Objective:To analyze the clinical characteristics and prognosis of children with hypodiploid B-cell precursor acute lymphoblastic leukemia(BCP-ALL).Methods:The clinical data of 1 287 children with BCP-ALL admitted to five hospital in Fujian province from April 2011 to December 2020 were retrospectively analyzed.According to the results of chromosome karyotype,all the patients were grouped into hypodiploid subgroup and non-hypodiploid subgroup.The clinical characteristics,early treatment response[minimal residual disease(MRD)on middle stage of induction chemotherapy and end of induction chemotherapy]and long-term efficacy[overall survival(OS)and event-free survival(EFS)]were compared.The prognostic factors of hypodiploid BCP-ALL were further explored.Results:Among 1 287 BCP-ALL patients,28 patients(2.2％)were hypodiploid BCP-ALL.The proportion of patients with white blood cell count(WBC)≥50 x 109/L in the hypodiploid subgroup was significantly higher than that in the non-hypodiploid subgroup(P=0.004),while there was no statistically significant difference in gender ratio,age group at initial diagnosis,and early treatment response between the two groups(all P＞0.05).The 5-year EFS and OS rate of the hypodiploid subgroup were 75.0％(95％CI:66.8％-83.2％)and 77.8％(95％CI:69.8％-85.8％),respectively,which were lower than those of non-hypodiploid subgroup[EFS:79.6％(95％CI:78.4％-80.8％);OS:86.4％(95％CI:85.4％-87.5％)],but the difference was not statistically significant(all P＞0.05).Further subgroup analysis by risk stratification showed that the 5-year EFS and OS rates of the hypodiploid subgroup were significantly lower than those in the low-risk(LR)group[LR group EFS:91.4％(95％CI:88.4％-93.6％),P＜0.001;OS:94.7％(95％CI:92.1％-96.4％),P＜0.001];it was similar to that of BCP-ALL children stratified into intermediate-risk(IR)excluding hypodiploid[IR group EFS:79.4％(95％CI:74.9％-83.2％),P=0.343;OS:87.3％(95％CI:83.6％-90.2％),P=0.111];while was higher than that of EFS in HR group,but the difference was not statistically significant[HR group EFS:58.7％(95％CI:52.6％-64.8％),P=0.178.OS:69.9％(95％CI:63.5％-75.4％),P=0.417].Univariate analysis showed that gender,age,white blood cell count,and MRD on middle stage of induction chemotherapy had no significant impact on OS and EFS;chromosome count＜40 was a risk factor for lower OS(P=0.026),but has no significant effect on EFS;MRD≥0.01％after induction therapy was a risk factor for lower OS and EFS(P=0.002,and 0.001,respectively).Conclusion:Children with hypodiploid BCP-ALL have an intermediate prognosis,and MRD ≥0.01％after induction chemotherapy may be a risk factors for poor prognosis.

Purpose To investigate the effect of MYD88 gene overexpression on the proliferation and apoptosis of human diffuse large B cell lymphoma(DLBCL)cells,and to prelimi-narily explore the mechanism of MYD88 gene action.Methods PEGFP-C2-MYD88 overexpressing MYD88 L265P gene was transfected into DLBCL cells by plasmid transfection.The exper-iment was divided into blank control group,negative control group and MYD88 L265P overexpression group.The fluores-cence expression of MYD88 L265P after overexpression was ob-served under inverted fluorescence microscope.RT-PCR and Western blot were used to detect the mRNA and protein expres-sion of MYD88 L265P,IRAK4,NF-κB and BCL2 in DLBCL cells before and after overexpression of MYD88 L265.CCK8 method was used to detect DLBCL cells proliferation and Ho-echst staining was used to detect DLBCL cells apoptosis.Re-sults After overexpression of MYD88 L265P,compared with the blank control group(0.670 4±0.017 5)and the negative control group(0.715 3±0.019 6),the MYD88L265P overex-pression group(1.157 2±0.010 2)increased significantly,with statistical significance(all P＜0.05).After overexpression of MYD88 L265P,compared with the blank control group(0.69 ±0.04)and the negative control group(0.81±0.07),the MYD88L265P overexpression group(0.48±0.05)was signifi-cantly decreased,with statistical significance(all P＜0.05).After overexpression of MYD88 L265P,compared with the blank control group(mRNA:1.0158±0.0115,0.987 3±0.010 2,1.007 6±0.015 3,protein:0.183 4±0.058 9,0.096 8± 0.015 7,0.147 5±0.0418)and negative control group(mR-NA:0.9132±0.0098,1.0032±0.0156,0.9327± 0.011 2,protein:0.187 9±0.042 3,0.088 9±0.0513,0.134 8±0.050 1),the mRNA(3.243 2±0.013 6,2.976 6 ±0.0213,1.585 9±0.019 8)and protein expressions(0.452 7±0.052 4,0.218 9±0.047 5,0.301 4±0.059 8)of IRAK4,NF-κB and anti-apoptosis protein BCL2 in MYD88L265P overexpression group were significantly increased,which was statistically significant(all P＜0.05).Conclusion After overexpression of MYD88 L265P,the apoptosis rate of DLBCL cells decreased and the cell proliferation rate increased.The mechanism may be related to the mutation of MYD88 L265P gene,activation and amplification of NF-κB pathway,and pro-motion of the overexpression of antiapoptotic protein BCL2.

Objective:To explore the decision-making experience of patients undergoing abdominoplasty in our country.Methods:A semi-structured interview was conducted with patients suffering from postpartum abdominal wall laxity who were treated at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June to August 2023. The data were sort and analyzed using the Clolaizzi 7-step analysis method for thematic description.Results:A total of 15 patients, aged 29-53 years, were included in the study. 11 had a college education or higher, while 4 had less than a college education.Thirteen were married and two were divorced. According to the interview data, four themes were extracted: (1) negative perceptual experiences; (2) decision-making dilemmas; (3) peer support; (4) a physician-led decision-making model. According to the interview, the main decision-making dilemma faced by patients with postpartum abdominal wall laxity was lack of information and family support, and the support they get was mostly from information exchange among patients, and they had insufficient cognition of surgical knowledge, improvement degree and risk, and low participation in clinical decision making.Conclusion:Patients with postpartum abdominal wall laxity in China have an urgent psychological need for abdominoplasty, but there are many factors that have adverse effects on their decision-making experience.

Objective To investigate the epidemiological characteristics and molecular transmission mechanism of the colistin resistance gene mcr-1 in food animal-derived Escherichia coli in Hanzhong, Shaanxi Province, and to grasp the prevalence of mcr-1 positive Escherichia coli in Hanzhong, in order to offer the empirical evidence for the prevention and management of disseminating the mcr-1 colistin resistance gene in both community and hospital settings. Methods From November 2019 to May 2020, frozen whole chicken carcasses and frozen raw ground pork were randomly sampled from seven major supermarkets in Hanzhong, Shaanxi Province, for the isolation and identification of Escherichia coli. The mcr-1 gene was detected using PCR analysis, and the drug susceptibility of mcr-1-positive strains was assessed using the broth dilution method. Whole genome sequencing, S1-pulsed field gel electrophoresis (PFGE), and Southern blot were used to locate the mcr-1 gene. Results Out of 159 samples randomly collected from seven different supermarkets, 77 Escherichia coli strains were isolated, and 11 strains carrying the mcr-1 gene were detected, with a positive rate of 14.29%. All 11 mcr-1-positive strains were multidrug-resistant, with a minimum inhibitory concentration (MIC) for colistin ≥2 mg/L (11/11). They exhibited a 100.00% resistance rate to ampicillin, streptomycin, tetracycline, and chloramphenicol (11/11), and all produced extended-spectrum beta-lactamases (ESBLs). The strains exhibited susceptibility to carbapenems and cefoxitin but had a 90.91% resistance rate to quinolones ciprofloxacin and levofloxacin. The mcr-1 gene was located on plasmids in 10 of the mcr-1-positive strains, with plasmid sizes approximately 60 kb and 220 kb. The 11 mcr-1-positive Escherichia coli strains belonged to 9 different sequence types (STs), including one previously unidentified ST. Besides carrying the colistin resistance gene mcr-1, all isolates possessed at least one ESBLs gene, predominantly blaCTX-M-55 (8/11, 72.73%). The plasmid types harboring mcr-1 were predominantly IncI2 (5/11, 45.45%) and IncHI2 (5/11, 45.45%), with one strain having mcr-1 located on the chromosome. Conclusions The mcr-1-positive Escherichia coli detected in this study are all multidrug-resistant and produce ESBLs, predominantly blaCTX-M-55. The mcr-1 gene can be transmitted through plasmid and chromosome.

Purpose: Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict adverse survival outcomes among patients with colorectal cancer (CRC). This study evaluates the prognostic value of NLR among patients with obstructing CRC who successfully underwent stenting before curative surgery. Methods: We retrospectively reviewed patients who underwent stenting before surgery. Patient demographics, tumor characteristics, perioperative outcomes, recurrence-free survival (RFS), and overall survival (OS) were analyzed. NLR was calculated from the differential white blood cell counts at least 4 days after successful stenting, before elective surgery. Optimal cutoff to dichotomize NLR was obtained by maximizing log-rank test statistic with recursive partitioning of KaplanMeier RFS and OS curves. The optimal cutoff for high NLR was ≥ 5 at presentation before stenting, and ≥ 4 after stenting. Results: Fifty-seven patients with localized obstructing CRC underwent successful endoscopic stenting before curative surgery. High NLR was associated with lymphovascular invasion (P = 0.006) and apical lymph node involvement (P = 0.034). Major perioperative complication(s) (hazard ratio [HR], 11.34; 95% confidence interval [CI], 2.49 to 51.56; P < 0.01) and high NLR (HR, 3.69; 95% CI, 1.46 to 9.35; P < 0.01) negatively impacted OS on univariate and multivariate analyses. High NLR negatively impacted RFS on univariate analysis (HR, 2.91; 95% CI, 1.29 to 6.60; P = 0.01). Conclusion NLR of ≥ 4 after stenting is an independent prognostic factor among patients with obstructing localized CRC who are successfully decompressed by endoscopic stenting before curative surgery.

Objective:To analyze the compatibility rules of prescriptions containing Forsythiae Fructus based on data mining and explore the anti-inflammatory mechanism of Forsythiae Fructus based on network pharmacology，so as to provide reference for the rational clinical application of Forsythiae Fructus and the development of health foods and new Chinese medicines. Method:The prescriptions containing Forsythiae Fructus in the Dictionary of Traditional Chinese Medicine Prescriptions were collected，based on which a clinical prescription database was constructed. The Chinese herbs combined with Forsythiae Fructus and the corresponding indications were subjected to frequency statistics，association rule analysis，and complex network analysis using SPSS Statistics 26，IBM SPSS Modeler 18.0，and Gephi 9.2. The active components and targets of Forsythiae Fructus for anti-inflammation were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP），BATMAN-TCM，and SEA，and the targets related to anti-inflammation from GeneCards，Online Mendelian Inheritance in Man （OMIM），CTD，and GenCLiP3. Following the analysis of protein-protein interactions （PPI） with STRING，a PPI network was constructed. The enrichment analysis was performed using Metascape，and the active component-anti-inflammation target-signaling pathway network of Forsythiae Fructus was constructed by Cytoscape 3.8.2. Result:According to the inclusion and exclusion criteria，2 245 prescriptions containing Forsythiae Fructus were harvested，involving 512 Chinese herbs，with a total usage frequency of 27 314. The Chinese herbs that were most frequently combined with Forsythiae Fructus （>800 times） were Glycyrrhizae Radix et Rhizoma （1 483 times），Scutellariae Radix （964 times），and Angelicae Sinensis Radix （842 times）. Hence，the herbal pairs "Forsythiae Fructus-Scutellariae Radix" and "Forsythiae Fructus-Angelicae Sinensis Radix" were further explored. The prescriptions containing Forsythiae Fructus could be utilized for the treatment of 29 kinds of diseases，and three representative disease categories including "carbuncle，gangrene，sores and ulcers"，"ophthalmic diseases and syndromes" and "epidemic diseases" are selected for data mining. There were 19 association rules obtained with "Forsythiae Fructus-Glycyrrhizae Radix et Rhizoma-Lonicerae Japonicae Flos-Angelicae Sinensis Radix" as the core herb combination for "carbuncle，gangrene，sores and ulcers". The clustering analysis revealed one multi-herb clustering group，four herbal pairs，and single herb Lonicerae Japonicae Flos，the complex network analysis four herbal modules，and the factor analysis six common factors. There were 23 association rules obtained with "Forsythiae Fructus-Glycyrrhizae Radix et Rhizoma-Scutellariae Radix-Angelicae Sinensis Radix" as the core herb combination for "ophthalmic diseases and syndromes". The clustering analysis revealed two multi-herb clustering groups and four herbal pairs，the complex network analysis four herbal modules，and the factor analysis five common factors. There were 28 association rules obtained with "Forsythiae Fructus-Glycyrrhizae Radix et Rhizoma-Menthae Haplocalycis Herba-Lonicerae Japonicae Flos" as the core herb combination for "epidemic diseases". The clustering analysis revealed three multi-herb clustering groups，one herbal pair，and two single herbs Forsythiae Fructus and Glycyrrhizae Radix et Rhizoma，the complex network analysis four herbal modules，and the factor analysis five common factors. As demonstrated by network pharmacology-based analysis，the core anti-inflammation components of Forsythiae Fructus were quercetin，luteolin，and kaempferol，and the core targets were phosphoinositide-3-kinase regulatory subunit 1 （PIK3R1），protein kinase B 1 （Akt1），and epidermal growth factor receptor（EGFR）. The biological pathways were mainly concentrated in proteoglycans in cancer，pathways in cancer，and PI3K/Akt signaling pathway，with such functions as inhibition of transcription factors，regulation of enzyme activity，and inflammation-related gene expression involved. Conclusion:This study employed a variety of data mining techniques to objectively，intuitively，and scientifically uncover the compatibility rules of Forsythiae Fructus in the treatment of high-frequency diseases. It has been found that Forsythiae Fructus is often combined with heat-clearing herbs，tonifying herbs，exterior-releasing herbs，and blood-activating and stasis-resolving herbs for diverse diseases and syndromes. Under the premise of clearing heat and removing toxin，reinforcing healthy Qi and dredging stagnation are also emphasized. According to the degree of internal heat exuberance，the heat-clearing herbs with different merits are combined. This study has revealed the unique advantages of Forsythiae Fructus in the treatment of specific diseases and syndromes as well as its multi-component，multi-target，and multi-pathway mechanisms in anti-inflammation，breaking through the limitations in modern clinical and experimental research of Forsythiae Fructus. These findings are of great significance for guiding the rational clinical application of Forsythiae Fructus and the development of health foods and new Chinese medicines，thus better accelerating the development of Chinese medicine health industry.

Introduction: A cross-sectional study is used to evaluate the lifestyle factors associated with cardiovascular disease (CVD) risk among healthcare workers in tertiary hospitals in Sarawak, Malaysia. Methods: A questionnaire-based survey using the Simple Lifestyle Indicator Questionnaire (SLIQ) was administered to, and anthropometric measurements were collected from, 494 healthcare workers. Results: Te mean age of the subjects was 32.4±8.4, with a range of 19 to 59 years. Te subjects were from the allied health (45.5%), management and professional (25.1%) and executive (29.4%) felds. Overall, 47.4% of the subjects were of normal weight, 30.2% were overweight, 17.2% were obese and 5.2% were underweight. Te mean number of working hours per week for the subjects was 47.6±14.0 with the highest working hours found among the management and professional group, followed by the executive and allied health groups. Overall, 39.7% of the healthcare workers worked ofce hours, 36.6% worked within the shift system, 20.9% worked ofce hours and were on-call and the remaining 2.8% worked a mixture of ofce hours and shifts. Based on the SLIQ score, 58.1% were classifed as at intermediate risk for CVD, 38.5% were in the healthy category and 3.4% were in the unhealthy category. Factors associated with a healthier lifestyle were being female (Odds Ratio [OR]= 12.1; CI= 3.2- 46.4), professional (mean score= 6.70), in the allied health group (mean score=7.33) and in the normal BMI group (OR= 9.3, CI= 1.8- 47.0). Conclusion: In our study, healthcare workers had an intermediate risk of developing CVD in the future. Tus, there is a need to intervene in the lifestyle factors contributing to CVD.
