Methods: The radioactive intensities of 3H leucine in brain protein and 3H uridine in RNA of brain tissue of young mice were observed by the methods of incorporation in vivo and group control observation.Results: The radioaetive intensity of 3H leucine of Yizhi Oral Solution group was higher than that of cycloheximide pathological model group ( P

In order to observe the febrifugal response of needling "Chang Qiang Point", and analyse its mechanism lumbar spinal cord of rabbits were damaged in the expermental study. The experimental findings were as follows: 1. It was found that cAMP content in csf was striking increased, when leukocytic pyrogen fever of rabbits was significant. During needling "Chang Qiang Point" of febrile rabbits, however, febrile response was markedly inhibited(at 60 min~?T℃ was 0.23?0.07 and TRI4 0.61?0.03). There was significant difference(P0.05). 3. After damaging lumbar spinal cord of rabbits, there were certain change of rectal temperature and the febrile response, but it had no effect on cAMP content in csf. The authors infered that the impulses from "Chang Qiang Point" transmiled Via spinal cord might be closely associated with reflex mechanism and the change of cAMP content might play an important role in the mechanism of febrifugal effect during needling "Chang Qiang Point" in febrile rabbits.

Objective　To study the clinico-pathological features of primary adrenal lymphoma (PAL).　Methods　2 cases of PAL were reviewed and studied.　Results　The age of the 2 patients was 45 and 57.The presenting symptoms were nonspecific.Histologically,the neoplasm was composed of numerous medium-sized cells with round nucleus,usually 1-2 in number and with relatively abundant basophilic cytoplasm.The neoplastic cells showed frequent mitosis.Immunohistochemically,the tumor cells were strongly positive for LCA,L26 and CD74 while negative for UCHL-1,S-100 protein and CK. One case was discharged 3 months after operation because of dyscrasia and the other was lost on follow up.Prognosis of PAL was poor.　Conclusions　PAL is extremely rare with a high grade of malignancy.The diagnosis could be made on histopathological studies and immunohistochemical studies.

Objective To study the expression and cellular localization of STAT3 and SOCS-3 in the motor neurons of normal rat spinal cord. Methods Immunocytochemistry and morphometry methods were used in the present study. Results STAT3 immunocytochemical staining was mainly distributed in the cytoplasm of the motor neurons of the ventral horns, SOCS-3 immunoreactive products were extensively distributed in the neurons of the ventral and dorsal horns, glia and fibers of the spinal cord. In the ventral horn, SOCS-3 immunoreactivity was found in the nuclei and/or cytoplasm of the motor neurons.Conclusions STAT3 and SOCS-3 are extensively distributed in the normal adult rat spinal cord and SOCS-3 is existence in the forms of nuclear or cytoplasmic protein.

Objective To evaluate the therapeutic effects of combining acupuncture and physical therapy with drugs on treating Duchenne muscular dystrophy (DMD).Methods Sixty infants with DMD were randomly divided into a treatment group and a control group (n =30 in each).Both groups were injected with Bozhi glycopeptide and given levocamitine and fructose sodium diphosphate orally.Moreover,the treatment group was additionally given acupuncture and physical therapy.Before and after 90 days of treatment,the time to walk 10 metres and to climb stairs of 2 metres high was measured,as were the serum creatine phosphate kinase (CPK),lactate dehydrogenase (LDH) and aspertate aminotransferase (AST) levels of all participants.Results After treatment,the average walking and stair climbing times of both groups were significantly shorter,and those of the treatment group were significantly shorter than those of the control group.Moreover,the average CPK,LDH and AST levels in the treatment group were significantly lower than before treatment and than those of the control group after treatment.There was a significant difference in the overall response rates,with 93％ observed in the treatment group and 73％ in the control group.Conclusion Combining acupuncture and physical therapy with drugs can significantly increase the mobility and improve the serum CPK,LDH and AST levels of children with DMD.

Objective To explore the role of ripply1 in zebrafish dorsal-ventral development .Methods Using ze-brafish whole-mount in situ hybridization to examine the ripply1 expression pattern in early embryo development .To analyse the expression pattern changes of dorsal-ventral marker genes at shield stage and the morphological changes at 24 hpf (hours post-fertilization) after overexpression of ripply1 by injecting synthetic mRNA at 1-cell stage.Using Tol2 transposon technology to obtain a ripply1 promoter driven GFP transgenic fish and to identify promoter region that recapitulates endoge -nous ripply1 expression pattern .Results The in situ hybridization results revealed that ripply1 specifically expresses in the future dorsal region at shield stage .Overexpression of ripply1 caused an enhanced expression of dorsal marker genes and a reduction of ventral marker genes .Embryos overexpressing ripply1 also showed severely dorsalized phenotype , with enlarged head, reduced ventral yolk extension , and shortened posterior trunk and tail regions , and the formation of a secondary trunk axis.Transgenic fish revealed the maternal expression of ripply1 and suggested that a 1.2 kb promoter-driven GFP is able to recapitulate the endogenous gene expression pattern .Conclusion ripply1 may participate in the early development of dor-sal-ventral axis in zebrafish embryo .

Objective To investigate the efficacy of losartan on the improvement of heart function and its effect on uric acid in patients with chronic heart failure (CHF). Methods Eighty-five patients with CHF were divided into two groups randomly. Routine anti-CHF treatment included cardiotonic, diuresis, isosorbide dinitrate, beta-blockers. In losartan group(n=43), patients were given routine anti-CHF treatment and losartan. The patients in control group(n=42) were treated by routine anti-CHF treatment and Benazapril. The heart functional was evaluated. The content of serum uric acid, electrocardiogram, and Duppler ultransonography were measured before and after treatment respectively. Results The variance of heart function, left ventricle diastoic diameter (LVDD), left ventricle ejection fraction (LVEF) and cardiothotic ratio did not show statistical difference. However, they were improved sharply as compared with base-line condition in both groups after 3 months and 12 months treatment(P

The occurrence and development of solid tumor is a multi-factor,multi-step and multi-gene interactive process.The generation of micro vasculature of solid tumor,as well as the interaction between tumor and micro-environment,decides the tumor's biological characteristics of growth,recurrence,invasion and metastasis.Reasonable application of anti-angiogenesis therapy enables the normalization of tumor vascular system to enhance the efficiency of chemotherapy and radiation treatment and prolong survival time in patients.

OBJECTIVE: To observe the influence of safflower yellow (SY) on inflammatory injury in cortex of APP/PS1 double Alzheimer's disease (AD) transgenic mice. METHODS: Six-month-old APP/PS1 transgenic male mice were used in the study. The mice were randomly divided into five groups: model group, galanthamine group, high, middle and low dose groups of Safflower Yellow, and wild-type mice with same age were selected into normal control group. Each group mice were performed Morris water maze test after given different drugs by gavage for three months. The level of IL-1β, IL-4, IL-10, IFN-γ and iNOS in cortex were detected by ELISA. RESULTS: Compared with wild-type controls, the ability of learning and memory were decreased in the model group. The level of IL-1β, IFN-γ and iNOS increased as well as the expression of IL-4, IL-10 decreased (P<0.01). After SY treatment, the learning and memory abilities of middle dose group were elevated (P<0.01); it could obviously down-regulate the expression of IL-1β, IFN-7, iNOS and up-regulate the expression of IL-4 and IL-10 (P<0.01). High and low dose groups could obviously down-regulate the expression of IFN-γ, iNOS and up-regulate the expression of IL-10 (P<0.01). High dose group does had obvious effect of up-regulating the expression of IL-4 (P<0.01), Both of High and low dose groups didn't have statistical significance on the expression of IL-1β. CONCLUSION Safflower Yellow could improve the ability of learning and memory and exert protective effects on inflammation damage in the cortex of APP/PS1 transgenic mice.
