Idiopathic thrombocytopenic purpura is a common hemorrhagic disease of child,and the chronic type of it is easier to recur.This paper introduces Professor SHI Yu-min's experience in treating chronic idiopathic thrombocytopenic purpura with methods of strengthening kidney,benefiting qi and activating blood flow combining with tonification and regulation.In addition,this paper expounds Prof.SHI's characteristics and laws in herbal prescription.And a case is presented.

Hydrogen is an ideal energy due to its high conversion efficiency, recyclability and nonpolluting nature. Compared with conventional methods, biological hydrogen production process is found to be less energy intensive and more environmental friendly, and nowadays more and more attentions are being paid on its fermentative way. A survey of fermentative bio-hydrogen production process was provided, followed by its new approaches in the future development.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Objective To evaluate the effects of endogenous NO on the chemosensitivity of human breast cancer cell. Methods MCF-7 cells were cultured as monolayer, incubated with cytokine IL-1β. The pro-duction of NO was detected by NO assay. The expression of iNOS protein was measured by Western blotting. Establishing control group and experimental group, the chemosensitivity of MCF-7 cells incubated by L-NMMA and L-Arg to ADM and 5-Fu was studied by MTT assay. Results There was a positive correlation of dose-dependence between NO production and IL-1β concentration. MCF-7 cells expressed plenty of iNOS by induetion of IL-1β. There was no significant difference on iNOS whether L-NMMA and L-Arg existed or not. Incubating MCF-7 cells with 0. 5 μmol/L or 1 μmol/L ADM, the survival rate of experiment group was remarkablely decreased(P < 0.05) ; L-NMMA significantly increased survival rate of experiment group(P < O. 05) ; L-Arg decreased survival rate of experiment group(P < 0.05). Conclusion The induction of IL-113 in MCF-7 cells can increase the production of endogenous NO, which increases MCF-7 cells' sensitivity to chemotherapy.

Objective To evaluate a modified liver hanging maneuver(retrohepatic tunnel of the IVC) in patients undergoing hemihepatectomy.Methods Twenty-four patients undergoing hemihepatectomy were divided into two groups:modified liver hanging maneuver group(n=12)and Pringle's maneuver group(n=12).The amount of intraoperative bleeding,operation time,postoperative liver function,liver function recovery and complications were compared between the two groups.Reset All operation were performed successfully and there were no difference in the time of operation etween the two groups.There was a difierence in the amount of mean intraoperative blood loss between the two groups.It was(160±40)ml in liver hanging group and(560±120)ml in Pringle's group(P＜0.01).Liver function recovery measured on postoperative day 3 and day 7 was better in liver hanging groupthan that in Pringle's group(P＜0.01).The volume of postoperative peritoneal serous fluid dranage was significantly less in liver hanging group(P＜0.01).Conclusion The modified liver hanging maneuver is useful for hemihepatectomy.

Objective Preparing platelet rich gel through two-times centrifugal technique and co-culturing chondrocytes with PRG, then observing the proliferation and gene expression of chondrocytes, in order to provide a favorable way to prepare tissue engineering cartilage. Methods Centrifugating venous blood of rabbit through two-times centrifugal technique to obtain platelet rich plasma( PRP) ,then detecting the concentration of various growth factor in PRP. Admixing PRP with chondrocytes of rabbit and activating them with activator. After co-culti-vation,the proliferation of chondrocytes through MTT method and expression of ACAN,CollagenⅡand SOX-9 through realtime-PCR were ob-served,and compared with common cultured chondrocytes. Results The concentrations of PDGF-AB,TGF-β1,IGF-1 and VEGF in PRG were significantly higher than those in blood(P<0. 05). After co-cultivation, the proliferation rate of chondrocytes and the expression of ACAN,Collagen Ⅱ and SOX-9 were significantly higher than that of common cultured chondrocytes(P<0. 05). Conclusion Co-culturing chondrocytes with PRG is able to promote the proliferation and gene expression of chondrocytes. We considered that it is a excellent method to construct tissue engineering cartilage.

To explore the diagnostic values of miRNA141 and miRNA375 for prostate cancer.The expressions of miRNA141 and miRNA375 in serum samples from 30 prostate cancer (PCA) patients,40 benign prostatic hyperplasia patients and 50 normal controls were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).The expression of miRNA141 in tissue samples from prostate cancer was 13.4±7.2 folds of that from benign prostatic hyperplasia while the expression of miRNA375 in tissue samples from prostate cancer was 28.4 ± 10.3 folds of that from benign prostatic hyperplasia.The differential expression of miRNA141 and miRNA375 in sera of prostate cancer suggested that miRNA141 and miRNA375 might be potential tumor markers in clinical practice.
