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 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 study effect of octreotide combined with ulinastatin on serum lipase, CRP and clinical efficacy in patients with acute pancreatitis.Methods 60 cases with acute pancreatitis were selected and divided into 2 groups.30 cases in the control group were treated with ulinastatin.30 cases in the experiment group were treated on the base of the control group by octreotide.Clinical effects, lipase and CRP were compared after 1 weeks treatment.Results Compared with the control group after treatment, the serum lipase, CRP level was lower in the experiment group (P<0.05), and the clinical total effective rate was significantly higher in the experiment group than in the control group ( P<0.05 ) . Conclusion Octreotide combined with ulinastatin has good clinical curative effect on acute pancreatitis.It is speculated that the mechanism may be related to the decreasing of serum lipase and CRP level in patients.

Objective To analyze the pressure source and effect of comprehensive intervention in type 2 diabetes mellitus patients. Methods 200 diabetes patients were randomized into the observation group and the control group with 100 cases in each group. Comprehensive intervention was introduced into the observation group and the control group underwent routine treatment. The pressure source was investigated after intervention by questionnaires and the results were compared. Results Fearing of serious complications bocame the most common cause of pressure. The scores of Self-rating Depression Scale(SDS)and Self-rating Anxiety Scale(SAS)were lower and the biochemical index was also better in the observation group than those in the control group as well as those before intervention in the observation group(P＜0.05).Conclusion The depression, anxiety status and biochemical index in patients with type 2 diabetes mellitus were effectively controled by corresponding and comprehensive intervention measures according to the sequence order of pressure source.

Objective To preparing the reference material(RM) of lactate dehydrogenase(LD),we purification of LD from human erythrocyte(RBC)and studied its properties.Methods Using a modified procedure which including complete hemolysis of the RBC,hydroxyapatite treatment,(NH4)2 SO 4 Precipitation,CM- Sephadex C 50,Sephadex G100 and 5'- AMP- Sepharose 4B affinity chromatography.Results The purified LD has a sepecific activity of 163.0 kU/g protein.It is almost free of contaminating enzymes.Two corresponding bands were observed on both PAG plates stained for either protein or LD activity after electrophresis had been done.The apparent Michaelis constants were of 1.000 and 0.179 mmol/L for L-lactate and NAD and of 0.119 mmol/L 0.062 mmol/L for pyruvate and NADH respectively.Conclusion The final purified LD was found to be very similar to that in human serum in catalytic properties.It is intended to be a fundament to prepare a RM for the measurement of LD.

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 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

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.
