ObjectiveTo discuss the effect of surgical treatment of varicose vein on primary chronic venous insufficiency(PCVI) in the lower extremities.MethodsBetween August 2007 and August 2008,128PCVIpatients underwenthighligationof the greatsaphenousveinandendovenous electrocoagulation of the varix superficial vein. Spectrum Doppler ultrasound was used to measure the superficial femoral vein blood flow hemodynamic information beneath the first pair of valve including quiet breathing condition and the Valsalva action (reflux time、caliber、reflux velocity). Reflux index (RI) was used as guide line.ResultsClinical sympotoms improved in 54 out of 60 mild PCVI cases, in 29 of 45 moderate PCVI patients, while only in 6 out 23 cases in whom severe preoperative clinical symptom with PCVI was present.The effective rate respectively was 90％, 64％, and 30％.The mild reflux index significantly improved than that before operation ( t = 21. 484, P = 0. 000 ), the moderate reflux index improved than that before operation ( t = 2. 173, P = 0. 035 ), while the serious reflux index were not statistically improved than that before operation( t = 1. 888, P = 0. 078 ). In all cases reflux index improved after the surgery ( x2 = 8. 266,P = 0. 004).ConclusionsMinimally invasive surgical treatment of varicose veins can improve the reflux of the deep vein in PCVI cases with mild to moderate clinical symptom.

Objective To study the killing effect of focused ultrasound activated-hematoporphyrin on H-22 and its optimum exposure time.Methods The distribution of hematoporphyrin in H-22 cells was measured by a fluorescence photometer,the uhrastructure changes were evaluated at different time with a scanning electron micro- scope after treatment with focused ultrasound at the frequency of 1.43 MHz and intensity of 1.0 W/cm~2, 2.0 W/cm~2,3.0 W/cm~2,respectively,in combination with HpD.Results The concentration of HpD in the H-22 cells reached its peak after being added to H-22 tumor cells for 45 minutes,which will produce the hest anti-tumor effect when activated by ultrasound.Morphological observation showed that HpD alone had a slight influence on H-22 cells;ULtrasound alone showed an anti-tumor effect on tumor cells,which was dosage-dependent.Ultrasound dia- thermy in combination with HpD has more effective in terms of its antitumor effect when compared with uhrasound dia- thermy alone.Conclusion The killing effect on H-22 tumor cells of sonodynamic treatment was dependent on the intensity of uhrasound and the content of HpD in the cells,as well as on the time of action of both uhrasound and HpD.

Vibrio parahaemolyticus has been considered as one of the most important foodborne bacterial pathogens.The loop-mediated isothermal amplification(LAMP) that amplifies DNA with high specificity and rapidity under an isothermal condition was applied for rapid detection of this pathogen for the first time.A set of four primers,two outer and two inner primers,was designed specifically to recognize the thermolabile hemolysin gene(tlh) of V.parahaemolyticus.The LAMP reaction mix was optimized.The most optimal reaction temperature and time of the LAMP assay for the tlh gene were 60℃ and 60min,respectively.Genomic DNAs from 28 bacterial strains including 14 V.parahaemolyticus strains were amplified using LAMP,and no amplicon was observed in other bacterial strains.The detection limit of this LAMP assay was around 90 fg of V.parahaemolyticus genomic DNA and 24 colonies forming units for pure cultures.In addition,this method was applied to detect artificially contaminated food samples,and the detection limit was 89 cfu/g for non-cultured artificially contaminated food samples.These results suggested that detection of V.parahaemolyticus by LAMP is an effective and low-cost procedure with high specificity and sensitivity that requires no specialized equipment.This assay is expected to become a valuable tool for rapid detection and identification of V.parahaemolyticus.

AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

Chronic intermitted hypoxia including sleep breathing disorder leads to brain injury. This study explores the potential therapeutic effects of grape seed proanthocyanidin as a neuroprotective agent. A rat model of chronic intermittent hypoxia was employed, and the animals were given low or high doses of grape seed proanthocyanidin. The ultrastructure changes in the brain, the biochemical components, and the animal behavior were examined. The results showed that with hypoxia exposure, neuronal mitochondria exhibited injuries at ultrastructural level, with increased malondialdehyde (MDA) content and reduced superoxide dismutase (SOD) activity. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining revealed increased cell apoptosis in hippocampus. In Morris water maze the animals showed decreased learning abilities, when compared to normal control. The administration of grape seed proanthocyanidin treatment reversed all these observed changes, and improved the learning behavior. We concluded that grape seed proanthocyanidin could alleviate the brain injury caused by hypoxia from sleep breathing disorder.
