The spearman correlation coefficient was 0.308 (P＜0.01) between serum proinsulin and risk factors score, and the partial correlation coefficient was 0.2095 (P＜0.01) after adjustment for age, sex, body mass index and waist circumference. The results of non-conditional univariate Logistic regression and multivariate stepwise Logistic regression indicated that serum proinsulin level associated with cardiovascular risk factors aggregation, and the odds ratio (95％ CI) was 1.656 (1.483～1.851), 1.652 (1.475～1.850)(p＜0.01) respectively.

Spearman相关分析及调整年龄、性别、体重指数与腰围后的偏相关分析结果显示，胰岛素原水平与危险因素评分的相关系数分别为0.308与0.2095(P值均为0.000)；单因素及多因素Logistic回归分析显示，胰岛素原的水平与心血管危险因素聚集显著相关，其OR值(95％可信区间)分别为1.656(1.483～1.851)、1.652(1.475～1.850)(p＜0.01)。

Methods The method of replenishing qi to reinforce the spleen and dissolving phlegm to remove turbidity was used,and eight periumbilical points (Tianshu,Huaroumen,Wailing,Yinjiao and Shuifen),points Guanyuan and Zusanli were selected in cooperation with auricular-plaster therapy.In the corresponding period,30 healthy persons were selected for comparison.Changes in FBG,INS,ISI,TC,TG,LDL-C and HDL-C were evaluated after acupuncture in simple obesity patients.Also were changes in waist circumference,hip circumference,waist-to-hip ratio,body weight and BMI,and differences in them between the curative effects on degree Ⅰ and degree Ⅱ obesity.

方法采用&益气健脾，化痰消浊&法，取脐周八穴(天枢、滑肉门、外陵、阴交、水分)、关元、足三里等穴，配合耳穴贴压，并与同期30例健康体检者比较，观察针刺前后单纯性肥胖症患者FBG、INS、ISI、TC、TG、LDL-C、HDL-C的变化；还观察针刺前后单纯性肥胖症患者腰围、臀围、腰臀比、体重、BMI的变化，及其Ⅰ度肥胖、Ⅱ度肥胖的疗效差异。

Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。
