Objective: To explore the compatibility and application methods of clinical formulas.Methods: In the guidance of monarch,minister,assistant and guide theory, the constructions of prescription were divided into principal agents and lesser agents;500 prescriptions were from 1000 set prescriptions and empirical formulas recorded in pharmacology of traditional Chinese medical formulae teaching material and well-chosen efficacy nostrum written by national lever famous veteran teran doctors of TCM.Then they were analyzed to study the constituting formats of(clinical) formulas and the derivation methods of set prescriptions in clinical application.Results: Through analysis,we found the constituting formats of formulas in terms of single taste single group having principal agents but lesser agents(12.3%),multitude groups having principal agents but lesser agents(13.7%),single taste or single group principal agents with one group lesser agents(14.4%),multitude groups principal agents with one group lesser agents(17.7%),single taste or single group principal agents with multitude groups lesser agents(18.3%) and multitude groups principal agents with multitude groups lesser agents(23.6%) et al.From the 500 randomly extracted prescriptions,among 68.4% prescriptions were present derivation relationship,that is,for adapting new pathogenesis conditions,through methods in terms of replacing principal agents(10.2%),mild recipe lowering to lesser agents(17.0%),two formulas to put together(14.3%),expanding principal agents(16.4%),changing lesser agents(18.7%),principal agents pero-replacing(10.2%) and others(13.2%),changed constituted relation of principal agents or lesser agents,so to generate several formulas possessing new effect characteristics.Conclusion: The(divide) of principal agents and lesser agents has a universal applicability in analyzing the constitutions of formulas;the clinical application and derivation methods of set prescriptions revealed by this method have guide effect to initial(experiencing) clinical worker.

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

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.
