Metastasis to liver is the most happened distant metastasis and is the leading cause of death in patients with colorectal cancer.Complete surgical resection of liver metastases from colorectal cancer is major curative method for resectable metasrases.Other methods such as chemotherapy, targeted therapy, hepatic ar-tery intervention, radiotherapy, radiofrequenly ablation or cryo-ablation should be considered.Both systemic and local treatment are.important for liver metastasis from colorectal cancer.

Objective To investigate the clinical role of a combination therapy of percutaneous radiofrequency ablation(RFA) and transcatheter arterial chemoembolization(TACE) in large hepatic tumors. Methods Out of 62 patients with hepatocellular carcinomas confirmed by pathology, 21 patients received a combination therapy of TACE and RFA(combination group), 22 patients TACE therapy alone, and the rest 19 patients RFA therapy alone. A total of 106 tumors with a mean diameter of ( 5.9? 0.7) cm(ranged from 5.0 to 8.1 cm) were detected, and the largest tumor was selected for observation in a patient with multiple lesions. There was no significant difference in mean age, tumor size and liver function grade among the three groups.Results Tumor complete necrosis accounted for 80.9%in combination group, which was significantly higher than that of TACE group and RFA group ( 27.2%, 47.4%,P 0.05). Mean survival duration of combination group was 25.6 months, significantly higher than that of TACE group( 14.9 months)(P0.05). Conclusions Compared with TACE or RFA therapy alone, the combination therapy improves tumor complete necrosis rate and prolongs the patients′ survival duration.

To explore the binocular disparity information for children with a normal vision based on computer-assisted evaluation system.We examined the random dot zero-order disparity,line zero-order disparity,2nd-order disparity and random dot motion parallax for 97 children with normal vision.And 94 children reached 100″ vision disparity both in random dot zero-order disparity and line zero-order disparity (pass rate of 96.9％) ; all 94 cases passed the 2nd-order disparity and random dot motion parallax.Thus children with a normal vision develop their stereopsis.

BACKGROUND:Adipose-derived mesenchymal stem cels have rich sources that are easily obtained, which can be used to treat acute myocardial infarction. OBJECTIVE: To investigate the therapeutic effect of adipose-derived mesenchymal stem cel transplantation on acute myocardial infarction in rats. METHODS:Rat models of acute myocardial infarction were made and subjected to adipose-derived mesenchymal stem cel transplantation in comparison with model and control (sham operation) groups. RESULTS AND CONCLUSION:Echocardiography findings showed significant improvement in the left ventricular end-systolic diameter, left ventricular end-diastolic diameter and ejection fraction in the cel transplantation group compared with the model group (P < 0.05). Hematoxylin-eosin staining showed that myocardial infarction was evident in the model group, in which, there were rarely viable myocardial tissues and few vessels in the infarcted region, but in the cel transplantation group, there were evident survived myocardial tissues and transplanted cels. The percentage of infarct size was significantly lower in the cel transplantation group than the model group (P < 0.05). Immunohistochemical staining showed that adipose-derived mesenchymal stem cels were able to survive in the infarcted myocardial tissues, and the expression of cardiac troponin T in the cel transplantation group was significantly higher than that in the model group (P < 0.05). Experimental data show that adipose-derived mesenchymal stem cel transplantation can protect the myocardial tissues after myocardial infarction, and effectively improve the myocardial function.

Objective To compare the contrast-enhanced ultrasonography (CEUS) manifestations of pNENs with the pathological changes and to explore the clinical value of CEUS in diagnosis of pNENs. Methods The CEUS of sixteen pathologically diagnosed pNENsfrom April,2012 to February,2014 were retrospectively observed.The CEUS of thirty pathologically diagnosed pancreatic carcinomas during the same period were taken as the control group.The enhancement extent and enhancement patterns of CEUS in pancreatic tumors were analyzed. The specimens of pNENs were stained with HE and CD34 immunochemistry.The grading of interstitial content and Ki-67 index were obtained on HE-stained slices and microvascular density(MVD) were obtained on CD34 immunochemistry stained slices.Spearman rank test analysis was employed to analyze the correlation.Results Among the 16 cases of pNENs,12 cases (75.0%) demonstrated hyper-or iso-enhancement,which included 6 cases (37.5%) showing homogeneous enhancement and 6 cases (37.5%) showing inhomogeneousen hancement,and the other 4 cases demonstrated hypo-enhancement. Among 30 cases of pancreatic carcinomas,25 cases (83.3%) demonstrated hypo-enhancement and 5 cases (16.7%) hyper- or iso-enhancement,and 21 cases (70.0%) demonstrated homogenous enhancement,and 9 cases(30.0%)inhomogeneous enhancement.Taking hyper-or iso-enhancement on CEUS as the diagnostic criteria,its diagnostic sensitivity,specificity,positive predictive value,negative predictive value,and accuracy were 75.0%,83.3%,70.6%,86.2%,80.4%respectively.Negative and positive correlation of the enhancement extent of pNENs with the interstitial content(r =-0.880,P < 0.001) and MVD (r =0.658,P =0.003) were observed,respectively.Six tumors with inhomogeneous enhancement contained cystic degradation or necrosis under microscope. Conclusions CEUS is an effective and non-invasive diagnostic approach for pNENs and can reflect the pathological changes.Hyper-or iso-enhancement of CEUS is typical appearance of pNENs.

Objective To explore the effective treatment of acute deep venous thrombosis(DVT) of left lower extremity accompanied with Cockett syndrome.Methods The data of 16 patients with acute DVT of left lower extremity accompanied with Cockett syndrome,who were admitted to our hospital from August,2004 to January,2008,were analyzed retrospectively.Inferior vena caval filters were inserted and thrombectomy was done to all of the 16 patients;PTA and stent insertion were done in 13 patients and PTA only in the other 3 patients.Anticoagulation,thrombolysis and antiplatelet therapy were given postoperatively to all the patients.Results There was no death or pulmonary embolism in all 16 patients;Forteen patieats had good outcome,2 had acute DVT of left lower extremity one day after surgery,and limbs swelling subsided after anticoagulation,thrombolysis and antiplatelet treatment before their discharge.Forteen patients were followed up from 1 month to 25 months(average 11 months),and 2 patients had post-DVT syndrome,but the others had no swelling or varicose veins of the lower extremity.Conclusions Most patients with acute DVT of left lower extremity accompanied with Cockett syndrome could get satisfactory outcome with thrombectomy,PTA and stent insertion.

Objective To study the apoptosis of ovarian carcinoma cell strain COC1 induced by arsenic trioxide (As_2O_3). Methods The effect of arsenic trioxide on the proliferation of ovarian carcinoma cell strains were examined, using Methyl thiazolyl tetrazolium(MTT) assay. Flow cytometry(FCM) was used to detect apoptosis percentage and phase distribution of cell cycles. After being exposed to As_2O_3 solution of different concentration, apoptosis morphologic features of COC1 were observed by TdT-mediated dUTP nick end labeling (TUNEL). Results Inhibition of As_2O_3 on the growth of COC1 was increasing with passing of time and increasing of concentration. After 48h of exposure to 1.5 ?mol/L As_2O_3, COC1 cell strains presented apoptosis morphologic change, and the number of apoptosis cells increased with the passage of time. After treatment with 3.0 ?mol/L or 1.5 ?mol/L As_2O_3, the percentage of COC1 cells in G_2/M phase declined, and the percentage of cells in G_1 phase increased with the passage of time. These results suggested that As_2O_3 inhibited the cellular proliferation of COC1 cells via arrest of cell cycle. Conclusion Arsenic trioxide can induce apoptosis of ovarian carcinoma cell strain COC1. It can block the cell cycle at the G_1 phase, which is one of the possible mechanisms of apoptosis induced by As_2O_3.

This paper, using acetylcholinesterase (AChE) histochemistry, brain-lesion and di-isopropylfluorophosphate (DFP) pretreatment techniques, studies AChE distribution in the tectum-nucleus isthmi systems in frogs and pigeons. In these two species of animals, the tectal laminae densely stained for AChE are roughly coincided with the retinotectal projections. Staining pattern in the frog nucleus isthmi consists of 3 areas with different staining intensities. The dorsolateral area being most densely stained. In pigeons, the nucleus isthmi pars parvocellularis (Ipc) and pars magnocellularis (Imc) are densely and evenly stained. Following local lesion of tectum, stainings in the frog nucleus isthmi and pigeon Ipc are topographically reduced or disappeared. DFP-treatment shows that tectal cells, with the exception of cells in layer III containing rich AChE, have moderate or low concentrations of AChE. The isthmic cells are rich in AChE. In the tectum-lesioned pigeons, AChE-stained isthmic cells in the topographical area are reduced in number and paler in color. These results suggest that in amphibians and birds both the tectoisthmic projection and the isthmotectal projection could be cholinergic pathways in nature.

Objective To study the changes of gastrin 17 (G17) and pepsinogen (PG) after gastric bypass surgery in gastric antrum resection, and the influences of different surgical methods on postoperative peptic ulcer. Methods Clinical data of 63 patients with gastric bypass surgery in our hospital from October 2013 to October 2015 were divided into resection of pyloric antrum group (n=33) and preserved pyloric antrum group (n=30). The values of G17, PGⅠ, PGⅡand PGⅠ/PGⅡwere detected by enzyme linked immunosorbent assay at 1 month, 6 months and 12 months after operation. The correlation between the different surgical methods and the incidence of peptic ulcer was analyzed between two groups. Results The G17 levels were significantly decreased in resection of pyloric antrum group 6 and 12 months after operation than those in preserved pyloric antrum group (P<0.05). Compared with preserved pyloric antrum group,PGⅠ and PGⅡ levels was significantly decreased 12 months after operation (P<0.05). There was no significant difference in the ratio PGⅠ/PGⅡat 1 month, 6 months and 12 months after operation between two groups (P>0.05). There was no significant difference in postoperative peptic ulcer between two groups (P>0.05). Conclusion Gastric bypass after resection of the pyloric antrum can reduce the postoperative secretion of G17, PGⅠ and PGⅡ, but which can not reduce the incidence of postoperative anastomotic ulcer.
