The cost-benefit analysis in large-scale medical equipment are explored.The management of medical equipment cost adopts methods of pre-forecasting,control in the course,and post-evaluation.The utilization of this analysis method shows active guiding significance.

Supplementary concept records ( SCB ) can effectively supplement and expand MeSH by forming the mapping between SCB and MeSH. Chinese herbal medicine terms indentified by MeSH Browser in SCB were analyzed in aspects of their distribution,single medicine,abstracted compositions,compound prescription,classical prescription, slef-made prescription, and use frequency,which showed the supplementary concepts in relation with Chinese herbal medicine and the existed problems. Suggestions were put forward for the use of Chinese herbal medicine terms in MeSH SCB, such as promoting their standardization, and use of standard terms when scientists publish their papers and retrieve papers from databases.

AIM:To investigate the expression of estrogen receptors in myocardium of ovariectomized female rats.METHODS:One week after bilateral ovariectomy,the female SD rats were divided into 3 groups randomly:OVX +estrogen(0.15 mg/kg,s.c.),OVX + normal sodium and control.After 4 weeks of treatment,the expression of estrogen receptors in the myocardium were evaluated by Western blotting.RESULTS:After ovariectomy,serum estrogen decreased significantly,compared with control[(88?22 vs 403?59)pmol/L,P

Objective To express the immunodominant epitopes of the branched chain 2 oxo acid dehydrogenase complex (BCOADC), the pyruvate dehydrogenase complex (PDC), the 2 oxo glutarate dehydrogenase complex (OGDC) and a triple hybrid clone (designated as BPO), and use BPO as a tool for the detection of M2 specific for primary biliary cirrhosis (PBC). Methods The cDNA fragments encoding the M2 reactive epitopes of BCOADC, PDC and OGDC were amplified using PCR with total RNA extracted from human peripheral mononuclear blood cell. The fragments were cloned into pQE 30 and then transformed into plasmid E.coli M15. Its products were induced by isopropylthio ? D galactoside and confirmed with SDS PAGE and Western blot. Results Four specific proteins induced from the transformants containing the fused plasmid were shown to have antigenic reactivity with PBC sera, but not with normal control sera. Conclusions We succeeded in expressing three immunodominant epitopes and a hybrid clone which can be used as a powerful and specific method for the diagnosis of PBC.

Objective To identify the typical imaging features of steatocystoma multiplex on mammography.Methods Mammographic findings in 9 patients with clinical and pathological diagnosis of steatocystoma multiplex were analyzed along with a review of the current literature.Results Four of the nine patients with steatocystoma multiplex had a positive family history.Nine patients showed multiple,round,thin-walled fatty,radiolucent nodules with well-defined margin.These nodules are located in the superficial layer of the axilla bilaterally.They are also seen on the skin of breast(7 cases),the anterior chest wall (4 cases) and the upper arm (3 cases).Conclusion Recognition of the characteristic mammographic features of Steatocystoma multiplex is important in the management of these patients.

Objective To investigate the clinical value of docetaxel combined with psychological intervention in elderly patients with advanced non-small cell lung cancer. Methods the control group received docetaxel chemotherapy, and the study group received psychological intervention on the basis of docetaxel chemotherapy. The efficacy, adverse reactions and adverse emotions of two groups of elderly patients with advanced non-small cell lung cancer were recorded. Results the total efficiency was up to 54.17％, only 41.67％ of the control group (P<0.05); toxic and side effects in the research group alopecia, gastrointestinal reaction, rash was significantly lower than the control group did not received psychological intervention (P<0.05); the control group after treatment SAS, SDS score increased than before more than the study group (P<0.05). Conclusion On the basis of docetaxel in the treatment of elderly patients with advanced non-small cell lung cancer, the use of appropriate psychological intervention measures can significantly alleviate the negative emotions, and have positive significance to ensure the effectiveness and safety of chemotherapy.

Objective To make sure the exact curative effect of using Kasai distillate to moderate the dysporia for patients with gynecological operation. Methods Divided 152 patients with dysporia into observation group and control group randomly, each group have 76 cases. Using Kasai distillate 80 ml in observation group, 40 ml in control group. Compare the condition of defecation in these 2 groups after using Kasai distillate 15～30 minutes. Results There were 74 cases and 36 cases in observation group and control group respectively obtain significant curative effect, ?~2=40.7, P

The article explored the cause of recovery failure by adopting advanced simu-lation system(ECS) in the teaching of ‘recoveing of neonatal asphyxia’and put forward some improvement methods and counter measures.Marking full use of the advantages of ECS,designing the training course with specifit roles and objectives,paying attention to the guidance of organiza-tion and exchange as well as the training of cooperative team are the key to improve the skills of neonatal asphyxia recovery in obstetrical pediatric and the teaching quality.

Objective To compare the biochemical and clinical features of antimitochondrial antibody (AMA) positive and negative primary biliary cirrhosis (PBC),and to compare the sensitivity of both the detection of M2 antibody using enzyme linked immunosobent assay (ELISA) with antigen expressed from human sources,and the detection of AMA using conventional indrect immunofluorecence for diagnosing PBC.Methods AMA and M2 antibodies were tested in 63 patients with diagnosed PBC.Results Serum AMA positive rate in PBC patients was 81%(51/63) compared with 100%(63/63) of M2 positive rate.Antinuclear and anti smooth muscle antibodies(ANA and ASMA) were more frequently positive in the AMA negative patients (83% vs 35%,and 42% vs 4%, P

Objective To investigate the role of survivin and P53 in apoptosis of gastric adeno- carcinoma,as well as its relationship with the clinicopathologic features and the prognosis.Methods The gas- tric tissue microarrays were composed of those from 100 cases of gastric cancer and 30 controls.At these tissue microarrays,expressions of survivin and P53 were investigated immunohistochemically,and tumor cell apoptosis index was examined by TUNEL method.Of the 100 cases,47 cases were followed-up from 14 months to 13 years,in which the survival was analyzed.Results Two paraffin-embedded gastric carcinoma tissue micro- arrays were successfully constructed,including 114 and 116 tissue spots,respectively.Immunohistochemical analysis showed that survivin was expressed in 78 cases (78%).No expression of survivin was detected in control tissue (P0.05).In the 47 cases with followed-up data,univariant analysis revealed that the survival was correlated with invading of vessel and nerve,TNM stages,and expression of survivin.The histological grades and expression of P53 were not related to prognosis.However,Cox stepwise proportional hazards analysis showed that only TNM staging and survivin status retained significant independently in prospecting prognosis.Conclusions The expression of survivin was associated with the pathologic features,TNM stages and prognosis in gastric carcinoma,indicating that overex- pression of survivin may be a poor prognosis factor for gastric carcinoma.
