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.

In this paper, a model of three allogeneic mixed bone marrow transplantation of mice (BALB/c, H-2(d); C57BL/6, H-2(b); and CBA/N, H-2(k)) was established and whether or not prolongation of the survival time in recipient mice was observed. Lethally irradiated mice were transplanted with a mixture of a syngeneic plus two allogeneic bone marrow (A + B + C-->A, in a ratio of 1:4:4). At same time, mixed lymphocyte culture (MLC) with three allogeneic lymphocytes in vitro and two allogeneic antigens stimulated delayed type hypersensitivity (DTH) in vivo were performed. The results showed that the mice receiving mixed bone marrow transplant survived 56.6 +/- 27 days and the longest 103 days, however, only 15 +/- 5 days in the single allogeneic transplantation group. Whether two reacting cells to one stimulating cells or one reacting cells to two stimulating cells, all showed lower activity of MLC than that in one to one control group. In DTH assay, the mice sensitized with two allogeneic antigens showed lower reactivity than that in one antigen stimulated mice. It was concluded that the survival time of recipient mice was significantly prolonged after transplantation with three mixed allogeneic bone marrow.

The growth curve of single cell organisms in batch cultivation could divide into 6 phases, lag phase, acceleration phase, log phase, deceleration phase, stationary phase, and death phase, based on specific growth rate during cultivation process. There were significantly differences between deceleration phase and the other phases in cell growth, substrate consumption, product formation, and genes express profile. The deceleration phase was highly important to fermentation process. However, cognizing and teaching to the deceleration phase had been considerably weakened since a long period. So it should be strengthened.

Objective To assess the changes on the whole night polysomnography (PSG) in patients with chronic fatigue syndrome(CFS). Methods The whole night PSGs were recorded from 24 patients with CFS and 33 normal subjects. Results Compared with normal subjects, patients with CFS showed significantly reduced total sleep duration ([488.7?21.7]min vs [515.9?31.7]min, P

Objective To investigate the effect of vertebral artery (VA) dominance on basilar artery (BA) curvature and pontine or cerebellar infarct occurring around the vertebrobasilar junction of VA. Methods Radiological data (infarct laterality,VA dominance,BA curvature and their directional relationships) were analyzed in 91 patients with acute unilateral pontine or posterior inferior cerebellar artery (PICA) territory infarcts.Multiple regression analysis was performed to predict the moderate to severe BA curvature. Results The dominant VA frequently happened on the left side.Most patients had an opposite directional relationship between the dominant VA and BA curvature. Pontine infarct frequently happened opposite to the side of BA curvature and PICA infarct on the same side as the non-dominant VA side.The VA diameter was the only independent predictor for moderate to severe BA curvature (OR: 2.70; 95％CI: 1.22-5.98). Conclusion VA dominance is an important predictive factor of BA curvature,and BA curvature is usually opposite to the side of BA curvature; VA dominance and BA curvature caused by VA dominance increase the incidence of vertebrobasilar junctional infarcts.

OBJECTIVETo compare changes of hypothalamus-pituitary-adrenal axis (HPAA) in different rat models of Gan stagnation (GS), Pi deficiency (PD), Gan stagnation Pi deficiency (GSPD) syndromes, and to observe interventional effect of Chaishu Sijun Decoction (CSD, capable of soothing Gan-qi invigorating Pi) on them.

METHODSSeventy Wistar rats were divided into the normal control group (group 1), the GS group (group 2), the PD group (group 3), the GSPD group (group 4), the GS intervention group (group 5), the PD intervention group (group 6), and the GSPD intervention group (group 7) according to random digit table, 10 in each group. Rats in group 1 received no treatment. Rats in group 2 and 5 were modeled by chronic restraint method. Rats in group 3 and 6 were modeled by excess fatigue plus alimentary abstinence method. Rats in group 4 and 7 were modeled by chronic restraint, excess fatigue, and alimentary abstinence method. At the 2nd weekend of modeling, CSD at 2.86 g/kg was fed to rats in group 5, 6, and 7 by gastrogavage for 2 successive weeks. Equal volume of distilled water was given to rats in the rest 4 groups. On the 29th day, rats were killed, adrenal weight weighed, and adrenal index calculated. Levels of plasma and hypothalamus corticotropin-releasing hormone (CRH), plasma and pituitary adrenocorticotrophic hormone (ACTH), and plasma corticosterone (CORT) were determined using radioimmunity.

RESULTSCompared with group 1, adrenal index significantly decreased in group 2, 3, and 4 (P < 0.05). Of them, plasma and hypothalamus CRH, plasma CORT increased significantly in group 2 and 4 (P < 0.05). Besides, plasma and pituitary ACTH increased in group 4 (P < 0.05). Plasma and pituitary ACTH, as well as plasma CORT decreased significantly in group 3 (P < 0.05). Compared with group 2, 3, and 4, adrenal index increased significantly in group 5, 6, and 7 (P < 0.05). Compared with group 2, plasma CORT, hypothalamus CRH, and pituitary ACTH decreased significantly in group 5 (P < 0.05). Compared with group 3, plasma ACTH and CORT increased significantly in group 6 (P < 0.05). Compared with group 4, plasma CRH, ACTH, CORT, hypothalamus CRH, and pituitary ACTH decreased in group 7 (P < 0.05).

CONCLUSIONSThe function of HPA .axis was damaged to varying degrees in rats of the three models in this experiment. Hyperactivity of HPA axis existed in GS syndrome and GSPD syndrome. Impairment of feedback regulation in hypothalamus and pituitary was accompanied in GSPD syndrome. Hypofunction of HPA axis existed in PDS. CSD, capable of soothing Gan-qi invigorating'Pi, showed improvement on disarranged HPAA, but with optimal effect on GSPD syndrome. CSD had higher correlation with GSPD syndrome.

BACKGROUNDRituximab is used extensively in combination with chemotherapy to cure non-Hodgkin's lymphoma (NHL), and not only accelerates short-term improvement, but also prolongs patient survival and decreases receptor relapse. The aim of this study was to evaluate the impact of Fcgamma IIIA (FcgammaRIIIA) gene polymorphisms on the response to rituximab therapy for newly diagnosed B-cell lymphomas.

METHODSPatients with newly diagnosed histologically-proven CD20-positive B-cell lymphoma were eligible for the study. All of the patients received rituximab combined with chemotherapy (CHOP). The FcgammaRIIIA type was analyzed by PCR. The initial efficacy was assessed after 6 cycles and the long-term survival was determined.

RESULTSThirty-four patients were recruited between October 2005 and April 2006. The FcgammaRIIIA distribution was as follows: 11 patients were VV, 5 were FF, and 18 were VF. After a median of 6 cycles (range 4-8) of rituximab combined chemotherapy, the overall response rate was 79% (82% in the VV group, 83% in the VF group, and 60% in the FF group; P=0.04). After a median follow-up time of 37 months (range 34-41), there were 12 relapses among 27 responders (44%); 5 of 9 patients (5/9) in the VV group, 5 of 15 patients (33%) in the VF group, and 2 of 3 patients (2/3) in the FF group (P=0.21). The 1-year overall survival in the VV, FF, and VF groups was 80%, 60%, and 80%, respectively, and the 3-year overall survival was 58%, 40%, and 69%, respectively (P=0.08). After analysis by COX regression, only the international prognosis index and response to initial treatment were significantly related to overall survival.

CONCLUSIONSThe distribution of FcgammaRIIIA polymorphisms in this B-cell lymphoma population shows that VF is most frequently expressed, followed by VV and FF. Patients with the FcgammaRIIIA VV and VF types are more sensitive to the initial treatment of rituximab combined with chemotherapy and have superior long-term survival compared with those with FF. Nevertheless, FcgammaRIIIA polymorphisms do not predict prognosis independently.

OBJECTIVETo evaluate the efficacy and safety of autologous peripheral blood stem cell transplantation (auto-PBSCT) after high dose melphalan in patients with POEMS syndrome.

METHODSNine patients including 6 males and 3 females received 10 auto-PBSCT after high dose melphalan in our hospital from June 2005 to October 2009. The median age at transplantation was 44 (39 - 48) years. The median time from onset of disease to transplantation was 12 (5 - 60) months. Peripheral stem cells were mobilized by G-CSF alone in one patient and 8 patients by G-CSF plus chemotherapy. Two patients were conditioned by melphalan 140 mg/m(2) and 7 by melphalan 200 mg/m(2). The median number of MNC was 3.75 (1.05 - 8.33) × 10(8)/kg, and that of CD34(+) cell was 5.37 (1.32 - 10.90) × 10(6)/kg.

RESULTOne patient received tandem auto-PBSCT and others received single one. Stem cell engrafted in all but 1 patient who died of severe infection and acute renal failure on day 9 after transplantation. Eight patients were evaluable for response. The median time to ANC ≥ 0.5 × 10(9)/L and platelet ≥ 20 × 10(9)/L was 10 (9 - 11) and 11.5 (9 - 14) days respectively. Two patient reached negative immunofixation electrophoresis (IFE) after stem cell mobilization and transplantation respectively, and the other 6 remained IFE postive after auto-PBSCT. Skin changes and edema of lower extremities were improved in 5 of 6 patients, lymphadenopathy relieved in 1 and papilledema improved in 2 of 3 patients. All but 1 patient achieved gradual neurologic improvement after transplantation.

CONCLUSIONPBSCT is an effective and safe therapy for POEMS syndrome patients with low treatment related mortality.
