RESUMO

PURPOSE: ZFP36 ring finger protein (ZFP36) and the suppressor of cytokine signaling 3 (SOCS3) have been reported to, respectively, regulate NF-κB and STAT3 signaling pathways. To better understand the correlation of NF-κB and STAT3 negative regulates pathway, we have investigated the involvement of ZFP36 and SOCS3 expressions in human prostate cancer (PCa). METHODS: In the present study, paired patient tissue microarrays were analyzed by immunohistochemistry, and the ZFP36 protein expression was quantitated as immunoreactive scores in patients with PCa. Associations between ZFP36/SOCS3 expression and various clinicopathological features and prognosis of PCa patients were statistically analyzed based on the Taylor database. Then, the functions of ZFP36 and SOCS3 in cancerous inflammation were determined using qPCR and immunohistochemistry in vitro and in vivo. RESULTS: ZFP36 protein expression in PCa tissues was significantly lower than those in non-cancerous prostate tissues (P < 0.05). In mRNA level, ZFP36 and SOCS3 had a close correlation with each other (P < 0.01, Pearson r = 0.848), and its upregulation was both significantly associated with low Gleason score (P < 0.001 and P < 0.001, respectively), negative metastasis (P < 0.001 and P < 0.001, respectively), favorable overall survival (P < 0.001 and P < 0.05, respectively), and negative biochemical recurrence (P < 0.001 and P < 0.001, respectively). Functionally, LPS treatment could lead to the overexpression of ZFP36 and SOCS3 in vitro and vivo. CONCLUSIONS: Our data offer the convincing evidence for the first time that the aberrant expressions of ZFP36 and SOCS3 may be involved into the progression and patients' prognosis of PCa, implying their potentials as candidate markers of this cancer.

RESUMO

FUT1 and TAP1 have been identified as candidate genes that offer resistance against Escherichia coli F18 infection, with the AA genotype in FUT1 and the GG genotype in TAP1 conferring resistance. In order to confirm polymorphisms at FUT1 M307 and TAP1 G729, and evaluate their influence on immunity performance in Pudong White pigs, we performed polymerase chain reaction-restriction fragment length polymorphism analysis, measured immune indices, and compared the results with those observed in Large White pigs. The AA genotype of FUT1 was first discovered in Pudong White pigs and has not been found in other Chinese domestic pig breeds. The frequency of the AA genotype in Pudong White and Large White pigs was 0.018 and 0.052, respectively. The GG genotype of TAP1 was also detected in the two breeds, with a frequency of 0.708 and 0.695, respectively. Chi-square fitness analysis of both genes showed that these loci deviated from Hardy-Weinberg equilibrium in the two breeds (P < 0.05). No significant differences were observed in interleukin-6 (IL-6) and IL-10 levels among the three genotypes at FUT1 and TAP1 in the two breeds (P > 0.05). Individuals for all genotypes of TAP1 in both pig breeds had similar TNF-α levels (P > 0.05), implying that Pudong White pigs may have the same ability for hepatocyte inflammatory response and B cell differentiation as Large White pigs. These differences have a degree of influence on Pudong White pig's immune ability to resist F18 or other infections.

RESUMO

The present study investigates the effects of electroacupuncture (EA) on urinary bladder pressure (UBP) in patients with acute gastrointestinal injury (AGI). Twenty patients with AGI admitted to the First Hospital of Jiaxing intensive care unit from December 2011 to June 2013 were evaluated. Conventional group patients (n = 10) were administered moderate enteral nutritional support, and electroacupuncture group patients (n = 10) were administered enteral nutritional support followed by EA at bilateral Zusanli (ST-36), Shangjuxu (ST-37), Hegu (LI-4), and QuChi (LI-11) acupoints. UBP was then measured every 6 h and the serum creatinine once daily for 7 days. There were no statistically significant patient demographic differences in the study groups (P > 0.05). The initial UBP of both patient groups was ≥12 mmHg. On days 6 and 7, the UBP significantly decreased in the EA group compared to the conventional group (P < 0.05). The serum creatinine concentration on day 7 was significantly lower in the EA group than in the conventional group (P < 0.05). Based on these results, electroacupuncture contributed to gastrointestinal motility recovery in patients with AGI. This procedure may reduce UBP and provide organ-protective effects in AGI patients.
