Objective:To explore relevant factors to accurately diagnose BPPV in vertigo children. Methods:A retrospective study was conducted on the proportion of BPPV in children（<18 years） with vertigo who visited the Hearing and Vertigo Diagnosis and Treatment Center of Tianjin Medical University General Hospital from September 2017 to August 2023. The clinical characteristics of BPPV children, including general demographics, medical history, first visit department, comorbidities, canal involvement, response to treatment, and incidence of recurrence, were analyzed. Data analysis was conducted using SPSS 25.0 software. Results:BPPV was diagnosed in 22.8% of patients seen for vertigo during the study period. There are differences in the proportion of BPPV diagnosis among children with dizziness in different age groups（P<0.05）, and the diagnosis of BPPV in the 7-12-year-old group has a longer disease course than in the 13-17-year-old group（P<0.05）. 72.3%（47/65） of patients or their families were able to provide a typical history of positional vertigo. 49.2%（32/65） of BPPV patients had comorbidities, and there were differences in the proportion of comorbidities among different age groups of BPPV patients（P<0.05）. With the progress of study, the proportion of BPPV in children with vertigo has shown an upward trend, and the proportion of children with otolaryngology as the first diagnosis department has also increased（P<0.05）. The proportion of horizontal semicircular canals in children with BPPV has increased. All BPPV patients underwent canalith repositioning maneuvers, with good treatment outcomes and a recurrence rate of 12.3%（8/65）. The recurrence rate in the group of BPPV patients with comorbidities was 21.9%, which was higher than that in the group without comorbidities（P<0.05）. Conclusion:Childhood BPPV has clinical characteristics such as unclear medical history, high proportion of comorbidities, easy recurrence in BPPV children with comorbidities and high proportion of horizontal semicircular canal involvement. For children diagnosed with other vertigo diseases, do not ignore the BPPV diagnostic test. It is recommended to perform routine position tests on children with vertigo if conditions permit to reduce missed diagnosis of BPPV in children.

ObjectiveThe significance of adverse childhood experiences (ACEs) among men who have sex with men (MSM) should not be overlooked. This study aims to assess the reliability and validity of the Chinese version of the Adverse Childhood Experiences-International Questionnaire (ACE-IQ) among the MSM population in China to evaluate its applicability in this group. MethodsA cross-sectional survey was conducted in three Chinese cities(Shanghai, Shenyang and Kunming) using snowball sampling, with a total of 1 130 MSM participants included. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to assess the structural validity of the scale. Internal consistency reliability was evaluated using Cronbach’s α coefficient, and split-half reliability was assessed with the Spearman-Brown coefficient. ResultsAccording to the EFA results, after removing item ACE10 (“parental death”), the 23-item ACE-IQ demonstrated a six-factor structure, including victimization or witnessing emotional/physical abuse, sexual abuse, physical neglect, family dysfunction, emotional neglect, and peer violence. CFA results indicated a good model fit for the six-factor model, supporting the EFA findings. The scale demonstrated good reliability, with a Cronbach's α coefficient of 0.852 and a Spearman-Brown coefficient of 0.899, indicating high internal consistency and split-half reliability within the studied population. ConclusionThe Chinese version of the ACE-IQ demonstrates satisfactory reliability and validity among MSM population, supporting its suitability for assessing ACEs in this group. The findings provide an empirical basis for subsequent mental health interventions.

Objective:To observe the clinical effect of adjustable silicone strap suspension in the treatment of myasthenia gravis ptosis.Methods:From January 2019 to January 2020, 60 patients with myasthenia gravis ptosis (35 males, 25 females, age distribution from 25 to 58 years, with average of 35.63 years) were collected from the Department of Ophthalmoplasty of Aier Eye Hospital affiliated to Wuhan University. They were divided into control group and observation group, with 30 cases in each group. The observation group was treated with adjustable silicone band suspension, and the correction effect, satisfaction, recovery status, ocular surface function index, recurrence rate and complications of the two groups were compared.Results:The excellent rate of operation in the observation group was 93.33% (28/30), which was significantly higher than 63.33% (19/30) in the control group (χ 2=6.29, P<0.05), and the satisfaction of patients in the observation group was 100% (30/30), which was significantly higher than 76.67% (23/30) in the control group (χ 2=5.82, P<0.05). The preoperative corneal curvature and fluorescein staining in the observation group and the control group were significantly lower than those in the postoperative state ( t=6.17, 21.48, P<0.05). The corneal curvature and fluorescein staining score of the observation group were significantly higher than those of the control group at 3 months after surgery ( t=3.00, 9.06, P<0.05). There was no significant difference between the two groups in the incidence of complications such as eyelid imclosure, upper eyelid inversion and unnatural upper eyelid curvature (χ 2=0.19, P>0.05). Follow up at 3 months after surgery, the recurrence rate in the observation group was lower than that in the control group (χ 2=4.63, P<0.05). Conclusions:Surgery is an option for patients with myasthenia gravis ptosis who are not responding well to medical treatment and whose condition is stable. Adjustable silicone strap suspension for the treatment of myasthenia gravis ptosis can significantly improve the surgical success rate and patient satisfaction, with low postoperative complication rate and recurrence rate, which is suitable for clinical application.

ObjectiveTo investigate the condom use of men who have sex with men （MSM） in Shanghai， the information motivation behavioral skills model （IMB） theory was used to introduce psychosocial factors and study the relevant factors of consistent condom use （CCU） in this population. MethodsA cross-sectional study of 547 MSM in four districts of Shanghai was conducted by snowball sampling. The structural equation model based on psychosocial optimization was constructed and validated using the data collected by structured questionnaires. ResultsAmong the 547 respondents， the proportion of CCU in the past six months was 45.5%. Comparing the fitness of the initial model with that of the adjusted model， we found that the fitness of the adjusted model was good. ConclusionThe proportion of CCU among MSM in Shanghai is relatively low； In addition， information and motivation do not directly affect the CCU of this population； Only behavioral skills have a direct effect on CCU. Finally， social psychological measures should be emphasized for this population， and comprehensive and multi-level strategies should be formulated to control the spread of HIV in this population.

Objective:To observe the changes of corneal curvature and ocular surface after congenital ptosis.Methods:A total of 188 patients with congenital blepharoptosis were treated with frontal muscle flap suspension, levator eyelid muscle shortening and fixation, and levator aponeurosis according to different conditions. The postoperative correction effect, corneal curvature, and ocular surface changes were observed.Results:There was no significant difference in the good correction rate among the three methods ( P>0.05). The corneal curvature at 3 months after operation was lower than that before operation and 7 days after operation ( P<0.05). The fluorescein staining score at 7 days after operation was higher than that before operation and 3 months after operation ( F=2 910.05, P<0.05). The tear film rupture time at 7 days after operation was significantly shorter than that before operation and 3 months after operation ( F=758.12, P<0.05). There was no significant difference in tear secretion test before operation, 7 days after operation and 3 months after operation ( P>0.05). The conjunctival congestion score at 3 months after operation was lower than that at 7 days after operation, and the incidence of meibomian gland dysfunction and abnormal eyelash angle at 3 months after operation was lower than that at 7 days after operation ( t=113.56, χ 2=11.02, 11.46, P<0.05). 3 months after operation, the average diopters of 3 mm and 5 mm were higher than those before operation ( t=12.35, 15.19, P<0.05). Conclusions:Frontal muscle suspension, levator eyelid muscle shortening and fixation, and levator aponeurosis are effective in treating congenital blepharoptosis, and can effectively improve the ocular surface and corneal curvature. Clinically, the appropriate one can be selected according to the condition of the child correction method.

OBJECTIVE: To explore the genetic basis for a patient with intellectual disability. METHODS: Whole exome sequencing and Sanger sequencing were carried out for the patient. The result was verified in her family. RESULTS: DNA sequencing revealed that the patient has carried a heterozygous nonsense c.40C>T (p.Arg14X) variant of the TRIP12 gene, which was de novo in origin. The variant was unrecorded in the Human Gene Mutation Database. Based on the American College of Medical Genetics and Genomics standards and guidelines, the variant was predicted to be pathogenic (PVS1+ PS2+ PP3). CONCLUSION The patient was diagnosed with autosomal dominant intellectual disability due to heterozygous c.40C>T variant of the TRIP12 gene.

The mutation of lysosomal trafficking regulator (LYST) gene and the clinical data of an adult patient who showed an abnormal gait with Chediak-Higashi syndrome were analyzed retrospectively. The whole exon sequencing was applied, and Sanger sequencing was used to verify the results. All members of the family were genetically verified for the same mutation site. The sequencing revealed the presence of c.421C>T(p.Arg141 *) mutation in LYST gene in the proband, which was inherited from his parents. The mutation was found in the homozygous state for the proband, both his parents being heterozygous for the same mutation. This mutation type was not reported in the human gene mutation database. According to the American Society of Medical Genetics and Genomic Society′s guide to the interpretation of genetic variation, the mutation of c.421C>T was identified to be pathogenic.

Objective:To analyze the registration status of acute pancreatitis-related clinical studies registered on the Chinese Clinical Trial Registry (ChiCTR) and USA ClinicalTrials.gov database.Methods:The ChiCTR and ClinicalTrials.gov database were searched to collect, sort and analyze the clinical studies related to acute pancreatitis registered from the establishment of the database to December 31, 2020. The clinical trials were manually grouped, and the features of clinical researches were compared based on different registered data (2007-2014 vs 2015-2020) and different financial sources (self-support, enterprise support or public support). Results:A total of 157 registered clinical studies related to acute pancreatitis have been included (ChiCTR n=99; ClinicalTrial.gov n=58). The top three areas with the greatest number of registered clinical studies were Sichuan (28.0%), Shanghai (14.6%) and Jiangsu (12.1%), totally accounting for 54.7%. There were 91 interventional studies, 41 observational studies and 25 other type studies. Masking was performed in 34 studies (21.6%). Randomized parallel controlling was performed in 84 studies (53.5%). 30 trials (19.1%) were at Ⅳ phase, and 7 trials (4.4%) were at Ⅱ or Ⅲ phase. 2007-2014 group tended to use randomized parallel controlled design (68.3% vs 45.4%, P=0.005) and randomization grouping (76.7% vs 47.4%, P=0.001). 2015-2020 group tended to use relatively large sample (72.6% vs 47.4%, P=0.002)and data management committee (53.6% vs 25.0%, P=0.001). The differences between the two groups were statistically significant. Of 92 trials from ChiCTR database, 48 were self-supported, 5 was supported by enterprise, and 38 was supported by the public. The percentage of self-support and public support was 86.9%. Conclusions:The number of acute pancreatitis-related clinical studies registered on ChiCTR was generally on the increase. Most registered studies were funded by public finances or by the researchers' institutions self. There was a lack of phaseⅡ or phase Ⅲ.

Objective? To investigate and analyze the relationship between relocation stress,family function and coping strategy in parents of children transferred from Intensive Care Uni(t ICU). Methods? Using the method of cross-sectional study, the parents of children transferred from ICU to general ward in Children's Hospital Affiliated to Zhengzhou University from October 2018 to March 2019 were selected as the subjects of study by convenience sampling. General Information Questionnaire, Family Relocation Stress Scale (FRSS), Feetham Family Functioning Survey(FFFS),and the Coping Health Inventory for Parents(CHIP) were used to evaluate the relocation stress level and analyze the relationship between scores of FRSS, FFFS, and CHIP. A total of 200 questionnaires were distributed and 179 valid ones were retrieved, yielding an effective recovery rate of 89.5%. Results? The total score of FRSS of the 179 ICU-transferred children's parents was (34.52±8.46), which was in a high level of stress; the total average score of FFFS was (1.27±1.14); the total score of "coping style use frequency" was (144.57±13.57) in CHIP, and the total score of "coping style effect"was (78.20±14.83); correlation analysis showed that each dimension and total score of FFFS was negatively correlated with the level of relocation stress of parents (P＜0.05), and positively correlated with the "frequency and role of coping styles" (P＜0.05). Conclusions? The relocation stress of ICU-transferred children's parents is serious. Family function and coping style are closely related to the level of relocation stress. Medical staff should pay attention to the adaptation of families in the process of transfer, encourage parents to adopt more positive ways to cope with diseases and improve the overall health of children and families.

PURPOSE: c-Met and its ligand, hepatocyte growth factor (HGF), play a critical role in oncogenesis and metastatic progression. The aim of this study was to identify inhibited enzymogram and to test the antitumor activity of SIM-89 (a c-Met receptor tyrosine kinase inhibitor) in non-small cell lung cancer. MATERIALS AND METHODS: Z′-LYTE kinase assay was employed to screen the kinase enzymogram, and mechanism of action (MOA) analysis was used to identify the inhibited kinases. Cell proliferation was then analyzed by CCK8 assay, and cell migration was determined by transwell assay. The gene expression and the phosphorylation of c-Met were examined by realtime-PCR and western blotting, respectively. Finally, the secretion of HGF was detected by ELISA assay. RESULTS: c-Met, activated protein kinase (AMPK), and tyrosine kinase A (TRKA) were inhibited by SIM-89 with the IC₅₀ values of 297 nmol/L, 1.31 µmol/L, and 150.2 nmol/L, respectively. SIM-89 exerted adenosine triphosphate (ATP) competitive inhibition on c-Met. Moreover, the expressions of STAT1, JAK1, and c-Met in H460 cells were decreased by SIM-89 treatment, and c-Met phosphorylation was suppressed in A549, H441, H1299, and B16F10 cells by the treatment. In addition, SIM-89 treatment significantly decreased the level of HGF, which accounted for the activation of c-Met receptor tyrosine kinase. Finally, we showed cell proliferation inhibition and cell migration suppression in H460 and H1299 cells after SIM-89 treatment. CONCLUSION: In conclusion, SIM-89 inhibits tumor cell proliferation, migration and HGF autocrine, suggesting it's potential antitumor activity.
