Objective: To explore the clinical value of real-time ultrasound-guided closed reduction of nasal bone fracture. Methods: Sixty patients with clinically confirmed nasal bone fractures were randomly divided into experimental group and control group (each n=30). Both groups were treated with closed reduction of nasal bone fracture under general anesthesia. Patients in experimental group were treated with real-time ultrasound-guided closed reduction, while those in control group were treated with closed reduction of nasal bone fracture under traditional visual and palpation. After reduction, effect of reduction was evaluated with three-point method based on nasal CT scan. The second reduction rates, hospitalization time and post-operative CT scores were compared between the two groups. Results: The second reduction rate of fracture was 0 in the experimental group, whereas 13.33% (4/30) in control group (χ2=4.286, P=0.038).The hospitalization time of experimental group was 4 days, of control group was 5 days (Z=-5.024, P<0.001). The scoring of experimental group were 3 points and 2 points respectively in 19 cases and 11 cases, while of control group were 3 points in 11 cases, 2 points in 16 cases and 1 point in 3 cases. The reduction effect of experimental group was better than that of control group (χ2=6.059, P=0.048). Conclusion: Real-time ultrasound-guided closed reduction of nasal bone fracture is accurate and reliable, which can reduce the risk of second reduction of fracture and avoid X-ray radiation, also effectively shorten the hospitalization time of patients and improve the satisfaction of both doctors and patients.

The treatment of limb fractures with closed reduction and minimally invasive fixation with C-arm or conventional X-ray guidance has been widely accepted and gradually developed due to less trauma and rapid healing.However,the radiation damage of X-ray can not be ignored.With the continuous progresses of ultrasound technology,the application of ultrasound in clinic is involved not only in the diagnosis of fractures,but also in the closed reduction and fixation of fractures.The research progresses of ultrasound-guided closed reduction and minimally invasive fixation of limb fractures were reviewed in this article.

Objective To explore value of high-frequency ultrasound-guided minimally invasive fixation treatment for metacarpus and phalange fractures.Methods Totally 26 patients of acute metacarpus and phalange fractures were selected and randomly divided into experimental group and control group (each n =13).The patients in experimental group underwent ultrasound-guided closed reduction,while in control group underwent C-arm X-ray fluoroscopy-guided reduction.Then the patients in two groups were followed up,and the curative effect of both methods were observed.Results The successful rate of closed reduction was 76.92％ (10/13) in experimental group,while was 84.62％ (11/13) in control group (x2=0,P=1.00).C-arm fluoroscopy was performed (0.62±1.19) times in experimental group,and (3.46±0.78) times in control group (t=-7.21,P＜0.01).The average healing time of fracture was (5.45±0.64) weeks in experimental group and (5.71±0.78) weeks in control group.The excellent and good rate of total active motion (TAM) was 84.62％ (11/13) in experimental group and 92.31％ (12/13) in control group,respectively.The average grip strength was (32.22±2.44) kg in experimental group,and (34.11±2.74) kg in control group (all P＞0.05).Conclusion High frequency ultrasound-guided minimally invasive fixation is reliable in treatment of metacarpal and phalangeal fractures,which can significantly reduce X-ray radiation.

Objective To explore the effect of health education combine with nursing intervention on improving the awareness of patients′ tuberculosis ( TB) knowledge effectiveness. Methods A total of 1 186 cases of TB from June 2012 to June 2014 in our hospital were selected. According to accepted care measures, patients were divided into two groups, 593 cases received health education combined with nursing intervention were as the observation group, while another 593 cases received conventional care were as the control group. The questionnaires about TB knowledge, vital signs and prognosis of patient satisfaction outcomes were analyzed. Results Before accepting health education, the difference of knowledge of TB between the two groups was not statistically significant (P>0. 05). After the health education combined with nursing intervention, 540 (91. 1%) patients in the observation group got a score of TB knowledge over 60, which was significantly higher than 402 patients (67. 8%) in the control group (P<0. 05). 402 (67. 8%) patients in the observation group got a score of TB knowledge over 80, which was significantly higher than 207 patients (34. 9%) in the control group (P<0. 05). The total score of quality of life in the observation group were (603. 6 ± 127. 4), which was significantly higher than (512. 9 ± 114. 9) in the control group (t =2. 59,P<0. 05). The rate of satisfaction in observation group was significantly higher than that in the control group (Z=91. 3,P<0. 05). Conclusions Health education combined with nursing intervention can effectively improve the knowledge and awareness of TB patients. The psychological status and quality of life had significantly enhanced, thus it is worthy of further promotion in clinical practice.

Objective To investigate the effect of Hospital-Community-Family integrated management in the rehabilitation of patients with chronic gastric ulcer. Methods From June 2012 to June 2014, a total of 250 patients with chronic gastric ulcer were divided into the observation group ( n=125 ) and the control group (n=125) according to the random number table.

Objective To investigate the antimicrobial susceptibility of spectinomycin?minocycline?azithromycin and sparfloxacin to mycoplasma(Uu and Mh)and therapeutic effect of spectinomycin to my-coplasma infection in genitourinary tract.Methods①The susceptibility test:each of the4drugs was divided into two concentrations.One was at1?g/mL(sensitive concentration)and the other was at4?g/mL(resistant concentration).If mycoplasma does not grow in both concentrations,it means the drug tested is sensitive.If it grows in both concentrations,the drug tested is resistant.If mycoplasma grows in lower concentration and does not in higher concentration,it means moderate sensitive.②Treatment regimen:Spectinomycin was injected,2g/d IM,for7-10days as a course of treatmeant.Patients were followed-up7days later and2~4weeks after treatment.Results①Among1658specimens,519were found Uu positive,and61Mh positive.The resis-tance rates of Uu to4different drugs were:7.7%for minocycline,21.4%for sparfloxacin,13.9%for azithromycin and7.3%for spectinomycin.Whereas,those of Mh were:18.0%,45.9%,54.1%,and29.5%re-spectively.②The clinical effect of spectinomycin was:out of43treated patients,37(86.0%)cured,4(9.3%)markedly improved,2(4.7%)failed.Total effective rate was95.3%and so was the elimination rate of my-coplasma.Conclusion The resistant rate of mycoplasma to spectinomycin is lower than that to minocycline?azithromycin and sparfloxacin,and the former is widely used in the treatment of mycoplasma(especially Uu)infection,with a satisfactory clinical effect.

Background The health and safety climate of workplace has an important impact on the physical and mental health of workers. There is no available scale for the evaluation of workplace health and safety climate in China at present. Objective This study aims to sinicize and evaluate the reliability and validity of the Health and Safety Climate Survey. Methods The English version of Health and Safety Climate Survey was translated to Chinese and back-translated to English, and followed by expert evaluation to develop a Chinese version. Quota sampling method was used to select 2600 employees from 16 enterprises and public institutions in Pudong New Area of Shanghai and to evaluate the reliability and validity of the Chinese version of the scale. Structural validity, convergent validity, and discriminant validity were included in validity evaluation. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to test structural validity. In EFA, an acceptable factor loading of items on their respective dimensions was > 0.60. In CFA, an acceptable root mean square error of approximation (RMSEA), a standard absolute fitness index, was < 0.05. Comparative fit index (CFI) and parsimony-adjusted non-normed fit index (PNFI), measures of incremental improvement and fit, > 0.90 indicated a good fit. Convergent validity was evaluated by average variance extracted (AVE), and an AVE > 0.50 indicated good convergent validity. Discriminant validity was determined as good by the square root of AVE greater than the correlation coefficient between latent variables. Cronbach’s α coefficient was used to evaluate the internal consistency of the scale; the internal consistency considered was very good with an α > 0.90. Cronbach’s α coefficient may cause underestimation of reliability in the case of error correlation. Therefore, composite reliability (CR) calculated based on structural equation model >0.70 indicated that the CR was good. Results The response rate was 95.69%. The Chinese version of Health and Safety Climate Survey included 22 items belonging to six dimensions which was extracted by the EFA, and the cumulative variance contribution rate was 74.79%. The corrected RMSEA was 0.045, the PNFI was 0.970, and the CFI was 0.975 in the CFA, indicating good fit. The dimensional AVE values were all greater than 0.50, indicating good CV. The square root of AVE was greater than the correlation coefficient between latent variables, indicating good DV. The Cronbach’s α was 0.90 for the total scale and were above 0.70 for all dimensions. The CR was 0.93 for the total scale and were above 0.70 for all dimensions, indicating that the overall reliability of the scale was good. Conclusion The Chinese version of Health and Safety Climate Survey has good reliability and validity, and can be further improved in field application.
