Multiple factors logistic regression analysis on the basic syndromes related factors in patients with chronic prostatitis / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the basic syndrome related factors in patients with chronic prostatitis (CP).</p><p><b>METHODS</b>Using questionnaire to collect data of CP patients from three hospitals in Beijing, Epidata 3.02 to establish database, the uni-variate and multiple Logistic regression analysis was performed with SPSS 17.0 software to determine the basic syndrome related factors.</p><p><b>RESULTS</b>Engagement in brainwork was the main risk factor for suffering from dampness-heat downward-flow syndrome; CP of type IIIA (classified by Western medicine), employed on brainwork or physical work, and working time < or =8 h were risk factors for suffering from qi-stagnancy and blood-stasis syndrome; illness duration >12 months, uncomfortable habitat, dislike for irritative beverages and poor digestive function were risk factors for Gan-qi stagnation syndrome; and aging, decreased burden from work, winter onset of the illness were those for Shen-yang deficiency syndrome.</p><p><b>CONCLUSIONS</b>The basic syndrome related factors in patients with CP are age of patient, duration and type of illness, occupational type, daily working time, burden from work, onset season of illness, living amenity, state of digestion, and relish for irritative beverage.</p>

Alternating magnetic field damages the reproductive function of murine testes / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the relationship between physical and biological effects of alternating magnetic field and study the influence of the magnetic field on the reproductive function of murine testes.</p><p><b>METHODS</b>Thirty ICR mice were randomized into 5 groups: normal control, X-ray radiation, weak magnetic field (1000 Hz), 1 h strong magnetic field and 2 h strong magnetic field (2000 Hz). The mice were sacrificed at 7 days after the exposure for the analysis of testicular sperm motility, observation of histopathological changes in the testis by HE staining and evaluation of the changes by modified Johnsen grade criteria.</p><p><b>RESULTS</b>The rates of sperm motility were (42.37 +/- 10.24)% in the normal control group, (39.00 +/- 12.35)% in the X-ray radiation group, (36.00 +/- 17.28)% in the weak magnetic field group, (10.72 +/- 5.67)% in the 1 h strong magnetic field group and (4.44 +/- 2.87)% in the 2 h strong magnetic field group, respectively. Johnsen's scores decreased and the testis damage increased in a dose- and time-dependent manner.</p><p><b>CONCLUSION</b>Magnetic field, either strong or weak, may damage the testis function by inducing injury to seminiferous tubules and Leydig cells, thickening of the basal membrane, derangement, exfoliation, massive apoptosis and necrosis of spermatogenic cells in the lumen, situation of the epididymis, and consequently the absence of sperm.</p>

The severity of psychic symptoms closely correlated with that of clinical ones in chronic prostatitis patients / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the correlation between the severity of psychic symptoms and that of clinical ones in CP patients.</p><p><b>METHODS</b>We investigated 300 CP patients with NIH Chronic Prostatitis Symptom Index (CPSI), Symptom Checklist 90 (SCL-90) and a self-designed questionnaire, and analyzed the correlation between the scores. Based on the scores on pain and urinary symptoms in CPSI, the patients were divided into a mild, a moderate and a severe group.</p><p><b>RESULTS</b>A total of 288 questionnaires were collected. Compared with normal males, the SCL-90 scores of the CP patients were not different in obsessive-compulsive (P > 0.05), lower in interpersonal-sensitivity (P < 0.01), higher in paranoid ideation (P < 0.05) and significantly higher in other factors and the number of positive factors (P < 0.01). There were no statistical differences among the mild, moderate and severe groups either in somatization and interpersonal-sensitivity (P > 0.05) or in phobic anxiety (P > 0.05), but there were between the mild and moderate groups in phobic anxiety (P < 0.05) and significantly among the three groups in other factors and the number of positive factors (P < 0.01 or P < 0.05). No correlation was found between CPSI and SCL-90 in the total scores.</p><p><b>CONCLUSION</b>There was a close correlation between the severity of psychic symptoms and that of clinical symptoms in CP patients. Psychotherapy, especially psychological intervention, plays an important role in the early stage of the disease.</p>
