Hipbone Biomechanical Finite Element Analysis and Clinical Study after the Resection of Ischiopubic Tumors

Objective To investigate the changes of hipbone biomechanics after the resection of ischiopubic tumors and their relationships with the complications in the convalescent stage, and directing the postoperative pelvic reconstruction. Methods DICOM data were used to create an intact hipbone finite element model and postoperative model. The biomechanical indices on the same region in the two models under the same boundary condition were compared. The differences of displacement, stress, and strain of the two models were analyzed with statistical methods. Results The distribution areas of the hipbone nodes' displacement, stress, and strain were similar before and after the simulated operation. The sacroiliac joint nodes' displacement (P=0.040) and strain (P=0.000), and the acetabular roof nodes' stress (P=0.000) and strain (P=0.005) of two models had significant differences, respectively. But the sacroiliac joint nodes' stress (P=0.076) and the greater sciatic notch nodes' stress (P=0.825) and strain (P=0.506) did not have significant differences. Conclusions The resection of ischiopubic tumors mainly affect the biomechanical states of the homolateral sacroiliac joint and acetabular roof. The complications in the convalescent stage are due to the biomechanical changes of the sacroiliac joint and the acetabular roof and disappearances of the stabilization and connection functions of the pubic symphysis and superior ramus of pubis.

Observation on Therapeutic Effect in Treatment of Prostate Hyperplasia by Needle-warming Moxibustion

With Shenshu （BL 23）, Ciliao （BL 32）, Pangguangshu （BL 28）, Huiyin （CV 1） and Zhibian （BL 54） as the main acupoints, and with Sanyinjiao （SP 6）, Zhongji （CV 3） and Guanyuan （CV 4） as the combined acupoints, 51 cases of the patients sick with prostatic hypertrophy were treated by acupuncture, together with 47 cases treated with oral administration of Terazosin Hydrochloride Tablets as the control group. The total effective rate was respectively 88.2% and 70.2% in the two groups, better in the former than in the latter （P〈 0.05）.

Co-Infection of Chlamydia trachomatis and Neisseria gonorrhoeae on Adult Conjunctivitis:A Case Report

Introduction Chlamydia trachomatis(CT)and Neisseria gonorrhoeae(NG)infections are the most prevalent sexually transmitted infections among adults globally,1 and most commonly cause urogenital infections but also ocular infections,which often occur in newborns but rarely in adults.We herein report such a case of adult conjunctivitis caused by CT and NG coinfection.
