Targeted covalent inhibitors, primarily targeting cysteine residues, have attracted great attention as potential drug candidates due to good potency and prolonged duration of action. However, their discovery is challenging. In this research, a database-assisted liquid chromatography-tandem mass spectrometry (LC-MS/MS) strategy was developed to quickly discover potential cysteine-targeting compounds. First, compounds with potential reactive groups were selected and incubated with N-acetyl-cysteine in microsomes. And the precursor ions of possible cysteine-adducts were predicted based on covalent binding mechanisms to establish in-house database. Second, substrate-independent product ions produced from N-acetyl-cysteine moiety were selected. Third, multiple reaction monitoring scan was conducted to achieve sensitive screening for cysteine-targeting compounds. This strategy showed broad applicability, and covalent compounds with diverse structures were screened out, offering structural resources for covalent inhibitors development. Moreover, the screened compounds, norketamine and hydroxynorketamine, could modify synaptic transmission-related proteins in vivo, indicating their potential as covalent inhibitors. This experimental-based screening strategy provides a quick and reliable guidance for the design and discovery of covalent inhibitors.

Objective To analyze the trajectory categories of fatigue development in middle-aged and elderly stroke patients and explore its influencing factors. Methods A convenient sampling method was used to select 230 middle-aged and elderly stroke patients in the Luzhou People's Hospital from January 2021 to January 2023 as the research subjects. A self-compiled general information-questionnaire, the Fatigue Severity Scale (FSS), the Pittsburgh Sleep Quality Index (PSQI), and the Beck Depression Inventory (BDI) were used to investigate the sociodemographic and clinical data, fatigue, sleep quality, and depression status of patients at 2 days after admission and 3 and 6 months after discharge. The latent growth curve model was used to fit the categories and trajectories of fatigue development, and the unordered multinomial Logistic regression model was used to analyze the influencing factors of trajectory categories of fatigue development. Results The fatigue development trajectory of middle-aged and elderly stroke patients showed three potential categories, namely the low-level fatigue stability group (33.04%), the medium-level fatigue rapid aggravation group (42.17%), and the high-level fatigue slow aggravation group (24.79%). The results of unordered multinomial Logistic regression analysis showed that age, marital status, education level, disease severity, the Activity of Daily Living (ADL) score, PSQI score, and BDI score were the influencing factors of fatigue development trajectory in middle-aged and elderly stroke patients (all P < 0.05). Conclusion The fatigue development trajectory of middle-aged and elderly stroke patients is heterogeneous. Nurses should understand the evolution characteristics of fatigue in different patients and implement targeted management measures according to patients'symptoms to improve their health outcomes.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

The effect of vitamin D supplementation on individuals with autism spectrum disorder (ASD) is inconclusive. We aimed to conduct a meta-analysis of the available randomized controlled trials (RCTs) to explore whether vitamin D supplementation can improve core symptoms and coexisting conditions in children with ASD. Data were obtained by searching the PubMed, Embase, Web of Science, CINAHL and Cochrane Library databases up to February 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Using a random-effects model, mean differences with 95% confidence intervals (CIs) were calculated through a meta-analysis. There were eight RCTs with 266 children with ASD in the present review, among which six RCTs were included in the meta-analysis.Children who received vitamin D supplementation showed a significant improvement in stereotypical behavior scores (pooled mean difference (MD): −1.39; 95% CI: −2.7, −0.07; p = 0.04) with low heterogeneity (I2 = 34%), and there was a trend toward decreased total scores on the Social Responsiveness Scale (SRS) and Childhood Autism Rating Scale (CARS, p = 0.05); however, there were no other significant differences in the core symptoms of ASD and coexisting conditions between groups as measured by the Aberrant Behavior Checklist (ABC). Vitamin D supplementation appears to improve stereotypical behaviors but does not improve other core symptoms and coexisting conditions. Further randomized controlled trials with large sample sizes and individualized doses are needed.

Flagella are the main motility structure of Clostridioides difficile that affects the adhesion, colonization, and virulence of C. difficile in the human gastrointestinal tract. The FliL protein is a single transmembrane protein bound to the flagellar matrix. This study aimed to investigate the effect of the FliL encoding gene flagellar basal body-associated FliL family protein (fliL) on the phenotype of C. difficile. The fliL gene deletion mutant (ΔfliL) and its corresponding complementary strains (: : fliL) were constructed using allele-coupled exchange (ACE) and the standard molecular clone method. The differences in physiological properties such as growth profile, antibiotic sensitivity, pH resistance, motility, and spore production ability between the mutant and wild-type strains (CD630) were investigated. The ΔfliL mutant and the : : fliL complementary strain were successfully constructed. After comparing the phenotypes of strains CD630, ΔfliL, and : : fliL, the results showed that the growth rate and maximum biomass of ΔfliL mutant decreased than that of CD630. The ΔfliL mutant showed increased sensitivity to amoxicillin, ampicillin, and norfloxacin. Its sensitivity to kanamycin and tetracycline antibiotics decreased, and the antibiotic sensitivity partially returned to the level of CD630 strain in the : : fliL strain. Moreover, the motility was significantly reduced in the ΔfliL mutant. Interestingly, the motility of the : : fliL strain significantly increased even when compared to that of the CD630 strain. Furthermore, the pH tolerance of the ΔfliL mutant significantly increased or decreased at pH 5 or 9, respectively. Finally, the sporulation ability of ΔfliL mutant reduced considerably compared to the CD630 strain and recovered in the : : fliL strain. We conclude that the deletion of the fliL gene significantly reduced the swimming motility of C. difficile, suggesting that the fliL gene is essential for the motility of C. difficile. The fliL gene deletion significantly reduced spore production, cell growth rate, tolerance to different antibiotics, acidity, and alkalinity environments of C. difficile. These physiological characteristics are closely related to the survival advantage in the host intestine, which is correlated with its pathogenicity. Thus, we suggested that the function of the fliL gene is closely related to its motility, colonization, environmental tolerance, and spore production ability, which consequently affects the pathogenicity of C. difficile.

OBJECTIVE To investigate the association between the functional GLCCI1 gene rs37973 polymorphism and inhaled corticosteroids （ICSs） response in patients with asthma-chronic obstructive pulmonary disease overlap （ACO）. METHODS Totally 173 newly diagnosed ACO patients were recruited from Shanghai Pudong New Area People’s Hospital during April 1st， 2019 to December 31st， 2020. All patients were treated with Salmeterol fluticasone inhalation powder， twice a day， for 24 weeks. The genotype of rs37973 locus was determined， and lung function indicators [forced expiratory volume in one second （FEV1）， FEV1/forced vital capacity （FVC）， the percentage of FEV1 to expected value （FEV1%pred）]， and lung function improvement （ΔFEV1 and ΔFEV1%pred） were all detected. RESULTS Totally 111 patients completed the whole 24-week follow-up and lung function detection. Among them， there were 42 cases of AA genotype， 52 cases of AG genotype， and 17 cases of GG genotype. After 12， 24 weeks of treatment， lung function indexes of patients were significantly better than baseline lung function indexes before treatment （P＜0.05）. After 24 weeks of treatment， ACO patients with AA and AG genotypes showed significantly better lung function improvement than GG genotype， and ΔFEV1%pred of AA genotype was significantly better than AG genotype （P＜ 0.05）. After 12， 24 weeks of treatment， the improvement of lung function in patients with a smoking history ≤20 pack year was significantly better than those with a smoking history ＞20 pack year， and among patients with a smoking history ≤20 pack year， only AA genotype had significantly better FEV1%pred than AG genotype （P＜0.05）. After 12 weeks of treatment， among patients with a smoking history ＞20 pack year， the improvement of lung function in AA genotype and AG genotype was significantly better than GG genotype， and the FEV1%pred in AA genotype was significantly better than AG genotype （P＜0.05）. After 24 weeks of treatment， the improvement of lung function of AA genotype and AG genotype was significantly better than GG genotype （P＜0.05）. CONCLUSIONS GG genotype of GLCCI1 gene rs37973 locus is associated with the poor treatment response to ICSs in patients with ACO， especially in patients with smoking history ＞20 pack year.

Objective:To explore the application value of metagenomics sequencing in the etiological diagnosis of bacterial meningitis(BM) in children and improve the diagnosis and treatment effect of BM in children.Methods:All BM cases were collected from Jiangxi Provincial Children′s Hospital from February 1, 2018 to January 31, 2020.Meanwhile, such biological samples as blood and cerebrospinal fluid were collected for traditional etiological testing and metagenomics sequencing.The results of traditional etiological testing were regarded as the gold standard, and the specificity and sensitivity of metagenomics sequencing in the diagnosis of BM in children were confirmed.Results:A total of 45 cases were collected in this study, including 31 males and 14 females, with the age between (74.74 ± 58.67) months.Twenty-six cases were identified by metagenomics sequencing, with the positive rate being 57.78%.Among them, there were 8 cases of Streptococcus pneumoniae, 2 cases of Escherichia coli, 2 cases of Neisseria meningitidis, 2 cases of Staphylococcus, 2 cases of Salmonella, 2 cases of Mycobacterium multiplex, 1 case of Streptococcus intermedius, 1 case of Streptococcus pyogenes, 1 case of Streptococcus paris, 1 case of Streptococcus salivarius, 1 case of Haemophilus influenzae, 1 case of Pseudomonas aeruginosa, 1 case of Acinetobacter baumannii, and 1 case of Aspergillus.The traditional etiological positive rate was 17.78%, and the metagenomic next-generation sequencing (mNGS) positive rate was 57.78% ( P=0.014, kappa=0.273). As per the comparison results, the sensitivity, specificity, positive predictive value, negative predictive value, Youden index and misdiagnosis rate were 100.00%, 51.35%, 30.76%, 100.00%, 51.36%, 48.64% and 0, respectively. Conclusions:Metagenomics examination had high sensitivity, which can improve the etiological diagnosis rate of acute BM in children, especially in case of high clinical suspicion of infection.Therefore, metagenomics examination should be selected as early as possible when the etiology cannot be determined by traditional approaches.

OBJECTIVE: To investigate the complications of tourniquet in the clinical application of lower tibiofibular fracture. METHODS: From June 2018 to September 2019, 33 cases of closed lower tibiofibular fractures (AO type 43A) were treated with plates and screws and were divided into two groups according to whether pueumatic tourniquet was used:16 cases in the observation group, 13 males and 3 females, aged 18 to 69 (38.8±17.0) years, the operation time after injury was (6.9±1.7) days, and tourniquet was not used during operation. There were 17 cases in the control group, 13 males and 4 females, aged from 21 to 71 (43.8±12.4) years, the operation time after injury was (6.5±1.0) days, automatic pneumatic tourniquetwas routinely used in the operation. The operation time, blood loss, postoperative swelling, pain and other complications were compared between two groups. RESULTS: Total of 33 patients were followed up for an average of 15 months. There was no significant difference in operation time and blood loss between two groups ( CONCLUSION The fracture of lower tibiofibular segment is superficial and easy to be exposed and fixed during operation. In order to avoid tourniquet complications, it is not recommended to use air bag tourniquet routinely or minimize the application time of tourniquet.

Objective:To screen the differentially co-expressed genes in the mRNA expression profile of colon cancer by combined application of weighted gene co-expression network analysis(WGCNA) and differential gene expression analysis, and to analyze the relationship between differentially co-expressed genes and prognosis.Methods:The transcriptomics data of the cancer genome atlas (TCGA)-colon adenocarcinoma (COAD) dataset and chip expression profile data of GSE68468 dataset were downloaded from TCGA and gene expression omnibus (GEO) databases based on bioinformatics methods, and differentially expressed gene (DEG) and the most significantly related weighted gene modules between normal tissues and colon cancer tissues were screened. Then, the differentially co-expressed genes related to colon cancer were screened out according to the intersection of differential genes and weighted genes. A protein-protein interaction (PPI) network was constructed, and the top ten core differentially co-expressed genes according to the maximal clique centrality (MCC) score were screened out by MCC calculation method. The expression of core genes in normal tissues and colon cancer tissues were further verified by TCGA-COAD dataset. Kaplan-Meier survival analysis was used to investigate the correlation between core genes and overall survival time and disease-free survival time of patients. The survival-related differentially co-expressed genes were verified by immunohistochemical staining in human protein atlas (HPA) database.Results:A total of 3 481 DEG of the TCGA-COAD dataset and 7 275 DEG of the GSE68468 dataset were screened out, and totally 237 differentially co-expressed genes were obtained. Ten core differentially co-expressed genes were obtained by the MCC calculation method of the PPI network, which were chloride channel accessory 1 ( CLCA1), mitogen-activated protein kinase 3, glucagon ( GCG), solute carrier family 26 member 3 ( SLC26 A3), nuclear receptor subfamily 1 group H member 4 ( NR1 H4), fatty acid binding protein 1 ( FABP1), guanylate cyclase activator 2A ( GUCA2 A), uridine diphosphate glucuronosyltransferase family 2 member A3 ( UGT2 A3), carnitine palmitoyltransferase 2 ( CPT2) and membrane spanning 4-domains A12 ( MS4 A12). Compared with those of the normal tissues, CLCA1, GCG, SLC26 A3, NR1 H4, FABP1, GUCA2 A, UGT2 A3, CPT2 and MS4 A12 of colon cancer tissues of the TCGA-COAD dataset were all down-regulated (all P<0.05). Among them, the overall survival time and disease-free survival time of patients with colon cancer with high expression of CLCA1 were both longer than those with low expression (both P<0.05). The results of immunohistochemical staining also verified the accuracy of the results at the protein level. Conclusions:CLCA1 may play a key role in the development of colon cancer, and it can be used as a potential biomarker for further diagnosis and treatment.
