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

文摘To observe the impact of Yupingfengsan Oral Liquid on the expression of IL-4 and IFN-<em>γ</em> in AR mice’s serum and expression level of nuclear factor—<em>κ</em>B (NF-<em>κ</em>B) protein and gene in nasal mucosa. <strong>Method:</strong> Forty BALB/c mice were randomly divided into the normal group, model group, Yupingfengsan Oral Liquid group (6 g/kg) and Loratadine group, with 10 mice per group. AR mice model was established by OVA, and IL-4 and IFN-<em>γ</em> contents can be measured with ELISA. The morphological changes of nasal mucosa were observed by hematoxylin eosin (HE) staining and NF-<em>κ</em>B expression in the nasal mucosa of mice was tested with Real-Time PCR and Western blot. <strong>Results:</strong> Compared with the model group, the nasal symptoms in the Yupingfengsan Oral Liquid group and Loratadine group were obviously relieved. HE staining showed that there was a little inflammatory cell infiltration in the nasal mucosa of Yupingfengsan Oral Liquid group and Loratadine group and it was significantly reduced when compared with the model group. IL-4 level in the serum and expression of NF-<em>κ</em>B protein and gene in the nasal mucosa was consistent and it was decreased when compared with the model group (P < 0.01), but the IFN-<em>γ</em> level in the serum was increased (P < 0.01). <strong>Conclusion:</strong> Yupingfengsan Oral Liquid can improve the clinical symptoms and histopathological manifestations of AR mice sensitized by OVA, inhibit the NF-<em>κ</em>B expression, balance the percentage of Th1/Th2 cells, increase the IFN-<em>γ</em> level in the serum and decrease the IL-4 level.
