Objective To observe the short-term curative effect and safety of recombinant human erythropoietin(rHu-EPO)on patients with primary brain stem injury. Methods Sixty patients with primary brain stem injury were recruited at Liaocheng People' Hospital from July 2010 to July 2013. All cases were randomly divided into EPO group and control group. The patients in EPO group were injected subcutaneous with rHu-EPO five times at dose of 6 000 U,while patients in the control group were treated with placebo in 2 weeks. All other conventional treatments were the same. NIHSS score and GOS score were evaluated in two weeks and three months respectively. Moreover,blood pressure and hemoglobin were also measured. Results NIHSS score in EPO group was 11. 37 ± 7. 78,significant higher than that of control group after two weeks(19. 41 ± 8. 26,P = 0. 019). GOS score in EPO group was also significant differences in two groups after three months (Z = - 2. 367,P = 0. 009 ). However,no significant difference was observed in the followed-up blood tests. Conclusion Recombinant human erythropoietin could be the exact nerve protective effect,and might be an effective therapy for patients with primary brain stem injury.

24.34, the sensitivity and specificity were 95.0% and 75.8%, respectively. Conclusion: The autofluorescence spectrum of dilute gastric juice may become an effective means in the diagnosis and screening of gastric carcinoma.

Objective:To evaluate the clinical correlation between the CardioChek PA analyzer (CCPA)and a clinical laboratory reference method to use for screening program purposes.Methods:Fasting blood samples were collected on 325 patients (age:23 -86 years).One venous sample was col-lected using a serum tube for the evaluation on a Beckman reference analyzer.A second venous sample was collected in a lithium heparin tube and was evaluated on the CCPA analyzer.Linear regression analy-ses and Bland-Altman method were performed for each measured analyte:total cholesterol (TC),high density lipoprotein-cholesterol (HDL-C),triglycerides (TG)and low density lipoprotein-cholesterol (LDL-C).Results:Our results demonstrated a good clinical agreement for TC,HDL-C,TG and LDL-C (97.0%,92.9%,92.4% and 83.7%)in comparison with the CCPA to the reference analyzer.The correlation coefficients were 0.875,0.81 3,0.91 0,0.864,respectively.P values all <0.001 .There was no significant difference in the detection rate of hyperlipidemia in TC,HDL-C and LDL-C.Conclu-sion:We have identified the pre-analytic phase as an important step to guarantee the quality of results and indicated that the CCPA is a reliable lipid point-of-care testing system that can be used for the appli-cation of clinical screening anywhere.

To investigate the protective effect of the seed oil of Abelmoschus esculentus on gastric ulcer,two acute gastric ulcer mice models were established by intragastric administration of aspirin or absolute ethanol,respectively.Clinical index of ulcer area,ulcer index,gastric volume,gastric pH value,free acidity,total acidity,and histopathological assessment were measured to evaluate the injuries of gastric ulcer and the protective effect of okra seed oil In order to comprehensively uncover the possible underlying mechanism,a series of biochemical assays were also performed,including serum TNF-α,IL-6,IL-10 and Tbil,NO,MPO and SOD in the stomach included.Moreover,the ALT,AST and ALP in the liver of mice were also tested to evaluate the possible hepatic toxicity of the seed oil.The results indicated that the seed oil of A.esculentus exerted protective effect in ethanol-induced gastric ulcer mice by reducing the ulcer area and ulcer index,declining the free and total acidity,and increasing the pH value of gastric content.Histopathological observation showed the gastric mucosa of the acute gastric ulcer mice induced by alcohol was incomplete and severely damaged,with submucosal edema and nuclear pyknosis,as well as glandular structure disappearing,compared with that of normal mice.What's more,a number of inflammatory cell infiltration occured in the gastric mucosa of alcohol-model mice,with messes of neutrophils,lymphocytes,eosinophils and plasma cells.Okra seed oil could improve the damaged structure of the gastric mucosa and gland caused by ethanol,but could not ameliorate the condensation of nucleus and infiltration of inflammatory cells.Biochemical analysis revealed that the seed oil of A.esculentus could counteract the damage induced by ethanol via decreasing Tbil and TNF-α in serum,decreasing NO and myeloperoxidase,and increasing SOD in stomach.Meanwhile,okra seed oil exhibited protective effect in aspirin-induced gastric ulcer mice by increasing the gastric content pH,and reducing free and total acidity.Compared with the control group,the gastric mucosa of aspirin-model group showed multifocal coagulation necrosis,sheet edema and infiltration of inflammatory cells by histopathological assessment.Compared with the aspirin-model group,the soybean oil group and okra seed oil group could ameliorate the inflammatory cell infiltration.Biochemical analysis revealed that okra seed oil could counteract the injury induced by aspirin via decreasing TNF-α and IL-6,and increasing IL-1O in serum,decreasing NO and MPO and increasing SOD in stomach.In a word,the okra seed oil exerted protective effect on acute gastric ulcer by anti-inflammation,anti-oxidation and hepatocyte protection.The okra seed oil deserves further development and utilization.

Objective To investigate the recent efficacy and safety of autologous bone marrow stem cells transplantation in treatment of early spinal cord injury. Methods 51 cases of early spinal cord injury admitted to Liaocheng People Hospital from 2007.11 to 2009.8 were enrolled in this study. In transplantation group, 24 patients were treated by subarachnoid space injection with autologous bone marrow stem cell transplantation. The patients who were not transplanted in the same period of hospitalization were selected as control group. Motor and sensory function ( AISA score) was assessed at 1, 3, 6 months before and after transplantation in two groups patients. And blood routine, clotting mechanisms, biochemical items andtunor markers were determined in followed up. Results After one month of transplantation, two groups ofpatients had recovered in motor and sensory function to some degree. After three months of transplantation,there was significant different between transplantation group and control group in sensory function recovery (P < 0. 05 ). After 6 months of transplantation, there were significant different between transplant group and control group in motor and sensory function recovery (P<0.05). Blood examination results did not show markedly abnormal in followed -up patientsConclusion The safety and recent effect of autologous bone marrow stem cells transplantation in treatment of early spinal cord injury were satisfied, but the long - term effect was still unclear.

BACKGROUND: Previous animal studies demonstrated that bone marrow mesenchymal stem cells could differentiate into nerve cells under a certain condition; however, the clinical application for treating nervous system disease has been less reported. OBJECTIVE: To observe a short-term effect of autologous bone marrow mesenchymal stem cell transplantation on treating cerebral hemorrhage.METHODS: A total of 32 patients with cerebral hemorrhage who were selected from the Department of Neurosurgery, Liaocheng Brain Hospital between November 2007 and January 2009 were considered as a treatment group. According to general data and the amount of hematoma, they were treated by drilling drainage or hematoma evacuation. Drainage tubes were detained into hematoma cavity, and 3.5 mL autologous bone marrow mesenchymal stem cell suspension was injected through drainage tube. A total of 40 additional patients who did not treated with stem cell transplantation were considered as a control group. Neurologic impairment (NIHSS) and activities of daily living (Barthel index) were performed before and 6 months after transplantation; meanwhile, the brain MRI, serum biochemical and tumor marker were evaluated to detect security of stem cell transplantation. RESULTS AND CONCLUSION: The NIHSS score and Barthel index in the treatment group were similar to those in the control group before transplantation. Compared with control group, NIHSS scores were significantly decreased in the treatment group (P < 0.01), but Barthel index was significantly increased 6 months after transplantation (P < 0.01). Compared with before transplantation, NIHSS score were significantly decreased (P < 0.01), but Barthel index was significantly increased in the treatment group 6 months after transplantation (P < 0.01). Two patients in the treatment group had febrile, which was recovered after treatment. The following-up 6 months after transplantation demonstrated that brain MRI and biochemical indicators were normal except an increasing of CA-153 caused by lung cancer in one patient. The autologous bone marrow mesenchymal stem cell transplantation for treatment of cerebral hemorrhage is safe and effective in a short-term period; however the long-term effect still needs to be further studied.

Objective To explore the feasibility of the application of non fasting blood lipid in the hospitalized population.Methods Self-control study was used.608 patients(aged 20~86 years old) were enrolled from April 2015 to October 2016 in lipid center of FuWai hospital.Fasting sample and non-fasting sample(1~4 h after breakfast) were collected from every patient and lipid profile including TG (triglyceride), TC (total cholesterol), HDL-C (high density lipoprotein cholesterol) and LDL-C (low density lipoprotein cholesterol) were measured in clinical laboratory.The results of two tests were compared using the Wilcoxon signed-rank test.Results The differences between non-fasting and fasting lipid test were +0.47 mmol/l (+30%) for TG,-0.03 mmol/l (-2.8%) for HDL-C,-0.09 mmol/l (-3%) for LDL-C and-0.24 mmol/l (-8.7%) for calculated LDL-C (P<0.001 respectively).The differenceswere +0.01 mmol/l for TC and +0.02 mmol/l for non-HDL-C,therefore no statistical difference was observed.When the TG level was stratified,the level of non-fasting LDL-C using directing test method was not significantly different between TG> 4.5 mmol/L and the whole (0.07 vs.0.09),but the level of non-fasting LDL-C using formula method wassignificantly different between TG> 4.5 mmol/L and the whole (0.66 Vs.0.24),andthe drops were 34.9% vs.8.7%.Conclusion Non-fasting lipid test could be an effective routine method for lipid evaluation in the hospitalized population.
