<p><b>OBJECTIVE</b>To explore the diagnostic values of interleukin-12 (IL-12) and interferon-γ (IFN-γ) for the patients with acute leukemia (AL).</p><p><b>METHODS</b>A total of 76 cases of AL were enrolled in this study, and the 40 healthy persons were used as control group. The levels of IL-12 and IFN-γ were determined by enzyme linked immunosorbent assay (ELISA). The results were analyzed.</p><p><b>RESULTS</b>The levels of IL-12 and IFN-γ in the untreated AL group, ALL and ANLL groups were lower significantly than those in the control group (P<0.05), there was no significant difference between untreated AL and ANLL groups (P>0.05). The levels of IL-12 and IFN-γ in CR patients of AL group after treatment obviously higher than that of patients before treatment (P<0.05), but there was no significant difference as campared with that in control. The levels of IL-12 and IFN-γ in NR patients of AL group after treatment were obviously lower than that in control group (P<0.05), but there was no significant difference in comparision with patients before treatment (P>0.05). The levels of IL-12 and IFN-γ of AL-CR and AL-NR patients before treatment were not significant difference before treatment (P>0.05). The levels of IL-12 and IFN-γ of AL-CR patients obviously higher than that in AL-NR patients (P<0.05). According to immure classification, the levels of IL-12 and IFN-γ of patients in untreated group were not significant difference. In regard to the clinical risk degree, the level of IL-12 of patients in untreated group was not obvious difference (P>0.05), but the level of IFN-γ of patients in untreated group was obvious different (P<0.05). The level of IL-12 of patients in untreated group positively correlated with level of IFN-γ (r=0.735, P<0.05), but the level of IL-12 did not significantly correlated with the level of IFN-γ (r=0.292, P>0.05).</p><p><b>CONCLUSION</b>The serum levels of both IL-12 and IFN-γ are lower, but the changes of both serum levels may be helpful to diagnose and treatment of AL patients.</p>

Gene therapy study on bladder cancer with recombinant adenoviral vector carrying LRIG1 gene driven by Survivin promoter / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the treatment efficiency and mechanism of recombinant adenoviral vector carrying LRIG1 gene driven by Survivin promoter for bladder cancer.</p><p><b>METHODS</b>Human bladder cancer cell line BIU87 and immortalized human bladder epithelial cells SV-HUC-1 were infected with Ad-Surp-LRIG1 and Ad-LRIG, respectively. The selective infection efficiency of Ad-Surp-LRIG1 and Ad-LRIG were evaluated by checking the expression of epidermal growth factor receptor (EGFR). The MTT method was used to test cell growth inhibition ratio of Ad-Surp-LRIG1 and Ad-LRIG. Heterotransplanted models of human bladder cancer cell line BIU87 cells in nude mice were established. The mice were randomly divided into 3 groups during the experiment: Ad-Surp-LRIG1 group received viral supernatant solution of Ad-Surp-LRIG1 by tail vein injection; Ad-LRIG group received viral supernatant solution of Ad-LRIG by tail vein injection; and PBS group received phosphate buffer solution (PBS). The growth of tumors were observed and the growth curve was mapped. The expression of LRIG1 and EGFR were examined by reverse transcription PCR (RT-PCR).</p><p><b>RESULTS</b>When Multiplicity of infection was 25, the transfection efficiency of Ad-Surp-LRIG1 was 74.56% in BIU87 cells and 0 in SV-HUC-1 cells (χ² = 58.640, P = 0.000), while the transfection efficiency of Ad-LRIG was 68.27% in BIU87 cells and 72.52% in SV-HUC-1 cells (χ² = 0.075, P = 0.784). The transfection efficiency difference of Ad-Surp-LRIG1 and Ad-LRIG in BIU87 cells was not statistically significant (χ² = 0.016, P = 0.898). Compared with PBS, Ad-Surp-LRIG1 and Ad-LRIG1 could inhibit BIU87 cell growth, the difference was significant in 4 days after transfection (F = 15.960, P = 0.000). There was not significant difference in cell growth rate of Ad-Surp-LRIG1 group and Ad-LRIG1 group. The tumor growth rate in Ad-Surp-LRIG1 group was slower than that in the other 2 groups. The tumor quality in Ad-Surp-LRIG1 was lighter than that in the other two groups, the differences were statistically significant (F = 97.860, P = 0.000), the quality difference in Ad-LRIG1 group and PBS group was not statistically significant difference (t = 1.73, P = 0.06). Compared with Ad-LRIG1 group and PBS group, the mRNA expression of LRIG1 was obviously up-regulated and that of EGFR was down-regulated in Ad-Surp-LRIG1 group (P < 0.01).</p><p><b>CONCLUSIONS</b>The recombinant adenoviral vector of Ad-Surp-LRIG1 could selectively transfected BIU87 cells, which could inhibit significantly the growth of bladder cancer in vivo and in vitro, the mechanism may be partly LRIG1 can downgrade the expression of EGFR.</p>

Sexual function and mental state in patients with redundant prepuce or phimosis / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the correlation of sexual dysfunction with psychological abnormalities by analyzing the sexual function and mental state of the patients with redundant prepuce or phimosis.</p><p><b>METHODS</b>This study included 216 randomly selected patients with redundant prepuce or phimosis and 85 normal male controls. We conducted investigations among the subjects using a questionnaire on the general data of the patients, Chinese Index of Sexual Function for Premature Ejaculation (CIPE), International Index of Erectile Function (IIEF), and Symptom Checklist 90 (SCL-90). Then we assessed the status of premature ejaculation (PE) and erectile dysfunction (ED), calculated the incidence of psychological abnormalities, such as depression and anxiety, and analyzed the correlation of PE and ED with the mental state of the patients.</p><p><b>RESULTS</b>The PE and ED patients scored significantly higher than normal controls on SCL-90, somatization, compulsion, depression, anxiety and other factors (P < 0.05). CIPE scores were correlated with the scores on SCL-90, somatization, compulsion, interpersonal sensitivity, depression, anxiety and other factors, while ED-related scores showed no correlation with the scores on SCL-90 and other factors.</p><p><b>CONCLUSION</b>Patients with redundant prepuce or phimosis have poor mental health, and there is an interaction between PE and the mental state of the patient.</p>

A recommendable standard protocol of adult male circumcision with the Chinese Shang Ring: outcomes of 328 cases in China / 中华男科学杂志

<p><b>OBJECTIVE</b>Standardization of and training in adult male circumcision can significantly reduce its complication rate. Currently no such program exists for its standardization and training, making it difficult to guarantee the quality of male circumcision services. We therefore established a standardized surgical protocol for adult male circumcision in China using the Shang Ring, and applied it to a clinical study examining the performance of the Shang Ring in adult male circumcision.</p><p><b>METHODS</b>A total of 328 adult men aged 18-58 (mean 27.8) years, 25 with phimosis and 303 with redundant prepuce, underwent circumcision with the Shang Ring, and evaluation of the operation time, pain scores (using the visual analog scale), postoperative complications, time for wound healing, and their satisfaction with the postoperative appearance.</p><p><b>RESULTS</b>The operation time was 4.7 +/- 1.3 minutes. The pain scores were 0. 2 +/- 0.6 during the surgery, 1.6 +/- 1.0 twenty hours postoperatively, 1.7 +/- 1.1 twenty hours prior to the ring removal, and 2.7 +/- 1.4 during the ring removal. Complications included infection in 2 (0.6%), bleeding in 2 (0.6%), and wound dehiscence in 2 (0.6%) of the patients. None of the patients with wound dehiscence required postoperative suturing and all were managed conservatively instead. Sixteen of the patients (4.9%) experienced penile edema. The time for complete wound healing after circumcision was 20.3 +/- 6.7 days. The rate of the patients'satisfaction was 99.7% (327/328).</p><p><b>CONCLUSION</b>The standard protocol of adult male circumcision with the Shang Ring has the advantages of short operation time, slight pain, low rate of complications, and high satisfaction and acceptance of the patients. Strict standardization of the surgical protocol can maximize its clinical advantages for adult male circumcision.</p>
