ABSTRACT
Objective To investigate the clinical value of glycosylated hemoglobin(HbA1c),glycosylated serum protein(GSP),sex hormone binding globulin(SHBG),three acylglycerol(TG),free fatty acid(FFA)in diagnosing gestational diabetes mellitus(GDM).Methods 103 cases of GDM patients and 98 cases of healthy pregnant women from February 2015 to August 2016 were selected as the GDM group and control group.The positive detection rates and levels of HbA1c,GSP,SHBG,TG and FFA were compared between the two groups.Moreover the diagnostic efficiency of various indicators was analyzed.Results The levels of HbA1c, GSP,TG and FFA in the GDM group were significantly higher than those in the control group,while the SH-BG level was significantly lower than that in the control group,the difference was statistically significant(P<0.05);the positive rates of HbA1c,GSP,SHBG,TG and FFA in the GDM group were significantly higher than those in the control group,the difference was statistically significant(P<0.05);the specificity,sensitivity and positive prediction value of HbA1c,GSP,SHBG,TG and FFA for jointly diagnosing GDM were signifi-cantly higher than those of single indicator,the difference was statistically significant(P<0.05).Conclusion Detecting HbA1c,NGSP,SHBG,TG and FFA is more accurate for jointly diagnosing GDM,has an important diagnostic value,and can serve as the assisted diagnostic indicators.
ABSTRACT
Objective To identify the species of sarcosaphagous flies by amplifying cytochrome oxidase subunitI (CO I) gene fragment,combined with morphological characteristics.Methods The DNA of sarcosaphagous flies was extacted by modified Tris balanced phenol-Tris saturated phenol protocol,the amplificationand sequencing of CO Ⅰ fragment were conducted,and the results were then compared with the database for analysis.Results The modified DNA extration method by Tris balanced phenol-Tris saturated phenol could obtain effective DNA of sarcosaphagous flies,and be applied for CO Ⅰ fragment amplification,and thus for identification of the species of sarcosaphagous flies.Conclusion The DNA extracted from sarcosaphagous flies by modified Tris balanced phenol-Tris saturated phenol protocol could be used astemplate for the amplification of CO Ⅰ fragment,and the system could identify the species of sareosaphagous flies after sequencing and alignment with the sequences of database.Compared with traditional identification methods of using morphological characteristics,the current system is more accurate and could be more widely applied.
ABSTRACT
OBJECTIVE:To evaluate the stability of cefoxitin sodium for injection compatible with metronidazole injection fluid.METHODS:Cefoxitin sodium for injection was compatible with metronidazole injection fluid and the solution was stored ordinary temperature for4hours,the maximum absorption peak and absorbance of the solution were determined by UV,and the color of the solution was observed,and its pH value was determined.RESULTS:There were no significant changes in absorp-tion peak,absorbance,color and pH value of the compatible solution.CONCLUSION:Cefoxitin sodium for injection is com-patible with metronidazole injection fluid,and the compatible solution remains stable at ordinary temperature for4hours.
