ABSTRACT
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 â ¡ 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.

Jingfang Granules have the effects of inducing sweating to releasing exterior, dispersing wind and dispelling dampness. Modern studies have demonstrated that it has antipyretic and antiviral activities. Therefore, this trial was conducted to evaluate the efficacy and safety of Jingfang Granules in the treatment of common cold(wind-cold syndrome). A total of 138 common cold(wind-cold syndrome) patients meeting the inclusion and exclusion criteria were randomly assigned into the experimental group(n=92) and the placebo group(n=46) at a ratio of 2â¶1 and respectively received Jingfang Granules and Jingfang Granules simulation agent. The treatment lasted for 5 d, and the follow-up time was 8 d. Recovery time was employed as the main indicator of efficacy. The median reco-very time of the experimental group was 3.33 d, shorter than that 7.00 d of the placebo group. The efficacy of the experimental group was better than that of the placebo group(P<0.000 1). The major symptom severity score-time AUC of the experimental group was 489.90±206.95, which was smaller than that of the placebo group(763.50±339.53). The recovery rate and marked effective rate of the experimental group were higher than those of the placebo group, The above outcomes were statistically significant between the two groups(P<0.05). The disappearance time and rate of single symptoms including aversion to cold, nasal congestion, runny nose, cough, headache, pharyngeal itching/pain, white sputum, and somatalgia also had significant differences between the two groups(P<0.05), indicating that Jingfang Granules had good performance in alleviating the above symptoms. During the study period, one case of the experimental group had a slight increase in serum creatinine, which returned to the normal level after re-examination. The incidence of adverse reactions was 1.10%, and no serious adverse reaction was found. The two groups had no significant difference in the incidence of adverse reactions. In conclusion, Jingfang Granules can significantly shorten the course of common cold(wind-cold syndrome) and quickly alleviate the clinical symptoms, demonstrating good safety and clinical advantages.

BACKGROUND: Gubenzhike recipe, a traditional Chinese herbal compound, was assumed to have a possible beneficial effect on COPD. This study was designed to elucidate the mechanism from the perspective of respiratory mucosal immunity. METHODS: COPD model was induced by exposure to cigarette smoke and LPS instillation in mice for 12 weeks. Animals were administered solution of Gubenzhike recipe by intragastric gavage daily for 4 weeks. After that, mice were sacrificed for lung function test and histological examination of lung tissues. The levels of IL-6 and IL-13 in serum, bronchoalveolar lavage fluid (BALF), and intestinal mucus were measured by ELISA. The KGF and KGFR in lung tissue were analysed by immunohistochemical staining, ELISA, and western blotting, and the mRNA expressions were assessed by PCR. γδT lymphocytes in the lungs were isolated and analysed by immunohistochemical staining and flow cytometry. RESULTS: Gubenzhike recipe improved the structure of airway and damage of lung tissue and also the respiratory status and lung function, reduced the content of IL-6 in serum and BALF and IL-13 in BALF and intestinal mucus, increased the proportion of γδT cells in lung tissue, and promoted the secretion of KGF and KGFR (P < 0.05). CONCLUSION: We for the first time demonstrated an experimental procedure for the isolation of γδT lymphocytes from lung tissue. This study suggested that Gubenzhike recipe could enhance the respiratory mucosal immunity which provided experimental evidence for its effects of reinforcing "wei qi" by means of strengthening vital qi, tonifying spleen and kidney, relieving cough, and reducing phlegm in TCM.
ABSTRACT
The formation of expert consensus statement is an indispensable part in the process of developing clinical practice guidelines. The Guidelines International Network believes that experts make group decisions for different stages and issues,and the process of gathering expert opinions is the process of reaching the consensus. GRADE system also requires that recommendations should be formed based on expert consensus in consideration of the risk and bias,patients' preferences and values,resources and other factors. At present,the main method for reaching consensus is the formal consensus method. According to the published clinical guidelines,most of them failed to report the specific methods and process of reaching expert consensus. Therefore,it is impossible to obtain an objective evaluation. This phenomenon is more common in the field of clinical practice guidelines of traditional Chinese medicine( TCM). There are two main reasons for this phenomenon. For one thing,the developers of the guidelines neglect the importance of transparency and objectivity in the implementation of expert consensus. For another,they know little about the methods and technical specifications for the formation of expert consensus. To solve them,based on the internationally recognized consensus-building methods,as well as the specific stages in the process of developing clinical practice guidelines of traditional Chinese medicine,it is of great significance to put forward the technical norms for TCM researchers to develop the expert consensus. This guide will provide detailed guidance for forming the expert consensus for TCM clinical practice guideline. This guideline has been approved and published by the Chinese Association of Traditional Chinese Medicine( No. T/CACM 1049-2017).

A Chinese medicine granule, Shu-Feng-Xuan-Fei (SFXF), is critical for viral clearance in early phase of influenza virus infection. In this study, 72 ICR mice were randomly divided into six groups: normal control group, virus control group, Oseltamivir group, low-dose SFXF, medium-dose SFXF, and high-dose SFXF. Mice were anesthetized and inoculated with 4LD50 of influenza virus A (H1N1) except normal control group. Oseltamivir group received 11.375 mg·kg(-1) ·d(-1) Oseltamivir Phosphate. SFXF 3.76, 1.88 and 0.94 g·kg(-1) ·d(-1) were administrated to mice in all SFXF groups. Each group was in equal dose of 0.2ml daily for 4 consecutive days. Mice were sacrificed and then total RNA was extracted in lung tissue. Some genes involved in T-cell-mediated immunity were selected by DNA microarray. These candidate genes were verified by Real-Time PCR and western immunoblotting. Compared with virus control group, in Toll-like receptor signaling pathway, 12 virus-altered genes were significantly reduced following medium-dose SFXF treatment. Eighteen antigen processing presentation-associated genes were upregulated by medium-dose SFXF. In the process of T cell receptor signaling pathway, 19 genes were downregulated by medium-dose SFXF treatment. On exploration into effector T cells activation and cytokines, all of altered genes in virus control group were reversed by medium-dose SFXF. Real-time PCR and western immunoblotting showed that the regulation of medium-dose SFXF in IL-4, IFN-γ, TNF-α, IL-1ß, TLR7, MyD88, p38, and JNK was superior to Oseltamivir and high-dose SFXF group. Therefore, SFXF granules could reduce influenza infected cells and activation of T cells.
ABSTRACT
OBJECTIVE: To observe effect of Shufeng Xuanfei Recipe (SXR) and Jiebiao Qingli Recipe (JQR) on mRNA and protein expressions of Toll-like receptor 7 (TLR7), myeloid differentiation factor 88 (MyD88), and nuclear factor-kappaB (NF-kappaB) in mice infected with influenza virus FM1. METHODS: One hundred and eight mice were randomly divided into nine groups, i.e., the normal control group, the model group, the Oseltamivir group (at the daily dose of 2.5 g/mL), the high dose SXR group (at the daily dose of 3.762 g/kg), the middle dose SXR group (at the daily dose of 1.881 g/kg), the low dose SXR group (at the daily dose of 0.941 g/kg), the high dose JQR group (at the daily dose of 4.368 g/kg), the middle dose JQR group (at the daily dose of 2.184 g/kg), and the low dose JQR group (at the daily dose of 1.092 g/kg), 12 in each group. All mice were mildly anesthetized by ether. Mice in the normal control group were treated by nasal drop of 0.05 mL normal saline, while mice in the rest groups were infected by nasal drop of 0.05 mL influenza virus strain FM1 (LD50). The successful modeling rate was 100%. All medication was performed by gastrogavage 2 h after infection. Distilled water was given by gastrogavage to mice in the normal control group and the model group at the daily dose of 0.2 mL, each time per day for 4 successive days. mRNA expressions of TLR7, MyD88, and NF-kappaB in the lung tissue were determined by Western blot. RESULTS: Compared with the normal control group, mRNA expressions of TLR7, MyD88, and NF-kappaB increased in the model group (P < 0.01). Compared with the model group, mRNA and protein expressions of TLR7, MyD88, and NF-kappaB decreased in the Oseltamivir group, the high, middle, and low dose SXR groups (P < 0.05, P < 0.01); mRNA and protein expressions of TLR7 and NF-kappaB decreased in the high and middle dose JQR groups (P < 0.05, P < 0.01); mRNA expressions of MyD88 decreased in the high and middle dose JQR groups (P < 0.05); protein expressions of MyD88 decreased in the middle dose JQR group (P < 0.05); protein expressions of TLR7 and NF-kappaB decreased in the low dose JQR group (P < 0.05). Compared with the Oseltamivir group, protein expressions of MyD88 decreased in the low dose SXR group (P < 0.05); protein expressions of NF-kappaB decreased in the middle and low dose SXR groups (P < 0.01); mRNA and protein expressions of TLR7 (P < 0.05, P < 0.01), and protein expressions of MyD88 (P < 0.01) decreased in the high, middle, and low dose JQR groups; mRNA and protein expressions of NF-kappaB decreased in the low dose JQR group (P < 0.05, P < 0.01). CONCLUSIONS: Each dose SXR and middle dose JQR could down-regulating the activity of NF-kappaB through adjusting MyD88 dependent TLR signal pathway, thus fighting against influenza virus. SXR was more effective than JQR.

OBJECTIVE: To investigate the regulation of two herbal anti-virus formulas on gene expression profile associated with natural killer cell (NK cell) mediated cytotoxicity in pneumonia mice infected with influenza virus. METHODS: According to random number table, 90 ICR mice were divided into nine groups with 10 mice in each group: normal group (N), model group (M), oseltamivir group (control group, C), low-dose, medium-dose and high-dose Shufeng Xuanfei formula groups (SL, SM, SH groups), and low-dose, medium-dose and high-dose Jiebiao Qingli formula groups (JL, JM, JH groups). The model of pneumonia was reproduced by nasal dropping influenza virus A (FM1) in mice. N group was given isotonic saline 0.05 ml in nasal drops. After 2 hours of model-building, C group was received 11.375 mg×kg⻹×d⻹ oseltamivir phosphate. Shufeng Xuanfei formula (mainly honeysuckle, forsythia and radix isatidis, etc.) with 3.76, 1.88 and 0.94 g×kg⻹×d were administrated to SH, SM and SL groups by gastric irrigation respectively. Jiebiao Qingli formula (mainly ephedra, gypsum, glycyrrhiza glabra, etc.) with 4.36, 2.18 and 1.09 g×kg⻹×d⻹ were administrated to JH, JM and JL groups by gastric irrigation respectively. In N and M groups, normal saline was administrated with gastric perfusion. Each group was in equal dose of 0.2 ml daily over a 4-day period. Total RNA in lung tissue of mice were extracted in each group, then gene chips were used to screen these RNA samples. Some genes involved NK cell mediated cytotoxicity were selected, with "I" representing of signal intensity. These candidate genes were verified by real-time fluorescent quantitation polymerase chain reaction (PCR) and Western blotting. RESULTS: In the pathway of NK cell mediated cytotoxicity, M group up-regulated 43 genes expression, and 36, 29, 22, 21, 20 and 10 genes showed down-regulation in SM, JM, SL, JH, SH and JL groups, respectively. Apart from gene co-expression network in SH, SL, JH, JM and JL, SM also expressed other differential genes which SH, SL, JH, JM and JL did not. So medium-does Shufeng Xuanfei formula had the most significant regulation in gene expression of NK cell mediated cytotoxicity. By real-time PCR and Western blotting experiments showed that compared with the M group, mRNA and protein expression of tumor necrosis factor-α (TNF-α) in these two formula groups were significantly down-regulated, especially prominent in SM group and JM group (TNF-α mRNA: 1.07 ± 0.19, 1.19 ± 0.14 vs. 3.20 ± 0.56, both P<0.01). CONCLUSIONS: Influenza viral replication in host cell, which means influenza antigens exposure in infected cells as target cells. NK cells recognize and exert cell mediated cytotoxic function against influenza antigens. Genes associated with NK cell mediated cytotoxicity in influenza infection were up-regulated. Shufeng Xuanfei and Jiebiao Qingli formulas could down-regulate these genes. The mechanism of down-regulated genes is that the number of influenza infected cells and NK cells activation decreases in treatment with two formulas.
