OBJECTIVEOvarian fibrosis is characterized by excessive proliferation of ovarian fibroblasts and deposition of extracellular matrix (ECM) and it is one of the principal reasons for ovarian dysfunction. This review aimed to investigate the pathogenetic mechanism of ovarian fibrosis and to clarify the relationship between ovarian diseases and fibrosis.

DATA SOURCESWe searched PubMed for English language articles published up to November 2016. The search terms included ovarian fibrosis OR fibrosis, ovarian chocolate cyst OR ovarian endometrioma, polycystic ovarian syndrome (PCOS), premature ovarian failure, ECM, matrix metalloproteinases (MMPs), tissue inhibitors of matrix metalloproteinases (TIMPs), transforming growth factor-beta 1 (TGF-β1), connective tissue growth factor (CTGF), peroxisome proliferator-activated receptor gamma (PPAR-γ), vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), and combinations of these terms.

STUDY SELECTIONArticles were obtained and reviewed to analyze the pathogenic mechanism of ovarian fibrosis and related ovarian diseases.

RESULTSMany cytokines, such as MMPs, TIMPs, TGF-β1, CTGF, PPAR-γ, VEGF, and ET-1, are involved in ovarian fibrogenesis. Ovarian fibrogenesis is associated with various ovarian diseases, including ovarian chocolate cyst, PCOS, and premature ovarian failure. One finding of particular interest is that fibrogenesis in peripheral tissues around an ovarian chocolate cyst commonly causes ovarian function diminution, and therefore, this medical problem should arouse widespread concern in clinicians worldwide.

CONCLUSIONSPatients with ovarian fibrosis are susceptible to infertility and tend to have decreased responses to assisted fertility treatment. Thus, protection of ovarian function should be a priority for women who wish to reproduce when making therapeutic decisions about ovarian fibrosis-related diseases.

Nine morphologic traits, plant height, ground diameter, leaf length, leaf width, leaf area of plant, leaf fresh weight, blades, length/width ratio, plant fresh weight of Anoectochilus roxburghii from 13 different areas were determined for correlation analysis, path analysis and principal components analysis. Different source of morphological trait variation coefficient of A. roxburghii was 2.96% -12.59%, plant fresh weight was significant positively correlated with ground diameter, plant height and leaf number, and positively correlated with leaf fresh weight. Path analysis showed that plant height had the largest positive direct effect on plant fresh weight, the leaf fresh weight and blades number had indirect effects on the plant fresh weight. Through principal component analysis, morphological traits of A. roxburghii can be divided into "Determinants of high-yielding morphology" and "Determinants of leaf production". In the actual process of production and breeding of A. roxburghii, we should pay attention to plant height, leaf fresh weight, blades numbers and other traits.

OBJECTIVETo evaluate the feasibility and short-term clinical effect of transperitoneal laparoscopic modified retroperitoneal lymph node dissection (LmRPLND) in the management of clinical Stage I nonseminomatous germ cell testicular tumors.

METHODSFrom October 2004 to July 2006, 7 patients aged 26-36 (mean 30) years underwent LmRPLND with modified unilateral template dissection for clinical Stage I nonseminomatous germ cell testicular tumors, which were 3.0 cm x 2.5 cm x 2.0 cm to 6.5 cm x 4.5 cm x 3.0 cm in size, 3 cases on the left and 4 on the right, all diagnosed by ultrasound, computerized tomography (CT) and chest X-ray and confirmed by biopsy following radical orchiectomy. Those with positive lymph nodes received 3 courses of chemotherapy.

RESULTSSuccess was achieved in all the 7 cases, the operative time ranging from 120 to 210 min (mean 160 min), blood loss from 50 to 200 ml (mean 150 ml), and with no blood transfusion. The drainage tubes were removed 1-2 days after surgery. The mean postoperative hospital stay was 5.5 days. The follow-up lasted 6-32 (mean 14) months, which revealed normal erection and ejaculation in all the patients, but no major postoperative complications. Pathologically, lymph nodes were negative in 6 cases and positive (1/18) in 1. Normal results were obtained in HCG and AFP tests as well as in retroperitoneal ultrasound and chest X-ray examinations. The patient with positive lymph nodes was treated by adjuvant chemotherapy for 3 courses and found free of malignancy during a 6-month follow-up.

CONCLUSIONLmRPLND is a safe and minimally invasive treatment option for patients with clinical Stage I nonseminomatous germ cell testicular carcinoma. With fewer complications and faster recovery, it appears to be a desirable substitute for the open procedure.

By using rice SSRP, RAPD and AFLP molecular markers, the genome of rice transgenic line "Minghui 63-Xa21" was analyzed. 32 SSRP primers, 42 RAPD primers and 8 AFLP primers could produce obvious PCR bands in the analysis of at least 12 individual plants selected randomly from "Minghui 63-Xa21" T3 generation. Totally 550 PCR bands, equivalent to 550 genomic sites, were detected. Different individual plants of the transgenic homozygous line displayed almost the same PCR pattern. Compared with the control "Minghui 63", no difference was found in their PCR patterns. This indicated that the introduction of Xa21 into the genome of "Minghui 63" did not change these 550 genome sites and their heredity. Very few variant PCR bands were observed in some individual plants from both "Minghui 63-Xa21" and "Minghui 63". However, the variant percentage was equivalent between the transgenic line and the non-transgenic control line.
