Objective To explore the relationship between metabolic syndrome(MS) and cerebral stroke type,complication and prognosis.Methods Clinical data of 568 cerebral stroke patients with MS(MS group) and 209 cerebral stroke patients without MS(no-MS group) were compared and analyzed.Results In MS group,the incidence of cerebral infarction was significantly higher(93.0%) than that in the no-MS group(85.2%)(P

Objective: To explore the function of network information in the medical research teaching. Methods: To analyze the function of network information in the medical research, combined with the current actual medical research teaching, to understand correctly the related problems, and find the corresponding appropriate solutions. Results: In medical research teaching, the students should be led to use correctly the network tool for keeping track the research forefront, solving scientific problems, broadening the research mindset; avoiding addiction, split personality and internet plagiarism. Conclusion:In the medical research teaching, the students should be guided to use the network tools correctly, which maximize its effect.

In the treatment of human epidermal growth factor receptor 2 (Her-2) overexpressing breast cancer,some patients have drug resistance to trastuzumab.Potential mechanisms of resistance to trastuzumab include impaired access of trastuzumab to Her-2 ; alternative signaling from insulin-like growth factor-1 receptor (IGF-1R),hepatocyte growth factor receptor (HGFR) and so on; aberrant downstream signaling caused by loss of phosphatase and tensin homologs deleted from chromosome 10 (PTEN);phosphatidylinositol 3-kinase catalytic alpha polypeptide gene (PIK3CA) mutation; over-expression of heat shock protein 90 (HSP90) and CD44. Additionally,potential strategies for overcoming resistance to trastuzumab include using new targeted medicines,such as pertuzumab,lapatinib and trastuzumab-DM1.

Objective To investigate the application value of tuberculosis infection of T cells spot test in the diagnosis for pulmonary tuberculosis in elderly patients with chronic obstructive pulmonary disease(COPD).Methods According to test different ways,64 elderly COPD patients with pulmonary tuberculosis were divided into the two groups.The control group(n =32)was checked by tuberculosis antibody test,and the study group(n =32)received T cells infected with tuberculosis spot test.The two sets of results were observed and compared.Results The study group by T cell spot test TB infection,29 cases were detected positive(90.63%),3 cases of negative(9.37%);tuberculosis antibody detection by the control group,23 cases were detected positive(71.88%),9 negative patients (28.12%).Compared the two groups,the study group had higher positive rate(χ2 =3.954 7,P <0.05),and nega-tive rate was lower(χ2 =3.914 7,P <0.05).Conclusion Tuberculosis infection T cell spot test in the diagnosis of pulmonary tuberculosis in patients with COPD in the elderly has greater value,more accurate diagnosis,reliability and worthy of promotion.

Airway obstruction in children is a rare,in recent years,with the development of CT technology and the development of fiber bronchoscopy,the number of cases of children with tracheal stenosis has increased year by year,but difficult clinical problem,with no clear agreement on optimal therapeutic approach.Stenting of the airway has been used successfully in adults,and is an attractive alternative in children.Fundamental differences of pediatric compared to adult use include the benign nature of most stenoses,the narrow and soft airways of children,the required long-term tolerance and adaptation to growth.So it is controversial in the indications.

BACKGROUND:Bionic structure is one of the most important goals of scaffold design in tissue engineering. However, the majority of the bionic scaffolds do not have the capacity of sustained release of growth factors.
OBJECTIVE:To fabricate a novel biomimetic nanofibrous heparin/gelatin scaffold and investigate the characterization of the scaffolds including the microstructure, the mechanical strength andin vitro recombinant human bone morphogenetic protein-2 (rhBMP-2) release.
METHODS:Heparin-conjugated gelatin was prepared by chemical crosslinking and mixed with gelatin at different ratios. Nanofibrous composite scaffolds with different ratios of heparin-conjugated gelatin (0, 20% and 40%) were fabricated by using a thermaly induced phase separation combined with particle leaching technique. The amount of conjugated heparin in the scaffolds, scaffold microstructures and mechanical strength were detected and observed. The release kinetics of rhBMP-2 from the scaffolds with different concentrations of heparin conjugated gelatin was detected using ELISA method.
RESULTS AND CONCLUSION:The composite scaffolds possessed abundant porosities, good mechanical properties, and biomimetic nano-structures. The macroporous size was 250-420 μm. When the ratio of heparin-conjugated gelatin was 0, 20% and 40%, the content of heparin in the scaffolds was 0, (12.82±2.49) and (25.08±3.69) mg/g, respectively, with significant differences; the elastic modulus of the composite scaffolds was (299±38), (286±40) and (236±33) kPa, respectively, with insignificant differences (P > 0.05). With the increase in the content of heparin-conjugated gelatin, the rhBMP-2 adsorption capacity of the nanofibrous heparin/gelatin scaffold is improved, thereby significantly reducing the burst release of rhBMP-2 and prolonging the releasing time.

Objective To investigate and analyze the residents′knowledge and satisfaction on basic public health services in five districts of Gansu ,to judge the implementation effect of the current policy ,in order to provide the suggestion to improve the effect of the implementation of the policy of basic public health services .Methods Based on typical sampling method ,1 688 rural and urban residents had been investigated coming from five counties in Gansu by using questionnaires to survey .Results The de‐gree of residents′knowledge about the policy was low (57 .23% );the residents could know about the policy through a variety of ways ,and mainly for medical staff to promote by approaching their homes ;91 .94% of surveyed residents thought that policy service was more convenient when they were accepting ;90 .99% of surveyed residents thought that they satisfied with the service attitude of staff ;82 .35% of surveyed residents believed that the policy service effects was obvious ;90 .11% of surveyed residents overall satisfied with the service of policy .The above results were different in proportion in various counties(P<0 .05) .Conclusion The degree of residents′knowledge and satisfaction on basic public health services in five districts of Gansu still needs to be improved .
