Objective To investigate the effect of head extension angle to glottis exposure by using three-dimensional CT reconstruction sagittal plane images of upper airway.Methods There were 80 patients,aged 7-78 years old,who had been scanned by helical CT in the head and neck.Reconstructed images were obtained by AW4.4 workstation and the following parameter was measured:angle α(A0 group),the angle created by the upper central incisor and root of epiglottis(angular vertex) and midpoint of glottis.Reconstructed images were printed according to the actual size of human body in a ratio of 1∶ 1,then the images were cut off from the upper central incisor to root of epiglottis by a section of arcs.Increasing the degree of angle α by clockwise to hypothetically increase the angle of head extension.The glottis was exposed by using a paper-made laryngoscope(Macintosh) model,and the success rate of glottis exposure was recorded when the degree of angle α was respectively increased 10°(A10 group),20°(A20 group),and 30°(A30 group).Results Compared with A0 group,the success rate of glottis exposure increased significantly in A10 group,A20 group and A30 group.The success rate of glottis exposure in A20 group and A30 group was significantly higher than A10 group.Compared with A20 group,the success rate of glottis exposure obviously increased in A30 group.Conclusion Based on CT reconstruction images of upper airway,we can analog study the effect of head extension angle to glottis exposure.

Objective To evaluate the impact of warmed and humidified CO2 on the gynecological laparoscopic operation. Methods We searched keywords related to gynecological laparoscopic and CO2 pneumoperitoneum temperature and humidity on Pubmed and Wanfang database, then analyze the postoperative pain, analgesic consumption, core temperature, operation time, length of hospital stay. Results 17 publications included into the meta analysis after screening. Compared with the standard laparoscopy, warmed and humidified CO2 can reduce postoperative pain and prevent intraoperative hypothermia. No significant difference in postoperative analgesic consumption, postoperative core temperature, duration of recovery and hospital stay, endoscope lens fog and operation time. Conclusions Only few beneficial effects on postoperative pain and core temperature have been identified in this meta-analysis, though more studies are probably needed to study the real impact of warmed and humidified CO2 for laparoscopic procedures.

The matrix metalloproteinases(MMP) are important enzymes that regulate developmental processes,maintain normal physiology in adulthood and have reparative roles in specific stages after an insult to the nervous system.Conversely,the concordant presence and significant up-regulation of several MMP members in virtually all neurological conditions result in pathological lesions.Thus,the MMPs have double functions,capable of mediating repair and recovery on the one hand and being involved in producing injury on the other.This article highlights the beneficial roles of MMP-2 and MMP-9 in normal and reparative processes within the nervous system and discusses the detriments of both encountered in spinal cord injury and central nervous system cancers,and we also review the availability of MMP inhibitors for clinical use.

Objective:The aim of this study was to examine whether PSA levels were affected by BMI and the influence of BMI on the clinical application of PSA.Methods:A total of 856 males who had routine health checkups between January 2006 and July 2007 in our hospital were recruited for this study.Those with a documented history of prostate carcinoma were excluded.Height,weight, and total PSA were measured.The BMl was calculated from measured height and weight [BMl=weight(kg)/height(m)2].Results:The serum PSA(ng/mL)levels were 2.97±0.15 in the normal weight group,2.53±0.12 in the overweight group,and 2.01±0.16 in the obese group(P＜0.05).A negative correlation was found between PSA and BMI(r=-0.130,P＜0.05)and weight(r=-0.142.P＜0.05).A positive correlation was found between PSA and age(r=0.306,P＜0.05).Con-clusion:BMl is associated with PSA.As BMI increases, serum PSA decreases.The current data suggest that such an influence should be considered in the clinical application of PSA.

In an uncertain and dynamic environment,medical research institutions must often balance between the usual medical research and emergent medical research.We interpreted this as a balance between exploitation-oriented innovation and exploration-oriented innovation.We pointed out that a flexible organization can coordinate the competition of scientific research resources between the two kinds of innovation; then we built an organizational flexibility model based on resource flexibility and coordination flexibility,and extended the model to medical research institution.And finally,we discussed the strategies for increasing organizational flexibility.

Objective To analyze the curative effect of posterior internal fixation and fusion on patients with spinal fractures, and to provide the basis for clinical application. Methods A total of one hundred and eighty?eight patients with orthopedic incision treated in the First Affiliated Hospital of Xinxiang Medical University from March 2013 to December 2016 were divided into the observation group ( 98 cases with posterior internal fixation fusion ) and the control group ( 90 cases with anterior internal fixation fusion ) . The clinical curative effects of the patients ( including Cobb angle,spinal nerve function,complications and the success rate of surgery ) , postoperative visual analogue score ( VAS ) , hospitalization time, operation time were compared. Results In the observation group,the VAS score before operation was (6. 89±6. 89) points and reduced to (2. 70±1. 33) points after operation,the pain decreased significantly after treatment (t=26. 099,P<0. 001). The VAS score of the control group lowered from (6. 85±6. 85) points to (5. 05±1. 35) points,and the pain decreased significantly after treatment ( t=10. 704, P<0. 001 ) , and the postoperative pain in the observation group was significantly reduced than that in the control group ( t=12. 016,P<0. 001) . There were significant differences between the observation group and the control group in operation time,intraoperative blood loss,incision length and hospitalization time ( ( 141. 91 ± 35. 42 ) min vs. ( 198. 82 ± 38. 61 ) min, ( 509. 72 ±113. 65) ml vs. (823. 40±108. 54) ml,(10. 25 ± 0. 84) cm vs. (18. 83±1. 58) cm,(10. 59±12) d vs. (15. 37±1. 52) d,t=10. 541,19. 315,47. 015,24. 681,P<0. 001) . The total effective rate of the observation group was 86 cases ( 97. 96%) , and ineffective rate of the observation group was 2 cases ( 2. 04%) . In the control group, the effective and ineffective rates were 75 cases ( 83. 33%) and 15 cases ( 16. 67%) , the difference in effective rate between the two groups was statistically significant (χ2 = 12. 202, P<0. 001 ) . Conclusion Posterior internal fixation fusion is effective in the treatment of spinal fracture,which can reduce the postoperative pain,shorten the hospitalization time,less complication and high success rate. It is suitable for clinical promotion.
