AIM To explore the clinical effects of Supplemented Buzhong Yiqi Decoction on patients with HP-positive chronic atrophic gastritis of Spleen-Stomach Deficiency Pattern.METHODS One hundred and thirty-two patients were randomly assigned into control group(66 cases)for 12-week intervention of conventional treatment,and observation group(66 cases)for 12-week intervention of both Supplemented Buzhong Yiqi Decoction and conventional treatment.The changes in clinical effects,HP clearance rate,miR-32,TGF-β1,IL-6,PGⅠ,PGⅡ,EGF,somatostatin,gastrin,motilin,gastroscopy pathological score and TCM symptom score were detected.RESULTS The observation group demonstrated higher total effective rate and HP clearance rate than the control group(P<0.05).After the treatment,the two groups displayed decreased miR-32,TGF-β1,IL-6,gastroscopy pathological score,TCM symptom score(P<0.05),and increased PGⅠ,PGⅡ,EGF,somatostatin,gastrin,motilin(P<0.05),especially for the observation group(P<0.05).CONCLUSION For the patients with HP-positive chronic atrophic gastritis of Spleen-Stomach Deficiency Pattern,Supplemented Buzhong Yiqi Decoction can alleviate inflammation,regulate gastrointestinal hormone levels,improve symptoms,and enhance efficacy.

Objective To investigate the efficacy and clinical results of total internal protection technique in anterior cru-ciate ligament reconstruction.Methods A total of 56 patients undergoing anterior cruciate ligament reconstruction treated from January 2018 to December 2019 were selected.According to the different surgical methods,they were divided into total inter-nal reconstruction group and standard bone tunnel group.There were 21 patients in the total internal reconstruction group,in-cluding 15 males and 6 females,aged from 20 to 48 with an average of(35.6±6.7)years old,and 35 patients in the standard tibial tunnel group,including 26 males and 9 females,aged 22 to 51 years old with an average of(33.7±9.6)years old.Preop-erative examination of Lachman test was positive,magnetic resonance indicated anterior cruciate ligament rupture.There were no significant differences between the two groups in age,sex,body mass index,time from injury to ACL reconstruction,com-bined meniscus injury and operation method,operation time,ligament diameter,ligament length and other general information.Postoperative evaluation included operation duration,length and diameter of transplanted tendon after braid.International Knee Documentation Committee(IKDC)score,Lysholm score,Tegner score and perioperative complications 2 years after surgery.Results Both groups were followed up,ranging from 24 to 30 months with an average of(26.9±3.4)months.Postoperative inci-sion healing was good,and no failure or joint infection occurred at the last follow-up.There was no statistically significant dif-ference between the two groups in IKDC score,Lysholm score and Tegner score before,1 year and 2 years after surgery.How-ever,IKDC score,Lysholm score and Tegner score at 1 year and 2 years after surgery.Conclusion The same postoperative function and stability of knee joint can be obtained by both the residual whole technique and the standardized reconstruction technique.In the residual whole group,only the semitendinosus muscle is taken,and the femoral thin muscle is retained,with greater tibial bone mass preserved,which is safe and effective in clinical practice.

Objective To analyze the differences in the expressions of the total and phosphorylated proteins in human colon cancer HCT116 cells after the knockout(KO)of retinoic acid-induced protein 16(RAI16)and explore the possible mechanism and related signaling pathways affecting its protein function in HCT116 cells.Methods HCT116 KO and WT cell proteins were collected and extracted,and the protein extraction efficiency was detected via a sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)experiment.After protein digestion,the peptides were labeled with TMT and analyzed via mass spectrometry.We used bioinformatics methods to analyze the identified differential proteins and differentially phosphory-lated proteins by using GO,KEGG,and STRING databases.Results The results of SDS-PAGE showed no evident protein degradation.In addition,some key bands were significantly different between the experi-mental and control groups.A total of 147 up-regulated and 230 down-regulated differential proteins were screened in accordance with the conditions of Foldchange≥1.5 or Foldchange≤1/1.5 and P<0.05.Meanwhile,106 up-regulated and 217 down-regulated phosphorylation sites were screened.GO enrichment analysis revealed that the differential proteins were mainly enriched in the composition of nucleoplasm,nucleus and cytoplasm,RNA binding,cadherin and chromatin,DNA repair,RNA splicing,and positive regulation of DNA as template transcription.The results of KEGG enrichment indicated that the differential proteins were mainly enriched in nucleocytoplasmic transport,spliceosomes,cell cycle,cell-cell tight junctions,viral carcinogenesis,microRNAs in cancer,etc.The protein interaction network mainly focused on DDX17,NCL,EEF2,CDK1,SSRP1,and SMARCC1.The statistical findings unveiled the up-regulated changes in the two omics of SKP1,ORC1,and BAD and the down-regulated changes in RBL1,RB1,CDK1,CDC6,MCM4,TFDP1,CHD4,and SNW1.Moreover,the phosphorylation differences were more significant than the protein differences.Conclusion RAI16 plays the possible crucial role in multiple biological functions and signaling pathways through key proteins,such as SKP1,ORC1,RB1,and CDK1,which affect the cell cycle and thereby the occurrence and development of cancer.

Objective To investigate the morphological changes in the upper airway after bimaxillary surgery in patients with skeletal Class Ⅲ malocclusion and the relationship between jaw movement and airway changes using CBCT.Methods This study involved 44 individuals(21 males and 23 females)receiving Class Ⅲ bimaxillary surgery.Preoperative and 3-6-month postoperative CBCT data were examined using Dophin3D 11.95 software.The alterations before and after upper airway surgery were analysed using paired t-test and non-parametric Wilcoxon rank sum test.The association between airway alterations and jaw movement was examined using Pearson's correlation coefficient.Results Patients who underwent Class Ⅲ bimaxillary surgery had significantly reduced upper airway volume,sagittal cross-sectional area,and minimum cross-sectional area(P＜0.01).A correlation exists between oropharyngeal volume change and point B change(P＜0.05).When B point recession was＞7 mm,the decrease in upper airway volume increased significantly(P＜0.01),as did the risk of minimum cross-sectional area of the patient's airway(P＜0.01).Conclusion ClassⅢbimaxillary surgery re-duces upper airway capacity.Postoperative reduction in upper airway capacity coincides with mandibular recession.Mandibular reces-sion(＞7 mm)may reduce postoperative upper airway capacity and increase the risk of OSAHS.Patients at risk of upper airway stenosis should have their protocol modified to reduce airway risk.

This study analyzed and compared the epidemiological characteristics of foodborne listeriosis in the United States and China,to provide evidence for optimizing the listeriosis surveillance program in China.Descriptive statistical analysis was performed on the listeriosis monitoring data from 2009 to 2021 registered in the FDOSS system and the attribution estimates of Listeria monocytogenes(L.monocytogenes)from 2013 to 2021 published by IFSAC.Sporadic and outbreak data on listeriosis in China from the CNKI,Wanfang Medical,and CQVIP databases were collected.From 2009 to 2021,a total of 1 037 listeriosis cases were reported in the United States,including 902 hospitalizations and 165 deaths.The peak of cases caused by Lm con-taminated food was in July.The number of cases,hospitalizations,and deaths accounted for 18.4％(191/1 037),20.5％(185/902),and 22.4％(37/165)of the total,respectively.Most listeriosis outbreaks were attributed to three food groups:dairy products,vegetable crops,and fruits,with attribution percentages ranging from 73.8％to 89.6％.The overall incidence of list-eriosis in China was not high:619 cases were reported from 2009 to 2021,and only 177 cases were recorded in detailed inci-dence years;the maximum number of cases in 2018 was 26.A total of 220 cases were reported with detailed onset months;the highest number of cases in April was 30.Data on listeriosis cases in China are incomplete and sporadic,and only seven cases have been successfully traced to food.Listeriosis surveillance systems in the United States are relatively complete,and there are more foodborne outbreaks.Dairy products,vegetable row crops,and fruits are the most likely causes of disease outbreaks.Although only sporadic cases have been reported in China,China should take actions such as gradually improving multi-department coop-eration mechanisms,achieving data sharing and deepening data mining,and accelerating progress in the detection technology of food-borne pathogenic microorganisms,to ensure food safety and public health.

Objective:To identify the genetic mutation of coagulation factor Ⅶ(F7)gene in a pedigree with coagulation factor Ⅶ(FⅦ)deficiency and explore the molecular pathogenesis.Methods:The prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),D-dimer(DD),fibrin degradation products(FDP)and coagulation factor Ⅶ activity(FⅧ:C)of the proband and her family members were detected by Sysmex-CS5100 analyzer.All exons and exon-intron boundaries of the F7 gene were amplified by PCR followed by direct sequencing.The detected mutation was confirmed by reverse sequencing.The ClustalW software was used to analyze the conservatism of the mutant site.Pathogenicity of the mutation was assessed with Mutation Taster and PolyPhen-2 online bioinformatics software.Structure of the mutant protein was analyzed using Swiss-PdbViewer software.Results:The results of routine coagulation tests showed that PT of the proband was markedly extended to 42.5 s,and her FⅦ:C significantly reduced to 2％.The FⅦ:C of her grandmother,mother and sister had slightly reduced to 49％,51％,and 42％,respectively.These coagulant parameters of her father were within the normal range.Genetic analysis reveled a heterozygous G＞A change at cDNA 646 in exon 6 of F7 gene in the proband,resulting in a replacement of glycine at 156 of FⅦ catalytic region with serine(p.Gly156Ser).The sequencing results of other exons and exon-intron boundaries of her F7 gene were normal.The proband's grandmother,mother and sister were all the carriers of this missense mutation except her father.Bioinformatics analysis showed that the p.Gly156Ser mutation caused polarity change of the amino acid at this site and formation of side chains,leading to increase of protein instability,which may affect catalytic activity of structural domain.Meanwhile,both Mutation Taster and PolyPhen-2 online bioinformatics software also predicted the pathogenicity of this missense mutation with high scores.Conclusion:The heterozygous p.Gly 156Ser mutation is the direct cause of the reduced FⅦ in this proband.

Methamphetamine abuse is a major public health problem in the world,and in recent years,methamphetamine is also the most abused synthetic drug in China.The neurotoxic or addiction mechanism of methamphetamine has not been fully clarified,and there is still a lack of specific withdrawal methods and drugs for methamphetamine abuse.Mitochondria are not on-ly the organelles to which methamphetamine directly produces toxic effects,but also participate in regulating the neurotoxic damage process of methamphetamine.Mitochondrial quality is the regulatory basis for maintaining mitochondrial homeostasis and is regulated by three main mechanisms,which are mitochon-drial biogenesis,mitochondrial dynamic,and mitophagy.This review summarizes the research progress of mitochondrial quality control in methamphetamine-induced neurotoxicity,which may provide theoretical support for further research on the mechanism of methamphetamine neurotoxicity and development the mito-chondria-targeting drugs.

Objective:To evaluate the diagnostic performance of the Prostate Imaging Reporting and Data System version 2.1(PI-RADS v2.1)for clinically significant prostate cancer(CSPCa)in the peripheral zone(PZ),transitional zone(TZ)and multiple zones(MZs).Methods:We retrospectively studied the clinical data on 108 patients undergoing multiparametric magnetic resonance imaging(mpMRI)and transperineal prostate biopsy in our hospital from January 2021 to January 2023.Using PI-RADS v2.1,we ex-amined the MR images of the patients with suspected PCa,compared the PI-RADS v2.1 scores with the results of prostate biopsy,and analyzed the correlation of the PI-RADS v2.1 scores with CSPCa.We calculated the area under the receiver operating characteristic(ROC)curve(AUC),and described the diagnostic performance of PI-RADS v2.1 for CSPCa in the PZ,TZ and MZs.Results:Transperineal prostate puncture biopsy was successfully completed in all the patients,which revealed 66(61.11％)cases of CSPCa with Gleason score(GS)7-10.Suspected CSPCa was observed in 45(95.74％)of the 47 PZ lesions,8(47.06％)of the 17 TZ le-sions,and 40(90.91％)of the 44 MZ lesions.The PZ,TZ and MZ lesions diagnosed by PI-RADS v2.1 were significantly correlated with CSPCa(r=0.492,P＜0.001).The AUCs of PI-RADS v2.1 for PZ,TZ and MZs were 0.644,0.732 and 0.811,with specificities of 66.8％,57.6％and 62.1％,and sensitivities of 57.2％,78.4％and 93.2％,respectively.The negative predictive values were 46.5％,85.7％and 79.2％,and the positive predictive values 76.2％,43.4％and 84.8％,respectively.Conclusion:The PI-RADS v2.1 score has a high diagnostic value for CSPCa in the PZ,TZ and MZs,with the best performance for that in the MZs.

Objective: To compare the effects of the China Children's Asthma Action Plan (CCAAP)-based remote joint management model with traditional management model on the control of childhood asthma. Methods: A retrospective cohort study was conducted to analyze the general data and asthma control assessment data of 219 children with asthma who attended the respiratory department of Guangzhou Women's and Children's Medical Center from April 2021 to October 2021 and were followed up for 1 year or more. According to the follow-up management model, the CCAAP-based remote joint management model was used in the observation group and the traditional management model was used in the control group, and the propensity score matching method was applied to match the data of children in the two management models for comparison. Paired-samples t-test, Wilcoxon signed-rank test, McNemar χ²-test or χ²-test or nonparametric tests were used to compare the general data and asthma control assessment data between the two matched groups of children. Results: Among 219 children with asthma, 145 were male and 74 were female, aged at consultation (7.2±2.4) years. There were 147 cases in the observation group and 72 cases in the control group, and 27 cases in each of the observation and control groups were successfully matched. The number of asthma exacerbation aura, acute exacerbations, and emergency room visits or hospitalizations for asthma exacerbations were lower in the observation group than in the control group after pairing (1 (0, 2) vs. 3 (1, 5) times, 0 (0,0) vs. 0 (0, 1) times, 0 (0,0) vs. 1 (0, 1) times, Z=-3.42, -2.58, -3.17, all P<0.05). The use of peak flowmeters was higher in children aged 5 years and older in the observation group than in the control group after pairing (100% (22/22) vs. 13% (3/23), χ²=54.00,P<0.001). The ratio of actual to predicted 1st second expiratory volume of force after follow-up in the observation group after pairing was higher than that before follow-up in the observation group and after follow-up in the control group ((95±11)% vs. (85±10)%, (95±11)% vs. (88±11)%, t=-3.40, 2.25, all P<0.05). The rate of complete asthma control after follow-up was higher in both the observation and control groups after pairing than before follow-up for 12 months in both groups (93% (25/27) vs. 41% (11/27), 52% (14/27) vs. 41% (11/27), H=56.19, 45.37, both P<0.001), and the rate of complete control of asthma in children in the observation group was higher than that in the control group at 3 and 12 months of follow-up management (56% (15/27) vs. 25% (5/20), 93% (25/27) vs. 52% (14/27), χ²=47.00, 54.00, both P<0.001). The number of offline follow-up visits, inhaled hormone medication adherence scores, and caregiver's asthma perception questionnaire scores were higher in the observation group than in the control group after pairing (6 (4, 8) vs. 4 (2,5), (4.8±0.3) vs. (4.0±0.6) score, (19.3±2.6) vs. (15.2±2.7) score, Z=6.58, t=6.57, 5.61, all P<0.05), and the children in the observation group had lower school absences, caregiver absences, asthma attack visit costs, and caregiver PTSD scores than the control group (0 (0,0) vs.3 (0, 15) d, 0 (0,0) vs. 3 (0, 10) d, 1 100 (0, 3 700) vs. 5 000 (1 000, 10 000) yuan, 1.3 (1.1, 1.9) vs. 2.0 (1.2, 2.7) score, Z=-2.89, -2.30, 2.74, 2.73, all P<0.05). Conclusion: The CCAAP-based joint management model of asthma control is superior to the traditional management model in the following aspects: it can effectively improve asthma control, self-monitoring, and lung function in children; it can improve treatment adherence and caregivers' asthma awareness; and it can reduce the duration of absenteeism from school, the cost of asthma exacerbation visits, and caregiver's negative psychology.
