Objective To observing the effects of health education on modified lifestyle and behavior patterns among migrant workers. Methods Individuals from two factories were randomly assigned to the intervention group ( n = 262 ; men 129, women 133 ; mean age 31.8) and the control group ( n = 147 ;men 75, women 72; mean age 31.8). The intervention group received 4-months' health education before changes of awareness of health knowledge, cigarette smoking, alcohol consumption, physical activities,mental health and medical consultation. Results In the intervention group, the awareness of the risk of cigarette smoking and alcohol consumption and normal levels of blood pressure and obesity was significantly improved at 4 months(χ2 =59.65, 47.69, 19.50, and 30. 17; all P＜0. 01 ). However, no significant improvement in awareness of AIDS was found in the intervention group. Of the intervention group, some unfavorable lifestyles and behavior patterns were modified ( cigarette smoking χ2 = 4.50 ; altitude toward clinic visit χ2 = 7.09 ; both P＜0. 05 ). Conclusion Health education could help to improve the awareness of health knowledge and modify lifestyle and behavior patterns of migrant workers.

Background: Total knee arthroplasty (TKA) is a common surgical procedure for patients with knee osteoarthritis. The patellar component plays a crucial role in knee biomechanics and can influence postoperative outcomes. This study aimed to investigate the relationship between radiological indices of patellar height and patient outcomes following TKA. Methods: A retrospective analysis was conducted on patients who underwent TKA for osteoarthritis. Radiographic measurements of patellar height, including the Insall-Salvati (IS) ratio, modified Blackburne-Peel (mBP) ratio, Caton-Deschamps ratio, and plateaupatellar angle (PPA), were obtained. Clinical outcomes were assessed using the Knee Society Score (KSS) and the Forgotten Joint Score-12 (FJS-12). Patient satisfaction and postoperative complications were also evaluated. Statistical analyses, including correlation analysis and multiple regression models, were performed to determine the association between radiological indices and patient outcomes. Results: The study included 330 cases that met the inclusion criteria. The analysis revealed significant correlations between different radiological indices of patellar height and patient outcomes. Lower postoperative PPA was correlated with worse KSS and range of motion scores. A decreased mBP ratio was associated with poorer FJS-12 responses and higher risks of dissatisfaction and patellar clunk or crepitus. Increased IS ratio was linked to a lower likelihood of incidental giving way of the knee. Advanced age was associated with reduced dissatisfaction and incidental giving way probabilities. Conclusions The findings of this study demonstrate that radiological indices of patellar height can predict patient outcomes following TKA. Assessing patellar height using various radiographic measurements provides valuable information for surgical planning and prognostic evaluation. Understanding the impact of patellar height on clinical outcomes can aid in optimizing TKA procedures and improving patient satisfaction. These findings emphasize the importance of considering patellar height as a predictive factor in TKA and highlight its potential role in guiding postoperative management and rehabilitation strategies.

Objective:To explore the correlation between clinical classification and genotype and prognosis among Chinese children with Very-long chain acyl-CoA dehydrogenase deficiency (VLCADD).Methods:A Chinese pedigree affected with VLCADD admitted at the First People′s Hospital of Yunnan Province in February 2019 was selected as the study subject. The characteristics of disease onset, diagnosis and treatment and prognosis were retrospectively analyzed. Relevant literature was also systematically searched and reviewed.Results:The proband, a 1-year-old boy, had the clinical manifestations of frequently vomiting, hypoglycemia, abnormal liver function and myocardial enzymes. Tandem mass spectrometry screening showed significantly elevated C14, C14: 1, C16: 1, C16: 2, C18 and C14/C8. Genetic testing revealed that he has harbored compound heterozygous variants of the ACADVL gene, namely c. 664G>A (p.G222R) and c. 1345G>A (p.E449K), which were respectively derived from his father and mother. The child was diagnosed with VLCADD cardiomyopathy type and deceased 2 weeks later. Literature review has identified 60 Chinese children with VLCADD. The clinical classifications were mainly cardiomyopathy type and liver disease type, which accounted for 73.3% (43/60). The combination of ACADVL gene variants were correlated with the clinical classifications of VLCAD. Children with one or two loss-of-function (LOF) mutations showed more severe clinical manifestation and a higher mortality. Cardiomyopathy type had the poorest prognosis, with a mortality rate of 76.9% (20/26). C14: 1 may be used as an indicator for the diagnosis of VLCADD, but cannot be used for clinical subtyping and prognosis evaluation. The c. 1349G>A (p.R450H) variant had the highest frequency among the Chinese patients, accounting for 10.8% (13/120). Conclusion:The clinical classifications of VLCADD are strongly correlated with the prognosis, and LOF mutations are more common in those with severe clinical manifestations. c. 1349G>A (p.R450H) may be the most common variant among the Chinese patients, and early screening and diagnosis can greatly improve the prognosis of patients.

Objective:To reassess the prognostic value of minimal residual disease (MRD) and IKZF1 gene deletions in adults with B-cell acute lymphoblastic leukemia (B-ALL) who received pediatric-specific chemotherapy regimens during the Nanfang Hospital PDT-ALL-2016 trial.Methods:We retrospectively analyzed the prognosis of 149 adult patients with B-ALL who were admitted to Nanfang Hospital from January 2016 to September 2020. Prognostic factors were identified using Cox regression models.Results:The complete remission rate was 93.2% in 149 patients, with a 5-year overall survival (OS) rate of (54.3±5.0) % and a cumulative incidence of relapse (CIR) of (47.5±5.2) %. The Cox regression analysis revealed that MRD positivity at day 45 (MRD 3) after induction therapy was independently associated with relapse risk ( HR=2.535, 95% CI 1.122-5.728, P=0.025). Deletion of IKZF1 gene was independently associated with mortality risk ( HR=1.869, 95% CI 1.034-3.379, P=0.039). Based on MRD 3 and IKZF1 gene status, we categorized adult patients with B-ALL into the low-risk (MRD 3-negative and IKZF1 gene deletion-negative) and high-risk (MRD 3-positive and/or IKZF1 gene wild type) groups. The 5-year OS and CIR rates were (45.5±6.0) % vs (69.4±8.6) % ( P<0.001) and (61.6±8.3) % vs (25.5±6.5) % ( P<0.001), respectively, in the high-risk and low-risk groups, respectively. The multivariate analysis showed that the high-risk group was an independent risk factor for OS ( HR=3.937, 95% CI 1.975-7.850, P<0.001) and CIR ( HR=4.037, 95% CI 2.095-7.778, P<0.001) . Conclusion:The combined use of MRD and IKZF1 gene in prognostic stratification can improve clinical outcome prediction in adult patients with B-ALL, helping to guide their treatment.

Objective To evaluate changes of the urodynamics of extraperitoneal Studer orthotropic ileal neobladder after radical cystectomy.Methods Between July 2013 and October 2017,Retrospective analysis was performed on 58 bladder cancer patients.58 patients who underwent retrograde extraperitoneal approach of radical cystectomy and Studer orthotopic ileal neobladder.The patients were comprised of 56 male and 2 female patients with average age of 62 years.There were 9 cases of T1,26 cases of T2,20 cases of T3,and 3 cases of T4.All operations were completed by open suprapubic extraperitoneal approach,then entered the abdominal cavity.An ileal segment 50-55 cm long was isolated which was 25 cm proximal to the ileocecum.The 35-40 cm ileal segment was detubularized along its antimesenteric border.The anterior wall was folded forward with U-shaped and the edges were sutured to formed a neobladder.The proximal 15cm was reserved for the double isoperistaltic afferent limb.The lowest part of the neobladder was anastomosed with urethral stump,the peritoneum was closed at the mesentery,and the neobladder was completely placed extraperitoneal.Upper urinary tract function was examined by renal function test,enhanced CT,IVU or cystography.Uroflowmetry,urodynamic evaluation,diurnal and nocturnal continence were performed at 3,6,12,24 months following the surgery.Results After removed of the catheter,all patients were able to urinate through the urethra.The 3,6,12,24 month follow-up data of urodynamic were compared.The maximum neobladder capacity was[(378 ±66) vs.(381 ± 102)vs.(438 ± 75)vs.(472 ±96)] ml,the maximum flow rate [(10.2 ± 2.8) vs.(14.9 ± 4.3) vs.(16.4 ± 3.6) vs.(17.6 ± 2.1)] ml/s,maximum bladder pressure during filling was [(23.0 ± 4.6) vs.(21.7 ± 7.1) vs.(20.6 ± 6.4) vs.(18.8 ±6.3)] cmH2 O,the PVR was[(68.0 ± 33.2) vs.(36.2 ± 10.1) vs.(30.6 ± 11.9) vs.(14.0 t 9.6)] ml.There were significant differences between the 6-month and 12-month.There were no significant differences in the maximum bladder pressure during flowing [(38.6 ± 7.4) vs.(49.2 ± 6.8) vs.(58.4 ± 10.5) vs.(56.8 ± 7.4)] cmH2O.53 cases were followed up 12 months after surgery.Excellent daytime and nighttime continence was 98％ (52/53)and 83 ％ (44/53)in the first year.Mild unilateral hydronephrosis occurred in 2 cases 1 month after surgery.Blood electrolytes and renal function were within the normal range.1 case presented bilateral mild hydronephrosis 12 months after surgery,without bladder and ureter regurgitation.The blood electrolyte and renal function of the other patients were in normal range with no signs of ureteral stricture and upper urinary tract hydronephrosis.Conclusions Extraperitoneal Studer orthotopic ileal neobladder reduced the interference of postoperative intraperitoneal intestinal tract on neobladder function.Postoperative patients have a smooth urination,a safe pressure during the storage period.The urination period,and the function of day and night urinary control is close to normal physiological characteristics.

ObjectiveTo reveal the targets and molecular mechanisms of the action of Qiangxin Decoction （强心汤） for the treatment of chronic heart failure based on the combination of network pharmacology and molecular docking. MethodsThe active ingredients of Qiangxin Decoction were retrieved from TCMSP database， and the targets of chronic heart failure were screened by searching GeneCards， OMIM， TTD， PharmGkb， and DrugBank databases， and the intersections were taken to obtain the intersecting targets of Qiangxin Decoction for the treatment of chronic heart failure. STRING platform was used to construct the protein-protein interaction network （PPI）， Cytoscape 3.8.0 software was used to calculate the network topology to screen the core targets， and R 4.2.3 was used to construct the “active ingredient-target” network by analyzing the GO enrichment analysis and KEGG pathway enrichment analysis. AutoDock 1.5.7 was used for molecular docking to predict the binding performance of active ingredients and core targets. ResultsSeventy-five intersecting targets were identified for the treatment of chronic heart failure with Qiangxin Decoction， among which the core targets were estrogen receptor 1 （ESR1， degree value=7）， nuclear receptor coactivator 1 （NCOA1， degree value=8）， glucocorticoid receptor （NR3C1， degree value=7）， and nuclear receptor coactivator 2 （NCOA2， degree value=7）. GO enrichment analysis showed that the top 3 items with the smallest P value in molecular function were G protein-coupled amine receptor activity， postsynaptic neurotransmitter receptor activity， and neurotransmitter receptor activity （P＜0.01）； the top 3 items with the smallest P value in biological process were adenylyl cyclase-activated adrenergic receptor signaling pathway， adrenergic receptor signaling pathway， and adenylyl cyclase-regulated G protein-coupled receptor signaling pathway （P＜0.01）； the top 3 items with the smallest P values in cellular composition were components of the postsynaptic membrane， synaptic membrane， and presynaptic membrane （P＜0.01）. KEGG enrichment analysis showed that the top 5 key signaling pathways were neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， cocaine addiction， and cyclic guanosine monophosphate-protein kinase G （cGMP-PKG） signaling pathway. The molecular docking results showed that lignans and isoflavones had lower binding energies and more structural stability with the four core targets （ESR1， NCOA1， NR3C1， NCOA2）. ConclusionThe treatment of chronic heart failure by Qiangxin Decoction was associated with neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， chemoattractant-receptor activation， cGMP-PKG signaling pathway， lipids and atherosclerosis， and cAMP signaling pathway， and lignans and isoflavones may be the core active compounds in its treatment of chronic heart failure.
