Objective To evaluate the effects of IL-1? and combination of IL-1?,IL-11,LIF and GDNF on inducing human neural stem cells(hNSCs)to differentiate into dopaminergic(DA)neurons in vitro. Methods A great deal of neurospheres was obtained by the technology of serum-free culturing and single-cell cloning,and was splitted into 3 groups,which were cultured in different media.In control group,the differentiation medium used only contained 10%FBS.In IL-1? group,the medium contained IL-1? and 10%FBS.In united factors group,the medium contained IL-1?,10%FBS supplemental with IL-11,LIF and GDNF.After 3 weeks,the tyrosine hydroxylase(TH)positive cells were detected by using immunofluorescence,and image processing about the number,the induced differentiational rate,the cell bodies' areas and the cells' perimeters of TH positive neurons was carried out.TH/MAP-2 double-immunofluorescence labeling was used to calculate the percentage of DA neurons in total neurons. Results In the control group,there were few TH positive neurons with poorly developed morphology.The presence of IL-1? induced more DA neurons,but these cells were still immature.In the united factors group,the number of maturer TH positive DA neurons was the most. Conclusion IL-1? has an obvious effect on inducing hNSCs derived from human fetal mescenphalon to DA neurons.The utilization of IL-1?,IL-11,LIF and GDNF in combination has a cooperative effect on inducing differentiation of hNSCs to mature DA neurons.

Objective To explore the value of the LigaSure vessel sealer in laparoscopic gastroenteric surgery. Methods Laparoscopic gastroenteric operations were performed in 45 cases under general anesthesia by using the LigaSure vessel sealer, involving 14 cases of colon cancer, 19 cases of rectum cancer, 6 cases of gastric cancer, 1 case of small intestine cancer and 5 cases of gastric ulcer. Results Laparoscopic operations were performed successfully in all the cases. The operation time was 120～220 minutes, the blood loss was 50～198 ml, and the number of lymph nodes resected was 5～18. No severe complications occurred. Postoperative pathological examination revealed adenocarcinoma in cases of malignant tumors, with negative margins. Conclusions Use of LigaSure vessel sealer in laparoscopic gastroenteric surgery offers not only an excellent hemostatic effect but a satisfactory function for dividing and dissecting tissues.

Objective To investigate expressions of the vascular endothelial growth factor (VEGF) family and their receptors in cardiac repair/remodeling after myocardial infarction (MI).Methods The infarcted rat heart model were constructed,real time PCR (RT-PCR) and Western blots (WB) were used.Results Compared to the normal myocardium,VEGF-A was significantly decreased in MI group during the 42 days observation period but decreased at day 1,which was 0.89 ±0.04 of control group in D1,0.25 ±0.03 of control in D14; VEGF-B was significantly suppressed in the infarcted heart,which level was 0.09 ± 0.04 of control; However,VEGF-C and VEGF-D were markedly increased in the infarcted heart in MI group,which was 5.31 ± 0.21 and 9.24 ± 0.47 times of control.Meanwhile,VEGFR-1 and 2 were 0.11 ± 0.02 and 0.14 ± 0.04 of control in the infarcted heart,but VEGFR-3 was significantly increased in blood vessels,6.81 ± 0.42 times of control group.Conclusions VEGF isoforms and VEGFR subtypes were differentially expressed in the infarcted heart.It suggests that these isoforms may regulate multiple responses during cardiac repair/remodeling.

Objective To explore protective effect of Anisodamine against injure of cochlea hair cells induced by ionizing radiation. Methods 50 healthy guinea pigs were randomly divided into 3groups: radiation group( n = 20) , anisodamine protective group( n = 20) and control group( n = 10). 20ears were observed in each group. Tempora of guinea pigs in anisodamine protective group and radiation group were exposed to fractional doses of 6 MeV electron beam produced by linear accelerators (2 Gy/d)with a total dose of 60 Gy. Animals were injected intramuscularly with anisodamine (20 mg/kg) in protection group and equal saline solution in irradiated group, respectively, 30 min pre-irradiation.Morphological and functional changes in the guinea pig cochlea were observed. Results After radiation,the average ABR threshold value of the radiation group (52. 27 ± 2.42 dB peSPL) was significantly higher than that of the anisodamine protection group (37.65 ± 1.92 dB peSPL, t = 2.01, P＜ 0.05 ), and outer fair cells of cochlea reduced greatly in quantity by observing the stretched preparations of cochlea basilar membrane ( F=135. 362, P＜ 0.05 ). Under transmission electron microscope, outer fair cells of cochlea in the radiation group had obscure boundaries and swelled to lose their original shapes. Meanwhile, cell implement and the nucleus were obviously obnormal after radiation. In the anisodamine protection group,the boundaries of cochlea outer fair cells were very clear and the cells swelled a little. Cell implement and nuclear envelope were complete. Cochlea outer fair cells in the control group were found to line up in order with no collapse and reduction in number under scanning electron microscope, but those in the radiation group collapsed obviously, reduced in number and aligned in a state of chaos, while the outer fair cells in the anisodamine protection group regularly posed on the whole and the collapse was occasionally found.Conclusions The 60 Gy radiation at fractioned dose on the tempuses of the guinea pigs could cause damage to the cochlea hair cells. Anisodamine might have a protective effect against radiation damage.

Objective To study the anesthetic effect and influence to circulatory and respiratory function of target controlled infusion(TCI)and intravenous injection of propofol anesthesia in elderly patients undergoing colonoscopy.Method 50 patients above 55 years of age undergoing colonoscopy were randomly allocated to 2 groups.The TCI group received target controlled infusion of propofol with a target concentration of 3?g/ml.The injection group received intravenous injection of 2mg/kg propofol with addition of 20-50mg propofol for each time at intervals during anesthesia when necessary.BP,HR,SpO2,and limb motion were detected during colonoscopy operation,and the time of eye-open and word-response after colonoscopy were also recorded.Results No significant difference was found in colonoscopy time and limb motion response between the two groups.Patients in TCI group consumed more propofol and opening of eyes was delayed compared to those patients in the injection group(P

OBJECTIVE:To investigate the significance of tacrolimus blood concentration monitoring to the therapy of mem-branous nephropathy. METHODS:41 patients with membranous nephropathy received tacrolimus,and the blood concentration of ta-crolimus reached to steady state. The trough concentration of tacrolimus was determined by EMIT. The patients were followed up, and clinical therapeutic efficacies were recorded. The relationship of blood concentration of tacrolimus with clinical efficacy was evaluated by SPSS 16.0 software. RESULTS:The blood concentration of tacrolimus was(7.47±2.74)ng/ml in complete remission (CR)group,(5.72±1.19)ng/ml in partial response(PR)group,and(3.30±1.08)ng/ml in no response(NR)group,with total remission rate of 75.61%. The blood concentration of CR group was the highest,followed by PR group and NR group,there was statistical significance among 3 groups(P<0.05). CONCLUSIONS:The clinical efficacy of tacrolimus in the treatment of nephrot-ic syndrome is correlate to the blood concentration intimately. Trough concentration monitoring of tacrolimus has important signifi-cance to the treatment of membranous nephropathy.

Twenty six patients with liver cancer who received liver transplantation were enrolled in the study. The patients were assessed by SF-36 scale and QOL-LC V2.0 scale before and 0 -6, 7 - 12, > 12 months after the liver transplantation. Scores in physical function domain and social function domain decreased significantly in the early stage post LT (0 -6 month post-LT). While in later stage ( >7 months post-LT), the scores showed no significant difference or even higher than that of pre-LT. In psychological function domain, no significant difference was found pre- and post-LT. The scores were improved significantly in later stage post-LT than pre-LT and early stage post-LT.

Objective To study the in vitro culture condition for melanoblasts from human foreskin tissue. Methods The skin tissue taken from foreskin of children was treated with 0.5% dispase Ⅱ to separate epidermis from dermis, then with trypsin to obtain single cell suspension, which was cultured in modified medium for melanoblasts, i.e., MCDB254 medium supplied with several cell growth factors. Finally, melanoblasts were obtained based on the difference of adhesion speed. The morphology and proliferation of cultured melanoblasts were observed under a light microscope. DOPA staining, immunostaining with anti- S-100 and -tyrosinase related protein 2 (TRP2) antibodies, and transmission electron microscopy were per- formed to identify the cultured melanoblasts. Results The cultured human melanocytes displayed a match-like shape, scattered arrangement, syrmnetric double poles, slim cell body, highly refractive nuclei; meanwhile, the melanoblasts exhibited plentiful cytoplasm, large volume, bipolar or irregular shape and clonal growth. Additionally, the melanocytes were positive for TRP2, S-100 and Dopa staining, while the melanoblasts were positive only for TRP2. Electron microscopy revealed the presence of mature melanin granules (stage Ⅲ-Ⅳ ) in melanocytes but immature melanin granules (stage Ⅰ ) in melanoblasts. Conclu- sion Stable pure culture of melanoblasts has been realized with the reformed medium, which may lay a foundation for the investigation into the mechanism of epidermal pigmentation.

Objective:To investigate the relationship between gene polymorphisms of disease-relevant multiple cytokines including TNF-α,IL-6,IL-10,TGF-β1,IFN-γand acute graft versus host disease(aGVHD) in allogeneic hematopoietic stem cell trans-plantation ( allo-HSCT ) . Methods:32 cases of recipients received allo-HSCT and 36 cases of normal groups in January 2014 to December 2015 were selected as objects of study. We detected genotypes on specific SNP of target genes by polymerase chain reation ( PCR) combined with gene sequencing and observed the occurrence of aGVHD in postoperative recipients. The influence of cytokine gene polymorphisms on prognosis of allo-HSCT patients was analyzed,and the potential relationship between specific SNP mutation of the disease-relevant cytokine genes and severity of aGVHD was discussed. Results:Distribution of cytokines gene polymorphism including TNF-α-308(G/A),IL-6-174(G/C),IL-10-1082(A/G),TGF-β1+915(G/C),IFN-γ(T/A) had no significant differences with incidence of severe aGVHD(P>0. 05). However,the occurrence of severe aGVHD in allo-HSCT recipients with C/T genotype was significantly higher than C/C and T/T in SNP of TGF-β1+869(P<0. 01). Conclusion:Gene polymorphism of TGF-β1+869(C/T) in allo-HSCT patients was closely related to the occurrence of severe aGVHD. The research show allo-HSCT patients with C/T genotype occurred severe aGVHD more frequently, which is an important potential risk factor to induce the incidence of severe aGVHD. Therefore,detecting gene polymorphism of TGF-β1+869 ( C/T ) in allo-HSCT recipients and developing the appropriate therapeutic regimen may be helpful to reduce the incidence of aGVHD.
