BACKGROUND Porphyria is a rare disease with complex classification. Erythropoietic protoporphyria(EPP) is an autosomal recessively inherited disease, and most are caused by mutations in the FECH gene. EPP combined with liver injury is even *** SUMMARY This paper reports a case of EPP which was admitted to the hospital with abnormal liver function and diagnosed by repeated questioning of medical history, screening of common causes of severe liver injury, and second generation sequencing of the whole exon genome. We also summarize the clinical characteristics of EPP with liver injury, and put forward some suggestions on EPP to provide a reference for the diagnosis of such rare *** A new mutation locus(c.32_35 dupCCCT) which may be related to the disease was found by detecting the FECH gene in the pedigree of this case.

Objective To study whether Lycium barbarurn glycopeplide 3 （LBGP3） affects T cell apoptosis in aged mice. Methods LBGP3 was purified with DEAE cellulose and Sephadex columns. Apoptotic ＂sub-G1 peak＂ was detected by flow cytometry and DNA ladder was resolved by agarose gel electrophoresis. Levels of IFN-7 and IL-10 were measured with specific kits and mRNA expression was detected by RT-PCR. Apoptosis-related proteins of FLIP, FasL, and Bcl-2 were determined by Western blotting. Results LBGP3 was purified from Fructus Lycii water extracts and identified as a 41 kD glycopeptide. Treatment with 200 p.g/mL LBGP3 increased the apoptotic rate of T cells from aged mice and showed a similar DNA ladder pattern to that in young T cells. The reversal of apoptotic resistance was involved in down-regulating the expression of Bcl-2 and FLIP, and up-regulating the expression of FasL. Conclusion Lycium barbarum glycopeptide 3 reverses apoptotic resistance of aged T cells by modulating the expression of apoptosis-related molecules.

BACKGROUND: Acute-on-chronic liver failure(ACLF) is a severe clinical syndrome that may cause a high mortality. However, the mechanism is still not clear. Characterization of the microRNA(miRNA) profiles in ACLF patients may provide new clues to the pathogenesis and management of this syndrome. METHODS: Genome-wide microarray was performed to compare the different miRNA expression profiles in peripheral blood mononuclear cells of a pair of monozygotic twins, an ACLF patient and an HBV asymptomatic carrier(AsC). The case-control miRNA profiles were compared and confirmed by quantitative reverse transcription-polymerase chain reaction in 104 ACLF patients and 96 AsCs. A combined computational prediction algorithm was used to predict the potential target genes. RESULTS: Forty-five miRNAs were increased and eight miRNAs were decreased in the ACLF group. The expressions of hsa-let-7a and hsa-miR-16 were increased by 8.58- and 8.63-fold in ACLF patients compared with that in AsCs, respectively(P<0.001). CARD8, BCL2, IL1RAPL1, LTB, FZD10 and EDA were identified as the target genes of hsa-miR-16; MAP4K3, OPRM1, IGF2BP1 and CERCAM were verified as the target genes of hsa-let-7a. CONCLUSIONS: Our results showed that there is a close relationship between specific miRNAs of peripheral blood mononuclear cells and ACLF. hsa-miR-16 and hsa-let-7a may contribute to the development of ACLF.

BACKGROUND：The current methods used for diagnosing hepatocellular carcinoma（HCC）are ***,we assessed the serum levels of secreted frizzled related protein 4（s FRP-4）for diagnosing HCC in patients infected with chronic hepatitis B（CHB）.METHODS：In 272 patients with CHB enrolled,142 were pa tients with ***-three healthy subjects were recruited as healthy *** CHB patients were assigned to a test group or a validation group based on the time of enrollment. Human antibody arrays were used to screen 15 patients （8 CHB-related HCC patients, 7 CHB patients） for serum mark- ers. Four markers and one candidate marker were assessed in the test group and validation group, respectively. RESULTS： Human antibody assays indicated that the serum levels of sFRP-4 in HCC patients were significantly higher than those in CHB patients （P〈0,05）. Additionally, serum sFRP-4 levels were significantly higher in the HCC patients than those in the non-HCC patients in both test group （79.7 vs 41.3 ng/mL; P〈0.001） and validation group （89.0 vs 39.0 ng/mL; P〈0.001）. Areas under the Receiver Operating Charac- teristic curves （AUCs） for alpha-fetoprotein （AFP） and sFRP-4 were similar in both test group and validation group. In the test group, the combination of sFRP-4 （a sensitivity of 94.4%, a specificity of 60.5% at 46.4 ng/mL） and AFP （a sensitivity of 75.0%, a specificity of 87.2% at 11.3 ng/mL） showed better performance for diagnosing HCC （a sensitivity of 79.2% and a specificity of 95.3%）. The AUC for combined sFRP-4 and AFP increased to 0.941 （95% CI： 0.908-0.975）, and similar results were seen in the validation group. CONCLUSION： sFRP-4 is a candidate serum marker for diagnosing HCC in CHB patients, and the combination of sFRP-4 with AFP may improve the diagnostic accuracy of HCC.
