Using GAD immunohistochemical PAP technique and microcomputer image analysis system, we have studied on the substantia nigra of rat epilep- tic model induced by Coriaria Lactone and discovered that in the early experi- mental group and 6 hour group, the intensity of GAD-reactivity of nerve fibers and terminals was weaker and the area density of GAD-positive nerve fibers and terminals was lower than those of control group (P

Objective To investigate the clinical value of CT scanning combined with ultrasound technique in diagnosis of malignant bone tumor.Methods 100 patients with malignant bone tumor were randomly divided into control group(50 cases with CT scan),and observation group (50 cases received CT scanning combined with ultrasound technology).The diagnostic accuracy rate,tumor bone formation and destruction of bone,periosteal reaction and soft tissue mass were compared between the two groups.All results were judged by the results of MR.Results Diagnostic accuracy rate of the observation group was 80.0％ (40/50),which was significantly higher than 64.0％(32/50) in the control group (x2 =4.65,P ＜ 0.05).In observation group,diagnosis of bone destruction in 60 cases,the tumor bone formation 10cases,83 cases of periosteal reaction and soft tissue mass in 40 cases,those in the control group were 40 cases,5 cases,62 cases,30 cases,the differences between the two groups were statistically significant(x2 =4.86,5.71,6.21,5.22,all P ＜ 0.05).Conclusion The combination of CT and ultrasound in the diagnosis of malignant bone tumors had high diagnostic accuracy rate,and could guide clinical treatment.

Background and purpose:In China, incidence of gastric cancer is high but early diagnosis is low and treatment results remains poor.The role of neoadjuvant chemotherapy for patients has been explored.In this study, we evaluated the effects and safety of preoperative intra-arterial infusion chemotherapy(PAIC) for advanced gastric cancer.Methods:One hundred and five patients with clinic stage-Ⅱ above advanced gastric cancer were submitted to preoperative intra-arterial infusion chemotherapy using the Seldinger technique.The regimen consisted of 5-FU 750 mg/m2, MMC 10 mg/m2, and DDP 60 mg/m2.Seven to ten days after the PAIC, all 105 patients received operation.Other 95 patients underwent surgery directly as control group.The responses by the tumor lesion and chemotherapy toxicity were observed.The long term survival rate were also evaluated.Results:Pathological examination showed that the tumor cells had changed by chemothrapy.Common adverse effects of PAIC were grade Ⅰ-Ⅱ gastrointestinal discomfort and bone marrow depression.No gastric rupture had occurred.Ninety-one cases(86.6%) underwent curative resection.The 1, 3, and 5-year survival rate was 96.2%, 68.6%, and 52.4% respectively.Among 95 patients with control group, sixty-five cases(68.6%) underwent curative resection.1,3,and 5-year survival rates were 88.4%,38.9% and 28.4%,respectively.Conclusion:PAIC is an effective, and safety chemotherapeutic treatment for advanced gastric cancer.It can affer treatment downstage of disease and enhances resectability.It may also improve the prognosis of advanced gastric cancer.

Objective To investigate the influence of elastic band resistance training on cardiac function in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).Methods 64 hospitalized patients with acute myocardial infarction after PCI from January 2016 to June 2016,were randomly divided into two groups:rehabilitation group (n=30) and control group (n =34).The control group received a routine treatment and guidance,rehabilitation group received elastic band training as add-on therapy to above routine treatment and guidance.After 6 months of therapy,cardiac function,the number of daily chest discomfort and its duration were compared between two groups.Results After six months of therapy,6MWT [(530.9 ± 39.9) m versus (328.3±26.8)m,(t=24.104,P＜0.01)]and LVEF ≥50％ [n(％)] (83.3％ versus 50％)(x2 =7.850,P＜ 0.01)were significantly higher in the rehabilitation group than in control group,with statistically significant difference (t =24.104,x2 =7.850,all P ＜ 0.01).In addition,an average number of daily chest discomfort (x2=11.563,P＜ 0.01) and its duration (x2=9.067,P＜ 0.05) were obviously improved in rehabilitation group than in control group,with statistically significant difference.Conclusions Anti-resistance training can significantly improve the cardiac function of patients with acute myocardial infarction after PCI and can be applied in clinical practice.

Objective To analyze the quality of life(QOL)of patients with acute stroke,and to explore the effects of early specialized rehabilitation on their QOL.Methods Seventy patients with acute stroke were randomly divided into a rehabilitation group(n =35)and a control group(n =35).The rehabilitation group received specialized rehabilitation treatment while the control group received self-rehabilitation.QOL we evaluated with the short form-36(SF-36)instrument before and after.Results Before treatment,QOL scores in the both groups were much lower than the norms for healthy people.The differences on each dimension of the SF-36 were not statistically significant between the two groups.The SF-36 scores of both groups improved during the experiment,but after 1 month and 6 months the improvement on each SF-36 dimension was significantly better in the rehabilitation group than in the control group.Conclusions The QOL of patients with acute stroke is significantly impaired,but specialized rehabilitation treatment is effective in improving it.

Objective To investigate the changes of non-linear dynamics properties of EEG under different mental tasks,and the application of non-linear dynamic analysis for cognitive function research. Methods EEG was recorded in 30 healthy university students under four states: eyes closed,eyes open,mental arithmetic with eyes closed and graphic reasoning test with eyes open.Correlation dimension (D 2) and point-wise correlation dimension (PD 2) were calculated for all subjects.We also performed a surrogate data test in 5 randomized selected subjects. Results In all states tested,the results argued for the presence of non-linearity and fractal D 2 and PD 2.D 2 and PD 2 increased significantly during mental tasks as compared to the rest states (D 2 of above four states was 3.93,4.47,4.33 and 4.98 respectively).The results showed that values of D 2 and PD 2 fluctuated with time,which suggests an intermittent activation of the brain areas participated in the task.With non-linear dynamic analysis,there might be a working circuit from bilateral temporal lobes to the left frontal lobe and parental lobe under mental arithmetic task.Conclusions Through dynamic analysis based on D 2 and PD 2 topographic maps,we can see clearly the distribution of D 2 and PD 2 in the brain,the sequence and the degree of activation of the regions involved in the cognitive task under mental tasks.Dynamic and short-time non-linear analysis methods are more appropriate for the study of mental functions.Non-linear dynamic analysis might help us understand the working mechanism of brain during mental activities.

Gemcitabine is important pyrimidine antimetabolites drug. Ribonucleotide reductase is oneof its targets whose overexpression has been observed in several gemcitabine- resistant cell lines. Meanwhile,the NSCLC patients with high RRM1 expression levels have a relatively poor survival when treated with gem-citabine. To this day, the relationship between RRM1 expression levels in peripheral blood mononuclear cellsand gemcitabine is still uncertain and it deserves further research.

This paper introduced the function of assistive device, discussed the necessity of setting up assistive service security system from the perspective of human right, social civilization, government duty, social security, in-dustry.

Microcirculation disturbance and ischemia of the pancreas are important pathophysiological changes in the onset of acute pancrea-titis,and organ hypoperfusion is a risk factor for poor prognosis.During the first 12 to 24 hours after admission,fluid resuscitation is the most important medical treatment for the early stage of acute pancreatitis,and timely and rational fluid infusion helps to improve prognosis. However,there lacks high -quality clinical evidence for type of fluid,infusion speed,and monitoring methods,and more randomized con-trolled trials are needed.
