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.

Object To study the botanic characteristics of leaves from three plants of Goniothalamus (Bl.) Hook. f. et Thoms. in order to correctly distinguish them from numerous plants of the genus, which are important resource of anticancer medicine.Methods The maceration method and paraffin method were used to study the epidermis and structures of leaves from G. griffithii Hook. f. et Thoms., G. leiocarpus (W. T. Wang) P. T. Li and G. yunnanensis W. T. Wang. Results Three leaves were morphologically similar in the structure, but there were some anatomical differences among them. For example, the absence of druses in the epidermis and the presence of fibrous sclereids in the lamina mesophyll of leaves from G. griffithii, while the presence of druses in epidermis and the absence of fibrous sclereids in lamina mesophyll of the leaves from G. griffithii and G. yunnanensis were observed. In addition, epidermal hairs of G. griffithii were composed of three cells, stomatas were always normal, there were seven oil cells and 25 mucilage cells per mm leaf width in lamina mesophyll and the vascular tissue of the midrib consisting of ten small bundles. However, epidermal hairs of G. yunnanensis were composed of two cells, many abortive stomatas were present at the distal surface, there were only four oil cells and 16 mucilage cells per mm leaf width and the vascular tissue of the midrib consisted of 12 small bundles.Conclusion Three species were easily identified on the basis of epidermal and structural characters of the leaves of them.

Objective To analyze domestic and foreign papers on H5N1 virus research using literature metrology and visualized knowledge mapping.Methods Pajek, Bibexcel,and VoSviewer software were used based on Web of Knowledge platform.Results Study on H5N1 virus has been a research focus wide since 2005 and a series of institutions and investi-gators have appeared, with US being the leader in this area and followed by China.The most popular topics of studies on H5N1 included its virology, epidemiology, basic research, anti-virus drugs and vaccines.Conclusion Studies on H5N1 have received more attention, which suggests that more efforts have to be made in China in terms of communication and co-operation with key institutions and famous researchers so as to achieve more success in key areas.

CT data regarding PUMCⅡ d2 adolescent idiopathic scoliosis obtained from one female patient were input into modeling software minics 11.11 to obtain medical simulation model.Then finite element analysis models of AIS patients (T1-S) were created by introducing simulation models into software abaqus 6.7.Finite element models of T6 11 segments were corrected by 5 different correction methods:simple concave bracing,simple convex pressurization,concave distraction and convex compression simultaneously,concave distraction prior to convex compression and concave distraction after convex pressurization.Abaqus software was used to simulate correction of scoliosis with vertebral arch pedicle screw by loading 50 N,100 N,and 200 N distraction forces on the concave side pedicles of the end vertebrae T6 and T11.The displacement of vertebrae T6 in Y-axis (sagittal plane) and Z-axis (coronal plane),which respectively represented the correction effects of kyphosis and scoliosis,was compared between prior to and after correction.Simple concave distraction provided better outcomes in terms of displacement of T6 in Z-axis than the remaining four methods (P ＜ 0.01).Concave distraction and convex compression simultaneously,concave distraction prior to convex pressurization and concave distraction after convex compression produced identical displacements of T6 in Y-axis,which were all better than simple concave distraction (P＜ 0.01).The present findings imply that for curative effects of five methods on correction of scoliosis in the coronal plane:simple concave distraction＞ concave distraction and convex compression simultaneously = concave distraction prior to convex compressio= concave distraction after convex compression ＞ simple convex pressurization;for curative effects of five methods on correction of kyphosis in the sagittal plane:simple convex compression ＞ concave distraction and convex compression simultaneously = concave distraction prior to convex compression= concave distraction after convex compression＞ simple concave bracing.Simple concave distraction could not produce obvious corrective effects on kyphosis rather than lead to worsened kyphosis to some extent.Simple convex compression could not produce obvious corrective effects on scoliosis rather than result in aggravated scoliosis to some extent.

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.

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.
