Objective To investigate the effects and possible mechanism of action of inhibiting hepatitis B virus X protein (HBx) expression on liver cancer metastasis. Methods The suppression of HBx expression in MHCC97H cells was performed by siRNA interference technique, and the effects of HBx suppression on the metastasis of MHCC97H cells were detected by Matrigel invasion assays and in a lung-metastasis mouse model. The expression levels of related epithelial-mesenchymal transition (EMT) and apoptosis proteins were examined by Western blotting. Results Introduction of HBx-siRNA into MHCC97H cells inhibited the expression of HBx and the ability to metastasize,downregulated the expression of Twist and N-cadherin, and upregulated E-cadherin expression. These changes resulted in inhibiting EMT of MHCC97H cells. Meanwhile, apoptosis involved in the Twist-P53 pathway was also found. Conclusions Inhibiting expression of HBx can decrease the metastatic a-bility of MHCC97H cells by changing EMT and inducing apoptosis.

BACKGROUND: Various etiological mechanisms are involved in cerebral infarction. Both free radicals and lipid peroxidation participate in the atherosclerosis and damage of neural cells after cerebral ischemia. Compound danshen(Radix Salviae Miltiorrhizae) is a common prescribed Chinese herb, acting on activating blood circulation and removing stasis for cerebral infarction and coronary heart disease, but its mechanism has been unknown in many aspects.OBJECTIVE: To observe the effect of compound danshen on neural function defect and free radicals in patients with cerebral infarction so as to probe into its possible mechanisms.DESIGN: A randomized controlled trial.SETTING: Neurological Internal Department of a hospital affiliated to one university.PARTICIPANTS: Totally 538 inpatients were collected in Neurological Internal Department of First Hospital affiliated to Jinzhou Medical College from February to December 2002, their diagnosis compiled with "Diagnostic Keys on Every Type Cerebral Vascular Disorders" adopted on the 4th National Acadenic Meeting on Cerebral Vascular Disorders, and determined by cerebral CT scan. All of those were the first attack of atherosclerosis cerebral infarction in 72 hours. The patients with cardiac infarction, heart failure, auricular fibrillation, insufficiency of liver and kidney function,hemorrhage of digestive tract, vascular dementia and bulbar paralysis and the patients who could not be well cooperated were not included. A total of 68 patients compiled with the standards, of which, 38 patients were male and 30 patients female, aged varied from 52 to 78 years, at the average of (64. 62 ±5.80) years. The patients selected were randomized into study group and the control by lot-drawing nethod according to the hospitalized sequence and volunteer principle of the control.METHODS: The basic treatment was same in two groups. In study group,compound danshen injection was added together with physiological saline 250 mL for intra-venous drip, once daily, continuous 14 days made one course. In the control, thrombosis removing injection 15 mL was added together with physiological saline 250 mL for intra-venous drip, once daily,continuous 14 days made one course.Level of serum lipoperoxide(LPO) and activity of superoxide dismutase (SOD).RESULTS: Statistical differences presented in declined scores of severity of neural function defect after treatment in two groups compared with their own controls(in study group: 28.62 ±6.76 vs 13.84 ± 8.16; in the control:28.58±7.05 vs 21.52±8.24, t=8.134, t=3.796 respectively, P＜ 0. 001 ). The score in study group was declined more obviously compared with the control after treatment, indicating very significant difference ( t = 3. 861, P ＜ 0. 001 ). The effective rate of compound danshen injection was 88.24% in treatment of cerebral infarction, which significantly superior to that in the control(67.65% ) (x2 =4.19, P ＜ 0.05). Compound danshen remarkably reduced serum LPO level[ (8.69 ± 1.28) nmol/L vs (5.86 ± 1.42) nmol/L, t =8. 628, P ＜ 0. 001 ] and statistical differences presented compared with the result in the control after treatment[(5.86±1.42) nmol/L vs(8.56±0.95) nmol/L, t=9.125, P ＜0.001] . Simultaneously, SOD activity in serum was significantly increased, [ (26. 25±4. 64) mkat/g vs(30. 01 ± 3.87) mkat/g, t = 3. 629, P ＜ 0. 001] indicating statistical differences compared with the result in the control after treatment[ (30. 01 ±3.87) mkat/g vs(26.33 ±4. 14) mkat/g, t =3. 778,P ＜ 0.001].CONCLUSION: Compound danshen improves significantly neural function defect in patients with cerebral infarction, with definite therapeutic effects on the treatment. It can reduce serum LPO content and increase serum SOD activity in patients with cerebral infarction. It is predicted that removing free radicals and anti-lipid peroxidation damage is probably one of the important mechanisms of it, which provides a further theoretic evidence for the treatment of cerebral infarction clinically.

Objective To investigate the differential expression profiles of microRNAs in the liver of 60Co γ-ray irradiated mice using microRNA microarray and to explore their main functions by bioinformatic analysis.Methods After SPF C57BL/6J mice expose to 4 Gy-single whole body radiation,total number of peripheral WBC and the fMNPCE were measured at 3 d.The differentially expressed miRNAs in mouse liver were detected with miRNA microarray,miRNA-124 and miR-34a were confirmed by real time RT-PCR assay.Bioinformatic analysis was applied to explore target genes and the main functions of the differential expressed miRNAs.Results Compared with control group,the total number of peripheral WBC decreased( t = 2.87,P ＜ 0.05 ) ,while the fMNPCE in bone marrow increased ( t =-2.91,P ＜0.05) after 4 Gy γ-ray irradiation.miRNA microarray revealed that 17 miRNAs were differentially expressed,in which 9 up-regulated,8 down-regulated.The expression levels of miR-124 and miR-34a were coincident with the result of real time RT-PCR.GO analysis showed that some pathways including adherens junction and cell cycle were suppressed,while some immune-related pathways were activated.Conclusions miR-34a and miR-194 were involved in the regulation of acute radiation damage,some other miRNAs including miR-124、miR-382 and miR-92a* also played important roles in radiation process.

Objective To improve patient postoperative comfort of vitrectomy with tamponnade in the prone position, design a new prone position headrest to reduce complications caused by improper body position and observe its clinical effect. Methods According to the postoperative position of the patients, 360 cases were collected. The patients were divided into the control group and the observation group with 180 cases of each group. Observation group was treated with the new prone position headrest nursing, control group were treated with routine prone position. The comfort of patients, postoperative adverse reactions, success rate of retina reattachment were observed. Results According to simplified comfortable situation scale, physiological, psychological, social culture and environment of each individual score respectively was (2.74±0.21), (3.54±0.29) , (3.25±0.23), (3.36±0.27) points in observation group and (2.30± 0.19), (2.92±0.31), (2.93±0.26), (2.79±0.30) points in control group, and there were significant differences (t=12.368-20.845, all P<0.05). The daily posture duration in postoperative first time and 5 days was respectively (220.00±25.08), (1008.00 ± 20.32) min in observation group and (85.00±28.07), (650.00± 30.12) min in control group, and there were significant differences(t=48.117, 133.194, all P<0.01). The incidence of corneal edema, conjunctival congestion, water turbidity in observation group were lower than those in control group at 4 weeks after surgery, and there were statistically significant difference (U=6.308,8.130, 6.875, P < 0.01). The incidence of high intraocular pressure, recurrent retinal detachment rate and reduction rate in observation group were lower than those in control group at 4 weeks after surgery, and there were statistically significant difference (χ2=9.000, 10.540, 11.770, P < 0.01). Conclusions The new prone headrest can effectively improve the resection of vitreous body with tamponade patients in comfort, ensure the operation effect.

OBJECTIVE: To investigate the expression of Wilms'tumor 1 () gene in patients with acute myeloid leukemia (AML), and to explore its application in predicting prognosis of AML in patients with wild or mutated nucleophosmin 1() and Fms-like tyrosine kinase 3-internal tandem duplication (). METHODS: One hundred and sixty-seven newly diagnosed AML patients(exclued M3 type) were enrolled in this study. The survival of patients were analyzed with Kaplan-Meier method. The clinical data, laboratory findings and the survival of patients were analyzed and compared between patients with high expression (high- group) and those with low expression (low- group), as well as among the patients with or wild type and mutants. RESULTS: The overall response rates (ORR) in high- and low- groups were 65.9% (83/126) and 95.1% (39/41), respectively (<0.01). Compared with the low- group, the high- group had lower 2-y overall survival (OS) rate (46.1% vs. 75.2%, <0.05) and 2-y disease free survival (DFS) rate (43.5% vs. 68.5%, <0.05). After induction chemotherapy, the patients with decreased gene expression ≥ 1log was associated with higher ORR and 2-y OS rate (all <0.05), but the advantage of 2-y DFS rate was not shown (>0.05). In patients with wild type, the high- group had inferior ORR and 2-y OS rate (all <0.05), while in the patients with wild type, the high- group had inferior ORR, 2-y OS rate and 2-y DFS rate (all <0.05). In patients with or FLT3 -ITD mutations, the expression had no significantly predicting values in treatment efficacy and survival (all >0.05). CONCLUSIONS gene overexpression indicated poor prognosis of AML patients; the patients with decreased gene expression ≥ 1 log after the first induction therapy show better prognosis than those with<1 log. The gene expression level at diagnosis can be used as an unfavorable prognostic factor for AML patients with or wild types.

Donation related vasovagal reaction(DRVR) is the most common adverse reaction during blood donation. It is very important for blood banks to identify, treat and prevent DRVR accurately. At present, it is generally believed that psychological factors are the first major inducement of DRVR. Applied muscle tension (AMT) and salt supplementation have been proved to be effective interventions for vasovagal response; the identification methods of high-risk groups such as State Trait Anxiety Inventory, Medical Fear Inventory and Blood Donor Response Scale have been relatively mature, but the utilization rate is relatively low in China. In this paper, the main clinical manifestations, pathogenesis, research methods, related factors, management and prevention measures of DRVR, as well as the identification of high-risk groups before blood donation are reviewed.

Objective: To determine the value of hyperextension MRI evaluation in determining whether to perform decompression therapy after reduction of reducible atlantoaxial dislocation as well as assess the decompression effect. Methods: A retrospective case series study was conducted to analyze 24 patients with atlantoaxial dislocation admitted to Honghui Hospital affiliated to Xi'an Jiaotong University from May 2015 to May 2017. There were 10 males and 14 females, aged 40-74 years, with an average age of 52 years. There were 14 patients with os odontoideum, four patients with odontoid fracture, and six patients with transverse atlantal ligament rupture. Hyperextension MRI was performed to assess spinal cord compression for all patients. Eight patients with anterior spinal cord compression (Group A) underwent posterior atlantoaxial arch decompression plus atlantoaxial internal fixation reduction and bone graft fusion; 16 patients without anterior compression of the spinal cord (Group B) underwent only atlantoaxial internal fixation reduction and bone graft fusion. Intraoperative and postoperative complications were recorded. Spinal cord compression index and improvement rate of spinal cord decompression were evaluated by routine cervical spine MRI. Japanese Orthopedic Association (JOA) score was used to evaluate the clinical effect. Results: All patients were followed up for 3-24 months, with an average of 9.3 months. There was no nerve or vertebral artery injury during the operation, and no screw loosening occurred after surgery. The spinal cord compression index (0.37±0.18) in Group A at the last follow-up was significantly lower than that before operation (0.73±0.22) (P<0.05), while the index in Group B (0.19±0.20) at the last follow-up was also lower than that before operation (0.61±0.25) (P<0.05). The improvement rate of spinal cord decompression was 67.11% in Group A and 70.61% in Group B. The final JOA score of Group A was (13.29±3.68)points, which was significantly better than the preoperative JOA [(5.61±2.74)points] (P<0.05). The final JOA score in Group B [(14.13±3.45)points] was also significantly better than the preoperative JOA [(7.32±2.90)points] (P<0.05). Improvement rate of JOA was 57.31% in Group A and 59.91% in Group B. Conclusions Hyperextension MRI of cervical vertebra can effectively judge whether the anterior spinal cord is compressed after reduction of atlantoaxial dislocation. It has important clinical significance for decompression treatment during reduction and internal fixation of reducible atlantoaxial dislocation. At the same time, posterior atlantoaxial arch resection and decompression can effectively relieve the compression of the spinal cord after reduction of atlantoaxial dislocation.
