To observe the changes in content of monoamine neurotransmitters in the serum of rhesus macaques, and explore the role of serum monoamine neurotransmitters in premenstrual syndrome (PMS) and liver-qi depression induced by anger-in emotion.

Objective:To analyse the imaging featrues of intractranial tuberculoma and improve the diagnostic accuracy.Methods:31 patients with clinical characteritics and pathological proved intracranial tuberculomas were studied retrospectively.Results:"egg-shell"calcification were the feature of giant calcified and ossified tuberculoma.CT scaning were single and multiple nodular lesion.In the contrast enhancing CT scaning,plate shaped or ring form shadows were shown.MRI were provided hypointense on T1WI and hyperintense on T2WI.The rim homogeneous enhancement were showd in the Gd-DTPA.Conclusion:The diagnosis of typical intracranial tuberculomas can be made.After antituberculosis chemotherapy,CT and MRI can help made differsntial diagnosis.Operative indications should be select strictly.

Objective To study CT and MRI features of intracranial chondrosarcomas. Methods CT and MRI of 3 cases with intracranial chondros arcomas proved by pathology were retrospectively analyzed.Results CT scans showed the tumors were lobular mass, per itumoral edema were not serious, intratumorous calcification and bone invasion w ere seen in 2 cases.MRI showed that tumor had low to intermediate signal intensi ty or hypointensity on T 1WI, high signal intensity on T 2WI. On contrast enha nced MRI,the center of lesions which was low signal intensity on T 2WI was no e nhancement, but there was observable enhancement at periphery of tumors.Conclusion Intracranical chondrosarcomas are often orgina ted from synchondrosis of the skull base,the lesions are often associated with c alcification, and bone invasion, the accurate dignosis should depend on microsco pic examination and immunohistochemical staining.

Objectives:To learn about the attitudes toward the "Global Minimum Essential Requirements(GMER) in medical education" between Chinese doctors and graduates from the same medical university and to offer reference for spreading GMER in China.Methods: To investigate the subbjects using a questionnaire describing the related abilities of GMER.Description,rank test,multivariate analysis of variance and factor analysis are applied in data analysis.Results: In general,there are different attitudes toward GMER between doctors and graduates.13 of 23 items have statistical significance in scores between groups.The proportion of person considering every item as important or very important among doctors is higher than that among graduates.There is statistical significance between groups on the transformed score in 7 domains of GMER.The domain of topmost score is "clinical skills",and of the lowermost one is "community health & health system".Conclusions: Doctors and graduates both accept GMER.They both pay attention to occupational skills,but ignore the public health.Doctors think much of basic knowledge,while graduates are short of the cognition on "Information Management".

Objective To explore the curative effect of combination therapy of low-temperature plasma radiofrequency ablation and nasal endoscopy for chronic nasal sinusitis. Methods From January 2010 to January 2012,98 patients with chronic nasal sinusitis in our hospital were ramdomly divided into observation group and control group. The observation group (49 cases) received plasma radiofrequency ablation at low temperature combined nasal endoscopic treatment. The control group (49 cases) were performed only nasal endoscopic treatment. The curative effect of the 2 groups were compared. Results After 1 month and 1 year, the total effective rate of the observation group were 91. 84% and 89. 80%, the total effective rate of the control group were 77. 55% and 73. 47% respectively. To compare the total effective rate of 2 groups were compared,there were statistically significant differences(P<0. 05). Conclusion Curative effect of plasma radiofrequency ablation at low temperature and nasal endoscopy is distinct,it is worthy of being widely applied in clinic.

Objective To investigate the effect of transplantation of allogeneic bone marrow hematopoietic cells(HCs)and mesenchymal stem cells(MSCs)on experimental colitis(EC)in rats.Methods The HCs and MSCs obtained from SD male rats were cultured and expanded in vitro.In experiment 1 and 2 groups,HCs were labeled with bromodeoxyuridine(BrdU)and MSCs were obtained using the tube wall attach technique,respectively.Seventy-two female rats were infused with trinitrobenzene sulfonic acid(TNBS)to induce EC models.After 24 hours,HC or MSC suspensions were injected into the rats in experimental 1(n=18)and 2(n=18)groups via caudal veins,respectively.Control animals were injected with isotonic saline.The whole colon was removed on day 7,14 and 21 after transplantation and examined histopathologically.BrdU labeled HCs were tested with immunohistochemical staining and MSCs were detected for sex-determining gene(sry)by PCR.Results EC models were successfully established.The HCs or MSCs grew rapidly in the culture suspension.On day 7,14 and 21 after transplantation,the BrdU immunoreactive cells were detected in the colon(6/6),and the positive expression of the sry gene was found in 1/6,2/6 and 3/6,respectively.No positive labeled cell was found in controls.There was no significant improvement in histopathological scores on the colon in two experimental groups compared with the controls.Conclusions Allogeneic HCs and MSCs may localize in the colon of EC models.The ability of localization is higher in HCs than MSCs.The transplantation of HCs and MSCs can not obviously improve histopathologically.

Objective To investigate the risk factors and treatment efficiency for lung cancer patients with venous thromboembolism (VTE). Methods Total 282 cases of lung cancer patients with VTE were enrolled into two groups , including the VTE group and the non-VTE group , for comparation analysis based on a series of clinical data. Results The occupation rate of adenocarcinoma and Ⅳ period were 65.28% and 87.50% in VTE group, respectively, higher than those of 51.43% and 75.71% in the non-VTE group. The increased rate of blood viscosity and d-dimer respectively were 65.28% and 70.83%, higher than those of 51.43% and 56.67% in the non-VTE group, with significant differences (P < 0.05, respectively). Result of logistic regression analysis showed that tumor stage , d-dimer levels , smoking , age , and blood viscosity levels were highly correlated with venous thrombosis in patients with lung cancer, and the OR value among them was 3.802, 2.339, 5.814, 3.875 and 6.404, respectively, with significant differencees (P < 0.05, respectively). Conclusions Lung adenocarcinoma with stage Ⅳ, smoking , age and increase of blood viscosity and d-dimer were the important risk factors for VTE in patients with lung cancer chemotherapy. Timely assessment of risk factors and early anticoagulation therapy in lung cancer patients with venous thromboembolism associated with VTE can improve the treatment efficacy and reduce the complications.

OBJECTIVE: The aim of this study is to investigate the expression and clinical significance of 6-phosphofructo-1-kinase in nasopharyngeal carcinoma biopsy samples. METHOD: Sixty-one biopsy samples were detected, including 41 tissues samples from patients with nasopharyngeal carcinoma and 20 tissues samples from patients with chronic nasopharyngitis as control group. 6-phosphofructo 1 kinase mRNA expression was detected by RTPCR. RESULT: It was observed that the expression levels of 6 phosphofructo-1-kinase mRNA in nasopharyngeal carcinoma tissues were higher than in the chronic inflammatory tissues. And the expression levels in patients with lymph node metastasis were higher than without lymph nod metastasis. CONCLUSION 6-phosphofructo-1-kinase may be a marker in occurrence and metastasis of nasopharyngeal carcinoma.

The cDNA fragment of JEV prME gene was cloned into the baculovirus shuttle vector (bacmid) to construct a recombinant baculovirus vector, defined as AcBac-prME. Then the recombinant baculovirus Ac-prME was obtained by transfecting Sf9 cells with AcBac-prME. Western blot analysis and immunofluorescence results indicated that both prM and E proteins were efficiently expressed in Sf9 cells. Electron microscopy suggested that prME was assembled into JEV-VLPs. To further evaluate the potential of JEV-VLPs as vaccine, the mice were immunized with JEV-VLPs and then challenged with lethal JEV. The results of mice survival and pathological changes demonstrated that the JEV-VLPs performed complete protection against JEV-P3 strain and relieved pathological changes in the mice brain significant. This study suggest that JEV-VLPs would be a potential vaccine for Japanese encephalitis virus.
