Objective To investigate the renal function changes of the children with breast milk jaundice(BMJ) and effect of early interference treatment on renal function. Methods Serum bilirubin and urine - minim protein (?2-MG,?1-MG, Alb and IgG) of the 50 patients with BMJ were measured when they were in hospital within 12 hours and the last day separately , at the same time, 20 healthy newborns had been chosen to serve as control group. Results Compared with control group, the urine minim protein of treatment group increased with the rise of serum bilirubin. When serum bilirubin was 205.2 - 256.5 ?mol/L, urine ?2- MG had mild increasing (P

OBJECTIVETo investigate the clinical significance of the deletion of the long arm of chromosome 13 [del (13 q) ] and translocation of immunoglobulin heavy chain gene [t (14 q) I in multiple myeloma (MM) patients.

METHODSMyeloma cells were isolated from hone marrow by direct immunomagnetic cell sorting and interphase fluorescence in situ hybridization (FISH) was performed in 24 MM patients to detect del (l3q) and t (l4q).

RESULTSThe positive rates of del (l3q) and t (l4q) were 45.83% and 37.50% respectively. Five patients (20.83%) had both two abnormalities and 15 patients (62.50%) had at least one abnormality. Univariate analysis showed that the positive rates of del (l3q) were 35.71% and 66.67% in responders and non-responders (P = 0.214) and the positive rates of t (l4q) were 21.43% and 66. 67% in responders and non-responders (P = 0.077). Multivariate analysis showed that del (13q) (OR = 5.761, 95% CI 0.500-66.391, P = 0.160), t (14q) (OR = 6.576, 95% CI 0.580-74.614, P = 0.129), and corrected serum calcium level (OR = 8.080, 95% CI 0.738-88.427, P = 0.087) were relatively independent negative factors for response to therapy, with the corrected serum calcium level being the strongest reversely-correlated factor.

CONCLUSIONSInterphase FISH is a sensitive method to investigate the cytogenetics of MM. Del (13q), t (14q), and corrected serum calcium level can be used to predict treatment response and prognosis.

The study was aimed to investigate the genetic background and proliferation characteristics of multiple myeloma (MM). Myeloma cells were isolated from bone marrow of 19 MM patients by direct immunomagnetic cell sorting and the DNA content and cell cycle analysis were carried out by flow cytometry. The results showed that in 4 patients the myeloma cells were found to be hyperdiploid and in 15 patients those were found to be diploid respectively by DNA content analysis; the proportion of plasm cells from normal controls in S + G(2)/M phase was (1.15 +/- 0.60)%, and that of myeloma cells from MM patients was (10.06 +/- 12.60)% which was significantly higher than that in the former (p = 0.001). The incidence of hyperdiploid in newly diagnosed patients was 11.76%, and that of treated patients was 100.00% which was significantly higher than that in the former (p = 0.035); the proportion of myeloma cells from newly diagnosed patients in S + G(2)/M phase was (7.12 +/- 4.98)%, and that of treated patients was (35.10 +/- 32.56)% which was also significantly higher than that in the former (p = 0.001). It is concluded that the variety of myeloma cells in DNA content and cell cycle suggests the complicated genetic background and abnormal proliferation of MM, which relate with the course of disease to some extent.

Hemophagocytic lymphohistiocytosis (HLH) is a lifethreatening disorder due to hyperinflammation resulting in infiltration of different organs with extensive hemophagocytosis. Severe coagulopathy was one of the main reasons for death in HLH. Over secretion of plasminogen activator by activated macrophages leads to hyperfibrinolysis. We reported a 36-year-old woman who was diagnosed as HLH probably secondary to lymphoma. Massive bleeding from gut and retroperitoneal area were not able to be controlled by conventional hemostatic treatments. This patient received one dose recombinant activated factor VII (rFVIIa) 3.6 mg (70 μg/kg). Hemostatic effect was achieved in 0.5 hour and lasted 24 hours. Prothrombin time (PT) and activated partial thromboplastin time (APTT) were quickly corrected to normal ranges. Fibrinogen level elevated from 0.5 g/L before using rFVIIa to 1.8 g/L 20 hours after. Although dexamethasone and etopside were administrated to treat HLH, this patient died from septic shock after persistent neutropenia. This suggests that rFVIIa may be effective in the management of intractable hemorrhage in patients with HLH.

An expression plasmid carrying anthrax protective antigen (PA) gene was constructed, which has an OmpA signal sequence attached to the 5' end of PA gene. The plasmid was transformed into E. coli and induced to express recombinant PA (rPA) . The recombinant protein, about 10% of the total bacterial protein in volume, was secreted to the periplasmic space of the cell. After a purification procedure including ion-exchange, hydrophobic interaction chromatography, and gel filtration, about 15 mg of 95 % pure rPA was obtained from 1-liter culture. The bioactivity of rPA was proved by in vitro cytotoxicity assay. The polyclonal antiserum from rabbits immunized with rPA could inhibit the action of anthrax lethal toxin in vitro, which suggests that antibodies against rPA can provide high passive protection against anthrax. The results reported here may be helpful to develop a safe and efficacious recombinant PA vaccine against anthrax.

OBJECTIVETo assess the value of rheumatoid factors IgM-RF, IgA-RF, IgG-RF, interleukin-1 receptor type I (IL-1RI) and cyclin-dependent kinase 2 (CDK2) in the diagnosis of rheumatoid arthritis (RA).

METHODSIgM-RF, IgA-RF, IgG-RF, IL-1RI and CDK2 were detected in 47 patients with active RA, 47 with inactive RA, 20 with active systemic lupus erythematosus (SLE), 20 with inactive SLE, 20 with acute upper respiratory tract infection (AURTI), and 20 healthy controls using enzyme-linked immunosorbent assay (IgM-RF, IgA-RF, IgG-RF, IL-1RI) and time-resolved fluoroimmunoassay (CDK2).

RESULTSPatients with active and inactive RA showed significant differences in peripheral serum CDK2 and IgA-RF levels (P<0.05). Between active and inactive RA patients, RA patients and SLE patients, RA patients and AURTI patients, and RA patients and the control subjects, the area under curve (AUC) of the receiver operating characteristic curve (ROC) was 0.561, 0.814, 0.799, and 0.888 for IgM-RF, 0.596, 0.678, 0.729, and 0.850 for IgA-RF, 0.614, 0.718, 0.692, and 0.791 for IgG-RF, 0.646, 0.691, 0.762, and 0.835 for IL-1RI, 0.803, 0.753, 0.741, and 0.840 for CDK2, respectively.

CONCLUSIONSIgM-RF may have high value in the diagnosis and differential diagnosis of RA, and CDK2 can be useful for differential diagnosis between active and inactive RA.
