A pyelonephritis model of mouse is made by c. albicans infection. The determination of im-mune functions in model show that, both proliferation response of T cell to ConA and IL-2 activ-iting of spleenocytes of model animal to inductionwith ConA increased at 30 days after injected.The proliferation response of B cell to stimulation with LPS inhanced from 15 through 30 days,primary Ab response of model animal to SRBC stimulation inhanced between 15-30 days afterimmunization. DTH response to stimulation with c. albicans protein Ag raised since 15 days andup to peak at 30 days. Agglutination titer of serum raised up 15 days, and remained at higherlevel untill 30 days.

Objective Analyzing NNT epidemiological characteristics and the influeutial factors in Guangdong province from 2001 to 2005 in order to formulate the strategies for elimination NNT.Methods To make descriptive study on the data collected from NNT surveillance system. Results 2832 cases were concentrated in the Pearl River Delta and the west of Guangdong.About 72.04% NNT cases occurred in the migrant children.Through analyzing the data of the year of 2004 and 2005,73.81% of migrant NNT cases occurred in the Pearl River Delta.The cases happened in the Pearl River Delta accounted for 90.18% of whole cases.Most of local cases occurred in the west of Guangdong,which accounted for 39.04% of local cases.The cases occurred all around the year.A seasonal peak of NNT was found from June to August.Most of the onset of disease were during 2~10 days after birth.There were a higher ratio of reported male cases to the female.The ratio was 2.08∶1.Most of the NNT cases were happened to the infants who delivered at home and most of the midmives who were responsible for delivery lacked of training.99.75% mothers did not kown or administe the tetanus toxoid vaccine. Conclusion The elimination of neonatal tetanus is a difficult task in Guangdong province.Publicity to the mass should be strenghtened.The cooperation between sectors should be conducted for NNT eliminodion.

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 prepare recombinant human monoclonal antibody Fab fragments specific to the surface antigen of Entamoeba histolytica. Methods Total RNA was isolated from lymphocytes which were separated from an asymptomatic E. histolytica cyst carrier. The genes of IgG light chain and Fd region of heavy chain were amplified by a reverse transcriptase PCR and ligated with a plasmid vector. After the genes were introduced into Escherichia coli, the clones expressing Fab fragments specific to the surface antigen of E. histolytica were screened and the product was purified. Results Thirty thousand clones were screened and one of them was proved positive to the surface antigen of E. histolytica. Conclusion This study demonstrated that the bacterial system can be used to produce recombinant human monoclonal antibody Fab fragments specific to the surface antigen of E. histolytica and they may be applicable for the future diagnosis and treatment of the infection.

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.
