Granulation tissue hyperplasia after tracheotomy is a common clinical complication. Endoscopic treatment can temporarily relieve airway obstruction， however， it is associated with a high recurrence rate and poor long-term prognosis. Based on the traditional Chinese medicine （TCM） Kenang （窠囊） theory and combined with modern pathological mechanisms， this paper explores its correlation with the pathogenesis of post-tracheotomy granulation tissue hyperplasia. Drawing from clinical experience in applying the Kenang theory for treatment， this paper proposes that the fundamental pathogenesis of this condition lies in qi deficiency and organ dysfunction， while phlegm and blood stasis interlocking serve as the symptomatic manifestations. The treatment focuses on resolving phlegm and promoting blood circulation， dispersing nodules and eliminating stagnation， regulating qi flow， and reinforcing the body's vital energy while expelling pathogenic factors. This approach aims to dissolve phlegm and blood stasis， dissipate the Kenang， and ultimately prevent and treat granulation tissue hyperplasia.

Objective·To analyze the clinicopathologic characteristics of patients with kidney-involved diffuse large B-cell lymphoma(DLBCL),including clinical characteristics,pathological characteristics,gene mutation profiles,and prognostic factors.Methods·One hundred and forty-nine patients with kidney-involved DLBCL,admitted to Ruijin Hospital,Shanghai Jiao Tong University School of Medicine from July 2005 to November 2021,were retrospectively analyzed for their clinicopathological data,survival and prognostic factors,which included therapeutic methods,clinical outcomes,staging,etc.Gene mutation profiles were evaluated by targeted sequencing of 54 lymphoma-related genes.Prognostic factors were also analyzed based on the information mentioned above.Results·A total of 149 kidney-involved DLBCL cases were included,of which 89 patients(58.4%)were aged over sixty,121 patients(81.2%)were staged Ann Arbor Ⅲ?Ⅳ,27 patients(18.1%)had an Eastern Cooperative Oncology Group(ECOG)performance status of two or more,121 patients(81.2%)had elevated serum lactate dehydrogenase(LDH)level,111 patients(74.5%)had extranodal invasion in at least two organs and 131 patients(87.9%)scored over 2 points on the international prognosis index(IPI).The estimated 5-year overall survival(OS)rate and progression-free survival(PFS)rate of kidney-involved DLBCL patients were 52.2%and 50.4%respectively.Univariate analysis revealed that elevated serum LDH levels were an adverse prognostic factor for both OS(P=0.048)and PFS(P=0.033).In pathological characteristics,145 patients(97.3%)belonged to DLBCL,not otherwise specified(NOS)and 39 patients(26.3%)belonged to germinal center B-cell(GCB)according to Hans classification.Among 144 patients who could be evaluated for clinical outcomes,87 patients(60.4%)got complete response(CR).Targeted sequencing data from 75 kidney-involved DLBCL patients showed high mutation frequency in PIM1(n=23,31%),MYD88(n=22,29%),CD79B(n=21,28%)and KMT2D(n=18,24%),with CD79B mutation indentified as an adverse prognostic factor for OS in patients with kidney-involved DLBCL(P=0.034).Conclusion·Elevated serum LDH level is an adverse prognostic factor in patients with kidney-involved DLBCL.The prognosis of patients with CD79B mutations is poor.

Objective To explore whether Yes-associated protein(YAP)affects occurrence and progression of liver fibrosis by regulating epithelial-mesenchymal transition(EMT).Methods In a 8-week-old C57BL/6 mouse model of CCl4-induced liver fibrosis,the effect of verteporfin(a YAP inhibitor)intervention was assessed with HE staining and by detecting liver biochemistry and expressions of YAP and EMT-related genes using immunohistochemistry and Western blotting.Transcriptome and proteomic sequencing and informatics analysis were used to investigate the main downstream pathways of YAP in liver fibrosis.Serum levels of YAP,N-cadherin,vimentin and Twist were examined in 60 healthy individuals,60 patients with chronic hepatitis B(CHB),and 60 patients with HBV-related liver cirrhosis.In another 24 C57BL/6 mice,the effects of Twist inhibitor alone or in combination with harmine(a YAP activator)on CCl4-induced liver fibrosis were evaluated by histopathological examination and Western blotting.Results The mouse models of liver fibrosis showed obvious structural damages of the liver lobes with formation of pseudolobules,and verteporfin treatment significantly improved these pathologies and lowered plasma ALT and AST levels of the mice.Transcriptome and proteomic sequencing and informatics analysis suggested that N-cadherin and Twist were differentially expressed in liver fibrosis in close correlation with YAP.Inhibition of YAP obviously downregulated hepatic N-cadherin and Twist protein expressions in the mice with liver fibrosis.In patients with CHB and liver cirrhosis,serum levels of YAP elevated obviously with the severity of liver fibrosis and were significantly correlated with N-cadherin,vimentin and Twist levels.In mice with liver fibrosis,inhibiting Twist effectively improved liver inflammation and fibrosis,while the combined treatment with YAP activator worsened hepatic collagen fiber deposition and increased hepatic YAP and α-SMA expressions.Conclusion EMT is an important pathogenic mechanism of liver fibrosis,and inhibiting YAP can alleviate liver fibrosis by reducing EMT.

Objective To explore the related risk factors of hypokalemia in elderly patients with acute cerebral hemorrhage(ACH),and construct a risk prediction model based on logistic regres-sion.Methods A total of 190 elderly ACH patients treated in Foshan Hospital of Traditional Chi-nese Medicine from June 2022 to May 2024 were enrolled as study objects,and were divided into hypokalemic group(potassium＜3.5 mmol/L,n=51)and normal group(potassium 3.5-5.5 mmol/L,n=139)according to whether hypokalemia occurred.Logistic regression model was used to analyze the risk factors of hypokalemia in the elderly ACH patients.Based on the identified risk factors,a comprehensive index model was constructed.ROC curve was drawn to analyze the diag-nostic value of the index for occurrence of hypokalemia in the patients.Results Larger female ra-tio,higher NIHSS score at admission,elevated urea nitrogen and blood creatinine at admission,and higher glomerular filtration rate(GFR)≤60 ml/min,and ratio of using hydrochlorothiazide＞20 mg/d were observed in the hypokalemic group than the normal group(P＜0.01).Univariate logistic regression analysis showed that female,NIHSS score at admission,urea nitrogen at ad-mission,serum creatinine at admission,GFR ≤60 ml/min,and hydrochlorothiazide dose＞20 mg/d were risk factors for hypokalemia in the ACH patients(P＜0.05,P＜0.01).Multivariate lo-gistic regression analysis indicated that female,NIHSS score at admission,GFR ≤60 ml/min,and hydrochlorothiazide dose＞20 mg/d were independent risk factors for hypokalemia in the elderly ACH patients(OR=6.393,95％CI:2.138-19.112,P=0.001;OR=3.123,95％CI:2.161-4.513,P=0.000;OR=3.327,95％CI:1.137-9.736,P=0.028;OR=3.111,95％CI:1.083-8.933,P=0.035).ROC curve analysis revealed that the AUC values of female,NIHSS score at admission,GFR,hydrochlorothiazide dose and comprehensive index in predicting hypokalemia in elderly ACH patients were 0.621,0.897,0.601,0.613 and 0.857,with a sensitivity of 52.90％,76.50％,49.00％,54.90％and 72.50％,and a specificity of 71.20％,88.50％,71.20％,67.60％and 87.80％,respectively.Conclusion Female,NIHSS score at admission,GFR ≤60 ml/min,and hydrochlorothiazide dose＞20 mg/d may affect the occurrence of hypokalemia in elderly ACH pa-tients,and our comprehensive index model based on these risk factors has high performance in predicting the occurrence of hypokalemia in elderly ACH patients.

Myocardial ischemia/reperfusion injury(MIRI)occurs after cardiopulmonary bypass open heart surgery,cardiovascular intervention and thrombolytic therapy,which is the most important cause of cardiac insufficiency,heart fail-ure,and even death in patients after treatment.In recent years,studies have found that the release of endogenous active peptides can alleviate the production of MIRI,and regulating the function and action of endogenous peptides may be one of the most effective ways to treat MIRI.Dipeptidyl peptidase 4(DPP4)is an important serine protease in mammals,with enzymatic activity to hydrolyze endogenous peptides.Its primary physiological function is to metabolize short peptides,in-cluding growth factors,hormones,etc.This review aims to better understand and search for effective therapeutic targets by elucidating the impact of DPP4 on the hydrolysis of endogenous peptides in MIRI,and ultimately provide new ideas for the therapeutic effects of MIRI.

Objective:To determine a relationship between ultrasound shear wave elastography (SWE) and pathological lessions of renal tissues in children with chronic kidney disease (CKD).Methods:It was a cross-sectional observational study, involving children admitted to the Department of Pediatrics of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January to December 2021 with definite pathological diagnosis through kidney biopsy. The SWE was used to determine the Young's modulus (elastic modulus) of the cortex and medulla of the upper, middle, and lower poles of the kidney. The renal histopathology was classified or graded. The statistical method was used to analyze the relationship between Young's modulus of the inferior polar cortex (YM cor) and medulla (YM med) of the right kidney and renal pathology. Results:The study included 110 children with definite pathological diagnosis through renal biopsy, aged (10.1±3.4) years old (2-17 years old), with 55 males (50.0%). The body mass index was (20.6±2.4) kg/m 2, and mean arterial pressure was (95±24) mmHg. There were 94 patients (85.4%) with CKD stage 1, 8 patients (7.3%) with CKD stage 2, and 8 patients (7.3%) with CKD stage 3. There was no significant difference of YM cor and YM med in the upper and middle poles of the right kidneys, and YM med in the lower poles of right kidneys in CKD patients with different stages (all P>0.05). Both YM cor [(15.75±3.36) kPa] and YM med [(13.50±2.43) kPa] of CKD stage 3 patients were significantly higher than those of CKD stage 1 patients [(12.94±2.45) kPa, (11.88±2.23) kPa](both P<0.05). There was no significant difference of YM cor and YM med in the lower poles of right kidneys between stage 1 and stage 2 CKD patients (both P>0.05). YM cor[(17.93±3.23) kPa] and YM med [(15.50±1.48) kPa] in patients with crescentic glomerulonephritis were higher than those in patients with focal segmental glomerulosclerosis [(12.71±2.42) kPa, (11.57±2.63) kPa] and mesangial proliferative glomerulonephritis [(12.73±2.04) kPa, (11.48±2.10) kPa](all P<0.05). There was no significant difference of YM cor and YM med between focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis (both P>0.05). YM cor [(16.30±2.63) kPa] and YM med [(15.54±1.59) kPa] of Lee's Ⅳ grade of IgA nephropathy were higher than those of Lee's Ⅲ grade [(13.32±2.70) kPa, (12.57±2.50) kPa](both P<0.05), while the International Study of Kidney Disease in Children grade of purpura nephritis had no significant correlation with YM cor and YM med (both P>0.05). YM cor [(15.41±2.37) kPa] and YM med [(13.82±2.59) kPa] of interstitial fibrosis/tubular atrophy (T1/T2) group of IgA nephropathy mixed with purpura nephritis were significantly higher than those of T0 group's [(12.99±2.40) kPa, (11.79±2.05) kPa] (both P<0.05). Moreover, crescent formation (C1) group had a higher YM cor [(14.21±2.77) kPa] and YM med [(12.80±2.47) kPa] than those in C0 group [(12.73±2.15) kPa, (11.59±1.97) kPa] (both P<0.05), while YM cor and YM med were unrelated to the mesangial hypercellularity (M), endocapillary cellularity (E), segmental sclerosis or adhesion (S) indicators (all P>0.05). In lupus nephritis patients, YM cor ( r=0.744, P=0.035) and YM med ( r=0.728, P=0.009) were favorably linked with the chronic index, but not with the activity index (both P>0.05). Conclusions:Renal interstitial fibrosis/tubular atrophy and crescentic development are connected with YM cor and YM med at the lower pole of the kidney as measured by SWE. SWE can be used to assess the chronic renal lesions in children with CKD in the early and middle stages. It may develop into a new noninvasive way to assess renal pathology.

Objective:To systematically evaluate the distribution characteristics of traditional Chinese medicine (TCM) syndromes in adult influenza patients and to provide a basis for the TCM syndrome differentiation of influenza.Methods:The CNKI, CBM, Wanfang, VIP, PubMed, Embase, Cochrane Library databases were searched to collect cross -sectional studies on the distribution pattern of TCM syndromes in adult patients with influenza. The risk of bias assessment tool for cross -sectional studies developed by the Joanna Briggs Institute (JBI) evidence -based health care center was used to evaluate the literature quality, and the Stata 15.1 software was used to conduct a Meta -analysis of the pooled effect sizes of the included studies. Results:A total of 11 studies with 4 367 influenza patients were included. Quality assessment results of JBI showed that the risk bias was higher in the sample size calculation, and the description of sampling modalities and response rate was unclear. There were 17 influenza syndromes after specification, and a single group rate Meta -analysis was performed of the syndromes with ≥ 50 incident cases showed that there were 9 syndromes with an incidence ≥ 10% and statistical significance, the top 5 syndromes were syndrome of wind and heat invading the defense [ n = 1 583, RATE = 34.3%, 95% confidence interval (95% CI) was 22.2%-46.3%], syndrome of exterior cold and interior heat ( n = 1 122, RATE = 36.1%, 95% CI was 21.2%-51.1%), syndrome of wind -cold fettering the exterior ( n = 860, RATE = 19.4%, 95% CI was 10.7%-28.0%), syndrome of heat and toxin in the lung ( n = 217, RATE = 17.1%, 95% CI was 9.1%-25.0%), and syndrome of disease involving both defense phase and qi phase ( n = 184, RATE = 38.8%, 95% CI was 14.2%-63.5%). The results of the subgroup analysis in different geographical regions showed that the frequency of distribution of syndrome of wind and heat invading the defense and heat and toxin in the lung was higher in the South (RATE: 36.5%, 18.6%) than in the North (RATE: 30.9%, 15.4%), and the frequency of distribution of syndrome of wind -cold fettering the exterior and exterior cold and interior heat in the North (RATE: 23.8%, 40.1%) was higher than that in the South (RATE: 15.7%, 32.3%). Conclusions:There are 9 common TCM syndromes of influenza, including wind and heat invading the defense syndrome, exterior cold and interior heat syndrome, wind -cold fettering the exterior syndrome, heat and toxin in the lung syndrome, disease involving both defense phase and qi phase syndrome, wind and heat complicated by dampnessinvading the surface syndrome, wind and cold complicated by dampnessinvading the surface syndrome, defense phase syndrome and dampness and heatinvading the surface syndrome, which can provide a reference for the TCM syndrome differentiation and treatment of influenza.
