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.

Objective To explore the clinical characteristics and risk factors of death during hospitalization in patients with community-acquired pneumonia(CAP)complicated with diabetes mellitus(DM).Methods A retrospective analysis was performed on 566 patients with CAP hospitalized in the Second Affiliated Hospital of Kunming Medical University from January 2018 to January 2022.The patients were divided into simple CAP group(n=478)and CAP combined with diabetes(CAP+DM)group(n=88)according to whether they had diabetes,and then CAP+DM group(n=88)was divided into survival group(n=69)and death group(n =19)according to whether the patients died during hospitalization.The clinical data and laboratory test indicators of patients in different groups were compared.Cox regression analysis was used to screen the risk factors of death during hospitalization in the CAP+DM group.Receiver operating characteristic(ROC)curve was plotted to evaluate the predictive value of independent risk factors on hospitalization death.Results Compared with the simple CAP group,the CAP+DM group had significant differences in age,concomitant hypertension,coronary heart disease,CURB-65 score,neutrophil to lymphocyte ratio(NLR),C-reactive protein(CRP),procalcitonin(PCT),albumin(ALB),prealbumin(PA),glucose(GLU),serum potassium(K),calcium(Ca),phosphorus(P),magnesium(Mg),lactic acid(Lac),non-invasive ventilation time,ICU occupancy rate and mortality rate(P<0.05);Compared with the survival group,there were statistically significant differences in CURB-65 score,NLR,CRP,PCT,GIU,ALB,PA,serum iron(Fe),Ca,non-invasive ventilation time,and ICU admission rate among the death group patients(P<0.05).Cox regression analysis showed that the increase of NLR level and the decrease in PA level were the risk factors for in-hospital death in patients with CAP complicated with diabetes(P<0.05).When the PA cutoff value was 91 mg/L,the AUC,sensitivity,and specificity for predicting in-hospital death of CAP patients with diabetes were 0.849,84.2%and 81.2%,respectively.Conclusion Patients with CAP combined with diabetes are more serious and have worse prognosis than those with CAP alone.PA has a good predictive value for the prognosis of these patients.Early detection and active intervention should be carried out to reduce the in-hospital mortality of patients.

Objective To analyze the characteristics of time in range(TIR)and its relationship with oxidative stress(OS)and insulin resistance status(HOMA-IR)in patients with type 2 diabetes mellitus(T2DM)and sleep apnea-hypopnea syndrome(OSAHS).Methods According to apnea-hypopnea index(AHI),165 T2DM in patients were divided into simple T2DM group(AHI<5 times/h,n=43),T2DM combine OSAHS mild group(OSAHS-G,5≤AHI<15 times/h,n=51),T2DM combined OSAHS moderate group(OSAHS-M,15≤AHI≤30 times/h,n=40)and T2DM combine OSAHS severe group(OSAHS-S,AHI>30 times/h,n=31).TIR was calculated by dynamic blood glucose monitoring.Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and other indexes were detected and analyzed.Results Compared with simple T2DM group,the levels of HOMA-IR,8-iso-PGF2a and Ox-LDL were higher in T2DM combined OSAHS-G,OSAHS-M or OSAHS-S group,while the levels of TIR,SOD and GSH-Px were lower(P<0.05).Pearson correlation analysis showed that TIR was positively correlated with the levels of SOD and GSH-Px(P<0.05 or P<0.01),and negatively correlated with the levels of 8-iso-PGF2a,Ox-LDL,HbA1c,HOMA-IR and the severity of OSAHS(P<0.01).Logistic regression analysis showed that TIR,SOD and GSH-Px were protective factors for severe OSAHS in T2DM patients,while 8-iso-PGE2a and Ox-LDL were the risk factors for severe OSAHS.Conclusions The glucose level fluctuates greatly in patients with T2DM and OSAHS.Insulin resistance and oxidative stress are factors that affect the normalization of TIR.

Background Healthcare workers suffer from great internal and external pressure and are prone to burnout. Existing studies have shown that depressive symptoms are important influencing factors of burnout, both of which are closely related to job stress. Objective To analyze overall prevalence of burnout among healthcare workers using a new survey tool developed by our team, and to reveal potential influencing factors related to burnout. Methods A cross-sectional multi-center study was conducted in August–October 2019 and June–September 2020, using multi-stage stratified cluster sampling. A total of 8738 healthcare workers from 22 hospitals in 5 provinces (Shandong, Hubei, Hunan, Guangdong, and Chongqing) of China were selected in this study. A set of survey questionnaires, including the general information questionnaire and the Chinese versions of General Burnout Scale, Core Occupational Stress Scale, Patient Health Questionnaire-9, and Self-administered Sleep Questionnaire were distributed. Independent samples t-test or one-way ANOVA were employed for inter-group comparison of burnout. Spearman correlation was used to evaluate correlations among burnout, depressive symptoms, and occupational stress. Stepwise linear regression was conducted to identify factors independently associated with burnout. Process plug-in was used to test potential mediating effect of depressive symptoms on occupational stress and burnout. Results Of the 8738 questionnaires distributed, 8456 valid questionnaires were collected, and the recovery rate was 96.77%. Among the 8456 healthcare workers, the prevalence of burnout was 58.0%, that of occupational stress was 31.8%, and that of depressive symptoms was 31.0%. Among those with depressive symptoms and occupational stress, the proportions of burnout were 86.7% and 83.7%, respectively. According to the stepwise linear regression analysis, depressive symptoms, occupational stress, work experience, drinking, and marital status were all independent influencing factors of burnout. Especially, depressive symptoms, social support, and organization and reward had significant influences on burnout (b'=0.455, −0.183, 0.220, P<0.001). Depressive symptoms showed mediating effects on occupational stress (and its subscales) and burnout, and the contribution rates of the mediating effects were 41.00%, 47.02%, 43.44%, 56.62%, and 59.45%, respectively. Conclusion Burnout is a prominent problem among healthcare workers in the 5 provinces, with the prevalence of 58.0%. And nearly 1/3 suffering from depressive symptoms and occupational stress, which has a great impact on burnout.

Objective To investigate the value of transient elastography (TE) in the staging of hepatic fibrosis in patients with autoimmune liver disease (ALD). Methods PubMed, Embase, the Cochrane Library, CNKI, Wanfang Data, and VIP databases were searched for English and Chinese articles on TE in the staging of hepatic fibrosis in ALD published from January 2000 to January 2021. Two reviewers independently performed data extraction for the articles included, and QUADAS2 was used for quality assessment. The bivariate mixed effects model in Stata 15.0 software was used to perform the Meta-analysis. Results A total of 11 articles were included, with 1041 patients in total. In the diagnosis of significant hepatic fibrosis (F≥2), TE had a pooled sensitivity of 0.81 (95% CI : 0.75-0.86), a specificity of 0.87(95% CI 0.79-0.92), and an area under the receiver operating characteristic curve (AUC) of 0.91(95% CI 0.88-0.93); in the diagnosis of advanced hepatic fibrosis (F≥3), TE had a pooled sensitivity of 0.81(95% CI 0.74-0.87), a sensitivity of 0.90(95% CI 0.85-0.93), and an AUC of 0.92(95% CI 0.90-0.94); in the diagnosis of early-stage liver cirrhosis (F4), TE had a pooled sensitivity of 0.87(95% CI 0.74-0.93), a specificity of 0.93(95% CI 0.87-0.97), and an AUC of 0.96(95% CI 0.94-0.97). Conclusion TE has a good diagnostic value in evaluating significant liver fibrosis, advanced liver fibrosis, and early-stage liver cirrhosis in patients with ALD, especially with a relatively high diagnostic accuracy for early-stage liver cirrhosis.

Objective:To evaluate the effects of supra-arch branches bypass on cerebral oxygen saturation and hemodynamics in patients with Stanford type B aortic dissection.Methods:From January to December 2018, consecutive 27 patients with Stanford type B aortic dissection were enrolled in the study. All patients received hybrid treatment, including supra-arch branches bypass(right axillary artery-left common carotid artery-left subclavian artery) and thoracic endovascular aortic repaire(TEVAR). All the operations were performed by the same surgical team. The left and right cerebral oxygen saturation were measured after anesthesia(T1), left carotid artery occlusion(T2) and after operation(T3); peak systolic velocity(PSV) and resistance index(RI) of left and right carotid arteries were measured before(t1) and after operation(t2).Results:The left cerebral oxygen saturation was 0.62 ±0.01, 0.54±0.01 and 0.62±0.01 at T1, T2 and T3, respectively. There was significant difference between T2 and T1 and T3( P=0.002, P=0.001), but there was no significant difference between T1 and T3. The PSV of left carotid artery at t1 and t2 were(0.91±0.11)m/s and(0.76±0.09)m/s respectively, with no significant difference( P= 0.191). The RI of left carotid artery at t1 and t2 were 0.83±0.06 and 0.93±0.13 respectively, with no significant difference( P= 0.575). Conclusion:If one side of carotid artery was blocked for a short time during supra-arch branches bypass, the cerebral oxygen saturation would be decreased temporarily, but the changes of cerebral oxygen metabolism could be completely restored after operation. However, the hemodynamics of carotid artery would not change significantly. In the hybrid treatment strategy for the patients with aortic dissection Stanford type B, blocking bilateral carotid arteries can be avoided. Making the right axillary artery-left common carotid artery-left subclavian artery shunt is a safe and effective choice.

Objective To explore the gene mutation characteristics and detailed clinical presentations of hyperglycemia caused by GCK mutations in 10 patients.Methods The clinical and follow-up data of 10 patients with hyperglycemia caused by mutation of GCK gene were reviewed.The patients were ascertained between January 1,2014 and August 31,2018 at the Department of Pediatrics,the First Affiliated Hospital of Zhejiang University and Ningbo Women & Children's Hospital.Clinical data were collected,including age,gender,main complaint,family history,fasting blood glucose,fasting blood insulin,2-hour blood glucose,2-hour blood insulin after oral glucose tolerance test,glycosylated hemoglobin,anti-glutamic acid decarboxylase antibody and body mass index.Mutations of GCK gene were detected by Sanger sequencing or high-throughput sequencing of diabetes-related genes in the patients and their family members.Results There were ten patients,8 of them were male,2 were female.The ages at diagnosis varied between 4.7 to 12.3 years.The patients usually did not have obvious clinical symptoms of diabetes mellitus.Most of them were unexpectedly found to have hyperglycemia and with impaired glucose metabolism in three consecutive generations.The fasting blood glucose of patients was 6.8-7.7 mmol/L,2-hour postprandial blood glucose was 7.8-11.6 mmol/L.Fasting blood insulin was 0.5-8.5 mU/L,glucose tolerance test results showed that 2 h postprondial blood insulin was 1.3-55.4 mU/L.The level of glycosylated hemoglobin was 6.1％-6.8％.Anti-glutamic acid decarboxylase antibody was negative in all patients.The GCK mutations identified in patients and one of their parents were located at exon5 (4 cases),exon9 (2 cases),exon2 (1 case),exon4 (1 case),exon6 (1 case) and exon7 (1 case).Conclusions Most of the hyperglycemia patients caused by GCK mutations did not have typical clinical symptoms of diabetes.The fasting blood glucose was slightly elevated.Abnormal glucose tolerance test results were found in all 10 patients.Three consecutive generations of family had impaired glucose metabolism.GCK mutations located at exon 5 were common in 10 cases.There was no correlation between type of mutations and plasma glucose levels in domestic and international researches.When fasting glucose was found abnormal in clinic,a complete family history should be taken and the GCK gene should be sequenced to confirm the diagnosis in time.

OBJECTIVETo report on two cases affected with immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome (IPEX).

METHODSTwo unrelated Chinese infants affected with IPEX were investigated. Case 1 was a 4-month-old boy with neonatal diabetes and severe enteropathy. Case 2 was a 6-day newborn boy with neonatal diabetes and ketoacidosis. DNA samples of the two infants and their parents were sequenced for FOXP3 gene mutations. Suspected mutations were verified among 100 unrelated healthy controls. The function of mutations was predicted with bioinformatics software.

RESULTSBoth infants had onset of the disease during neonatal period, and manifested insulin-dependent diabetes mellitus, persistent diarrhea, eczema and malnutrition. In case 1, a novel splice site mutation was identified in intron 9 (c.967+3A>T) of the FOXP3 gene, for which his mother was a carrier. For case 2, a missense mutation (c.1150G>A) was detected in exon 11 of the FOXP3 gene, for which his mother was also a carrier. The IVS9 c.967+3A mutation was not detected among the 100 healthy controls. As predicted with Human Splicing Finder software, the c.967+3A>T mutation may influence the splicing of mRNA and affect the function of protein.

CONCLUSIONBoth cases had typical clinical manifestation of the IPEX syndrome, among whom a novel splice site mutation (IVS9 c.967+3A>T) and a missense mutation (c.1150G>A) of the FOXP3 gene were identified. The clinical manifestation of the IPEX syndrome may be variable and the mortality is high. FOXP3 gene sequencing is recommended when insulin-dependent diabetes mellitus is diagnosed during the neonatal period.

Objective: To evaluate the safety and feasibility of treating de novo coronary lesions with paclitaxel-eluting balloon. Methods: This is a retrospective study, which enrolled 76 patients with 80 de novo coronary lesions treated with paclitaxel-eluting balloons(<30% residual stenosis and there was no blood flow limited dissection after pretreatment) from April 2015 to November 2016 in Guangdong general hospital. The data of basic characteristics,procedures,devices and follow-up information were retrieved and analyzed. The primary endpoint was the composite of cardiac death, recurrent myocardial infarction and target lesion revascularization. Results: (1)The age was (63.3±10.3) years. There were 68.4%(52/76) acute coronary syndrome patients, prevalence of type 2 diabetes was 36.8%(28/76), and 64.5%(49/76)patients with at least one high bleeding risk. (2)The lesion length was (17.4±7.6)mm, and the stenosis was (88.1±8.2)%.The reference vessel diameter≥2.75 mm accounted for 51.2% (41/80), and bifurcation stenosis accounted for 67.5%(54/80). (3)53.7%(43/80) lesions were pretreated with scoring balloon to optimize plaque modification. The paclitaxel-eluting balloon length and diameter were (22.3±5.5)mm and (2.74±0.52)mm.The residual stenosis was (12.3±10.3)%. Procedural success was 88.8%(71/80).Bail-out stenting rate was 5.0%(4/80). (4)The median follow-up duration was 12(6, 25) months. Primary endpoint occurred in 3 cases (3.9%), including 2 cardiac deaths(1 patient died of recurrent myocardial infarction, and 1 patient died of acute heart failure induced by severe mitral insufficiency), and one patient receivedtarget lesion revascularization. Conclusion In case of no more than 30% residual stenosis and no blood flow limited dissection after lesion pretreatment,it is safe and feasible to treat de novo coronary lesionsusing paclitaxel-eluting balloon.
