Objective To explore the effects of anatomical and nonanatomical hepatectomy on the prognosis of patients with hepatocellular carcinoma(HCC).Methods A total of 62 HCC patients were enrolled,including 33 cases of anatomical hepatectomy(Group AH)and 29 cases of nonanatomical hepa-tectomy(Group IH).The operation situation and hematocrystallin(HB)loss were record.Fasting venous blood of HCC patients were extracted for detection of circulating AFP mRNA expression.The recurrence, mortality and complication rate were recorded at the same time.Results The operative time of Group AH was significantly higher than that of Group IH,while the bleeding volume and HB loss were lower(P<0.05).There were no significant differences in AFP mRNA expression and recurrence rate.The short-term mortality rate of Group AH was lower than Group IH(P<0.05 ),but their long-term mortality rates were similar(P>0.05 ).There was no significant difference in complication rate between groups.Patients of Group AH got more hepatosis due to liver cirrhosis or fibrosis,while patients of Group IH got more bleeding or infection due to the central tumor.Conclusion Anatomical hepatectomy has advantages in protecting artery and improving prognosis for HCC patients,but it has surgical risks for patients with serious patholog-ical damage in hepatic lobes,and nonanatomical hepatectomy may be considered.

MicroRNA ( miRNA) is a family of 19 - 24 nucleotides small non - coding RNA in eukaryotic organisms , which can regulate genes at the post - transcriptional level. miRNA has been shown to be involved in a variety of cellular processes such as development, proliferation, differentiation, apoptosis etc, and is closely related to the oncogene-sis. Recent study indicates that several miRNAs play an important role in initiation and progression of hematological malignancies. miRNA expression profiling has identified signatures associated with diagnoses, prognoses and therapy of hematological malignancies. The review discusses miRNA and its biogenesis, functional mechanisms and potential role in the diagnosis , prognoses and therapy of hematological malignancies.

With the development of molecular mechanisms of hepatocelluar carcinoma,targeted therapy has been a research hotspot in recent years.Some target agents of hepatocellular carcinoma have been approved.We summarize the progress of targeted therapy for hepatocellular carcinoma in this paper.

With the wide application of liver transplantation techniques,rapid development of digital imaging medicine and continuous update of surgical implements,the theory of precision hepatectomy still keeps optimizing.Precision hepatectomy is not a surgical implement or surgical technique,but a concept of liver surgery emphasizing less bleeding,minimal invasion,fast recovery and long-term curative effect,which is updating and improving with the development of modern science.Much less intraoperative bleeding,shorter operation time,better postoperative recovery and long-term survival should be the chief pursuit and principle of precision hepatectomy.

Objective To summarize the nursing care and cooperation with surgeons using transoral Orvil EEA stapler during total laparoscopic gastrectomy (TLG).Methods We present our initial experience of nursing care and cooperation with surgeons for 8 patients undergoing TLG using a circular end-toside anastomosis created with the transoral directed EEA circular stapler Orvil.Results The surgeries of all 8 patients were successfully completed under our good cooperation with surgeons using the technique of Orvil system.Conclusions Good preparations and knowing well the surgical procedures were the key points to achieve success using the transoral Orvil EEA stapler for patients undergoing TLG.

Hepatic satellite cell (HSC) is a kind of nonparenchymal cells in the liver,which releases various collagenous fibers and cytoskeletal proteins,playing an important role in the pathophysiological changes of the liver.In normal,HSCs maintain normal tissue architecture via regulating the synthesis and degradation of extracellular matrix (ECM) proteins.During liver injury,HSCs were activated.Activated HSCs are the main cells that lead to the accumulation of extracellular matrix,which is the main reason of hepatic fibrosis,cirrhosis and liver failure.Therefore,lucubrating the role and mechanism of HSC in the progress of hepatic disease and investiating the HSC-related therapeutic strategies have practical significances for the prevention and treatment of liver injury and raise of patients' survival rates in clinical practice.

With the improvement of endoscopic retrograde eholangiopancreatography (ERCP) technology, endoscopy is not only applied to diagnosis, but also utilized to therapy for cholangiopancreatic neoplasm. This article is to summarize the application of endoscopic technology on cholangiopancreatic neoplasm.

Objective:To evaluate the expression of EGFR and gene nm23H1 and their relation to the tumor oncogenesis and progress of cholangiocarcinoma.Methods:SABC immunohistochemistry was used to detect the expression of EGFR and nm23H1 in cholangiocarcinoma and cholangitis tissue.Results:The positive rate of nm23H1 in cholangiocarcinoma was lower than cholangitis(P

OBJECTIVE:To investigate the effects of early before PCI and immediate application of tirofiban on coronary blood flow and myocardial perfusion in patients with high risk acute coronary syndrome (ACS). METHODS:100 high risk ACS patients were randomly divided into observation group and control group,with 50 cases in each group. Two groups were given tiro-fiban;observation group was given medicine 10 μg/kg within 3 min,4-6 h before PCI,with the velocity of 0.15 μg/(kg·min)till 24 h after PCI. Control group was given medicine at the beginning of PCI,route of administration was same as observation group. The incidence of TIMI blood flow grading,TIMI myocardial perfusion grade (TMPG),cTn Ⅰ,PAR and main adverse cardiac events(MACE)were compared between 2 groups before and after treatment. RESULTS:After operation,the patients of 2-3 grade TIMI blood flow and 2-3 grade TMPG in 2 groups were significantly more than before;the patients of 2-3 grade TMPG in observa-tion group was significantly more than in control group,with statistical significance(P<0.05). After treatment,cTn Ⅰof 2 groups were significantly increased,while PAR were significantly decreased,with statistical significance compared to before operation (P<0.05);but there was no difference between 2 groups (P>0.05). There was no statistical significance in the incidence of MACE between observation group(8.0%)and control group(16.0%)(P>0.05). CONCLUSIONS:Early application of tirofiban before PCI can effectively improve coronary blood flow and myocardial blood supply in high risk ACS patients.

Objective Antiphospholipid antibody and factor Ⅻ deficiency are among the coagulation disorders that have been implicated in many thrombembolic events. The aim of this study was to investigate the prevalence of antiphospholipid antibodies and factor Ⅻ deficiency in patients with retinal vein occlusion (RVO). Methods The investigation was a case control study. The periphery blood was collected from a cohort of 33 consecutive patients with RVO and 30 age- and gender-matched normal subjects. Anticardiolipin antibody (ACA) was detected by ELISA as binding index (BI) =A value/standard A value. The lupus anticoagulant antibody was examined by APTT test and the activity of factor Ⅻ was detected. This study was approved by The Human Research Ethics Committee of this hospital, and written informed consent was obtained from all the subjects before initiation of any study protocol. Results The total positive rate of APA in RVO group was 24. 24% (8/33), showing a insignificant difference in comparison with control group (6. 67%, 2/30) (P = 0. 085). The positive rate of anticardiolipin antibody in RVO group was 18.18% (6/33), presenting an obvious enhance in control group (P = 0. 025) . Three patients in RVO group disclosed positive response for IgG-anticardiolipin antibody, one patient for IgM-anticardiolipin antibody, two patients for both isotypes IgG and IgM anticardiolipin antibodies, and two patients revealed positive reaction for lupus anticoagulant antibody. The presence of lupus anticoagulant antibody among the patients with ≤ 50 years and ＞ 50 years was similar to that in age-matched controls (P =0. 160, P =0. 206). Factor Ⅻ deficiency was found in 14 of 33 patients(42. 42%) and in 4 of 30 controls(13. 33%) (P = 0. 013). The prevalence of factor Ⅻ deficiency among the patients with ≤50 years and ＞ 50 years was similar to that in age-matched controls (P = 0. 206, P = 0. 052) . Conclusion Our results indicate that the prevalence of ACA and factor Ⅻ deficiency in RVO patients appears to be correlated.
