ABSTRACT

Objective@#The antibacterial properties and bonding strength of 3M orthodontic adhesive resin modified by chlorhexidine acetate (CHA) composite mesoporous silica were investigated.@*Methods@# CHA with different mass fractions was encapsulated in mesoporous silica nanoparticles (MSNs) (denoted CHA@MSNs). Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to characterize the samples. The 3M Z350XT flow resin was divided into 4 groups: group A: 3M+CHA@MSNs (0%); group B: 3M+CHA@MSNs (3%); group C: 3M+CHA@MSNs (5%); and group D: 3M+CHA@MSNs (6.4%), with mass scores of 0%, 3%, 5%, and 6.4%, respectively. The shear strength of the modified adhesive was tested by a universal electronic material testing machine, the adhesive residue was observed by a 10 × magnifying glass, and the adhesive Remnant index (ARI) was calculated. The four groups of modified adhesives were cultured with Streptococcus mutans. The OD540 value of the bacterial solution was measured by a spectrophotometer, and the amount of plaque attachment was observed by scanning electron microscopy to evaluate the antibacterial performance of the adhesives.@*Results@#Infrared spectroscopic analysis of CHA@MSNs showed that CHA was successfully loaded onto MSNs. Under scanning electron microscopy, it could be seen that, after Cha was combined with MSNs, the structure of MSNs changed, as the boundary was fuzzy and aggregated into a layered structure. A comparison of shear strength revealed a statistically significant difference between the groups containing CHA@MSNs and the groups without CHA@MSNs (P<0.05). The value of the shear strength in group D decreased the most, while there was no statistically significant difference between group B and group C (P > 0.05). There was no statistical significance across all groups (P > 0.05), suggesting that the addition of CHA@MSNs had little effect on the bracket shedding. The OD540 value of bacterial fluid indicated that the difference among groups A, B and C was statistically significant (P < 0.05), and the antibacterial effect of group C was the best; there was no statistically significant difference between group C and group D (P > 0.05).@*Conclusions@#Therefore, adding 5% CHA@MSN antibacterial agent significantly improved the antibacterial effect and did not affect the bond strength.

ABSTRACT

Objective To investigate the correlation between smoking, white blood cell counts, and serum bilirubin levels in male radiation workers, and to explore the role of systemic inflammatory response in the changes of serum bilirubin level induced by smoking. Methods Occupational health examination data of 1 320 male radiation workers in a medical institution was collected. Linear regression analysis method was used to analyze the correlations between smoking and white blood cell counts, between smoking and serum bilirubin levels, and between white blood cell counts and serum bilirubin levels. Results There was a significant positive correlation between smoking and white blood cell counts (P 0.05). By dividing white blood cell counts into two groups, an inverse correlation was found between smoking and serum bilirubin levels in the high white blood cell count group (P < 0.05). Conclusion Serum bilirubin may be an effective indicator of early health damage caused by smoking in male radiation workers. Smoking may induce inflammatory reaction, thus deplete serum bilirubin and cause its levels to drop.

ABSTRACT

@#BACKGROUND: Approximately 20% to 30% of patients with coronary artery disease (CAD) develop recurrent angina pectoris following successful and complete coronary revascularization utilizing percutaneous coronary intervention (PCI). We aim to investigate predictors of recurrent angina pectoris in patients who have undergone successful coronary revascularization using PCI, but on repeat coronary angiography have no need for secondary revascularization. METHODS: The study comprised 3,837 patients with CAD, who were enrolled from January 2007 to June 2019. They had undergone successful PCI; some of them redeveloped angina pectoris within one year after the procedure, but on repeat coronary angiography had no need for revascularization. Thrombolysis in myocardial infarction (TIMI) frame count was used to evaluate the velocity of coronary blood in the follow-up angiogram. Multivariate logistic regression was used to investigate risk factors for recurrent angina pectoris. Similarly, predictors of recurrent angina according to the TIMI frame count were assessed using multivariate linear regression. RESULTS: In this retrospective study, 53.5% of patients experienced recurrent angina pectoris. By multivariate logistic regression, the following characteristics were statistically identified as risk factors for recurrent angina pectoris: female sex, older age, current smoking, low-density lipoprotein cholesterol (LDL-C) ≥1.8 mmol/L, and an elevated TIMI frame count (P for all <0.05). Similarly, using multivariate linear regression, the statistical risk factors for TIMI frame count included: female sex, older age, diabetes, body mass index (BMI), post-procedural treatment without the inclusion of dual antiplatelet therapy. CONCLUSIONS: Patient characteristics of female sex, older age, diabetes, and elevated BMI are associated with an increased TIMI frame count, coronary microcirculation dysfunction, and recurrent angina pectoris after initially successful PCI. In addition, current smoking and LDL-C ≥1.8 mmol/L are risk factors for recurrent angina pectoris. In contrast, the treatment with dual antiplatelet therapy is negatively correlated with a higher TIMI frame count and the risk of recurrent angina pectoris.

ABSTRACT

BACKGROUND@#Drug-coated balloons (DCBs) have emerged as potential alternatives to drug-eluting stents in specific lesion subsets for de novo coronary lesions. Quantitative flow ratio (QFR) is a method based on the three-dimensional quantitative coronary angiography and contrast flow velocity during coronary angiography (CAG), obviating the need for an invasive fractional flow reserve procedural. This study aimed to assess the serial angiographic changes of de novo lesions post-DCB therapy and further explore the cut-off values of lesion and vessel QFR, which predict vessel restenosis (diameter stenosis [DS] ≥50%) at mid-term follow-up.@*METHODS@#The data of patients who underwent DCB therapy between January 2014 and December 2019 from the multicenter hospital were retrospectively collected for QFR analysis. From their QFR performances, which were analyzed by CAG images at follow-up, we divided them into two groups: group A, showing target vessel DS ≥50%, and group B, showing target vessel DS <50%. The median follow-up time was 287 days in group A and 227 days in group B. We compared the clinical characteristics, parameters during DCB therapy, and QFR performances, which were analyzed by CAG images between the two groups, in need to explore the cut-off value of lesion/vessel QFR which can predict vessel restenosis. Student's t test was used for the comparison of normally distributed continuous data, Mann-Whitney U test for the comparison of non-normally distributed continuous data, and receiver operating characteristic (ROC) curves for the evaluation of QFR performance which can predict vessel restenosis (DS ≥50%) at mid-term follow-up using the area under the curve (AUC).@*RESULTS@#A total of 112 patients with 112 target vessels were enrolled in this study. Group A had 41 patients, while group B had 71. Vessel QFR and lesion QFR were lower in group A than in group B post-DCB therapy, and the cut-off values of lesion QFR and vessel QFR in the ROC analysis to predict target vessel DS ≥50% post-DCB therapy were 0.905 (AUC, 0.741 [95% confidence interval, CI: 0.645, 0.837]; sensitivity, 0.817; specificity, 0.561; P < 0.001) and 0.890 (AUC, 0.796 [95% CI: 0.709, 0.882]; sensitivity, 0.746; specificity, 0.780; P < 0.001).@*CONCLUSIONS@#The cut-off values of lesion QFR and vessel QFR can assist in predicting the angiographic changes post-DCB therapy. When lesion/vessel QFR values are <0.905/0.890 post-DCB therapy, a higher risk of vessel restenosis is potentially predicted at follow-up.

ABSTRACT

Extranodal natural killer/T-cell lymphoma (ENKTCL) is the subtype of non-Hodgkin lymphoma with high heterogeneity and invasiveness. Though most ENKTCL patients are present as early-stage at diagnosis, clinical prognosis significantly differs due to the limitations of clinical staging. Radiotherapy (RT) and chemotherapy (CT) are the first-line treatments for early ENKTCL patients. However, there is no consensus on the combined modalities of RT and CT, and their optimal strategy. With the continuous renewal of clinical staging and prognostic models, early-stage ENKTCL patients tend to accept risk-adapted treatment with proper stratification. In this review, the latest research progresses on clinical staging, prognostic models and treatment were retrospectively analyzed, aiming to provide references for clinical decision-making.

ABSTRACT

Objective:To evaluate the clinical efficacy of Jianpi-Huazhuo Decoction in the treatment of complication patients with phlegm-dampness in type 2 diabetes mellitus (T2DM) and Diabetic nephropathies (DN). Methods:A total of 72 patients with with phlegm dampness T2DM and DN in Huaibei Traditional Chinese Medicine Hospital of Anhui Province from June 2018 to June 2020 were randomly divided into two groups with 36 in each group. The control group were treated with oral metformin sustained-release tablets on the basis of diabetes propaganda. The observation group was treated with Jianpi-Huazhuo Decoction on the basis of the control group. Both groups were treated for 4 weeks. The blood glucose (plasma, enzyme method), HbA1c (whole blood, high performance liquid chromatography) and fasting insulin (serum, chemiluminescence method) were measured, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Plasma BUN, SCR and urinary albumin excretion rate (UAER) were measured by automatic biochemical analyzer. The plasma laminin (LN), procollagen Ⅲ (PC Ⅲ) and collagen type Ⅳ (Ⅳ-c) were detected by ELISA. The adverse events during treatment were observed and the clinical efficacy was evaluated. Results:The total effective rate was 86.1% (31/36) in the observation group and 58.3% (21/36) in the control group ( χ2 =6.923, P=0.009). After treatment, the levels of FBG, 2 hPG, HbA1c, FINS and HOMA-IR in the observation group were significanlty lower than those in the control group ( t values were 4.242, 2.751, 3.565, 3.613 and 4.512, respectively, all Ps<0.05). After treatment, the plasma levels of LN, PC Ⅲ and Ⅳ-c were significanlty lower than those in the control group ( t values were 3.612, 1.864 and 2.046, respectively, all Ps<0.05). After treatment, the levels of serum creatinine and urinary albumin excretion rate in the control group were significanlty lower than those in the control group ( t values were 5.864 and 3.286, respectively, all Ps<0.05). Conclusion:The Jianpi-Huazhuo Decoction can reduce the blood glucose level and renal fibrosis related factors in patients with phlegm dampness T2DM complicated with DN, improve the clinical symptoms and improve the clinical curative effect.

ABSTRACT

Objective:To investigate the correlation between 24 h blood pressure variability and early neurological improvement (ENI) in patients with large vessel occlusion (LVO) after endovascular thrombectomy (ET).Methods:Patients with LVO received ET in the Emergency Department, the Affiliated Hospital of Nantong University from January 2012 to February 2018 were enrolled retrospectively. During the first 24 h after ET, the blood pressure was recorded every 2 h, and blood pressure variability was evaluated by standard deviation (SD) and successive variation (SV). At 24 h after ET, the National Institutes of Health Stroke Scale (NIHSS) score was evaluated again. The re-evaluation of 0 point or a decrease of ≥4 from the baseline score was defined as ENI. Multivariate logistic regression analysis was used to evaluate the relationship between blood pressure variability and ENI. Results:A total of 74 patients with LVO received ET were enrolled, of which 39 (52.7%) had ENI. Univariate analysis showed that the proportion of patients with good recanalization in the ENI group after procedure were significantly higher than that in the non-ENI group ( P<0.05), while the average systolic blood pressure, average diastolic blood pressure, systolic blood pressure variability (SBPV) -SD and SBPV-SV within 24 h after ET and baseline total cholesterol level were significantly lower than those in the non-ENI group (all P<0.05). Multivariate logistic regression analysis showed that higher SBPV-SV was an independent risk factor for non-ENI (odds ratio 1.223, 95% confidence interval 1.038-1.440; P=0.016). Conclusion:Higher SBPV-SV after ET is associated with poor early neurological improvement in patients with LVO, and it is expected to be a potential target for blood pressure management in patients after ET.

ABSTRACT

Objective:To investigate the relationship between absolute lymphocyte count (ALC) and prognosis of extranodal nasal NK/T cell lymphoma (ENKTL).Methods:The data of 184 patients with ENKTL who were admitted to Shanxi Provincial Cancer Hospital and the Second People's Hospital of Datong in Shanxi Province from January 2002 to December 2018 were retrospectively analyzed. Contal-O'Quigley variable point method was used to calculate the optimal cut-off value of ALC for predicting the prognosis of ENKTL, and the patients were divided into two groups based on this value. Kaplan-Meier method was used to analyze the survival of the two groups of patients. Cox proportional hazard regression model was used for univariate and multivariate survival analyses.Results:According to the Contal-O'Quigley variable point method, the best cut-off value of ALC for predicting ENKTL prognosis was 1.5×10 9/L. According to this value, patients were divided into ALC>1.5×10 9/L group (98 cases) and ALC≤1.5×10 9/L group (86 cases). Compared with the ALC≤1.5×10 9/L group, the proportions of patients with Eastern Cooperative Oncology Group (ECOG) score ≥2 points, serum lactate dehydrogenase (LDH)> 245 U/L, Korean prognostic index (KPI) score 2-4 points and international prognostic index (IPI) score 2-5 points were lower in the ALC>1.5×10 9/L group, but the proportion of patients with hemoglobin > 120 g/L was higher (all P < 0.05). The overall survival (OS) and progression-free survival (PFS) in the ALC>1.5×10 9/L group were better than those in the ALC≤1.5×10 9/L group (3-year OS rate: 65.7% vs. 45.4%, 5-year OS rate: 61.0% vs. 36.6%; 3-year PFS rate: 61.7% vs. 41.0%, 5-year PFS rate: 51.9% vs. 32.2%; all P < 0.05). Multivariate Cox regression analysis showed that ECOG score, serum LDH level, ALC, radiotherapy and L-asparaginase-containing chemotherapy were independent influencing factors of OS and PFS (all P < 0.05), and for OS, when ALC>1.5×10 9/L compared with≤1.5×10 9/L, RR was 0.634 (95% CI 0.398-1.008, P=0.050), and for PFS, RR was 0.625 (95% CI 0.406-0.962, P=0.033). Conclusion:Patients with high ALC have good prognosis, and therefore ALC may be a powerful prognostic factor of ENKTL.

ABSTRACT

BACKGROUND@#Acute coronary syndromes mainly result from abrupt thrombotic occlusion caused by atherosclerotic vulnerable plaques (VPs) that suddenly rupture or erosion. Fibrous cap thickness (FCT) is a major determinant of the propensity of a VP to rupture and is recognized as a key factor. The intensive use of statins is known to have the ability to increase FCT; however, there is a risk of additional adverse effects. However, lower dose statin with ezetimibe is known to be tolerable by patients. The present study aimed to investigate the effect of intensive statin vs. low-dose stain + ezetimibe therapy on FCT, as evaluated using optical coherence tomography.@*METHOD@#Patients who had VPs (minimum FCT 90°) and deferred from intervention in our single center from January 2014 to December 2018 were included in the trial. They were divided into the following two groups: intensive statin group (rosuvastatin 15-20 mg or atorvastatin 30-40 mg) and combination therapy group (rosuvastatin 5-10 mg or atorvastatin 10-20 mg + ezetimibe 10 mg). At the 12-month follow-up, we compared the change in the FCT (ΔFCT%) between the two groups and analyzed the association of ΔFCT% with risk factors. Fisher exact test was used for all categorical variables. Student's t test or Mann-Whitney U-test was used for analyzing the continuous data. The relationship between ΔFCT% and risk factors was analyzed using linear regression analysis.@*RESULT@#Total 53 patients were finally enrolled, including 26 patients who were in the intensive statin group and 27 who were in the combination therapy group. At the 12-month follow-up, the serum levels of total cholesterol (TC), total triglyceride, low-density lipoprotein (LDL-C), hypersensitive C-reactive protein (hs-CRP), and lipoprotein-associated phospholipase A2 (Lp-PLA2) levels were reduced in both the groups. The ΔTC%, ΔLDL-C%, and ΔLp-PLA2% were decreased further in the combination therapy group. FCT was increased in both the groups (combination treatment group vs. intensive statin group: 128.89 ± 7.64 vs. 110.19 ± 7.00 μm, t = -9.282, P < 0.001) at the 12-month follow-up. The increase in ΔFCT% was more in the combination therapy group (123.46% ± 14.05% vs. 91.14% ± 11.68%, t = -9.085, P < 0.001). Based on the multivariate linear regression analysis, only the serum Lp-PLA2 at the 12-month follow-up (B = -0.203, t = -2.701, P = 0.010), ΔTC% (B = -0.573, t = -2.048, P = 0.046), and Δhs-CRP% (B = -0.302, t = -2.963, P = 0.005) showed an independent association with ΔFCT%.@*CONCLUSIONS@#Low-dose statin combined with ezetimibe therapy maybe provide a profound and significant increase in FCT as compared to intensive statin monotherapy. The reductions in Lp-PLA2, ΔTC%, and Δhs-CRP% are independently associated with an increase in FCT.

ABSTRACT

Objective To investigate the residential radon concentration in typical areas of Hubei Province and assess the dose hazards of radon to human body. Methods According to geographical location, five cities including Wuhan, Enshi, Shiyan, Xianning and Daye were selected, and the stratified cluster sampling and monitoring were conducted in accordance with the residential building structure. From April to July, 2019, RSKS standard detectors were placed in the bedroom or living room of the tested families. After continuously sampling for three months, those detectors were returned back to the laboratory for test readings using Radosys system. Results A total of 651 detectors were deployed in 577 households of 70 communities, and 634 detectors were recovered. The recovery rate of detectors was 97.4%. The indoor residential radon concentration in Hubei Province showed a logarithmic normal distribution, with a median (25% quantile and 75% quantile) of 40.52 (29.13,64.74) Bq/m3 and an annual effective dose of 2.02 mSv. The indoor radon concentrations in Wuhan and Enshi were significantly higher than those in Shiyan, Xianning and Daye (P<0.05). The indoor radon concentrations in brick wood or civil structures were significantly higher than those in reinforced concrete structures (P<0.05), and indoor radon concentration in the first floor was significantly higher than those in other floors (P<0.05). The indoor radon concentrations after 2010 were significantly lower than those between 2001 and 2010 (P<0.05). Conclusion The number of households with indoor radon concentrations exceeding the national limit in newly-built buildings accounted for 10.1%; The indoor residential radon concentration levels of in Hubei Province were influenced by building structure, age and floor.

ABSTRACT

Objective To evaluate the value of the three-dimensional visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis. Methods A total of 8 patients with end-stage hepatic alveolar echinococcosis undergoing liver autotransplantation in Qinghai Provincial People’s Hospital from May 2013 to July 2017 were collected. All cases received preoperative abdominal CT scanning and dynamic three-phase enhanced CT scanning, and the original CT data were transferred to the human 3D visualization virtual surgical planning system. The volumes of Echinococcus multilocularis and pre-resected liver were measured using the 3D visualization reconstruction, and the relationship between the lesion and the neighboring tissues was observed. The value of the 3D visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis was assessed by comparing with the intraoperative findings. Results The 3D visualization reconstruction model clearly displayed the adjacent relationship between the lesions of end-stage hepatic alveolar echinococcosis and the neighboring tissues, and no significant difference was seen between the pre-resected liver volume in 3D visualization reconstruction model and the actually resected liver volume (t = 1.083, P > 0.05). Conclusions 3D visualization technology is feasible to develop a reasonable scheme for liver resection and vascular anastomosis for end-stage hepatic alveolar echinococcosis prior to liver autotransplantation, which may increase the success of surgery and improve the prognosis.

ABSTRACT

OBJECTIVE@#We aimed to evaluate the combined effects of a high body shape index (ABSI) and a high serum C-reactive protein (CRP) level on the incidence of ischemic stroke in a Mongolian population in China.@*METHODS@#A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) for ischemic stroke among all groups.@*RESULTS@#The multivariate adjusted HRs (95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46 (0.89-2.39) and 1.63 (0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs (95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04 (0.46-2.35), 1.06 (0.58-1.95) and 2.52 (1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant.@*CONCLUSION@#We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.

ABSTRACT

A 57-year-old male was admitted to hospital for severe headache and seizure attacks on November 6th,2016.After radiology and spinal fluid examination,he was diagnosed with viral encephalitis and treated with antiviral medicine,antibiotics and mannitol,but he was in sustained unconsciousness and weak in expectorating.The patient was given oxygen through artificial nasal after bedside tracheotomy.At 1:00 am on January 12th,2016,there was a sudden drop in blood pressure,heart rate and oxygen saturation with left lung breath sounds slightly lower than the other side.The patient was connected to a ventilator with tidal volume of 300-500 mL and airway pressure of 16-24 cmH2 O (1 cmH2 O =0.098 kPa).In the meanwhile,the left side sponge of artificial nasal was found missing.Bedside chest X-ray showed no significant atelectasis.At that time the evidence of airway foreign body aspiration was not sufficient,so no urgent bronchoscopy was performed.At 9:00 am on January 14th,2016,there was another sudden decline in oxygen saturation with diminished left lung breath sounds and decreased left thoracic activity.Since left atelectasis could not be ruled out,bedside bronchoscopy was performed.In the operation,two sponge-like objects were found at the left main bronchus and the opening of left upper lobe bronchial.Foreign body forceps were used to remove them.The foreign bodies were proved to be the left sponge of artificial nasal afterwards.Symptoms and signs caused by aspiration of foreign body in adults were widely various and depending on the nature of the foreign body,site,time and whether there was infection or not.Foreign body aspiration caused by artificial nasal sponge was rare in clinical practice.This case was a living reminder to perform bronchoscopy when foreign body aspiration was suspected.For the unconscious and elderly patient,whose history of foreign body aspiration usually could not be clearly provided,when atelectasis was suspected,bronchoscopy should be performed progressively,and more effective measures should be taken to prevent sponge of artificial nasal displacement.

ABSTRACT

OBJECTIVE@#This work aimed to compare the effect of retention and preventive caries of the pit and fissure sealant on primary teeth by using glass ionomer cements (GIC) with or without acid etching technique.@*METHODS@#In this clinical trail, 100 children aged 3-4 years old with a split-mouth design were equally divided into two groups (the left second upper and lower mandibular primary molars were present in group A, and the right second upper and lower mandibular primary molars were present in group B; each group had 200 molars). All participants were placed in pit and fissure sealant with Ketac® Molar Easymix and seated with atraumatic restorative treatmen press-finger technique in the two groups. Group A was subjected to acid etching (40 s, 35% H₃PO₄), while group B were not subjected to acid etching. GIC preservation rate, caries rate, and decayed teeth (dt) index were observed after 12 months.@*RESULTS@#After a 12-month follow-up period, the completely lost, partially losing, and losing rates of GIC in 86 children (172 second primary molars) were 83.14%, 9.88%, 6.98% in group A and 62.79%, 20.35%, and 16.86% in group B, respectively. The differences between the two groups were insignificant (P<0.05). The caries rates of groups A and B were 8.14% and 16.86%, and their dt indices were 0.08±0.31 and 1.17±0.46, respectively, thereby indicating significant difference between the two groups (P<0.05).@*CONCLUSIONS@#Using acid etching technology, the retention rate of the pit and fissure sealant increased, while its losing rate decreased. The retention effect of the GIC was improved, and the dental caries prevention effect was enhanced. Sealant processing was a self-curing procedure that sets without the external energy. Hence, this procedure is suitable for the preventive caries of primary teeth in children.

ABSTRACT

<p><b>OBJECTIVE</b>We aimed to evaluate the combined effect of a family history of cardiovascular disease (CVD) and high serum C-reactive protein (CRP) on the stroke incidence in an Inner Mongolian population in China.</p><p><b>METHODS</b>A prospective cohort study was conducted from June 2002 to July 2012, with 2,544 participants aged 20 years and over from Inner Mongolia, China. We categorized participants into four groups based on the family history of CVD and CRP levels.</p><p><b>RESULTS</b>We adjusted for age; sex; smoking; drinking; hypertension; body mass index; waist circumference; and blood glucose, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels. Compared with the group with no family history of CVD/low CRP levels, the group with family history of CVD/high CRP levels had a hazard ratio (HR) of 1.78 [95% confidence interval (CI), 1.03-3.07; P = 0.039] of stroke, and an HR of 2.14 (95% CI, 1.09-4.20; P = 0.027) of ischemic stroke. The HRs of hemorrhagic stroke for the other three groups were not statistically significant (all P > 0.05).</p><p><b>CONCLUSION</b>Participants with both a family history of CVD and high CRP levels had the highest stroke incidence, suggesting that high CRP levels may increase stroke risk, especially of ischemic stroke, among individuals with a family history of CVD.</p>

ABSTRACT

<p><b>OBJECTIVE</b>We aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population.</p><p><b>METHODS</b>A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ⋝ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage.</p><p><b>RESULTS</b>The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of < 30 U/L, 30-50 U/L and ⋝ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively (P < 0.01). The age-sex and multivariable adjusted odds ratios (95% confidence intervals) of poor prognosis comparing the top group (⋝ 50 U/L) with the lowest group (< 30 U/L) were 5.76 (2.74-12.13), 6.64 (2.05-21.52), and 6.36 (1.92-21.02). A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers.</p><p><b>CONCLUSION</b>Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.</p>

ABSTRACT

Objective · To investigate the clinical characteristics of initial peritoneal dialysis (PD) patients with different peritoneal transport status, and analyze risk factors of high peritoneal transport status in PD patients. Methods · A total of 455 consecutive PD patients newly starting PD between January 2007 to October 2015 were retrospectively analyzed. According to the results of the first sPET, patients were divided into H/HA (4h D/Pcr ≥ 0.65) and L/ LA (4h D/Pcr<0.65) groups. Clinical and biochemical characteristics between the two groups were compared. Multivariate logistic regression model was established to investigate risk factors of higher peritoneal transport status of incident PD patients. Results · The study included 372 incident PD patients. The L/LA group and H/HA group had 264 cases (71.2%) and 108 cases (28.8%) respectively. The H/HA group had higher proportion of male patients (63.0% vs 50.8%, P=0.03), lower residual renal function [RRF, (4.26±2.77) mL/min vs (5.79±4.53) mL/min, P<0.01], lower serum albumin level [(29.34±6.89) g/L vs (32.08±5.86) g/L, P=0.00], and more frequent diabetic nephropathy (19.4% vs 9.5%, P=0.00), compared with L/LA group. Univariate and multivariate logistic regression analysis showed that higher peritoneal transport status was associated with lower serum albumin level (OR=0.96, 95% CI 0.28-0.99; P=0.02), male (OR=1.92, 95% CI 1.19-3.12; P=0.00), presence of diabetic nephropathy (OR=2.52, 95% CI 1.26-5.05; P=0.00) and lower residual renal function (OR=0.90,95% CI 0.83-0.96; P=0.00). The level of hsCRP in patients with hypoalbuminemia was higher than that in patients with normal albumin level (1.69 mg/L vs 0.69 mg/L, P=0.00). Conclusion · Low and low average peritoneal transport status accounted for the majority of the patients in this study. Low serum albumin levels, male, diabetic nephropathy, RRF were risk factors of initial high peritoneal solute transport status. Chronic inflammatory status might partially explain for the correlation between hypoalbuminemia and high peritoneal solute transport status in PD patients.
