Objective To observe the effect of fluid resuscitation on hemodynamies and oxygen in severe trauma patients. Methods Parameters of hemodynamic and oxygen metabolism in different fluid volume resuscita-tion in 24 severe trauma patients who were injured on abdominal were measured. Results By fluid resuscitation, as the systolic blood pressure was raised from 80～90 mm Hg(1 mm Hg=0.133 kPa) to 100～120 mm Hg,cardiac in-dex rose from (2.0±0.5 ) L/(min·m2) to (3.2±0.6) L/(min·m2) (P<0.05), systemic vascular resistance index rose from (1857.6±750.2) dyn·s/(cm5·m2) to (3741.5±862.1) dyn·s,/(cm5·m2) significantly (P<0.05). Meanwhile, oxygen delivery index rose from (301.1±74.1) ml/(min·m2) to (554.1±80.0) mL/(min·m2) (P<0.05), and oxygen consumption index also rose (99.7±51.4) mL/( min·m2) to (147.2± 60.1) mL/(min·m2) remarkably (P<0.05), the rate of oxygen expenditure decreased from (33.1±9.1) % to (26.6±8.0) % significantly (P<0.05). Conclusion Large volume resuscitation maybe benefit to the improve-ment of hemodynamics and oxygen metabolism in the emergency resuscitation.

Thirty - six cases were treated with Fufang Xiebai (FX) capsule and compared with control group. There was significant difference (P

Objective To investigate the status of clinical using of blood products in Shanghai area,clinicians' understanding on transfusion knowledge and consciousness of prevention of transfusion risk.Methods Two hundreds of clinicians who were randomly selected from level two and above hospitals of Shanghai were inquired by questionnaire.Data including understanding of transfusion techniques,prevention of transfusion risk,application of blood components and grasp of new techniques were collected and analyzed.Results Among all interviewed clinicians,those who realized the importance of transfusion on clinical work,who understood the basic contents of clinical guideline for transfusion issued by Ministry of Health People's Republic of China,and who had the basic knowledge of blood component products and transfusion applications account for 62%,60% and 81% respectively.But only 28% clinicians knew all the side effects,27.3% learned the new techniques of transfusion,including leukocyte reduced,virus elimination,clinical application of irradiation.This investigation also showed 97% clinicians would like to accept training of transfusion,68% thought they need more relevant information about prevention of transfusion risk.Conclusions Clinicians in Shanghai area had the basic knowledge of clinical guideline for transfusion,but some knowledge of transfusion were insufficient including blood components and their applications,side effects and new techniques of transfusion.Clinicians in Shanghai had active response for being trained on knowledge of transfusion.

Mild cognitive impairment caused by craniocerebral trauma is the key points and difficulties in judicial authentication. This article has comparative analysis of each mode of event-related potential (classical Oddball, Eriksen flanker task and so on), which can provide a more objective method for such craniocerebral trauma cases in clinical forensic judicial authentication.

Objective To develop a portable ventilation device to cool and dehumidify for the astronauts who work or move dressed in spacesuit in the atmospheric environment on the ground.Methods Based on the requirement which the astronauts need when they are dressed in spacesuit on the ground,the overall design project has been brought forward,which expounds the design scheme of DC brushless centrifugal fan,power supply,regulation of blowing rate,intelligent monitor on system parameters,organic light-emitting diode(OLED)display,device configuration,software,and so on.Results The portable device for spacesuit ventilation and heat-regulation,which has been developed,can work stably and safely.It has convenient operation mode and practical human-machine interface.Meanwhile,the device has compact configuration.It is light and portable.Conclusion The portable device for spacesuit ventilation and heat-regulation carry out the portable ventilation and heat-regulation for the astronauts of China dressed in spacesuit dress for the first time.It also fulfils the spacesuit dryness after use and usual maintenance.

Aim To investigate the effect of irbesartan and spironolactone on expressions of connective tissue growth factor(CTGF),P-p38MAPK proteins during vascular remodeling in renovascular hypertensive rats(RHR).Methods Renovascular hypertension was induced by two kidney one clip(2K1C)operation.8 weeks later,RHRs were given irbesartan or(and)spironolactone for 8 weeks.After 8 weekstreatment,the morphometric measurements were performed in the mesenteric arterioles.Concertration of carboxyterminal propeptide of typeⅠprocollagen(PⅠCP)and N-terminal propeptide of type Ⅲ procollagen(PⅢNP)in blood serum was measured by enzyme linked immunosorbent assay method,and the media collagen area was assessed by collagne-specific Picro-sirius red staining with computerized video processing.Expressions of collagen type I,CTGF,P-p38MAPK proteins were detected using immunohistochemistry respectively.Results The arterial systolic pressure was attenuated significantly after the treatment of irbesartan,and this effect could not be enhanced by spironolactone.The media thickness over lumen ratio,media cross-sectional area over luminal area ratio of mesenteric arterioles,concertration of PⅠCP and PⅢNP,media collagen area,and expression of collagen typeⅠwere significantly increased in RHRs but ameliorated by irbesartan and spironolactone.Meanwhile,the expressions of CTGF,P-p38MAPK proteins were up-regulated in RHRs but blunted significantly after the treatment of irbesartan and spironolactone.The combined treatment had the synergic effects.Conclusions There is a synergistic effect of attenuating extracellular matrix(ECM)producing and amelioration of vascular remodeling(VR)by combined use of irbesartan and spironolactone.It maybe related to the expressions of CTGF and P-p38MAPK proteins down regulated by these two drugs.

Objective To establish an accurate method for determining the content of three components in Fufang Buwu Syrup. Methods TLC scanner was selected to detect three components with silica gel G thin layer plate. The sample was separated by using cyclohexane-ethyl acetate-methylenechloride-formic acid (3∶1∶1∶0.2),λS=300 nm. Results The linearity between peak area and ferulic acid was achieved in the range of 0.36-0.84μg, psoralen was achieved in the range of 0.12-0.28 μg, emodin was achieved in the range of 0.01-0.05 μg. The average recovery was 100.7%, 100.8%, 101.0%, and RSD was 1.26%, 1.44%, 1.86%, respectively. Conclusion The method is simple and accurate, which can be used for quality control of Fufang Buwu Syrup.

Objective To investigate the characteristics of the executive function and working memory in patients with mild cognitive impairment (MCI), and the relations between working memory and executive function and the effects of working memory on patient' s daily functioning.Methods Thirty patients with MCI and 30 healthy elderly subjects were tested with a wide neuropsychoingical battery of tests including those of executive function, working memory and other cognition domain tests.Executive function was evaluated by using the verbal fluency test (VFT), color trail test (CTT), digital span (DS).Results The results showed the presence of significant executive function and working memory impairment in MCI patients as compared with the healthy controls.The scores of executive function test in MCI patients were decreased significantly in CTT (130.8±58.2 vs 52.0±13.5), CTT-B (210.2±81.8 vs 121.0±33.4),DS (3.4±0.9 vs 4.2±1.1), VFT (8.9±5.4 vs 16.4±5.4) and visuo-objective working memory (0.73±0.12 vs 0.85±9.18) respectively (t = 7.108, 5.159,-2.544,-4.879, and-4.351, all P <0.01 or P < 0.05) .In the stepwise liner regression analysis objective working memory test made a significant independent contribution to ADL (β =-0.720, t =-3.571, P < 0.01).Conclusion The patients with MCI have the deficit in executive function and working memory.Visuo-objective working memory is closely correlated with general cognitive function such as daily function, resulting in daily function decline.
