Breast cancer remains a substantial threat to women's health and is one of the most prevalent malignant tumors in women.Because breast cancer onset is closely associated with female physiological characteristics,this article proposes that breast cancer be classified as a"women's miscellaneous diseases"and that its treatment be explored from this perspective.Drawing from Chapter 8 on Golden Chamber of Prescriptions for Miscellaneous Diseases in Women of Synopsis of Golden Chamber,the initial pathogenesis of breast cancer is associated with"emotional stress,improper lifestyle,deficiency,cold,and stagnation."The fundamental mechanism behind its formation is"blood cold accumulation and hardened masses."Specifically,emotional imbalance and improper lifestyle habits contribute to the combined invasion of the uterus by"deficiency,""accumulated cold,"and"stagnant qi."Over time,"cold-blood stasis accumulates at the uterine ostium,"and the cold and the stasis ascends from the uterus along the thoroughfare and conception vessels,obstructing the breast collaterals.This combination of yang qi stagnation and yin cold congealment,ultimately leads to the development of breast cancer.The treatment principle should focus on"activating yang and dispersing cold."A therapeutic approach centered on Wenjing Decoction combined with Xiaoyao Powder can be adapted based on the stage and type of breast cancer while also considering the dynamic interplay between pathogenic factors and healthy qi,along with shifts in deficiency and excess patterns of disease.By adhering to the principles of consistency and flexibility and integrating disease and syndrome differentiation,the goal is to develop precise and personalized treatment strategies to improve clinical outcomes.

Objective To report cases of checkpoint inhibitor pneumonitis （CIP） in patients with advanced biliary tract cancer, aiming to provide additional approaches for the assessment, treatment, and monitoring of this condition. Methods Three patients developed oxygen desaturation and interstitial lung lesions during chemotherapy combined with immunotherapy, and were diagnosed with CIP in collaboration with the respiratory department. Antitumor therapy was discontinued in the acute phase, and glucocorticoids were administered, with regular monitoring of disease progression. During follow-up, case 1 developed lung metastasis; case 2 showed improvement; case 3 had concurrent infection and tumor progression. Results Glucocorticoids improved lung lesions and hypoxic symptoms in patients with CIP, but attention should be paid to the potential for concurrent infections and tumor progression. Conclusions Comprehensive assessment and early identification of CIP are crucial for patients with advanced biliary tract cancer. For those with recurrent symptoms after glucocorticoid therapy, timely and accurate adjustment of the treatment regimen is essential.

Objective To investigate the clinical efficacy of the"dynamic and static combination"approach in the treatment of Hepple Ⅰ-Ⅲ type osteochondral lesions of the talus(OLT),utilizing external ankle shaking,pulling,and poking manipulations in conjunction with ankle brace fixation.Methods A total of 82 patients diagnosed with OLT,who sought treatment at four hospitals between June 2022 and December 2023,were included in the study.Both the experimental and control groups received ankle immobilization using braces through-out the treatment period.The control group was administered Voltaren Emulgel topically twice daily(morning and evening),with each treatment course lasting 30 days,for a total of one course.The experimental group received additional therapeutic intervention involving shaking,pulling,and poking manipulations,conducted twice weekly,with the same duration and number of treatment courses as the control group.Follow-up assessments were scheduled at 2 weeks,4 weeks,and 2 months post-treatment.Outcome measures included the pain rating index(PRI),visual analogue scale(VAS)for pain intensity,current pain intensity(PPI),American Orthopaedic Foot & Ankle Society(AOFAS)ankle and hindfoot scores,proprioceptive function,and the size of OLT.Results During the longitudinal assessment conducted at 2-week,4-week,and follow-up intervals,the experimental group exhibited superior clinical outcomes compared to the control group,with statistically significant decreases in PRI,PPI,and AOFAS scores(all P＜0.05).VAS scores showed progressive improvement over time,with significant intergroup differences observed at both the 4-week and follow-up assessments(P＜0.05).Biomechanical analysis performed post-intervention indicated improved kinematic repositioning accuracy in the experimental group,as reflected by significantly reduced active-passive error angles(P＜0.05).Importantly,measurements of OLT area revealed notable therapeutic effects in the experimental group(P＜0.05),whereas no statistically significant changes were observed in the control group throughout the study period(all P＞0.05).Conclusions Under the guidance of the"dynamic and static combination"concept,the integration of shaking,pulling,and poking manipu-lation with conventional Western medicine-based conservative treatment for OLT demonstrates more pronounced advantages in alleviating pain,improving ankle joint function,restoring proprioception,facilitating lesion recovery,and enhancing overall quality of life.

Objective To analyze the resistance mechanism,characteristics of drug sensitivity,and homology of polymyxin resistant Escherichia coli,and provide molecular epidemiological basis for the effective prevention and control of its outbreak and epidemic.Methods The strains of polymyxin resistant Escherichia coli isolated from our hospital during May 2016 and June 2022 were collected.The PCR technology was used to screen for the mobile colistin resistance(MCR)gene and the micro broth dilution method was used to determine the minimum inhibitory concentration.The clinical data of the patients were collected.The homology of the collected strains was analyzed by the pulsed field gel electrophoresis(PFGE).One of the strains was performed whole genome sequencing.Results Four strains of polymyxin resistant Escherichia coli carrying the MCR-1 gene were isolated and identified.Except for being sensitive to tigecycline,all four strains showed varying degrees of resistance to the vast majority of clinically common antibiotics.Clinical data showed that no polymyxin was used in the patients with polymyxin resistant Escherichia coli.The four strains of bacteria could be divided into two types,including three strains of type A and one strain of type B.The whole genome sequencing analysis of one of the bacteria revealed that the MCR-1 gene was located on a plasmid with a size of 70 kb.Conclusion The Escherichia coli carrying the MCR-1 gene has a potential threat to clone transmission and exhibits high resistance to common antibiotics in clinical practice,posing a serious challenge to clinical treatment.Therefore,it is necessary to strengthen protective measures to prevent its outbreak and epidemic.

Left atrial reverse remodeling refers to the reversal of left atrial structure,function,and electrical remodeling,and the restoration of left atrial morphology,functional parameters,and myocardial tissue,which mostly indicates that the disease is on the way of improvement.Heart failure with recovered ejection fraction (HFrecEF) has become an entity of widespread concern,and the progression of the disease is related to the nature and severity of myocardial injury,rather than being limited to the trajectory of left ventricular ejection fraction (LVEF) changes.In recent years,it has been found that the left atrial reverse remodeling is closely related to the prognosis,risk stratification,and drug selection of patients with HFrecEF.This article reviews the definition,pathophysiology,evaluation methods of left atrial reverse remodeling in patients with heart failure,its application in patients with HFrecEF,and the controversies and related considerations in the diagnosis of left atrial reverse remodeling.

Objective:To investigate the effects of nicorandil combined with thrombus aspiration during percutaneous coronary intervention on reperfusion arrhythmia in patients with acute ST-elevation myocardial infarction.Methods:180 patients with acute ST-elevation myocardial infarction who received treatment in Yidu Central Hospital, Weifang Medical University, China between January 2019 and June 2020 were included in this study. They were randomly assigned to receive either nicorandil combined with thrombus aspiration during percutaneous coronary intervention (NPCI group, n = 90) or conventional PCI (PPCI group, n = 90). Myocardial perfusion (myocardial blush grade 3 blood flow) and the occurrence of reperfusion arrhythmia within 24 hours after treatment were compared between the NPCI and PPCI groups. Results:The incidence of myocardial blush grade 3 blood flow in the NPCI group was significantly higher than that in the PPCI group [84.44% (76/90) vs. 68.88% (62/90), χ2 = 6.01, P = 0.01]. There was no significant difference in the total incidence of reperfusion arrhythmia between NPCI and PPCI groups ( χ2 = 1.19, P = 0.27). The incidence of severe reperfusion arrhythmia in the NPCI group was significantly lower than that in the PPCI group [13.33% (12/90) vs. 27.77% (25/90), χ2 = 5.75, P = 0.02]. The influential factor of severe reperfusion arrhythmia was analyzed by logistic regression taking whether NPCI treatment was used as the variable ( OR = 0.40, 95% CI 0.18-0.89, P = 0.02). The other factors that affect severe reperfusion arrhythmia included age ( OR = 0.71, 95% CI 0.19-0.92, P = 0.04), time from onset to reperfusion of infarct related artery ( OR = 0.62, 95% CI 0.21-0.98, P = 0.02), dcuhistory of pre-infarct angina pectoris ( OR = 0.67, 95% CI 0.19-0.98, P = 0.03), admission blood glucose level ( OR = 1.96, 95% CI 1.05-5.78, P = 0.03), admission leukocyte count ( OR = 1.99, 95% CI 1.02-6.18, P = 0.03) and cardiac function ( OR = 1.71, 95% CI 1.06-6.91, P = 0.04). Conclusion:Nicorandil combined with thrombus aspiration during percutaneous coronary intervention for the treatment of acute ST-elevation myocardial infarction can not only improve myocardial perfusion, but also reduce the incidence of reperfusion arrhythmia. The combined therapy is superior to monotherapy, has certain clinical significance and is innovative.

Objective: To investigate the clinical and microbiological characteristics of Myroides odoratimimus producing MUS-1 carbapenemase. Methods: A strain of gram-negative bacterium isolated from the urine sample of one patient hospitalized in the oncology department of Affiliated Hospital of Xuzhou Medical University was identified by the Vitek 2 automatic microbial analyzer and 16S RNA sequencing, and its bla MUS-1 gene was detected with PCR. The minimum inhibitory concentrations (MICs) of antimicrobial drugs were determined by the broth dilution method. Results: One strain of MUS-1 carbapenemase producing Myroides odoratimimus was found. The drug susceptibility test showed that it was resistant to most of antibiotics conventionally used, but sensitive to minocycline and meropenem, the MIC of imipenem was 8 μg/mL, which was judged as intermediate. Conclusion The bla MUS-1 gene may be the cause leading Myroides odoratimimus to resistant carbapenems drugs.
