Objective To investigate the function of myeloid dendritic cells (mDCs) from severe aplastic anemia ( SAA ) patients in stimulating allogeneic T lymphocytes proliferation in vitro and then explore the immunopathogenesis of SAA. Methods Twenty-five SAA patients ( 15 untreated and 10 recovered after immunosuppressive therapy) and 12 normal controls were enrolled in this study. Their mature mDCs were induced from their bone marrow monocytes with recombined human interleukin-4 ( rhIL-4) , recombined human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) and recombined human tumor necrosis factor (rhTNF) in vitro. Then mDCs were co-cultured with allogeneic lymphocytes (mixture lymphocyte reaction, MLR) at a ratio of 1: 100 or 1: 50. The growth rate of lymphocyte was measured with methyl thiazolyl tetrazolium ( MTT) colorimetry.The concentrations of interleukin( IL) -12 and inlerferon -y (IFNγ) in MLR supernatant were measured with EL1SA. The correlation between the growth rate and the concentration of IL-12 or IFNγ was analyzed. Results When mDCs and lymphocytes were co-cultured at the ratio of 1: 100, the growth rates of lymphocytes stimulated with mDCs from untreated, recovered SAA patients and controls were (219. 8 ±94. 0)% , (159. 1 ±66. 0)% and (160. 1 ±91. 9)% respectively. The concentrations of IL-12 in MLR supernatant were (8. 2 ± 3. 6) ng/L, (6. 5 ± 2. 8) ng/L and (6. 1 ± 2. 6) ng/L and the concentrations of IFNγ were (21. 8 ± 8. 7) ng/L, (25. 5 ± 9. 1) ng/L and (22. 6 ± 7. 8) ng/L respectively. All of them had no statistical differences among the three groups ( P > 0. 05 ). When mDCs and lymphocytes were co-cultured at the ratio of 1: 50, the growth rate of lymphocytes stimulated with mDCs from untreated patients was (322. 1 ± 171. 1)% , which was higher than that of recovered patients [ (180. 9 ±79. 1)% and controls (192. 3 ±91. 9)% ]. The concentrations of IL-12 in MLR supernatant in the three groups were (12.6 ±4.4) ng/L, (9.4 ±3.3) ng/L and (8.5 ±3.7) ng/L, and the concentrations of IFNγ were (32. 3 + 9. 2 ) ng/L, ( 27. 4 ± 6. 5) ng/L and (24. 4 ± 7. 4 ) ng/L Both of the values in untreated cases were higher than those of the recovered cases or controls (P < 0. 05 ) , but there were no statistical difference between the recovered and control groups ( P >0. 05 ). The concentration of IL-12 in MLR supernatant correlated positively with the growth rate of lymphocyte (r=0. 529,P <0. 01) and so did the concentration of IFNγ (r = 0. 381, P < 0. 05). Conclusion The function of mDCs to stimulate T lymphocytes proliferation in SAA was enhanced; it might play an important role in the immunopathogenesis of SAA.

OBJECTIVETo investigate the relationship between paraoxonase (PON) polymorphisms and serum homocysteine thiolactone (HTL) and coronary heart diseases.

METHODIn this prospective study, serum complex of HTL levels using ELISA, and the lever of serum Hcy using high pressure liquid chromatography (HPLC), determined the PON1/T(-107)C and PON2/C311S genotypes using PCR-restriction fragment length polymorphisms 203 were measured in patients with angiographic documented coronary heart disease (CAD) and 117 controls.

RESULTSSerum levels of Hcy and the complex of HTL in CAD patients were significantly higher than that in controls (P < 0.05). No significant difference was found in frequencies of PON1/T(-107)C genotypes and alleles (P > 0.05) between CAD patient and controls. The PON2/C311S (SS) genotype was lower in CAD patients than that in controls (P < 0.05), while the frequency of allele was similar between the two groups (P > 0.05). The T allele of PON1/T(-107)C and S alleles of PON2/C311S polymorphism were associated with lower plasma Hcy and HTL complex [Hcy (11.83 +/- 4.76) micromol/L vs (15.32 +/- 10.32) micromol/L, P < 0.05; HTL complex (24.36 +/- 9.30) U/ml vs (32.05 +/- 10.44) U/ml, P < 0.05]. The genetype PON2 and allele C were higher in CAD patients with type 2 diabetes than that in CAD patients without type 2 diabetes and controls (P < 0.005).

CONCLUSIONSThe elevation of serum Hcy and the complex of HTL were associated with increased risk of coronary heart disease. The allele PON1/(-107)T and PON2/311S might be protective for the development of atherosclerosis.

OBJECTIVETo investigate serum level and gene polymorphisms of matrix metalloproteinase 9 (MMP-9), and platelet glycoprotein VI (GPVI) in patients with acute coronary syndrome (ACS).

METHODSIn a prospective study of 179 patients with documented ACS and 164 controls, we measured baseline serum MMP-9 levels using ELISA and determined the MMP-9/C-1562T and MMP-9/G5564A genotypes using PCR-restriction fragment length polymorphism. Fib serum level was measured by Clauss assay. We also analyzed the Fib/Bbeta-148C/T and GPVI/T13254C polymorphisms.

RESULTSSerum levels of MMP-9 and Fib in ACS patients were significantly higher than in controls (P < 0.001), and serum level of Fib in the acute myocardial infarction group was higher than in patients with unstable angina (P < 0.05). No significant difference between ACS patients and controls was found in frequencies of MMP-9/C-1562T, MMP-9/G5564A, Fib/Bbeta-148C/T, and GPVI/T13254C genotypes and alleles (P > 0.05). The T allele of the Fib/Bbeta-148T polymorphism was associated with increased plasma Fib level (P < 0.05). There was a strong positive correlation between serum level of MMP-9 and Fib (r = 0.289, P < 0.01).

CONCLUSIONSerum levels of MMP-9 and Fib were independent risk factors of ACS. There was an obvious relationship between the Bbeta-148C/T mutation and high Fib level. No significant difference between controls and ACS patients was found in the frequencies of MMP-9 C-1562T and G5564A, Fib Bbeta-148C/T and GPVI T13254C genotypes and alleles (P > 0.05).

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

OBJECTIVETo discuss the Chinese version of reflux symptom index (RSI) scale's reliability, validity and clinical value.

METHODSUsing the Chinese version of RSI scale on the ENT outpatients. There are one hundred and seven patients, included thirty-five patients with common throat (non-suspected) and seventy-two patients with clinically suspected throat reflux. 107 patients are to complete the two scales before and after one week. Thirteen patients with common throat(non-suspected) diseases and forty-one with suspected throat reflux also received RSI testing. Among the thirty-four confirmed acid reflux disease patients, thirty patients received pharmaceutical treatments and self-performed post-RSI testing after three months.

RESULTSThe RSI Scale internal reliability consistency included the test-retest reliability (0.750 - 0.971), discriminant validity and construct validity. RSI total targeting percentage of 66.7%, targeting percentage is 80.8%, discriminant validity using 2 independent samples Wilcoxon test, RSI total score compared to Z = -3.266, P = 0.001. The before and after treatment self-control chi-square test (P < 0.05), difference was statistically significant.

CONCLUSIONSRSI Simplified Chinese version has good reliability and validity, and can be used for laryngopharyngeal reflux disease (LPRD) diagnostic screening along with the efficacy for the treatment of patients with appropriate LPRD aids.

OBJECTIVETo investigate the pharmacokinetics and pharmacodynamics of poly (lactide-co-glycolide) microspheres containing ropivacaine and dexamethasone for sciatic nerve block in mice.

METHODSA total of 165 female mice were randomly assigned into 3 groups, namely dexamethasone-loaded ropivacaine microsphere group (group A, n=55), ropivacaine microsphere group (group B, n=55) and PLGA microsphere group (group C, n=55). The mice received surgical implantation of the corresponding preparations near the sciatic nerve at the dose of 400 mg/kg. Hot plate test was used to evaluate the anesthetic effect of these microspheres at different time points after the implantation, and high-performance liquid chromatography (HPLC) was employed to determine plasma ropivacaine concentration.

RESULTSPharmacodynamic study showed that the duration of sciatic nerve sensory block was significantly longer in group A than in group B (P<0.05). The analysis of pharmacokinetics variables demonstrated that T(1/2) in group A was prolonged as compared with that of group B. No anesthetic effect was observed in group C.

CONCLUSIONDexamethasone-loaded ropivacaine microspheres can significantly prolong the analgesic effect of ropivacaine in mice.
