Post-cardiac arrest syndrome (PCAS) is one of the most common medical emergencies in children.The fatality rate and disability rate are extremely high.Pathogenesis of PCAS remains incompletely clear,and clinical manifestation is complicated.The treatment is mainly limited to supportive care.In recent years,the phases of PCAS are defined according to the pathophysiological changes and clinical prognosis.Investigators also made some advances in the fields of pathophysiological changes and clinical treatment of brain damage and myocardial damage.For the treatment of PCAS,early therapeutic hypothermia,glucose control and seizure control,and reasonable cardiopulmonary support are promoted.In this article,we reviewed the advances in the above fields and the latest advance on the management of PCAS in foreign countries.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

Objective Using manganese enhanced MR imaging(ME-MRI)as a standard to validate the accuracy of white matter diffusion tenor tractography(DTT)with different gradients orientations in macaque monkeys.Methods Seven adult male macaque monkeys were scanned for DTY images with different number of gradients orientations.When all data were acquired.3 μl of 0.8 mol aqueous solution of MnCl2 was injected into the primary motor cortex representing forelimb for ME-MRI scanning 48 hours later.On the images of fractional anisotropy(FA),seed region for fiber tracking was chosen according to the subcortical enhanced range on ME-MRI,then the DTT fiber tracts proiecting on axial images of FA were compared with enhancement region on T1WI of ME-MRI.Results Under the calculation method for fiber tracking in the study,different motion-probing gradients orientations led to results consistent with ME-MRI for the brain above the midbrain level.All group's concordance score of fibertracking results were good.Among them,30 and 64 orientation fiber tracking results were optimal.Below the midbrain level,there was significant difference between DTT fiber tracking and ME-MRI fiber tracking. Conclusion Different motion-probing gradients orientations do not influence DTT fiber tracking.But below the midbrain level.the results of DTT fiber tracking were not reliable according to the standard results of ME-MRI fibe tracking.

Metabolic abnormalities were identified and carotid intima-media-thickness(IMT)was measured in 221 individuals at risk for metabolic syndrome(MS).The results indicated that IMT was significantly thicker in MS individuals than that in non-MS individuals(P＜0.01).And there was a tendency of progressive increase in IMT with increasing components of metabolic syndrome.

BACKGROUND:The bispectral (BIS) index is a processed electroencephalogram (EEG) parameter with extensive validation and demonstrated clinical utility. The study aimed to investigate the correlation between the BIS index and the prognosis of patients with coma in the ICU. METHODS:A total of 208 patients with coma in the ICU were enrolled in this study. According to the BIS value, the patients were divided into four groups:group I, BIS value 0 to 20; group Ⅱ, BIS value 21 to 40; group Ⅲ, BIS value 41 to 60; and group IV, BIS value greater than 60. The difference in BIS values with the differences in prognosis of patients with coma was compared between the four groups, and the prognosis of patients with coma was stratified into consciousness, coma, vegetative state, and brain death. Subsequently, the best cut-off score of BIS values calculated for determining the correlation between BIS value and mental state was proposed. RESULTS:There are no significant differences in the age and APACHE Ⅱ scores between the four groups (P>0.05). An inverse correlation was observed between BIS value and mental state (r=–0.749, P=0.00). According to the ROC curve, as BIS value was greater than 42.5, there were higher sensitivity and specificity in conscious-coma patients. CONCLUSION:BIS value is correlated with the prognosis of patients with coma in ICU, and BIS value can be a useful marker for estimating the prognosis of comatose patients.

Emerging data indicated that HCV subverts the antiviral activity of interferon (IF); however,whether HCV core protein contributes to the process remains controversial. In the present study, we examined the effect of HCV core protein on interferon-induced antiviral gene expression and whether the effect is involved in the activation and negative regulation of the Jak/STAT signaling pathway. Our results showed that, following treatment with IFN-α, the transcription of PKR, MxA and 2'-5'OAS were down-regulated in HepG2 cells expressing the core protein. In the presence of HCV core protein,ISRE-dependent luciferase activity also decreased. Further study indicated that the core protein could inhibit the tyrosine phosphorylation of STAT1, whereas the level of STAT1 expression was unchanged.Accordingly, SOCS3, the negative regulator of the Jak/STAT pathway, was induced by HCV core protein. These results suggests that HCV core protein may interfere with the expression of some interferon-induced antiviral genes by inhibiting STAT1 phosphorylation and induction of SOCS3.
