Objective: To analyze the problems of large medical equipment allocation in our country, put forward the method and basis of scientific configuration. Methods: The current situation of large medical equipment allocation was analyzed by the methods of literature, statistics and analysis, in order to understand the operating costs and benefits and provide a scientific configuration tool when bringing in medical technology. Results: The configuration of large medical equipment has some problems, such as the uneven distribution of medical resources, equipment shortage, blind purchase of high-end equipment, low localization rate and so on. These problems will directly lead to the unreasonable allocation and the waste of medical resources. Conclusion:The configuration of large medical equipment must comply with the relevant provisions of the state by the HTA and other scientific methods, so as to improve the level of investment decision-making. It will make the use of medical resources efficiently and reasonably.

Objective Investigate the significance of the antibody and antigen detection of Rh blood group.Methods Detecting Rh blood group antigen phenotypes and screen Rh blood group antibodies in 2 700 inpatients from August 2012 to May 2013.Re-sults Rh blood group antigen phenotypes in descending order of propotion were as follows:CCDee,CcDEe,CcDee,ccDEE,CCDEe. 5 antigen genes in descending order of frequency were D,e,C,c,E.Conclusion For donors and donees,in addition to routine tests, the other 4 types of antigen and antibodies in Rh blood group should be detected too,which helps avoid secondary transfusion diffi-culty because of the immunity antibodies generated in blood transfusion.

Objective To investigate the changes of expression of N-methyl-D-aspartate receptor(NMDAR)and mitogen activated protein kinase(MAPK)in Alzheimer disease(AD)rat model. Methods AD rat model was established by injection of amyloid-beta protein 1-40 1?l(10 g/L)into hippocampus of rat.NMDAR-mRNA and MAPK protein were immunostained by in situ hybradization histochemistry and immunohistochemistry respectively.Learning and memory ability,LTP were determined by Morris water maze and electrophysiological methods respectively. Results The escape latent was prolongated in Alzheimer rats two weeks after injection of A? than in control rats and in rats before the injection of A?(P

Aim To investigate the effects of maternal chronic aluminum exposure on memorial behaviour and hippocampal intracellular Ca2+ concentration ([Ca2+]i)on their offspring after the induction of LTP(long-term potentiation). Methods Adult Wistar rats (150~200 g) were exposed to aluminum by drinking distilled water, the concentration of AlCl3 is 0.015 mol?L-1(2 g?L-1) and 0.03 mol?L-1(4 g?L-1) aluminum chloride (AlCl3) solution, respectively, for 30 days prior to mating and during the whole gestation and suckling period. Their offspring were distributed into three experimental groups: control group; two exposed groups (represented by 0.2%-Al and 0.4%-Al ) administrated aluminum exposure ended at postnatal day 21. The brain tissue and blood aluminum levels were measured by Atomic absorption spectrometry (AAS). Memorial ability of the offspring was tested by Step down test.[Ca2+]i was measured by the technique of Fura-2/AM calcium ions fluorescence indicator. Results The mean aluminum content in blood and brain tissue was significantly higher than the control group(P0.05), but was significantly decreased in 0.4%-Al exposed group(P

ObjectiveTo study the relationship between C-erbB-2 and estrogen (ER) and progesterone (PR) receptors, and the relationship between C-erbB-2, ER, PR with histologic grade. MethodsTo detect ER, PR and C-erbB-2 states by using immunohistochemical analysis and fluorescence in situ hybridization for C-erbB-2 in 163 unselected invasive breast carcinomas. ResultsC-erbB-2, ER ,PR were expressed in 21.5％ ,64.4％ ,44.2％ of 163 cases respectivly . 5 pure mucinous carcinomas , 3 tubular carcinomas and 1 micropapillary carcinoma were ER + ( 100.0％ ) 、C-erbB-2 - ( 100.0％ ) and PR + (40.0％ ,66.7％, 100.0％ ). C-erbB-2 was positive in 22.3％ of grade Ⅱ and 27.0％ of grade Ⅲ invasive ductal carcinomas and negative in all grade Ⅰ invasive ductal carcinomas.ER and PR expression were decreased significantly in C-erbB-2 + tumors compared with C-erbB-2 - tumors( ER,25. 7％ vs 75.0％ ; PR,25.7％ vs 49.2％ ). Although ER or PR expression is decreased in C-erbB-2 + tumors, a substantial proportion of them still express ER or PR. ConclusionC-erbB-2 overexpression or amplifcation was limited to a minority of invasive breast carcinomas. Tumour grade was an independent predictor for ER expression. ER was expressed in small number of high-grade and in large number of grade Ⅰ invasive ductal carcinomas. C-erbB-2 overexpression or amplification essentially was limited to grades Ⅱ and Ⅲ ductal carcinomas and correlated inversely with ER or PR expression.

Objective To evaluate the effect of rehabilitation training on dysphagia and trismus in patients with nasopharyngeal carcinoma after radiotherapy.Methods Fony-three post-radiotherapy nasopharyngeal carcino-ma patients were divided into a rehabilitation group and a control group.Both groups were subjected to routine treat-ment,while the rehabilitation group received rehabilitation training in addition.The patients were assessed with a wa-ter-swallowing test of swallowing.Late effects of normal tissues/subjective and objective medical analysis(LENT/SOMA)scored and inter-incisor distance were measured to assess trismus before and after treatment.Results The rehabilitation group displayed significant improvement in swallowing as well as increased inter-incisor distance.Con-clusions Rehabilitation training can improve swallowing,prevent or delay trismus and improve the quality of life of patients.

Objective To explore molecular mechanism and the curative effect of Yisuishengxue powder and its function of the hepersensitive site 2 (HS2) in ?-globin gene cluster locus control region binding with nucleoprotein.Methods After 3 months treatment of Yisuishengxue powder, nucleoprotein was extracted from the morrow cell before and after treatment. The HS2 DNA probes was combined with nucleoproteins.Electrophoresis gel mobile lag was utilized for observing the mobile velocity of DNA segment.Observe the mobile velocity of DNA probes.Results The mobile velocity of probes combined with nucleoproteins before treatment was different form that of the controls, while it was very close to the controls after treatment.Conclusions It is suggested that this compounding medicine might affect the DNA segment of HS2 site in ?-LCR binding with nucleoprotein GATA-1, which may be one molecular mechanism of Chinese herb therapy.

A mutant strain RZ13 with high lipase productivity was obtained through treating the Rhizopus sp. RXF12 by UV and microwave,and its activity was 2.62-fold of the original one. The high lipase productivity of the mutant strain could be inherited after repetitious subcultures.The optimal culture conditions of the RZ13 for producing lipase were studied.The lipase with highest activity (67.32U/ml) was obtained on the conditions of 25℃,pH 8.0,5 %(v/v) single spore suspension (1?107spore/ml) and 120 r/min for 84h,and stable under 40℃ and pH 8.5. In addition,the lipase was immobilized by adsorption onto Mg-Al hydrotalcite at 25℃ for 4 h by screening carriers and optimizing the immobilization. The results showed that the optimal reaction temperature and pH were 35~55℃ and 7.5~9.0,respectively,much wider than the free lipase.

OBJECTIVE: To analyze the characteristics in the incarcerated inmate's death, investigate the main cause of death of the incarcerated inmate and provide some information for forensic investigation. METHODS: The cases from the forensic medical center of Shanxi Medical University from 2005 to 2013 were selected. The statistical analysis was performed by using the incarcerated inmate's gender, age, cause of death, manner of death, and disease as the markers. RESULTS: There were 100 men, 5 women in the 105 incarcerated inmates; the age range was from 16 to 65 years; Inmates were mostly died of natural diseases, mainly in the respiratory and cardiovascular diseases; the main unnatural death was suicide with a rate of 54.5%. CONCLUSION At present, most incarcerated inmate's death are due to natural diseases. The prison should improve incarcerated inmate's lives, work and health care conditions, and strengthen supervision of law enforcement.
