The concept of cause in TCM is different from the etiology concept in modern TCM. In modern TCM,the etiology is equal to pathogenic factors.At present,the significance of 'pathogenic factors'in TCM was affected by modern TCM,and this description can't show the essence of TCM theory and is not conducive to the development of cause theory of TCM.

Objective: To discuss the feasibility of immune tolerance in rat small bowel trans-plantation induced by immature dendritic cells isolated from SD and Wistar rat. Methods: Dendritic cells isolated from liver or bone marrow of inbred strain Wistar and SD rat were cultured for five to nine days. A week before operation, the recipient rats were injected 2?106 inmature DCs from vena dorsalis penis and observed. The models of heterotopic small bowel transplantation (SBT: SD→ Wistar)were established. Acute immuno- rejection levels were evaluated by HE. Results: Varying degrees of rejection were observed in 3, 5, 7 days after operation. Conclusion: Immature DC can induce allogenic immunological tolerance of rat small bowel transplantation.

Objective To investigate the therapeutic effect and mechanism of total flavone of haw-thorn leaf ( TFHL) on p38MAPK signaling pathway and inflammation factors in rats brain with chronic cere-bral ischemia.Methods SPF class healthy male SD rats were randomly divided into sham group, model group,TFHL group and Ginkgo leaf group( 12 rats in each group) .Permanent bilateral carotid artery ligation was used to prepare chronic cerebral ischemia model.Morris water maze method was used to evaluate learn-ing and memory abilities of rats.Immunohistochemistry and Western blot methods were used to measure the expression of caspase-3 and p38MAPK proteins.ELISA method was used to measure the amounts of TNF-αand IL-1βin hippocampal tissue.Results Compared with the model group,TFHL treatment (36 d) can im-prove learning and memory capabilities of vascular dementia rats,shorten the escape latency ( TFHL group(10.01±2.85) s vs Model group (19.54±6.12) s, P<0.05) and the course of searching platform(TFHL group(2.6044±0.3219)m vs model group(3.3502±0.6231)m, P<0.05),increase the numbers of crossing the platform (TFHL group(5.17±2.12) times vs Model group (3.96±1.34) time,s P<0.05) and the platform quadrant swimming distance percentage (TFHL group(48.22±7.39)%vs model group (33.42±5.32) %, P<0.01).The number of caspase-3 positive cells in the hippocampus significantly reduced (TFHL group(1.677 ±0.164) vs Model group (2.387±0.171), P<0.05),the expression level of P38MAPK protein (TFHL group (0.0161±0.0003) vs Model group (0.0254±0.0018), P<0.05),TNF-α(TFHL group(19.61±3.61) ng/10 mg vs Model group (27.82±6.57) ng/10 mg, P<0.01)and IL-1β(TFHL group(24.41±2.56) ng/10 mg vs Model group (29.43±5.26) ng/10 mg, P<0.05) were significantly decreased.Conclusion TFHL plays a protective role in nerve function of the chronic cerebral ischemia rats.The mechanism of its antia-poptosis might be associated with the activation of P 38MAPK signaling pathway,inflammation and the apoptosis of neurons in the brain.

Esthesioneuroblastoma is one of the most uncommon nasal malignancies which is characterized by low incidence and high misdiagnosis rate.The only prognosis factor is the metastasis on lymph node of neck.Its clinical symptoms are associated with tumor infiltrating extent.Pathological diagnosis is the “gold standard” on esthesioneuroblastoma,and the Kadish staging based on the image is the most important staging standard.The traditional operation therapy mode has been replaced by the combined method of operation and radiotherapy,with the adjunctive therapy of chemotherapy.

Objective To introduce a new design of interlocking system which is easy in use, makes the distal fracture fragments well aligned and rigidly fixated, reduces exposure to radiation for the surgeon and patient, and allows for a decrease in operating time. Methods The new interlocking system was designed to be a self-locking nail with bevels (b-SLN). According to the bevel principle, the axial force of the nail should be turned into a transverse force so as to control the transverse nail's movement. 10 dry-bone simples were made into the fracture model of the middle-femur to test the prototype nail. The retention of the nail in the intramedullary cavity was evaluated by the radiogram. The mechanical properties of a simulated model of single leg loading were tested on the instron-1342 type MTS. Results The prototype nail performed well as designed. The process was stable and reliable. The retention in the intramedullary cavity was fine. The shearing force between the transverse nail and main nail was enough to cut anything around them. The mechanical properties of b-SLN were similar to those of the Grosse-Kempf nail, better than auto fork compress locked intramedullary nail, and much better than MHUA nail and Ender's nail. Conclusions The structure of b-SLN is simple and reliable. There is no focus-point under stress. Its biomechanic properties are satisfactory. It is easy to use with no need of fluoroscopes in the operating theatre.
