ObjectiveTo investigate the expressions of folate receptor alpha (FOLR1) in 40 esophageal cancerous tissues and its relevance of ABO blood group.MethodsABO blood groups were analyzed in 40 patients.Immunohistochemistry (IHC) and real-time quantitative reverse transcription PCR detection were used to detect the expression of folate receptor in cancer and adjacent tissues.Results20%of esophageal cancer was suspected positive (+), 50% of cancer adjacent tissue was suspected positive (+), 10% were positive (+), the difference was statistically significant (x2 = 14.48, P <0.01).Real Time RT-PCR analysis showed FOLRI low expression in esophageal cancer and adjacent tissues, compared to normal esophageal mucosa, the differences were statistically significant (F1 =53.247, F2 = 116.500, P <0.01).ABO blood type and FOLRi in esophageal cancer patients were not significant correlated (P =0.647, P >0.05).ConclusionsFOLRI expression was decreased in the esophageal lesions compared with adjacent tissues.Detection of FOLRl expression level in esophageal cancerous tissues and the paired adjacent tissues was helpful for judging the extent of disease and guiding surgery treatment.The FOLRI expression level in esophageal carcinoma tissues had no relationship with ABO blood types.

Objective: To study the CT features and its diagnosis of spontaneous renal vein shunt (SPVA) in portal hypertension. Methods: Totally 220 cirrhosis patients with portal hypertension diagnosed clinically underwent multi-slice CT scanning. The parameters were 5 mm/6. 5 mm/2. 0 mm(collimation/effective thickness/interval) in 180 patients and 2. 5 mm/3. 2 mm/1. 6 mm in 40 patients. An arterial-phase (delaying 26-28 s) and a portal venous phase (55-60 s) were included. All images were showed by cine and CTA was displayed with volume rendering and thin-slab maximum projection when ah normal vessels were suspected. Results: The spontaneous renal shunt were found in 26 patients (11. 8%), including spleno left renal shunt(20 patients), gastro-left renal shunt (16 patients), and portal-right renal shunt(2 patients). The veins sur rounding renal hilum were rich and thick in 7 patients. Conclusion: The SPVA is not rare in portal hypertension, enhanced CT scan and angiography with multi-slice CT can effectively display the shunt vessels, contributing to the correct diagnosis and right therapy.

Objective To establish a dual real-time fluorescence quantitative polymerase chain reaction (dual real-time PCR) assay to detect human vitamin D receptor (VDR) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Methods GAPDH gene was used as the internal control. The specific primers and TaqMan probes were designed by Primer Premier 5.0 software, which were applied to detect the VDR/GAPDH mRNA levels. The obtained PCR products were puri-fied to construct the VDR/GAPDH recombinant plasmid, which was taken as the standard to analyze the sensitivity and re-peatability of the method. Results The amplification products were confirmed as the specific fragment of VDR/GAPDH by DNA sequencing instrument. The results showed that the sensitivity, linear range, the determinate coefficient, the amplifica-tion efficiency, the intra-assay and inter-assay coefficient of variation were 40 copies/μL, 4.00 × 101-4.00 × 105 copies/μL, 0.998, 96.10%, 0.09%-1.21%, 0.17%-0.51%for VDR, and 40 copies/μL, 4.00 × 101-4.00 × 105 copies/μL, 0.999, 85.15%, 0.35%-0.88%, 0.51%-2.46% for GAPDH, respectively. Conclusion These results demonstrate that the dual real-time PCR assay with high sensitivity and specificity can detect the relative expressions of human VDR by single reaction tube, which can effectively shorten the time and reduce the experimental error.
