Objective To investigate the efficacy of preoperative nebulized indocyanine green (ICG)-assisted thoracoscopic anatomical lesion resection (TALR) in treating pediatric congenital pulmonary airway malformation (CPAM). Methods A retrospective analysis was conducted on clinical data of 45 children with CPAM who underwent thoracoscopic surgery at the Third Affiliated Hospital of Zhengzhou University between June 2023 and March 2025. The patients were divided into an ICG group (preoperative nebulized ICG 0.5 mg/kg+TALR) and a non-ICG group (TALR under white light), with perioperative and postoperative recovery parameters compared between groups. Results A total of 45 children [22 males, 23 females; median age 7.4 (1.1-75.0) months] were enrolled. The ICG group (n=22) and non-ICG group (n=23) both achieved uneventful recoveries. Compared to the non-ICG group, the ICG group demonstrated significantly shorter surgical duration [91.3 (38.0-144.0) min vs. 100.0 (50.0-175.0) min, P=0.032], reduced intraoperative blood loss [3.0 (2.0-10.0) mL vs. 5.0 (1.0-10.0) mL, P=0.049], shorter postoperative drainage duration [2.7 (1.9-3.9) d vs. 3.4 (1.8-19.9) d, P=0.003], and shortened hospital stay [4.6 (2.9-9.8) d vs. 5.0 (3.9-21.5) d, P=0.013]. Residual lesions occurred in 2 patients from the non-ICG group but none in the ICG group. Intragroup comparisons revealed significant improvements in ratio of time to peak tidal expiratory flow to expiratory time, ratio of volume to peak tidal expiratory flow to expiratory volume, and tidal volume per kilogram after surgery in both groups (P<0.05), though intergroup differences showed no statistical significance (P>0.05). Conclusion Preoperative nebulized ICG administration facilitates lesion identification in CPAM, reduces technical difficulty of TALR, enhances therapeutic outcomes, and provides valuable assistance for performing TALR procedures.

Objective:To investigate the comorbidity rate of chronic diseases and prevalence of depressive symptoms among the middle-aged and elderly population,and explore the association between comorbidity with-chronic disease and depressive symptoms in middle-aged and older people.Methods:A cross-sectional study was conducted in Shandong Province.A total of 9 535 middle-aged and older people aged 45 years and over were recrui-ted.General information questionnaire,the chronic disease information questionnaire and Patient Health Question-naire were used for face-to-face interview to screen symptoms and collect information.Univariate analysis and mult-ivariate logistic regression analysis were employed to explore the association between comorbidity with chronic dis-ease and depressive symptoms.Results:The prevalence of depressive symptoms among middle-aged and older peo-ple was 8.7％,while among those with comorbid chronic diseases,the prevalence of depressive symptoms was 29.6％.Respectively,demonstrating an increasing trend with the number of chronic diseases(P＜0.001).Multiva-riate analysis revealed that comorbid chronic disease(OR=1.47,95％CI:1.22-1.78)were risk factors of depres-sive symptoms.Conclusion:Middle-aged and older people with multiple chronic conditions are more likely to be di-agnosed with depressive symptoms,and the detection rate of these symptoms increases with the number of comorbid chronic conditions.Therefore,it is recommended to strengthen mental health interventions for those with multiple chronic conditions.

ObjectiveTo investigate the safety and efficacy of endoscopic retrograde cholangiopancreatography （ERCP） combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in the treatment of difficult choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 12 patients with difficult choledocholithiasis who underwent ERCP and electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in Department of Gastroenterology， Jilin People’s Hospital， from May to November 2022. The clinical effect of lithotripsy and lithotomy was observed， and postoperative complications and time of surgical operation were assessed. ResultsAmong the 12 patients， 11 （91.67%） were successfully treated by electrohydraulic lithotripsy under direct view， 9 （75.00%） achieved first-attempt success in lithotripsy， and 11 （91.67%） had complete removal of calculi； 1 patient was found to have stenosis of the bile ducts caused by multiple biliary tract surgeries， and grade Ⅱ intrahepatic bile duct stones above the sites of stenosis were removed under direct view， but there were still residues of grade Ⅲ intrahepatic bile duct stones， which led to the fact that complete calculus removal was not achieved. The mean time of ERCP operation was 91.3±26.2 minutes， including a time of 41.8±22.2 minutes for energy lithotripsy. There were 2 cases of postoperative biliary tract infection which were improved after anti-infective therapy， 2 cases of hyperamylasemia which were not given special treatment， and 3 cases of mild pancreatitis which were improved after symptomatic medication， and there were no complications such as bleeding and perforation. ConclusionERCP combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system is safe， effective， and feasible in the treatment of difficult choledocholithiasis.

ObjectiveTo discuss the effects of Cistanches Herba phenylethanoid glycosides （CHPhGs） on the intestinal mucosal barrier and gut microbiota in alcoholic liver disease （ALD） mice were discussed. MethodThe 36 C57BL/6N female mice were randomly divided normal group， normal group of CHPhGs， model group， and low， medium， and high-dose groups （175， 350， 700 mg·kg^-1） of CHPhGs， with six mice in each group. The ALD mouse model was built using Lieber-Decarli alcohol liquid feed. The normal group and low， medium， and high-dose groups of CHPhGs were given CHPhGs by gavage daily. Serum aspartate aminotransferase aminotransferase （ALT）， alanine aminotransferase （AST）， triglycerides （TG）， and total cholesterol （TC） levels were detected by an automatic biochemical analyzer. Serum tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， lipopolysaccharide （LPS）， lipopolysaccharide-binding protein （LBP）， D-lactic acid （D-LA）， diamine oxidase （DAO）， and LBP of liver were detected by enzyme-linked immunosorbent assay （ELISA）. The levels of TG and TC in the liver were detected by colorimetry. Liver tissue was treated by oil red O and hematoxylin-eosin （HE） staining. The microstructure of jejunum epithelial cells was observed by electron microscope. Jejunum and colon were treated by HE staining and alcian blue-periodate-scheff (AB-PAS) staining staining， and mucin 2 （Muc2） was treated by immunohistochemistry. The intestinal contents of the normal group， normal group of CHPhGs， model group， and high-dose group of CHPhGs were collected and sequenced. ResultThe ALD model was established successfully. Compared with the normal group， the levels of serum ALT， AST， and TG， as well as the levels of liver TG and TC in the model group were significantly increased （P<0.05）. Histopathology showed that compared with the normal group， the liver cells in the model group showed obvious steatosis. Compared with the model group， the levels of serum TG and liver TG and TC in the low， medium， and high-dose groups of CHPhGs decreased significantly （P<0.05）. The serum ALT， AST， TNF-α， IL-1β， LPS， and LBP in the high-dose group of CHPhGs were also significantly decreased （P<0.05）. The number of liver cells with steatosis in the high-dose group of CHPhGs was significantly reduced， and the microvilli structure of jejunum epithelial cells was basically intact. The expression of Muc2 was reduced in the colon， and the gut microbiota of the high-dose group of CHPhGs changed significantly （P<0.05）. Compared with the normal group， the Allobaculum was significantly up-regulated in the model group （P<0.05）. Compared with the model group， the abundance of Akkermansia in the high-dose group of CHPhGs was significantly increased （P<0.01）. The abundance of Akkermansia was negatively correlated with that of Allobaculum （r=-0.701， P<0.01）. ConclusionCHPhGs can reduce the intestinal barrier injury caused by ALD， which may play a protective role by regulating the abundance and structure of Akkermansia and Allobaculum and affecting the homeostasis of intestinal mucus.

Objective To explore the relationship between single nucleotide polymorphisms at the rs2231142(G/T)locus of the ABCG2 gene and susceptibility to hyperuricemia.Methods A total of 865 male study subjects were collected from the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University,the People's Hospital of Xinjiang Uygur Autonomous Region,and the First Affiliated Hospital of Xinjiang Medical University and other hospitals from 2018 to 2020,their blood samples were collected,and they were divided into hyperuricemia group(n=367)and healthy control group(n=498)according to blood uric acid levels.Multiplex fluorescent polymerase chain reaction(PCR)was used to detect the genotype of the rs2231142(G/T)locus of the ABCG2gene and to ob-serve the gene polymorphism in the two groups.The effect of this sequence on luciferase expression activity was confirmed by dual lucifer-ase reporter gene experiment.Results The values of uric acid,body mass index,glucose,creatinine,triglycerides,diastolic blood pres-sure,high density lipoprotein and low density lipoprotein in the hyperuricemia group were higher than those in the control group,and the differences were statistically significant(P＜0.05).The gene rs2231142(G/T)loci met the HWE equilibrium test of the two groups(P＞0.05),indicating that the locus is representative of the population.There were statistically significant differences in the distribution frequencies of GG,GT,and TT genotypes in the hyperuricemia group and healthy control group(x2=17.146,P＜0.001),and there were also statistically significant differences in the distribution frequencies of alleles G and T between the two groups(x2=19.115,P＜0.001).TT genotypes were expressed as risk factors for hyperuricemia in different genetic models(additive model OR=2.302,95％CI:1.472-3.603;explicit model OR=1.689,95％Cl:1.283-2.210;recessive model OR=1.867,95％CI:1.221-2.874).The differences in uric acid,glucose and triglycerides among the different genotype subgroups were statistically significant(P＜0.05).The results of the pair comparison showed that there were significant differences in uric acid,glucose and triglyceride levels between the G/T group and G/G group,T/T group and G/G group(P＜0.05).The level of uric acid in T/T group was the highest,the level of glucose and triglyceride in G/G group was the highest.The results of double luciferase activity assay showed that rs2231142(G/T)had promoter function;and the expression level of the recombinant plasmid luciferase reporter gene containing the G allele was higher than that of the re-combinant plasmid containing the T allele by 1.120 fold(P=0.012).Conclusion There is an association between single nucleotide polymorphisms at the rs2231142(G/T)locus of the ABCG2gene and susceptibility to hyperuricemia,and the T allele may be a risk factor for hyperuricemia.

Objective To investigate the technique and dosage selection of indocyanine green(ICG)fluorescence staining in laparoscopic anatomical hemihepatectomy.Methods A retrospective cross-sectional study was conducted.The clinical date of the patients who underwent laparoscopic anatomical hemihepatectomy in the Cancer Hospital of the Chinese Academy of Medical Sciences from October 2020 to October 2023 was collected and analyzed,and the management of the Glissonean pedicle,the method and effect of ICG fluorescence staining during the operation,the dose of ICG injection,and the postoperative recovery were analyzed.Results A total of 91 laparoscopic anatomical hemihepatectomies were enrolled in this study,including 28 right hemihepatectomies and 63 left hemihepatectomies.The Glissonean pedicle was dissected intra-sheath in 9 cases and extra-sheath in 82 cases.ICG fluorescence staining was all performed using the negative staining method,of which 69 cases(75.8%)were successfully stained.The success rate of staining in the extra-sheath dissection and low-dose ICG group was higher than that in the intra-sheath dissection and high-dose ICG group.The average operation time was(168.5±32.2)minutes,the intraoperative bleeding volume was(152.4±56.3)ml,and the intraoperative blood transfusion rate was 6.6%(6/91),the average postoperative hospital stay was(8.5±2.6)days.One case was converted to laparotomy due to exophytic growth of the tumor compressing the Glissonean pedicle.Four cases had Clavien-Dindo Ⅰ-Ⅱ complications,all of which improved after treatment.There were 3 cases of grade Ⅲa complications,all of which were caused by bile leakage and abdominal cavity infection.They were cured by puncture and drainage.And there were no serious complications above grade Ⅲb.Conclusions In laparoscopic anatomical hemihepatectomy,the ICG fluorescence staining method was recommended to use the negative staining method of the extra-sheath dissection of the Glissonean pedicle,and a lower dose of ICG could help to increase the success rate of fluorescence staining.

Objective:To explore the effect of triglyceride glucose(TyG) index, single nucleotide polymorphism of Toll-like receptor 4(TLR4) and NOD-like receptor thermal protein domain associated protein 3(NLRP3) genes, and its interaction on the risk of gout.Methods:A total of 315 male patients with gout and 499 men for health checkup at the same period were selected. General data were collected through questionnaires, and peripheral venous blood was collected for biochemical test. Three single nucleotide polymorphisms(SNPs) of NLRP3 and TLR4 were detected with multiplex ligase assay reaction, and logistic regression analysis was applied to compare the correlation between NLRP3 and TLR4 alleles and gout risk. The interaction of SNP and TyG index with gout was analyzed by generalized multi-factor dimensionality reduction(GMDR) model and logistic regression.Results:After adjusting for smoking, drinking, and other factors, the risk of gout increased by 61.1% for each standard deviation increase in TyG index. CC genotypes of rs10754558, rs10759932, and rs7525979 were high risk genotypes of gout in Han ethnicity. GMDR results showed significant differences in the interaction models of rs10754558-TyG index, rs7525979-TyG index, and rs10759932-TyG index between control group and gout group( P<0.05), suggesting an interaction between the three genotypes of SNPs selected and TyG index. Stratified analysis of the three selected SNPs and TyG index showed that after adjusting for age, smoking, and other factors, the high TyG index patients carrying C/C or C/G genotype at rs10754558 displayed an increased risk of gout compared with those carrying GG genotype and low TyG index( OR=2.127, P<0.05). Conclusion:The CC genotypes of rs10754558, rs10759932, and rs7525979 are high risk genotypes for gout in Han ethnicity. The interaction between rs10754558 and TyG index may increase the risk of gout development.

Objective:To analyze the clinical value of noninvasive pressure strain loop (PSL) in assessing left ventricular myocardial work in patients with essential hypertension.Methods:In this cross-sectional study, 66 patients with essential hypertension who were admitted to the Affiliated Hospital of Yangzhou University from August to December 2020 were continuously enrolled. According to left ventricular mass index (LVMI) >95 g/m 2 in women and >115 g/m 2 in men,≤95 g/m 2 in women and ≤115 g/m 2 in men, the 66 patients were divided into left ventricular hypertrophy (LVH) group (14 cases) and non-left ventricular hypertrophy (NLVH) group (52 cases). Furthermore, the NLVH group was divided into a mild group (30 cases) and a moderate/severe group (22 cases) according to the systolic blood pressure of 140~159 mmHg (1 mmHg=0.133 kPa) and ≥160 mmHg. Another 25 healthy adults who underwent physical examination during the same period were included as healthy control group. The height, weight and blood pressure were measured in all the subjects, and routine echocardiography and speckle tracking imaging analysis were performed. PSL results were obtained by combining the results of speckle tracking imaging analysis with systolic blood pressure. The differences of general clinical data, basic parameters of two-dimensional ultrasound and myocardial work parameters of PSL (global work index, global effective work, global wasted work, and global work efficiency) were compared among the groups, and the clinical value of PSL in assessing left ventricular myocardial work in patients with essential hypertension was analyzed. Results:There was no significant difference in left ventricular ejection fraction among all groups (all P>0.05). The global work index of moderate/severe NLVH group was significantly higher than that of mild NLVH group, LVH group and healthy control group [(2 630±231) vs (2 254±179), (1 847±261), (1 724±209) mmHg%]. The global effective work of moderate/severe NLVH group was significantly higher than that of LVH group and healthy control group [(2 965±261) vs (2 330±258) and (2 121±163) mmHg%] (all P<0.05). The global wasted work of LVH group was significantly higher than that of moderate/severe NLVH group, mild NLVH group and healthy control group [(248±107) vs (141±57), (116±57), (83±58) mmHg%] (all P<0.05). The global work efficiency was significantly lower than that of moderate/severe NLVH group, mild NLVH group and healthy control group (89.1%±3.9% vs 94.3%±1.9%, 95.0%±1.8%, 95.8%±2.3%) (all P<0.05). With the increase of blood pressure, the PSL decreased in the LVH group and increased in the other three groups. The bull′s eye diagram of myocardial work in the healthy control group was uniform green (normal effective work area), red began to appear in the mild NLVH group (high intensity myocardial work area), red area increased in the moderate/severe NLVH group, and blue appeared in the LVH group (ineffective work area). Conclusions:PSL has good clinical value in assessing left ventricular myocardial work in patients with primary hypertension. The parameters derived from PSL data can sensitively identify impaired systolic function in individuals with normal left ventricular ejection fraction.
