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.

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.

Stent entrapment is a rare complication of percutaneous coronary intervention.In recent years,with the development of distal radial artery puncture technology,the rare complications related to distal radial artery have been gradually understood.This article describes a patient who underwent coronary intervention through a distal radial approach,and the stent was dislodged and trapped in the far radial artery.The patient came to our hospital for stent implantation because of acute extensive anterolateral myocardial infarction.During the intervention,the balloon could not be filled when the stent was released from the left anterior descending artery,and the retracting stent could not be used to remove the guide catheter.The stent was dislodged and embedded in the distal vessel.The sheath was inserted through the proximal radial reverse puncture,and the stent was captured with a snare and removed.

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 investigate the effect of active muscle response on mechanical responses and injuries of human neck under high Gx loading.Methods A refined finite element model of the head and neck with active muscle response was established and validated based on the existing post-crash volunteer experiments.The effects of active muscle action on the kinematic and biomechanical responses of the neck were investigated under different G-value loads and at each tilting angle using this model.Results The stress distribution of vertebrae under high Gx load was dispersed from C4-7 to the whole vertebrae,and the active muscle action reduced the stress change,and the effect was significant under 8 G acceleration,which reduced the peak vertebral bone stress by 23.6％and 11.6％,and the peak intervertebral disc stress by 42.3％and 63.4％under 8 G and 10 G conditions,respectively.The maximum stress difference of 34.3 MPa was achieved by the active muscle action at 15° backward tilting.Conclusions The neck showed better stability by the active muscle action under the impact of high Gx loading.At different tilting angles,the active muscle action was more obvious in the backward tilting posture compared with the forward tilting and upright seated postures,and the backward tilting posture was safer to meet the impact when the same active muscle action was applied.The results can provide a reference for the subsequent studies related to the neck injury.

Objective To investigate the effectiveness and safety of biological patch in minimally invasive inguinal hernia surgery.Methods From July 2019 to July 2021,100 inguinal hernia patients were divided into two groups based on the actual type of patch received.Biological patch was used in the experimental group(50 cases),and polypropylene patch was used in the control group(50 cases).The operation method was laparoscopic transabdominal preperitoneal(TAPP)hernia repair.Operating time,bleeding volume during operation,hospital stay after operation,hernia recurrence rate,incision infection rate,patch infection rate,and complication rate were compared between the two groups.Results Two groups of patients had no recurrence of hernia within 3 years after surgery,and didn't experience incision infection or patch infection after surgery.There were no significant differences in operating time,bleeding volume during operation,hospital stay after operation,seroma rate and chronic pain rate between the two groups(P>0.05).The incidence rate of foreign body sensation in the control group was higher than that in the experimental group,with statistical difference(P<0.05).Conclusion In conclusion,biological patch is safe and effective in laparoscopic TAPP hernia repair,and can reduce the incidence of postoperative foreign body sensation,providing a new option for laparoscopic inguinal hernia repair.

Objective To analyze the medication rules of Chinese herbal concentrated-granule for the treatment of hypertension nationwide using data mining and knowledge graph methods,thus to provide evidence for expanding its application in treating hypertension.Methods From January 2022 to March 2023,Chinese herbal concentrated-granule prescriptions for hypertension prescribed by traditional Chinese medicine experts nationwide were collected.Microsoft Excel was used to analyze the frequency,properties and flavors,meridian tropism,and efficacy categories of the medicinals.Hierarchical clustering was applied for cluster analysis,and the Neo4j graph database was utilized to construct an information knowledge graph illustrating the relationships between regions and medicinals.Results A total of 2 600 Chinese herbal concentrated-granule prescriptions were included,involving 370 medicinals.The top six frequently-used medicinals were Poria(Fuling),Glycyrrhizae Radix et Rhizoma(Gancao),Atractylodis Macrocephalae Rhizoma(Baizhu),Citri Reticulatae Pericarpium(Chenpi),Paeoniae Radix Alba(Baishao),and Angelicae Sinensis Radix(Danggui).The properties of the medicinals were mainly warm and mild,and their flavors were usually sweet,pungent,and bitter.The medicinals frequently have the meridian tropism of the spleen,lung,and liver meridians.Hierarchical clustering yielded seven clusters.The information knowledge graph of region-medicinals relationships revealed that medicinals used in five or more regions were Baishao,Baizhu,Chenpi,Pinelliae Rhizoma(Banxia),Fuling,Gastrodiae Rhizoma(Tianma),Bupleuri Radix(Chaihu),Chuanxiong Rhizoma(Chuanxiong),Salviae Miltiorrhizae Radix et Rhizoma(Danshen),Danggui,Gancao,and Astragali Radix(Huangqi).Conclusion Chinese herbal concentrated-granule for hypertension usually consist of tonifying medicinals,with sweet and warm properties,and having the meridian tropism of the spleen meridian.And the medicinals composed of the prescriptions often have the actions of calming the liver and suppressing yang,strengthening the spleen and removing dampness,and nourishing the liver and kidney.

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.

Objective:To construct an infectious clone of a Chinese HIV-1 CRF01_AE epidemic strain with strong replication capacity，and comprehensively identify its viral phenotype and replication capacity.Methods:Using the CRF01_AE clinical isolate GX2005002，which was previously isolated from whole blood of an HIV-1-infected individual in China by our laboratory，as the parental strain，the full-length genome of the virus（9.7 kb）was divided into 5' half fragment（5.1 kb）and 3' half fragment（4.6 kb）for amplification. The proviral DNA was used as a template to amplify the virus genome，which was then ligated into the eukaryotic expression vector pEASY-T1. The consistency of its sequence with the parental strain sequence was identified through full-length genome sequencing and phylogenetic analysis. The replication capacity，syncytium inducibility，and cell tropism were experimentally identified to determine its phenotypic consistency with the parental strain.Results:An infectious clone of the CRF01_AE strain was successfully constructed，and its genome sequence exhibited high consistency with the sequence of the parental strain. By transfecting target cells，a derivative virus with infectious activity and replication capability was successfully rescued. The derived virus maintained phenotypic characteristics consistent with the parental strain，such as cell tropism and syncytium inducibility.Conclusion:This study successfully constructed an infectious clone of a Chinese HIV-1 CRF01_AE epidemic strain with clear background and distinct phenotype. The genomic sequence and viral phenotypic characteristics of the derived virus are basically consistent with the parental strain，providing strong representation of the original isolate and serving as a powerful tool for research on the correlation between the genetic characteristics，viral phenotype，and pathogenicity of HIV-1 CRF01_AE strains.
