AIM:To analyze the clinical phenotypes and genotypes of children with incontinentia pigmenti(IP)and enhance clinicians' understanding of the condition.METHODS: A family with IP diagnosed in February 2020 at the ophthalmology department of People's Hospital of Ningxia Hui Autonomous Region was enrolled. The proband and family members underwent comprehensive systemic and ocular examinations. Peripheral venous blood was collected for DNA extraction, followed by whole-exome sequencing and MLPA assay to identify pathogenic variants. Corresponding treatments were administered based on the severity of fundus lesions, and ocular clinical features and therapeutic outcomes were monitored during follow-up.RESULTS: The child in this study was a female, aged 8 years, with typical skin changes and scarring alopecia and dental abnormalities at the time of initial consultation. The results of genetic testing suggested that the child carried a heterozygous deletion of exons 4-10 of the IKBKG gene chrX:153440010-153446570del. The child had asymmetric lesions in both eyes, with severe lesions in the left eye, atrophy of the eyeballs, and ocular B-ultrasound suggesting structural disturbances in the eye, and neovascularization was seen in the peripheral retina of the right eye, and the patient was given laser photocoagulation treatment for the right eye, and no progression of retinopathy was detected during follow-up.CONCLUSION:Children with IP have different ocular clinical phenotypes, and retinal vasculopathy is the main change. Early screening and timely and standardized treatment are crucial for children diagnosed with IP.

Stroke, a major cerebrovascular disease, has high morbidity and mortality. Effective methods to reduce the risk and improve the prognosis are lacking. Currently, uric acid (UA) is associated with the pathological mechanism, prognosis, and therapy of stroke. UA plays pro/anti-oxidative and pro-inflammatory roles in vivo. The specific role of UA in stroke, which may have both neuroprotective and damaging effects, remains unclear. There is a U-shaped association between serum uric acid (SUA) levels and ischemic stroke (IS). UA therapy provides neuroprotection during reperfusion therapy for acute ischemic stroke (AIS). Urate-lowering therapy (ULT) plays a protective role in IS with hyperuricemia or gout. SUA levels are associated with the cerebrovascular injury mechanism, risk, and outcomes of hemorrhagic stroke. In this review, we summarize the current research on the role of UA in stroke, providing potential targets for its prediction and treatment.

One of the key mechanisms underlying resistance against immunotherapy is the reduction in the abundance and functional capacity of immune cells within the tumor microenvironment (TME). Accordingly, the development of novel antibodies and small-molecule agents that target multiple co-inhibitory molecules—whether employed as monotherapies or in combination—holds promise for reinvigorating exhausted T cells and restoring antitumor immune responses. In addition, exploring agonists targeting co-stimulatory molecules represents a promising strategy to enhance the secondary signals necessary for T cell activation and thereby facilitates tumor eradication. However, careful attention must be given to potential toxicities associated with these agents. Furthermore, this review highlights the emerging therapeutic potential of cancer vaccines, oncolytic viruses, diverse cellular therapies, and other innovative strategies designed to augment the efficacy of immunotherapy in non-small cell lung cancer (NSCLC). Moreover, we discuss therapeutic strategies targeting non-proliferating TME components, including cancer-associated fibroblasts (CAFs) and the extracellular matrix (ECM), and hypoxia-alleviating agents and immune homeostasis-supporting probiotics, all aimed at enhancing anti-tumor immunity. In summary, this article emphasizes the critical importance of integrating therapeutics with complementary mechanisms of action while maintaining the balance between efficacy and tolerability in the advancement of precise and effective immunotherapy in NSCLC to an unprecedented level.

Objective: To understand current situation epidemiology and associated factors of suicidal ideation among high school students in Yixing, so as to provide basis for targeted intervention. Methods: From March to May 2019, a questionnaire survey was conducted on 12 799 students from 3 junior high schools and 4 senior high schools in Yixing City, Jiangsu Province, using a stratified cluster random sampling method. Latent profile analysis was used to classify suicidal ideation among high school students, the chi square test was used to compare the differences in suicidal ideation among different characteristics of students, multiple Logistic regression was used to analyze influencing factors, a risk predictive nomogram model was constructed and then verified. Results: Three latent classes of suicidal ideation among high school students was divided into three categories were observed: none or mild, moderate, and severe. Among them, 3 034 (23.7%) had moderate suicidal ideation and 753 (5.9%) had severe suicidal ideation. The Logistic regression results showed that gender was female, academic performance was lower midrange, smoking, drinking, popularity with classmates(less popular and unpopularity), family member relationships(general/occasional contradictions/contradictions), trust in others(more trusted/less trusted/less trusted at all), past or current relationships, physical bullying, relationship bullying, verbal bullying, and sexual bullying were the influencing factors for severe suicidal ideation among students ( OR =3.27； 2.18 ；1.63；1.72；2.66, 6.05；3.00,3.29, 6.38；1.71, 6.04, 12.48； 2.50； 1.59； 2.16； 1.45； 1.63, P <0.05). The nomogram prediction model had good discrimination. Conclusions Suicide ideation is influenced by multiple factors. Family and peer situations, as well as being bullied, are all related to the degree the severity of suicidal ideation. Efforts can be made to improve students family and interpersonal relationships, control bullying, then reduce their suicidal ideation which might help prevent suicide ideation among students.

Objective:To investigate the efficacy of one-stage anterior debridement and bone graft fusion for the treatment of cervical pyogenic spondylodiscitis.Methods:This is a retrospective case series study. Retrospective analysis of clinical data from 23 patients with cervical pyogenic spondylodiscitis treated with one-stage anterior approach debridement and bone graft fusion was performed in the Department of Spinal Surgery, the First Affiliated Hospital of Xinjiang Medical University from January 2015 to January 2020. There were 14 males and 9 females,aged (51.9±12.8) years (range:26 to 82 years). Preoperatively, 14 patients had neurological deficits, classified according to the American Spinal Injury Association (ASIA) impairment scale as follows: grade A in 1 case, grade B in 1 case, grade C in 5 cases, and grade D in 7 cases . All patients underwent the one-stage anterior debridement and fusion procedure. The surgical time, blood loss, hospital stay, fusion time, and surgical complications were documented. Clinical efficacy was assessed using the visual analogue scale (VAS), the neck disability index (NDI), and the ASIA impairment scale. Preoperative and postoperative data were compared using paired sample t tests, repeated measures analysis of variance, and generalized estimating equations. Results:All the 23 patients underwent the operative procedures successfully. The operation time was (102.8±19.8) minutes (range:60 to 140 minutes), blood loss was (84.4±40.2) ml (range:30 to 160 ml), and the length of hospital stay was (17.4±6.0) days (range:10 to 30 days). Blood cultures were positive for the causative pathogen in 14 cases (60.8% positivity rate), while 9 cases had negative results. Irrigation fluid cultures yielded the causative pathogen in 19 cases (82.6% positivity rate), with 4 cases negative. All patients were followed up for more than 12 months, with a follow-up duration of (19.0±5.9) months (range:12 to 36 months). At the final follow-up, VAS improved from (5.9±1.1) points preoperatively to (0.8±0.3) points; NDI improved from (38.3±6.0)% preoperatively to (9.3±3.0)%, with statistically significant differences (both P<0.01). All patients experienced improvement in neurological function, with the exception of one patient in grade C and two in grade D, all other patients recovered to grade E. The C 2-7 Cobb angle and the affected segment Cobb angle were corrected. white blood cell, erythrocyte sedimentation rate and C-reactive protein levels returned to normal. All patients achieved bony fusion, with a fusion time of (8.9±1.9) months (range:6 to 12 months). Two diabetic patients developed postoperative incision infection; no other surgery-related complications occurred in the remaining patients. Conclusion:One-stage anterior debridement and bone graft fusion can correct kyphosis, restore normal alignment, and improve neurological function in the treatment of single and double segment cervical pyogenic spondylodiscitis, representing a viable treatment option for cervical pyogenic spondylodiscitis.

The traditional treatment of intervertebral disc degeneration (IVDD) mainly focuses on symptomatic treatment, and cannot restore the physiological structure and function of the intervertebral disc. Therefore, more and more scholars begin to pay attention to the application of regenerative medicine and its derived therapeutic methods in IVDD. From the histological perspective, the early stage of IVDD shows the imbalance between synthesis and catabolism, but the cell number and tissue structure are relatively complete, and the intervention of exogenous molecules or gene therapy can achieve extracellular matrix (ECM) regeneration. With the progress of IVDD, the replenishment of healthy cells is the key to treatment. In the final stage, the cell number and tissue structure are disordered. Biological materials with certain mechanical strength and cell load can be used to supplement ECM and healthy cells to realize the repair and regeneration of IVDD. Molecular, cell and gene therapy, combined with the application of new biomaterials, the treatment of IVDD is more inclined to compensate for the shortcomings through a combination approach in the future, in order to achieve the purpose of repair and regeneration.

Neurodegenerative diseases are a type of disease characterized by specific types of neuronal loss and progressive progression,mainly represented by Alzheimer's disease and Parkinson's disease.This type of disease,due to its intractable and irreversible symptoms,brings great physical and psychological burden to patients,which is seriously disturbing their normal life.In terms of treatment,there is currently no specific treatment for Alzheimer's disease in clinical practice,and first-line treatment drugs for Parkinson's disease also have great limitations.In traditional Chinese medicine,kidney governs bone,generates marrow,and connects to the brain.In clinical evidence typing,premature aging,fatigue and forgetfulness,and tremor of limbs caused by kidney deficiency and medullary reduction are considered to be the main pathologies of these diseases.Di-Huang-Yin-Zi decoction which is derived from the"General Records of Holy Universal Relief",is recorded as a good formula for nourishing kidney yin and filling kidney yang.Clinical data shows that this formula has significant therapeutic effects in treating neurodegenerative diseases caused by kidney essence deficiency.Modern research results indicate that its mechanism of action involves inhibiting inflammatory reactions,regulating mitochondrial autophagy,reversing The hypothalamic-pituitary-adrenal axis abnormalities,and neuroprotection.The main effective ingredients in this formula include loganin,echinarin,and schisandrin A.This article aims to summarize and analyze the clinical efficacy,mechanism of action,and active ingredients of Di-Huang-Yin-Zi decoction in the treatment of Alzheimer's and Parkinson's disease in recent years,in order to clarify the research status of Di-Huang-Yin-Zi decoction in the neurodegenerative disease and provide reference for further research.

Objective:To evaluate the safety and effectiveness of single posterior osteotomy in the correction of rigid cervical spine deformities (CSD) and to explore the indications and key surgical techniques involved.Methods:A retrospective analysis was conducted on the clinical data of 9 patients with rigid CSD who underwent single posterior osteotomy correction between June 2012 and June 2023 in the Department of Spine Surgery at the First Affiliated Hospital of Xinjiang Medical University. The cohort comprised 4 males and 5 females, with a mean age of 19.8±27.2 years (range, 7-48 years). Among these, 5 cases were congenital CSD, 3 were post-tuberculosis deformities, and 1 was iatrogenic. Various coronal and sagittal alignment parameters were measured, including C 1, 2 angle, cervical lordosis (CL), structural scoliosis angle (SSA), structural kyphosis angle (SKA), head tilt (HT), C 2-C 7 sagittal vertical axis (CSVA), sagittal vertical axis (SVA), coronal balance distance (CBD), T 1 slope (T 1S), and the difference between T 1 tilt and cervical lordosis (T 1S-CL). Clinical outcomes were assessed using the neck disability index (NDI), visual analogue scale (VAS), and Scoliosis Research Society-22 questionnaire (SRS-22). Results:The average operation time was 273.9±76.1 min, with an average blood loss of 472.2±128.8 ml. All 9 patients were followed up for an average of 45.2±41.8 months (range, 12-116 months). A total of 7 patients underwent single-segment osteotomies (C 3, C 6 and C 7: 1 case each; C 5: 4 cases), and 2 patients underwent double-segment osteotomies (C 2 and C 7, C 3 and C 4). Four cases involved pedicle subtraction osteotomy (PSO), while 7 cases required vertebral column resection. The upper instrumented vertebra (UIV) was located at the occiput in 1 case and in the cervical spine in 8 cases. The lower instrumented vertebra (LIV) was located in the upper thoracic spine in 6 cases and in the cervical spine in 3 cases, with 2 of the latter cases having both UIV and LIV in the cervical spine. The average number of fused segments was 7.6±4.4 segments (range, 2-12 segments). All patients achieved successful bone fusion within an average of 8.8±3.2 months (range, 6-12 months). Preoperatively, the mean values for CL, SSA, SKA, HT, and CBD were 19.8° (17.2°, 30.5°), 27.4°(23.3°, 30.4°), 28.4°(25.6°, 30.1°), 9.0°(6.2°, 12.3°), and 18.5(12.3, 23.6) mm, respectively. Postoperative improvements were noted with values of -11.1°(-8.8°, -14.4°), 1.3°(0.8°, 1.6°), -11.1°(-8.6°, -14.5°), 1.6°(0.5°, 2.2°), and 9.4 (4.8-13.5) mm, respectively. At the final follow-up, these parameters were maintained, with values of -11.0°(-8.8°, -14.3°), 1.2°(0.8°, 1.5°), -11.0° (-8.6°, -14.3°), 1.5°(0.5°, 2.2°), and 9.4(4.8, 13.4) mm, respectively. Statistically significant improvements were observed between preoperative and postoperative measurements ( P<0.05), except for C 1, 2 angle, CSVA, SVA, T 1S, and T 1S-CL ( P>0.05). NDI and SRS-22 scores showed significant improvements postoperatively ( P<0.05), while VAS scores did not show a significant change ( P>0.05). Postoperative complications included transient nerve injury in two patients, one case of right central retinal artery occlusion, and one case of vertebral artery injury. Conclusion:This study confirms the safety and efficacy of single posterior osteotomy for treating rigid CSD of various etiologies. Standard PSO or modified techniques are effective for correcting cervical kyphosis, while hemivertebra resection and concave-side distraction are recommended for congenital scoliosis or kyphoscoliosis.
