Clinical research on auricular point therapy for 1477 cases of biased constitution / 中国针灸

<p><b>OBJECTIVE</b>To observe the efficacy of biased constitution patients treated by auricular point therapy on the basis of "preventive treatment" theory.</p><p><b>METHODS</b>By means of self-control, 1477 cases of biased constitution were regulated by auricular point sticking therapy or acupuncture, and follow-up and statistical analysis were conducted to observe the efficacy.</p><p><b>RESULTS</b>There were 322 markedly effective patients, 914 effective patients, 241 failed patients and the total effective rate was 83.7% (1236/1477).</p><p><b>CONCLUSION</b>The comprehensive auricular treatment which is easy to operate and acceptable for patients has obvious effect in biased constitution patients. As a new direction of the "preventive treatment" theory, it can be promoted to be a new intervention way of health care.</p>

Sonographic features and clinical significance of transrectal ultrasonography in obstructive azoospermia / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the ultrasonographic features of obstructive azoospermia and to evaluate transrectal ultrasonography in the diagnosis of the disease.</p><p><b>METHODS</b>We performed transrectal ultrasonography for 248 patients with obstructive azoospermia, observed the sonographic features of the prostate gland, seminal vesicle and ejaculatory duct.</p><p><b>RESULTS</b>The average volume of the prostate gland of the studied group was 13.2 ml. A total of 111 cases showed normal sonographic features, 39 cases bilateral seminal vesicle defect, 33 cases bilateral seminal vesicle aplasia, 23 cases unilateral seminal vesicle defect and contralateral seminal vesicle aplasia, 28 cases bilateral and 14 cases unilateral seminal vesicle dilatation. Of the 42 cases of seminal vesicle dilatation, 18 had ejaculatory duct dilatation and 17 had cysts in the midline of the prostate.</p><p><b>CONCLUSION</b>Obstructive azoospermia varies in kind. Transrectal ultrasonography can reveal the details of the prostate, seminal vesicle and ejaculatory duct and help to classify obstructive azoospermia and determine the location of the lesion.</p>

Diagnostic value of urodynamic parameters multianalysis in the evaluation of bladder outlet obstruction resulting from benign prostatic hyperplasia / 中华男科学杂志

<p><b>OBJECTIVE</b>To construct a function model that can be used in the diagnosis bladder outlet obstruction (BOO) resulting from benign prostatic hyperplasia, and to develop a diagram allowing the judgement of bladder outlet for patients with different detrusor contractility, especially with impaired one.</p><p><b>METHODS</b>Urodynamic and clinical data of 131 men were analyzed retrospectively. By Logistic analysis, a function model was constructed. Based on the model, a diagram allowing the evaluation of bladder outlet was drawn. The cutoff point for diagnosing BOO with the function model and the curve was confirmed by ROC curve analysis.</p><p><b>RESULTS</b>The function model (BOOI) was obtained by the formula 5.03 x residual fraction + 0.04 x PdetatQmax - 0.20 x Qmax - 0.91 + alpha (alpha = 0 for those with low pressure-low flow on P-FS, alpha = 1.42 for high pressure-low flow, alpha = -7.30 for high pressure-high flow). The cutoff point for BOOI diagnosing BOO was 0.36. When validated, the sensitivity, specificity, positive predictive value, and negative predictive value were 85.7%, 91.7%, 96.0% and 73.3% respectively.</p><p><b>CONCLUSION</b>The BOOI, with an easy calculation mode, could predict the probability of BOO. The sensitivity and specificity of the criterion for the diagnosis of BOO were satisfactory. The curve we drew could help to differentiate the obstructed men with low pressure-low flow and thus benefit them by surgical relief of their obstruction.</p>
