Detection of poor-water-soluble substances typically requires an organic solvent containing solution,and therefore,the biosensors that can operate in such conditions are highly promising for practical applications.However,most existing biosensors have been developed in aqueous solution and it is hard to work effectively in organic solvent systems.In this work,we uncovered that the G-quadruplex(G4)/hemin DNAzyme(G4HD)could be strongly reactivated by NH4 in organic solvents at concentration up to 30％,and the activity was significantly higher than that in aqueous solutions containing K+.Based on this discovery,a biosensing system was developed for small molecule in 40％methanol by coupling G4HD with our previously identified RNA-cleaving DNAzyme(E3).This system comprised an ATP-activated aptazyme that was made of E3 and a G4HD that was activated by the cleavage product of the aptazyme.By using a manmade pipette tip filter to separate the reaction products,the subsequent colorimetric reaction of the G4HD could be triggered.This biosensing system enabled the visualization of target molecules in organic cosolvents without any other instruments.The activable DNAzyme-cascade sensing system had potential in point-of-care detection of poor-water-soluble pollutants,thereby enhancing the practical values of functional nucleic acid-based biosensors in real-world detection conditions.

Objective To investigate the prevalence and influencing factors of polypoid lesion of gallbladder(PLG)of soldiers stationed on an island.Methods A total of 687 soldiers stationed on an island who underwent annual physical examination from October to December 2020 were selected.They took transabdominal ultrasound and blood biochemical examination,and filled out the questionnaire.There were 62 cases with PLG(PLG group)and 625 cases without PLG(non-PLG group).Age,body mass index(BMI),blood pressure,smoking,eating habits,blood biochemical indexes,and self-rating depression scale(SDS)scores were compared between the two groups.Logistic regression analysis was performed to obtain the independent risk factors for the prevalence of PLG of the soldiers.Results There were significant differences in age,BMI,blood pressure,smoking,irregular diet,total cholesterol(TC),triacylglycerol(TG),low-density lipoprotein cholesterol(LDL-C)and SDS scores between the two groups(all P<0.05).Multivariate Logistic regression analysis showed that age,high BMI,smoking,irregular diet,high TC,high TG,high LDL-C,and high SDS scores were independent risk factors for PLG(all P<0.05).Conclusion There is a high overall prevalence of PLG in the soldiers of this island,which is related to age,high BMI,smoking,irregular diet,high TC,high TG,high LDL-C,and high SDS scores.

Clinically,patients with high-risk cholecystitis are often facing the therapeutic choice of permanent cholecystostomy drainage or high-risk surgery.With the development of percutaneous interventional therapy techniques in recent years,minimally invasive treatment have provided more therapeutic options for these patients.Cryoablation,chemical ablation,and gallbladder-intestine anastomosis are considered as the promising methods for the treatment of cholecystitis.Different combinations of percutaneous cholecystostomy(PC)with sequential cryoablation,chemical ablation,or gallbladder-intestine internal drainage have achieved a high success rate in treating cholecystitis,thus,providing patients with an option of non-surgical resection.This article aims to make a comprehensive review about various percutaneous treatment methods for cholecystitis so as to provide useful references for clinical practice.

Objective To study the effects of Shugan Jieyu capsules on the cardiac function and state of mind of chronic heart failure(CHF)patients with anxiety and depression.Methods Ninety-four CHF patients with anxiety and depression were randomly divided into the Shugan Jieyu capsule treatment group and mental therapy control group.Self-rating depression Scale(SDS),self-rating anxiety scale(SAS),left ventricular ejection fraction(LVEF),N-terminal pro-B-type natriuretic peptide(NT-proBNP),the 6-minute walking test(6MWT),hemoglobin(Hb),interleukin-6(IL-6),albumin(ALB)and high-sensitivity c-reactive protein(hs-CRP)were compared between the two groups before and after treatment using t-tests and chi-square tests in order to find out about the efficacy of Shugan Jieyu capsules in CHF patients with anxiety and depression.Results After 8 weeks of treatment,SDS,SAS,NT-proBNP,hs-CRP and IL-6 were all significantly lower,especially in the treatment group,while LVEF,6MWT,Hb and ALB were significantly higher or longer,particularly in the treatment group.Conclusion Shugan Jieyu capsules can effectively alleviate anxiety and depression in CHF patients,improve the cardiac function and nutritional status,and mitigate inflammation.

Objective:To analyze the effect of thoracoscopic subsegmental resection under the guidance of three dimensional(3D)computed tomography bronchography and angiography(3D-CTBA)for resection of pulmonary nodules.Methods:A total of 40 patients who underwent 3D-CTBA-guided thoracoscopic subsegmental resection in Nanjing Jiangbei Hospital of Nantong University from January 2020 to October 2021 were selected as the observation group,and other 35 patients who underwent 3D-CTBA-guided thoracoscopic pulmonary segmentectomy were selected as the control group.The intraoperative and postoperative conditions,and the incidence of postoperative complications of the two groups were observed.Results:The differences of amount of intraoperative blood loss,average margin width,postoperative drainage,retention time of drainage tube between observation group and control group were significant(t=8.644,2.862,10.03,3.277,P<0.05),respectively.The numbers of occurring postoperative chest leakage,pulmonary infection and hemoptysis in observation group and control group were respectively"3,1,1"and"2,1,2".The incidences of complications of two groups were respectively 12.5%and 14.29%,without statistical significance between the two groups(P>0.05).Conclusion:3D-CTBA-guided thoracoscopic subsegmental resection can shorten the operation time,and reduce intraoperative blood loss and the injury of tracheas and blood vessels,and improve the postoperative recovery of patients.

Objective To investigate the expression levels of serum high-mobility group box 1(HMGB1),soluble CD163(sCD163),and prostaglandin E2(PGE2)in patients with hepatitis B virus-related chronic-on-acute liver failure(HBV-ACLF),and to evaluate the value of the three indicators used alone or in combination in predicting prognosis.Methods A total of 76 patients with HBV-ACLF who were hospitalized in Department of Infectious Diseases,The First Affiliated Hospital of Xinxiang Medical University,from July 1,2022 to September 30,2023 were enrolled,and according to the 28-day prognosis,they were divided into survival group with 48 patients and death group with 28 patients.General data were collected,Model for End-Stage Liver Disease(MELD)score was calculated,and ELISA was used to measure the serum levels of HMGB1,sCD163,and PGE2.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.The Spearman rank correlation test was used to analyze the correlation of HMGB1,sCD163,and PGE2 with MELD score;the receiver operating characteristic(ROC)curve was used to analyze the value of HMGB1,sCD163,and PGE2 used alone or in combination in predicting the prognosis of HBV-ACLF patients.Results There were significant differences between the two groups in total bilirubin,white blood cell count,the percentage of neutrophils,procalcitonin,serum amyloid A,interleukin-6,serum sodium,and serum creatinine(all P＜0.05).Compared with the survival group,the death group had significantly higher serum levels of HMGB1(Z=-2.997,P=0.003)and sCD163(Z=-2.972,P=0.003),a significantly higher MELD score(t=-6.997,P＜0.001),and a significantly lower serum level of PGE2(Z=-4.909,P＜0.001).The Spearman rank correlation test showed that HMGB1 and sCD163 were positively correlated with MELD score(r=0.431 and 0.319,both P＜0.05),while PGE2 was negatively correlated with MELD score(r=-0.412,P＜0.05).The ROC curve analysis showed that HMGB1,sCD163,and PGE2 used alone had an area under the ROC curve(AUC)of 0.717,0.716,and 0.856,respectively,while the combination of the three indicators had the highest predictive value,with an AUC of 0.930,a sensitivity of 0.778,and a specificity of 0.920.Conclusion Serum HMGB1,sCD163,and PGE2 used alone or in combination have a good reference value in predicting the prognosis of HBV-ACLF patients,and the combination of the three indicators has the highest predictive value,which holds promise for further observation and research.

Objective To explore the molecular mechanism of miR-125b promoting invasion,metastasis and epithelial-mesenchymal transition(EMT)of gastric cancer cells.Methods The expression of miR-125b in gastric cancer and its adjacent tissues was studied by qRT-PCR.After upregulating or downregulating miR-125b in gastric cancer cells,the protein expressions of DKK3 and SERPINA4 were detected by Western blotting.Dual luciferase reporting assay was used to verify whether miR-125b can target DKK3 and SERPINA4.MKN45 cells were co-transfected with miR-125b inhibitor and target gene siRNA.Migration and invasion experiments were conducted to explore whether miR-125b can regulate the biological function of MKN45 cells through DKK3 and SERPINA4.Then,the regulatory mechanism of SRF on miR-125b was investigated.Finally,by in vivo experiments,the expression of SRF in gastric cancer cells was upregulated or downregulated by lentivirus transfection;the number of lung metastases in nude mice was detected to explore the effect of SRF on gastric cancer cell metastasis.Results In this study,the expression of miR-125b increased in gastric cancer tissues,which was correlated with clinical stage and lymph node metastasis.Dual luciferase reporting experiments showed that DKK3 and SERPINA4 were the direct targets of miR-125b in gastric cancer cells,and could activate the Wnt/β-catenin signaling pathway,thereby promoting the transcription process of EMT-related transcription factors Twist1 and Slug,inducing the occurrence of EMT,and promoting the metastasis of gastric cancer.In vitro and in vivo experiments confirmed that SRF promoted the invasion and metastasis of gastric cancer cells by positively regulating the expression of miR-125b.Conclusion Taken together,SRF/miR-125b axis promotes the EMT and metastasis of gastric cancer cells,and these regulators represent new potential therapeutic targets or biomarkers for gastric cancer.

Objective:To examine the early to mid-term clinical outcomes of aortic valve repair in patients with bicuspid aortic insufficiency.Methods:This is a retrospective cohort study. The clinical data of 124 patients with BAV insufficiency who underwent aortic valve repair from January 2017 to June 2023 in the Department of Cardiovascular Surgery at Fuwai Hospital were analyzed retrospectively. There were 117 males and 7 females with an age of (38.1±12.7) years (range: 14 to 65 years). Depending on whether the aortic sinus was replaced or not, surgical approaches were divided into valve sparing root replacement (reimplantation, remodeling, modified remodeling) and isolated aortic valve repair (annuloplasty, isolated aortic valve leaflet repair). Perioperative and follow-up data were collected. Kaplan-Meier method was used to plot the curves of survival rate, free recurrence rate of massive aortic valve insufficiency and free re-operation rate, and Log-rank test was used for comparison between groups.Results:Among the surgeries, there were 47 cases of reimplantation, 8 cases of remodeling, 8 cases of modified remodeling, 48 cases of aortic annuloplasty (external annuloplasty in 22 cases, CV-0 annuloplasty in 26 cases), and 13 cases of isolated leaflet repair. Leaflet plication was the most used leaflet repair technique, used in 103 patients. The cardiopulmonary bypass time was (133.7±56.9) minutes (range: 48 to 461 minutes), and aortic cross-clamp time was (103.8±47.8) minutes (range: 25 to 306 minutes), with no surgical mortality. All patients underwent outpatient or telephone follow-up. The cumulative follow-up time was 340.3 person-years and the mean follow-up time was ( M (IQR)) 34.0 (25.5) months (range: 3 to 76 months). The 5-year survival rate was 98.4%, the 5-year freedom from significant insufficiency rate was 93.4% and the 5-year freedom from aortic valve reoperation rate was 95.6%. The subgroup analysis revealed a significantly better freedom from the significant insufficiency rate in the aortic valve annular reduction group compared to the non-reduction group ( P<0.01). Conclusions:Aortic valve repair in patients with bicuspid aortic insufficiency could obtain steady early to mid-term outcomes. Aortic annuloplasty can reduce the risk of recurrent aortic valve insufficiency in patients undergoing aortic repair.
