Diannan Su's bone-setting school is one of the orthopedic schools of traditional Chinese medicine(TCM),and Su Caichen,a famous bone-setting physician in Diannan,is the key figure of Diannan Su's bone-setting school.This paper systematically summarized Su Caichen's bone-setting academic thoughts of"adaptation","harmonization"and"recovery",presented his core bone-setting concepts of"original traumatic chamber","bone-setting prior to activating blood and vessles,bone-setting together with soothing tendons and then fracture healing naturally after the removal of stasis",and introduced his five kinds of bone-setting manipulations for treating the common upper limb fractures in detail,namely shaking and pushing manipulations for distal radius fracture,floating manipulations for fracture of both ulna and radius,five-step manipulations for supracondylar fractures of humerus,staging manipulations for humeral shaft fracture,and degloving manipulations for proximal humeral fractures complicated with shoulder dislocation.Su Caichen's bone-setting academic thoughts,bone-setting concepts and his specific TCM bone-setting manipulations have constructed the academic and theoretical system of Diannan Su's bone-setting school,which will provide an approach for TCM treatment of orthopedic diseases,and will promote the inheritance and development of the specific TCM orthopedic schools.

Objective: To investigate the dynamic changes in oral health-related quality of life (OHRQoL) and self-esteem (SE) across different stages of adolescent orthodontic treatment and the influence of psychosocial factors, thereby providing scientific evidence for the clinical development of individualized treatment protocols that integrate both functional correction and psychological intervention. Methods : This study was reviewed and approved by the medical ethics committee, and informed consent was obtained from patients. A cross-sectional design was employed to randomly select 355 adolescent patients with malocclusion (133 pre-treatment, 112 during treatment, and 110 post-treatment) who received care at the Department of Stomatology, Renmin Hospital of Wuhan University in April 2025. The Oral Health Impact Profile (OHIP)-14 was used to assess OHRQoL levels, the Global Self-Esteem Scale (GSE) was used to evaluate SE levels, and an additional questionnaire on dental appearance-related psychosocial aspects was administered. Kruskal-Wallis tests were used to compare differences between treatment stage groups, followed by Dunn post hoc tests. Spearman correlation analysis was employed to assess the associations between variables, including orthodontic treatment stages, OHRQoL, and SE, as well as SE and dental appearance-related psychosocial aspects. Results : OHRQoL and its four dimensional scores showed significant differences across different stages of orthodontic treatment. Specifically, the total OHIP-14 score showed no significant difference between pre-treatment and during treatment [12.0 (7.0, 18.0) vs. 13.0 (9.0, 17.0)], but significantly decreased to 4.0 (0.8, 11.0) post-treatment (P<0.001). The total scores for physical pain and discomfort dimension and physical disability dimension demonstrated a pattern of during treatment > pre-treatment > post-treatment (P<0.05). The total scores for handicap dimension showed no significant difference between pre-treatment and during treatment, but post-treatment scores were significantly lower than both pre-treatment and during treatment levels (P < 0.001). The total scores for psychological discomfort dimension showed a significant decreasing trend across treatment stages (P<0.001). The total GSE score showed significant differences only between pre-treatment and during treatment [18.0 (12.0, 23.0) vs. 13.5 (9.3, 20.8), P=0.014], with recovery to 14.0 (12.0, 18.0) post-treatment. Different treatment stages showed a moderate negative correlation with total OHIP-14 score (r=-0.362, P<0.001) and a weak negative correlation with total GSE score (r=-0.104, P=0.049). The appearance satisfaction index showed a significant increasing trend across treatment stages (P<0.001), while being teased about teeth and hiding teeth and avoiding smiling index significantly decreased (both P<0.001). Being teased about teeth index (r=0.349, P<0.001) and hiding teeth and avoiding smiling index (r=0.412, P<0.001) were significantly correlated with total GSE score. Conclusion Adolescents undergoing orthodontic treatment experience a significant improvement in quality of life, with self-esteem levels notably increasing during the mid-treatment phase and a continuous reduction in negative psychosocial experiences related to dental appearance. This suggests that orthodontists should prioritize psychological support and social adaptation guidance throughout the treatment process, with consistent attention to changes in patients’ self-esteem.

Objective To evaluate the prevention and control effectiveness of four major chronic diseases in Youyang County, and find the weak link of prevention and control, and to provide theoretical support for improving prevention and control strategies. Methods Based on the death data of permanent residents from 2012 to 2020 extracted from the cause-of-death registration and reporting system of Youyang County, a statistical analysis was conducted using SPSS19.0. The annual percentage change (APC) was tested by t-test. Results From 2012 to 2020, the mortality rate of and the standardized mortality rate of the four major chronic diseases and the premature mortality rate of diabetes in males showed an increasing trend (APC was 3.05%, 1.82% and 27.12%, respectively, P < 0.05). The mortality rate of the four chronic diseases in females increased (APC was 2.53%, P < 0.05), while the proportion of premature death of the four chronic diseases and the probability of premature death of cardiovascular and cerebrovascular diseases in females decreased (APC was -2.37%, -5.73%, P < 0.05). The standardized mortality rate and premature death rate of the four major chronic diseases were higher in males than those in females. The mortality rate of the four major chronic diseases and the premature death rate of diabetes in the whole population were on the rise (APC was 2.84% and 12.86%, P < 0.05). It was expected that the early death probability of the four major chronic diseases in Youyang County would be 12.65% in 2030, higher than the target value of 12.59% of ^“Healthy China 2030^”. Conclusion The future focus of Youyang County is to prevent and control malignant tumors and diabetes, especially to strengthen the prevention and control of male diabetes.

Thoracic anesthesia with spontaneous respiration represents a form of precision anesthesia meticulously customized to individual patients.Considering the more stringent requirements this anesthesia approach imposes on the regulation of respiratory function,the writing group of the"Consensus of Experts on the Management of Thoracic Anesthesia with Spontaneous Respiration"has formulated elaborate guidelines regarding indications and contraindications,preoperative evaluation,anesthesia implementation,common complications,and treatment strategies.This was accomplished by referencing relevant domestic and international literature and integrating it with actual clinical requirements.The objective is to standardize the rational application of this anesthesia method.

【Objective】 To analyze the clinical characteristics of serum vitamin K2 in children and its correlation with bone mineral density, so as to provide reference for the prevention of insufficient bone strength in children. 【Methods】 A total of 4 145 children who underwent serum vitamin K2 testing and physical examination at pediatric outpatient clinics of several municipal and county hospitals in Chongqing from January 2020 to March 2023 were retrospectively selected into this study for serum vitamin K2-related analysis.Further 844 school-age children who completed serum 25-(OH)D and lumbar bone densitometry measurements were screened to analyze the correlation between vitamin K2level and bone mineral density 【Results】 The overall serum vitamin K2 deficiency rate was 61.6% (2 553/4 145), and the difference in serum vitamin K2 deficiency rate between different age groups was statistically significant (χ²=39.364, P<0.05).The vitamin K2 level of children was significantly influenced by season and maternal education level (χ²=45.310,9.990, P<0.05).There were significant differences in age (Z=3.416), gender (χ²=9.218) and serum vitamin K2 deficiency rate (χ²=5.826) between normal bone mass development group and insufficient bone mass development group (P<0.05).Multivariate Logistic regression analysis suggested that vitamin K2 deficiency was an independent risk factor for insufficient bone mass development in school-age children (OR=1.37,95%CI:1.03 - 1.83, P=0.030). 【Conclusions】 There is a higher serum vitamin K2 deficiency rate among children, especially infants and school-age children.Decreased bone mineral density in school-age children may be associated with serum vitamin K2 deficiency.

Most of the CHD patients reveal string pulse, mainly due to damage of heart function, lowering of arterial compliance and increase of total peripheral resistance. The common pulse in patients of blood diseases reveal frequent, tiny, string and slippery characteristic, mostly due to the increase of compensatory pumping action of the heart, shortening of ejection time of the left heart, with better vessel compliance and hemorheology, low total peripheral resistance.
