OBJECTIVETo compare the effectiveness of percutaneous microwave ablation ( MWA) versus hepatectomy for multifocal hepatocellular carcinoma.

METHODSFrom August 2002 to March 2012, one hundred and twenty-two patients with multifocal hepatocellular carcinoma (diameters 1 to 7 cm, 2 to 4 lesions) were treated by either complete MWA or radical hepatectomy, and their clinical data were collected and analyzed.The patients were divided into MWA group (n = 50) and resection group (n = 72), and the resection group was matched by MWA group based on clinical parameters. The survival and complications in the two groups were compared.

RESULTSThe overall 1-, 3- and 5-year survival rates were 100.0%, 73.0% and 62.0%, respectively, in the MWA group, and 80.0%, 56.0%, and 41.0%, respectively, in the resection group (P < 0.05). The corresponding recurrence-free survival rates were 88.0%, 63.0%, and 52.0% in the MWA group, and 68.0%, 45.0%, and 36.0%, respectively, in the resection group (P< 0.05). The multivariate Cox regression analysis indicated that albumin level, performance status, treatment modality, and tumor size were independent prognostic factors.

CONCLUSIONCompared with hepatectomy, percutaneous microwave ablation is a minimally invasive and reproducible procedure, and can improve the survival in patients with multifocal hepatocellular carcinoma.

Objective To detect the influence of rapamycin on the expression of 4 kinds of miRNAs and the effect cell autophagy.To study the relationship of miR-144 and Beclin-1 gene.Methods SKOV-3 cells were treated with 50 ng/mL rapamycin 2 hours and 10 nmol/L 3-methyl adenine 12 hours,the expression of miR-17,miR-20a,miR-144 and miR-155 was detected by RT-qPCR in SKOV-3 cell of different groups,the protein expression of Beclin-1 was detected by Western blot.The targeting effect of miR-144 on Beclin-1 gene was verified by the dual-luciferase reporter assay,Western blot and RT-qPCR.Results The expression of miR-17,miR-144 and miR-155 were in creased compared with NC groups in rapamycin group (P＜0.05);miR-17,miR-20a and miR-144 were down regulated compared with NC group in 3-MA group(P＜0.05);the protein of Beclin-1 was down expression compared with NC group in rapamycin group.miR-144 could suppress Beclin-1 expression by targeting the specific 3'untranslated region sequence of Beclin-1 gene.Conclusions miR-144 can inhibit the autophagy-related gene Beclin-1 expression and regulate the autophagy process in SKOV-3 cells.

Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P＜0.001; LM: t = 9. 346, P＜0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.

Background Many methods are widely studied to improve the therapeutic effect of trabeculectomy for glaucoma,and the clinical effectiveness of the amniotic membrane application during trabeculectomy is one of the research hotspots.Objective This study was to evaluate the efficacy and safety between trabeculectomy with (TE-AMT) and without amniotic membrane transplantation (TE-noAMT) for treating glaucoma.Methods Articles published from 1965 to December 2010 were searched from The Cochrane Library,PubMed,EMBASE,CNKI,Chinese Biomedicine Database,internet by computer,and manual search then was performed according to the predetermined strategy.Randomized controlled trials (RCT) on TE-AMT and TE-noAMT were included.The quality of included articles were scored based on Jadad table,and the relative parameters and information were extracted,including author,design of the trials,country,number of eyes and patients,gender,follow-up duration,age,classification of glaucoma,baseline IOP and loss rate.The main analysis indicators were the percentage of IOP reduction,completely operative successful rate,qualified success rate and adverse events.The pooled estimates were carried out with RevMan version 5.0 software.Results Nineteen RCTs documents were reviewed by meta-analysis with the Jaded scores ≥3 in 2 papers and ＜3 in 17 papers.Total 977 eyes of 818 patients were included.The weighted mean differences (WMD) of the percentage of IOP from baseline were (WMD =8.47％,95％ CI:5.20-11.75) at 6 months and (WMD=9.37％,95％ CI:4.97-13.77) at 12 months postoperatively.Relative risk (RR) of complete success rate and qualified success rate at postoperative 6 months were (1.40,95％ CI:1.19-1.65) and (0.47,95％ CI:0.22-1.00),respectively.RR values of adverse event such as shallow anterior chamber,hyphema,hypotony and choroidal detachment,failed filtering blebs at 6,12 months were 0.51 (95 ％ CI:0.30-0.85),0.43 (95％ CI:0.20-0.92),0.51(95％CI:0.26-1.00) and 0.57(95％CI:0.14-2.31),0.31(95％CI:0.20-0.47),0.31 (95％ CI:0.17-0.55),respectively.Conclusions TE-AMT appears to have better efficacy in lowering IOP,increasing complete success rate and reducing adverse event I in comparison with TE-noAMT.

Objective To investigate the clinical characteristics,surgical indications and methods of children sylvian cistern arachnoid cysts complicated with subdural hematoma.Methods Fifty childhood cases of sylvian cistern arachnoid cyst complicated with subdural hematoma were retrospectively analyzed,who were all surgically treated in the First Affiliated Hospital of China Medical University from July 2005 to August 2015.Among them,20 childhood cases were subacute subdural hematoma,30 childhood cases were chronic subdural hematoma.All patients underwent microscopic cyst excision,cystocistern fenestration plus hematoma removal surgery.During the surgery,firstly we resected the cyst wall tissue as far as possible,and then we communicated the cyst with subarachnoid space and cisterns,which could make the cerebrospinal fluid flowed unobstructedly.Results The course of every operation was smooth,and there was no severe complication postoperatively.Original symptoms and imaging manifestation resolved or improved in all patients.During a mean follow-up period of 5.7 years,there were no recurrent cases.Conclusion Children sylvian cistern arachnoid cyst can induce subdural hematoma.In this situation,microscopic cyst excision,cystocistern fenestration plus hematoma removal surgery is safe and effective.
