Cryptorchid testicular torsion in children: characteristics and treatment outcomes / 亚洲男科学杂志(英文版)

This study aimed to review and compare the characteristics and treatment outcomes of cryptorchid testicular torsion in pre- and postpubertal children. We reviewed the clinical data of 22 patients with testicular torsion complicated by cryptorchidism who were treated between January 2010 and December 2019. Patients were categorized into prepubertal (1 month to 9 years; n = 12) and postpubertal groups (10-16 years; n = 10). The age at presentation, clinical presentations, physical examination, and operation outcomes were assessed. The common clinical presentations in both groups were inguinal pain and a tender inguinal mass. Patients in the prepubertal group were significantly more likely to present with restlessness (33.3%) than those in the postpubertal group (0%; P = 0.044). After detorsion, testicular blood flow recovered during surgery in 25.0% of the prepubertal and 80.0% of the postpubertal patients (P = 0.010). Orchiectomy was required in 50.0% of the prepubertal and 20.0% of the postpubertal patients (P = 0.145). Of the 22 patients with follow-up data, the rates of testicular salvage were significantly different, at 16.7% in the prepubertal patients and 60.0% in the postpubertal patients (P = 0.035). Cryptorchid testicular torsion has various manifestations. Although an empty hemiscrotum and a painful groin mass were common in both groups, restlessness was more prevalent in the prepubertal patients during early testicular torsion onset than that in the postpubertal patients. Notably, the testicular salvage rate was significantly lower in the prepubertal patients than that in the postpubertal patients.

Estimation of effects of liuwei Dihuang Wan on anti-inflammation in rat by HPLC-UV based metabonomic method / 中国中药杂志

<p><b>OBJECTIVE</b>To understand the possibility of estimating the anti-inflammation effect of Liuwei Dihuang Wan (LWW) in rat by having developed HPLC-UV metabonomic technology.</p><p><b>METHOD</b>The hydrophilic or lipophilic constituent group of LWW was extracted by distilled water or acetic ether respectively. The anti-inflammation effects of different LWW dosages and extractions were measured by traditional method respectively. Then, metabonomic analysis was performed.</p><p><b>RESULT</b>The high dosage of LWW extraction (16.5 g x kg(-1))could inhibit the swell of rat palm significantly, but there are not statistically significant effect of low dosage group. Nevertheless, the metabonomic study showed that LWW extraction could restore obviously the rat HPLC-UV urinary profiling disturbed by inflammation in low dosage, especially the hydrophilic constituent group.</p><p><b>CONCLUSION</b>Our study indicated that the developed metabonomic technology based on HPLC-UV might be used as a potentially powerful tool for estimating the anti-inflammation effect of LWW with sensitivity and integrity.</p>

Effect of Supportan on nutritional status and immune function of late-staged gastric cancer patients undergoing chemotherapy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate the effect of Supportan, an enteral nutrition (EN) specific for tumor patients, on the nutritional status and immune function of late-staged gastric cancer patients undergoing chemotherapy.</p><p><b>METHODS</b>Sixty-six late-staged gastric cancer patients undergoing chemotherapy were randomly divided into EN group (n=33) and control group (n=33). During chemotherapy, the patients in EN group received Supportan and the patients in the control group received basic diet. On the 14th day before chemotherapy and after chemotherapy, nutritional status and cell immune indicators were evaluated.</p><p><b>RESULTS</b>As for nutrition indicators, there were no significant differences in EN group before and after chemotherapy (P > 0.05). Total protein, hemoglobin, prealbumin and transferrin significantly decreased after chemotherapy compared with those before chemotherapy in the control group (P< 0.01). The levels of CD4(+), CD8(+) T cells and CD4/CD8 were significantly increased, and NK cells, serum levels of IL-1, IL-6 were significantly decreased after chemotherapy in EN group (P< 0.01). The levels of IL-6 and TNF-alpha were significantly higher after chemotherapy than those before chemotherapy in the control group(P< 0.01). Curative effects of immune nutrition in EN group were superior to that in the control group, however, the differences were not statistically significant. The incidences of nausea, vomiting and marrow inhibition in Supportan group was lower compared with those in the control group, but with no significant difference.</p><p><b>CONCLUSION</b>Supportan can prevent malnutrition of the late-staged gastric cancer patients undergoing chemotherapy, and improve immune function and alleviate adverse effects of chemotherapy.</p>
