OBJECTIVE To evaluate the bioethical principles which should be followed in the epidemiological study of AIDS.METHODS Practicality of bioethical principles in epidemiological study of AIDS was evaluated by theoretical analysis method.RESULTS The important principles in the epidemiological study of AIDS are respect,beneficence/nonmaleficence and justice principles.CONCLUSIONS Following bioehical principle is the basis of epidemiological study of AIDS.

Analysised the transmission routes of AIDS in hospital,preventive strategies and existing ethic problems.Putting forward the importance of respecting the proper right of AIDS patients and health care workers in the prevention of nosocomial-transmitted HIV.On the basis of scientific study,strengthening the propagating of the knowledge of AIDS in the whole society,respecting the right and statue of AIDS prevention and timely treatment among both patients and health care workers.Respecting their medical treatment right and secrets,detecting HIV of patients on the informed consent.Respecting health care workers' right,providing profession guide and preventive strategies for prevention and control of nosocomial-transmitted AIDS.

From the perspective of hospital administrators, the paper reveals a variety of failures in the establishment and application of the hospital information system and analyzes the causes of the failures.

Objective To investigate the water equivalent of two solid water phantoms.Methods The X-ray and electron beam depth-ion curves were measured in water and two solid water phantoms,RW3 and Virtual Water.The water-equivalency correction factors for the two solid water phantoms were compared.We measured and calculated the range sealing factors and the fluence correction factors for the two solid water phantoms in the case of electron beams. Results The average differenee between the measurled ionization in solid water phantoms and water was 0.42%and 0.16%on 6 MV X-ray(t=-6.15.P=0.001and t=-1.65,P=0.419)and 0.21%and 0.31%on 10 MV X-ray(t=1.728,P=0.135 and t=-2.296,P=0.061),with 17.4%and 14.5%on 6 MeV electron beams(t=-1.37.P=0.208 and t=-1.47,P=0.179)and 7.0%and 6.0%on 15 MeV electron beams(t=-0.58.P=0.581 and t=-0.90,P=0.395).The water-equivalency correction factors for the two solid water Dhantoms varied slightly largely,F=58.54,P=0.000 on 6 MV X-ray,F=0.211.P=0.662 on 10 MV X.ray,F=0.97.P=0.353 on 6 MeV electron beams,F=0.14,P=0.717 on 15 MeV electron beams.However,they were almost equal to 1 near the referenee depths.The two solid water phantoms showed a similar tread of Cpl increasing(F=26.40,P=0.014)and hpl decreasing(F=7.45,P=0.072)with increasing energy.Conclusion The solid water phantom should undergo a quality control test before being clinical use.

Objective:To study the ethical attitude of infertility patients and the public towards the artificial insemination technology,with the aim of its better clinical application.Methods:A questionnaire among 220 infertility patients and 720 persons of different social walks,followed by a contrastive study of the results.Results:There is distinctive difference(P

Objective To evaluate the effect of recombinant expressing plasmid pCMV-KAI1 on the proliferative ability of PANC Ⅰ and MiaPaCa Ⅱ pancreatic cancer cells, and to observe the suppress metastatic mechanism of KAI1 gene in the malignancy.Methods The plasmid pCMV-KAI1 was transfected into the human pancreatic cancer cell lines PANC Ⅰ and MiaPaCa Ⅱ with liposome. The proliferative ability of these two pancreatic cancer cell lines were analyzed with MTT and colony-forming test, the cycle pattern was assayed by flow cytometry.Results After KAI1 expressing plasmid tranfected into PANC Ⅰ and MiaPaCa Ⅱ, the cell growth rates of the two cell lines were reduced by 40.59% and 65.84% respectively compared with the control cells (P

objective To investigate the effect of the prognosis of multiple organ dysfunction syndrome(MODs) through APACHE Ⅱ and APACHE Ⅲ.Methods The relations of APACHEⅡ,APACHEⅢ,the occurrence rate and number of organs failure and the dangerous extent and prognosis of MODS are studied between survival group and death group through the review research of 45 cases of MODS.Results APACHE Ⅱ andⅢ,age and genrating rate of failure organS are significant difference between surviral group and death group(P＜0.05)in MODS.The predicting correlation of APACHE Ⅱis not significant difference between number of organs failure and mortality of MODS(P＞O.05),but the predicting correlation of APACHE Ⅲ is significant difference between number of organs failure and mortality of MODS(P＜0.05).Conclusion The study showed APACHEⅢis better than APACHEⅡ on the dangerous extent and prognostic evaluation in MODS.

Objective To observe the effect of Weidongfang and hydrotalcite in treatment of bile reflux gastrifis.Methods Bile reflux gastritis were randomly assigned to 2 groups.30 eases in the Weidongfang group were treated with Weidongfang and hydrotalcite;30 cases in the mosapride group were treated with mosapride and hydrotalcite;and the course of treatment was 4 weeks for all.The clinical symptoms of bile reflux gastritis,the classify of extent of bile reflux and the accumulated points of pathological change of the gastric mucosa below gastroscope were evalumed before and after treatment.Results The significant and total effective rate in the Weidongfang group were 33.3% and 86.7%.Mosapride group 43.3% and 83.3%.Butthe classify of extent of bile reflux and the accumulated points of pathological change of the gastric mucosa of Weidongfang group were Similar to Mosapfide group below gastroscope.Conclusion Weidongfang and hydrotalcite were effective medicine in treatment of bile reflux gastritis.

Objective To explore the effect of zingiberol combined with purple burn ointment in prevention of chemotherapy- induced phlebitis. Methods 200 cases of peripheral intravenous chemotherapy were randomly divided into the experimental group and the control group with 100 cases in each. The control group was given conventional infusion chemotherapy drugs, the experimental group used zingiberol combined with purple bum ointment to embrocate the skin around the vein to prevent phlebitis. After chemotherapy, the results were observed and recorded. Results The incidence of phlebitis in the experimental group significantly reduced compared with the control group. Conclusions Embrocation with zingiberol and purple burn ointment can prevent chemotherapy-induced phlebitis, which is simple with significant effect.
