Objective:To analyze the clinical characteristics of children with head and neck rhabdomyosarcoma (RMS) and to summarize the mid-long term efficacy of Beijing Children′s Hospital Rhabdomyosarcoma 2006 (BCH-RMS-2006) regimen and China Children′s Cancer Group Rhabdomyosarcoma 2016 (CCCG-RMS-2016) regimen.Methods:A retrospective cohort study. Clinical data of 137 children with newly diagnosed head and neck RMS at Beijing Children′s Hospital, Capital Medical University from March 2013 to December 2021 were collected. Clinical characteristic of patients at disease onset and the therapeutic effects of patients treated with the BCH-RMS-2006 and CCCG-RMS-2016 regimens were compared. The treatments and outcomes of patients with recurrence were also summarized. Survival analysis was performed by Kaplan-Meier method, and Log-Rank test was used for comparison of survival rates between groups.Results:Among 137 patients, there were 80 males (58.4%) and 57 females (41.6%), the age of disease onset was 59 (34, 97) months. The primary site in the orbital, non-orbital non-parameningeal, and parameningeal area were 10 (7.3%), 47 (34.3%), and 80 (58.4%), respectively. Of all patients, 32 cases (23.4%) were treated with the BCH-RMS-2006 regimen and 105 (76.6%) cases were treated with the CCCG-RMS-2016 regimen. The follow-up time for the whole patients was 46 (20, 72) months, and the 5-year progression free survival (PFS) and overall survival (OS) rates for the whole children were (60.4±4.4)% and (69.3±4.0)%, respectively. The 5-year OS rate was higher in the CCCG-RMS-2016 group than in BCH-RMS-2006 group ((73.0±4.5)% vs. (56.6±4.4)%, χ2=4.57, P=0.029). For the parameningeal group, the 5-year OS rate was higher in the CCCG-RMS-2016 group (61 cases) than in BCH-RMS-2006 group (19 cases) ((57.3±7.6)% vs. (32.7±11.8)%, χ2=4.64, P=0.031). For the group with meningeal invasion risk factors, the 5-year OS rate was higher in the CCCG-RMS-2016 group (54 cases) than in BCH-RMS-2006 group (15 cases) ((57.7±7.7)% vs. (30.0±12.3)%, χ2=4.76, P=0.029). Among the 10 cases of orbital RMS, there was no recurrence. In the non-orbital non-parameningeal RMS group (47 cases), there were 13 (27.6%) recurrences, after re-treatment, 7 cases survived. In the parameningeal RMS group (80 cases), there were 40 (50.0%) recurrences, with only 7 cases surviving after re-treatment. Conclusions:The overall prognosis for patients with orbital and non-orbital non-parameningeal RMS is good. However, children with parameningeal RMS have a high recurrence rate, and the effectiveness of re-treatment after recurrence is poor. Compared with the BCH-RMS-2006 regimen, the CCCG-RMS-2016 regimen can improve the treatment efficacy of RMS in the meningeal region.

Objective To noninvasively predict isocitrate dehydrogenase(IDH)status of glioma via combining imaging and clini-cal features before surgery,so as to provide basis for individualized clinical treatment decision.Methods A total of 47 patients with glioma confirmed by pathological and molecular genetic tests were included,including 20 with IDH mutant type and 27 with IDH wild type.After diffusion tensor imaging(DTI)scanning,fractional anisotropy(FA)and mean diffusivity(MD)values of tumor paren-chyma were calculated.Combining DTI parameters with MRI morphological features of tumor,blood neutrophil/lymphocyte ratio(NLR)and patient's age,binary logistic regression model was established to effectively predict IDH status of glioma patients before surgery.Results There were significant differences in FAmean/FANAWM,MDmin,NLR,tumor location and age between IDH mutant type and IDH wild type groups(P<0.05).The binary logistic regression model concluding,FAmean/FANAWM,MDmin,cystic degeneration,NLR and age,predicted IDH status of glioma with area under the curve(AUC)of 0.961 and 95%confidence interval(CI)of 0.914-1.00.Conclusion The regression model established via combining DTI,MRI morphological features and blood NLR has great performance in classifying IDH status of glioma,and can help predict IDH status noninvasively before surgery,so as to assist clinical individualized treatment.

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective:To evaluate the efficacy and safety of Xiao′er Huangjin Zhike Granules in the treatment of cough caused by acute bronchitis in children, which is defined in TCM terms as a syndrome of phlegm-heat obstructing the lung.Methods:This was a block-randomized, double-blind, placebo-controlled, multicenter clinical trial.From January 2022 to September 2023, 359 children aged 3 to 7 years old diagnosed as acute bronchitis (lung-obstructing phlegm-heat syndrome) were enrolled from 21 participating hospitals and randomly assigned to the experimental group and placebo group in a 3︰1 ratio, and respectively treated with Xiao′er Huangjin Zhike Granules and its matching placebo.Cough resolution/general resolution rate after 7 days of treatment was used as the primary efficacy outcome for both groups.Results:(1)On the seventh day of treatment, the rate of cough disappearance/basically disappearance in the experimental group and placebo group were 73.95% and 57.61% retrospectively, which had statistically significance ( P=0.001).(2)After 7 days of treatment, the median duration of cough disappearance/basic disappearance were 5 days and 6 days in the two groups , with a statistically significant difference ( P=0.006).The area under the curve of cough symptom severity time was 7.20 ± 3.79 in the experimental group and 8.20±4.42 in the placebo group.The difference between the two groups was statistically significant ( P=0.039).(3) After 7 days of treatment, the difference between TCM syndrome score and baseline was -16.0 (-20.0, -15.0) points in the experimental group and -15.0 (-18.0, -12.0) points in the placebo group, with significant difference between the two groups ( P=0.004).In the experimental group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 49.04%, 28.35%, 16.48% and 6.13% severally; and in the placebo group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 38.04%, 26.09%, 29.35%, and 6.52% separately, which had statistically significant ( P=0.014).(4) There was no significant difference in the incidence of adverse events or adverse reactions during the trial between both groups.Moreover, while adverse reactions in the form of vomiting and diarrhea were occasionally reported, no serious drug-related adverse event or adverse reaction was reported.(5)The tested drug provided good treatment compliance, showing no statistically significant difference from the placebo in terms of compliance rate. Conclusions:Based on the above findings, it can be concluded that Xiao′er Huangjin Zhike Granules provides good safety, efficacy, and treatment compliance in the treatment of cough caused by acute bronchitis, and lung-obstructing phlegm-heat syndrome, in children.

Objective:To explore the clinical and molecular basis for a Chinese pedigree affected with Complete androgen insensitivity syndrome (CAIS).Methods:A CAIS pedigree presented at Tianjin Medical University General Hospital between 2019 and 2021 was selected as the study subject. Clinical data of the proband was collected, along with peripheral blood samples from the proband and her family members. Chromosomal karyotyping, sex-determining region of the Y chromosome ( SRY) testing, and next-generation sequencing (NGS) were carried out for the proband, and candidate variant was verified by Sanger sequencing of her family members. Prenatal diagnosis was provided for the sister of the proband. This study was approved by Medical Ethics Committee of the Tianjin Medical University General Hospital (Ethics No. IRB2023-WZ-070). Results:The 18-year-old proband, who has a social gender of female, underwent laparoscopic examination, which showed no presence of uterus and ovaries. The karyotype of peripheral blood sample was 46, XY, with SRY gene detected. NGS indicated that the proband has harbored a heterozygous c. 1988C>G (p.Ser663Ter) variant of the AR gene. Sanger sequencing confirmed that her mother and sister had both harbored the same variant, whilst her father and younger sister were of the wild-type. Prenatal diagnosis revealed that her sister′s first fetus had harbored carried the same variant, which had led to termination of pregnancy. Her second fetus did not carry the variant, and a healthy boy was born. Based on guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as likely pathogenic (PM2_Supporting+ PM4+ PP3_Moderate+ PP4). Conclusion:The c. 1988C>G (p.Ser663Ter) variant of the AR gene probably underlay the CAIS in the proband. The accurate diagnosis of sex development disorders will rely on the physicians′ thorough understanding of the clinical symptoms and pathogenic genes. Genetic testing and counseling can enable precise diagnosis, prenatal diagnosis, and guidance for reproduction

ObjectiveTo observe the architectural parameter changes of the muscles around the knee in middle-aged and elderly women with early knee osteoarthritis (KOA) by musculoskeletal ultrasound, and to clarify the indicators of muscles that affect early KOA. MethodsFrom January to August, 2022, 20 healthy middle-aged and elderly healthy women (controls) and 20 middle-aged and elderly women with unilateral early KOA (KOA group) were recruited through Beijing Bo'ai Hospital, to measure muscle thickness of the popliteus muscle, the muscle thickness and the pennation angle of the quadriceps, as rectus femoris, vastus intermedius, vastus lateralis, vastus medialis longus and vastus medialis oblique. ResultsCompared with the healthy limb of KOA group, and the controls, the muscle thickness of vastus medialis longus, vastus medialis oblique and popliteus muscle of the affected limb of KOA group became thinner (t > 2.133, P < 0.05); the proportion of thickness of vastus medialis oblique to thickness of vastus lateralis became smaller (t > 3.660, P < 0.05). The pennation angle was smaller in the affected limb of KOA group than in the matched dominant side of the controls (t = 3.101, P < 0.05). Logistic regression analysis showed that the muscle thickness of vastus medialis oblique (OR = 0.235, 95%CI 0.068 to 0.805, P = 0.021) and popliteus muscle (OR = 0.387, 95%CI 0.152 to 0.980, P = 0.045) were related to the onset of early KOA. ConclusionThe thickness of vastus medialis longus, vastus medialis oblique and popliteus muscle decrease, and the balance of the strength of vastus medialis oblique and vastus lateralis weakens in the affected limbs of the middle-aged and elderly women with early KOA. The thickness of vastus medialis oblique and popliteus muscle are protective factors for onset of KOA.

ObjectiveTo analyze the effect of standardized training on post competency of rehabilitation therapists, based on World Health Organization rehabilitation competency framework (RCF), and combined with the characteristics of rehabilitation and the requirements of standardized training in China. MethodsFrom 2018 to 2022, a total of 30 rehabilitation therapists who participated in the standardized training were selected. Before and after the standardized training, the closed-book theoretical assessment and Mini-clinical Evaluation Exercise (Mini-CEX) assessment were carried out, and a 360-Degree Evaluation scale was distributed to their teachers, peers and patients. Through multi-dimensional post competency analysis, the data obtained from the scales were combined with the five dimensions of basic theoretical knowledge, clinical practice ability, medical humanities literacy, scientific research and teaching ability, and organizational management ability to analyze the effect of standardized training on post competency of rehabilitation therapists. ResultsAfter training, the therapists improved in theory and case analysis (Z > 2.716, P < 0.05). They also improved in medical interview skills, physical examination, humane care/professionalism, clinical judgment ability and overall clinical level (Z > 2.162, P < 0.05) according to Mini-CEX. The medical ethics, daily work, management ability, social ability, interpersonal communication ability, basic professional ability and operation ability improved (Z > 1.978, P < 0.05) according to the 360-Degree Evaluation scale. The effect of standardized training was significant in basic theoretical knowledge, clinical practice ability and medical humanities literacy by the post competency analysis model. ConclusionThe effect of standardized training of rehabilitation therapists is significant, and the therapists can be competent for daily work in diagnosis and treatment after training.

Purpose: This study aimed to investigate reproductive concerns among breast cancer patients of reproductive age, analyze the influencing factors, explore the relationship between coping styles, fear of progression (FOP), and reproductive concerns, and identify the multiple effects of coping styles on the relationship between FOP and reproductive concerns among Chinese breast cancer patients. Methods: A cross-sectional, descriptive study was conducted among breast cancer patients in four tertiary grade A hospitals in Fujian, China, from January 2022 to September 2022. A total of 210 patients were recruited to complete paper-based questionnaires, which included the general data questionnaires, the Reproductive Concerns After Cancer Scale (RCACS), the Fear of Progression Questionnaire-Short Form (FOP-Q-SF), and the Medical Coping Modes Questionnaire (MCMQ). Structural equation models were utilized to evaluate the multiple effects of coping styles on FOP and reproductive concerns. Results: Reproductive concerns in breast cancer patients had a mean score of 53.02 (SD, 10.69), out of a total score of 90, and coping styles for cancer (confrontation, avoidance) were closely associated with FOP and reproductive concerns. FOP showed a significant positive correlation with reproductive concerns (r = .52, p < .01). At the same time, confrontation was significantly negatively correlated with both FOP (r = −.28, p < .01) and reproductive concerns (r = −.39, p < .01). Avoidance was positively correlated to both FOP (r = .25, p < .01) and reproductive concerns (r = .34, p < .01). The impact of FOP on reproductive concerns is partially mediated by confrontation and avoidance, with effect sizes of .07 and .04, respectively. These mediating factors account for 22.0% of the total effect. Conclusions The FOP directly impacted reproductive concerns, while coping styles could partially mediate the association between FOP and reproductive concerns. This study illustrates the role of confrontation and avoidance in alleviating reproductive concerns, suggesting that it is necessary to focus on the changes in reproductive concerns among reproductive-age breast cancer patients. Healthcare professionals can improve disease awareness and reduce patients' FOP, thereby promoting positive psychological and coping behaviors and ultimately alleviating reproductive concerns.

ObjectiveTo explore the mechanism of Chenpi Huoxiangtang against diarrhea based on network pharmacology and experimental verification. MethodThe active components and targets of Chenpi Huoxiangtang were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and targets related to diarrhea from GeneCards and Online Mendelian Inheritance in Man （OMIM）. Thereby， the common targets were screened out. The component-target-disease network and protein-protein interaction （PPI） network were constructed with Cytoscape 3.7.1 and STRING. Bioconductor and R language were employed for gene ontology （GO） term enrichment and Kyoto encyclopedia of genes and genomes （KEGG） pathway enrichment of core targets， and AutoDockTools 1.5.6 and AutoDockVina 1.1.2 for molecular docking. Finally， animal experiment was carried out for verification. ResultA total of 51 active components 226 targets of Chenpi Huoxiangtang and 37 common targets of the medicine and the disease were screened out. The core targets were involved in 1 249 GO terms （P<0.05） and 110 KEGG pathways （P<0.05）， mainly the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， hypoxia inducible factor （HIF）-1， and mitogen-activated protein kinase （MAPK） pathways. Molecular docking suggested that hesperidin and Akt1 showed the highest binding affinity. Animal experiment demonstrated that Chenpi Huoxiangtang significantly alleviated the diarrhea symptoms. The diarrhea index on the first day of administration decreased to 0.92， which was statistically different from that （1.24） of the model group （P<0.05）. The intestinal ink propulsion rate was 70.36%， higher than that （58.20%） in the model group （P<0.01）. Moreover， intestinal peristalsis was improved by the decoction. Enzyme-linked immunosorbent assay （ELISA） indicated the decrease in the levels of interleukin-6 （IL-6） and interleukin-1β （IL-1β） （P<0.05） and increase in the levels of Akt1， epidermal growth factor （EGF）， and epidermal growth factor receptor （EGFR） （P<0.05）. ConclusionThe active components of Chenpi Huoxiangtang mainly regulate PI3K/Akt， MAPK， and other signaling pathways through Akt1， IL-6， IL-1β， EGF， EGFR， and other core targets， thereby relieving diarrhea. This study is expected to lay a basis for the research on the pharmacological mechanism of Citri Reticulatae Pericarpium-Pogostemonis Herba combination and the scientific connotation of their compatibility.

Objective To retrospectively study the etiology of patients with community-acquired pneumonia-like syndrome in Zhangjiakou area in the past 3 years, and to provide guidance for clinical rapid diagnosis and empirical treatment. Methods A total of 471 patients with community-acquired pneumonia-like syndrome were initially diagnosed in the outpatient or inpatient hospitals in Zhangjiakou area from August 2015 to August 2018. According to the age of the cases, they were divided into the youth group (age≤29 years old, n=89), the junior middle-aged group (30≤age≤39, n=124), the middle-aged group (40≤age≤49, n=177) , and the elderly group (age≥50, n=81). The clinical records of each group of patients were collected to explore the clinical features and etiology of community-acquired pneumonia-like syndrome in different age groups. Results (1)The comparison of the duration of disease in each group showed that the duration of disease in the youth group was significantly lower than the average, while the duration of the elderly group was significantly higher than the average. There was no significant difference in the duration of the disease between the junior middle-aged and middle-aged groups; (2)Seasonal statistics of community-acquired pneumonia-like syndrome found that the overall incidence rate in autumn (48.20%) was higher than that in spring (13.06%), summer (16.77%), and winter (21.97%). The incidence in the elderly group mainly occurred in autumn and winter, which was significantly different from the other three groups; (3)The comparison of the CURB-65 scores revealed that the youth and the junior middle-aged groups were mainly at low-risk (57.30%, 65.32%), the middle-aged group was at low-risk and intermediate-risk (40.68%, 50.28%), and the elderly group was mainly at intermediate-risk and high-risk (29.01%, 33.33%). All the differences were statistically significant (P<0.05). Conclusion The community-acquired pneumonia-like syndrome in Zhangjiakou area was predominantly high in autumn, and was common in the elderly population. The disease was more serious with a longer course in the elderly group than other populations, which should be paid attention to in clinical practice.
