ABSTRACT

Objective:To evaluate the clinical efficacy of Qingkailing injection in the treatment of children with sepsis and heat syndrome, and investigate its anti-inflammatory, anticoagulant and protective effects. Method:Eighty patients were randomly divided into control group and observation group with forty cases in each group according to the number table. Both groups received comprehensive treatment measures such as fluid resuscitation, anti-infection, anti-inflammatory, anticoagulation, vasoactive drugs, and protection of vital organ functions. While patients in observation group additionally took Qingkailing injection, 5-10 mL each time, intravenous drip after dilution, 1 time/day. Treatment course was five days in both groups. Before and after treatment, the scores of quick sequential organ failure assessment (qSOFA), pediatric critical illness score (PCIS) and acute physiology and chronic health evalution Ⅱ (APACHEⅡ) were graded; procalcitonin (PCT), serum amyloid A protein (SAA) before and after treatment, heparin-binding protein (HBP), tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), IL-10, N-terminal brain sodium Peptide precursor (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT) level, cardiac troponin I (cTnI), creatine kinase isoenzyme (CK-MB), <italic>D</italic>-dimer (<italic>D-</italic>D ), fibrinogen (FIB) and antithrombin Ⅲ (AT-Ⅲ) levels were detected. Result:The APACHEⅡ and qSOFA scores in the observation group were lower than those in the control group (<italic>P</italic><0.05), while the PCIS score was higher than that in the control group (<italic>P</italic><0.05). The levels of PCT, SAA,HBP,TNF-<italic>α</italic>, hs-CRP and IL-6 in the observation group were lower than those in the control group (<italic>P</italic><0.01), while the IL-10 level was higher than that in the control group (<italic>P</italic><0.01). The levels of NT-proBNP, hs-cTnT, cTnI, CK-MB, <italic>D</italic>-D and FIB in the observation group were lower than those in the control group (<italic>P</italic><0.01), while the AT-Ⅲ activity was higher than that in the control group (<italic>P</italic><0.01). Conclusion:Qingkailing injection as the adjuvant therapy in children with sepsis and fever syndrome, can play the role of anti-inflammatory, anticoagulant, reducing infection and myocardial damage, thereby reducing the severity of the disease and improving the prognosis.

ABSTRACT

OBJECTIVE@#To investigate the correlation of single nucleotide polymorphisms (SNP) in arachidonate 5-lipoxygenase gene (ALOX5) rs2029253, rs2228064 and rs2228065 sites, 5-lipoxygenase activating protein gene (ALOX5AP) rs10507391, rs4769874 sites with the risk for genesis of adult myeloid leukemia.@*METHODS@#By the approval from the hospital ethics committee and the informed consent of participants. 150 patients with myeloid leukemia (ML) as ML group and 134 healthy people as the control group were selected. The genomic DNA was extracted from the samples. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) combined with directly sequencing, PCR-amplified products were applied to test the polymorphism of 5 sites in ALOX5 and ALOX5AP gene.@*RESULTS@#A allele frequencies of ALOX5 gene rs2029253 site in the ML group and the control group were 43.0% and 34.3%, respectively. And the G allele frequencies in the ML group and the control group were 57.0% and 65.7%, respectively. The genotype distributions of AA, AG and GG in ALOX5 gene rs2029253 site in the ML group were 32.2%, 21.5% and 46.3% respectively. That in the control group were 15.7%, 37.3% and 47.0% respectively. The genotype AA and A allele frequency of ALOX5 gene rs2029253 site were linked with the increased risk of myeloid leukemia (OR=2.26, 95% CI: 1.43-4.56, P<0.05; OR=1.44, 95% CI: 1.02-2.03, P<0.05). And the genotype AG and allele G reduced the susceptibility to myeloid leukemia (OR=0.46, 95% CI: 0.27-0.78, P<0.01; OR=0.69, 95% CI: 0.50-0.98, P<0.05), however, the polymorphisms of ALOX5 gene rs2228064 and rs2228065 site not correlated with the risk of myeloid leukemia (P>0.05). The A allele frequency of ALOX5AP gene rs10507391 site in the ML group and the control group were 30.7% and 36.2% respectirely. The genotype distribution rates of AA, AT and TT in ALOX5AP gene rs10507391 site in the ML group was 1.3%, 58.7% and 40.0% respectively, that in the control group were 9.7%, 53.0% and 37.3% respectively. The genotype AA of ALOX5AP gene rs10507391 site correlated with the decreased risk of myeloid leukemia (OR=0.13, 95% CI: 0.03-0.57, P<0.05), but the polymorphism of ALOX5AP gene rs4769874 site not correlated with the risk of myeloid leukemia (P>0.05).@*CONCLUSION@#The genotype AA, AG and allele A, G of ALOX5 rs2029253, as well as ALOX5AP rs10507391 may be correlate with the susceptibility to myeloid leukemia.

ABSTRACT

Objective@#To analyze the correlations of seminal plasma (sp) anti-Müllerian hormone (spAMH) and inhibin B (spINHB) and serum INHB (serINHB) with semen parameters in oligoasthenospermia patients and explore their value in predicting the outcome of routine in vitro fertilization (IVF).@*METHODS@#We obtained the levels of spAMH, spINHB and serINHB as well as semen parameters from 88 infertile males undergoing IVF due to oligoasthenospermia or female uterine tubal factors from August 2016 to February 2017. Using the ROC curve and Pearson's correlation analysis, we examined the effects of the obtained parameters on the fertilization rate and assessed the correlation of the levels of spAMH, spINHB and serINHB with the semen parameters of the patients.@*RESULTS@#Concerning the predictive value for the outcome of IVF, Pearson's correlation analysis showed that the area under the ROC curve (AUC) of spAMH was 0.807 (sensitivity = 84.6%, specificity = 76%, cut-off point = 3.529, P <0.001) and that of spINHB was 0.768 (sensitivity = 84.6%, specificity = 88.7%, cut-off point = 31.117, P = 0.002). The serINHB level was found positively correlated with sperm concentration (r = 0.346, P = 0.001), total sperm count (r = 0.378, P <0.001), sperm motility (r = 0.521, P <0.001), and the percentage of progressively motile sperm (r = 0.343, P = 0.001).@*CONCLUSIONS@#The levels of spAMH and spINHB can be used as laboratory indexes to predict the fertilization rate of routine IVF and are correlated with semen parameters in oligoasthenospermia patients, while that of serINHB has a positive correlation with the semen parameters of the patients.

ABSTRACT

Objective To investigate the AIDS-related high risk behaviors of men who havesex with men (MSM) who ever exchanged money for the same sex. Methods Target sampling forcross-sectional study and valid anonymous questionnaires were adopted to compare the differences ofAIDS-related high risk behaviors between MSM with the experience of exchanging money for thesame sex and those without that experience. 1959 rstadied samples were recruited in nine cities. SPSS13.0 was used and t, x 2 and Mann-Whitney tests were taken for statistical analysis. ResultsCompared to corresponding ones without "buying" the same sex experience, MSM who ever engagedin "buying" sex had the characteristics of being prone to in marriage and living in larger cities witholder age and higher income (P<0.01). They also had a significant larger number in the followingevents: total sexual panners, anal sex and oral sex episodes with same sex, number of sexualpartners, anal sex and oral sex in the previous six months, with the figure of median 50.0, 20.0,20.0, 5.0,4.0,5.0 respectively. 31.5% had ever participated in 'group sex', 48.0% had sex with malepartners away from his own region in the previous year, 70.5% had sexual intercourse withstrangers at MSM avenues in the last six months. The OR (95% CI) values were 2.288( 1.702-3.077), 3.231 (2.462-4.241 ), 2.840 (2.140-3.770). All the above mentioned figures werehigher than those without the experience, with significant differences. They had a significant lower rate of 45.7% of condom use while having sex with female partners (P<0.05). Conclusion MSM with the experience of exchanging money for the same sex would have more AIDS-related high risk behaviors, AIDS preventative measures should be taken to target different subgroups.

ABSTRACT

Objective To explore the risks on sexual behaviors related to AIDS among men who having sex with men (MSM) in floating population and to develop relevant interventions. Methods Study objectives were recruited through target sampling and anonymous questionnaires were adopted. Male sexual behaviors were compared between floating population and permanent registered residents.Results Among those MSM, the average numbers of same-gender partners, oral sex, anal sex and sex with females during the past 6 months among floating population were 9.61, 8.61, 7.52 and 1.17 respectively. Numbers of partners on oral sex and anal sex during the past month were 2.89 and 3.69 respectively. Both figures were higher than those of the permanent registered residents (P<0.05 or P< 0.01). The rates of condom use among floating population when having anal sex with men or with non-marital female partners were 37.15% and 23.28% respectively. The figures were all higher than those of permanent registered residents' (P<0.05 or P<0.01). Among floating population, the percentages of men who had sex with male sex workers or who had sex with men acquainted through inter-net or with stable female sex partners were 17.89%, 12.56%, and 31.86% respectively. The rates of men who had group sex among gay men, who bled when having sex with men or who had sex with men from other areas during the past year were 22.13%, 31.38% and 32.36% respectively. The figures were all higher than those of permanent registered residents' (P<0.05 or P<0.01). Conclusion Sex-related high risk behaviors were more ubiquitous among floating population than those of permanent registered residents because they were more likely to transmit HIV to people from/to other areas. More attention should be paid to the floating population with MSM in particular, when health interventions are carried out.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the inhibitory effect on HBV replication of antisense locked nucleic acid (LNA) targeting to both S and C genes in HBV transgenic mice.</p><p><b>METHODS</b>Thirty HBV transgenic mice were randomly divided into five groups (n = 6): glucose control group were treated with 5% glucose solution, liposome control group were treated with liposome alone, S group were treated with LNA targeting to S gene, C group were treated with LNA targeting to C gene, and dual-target group were treated with LNA targeting to both S and C genes. Antisense LNA was injected into mice via the tail vein. Serum HBsAg was quantified by TRFIA. Serum HBV DNA was quantified by real-time PCR. The expression of HBV C-mRNA in the liver was detected by RT-PCR. The expression of HBsAg and HBcAg in the liver was detected by immunohistochemistry. Serum ALB, ALT, BUN and CR were measured using an automatic biochemical analyzer. The effects of antisense LNA on mouse organs were investigated by HE staining.</p><p><b>RESULTS</b>5 days after LNA injection, serum HBsAg levels in the dual-target group were reduced by 72.8%, and serum HBV DNA levels were decreased by 52.9%. These values were significantly higher than those in the control groups (all P < 0.05). No significant differences were noted in serum ALB, ALT, BUN and CR between the experiment groups and the control groups (all P > 0.05). The expression levels of HBsAg and HBcAg in the liver of dual-target group were significantly lower than those in the control groups. No significant histopathological abnormality was found in liver and kidney tissues in all groups.</p><p><b>CONCLUSION</b>Antisense LNA targeting to both S and C genes can significantly inhibit HBV replication in transgenic mice.</p>

ABSTRACT

<p><b>BACKGROUND</b>The balance between vasodilation and vasoconstriction plays a major role in maintaining vascular homeostasis. However, the underlying mechanisms are unclear. More and more evidence suggested that there was an interaction in the regulation of vasorelaxation between nitric oxide (NO) and hydrogen sulfide (H(2)S). We explored the interaction between and effects of NO and H(2)S on the relaxation of pulmonary arteries in rats.</p><p><b>METHODS</b>Seven male Sprague-Dawley rats were anaesthetized with chloral hydrate and the pulmonary arteries of each rat separated for the study of vascular activities. The vasorelaxing activities of pulmonary artery rings in response to different doses of a NO donor, sodium nitroprusside (SNP), or a H(2)S donor, sodium hydrogen sulfide (NaHS), were measured in vitro. When pulmonary artery rings were treated with a cystathionine-gamma-lyase inhibitor, DL-propargylglycine, in the presence of SNP or a nitric oxide synthase inhibitor, N(omega)-nitro-L-arginine methyl ester, in the presence of NaHS, the changes in relaxing activities were analyzed.</p><p><b>RESULTS</b>The relaxation of pulmonary artery rings was in a dose dependent manner in response to either SNP or NaHS. The relaxation rates of pulmonary artery rings increased from (30.90+/-4.62)% to (60.50+/-8.08)% when the concentration of SNP increased from 1 micromol/L to 3 micromol/L and from (26.13+/-4.12)% to (53.09+/-14.01)% when the concentration of NaHS increased from 25 micromol/L to 100 micromol/L. However, when appropriate inhibitor was added, the relaxation responses to SNP and NaHS decreased.</p><p><b>CONCLUSIONS</b>The results suggested that similarly to NO, H(2)S acted as a vasorelaxant either independently of, or synergistically with NO in the regulation of vasorelaxation. The interaction between NO and H(2)S played an important role in regulating relaxing activities of pulmonary arteries.</p>
