0.05). Conclusions The LTs synthesis is elevated in RSV bronchiolitis and LTs may participate in the pathogenesis of RSV bronchiolitis. Leukotriene receptor antagonist may play an important role in RSV bronchiolitis. However there still needs further research on the relationship between LTs and eosinophils count in the pathogenesis of RSV bronchiolitis.

Polyamidoamine (PAMAM) dendrimers is considered a better genetic carrier for its ability to form with DNA a nano-sized polyelectrolyte complex of high stability and dissolubility. The mechanism of PAMAMmediated gene endocytosis has been fairly clear and the researches in vitro have confirmed that PAMAM had high transfection efficiency and low cytotoxicity. The researches in vivo have further confirmed that PAMAM had a potential application foreground in the field of gene therapy including in the prevention and treatment of ewing's sarcoma and pulmonary fibrosis, in heart transplantation, and in the preparation of falciparum malaria vaccine.

Objectives To evaluate the application of systemic octreotide radioactive imaging in diagnosis and follow-up for children with neruoblastoma (NB). Methods Clinical data of 14 children with NB applied systemic octreotide radioac-tive imaging from April 2006 to March 2011 were collected and analyzed. For the ifrst-visit patients, they were applied with systemic octreotide radioactive imaging at the ifrst follow-up appointment after routine treatment. And for recurrent or sus-pected recurrent cases, systemic octreotide radioactive imaging was applied before the treatment and after 2-3 weeks chemo-therapy. Results Nine of 14 patients were male and 5 were female with a median age of 4.8 years (1-10 years). According to In-ternational Neuroblastoma Staging System (INSS), 4 cases were categorized as stage 3 and 10 cases were categorized as stage 4. The uptake rate of systemic octreotide radioactive imaging in primary site or metastasis sites of 8 cases were higher than nor-mal site with positive rate of 57.14%(8/14). One case was conifrmed as false positive by treatment and imaging examination. Six cases were negative in primary site or metastasis sites with negative rate of 42.86%(6/14). One case was conifrmed as false negative via treatment and imaging examination. Therefore, the sensitivity of systemic octreotide radioactive imaging reached 85.71%(12/14). Conclusion Systemic octreotide radioactive imaging could be one of the effective methods for NB in diagno-sis, follow-up and evaluation of prognosis.

With the development of minimally invasive surgery,great developments have been made in laparoscopie techniques and digestive endoscopy.However,laparoscopy may cause injury by abdominal puncture,and digestive endoscopy is a painful examination for patients and is difficult to localize the tumor.Magnetic anchor makes use of magnetic attraction in positioning,and it improves laparoscopy and endoscopy by external magnetic field or magnetic handle.Nowadays,combined application of magnetic anchor and laparoscope and endoscope in the treatment of digestive diseases has been accepted by many medical centers,and further researches need to be carried out to realize the aim(small trauma,little pain and quick recovery)of minimally invasive surgery.

Papers on mycorrhizas were searched from SCI (Science Citation Index) database. In order to understand the research progress of mycorrhizas in China, the paper on mycorrhizas from 1989 to 2007 was analyzed with method of bibliometrics. Mycorrhizal researches showed an increasing tendency during 1989 to 2007, while the increase was obviously accelerated after 2000. Only 5.22% of the articles were published in journals with impact factor above 5, indicates that the academic levels of researches need being enhanced. Currently the research on mycorrhizas was mainly focused on Arbuscular mycorrhiza (AM), especially on effects of mycorrhizal fungi on plant physiology, effects of mycorrhizal fungi on resistance of host plants, Mycorrhizal diversity community and ecological distribution, and phytoremediation with Mycorrhizal plants. The future research should emphasize in phytoremediation with Mycorrhizal plants and identification of fungal species with molecular biological technology.

Objective:To evaluate the effect and safety of penehyrclidine hydrochloride when it was applied preoperatively in outpatient.Method:240 patients were randomly divided into two groups.Group P(120 cases)was treated with penehyclidine hydrochloride 0.5mg before the anesthesia as Group A(120 cases)with Atropine 0.25 mg.Sedation scale was observed just 5 and 15 minutes after drug administration.Analge scale,the degree of the patient's dry-mouth and PONV were also recorded.Time of recovery and leaving were studied too.Result:Group P had significantly better analgesic efficacy than Group A(P0.05).The degree of the patients dry-mouth were statistical difference between 2 group both 15min and 4h postoperation(P

Thyroid nodules are very common.Its etiological factors include hyperplasia,adenomas,cancer,cysts,and thyroiditis.Most of thyroid nodules are benign.The management of thyroid nodules whether thyroidectomy or observation is according to their nature.So,the key of the therapy is to identify that they are benign or malignant.We should comprehensive evaluate patients' history,physical examination,laboratory examination,and auxiliary examination for judging the nature of thyroid nodules and making decision in the choose of thyroidectomy or observation.

Objective To construct a yeast expression vector containing human TIP60? gene (a spliced form of HIV-1 tat interactive protein,HTATIP,60?103) and screen its interaction proteins by yeast two-hybrid. Methods Human TIP60? gene fragment was amplified by RT-PCR and cloned into pGBKT7 vector. Using TIP60? as bait,the proteins interacting with TIP60? were screened from a human liver cDNA library. The positive clones were analyzed by bioinformatic methods. Results Human TIP60? cDNA was successfully amplified and cloned into the pGBKT7 vector and indentified by double enzyme digestion and DNA sequencing. Using yeast two-hybrid,32 clones were screened from a human liver cDNA library,and 9 positive clones including histone deacetylase 7A (HDAC7A),mouse double minute 2 (DMD2),B-cell CLL/lymphoma 3 (BCL3),endothelin receptor type A (EDNRA),androgen receptor (AR),PHD finger protein 17 (PHF17),Ataxia Telangiectasia Mutated (ATM),CAMP responsive element binding protein 1 (CREB1),orphan steroid receptor BD73 were verified after sequencing. Conclusion The screened interaction proteins with TIP60? by yeast two-hybrid may be involved in the roles of transcriptional regulation of TIP60?.

Objective: To deeply investigate the influential factors of mental health in medical students by structural equation modeling.Methods: 480 medical students were tested with SCL-90,adolescent self-rating life events check list and simplified coping style questionnaire,then theoretical model were established and confirmed for the relationships of life events,satisfaction degree with their profession,coping styles and mental health.Results: Study stress,human relations,satisfaction degree towards their profession and coping styles closely correlated with mental health status,and the structural equation modeling fitted the data very well,GFI and AGFI were both larger than 0.90.Conclusion: Use of structural equation modeling has more advantages than the traditional statistical methods,but it should combine with professional knowledge when it is used.
