Hepatic hemangioma is the most common benign liver tumors in the clinic.Most of hemangioma does not require aggressive treatment,and the indications for resection remain controversial.Different scholars may have different ideas about the surgical treatment of hemangioma.This article will focus on reviewing literatures about indications of hepatic hemangioma.In this paper,we proposed a new standard of surgical indications that named health-related quality of life.

There are many kinds of diseases in hepatic surgery department including hepatitis,hepatic cirrhosis, liver cancer etl. Most of them are very ditficult to diagnose and treat, so it's necessary to change our traditional clinical practice teaching mode.Role-playing mode increases the interaction between students and teachers, which can achieve the desired effect with entertainment. So role-playing is a new model of clinical teaching as a meaningful innovation.

Hepatic resection has been the main form of the treatment of liver benign and malignant tumors. With the popularity of applications of minimally invasive techniques in surgery in recent years, laparoscopic hepatectomy(LH) application has also achieved a rapid development. It' s advantages are known as a small open incision, light systemic response and rapid recovery, meanwhile it can also attain the same efficiency as the open surgery does. However, there also exist disadvantages, such as complicated conduct, expensive instruments, and bleeding problems. This article reviews the process of development of laparoscopic liver resection, and elaborates its current status, existing problems, and evaluation of its treatment and efficiency.

Objective To investigate the expression of ?-methylacyl CoA racemase (AMACR,P504S) and p63 in prostate carcinoma tissues and the clinicopathologic significance in the diagnosis of the disease. Methods The expression of AMACR and p63 in 39 cases of prostate carcinoma and 24 cases of benign prostate lesions were examined using immunohistochemical method. The association of the AMACR and p63 expression in prostate carcinoma tissues with the differentiation and clinical staging was evaluated. Results The positive rates of AMACR and p63 were 85%(33/39) and 10%(4/39),respectively,in prostate carcinoma tissues; and those were 21%(5/24) and 88%(21/24),respectively,in benign prostatic hyperplasia. There were significant differences of these values between prostate carcinoma and benign prostatic hyperplasia (P0.05). Conclusions Over-expression of AMACR and under-expression of p63 may be the preliminary incident of the formation of prostate carcinoma,which may induce carcinoma into occurrence and progression.Thus it may be an early diagnostic parameter and a novel target for prostate carcinoma treatment.

Objective To construct human-mouse hybrid Fab phage antibody libraries and to select target Fab genes. Methods With Fd repertoire genes of PBMC from hepatoma patients and the chemeric light chain gene of cFab-HAb18, two hybrid Fab phage antibody libraries(pComb3 and pComb3X) were constructed. The GST fusion and non-fusion HAb18GE were used as antigens to select the target antibodies with the optimized strategies of amplifying and screening. Results When pComb3 displaying library was cultivated at 37℃, the target fragments could not be cut out with the restriction endonucleases from most clones of the library, which was an indication of “recombinant-deletion”. But no “recombinant-deletion” was found in pComb3X displaying library. Because of the serious cross-reaction, the phage-display Fab ELISA could not be used for the selection of positive clones. But positive clones could be identified in the supernatant of lysate with ELISA afterbeing induced by IPTG. Conclusion Through the construction of HuMFab phage antibody libraries and the optimization of screening strategies, we get the desired HuMFab genes for subsequent research.

Tumor metastasis and recurrence had become a key to curative effect and long-term survival,and it's hotspot of current clinical oncology research.Differential expression of proteomics between cancer and normal tissue can be used for discovering new tumor markers.Clinical detection of liver cancer-related protein molecules was useful to monitor and assess early diagnosis,recurrence and prognosis of hepatocellular carcinoma.Herein,this article reviewed the research progression of protein molecules in hepatocellular carcinoma.

Asialogycoprotein receptor (ASGPR) is a specific receptor of mammalian hepatocytes,exclusively up-take the glycoprotein in the blood.The number of ASGPR correlates significantly with liver function,and the reduction of the number of ASGPR suggest liver dysfunction.Decreased ASGPR in patients with liver cirrhosis or portal hypertension or hepatocellar carcinoma,lead to varying degrees of liver dysfunction,which made it more susceptible to post operative complications.liver ASGPR scintigraphy with Technetium-99 m DTPA-galactosyl human serum albumin (99m Tc-GSA),combinating with single photon emission computed tomography (SPECT) technology can assess the functional reserve of remnant liver and predict incidence of postoperative complications,then assist to evaluate the use fulness for clinically surgical decisions.Current situation and progress of 99mTc-GSA SPECT imaging in hepatic surgery were reviewed in the paper.

AIM To investigate the inhibitory effect of extract of fu ng i of huaier (EFH) on neovascularization formed by human umbilical vein endotheli al cells (HUVECs) in vitro. METHODS Using MTT assay, flow cytomet ry and Matrigel assay, the effect of EFH on the proliferation and differentiatio n of HUVECs stimulated by vascular endothelial growth factor (VEGF) were evaluat ed in vitro. RESULTS EFH inhibited proliferation of HUVECs stimul ated by VEGF at the concentration of 0 1 to 10 g?L -1 . The antiproliferat itive effect occurred in a dose-dependent manner. Flow cytometry analyses revea led that EFH treatment delayed S-phase progression. A remarkable inhibition of tube formation was observed in the presence of 1 g?L -1 EFH and complete i nhibition was obtained at 10 g? L -1 EFH. CONCLUSION EFH is able to inhibit neovascularization formed by HUVECs. Its mechanism might be rela ted to S-phase progression.

Objective: To explore correlation between plasma oxidized low density lipoprotein (ox-LDL) and endothelial injury degree in patients with coronary heart disease (CHD).Methods: A total of 80 CHD patients were enrolled as CHD group, and 21 healthy subjects were selected as healthy control group.Plasma ox-LDL, circulatory endothelial cell count (CEC), nitric oxide (NO) levels were measured and compared between two groups, and their correlation was analyzed.Results: Compared with healthy control group, there were significant rise in plasma ox-LDL level[(350±173) μg/L vs.(687±169) μg/L]and CEC[(2.5±0.5) ×106个/L vs.(9.0±1.7) ×106个/L], and significant reduction in NO level[(77.4±21.1) μmol/L vs.(52.3±16.6) μmol/L]in CHD group, P<0.05 or <0.01.Spearman correlation analysis indicated that ox-LDL was significant positively correlated with CEC (r=0.793, P=0.019), and ox-LDL, CEC were significant negatively correlated with NO level (r=-0.782,-0.952, P=0.013, 0.021).Conclusion:There are significant positively correlation between ox-LDL and circulatory endothelial cell count(Vascular endothelial injury degree) in CHD patients, therefore, its treatment should focus on anti-inflammatory and endothelial cell function protection.

Objective: To select anti-HAb18G (hepatoma associated antigen) human Fd fragments with guided selection of L chain of chimeric Fab-HAb18. Methods: The human Fd repertories genes were amplified by RT-PCR from PBMC of hepatoma patients, and cloned into the vector pComb3X with chimeric L chain to construct the human-mouse hybrid Fab phage library. HAblSGE, extracellular region of HAblSG, was used as antigen to screen. The positive clones was obtained by ELISA and FCM with p Ⅲ-fusion Fab antibody. The DNA sequences were analyzed. Results: A human-mouse Fab antibody library were constructed with 2?107 PFU. After 6 rounds panning, 7 positive clones were obtained with ELISA and FCM. And sequences of 2 clones with better affinity were same. The CHI belonged to the IgG2 class as the parent Fd, and the variable region belonged to VH3 family. Conclusions: Through the construction of the HuMFab phage antibody library and chemeric L chain-guided selection, we get the available human Fd fragments for subsequent research.
