Abatract:Objective To study the relationship of the processes of chronic hepatitis B infection with the degree of depression and the level of serum Brain-derived neurotrophic factor (BDNF).Methods 126 patients with different processes of CHB infection were divided into 3 groups,which were asymptomatic HBV carriers (ASC group),liver cirrhosis (LC group)and hepatic cell carcinoma (HCC group).40 healthy volunteers were selected as normal control.Questionnaire was used to study demographic data and the degree of depression was assessed by using Hamilton Depression Rating Scale (HAMD-17).The levels of the serum BDNF were detected by ELISA.Results The ratio of divorced or widowed in LC and HCC groups was higher than that of the control (χ2 = 6.354,11.972;P < 0.01).Severity of depression in ASC,LC and HCC groups was higher than that of the control (χ2 = 16.151,42.150,49.636;P <0.01).Severity of depression in ASC and LC group was lower than that of HCC group (χ2 = 14.345,28.772;P <0.01).The role of BDNF (x ±s,ng/ml)in ASC,LC,HCC and control group were 11.10±3.26,8.66 ± 3.11,7.39 ±2.52 and 12.18±2.59.The levels of serum BDNF in LC and HCC group was lower than ASC group and the control (P <0.01).The process of CHB infection had positive correlation with the score of HAMD (r=0.719,P <0.01),but had negative correlation with thelevels of serum BDNF (r=-0.504,P <0.01). There was negative correlation relationship between the score of HAMD and the levels of serum BDNF (r=-0.526,P <0.01).Conclusion The process of CHB infection can obviously aggravate the degree of depression,and reduce the levels of BDNF gradually.The levels of serum BDNF can be suggested as a psychological laboratory reference basis for the CHB pa-tients with depression.It is expected to improve the level of clinical diagnosis and treatment in CHB with depression.

Objective:The aim of this study was to investigate the prognostic value of vitamin B12 as the non-invasive biomarker to predict long-term rebleeding rate in cirrhotic patients with esophagogastric varices.Methods:From Dec 1, 2016 to Dec 31, 2017, cirrhotic patients with esophagogastric varices who had been admitted to Zhongshan Hospital affiliated to Fudan University were enrolled. All these patients received endoscopic treatment to prevent variceal rebleeding. The serum vitamin B12 and folic acid levels were measured in all of them. The receiver operating characteristic (ROC) analysis, Kaplan-Meier analysis, univariate and multivariate cox regression analysis were conducted to explore the value of vitamin B12 in predicting 3-year variceal rebleeding in cirrhotic patients with esophagogastric varices after endoscopic treatment.Results:115 patients were included. The ROC curve analysis indicated that the optimal cutoff value of vitamin B12 for 3-year variceal rebleeding was 567.25 pg/ml. According to the cut-off value, the patients were divided into high-level vitamin B12 group ( n=49) and low-level vitamin B12 group ( n=66). Compared with the low vitamin B12 group, the high vitamin B12 group had lower albumin level, less male (63.3% vs 80.3%), and higher 3-year rebleeding rate ( P<0.05). Cox analysis showed that vitamin B12 and platelet were independent prognostic factors for 3-year rebleeding in patients with variceal bleeding. Conclusions:Elevated peripheral blood vitamin B12 predicts a higher risk of long-term rebleeding in patients with liver cirrhosis and esophagogastric varices.

OBJECTIVETo study the factors affecting extracellular glycerol (Gly) in patients with severe traumatic brain injury (STBI).

METHODSPerilesional extracellular Gly and cerebral blood flow (CBF) in 53 patients with STBI were consecutively monitored. Simultaneously, the intracranial pressure (ICP) and cerebral perfusion pressure (CCP) were monitored. The hourly minimum of CCP and CBF and the hourly maximum of ICP levels were matched with the hourly Gly. Gly values were divided into several groups according to regional ICP (less than 15 mm Hg or larger than 15 mm Hg), CCP (less than 70 mm Hg or larger than 70 mm Hg), CBF (less than 50 AU or 50-150 AU) and the outcomes (death or persistent vegetative state group, severe or moderate disability group, and good recovery group).

RESULTSIn comparison with the severe or moderate disability group, the Gly concentration of the death or persistent vegetative state group increased significantly, but CBF and CCP decreased significantly. In comparison with the good recovery group, the Gly concentration of the severe or moderate disability group increased significantly, but CBF and CCP decreased significantly. The Gly concentrations in patients with ICP larger than 15 mm Hg, CCP less than 70 mm Hg and CBF less than 50 AU were respectively higher than those of patients with ICP less than 15 mm Hg, CCP larger than 70 mm Hg and 50 AU less than CBF less than 150 AU. In patients with diffuse axial injury, the mean Gly concentration was (201.17+/-55.00) micromol/L, which was significantly higher than that of the patients with epidural hematoma (n equal to 7, 73.26+/-8.37, P less than 0.05) or subdural hematoma (n equal to 9, 114.67+/-62.88, P less than 0.05), but it did not increase significantly when compared with those in patients with contusion(n equal to 24, 167.48+/-52.63).

CONCLUSIONGly can be taken as a marker for degradation of membrane phospholipids and ischemia, which reflects the severity of primary or secondary insult.

OBJECTIVETo study the effect of mild hypothermia on glucose metabolism and glycerol of brain tissue in patients with severe traumatic brain injury (STBI) using clinical microdialysis.

METHODSThirty-one patients with STBI(GCS less than or equal to 8) were randomly divided into hypothermic group(Group A) and control group(Group B). Microdialysis catheters were inserted into the cerebral cortex of perilesional and normal brain tissue. All samples were analyzed using CMA microdialysis analyzer.

RESULTSIn comparison with the control group, lactate/glucose ratio(L/G), lactate/pyruvate ratio(L/P) and glycerol(Gly) in perilensional tissue were significantly decreased; L/P in normal brain tissue was significantly decreased. In control group, L/G, L/P and Gly in perilensional tissue were higher than that in normal brain tissue. In the hypothermic group, L/P in perilensional tissue was higher than that in relative normal brain.

CONCLUSIONSMild hypothermia protects brain tissues by decreasing L/G, L/P and Gly in perilensional tissue and L/P in "normal brain" tissues. The energy crisis and membrane phospholipid degradation in perilensional tissue are easier to happen after traumatic brain injury, and mild hypothermia protects brain better in perilensional tissue than in normal brain tissue.

OBJECTIVETo observe the effects of polydatin on learning and memory and cyclin-dependent kinase 5 (Cdk5) kinase activity in the hippocampus of rats with chronic alcoholism.

METHODSForty rats were randomly divided into 4 groups: control group, chronic alcoholism group, low and high polydatin group. The rat chronic alcoholism model was established by ethanol 3.0 g/(kg · d) (intragastric administration). The abstinence scoring was used to evaluate the rats withdrawal symptoms; cognitive function was measured by Morris water maze experiment; Cdk5 protein expression in the hippocampus was detected by immunofluorescence; Cdk5 kinase activity in the hippocampus was detected by liquid scintillation counting method.

RESULTSThe abstinence score, escape latency, Cdk5 kinase activity in chronic alcoholism group rats were significantly higher than those of control group (P < 0.05). The abstinence score, escape latency in high polydatin group rats were significantly lower than those of chronic alcoholism group (P < 0.05); Cdk5 kinase activity in high and low polydatin group rats was significantly lower than that of chronic alcoholism group( P < 0.05); immunofluorescence showed that the Cdk5 positive cells of chronic alcoholism group were significantly increased compared with control group (P < 0.05), and the Cdk5 positive cells of polydatin groups were significantly decreased compared with chronic alcoholism group ( P < 0.05).

CONCLUSIONPolydatin-reduced the chronic alcoholism damage may interrelate with regulation of Cdk5 kinase activity.

Objective To investigate the feasibility of the adaptive cardio sequence prospective ECG-gated dual-source CT coronary angiography (CTCA).Methods Thirty one patients underwent prospective ECG-gated dual-source CTCA. The patients were divided into two groups: group A, heart rate ≤ 75 times / minutes, 70% of R-R interval was chose; group B, heart rate> 75 times / minutes, 40% of R-R interval was chose. Two experienced radiologists assessed the image quality of 15 segments of coronary arteries in a double blinded fashion in a four score scale. Student t test was used to compare the image quality between two groups. CT dose index(CTDIvol) and effective dose(ED) were also calculated for both groups. Results 437 segments of coronary arteries in 31 patients were included this analysis, 408 segments (93.4%) had assessable image quality, while 29 segments (6.6%) had non assessable image quality. Of 226 segments in group A, 12 segments (5.3%) had non assessable image quality; however, 17 segments (8.1%) of 211 segments in group B had non assessable image quality. The average score of image quality was 3.57±0.64 in 31 patients. There was no statistical difference for mean image quality of group A (3.65±0.39) and group B (3.41±0.43)( t=1.62,P=0.12 ) . There was a statistical difference for mean image quality for segment 10 on a per segment basis ( t = 3.8 ,P＜0.05). CTDIvol and ED were (18.88±5.04) mGy and (4.31±1.05) mSv, respectively.Conclusion Adaptive cardio sequence prospective ECG-gated dual source CT can acquire assessable image quality of coronary artery with lower radiation dose to the patients, which has the potential to be a routine CTCA technique.
