OBJECTIVETo evaluate the clinical effectiveness of transurethral seminal vesiculoscopy (TUSV) combined with finasteride in the treatment of recurrent hemospermia.

METHODSThis study included 32 patients with recurrent hematospermia, with the disease course of 3 months to 4 years. After administration of finasteride at 5 mg/d for 2 weeks, the patients underwent TUSV for both exploration of the causes and treatment, followed by medication with finasteride at the same dose for another 2 weeks. Postoperative follow-up was conducted for observation of the outcomes and complications.

RESULTSTUSV was successfully accomplished in all the 32 cases, which revealed 16 cases of seminal vesiculitis, 10 seminal calculi, 1 seminal vesicle cyst, 2 seminal vesicle polyps, and 3 seminal vesicle abscess. The operative time was 20 to 51 (31.0 +/- 5.2) minutes. Postoperative complications included 1 case of acute epididymitis and 3 cases of breast discomfort within the first 4 weeks. No incontinence, urethral stricture, rectal injury, retrograde ejaculation, and sexual dysfunction occurred postoperatively. All the patients but 1 were followed up for 6 months to 2 years. Twenty-nine of the cases were cured, and 2 experienced recurrence.

CONCLUSIONTransurethral seminal vesiculoscopy combined with finasteride is safe and effective for the treatment of recurrent hemospermia.

Objective To investigate the effect of curcumol on apoptosis of human gastric carcinoma cell line BGC823 and the molecular nechanisms.Methods BGC823 cells were cultured and treated with different curcumol concentration (12.5,25,50 and 100 mg/L) for 24 h and 48 h,and the growth inhibition were tested by thiazolyl blue terazolium bromide (MTF) assay.Flow cytometry (FCM) were used to measure the cell apoptosis rate and cell cycle of BGC823 cells.Caspase-3 activity was assessed by colorimetric assay.Cells treated with 100 mg/L curcunol for 48 h were collected and subjected to RTPCR and Western blot assays for the expression of Caspase-3,Bcl-2,Bax and Survivin.Results There was a time-and dose-dependent inhibition of cell proliferation of BGC823 cells by curcumol.Tbe cells in G0/G1 phase increased,and in S phase decreased on exposure to curcumol for 24 h.FCM analysis also indicated that the apoptosis rate of BGC823 cells increased in dose-dependent manner (P ＜ 0.05).Curcumol increased the activity of Caspase-3 dose-dependently (P ＜ 0.05).RT-PCR and Western blot indicated that curcumol decreased Bcl-2 and Survivin expression as well as increased Caspase-3 and Bax expression (P ＜ 0.05).Conclusions Curcumol inhibits BGC823 cell growth,arresting cells in G0/G1 phase and inducing cell apoptosis.The mechanism may be related with increasing the activity of Caspase-3,down-regulating the expression of Bcl-2 and Survivin,and up-regulating the expression of Caspase-3 and Bax.

Objective To investigate the fluctuation of the iodine deficiency disorders(IDD) through continuous monitoring on it. Methods During 2005-2008, 10 monitoring countis (city,district) of IDD were selected in Jiangxi Province. Five townships were selected in each monitoring county, one school was selected in each townships, and 40 students in 8-10 years old from each school were selected to inspect their thyroid glands and determined the idodine content of salts from their home. Among the 40 students, 20 of which were selected to determine the intelligence quotient(IQ) and 6 of which were selected to determine urine iodine. Thirty pregnant women were also selected to determine the urine iodine in each monitoring county. Twenty students of 5th grade in each school and 5 housewives living nearby the school were selected to carry out the questionnaire survey of health education about IDD. Results Monitoring results showed the average goiter rote of 8-10 years old students was between 2.00% and 4.60% during 2005-2008. The rate of IQ of the students higher than 90 was all above 76% each year. The median of urine iodine of students and pregnant women was higher than 100 μg/L, and the proportion of people whose urine iodine content was lower than 50 μg/L was below 4% each year. The rate of inhabitant taking qualified idodine salt wasn't lower than 95%. The pass rate of the questionnaire survey of health education about IDD was between 11.67% and 43.50% in students and 92.50%-99.60% in housewives. Conclusions The situation of iodine deficiency in Jiangxi Province has been greatly improved, reaching the standard of eliminating IDD.
