OBJECTIVE:To compare the cost-effective ratios between Granisetron and Ondansetron in the prevention of Cisplatin-induced nausea and vomiting.METHODS:In a randomized auto-controlled design,36patients receiving chemotherapy with Cisplatin were divided into2groups to compare the antiemetic effects and toxicity between Granisetron and Ondansetron and to carry out cost-effectiveness analysis.RESULTS:Granisetron could effectively prevent Cisplatin-induced nausea and vomiting and its antiemetic effect was comparable to that of Ondansetron.The average effective rates in preventing nausea and vomiting of Granisetron and Ondansetron were75.9%,77.8%and79.7%,75.0%respectively,and there were no significant differences between two drugs.The toxic reactions of Granisetron were slight.In cost-effectiveness analysis,Granisetron was better than Ondansetron.CONCLUSION:Granisetron is a safe,effective,economical antiemotic in chemotherapy of cancers.It is worth popularizing the application.

Objective To establish GC and GC/MS qualitative and quantitative analysis methods for identification of cocaine cases. MethodsChoosed and optimized the best analysis parameters of cocaine by GC/MS and GC. We prepared 0.10, 0.20, 0.40, 0.60, 0.80, 1.00, 1.20mg/ml ethanol solution of cocaine standard which all contained 0.6mg/ml diazepam (internal standard) to study the analyse standard curve and the detection limit of cocaine drugs. ResultsThe linear equation of cocaine by GC/FID was Y=1.055X-0.0021, R2=0.9999; That of GC/NPD was Y=0.556X-0.0016, R2=0.9996; The detection limits of cocaine were 10ng by GC/FID method and 2ng by GC/NPD method. On the other hand, we used GC/FID and GC/NPD methods and internal standard to quantitate the cocaine drugs sized by police respectively, the result of concentration was 72%?2.3%. The quantitative data of both methods had good repeatability. ConclusionThe methods established are useful to examine and identify cases of cocaine.

146 patients with Non-Hodgkin's lymphoma of the nasal cavity were treated by: radiotherapy only (76 patients) and chemotherapy plus radiotherapy (70 patients). The overall 5- and 10-year survivals were 58.2% and 50.7%. Those with tumor extending into the neighboring organs or tissues gave a 5- year suivival of 30.3%. The differences therein is statistically significant (P

Objective To investigate the efficacy of recombinant human erythropoietin(rhEPO)in preventing and reversing dys- function of retinal neurons in streptozotocin(STZ)-induced diabetes in rats.Design Experimental study.Participants The early stage of diabetic rats.Method Two weeks after STZ(60 mg/kg,i.p.),diabetic rats were administered rhEPO(5000IU/kg)injection three times weekly for 2 weeks.Retinal samples of STZ-induced diabetic rats with or without rhEPO and controls were prepared for ultrathin sec- tions and subsequently photography by transmission electron microscope.Also the content of glutamate in retina of the rats was detected with high-performance liquid chromatography.Main Outcome Measures The ultrastructure of rat retinas and the content of retinal glutamate.Results Mitochondrial metamorphosis in ganglion cells occurred in STZ-induced diabetic rats without rhEPO.Obvious mito- chondrial metamorphosis couldn′t be found in STZ-induced diabetic rats with rhEPO treatment.Retinal glutamate at the end of the 4th week of STZ-induced diabetic rats had increased obviously comparing with the normal rats(P

The effect of iodinated contrast on thyroid function and auto-antibodies after a single percutaneous coronary intervention (PCI) was explored.In 96 patients with randomly selected PCI,serum TSH,T3,T4,thyroid peroxidase antibody (TPOAb),thyroglobulin antibody (TgAb) were determined preoperatively as well as by 3-6 months postoperatively.After PCI,the level of TSH,T3,T4,showed no significant changes; TgAb,TPOAb which were positive preoperatively,after 3-6 months were statistically increased(P＜0.05).Iodinated contrast in PCI has no significant influence on thyroid function and auto-antibodies after 3-6 months.

Objective To evaluate MRI in the diagnosis of the bone contusion of the knee joint and its clinical significance.Methods Using special coil for knee joint,coronal,sagittal,axial and oblique sagittal plane scanning with fast spin-echo sequence(T_1WI,T_2WI,PDWI+FS)was performed on knee joint in 205 patients in three days after injury.According the distributing bone marrow edema and injury mechanism,bone contusion were classified five types as pivot shift injury,clip injury,dashboard injury, hyperextension injury and lateral patellar dislocation.Results One hundred and forty-five cases of the 205 patients were found bone marrow edema without fracture on X-ray films.Among them,pivot shift injury was found in 43 cases accompanied with anterior cruciate ligament rupture in 30 cases,tear of the posterior horn of the lateral or medial meniscus in 12 and tears of the medial collateral ligament in 8 cases;clip injury in 53 cases accompanied with anterior cruciate ligament rupture in 10 cases,tear of the posterior horn of the lateral or medial meniscus in 15 and tears of the medial collateral ligament in 38 cases;dashboard injury 40 cases accompanied with posterior cruciate ligament rupture in 16 cases,hyperextension injury 9 cases accompanied with anterior cruciate ligament rupture in 2 cases,posterior cruciate ligament rupture in 5 cases.No lateral patellar dislocation was found.Forty-eight of 145 patients had undergone arthroscopy, 43 cases(89.6%)of them were in accordance with MRI diagnosis.Bone contusion were defined as geographic regions of abnormal signal intensity,that is,low signal intensity in T_1-weighted images and high signal intensity in PD-weighted or T_2-weigeted images with fat saturation.Conclusion MRI can accurately display the location and area of bone contusion of the knee joint as well as its adjunctive structure injury and deduce their injury mechanism.MRI should be used routinely for knee trauma.

At present, the monitoring methods fwor intracranial pressure adopted in clinical practice are almost all invasive. The invasive monitoring methods for intracranial pressure were accurate, but they were harmful to the patient's body. Therefore, non-invasive methods for intracranial pressure monitoring must be developed. Since 1980, many non-invasive methods have been sprung out in succession, but they can not be used clinically. In this paper, research contents and progress of present non-invasive intracranial pressure monitoring are summarized. Advantages and disadvantages of various ways are analyzed. And finally, perspectives of development for intracranial pressure monitoring are presented.

The relationship between acupuncture and stress is discussed from three aspects, including is it possible for acupuncture stimulation to be a stressor, whether acupuncture will start stress reaction, and whether acupuncture effects contain some stress factors. It is believed that correct acupuncture manipulation will not cause stress response, however, under some circumstances, such as inaccurate manipulation, improper treatment or patients who are very nervous but do not receive effective intervention, acupuncture is likely to cause stress response. Acupuncture-induced stress response is totally different from acupuncture anti-stress. The possible stress factors in acupuncture effect are explored, which can provide a new angle for the research on action mechanism of acupuncture. From the view of stress to review acupuncture treatment, there are three enlightenments: emphasizing on communication between doctors and patients, avoiding over-pursuit of deqi and focusing on analysis of the body constitution.

Aleutian mink disease parvovirus (AMDV) causes a persistent infection associated with immune complex disease, hypergammaglobulinemia, and high levels of antiviral antibodies. Despite the presence of an antibody, the virus is not cleared in vivo. Pre-existing antibodies may enhance viral infections, by Fc-receptor-mediated antibody-dependent enhancement (ADE), but the mechanism that underlies ADE has not been fully defined. Three models have been proposed, including: (1) interactions between antibody and FcR, complement C3 fragment and CR, or between C1q and C1qR, which promotes viral attachment to cells; (2) suppression of IFN-gamma-mediated host-cell antiviral gene expression by the upregulation of negative regulators of pathogen pattern recognition; and (3) the promotion of early IL-10 secretion. In addition, the role of cytokine IL-6 in ADE mediated disease development is discussed, to facilitate a better understanding of the pathogenesis of AMDV infection, as well as give insights into rational vaccine design approaches.
