ABSTRACT
Objective:To observe any effect of transcranial direct current stimulation (tDCS) on the cognition of stroke survivors and the integrity of their white matter fibers.Methods:Thirty persons with post-stroke cognitive impairment (PSCI) were randomly divided into an experimental group ( n=15) and a control group ( n=15). In addition to basic drug therapy and routine cognition training, the experimental group received 20 minutes of tDCS daily, 5 days per week for 3 weeks, while the control group received sham tDCS stimulation. Before and after the treatment, both groups′ cognitive functioning was evaluated using the mini-mental state examination (MMSE) and the Montreal cognitive assessment scale (MoCA). Their ability in the activities of daily living (ADL) was quantified using the modified Barthel index (MBI). Diffusion tensor imaging (DTI) was employed to observe any changes in the integrity of their white matter fibers. Results:The average MMSE, MOCA and MBI scores of both groups had improved significantly after the treatment, but the improvement in the experimental group was significantly greater than among the controls. The average fractional anisotroposy value of the affected inferior fronto-occipital fasciculus in both groups was positively correlated with the group′s average MMSE score and MoCA score.Conclusion:tDCS can effectively improve the cognition and functioning in the activities of daily living of stroke survivors. Its mechanism may be related to improving the integrity of the white matter fibers involved.

ABSTRACT
Hyperglycemia is a common complication of critical patients. Currently, clinical assessment of the changes in the blood glucose of critical patients is mainly based on the intermittent monitoring of peripheral blood glucose at a certain time point. This method cannot get the true blood glucose fluctuation, and it is more difficult to find asymptomatic hyperglycemia and hypoglycemia, so the guiding value of blood glucose control is limited. Arterial blood is the most accurate sample of blood glucose monitoring, so it is urgent to ensure the accuracy of arterial blood sample. A continuous arterial blood glucose monitoring equipment was independently developed by general surgical intensive care unit (ICU) of the First Affiliated Hospital of Nanjing Medical University, and National Utility Model Patent of China was obtained. It could greatly improve the efficiency of medical staff, and provide accurate and dynamic statistic data that would be an important basis for doctors' clinical decision-making. The continuous arterial blood glucose monitoring equipment was mainly composed of arterial pressure measuring monitor, program-controlled dynamic blood glucose meter, wire, electric switch, integrated collecting syringe, electric clip, rotary electric bracket, and blood glucose test strips, etc., which could be continuously and dynamically monitor patient blood glucose levels and perform various additional value-added functions such as automatic recording and alarming.
ABSTRACT
Objective@#To explore the correlation between the severity of gastroesophageal reflux cough and degree of gastroesophageal reflux.@*Methods@#A cross-sectional investigation was carried out. Data of 174 cases of chronic cough were collected in Children's Hospital of Fuzhou from March 2009 to December 2016. The esophageal 24 hours pH value dynamic monitoring was used to detect gastric acid reflux index. Cases with abnomal results were divided into mild, moderate and severe groups according to severity of reflux and that of day and night cough symptoms, respectively. They were also divided into infant (1-3 years old), preschool (4-6 years old), and school age (>7 years old) groups according to age. Comparative analysis between groups by chi-square test and rank sum test were performed. Correlation analysis was used to analyze the correlation between cough severity and gastroesophageal reflux index.@*Results@#A total of 174 patients with chronic cough, including 115 males and 59 females, aged from 1 to 15 years with an average age of (8.5±2.3) years, and (1.6±0.8) years of disease duration were enrolled. Among them, 129 cases (74.1%) were positive for esophageal reflux test and 45 cases (25.9%) with no obvious pathological gastroesophageal reflux. Patients with positive esophageal reflux test were divided into severe (n=37, 28.7%), moderate (n=23, 17.8%), and mild (n=69, 53.5%). There was no significant difference in the distribution of gastroesophageal reflux in each age group. (The proportions of mild, moderate and severe reflux in infants were 45.0% (9/20), 25.0% (5/20), and 30.0% (6/20), respectively. The proportions of mild, moderate and severe reflux in preschool children were 53.3% (32/60), 16.7% (10/60), 30.0% (18/60), respectively. The proportions of mild, moderate and severe reflux in school age children were 57.1% (28/49), 16.3% (8/49), 26.5% (13/49), respectively χ2=1.204, P=0.877). There was no correlation between age group and gastroesophageal reflux (r=-0.065, P=0.489).The severity of nighttime cough was positively correlated with percentages of distal esophagus pH≤4 in time, recumbent pH≤4 in time, and DeMeester score<14.72 (r=0.689, 0.621, and 0.707 respectively, all P<0.05). There was no statistically significant correlation between the severity of nighttime cough symptoms and percentage of standing pH≤4 in time (r=0.113, P>0.05). There were no statistically significant correlation between the severity of daytime cough and all gastroesophageal reflux markers (all P>0.05).@*Conclusion@#The severity of nocturnal symptoms of gastroesophageal reflux cough is related to the degree of gastroesophageal reflux, to which clinical pediatricians should pay attention.
ABSTRACT
Objectives To analyze and understand the risk factors related to HIV new infections among men who have sex with men (MSM).Methods A longitudinal observational study among MSM was conducted to collect information on HIV related behaviors and sero-conversion.Univariate and multivariate generalized estimating equations (GEE) were used to discuss the risk factors for HIV new infection.Results A total number of 4 305 MSM were followed during 2013-2015.Among those self-reported MSM who are seeking partners on the Interner tended to have higher proportion on receptive anal intercourse and consistent condom use during anal intercourse than the subgroups seeking their partners in gay bars or bathrooms.HIV incidence among followed MSM during the study period appeared as 4.3/100 person years,with adjusted RR (aRR) of HIV infection for receptive anal intercourse as group 2.20 (95％ CI:1.49-3.24) times than that of insertion anal intercourse group.Those who used rush-poppers (aRR=1.55,95％CI:1.10-2.17),unprotected anal intercourse (aRR=2.24,95％ CI:1.62-3.08),and those with syphilis infection (aRR=2.95,95％ CI:2.00-4.35) were also risk factors for HIV new infections.After controlling other factors,the relationship between the ways of seeking partners and HIV new infection was not statistical significant.Conclusion Risk factors for HIV new infection among MSM appeared complex and interactive,suggesting that further studies are needed to generate tailored strategies for the prevention of HIV epidemic among MSM population.

CD4(+)CD25(+)CD127(dim/-) regulatory T cells (Tregs) have been implicated in suppressing T cell immune responses to hepatitis B virus (HBV), but the inhibition mechanism has not being clear yet. This study investigated the effects of soluble FGL2 (sFGL2) secreted by Tregs on immune suppression in chronic HBV-infected patients. We verified that sFGL2 protein and mRNA were highly expressed in Tregs. The separated Tregs by using magnetic beads from peripheral blood mononuclear cells (PBMCs) in 20 patients with chronic hepatitis B were co-cultured with PBMCs at a ratio of 1:3 with anti-CD3 stimulating antibody or FGL2 blocking antibody. The proliferation index of CD8(+)T cells after blocking FGL2 was higher than that in blank group (3.58±0.18 vs. 3.28±0.17, P=0.034) in 18 of 20 samples, and lower than that in CD3 stimulation group (3.82±0.19, P=0.026) in 16 of 20 samples. The IFN-γ secreted in the mixed culture in the absence of Tregs was higher than that in the culture in the presence of Tregs, but it could be abolished by FGL2 blocking antibody. These results suggest that sFGL2 protein secreted by Tregs suppresses the proliferation and function of CD8(+) T cells in chronic hepatitis B.
