?AlM: To study the correlation between monocular mild myopic juvenile myopia degree and dominant eye.
? METHODS: Totally 158 patients with juvenile monocularly mild myopia in our hospital from December 2012 to December 2013 were retrospectively analyzed, and cylindrical mirror astigmatism was used for spherical equivalent conversion. On the basis of the myopic degree, they were divided into three groups, 30 cases in group A (-0. 25~-0. 75D), 92 cases in B group (-1. 0~-2. 0D), 36 cases in group C (-2. 25 ~ -3. 0D). The card hole method was selected to measure dominant eye for subjectsat nearly 33cm and 5m. After glasses correction of ametropia, the far and near dominant eyes were received measurement again.
?RESULTS:The monocular mild myopia of dominant eye was compared with the non-dominant eye adjustment function, and there was no significant difference ( P>0. 05 ) . The dominant eye, non - dominant eye mean diopter and other correlations of eyes in the three groups were compared, and there was no significant difference (P>0. 05). The dominant eye of three groups at 5m was compared, and there was significant difference (P<0. 05). The dominant eye of three groups at 33cm was compared, and there was significant difference (P<0. 05). Dominant eye at different visual distance was compared, and there was significant difference (P<0. 05). Monocular uncorrected eye was compared with dominant eye mild afte myopia glassesr, and there was significant difference (P< 0. 05).
?CONCLUSlON: The formation of myopic anisometropia is related to the degree of clearly seeing objects, although glasses correction can improve the clarity and visual, but affect the choice of the dominant eye, because the myopic anisometropia appears most early in the dominant eye, therefore optician correction stage, which should be taken into consideration, and avoid the severity of the adolescent myopia.

Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.

OBJECTIVETo study the effect of sophoridine against bone cancer pain in bone cancer pain model rats induced by W256 tumor cells and its mechanism.

METHODThe rat model of bone cancer pain was reproduced by injecting W256 tumor cells into the rat marrow cavity. Ten days after the model establishment, 36 rats were selected and randomly divided into the model control group and the sophoridine treated group. At the same time, other 10 rats with sham-operation were selected to be the normal control group. Since the 15th day after the operation, rats in the treated group had been given sophoridine (25 mg x kg(-1)) for 10 days. The mechanical withdrawal threshold and the thermal withdrawal latency of each group were measured before and after the treatment. After the last treatment, the radiological and histopathological observation shall be conducted for sick legs of all rats. The expressions of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in tumor tissues were detected by mmunohistochemistry.

RESULTSophoridine could significantly increase the mechanical withdrawal threshold and the thermal withdrawal latency (P < 0.05, P < 0.01), significantly relief the bone injury caused by W256 tumor cells (P < 0.05), and notably down-regulate the COX-2 and VEGF expressions in tumor tissues (P < 0.05).

CONCLUSIONSSophoridine has the effect in relieving pain and inhibiting tumor progression in bone cancer pain rats induced by W256 tumor cells. Its mechanism may be related to the down-regulated expressions of COX-2 and VEGF.

ObjectiveTo explore the clinical and epidemiological value of semi-quantitative regional cerebral blood flow(rCBF)imaging in children with school phobia. Methods A total of 20 cases diagnosed with school phobia were examined with rCBF.Twelve were males and the other 8 were females.The mean age was(14.2?2.1)years(11-18 years).Semi-quantitative analysis methods were used to investigate the correlations among gender,age and rCBF. ResultsThere were significant differences in the rCBF of right fronto-parietal lobe,right occipital lobe,caput and putamen,left thalamus and hippocampus,and temporo-occipital lobe between males and females(P0.05).Only the PI of left temporo-parietal lobe of those ≥ 15 years old was significantly different from that of those

Objective To explore the optimal cut-off points of body mass index(BMI),percentage of body fat(PBF) and body fat mass index(BFMI) for identification of cardiovascular risk factors clustering among elderly males. MethodsThe data of physical examinations from 1 052 Shanghai elderly males in 2007 were collected.The relationship between cardiovascular risk factors clustering and different strata of BMI,PBF and BFMI was analyzed.Receiver Operator Characteristic(ROC) curve analysis was employed to determine the optimal cut-points for identification of cardiovascular risk factors clustering,and area under curve(AUC) was worked out.The population attributable risk proportion(PARP) of risk factors clustering was calculated. Results Odds ratios of risk factors clustering tended to increase with BMI,PBF and BFMI.BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 were the cut-off points that had approximate sensitivity and specificity,and/or had the shortest distance in ROC curve.AUC of all the three indexes was larger than 0.5.Analysis of PARP indicated that BMI under 24 kg/m2,PBF under 21% and BFMI under 5 kg/m2 could prevent 27.1%,37.44% and 36.63% risk factors clustering,respectively. Conclusion BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 can well reflect the cardiovascular risk factors clustering among elderly males.

OBJECTIVETo analyze micromovement of distal tihiofihular joints in different motion range of ankle joint ,and define the micromovement characteristic and range of distal tibiofihular joints.

METHODSTwelve normal Chinese were chosen. There were 9 males and 3 females, aged from 19 to 37 years old with an average (26.5 +/- 0.5) years. Detection terminals of laser photographic scanner were installed near the highest point between medial malleolus and lateral malleolos, the change of detection terminals on the position of dorsiflex, extension, introversion and eversion of ankle joint were scanned by 3D-laser scanner.

Objective: To observe the effect of electroacupuncture (EA) pretreatment on the protein expression of c-fos in fastigial nucleus (FN) and lateral hypothalamus area (LHA) in rats with acute myocardial ischemia-reperfusion injury (MIRI), and to explore the role and mechanism of FN and LHA in EA at the Heart Meridian fighting against acute MIRI reaction. Methods: Seventy Sprague-Dawley rats were randomly divided into a sham operation group, a model group, an EA-Heart Meridian group and an EA-Lung Meridian group, with 14 rats in each group; an LHA lesion plus EA-Heart Meridian group (LHA+EA-Heart Meridian group) and a FN lesion plus EA-Heart Meridian group (FN+EA-Heart Meridian group), with 7 rats in each group. Except the sham operation group, the left anterior descending branch of coronary artery was ligated to establish acute MIRI rat models in the other 5 groups. In the three groups with EA-Heart Meridian treatment, Shenmen (HT 7) and Tongli (HT 5) were selected; Taiyuan (LU 9) and Lieque (LU 7) were selected in the EA-Lung Meridian group. All the EA groups received EA stimulation prior to modeling, with 1 mA in current intensity and 2 Hz in frequency, 20 min each time, once a day for a total of 7 d. The sham operation group and the model group did not receive EA stimulation. The electrocardiogram was observed in the rats to analyze the ST-segment deviation and cardiac arrhythmia score. The expression of c-fos protein in FN and LHA was detected by immunohistochemistry method. Results: Compared with the sham operation group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in the FN and LHA increased significantly in the model group (all P<0.05). Compared with the model group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in FN and LHA decreased significantly in the EA-Heart Meridian group (all P<0.05). Compared with the EA-Heart Meridian group, the ST-segment deviation and cardiac arrhythmia score increased significantly in the EA-Lung Meridian group, LHA+EA-Heart Meridian group and FN+EA-Heart Meridian group (all P<0.05); the expression of c-fos in FN increased significantly in the EA-Lung Meridian group and LHA+EA-Heart Meridian group (both P<0.05); the expression of c-fos in LHA increased significantly in the EA-Lung Meridian group and FN+EA-Heart Meridian group (both P<0.05). Conclusion: FN and LHA are involved in the mechanism of EA at Heart Meridian to improve the acute MIRI reactions, and the cerebellum may participate in the improvement of cardiac function by EA through the cerebellum-hypothalamus projection.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.
