1.Minimally invasive technique for potential application in colorectal cancer surgery
Chinese Journal of Clinical Oncology 2016;43(11):464-466
New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

Objective To evaluate the efficacy of superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage. Methods The clinical data of 31 iatrogenic renal hemorrhage patients who had underwent superselective renal artery embolization were retrospectively analyzed. Results All patients were found to have bleeding site by contrast examination, including pseudoaneurysm in 21 cases, renal arteriovenous fistula in 3 cases, extravasation of contrast media in 4 cases, and pseudoaneurysm and renal arteriovenous fistula in 3 cases. Microcoil embolization was used in 20 patients, and microcoil embolization combined with gelatin sponge was used in 12 patients. Thirty patients got successful embolization once, and success rate was 96.8%(30/31). One patient got successful embolization in the second time. There were no serious complications and no recurrence of renal hemorrhage. Conclusions Superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage has the advantages of exact hemostasis, less trauma and fewer complication, and can retain the normal renal tissue maximumly.
3.Intravascular Ultrasound-based Computational Fluid Dynamics Simulation of Arterial Vessel Wall Strain Distribution.
Journal of Biomedical Engineering 2015;32(6):1244-1248
Quantitative measurement of strain distribution of arterial vessel walls due to pulsatile blood flow within the vascular lumen is valuable for evaluating the elasticity of arterial wall and predicting the evolution of plaques. The present paper shows that the three-dimensional (3D) strain distribution are estimated through uni-directional coupling for 3D vessel and blood models reconstructed from intravascular ultrasound (IVUS) images with the computational. fluid dynamics (CFD) numerical simulation technique. The morphology of vessel wall and plaques as well as strain distribution can be visually displayed with pseudo-color coding.

6.THE SYNAPTIC RELATIONSHIPS OF VL NUCLEUS AND CRUCIATE CORTEX OF THE CAT
Acta Anatomica Sinica 1954;0(02):-
The distribution of afferent terminals from VL nucleus to cruciate cortex was studied by using nerve fibers degeneration and electron microscopic technigues. Cortical area 4 could be further divided into three subdivisions according to their geographical relations to the eruciate sulcus: an anterior, a posterior and a lateral zone, respectively. It was demonstrated that the degenerating axon terminals were mainly distributed in anterior and lateral zones. Much less terminals were observed in the posterior zone. Totally 112 terminals were observed in the anterior zone. Among them, 78.6% were seen in layer Ⅲ, 19.6% in layer Ⅰ, 1.8% in layer Ⅴ. Of the 112 terminals found in the lateral zone, 62.5% were distributed in layer Ⅲ, 31.2% in layer Ⅰ and 6.3% in layer Ⅴ. On the other hand, only 33 degenerating terminals were found in posterior zone. their distributions were: 51.6% in layer Ⅰ, 42.4% in layer Ⅲ and 6.0% in layer V. Approximately 75% of the degenerating axon terminals examined in these three zones made synaptie contacts with dendritic spines, and 25% with dendritic shafts. The vast majority of these synapses could be classified as asymmetrical type synapse.In area 6, most of the degenerating terminals were encountered in layer Ⅰ and Ⅲ. All of them formed asymmetrical type synapses with dendritic spines. No degenerating terminals could be found in area 3a.
7.ELECTRON MICROSCOPIC STUDY OF COMMISSURAL AXON TERMINALS IN CAT MOTOR CORTEX
Acta Anatomica Sinica 1954;0(02):-
Synaptic connections of commissural axon terminals from contralateral motor cortex have been studied by using anterograde degeneration and electron microscopy in the cortical area 4? of cat. The results showed that most of the commissural terminals display electron-dense type degeneration, and 92 degenerating terminals were identified in area 4?. The number of terminals in layer Ⅰ was nearly equal to layer Ⅲ. In layer Ⅲ, an asymmetrical synapse formed between a degenerating terminal and the soma of a bipolar cell was observed. In layers Ⅴ-Ⅵ, no degenerating terminal could be found. Among the total degenerating terminals, 77.2% were found to make synapses with dendritic spines, 21.7% made synapses with dendritic shafts and 1.1% with soma, and all of these synapses were of the assymmetrical type.

9.Lipoprotein-associated phospholipase A_2 as a predictor for severity of coronary atherosclerosis
Academic Journal of Second Military Medical University 1981;0(04):-
Objective:To investigate whether plasma lipoprotein-associated phospholipase A_(2)(Lp-PLA_(2)) activity correlates with severity and stability of coronary atherosclerosis and other established cardiovascular risk factors.Methods: Coronary angiography(CAG) was performed in 180 hospitalized patients who were suspected as having coronary heart disease(CHD).The severity of pathological changes of the coronary artery was assessed by the number of diseased coronary branches and Gensini′s score.According to the results of CAG,the 180 patients were divided into 2 groups: CHD group(n=112) and non-CHD group(n=68).The CHD patients were further divided into subgroups according to the clinical types,the number of diseased coronary branches and Gensini′s score.Lp-PLA_(2) activity,white blood cell(WBC) count,high sensitive C reactive protein(hsCRP),lipids,blood pressure and body mass index were measured.The age,sex and prior medical histories including hypertension,diabetes mellitus and smoking status were obtained before CAG in all patients.Lp-PLA_(2),WBC count and hsCRP were compared statistically between the subgroups,and correlation coefficients of Lp-PLA_(2) activity with WBC count,hsCRP and other conventional risk factors for CHD were calculated.Results: Plasma Lp-PLA_(2) activity in CHD patients was significantly higher than that in controls(P
