And the paper combined with the experience of the innovation projects in Chinese Academy of Sciences and our institution, and preliminarily expounds the construction connotations and keys of the "flexi-ble management system" in medical scientific research units to provide ideas for enriching the management thoughts of medical scientific research.

Along with the development of science and technology , microwaves are widely used in various fields .Though they have brought much convenience to people , their potential adverse health effects are becoming a concern of governments and researchers .High power microwaves ( HPMs) are widely used in high-tech and new concept weapons , increasing the chance that troops are exposed to HPM environments .It has been clearly confirmed that microwave radiation could cause varying degrees of damage to the nervous system , immune system , cardiovascular system and reproductive system under specific conditions .Therefore , it is of important significance to reduce adverse effects of HPM radiation and improve the combat capability of troops via effective medical protection while doing well in physical protection .According to the mecha-nism and characteristics of microwave radiation damage effects , recent advances in microwave radiation protection are re-viewed in this article , hoping to facilitate research on safer and better drugs .

By establishing a series of Dynamic Cervical Implants (DCI) within C5-C6 cervical spinal segments, the biomechanical finite element analysis for DCI with different width and thickness were carried out to investigate the influence of the width and thickness of DCI's curved section on its equivalent stress and range of motion (ROM), so as to provide some theoretical basis for the optimization of DCI's design. The results show that the width of DCI's curved section has more obvious influence on the ROM of lateral bending and torsion, in comparison with the thickness of DCI's curved section. By appropriate reduction in width, the ROMs of lateral bending and torsion increase obviously, i.e. the overall movement function of patients is improved. Furthermore, the increase of equivalent stress could be counteracted by corresponding increase of thickness.

Objective To observe the therapeutic effect of Ziyin Yangxue Qingre Formula (Formula for enriching yin,nourishing blood and clearing heat) on primary Sjogren's Syndrome (pSS).Methods Totally 64 female pSS patients were randomized into a treating group (33 cases),and a control group (31 cases).The control group was administered Hydroxychloroquine Sulfate Tablet.In addition,the treating group was prescribed Ziyin Yangxue Qingre Formula.Three-month treatment was as one course.After one course of treatment,the changes in symptom scores,salivation quantity,tear quantity,and immuno-infective indices were observed to compare the effect between both groups.Results The total effective rate of the treating group(87.88%) was significantly higher than that (64.52%) of the control group (P

Objective To observe the changes in cytokines, oxygen free radicals, acidulous production in serum and to investigate the effectiveness of monitoring metabolism of cells and the method for evaluating cell injury in patients with severe trauma. Method The detailed data of 117 patients rescued and managed carefully from May 2005 to February 2007 were assessed and stratified with ISS and APACHE Ⅱ , and the serum levels of arterial blood lactate(ABL) ,base deficit(BD) ,superoxide(SOD) ,lipid peroxide(LPO) ,TNF-α and IL-6 were measured in real-time according to the condition of the patient. Results The monitoring biomarkers obviously changed with injury severity which endangered the situation of patients after trauma (P < 0.05) , especially in the patients with ischemia , hypoxia, shock, iniection, SIRS, and MODS (P < 0.01). The persistence of extremely elevated levels of biomarkers meant the organ failure and fatality of patients after trauma, and there was a obvious differece between those cases and cases without elevation of biomarkers ( P < 0.01). Conclusions The outcome of patients after trauma is closely correlated with injury severity,infection and MODS,and the levels of biomarkers including ABL, SOD, IPO, TNF-a and IL-6 are useful indicators of outcome measure.

The transitional near-infrared (NIR) laser was defined as ranging from 1.3μm to 1.4μm, within which the most sensitive tissue to laser damage changed from the retina to the cornea.The ocular damage effect has attracted much attention due to the increased varieties and output power of laser in this spectrum region in recent years.Compared with visible and mid-and-far infrared wavelengths, the ocular damage effect induced by transitional NIR wavelengths has many peculiarities and impact factors due to the bulk absorptionby ocular media.This paper reviews the existing ocular damage threshold data and analyzes the characteristics, impact factors and unresolved issues relating to ocular effects induced by laser radiation over the transition zone.

[Summary] To evaluate the relationships between plasma GPC4 levels and HbA1C . Plasma GPC4 levels were measured in subjects with different glucose tolerances. The relationship between plasma GPC4 levels and HbA1C were studied. Increasing levels of GPC4 showed a significant linear trend and were independently associated with HbA1C . GPC4 levels gradually declined after gradually increased , which is similar with Fins, 2hIns, and AUCinsulin . GPC4 may be involved in the regulation of blood glucose and GPC4 may be regulated by insulin.

ObjectiveTo investigate the effect of vacuum sealing drainage (VSD) with different negative pressures on variation of oxygen partial pressure (PtO2 ) and wound healing in the rabbits.MethodsTwelve rabbit wound models were made and randomly (random number) divided into two groups, namely vacuum group ( n =6 )in which rabbits were treated with VSD by different negative pressures ( - 75 mmHg,- 125 mmHg,- 225 mmHg and - 350 mmHg) for 7 days, and routine treatment group ( n =6). At each interval of measurement, variation of PtO2 was measured by oxygen partial pressure admeasuring device, and area of VSD dressing and surface of wound were measured by vernier caliper, and growth of anaerobic bacteria was detected by bacterial culture, and morphological change and the course of wound healing were observed under by light microscope after HE tissue staining. Meanwhile anther two groups (n =6, in each) were set for comparing, including normal group, sham operation group. ResultsAverage PtO2 value of vacuum group was in the range of ( 1.87 +0. 19) kPa to ( 1.54 ±0. 21 ) kPa which was decreased gradually in 7 days under different negative pressures. Average PtO2 value of routine treatment group and normal group were ( 2. 82 ± 0. 37 ) kPa and ( 5.79 + 0. 50 ) kPa, respectively which weresignificant higher than that in vacuum group ( P ＜ 0. 01 ). PtO2 was fell to 80. 94％ of its original value after VSD for 5 seconds, and continued the downward trend with the increasing of negative pressure at the same interval of measuring. Area of VSD dressing significantly decreased to 65. 36％ of its original area after VDS for5 minutes (P＜0.01). Surface of wound was minimized to 62. 82％ of its original area after VSD for 7 days ( P ＜ 0. 01 ), and variations of those in - 350 mmHg group were significant greater than those in other groups ( P ＜ 0. 01 ). There was no evidence of anaerobic bacteria growth in vacuum group during this experiment. ConclusionsPtO2 could be down-regulated by VSD significantly without growth of anaerobic bacteria, and minimization of VSD dressing at - 350 mmHg was significantly helpful to reduce the area of wound for promoting the healing.
