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.

Objective To discuss the feasibility and safety of simultaneous bilateral adrenal vein sampling(AVS)using two 4F-MPA1 catheters via right elbow vein access.Methods A total of 51 consecutive patients with primary aldosteronism,who received simultaneous bilateral AVS using two 4F-MPA1 catheters(one of the two catheters was shaped into pig tail figure)via right elbow vein access at Xiangyang Municipal Central Hospital between October 2021 and October 2022,were enrolled in this study.The used catheter,the success rate of simultaneous bilateral AVS,and the incidence of complications rate were calculated.Results The 4F-MPA1 catheter was used for all of the right AVS,while a specially shaped 4F-MPA1 catheter was used for the main trunk vein AVS of the left adrenal gland and the central vein AVS of the left adrenal gland.The success rate of simultaneous bilateral AVS was 92.2%(47/51).Adrenal hematoma occurred in one patient(1.96%).Conclusion The technique of simultaneous bilateral AVS using two 4F-MPA1 catheters via right elbow vein access is simple to operate,less traumatic,and clinically safe and feasible.However,due to the small sample used in this study,the clinical value of this technique still needs further investigation and verification.

Objective To observe the effects of Yiqi Huoxue Tuodu Prescription on Keap1Nrf2/HO-1 signaling pathway in rats with chronic nonbacterial prostatitis(CNP);To explore its mechanism for the treatment of CNP.Methods CNP rat model was prepared using castration combined with estrogen induction method.Totally 48 SD rats were divided into blank group,model group,celecoxib group and Yiqi Huoxue Tuodu Prescription group according to the random number table method,with 12 rats in each group.In the celecoxib group,celecoxib suspension was instilled 0.035 g/kg,and in the Yiqi Huoxue Tuodu Prescription group,Yiqi Huoxue Tuodu Prescription water decoction was instilled 8.64 g/kg,and the blank group and the model group were instilled with equal volume of normal saline for 28 days.Mechanical pain threshold in rats was measured using Von Frey fiber optic pain gauge,HE staining was used to observe pathological changes in prostate tissue and pathological scoring,the content of reactive oxygen species(ROS)in prostate tissue were detected by chemical fluorescence method and the glutathione peroxidase(GSH-Px)activity and malondialdehyde(MDA)content in prostate tissue were detected by colorimetric method,Western blot was used to detect the expressions of Kelch like ECH related protein 1(Keap1),nuclear factor E2 related factor 2(Nrf2),and heme oxygenase-1(HO-1)protein in prostate tissue.Results Compared with the blank group,rats in the model group had significantly lower mechanical pain threshold and significantly decreased prostate index(P<0.01);the size of the glandular cavity in prostate tissue varied,with the disappearance of secretions in the cavity,interstitial looseness and edema,a large amount of fibrous tissue hyperplasia and inflammatory cell infiltration,and a significant increase in pathological scores(P<0.01);the contents of ROS and MDA in prostate tissue significantly increased,the activity of GSH-Px significantly decreased(P<0.01),the expression of Keap1 and Nrf2 proteins significantly decreased,and the expression of HO-1 protein significantly increased(P<0.01,P<0.05).Compared with the model group,the mechanical pain threshold of the rats in the Yiqi Huoxue Tuodu Prescription group was significantly higher(P<0.01);there was mild damage to prostate tissue,with a small amount of fibrous hyperplasia and inflammatory cell infiltration,and a significant decrease in pathological scores(P<0.01,P<0.05);the contents of ROS and MDA in prostate tissue significantly decreased,and the GSH-Px activity significantly increased(P<0.01),the Keap1 and Nrf2 protein expressions significantly increased and HO-1 protein expression significantly decreased in prostate tissue(P<0.01,P<0.05).Conclusion Yiqi Huoxue Tuodu Prescription can effectively improve the histopathological morphology and increase the pain threshold of the prostate gland in CNP rats,and its mechanism of action may be related to the regulation of Keap1/Nrf2/HO-1 signaling pathway and reduction of oxidative stress damage in prostate tissue of rats.

Male lower urinary tract symptoms is a collective term for a group of symptoms associated with lower urinary tract disorders characterized by frequent urination, urgent urination, and difficulty of urination, of which the common causes are benign prostatic hyperplasia or overactive bladder. With the aging of the global population, the incidence of male lower urinary tract symptoms is increasing year by year. Based on the theoretical connotation of " zang-fu extraordinary connection", the relationship between the lungs and the bladder, the spleen and the small intestine, and the kidneys and the sanjiao with the formation of male lower urinary tract symptoms is explained from three perspectives. It is believed that lung qi depression and closure, disturbance of qi transformation in bladder, and insufficient spleen transport occur, the small intestine is dysfunctional, kidney yang is exhausted, and obstruction of the sanjiao waterway are the basic pathogenesis of male lower urinary tract symptoms. It is emphasized that the location of the disease should be identified. If it is related to the lungs and the bladder, then the disease should be treated by lifting the pot to lift the lid and diffusing the lung qi to benefit the bladder with Wuling Powder plus perilla leaf and bitter apricot seed; if it is related to the spleen and the small intestines, then the disease should be treated by raising the clear and directing the turbid downward and improving the spleen qi in order to support the small intestines with Shenling Baizhu Powder; if it is related to the kidneys and the sanjiao, then the disease should be treated by seeking the yang within the yin and warming and tonifying the kidney qi in order to dredge up the sanjiao with Bawei Shenqi Pill. According to the patient's condition, treatment can be combined with acupuncture, exercise, and other therapies. This paper can provide reference for clinical treatment of male lower urinary tract symptoms.

Objective:To summarize the genotype and clinical characteristics of chylomicron retention disease (CMRD) caused by secretion associated Ras related GTPase 1B (SAR1B) gene variations.Methods:Clinical data and genetic testing results of 2 children with CMRD treated at Children′s Hospital of Fudan University and Jiangxi Provincial Children′s Hospital from May 2022 to July 2023 were summarized. To provide an overview of the clinical and genetic characteristics of CMRD caused by SAR1B gene variations, all of the literature was searched and reviewed from China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China VIP database, China Biology Medicine disc and PubMed database (up to January 2024) with "chylomicron retention disease" "Anderson disease" or "Anderson syndrome" as the search terms. All relevant literatures were reviewed to summarize the clinical and genetic features of CMRD caused by SAR1B gene variations.Results:One 11-year-old boy and one 4-month-old girl with CMRD. Both patients had lipid malabsorption, failure to thrive, decreased cholesterol, elevated transaminase and creatine kinase, and Vitamin E deficiency, with homozygous variations (c.224A>G) and compound heterozygous variations (c.224A>G and c.554G>T) in SAR1B gene, respectively. Case 1 was followed up for over a month, and he still occasionally experienced lower limb muscle pain. Case 2 was followed up for more than a year, and her had caught up to normal levels. Both patients had no other significant discomfort. Literature search retrieved 0 Chinese literature and 22 English literatures. In addition to the 2 cases reported in this study, a total of 51 patients were identified as CMRD caused by SAR1B gene variations. Twenty-one types of SAR1B variants 10 missense, 4 nonsense, 3 frameshift, 1 in-frame deletion, 1 splice, 1 gross deletion, and 1 gross insertion-deletion were found among the 51 CMRD cases. Among all the patients, 49 cases had lipid malabsorption (43 cases had diarrhea or fatty diarrhea, 17 cases had vomiting, and 12 cases had abdominal distension), 45 cases had lipid soluble Vitamin deficiency (43 cases had Vitamin E deficiency, 10 cases had Vitamin A deficiency, 9 case had Vitamin D deficiency, and 5 cases had Vitamin K deficiency), 35 cases had failure to thrive, 32 cases had liver involvement (32 cases had elevated transaminases, 5 cases had fatty liver, and 3 cases had hepatomegaly), 29 cases had white small intestinal mucosa under endoscopy, and 17 cases had elevated creatine kinase, 14 cases had neuropathy, 5 cases had ocular lesions, 2 cases had acanthocytosis, 1 case had decreased cardiac ejection fraction, and 1 case was symptom-free.Conclusions:Early infancy failure to thrive and lipid malabsorption are common issues for CMRD patients. The laboratory tests are characterized by hypocholesterolemia with or without fat-soluble Vitamin deficiency, elevated liver enzymes and (or) creatine kinase. Currently, missense variations are frequent among the primarily homozygous SAR1B genotypes that have been described.

Objective To compare the clinical effects of minimally invasive percutaneous plate osteosynthesis (MIPO) and minimally invasive intramedullary nailing osteosynthesis (MINO) in the treatment of humeral shaft fractures. Methods The clinical data of 53 patients with humeral shaft fractures treated with MIPO and MINO were retrospectively analyzed. The patients were divided into MIPO group of 25 patients and MINO group of 28 patients according to differed surgical approaches. The operation time, blood loss, length of hospital stay, fracture healing time, University of California at Los Angeles (UCLA) shoulder function score at 1 year postoperatively, and Mayo elbow performance score at 1 year postoperatively were compared between the two groups. Results All 53 patients successfully completed the surgery, and no postoperative complications such as surgical site infection, radial nerve injury, fracture nonunion, implant breakage, or loosening occurred. There were no statistically significant differences between the two groups in terms of operation time, blood loss, length of hospital stay, fracture healing time, and Mayo elbow performance score at 1 year postoperatively (P>0.05). The UCLA shoulder function score at 1 year postoperatively was better in the MIPO group than in the MINO group (P < 0.05). One patient in the MIPO group experienced wound fat liquefaction, and one patient in the MINO group experienced radial nerve palsy. Conclusion Both MIPO and MINO can achieve satisfactory results in the treatment of humeral shaft fractures, and both minimally invasive techniques are worthy of clinical promotion. However, MIPO has lesser impact on shoulder function.

Objective:To investigate the value of the 8-channel eye surface phased array coil in improving image quality and demonstrating ocular masses on 3.0 T MR scanner.Methods:From July 2018 to January 2020, the data of orbital MRI in 692 patients with ocular masses on 6 medical centers were prospectively collected. The patients were simple randomly assigned into 8-channel eye surface phased array coil group (413 patients) or 8-channel head phased array coil group (279 patients), with the same MRI sequences. The signal to noise ratio (SNR) and contrast to noise ratio (CNR) were calculated in orbital anatomy structures and masses (eyelid mass, intraocular mass, lacrimal mass and orbital mass). The image quality scores including motion artifact, mass margin, the relationship between the mass and adjacent structures, and overall image quality were recorded. The differences of image quality between the two groups were compared by two independent sample t-test or Wilcoxon rank test. Results:The SNR and CNR were higher in eye surface coil group than those in head coil group ( P<0.05). The scores of ocular movement artifacts were higher in head coil group than those in surface coil group ( P<0.05). The scores of intraocular mass margin, the relationship between the mass and adjacent structures, and overall image quality were higher in surface coil group than those in head coil group ( P<0.001). There were no significant differences in mass margin, the relationship between the mass and adjacent structures, and overall image quality scores of eyelid, lacrimal gland, and orbital mass between the two groups ( P>0.05). Conclusion:3.0 T MR scanner combined with the 8-channel eye surface phased array coil can improve the SNR and CNR of orbital MR images, the demonstration of the intraocular mass margin and the relationship between the mass and adjacent structures.

Objective To evaluate the effect of an empathy intervention program based on 5-step empathetic model(5-SEM)on stress response,anxiety and depression,and sleep quality among patients with acute cerebral infarction.Methods The 100 participants were admitted to the Second Affiliated Hospital of Wenzhou Medical University from November 2022 to April 2023.According to the admission time,they were divided into two groups,with 50 cases in each group.The patients in the control group received normal care,while those in the observation group underwent an empathy intervention program based on 5-SEM.This program includes the establishment of an empathetic intervention team,comprised of physicians,psychologists,head nurses,and nurses with more than 5 years of work experience and a bachelor's degree or higher.The intervention team,based on searches and collation of relevant literature from databases such as CNKI,Wanfang Data,the National Library of Medicine's PubMed database,and the Dutch medical abstracts EMBase database,is responsible for assessing patient conditions.A final draft of the empathetic intervention plan based on the 5-SEM is then formed by the supervising nurse.nurses in the empathetic intervention team was responsible for implementing the 5-SEM intervention plan.The outcomes were evaluated by Athens insomnia scale(AIS),hospital anxiety and depression scale(HADS),and stress response questionnaire(SRQ).Results After intervention,the scores for sleep quality,anxiety and depression,and stress response in both groups showed a significant decrease compared to pre-intervention[sleep quality scores:control group was 6.74±1.77 vs.12.08±2.94,observation group was 4.84±2.04 vs.11.90±2.80;anxiety scores:control group was 7.14±2.20 vs.8.58±2.38,observation group was 6.06±2.47 vs.8.34±2.03;depression scores:control group was 7.28±2.12 vs.8.72±2.34,observation group was 6.26±2.03 vs.8.82±2.80;physical reaction scores:control group was 17.72±4.29 vs.22.94±3.73,observation group was 16.10±3.19 vs.22.62±3.25;emotional reaction scores:control group was 21.82±2.98 vs.26.80±3.21,observation group was 20.60±2.45 vs.26.32±4.32;behavioral reaction scores:control group was 12.68±1.75 vs.15.46±3.18,observation group was 11.16±1.98 vs.14.90±2.24;stress response scores:control group was 55.40±4.89 vs.69.46±6.28,observation group was 50.98±4.68 vs.68.08±6.18,all P<0.05],post-intervention,the scores in the observation group were significantly lower than those in the control group(all P<0.05).Conclusion The empathy intervention program based on the 5-SEM could alleviate anxiety,depression,and stress responses among patients with acute cerebral infarction,while also improving sleep quality.

Objective:To construct the quality evaluation system for tracheal extubation in the patients undergoing general anesthesia based on zero-defect management theory.Methods:Based on the model of zero-defect theory, literature review, semi-structured interviews, expert consultation and analytic hierarchy process were used to determine the content and weight of each index of the quality evaluation system for tracheal extubation in the patients undergoing general anesthesia.Results:The effective recovery rates of the two rounds of expert consultation questionnaires were 93% and 96% respectively; the expert authority coefficients were 0.946 and 0.947 respectively; the Kendall harmony coefficients were 0.247 and 0.250 respectively ( P<0.001). The final evaluation index system included 3 first-level indicators, 11 second-level indicators and 48 third-level indicators.The consistency coefficients of indicators at all levels were <0.1.

Objective:To analyze independent influencing factors of surgical textbook outcome (TO) in patients with gallbladder carcinoma, and to establish a nomogram for predicting TO and evaluated the predictive ability.Methods:Patients with gallbladder carcinoma who underwent surgery in Department of Hepatobiliary and Pancreatic Surgery at Dongfang Hospital Affiliated to Shanghai Tongji University and Department of Biliary Tract Surgery Ⅰ, Third Affiliated Hospital of Naval Medical University (Shanghai Eastern Hepatobiliary Surgery Hospital) from January 2013 to December 2018 were included and the clinical features were retrospectively analyzed. A total of 232 patients were included, including 114 males and 118 females, aged (61.0±9.8) years. According to whether TO reached or not, they were divided into TO group ( n=86) and non-TO group ( n=146). Univariate and multivariate logistic regression were used to analyze the independent influencing factors of TO. The predictive nomogram model of TO was constructed. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive ability of the model, and the consistency of the predictive model was evaluated by the consistency curve graph and the Hosmer-Lemeshow test. Results:The 1-year and 3-years cumulative survival rates of patients with gallbladder carcinoma in the TO group (86.0% and 62.8%) were better than those in the non-TO group (46.6% and 27.3%), and the difference was statistically significant (χ 2=60.74, P<0.001). In multivariate analysis, higher T stage ( OR=0.16, 95% CI: 0.03-0.79, P<0.001) and cervical gallbladder cancer ( OR=0.14, 95% CI: 0.02-0.94, P=0.004) had the greatest negative association with a TO, and the higher the degree of tumor differentiation ( OR=7.08, 95% CI: 1.34-37.56, P=0.001), the easier it is to achieve TO. The ROC curve showed that the area under the curve of the predictive model was 0.84 (95% CI: 0.79-0.90), suggesting that the model had good predictive performance. A nomogram to assess the probability of TO was developed and had good accuracy in both the consistency curve and Hosmer-Lemeshow test (χ 2=5.77, P=0.673). Conclusion:Tumor T stage, tumor differentiation degree and tumor location are independent influencing factors for achieving TO in patients with gallbladder carcinoma after surgery. The nomogram model constructed according to the above conclusions could accurately predict the probability of reaching TO.
