METHODS:In retrospective study,64 ACI patients were divided into group A(Ginkgo dipyidamolum+edaravone,22 cases),group B(argatroban+edaravone,19 cases)and group C (sodium ozagerl+edaravone,23 cases). Therapeutic efficacies were observed after 7-14 days of treatment;therapy cost was calculat-ed,and cost-minimization analysis was used to evaluate pharmacoeconomics. RESULTS:There was no statistical significance in to-tal effective rate among 3 groups(P>0.05);the costs of group A,group B and group C were 8 746.36 yuan,10 770.64 yuan and 8 264.67 yuan. Results of sensitivity analysis were in line with those of cost-minimization analysis. CONCLUSIONS:Therapy plan of sodium ozagerl+edaravone is the economical regime in the treatment of ACI .

Objective To study the relationship of the university students' procrastination and big five personality factors.Methods 461 university students were assessed by the simple edition of tuckman procrastination scale(TPS) and the big five personality inventory short form(NEO-FFI).Results TPS score of the student was (48.51 ± 7.66).There were 89.4% students respectively had different level of procrastination behavior.There were no significant differences in university students by the gender(47.95 ±7.84 vs 48.95 ± 7.43 ) ,whether one-child students(48.64 ± 7.49 vs 48.45 ± 7.81 ) and grades.There were significant positive correlation between procrastination and the personality factor of neuroticism( r=0.235, P＜0.01 ) and significant negative correlation with extraversion ( r=-0.180, P ＜ 0.01 ) and conscientiousness ( r =-0.198, P ＜ 0.01 ).The big five personality factors of neuroticism,extraversion and conscientiousness could explain the 14.0% variation of procrastination of university students.Conclusion Procrastination is a very common phenomenon in the university students.The students with higher neuroticism, lower extraversion and conscientiousness of big five personality have more procrastination behavior.

Aortic dissection is a common disease which is very dangerous,with high mortality rate.Bypass graft for the treatment of DeBakey Ⅲ dissection has outstanding advantages than the ordinary replacement of thoracic aorta,and some patients will inevitably require the use of the procedure.The purpose of this study was to explore the impact of the subclavian artery-abdominal aorta bypass graft on hemodynamic parameters in the false lumen and the effectiveness of surgical treatment.First of all,the idealized three-dimensional geometric models of DeBakey Ⅲ aortic dissection and its subclavian artery-abdominal aorta bypass graft operation were constructed,respectively.Then the models were imported into ANSYS 11.0 for finite element analysis.Results of numerical simulation showed that both velocity and pressure of the blood flow were reduced after bypass graft at the entrance and in the internal sac of false lumen,which is very favorable for reducing the impact of blood flow on false lumen,slowing down the further expansion of entrance,preventing the breakdown of false lumen,and promoting the healing of dissection.Therefore,the subclavian artery-abdominal aorta bypass graft operation is an effective surgical method for the treatment of DeBakey Ⅲ aortic dissection in some particular cases.This operation is with great prospects for clinical application.

Objective To observe the effect of intermedin (IMD) preconditioning on cyclin D1, cyclin E and CDKs expression, and explore its role in.promoting kidney tissue regeneration after renal ischemiareperfusion injury. Methods One hundred and forty-four healthy male Wistar rats were randomly divided into four groups: sham operation (S) group, ischemia-reperfusion injury (IR) group, empty plasmid (EP) group and IMD group. In the IR group, after the right kidney was excised, the aorta abdominalis and left renal artery were bluntly dissected in EP and IMD group, empty plasmid and IMD plasmid were transfected into the left kidney using ultrasound-micro-bubble (SonoVue) mediated system, respectively. One week later, renal IRI model was made by clasping the left renal artery for 45 min. After 1, 2, 3, 4, 7 and 14 day of reperfusion, the kidney in each group was collected to detect the expression of cyclin D1, cyclin E, CDK4 and CDK2 by western blot analysis or enzyme-linked immunosorbent assay (ELISA). Results Compared with S group, the expression of cyclin D1, cyclin E, CDK4 and CDK2 was significantly up-regulated in day 1, 2,3, 4, 7 and 14 in IR group. And the above index increased gradually after reperfusion, and reached the peak at day 7 (F=54.92, 69.60, 61.28, 77.38, P＜0.05). While in IMD group, these indexes reached the peak at day 1, then progressively declined, and could not be detected at day 14 (compared with the IR group, F=54.92, 69.60, 61.28, 77.38, P＜0.05). Conclusion IMD preconditioning can up-regulate the expression of cyclin D1, cyclin E, CDK2 and CDK4 in the early phase of renal ischemia-reperfusion injury that may accelerate repair of renal tissue, at least by part, by enhancinge cell proliferation.

Objective:Concentrated growth factors (CGF),a new generation of platelet concentrate products,appears to have more abundant growth factors because of its special centrifugation process.However,there are few studies supporting this.This study was designed to evaluate the effect of CGFs in the treatment of Ⅱ ° furcations of mandibular molars.Methods:In the present study,thirty-one Ⅱ ° furcation involvements in twenty mandiblular molars were included and randomly divided into two groups.The furcation involvements in the experimental group were treated with bone graft therapy combined with CGFs,and the furcation involvements in the control group were treated with bone graft therapy alone.The clinical examination and cone beam computed tomography (CBCT) were performed at baseline and 1 year post-surgery for the two groups.The changes of clinical and CBCT data at baseline and 1 year postsurgery were compared between the experimental group and the control group.Results:At baseline,there were no significant differences between the two groups in the probing depth (PD),vertical clinical attachment loss (CAL-V) and horizontal clinical attachment loss (CAL-H):PD (7.36 ± 2.32) mm (the experimental group) vs.(7.53 ±2.06) mm (the control group);CAL-V (8.69 ± 1.65) mm (the experimental group) vs.(8.81 ±1.53) mm (the control group);CAL-H (5.24 ±2.01) mm (the experimental group) vs.(5.35 ±2.14) mm (the control group).At the end of 1 year post-surgery,the clinical parameters of both groups were significantly improved (P ＜ 0.001).For the experimental group,the average vertical attachment gain was (2.78 ± 1.66) mm,and the vertical attachment loss was improved significantly compared with the baseline (P ＜ 0.001);the average horizontal attachment gain was (2.10 ± 1.89) mm,and the horizontal attachment loss were improved significantly compared with the baseline (P ＜ 0.001).Furthermore,the improvement degree of the experimental group was significantly higher than that of the control group (P ＜ 0.001).At baseline,there were no statistical differences in the vertical bone loss (BL-V) or horizontal bone loss (BL-H) between the two groups (P ＞ 0.05):BL-V (5.08 ± 2.17) mm (the experimental group) vs.(5.84 ± 2.65) mm (the control group);BL-H (5.85 ±2.13) mm (the experimental group) vs.(6.01 ±2.27) mm (the control group).At 1 year post-surgery,both groups showed significant radiographic bone gain at vertical and horizontal directions compared with baseline (P ＜ 0.001).For the experimental group,the average vertical radiographic bone gain was (2.20 ± 1.98) mm,the horizontal radiographic bone gain was (2.51 ±2.18) mm,the vertical and horizontal radiographic bone loss were both significantly reduced compared with the baseline (P ＜ 0.001).For the control group,the average vertical radiographic bone gain was (1.89 ± 2.15) mm,the horizontal radiographic bone gain was (1.30 ± 2.47) mm,the vertical and horizontal radiographic bone losses were both significantly reduced compared with the baseline (P ＜ 0.001).And the experimental group showed significantly higher bone gain at vertical and horizontal directions compared with the control group (P ＜ 0.001).Conclusion:Within the limitation of the present study,CGFs showed positive role in the treatment of Ⅱ° furcation involvements of mandibular molars.

ObjectiveTo study the mechanism of differentiation of mesenchymal stem cells(MSCs) into neuron-like cells in vitro.MethodsMSCs of Wistar rats were separated and cultured, and then induced with DMSO and BHA in vitro. The specific marking proteins of neurons, glia and neural stem cells were detected before preinduction, at 24h after preinduction, at 6h, 24h, and 48h after neuronal induction.ResultsAfter the inducement, many MSCs turned into bipolar,multipolar and taper,and then intersected as network structure. Nestin was strong positive at 6h after neuronal induction, and decreased at 24h, 48h after the induction. NeuN was present at 6 h after neuronal induction, and increased at 24h, 48h after the induction.ConclusionMSCs can be induced into neural stem cells(NSCs) at first, and then differentiate into neuron-like cells in vitro.

Objective:To observe the effect of acupuncture combined with vitamin B12 point injection on pain severity in patients with discogenic low back pain and to analyze its potential mechanisms. Methods:A total of 96 patients with discogenic low back pain were randomly divided into two groups.The control group received acupuncture treatment,while the combined group received vitamin B12 point injection in addition to the identical acupuncture treatment in the control group.Both groups were treated for 2 weeks.The visual analog scale(VAS)and Oswestry disability index(ODI)scores were compared before treatment,after 1 week of treatment,and after 2 weeks of treatment.The levels of such serum inflammatory factors as tumor necrosis factor(TNF)-α and interleukin(IL)-6,serum beta-endorphin(β-EP),and prostaglandin(PG)E2 were compared before and after treatment.Adverse reactions and clinical efficacy were compared between the two groups after treatment. Results:The total effective rate in the combined group was higher than that in the control group(P<0.05).The VAS and ODI scores in the combined group after 1 week and 2 weeks of treatment were lower than those in the control group at the same time point(P<0.05).The levels of TNF-α,IL-6,and PGE2 in the combined group were lower than those in the control group after treatment(P<0.05),while the level of β-EP was higher than that in the control group(P<0.05).There was no statistical difference in the overall incidence of adverse reactions between the two groups(P>0.05). Conclusion:Acupuncture combined with vitamin B12 point injection can alleviate pain and promote functional recovery in patients with discogenic low back pain;reducing the levels of TNF-α,IL-6,and PGE2 and increasing the level of β-EP may be part of the mechanism of the therapy.

OBJECTIVE: To investigate the effect of serglycin knockdown on the sensitivity to cisplatin in nasopharyngeal carcinoma highly metastatic cells. METHODS: Stable transfected nasopharyngeal carcinoma highly metastatic cell lines was established. The alteration of serglycin expression was examined by qRT-PCR and Western blot assay established. The IC50 of cisplatin in stable cells were measured by MTT assay. The effect of serglycin knockdown on the proliferation of stable cells treated with cisplatin were measured by MTT assay. Colony formation assay were used to show cloning capacity. Annexin V/PI staining were used to detect apoptosis. qRT-PCR analysis was performed for stem cell-associated genes in stable cells. RESULTS: Stable transfected cell lines were successfully established and cellular morphology of stable transfected cells were changed. When treated with cisplatin, the IC50 and the colonies of serglycin knockdown cells were significant lower than controlled cells, however, the inhibition of proliferation and the percentage of apoptosis were significant higher than controlled cells. The stem cell-associated genes were reduced in serglycin knockdown cells. CONCLUSION: Stable interference of serglycin makes nasopharyngeal carcinoma highly metastatic cells more sensitive to cisplatin.

Objective To investigate the value of narrow band imaging(NBI) in diagnosis of early gastric cancer(EGC) and dysplasia. Methods 217 patients were enrolled. Routine endoscopy followed by narrow band imaging (NBI), then chromoendoscopy (indigo carmine) combined magnifying endoscopy was sequentially used. The gastric pits and microvasculuture were carefully observed. According to the NBI ima-ges, the biopsy samples were taken in suspicious area to identify malignant and premalignant gastric lesions. The patients with gastric cancer or severe dysplasia required endoscopic uhrasonography(EUS), then EGC or severe dysplasia ones needed endoscopic therapy or surgery. Results In silhouette of gastric lesion, NBI is the clearest in the above three endoscopic methods. Both mucosal pit and epithelium capiUary were shown much clearer by NBI than by routine endoscopy. Of 217 patients, 19 cases of mild dysplasia, 9 cases of moderate dysplasia, 4 cases of severe dysplasia and 5 cases of EGC were finded according to histopathological diagnosis. Six patterns of gastric pits were summarized by NBI. Dysplasia usually behaviored as V1 or Ⅳ gastric pits,and Ⅵ mucosal pit were suspected malignant lesion. Tumorous vessels can be seen in 3 cases of EGC. Conclusion By narrow band imaging system with magnifying endoscopy, the micro gastric mucosal structure can be shown much clear. That is helpful for improving the accuracy of malignant lesion on endo-scopic target biopsies and finding early gastric cancer.

Objective To investigate the diagnostic values of imaging techniques and endoscopy in detection the causes of post-hepatic obstructive jaundice.Methods The clinical data of 57 patients with post-hepatic obstructive jaundice were retrospectively studied.The causes of the obstruction and the findings of uhrasonography(US),computerized tomography(CT),magnetic resonance imaging(MRI)or MRIcholangiopancreatography(MRCP),endoscopic retrograde cholangiopancreatography(ERCP)and endoscopic ultrasonography(EUS)were compared.Results The causes of 57 patients with post-hepatic obstruetive jaundice were benign obstruction in 42(including stones in common bile duct in 38,ascariasis of CBD in 1,postoperative stricture in 2 and chronic pancreatitis in 1),and malignant lesions in 15(including pancreatic head carcinoma in 11 and ampullary carcinoma in 4).The diagnostic accuracy in terms of lesion location of US,CT,MRI+MRCP,ERCP and EUS were 71.93%(41/57),88.00%(22/25),94.59% (35/37),100.00%(47/47)and 96.77%(30/31),respectively;the diagnostic accuracy of cause of obstruction were 63.16%(36/57),80.00%(20/25),83.78%(31/37),100%(47/47)and 96.77% (30/31),respectively.Conclusion Benign diseases are the main causes of post-hepatic obstructive jaundice,but malignant ones are not rare.It is important to combine miscellaneous imaging techniques and endoscopy in diagnosis.
