Our experiments have shown that bee venom possesses effects of significantly increasing the fluidity of erythrocyte membrane,markedly decreasing the whole blood and plasma viscosities,accelerating erythrocyte microelectrophoresis speed and reducing erythrocyte rigidity index in rabbit. The results showed that bee venom can markedly change some of the parameters of hemorrheology,and possess certain effects in promoting blood circulation to remove blood stasis.

Objective To explore the conventional MRI,diffusion-weighted imaging (DWI)characteristics and the pathological basis of angiomatous meningioma.Methods The conventional MRI,DWI and pathological manifestations of 7 cases with angioma-tous meningioma confirmed by surgery and pathology were analyzed retrospectively.The apparent diffusion coefficient (ADC)value of the tumors and contralateral normal brain parenchyma were measured and compared with each other.Results Among the 7 ca-ses,5 cases were in the convexity of brain (4 cases in the frontal part and 1 case in the parietal part),and 2 cases in the parasella. 6 cases showed hypointense on T1 WI and hyperintense on T2 WI,and 1 case showed isointense on both T1 WI and T2 WI.The necro-sis within the tumor was seen in 2 cases.The flowing void phenomenon was seen in 6 cases.The significant peritumoral edema was seen in 5 cases on FLAIR.Significant enhancement on contrast-enhanced T1 WI was seen in all the cases.The average ADC value of the tumors (1.35×10 -3 mm2/s)was significently higher than that of the contralateral normal parenchyma (0.92 × 10 -3 mm2/s) (t=7.21,P <0.01).Mature vessel component was seen on pathological section in all the cases.For immunohistochemically analy-sis,the expression of vimentin (Vim)was positive in 6 cases and scattered positive in 1 case.The expression of epithelial membrane antigen (EMA)was positive in all the cases.Conclusion The MRI features of angiomatous meningioma are closely correlated with rich blood vessels.The ADC value of the tumor is higher than that of the contralateral parenchyma,which is helpful for the diagno-sis.

Doctor-patient relationship is a special relationship between people in special circumstances during a special peri -od, which is directly related to the harmony and stability of society as well as people's quality of life.Values are the fundamental views of people, including the understanding of the nature , composition and standards of values .Doctors and patients are consistent in goals , interests and ideals , having the same objectives to overcome diseases , promote health , and prolong lives .They are essentially unified in values.However, there are some inharmonious phenomena in the relationship between doctors and patients .Efforts should be made to improve the present doctor-patient relationship by the whole society besides doctors and patients , aiming to establish a harmonious doctor-patient relationship of mutual respect , mutual trust , mutual tolerance and mutual cooperation on the basis of common values .

Multiple risk factors lead to occurrence of cardiovascular diseases in common.Besides confirmed tradition-al risk factors,such as diabetes mellitus,dyslipidemia,smoking and hypertension etc.,some new risk factors have been found in recent years.The confirmed risk factors need further research,while the new risk factors need en-hanced study.

At present,the commonly used tumor markers,with low sensitivity and low specificity,can 't achieve the purpose of early diagnosis.However,autoantibodies against tumox-associated antigens have been detected in the asymptomatic stage of cancer and thus can serve as biomarkers for early cancer diagnosis.Moreover,due to autoantibodies are found in sera,they can he screened easily using a noninvasive approach.The discovery of panels of autoantibodies with high sensitivity and specificity will help to improve the diagnostic and prognostic for the patients with cancer.

To explore the allocation and equity of health resource in Changsha between 2007 and 2013 and to provide references for government to carry out regional health planning. Method:General statistical analysis was used to describe changes of health resource allocation in Changsha;from the perspective of the population and geography of the nine counties in Changsha, the equality and change of the configuration among doctors, nurses and hospital beds were analyzed by using the Gini coefficient and Theil index. Results:1) The per capita amount of health resources in Changsha increased gradually, and health resources were mainly concentrated in urban areas. 2 ) The Gini coeffi-cients of doctors, nurses and hospital beds was 0. 24~0. 46 according to population distribution between 2007 and 2013 in Changsha, and the Gini coefficient of all health resources by geography was 0. 59~ 0. 79 and peaked in 2009 to then decrease year after year. Following a comparison of the two kinds of regions, the Gini coefficient of urban are-as was significantly higher than that of rural areas, and the Gini coefficient of nurses was the highest among all health resources. 3) Changes in the Theil index were consistent with the Gini coefficient. The difference in the degree of re-source allocation in urban areas exhibited a rising trend, The Theil index was higher than each regional difference. Conclusion:Overall, the equity of allocation of health resources in Changsha between 2007 and 2013 gradually im-proved year by year. The equity of population configuration was greater than that of geographical configuration, and the equity of rural areas was superior to that of urban areas;the equity of the configuration of nurses was poor. The difference between areas is the main factor affecting the equity of Changsha’s health resource allocation.

BACKGROUND:Spinal canal decompression and fusion combined with pedicle screw fixation has become the main method for the treatment of thoracolumbar fracture and dislocation. OBJECTIVE:To restore the vertebral height of the patients with thoracolumbar fracture and dislocation who underwent subtotal resection and decompression through titanium cage packed with autologous cancel ous bone and pedicle screw fixation. METHODS:Thirty-one patients with thoracolumbar fracture and dislocation treated in the Shanghai 6th People’ s Hospital of Shanghai Jiao Tong University from February 2007 to September 2011 were selected. Al the patients received subtotal resection, spinal canal decompression and titanium cage packed with autologous cancel ous bone and pedicle screw fixation. Imaging examination was performed before and after treatment to observe the recovery of vertebral sequence, vertebral height and Cobb angle, as wel as the recovery of nerve function. RESUTLS AND CONCLUSION:The patients were fol owed-up for 12 months, and al the patients healed wel after treated with titanium cage packed with autologous cancel ous bone and pedicle screw fixation, and there was no loosening, shedding or breakage after pedicle screw fixation. During reexamination, the grafts fusion, good deformity correction, basic recovery of vertebral height and good recovery of Cobb angle were observed. Seven cases had neurological function recovery, and among them, six cases raised for one degree, one case raised for two degrees, and another 22 cases without recovery. Case analysis and relative researches showed that subtotal resection and decompression and titanium cage packed with autologous cancel ous bone and pedicle screw fixation can reduce the loss of correction of the patients with thoracolumbar fracture and dislocation, restore the vertebral height, and enhance the stability of the vertebral body.

Objective To investigate the clinicopathologic and immunohistochemical features of gastric stromal tumors.Methods A total of 105 cases with gastric stromal tumors were included in the study.The expression of cluster of differentiation 117 (CD117),cluster of differ entiation 34 (CD34),smooth muscle actin (SMA),S-100 protein and Ki-67 in gastric stromal tumors specimens was detected by immunohistochemistry.The clinico-pathologic features of gastric stromal tumors were also analyzed.Results Of 105 gastric stromal tumors specimens,90 were positive for CD117 [85.7 ％ (90/105)],98 positive for CD34 [93.3 ％ (98/105)],21 positive for SMA [20.4 ％ (21/105)],60 positive for Ki-67 [56.1％ (60/105)],13 positive for S-100 [12.4 ％ (13/105)].Conclusion Combined detection of CD117 and CD34 can improve the diagnostic accuracy of gastric stromal tumors.The expression of Ki-67 can be used as a prognostic parameter for gastric stromal tumors as it is correlated with tumor size,risk and mitotic.

The number of IPFI has increased in recent years because of the increasing of immunocompromised hosts due to abuse of antibiotics,glucocorticoids,immunosuppressants and all kinds of invasive operations,organ transplants.The mortality of IPFI remains highly because it's difficult to early diagnosis.Histopathologic biopsy remains as the gold standard for IPFI diagnosis although limited by materials.Imaging manifestations are nonspecific but have important suggestive values to some kinds of fungus.Direct examination is quickly but it's difficult to distinguish strain.Fungal culture can guide the treatment but its positive rate is low and the distinguish for contamination,infection and colonization is hard.Serological test has high sensitivity and specificity,but it cannot distinguish strain and it can yield false positives and false negative.Molecular biology is one of rapid developing methods,but its application is limited due to lack of standardized procedures and standards to assess its results,furthermore it can yield false positives.The proper diagnosis for IPFI relies on the comprehensive assessment combing with advantages and disadvantages of various methods.
