Abstract: Objective　 This article aims to present a rare case of severe fever with thrombocytopenia syndrome (SFTS) complicated by with bacteraemia caused by Campylobacter jejuni, and to discuss the pathogenic characteristics, culture methods, clinical features and treatment points of Campylobacter jejuni and the patient's outcome, with a view to raising clinical awareness of blood culture and providing experience for the treatment of this disease. Methods　The clinical data of a case with SFTS complicated by bacteremia caused by Campylobacter jejuni admitted to Weihai Municipal Hospital were collected and the diagnostic process of the pathogenic bacteria as well as the treatment plan were retrospectively analysed. Results　The patient was a female who had been bitten by a tick bite half a month ago and presented to the hospital on 30th August with a fever, vague pain in the peribulbar abdomen and diarrhea for 5 days. Laboratory tests showed leukopenia and thrombocytopenia, and nucleic acid detection for SFTS was positive, resulting in a diagnosis of SFTS. After a week of antiviral treatment with ribavirin and symptomatic treatment, the patient suddenly experienced high fever at night, with a temperature reaching 39.5 °C. Blood cultures were immediately taken from both sides of the double bottle. Bilateral anaerobic bottles were tested for positive after 53.06 hours, and Gram-negative Campylobacter was cultured anaerobically in a transfer blood plate and further identified as Campylobacter jejuni using mass spectrometry MALDI-TOF MS. Vancomycin was stopped clinically on the basis of bacterial pathogenesis and meropenem was used for anti-infection and symptomatic treatment. During the treatment, blood culture and nucleic acid detection for SFTS turned negative, and the patient's symptoms improved. After normal results were achieved in the follow-up testing, the patient was discharged. Conclusions　This case serves as a reminder that Campylobacter jejuni not only causes intestinal infections, but can also lead to extra-intestinal infections in immunocompromised individuals. Clinical and laboratory personnel should increase their recognition of Campylobacter jejuni, prioritize blood culture methods, and utilize a multidisciplinary approach in diagnosis and treatment.

Objective:To investigate the protective effects of paeoniflorin on myocardial ischemia/reperfusion ( MI/R) injury in rats. Methods:The rat model of MI/R injury was prepared by coronary artery ligation for 30 min followed by 2-hour reperfusion. Then the rats were randomly divided into 5 groups:sham group, model group, paeoniflorin group respectively at high, medium and low dose (20, 10 and 5 mg·kg-1, n=10). Paeoniflorin was respectively injected via tail vein 1 h before the operation and at the beginning of the reperfusion. The CK, LDH and SOD activities and MDA contents in serum of rats were examined, and the area of myocardial in-farction was also calculated after the reperfusion. Results:Paeoniflorin (20 and 10 mg·kg-1 ) could significantly reduce the area of myocardial infarction when compared with the model group (P<0. 05). Paeoniflorin could obviously inhibit the CK and LDH activities (P<0. 05 or P<0. 01) and enhance the SOD activity (P<0. 01) in serum of MI/R rats. The MDA content in paeoniflorin groups at high and medium dose was significantly lower than that in the model group (P<0. 05). Conclusion:Paeoniflorin pretreatment shows effectiveness against MI/R injury, which may be associated with the inhibition of lipid peroxidation.

Objective To evaluate the relationship between children interleukin-1 receptor antagonist gene(IL-1RN) polymorphisms and susceptibility to febrile seizures(FS).Methods Matching case-control study was carried out,blood samples from 52 patients with FS and 53 healthy children were collected.Genomic DNA was extracted and examined by polymerase chain reaction(PCR) amplification for judging IL-1RN genetype.Results Only Ⅰ/Ⅰ,Ⅰ/Ⅱ,Ⅱ/Ⅳ genetypes of IL-1RN were found in the surveyed Chinese population of Han nationality in Guangdong Province.No significant differences of these genotypes were observed in patients and controls.But the allele frequencise of Ⅰ,Ⅱand Ⅳ in patients were 95.2%,3.8% and 1.0%,respectively,while these frequencise in controls were 84.9%,10.4% and 4.7%,respectively.The allele frequency of IL-1RNⅠin patients was obviously higher than that in controls(P

Objective To investigate the expression and prognostic significance of P-JAK2, P-STAT3 and mutant p53 in cervical lesions. Methods A total of 153 cervical biopsies of patients from Gynecology Department, The Second Hospital of Tianjin Medical University were recruited during December 2013 to June 2015. Fifty-seven cases of squamous carcinoma of cervix (SCC), 36 cases of low grade intraepithelial neoplasia (LSIL), 30 patients with high grade intraepithelial neoplasia (HSIL) and 30 cases of normal cervix (NC) were included in the study. Gene chip method was used to detect high-risk hu-man papillpmavirus(HR-HPV)infection. Hematoxylin-eosin staining was used to make pathological diagnosis. Immunohis-tochemical assay was used for the detection of P-JAK2, P-STAT3 and mutant type p53 protein expression in cervical le-sions. Results (1) HR-HPV infection rate and P-JAK2 expression were significantly higher in SCC group than those of HSIL group, LSIL group and NC group (P<0.05). (2) The expression of P-STAT3 and mutant type p53 were significantly higher in SCC group than those of LSIL group and NC group (P<0.05). However, there was no significant difference between SCC group and HSIL group. (3) The positive expressions of P-JAK2 and P-STAT3 showed significant differences in different FIGO stages, histopathological grade, lymph node metastasis and HR-HPV infection in SCC group, respectively ( P<0.05). There were significant differences in the positive expression of mutant type p53 between different FIGO stages and HR-HPV infection (P<0.05). (4) There was positive correlation between P-JAK2, P-STAT3, positive expression of mutant type p53 and HR-HPV infection in SCC tissues (P<0.05). There was a positive correlation between P-STAT3, p53 expression and HR-HPV infection (P<0.05). There was a positive correlation between mutant p53 expression and HR-HPV infection (P<0.05). Conclusion P-JAK2, P-STAT3 and mutant p53 protein expression rates are high in SCC group than those of NC and SIL groups, which may be associated with HR-HPV infection, cervical cancer occurrence and progression.

Objective To investigate the expression of MIF in PBMC, sera and lacrimal fluid samples in patients with AD, and study the diagnostic significance of MIF in AD. Methods Forty-three AD patients (11 mild AD patients,23 moderate AD patients, 9 severe AD patients classfied by SCORAD index)and 31 age- and sex-matched healthy control subjects were recruited. Real-time RT-PCR was employed to analyze the expression of MIF mRNA in PBMC. ELISA was performed to detect the concentrations of MIF in sera and lacrimal fluid samples. Results AD patients had significantly higher levels of MIF mRNA in PBMC than normal controls [7.46 (3.38-8.90) vs 1.67 ( 1.24-2.45 ), Z=-6.141, P ＜ 0.05]. The concentrations of MIF in sera and lacrimal fluid samples in AD patients were also markedly higher than those of normal controls [serum 36. 32( 11.89-43.80) μg/L vs 7.89(6.13-9.54) μg/L, Z = -6.180,P <0.05; lacrimal fluid 12.66(2.01-20.12) μg/L vs 0.85(0.77-1.06) μg/L, Z = -4.118,P <0.05]. MIF mRNA levels were 2.35 ( 2.12-2.49 ) , 7.83 ( 6. 54-8.90 ) and 8.76 ( 8.22-9.73 ) in mild, moderate and severe AD respectively, and the expression was higher in moderate and severe AD than in normal controls (Z= -6.237, -4.520,P ＜0.05). MIF serum concentrations were 8.98(7.90-10.51) μg/L, 36.50 (29.78-43.23) μg/L and 45.70(41.27-48. 84) μg/L in mild, moderate and severe AD respectively, and the differences were significant in moderate and severe AD compared to normal controls ( Z = - 6.238,- 4.521, P < 0.05 ). The lacrimal fluid MIF oncentrations were 1.10 ( 0.83-1.35 ) μg/L, 12.66 ( 9.76-15.87) μg/L and 24. 65 ( 19.29-30.94) μg/L in mild, moderate and severe AD respectively. Similarly,they increased significantly in moderate and severe AD compared to normal controls (Z = -4.062,- 3.372, P ＜ 0.05 ). In moderate and severe AD, MIF mRNA levels in PBMCs and MIF concentrations in sera and lacrimal fluid samples were all positively correlated with the severity of AD ( r = 0.395, 0.404,0.515, P < 0.05 ). Conclusions The expression of MIF in PBMCs, sera and lacrimal fluid samples is higher in different course of AD. MIF can serve as a useful laboratory parameter for evaluation of AD activity and severity.
