This article systematically summarized the clinical experience of Professor Han Mingxiang,a national TCM master,in treating chronic obstructive pulmonary disease(COPD)from the perspective of the"qi monism"theory,proposing an innovative"three stages,three strategies"diagnostic and treatment approach.Under the guidance of"qi monism",Professor Han believes that the core pathological mechanisms of COPD progress are through three successive stages:dysfunction in the ascent and descent of qi,deficiency of yang qi,and prolapse of the great qi,all of which stem from the disruption of the dynamic balance of qi.In response to this chain of qi imbalance,Professor Han develops three strategies:"strengthening the foundation","illuminating the central yang",and"lifting and correcting",which aim to regulate qi flow,support yang qi,and coordinate the three energizers in a phased manner.This approach seeks to achieve dynamic restoration and holistic balance of qi,with prescriptions carefully aligned with the dynamic balance and pathological changes of qi,yielding distinctive therapeutic effects.

This study systematically elucidates the contemporary understanding of the theory of"the lung and large intestine being interior-exteriorly related"within both traditional Chinese and Western medical theoretical frameworks,while providing an in-depth summary of national medical master Han Mingxiang's clinical experience in diagnosing and treating phlegm-heat obstructing lung syndrome in acute exacerbation chronic obstructive pulmonary disease(AECOPD).Theoretically,this doctrine originates from the Huangdi Neijing and has been developed into a comprehensive system by subsequent medical practitioners.Modern medical research from embryological,microbiological,and other perspectives has confirmed the close physiological and pathological relationship between the lung and intestine,particularly evidenced by the proposed"gut-lung axis"theory.Based on over 6 decades of clinical practice,professor Han identified the core pathogenesis of AECOPD as involving"phlegm,blood stasis,toxins,and deficiency,"with phlegm-heat obstructing lung syndrome being the most prevalent manifestation.The pathological characteristics include impaired lung qi descent,internal accumulation of phlegm-heat,and intestinal obstruction.The therapeutic approach emphasizes"clearing heat and resolving phlegm,relieving cough and asthma"as the primary treatment principle,focusing on"clearing lung heat,eliminating phlegm pathogens,and descending rebellious qi",while adhering to the concept of"simultaneous treatment of lung and intestine."In terms of herbal prescription,professor Han skillfully employs modified Xuanbai Chengqi decoction,which integrates lung-ventilating,phlegm-resolving,and purgative effects.Importantly,he emphasizes the precise timing and dosage of purgative herbs,particularly for patients with deficiency patterns,advocating discontinuation or dose reduction once intestinal patency is achieved to avoid overtreatment.For remission phase management,professor Han advocates the"reinforcing earth to generate metal"approach using modified Bufei decoction combined with Yigong powder,which strengthens spleen qi to nourish lung function.This therapeutic strategy embodies the fundamental treatment principle of"treating the acute manifestations first,then addressing the root cause."This research not only deepens the understanding of classical Chinese medical theories but also provides more scientifically grounded intervention strategies for the clinical prevention and treatment of lung distension.The findings offer valuable insights into integrative approaches for AECOPD management,combining traditional wisdom with contemporary medical understanding.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

This paper summarized the experience of Chinese medical master Han Mingxiang in treating pathogenic-damp caused diseases by the method of dispelling dampness.Han Mingxiang believes that refractory diseases are usually caused by pathogenic cold and dampness,and complicated diseases are usually caused by phlegm and stagnation.Predominant dampness causes the inactivation of yang,and warming therapy is not the only one choice for activating yang.In clinical practice,he emphasizes the principles for dispelling dampness mainly by simultaneous treatment of phlegm and qi,lifting lucid yang and lowering turbid yin,nourishing spleen and resolving dampness,expelling and resolving pathogens by elevation and dispersion,relieving exterior and activating yang,which is summed up as"warming,resolving,dispersing and activating,regulating qimovement".For the treatment of the diseases caused by pathogenic-damp,the warm-natured medicines are usually used frequently,and the warm-natured medicines are not limited to the pungent-warm medicine.For dispelling dampness,the method of relieving exterior and promoting qi movement,percolating and draining dampness with aromatics,and relieving fluid retention with pungent-sweet medicine can be chosen flexibly based on syndrome differentiation,thus to reach the goal of activating yang and resolving stagnation and to obtain satisfactory efficacy.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.

Genomic studies of cancer cell alterations,such as mutations,copy number variations(CNVs),and translocations,greatly promote our understanding of the genesis and development of cancers.However,the 3D genome architecture of cancers remains less studied due to the complexity of cancer genomes and technical difficulties.To explore the 3D genome structure in clin-ical lung cancer,we performed Hi-C experiments using paired normal and tumor cells harvested from patients with lung cancer,combining with RNA sequenceing analysis.We demonstrated the feasibility of studying 3D genome of clinical lung cancer samples with a small number of cells(1×104),compared the genome architecture between clinical samples and cell lines of lung cancer,and identified conserved and changed spatial chromatin structures between normal and cancer sam-ples.We also showed that Hi-C data can be used to infer CNVs and point mutations in cancer.By integrating those different types of cancer alterations,we showed significant associations between CNVs,3D genome,and gene expression.We propose that 3D genome mediates the effects of cancer genomic alterations on gene expression through altering regulatory chromatin structures.Our study highlights the importance of analyzing 3D genomes of clinical cancer samples in addition to cancer cell lines and provides an integrative genomic analysis pipeline for future larger-scale studies in lung cancer and other cancers.

Objective To study the effect of levosimendan on cardiomyocyte apoptosis after coronary microembolization (CME) in swine,Methods Fifteen healthy swines were randomly divided into sham operation group,CME group and levosimendan treatment group (5 in each group).Their cardiac function was assessed by echocardiography,their cardiomyocyte apoptosis was assyed with TUNEL staining,and Caspase-3 expression was detected by Western blot at 12 h after operation.Results The LVEF was lower,the left ventricular minor axis was shorter and the cardiac output volume was smaller while the LVEDD was longer in CME group than sham operation group (P＜0.05).The cardiac function was significantly better in CME group than in sham operation group (P＜0.05).The cardiomyocyte apoptosis rate and Caspase-3 expression level were significantly higher in CME group than in sham operation group (P＜0.05).The cardiomyocyte apoptosis rate was significantly higher while the Caspase-3 expression level was significantly lower in levosimendan treatment group than in CME group (6.820％±-1.974 ％ vs 10.558％±2.425％,P＜0.05).Conclusion Pretreatment with levosimendan can effecively reduce the cardiomyocyte apoptosis and improve the cardiac function after CME by inhibiting the Caspase-3 expression in cardiomyocytes.

Objective: To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. Methods: This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1. The course of treatment was 48 weeks and the patients were followed up for 24 weeks after drug withdrawal. Plasma samples were collected at screening, baseline, and 12, 24, 36, 48, 60, and 72 weeks for centralized detection. COBAS® Ampliprep/COBAS® TaqMan® HBV Test was used to measure HBV DNA level by quantitative real-time PCR. Electrochemiluminescence immunoassay with Elecsys kit was used to measure HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe). Adverse events were recorded in detail. The primary outcome measure was HBeAg seroconversion rate after the 24-week follow-up, and non-inferiority was also tested. The difference in HBeAg seroconversion rate after treatment between the trial group and the control group and two-sided confidence interval (CI) were calculated, and non-inferiority was demonstrated if the lower limit of 95% CI was > -10%. The t-test, chi-square test, or rank sum test was used according to the types and features of data. Results: A total of 855 HBeAg-positive CHB patients were enrolled and 820 of them received treatment (538 in the trial group and 282 in the control group). The data of the full analysis set showed that HBeAg seroconversion rate at week 72 was 27.32% in the trial group and 22.70% in the control group with a rate difference of 4.63% (95% CI -1.54% to 10.80%, P = 0.1493). The data of the per-protocol set showed that HBeAg seroconversion rate at week 72 was 30.75% in the trial group and 27.14% in the control group with a rate difference of 3.61% (95% CI -3.87% to 11.09%, P = 0.3436). 95% CI met the non-inferiority criteria, and the trial group was non-inferior to the control group. The two groups had similar incidence rates of adverse events, serious adverse events, and common adverse events. Conclusion In Peg-IFN-α regimen for HBeAg-positive CHB patients, the new drug Peg-IFN-α-2b (Y shape, 40 kD) has comparable effect and safety to the control drug Peg-IFN-α-2a.
