The peripheral blood T- lymphocyte percentage, lympocyte percentage in white blood cell (WBC) of mice in heat environment (45C, 15 min) were diminished, and serum corticosterone increased. Ginseng root saponins (GRS) 50, 100 mg/kg were administered ip at 15 min before the heat-stress, the suppression of peripheral blood T-lymphocyte percentage were prevented, but could not inhibit the increase ofserum corticosterone. GRS 50mg?kg-1ip could inhibit the redution of peripheral lymphocyte percentage. GRS 50mg?kg-1 ,reserpine 0.5mg? kg-1or physostigmine salicylate 0.3 mg?kg-1ip abolished the inhibiting effect of heat-stress on DTH reaction in mice.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and lethal human cancers. Cur-rent studies on the relationship between complicated type 2 diabetes mellitus (T2DM) and PDAC prognosis have demonstrated inconsis-tent results. The present study aimed to determine the relationship between complicated T2DM and the clinicopathological characteris-tics of PDAC, and evaluate whether complicated T2DM is a significant predictor for overall survival in patients with resectable PDAC. Methods: In this study, clinicopathological characteristics were observed in 136 patients who underwent surgery for PDAC at the Shengjing Hospital of China Medical University between January 2009 and February 2011. The relationship between complicated T2DM and overall survival of PDAC patients was analyzed using univariate and multivariate analyses. Results:The median age of pa-tients was 60 years (range: 35-80 years). Among the 136 patients, 76(55.9%) were male. The prevalence of complicated T2DM was 27.9%in 136 PDAC cases. Preexisting T2DM was not associated with any of the clinicopathological characteristics (all P>0.05). Uni-variate analysis showed that complicated T2DM (P=0.045), maximum diameter (P=0.011), histological differentiation (P=0.013), pT stage (P=0.034), vessel invasion (P=0.032), and pTNM stage (P=0.030) were significantly associated with the overall survival of PDAC patients. The median overall survival time was 14.2 months for T2DM patients, and 18.8 months for non-T2DM patients. In mul-tivariate analysis, complicated T2DM [hazard ratio (HR), 1.873;95%confidence interval (CI), 1.187-2.954;P=0.007], poorly differenti-ated tumor (HR, 2.647;95%CI, 1.413-4.957;P=0.002), and maximum diameter≥4.0 cm (HR, 1.699;95%CI, 1.094-2.640;P=0.018) were the independent predictors associated with poor overall survival. Conclusion:Complicated T2DM was associated with poor prog-nosis. It could be used as a prognostic predictor in patients with resectable PDAC. If confirmed, these findings may provide a novel ap-proach for individualized adjuvant therapy.

BACKGROUND:Hydroxyapatite/gel nano-composite has the same mechanical strength to the natural bone, but its ability to repair bone defects and osteogenic effect need to be confirmed by further studies.
OBJECTIVE:To explore the repair effect of hydroxyapatite/gel bionic composite in skul defects of rabbits.
METHODS: The hole-like calvarium defect models were established in rabbits, and treated with hydroxyapatite/ gel composites (hydroxyapatite/gel group), autologous skul as positive control (autologous bone group) and
nothing as negative control (blank group). The repairing condition in the skul defect areas were observed and analyzed by X-ray and CT at 4, 8, 12 weeks after implantation.
RESULTS AND CONCLUSION: After 8 weeks, X-ray assessment showed that normal-like bone tissue appeared in the defect region of the autologous bone group; in the hydroxyapatite/gel group, dense bone with similar
morphology to normal bone tissue was found in the central site of defect region, and the boundary was slightly blurred. After 12 weeks, the hydroxyapatite/gel showed blurred edge compared with autologous bone, and the center of the composite was disconnected; in the blank group, a clear and regular transmitted shadow was
observed. After 12 weeks, CT examination showed that the hydroxyapatite/gel was connected tightly with the surrounding normal bone tissue. As a new bionic composite, the hydroxyapatite/gel can achieve good effect in repairing skul defects of rabbits.

Thirty mothers of four dadys later after delivery with agalactia, whose babies needed additional milk over one third of physiological needs, or agalorrhea were chosen to take 125 g of MUYINGLE divided into 3 parts a day for observing its lactigenous effect, and thirty other agalactous mothers, who might chose any kind of traditional Chinese lactagogue foods to eat, as control group. Those subjects whose babie's additional milk was less than one fourth or half of physiolgical needs for agalactia or agalorrhea respectively after four days with MUYINGLE were effectual. The results showed that the lactagogue efficacious rate of MUYINGLE and control group were 86. 7% and 33. 3%, respectively. The lactagogue effects were significant difference between the two groups (P

[ ABSTRACT] AIM:In this study, we aim to obtain the induced pluripotent stem cells ( iPSCs) from the patients with sporadic Alzheimer disease ( AD) .METHODS:Three typical Alzheimer’ s patients were chosen, and the epithelial cells were isolated from their urine.We reprogrammed these cells into induced pluripotent stem cells by transfection of 4 factors (Oct4, Sox2, Klf4 and SV40LT) with the technique of electro-transfection.After getting these iPSCs, we continue to differentiate them into neural cells by a specific method—dual inhibition of Smad signaling.RESULTS: The primary cells from 3 AD patients were successfully reprogrammed to iPSCs, and these patients-derived iPSCs were differentiated into neural cells.There was no significant difference, during iPSCs reprogramming and neural differentiation, between cells from AD patients and normal people.CONCLUSION: The urine cells from AD patients were able to transfer to iPSCs, functional neurons and neurogliocytes.

ObjectiveTo explore the expression of monokine induced by interferon- γ(Mig) in serum and chemokine receptor 3(CXCR3)on lymphocytes of peripheral blood in children with bronchiolitis.MethodsIn this study, 55 patients with bronchiolitis in our hospital were randomly recuited, and were divided into two groups: atopic group and non-atopic group. Of the same age 26 healthy children had been enrolled randomly as control group. The level of CXCR3 expression (CD183) on lymphocytes of peripheral blood was detected by lfow cytometry in all children. The level of Mig in serum was assayed by ELISA.ResultsThe level of CD183 expression on the CD3+CD4+T lymphocytes in atopic group and non-atopic group(16.39±4.13%,14.39±3.74 %)were higher than that of control group(11.17±3.13%,P<0.05),CD183+CD4+/CD4+% in atopic group were higher than that in non-atopic group(P<0.05). The level of CD183 expression on CD3+CD8+T lymphocytes in atopic group and non-atopic group(67.18±10.57 %, 61.44±11.46 %)were higher than that of control group(51.19±5.42 %, P<0.05),CD183+CD8+/CD8+% in atopic group were signiifcantly higher than that in non-atopic group(P<0.05). The level of Mig in serum of children with bronchiolitis in atopic group and non-atopic group(99.67±35.77ng/L, 120.28±32.28ng/L)were signiifcantly higher than that in control group(63.90±15.82 ng/L,P<0.05). The level of Mig in non-atopic group was higher than that in atopic group, there was signiifcant difference(P<0.05).ConclusionsMig and CXCR3 are involved in the pathogenesis of bronchiolitis, and CXCR3 may relate to allergic factors.

Objective:To investigate the differentially expressed miRNAs in serum collected post operation and compared these miR-NAs with those collected pre-surgery among patients suffering from glioblastoma multiform (GBM) and undergoing regular clinical fol-low-up. These miRNAs may be potential biomarkers for the post-operative evaluation of patients with GBM. Methods:Forty-eight pa-tients with GBM and clinical pathological diagnosis were enrolled in this study. In the initial biomarker screening stage, total RNAs were extracted and subjected to Solexa sequencing to select miRNAs with significantly altered expression pre-and post-operation. Some of these differentially expressed miRNAs were chosen and verified through TaqMan probe-based qRT-PCR assay. A t-test was performed to determine the miRNAs that satisfied the two criteria, namely, fold change>2 and P<0.05. All of the patients were fol-lowed-up, and survival data were collected. The patients were then classified into two groups, namely, long-and short-survival groups, on the basis of the median of the miR-30e expression levels in the sera collected post-operation. Kaplan-Meier method and Log-rank test (SPSS version 19.0, IBM) were employed to determine the possible relationships between miR-30e expression levels in the sera collected post-operation and patients' overall survival. Results: Solexa revealed 63 differentially expressed miRNAs. Four miRNAs, namely, miR-26b, miR-30e, miR-129-3p, and miR-206, were selected on the basis of previous and present findings. These miRNAs were then verified in the RT-qPCR phase. Among these miRNAs, only miR-30e was significantly upregulated post-operation. The serum miR-30e expression level post-operation was not significantly associated with the overall survival of the patients. A low miR-30e expression level corresponded to prolonged survival. Conclusion:miR-30e was upregulated in the sera collected post-operation from patients with GBM. This miRNA may be negatively related to the tumor load of these patients. The miR-30e expression level in the serum col-lected post-surgery serum was not significantly associated with overall survival. Therefore, miR-30e may serve as a novel potential non-invasive biomarker for the post-operative evaluation of patients with GBM.
