Objective To understand the development status of healthcare-associated infection (HAI)management organizations in Xinjiang region,and effectively improve the management level of HAI in Xinjiang.Methods 101 secondary and above medical institutions in Xinjiang were selected by cluster random sampling method,a retrospec-tive survey was conducted from February 15 to March 31,2016.Development of HAI management organizations in each hospital in 1995,2000,2005,2010,and 2015 were surveyed,statistical analysis of the surveyed results were conducted.Results Of 101 hospitals,22 were tertiary hospitals,79 were secondary hospitals.In 2005 and before, more than 70% of hospitals with >300 beds and 20% of hospitals with< 100 beds carried out HAI management, about 50% of hospitals with >300 beds and less than 5% of hospitals with< 100 beds set up HAI management committees.In 2015,all hospitals carried out HAI management and set up HAI management committees as well as HAI management departments.In 2005 and before,the main HAI management professionals were nursing staff, accounting for about 80%;in 2000 and before,> 50% of full-time professionals received secondary vocational school and below education,in 2005 and after,about 80% of full-time professionals received at least college and above education;in 2000 and before,> 70% of full-time professionals didn’t receive training.In 2015,the percentage of nursing staff engaged in HAI management dropped to 65.90%,and doctors and other professionals both accounted for 17.05%,40.09% of HAI management professionals received university education,92.08% par-ticipated in autonomous region level and above training,1.98% didn’t receive training.Conclusion HAI infection management organizations in Xinjiang region in the past 20 years have developed,the allocation of professionals and professional quality can not meet the needs of HAI infection management in this region.

Objective To evaluate the test-retest reliability and validity of the 3-dimensional Digital Goniometer for Cervical (3DDGC) in measurement of cervical range of motion. Methods 39 healthy participants were measured of cervical range of motion 2 times in 1 hour with 3DDGC by one observer, and with cervical range of motion (CROM) device once. The intraclass correlation coefficient (ICC) of test-retest and the Pearson correlation coefficient between devices were caculated. The measurement errors were evaluated with standard er-ror of mean (SEM). Results The ICC was 0.89 of 3DDGC as the cervical rotation to the left, and it was 0.90-0.98 of the other directions, with the SEM of 2.07-3.85° . The Pearson correlation coefficient was 0.73-0.92, with the SEM of 1.66-3.17° . Conclusion 3DDGC is valid and reliable in test-retest in measuring cervical range of motion, which need more research clinically.

The process of exercise regulating bone metabolism is complicated, which involves a number of signaling pathways. A large number of studies in vitro have indicated that mechanical stress regulates bone metabolism by Wnt, bone morphogenetic protein (BMP), and osteoprotegerin (OPG)/receptor activator of NF-κB ligand (RANKL)/receptor activator of NF-κB (RANK) signaling pathways. Both the in-tensity and frequency of mechanical stress have varing impact on bone tissue and cells. Plenty of studies in vivo also have shown that exer-cise regulates bone metabolism by key factors in bone metabolism signaling pathways. This paper reviewed the effects of exercise on bone metabolism pathways and their mechanisms.

Objective To investigate the situation of the activities of daily living(ADL)for elderly people in Changsha,and analyze the influencing factors. Methods Questionnaire survey on ADL was held in 2239 elderly people(ranging from 60 to 91 years old),and the influencing factors including age,sex,family structure,marital status,education level,occupation,common chronic diseases and medical care consciousness were analyzed. Results Going to the toilet irregularly hadthe highest injury rate in physical self-maintenance viability(18.2%).But in instrumental ADL,the highest injury rate occurred while shopping(26.3%).Advanced age,living alone,losing spouse,sickness and the lack of medical care awareness were the major factors that influenced the ADL of the elderly people. Conclusions The ADL is an important indicator which reflects the health condition of elderly people.Advanced age,living alone,losing spouse,having many chronic diseases and lacking in medical care awareness are risk factors.

Objective To investigate the effects of informed consent on emotion and immunologic function in patients with laryngopharynx cancer.Methods Sixty patients with laryngopharynx cancer were divided into group A and group B by random digits table with 30 cases each group.In group A patients were informed consent,and in group B family were informed consent.The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores,as well as cellular immunity function were measured before informed consent and 2 weeks after surgery.Results The SAS,SDS scores and levels of cellular immunity function between two groups,differences was no statistically significant (P ＞ 0.05).The SAS,SDS scores 2 weeks after surgery in group A were significantly less than those in group B [(43.17 ± 7.63) scores vs.(47.84 ± 8.46) scores,(37.43 ± 8.69) scores vs.(42.67 ± 9.82) scores,P ＜ 0.05].The CD3,CD4,NK cells 2 weeks after surgery in group A were significantly higher than those in group B (0.5762 ±0.0941 vs.0.5160 ± 0.0821,0.3832 ± 0.0751 vs.0.3140 ± 0.0561,0.1521 ± 0.0491 vs.0.1163 ± 0.0422,P ＜ 0.05),CD8 and CD4/CD8 between two groups differences was no statistically significant (P ＞ 0.05).Conclusion The informed consent for patients with laryngopharynx cancer may relieve emotional disorders and avoid immunologic function decreasing.

Objective To summarize the characteristics of nosocomial infections in the patients treated in intensive care unit (ICU).Methods The incidence of nosocomial infections was monitored in ICU from March 2012 to August 2012.The incidence rate of infection was adjusted with Average Severity of Illness Score (ASIS)score and analyzed in relation to three invasive pro-cedures.Pathogen distribution of nosocomial infections in ICU was also analyzed.Results Nosocomial infection was identified in 357 of the 3 700 ICU patients (9.65%).The overall daily infection rate was 30.34‰,specifically,49.10‰ for ventilator asso-ciated pneumonia (VAP),13.86‰ for catheter-related bloodstream infections (CRBSI),and 1.09‰ for catheter-associated urinary tract infections (CAUTI).Of the 688 bacterial isolates,gram negative bacteria accounted for 82.70%.The top three bacterial species were Acinetobacter baumanii ,Pseudomonas aeruginosa ,and Klebsiella pneumoniae .Conclusions ICU is the focus for surveillance of nosocomial infections.Objective investigation is critical for nosocomial infection surveillance.

Objective To explore the occurrence of surgical site infection(SSI)in patients in different levels of hospitals.Methods SSI among patients in 47 hospitals at 0:00-24:00 of May 16,2012 were investigated by medi-cal record reviewing,doctor inquiry,and bed-side visiting.Results A total of 5 977 surgical patients were investiga-ted,SSI prevalence rate was 1 .76%.SSI prevalence rate in secondary hospitals was higher than tertiary hospitals (χ2 =9.337,P =0.002);SSI prevalence rates in clean-contaminated and contaminated incision in secondary hospi-tals were both higher than tertiary hospitals (χ2 =4.315,8.129,both P <0.05);departments with high SSI preva-lence rates were general surgery,orthopedic,and neurosurgery;the major isolated pathogens were Escherichia coli , Staphylococcus aureus ,and coagulase negative Staphylococcus .Conclusion SSI rates of different types of incision and different departments are varied,corresponding prevention and control measures should be taken.

Synchronous bilateral primary breast cancer refers to the simultaneous occurrence of primary cancers in both breasts. The overall morbidity is low. However, with the detection of occult breast cancer increasing recently, it shows an upward trend. The pathogenesis is not yet clear, old age, family history of primary breast cancer, sclerosing adenopathy of precancerous lesions and pathological characteristics of first cancer are currently recognized risk factors. Compared with unilateral breast cancer, prognosis for synchronous bilateral primary breast cancer is poor. Raise the risk awareness of high-risk women, check regularly to find non-palpable lesions as soon as possible. By taking various preventive treatments for patients with high-risk unilateral breast cancer, the incidence of breast cancer can be effectively reduced and the prognosis of patients can be improved. By reviewing the literature at home and abroad, it systematically expounds the risk factors, histopathological features, prognosis and preventive treatment of synchronous bilateral breast cancer.
