Objective To compare the safety and efficacy of direct and remedial rotational atherectomy in the treatment of heavily calcified coronary artery lesions.Methods We retrospectively reviewed 58 patients admitted in the Shanghai Chest Hospital and Liaocheng People Hospital from May 2012 to July 2015 who had received stent implantation and rotational atherectomy.The 58 patients were divided into two groups which were the direct atherectomy group (n =27) and the remedial atherectomy group (n =31).General clinical date,lesion and procedural characteristics,intraoperative complications,in-hospital and follow-up MACCE were compared between the two groups.Results There were no differences between the two groups in general clinical date intraoperative complications,amount of contrast agent used,proceduraltime,rates of in-hospital and follow-up MACCE.Nevertheless,compared with the direct artherectomy group,the remedial group had more number of balloon dilations during procedure [3 (1,5) vs.2 (1,2),P ＜ 0.001] and higher peak cardiac troponin levels [1.1 (0.3,3.0) μg/L vs.0.5 (0.1,2.3) μg/L,P =0.032].Conclusions Remedial rotational atherectomy with drug-eluting stent had the same safety and efficacy as direct atheretomy with drug-eluting stent in treating patients with heavily calcified coronary lesions.It is reasonable and safe to transform routine PCI to remedial rotational atherectomy when the 2.0 mm semi compliant balloon or/and 2.5 mm non-compliant balloon cannot pass through or dilate the lesions.

This article reviews the status quo of hypoglycemia in patients with type 2 diabetic kidney disease and sorts out its influencing factors from four aspects: general factors, treatment factors, metabolic factors and other factors, so as to provide a reference for medical and nursing staff to carry out related research on hypoglycemia prevention and intervention in patients with type 2 diabetic kidney disease in the future.

OBJECTIVETo explore the predictive value of high-sensitivity C reactive protein (hsCRP) in middle-aged population during the peripheral arteriosclerosis.

METHODSRandom sampling method was used in the study. In 2006-2007 Kailuan Group health examination of 101,510 employees, using stratified random sampling method to select 5,852 as observational cohort included, in the final with a standard queue 5,440 in December 2009. This study selected to participate in the 2012-2013 health examination cohort as the research object, in accordance with the inclusion criteria ultimately selected survey 3,978, select the epidemiological investigation, physical examination, laboratory testing data analysis. Of the 3 978 subjects, 2,282 were male and 1,696 were female, and the baseline age was (53.80±11.14) years. According to the baseline hsCRP quartile level was divided into four groups for comparison of baseline data, using multiple linear regression analysis between hsCRP and brachial-ankle pulse wave velocity (baPWV). Area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate the prediction of hsCRP levels in peripheral arteriosclerosis.

RESULTSWith increase of hsCRP levels, the survey of baseline levels of baPWV showed increasing trend, (1,445.49±300.55), (1,494.46±307.94), (1,547.67±320.34), (1,621.32±342.53) cm/s, respectively. Multiple linear regression results showed that age, by logarithmic transformation of hsCRP (lghsCRP) level, systolic blood pressure and fasting blood glucose for each additional unit, baPWV levels were increased 266.47, 58.00, 5.02, 39.79 cm/s (P<0.001), and BMI for each additional unit, baPWV level decreased 9.52 cm/s (P=0.030). The prediction of hsCRP in peripheral artery showed that lghsCRP level of AUC to 0.59 (95% CI: 0.57-0.61), lower than the age and systolic blood pressure predicted value AUC (95% CI) of 0.69 (0.67-0.71), 0.75 (0.73-0.77), respectively.

CONCLUSIONThe hsCRP level could not predict the peripheral arteriosclerosis alone, and the combined age and systolic blood pressure level could have better predictive value.

Objective To systematically analyze and compare studies related to the intervention effect of topical oxygen therapy on patients with diabetic foot ulcers,and provide references for nursing practice.Methods We searched PubMed,Embase,Web of Science,CENTRAL,CINAHL,Clinical Trial,China Biomedical Literature Database,CNKI,Wanfang Database,and VIP from inception to February 1,2023,to collect studies on the effect of topical oxygen therapy interventions on patients with diabetic foot ulcers.2 researchers independently screened the litera-ture,and extracted the information,and a meta-analysis of the included literature was performed by RevMan 5.4 software.Results 8 studies with 622 patients were included.Meta-analysis results showed that compared with con ventional care,topical oxygen therapy improved the response rate[RR=1.59,95％CI(1.16,2.17),P=0.004]and the reduction of diabetic foot ulcer area[MD=28.78,95％CI(14.83,42.73),P＜0.001],and the method did not increase the incidence of adverse events[RR=0.83,95％CI(0.63,1.10),P=0.190],but the difference was not statistically significant in terms of healing time[MD=9.86,95％CI(-15.39,35.11),P=0.440].Conclusion Topical oxygen therapy helps to im-prove the response rate and reduce the ulcer size in patients with diabetic foot ulcers with a better safety profile,but the effect of the intervention on healing time is unclear.Further high-quality randomized controlled trials should be conducted in the future to validate the efficacy of topical oxygen therapy in patients with diabetic foot ulcers.
