Now medical undergraduates are faced with a series of problems in the clinical practice.Instructors should work well on students' education work to improve the effect and quality of clinical practice.

According to the training of all levels and all kinds of personnel during our hospital's digital construction and implementation process,this article discussed the training char-acteristic of computer skill and the teaching principle for doctors and nurses

Objective To realize the isolation of multidrug-resistant organisms (MDROs)from ward environment, and provide evidence for clinical prevention and control of MDRO transmission.Methods Patients with MDRO in-fection in a stomatology hospital from September 2012 to July 2014 were as trial group,12 randomly selected pa-tients without MDRO infection were as control group,environmental object surface in patients’ward were taken specimens and performed culture,isolated organisms were identified and performed antimicrobial susceptibility tes-ting.Results Of 44 patients with MDRO infection,13 patients’surrounding environment were detected MDROs,the total detection rate was 29.55%(13/44).The detection rate of methicillin-resistant Staphylococcus aureus (MRSA),multidrug-resistant Acinetobacter baumannii (MDRAB),and methicillin-resistant Staphylococcus epidermidis (MRSE)were 45.45%(5/11),66.67% (2/3)and 66.67%(6/9)respectively.Detection rates of MRSA from nasal cavity and hands of MRSA-infected patients were 72.73% and 54.54% respectively,from nasal cavity and hands of patients’caregivers were 36.36%and 18.18% respectively.The difference in bacterial count between trial group and control group was not significantly dif-ferent (all P >0.05).Conclusion Isolation rate of MDROs from ward environment of MDRO-infected patients is higher than that of non-MDRO-infected patients,monitoring,cleaning and disinfection for MDRO-infected patients’surrounding environment should be strengthened,so as to prevent the spread of MDROs in hospital.

Objective To discuss the feasibility and superiority of EST combined with LC in treating cholecystolithiasiswith common bile duct stones.Methods Patients underwent LC(laparoscopic cholecystectomy) preceded by EST(endoscopic sphincterotomy) and removal of common bile duct stones.ENBD(Endoscopic nasal biliary drainage tube)was placed if EST failure and then the patient underwent LC+laparoscopic biliary duct exploration(LCBDE),or open operative bile duct exploration.Results In 91 of the 99 cases,LC preceded by EST and stone removal was successful,while EST following LC was successful in 3 cases,and stone removal by EST was unsuccessful in 3 cases.Two cases less than 15 years of age underwentLC+LCBDE through the cystic duct and did not undergo EST.Three cases,who had EST failure,underwent LC+LCBDE with primary suture of the common bile duct or LCBDE with T-tube drainage of commonbile duct,or open bile duct exploration with primary suture of the common bile duct(ENBD was in place).All patients were discharged from hospital without serious complications.Conclusions EST combinedwith LC in treating cholecystolithiasis with common bile duct stones is a safe and effective method.Combination of endoscopic and laparoscopic procedures fully reflects the advantage of minimally invasive therapy.

Objective To observe the clinical efficacy and safety of Azithromycin Sequential Therapy in the treatment of mycoplasma pneumonia for children.Methods 112 children with mycoplasma pneumonia were randomly divided into observation group and control group,each 56 cases.The observation group was treated with Azithromycin Sequential Therapy in the treatment,while the control group was treated with erythromycin lactobionate anti infection treatment.The clinical efficacy was compared between two groups after treatment,the clinical symptoms disappeared time and drug adverse reaction occurred the situation.Results The total effective rate of the observation group was 96.43%,which was significantly higher than 80.36% of the control group,the difference was statistically significant (χ2 =7.04,P <0.05).The fever,cough,pulmonary rales disappearance time of the observation group were (3.74 ± 1.58)d,(3.24 ±0.47)d,(5.58 ±2.23)d,which were significantly shorter than (4.68 ±1.71 )d,(4.64 ± 0.97)d,(7.82 ±2.70)d of the control group(t =4.27,4.68,4.59,all P <0.05).The gastrointestinal reactions, local pain,rash,the elevation of ALT of the observation group were significantly lower than the control group,the difference was statistically significant (χ2 =4.26,7.04,7.03,5.23,all P <0.05 ).Conclusion Azithromycin Sequential Therapy for the treatment of mycoplasma pneumonia in children has the advantages of good clinical effica-cy,fast effect,high safety.

Faced with the development of medical computer information and lacking of medical students’ information education, integrated education of medical computer information capacity is explored and implemented. Medical students’ entire cognition on computer information is improved, their working and learning ability and efficiency are improved obviously by education, and thus medical students’ comprehensive ability is enhanced effectively.

Objective To investigate the refraction change and nursing character in myopic amblyopia during the perceptual learning treatment. Methods Refraction of 54 children (98 eyes) with myopic amblyopes were selected,which were selected from the amblyopia clinic between 2007 and 2009, the spherical diopter, astigmatism and spherical equivalent were collected before and after perceptual learning,the refractive dynamic was compared according to the degree of amblyopia. Results The spherical average annual growth of myopic amblyopia during treatment was 0.52D, the growth of astigmatism was 0.03D;the spherical equivalent average annual growth was less than 0.50D accounted for 57.14%. The dynamic changes of spherical or SE of mild, moderate and severe amblyopia had significant difference, but the cylinder had not significant difference in change. Conclusions The treatment of perceptual learning in patients has little effect on the growth of refraction in myopic amblyopia, however, it is still necessary to pay close attention to refraction changes of in myopic amblyopia in the course of treatment.

A Ni-based rare-earth perovskite LaNiTiO3 nanoparticles was synthesized and its catalytic activity was investigated. Based on this, a simple and quick nonenzyme electrochemical sensor was fabricated with stable and reliable performances for the determination of hydrogen peroxide (H2 O2 ). The techniques of X-ray diffraction, FT-IR spectra, transmission electron microscopy, X-ray fluorescene spectroscopy and scan electronmicroscope were used to characterize the composition, structure and morphology of as-synthesized sample. The sensor based on this nanomaterial was investigated and optimized by cyclic voltammetry and current-time techniques. The results showed the working electrode modified with LaNiTiO3 (0. 5 g / L, 8. 0μL) in 0. 1 mol/ L NaOH exhibited good catalytic properties for H2 O2 . Under the optimum conditions, the sensor performed excellent properties, such as quick response time ( about 2 s ), a wide linearity (0. 2 μmol/ L -8. 0 mmol/ L), a low detection limit of 0. 05 μmol/ L ( S / N = 3 ), a high sensitivity of 957 μA (mmol/ L) -1 cm-2 , good reproducibility and anti-interference ability, which was better than those of some other biosensors reported recently. So, it may be used for the analysis and detection of H2 O2 in practical samples such as biomedicine.

ObjectiveTo summarize the experience of nursing patients with heat illness combined with respiratory failure. Method The nursing records of 13 patients with heat illness combined with respiratory failure were reviewed for summarizing the nursing measures.Result After treatment and nursing care,12 of them were discharged and 1 died from multiple organ dysfunction. Conclusions Rapid cooling is key to the success of rescue.The nursing measures include keeping respiratory tracts unobstructed and preventing complications from artificial airway and mild hypothermia therapy.
