Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

Objective To determine the efficacy of glucose-loweringtreatment by proton magnetic resonance spectroscopy (1H-MRS).Methods Bilateral frontal lobes of 45 male patients with type 2 diabetes mellitus (T2DM) underwent 1 H-MRS separately bythe time it was first diagnosed.Among them,30 were treated with insulin,15 were rejected.The bilateral frontal lobes of all patients were re-examined with 1 H-MRS after 6 months.The ratios of metabolites in the frontal lobe were recorded and compared,and observing whether the lactate(Lac) peak appeared or not.Results Significantly higher values of the N-acetylaspartate (NAA)/creatine (Cr)ratio and NAA/choline (Cho) ratio after 6 months (2.414 2± 0.206 6 and 2.244 2±0.341 5) were found in bilateral frontal lobes compared with pre-therapy (1.905 3±0.135 7 and 1.906 0±0.322 1)(P＜0.05).Significantly lower values of the NAA/Cr ratio and NAA/Cho ratio in the refuse treatment group(1.504 2 ± 0.262 4 and 1.510 0± 0.220 8) were found in bilateral frontal lobes compared with pre therapy (1.960 0±0.175 0 and 1.880 8±0.297 0)(P＜0.05).Lac peak was not detected in the all experiments.Conclusion 1 H-MRS provides valuable information in the assessment and evaluation of clinical efficacy and prognosis of T2DM by detecting the changes of brain metabolism.

OBJECTIVE: To test cathepsin L as a biomarker of myocardial ischemia by examination of cathepsin L expression in plasma after myocardial ischemia and ischemia-reperfusion in rats. METHODS: The rat models were established and divided in acute myocardial ischemia model (myocardial ischemia 30 min, 1 h, 2 h groups), ischemia-reperfusion model (ischemia-reperfusion group), and isoflurane-pretreated ischemia-reperfusion model (isoflurane-pretreated group), respectively. Normal control group and sham-operated group were established as contrast. The contents of cathepsin L in plasma were examined by ELISA and myocardial infarction areas were measured after TTC staining. RESULTS: No statistical significant changes were found among the experimental groups compared with the normal control group and sham-operated group (P>0.05). The cathepsin L from the ischemia-reperfusion group increased to 2.37 times compared with the normal control group (P<0.05). The cathepsin L and myocardium infarction size of isoflurane-pretreated group decreased compared with the ischemia-reperfusion group (P<0.05). CONCLUSION The cathepsin L in plasma is not a promising biomarker of acute myocardial ischemia. Isoflurane preconditioning can reduce the cathepsin L in plasma caused by ischemia-reperfusion injury.

Astragalus polysaccharides was lounded to 4-(2-aminoethylphenol), followed by labeling the APS-Tyr with fluorescein-5-isothiocyanate (FITC) at the secondary amino group. The absorption enhancement effects of low molecular weight chitosan and protamine on astragalus polysaccharides were evaluated via Caco-2 cell culture model. The results show that the fluorecent labeling compound has good stability and high sensitivity. On the other hand low molecular weight chitosan and protamine also can promoted absorption of the astragalus polysaccharides without any cytotoxity, and the absorption increase was more significant with increasing the amount of low molecular weight chitosan and protamine. At the same time, the low molecular weight chitosan has slightly better effect. The transepithelial electric resistance (TEER) of Caco-2 cells show that absorption enhancers could improve its membrane transport permeability by opening tight junctions between cells and increasing the cell membrane fluidity.

Objective　To determine the sensitivity and specificity of using the computer-photoscreener and non-cycloplegic retinoscopy in the detection of amblyopiogenic factors in nine to fifty months old infants.Methods　Three hundred children whose ages range from nine to fifty months were screened with the computer-photoscreener and non-cycloplegic retinoscopy. With a masked standardized clinical assessment as the standard, an overall comparison of the results obtained with the two techniques revealed a sensitivity and specificity. Photoscreen images on the computer monitor screen were reviewed and analyzed immediately by two independent observers for indicators of amblyopiogenic risk factors. Simultaneously, the results were compared to the findings of a full ophthalmologic examination.Results　The computer-photoscreener revealed a sensitivity of 94.2% and specificity of 90.1%, and the non-cycloplegic retinocopy revealed a sensitivity of 85.7% and specificity of 81.1% for the detection of amblyopiogenic risk factors, including hyperopia (+2.75 D or more), myopia (-1.50 D or more), astigmatism (2.00 D or more),anisometropia (2.00 D or more), ocular misalignment (5 degrees or more), and media opacity (1.5mm or more). Conclusion　The computer-photoscreener offers an opportunity to identify problems that limit vision, and could provide a feasible and sufficiently reliable screening technique in infants and preschool children who can be screened successfully for amblyopiogenic risk factors.

Objective To investigate the surgical strategy of recurrent rectuvaginal fistula. Methods Retrospectivly analyzed the clinical data of 13 patients with recurrent rectovaginal fistula from December 2001 to December 2008. The etiopathogenisis and the ways of treatment were analyzed. Results All the 13 patients with a transverse colostomy surgical repaired with Mason operation in the secondary intention,and recepted closure of colostomy in the third intention for treatment, all patients were cured. No recurrent fistula was identified with postoperative follow-up 4 - 84 months.
