Here, we report a previously unrecognized syndromic neurodevelopmental disorder associated with biallelic loss-of-function variants in the RBM42 gene. The patient is a 2-year-old female with severe central nervous system (CNS) abnormalities, hypotonia, hearing loss, congenital heart defects, and dysmorphic facial features. Familial whole-exome sequencing (WES) reveals that the patient has two compound heterozygous variants, c.304C>T (p.R102*) and c.1312G>A (p.A438T), in the RBM42 gene which encodes an integral component of splicing complex in the RNA-binding motif protein family. The p.A438T variant is in the RRM domain which impairs RBM42 protein stability in vivo. Additionally, p.A438T disrupts the interaction of RBM42 with hnRNP K, which is the causative gene for Au-Kline syndrome with overlapping disease characteristics seen in the index patient. The human R102* or A438T mutant protein failed to fully rescue the growth defects of RBM42 ortholog knockout ΔFgRbp1 in Fusarium while it was rescued by the wild-type (WT) human RBM42. A mouse model carrying Rbm42 compound heterozygous variants, c.280C>T (p.Q94*) and c.1306_1308delinsACA (p.A436T), demonstrated gross fetal developmental defects and most of the double mutant animals died by E13.5. RNA-seq data confirmed that Rbm42 was involved in neurological and myocardial functions with an essential role in alternative splicing (AS). Overall, we present clinical, genetic, and functional data to demonstrate that defects in RBM42 constitute the underlying etiology of a new neurodevelopmental disease which links the dysregulation of global AS to abnormal embryonic development.

AIM: To evaluate the changes in corneal epithelial thickness(CET)and corneal optical density(CD)after smart pulse technology(SPT)-assisted transepithelial photorefractive keratectomy(TPRK)and analyze their correlation.METHODS: The prospective study included 60 patients(120 eyes)with myopia and myopic astigmatism who underwent SPT-TPRK in the ophthalmology department at the First Affiliated Hospital of Xinxiang Medical University between February and August 2023. Changes in CET and CD were evaluated preoperatively and at 1 wk, 1 and 3 mo postoperatively.RESULTS: A total of 14 cases(28 eyes)were lost to follow-up, and 3 patients(6 eyes)with postoperative haze were excluded from this study, resulting in a final inclusion of 43 patients(86 eyes). At 1 wk after SPT-TPRK, CET had statistically significantly thickened compared to preoperative levels(P<0.05), particularly in the CET at 0-2 mm central corneal area(P<0.05). At 1 mo after SPT-TPRK, the CET at 0-2 mm area had statistically significantly decreased(P<0.05). At 3 mo after SPT-TPRK, the CET at 0-2 mm had essentially reached preoperative levels. Postoperative CD values increased, with a positive correlation between CET in the 0-2 mm area and CD in the whole 0-2 mm area(r=0.256, P<0.05), and a positive correlation between CET in the 2-5 mm area and CD in the anterior 2-6 mm area(r=0.319, P<0.05).CONCLUSION: Corneal epithelial remodeling takes 3 mo in areas within 2 mm of the central cornea; areas with thinner CET have faster postoperative corneal epithelial remodeling and greater thickening in the early postoperative period; CD increases in the early postoperative period compared to the preoperative value, and in some areas, there is a positive correlation between CET and CD value.

Objective:To explore the influencing factors of fetal growth restriction (FGR) in patients with preeclampsia (PE) and construct a Nomogram prediction model.Methods:From Aug. 2021 to May. 2023, 273 PE patients admitted to our hospital were regarded as the study subjects, and grouped into a modeling group (n=191) and a validation group (n=82). Multivariate logistic regression analysis was applied to determine the influencing factors of FGR in PE patients. R4.3.1 was applied to construct a Nomogram model for predicting FGR in PE patients. Receiver operating characteristic (ROC) curve and the Hosmer Lemeshoe (H-L) goodness of fit test were applied to evaluate the discrimination and consistency of the Nomogram model in predicting FGR in PE patients.Results:There was no statistically obvious difference in gestational age, blood pressure, hemoglobin, urinary protein (UP), uric acid, umbilical artery systolic/diastolic blood pressure (S/D), D-dimer (D-D), or birth frequency between the modeling group and the validation group ( P>0.05). Compared with no concurrent FGR group, the onset of pregnancy in the concurrent FGR group was earlier, the levels of UP, S/D, and D-D, and the proportion of oligohydramnios were obviously higher, and the platelet count (PLT) was obviously lower ( t/χ 2=2.588, 1.437, 6.262, 5.464, 9.881, 3.326, P<0.05). Multivariate Logistic regression analysis showed that UP, S/D, D-D, and oligohydramnios were risk factors for FGR in PE patients ( OR=1.004, 3.807, 1.006, 4.348, P<0.05), while PLT was a protective factor ( OR=0.980, P<0.05). Nomogram model showed that when the total score of the above 5 influencing factors in PE patients was 149, the probability of concurrent FGR was 60%; when the total score was 167, the probability of concurrent FGR was 90%, and the probability of exceeding 167 was over 90%. Modeling group H-L test χ 2=6.736, P=0.565, validation group χ 2=5.812, P=0.668. The area under the ROC curve (AUC) of the modeling group and the validation group was 0.924 (95% CI: 0.883-0.965) and 0.932 (95% CI: 0.880-0.984), respectively. The sensitivity was 83.93% and 90.48%, and the specificity was 89.63% and 81.97%, respectively. Decision curve analysis (DCA) was applied to evaluate the clinical application value of the Nomogram model in predicting FGR in PE patients. Conclusion:The Nomogram model constructed based on the five indicators of UP, S/D, D-D, PLT, and oligohydramnios for predicting the risk of FGR in PE patients has high discrimination and consistency.

Objective To analyze differential metabolites (DMs) in the urine of workers with occupational nickel exposure using non-targeted metabolomics, and to screen differential metabolic pathways. Methods A total of 30 nickel exposed workers were selected as the exposure group, and 30 administrative staff from the same factory were selected as the control group using the judgment sampling method. Urine samples of the individuals from the two groups were collected. The ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry and non-targeted metabolomics were used to detect and identify metabolites. The differential metabolic profiles were compared between workers of the two groups, and key differential metabolic pathways and potential biomarkers were screened. The association of DMs and urinary nickel level were evaluated by Spearman correlation coefficients. The sensitivity and specificity of biomarkers were assessed by receiver operating characteristic (ROC) curve analysis. Results A total of 418 metabolites were identified in the urine of worker in the exposure and control groups. The result of principal component analysis and orthogonal partial least squares analysis showed that there were 128 DMs in the urine of workers in the exposure group compared with the control group. These DMs were mainly enriched in glutathione metabolism, carnitine synthesis, and amino acid and nucleotide metabolism pathways, including glycine and serine metabolism. The result of correlation analysis and ROC curve analysis revealed that 4-methylcatechol, 4-vinylphenol sulfate, 2-hydroxyphenylacetone sulfate, 2-dodecylbenzenesulfonic acid, and decylbenzenesulfonic acid could be the potential biomarkers for nickel exposure (all area under the ROC curve >0.800). Conclusion There were significant differences in the urinary metabolic profiles of workers with occupational nickel exposure. The five DMs including 4-methylcatechol, 4-vinylphenol sulfate, 2-hydroxyphenylacetone sulfate, 2-dodecylbenzenesulfonic acid, and decylbenzenesulfonic acid. These DMs could be potential biomarkers of occupational nickel exposure.

Background:
Gout is the most prevalent form of inflammatory arthritis in the world. Total hip arthroplasty (THA) has emerged as a widely sought-after and highly effective surgical procedure for advanced hip diseases. However, there is a lack of research on the impact of gout on primary THA outcomes in large cohorts. This study aimed to address this gap by primarily investigating complications following THA in patients with or without gout.
Methods:
Patients with records of gout in the 2 years leading up to their primary THA and who also have at least 2 years of follow-up were identified using a national insurance database and compared to a 5:1 matched control. A total of 32,466 patients with gout and 161,514 patients without gout undergoing THA were identified. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to 2 years. In addition, 90-day emergency department (ED) visits and inpatient readmission were also documented.
Results:
Patients with gout demonstrated higher rates of medical complications including deep vein thrombosis, transfusion, acute kidney injury, and urinary tract infection than non-gout patients (p < 0.001). Gout patients also showed higher rates of pulmonary embolism (p = 0.017). Increased incidences of surgical complications were identified in gout patients, specifically wound complications and periprosthetic joint infection (p < 0.001). There was an increased risk of revision for gout patients up to 90 days (p = 0.003), 1 year (p = 0.027), and 2 years (p = 0.039). There was also an increased risk of dislocation for gout patients up to 90 days (p = 0.022) and 1 year (p = 0.047), but not at 2 years. No significant difference was observed in aseptic loosening or periprosthetic fracture. Additionally, gout patients also demonstrated a higher likelihood of 90-day ED visits and readmission (p < 0.001).
Conclusions
Primary THA in gout patients is associated with increased risks of multiple medical and surgical complications. Our findings provide insights into the planning and expectation of THA for patients with gout. These insights have the potential to benefit the decision-making process for gout patients considering THA.

【Objective】 To analyze the related factors of emotional and behavioral abnormalities in children with overactive bladder (OAB). 【Methods】 OAB children (aged 6 to 16 years) in a survey of 5 032 children from a county in Henan Province during Sep.2022 and Dec.2022 were identified and surveyed with Overactive Bladder Symptom Score (OABSS), Strength and Difficulties Questionnaire (SDQ) and Pediatric Sleep Questionnaire (PSQ). According to the SDQ score, they were divided into abnormal group (SDQ≥20) and normal group. 【Results】 There were 35.7%(137/385) cases in the abnormal group and 64.3% (248/385) in the normal group. Gender, education level of caregivers, body mass index (BMI), age, constipation, enuresis and severity of OAB were significantly associated with emotional and behavioral abnormalities (P<0.05). Children in the abnormal group showed significant differences in emotional symptoms, conduct problems, hyperactivity symptoms, peer interaction and sleep (P<0.001). Multivariate regression analysis revealed significant differences in gender, educational level of caregi-vers, BMI, age, constipation, enuresis, severity of OAB and PSQI between the two groups (P<0.05). 【Conclusion】 The prevalence of emotional and behavioral abnormalities is high in children with OAB, which is related to female gender, high BMI, puberty, constipation, enuresis and severity of OAB.

Objective To establish a method for the determination of thallium and its soluble compounds in workplace air using microporous filter membrane sampling and inductively coupled plasma mass spectrometry (ICP-MS). Methods Thallium and its soluble compounds in workplace air were collected using microporous filter membranes, digested with nitric acid, quantified using lutetium internal standard method, and detected by ICP-MS. Results The linear range of thallium was 0.00 to 600.00 μg/L, with the correlation coefficient of 1.000. The detection limit was 0.08 μg/L, and the lower limit of quantification was 0.26 μg/L. The minimum detection concentration and minimum quantitation concentration of thallium of 75.00 L workplace air were 1.0×10-5 and 3.0×10-5 mg/m3, respectively. The minimum detection concentration and minimum quantitation concentration of thallium of 480.00 L workplace air was 2.0×10-6 and 5.0×10-6 mg/m3, respectively. The recovery rate of spiking was 100.82%-103.44%, and the relative standard deviation within- and between-batches was 1.50%-3.32% and 1.32%-3.11%, respectively. The sample could be stored at room temperature for at least 14 days. Conclusion This method can be used for the detection of thallium and its soluble compounds in workplace air.

Objective:To explore the effect of health education based on theory of planned behavior combined with stepped care model on negative emotion, psychological flexibility and quality of life in patients with lung cancer undergoing chemotherapy.Methods:From October 2020 to December 2021, 108 chemotherapy patients who underwent lung cancer surgery in Affiliated Hospital of Weifang Medical College and had anxiety or depression that scores was greater than 7 in any dimension of the Hospital Anxiety and Depression Scale (HADS) were selected as the study subjects. The study subjects were divided into observation group ( n=46) and control group ( n=48) by random digits table method. Routine care was implemented in the control group. The observation group implemented health education based on the theory of planned behavior combined with stepped care model intervention. The HADS scale was used every 4 weeks to assess negative emotion in both groups. In observation, patients with negative emotion relief stop the next stage of nursing intervention, and patients without relief continue the next stage of higher intensity nursing intervention. Results:Before the intervention, there were no significant difference in the scores of negative emotion, psychological flexibility and quality of life between the two groups ( P>0.05). After intervention, the scores of all dimensions of negative emotion and the total score in the observation group were significantly lower than those in the control group, and the differences had statistical significance ( t=4.86, 3.19 and 4.53, all P<0.05). After the intervention the scores of psychological flexibility and quality of life dimensions and the total score in the observation group were higher than those in the control group, the differences had statistical significance (t values were -6.01--2.89, all P<0.05). After the intervention, there was no significant difference in the remission rate of negative emotions between the clinical observation stage of the observation group and the concurrent control group ( P>0.05). The remission rates of guided self-help, problem-solving therapy, psychological or drug therapy and total negative emotions in the observation group were 38.46%(15/39), 33.33%(8/24), 6/16 and 78.26%(36/46), respectively, which were higher than those in the control group, and the differences had statistical significance ( χ2 values were 7.04 - 13.80, all P<0.05). Conclusions:Health education based on the theory of planned behavior combined with stepped care model can effectively alleviate the negative emotions of lung cancer patients undergoing chemotherapy and improve psychological flexibility and quality of life.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.
