Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective:To investigate the prevalence of small intestinal bacterial overgrowth (SIBO) in patients with rosacea, and to analyze the relationship between breath test results and the occurrence of rosacea.Methods:Patients with rosacea were enrolled from the outpatient department of Xiangya Hospital from March 2022 to June 2023. The methane-hydrogen breath test was used to detect intestinal levels of methane and hydrogen in all patients to investigate the prevalence of SIBO. The basic information, clinical symptoms and severity, quality of life scores, gastrointestinal symptoms, and past medical history of the patients were collected. Statistical analysis was carried out by using the chi-square test, nonparametric test and multivariate logistic regression models to investigate the relationship between SIBO and the occurrence of rosacea.Results:A total of 116 patients with rosacea completed the methane-hydrogen breath test. They were aged 18 to 56 years (median [ Q1, Q3]: 25 [22, 33] years), and included 7 males (6.0%) and 109 females (94.0%) ; there were 43 cases (37.1%) of erythematotelangiectatic rosacea, and 73 (62.9%) of papulopustular rosacea. As the breath test showed, 94 patients were diagnosed with SIBO (81.0%, 95% CI: 72.7% - 87.7%) based on the breath tests, 84 showed positive hydrogen breath test results (72.4%, 95% CI: 63.3% - 80.3%), and 47 had positive methane breath test results (40.5%, 95% CI: 31.5% - 50%). Among the 67 patients with moderate to severe erythema, 33 (49.3%) showed positive methane breath test results, and 14 of 49 (28.6%) patients with mild erythema showed positive methane breath test results, with a rate difference of 20.7% ( P = 0.025, 95% CI: 13.9% - 27.5%) ; there were no significant differences in the positive rates of SIBO and hydrogen breath test results between the patients with moderate to severe erythema and those with mild erythema (both P > 0.05). No significant differences were observed in the age, gender, clinical subtypes, severity of papulopustules, flushing and burning sensation, or rosacea quality of life index scores between the SIBO-positive and -negative groups, between hydrogen-positive and -negative groups, and between methane-positive and -negative groups (all P > 0.05). Multivariate logistic regression analysis showed that methane positivity on breath test was associated with the severity of erythema in rosacea ( OR = 2.495, 95% CI: 1.102 - 5.649, P < 0.05) . Conclusions:The prevalence of SIBO was relatively high in the patients with rosacea. However, only the positive rate of methane breath test differed between the rosacea patients and non-rosacea controls, and there was some correlation between methane positivity on breath test and increased severity of rosacea erythema.

Objective:To compare the efficacy of staged versus elective operation for treating acute closed fracture-dislocation of tarsometatarsal joint complex.Methods:A retrospective cohort study was used to analyze the clinical data of 26 patients with acute closed fracture-dislocation of tarsometatarsal joint complex admitted to Tongji Hospital of Tongji University from January 2017 to January 2021, of whom 18 were males and 8 were females, aged 32-52 years [(44.3±5.2)years]. According to the time from injury to admission, 14 patients admitted within 8 hours after injury underwent staged surgical treatment (staged group), and 12 patients admitted more than 8 hours after injury underwent elective surgery (elective group). In the staged group, emergency reduction and temporary internal fixation with K-wire were done under the supervision of a C-arm X-ray machine in the first stage, while after the swelling subsided, open reduction and internal fixation were done for tarsometatarsal joint fracture-dislocation in the second stage. In the elective group, open reduction and internal fixation were performed for tarsometatarsal joint fracture-dislocation on a scheduled basis after the swelling subsided. The operation time, hospitalization time and fracture healing time were recorded. The visual analogue score (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) midfoot score were evaluated before operation, at 1, 6, 12 months after operation and at the final follow-up. The rate of complications was observed after operation.Results:All patients were followed up for 12-24 months [(18.5±3.8)months]. The operation time, hospitalization time and fracture healing time in the staged group were (77.3±5.6)minutes, (14.3±2.2)days and (12.3±1.2)weeks, respectively, significantly shorter than those in the elective group [(101.5±7.5)minutes, (20.3±5.2)days and (14.3±2.2)weeks] (all P<0.01). VAS significantly decreased and AOFAS midfoot score significantly increased in both groups as postoperative time increased (all P<0.05). There were no significant differences in VAS between the two groups before operation, at 12 months after operation or at the final follow-up (all P>0.05). The VAS at 1, 6 months after operation was (4.4±0.8)points and (2.1±0.4)points in the staged group, significantly lower than those in the elective group [(6.0±1.0)points and (3.5±0.6)points] (all P<0.01). There was no significant difference in preoperative AOFAS midfoot score between the two groups ( P>0.05). The AOFAS midfoot score at 1, 6, 12 months after operation and at the final follow-up was (67.6±4.5)points, (75.7±5.2)points, (83.6±2.2)points and (85.9±4.3)points in the staged group, significantly higher than those in the elective group [(60.2±3.9)points, (70.2±3.4)points, (75.4±3.3)points and (78.7±4.4)points] (all P<0.01). The rate of complications was 14.3% (2/14) in the staged group, significantly lower than that in the elective group [33.3% (4/12)] ( P<0.05). Conclusion:Compared to traditional elective surgery, staged surgery for acute closed fracture-dislocation of tarsometatarsal joint complex has the advantages of shortened operation time, hospitalization time and fracture healing time, eary pain relief, improved functional recovery of the foot and reduced postoperative complications.

Objective To analyze the survival status, distribution characteristics and social security of newly diagnosed occupational pneumoconiosis patients in Guizhou Province from 2006 to 2021. Methods The newly diagnosed pneumoconiosis cases reported in Guizhou Province from 2006 to 2021 were collected from the “Occupational Diseases and Hazards Monitoring Information System” under “National Health Insurance Disease Prevention and Control Information System”. Telephone or face-to-face surveys were conducted to investigate these patients. Results A total of 12 413 newly diagnosed pneumoconiosis patients were reported in Guizhou Province from 2006 to 2021, with 11 192 cases included in the follow-up, and 10 631 cases were followed-up successfully. According to the follow-up study, 10 565 cases (accounting for 99.4%) were survived, and 66 cases (accounting for 0.6%) died. The number of pneumoconiosis showed an increasing trend followed by a sharp decline from 2006 to 2021, reaching its peak in 2016. The main industry of the newly pneumoconiosis cases was concentrated in the mining industry (accounting for 90.6%). The top three regions with surviving cases in the follow-up were Bijie City, Zunyi City, and Qiannan Prefecture, accounting for 34.0%, 25.4% and 12.0%, respectively. The main types of pneumoconiosis were coal workers' pneumoconiosis and silicosis, accounting for 67.1% and 30.8%, respectively. Most cases were in the age group of 50 to <60 years old, accounting for 59.1%, and the majority of the workers had worked in dusty environments for 5 to <25 years, accounting for 91.5%. In terms of social security, about 89.5% of cases were in the basic medical insurance for urban and rural residents which was the most popular social security. The employer's compensation rate was 67.7%, and the work-related injury insurance participation rate was 51.5%. Conclusion Pneumoconiosis cases in Guizhou Province exhibit significant regional disparities. It has a high concentration in the industry, a younger age profile, and limited social security coverage. It is necessary to strengthen the special management of dust and industry supervision in mining industry, intensify follow-up work for pneumoconiosis cases, reinforce the construction of pneumoconiosis rehabilitation station in key regions, and improve the quality of life of pneumoconiosis cases.

Objective To study the influencing factors of blood stasis constitution and provide a basis for treating blood stasis-related diseases by traditional Chinese medicine (TCM) constitution identification. Methods Data were collected using the self-developed TCM constitution identification platform based on B/S model by the project team. The obtained data were divided into blood stasis constitution and normal constitution groups. The differences of the categorical type influencing factors (gender, birth mode, feeding mode within four months of birth, family history, marital status, eating habits, sleeping habits, exercise habits, emotional state, stress situation, and living environment) and the quantitative type influencing factors (sleep time, age, and mother's age at birth) on the constitution of the two groups were analyzed. In the single-factor analysis, the Pearson's chi-square test was selected for the categorical variable, and the independent sample t test and Mann-Whitney U nonparametric test were selected for the quantitative variables according to whether they conformed to the positive-terrestrial distribution; the binary logistic stepwise regression method was selected for the multi-factor analysis. Results The data of 318 cases were collected from the TCM composition identification platform, and 159 cases of blood stasis constitution were used as the experimental group and 159 cases of normal constitution were used as the control group. The Pearson's chi-square test yielded significant differences (P < 0.05) in the effects of gender, pressure situation, family history, living environment, emotional state, exercise habits, and dietary habits on blood stasis constitution. The independent samples t test yielded differences in sleep duration between the blood stasis constitution and normal constitution populations (P < 0.05), which meant sleep duration of the blood stasis constitution population was less than that of the normal constitution population. The Mann-Whitney U nonparametric test results accepted the original hypothesis that there was no difference in the distribution of age and mother’s age at birth across constitution types (P > 0.05). Binary logistic regression analysis showed that gender, family history, marital status, living environment, exercise habits, and emotional state were risk factors for blood stasis constitution (P < 0.05). Conclusion Gender, family history, living environment, emotional state, and exercise habits were significant influencing factors of blood stasis constitution. Blood stasis constitution populations can pay more attention to these influencing factors in their daily life for the prevention and reconciliation of blood stasis constitution.

Objective:To propose a new classification of posterior malleolus fracture to further clarify its pathoanatomy.Methods:Twenty fresh frozen cadaver specimens of normal morphology of lower limbs were selected and dissected and the extent of the tibial insertion of posterior malleolus associated ligaments was measured. At the same time, a retrospective case series analysis was made on the clinical and CT information of 296 patients with posterior malleolus fracture treated at Tongji Hospital of Tongji University from January 2012 to July 2020 or at Karamay Central Hospital from January 2018 to July 2020. The percentage of articular involvement of the fracture, proximal displacement of the posterior malleolus fracture and extent of posterior talar subluxation were measured. A clinically practical new classification system for posterior malleolus fracture was created by correlating posterior malleolus associated ligaments with CT images of posterior malleolus fracture. The new classification included three types: type I was posterior malleolus fracture with only the tibial insertion of inferior transverse tibiofibular ligament involved; type II was posterior malleolus fracture with both the tibial insertions of inferior transverse tibiofibular ligament and posterior inferior tibiofibular ligament involved, which was divided into subtypes IIA and IIB based on the presence of articular cartilage and subchondral bone damage, compression or Die-Punch fragments; type III was posterior malleolus fracture that involved all the tibial insertions of inferior transverse tibiofibular ligament, posterior inferior tibiofibular ligament and posterior tibiotalar ligament, which was sub-classified into subtypes III A and III B according to number of fracture fragments. Anatomic characteristics of the extent of the tibial insertion of posterior malleolus associated ligament, CT imaging parameters for posterior malleolus fracture and corresponding fracture typing were determined. In addition, the new classification system for posterior malleolus fracture was compared with Haraguci classification and Mason classification.Results:Posterior malleolus associated ligaments included the posterior inferior tibiofibular ligament, inferior transverse tibiofibular ligament and posterior tibiotalar ligament from posterolateral to posteromedial tibia. The posterior inferior tibiofibular ligament was attached to the posterolateral tibia and the distance between the highest point of its tibial insertion and the joint line was (45.2±5.6)mm. The inferior transverse tibiofibular ligament was attached to the posterior distal tibia and the distance between the highest point of its tibial insertion and the joint line was (5.5±1.0)mm. The posterior tibiotalar ligament was attached to the posterior colliculus and intercollicular groove of the medial malleolus and the distance between the center of its tibial insertion and the intercollicular groove was (2.5±0.6)mm. Among 296 patients with posterior malleolus fracture, there were 36 patients with type I, 229 with type II (150 type IIA, 79 type IIB) and 31 with type III (11 type IIIA, 20 type IIIB). The percentage of articular involvement of the fracture, proximal displacement of posterior malleolus fracture and extent of posterior talar subluxation in type IIB fracture were significantly greater than those in type II A fracture [23.7(18.6, 28.8)% vs. 18.4(12.7, 21.7)%, 4.1(2.1, 6.0)mm vs. 1.9(0.2, 3.0)mm, 4.7(1.5, 6.2)mm vs. 2.3(1.1, 3.0)mm] (all P<0.01). The proximal displacement of posterior malleolus fracture and extent of posterior talar subluxation in type III fracture were significantly greater than those in type II fracture [7.2(6.0, 8.2)mm vs. 2.7(0.4, 4.0)mm, 10.1(6.0, 15.0)mm vs. 3.1(1.1, 5.0)mm] (all P<0.01). The new classification for posterior malleolus fracture combined the posterior malleolus ligament and injury mechanism of posterior malleolus fracture as compared with Haraguchi classification, which not only further detailed the classification, but also was more practical in clinic for increased the severity of injury was elevated with higher classification level. The new classification was more comprehensive as compared with Mason classification for it mainly added the type of simple-rotation-type posterior malleolus fracture (type IIA of the new classification). Conclusions:In combination with posterior malleolus associated ligaments, injury mechanism and fracture morphology, posterior malleolus fracture is divided into three types. The new classification system more comprehensively describes pathoanatomy of posterior malleolus fracture that contributes to related basic research and clinical diagnosis and treatment.

Objective:To investigate the efficacy of TiRobot navigation combined with ankle arthroscopy in the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture.Methods:From January 2019 to September 2020, a total of 13 patients with Hawkins type Ⅱ talus neck fracture were admitted to Department of Foot and Ankle Surgery, Xuzhou Renci Hospital. They were 8 males and 5 females, with a mean age of 35.8 years (from 22 to 61 years). All fractures were reduced and fixated using TiRobot navigation combined with ankle arthroscopy. Time for fracture reduction assisted by intraoperative arthroscopy, time for internal fixation assisted by TiRobotic navigation, fracture union time and complications were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used at the last follow-up to evaluate the functional outcomes.Results:All the operations were finished within 2 hour. The primary screw placement succeeded in all. The time for fracture reduction assisted by intraoperative arthroscopy averaged 52.8 min (from 43 to 66 min) and the time for internal fixation assisted by TiRobotic navigation 43.6 min (from 33 to 55 min). All the patients were followed up for an average 13.3 months(from 12 to 15 monhs). They obtained bony union within 3 months. One patient developed traumatic subtalar arthritis with mild pain and was treated conservatively. None of the patients had complications like incision infection or talus necrosis. The average AOFAS ankle-hindfoot score was 91.0 points (from 83 to 94 points) at the last follow-up.Conclusion:In the reduction and internal fixation of Hawkins type Ⅱ talus neck fracture, TiRobot navigation combined with ankle arthroscopy shows advantages of minimal invasion, accurate reduction and screw placement, and limited complications, leading to fine short-term functional outcomes.

Objective:To analyze the correlation between the posterior malleolus fracture and fixation and the rotational stability of the ankle and to explore the surgical indications for posterior malleolus fracture aiming to provide the theories for the diagnosis and treatment of disorder.Methods:Twenty fresh frozen cadaver specimens were selected. Further, the extent of the tibial insertion of the posterior inferior tibiofibular ligament (PITFL) and inferior transverse tibiofibular ligament (ITTFL) complex was dissected and measured. Based on the tibial insertion of the ligament complex, the model for the supination-external rotation degree 3 ankle fracture with a posterior malleolar fragment and syndesmosis diastasis was created. Moreover, the area threshold of the posterior tibial insertion of posterior malleolus fracture was biomechanically assessed. The difference of the antirotating ability of the ankle-stiffness between simple posterior malleolus fixation and simple syndesmotic fixation was analyzed statistically.Results:The PITFL and ITTFL were presented in all specimens with relatively broad in PITFL tibial insertion. The PITFL was attached to the posterolateral tibia. The distance between the highest point of the tibial insertion and the articular line was 45.2±5.6 mm, while the ITTFL was attached to the posterior distal tibia. The distance between the highest point of the tibial insertion and the articular line was 5.5±1.0 mm. The width of the tibial insertion of the PITFL and ITTFL complex decreased as the distance from the joint line increased. Biomechanical analysis showed that the threshold of posterior area of posterior malleolus fracture was 1/4S. The stiffnesses of posterior malleolus fixation and syndesmosis stabilization were 0.264±0.080 N·m/° and 0.164 ± 0.061 N·m/°, respectively. The percentage of stiffness restored by posterior ankle fixation was 60.9%±10.2%, which was greater than that by syndesmosis stabilization 37.5%±7.9% ( t=17.09, P<0.001) . Conclusion:The surgical technique for posterior malleolus fracture should consider restoration of the axial and rotational stability of the ankle simultaneously. Posterior malleolus fracture fixation is recommended when the syndesmosis is unstable with the area ratio of posterior tibial insertion of posterior malleolus fracture greater than or equal to 1/4. Syndesmotic fixation is proposed to restore and maintain the rotational stability of the ankle when the syndesmosis is unstable with the area ratio less than 1/4. Regardless of the area ratio, the surgical indications for stable syndesmosis depend on the impact of the posterior malleolus fracture on the axial stability of tibiotalar joint, on the involved articular surface area and on the displacement degree of posterior malleolus fragment.

Objective:To explore the effect of behavioral training of creative art therapy(CAT) on interpersonal communication in teenagers.Methods:Eighty teenagers were randomly divided into study group( n=40) and control group( n=40).The study group was received the behavioral training of CAT (12 times, each activity lasts for 120 min), and the control group did not take part in the behavioral training of CAT.The two groups were measured with self-esteem scale(SES), shyness scale(SS) and social anxiety scale for children(SASC) before and after behavior training.SPSS 17.0 software was used for statistical analysis, and t-test variance analysis and Mann-Whitney U test were used to compare the differences between groups or within groups. Results:Before and after behavioral training, changes in the SES total score (7.00(5.00, 9.75) vs 1.00(0, 2.00)), the SS total score (7.00(6.00, 12.75) vs 2.00(1.00, 3.00)), the SASC total score (5.00(2.00, 8.75) vs 0(0, 1.00)) and two factor scores (3.00(0.25, 5.00) vs 1.00(0, 1.00), 2.00(1.00, 4.00) vs 0(0, 1.00))in the study group were obviously higher than those in the control group( Z=-7.347, -7.338, -5.841, -4.122 and -5.393, all P<0.05).The score differences of the SASC total score ((7.19±3.82) vs (3.21±3.04)) and two factor scores ((4.00±2.23) vs (1.68±2.05), 3.00 (1.00, 5.00) vs 2.00 (0, 2.00)) of girls were significantly higher than those of boys in the study group ( t=-3.611, -3.398, Z=-2.111, P=0.001, 0.002, 0.035). Conclusion:Behavioral training of CAT can improve teenagers' self-esteem, relieve their shyness and social anxiety, as well as promote their interpersonal communication.

Objective: Understanding mental health status of students with learning disabilities in Beijing to provide a basis for mental health promotion of students with learning disabilities. Methods: By means of random cluster sampling, 5 787 enrolled students in grade one and grade two of 11 public junior middle schools in Beijing were selected as the survey subjects. A self designed questionnaire was used to investigate the students’ learning disabilities and mental health status through anonymous self filling. Results: About 11.6% students self reported learning disabilities. The proportions of students with learning difficulty in mathematical reasoning and calculation were higher, 44.1% and 40.7% respectively. The reported rate of mental health problems was 38.3%. The top four of the 10 symptoms were obsessive compulsive symptoms, learning pressure, emotional instability and anxiety(2.19±0.77)(2.17±0.99)(2.09±0.90)(2.07±1.08). Compared with students without learning disabilities, students with self reported learning disabilities had poorer mental health status(OR=1.47), and learning disabilities were related to most factors of mental health. Different types of learning disabilities were associated with different mental health factors. Conclusion Mental health problems of students with learning disabilities are higher than that of students without learning disabilities. It is necessary to strengthen the mental health support for students with learning disabilities and improve their mental health.
