广东省的黑熊资源在历史上曾经广泛分布于全省各地,但在1999～2001年的调查显示广东省的黑熊资源仅分布在粤北的部分山地林区,而且数量在50～100只左右。栖息地的减少和大量的捕杀都对黑熊资源产生威胁。因此我们建议对全省的黑熊资源进行调查及监测,加强野生黑熊资源保护及规范黑熊饲养场的管理等。

水鹿是具很高经济价值的国家Ⅱ级重点保护动物,曾在广东省内广泛分布,但目前仅分布于粤北及粤东和粤西北部的部分地区。本文在介绍水鹿的基础上,综合多次野外调查,分析水鹿的分布状况,发现水鹿的资源有恢复的趋势,并提出保护广东省水鹿资源的合理化建议。

Objective: To explore the application value of indorquine green combined with methylene blue in sentinel lymph node identification for endometrial carcinoma. Methods: 93 cases of endometrial cancer patients admitted in our hospital from August 2016 to September 2017 were selected and divided into two groups by the random number table method. The methylene blue was used in the control group, indorquine green and methylene blue were used in the observation group. The sentinel lymph node excision time,intraoperative blood loss, number of lymph node excision, number of cases of para-aortic lymph node resection, sentinel lymph node identification rate were compared between two groups. And the accuracy, sensitivity and specificity of the two methods were also compared. All the patients were followed-up for 12 months, the relapse and incidence of related complications were compared between two groups. Results: There was no statistically significant difference in the sentinel node resection time, intraoperative blood loss, number of lymph node resection and number of para-aortic lymph node resection cases between the two groups(P>0.05). The success rate of sentinel node recognition, accuracy and specificity of the observation group was significantly higher than that of the control group(P<0.05), and there was no statistical difference in the sensitivity and recurrence rate between the two groups(P>0.05). No adverse reactions such as skin necrosis, allergy or permanent staining occurred in either group during the follow-up period. Conclusion: The application value of indoturnip-green combined with methylene blue in the identification of sentinel lymph nodes in endometrial cancer is significantly higher than that of methylene blue alone.

In order to simplify the steps of detection soil field heavy metal and improve the precision of the equipment, using LabVIEW we wrote control program for the steady speed magnetic stirring module and automatically adding module and put them into the developed 16-bit high precision electrochemical analysis module of heavy metals ( LabCHEM- 10M). The system realized the function of on-line integrated detection by the control of upper machine, used stepper motor assembly into steady speed magnetic stirring device. It guaranteed the stability of stirring speed. The automatically adding device used 5 mL and 100 mL trace syringes for automatic filling buffer and standard solution,it could improve the accuracy of sample and simplify the operation process. The linear scanning results of Cd, Pb,Bi ions proved the experimental consistency was good. The test linear correlation could reach 0. 999 7 of cadmium in rice sample tests,and the test results met the requirements of general field test stability and accuracy. The results showed that the system is convenient and reliable operation. Moreover,it has advantages of convenient and reliable operation,friendly interface, rapid low cost analysis and monitor.
