ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine （TCM） surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted， collecting clinical data from 17，831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group （11,646 cases）， and those receiving TCM surgical operations were categorized into the TCM surgery group （6185 cases）. Propensity score matching （1∶1 matching） was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate， and secondary outcomes included the main symptoms （rectal bleeding， degree of prolapse） and secondary symptoms （anal distension， anal edema， wound secretion and exudation， anal stenosis， residual skin tags， perianal itching， and anal pain） measured on days 7， 28， and 60 after discharge. ResultsAfter matching， 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge， the TCM surgical group had superior improvement in rectal bleeding ［OR=5.786， 95%CI （3.092，10.827）］， degree of prolapse ［OR=4.510， 95%CI （1.649，12.333）］， and anal edema ［OR=3.188， 95%CI （1.295，7.845）］ compared to the western surgical group. At 60 days post-discharge， the TCM group still showed advantages in improving rectal bleeding ［OR=5.237， 95%CI （1.077，25.464）］ and anal pain ［OR=11.697， 95%CI （1.186，115.336）］ （P＜0.05）. Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% （8/726）， while that in the western surgery group was 2.3% （10/444）， with no statistically significant difference between the two groups （P＞0.05）. ConclusionBased on real-world data， TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement， particularly in terms of hemostasis， reducing swelling， and alleviating prolapse of anal masses.

Objective:To digitally measure the three-dimensional (3D) size of primary tooth crowns and the dimensions of the dental arch in children with individual normal primary dentition, preliminarily obtaining baseline data on the 3D size of primary tooth crowns as well as the length and width of the dental arch, and their influence factors. This study aims to provide a data foundation for the design of reference models for primary dentition.Methods:From May to June 2021, 122 caries-free children aged 3.5-4.5 years with individual normal occlusion were selected from five kindergartens in Haidian District, Beijing. Impressions were taken and plaster models were cast. After preliminary screening, 67 eligible models were scanned to obtain digital dental models. Digital measurement software was used for landmark-based measurements. Parameters included 3D crown dimensions (mesiodistal diameter, buccolingual diameter, and occlusogingival height), dental arch dimensions (length and width at specific regions), and occlusal measurements (overjet and overbite at the primary central incisors, and Bolton index for anterior and full dentition). Gender differences in crown dimensions and bilateral symmetry of homologous teeth, as well as the correlations between arch dimensions and gender, height, weight, and body mass index (BMI) were analyzed.Results:The homonymous teeth of 67 children exhibited strong bilateral symmetry in all 3D dimensions ( P>0.05). Gender differences were observed in the buccolingual dimension for all deciduous molars except for the right mandibular first deciduous molar ( P<0.05). For the occlusogingival dimension, gender differences were found in the right maxillary first and second deciduous molars, left maxillary first deciduous molar, and left mandibular first and second deciduous molars ( P<0.05). For the mesiodistal dimension, only the left mandibular second deciduous molar and right mandibular deciduous canine showed gender differences ( P<0.05). All significant differences above indicated larger dimensions in boys compared to girls. In both maxillary and mandibular arches, the lengths and widths at various locations were significantly larger in boys than in girls ( P<0.05). Univariate correlation analysis revealed that body weight was positively correlated with the width of the terminal plane in both the maxilla and mandible and the total length of the mandibular dental arch, while BMI was positively correlated with the width of the maxillary terminal plane and the widths at all measured sites in the mandible ( P<0.05). Multiple regression analysis demonstrated that, after controlling for relevant variables, BMI was a significant positive predictor for the lengths and widths at various sites of the dental arch ( P<0.05), and height was a positive predictor for dental arch length ( P<0.05), as well as body weight was a positive predictor for the width in the molar region ( P<0.05). Overjet at the primary central incisors was 2.28 (1.57, 2.66) mm, and overbite was 1.13 (0.75, 1.92) mm. The anterior Bolton index was 0.79±0.03, and the overall Bolton index was 0.94±0.03. Conclusions:Primary tooth crowns of individual normal occlusion children demonstrate strong bilateral symmetry in homologous teeth. Most primary molars exhibit gender differences in buccolingual and occlusogingival dimensions, with larger values in boys. Arch dimensions (length and width) are consistently larger in boys.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Objective:To explore the efficacy of a bleeding risk graded management program in patients with lower extremity deep vein thrombosis (DVT) undergoing catheter-directed thrombosis (CDT) .Methods:Convenience sampling was used to select 100 DVT patients who underwent CDT from October 2021 to December 2023 in the Nanjing First Hospital as study subjects. According to the propensity matching score ratio of 1: 1, patients were divided into control group and observation group, with 50 cases in each group. Control group implemented CDT routine nursing and rehabilitation exercises, and observation group implemented a bleeding risk graded management program based on control group by dynamically monitoring changes in plasma fibrinogen and blood pressure. Differences in the rates of swelling reduction in the limbs, venous patency, bleeding events and hospitalization satisfaction were compared between the two groups.Results:After the intervention, the swelling reduction rate of the limbs of DVT patients in observation group was (85.07±11.96) %, and the rate of venous patency was (89.00±25.33) %, and that of control group was (70.85±21.73) %, (75.00±35.36) %, and the differences were statistically significant (all P<0.05). The rate of bleeding events was lower in the observation group than in the control group, and the difference was statistically significant ( P<0.05). The difference in hospitalization satisfaction between the two groups was not statistically significant ( P>0.05) . Conclusions:The bleeding risk graded management program developed after comprehensive assessment can realize the balance between the therapeutic benefit and bleeding risk of CDT for DVT patients, and can improve the safety and effectiveness of CDT.

Objective To investigate the effect of local vibration therapy(LVT)on fine motor function of upper extremity and surface electromyography characteristics in children with spastic hemiplegic cerebral palsy(SHCP).Methods Sixty children with SHCP were divided into the observation group and the control group using random number table method,with 30 cases in each group.The control group was given conventional rehabilitation treatment(physical therapy,occupational therapy,sensory integration training,physiotherapy and rehabilitation therapy of traditional Chinese medicine),while the observation group received LVT for the affected upper extremity in addition to conventional rehabilitation treatment.Both groups were treated for 12 weeks.Fine motor function of upper extremity on the hemiplegic side[Peabody Developmental Motor Scale-Fine Motor(PDMS-FM),Fine Motor Function Measure(FMFM)]and root mean square(RMS)value of the biceps surface electromyography were compared between the two groups as well as before and after treatment.Results Compared with those before treatment,both groups showed increases in PDMS-FM scores for grasping energy range,visual-motor integration energy range,fine motor development quotient,FMFM scores for upper extremity joint mobility ability,grasping ability,operation ability,hand-eye coordination ability and total scores,but a decrease in RMS value of biceps brachii after treatment(P＜0.05).After treatment,PDMS-FM scores for grasping energy range and visual-motor integration energy range,FMFM scores for upper extremity joint mobility ability and grasping ability and total score were higher in the observation group than those in the control group.The RMS value of biceps brachii was lower in the observation group than that of the control group(P＜0.05).Conclusion LVT can enhance the effect of conventional rehabilitation on fine motor function of upper extremity and electromyography characteristics in children with SHCP.

Objective:To summarize and analyze the clinical characteristics of pediatric pulmonary hypertension (PH) and the related factors affecting the prognosis，to provide a basis for the early diagnosis and treatment of the disease.Methods:The clinical data of 80 PH children hospitalized in the intensive care department of Children's Hospital of Capital Pediatric Research Institute from January 1,2019 to December 31,2022 were retrospectively analyzed,and general data,clinical symptoms, echocardiography, laboratory examination and treatment indicators were collected. According to survival death groups, multivariate Logistic regression was applied to analyze independent associated risk factors for PH death.Results:（1）Clinical characteristics of childhood PH: more common in infants, the average age of treatment was 0.9(0.3-5.3)years, the male to female ratio was 1.3∶1, and the average time from first symptoms to first diagnosis was 6.5 (2,14) days. The etiology of PH in children was complex, with arterial PH (PAH) (40%), pulmonary disease and(or) hypoxia (33.8%) being the most common. The main clinical manifestations were dyspnea, decreased activity endurance, poor appetite, and positive heart examination. Severe PH accounted for 53.8%, 30% of pulmonary hypertensive crisis.（2）Factors affecting the prognosis of childhood PH: childhood PH mortality was 20.8%, compared with the survival group, ICU length of stay, loss of appetite, decreased urine volume, cardiac function classification, right heart size, main pulmonary artery diameter/ascending aorta diameter ratio(MPAD/MAD), vasoactive inotropic score(VIS), use of invasive ventilator treatment had statistical significance (all P<0.05). A Logistic regression analysis of death-related factors showed that right heart enlargement ( OR=0.193,95% CI 0.040-0.919, P=0.039), higher MPAD/MAD value ( OR =11.883,95% CI 1.347-104.869, P=0.026), and higher VIS score ( OR= 1.029,95% CI 1.003-1.056, P=0.028) were independent risk factors for poor prognosis. Conclusion:（1）Children PH is mainly infants, the causes of PAH and pulmonary diseases, severe PH accounted for 53.8%, 30% of which have pulmonary hypertensive crisis.（2）An enlarged right heart, higher MPAD/MAD values, and higher VIS score are independent risk factors for death in children with PH.

Objective:To systematically evaluate the fairness of traditional Chinese medicine (TCM) healthcare resource allocation at the prefecture-level in China using the healthcare resource agglomeration degree (HRAD) method, so as to provide empirical evidence for optimizing resource distribution.Methods:Data on TCM healthcare resources (including the number of TCM institutions, public TCM hospitals, TCM hospital beds, and TCM healthcare technicians) were collected from 333 prefecture-level regions in 2023. The HRAD method was employed to assess fairness in geographic allocation (HRAD i) and population-based allocation (HRAD i/PAD i). A multi-indicator comprehensive evaluation was conducted using the entropy weight method to determine weighting coefficients. Results:Significant disparities were observed in the geographic agglomeration of TCM resources (HRAD i) in China. Resource-rich regions (HRAD i>5) were primarily concentrated in eastern and some central-western provinces, while resource-scarce regions (HRAD i<1) were mainly distributed in western, northeastern, and parts of central and eastern provinces. Analysis of population-based fairness (HRAD i/PAD i) revealed that most prefecture-level cities nationwide had ratios<1, with only 8 provinces having more cities with ratios>1 than<1. The comprehensive evaluation showed that top-ranked cities in the east (e.g., Hangzhou, Dongying, Shenzhen), central region (e.g., Taiyuan, Zhengzhou), and west (e.g., Hainan Prefecture, Alxa League) were predominantly core cities or sparsely populated areas. Conclusions:China′s prefecture-level TCM healthcare resource allocation exhibits significant geographic and population-based inequities, with excessive concentration in provincial capitals and developed cities. Urgent strategies are needed to optimize resource allocation, enhance fairness and accessibility, including promoting the decentralization of high-quality resources, strengthening regional collaborative support, enhancing talent attraction in underdeveloped areas, and leveraging information technology to improve efficiency.
