ObjectiveTo explore the effect of respiratory training based on core stabilization training on lumbar disc herniation. MethodsFrom January, 2023 to October, 2024, 96 patients with lumbar disc herniation admitted to the First Affiliated Hospital of Bengbu Medical University were divided into control group (n = 32), core group (n = 32) and respiratory group (n = 32). All the groups underwent conventional rehabilitation therapy, with core stabilization training in the core group and respiratory training combined with core stabilization training in the respiratory group, additionally, for four weeks. Before and after training, the scores of Visual Analogue Scale, Japanese Orthopaedic Association (JOA) and Oswestry Dysfunction Index (ODI) were compared, the average electromyographic value (AEMG) and root mean square (RMS) value of the multifidus and transversus abdominis were detected by surface electromyography (sEMG); and the thickness of the multifidus and transversus abdominis were measured by musculoskeletal ultrasonography bilaterally. ResultsThe intra-group effect (F > 597.796, P < 0.001), inter-group effect (F > 16.535, P < 0.001) and interaction effect (F > 49.622, P < 0.001) were significant in the scores of VAS, JOA and ODI; which were better in the respiratory group than in the control group and the core group (P < 0.05), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 7971.631, P < 0.001), inter-group effect (F > 177.760, P < 0.001) and interaction effect (F > 478.771, P < 0.001) were significant in the thickness of the transversus abdominis and multifidus; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 144303.007, P < 0.001), inter-group effect (F > 1495.458, P < 0.001) and interaction effect (F > 3121.361, P < 0.001) were significant in the RMS of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 1890.532, P < 0.001), inter-group effect (F > 607.132, P < 0.001) and interaction effect (F > 824.923, P < 0.001) were significant in the AEMG of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). ConclusionCore training combined with respiratory training can more effectively reduce pain and improve dysfunction by enhancing the strength and control of the core muscles， thus improving the quality of life of patients with lumbar disc herniation.

Objective To explore the clinical efficacy of transcranial combined peripheral magnetic stimu-lation on bladder and voiding ability in patients with NB after spinal cord injury.Methods From September 2023 to October 2024,60 patients with NB after spinal cord injury were chosen from the Department of Rehabilitation Medicine of the First Affiliated Hospital of Bengbu Medical University,and were separated into the regular group(n=15),M1 area stimulation group(n=15),sacral nerve root stimulation group(n=15),and combined stimulation group(n=15).The control group underwent conventional rehabilitation treatment,the M1 area stimu-lation group added repetitive transcranial magnetic stimulation(rTMS)of the M1 area of the motor cortex,the sacral nerve root stimulation group added repetitive peripheral magnetic stimulation(rPMS)of the sacral 3 nerve roots,and the co-stimulation group added rTMS of the M1 area and rPMS of the sacral 3 nerve roots,and the treat-ment was carried out for 4 weeks in total.Urodynamic indices,voiding diaries,and neurogenic bladder symptom scores(NBSS)were assessed before and after therapy in the four groups.Results Before therapy,the differences in maximum bladder capacity,bladder capacity at the time of the first urge to urinate,maximum urine flow rate,residual urine volume,average number of urination per day,average daily urinary output,and NBSS scores of the four groups were not statistically significant when compared with those of the pre-treatment group(P<0.05);after treatment,the maximum bladder capacity,bladder capacity at the time of the first urge to urinate,maximum urine flow rate,residual urine volume,average number of urination per day,average daily urinary output,and NBSS scores were all improved compared with those before treatment(P<0.05);in comparison between the groups,after treatment,the Urodynamic indices,voiding diaries,and NBSS scores of the combined group were better than those of the other three groups(P<0.05).Conclusion Transcranial combined peripheral bidirectional feedback magnetic stimulation therapy can improve urodynamic and voiding symptoms and promote the recovery of bladder and voiding function in patients with NB after spinal cord injury

Objective : To construct a molecular classification system for head and neck squamous cell carcinoma (HNSCC) utilizing hypoxia-related gene (HAG) expression profiles, and to comprehensively examine the clinicopathological significance and biological functions of the hypoxia gene stanniocalcin 2 (STC2) in HNSCC. Methods : Transcriptomic data and clinical information of 546 HNSCC samples were obtained from The Cancer Genome Atlas (TCGA) database, and based on the expression profiles of 200 HRGs, HNSCC was classified subclasses using non-negative matrix factorization (NMF). HNSCC was classified into three subclasses (C1, C2, and C3), and the molecular characteristics and prognostic differences of the subclasses were assessed by comparing the tumor mutation load, functional enrichment analysis, drug sensitivity, and clinical features among the subclasses. LASSO-Cox regression was used to screen prognosis-related genes and construct prognostic models. Using oral squamous cell carcinoma (OSCC)-related data in the TCGA database, we analyzed the expression differences of STC2 in OSCC and control samples, and detected the mRNA and protein expression of STC2 in oral squamous carcinoma samples using qRT-PCR and immunohistochemistry. We knocked down STC2 in CAL-27 cells and verified the knockdown efficiency by qRT-PCR and Western blot. CCK-8 assay and cell scratch assay were used to assess the effect of STC2 on cell proliferation and migration ability. Results: Based on HRGs expression profiles, HNSCC was categorized into three subclasses (C1, C2, and C3). Subclass C1 had moderate hypoxic activity and good prognosis; subclass C2 had the highest hypoxic activity, poor prognosis, and poor sensitivity to CTLA-4 inhibitors (P<0.05); subclass C3 had the lowest hypoxic activity and moderate prognosis, and STC2 belonged to subclass C3. The frequency of cyclin-dependent kinase inhibitor 2A (CDKN2A), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and tumor protein p53 (TP 53) mutations was higher in HNSCC. C1 genomic gain and deletion burden were significantly higher than C3 subclass (P<0.05) and C2 genomic gain than C3 subclass (P<0.05). The C2 subclass was significantly enriched in hypoxia-associated pathways, such as glycine metabolism and base excision repair (P<0.05). The C1, C2, and C3 subclasses were significantly positively correlated in terms of sex (male) (Cramer’s V=0.15), radiation exposure (Cramer’s V=0.12), medication (Cramer’s V=0.18), and pathological grading (G1/G2) (Cramer’s V=0.25) (P<0.05). Nine prognosis-related genes were screened by LASSO-Cox regression, among which high expression of STC2 was positively correlated with poorer overall survival (OS) in HNSCC patients (P<0.01). Bioinformatics analysis showed that STC2 mRNA expression was higher in OSCC than in normal controls (P<0.05). qRT-PCR and immunohistochemistry confirmed that both mRNA and protein expression of STC2 were significantly upregulated in OSCC tissues and cells (P<0.01). In vitro experiments showed that STC2 expression was knocked down to approximately 80% in CAL-27 cells (P<0.001), and the STC2 knockdown group had a reduced value-added rate (P<0.001) and a reduced percentage of scratch closure (P<0.05) compared with the control group. Conclusion We successfully constructed a molecular typing system for HNSCC based on the expression profiles of HRGs and categorized HNSCC into three subclasses with significant prognostic differences, among which the C2 subclass had the highest hypoxic activity and the poorest prognosis. STC2 was highly expressed in HNSCC and suggested a poor prognosis, demonstrating that it may be a potential target for HNSCC treatment.

Objective To explore the effect of robotic training under position limitation on upper limb of patients with shoulder sub-luxation after stroke. Methods From March to December,2023,sixty patients with shoulder subluxation after stroke in the First Affiliated Hospital of Bengbu Medical University were randomized into conventional group(n = 20),robot group(n = 20)and position-limited group(n = 20).All the groups accepted conventional rehabilitation,while the robot group underwent robot training and the position-limited group underwent robot training under position limitation,for four weeks.Before and after treatment,Fugl-Meyer Assessment-Upper Extremities(FMA-UE)and modified Bar-thel Index(MBI)were used for evaluation,surface electromyography(sEMG)was used to measure the average electromyography(AEMG)and root mean square(RMS)of posterior deltoid fasciculus and supraspinatus during contraction,and musculoskeletal ultrasonography was used to determine the distance of acromion-greater tuber-osity(AGT)of the affected side. Results After treatment,FMA-UE score,MBI score,AEMG,RMS and the distance of AGT improved in all the groups(|t|>10.850,P<0.001),and all the indexes were optimal in the position-limited group(F>42.031,P<0.001). Conclusion Robotic training for upper limb under postural limitation can further improve upper limb function and sub-luxation status,activities of daily living,and peri-shoulder muscle in patients with shoulder subluxation after stroke.

Purpose To investigate the features of conventional and contrast-enhanced ultrasound (CEUS) imaging in renal epithelioid angiomyolipoma (EAML). Materials and Methods We retrospectively analyzed the conventional ultrasound and CEUS images of the 30 patients with renal EAML who were confirmed by pathology in the General Hospital of the PLA from November 2010 to October 2022. The location,size,classfication,echo,boundary,shape,growth pattern and whether color Doppler ultrasound detects blood flow signals were observed by conventional ultrasound. CEUS was used to analyze the wash-in pattern,enhancement direction,peak enhancement intensity,the uniformity after enhancement,wash-out pattern and pseudocapsule sign,respectively. Results A total of 30 patients (n=30 lesions) were enrolled. The maximal diameter of the lesions varied from 1.4 to 12.6 cm. 17 cases occurred in the right kidney and 13 cases in the left kidney. On grayscale ultrasound,28 cases showed solid type,2 were cystic solid;18 cases demonstrated hypoechoic,10 were hyperechoic;the solid component in the cystic solid lesion was isoechoic in 1 case and hyperechoic in 1 case;24 cases displayed well-defined and 19 cases appeared regular shape;22 cases were presented exophytic growth. Color Doppler ultrasound detected blood flow in 24 cases. Of all 30 patients with EAML,CEUS was performed in 13 cases,6 lesions with simultaneous wash-in;10 cases with centripetal enhancement;9 cases with hyper-enhancement;10 cases with homogeneous enhancement;5 lesions with simultaneous wash-out;9 cases with pseudocapsule sign. Conclusion The ultrasonographic appearance of EAML has a tendency to be hypoechoic with exophytic growth and clear boundary on conventional ultrasound images,and centripetal enhancement,homogeneous hyperenhancement and presence of pseudocapsule on CEUS images. All these findings are contributed to the diagnosis of EAML.

Objective:To mine the adverse events (AE) risk signal of azithromycin in children, establish the corresponding pharmaceutical care process, and provide reference for the safe use of azithromycin in clinic.Methods:AE caused by azithromycin in children (<18 years) were searched from the US FDA Adverse Event Reporting System (FAERS) database from the 1st quarter of 2004 to the 4th quarter of 2023. The AE was standardized and classified using the preferred term (PT) and system organ class (SOC) in the Medical Dictionary for Regulatory Activities 26.1 version. Reporting odds ratio (ROR) and proportional reporting ratio (PRR) methods were used for detection of AE signal of azithromycin. AE that simultaneously met the following conditions was considered as a risk signal: the number of reports≥3, lower limit of the 95% confidence interval of ROR≥1, PRR>2, and χ2>4. Descriptive analysis on the signals was performed. The pharmaceutical care process of azithromycin for children was established based on the results of signal mining and satisfaction survey was conducted. Results:A total of 1 457 AE reports related to azithromycin in children were collected, involving 127 PTs and 18 SOCs. The top 5 PTs in the number of reports were rash, pruritus, urticaria, drug hypersensitivity and diarrhea. The top 5 PTs in signal intensity were infantile diarrhea, myasthenia gravis crisis, intermittent explosive disorder, diarrhea neonatal, and infantile vomiting. A total of 16 risk signals that were not recorded in the label were mined out, and the top 5 PTs according to signal intensity were intermittent explosive disorder, conversion disorder, bronchiectasis, tooth discoloration, and choreoathetosis. The analysis of 79 AE reports with death outcomes showed that drug-induced liver injury, Stevens-Johnson syndrome, rash, vomiting, nausea, cyanosis, and diarrhea were related risk signals. Based on the signal mining results mentioned above, the medication safety officer team in our hospital established a pharmaceutical care process of azithromycin application for children, including pre-medication assessment (indications, medical history, heart and liver function, etc.), speed and mode of administration monitoring during the medication, and intervention measures after the occurrence of adverse reactions, and 178 hospitalized children who received azithromycin treatment were monitored. The satisfaction survey results showed the degree of satisfaction was 100%.Conclusions:The main AEs related to azithromycin in children are rash, pruritus, urticaria, drug hypersensitivity, and diarrhea, all of which are recorded in the label. In addition, we should also be vigilant against the risk signals such as intermittent explosive disorder, conversion disorder, bronchiectasis, tooth discoloration, and choreoathetosis, which are not recorded in the label. The pharmaceutical care process for azithromycin use in children based on the risk signal mining results is feasible and effective.
