Objective To obtain the sequence of recombinant human basic fibroblast growth factor (rhbFGF) with endonuclease sites of BamHI and Pst Ⅰ by PCR based gene assembly and construct the recombining vector of rhbFGF gene by TA cloning technique.Methods The rhbFGF gene sequence which was designed for lactococcus with endonuclease sites of BamHI and Pst Ⅰ was divided into 22 oligonucleotides by DNASTAR 6.0 (bFGFl-bFGF22).The 22 oligonucleotides were spliced by PCR based gene assembly to get the rhbFGF eDNA with endonuclease sites of BamHI and Pst Ⅰ.The PCR product was inserted into the PMD18-T VECTOR.The recombining vector were converted to the competent E.coli TOP10.The clones generated from LAB were analyzed by miniprep isolation from LAB host.They were identified by the restriction enzyme cuuing and sequencing.Results The rhbFGFcDNA synthesized by PCR based gene assembly with endonuclease sites of BamHI and Pst Ⅰ was verified by 2％ agarose electrophoresis.The recombining vector of rhbFGF gene by TA cloning technique was identified by enzyme digestion and gene sequencing.Conclusions The TA cloning vector of recombining hbFGF with endonuclease sites of BamHI and Pst Ⅰ was constructed successfully.

Objective To explore the feasibility of labeling in vitro rabbit osteoblasts with Qtracker and the features of Qtracker-labeled rabbit osteoblasts. Methods A healthy male rabbit, 3 months old, weighing 2 kg, was used in this study. After bone marrow was aspirated, bone marrow stromal cells (BMSCs) were isolated and cultured using the adherence method in vitro. The third passage of BMSCs was induced into osteablasts before incubation with Qtracker at concentrations of 1, 2, 4, 8, 16, 32 nmol/10~6 cells (Groups A, B, C, D, E, F respectively). Cells not labeled by Qtracker served as negative control (Group G). The following parameters were measured: induction, differentiation and determination of rabbit osteoblasts; the optimal mass concentration of Qtracker labeling by fluorescence microscopy and flow cytometry; the cell sur-vival rates at various concentrations of Qtraeker labeling by trypan-blue exclusion; Qtracker-labeled cell pro-liferation by MTr. Results The primary and the passage rabbit BMSCs were chiefly of fusiform shape. Rabbit BMSCs differentiated into osteoblasts following induction. The osteoblasts cytoplasm showed green fluorescence under fluorescence microscopy after being labeled by Qtracker. The mean labeling rate increased with the increased concentration of Qtracker, reaching up to (93.58±2.08) % after incubation at 8 nmol/ 10~6 cells by fluorescence microscopy, and (95.24±1.31) % by flow cytometry. There were no significant differences between Groups D, E, F(P>0.05), but significant differences were found between Groups A, B, C and Groups D, E, F (P<0.05). The labeling rate for Group G was 0. The cell survival rates were all above 96% (P>0.05) . No significant differences were found in the cell proliferation among various con-centrations (P>0.05). Conclusions Qtraeker can be used as a labeling marker for rabbit osteoblasts. When the concentration is at 8 nmol/10~6 cells, optimal labeling effect can be achieved. Rabbit osteoblasts labeled with Qtracker are of high efficiency and safety.

Objective To evaluate the therapeutical effect of dopaminergic neurons induced by transplantation on Parkinson's disease (PD) rats. Methods Mesencephalic nerve stem cells (NSCs) were induced by striatal extracts to differentiate into tyroxine hydroxylase (TH) positive dopaminergic neurons. The differentiated cells were transplanted into the striatum of PD rats. The survived cells were detected by TH immunocytochemical staining. The therapeutical effect was observed using apomorphine induced rotation. Results Mesencephalic NSCs could be induced to differentiate into dopaminergic neurons which could survive in the host for long time after cell transplantation, and could improve the apomorphine induced rotation. Conclusion The induced mesencephalic NSCs have the obvious therapeutical effect on PD.

In this article,2017 Fleischner society lung nodules guidelines for management of lung nodules accidentally discovered and lung nodule measurement were briefly introduced.Electronic questionnaires were sent to doctors nationwide,and their familiarity and consistency with these recommendations were assessed.The results showed relatively high familiarity with the guideline,but the consistency in clinical practice was still unsatisfactory,suggesting that further promotion of these guidelines is necessary in the future.

Objective To study the radiosensitizing effect of caffic acid phenethyl ester(CAPE)on human cervical cancer HeLa cells.Methods MTT assay was used to measure the relation between the inhibition effect and CAPE concentrations by CAPE with different concentrations on HeLa cells for 24 hours.HeLa cells were divided into the control and experimental groups,both of which were given 0,2,4,6 and 8 Gy of 60Co γ-irradiation,respectively.The cell clones were counted.Meanwhile HeLa cells were divided into the control,CAPE,irradiation and combination groups.Flow cytometric analysis was adopted to detect the changes of cell cycle distribution induced by CAPE.Results The inhibition rate of CAPE acting on Hela cells increased with concentrations(F=126.49～3654.88,P＜0.01).HeLa cells cloning survival decreased with the increase of radiation dose(F=174.42～9422.81,P＜0.01).At the game radiation dose,HeLa cells cloning survival was less in experimental group than conlrol group(F=120.14～251.91,P＜0.01).The mean lethal dose(D0)(1.45 and 1.82 Gy)and the quasi-threshold dose(Dq)(1.89 and 3.21 Gy)of HeLa cells in experimental group decreased comparing with control group,SER was 1.26.Compared with the sole irradiation group,cells in G2/M phase of the CAPE group and the sole irradiation group increased(P＜0.01)while the combination group decreased(P＜0.01).Conclusions CAPE could increase the radiation sensitivity of HeLa cells by G2/M arrest and may be related to the inhibition of the sub-lethal damage repair.

Objective To explore risk factors of influencing operating efficiency of endoscopic submucosal dissection (ESD) for gastric mucosal lesions. Methods The data of 304 cases with gastric mucosal lesion undergoing ESD in Xijing Hospital of Digestive Disease from April 2009 to February 2017 were retrospectively analyzed. The procedure time and complete resection rate ( R0 resection rate ) were regarded as indicators of ESD efficiency. Risk factors influencing procedure time and R0 resection rate were analyzed using Chi-square test and logistic regression. Results Using median procedure time of 45 min as the cutoff value, Chi-square test showed that specimen size ( P=0. 000) , lesion location ( P=0. 001) , and pathological type ( P=0. 003) affected the operation time. Further logistic regression analysis indicated that specimen size (≥40 mm/<40 mm, P<0. 001, OR=3. 748, 95％CI: 2. 247-6. 254) and lesion location (upper or middle 1/3 of stomach/lower 1/3 of stomach, P=0. 001, OR=2. 180, 95％CI: 1. 318-3. 606) were independent risk factors of procedure time. Using R0 resection as outcome measure, neither single nor multiple parameter analysis was statistically significant. Conclusion Specimen size and lesion location are independent risk factors influencing efficiency of gastric mucosal ESD, and could be possibly used to estimate the procedure time of ESD.

Objective To evaluate the relationship between different levels of central venous pres-sure (CVP) and blood loss during pediatric living donor liver transplantation (LDLT). Methods Pediat-ric patients underwent LDLT in Renji Hospital from 2006 to August 10, 2016 were retrospectively reviewed. The patients were divided into 2 groups according to the different CVP levels before peritoneum closure:central venous pressure<10 mmHg group ( group L) and CVP≥10 mmHg group ( group H) . The primary outcome measure was intraoperative blood loss. The secondary outcome measures were duration of mechani-cal ventilation in intensive care unit (ICU), duration of ICU stay, length of postoperative hospital stay, intraoperative blood loss, intraoperative blood transfusion, intraoperative volume of liquid infused, opera-tion time and anesthesia time. Results A total of 442 pediatric patients were enrolled in this study, with 209 cases in group L and 233 cases in group H. Compared with group H, the intraoperative blood loss was significantly decreased, the anesthesia time, operation time and length of postoperative hospital stay were shortened ( P<0. 05) , and no significant change was found in intraoperative blood transfusion, intraopera-tive volume of liquid infused, duration of mechanical ventilation in ICU or duration of ICU stay in group L ( P>0. 05) . Conclusion Maintaining intraoperative CVP<10 mmHg can markedly reduce the blood loss during LDLT and is helpful for postoperative recovery in pediatric patients.
