Objective To study the relationship between the MRI features and pathological types of intracranial meningiomas. Methods MRI findings of intracranial meningiomas in 63 cases proved by operation and pathology were analyzed retrospectively.Results Of 63 cases,62 cases were singular and one case was multiple lesions. The lesions were located in frontal,parietal and occipital regions nearby the convexity of the brain in 30 cases,in sellar region in 10,at sphenoidal crest in 8 , at olfactory sulcus in 5 and at other regions in 10. Isointense or slightly hypointense signal on T 1WI was found in 87.27% cases of meningiomas . On T 2WI, tumors had isointense or slightly hyperintense signal in 69.84%, obviously hyperintense signal in 19.05%,heterogenous texture signal in 7.94% and slightly low intense signal in 3.17%. Pathological type was included meningiomas meningothelial(n=29), meningiomas fibrous(n=11) , meningiomas psammomatous(n=8),angioblastic meningiomas (n=5) and meningiomas angiomatous(n=10). Conclusion It is great value in diagnosis of meningiomas with MRI. Meningiomas angiomatous show effecting of blood-vessel flowed empty with MR imaging.

16 and the distribution of severe trauma more than 2 anatomic parts.They were randomly divided into two groups:intensive insulin treatment group(n=31)and control group(n=31).Intensive insulin treatment group received insulin with insulin pump in order to maintain blood glucose levels at 4.0-6.1 mol/L,while the control group received routine insulin treatment in order to mmaintain blood glucose levels at 10.0- 11.0 mol/L.Plasma levels of TNF-?,IL-1,IL-6, CRP,APACHEⅡscores and cure rate were analyzed before and after the treatment.Data was expressed as mean?standard deviation.Two- tailed T test and ANOVA were used for comparison in SPSS 10.0,and changes were considered as statistically significant if P value was less than 0.05.Results After the intensive insulin treatment, patient's hemodynamic parameter apparently improved,APACHEⅡscores descended,and the levels of TNF-?, Ib-1,IL-6,CRP all declined,in comparison with control group,there were significant differences. Intensive insulin treatment might improve patient's general condition and decrease complications and mortality of severe multiple trauma.

PURPOSETo investigate the potential correlation between two different types of hip fractures and serum calcium levels.

METHODSWe consecutively studied 101 cases of femoral neck fracture and 95 cases of femoral inter- trochanteric fracture between January 2011 and December 2013. Fasting blood samples were taken and serum calcium measurements were performed respectively in three periods: the time of admission, postoperation, and discharge. Creatinine, alkaline phosphatase and albumin were also analyzed.

RESULTSConsidering the levels of serum calcium between two groups at the time of admission, post- operation and discharge, there was significant difference at admission and discharge (p <0.05), while there was no significant difference at the time of postoperation (p > 0.05). The magnitude of serum calcium fluctuation was larger in femoral neck group than femoral intertrochanteric group. Concerning alkaline phosphatase and albumin levels at admission, there was no significant difference between two groups (p > 0.05).

CONCLUSIONThe capability of reservation and restoration of serum calcium in patients with femoral neck fracture is better than that in patients with femoral intertrochanteric fracture. A low serum calcium level may be susceptible to femoral intertrochanteric fracture.

Objective:To study the influences of Mycoplasma penumoniae capsular polysaccharide (CPS) on the phagocytosis and membrane molecules expression of the human peripheral blood mononuclear cells derived dendritic cells by binding to dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN),so as to know the effect of CPS on the maturation of dendritic cells.Methods:M.pneumoniae strain was cultivated and CPS was extracted.Human peripheral blood mononuclear cells were separated and induced to dendritic cells,then identified the cells by flow cytometry and observation under the microscope.CPS was used to treat dendritic cells or cells pretreated with DC-SIGN monoclonal antibody,and then FITC-dextran phagocytosis and surface markers CD83,HLA-DR,CD80 and CD86 were detected by flow cytometry.Results:The dendritic cells tended to form colony groups.The positive rate of CD11c molecule in the cultured dendritic cells was about 86.27％.After stimulated by CPS,the FITC-dextran fluorescence mean intake by dendritic cells were increased (P＜0.05),while the cell surface membrane molecules CD83,HLA-DR,CD80 and CD86 were decreased significantly when compared with the PBS treated control cells(P＜0.05).When blocked DC-SIGN with the monoclonal antibody,the FITC-dextran fluorescence mean and membrane molecules expression had no statistical difference with the control cells(P＞0.05).Conclusion:M.pneumoniae CPS can promote the phagocytic function of DC and inhibit the expression of CD83,HLA-DR,CD80 and CD86.

Objective To study the antiviral effect of Jin Qiao Tablets on influenza A H1N1 virus in vivo. Methods The mouse pneumonia model was established by nasal inhalation of 15 LD50 of influenza virus. After prophylactic or therapeutic medication for 5 d,mouse lung tissue was taken out and weighed. Viral load in lung tissue was measured by polymerse chain reaction(PCR),and the level of γ-interferon(γ-IFN)in rat serum and lung was detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA)for evaluating the effect of Jin Qiao Tablets on lung index, viral load and γ-IFN in rats. After prophylactic or therapeutic medication for 7 d,morbidity and mortality within 14 d of mice with pneumonia induced by nasal inhalation of 3 LD50 were observed to evaluate the action of Jin Qiao Tablets for protecting against death and prolonging life span. Results Jin Qiao Tablets markedly decreased the increased lung index,promoted the death-protection rate and life-prolongation rate, decreased viral load, raised the level of γ-IFN in mice (P < 0.05 or P < 0.01). Experimental results in vivo showed that Jin Qiao Tablets had better anti-influenza virus activity than Yinqiao Jiedu Tablets and Lianhua Qingwen Capsules, and the effect of Jin Qiao Tablets was equivalent to that of Tamiflu. The prophylactic effect of Jin Qiao Tablets was stronger than the therapeutic effect, but there was no significant difference between them. Conclusion Jin Qiao Tablets have obvious effect against influenza A H1N1 virus in vivo.

OBJECTIVE: To compare the eradication rate, adverse reactions and compliance of the two 14-day bismuth-containing quadruple therapies in Liaoning Province as the first-line Helicobacter pylori(HP) eradication programs. METHODS: We collected222 eligible HP-infected patients who were admitted to the First Affiliated Hospital of China Medical University from March 2017 to October 2018 and treated with either of the following two programs:(1) EBLA group: esomeprazole(20 mg, twice a day), bismuth(200 mg, twice a day), levofloxacin(200 mg, twice a day) and amoxicillin(1 g, twice a day), 111 cases in total;(2) EBCA group:esomeprazole(20 mg, twice a day), bismuth(200 mg, twice a day), clarithromycin(500 mg, twice a day) and amoxicillin(1 g, twice a day), 111 cases in total. The patients in both groups were given medicines for 14 days, and the 13 C breath test was performed after4 weeks of withdrawal. RESULTS: The eradication rate of EBLA group was 87.34%(95%CI 80.9%-93.9%), and that of EBCA group was 83.33%(95%CI 76%-90.7%).There was no significant difference between the two groups(P=0.413). The incidence of adverse reactions was 10.8% in EBLA group and 26.13% in EBCA group. The difference was statistically significant(P=0.003). The compliance of patients in EBLA group was 99.10%, and that of EBCA group was 98.20%. The difference was not statistically significant(P=0.561).CONCLUSION: Both EBLA program and EBCA program can achieve good eradication rate and compliance in Liaoning province. The incidence of adverse reactions in EBLA group is lower than that in EBCA group, which is the preferred first-line HP eradication program.

Aim To investigate the mechanism by which ginsenoside Rgl regulates autophagy anrl delays brain aging in mice through AMPK/mTOR signaling pathway.Methods C57BL/6J male mice were ran¬domly divided into four groups, namely brain aging model group ,control group, Rgl anti-aging group,auto¬phagy activator Rapamycin anti-aging group.After the modeling was completed, the test of each experimental index would be carried out on the next day.Morris wa¬ter maze experiment was used to detect the learning and memory ability of mice.Paraffin sections of the hippocampus were prepared, HE , Nissl and immunohis- tochemical staining were used to observe the morpholo¬gy of hippocampal neurons, the number of neurons and Nissl bodies was counted, and autophagy-related proteins p62 , ATG5 , ULK1 were detected.Brain tissue homogenates were prepared to detect the aetivity of brain tissue acetylcholinesterase ( AChE ).Western blot was userl to detect brain tissue autophagy-related proteins LC3II, P62, beclinl, P-AMPK/AMPK, P- mTOR/mTOR and apoptosis protein P53.Results Water maze test showed that Rgl and Hap significantly improved the learning and memory abilities of brain-ag¬ing mice.HE and Nissl staining showed that Rgl and Rap decreased necrotic cells and increased the number of Nissl bodies in the hippocampus of brain-aging mice.Immunohistochemistry staining showed that Rgl and Rap decreased the expression of neuronal autoph- agv protein P62 in hippocampus and increased the ex-pression of ATG5 and ULK1.Rgl and Rap decreased the activity of AhcE in brain-aging mice.Western blot showed that Rgl and Rap increased autophagy-related proteins LC3II, Beclinl , P-AMPK/AMPK, but de¬creased the expression of P-mTOR/mTOR, P62, P53.Conclusions Ginsenoside Rgl can effectively antago¬nize the aging effect of D-gal on mouse brain.The pos¬sible mechanism is related to the regulation of autoph- agv by Rgl through AMPK/mTOR signaling pathway.
