Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

Objective To detect the expression of Cancer-Testis antigen NY-ESO-1 in human laryngeal squamous carcinoma (LSC) and to explore its significance in immunotherapeutic application. Methods The expressions of NY-ESO-1 protein in the LSC and in the pathologically positive lymph nodes were detected by PV-9000 Immunohistochemistry. Western blotting was also employed to measure the expressions of NY-ESO-1 in the tumor core region(TC), the tissues at the sites of 0.5cm, 1.0cm away from LSC periphery and the distant normal larynx tissues. Results NY-ESO-1 protein expression was positive in 30 out of 69 (43.48 %) cases of LSC. The expression level of NY-ESO-1 protein were found to significantly decrease by tums in TC and corresponding adjacent tissues (P ＜0.01). None of the nine normal larynx tissues expressed NY-ESO-1 protein.It did not display an obvious correlation between the expression of NY-ESO-1 with T staging, pathological grading and lymph node metastasis (P ＞0.05). Its positive expression was found in pathologically positive cervical lymph nodes, which were significantly lower than that in the primary site (P ＜0.05). Conclusion NY-ESO-1 protein express at high level in human laryngeal squamous carcinoma, and they may play a role in genesis and development of tumors, which suggests that NY-ESO-1 gene might be used as target antigens for immunotherapy of LSC and the further research is necessary.

Objective To summaize the experience of application of direct digital radiography and electrohydraulic shockwave lithotripsy in treatment of residual bile duct stones.Methods A retrospective analysis of clinical records of 60 patients with residual bile duct stones treated in our hospital from 2003 to 2006 was made.Results In 59(95.9%) of 60 cases the stones were removed completely,including successful removal in one time of application of this method in 57 Patients(95.0 %),and 2 applications in 2 Patients ﹙3.3 %).One case with bile duct stone complicated with dile duct cancer was unsuccessful.The biggest stone was 3.5 cm?2.5 cm?2.0 cm.No serious complications occurred and changed to operation.The 59 cases were followed up for 6 mo to l yr,and all had a successful outcome.Conclusions The method of combination of direct digital radiography and electrohydraulic shockwave lithotripsy in treatment of postoperative residual bile duct stones after operation can facilitate removal of residual bile duct stones.The procedure is a safe way of treating residual stones.

Objective To study the effect of fluorine on the bone histomorphometry of humbar in rats.Methods Ninety 2-month-old SPF Sparague-Dawley rats,half male and female,were randomly divided into 9 groups:control[(childhood(CS),adult(AS),long-time(NS)]group and drug group[childhood high-fluoride and low-fluoride group(CHS,CLS),adult high-fluoride and low-fluoride(AHS,ALS),long-term high-fluoride and low-fluoride(CLHS,CLLS)].The control group was administered orally with solution of 0.9%NaCl,while the drug group was given orally with different dose of NaF at the same time.

The long-term administration of NaF on rats does not increase the bone formation of rats in growth period. The osteoblast activities as well as the bone absorption of lumbar vertebra were strengthened. The likelihood of bone fracture became larger. The negative effects on bone metabolism and bone quality of rats were gradually displayed along with the prolongation of sodium fluoride usage.

Objective:To analyze morphological character of lateral tibial plateau fracture fragment, and its correlation to the presence of a meniscus injury in tibial plateau fractures.Methods:A total of 79 consecutive patients of the simple lateral tibial plateau fractures from July 201 1 to July 2015 were inclu-ded in this study,with 65 males and 14 females with an average age of (34.3 ±7.2)years and 22-61 years.According to Schatzker classification,21 cases were of Type Ⅰ,41 cases Type Ⅱ,and 17 cases Type Ⅲ.The characteristics of lateral tibial plateau fractures were evaluated by plain X-ray and magnetic resonance imaging (MRI ).The type and severity of meniscus injury were diagnosed by MRI scan. Three-dimensional measurements of the lateral fragment width (LFW),the lateral plateau depression (LPD),the coronal angulation of lateral fragment (CALF),and tibial plateau widening (TPW)were measured with Picture Archiving and Communication Systems(PACS)software.The patients with and without meniscus injuries were divided into different groups and analyzed respectively.Comparison of the above measurements between the two groups was analyzed by independent t test.Results:In all the 79 lateral tibial plateau fracture patients,26 cases (32.9%)of meniscus injuries were detected by MRI. Among all the meniscus injury cases,3 were of SchatzkerⅠ,16 SchatzkerⅡ,and 7 SchatzkerⅢ.In meniscus intact group,the average LFW was (22.0 ±2.8)mm while in meniscus injury group it was (21.3 ±3.3)mm (t =-1.008,P =0.317).The average LPD of non meniscus injury group was (5.4 ±2.8)mm,while in meniscus injury group was (8.7 ±2.8)mm (t=4.98,P=0.001).The average CALF of the two groups were 9.1°±6.1°and 10.6°±7.1°,and there was no significant dif-ference between the two groups (t=0.38,P=0.831).The average TPW was (3.0 ±1.1)mm,and (4.8 ±1 .7 )mm of the two groups.There were significant differences between the two groups (t =5.216,P=0.001).Conclusion:There was no obvious correlation between the LFD and meniscus inju-ry.The CALF of lateral tibial plateau fracture had no significant correlation with meniscus injury either. The degree of LPD and TPW may indicate injury of the meniscus in tibial plateau fractures.
