Objective To explore the application effect of Sandwich teaching method in clinical teaching in the department of neurosurgery.Methods Totally 144 clinical medicine students were divided into 2 groups:Sandwich teaching group (n=72) and traditional teaching group (n=72).The analysis of test and the questionnaire of the students were conducted after the course.Comparison between the two groups was made using independent sample t test and measurement data were expressed as as ± s.P＜0.05 signifies statistically significant differences.Rank sum test was used to compare the distribution of the test scores.Results The test score was statistically higher in Sandwich teaching group than control group [(76.38 ± 10.84) vs.(69.67 ± 10.50)].And the main distribution of the test scores was 70～90 in Sandwich teaching group while 60～80 in control group.Questionnaire showed that the scores of Sandwich teaching group were statistically higher than those ofthe control group in five aspects such as enhancing self-learning ability,improving the ability to analyze and solve problems,and so on.Conclusions Sandwich teaching method achieves good teaching effect and it is worth recommending in clinical teachifig.

Objective:To study the effects of glutamine on the rehabilitation and the immune function in patients with acute stroke. Methods: The study included 57 patients with cerebral ischemia and 29 patients with brain hemorrhage.Nutritional and immune function parameters were evaluated at admission and after 2 weeks following stroke respectively.Neurological deficit was also evaluated by the Chinese Stroke Scale at admission and after 28 days following stroke.The infective complications were investigated. Results:At the same duration after acute stroke,the extent of neurological deficit recovery was significantly lower in the control group than the glutamine group.The rate of the infective complications was significantly higher and it's duration was significantly longer in the control group than the glutamine group.The degree of nutriture and immune function deteriorating was significantly severer in the control group than the glutamine peptide group. Conclusion:Parenteral glutamine supplements is helpful for the rehabilitation and in preventing deterioration of nutrition status and immune function following acute stroke.

Objective To investigate the hemostasis effect of alginate dressing for puncture point bleeding after peripherally inserted central catheter (PICC) by ultrasound-guided modified Seldinger technique (MST).Methods Between November 2013 and May 2016, 538 cases of cancer in our department underwent PICC, including 270 cases from November 2013 to February 2015 selected as control group (after PICC was successfully placed, sterile gauze and 3M transparent film were used to fix the puncture point) and 268 cases from March 2015 to May 2016 selected as observation group (after PICC was successfully placed, alginate dressing, sterile gauze and 3M transparent film were used to fix the puncture point).The patients in both groups were given 20 minutes of pressure for puncture point and elastic bandage compression fixation for 24 h.The degree of puncture point bleeding and times of dressing change in 24 h and 24-72 h between the two groups were compared.Results In the observation group, mild, moderate, and severe bleeding was seen in 232 cases, 34 cases, and 2 cases within 24 h, and in 242 cases, 25 cases, and 1 case between 24-72 h, respectively.In the control group, mild, moderate, and severe bleeding was seen in 12 cases, 196 cases, and 62 cases within 24 h, and in 21 cases, 212 cases, and 37 cases between 24-72 h, respectively, with significant differences (Z=-18.647, P=0.000;Z=-18.768, P=0.000).In the observation group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 232 cases, 33 cases, 3 cases, and 0 case within 24 h and in 242 cases, 25 cases, 1 case, and 0 case between 24-72 h, respectively.In the control group, there were zero, once, twice, and ≥3 times of puncture point dressing change in 12 cases, 196 cases, 51 cases, and 11 cases within 24 h and in 21 cases, 209 cases, 37 cases, and 3 cases between 24-72 h, respectively, with significant differences (Z=-18.560, P=0.000;Z=-18.755, P=0.000).Conclusion The hemostasis effect of alginate dressing for puncture point bleeding after ultrasound-guided PICC by MST is satisfactory.

Objective To investigate the changes and its clinical significance of serum brain-derived neurotrophic factor (BDNF) level and plasma tissue plasminogen activator( t-PA ) level in patients with amnestic mild cognitive impairment (aMCI). Methods 99 aMCI patients (aMCI group) and 99 matched normal controls (NC group) were recruited for the present study. Multi-dimension neuropsychologic tests were used to extensively assess cognitive function of subjects. An enzyme-linked immunosorbent assay was applied to measure serum BDNF level and plasma t-PA level. The correlation analysis between serum BDNF level and plasma t-PA level tested by ELISA and cognitive function were also made. Results (1) The results neuropsychologic tests in aMCI guoup were significantly lower than those in NC group (all P

Objective : To realize unifying gas source adapter's standards for different ventilators while the one be connected to different terminal units of central gas source.The ventilators can be used at every clinical department of hospital normally.Methods: A conversion adapter for terminal units of ventilators and central gas source was designed and developed.After experiments on airtightness,the conversion adapter was used and connected into different terminal units for unified format and universality.Results: The conversion adapter for ventilator's gas source was universally adapted to ventilators in all hospital's clinical departments.

An overall improvement of teaching quality is the core task of the reform and the development of higher education. Based on the analysis of the main factors of affecting the teaching quality in universities and combined with the implementation of “views on improving the overall qual-ity of higher education”by the Education Ministry, countermeasures for improving the teaching quality of undergraduates have been proposed such as increasing higher education funds investment to im-prove the condition of running a school, paying attention to the construction of teaching management staff to improve the level of teaching management, establishing Teacher Development Research Center to consolidate the fundamental position of undergraduate teaching , utilizing the high-quality social resources to implement the collaborative education innovation, and improving the personnel training system to strengthen the teaching quality standard .

To explore the clinical value of the color Doppler flow imaging (CDFI))in diagnosis of vascular disease in the lower extremities of patients with type 2 diabetic mellitus(2DM), 102 patients with 2DM and 20 normal controls were included in this study. The values of vessel intimal-media thickness(IMT), the size of plaque, vessel diameter, percentage of diameter stenosis, percentage of the peak systolic velocity acceleration at stenosis orifice, and velocity wave pattern were obtained with CDFI. The study indicated that the incidence of vasculer disease in the lower extremities as shown by CDFI was higher than that as assessed by clinical manifestations only. By CDFI,the severity of the stenosis or the obstructive lesions of blood wessels in lower extremities was better evaluated,moreover quantitative indexes for clinical diagnosis were provided.

Objective To investigate the relationship between sICAM-1 and colorectal carcinoma metastasis. Methods ELISA was used to detect sICAM-1 level in specimens from 50 cases colorectal cancer patients' serum and 30 cases controls. Results Serum sICAM-1 level in colorectal cancer was significantly higher than that in controls (P 0.05), that in patients with metastasis was significantly higher than that in control(P

The epidermal growth factor receptor (EGFR) is overexpressed in many epithelial cancers,and is commonly caused by EGFR gene amplification and gene mutations. The most frequently occurring variant,the type III mutation (EGFRvIII) ,is characterized by an inframe deletion of exons 2-7 of the coding sequence. It is expressed only in tumors and not found in normal tissues, and therefore represents an attractive therapeutic target. The tumor therapy methods targeted for EGFRvIII include immu-notherapy, ribozyme, RNA interference, etc.
