OBJECTIVETo analyze the incidence, clinical features and the predisposing factors of fungal septicemia, and investigate the risk factors for death due to fungal septicemia and the prognosis of the patients.
METHODSWe retrospectively analyzed the clinical data of 91 patients with fungal septicemia diagnosed in the last 17 years, including 60 patients with clinical cure or improvement, and 31 who die of the disease. Based on the results by univariate analysis, the data were analyzed using logistic multiple regression and Fisher's discriminant analysis.
RESULTSFungal septicemia had many predisposing factors with high mortality rate. Univariate analysis revealed significant differences between the cured/improved cases and the fatal cases for 12 variables, including advanced age, complication by bacterial infection, septic shock, multiple organ dysfunction syndrome (MODS), ICU patients, cortical hormone therapy, surgery, chemotherapy, use of immunopotentiating agents, length of hospital stay before antifungal therapy, time of anti-fungus therapy and types of invasive procedures. Logistic multiple regression analysis showed that the types of invasive procedures, MODS, surgery and prolonged hospital stay before antifungal therapy were the independent risk factors for fungal septicemia-related death. Fisher's linear discriminant equation was established for predicting the prognosis of the disease.
CONCLUSIONThe types of invasive procedure, MODS, surgery and prolonged hospital stay before antifungal therapy are the independent risk factors for fungal septicemia-related death, and the patients' prognosis can be predicted using Fisher's linear discriminant equation.

OBJECTIVETo investigate the risk factors of fungal rhinosinusitis.
METHODSThe preoperative clinical data of 57 patients with a diagnosis of fungal rhinosinusitis confirmed pathologically using Gomori methenamine silver staining were analyzed statistically against the data of 57 age- and gender-matched control patients with chronic rhinosinusitis.
RESULTSCompared with chronic rhinosinusitis, fungal rhinosinusitis was characterized by a significantly shorter mean disease course (37.31 months vs 130.84 months, t = 5.59, P = 0.000). The factors related to fungal rhinosinusitis included nasal mucus, purulent nasal discharge, unilateral/bilateral sinus lesion and calcified plaque in CT scan , with odds ratios of 0.17 (0.04-0.62), 0.35 (0.15-0.80), 41 (12.50-100.00) and 91 (24.01-344.95), respectively. Conditional logistic regression identified calcified plaque in CT scan as the high-risk factor of fungal rhinosinusitis.
CONCLUSIONThe presence of calcified plaque in CT scan indicates high risk of fungal rhinosinusitis and may serve as an important evidence for diagnosis of this disease.

OBJECTIVETo investigate the pharmacokinetics of nalmefene after intravenous administration at a single or multiple doses in Chinese healthy volunteers.
METHODSThis open, randomized clinical trial involved 12 healthy volunteers, who received a single-dose (2 mg) nalmefene injection. Before and at different time points after the injection, blood sample were obtained from the subjects. After the single intravenous dose trial, 8 healthy volunteers received intravenous nalmefene at 2 mg once daily for 6 consecutive days, and the plasma drug concentrations were determined on the morning of days 4, 5 and 6 using liquid chromatography/tandem mass spectrometry and the pharmacokinetic parameters were calculated using PKS program.
RESULTSThe main pharmacokinetic parameters of nalmefene (Cmax, Tmax, T1/2, AUC0-48, and AUC0-infinity) after the single intravenous dose were 7.34-/+1.56 microg/L, 0.08 h, 12.01-/+2.20 h, 30.29-/+9.84 microg.L(-1).h, and 32.23-/+9.94 microg.L(-1).h, respectively; the parameters after multiple doses were 8.04-/+1.09 microg/L, 0.08 h, 12.43-/+1.44 h, 33.64-/+9.15 microg.L(-1).h and 35.98-/+9.23 microg.L(-1).h, respectively. The steady-state pharmacokinetic parameters including the degree of fluctuation (DF), AUCss and Cav were 4.69-/+1.29, 19.64-/+6.20 microg.L(-1).h and 1.64-/+0.52 microg/L, respectively.
CONCLUSIONNalmefene showed similar pharmacokinetics in Chinese healthy volunteers with those in the foreign testees, and can be safely administered in healthy volunteers without producing unmanageable pain.

As part of our ongoing influenza surveillance program in South China, 19 field strains of H9N2 subtype avian influenza viruses (AIVs) were isolated from dead or diseased chicken flocks in Guangdong province, South China, between 2012 and 2013. Hemagglutinin (HA) genes of these strains were sequenced and analyzed and phylogenic analysis showed that 12 of the 19 isolates belonged to the lineage h9.4.2.5, while the other seven belonged to h9.4.2.6. Specifically, we found that all of the viruses isolated in 2013 belonged to lineage h9.4.2.5. The lineage h9.4.2.5 viruses contained a PSRSSRdownward arrowGLF motif at HA cleavage site, while the lineage h9.4.2.6 viruses contained a PARSSRdownward arrowGLF at the same position. Most of the isolates in lineage h9.4.2.5 lost one potential glycosylation site at residues 200-202, and had an additional one at residues 295-297 in HA1. Notably, 19 isolates had an amino acid exchange (Q226L) in the receptor binding site, which indicated that the viruses had potential affinity of binding to human like receptor. The present study shows the importance of continuing surveillance of new H9N2 strains to better prepare for the next epidemic or pandemic outbreak of H9N2 AIV infections in chicken flocks.

OBJECTIVETo investigate the correlated factors and clinical features of fungal rhinosinusitis.
METHODSThe clinical data of 110 patients with fungal rhinosinusitis treated by surgery and another group of 110 patients with chronic rhinosinusitis who were sampled randomly between January 1999 and June 2004 in our hospital were retrospectively compared. The correlated factors and the clinical features of fungal rhinosinusitis were investigated by using the multiple factor Logistic regression analysis and chi-square test. The pathological types of 110 fungal rhinosinusitis were classified by using Gomori methenamine silver staining which was special for fungi.
RESULTSThe logistic regression predictive equation for fungal rhinosinusitis was : y = -8.713 + 0.496x1 + 4.575x2 + 1. 190x3 + 4.119x4 + 1.199x5 + 2. 698x6, P = exp (y)/[1 + exp(y)], in which the concomitant variables were course of the disease (x1), haem-nasal discharge (x2), headache (x3), calcified plaque in CT scan (x4), age (x5) and unilateral/bilateral sinus lesion (x6), respectively. The P value meant the probability of suffering fungal rhinosinusitis. Compared with chronic rhinosinusitis, the clinical features of fungal rhinosinusitis were female, over 40-year-old, course of disease < 3 years, headache, haem-nasal discharge, unilateral sinus lesion and calcified plaque in CT scan. Among the 110 patients with fungal rhinosinusitis, 34 cases were chronic invasive and 76 were non-invasive.
CONCLUSIONSThe clinical features of fungal rhinosinusitis are significant for the diagnosis, and it can be predicted by using the suitable logistic predictable equation.

Objective To examine whether polymorphisms of histone deacetylase( HDACs) and environment factors can be implicated in type 2 diabetes mellitus ( T2DM) ,and to provide evidence for the prevention and treatment of T2DM. Methods In 2017,T2DM patients and controls were selected from 17 villages in Huadu District,Guangzhou. According the Diagnostic criteria for T2DM,the case group of T2DM was matched with control group from the population diagnosed as normal by gender,age no more than 5 years old,and from the same natural village. Conditional logistic regression model was used to analyze the effect of gene and environment and their interaction on T2DM. Results The average age of 499 cases group were ( 61.53±13.08) years old,and the average age of 499 controls group were ( 61.48±13.09) years old. There were no statistic difference between two groups. Furthermore,the two groups were gender-balanced too. In conditional logistic regression model,we found that glycerin trilau- rate ( TG) abnormalities ( OR= 2.410,95% CI: 1.755-3.310,P<0.001) and cholesterol total ( TC) ab- normalities ( OR= 1.436,95% CI: 1.046-1.972,P = 0.025) were risk factors for T2DM. The subjects carries rs72792338 TC+TT genotype ( OR= 0.526,95% CI: 0.349-0.793,P= 0.002) had lower the risk to develop T2DM. Conclusions Abnormal TG and TC are risk factors for T2DM. Rs72792338 TT and TC genotype carryings decrease the risk of T2DM.

OBJECTIVETo evaluate the efficacy and safety of Magnesium isoglycyrrhizinate in treatment of chronic liver diseases.
METHODSIt is a randomized, double-blind, multi-doses, active drug controlled, multi-center study. 480 proper patients were randomly divided into group A (180 patients), group B (180 patients) or group C (120 patients). Patients in group A received magnesium isoglycyrrhizinate 100 mg once daily. Patients in group B received magnesium isoglycyrrhizinate 150 mg once daily. Patients in group C received compound glycyrrhizin 120 mg once daily. The treatment course was 4 weeks. Patients were followed up 2 weeks after the treatment. Patients visited once every 2 weeks. Clinical symptoms, ALT, AST were evaluated in all the patients before treatment, at week 2, at week 4 and at 2 weeks later after treatment. The other liver function test was done before treatment and at week 4.
RESULTS412 patients completed the study according to the protocol,152 in group A, 160 in group B and 100 in group C. ALT and AST level were significantly decreased in all groups at week 2 and week 4 (P < 0.05). The degree of ALT decrease is greater in group B than in group C at week 2 (P < 0.01). The degree of ALT decrease was not significant different among three groups at week 4 (P > 0.05). The rates of ALT improvement at week 4 in group A, B, C were 92.59%, 91.76%, 88.29%, respectively (P > 0.05). The rates of symptoms improvement at week 4 in group A, B, C were 90.41%, 89.86%, 86.46% and 72.22%, 73.53%, 68.47%, respectively (P > 0.05). No relapse were found in all three groups after treatment. The rate of adverse event in three groups was similar (P > 0.05).
CONCLUSIONMagnesium isoglycyrrhizinate is an effective and safe treatment for chronic liver diseases.
