Objective To analyze the distribution status of soil-transmitted nematodes infection for prevention and treatment.Methods The inquiry field test and grade random sampling were emplyed on a group of people naturally selected in Shanxi Province.The people were examined through pathogen test and statistical diagnosis.Results A total of 7 726 people were investigated.Soil-transmitted nematodes infection rate was 18.86%.Ascaris,enterobius,trichuris,and hookworm was 15.87%,11.46%,0.82%,and 0.04% respectively.The intensity of ascaris infection was 97.74%,1.60%,and 0.66% respectively in light,moderate,and serious conditions,and that of trichuris infection was 88.89%,7.41%,and 3.70% respectively in light,moderate,and serious conditions.Conclusions Soil-transmitted nematodes infection rate is lower than that in 1992.Its cases are mainly distributed in rural areas and schools,closely related to education level.Improving water-drinking conditions and personal hygiene is still key to the prevention and control of the infections.

Objective To analyze the reproducibility of keratometry and astigmatism measured by the VERION Digital Guidance System and the comparability of VERION with iTrace,Lenstar LS900 and manual keratometer.Methods The keratometry of 62 cataract patients were measured using four different devices.The steep keratometry (Ks),flat keratometry (Kf),astigmatic magnitude,astigmatic axis,cylinder at 0-degree meridian (vector component,J0) and cylinder at 45-degree meridian (vector component,J45) from each machine were recorded and analyzed.The three repeated measurements and the results of VERION system with other three devices were compared to analyze the reproducibility and comparability of VERION system.Results Reproducibility:Intraclass correlation coefficients and Cronbach's alpha values were higher than 0.9 for Ks,Kf,astigmatic magnitude,astigmatic axis,J0 and J45 measured by the VERION system (all P ＜ 0.001).Comparability:The results of Ks and magnitude of astigmatism of VERION were larger than the iTrace (all P ＜ 0.05) in the paired-samples t test.There was no statistical difference for the rest of parameters (all P ＞ 0.05).The Bland-Altman graphs revealed the 95％ limits of agreement (LOA) of J0,J45 and the astigmatic axis between VERION and iTrace were (-0.31-0.35) D,(-0.25-0.31) D and-13.5 °-12.3 °,respectively;There was no statistical differences for all parameters except for J45 in the paired-samples t test between the VERION and Lenstar LS900 (all P ＞ 0.05).The Bland-Altman graphs revealed the 95％ LOA of J0,J45 and the astigmatic axis were (-0.25-0.31)D,(-0.27-0.36) D and-13.5°-11.0°,respectively;There were statistical differences for the results of Kf and magnitude of astigmatism between the VERION and manual keratometer (all P ＜ 0.05).The Bland-Altman graphs revealed the 95％ LOA of J0,J45 and the astigmatic axis between VERION and manual keratometer were (-0.38-0.35) D,(-0.41-0.42) D,-12.6°-16.4°,respectively.Conclusion The VERION system is a reliable system for the measurement of keratometry and astigmatism.The keratometry and astigmatic magnitude of the VERION system have a good agreement with the iTrace,Lenstar LS900 and manual keratometer.However,the astigmatic axis measurements are significantly different among the four devices.

Background and purpose:With widely use of anthracyclines,patients are easily failed to respond to anthracyclines baseal regimens chemotherapy.Docetaxel and capecitabine(xeloda)are usually considered as the most active agents in breast cancer and are often used as adjuvant chemotherapy.In this study,we evaluated the efficacy and toxicity of docetaxel and xeloda combination regimen in the treatment of patients with metastatic breast cancer and previously treated with anthracyslines.Methods:64 patients who previously failed to respond to adriamycin based chemotherapy received docetaxel and xeloda combination regimen,docetaxel 75 mg/m2 ivgtt,day 1;xeloda 1 250 mg/m2,twice daily,day 1-14.The regimen was repeated every 21 days and the clinical response was recorded after 2 cycles.The effective patients received at least four cycles.Results:In 64 patients,the overall response rate was 60.9%,with 6 patieuts CR and 33 patients PR.The most frequent treatment-related adverse events were leukopenia, fatigue,nausea,vomiting and hand-foot syndrome.The main reactions were myelosuppression,Ⅲ-Ⅳwas 45.8%. Conclusion:Good clinical efficacy were achieved in the therapy of metastatic breast cancer with docetaxel and xeloda combination regimen and toxic reactions are tolerable.

Interdigitating dendritic cell sarcoma (IDCS)is a rare malignant tumor of the dendritic cell, derived from the hematopoietic tissue.The major clinical manifestation of IDCS is superficial lymphadenopathy, and the enlarged lymph nodes may appear in some atypical ereas,such as the lung,kidney,bladder and the pleura,etc.With the development of the pathological diagnosis and the application of immunohistochemical staining and electron microscopes,the case detection rate is apparently improved.With the high degree of malignant,rapid progress and poor prognosis of the disease,currently,surgical therapy is still the main approach to the treatment of IDCS.

ABSTRACT:Objective To explore the differential expression of microRNAs (miRNAs)in steroid-induced osteonecrosis (ON).Methods Bone tissues were selected from patients with steroid-induced ON between the necrotic zone of femoral heads and its femoral neck to analyze the miRNA expression profile using the microarray. The most differentially expressed miR-125a-3p and miR-1 7-5p in microarray analysis were further confirmed by real-time quantitative PCR.Results According to the microarray screening,8 miRNAs were upregulated and 3 miRNAs were downregulated in the necrotic zone of femoral heads samples (Fold>2,P <0.05 ).Results of real-time PCR revealed that miR-125a-3p was upregulated and miR-1 7-5p was downregulated in the necrotic zone of femoral heads samples,which were in agreement with the microarray data.Conclusion MiRNA’s differential expression profile of human steroid-induced ON samples was obtained.Among the differentially expressed miRNAs, miR-125a-3p and miR-1 7-5p are the most apparently differentially expressed miRNAs,which may be related to the pathogenesis and development of steroid-induced ON.
