Objective To evaluate the therapeutic approach for patients with periampullary carcinoma (complicated) with acute cholangitis. Methods A comparative analysis of the clinical data of cases of (periampullary) carcinoma with acute cholangitis who were admitted and treated in our hospital during a 12-year period.They included 25 cases who underwent primary resection, and 12 cases who underwent a two-stage resection with initial bile duct drainge. Results After conservative procedures, the preoperative temperature and WBC of patients in primary resection group were much lower than when admitted(P0.05). Total bilirubin and albumin levels showed no significant changes. Compared with the two-stage resection group,the primary resection group had shorter preoperative preparation time, shorter operation time, lesser intra-operative blood loss, but higher postoperative infection complication rate and prolonged length of hospital stay(P0.05). Conclusions Patients with periampullary carcinoma complicated with acute cholangitis can initially be treated conservatively . After biliary infection is controlled, primary (pancreatoduodenectomy) is performed.

It is a trend that clinical researchers overemphasize on hypothesis testing and the P value. However, P value has some limitations in the presentation of study results. Power is a tool for study design and results explanation, especially for negative results. Confidence interval contains more information for clinical results than P value. P value, power, and 95% confidence interval should be provided in the clinical reports to facilitate the interpretation of the results.

Ahigh-resolutionmethodforhumanleukocyteantigen-B(HLA-B)genotypingwasestablished based on the optimized polymerase chain reaction, cloning and sequencing technology. The exon2 and exon3 of HLA-B gene were amplified with primers based on the HLA-B gene sequence. These produced heterozygous alleles were effectively cloned into plasmid DNA based on the principle of plasmid incompatibility, and were followed by bacterial culture. Then Sanger sequencing was carried out and after analyzing the result by software ClustalX2 and IMTG/HLA database comparison, the HLA-B genotype of the samples was achieved. Seven clinical samples were detected, and the results were consistent with those of PCR-SBT genotyping method. The method was cost-effective, high-resolution and it did not require technical software. The use of universal primers simplified the cumbersome design and optimization process of specific primers.

Objective To observe functional changes of renal tubular epithelial cells stimulated by high mobility group protein box 1 (HMGB1) and associated mechanism.Methods Renal tubular epithelial cells (NRK52E) were divided into control group,HMGB1 group and HMGB1+ lipopolysaccharide from Rhodobactersphaeroides (LPS RS) group.Toll-like receptor 4 (TLR4) expression was detected by immunofluorescence and Western blotting.Apoptosis rate and cell cycle arrest were identified with flow cytometry.The activation of MAPK signaling pathway and NF-κB were detected by Western blotting.The IL-1,IL-6 and tissue inhibitor of metalloproteinases 2 (TIMP2) mRNA levels were measured by real-time PCR.The secretion levels of IL-1,IL-6 and TIMP2 were measured by protein chips assay.Results TLR4 was expressed by NRK52E cells.Compared with the control group,there were increased cell cycle G1 arrest,MAPK signaling pathway and NF-κB activation in HMGB1 group.Furthermore,IL-1,IL-6 and TIMP2 mRNA levels were increased and IL-1,IL-6 and TIMP2 were secreted by NRK52E when stimulated with HMGB1 (all P ＜0.05).However,effects mediated by HMGB1 stimulation could be inhibited by LPS RS (all P＜0.05).Conclusions Inflammatory activation of NRK52E cells can be mediated by the interaction of HMGB1 and TLR4.
