The presence of high-level talents plays a crucial role in ensuring the successful establishment of national regional medical centers.It presents the high-level talent management experience of Henan Children's Hospital,aiming to facilitate the coordinated development of pediatrics in Central China.To address the practical challenges and difficulties encountered in high-level talent management within hospitals,lean talent management is achieved by standardizing the management structure,clarifying management objectives,refining the management mechanism,establishing a performance appraisal incentive system,and implementing an integrated'induction and utilization'management approach.These measures effectively facilitate the development of national children's regional medical centers.

Objective To study the characteristics of spontaneous speech pauses in individuals with mild to moderate Alzheimer's disease(AD).Methods A total of 20 patients with AD,exhibiting a Minimum Mental State Examination(MMSE)score ranging from 10 to 20 and a disease duration of 6 months to 5 years,were selected for the AD group.Twenty five cognitively normal and mentally healthy participants were chosen as the control group.Spontaneous speech was elicited from each participant,and 1-minute continuous audio recordings were used to tally pause counts categorized by duration into short pauses(0.25 s≤t＜0.50 s),medium pauses(0.50 s≤t＜0.90 s),long pauses(0.90 s≤t＜2.00 s),and silences(＞2.00 s).Mean values of each pause type were computed for in-ter-group and intra-group comparisons.Correlation and regression analyses between MMSE scores and pause counts were conducted within the AD group.Results Significant statistical differences were observed between the AD and control groups concerning the counts of short pauses,long pauses,and silences(P＜0.05).Within the AD group,significant differences were found in the counts of short pauses versus medium pauses and short pauses versus long pauses(P＜0.05).In the AD group,the count of medium pauses positively predicted MMSE scores(β=0.515,P＜0.05),whereas the count of silences negatively predicted MMSE scores(β=-0.626,P＜0.01).Conclusion Individuals with AD exhibit a higher frequency of longer duration pauses in spontaneous speech and a lower frequen-cy of shorter duration pauses.Higher cognitive functioning in AD patients is associated with increased occurrences of shorter pauses,whereas lower cognitive functioning is linked to more extended pauses.

Professor Li Candong puts forward the"five differentiation"thinking in TCM:symptom differentiation,syndrome differentiation,disease differentiation,person differentiation and mechanism differentiation.This article discussed the thinking and method of application of classical prescriptions based on the mode of"five differentiation".Treatment based on symptom differentiation is a quick method of application of classic prescriptions,which includes searching for specific symptoms or symptom groups and according to special tongue images.Treatment based on syndrome differentiation is a commonly used method in classic prescriptions,distinguishing between primary and secondary syndromes and the authenticity of cold and heat.Treatment based on disease differentiation is the inherent meaning of classic prescriptions,which is mainly to distinguish six meridian diseases and special prescriptions for specific diseases.Treatment based on person differentiation embodies the individual differences in the use of classic prescriptions,which include age,gender,constitution and abdominal syndrome.Treatment based on mechanism differentiation is an ingenious method used by classic prescriptions.When practicing clinical medicine,we should adhere to the integrated mode of"five differentiation"in the application of classic prescriptions,comprehensively considering the five dimensions,in order to improve the accuracy and effectiveness of the application of classic prescriptions,reveal and improve the academic system of classic prescriptions,and better guide their clinical application.

Objective:To observe the clinical efficacy of auricular needle-embedding therapy for treating primary insomnia. Methods:A total of 63 patients were randomly divided into a conventional acupuncture group and an auricular needle-embedding group.The conventional acupuncture group received acupuncture at meridian points,while the auricular needle-embedding group received acupuncture at auricular points.Treatments were given once a day for 6 consecutive days,followed by a 1-day break,as a course of treatment.Both groups were treated for 2 courses.Before treatment,and after 1 course and 2 courses of treatment,the Pittsburgh sleep quality index(PSQI)score was assessed,and the efficacy was evaluated. Results:The cured and markedly effective rate and total effective rate of the auricular needle-embedding group were higher than those of the conventional acupuncture group,but there was no significant difference between the two groups(P>0.05).After 1 course of treatment,the PSQI global score and the scores of subjective sleep quality,sleep latency,sleep duration,habitual sleep efficiency,and daytime dysfunction of both groups decreased compared with those before treatment(P<0.01);there was no statistical significance in comparing the PSQI global score and individual component scores between the two groups(P>0.05).After 2 courses of treatment,the PSQI global score and the scores of sleep latency and habitual sleep efficiency of the auricular needle-embedding group decreased compared with those after 1 course of treatment(P<0.01 or P<0.05),while only the score of sleep latency of the conventional acupuncture group decreased compared with that after 1 course of treatment(P<0.05);the PSQI global score and the scores of subjective sleep quality and sleep latency of the auricular needle-embedding group were lower than those of the conventional acupuncture group(P<0.05). Conclusion:Both therapies can improve insomnia.Compared to conventional acupuncture,auricular needle-embedding therapy demonstrates a therapeutic advantage in improving sleep latency and sleep quality,making it worthy of clinical promotion.

Objective To analyze the clinical phenotypes and mutation types of children with X-linked Alport syndrome(XLAS)with mutations in COL4A5 gene,and to explore the relationship between children with XLAS and nephrotic syndrome nephritic type.Methods Thirty-two children with COL4A5 gene mutations detected by second-generation sequencing and finally diagnosed with Alport syndrome at Guangzhou Red Cross Hospital affiliated with Jinan University and the First People's Hospital of Guangzhou between April 2016 and April 2023 were included,and their clinicopathological features and gene mutation characteristics were retrospectively analyzed.Results The mean age of onset of disease in children with XLAS was(3.68±2.07)years old,the mean age at diagnosis(6.56±2.95)years old,12 cases(37.5%)started with isolated hematuria,8 cases(25%)started with hematuria and proteinuria,12 cases(37.5%)started with nephrotic syndrome nephritic phenotype,and the positive family history of the children was found in 11 cases(34.4%),ocular lesions were found in 3 cases(9.37%),ear lesions in 6 cases(18.75%),and 7 cases(21.87%)were found to have developed chronic kidney disease(CKD)in the later follow-up.21 children underwent renal tissue puncture biopsy,and electron microscopy showed thinning of the basement membrane(diffuse or segmental)in 13 cases(61.9%),and uneven thickness of the basement membrane in 8 cases(38.09%);light microscopy showed thinning of the basement membrane in 13 cases(61.9%);light microscopy showed thinning of the basement membrane in 8 cases(38.09%);and light microscopy showed thinning of the basement membrane in 3 cases(11.5%).(38.09%);light microscopy:focal segmental glomerulosclerosis(FSGS)in 2 cases(9.52%),mesangial proliferative glomerulonephritis(Ms PGN)in 11 cases(52.38%),and minimal change disease(MCD)in 8 cases(38.09%).The type of mutation was categorized as missense mutation in 12 cases(37.5%),shear site mutation in 9 cases(28.12%),nonsense mutation in 6 cases(18.75%),deletion mutation in 3 cases(9.37%),and code shift mutation in 2 cases(6.25%).Genetic mutations were present in 22 cases(68.75%);spontaneous mutations were present in 10 cases(27.02%).Conclusions Children with XLAS have atypical clinical manifestations and pathologic features in the early stage of the disease,and the progress is slow,and some of them are easy to be misdiagnosed as nephrotic syndrome nephritis type in the early stage,so it is important to improve the genetic test for this disease as early as possible,and to make reason-able drug choices to predict the prognosis scientifically.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To summarize the clinical phenotype and genetic characteristics of Poirier-Bienvenu neurodevelopmental syndrome associated with CSNK2B gene variation. Methods:The clinical and genetic data of a child with Poirier-Bienvenu neurodevelopmental syndrome caused by shear variant of CSNK2B gene who was diagnosed in the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University in March 2022 were collected. Previous relevant literature at home and abroad was reviewed to summarize the clinical characteristics of the disease. Results:The child was a girl aged 13 months, mainly due to "intermittent convulsions for 2 months" for consultation. The clinical manifestations of the girl were normal face, generalized tonic-clonic seizures, low intelligence, language and motor retardation, and there was no abnormality in the long-range video electroencephalography and the head magnetic resonance imaging. No abnormality was found in chromosome karyotype analysis and chromosome coefficient of copy variation analysis. The whole exon gene sequencing test indicated that the child carried de novo heterozygous shear variant of CSNK2B gene c.291+5G>C, which had not been reported in the literature. According to the clinical manifestations and genetic examination results of the child, the diagnosis of Poirier-Bienvenu neurodevelopmental syndrome was clear. The CSNK2B gene of the proband′s parents and the twin sister was wild-type. The application of sodium valproate anti-seizure medication could effectively control the seizures of the child, and by giving rehabilitation function training, the child′s language and gross motor function was improved. Conclusions:The Poirier-Bienvenu neurodevelopmental syndrome is a rare autosomal dominant disorder caused by variants in the CSNK2B gene. The clinical manifestations are infancy-onset seizures, intellectual development disorders, language and motor development disorders, etc, and the video electroencephalogram and skull magnetic resonance are mostly normal. The CSNK2B gene shear variant is the genetic etiology of the proband.
