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.

ObjectiveTo explore the clinical efficacy and safety of Fuzheng Huaji Longbi decoction in treating benign prostatic hyperplasia （BPH） in the patients with the syndrome of healthy Qi deficiency and blood stasis. MethodA total of 94 BPH patients were randomized into control and observation groups， with 47 patients in each group. The control group was treated with doxazosin mesylate sustained-release tablets， and the observation group with Fuzheng Huaji Longbi decoction on the basis of the therapy in the control group. After eight weeks， the international prostate symptom score （IPSS）， quality of life （QOL） score， residual urine volume （RUV）， maximum urinary flow rate （Q_max）， TCM syndrome score， TCM symptom score， electrocardiogram， and liver and kidney function were determined to evaluate the clinical efficacy and safety of the two groups. ResultAfter 8 weeks of treatment， the total response rate in the control group was 63.64% （28/44）， which was lower than that （84.44%， 38/45） in the observation group （χ²=5.026， P<0.05）. The clinical efficacy in the observation group was higher than that in the control group （Z=-2.17， P=0.030）. The treatment in both groups decreased the IPSS， QOL score， RUV， and TCM syndrome scores and increased the Q_max （P<0.05）. Moreover， the observation group had lower IPSS， QOL score， RUV， and TCM syndrome score （P<0.05） and higher Q_max than the control group after treatment （P<0.05）. The treatment in the observation group decreased all the TCM symptom scores （P<0.05）， while that in the control group only decreased the frequency of urination at night and the scores of dysuria， weak urine stream， and post-urinary drainage （P<0.05）. After treatment， the observation group had lower frequency of urination at night and lower scores of mental fatigue， cold limbs， lower abdominal discomfort， and loose stool than the control group （P<0.05）. No adverse events associated with the administration of Fuzheng Huaji Longbi decoction were observed during the treatment period. ConclusionFuzheng Huaji Longbi decoction is effective in treating BPH in the patients with the syndrome of healthy qi deficiency and blood stasis. It can relieve the clinical symptoms and improve the quality of life， being a safe and reliable choice for clinical application.

A large number of non-specific immune cells, such as macrophages, neutrophils and natural killer cells, as well as specific immune cells, such as B cells and T cells, are presented in the atherosclerotic plaques and arterial blood. In addition, immune-related regulatory molecules such as interferon-γ, interleukin-17, and interleukin-1β highly express in atherosclerotic lesion tissues, which is similar to the tumor immune microenvironment and influence the atherosclerosis progression. In this paper, the research progress of immune cells and related factors involved in the immune microenvironment around cerebral atherosclerotic lesions is reviewed to provide idea and basis for its clinical diagnosis and treatment.

Objective:To explore the mechanism of Fuyuan Xingnao Decoction in treatment of cerebral infarction based on network pharmacology and molecular docking.Methods:The active components and action targets of Fuyuan Xingnao Decoction were screened by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP),Traditional Chinese Medicine Integrated Database (TCMID),Bioactivity data of small organic molecules (PubChem),Universal Protein (Uniprot) and Swiss Target Prediction database platform. The databases of GeneCards, Online Mendelian Inheritance in Man (OMIM), Therapeutic Target Database (TTD), and Drug Bank and Pharmacogenomics Knowledgebase (PharmGKB) were used to screen targets of cerebral infarction. The drug target genes in Fuyuan Xingnao Decoction were intersected with those of cerebral infarction, the intersecting targets were introduced into Cytoscape 3.8.2 software to construct the component target network, and the PPI protein interaction network was constructed by using STRING analysis platform and Cytoscape 3.8.2 software to screen the core targets. Gene Ontology (GO) function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) function enrichment analysis were carried out on the common target genes of Fuyuan Xingnao Decoction and cerebral infarction disease to obtain the relevant signal pathways. Finally, AutoDock and Pymol software were used for molecular docking between the predicted target and its corresponding components.Results:After screening, 80 effective components of Fuyuan Xingnao Decoction for treatment of cerebral infarction and 214 common targets of Fuyuan Xingnao Decoction and cerebral infarction were obtained. The core targets such as MAPK1, RELA, TP53, JUN, AKT1 and HSP90AA1 were related to the key targets of cerebral infarction, and they participated in the biological process of regulating the response to drugs, lipopolysaccharide and oxygen level, etc. The cell composition involved membrane raft, membrane micro region and nerve cell body, etc. Molecular functions mainly focused on nuclear receptor activity, ligand activated transcription factor activity, DNA binding transcription factor binding, etc.; it also involved in signal pathway of lipid and atherosclerosis, chemical carcinogen and receptor activation, fluid shear stress and atherosclerosis, etc. Molecular docking showed that good binding activities were seen between Quercetin and HSP90AA1 (-9.4 kJ/mol), between Kaempferol and HSP90AA1 (-9.4 kJ/mol), between Isorhamnetin and HSP90AA1 (-9.1 kJ/mol), and between Quercetin and JUN (-8.6 kJ/mol).Conclusion:Fuyuan Xingnao Decoction can prevent and treat cerebral infarction by regulating vascular endothelial function, promoting blood circulation, repairing and improving neural function, protecting blood-brain barrier, reducing cell apoptosis, and regulating immune and inflammatory response.

Objective:To analyze the risk factors of clinically significant bleeding in patients with severe acute pancreatitis (SAP).Methods:The clinical data of SAP patients who were managed at Changhai Hospital affiliated to Naval Medical University from January 1, 2014 to October 31, 2022 were retrospectively analyzed. Twenty-nine SAP patients with clinically significant bleeding were classified to form the bleeding group. There were 23 males and 6 females, aged (56.25±14.01) years old. Another 116 SAP patients with similar general data but with no clinically significant bleeding during the same hospitalization period were included to form the non-bleeding group based on a ratio of 1∶4. There were 94 males and 22 females, aged (56.14±13.96) years old in this non-bleeding group. The general data, modified CT severity index (MCTSI), bedside index for severity of acute pancreatitis (BISAP) and other clinical data of the two groups were collected to determine the risk factors of bleeding in SAP patients.Results:Of the 29 patients with bleeding, 6 had gastrointestinal bleeding, 14 had intra-abdominal bleeding, and 9 had mixed bleeding sites, 15 were cured and discharged, and 14 died. All the 29 SAP patients with bleeding received treatment using drugs. In addition, 8 patients underwent successful hemostasis using digital subtraction angiography, 3 underwent successful endoscopic hemostasis, 2 underwent successful surgical hemostasis, and 2 underwent successful conservative drug hemostasis. Multivariate logistic regression analysis showed that SAP patients with higher MCTSI ( OR=1.824, 95% CI: 1.187-2.802), longer prothrombin time (PT) ( OR=3.431, 95% CI: 1.470-8.007) and higher BISAP ( OR=2.286, 95% CI: 1.054-4.957) had an increased risk of bleeding (all P<0.05). Conclusion:The prognosis of SAP patients was compromised with bleeding. High MCTSI, prolonged PT, and high BISAP were independent risk factors for bleeding in SAP patients.

Shengmai formula,composed of Ginseng Radix et Rhizoma,Ophiopogon Radix and Schisandrae Chinensis Fructus,is a classic and famous formula.It is a representative formula for"supplementing qi,nourishing yin,and generating fluid"in Traditional Chinese Medicine theory.To date,a wide range of Shengmai formulae have been developed according to different medical applications,but the quality evaluation standards are at a relatively low level,and most of them only specify the individual components of a single herb,making it difficult to ensure clinical efficacy and safety.At the same time,the physical and chemical identification methods of Shengmai formula have been constantly updated,allowing for greater progress in research on its main chemical components such as saponins,lignans and flavonoids.However,there is little systematic summarization of the chemical components and analytical methods.Based on the existing references,we systematically summarized ginsenosides,ophiopogonins,schisandra lignans,homoisoflavonoids and some other compounds in this paper,as well as the quality standards of Shengmai formulae and their analytical methods in order to aid clinical research and formulation manufacture.

Objective:To analyze the incidence and mortality trends of female breast cancer in China from 1990 to 2019 and the impact of age-period-cohort (APC) on it.Methods:The incidence and mortality of breast cancer of Chinese women aged 20-95 years from 1990 to 2019 were collected from the Global Burden of Disease (GBD) in 2019. Joinpoint software was used to estimate the average annual percentage change rate (AAPC) of age standardized incidence and mortality, and analyze the changing trend of disease burden of breast cancer in Chinese women from 1990 to 2019. The R language based APC model developed by the National Cancer Institute of the United States was used to analyze the impact of age, period and cohort on their changes.Results:From 1990 to 2019, the age standardized incidence of female breast cancer in China showed an upward trend, from 17.07/100 000 in 1990 to 35.61/100 000 in 2019, with an average annual increase of 2.59% (95% CI: 2.45%-2.73%, P<0.001) , which was higher than the global level (AAPC=0.47%, 95% CI: 0.31%-0.63%, P<0.001) . The standardized mortality showed a slight downward trend, from 9.16/100 000 in 1990 to 9.01/100 000 in 2019, with a decrease of 0.05% (95% CI: -0.20%-0.09%, P=0.479) , but there was not a statistically significant difference. APC model results showed that the incidence and mortality of female breast cancer increased with age. With the passage of time, the incidence from 1990 to 2019 showed an upward trend, and the incidence risk rose to 1.49 in the 2015-2019 period (95% CI: 1.42-1.57, P<0.001) . The mortality showed a downward trend, and the death risk was the highest in the 1990-1994 period ( RR=0.79, 95% CI: 0.74-0.83, P<0.001) . Cohort effect results showed that the later the women were born, the higher the risk of morbidity. The women born in the cohort from 1995 to 1999 had the highest risk ( RR=3.12, 95% CI: 1.82-5.33, P<0.001) . The risk of death showed a unimodal distribution, showing a trend of first increasing and then decreasing, the later the women were born, the lower the risk of death. The birth cohort from 1950 to 1954 had the highest risk of death ( RR=1.04, 95% CI: 0.98-1.09, P<0.001) , and then showed a downward trend, falling to 0.48 (95% CI: 0.19-1.24, P<0.001) in the birth cohort from 1995 to 1999. Conclusion:From 1990 to 2019, the incidence of breast cancer in Chinese women shows an upward trend, which is significantly higher than the global increase, and the mortality tends to stabilize. APC model analysis finds that the incidence and mortality increase with age, and the period and cohort effects show that the incidence risk of breast cancer in Chinese women gradually increases with the passage of the period and cohort. The period effect of mortality shows a downward trend, and the cohort effect of mortality shows a unimodal distribution, showing a trend of first increasing and then decreasing.

Objective:To systematically review the efficacy of ultrasound-guided fluid resuscitation and early goal-directed therapy (EGDT) in patients with septic shock.Methods:Multiple databases including Wanfang, CNKI, SinoMed, VIP, PubMed, Embase, Cochrane Library and Web of Science were searched from initial to August 2019 for randomized controlled trial (RCT) studies about the comparison of ultrasound-guided fluid resuscitation and EGDT on resuscitation effect in patients with septic shock. Language, country and region were unlimited. Data extraction and quality evaluation were carried out by means of independent review and cross check results by two researchers.Results:Finally, only two English RCT studies were enrolled. In the two RCT studies, the ultrasound groups used inferior vena cava collapse index (VCCI) and ultrasound score to guide fluid resuscitation, which resulted in clinical heterogeneity. Because the results could not be pooled, only systematic review, not meta-analysis, could be done. There were measurement bias and selection bias in the two RCT studies, and the literature quality level was B and C respectively. System review results showed that using ultrasound would reduce 7-day mortality (15.0% vs. 35.0%, P = 0.039) and prescribe less of 24-hour intravenous fluids (mL: 900 vs. 1 850, P < 0.01) for patients with septic shock as compared with EGDT. Ultrasound was easy to assess the reactive capacity and cardiac function of patients with septic shock, so as to decrease the incidence of pulmonary edema, which was significantly lower than EGDT (15.0% vs. 37.5%, P = 0.022). However, there was no statistically significant difference in 28-day mortality, duration of mechanical ventilation or length of intensive care unit (ICU) stay between the two groups. Conclusion:The ultrasound-guided fluid resuscitation may be useful and practical for septic shock patients within 7 days after admission as compared with EGDT, but it cannot reduce the 28-day mortality, duration of mechanical ventilation or length of ICU stay.

Sepsis and septic shock are important clinical problems in critically ill patients, accounting for the first cause of death in intensive care unit (ICU). Therefore, early diagnosis and treatment are particularly important. Recently, genome-wide expression analysis of non-coding RNA in septic patients showed that more than 80% were differentially expressed compared with healthy individuals. These molecules play important roles in biological processes, including innate immunity, mitochondrial function and apoptosis. Therefore, a class of non-coding RNAs such as microRNA (miRNA), long-chain non-coding RNA (lncRNA) and circular non-coding RNA (circRNA) are increasingly recognized as a regulator of various signaling pathways. The potential of regulatory non-coding RNA target to treat sepsis was discussed by studying non-coding RNAs that might serve as molecular markers of sepsis, and its clinical value was evaluated.

Objective: To evaluate the prevalence and risk factors of aortic valve calcification among the elderly (≥65 years old) resident of Wuxi city, Jiangsu province. Methods: The household registration population aged ≥65 years old in Wuxi city was selected as the research subject by stratified sampling method from August 2017 to December 2018. Echocardiography was performed to assess the aortic valve calcification, and the participants were divided into calcification group and non-calcification group. Multivariate logistic regression analysis was used to explore the related risk factors of aortic valve calcification. Results: The age of the respondents was (73.6±7.1) years old, of which 48.8% (461 cases) were males.The prevalence rate of aortic valve calcification was 22.0% (208/944) in the elderly (≥ 65 years old) residents in Wuxi city. The prevalence rate in 65-69 years old, 70-74 years old, 75-79 years old, 80-84 years old and ≥85 years old was 16.7% (58/347),16.7% (41/245),16.2% (26/161),23.3% (24/103), and 67.0% (59/88),respectively. There were significant differences in age, weight, abdominal circumference, hip circumference, high-salt diets, exercise, hypertension, hyperlipidemia, diabetes, coronary heart disease, cerebrovascular disease, and carotid atherosclerosis between the non-calcified group (736 cases) and the calcified group (208 cases) (P<0.01 or 0.05).Multivariate logistic regression analysis showed that age (OR=1.077, 95%CI 1.053-1.101, P<0.001), diabetes mellitus (OR=1.697, 95%CI 1.174-2.453, P=0.005), and coronary heart disease (OR=1.964, 95%CI 1.378-2.799, P<0.001) were the risk factors of aortic valve calcification. Conclusions The prevalence of aortic valve calcification in the elderly (≥65 years old) residents in Wuxi city of Jiangsu province increases with aging. Age, diabetes mellitus and coronary heart disease are the risk factors of aortic valve calcification in this population cohort.
