Objective To investigate the health care workers'(HCWs) knowledge and attitude towards perioperative warming as well as patients' warming status, provide reference for warming in perioperative period and reduce surgical site infection(SSI).Methods Convenience sampling was used to select 198 HCWs in surgical department and operating room as well as 160 patients undergoing operation.HCWs were investigated by referring foreign literatures and designing questionnaires, on-site observation method was used to collect information about warming measures implemented for surgical patients.Results The median (quartile range) of scores of HCWs' knowledge and attitude towards patients' perioperative warming were 9 (2.25) and 25 (1.25) respectively.There was no statistical significance in scores of knowledge and attitude among HCWs with different age, education degree and occupation(all P>0.05).The awareness rates of hypothermia, active warming, and passive warming modes were 21.21%, 43.94%, and 30.81% respectively.80.30%, 89.90%, and 86.36% of HCWs thought that it was essential to keep warming before, during and after surgery.68.13% of surgical patients were warmed by covering cotton quilt and shoulder pad during operation.Conclusion HCWs hold positive attitude towards perioperative warming, but they lack sufficient knowledge about perioperative warming, it is necessary to improve facilities of perioperative warming.

Objective To investigate the relationship of radiation dose with the volume and late toxicity of the sternocleidomastoid muscle ( SM) in patients with nasopharyngeal carcinoma. Methods SM was divided into upper part and lower part based on the lower edge of cricoid cartilage. Patients were divided into three groups according to the prescribed dose for clinical target volume at the lower neck ( CTV2 ) ( 0, 54,60 Gy) . The dosimetric parameters included Dmean , V66 , and V60 for the upper, lower, and whole SM. SM was delineated and the volume was calculated on computed tomography images in the treatment planning system before and at 6, 12, and 18 months after treatment. The anteroposterior and transversal diameters of SM at C3?C4 , C4?C5 , C5?C6 , and C6?C7 levels were measured and recorded. Late toxicity of neck skin and SM was evaluated according to the Common Terminology Criteria for Adverse Events V4 .0 criteria. Between?group comparison was made by t?test or Kruskal?Wallis non?parametric test. Between?group comparison of the sample rate was made by one?way analysis of variance. The correlation analysis was made by Spearman correlation. Results There were significant difference in SM volume between the three time points after treatment ( P=0. 000) . At 12 or 18 months after treatment, the volume of SM wasignificantly reduced ( P=0. 000,0. 000);the reduction in SM volume was significantly correlated with V66 of the SM and the upper SM ( P=0. 015,0. 020) . At 18 months after treatment, SM fibrosis was significantly correlated with V60 of the upper SM ( P=0. 030);the fibrosis of neck skin was significantly correlated with the Dmean and V60 of the upper SM ( P=0. 029,0. 005) . Conclusions In order to prevent the incidence of the fibrosis of neck skin and SM, the dose homogeneity should be as high as possible, while the number of hot spots should be as small as possible.

Objective To study transaction log and apply its analysis to hospital information security to prevent data loss and treat abnormal data.Methods The application of transaction log was described in log backup and database recovery,and the optration of log analysis was explored in HIS.Sqlplus and Ftp tools in Oracle were used to analyze the transaction log.Results The tracking and analysis of the log files contributed to making clear the incident,finding program bug,getting back lost data.Conclusion Log backup,database recovery and log analysis were of great importance for hospital information security,and log analysis has to be emphasized on in the future.

Objective To investigate the pattern of antihypertensive medication prescribing in outpatients from the Second Hospital of Tianjin Medical University, and analyze the shortcoming and deficiency compared with 2010 Chinese guidelines for the management of hypertension. Methods A total of 154 262 electronic prescribing for outpatients with hy-pertension, from January-December 2012 in a Grade 3A hospital in Tianjin, were enrolled in this retrospective survey. Data of commonly used antihypertensive medication and combination therapy in patients were analyzed. The patient data collected were divided into different groups according to age, gender, high blood pressure level and the onset of the season. Results (1)The list of the drugs commonly used for treating hypertension in outpatients were calcium antagonist (52.3%), angiotensin receptor blockers (34.0%),βblockers (25.9%), angiotensin-converting enzyme inhibitors (12.1%), fixed-dose combination (11.0%) and diuretics (1.4%).(2)The fewer combination therapy was found in outpatients than that of monotherapy (43.9%vs 56.1%). Some prescriptions were not routinely recommended by the Guideline (4.6%).(3)The combination therapy used in patients with stage 3 hypertension was higher than that of patients with stage 1or stage 2 hypertension (44.5%vs 37.7%vs 37.7%, P<0.01). The rate of combination therapy was significantly higher in cardiology department than that of other clini-cal departments (P<0.01). The combination therapy tended to be used in the elderly patients than that of non-elderly pa-tients (P<0.01). The number of prescriptions was lower in summer than that of other seasons,but the rate of combination therapy was higher in summer than that of spring, autumn and winter (P<0.01). Conclusion The prescriptions of combina-tion therapy and diuretic were inadequate in outpatients with hypertension. These findings indicate the difference between clinical prescription and the guideline for the management of hypertension.

Objective To study the effects of wet paking the ligustrazine phosphate to cure the effusion when using chemotherapy medicine. Methods Divided 120 patients into 2 groups randomly. In the experimental group, ligustrazine phosphate was used to cure the effusion, while in the control group, the traditional method was used. Compared the effects of differences between the two groups. Results The effects about curing the effusion in the experimental group was significant better than those of in the control group. Conclusion It is an effective method about wet packing the ligustrazine phosphate to cure the effusion when using chemotherapy medicine.

Objective To analyze the prognostic factors in patients with initially diagnosed bone-only metastatic nasopharyngeal carcinoma (NPC). Methods We collected the data of 68 patients with initially diagnosed bone-only metastatic NPC admitted to The Affiliated Tumor Hospital of Shantou University Medical College from 1997 to 2015. Forty-nine patients received chemoradiotherapy. The Kaplan-Meier method was used to calculate the overall survival rate;the log-rank test was used for univariate prognostic analysis;the Cox model was used for multivariate prognostic analysis. Results The median follow-up was 953 months. The 1-, 2-, 3-, and 5-year overall survival ( OS) rates were 53%, 38%, 21%, and 15%, respectively. The median OS time was 134 months. The univariate prognostic analysis showed that spinal metastases, the number of bone metastases, lactic dehydrogenase level before treatment, the radiotherapy technology and dose for primary tumor, and the short-term outcome of primary tumor were associated with OS ( P=002, 001, 000, 002, 002, 001 ) . The multivariate prognostic analysis showed that ≤3 bone metastases, dose to primary tumor>65 Gy, and intensity-modulated radiotherapy ( IMRT) were favorable prognostic factors for OS ( P=003,002,004) . Conclusions For patients with initially diagnosed bone-only metastatic NPC, active treatment ( IMRT, dose to primary tumor>65 Gy) should be considered for those with ≤3 bone metastases to achieve a complete response of primary tumor.
