Objective:To explore effects of Baoyuan Huoxue Granule on senile type 2 diabetes with Qi deficiency and blood stasis,and expression rates of membrane glucoprotein selectin P(CD62p)and fibrin receptor(PAC-1)in the granule of platelet.Methods:60 cases of senile type 2 diabetes with Qi-deficiency and blood stasis were randomly divided into two groups,a simple western medicine control group(n=30)and a test group(n=30)treated by routine western medicine and Baoyuan Huoxue Granule.The treatment was given 2 months.Their clinical therapeutic effects,and the expression rates of CD62p and PAC-1 before and after treatment were investigated.Results:In the test group,12 cases(40%)were markedly effective,15 cases(50%)effective,3 cases (10%)ineffective,with an effective rate of 90%;In the control group,3 cases(10%)were markedly effective,12(40%) effective,15(50%)ineffective.the effective rate being 50%,with significant difference between the two groups in total effective rate(P

280r/40min). So the PD model was regarded eligible. In the site of lesion in SN, the number and volume of dobaminergic neurons were decreased, and the tissue structure of SN became indistinct, the levels of dopamine (DA), dihydroxyphenylaceticacid (DOPAC), homovanillicacid (HVA) 5-hydroxytryptamine (5-HT) and 5-hydroxyindoleaceticacid (5-HIAA) were more conspicuously reduced than that in uninjured side. TH-immunoreactive cells of substantia nigra compact part were lessened obviously on injured side. The abnormal rotatory behavior of PD rats did not spontaneously disappear during 10 months of continuous observation. Conclusion The PD rat model, which is reproduced by injecting 6-OHDA to selectively destroy dopaminergic neurons in the substantia nigra of rat, is stable and reliable, and demonstrated similar primary pathological changes of PD.

Objective To explore the mechanism of therapeutic effect of Yichantang in the treatment of Parkinson′s disease (PD). Methods A rat model of PD was replicated. The experimental animals were divided into a normal control group,a normal saline control group and a Yichantang group. Changes in the rats' behavior pattern was obrerved. Using the technique of intracerebral dialysis,the content of catecholamine like substances in the nigral extracellular fluid(NECF)was measured by means of high performance liquid chromatography(HPLC). Changes in the affinity and quantity of M and DA receptors were determined too. Results Yichantang markedly improved the rats' rotation behavior,and enhanced the Bmax and KD of DA and M receptors in the brain tissues on the side of lesion. The levels of DOPAC,HVA,DA and 5-HT in the NECF of the side of lesion in the Yichantang group were significantly higher than that of the normal saline group ( P

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'.

BACKGROUND: Parkinson disease (PD) not only influences motor function, also affects sensation and cognition. Treatment with dopamine can only control symptom and has well side effect; however, yichan tang has great effect on treating PD in clinic.OBJECTIVE: To observe the effect of yichan tang on praxiological behavior, catecholamines substance in cerebral tissue and substantia nigra nerve cells of PD rats and analyze its effective mechanism.DESIGN: Randomized control animal study and single-blind evaluation.SETTING: Department of Traditional Chinese Medicine of General Hospital of Chinese PLA.MATERIALS: A total of 120 female SD rats weighing 180-200 g were selected in this study. Seventy modeling PD rats were randomly divided into saline group (n=30) and yichan tang group (n=40) according to digital table. Another 30 non-modeling rats were regarded as normal control group. Yichan tang was made of 15 g shanyurou, 15 g shichangpu, 10 g xianlingpi, 10 g roucongrong, 15 g gouqizi, 15 g danshen and 8 g wugong,etc., and provided by Dispensary of Chinese herb of General Hospital of Chinese PLA. Drug was decocted for 30 minutes to filter the solution and then concentrated into decoction including 1.0 g/mL raw materials.METHODS: The experiment was carried out at the Animal Laboratory of General Hospital of Chinese PLA from September to December 2001. PD rat model were established with 6-hydroxy-dopa to observe behavior of rats.The administration of rats (body mass/kg) in yichan tang group was 10 times as the administration of the adults (60 kg) (5 g/kg). Rats were perfused once a day and weighted once a week. The dosage of administration was regulated as the body mass changing, and the administration lasted for 8 weeks. Rats in saline group and normal control group were perfused with the same volume of saline as the criteria of body mass. Rotatory behaviors of rats in normal group, saline group (model group before administration)and yichan tang group were observed before administration and at 5, 6, 7 and 8 weeks after administration. Changes of content of catecholamines in extracellular fluid of cerebral tissue were measured with micro-dialysis technique and high performance liquid chromatography (HPLC), meanwhile, changes of substantia nigra nerve cells on both sides of corpus striatum were observed under 20-time and 40-time optic microscopes.MAIN OUTCOME MEASURES: Effect of yichan tang on medium of cranial nerve of PD rats; changes of substantia nigra nerve cells on both sides of corpus striatum with optic microscope and electron microscope; evaluation of yichan tang.RESULTS: Among 100 rats, 6 rats in yichan tang group died because of failure perfusion, 5 in saline group and 2 in normal control group. Therefore, 87 rats were involved in the final analysis. ① At 5, 6, 7 and 8 weeks after treatment, rotatory times within 40 minutes were all shorter in yichan tang group than those in saline group [(112.34±33.36), (91.16±73.06),(72.05±20.77), (61.63±17.93), (340.90±52.97) times, P ＜ 0.01]. ② Levels of 3,4-dihydroxybenzene acid, homovanilic acid, dopamine and 5-serotonin on the injured side were lower than those on the uninjured side (P ＜ 0.05-0.01). After treatment, levels of mediums mentioned above were higher in yichan tang group than those in saline group (P ＜ 0.05-0.01); however,there were no significant differences of mediums on the uninjured side in the three groups (P ＞ 0.05). ③ Pathological observation: Amount of substantia nigra nerve cells on the injured side was more in yichan tang group than that in saline group; moreover, volume of neurons was full, structure was clear, and values of Golgi complex and mitochondria were close to the normals.CONCLUSION: Yichan tang can relieve injured degrees of substantia nigra nerve cells, facilitate the repair, increase the content of endogenetic catecholamines in cerebral tissue, and improve rotatory behavior of PD rats.

Objective To explore the mechanism of Yichan decoction(抑颤汤) in treatment of Parkinson′s disease(PD).Methods A PD rat model was made by direct injection of 6-hydroxydopamine(6-OHDA) into the brain to destruct the compact part of substantia nigra(SNC).One hundred Sprague-Dawley(SD) rats were randomly divided into a normal control group,a PD model group and a Yichan decoction treatment group and they were treated for 8 weeks.The rats′ behavior pattern changes were observed before treatment and from 5th weeks after treatment.The changes in the dissociation constant(Kd) and maximum number of binding sites(Bmax) of dopamine(DA) receptors,and neurotensin-immunoreactive(NT-IR) in substantia nigra after treatment were determined by using the technique of radioimmunity.Results Yichan decoction could markedly improve the rotation of PD model rats and decrease the average number of rotation from(349.56?62.28) circle/40 minutes to(61.63?17.93) circle/40 minutes(P

Background: Radiation pneumonitis is one of the most common complications during radiotherapy of thoracic tumors. It impacts the quality of life of the patients and has life-threatening danger. However, there is a lack of drugs for prevention and treatment of this disease. Objective: To evaluate the efficacy of Liangxue Jiedu Huoxue Decoction, a compound traditional Chinese herbal medicine, in prevention of radiation pneumonitis. Design, setting, participants and interventions: A prospective randomized clinical study was conducted. A total of 100 patients diagnosed with lung cancer from Department of Radiotherapy, Chinese PLA General Hospital, who were planning to receive radiotherapy, were randomly assigned into treatment group and control group, with 50 patients in each group. In the treatment group 3 cases were lost to follow-up and one case was excluded, while in the control group 6 cases were lost to follow-up and 2 cases were excluded. Patients in the treatment group were treated with Liangxue Jiedu Huoxue Decoction in addition to radiotherapy, while patients in the control group were treated with radiotherapy alone. Main outcome measures: The incidence rates of radiation pneumonitis in the two groups were calculated. Acute radiation injury scoring criteria by Radiation Therapy Oncology Group (RTOG), clinical-radiographic-physiologic (CRP) score system, and Karnofsky Performance Status Scale (KPS) were used to evaluate the status of the patients. Results: The incidence rate of radiation pneumonitis was lower in the treatment group than in the control group (13.04% versus 33.33%, P<0.05). According to the RTOG scale, the extent of lung injury was improved in the treatment group as compared with that in the control group (P<0.05). The CRP score in the treatment group was significantly lower than that in the control group (P<0.05). The KPS score in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion: Liangxue Jiedu Huoxue Decoction can decrease the incidence rate of radiation pneumonitis, reduce the extent of the lung injury, alleviate the symptoms of radiation pneumonitis, and improve life quality of the patients.

Objective To investigate the effect of astragalus polysaccharides (APS) on the differentiation of rat bone marrow mesenchymal stem cells (BMSCs) to neurones, adipocytes, osteoblasts and chondrocytes, and provide basis for the development of effective and low toxic differentiation inducing agents. Methods BMSCs were isolated from SPF Wistar rats, purified, expanded and cultured to family 3. The appropriate concentration of APS was filtered out by MTT assay. The F3 cells were randomly divided into control group and induced group (neural induction, adipogenic induction, osteogenic induction, cartilage induction). The effects of APS and classical chemical drugs on differentiation were measured by toluidine blue, oil red o and alizarin red staining. The protein expression of NSE, LPL, collagen Ⅰ and collagen Ⅱ were examined by Western Blot. Results MTT assay showed that 1 g/L APS promoted the proliferation better than other concentrations especially in 48 hours. The morphologic change of the cell from BMSCs was uniformly positive to toluidine blue staining, and was negative to oil red o and alizarin red staining. Western blot showed that the protein expression of the cell from BMSCs was positive for NSE but negative for LPL, collagen Ⅰ and collagen Ⅱ. Conclusion BMSCs induced by APS can differentiate to neurone and fail to differentiate to adipocytes, osteoblasts and chondrocytes in vitro.
