OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

OBJECTIVETo study the expression of NPAS2 in colorectal cancer (CRC) and analyze its relationship with the clinicopathological parameters and prognosis of the patients.

METHODSReal-time q-PCR was used to detect the expression of NPAS2 mRNA in 40 fresh CRC tissues and paired adjacent tissues; immunohistochemistry was used to detect the expression of NPAS2 protein in 120 paraffin-embedded tumor and adjacent tissues. The relationship between NPAS2 expression level and the 5-year survival rate of 78 CRC patients with follow-up data were analyzed with Kaplan-Meier survival analysis.

RESULTSCompared with the adjacent tissues, fresh CRC tissue expressed significantly lower NPAS2 mRNA levels (P<0.01). Among the paraffin-embedded CRC tissues, 19.2% were positive for NPAS2 expression, as compared to a much higher rate of 62.5% in the adjacent tissues (P<0.05). The expression of NPAS2 was correlated with the tumor size, lymph node metastasis and TNM stages (P<0.05) but not with the patients' gender, age, distant tumor metastasis, differentiation, or invasion. Patients with high NPAS2 expression levels had a significantly higher 5-year survival rate than those with low NPAS2 expressions (P=0.0001).

CONCLUSIONNPAS2 is down-regulated in CRC and closely correlated with the malignant biological behavior of the tumor and 5-year survival of the patients, suggesting its value in predicting the prognosis of the CRC patients.
