As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Background/Aims: Helicobacter pylori may protect against immune-mediated disorders such as inflammatory bowel disease (IBD) and asthma. This study evaluated whether eradication was associated with IBD and asthma in Korean children. Methods: Data were collected from the Korean National Health Insurance information on patients younger than 18 years and without a prior diagnosis of IBD or asthma from January 2007 to September 2020. Patients confirmed with H. pylori infection were divided into the eradication and non-eradication group. We compared the incidence of IBD and asthma in infected patients with an age, and sex-matched control group. Results: In total, 979,663 patients were selected based on the inclusion criteria and 2,779 patients were included based on the exclusion criteria. The occurrence of IBD in infected patients was statistically significant (p < 0.05) but there was no association of infection with asthma. There was no association with eradication and the development of IBD and asthma. The infected group had a shorter duration till diagnosis of IBD than the control group. Conclusions Our study found H. pylori infection to be associated with the development of IBD in children. However, eradication does not increase IBD and asthma in children.

Background/Aims: Spinal cord injury (SCI) frequently impairs defecation, severely affecting the quality of life. This study examines compensatory neural remodeling after SCI, focusing on basal colonic contractility, neural responses to electrical field stimulation, and alterations in excitatory cholinergic and inhibitory nitrergic pathways. Methods: Female Sprague–Dawley rats underwent either sham surgery or T10 spinal cord transection and were categorized into 3 groups: sham, 1-week post-SCI (acute), and 4-week post-SCI (chronic). Colonic contractility was assessed in an organ bath using electrical field stimulation in the presence of a nitric oxide synthase inhibitor. Neural protein expression was analyzed by immunofluorescence and Western blotting. Results: SCI produced region- and time-dependent impairments in colonic contractility, with distinct alterations in the proximal circular and longitudinal muscles across acute and chronic phases. Neural excitability shifted dynamically, showing enhanced excitatory activity in the proximal longitudinal muscle at 1-week and the distal circular muscle at 4-week post-SCI. Protein analysis revealed increased neuronal nitric oxide synthase in the proximal colon, decreasedsoluble guanylyl cyclase in the distal colon, upregulated muscarinic M3 receptor in the proximal colon, and reduced vaso-active intestinal peptide receptor 1 in both proximal and distal regions. Conclusion SCI induces spatiotemporal remodeling of excitatory and inhibitory neural pathways, contributing to colonic dysmotility and revealing potential targets for therapeutic intervention.

Objective To investigate the diagnostic value of masseter muscle thickness fraction(MMTF)measured by ultrasound for the occurrence of dysphagia in patients with Parkinson's disease(PD).Methods A total of 100 patients were selected as the study group,and another 50 healthy individuals who received medical checkups with matched age,gender and body mass index(BMI)in our hospital during the same period were selected as the control group.The demographic data and disease characteristics of PD patients were recorded,and patients were divided into the dysphagia group(n=34)and the non-dysphagia group(n=66)according to the occurrence of dysphagia.The demographic data,and disease characteristics such as Hoehn-Yahr(H&Y)stage,Unified Parkinson's Disease Rating Scale(UPDRS)Ⅲ score,levodopa equivalent daily dose(LEDD)and MMT-related parameters measured by ultrasound were compared between the two groups.The indicators with P＜0.05 in univariate analysis were used as independent variables,and the influencing factors of dysphagia in patients with PD were investigated by binary Logistic regression analysis.The diagnostic efficacy of each index for dysphagia in patients with PD was evaluated by constructing receiver operating characteristic(ROC)curves,and the area under the curve(AUC)was calculated.Results The MMT during forceful biting and MMTF were lower in the study group than those in the control group(all P＜0.05).Compared with the non-dysphagia group,the dysphagia group was older and had higher H&Y stage and UPDRS III scores(all P＜0.05).The MMT during forceful biting and MMTF in the dysphagia group were lower than those in the non-dysphagia group(all P＜0.05).Multivariate Logistic regression analysis showed that increased UPDRSⅢ score was the risk factor for dysphagia in patients with PD,and increased MMT during forceful biting and MMTF were protective factors.The ROC curve analysis indicated that the AUC(95%CI)of UPDRS Ⅲ score,MMT during forceful biting and MMTF for diagnosing dysphagia in patients with PD were 0.714(0.615-0.800),0.744(0.647-0.826)and 0.888(0.809-0.942),respectively.The AUC of MMTF for diagnosing dysphagia in patients with PD was higher than those of UPDRS Ⅲscores and MMT during forceful biting(Z values were 2.611 and 2.208,respectively,P＜0.05).Conclusion MMTF is an independent influencing factor for dysphagia in patients with PD and can be used as a screening indicator for dysphagic patients.

Objective To establish a highly sensitive and specific method for detecting human DNA based on real time quantitative PCR(qPCR)technique for the rapid detection of potential DNA con-tamination sources in DNA laboratories.Methods Primers and probes were designed with Primer Ex-pressTM software using the reference sequence of human 18S rRNA gene as a template,and the opti-mal prime-probe combination was screened by matrix method.The PCR products of the target se-quence of human 18S rRNA gene were used to construct the plasmid,and a plasmid standard was used to draw the standard curve of the qPCR system.According to the Minimum Information for Pub-lication of Quantitative Real-time PCR Experiments(MIQE)guidelines,the specificity,sensitivity,re-peatability and application effect of the qPCR system were evaluated.Results The sensitivity of the qPCR system established in this study was 5.3×10-5 ng/μL,which showed good specificity for human DNA samples.The correlation coefficient of the qPCR system was-0.999,and amplification efficiency was 100％.Both the intra-batch and inter-batch variation coefficients were less than 2％.Conclusion The established human DNA detection method based on qPCR technique has good specificity,high sen-sitivity,and robust stability.It can be used for rapid detection of DNA contamination and daily moni-toring of the accumulated human DNA in the laboratory environment.

Objective:To evaluate the clinical efficacy of botulinum toxin type A (BTX-A) injection in enhancing chin aesthetics.Methods:A retrospective analysis was conducted on patients with suboptimal chin aesthetics who underwent dual-plane BTX-A injection at Plastic Surgery Hospital, Chinese Academy of Medical Sciences between August 2023 and March 2024. Prior to injection, patients were instructed to repeatedly pucker their lips forward and upward to identify the most prominent points of the mentalis muscle for injection. A 13 mm 30 G needle was inserted perpendicularly into the muscle layer, and BTX-A was administered at a concentration of 20 U/ml, with 3 U per injection point. For the patients exhibiting significant orange peel signs at rest, intradermal deep-layer BTX-A injection was concurrently performed at a concentration of 5 U/ml, with 0.5 U per linear track. Postoperative follow-up was conducted, and third-party physicians assessed pre- and post-treatment photographs using the global aesthetic improvement scale (GAIS) (scores ranging from 5 to 1, representing worse, no improvement, mild improvement, moderate improvement, and significant improvement, respectively). Patient satisfaction was also surveyed [categorized as very satisfied, satisfied, dissatisfied, or very dissatisfied; satisfaction rate = (very satisfied + satisfied) cases/total cases × 100%], along with their willingness to undergo repeated injections and recommend the procedure to others. Descriptive statistical analysis was performed using SPSS 24.0 software. Normally distributed continuous data were expressed as Mean±SD, and categorical data were expressed as counts (%).Results:A total of 120 patients were included, comprising 11 males and 109 females, aged 22-39 years (mean age of 33.3 years). Follow-up ranged from 1 to 5 months (mean of 1.3 months). Postoperatively, 102 patients reported subjective improvement in chin appearance, characterized by enhanced fullness and roundness of the chin. Thirty-one patients noted a slight elevation of the submental fat pad and improved definition of the cervicomental angle. The mean GAIS score was 1.61±0.78, with 76 cases scoring 1, 24 cases scoring 2, 10 cases scoring 3, and 10 cases scoring 4. Improvement (scores 1-3) was achieved in 91.7% (110/120) of patients. The subjective satisfaction rate was 85.0% (102/120), and 94 patients (78.3%) expressed willingness to undergo repeated injections and recommend the procedure to family or friends. Early postoperative complications included localized bruising in 17 cases, which was resolved within 10 d, and transient fine motor dysfunction of the lower jaw in 23 cases, with normal chewing, swallowing, and facial expressions, all of which were resolved completely within 6 weeks. No cases of mouth deviation, facial paralysis, allergic reactions, or other complications were observed.Conclusion:The application of BTX-A via intramuscular mentalis injection combined with intradermal deep-layer injection significantly improves both dynamic and static chin aesthetics. However, some common complications also ask for the further attention of practitioners.

Atopic dermatitis is the most common chronic inflammatory skin disease in children and adolescents. The Korean Academy of Pediatric Allergy and Respiratory Disease published the Atopic Dermatitis Treatment Guideline in 2008, which has been helpful in atopic dermatitis treatment until now. Various reports on the development and effectiveness of new drugs have suggested that there is a need to develop and revise old treatment guidelines. Part 1 aimed to provide evidence-based recommendations for skin care management and topical treatment for atopic dermatitis. Part 2 focuses on systemic treatment, novel therapeutics, and adjuvant therapy. The goal of this guideline is intended to assist front-line doctors treating pediatric and adolescent atopic dermatitis patients make safer, more effective, and more rational decisions regarding systemic treatment, novel therapeutics, and adjuvant therapy by providing evidence-based recommendations with a clear level of evidence and benefit regarding treatment.
