Objective To investigate the effects of elasticity resistance (Ers) in respiratory system on oxygenation in patients with acute lung injury (ALI) after recruitment maneuvers (RM). Method Meta-analysis of data about the effects of recruitment maneuvers on oxygenation in ALI patients with different elasticity resistances in respiratory system carried out with pooling of study-oriented data stored in Pubmed, Embase, Web of Science databases from January 1999 to June 2010. Results A total of 281 articles were taken, and 20 of them included a sample size of 395 ALI patients. In patients treated with RM in different degrees of respiratory system elasticity resistance ( ≥33.3 cmH2O/L and <33.3 cmH2O/L), the effect of RM was better in patients with the high respiratory system elasticity resistance than that with the low one [(51.97 + 8.89) mmHg vs. (35.13 ± 10.33 ) mmHg], P < 0. 01 ), but the high respiratory system elasticity resistance was potentially to lower blood pressure [(4. 33 ± 1.32 ) mmHg vs. (0.22 ± 1.03 ) mmHg],P < 0.01 ). Conclusions This study suggests RM could improve oxygenation of ALI patients with high respiratory system elasticity resistance, and caution must be made to avoid hypotension during RM.

OBJECTIVESince the advent in 2004 of highly active antiretroviral therapy (HAART) in Liaoning, a dramatic improvement had been seen in the number of patients attaining undetectable viral loads (92/104), but the extent of mutation diversity on human immunodeficiency virus 1 (HIV-1) and the prevalence of drug resistance had remained elusive. This study aimed to analyze both HIV-1 mutation profiles and prevalence related to antiretroviral resistance following therapeutic failure.
METHODSA total of 104 blood samples circling Liaoning from HAART-treated between 2004 and 2008 were studied. Patients' CD(4)(+) T-cell count and viral load were determined. HIV-1 pol (PR and part of RT) gene fragments were amplified from patients' plasma by reverse transcriptase polymerase chain reaction (RT-PCR) and nest-PCR, subsequently sequenced and analyzed.
RESULTSCD(4)(+) T cell numbers and viral replication capacity were assessed. 88.4% (92/104) of the patients were successful after initial non-suppressive NRTI & NNRTI-based HAART regimens. Subjects on non-nucleoside reverse transcriptase inhibitor (NNRTI) regimens developed more (6/104) drug-resistance mutations than those on nucleoside reverse transcriptase inhibitor (NRTI) regimens did (5/104). No protease-inhibitor (PI) drug resistance mutations developed. The whole rate of drug resistance mutations was about 6.73%. Subjects developing NNRTI-resistance (NNRTI-R) seemed more likely to develop drug-resistant viremia than with NRTI-based HAART.
CONCLUSIONThis finding might have implications in which that the prevalence of drug-resistance mutations was low but remained risk of transmission in HIV-infected therapeutic failure. Meanwhile, data from the present study showed that there was a high frequency of primary mutations, which offered resistance to nrti and nnrti. Monitoring patients with treatment failure seems an important tool in helping the physicians to improve their treatment schedule and to carry out epidemiological surveillance programs.

Objective A resistin binding peptide (RBP) was selected by phage display in our previous work. Studies had shown that RBP could antagonize the role of resistin on the lipid metabolism and endocrine function of adipose tissue, but whether RBP affects the insulin secretion of pancreatic cells is still unknown. The aim of this study is to assess the effect of RBP on basal insulin secretion in RINm5F insulinoma cells. Methods The cell viability was measured by 3-[4,5-dimethyhhiazol-2-yl]-2,5-diphenyltetra-zolium bromide (MTT) cytotoxicity assay. The supernatants were assayed for insulin content by enzyme linked immunosorbent assay (ELISA). Reverse transcriptase-PCR assay and Western blotting were used to determine the expression of glucose transporter 2 (GLUT2) involved in insulin secretion. Cytosolic Ca2+, the trigger of insulin exocytosis, was analyzed with the fluorescent probe FURA-3/AM. Results RBP did no effect on the cell viability with a concentration of 10-8-10-12mol/L of 2 hours intervention. But it stimulated basal insulin secretion of RINm5F cells, accompanied by up-regulated increased expression of GLUT2 and elevated concentration of cytosolic Ca2+. Conclusion RBP could stimulate basal insulin secretion without affecting the cell viability.

OBJECTIVETo study the related proteins of apoptosis initiation induced by homoharringtonine (HHT) in HL-60 cells.
METHODSAfter establishment of an apoptosis initiation model induced by HHT in HL-60 cells, proteins of untreated and HHT treated HL-60 cells were extracted, and the two-dimensional polyacrylamide gel electrophoresis (2-DE) maps of the extracted proteins were established by using the immobilized pH gradient (IPG) two-dimensional electrophoresis respectively. The alteration protein spots were identified with assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and database searching.
RESULTSProteomics analysis showed that proteins including MHC class I antigen, calbindin D-28K, chloride channel protein 6, oncoprotein 18, zinc finger protein Helios and apoptosis inhibitor like protein 2 were involved in apoptosis initiation induced by HHT.
CONCLUSIONThe present study might conduce to the researches of HL-60 cells carcinogenesis and pave the way to exploit drug precursor related to HHT and initiation of apoptosis in HL-60 cells.

OBJECTIVETo study the effects of DNA vaccine transdermal delivery with microneedle array.
METHODSThe pcDNA3.1-HPV16E7 recombinant vector acting as gene vaccine was established. The infiltration quantity of pcDNA3.1-HPV16E7 getting across the microchannels generated by microneedle arrays in vitro was observed. 30 BALB/c mice were divided into 3 groups (experimental group, in vain plasmid group, negative control). Each group had 10 mice. Then immunized BALB/c mice with a dose of 200 microg with microneedle array every two weeks. The control groups did the same as that as the study groups. Two weeks after the third immunization, the serum and lymphocytes were separated to detect the functions of humoral immunity with indirect immunofluorescence test, while, the functions of cellular immunity with lymphocyte transformation test was also detected.
RESULTSThe DNA vaccine could easily get across the microchannels generated by microneedle arrays in vitro. Moreover, the course was permanent and the whole infiltration quantity was comparatively high, reaching 0.73819 mg/cm2 at the 30th hour. And among immunized BALB/c mouse, DNA vaccine transdermal delivery with microneedle array could induce specific antibodies. Lymphocyte transformation test showed that there was significant difference for the lymphocyte transformation rate between experiment (the average of lymphocyte transformation rate was 47.25%) and control group (the average of lymphocyte transformation rate was 30.00%) (chi2 = 12.903, P < 0.001). Also, the difference was found between in vain plasmid group (the average of lymphocyte transformation rate was 43.00%) and negative control(chi2 = 7.292, P = 0.007). While, no difference was observed in the experimental group and in vain plasmid group (chi2 = 0.817, P = 0.366).
CONCLUSIONThe DNA vaccine combined administering with microneedle array might get across the microchannels generated by microneedle arrays in vitro and induce humoral and cellular immune response in vivo.

OBJECTIVETo evaluate the relationship between periodontitis and the traditional risk factors of coronary heart disease (CHD), as well as the role in the mechanisms responsible for high-sensitivity C-reactive protein (hsCRP) in the relationship of peridontitis and CHD.
METHODSA periodontal examination was conducted on a total of 356 subjects, and community periodontal index of treatment needs (CPITN) was obtained from each subject. Periodontal status was categorized into TN < or =2, TN=3, TN=4 three groups according to the CPITN indexes. Fasting venous blood samples were collected from all the three group subjects, the serum hsCRP concentration and serological changes used in diagnosing CHD routinely were determined, and software of SPSS 16.0 were used to analyzed the relationship of periodontal, hsCRP concentration and routinely CHD serological indexes.
RESULTSIn the groups of TN < or =2, TN=3 and TN=4, the hsCRP level was (1.10 +/- 1.16), (1.86 +/- 2.34), (2.25 +/- 2.75) mg x L(-1), respectively. Compared with Group TN < or =2, the concentration of hsCRP in Group TN=3 and TN=4 were higher (OR = 1.24, OR = 1.31, respectively). Compared with group hsCRP < 3.0 mg x L(-1), more calculus and deep periodontal pockets were found in the Group hsCRP > or = 3.0 mg x L(-1) (P < 0.05).
CONCLUSIONThe serum hsCRP level is correlated with the severity of periodontal disease.
