Objective To investigate the clinical efficacy of the"dynamic and static combination"approach in the treatment of Hepple Ⅰ-Ⅲ type osteochondral lesions of the talus(OLT),utilizing external ankle shaking,pulling,and poking manipulations in conjunction with ankle brace fixation.Methods A total of 82 patients diagnosed with OLT,who sought treatment at four hospitals between June 2022 and December 2023,were included in the study.Both the experimental and control groups received ankle immobilization using braces through-out the treatment period.The control group was administered Voltaren Emulgel topically twice daily(morning and evening),with each treatment course lasting 30 days,for a total of one course.The experimental group received additional therapeutic intervention involving shaking,pulling,and poking manipulations,conducted twice weekly,with the same duration and number of treatment courses as the control group.Follow-up assessments were scheduled at 2 weeks,4 weeks,and 2 months post-treatment.Outcome measures included the pain rating index(PRI),visual analogue scale(VAS)for pain intensity,current pain intensity(PPI),American Orthopaedic Foot & Ankle Society(AOFAS)ankle and hindfoot scores,proprioceptive function,and the size of OLT.Results During the longitudinal assessment conducted at 2-week,4-week,and follow-up intervals,the experimental group exhibited superior clinical outcomes compared to the control group,with statistically significant decreases in PRI,PPI,and AOFAS scores(all P＜0.05).VAS scores showed progressive improvement over time,with significant intergroup differences observed at both the 4-week and follow-up assessments(P＜0.05).Biomechanical analysis performed post-intervention indicated improved kinematic repositioning accuracy in the experimental group,as reflected by significantly reduced active-passive error angles(P＜0.05).Importantly,measurements of OLT area revealed notable therapeutic effects in the experimental group(P＜0.05),whereas no statistically significant changes were observed in the control group throughout the study period(all P＞0.05).Conclusions Under the guidance of the"dynamic and static combination"concept,the integration of shaking,pulling,and poking manipu-lation with conventional Western medicine-based conservative treatment for OLT demonstrates more pronounced advantages in alleviating pain,improving ankle joint function,restoring proprioception,facilitating lesion recovery,and enhancing overall quality of life.

Background and purpose:Accurately locating pulmonary nodules is the key to the success of thoracoscopic surgery.This study aimed to investigate the strategy and evaluate the feasibility,safety,and clinical value of thoracoscopic surgical treatment for pulmonary nodules located beneath the interlobar pleura and close to the pulmonary hilum.Methods:The patients who underwent pulmonary nodule surgery at Liaocheng Tumor Hospital from May 2023 to November 2024 were enrolled,and the patients who did not meet the inclusion criteria were excluded.This study was approved by the Ethics Committee of Liaocheng Tumor Hospital(EC-20240112-1020)and informed consent was obtained from the patients.The research was designed as a prospective single-arm study.The patients were treated with wedge resection,which was performed following CT-guided localization,where the location needle was inserted through the interlobar pleura.The feasibility of the procedure was evaluated by analyzing the success rate of preoperative localization and perioperative complications.Results:A total of 28 patients who met the inclusion criteria were included in this study.There were 5 male and 23 female patients with an average age of(56.0±8.5)years(range 38-69 years).In all,28 patients with 28 nodules underwent thoracoscopic wedge resection,and the preoperative CT-guided localization was successfully performed in all patients,without urgent complications.The mean operation time of thoracoscopic surgery was(15.6±4.0)min,intraoperative bleeding was(20.9±14.3)mL,and postoperative drainage was(214.3±62.2)mL.No cases of postoperative air leaks or conversion to thoracotomy were observed.The average length of hospital stay was(5.4±0.9)days.The postoperative histological diagnosis revealed 3 benign lesions(pulmonary fibrosis in 2 cases,atypical adenomatous hyperplasia in 1 case)and 25 malignant lesions(adenocarcinoma in situ in 5 cases,minimally invasive adenocarcinoma in 16 cases,and invasive adenocarcinoma in 4 cases).Conclusion:Thoracoscopic wedge resection following CT-guided nodule localization through the interlobar pleura is a feasible approach for nodules located beneath the interlobar pleura and close to the pulmonary hilum.The method ensures precise tumor localization,adequate margin,and minimal loss of normal lung tissue,with a low incidence of postoperative complication,which has important guiding significance for the surgical treatment of pulmonary nodules in such special locations.

Objective:To analyze the correlation between serum antibody titers of anti-contactin associated protein-like 2 (CASPR2) antibody and clinical features and prognosis in encephalitis.Methods:A retrospective analysis was conducted on the clinical data of 31 patients diagnosed with anti-CASPR2 antibody encephalitis at the First Affiliated Hospital of Zhengzhou University from January 2018 to April 2024. Patients were divided into low titer group (≤1∶32) and high titer group (>1∶32) based on serum anti-CASPR2 antibody titers, and their clinical characteristics, auxiliary examination results, and prognosis were compared between the two groups.Results:Among the 31 patients with anti CASPR2 antibody encephalitis (male∶female=1∶1.4), there were 16 cases in the low titer group and 15 cases in the high titer group; The age of patients in the high titer group was (33.9±17.9)years, which was lower than that of patients in the low titer group [(52.9±17.9)years], and the difference was statistically significant ( P=0.006). The proportion of patients with prodromal infection in the high titer group (6/15) was higher than that in the low titer group (1/16, P=0.037). There was no statistically significant difference in the cerebrospinal fluid related test results, imaging examination of intracranial abnormal lesions, abnormal electroencephalogram, serum abnormal tumor markers, and serum abnormal rheumatic immune indicators between the two groups of patients (all P>0.05). During hospitalization, one patient in the high titer group died; During the follow-up period, one patient died and three patients relapsed, all of whom were in the high titer group. During follow-up, the mRS scores of 6 patients ranged from 3 to 5 points (indicating functional impairment), with 4 cases in the high titer group and 2 cases in the low titer group. The proportion of patients with poor prognosis in the high titer group (9/15) was higher than that in the low titer group (2/16), and the difference was statistically significant ( P=0.021). Conclusions:Patients with high serum anti-CASPR2 antibody titers and encephalitis have a lower age of onset and are prone to pre infection triggers. High antibody titers may be associated with a higher risk of disease recurrence and poor prognosis for patients.

Objective To explore the correlation between serum forkhead box protein O1(FOXO1)and myeloid cell leukemia protein 1(MCL1)in patients with acute ischemic stroke(AIS)and the severity and short-term prognosis of the disease.Methods A total of 359 AIS patients admitted to the hospital from Feb-ruary 2020 to February 2023 were regarded as the study subjects.According to the National Institutes of Health Stroke Scale(NIHSS)scores at admission,359 patients were grouped into mild group(131 cases),moderate group(156 cases),and severe group(72 cases),and the patients were separated into a good progno-sis group(263 cases)and a poor prognosis group(96 cases)based on the modified Rankin Scale(mRS)score after 90 days of onset.Real-time fluorescence quantitative PCR(qPCR)was applied to detect serum FOXO1 mRNA expression level.Enzyme linked immunosorbent assay(ELISA)was applied to detect the expression level of serum MCL1.Multivariate Logistic regression analysis method was applied to analyze the factors that affected the short-term prognosis of AIS patients.Receiver operating characteristic(ROC)curve was applied to analyze the predictive value of serum FOXO1 mRNA and MCL1 expression for short-term prognosis of AIS patients.Results Compared with the mild group,the serum FOXO1 mRNA level in the moderate and severe groups was obviously reduced(P<0.05),while the MCL1 level was obviously increased(P<0.05).The FOXO1 mRNA level in the severe group was lower than that in the moderate group(P<0.05),and the MCL1 level was higher than that in the moderate group(P<0.05).Compared with the good prognosis group,the serum FOXO1 mRNA level was significantly lower in the poor prognosis group,and the level of MCL1,C-reactive protein(CRP),age,NIHSS score,and proportion of diabetes were significantly higher than those in the poor prognosis group(t/χ2=11.328,7.617,5.344,2.314,16.788,4.459,all P<0.05).The re-sults of multivariate Logistic analysis showed that FOXO1 mRNA was a protective factor for the short-term prognosis of AIS patients(OR=0.726,P<0.05),while MCL1,CRP,and NIHSS score were independent risk factors affecting the short-term prognosis of AIS patients(OR=1.334,1.319,1.442,P<0.05).The results of ROC curve showed that the area under the curve(AUC)of serum FOXO1 mRNA level for predicting poor short-term prognosis of AIS patients was 0.807,with sensitivity and specificity of 69.79%and 85.93%re-spectively.The AUC of serum MCL1 level for predicting poor short-term prognosis of AIS patients was 0.824,with sensitivity and specificity of 71.87%and 84.79%,respectively.The AUC of the combination of serum FOXO1 mRNA and MCL1 for predicting poor short-term prognosis of AIS patients was 0.886,with sensitivity and specificity of 85.42%and 81.37%,respectively.Conclusion The expression of FOXO1 mRNA and MCL1 is abnormal in AIS patients,they are related to the severity of AIS and have high predictive value for the short-term prognosis of AIS.

Objective To investigate the role of bufalin(BU)in inhibiting M2-type macrophage-mediated colorec-tal cancer metastasis.Methods Human acute leukemia mononuclear cells(THP-1)were differentiated into M0 macrophages using phorbol ester induction(PMA)for 48 hours.The M0 macrophages were then treated with IL-4 and IL-13 medium.Surface markers and morphological changes were observed through ELISA,morphology,and RT-qPCR experiments.RT-PCR and ELISA experiments were conducted to detect the surface markers TGF-β and IL-10 of M2 macrophages.The secretion level of IL-6 in the supernatant of M2 macrophages and colorectal cancer cells HCT116 was compared using ELISA.Additionally,the effect of conditioned medium on colorectal cancer cell HCT116 was assessed through Transwell,Wound healing,RT-qPCR,and Western blot experiments.Subsequent-ly,bufalin was added to the conditioned medium and the changes in AKT/PI3K protein,migration,and epithelial-mesenchymal transition ability in HCT116 were observed using Western blot,Transwell,Wound healing and RT-qPCR experiments.Results THP-1 were successfully differentiated into M2 macrophages.The activation of AKT/PI3K protein in HCT116 cells was induced by the secretion of IL-6 from M2 macrophages,which in turn promoted the migration and epithelial-mesenchymal transition ability of the HCT116 cells.The migration and epithelial-mes-enchymal transition mediated by M2 macrophages in HCT116 cells were effectively inhibited by Bufalin.Conclu-sion The release of IL-6 from M2 macrophages activates the AKT/PI3K signaling pathway in colorectal cancer cells,thereby promoting their migration and epithelial-mesenchymal transition capacity.Moreover,bufalin exhibits inhibitory effects on this effect.

Objective:To explore the effect of acute kidney injury(AKI)on near-term survival after lung transplantation(LT)in patients with idiopathic pulmonary fibrosis(IPF).Methods:Through consulting electronic medical records, anesthetic modes and Chinese Lung Transplant Registration System, clinical data are retrospectively reviewed for 275 IPF patients undergoing LT at Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2017 to April 2021.According to the diagnostic criteria of Kidney Disease: Improving Global Outcomes(KDIGO), they are divided into two groups of AKI(169 cases)and non-AKI(106 cases).Perioperative findings of two groups are recorded.Then univariate and multivariate Cox regression models are employed for determining whether or not inter-group differences existed in survival rates post-LT.Also AKI is staged according to the KDIGO.And the effect of stage 1/2/3 AKI on near-term postoperative prognosis is examined.Results:The differences are significantly different in recipient gender, creatinine, 6-minute walking test, forced vital capacity(FVC), lung allocation score, oxygenation index, N-terminal pro-brain natriuretic peptide(NT-Pro BNP), preoperative hormone use and volume of crystal infusion( P<0.05).After multivariate Cox regression correcting for covariates, no statistical significance exists in effect of AKI stage 1 on near-term postoperative survival rate( P<0.05).AKI stage 2/3 still has statistical significance in risk of mortality at Day 30/90/180/365 post-operation( P>0.05). Conclusions:As a common complication post-LT, AKI significantly affects near-term postoperative prognosis of transplant IPF patients.Stage 2/3 AKI impacts near-term postoperative survival while stage 1 AKI is not associated with higher mortality.

Objective:To investigate the clinical manifestation, genetic characteristics, treatment and prognosis of Crouzon-like syndrome.Methods:Clinical data of one case of Crouzon-like syndrome diagnosed in Children′s Hospital Affiliated to Zhengzhou University in May 2019 were collected, including clinical test, treatment plan, follow-up outcomes. The clinical characteristics and the mutation characteristics of IL11RA-related Crouzon-like syndrome were analyzed combined with the literature.Results:The male proband, five years and four months old, was admitted with the main clinical manifestations including headache, vomiting, exophthalmos, ocular hypertelorism, nasal root flat and scaphocephaly. CT showed that the cerebellar tonsil moved down slightly, the occipital magnum was full, the bilateral cranial plates were locally thinner, the bilateral cranial diameters were increased, and the cranial seams were closed. Magnetic resonance imaging showed ChiariⅠmalformation. The mutation c.40_63del and splice site mutation c.811-2A>G of the patient′s IL11RA gene were screened by whole exome sequencing. Sanger sequencing showed that the mutations are compound heterozygous and both are first reported. The mutation c.811-2A>G was derived from the patient′s mother, and the other one is de novo.Conclusions:The main clinical manifestations of Crouzon-like syndrome are craniosynostosis and midface hypoplasia and ocular deformity. The study identified two novel mutations in the Crouzon-like syndrome related IL11RA gene. Genetic sequencing is helpful for accurate diagnosis and timely surgical treatment.
