BACKGROUND: Levodopa substitutive therapy is essential and effective method for PD for a long time, but it can not delay the course of PD. Side effect is more and more and severe, for taking levodopa long term. It is benefit to patients to postpone the usage of levodopa or decrease the dosage of it.OBJECTIVE: To systematically investigate the curative effect of the selfmade Bushenpingchan formula combined with madopar on pathogenetic condition of PD patients after onset.DESIGN: Randomized controlled observation.SETTING: Senile Disease Research Center, Xuanwu Hospital, Capital University of Medical Sciences.PARTICIPANTS: Seventy patients diagnosed as having PD were recruited from the Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine between December 1999 and May 2002. Inclusive criteria: The patients must be diagnosed as PD finally; ②be at 1.5-4 grade of modified Hoehn & Yahr measuring scale; ③less than 80 years old; ④The Traditional Chinese Medicine (TCM) diagnosis was deficiency of liver and kidney. Exclusive criteria: ①secondary PD; ②accompanying with other sever central nervous system diseases. ③patients with severe diseases of heart,lung, kidney or multi-viscera-failure; ④mental sickness patients; ⑤drug and alcohol abuse; ⑥severe adverse effect.METHODS: Totally 70 patients were divided into two groups based on the proportion of one to one: There were 35 patients in treatment group containing 22 males and 13 females. The average age was (67.9±16.5)years. There were 35 patients in control group including 25 males and 10females. The average age was (65.5±16.5) years. There was no significant difference in their general condition. Patients in the control group received 62.5-500 mg madopar (250 mg in each pill), 2-4 times a day (to change the dose according to patients' condition). The patients in the treatment group were given with 62.5-500 mg madopar (250 mg in each pill), 2-4times a day orally and 200 mL self-made Bushenpingchan formula (twice a day) in addition, which was composed of 20 g tuber fleeceflower root, 1 g hairy deerhorn, 10 g tall gastrodia tuber, 15 g gambirplant, 12 g Chinese thorowax root, 15 g twolobed officinal magnolia bark, twice a day. The course of medication was 3 month in patients of the two groups. The patients were determined with unified Parkinson disease rating scale (UPDRS) before treatment and at weeks 2, 4, 8 and 12 after treatment, respectively. The symptoms in traditional Chinese medicine after treatment were measured. The dose of madopar before and after medication as well as the adverse effect were observed.MAIN OUTCOME MEASURES: Score of UPDRS before treatment and at weeks 2, 4, 8 and 12 after treatment in patients of the treatment group and control group; the dose of madopar before and after treatment and the adverse effect after treatment.RESULTS: Total effective rate was 69% and 51% in the treatment group and control group, respectively after treatment. There was no significant difference in therapeutic efficacy (x2=0.86, P=0.222 3). ①The score of UPDRS reduced significantly 8 weeks after treatment in the treatment group as compared with that before treatment (t=2.18 ,P ＜ 0.05). ②The daily dosage decreased in the patients of the treatment group after treatment as compared with that before treatment, which had significant difference (t =2.862 8,P ＜ 0.01 ). The daily dosage in the patients of control group had insignificant difference with that before treatment (t=2.320 3,P ＜ 0.01 ). ③There were 2 cases with lightly dry mouth, nausea, dizziness,which could relieve two weeks later in the treatment group; 5 patients with nausea and 2 patients with light dizziness in control group, which could relieve. The blood pressure had no significant change in the two groups before and after treatment.CONCLUSION: The Chinese medicine Bushenpingchan formula combined with western medicine can decrease the UPDRS score in PD patients,can improve the syndromes in Chinese medicine.

Objective To investigate the clinical manifestations and diagnosis and treatment of aortic dissection(AD).Methods The clinical data of 20 patients with aortic dissection were analyzed retrospectively.Results 20 patients were diagnosed by CT, MRI and colour ultrasonography (5,5,10 cases, respectively). According to DeBakey typing, this group of patients was composed of type I(11 cases, 55%), type II(2 cases, 10%)and type III (7 cases, 35%). All patients were treated with internal medicine ,average time in hospital stay was(29 8?25 5)days. The patients' conditions were improved in 19 person-times (76%). 4 patients died (20%) and 2 patients abandoned treatment (8%).Conclusions The accurate diagnosis as early as possible and active therapy was a key of improvment of prognosis in patients with aortic dissection.

Objective To obtain the protein interacting with inhibitor of differentiation1′(Id1′). Methods The recombinant bait plasmid pHybLex/Zeo Id1′ was constructed and transformed into yeast strain EGY48/ pSH18 34 to test pHybLex/Zeo Id1′ for non specific activation. Adult human lung cDNA libraries were screened to obtain true positive library plasmid. The true positive library clone was obtained by sequencing and basic local alignment sequence tool (BLAST). Results The recombinant bait vector, named as pHybLex/Zeo Id1′, was confirmed by sequencing. pHybLex/Zeo Id1′ was transformed into yeast strain EGY48/pSH18 34 and the transformants had no autonomously activated reporter genes. One true positive clone, obtained by screening of the adult human lung cDNA libraries, was confirmed to be Fyn by sequencing and BLAST. Conclusion Id1′ can interact with Fyn.

Objective To investigate the prevention and treatment effects of Compound Kushen Injection on acute radiation esophagitis. Methods Eighty-two eligible patients with esophageal cancer were randomly divided into the treatment group (41 cases) and the control group (41 cases). All the patients received radiotherapy. Throughout the course of radiotherapy, patients in the treatment group received Compound Kushen Injection, and patients in the control group received Kangfuxin Liquid. Occurrence time and level of radiation esophagitis, and dosage of painkillers were observed. Results Different degrees of acute esophageal toxicity were observed in the two groups. The occurrence rate of high level (degree III and degree IV) acute radiation esophagitis was 7.3%(3/41) in the treatment group, and 31.7%(13/41) in the control group. There was significant difference between the two groups (P<0.05). The dosage of the analgesic drug (Fentanyl Transdermal System) in the treatment group was far less than the controlled group (P<0.001). Conclusion Compound Kushen Injection could decrease the incidence rate of acute radiation esophagitis, and reduce the high-level esophagitis and the dosage of the analgesic drug, which can help the completion of radiation.

Objective To investigate the effects of exercise therapy and health education on the hospitalization and exercise endurance of patients with moderate or severe chronic obstructive pulmonary disease (COPD).Methods A total of 86 patients with moderate or severe but stable COPD were divided randomly into an observation group (n=46) and a control group (n=40).The patients in both groups accepted general respiratory medical therapy.The patients in the observation group also accepted additional pulmonary rehabilitation therapy which consisted of exercise and health education while the patients in the control group only accepted health education and rehabilitation training guidance by telephone instead of standardized pulmonary rehabilitation therapy.The average recurrence of hospitalization,length of stay,and total bed time of all of the patients was tracked for a year before and after enrolment.Their 6 minute walking distance (6MWD) and quality of life (QOL) as reflected by using a scale recommended by the Chinese Society of Respiratory Disease before and after entering the study were evaluated.Results There was no significant difference between the groups in the year before entering the study in terms of their average frequency of hospitalization,length of stay or total bed time.In the year after enrollment average frequency of recurrence requiring hospitalization,length of stay and total bed time in the observation group all decreased significantly compared with the previous year,and all were significantly lower than in the control group.There were no significant differences between the groups in average 6MWD or average QOL score at entry,but in the subsequent year both groups' results improved significantly.Conclusion Long term pulmonary rehabilitation can not only enhance exercise endurance,it also improves QOL and relieves the economic burden of COPD patients on society.

Objective To discuss MRI characteristics and differential diagnosis of fourth ventricular masses. Methods We retrospectively analyzed 90 cases' MRI findings of fourth ventricular masses that were proved by the surgery (n=83) or were diagnosed by more than three professors and assistant professors in the neuroradiology field (n=7). Results These masses in our study included the medulloblastomas (n=27),the ependmomas (n=18),the choroid plexus papillomas (n=11),the metastases (n=7),astrocytoma (n=6),astrocytomas and glioma (undifferentiated and mixed patten are 5cases),epidermoid cysts (n=5),cerebral cysticercosis (n=4),cavernous hemangiomas (n=4),venous malformation (n=3). Their shapes were spheroridal or irregular,and some masses could become cystic changes in the masses. Most masses could be enhanced or a few couldn't be enhanced with DPTA on MRI. Conclusion The demonstration of fourth ventricular depends on MR findings. It is important to differentiate these masses between within and without fourth ventricular for the differential diagnosis.
