This article summarizes Professor HAN Mingxiang's clinical experience in treating lung cancer based on the theory of "deficiency-phlegm-stasis-toxin". It is believed that depletion of healthy qi， together with binding of phlegm and stasis forming into toxin is the core pathogenesis of lung cancer occurrence and development. In clinical practice， the core treatment principle should be reinforcing healthy qi， resolving phlegm， removing stasis， and relieving toxins. The treatment should be given based on syndrome differentiation. For the syndrome of lung-spleen qi deficiency， the self-formulated Jianpi Huatan Zhike Decoction （健脾化痰止咳汤） can be applied to fortify the spleen and replenish qi， thereby reinforcing healthy qi. For the syndrome of deficiency of both qi and yin， the self-formulated Shenmai Yuzhu Decoction （参麦玉竹汤） is used to nourish yin and moisten the lungs， thereby clearing the source. For the syndrome of phlegm-dampness accumulating in the lungs， the self-formulated Sizi Wenfei Decoction （四子温肺汤） is applied to warm the lungs and resolve phlegm， thereby diffusing the lung qi. For the syndrome of qi stagnation and blood stasis， the self-formulated Yiqi Zhuyu Decoction （益气逐瘀汤） is used to activate blood and resolve stasis， thereby unblocking the collaterals. For the syndrome of binding of phlegm and stasis， the self-formulated Jiejie Decoction （结节方） is utilized to resolve phlegm and remove stasis， thereby dissipating nodules. For the syndrome of lung deficiency with toxin accumulation， the self-formulated Qiyu Sanlong Decoction （芪玉三龙汤） is applied to reinforce healthy qi and remove toxins， thereby combating cancer. Medications are flexibly prescribed based on syndrome differentiation， with an emphasis on reinforcing healthy qi and eliminating pathogenic factors， and maintaining the balance of zang-fu （脏腑） organ functions as well as qi， blood， yin and yang.

Objective To investigate the effects of active respiratory circulation technique(ACBT)combined with resistance breathing training on pulmonary function and exercise capacity in patients with acute exacerbations of chronic obstructive pulmonary disease(AECOPD).Methods A total of 60 hospitalized AECOPD patients from the Geriatrics Department of a tertiary hospital in Kunming were selected as research subjects from January to May 2024.Patients were randomly divided into two groups,with 30 patients in each group.The control group received conventional pulmonary rehabilitation nursing,and the observation group received ACBT combined with resistance breathing training.Pulmonary function indicators,modified British Medical Council(mMRC)dyspnea scores,6-minute walk test(6MWT)distances,and the COPD Assessment Test(CAT)scores were collected 4 weeks after discharge to evaluate the intervention's effectiveness.Results After the intervention,the observation group showed significant improvements in lung function,mMRC scores,6M WT distances,and CAT scores compared to pre-intervention levels,and all were superior to the control group(P＜0.05).Conclusion ACBT combined with resistance breathing training can more effectively promote sputum clearance,reduce respiratory muscle fatigue,increase exercise endurance,and improve dyspnea severity and lung function in AECOPD patients.

Objective:To investigate the ability of 18F-fibroblast activation protein inhibitor (FAPI) PET/CT imaging to identify involved myocardium in patients with hypertrophic cardiomyopathy (HCM) compared with cardiac MRI. Methods:A prospective study was conducted on 50 patients (32 males, 18 females, age (43±13) years) with HCM confirmed by ultrasound or cardiac MRI in Beijing Chaoyang Hospital from July 2021 to January 2022. All patients underwent both cardiac 18F-FAPI PET/CT and MRI. The SUV max and maximum target-to-background ratio (TBR max) of the left ventricular myocardium were obtained using post-processing software. Regions with 18F-FAPI uptake not less than predefined thresholds (SUV max 40%, 50%, 60%) were defined as myocardium with positive uptake. The FAPI amount was defined as the product of TBR max and the extent of FAPI-positive uptake (FAPI%). Cardiac MRI post-processing software was used to measure the extent of left ventricular myocardial late gadolinium enhancement (LGE) (expressed as LGE%), native T 1 value, extracellular volume fraction (ECV), and myocardial deformation characteristics. Spearman rank correlation analysis was employed to assess the correlation between 18F-FAPI imaging parameters and cardiac MRI parameters, as well as the correlation between FAPI amount and the 5-year risk score for sudden cardiac death (SCD). Linear regression analysis was utilized to identify factors associated with FAPI amount. Results:When the threshold for 18F-FAPI-positive uptake in the left ventricular myocardium was set at 60%, the correlations between FAPI amount, FAPI%, and MRI parameters were optimal ( rs values: from -0.465 to 0.460, all P<0.05). Multivariate linear regression analysis revealed that HCM duration ( β=0.128, 95% CI: 0.022-0.233, P=0.008), serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels ( β=0.190, 95% CI: 0.099-0.280, P<0.001), and left ventricular ejection fraction ( β=-0.005, 95% CI: -0.011 to 0.000, P=0.041) were independent predictors of FAPI amount. FAPI amount was positively correlated with the 5-year SCD risk score across different thresholds (40%: rs=0.32, P=0.026; 50%: rs=0.29, P=0.039; 60%: rs=0.29, P=0.040). Conclusions:When the threshold for 18F-FAPI-positive uptake is set at 60%, 18F-FAPI PET/CT imaging can more effectively identify the involved myocardium in HCM. FAPI amount is correlated with the 5-year SCD risk score in patients with HCM.

Objective:To study the risk factors and the molecular epidemiology characteristics for Carbapenem-resistant Enterobacteriaceae(CRE) colonization in neonatal inpatients in Shenzhen region, China, which provide reference for the prevention and control of clinical CRE infection.Methods:This study is a prospective case-control study.Anal samples from inpatients between January 2023 and December 2023 at Longgang Maternity and Child Institute of Shantou University Medical College and Shenzhen Children's Hospital were collected for screening CRE strain. Drug susceptibility test, modified Carbapenem Inactivation Method (mCIM) test, drug resistance-related gene sequencing and multilocus sequence typing (MLST) were performed for isolated CRE strains.Meanwhile, the clinical data were collected for analyzing the risk factors of CRE intestinal colonization by multivariate regression analysis.Results:A total of 1 517 patients were screened, 26 CRE(1.7%, 26/1 517) were identified which including 14 Escherichia coli(53.8%, 14/26), 11 Klebsiella pneumoniae(42.3%, 11/26), 1 Enterobacter cloacae(3.9%, 1/26). The predominant carbapenemase gene was New Delhi Metallo(NDM) (92.4%, 24/26), followed by Imipenem (IMP) (3.8%, 1/26) and Guiana extended spectrum gene (GES) (3.8%, 1/26).Among the carried NDM resistance genes, New Delhi Metallo 5 (NDM5) was the main one, accounting for 84.6% (22/26).The MLST typing of Escherichia coli was mainly Sequence Type 48 (ST48) (6/14), while that of Klebsiella pneumoniae was mainly Sequence Type 35 (ST35) (10/11). All CRE isolates were resistant to penicillin, penicillinase inhibitors, cephalosporins, ertapenem and imipenem.The resistance rates of Escherichia coli to amikacin, levofloxacin was 1/14, 4/14, respectively. All isolates of Klebsiella pneumoniae were sensitive to amikacin, and the resistance rate to levofloxacin is 1/11. Risk factors for CRE colonization include the older age, length of hospital stay, tracheal intubation, invasive respiration, lumbar puncture, Apgar <7 score, and exposure to antibiotics.Conclusions:NDM5 is the predominant resistant gene in CRE isolated from neonatal patients feces in Shenzhen region.It is necessary to strengthen the screening of CRE colonization in neonate for prevention and control of CRE infection.

Objective To investigate the expression and mechanistic role of the M2-type pyruvate kinase(PKM2)/signal transducer and activator of transcription 3(STAT3)signaling pathway in the development of experimental autoim-mune uveitis(EAU).Methods Eighteen 4-to 5-week-old C57BL/6J mice were selected and randomly divided into a control group(normal breeding,set as the 0-day state post-modeling),Experimental Group A,and Experimental Group B(both established as stable EAU mouse models using the interphotoreceptor retinoid-binding protein peptide 651-670,com-plete Freund's adjuvant,and pertussis toxin,designated as the 14-day and 21-day states post-modeling,respectively),with 6 mice in each group.The anterior segment of the mice was observed using a slit-lamp microscope,fundus findings were collected using a fundus camera,and clinical and histopathological scores were evaluated after hematoxylin-eosin stai-ning.The protein expression level of serum interleukin(IL)-17A was detected by ELISA.The expression level of PKM2 protein in retinal tissue was detected by immunohistochemistry.The protein expression levels of PKM2,phosphorylated STAT3(p-STAT3),and STAT3 in mouse retinal tissue were detected by Western blot.Results The clinical scores of the anterior segment and fundus,as well as the retinal histopathological scores in Experimental Group A and Experimental Group B,were all significantly higher than those in the control group(all P＜0.05).The serum IL-17A protein expression levels in the control group,Experimental Group A,and Experimental Group B were(69.05±0.45)ng·L-1,(75.06±0.46)ng·L-1,and(72.04±0.82)ng·L-1,respectively.The optical density values of PKM2 protein expression in retinal tissue were(18.51±2.59)％,(37.35±4.67)％,and(29.75±2.17)％,respectively.The expression levels of serum IL-17A protein,retinal PKM2 protein,and retinal STAT3 and p-STAT3 proteins in Experimental Group A and Experimental Group B were all significantly higher than those in the control group(all P＜0.05).Conclusion The expression levels of key factors in the PKM2/STAT3 signaling pathway are positively correlated with the severity of EAU,indicating that this sig-naling pathway,as a positive regulator of the immune response,is involved in the pathological process of EAU.

Objective To differentiate disguised visual acuity,(VA)by analyzing discrepancies across diversified visual acuity tests.Methods Volunteers were recruited,and VA(V,and V2)was measured before and after the experiment.Volunteers independently selected an experimental VA(Vt)and were assigned to either the disguised group or the control group.A specially designed heterogeneous optotype chart and a single-optotype chart with variable test distances were used to measure VA(t1,t2,t3),while a standard logarithmic VA chart was used to measure VA(t4).Based on the maximum VA discrepancy(△t),t4 was classified as"real"(≤ 1 line),"disguised"(≥ 2 lines),or"suspicious"(＞1 and＜2 lines with anomaly).Results A total of 126 valid cases were collected,including 30 in the control group and 96 in the disguised group,with VA ranging from 0.2～1.5.All 88 opinions classified as"disguised"were from the disguised group,and all 29 classified as"real"were from the control group.Of the 7 cases deemed"suspicious,"6 were from the disguised group.The sensitivity,specificity,and overall diagnostic accuracy were 91.7％,96.7％(P＜0.0001),and 92.9％(P＜0.0001),respectively.In the disguised group,38 cases exhibited unexplained identifying anomalies.Conclusion A VA discrepancy of ≥ 2 lines is a reliable indicator for detecting disguised visual acuity.Identifying anomalies may serve as a novel and sensitive marker for recognizing visual disguise.

Objective To compare the ability of single-phase,dual-phase,and triphasic models in forecasting postoperative pancreatic fistula(POPF)after pancreaticoduodenectomy(PD)using radiomics based on triphasic enhanced CT.Methods A total of 181 patients who underwent multi-phase enhanced CT prior to PD were retrospectively selected,and the collection phase included non-contrast,arterial phase(AP),and equilibrium phase(EP).3D Slicer software was utilized to segment the region of interest(ROI)for the postoperative pancreatic remnant on each phase.Radiomics feature extraction was performed using R software,followed by feature selection through least absolute shrinkage and selection operator(LASSO)regression with five-fold cross-validation to prevent model overfitting.The effective features selected were combined in a weighted linear manner to obtain a Radiomics score(Radscore).The patients were divided into training set and test set in a 7︰3 ratio.Logistic regression was employed to construct seven POPF prediction models(three single-phase,three dual-phase,and one triphasic models)based on different phase combinations.The diagnostic performance of the models was evaluated using the area under the curve(AUC)of receiver operating characteristic(ROC)curve,accuracy(ACC),sensitivity(SEN),and specificity(SPE).The DeLong test was applied to compare the differences in AUC among different models.Results After LASSO regression,24 effective features associated with POPF were selected from different phases.In the test set,the triphasic model exhibited the highest AUC and ACC(AUC=0.76,ACC=0.808).The calibration curve demonstrated the strongest agreement between the estimated probabilities and observed probabilities for the triphasic model.The decision curve analysis(DCA)curve indicated that the triphasic model had the largest threshold range with a higher net benefit.Conclusion Compared with single-phase and dual-phase models,the triphasic model based on enhanced CT provides better prediction of POPF after PD,aiding clinical decision-making and improve prognosis.
