ABSTRACT

Objective To investigate the heart rate control and related influencing factors of patients with coronary heart disease and arrhythmia in Qinghai in 2019. Methods Clinical data of 263 patients with coronary heart disease and arrhythmia in our hospital in 2019 were retrospectively analyzed. According to their resting heart rate control status at 6 months after discharge, the patients were divided into a well-controlled heart rate group (n=151) and a poorly controlled heart rate group (n=112). The clinical characteristics of patients with different heart rate control status were compared, and influencing factors of heart rate control were analyzed. Results Among patients with coronary heart disease and arrhythmia in Qinghai in 2019, atrial arrhythmia had a higher incidence rate (55.51%), and the main types of arrhythmia were atrial premature beat. The rate of good heart rate control of patients at 6 months after discharge was 57.41%. The heart rate control status was related to the resting heart rate at discharge, age, smoking status, treatment methods, type of coronary heart disease, CCS grade, NYHA classification, hypertension, diabetes mellitus, cardiac enlargement, use of beta blocker and awareness of heart rate control target at discharge (t=32.370, P2=26.300, P2=45.690, P2=15.161, P2=67.500, P2=18.788, P2=10.228, P=0.006; χ2=78.769, P2=66.374, P2=51.165, P2=43.360, P2=40.315, P<0.001), and the difference was statistically significant. Smoking, coronary artery bypass grafting, myocardial infarction, diabetes mellitus, non-use of beta blockers, and poor awareness of heart rate control were independent risk factors for poor heart rate control in patients with coronary heart disease and arrhythmia (P<0.05). Conclusion In 2019, the rate of good heart rate control in patients with coronary heart disease and arrhythmia in Qinghai is above the average level, and the health education on heart rate control relate knowledge for high-risk groups should be strengthened.

ABSTRACT

Objective:To investigate the association of body weight and body mass index (BMI) with bone mineral density (BMD) and osteoporotic risk in elderly men with type 2 diabetes mellitus (T2DM).Methods:210 elderly male patients with T2DM admitted to the Department of Endocrinology of the First Hospital of Changsha from June 2017 to May 2018 were selected as the research objects. The height, weight and bone mass index (BMI) were measured. BMDs of the left hip [including femoral neck (FN), greater trochanter (G.T.), intertrochanter (InTro), and total hip (TH)] and lumbar spine (LS) were measured in 210 elderly male patients with T2DM by dual-energy X-ray absorption method. Patients were divided into three groups according to BMI: the overweight group (24.0 kg/m 2≤BMI<28.0 kg/m 2), the obesity (BMI≥28.0 kg/m 2) group, and the normal group (18.5 kg/m 2≤BMI<24.0 kg/m 2). The influence of body weight and BMI on BMD and osteoporotic risk in these elderly men with T2DM was analyzed. Results:The BMDs in various sites of the hip of the overweight group and obesity group were higher compared with those in the normal weight group ( P<0.05). There was a positive correlation between weight and BMI with BMDs in various sites of the hip femoral neck (including FN, G. T., InTro, and TH) ( r=0.239-0.427, P<0.05). All patients were divided into different tertiles (T1-T3) stratified by weight and BMI respectively. The BMDs in various sites of the hip increased with tertiles stratified by weight ( P<0.05). The TH-BMD also increased with tertiles stratified by BMI ( P<0.05). The odd ratios ( OR) were calculated using T3 as the control group and T1 as the case group, using T2 as the control group and T1 as the case group, respectively. The osteoporotic risks of T1/T3, T1/T2 at FN stratified by weight were significantly increased by 4.50 times ( OR=4.50, 95% CI: 1.41-14.35) and 9.27 times ( OR=9.27, 95% CI: 2.03-42.30); The osteoporotic risks of T1/T3, T1/T2 at TH were significantly increased by 3.25 times ( OR=3.25, 95% CI: 1.10-9.59) and 8.50 times ( OR=8.50, 95% CI: 1.85-38.99). The osteoporotic risks of T1/T3, T1/T2 at FN stratified by BMI respectively were significantly increased by 4.13 times ( OR=4.13, 95% CI: 1.28-13.25) and 5.58 times ( OR=5.58, 95% CI: 1.53-20.42); while the osteoporotic risks of T1/T3, T1/T2 at TH stratified by BMI were not significantly increased ( P>0.05). There was no statistically significant difference in BMDs and the osteoporotic risks of the LS among T1, T2, and T3, regardless of stratified by weight or BMI ( P>0.05). Conclusions:For elderly males with T2DM, weight and BMI are important factors affecting BMDs in the hip, and also affecting the osteoporotic risks of the hip, especially that of FN. Osteoporotic risks of the FN decrease with the increase of weight and BMI within a certain range.

ABSTRACT

Objective:To investigate the clinical value of conventional ultrasound combined with contrast-enhanced ultrasound (CEUS) in diagnosis of chromophobe renal cell carcinoma (ChRCC).Methods:We retrospectively analyzed the ultrasound features of 40 cases with ChRCC which were confirmed by operation and pathology from January 2012 to January 2018 in our hospital. The site, shape, size, capsule, internal echo and blood supply of the lesions were observed by routine ultrasound. Then CEUS showed the modality of enhancement, including the arrival time, peak time, peak intensity, distribution and the washout time.Results:Among the 40 cases, 38 cases were single, 2 cases were multiple, 17 cases were left kidney, 22 cases were right kidney, 1 case was double kidney. The tumors were located in the upper part of the kidney in 8 cases (20.0%), the lower part of the kidney in 9 cases (22.5%), and the middle part of the kidney in 23 cases (57.5%). One of the tumors was located in the right renal pelvis, and the lesion invaded the renal capsule in 11 cases (27.5%). The tumor was round, quasi round or oval, with clear boundary in 35 cases (87.5%), unclear boundary in 5 cases (12.5%), and the maximum diameter was 2.0-11.2 (5.1±0.8)cm. The lesions were hypoechoic in 23 cases (57.5%), isoechoic in 7 cases (17.5%), slightly hyperechoic in 7 cases (17.5%), cystic and solid mixed echo in 3 cases (7.5%), homogeneous echo in 23 cases (57.5%), heterogeneous echo in 17 cases (42.5%), and calcification in 5 cases (12.5%). Color Doppler flow imaging (CDFI) showed that blood vessels could be seen around the lesions, and no obvious blood flow signal was detected in 15 cases (37.5%) of the lesions; few star shaped blood flow signals could be detected in 12 cases (30%) of the lesions, short strip shaped blood flow signals could be detected in 7 cases (17.5%) of the lesions, and abundant blood flow signals could be seen in 6 cases (15%) of the lesions. Four patients underwent contrast-enhanced ultrasound examination at the same time. The lesions began to strengthen rapidly and evenly at the same time in the renal cortex, showing slightly low enhancement, and disappeared earlier than the renal cortex, showing a " fast forward and fast backward" perfusion mode. No tumor thrombus in draining vein, perirenal tissue and lymph node metastasis were found in all cases.Conclusions:Conventional ultrasound show ChRCC to be poor blood supply of solid tumors in the renal parenchyma, most of which are hypoechoic or isoechoic, with clear boundaries. CEUS show the lesions taking on high wash-in and wash-out, low enhancement than the surrounding renal cortex. These features are helpful for preoperative ultrasound diagnosis of ChRCC.

ABSTRACT

Reactive nitrogen species (RNS) affects intracellular redox balance and induces post-translational modification of proteins. Moreover, RNS, as the signal molecule, participates in the transduction of cellular signals under physiological conditions. However, excessive RNS can induce nitrosative stress and then damage cells, and thereby may play a role in the tumor initiation and progression. Thus, we discussed the role of RNS under physiological conditions and the tumor microenvironment, which may provide some novel ideas for the development of new drugs and the treatment of diseases.

ABSTRACT

Purpose@#This research was designed to investigate how miR-542-5p regulates the progression of hyperglycemia and hyperlipoidemia. @*Materials and Methods@#An in vivo model with diabetic db/db mice and an in vitro model with forskolin/dexamethasone (FSK/DEX)-induced primary hepatocytes and HepG2 cells were employed in the study. Bioinformatics analysis was conducted to identify the expression of candidate miRNAs in the liver tissues of diabetic and control mice. H&E staining revealed liver morphology in diabetic and control mice. Pyruvate tolerance tests, insulin tolerance tests, and intraperitoneal glucose tolerance test were utilized to assess insulin resistance. ELISA was conducted to evaluate blood glucose and insulin levels. Red oil O staining showed lipid deposition in liver tissues. Luciferase reporter assay was used to depict binding between miR-542-5p and forkhead box O1 (FOXO1). @*Results@#MiR-542-5p expression was under-expressed in the livers of db/db mice. Further in vitro experiments revealed that FSK/DEX, which mimics the effects of glucagon and glucocorticoids, induced cellular glucose production in HepG2 cells and in primaryhepatocytes cells. Notably, these changes were reversed by miR-542-5p. We found that transcription factor FOXO1 is a target of miR-542-5p. Further in vivo study indicated that miR-542-5p overexpression decreases FOXO1 expression, thereby reversing increases in blood glucose, blood lipids, and glucose-related enzymes in diabetic db/db mice. In contrast, anti-miR-542-5p exerted an adverse influence on blood glucose and blood lipid metabolism, and its stimulatory effects were significantly inhibited by sh-FOXO1 in normal control mice. @*Conclusion@#Collectively, our results indicated that miR-542-5p inhibits hyperglycemia and hyperlipoidemia by targeting FOXO1.

ABSTRACT

BACKGROUND: Development of tissue engineering is of great social and economic significance. Understanding the basic research strength of China in the main subfields of tissue engineering can provide reference for the optimization of resources allocation and for the formulation of corresponding development strategies. OBJECTIVE: To evaluate the basic research strength of China in the main subfields of tissue engineering. METHODS: PubMed was searched for basic research and top basic research articles in the subfields of tissue engineering (including bone and cartilage, nerve, blood vessel, liver, skin, heart, and eye tissue engineering) in the world, the United States and China. By comparing with the global average and American, Chinese basic research strength in the main subfields of tissue engineering was evaluated with indicators including the number of papers, the growth rate of papers, and the number and proportion of top papers. RESULTS AND CONCLUSION: (1) The number of basic research papers published by Chinese institutions in the subfields of bone and cartilage tissue engineering, nerve tissue engineering, vessel tissue engineering, liver tissue engineering, skin tissue engineering, cardiac tissue engineering and eye tissue engineering was 4 487, 3 551, 2 869,1 328,1 185,1 088 and 689, respectively, accounting for 10%—15% of worldwide papers in corresponding subfields. The amount of papers published by Chinese institutions was nearly half of that published by institutions of the United States for the first five subfields, but only 32.1% and 37.8% of that published by institutions of the United States for the latter two subfields. (2) The annual growth rate of papers published by Chinese institutions was 19.3%, 19.5%, 18.2%, 14.6%, 21.8%, 19.6% and 19.6%, respectively, for the above seven subfields, all of which were obviously higher than that of the global average and the United States. (3) The number of top papers published by Chinese institutions was 36, 31, 33, 24,15, 24 and 12, and the proportion of top papers published by Chinese institutions was 0.8%, 0.9%, 1.2%, 1.8%, 1.3%, 2.2% and 1.7%, respectively, all of which were obviously lower than that of the global average and the United States. (4) China has published relatively more papers on bone and cartilage tissue engineering, nerve tissue engineering and vessel tissue engineering, and relatively less papers on cardiac tissue engineering and eye tissue engineering. The amount of papers published by Chinese institutions has been growing rapidly in each of the seven main subfields of tissue engineering, with the speed of growing being obviously higher than that of the global average and the United States. China has published a certain amount of top papers in each of the seven subfields, while the proportion of top papers for China is obviously lower than that of the global average and the United States.

ABSTRACT

OBJECTIVE@#To study the pharmacokinetic characteristics, clinical effect, and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in children with acute lymphoblastic leukemia (ALL).@*METHODS@#A prospective study was performed on children with ALL who cyclophosphamide, cytarabine, and 6-mercaptopurine were used for consolidation therapy. PEG-rhG-CSF (PEG-rhG-CSF group) or rhG-CSF (rhG-CSF group) was injected after chemotherapy. The plasma concentration of PEG-rhG-CSF was measured, and clinical outcome and safety were observed for both groups.@*RESULTS@#A total of 17 children with ALL were enrolled, with 9 children in the PEG-rhG-CSF group and 8 children in the rhG-CSF group. In the PEG-rhG-CSF group, the peak concentration of PEG-rhG-CSF was 348.2 ng/mL (range 114.7-552.0 ng/mL), the time to peak was 48 hours (range 12-72 hours), and the half life was 14.1 hours (range 11.1-18.1 hours). The plasma concentration curve of PEG-rhG-CSF was consistent with the mechanism of neutrophil-mediated clearance. Compared with the rhG-CSF group, the PEG-rhG-CSF group had a significantly shorter median time to absolute neutrophil count (ANC) recovery (P0.05).@*CONCLUSIONS@#The pharmacokinetic characteristics of PEG-rhG-CSF in children with ALL receiving consolidation chemotherapy are consistent with the mechanism of neutrophil-mediated clearance, with a short half life and fast recovery of ANC, and there are no significant differences in safety between PEG-rhG-CSF and rhG-CSF.

ABSTRACT

OBJECTIVE@#To analyze the clinical efficacy and side effects of reduced-dose of cyclophosphamide combined cyclosporine A for severe aplastic anemia(SAA) children.@*METHODS@#Ten pediatric patients with SAA from January 2008 to May 2012 were enrolled. All the patients were treated with reduced dose of cyclophosphamide combined cyclosporine A. The dose of cyclophosphamide was 30 mg/(kg·d)×4 d, the dose of cyclosporine A gradually increased >15 mg/L accroding to the blood concentration.@*RESULTS@#The median follow-up time of the 10 pediatric patients was 100 months (6-126 months). Among 10 children with SAA, 4 cases achieved complete response(CR), 3 cases obtained partial response (PR) and the overall response rate was 70%, the remaining 3 cases showed no response (NR). One refractory patient treated by cyclophosphamide was progressed to paroxysmal nocturnal hemoglobinuria(PNH) at 25 months and was dead at 42 months after therapy.@*CONCLUSION@#The results show that reduced-dose cyclophosphamide (30 mg/kg·d for 4 consecutive days) combinated with CsA (initial dose 4 mg/kg·d, and drugvallery concentration >150 ng/ml) can make 7 of 10 children with severe aplastic anemia achieve complete response or partial response, and this regimen may be the second line regimen selected for some SAA children.

ABSTRACT

Objective@#To analyze the efficacy of revascularization in oldest-old patients with acute ischemic stroke (AIS).@*Methods@#The clinical data of AIS patients receiving recanalization therapy in Beijing Hospital from January 2010 to July 2018 were retrospectively reviewed. Among 141 patients, there were 34 cases aged ≥80 years (oldest-old group) and 107 cases aged<80 years (old group).The clinical characteristics and outcomes of two groups were analyzed and compared.@*Results@#The proportions of patients with atrial fibrillation and coronary heart disease in oldest-old group were high than those in the old group [61.8% (21/34) vs. 33.6%(36/107), χ2=8.47, P<0.01; 58.8% (20/34) vs. 32.7% (35/107), P<0.01, respectively]; while there were no significant differences in other risk factors between two groups (P>0.05). The National Institute of Health Stroke Scale Score (NIHSS) was higher in the oldest-old group than that in old group [16 (13,21) vs. 11 (6,16), Z=3.74, P<0.01]. In the etiological classification, cardiogenic embolism was the main cause in the oldest-old group (58.8%, 20/34), while large artery atherosclerosis was the main cause in the old group (46.7%, 50/107, χ2=12.11, P<0.01). There were no significant differences between the two groups in the methods of recanalization [intravenous thrombolysis were 35.3% (12/34) and 48.6% (52/107); endovascular therapy were 52.9% (18/34) and 36.4% (39/107), bridging therapy were 11.8% (4/34) and 15.0% (16/107), respectively; χ2=2.93,P=0.23] and the time from onset to treatment [195(154, 269) min vs. 215 (153,280)min, Z=1.03, P>0.05]. The 3-month independent (modified Rankin score ≤2) rate was lower in the oldest-old group than that in the old group [35.3% (12/34) vs. 56.1%(60/107), χ2=4.46, P<0.05). The 3-month mortality was higher in the oldest-old group than that in the old group [29.4% (10/34) vs. 8.4%(9/107), χ2=9.76, P<0.01]. There was a tendency of increased incidence of symptomatic intracranial hemorrhage (SICH) in the oldest-old patients compared to the old patients [11.8% (4/34) vs. 7.5% (8/107), P>0.05].@*Conclusion@#The conditions of AIS patients aged ≥80 years are more serious than those of patients aged<80 years, with higher mortality and lower functional improvement rate after recanalization treatment.

ABSTRACT

Background@#Diabetes can complicate hypertension management by increasing the risk of cardiovascular disease (CVD) and all-cause mortality. Studies targeting diabetes detection in hypertensive individuals demonstrating an increased risk of diabetes are lacking.We aimed to assess the performance of hemoglobin A1c (HbA1c) and its cut-off point in detecting diabetes in the abovementioned population. @*Methods@#Data from 4,096 community-dwellers with hypertension but without known diabetes were obtained from the Study on Evaluation of iNnovated Screening tools and determInation of optimal diagnostic cut-off points for type 2 diaBetes in Chinese muLti-Ethnic (SENSIBLE) study; these data were randomly split into exploration (70% of the sample) and internal validation (the remaining 30%) datasets. The optimal HbA1c cut-off point was derived from the exploration dataset and externally validated using another dataset from 2,431 hypertensive individuals. The oral glucose tolerance test was considered the goldstandard for confirming diabetes. @*Results@#The areas under the ROC curves for HbA1c to detect diabetes were 0.842, 0.832, and 0.829 for the exploration, internal validation, and external validation datasets, respectively. An optimal HbA1c cut-off point of 5.8% (40 mmol/mol) yielded a sensitivity of 76.2% and a specificity of 74.5%. Individuals who were not diagnosed as having diabetes by HbA1c at 5.8% (40 mmol/mol) had a lower 10-year CVD risk score than those diagnosed as having diabetes (P = 0.01). HbA1c ≤ 5.1% (32 mmol/mol) and ≥ 6.4% (46 mmol/mol) could indicate the absence and presence of diabetes, respectively. @*Conclusions@#HbA1c could detect diabetes effectively in community-dwellers with hypertension.

ABSTRACT

Objective@#To determine the factors influencing insomnia and construct early insomnia warning tools for rescuers to informbest practices for early screening and intervention.@*Methods@#Cluster sampling was used to conduct a cross-sectional survey of 1,133 rescuers from one unit in Beijing, China. Logistic regression modeling and R software were used to analyze insomnia-related factors and construct a PRISM model, respectively.@*Results@#The positive rate of insomnia among rescuers was 2.74%. Accounting for participants' age, education, systolic pressure, smoking, per capita family monthly income, psychological resilience, and cognitive emotion regulation, logistic regression analysis revealed that, compared with families with an average monthly income less than 3,000 yuan, the odds ratio ( ) values and the [95% confidence interval ( )] for participants of the following categories were as follows: average monthly family income greater than 5,000 yuan: 2.998 (1.307-6.879), smoking: 4.124 (1.954-8.706), and psychological resilience: 0.960 (0.933-0.988). The ROC curve area of the PRISM model (AUC) = 0.7650, specificity = 0.7169, and sensitivity = 0.7419.@*Conclusion@#Insomnia was related to the participants' per capita family monthly income, smoking habits, and psychological resilience on rescue workers. The PRISM model's good diagnostic value advises its use to screen rescuer early sleep quality. Further, advisable interventions to optimize sleep quality and battle effectiveness include psychological resilience training and smoking cessation.

ABSTRACT

OBJECTIVE@#To study the significance of CD20 combined with white blood cell (WBC) count at diagnosis in the prognosis assessment in children with B-lineage acute lymphoblastic leukemia (ALL).@*METHODS@#A retrospective analysis was performed on the medical data of 821 B-ALL children who were treated with CCLG-ALL2008 regimen from April 2008 to April 2015. Their survival status was followed up.@*RESULTS@#Among the 821 children, 547 (66.6%) were negative, while 274 (33.4%) were positive for CD20 expression. Among 694 children with WBC50×10/L (higher WBC count), the 5-year EFS rates was 64.3%±7.7% and 53.7%±5.5% for CD20 positive and negative patients respectively (P=0.135); the 5-year OS rate was 81.4%±6.4% and 58.6%±5.6% for CD20 positive and negative patients respectively (P=0.022); CD20 positive expression was an independent protective factor for OS (HR=0.367, P=0.016).@*CONCLUSIONS@#In children with B-ALL who are treated with CCLG-ALL2008 regimen, those with CD20 positive expression in lower WBC count at diagnosis have a poor prognosis; however, those with CD20 positive expression in higher WBC count at diagnosis have a better long-time survival.

ABSTRACT

Acute lymphoblastic leukemia (ALL) is a common pediatric cancer. The second malignant neoplasms (SMNs) in long-term survivors of pediatric ALL are relatively rare. Herein we report a 10-year-old girl who was diagnosed as primitive neuroectodermal tumor (PNET) 5 years after the initial diagnosis of ALL with radiotherapy-free treatment. PNET is an exceedingly rare neoplasm in SMNs of survivors of childhood ALL. It is predisposed to be misdiagnosed and the pathogenesis is unclear. The outcome is poor. Long-term follow-up is necessary for the survival children of ALL.

ABSTRACT

OBJECTIVE@#To study the long-term efficacy of CCLG-ALL2008 protocol used for treatment of childhood acute lymphoblastic leukemia (ALL).@*METHODS@#Nine hundred and forty children with newly diagnosed ALL from January 2008 to April 2015 were treated with CCLG-ALL2008 protocol. Overall survival (OS) and event-free survival (EFS) rates were estimated by the Kaplan-Meier method. Cox proportional hazards model was used for analyses of prognostic factors.@*RESULTS@#Among the 940 newly diagnosed ALL patients, 570 patients were male, and 370 patients were female, the median age of onset was 5 years old (from 1 to 15 years old). The complete reaction rate (CR) was 96.7%. Survival analysis of 916 ALL patients with CR estimated by follow up [ (median follow up period 64 months (from 3 to 123 months) ] showed that, the expected 10 year OS rate was (78.6±1.5)% and the EFS rate was (66.0±1.8)%. The long-term OS rate of standard risk, intermediate risk and high risk patients was (93.0±1.5)%, (77.6±2.7)%, and (59.3±3.7)%, respectively, and the long-term EFS rate in standard risk, intermediate risk and high risk patients was (84.2±2.2)%. (67.8±2.9)%, and (42.1±3.9)% respectively. 10 year OS rate in B-ALL patients (79.8±1.6)% was significantly higher than that in T-ALL patients (53.5±6.3)% (P<0.01). Among of all the patients, patients 201 (21.9%) relapsed, the median relapse time was 19 months (from 2 months to 81 months). The 10 year EFS rate was (81.7±3.7)% in the patients with MRD rate <0.01% after induction therapy, which was significantly higher than that in the patients with MRD rate>0.01% (48.4±9.8)%.@*CONCLUSION@#The therapeutic efficacy of the CCLG-ALL2008 protocol is closed to the level of supior study group in the world. Risk stratification can improve the outcome for childhood ALL. Immunophenotyping shows the outcome of B-ALL is better than that of T-ALL. MRD negative patients after induction therapy shows better prognosis compared with that of MRD positive patients.

ABSTRACT

Objective:To analyze the efficacy of revascularization in oldest-old patients with acute ischemic stroke (AIS).Methods:The clinical data of AIS patients receiving recanalization therapy in Beijing Hospital from January 2010 to July 2018 were retrospectively reviewed. Among 141 patients, there were 34 cases aged ≥80 years (oldest-old group) and 107 cases aged<80 years (old group).The clinical characteristics and outcomes of two groups were analyzed and compared.Results:The proportions of patients with atrial fibrillation and coronary heart disease in oldest-old group were high than those in the old group [61.8% (21/34) vs. 33.6%(36/107), χ 2=8.47, P<0.01; 58.8% (20/34) vs. 32.7% (35/107), P<0.01, respectively]; while there were no significant differences in other risk factors between two groups ( P>0.05). The National Institute of Health Stroke Scale Score (NIHSS) was higher in the oldest-old group than that in old group [16 (13,21) vs. 11 (6,16), Z=3.74, P<0.01]. In the etiological classification, cardiogenic embolism was the main cause in the oldest-old group (58.8%, 20/34), while large artery atherosclerosis was the main cause in the old group (46.7%, 50/107, χ 2=12.11, P<0.01). There were no significant differences between the two groups in the methods of recanalization [intravenous thrombolysis were 35.3% (12/34) and 48.6% (52/107); endovascular therapy were 52.9% (18/34) and 36.4% (39/107), bridging therapy were 11.8% (4/34) and 15.0% (16/107), respectively; χ 2=2.93, P=0.23] and the time from onset to treatment [195(154, 269) min vs. 215 (153,280)min, Z=1.03, P>0.05]. The 3-month independent (modified Rankin score ≤2) rate was lower in the oldest-old group than that in the old group [35.3% (12/34) vs. 56.1%(60/107), χ 2=4.46, P<0.05). The 3-month mortality was higher in the oldest-old group than that in the old group [29.4% (10/34) vs. 8.4%(9/107), χ 2=9.76, P<0.01]. There was a tendency of increased incidence of symptomatic intracranial hemorrhage (SICH) in the oldest-old patients compared to the old patients [11.8% (4/34) vs. 7.5% (8/107), P>0.05]. Conclusion:The conditions of AIS patients aged ≥80 years are more serious than those of patients aged<80 years, with higher mortality and lower functional improvement rate after recanalization treatment.

ABSTRACT

Objective:To investigate the protective effects of Elabela(ELA) on the renal injury of db/db mice and its possible mechanism.Methods:Sixteen eight-week-old male db/db mice were intraperitoneally injected with ELA(5 mg·kg -1·day -1) or equivalent normal saline( n=8) for 8 weeks. Eight age-matched male db/m mice received equivalent normal saline injection as normal control. At the end of the experiment, blood and urine samples were obtained for HbA 1C and urinary albumin/creatinine(ACR) measurements. Immunohistochemistry was used to observe the expression of ELA. Histopathological changes in kidney tissue were observed by HE staining and Masson staining. The levels of collagen type Ⅳ(Col-Ⅳ) and transforming growth factor-β1(TGF-β1) as well as Yes-associated protein(YAP) phosphorylation in kidney tissue were examined by western blot. Results:Immunohistochemistry results showed that ELA expression was decreased in the renal tissue of db/db mice as compared with that of db/m mice( P<0.05). After ELA treatment, ACR and blood pressure were markedly decreased in db/db mice( P<0.05), but without significant changes in the body weight and HbA 1C. Renal tubular epithelial cells edema, basement membrane thickening, and increased collagen fiber in db/db were improved by ELA administration. Compared with db/m mice, the levels of TGF-β1 and Col-Ⅳ expression, as well as YAP phosphorylation were significantly increased in renal tissue of db/db mice(0.98±0.08 vs 0.68±0.10, 1.10±0.14 vs 0.51±0.08, 3.38±0.72 vs 0.81±0.13, all P<0.05), which were down-regulated after ELA administration(0.80±0.06, 0.51±0.05, 2.21±0.22, all P<0.05). Conclusion:ELA may improve the renal injury of db/db mice by regulating the signaling pathway of YAP, thereby delaying the development of diabetic nephropathy.
