1.Research on AQP4 and central nervous system diseases
International Journal of Pediatrics 2013;40(6):607-610
Aquaporins (AQP) are membrane channel proteins which facilitate water transport through cell membranes.AQP4 is abundantly expressed in brain which is located in endfeet of astrocytes adjacent to capillaries,neurons,and neuronal synapses.It has also been identified in neurons of the supraoptic and paraventricular nuclei of the hypothalamus.AQP are closely related to many central nervous system diseases.Researches have showed that AQP4 participates in regulating and controling process of cerebral edema that caused by brain trauma,cerebral ischemia,intracranial infection and mmour,etc.AQP4 antibody is specific biological markers in serum of patients with neuromyelitis,which helps diagnosis of neuromyelitis optica and multiple sclerosis,predicting prognosis and therapy of neuromyelitis optica.AQP4 has been shown to play roles in pathological and physiological process of neurodegenerative diseases,epilepsy,migraine.This article aims to review the distribution,function,influential factors of AQP4 and research development of AQP4 in common diseases of the central nervous system.

Gene chip technology is a large amount of information,simple operation,fast speed of the nucleic acid sequence determination and quantitative analysis technique.The advantages of this technology include high integration and high content of micromation,parallelism,diversification and automatization.Currently,gene chip technology is increasingly being used in clinic,including disease diagnosis,treatment guidelines and prognosis.The progresses of the diagnosis of the gene chip technology in unexplained mental retardation are summarized in this paper.
3.Progress of dendritic spines in the nervous system diseases
International Journal of Pediatrics 2013;(3):287-289
Dendritic spines are functional protrusions on neuron dendrites and formation of excitatory synaptic sites.Dendritic spines contain a variety of cell surface receptors,actin cytoskeleton,scaffolding proteins and other components,which regulate the growth of dendritic spines maturation and structure.Multiple components within dendritic spines not only have effects on expression of its shape and structure,but also on the function.Morphology of dendritic spines is closely related with its function.Its shape is affected by many factors in the changing process.So dendritic spine plasticity is an important aspect of synaptic function in the central nervous system,and is closely related with learning and memory function and central nervous system diseases.
4.Influence of individualized nursing intervention on success rate of holding breathing in patients undergoing dual-source CT imaging
Chinese Journal of Practical Nursing 2011;27(25):41-42
ObjectiveTo discuss the infiuence of personalized nursing intervention on success rate of holding breathing in patients undergoing dual-source CT imaging.Methods167 cases of patients were randomly divided into the observation group(100 cases)and the control group(67 cases). The control group implemented routine care, on the basis of routine care, the observation group was given pertinent and individualized nursing intervemion according to the factors causing failure of holding breathing, including better psychological counseling for patients, the right guidance, to alleviate symptoms, to improve comfort degree, to give clinical evaluation after inspection, et al.ResultsThe success rate of holding breathing in the observation group and the control group was 99.0% and 88.1%, the observation group was significantly higher than the control group.ConclusionsHealth education for patients, attention to patients' illness, mental state, cognitive and behavioral changes in a timely manner to give individualized nursing intervention and seriously check the implementation of results in patients, can effectively improve the success rate of holding breathing in patients undergoing dual-source CT coronary angiography.
5.Ventilation strategies during and after cardiopulmonary resuscitation in children
Chinese Pediatric Emergency Medicine 2012;19(1):5-8
During cardiopulmonary resuscitation (CPR),ventilation is provided by either mouth-to-mouth or bag-mask technique,and give 12 to 20 times breaths per minute.Ventilation should deliver 8 to 10 times breaths per minute after endotracheal intubation.Compression-ventilation ratio is 30∶2 for one rescuerand 15∶2 for two rescuers.After the return of spontaneous circulation,if no spontaneous breathing or irregular,respiratory insufficiency,mechanical ventilation is required.High oxygen and excessive ventilation after CPR should be avoided.When acute lung injury or acute respiratory distress syndrome occurs after CPR,lung protective ventilation strategy is applicable.
6.Clinical effectiveness of hyperbaric oxygenation on patients with chronic hepatitis
Chinese Journal of Physical Medicine and Rehabilitation 2003;0(06):-
Objective To observe the effects of hyperbaric oxggenation (HBO) on liver blood flow, hepatic functions and the changes of clinical manifestations in patients with chronic hepatitis. Methods Thirty two patients with chronic hepatitis (HBO group) were treated with HBOThe changes of blood flow of the right branch of portal veinin HBO group were and hepatic functions were measured. Results After HBO, hepatic functions were significantly improved, and the blood flow of the right branch of portal veinwas was increased as compared with that before the treatment(0.318?0.101 L/min vs 0.378?0.102 L/min, P
7.Comparison of efficacy and safety between gatifloxacin and levofloxacin in treatment of patients with light to moderate acute lower respiratory tract infections
Chinese Journal of Clinical Pharmacology and Therapeutics 1999;0(04):-
0.05 ), bacterial clearance were 100% and 90%, and adverse reaction rates were 10%(2/20)and 10.53 % ( 2/19 ), respectively. All those adverse reactions were mainly gastrointestinal tract reactions. The abnormality of laboratory inspections associated with trial drugs happened to 4 and 5 patients in two groups. The reactions were mostly light increase of aminotransferase without effect on therapy. CONCLUSION: Gatifloxacin is an antibiotic with large antimicrobial spectrum and can be recommended to treat light to moderate acute lower respiratory tract infections.
8.The essential cause resulting in "high personal medical expenditure":Decreasing Finance for Health Care from the Government
Chinese Medical Ethics 1996;0(01):-
With the development of income per capita,"high personal medical expenditure" shows the wider of disease risk,which is resulted from the increasing medical payment and imperfect risk pooling.The former that is related with the excess delivery of advance medical technology and drug has been a dominating reason since 1980.And the imperfect risk pooling means the imperfect social medical insurance,of which the government should take charge.However,influenced by the reform policies of the economic systems,similar to all the transitional economies reducing the government role in healthcare financing,China has put an increasing emphasis on the payroll tax-based social insurance system and out-pockets payment,moving away from a predominantly general revenue-based financing system under the old command economy.In a conclusion,the Chinese Government should make clear the financing function,and replace fee-for-service(FFS) payment according to the distorted pricing system with aggregated pre-payment for patients covered by social insurance to mitigate the incentive for cost escalation.Meanwhile,the target of the new medical reform that should resolve the problem of high personal medical expenditure is demanding and perfecting the social medical insurance with wider risk pooling.
