Objective To investigate the levels of cystatin C (CC) with the H&Y scale and duration of Pakinson's disease(PD)patients.Methods The study consists of 432 PD patients and 513 control subjects.PD patients were divided into 3 subgroups according to their H&Y scale.The levels of CC and Scr were measured.The statistics analysis was used to evaluate their associations.Results In PD and control groups, CC concentrations were significantly different (P ＜ 0.05), and Scr concentrations in two study groups were not significantly different(P ＞ 0.05).PD in each subgroup, CC concentrations in the medium group were significantly higher than the early and control groups, and CC in the late group was significantly higher than the other two subgroups.Rank correlation analysis and comparison of CC concentration and duration and H&Y score showed that CC concentration was positively correlated with the duration of PD(r =0.209, P ＜0.01), and that CC concentration and H&Y score were significantly positively correlated (r =0.618, P ＜0.01).Conclusions There was a certain correlation between CC levels and PD, and CC levels of PD patients were significantly higher.There was no significant increased CC in the initial stages of the disease, perhaps CC was not necessary cause of the onset of PD.However, the level of CC with H&Y stage and duration were positively correlated, perhaps CC may be involved in the process of disease progression, because high level of CC may increase PD patient's condition.

Methods The self-designed psychological questionnaire was used to investigate 138 medical staff’s psychological condition in a general hospital. Results When sudden public health accidents came, the medical staff’s positive cognizance, positive and negative response, and positive emotion exhibited significant difference according to which wards they worked in and what professional background they possessed(P

Objective:To investigate whether the likelihood of balance impairment in children with attention deficit hyperactivity disorder(ADHD) increases with the presence of disruptive behavior disorder(DBD),and whether the likelihood of co-occurring diagnosis of DBD increases in ADHD children with severer balance deficit.Methods:Three groups of 20 children each,representing pure ADHD,ADHD+DBD,and typically developing control children,were included and group matched by age and gender.Balance functions were assessed with the Balance Master in different conditions.We compared the percentages of children in each group who swayed faster than 85% of the typical control children in all conditions.Results:In the conditions of firm surface with eyes open(FI/EO) and eyes closed(FI/EC),and foam surface with eyes open(FO/EO) and eyes closed(FO/EC),the sway velocities of ADHD only group(0.65?0.26 ?/s,0.65?0.30 ?/s,0.95?0.29 ?/s,and 1.70?0.49?/s,respectively) were significantly higher than those of the typical control group(0.47?0.18 ?/s,0.43?0.19 ?/s,0.76?0.21 ?/s,and 1.27?0.38 ?/s,respectively)(P

Objective To explore the effect of externally-applied white plaster on cervical radiodermatitis.Methods Ninety patients with cervical radiodermatitis were equally divided into the observation group and control group according to their admission order.Patients in the control group were treated with furacilin through moist packing as well as routine nursing and the patients in the observation group were given white plaster for external application as well as nursing healthcare education.The two groups were compared in terms of clinical effect,average treatment during,and adverse reactions.Results The total effectiveness rate in the observation group was significantly higher than that of the control group and the average treatment duration was significantly shorter (P<0.05).There were no obvious adverse reactions in both groups.Conchusions The white plaster is clinically effective for the treatment of cervical radiodermatitis.It is advantageous due to shortened curative course and no adverse reactions.

Objective:To investigate the effects of monotherapy of SSRI and SSRI with psychotherapy on patients of somatoform disorders.Methods:96 patients who met the criteria of CCMD-3 for somatoform disorders were divided into three groups:group one taking Fluoxetine only;group two taking Fluoxetine and a small dose of Olanzapine;group three combining the above two medicines with Gestalt psychotherapy.Before treatment and after three months' treatment,the effects of each group were evaluated by scores of HAMD.Results:According to the effective rate within each group(53.1%、61.8% and 96.7%),there was significantly differences in three groups after three months treatment(?2=15.5,P

Objective To compare the curative efficacy and safety of subcutaneous immunotherapy (SCIT) versus sublingual immunotherapy (SLIT) for allergic rhinitis.Methods A total of 127 cases of patients with allergic rhinitis in the outpatient department of our hospital from June 2009 to March 2016 were retrospectively analyzed,including 79 cases treated with SCIT and 48 cases treated with SLIT.The curative effects and adverse reactions were compared between the two groups.Results After 3-year treatment,the total effective rate in the SCIT group was 75.9%,which was higher than 72.9% in the SLIT group,but the difference was not statistically significant (χ2=0.15,P>0.05).The incidence rate of adverse reactions in the SCIT group was 26.6%,which was higher than 10.4% in the SLIT group,the difference between the two groups was statistically significant (χ2=4.79,P<0.05).Conclusion The two desensitization treatment methods all gain better effect,but SLIT has lower occurrence rate of adverse reactions.

Objective To explore the clinical effect of atomoxetine on children with attention deficit hyperactivity disorder(ADHD)comorbid tic disorder.Methods The children who met the criteria of Mental Disorders Diagnostic and Statistical Manual diagnostic criteria for ADHD and tic symptoms were given systematic atomoxetine titration reaching the optimum dose.ADHD and tic symptoms were evaluated with ADHD rating scale-Ⅳ(ADHD-RS-Ⅳ)for parents Yale Global Tic Severity Scale(YGTSS),respectively.Results Twenty children with ADHD comorbid tic disorder [17 male,3 female;age range 7.58-17.0 years,mean age(10.55?2.58)years] completing systemic titration was enrolled in the study,including 10 subjects with ADHD-inattentive type,9 mixed type,and 1 hyperactive/impulsive type.The mean optimal dose was(1.19?0.21)mg/(kg?d).The total score(12.65?9.08)scores,inattention score(7.45?4.75)scores and hyperactivity/impulsivity score(3.0)of ADHD-RS-Ⅳ decreased significantly post-treatment compared with pro-treatment(31.10?8.52,17.60?3.09,and 13.0 scores,respectively,P

Notoginseng Radix et Rhizoma (Sanqi), the underground part of Panax notoginseng (Burk.) F. H. Chen (Araliaceae) is commonly used in Chinese medicine for treatment of haemorrhage, haemostasis, swelling, etc. The aerial part including leaves, flowers and fruits are also applied for similar functions. Triterpenoid saponins are considered to be responsible for the biological activities of Sanqi. Up to date, more than 100 saponins have been isolated from theroots, rhizomes, leaves, flowers and fruits of P. notoginseng. The reported saponins can be classified into protopanaxadiol (PPD), protopanaxatriol (PPT), C17 side-chain varied and other types, according to the skeletons of the aglycons. The present review summarizes the saponins isolated from P. notoginseng and their distribution in different medicinal organs, as well as the pharmacological actions on cardiovascular system.

BACKGROUND: One of the key neuropathological changes in Alzheimer disease is that neurofibrils over phosphorylated cytoskeletal protein (such as r and neurofilaments) composed of entwist together, and the phosphorylation of τ protein can be catalyzed by cyclin dependent kinase 5 (CDK5),however whether the phosphorylation of neurofilaments can be catalyzed by CDK5, as well as its role in the pathogenesis of Alzheimer diseases is less acknowledged.OBJECTIVE: To explore the role of over-expression of intracellular CDK5 in the phosphorylation of neurofilamentsDESIGN: Randomized controlled study.SETTING: Biochemical and Molecular Biological Department of Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: This study was conduced at Biochemical and Molecular Biological Department of Tongji Medical College, Huazhong University of Science and Technology between February and May 2001. In vitro cultured rat neuroblastoma cell strain (N2a) was adopted as subjects.METHODS: In vitro cultured N2a cells were divided into 2 groups, namely transfection group and non-transfection group. In transfection group,CDK5 gene was transfected into N2a cell line by using liposome transfection technique so as to obtain N2a/CDK5 cell line stably expressing CDK5, immune-precipitation and enzyme activity assay was used to detect the CDK5 activity, meanwhile immunofluorescence technique and immuneblot assay was used to detect CDK5 expression and phosphorylation of neurofilaments.MAIN OUTCOME MEASURES: Phosphorylation of neurofilaments in both groups.RESULTS: In transfection group of N2a cell line, CDK5 expression increased presented by deep coloration of SMI31 antibody and weak coloration of SMI32 antibody, implying hyper-phosphorylation of neurofilaments. Meanwhile, the activity of CDK5 was 3.5 times higher than that in non-transfection group.CONCLUSION: Intracellular over-expressison of CDK5 would lead to hyperactivity of CDK5 and hyper-phosphorylation of neurofilaments, however the hyper-phosphorylation of neurofilamentsmight invlove in the pathological development of AD.
