ABSTRACT
The concept of biometric identification technology (BIT)was described,and several typical BITs were introduced such as identification technologies for hand, face, physiological features and behavioral trait. The application of BIT was analyzed in military field of foreign countries and China.It's pointed out BIT's future involved in bioassay,integration with wireless video identification technique and etc,comprehensive identification technique with high throughput,high precision and multi mechanism as well as enhanced safety.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical effect of Devine's technique with free skin grafting in the treatment of concealed penis with prepuce deficit.</p><p><b>METHODS</b>This study included 7 children with concealed penis, aged 6 - 15 (mean 8.6) years, 6 of them treated by circumcision previously. All the patients underwent Devine's operation to resect the inelasticity sarcolemma and lengthen the penis. The length of prepuce deficit ranged from 2 to 4 cm. Intermediate split thickness skin grafts of the corresponding length were taken from the femoribus internus to wrap up the tunica albuginea penis, followed by the procedures of saturation, encapsulation and fixation.</p><p><b>RESULTS</b>Surgery time ranged from 70 to 120 minutes, averaging 90.5 minutes. The penis was prolonged about 2 - 4 cm after surgery. A 6-month follow-up revealed desirable penile appearance and normal penile erection.</p><p><b>CONCLUSION</b>Devine's technique with free skin grafting from the femoribus internus is an ideal treatment for concealed penis with prepuce deficit.</p>

<p><b>OBJECTIVE</b>To investigate the clinical and pathological features, diagnosis and treatment of cystic lymphangioma of the spermatic cord.</p><p><b>METHODS</b>One case of cystic lymphangioma of the spermatic cord in a 71-year-old patient was retrospectively analyzed and the relevant literature was reviewed.</p><p><b>RESULTS</b>The patient, presented with spermatic cord hydrocele, was treated by local excision of the tumor, which was pathologically diagnosed as cystic lymphangioma. No relapse was found during a 3-month follow-up after the operation.</p><p><b>CONCLUSION</b>Lymphangioma of the spermatic cord is a benign tumor. Preoperation ultrasonography and CT are important for determining the location and nature of lymphangioma. Surgical excision is an effective option for the treatment of cystic lymphangioma of the spermatic cord.</p>
