Objective: This study aimed to explore the correlation between balance function and core muscle activation in patients with adolescent idiopathic scoliosis (AIS), compared to healthy individuals. Methods: A total of 24 AIS patients and 25 healthy controls were recruited. The limits of stability (LOS) test were conducted to assess balance function, while surface electromyography was used to measure the activity of core muscles, including the internal oblique, external oblique, and multifidus. Diaphragm thickness was measured using ultrasound during different postural tasks. Center of pressure (COP) displacement and trunk inclination distance were also recorded during the LOS test. Results: AIS patients showed significantly greater activation of superficial core muscles, such as the internal and external oblique muscles, compared to the control group (p < 0.05). Diaphragm activation was lower in AIS patients during balance tasks (p < 0.01). Although no significant difference was observed in COP displacement between the groups, trunk inclination was significantly greater in the AIS group during certain tasks (p < 0.05). Conclusion These findings suggest distinct postural control patterns in AIS patients, highlighting the importance of targeted interventions to improve balance and core muscle function in this population.

Objective: To investigate the correlation between sleep fragmentation and body composition/blood pressure in female students of middle school, so as to provide theoretical guidance for preventing health risks associated with sleep fragmentation. Methods: From September 2022 to December 2023, 505 female students aged 12-15 years in Nanyang City were selected through stratified cluster random sampling and conducted Pittsburgh Sleep Quality Index(PSQI) survey. Participants were divided into Q 1- Q 4 groups based on sleep fragmentation index (SFI) quartiles. Body composition and blood pressure measurements were measured by adopting body composition analyzer and traditional mercury sphygmomanometer, and data were analyzed using χ 2 tests and linear regression. Results: Significant intergroup differences for Q 1- Q 4 were observed with increasing SFI levels for body mass index(BMI), fat percentage, muscle mass, bone mass, trunk fat percentage, systolic blood pressure, diastolic blood pressure, and PSQI total scores ( F =15.25,7.33,8.38,5.97,11.24,16.85,6.87,15.73, all P <0.05). SFI showed positive correlations with BMI, fat percentage, trunk fat percentage, and blood pressure( β =0.37,0.45,0.34,0.42,0.38), but negative correlations with muscle mass and bone mass( β =-0.35,-0.48) (all P <0.05). The χ 2 trend test revealed a significant increase in hypertension detection rates with elevated SFI ( χ 2=42.75, P <0.05). The χ 2 testing demonstrated statistically significant differences in hypertension incidence among different quartiles groups ( χ 2=14.16, P <0.05). After adjusting the significance level, hypertension incidence differences remained significant between Q 1and Q 4 ( χ 2=10.77), Q 2 and Q 4 groups ( χ 2=6.28) (both P <0.008 3). Conclusions Sleep fragmentation correlates significantly with body composition and blood pressure indicators in female students of middle school. Implementing sleep fragmentation interventions is essential for safeguarding female students health in middle school.

Amber and subfossil resins are subjects of interdisciplinary research across multiple fields. However, due to their diverse origins and complex compositions, different disciplines vary in their definitions and functional interpretations. In traditional Chinese medicine(TCM), amber has been utilized as a medicinal material since ancient time, with extensive historical documentation. However, its classification, provenance, and nomenclature remain ambiguous, and authentic medicinal amber artifacts are exceedingly rare. This study employed Fourier-transform infrared spectroscopy(FTIR) to characterize amber and subfossil resins from various geological sources and commercially "medicinal amber". Additionally, historical literature and market surveys were analyzed to explore their provenance, composition, and functional attributes. The results indicate that amber and subfossil resins from different sources and with different compositions exhibit distinct fingerprint characteristics in the FTIR spectral range of 1 800-700 cm~(-1). "Medicinal amber" available in the market primarily consists of subfossil or modern resins, significantly differing in composition and structure from geological amber. This study highlights the importance of interdisciplinary research on amber identification and resource management. It is essential to establish a systematic database of amber and subfossil resin characteristics and integrate modern analytical techniques to enhance research on their composition, pharmacological mechanisms, and potential therapeutic effects, thereby promoting the standardized utilization of amber resources and advancing the modernization of TCM.

OBJECTIVE: To compare clinical effect of anterior tibial plateau fracture line and anterior tibial fenestration reduction in treating anterolateral tibial plateau column fracture combined with posterior lateral column collapse. METHODS: Fifty-two patients with Schatzker typeⅡ tibial plateau anterolateral column fracture combined with posterolateral column collapse admitted from January 2016 to December 2021 were retrospectively analyzed and divided into two groups according to fracture reduction methods. There were 27 patients in fracture line group, including 19 males and 8 females, aged from 26 to 62 years old with an average of (43.2±11.4) years old;the time from injury to operation ranged from 4 to 8 days with an average of (5.8±1.5) days;treated with reduction and internal fixation via fracture line of lateral platform front. There were 25 patients in fenestrate group, including 13 males and 12 females, aged from 22 to 69 years old with an average of (40.8±11.1) years old;the time from injury to operation ranged from 4 to 8 days with an average of (6.0±1.4) days;treated with tibial fenestration reduction and internal fixation. The amount of bone graft, operation time, fracture healing time and complications were compared between two groups. Posterior slope angle (PSA) and posterior slope angle of the lateral tibial plateau was compared before surgery, 2 days and 6 months after surgery. The knee function was evaluated by Hospital for Speical Surgery (HSS) at 2 days and 6 months after surgery, respectively. Fracture reduction was evaluated by Rasmussen anatomic score of knee joint. RESULTS: Both of group were followed up from 12 to 24 months (16.0±3.4) months. No redisplacement of fracture, internal and external inversion deformity of knee joint, or instability of knee joint were found between two groups during follow-up. In fracture line group, 1 patient occurred wound fat liquefaction and 2 patients occurred lower limb intermuscular venous thrombosis occurred. In fenestration group, 1 patient occurred joint stiffness, 1 patient occurred lower limb intermuscular venous thrombosis, and 1 patient occurred superficial wound infection;there were no significant difference in complications between two groups (P>0.05). Bone graft volume, operative time and fracture healing time in fracture line group were (3.6±2.3) cm³, (123.4±18.2) min and (13.8±1.8) weeks, while in feneplast group were (4.8±1.8) cm³, (135.5±22.5) min and (15.2±2.0) weeks, respectively;the difference between two groups was statistically significant (P<0.05). The collapse depth of lateral platform articular surface at 2 days and 6 months after surgery were (0.8±0.1) and (0.9±0.1) mm in fracture line group, which were lower than those in fenestration group (0.9±0.1) and (1.1±0.1) mm, respectively (P<0.05). After 2 days and 6 months, , PSA in fracture line group were (9.4±1.5) ° and (10.1±1.9) °, respectively, which were lower than those in fenestration group (10.5±1.5) ° and (11.3±1.9) ° (P<0.05). Rasmussen anatomical scores in fracture line group at 2 days and 6 months were 16(16, 18) and 16(14, 16) points, respectively, which were better than those in fenestrated group (16, 16) and 14(14, 16) points (P< 0.05). The collapse depth, PSA and Rasmussen anatomical score between two groups were better than those before surgery (P<0.05). There was no significant difference in HSS score between two groups at 2 days after surgery (P>0.05). At six months after surgery, HSS score in fracture line group (86.7±3.6) was higher than that in fenestration group (84.1±3.91) (P<0.05). HSS score at 6 months after surgery was better than that at 2 days after surgery (P<0.05). CONCLUSION Both anterior tibial plateau fracture line and anterior tibial fenestration could be used to treat anterolateral tibial plateau column fracture with posterior lateral column collapse. Compared with fenestration group, transfracture line group had advantages of less intraoperative bone grafting, shorter operative time, shorter fracture healing time, better articular surface reduction effect and better knee functional recovery.

OBJECTIVE: To explore the early clinical efficacy of a three-stage external treatment with traditional Chinese medicine (TCM) in the treatment of talar bone contusion caused by acute ankle sprain. METHODS: A retrospective analysis was performed on 360 patients with primary lateral ankle sprain admitted from September 2021 to July 2024. Patients with talar bone contusion were selected based on MRI examination, and 73 cases were finally included. According to different treatment methods, they were divided into the observation group and the control group. The observation group consisted of 35 cases, including 16 males and 19 females, aged 24 to 37 years old with an average of (30.34±2.68) years old, and received the three-stage external TCM treatment combined with the "POLICE" protocol. The control group included 38 cases, including 18 males and 20 females, aged 24 to 35 years old with an average of (29.87±2.57) years old, and was treated with the "POLICE" protocol alone. The volume of bone marrow edema (BME) area shown by MRI before treatment and 6 weeks after treatment was measured using 3D Slicer software, and the BME improvement rate was calculated. The "Figure of 8" measurement method was used to assess ankle swelling before treatment and at 1 and 3 weeks after treatment. The visual analogue scale (VAS) was used to evaluate ankle pain before treatment and at 1 and 6 weeks after treatment. At 6 weeks after treatment, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Karlsson ankle function score system were used to evaluate the improvement of ankle function. RESULTS: A total of 73 patients with talar bone contusion caused by ankle sprain completed the 6-week follow-up. At 6 weeks after treatment, the BME improvement rate in the observation group was (39.18±0.06)%, which was higher than (26.75±0.03)% in the control group, with a statistically significant difference (P<0.05). After 1 week of treatment, the VAS score in the observation group was (2.89±0.72) points, lower than (3.37±0.79) points in the control group, and the difference was statistically significant (P<0.05). The ankle swelling degree in the observation group was (50.20±3.19) cm, lower than (52.00±3.60) cm in the control group, with a statistically significant difference (P<0.05). After 3 weeks of treatment, there was no statistically significant difference in ankle swelling between the two groups. At 6 weeks after treatment, there was no statistically significant difference in VAS scores between the two groups. At 6 weeks after treatment, the AOFAS ankle-hindfoot score and Karlsson score in the observation group were (87.43±4.18) and (82.77±5.93) points, respectively, which were higher than (82.92±4.87) and (76.45±6.85) points in the control group, with statistically significant differences (P<0.05). According to the AOFAS ankle-hindfoot score, 8 cases were excellent and 27 cases were good in the observation group;2 cases were excellent, 33 cases were good, and 3 cases were fair in the control group. The difference between the two groups was statistically significant (χ²=7.089, P=0.029). CONCLUSION The three-stage external TCM treatment combined with the "POLICE" protocol has a significant early clinical efficacy. It can significantly reduce ankle pain and swelling in patients with bone contusion caused by acute lateral ankle sprain, promote the absorption of bone marrow edema, and accelerate the recovery of ankle function.
