Objective To study the incidences of falls in patients with Parkinson's disease and analyze the related factors.Methods The clinic data of 100 Parkinson's patients were retrospectively analyzed to investigate the fall incidence and the related factors.Results The fall incidence was 46.0%during hospitalization in the patients with Parkinson's disease.The single factor analysis showed that the falls incidence were higher in male patients,dizziness from drug factors,a history of falls and non-presence of their families during hospitalization than those in the non-fall group(P<0.05).Logistic regression analysis showed that male patients,dizziness from drug factors,a history of falls and non-presence of their families during hospitalization were risk factors for Parkinson's patients during hospitalization.(all P<0.05). Conclusions The high risk factors for the falls in Parkinson's patients include male patients,dizziness from drug factors,a history of falls and non-presence of their families during hospitalization.Therefore,the assessment of the risk factors for falls should be done so as to carry out fall factors control and fall risks classification management for the purpose of reducing falls.

Aiming at the weakness of the medical graduate students' ideological and political education,we developed the new mode via investigation and surveying,allowing for the medical characteristics. We suggested that we should bring into full play the tutors and their groups function and excavate the connotation of groups’ morality education on the basis of the scientific research groups to develop the medical students' ideological and political education.

Transcatheter arterial chemoembolization (TACE) is the first choice of patients with hepatocellular carcinoma (HCC) missed opportunity of exairesis.Angiogenesis is one of the key factors that affect prospective efficacy.Counter-measures against angiogenesis mainly contain complete embolization of tumor blood supply and integration with angiogenesis inhibitors.The angiogenesis after TACE and the corresponding countermeasures were reviewed in this article.

Objective To evaluate the toxicological safety of Shanze weight-reducing food in order to provide some toxicological data for its application. Methods According to the national standard of safety evaluation, the following experiments of acute toxicity test through mouth in rats, the genetic toxicity test, thirty days feeding test and teratogenicity test in mice were performed. Results LD 50 was more than 20.0 g?kg -1, equivalent to 467 times of the recommended dosage, in acute toxicity test through mouth in both male and female rats, which fell into the scale of non-toxicity. Under the dosage range of 1.05 g?kg -1 to 4.20 g?kg -1, equivalent to 100 times of the recommended, the negative results were observed in the genetic toxicity test of micronucleus test of bone marrow cells, sperm shape abnormality test in mice and the Ames test. The negative impacts on the growth, development, hematology, biochemistry, histology and the ratio of organ to whole body were not found on the experimental rats of thirty days feeding. Under the same dosage range, no teratogenic effects were found in the experiments of teratogenicity test. Conclusions Shanze can be used as a kind of health weight-reducing food with toxicological safety under the experimental dosage range of 1.05 g?kg -1 to 4.20 g?kg -1.

Background Cardiomyocytes apoptosis was related to oxidative stress which has been shown to play an important role in ventricular remodeling after myocardial infarction(MI).Probucol is a hypolipidemic and antioxidant agents.Several reports demonstrated its cardioprotective effect after MI.However,the exact effect of probucol on the modification of the apoptosis related gene Bcl-2 and Bax is not clear.Objective To investigate the effects of probucol on mRNA and protein expression of Bcl-2,Bax and oxidative stress in myocardial infarcted rats.Methods Forty-one SD rats that survived 24 h after ligating left anterior descending coronary artery were randomly to receive placebo-saline(5 mL/d,n=20)or probucol(probucol 60 mg/kg?d,n=21).Twelve rats underwent sham operation were served as control(n=12).Six weeks after treatment,hemodynamic pararmeters and left ventricular function were measured with catheterization.Cardiomyocytes apoptosis were determined by TUNEL method.Myocardium mRNA of Bcl-2 and Bax expression levels in the non-infarcted myocardium were as- sessed by RT-PCR.The myocardium protein expression of Bcl-2 and Bax in the non-infarcted myocardium were de- termined by Western blot.Colorimetry was used to determine oxidative metabolism index in myocardium.Results 1)Compared with the sham rats,all MI rats showed marked decrease in Bcl-2 mRNA and protein expression in myo- cardium with increase of Bax mRNA and protein expression and apoptosis index(P

Objective To evaluate the effect of penehyclidine hydrochloride (PHC) on the level of angiopoietin-1 (Ang-1) and tyrosine kinase receptor-2 (Tie-2) during endotoxin-induced acute lung injury (ALI) in rats.Methods Forty adult male Sprague-Dawley rats,weighing 180-220 g,were randomly divided into 4 groups using a random number table (n =10 each):control group (group C),ALI group,low-dose PHC group (group L-PHC) and high-dose PHC group (group H-PHC).ALI was induced with iv injection of lipopolysaccharide 5.0 mg/kg via the tail vein.In L-PHC and H-PHC groups,PHC 0.6 and 2 mg/kg were injected,respectively,via the tail vein at 1 and 24 h after lipopolysaccharide injection.The rats were sacrificed at 48 h after the initial injection of PHC to measure the lung water content,protein concentration in bronchoalveolar lavage fluid (BALF),and the expression of Ang-1,Tie-2 and phosphorylated Tie-2 in lung tissues.The morphological changes of lung tissues were observed under light microscope and the ultrastructural changes of alveolar epithelial barrier under transmission electron microscope.Results Compared with group C,the lung water content and protein concentrations in BALF were significantly increased,and the expression of Ang-1 and phosphorylated Tie-2 was down-regulated in the other three groups (P ＜ 0.05).Compared with group ALI,the lung water content and protein concentrations in BALF were significantly decreased,and the expression of Ang-1 and phosphorylated Tie-2 was up-regulated in H-PHC group (P ＜ 0.05),and no significant changes were found in the parameters mentioned above in group L-PHC (P ＞0.05).The damage to lung tissues was significantly reduced in group H-PHC as compared with group ALI.Conclusion PHC can improve the permeability of pulmonary microvascular and reduce injury to alveolar epithelial barrier,thus ameliorating endotoxin-induced ALI in rats,and the effect is dose-related and up-regulation of Ang-1 expression and inhancement of Tie-2 activity are involved in the mechanism.

Objective To investigate the correlation of serum anti-M-type phospholipase A2 receptor (PLA2R) antibody with laboratory parameters of idiopathic membranous nephropathy (IMN) in adult patients with membranous nephropathy (MN),and to explore the role of anti-PLA2R antibody in the pathogenesis of IMN. Methods Forty-six adult patients with biopsy-proved glomerular diseases were involved in this study,including 20 cases with IMN,7 cases with IgA nephropathy (IgAN),6 cases with hepatitis B-associated membranous nephropathy (HBV-MN),6 cases with minimal change nephropathy (MCN),4 cases with focal segmental glomerulosclerosis (FSGS) and 3 cases with class Ⅴ lupus nephritis.Total RNA was extracted from human glomeruli and was reversely transcribed to the first-strand cDNA.The full-length human M-type PLA2R was amplified by PCR and the 605 bp product was subcloned into eukaryotic expression vector containing CMV promoter.The recombinant human M-type PLA2R plasmid vector was transiently transfected into human embryonic kidney (HEK) 239T cell line using the FuGene6 transfection reagent.Western blotting was used to detect serum anti-PLA2R antibodies.Correlations of antiPLA2R antibody level with laboratory parameters,including serum albumin,total cholesterol,Scr and 24-hour urine protein,of IMN patients were evaluated. Results Among 20 cases with IMN,15 cases showed positive anti-PLA2R antibodies (positive rate 75％).Of 7 cases with IgAN and 6 cases with HBV-MN,only 1 case showed positive anti-PLA2R antibody respectively (positive rate 14.29％ and 16.67％ respectively).Anti-PLA2R antibody was negative in other patients.The positive rate of anti-PLA2R antibody in IMN patients was significantly higher than that in patients with secondary MN and other types of glomerlonephritis (all P＜0.01).Furthermore,anti-PLA2R antibody level was positively correlated with 24-hour urine protein(r=0.803,P＜0.01) and negatively correlated with serum albumin in IMN patients (r=-0.816,P＜0.01). Conclusions The high positive ratio of anti-PLA2R antibody may indicate that it is the specific autoantibody in IMN.AntiPLA2R antibody is correlated with IMN disease severity,which indicates that it may be the pathogenic autoantibody in IMN.

OBJECTIVE: To observe the changes of volt-ampere characteristics of Yuan-Primary acupoints in women before, during and after menstruation, and to find out the relationships between Qi-blood in human body and volt-ampere characteristics of acupoints, so as to develop a new method for quantitative analysis on changes of Qi-blood. METHODS: A high-sensitive detection system of volt-ampere characteristics of acupoint was applied to detecting the volt-ampere characteristics of Taiyuan (LU 9), Daling (PC 7) and Shenmen (HT 7) in healthy women before, during and after menstruation. RESULTS: The resistances on LU 9, PC 7 and HT 7 with some certain scan currents were quite different among the women before, during and after menstruation. For such changes, PC 7 was of the most obvious change, LU 9 was of the less and HT 7 was of the least. The total ratio of the scanning spots with significantly increasing changes of resistances on these three acupoints along with the menstrual process was 70.6%. CONCLUSION: The volt-ampere characteristics of acupoints vary with the menstrual process, which is of the acupoint specificity. The resistances on the acupoints increase with the menstrual process, and such results may be due to the blood loss during menstruation. The volt-ampere characteristics can be used as a quantitative index to study on the change of Qi and blood.
