cases(84.6%)started with episodic TIA symptoms,and 11 cases(84.6%)had obvious inducing factors related to specific head position changes.Common clinical manifestations included unilateral limb weakness with or without sensory disturbance(10 cases,76.9%),slurred speech(7 cases,53.8%),unilateral limb sensation disorder(4 cases,30.7%),syncope(3 cases,23.1%)and amaurosis(2 cases,15.4%).All 13 cases underwent 64-row head and neck CTA examination,and 6 cases(46.2%)dynamically observed the changes in blood flow velocity through examinations such as transcranial Doppler ultrasound(TCD),cervical vascular ultrasound,and digital subtraction angiography(DSA).All patients were followed up for more than 3 months;and 10 cases(76.9%)achieved clinical cure after treatment,of which 8 cases underwent styloid process shortening surgery;3 cases(23.1%)achieved clinical symptom improvement after treatment.Conclusions For patients with recurrent TIA and/or cerebral infarction,it is necessary to identify whether there are inducing factors related to specific body position changes.For patients highly suspected of SCS,routine examinations such as styloid process CT and 64-row head and neck CTA should be performed,and if necessary,whole brain DSA,dynamic TCD and/or carotid ultrasound should be conducted to guide the diagnosis and treatment.When non-surgical treatment is ineffective,radical styloid process truncation can be considered as a treatment option.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

Atopic dermatitis is usually associated with various ocular complications.We report a 21-year-old Chinese male who presented to our ophthalmology clinic with bilateral retinal detachment and cataracts.The patient had a clear medical history of atopic dermatitis,which had been diagnosed eight years earlier and had been treated with loratadine and pimecrolimus.Cataract surgery was performed for both eyes,combined with scleral buckling for the right eye and pars plana vitrectomy for the left eye.During postoperative follow-up,fundus fluorescein angiography showed retinal vasculitis in both eyes and macular edema in the left eye,which coincided with an exacerbation of atopic dermatitis.Macular edema improved after four months of regular dupilumab treatment in the dermatology department.The ocular condition remained stable three years postoperatively.

Objective To evaluate the application of three deep learning algorithms in automatic segmentation of clinical target volumes (CTVs) in high-dose-rate brachytherapy after surgery for endometrial carcinoma. Methods A dataset comprising computed tomography scans from 306 post-surgery patients with endometrial carcinoma was divided into three subsets: 246 cases for training, 30 cases for validation, and 30 cases for testing. Three deep convolutional neural network models, 3D U-Net, 3D Res U-Net, and V-Net, were compared for CTV segmentation. Several commonly used quantitative metrics were employed, i.e., Dice similarity coefficient, Hausdorff distance, 95th percentile of Hausdorff distance, and Intersection over Union. Results During the testing phase, CTV segmentation with 3D U-Net, 3D Res U-Net, and V-Net showed a mean Dice similarity coefficient of 0.90 ± 0.07, 0.95 ± 0.06, and 0.95 ± 0.06, a mean Hausdorff distance of 2.51 ± 1.70, 0.96 ± 1.01, and 0.98 ± 0.95 mm, a mean 95th percentile of Hausdorff distance of 1.33 ± 1.02, 0.65 ± 0.91, and 0.40 ± 0.72 mm, and a mean Intersection over Union of 0.85 ± 0.11, 0.91 ± 0.09, and 0.92 ± 0.09, respectively. Segmentation based on V-Net was similarly to that performed by experienced radiation oncologists. The CTV segmentation time was < 3.2 s, which could save the work time of clinicians. Conclusion V-Net is better than other models in CTV segmentation as indicated by quantitative metrics and clinician assessment. Additionally, the method is highly consistent with the ground truth, reducing inter-doctor variability and treatment time.
