Alzheimer's disease(AD),which is one type of senile deimentia, has three remarkable pathologic characteristics-senile plaque,neurofibrillar tangles and neuronal death. As a neurotrophic factor, basic fibroblast growth factor(bFGF)is closely related to AD. This article reviewed the interaction between bFGF and AD-associated gene products(such as amyliod ? protein,presenilin, apoloprotein E and microtubulin associated protein tau)and neuronal apoptosis. Some researchers suggested that bFGF may be put forward as potential therapeutic agent in AD and play a role in preventing or retarding the pathological process of this disease, alleviating or even eradicating the pathological insults of this disease.

Objective To investigate the analysis of Symbicort in stable stage of chronic obstructive pulmonary disease treatment and intervention. Methods 80 patients with chronic obstructive pulmonary disease in stable period from June 2014-2016 year in May in our hospital were randomly divided into control group and experimental group, 40 cases in each group. The control group of patients with the use of simple Symbicort treatment and routine nursing care to patients, patients in the experimental group using Symbicort combined with Bailing Capsule for treatment, and the implementation of targeted nursing intervention measures, compare the effect of two groups of patients and nursing satisfaction. Results the clinical treatment of patients in the experimental group the total efficiency 95.0%, nursing satisfaction was 97.5%, the control of clinical patients in the treatment group the total effective rate was 80.0%, nursing satisfaction was 87.5%, the experimental group was significantly higher than the control group, the difference was statistically significant (P<0.05). Conclusion Chronic In the stable period of obstructive pulmonary disease, the combination of Xin Yi capsule combined with Bailing capsule can effectively improve the pulmonary function of patients and improve the clinical therapeutic effect, and is worthy of popularization and application in clinic.

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Human lymphocyte function-associated antigen 3 (hLFA3) has been identified as an important T cell accessory molecule. Rhesus monkeys (Macaca mulatta) have been widely used as animal models for human immune disorders. Due to the species-specificity of immune system, it is necessary to study M. mulatta LFA3 (mmLFA3). In this study, the gene encoding mmLFA3 CD2-binding domain (mmLFA3Sh) was amplified by polymerase chain reaction (PCR) and genetically fused to human IgG1 Fc fragment in pPIC9K to construct the expression plasmid pPIC9K-mmLFA3Sh-Ig. Approximately 3-4 mg mmLFA3Sh-Ig protein was recovered from 1 L of inductive media, and mmLFA3Sh-Ig produced by the P. pastoris can bind to the CD2 positive cells, and suppress the monkey and human lymphocytes proliferation induced by Con A and alloantigen in a dose-dependent manner. These results suggested that mmLFA3Sh-Ig might be used as a novel tool for pathogenesis and experimental immunotherapy of Rhesus monkey immune disorders.

Objective To investigate the effects of methylprednisolone(MP) on the expression of matrix metalloproteinase(MMP)-9 and airway inflammation in murine models of asthma. Methods Thirty female BALB/c mice were randomly divided into asthma group,MP group and control group(n=10).Murine models of acute asthma were established by ovalbumin(OVA) via peritoneal injection and intranasal instillation.The pathological changes of lung tissues were observed with HE staining,and cell quantitation was conducted in bronchalveolar lavage fluid(BALF).The expression of MMP-9 protein was determined by immunohistochemistry and gelatin zymogram,and the expression of MMP-9 mRNA was detected by RT-PCR. Results Compared with control group,there were more significant airway spasm and more infiltration of inflammatory cells in histologic examination,and there was higher eosinophil cell quantitation in BALF in asthma group(P
