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 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.

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.

More than ten bacteriophage of E.coli were isolated from the soil and the dung of the fowl-run, then three of named bacteriophage A, C, D which lysis E.coli virulently were selected to investigate biological characterizations. The results showed that high activities were obtained after the phages incubated at 50℃ for 1 h or 60℃ for 30 min. The phages could be alive at the range of pH from 4 to 12, Ca 2+ or Mg 2+ added to the medium could stimulate the lysis of phages. However, the formation of the plaque could be inhibited obviously by adding sodium citrate to the medium.

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.

AIM: To study the effect of torsional mode phacoemulsification on cornea in patient with age-related cataract.METHODS: Totally 161 age-related cataract patients (196 eyes) were assigned randomly to phacoemulsification by torsional mode(Group A) or conventional ultrasound mode (Group B) in our hospital from January 2012 to December 2014.The intraoperative data of effective ultrasound time(UST)and effective cumulative dissipated energy(CDE) were recorded.Postoperative outcomes and the change of the best corrected visual acuity(BCVA),corneal edema degree(CED),central corneal thickness(CCT) and endothelial cell count were also recorded and compared.RESULTS: For grade Ⅰ,Ⅱ,Ⅲ and Ⅳ nuclear density,the mean UST and mean CDE were significantly lower in Group A.The average BCVA of Group A was better than Group B at 1 and 7d after surgery.But at 30d postoperative,there was no statistical difference between these two groups(P>0.05).The corneal clarity and the mean change of central thickness showed significantly less corneal edema in Group A than Group B in 1 and 7d postoperatively.This difference was no longer found significantly at 30d after surgery(P>0.05).At 7 and 30d postoperative,the endothelial cells in Group B were lower than in Group A.CONCLUSION: By reducing the effective UST and CDE intraoperatively,the main effect of torsional mode phacoemulsification on cornea shows less damage to endothelium cells,and patients get better prognosis.But the damage to cornea by torsional mode phacoemulsification isn`t fundamentally solved.

Objective To observe the clinical efficacy of suspended moxibustion plus Chinese medication in treating icteric hepatitis. Method Ninety-two patients with icteric hepatitis were randomized into a treatment group and a control group, 46 in each group. The treatment group was intervened by suspended moxibustion plus oral administration of Chinese medication for supplementing yang, tonifying spleen, expelling dampness, and activating blood circulation;the control group was intervened only by the same Chinese medication. The symptom and sign score, and liver function items including TBil and ALT were observed, and the clinical efficacy was compared. Result The symptom and sign scores were significantly changed in both groups after intervention (P<0.05). After intervention, there was a significant difference in comparing the symptom and sign score between the two groups (P<0.05). The TBil and ALT levels were significantly changed after intervention in both groups (P<0.05). The recovery rate and total effective rate were respectively 87.0%and 95.7%in the treatment group versus 76.1%and 82.6%in the control group, and the inter-group differences were statistically significant (P<0.05). Conclusion Suspended moxibustion plus Chinese medication is an effective method in treating icteric hepatitis.
