a-conotoxin is a kind of marine neurotoxins. It has a particular chemical structure and can bind specificilly to acetylcholine receptor. This article deals with the types, structural characters,biological activities and preparation methods of a-conotoxin and briefly introduces potential applications in the aspects of biochemistry, biology and new drugs research.

Objective To investigate the early neurotoxicity of rotenone on dopaminergic neurons and explore an ideal tissue model. Methods A long-term midbrain slice culture system of SD pup was established according to the interface tissue culture method.After rotenone was added for some time,its toxic effects on the whole slices and the dopaminergic neurons were identified through the measurements of lactate dehydrogenase(LDH) released into the medium from the slices and dopamine(DA) content from the cultured tissue,as well as the observations of immunohistochemistry for tyrosine hydroxylase(TH). Results In those cultures exposed to rotenone for 24 h,the level of DA in tissue dramatically decreased with the concentrations rising.The processes of TH-positive neurons in slices demonstrated some morphological changes,such as appearance of string of beads,reduce of numbers and even disappearance.The content of dopamine in tissue was dominantly decreased with 5 nmol/L rotenone for 14 days,although its cellular morphology was not seen to change.Conclusion Long-time stable midbrain slice culture system has been set up successfully.The neurotoxicity of rotenone on the whole slices and dopaminergic neurons shows a dose-dependent manner.The functional damages on the neurons may be earlier than their morphological changes,of which the injury in the processes of neurons seems to be an early characteristic.

Objective:To explore the influencing factors of physicians' professionalism,to understand the cognitive status and changes of professional responsibility and put forward the corresponding strategy.Methods:The satisfaction and cognitive status of physicians'professionalism were investigated using the self-designed questionnaire that adapted to medical staff,and the data was analyzed using statistical software SPSS19.0.Results:It showed that the satisfaction with the job itself was quite high.But they thought that the work risk was high,their own value was difficult to realized,and the professionalism was lack of cultivation.Conclusions:It suggests to put forward measures and suggestions from the perspective of system reform,vocational education,hospital culture,social atmosphere,decision-making of doctors and patients together.

Objective Investigate the effect of substance P and receptor antagonist on the current of NCX in ASMC.Methods Primary rat ASMC cultures were established.Immunofluorescence was used to identify ASMCs.Patch clamp exam was used to assess NCX currents in ASMC before and after intervented by Ach,substance P,NK-1R receptor antagonist and nimodiping,Voltage-current curves were drawn according to variation of voltage and current.PA indicates current amplitude,PF indicates cell area,and PA/PF indicates current density.Results As the voltage increased,the current density increased.When voltage up to-40mV the reverse current appeard.When the voltage is 60mV the current density in the Ach intervention group was highest,but lowest in the nimodipine intervention group;the current density in the substance P intervention group is more than in control group but lower than in Ach interevention group.The current density in the substance P receptor antagonist intervention group higher than nimodipine interevention goup,but lower than the other group (P ＜0.05).Conclusion In asthma airways,Ca2 + overload is related to the appearance of reverse-mode NCX.NK-1R antagonist plays a role in decreasing the Ca2 + concentration,which can relieve the current of reverse-mode NCX,and may benefit alleviating airway inflammation and responsiveness.As a result,NK-1R antagonist may be an attractive target for therapeutic approaches to asthma.

Sleep apnea includes obstructive sleep apnea,central sleep apnea and mixed sleep apnea.Ob-structive sleep apnoea syndrome(OSAS)is affecting up to 5.7% of children,which hss adverse impact on growth,development cognitive and behavioral outcomes,and untreated OSAS increases cardiovascular risk,so paying closer attention to childhood OSAS early diagnosis and treatment seems more important.First-line treat-ment in OSAS children is adenotonsillectomy,although other treatment options available include continuous posi-tive airways pressure,anti-inflammatory therapies,airway adjuncts and orthodontic appliances.Central sleep ap-nea may be related to respiratory regulation center immaturity or dysplasia.Central sleep apnea may be hereditary or acquired.Therefore,the treatment of central sleep apnea should be focused on primariy etiology.

Objective To investigate the effect of neuropeptide substance P on airway smooth muscle cell contraction amplitude.Methods According to random method, 10 Wistar rats were divided into normal group and asthmatic group.By inhaled OVA to make asthmatic rat model;primary culture ASMC;confocal microscopy were used to observe the morphological changes and measure the length before and after different intervention.The percent of contraction length come from different group ASMC were used for statistical analysis.Results The ASMCs volume in acetylcholine intervented group and substance P intervented group decreased significantly,cell diameters shorten, cytoplasm reduction and cell arranged densely.The ASMCs volume in substance P receptor antagonist intervented group and nimodipine intervented group are about the same size as the ones in normal control group, were spindle-shaped, abundant cytoplasm and arrangement regularly.The contraction length percent of Ach intervened group is the biggest(19.60 ± 3.47) ％, contraction length percent of nimodiping intervented group is the shortest(3.25 ± 1.14)％ ,the contraction length percent in substance Precepter antagonist intervented group is bigger than the one in control group (3.54 ± 1.26) ％, but less than the one in Ach intervented group, asthmatic (14.36 ± 2.37) ％ and substance P intervened group (17.79 ± 3.19) ％.Conclusion Substance P can increase the amplitude of airway smooth muscle cell contraction, but the effect less than Ach;substance P receptor antagonists can inhibit smooth muscle cell contractility, but the effect less than nimodipine.Substance P participates in acute attack of asthma, increases airway reactivity by increasing airway smooth muscle contraction intensity.

Objective To investigate the effect of budesonide on NK-1 receptor expression in airway smooth muscle cell (ASMC). Methods According to the random method,45 wistar rats were divided into three groups: asthmatic group, budesonide treatment group and control group. Aerosolize ovalbumin was used to make asthmatic rat model. Budesonide treatment group were given budesonide after inhaled ovalbumin. On day 21 .primary rat ASMC culture was conducted. The fourth cell passage and purified ASMC was collected for RT-PCR. The content of NK-1R was determined by real-time quantitative PCR. Data were expressed as mean±standard error (SE). The ANOVE Tukey test was carried out by using SPSS17.0 software and P＜0. 05 was considered significant. Results As compared with that of asthmatic group(1.1687±0.1356),NK-1R mRNA in therapy group( 1.0820 ±0. 1146) decreased significantly (P ＜0.05) ,but remained still higher than that of control group(1.034 7±0.2503) (P＜0. 05). Conclusion NK-1R may be involved in the pathogenesis of asthma. Budesonide may down-regulate the expression of the NK-1R mRNA in the airway smooth muscle cell, which may inhibit inflammation in asthmatic attacks.
