BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

BACKGROUND: Urolithiasis is a widespread disease with a high prevalence worldwide. This study aims to evaluate the disease burden of urolithiasis and its trends from 1990 to 2021 globally, based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 database. METHODS: The numbers and age-standardized rates (ASRs) of incidence, disability-adjusted life years (DALYs), and mortality of urolithiasis were extracted from GBD 2021 to represent the disease burden. Joinpoint regression analyses were conducted to assess the temporal trends in the burden of urolithiasis. The male-to-female ASR ratio indices were used to evaluate sex disparities. Additionally, we explored the relationship between the ASR ratio and the sociodemographic index (SDI). RESULTS: The total numbers of incidence, DALY, and mortality of urolithiasis were 105,983,780 cases (95% uncertainty interval [UI] = 88,349,356-128,645,155 cases), 693,444 cases (95% UI = 567,765-850,490 cases), and 17,672 cases (95% UI = 13,932-21,241 cases), respectively, in 2021. There is an increasing trend in the number of these measures globally, whereas the ASRs have decreased over the past 30 years. The age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) were significantly higher in males than in females in 2021. The sex disparities in the age-standardized DALY rate (ASDR) and ASMR of urolithiasis were negatively correlated with the SDI. In 2021, the ASIR of urolithiasis was 964.70 (95% UI = 801.26-1175.09) per 100,000 people in China, which is much lower than the global average (1242.84 [95% UI = 1034.94-1506.99] per 100,000 people). Compared with the global average, a more pronounced decline in ASIR was observed in China from 1793.16 (1446.0-2235.14) in 1990 to 964.70 (801.26-1175.09) per 100,000 people in 2021. CONCLUSIONS Urolithiasis poses a significant healthcare burden worldwide. More robust global and national strategies are warranted to address the prevention and treatment, especially in low SDI countries and regions.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To investigate the effects of circDNMT1 on the proliferation,apoptosis and epithelial-mesenchymal transition(EMT)of triple-negative breast cancer(TNBC)cells by regulating miR-377-3p/PUM1 axis.Methods The TNBC tissues and adjacent normal tissues of 24 patients with TNBC treated in Danzhou People's Hospital from 2018 to 2021 were collected.qRT-PCR and Western blot were used to detect the expression of circDNMT1,miR-377-3p,and PUM1 protein in tissue and mouse normal breast epithelial cell line HC11 and TNBC cell lines 4T1,Eph41424,and JC.4T1 cells were divided into the 4T1 group(untransfected),the si-NC group(transfected with si-NC),the si-DNMT1 group(transfected with si-DNMT1),the si-DNMT1+anti-NC group(simultaneously transfected with si-DNMT1 and anti-NC),and the si-DNMT1+anti-miR-377-3p group(simultaneously transfected with si-DNMT1 and anti-miR-377-3p).qRT-PCR was used to detect the expression of circDNMT1 and miR-377-3p of 4T1 cells in each group;CCK-8 was used to detect the proliferation of 4T1 cells in each group;flow cytometry was used to detect the apoptosis of 4T1 cells in each group;Western blot was used to detect the expression of PUM1,EMT-related proteins and apoptosis-related proteins of 4T1 cells in each group;TargetScan website was used to predict the binding sites of miR-377-3p with circDNMT1 and PUM1;dual luciferase report was used to verify the targeting relationships of miR-377-3p with circDNMT1 and PUM1.After inoculation with 4T1 cells,BALB/c mice were randomly divided into the blank control group(injected with equal amount of normal saline),the negative control group(injected with si-NC via tail vein),the DNMT1 silencing group(injected with si-DNMT1 via tail vein),the combined control group(injected with si-DNMT1 and anti-NC via tail vein),and the combined silencing group(injected with si-DNMT1 and anti-miR-377-3p via tail vein),the tumor massess of mice were recorded and the morphological changes of tumors were observed by hematoxylin-eosin staining.Results circDNMT1 and PUM1 were up-regulated in TNBC tissues and cells,and miR-377-3p was down-regulated.The expression difference was most obvious in 4T1 cells,so 4T1 cells were selected for subsequent experiments.Compared with the 4T1 group and the si-NC group,the expression of miR-377-3p,the apoptosis rate of 4T1 cells,the expression levels of Bax,cleaved caspase-3 and E-cadherin protein of 4T1 cells in the si-DNMT1 group were significantly increased(P<0.05),the circ-DNMT1 level,the expression level of PUM1 protein,OD values at 24 hours and 48 hours,the expression level of Bcl-2,N-cadherin,Vimentin protein were significantly decreased(P<0.05).Compared with the si-DNMT1 group and the si-DNMT1+anti-NC group,the expression of miR-377-3p,the apoptosis rate of 4T1 cells,the expression levels of Bax,cleaved caspase-3 and E-cadherin proteins of 4T1 cells in the si-DNMT1+anti-miR-377-3p group were significantly decreased(P<0.05),the expression level of PUM1 protein,OD values at 24 hours and 48 hours,the expression levels of Bcl-2,N-cadherin,Vimentin proteins were significantly increased(P<0.05).Compared with the miR-NC+WT-circDNMT1 group,the cell luciferase activity in the miR-377-3p mimic+WT-circDNMT1 group was significantly decreased(P<0.05);compared with the miR-NC+WT-PUM1 group,the cell luciferase activity in the miR-377-3p mimic+WT-PUM1 group was significantly decreased(P<0.05).The tumor cells in the blank control group and the negative control group were densely arranged with clear boundary;the tumor cells in the DNMT1 silencing group and the combined control group were loosely arranged,the nuclei were pyknotic,and the cell fragments were increased;the tumor cells in the combined silencing group were densely arranged and the boundaries tended to be clear.Compared with the blank control group and the negative control group,the tumor mass of mice in the DNMT1 silencing group was significantly decreased(P<0.05).Compared with the DNMT1 silencing group and the combined control group,the tumor mass of mice in the combined silencing group was significantly increased(P<0.05).Conclusion Silencing circDNMT1 may inhibit the expression of PUM1 by up-regulating miR-377-3p,thereby inhibiting the proliferation and EMT of TNBC cells,and promoting cell apoptosis.

Objective:With the in-depth study of complement dysregulation,glomerulonephritis with dominant C3 has received increasing attention,with a variety of pathologic types and large differences in symptoms and prognosis between pathologic types.This study analyzes the clinical,pathological,and prognostic characteristics of different pathological types of glomerulonephritis with dominant C3,aiming to avoid misdiagnosis and missed diagnoses. Methods:The clinical,pathological,and follow-up data of 52 patients diagnosed as glomerulonephritis with dominant C3 by renal biopsy from June 2013 to October 2022 were retrospectively analyzed.According to the clinical feature and results of pathology,15 patients with post-infectious glomerulonephritis(PIGN)and 37 patients with of non-infectious glomerulonephritis(N-PIGN)were classified.N-PIGN subgroup analysis was performed,and 16 patients were assigned into a C3-alone-deposition group and 21 in a C3-dominant-deposition group,or 27 in a C3 glomerulopathy(C3G)group and 10 in a non-C3 nephropathy(N-C3G)group. Results:The PIGN group had lower creatinine values(84.60 μmol/L vs 179.62 μmol/L,P= 0.001),lower complement C3 values(0.36 g/L vs 0.74 g/L,P<0.001)at biopsy,and less severe pathological chronic lesions compared with the N-PIGN group.In the N-PIGN subgroup analysis,the C3-dominant-deposition group had higher creatinine values(235.30 μmol/L vs 106.70 μmol/L,P=0.004)and higher 24-hour urine protein values(4 025.62 mg vs 1 981.11 mg,P=0.037)than the C3-alone-deposition group.The prognosis of kidney in the PIGN group(P=0.049),the C3-alone-deposition group(P=0.017),and the C3G group(P=0.018)was better than that in the N-PIGN group,the C3-dominant-deposition group,and the N-C3G group,respectively. Conclusion:Glomerulonephritis with dominant C3 covers a variety of pathological types,and PIGN needs to be excluded before diagnosing C3G because of considerable overlap with atypical PIGN and C3G;in addition,the deposition of C1q complement under fluorescence microscope may indicate poor renal prognosis,and relevant diagnosis,treatment,and follow-up should be strengthened.

Objective To investigate the impact of different infusion media on the flow rate of infusion pumps.Methods Ten infusion pumps were randomly selected and tested for infusion rates using deionized water,saline solution,glucose solution,and parenteral nutrition solution.The infusion flow rate was set at 30 mL/h,and the testing methodology conformed to the standards for the calibration and quality control of syringe pumps and infusion pumps.Results For infusion set A,the infusion rate was unaffected by the infusion media,remaining within the acceptable quality control standards.For infusion set B,when infused with deionized water,saline solution,and glucose solution,the infusion errors were within the quality control standards.However,when using parenteral nutrition solution as the infusion medium,the infusion error exceeded the acceptable quality control standards.Conclusion Both the infusion set and the infusion medium can affect the flow rate of infusion pumps.It is crucial to calibrate the flow rate according to the specific infusion medium to reduce medical risks associated with infusion pumps during clinical use.

Background::Dual-energy computed tomography (DECT) is purported to accurately distinguish uric acid stones from non-uric acid stones. However, whether DECT can accurately discriminate ammonium urate stones from uric acid stones remains unknown. Therefore, we aimed to explore whether they can be accurately identified by DECT and to develop a radiomics model to assist in distinguishing them.Methods::This research included two steps. For the first purpose to evaluate the accuracy of DECT in the diagnosis of uric acid stones, 178 urolithiasis patients who underwent preoperative DECT between September 2016 and December 2019 were enrolled. For model construction, 93, 40, and 109 eligible urolithiasis patients treated between February 2013 and October 2022 were assigned to the training, internal validation, and external validation sets, respectively. Radiomics features were extracted from non-contrast CT images, and the least absolute shrinkage and selection operator (LASSO) algorithm was used to develop a radiomics signature. Then, a radiomics model incorporating the radiomics signature and clinical predictors was constructed. The performance of the model (discrimination, calibration, and clinical usefulness) was evaluated.Results::When patients with ammonium urate stones were included in the analysis, the accuracy of DECT in the diagnosis of uric acid stones was significantly decreased. Sixty-two percent of ammonium urate stones were mistakenly diagnosed as uric acid stones by DECT. A radiomics model incorporating the radiomics signature, urine pH value, and urine white blood cell count was constructed. The model achieved good calibration and discrimination {area under the receiver operating characteristic curve (AUC; 95% confidence interval [CI]), 0.944 (0.899–0.989)}, which was internally and externally validated with AUCs of 0.895 (95% CI, 0.796–0.995) and 0.870 (95% CI, 0.769–0.972), respectively. Decision curve analysis revealed the clinical usefulness of the model.Conclusions::DECT cannot accurately differentiate ammonium urate stones from uric acid stones. Our proposed radiomics model can serve as a complementary diagnostic tool for distinguishing them in vivo.

OBJECTIVE To investigate the effect of salidroside (Sal) on bone loss in obstructive sleep apnea syndrome(OSAS) rats by regulating the osteoprotegerin(OPG)/receptor activator of nuclear factor kappa-B ligand(RANKL) pathway. METHODS Rats were randomly divided into(12 rats/group) control group,OSAS group,Sal-L,Sal-M,and Sal-H groups(17.5,35,70 mg/kg). Except for the control group,all other groups were used to replicate the OSAS rat model through hypoxia and reoxygenation cycles. Bone density meters,three-point bending experiments,and Micro CT were applied to measure the bone density,biomechanics,and microstructural changes of the femur in rats. ELISA method was applied to detect serum levels of osteocalcin(BGP),alkaline phosphatase(ALP),and cross-linked carboxy-terminal telopeptide of type Ⅰ collagen(CTX-I). RT-PCR was applied to detect OPG and RANKL mRNA levels in the femur. Western blotting was applied to detect the expression of OPG/RANKL pathway proteins in the femur. RESULTS Compared with the control group,the bone density,maximum intensity,maximum load,trabecular bone volume fraction(Tb.BV/TV),trabecular number(Tb.N),trabecular thickness(Tb.Th),BGP,ALP,OPG mRNA and protein expression,OPG/RANKL ratio of rats in the OSAS group were decreased,the mRNA and protein expression of CTX-I and RANKL were increased(P<0.05). Compared with the OSAS group,the bone density,maximum intensity,maximum load,Tb.BV/TV,Tb.N,Tb.Th,BGP,ALP,OPG mRNA and protein expression,OPG/RANKL ratio of rats in the Sal-L,Sal-M,and Sal-H groups were increased sequentially,the mRNA and protein expression of CTX-I and RANKL were decreased sequentially,the above changes were most great in the Sal-H group(P<0.05). CONCLUSION Salidroside promotes bone formation and inhibits bone resorption by increasing OPG expression and decreasing RANKL expression,thereby reducing bone loss in OSAS rats.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.
