Objective To explore the impact of the clinical internship model at the on-campus rehabilitation outpatient clinic on the clinical practice abilities and employment intentions of students in the physical therapy program.Methods A total of 60 students from the 2020 cohort of the Rehabilitation Physical Therapy program at Kunming Medical University were selected as research subjects.In the first semester of their sophomore year,they were randomly divided into two groups:the three-phase clinical internship group at the on-campus rehabilitation outpatient clinic(n=30)and the conventional clinical internship group(n=30).The three-phase clinical internship group completed their clinical internship in three phases according to the training objectives at the on-campus rehabilitation outpatient clinic,while the conventional clinical internship group completed their internship according to the requirements of the internship syllabus.At the end of all clinical internships,assessments were conducted using a comprehensive theoretical examination of core professional courses,the Assessment of Physiotherapy Practice(APP),and an employment intention survey to evaluate the outcomes of the internships for both groups.Results After completing all internship tasks,there was no statistically significant difference in the scores of the comprehensive theoretical examination of core professional courses between the two groups(P>0.05).Similarly,there was no statistically significant difference in the total scores of the physiotherapy clinical practice assessment between the two groups(P>0.05).However,in the detailed assessments,the three-phase internship group outperformed the conventional group in professional behavior,communication,and evaluation(P<0.05).There were no statistically significant differences between the two groups in analysis and planning,intervention,evidence-based practice,and risk management(P>0.05).In the employment intention survey,70%of students in the three-phase internship group expressed a willingness to work in rehabilitation outpatient clinics or clinics,while only 46.6%of the conventional group did so.The comparison of employment intentions between the two groups showed a statistically significant difference(P<0.05).Conclusion The three-phase apprenticeship model of the on-campus rehabilitation clinic not only improves students'clinical practice ability,but also increases their confidence in seeking employment in the rehabilitation clinic,thus broadening the employment pathway for physiotherapy students.

Objective To explore the immediate,long-term,and delayed effects of spiral stabilizing muscle chain technique compared to static distraction and Proprioceptive Neuromuscular Facilitation(PNF)stretching techniques on the flexibility of hip flexors.Methods Ninety subjects were randomly divided intothree groups of 30 each.Group 1 underwent the static stretching of the hip joint.Group 2 received PNF stretching,and Group 3 participated in SPS training.All participants were measured for hip extension angle to assess hip flexor flexibility before training,immediately after the first training session,at the end of 4 weeks of training,and 2 weeks after training cessation.Results Within-group comparisons showed significant increases in hip extension angles after one training session,after 4 weeks of training,and after 2 weeks of cessation compared to pre-training(P＜0.05).Between-group comparisons indicated no statistically significant differences in hip extension angle improvements among the three groups after one training session,after 4 weeks of training,and after 2 weeks of cessation(P＞0.05).Conclusion SPS training,static stretching,and PNF stretching all demonstrate good immediate,long-term,and delayed effects on improving hip extension angles,with consistent stretching outcomes.

Objective To assess the application value of mycoplasma pneumonia(MP)real-time fluorescence of RNA simultaneous amplification and testing(SAT)and MP antibody(MP-Ab)in the diagnosis of MP pneumonia(MPP)in children.Methods A total of 242 children with community-acquired pneumonia hospitalized at Beijing Haidian Hospital from September 2023 to October 2024 were enrolled as subjects.The children were divided into MPP group(n=193)and non-MPP group(n=49)based on MPP diagnosis.All children underwent simultaneous MP-SAT testing and initial MP-Ab detection within 24h of admission.MP-SAT results were monitored until they turned negative,with retesting for MP-Ab on 5-7d post-hospitalization in negative cases.The study compared diagnostic accuracy between MP-SAT and MP-Ab methods,while analyzing correlations between MP-SAT negative conversion time and clinical cure duration.Results For children with disease duration ≤ 7 days,MP-SAT demonstrated higher sensitivity than MP-Ab,with statistically significant difference(P＜0.001).The concordance between MP-SAT and initial MP-Ab test results was weak(Kappa=0.072),while the consistency between MP-SAT and follow-up MP-Ab test results was moderate(Kappa=0.614,P＜0.00 1).Both the clinical cure time and SAT seroconversion time were shorter with doxycycline treatment compared to azithromycin therapy.Conclusion The results of MP-SAT can be used to evaluate the condition of MPP children and guide the timely discontinuation of antibiotics.

Objective:To analyze the pathogenicity and clinical phenotype associated with a newly identified heterozygous variant in the ZEB1 gene that causes posterior pleomorphic corneal dystrophy (PPCD). Methods:A pedigree study was conducted.Clinical data of four people in 2 generations from one family with PPCD who visited Henan Eye Hospital in October 2023 were collected, including 3 patients. Relevant ophthalmic examinations were performed.Best corrected visual acuity, slit lamp microscopy, intraocular pressure, Pentacam corneal topography, Corvis ST corneal biomechanics analyzer, corneal endothelial microscopy, swept-source anterior segment coherence optical tomography (CASIA), laser scanning confocal microscopy, and ultra-wide-field fundus photography were performed to examine clinical phenotypes.Peripheral venous blood samples were collected from family members to extract genomic DNA, and whole exome sequencing was performed.Sanger sequencing and pedigree co-segregation analysis were carried out.Conservation analysis was performed using GERP+ + and Clustal Omega software, and the pathogenicity of the variant was assessed according to American College of Medical Genetics and Genomics (ACMG) guidelines.This study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[15]).All subjects or guardian signed informed consent.Results:This family conformed to autosomal dominant inheritance.Under a slit-lamp microscope, corneal endothelial vesicular lesions in both eyes could be seen in the proband, her father and her brother.Under a laser scanning confocal microscope, endothelial cells were missing at the lesions, and some were crater-like changes, and some lesions were circular or elliptical vesicular, and no other systemic abnormalities were observed.The ocular and physical examination of the proband's mother showed no abnormalities.Genetic testing results showed that the proband, her father and her brother all carried the ZEB1c.790G>A (p.Gly264Arg) heterozygous variant, but her mother did not carry the variantion.Sanger sequencing verified that this variantion was co-segregated within the family.The variantion is a newly discovered missense mutation that had not been reported in the Thousand Genomes Project, Genome Aggregation Database, and ExAC database.The prediction results of the variant by MutationTaster, SIFT, PROVEAN, VESST3, DANN, FATHMM-MKL, CADD, fitCons and other software were harmful, and GERP+ +, Weblogo, Clustal Omega analysis showed that the amino acids affected by the variant were highly conservative.According to the ACMG Guidelines, this variation was possible pathogenic.Conclusions:The identification of the missense mutation c. 790G>A (p.Gly264Arg) in the ZEB1 gene within this PPCD family provides new insights into the genetic basis of PPCD and the variant may be the pathogenic variant of in this family.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective To explore the effects and therapeutic mechanism of electroacupuncture on the levels of polarization markers and inflammatory factors interleukin(IL)-6,IL-4,tumor necrosis factor-alpha(TNF-α),and IL-10 in rats with para-chlorophenylalanine-induced insomnia(PCPA).Methods Fifty healthy specific-pathogen free grade Sprague-Dawley rats,half male and half female,were randomly divided into a blank group(n=10)and a model reserve group(n=40),in which insomnia was induced by intraperitoneal injection of a 500 mg/kg PCPA suspension.Using the random number table method,the 30 successfully modeled rats were divided into three treatment groups of 10 rats/group:model,electroacupuncture,and estazolam.The estazolam group was given estazolam 0.2 mg/(kg·d)by gavage;the electroacupuncture group was given once-daily electroacupuncture at the"Shenmen"and"Sanyinjiao"acupoints,and stimulation at the"Baihui"and"Benshen"acupoints,20 minutes each time,for 7 consecutive days.Following treatment,serum and hypothalamic levels of TNF-α,IL-6,IL-4,and IL-10 were detected using ELISA and Western blot,while immunofluorescence staining was used to detect the presence of Iba-1 in hypothalamic microglia and the co-expression of CD86 and CD163,which are markers for the M1 and M2 subtypes of microglial cells,respectively.Results Compared with the blank group,the model group exhibited prolonged sleep latency(SL)(P＜0.01),shortened sleep duration(ST)(P＜0.05),significantly higher serum and hypothalamic protein levels of IL-6 and TNF-α(P＜0.01),and significantly lower levels of IL-4 and IL-10(P＜0.01).Compared with the model group,the electroacupuncture and estazolam groups exhibited significantly shorter SL(P＜0.01),prolonged ST(P＜0.01),significantly lower serum and hypothalamic protein levels of IL-6 and TNF-α(P＜0.01),and significantly higher IL-4 and IL-10 levels(P＜0.01).IL-6 content was lower in the electroacupuncture group than in the estazolam group(P＜0.05).Compared with the blank group,the model group exhibited significantly enhanced Iba-1/CD86(M1 type)co-expression(P＜0.01)alongside significantly weakened Iba-1/CD163(M2 type)co-expression(P＜0.01).Under electroacupuncture or estazolam intervention,Iba-1/CD86 co-expression was significantly weakened(P＜0.01),and Iba-1/CD163 co-expression was significantly enhanced in the model group(P＜0.05).Conclusions Electroacupuncture effectively improved sleep disturbances in rats,with an underlying mechanism that may involve regulation of microglial polarization,downregulation of pro-inflammatory cytokine levels,upregulation of anti-inflammatory cytokine levels,and alleviation of neuroinflammation,thereby ameliorating sleep.

Objective:To investigate the clinical application value of cystatin C(CysC), neutrophil gelatinase-associated lipocalin(NGAL), urea nitrogen(UREA), blood creatinine(Scr)and urinary neutrophil gelatinase-associated lipocalin(NGAL)in early diabetic nephropathy and their relationship with aging.Methods:A total of 140 diabetic patients aged 60 and above who were admitted to Beijing Hospital from July 2022 to November 2022 and 59 healthy people aged 60 and above who underwent physical examination in Beijing hospital during the same period were selected as the study subjects.In January 2023, 157 healthy people over 20 years old who underwent physical examination in Beijing Hospital were used as another group of research objects to explore the relationship between various indicators and aging.According to the urinary microalbumin/urinary creatinine(UACR)ratio, the patients were divided into three groups: 40 patients with simple diabetes mellitus(DM), 57 patients with early diabetic nephropathy(EDN), and 43 patients with diabetic nephropathy(DN).59 healthy subjects were used as control group(NC group).Serum NGAL, Scr, Cys C, UREA and urinary NGAL were detected, and NGAL was determined by latex immunoturbidimetry.Scr was determined by sarcosine oxidase method.Cys C was determined by immunoturbidimetry.Urease-glutamate dehydrogenase method was used to determine UREA.Receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of urea alone and combined diagnosis in EDN.The relationship between serum NGAL, Scr, Cys C, UREA and urinary NGAL and gender and aging were analyzed in 157 healthy individuals.Results:Compared to the NC group, serum NGAL, Scr, CysC, and UREA levels were significantly higher in the EDN and DN groups(all P<0.01), and the differences between EDN group, DN group and NC group were statistically significant( P<0.01).The values of these markers increased across the NC, DM, EDN, and DN groups.ROC curve shows: The area under curve(AUC)of serum NGAL, Scr, Cys C, UREA, urine NGAL, combined diagnosis 1 and combined diagnosis 2 were 0.655, 0.760, 0.789, 0.753, 0.628, 0.831, 0.827, respectively.The sensitivity of combined diagnosis 1 and combined diagnosis 2 was higher(63.2% and 66.7%), and the specificity of serum NGAL was higher(96.6%).The AUC values of Cys C, co-diagnosis 1, and co-diagnosis 2 were large and correlated(AUC=0.789, 0.831, 0.827, rs=0.501, 0.573, 0.567), and the diagnostic value of Cys C, co-diagnosis 1, and co-diagnosis 2 for EDN was high(AUC=0.789, 0.831, 0.827, Yoden index=0.442, 0.530, 0.531; sensitivity 56.1%, 63.2%, 66.7%; specificity 88.1%, 89.8%, 86.4%).Healthy individuals over 20 years of age: serum NGAL[(127.5±35.5)μg/L vs.(111.5±32.4)μg/L, P=0.004], Scr[(83.4±11.2)μmol/L versus(63.4±11.0)μmol/L, P<0.001], Cys C[(0.8±0.2)mg/L vs.(0.7±0.2)mg/L, P<0.001], and UREA levels were higher in males than females[(5.1±1.1)mmol/L vs.(4.6±1.1)mmol/ L, P=0.002]; urinary NGAL was higher in females than males[22.0(13.0, 37.8)μg/L vs.15.0(10.0, 30.5)μg/L, P=0.025].Cys C( F=16.582, P<0.001), urinary NGAL levels( F=-3.533, P<0.001)basically increased with age. Conclusions:CysC showed a higher diagnostic value for EDN than UREA, Scr, blood NGAL, and urine NGAL in patients aged 60 and above Combined diagnosis 1 and combined diagnosis 2 have higher value in monitoring the progress of DN.The levels of Cys C and urinary NGAL showed a gradually increasing trend with the increase of age, and the levels of serum NGAL, Scr, Cys C and UREA were higher in males than in females.Urinary NGAL was higher in females than males.

Objective:To compare the clinical and laboratory characteristics and survival between Chinese and Western patients with myelodysplastic neoplasms (MDS) .Methods:Clinical and laboratory data were collected from 1,464 primary adult patients diagnosed with MDS at the Institute of Hematology & Blood Diseases Hospital from August 2016 to June 2024. Collected data were retrospectively analyzed and compared with 2,191 patients from the International Working Group for the Prognosis of Myelodysplastic Syndromes (IWG-PM) .Results:Chinese patients were significantly younger (median age: 56 years vs. 72 years, P<0.001) and experienced more severe hematopenia ( P<0.001) compared with patients from the IWG-PM. Further, Chinese patients exhibited a higher percentage of isolated del (20q), +8, and complex karyotypes as well as a lower percentage of normal karyotypes, del (5q), and -Y ( P<0.001). Higher U2AF1, NRAS, and NPM1 mutation rates and lower ASXL1, SF3B1, and RUNX1 mutation rates were observed in Chinese patients than in participants from the IWG-PM ( P<0.05). No significant difference in overall survival (OS) was found between the two groups (median OS: 48 [95% CI: 40 - 56]months, vs. 45[95% CI: 40 - 49] months; P=0.449). Among participants aged ≤45 years, Chinese patients demonstrated more trisomy 8 ( P=0.070) and U2AF1 mutation ( P<0.001) and higher 4-year OS rate compared with those from the IWG-PM (75.5% vs. 62.1%, P=0.001). Among participants aged ≥70 years, Chinese patients exhibited more complex karyotypes but fewer del (5q) as well as more NPM1 but less SF3B1 and TET2 compared with those from the IWG-PM ( P<0.05). Chinese patients demonstrated shorter survival (median OS: 20 [95% CI: 13 - 27] months vs. 37 [95% CI: 32 - 42] months, P<0.001) . Conclusion:Chinese and Western MDS patients differ in age of onset, clinical features, and cytogenetic or molecular genetic abnormalities, with significant differences persisting in age-matched groups. Although the OS is similar, disparities exist in survival for younger and older patients between the two populations.
