AIM:To compare the difference between diopter of refration measured after cycloplegic mydriasis with retinoscopy and hand-held autorefractor so as to explore the feasibility of using hand - held autorefractor for refraction screening in cadet candidates.
METHODS:Respectively using hand-held autorefractor and streak retinoscope to do optometry examination in 317 cadet candidates students ( 634 eyes ) after mydriasis. Main index of refraction values ( spherical, cylindrical mirror degree and axial) were analyzed by difference test and correlation analysis. And the elimination rate was comparatively analyzed.
RESULTS: Diopters of sphere and cyclic refraction measured by hand-held autorefration were significantly higher than those by retinoscopy ( P< 0. 05 ), but the correction analysis showed that there was high correlation (r=0. 733, 0. 694), axial of refration measured by these two methods were non - significant ( P > 0. 05 ). The disqualifying rate using autorefraction was much higher than that using retinoscopy. It was easy to be wrongly eliminated.
CONCLUSION:Because of the high correlation between diopters of autorefraction measured by retinascopy and autorefractor, autorefraction has application value in refraction screening in cadet candidates with normal vision.

Objective To investigate the autonomic modulation and influence during myocardial ischemia based on analysis on heart rate dynamics with heart rate variability(HRV). Methods From 13 free download ECG records in long-term ST-T(LTST)database, 193 ischemia episodes were extracted for analysis, and 5 min intervals before and after each selected isehemia episode were selected as control ones. Using symbolic dynamic analysis method, the indexes during different stages were calculated. The repeated measurement analysis of variance was introduced for statistic test. And the distribution of autonomic reflex mode to isehemia duration was analyzed by linear fitting. Results Symbolic analysis detected an increase in the percentage of non-varlable patterns (0 V%) and a decrease in the percentage of very variable patterns(2 UV%), indicating a more sympathetic predominance compared with the baseline. But the trend of the shift in autonomic balance towards sympathetic predominance reduced with the extension of ischemic duration, suggesting a possible protection for heart. Conclusion Symbolic dynamic analysis is capable of identifying changes in autonomic modulation and seems appropriate for elucidating the neural pathophysiological mechanisms occurring in myocardial ischemic episodes.

[Objective]Through the clinical investigation of the conversative treatment of undisplaced femoral necks,to analyze the occurrence of secondary displacement and femoral head necrosis.[Method]The medical records of 216 patients with undisplaced femoral neck fractures who were primarily treated conservatively from January,2000 to January,2004 were analyzed.Among that,186 cases is in accordance with the selected standard,which were consisted of 82 men and 104 women.(the average age 67.5).One hundred and forty-one fractures were given to bed rest in rotation-proof shoes,and walking on the crutches was followed after four weeks.Forty-five patients began to get out of bed with double crutches on the third day.When displacement happened,the operation was carried out.Once X-rays showed the fracture line unclearly,it is considered as bone healing.The early stage of femoral head necrosis was defined by sclerotic region or cyst in the femoral head.[Result]Sixty-eight fractures(36.6%) united and secondary considered displacement occurred in 118 cases(63.4%); the average time was 16 days (2～68 d) after injury when the displacement is found.In all primary healing patients,femoral head necrosis rate was 25%.The discovery time of necrosis was between 4 and 18 months,the most was 36 cases in the interval of 6 to 12 months.As for patients of secondary displacement,92 for closed reduction and hollow screws fixation,and the head necrosis happened in 55 patients(59.8%).The discovery time was from 4 to 18 months,the most in 6 to 12 months was 36 cases.The operation of open reduction and internal fixation with hollow screws was in 26 cases,73% of necrosis rate for it.The time was range from 3 to 12 months,11 case was the most in the period of 3 to 6 months.[Conclusion]Undispalced femoral neck fractures treated conservatively bear higher risk of secondary displacement and femoral head necrosis.In addition with more mortality and general complications,we therefore recommend primary operative stabilization of undisplaced femoral neck fractures.

Objective:Small bowel IRI models in rats were established to explore the effect of glutamine enriched parenteral nutrition on mucosal barrier,and to discuss the probable mechanisms.Methods:Thirty Wistar rats were randomly assigned into 3 groups:The control group(N group,n=10) ,conducted fictitious operation and fed with common forage,TPN group(n=10) and TPN+Glu group(n=10) .The morphous of mucous,serum and intestinal mucosal Gln concentration,levels of D-lactate,endotoxin,TNF-?,IL-6,HO-1 positive ratio and HO-1 mRNA were detected.Results:Glutamine obviously improved the structure of intestinal mucosal and decreased the expressions of D-lactate,endotoxin,TNF-?and IL-6.And enhanced the expressions of HO-1 mRNA and HO-1.Conclusion:Glutamine enriched parenteral nutrition can alleviate small intestinal IRI and inflammatory reaction and enhance the HO-1 and HO-1 mRNA expressions.HO-1 and its metabolin's anti-oxygen,anti-apoptosis,anti-inflammator action may be the mechanism of the protective action of Gln on mucosal barrier of small bowel.

Objective:To obverse the therapeutic effect of superficial needling with different frequencies for intractable facial paralysis. Methods: A total of 120 patients with intractable peripheral facial paralysis were allocated into a superficial needling with high frequency group (150 times/min), a moderate frequency group (100 times/min) and a low frequency group (50 times/min) according to the random number table method. The Toronto facial grading system (TFGS) was used to evaluate facial nerve functions before treatment and after 2 weeks and 4 weeks of treatment respectively. The electromyography (EMG) test of the mandibular branch of facial nerve was used to compare the motor nerve conduction velocity (MCV), sensory nerve conduction velocity (SCV) and monophasic action potential (MAP) among different groups, and was done before treatment and after 4 weeks of treatment. The clinical efficacy was also compared. Results: After 2 weeks and 4 weeks of treatment, the changes of TFGS scores in the three groups all showed statistical significance (all P＜0.05), and the TFGS score in the low frequency group was substantially higher than that in the other two groups. After treatment, the changes of the MCV and SCV in the three groups all showed statistical significance (all P＜0.05), and the results in the low frequency group were higher than those in the other two groups; the change of MAP in the three groups showed no statistical significance (P＞0.05). The total effective rate was 65.0%, 80.0% and 95.0% in the high frequency group, moderate frequency group and low frequency group respectively, and the between-group differences showed statistical significance (P＜0.05). Conclusion: Compared with the superficial needling with high and moderate frequencies, superficial needling with low frequency can produce more significant clinical efficacy for intractable facial paralysis.

In order to study mechanical stress on root from orthodontic tooth movement by sliding mechanics, a 3-dimensional finite element model incorporating all layers of a human mandibular dental arch with orthodontic appliance has been developed to simulate mechanical stress on root from the orthodontic tooth movement. Simulated orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis was applied to the crown of the teeth. The finite element analysis showed when orthodontic forces were applied to the tooth, the stress was mainly concentrated at the neck of the tooth decreasing uniformly to the apex and crown. The highest stress on the root was 0.621 N/mm(2) for cervical margin of the canine, and 0.114 N/mm(2) for apical region of the canine. The top of canine crown showed the largest amount of displacement (2.417 microm), while the lowest amount of displacement was located at the apical region of canine (0.043 microm). In conclusion, this model might enable one to simulate orthodontic tooth movements clinically. Sliding force at 2 N is ideal to ensure the bodily orthodontic tooth movement. The highest stress concentration in the roots was always localized at the cervical margin when orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis, so there may be the same risk of root resorption when orthodontic force of 2 N at 0, 30 and 45 degree was used in clinic cases.
