BACKGROUND:Currently,spinal endoscopic technology has become the mainstream technology in minimally invasive spinal surgery.The specifications of the instruments for different operating systems are different,and the choice of specific surgical protocols needs to be combined with the actual situation of the patient and the choice of the clinical surgeon. OBJECTIVE:To compare the early efficacy of percutaneous endoscopic interlaminar discectomy for L5-S1 disc herniation under the iLESSYS Delta System and Endo-Surgi Plus System. METHODS:Totally 80 patients with L5-S1 disc herniation were treated with percutaneous endoscopic interlaminar discectomy.Patients were divided into two groups based on the endoscopic system used.Among them,37 cases received the iLESSYS Delta System(Delta group)and 43 cases received the Endo-Surgi Plus System(Plus group).Patient demographic characteristics,perioperative indicators,and complications were analyzed between the two groups.Clinical outcomes were quantified using back and leg visual analog scale scores,Oswestry Disability Index,and Japanese Orthopaedic Association scores at 1 day,1,3,and 6 months after surgery.Patient satisfaction was assessed according to modified MacNab criteria at final follow-up. RESULTS AND CONCLUSION:(1)The operative time and number of arthroplasties in the Plus group were less than those in the Delta group,and the differences were statistically significant(P<0.05).(2)Compared with the preoperative period,the visual analog scale scores,Oswestry Disability Index,and Japanese Orthopaedic Association scores of patients in both groups improved at all follow-up time points,and the difference was statistically significant(P<0.001).(3)There was no statistically significant difference in the comparison of pain visual analog scale scores,Oswestry Disability Index,and Japanese Orthopaedic Association scores of patients in the two groups(P>0.05).(4)At 6-month follow-up after surgery,the MacNab standard excellent and good rates in the Delta group and Plus group were 81%and 79%,respectively,with no significant difference(P=0.823).(5)The incidence of complications was 3%in the Delta group and 2%in the Plus group,but there was no significant difference between the two groups(P=0.914).(6)It is concluded that both iLESSYS Delta and Endo-Surgi Plus surgical systems achieved satisfactory early clinical results in the treatment of lumbar disc herniation,with Endo-Surgi Plus surgical moulding being more efficient and safer.

BACKGROUND:Developmental dysplasia of the hip often leads to limb deformities in children,and the research related to its diagnosis and treatment has been gradually clarified.Recently,the finite element method has been paid attention to by scholars in the research related to developmental dysplasia of the hip because of its advantages. OBJECTIVE:Through literature search and review of the relevant research progress of finite element method in children's developmental dysplasia of the hip and treatment,analyze and summarize its advantages and disadvantages,and explore the direction of further research in the future. METHODS:PubMed,SCI,CBM,and CNKI were searched for relevant articles published from January 2014 to November 2023 with the key words of"developmental dysplasia(dislocation)of the hip,dysplasia of the hip,finite element analysis(method),pavlik harness,fixation in herringbone position,biomechanics,pelvic osteotomies,pemberton,salter,dega,periacetabular osteotomy,children"in Chinese and English.A small number of long-term articles were included,and 62 articles were finally included for analysis through screening. RESULTS AND CONCLUSION:(1)The mechanical environment of hip joint in children with developmental dysplasia of the hip was abnormal.The pressure in acetabulum was uneven.The stress increased and concentrated;the joint contact area decreased,and the local stress concentrated in femoral neck.(2)In the Pavlik sling and herringbone fixation,the mechanical environment of the hip was improved;the concentrated high stress area disappeared and the joint contact area increased,but the excessive abduction angle led to the increase of stress in the acetabulum and the lateral femoral head.(3)After pelvic osteotomy,the stress environment of hip joint and sacroiliac joint was improved.There was no single hinge in the three kinds of osteotomy,and the stress load position was different according to the age of the children.(4)After peri-acetabular osteotomy,the joint contact pressure was close to normal,but it was difficult to recover in patients with non-spherical femoral head.(5)The postoperative X-ray film findings could not show that the joint contact mechanics was the best.(6)It is indicated that the information that cannot be measured in the body can be obtained by using the finite element method,which can be operated in a virtual environment without the limitation of time and ethics.It can directly see the stress change area of normal and developmental dysplasia of the hip,explain the effectiveness of treatment from the point of view of mechanics,establish a specific finite element model and tailor-made operation plan for patients who need osteotomy.There is no standard or unified standard for the finite element modeling of developmental dysplasia of the hip and the material characteristic parameters of children's hip joint.Due to the inherent limitations of finite element method,it is impossible to analyze the model that contains bone,cartilage,ligament,muscle and other elements at the same time.The operation of finite element analysis is difficult,although it has advantages,it is not universal,and the current research sample size is small,which needs to be further expanded and verified.

Chinese Journal of School Health 2025;46(1):53-57
Objective:
To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents.
Methods:
Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents.
Results:
The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01).
Conclusions
Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

[Objective] To investigate and summarize the clinicopathological features, diagnosis, treatment and prognosis of adrenocortical carcinoma with rhabdoid features. [Methods] The clinical diagnosis and treatment of a case of adrenocortical carcinoma with rhabdoid features admitled to Department of Urology, Weifang People's Hospital were reported.The clinical manifestations, pathological features, diagnosis and prognosis of the disease were analyzed in combination with relevant literature. [Results] A 34-year-old male patient was admitted due to scrotal distension and pain that had persisted for 6 months.Imaging examination showed a huge soft tissue tumor in the left adrenal region of the retroperitoneum with compression displacement of the left kidney, leading to obstruction of venous return in the left spermatic vein, which in turn caused varicose veins.The levels of serum renin, angiotensin, aldosterone, cortisol, and catecholamine were within normal ranges.Surgical resection of the tumor was performed, and postoperative pathological examination revealed that the tumor tissue was predominantly composed of rhabdoid cells, exhibiting positive immunohistochemical staining for INI 1, Syn, Calretinin and Vimentin.Genetic testing did not identify any deletion of SMARCB1 and SMARCA4 mutations.Therefore, the diagnosis was adrenocortical carcinoma with rhabdoid features.At the current 20-month follow-up, no recurrence or metastasis was observed.A review of the literature found that only 7 cases of this disease had been reported. [Conclusion] Adrenocortical carcinoma with rhabdoid features is a rare disease, and a definitive diagnosis is dependent upon pathological examination.Surgical resection remains the primary treatment.Long-term follow-up is essential, and further research is needed to evaluate the impact of adjuvant therapy.

Abstract
On September 26, 2024, a municipal hospital in Jiaxing City reported a maternal case of Listeria monocytogenes infection. In order to clarify the source of infection, the Jiaxing Center for Disease Control and Prevention immediately conducted the epidemiological investigation, laboratory testing and related disposal work. The case presented with fever (37.9 ℃), gradually intensifying paroxysmal abdominal pain without obvious cause, and went to hospital on the day of onset. Due to fetal intrauterine distress, a male infant was delivered by cesarean section on the same day. The epidemiological investigation identified that the case usually consumed fruits, often store fruits such as watermelon and grapes in the refrigerator alongside raw meat, and the refrigerator had never been cleaned or disinfected, posing a risk of cross contamination. Laboratory tests on amniotic fluid sample from the pregnant woman, infant blood sample showed positive results for Listeria monocytogenes infection. One strain of Listeria monocytogenes was detected in a smear sample from the inner wall of the refrigerator, and all the strains were ST2 type. Consuming fruits contaminated with Listeria monocytogenes may be the main source of infection. Food safety education for pregnant women and their family members should be strengthened to reduce the risk of infection.

ObjectiveTo investigate the key targets of Jianpi Yiqi prescription (JYP) in the treatment of hepatocellular carcinoma (HCC) based on network pharmacology and explore the effect of JYP on the invasion and proliferation of hepatocellular carcinoma cells via protein tyrosine phosphatase, non-receptor type 1 (PTPN1) by bioinformatics analysis and CRISPR/Cas9. MethodsThe potential targets of JYP in the treatment of HCC were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), SwissTargetPrediction, GeneCards, NCBI, and CTD. Additionally, the active components of JYP that could interact with PTPN1 were screened out, and then molecular docking between the targets and active components was performed in Autodock 4.0. UALCAN, HPA, and LinkedOmics were used to analyze the expression of PTPN1 in the HCC tissue, and the relationship of PTPN1 expression with the overall survival (OS) of HCC patients was discussed. CRISPR/Cas9 was used to knock down the expression of PTPN1 in HepG2 and SK-hep-1 cells, and the knockdown effect was examined by sequencing, Real-time PCR, and Western blot. HepG2 cells were classified into blank control, low-, medium-, and high-dose JYP (5.25, 10.5, 21 g·kg-1), and PTPN1 knockout groups. Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of PTPN1 in HepG2 cells of each group. The effects of JYP and PTPN1 knockdown on the proliferation, invasion, and apoptosis of HepG2 cells were detected by Cell Counting Kit-8 (CCK-8), Transwell, and Annexin V-FITC/PI methods, respectively. ResultsJYP had the most active components targeting PTPN1, and 31 of the active components had the binding energy less than -5.0 kcal·mol-1 in molecular docking. The mRNA and protein levels of PTPN1 in the HCC tissue were higher than those in the normal tissue (P<0.01). Compared with that in the normal tissue, the mRNA level of PTPN1 in the HCC tissue was up-regulated at the pathological stages Ⅰ-Ⅲ and grades G1-G3 (P<0.01), and it was not significantly up-regulated at the stage Ⅳ or grade G4. The mRNA level of PTPN1 in the TP53-mutated HCC tissue was higher than that in the TP53-unmutated HCC tissue (P<0.01). The high mRNA level of PTPN1 was associated with the OS reduction (P<0.01). After treatment with the JYP-containing serum or knockdown of PTPN1, HepG2 cells demonstrated decreased proliferation and invasion and increased apoptosis (P<0.01). ConclusionPTPN1 may be one of the core targets of JYP in the treatment of HCC. It is highly expressed in the HCC tissue and cells, which is associated with the poor prognosis of patients. The expression level of PTPN1 is significantly up-regulated in the HCC tissue of the patients with TP53 mutation. However, TP53 mutation or deletion does not affect the expression of PTPN1 in HCC cells. JYP can significantly down-regulate the expression of PTPN1 to inhibit the proliferation and invasion and promote the apoptosis of HCC cells.

Minimally conscious state (MCS) is at the edge between closed and open consciousness, but it still belongs to the category of "wind-strike block" syndrome. The basic pathogenesis of MCS is the obstruction of pathogenic qi, orifices closed and spirit hidden, with pathological factors including phlegm, fire, and blood stasis. Wind movement and water retention may also be present, and often leading to deficiency syndrome due to the exhaustion of qi, blood, yin, and yang at later stages. Treatment chooses Shexiang (Moschus) as the chief medicinal, emphasizing combination of medicinals and urgency of medication administration; the key therapeutic method is to open the orifices, with focuses on expelling pathogens and reinforcing healthy qi. For patients with severe phlegm or fire, use Xiaochengqi Decoction (小承气汤) to open the lower orifices, discharge heat and unblock the bowels, combined with Shexiang (Moschus) and Niuhuang (Bovis Calculus) to open the upper orifices, awaken the spirit and guide qi. For patients with turbid phlegm as the predominant, temporarily replace Shexiang (Moschus) with Baizhi (Angelicae dahuricae radix), using Ditan Decoction (涤痰汤) to eliminate phlegm to open the orifices, when turbid phlegm gradually subsided, Shexiang (Moschus) could be added. For patients with blood stasis as the predominant, Tongqiao Huoxue Decoction (通窍活血汤) will be used to activate blood and open orifice, if the blood circulates, the endogenous wind will be calmed, the water will be induced, the orifices will open and the consciousness will restore. For patients with closed orifices and body deficiency, the treatment should open the orifices and reinforce healthy qi, and consider the root and branch simultaneously; qi deficiency syndrome can be addressed with Buyang Huanwu Decoction (补阳还五汤) to boost qi and reinforce healthy qi; yin deficiency syndrome can be treated with Shaoyao Gancao Decoction (芍药甘草汤) combined with Fengsui Pill (封髓丹) to nourish yin, soften sinews, and secure kidney essence; yang deficiency can be managed by using Dihuang Yinzi Decoction (地黄饮子) to enrich yin, supplement yang, and open the orifices.

BACKGROUND:How to repair bone defect has been a clinical problem for a long time.The effective ingredients of traditional Chinese medicine have good biological activity and therapeutic effect,and the combination of effective ingredients of traditional Chinese medicine and tissue engineering materials has a broad prospect in the field of bone repair.The combination of different effective ingredients of traditional Chinese medicine and scaffolds has similarities in their functional relationships. OBJECTIVE:To collect the cases of the combinations of effective ingredients of traditional Chinese medicine and scaffolds,then analogize tissue engineering scaffolds and effective ingredients of traditional Chinese medicine into two types of traditional Chinese medicine that generate compatibility relationships based on the inspiration of the compatibility of seven emotions and summarize the relationship between the two based on their functional relationships. METHODS:Relevant articles from January 1998 to January 2024 were searched in PubMed and China National Knowledge Infrastructure(CNKI),using English search terms"traditional Chinese medicine,Chinese medicine,traditional Chinese medicine monomers,bone defect,bone repair,bone tissue engineering,tissue engineering,scaffold"and Chinese search terms"traditional Chinese medicine,effective ingredients of traditional Chinese medicine,traditional Chinese medicine monomers,bone tissue engineering,bone tissue engineering scaffold,scaffold,tissue engineering,bone defect,bone repair."A total of 88 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Both tissue engineering scaffold materials and active ingredients of traditional Chinese medicine have been widely used in the field of bone repair.Although they have obvious advantages in osteogenesis,there are still many shortcomings.Many studies are dedicated to preparing composite materials from the two,hoping to exert a detoxification and synergism through the interaction between the two.(2)Some drugs and materials can promote each other in osteogenesis,antibacterial,and promoting angiogenesis,enhancing their original effects.Inspired by the traditional concept of prescription compatibility,this article summarized it as a"Mutual promotion"relationship and provided examples to support it.(3)Some drugs can enhance the strength of materials,while some materials can achieve sustained release and controlled release effects,increase drug loading and stability,or achieve targeted delivery of drugs loaded on them.The article summarized this unilateral enhancement effect as a"Mutual assistance"relationship.(4)The combination of some traditional Chinese medicine and materials can reduce the toxic side effects of the other party.The article summarizes this detoxification relationship as"Mutual restraint and detoxification."(5)The article provided a new perspective on traditional Chinese medicine composite scaffolds,inspired by the seven emotions compatibility relationship and based on the classification of action relationships.It introduced traditional Chinese medicine concepts into the field of tissue engineering,providing new research ideas for subsequent researchers of composite scaffolds,and providing certain convenience in material selection and matching.

BACKGROUND:Repetitive trans-spinal magnetic stimulation(rTSMS)can inhibit inflammatory responses following spinal cord injury.rTSMS applies magnetic field stimulation to the spinal cord region to modulate neuronal excitability and synaptic transmission,thereby promoting plasticity and repair of the nervous system. OBJECTIVE:To observe the effects of rTSMS on the Toll-like receptor 4(TLR4)/nuclear factor(NF)-κB/NLRP3 signaling pathway after spinal cord injury and explore its mechanism in promoting motor function recovery. METHODS:Male C57BL/6J mice,SPF grade,were randomly divided into sham surgery group,spinal cord injury group,and rTSMS group.The latter two groups of mice were anesthetized and the T9 vertebral plate was removed using rongeur forceps to expose the spinal cord,and the spinal cord was clamped using a small aneurysm clip for 20 seconds to establish the spinal cord injury model.Mice in the rTSMS group underwent a 21-day rTSMS intervention starting on day 1 after spinal cord injury.The stimulation lasted 10 minutes per day,5 days per week with an interval of 2 days.Basso Mouse Scale scores were used to assess motor function recovery in mice after spinal cord injury at 1,3,7,14,and 21 days after spinal cord injury.Western blot was employed to detect the expression of AQP4,apoptotic factors Bax,Bcl-2,CL-Caspase-3,inflammatory factors tumor necrosis factor-α,interferon-γ,interleukin-6,interleukin-4,and the TLR4/NF-κB/NLRP3 signaling pathway related proteins in the injured spinal cord.Oxidative stress assay kit was used to measure the activity of superoxide dismutase,glutathione peroxidase,and malondialdehyde content at the site of spinal cord injury.Immunofluorescence staining was performed to detect the expression of neuronal nuclei(NeuN). RESULTS AND CONCLUSION:The Basso Mouse Scale score in the rTSMS group was significantly higher than that in the spinal cord injury group(P<0.05).Compared with the spinal cord injury group,the rTSMS group showed a reduction in spinal cord water content.The expression of AQP4 protein,malondialdehyde content,and expression of Bax,Bcl-2,CL-Caspase-3,tumor necrosis factor-α,interferon-γ,interleukin-6,and TLR4/NF-κB/NLRP3 signaling pathway related proteins were all decreased in the rTSMS group,while the activities of superoxide dismutase and glutathione peroxidase,as well as the expression of Bcl-2,interleukin-4,and NeuN,were all increased(P<0.05).These results suggest that rTSMS downregulates the expression of proteins related to the TLR4/NF-κB/NLRP3 signaling pathway,alleviating symptoms after spinal cord injury such as spinal cord edema,oxidative stress,apoptosis,and inflammation,exerting neuroprotective effects,and thereby promoting the recovery of hindlimb motor function after spinal cord injury.
