The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.

Objective To investigate the effect of propofol on nNOS expression after focal cerebral ischemia-reperfusion in rats and the possible mechanism of protective effect of propofol on brain. Method Seventy-eight male Wistar rats, weighting 250 ~ 300 g, were randomly divided into 3 groups:(1)Sham operation group (S group, n=6) was performed with scham operation; (2) Ischemia-reperfusion group (group I-R, n=36) was subjected to 2-hour right middle cerebral artery occlusion and then reperfusion was followed, saline (1 mg/kg) was injected into the right lateral cerebral ventricle using microsyringe before reperfusion;(3) Propefol group (group P, n=36) was injected with propofol (1mg/kg) into the right lateral cerebral ventricle using microsyringe right after ischemia. Group I-R and group P were divided into 3 subgroups according to the reperfusion time: 1 h, 3 h and 6 h. The neurological function of all rats were tested before reperfusion. The cerebral infarction area of the whole brain was calculated with TIC staining (n=6). The pathological change of brain was observed from HE staining (n=6) and the nNOS protein expression was obtained by immuno- histochemical method (n=6). Results Compared with I-R group, the neurological function was better in group P(P

Objective:To evaluate the effect of percutaneous coronary intervention(PCI) on mitral regurgitation(MR) in patients with acute myocardial infarction(AMI).Methods: A total of 213 AMI patients were divided into PCI group(n=87,(PCI +) medication) and medication group(n=126,medication) according to the treatments they received.Echocardiographic examination was conducted in patients during admission and 6 months follow-up.Color Doppler was used to determine the degree of MR.Echocardiogram indices included MR degree,left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVEDs),left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),and left ventricular ejection fraction(LVEF).Results: The overall incidence of MR was 28.6% in 213 patients during admission.The MR incidence in patients with acute inferior myocardial infarction was higher than that in patients with other parts of infarction((34.5%) vs 22.3%,P0.05),while the incidence in medication group increased significantly than that during admission(43.7% vs 30.2%,P

OBJECTIVE: To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims. METHODS: Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed. RESULTS: MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries. CONCLUSION A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.

Objective:To develop a novel regulable sutureless aortic arch prosthesis and to apply it in an animal experimental study.Methods:The arch skeleton of the prosthesis was made of tandem Z-shape NiTiNOL wire;the branch skeleton was made of laser-cut NiTiNOL tube;and the whole skeleton was coated with thin ePTFE film.The blood vessel was anastomosed by di- rect ligature,needing no manual suturing.The prosthesis was applied in swine aortic arch operations under the bypass condi- tion.The practicality for surgery and the feasibility of anastomosis of the prosthesis were assessed.Results:Aortic arch opera- tions were successfully performed in 6 of the 8 experimental animals.The prostheses were easy to use,and the mean bypass time was only 10 min.The blood loss of the anastomoses was less than 100 ml within 8 h postoperatively in 5 animals;one had more blood loss due to prosthesis mismatch.Conclusion:The novel regulable sutureless aortic arch prosthesis has satisfactory practicality for surgery and reliable anastomosis,making it promising in future clinical application.

This article analyzed the medical records of a patient with 90% TBSA unhealed wound accompanied with wound sepsis 50 days post burn (PBD) and to discuss the ideal strategies of treatment for such patients in such condition. This was a 24-year-old male patient suffering from flame burn with 95% TBSA wound and severe inhalation injury. Meek skin grafting with autologous scalp was performed once to the thoracic and abdominal regions; intermingled skin grafting of autologous scalp microskin and large sheet of allograft was performed twice to the limbs within PBD 31. The patient was transferred to our hospital on PBD 50 with 90% TBSA wound unhealed, leaving a vast amount of necrotic tissue and allografts. Furthermore, he was complicated by sepsis, pulmonary infection, and gastric ulcer. Debridement and allogenic skin grafting were performed on the first day after hospitalization. When the condition of wounds was improved, transplantation of a large sheet of allogenic skin with inlaid small pieces of autologous skin, intermingled skin grafting of autologous and allogenic skin, and small pieces of autologous skin grafting were performed. Because of the shortage of donor area, the exposed wounds were temporarily covered with allogeneic skin. Epidermal growth factor was used to promote the healing of autologous skin donor site and deep partial-thickness burn wound. Autologous skin grafting was performed whenever source of healthy skin was available. Systemic use of effective antibiotics, nutritional support and therapy, and other comprehensive measures also contributed to the success of treatment of this patient suffering from wound sepsis. The patient was cured and discharged on PBD 145.

The dry seeds of Cassia obtusifolia were carried by the "ShenZhou 8" satellite and sowed after landing. Based on our pri- or study on SP1, the characteristics of plants growth, physiological index and content of effective components were examined. The results showed that the QC10, QC29 strains matured 5 d earlier compared with control. The plant height, across diameter and ground diameter of QC10, QC29, QC46 strains was superior to the control at whole growth period. The branch number increased ranging from 4 to 11 and the number of pods reached 321, 313,281, respectively, which was dramatically higher than the control (246). The yield of QC10, QC29, QC46 strains increased noticeably from 31.4 to 63.2 g. The 1000-seed-weight of QC10, QC29, QC46 strains was 25.86, 25.88, 24.06 g, while the control was 23.69 g. Compared to the control, the mass fraction of chlorophyll was enhanced 1.098, 1.016, 0.297 mg. There was no significant difference in aurantio-obtusin and chrysophanol content of seeds. Through two years research, three high-yield mutant strains were obtained. This study indicates that spaceflight-induced mutants could provide new germplasm for C. obtusifolia breeding and offers the theoretical basis for further utilization of spaceflight-induced mutation to breed high-quality C. obtusifolia strains.
