RESUMEN
Melioidosis is an infectious disease caused by Burkholderia pseudomallei.Its clinical manifestations are diverse,often recurring and accompanied by sepsis,and it is prone to misdiagnosis and mistreatment,resulting in a high mortality.This paper analyzes a case of melioidosis sepsis combined with hemophagocytic syndrome,and fur-ther summarizes the clinical characteristics,diagnosis and treatment of the disease based on domestic and foreign li-teratures,so as to reduce misdiagnosis and mistreatment of the disease and improve survival rate of patient.
RESUMEN
Specimens of the genus Micrencaustes deposited in Bernice P. Bishop Museum were studied. Two new species Micrencaustes (Mimencaustes) rotundimaculata sp. n. and Micrencaustes (Mimencaustes) serratimaculata sp. n. are described and illustrated. A key to worldwide species of the subgenus Mimencaustes is provided.
RESUMEN
<p><b>BACKGROUND</b>Based on our clinical experience, the number of dorsal penile nerves in patients with primary premature ejaculation (PPE) is not consistent with the average number (2 branches). In this study, we evaluated the number and distribution of dorsal penile nerves among healthy Chinese adults and patients with PPE.</p><p><b>METHODS</b>The dorsal nerve of the penis, the deep dorsal vein of the penis, and the dorsal artery of the penis between the deep fascia of the penis and the albuginea penis were carefully educed, observed, and counted in 38 adult autopsy specimens. The number and distribution of the dorsal penile nerve in 128 surgical patients with PPE were determined.</p><p><b>RESULTS</b>The numbers of dorsal penile nerves of the 38 cases were as follows: 7 branches in 1 case; 6 branches in 1 case; 5 branches in 6 cases; 4 branches in 9 cases; 3 branches in 14 cases; and 2 branches in 7 cases. Most of the dorsal nerves were parallel to each other and in the dorsum of the penis. In only 8 cases, the branches were connected by some communicating branches. In 4 cases, 1 or 2 thin dorsal nerves continued their pathway over the ventral aspect of the penis. The average number of branches of the dorsal penile nerve in patients with PPE was 7.16.</p><p><b>CONCLUSIONS</b>Based on the study of 38 cases, the average number of dorsal penile nerves was 3.55 branches and that of patients with PPE was greater. These preliminary results suggest that the excessive dorsal penile nerves may have an impact on PPE via increased sensitivity and provide topographic data for the possible treatment of PPE.</p>

<p><b>OBJECTIVE</b>To investigate the effects of 4OH-Tamoxifen (OHT) on proliferation and apoptosis of primary cultured prostate stromal cells.</p><p><b>METHODS</b>Primarily cultured prostate stromal cells in vitro were treated with various concentrations (10(-8) mol/L - 10(-5) mol/L) of estradiol (E2), diethylstilbestrol (DES), OHT and the mixture of E2 (10(-8) mol/L - 10(-6) mol/L) with OHT (10(-7) mol/L) and then MTT and TUNEL were used to detect their proliferation and apoptosis respectively.</p><p><b>RESULTS</b>There was a significant difference (P < 0.05) between OHT and estrogens in the effects on the apoptosis and proliferation of the primarily cultured prostate stromal cells. OHT suppressed proliferation of the prostate stromal cells at the concentrations from 10(-7) mol/L to 10(-5) mol/L (P < 0.05), and this effect was concentration related (r = -0.383, P = 0.005); OHT (10(-7) mol/L) suppressed the proliferation stimulation effect of E2 at the concentrations from 10(-8) mol/L to 10(-6) mol/L (P < 0.05). OHT induced apoptosis at the concentrations from 10(-8) mol/L to 10(-5) mol/L (P < 0.05), and this effect was concentration related (r = 0.349, P = 0.012). The apoptosis induced by OHT could not be reversed by E2 at the concentrations from 10(-8) mol/L to 10(-5) mol/L (P > 0.05).</p><p><b>CONCLUSION</b>OHT can obviously suppressed the proliferation and promote the apoptosis of primarily cultured prostate stromal cells, which might not be totally attributed to the competitive inhibition of the estrogen receptor.</p>
