Along with the frequent international communication of TCM, translation of related classics becomes increasingly important. The translation of TCM classics' titles, which reveal the content of the classics, is equally essential. Dictated by the translating principles of standardization, correspondence, readability and nationalism, the paper analyzed the translation of TCM classics' titles containing modesty words, and put forward the following translation strategies translation: The method of foreignization is preferred for the translation of titles involving heterogeneous culture in order to retain the unique TCM concept while the method of domestication is advised for the translation of titles involving elements in conflict with the target culture; In the translation of TCM classics' titles containing modesty word(s), weakening or omitting the sense of self-depreciation is proposed. The paper aimed to contribute to the standardization of TCM nomenclature translation in order to promote international dissemination of TCM classics.

Objective To construct 1.3-fold-overlength infectious clone of hepatitis B virus isolated from Chinese patients , observe the expression of plasmid in Huh7 of liver cancer cells and establish genome of HBV in vitro. Methods HBV DNA in serum was extracted from HBV patient. SOE-PCR was performed to produce a 1.3-fold-overlength genome of HBV. The plasmid was named pHBV1.3 (C). After that,pHBV1.3 (C) was transfected into Huh7 cells, HBV related viral antigens and DNA were detected by ELISA,Western Blot and Fluorescence quantitative PCR. Furthermore, adefovir dipivoxil, a clinic anti-viral drug, was utilized to test the sensitivity of the new infectious clone. Results An infectious clone of pHBV1.3 (C) was successfully constructed. HBV gene carried in pHBV1.3 (C) could be efficiently replicated and expressed in Huh7 cells. Adefovir could inhibit HBV replication in this HBV cell model. Conclusions A recombinant plasmid containing 1.3-fold-overlength of HBV genotype C was successfully constructed. This construct is competent to support viral transcription and replication in vitro , suggesting that infectious cells are expected to be a new model of HBV infection in vitro.

Objective To investigate the risk factors of acute kidney injury following coronary artery bypass graft(CABG).Methods Twenty-six patients suffering from acute kidney injury following CABG as the patient group and 59 individuals without impairment of renal function as the control from January 2008 to September 2012 in the First People's Hospital of Yichang according to a retrospective case-control study and nonconditional multivariable Logistic regression analysis method..Results Among the 85 patients undergoing CABG,26 suffered acute kidney injury following CABG with a morbidity rate of 30.59％.Identified risk factors for acute kidney injury following CABG included pre-operative mederale-sever cardiac insufficiency,prolonged mechanical ventilation,prolonged stay in ICU and anemia before surgery.The identified independent risk factor of acute kidney injury following CABG was pre-operative mederale-sever cardiac insufficiency (OR =3.206,95％ CI:1.067-9.631).Condusion Pre-operative mederale-sever cardiac insufficiency was an independent risk factor of acute kidney injury following CABG.

Objective To assess the diagnostic value of magnetic source imaging(MSI) in the preoperative localization of focal cortical dysplasia(FCD). Methods Eighty-two patients with intractable epilepsy resulting from FCD undergone preoperative assessment including MSI, video electroencephalography(VEEG) and electrocorticography(ECoG)from February 2006 to June 2012.The consistency between pre- and intra-surgical assessment was evaluated. For patients who had consistent results,postoperative curative effect was also recorded. The accuracy and predictive values of noninvasive preoperative tests were compared by χ2 test. Results For MSI and ECoG, their results were consistent in 57 cases, partially consistent in 14 cases, and inconsistent in 11 cases. In the postoperative follow-up of 57 patients with consistent results, there were 46 cases with Engel class Ⅰ, 3 cases with Engel class Ⅱ, 4 cases with Engel class Ⅲ, and 4 cases with Engel class IV. For VEEG and ECoG, the results were consistent in 43 cases, partially consistent in 33 cases, inconsistent in 6 cases.The postoperative follow-up showed that 27 cases were graded as Engel classⅠ, 5 cases as Engel classⅡ,7 cases as Engel classⅢ, and 4 cases as Engel class IV. There were statistically significant differences(χ2=5.023,P=0.025)of the concordance rate with ECoG between MSI(69.51%,57/82)and VEEG(52.44%,43/82). In the postoperative follow-up of patients with consistent results, the curative effect was better in group MSI than in group VEEG (χ2=3.989,P=0.046). Conclusions Preoperativelocalization by MSI shows advantage over VEEG, which meanswhen it achieves an agreement with ECoG, patients with FCD may get better prognosis from the surgical process.

AIM: To investigate the efficacy of dendritic cells (DCs) that augments the cytotoxic activity of cytokine-induced killer (CIK) cells, natural killer (NK) cells from a same donor and the CD45RO expression on CIK cells. METHODS: The expanded killer cells were divided into two groups: group A was pre-cocultured with DCs for 6 days, group B was the control that without any stimulation. Cytotoxicity of CIK and NK cells was measured at different effect-target ratio against K562 and HL-60. CD45RO and CD45RA expression on CIK cells in different groups were detected by flow cytometry. RESULTS: Cytotoxicity of CB derived killer cells was positive correlation with effect-target ratio. The cytotoxicity of group A against HL-60 was higher than that of group B significantly. At 20∶1 effector-target ratio, the lytic activity of group A CIK, NK cells against K562 was higher than that of group B significantly, but no significant difference between them at 10∶1 effector-target ratio. The CD45RO expression on CIK cells in groups A was significantly higher than that in groups B. CONCLUSION: CIK and NK cells cocultured with DCs can augment the killer's cytotoxicity against tumor cells and promote the CD45RO expression on CIK cells.

AIM: To study the isolation,expansion and purification of mesenchymal stem cells(MSCs) from human umbilical cord blood(UCB),and investigate some biological identities of MSCs.METHODS:(1) MSCs of UCB,adult bone marrow(BM) and fetus BM were isolated by centrifugation with Ficoll,and the different kinds of MSCs were observed everyday.(2) Surface markers of MSCs were identified by flow cytometry.(3) The level of HGFs(TPO,SCF,FLT-3L,IL-6) secreted by different sources of MSCs was checked by ELISA method.RESULTS:(1) No difference in morphology of the colonies between UCB MSCs and BM MSCs was observed.However,the mononuclear cells needed in culture of UCB MSCs was about 3 times more than that in culture of BM MSCs.The times of UCB MSCs colony formation and confluencing were longer than that of BM in primary culture.(2) After passaged,there was no significant difference in the proliferation rates of 3 kinds of MSCs.Only 4 of 15 UCB samples contained a homogeneous population of MSCs.(3) UCB MSCs shared the same markers with BM MSCs.Neither hematopoietic marker nor immunologic recognition antigens were expressed.(4) The level of hematopoietic growth factors(HGFs) secreted by 3 kinds of MSCs was similar.CONCLUSIONS:(1) MSCs were isolated from UCB,but the amount of MSCs in UCB was smaller than that in BM,and just seldom samples of UCB contained homogeneous MSCs.(2) MSCs from UCB and BM shared the same biological characteristics,such as proliferation ability,surface markers,immunophenotypes and HGFs secretion.

Objective To observe the effect of exposure of emphysema with intermittent hypoxia on oxidative stress injury of myocardial cells in rats. Methods Sixty male Wistar rats were divided randomly into four experimental groups(each n=15). The normal control group was bred normally. The emphysema group was exposed to cigarette smoke twice a day(once 30 minutes). The intermittent hypoxia(IH)group was exposed to intermittent hypoxia circumstance 8 hours/day,and the emphysema with IH group was exposed to cigarette smoke twice a day (once 30 minutes)and intermittent hypoxia circumstance 8 hours/day. Each group was exposed for 8 weeks. At the beginning of 9 weeks,the blood gas analysis was performed in 5 rats selected randomly from each group,and the rest rats were sacrificed and their hearts and lungs were taken. Under light microscope,the lung tissues stained with hematoxylin-eosin(HE)were examined. The lung pathology and the results of blood gas analysis showed that the emphysema with IH rat model was established successfully. The levels of malonaldehyde(MDA)and superoxide dismutase(SOD)in rat myocardium were measured by enzyme-linked immunosorbent assay(ELISA),and the subunit p22phox mRNA expressions of nicotinamide adenine dinucleotide phosphate(NADPH)-oxidase were detected by real-time reverse transcription-polymerase chain reaction(RT-PCR). Results Compared with the normal group, the MDA levels and p22phox mRNA expressions were increased obviously in emphysema group, IH group and emphysema with IH group〔MDA(μmol/g):2.93±0.54, 3.58±0.63, 4.51±0.72 vs. 1.75±0.56, p22phox mRNA:0.043±0.004,0.067±0.015,0.123±0.016 vs. 0.018±0.002,all P<0.05〕,but the activities of SOD were decreased significantly(U/mg:36.07±4.79,33.51±7.12,24.29±5.36 vs. 46.08±5.12,all P<0.05). In emphysema with IH group,the increase of MDA levels and p22phox mRNA expressions and decrease of SOD levels were more remarkable compared with those in emphysema group and IH group(all P<0.05). The expression of p22phox mRNA was positively correlated with MDA level(r=0.734,P<0.001). Conclusion The myocardial tissue oxidative stress injury in rats induced by emphysema with intermittent hypoxia exposure is more serious than that induced by exposure of either emphysema or intermittent hypoxia alone,NADPH oxidase possibly being the important medium of myocardial cell response to oxidative stress.
