Objective Toinvestigate the effect ofPBLmethod in the pediatrics'nurse teaching.Methods PBL teaching was practiced in trial group,while LBL teaching was practiced in control group.The writers made an analysis of this teaching by way of questionnaire and exam.Results Many students by PBL teaching accept PBL teaching,and improve their self-study ability,understanding ability,analyzing ability and so on.Conclusion PBL teaching method can effectively promote both the teaching quality in pediatric nursing and the students'study interest.

It is now popularized that the multi-media and network technology are applied in the field of college English teaching.This essay discusses the characteristics of multi-media network auxiliary English teaching and the cultivation of independent learning ability.

Asthma is the most common chronic respiratory disease in children. Currently,inhaled corti-costeroids is the most effective drug for asthma,however,there are some adverse effect by long-time using. Ac-cording to recent literature,long-time treatment with inhaled corticosteroids may inhibit height growth. But this suppression only occurs within early stage of asthma treatment, and have no effect or slight effect on adult height. The adverse effects of inhaled corticosteroids for height are also related to its iypes,dose and usage.

Parkinson disease (PD) is a common neurodegenerative disease,of which clinical symptoms give priority to movement disorders,accompanied by a series of non-motor symptoms,such as pain.Studies suggest that 40％ to 85％ of PD patients combined with pain,of more nature is related to muscleskeletal and dystonia.PD combined with pain severely reduces the quality of life of patients.However,it is still lack of uniform clinical evaluation and effective treatment.This paper makes a brief overview about the status and research progress of the evaluation and treatment of PD combined with pain.

Objective:To study the characteristic of energy metabolism in moderate and severe OSA before and after CPAP. Methods:The REE was measured before and after 5-8 week treatment by CPAP in OSA patients. Health staff of single obesity in the hospital were as control. Results:During sleep, the enengy-metabolism was increased significantly in OSA patients. After treatment by CPAP, it was decreased (P

Objective: To explore change of heart rate turbulence (HRT) in patients with coronary artery disease (CAD) and its predictive value. Methods: A total of 58 CAD patients were regard as CAD group. The 50 normal persons with negative CAG were regard as normal control group. All subjects received 24h dynamic ECG, CAG and echocardiography examination. Left ventricular ejection fraction (LVEF) and HRT indexes were compared between two groups. Results: Compared with normal control group, there was significant rise in turbulence onset [TO, (-1.34±1.09)% vs. (2.32±0.60)%] and significant reduction in turbulence slope [TS, (11.14±2.27) ms/RR vs. (3.44±0.60)ms/RR] in CAD group, P<0.01 both; in CAD group, along with coronary artery lesion aggravated (single-, double-, multi-vessel coronary disease), there was significant rise in TO [(1.35±0.52)% vs. (2.56±0.83)% vs. (3.01±1.62)%] and significant reduction in TS [(6.49±1.79) ms/RR vs. (3.33±1.02) ms/RR vs. (1.66±0.30) ms/RR], the difference was significant in two-two comparison among all groups, P<0.05 or <0.01; compared with CAD without cardiac event group, there was significant rise in TO [(1.68±0.61)% vs. (2.24±0.24)%], and significant reduction in TS [(5.87±1.22) ms/RR vs. (1.65±0.23) ms/RR] and LVEF[(66.18±2.64)% vs. (56.36±3.34)%] in CAD with cardiac event group, P<0.01 all. Conclusion: Weakened HRT phenomenon exists in CAD patients. HRT can be treated as an index evaluating severity of CAD patients’ condition and an effective predicting index for recurrent cardiac events in CAD patients.

Objective To assess the value of ultrasoud examination with transvaginal scaning(TVS) in the diagnosis of tubal pregnancy(TP). Methods 40 cases of clinically suspected TP were exeamined by two ultrasoud approaches: transvaginal and transabdominal prior to surgery.Based on surgery and pathology ,the sonographic manefestutions and diagonostic results of both methods were compared and analized statisticlly. Results The TP masses were visualized in 36 cases in TVS group(36/40) as compared with 27 cases in TAS group (27/40) (? 2=7.364, P

M channel, a voltage-dependent potassium channel, has been found in a variety of neurons. It is activated near the threshold of neuron action potential,producing a primary K~+ current, namely the M-current. The M-current can be modulated by many neurotransmitters and hormones, which can influence neuron excitability, conduction and neurotransmitter release. This review discusses the signal transduction pathway from G_~ q/11 activation to intracellular calcium, membrane phospholipid and phosphokinase, and explains the mechanism of M-current modulation by neurotransmitters.
