BackgroundIn recent years， the incidence of non-suicidal self-injury （NSSI） behaviors among adolescents has been increasing annually. Self-esteem and alexithymia are strongly associated with NSSI behaviors， and alienation is closely linked to both self-esteem and alexithymia. However， there is limited research on the relationship between alienation and NSSI behaviors among adolescents in China. ObjectiveTo analyze the relationship between alienation and NSSI behaviors among adolescents， and to explore the factors influencing NSSI behaviors in this population， so as to provide insights for the prevention and treatment of NSSI behaviors in adolescents. MethodsAdolescents admitted to the Department of Psychiatry and Psychology at the 923^rd Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from September 1， 2021 to March 1， 2023， who met the diagnostic criteria for NSSI in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， were selected as the study group （n=60）. Concurrently， middle school students from Nanning were recruited as the control group （n=60）. Participants were assessed using Adolescent Self Harm Scale （ASHS）， Rosenberg Self-Esteem Scale （RSES）， Toronto Alexithymia Scale （TAS） and Adolescent Students′ Alienation Scale （ASAS）. Pearson correlation analysis was employed to examine the relationships between scale scores in the study group， and Logistic regression analysis was used to identify the influencing factors of NSSI behaviors among adolescents. ResultsThe RSES score of the study group was significantly lower than that of the control group （t=-7.033， P<0.01）. The TAS and ASAS scores of the study group were significantly higher than those of the control group （t=5.591， 8.124， P<0.01）. The ASHS score was negatively correlated with RSES score （r=-0.410， P<0.01） and positively correlated with ASAS score （r=0.555， P<0.01）. The RSES scores of the study group were negatively correlated with TAS and ASAS scores （r=-0.317， -0.590， P<0.05 or 0.01）. Logistic regression analysis showed that being female （OR=0.714， 95% CI： 0.042~0.709） was a protective factor for NSSI behaviors among adolescents， while high alienation （OR=1.028， 95% CI： 1.013~1.043） and residing in rural areas （OR=6.692， 95% CI： 2.038~21.967） were risk factors for NSSI behaviors among adolescents. ConclusionAlienation was positively correlated with NSSI behaviors in adolescents. Female adolescents had a lower risk of NSSI behaviors， while those with higher levels of alienation or residing in rural areas were more prone to NSSI behaviors. ［Funded by Self-financed Scientific Research Project of the Health Commission of Guangxi Zhuang Autonomous Region （number， Z20210656）； Self-financed Scientific Research Project of the Health Commission of Guangxi Zhuang Autonomous Region （number， Z-A20231057）］

Tufted angioma (TA) is a rare vascular endothelial cell tumor that often occurs in infants and early childhood and is rare in adults. There are currently no unified treatment guidelines, and treatment options for children with TA are limited and challenging. This report introduces a case of a child diagnosed with superficial TA in the left popliteal fossa. Topical 0.1% sirolimus cream was given in the early stage and combined with pulsed dye laser treatment in the later stage. The child’s skin lesions recovered well. The author reviews relevant literature reports to summarize the treatment of TA in children and provide relevant ideas and new options for the diagnosis and treatment of the disease.

Objective To explore the clinical efficacy of arthroscopy combined with cubital tunnel expansion and plasty in the treatment of patients with elbow osteoarthritis and cubital tunnel syndrome.Methods A total of 101 patients with elbow osteoarthritis and cubital tunnel syndrome who were admitted to the Department of Orthopedics,Cangzhou Hospital of Integrated TCM-WM Hebei from September 2020 to August 2023 were selected as the research subjects.According to different surgical methods,the patients were divided into an observation group(n=51)and a control group(n=50).The surgical method in the observation group was arthroscopy combined with cubital tunnel expansion and plasty,and the surgical method in the control group was conventional cubital tunnel expansion and plasty.The operation time,intraoperative blood loss,length of hospital stay,and complications were observed and recorded for both groups.The mayo elbow performance score(MEPS)was used to assess elbow function,the activities of daily living(ADL)scale was used to evaluate daily living ability,and the visual analogue scale(VAS)was used to assess pain levels preoperatively and at 6 months postoperatively.Elbow range of motion,including pronation,supination,and flexion-extension,was measured using a goniometer.Nerve recovery was evaluated by measuring compound muscle action potential(CMAP)of the abductor digiti minimi,ulnar nerve conduction velocity(NCV),and motor evoked potential latency(MEPLP)using a Keypoint electromyography device.Results The operation time and length of hospital stay in the observation group were significantly shorter than those in the control group,and the intraoperative blood loss and complications were significantly less than those in the control group(P＜0.05).Before operation,there were no statistically significant differences in MEPS scores,ADL scores and VAS scores between the observation group and the control group(P＞0.05);6 months after operation,the MEPS scores and ADL scores of patients in the observation group were signifi-cantly higher than those in the control group,and the VAS scores were significantly lower than those in the control group(P＜0.05).Before operation,there were no statistically significant differences in pronation,supination and flexion-extension between the observation group and the control group(P＞0.05);6 months after operation,the pronation,supination and flexion-extension of patients in the two groups were significantly higher than those before operation(P＜0.05),but there were no statistically significant differences in pronation,supination and flexion-extension between the observation group and the control group(P＞0.05).Before operation,there were no statistically significant differences in CMAP,NCV and MEPLP between the observation group and the control group(P＞0.05);6 months after operation,the CMAP and NCV of patients in the observation group were significantly higher than those in the control group,and the MEPLP ratio was significantly lower than that in the control group(P＜0.05).Conclusion Conventional cubital tunnel expansion and plasty and arthroscopy combined with cubital tunnel expansion and plasty can improve the range of motion of the elbow in patients with elbow osteoar-thritis and cubital tunnel syndrome,but the latter features less damage and faster recovery,is better in improving elbow function and daily living ability,reducing pain,and adjusting electromyographic examination indicators,and has fewer complications.

ObjectiveTo construct a traditional Chinese medicine （TCM） syndrome diagnosis and prescription model for coronary heart disease with the improved Transformer algorithm. MethodTaking the syndrome elements of coronary heart disease as key links， the model was constructed based on the clinical diagnosis and treatment principle of "symptoms-syndrome elements-syndrome-treatment method-prescription-medicine （dose）". The basic logic of improved Transformer algorithm was constructed with multi-head attention mechanism， compound term vector and dropout， in order to form the model with functions of TCM syndrome elements judgment， syndrome diagnosis， prescription recommendation. After the model was constructed， it was trained by 8 030 cases. And 100 cases with TCM prescriptions were randomly selected for testing， and the model output prescriptions were compared with those of clinicians for qualitative evaluation of the model. ResultThe improved Transformer with multi-head attention improved the accuracy of the model. The model was consistent with clinicians in the judgment of main syndromes and the selection of prescriptions. Whereas there was a certain room for improvement in the addition and subtraction of medicines. ConclusionThe improved Transformer model can improve the accuracy and stability of output， which is an embodiment of the intelligent development of TCM.

The integrity of lysosomes is of vital importance to survival of tumor cells. We demonstrated that LW-218, a synthetic flavonoid, induced rapid lysosomal enlargement accompanied with lysosomal membrane permeabilization in hematological malignancy. LW-218-induced lysosomal damage and lysosome-dependent cell death were mediated by cathepsin D, as the lysosomal damage and cell apoptosis could be suppressed by depletion of cathepsin D or lysosome alkalization agents, which can alter the activity of cathepsins. Lysophagy, was initiated for cell self-rescue after LW-218 treatment and correlated with calcium release and nuclei translocation of transcription factor EB. LW-218 treatment enhanced the expression of autophagy-related genes which could be inhibited by intracellular calcium chelator. Sustained exposure to LW-218 exhausted the lysosomal capacity so as to repress the normal autophagy. LW-218-induced enlargement and damage of lysosomes were triggered by abnormal cholesterol deposition on lysosome membrane which caused by interaction between LW-218 and NPC intracellular cholesterol transporter 1. Moreover, LW-218 inhibited the leukemia cell growth
