ObjectiveTo evaluate the safety and efficacy of GM1 ganglioside treatment for persons with Parkinson's disease.Methods33 Parkinson's disease patients with a fluctuating response to levodopa received 100 mg GM1 ganglioside (used as add-on agent to the previous medication regimen) daily. Unified Parkinson's disease Rating scale (UPDRS) motor score and Activities of Daily Living (ADL) score were measure before and 2, 3 or 4 weeks after treatment. The side-effect of GM1 during treatment were observed. ResultsAfter 2, 3, 4 weeks of treatment, There was significant improvement in patients with GM1 treament on the UPDRS motor scores were (23.5±8.9), (22.8±8.3) and (22.5±9.1) respectively, which was improved compared with that before (36.7±10.2) (P<0.01). The ADL portion of the UPDRS at these time were (21.4±10.9), (20.3±9.5) and (20.6±10.2) respectively, also showed significant improvement compared with the baseline (30.5±12.1) (P<0.01). However, there was no significant differece between the scores that measured at the time spots 2 weeks after treatment.No side-effect had been observed.ConclusionGM1 ganglioside can improve neurologic function significantly in PD patients with fluctuating response to levodopa.

Taking hyperthyroidism, anti-hyperthyroidism drugs and anti-hyperthyroidism combination as the keywords, 121 litera-tures on hyperthyroidism treatment were reviewed on CNKI and VIP database, and among them, 37 ones were selected as the represent-ative references. The clinical application was reviewed and summarized. Thiourea drugs are the first choice in the clinical treatment of hyperthyroidism;however, they show obvious side effects. Therefore, the drug combination use, especially the combination of Chinese and western medicines was proposed, which could rapidly improve the symptoms and the quality of life, reduce the dosage of western medicines and adverse reactions, and consolidate the curative effect and prevent the recurrence.

Objective To determine whether Ca2+ activated Cl- current(Icl(Ca)) contributes to the functional remodeling of the failing heart.Methods Whole cell patch-clamp recording technique was employed to record the Icl(Ca) in cardiac myocytes enzymatically isolatedfrom rapidly pacing induced canine failing hearts at room temperature and compared that of the normal hearts (Nor).Results Thecurrent density of DIDS(200M)sensitive Icl(Ca) induced by intracellular Ca2+ release trigged by L-type Ca2+ current(Ica,L)wassignificantly decreased in heart failare(HE)cells compared to Nor cells.At membrane voltage of 20mV,the Icl(Ca) density was 3.02±0.54 pA/pF in Nor(n=6)vs.1.31±0.25 pA/pF in HF(n=8)cells,(P＜0.01),while the averaged Ica,L density did not show differencebetween two groups.The time constant of current decay of Icl(Ca) was similar in both types of cells.On the other hand,in intra cellularCa2+ clamped mode,where the[Ca2+];was maintained at 100nmol/L,Icl(Ca) density be increased significantly in HF cells when themembrane voltage at+30mV or higher.Conclusions Our results suggest that Icl(Ca) density was decreased in pacing induced failingheart but the channel function be enhanced.Impaired Ca2+ handing in HF cells rather than reduced,Icl(Ca) channel function itself may havecaused this abnormality.The Icl(Ca) density reduction might contribute to the prolongation of action potential in failing heart.The Icl(Ca)channel function up-rugulation is likely to cause cardiac arrhythmia by inducing a delayed after depolarization,when Ca2+ overloadoccurred in diastolic failing heart cells.

Objective To analyze the prevalence rate and risk factors for aspiration pneumonia in elderly inpatients,and to identify a high-risk population for aspiration pneumonia.Methods Totally 398 inpatients aged ≥ 60 years in Beijing Hospital from April 2014 to April 2015 were selected.A questionnaire survey was performed for aspiration risk factors,including gender,age,smoking and drinking history,swallowing function,basal diseases,medication history,activities of daily living(ADL),occurrence of aspiration pneumonia over the past year.The patients were divided into aspiration pneumonia group and non-aspiration pneumonia group,and the prevalence rate and risk factors for aspiration pneumonia were studied.Results 364 cases with complete data were collected,and 14.3％ (52/364)were identified definitively as aspiration pneumonia over the past year.The ADL score was (77.0± 33.9) scales in aspiration pneumonia group,and (88.0 ± 22.2) scales in non-aspiration pneumonia group,with statistically significant difference (P＜ 0.05).The incidence rate of aspiration pneumonia was increased along with the increase of the age of patients.Risk factors for aspiration pneumonia were different in different age group.The proportion of patients aged 60-69,70-79 and over 80 years were 23.1％ (12 cases),36.5％ (19 cases),40.4％ (23 cases)in the aspiration pneumonia group,respectively.Under the condition of a propensity score-matched case-control pair design on 104 subjects with versus without aspiration pneumonia,the logistic regression analysis showed that smoking history,coronary heart disease,Parkinson's disease,dementia,chronic obstructive pulmonary disease(COPD),gastro-esophageal reflux disease(GERD),long-term uses of theophylline,calcium antagonists,nitrates,diazepam,antidepressants,anti-Parkinson drugs were the risk factors for aspiration pneumonia in elderly(all P＜0.05).Conclusions Smoking history,basal diseases and medication history are associated with the incidence rate of aspiration pneumonia in elderly.Assessment of these risk factors for aspiration pneumonia should be emphasized,and preventive measures should be considered conscientiously to lower the incidence rate of aspiration pneumonia in elderly.

Objective To explore the application of project management theory in spinal orthopedic nursing personnel training. Methods Project management team was established in Orthopedic Department of West China Hospital based on project management theory in January 2016. Psychology and sleep,nutrition, rehabilitation and other 10 project management teams in total were constructed after strict nursing team training, and nursing personnel training was carried out. Using convenience sampling method,50 nursing staff working in spinal orthopedic department from April to December 2015 were recruited in control group,and 50 nursing staff working from April to December 2016 were recruited in experimental group. On the basis of traditional training mode which was applied in control group,experimental group focused on the project sub-specialty,and then consciously carried out the personnel training work. Compare evaluation of nurses before and after the project management. At the same time,a convenience sampling method was adopted to investigate the satisfaction of 100 discharging patients. Results The understanding of project definition,nursing capacity,nursing work efficiency,patients and their families′ respect for nursing work,nursing research capacity and teamwork ability of experimental group were significantly lower than the control group (P< 0.05). Patient satisfaction improved after carrying out the project management,and the difference was statistical significant (P=0.013). Conclusions The project management theory provides a theoretical basis for nursing personnel training,which has important guiding significance for the training of clinical nursing personnel.

OBJECTIVETo observe the changes in expression of microRNA-203 and P63 in human epidermal stem cells and KCs, and to investigate their effects and significance in the epidermal proliferation and differentiation.

METHODS(1) Five normal foreskin tissue specimens were collected from 5 patients by circumcision in Department of Urinary Surgery of the First Affiliated Hospital of Nanchang University from March to June in 2013. Then single cell suspension was obtained by separating epidermis with trypsin digestion method. The cells were divided into quick adherent cells and non-quick adherent cells by type IV collagen differential adherent method. The biological characteristics of cells were observed by inverted phase contrast microscope immediately after isolation and on post culture day (PCD) 3. The expression of CD29, keratin 19, keratin 1, and keratin 10 was identified by immunocytochemical staining. The expression of microRNA-203 and mRNA of P63 was determined by real-time fluorescent quantitative RT-PCR. The protein expression of P63 was determined by Western blotting. Data were processed with t test and Pearson correlation analysis.

RESULTS(1) Immediately after isolation, quick adherent cells were small, round, and dispersed uniformly. On PCD 3, the cells adhered firmly, and they grew in clones. Immediately after isolation, non-quick adherent cells appeared in different shapes and sizes, and dispersed unevenly. On PCD 3, the cells adhered precariously and did not show clonal growth. Quick adherent cells showed positive expression of CD29 and keratin 19, while non-quick adherent cells showed positive expression of keratin 1 and keratin 10. Quick adherent cells were identified as epidermal stem cells, and non-quick adherent cells were identified as KCs. (2)The expression level of microRNA-203 in epidermal stem cells (0.74 ± 0.20) was lower than that in KCs (3.66 ± 0.34, t =16.582, P <0.001). The mRNA expression level of P63 in epidermal stem cells (4. 16 ± 0.28) was higher than that in KCs (2.90 ± 0.39, t =5. 850, P =0.001). The protein expression level of P63 in epidermal stem cells (1.42 ± 0.05) was higher than that in KCs (0.73 ± 0.03, t =26.460, P <0. 001). (3) The expression level of microRNA-203 was in significantly negative correlation with the expression levels of mRNA and protein of P63 (with r values respectively - 0. 94 and -0.98 , P values below 0.05).

CONCLUSIONSThe expression levels of microRNA-203 and P63 in human epidermal stem cells and KCs were significantly different, which might be related to the different characteristics of proliferation and differentiation of the cells.
