ABSTRACT

OBJECTIVE@#To investigate the changes in the functional connectivity (FC) in the right insula between migraine without aura (MWoA) and healthy controls by using resting-state functional magnetic resonance imaging (rs-fMRI), and to observe the instant alteration of FC in MWoA during electroacupuncture (EA) stimulation at Shuaigu (GB8).@*METHODS@#A total of 30 patients with MWoA (PM group) and 30 healthy controls (HC group) underwent rs-fMRI scans. The PM group underwent a second rs-fMRI scan while receiving EA at GB8. The right insula subregions, including the ventral anterior insula (vAI), dorsal anterior insula (dAI) and posterior insula (PI), were selected as the seed points for FC analysis.@*RESULTS@#Aberrant FC, including dAI with right postcentral gyrus, PI with left precuneus, was found among PM before EA (PMa), PM during EA (PMb) and HC. Meanwhile, decreased FC between dAI and the right postcentral gyrus was found in the PMa compared to the HC and PMb. Increased FC between the PI and left precuneus was found in the PMa compared to the HC and PMb. Correlation analysis showed that the FC value of the right postcentral gyrus in PMa was negatively correlated with the scores of Hamilton Rating Scale for Depression and Hamilton Rating Scale for Anxiety. The FC value of the left precuneus in PMa was positively correlated with the visual analogue scale score.@*CONCLUSION@#The alteration of FC between the right insula subregions and multiple brain regions may be an important index for MWoA. EA at GB8 was able to adjust the FC between the right insula subregions and parietal lobe, namely, the right dAI and right postcentral gyrus, and the right PI and left precuneus, thereby rendering an instant effect in the management of MWoA.

ABSTRACT

OBJECTIVE@#To investigate the auxiliary diagnostic value of serum adenosine deaminase (ADA) in acute leukemia (AL) at clinical test.@*METHODS@#123 AL patients hospitalized in Zhejiang hospital from November 2018 to March 2020 were enrolled as the observation group, and 98 healthy people in the same period were randomly enrolled as the control group. AL patients were divided into two groups: 77 acute myeloid leukemia (AML) patients for AML group and 46 acute lymphoblastic leukemia (ALL) patients for ALL group. The levels of adenosine deaminase (ADA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH) and homocysteine (Hcy) in serum of the patients were detected, and the correlation of ADA with these items was analyzed. Receiver operating characteristic curve (ROC) was used to analyze the clinical diagnostic value of ADA, Yoden index was used to confirm the best cut-off point.@*RESULTS@#The serum ADA level in AL patients was significant higher than that in control group (P < 0.05). The results of Pearson correlation analysis showed that there was a significant positive correlation of ADA with Hcy, ALT, AST, GGT, LDH in AML group (r = 0.47, r = 0.28, r = 0.37, r = 0.22, r = 0.55); and also there was a significant positive correlation of ADA with GGT in ALL group (r = 0.54). In AML group, the maximum area under ROC curve was 0.761 (P = 0.00), 95% confidence interval was 0.682-0.841, sensitivity was 54.50%, specificity was 98.90%, and the best cut-off point was 17.1 U/L. In ALL group, the maximum area under ROC curve was 0.785, 95% confidence interval was 0.694-0.877, sensitivity was 65.90%, specificity was 84.00%, and the best cut-off point was 13.45 U/L.@*CONCLUSION@#The detection of ADA in serum can be used as an auxiliary examination in patients with AL, which can provide a certain value for the diagnosis of the disease.

ABSTRACT

Tubular dentin is of great significance in the process of tooth tissue and tooth regeneration, because it is not only the structural feature of primary dentin, but also can affect the tooth sensory function, affect the differentiation of dental pulp cells and provide strong mechanical support for teeth. Scaffold is one of the three elements of tissue engineering dentin regeneration. Most experiments on dentin regeneration involve the study of the microstructure and mechanical properties of the scaffold. The microstructure and mechanical characteristics of scaffold materials have important effects on the differentiation and adhesion of odontoblast, it can directly affect the tissue structure of regenerated dentin.

ABSTRACT

ObjectiveOnly few studies have been published of the effect of microvascular invasion (MVI) on long-term prognosis of liver resection (LR) for multiple hepatocellular carcinomas (mHCCs). Therefore, we investigate the efficacy of MVI on long-term prognosis of the patients undergoing LR formHCCs.MethodsThe clinical data of 505 patients undergoing LR for mHCCs in the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University between March 2009 and March 2015 were retrospectively analyzed. Patients were divided into the MVI(+) group (n=279)and MVI (-) group (n=226), and146 patients in MVI (+) group and 124 patients in MVI (-) group received adjuvant transarterial chemoembolization (TACE). The Kaplan-Meier approach was used for survival analysis and the Cox proportional-hazards regression model was used forthe risk factors of long-term survival rate.ResultsThe early recurrence rate of MVI (+) group was significantly higher than that of MVI (-) group (60.4% vs 40.5%, P<0.01), and the 1-, 3-, 5-year overall survival rate of MVI (+) group was significantly lower than those in MVI (-) group (70.5%, 47.4%, 33.4% vs 86.6%, 66.8%, 50.1%, P<0.05). Among MVI (+) patients, the early recurrence rate and 1-, 3-, 5-year overall survival rate in the adjuvant TACE group were better than those in the control group (early recurrence rate 41.3% vs 39.3%, P<0.05; 1, 3, 5 year overall survival rate 92.8%, 72.5%, 53.1% vs 78.6%, 59.5%, 47.3%, P<0.05). Multivariate Cox model indicated that the Alpha-foetoprotein (AFP) level, maximum tumor diameter/minimum tumor diameter, MVI and adjuvant TACE were independent risk factors for early recurrence (HR=1.48, 1.51, 1.34, 0.76, P<0.05); maximum tumor diameter, intraoperative blood transfusion, MVI and adjuvant TACE were independent risk factors for postoperative overall survival (HR=1.75, 1.75, 1.36, 0.68, P<0.05).ConclusionMVI is a risk factor for early recurrence and poor long-term prognosis after LR for mHCCs. For mHCCs with MVI, adjuvant TACE after LR could reduce the early recurrence rate and improve the long-term survival rate.

ABSTRACT

@#Objective    To compare the effect of aspirin+ticagrelor and aspirin+clopidogrel on graft patency one year after coronary artery bypass grafting (CABG). Methods    A total of 67 patients who received CABG in our department from January 2014 to September 2017 were included in this study (52 males and 15 females). They were randomly divided into a group A (aspirin+clopidogrel) and a group B (aspirin+ticagrelor). There were 34 participants in the group A (28 males and 6 females) and 33 patients in the group B (24 males and 9 females). All patients were invited for clinical follow-up and 64-slice multislice computed tomography angiography (MSCTA) analysis in 1 year postoperatively. Cardiovascular events, bleeding events and other adverse events were followed up. Results    Four patients were lost to follow-up. Two patients died. A total of 61 patients (48 males and 13 females) completed coronary CTA, and 31 in the group A (25 males and 6 females) and 30 in the group B (23 males and 7 females). The total number of bridged vessels was 156 (59 internal thoracic artery bridges and 97 great saphenous vein bridges), including 79 in the group A (31 internal thoracic artery bridges and 48 great saphenous vein bridges) and 77 in the group B (28 internal thoracic artery bridges and 49 great saphenous vein bridges). Graft patency rate 1 year post CABG was 82.3% (65/79) in the group A and 92.2%(71/77) in the group B (P>0.05). Artery graft patency rate 1 year post CABG was 96.8% (30/31) in the group A and 96.4%(27/28) in the group B (P>0.05). Saphenous vein graft patency rate 1 year post CABG was 72.9% (35/48) in the group A  and 89.8% (44/49) in the group B (P<0.05). Multivariable analysis with binary logistic regression showed ticagrelor use reduced graft occlusion (OR=0.282, 95%CI 0.093 to 0.862, P<0.05). There was no significant difference in adverse events between the two groups. Conclusion    Compared with clopidogrel plus aspirin, ticagrelor added to aspirin after CABG may enhance the saphenous graft patency without the excess risk of bleeding 1 year post CABG.

ABSTRACT

OBJECTIVE@#To analyze the correlations between the incidence of rubella and meteorological factors over the same period and previous periods including 1, 2, 3 and 4 year ago (defined according to Chinese medicine Yunqi theory of "pestilence occurring after 3 years") and establish the rubella-meteorological forecast models for Beijing area, China.@*METHODS@#Data regarding the incidence of rubella between 1990 and 2004 from Beijing Center for Disease Control and Prevention, and the meteorological variables including daily average temperatures, daily average wind speeds, average precipitations, average relative humidity, average vapor pressures and average low cloud covers between 1986 and 2004 were collected from the Beijing Meteorological Observatory. Descriptive statistics and back-propagation artificial neural network for forecast model's establishment were adopted for data analysis.@*RESULTS@#The average temperature and relative humidity have a great contribution (100%) to the rubella morbidity. But the combination of other meteorological factors contributed to improve the accuracy of rubella-meteorological forecast models. The forecast accuracy could be improved by 76% through utilizing a combination of meteorological variables spanning from 3 years ago to the present rather than utilizing data from a single year or dating back to more earlier time than 3 years.@*CONCLUSIONS@#There is a close relationship between the incidence of rubella and meteorological variables in current year and previous 3 years. This finding suggests that rubella prediction would benefit from consideration to previous climate changes.

ABSTRACT

The therapeutic effects of endothelial progenitor cells (EPCs) on ischemic stroke have been extensively studied in recent years. However, the differences in early EPCs and endothelial outgrowth cells (EOCs) are still unclear. Clarifications of their respective properties and specific functioning characteristics contribute to better applications of EPCs in ischemic diseases. In this review, we discuss cellular origin, isolation, culture, surface markers of early EPCs and EOCs and relevant applications in neurological diseases. We conclude that EOCs possess all haracteristics of true endothelial progenitors and have potent advantages in EPC-based therapies for ischemic diseases. A number of preclinical and clinical applications of EPCs in neurological diseases are under study. More studies are needed to determine the specific characteristics of EPCs and the relevant mechanisms of EPCs for neurological diseases.

ABSTRACT

OBJECTIVE: To prepare compound aspirin and esomeprazole magnesium enteric-coated pellet capsules and evaluate the drug release in vitro/in vivo. METHODS: The aspirin pellet cores were prepared by using extrusion-spheronization method, and the esomeprazole magnesium-containing drug pellets were prepared with fluidized bed. By using fluidized bed coating method, the two kinds of drug-containing pellets were respectively coated with enteric layer to obtain enteric-coated pellets. After determining the loading capacity by measuring drug content, the two kinds of drug-containing pellets were filled into No.1 capsules. In vitro release was evaluated by measuring release percentage. The in vivo release behavior was evaluated by determination of pharmacokinetic parameters in rats. RESULTS: The cumulative release percentage of the two drugs was less than 5% in 2 h in 0.1 mol·L-1 hydrochloric acid solution. The cumulative release percentage of aspirin was more than 70% in 45 min in pH 6.8 PBS and it was more than 80% in 30 min for esomeprazole magnesium. Aspirin was metabolized to salicylic acid in plasma and its main pharmacokinetic parameters were as follows:t1/2=9.47 h, MRT0-∞=14.43 h, tmax=3.00 h, ρmax=51.34 mg·L-1, AUC0-24=703.39 mg·h·L-1, AUC0-∞=860.52 mg·h·L-1. The pharmacokinetic parameters for esomeprazole magnesium were as follows:t1/2=3.72 h, MRT0-∞=7.44 h,tmax=1.50 h, ρmax=2.71 mg·L-1, AUC0-24=11.89 mg·h·L-1, AUC0-∞=13.79 mg·h·L-1. CONCLUSION: The formulation of compound enteric-coated pellet capsules is reasonable, and the preparation technology has good reproducibility. The drug release is located in the intestinal tract, thus esomeprazole magnesium can antagonize the gastrointestinal side effects of aspirin and aspirin can produce better antithrombotic effect.

ABSTRACT

The VEGF in low oxygen conditions are reported to prolong the survival of malignant cell, and thus this gene has a critical role in tumor growth and invasion as well as development of malignant tumor. We aimed to assess the association between the six common SNPs and the risk of osteosarcoma, and their association with environmental factors. 176 subjects with osteosarcoma and 176 gender- and sex-matched healthy control individuals were enrolled into our study. The VEGF -2578C/A, -1156G/A, +1612G/A, +936C/T, -634G/C and -460T/C gene polymorphisms were determined using a polymerase chain reaction-restriction fragment length polymorphism [PCR-RFLP] assay according to manufacturer's instructions By conditional logistic regression analysis, AA and CA+AA genotypes of VEGF -2578C/A were associated with significant increased risk of osteosarcoma compared with CC genotype, and the ORs [95%CI] were 2.32 [1.18-4.60] and 1.68 [1.07-2.64], respectively. Moreover, individuals with CC and TC+CC genotypes of VEGF-460T/C had significant increased risk of osteosarcoma compared with those carrying with the TT genotype, and ORs [95%CI] were 2.15 [1.10-4.21] and 1.60 [1.0-2.58], respectively. By stratified analysis, we did not find statistically significant associated between VEGF -2578C/A and -460T/C gene polymorphisms and cancer risk by stratification analysis. Our results suggested that VEGF -2578C/A and -460T/C gene polymorphisms may be association with an increased risk of osteosarcoma

ABSTRACT

<p><b>BACKGROUND</b>Spinocerebellar ataxia type 3 (SCA3) is the most common subtype of SCA worldwide, and runs a slowly progressive and unremitting disease course. There is currently no curable treatment available. Growing evidence has suggested that nerve growth factor (NGF) may have therapeutic effects in neurodegenerative diseases, and possibly also in SCA3. The objective of this study was to test the efficacy of NGF in SCA3 patients.</p><p><b>METHODS</b>We performed an open-label prospective study in genetically confirmed adult (>18 years old) SCA3 patients. NGF was administered by intramuscular injection (18 μg once daily) for 28 days consecutively. All the patients were evaluated at baseline and 2 and 4 weeks after treatment using the Chinese version of the scale for assessment and rating of ataxia (SARA).</p><p><b>RESULTS</b>Twenty-one SCA3 patients (10 men and 11 women, mean age 39.14 ± 7.81 years, mean disease duration 4.14 ± 1.90 years, mean CAG repeats number 77.57 ± 2.27) were enrolled. After 28 days of NGF treatment, the mean total SARA score decreased significantly from a baseline of 8.48 ± 2.40 to 6.30 ± 1.87 (P < 0.001). Subsections SARA scores also showed significant improvements in stance (P = 0.003), speech (P = 0.023), finger chase (P = 0.015), fast alternating hand movements (P = 0.009), and heel-shin slide (P = 0.001).</p><p><b>CONCLUSIONS</b>Our preliminary data suggest that NGF may be effective in treating patients with SCA3.</p>
