Regan Syrup has the effect of clearing heat, releasing exterior, benefiting pharynx and relieving cough, and previous phase Ⅱ clinical trial showed that the efficacy of Regan Syrup high-dose and low-dose groups was better than that of the placebo group, and there was no statistically significant difference in the safety between the three groups. The present study was conducted to further investigate the efficacy and safety of the recommended dose(20 mL) of Regan Syrup in the treatment of common cold(wind-heat syndrome). Patients who met the inclusion and exclusion criteria were selected and divided into the test group(Regan Syrup+Shufeng Jiedu Capsules placebo), positive drug group(Regan Syrup placebo+Shufeng Jiedu Capsules) and placebo group(Regan Syrup placebo+Shufeng Jiedu Capsules placebo) at a 1∶1∶1 using a block randomization method. The course of treatment was 3 days. A total of 119 subjects were included from six study centers, 39 in the test group, 40 in the positive drug group and 40 in the placebo group. The onset time of antipyretic effect was shorter in the test group than in the placebo group(P≤0.01) and the positive drug group, but the difference between the test group and the positive drug group was not significant. The test group was superior to the positive drug group in terms of fever resolution(P<0.05), and had a shorter onset time of fever resolution than the placebo group, but without obvious difference between the two groups. Compared to the positive drug group, the test group had shortened disappearance time of all symptoms(P≤0.000 1). In addition, the test group was better than the positive drug group and the placebo group in relieving symptoms of sore throat and fever(P<0.05), and in terms of clinical efficacy, the recovery rate of common cold(wind-heat syndrome) was improved in the test group compared to that in the placebo group(P<0.05). On the fourth day after treatment, the total TCM syndrome score in both test group and positive drug group was lower than that in the placebo group(P<0.05). There was no significant difference in the incidence of adverse events between three groups and none of them experienced any serious adverse events related to the study drug. The results indicated that Regan Syrup could shorten the onset time of antipyretic effect, reduce the time of fever resolution, alleviate the symptoms such as sore throat and fever caused by wind-heat cold, reduce the total score of Chinese medicine symptoms, and improve the clinical recovery rate with good safety.

This study aimed to evaluate the cost-effectiveness of Chaiyin Granules compared with Oseltamivir Phosphate Capsules in the treatment of influenza(exogenous wind-heat syndrome). Based on a randomized, double-blind, positive drug parallel control clinical trial, this study evaluated the pharmacoeconomics of Chaiyin Granules with cost-effectiveness analysis method. A total of 116 patients with influenza from eight hospitals(grade Ⅱ level A above) in 6 cities were selected in this study, including 78 cases in the experimental group with Chaiyin Granules and Oseltamivir Phosphate Capsules placebo, and 38 cases in the control group with Oseltamivir Phosphate Capsules and Chaiyin Granules placebo. The total cost of this study included direct medical cost, direct non-medical cost, and indirect cost. The remission time of clinical symptoms, cure time/cure rate, antipyretic onset time/complete antipyretic time, viral nucleic acid negative rate, and traditional Chinese medicine(TCM) syndrome curative effect were selected as the effect indicators for cost-effectiveness analysis. Four-quadrant diagram was used to estimate the incremental cost-effectiveness ratio. The results showed that Chaiyin Granules were not inferior to Oseltamivir Phosphate Capsules in the remission time of clinical symptoms of influenza(3.1 d vs 2.9 d, P=0.360, non-inferiority margin was 0.5 d). Compared with Oseltamivir Phosphate Capsules, Chaiyin Granules would delay the remission time of clinic symptoms of influenza for 1 d, but could save 213.9 yuan. 1 d delay in cure time could save 149.3 yuan; 1% reduction in the cure rate could save 8.2 yuan; 1 d delay in antipyretic onset time could save 295.4 yuan; 1 d delay in complete antipyretic time could save 114.3 yuan; 1% reduction in the 5-day cure rate of TCM syndrome could save 19.2 yuan. Different from other indicators, there was no statistically significant difference between two groups in the effect of negative conversion rate of viral nucleic acid, but the cost was lower and the effect was superior, and the pharmacoeconomics was not different from that of Oseltamivir Phosphate Capsules in the field of influenza treatment.

As an effective antipyretic medicine,Indigo Naturalis has a long history of application in the field of Chinese medicine.The content of organics,mainly indigo and indirubin,is about 10%. However,the active ingredients and mechanism of its antipyretic effect have not yet been fully elucidated. In view of this,they were investigated in this study with the rectal temperature change as an indicator and 2,4-dinitrophenol-induced fever rats as subjects. The content of PGE2 and c AMP in the hypothalamus and the serum levels of TNF-α,IL-1β and IL-6 were determined by ELISA. Moreover,the plasma samples of fever rats were analyzed by metabonomics in combination with UPLC-Q-TOF-MS for the exploration of potential biomarkers and the discussion on the antipyretic mechanism of Indigo Naturalis and its active ingredients. The results showed that the rising trend of rectal temperature in rats was suppressed 0. 5 h after the treatment with Indigo Naturalis,organic matter,indigo or indirubin as compared with the rats of model group( P < 0. 05),among which Indigo Naturalis and organic matter had better antipyretic effect. ELISA results showed that organic matter and indigo can inhibit the expression of PGE2 and c AMP( P<0. 01),while Indigo Naturalis and organic matter were effective in curbing the increase in TNF-α( P<0. 05). A total of 21 endogenous metabolites were identified from the plasma samples of the Indigo Naturalis,organic matter,indigo and indirubin groups,which were mainly involved in glycerophospholipid metabolism.

PURPOSE: Data are lacking on the association between the allergic rhinitis (AR) phenotype and sensitization to specific allergens or bronchial hyperresponsiveness (BHR) in children. We here investigated risk factors and comorbidities, including sensitization to specific allergens and BHR, for the AR phenotype by AR and its Impact on Asthma (ARIA) classification in a general population-based birth cohort study. METHODS: We enrolled 606 children aged 7 years from the Panel Study of Korean Children. The AR phenotype was assigned in accordance with the ARIA classification in children. Skin prick tests and Provocholine provocation test were performed. Risk factors and comorbidities for AR phenotypes were then analyzed. RESULTS: The prevalence of mild and moderate to severe AR in our study cohort was 37.2% and 8.8%, respectively. Recent use of analgesics or antipyretics and current cat ownership were associated with the risk of mild persistent AR. Sensitizations to Dermatophagoides Pteronyssinus (Der p), Japanese hop and cat were associated with moderate to severe persistent AR. Children with moderate to severe AR had a higher risk of current asthma and BHR compared to mild AR cases (adjusted odds ratio [aOR], 5.26; 95% confidence interval [CI], 1.77–15.62). Moderate to severe AR with allergic sensitization was associated with the highest risk of BHR (aOR, 11.77; 95% CI, 3.40–40.74). CONCLUSIONS: Moderate to severe-persistent AR is more closely related to respiratory comorbidities and sensitizations than mild AR. Stratifying the AR phenotype by ARIA classification may assist in disease management.

A combination of LC-MS technology and activity evaluation was used to identify the antipyretic ingredients in rhubarb. The rat model of fever was established with dried yeast and then was administered ethanol extract and different polar fractions of rhubarb. Next, the anal temperature of these rats was measured and recorded at 0.5, 1, 2, 3, 4 and 5 h after administration, and the inhibition rate of each part on the rise of body temperature was calculated. The inhibition rate is higher and the antipyretic effect is better. The chemical composition of the effective fraction was analyzed with UPLC-ESI-Orbitrap-MS/MS technology. Compared with the model group, the increase of body temperature of ethanol extract group all reduced at each measurement time especially after 3 h, and the inhibition rate were 38.7%(P<0.05), 78.2%(P<0.01) and 72.4%(P<0.01) at 3 h, 4 h, and 5 h after administration, respectively. Both n-butanol and water fraction showed some antipyretic activity in the early stage, with the inhibition rate of 28.1%(P<0.01) and 24.9%(P<0.05) at 1 h after administration, respectively, while other fractions were not active. Thirty-three and twelve compounds were identified from n-butanol and water fraction by LC-MS/MS analysis, respectively, including ten tannins, fifteen anthraquinone glycosides, four anthrone glycosides, one phenolic glycoside, one naphthaline derivative, one anthraquinone and one sucrose. These results revealed that rhubarb had antipyretic activity on rats, and tannin and anthraquinone glycosides were the main active ingredients inside.

To investigate the antipyretic effect of active components of Mahuang Decoction in febrile rats, and explore its correlation with pharmacokinetics at different time points. The feverished rat models were induced by dry yeast, and intragastrically administered with the effective components of Mahuang Decoction with different orthogonal compatibility ratios. At different time points after administration, body temperature was measured; blood was taken from orbital vena plexus, and the contents of interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α) in rat serum were determined with the kits. Combined with the pharmacokinetic data of the seven effective components in Mahuang Decoction, PK-PD(pharmacokinetics-pharmacodynamics) data fitting was conducted by using the analysis method of non-atrioventricular model, and then the pharmacodynamic parameters were calculated to determine the optimal binding model. The results showed that the effective components of Mahuang Decoction inhibited the release of heat-causing factors IL-6, IL-1β and TNF-α, and reduced the increase of body temperature. There was a significant lag between drug effect and blood drug concentration, which was consistent with Sigmoid-E_(max) model. The model fitting value showed a good correlation with mea-sured data, which could be used to evaluate and predict the correlation between PK and PD in Mahuang Decoction, and further applied to the multiple-indicator and multiple-effect study of PK-PD in other compound traditional Chinese medicines.

The antipyretic effects of Qingkailing soft capsules and hard capsules were compared based on metabonomics technology,so as to provide basis for clinical rational use and quality control evaluation of its preparations. By using ultra high performance liquid chromatography-linear ion trap/orbitrap high resolution mass spectrometry( UPLC-LTQ/Orbitrap),and multivariate tatistical methods such as principal component analysis( PCA),partial least squares-discriminate analysis( PLS-DA) and orthogonal signal correction partial least square discriminant analysis( OPLS-DA),the changes of plasma endogenous metabolites in rat fever model induced by dry yeast were studied,so as to look for biomarkers related to fever. Based on these results,the antipyretic effects of two types of Qingkailing preparations were compared. The results indicated that metabolic profiles of the experimental groups could be distinguished distinctly,and 8 endogenous metabolites showed differences as compared with the normal control group( P<0. 05),including nicotinic acid,choline,hippuric acid,phosphocholine,Lyso PC( 14 ∶ 0),Lyso PC [16 ∶ 1( 9 Z) ],Lyso PC( 18 ∶ 0) and Lyso PC [20 ∶ 3( 5 Z,8 Z,11 Z) ]. They could be regarded as biomarkers related to fever. Qingkailing soft capsule and hard capsule had different effects on the regulation of plasma metabolites in yeast-induced fever model rats. Qingkailing soft capsule had different degrees of callbacks on eight biomarkers,including significant callbacks on nicotinic acid( P<0. 05),hippuric acid( P< 0. 01),phosphocholine( P< 0. 05),and Lyso PC [20 ∶3( 5 Z,8 Z,11 Z) ]( P<0. 05),while hard capsule only had significant callbacks on nicotinic acid( P<0. 05),hippuric acid( P<0. 01),and phosphocholine( P< 0. 05),with no callbacks on choline,Lyso PC( 14 ∶ 0),Lyso PC [16 ∶ 1( 9 Z) ],Lyso PC( 18 ∶0),and Lyso PC [20 ∶3( 5 Z,8 Z,11 Z) ]. This indicated that Qingkailing soft capsule had better callback effect than hard capsule. In this study,Qingkailing soft capsules and hard capsules were used to intervene the changes of related biomarkers in yeast-induced fever rat models,and then the antipyretic effect and mechanism between these two kinds of capsules were compared. The two dosage forms played an antipyretic role mainly by regulating lipid metabolism and controlling inflammation. The callback effect of soft capsule on the potential biomarkers of lysophosphatidylcholine was significantly higher than that of hard capsule. The differences in antipyretic effect of Qingkailing soft capsule and hard capsule were expounded from the point of metabonomics,providing experimental data and theoretical basis for the selection of clinical dosage forms.

PURPOSE: To investigate caregivers' preference regarding fever management in the emergency department. METHODS: Between July 2011 and June 2014, we surveyed the preference in fever management by caregivers of febrile children aged 7 years or younger who visited the emergency department. The questionnaire consisted of the characteristics of the children and their caregivers, usefulness of tepid massage, and the caregivers' preference in fever management, in particular the combination of methods and the doses of antipyretics. RESULTS: Among a total of 161 children, 161 were enrolled in the study, with the mean age of 5.0 years. Of the caregivers, 64.6% were in their 30s and 50.9% were parents, and 70.2% and 24.2% reported that tepid massage was "very useful" and "a little useful," respectively. The most preferred combination of methods was "tepid massage, acetaminophen, and ibuprofen (50.9%; P < 0.001)." "Tepid massage and ibuprofen" was preferred to "tepid massage and acetaminophen (24.2% vs 7.5%)." The most preferred dose of antipyretics was 1 mL/kg/day (divided into 3 doses; 60.2%; P = 0.012), followed by 1 mL/kg/day (divided into 3 doses) plus 2 mL/dose (29.1%). CONCLUSION: Caregivers may recognize tepid massage as a useful fever management. The most preferred fever management was the combination of tepid massage, acetaminophen, and ibuprofen with a dose of 1 mL/kg/day.
