In the course of follow-up analyses of visual field test,it should take more than two visual field tests that had similar results as baseline test,and some factors should be taken into account,such as accordant testing conditions,reliable indeces,test errors and fluctuation effects,and so on.The indeces of Mean Deviation(MD)and Pattern Standard Deviation(PSD)could reflect the whole change trend of follow-up visual field test,while sensitivity value of every point and their pattern deviations could help to analyse tiny changes of visual field tests.Those statistic softwares provided by automatic perimetry should be used adequately.Through the follow-up analyses of visual field test,glaucoma doctors could adjust therapy schemes in time in order to obtain objective intraocular pressure and stabilize visual field and glaucoma.

Abstract? AlM: To observe the effect of combining partial reduction orthokeratology ( Ortho-K ) and spectacles on slowing myopic progressionin high myopic adolescent.? METHODS: Sixty - nine eyes of 36 high myopic adolescent ( aged 9 ~15 years ) with spherical equivalent refraction ≧-6. 00 diopters ( D) ( spherical component≧-5. 50D) were fitted with custom-made four-zone/five-curve Ortho-K lenses. The target of reduction was to achieve -5. 00D for both eyes. The residual refractive errors after at least one month of Ortho-K wear were corrected with single-vision spectacles for clear vision in the daytime. The unaided visual acuity ( UVA) , refractive error ( RE ) , axial length ( AL ) , and ocular health were assessed before the Ortho-K lens wear, and followed up for 2a after Ortho-K.?RESULTS: ( 1 ) Changes in UVA: The mean UVA was 0. 09±0. 05 at baseline before Ortho-K;the mean UVA was 0. 27 ± 0. 14, 0. 54 ± 0. 18, 0. 78 ± 0. 24, and 0. 81 ± 0. 19, respectively after Ortho-K wear for l night, 1wk, 1, and 3mo. The differences of UVA were significant with baseline (P<0. 05), and became stable 1mo after the treatment. (2) Changes in RE:The mean RE was -6. 82± 0. 71D at baseline before Ortho-K and -6. 86 ± 0. 77D after Ortho-K wear for 1a (P>0. 05 compared to baseline). The mean RE was-7. 11±0. 81D after Ortho-K wear for 2a, and the amount of myopia increased -0. 29 ± 0. 37D compared to baseline (P<0. 05). (3) Changes in AL: The mean AL was 26. 18 ± 0. 57mm at baseline before Ortho-K, and it was not significantly different (P>0. 05) from the AL after Ortho-K wear for 6mo (26. 19±0. 54mm) and for 1a (26. 21± 0. 47mm). The AL was 26. 37±0. 59mm after Ortho-K wear for 2a, and the mean increase was 0. 19 ± 0. 28mm compared to baseline (P<0. 05). (4) Grade 1 corneal staining was observed in some subjects at each visit. However, the staining was improved after lens cleaning, discontinuing lens wear, or applying artificial tears. No other adverse events were reported in all subjects during the 2a study.?CONCLUSlON:Combining partial reduction Ortho-K and spectacles completely slowed myopic progression in high myopic adolescent after receiving the treatment for 1a, and partially reduced myopia progression after 2a of treatment. No severe ocular complications were found throughout the treatment. The combination treatment appeared to be effective and safe, but its long-term effect needs to be further assessed.

Recently a number of acupuncture clinical trial projects mainly conducted by conventional scientists have generated many negative results. A large meta-analysis of patient-level acupuncture data for the treatment of chronic pain conditions have demonstrated that the effects of verum acupuncture on pain improvement have statistically significant, but small, differences compared with sham-acupuncture procedures and no difference between acupuncture points and non-points. These conclusions have puzzled the acupuncture community and made confusion for acupuncture research and practices. The purpose of this paper was to compare differences between acupuncture clinical practices and the trial studies, which include "acupuncture technical principles", "acupuncture clinical trial design", and "acupuncture practice based on the theory of traditional Chinese medicine". These factors contribute to the puzzle between the acupuncture community/practice and acupuncture clinical trials, which can be improved in future studies.

BACKGROUND: Previous studies demonstrated that adventitia fibroblasts exhibit important role in the hyperplasia of newly born endomembrane after blood vessel injury. However, the mechanism regarding phenotypic transition of adventitia fibroblasts in vitro remains unclear. OBJECTIVE: To observe effect of peroxisome proliferators-activated receptor ?agonist (PPAR ?) on phenotypic transition of adventitia fibroblasts induced by transforming growth factor ?1 (TGF-?1) in vitro, as well as the expression of collagen protein Ⅰ. DESIGN, TIME AND SETTING: A randomized grouping control experiment was performed at the Tissue Engineering Laboratory of Ninth Affiliated Hospital of Shanghai Jiao Tong Medical College between July 2007 and October 2008. MATERIALS: The aorta thoracica's adventitial fibroblasts were cultured from Sprague Dawley rats, with 2-month-old, weighing 120 g. The TGF-?1 was supplied by American GenWay Biotech Company. The rosiglitazone power was purchased from Beijing Comens Chemical Co., Ltd. METHODS: The experiment was divided into 3 groups: In the TGF-?1 group, fibroblasts was induced with TGF-?1 with different concentrations (3, 5, 10, 15 ?g/L) for 48 hours; in the rosiglitazone group, fibroblasts was induced with rosiglitazone (5, 10, 30, 50 ?mol/L) for 45 minutes followed by co-culture with 10 ?g/L TGF-?1 for 48 hours. There was no intervention measure in the control group. MAIN OUTCOME MEASURES: The phenotypic transition of fibroblasts was measured by ?-smooth muscle actin, the expression of smooth muscle ? 2-actin, as well as collagen type Ⅰ was determined by protein immunoblotting. RESULTS: Compared with the control group, 5 ?g/L TGF-?1 could significantly stimulate the changes of phenotypic transition of fibroblasts as well as the expression of smooth muscle ?2-actin and collagen type Ⅰ, which reach a peak level when treated with 10 ?g/L TGF-?1 (P 0.05). Compared with control group, 30 ?mol/L rosiglitazone could significantly inhibit changes of phenotypic transition of fibroblasts as well as the expression of smooth muscle ? 2-actin and collagen type Ⅰ(P

Objective: To understand the gambling relations between the stakeholders of catastrophic medical insurance policy under New Rural Cooperative Medical System ( NCMS) , and provide theoretical references for the smooth operation of catastrophic medical insurance policy of NCMS. Methods:Analyzing the game relationships among the four sides:the government, business insurance agencies, designated medical institutions and participating farmers suffering from catastrophic diseases through game theory. Results: The government and business insurance agency, and the government and designated medical institution belong to cooperative games. The farmers participated in catastrophic medical insurance tend to choose cooperative strategy. Non-cooperative games exist in business insurance agency, designated medical institution and participating farmers. Conclusion: Strategic relationship of close cooperation should be established between the business insurance agencies and designated medical institutions. The government should strengthen the regulatory constraints between the business insurance agencies and designated medical institutionsi, at the same time, it needs to establish the incentive mechanism soon.

Objective To observe the protective effect of goserelin on ovarian function of premenopausal patients with breast cancer during chemotherapy. Methods Forty patients with breast cancer under 40 received adjuvant chemotherapy were randomly divided intotest group(20 cases) and control group (20 cases). Compared the recovery rate and time of menstruation between two groups. Results All the 40 patients finished the treatment. Recovery ratio of normal ovarian function in test group and control group was 75% and 50% (P =0.013) respectively, and the median menstrual recovery time in two groups was 4.65 months and 6.65 months (P = 0.046) respectively. Statistically significant differences were found between two groups. Conclusion Goserelin can effectively protect ovarian function during chemotherapy , increase the ratio of normal ovarian function, shorten menstrual recovery time, and shows good tolerance.
