[Exploration of erectile dysfunction syndrome and syndrome differentiation based on latent structure].

OBJECTIVE: In order to exploring Erectile Dysfunction(ED) syndrome and syndrome differentiation based on latent structure to provide objective evidence to support Traditional Chinese Medicine(TCM) dialectic. METHODS: Cases and clinical experience in the treatment of erectile dysfunction in Chinese medicine in CNKI, Wanfang Database, cqVIP Database, were searched. Time from the database construction to January, 2023. Extraction and specification of symptom data with reference to national standards. Lantern 5.0 software was used to make the latent structure of the data based on LTM-EAST method. Latent probability, conditional probability, information coverage, mutual information and other data were combined to manually interpret the model and perform clustering analysis on the latent classes to analyze the symptomatic features and clinical evidence of erectile dysfunction and establish the rules of identification. RESULT: A total of 361 cases of erectile dysfunction were included, 21 latent variables were constructed, 9 comprehensive clustering models and 13 discriminative rules were established. The pathological factors of the obtained erectile dysfunction are dampness, heat, yin deficiency, blood stasis, spleen deficiency, kidney deficiency, liver depression, and qi stagnation. The certificate types are stasis of blood, liver qi stagnation, damp-heat entrapment (dampness is heavy, heat is heavy, damp-heat is heavy), yin deficiency (yin deficiency with heat, kidney yin deficiency), vital fire failure, qi deficiency (qi deficiency with heat, kidney qi deficiency), heart and spleen deficiency, panic injury to kidney, spleen and kidney deficiency. CONCLUSION: The common types of erectile dysfunction obtained are generally consistent with existing guidelines, but more subcategories exist in the certificate type. The presence of symptoms that cannot be well matched in some of the certificate types is presumed to be due to the complex pathogenesis of erectile dysfunction common compound evidence, many evidence models are seen in the main symptoms of liver qi stagnation evidence pulse strings, suggesting that clinical treatment should pay attention to the regulation of emotional and moral, to ease the patient's emotions. The corresponding dialectical rules can quantify the dialectical criteria and provide an objective basis for non-TCM professionals to clinically determine the TCM evidence type of patients.

[Luobufukebiri Pills improve semen quality and seminal plasma-related biochemical indexes in patients with asthenospermia].

OBJECTIVE: To investigate the clinical effect of Luobufukebiri Pills (LP) on asthenospermia and its action mechanism. METHODS: A total of 206 patients with asthenospermia in Henan Provincial Hospital of Traditional Chinese Medicine from March 2018 to December 2018 were randomly assigned to receive oral LP (the experimental group, n = 103) bid 10 pills each time or vitamin E soft capsules (the control group, n = 103) bid 100 mg each time for a course of 12 weeks. We compared the semen volume, sperm concentration, sperm motility, levels of α-glucosidase (α-Glu), fructose (Fru), malondialdehyde (MDA) and superoxide dismutase (SOD) in the seminal plasma, and the number of pregnancies between the two groups of patients before and after treatment. RESULTS: All the patients finished the experiment except 1 in the control group due to personal reasons. After 12 weeks of medication, the patients in the experimental group showed significant increases over the baseline in sperm concentration (ï¼»36.27 ± 11.05ï¼½ vs ï¼»25.96 ± 8.63ï¼½ ×106/ml, P < 0.05), grade a sperm (ï¼»16.92 ± 5.72ï¼½% vs ï¼»9.34 ± 3.18ï¼½%, P < 0.05), grade a+b sperm (ï¼»36.08 ± 6.84ï¼½% vs ï¼»19.88 ± 4.65ï¼½%, P < 0.05), total sperm motility (ï¼»50.37 ± 10.38ï¼½% vs ï¼»24.62 ± 6.12ï¼½%, P < 0.05), and the levels of α-Glu (ï¼»46.94 ± 9.16ï¼½ vs ï¼»32.25 ± 8.30ï¼½ U/ml, P < 0.05), Fru (ï¼»28.08 ± 5.72ï¼½ vs ï¼»16.38 ± 4.62ï¼½ µmol/ml, P < 0.05) and SOD (ï¼»182.28 ± 18.44ï¼½ vs ï¼»100.37 ± 10.22ï¼½ U/ml, P < 0.05), but a decrease in the content of seminal plasma MDA (ï¼»10.37 ± 2.93ï¼½ vs ï¼»15.62 ± 4.68ï¼½ nmol/ml, P < 0.05). Increases were also observed in the control group over the baseline in grade a sperm (ï¼»12.40 ± 6.33ï¼½% vs ï¼»9.26 ± 2.94ï¼½%, P < 0.05), grade a+b sperm (ï¼»25.42 ± 5.24ï¼½% vs ï¼»19.43 ± 4.17ï¼½%, P < 0.05), total sperm motility (ï¼»40.22 ± 9.72ï¼½% vs ï¼»23.99 ± 5.77ï¼½%, P < 0.05), and levels of α-Glu (ï¼»40.31 ± 8.22ï¼½ vs ï¼»31.06 ± 7.51ï¼½ U/ml, P < 0.05) and SOD (ï¼»139.71 ± 14.08ï¼½ vs ï¼»102.11 ± 9.24ï¼½ U/ml, P < 0.05), but a decrease in the content of seminal plasma MDA (ï¼»12.72 ± 3.11ï¼½ vs ï¼»15.62 ± 4.68ï¼½ nmol/ml, P < 0.05). The total clinical effectiveness rate was remarkably higher in the experimental than in the control group (87.38% vs 58.82%, P < 0.05). CONCLUSIONS: Luobufukebiri Pills are safe and effective for the treatment of asthenospermia, which may be attributed to their ability of improving oxidative stress damage.

Characteristics of Chinese Medicine Education Under British Education System in New Zealand.

With the globalisation of Chinese medicine (CM), the local CM education institutions were established in many other countries outside of China. These CM education institutions have formed a new mode in CM education after integrating with local culture, law and national conditions. This article takes New Zealand CM education institutions as an example to discuss the characteristics of CM education under the British education system, aiming to provide ideas on CM education in China and other countries.

[Protective effect of Yishen Tongluo Recipe against benzo(a)pyrene-induced sperm DNA methylation changes in male rats].

OBJECTIVE: To explore the protective effect of Yishen Tongluo Recipe (YTR) against aberrant sperm DNA methylation in male rats exposed to benzo(a)pyrene (BaP). METHODS: Thirty male SD rats of the SPF grade were randomly divided into three groups of equal number: solvent control, BaP exposure and YTR intervention. The animals of the solvent control group were injected intraperitoneally with 0.5% DMSO while those of the other two groups with BaP at 0.1 mg/kg/d, all for 60 days, and at 31 days of BaP exposure, those of the YTR group were treated intragastrically with YTR for 30 days. Then, the left epididymides were harvested from all the rats and sperm suspensions collected and centrifuged for extraction of sperm DNA. The methylated DNA immunoprecipitation sequencing (MeDIP-seq) technique was used to detect the whole-genome DNA methylation in different groups. RESULTS: Exposure to BaP induced the up-regulation of 828 genes encoding mRNA in the sperm DNA, while YTR intervention produced a significant protective effect on the transforming growth factor ß3 (TGF-ß3), cystic fibrosis transmembrane conductance regulator (CFTR) and recombination activating gene 1 (RAG1), and down-regulated the expressions of 3 227 genes. BaP exposure also caused the up-regulation of 783 genes encoding lncRNA in the sperm DNA, and YTR treatment exhibited an evident protective effect on 62 of the up-regulated genes, induced the down-regulation of 3 378 genes, and showed a protective effect on 56 of the down-regulated genes. CONCLUSIONS: YTR has a protective effect against aberrant sperm DNA methylation in male rats exposed to BaP, which may be associated with lncRNA.

[Efficacy observation on chronic pelvic pain syndrome of damp-heat stagnation pattern treated with acupoint catgut embedding therapy].

OBJECTIVE: To compare the efficacy difference in the treatment of chronic pelvic pain syndrome of Sev-damp-heat stagnation pattern between acupoint catgut embedding therapy and western medication. METHODS: enty cases were randomized into a catgut embedding group (40 cases) and a western medication group (30 cases) at the ratio of 4 : 3. In the catgut embedding group, the catgut embedding therapy was applied to Sanyinjiao (SP 6), Quchi (LI 11), Huiyin (CV 1), Zusanli (ST 36), Zhongji (CV 3), Shenshu (BL 23), etc. The treatment was given once every two weeks, the treatment for 4 weeks was as one session and totally 2 sessions were required. In the western medication group, tamsulosin hydrochloride capsules 0. 2 mg, oral administration, once a day, and Indometacin sustained release tablets, 75 mg, once a day, 3 tablets each time were prescribed. The symptom score of TCM, score of NIH Chronic Prostatitis Symptom Index (NIH-CPSI), lecithin body number in prostatic fluid, (SAS) score of Self-Rating Anxiety Scale and score of Self-Rating Depression Scale (SDS) were compared before and after treatment in the patients of the two groups. The efficacy was evaluated in the two groups. RESULTS: (1)The total effective rate was 91. 9% (34/37) in the catgutembedding group and was 86. 2% (25/29) in the western medication group. The efficacy in the catgutembedding group was better than that in the western medication group (P<0. 05). (2) The symptom score of TCM was all reduced significantly after treatment in the two groups (both P<0.01), and the result in the catgut embedding group was superior to the western medication group (6.42 +/-2. 81 vs 10. 99+/-3. 11 ,P<0. 01). (3) Lecithin body number was increased apparently in the two groups after treatment (both P<0.01), and the result in the catgut-embedding group was superior to the western medicine group (33.56+/-5.88 vs 29. 78+/-7. 06,P<0. 05). (4) Total score of NIH-CPSI, score of pain, score of SAS and score of SDS were all improved apparently after treatment in the two groups (all P<0. 01), and the results in the catgut embedding group were superior to the western medication group (P<0. 01, P<0. 05). CONCLUSION: The acupoint catgut embedding therapy achieves the superior efficacy on chronic pelvic pain syndrome of damp-heat stagnation pattern as compared with conventional western medicine. This therapy relieves clinical symptoms, improves the states of anxiety and depression and increases lecithin body number obviously.

[Common TCM syndrome pattern of chronic pelvic pain syndrome relates to plasma substance p and beta endorphin].

OBJECTIVE: To investigate the relationship of the common Traditional Chinese Medicine (TCM) syndrome pattern of chronic pelvic pain syndrome (CPPS) with the contents of substance p and beta endorphin in the plasma, and provide reference data for the clinical diagnosis, differentiation and treatment of CPPS by TCM. METHODS: We observed 98 cases of CPPS, which were classified into a lower-part damp-heat invasion group (group A, n = 32), a blood stasis-induced collateral obstruction group (group B, n = 34), and a damp-heat stagnation group (group C, n = 32) according to the TCM syndrome differentiation. Another 35 normal healthy young men were enrolled as controls. We measured the contents of substance p and beta endorphin in the plasma by immunoradiometry and ELISA, and analyzed their relationship with the TCM syndrome pattern. RESULTS: The contents of plasma substance p were significantly higher in groups A ([1135.76 +/- 166.45] pg/ml), B ([1 337.84 +/- 170.81] pg/ml), and C ([1 210.01 +/- 162.27] pg/ml) than in the control ([574.99 +/- 113.09] pg/ml) (all P < 0.01), while the contents of plasma beta endorphin in groups A ([212.70 +/- 29.49] pg/ml), B ([157.99 +/- 24.01] pg/ml), and C ([180.81 +/- 20.20] pg/ml) were remarkably lower than that in the control ([274.73 +/- 27.64] pg/ml) (all P < 0.01). CONCLUSION: In the plasma of CPPS patients, the content of substance p is significantly elevated and that of beta endorphin markedly reduced, which suggests that they may be involved in the inflammatory reaction of CPPS. The levels of plasma substance p and beta endorphin can be used as valuable reference for the TCM classification of chronic prostatitis.
