Background  Osteoclast-associated receptor (OSCAR) is a member of the newly identified leukocyte receptor complex, and has recently been described as a key molecule in osteoclastogenesis. In this study, we measured the levels of soluble osteoclast-associated receptor (sOSCAR) in the serum of rheumatoid arthritis (RA) patients and healthy controls to examine whether sOSCAR may play a role in the process of inflammatory arthritis.
Methods  Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of sOSCAR in the serum of 40 healthy controls and 40 RA patients.
Results  The serum levels of sOSCAR were significantly lower in RA patients than in healthy controls, and were inversely associated with inflammatory activity.
Conclusion  sOSCAR is decreased in patients with RA and reduced levels of the protein are associated with increased inflammatory response.

Background  A previous study has shown that rs548234 polymorphism at PRDM1-ATG5 region is associated with rheumatoid arthritis (RA) in Caucasian populations. The aim of this study was to investigate the effect of rs548234 polymorphism at PRDM1-ATG5 region on susceptibility to RA in Chinese Han population.
Methods  We genotyped 848 RA patients and 1431 matched healthy controls for rs548234 single-nucleotide polymorphism (SNP) with a predesigned TaqMan SNP genotyping assay. Association analyses were performed on the whole data set and on rheumatoid factors (RF) and anti-cyclic citrullinated peptides (anti-CCP) antibody. Finally, we carried out combined analysis of rs548234 association with RA based on the published data.
Results  No significant difference in the genotype distribution between RA patients and healthy controls for rs548234 (C/T) polymorphism was found in Chinese Han population, neither in whole data set nor in stratified subsets, e.g. RF and anti-CCP status. Association analysis in different ethnic groups showed that rs548234 at PRDM1-ATG5 region was associated with RA in Caucasian ancestry but not in East Asian population.
Conclusions  Our results showed no involvement of rs548234 at PRDM1-ATG5 region in the susceptibility or clinical relevance of RA in Chinese Han population.

Background  Atypical meningioma is one of the rare subtypes of meningioma, which is lacking of optimal consensus on treatment strategies. This study aimed to investigate the radical treatment strategies to improve the long-term outcome of recurrent atypical meningiomas.
Methods  The prognostic factors including the age and gender of patients; the location, histology, recurrence pattern and mitotic cell rate of the tumors; and the resection extents, surgical strategies and adjuvant therapies of 15 cases of recurrent atypical meningiomas were analyzed retrospectively.
Results  The age and gender of patients were not associated with tumor recurrence. However, high recurrence rates and poor prognosis for atypical meningiomas were associated with the high mitotic cell rate, failure to achieve Simpson grade I-II resection, and without the dura and bone flap replacement intraoperatively. Post-operative radiotherapy improved the outcomes of tumors in patients after the second surgery.
Conclusion  Radical treatment strategies such as dura and bone flap replacements and radiotherapy should be considered in patients diagnosed with atypical meningiomas.

Background  Nucleophosmin plays a critical role in embryonic development. This study aimed to examine the expression pattern of nucleophosmin in glandular epithelium of human endometrium during the menstrual cycle.
Methods  Endometrial tissues used for this study were obtained from 46 non-pregnant patients who underwent hysterectomy which had been performed to treat benign diseases. Nucleophosmin expression was assessed by in situ hybridization and immunohistochemistry.
Results  At the early-, mid- and late-proliferative phase, nucleophosmin mRNA was highly expressed in glandular epithelium of human endometrium. At the secretory phase, the expression of nucleophosmin mRNA was reduced in glandular epithelium in early-secretory phase, and the expression in mid- and late-secretory phases was not detected. Similarly, nucleophosmin protein was strongly expressed in endometrial glands throughout the proliferative phase, but was gradually reduced during secretory phase.
Conclusion  Nucleophosmin mRNA and protein are expressed in glandular epithelium of human endometrium throughout the menstrual cycle.

Background  Computed tomography (CT)-guided transthoracic lung biopsy is a well-established technique for the diagnosis of pulmonary lesions. The objective of this study was to evaluate the diagnostic efficiency and complication rate of CT-guided lung biopsy in a Chinese population.
Methods  CT-guided cutting needle lung biopsies were performed in our institution on 1014 patients between January 2000 and October 2010. A chest radiograph was taken after the biopsy. Data about basic patient information, final diagnosis, and complications secondary to biopsy procedure (pneumothorax and bleeding) were extracted.
Results  The diagnostic efficiency of CT-guided lung biopsy was 94.8%; only 53 patients did not get a final diagnosis from lung biopsy. Final diagnoses found 639 malignant lesions (63.0%) and 322 benign lesions (31.8%). Pneumothorax occurred in 131 patients and 15 required insertion of an intercostal drain. Small hemoptysis occurred in 41 patients and mild parenchymal hemorrhage occurred in 16 patients. The overall complication rate was 18.5%.
Conclusions  CT-guided cutting needle biopsy of pulmonary lesions is a relatively safe technique with a high diagnostic accuracy. It can be safely performed in clinical trials.

Background  Mixed cryoglobulinemia (MC) is one of the most common and severe symptoms in chronic hepatitis C patients. The aim of this study was to investigate whether mixed cryoglobulinemia is a factor associated with sustained virological response in chronic hepatitis C patients treated with combination therapy of pegylated interferon alpha-2a and ribavirin.
Methods  This is a single-center study including 57 chronic hepatitis C patients who received combination treatments of pegylated interferon alfa-2a and ribavirin. Serum cryoglobulin was detected by cryoprecipitation prior to treatment. Serum hepatitis C virus (HCV) RNA levels were checked before treatment, during the fourth and 12th week of treatment, and during the 24th week after cessation of treatment. The genotype of HCV was determined at baseline. Logistic regression analysis was used to assess the factors associated with sustained virological response.
Results  Twenty-five patients were with MC (43.9%). Twenty-four weeks after cessation of antiviral treatment, sustained virological response achievement in MC+ patients was significantly lower than that in MC- patients (32.0% vs. 75.0%, P=0.001). Univariate Logistic regression analysis and multivariate Logistic regression analysis found that only MC (odds ratio: 6.375; 95% CI: 1.998–20.343, P=0.002) was negatively associated with sustained virological response achievement.
Conclusion  MC is an independent factor negatively associated with sustained virological response in chronic hepatitis C patients treated with pegylated interferon alpha-2a and ribavirin.

Background  Bleb-associated endophthalmitis (BAE) is a rare but severe complication of trabeculectomy with poor outcome. Various surgical methods were explored to treat such patients. However, there is no defined protocol. The aim of this study was to describe a new combined operation, and to demonstrate the outcome of the treatment.
Methods  Nine patients with BAE were enrolled in our study. The combined operation including pars plana vitrectomy (PPV), sclera patch graft (SPG) and endoscopic cyclophotocoagulation (ECP) was used to treat these patients.
Results  In the follow-up of 18–24 months, all patients with the endophthalmitis were cured, the useful visual acuity was preserved in 7 patients, and the intraocular pressure (IOP) of 8 patients was controlled just after first operation, only one needed another trans-scleral cyclophotocoagulation.
Conclusion  This combined operation is a useful method for treating the patients with BAE, with SPG and vitrectomy to control the endophthalmitis and ECP to balance the postoperative IOP.

Background  Hypertensive target organ damage (TOD) is the main reason for mortality or disability in elderly hypertensive patients. The studies on TOD of hypertension in Asia, especially in Chinese elderly hypertensive patients, are very limited. The aim of this study was to evaluate the prevalence and correlative factors of TOD in older Chinese hypertensive inpatients.
Methods  This is a retrospective survey and data were collected from the computerized medical files of hypertensive inpatients from January of 1993 to December of 2008. The analysis was done on 17 682 inpatients, aged 60 years or older, with a diagnosis of essential hypertension (EH). The evidence of hypertensive TOD and associated factors with TOD were collected.
Results  The prevalence of any hypertensive target organ involvement among these subjects was high. In multivariable Logistic regressions adjusted for potentially confounding factors, older age, male gender, diabetes, EH grade 3, systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDL-C), were independently associated with coronary artery disease. Age, duration of EH, EH grade 3, SBP, pulse pressure (PP), and homocysteine (Hcy) were independently associated with cerebrovascular disease. Age, diabetes, duration of EH, EH grade 3, SBP, PP and estimated glomerular filtration rate (eGFR) were independently associated with chronic kidney disease. Male gender, EH grade 3 and SBP were independently associated with aortic dissection.
Conclusions  The prevalence of hypertensive TOD is high in older Chinese hypertensive inpatients. Various cardiovascular risk factors are associated with hypertensive TOD. The level of SBP and severe hypertension (grade 3 hypertension) are common independent risk factors of TOD.

Background  Unplanned extubation is associated with adverse outcomes in intensive care unit. The massive burn patient differs from other critically ill patients in many ways. However, little is known about the unplanned decannulation (UD) in Burn Intensive Care Unit. This paper describes the special features of the circumstances and outcome of UD of tracheotomy tube in massive burn patients.
Methods  A case series study was performed between January 1999 and December 2008 and UD of tracheotomy tube was analyzed retrospectively. A total of 21 patients with 29 UD events were identified. Demographic data, diagnosis, intervention, UD events and outcome of UD patients were collected. Differences in proportions were compared using the chi-square (χ2) or Fisher’s exact test.
Results  Patients with UD were often burned with head and neck (67%) and combined with inhalation injury (62%). The majority of them (76%) were transferred patients, occurred early (55%) and were accidental UD (79%). UD events tended to happen in day shift (90%) and to be associated with the medical procedure that was performing by caregivers at besides (79%). Loose of the stabilizing rope, medical procedure and tracheotomy malposition were the main causes of UD. Early UD and reintubation failure were associated with patients’ death.
Conclusions  UD happened to massive burn patients can lead to patient death. Careful management of respiratory tract was essential for massive burn patients.

Background  Previous studies have shown that the functional brain activity in the resting state is impaired in Alzheimer’s disease (AD) patients. However, most studies focused on the relationship between different brain areas, rather than the amplitude or strength of the regional brain activity. The purpose of this study was to explore the functional brain changes in AD patients by measuring the amplitude of the blood oxygenation level dependent (BOLD) functional MRI (fMRI) signals.
Methods  Twenty mild AD patients and twenty healthy elderly subjects participated in the fMRI scan. The amplitude of low frequency fluctuation (ALFF) was calculated using REST software.
Results  Compared with the healthy elderly subjects, the mild AD patients showed decreased ALFF in the right posterior cingulate cortex, right ventral medial prefrontal cortex, and in the bilateral dorsal medial prefrontal cortex. No brain region with increased ALFF was found in the AD group compared with the control group.
Conclusions  The reduced activity in the posterior cingulate cortex and medial prefrontal cortex observed in the present study suggest that the functional abnormalities of those areas are at an early stage of AD. The ALFF analysis may provide a useful tool in fMRI study of AD.

Background  Among patients with advanced multivessel coronary disease, left ventricular (LV) function is widely variable, and clinical and angiographic correlates of ventricular dysfunction remain to be defined.   
Methods  Among 73 339 patients undergoing diagnostic cardiac catheterization at a single center in China, patients with left ventriculographic assessment were identified with three-vessel coronary disease with or without left main involvement. Clinical and angiographic characteristics were examined among patients with normal or varying extent of LV dysfunction, and predictors of LV impairment (ejection fraction (EF): <25%, 25%40% or >40%) were determined.
Results  Among 11 950 patients identified with three-vessel coronary disease, the sample distribution of LVEF was >40%, n=10 776; 25%–40%, n=948; <25%, n=226. Patients with reduced LV function (<40%) more commonly were male and had a history of myocardial infarction (MI), diabetes or unstable angina. Hypertension was more frequent in those with LVEF ≥40%. In a multivariate Logistic regression analysis, prior MI (odds ratio (OR), 3.37; 95% confidence interval (CI), 2.96–3.84) was most predictive of LVEF <40%, followed by male gender, diabetes, and presentation with unstable angina. For LVEF <25%, only prior MI was identified as a significant correlate of severe LV dysfunction (OR  4.06, 95% CI 3.06–5.39). Following exclusion of patients with previous MI (n=7416), male gender and diabetes were predictive of LVEF <40%, yet presentation with unstable angina was the only factor significantly associated with LVEF <25%.
Conclusion  Among individuals identified with three-vessel coronary disease with or without left main involvement, previous MI was the most significant risk factor of LV dysfunction.

Background Currently available evidence suggests that outcomes are less favorable when left main (LM) bifurcation lesions are treated with 2-stent techniques compared with a single-stent technique.We aimed to evaluate the long-term outcomes of the 2-stent techniques for treating unprotected LM bifurcation lesions in Chinese patients.Methods We enrolled 301 consecutive patients treated with drug-eluting stents (DES) implantation using 2-stent techniques for unprotected LM bifurcation lesions (MEDINA 1,1,1,70.5%).The 2-stent techniques included crush technique,V stenting,T stenting,and Culottes stenting.After stenting,both vessels were redilated at a high pressure before final kissing balloon (FKB).Clinical and angiographic data were analyzed.The primary endpoints were major adverse cardiac events (MACE),whichincluded death,myocardial infarction,and target lesion revascularization.Results Immediate procedural success was obtained in all cases with a FKB success rate of 95.3%.Follow-up data were available for all patients.The overall incidence of angiographic in-stent restenosis (ISR) rate was 20.3% and most ISRs were of the focal type.During long-term follow-up (mean duration,(54±22) months),the cumulative incidence of MACE was 11.0%,with 8 (2.7%) deaths,7 (2.3%) myocardial infarctions,and 18 (6.0%) repeated lesion revascularization.MACEs in high SYNTAX score terciles were significantly higher compared with those in low and intermediate SYNTAX score terciles (p=0.001).Conclusions Although percutaneous coronary intervention (PCI) with 2-stent technique for unprotected LM bifurcation lesions was accompanied with a slightly high incidence of ISR,the long-term clinical follow-up is acceptable.Technical modifications and stent innovations may further improve both the angiographic and clinical outcomes for patients with LM bifurcation disease treated by PCI.  相似文献

BackgroundPolymer coating on coronary stents induces vascular inflammatory response,reduces re-endothelialization,and affects long-term outcome after percutaneous coronary intervention (PCI).The SERY-1 registry aimed to determine whether a novel polymer-free paclitaxel-eluting microporous Yinyi stent could improve 1-year outcome after index procedure in real-world clinical practice.Methods Clinical and angiographic data and follow-up outcome were collected in 1045 patients who underwent PCI with implantation of ≥1 Yinyi stents between June 2008 and August 2009 at 27 medical centers.The primary endpoint was the cumulative rate of composite major adverse cardiac events (MACE) and the secondary endpoint was the incidence of stent thrombosis at 1 year.Results Overall,1376 lesions were treated successfully with 1713 Yinyi stents,and 1019 (98.7%) patients received dual antiplatelet therapy for at least 12 months.During 1-year follow-up,8 patients (0.78%) had cardiac death,6 (0.58%)suffered non-fatal myocardial infarction,and 46 (4.46%) underwent repeat PCI due to recurrence of angina,resulting in 1-year MACE-free survival of 94.09%.Stent thrombosis occurred in 10 (0.97%) patients,and the rate of Academic Research Consortium (ARC) definite or probable stent thrombosis was 0.78%.Conclusions Polymer-free paclitaxel-eluting microporous Yinyi stent is effective and safe for interventional treatment of coronary artery disease in real-world clinical practice,without recourse to carrier polymer.Potential long-term clinical advantages of this stent deserve further investigation.  相似文献

Influence of insulin resistance on long-term outcomes in patients   总被引:2,自引:0,他引:2  
Background Insulin resistance(IR)is significantly associated with coronary artery disease and cardiovascular events in patients with or without type 2 diabetes mellitus.This study aimed to evaluate the influence of IR on long-term outcomes of patients undergoing percutaneous coronary intervention(PCI)with sirolimus-eluting stent(SES)implantation.Methods A total of 467 consecutive patients undergoing SES-based PCI were divided into lR group(n=104)and non-IR group(n=363).The patients were followed up for one year.The rate of major adverse cardiac events(MACEs) including death, non-fatal myocardial infarction and recurrent angina pectoris was compared by the log-rank test,and the independent risk factors were identified by the Cox regression analysis.Results MACEs occurred more frequently,and cumulative survival rate was lower in the IR group than in the non-IR group during the follow-up (all P〈0.05).IR was an independent risk factor for the occurrence of cardiac death and non-fatal myocardial infarction(OR=2176,95% CI=1.35-5.47,P=0.034).Old age,diabetes,and multi-vessel disease were determinants for recurrent angina pectoris after PCI(P〈0.05).Subgroup analysis revealed that IR(OR=3.35,95% CI=1.07-13.59,P=0.013)and multi-vessel disease(OR=2.19,95%CI=1.01-5.14,P=0.044)were independent risk predictors for recurrent angina pectoris in patients with diabetes after PCI.Conclusions IR is associated with reduced MACE-free survival and remains an independent predictor for recurrent angina pectoris after PCI with SES implantation.  相似文献
