Objective To verify the linear range of WBC measured by CD3700 hematocyte counter. Methods The high-valued specimen was prepared with the enriched white coat,and diluted as a series of concentrations of specimens with the physiological saline. Every specimen was measured for twice,and the sequence of specimens was random. And the Grubbsper test, polynomial regression anal-ysis,and random error estimation were performed. Results There is no outlier in the test results. Re-gression analysis showed it displayed linear in the range of 0 to 219 × 109/L,and the random error was within the allowable limit of our laboratory. Conclusion The linear range of WBC measured by CD3700 hematoeyte counter is coincident to what the manufacturer claims.

Objective To certify the linear range of WBC measured by CD3700.Methods Use the white stratum of blood after centrifugation.Then,the high value specimens were diluted with saline to get a series of samples with different concentrations.Every specimen was measured twice in order to keep the sequence of specimens randomly.The perform outlier test,polynomial regression analysis,and the random error estimation were carried out.Results There was no outlier in the results.It was demonstrated by polynomial regression to be linear from(0～219)?109 L-1.The random error was within the allowable limit of 1/4CLIA'88(3.75%).Conclusion The linear range of WBC measured by CD3700 is just like that of the manufacturer claims.

Lymphatic leakage and lymphatic cysts are common complications after radical resection of middle- and high-risk prostate cancer. There are many treatment methods but the effect is not accurate. This article reports two patients who were diagnosed by lipiodol lymphangiography under ultrasound guidance and used a mixture of n-butyl cyanoacrylate and lipiodol to embolize lymphatic leakage. Among them, one patient achieved success after one session of interventional embolization. Another patient achieved success after 3 interventions and embolization. Two patients had no complications related to lymphatic interventional therapy, and no lymphatic leakage recurred during the 3-month follow-up. Ultrasound-guided lymphangiography and lymphatic embolization through the inguinal lymph nodes are a feasible option for the treatment of refractory lymphoma leakage
