The clinical predictive factors for malignant testicular histology remain unclear because of the low prevalence. Therefore, the aim of this study was to investigate predictors of malignant histology for testicular masses and decide more testis-sparing surgeries before surgery. This retrospective study enrolled 325 consecutive testicular mass patients who underwent radical orchiectomy (310/325) or testicular preserving surgery (15/325) from January 2001 to June 2016. The clinicopathological factors, including tumor diameter, cryptorchidism history, ultrasound findings, serum alpha-fetoprotein, and human chorionic gonadotropin (HCG) levels, were collected retrospectively for statistical analysis. A predictive nomogram was also generated to evaluate the quantitative probability. Among all patients, 247 (76.0%) were diagnosed with a malignant testicular tumor and 78 (24.0%) with benign histology. Larger tumor diameter (per cm increased, hazard ratio [HR] = 1.284, P = 0.036), lower ultrasound echo (HR = 3.191, P = 0.001), higher ultrasound blood flow (HR = 3.320, P < 0.001), and abnormal blood HCG (HR = 10.550, P < 0.001) were significant predictive factors for malignant disease in all testicular mass patients. The nomogram generated was well calibrated for all predictions of malignant probability, and the accuracy of the model nomogram measured by Harrell's C statistic (C-index) was 0.92. According to our data, the proportion of patients who underwent radical orchiectomy for benign tumors (24.0%) was much larger than generally believed (10.0%). Our results indicated that the diameter, ultrasonic echo, ultrasonic blood flow, and serum HCG levels could predict the malignancy in testicular mass patients.

OBJECTIVETo explore the protective effect of electroacupuncture (EA) pretreatment on ovarian function in rats with ovulation induction.

METHODSThirty SD female rats were numbered according to random number table. According to vaginal smear method, rats of estrus were divided into a normal group (10 rats) and cohabitated with male SD rats with the proportion of 1:1. With computer-generated random number, the remaining rats were divided into a model group and an EA group, 10 rats in each one. The model of superovulation was established with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (HCG) in the model group and EA group. Before model establishment and cohabitation, rats in the EA group were treated with EA at "Guanyuan (CV 4)" and "Sanyinjiao (SP 6)", once for 15 min, for consecutive 7 days. Rats in the normal group and model group received no further treatment. The third day 23:00 pm after cohabitation, blood samples in three groups were collected to test the level of estradiol (E₂) and progesterone (P). After the rats were sacrificed, the HE staining method was applied to observe the morphological changes of ovarian tissue; the immunohistochemical method was applied to measure the expression of vascular endothelial growth factor (VEGF) and its receptor VEGFR-2; the real-time quantitative PCR technique was applied to measure the gene expression of VEGF and VEGFR-2.

RESULTSThe number of ovarian follicle in the EA group was higher than that in the model group and normal group (all P < 0.05); the ratio of corpus luteum size to ovarian size in the EA group was lower than that in the model group (P < 0.01). The ratio of plasma estradiol to progesterone in the EA group tended to be normal group (P < 0.05) and lower than that in the model group (P < 0.01). The protein expression of VEGF and VEGFR-2 in lutein granulosa cell and follicular fluid in the EA group was lower than that in the model group (P < 0.05); gene level of VEGF and VEGFR-2 in ovarian tissue in the EA group was lower than that in the model group (P < 0.05, P < 0.01).

CONCLUSIONEA pretreatment has certain protective effect on ovarian function in rats with ovulation induction, which is likely to be related to regulation of VEGF and its receptor.

OBJECTIVETo explore the best therapy for infertility caused by polycystic ovary syndrome (PCOS).

METHODSOne hundred and twenty patients were randomized into three groups, a clomi-phene group (group A), an acupuncture-moxibustion + Chinese medicine group (group B) and a clomiphene + acupuncture-moxibustion+ Chinese medicine group (group C), 40 cases in each one. In the group A, since the 5th day of menstruation, clomiphene was prescribed for oral administration. In the group B, on the 5th day of menstruation, warm needling therapy was applied at Zhongji (CV 3), Guanyuan (CV 4), Guilai (ST 29), etc. Additionally, the Chinese herbal medication for tonifying the kidney and activating blood circulation was provided. In the group C, the therapy as the group B was combined on the basis of the treatment as the group A. The treatment lasted continuously for 3 menstrual cycles. The endometrial thickness, endometrial type and cervical mucus score on human chorionic gon adotropin (HCG) day, and ovulatory cycle rate, clinical pregnancy rate and abortion rate after treatment were observed in the patients of the three groups.

RESULTS1) HCG day cervical mucus score, endometrial thickness and endometrial morphology (A type rate): the results in the group C were better than those in the group A (all P<0.01); the results in the group B were better than those in the group A (all P<0.05). The difference in the endometrial thickness was not significant in comparison between the group C and the group B (P>0.05). The cervical mucus score and endometrial morphology (A type rate) in the group C were better than those in the group B (both P<0.05). 2) The ovulatory cycle rates in the group A and group (C were higher than that in the group B (both P<0.05), the pregnancy rate in the group C was higher than that in the other groups (both P<0.05), and the early abortion rate in the group C was lower than that in the group A and group B (both P<0.01). 3) Follicle diameter from 18 mm to 20 mm and endometrial thickness: the differences were not significant between the normal pregnancy patients and the early abortion patients (both P>0.05). The endometrial morphology A type rate in the normal pregnancy patients was higher than that in the early abortion patients (P<0.05).

CONCLUSIONThe combined therapy of acupuncture, herbal medicine and clomiphene improves the pregnancy rate and reduces early abortion rate by effectively improving HCG day cervical mucus, endometrial thickness and morphology. The efficacy is apparently superior to the simple medication with clomiphene and the combined application of acupuncture and herbal medicine.

OBJECTIVETo explore the role of the basic fibroblast growth factor (bFGF) in the directional differentiation of bone marrow mesenchymal stem cells (BMSCs) into Leydig cells.

METHODSAfter purification and identification, we inoculated the third-generation BMSCs of SD rats onto a six-orifice board and then randomly divided them into groups A (normal saline control), B (human chorionic gonadotropin [hCG] + platelet-derived growth factor [PDGF] induction), C (hCG + PDGF + 5.0 ng/ml bFGF induction), D (hCG + PDGF + 10.0 ng/ml bFGF induction), and E (hCG + PDGF + 20.0 ng/ml bFGF induction). On the 7th, 14th and 21st day of induction, we observed the morphological changes of the cells and measured the level of testosterone (T) and expression of 3 beta hydroxy steroid dehydrogenase (3β-HSD) in the supernatant by immunofluorescence staining.

RESULTSAfter induction, the BMSCs of groups B, C, D, and E exhibited microscopic features of enlarged size, inter-connection, long-shuttle or irregular shape, adherent growth, and large round nuclei, all characteristic of Leydig cells. With the prolonging of time and enhanced concentration of bFGF, gradual increases were observed in the T level and the count of 3β-HSD-positive BMSCs in the four induction groups, with statistically significant differences between group B and groups C, D, and E (P < 0.05), as well as between group C and groups D and E (P < 0.05), but not between D and E (P > 0.05).

CONCLUSIONThe bFGF has an obvious promoting effect in the in vitro induced differentiation of rat BMSCs into Leydig cells.

OBJECTIVETo study clinical efficacy of smoothing Gan reinforcing Shen (SGRS) method in treating poor response of diminished ovarian reserve (DOR) patients in in vitro fertilization and embryo, transfer (IVF-ET).

METHODSTotally 84 DOR patients undergoing IVF-ET were assigned to the experimental group (SGRS Chinese herbs as adjuvant therapy) and the control group according to random digit table, 42 in each group. Patients in the control group received controlled ovarian hyperstimulation (COH) and IVF-ET. Those in the experimental group additionally received basic formula of SGRS method, one dose per day. The dose and use time of recombinant follicle-stimulating hormone (r-FSH) were recorded during ovarian stimulation process. On the injection day of human chorionic gonadotropin (HCG) and serum levels of estradiol (E2) on the oocyte retrieval day were determined using chemiluminescent method. E2 contents in the follicular fluid on the oocyte retrieval day were detected using ELISA. The total number of retrieved oocytes, the number of mature oocytes in metaphase II (M II), the number of normal fertilization [with two pronucleus (2PN)], the number of portable embryos, and the number of good quality embryos were recorded. The correlation between Chinese medical adjuvant therapy and the aforesaid indices were observed. The clinical pregnancy rate and the abortion rate were finally compared between the two groups.

RESULTSThe total dose of r-FSH, the E2 level on HCG injection day, the serum E2 level on the oocyte retrieval day, the number of retrieved oocyte, the number of oocytes in M II the number of oocytes with 2PN, the number of portable embryos, and the number of good quality embryos were all positively correlated with Chinese medical adjuvant therapy (P < 0.05, P < 0.01). Compared with the control group, serum E2 levels on the HCG injection day and the oocyte retrieval day obviously increased, the number of retrieved oocytes, the number of oocytes in M II, and the number of portable embryos were increased more in the experimental group with statistical difference (P < 0.05, P < 0.01). There was no statistical significance in the clinical pregnancy rate or the abortion rate between the two groups (P > 0.05).

CONCLUSIONSGRS Chinese herbs as adjuvant therapy could improve ovarian responsiveness of DOR patients undergoing IVF-ET, increase the number of retrieved oocytes, elevate the quality of oocytes and the number of embryos.

OBJECTIVETo explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

METHODSOne hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups.

RESULTSThe PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05).

CONCLUSIONWarm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.

OBJECTIVETo evaluate the efficiency of first trimester prenatal screening for fetal chromosome abnormality using maternal serum marker test and(or) plus nuchal translucency (NT) in Guangzhou region.

METHODSThe results of prenatal screening were retrospectively analyzed among 43 703 women with singleton pregnancies from January 2007 to September 2012. A total of 43 703 pregnancies between 9 and 13(+6) weeks of pregnancy were collected and analyzed for maternal serum pregnancy-associated plasma protein A (PAPPA), free β -human chorionic gonadotropin (free β -hCG) with or without crown-rump length (CRL). Nuchal translucency was measured by ultrasonographic scan between 11 and 13(+6) weeks of pregnancy. Gestational age was estimated by ultrasonographic scan. The risk values of Down syndrome (DS) and trisomy 18 were calculated using the software Lifcycle. Comparing the difference between the combined screening (PAPPA, free β -hCG and NT) and serum marker screening (PAPPA and free β -hCG).

RESULTSAmong the 43 703 pregnant women, screening showed that 1385 (3.17%) were Down syndrome positive and 55 (0.13%) were trisomy 18 positive. The final outcomes of pregnancy showed that 142 cases presented chromosomal abnormalities, of which 54 cases suffered from Down syndrome, 13 had trisomy 18, and 75 had other chromosome abnormalities. The total detection rate of Down syndrome and trisomy 18 were 83.33% and 76.92%, respectively.The positive rate is lower, and the detection rate is higher in combined screening group than serum marker screening group. The median PAPPA MoM was lower and the median free β -hCG MoM and NT measured value was higher in Down syndrome pregnancies than control group. The median PAPPA and free β -hCG MoM were lower and the median NT measured value was higher in trisomy 18 pregnancies than control group.

CONCLUSIONThe first trimester prenatal screening can effectively detect Down syndrome and trisomy 18 pregnancy. The combined screening method is superior to the serum marker screening and is the preferred strategy in the first trimester prenatal screening.

A variety of biomarkers have been identified in recent prospective and retrospective reports as being potentially predictive of venous thromboembolis (VTE), particularly idiopathic deep venous thrombosis (IDVT). This study identified a serum tumor biomarker for early screening of IDVT. A total of 128 IDVT patients (54 females and 74 males; average age: 50.9±17.4 years) were included. Carcinoembryonic antigen (CEA), ferritin, β2-microglobulin, cancer antigen (CA) 125, CA 15-3, CA 19-9, squamous cell carcinoma antigen (SCC), alpha-fetoprotein (AFP), prostate specific antigen (PSA), free PSA (f-PSA), and beta-human chorionic gonadotropin (β-HCG) in patients with IDVT were detected. Malignancies were histo- or cytopathologically confirmed. Of the 128 IDVT patients, 16 (12.5%) were found to have malignancies. Serum CEA, CA 125, CA 15-3, and CA 19-9 were found to be helpful for detecting malignancies in IDVT patients. Our study revealed a positive association between these markers and tumors in IDVT patients. On the other hand, SCC and AFP were not sensitive enough to be markers for detecting tumors in patients with IDVT. No significant differences were found in positive rates of ferritin and β2-microglobulin between tumor and non-tumor groups, and no significant difference exists in serum levels of ferritin and β2-microglobulin between the two groups. Carbohydrate antigens, CA 15-3 in particular, may be useful for differential diagnosis and prediction of malignancies in patients with IDVT.
