Objective To investigate the changes and diagnostic value of serum hypoxia inducible factor 1 subunit alpha(HIF-1α)and Toll-like receptor 4(TLR4)levels in patients with chronic obstructive pulmonary disease(COPD)complicated with pulmonary Aspergillosis infection.Methods A total of 240 COPD patients who visited Xi'an Qinhuang Hospital(hereinafter referred to as the hospital)from December 2020 to Decem-ber 2023 were selected as the study subjects in the study,and another 218 volunteers who underwent physical examinations at the hospital were selected as the control group.The COPD patients were separated into an in-fected group(124 cases)and an uninfected group(116 cases)based on whether they had pulmonary Aspergil-losis infection.Enzyme-linked immunosorbent assay was applied to detect the levels of HIF-1α and TLR4 in patients.Fully automated biochemical analyzer was applied to detect lactate dehydrogenase(LDH)and albu-min(ALB)levels.Multivariate Logistic regression was applied to analyze the influencing factors of infection in COPD patients.Pearson correlation was applied to analyze the correlation between HIF-1α and TLR4 levels in the infected group.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic val-ue of HIF-1α and TLR4 levels for the occurrence of infection in COPD patients.Results Compared with the control group,the COPD group showed an increase in HIF-1α and TLR4 levels(P＜0.05).Compared with the uninfected group,the proportion of dyspnea,antibiotics＞3 types,the duration of antibiotic use ≥ 14 days,mechanical ventilation procedures,the longer glucocorticosteroid(GC)use time,and levels of LDH,HIF-1α,TLR4 in the infected group were higher(P＜0.05),while the level of ALB was lower(P＜0.05).The types of antibiotics＞3 types,the duration of antibiotic use ≥ 14 days,the duration of GC use,and elevat-ed levels of LDH,HIF-1α,and TLR4 were independent risk factors for infection in COPD patients(P＜0.05),while elevated level of ALB was an independent protective factor for infection in COPD patients(P＜0.05).The levels of HIF-1α and TLR4 in the infected group were positively correlated(r=0.453,P＜0.001).The area under the curve(AUC)of HIF-1α and TLR4 in diagnosing infection in COPD patients alone was 0.816 and 0.813,and the AUC of their combined diagnosis was 0.930,which was better than their indi-vidual diagnoses(Zcombination-HIF-1α=4.923,Z combination-TLR4=5.192,P＜0.001,P＜0.001).Conclusion The levels of HIF-1α and TLR4 increase in COPD patients,and further increase after infection with pulmonary Aspergil-lus.They are independent risk factors for infection in patients,and the two are positively correlated.The combined di-agnosis of pulmonary aspergillosis has certain value and provides a theoretical basis for clinical diagnosis.

Objectives:To investigate the clinical efficacy of bilateral mini-open Wiltse approach transforami-nal lumbar interbody fusion(MO-TLIF)in the treatment of degenerative lumbar diseases in the elderly.Meth-ods:A retrospective analysis was conducted on 62 elderly patients with single-segment degenerative lumbar diseases who underwent MO-TLIF or minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)inthe First Affiliated Hospital of Naval Medical University between September 2017 and August 2020.Among them,37 were male and 25 were female,aged 68.0±5.5 years.The patients were divided into the MO-TLIF group(32 cases)and the MIS-TLIF group(30 cases).There were no statistically significant differences between the two groups in terms of gender ratio,age,body mass index(BMI),surgical segment,disease duration,or follow-up time(P＞0.05).The differences between the two groups were compared in terms of operative time,in-traoperative blood loss,intraoperative fluoroscopy,postoperative wound drainage,time to ambulation,hospital stay,complications,and fusion rate.The visual analogue scale(VAS),lumbar Japanese Orthopedic Association(JOA)scores,and Oswestry disability index(ODI)before surgery,at 3 months postoperatively,and at the final follow-up were recorded and compared.Results:The two groups of patients all successfully completed the surgery without significant surgery-related complications.There were no statistically significant differences be-tween the MO-TLIF and MIS-TLIF groups in terms of intraoperative blood loss(80.3±25.1mL vs.72.3±21.8mL),postoperative wound drainage volume(30.7±10.2mL vs.29.3±9.0mL),or hospital stay(5.4±0.9d vs.5.4±0.8d)(P＞0.05).Compared with the MIS-TLIF group,the MO-TLIF group had shorter operative time(90.8±8.8min vs.98.3±8.0min,P=0.001)and fewer number of intraoperative fluoroscopy(4.7±0.7 times vs.7.2±1.4 times,P＜0.001).Both groups showed significant improvement in low back pain VAS score,lumbar JOA score,and ODI at postoperative 3 months and final follow-up compared with preoperative values(P＜0.001),but there were no statistically significant differences between the two groups at the same time points(P＞0.05).At the fi-nal follow-up,no internal fixation-related complications such as screw or rod breakage were observed in both groups,and all the cases achieved bone fusion.Conclusions:Bilateral MO-TLIF can achieve good therapeutic outcomes in treating single-segment degenerative lumbar diseases,which can reduce intraoperative fluoroscopy frequency and shorten operative time comparing with MIS-TLIF.

Cardiovascular disease is an important problem affecting global human health,and its incidence is in-creasing year by year.In recent years,more and more studies have shown that sex-determined region of Y(SRY)-related high mobility group-box 9(SOX9)gene,as a highly conserved transcription factor,is widely involved in regulating cardiac dvelopment and cardiovascular disease progression at the level of gene transcription.SOX9,alone or in combination with other proteins,can bind to corresponding cis-acting elements in the downstream target gene promoter region and participate in regulating the expression of downstream heart development or cardiovascular disease-related genes.Therefore,SOX9 has the potential to be a new therapeutic target for the cardiovascular system.In this paper,the structure and function of SOX9 were systematically described,and the latest research progress of SOX9 in cardiac remodeling and vascular remode-ling was summarized,in order to provide new ideas and methods for the prevention and treatment of cardiovascular system diseases in the future.

Objective:To investigate the detection status of pulmonary tuberculosis (PTB) among patients aged ≥65 years in China and provide evidence for improving PTB prevention and control in this population.Methods:The data were collected from the tuberculosis subsystem of Chinese Disease Control and Prevention Information System, and the case information of elderly PTB patients aged ≥65 years old who were registered in designated tuberculosis medical institutions nationwide from January 1, 2015 to December 31, 2023.Descriptive epidemiological methods were used to analyze trends in detection status, regional differences, and demographic characteristics.Results:From 2015 to 2023, 1 567 047 elderly PTB detection were identified, accounting for 25.1% of all PTB patients (1 567 047/6 243 215). The average registration rate for elderly PTB patients was 96.9 per 100 000, approximately twice that of the general population. The registration rate declined over the years ( Z=-2.61, P=0.009) but increased in 2018 and 2023. The proportion of elderly PTB patients rose annually, from 21.3% in 2015 to 32.4% in 2023 ( Z=2.30, P=0.022). Active case-finding accounted for only 3.0% (47 049/1 567 047) of patients on average during the study period, peaking at 7.3% (14 123/194 615) in 2018 before declining. The registration rates of elderly tuberculosis patients are relatively higher in central and western regions. In the central region, the average registration rate was 113.8 per 100 000, with a proportion of active case detection of 0.4% (2 532/570 059). In the western region, the average registration rate was 130.0 per 100 000, and the proportion of active case-finding was 7.6% (41 973/549 998). Subgroups with notably lower active detection proportions included males (2.5%, 27 443/1 101 091), those aged 80-84 years (2.2%, 2 978/133 855), and migrant populations (0.5%, 1 635/307 673). Conclusions:The burden of PTB among the elderly aged ≥65 years in China remains high, with a low proportion of active case-finding from 2015-2023. There is an urgent need to strengthen health education and active screening to improve the early diagnosis and prevention of tuberculosis in the elderly.

Adolescent idiopathic scoliosis(AIS)is a complex spinal deformity that occurs in adolescents aged 10-18 years.It is more common in female adolescents.Despite extensive research,the precise pathological mechanisms underlying AIS are yet to be fully elucidated.Given its links to abnormal bone growth and reduced bone mineral density,the involvement of mesenchymal stem cells(MSCs)in bone metabolic disorders is considered a plausible contributing factor of AIS.This review summarizes the role of MSCs in the pathogenesis of AIS and provides a forward-looking perspective on the potential clinical application.

Objective To compare the surgical outcomes of the sequence of screw and rod placement for Lenke type 5C adolescent idiopathic scoliosis(AIS).Methods Lenke type 5C AIS patients who underwent posterior orthopedic fusion and fixation in our hospital from Jan.2013 to Dec.2020 were recruited.Based on surgical sequences,22 cases were assigned to bilateral group(after bilateral screw placement,orthopedics was performed on the convex side and then on the concave side),and 20 cases were assigned to convex group(screws placed on the convex side and performed orthopedics,followed by the concave side).The operation-related indicators(including operation time),imaging parameters,quality of life scores were compared between the 2 groups before and 2 years after surgery.Complications of the 2 groups were analyzed.Results The operation time in the bilateral group was significantly longer than that in the convex group([232.8±13.1]min vs[198.4±16.5]min,P＜0.01).At the last follow-up 2 years after operation,the Cobb angle and its correction rate in the convex group were better than those in the bilateral group([8.0±2.3]° vs[9.9±3.2]°,P=0.03;[81.9±5.4]%vs[77.8±5.8]%,P=0.02).The rate of pedicle screw breach rate was 5.4%(17/312)in the bilateral group and 1.4%(4/280)in the convex group,with significant difference(P＜0.01).At the last follow-up 2 years after operation,the treatment satisfaction of quality of life assessment of the bilateral group was 4.61±1.38,and that of the convex group was 4.50±1.44,but there was no significant difference between the 2 groups(P＞0.05).There were no abnormal electrophysiological monitoring or operation-related complications in the 2 groups.Conclusion For Lenke type 5C AIS,the convex side of pedicle screw placement and orthopedics followed by concave side of pedicle screw placement and orthopedics can achieve better surgical effect.

Objective To explore the clinical effect of nursing guided by Neuman's systems model on adolescent idiopathic scoliosis surgery patients.Methods This study is a randomized controlled trial.A total of 120 patients with adolescent idiopathic scoliosis who underwent surgery in our hospital from Jan.to Dec.2023 were enrolled.According to the order of enrollment,they were randomly assigned to experimental group or control group,with 60 patients in each group.The control group received routine nursing,while the experimental group received nursing guided by Neuman's systems model.Independent-sample t test and χ2 test were used to compare the surgical efficacy,postoperative recovery,quality of life,and self-management ability of the 2 groups.Results Six months post-surgery,the main curve Cobb angle in the experimental group was significantly smaller than that in the control group([14.33±0.78]° vs[16.65±1.02]°,P＜0.001).The postoperative bedtime([4.78±1.32])d vs[6.13±1.26]d),incision healing time([13.43±3.29]d vs[15.32±5.23]d),and hospital stay([13.17±5.36]d vs[16.93±3.14]d)were all significantly shorter in the experimental group than those in the control group(all P＜0.05).The overall complication rate in the experimental group was significantly lower than that in the control group(5.00%[3/60]vs 21.67%[13/60],P=0.016).Six months post-surgery,the experimental group scored better in terms of physical functioning,bodily pain,general health,vitality,social functioning,role-emotional,and mental health compared to the control group(all P＜0.05).In terms of patient self-management,the experimental group also had significantly higher scores in common management(17.53±5.98 vs 13.34±7.32)and symptom management(30.95±8.12 vs 27.32±7.87)compared to the control group(both P＜0.05).Conclusion The nursing guided by Neuman's systems model for adolescent idiopathic scoliosis surgery patients can promote their postoperative recovery and improve their quality of life and self-management capabilities.

Objective To summarize the perioperative nursing experience of a child with Angelman syndrome(AS)complicated with moderate scoliosis undergoing posterior 3-dimensional osteotomy correction,fusion,and internal fixation under general anesthesia.Methods The clinical data of the child with AS and moderate scoliosis who underwent surgical treatment in our hospital on Aug.4,2023,were analyzed.A multidisciplinary team was established upon admission.Relevant literatures and evidences were reviewed to develop and implement a"1+X"nursing plan,which included 2 components:"1"(core perioperative nursing priorities for scoliosis)and"X"(multiple AS-related nursing issues and corresponding strategies).Results The surgery was successful,with stable postoperative conditions and significant improvement in spinal curvature.The child's height increased by 7 cm.Discharge occurred on postoperative day 10,with 100%follow-up compliance.The child regained preoperative independent walking ability during follow-up.Conclusion The"1+X"nursing protocol for AS complicated with scoliosis can effectively ensure perioperative safety and promote recovery,which providing insights for perioperative nursing care of other rare diseases complicated with scoliosis.
