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.

OBJECTIVETo study the effect of aqueous extract of Taxus chinensis var. mairei (AETC) combined Erlotnib on the growth of A549 xenograft in nude mice and its mechanism.
METHODSThe xenograft model in nude mice was established by inoculating A549 cells subcutaneously. BALB/c nude mice bearing A549 xenograft were randomly divided into six groups, i.e., the low dose Erlotinib group (A) , the standard dose Erlotnib group (B) , the low dose Erlotinib combined AETC group (C), the standard dose Erlotnib combined AETC group (D), the AETC group (E), the control group (F), 12 in each group. Different medication was performed for 7 successive weeks after 24 h. One mL blood was withdrawn and tumor tissues taken. The tumor inhibition rate was calculated. The combined effect was analyzed by Jin's Formula [Q = Ea + b/(Ea + Eb-Ea x Eb) ]. mRNA and protein expression levels of epidermal growth factor receptor (EGFR), cyclooxygenase-2 (COX-2), and B cell lymphoma-2 (Bcl-2) in xenografts were detected using real-time RT-PCR and ELISA.
RESULTSCompared with Group F, the xenograft weight was obviously lowered in Group B-E (P < 0.05, P < 0.01). The q value was 0.92 in Group C and 0.96 in Group D, which was obtained by simple adding of the two drugs. Compared with Group F, EG- FR mRNA expression in Group D and E, COX-2 mRNA expression in Group A-E; Bcl-2 mRNA expression in Group B-D; COX-2 protein expression in Group B-E; Bcl-2 protein expression in Group C and D were obviously lowered with statistical difference (P < 0.05, P < 0.01).
CONCLUSIONSAETC combined low dose and standard dose Erlotinib had synergistic effect on tumor inhibition. Its mechanism might be associated with down-regulating mRNA and protein expression levels of COX-2 and Bcl-2.

Objective To evaluate the impact of epidural anesthesia with levobupivacaine combined with general anesthesia on colon surgery. Methods Sixty patients undergoing elective radical procedure for colon carcinoma were randomLy divided into four groups: saline group (group S), 0.125% levobupivacaine group (group L1), 0.25% levobupivacaine group (group L2), and 0.5% levobupivacaine group (group L3). Group S received normal saline of 10 mL epidurally and then infusion of 5 mL·h-1 until the procedure was finished; groups L1, L2, and L3 received levobupivacaine instead. Anesthetic induction was performed after epidural puncture. Mean blood pressure and heart rate were recorded at 8 time points including 5 min after entering into the operation room, 1 min after intubation, skin incision, abdominal exploration, 1 h after skin incision, completion of operation, extubation, and leaving PACU; meanwhile blood glucose and cortisol were detected, anesthesia time, time to PACU stay, bleeding, transfusion volume, adverse reaction, and doses of propofol, remifentanil, ephedrine, and fentanyl were noted. Results Time to PACU stay was longer in S group than in other 3 groups. Doses of remifentanil and fentanyl were larger in L1 group than in L2 group and L3 group. Ephedrine dose in L3 group was larger than in other 3 groups. Blood sugar in L1 group was higher than L2 group and L3 group. Cortisol in S group was higher than in other 3 group. Cortisol in L1 group was higher than in L3 group. The number of patients with hypotension was greater in L3 group than other 3 groups. Conclusions Continue epidural infusion of 0.25%levobupivacaine can reduce stress response and opioid uses, shorten PACU stay, whereas it does not increase use of ephedrine.

OBJECTIVE:To establish a method for the determination of dasatinib concentration in human plasma and study the bioequivalence of 2 kinds of tablets. METHODS:In a randomized two-way crossover study,24 healthy male volunteers were divid-ed into two groups,and were administered respectively with test and reference preparations 100 mg under fasting and fed condi-tions. The plasma concentration of dasatinib was determined by LC-MS/MS. Using imatinib mesylate as internal standard,the deter-mination was performed on Welchrom C18 column with mobile phase consisted of acetonitrile-0.1% formic acid(70∶30,V/V). Posi-tive ion scanning was conducted under MRM mode,ESI,and ion pair for quantitative analysis were m/z 488.5→401.2 (dasatinib) and m/z 494.6→394.2(internal standard). DAS 3.2.8 software was used for data processing and variance analysis was adopted to in-vestigate the bioequivalence of 2 kinds of tablets. RESULTS:The linear rang of dasatinib was 1-300 ng/ml. The pharmacokinetic pa-rameters of test and reference preparations under fasting conditions were as follows:cmax were (165.599 ± 67.592) and (164.533 ± 77.960)ng/ml;tmax were(1.145±0.504)and(1.080±0.467)h;t1/2 were(5.080±2.262)and(3.771±1.596)h;AUC0-36 h were (550.487 ± 256.494) and (585.986 ± 324.885) ng·h/ml. The pharmacokinetic parameters of test and reference preparations under fed conditions were as follows:cmax were(163.058±47.533)and(165.440±53.012)ng/ml;tmax were(1.630±1.066)and(1.576± 0.530)h;t1/2 were(4.720±2.677)and(4.311±2.610)h;AUC0-36 h were(568.036±192.521)and(601.100±216.855)ng·h/ml. Relative bioavailability of AUC0-36 h under fasting and fed conditions were(100.2±7.5)% and(99.2±3.8)%. Analysis of variance showed there were no significant difference in the pharmacokinetic parameters of between 2 preparations and cyde(P>0.05),there was statistical significance among subjects(P<0.05). CONCLUSIONS:LC-MS/MS method can determine the concentration of da-satinib in human plasma rapidly;and the two preparations are bioequivalent.
