Objective To evaluate the significance of HCV-RNA testing of blood donors by using reverse transcriptase polymerase chain reaction (RT-PCR) analysis, and investigate HCV “window period” in blood donors.Methods Test blood donors for HCV-RNA by RT-PCR, and some positive cases were followed up. Results Among 28098 routine test negative blood donors, 77 (0.27%) were HCV-RNA positive. Eleven of the 77 HCV-RNA positive donors were followed up and 9 of them were later found to have increased ALT and/or positive anti-HCV. The interval between positive HCV-RNA test and abnormal serological tests was at least 4 weeks.Conclusion RT-PCR can identify HCV infected donors at an early stage. This test should become a routine test for blood donors to further ensure blood safety.

Objective:To investigate the significance of regulatory T cells in peripheral blood of chronic renal insufficientce.Methods:The peripheral blood samples were collected from 40 patients with chronic renal insufficient.The ratios ot CD4+T cell in lymphocyte and CD4+CD127-Treg and CD4+CD25+CD127-Treg in CD4+T were detected by flow cytometry.Results:The number of CD4+T in lymphocyte of chronic renal insufficient was higher than in healthy control group and there wasn’t significantly difference of the CD4+CD25+CD127-Treg ratios in CD4+T between chronic renal insufficience and healthy central.The ratio of CD4+T cells in lymphocytes of chronic renal insufficience was lower than in healthy control group except compensatory stage.There was no correlation between CD4+T cell ratios in lymphocytes,CD4+CD127-Treg or CD4+CD25+CD127-Treg ratios in CD4+T cells and the values of BUN,Cr among the hypertension patients.Conclusion:The number of CD4+T cells increases,and CD4+CD127-Treg decreases in the patients with chronic renal insufficience and their immune functions are shown in disoroler .

Objective To investigate the pathogens of acute respiratory infection of children.Methods A total of 159 children with acute respiratory infection who were hospitalized in our department from August 2005 to January 2006 were involved in this study.The serum IgM antibody of 18 pathogens were detected by indirect immunofluorescence test.The 18 pathogens included respiratory syncytial virus(RSV),adenovirus(ADV),influenza A(H1N1,H3N2)and B viruses,parainfluenza viruses(PIV) type 1,2,3 and 4,coxsackie virus B1(CBV1),coxsackie virus A7(CAV7),echovirus(ECHO7),haemophilus influenzae(HI),klebsiella pneumoniae(KP),bordetella pertussis(BP),bordetella parapertussis(BPP) and legionella pneumophila serotype 1 and 12.Results The evidence of specific IgM was obtained in 103 of 159 patients(64.78%).Influenza A was found in 66 cases(64.08%),influenza B in 49 cases(47.57%),enterovirus in 26 cases(25.24%),RSV in 18 cases(17.48%),PIV in 11 cases(10.68%),and co-infection in 66 cases(64.08%),1/ 3 of them were co-infected with influenza A and B.Conclusions Viruses are the most common agents of acute respiratory infection.Influenza virus is predominant among them.

Objective To compare the serum peptidome spectrum between nephrotic syndrome patients and normal controls, and to search for their variations. Methods The serum peptide profiling was determined by ClinProt magnetic bead enrichment and matrix assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) in 17 mesangial proliferative glomerulonephritis (MsPGN) patients, 12 minimal change nephrotic syndrome (MCNS) patients, 10 membranous nephropathy (MN) patients, 10 focal segmental glomerulosclerosis (FSGS) patients, and 10 healthy volunteers. Results 5 differentially expressed polypeptides were screened out between MsPGN and normal controls (15.28±7.61, P<0.01). 7 differentially expressed polypeptides were screened out between MCNS and normal controls (2.16±1.59, P<0.01). 6 differential expressed polypeptides were screened out between MN and normal controls (35.48±13.71, P<0.01). 5 differential expressed polypeptides were screened out between FSGS and normal controls (18.06±8.07, P<0.05). The statistical significance was set at P<0.05. A Genetic Algorithm was used to set up the classification model between patients and normal controls. The model separated MsPGN, MCNS, MN and FSGS group from normal controls with a cross validation of 96.18%, 100%, 98.53% and 94.12%, respectively. The recognition capabilities were 100%. Conclusions The study established the serum peptidome spectrum for nephrotic syndrome by proteomic technology, and provided a new viewpoint to better understand the pathogenesis of nephrotic syndrome.

OBJECTIVETo investigate the clinical effect of lateral superior genicular composite tissue flap for tissue defect.
METHODSThe axis line of flap is the lateral thigh vertical midline. The cutaneous branch is inserted 4 cm near the femoral lateral epicondylus. The anterior border is the elongation line along patellar lateral border. The posterior margin is the hinder margin of femoral biceps. The lower border is the horizontal line along the upper line of patella. The composite flaps were used in 18 cases with soft tissue defects in extremities, 11 cases with clacaneus tenden defects and 16 cases with bony nonunion. Results From Mar. 2002 to Sept. 2013, 45 cases were treated with the composite tissue flaps. The flaps size ranged from 6 cm x 3 cm to 17cm x 9 cm. All the flaps survived completely. Blood supply crisis happened in 2 cases, which was released by reanastomosis. The patients were followed up for 1 - 2. 5 years with satisfactory aesthetic and functional results. All the bone defect and nonunion were healed. Good healing was also achieved in donor sites. 8 months after operation, knee joint function is evaluated as good by hospital special surgery knee score (HSS).
CONCLUSIONLateral superior genicular compostie tissue flap can be used to reconstruct soft tissue defect, bone defect and tenden calcaneus defect in one stage.

OBJECTIVETo study the effects of combined use of total alkaloids (TA) of Uncaria rhynchophylla (UR) and Coryadlis ambailis migo (CAM) on cerebral ischemia/reperfusion injury in rats.
METHODSRat model of middle cerebral artery ischemia/reperfusion was established, the changes of neurological state was scored before and after treatment with the two kinds of TA, single or combined, and the changes of cerebral infarcted volume, cerebral water content, activities of NOS and SOD and content of MDA in rats' brain were estimated as well.
RESULTSAfter being treated with the combination of both TA, the average neurological score, cerebral infracted volume, cerebral water content, activity of NOS and content of MDA in the model rats significantly decreased, and the activity of SOD was significantly increased (all P < 0.05). The effect of combined use of the two TA was higher than that of use TA of UR or CAM alone (P <0.05). Moreover, the central nervous system inhibitory effect induced by combined TA was significantly weaker than that of UR.
CONCLUSIONCombined use of TA of UR and CAM may facilitate the protection against cerebral ischemia/reperfusion damage, the action mechanism might be relevant to reducing the lipid peroxidation injury of brain cells through inhibiting the NOS activity and increasing the SOD activity.
