Objective To develop and validate a nomogram risk prediction model for in-stent restenosis(ISR)in patients undergoing carotid artery stenting(CAS).Methods A retrospective analysis was conducted on the clinical data from 267 CAS patients.The dataset was randomly divided into training set(187 cases,for modeling)and test set(80 cases,for validation)in a 7∶3 ratio.Based on whether ISR occurred within one year after CAS,patients were divided into ISR and non-ISR groups.Univariate and multivariate logistic regression analyses were conducted on the training set to identify independent influencing factors and to construct a model.The model was then validated using samples from the test set.The model's discrimination was assessed using the area under the curve(AUC)of the receiver operating characteristic(ROC),while the calibration was evaluated using the Hosmer-Lemeshow test and calibration plots.Results ISR occurred in 46 out of 267 CAS patients(17.23％)within one year after surgery.Multivariate logistic regression analysis of the training set identified hypertension[odds ratio(OR)=2.730,95％confidence interval(CI)1.124-6.630],hyperlipidemia(OR=3.135,95％CI 1.293-7.599),preoperative calcified plaque(OR=3.485,95％CI 1.422-8.542),and residual stenosis(OR=5.440,95％CI 1.570-18.854)as significant predictors of ISR in patients with CAS within one year after surgery.The predictive model achieved an AUC of 0.798(9 5％CI 0.715-0.881),with a sensitivity of 73.5％,specificity of 75.8％,and accuracy of 75.4％.The AUC of external validation of the test set was 0.764(95％CI 0.599-0.929).Hosmer-Lemeshow test yielded x2=14.76,P=0.12,while calibration plots indicated high concordance between the predicted and actual outcomes in both the training set and the test set.Conclusion The nomogram risk prediction model for ISR in CAS patients within one year after surgery demonstrates good discrimination and calibration,provi-ding valuable insights for clinical assessment of ISR risk,control of ISR incidence and precision treatment planning.

Objective To predict the causal relationship between immune cells and osteomyelitis(OM)by using Mendelian randomization.Methods Data sets of 731 immune cells and osteomyelitis were obtained from the UK Biobank and the genome wide association study.The inverse variance weighted method,weighted median method,and MR-Egger method were employed sequentially to verify the causal relationship between the 731 immune cells and osteomyelitis.Cochran's Q test,MR-Egger intercept test,mendelian randomization pleiotropy residual sum and outlier(MR-PRESSO),and leave-one-out analysis were evaluatede the stability and reliability of the results.Results A total of 21 immune cells were found to have a causal relationship with osteomyelitis(P＜0.05).Among them,T regulatory cells,classical dendritic cells and B cells were exhibited more stable causal relationships with osteomyelitis(P＜0.01).Specifically,T regulatory cells(OR=0.925,β=0.078)were identified as protective factors reducing the risk of osteomyelitis,while classical dendritic cells(OR=1.084,β=0.081)and B cells(OR=1.063,β=0.061)were identified as risk factors increasing the risk of osteomyelitis.Conclusion Twenty-one immune cells are genetically associated with the risk of osteomyelitis.

Although carbon monoxide (CO)-based treatments have demonstrated the high cancer efficacy by promoting mitochondrial damage and core-region penetrating ability, the efficiency was often compromised by protective autophagy (mitophagy). Herein, cannabidiol (CBD) is integrated into biomimetic carbon monoxide nanocomplexes (HMPOC@M) to address this issue by inducing excessive autophagy. The biomimetic membrane not only prevents premature drugs leakage, but also prolongs blood circulation for tumor enrichment. After entering the acidic tumor microenvironment, carbon monoxide (CO) donors are stimulated by hydrogen oxide (H₂O₂) to disintegrate into CO and Mn²⁺. The comprehensive effect of CO/Mn²⁺ and CBD can induce ROS-mediated cell apoptosis. In addition, HMPOC@M-mediated excessive autophagy can promote cancer cell death by increasing autophagic flux via class III PI3K/BECN1 complex activation and blocking autolysosome degradation via LAMP1 downregulation. Furthermore, in vivo experiments showed that HMPOC@M+ laser strongly inhibited tumor growth and attenuated liver and lung metastases by downregulating VEGF and MMP9 proteins. This strategy may highlight the pro-death role of excessive autophagy in TNBC treatment, providing a novel yet versatile avenue to enhance the efficacy of CO treatments. Importantly, this work also indicated the applicability of CBD for triple-negative breast cancer (TNBC) therapy through excessive autophagy.

OBJECTIVETo report on prenatal diagnosis and follow up of two patients with paternal uniparental disomy of chromosome 6 (pUPD6).

METHODSFetal cells were subjected to in situ culturing and G-banded chromosomal analysis. DNA samples of the fetuses and their parents were also analyzed with single nucleotide polymorphism microarray (SNP array).

RESULTSBoth fetuses had a normal male karyotype. SNP array analysis showed both have carried pUPD6.

CONCLUSIONpUPD6 can lead to transient neonatal diabetes mellitus type 1. Homozygous status of recessive mutations, disorder of gene imprinting, and its influence on placental function are the main factors to be considered during prenatal diagnosis and genetic counseling for pUPD6.

Objective To systematically review the efficacy and safety of drug-eluting stent(DES) versus coronary artery bypass grafting(CABG) in the treatment of left anterior descending coronary artery(CAD) stenosis.Methods Literature about the efficacy and safety of DES versus CABG for LAD stenosis was retrieved from digital databases of MEDLINE, EMbase, PubMed, and the Cochrane Library by November 2016.Data extraction and quality assessment of included studies were conducted by two independent reviewers.RevMan 5.3 software was used to perform meta-analysis.Results Ten studies involving 9771 patients were finally included.The results of meta-analysis showed that there was no significant difference in mortality [RR=0.88,95%CI(0.70,1.11),P=0.28],major adverse cardiovascular events[MACE,RR=1.04,95%CI(0.88,1.24),P=0.63] or myocardial infarction [MI,RR=0.92,95%CI(0.56,1.53),P=0.75], but PCI-DES significantly increased the risk of TVR [OR=2.43,95%CI(1.61,3.69),P<0.0001].Conclusion For LAD stenosis, PCI-DES strategy causes as high a rate of mortality, MACE and MI as CABG or DES, but PCI-DES can significantly increase the risk of TVR, so we should be cautious clinically.

Objective To analyze the perioperative conditions and long-term survival of patients with non-small cell lung cancer (NSCLC) after thoracoscopic lobectomy. Methods 119 patients with NSCLC underwent thoracoscopic lobectomy from January 2006 to December 2012 were enrolled in the study, then collecting and analyzing their perioperative indicators, pathological results and follow-up data. Results 9 patients converted to thoracotomy with a conversion rate of 7.0 %. The median operation time, the median intraoperative blood loss and off-bed activity time were 170 min (65~440 min), 90 ml (15~3 000 ml) and (32.9 ± 16.3) h after operation respectively. The time and amount of postoperative drainage, the length of hospital stay were (6.7 ± 3.2) d, (1 690.0 ± 410.5) ml, (9.2 ± 4.0) d respectively. The incidence of perioperative mortality and postoperative complications were 0.8 %, 13.4 % respectively. For postoperative pathological type, 96 cases of adenocarcinoma, 19 cases of squamous carcinoma, 2 cases of adenosquamous carcinoma and 2 cases of large cell carcinoma. For discharge patients, the median follow-up time was 34.5 months (0 ~ 102 months). The incidence of local recurrence and distant metastasis in observation group were 5.0 % and 17.6 % respectively. 1-year overall survival (OS) and disease free survival (DFS) were 85.3 % and 79.5 %, 3-year OS and DFS were 69.8 % and 64.8 %, 5-year OS and DFS were 60.8 %and 58.6 % respectively. There was no significant difference in 1-year, 3-year and 5-year OS and DFS between adenocarcinoma and squamous carcinoma (P > 0.05) while there were significant difference in local recurrence and distant metastasis among different stages (P < 0.05). In addition to slightly low OS, DFS of Ⅲ a , Ⅲ b and Ⅳ DFS and OS, the overall living conditions among all stage were similar. Conclusions The long-term survival condition of thoracoscopic lobectomy for NSCLC is ideal, and it’s a safe and effective operation, worthy of clinical promoting.
