Objective To measure the levels of human interleukin (IL)-32 in the serum and induced sputum of patients with chronic obstructive pulmonary disease (COPD) and investigate the possible roles of IL-32 in COPD.Methods Sixty patients with acute exacerbation of COPD ( AECOPD),60 patients with stable COPD,and 30 healthy subjects were recruited.The concentrations of IL-8,tumor necrosis factor alpha (TNF-α),and IL-32 in serum and induced sputum were measured by enzyme-linked immunosorbent assay (ELISA).The correlations among IL-32,IL-8,TNF-α,and lung functions were investigated. The data were analyzed using a statistical software package (SPSS 13.0).Variables were compared with one-way ANOVA,and correlations among variables were analyzed using Pearson's correlation coefficient or Spearman's correlation coefficient.Results The serum IL-32 level was significantly higher in AECOPD patients [(175 ± 88) ng/L] than in healthy subjects [ (59 ± 21 ) ng/L] and in stable COPD patients [ (89 ± 34) ng/L] (P ＜ 0.05) ; the serum IL-32 level was also significantly higher in stable COPD patients than in healthy subjects (P ＜ 0.05).The sputum IL-32 level was significantly higher in AECOPD patients [ ( 163 ± 117) ng/L] than in healthy subjects [ ( 75 ± 38 ) ng/L] and stable COPD patients [ ( 108 ± 63 )ng/L] (P ＜0.05); the sputum IL-32 level was also significantly higher in stable COPD patients than in healthy subjects ( P ＜ 0.05 ).The sputum IL-32 level in AECOPD patients was positively correlated with the sputum IL-8 and TNF-α levels (r =0.49 and 0.53,respectively) (P ＜0.01 ).The sputum IL-32 level in AECOPD patients was negatively correlated with FEV1 predicted values,FEV1/FVC,and PaO2 (r =-0.44to -0.33) (P ＜ 0.01 ).The serum IL-32 level in AECOPD patients was positively correlated with the serum IL-8 and TNF-o levels (r =0.45 and 0.61,respectively) (P ＜ 0.01 ).The serum IL-32 level in AECOPD patients was negatively correlated with FEV1 predicted values,FEV1/FVC,and PaO2 (r =-0.46to - 0.29) ( P ＜ 0.01 ).Conclusions IL-32 may be involved in the pathogenesis of airway inflammation in COPD.IL-32 may be a useful marker of acute exacerbation of COPD.

AIM: To study the chemical components from the bioactive extract of Chuanminshen violaceum Sheh et Shan in Sichuan province. METHODS: The isolation and purification of this extract were conducted by means of silica gels column chromatography.The structures of the compounds were elucidated based on their physical,chemical features and spectrum data. RESULTS: 8 compounds were isolated from the extract.They were elucidated as hexadecanoic Acid(A),2,6-dimethoxybenzoic acid(B),succinic acid (C),combination of sigmasterol and sitosterol(1(∶)1)(D),chrysophanol(E),8-hydroxy-5-methoxypsoralen(F),4-hydroxy-3-methoxybenzoic acid(G) and stigmasteryl 3-O-?-D-glucopyranoside(H). CONCLUSION: Compounds B,C,E,G were isolated from Chuanminshen violaceum for the first time.

The binding function of EGF1 domain peptide with tissue factor (TF) and its ability of triggering coagulation were explored. The TF expression model in vitro was established by lipopolysaccharide induction. The affinity of EGFP-EGF1 and TF expressing cells was analyzed by fluorescence microscopy and flow cytometry (FCM). The affinity of EGFP-EGF1 and rat soluble TF was quantitated by surface plasmon resonance (SPR). The ability of EGFP-EGF1 in triggering coagulation was tested by prothrombin time assay. The FCM results showed recombinant factor VII (rFVII) could definitely depress the integration of EGFP-EGF1 with recombinant TF (rTF) (68.65%+/-3.86% vs 57.98%+/-4.71%, P<0.01). The SPR results indicated the association constant ka of EGFP-EGF1 proteins was higher than rFVII (8.29+/-1.39 vs 3.75+/-0.32, P<0.01). However, the EGFP-EGF1 protein lost the activity of triggering coagulation as compared with blood plasma of normal SD rats (56.8+/-3.2 s vs 17.8+/-3.4 s, P<0.01). It was concluded that the rat EGF1 peptide could specifically bind to TF without the ability of triggering coagulation. EGF1 peptide may be a good target head for delivering drugs to TF in anticoagulation therapy.

ObjectiveTo explore the effect of musicotherapy on agitation behaviors in patients with aged dementia (AD).Methods22 AD patients were treated with different musicotherapies, and examined with Mini-Mental State Examination (MMSE), Cohen-Mansfield Agitation Inventory (CMAI) and self made sociality psychological inventory before and after treatment.ResultsAfter musicotherapy, the incidence rate of agitation behaviors of AD patients decreased significantly ( P<0.001). The incidence rates of agitation behaviors among patients with low, middle and high MMSE scores were significantly different ( P<0.001). After musicotherapy, both depressions of patients' cognitive function and scores of agitation behaviors were significant different compared with that before treatment (P<0.01). Effectual rates of musicotherapy on sociality psychological emotion, communication, language and intercourse of this group patients were 86.36%, 90.91%, 72.73% and 77.27%, respectively.ConclusionMusicotherapy can effectively alleviate the symptoms of agitation behaviors in AD patients.

Objective To evaluate the levels of oxidative stress in patients undergoing long-term and repetitive exposure to hyperbaric oxygen (HBO) treatment. Methods 16 healthy volunteers and 58 patients with sub-acute sudden hearing loss (SHL) exposed to HBO were included in the study. Oxidative stress indices (malondialdehyde, MDA, advanced oxidation protein products, AOPP; superoxide dismutase, SOD) were measured in peripheral blood samples collected at the 5th,10th, 20th and 30th HBO treatments sessions (PO2 0.18 MPa, 1 session per day and 5 sessions per week) and under normal ambient pressure respectively. Results After 5th,10th, 20th and 30th sessions of HBOT, no relevant differences in these three indices were detected compared to pre-HBO exposure, between healthy volunteers (P > 0.05). Conclusions The long-term repetitive HBO treatment for 0.18 MPa of PO2 and 30 sessions could not affect in particular the response of the oxidative stress in healthy persons and patients with sub-acute SHL. The influence on three indices of patients with abnormal situation of oxidative stress undergoing lower pressure of HBO (0.18 MPa) is under investigation.

Objective To investigate the association between cutaneous adverse drug reactions (CADRs) caused by antiepileptic drugs and HLA-B*1502 allele. Methods In 31 epileptic patients presented to the Epilepsy Clinic of the Second Affiliated Hospital of Guangzhou Medical College between January 2007 and May 2008, 13 had CADR to carbanazepine (CBZ) including 6 with Stevens-Johnson syndrome (SJS) and 7 with mild maculopapular exanthona (MPE);15 were CBZ-tolerant, and 3 had lamotrigine (LTG)-indueed MPE. All the patients underwent examinations using polymerase chain reaction with sequence specific palmers to analyze HLA -B*1502 allele frequencies, with 30 healthy subjects without a history of using CBZ or LTG as the control. Results HLA-B*IS02 allele frequency was 100% (6/6) in patients with CBZ-SJS, 57% (4/7) in patients with CBZ-induced MPE, and 33% (1/3) in patients with LTG-induced MPE. The frequency was 7% (1/15) in CBZ-tolerant patients and 10% (3/30) in the control subjects. Compared with the CBZ-tolerant patients and the control subjects, the patients with CBZ-induced SJS and MPE had significantly increased HLA -B*1502 allele frequency (P<0.05). Conclusions HLA-B*1502 allele is associated with CADRs to CBZ in epileptic patients.

OBJECTIVETo investigate the epidemiology and antibiotic resistance of isolates from hospitalized patients with hematological disease from 2005 to 2011.

METHODSA total of 1453 bacterial strains were isolated from patients with hematological disease from January 2005 to December 2011. Antimicrobial susceptibility testing was performed by micro-dilution method.

RESULTS(1) The majority of the bacterial strains were respiratory passage examples (57.5%). The portage of blood examples in our division (13.60%) was higher than of whole hospital (6.26%), with lower positive rate of bacterial culture (52.37%) than of whole hospital (60.24%). Chemotherapy-induced agranulocytosis was the main reason for hospital infection. 578 (39.8%) bacterial strains were gram positive, and 875 (60.2%) gram negative bacillus. Staphylococcus epidermidis strains and glucose nonfermenters had a tendency of ascensus. (2) Methicillin resistant staphylococcus aureus (MRSA) accounted for 72.8% antibiotic resistance. Detection rates of ESBLs in Escherichia coli and Klebsiella pneumoniae were 18.9% and 10.4%, respectively. (3) No obvious changes of antimicrobial resistances of Staphylococcus and Enterococcus were observed during these years. The Enterobacteriaceae strains showed lowest resistance rates to Carbapenems, next to Cefoperazone/sulbactam and Piperacillin/tazobactam. But the resistance rates of Escherichia coli to Cefepime and Ceftazidime were gradually increasing during the past years. Pseudomonas aeruginosa and Acinetobacter baumannii of glucose nonfermenters showed lowest resistance rates to Cefoperazone/sulbactam, but the resistance rate of Pseudomonas aeruginosa to Carbapenems increased.

CONCLUSIONSEscherichia coli was the highest in quantity of gram negative bacillus and glucose nonfermenters had a tendency of ascensus. The resistance rates of Escherichia coli to Cefepime and Ceftazidime, Pseudomonas aeruginosa to Carbapenems were gradually increasing in the past years.
