The phenomenon of insufficient learning motivation is universal among college students,yet especially significant among those scientific students in medical colleges.Based on the investigation of learning motivation among students in science and engineering in medical colleges,this paper analyzes the causes of their insufficient learning motivation and comes up with certain countermeasures.

Objective To explore the ideal postoperative nursing methods of repair the lacerateon of lacrimal canaliculus. Methods Using pigtail probe to repair the lacerateon of lacrimal canaliculus in 49 patients, observed the postoperative nursing points in different clinical phases. Results There were 2 patients had the anstomotic stoma split, 1 patient had the canaliculitis. There were 46 patients had successful extubation. Conclusion The Worst lacrimal probe is an satisfactory and reliable method to repair the lacerateon of lacrimal canaliculus. The detailed interpretation and the skillful nursing care are the guarantee for successful operation.

Objective To examine the bacteriostasis of baicalin against Escherichiacoli strain carrying NDM-1 gene.Methods Minimal inhibitory concentration(MIC)and minimal bactericidal concentration(MBC)were determined by broth dilution method.Synergy function was designed withcheckerboard method.Anti-infection effect in vivo of baicalin was observed in mice with bacteremia.Results In vitro antibacterial tests showed that the MIC and MBC baicalin were 8 mg/ml.Synergistic inhibitory effect was observed between baicalin and imipenem (FIC=0.125).In vivo inhibition experiments showed that ba-icalin had decreased the mortality of 25% of Escherichiacoli Strain carrying NDM-1 gene infection in mice.Conclusion Ba-icalin has antibacterial effect on NDM-1 E.coli.

Objective: To analyze the expression of mecp2 gene at mRNA and protein;Cerebral cortex level in the cerebral cortex of the normal Wistar rat throughout development. Methods: We chose the 15th day (E15), 17th day (E17), 19th day (E19) of embryo period, the day of birth (P0), the 7th day (P7), the 14th day (P14), the 28th day (P28) of postnatal period, and adulthood as analyzing time points. The expression of mecp2 gene at mRNA level was analyzed by real time PCR and Northern blot. The expression of MeCP2 protein was analyzed by Western blot. Results: There was one type of mecp2 mRNA transcript (approximately 10 kb) expressed in the cerebral cortex of the normal Wistar rat. The expression level of mecp2 mRNA varied subtly during the development. There was one type of MeCP2 protein (75 000) expressed in the cerebral cortex of the normal Wistar rat. The expression level of MeCP2 protein remained the lowest on E15, from E19 to adulthood the expression levels of MeCP2 protein increased dramatically compared with that on E15. From P7 to adulthood, the differences of expression between two time points were subtle. Conclusion: The expression level of MeCP2 protein increases as the neurons in the cerebral cortex of normal Wistar rat grow mature. This indicates that MeCP2 protein is very important to neuron's maturation, and probably has relationship with maintaining maturation state of neurons.

Objective To investigate the phenotype and genotype in a carbapenem resistant L.adecarboxylata strain.Methods Microbial identification and drug susceptibility test was done with VITEK II Compact.Carbapenemases genes were detec-ted by PCR methods.Results The strain of carbapenem resistant L.adecarboxylata produced IMP-1 carbapenemase.Con-clusion L.adecarboxylata was found only rarely in the clinical isolates.This was the first Isolate of L.adecarboxylata pro-ducing IMP-1 metallo-beta-lactamase.

Objective: To investigate the effect of motivational interviewing on functional exercise in postoperative breast cancer patients. Methods: A total of 128 postoperative breast cancer patients admitted to our hospital from March 2016 to October 2017 were selected and divided into control group and observation group before and after motivational interviewing. The control group was given routine functional exercises guidance, while the observation group was given motivational interviewing on the basis of the control group. The self-efficacy and functional exercise compliance of the two groups were evaluated before intervention, on the day of discharge, and 3 months after discharge. The shoulder joint mobility of the two groups was evaluated 3 months after discharge. Results: Repeated measures analysis of variance showed that there were statistically significant difference between the control group and the observation group in C-SUPPH (F_intervention=5.608, P=0.020) and Postoperative Functional Exercise Compliance Scale for Breast Cancer(F_intervention=6.776, P=0.010); The shoulder joint mobility of the observation group was superior to the control group at 3 months after discharge (U=2.128, P=0.033). Conclusion Motivational interviewing can improve self-efficacy and functional exercise compliance of postoperative breast cancer patients, and promote the recovery of shoulder joint activity function.

Purpose: This study aimed to describe the clinical response to five-step systematic therapy (FSST) in the management of plugged ducts and mastitis. FSST was a comprehensive milk stasis dredging treatment, which contained five steps to make the milk out of the plugged duct. Methods: This retrospective study included 922 breastfeeding women, 714 with plugged ducts, and 208 with mastitis who received FSST from June to September 2017. The breast pain score, swelling degree, and range of breast induration were recorded pre-FSST and post-FSST. Results: After a single FSST, pain score and swelling degree were significantly improved (both p < .001) in all cases. After FSST, the mean breast pain relief score was 1.69 ± 0.70, whereas the mean swelling fade away degree was 1.61 ± 0.62. In the subgroup analysis, pain score and swelling degree were significantly improved (both p < .001) in the plugged ducts group and the mastitis group. The score of pain relief in the plugged ducts group was less than that in the mastitis group (1.63 ± 0.68 vs. 1.91 ± 0.70, t = 5.30; p < .001), whereas improvement of swelling fade away was greater in the plugged ducts group than the mastitis group (1.65 ± 0.64 vs. 1.48 ± 0.56, t = 3.49; p = .001). The composition ratio of changes in induration range between the two groups was statistically different (Pearson χ2 = 137.87, p < .001), of which more obvious improvement in the plugged ducts group than the mastitis group (χ2 = 25.65, p < .001). Conclusion FSST can relieve pain, reduce breast swelling and range of induration, and for plugged ducts or mastitis varied degree differently.
