Objective:To compare the results of three kinds of glucometers and automatic biochemistry analyzer for the detection of blood glucose level of finger capillary and vein blood, and adopt linear regression to analyze their relationship.Methods: 204 patients with or without diabetes were enrolled in this study. Their finger capillary and vein blood were detected by three kinds of glucose meters and automatic biochemistry analyzer, respectively. And these data were analyzed by using linear regression and pair-t-test.Results: The comparative results revealed that the order of correlation between every glucose meters with automatic biochemistry analyzer was Accuchek higher than GT-1920 and GT-1920 higher than One Touch when the range of hematocrit (Hct) value was in 35.1%-51.6%. The correlation of Hct between every glucose meter and automatic biochemistry analyzer when the range of Hct was 25.0%-35.0% was significant higher than that when the range was 35.1%-51.6% (t=2.19,P<0.05). For finger capillary blood, the bias of One Touch was largest, while for vein blood, the bias of GT-1920 and One Touch were better. Besides, the detected results of blood glucose both of GT-1920 and One Touch were significantly higher than automatic biochemistry analyzer(t=2.34,P<0.05).Conclusion: There were better correlation between every glucose meter and automatic biochemistry analyzer, respectively, and the correlations between them can be effected by Hct. While there were still certainly difference between them.

Objective:To investigate the significance of CT imaging features in the diagnosis of first-episode paranoid schizophrenia.Methods:Forty-five patients with first-episode paranoid schizophrenia admitted to Shaoxing 7 th People's Hospital from January 2018 to January 2019 were included in the study group. An additional 40 healthy controls who received health examination were included in the control group. All participants underwent head CT scans and CT values of cerebral lobes were measured. CT imaging features of first-episode paranoid schizophrenia were analyzed. The recurrence rate of paranoid schizophrenia was calculated. The diagnostic effect of CT imaging on paranoid schizophrenia was evaluated. Results:The CT value of the frontal lobe in the study group was significantly lower than that in the control group [(33.1 ± 1.4) HU vs. (36.9 ± 2.1) HU, t = 9.914, P < 0.001]. The proportions of patients having ventricular enlargement, sulcus widening, arachnoid cyst and cisterna magna in the study group were 51.1%, 24.4%, 31.1% and 20.0% respectively, which were significantly higher than 5.5%, 2.5%, 2.5% and 2.5% respectively in the control group ( χ2 = 21.688, 8.411, 11.928, 4.675, all P < 0.05). The recurrence rate of paranoid schizophrenia in the study group was 22.2% (10/45). The CT value of the left and right frontal lobe in patients with recurrent paranoid schizophrenia was (32.1 ± 1.7) HU and (32.5 ± 1.6) HU respectively, which was significantly lower than (35.0 ± 1.9) HU and (34.9 ± 1.7) HU in patients without recurrent paranoid schizophrenia ( t = 4.348 and 3.985, both P < 0.001). Conclusion:Patients with first-episode paranoid schizophrenia have brain structural abnormalities, as manifested by ventricular enlargement, sulcus widening, arachnoid cyst, and cisterna magna. CT imaging features are of great value in the diagnosis of first-episode paranoid schizophrenia. It deserves wide popularization and has a great innovation value.

Objective:To investigate the correlation between endothelial dysfunction and cardiomyocyte apoptosis during myocardial ischemia-reperfusion.Methods:A total of 63 male rats were selected to establish the rat model of myocardial ischemia-reperfusion by the ligation of the left anterior descending(LAD)coronary artery to simulate myocardial ischemia.Rats were divided into the control group and group Ⅰb, group Ⅰa, group Ⅱb, group Ⅱa, group Ⅲb and group Ⅲa.Control rats were treated only with LAD threading without ligation.In observation group, at 30, 90, 120 min after LAD ligation(marked as Ⅰ, Ⅱ, Ⅲ group respectively), loosen the ligation to simulate ischemia-reperfusion.In the observation group, captopril sublingual injection of 0.25 mg/kg before ligation were marked as group b, and as group a with no captopril injection.The circulating endothelial cells(CEC), endothelin(ET), nitric oxide(NO)and the apoptosis rate of cardiomyocytes in each group were measured.Results:The CEC and ET levels showed a continuous upward trend, and a NO level showed a continuous downward trend from group Ⅰa to Ⅱa to Ⅲa as compared with the control group( P<0.05). After using preventive intervention of captopril, the CEC and ET levels were lower and NO levels were higher in group Ⅱb and Ⅲb than in group Ⅱa and Ⅲa, respectively( P<0.05). The apoptotic rate of cardiomyocytes was higher in group Ⅰa than in the control group, and the apoptotic rate from high to low were from group Ⅲa[(235.71±40.25)%]to group Ⅱa[(197.28±43.56)%]to group Ⅰa[(138.55±32.87)%]and to the control group[(5.81±2.02)%]( P<0.05). The apoptotic rate of cardiomyocytes was lower in group Ⅱb[(125.67±26.51)%]and Ⅲb[(124.91±33.28)%]than in group Ⅱa and Ⅲa, respectively( P<0.05). Conclusions:The ischemia-reperfusion can cause endothelial dysfunction and the apoptosis of cardiomyocytes, and there is a close relationship between the degree of this lesions and the duration of ischemia-reperfusion.While, the appropriate application of angiotensin converting enzyme inhibitor can inhibit the damage of cardiomyocytes to a some extent.

Objective To evaluate the feasibility of keeping the consistency of bladder filing by a Bladderscan ( BS ) device during radiotherapy for rectal cancer. Methods The bladder volume was measured using a BS device and recorded. To verify the reliability of the BS measurement, the urinary output was determined by a measuring glass after complete urinary discharge. The bladder volume of 42 patients determined by the planning computed tomography ( CT) scans was used as the standard urinary volume. The bladder volume was measured using the BS device before radiotherapy every day. The chief complaint urinary volume was determined as the bladder volume when a patient felt a strong urge to urinate. The controlled urinary volume was determined as the urinary output intervened by the BS device to reach the standard urinary volume. Comparison was made by t test and data was assessed by Pearson correlation analysis. Results There was no significant difference in obtained urinary volume between the BS device and the planning CT scan ( P=0?84) . The urinary volume measured by the measuring glass was correlated with that measured by the BS device ( P=0?00 ) . The ability to hold urine in all patients was gradually weakened during treatment. The controlled urinary volume had a significantly smaller decrease after 1, 2, 3, 4, and 5 weeks of treatment than the chief complaint urinary volume ( 5% vs. 21%;6% vs. 20%;6% vs. 20%, 4% vs. 21%;11% vs. 26%;all P=0?00) . Conclusions Patients have a gradually decreased urinary volume during treatment. The intervention by the BS device gives a bladder volume close to that in the planning system, which results in a consistent bladder filling.

Fluorescent carbon quantum dots ( CQDs) were synthesized by one-step hydrothermal treatment of apple juice. Experiments showed that Hg2+could quench the fluorescence of the CQDs with specificity. Based on this phenomenon, a selective and sensitive sensor was constructed for Hg2+ detection. In a NaH2 PO4-Na2HPO4 buffer solution (pH 7. 0), their fluorescence intensity showed good linear relationship with the concentrations of Hg2+ from 5 to 100 nmol/L and 1 to 50 μmol/L, respectively, with the detection limit of 2. 3 nmol/L (S/N=3). Its practical application was further demonstrated by the detection of Hg2+ in real water samples.

Objective To evaluate left ventricular systolic function by real-time three-dimension speckle tracking imaging (RT3D-STI) in coronary artery diseases (CHD) patients,to determine the clinical value of RT3D-STI in CHD.Methods 34 control subjects and 55 patients with CHD by coronary angiography were involved.Left ventricular global longitudinal strain (GLS),left ventricular global circumferential strain (GCS),left ventricular global radial strain (GRS),left ventricular global area strain (GAS) and left ventricular ejection fraction (LVEF),etc,was acquired by RT3D-STI,respectively.The parameters by RT3D-STI to diagnose CHD were analyzed.Results Compared with control group,GLS,GCS,GRS and GAS were significantly decreased in CHD group (P ＜ 0.05).The area under receiver operating characteristics (AUC) curve of GLS to diagnose CHD was 91.6％.The cutoff value,the sensitivity and Youden index of GLS were-12.5,90.3 ％ and 0.612,respectiuely.The cutoff value,the sensitivity and Youden index of GAS were-23.0,95.8％ and 0.539,respectiuely.GLS,GAS correlated well with LVEF in CHD group (r =-0.860,r =-0.926).Conclusions GLS is the most sensitivity and GAS is the most specificity in the all of strain parameters.RT3D-STI can early show the changes of left ventricular global systolic function in patients with CHD.

Objective:To investigated the correlation between vascular remodeling pattern and perforator stroke after stenting in patients with symptomatic intracranial vertebrobasilar artery stenosis.Methods:Patients with symptomatic intracranial vertebrobasilar atherosclerotic stenosis underwent stenting and high resolution magnetic resonance imaging (HR-MRI) from January 2017 to August 2020 were enrolled retrospectively. The data of demography, vascular risk factors, plaque characteristics, operation process and postoperative complications were collected. The plaque characteristics were observed by HR-MRI, and the correlation between vascular remodeling pattern and perforator stroke after stenting was analyzed.Results:A total of 41 patients were enrolled in the analysis. Their age was 60.1±8.8 years (range, 49-77 years). There were 31 males (75.6%). Among them, 21 (51.2%) were positive remodeling, 20 (48.8%) were non-positive remodeling, and 5 (12.2%) had perforator stroke after procedure. The incidence of perforator stroke in the positive remodeling group was significantly higher than that in the non-positive remodeling group (23.8% vs. 0%; P=0.048). The positive remodeling rate of the perforator stroke group was significantly higher than that of the non-perforator stroke group (100.0% vs. 44.4%; P=0.048). Conclusions:Patients with intracranial vertebrobasilar atherosclerotic stenosis and positive vascular remodeling were more likely to have perforator stroke after stenting.
