Background: This study aimed to evaluate the effects of standard rescue procedure (SRP) in improving severe trauma treatments in China. Methods: This study was conducted in 12 hospitals located in geographically and industrially different cities in China. A standard procedure on severe trauma rescue was established as a general rule for staff training and patient treatment. A regional network (system) efficiently integrating prehospital rescue, emergency room treatments, and hospital specialist treatments was built under the rule for information sharing and improving severe trauma treatments. Treatment outcomes were compared between before and 1 year after the implementation of the SRP. Results: The outcomes of a total of 74,615 and 12,051 trauma cases were collected from 12 hospitals before and after the implementation of the SRP. Implementation of the SRP led to efficient cooperation and information sharing of different treatment services. The emergency response time, prehospital transit time, emergency rescue time, consultation call time, and mortality rate of patients were 24.24 ± 4.32 min, 45.69 ± 3.89 min, 6.38 ± 1.05 min, 17.53 ± 0.72 min, and 33.82% ± 3.87% (n = 441), respectively, before the implementation of the standardization and significantly reduced to 10.11 ± 3.21 min, 22.39 ± 4.32 min, 3.26 ± 0.89 min, 3.45 ± 0.45 min, and 20.49% ± 3.11%, separately (n = 495, P < 0.05) after that. Conclusions: Staff training and SRP can significantly improve the efficiency of severe trauma treatments in China.

Objective To evaluate the clinical effectiveness of growth hormone (GH) for hip fractures. Design Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Library (2011, 3 issue), PubMed (1966 to October 2011), EMBASE (1974 to October 2011), OVID database (1963 to October 2011), Chinese Bio-medicine database (1978 to October 2011), China Journal Full-text Database (1979 to October 2011), and VIP database (1989 to October 2011). Randomized controlled trials (RCTs) of GH treatment for hip fractures were included. We assessed the quality of included trials according to the Cochrane Handbook for Systematic Reviews of Interventions Version. The Cochrane Collaboration's software RevMan 5.0 was used for meta-analysis. Results 3 RCTs with a total of 162 hip fractures patients were included. Results of GH compared to placebo treatment showed that IGF-I levels significantly increased in the short term, but no significant differences in the long term. Additionally, there was no statistical difference in adverse events. Only one trial reported the measurement of bone mineral content (BMC), which showed that GH group was unchanged while the placebo group lost BMC at both 4 weeks and 8 weeks. Only one study measuring BMC showed no significant differences in the change of the MBI scores between GH group and placebo group; however, the changes from baseline in the hGH group were less than that in the placebo group among the older than 75 years group. Owing to the difference of measurement indexes in those studies, we could not perform a meta-analysis. Conclusions With the low quality of current evidence, GH may be effective in hip fractures. More carefully designed, double-blinded and placebo-controlled randomized trials with large numbers of participants about GH in the treatment of hip fractures are required.

Speech quality of patients with oral or oropharyngeal carcinoma was assessed by perceptual and acoustic-phonetic analyses. Speech recordings of running speech of patients before and 6 and 12 months after treatment for oral or oropharyngeal cancer and of 18 control speakers were evaluated regarding intelligibility, nasality and articulation, which revealed deteriorated speech in 20% of the patients before treatment, and in 75% 6-12 months after treatment. Acoustic analyses comprised formant, duration, perturbation and noise measures of the vowels /i/, /a/, and /u/ and were performed on the speech samples 6 months after treatment and the controls. Patients appeared to have a smaller vowel space compared to controls, which was clearly related to speech intelligibility. Furthermore, voice perturbation appeared to be higher in patients. Although oropharyngeal treatment does not effect the function of the larynx itself, the acoustic coupling between source and filter may effect the smoothness of the voicing characteristics. The presented speech analyses may serve as part of an outcome measurement protocol for assessing efficacy of speech rehabilitation.
