Skin wound healing outcome was assessed by measuring skin thickness, weight(quality) of the skin, and trans-epidermal water loss(TEWL). Expression of AQP3 mRNA and protein was assessed by reverse transcriotion polymerase chain reaction(RT-PCR)and immunoblotting, respectively.RESULTS: Yupingfeng granule treatment resulted in significant acceleration of wound healing with63.64% efficiency, which was significantly higher than that of placebo granule treatment(31.82%,P < 0.01 by Wilcoxon Rank-sum test). Skin thickness, weight of the wounded skin, and TEWL were significantly higher in the AD models compared to that of normal animals. Treatment with Yupingfeng granules resulted in significant decrease in skin thickness [(937 ± 31) vs(360 ± 21) μm, P < 0.01],weight of the wounded skin [(42 ± 4) vs(24 ± 5)mg, P < 0.01], and TEWL [(30 ± 4) vs(13 ± 4) g·h^(-1)·m-2, P < 0.01]. Yupingfeng granules also significantly down-regulated mRNA and protein expression of AQP3 in the animal models.CONCLUSION: Our findings suggested that Yupingfeng granules could be used in AD treatment.展开更多

METHODS： Eighty male Wistar rats of sanitary degree were divided randomly into four groups： nor- mal group, model group, treatment group 1, treatment group 2. Besides the rats in the normal group, all the rats in other 3 groups were prepared as spleen deficiency model. The treatment group 1 were treated with Sijunzi decoction and the treat- ment group 2 were treated with Yupingfeng powder. After treatment for 6 weeks, perfusion was given and the brain was taken for detection of the ex- pression of the relevant DNAs of JAK-STAT signal pathwayofthe brain in SD rats bygene chip method. RESULTS： Spleen deficiency could lead to increase expression of JAKI, STATI and Interleukin 4 （IL-4） in the brain, but the decrease expression of Suppres- sor of cytokine signaling I （SOCSI）, prolactin recep- tor （PRLR） and binding protein 3 （GATA 3）. Sijunzi decoction could increase expression of STAT3, Pro- lactin （PRL） and GATA3, but decrease expression of JAKI, STAT, STAT4, Interleukin 10 receptor, alpha （ILIORA）, Coagulation factor II （F2）, PRLR, MAD homolog 3 （SMAD3） and IL-4. Yupingfeng powder could decrease expression of JAKI, STATI, STAT4, SOCS4_ predicted, Epidermal growth factor receptor （EGFR）, PRLR, High mobility group AT-hook I （HMGAI 0）, IL-4. CONCLUSION： Sijunzi decoction and Yupingfeng powder can improve immune function of the rat through influencing the genetic expression of JAK-STAT signal pathway.展开更多

Methods: A total of 58 cases of nasopharyngeal carcinoma were divided into two groups, 30 cases in the treatment group, 28 cases in the control group. Patients in two groups were treated with synchronous radiotherapy and chemotherapy treatment, the treatment group was treated with the Yupingfeng granules through oral administration, 10 g/time, tid for 2 courses. The serum Foxp3+ Treg markers of each group were detected by flow cytometry assay before treatment and after treatment, and the level of HA in serum was detected by radio immunoassay. Results: After radiotherapy and chemotherapy, the contents of Foxp3+ Treg and HA were significantly decreased in two groups(P<0.05), and the decrease of treatment group was more significantly(P<0.01). Correlation analysis showed positive correlation between Foxp3+ Treg and HA(P<0.05). After treatment, the incidence of side effects in two groups was significantly decreased. And there was significant difference between two groups(P<0.05). Conclusions: Combined chemotherapy and radiotherapy with Yupingfeng treatment can decrease the levles of Foxp3+ Treg and HA in nasopharyngeal carcinoma patients. Yupingfeng can also effectively reduce the side effect due to radiation and chemotherapy.展开更多

There have been studies investigating the treatment efficacy of Yupingfeng San, alone or in combination with other ingredients, in AR, though few have studied the potential mechanisms of these drugs. In the present study, we measured the effects of Jiawei Yupingfeng(JWYPF), a traditional Chinese medicine formula, on mice with ovalbumin-induced AR and explored its underlying mechanism of action.Methods: Forty BALB/c mice were randomly divided into normal control, allergy control and two treatment groups of ten mice each. In the normal control group, mice were sensitized and challenged with saline. The mice in the allergy control and treatment groups were sensitized and challenged with ovalbumin and aluminum hydroxide gel. The treatments of JWYPF and Nasonex were administered intranasally in the AR mice for one week. Several signs of allergic inflammation, such as nasal eosinophils and inflammatory cytokines, were measured to determine the underlying mechanisms.Results: Mice in the JWYPF and Nasonex groups had significantly lower AR symptom scores than those in the allergy control group(the mean differences between JWYPF and the allergy control, and Nasonex and the allergy control were -2.00 ± 0.35 and -2.40 ± 0.32). After treatment with JWYPF and Nasonex, the levels of ovalbumin-specific Ig E and histamine were significantly reduced, as were the levels of interlukin-4 and transforming growth factor-b, while interferon-c levels were increased(all P < 0.0001,vs. allergy control). These two treatments also significantly inhibited eosinophil and mast cell infiltration into the nasal cavity but were not statistically different from one-another.Conclusion: JWYPF has a potential therapeutic effect on AR via adjusting the rebalance of T helper 1 and T helper 2.展开更多

[Methods]First,90 mice in the protective group were injected with cyclophosphamide to replicate the chronic immunosuppressive model,and observe the protective effects of different doses of YPF-P on the spleen; 120 mice in the recovery group were injected with cyclophosphamide continuously to replicate the acute immune injury model,to observe the effects of YPF-P on spleen recovery. Besides,YPF-P positive control group was established to observe its effects on the spleen structure and function of normal mice. Testing indicators include spleen morphology and tissue structure,body mass,and spleen index. [Results]In the protective group and the recovery group,the spleen volume of the mice with different YPF-P doses increased significantly,and lymphocytes proliferated,showing obvious structural compensation and repair,and showing a dose-effect relationship. In the positive control group,the spleen function of the normal mice was significantly enhanced,and the spleen lymphoid tissue showed significant orderly proliferation. [Conclusions]Yupingfeng polysaccharides can effectively protect the function and structure of spleen,improve acute and chronic immune damage induced by cyclophosphamide,greatly promote the recovery of spleen structure and function after immune injury,and also can significant enhance the spleen structure and function of normal mice.展开更多

[Method] Taking immunosuppressive mice induced by 80 mg/kg cyclophosphamide as test animal model, effects of different doses （100,200 and 400 mg/kg） of YPF-P on spleen index, serum IL-2 and IFN-γ levels of mice were studied. [ Result] High dose of YPF-P （400 mg/kg） could improve the spleen index of immunosuppressive mice （P 〈0.05）. YPF-P could enhance serum IL-2 and IFN-γ levels of immunosuppressive mice, and the effects in middle-dose group and low-dose group were better. YPF-P could significantly increase serum IL-2 level of normal mice （ P 〈 0.01 ）, but it had no significant effect on serum IFN-γ level of normal mice. [ Conclusion] The research provides an experimental basis for clinical application of YPF-P.展开更多

Methods： A rat chronic bronchitis （CB） model was developed using lipopolysaccharide （LPS） combined with bacillus Calmette Guerin （BCG）. YPF, simple recipe Astragalus membranaceus （Fisch.） Bge （AM） and Astragalus membranaceus （Fisch.） Bge plus rhizome of Atractylodes macrocepha/a Koidz （AM＋RA） decoction were administered （intragastric administration, once a day for 21 days） to rats, to prevent and treat CB. Immunoregulatory and anti-inflammatory effects of YPF, AM and AM＋RA were tested by serum pharmacology in vitro on splenic lymphocytes of normal rats and alveolar macrophages of CB rats. Results： Inflammation in the pulmonary tissue and the bronchus of CB rats was significantly reduced in the YPF-treatment groups, AM and AM＋RA groups demonstrating the efficacy of YPF. Serum samples collected at different times from rats after administration of YPF, AM and AM＋RA demonstrated increased proliferation of splenic lymphocytes with area under the effect curve （AUE） of 552.6%, 336.3% and 452.0%, respectively. Treatment of alveolar macrophages with serum samples in YPF, AM or AM＋RA group inhibited interleukin-8 （IL-8） in the cell culture media, and the effect was much better in the YPF group compared with AM or AM＋RA group, with a higher maximal effect （Emax, P〈0.05） and larger AUE （P〈0.01 and P〈0.05）. Moreover, serum from rats treated with AM or AM＋RA had similar efficacy, while the efficiency was lower than that treated with YPF. Conclusion： YPF demonstrated anti-inflammatory and immunoregulatory effects in a rat model of CB, and time- dependent relationships were demonstrated in vitro.展开更多

文摘OBJECTIVE: To investigate effect of Yupingfeng granules, prepared with Chinese Medicines, on the wound healing and on the expression of aquaporin3(AQP3) and the skin barrier in the animal models of atopic dermatitis(AD).METHODS: Acute skin lesions of AD models were prepared using 2,4-dinitrochlorobenzo(DNCB) in mice and animals were treated with either Yupingfeng granules or placebo for two weeks. Skin wound healing outcome was assessed by measuring skin thickness, weight(quality) of the skin, and trans-epidermal water loss(TEWL). Expression of AQP3 mRNA and protein was assessed by reverse transcriotion polymerase chain reaction(RT-PCR)and immunoblotting, respectively.RESULTS: Yupingfeng granule treatment resulted in significant acceleration of wound healing with63.64% efficiency, which was significantly higher than that of placebo granule treatment(31.82%,P < 0.01 by Wilcoxon Rank-sum test). Skin thickness, weight of the wounded skin, and TEWL were significantly higher in the AD models compared to that of normal animals. Treatment with Yupingfeng granules resulted in significant decrease in skin thickness [(937 ± 31) vs(360 ± 21) μm, P < 0.01],weight of the wounded skin [(42 ± 4) vs(24 ± 5)mg, P < 0.01], and TEWL [(30 ± 4) vs(13 ± 4) g·h^(-1)·m-2, P < 0.01].

文摘OBJECTIVE： To observe the influence of Sijunzi decoction and Yupingfeng powder on the expression of the relevant DNAs of janus kinase （JAK）-signal transducer and activator of transcription （STAT） sig- nal pathway of the brain in spleen-deficiency mod- el rats. METHODS： Eighty male Wistar rats of sanitary degree were divided randomly into four groups： nor- mal group, model group, treatment group 1, treatment group 2. Besides the rats in the normal group, all the rats in other 3 groups were prepared as spleen deficiency model. The treatment group 1 were treated with Sijunzi decoction and the treat- ment group 2 were treated with Yupingfeng powder. After treatment for 6 weeks, perfusion was given and the brain was taken for detection of the ex- pression of the relevant DNAs of JAK-STAT signal pathwayofthe brain in SD rats bygene chip method. RESULTS： Spleen deficiency could lead to increase expression of JAKI, STATI and Interleukin 4 （IL-4） in the brain, but the decrease expression of Suppres- sor of cytokine signaling I （SOCSI）, prolactin recep- tor （PRLR） and binding protein 3 （GATA 3）. Sijunzi decoction could increase expression of STAT3, Pro- lactin （PRL） and GATA3, but decrease expression of JAKI, STAT, STAT4, Interleukin 10 receptor, alpha （ILIORA）, Coagulation factor II （F2）, PRLR, MAD homolog 3 （SMAD3） and IL-4. Yupingfeng powder could decrease expression of JAKI, STATI, STAT4, SOCS4_ predicted, Epidermal growth factor receptor （EGFR）, PRLR, High mobility group AT-hook I （HMGAI 0）, IL-4. CONCLUSION： Sijunzi decoction and Yupingfeng powder can improve immune function of the rat through influencing the genetic expression of JAK-STAT signal pathway.

文摘Objective: Chinese medicine has the potential to modulate allergic rhinitis(AR). There have been studies investigating the treatment efficacy of Yupingfeng San, alone or in combination with other ingredients, in AR, though few have studied the potential mechanisms of these drugs. In the present study, we measured the effects of Jiawei Yupingfeng(JWYPF), a traditional Chinese medicine formula, on mice with ovalbumin-induced AR and explored its underlying mechanism of action.Methods: Forty BALB/c mice were randomly divided into normal control, allergy control and two treatment groups of ten mice each. In the normal control group, mice were sensitized and challenged with saline. The mice in the allergy control and treatment groups were sensitized and challenged with ovalbumin and aluminum hydroxide gel. The treatments of JWYPF and Nasonex were administered intranasally in the AR mice for one week. Several signs of allergic inflammation, such as nasal eosinophils and inflammatory cytokines, were measured to determine the underlying mechanisms.Results: Mice in the JWYPF and Nasonex groups had significantly lower AR symptom scores than those in the allergy control group(the mean differences between JWYPF and the allergy control, and Nasonex and the allergy control were -2.00 ± 0.35 and -2.40 ± 0.32). After treatment with JWYPF and Nasonex, the levels of ovalbumin-specific Ig E and histamine were significantly reduced, as were the levels of interlukin-4 and transforming growth factor-b, while interferon-c levels were increased(all P < 0.0001,vs. allergy control). These two treatments also significantly inhibited eosinophil and mast cell infiltration into the nasal cavity but were not statistically different from one-another.Conclusion: JWYPF has a potential therapeutic effect on AR via adjusting the rebalance of T helper 1 and T helper 2.

文摘[Objectives] To study the protective and recovery effects of Yupingfeng polysaccharides( YPF-P) on spleen tissue structure of acute and chronic immunocompromised mice. [Methods]First,90 mice in the protective group were injected with cyclophosphamide to replicate the chronic immunosuppressive model,and observe the protective effects of different doses of YPF-P on the spleen; 120 mice in the recovery group were injected with cyclophosphamide continuously to replicate the acute immune injury model,to observe the effects of YPF-P on spleen recovery. Besides,YPF-P positive control group was established to observe its effects on the spleen structure and function of normal mice. Testing indicators include spleen morphology and tissue structure,body mass,and spleen index. [Results]In the protective group and the recovery group,the spleen volume of the mice with different YPF-P doses increased significantly,and lymphocytes proliferated,showing obvious structural compensation and repair,and showing a dose-effect relationship. In the positive control group,the spleen function of the normal mice was significantly enhanced,and the spleen lymphoid tissue showed significant orderly proliferation. [Conclusions]Yupingfeng polysaccharides can effectively protect the function and structure of spleen,improve acute and chronic immune damage induced by cyclophosphamide,greatly promote the recovery of spleen structure and function after immune injury,and also can significant enhance the spleen structure and function of normal mice.

文摘Objective： To investigate the anti-inflammatory and immunoregulatory effects of Yupingfeng , Powder and its components in rats. Methods： A rat chronic bronchitis （CB） model was developed using lipopolysaccharide （LPS） combined with bacillus Calmette Guerin （BCG）. YPF, simple recipe Astragalus membranaceus （Fisch.） Bge （AM） and Astragalus membranaceus （Fisch.） Bge plus rhizome of Atractylodes macrocepha/a Koidz （AM＋RA） decoction were administered （intragastric administration, once a day for 21 days） to rats, to prevent and treat CB. Immunoregulatory and anti-inflammatory effects of YPF, AM and AM＋RA were tested by serum pharmacology in vitro on splenic lymphocytes of normal rats and alveolar macrophages of CB rats. Results： Inflammation in the pulmonary tissue and the bronchus of CB rats was significantly reduced in the YPF-treatment groups, AM and AM＋RA groups demonstrating the efficacy of YPF. Serum samples collected at different times from rats after administration of YPF, AM and AM＋RA demonstrated increased proliferation of splenic lymphocytes with area under the effect curve （AUE） of 552.6%, 336.3% and 452.0%, respectively. Treatment of alveolar macrophages with serum samples in YPF, AM or AM＋RA group inhibited interleukin-8 （IL-8） in the cell culture media, and the effect was much better in the YPF group compared with AM or AM＋RA group, with a higher maximal effect （Emax, P〈0.05） and larger AUE （P〈0.01 and P〈0.05）. Moreover, serum from rats treated with AM or AM＋RA had similar efficacy, while the efficiency was lower than that treated with YPF. Conclusion： YPF demonstrated anti-inflammatory and immunoregulatory effects in a rat model of CB, and time- dependent relationships were demonstrated in vitro.

文摘Background Yupingfeng,a traditional Chinese complex prescription,has been used efficaciously in China for the cure and prevention of inflammatory diseases related to immunodeficiency such as allergic rhinitis and chronic bronchitis.However,the active components of this prescription remain unclear.The present study focused on investigating the antiinflammatory and immunoregulatory effects of the glucosidic extract from Yupingfeng.Methods We tested animal models for ear swelling induced by dimethylbenzene in mice;palm swelling induced by carregeenin and granuloma induced by cotton pellet in rats;level of haemolysin,antibody generation by the splenic cells,delayed hypersensitivity and T cell subsets in spleen of immunosuppressed mice.Results Glucosidic extract of 24 mg/kg,48 mg/kg and 96 mg/kg significantly inhibited mice's ear swelling induced by dimethylbenzene.Similarly glucosidic extract of 16 mg/kg,32 mg/kg and 64 mg/kg inhibited rats'palm swelling induced by carregeenin and granuloma induced by cotton pellet.Glucosidic extract of 24 mg/kg,48 mg/kg and 96 mg/kg improved the IgM level in serum and level of haemolysin in splenocytes in mice immunosuppressed by cyclophosphamide.Delayed hypersensitivity in mice suppressed by cyclophosphamide was enhanced by glucosidic extract of 24 mg/kg,48 mg/kg and 96 mg/kg.These results suggested that Yupingfeng could recover humoral and cellular immune function in mice with immunosuppression.Glucosidic extract of 48 mg/kg and 96 mg/kg significantly resisted the immunosuppressive mice ear swelling and maintained it at nearly normal level.The enhanced,delayed hypersensitivity actions of glucosidic extract,suppressed by cyclophosphamide,might be brought about by inducing TH cell and regulating T lymphocytes subset.Conclusions The glucosidic extract from Yupingfeng has antiinflammatory and immunoregulation action,suggesting that these glucosides are the principal active components of the traditional Chinese prescription Yupingfeng.
