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.

Background Acute bacterial conjunctivitis is a common ocular infectious disease.It can be cured by topical administration of antibiotics,but these antibiotic eye drops often was used several times per day at present.Azithromycin is thought to offer less using times and shorten the duration of treatment.Objective The purpose of this clinical trail was to evaluate the clinical efficacy and safety of topical administration of 1％azithromycin eye drops for the treatment of acute bacterial conjunctivitis.Methods This study was approved by Ethic Committee of Beijing Tongren Hospital and followed the Declaration of Helsinki.Written informed consent was obtained prior to entering into this trial.A randomized,double-blind and placebo-controlled study was designed.One hundred and eighty patients with acute bacterial conjunctivitis were enrolled in Affiliated Hospital of Qingdao Medical College and Qingdao Municipal Hospital from may,2011 to September,2011.Azithromycin eye drops at the concentration of 1％ was topically administered on 89 eyes of 89 patients twice per day initial and once per day later for 9 days in the trial group,and placebo eye drops was used on 91 eyes of 91 patients in the same way in the control group.The inflammation response of all eyes was examined and scored under the slit lamp microscope,and germiculture was carried out.All adverse responses were assessed during the follow-up.Clinical efficacy was evaluated with the clinical cure rate as the primary indicator and bacterial clearance rate as the secondary indicator.The safety of drug was determined,including the ocular irritation sign,lens transparency and intraocular pressure.The differences of the examining results mentioned-above were compared with Chi Square test.Results One hundred and eighty patients completed the clinical trials according to the program without lost and exclusion cases.The clinical cure rate in 89 subjects in the trial group and 91 control individuals was 76.40％ (68/89) and 43.96％ (40/91),respectively,with significant difference between them (x2=19.73,P＜0.01).The bacterial eradication rate was 85.71％ (24/28) in the trial group and 60.53％ (23/38) in the control group,showing a significant difference (x2 =4.99,P＜0.05).Both 1％ azithromycin eye drops and placebo were well-tolerated with a low incidence of adverse events.Conclusions One percent azithromycin eye drops is effective and safe for the treatment of acute bacterial conjunctivitis with less adverse reaction.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

OBJECTIVETo examine the effects of Han's acupoint and nerve stimulator (HANS) electroacupuncture on the expression of NPY in periaqueductal grey (PAG) of heroin addicted rats.

METHODSHeroin was injected subcutaneously according to the principle of daily increasing dose in rats of experimented group. The ability of special learning and memory were tested by Morris water maze; The expression of NPY in PAG of rat were detected by immunohistochemistry.

RESULTS(1) Escape latency and searching distance in heroin-addiction group were significantly increased compared with those of normal group during the place navigation test (P < 0.05). However, in acupuncture group, escape latency and searching distance was obviously shortened compared with those of heroin-addiction group (P < 0.05). The exploring time and distance of original platform area in proportion to the total distance in heroin-addiction group significantly decreased compared with those of normal group during spatial probe test (P < 0.05). The exploring time and distance of original platform area in proportion to the total distance in acupuncture group was increased compared with those in heroin-addiction group (P < 0.01). (2) The expression of NPY of heroin-addiction group was lower than that in normal group in PAG, while those of acupuncture group was higher than that in the heroin-addiction group (P < 0.05).

CONCLUSIONThe learning and memory induced by heroin-addiction could be reversed and the expression of NPY in PAG was increased by HANS in rats.

This study is to explore whether the Wnt/beta-catenin signaling pathway is involved in the process of tripchlorolide (T4) protecting against oligomeric Abeta(1-42)-induced neuronal apoptosis. Primary cultured cortical neurons were used for the experiments on day 6 or 7. The oligomeric Abeta(1-42) (5 micromol x L(-1) for 24 h) was applied to induce neuronal apoptosis. Prior to treatment with Abeta(1-42) for 24 h, the cultured neurons were pre-incubated with T4 (2.5, 10, and 40 nmol x L(-1)), Wnt3a (Wnt signaling agonists) and Dkk1 (inhibitors) for indicated time. Then the cell viability, neuronal apoptosis, and protein levels of Wnt, glycogen synthase kinase 3beta (GSK3beta), beta-catenin and phospho-beta-catenin were measured by MTT assay, TUNEL staining and Western blotting, respectively. The result demonstrated that oligomeric Abeta(1-42) induced apoptotic neuronal cell death in a time- and dose-dependent manner. Pretreatment with T4 significantly increased the neuronal cell survival and attenuated neuronal apoptosis. Moreover, oligomeric Abeta(1-42)-induced phosphorylation of beta-catenin and GSK3beta was markedly inhibited by T4. Additionally, T4 stabilized cytoplasmic beta-catenin. These results indicate that tripchlorolide protects against the neurotoxicity of Abeta by regulating Wnt/beta-catenin signaling pathway. This may provide insight into the clinical application of tripchlorolide to Alzheimer's disease.

OBJECTIVETo study the relations between anthropometric parameters [body mass index (BMI), percent of body fat, waist circumference] and blood lipids of urban children in Beijing and to compare the ability of prediction effect of waist circumference, percent body fat and BMI on lipid profiles.

METHODS852 children aged 9-10 were recruited with multi-stage sampling. Serum lipids of children were measured using automatic biochemical instrument. Fisher's exact test, trend test and median regression were used to analyze the data from 847 subjects with valid information.

RESULTS(1)With the rise of the BMI, percent body fat and waist circumference, total triglycerides (TG), total cholesterol (TC) and low density lipoprotein choleasterol (LDL-C) showed increasing trends while high density lipoprotein choleasterol (HDL-C) had a decreasing trend(P < 0.01). (2)TG was mainly influenced by waist circumference (t = 6.86), sex (t = 3.96) and percent of body fat (t = 1.85); TC was influenced by percent of body fat (t = 5.31); LDL-C was influenced by waist circumference (t = 4.65), height (t = -2.79) and percent age of body fat (t = 2.77); HDL-C was influenced by waist circumference (t = -12.24), sex (1= -5.83).

CONCLUSIONWith the aggravation of children's fatness (BMI, WC and PBF), serum lipids would increase and WC seemed to be the best predictor for lipids among BMI, WC and PBF.

OBJECTIVETo explore the effect of hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) on the postoperative metastatic rate and survival rate of advanced gastric cancer (AGC).

METHODSIn HIIC group, patients received HIIC (mitomycin C 30 mg and cisplatin 100 mg were added into 2000 ml distilled water, heated to 42 approximately 45 degrees C, perfused to abdominal cavity for 30 min and then sucked) and intravenous chemotherapy after operation (5- FU 10 approximately 15 mg/kg, mitomycin C 0.1 approximately 0.15 mg/kg, adriamycin 0.5 approximately 1 mg/kg i.v drip, once a week for 2 approximately 3 weeks). In control group, patients received intravenous chemotherapy only. The postoperative metastatic rate and survival rate (1- , 3- and 5- year) of patients were compared between 92 cases of AGC undergone HIIC and 120 cases of AGC without HIIC (control group).

RESULTSThe peritoneal recurrence rates after operations occurred within two years were 14.1% and 37.5% in HIIC group and control group respectively (P < 0.01). The 1- , 3- , and 5- year survival rates in HIIC group were 98.9%, 68.5%, and 52.2% and in control group 95.0%, 56.7% and 37.5% respectively. The 3- , and 5- year survival rates were significantly different between the two the groups (P < 0.05).

CONCLUSIONHIIC can kill isolated intraperitoneal cancer cells, reduce peritoneal recurrence rate after operations, raise significantly survival rate of patient, and improve the prognosis of AGC.

Objective To determine the prevalence and risk factors on second-line drug resistance in patients with multidrug resistant tuberculosis (MDR-TB) in Shanghai,China.Methods All pulmonary TB patients with sputum culture positivity detected in Shanghai during January to December,2009,were enrolled.All of the pretreatment sputum-positive cultures samples were tested for routine specimen identification and routine drug susceptibility testing for first-line drugs (Isoniazid,Rrifampin,Ethambutol and Streptomycin).Drug susceptibility testing on second-line anti-TB drugs (Ofloxcin,Amikacin,Kanamycin,Capreomycin,P-aminosalicylic acid and Prothionamide) was routinely performed on isolates of Mycobacterium (M.) TB with MDR.Logistic regression analysis was conducted to determine the risk factors regarding second-line drug resistance.Results A total of 1867 patients infected with M.TB isolates were diagnosed at the TB hospitals/clinics in Shanghai during the study period,of whom 112 (6.0％) were MDR-TB,in which 58 cases (51.8％) showed resistant to at least one of the second-line drugs tested and 10 cases belonged to extensively drug-resistant.In the multivariate analyses,MDR-TB patients who were aged 45-59 years (aOR=4.76,P=0.001 ),with sputum smear positivity (aOR=6.51,P=0.026) were significantly more likely to show resistance to second-line drugs.Conclusion The prevalence of second-line drug resistance among MDR-TB patients was high in Shanghai.MDR-TB patients who were under age of 45-59 years and with sputum smear positivity would represent important common risk factors for the resistance to second-line drugs.
