Objective:Clinical part:Meta-analysis was used to systematically evaluate the clinical efficacy of traditional Chinese medicine in the treatment of diabetic erectile dysfunction(DIED),in order to objectively evaluate the effectiveness and safety of traditional Chinese medicine in the treatment of DIED.In the first part of the experiment,the Sprague Dawley(SD)rat model of Diabetes-induced dysfunction(DIED)was established,and the serum of each group was determined by intervention of high-medium-medium and low-dose groups of Chinese medicine.Sex hormones,blood glucose,sexual function and the expression of related factors in PI3K/Akt and RhoA/Rho signaling pathways in the corpus cavernosum tissues were explored from the perspectives of whole,tissue and molecular levels to explore the mechanism of DIED in the treatment of DIED.Part 2:By establishing a SD rat model of diabetic erectile dysfunction(DIED),the intervention of Shijingtongluo Recipe and its decomposed formulas was performed to determine serum sex hormones,blood glucose,sexual function and corpus cavernosum tissues of each group of rats.The changes of the expression of related factors in PI3K/Akt and RhoA/Rho signaling pathways were discussed at the different levels of the whole,tissues and molecules to explore the compatibility of Filling Tongluo Recipe in the treatment of DIED.Methods:Clinical section:by search including PubMed,Cochrane Library,AMED,EMbase,WorldSciNet,Nature,Science online and China Journal Full-text Database(CNKI),China Biomedical Literature CD-ROM Database(CBM),China Resources Database.Two evaluators independently extracted data and performed methodological quality assessment.Data analysis was performed using RevMan 5.3 software.Part of the experiment:1.90 SD male rats were randomly divided into normal group,DIED model group,positive drug control group,Chinese medicine high-dose group,Chinese medicine middle-dose group,and traditional Chinese medicine low-dose group,with 15 rats in each group.Fifteen of the normal group were not administered,and the remaining five groups of 75 rats were modeled using streptozotocin(STZ).After the model was successful,the normal group was given an equal amount of normal saline.The model group was given a high-fat,high-sugar diet.The positive drug control group was given tadalafil 0.2 mg/kg twice a week.The other groups were given different doses of traditional Chinese medicine for filling Jingjingtong.The above groups of interventions lasted for 4 weeks.After 4 weeks of administration,serum levels of sex hormones were determined by enzyme-linked immunosorbent assay.Western blot and PCR were used to detect nitric oxide synthase(eNOS),threonine protein kinase Akt,RhoA,Expression of Rho kinase and phosphodiesterase type 5(PDE5)-associated protein and mRNA.The changes of serum Ca2+levels in each group were detected by flow cytometry.3 Experimental data were analyzed using SPSS 24.0 statistical software.The second part of the experiment:1.90 SD male rats were randomly divided into normal group,DIED model group,positive drug control group,filling group,Tongluo group and Rongjingtongluo group.Fifteen of the normal group were not administered,and the remaining five groups of 75 rats were modeled using streptozotocin(STZ).After the model was successful,the normal group was given an equal amount of normal saline.The model group was given a high-fat,high-sugar diet.The positive drug control group was given tadalafil 0.2 mg/kg twice a week.The remaining groups were given the corresponding disassembled for treatment.The above groups of interventions lasted for 4 weeks.After 4 weeks of administration,serum levels of sex hormones were determined by enzyme-linked immunosorbent assay.Western blot and PCR were used to detect nitric oxide synthase(eNOS),threonine protein kinase Akt,RhoA,Expression of Rho kinase and phosphodiesterase type 5(PDE5)-associated protein and mRNA.The changes of serum Ca2+levels in each group were detected by flow cytometry.3.Experimental data were analyzed using SPSS 24.0 statistical software.Results:Clinical section:A total of 8 articles,including 585 patients,were included.The use of traditional Chinese medicine alone or in combination with conventional western medicine can significantly improve the IIEF-5 score in DIED patients,and the efficacy of traditional Chinese medicine in improving erectile function in DIED patients is better than that in the control group[95%CI(4.21,5.07),P<0.00001]The total efficacy of traditional Chinese medicine alone or in combination with conventional western medicine for DIED was better than that of the control group[OR=4.83,95%CI(2.81,8.29),P<0.00001].In the experimental part one:1.After 4 weeks of treatment,the sexual function indexes of each group were detected,and the number of snoring,the first crawling time,the number of riding times and the number of insertions were observed.The difference

alone or in combination with conventional western medicine can better improve the erectile function of DIED patients.Among them,in the process of DIED treatment,traditional Chinese medicine is one of the most frequently used traditional Chinese medicines for filling and refining Tongluo,tonifying kidney and filling essence,and activating blood circulation and collaterals as the basic treatment rule has been widely used in the clinical practice of DIED,and no serious adverse reactions have been reported.An effective and safe method for treating DIED has high application value and promotion significance.Experimental part 1:1.Filling Jingjingtong traditional Chinese medicine can improve the erectile function of DIED rats,and the effect of filling high dose group of traditional Chinese medicine is more significant.2.The possible mechanism of filling Jingjingtongzhong Chinese medicine to improve erectile dysfunction in DIED rats is to up-regulate the expression of Aktl in PI3K/Akt signaling pathway and down-regulate the expression of RhoA,ROCK1 and ROCK2 proteins in RhoA/Rho pathway,leading to eNOS phosphorylation.It can reduce the Ca2+level and the expression of PDE-5 protein,promote the relaxation of cavernous smooth muscle and reduce the contraction of cavernous smooth muscle,and achieve the purpose of treating diabetic ED.3.Key molecules targeting PI3K/Akt and RhoA/Rho signaling pathways can provide an important basis for PI3K/Akt and RhoA/Rho to become new targets for DIED treatment,and provide an alternative new method for DIED treatment.Experimental part 2:1.Filling the traditional Chinese medicine and its decomposed formula can improve the erectile function of DIED rats.The role of the filling and meridian group in the sexual function and serum sex hormones of rats is better than that of the simple filling group or pass.The group,Chinese medicine treatment of diabetic erectile dysfunction,should adhere to the principle of comprehensive treatment of filling and clearing the network.2.The possible mechanism of filling Jingjingtongzhong Chinese medicine to improve erectile dysfunction in DIED rats is to up-regulate the expression of Aktl in PI3K/Akt signaling pathway and down-regulate the expression of RhoA,ROCK1 and ROCK2 proteins in RhoA/Rho pathway,leading to eNOS phosphorylation.It can reduce the Ca2+level and the expression of PDE-5 protein,promote the relaxation of cavernous smooth muscle and reduce the contraction of cavernous smooth muscle,and achieve the purpose of treating diabetic ED.3.Filling the essence and compatibility of the whole party is superior to other combinations,reflecting the overall concept of TCM treatment.Filling the essence of traditional Chinese medicine will have different sexual tastes,and the drugs with different effects will be combined with each other to reflect the synergistic effect of the compatibility of the prescriptions,thus forming the best compatibility form,confirming...
