0.05). Conclusion There is abnormal thyroid function in patients with anorexia nervosa. Most of the patients with anorexia nervosa are individuals with low T3 syndrome, rather than hypothyroid. Since this syndrome is reversible, thyroxine is not necessary during the treatment.

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.

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.

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. Its protective mechanism may be correlated with the inhibition of the oxidative stress injury.

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.

OBJECTIVETo evaluate the detection of cytomegalovirus (CMV) by polymerase chain reaction (PCR) for predicting the development of CMV disease.

METHODSOne hundred and thirty one allo-HSCT patients performed in the past 2 years were analyzed retrospectively. PCR-CMV was used to monitor CMV viremia and vireuria once a week after transplantation.

RESULTSIn the dynamic detection, CMV viremia was positive for at least one chance in 89 patients, vireuria did in 99 patients. Thirty-seven patients developed CMV disease with an accumulative incidence of 32.5%. The incidence of CMV disease was 15.6% in plasma CMV-PCR negative group, 31.3% in positive once group, and 47.3% in positive over twice group. There was significant difference among the three groups (P = 0.0126). The incidence of CMV disease was 24.8% in urine CMV-PCR negative group, 43.5% in positive once group, and 33.0% in positive over twice group, being no significant difference among them (P = 0.845). On analysis, viremia could predict the development of CMV disease: the PPV (positive predictive value) is 40.5%, NPV (negative predictive value) is 84.4%, sensitivity is 75.0%, and specificity is 69.2%.

CONCLUSIONSDetected by CMV-PCR, MCV viremia may predict the development of CMV disease, but MCV vireuria cannot.

OBJECTIVEAllogeneic marrow transplantation is a curative therapy for thalassemia, but no more than 30% of patients have HLA-indentical sibling marrow donor. The selection of alternative donors of unrelative marrow and the study on the probability of treating thalassemia major with unrelated donor bone marrow transplantation are of importance.

METHODSNine children with thalassemia were included in the study, and their gene mutational type were homozygote of thalassemia and double heterozygote, respectively. All of them were finally diagnosed of thalassemia major, and treated with unrelated donor bone marrow transplantation. To high-resolution HLA typing, two patients were matched, five had one unmatched isoform and two had two unmatched isoforms. The erythrocyte blood type was not matched in six patients. The preparative regimen included busulfan (oral use, 16 mg/kg, divided for 4 days), cyclophosphamide (intravenous use, 200 mg/kg, divided for 4 days), antithymocyte immunoglobulin (intravenous use, 30 mg/kg, divided for 3 days), and fludarabine (intravenous use, 125 mg/m(2), divided for 3 days). Ciclosporin A and methotrexate were used for graft-versus-host disease (GVHD) prophylaxis.

RESULTSAll patients had allergen reactions. One had hypotension. Five patients experienced I degrees approximately III degrees acute GVHD in the skin, while one had II degrees acute GVHD in liver. One patient had III degrees GVHD of intestines and gradually developed chronic GVHD in the skin, lungs and brain. One patient died of pulmonary hemorrhage. The duration when peripheral blood neutrophil count exceeded 0.5 x 10(9)/L was 12 - 26 days. The recovery time of WBC was as long as 23 - 110 days. Thrombocytes exceeded 50 x 10(9) within 61 approximately 142 days. The time when hemoglobin reached 100 g/L varied from 23 to 116 days. The last blood transfusion was on 13 - 62 days. Eight patients were fully grafted, while one was not grafted. During the 6 - 24 months of follow-up, seven patients' genotype of thalassemia major became normal. The erythrocyte blood type of five patients also changed into the same as that of donor. The hemoglobin was kept over 110 g/L without blood transfusion.

CONCLUSIONThe transplantation of unrelated donor bone marrow for thalassemia major was successful. Unrelated donor bone marrow transplantation could cure thalassemia major, which expanded the marrow donor source for the transplantation of thalassemia major.
