The risk areas where non-point source pollution may occur were compartmentalized and assessed, and the total soil erosion and the runoffs of N and P with rainfall in this valley were worked out by experiment and GIS mapping. The study indicated that the main type of soil erosion was moderate (erosion modulus is 1000-2500t/(km(2).a)) at present, and the intense erosion areas are located in dry land with variable slope east of the lake and the middle-south parts of steep slope mountainous region (erosion modulus is more than 5000t/(km(2).a)). Though the area is small, it should be paid attention to. The trend of non-point source pollution (NSP) of nitrogen and phosphorus loss was corresponded with the soil erosion. Spatial distribution and the reasons of the distribution difference have been presented and it was emphasized that the human activities among the influence factors was the most important. It surely offers a scientific basis to control and prevent non-point source pollution in the watershed.展开更多
目的:探讨耳聋左慈丸联合通气散加减味治疗慢性分泌性中耳炎(CSOM)肝肾阴虚证的疗效以及对血清水通道蛋白(AQP)^(-1)和AQP-4水平的影响。方法:慢性中耳炎患者共117例,参照数字表法随机分为治疗组58例和对照组59例;对照组给予盐酸头孢美...目的:探讨耳聋左慈丸联合通气散加减味治疗慢性分泌性中耳炎(CSOM)肝肾阴虚证的疗效以及对血清水通道蛋白(AQP)^(-1)和AQP-4水平的影响。方法:慢性中耳炎患者共117例,参照数字表法随机分为治疗组58例和对照组59例;对照组给予盐酸头孢美特酯分散片治疗,500 mg/次,2次/d;枸地氯雷他定片,1片/次,1次/d;噻洛唑啉鼻腔滴鼻剂,2滴/次,2次/d。治疗组在对照组治疗的基础上给予耳聋左慈丸联合通气散加减治疗,1剂/d,常规水煎煮,分早晚2次内服;两组患者均给予4周治疗。比较两组中医症状积分和各频率下的骨导阈值;检测两组患者血清AQP^(-1)和AQP-4水平。结果:治疗组治疗后中医临床症状积分均明显低于对照组(P<0.01);治疗组患者临床总有效率为89.61%,对照组为76.92%,治疗组总有效率高于对照组(P<0.05);治疗组治疗后各频率(1,2,4,8 k Hz)骨导阈值均明显低于对照组(P<0.01);治疗后治疗组血清AQP^(-1)和AQP-4水平均明显高于对照组,比较差异均有统计学意义(P<0.01)。结论:耳聋左慈丸联合通气散加减治疗CSOM肝肾阴虚证可明显改善患者临床症状,降低骨导阈值,上调血清AQP^(-1)和AQP-4水平。展开更多
目的探究耳聋胶囊联合天麻素注射液治疗突发性耳聋的临床疗效。方法选取2016年1月—2017年1月陕西省核工业二一五医院耳鼻咽喉科收治的突发性耳聋患者161例为研究对象,所有患者随机分为对照组(80例)和治疗组(81例)。对照组肌内注射天麻...目的探究耳聋胶囊联合天麻素注射液治疗突发性耳聋的临床疗效。方法选取2016年1月—2017年1月陕西省核工业二一五医院耳鼻咽喉科收治的突发性耳聋患者161例为研究对象,所有患者随机分为对照组(80例)和治疗组(81例)。对照组肌内注射天麻素注射液,2 m L/次,1次/d。治疗组在对照组的基础上口服耳聋胶囊,3粒/次,2次/d。两组患者均治疗4周。观察两组的临床疗效,比较两组的言语频率平均听阈、症状消失时间和听力损失情况。结果治疗后,对照组和治疗组的总有效率分别为85.00%、97.53%,两组比较差异有统计学意义(P<0.05)。治疗后,两组言语频率平均听阈均显著降低,同组治疗前后比较差异有统计学意义(P<0.05);且治疗组言语频率平均听阈明显低于对照组,两组比较差异具有统计学意义(P<0.05)。治疗后,治疗组呕吐、头晕、耳鸣消失时间明显短于对照组,两组比较差异有统计学意义(P<0.05)。治疗后,两组轻度听力损失患者明显增加,中重度、重度和极重度患者明显降低,同组治疗前后比较差异有统计学意义(P<0.05);且治疗组中重度、重度和极重度患者明显低于对照组,两组比较差异具有统计学意义(P<0.05)。结论耳聋胶囊联合天麻素注射液治疗突发性耳聋具有显著的临床疗效,能够改善患者的听力损失程度,缩短临床症状消失时间,安全性较好,具有一定的临床推广应用价值。展开更多
