OBJECTIVETo evaluate the functional outcomes of modified limited "L" incision beside the Achilles tendon with distraction bone block arthrodesis in treatment of subtalar osteoarthritis.

METHODSFrom March 2009 to September 2012, a total of 22 cases of old calcaneus fractures with subtalar osteoarthritis were treated with modified limited "L" incision and distraction bone block arthrodesis including 13 males and 9 females with a mean age of 35.3 years old (ranged 22 to 49). The mean time from calcaneal fracture was 21 months (ranged 11 to 32). According to the Stephens-Sanders classification, 16 cases were type II and 6 were type III. The modified-AOFAS ankle-hindfoot score was used for functional outcomes evaluation.

RESULTSThere was one incision necrosis and no infection, implant failure, bone-graft absorbed or talus necrosis was note at the follow-up time. A total of 21 cases were followed up for a mean time of 29 months (ranged from 18 to 46 months). All of the cases reached a bony union within 4 months postoperation. The mean modified-AOFAS ankle-hindfoot score was 82.6 points (ranged from 66 to 92 points),reached a significantly improvement in comparing with the mean preoperative score (50.8 points,ranged from 32 to 65 points, P < 0.01).

CONCLUSIONThe modified limited"L" incision beside the Achilles tendon with distraction bone block arthrodesis is an acceptable and alternative treatment method for subtalar osteoarthritis. This method is easy to use and with less complication. It can correct the main pathological changes and reach good functional outcomes.

Objective　To investigate the feasibility of applying transvescal approach laparoendoscopic single-site radical prostatectomy (TVSSLRP) and assess the oncological and functional outcomes.Methods　Eight patients with clinically localized prostate cancer (PCa) of low risk underwent TVSSLRP.Demographic data were accrued including patient age,body mass index (BMI),preoperative PSA level,the International Index of Erectile Function 5,biopsy Gleason score,clinical TNM stage and D'Amico risk classification.One surgeon performed all TVSSLRP procedures.A homemade triple-port was introduced percutaneouly into the bladder to establish pneumovesicum through a 4 cm incision.The major steps of the surgery were described as follows:initial incision was made along posterior margin of the bladder neck to expose bilateral vas deference and spermatic vesicle.After opening Denonvilliers' fascia and extending the space to lateral prostatic pedicles,an intra-fascial nerve sparing procedure was performed.The puboprastatic ligaments were then separated close to the prostate surface and the dorsal vein complex was cautiously swept off.Subsequently,careful apical dissection and urethral transection was sequentially conducted. To reduce the tension of vesico-urethral anastomosis,3 additional incisions parallel to vesio-urethral margin were created and a novel tension - reduced V-LocTM barbed polydioxanone sutures was used.　Results　All the operations were successfully performed and there was no conversion to standard laparoscopic approach or open surgery.The total operative time range was 75 - 180 min with mean time of 125 min.The blood loss was 85 -450 ml with mean 140 ml and no blood transfusion was required.The catheter was removed after a mean (range) of 14 (9 -16) days.No intra-operative complications occurred. No patient had positive surgical margins.The mean (range) hospital stay was 17 (13 -25) days after surgery. All the cases were continent after removal of the catheter.No cases demonstrated vesico-urethral stricture and biochemical recurrence on 12 - 18 months follow up postoperatively.　Conclusions　TVSSLRP is technically feasible for cases with organ-confined prostate cancer with good oncological and functional results.

Objective To explore the potential mechanism of adrenal androgen excess in patients with polycystic ovary syndrome (PCOS), ACTH stimulation test was conducted and the polymorphisms in the promoter region of CYP21 A2 gene were screened to verify the variations related to the responsiveness to ACTH stimulation. Methods 30 healthy women and 101 PCOS patients, matched for age, were recruited from Ruijin hospital. Blood biochemical examinations were taken and sex hormone profiles obtained at baseline. 17 hydroxyprogesterone( 17OHP)was measured at 0 and 60 min in an ACTH stimulation test. The -710 bp -1 bp of the promoter region of CYP21A2 was sequenced in 87 PCOS patients and 30 control subjects. Results According to the post-stimulation 17 OHP levels obtained from 30 healthy women,PCOS patients were allocated into one group with high responsiveness to ACTH ( HR-PCOS, n = 21) and the other with normal responsiveness to ACTH ( NR-PCOS, n = 80). Compared with NR-PCOS subjects, HR-PCOS patients had higher testosterone( P<0.05), basal and post-stimulation 17OHP (both P<0.01)and dehydroepiandrosterone sulfate levels (P<0.05 or P<0.01) .whereas serum cortisol and androstenedione levels were not significantly different before and after ACTH stimulation test. The genotypes of locus -535 were well correlated with post-stimulation 17OHP levels (r = 0. 20,P = 0. 03) in PCOS patients and the control subjects. The genotype T/T or allele T was significantly more frequent in subjects with a higher fertile of post-stimulation 17OHP (P<0.05 or P<0. 01). The odds ratio(OR)for higher responsiveness to ACTH in women with allele T at -535 was 3. 69 (95% CI 1. 69-8. 06,P = 0. 000 7). Conclusions The PCOS patients with higher responsiveness to ACTH are characterized by severe hyperandrogenemia and adrenal androgenexcess,suggesting that adrenal androgen excess in some PCOS patients may be due to higher responsiveness to ACTH. The polymorphism of -535C>T in the promoter region of CYP21 A2 may play a role in regulating 21 hydroxylase gene expression and further influencing 17OHP responsiveness to ACTH.
