OBJECTIVE:To evaluate the status quo and the tendency of antiepileptic drugs used in6Children's Hospitals in the Yangtze Valley.METHODS:Data on drug variety,sales volume,manufacturers of antiepileptic drugs used in6Chil?dren's Hospitals in the Yangtze Valley during2002～2004were analyzed statistically.RESULTS:Sodium valproate and topi?ramate took a bigger share in the market with the proportion of both to the antiepileptic drugs in sales volume at about40%.The old variety still took the lead in the clinical drug consumption while the momentum for the consumption of new one was quite fine.CONCLUSION:There are only a few varieties of antiepileptics now yet the sales volume of which is on the rise,therefore,of which there is still prospect of development.

Objective To investigate the psychological state of patients with aplastic anemia. Methods 54 patients with aplastic anemia and 50 health persons were tested with the questionnaires of SAS and EPQ. Results The score of anxiety and the incidence of anxiety in aplasitc anemia patients were much higher than that in health persons. The score of N in the EPQ was much higher in aplasitc anemia patients than that in health persons. Conclusion Patients with aplastic anemia obviously have the incline of nervosity. It is the nurse' duty to adjust patients' negative emotion to help them recovering from the disease.

Objective To investigate the HAART in PMTCT different intervention time of blocking effect. Methods 49 cases who received out -patient examination and hospital delivery of HIV positive pregnant women were selected,the intervention time pregnant 14 weeks,pregnant 28 weeks.The patients were divided into three groups,group A (n =20),group B (n =19),group C (n =10).The safe delivery,the newborn 50 out of 18 months of tracking and detection,and the results were analyzed.Results Three groups of antiviral HIV infected maternal immune status (P >0.05 ),antiviral CD +4 cell number variation had no statistical significance (P >0.05 ),the blocking effect was A group of infants 0 infection.In group B,1 cases of infant infection.Group C 2 cases of infant infection.Compared between group A and group B,the difference was not statistically significant (χ2 =0.97,P >0.05),compared between group B and group C,the difference was not statistically significant (χ2 =1.40,P >0.05). Compared between group A and group C,the difference had statistical significance (χ2 =4.08,P <0.05 ). Conclusion HAART for blocking HIV mother to child transmission effect is very significant,if in 14 weeks pregnant initiation of HAART,the infant HIV infection rate is lower,recommended the early antiviral treatment and after childbirth to strengthen follow -up and management.

The treatment effect of primary and metastatic hepatic carcinoma after local intervention?al therapy is closely related to the prognosis of patients. Traditional imaging modalities such as CT, MRI and ultrasound can only provide anatomical information in monitoring treatment response. In recent years, PET/CT has been widely used in monitoring treatment response for tumors. Many studies have compared the effi?cacy of PET/CT with that of traditional imaging modalities in monitoring the response of primary and meta?static hepatic carcinoma after interventional therapy. This review summarizes recent progress in this field.

Objective To analyze the clinicopathologic features of patients with pathologic T2-3N0 thoracic esophageal squamous cell carcinoma (ESCC) and correlation to their prognosis.Methods The clinicopathologic data of 422 patients with pathologic T2-3N0 thoracic ESCC,who were treated with surgery were analyzed.Cumulative survival rate was analyzed by the Kaplan-Meier method and compared by Log-rank test.Cox regression model was used for multivariate prognostic analysis.Results The overall 1-,3-and 5-year survival rates were 89.3 ％,63.5 ％ and 52.5 ％,respectively.Univariate analysis revealed that the factors affecting the prognosis included gender (x2 =7.45,P ＜ 0.01),depth of invasion (x2 =7.79,P ＜ 0.01) andtissues differentiation (x2 =15.81,P ＜ 0.01).They were also independent prognostic factors according Cox regression multivariate survival analysis.Conclusion The gender,depth of invasion and differentiation should be independent prognostic factors of pathologic T2-3N0 ESCC.Surgery is still the standard treatment for pathologic T2-3N0 esophageal cancer.

Objective To investigate the effects of antisense phosphothioate oligodeoxynucleotides (AS-ODNs) W086 on drug-resistant gene CTX-M expression in Escherichia coli producing extended-spectrum β-lactamases(ESBLs).Methods AS-ODNs liposome was introduced into the purpose bacteria B052.The total colony forming unit(CFU) was counted.The bacteria growth curve was drawn by microplate reader.The inhibition effects of AS-ODNs on the expressions of drug-resistant gene CTX-M were observed by RT-PCR in B052.The minimal inhibitory concentration(MIC)was determined by fluid dilution method.Results significant growth inhibition of cells treated with W086 was observed as compared with those in cells in control treated bacteria.The number of B052 colonies significantly decreased in all W086 treated groups in a concentration dependent manner (P ＜ 0.05),while CFU of B052 was not influenced in simple liposome group,simple W086 group and controlled chain group.The expression of CTX-M was selectively inhibited.Conclusion Efficiently and specificly blocking expression of CTX-M mRNA,AS-ODNs reverses the multiple drug resistance of B052.It indicates that AS-ODNs provides a new viable strategy to reverse antibiotic resistance problem.

By studying the developmental strategy of the revonal medical science and technology and implementation condition from 2001 to 2004 as well as systematically studying the national policy of the scientific and technical field,we proposed the developmental strategy of medical science and technology in Shanghai that the priority for the introduction,the application and the popularization of new or suitable technology should be given,also continuous advancement in technology should be kept.As a result,it is possible to provide the people a safer,more effective,convenient and moderately priced public health and basic medical service.During the past 5 years.we made an experimental work in selected Pudong in Shanghai.It Was proved that the strategy tallies with the actual situation of Pudong and is effectual in practice.

Objective • To reveal the effect of denatured collagen type on the endothelial cell proliferation, migration, and angiogenesis-related proteins expression. Methods • Human umbilical vein endothelial cells were cultured on the plates coated with normal collagen (normal collagen group), half concentration normal collagen (half collagen group) or denatured collagen (denatured collagen group). CCK-8 assay was performed to test cell proliferation ability two days later. The effect of collagen on cell migration was measured by scratch test. The expressions of membrane-type 1 matrix metalloproteinase (MT1-MMP) and vascular endothelial growth factor (VEGF) were detected by Western blotting. The expressions of angiopoietin 1 (Ang-1) and Ang-2 were measured by ELISA. Results • CCK-8 results showed that the proliferation activity of denatured collagen group was significantly higher than that of normal collagen group and half collagen group (P<0.05). Cell migratory capacity was increased in denatured collagen group, of which the scratch was almost covered after 16 h. The protein expressions of MT1-MMP and VEGF were significantly higher in denatured collagen group than those in the other two groups (P<0.05), in which the concentration of Ang-2 was also higher than that in normal collagen group (P<0.05). However, no significant difference was found in the concentration of Ang-1 among the three groups. Conclusion • Denatured collagen type can promote proliferation, migration and MT1-MMP, VEGF, and Ang-2 expressions in endothelial cells, suggesting that collagen denaturation may play an active role in the process of angiogenesis during wound healing.

Anaerobic bacteria are responsible for many cases of infection,but anaerobic bacteria are not detected in most of clinical labs in China yet.It is very important to intensify the test for anaerobic bacteria in clinical laboratory.Attention to detection for anaerobic bacteria should be paid.
