Objective To investigate the application of xingnaojing injections ( XNJI) in inpatients and further provide a reference for the rational drug use. Methods The retrospective investigation was carried out by reviewing 186 hospitalization records with XNJI from a certain hospital from January 2014 to June 2015. The usage, dosage, and indication of XNJI were analyzed. Results Unlabeled use of XNJI was found in the neurology department inpatients. 59. 7% inpatients were treated with overdosed XNJI, and 13. 4% were treated with a single drug dose of 40 mL. The inappropriate solvent selection accounted for 49. 5%. Compatibility of XNJI and western medicine injection accounted for 54. 8%. It was also found that XNJI was used together with potassium chloride in clinic (47. 8%). Conclusion There exist some irrational uses of XNJI in clinic, thus the use and management of traditional Chinese medicine injections should be standarized.

When seen from the practice and development of modern medicine,we are facing challenges from various ethical problems which arise from the progress of life support technique,industry and network technique and its application in medicine,life sciences and electronic sciences.Nowadays,the legislation of medical ethics and regulations have become a heated issue drawing the attention of doctors,pharmacists,laboratorians,nurses,medical information staff,religions personnel,philosophers,medical scientists,and lawyers.This thesis tries to analyses the main ethical problems in the use of medical information so as to justify potential eligible ethical norms in clinical practice,expecting to draw the attention of relevant staff and general public and the fulfillment of ethical norms in the medical practice.

Objective: To observe the influences of sleep deprivation and antioxidant agent α-lipoic acid on the expression of IRE1 in the cortex and hippocampus in rats. Methods: Rats were randomly divided into control groups and sleep deprivation group. The control groups included blank control group (n=10) and environmental control group (n=10). Sleep deprivation group included 120 rats, and rats were further divided into α-lipoic acid group (25 mg.kg-1.d-1) and sleep deprivation model group. The two were further divided into 6 groups according to the periods of sleep deprivation and sleep restoration (SD 1 d , SD 3 d, SD 5 d, SD 7 d, SD 7 d/RS 6 h, SD 7 d/RS 12 h[n=10]). The expression of IRE1 mRNA and protein was examined by RT-PCR and immunohistochemistry, respectively. Results: RT-PCR results showed that the expression of IRE1 mRNA in the cortex and hippocampus were significantly higher in sleep deprivation group than in the blank and environmental control groups (P<0.05); there was no significant difference between the latter 2 groups. α-lipoic acid decreased the expression of IRE1. Expression of IRE1 between α-lipoic acid groups and sleep deprivation model groups was significantly different on SD 5 d, SD 7 d, SD 7 d/RS 6 h and SD 7 d/RS 12 h(P<0.05). The imrnunohistochemistry results of IRE1 expression were consistant with RT-PCR results. Conclusion: α-lipoic acid can reduce the cerebral IRE1 expression in sleep deprivation rats, which provides a basis for antioxidant treatment of sleep deprivation.

Objective To explore the best sampling position of bone marrow biopsy in mice.Methods Mice were sacrificed by cervical dislocation, then take the skull, sternum, tibial, femoral and iliac bone, making pathological section.Observed and photographed under light microscope. Comparison of the distribution of the essence and the hematopoietic microenvironment in different parts.Select site which can best reflect the hematopoietic function of bone marrow.Results A large number of hematopoietic cells in ilium marrow sections visible.The cells are evenly distributed. Blood and megakaryocytes were clearly visible.The arrangement of the structure of the scaffolds for tissue closely.The number of fat cells less.Bone marrow hematopoietic cells in the skull, sternum, tibial, femoral were not clear and not active.And there are more fat cells.Conclusions As the best sampling position of bone marrow biopsy, is ilium.

Objective To observe the protective effect of Danggui Buxue Decoction on 60 Co-γray irradiated mice. Methods The experimental mice were randomly divided into 5 groups ( the normal control group , model group , Danggui Buxue Decoction of low , middle and high dose groups ) .The mouse except the normal control group were irradiated by 60Co-γray and established the radiation-damage model.Peripheral blood neutrophil count (NEUT), the number of bone marrow nucleated cells ( BMC ) , the activity of serum superoxide dismutase ( SOD ) and the serum levels of malondialdehyde ( MDA) were measured .Results Radiation injury in mice of NEUT , BMC and SOD were significantly decreased (P <0.01), MDA were increased (P <0.01).Danggui Buxue Decoction can increase the levels of NEUT , BMC and SOD in mice after radiation injury , decrease the content of MDA .And protective effect of high dose group was better (P <0.01).Conclusions Danggui Buxue Decoction has protective effect on radiation injury in mice .And there is a correlation between the protection effect and dose .

Livedoid vasculitis is a kind of skin disease caused by local vascular occlusion.It mainly manifests as erythematous and purpuric maculas or papules on the legs and ankles,which may progress into intensely painful ulcers and heal leaving porcelain-white atrophic scars called atrophie blanche.Histopathologically,inflammatory response is weak or absent in local lesions of livedoid vasculitis,hence,it is commonly considered to be related to local thrombosis and other autoimmune diseases.Now,it is mainly managed with anticoagulation-based comprehensive treatment in clinic.

Objective To design and establish a set of diffusion optical tomography(DOT) system.Methods Near-infrared(NIR) laser was employed as the light source and only one photomultiplier tube(PMT) as the detector.An optical multiplexer was used to alter the detector channels.The 32 channels of the system,which are consisted of 16 launch channels and 16 detector channels,worked under the continuous-wave(CW) model and were used to acquire 256 boundary data.Results Experiments were performed based on the proposed imaging system.The intralipid was used as the tissue-like medium and the India ink as the absorber.Two sets of data on the boundary were sampled,respectively,before and after the absorber was embedded inside the tissue-like medium.The two sets of data were normalized and then used to reconstruct the absorption coefficient distribution.The recovered image reflected the real location and size of the absorber.Conclusion The proposed imaging platform can image the tissue optical parameters effectively.However the resolution of the reconstructed image was not high because the inverse problem was gravely underdetermined and the noise was not considered in the reconstruction algorithm.The recovered result in the next generation system could be improved by making more use of prior information and enhancing the performance of the system.
