Chinese Journal of Geriatrics 2012;31(11):935-937
Objective To evaluate the relationship between parameters of MS and prostate volume.Methods A total of 843 men aged 30 to 49 years were enrolled from August 2008 to July 2011.Prostate volume by ultrasonography,serum prostate specific antigen,digital rectal examination,urinary analysis,and MS-related parameters were investigated.We evaluated the correlations of prostate volume with MS and MS components.Results Prostate volume was largerin the MS group (28.3±5.5 ml) than in the non-MS group (23.2±5.6 ml,P<0.05).The prostate volumes in subjects with abnormal levels of fasting plasma glucose (FPG) (25.4±5.5 ml),body mass index (BMI) (25.4±5.3 ml) and waist circumference (30.2±4.8 ml) were increased compared with those of subjects with normal parameters (23.6±5.5 ml,22.6±5.5 and 23.5±5.3 ml,respectively,all P<0.05).The liner regression analysis showed that the FPG,BMI,WC,systolic pressure and triglyceride had a positive correlation with the prostate volume(r=0.216,0.397,0.411,0.170,0.184,respectively; all P<0.05),but negatively related to HDL-C(r=-0.107,P<0.05).Conclusions The patients with abnormal FPG,BMI and waist circumference have larger prostate volume.

4.How to perform the follow-up analysis of visual field test
Ophthalmology in China 1993;0(01):-
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.

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

Hypofractionated conformal radiotherapy is capable to deliver much higher doses to the cancer than is possible with standard techniques. Recently there is data suggesting that the early stage nonsmall cell lung cancer ( NSCLC) which is not suitable to surgery is likely to benefit from this regimen, with low lung toxicity. Manyphase Ⅰ-Ⅱ studies showed that the patients with locally advanced NSCLC are well-tolerated to hypofractionated conformal radiotherapy. The model of radio-physic and relative clinical studies suggest that hy-pofractionation would not increase the risk of radiation pneumonitis compared to standard therapy.

BACKGROUND:Numerous studies have demonstrated various therapeutic methods for cerebrospinal fluid leakage after spinal column surgery, including intraoperative and postoperative measures. Few studies addressed the therapeutic methods of cerebrospinal fluid leakage after cervical vertebra surgery using lumbar subarachnoid catheter drainage.
OBJECTIVE:To evaluate the therapeutic efficacy of sustainable drainage and lumbar subarachnoid catheter drainage for cervical postoperative cerebrospinal fluid leakage.
METHODS:923 patients underwent cervical spine surgery in the Department of Spinal Surgery, the First Affiliated Hospital of Xinjiang Medical University, China from June 2009 to October 2012. There were 24 cases of postoperative cerebrospinal fluid leakage with an incidence of cerebrospinal fluid leakage of 2.6%(24/923). The dural laceration that could not be repaired or be found induced cerebrospinal fluid leakage. Of them, 12 cases received lumbar subarachnoid catheter drainage (catheter group), and 12 cases received sustainable drainage (drainage group).
RESULTS AND CONCLUSION:Compared with the drainage group, the duration of cerebrospinal fluid leakage was significantly shorter in the catheter group (P<0.05). In the catheter group, one case affected cerebrospinal fluid infection. In the drainage group, two cases experienced cerebrospinal fluid cyst and one case suffered from cerebrospinal fluid infection. They were cured by symptomatic treatment. A total of 24 cases were fol owed up for 9-12 months. None of them affected cerebrospinal fluid leakage, cerebrospinal fluid infection or cerebrospinal fluid cyst. Results demonstrated that lumbar subarachnoid catheter drainage in the treatment of cervical postoperative cerebrospinal fluid leakage has a good effect.

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.
