Objective To investigate the correlation between pathogens and spectrum of disease in infants with human cytomegalovirus(HCMV) active infection.Methods A total of 378 cases of HCMV infection diagnosed by the identification of HCMV IgM or PP65 antigen of HCMV.HCMV gB genotyping was carried out by nested PCR and restriction fragment length polymorphism(RFLP) in 107 cases.The results of pathogen,spectrum of disease and clinic feature were analyzed.Results In all 378 infant patients with HCMV,27.78% were systemic infection and 72.22% involved just single organ.Hepatitis,HCMV inclusion disease,thrombocytopenic purpura,pneumonia were pre- dominant with 33.07%,27.78%,13.49%,6.35% respectively.The rate of HCMV inclusion dis ease in infants younger than 2 weeks was higher than in those aged from 3 12 weeks(P ~ 0.05) and children older than 12 weeks(P＜0.01).Infants with higher rate of PP65 antigen positive cells were apt to systemic infection than those with lower rate of PP65 positive cells(P＜0.01).Infants,who were positive by detections of all three methods,were apt to systemic infection than others(P＜0.01). Moreover,infants positive of IgM and PP65 antigen were apt to systemic infection than those just positive by one of the two methods(P＜0.01).The result of gB genotype analysis in 107 cases showed 53 cases of gBⅠ,20 of gBⅡ.18 of gBⅢ.7 of gBⅠ+gBⅡ,5 of gBⅠ+gBⅢand 4 of gBⅡ+gBⅢ,and gBⅣwas not found.Conclusion HCMV could infect multiple organs and have some different clinic features.Combination of different methods can increase the sensitivity to detect the pathogen.The gBⅠgenotype is most prevalent in these infants.

Peroxisome proliferator-activated receptors (PPARs) are nuclear transcriptional factors closely related to glucose and lipid metabolism, insulin sensitivity. Activation of PPARs targets treated type 2 diabetes, obesity, hypertension and other metabolic diseases by insulin resistance. Recently, a variety of active ingredients of traditional Chinese medicines (TCMs) have been proved to activate PPARs targets for improving insulin resistance, which has attracted widespread attention at home and abroad. In this paper, we reviewed the pathological mechanisms between insulin resistance and PPARs, and summarized the active ingredients of TCMs improved insulin resistance based on PPARs targets. This paper may provide some theoretical guidance for the development of new drugs and TCMs.

OBJECTIVETo assess the significance of platelet activation in unstable angina pectoris (UA) and acute myocardial infarction (AMI), and to explore the relationship of clinical effect of Xuefu Zhuyu concentrated pill (XCP) in vivo and the serum pharmacological anti-platelet activating effect of XCP in vitro.

METHODSBy flow cytometry and special labelled antibodys to detect the whole blood platelet membranous glycoprotein CD62P and CD41/45 expressions in UA patients before and after XCP treatment, as well as those in peripheral blood of AMI rats before and after co-cultured with XCP containing serum from patients at 37 degrees C for 30 min.

RESULTSCD62P and CD41/45 expressions increased significantly in UA patients to 24.36 +/- 7.91% and 29.51 +/- 12.21% respectively. After effective treatment, they decreased to 19.57 +/- 7.22% and 20.87 +/- 8.73% respectively accompanied with increase of platelet adhesion and aggregation rate. The difference of CD62P before and after treatment was significant (P < 0.05). CD62P in blood of AMI rats was 39.73 +/- 12.36%, after being co-cultured with XCP containing serum from patients treated effectively, it reduced to 30.41 +/- 10.36% (P < 0.05), but after co-cultured with the serum from patients treated ineffectively, it showed less intervention effect (P > 0.05).

CONCLUSIONPlatelet was highly activated in UA patients and AMI rats. The consistency between clinical holistic effect of XCP and serum pharmacological effect of XCP in platelet activation inhibition reflects a good correlation between serum pharmacological effect of Chinese herbal medicine and its clinical holistic effect.

Objective To investigate the predictive value of the 40 Hz auditory steady state response (40-Hz ASSR) in the short-term prognosis of patients with brainstem stroke.Methods The 40-Hz ASSR and brainstem auditory evoked potentials (BAEP) examinations were recorded and graded from 36 patients with brainstem stroke admitted in the Neurological Intensive Care Unit (NICU). Tue end point of short-term prognostic evaluation was at the time of leaving the NICU. Tue patients with brainstem stroke were divided into the survival group (n =21) and the death group (including brain death,n = 15). The correlation between the grade of the 40-Hz ASSR or BAEP and the short-term prognosis was analyzed. Results The grade of the 40-Hz ASSR (r=0.571,P =0.000) or BAEP (r =0.441,P =0.001 ) was significantly correlated with the short-term prognosis in patients with brainstem stroke. The sensitivity,specificity and accuracy of the 40-Hz ASSR were 60.00％,100％ and 83.33％,respectively,and those for BAEP were 66. 67％,71.43％ and 69. 44％,respectively. Conclusions Tue 40-Hz ASSR has a certain short-term prognostic value in patients with brainstem stroke. The higher the grade of 40-Hz ASSR is,the more serious the illness,and the worse the prognosis.

Objective To explore the predictive value of early electroenphalography (EEG) for a malignant course in patients with large middle cerebral artery infarction (LMCAI).Methods Thirty-seven patients (20 patients with a malignant and 17 with a benign course) with stroke of >50% of the middle cerebral artery territory in early CT/MRI scan were included;Glasgow-Pittsberg Coma Scale (24 ±1 vs. 30 ±4, P =0. 003) and National Institutes of Health Stroke Scale (23 ±3 vs. 16 ±4, P =0.000) in the group with a malign course were higher than those in the group with a benign course. Early EEG was recorded within 24 h after ischemic stroke. The correlation between the change characteristics of EEG and a malignant course in patients with LMCAI was analyzed. Results The contralateral occipital background frequencies < 8 Hz (17/20 vs. 3/20, P =0.000), β frequency within the focus ≤20 Hz (19/26 vs. 7/26, P= 0-001), EEG non-reaction to stimuli (11/12 vs. 1/12, P= 0.002),slowing affecting the whole hemisphere in the lesion (17/24 vs. 7/24, P = 0. 008) and focal slowing contralateral to the lesion (16/19 vs. 3/19, P =0. 000) were significantly related with a malignant course. Whereas the contralateral occipital background frequencies ≥8 Hz (14/17 vs. 3/17, P =0. 000),β frequency >20 Hz within the focus (10/11 vs. 1/11, P =0. 001) were related with a benign course. Conclusions Early EEG has a certain predictive value for a malignant course in patients with LMCAI, and it may be used as one of the bedside monitoring approaches of LMCAI.

Objective:To investigate the role of LncRNA ZBED3-AS1 in osteoblast proliferation and differentiation in osteoporotic rats through regulating miR-339-5p/Notch 1.Methods:The rat models of sham operation (Sham) group and model (Model) group were established, and the bone mineral density (BMD) of rats was examined. Rat osteoblasts were isolated and the expression of ZBED3-AS1 and miR-339-5p was detected by qRT-PCR. The osteoblasts of rats in Sham group and Model group were divided into different groups and transfected. CCK8, alizarin red (AR-S) staining and alkaline phosphatase (ALP) staining were used to detect the proliferation and differentiation ability of cells in each group. The distribution of ZBED3-AS1 in cells was determined by FISH assay. Double luciferase report confirmed the relationship between ZBED3-AS1 and miR-339-5p as well as miR-339-5p and Notch 1.Western blot was used to detect the expression of Notch pathway related factors.Results:The bone mineral density of femur in Model group was significantly lower than that in Sham group ( P=0.0057) . Compared with Sham group, the expression of ZBED3-AS1 in osteoblasts of Model group was lower, while that of miR-339-5p was higher (all P<0.05) . Overexpression of ZBED3-AS1 could promote the proliferation and differentiation of osteoblasts, while knockdown of ZBED3-AS1 could inhibit the proliferation and differentiation of osteoblasts (all P<0.05) . ZBED3-AS1 could regulate miR-339-5p as ceRNA (all P<0.05) . Overexpression of miR-339-5p can inhibit the proliferation and differentiation of osteoblasts, which can be partially saved by overexpression of ZBED3-AS1. Notch 1 was confirmed as a target of miR-339-5p, at the same time, interfering with the expression of ZBED3-AS1/miR-339-5p can affect the expression of Notch-1 protein, and the regulation of ZBED3-AS1/miR-339-5p on osteoblasts may be realized through Notch pathway. Conclusion:ZBED3-AS1 can be used as ceRNA to regulate miR-339-5p, and then affect the proliferation and differentiation of osteoblasts in osteoporotic rats.
