Objective To observe and compare the anti-angiogenic effect of sorafenib, unfractionated heparin(UFH)and low molecular weight heparin (LMWH), singly used or in combination, with chick chorioallantoic membrane assay. Methods Sixty 8d-developed chick embryos were randomly divided into 6 groups (10 each): control group, sorafenib group, UFH group, LMWH group, sorafenib+UFH group, and sorafenib+LMWH group. Drugs were given respectively and incubation continued. The dosage of drugs for each embryo was 20 nmol of sorafenib, 5U of UFH and 5U of LMWH, respectively, and H-DMEM was applied to the embryo in control group in the same volume (2?l). After continuing incubation for another 72h, the anti-angiogenic effect in each group was observed and the vascular number in the chick chorioallantoic membrane was counted. Results Vascular number in single drug groups (sorafenib group: 8.9?1.9; UFH group: 7.6?2.3; LMWH group: 6.9?1.3) was significantly smaller than that in the control group (26.8?2.3, P

Objective To study the changes of diamine oxidase (DAO )and intestinal fatty acid binding protein (I-FABP)levels in neonates with hypoxic-ischemic encephalopathy treated with selective brain hypothermia.Methods Collect a sample of 60newborns with moderate and severe hypoxic-ischemic encephalopathy who were hospitalized in the NICU of Matemal and Child Health Care Hospital of Baoding from June 2013to December 2014.The 60newborns were divided into two groups randomly:hypothermia group(n=30)and conventional treatment group(n=30).Selected 30cases hospitalized at the same period, except the related to the ischemia hypoxia and gastrointestinal dysfunction disease as the control group.The levels of serum levels of DAO and I-FABP were measured by ELISA on admission and 7days after treat-ment,respectively.And the score of gastrointestinal dysfunction were compared.Results Neither the levels of DAO and I-FABP in hypothermia group and conventional treatment group had statistical differences on ad-mission[DAO:(15.77±2.04)U/ml,(15.81±1.85)U/ml,P﹥0.05;I-FABP:(310.01±46.43)ng/L, (301.12±38.61)ng/L,P﹥0.05],but were higher than that in the control group [(7.65±0.74)U/ml, (51.65±6.91)ng/L].Seven days after treatment,both the levels of DAO and I-FABP of hypothermia group and conventional treatment group decreased [DAO:(7.88±1.87)U/ml,(12.51±1.53)U/ml;I-FABP:(59.16±6.17)ng/L,(121.31±21.54)ng/L],meanwhile,the variation of hypothermia group was more significant(P﹤0.05).The correlation of the plasma DAO and I-FABP levels and the score of gas-trointestinal dysfunction was significantly (r1=0.831,r2=0.827,P ﹤0.01).Conclusion Hypothermia treatment could effectively reduce the levels of DAO and I-FABP,thus improve the gastrointestinal function in some extent.

Objective To explore the differences of the proliferation ability and the antineoplastic activity of CIK cells against origenal hepatocellullar cancer cells between healthy adults and tumor patients in vitro. Methods Peripheral blood mononuclear cells (PBMC) from healthy donors and tumor patients were incubated to induce CIK cells in the presence of interferon gamroa(IFN-γ) ,IL-2 and anti-CD3 monoclonal antibody (mAb). The changes in the proliferation activity and phenotypes of the CIK cells were identified by flow cytometric analysis. Single cell suspension was prepared bom the fresh hepatocellular carcinoma tissue by using mechanical trituration method. MTT assays were used to determine the cytotoxicity of CIK cells against origenal hepatocellullar cancer cells. Results The CIK cells from both healthy donors and tumor patients were significantly increased with the extension of time. The expression rate of CD3+/CD56+ cells from healthy donors rose from 1.053% ±0.22% on 1st day ,25.36% ±2.19% on the 7th day to 55.12% ±1.99% on the 14th day ,which was significantly higher than that of tumor patients ( P ＜ 0.05). MTT assays showed that the cytotoxicity of CIK cells from both enhanced obviously with the addition of Effect/Target rate and extension of time(P ＜0.05). After the origenal hepatocellullar cancer cells were treated by CIK cells 24 hours, the cytotoxicity of CIK cells from healthy donors at the effector:target ratio of 10 ∶ 1,20 ∶1 and 40 ∶1 was significantly higher than that of tumor patients(P＜0.05) ,respectively. After treated 48 hours, compared with tumor patients, the cytotoxicity of healthy donors? CIK at the three effector:target ratio was alsosignificantly higher(P ＜0.05), respectively. Conclusion CIK cells from both have amplification ability and cytotoxic activity in vitro,and the proliferation ability and killing activity of healthy adults CIK is stronger than that of tumor patients,which provides an experimental basis for CIK to clinical application as an adoptive immunotherapy.

Objective　To study anticipated value of the retention rate of indocyanine green at 15 minutes after injection (ICGR15) and oral glucose tolerance test (OGTT) on hepatic function reserve in patients with primary hepatic cancer (PHC). Methods　58 patients with PHC were divided into 3 groups according to the recovery after operation for PHC. Of them, 29 cases showed good recovery (group A), 18 mild liver dysfunction (group B) and 11 severe liver dysfunction (group C) respectively. ICGR 15, OGTT, routine liver function tests were performed in all 　patients preoperatively. Results　　ICGR15 in group C(24.17%±6.59%) obviously increased than that in group A(11.42%±3.91%,P<0.01) and in group B(16.28±6.07%, P<0.01). 　Blood glucose lever of 120 min after glucose loading test in group C (9.91 mmol/L±3.09 mmol/L)was significantly higher than that in group A(5.42 mmol/L±0.83 mmol/L, (P<0.01)and group B(6.68±1.61, P<0.01). 　The accuracy (81.0%,86.2%), positive (90.6%, 93.5%) 　and negative prediction value (72.5%, 74.4%) of OGTT and ICGR 15 were respectively significent greater than those of Pugh's scoring (P<0.01).Conclusions　ICGR15 and OGTT are worthwhile indicators to assess hepatic function reserve for patients with PHC. Combination of both ICGR15 and OGTT has higher predictive value on hepatic function reserve.

Objective To evaluate the method and clinical effect of subtalar joint distractor assisted open reduction and internal fixation of comminuted intra-articular calcaneal fracture.Methods Twenty-two patients with fresh closed calcaneal fracture treated with open reduction and internal fixation from May 2011 to July 2013 were included in the study.According to the modes of operation,the patients were randomly divided into two groups (n =11 in each):in group A patients underwent fracture reduction assisted by subtalar joint distractor and in group B patients underwent Steinmann pin traction and poking reduction.All were fixed using the lateral calcaneal plate.Operation time,B(o)hler angle,Gissanes angle,calcaneus height,incision healing time and complications of the two groups were investigated for evaluating the effect of operation.Clinical effect was evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) score before the removal of internal fixation.Results Period of follow-up was (14.3±0.8)months (range,12 to 18 months).Two patients in group B had delayed wound healing,and were treated with regular wound care.At the final follow-up,no infection,nonunion,malunion and internal fixation failure were observed.B(o)hler angle,operation time and calcaneus height observed in group A were superior to those in group B (P ＜0.01).There was no significant difference in Gissanes angle between the two groups (P ＞ 0.05).Compared to the preoperative data,B(o)hler angle,Gissanes angle and calcaneus height were significantly improved in both groups (P ＜0.01).AOFAS score was (83.6 ± 1.4) points in group A and (81.7 ± 1.5) points in group B.Conclusion Subtalar joint distractor assisted open reduction and internal fixation is effective to shorten operation time,improve fracture reduction,reduce wound complications and increase the operative effect for comminuted intraarticular calcaneal fracture.
