Objective To evaluate the performance of T-SPOT.TB Test and serological tuberculosis antibody(TB-Ab) in tuberculosis-assisted diagnosis.Methods Patients were diagnosed as tuberculosis from 2015 January to 2016 March in the hospital.T-SPOT.TB and tuberculosis antibody detection were performed for those patients.Results In 112 cases of tuberculosis patients,101 cases of T-SPOT.TB test were positive and the sensitivity was 90.18%,32 cases of tuberculosis antibody detection were positive and the sensitivity was 28.57%.In 41 cases of pulmonary tuberculosis,T-SPOT.TB assay showed positive results in 40 patients and the sensitivity was 97.56%,tuberculosis antibody detection showed positive results in 18 patients and the sensitivity was 43.9%;in 71 cases of extrapulmonary tuberculosis,T-SPOT.TB assay showed positive results in 61 patients and the sensitivity was 85.91%,tuberculosis antibody detection showed positive results in 14 patients and the sensitivity was 19.7%.Conclusion T-SPOT.TB was superior to serological tuberculosis antibody(TB-Ab),and the diagnosis of active tuberculosis was higher,and the sensitivity of T-SPOT.TB was higher than that of T-SPOT.TB value.

Objective To investigate the role of vascular endothelial growth factor-C (VEGF-C) and its receptors in the formation of lymphatic vessels and lymphatic metastasis in gastric cancer. Methods By the domestic and overseas literatures review,the expressions of VEGF-C and its receptors in gastric cancer,their role in tumor lymphatic metastasis and prospect in treatment of gastric cancer were summarized. Results There was a significant correlation between VEGF-C and its receptors and the formation of lymphatic vessels and lymphatic metastasis in gastric cancer. VEGF-C high expression might be an early event in lymphatic metastasis and could be considered as an independent predictive factor of lymphaticmicrometastasis. By inhibition of gastric cancer cell from secrete VEGF-C or blockage of the interaction of VEGF-C with VEGFR-3,it was possible to inhibit tumor angiogenesis and the invasion and distant spread of cancer cells,thereby decreased mortality and improve survival. Conclusion VEGF-C and its receptors may promote the formation of lymphatic vessels and lymphatic metastasis in gastric cancer. It may be an effective way to gastric cancer for the treatments against VEGF-C and its receptors.

Objective To explore the correlation of pathological changes and imaging through a control study on pathology and imaging of 4 cases of senile dementia of the Alzheimer type (SDAT).Methods By HE and Gallyas silver dyeing,four immunohistochemical methods were carried out The loss of neurons cells of all lobes of cerebral cortex,cingulate gyrus,amygdaloid nucleus,hippocampal gyrus,parahippocampal gyrus,meynert basal nucleus,substantia nigra,locus ceruleus,dorsal nucleus of vagus nerve,senile plaques (SP) and the changes of neurofibrillary tangles (NFT) were observed in detail The control study of pathology and imaging was carried out by comparison of CT in different phases before and after death of the patient.Results The degeneration of temporal lobe was marked: (1) The degeneration of middle frontal gyrus of cortex of frontal lobe was the most evident; (2) The degeneration of long gyrus was more evident than that of the short gyrus as the cortex of insular lobe was concerned; (3) The degeneration posterior part of cingulated gyrus was more evident than that of the anterior part.Conclusion The pathological findings of SDAT mentioned above are basically in conformity with the changes of imaging.

Objective To study the specific sequences in the 3'untranslated region (UTR) of the SON gene of human beings and 14 kinds of mammalian. Method The specific sequences in the 3'untranslated region (UTR) of the SON gene of human beings and 14 kinds of mammalians were amplified and directly se-quenced. The sequence data of PCR products of human beings and mammalians were declared. Results The sequences of 3'UTR of SON gene of human beings differed from 14 kinds of mammalians. The sequences of samples came from different human individuals did not show any difference. Conclusion The 3'UTR of SON gene is a good DNA region for specie identification. Using this technology, DNA of human beings can be distinguished from 14 kinds of mammalians. This technology is very useful in of forensic science.

Objective To retrospectively review the mortality and morbidity after orthopedic surgery for aged patients with reference to orthopedic version physiological and operative severity score for the enumeration of mortality and morbidity (O-POSSUM) and Portsmouth POSSUM (P-POSSUM) and validate the score' s accuracy in operative risk prediction.Methods O-POSSUM and P-POSSUM for mortality and morbidity were applied to 839 aged patients who had undergone orthopedic surgery between January 2008 and December 2011.Observed mortality and morbidity were compared with the expected values.Results O-POSSUM predicted 230 morbidities,but the observed value was 182 (x2 =2.718,P ＞ 0.05).O-POSSUM predicted 46 deaths,higher than the observed 3 deaths (x2 =38.870,P＜0.01).P-POSSUM predicted 16 deaths,higher than the observed 3 deaths (x2 =8.997,P ＜ 0.01).Conclusions O-POSSUM accurately predicts postoperative morbidity in aged orthopedic patients.However,O-POSSUM and P-POSSUM overpredicts the mortality and should be used with caution.

Objective To study the changes of the amplitude of ion channels currents in developing hippocampal neurons.Methods Using whole-cell patch-clamp techniques in cultured hippocampal neurons whose cultured day were 6 d and 16 d,respectively,changes of the amplitude of ion channels currents in developing hippocampal neurons were explored.Results Compared with the hippocampal neuron whose cultured day was 6 d,there were no statistical differences of the amplitude of voltage dependent sodium currents of hippocampal neuron whose cultured day was 16 d.The amplitude of voltage dependent potassium currents of hippocampal neuron whose cultured day was 16 d were significantly increased(P

Objective To study the changes of N-methyl-D-aspartate(NMDA)-receptor-channels current in developing hippocampal neurones during hypoxia and effect of adenosine intervention.Methods Whole-cell patch-clamp techniques cultured hippocampal neurons whose cultured day were 6 days and 16 days respectively,the amplitude of the NMDA-receptor-channels currents of hippocampal neuron were determined.And the effect of hypoxia on the NMDA-receptor-channels current,and adenosine regulatory mechanisms in cultured hippocampal neurons were explored.Results During hypoxia,compared with control group,the amplitude of the NMDA-receptorchannels currents of hippocampal neuron whose cultured day was 6 days were significantly increased(P
