ObjectiveTo investigate the effects of mefformin on the levels of serum retinol-binding protein 4 (RBP-4),high sensitive C reactive protein (hs-CRP) and tumor necrosis factorα (TNF-α) in patients with impaired glucose tolerance(IGT) and metabolic syndrome(MS). MethodsSixty patients with IGT and MS were divided into mefformin treatment group (30 cases) and life-style intervention group (30 cases) by random digits table. Body mass index (BMI),the levels of HbAic, HOMA-IR, blood fat, RBP-4,hs-CRP, TNF- α were measured both before and 16 weeks after treatment in the two groups and compared.ResultsThe levels of HbA1c, HOMA-IR, RBP-4, hs-CRP and TNF- α were significantly lower in mefformin treatment group than those in life-style intervention group [(5.09 + 0.26 )% vs. (5.69 ± 0.49 )%, 2.95 ± 0.63vs. 3.49 ± 0.78, ( 18.69 ± 6.50) mg/L vs.(26.20 ± 6.97) mg/L, (2.37 ± 0.53) mg/L vs.(2.99 ± 0.57) mg/L,(9.49 ± 2.37) μ g/L vs. ( 14.33 ± 2.62) μ g/L] (P < 0.01 ). The results of multiple linear regression showed that correlations were found between the changes of RBP-4 and BMI,HOMA-IR,hs-CRP,TNF-α(β =0.284,0.506,0.274,0.230,P <0.01 ),and HOMA-IR was the most important limiting factor. Conclusions Mefformin can improve insulin sensitivity of the patients with IGT and MS, and depress the levels of RBP-4,hs-CRP and TNF- α. Meanwhile mefformin has anti-inflammatory effect.

OBJECTIVEIncidence and severity of motion sickness (MS) in hot-humid environment are extremely high. We tried to know the effect of two-stage training for reducing incidence and severity of ms.
METHODSSixty male subjects were divided into experimental group and control group randomly. Subjects in experimental group received: (2) adaptation training including sitting, walking and running in hot lab. After adaptation confirmation based on subjective feeling, rectal temperature, heart rate, blood Pressure, sweat rates and sweat salt concentration, we tested both groups by Coriolis acceleration revolving chair test and recorded Graybiel's score and grading of severity to evaluate whether adaptation training was useful; (2) Anti-dizzy training 3m later of deacclimatization contained revolving chair training for 10 times. Then we did the same test as mentioned above to evaluate effect of anti-dizzy training. RESULST: Graybiel' s score and grading of severity had no difference between two groups through acclimatization training (P > 0.05). While they had difference through anti-dizzy training (P < 0.01).
CONCLUSIONAdaptation training seems useless for reducing incidence and severity of MS in hot-humid environment, but anti-dizzy training is useful.

Six years' English teaching in department of obstetrics and gynecology in Wenzhou Medical College were reviewed. Language and cultural differences are the main reasons hindering teaching quality. Rational use of a variety of teachers,preparing for lessons adequately,adoption of English image data,supplying and revising English teaching materials,using network auxiliary teaching and forming ef-fective education mode are conducive to improving English teaching quality in department of obstetrics and gynecology for foreign students.

Objective To investigate the effects of δ-opioid receptor agonist DADLE (D-Ala2-D-Leu5-enkephalin) on the hemodynamics and oxygen metabolism in rats with sepsis. Methods Eighty healthy male SD rats were randomly divided into 4 groups ( n = 20 each) : sham operation group (group S), sepsis group (group SEP) ,DADLE, group and DADLE2, group. Sepsis was induced by cecum ligation and puncture (CLP) in SEP, DADLE,and DADLE2 groups. In DADLE1 and DADLE2 groups, 0.5 mg/ml DADLE 10 mg/kg was injected intraperitoneally (IP) 0.5 h before CLP and immediately after CLP respectively. Mean arterial pressure (MAP), left ventricular systolic pressure (LVSP) and ± dp/dtmax were recorded at 0, 2, 4 and 6 h after CLP (T1-4). Blood samples from left common carotid artery and right external jugular vein were collected at T4 for blood gas analysis. The cardiac index (CI), O2 delivery (DO2), O2 consumption (VO2) and O2 extraction rate (ERO2) were calculated.Results Compared with group S, MAP and LVSP were significantly increased at T2, while decreased at T3,4, and ± dp/dtmax was significantly increased in group SEP, MAP was significantly increased at T2, while decreased at T3,4, LVSP was significantly increased at T2,3, while decreased at T4 , and ± dp/dtmax was significantly increased in DADLE, and DADLE2 groups, and CI, DO2 and VO2 were significantly decreased and ERO2 was increased in SEP, DADLE, and DADLE2 groups (P<0.05). Compared with group SEP, MAP, LVSP and ± dp/dtmax at T3,4 and CI, DO2 and VO2 were significantly increased, while ERO2 was significantly decreased in DADLE1 and DADLE2 groups (P < 0.05). There was no significant difference in the parameters mentioned above between DADLE1 and DADLE2 groups ( P > 0.05). Conclusion δ-opioid receptor agonist DADLE can obviously improve the hemodynamics and oxygen metabolism in septic rats.

Background Image clarity during near work is influenced by several factors,such as accommodative lag,pupil size and monochromatic aberrations.Since image clarity during extended reading at near distance has been cited as a possible inducement of myopia in childhood and a possible difference between myopic and emmetropic people throughout life,it is important to examine these factors in myopic and emmetropic myopic juvenile during reading at near distance. Objective The aim of this study was to investigate the relationships among wavefront aberrations,accommodative response and pupil size in early onset and progressive myopes eyes under the different reading status and explore the possible mechanism of the development of myopia as well. Methods Fiflyseven subjects aged from 12 to 16 years were enrolled and grouped as emmetropes,the onset of myopes and progressive myopes.Reading material were Chinese novels presented by rapid serial visual presentation at a distance of 25 cm. Accommodative response and pupil size were recorded by a Grand Seiko WV-500 autorefractor.The Image J software was used to calculate the pupil diameter.Wavefront aberrations were then measured with a WASCA wavefront analyzer. Results Aberrations and accommodative response showed large inter-subjeet variability.With accommodative stimulus of 4 diopter,the accommodative lag in the early-onset of myopes group and progressive myopes group were ( 1.72 ±0. 53) D and ( 1.74 ±0. 44) D, showing larger value in comparison with ( 0. 96 ±0. 55) D of emmetropes group( t=4.25 ,t=4.47 ,P<0. 001). However,there were no significant differences in accommodative lag between the early-onset of myopes group and progressive myopes group( t = 0. 18, P>0. 05). The mean value of pupil diameter, total RMS value, high-order RMS value, spherical aberration and coma were all significantly reduced with the stimulus varied from 0 D to 4 D( P<0. 01). However,none of the pupil sizs,total RMS value,high-order RMS value,spherical aberration and coma had significant difference among different refractive groups( P>0. 05). Conclusion The early-onset of myopes and progressive myopes had larger accommodative lag. The lower sensitivity to defocus at near reading distance,inducing the larger accommodative lag and hyperopic defocus may be linked to the developing myopia.

Objective To investigate the rat bone structural changes of lower limb following lumbar nerve dorsal roots section.Methods Forty-eight mature female Wistar rats were divided into posterior radi- cotomy(PR)and comtrol groups randomly.The bilateral femoral bone mineral density(BMD)and biome- chanics characteristics were analyzed 2,4 and 8 weeks after the radicotomy.The same operation except the radicotomy was done in the sham group.Results In PR group,2,4,and 8 weeks after the radicotomy,the BMD of femur was(0.221?0.008)g/cm~3,(0.213?0.015)g/cm~3 ,and(0.216?0.105)g/cm~3 ,respective- ly;while that was(0.223?0.005)g/cm~3,(0.218?0.014)g/cm~3 ,and(0.208?0.111)g/cm~3 in control group.No significant difference was observed between the two groups(P>0.05).In PR group,2,4,and 8 weeks after the operation,the mean maximum load in three-point bending test of femun midshaft was(93.64?8.76)N,(89.77?11.18)N and(93.21?8.74)N,respectively,and was lower than the values of the con- trol group at the same time point(95.94?6.29)N,(91.63?9.43)N,(95.57?8.64)N,However,there was no significant difference between the two groups(P>0.05).Accordingly,there was no significant difference in the energy absorption in femun midshaft between the two groups(P>0.05).Conclusion The selective rhizotomies of part lumbar never dorsal roots might not cause the loss of the femur BMD and the change of bio- mechanics property significantly in short period.
