Methods The SpaA was purified by electroelution from NaOH-extracted antigen of Erysipelothrix rhusiopathiae strain C43311. The rSpaA-N was expressed in E. coli BL21 as a soluble protein by IPTG inducing,and purified with GST affinity chromatography. Mice of each group were subcutaneously immunized three times with 50μg or 100 μg of native SpaA, rSpaA-N or NaOH-extracted antigen with in complete or incomplete Freund adjuvant at 2-week intervals.

将猪丹毒丝菌C43311株SpaA-N以可溶形式表达在大肠杆菌BL21中，用GST Bind Resin纯化试剂盒纯化rSpaA-N，采用电洗脱法从猪丹毒丝菌C43311株NaOH提取抗原中纯化天然SpaA，将rSpaA-N、天然SpaA和NaOH提取抗原制成亚单位疫苗，同时设GST及生理盐水对照组，间隔2周分3次皮下免疫小鼠，第3次免疫后2周用100LD50猪丹毒丝菌C43065株进行腹腔攻毒，采用间接ELISA方法检测免疫组小鼠血清的抗体动态变化。

The HPV positivity amongst the group of women with no cervical abnormality was 43%, while that in women with cervical dysplasia and cervical cancer was 81.2% PCR products from 89 HPV positive cases were genotyped by LiPA, of which 49 cases were single HPV infected concerning 11 different HPV types and the commonest type was HPV-16, occurring in 25(51%) of all single HPV infected cases. The other 40 specimens contained multiple HPV types comprising 16 different HPV types. Although double infections(n=25) prevailed, triple(n=9),quadruple(n=3) and quintuple(n=3) infections were also found. PCR products of four HPV positive cases failed to be classified by LiPA. Sequencing analysis revealed that these 4 cases were HPV-66 which was not included in LiPA probes. Follow-up data of 12 cases confirmed the HPV genotyping results. Conclusion The LiPA for HPV genotyping is easy to perform.

结果 155例妇女子宫颈刮片中HPV DNA检出率为60%，其中在宫颈细胞学检查正常或仅有炎症病变的妇女中HPV DNA阳性率为43%，而在宫颈细胞增生不良或宫颈细胞癌的妇女其阳性率为81.2%。93例HPV阳性的标本中，89例利用LiPA成功地作出了基因分型，其中单独一型HPV感染为49例，涉及11种不同基因型HPV，最常见的型别为HPV 16，占单独感染的51%(25/49)；另40例为不同型别HPV重叠感染，涉及所有16种HPV基因型别，二重感染占主导地位(n=25)，同时也检测出其它多重感染。4例HPV阳性的标本应用LiPA未能作出基因分型，DNA序列分析显示这4例为HPV 66感染，此型别不包括在LiPA所标记的探针内。12例随诊资料显示了LiPA的物异性及高度的重复性。

METHODS: Dogs (n=16) were randomly divided into 2 groups: the control (n=7) and the CHF group (n=9) induced by rapid right ventricular pacing at 240 pulsemin^(-1) for 4 to 5 weeks.

The results indicate that the high efficiency and stable performance of shortcut nitrogen removal in MBR-PBBR process is attributed to the predominance of functional microbiology Nitrosomonas eutropha during the period of operation,which occupies over 54%of total bacteria.However,large amount of organic carbon can destroy the predominance of N.eutropha,whose proportion decreased to 31%at TOC/N=0.3.The diversity of microbial community in MBR increases along with operating time.

结果发现，生物强化的MBR-PBBR工艺能实现相对稳定和高效的捷径生物脱氮，主要归功于MBR中的功能微生物Nitrosomonas eutropha在运行过程中始终保持优势地位，占全菌数的比例大于54%；然而，当外加有机碳源较高(TOC/N≥0.2)时，可动摇氨氧化菌的优势地位，N.europha占全菌数的比例在TOC/N=0.3时下降至31%。

An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.

2Soil column leachate experiment shows, soil texture and soil section form are the main factors affecting the nitrate leaching; in soil organic fertilizer produce a nitrate leaching process, during five-month experiment, nitrate content has be increasing in leakage solution, organic fertilizer applying decrease the pH and increase the electric conduction of leakage solution, there is positive action between nitrate content in leakage solution and electric conduction, which shows that nitrate-N accumulation during organic fertilizer applying is one of the main factors for soil salification; for decrease the leaching of the nitrate-N in soil, in sandy moisture soil the best amount of organic fertilizer should be 7.5～ 15 t·hm~(-2), in Loamy moisture
