In recent years， the incidence of depression among adolescents has increased significantly， becoming a serious global public health problem. There is a close relationship between adolescent depression and lipid metabolism abnormalities. However， the mechanisms underlying this association have not been fully elucidated. This article provides a review of the mechanisms and interventions linking adolescent depression and lipid metabolism abnormalities， aiming to offer new ideas for interventions in adolescent depression. Using computerized searches of the China National Knowledge Infrastructure （CNKI）， Wanfang Data， PubMed， and Web of Science， studies on the mechanisms and interventions related to adolescent depression and lipid metabolism were collected， with the search period extending up to October 10， 2025. Two researchers independently conducted literature screening and extracted basic information from the included studies. A total of 12 original studies were included. The results indicate that adolescent depression is associated with certain lipid metabolites. Neurobiological factors， immune inflammation， oxidative stress， and gut microbiota imbalance play important roles in this association. In addition， lipid metabolites such as omega-3 polyunsaturated fatty acids （ω-3 PUFAs） have a significant ameliorating effect on adolescent depression. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）； Shenzhen Science and Technology Program （number， 20210617155253001）］

The new generation of artificial intelligence technology,represented by deep learning,has emerged as a crucial driving force in the advancement of new drug research and development.This article creatively proposes a workflow named"Molecular Factory"for the design and optimization of drug molecules based on artificial intelligence technology.This workflow integrates intelligent molecular generation models,high-performance molecular docking algorithms,and accurate protein-ligand binding affinity prediction methods.It has been integrated as a core module into DrugFlow,a one-stop drug design software platform,providing a comprehensive set of mature solutions for the discovery and optimization of lead compounds.Utilizing the"Molecular Factory"module,we conducted the research of second-generation inhibitors against Menin that can combat drug resistance.Through the integration of computational and experimental approaches,we rapidly identified multiple promising compounds.Among them,compound RG-10 exhibited the IC50 values of 9.681 nmol/L,233.2 nmol/L,and 40.09 nmol/L against the wild-type Menin,M327I mutant,and T349M mutant,respectively.Compared to the positive reference molecule SNDX-5613,which has entered Phase Ⅱ clinical trials,RG-10 demonstrated significantly enhanced inhibitory activity against the M327I and T349M mutants.These findings fully demonstrate the unique advantages of the"Molecular Factory"technology in practical drug design and development scenarios.It can rapidly and efficiently generate high-quality active molecules targeting specific protein structures,holding significant value and profound implications for advancing new drug discovery.

Objective:To compare the clinical outcomes and complications of oblique lateral interbody fusion combined with bilateral pedicle screw fixation through intermuscular approach and posterior interbody fusion combined with bilateral pedicle screw fixation through intermuscular approach by channel for lumbar spinal stenosis.Methods:A retrospective study was conducted on 73 patients who underwent surgical treatment for lumbar spinal stenosis from Jun 2015 to Jun 2017, including 33 males and 40 females. The average age was 66.8±7.94 years (from 39-85 years). These diseases occured at L 3/4 in 5 patients and L 4/5 in 68 patients. Random according to the time of admission, 38 cases were treated with oblique lateral interbody fusion combined with bilateral pedicle screw fixation through intermuscular approach (oblique lateral fusion group), and 35 cases with posterior interbody fusion combined with bilateral pedicle screw fixation through intermuscular approach by channel (posterior fusion group). The clinical results, image data and complications were compared between the two groups. Results:All patients in both groups had operation performed smoothly. The operation time was 99±8.96 min in the oblique lateral fusion group and 96.8±9.57 min in the posterior fusion group, and there was no significant difference between the two groups. The intraoperative bleeding in the oblique lateral fusion group 80±24.72 ml was significantly less than that in the posterior fusion group 261±52.87 ml ( t=9.621, P<0.05). No incision infection occurred after surgery. The VAS score of lumbar incision 72h after operation in the oblique lateral fusion group 1.21±0.55 was significantly less than that in the posterior fusion group 1.70±0.86 ( t=3.723, P=0.028). The follow-up period lasted for 12-24 months, averagely 17.5±2.58 months. There was statistically significant difference between preoperative and postoperative in the two groups, whether it was the area of the foraminal canal or the area of the spinal canal. There wboth the foraminal area and the spinal canal area were enlarged. The intervertebral space height in the two groups recovered significantly after surgery, the difference was statistically significant. But the intervertebral space height were partly lost at the last follow-up, and there was significant difference compared with postoperative. During the follow-up, no pedicle screw loosening, displacement, rupture, or anterior and lateral displacement of cage occurred. The fusion rate was 97.1% in the posterior fusion group and 100% in the oblique lateral fusion group. There was no statistical difference between the two groups.In terms of ODI index: the posterior fusion group recovered from 48.6±6.1 preoperative to 10.2±2.2 at the last follow-up, and the oblique lateral fusion group recovered from 49.0±5.7 preoperative to 9.3±1.8 at the last follow-up. There was statistically difference between last follow-up and preoperative in the two groups. The incidence of complications in the posterior fusion group was 22.86%, and the incidence in the oblique lateral fusion group was 23.68%. There was no significant difference between the two groups. Conclusion:Both the two decompression and fusion methods have achieved good clinical results in the treatment of lumbar spinal stenosis, with the advantages of less trauma, good stability, fast recovery, and high fusion rate. Compared with posterior decompression and fusion methods, the advantages of OLIF are more obvious, such as less bleeding,lower risk of nerve injury and good indirect decompression of spinal canal. Therefore, the OLIF technique can be a better choice for surgical treatment of lumbar spinal stenosis.

Objective To set up and apply a standardized communication system of adolescents and young adults (AYAs) cancer patients,in order to improve AYAs cancer patients' psychological distress and other negative emotions,as well as promote social support and quality of life of patients.Methods A AYAs cancer patients standardized communication system,suitable for China's national conditions,was preliminarily built.Using randomized controlled trials,a total of 171 subjects,selected from 486 cases of AYAs cancer patients,in the Third Xiangya Hospital of Central South University and Hunan Cancer Hospital from August to September in 2016,were intervened with a set of standardized communication system.The Mental Distress Thermometer (DT),Hospital Anxiety and Depression Scale (HADS),Social Support Rating Scale (SSRS) and Concise Health Status Questionnaire (SF-36) were used as evaluation indexes to observe the psychological distress,emotion,social support and quality of life of the three groups of subjects before intervention,immediately after intervention,1 month after intervention and 3 months after intervention.Results At the follow-up of 3 months after intervention,38 cases were lost,14 cases in communication group (final n =43),11 cases in music therapy group (final n =46),and 13 cases in routine group (final n =44)..There was no significant difference in the evaluation indexes between the communication group,music treatment group and the routine group before intervention (P ＞ 0.05).There were statistically significant differences in scores of psychological pain,anxiety and depression,and social support in the 3 groups,before and immediately after intervention,1 month and 3 months after intervention (P ＜ 0.05).The scores of psychological pain,anxiety and depression,social support and quality of life in the communication group 1 month after intervention were statistically significant compared with those in the music group and the routine group (P ＜ 0.05).Conclusions Compared to music therapy and regular care,the standardized communication system has significant effect on improving the psychological distress of AYAs with cancer,and can also improve their social support level and quality of life.The clinical validation of the standardized communication system can provide reference for psychological rehabilitation of cancer survivors.

Objective To evaluate the effectiveness and radiographic outcomes of percutaneous kyphoplasty (PKP)/percutaneous vertebroplasty (PKP) in the treatment of stage Ⅲ Kümmell's disease without nerve injury.Methods From September 2012 to September 2016,there were 28 patients with stage Ⅲ Kümmell's disease recruited to study,of which 16 patients were treated with PKP and the other 12 cases with PVP.with a mean age of 78,ranging from 67 to 95,consisted of 3 males and 29 females.All patients had single vertebral body lesions without symptom of spinal cord injury.Visual analogue scores (VAS) and oswestry dysfunction index (ODI) were recorded before surgery,on the 7 d after surgery and at the last follow-up.Meanwhile,Cobb angles,anterior and posterior heights of the injured vertebral body were measured by X-ray lateral radiography at these three time points.Furthermore,the condition of bone cement in the injured vertebral body was observed with the postoperative CT examination.Results All patients completed the operation safely.Twenty-eight patients were followed up for an average of 18 months (ranging from 12 to 36 months),and 4 patients who failed to be followed up were not included in the statistic analysis.There was no vessel or nerve injury in the operation.Thirteen out of 28 individuals who suffered from bone cement leakage showed no clinical symptom,and recovered walking ability between 12 and 24h after operation.Other types of vertebral body fractures due to compression occurred in 3 cases between 6 and 12 months after surgery,and the symptoms were relieved after another PKP.The rates of improvement at the last follow-up in VAS and ODI were 71.4％ (20/28) and 67.9％ (19/28),respectively.There was statistical difference in VAS between before surgery and 7d after surgery (t=16.68,P＜0.01).However,no statistical difference was found in the comparison of VAS between the last follow-up and 7d after surgery (t=0.598,P ＞ 0.05).The difference of ODI between before surgery and 7d after surgery (t=36.830,P＜0.01) and that of ODI between the last follow-up and 7d after surgery (t=7.375,P＜0.01) showed statistical significance.There were statistical differences in both Cobb angle and anterior heights of the diseased vertebral body between before surgery and 7d after surgery (t=2.52,2.29,both P＜0.05).Besides,significant differences were also observed in them between the last follow-up and 7d after surgery (t=2.58,2.24,both P＜0.05).However,there was no statistical difference of the posterior height of the diseased vertebral body before surgery,7d after surgery and at the last follow-up (t=0.935,0.795,P＞0.05).Conclusions PKP/PVP may relieve the clinical symptoms safely and effectively of stage Ⅲ Kümmell's disease without nerve injury,and may correct heights of kyphosis and vertebral.Nevertheless,it may lead to loss of correction and high rate of bone cement leakage.Further observation is needed for the long-term effectiveness.

Objective To investigate the feasibility and effectiveness of bilateral pedicle screw fixation combined with in-terbody fusion for the treatment of lumbar spondylolisthesis (degree Ⅱ or Ⅲ) through muscle-splitting approach. Methods There were 52 patients (16 males and 36 females) analyzed in our study from January 2012 to December 2015. The average age was 54.9 ± 7.21 years (from 35 to 70 years). The history of disease was from 10 months to 15 years, with an average of 66.6 ± 32.71 months. Diagnosis included:degenerative spondylolisthesis in 2 cases, and isthmic spondylolysis in 50 cases. The sites included L4,5 in 18 cases and L5S1 in 34 cases. The degree was Ⅱ in 35 cases and Ⅲ in 17 cases. 27 cases were treated by bilateral pedicle screw fixation combined with interbody fusion through median incision approach (open group) and 25 cases through muscle-split-ting approach (minimally invasive group). The clinical and imaging results were observed and compared between the two groups, including operation time, intraoperative blood loss, postoperative incision drainage, VAS score of lumbar incision pain at 72h post-operative, intraoperative and postoperative complications, interbody fusion rate, multifidus muscle areas and grades at 1 year post-operative, and the improvement of ODI index. Results All the cases were operated successfully. The operation time of open group was shorter than minimally invasive group. However, the intraoperative blood loss and postoperative incision drainage of minimally invasive group was statistically less than open group. The VAS scores of postoperative 72 h were 3.25 (2 to 6) in open group and 1.62 (1 to 3) in minimally invasive group. And the difference was statistically significant. The misplacement rate of pedi-cle screws of minimally invasive group was lower than open group. The average follow-up time was 25.5 months (ranged from 12 to 36 months). The multifidus muscle areas and grades of minimally invasive group were superior to open group at 1 year postopera-tively. Compared to preoperative, the slipping angle, slipping rate, sacral inclination angle and vertebral space height were signifi-cant improved after operation in two groups. The ODI index was improved postoperatively in both two groups, and the difference was statistically significant at the final follow-up. The interbody fusion rate was 92.6％in open group and 96％in minimally inva-sive group, and there was no significant difference between the two groups. No cerebrospinal fluid leak, never injury, pedicle frac-ture or wound infection was found after the operation in two groups. There was no pedicle screw loosening, cage shifting, or degen-eration of the adjacent segment observed during follow-up. Conclusion Bilateral pedicle screw fixation combined with inter-body fusion through muscle-splitting approach has advantages of small incision, less trauma, less bleeding, quick recovery and well clinical results, which can be a better choice in treating lumbar spondylolisthesis (degree Ⅱ or Ⅲ).

OBJECTIVE To analyze the clinical manifestation,diagnosis and treatment of cervical lymph node tuberculosis.METHODS The clinical data of 100 patients with cervical lymph node tuberculosis admitted in our hospital from 2007 to 2015 were retrospectively analyzed.RESULTS Most of the patients with cervical lymph node tuberculosis presented with cervical mass alone,only 8 cases associated with fever,night sweats,fatigue and other systemic symptoms of poisoning.Ninety five patients were diagnosed by postoperative pathological examination,while 15 patients were diagnosed with fine needle aspiration preoperatively.Ninety five patients received surgical treatment with postoperative systemic anti-tuberculosis treatment for 6 months,the remaining 5 patients given standard antituberculosis treatment.All of the patients got satisfactory results.There were three operative methods:simple cervical lymph node resection(31 cases),cervical lymph node dissection(53 cases),and abscess incision debridement(ll cases).All patients had no recurrence.CONCLUSION The clinical manifestation of cervical lymph node tuberculosis are complicated,the positive rate of fine needle aspiration biopsy is low.Postoperative pathological examination can help to further confirm the diagnosis.Surgical treatment combined with postoperative systemic standard anti-tuberculosis therapy can be used to cervical lymph node tuberculosis.

Objective To compare the efficacy of sound therapy and conventional medical treatment in the treatment of chronic tinnitus.Methods CNKI,Wanfang database,Weipu database (VIP),Chinese biomedical literature database (CBM),Pubmed,Embase,OVID,SciVerse ScienceDirect and Cochrane library were used.The data were retrieved up to May 2017,and the relevant literature was screened according to the inclusion and emission standards.The quality of the literatures were analyzed and the data was extracted.Meta analysis was carried out by using Revman 5.2 software with total effective rate,tinnitus handicap inventory(THI) value and visual analogue scale(VAS) value.Results A total of 16 articles (1 594 patients) were included in the literature,including 14 articles in Chinese and 2 articles in English.The total effective rate in the sound therapy group were 86.42 ％ (by patients) and 80.50％ (by ears),while in conventional medical treatment group were 60.62％ (by patients),and 48.10％ (by ear),respectively[P＜0.01 (by patients),P＜0.01 (by ear)].The changes of THI value were analyzed before and after treatment,the difference was statistically significant(P＜0.01).The changes of VAS value were analyzed before and after treatment,the difference was statistically significant (P＜0.05).Conclusion Compared with conventional medical treatment,sound therapy can significantly improve the clinical efficacy of tinnitus treatment and reduce the symptoms in tinnitus patients.

Objective To compare the advantages and disadvantages of three different fixation methods via muscle-splitting approach for the treatment of single segmental lumbar vertebral diseases.Methods All of 90 patients with the single segmental lumbar vertebral diseases were treated from June 2012 to June 2013,including 34 males and 56 females,at the age of 27-76 years old,averagely (53.37± 15.41) years.Twenty-seven patients were treated with unilateral pedicle screws via unilateral muscle-splitting approach (unilateral fixation group).Thirty-three patients were treated with unilateral pedicle screws and contralateral translaminar facet screw via unilateral muscle-splitting approach (combined fixation group).Thirty patients were treated with unilateral pedicle screws via bilateral muscle-splitting approach (bilateral fixation group).Observe and compare the imaging and clinical results of these three groups.Results There were no significant difference in incision length and postoperative wound drainage between these three groups.The operation time was shortest in unilateral fixation group,while longest in bilateral fixation group.In the intraoperative blood loss,the unilateral fixation group was the same as the combined fixation group,while less than the bilateral fixation group.No infection was found after operations.Seven patients experienced epidermal necrosis of the incision,including 1 patient of unilateral fixation group,4 patients of combined fixation group and 2 patients of bilateral fixation group.Three patients suffered from nerve injury,including 2 patients of combined fixation group and 1 patients of bilateral fixation group.The follow-up time was from 12 to 36 months,averagely 25.5 months.The intervertebral height of lesion segments was apparently recovered after surgery,and maintained during the follow-up in these three groups.No significant changes of area and grade of multifidus muscle were detected at 1 year after surgery compared with preoperative.Seven patients experienced endplate cutting and cage partially embedded into vertebral body,including 3 patients of unilateral fixation group,3 patients of combined fixation group and 1 patient of bilateral fixation group.There was no loosening,displacement,breakage or cage shifting.Except 5 patients (2 patients of unilateral fixation group,2 patients of combined fixation group and 1 patient of bilateral fixation group),the remaining cases had well interbody fusion.At the final follow-up time,the JOA score significantly increased compared with preoperative.Besides,unilateral fixation group and combined fixation group were superior to bilateral fixation group.Conclusion Three different fixation methods via muscle-splitting approach for the treatment of single segmental lumbar vertebral diseases had well clinical results.The unilateral fixation and combined fixation via muscle-splitting approach had more advantages.The combined fixation via muscle-splitting approach is an innovation in approach,exposure and fixation aspects.
