Aim To observe the c-fos expression in the caudate-putman of 6-OHDA-lesioned rats after Apomorphine intraperitoneal injection and to investigate the inherent mechanism of it. Methods Rats received a unilateral injection of 6-OHDA into SNc. The abnormal rotations induced by Apomorphine (APO) were investigated 1、7、14 d and 21 d after lesion.Meanwhile dopaminergic derogation and c-fos expression were observed with Nissl body staining,eletronicmicroscopic and immunocytochemistry methods. Results The number of dopaminergic neurons decreased gradually in the lesioned site and its eletronicmicroscopic structure was damaged. When over 80% dopaminergic neurons were lossed , contralateral rotations surpassed 7 r?min~(1) and c-fos expressed in the ipsilateral striatum. Conclusion APO induces c-fos expression in the ipsilateral striatum. Intrinsic relations may exist between dopaminergic neurons deletion and c-fos expression

Objective To investigate the relationship between molecular biological markers and recombinant human endostatin targeted therapy in non-small-cell lung cancer(NSCLC).Methods 68 cases patients with non-small-cell lung cancer to meet the requirements were randomly divided into group A (n=34)and group B (n=34).Group A received docetaxel and cisplatin(DP)and gefitinib;group B received recombinant human endostatin on the base of group A.The biological markers species,such as,EGFR,KRAS,VEGF,BRCA1,EML4-ALK,ERCC1,β-tubulin and CD3 were detected by immunohistochemical.The types of population for different programs were summarized according to the expression of biological markers and progression free survival (PFS)of the two groups. Results Group B median PFS was significantly longer than that in group A;no matter low or high expression of VEGF and BRCA1,group B median PFS was significantly longer than that in group A(P<0.05);high expression of ERCC1,KRAS,EML4-ALK andβ-tubulin,group B median PFS was significantly longer than that in group A(P<0.05);low expression of EGFR and CD3,group B median PFS was significantly longer than that in group A (P<0.05 ).Conclusion No matter low or high expression of VEGF and BRCA1 ,low expression of KRAS, ERCC1,EML4-ALK and β-tubulin and high expression of EGFR and CD3 in patients with non-small cell lung cancer may be more sensitive to the treatment of DP and gefitinib combined with recombinant human endostatin.

Objective To study the compressive education on nursing students in operation room.Methods 84 nursing students in practice were randomly divided into the observation group and the control group with 42 students in each group.The two groups were in a month to complete the teaching syllabus internship period.The control group received conventional teaching,on the basis of conventional teaching,the observation group was given compressive education.After the end of internship,nursing skill score,comprehensive quality,operation doctors'satisfaction degree were compared between two groups.Results After the compressive education,the nursing skill score,comprehensive quality,operation doctors'satisfaction degree in the observation group were significantly higher than those of the control group.Conclusions According to the source of pressure in the operation room,compressive education should be given to the nursing students and make them complete the practice in a relaxed and delight state.This can also reflect the humanistic care in teaching,which is worthy of being popularized in teaching in operation room.

Objective To investigate the impacts of mecobalamin on plasma inflammatory factors (plasma high-sensitivity C-reactive protein (Hs-CRP) and carotid artery plaques in patients with H type hypertension.Methods Forty-eight acute ischemic stroke patients who were diagnosed with H type hypertension in the People's Hospital of Taixing were collected,and they were randomly divided them into treatment group and control group,and 24 cases of each group.Patients in both groups were given conventional therapies,including treatment of anti platelet aggregation,plaque stability and reduced plaque treatment.While patients in the treatment group were given additional oral drug of mecobalamin,500 μg each time,three times a day,6 months in all.Each case was evaluated at the second day of hospitalization,four weeks later,eight weeks later,three months and sixth months later.The examination items involved included level of plasma homocysteine(Hcy),level of hsCRP and conditions of carotid artery plaques under ultrasonography.Results Aafter four weeks,eight weeks,three months and sixth months therapy,there were significant differences between treatment group and control group in terms of Hcy (t =4.049,3.896,6.052,6.159 ; P ＜ 0.05) and the level of hs-CRP (t =37.249,28.376,26.454,0.522P ＜ 0.01).Afrter three months and sixth months therapy,compared to the control group,the carotid artery plaques were obviously reduced,and the differences were statistically significant (t =2.309,2.434 ; P ＜ 0.05).Conclusion Mecobalamin can reduce the level of plasma homocysteine,then lead to reductions of levels of plasma inflammatory factors and volume of carotid artery plaques.

Objective To explore the relationship between the expression of thrombospondin-2 (TSP-2), the changes of MVD and angiogenesis in non-small cell lung cancer (NSCLC). Methods By using SP immunohistochemical staining, the expression of TSP-2 and microvessel counting were evaluated in surgically resected specimens from 55 patients with NSCLC and 30 patients' pancancerous tissues, using the anti-TSP-2 and anti-CD34 monoclonal antibodies respectively. Results Active angiogenesis took place in NSCLC tumor tissues. Microvessel density (MVD) was associated with metastasis and clinical stage of NSCLC. Expression level of TSP-2 in the tumor tissues of 55 NSCLC patients was significantly higher than that in the pancancerous tissues from other 30 patients (149.10?2.94 vs. 145.70?4.74, P

Objective To evaluate the impact of hepatitis B e antigen (HBeAg) states and hepatitis B virus DNA loads on the prognosis of chronic severe hepatitis B.Methods A total of 406 hospitalized patients with chronic severe hepatitis B in Nanfang Hospital of Southern Medical University from January 2002 to December 2007 were retrospectively analyzed.The impact of HBeAg states and HBV DNA loads on the prognosis was evaluated.The measurement data were compared by t test and rates were compared by chi square test.Results Of all the 406 patients with chronic severe hepatitis B,208 (51.2%) patients were HBeAg-positive and the remaining 198 (48.8%) were HBeAgnegative.There was no significant difference of constituent ratio of male and female,average peak value of total bilirubin and average valley value of prothrombin activity between HBeAg-positive group and HBeAgnegative group.However,the average age of HBeAg-negative patients was (46.7±12.8) years old,which was significantly higher than that (38.3±13.5) years old in HBeAg-positive group (t = 6.43,P＜0.01 )the proportion of patients with liver cirrhosis in HBeAg-negative group (67.7%) was much higher than that in HBeAg-positive group (45.7%) (X2=19.97,P＜0.01);the improved rate in HBeAg-negative group (32.3%) was significant lower than that in HBcAg-positive group (44.7%) (X2=6.56,P＜0.05).Increasing HBV DNA levels was associated with lower improved rate in both 208 HBeAg-positive and 198 HBeAg-negative patients(X2=22.98,26.04,respectively,both P＜0.01 ).Conclusions HBeAg-negative patients with chronic severe hepatitis B has worse prognosis than HBeAg-positive patients;and the prognosis is getting worse with the increasing HBV DNA level regardless of the HBeAg status.

Objective To investigate the interrelation between nuclear DNA content and the expressions of cyclin D1 and P53 in carcinogenesis of breast carcinoma induced by 7,12 dimethylbenz(a)anthracence(DMBA) in rats. Methods Animal model of breast carcinoma was replicated by gastric perfusion of DMBA at 20 mg/100 g. Nuclear DNA content was detected with image analysis instrument and the expressions of cyclin D1 and P53 at every stage of carcinogenesis of breast carcinoma induced by DMBA in rats observed by Sp immunohistochemical staining. Results In mammary gland tissue at grade Ⅰ, grade Ⅱ and grade Ⅲ atypical hyperplasia of breast carcinoma, there was overepression of cyclin D1(3/20, 6/20 and 11/20, respectively). The overexpression of cyclin D1 was detected to be present in grade Ⅰ, grade Ⅱ and grade Ⅲ breast carcinoma (7/9, 1/4 and 0/7, respectively). The overexpression of P53 was detected to be present in grade Ⅰ, grade Ⅱ and grade Ⅲ breast carcinoma (1/9, 1/4 and 6/7, respectively). Conclusion Nuclear DNA content reflects the state of cell proliferation. Cyclin D1 overexpression participates in the carcinogenesis of breast carcinoma, which may be the early event in breast carcinoma. P53 expression is associated with the development of breast carcinoma, which may be the late event in breast carcinoma. The expression of cyclin D1 is negatively correlated with P53 overexpression.

Objective:To evaluate the effectiveness and safety of butyl phthalide capsules combined with Xueshuantong injection in the treatment of acute cerebral infarction (ACI). Methods: Cochrane Library, Medline, Embase, SCI, CBM, CNKI, VIP and Wanfang databases were searched from the building time to May 2016. The enrolled randomized controlled trails were studied by using Cochrane system evaluation methods to perform methodological quality assessment, and RevMan 5. 2 software was used to carry out Me-ta-analysis. Results:A total of 7 randomized controlled trails including 640 patients were enrolled. The results of Meta-analysis dem-onstrated that the effective rate of butylphthalide capsules combined with Xueshuantong injection was superior to that of Xueshuantong injection (RR=1. 33, 95%CI:1. 16-1. 52, P<0. 0001), butylphthalide (RR=1. 45, 95%CI:1. 15-1. 83, P=0. 002) and blank control (RR=1. 31, 95%CI:1. 08-1. 57, P=0. 005). NHISS of butylphthalide capsules combined with Xueshuantong injection was higher than that of Xueshuantong injection (MD=4. 63, 95%CI:3. 38-5. 87, P<0. 00001) and blank control (MD=6. 85, 95%CI:4. 90-8. 80, P<0. 00001). There was no significant difference in adverse drug reactions. Conclusion: Butylphthalide capsules combined with Xueshuantong injection is effective for the therapy of ACI. However, due to the limited quantity and quality of the in-cluded studies, larger scale trials are needed.

Objective To discuss the methods of the heat preservation performance monitoring of the blood transport case and to provide the technical support for the safety of blood transportation.Methods At the different environment temperature,the amount of the cold resource was decided by the mass ratio of cold resource to blood and the temperature was automatically recorded by the intelligent temperature chip continuously,to monitor the changes of each monitoring point in the blood transport case.Results When the mass ratio of cold resource to blood was fixed at 1∶6,the cold chain of the blood transport case could keep the tempera-ture of 2-10 ℃ for 8 hours at the environment temperature of 12 ℃,It could keep the temperature of 2-10 ℃ for 4.5 hours at the environment temperature of 25 ℃,and it could keep the temperature of 2-10 ℃ for 2 hours at the environment temperature of 44℃.Conclusion When the mass ratio of cold resource to blood is fixed,as the environment temperature changes,the available time that the blood transport case keeps with the cold-chain requirement varies according to the results of the heat preservation per-formance monitoring of the blood transport case.

Objective: To observe the effect of amlodipine on bone marrow endothelial progenitor cell (EPC) mobilization, neo-vascularization and cardiac function in diabetic rats after myocardial infarction (MI) with the possible mechanisms.
Methods: A total of 60 male SD rats were divided into 2 groups. Normal group, n=20. Diabetic group, n=40, the rats were fed with high fat diet (HFD) for 4 weeks and then received streptozotocin followed by left anterior descending coronary artery ligation to establish MI model, those rats were further divided into 2 sub-groups:Control group, the rats received sodium carboxymethylcellulose 1 ml/day with HFD and Treatment group, the rats received amlodipine 2 mg/kg/day with HFD, n=20 in each sub-group, all animals were treated for 4 weeks. The EPC level in peripheral blood CD45-/low+/CD133+/KDR+ at before and 1, 3, 5, 7, 14, 28 days after operation were examined by lfow cytometry, plasma vascular endothelial growth factor (VEGF) level was measured by ELISA, capillary density in MI area was determined by CD31 staining, EPC related protein expressions were detected by western blot analysis and the cardiac function was evaluated by echocardiography.
Results: EPC in CD45-/low+/CD133+/KDR+in Treatment group at 7 days after operation was increased than Control group at 5 days after operation (112 ± 30/106) vs (55 ± 10/106), plasma VEGF in Treatment group was higher than Control group (5.63 ± 1.33) ng/L vs (3.68 ± 0.98) ng/L; Treatment group presented increased expressions of protein kinase B, endothelial nitric oxide synthase (eNOS) and matrix metallopeptidase-9, increased capillary density in MI area, higher LVEF and left ventricular fractional shorting, all P<0.05-0.01.
Conclusion: Amlodipine improves EPC mobilization, neo-vascularization and cardiac function in diabetic-MI rats, it may be related to VEGF/eNOS cascade activation.
