Sexual behavior characteristics and influencing factors of gonorrhea patients in Yunnan Province / 中华疾病控制杂志

Objective To investigate the sexual behavior types, condom use and influencing factors of gonorrhea patients in Yunnan Province, and to provide evidence for the adjustment of sexually transmitted disease (STD) prevention and control strategy. Methods A cross-sectional study was carried out to investigate gonorrhea patients in 14 STD clinics in 7 more prevalent prefectures (cities) of Yunnan Province. A questionnaire survey was conducted to investigate the socio-demographic and sexual characteristics of the patients in a one-to-one way. Multiple Logistic regression model was used to analyze the influencing factors of sexual behavior. Results A total of 179 cases of gonorrhea were investigated. The average age was (29.01±8.93) years old. 95.53% (171/179) patients were 40 years old and 88.27% were male patients (158/179). Unmarried patients accounted for 55.31% (99/179). Service and self-employed patients accounted for 34.64% (62/179) and 23.46% (42/179) respectively. The rate of sexual intercourse with opposite sex was 98.32% (176/179), the rate of men who have sex with men was 1.68% (3/179) and the rate of having more than two sexual partners was 27.93% (50/179). The rate of sexual intercourse between temporary partners, spouses/fixed partners and commercial partners were 53.07% (95/179), 37.99% (68/179) and 8.94% (16/179) respectively. Recent sexual activity had lower condom use rate, 17.89% (17/95), 19.12% (13/68) and 18.75% (3/16) respectively. The main ways for gonorrhea patients to make temporary partners were friend introductions or gatherings, accounting for 66.32% (63/95). Condom use in male patients was worse than that in female patients (OR=0.234, 95% CI: 0.084-0.656, P=0.006). Conclusions The patients with gonorrhea were mainly unmarried young adults. The main risk behaviors were unprotected behaviors between heterosexual temporary and spouse/fixed sexual partners. The condom use consciousness was generally low. The promotion of safe sex education for young adults should be further strengthened, with special attention to the use of condoms for temporary sexual behavior and spouse/fixed sexual intercourse.

Effects of buried penis on the structure and function of corpus cavernosum in a rat model / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>While the abnormal appearance of the concealed penis has been well recognized, the effect of buried penis on the structure and function of corpus cavernosum has not been well studied. To explore this issue, we established a rat model and evaluated the effect of buried penis on cavernosum weight, contents and ultrastructure of tissue, and nitric oxide synthase (NOS) activity.</p><p><b>METHODS</b>Two hundred and ten rats were randomly divided into 3 equal cohorts for 2, 4 and 6 months study (groups A, B and C). Each group was randomly divided into buried group (n = 40), control group (n = 15), and normal group (n = 15), respectively. Intra-purse-string suture of the root of the penis was used to establish the model. Macroscopic development was judged by measuring the weight of the corpus cavernosum. Masson's trichrome staining was performed for observing microstructure while a transmission electron microscope was used for observing ultrastructure. The NOS activity was detected by a NOS activity assay kit.</p><p><b>RESULTS</b>Buried penis had no significant influence on the appearance and weight of the corpus cavernosum. Buried penis resulted in decreased smooth muscle content (P > 0.05 in group A, and P < 0.05 in groups B and C) and increased fibrous connective tissue content (P > 0.05 in groups A and B, and P < 0.05 in group C) compared with the normal and control groups. Ultrastructural abnormalities of corpus cavernosum were observed in the 6-month buried group. Moreover, there was decrease of NOS activity in groups B and C (P < 0.05 in group B and P < 0.01 in group C) when compared with the normal and control groups.</p><p><b>CONCLUSION</b>Buried penis affects the structure and function of corpus cavernosum in rats and the effect is positively correlated with the buried time, but there is no significant effect on the macroscopic development.</p>

Concealed penis affects the morphology of the corpus cavernosum in rats / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the influence of concealed penis on the morphology of the corpus cavernosum in rats.</p><p><b>METHODS</b>Rat models of concealed penis were established by intra-pocket-suture of the root of the penis. Fifty rats were equally assigned to Groups A (2-month) and B (4-month), each further divided into a buried (n = 15) and a normal subgroup (n = 10). Changes in the morphology of the penile cavernous tissue were observed under the light microscope and transmission electron microscope.</p><p><b>RESULTS</b>Compared with Group A, Group B showed significant ultra-structural pathological changes in the corpus cavernosum, including abnormal arrangement of endothelial and smooth muscle cells, massive hyperplasia of interstitial tissues, narrowed cavernous sinus, atrophic smooth muscle cells, degenerated mitochondria, dilated endoplasmic reticula, decreased dense bodies and contractile fibers, and cytoplasmic vacuolization. No significant differences were found in the appearance and weight of the corpus cavernosum between the buried and normal groups (P > 0.05).</p><p><b>CONCLUSION</b>Concealed penis does not significantly affect the appearance and weight of the corpus cavernosum, but causes ultra-structural pathological changes in it with the lengthening of time.</p>

The damage to the ultrastructure of seminiferous tubules was aggravated with the prolonging of varicocele.</p><p><b>CONCLUSION</b>EV can cause a progressive decline of ITC, dyszoospermia and increased AI of germ cells.</p>

Two ways of constructing concealed penis model in rats: a comparative and analytical study / 中华男科学杂志

<p><b>OBJECTIVE</b>To establish a stable rat experimental model of concealed penis for studying the effect of buried penis on the structure and function of the corpus cavernosum.</p><p><b>METHODS</b>Ninety male SD rats, aged 2 weeks, were randomly divided into 3 groups (A, B and C) of equal number. Groups A and B underwent surgery with intra-purse suture of the penile root and folding suture of the prepuce, respectively, to bury the penis, while Group C were included as sham operation controls.</p><p><b>RESULTS</b>In Group A, death resulted in 4 cases from acute post-operative urine retention, failure in burying the penis occurred in 5 cases because of soft tissue ulceration around the urethral orifice and in another 3 due to loose concealment. In Group B, 1 died from deep anesthesia and 2 from acute post-operative urine retention. With the penile development and erection, 7 in Group A and 10 in Group B protruded the penis in different stages. In Group C, 1 died from deep anesthesia. The operations succeeded in all the other rats in Groups A and B, with the success rates of 36.7% and 56.7%, respectively. And the concealment could be relieved any time during the experiment.</p><p><b>CONCLUSION</b>The experimental rat model of concealed penis can be successfully established by both intra-purse suture of the penile root and folding suture of the prepuce, which is stable and similar to the natural course of this disorder in human.</p>

Hydrogenation properties of mechanically milled Mg2Ni0.8Cr0.2-CoO/Al2O3 composites / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Mg2Ni0.8Cr0.2-x wt.% CoO/Al2O3 (x=0.5, 1, 2 and 3) composites were prepared by mechanically milling sintered Mg2Ni0.8Cr0.2 alloy and CoO/Al2O3 compound for 45 h. The addition of CoO/Al2O3 compound resulted in the good kinetics properties of hydriding/dehydriding reaction of the composites. The composite with 1.0 wt.% CoO/Al2O3 catalyst could reach the maximum hydrogen absorption capacity (2.9 wt.%) within 5 min at 393 K under H2 pressure of 4 MPa, and can desorb rapidly at 493 K. The decomposition and synthesis of hydrogen molecule on Mg2Ni0.8Cr0.2 alloy surface was promoted by addition of CoO/Al2O3 catalyst. In addition, the formation of metallic Ni particles, strain and defects during the ball milling process also resulted in the improved hydrogenation performance of Mg2Ni-based alloys.

Influence of estradiol benzoate on the testis development of rats / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the influence of estradiol benzoate (E2B) on the testis development of Sprague-Dawley (SD) rats.</p><p><b>METHODS</b>Newborn male SD rats were injected subcutaneously with E2B (0.2 mg/5 g body weight). At days 14, 21, 28, 42 and 56 after birth, the rats were sacrificed after anaesthesia, and their testes were taken out and weighed. The cranial and caudal SEH and TD were measured respectively, the TD/SEH ratio in each part of the testis and the caudal SEH/cranial SEH ratio were calculated, and different stages of spermatogenesis were analysed.</p><p><b>RESULTS</b>In the experimental group, the testis weight was significantly lower than that of the control (P < 0.01), the testes constantly remained in the abdominal cavity, and there was much fluid retention in the rete testis all the time. From day 21 on, the TD/SEH ratio in the cranial testis was much higher than in the control (P < 0.01), and so was the caudal SEH/cranial SEH ratio (P < 0.01). And spermatogenesis was obviously retarded as compared with the control (P < 0.01).</p><p><b>CONCLUSION</b>Exposure of newborn male SD rats to E2B can cause fluid retention in the testis and cryptorchid, which in turn may retard spermatogenesis.</p>

Expression and significance of PCNA and p27 in benign prostate hypertrophy and prostate carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the expression of PCNA and p27 in human benign prostate hypertrophy (BPH) and prostate carcinoma (PCa) and their effect on the genesis and progression of the tumor.</p><p><b>METHODS</b>The paraffin-embedded sections of 30 cases with BPH and 37 cases with PCa were collected. The expression of p27 and PCNA protein were examined by S-P immunohistochemical method. Comparative analysis for BPH and pathological grade and clinical stage of PCa was performed.</p><p><b>RESULTS</b>The expression of PCNA in BPH (3.3%) was significantly lower than that in Pca (83.8%, P < 0.01). The expression of p27 in BPH (70.0%) was significantly higher than that in Pca (27.0%, P < 0.05). The expression of p27 was not correlated with histological grade and clinical stage in Pca (P > 0.05). An inverse correlation was found between p27 and PCNA expression in BPH (P < 0.01), while no correlation was found in Pca (P > 0.05).</p><p><b>CONCLUSION</b>The loss or decreased expression of p27 protein may be related to the genesis of benign prostate hypertrophy, but not to the development of prostate carcinoma; the overexpression of PCNA may play an important role in the malignant behavior and progression of prostate carcinoma.</p>

Effects of veratryl alcohol and tween 80 on ligninase production and its roles in decolorization of azo dyes by white-rot basidiomycete PM2 / 生物工程学报

Basidiomycete PM2, a lignin-degrading white rot fungus, produces lgnin peroxidase (Lip) and manganese peroxidase (Mnp) in nutrient nitrogen limited liquid cultures. This fungus was selected for its ability to decolorize azo group of dyes. In order to improve production of the peroxidases and rapid dye decolorizing activity by basidiomycete PM2, the addition of veratryl alcohol or Tween 80 to nutrient nitrogen limited liquid cultures were tested. It was found to have a large stimulatory effect on Mnp activities and decolorization rate of azo dyes. A maximum Mnp activities of 254.2 u/L with veratryl alcohol and 192.2 u/L with Tween 80 were achieved respectively. These values were about 3.4-fold and 2.5-fold higher than that obtained in the control cultures (without alcohol or Tween 80), whereas the levels of Lip activity detected were very low (about 12 u/L)in all the cultures. In further experiments using three kinds of azo dyes of congo red, orange G and orange IV, enzyme activities and dye decolorization were investigated in the above-mentioned cultures. The results showed that Mnp activities and decolorization were notably higher than those obtained in the control cultures in the presence of azo dyes. Cultures supplemented with Tween 80 were more adequate for dye decolorization. The rates of the decolorization with Tween 80 of congo red (95.4%), orange G (98.5%) and orange IV (54.4%) after 24 hours of dye incubation were higher than that supplemented with veratryl alcohol. According to the results, Mnp activities secreted by basidiomycete PM2 play an essential role in the process of dye decolorization. Tween 80 was the main factor affecting the decolorization. The analysis of structure of the three kinds of azo dyes indicats that the extent of decolorization is affected by the dye molecular structure. The types and quantity of the substituted groups on the aromatic ring of azo dyes have effect on the percentage of biological decolorization.
