As modern medicine getting deeply to understand ever-detailed anatomy,structure and animal mechanics of the patellofemoral joint, excessive lateral pressure syndrome, a very common patellofemoral disorder, has been reacquainted by the clinicians. On account to the complexity and variety of the etiology and the mechanism of the pain, still, there are many difficulties and arguments on the exact description of the clinical symptoms and the establishment of a universally accepted diagnostic criteria. Accurately grasping different causes, pathomechanisms and developmental stages of the disease would be especially important. As a result, rational choice of the pertinent procedures become the clinical lynchpin. This paper reviews domestic and international pertinent literatures in the past 10 years, and provide an overview of the latest study of anatomy, biomechanic, pathomechanism and clinical experience, anticipating to offer help on standardizing the diagnosis and treatment of ELPS.

To explore the protective effect of Angelica sinensis polysaccharides(ASP) on subacute renal damages induced by D-galactose in mice and its mechanism. Male C57BL/6J mice were randomly divided into 3 groups, with 10 mice in each group. The D-galactose model group was subcutaneously injected with D-galactose (120 mg x kg(-1)), qd x 42; the ASP + D-galactose model group was intraperitoneally injected with ASP since the 8th day of the replication of the D-galactose model, qd x 35; and the normal control group was subcutaneously injected with saline at the same dose and time. On the 2nd day of after the injection, the peripheral blood was collected to measure the content of BUN, Crea, UA, Cys-C; paraffin sections were made to observe the renal histomorphology by HE staining; senescence-associated β-g-alactosidase (SA-β-Gal) stain was used to observe the relative optical density (ROD) in renal tissues; transmission electron microscopy was assayed to observe the renal ultrastructure; the renal tissue homogenate was prepared to measure the content of SOD, GSH-PX, MDA; the content of AGEs and 8-OH-dG were measured by ELISA. According to the result, compared with the D-galactose model group, the ASP + D-galactose model group showed obviously decreases in the content of BUN, Crea, UA, Cysc, AGES, 8-OH-dG, the number of hardening renal corpuscle, renal capsular space and renal tubular lumen, ROD of SA-β-Gal staining positive kidney cells, mesangial cells, basement membrane thickness, podocyte secondary processes fusion and MDA and increases in the number of normal renal corpuscle, ribosome and rough endoplasmic reticulum in podocytes, the activity of SOD and GSH-PX. In Conclusion, A. sinensis polysaccharides can antagonize kidney subacute damages induced by D-galactose in mice.

OBJECTIVETo explore the biological mechanisms underlying Angelica sindsis polysaccharide (ASP) -induced aging of human-derived leukemia stem cells (LSCs) in vitro.

METHODAcute myelogenous leukemia stem cells were isolated by magnetic activated cell sorting (MACS). The ability of LSC proliferation treated by various concentration of ASP(20-80 mg · L(-1)) in vitro for 48 hours were tested using cell counting Kit-8 ( CCK8) , colony forming were evaluated by methylcellulose CFU assay. The ultra structure changes of AML CD34+ CD38- cells were analyzed by transmission electron microscopy. The aging cells were detected with senescence-β-galactosidase Kit staining. Expression of aging-related p53, p21, p16, Rb mRNA and P16, Rb, CDK4 and Cyclin E protein were detected by quantitative reverse transcription polymerase chain reaction( qRT-PCR) and Western blotting, respectively.

RESULTThe purity of the CD34 + CD38 - cells is (91.15 ± 2.41)% after sorted and showed good morphology. The proliferation of LSC was exhibited significantly concentration-dependent inhibited after exposure to various concentration of ASP. Treated by 40 mg · L(-1) ASP for 48 hours, the percentage of positive cells stained by SA-β-Gal was dramatically increased (P < 0.01) and the colony-formed ability has been weakened (P < 0.01). The observation of ultrastructure showed that cell heterochromatin condensation and fragmentation, mitochondrial swelling, lysosomes increased in number. Aging-related p53, p21, p16, Rb and P16, Rb were up-regulated, protein regulatory cell-cycle CDK4 and Cyclin E were down-regulated. ASP may induce the senescence of LSCs effectively in vitro, P16-Rb cell signaling pathway play a significant role in this process.

CONCLUSIONASP can induce human leukemia stem cell senescence in vitro, the mechanism involved may be related to ASP regulation P16-Rb signaling pathways.

Leukemia is a type of malignant tumors of hematopoietic system with the abnormal increased immature leukemia cells showing metastasis and invasion ability. Liver is one of the main targets of the leukemia cells spread to, where they may continue to proliferate and differentiate and cause liver function damage, even liver failure. Our previous studies showed that Angelica polysscharides (APS), the main effective components in Angelica sinensis of Chinese traditional medicine, was able to inhibit the proliferation and induced differentiation of the leukemia cells, however, its effect on the liver during the treatment remains elucidated. In the present study, the human leukemia NOD/SCID mouse model were established by implantation human leukemia K562 cells line, then the leukemia mouse were treated with APS, Ara-c or APS + Ara-c respectively by peritoneal injection for 14 days, to explore the effect and mechanism of the chemicals on the mouse liver. Compared to the human leukemia NOD/SCID mouse model group with the treatments of APS, Ara-c and APS + Ara-c, We found that severe liver damage and pathological changes of the liver were able to alleviate: First, the number of white blood cells in the peripheral blood was significantly lower and with less transplanted K562 leukemia cells; Second, liver function damage was alleviated as liver function tests showed that alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBiL) were significantly reduced, while the albumin (Alb) was notably increased; Third, liver antioxidant ability was improved as the activities of the antioxidant enzymes glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) were significantly increased, and the contents of GSH and malonaldehyde (MDA) were decreased significantly in the liver; Fourth, the inflammation of the liver was relieved as the level of IL-1beta and IL-6, the inflammatory cytokines, were decreased significantly in the liver. Fifth, liver index was increased as the pathological observation showed that leukemia cells with diffused infiltration into the liver lobules were significantly reduced and with a remarkable increase of apoptotic positive cell rate by TUNEL test. Furthermore, the APS + Ara-c combined administration showed an even more significant positive effect. In conclusion, the APS, Ara-c therapy reduced the accumulation of leukemia cells within the liver, reduced the liver function damage and levels of inflammatory factors, improved antioxidant capacity of the liver tissue and thus alleviate the pathological changes of the liver. Moreover, the APS + Ara-c combination therapy may have an additive effect.

The aim of study was to investigate the pharmacokinetics and distribution of antithymocyte globulin (ATG) in recipients of partially HLA-matched hematopoietic stem cell transplantation. Fifteen patients with hematological disorders were received hematopoietic stem cell transplantation from partially HLA-matched related donor between October 2003 and October 2004 in the Institute of Hematology and People Hospital, Peking University. All patients including 5 cases of AML, 6 cases of CML, 3 cases of ALL, 1 case of AA were consecutively enrolled in the present study after providing written informed consent. Antithymocyte globulin was administered before allogeneic hematopoietic stem cell transplantation at a dose of 2.5 mg/kg daily for 4 consecutive days (total dose of 10 mg/kg) in the conditioning regimen. The concentration of rabbit ATG in the serum of 15 patients was measured using a new enzyme-linked immunoabsorbent assay (ELISA) for the Fc portion of rabbit IgG. The results showed that the washout phase of ATG elimination was analyzed over 0 - 120 days, results were well-fitted by a single exponential decay giving a mean elimination half-life (t(1/2) beta) of 29.67 +/- 2.60 days. A mean value for the apparent volume of distribution of ATG (V) obtained by analysis of data was 0.12 +/- 0.02 L/kg body weight. The serum concentration of ATG increased up to 44.8% at 5 day before transplantation, peak concentration of ATG was 136.0 +/- 10.3 mg/L, its concentration slowly descend at 0 day, fall up to 7.1 +/- 0.06 microg/ml at 90 day after dosing; t(max) 4.8 +/- 0.7 days; According to AIC (Akaike's information criterion), two compartment model of ATG was estimated. It is concluded that the conditioning regimen containing the dosage of 10 mg/kg of ATG is effective and safely in recipients of partially HLA-matched hematopoietic stem cell transplantation. There is no racial difference in the pharmacokinetics of ATG.

This study was aimed to investigate the effect of CD44 gene silence on the drug resistance and biologic activity of human multidrug resistant leukemia cell line K562/A02. The oligonucleotides of CD44 gene were designed according to related data of GenBank, double-stranded DNA was produced by annealing, and was inserted into pGCsilencerU6/Neo/GFP vector. The resultant recombinant plasmid pGCsiRNA-CD44 was transfected into K562/A02 cell line. Expressions of CD44, mdr-1 and blc-2 mRNA were assayed by real time RT-PCR. The 50% inhibitory concentration (IC50) of doxorubicin (ADM) for K562/A02 cell line was determined by MTT method. Cell cycle was determined by flow cytometry. The morphology of apoptotic cells was examined by Hochst 33258 staining. The results indicated that the siRNA eukaryotic plasmid directing at CD44 gene could effectively silence the CD44 gene of K562/A02 cells; as compared with control group, the CD44 expression in K562/A02 cells transfected with 4 pGCsiRNA-CD44 plasmids was obviously inhibited, while the inhibition of CD44 expression in cells transfected with siCD44-1 was strongest. After being transfected with pGCsiRNA-CD44, the expression of CD44 mRNA in K562/A02 cells reduced by 64.1% (p<0.05), at the same time the expression of mdr-1 and bcl-2 mRNA in pGCsiRNA-CD44-transfected K562/A02 cells reduced by 25.6% and 50.8% respectively. IC50 of K562/A02 cells after transfection decreased to (8.77+/-1.63) microg/ml and was obviously lower than that of control (17.97+/-1.61) microg/ml (p<0.01). After transfection for 48 hours, the ratio of K562/A02 cells in G0/G1 increased by 10.7%, and the cells displayed karyopyknosis, nuclear margination and apoptotic bodies. It is concluded that the siRNA plasmid specifically targeting CD44 gene can remarkably down-regulate the expression of CD44 gene, inhibit K562/A02 cell proliferation, induce its apoptosis and effectively reverse the multidrug resistance of K562/A02 cells.
