This paper summarizes the clinical experience in treating children adenoid hypertrophy using the "opening the orifices and regulating qi method". It is considered that the pathogenesis of adenoid hypertrophy in children is rooted in dysfunction of zangfu （脏腑） organs， with binding of phlegm and stasis as the branch. Obstruction of the cervical passes and rebellious， chaotic qi flow run through the entire course of the disease. The "opening the orifices and regulating qi method" is proposed， which emphasizes the regulation of the lung， spleen， liver， and stomach. By opening the cervical passes， regulating zangfu organs， and eliminating phlegm and stasis to harmonize the ascent and descent of qi， a comprehensive application of external traditional Chinese medicine （TCM） therapies， such as acupuncture， umbilical moxibustion with medicinals， collateral bloodletting， and sole therapy， is utilized. Addressing both root and branch causes， this approach provides new perspectives for treating children adenoid hypertrophy using external TCM therapies.

Objective To evaluate the effect of Helicobacter pylori(H.pylori)infection on colorectal adenoma(CRA)recurrence after polypectomy and to study other potential prognosis factors associated with CRA recurrence.Methods This single-centered retrospective cohort study included 808 patients with CRA who underwent colonoscopy,polypectomy,and gastroscopy between January 2005 and October 2022.The patients were classified into three groups based on H.pylori infection status:persistently negative(group A,n=626),initially positive but turned negative(group B,n=141),and persistently positive(group C,n=41).The CRA recurrence and high-risk CRA or colorectal cancer(CRC)occurrence were assessed,and potential prognosis factors for recurrence were analyzed.Results During a median follow-up period of 1.6(1.1,2.4)years,the recurrence rate was 56.4%(456/808),including 124 cases(15.3%)of high-risk CRA/CRC[of which 5 cases(0.6%)were CRC]and 332 cases(41.1%)of low-risk CRA.The recurrence rates in the three groups were 55.4%(347/626),60.3%(85/141),and 58.5%(24/41),respectively,with no statistically significant difference(log-rank χ2=0.525,P=0.769).The high-risk CRA/CRC recurrence rates in the three groups were 14.9%(93/626),17.7%(25/141),and 14.6%(6/41),respectively,showing no significant intergroup differences(log-rank χ2=0.340,P=0.844).Multivariate analysis identified increasing age(HR=1.011,95%CI:1.002-1.021,P=0.020)and baseline high-risk CRA(HR=1.428,95%CI:1.183-1.724,P<0.001)as independent prognosis factors for CRA recurrence.Conclusions This study did not find a significant correlation between H.pylori infection and CRA recurrence after polypectomy.Increasing age and baseline high-risk CRA are prognosis factors for CRA recurrence.

Objective:To evaluate the safety and efficacy of combined inflatable mediastinoscopy with laparoscopy guided by the concept of “reduced field and port” during esophagectomy for esophageal cancer.Methods:This is a retrospective cohort study. The clinical data of 497 patients with esophageal squamous cell carcinoma who underwent minimally invasive esophagectomy at the Center of Minimally Invasive Thoracic Surgery, the Second Affiliated Hospital of Naval Medical University, between January 2017 and December 2024 were retrospectively analyzed. There were 416 male and 81 female patients, with an age of (68.3±8.0) years (range: 44 to 89 years). Patients were divided into the traditional video-assisted thoracoscopic surgery group (Group A, n=354) and the combined inflatable mediastinoscopy with laparoscopic surgery group(Group B, n=143) based on the surgical approach. Furthermore, Group B was subdivided into the multiport laparoscopic group (Group B1, n=81) and the single-incision laparoscopic surgery plus one port group (Group B2, n=62). Perioperative indicators and postoperative survival differences were compared between the groups. Inter-group comparisons were performed using the independent sample t-test, χ2 test, or Fisher′s exact probability test. Survival curves were plotted using the Kaplan-Meier method, and the Log-rank test was used to analyze the survival differences between groups. Results:Compared with Group A, Group B demonstrated a significantly shorter operative time ((181.8±11.4) minutes vs. (196.7±8.1)minutes, t=16.09, P<0.01), a lower incidence of postoperative pulmonary complications (8.4% (12/143) vs. 17.8% (63/354), χ2=6.27, P=0.012), lower perioperative mortality (0 vs. 3.1%(11/354), P=0.039), and a shorter postoperative hospital stay ((16.2±2.2)days vs. (18.9±4.1)days, t=8.56, P<0.01). There was no significant difference in the anastomotic leak rate, number of lymph nodes dissected, or intraoperative blood loss between the two groups (all P>0.05). Overall survival time and recurrence-free survival time showed no significant difference between the two groups (all P>0.05). Subgroup analysis revealed no significant differences in perioperative indicators or postoperative complication rates between Group B1 and Group B2. Conclusions:Compared with traditional thoracoscopic combined with laparoscopic surgery, inflatable mediastinoscopy offered advantages in terms of lower postoperative pulmonary complication rates, shorter operative time, reduced postoperative hospital stay, and lower perioperative mortality. The “reduced field and port” concept could further minimize surgical trauma during the transmediastinal approach for esophagectomy while ensuring surgical safety and efficacy.

AIM:This study explores whether curcumin(Cur)promotes mitophagy to attenuate nonalcoholic steatohepatitis(NASH)in mice,as well as the possible molecular mechanisms involved.METHODS:A high-fat and high-cholesterol diet was used to replicate the NASH mouse model.Thirty-two male C57BL/6J mice were randomly divided into normal control(NC)group,high-fat and high-cholesterol model(M)group,M+low-dose Cur(Cur-L)group,and M+high-dose Cur(Cur-H)group,with 8 mice in each group.The weight of 8 mice in each group was recorded weekly.After feeding for 18 weeks,the serum and liver of mice were collected.Serum levels of total cholesterol(TC),triglyceride(TG),low-density lipoprotein(LDL-C),alanine aminotransferase(ALT),aspartate aminotransferase(AST),and tumor necrosis factors-α(TNF-α)were measured.Liver index was calculated,and steatosis,inflammation,and fibrosis of the liver were observed by HE and Masson staining.Western blot analysis was performed to detect the protein expression of mi-tophagy-related protein,TNF-α and α-SMA in the liver.(2)HepG2 cells were treated with oleic acid and cholesterol to replicate the hepatocyte injury model,which was divided into NC group,Cur group,M group,and M+Cur group.Small interfering RNA for PTEN-induced kinase 1(PINK1)knockdown was used to explore the relationship between PINK1-me-diated mitophagy and NASH.Compound C(CC)was used to inhibit AMP-activated protein kinase(AMPK)to explore the effect of the AMPK/silent information regulator 1(Sirt1)pathway on mitophagy.The lipid droplets of HepG2 cells were ob-served by oil red O staining,and the levels of TC,TG,LDL-C,ALT,and AST in cell suspension were detected.RE-SULTS:(1)Compared with M group,treatment with Cur significantly reduced the body weight,liver coefficient,and se-rum levels of TC,TG,LDL-C,ALT,AST,and TNF-α in NASH mice,while the steatosis and fibrosis in the liver were improved(P<0.05).(2)Different concentrations of Cur could increase or decrease the expression of mitophagy-related proteins in HepG2 cells in a concentration gradient.Compared with the M group,Cur reduced lipid droplets and de-creased TC,TG,LDL-C,ALT,and AST levels(P<0.05).(3)Compared with the NC group,the expression levels of mi-tophagy-related proteins in the liver of mice in the M group decreased,and the expression levels of TNF-α and α-SMA pro-teins increased.Different concentrations of Cur intervention promoted the increase of mitophagy-related proteins and the decrease of TNF-α and α-SMA proteins(P<0.05).(4)After Cur intervention,the expression levels of mitophagy-related proteins increased and the expression levels of in TNF-α and α-SMA levels decreased in HepG2 cells induced by oleic acid and cholesterol(P<0.05).(5)Compared with M group,oleic-acidand cholesterol-induced mitophagy function in HepG2 cells was decreased after PINK1 knockdown(P<0.05).After CC inhibited AMPK,Cur increased the expression of p-AMPK(P<0.01),Sirt1(P<0.01),peroxisome proliferator-activated receptor γ coactivator-1α(P>0.05),PINK1(P<0.01)and parkin(P<0.01)proteins to some extent.CONCLUSION:Treatment with Cur attenuates liver injury in NASH mice and reduces lipid accumulation in HepG2 cells induced by oleic acid and cholesterol,and the mechanism may be related to promotion of mitophagy,which may involve the AMPK/Sirt1 signaling pathway.

Objective To investigate the effect of eosinophil(EOS)/neutrophil(NER)in peripheral blood on asthma recurrence in children with bronchial asthma(BA)after treatment.Methods A prospective cohort study was conducted in the study.BA children admitted to the hospital from February 2020 to February 2022 were selected as the research objects.All children were treated regularly and their condition was under con-trol.After a follow-up of 6 months,the recurrence of the children was recorded.EOS/NER,interleukin(IL)-4 and IL-5 of children with and without relapse before treatment and at 1 week of treatment were compared.Lo-gistic regression analysis model was established to test the effect of EOS/NER on the recurrence of asthma in children with BA after treatment.The receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of EOS/NER,IL-4 and IL-5 before treatment for the recurrence risk of BA children after treatment.Results A total of 128 children with BA were included.25 cases recurred after 6 months of follow-up,with a recurrence rate of 19.53%.EOS/NER,IL-4 and IL-5 of BA children after 1 week of treatment were lower than those before treatment(P<0.05).EOS/NER,IL-4 and IL-5 of recurrent children before treat-ment and 1 week after treatment were higher than those of non-recurrent children(P<0.05).There were no statistically significant differences in EOS/NER,IL-4,IL-5 levels between children of different genders,age groups,and treatment regimens before and after 1 week of treatment(P>0.05).Increased EOS/NER,in-creased level of IL-4 and increased level of IL-5 had effect on the recurrence of BA children after treatment and may be risk factors for recurrence(OR>1,P<0.05).The ROC curve showed that area under the curve of EOS/NER before treatment for predicting the recurrence was 0.810(95%CI:0.724-0.896,P<0.001)in BA patients after 6 months of treatment,with moderate predictive value.Conclusion EOS/NER before treat-ment in BA children may be an independent risk factor for recurrence after treatment,and has moderate pre-dictive value for recurrence risk.

AIM:Clopidogrel and aspirin are com-monly used drugs for the secondary prevention of cerebrovascular disease.Due to drug resistance,their preventive effect is often affected.This article explores the clinical value of clopidogrel and aspirin pharmacogenetic genetic testing in the secondary prevention of ischemic stroke.METHODS:220 pa-tients with mild ischemic stroke or TIA admitted to our hospital from 2021.7 to 2022.9 were included and randomly divided into individualized treatment group and clopidogrel conventional treatment group(control group).The patients were followed up for one year to observe stroke recurrence and hemorrhagic events.RESULTS:(1)Compared with the control group,the recurrence rate of ischemic stroke in the individualized treatment group after 1-year follow-up was slightly lower(5.82％vs.7.92％,P＞0.05),the risk of cerebral hemorrhage was simi-lar,but the risk of other occurrences was increased(6.79％vs.0.99％,P＜0.05).(2)COX regression analy-sis showed that ESRS(HR 2.576,95％CI 1.226-5.413,P=0.013)and history of hypertension(HR 5.517,95％CI 1.624-18.737,P=0.006)were associated with recurrence of ischemic stroke,independent of anti-thrombotic regimen(HR 0.918,95％CI 0.291-2.894,P=0.883).CONCLUSION:Aspirin GPIBA,PTGS1,and ITGB3 gene polymorphisms have limited signifi-cance in guiding antiplatelet medication.Selecting aspirin maintenance therapy for clopidogrel CYP2C19*2*3 allele carriers cannot significantly re-duce the risk of recurrence of minor ischemic stroke and may increase other bleeding risks.COX regression analysis shows that ESRS and history of hypertension are independent risk factors for stroke recurrence.
