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 stress distribution and displacement by different distract directioos on mandibular corpus with finite element method. Methods:A three-dimensional finite element model of mandibular distraction osteogenesis was established.Von Mises stress as well as the displac ement of gnathion and gonion under different loads were measured. Result s:The stress and displacement were positively related with distract forc e. Von Mises stress primarily accumulated in distracted areas and were higher un der bilateral distraction parallel to the occlusial plane. Gnathion and gonion w ere positively displaced on X and Z axes and negatively displaced on Y axis. Distraction parallel to the mandibular body induced positive displaceme nt of mandible on X and Y axes and negative on Z axis. Concl usion:Transversal displacement to the opposite side is greater during un ilateral distraction, while displacement on the saggittal plane is greater durin g bilateral distraction.

Objective Finding characteristic of senile colon diverticula in 70 cases senile colon diverticula diagnosed by colonoscope through comparing and summarizing. Methods From Jan 1997 to Dec 2001, 70 cases older than 60 years old senile colon diverticula diagnosed by colonoscope in endoscopy department of PLA general hospital. Male 54 cases ,female 16 cases .Age from 60 to 84 years old, average age 68.70?5.39. Results ①With age increased, detectable rate of colon diverticula and multiple colon diverticula rised; ②Detectable rate in male higher than female; ③Whether the single or multiple diverticula ,all predilection site is in the right colon, rate of the right to the left is 2.8∶1(42∶15), and the single diverticula is more obvious. Conclusions ①Occurrence of diverticula have relation to age; ②Incidence in the right colon of senile is lower than of young people; ③The left colon diverticula and bilateral colon diverticula in senile is higher than in young people.

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 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.
