Colorectal liver metastases (CRLM) are one of the main causes of death among the patients with colorectal cancer,yet most patients with CRLM are unable to get radical resection.Fortunately,thermal ablation can yield long-term survival efficacy in this population of CRLM patients.Currently,thermal ablation is the first-line treatment among other ablation technologies,including radiofrequency ablation and microwave ablation (MWA).However,recent advancements in microwave ablation techniques increase consideration of this method in the treatment of CRLM,such as:reliable,fast,efficient and rarely affected by heat-sink effect.This article aims to review the mechanism,efficacy,complications of MWA in treating CRLM.

Objective To investigate the expression and significance of Insulin like growth factor-ⅡmRNA binding protein3 (IMP3) in gastrointestinal stromal tumors (GIST). Methods One hundred and fifteen cases of GIST were subjected to immunohistochemical staining for IMP3 (SP method) and ki67 (iVisionTM method ). The relationship between IMP3 expression with clinicopathologic parameters and Ki67 proliferation indexes were analyzed. In situ hybridization detection of IMP3 mRNA was performed in 20 cases of GIST positive. Results The expression rate of IMP3 was 56.2%(65/115) in GIST positive. A significant correlation can be found between IMP3 expression and tumor of infiltration , coagulative necrosis , metastasis , nuclear atypia , diameter , mitotic count , risk grade of NIH (P < 0.05), while there was no significant correlation between IMP3 and gender, age, primary location, categories of cell type (P>0.05). There was positive correlation of IMP3 expression and Ki67 labeling indexes by Spearman analysis. Positive expression with IMP3 can be observed in 3 cases of recurrence.It may play important role in invasive and development and may be an important factor of prognosis in GIST.

OBJECTIVE Xingnaojing injection(XNJ)is an extracts of Angong Niuhuang Pill that is a well-known traditional Chinese medicine used for the treatment of septicemia and stroke.This study aims to investigate the effect of XNJ on intestinal mucosal barrier in septicemia and intracerebral hem-orrhage(ICH)mice models.METHODS The septicemia mice models were induced by intravenous in-jection with lipopolysaccharide(20 mg·kg-1).And the ICH mice models were made by intrastriatal injec-tion of bacterial collagenase. The septicemia animals were treated intravenously with XNJ at dose of 2.5,5,10,or 15 mL·kg-1.The ICH animals were treated intravenously with XNJ at dose of 10 mL·kg-1. Thereafter, the permeability of intestinal mucosa was assayed by FITC-D method. RESULTS Com-pared with the control group(44.72±4.30),the permeability of intestinal mucosa in the mice in septice-mia group (233.68±28.18) was significantly increased (P<0.01). Treatment with XNJ at dose of 5, 10, and 15 mL·kg-1reduced the permeability of intestinal mucosa (150.45 ± 17.52,139.21 ± 17.05,132.55 ± 18.88,respectively, P<0.01)except 2.5mL·kg-1(240.71±21.42,P>0.01);Compared with sham group (57.88±7.31),the permeability of intestinal mucosa in the mice of ICH(282.25±23.78)was significantly in-creased(P<0.01). Treatment with XNJ (10 mL·kg-1)in the mice of ICH group ameliorated the change of permeability in intestinal mucosa (148.83±15.86, P<0.01). CONCLUSION XNJ exhibits the protec-tive effect on the intestinal mucosal barrier in septicemia and ICH, which will prevent the endotoxin to penetrate the intestinal mucosa and then to enter the circulation in infections and stress.

Objective To evaluate the clinical effects of ultrasound-guided internal jugular vein catheterization in long axis plane,short axis plane and oblique axis plane,in order to identify the opti-mal axis plane for this procedure.Methods One hundred and eighty patients (male 94 cases,female 86 cases,aged 34-82 years)requiring ultrasound-guided internal jugular vein catheterization were in-cluded in this study.They were randomly divided into three groups (n =60 each),long axis group, short axis group and oblique axis group,with 60 cases in each group.The details of catheterization in-cluding the time accessing into vein,the time finishing cannulation,needle redirecting times,number of skin points of puncture,puncture successful rate and complications in the three groups were recor-ded.Results Compared with long axis plane and short axis plane,the oblique axis plane was associat-ed with decreased time for venous access and cannulation.The oblique axis plane also needed less changes of needle direction.The complication of arterial puncture in the oblique axis plane group was significantly lower than long axis plane group and short axis plane group(P <0.05).The number of skin puncture points were similar between the three groups.Conclusion The oblique plane can provide a safe and more effective route to perform the IJV catheterization with minimal risk for carotid artery puncture,which demonstrates the practical superiority over the classic short axis plane and long axis plane for critically ill patients.

Objective To study the distribution patterns of bacterial flora in sigmoid colon tissues and stools in normal population.Method Bacterial flora were identified and analyzed by using 16sDNA sequencing technology in fresh stool samples (n =13) and colon mucosa samples (n =10).Results The diversity and abundance of bacterial flora were significantly larger in the stool samples than in the sigmoid colon samples (P ＜ 0.001,P ＜ 0.001,P =0.042,P =0.006).The consititution of phylum flora between the two groups were same,including flrmicutes,bacteroides,proteobacteria,and actinomycetes.However,the proportions of firmicutes and bacteroides in stool samples were significantly higher than in the sigmoid colon samples,whereas the proportion of proteobacteria was significantly lower (P ＜ 0.001,P =0.025,P ＜ 0.001).At the genus level,faecalibacterium and bacteroides were the dominant flora in feces,whereas pseudomonas,lactococcus,acinetobacter,and flavobacterium were the most common flora in sigmoid colon mucosa.The amounts of bifidobacterium and lactobacillus were low in both two groups.Conclusion The distribution of bacterial flora remarkably differ in stools and sigmoid colon mucosa.

BackgroundThe three-dimensional configuration of the nasolacrimal canal is highly variable with age,gender,and race.But enlargement of the nasolacrimal canal has sparsely been reported in the literature.Objective Computed tomography dacryocystography was performed in patients with unilateral congenital nasolacrimal duct obstruction and normal children to analyze the difference of bilateral nasolacrimal canal.MethodsThis is a retrospective study.Axial scanwith sagittalandcoronalreconstructionwas appliedin computedtomography dacryocystography.Diameters of bilateral nasolacrimal canal of 20 unilateral congenital nasolacrimal duct obstruction patients and 20 normal children were measured.Written informed consent was obtained from each child ' s parents before examination.ResultsThe lacrimal sac,nasolacrimal duct and the peripheral tissue were clearly exhibited by computed tomography dacryocystography.The diameters of the origination,the middle part and the distal end of affected nasolacrimal duct were(5.5±1.4),(5.3±1.2),(5.3±1.6) mm,and normal ones were(3.9±0.8 ),(3.5± 0.8 ),( 3.9± 1.3 ) mm,respectively.These results were statistically significant ( t =5.200,6.967,2.932,P＜ 0.05 ).There was no statistically significant difference in bilateral nasolacrimal canal of normal children (t =0.346,0.281,0.312,P＞0.05 ).Conclusions Computed tomography dacryocystography can image lacrimal passage and their peripheral tissues clearly.The affected nasolacrimal canal diameters of unilateral congenital nasolacrimal duct obstruction were much larger than the fellow sides.The pathogenesis of this phenomenon need much research.

Objective The purpose of this study was to analyze the relation of blood glucose variability and 28-day mortality in patients with different degree sepsis. Methods From September 1, 2010 to September 30, 2012, all adult patients diagnosed with sepsis and treated at least 3 days in Emergency ICU (EICU) of the first affiliated hospital of Kunming Medical University were enrolled in the study. Then the blood glucose levels and the other requisite clinical data were obtained from historical electronic medical records of patients excluding the patients reached exclusive criteria. The maximum and mean of blood glucose, and the glucose variability (the standard deviation,SD of blood glucose) in each patient were calculated. The patients were assigned according to severity of sepsis, then the relationship between SD of blood glucose and 28-day mortality was statistically assessed. Results There was an important correlation between SD of blood glucose and 28-day mortality (OR=4.237, =0.021) . The glucose variability increased with the serious of sepsis ( = 0.016) . Conclusion Glucose variability is an independent predictor of 28-day mortality in septic patients. In addition, the severity of sepsis has a positive correlation with blood glucose variability.
