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.

Objective In this article, the mode change and features of knowledge service of TCM professional library in the creation times were expounded. Knowledge service is the main trend of library service in the 21 century. As a professional TCM library, we have made attempts on providing omnibearing knowledge service of medicine, scientific research, teaching and clinical practice for our readers.

Current treatment strategies for recurrent or metastatic head and neck squamous cell carcino-ma(HNSCC)include palliative chemotherapy and anti-EGFR targeted agents.Angiogenesis is crucial both for the growth of a primary tumor and the development of distant metastasis.Therefore,the angiogenesis factors and their receptors become the targets of therapeutic agents.Current anti-angiogenesis drugs achieve the purpose of treatment mainly by blocking VEGF-VEGFR pathways.And it gets certain effects in clinical trials for the treat-ment of HNSCC.Anti-angiogenesis therapy will provide more choices for treating HNSCC.

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 study the effect of acupuncture Zusanli on brain functional magnetic resonance imaging.Methods 96 healthy volunteers were randomly divided into acupoint group and non-acupoint group.The acupoint group received acupuncture Zusanli,and the non-acupoint group received manipulation,acupuncture and sham acupuncture.The functional brain imaging was determined by MRI,the brain functional images were compared between two groups.Results All subjects were matched with the end of the experiment,the acupoint group received acupoint stimulation,had obvious needling sensation,the non-acupoint group had mild needling sensation.The acupoint group activated 13 brain regions,non-acupoint group in 10 brain regions,the thalamus,pons,supramarginal gyrus in non-acupoint group without the activation.In the basal ganglia (28 cases vs.5cases) and temporal lobe (38cases vs.21cases) between the two groups were activated,the difference was statistically significant(x2 =36.250,P ＜ 0.05).In the temporal lobe,the left hemisphere response rate(73.68％) was significantly higher than the right hemisphere (36.84％),the difference was statistically significant (x2 =8.265,P ＜ 0.05).In the basal ganglia,left hemisphere activation (67.86％) was higher than that of the right hemisphere(42.86％),but the difference was not statistically significant (x2 =0.724,P ＞ 0.05).Conclusion The research of acupuncture by brain functional magnetic resonance imaging showed that Zusanli acupoint can activate the brain function area through brain regulation and treatment of body organs,so as to prove the existence of its own and meridian sensing characteristics.

Objective To investigate the effect of acupoint injection of Xingnaojing injection on the intelligence development and hemorheology in children with mental retarded cerebral palsy.Methods Sixty patients with cerebral palsy complicated with mental retardation were selected from March 2015 to January 2017 in Anyang Maternal and Child Health Care Hospital.The patients were divided into observation group and control group according to the treatment methods,thirty cases in each group.The patients in the control group were treated with routine treatment and rehabilitation training;based on these,the patients in the observation group were treated with acupoint injection of Xingnaojing injection.The developmental quotient (DQ) was calculated by the children's neuropsychological development scale.The therapeutic effects,intelligence and haemorheology improvement of patients in the two groups were evaluated.Results There was no significant difference in DQ score between the two groups before treatment (t =0.545,P ＞ 0.05).The DQ score after treatment was significantly higher than that before treatment in the two groups (t =9.386,10.057;P ＜ 0.05).The DQ score in the observation group was significantly higher than that in the control group after treatment (t =3.641,P ＜ 0.05).There was no significant difference in hemorheological indexes between the two groups before treatment (P ＞ 0.05).The high shear whole blood viscosity,low shear whole blood viscosity,plasma viscosity,hematocrit,platelet adhesion rate and fibrinogen level after treatment were significantly lower than those before treatment in the two groups (P ＜ 0.05).The high shear whole blood viscosity,low shear whole blood viscosity,plasma viscosity,hematocrit,platelet adhesion rate and fibrinogen level in the observation group were significantly lower than those in the control group after treatment (P ＜ 0.05).The total effective rate in the control group and observation group was 66.67％ (20/30) and 90.00％ (27/30) respectively,the total effective rate in the observation group was significantly higher than that in the control group (x2 =4.812,P ＜ 0.05).Conclusion Acupoint injection of Xingnaojing injection can significantly improve the intelligence,hemorheology and therapeutic effect in children with cerebral palsy complicated with mental retardation.
