This article summarizes 32 cases of the SCI patients suffered from bladder stones.Respects relating to causes,characteristic,diagnosis,treatment and prevention of bladder stones after SCI are discussed in the article.In order to decrease or avoid complication of indwelling urethral catheter,the patients with neuropathic bladder dysfunction are treated by intermittent catheterization.If it is necessary for SCI patients to indwell urethral catheter,we must strengthen management of the catheter and renew a catheter in time(once a week).

Objective To investigate the relationship between interpersonal acceptance and loneliness of college students.Methods 510 college students were administered by interpersonal acceptance scale(IASCS)and UCLA loneliness scale.Results (1)As a whole,there exists great capable difference of interpersonal acceptance according their genders,grades(t=5.37,P＜0.01,t=12.56,P＜0.01).(2)Significant negative correlation exist great capable difference about the scores of loneliness between the higher and lower acceptance of college students(P＜0.01).(4)Analysis of regression indicates that interpersonal acceptance has significant predictable effects on loneliness.Conclusion Interpersonal acceptance is the important factor influencing loneliness in college students.

Objective To evaluate the effects of etomidate preconditioning on etomidate-induced toxicity to rat adrenal cortical cells in vitro.Methods After being primarily cultured for 7-9 days,the rat adrenal cortical cells at the exponential growth phase were seeded into 96-well culture plates (1 × 106 cells/ml) and cultured for 24 h.The cells were then randomly divided into 3 groups with 6 wells in each group:control group (group C),etomidate group (group E),and etomidate preconditioning group (group EP).In group E,the cells were incubated with 700 μmol/L etomidate for 24 h.In group EP,the cells were incubated with 1.25 μmol/L etomidate for 1 h,then washed out and incubated with 700 μmol/L eomidate for 24 h.The cell viability was determined by CCK-8 assay and the concentration of cortisol was determined by ELISA.Results Compared with group C,the cell viability and cortisol concentration were significantly decreased in E and EP groups.Compared with group E,the cell viability and cortisol concentration were significantly increased in group EP.Conclusion Etomidate preconditioning can reduce etomidate-induced toxicity to rat adrenal cortical cells in vitro.

Objective To improve the biocompatibility of the metallic stent used for interventional treatment. Methods Inner coatings, outer coatings and micro-porous coatings were made using the solution-injection method, and salt crystallite with demanded size was added in order to develop micro-porous coatings. Results The optical concentrations of polyurethane solution and of salt crystallite (for micro-porous coatings) were obtained, and the corresponding processes were developed. Conclusion The poly-coated stent retains its elasticity, and it become very convenient to develop stents carrying drugs. Its effects on animals ard under test.

Objective To compare the application effect of the Sandwich teaching method and case teaching method in undergraduate nursing students in clinical nursing teaching.Methods 114 undergraduate nursing students were divided into observation group and control group by random number table,and each group had 57 students.The control group used case teaching method,which the teacher used case to teach,while the observation group used the Sandwich method,including teacher guides,group discussions,cross discussion,group report,teacher's comments,case analysis,etc.Results The score of theory test in observation group was 86.14±7.24,which was significantly higher than 77.46±6.97 of the control group (t=6.515,P ＜ 0.01);Students of observation group thinking yes in the nine survey items was 85.96％ to 100.00％.Conclusions The effect of Sandwich teaching method is better than case teaching method,and has high satisfaction of nursing students.

Objective To study the effect of amelogenin (AML)on the migration,adhesion and proliferation of periodontal ligament stem cells (PDLSCs).Methods STRO-1 +PDLSCs were selected by Flow cytometer.The transwell system was used to detect the effect of AML on migration of PDLSCs.Cells attachment assay was used to detect the effect of AML on adhesion of PDLSCs.MTT was used to detect the effect of AML on the proliferation of PDLSCs.Results The results of transwell showed that AML could induce the migration of PDLSCs with positive correlation.Cells attachment assay showed that the adhesion of PDLSCs was effected by AML as well,and the effect was in-creased with the extension of incubation time.Results of MTT showed that AML could promote the proliferation of PDLSCs in a dose depend-ent manner.Conclusion AML could increase the proliferation,adhesion and migration potential of PDLSCs.

Objective To investigate the effectiveness of training at morning shift meeting in improving healthcare-associated infection(HAI) prevention and control among health care workers(HCWs) in newly established hospital departments.Methods On July 11-22, 2016, HAI management full-time personnel performed training for HCWs about HAI prevention and control at morning shift meeting of 8 newly established clinical departments and 1 laboratory, the questionnaire survey was conducted before, immediately after, and 3 months after training, training effectiveness was evaluated.Results A total of 239 HCWs were required to receive training, including 85 doctors (35.6％), 150 nurses (62.8％), and 4 technicians (1.7％).The knowledge of HAI prevention and control that most HCWs wanted to know was occupational exposure and occupational precaution(85.6％);most HCWs wanted to obtain knowledge of HAI through training in their respective department by HAI management full-time personnel(87.1％).Total awareness rates of HAI knowledge before, immediately after, and 3 months after training were 45.1％, 96.7％, and 83.9％ respectively, difference was significant(P<0.001);comparison among groups showed that HCWs'' awareness in influencing factors of HAI, hand hygiene opportunity, isolation measures, and medical waste classification 3 months after training was significantly lower than immediately after training(all P<0.001);the average scores of HAI prevention and control knowledge among HCWs immediately after and 3 months after training were both higher than before training(P<0.001);average score of HAI prevention and control knowledge among HCWs 3 months after training was lower than that of immediately after training(P<0.001).Conclusion The training at morning shift meeting of clinical departments can improve the awareness of HAI prevention and control knowledge among HCWs.

Objective To establish a new RP-HPLC method for simultaneous determination of chlorogenic acid,forsythin, and baicalin in shuanghuanglian powder for injection after ultrasonic atomization. Methods Hypersil ODS2 C18(250 mmí4. 6 mm,5 μm) was used as the chromatographic column. The mobile phase was methanol-0. 2% phosphate acid solution (4060). Flow rate was 1. 0 mL·min-1 . Sample volume was 5μL. Column temperature was 30℃. Detection wavelength was 324 nm at 0-10 min and 277 nm at 10-25 min. Results Contents of chlorogenic acid,forsythin, and baicalin had good linear relationship with the respective peak area (r≥0. 999 7) within the scope of the sample volume. The RSD was <2% for precision, reproducibility, and stability. Recovery rate was 98. 50%-101. 12% (n=6). Conclusion The method is rapid, accurate and reproducible, with high resolution. It can determine the content of three kinds of components at the same time. The three components in shuanghuanglian powder for injection did not change significantly before and after ultrasonic atomization.

Objective:To study dynamic changes of fragile histidine triad(FHIT) gene expression in ionizing radiation injury and radiation carcinogenesis. Methods: BEAS-2B cells were divided into 0.5,1,2,4,8,16 Gy irradiation groups and control group. In 24 h, 72 h and 10 d after irradiation, the expression of FHIT gene was studied with single-cell RT-PCR and DNA sequencing separately. Results: Different types of FHIT gene mutations occured in different phases after irradiation with different doses (All mutations were exon deletion mutations by DNA sequencing), while abnormal FHIT gene was not detected in control group. The percentage of mutation in 0.5,1,2,4,8,16 Gy dose groups was 52.6%,66.7%,57.9%,76.5%,64.7% and 81.3% respectively 24 h after irradiation;17.6%,22.2%,50.0%,47.4%,47.1% and 68.4% respectively 72 h after irradiation;and 21.1%,25.0%,60.0%,57.9%,61.1% and 68.4% respectively 10 d after irradiation. Conclusion: These results suggest that ionizing radiation can cause deletion of FHIT gene.
