Pudilan Xiaoyan oral liquid regulates tissue inflammation and apoptosis in mice with influenza virus pneumonia

Background:The influenza A virus is the primary cause of respiratory infections and poses a global health risk.Pudilan Xiaoyan oral liquid(PDL)exhibits anti-inflammatory and immunomodulatory properties.PDL is commonly employed in clinical practice to manage upper respiratory tract infections.However,there is still much to uncover regarding its potential therapeutic mechanism.Methods:Institute of cancer research mice were infected with influenza A virus via nasal drip.The general state of the mice,lung index,and lung index inhibition rate were used to evaluate the efficacy of PDL.Enzyme-linked immunosorbent assay,western blotting,and immunohistochemistry were used to observe the presence of proteins and cytokines in the lung tissue.Apoptosis was evaluated using the TUNEL assay.Results:PDL improved the mental state of influenza A virus-infected mice,reduced the lung index,and inhibited viral replication.The expression of interleukin-1βand tumor necrosis factor-αwere decreased,whereas the expression of interleukin-10 in the lung tissue was increased due to PDL treatment.In addition,PDL treatment modulated Toll-like receptor 4 and MyD88 expressions in the lung tissues.PDL significantly reduced apoptosis and decreased cleaved caspase-3 and PARP levels,whereas increased B-cell lymphoma-2 expression in the lung tissue.Notably,the moderate-dose group of PDL exhibited a more pronounced effect.These findings indicate that PDL exerts a protective effect against pneumonia injury in influenza A virus-infected mice.Conclusion:PDL inhibited the inflammatory response and regulated apoptosis by regulating Toll-like receptor 4 and MyD88 protein expressions,thereby protecting the lung tissue from viral infection-induced lung tissue injury.

Efficacy evaluation of Shenlan oral liquid in the treatment of experimental thrombosis and hyperlipidemia

Objective:To explore the therapeutic effect of Shenlan oral liquid on thrombosis rats and hyperlipidemia mice.Methods:Male Wistar rats were divided into four groups randomly:the control group,the Shenlan oral liquid groups(high dosage and low dosage),and the positive control group.Rats in the control group were treated with dd water intragastriclly;in the positive control group,rats were treated intragastric with aspirin.Rats were treated with different drugs intragastric for continuous 22 d.In the hyperlipidemia experiment,mice were fed with high-fat diet to induce hyperlipidemia model mice,then randomly divided into five groups;the control group,the model group,the atorvastatin calcium positive control group,and the Shenlan oral liquid groups(high dosage and low dosage).The serum lipid and body weight changes of mice were observed after 6 weeks.Animals in Shenlan oral liquid high and low dosage were treated intragastric with six times and double the clinical dose.Results:After treatment,the mix blocking rate and average blocking rate of the vascular after electrical stimulation were obviously reduced in aspirin group,and Shenlan oral liquid high and low dose groups(P<0.05 or P<0.01).The maximum aggregation rate was significantly lower than that of control group(P<0.05 or P<0.01),and the normal coagulation function was not affected.In the treatment of hyperlipidemia,the effects of Shenlan oral liquid were measured on the total cholesterol(TC),triacylglycerol(total triglyceride,TG),low density lipoprotein(LDL-C)and high-density lipoprotein(HDL-C)with the hyperlipidemia mice.After 2 weeks administration,the serum TG level of Shenlan oral liquid high-dose group decreased compared with the model group.The TG level of serum in Shenlan oral liquid high-dose group significantly decreased compared with the model group from the fourth week(P<0.05).After 6 weeks administration,Shenlan oral liquid high-dose and low-dose group and positive drugs reached to the same therapeutic effect.Compared with model group,serum TG level was significantly decreased(P<0.05 or P<0.01).Conclusion:Shenlan oral liquid can decrease the thrombosis formation in rats and inhibit the lipid level in blood in hyperlipidemia mice.

Pharmacodynamic study in multi-animal models on the efficacy and optimal dosage of antiviral oral liquid for children

Antiviral Oral Liquid(AOL)is an adult medicine in the Chinese Pharmacopoeia used to treat upper respiratory infections such as influenza.It has shown promising clinical efficacy in relieving flu-like symptoms such as fever,inflammation,and pharyngalgia both in adults and children.However,the instruction manual does not specify the exact usage and dosage of AOL for children.In this article,we set 6 dosage ranges:0.2,0.5,0.7,0.9,1.1,1.4 mL/kg/d,according to its dosage for adults and the conversion method between adult and children dosage.And six animal models were used to evaluate the effectiveness of AOL in different doses.The results indicated that AOL could reduce the lung index,virus load,and expression of proinflammatory cytokines in the lung.AOL could improve pathological changes and prolong the survival time of mice infected by the Influenza A virus(H1N1)A/PR/8/34 strains at 0.5–0.9 mL/kg/d concentrations in different degrees.The four dose groups of 0.7–1.4 mL/kg/d could significantly inhibit the ear shell swelling caused by xylene and reduce the rabbit body temperature induced by lipopolysaccharide(P<0.01,P<0.05).All the five dosage groups of 0.2–1.1 mL/kg/d could inhibit the increase of peritoneal capillary permeability induced by glacial acetic acid(P<0.01).AOL at 0.7 and 0.9 mL/kg/d reduced the painful writhing times in young mice induced by glacial acetic(P<0.01).These results indicated that the optimal dose of AOL in antiviral,antipyretic,anti-inflammatory,and analgesic effects is 0.7 mL/kg/d.

The results showed that the body mass gain and organ indexes differed insignificantly among different groups （P〉0.05）. No significant differences were found in the routine blood indexes, serum ALT activity, albumin content, creatinine content and urea content among different groups before and after the experiment （P〉0.05）. After the administration, the head, liver, spleen, lung and kidney of the chickens showed no obvious abnormalities. In shod, Manhuning oral liquid had little impact on the physiological and biochemical indexes and had no toxic effects on the head, liver, spleen, lung and kidney of chickens, and it is a low-toxicity safe veterinary drug preparation.

HPLC Fingerprint with Multi-components Analysis for Quality Consistency Evaluation of Traditional Chinese Medicine Si-Mo-Tang Oral Liquid Preparation

Si-Mo-Tang（SMT） oral liquid preparation, a traditional Chinese medicine, was prepared from four crude herbal drugs, Fructus Aurantii Submaturus, Radix Aucklandiae, Semen Arecae and Radix Linderae Aggregatae. A combinative method using HPLC fingerprint and quantitative analysis was developed and validated for quality consistency evaluation of SMT. Individual HPLC chromatograms were evaluated against the mean chromatogram generated via a similarity evaluation computer program. Data from chromatographic fingerprints were also processed with principal component analysis（PCA） and hierarchical cluster analysis（HCA）. Additionally, six components （naringin, isonaringin, hesperidin, neohesperidin, norisoboldine and potassium sorbate） in SMT were simultaneously determined to interpret the quality consistency. For fingerprint analysis, 20 peaks were selected as the characteristic peaks to evaluate the similarities of 26 SMT collected from different manufacturers. Among the 20 characteristic peaks, 10 peaks were assigned to be naringin, hesperidin, neohesperidin, isonaringin, neoeriocitrin, tangeretin, nobiletin, norisoboldine, 5-（ethoxymethyl）furan-2-carbaldehyde and potassium sorbate, respectively. The results of similarity analysis, PCA and HCA, indicate that the samples from different manufacturers were consistent with each other in composition. The results from the quantitative data show that the contents of six compounds were significantly different in SMT oral liquid preparations from different manufacturers. The combinative method of chromatographic fingerprint with quantitative analysis developed here offered an efficient way for the quality consistency evaluation of the traditional Chinese medicine SMT.

Study on the Effects of Guiqi Oral Liquid (归芪口服液) in Promoting Recovery of Hematopoiesis in AcuteIrradiation Injured Mice

Objective： To explore the effects and possible mechanisms of Guiqi Oral Liquid （归芪口服液, GQOL） on the recovery of hematopoiesis in acute irradiation injured mice. Methods： The acute irradiation injured mice were randomly divided into 2 groups： the treated group and the control group, and also a normal control group was set up with 6 mice in it receiving no treatment. After the mice in the former two groups were irradiated by 6.0 Gy ^60Coγ-ray, every one of them was given 0.4 ml GQOL or saline in equal volume through a gastric tube twice a day for 14 days. On the 4th, 8th and 14th day after irradiation, the bone marrow mononuclear cells （BMMNC） and megakaryocytes in bone marrow tissues of the mice were counted, the proportion of hematopoietic tissues （by area） was measured, and the expression of adhesion molecules, CD44 and CD54, in bone marrow were estimated by immunochemistry. The colony forming unit of spleen （CFU-S） in the mice were counted on the 8th day after irradiation. Results： On the 4th, 8th, 14th day after irradiation, the count of BMMNC and megakaryocyte, and the proportion of hematopoietic tissues in the treated group were higher than those in the control group （P〈0.01 or P〈0.05）. CD44 and CD54 expression in the treated group were higher than those in the control group on the 4th and 8th day （P〈0.01）, but near normal on the 14th day （P〈0.01）. On the 8th day, CFU-S count in the treated group was higher than that in the control group （P〈0.01）. Conclusion： GQOL can regulate the expression of adhesion molecules, CD44 and CD54, in the bone marrow of the acute irradiation injured mice, which may be one of the mechanisms of GQOL in accelerating the early phase hematopoiesis recovery of mice.

Effect of Biejiajian Oral Liquid on the Expression of RAAS in Hepatic Fibrosis Rats

Objective: To study the effect of Biejiajian Oral Liquid (BOL) on the rennin angiotensin aldosterone system (RAAS) in plasma of hepatic fibrosis rats and in hepatic stellate cell (HSC) of normal rats. We explore the mechanism of BOL on inhibiting the activation of HSC and illustrate its mechanism of anti-hepatic fibrosis further. Methods: SD Rats were divided into 5 groups randomly: normal control group, model group, Enalapril group and BOL groups with different concentration (2.0 g/ml or 1.0 g/ml). Every group was administered with CCl4 and olive oil solution to induce hepatic fibrosis except normal one. Each group was treated with the respective drug for 5 weeks and then got the blood. The level of renin, angiotensin II and aldosterone in the plasma of liver fibrosis rats were detected by the radioimmunoassay. By using reverse transcription-polymerase chain reaction (RT-PCR) to measure the gene expression of the rennin, ACE, angiotensinogen, AT1R and ALD. The AT1R gene expression in normal HSC was determined by the immunohistochemical measurement. Results: BOL could effectively reduce the activity of the PRA, AngIIand ALD, which showed a significant effect on the inhibition of the AngII (P < 0.01). Meanwhile, compared with the normal control group, there was a notable inhibitory action on the PRA of HSC which was administrated by serum containing BOL (P < 0.05). And yet, drug applied group showed no difference with the model group for other factors of the RAAS. Conclusion: BOL can inhibit the expression of RAAS in the rat plasma and can inhibit the expression of the mRNA of renin in the normal HSC, which could be the mechanism of anti-hepatic fibrosis.

Objective: To observe the clinical therapeutic effects of Rehmannia Oral Liquid on the syndrome of heat accumulation with Yin consumption in intermediate or late esophagus cancer patients undergoing radiotherapy. Methods: The IFN-α, TNF-α, IL-1β and TGF-β1 levels in sera were determined by the method of ABC-WLISA before and after the treatment with Rehmannia Oral Liquid. At the same time, the observation was carried out on the patient's general condition, symptoms and signs, barium meal or CT examinations, and biopsy. Another 30 cases of esophagus cancer were treated singly with radiotherapy as the control group. Results: Rehmannia Oral Liquid could obviously improve the patient's general condition, and the symptoms and signs after radiotherapy. Based on the X-ray examination and biopsy, the short-term local control rate of the treatment group and the control group was 70.0% and 40.0% respectively, showing a significant difference (P<0.05). Before the treatment, the level of serum IFN-α of both cancer groups was lower and the levels of TNF-α, IL-1β and TGF-β1 were higher than that of normal group. After treatment, the level of IFN-α in both treatment group and control group increased significantly (P<0.01), and the treatment group improved more obviously than the control group (P<0.05). The level of TNF-α of both groups decreased significantly (P<0.01) after treatment, and the level of IL-1β decreased in treatment group and increased in control group without the significant difference as compared with that before treatment. The level of TGF-β1 was significantly increased in control group (P<0.05) and decreased in treatment group (P>0.05) after treatment. The difference between groups was significant (P<0.05). Conclusion: Rehmannia Oral Liquid can obviously reduce the radiotherapy reaction, improve the quality of life, and raise the therapeutic effects. The action mechanism of the Liquid may lie in balancing the cytokine network and regulating the disordered signal transmission.

Systematic Review and Meta-analysis of Biyuanshu Oral Liquid in the Treatment of Chronic Rhinosinusitis

[Objectives]The objective was to study the clinical efficacy and safety of Biyuanshu oral liquid in the treatment of chronic rhinosinusitis(CRS).[Methods]Randomized controlled trial was adopted to conduct scientific and standardized assessment on the risk of bias in the included papers.With overall effect and incidence of adverse reactions as indices,meta-analysis was performed,and sensitivity and safety analysis was conducted on the included literature.[Results]A total of 15 papers were included,involving 1489 patients.The efficiency of Biyuanshu oral liquid combined with Western medicine was better than that of Western medicine alone.[Conclusions]Biyuanshu oral liquid is safe and effective in treating chronic rhinosinusitis,and is suitable for patients who are not convenient for surgery.However,as the 15 papers included are all low in quality and there is a certain degree of publication bias,the objectivity of the results is affected to some extent.

Qingfei oral liquid downregulates TRPV1 expression to reduce airway inflammation and mucus hypersecretion injury caused by respiratory syncytial virus infection and asthma in mice

Objective:Qingfei oral liquid(QF),an experimental Chinese medicine prescription developed from the ancient priscription of traditional Chinese medicines Ma Xin Shi Gan decoction and Tingli Dazao Xie Fei decoction,has been effectively used since decades to treat patients with viral pneumonia and asthma.In our previous study,we had demonstrated that QF can significantly reduce airway hyperresponsiveness,hyperemia,lung tissue edema,inflammatory lung tissue infiltration in mice,airway mucus secretion,and peripheral airway collagen hyperplasia;however,its mechanism of action is unknown.Methods:Fifty 6–8-week-old male BALB/c mice were equally and randomly divided into five groups:the control,ovalbumin(OVA),OVA+respiratory syncytial virus(RSV),QF,and dexamethasone(Dxms)groups.The QF group was administered QF at 1.17 g·kg−1·d−1,the Dxms group received dexamethasone injections at 0.2 mg·kg−1·d−1,and the remaining groups were administered PBS.Inflammation in the lung tissue was assessed by hematoxylin and eosin(HE),periodic acid–Schiff(PAS),and Van Gieson staining.ELISA was used to evaluate the IL-13,IL-25,and IL-33 in the mice.Western blotting was used to examine changes in the proteins levels of transient receptor potential vanilloid-1(TRPV1)and mucin 5AC(MUC5AC)in the lung tissues of mice.Results:Histopathological evaluation revealed that the OVA and OVA+RSV groups exhibited lung tissue edema and inflammatory lung tissue infiltration in the HE staining and airway secretions in the PAS staining;collagen hyperplasia around the airway was increased in these two groups compared with the control group.The QF group exhibited significantly reduced lung tissue edema,inflammatory lung tissue infiltration,airway secretions,and collagen hyperplasia around the airway compared with the OVA+RSV group.We analyzed the serum levels of IL-13,IL-25,and IL-33 in the mice and found that these levels were higher in the OVA and OVA+RSV groups than in the control group(P<0.05 in the OVA group,P<0.01 in the OVA+RSV group).The QF group exhibited significantly decreased serum levels of IL-13,IL-25,and IL-33 compared with the OVA+RSV group(all P<0.05).The Dxms group also exhibited significant decreases in the serum levels of IL-13 and IL-33(all P<0.05)but no significant decrease in the serum levels of IL-25 compared with the RSV+OVA group.Finally,we examined the protein levels of TRPV1 and MUC5AC in the lung tissues of mice using Western blotting.After identifying RSV infection in the mice with asthma,the protein levels of TRPV1 and MUC5AC in the lung tissues of mice were significantly higher than those in the control group(P<0.05,P<0.01).We found that compared with RSV+OVA,QF can significantly downregulate the protein level of TRPV1;further,the protein level of MUC5AC was also significantly reduced(all P<0.001).Conclusion:QF can inhibit RSV replication and reduce airway inflammation and mucus hypersecretion injury caused by RSV infection and asthma,and its mechanism of action may be associated with the downregulation of TRPV1 expression and a decrease in airway mucus hypersecretion injury.
