Objective To observe the matching between the straight short femoral cephalomedullary nail (PFNA-Ⅱ) and the femoral anterior bow in Chinese patients with intertrochanteric fracture. Methods A retrospective study was performed to analyze the postoperative lateral X-rays of 158 patients with intertrochanteric fracture who had been treated by PFNA- Ⅱ between August 2009 and December 2010.They were 35 men and 123 women,with a mean age of 77.2 years.The relationships between the distal tip of the medullary nail and the anterior cortex of the femur were observed according to a self-designed 6-grade scale (grade 0:central location of the nail tip in the medullary canal; grade 1:deviated location without contact with the cortex; grade 2:contact＜ 1/3 cortex thickness; grade 3:contact ＞ 1/3, ＜ 2/3 cortex thickness; grade 4:contact ＞ 2/3 cortex thickness; grade 5:perforation; posterior deviations in grades 1 to 5 presented as minus).The theoretical distance was measured as if the anterior protrusive nail tip had been placed back to the central axis.The degree of the curvature and its corresponding radius were calculated by the geometric method. Results Of the 158 patients,the distal tip of PFNA- Ⅱ was located centrally along the axis of femur canal in 30 cases(19.0％ ),posteriorly to the central axis in 10 cases(6.3％ ),and anteriorly to the central axis in 118 cases (grades 1 to 3; 74.7％ ),of which 55 cases experienced irritation caused by the contact between the distal tip and the anterior cortex (grades 2 to 3％ ).The mean theoretical distance needed to put back the nail tip to the canal central axis was 1.42 ± 0.18 mm in the 17 cm nails,1.77 ± 0.39 mm in the 20 cm nails,and 2.46 ±0.20 mm in the 24 cm nails.Their corresponding curvature arcs were 2.51° ±2.40°,2.13° ± 1.65° and 2.09° ± 0.98°,and their curvature radii were 1483 ± 818 mm,2329 ± 1293 mm,and3710 ± 1957 mm,respectively. Conclusions There is a significant mismatch between the current short straight celphalomedullary nail (PFNA- Ⅱ) and the femoral anterior how in Chinese population.A curvature design is needed for the short cephaiomedullary nails to match the femoral anterior how of Chinese population.

BACKGROUND: The incidence rate of spondylolysis of lumbar vertebral arch in recruits is higher during the training, and it affects the normal training. OBJECTIVE: To analyze the correlation of the incidence rate of spondy lolysis of lumbar vertebral arch with training and the original lesions at waist in recruits. DESIGN: A randomized sampling survey. SETTING: Department of Orthopaedics, the 97 Hospital of Chinese PLA. PARTICIPANTS: Totally 100 male recruits aged 18.7 years averagely en rolled in 2003 were involved in the survey. METHODS: The 100 recruits were followed up for the whole course, the X-ray examination at lumbar vertebrae of right, lateral and two-slope positions were observed before training and after 100-day reinforced training. MAIN OUTCOME MEASURES: The incidence rates of spondylolysis of vertebral arch, and whether there was slippage and other aggravations in those with spondylolysis before were mainly observed. RESULTS: All the 100 recruits entered the analysis of results. ① The in cidence rate of spondylolysis of vertebral arch before and after training: Be fore training, 5 cases had spondylolysis of L5 vertebral arch, and the incidence rate was 5%. At the end of the 100-day training, 8 cases had spondylolysis of lumbar vertebral arch, and the incidence rate increased to 8%. ② The results of X-ray examination before and after training: The Xray examination showed that isthmus narrowing of left and L5 vertebral arch occurred in 2 cases and 1 case respect ively, and spondylolysis of bilateral L5 vertebral arches occurred in 5 cases, including 1 case of degree I slip page before training. At the end of the 100-day training, the degree I slip page and below occurred in 3 of the 5 cases with spondylolysis of bilateral L5 vertebral arches before, another 3 cases with original narrowing of lumbar vertebral arch all had breakage. CONCLUSION: The incidence rate of spondylolysis of vertebral arch is associated with the training intensity. It suggestes that the examination of spinal cord should be reinforced in enrolled recruits, and the items of Xray examination at lumbar vertebrae of right, lateral and two-slope positions should be added.

Breast cancer is caused by somatic mutation. As such, somatic mutation in breast cancer should be described to eluci-date the underlying mechanism. Next-generation sequencing has provided new insights into the genomics of breast cancer. New genes were identified and exhibited a relationship with breast cancer. Although these genes mutated at a low frequency, such genes in different cases could be categorized into specific pathways. Mutational signatures could be found in some cases, but such signatures were gener-ally not related to environmental exposure. Studies on intra-tumoral heterogeneity have revealed the ubiquitous presence of sub-clones in breast cancer;however, a major clone is also observed, accounting for>50%of tumor cells. Current advancements show that breast cancer genomics has been integrated into personalized medicine. Furthermore, a genome-informed and personalized molecular sub-typ-ing and treatment of breast cancer can be developed in the future.

BACKGROUND:In the condition of exercise physiology, adenosine triphosphate-sensitive potassium (KATP) channel plays an important role in many aspects, such as regulation of coronary artery tension, exercise-induced myocardial protection effect and delay of skeletal muscle fatigue. OBJECTIVE:To review and investigate the role of KATP in exercise in order to provide theoretical reference for understanding mechanism underlying exercise regulation of body’s metabolism. METHODS: A computer-based online search of PubMed and VIP databases was performed for articles related to molecular structure, biological function and regulatory role of KATP as wel as correlation of KATP with coronary artery, myocardium, skeletal muscle fatigue and exercise ability published from January 1991 to June 2014. The keywords were “KATP channels; adenosine triphosphate; sports; myocardium; ion channels” in English and Chinese, respectively. Finaly, 42 relevant articles were included in result analysis. RESULTS AND CONCLUSION: Coupling with celular energy metabolism and cel membrane excitability, KATP channel is one of the effectors for myocardial protection in response to various physiological and pathological stresses. Prolonged endurance training can increase the expression of skeletal muscle and myocardial KATP, which may be an adaptive performance of the myocardium and skeletal muscle in response to exercise stress. KATP may participate in regulation of coronary blood flow. Myocardial KATP plays an important protective role for aleviating myocardial ischemia-reperfusion injury induced by exercise. When skeletal muscle fatigue occurs, the activation of KATP is helpful to prevent muscle fiber damage and cel death due to excessive consumption of ATP, in favor for the fast recovery from fatigue. The relation between KATP and exercise ability stil needs further research.
