The aim of this study was to investigate the effect of platelet-rich plasma (PRP) on cavernous nerve (CN) regeneration and functional status in a nerve-crush rat model. Twenty-four Sprague-Dawley male rats were randomly divided into three equal groups: eight had a sham operation, eight underwent bilateral nerve crushing with no further intervention and eight underwent bilateral nerve crushing with an immediate application of PRP on the site of injury. Erectile function was assessed by CN electrostimulation at 3 months and nerve regeneration was assessed by toluidine blue staining of CN and nicotinamide adenine dinucleotide phosphate (NADPH)-diaphorase staining of penile tissue. Three months after surgery, in the group that underwent bilateral nerve crushing with no further intervention, the functional evaluation showed a lower mean maximal intracavernous pressure (ICP) and maximal ICP per mean arterial pressure (MAP) with CN stimulation than those in the sham group. In the group with an immediate application of PRP, the mean maximal ICP and maximal ICP/MAP were significantly higher than those in the injured control group. Histologically, the group with the application of PRP had more myelinated axons of CNs and more NADPH-diaphorase-positive nerve fibres than the injured control group but fewer than the sham group. These results show that the application of PRP to the site of CN-crush injury facilitates nerve regeneration and recovery of erectile function. Our research indicates that clinical application of PRP has potential repairing effect on CN and peripheral nerves.

LRP16 is a novel gene which was found in our laboratory by using methylation-sensitive restriction landmark genomic scanning (RLGS) technique. In order to clone the full-length cDNA of this leukemia relapse associated gene, the method of rapid amplification of cDNA end (RACE) was employed. By optimizing some procedures of RACE method, the 5'- and 3'-untranslated region of LRP16 cDNA was successfully sequenced. Then, the full length of LRP16 cDNA and open reading frame (ORF) was constructed and was registered in GenBank. The above-mentioned procedure demonstrated RACE technique is a rapid and sensitive method for cloning unknown gene. Especially, it is very useful to cloning the 5'- and 3'-untranslated region of a novel gene.

OBJECTIVETo investigate the levels of pro-inflammatory cytokine IFN-gamma and anti-inflammatory cytokine TGF-beta1, in the expressed prostatic secretion (EPS) of men with chronic abacterial prostatitis and their clinical significance.

METHODSThe levels of IFN-gamma and TGF-beta1, in the EPS of 20 patients with inflammatory chronic pelvic pain syndrome (type III A), 20 patients with non-inflammatory chronic pelvic pain syndrome (type Ill B) and 10 healthy men were measured using enzyme-linked immunosorbent assay (ELISA). The results were analysed comparatively with NIH-chronic prostatitis symptom index (NIH-CPSI).

RESULTSIFN--gamma and TGF-beta1 levels were higher in III ([14.92 +/- 7. 85)], [8477.50 +/- 4612.45] ng/L) and III B ([13.74 +/- 5.96], [7946.50 +/- 5044.06] ng/L) prostatitis patients than those in the controls ([7.47 +/- 1.49], [2462.50 +/- 985.31] ng/L), P < 0.05 and P < 0.001 respectively. There was no statistically significant difference in cytokine levels between III A and Il B prostatitis patients. No correlation was found between NIH-CPSI and cytokine levels, r = 0.02, P = 0.86, r = 0.31, P = 0.76.

CONCLUSIONIFN-gamma and TGF-beta1, play a very important role in the etiology of chronic abacterial prostatitis and can be the objective parameters in the diagnosis of chronic abacterial prostatitis.

OBJECTIVETo study the relationship between the patatin-like phospholipase domain-containing protein 3 (PNPLA3) gene and hereditary susceptibility to non-alcoholic fatty liver disease (NAFLD) by detecting single nucleotide polymorphisms (SNPs).

METHODSPeripheral blood DNA from 315 patients diagnosed with NAFLD (including the spectrum of simple steatosis (SS) and non-alcoholic steatosis (NASH)) and 336 control subjects was used to determine the PNPLA3 genotype by polymerase chain reaction (PCR) and direct sequencing. The relationship of SNPs and NAFLD-related markers of liver function were assessed by correlation analysis.

RESULTSThe SNP rs738409 was identified in more of the NAFLD patients (allele variant frequencies: NAFLD, 65.40%; NASH: 71.87%; SS, 56.47%) than in the controls (33.18%). Case-control analysis revealed that carriers of the 148GG genotype were at 3.81-fold (95% CI: 3.03 ~ 4.79) higher risk of developing NAFLD and at 1.97-fold (95% CI: 1.41 ~ 2.75) higher risk of progressing from SS to NASH, compared with non-carriers. rs738409 was also found to be associated with serum levels of alanine aminotransferase (ALT) and y-glutamyltransferase (y-GT) (both P less than 0.05). Carriers of the 148GG genotype had significantly higher body mass index, ALT, and fasting insulin than carriers of the 148CC genotype (all P less than 0.05), and significantly higher level of serum HDL than carriers of either the 148CC genotype or the 148GC genotype (both P less than 0.05).

CONCLUSIONPolymorphisms in the PNPLA3 gene may play an important role in mediating susceptibility to developing NAFLD in the Chinese population. The rs738409 polymorphism, in particular, is related to development and progression of NAFLD and may play a role in the contribution of PNPLA3 to NAFLD pathogenesis.

OBJECTIVETo investigate the rule of lymph node metastasis in colorectal cancer and its affecting factors, and to provide clues for clinical diagnosis and treatment of colorectal cancer patients.

METHODSThe clinical data of 1166 cases of colorectal cancer receiving surgical resection were analyzed retrospectively.The relationships between clinicopathologic variables and lymph node metastases were evaluated by crosstabs and logistic regression in SPSS 10.0 for windows.

RESULTSThe rate of lymph node metastasis in colorectal cancer was 49.7%. After entering crosstabs estimation, gender and tumor site were not significantly correlated with lymph node metastasis in colorectal cancer(chi2=1.46, r=0.035, P>0.05 and chi2=3.86, r=0.012, P>0.05). Age, tumor size, the massive type of the tumor, the differentiating degree of the tumor, histology type and the depth of tumor invasion were proved to be independent factors influencing the lymph node metastasis in colorectal cancer (chi2 =13.1, r=0.064, P<0.05 and chi2=77.161, r=0.245, P<0.01 and chi2=144.831, r=0.341, P<0.01 and chi2=128.310, r=0.318, P<0.01 and chi2=120.418, r=0.319, P<0.01 and chi2=227.287, r=0.434, P<0.01). After entering logistic regression estimation, the correlativity of risk factor of lymph node metastasis in colorectal cancer: the depth of tumor invasion > the massive type of the tumor>the differentiating degree of the tumor > tumor size. Preoperative blood serum CEA level was significantly correlated with lymph node metastasis (chi2=509.599, r=0.661, P<0.01).

CONCLUSIONThe depth of tumor invasion is the most risk factor of lymph node metastasis in colorectal cancer. Preoperative high level of blood serum CEA indicates the occurrence of lymph node metastasis.
