Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

Cucumber mosaic virus was detected from infected Basella rubra L. with the indirect enzyme-linked immunosorbent assay. Total RNA was extracted from infected leaves and the cDNAs of coat protein gene of CMV-Ba were obtained by RT-PCR. The amplified cDNA fragments were then cloned into pMD 18-T vector and sequenced,the result showed that the CP gene was 657 nucleotides in length. This sequence was aligned with the obtained CP gene and some CMV strains or isolates of subgroup Ⅰ and subgroup Ⅱ in GenBank using DNA MAN software. The results showed that CMV-Ba shared 90.9%~93.8% and 76.1%~76.9% identity with the known CP genes of subgroup Ⅰ and Ⅱ respectively in nucleotide level,on the other hand,amino acids deduced from CMV-Ba CP gene shared 92.7%~97.7% and 72.4%~78.1% identity with the known CP protein of subgroup Ⅰ and Ⅱ,respectively. This suggested that CMV-Ba CP gene belongs to CMV subgroupⅠ.

ObjectiveTo discuss the characters and management of renal lymphangiectasia.MethodsThe clinical data of two cases of renal lymphangiectasia were reviewed. The first patient was a 37-year-old woman with the chief complaint of lumbago in the right flank for 8 days.B-ultrasound showed mixed echo in perinephric space. On CT, similar appearances of fluid collections were seen, but not conspicuous. Conservative treatment was taken for three weeks and the symptoms were relieved. Three month later the patient had right lumbago relapse. CT scan revealed a large amount of fluid collection under the capsule of the right kidney. Percutaneous drainage was carried out. Two months later B-ultrasound showed fluid collection in perinephric space and percutaneous drainage again the fluid was sent to pathology. The second case was a 32-year-old woman with the chief complaint of lumbago in the left flank for the past three years. Ultrasonography revealed hyperechoic surrounding the left kidney. CT scan showed a left perinephric collection of fluid attenuation and circumferentially draping around the kidney. Renal lymphangioma was diagnosed and the patient underwent surgery.ResultsNeedle aspiration of the perinephric fluid was carried out, and laboratory analysis showed most leucocytes were lymphocytes. The pathologic diagnosis of the first case was renal lymphangiectasia. There was no recurrence during follow - up of two months. The second case was diagnosed renal lymphangioma pathologically. Follow - up for nine years, revealed no relapse.ConclusionsUltrasonography and CT contributed to the diagnosis of renal lymphangiectasia. Needle aspiration bioposy and histology could confirm it. Treatment of asymptomatic cases is not required. When collections are very large and cause symptoms, percutaneous drainage may be carried out however there is a risk of relapse.

Objective To investigated the effect of TangNaiKang (TNK) on VEGF protein expression of GK rats Thoracic aorta. Methods 51 male GK rats were divided into five groups randomly: model group, pioglitazone group, and TNK treatment group (low, immediate and high dose). Another 10 male Wistar rats were served as normal control group. GK rats were fed with high-grease forage, while normal control group was fed with a standard diet. Fasting blood glucose, general HE staining and VEGF protein expression were detected by immunohistochemistry. Results The fasting glucose had a significant decline in TNK treatment groups. HE staining showing TNK can ameliorate intima thickness, reduce hyperplasia of shallow vascular smooth muscle cell, and improve wavy and plexiform arrangement of elastic lamina. Immunohistochemistry also showed that TNK decreased VEGF protein expression of great vessels. Conclusion TangNaiKang can prevent and cure diabetic vascular complication of GK rats.

OBJECTIVETo investigate the expression of the Pim-1 gene in the LNCaP cells of the animal model of orthotopically implanted prostate cancer by surgical castration simulating androgen-deprivation therapy.

METHODSWe equally allocated 32 male BALBc-nu mice into 4 groups, androgen-dependent prostate cancer (ADPC), androgen-deprivation therapy (ADT) , castration-resistant prostate cancer (CRPC) and blank control, and established the models of orthotopically implanted tumor using human prostate cancer LNCaP cells. We detected and ,compared the expressions of Pim-1, PSA, and androgen receptor (AR) in the tumor tissues of different groups by RT-PCR. qRT-PCR, ELSIA and immunohistochemistry.

RESULTSThe relative gray scales in the ADPC and CRPC groups were 0.59 ± 0.01 and 1.14 ± 0.02, with statistically significant differences from 0.62 ± 0.03 in the ADT group (P < 0.05), and the Δ Ct values of Pim-1 were 6.15 ± 0.34 and 4.56 ± 0.23 in the former two groups, also with significant differences from 5.11 ± 0.21 in the latter (P < 0.05). The results of 2-ΔΔ Ct relative quantification analysis showed that the amplification products of Pim-1 in the ADT and CRPC groups increased 2.05 and 3.01 times respectively that of the ADPC group. The concentration of PSA was significantly higher in the ADPC ([480 ± 25] pg/ml) and CRPC ([870 ± 23] pg/ml) than in the ADT ([170 ± 32] pg/ml) and blank control groups (0 µg/L) (P < 0.01). The mean optical densities of Pim-1 and AR proteins were 0.017 ± 0.002 and 0.032 ± 0.009 in the ADPC group and 0.024 ± 0.002 and 0.040 ± 0.011 in the CRPC group, both with significant differences from those in the ADT group (0.018 ± 0.001 and 0.019 ± 0.006) (P < 0.01).

CONCLUSIONPim-1 is highly expressed in nude mice with prostate cancer receiving androgen-deprivation therapy and plays an important role in the progression and metastasis of prostate cancer.

OBJECTIVETo compare the effect of transumbilical single-site single-port with that of transumbilical single-site double-port laparoscopic varicocelectomy in the treatment of varicocele in adolescents.

METHODSWe randomly assigned 80 varicocele patients aged 10 - 16 years to two groups of equal number to receive transumbilical single-site single-port and single-site double-port laparoscopic varicocelectomy, respectively. We compared the operation time, postoperative hospital stay, incisional pain, complications and satisfaction with the abdominal cosmetic outcomes between the two groups.

RESULTSAll the operations were successfully performed. The double-port group showed a significantly higher score on the Visual Analogue Scale than the single-port group (4.8 +/- 1.4 vs 3.6 +/- 1.1, t = -4.986, P < 0.01), but there were no significant differences between the two groups in the operation time ([29.8 +/- 4.2] vs [31.2 +/- 4.6] min, t = 1.383, P = 0.171), postoperative hospital stay ([1.95 +/- 0.7] vs [1.82 +/- 0.8] d, t = -0.784, P = 0.436), complications (0 vs 0) and scores on the satisfaction with abdominal cosmetic outcomes (4.6 +/- 0.6 vs 4.8 +/- 0.5, t = 1.253, P = 0.214). No recurrence, umbilical hernia, hydrocele and orchiatrophy were found in the two groups of patients at 6 months after operation, and no visible scar was observed on the abdominal surface.

CONCLUSIONWith strict surgical indications, single-site single-port and single-site double-port laparoscopic varicocelectomies have similar clinical effects in the treatment of varicocele, which leave no scar on the abdominal surface. Single-site double-port laparoscopy needs no special instruments and therefore is worthier of wide clinical application.
