Background: Diabetic kidney disease (DKD) is recognized as a significant complication of diabetes mellitus and categorized into glomerular DKDs and tubular DKDs, each governed by distinct pathological mechanisms and biomarkers. Methods: Through the identification of common features observed in glomerular and tubular lesions in DKD, numerous differentially expressed gene were identified by the machine learning, single-cell transcriptome and mendelian randomization. Results: The diagnostic markers versican (VCAN) was identified, offering supplementary options for clinical diagnosis. VCAN significantly highly expressed in glomerular parietal epithelial cell and proximal convoluted tubular cell. It was mainly involved in the up-regulation of immune genes and infiltration of immune cells like mast cell. Mendelian randomization analysis confirmed that serum VCAN protein levels were a risky factor for DKD, while there was no reverse association. It exhibited the good diagnostic potential for estimated glomerular filtration rate and proteinuria in DKD. Conclusion VCAN showed the prospects into DKD pathology and clinical indicator.

Based on the discussion of "eight weak areas" in The Inner Canon of Yellow Emperor （《黄帝内经》）， combined with the typical rash manifestations of atopic dermatitis， it is believed that atopic dermatitis is mostly deficiency-excess complex， and that pathogens intruding eight weak areas are the core of its pathogenesis. The external cause is exterior deficiencies， with heat， wind， dampness and other pathogenic qi attacking. The heart， lungs， kidneys out of balance， and excess pathogen are the internal cause， in which fire constraint and excessive heat are the basis of the disease， the wind invading leads to the progress of the changes， dampness obstructing channels and colla-terals make the condition persistent. Internal and external pathogens combination and retention result to the course of the disease lingering and difficult to cure. The internal treatment is to regulate zang-fu organs， and the formula could use self-prescribed modified Qingrun Tongluo Decoction （清润通络汤）， clearing heart and reducing fire in order to clear the heat and cool the blood， moistening lungs and generating metal to consolidate the exterior and dispel the wind， and nourishing kidneys and draining water to dispel the dampness and activate the collaterals. The external treatment applies maceration， fire acupuncture， wrapping to dredge the eight weak areas and regulate qi and blood in channel， so as to expel pathogens.

Assessment is an indispensable and critical activity in the educational process. In the recent decades, with the birth and development of competence-based educational paradigm, the rationale behind assessment is shifting from "assessment of learning" to "assessment for learning". Workplace-based assessment (WPBA), which aims to improve the quality of both learning and teaching through assessment in real workplace circumstances, is a set of assessment tools that conforms to the new concepts of medical education. In this article, with the purpose to promote the application of WPBA and thus enhance the quality of dental education in our country, a thorough discussion is performed regarding the core principles, tools, advantages of WPBA as well as attentions that should be noted when applying WPBA. It is recommended to establish a longitudinal assessment system which employs various WPBA tools and assesses the development of students' competencies through the whole educational process. Such a dynamic assessment system may be helpful to provide all-rounded and competent dental talents who can eventually benefit the society.

Aim To evaluate the effectiveness and safety of remimazolam tosylate for administering general anesthesia in morbidly obese patients.Methods This clinical trial was conducted at a single center from De-cember 2021 to October 2023.It assessed 108 morbid-ly obese patients(body mass index,BMI≥40)who underwent laparoscopic sleeve gastrectomy.Patients were randomly assigned to either the remimazaolam group(Group R)or the propofol group(Group P)for general anesthesia induction and maintenance.The primary outcome was to compare the incidence of ad-verse events and postoperative recovery characteristics between the two groups.Results During induction pe-riod,the incidence of adverse events was higher in group P,including hypotension(P＜0.01),hypox-emia(P＜0.05),bradycardia(P＜0.01),and in-creased vasopressor requirement(P＜0.05).The time to loss of consciousness and BIS falling to 60 was shor-ter in group P than in group R(P＜0.01).There were no statistically significant differences between the two groups in terms of postoperative quality of recovery(QoR-40 score),24-hour postoperative pain visual an-alogue scale(VAS)scores and morphine consump-tion.In conclusion,remimazolam tosylate,utilized for anesthesia induction in morbidly obese patients,signif-icantly reduced hypotension and hypoxemia compared to propofol,while it could also maintain similar postop-erative recovery quality.Conclusions Remimazolam is effective in reducing the incidence of hypotension and hypoxaemia during the induction period of general anaesthesia in morbidly obese patients and it is compa-rable to propofol in terms of quality of postoperative re-covery.

Acute mitral regurgitation(MR)in the setting of myocardial infarction(MI)may be the result of papillary muscle rupture(PMR).The clinical presentation can be catastrophic,with refractory cardiogenic shock.This condition is associated with high morbidity and mortality.Transcatheter edge-to-edge repair(TEER)has become increasingly common in treating severe mitral regurgitation.This case details a successful TEER is feasible and safe in patients with acute MR following MI.TEER is an emerging treatment option in this clinical scenario that should be taken into consideration.

Type Ⅵ secretion system(T6SS)is a lethal weapon that releases effectors in direct contact to kill eukaryotic predators or prokaryotic competitors.T6SS is of great significance in bacterial environmental adaptability,pathogenicity,and gene horizontal transfer.T6SS has been identified in about 25％of Gram-negative bacteria.Because of its widespread existence,T6SS is considered the key factor of ecological competition.T6SS effectors exerting biological functions have high diversity and do not have conserved sequences,and the regulatory mechanisms involved are complex.Therefore,it is a hot and difficult topic in T6SS research.Vibrio fluvialis(V.fluvialis)as a newly emerging foodborne pathogen,has unique characteristics in the quantity,composition,and physiological function of T6SS,which is related to its wide environmental adaptability and pathoge-nicity.This article mainly reviews the research progress of V.fluvialis T6SS,including its composition,structure,functional activity,and regulatory mechanism.

Objective:To investigate the efficacy and safety of Venetoclax combined with CACAG regimen in treatment of patients with refractory/relapse acute myeloid leukemia(R/R AML).Methods:The study was a singlecenter prospective clinical trial.The enrolled patients met the criteria for R/R AML.Treatment included Azacidine(75mg/m2,d1-7),Ara-C(75-100 mg/m2,q12h,d1-5),Aclacinomycin(20 mg d1,d3,d5),Chidamide(30 mg d1,d4),Venetoclax(100 mg d1,200 mg d2,400 mg d3-d14,in combination with Triazole Drug,reduced to 100 mg/d),and granulocyte colony-stimulating factor(300 μg/d until neutrophil recovery).The primary endpoint of observation was overall response rate after 1 course of treatment.Results:A total of 19 patients were enrolled from January 2022 to April 2023.After 1 course of treatmen,the overall response rate was 81.3％(13/16),the CR rate was 68.8％(11/16),and the PR was 12.5％(2/16).Among the 11 patients who got CR/CRi,8 cases achieved CRm(minimal residual disease negative CR)and 3 cases did not.As of March 27,2023,the median follow-up time was 111(19-406)days.The six-month overall survival and progression-free survival rates were both 55.7％,the 1-year overall survival and progression-free survival rates were 46.4％and 47.7％,respectively.In addition,compared with the non-CRm group,CRm patients had a better PFS(377 days vsi11 days,P=0.046).Treatment-related adverse events were mainly 3-4 degrees of bone marrow suppression,complicated by various degrees of infection(n=12),hypokalemia(n=12)and hypocalcemia(n=10)and elevated liver enzymes(n=8),of which 3/4 degrees accounted for 47.4％(9/19).Conclusion:The Venetoclax combined with CACAG regimen is an effective salvage therapy for patients with R/R AML,with high remission rate and safety profile.
