OBJECTIVETo explore clinical effects of internal fixation in treating displaced clavicle fracture combined with coracoid process.

METHODSFrom January 2005 to July 2012, 9 patients with displaced clavicle fracture combined with coracoid process were treated by internal fixation. Among them, there were 6 males and 3 females with an average age of 40.1 (ranged from 20 to 57) years old. According to Eyres classification: 3 cases were type II B, 1 case was type II A, 3 cases were type III B, and 2 cases were type V A. All patients had history of injury, and diagnosed as coracoid fracture X-ray and CT before operation. Herscovici criteria was used to evaluate function of shoulders joint after operation.

RESULTSSeven of 9 patients were followed up from 6 to 18 (averaged 11) months. The incisions were healed at stage I, coracoid process obtained bony healing, and reduction of acromioclavicular joint well. According to Herscovici criteria, 6 patients got excellent results and 1 in good.

CONCLUSIONInternal fixation for the treatment of displaced clavicle fracture combined with coracoid process could restore physiological anatomical position of coracoid process, and benefit for recovery of limb function.

Objective To study the effects of rehabilitation(RT)on cardiac function in cerebral infarct (CIF)patients with cardiac insufficiency(CIS).Methods Fifty-nine CIF patients with CIS were randomly divid- ed into a treatment group(T group,n=29)and a control group(n=30),and all patients were treated with routine pharmacotherapy for 2 months.In addition,RT was administrated in the T group at the same time.The grading of the New York Heart Association(NYHA)and the changes in cardiac function associated index were observed in both groups before and after treatment.Results Compared with the control group,NYHA grades,left ventricle ejection fraction(LVEF),the levels of brain natriuretic peptide(BNP)in the blood plasma,and the 6min walking range of the T group patients were all significantly improved after treatment(P＜0.05).Conclusion RT can improve car- diac function in CIF patients with CIS.

This article aimed to study the antigenicity of nucleocapsid proteins (NPs) in six pathogenic phleboviruses and to provide theoretical evidence for the development of serological diagnostic reagents. NPs of six pathogenic phleboviruses were expressed and purified using a prokaryotic expression system and rabbits were immunized with individual recombinant NPs. Cross-reactions among NPs and rabbit sera were determined by both indirect ELISA and Western blotting analyses, and the sera titer was determined by indirect ELISA. Furthermore, sera from SFTS patients were also detected by each recombinant NP as a coating antigen using indirect ELISA. The cross-reactions and the sera titer were subsequently determined. Both the concentration and purity of recombinant NPs of six pathogenic phleboviruses met the standards for immunization and detection. The results of indirect ELISA and Western blotting showed that each anti-phlebovirus NP rabbit immune serum had potential serological cross-reactivity with the other five virus NP antigens. Furthermore, the sera from SFTS patients also had cross-reactivity with the other five NP antigens to a certain extent. Our preliminary study evaluated the antigenicity and immune reactivity of six pathogenic phleboviruses NPs and laid the foundation for the development of diagnostic reagents.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

AIMTo investigate the complexation of prostaglandin E1 (PGE1) with hydroxylpropyl-beta-cyclodextrin (HP-beta-CD) in aqueous solutions, inclusion molar ratio of the host and guest molecules and change of thermodynamic parameters during the complexation process.

METHODSThe measurements of the complexation mechanism, inclusion molar ratio of the host and guest molecules and change of thermodynamic parameters were carried out by the following methods separately: phase solubility method, UV absorption spectroscopy, circular dichroism spectroscopy, equimolar series method and thermodynamic method, respectively.

RESULTSThat all the phase solubility diagrams showed a typical AL-type in various pH buffered solutions, suggested the formation of a soluble complex of 1:1 molar ratio. Both UV absorption spectroscopy and circular dichroism spectroscopy confirmed that the significant interaction between the host and guest molecules was probably due to the inclusion of chromophore moiety of PGE1 molecule into the hydrophobic cavity of HP-beta-CD molecule. The change in the thermodynamic parameters suggested that the complexation could proceed spontaneously along with the release of heat and the decrease of entropy.

CONCLUSIONAn 1:1 molar ratio inclusion complex of PGE1 with HP-beta-CD could be formed spontaneously and, hence, the solubility of PGE1 in aqueous solution increased. Appropriate temperature and suitable media pH probably favor the progress of complexation procedure.

This study aims to investigate whether the nucleoprotein (NP) of severe fever with thrombocytopenia syndrome virus (SFTSV) can impact the cellular immunity of host cells. Gene segments that encode the NP and non-structural protein (NSs) of SFTSV were inserted into eukaryotic expression vector VR1012. Host proteins that interact with NP and affect immunity were identified with co-immunoprecipitation (IP), SDS-PAGE, mass spectrometry (MS), and Western blot. Co-localization of NP and the identified host proteins was confirmed by confocal microscopy. A 60kD SSA/Ro, a protein related to immunity, interacted with NP, as found by IP and MS. Confocal microscopy showed that NP and SSA/Ro were co-localized in cytoplasm. These results indicated that SFTSV NP may specifically bind to 60kD SSA/Ro and cause a series of immune responses and clinical symptoms.

To establish a MacELISA method for the detection of IgM antibodies against Chikungunya virus (CHIKV), we prepared virus like particle (VLP) antigens of CHIKV using the whole structural protein C-E3-E2-6K-E1 encoding gene with a baculovirus expression system in Sf9 insect cells. The VLPs were purified and used to immunize Kunming mice. Then, polyclonal antibodies were purified from the samples of ascites with a protein G HiTrap SP column and labeled with horseradish peroxidase. A MacELISA method for the detection of IgM antibodies against CHIKV was assembled with goat anti-human IgM antibody, VLP antigens and an enzyme-labeled polyclonal antibody. The results were evaluated with a serum panel containing serum samples from laboratory-confirmed CHIK, HFRS patients, healthy donors, and commercially available CHIKV IgM as a quality control. It was shown that the MacELISA had a specificity of 99% (99/100), the coefficients of variation (CoV) within a plate were <10%, and the CoV of different ELISA plates in terms of the plate variation coefficient was <15%. A comparative analysis was performed to compare the current method against a commercial CHIKV IgM antibody detection kit for IIFA-IgM. The detection limit of MacELISA was significantly lower than that of the IIFA-IgM commercial kit (P< 0.0001). Here, we demonstrate that the VLP-based MacELISA is a promising tool for the early diagnosis and epidemiological investigation of CHIKV infection, with a high level of sensitivity and specificity for the detection of IgM antibodies against CHIKV.

OBJECTIVETo access the sustained immune effect in influenza A H1N1 vaccine vaccinated-blood donors as well as the level of anti-H1N1 IgG in unvaccinated-blood donors in order to provide reference for preventing and treating influenza A H1N1.

METHODSAnti-H1N1 IgG was detected in 1166 vaccinated-blood donors as well as 1265 unvaccinated-blood donors by ELISA method in Dongguan from January 2010 to June 2010.

RESULTSThe mean positive rate and high-titer rate of anti-H1N1 IgG were 78.82% and 46.57% respectively, both of which were sustained at relatively high level after reaching their peak at vaccination time of 71-90 d. The mean positive rate of anti-H1N1 IgG in unvaccinated-blood donors was 26.01%. No difference was found in the positive rate of anti-H1N1 IgG among different gender or age groups (P > 0.05).

CONCLUSIONThe influenza A H1N1 vaccine, with good sustained immune effect, plays an important role in preventing and treating influenza A H1N1. The positive rate of anti-H1N1 IgG in influenza A HIN1 vaccine unvaccinated-blood donors is low. Vaccination should be strengthened.
