Angiogenesis is an important link of tumor growth, invasion and metastasis. The tumor angiogenesis targeting strategy for the treatment of cancer has become a hot spot in oncology research currently. Signal transduction of tumor angiogenesis is a complex, multi-factor, multi-way and cross network system. Treatment for a single target is often not sufficient to halt or reverse its highly heterogeneous structure and abnormal shape. Therefore, it will be an important research direction that the combination of different pathways and mechanisms of medications effect on signaling pathway in tumor angiogenesis by multi-target. A number of experimental studies found that qi-reinforcing and blood-activating medication can play a regulating role of multiple targets, multiple pathways in tumor angiogenesis. It had different effect on tumor angiogenesis against tumor invasion and metastasis.Qi-reinforcing and blood-activating medication will have broad prospects in the treatment of tumor and angiogenesis.

Objectives:To explore the possibility of using experimental animal models as a new means for studying the pathogenesis and symptomatologic development of radiation-induced lung injury,and provide theoretical and experimental evidences for early prevention and treatment with the traditional Chinese medicine.Methods:80 female Wistar rats were divided randomly into the model group and control group with 40 rats in each group respectively.The rats in model group were anesthetized and fixed,and a 2cm?3cm area of the right lungs received 6mV X-ray radiation at 3Gy?2/w and a maximal 10/5w.Eight rats randomly selected from each group were sacrificed at the end of weeks of 3,5,8,12 and 26.Diagnostic techniques of TCM were employed to analyze symptomatological and developmental characteristics of TCM in radiation-induced lung injury during exposure by dynamic examination and comparison of living rats,gross lung samples and tissue sections.Results: Signs and symptoms including redness around nose and eyes,yellowish secretion,tachypnea,dry stool,lethargy,sluggishness, inactiveness were observed in model group in early stage of radiation exposure,which consistent with dominant heat in the interior and primordial qi exhaustion syndrome.Swollen lungs,bright redness on surface and red bleeding patches were observed in early stage of radiation;microscopic examination showed interstitial tissues,and readily visible congestion,hemorrhage and edema of pulmonary interstitial tissues,consistent with damaged blood collaterals by heat and blood escaping circulation syndrome.In the later stage of radiation exposure,the lungs showed dark appearance,apparent purple petechia,hard texture and poor elasticity.Microscopic examination showed remote hemorrhage foci,pulmonary capillary stasis or closure,and focal fibrotic clumps,consistent with obstruction of collaterals by blood stasis syndrome.No abnormal changes were observed in the control group.Conclusions:Animal experiments can redeem the clinical inadequacy of traditional inspection,auscultation and olfaction,interrogation and feeling pulse and palpation diagnostic techniques,modern pathological methods can be utilized to study symptomatology of traditional Chinese medicine.Symptomatological and developmental characteristics of'heat toxin impairment in radiation-induced lung injury characterized by heat damaging pulmonary collateral syndrome in early stage and pulmonary collateral stagnation syndrome in the advanced stage'can be revealed at living organism,gross lung sample and microscopic pulmonary tissue levels,thus providing theoretical basis for early prevention and treatment of radiation-induced lung injury using'cooling blood to remove apthogenic heat'.

Objective To investigate the levels of serum interleukin(IL)-18 in patients with chronic renal failure (CRF)and its relationship with relevant indexes. Methods Sixty patients with CRF were divided into three groups: patients with CRF (CRF group, n = 18) ,patients with bemedialysis (HD group, n = 22) and patients with peritoneal dialysis (PD group,n = 20). 20 healthy subjects were taken as controls. The levels of serum IL-18, tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hs-CRP) were detected by means of ELISA. Serum albumin (ALB) ,total cholesterol (TC) ,triglyceride (TG) and serum creatinine (SCr) levels were detected by con-ventional means. The GFR was measured by using the abbreviated Modification of Diet in Renal Disease study (MDRD) equation. Differences in continuous variables between the three groups were evaluated. Results The lev-els of serum IL-18 were significantly increased in CRF[(497.7 ± 120.7) ng/L], HD[(538.1 ± 113.2) ng/L] and PD[(565.7 ± 122.1) ng/L] patients than those in healthy subjects[(163.9±42.2) ng/L] (P <0.01). Further-more,serum IL-18 levels in HD patients were higher than these in CRF patients (P <0.05). Serum IL-18 levels in CRF were positively related to serum TNF-α,hs-CRP and SCr(r =0. 636,0.436,0.367,P <0.01) ,and negatively related to GFR(r = -0.515 ,P <0.05). Conclusion The levels of serum IL-18 are markedly increased in patients with CRF,HD and PD,and related to the levels of TNF-α,hs-CRP and GFR,so IL-18 might be an important marker of sub-clinical inflammation in patients with chronic renal failure.

Objective To explore the effects of mouse nerve growth factor (mNGF) on expression of metallothionein I/II (MT I/II) and cytochrome C (Cyt C) in hippocampus of pentylenetetrazol (PTZ)-induced epileptic (EP) young rats. Methods Fif-ty SD rats aged 19 days were randomly divided into control group, EP group, mNGF low, medium, and high dose groups. Each group had 10 rats. Control group was injected with normal saline every day, and EP group was intraperitoneally injected with PTZ 40 mg/(kg·d) for 21 days in succession. The mNGF low, medium, and high dose groups were respectively intramuscularly injected with mNGF 500, 1 000, 2 000 AU/(kg·d) for 7 days in succession after PTZ injection. Changes of body weight, behav-ioral performance were recorded. The positive cells of MT I/II, Cyt C were examined by immunohistochemisty. The levels of MT I, Cyt C mRNA in hippocampus were measured by real-time PCR. Results The number of MT I/II, Cyt C positive cells and the levels of MT I, Cyt C mRNA in hippocampus had signiifcant differences among groups (F=15.98-105.76, P=0.000). The number of MT I/II, Cyt C positive cells and the levels of MT I, Cyt C mRNA of EP group were higher than those in control group, mNGF low, medium, and high dose groups (P<0.05). The number of MT I/II, Cyt C positive cells of mNGF low group were higher than those in mNGF high dose group (P<0.05). The levels of MT I, Cyt C mRNA of mNGF low group were higher than those in mNGF medium and high dose groups (P<0.05). The number of MT I/II, Cyt C positive cells and the levels of MT I, Cyt C mRNA had no differences between mNGF medium and high dose groups (P>0.05). Conclusions As a stress protein, metallothionein is involved in the process of chronic epilepsy along with Cyt C. mNGF has neuroprotective effects on the hippocampus of epileptic rats in dose dependent manner.

AIM: To study the effects of [8-(diethylamino) octyl-3, 4, 5 -trimethoxybenzoate] (TMB-8), an intracellular Ca2+ antagonist, on the activation, proliferation and cell-cycle distribution of the mouse T lymphocytes stimulated by concanvalin A (Con A) in vitro. METHODS: After stimulated with Con A, T cells were treated with different concentrations of TMB-8 alone and its combination with cyclosporine A (CsA). The expression of CD69, the early marker of CD3+ T cell activation, was measured by FACS. The proliferation-related index was determined by carboxyl fluorescin diacetate succinmidyl ester (CFDA-SE) flow cytometry. The cell-cycle distribution was analyzed by propidium iodide staining.RESULTS: After 6 h culture, the activation rate of CD69+ T cell in Con A group was (74.88?1.88)%. 10, 20 and 40 ?mol/L of TMB-8 inhibited the expression of CD69 (P

BACKGROUND: People have concerned with the effect of fibroblast growth factor biological protein sponge on the repairing effect of traumatic ulcer.OBJECTIVE: To observe the repairing effect of fibroblast growth factor biological protein sponge on the repairing effect of traumatic ulcer and its possible adverse reactionDESIGN: Grouping comparison observation.SETTING: Staff Room of Physiology, Medical College of Jinan University PARTICIPANTS: Totally 40 cases of traumatic ulcer accepted the treatment in the First Hospital of Jinan Univerity between March 2004 and May 2005 were recruited. Patients with diabetes mellitus and infection on the whole body were excluded. Traumatic ulcer lay in the shank. Patients were randomly divided into experimental group and control group with 20 in each group.INTERVENTIONS: In the experimental group (n=20), sterilized fibroblast growth factor biological protein sponge was used and in the control group (n=20), sterilized petrolatum gauze dressing was used on the wound.Change the gauze dressing once per day until the wound healed. Drugs,which affected wound growth, were not used on the whole body and at the local part. Wound healing status was evaluated 1, 2 and 3 weeks after changing the drugs (The secretion of a wound was divided into: nothing, a little, middling, a great deal. frontier reaction of wound was divided into:nothing, slight, middling, severe.). Pigment deposition and scar was recorded after wound healing.MAIN OUTCOME MEASURES: Healing time of ulcer, healing course of the wound and adverse reaction of the patients in the two groupsRESULTS: Totally 40 patients of the two groups entered result analysis.Wound healing status after treatment of the patients in the two groups: The rate of wound healing in 3 weeks in the experimental group was significantly higher than that in the control group [95% (19/20),55% (11/20),χ2=8.533,P ＜ 0.05]. Wound secretion and peripheral inflammatory reaction of the wound in the experimental group was obviously milder than that of the control group; there was no obvious adverse reaction and scar of the wound found in the two groups.CONCLUSION:FGF biological protein sponge can promote the healing of traumatic ulcer; shorten the healing time without scar and adverse reaction.This dressing is convenient, safe, and non-irritative.
