This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

ObjectiveTo investigate the effects of atorvastatin （ATV） on the proliferation and differentiation of rat bone marrow mesenchymal stem cells （BMSCs）， periodontal ligament stem cells （PDLSCs）， and dental pulp stem cells （DPSCs） in vitro， and to validate the regulatory effect of ATV on periodontal bone formation and tooth movement using a rat orthodontic tooth movement （OTM） model. MethodsThe effects of ATV on the proliferation and osteogenic/odontogenic differentiation of rat BMSCs， PDLSCs， and DPSCs were assessed in vitro. CCK-8 assay was used to detect the proliferation of the three types of cells. Alkaline phosphatase （ALP） staining and Alizarin Red staining were employed to evaluate osteogenic differentiation capacity. Western blot was used to detect the expression of osteogenesis-related proteins ［collagen type I （COL-I）， Runt-related transcription factor 2 （Runx2）， bone morphogenetic protein-2 （BMP-2）， osteocalcin （OCN）］ and the odontogenesis-related protein dentin sialophosphoprotein （DSPP） in BMSCs， PDLSCs and DPSCs. An OTM rat model was established， with rats randomly assigned to an ATV gavage group and a control group. The ATV gavage group received daily oral administration of ATV at a dose of 20 mg/kg， while the control group received an equal volume of solvent by gavage. Tooth movement distance was measured via Micro-CT on days 7， 14， and 21. Histomorphology of periodontal tissues was observed using Hematoxylin and Eosin （HE） staining and Masson staining. The gene and protein expression levels of osteogenic markers （BMP-2， Runx2， OCN） on the tension side of the first molar were detected by qRT-PCR and immunohistochemistry， respectively. ResultsATV at concentrations of 1×10⁻⁶ mol/L and 1×10⁻⁷ mol/L significantly promoted the proliferation and osteogenic/odontogenic differentiation of BMSCs， PDLSCs， and DPSCs， manifested as enhanced ALP activity， increased mineralized nodule formation， and up-regulated expression of osteogenic/odontogenic proteins COL-I， Runx2， BMP-2， OCN， and DSPP （P<0.001）. In the OTM model， compared with the control group， the ATV gavage group showed a significant reduction in tooth movement distance （P<0.05）， enhanced osteogenic activity in periodontal tissues， and significantly increased gene （P<0.001） and protein （P<0.05） expression of BMP-2， Runx2， and OCN on the tension side of the first molar. ConclusionATV enhances periodontal osteogenesis by promoting osteogenic/dentinogenic differentiation， thus inhibiting tooth movement.

ObjectiveZheng’s San Qi San (ZSQS) power, a classic traditional Chinese medicine (TCM) formula, is used for treating soft tissue injuries involving muscles, tendons, and ligaments. However, its underlying therapeutic mechanisms remain unclear. This study aimed to screen and identify pharmaceutically active ingredients and their candidate biomolecule targets, and further elucidate the molecular mechanism of ZSQS in the treatment of skeletal muscle injury. MethodsNetwork pharmacology was employed to construct “ZSQS-component-target”, “protein-protein interaction (PPI)” and “active ingredient-core protein-pathway” networks to predict the key active ingredients and potential core targets of ZSQS for skeletal muscle injury. The predicted results were then validated via microarray data from the GEO database. Molecular docking was then performed to assess the binding ability between the screened active ingredients of ZSQS and the candidate core targets. Moreover, liquid chromatography-mass spectrometry (LC-MS) was used for qualitative and quantitative analysis to verify the active components of the drug and ZSQS serum. Finally, an animal model of eccentric exercise-induced skeletal muscle injury and a myotube cell model of oxidative stress-induced injury were established to validate the effects of ZSQS and its interventional effects on the biological functions of critical targets, thereby demonstrating the potential therapeutic mechanism of ZSQS. ResultsAmong the 111 active components identified in ZSQS and their corresponding 204 targets related to the skeletal muscle injury repair process, 14 core targets (including AKT1) and 4 core active components (quercetin, luteolin, kaempferol, and β‑sitosterol) were screened out, while the corresponding metabolites of quercetin, luteolin and kaempferol were detected in the ZSQS serum. Among these targets, 5 candidate genes (IL-6, CASP3, HIF1A, STAT3, and JUN) overlapped with the differential expression screening results with GEO data, and IL-6 was confirmed to be enriched in the PI3K/AKT pathway. Combined with the prediction results of the AKT expression levels, these findings suggest that the phosphorylation level of AKT1 plays a core role in the therapeutic mechanism of ZSQS. Molecular docking analysis further revealed that the PH domain of AKT1 had high binding energy with all 4 core active components, as verified by LC-MS. Finally, animal model studies have shown the promoting effect of ZSQS administration on skeletal muscle injury repair and its possible antioxidant damage mechanism. Cell model studies further demonstrated that ZSQS-containing serum, core active ingredient combination therapy, and quercetin monomer could increase the phosphorylation level of AKT, promote the nuclear translocation of Nrf2, upregulate the expression of downstream antioxidant enzymes (SOD, GPx, and GR), and inhibit the expression of inflammatory factors (IL-6 and TNF-α), thereby alleviating oxidative stress and the inflammatory response. ConclusionZSQS alleviates skeletal muscle injury mainly by activating the AKT/Nrf2 signaling pathway, enhancing cellular antioxidant and anti-inflammatory capabilities. The results of this study provide a scientific basis for the clinical application and modernized development of ZSQS.

Objective: To investigate the genetic basis of RhD-negative phenotype in the blood donor population of Nantong City. Methods: RHD genotyping was performed on 386 randomly selected RhD-negative donor samples (from a total of 676 RhD-negative donors identified between January 20, 2023, and June 28, 2024) using polymerase chain reaction (PCR), and the inconclusive results were confirmed by nucleotide sequencing. Results: Ten RHD allele types were identified: The complete deletion variant RHD 01N.01 was predominant (64.25%, 248/386); followed by RHD 01EL.01 (19.69%, 76/386). RHD 01N.03, RHD 01N.04, RHD 01N.16 and RHD 01EL.32 were frequently observed., RHD 01EL.02, RHD 01EL.08, RHD 01EL.37 and RHD 01N.25 were rare, and two exon deletion variants remained uncharacterized. The phenotypic distribution of RhD-negative blood donors was ccee (55.44%)>Ccee(31.09%)>ccEe(5.96%)>CCee(5.44%)>CcEe(1.81%)>CcEE(0.26%), and the antigen distribution trend was e(99.74%)>c(94.56%)>C(38.60%)>E(8.03%). A correlation was observed between RHD genotypes and RhCE phenotypes. Conclusion: The Nantong blood donor population exhibits unique RHD gene polymorphisms. Integrating RhCE serological phenotyping with RHD genotyping is essential for ensuring transfusion safety.

Objective To explore the relationship of metabolic comorbidities and insulin resistance(IR)with chronic kidney disease(CKD)among elderly individuals undergoing health exam.Methods A cross-sectional observational study was conducted on 8358 older adults who took health exam in Chinese PLA General Hospital between December 2009 and May 2021.According to the guidelines for CKD diagnostic criteria,they were divided into CKD group(983 cases)and non-CKD(7375 cases).Clinical data was collected,and the eGDR was calculated.Quasi-Bayesian method was used for causal mediation analysis.Results The prevalence of metabolic comorbidi-ties including hypertension,CHD,DM,hyperlipidemia,and hyperuricemia was significantly higher in the CKD group than the non-CKD group(P＜0.01).The eGDR was obviously lower in the CKD group than the non-CKD group[6.88±2.09 mg/(kg·min)vs 8.41±2.12 mg/(kg·min),P＜0.01].Logistic regression analysis revealed that,without adjusting covariates,each 1-unit increase in eGDR was associated with a 29％reduction in the risk of developing CKD(OR=0.714,95％CI:0.691-0.738,P＜0.01),and after adjusting covariates,eGDR remained signifi-cantly negatively association with the risk of CKD(P＜0.01).Mediation analysis indicated that DM and brachial-ankle pulse wave velocity accounted for the highest proportions of the mediating effect in the relationship between eGDR and CKD(14.2％and 12.5％,respectively).Conclusion In the elderly population undergoing health exam,reduced insulin sensitivity is significantly asso-ciated with the development of CKD.Diabetes and arteriosclerosis exert mediating effect in this association.

Objective To construct a risk prediction model for post-stroke dysphagia(PSD)based on clinical and laboratory indicators of elderly stroke patients with explainable machine learning.Methods A retrospective analysis was conducted on 3994 stroke patients hospitalized in Depart-ment of Neurology of First Medical Center of Chinese PLA General Hospital from October 2010 to December 2021.Among them,the 1390 cases admitted during January 2019 and December 2021 were assigned into an external validation set,and the 2604 cases admitted during October 2010 to January 2019 were into a training group.Those from the training group were further divided into a training set(1823 cases)and an internal validation set(781 cases)in a 7∶3 ratio,and also grouped into a PSD subgroup(773 cases)and a non-PSD group(1831 cases).With occurrence of swallowing difficulties as an endpoint,risk prediction models were constructed using random for-est(RF),eXtreme Gradient Boosting(XGBoost),Support Vector Machine(SVM),and logistic regression.ROC curve analysis was employed to evaluate the performance of our models.After the optimal model was selected,SHAP was employed to interpret feature contributions.Results There were significant differences in muscle strength,right/left-sided stroke,and area of brain in-jury between the PSD and the non-PSD groups(P＜0.01).The PSD group had obviously larger proportions of hypertension,diabetes,and drinking history,increased neutrophil counts,and de-creased levels of potassium and albumin when compared with the non-PSD group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that age,drinking history,diabetes,hyper-tension,muscle strength grade,area of brain injury,hemispheric stroke,neutrophil count,and al-bumin and potassium levels were risk factors for PSD(P＜0.05,P＜0.01).The external validation results showed that the area under curve value of the RF model,XGBoost model,SVM model,and our logistic model was 0.883,0.902,0.877,and 0.868,respectively.The distribution of SHAP value showed that drinking history,hypertension and diabetes were positively correlated with PSD risk;Muscle strength was negatively correlated with the risk;Age growth was positively correlated with the risk;Subtentorial lesions showed stronger predictive efficacy than supratentorial lesions and entire lesions;The bilateral and right-sided stroke had higher risk for PSD than the left-sided stroke.Conclusion The model based on the XGBoost model shows best performance in predicting the risk for swallowing disorders in elderly patients after stroke.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective To investigate the efficacy and safety of domestic RECO flow restoration device in endovascular treatment of acute ischemic stroke(AIS)patients in a real-world setting.Methods From January 2019 to June 2021,consecutive patients with acute intracranial vessel occlusion treated with RECO device from 8 stroke centers in Jiangsu Province were analyzed retrospectively.Baseline and clinical data were collected,including age,gender,baseline modified Rankin scale(mRS)scores,National Institutes of Health stroke scale(NIHSS)score on admission,trial of Org 10172 in acute stroke treatment(TOAST)classification,responsible location of occlusion,wake-up stroke,and medical history(hypertension,diabetes mellitus,hyperlipidemia,atrial fibrillation,coronary heart disease,peripheral arterial disease),smoking,and alcohol consumption.Furthermore,surgical parameters were collected,including time indicators(intervals between symptom onset,admission,puncture and recanalization),preoperative intravenous thrombolysis,general anesthesia,combination of aspiration,number of passes,first pass effect(modified thrombolysis in cerebral infarction[mTICI]grade 3 achieved with s single stent-based thrombectomy),rescue therapy(including thrombectomy with other stents,intra-arterial urokinase thrombolysis,intra-arterial application of tirofiban,emergency angioplasty[stent implantation,balloon dilatation,balloon dilatation combined with stent implantation]),balloon guided catheter and NIHSS score at discharge.The effectiveness indicators included immediate successful recanalization after the operation(mTICI grade ≥ 2b),complete recanalization(mTICI grade 3),and a good prognosis at 90 d after the operation(mRS score ≤2).The safety indicators included symptomatic intracranial hemorrhage(sICH)within 24 h after the operation,device-related intraoperative complications(such as thrombus escape,iatrogenic dissection,bleeding at the surgical site),and all-cause mortality within 90 days after the operation.All patients were divided into the anterior circulation occlusion group and the posterior circulation occlusion group according to the location of the responsible occluded vessel,and the effectiveness and safety indexes were analyzed.Results A total of 366 patients with AIS caused by intracranial vessel occlusion who underwent mechanical thrombectomy with the domestic RECO thrombectomy stent were included.The average age was(69±11)years,with 54 patients(14.8％)over 80 years old and 221 patients(60.4％)male.There were 296 patients in the anterior circulation occlusion group and 70 patients in the posterior circulation occlusion group.(1)Immediate successful recanalization(mTICI grade≥2b)was achieved in 337 patients(92.1％),and complete recanalization was achieved in 282 patients(77.0％)immediately after the operation.The average number of thrombectomies was(1.9±1.0)times,and 141 patients(38.5％)achieved recanalization on the first attempt.9 patients(2.5％)used other stents during the operation,and 65 patients(17.8％)underwent emergency angioplasty.The incidence of sICH within 24 h after the operation was 10.9％(40/366),the good prognosis rate at 90 d after the operation was 53.6％(196/366),and the all-cause mortality rate at 90 d after the operation was 23.0％(84/366).The incidence of device-related intraoperative complications was 3.6％(13/366).The median time from arterial puncture to recanalization was 75(52,110)min,and the median time from onset to recanalization was 370(280,488)min.(2)The good prognosis rates at 90 d after the operation in the anterior and posterior circulation occlusion groups were 55.1％(163/296)and 47.1％(33/70),respectively.The immediate successful recanalization rates were 93.2％(276/296)and 87.1％(61/70),respectively.The immediate complete recanalization rates were 79.1％(234/296)and 68.6％(48/70),respectively.The incidence of sICH within 24h after the operation was 12.2％(36/296)and 5.7％(4/70),respectively.The incidence of device-related intraoperative complications was 3.7％(11/296)and 2.9％(2/70),respectively.The all-cause mortality rate within 90 d after the operation was 21.6％(64/296)and 28.6％(20/70),respectively.There were no statistically significant differences between the two groups in the above aspects(all P＞0.05).Conclusions The application of the domestic RECO thrombectomy stent in the treatment of AIS caused by intracranial vessel occlusion can effectively and safely achieve vascular recanalization.The results of this study still need to be further verified by prospective controlled studies.
