Molecular immunologic technique gets quick development in recent years, especially the fast development of the immuno-labelling technique, which found its indispensable status in the study of traditional Chinese medicine (TCM). With the development of the study of TCM, medical immunology connecting TCM with the Western medicine has become one of the most indispensable conjunctive subjects. Scientists can study the theories and prevention or treatment mechanisms of TCM not only at holistic and cell levels, but also at molecular and gene levels. Appropriate application of the molecular immunologic techniques according to their characteristics will play an important role in the study of Chinese integrative medicine.

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

Objective To observe the effect of Pingchuanlingchongji (PCL) on the auricular microcirculation of mice and to investigate the effect mechanism of the treatment for asthma. Methods 50 mice were randomly divided into five groups, group 1 and group 2 were given 0.9% NS (25 mL/kg) as control group; group 3 was given aspirin (0.25 g/kg), 4 group was given low-dose (1.1 g/kg) PCL, group 5 was given high-dose (2.2 g/kg) PCL. Last for seven days. We injected Posterior Pituitary Injection (0.5 U/mL) on the rear vein of 2-5 group mices after the last time of given druy. The diameter of micro-artery in mice auricular, the diameter of micro-vein and blood flow speed were observed. Results As compared with contral group, PCL could expand significantly the diameter of micro-artery and the diameter of micro-vein in mice auricular (P

Objective To evaluate the effects of different doses of propofol infusion on real-time monitoring of recurrent laryngeal nerve. Method 30 ASA Ⅰ-Ⅱ patients who underwent thyroid gland surgery were given propofol intravenously in different concentrations. BP, HR and real-time monitoring of recurrent laryngeal nerve were recorded with the propofol dosage varying from 3 to 6, 9, 12, 15, 18?g/(kg?min). Results The amplitude of recurrent laryngeal nerve reflex had no change with different doses of propofol infusion. The HR and BP were elevated with low doses of propofol infusion, but there were no changes when propofol concentration was 15 or 18?g/(kg?min). Conclusion Propofol infusion i.v. does not interfere with real-time intraoperative monitoring of recurrent laryngeal nerve, and it does not inhibit the action potential of recurrent laryngeal nerve, but can effectively decrease the cardiovescular reaction.

Objective To study the diagnosis and treatment of adrenocorticotrophic hormone (ACTH) independent Cushing syndrome. Methods A retrospective review was done on 89 patients with ACTH independent Cushing syndrome, including 85 cases of adrenal tumors with hypercorticism, 2 cases of adrenocortical adenocarcinoma and 2 cases with ACTH independent macronodular adrenal hyperplasia. Results Favorable results were observed from the surgery for 85 cases of adrenal tumors combined with hypercorticism.Two cases with ACTH independent macronodular adrenal hyperplasia were cured by bilateral adrenolectomy. Adrenal cortical adenocarcinoma was unresectable for both the patients who survived 7 and 9 months respectively. Plasma ACTH,dexamethasone suppression test,B ultrasonography and CT scan were useful for the diagnosis and differentiated diagnosis of ACTH independent Cushing syndrome. Conclusions Prognosis of adrenal tumors with hypercorticism and ACTH independent macronodular adrenal hyperplasia is favorable after surgery,whereas the prognosis of adrenal cortical adenocarcinoma is poor.

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 compare the effectiveness and safety of glucocorticoid versus intravenous injection of human immunoglobulin (IVIG) in treatment of with acute primary immune thrombocytopenia (ITP) in children. Methods PubMed, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, Chinese biomedical literature database (CBM), Chinese Journal Full Text Database (CNKI) and Wanfang database were searched. The bibliography was screened according to the inclusion and exclusion criteria,and the target literatures were selected. The data were extracted and the quality of included literatures was evaluated. Revman 5 . 3 software was used to make meta-analysis. Results In 1500 papers searched, 8 papers met the inclusion criteria. Meta-analysis showed that there was a statistical signiifcance in platelet count (PLT,>20 × 109/L) after being treated for 48 h between glucocorticoid group and IVIG group (RR=0 . 77 , 95%CI:0 . 67~0 . 89 ). In subgroup analysis, there were statistical signiifcance in methylprednisolone (MP) 30 mg/kg versus IVIG 1 g/(kg·d)× 2 d, and metacortandratin (PDN) 4 mg/kg versus IVIG 1 g/(kg·d)× 2 d (RR=0 . 66 , 95%CI:0 . 47-0 . 91;RR=0 . 79 , 95%CI:0 . 66-0 . 95 ). After treatment for 24 h and 72 h, the platelet count>20 × 109/L were signiifcantly different in glucocorticoid group and in IVIG group (RR=0 . 69 , 95%CI:0 . 53-0 . 91;RR=0 . 82 , 95%CI:0 . 74-0 . 90 ). Moreover, after treatment for 24 h, 48 h and 72 h, the platelet count>50 × 109/L were signiifcantly different between glucocorticoid group and IVIG group (RR=0 . 38 ,95%CI:0 . 21-0 . 69;RR=0 . 53 , 95%CI:0 . 41-0 . 69;RR=0 . 80 , 95%CI:0 . 70-0 . 93 ). There was no difference in the incidence of splenic resection between two groups (RR=5 . 41 , 95%CI:0 . 95-30 . 74 , P=0 . 06 ). Conclusion The probability of platelet count to reach>20 × 109/L in the initial treatment with glucocorticoid of acute ITP patients were 32%lower than that with IVIG. With the initial therapeutic target being platelet count>50 × 109/L in 3 days, the effect of IVIG was better.

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.
