Preliminary Evaluation on Resources Enhancement of Artificial Reef in the East Corner of Zhelang Shanwei

In order to analyze the improvement of fish resource,the trawl net and gill net were used in the background survey and investigation in the artificial reef area and control area of the east of corner was discussed in Zhelang Shanwei in January 2003 and April 2010 respectively.Margalef species richness index,Shannon-Winener diversity index and Pileou uniformity index were chosen to analyze the multiformity of biological population and community structure.Resource density index of trawl net investigation and catch rate of gill net were chosen to estimate the variance of biomass.The results of the trawl net showed that the resources density of the artificial area increased by 3.078 times,and numbers of species increased by 1.875 times,squilla being the dominant group instead of the fish,and the first dominant species being squilla oratoria(Oratosquilla oratoria),which increased by 4.372 times before the artificial reef dropped.The results of the gill net showed that the catch rate of the artificial area increased by 12.043 times,numbers of species increased by 1.333 times,the dominant group was fish,it increased greatly,the first dominant species was golden small fish(Sardinella aurita),which increased by 13.035 times before the artificial reef dropped.Both the results of trawl net and gill net indicated that the effect of fish assemblage were evident,and the community structure had improved greatly.It showed a wonderful effect on conservation and assemblage of fishes resource.The artificial reefs developed a new resource enhancement system in the east corner of Zhelang Shanwei accomplished basically.

The Study of Urban Planning Decision-Making in the Background of Rapid Economic Development —— A Case Study of Shanwei City

Urban planning decision-making is an activity for the decision-makers to collect information, judge function of cities, select project and make policy which is ainaed at the problem of urban planning that have taken place, is taking place and will take place. Using historical review and comparative analysis, the articles summarizes planning decision-makings of Shanwei city and it＇s problem, and makes some suggestions to urban planning decision-making system of Shanwei city in the new period.

善胃Ⅰ号方对血瘀热毒型胃粘膜异型增生p21蛋白的影响

[目的]观察中药善胃I号方对慢性萎缩性胃炎(CAG)胃粘膜异型增生的治疗效果 ,并观察ras癌基因蛋白p21在治疗前后的表达情况。[方法]将内镜和病理确诊为CAG胃粘膜异型增生的患者且符合中医血瘀热毒证型82例 ,随机分为治疗组和对照组。治疗组34例 ,予善胃Ⅰ号方 ;对照组48例 ,予市售猴头菌片 ,两组均用药12周。[结果]1)治疗组患者治疗前后症状缓解总有效率为81 % ;对照组患者治疗前后症状缓解总有效率为44.74 % ,P<0.005 ;2)病理改变 :中药治疗后多数患者病理改善 ,粘膜萎缩消失8例 ,转为轻度12例 ,重度转为中度7例 ,无变化6例 ,加重1例 ;而对照组消失2例 ,转为轻度4例 ,转为中度5例 ,无变化33例 ,加重4例 ,中药组明显优于对照组 ,P<0.005 ;3)中药治疗组治疗前后 p21蛋白表达阳性指数下降较对照组更为明显 ,两者有显着性差异 (P<0.05)。[结论]中药善胃Ⅰ号方对萎缩性胃炎有良好的治疗作用 。

善胃Ⅰ号方对胃癌前病变大鼠胃粘膜NHE1蛋白及胃内pH值的影响

目的:通过观察善胃Ⅰ号方对胃癌前病变模型大鼠胃粘膜NHE1蛋白及胃内pH值的影响,从胃内环境角度,探讨该方干预胃癌前病变的作用机制。方法:将80只健康Wistar大鼠随机分为4组,即正常对照组、模型对照组、阳性药物组和善胃Ⅰ号方组,每组20只,造模24周后开始给予药物干预,给药6周后,采用免疫组化法检测大鼠胃粘膜NHE1蛋白的表达水平,高精度酸度计测定大鼠胃液pH值的变化。结果:善胃Ⅰ号方组NHE1蛋白的阳性表达率及胃液pH值较模型对照组及阳性药物组均明显降低(P<0.05)。结论:善胃I号方可能通过抑制胃癌前病变模型大鼠胃粘膜NHE1蛋白的表达,降低胃液pH值,有效维持胃内酸性环境,从而起到干预胃癌前病变发展的作用。
