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

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.

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.

Human adenovirus serotype 5 (HAd5) infect dendritic cells with low efficiency which restricts the use of HAd5 as an antigen carrying vector in such cells. Aiming to find a novel strategy to detour the traditional method for more convenient clinical use, peripheral blood mononuclear cells isolated from Chinese rhesus macaques were chosen as the target cells for HAd5. In vitro infection protocol was optimized which indicated centrifugation at 1000g could ease the entry of adenovirus. By this protocol, CD14 positive monocytes were infected at high efficiencies (> 80%), and about 10% of natural killer cells were infected; while T and B lymphocytes were rarely infected. Interestingly and importantly, it was the first time to report that in our in vitro study monocytes were more susceptible to HAd5-EGFP in macaques with higher preexisting vector specific neutralizing antibody titers. This phenomenon indicates an expansion of application of adenovirus based vectors for vaccine development and clinical use, especially for the population with preexisting neutralizing antibodies.

To establish the method of immunophenotyping testing for patients with multiple myeloma (MM), to analyze the characteristics of antigen expression on myeloma cells, and to purify primary myeloma cells, CD45/side scatter (SSC) gating tri-color immunofluorescence (IF) flow cytometry (FCM) was used to test immunophenotype of 18 patients with MM, 20 patients with acute leukemia (AL) and 7 normal controls. Purified primary myeloma cells were obtained by means of anti-CD138 monoclonal antibody and immunomagnetic microbeads. The results showed that myeloma cells displayed a CD45 negative/low positive expression, and SSC was located between nucleated red blood cells and neutrophils. Both CD138 and CD38 were positive while most antigens of T cell, B cell and myeloid cell were negative. Positive rate of CD56 was 83.3% and HLA-DR was 44.4% positive. Compared with MM patients, CD138 was negative and CD38 was 100% positive in AL patients. CD56 was 25% positive. In normal controls, neither CD138 nor CD56 was positive. The positive rate of primary myeloma cells after purification was 73%-95% with a mean of 86%. It is concluded that CD45/SSC gating procedure is a stable and reliable method to detect immunophenotype of MM. CD138 is a correspondingly special antigen for myeloma cells. Highly enriched primary myeloma cells can be obtained by anti-CD138 antibody and immunomagnetic microbeads.

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.

OBJECTIVETo find the reasons why patients always have temporomandibular disorders (TMD) after condylar fracture by analyzing the stress distribution change of the condylar surface whose subcondylar fracture ware fixed by miniplate during the whole healing process.
METHODSAnalyzing the stress distribution change of the condylar surface whose subcondylar fracture were fixed by miniplate during the whole healing process by three-dimension finite element method (3D FEM).
RESULTSDuring the whole healing process of the fracture, the miniplate osteosynthesis was helpful to the biomechanics environment rehabilitation of the condylar local, but it still had difference with normal after fixing 12 weeks long.
CONCLUSIONThe difference of stress distribution of condylar surface that fractured and fixed by miniplate with normal may be part of the reason of TMD after the subcondylar fracture miniplate osteosynthesis.
