Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

The core pathogenesis of attention deficit hyperactivity disorder （ADHD） lies in deficiency， stasis and stagnation. Deficiency arises from kidney essence depletion and spleen dysfunction in transportation and transformation， leading to inadequate nourishment of the marrow sea. Stasis caused by qi deficiency leads to obstruction in channels and collaterals， resulting in obstructed marrow transport. Stagnation is associated with the excess of the five minds transforming into fire， which scorches the brain orifices and leads to loss of control over marrow utilisation. Based on this， a "supplementation-unblocking-regulation" therapeutic approach is proposed. For deficiency， the focus is on supplementing kidney and fortifying spleen， and replenishing the marrow sea. For stasis， the priority is to unblock and open the orifices， and clear the marrow channels. For stagnation， the core is to clear fire and contain the mind， regulate and restore vital activity. In clinical practice， it is necessary to identify the primary and secondary pathogenic mechanisms and apply dynamic， combined treatment， integrating Chinese herbal medicine， acupuncture， and guiding exercises throughout the process， aiming to provide a reference for the diagnosis and treatment of ADHD with traditional Chinese medical.

Objective To investigate the effects of SAC/VAL on myocardial fibrosis and miR-21 expression in rats induced by AAC.Methods A total of 72 SPF SD male rats were randomly di-vided into sham operation group,AAC group,low-and high-dose SAC/VAL groups,high-dose SAC/VAL+agomiR-NC group,and high-dose SAC/VAL+miR-21 agomiR group,with 12 rats in each group.Echocardiography was used to test cardiac function.HE staining and Masson staining were applied to observe the pathological changes in myocardial tissues and myocardial tissue fi-brosis,respectively.Immunohistochemical assay was employed to detect the expression of α-SMA and COL-l in myocardial tissue.Real-time fluorescence quantitative polymerase chain reaction was conducted to detect miR-21 level.Results Compared with the sham operation group,the AAC group had thicker and broken myocardial fibers in disordered arrangement,hypertrophic myocar-dial cells with condensed and deeply stained nuclei,and extensive infiltration of inflammatory cells,and obvious myocardial fibrosis,increased LVEDD and LVESD values,and up-regulated miR-21,α-SMA and COL-1 expression,but decreased LVEF and LVFS levels(P＜0.05).Low-and high-dose SAC/VAL treatment resulted in well-arranged less broken myocardial fibers in uniform distribution,relatively normal myocardial cells,less inflammatory cell infiltration,and reduced severity of myocardial fibers,lower LVEDD and LVESD values,decreased miR-21,α-SMA and COL-1 levels,but increased LVEF and LVFS levels when compared to the AAC group(P＜0.05).When compared to the high dose SAC/VAL+agomiR NC group,the high-dose SAC/VAL+miR-21 agomiR group had disorderly-arranged myocardial fiber with thickening and breakage,aberrant myocardial cells,obvious infiltration of inflammatory cells,and intensified my-ocardial fibrosis,higher LVEDD and LVESD values and miR-21,α-SMA and COL-1 expression levels,and lower LVEF and LVFS levels[7.11±0.45 mm vs 6.05±0.38 mm,P＜0.05;5.58±0.35 mm vs 4.01±0.28 mm,P＜0.05;2.57±0.14 vs 0.98±0.10,P＜0.05;0.62±0.06 A vs 0.41±0.04 A,P＜0.05;0.79±0.08 A vs 0.53±0.05 A,P＜0.05;(58.26±2.61)％vs(80.24±2.87)％,P＜0.05;(24.52±1.03)％vs(33.72±1.25)％,P＜0.05].Conclusion SAC/VAL inhibits AAC-induced myocardial fibrosis in rats,which is related to its regulation of miR-21 expression.

Objective:To compare the clinical effects of pedicle screw internal fixation under different approaches for the treatment of asymptomatic thoracolumbar fractures.Methods:Retrospective analysis was conducted to collect data from 83 patients with asymptomatic thoracolumbar fractures treated with pedicle screw internal fixation at Handan Central Hospital from January 2023 to December 2023. Based on different surgical approaches, 40 patients who underwent regular percutaneous approach surgery were included in the conventional approach group, and 43 patients who underwent modified Wiltse approach surgery were included in the modified approach group. The perioperative indexes and postoperative complications of the two groups were statistically analyzed. The visual analogue score (VAS) was compared before operation, 1 month after operation and 3 months after operation. The anterior vertebral height, Cobb angle and fracture healing factors were compared before operation and 3 months after operation.Results:The surgical time, incision length and intraoperative fluoroscopy frequency of the modified approach group were all lower than those of the conventional approach group: (65.75 ± 7.16) min vs. (74.28 ± 6.85) min, (6.75 ± 0.42) cm vs. (9.58 ± 0.50) cm and (9.22 ± 1.24) times vs. (21.03 ± 2.45) times, with statistically significant differences ( P<0.05). The total incidence of postoperative complications in the modified approach group was 9.30% (4/43), while the total incidence of postoperative complications in the conventional approach group was 15.00% (6/40), with no statistically significant difference ( P>0.05). The VAS of the modified approach group was lower than that of the conventional approach group at 1 and 3 months after surgery: (3.05 ± 0.82) points vs. (3.86 ± 0.85) points and (1.62 ± 0.32) points vs. (2.24 ± 0.54) points, with statistically significant differences ( P<0.05). Three months after surgery, the height of the anterior vertebral edge, serum type Ⅰ procollagen N-terminal propeptide and platelet-derived growth factor in the modified approach group were significantly higher than those in the conventional approach group: (72.96 ± 9.27)% vs. (67.58 ± 9.02)%, (174.36 ± 16.75) μg/L vs. (146.24 ± 15.86) μg/L, (250.28 ± 14.62) U/L vs. (241.20 ± 12.75) U/L, the Cobb angle was lower than that of the conventional approach group: (10.15 ± 1.32)° vs. (12.20 ± 1.86)°, with statistically significant differences ( P<0.05). Conclusions:The modified Wiltse approach and percutaneous approach pedicle screw internal fixation are safe and effective in treating asymptomatic thoracolumbar fractures; but compared to the latter, the former has a shorter surgical time, fewer intraoperative fluoroscopy sessions, and less postoperative pain. It has better effects in improving the height of the anterior edge of the injured vertebra, Cobb angle recovery, and fracture healing factors.

Objective:To analyze the correlation between near work, screen time, outdoor time and myopia in children based on objective monitoring technology and to explore the influencing factors related to myopia in children.Methods:A cross-sectional study was conducted.From October 2022 to March 2023, the purposive sampling method was used to select 596 children in Grade 2 and Grade 3 from two primary schools in Shandong Province as study subjects.Eye-Monitor technology of eye-use behavior based on artificial intelligence was used to quantify parameters of near work, screen time and outdoor time.The eye-use behavior parameters were compared within each subject and between non-myopic and myopic children on weekdays and weekends.A multivariate binary logistic regression model was constructed to analyze the influencing factors related to myopia.The study protocol was approved by the Medical Ethics Committee of the Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine (No.HEC-HY-2022023KY).Written informed consent was obtained from the legal guardian of each subject.Results:For each subject, the proportion of near work time on weekdays was greater than on weekends, the proportion of time spent looking at cell phones, computer screens, and outdoor activities was smaller, the duration of single continuous near eye use was longer, the tilt angle of the head in sitting position was greater, and the light intensity was stronger, showing statistically significant differences ( t=19.427, -9.964, -5.916, -10.470, 2.211, 2.898, 15.061; all P<0.05).During weekdays, compared with the non-myopia group, the myopia group had longer total near work duration, longer single continuous near eye use duration, shorter outdoor activity duration, closer eye use distance, larger proportion of near work time, and smaller proportion of outdoor activity time, showing statistically significant differences (all P<0.05).During weekends, compared with the non-myopia group, the myopia group had longer time spent looking at cell phones and computer screens, shorter outdoor activity time, greater proportion of time spent looking at cell phones and computer screens, and smaller proportion of outdoor activity time, with statistically significant differences (all P<0.05).During weekdays, after adjusting for confounding factors, longer single continuous near eye use duration ( OR=1.138, 95% CI: 1.086-1.192, P<0.001) was the risk factor for myopia, and longer working distance ( OR=0.906, 95% CI: 0.847-0.970, P=0.004) and longer outdoor activity time ( OR=0.127, 95% CI: 0.023-0.703, P=0.018) were protective factors for myopia.During weekends, after adjusting for confounding factors, longer time spent on looking at cell phone screens ( OR=2.437, 95% CI: 1.460-4.068, P<0.001) and longer time spent on looking at computer screens ( OR=2.260, 95% CI: 1.283-3.979, P=0.005) were risk factors for myopia, and longer outdoor activity time ( OR=0.624, 95% CI: 0.416-0.934, P=0.022) was the protective factor for myopia. Conclusions:The eyes with continuous near work, prolonged use of smartphone and computer screens, closer eye use distance, and less time spent outdoors have been confirmed to be significantly correlated with myopia based on objective monitoring data.When formulating intervention measures for myopia prevention and control in children, it is advocated to further pay attention to control the distance and duration of near work on weekdays and strengthen screen time management on weekends.
