A Study of the Treatment of Disfiguring Diseases in the “Qian Jin Fang”

Traditional Chinese medicine(TCM)has been passed down for more than 2,000 years.TCM beauty products driven by the principles of identification and treatment with various dosage forms and exhibit mild and safe efficacy are bound to become a main component of the beauty industry in the future.Xu once commented that“Qian Jin Fang”is different from the traditional prescription system,which emphasizes the use of medicines.In this paper,we mainly selected the prescriptions for the treatment of disfigurement diseases such as acne,scarring,black dryness,face hyperpigmentation,black mole,and rosacea from the article titled,“Upper Seven Orifices Disease-Facial Medicine IX”in the Bei Ji Qian Jin Yao Fang[1].By studying and analyzing the original composition of the formula,understanding the etiology and pathogenesis of the disease,and exploring the characteristics of the formula concerning the efficacy of TCM,their properties,flavors,and meridians,we summarized the characteristics of the Qian Jin Fang.It is based on the external treatment of disfigurement diseases,with a wide variety of drugs,flexibility,and accuracy.This method draws upon analogies while utilizing excipients and harmonizers to focus on the combined healing approach of treatment and nourishment.

Clinical Study on the Effectiveness of Xian Fang Huo Ming Yin for Treating Cutaneous Infections and Promoting Wound Healing in Patients with Perianal Abscess

Objective:To explore the effect of the Xian Fang Huo Ming Yin(XFHM)for treating cutaneous infections and promoting wound healing in patients with perianal abscesses.Methods:Sixty-one patients with perianal abscesses who were admitted to our hospital(Xinghua City People’s Hospital)from May 2022 to May 2023 were selected and randomly divided into two groups,a control group(30 cases)and a study group(31 cases).Both groups received surgical treatment.The control group received conventional treatment and warm water fumigation,sitz bath,and surgical dressing change after surgery,while the research group received XFHM based on the control group.XFHM was taken orally and replaced with warm water for fumigation and sitz bathing.Both groups received treatment for 4 weeks but discontinued sitz bathing after 2 weeks.Various clinical indicators between the two groups were compared.Results:The total clinical effective rate and wound recovery rate of the study group were higher than that of the control group.There were differences in the wound pain scores,surrounding tissue edema,and wound secretions at different time points.Both groups experienced wound pain.The scores of wound pain,surrounding tissue edema,and wound secretions of the study group were lower than those of the control group,7 and 14 days after surgery.The serum interleukin 6(IL-6),tumor necrosis factor-alpha(TNF-α)levels,and pH values of the study group were lower than those of the control group 10 days after surgery(P<0.05).Conclusion:The application of XFHM for treating cutaneous infections and promoting wound healing in patients with perianal abscesses improved the treatment outcome,alleviated clinical symptoms,and promoted healing.

Mu-Xiang-You-Fang protects PC12 cells against OGD/R-induced autophagy via AMPK/mTOR signaling pathway

OBJECTIVE Mu-Xiang-You-Fang(MXYF)is a classic prescription of Hui medicine,composed of five herbs,which has been used to treat ischemic stroke for many years.However,the potential pharmacological mecha⁃nisms of MXYF remain unclear.The present research is to investigate the neuroprotective effect of MXYF and its role in modulating autophagy via AMPK/mTOR signaling pathway in the PC12 oxygen-glucose deprivation and reperfusion(OGD/R)injury model.METHODS MXYF was extracted by supercritical CO2 fluid extraction apparatus.PC12 OGD/R injury model was established by oxygen-glucose deprivation for 2 h and reperfusion for 24 h.The effects of MXYF on the viability and cytotoxicity of PC12 cells were determined through cell counting kit(CCK-8)assay.Colorimetric method was performed to determine the LDH leakage rate.The calcium concentration was determined by chemical fluorescence method and the mitochondrial membrane potential was determined through flow cytometry.Monodansylcadaverine(MDC)staining was conducted to detect autophagosome formation.The expression of LC3,Beclin1,p62,p-AMPK,ULK1,p-mTOR and p-p70s6k proteins were determined by immunofluorescence and Western blotting analyses.RESULTS MXYF(1,2 and 4 mg·L^-1)could significantly increase the cell viability and mitochondrial membrane potential,while decreased the release of lactate dehydrogenase(LDH)and calcium concentration in PC12 cells.Mechanistic studies showed that MXYF reduced the LC3-II/LC3-I ratio and inhibited the expression of beclin1,p-AMPK and ULK1.In comparison,the expres⁃sion of p-mTOR,p-p70s6k and p62 were significantly enhanced.CONCLUSION MXYF inhibits autophagy after OGD/Rinduced PC12 cell injury through AMPK-mTOR pathway,thus MXYF might have therapeutic potential for treating the ischemic stroke.

Possible mechanisms associated with immune escape and apoptosis on anti-hepatocellular carcinoma effect of Mu Ji Fang granules

BACKGROUND Hepatocellular carcinoma(HCC)is one of the most common digestive system cancers with high mortality rates worldwide.The main ingredients in Mu Ji Fang Granules(MJF)are alkaloids,flavonoids,and polysaccharides.MJF has been used in the clinical treatment of hepatitis,cirrhosis and HCC for more than 30 years.Few previous studies have focused on the mechanism of MJF on tumor immunology in the treatment of HCC.AIM To explore the mechanism of action of MJF on tumor immunology in the treatment of HCC.METHODS The absorbable ingredients of MJF were identified using Molecule Network related to High Performance Liquid Chromatography-Electron Spray Ionization-Time of Flight-Mass Spectrometry,and hub potential anti-HCC targets were screened using network pharmacology and pathway enrichment analysis.Forty male mice were randomly divided into the Blank,Model,and MJF groups(1.8,5.4,and 10.8 g/kg/d)following 7 d of oral administration.Average body weight gain,spleen and thymus indices were calculated,tumor tissues were stained with hematoxylin and eosin,and Interferon gamma(IFN-γ),Tumor necrosis factorα(TNF-α),Interleukin-2,aspartate aminotransferase,alanine aminotransferase,alpha-fetoprotein(AFP),Fas,and FasL were measured by Enzyme-linked Immunosorbent Assay.Relevant mRNA expression of Bax and Bcl2 was evaluated by Real Time Quantitative PCR(RTqPCR)and protein expression of Transforming growth factorβ1(TGF-β1)and Mothers against decapentaplegic homolog(SMAD)4 was assessed by Western blotting.The HepG2 cell line was treated with 10 mg/mL,20 mg/mL,30 mg/mL,40 mg/mL of MJF,and another 3 groups were treated with TGF-β1 inhibitor(LY364947)and different doses of MJF.Relevant mRNA expression of TNF-α,IFN-γ,Bax and Bcl2 was evaluated by RT-qPCR and protein expression of TGF-β1,SMAD2,p-SMAD2,SMAD4,and SMAD7 was assessed by Western blotting.RESULTS It was shown that MJF improved body weight gain and tumor inhibition rate in H22 tumorbearing mice,protected immune organs and liver function,reduced the HCC indicator AFP,affected immunity and apoptosis,and up-regulated the TGF-β1/SMAD signaling pathway,by increasing the relative expression of TGF-β1,SMAD2,p-SMAD2 and SMAD4 and decreasing SMAD7,reducing immune factors TNF-αand IFN-γ,decreasing apoptosis cytokines Fas,FasL and Bcl2/Bax,and inhibiting the effect of LY364947 in HepG2 cells.CONCLUSION MJF inhibits HCC by activating the TGF-β1/SMAD signaling pathway,and affecting immune and apoptotic cytokines,which may be due to MJF adjusting immune escape and apoptosis.

Mechanism of Huatan Sanjie Fang in improving goiter in Graves'disease mice based on the Hippo signaling pathway

Objective:To explore the mechanism of Huatan Sanjie Fang(HTSJ)in regulating goiter in Graves'disease(GD)mice by detecting key factors of the Hippo signaling pathway.Methods:A mouse model of GD was established by injecting Ad-TSHR289 adenovirus into the bilateral quadriceps femoris of female mice.Successful mouse models were then randomly divided into a model group,methimazole(MMI)group,and HTSJ group,and fed with deionized water,MMI(4.5 mg/kg per day),and HTSJ(35.10 g/kg per day),respectively,for 10 weeks.Histopathological changes of the thyroid gland were subsequently observed by hematoxylin-eosin staining.Radioimmunoassay was used to detect serum total thyroxine(T4)and thyrotrophin-receptor antibody(TRAb)levels.The relative expression of mRNA of Mst1,YAP,and TAZ were detected by quantitative real-time polymerase chain reaction,while the protein expression of Mst1,YAP,TAZ,pMst1,and pYAP were detected by western blot.Results:After 10 weeks of drug intervention,goiter and other pathological changes in the HTSJ group significantly improved compared with the model group,and the levels of serum T4 and TRAb significantly decreased(P=.002,P<.001,respectively).Decreased mRNA expression of Mst1,YAP,and TAZ,the key factors of the Hippo signaling transduction pathway,was also observed(P=.002,P=.022,P<.001,respectively).In contrast,protein expression of Mst1(P=.046),pMst1(P=.026),and p YAP(P=.004)increased,while protein expression of YAP and TAZ decreased(P=.041,P<.001,respectively).Conclusion:HTSJ can effectively improve goiter in GD mice through the Hippo signaling pathway.

基于FXR-Srebp1c-FAS通路及CD36探讨祛痰活血方抗非酒精性脂肪性肝病的机制

目的 以内源性脂肪酸合成相关法尼醇X受体(farnesoid X receptor,FXR)-固醇调节元件结合蛋白-1c(sterol regulatory element-bindingprotein-1c,Srebp1c)-脂肪酸合成酶(fatty acid synthase,FAS)通路及外源性脂肪酸摄入相关的白细胞分化抗原36(cluster of differentiation 36,CD36)为切入点,探讨祛痰活血方抗非酒精性脂肪性肝病(non-alcoholic fatty liver disease,NAFLD)的分子机制。方法 雄性C57BL/6J小鼠,随机分为对照组、模型组、祛痰活血方组和易善复组,每组各10只。模型组、祛痰活血方组和易善复组给予高脂饲料喂养,4周后祛痰活血方组和易善复组开始给药干预,给药8周后取各组小鼠血清用于生化检测;肝组织用于病理、肝脏总胆固醇(cholesterol,TC)、甘油三酯(triglyceride,TG)含量及FXR、Srebp1c、FAS、CD36基因及蛋白表达的检测。结果 与对照组比较,模型组小鼠体质量、肝质量明显增加(P<0.05);肝组织病理结果及肝脏TC、TG含量的升高(P<0.01)均提示明显脂肪变性;肝组织FXR、Srebp1c的m RNA表达水平,以及CD36的m RNA和蛋白表达均明显上升(P<0.01),FAS蛋白表达下降(P<0.05);与模型组比较,祛痰活血组小鼠体质量、肝质量均明显降低(P<0.01);肝组织脂肪变性明显减轻;肝组织中FXR m RNA表达明显升高(P<0.01),Srebp1c、FAS、CD36的m RNA及蛋白表达均明显降低(P<0.05)。结论 外源性脂肪酸摄入增加可能是高脂引起的NAFLD的主要成因,祛痰活血方既抑制外源性脂肪酸摄入,亦减少内源性脂肪酸合成,双向调节改善NAFLD。

说“象”:中华民族舞蹈原始发生蠡测续说(二)

“象”是中华民族舞蹈原始发生中的一种文化存在。《象舞》是周代一个比较重要的祭祀舞蹈。作为周公纪功乐舞的《象》又称《象箾》,《象》的“以箾为仪”指向《易》的“象也者像也”。汉代宫廷中有一种专职艺人称为“象人”,“象人”的“蒙假面”与“方相氏”的“相人”之意均与丧葬事宜相关。荀子《非相》的义理积淀于“偶人”的形制和“面具”的图式之中;张衡《西京赋》的“舞像”更指向整体的“舞者”——其中的汉之“戏象”一词,正是从“戏倡舞像”中点化而来,而“戏倡舞像”本自“尸礼废而像事兴”。由“象人”与偶、与俑、与傀儡的关联一直联系到“傀儡戏”,显然已远离周公的纪功乐舞《象》,也无关乎《荀子·儒教》所言,“戏象”之说显然是从“舞象”一词演变而来的。

论方学渐对王学的修正及其对桐城方氏家族文化的影响

晚明王学末流将王阳明“心体无善恶之说”导向两个路径:一是与释氏空观合流,使士人摆落世事,消解入世热情;二是很多士人将该学说,作为纵情肆欲、不讲是非道德之借口。方学渐学术思想总体是心学立场,但他又是王学修正派。他坚持心体至善说,反对王阳明、王畿“无善无恶心之体”说,其目的是为了纯正社会风俗,维护儒家礼教。他不轻言本体,主张上达即在下学之中,推崇庸德庸言之践履,是王门中的务实派。他主张以道问学辅助尊德性,对王学末流之反知主义是一个纠正。这些思想特点,对桐城方氏族人推尊忠孝节义、重视知识教育都有很大影响,从而形成一种家族风气,成为后世方氏族人立身和写作的灵魂。

“语录不可阑入古文”说的生成及现代省思

唐宋以降,禅宗语录和儒家语录大行于世,流风所及,许多文士在古文写作中也自觉或不自觉地效仿语录形式,或者掺入语录中的常见用语。这种做法相当普遍,但也有不少反对的声音。迄至清代前中期,“语录不可阑入古文”成为一种集体认同。在此过程中,方苞个人思想和文学实践所起的推动作用不容忽视。这一古文观念对于端正学风、维护古文体性、推动清代古文发展起到了积极作用,但它有绝对化的倾向,因而又有其局限性。古文发展的事实证明,在合适的场合适当借鉴、采用语录形式,不仅不会伤害古文之体,相反会给古文的表达带来别样的趣味和效果。
