To investigate the efficacy of acupuncture plus rehabilitation exercise in treating post-apoplectic dysphagia. Methods:The patients were randomly allocated into treatment and control groups. The treatment group was treated by acupuncturing points Fengchi(GB 20),Tianzhu(BL 10),Tongli(HT 5) and Lianquan(CV 23) plus rehabilitation exercises and the control group only by rehabilitation exercise. Results:The total effective rate was 95.0% in the treatment group and 71.9% in the control group. There was a significant difference between the two groups (P＜0.01). Conclusion:Acupuncture plus rehabilitation exercise can improve the curative effect on postapoplectic dysphagia.

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.

Aiming at local field potential, the present paper introduces a method of estimating lag of neuron activities between brain areas based on windowed Harmonic wavelet transform (WHWT). Firstly, the WHWT of signals of two brain areas are calculated. Secondly, the instantaneous amplitude of the signals is calculated and finally, these amplitudes are cross-correlated and the lag at which the cross-correlation peak occurs is determined as the lag of neurons activities. Comparing with amplitude cross-correlation based on Gabor wavelet transform (GWT) or Hilbert transform (HT), this method is more precise and efficient in estimating the directionality and lag.
