Objective To compare the costs and effectiveness between the laparoscopic cholecystectomy (LC) and the open cholecystectomy (OC). Methods Clinical data of 97 patients treated either by LC (n=41) or OC (n=56) were retrospectively reviewed. Results The hospital stay, postoperative hospital stay, hospitalization expenditure and medical incomes in Group LC and Group OC were (11.4?3.0) days and (15.1?4.2) days (t=-4.811,P=0.000), (6.1?0.9) days and (10.7?2.4) days (t=-11.673,P=0.000), (8 723.8?1 077.2) yuan and (6 423.4?1 398.4) yuan (t=8.791, P=0.000), (6 236.4?591.0) yuan and (3 426.6?683.2) yuan (t=21.162,P=0.000), respectively. There were no statistical significances between the two groups in preoperative hospital stays and occurrences of complications (t=1.684, P=0.095;?2=0.434,P=0.510). Conclusions Compared with the OC, health resources were more properly utilized but costs were higher in the LC.

Objective To investigate the cortex gray matter configuration in amnestic mild cognitive impairment(aMCI)patients using MRI technology, FMRIB software library(FSL)and Freesurfer software.Methods Twenty aMCI patients and 20 normal control subjects were recruited and studied. They were matched by age, sex and education. All the patients and healthy volunteers underwent MRI scan using SEMENTS trio 3.0 T MRI. The subtile three-dimensional brain images were obtained using high resolution scanning technique. The imaging data was processed and analyzed with FSL and Freesurfer software. The cortex gray matter density and thickness in different brain areas of aMCI patients and normal control subjects were calculated and compared using statistic analysis. Results Compared to that in the controls, cortex gray matter density in the aMCI patients showed remarkable decreases in left frontal lobe, temporal lobe,parietal lobe, and slight decrease in right thalamus, temporal lobe and island lobe; For cortex thickness,aMCI patients showed significant decreases in left anterior cingulate gyrus((2. 19 ±0. 24)mm), inferior parietal lobe((2. 27 ± 0. 15)mm), bilateral parahippocampal gyrus((2. 03 ± 0. 15),(2. 04 ±0. 17)mm), precentral gyrus((2. 20 ± 0. 11),(2. 31 ± 0. 19)mm), postcentral gyrus((1.88 ± 0. 11),(1.82 ± 0. 09)mm), superior frontal gyrus((2. 42 ± 0. 34),(2. 40 ± 0. 28)mm), middle frontal gyrus ((2.31±0.31),(2.33 ±0.29)mm), supramarginal gyrus((2.53 ±0.33),(2.55 ±0.23)mm),temporal pole((3.41 ±0.68),(3.30 ±0.56)mm)and transverse temporal gyrus((2.04 ±0. 12),(2. 01 ± 0. 11)mm; t = 2. 13-3.75, P ＜ 0. 05), no significant changes in the other areas(t = 0. 09-1.88, P ＞ 0. 05). Conclusions Our results suggest that there are significant changes in gray matter configuration in cortex of aMCl patients. The changes of cortical thickness is earlier than the changes of gray matter density.

Good clinical practice should be based on evidence. Evidence quality should be based on critical appraisal in evidence based medicine (EBM). Evaluation of evidence quality plays an important role in evidence level clarifying, which is the core of EBM. Different recommendations for clinical practice often derive from evidence levels. Thus evidence quality evaluation is the first and most important step in EBM. There are lots of standards to evaluate evidence quality in the world. However there are two aspects of the evaluation, one is methodological evaluation and the other is reporting evaluation. This article collected a series of standards for clinical trials quality evaluation according to different research designs. It is hoped that the resource and introduction about the quality evaluation of clinical trials be helpful for medical researchers in China. Only being familiar with all kinds of standards of methodology and reporting, researchers could publish high quality scientific papers.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.

METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.

RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).

CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.

Objective:To observe the expression of microRNA (miRNA, miR) -7850 in renal cancer tissues, and to explore the effect of miR-7850 on the proliferation and migration of renal cancer cells and on the regulation of serine proteinase inhibitor B3 (SERPINB3) gene expression.Methods:Real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-7850 in renal cancer tissues and renal cancer cell lines. The renal cell carcinoma cell line with the lowest expression of miR-7850 was selected, and the negative control sequence (miR-NC) and miR-7850 mimics were transfected into renal cell carcinoma cells by Lipofectamine 2000 transfection reagent, respectively, which were defined as miR-NC group and miR-7850 group. qRT-PCR was used to detect the expression of miR-7850 in transfected renal cancer cells. The cell proliferation and migration ability after transfection were detected by cell counting kit-8 (CCK-8) method and transwell experiment. Bioinformatics prediction and dual luciferase reporter gene experiments were used to verify the target gene of miR-7850. qRT-PCR and Western blot were used to detect the expression of target genes in renal cancer cells after transfection.Results:Compared with adjacent tissues (5.95±0.44), the expression of miR-7850 in kidney cancer tissues (1.19±0.33) was lower ( P<0.01). Compared with immortalized proximal renal tubular epithelial cells (1.01±0.07), the expression of miR-7850 was lower in renal cancer cell lines ( P<0.05), and the lowest in A498 cells (0.13±0.01) ( P<0.01). The expression of miR-7850 in the miR-7850 group (7.46±0.93) was significantly higher than that in the miR-NC group (1.01±0.08) ( P<0.01), indicating successful transfection. Compared with the miR-NC group, the cell proliferation ability of the miR-7850 group was significantly reduced ( P<0.05). The number of migrating cells in miR-NC group and miR-7850 group were (139.50±12.31) and (75.09±16.05) cells, respectively, and the cell migration ability in miR-7850 group decreased significantly ( P<0.01). Bioinformatics technology shows that the target gene of miR-7850 was SERPINB3. The dual luciferase reporter gene experiment confirmed that miR-7850 can target the SERPINB3 gene ( P<0.05). Compared with the miR-NC group, the expression of SERPINB3 in cells of miR-7850 group was significantly reduced ( P<0.05), as well as the CDK4, CyclinD, Snail and Vimentin. Conclusions:miR-7850 is lowly expressed in renal cancer tissues and cell lines. miR-7850 can inhibit the proliferation and migration of renal cancer A498 cells, which may be related to its inhibition of SERPINB3 gene expression.
