Objective To determine whether isometric handgrip exercise can increase collateral flow to the ischemic myocardium in acute coronary occlusion patients with coronary artery disease (CAD).Methods Sixty-five patients with one-vessel CAD were randomly assigned to either an isometric exercise (IME) group or no-exercise (NE) group.Patients in the IME group performed isometric handgrip exercises (50％ of the maximum voluntary contraction) during 1 min of coronary balloon occlusion.Patients in the NE group remained sedentary during the procedure.The collateral flow index (CFI),heart rare (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were determined prior to and at the end of 1 min of coronary occlusion.Results In the IME group the average CFI improved significantly more during the occlusion than in the NE group.The differences in HR,SBP and DBP were also significantly grcatcr in the CFI group than in the NE group controls.Conclusion Isometric exercise can induce significantly increased coronary collateral flow in CAD patients during acute vessel occlusion.

Objective To investigate whether functional electrical stimulation (FES) can improve the expression of proteins in the NMDAR1-pGLuR1 pathway so as to promote the recovery of motor function and sensation after stroke.Methods Eighty-one Wistar rats were used to make a photochemical brain model of local ischemia.Rats were randomly assigned into a sham, placebo stimulation or FES group.Rats in the placebo and FES groups had local ischemia induced in the M1 zone of the brain using the photosensitive dye Bengal rose.It was administered intravenously and a laser beam was then stereotactically positioned on the skull.The rats in the FES groups were stimulated for 30 minutes (10 minutes on, 10 minutes off, then 10 minutes on).The placebo group's treatment was similar, but without the electric current.The rats in the sham group received no intervention.The cylinder test and the adhesive-removal test were used to test the rats' motor function and sensation before the operation and before they were sacrificed.Cohorts were sacrificed after 3, 7 and 14 days of intervention.NMDA receptor and AMPA receptor were detected in the peri-ischemic cortex using western blotting.Results After 7 and 14 days the index of forelimb motor function in the cylinder test of the FES group was significantly better than that of the placebo group.The average adhesive-removal time of the FES group was also significantly faster compared with the placebo group.After 7 days the average expression of NMDAR1 in the FES group was significantly higher than in the placebo group.The average expression of GluR1 and pGluR1 in the FES group was significantly higher than in the placebo group after 14 days.Conclusion Functional electrical stimulation can improve motor function after ischemia through the NMDARAMPAR signal pathway, at least in rats.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

AlM:To compare the effect of different incision in corneal astigmatism after phacoemulsification.
METHODS: Totally 88 cases ( 122 eyes ) with pure cataract were randomly divided into two groups. Forty cases (60 eyes) were clarity corneal incision in group A, and 48 cases ( 62 eyes ) were sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism ( SlA ) , uncorrected visual acuity ( UCVA ) and best correct vision acuity ( BCVA ) were observed in pre- and post-operation at 1d;1wk;1mo.
RESULTS: The mean astigmatism had statistically significant difference between two groups at 1d; 1wk;1mo after operation(P<0. 05). The SlA had statistically significant difference at 1d ( P<0. 05 ); The SlA had no statistically significant difference between two groups at 1mo after operation (P>0. 05). UCVA≥0. 5 and BCVA≥0. 8 had statistically significant difference at 1d; 1wk ( P<0. 05) . There had no statistically significant difference at 1mo after operation (P>0. 05).
CONCLUSlON: Phacoemulsification with scleral tunnel incision remove combined intraocular lens ( lOL ) implantation has small changes to corneal astigmatism. By selecting personalized corneal incision according to the corneal topography might be more beneficial.

Purpose To investigate the diagnostic value of high-resolution CT reconstruction techniques on the same slice in hypertrophy of transverse process of the fifth lumbar vertebra (HTPL5V), and to provide a basis for clinical diagnosis and treatment. Materials and Methods Twenty-two cases of clinically diagnosed HTPL5V and 20 normal adults were examined with GE LightSpeed 16-slice spiral CT (36 cases) and Philips iCT 256-slice (6 cases). L5 transverse process and the fifth lumber nerve were reconstructed and observed on the workstations. Results In 22 cases of HTPL5V, there were 26 pseudarthrosis formation and 2 sides with L5 transverse process touching the sacral ala. In 28 sides the iffth lumber nerve traveled through false foramina of the HTPL5V including 6 cases of bilateral compression and 16 cases of unilateral compression. In 21 cases, the nerve was compressed by hyperosteogeny on 27 sides (96.4%) and 1 side due to stenosis (3.6%). On 25 sides (89.3%) the compressed nerves were curved in shaper. There was bulging and/or herniated lumbar disc on 9 sides in 7 cases (32.1%). Conclusion High-resolution CT reconstruction techniques can demonstrate the iffth lumbar nerve of HTPL5V and provide evidence for clinical diagnosis and treatment.
