Objective To assess the 25-hydroxyvitamin D (25-OH-D) and interleukin-17(IL-17) status in patients with systemic lupus erythematosus(SLE) and its clinical significance. Methods 40 SLE patients along with 20 matched controls were collected. Chemilumineseent immunoassay (CLIA) was used to detect the levers of serum 25-OH-D. The levels of serum IL-17 were evaluated using enzyme-linked immunosorbent assay (ELISA). Results Serum 25-OH-D level in SLE patients was significantly lower than in healthy controls (P<0.01). Serum 25-OH-D level in active SLE patients was significantly lower than in inactive SLE patients (P<0.01). Lever of IL-17 was significantly higher in SLE patients than in healthy controls (P<0.01). Insufficiency of 25-OH-D was related to renal disorders. Serum 25-OH-D level was negatively correlated with systemic lupus erythematosus disease activity index (SLEDAI) scores(r=-0.844, P<0.01)and serum levels of IL-17(r=-0.596, P<0.01). Conclusion Insufficiency of 25-OH-D is prevalent in SLE patients. It is associated with nephritis, disease activity and high serum levels of IL-17, thus it may play an important part in the inflammatory process in SLE.

Methods HX43 was sequenced by the Illumina Miseq platform, and sequencing data were analyzed by the Edena, RAST, ResFinder, MLST and BLAST softwares and databases. Results HX43 was resistant to most common clinical antibiotics except carbapenems. Analysis of data revealed resistance genes to β-lactams (bla_CMY-42, bla_CTX-M-14 and bla_OXA-30), aminoglycosides (aac(3)-IIa, aadA5, strA, strB and aac(6′)-Ib-cr), quinolones (aac(6′)-Ib-cr), trimethoprim/sulfonamides(sul1, sul2 and dfrA17), tetracyclines (tet(B)), chloramphenicol (catB3 and cmlA1), macrolides(erm(B) and mph(A)). Sequence analysis of the contig containing bla_CMY-42 identified correlations of the gene with ISEcp1 insertion sequences, blc and sugE genes. Plasmid typing identified 5 plasmid incompatibility groups in HX43. MLST analysis found that HX43 belonged to ST3835, a relatively rare sequence type in the world. Conclusion Information of resistance genes can be obtained by high-throughput sequencing, which provides important experimental data for clinical antimicrobial treatment.

Objective To investigate the clinical significance of combined detection of serum ferritin and high sensitive C reactive protein in patients with acute cerebral hemorrhage. Methods From January 2012 to December 2013, 77 cases with cerebral hemorrhage male 42, female 35; aged 45 to 82 year old, average age (67.19±10.17)years old. According to MRS(Modified Rankin Scale) score criteria, patients were divided into good prognosis group(group A) with MRS ≤2, and poor prognosis group (group B)with MRS ＞2. Another 35 cases of healthy physical examination were selected as the healthy control group(group C). RT(Routine blood test), Serum Ferritin(SF)and Hs-CRP were tested at the time of admission, the third, the seventh and the fourteenth day from onset of the disease respectively. Head CT were done at the time of admission, the third day from onset of the disease respectively. Neurological assessment were scored according to the NIHSS criteria(National Institutes of Health Stroke Scale) for the patients in the two groups at the time of admission and 12 months of follow up. Results 77 cases of cerebral hemorrhage were followed up for 12 months, 53 cases with MRS ≤2, the prognosis was good; And 24 cases with MRS >2, the prognosis was poor. The levels of Hs-CRP and SF were all higher in patients with cerebral hemorrhage than that in healthy control group (P<0.05) at the time of admission, the third day,seventh and fourteen day from onset of the disease respectively. The levels of Hs-CRP and SF were higher in group B than that in control group at the time of admission, the third day, the seventh day and the fourteenth day from onset of the disease respectively, but only at the time of admission, three days from onset of the disease, the difference was statistically significant (P<0.05). At the same time, the brain edema and edema index in the group B were higher than those in group A. The independent risk factors influencing the prognosis of cerebral hemorrhage were NIHSS score (P=0.012), Hs-CRP(P=0.027) and SF(P=0.041). Conclusion Hs-CRP and SF may be important indicators of the prognosis for cerebral hemorrhage in a certain degree.
