Objective:To explore the effect of APP based case management model in female patients with stress urinary incontinence (SUI) .Methods:From March 2022 to August 2023, convenience sampling was used to select 87 female SUI patients who visited the Pelvic Floor Clinic of the First Bethune Hospital of Jilin University as participants. Patients from March to November 2022 were selected as control group ( n=45) based on their treatment time, and received routine biofeedback electrical stimulation therapy combined with pelvic floor muscle exercise. Patients from December 2022 to August 2023 were selected as observation group ( n=42) and given an APP based case management model on the basis of control group. Before treatment, after treatment, and three months after treatment, the 1-hour pad test, Glazer assessment, and International Consultation Incontinence Questionnaire Short-Form (ICIQ-SF) were used for evaluation. Results:Three cases in control group withdrew midway, while observation group completed interventions and follow-up. The urine leakage of both groups of patients decreased after treatment and three months after treatment compared to before treatment, and the symptom relief in observation group was better than that in control group, with statistical differences ( P<0.05). Three months after treatment, observation group showed statistically better peak fast muscle contractions, mean value of slow muscle contractions, and mean value of endurance contractions in Glazer assessment compared to control group ( P<0.05). The ICIQ-SF scores of observation group patients were statistically lower than those of control group after treatment and three months after treatment ( P<0.05) . Conclusions:Combining conventional pelvic floor rehabilitation with an APP based case management model can increase process management and personalized guidance for female SUI patients, ensure the continuity of rehabilitation exercise, alleviate urinary leakage symptoms, improve treatment effectiveness, and promote patient recovery.

Objective:To summarize the clinical characteristics, causes of misdiagnosis and preventive measures of infectious mononucleosis (IM) in children, and to improve the ability of clinicians in early diagnosis of IM in children.Methods:The clinical data of 468 children with IM in Xi′an Children′s Hospital from January 2018 to December 2021 were retrospectively analyzed, including general situation, disease onset, diagnosis and misdiagnosis.Results:Among the 468 children, 33 cases were clinically diagnosed and 435 cases were a definitely diagnosed; 281 males (60.04%) and 187 females (39.96%); the incidence rate was highest in preschool children (43.80%, 205/468) and in autumn (33.12%, 155/468). The first symptoms were fever (52.99%, 248/468), eyelid edema (15.38%,72/468) and neck mass (14.96%, 70/468). The fever rate was 90.38% (423/468), and the median time of first fever appearance was on the first (first, second) day of disease course, and the median duration of fever was 6 (4, 8) d. The median time of first visit was on the third (first, fifth) day of disease course, and the time of diagnosis was on the seventh (fifth, ninth) day of disease course. Blood routine examination showed that the proportion of white blood cell count increased was 51.92% (243/468), the proportion of lymphocytes increased was 61.75% (289/468), and the proportion of abnormal lymphocytes increased (≥10%) in peripheral blood was 58.97% (276/468). The lymphocyte subsets of 364 children were detected, the rate of helper T lymphocytes (Th cells) decreased was 80.22% (292/364), the rate of suppressor T lymphocytes (Ts cells) increased was 99.45% (362/364), the value and decreased rate of Th cells/Ts cells were 0.24 (0.16, 0.40) and 100.00% (364/364), rate of B lymphocytes decreased was 93.96% (342/364), rates of natural killer cells decreased and increased were 35.16% (128/364) and 0.55% (2/364). The misdiagnosis rate was 55.13% (258/468), and the misdiagnosis time was on the fifth (fourth, seventh) day of disease course. Among the 258 misdiagnosed children, 105 cases (40.70%) were misdiagnosed as upper respiratory tract infection, 65 cases (25.19%) as acute suppurative tonsillitis, 27 cases (10.47%) as acute cervical lymphadenitis or neck mass.Conclusions:Due to the complex and diverse clinical manifestations of IM in children, it is easy to be misdiagnosed in the early stage of the disease. So, it is necessary for clinicians to master the clinical characteristics of IM in children, constantly improve the level of diagnosis and treatment, and reduce the misdiagnosis rate.

Objective To analyze TCM master Yan Zhenghua's medication rules of ascending,descending,floating and sinking properties for the treatment of respiratory diseases,inherit his valuable academic experience.Methods Using four books edited by Professor Yan Zhenghua's disciples as the main source,Professor Yan Zhenghua's prescriptions for clinical treatment of respiratory diseases were systematically collected and analyzed.Statistical analysis was conducted on the patients'gender and age,differentiation of diseases and syndrome types of the prescriptions,as well as the properties of ascending,descending,floating and sinking,dosage,and commonly used pairs of Chinese materia medica.Results Totally 208 prescriptions were included in this study,involving 178 kinds of Chinese materia medica and 64 kinds of monarch drug,most of them were descending and sinking drug,and the whole prescription was mainly descending and sinking.On average,each prescription used 13.2 kinds of Chinese materia medica,and most dosage points were within the range of conventional dosage.Among later adding medicines,Houttuyniae Herba had the highest frequency of use.The medicinal pairs of Asteris Radix et Rhizoma-Cynanchi Stauntonii Rhizoma et Radix,Cynanchi Stauntonii Rhizoma et Radix-Stemonae Radix and Asteris Radix et Rhizoma-Stemonae Radix were often used.Armeniacae Semen Amarum,Fritillariae Thunbergii Bulbus,and Asteris Radix et Rhizoma were commonly used in those descending and sinking prescriptions.Conclusion In the treatment of respiratory diseases,Professor Yan Zhenghua prefers to use descending and sinking drugs with ascending and floating drugs and dual trend drugs to regulate qi activity,and has the characteristics of Menghe medical school,which is"mild and flexible medication".

Objective To explore the pathogenesis of Russell-Silver syndrome (RSS). Methods Two milliliter peripheral blood samples were collected from 6 male patients aged 6 to 8 years with suspected RSS phenotype, the parents of 2 patients and 5 healthy boys. Mononuclear cells were isolated and genomic DNA was extracted. The methylation level of the H19 imprinting control region(ICR)1 on chromosome 11p15.5 was detected by pyrosequencing.The methylation status and the copy number variation in the corresponding region of one RSS patient with positive results by pyrosequencing were analysed by methylation-specific multiplex-ligation-dependent probe amplification assay (MS-MLPA). Results Pyrosequencing analysis revealed that the methylation rates on the 6 CpG targeting sites in H19 differentially methylated region(DMR)in the 6 RSS patients were about 11%~29%, which were significantly lower than those in their parents and normal controls (44%~59%). The MS-MLPA results of one patient with positive pyrosequencing showed that the methylation rates of 4 sites in H19-DMR were about 10%,which was obviously lower than the normal level.The methylation rates of the 4 sites in KCNQ1OT1 gene were about 50%, which was in the normal range. The copy number variations from all samples detected were in the normal range. Conclusion There is methylation aberration of H19-DMR in ICR1 in children with RSS.
