Objective To evaluate the therapeutic effect of Xifeng Dingchan Pill (Pill for stopping wind and tremor) on Parkinson's disease (PD).Methods Sixty PD patients were randomized into a treatment and a control group. The treatment group (30 cases) was given madopar and Xifeng Dingchan Pill and the control group (30 cases) was administered madopar only. The effect Xifeng Dingchan Pill was evaluated according to the changes of Webster score and PD symptom factor score.Results The total effective rate of the treatment group was 76.67%, higher than 53.33% in the control group (P

Objective To approch the characteristic of diagnosis and treatment of optic nerve injury in double wall optic canal.Methods Six patients,with double wall optic canal found by CT,were treated by drug,operation and visual rehabilitation training.The results of CT,vision-evoked potential and visual recovery were analysed.Results In 6 patients,4 were holo-double wall optic canal and 2 were mero-double wall optic canal,4 were found having bone fracture.All the 6 cases were effective to treatment including 3 patients whose vision was over 0.1.Conclusion In double wall optic canal,the degree of optic nerve injury is slight,visual recovery is better by drug,operation and visual rehabilitation training.

Objective:To explore the independent risk factors that predict 10-year mortality in patients with stable chronic obstructive pulmonary disease(COPD).Methods:The baseline data from a prospective cohort study were analyzed and long-term follow-up were performed. Patients with confirmed diagnosis of stable COPD were consecutively enrolled in the outpatient clinic from January 2010 to December 2010, and were followed up until December 31, 2020. Cox regression analysis was used to determine the independent risk factors for all-cause mortality and mortality from respiratory causes in stable COPD patients.Results:A total of 182 stable COPD patients were enrolled and followed up for a median of 89 months. The 10-year mortality was 51.1%(93/182), and 9 patients died within one year. The leading cause of death was respiratory disorder, followed by cardiovascular and cerebrovascular diseases. The risk factors independently associated with all-cause mortality included old age( HR=1.936,95% CI: 1.610~2.328, P<0.01), increased baseline COPD Assessment Test(CAT)( HR=1.331,95% CI: 1.049-1.689, P=0.02) and the increased CAT in one year( HR=1.314,95% CI: 1.197-1.420, P<0.01). The risk factors independently associated with respiratory cause mortality included increased baseline CAT( HR=1.719,95% CI: 1.026-2.880, P=0.04), emphysema index(LAA%)( HR=1.062,95% CI: 1.007-1.120, P=0.03), and one year inecreased CAT( HR=1.342,95% CI: 1.198-1.505, P<0.01)was a protective factor. Conclusions:Old age, baseline CAT, one year increased in CAT and LAA% were independent influencing factors for 10-year mortality of stable COPD patients.

AIM:To observe the intervention ef-fect of Chinese medicine Kangzhen Zhijing spas-modic decoction Ⅰ on the progression of Parkin-son's disease in mice,and to explore the potential mechanism of neuroprotection.METHODS:Thirty-six C57BL/6 mice were randomly divided into con-trol group,model group,drug group and positive drug group.In the model group,the drug adminis-tration group and the positive drug group,1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)(30 mg/kg)was injected intraperitoneally for 5 days to establish the mouse model.The control group was given the same amount of normal saline,the drug administration group was given 1.25 mg/kg,2.5 mg/kg,5 mg/kg dose of Chinese medicine Kang-zhen Zhijing spasmodic DecoctionⅠby gavage,and the positive drug group was given 75 mg/kg Madopar by gavage.Behavioral tests were per-formed on the second day after the administration in each group.Immunopositive cells of Tyrosine hy-droxylase(TH),Amyloid precursor protein(APP),α-synuclein(α-syn)and solute carrier family 6 mem-ber 11(SLC6A11)were detected by immunohisto-chemistry.The protein expressions of TH,APP,α-syn and SLC6A11 in each group were detected by Western blot.RESULTS:It could significantly im-prove the weight loss of mice in the model group,alleviate the decline of autonomic activity in open field test and the decline of coordination ability in pole test and suspension test.In the reverse immu-nohistochemistry and Western Blot experiments,the expressions of TH and SLC6A11 in the brain of the Parkinson's model group were significantly de-creased,and the expressions of APP and α-syn were significantly increased.CONCLUSION:Kang-zhen Zhijing spasmodic decoctionⅠcan significantly improve the behavioral performance of Parkinson's disease mice and effectively improve the reduction of neuronal transmitters.
