Objective To investigate the relationship of nerve growth factor (NGF) between serum and follicular fluid in patients with polycystic ovary syndrome (PCOS), and its effect on pregnancy outcomes. Methods From December 2011 to November 2012, 65 PCOS patients suffered with in vitro fertilization-embryo transfer (IVF-ET) were included in PCOS group and 31 non-PCOS patients with IVF-ET were used as control group. The expressions of NGF in serum and follicular fluid were detected by ELISA on the injection day of chorionic gonadotropin (HCG). The expression levels of NGF in serum and follicular fluid were compared between PCOS group and control group. Results The NGF levels in serum[(14.38±0.42) ng/L] and follicular fluid[(9.61±0.49)ng/L] were significantly higher in PCOS group than those of control group[(11.39±0.38) ng/L and (7.55 ± 0.40)ng/L]. In PCOS group, NGF levels in serum [(14.22 ± 0.35)ng/L] and follicular fluid [(9.30 ± 0.31)ng/L] were significantly lower in pregnant group than those of non-pregnant group[(14.51±0.43)ng/L, (9.86±0.46)ng/L, P<0.01]. Conclusion The increased levels of NGF in serum and follicular fluid of PCOS patients contribute to the pathogenesis of PCOS. The high expression of NGF in serum and follicular fluid may be harmful to pregnancy in PCOS patients.

Osteonecrosis is the most common disorder in femoral head and scaphoid. However, avascular necrosis (AVN) in metacarpal head is a rare disease. In the present study, a 14-year-old male patient complained of right-hand pain with a limited range of motion for one month. Physical examination showed that the active flexion was 70° and the extension was limited to 30° of the metacarpophalangeal (MCP) joints. The grip strength decreased to 60% of the contralateral hand. X-rays demonstrated flattening and sclerotic changes in the long finger and ring finger of metacarpal head. CT scanning indicated cystic, osteochondral defects and sclerotic changes in metacarpal head. Imaging examination further confirmed the diagnosis of AVN in the long metacarpal finger and ring finger. After conservative treatments including splint immobilization, non-steroidal anti-inflammatory drugs (NSAIDs) and physiotherapy, the local pain symptoms of the MCP joint gradually disappeared. The range of motion of MCP joint returned to normal with the grip strength score as 105% of the contralateral hand. MRI confirmed excellent remodeling and regeneration in the metacarpal head at two years later. The clinical characteristics, diagnosis and treatments of AVN of metacarpal head were reviewed. Although radiograph examination is commonly used, early-stage osteonecrosis of the metacarpal head should be confirmed by MRI. Given the rarity of this disorder, there is no consensus on the treatments. Metacarpal necrosis is the more common disorder in adolescent patients with a history of trauma. Considering the potential of bone remodeling, juveniles with metacarpal head necrosis could recover by conservative treatments.

Objective A HPLC method was established for determination of the content of ATST in the aqueous humor of rabbits. MethodsThe mobile phase was consisting of methanol-1% triethylamine(57:43) and omeprazole (OMZ) as internal standard. The detection was carried out with an ultraviolet detector operated at 235nm. ResultsThere was linearity over the range of 2. 056~41.12 ug/ml in the humor aquosus, r=0.9997. The average recovery of ATST was 94.58 %. Intra-day and in- ter-day RSD were less than 5 % and 10 % ( n = 5), respectively. Conclusion The method is reliable. It can be used for the study on the pharmacokinetics of ATST.

Objective To assess the impact of learning curve on perioperative complications in laparoscopic radical prostatectomy (LRP) by a series of consecutive 200 cases in a single center.Methods Two hundred patients who were biopsy proved prostatic carcinoma and underwent LRP were retrospectively evaluated.All the operations were performed by professor Ma Lulin.The patients were divided into 4 groups according the time of operation.All the clinical data,including age,body mass index (BMI),preoperative PSA level,biopsy Gleason score,and clinical stage were collected.Operative parameters and peri-operative complications were evaluated,including operative time,blood loss,transfusion rate,and perioperative complications.The complications were evaluated by Clavien classification system.Results Age,BMI,PSA,prostate volume,biopsy Gleason score and clinical stage had no significant difference among the 4 groups (P > 0.05).The operative time was gradually lowered from group one to group four.Significantly less blood loss occurred after every 50 cases of LRP (P < 0.001).The complication rates were 15.5% in this series,28.0%,18.0%,12.0% and 4.0% for group one to group four respectively.The complication rate reduced as experience was gained (P =0.008).The rates of mild complications were 24.0%,14.0%,6.0% and 4.0%,and severe complication rates were 4.0%,4.0%,6.0% and 0,respectively.Conclusion With experience was gained and technique was improved,the operative time and blood loss of LRP decreased and complication rate reduced substantially.

ObjectiveTo compare the clinical characteristic and postoperative histopathological parameters in different prostate size and to assess the effect of prostate volume on histopathological outcomes in patients after laparoscopic radical prostatectomy. MethodsTwo hundred and sixteen patients from 2006 to 2011 who were proved prostatic carcinoma by biopsy and performed laparoscopic radical prostatectomy wewe retrospectively evaluated.All patients were divided into the small group ( < 30 ml,103 cases),intermediate group(30 -60 ml,71 cases) and large group ( >60 ml,42 cases) according to prostate volume.Clinical variables included age,body mass index (BMI),preoperative PSA level,prostate volume,percentage of positive needles,clinical stage,and biopsy Gleason score (GS).Histopathological parameters included pathological GS,upgrading or not compared to biopsy GS,pathological stage and surgical margins status.Preoperative clinical variables and postoperative histopatholgogical parameters were compared among the 3 prostate groups. ResultsPatients with smaller prostates had lower PSA levels than those with intermediate and larger prostates (P =0.000).They also had worse histopathological outcomes such as pathological GS ( P =0.034 ),upgrading of GS ( P =0.037 ),and pathological stage ( P =0.025 ).35.0% of patients in smaller prostate group had a positive surgical margin compare to 33.8% and 19.0% in intermediate and larger prostate groups,but there was no significant difference (P =0.152).ConclusionMen with smaller prostate may have more high-grade cancer and more advanced disease after laparoscopic radical prostatectomy.
