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.

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.

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.

Ontogenesis of gastrin cells (G cells) and somatostatin cells (D cells) in the gastrointestinal tract was studied by PAP and indirect immunofluorescence method in sixty human fetuses aged 8-38 weeks of gestation. The appearance of D cells and G cells was observed as early as 8-9 weeks of gestation. These cells were not seen in the submucosa and the tunica muscularis except the epithelium of gut. After 12 weeks of gestation, D cells can be found in the mucosa of the whole gut, whereas G cells only in the mucosa of the antrum and small intestine. The distribution, number and the ratio of G cells to D cells were also examined. In addition, we have observed that G cells in the antral mucosa often possessed processes which were considered to have paracrine function. The G cells and D cells were open-type endocrine cells in the human fetal gut except the D cells in the fundic mucosa. The possible function of G cells and D cells in the development of gut was discussed. The ratio of the two cell types in adult human antrum and upper duodenum has also been compared with that of fetus.

Objective To analyse the imaging characteristics of pulmonary tuberculosis(TB) in elder in order to improve its diagnostic accuracy.Methods Radiological and CT fndings of pulmonary tuberculosis in 200 old patients were analysed retrospectively.Results The types of TB in 200 patients were:type Ⅱin 13 cases(6.5%),type Ⅲ in 163 cases (81.5%),accompanied with the pleuritis in 44 cases(22%) and type Ⅳ in 24 cases (12%).The mainly imaging findings included:old lesions in 85 cases(42.5%),exudative and/or multiplicative lesions in 81 cases (40.5%),caseous pneumonia in 47 cases(23.5%),cavitive lesions in 127 cases(63.5%),tuberculoma in 12 cases(6%),miliary nodules in 13 cases(6.5%),TB pleuritis in 68 cases(34%) and enlargement of lymph nodes in 57 cases (28.5%).Conclusion TB in elder is of characteristics of atypical location and unstable morphology.

Objective Observe the pupil constrict response to the pilocarpin,identify the difference of the response between the young and the old.Methods Use the infrared digital camera of sonyF717 to record the dynamic variety of the pupil constrict response to the 1%pilocarpine liposome and the pilocarpine liquid in dark environment.Then deliver the data to the computer,measure the data by imagetool software,analysis the data by the Sigamastat software.Results In darkness,the pupil diameter of the young is equally 6.8?0.643mm,the old is equally 4.4?0.447mm.T test t=16.1,P

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.

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.
