BACKGROUND: Removal of immunosuppressants in patients with recurrent tumor in long-term following organ transplantation is always a hot controversial point in academic circles. To further elevate clinical efficiency, people began to invent new immunosuppressant and studied immune efficiency of various immunosuppressant component. They tried to reduce the application of cyclosporin A (CsA).OBJECTIVE: To analyze the CsA safe withdrawal of a case of kidney recipients, at 18 years after renal transplantation, who developed bladder carcinoma and renal pelvic carcinoma at 11 years and 18 years after transplantation, respectively. METHODS: After identified diagnosis, we performed transurethral resection of bladder tumor (TURBt) and total nephroureterectomy merobladder excision. Pathologic examination revealed grade Ⅰ-Ⅱ of bladder and renal pelvic transitional cell carcinoma. After the operation, patient was treated with immune suppression program of CsA withdrawal gradually in 12 days.Within 12 days, 5 mg CsA was decreased every 3 days, and complete withdrawal was done at 12 days. The dosage of azathioprine tablets and prednisone acetate tablets was not changed. Serum creatinine levels were rechecked every 3 days during drug withdrawal, and blood pressure, urine volume, physical symptom of patients and ultrasound of transplanted kidney were observed.RESULTS AND CONCLUSION: During the three months of CsA withdrawal, the blood creatinine levels were from 65 to indicated that the CsA gradually withdrawal of a case of kidney recipients after renal transplantation, who developed transitional cell carcinoma and was performed transurethral resection of bladder tumor (TURBt) and total nephro- ureterectomy merobladder excision, was safe. No tumor relapse or diversion was found.

Rhynchosia volubilis Lour has been a major drug in a folk prescription for contraception in China, whereas its mechanism remains unknown. Its antifertility effects on male mice and antimicrobial activities on sexually transmitted infection (STI) pathogens were previously reported. This study was undertaken to develop the n-Butanol extract of Rhynchosia volubilis Lour (BERVL) as a spermicidal agent with STI prevention. The spermicidal activities of BERVL with different doses were assessed using selected high-motile sperms of normal human semen samples, and their inhibitory effects on Lactobacillus acidophilus were determined. The mechanism of the spermicidal activity was explored by aqueous Eosin Y and Hoechst 33342/PI staining. The results showed spermicidal activities and inhibitory effects of BERVL on Lactobacillus acidophilus were dose-dependent. Dose of 90 mg/mL BERVL terminated all progressive sperm motility within 2 min, and had slight inhibitory effect on Lactobacillus acidophilus, suggesting it was an effective and safe dose for contraception use. About 80% sperms exposed to BERVL displayed changes consistent with high permeability of head membrane. It is concluded that BERVL as spermicide has advantages over N-9 with strong ability to instantaneously kill human sperm and possesses light inhibitory effect on Lactobacillus acidophilus.

Cancer, an abnormal cell proliferation resulted from multi-factors,has the highest morbidity and mortality among all the serious diseases. Considerable progress has been made in cancer biology in recent years. Tumor immunology, cancer stem cells (CSCs), autophagy, and epithelial-mesenchymal transition (EMT) have become hot topics of interests in this area. Detailed dissection of these biological processes will provide novel directions, targets, and strategies for the pharmacological evaluation, mechanism elucidation, and new drug development of traditional Chinese medicine.

OBJECTIVETo investigate the value of detection of AMACR (P504S), P63 and 34betaE12 cocktail in the early diagnosis of prostate cancer (PCa).

METHODSThe expressions of AMACR, P63 and 34betaE12 were examined in the biopsy specimens of 42 cases of prostate cancer, 12 cases of high-grade prostatic intraepithelial neoplasia (HGPIN) and 30 cases of benign prostatic hyperplasia (BPH) using the Maxvision single-step immunohistochemical method with triple-antibody cocktail (AMACR/P63/34betaE12) staining and double-color chromogens in single paraffin sections .

RESULTSThe expressions of AMACR, P63 and 34betaE12 were significantly different between PCa and BPH (P < 0.01). The staining of PCa was positive for AMACR and negative for P63 and 34betaE12, and the positivity rate of AMACR was 100%. BPH was strongly expressed for P63 and 34betaE12, but negatively for AMACR. The expression of AMACR was significantly different between HGPIN and BPH (P < 0.01), but not between HGPIN and PCa (P > 0.05), and the positivity rate of AMACR in HGPIN was 91.67%. However, the expressions of P63 and 34betaE12 were significantly different between HGPIN and PCa (P < 0.01), but not between HGPIN and BPH (P > 0.05), and the positivity rate of AMACR in HGPIN was 100%. The level of AMACR expression was not correlated with PCa Gleason score (P > 0.05).

CONCLUSIONAMACR is a sensitive and specific marker for PCa. P63 and 34betaE12 cocktail staining can increase the sensitivity and specificity of the basal cell detection. The immunohistochemical analysis with triple-antibody cocktail (AMACR/P63/34betaE12) staining and double-color chromogens can improve diagnostic accuracy and has an important applied value for the early diagnosis of prostate cancer.
