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.

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.

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.

OBJECTIVETo evaluate the efficacy and safety of high-dose dexamethasone-based regiments in newly diagnosed multiple myeloma patients with renal impairment.

METHODSThe clinical data of 22 patients with newly diagnosed multiple myeloma patients with renal impairment who received high-dose dexamethasone-based regiments from August 2006 to August 2008 in Peking Union Medical College Hospital were retrospectively reviewed.

RESULTSAfter receiving a median 4 cycles of high-dose dexamethasone-based regiments, renal impairment was reversed in 7 patients (31.8%) with a median time to reversal of 31 days. Sixteen patients (72.7%) achieved overall response, including 7 patients (31.8%) had complete remission / near complete remission. The grade 3 or 4 adverse events included neutropenia (13.6%), infections (22.7%), peripheral neuropathy (9.1%), and ileus (4.5%).

CONCLUSIONThe high-dose dexamethasone-based regiments are safe and effective for newly diagnosed multiple myeloma patients with renal impairment.
