The incidence of systemic fungal infections have increased dramatically, moreover, drug resistance including either primary (intrinsic) or secondary (acquired) resistance, becomes one of the main reasons accounting for the failure of treating invasive fungal infections in the past decades. Nowadays, clinically available antifungal drugs are limited and their combination in antifungal therapy was not effective. It is expected to be a new strategy to synergistically sensitize antifungal drugs against drug-resistant fungi by using new small molecules. Based on the study in our research group and the reported work of others, we reviewed the research of the natural products which have synergistic effect with the antifungal agents against drug-resistant fungi. This review focused on the resource, structure, pharmacological activity, and action mechanism of the compounds, as well as somewhat in common, and would provide theoretical base for seeking new drug against drug-resistance fungi.

Objective To explore the relationship between wild rodent plague and human in wild rodent plague foci of the northwestern area in Yunnan to probe the possible transmission mechanism of wild rodent plague to human. Methods Data of component ratio of rodents and fleas was collected in different areas from 1985 - 1995. Activities and habits of residents regarding the way they keep cats and dogs and parasitic fleas and free fleas indoor were investigated, the dog serum was collected for detecting F1 antibody. Results Eothenomys miletus were main rodents in farmland and shrub, accounting for 48.00% (4753/9902) and 54.50% (4282/7857), Apodemus chevrieri were main rodents in garden, being 50.47% (1332/2639). The component ratio of Neopsylla specialis specialis was 13.31%(229/1720), 12.31%(1678/13 739) and 10.87%(957/8802) respectively in garden, farmland and shrub, higher than in indoor. The component ratio of Frantcpsylla spodix was 39.88% (686/1720), the highest in garden. Thirty-two per cent (32/100) of residents kept cats,in which 63% (20/32) with cat fleas, 68% (68/100) of villages kept dogs, in which 76%(52/68) with fleas. Eighteen parasitic fleas were caught from 43 dogs with a flea index of 0.119 and a rate for fleas of 11.63%, 7 pulex were collected from 17 indoor. Forty-three blood serum samples were obtained from dogs, among which 3 were positive blood serum. Conclusions Residents touch affected animals or media in different situations. The possibility of transmission for wild rodent plague to human exists in loci in a chain of wild rodent plague → fleas or predation → homebred animal plague (cats or dogs) →touching or respiratory → human.

To evaluate the efficacy and safety of pegylated-interferon (Peg-IFN) treatment as monotherapy or in combination with nucleoside analogues (NAs) for treating chronic hepatis B (CHB) infection.Searches of PubMed, OVID, EMBASE, and the Chinese Medical (WanFang, CNKI, and VIP) databases were conducted to identify all relevant randomized controlled trials published since January 1990. Twelve studies comparing Peg-IFN monotherapy to NA combination therapy (lamivudine (LAM), n =8); adefovir (ADV), n = 4) met the inclusion criteria (treatment duration, range: 48-52 weeks; follow-up, range: 24 weeks to three years). Meta-analysis was performed with RevMan 5.0 using the fixed-effects and random-effects models. Patients who had received combination therapy had a higher biochemical response rate at the end of treatment than those who had received monotherapy (51.1% vs. 38.9%, odds ratio (OR) = 1.63, 95% confidence interval (CI): 1.33-2.01, P less than 0.01). Subgroup analysis of Peg-IFN combination therapies with LAM or ADV indicated that neither NA type significantly enhanced the increased efficacy of combination therapy compared to monotherapy. The combination therapy subgroups also had higher virologic response rates at the end of treatment than the monotherapy subgroups (LAM: 65.9% vs. 34.9%, OR = 3.57, 95% CI: 1.83-6.95, P less than 0.01; ADV: 74.6% vs. 46.2%, OR = 3.66, 95% CI: 2.13-6.30, P less than 0.01). Moreover, the combination therapy group had a higher sustained biochemical response rate at the end of follow-up than the monotherapy group (47.6% vs. 42.1%, OR = 1.28, 95% CI: 1.05-1.55, P less than 0.05). The LAM combination therapy subgroup had a significantly higher biochemical response rate than the monotherapy subgroup, but there was no significant difference between the LAM and ADV combination therapy subgroups. At the end of follow-up, the ADV combination therapy subgroup had a significantly lower rate of hepatitis B e antigen (HBeAg) than the monotherapy subgroup, but there was no significant difference between the ADV and LAM combination therapy subgroups for HbeAg reduction. The combination therapy group and monotherapy group showed no statistically significant differences in HBsAg reduction or occurrence of severe adverse events. Peg-IFN/NA combination therapy produces a higher biochemical response rate in CHB patients than PEG-IFN monotherapy. Moreover, Peg-IFN/ADV combination therapy produces a greater reduction in HBeAg than Peg-IFN monotherapy.

Objective To investigate the effect of lemon peel extracts(LPE) on the activity of lactate dehydrogenase and sucrase of Streptococcus mutans (Sm). Methods After serial dilution with trypticase soy broth (TSB) medium containing 2% glucose, LPE was used as the experimental group, and TSB without LPE as the control group. Sm was added to each group,which was then cultured for 6,18,24 and 48 hours in the anaerobic tank. The activity of lactate dehydrogenase (LDH) was measured with the method of oxidation of reduction coenzyme I and the pH value of the culture solution was also detected. The activity of the sucrose was determined with the method of coloration of 3,5-dinitrosalicylic acid. Results The activity of LDH, sucraae and the changes of solution pH were decreased with the increase of the concentration of LPE (P < 0. 01 ). The activity of LDH were declined from (0. 8025 ± 0. 0913 ) × 103 U/L to (0. 2099 ±0. 0283) × 103 U/L; the activity of sucrase were declined from ( -0. 0107 ±0. 0003) × 103 U/L to ( -0.0078 ±0.0002) × 103 U/L; the△pH were declined from(2.8067 ±0.0404) to (2.5033 ±0. 0416) (24 h results). The differences were significant between experimental groups and the control group (P < 0. 01 ), and there were also significant differences among experimental groups with different LPE concentration( P <0. 01 ). The inhibitory effect of acid generation and lactate dehydrogenas' activity of Sm were positively correlated ( P < 0. 01 ). Conclusions LPE can inhibit the activity of lactate dehydrogenase,sucrase and the acid production capacity of the Sm in a dose dependent manner. The inhibitory effects in logarithmic phase is stronger than that in other phases of growth cycle.
