Objective If IL-2 and IFN-? are united,perhaps we may see a more significant antitumor effect.A fusion gene of IL-2 and IFN-? was designed and constructed by DNA engineering.Methods CEA promotor、IL-2cDNA and IFN-?cDNA were obtained by PCR and RT-PCR.SDS-PAGE was used to examine the results;pcDNA-IL-2、pcDNA-IFN-?、pCEA-IL-2/ IFN-?、pEGFP-IL-2/ IFN-? were transfected to CEA high expression cell line(Lovo)by use of liposome.The fusion protein expression was examined by fluorescence microscope and Western blotting.Results IL-2/ IFN-? fusion gene can be expressed in tumor cells.Its expression is more obvious in CEA high expressed cells(Lovo),and can be located in cell plasma.Conclusion The fusion gene can be expressed in plasma of CEA high expressed cell lines.It may have a new anti-tumor effects.

Orthodontic tooth movement (OTM) is a very complicate mechano-biological procedure which is accomplished by the remodeling of periodontal tissues via orthodontic force.As the connective tissue between alveolar bone and cementum,periodontal ligament plays a vital role in the response and conduction of orthodontic force.The susceptible response of periodontal ligament to orthodontic force during OTM is a critical factor on inducing and modulating periodontal tissue restitution.This article reviews the concrete role of periodontal ligament and its mechano-biological behavior during OTM,discusses its mechanical response and biological mechanism respectively on histological,cellular and moleucular levels.

Objective:To investigate the clinical efficacy of loratadine combined with compositus mentholi cream in the treatment of infantile with external ear eczema and evaluate the safety .Methods:Totally 96 cases of infantile with external ear eczema were ran-domly divided into the observation group (n=48) and the control group (n=48) according to a random number table .Both groups were given the conventional treatment .The control group was treated with topical compositus mentholi cream , while the observation group was treated with loratadine additionally .Both groups were treated for 10 d.The clinical efficacy , the level changes of interleukin-4 (IL-4), interferon-γ(IFN-γ) and immunoglobulin-E (IgE) before and after the treatment, the incidence of adverse reactions during the treatment and the relapse after 6-month follow-up were compared between the groups .Results:The total effective rate of the obser-vation group (95.83%) was significantly higher than that of the control group (79.17%, P<0.05); the levels of IL-4, IFN-γand IgE in both groups were significantly decreased after the treatment (P<0.05), and those in the observation group were significantly lower than those in the control group (P<0.05);there was no significant difference in the incidence of adverse reactions between the groups (P<0.05); the recurrence rate in the observation group (8.33%) was significantly lower than that in the control group (22.92%, P<0.05).Conclusion:The clinical efficacy of loratadine combined with compositus mentholi cream in the treatment of infantile with external ear eczema is reliable with promising safety .

Reading therapy in hospital libraries, academic libraries and public libraries was described in terms of its theoretical study and practical study,and its significance in hospital library was elaborated by comparative analysis.

The WeChat service provided at present in 14 hospitals directly under the Yunnan Health and Family Planning Commission was surveyed with suggestions proposed for providing active Wechat service in hospitals in order to alleviate the difficulty to see a doctor and the tense relationship between doctors and patients.

Objective To analyze the mechanism of hemiparalysis children,cerebral vessels' physiological feature of children, pathological change and therapeutic efficacy after light craniocerebral trauma. Methods To analyze clinical manifestation,imageology data,therapy and therapeutic efficacy of 32 hemiparalysis children patients after light craniocerebral trauma. Results Mon-basal ganglia cerebrel infarction was discovered in all children,and cure rate of broadening blood vessel therapy was 84% in a week after trauma. Conclusion Blood vessel spasm and thrombosis happened after light craniocerebral trauma to artery of cerebral hemorrhage that erupt perpendicularly from arteria cerebri media and had incomplete tunica intima development. Nonage broadening blood vessel therapy could gain well curative effect.

Nitric oxide (NO) is a vascular endothelium-derived relaxing factor.NO inhalation therapy is widely used in the field of neonatology.When NO acts as selective pulmonary vasodilation,it can reduce pulmonary arterial pressure and improve oxygenation.When NO serves as a major regulator of cerebral vasomotor factor,it may have physiological and pathological impact in cerebral ischemia-reperfusion injury.So NO has a wide range of applications in persistent pulmonary hypertension of the newborn,bronchopulmonary dysplasia,hypoxia ischemic encephalopathy.With the recently in-depth study of NO,its biological role has more and more clinical attention in the field of neonatology and has broad valid prospects.However,NO has some side effects which still have some controversial aspects of the application in premature,especially in very low birth weight children.The article focused on the mechanism and clinical applications of NO in the neonatal disease.

To explore the stability of impact assay for determination of microorganism in indoor air, the comparisons of continued sampling times of 2-minute and 4-minute for monitoring on microorganism of indoor air were carried out with JWL- Ⅱ B multifunctiom air microorganison monitor in 11 hotels, public places of entertainment, barbar shops and beauty shops. The results showed that, under a same environmental condition, there was no significant differences between the data obtained by 2-minute monitoring and 4-minute monitoring (t=1.854, P＞0.05).It indicated that impact assay presented very good stability in detecting the microorganism of indoor air within certaindetecting duration.

ObjectiveTo explore the effect of different nursing models to improve the quality of sleep for elderly patients in department of cardiology.Methods240 cases of patients in department of cardiology in our hospital were randomly divided into the control group and the observation group with 120 patients in each group.The control group was given conventional medical care and the sleep-related health education.While the observation group was given the targeted intervention measures based on the control group,including the provision of good psychological care measures to ensure a good sleep environment,arrange a reasonable sleep time,increase bedtime benign behavior and scientific education of hypnotic drugs knowledge.The PSQI score and sleep quality of different time points were compared.ResultsThe PSQI score of the observation group 1 week and 2 weeks after admission was significantly decreased compared with that upon admission,and was better than those of the control group.The PSQI score of the control group 2 weeks after admission had a marked decline,but the PSQI score 1 week after admission showed no significant difference.In the aspect of sleep quality,the rate of good sleep quality for the observation group 1 week and 2 weeks after admission increased significantly compared with that upon admission.The rate of the quality of good sleep 2 weeks after admission for the control group improved significantly than admission.The rate of promotion for the observation group was obviously better than that of the control group.ConclusionsThe targeted quality of sleep and psychological care interventions for elderly patients in department of cardiology can significantly improve the sleep quality in patients after admission,and enhance their confidence in overcoming the disease,thus contribute to disease treatment and rehabilitation.

Objective To understand cerebral edema and development procedure of different time windows.Methods To analyze their prognosis through image document and operation findings of 52 cerebral trauma patients which were confirmed cerebral edema by CT and operation.Results he light cerebral oedema patients have a better prognosis,10 patients died and 1 patient became a plant man in 11 malignant brain dilatation patients.Conclusion The infernal circle of high brain pressure-cerebral ischemia,cerebral anoxia-cerebral edema result in cerebral edema-brain dilatation-malignant brain dilatation after cerebral trauma which leads to unremitting aggravated pathogenefic condition.So effective means should be used to interrupt the unremitting heightening ICP.
