[Professor MA Kun treats infertility caused by uterine dysplasia with kidney deficiency and blood stasis].

Uterine dysplasia is a common cause of infertility. Traditional Chinese medicine has unique advantages in the treatment of this disease. This paper introduces a case of infertility caused by uterine dysplasia treated by Professor MA Kun who adopted the therapy of tonifying kidney and activating blood, aiming to summarize the theoretical foundation and formula principles of Professor MA Kun in the clinical treatment of this disease. The kidney stores essence and governs reproduction. Kidney deficiency is the root cause of infertility. The deficiencies in kidney Qi, Yin, and Yang can result in blood stasis to obstruct the uterus, leading to insufficient source for essence and aggravating kidney deficiency. Kidney deficiency and blood stasis affect each other and form a vicious cycle, resulting in uterine dysplasia due to insufficient nutrition and difficult pregnancy. Therefore, Professor MA Kun believes that kidney deficiency and blood stasis is the key pathogenesis of infertility caused by uterine dysplasia and proposes the treatment principle of tonifying kidney and activating blood. Sufficient essence and Qi in the kidney can resolve stasis and generate blood, thus harmonizing Yin and Yang, which can reach thoroughfare and conception vessels to nourish the uterus and recover the normal physiological function of the uterus. In that case, normal pregnancy is possible. Professor MA Kun attaches importance to the therapeutic principle of supplementing Qi and nourishing blood. In addition, she advocates conforming to changes in the menstrual cycle to promote the development of the uterus and the implantation of fertilized eggs. She also integrates traditional Chinese medicine and western medicine to treat both symptoms and root causes. Professor MA Kun's experience has demonstrated definite clinical effect on this disease and can be taken as a reference.

Bushen Culuan Decoction Ameliorates Premature Ovarian Insufficiency by Acting on the Nrf2/ARE Signaling Pathway to Alleviate Oxidative Stress.

Premature ovarian insufficiency (POI) can result in lower fertility and shorten the female reproductive span. Bushen-Culuan Decoction (BCD) is a traditional Chinese medication utilized for treating POI for many years. We previously observed that BCD protects against further deterioration of the ovarian reserve of POI patients, however, the underlying mechanism has not been well studied. Our investigation seeks to evaluate the effect of BCD on POI induced by Tripterygium wilfordii polyglycosidium (TWP) and the likely mechanistic pathways, which we hypothesize may involve the Nrf2/ARE pathway. The body weights, estrous cycle, serum hormone levels, histological follicular analysis and quantification, levels of oxidative stress biomarkers in the ovarian tissue of POI mice models were evaluated. Western blotting and RT-PCR enabled quantification of the components of the Nrf2/ARE pathway. Our results showed that BCD restored hormonal profiles and estrous cycles of POI mice similar to those observed in healthy controls. BCD reduced the numbers of atretic follicles while increasing the number of primordial follicles. BCD facilitated lower 8-OHdG and MDA levels while increasing levels of key antioxidant enzymes including GSH-Px, CAT, and SOD. Furthermore, TWP increased Bach 1, Nrf2, and Keap 1 expressions at the translational level, while decreased that of HO-1. BCD treatment also promoted nuclear translocation rates of Bach 1 and Nrf2, suppressed Keap 1 protein expression, as well as raised HO-1 protein expression. Taken together, BCD likely augments ovarian reserve by activating the Nrf2/ARE signaling pathway, which stimulated higher levels of antioxidants and suppressed oxidative stress. BCD may be an important therapeutic compound in POI.

Efficacy of Bushen Culuan decoction on ovarian follicle and follicular granulosa cells in mice with premature ovarian insufficiency induced by tripterygium wilfordii polyglycoside.

OBJECTIVE: To investigate the protective efficacy of Bushen Culuan decoction (BCD) on ovarian follicle and follicular granulosa cells in mice with premature ovarian insufficiency (POI) induced by tripterygium wilfordii polyglycoside, and to study the potential mechanism underlying the action. METHODS: Eighty female Balb/c mice were randomly divided into 4 groups (n = 20 each): blank group, model group, Bushen Culuan decoction intervening group (BCD group) and estradiol valerate intervening group (EV group). In the first 14 model establishing d, mice in model group, BCD group and EV group were under Tripterygium wilfordii polyglycoside (TWP) gavage to establish POI models. In the 14-day therapeutic stage, mice in BCD group were taken BCD 18.35 mg·kg-1d-1, mice in EV group were taken EV solution 0.15 mg·kg-1d-1, while mice in blank group and model group were taken normal saline. When the mice accomplished therapy, whole blood was collected for serum hormone including follicle stimulating hormone (FSH), luteal hormone (LH), estradiol (E2), antimullerian hormone (AMH) levels and vascular endothelial growth factor (VEGF), bone morphogenetic protein-7 (BMP-7) measurement. Ovarian tissues were harvested for morphologic observation, follicle counting, ovarian follicular graulosa cell apoptosis test and testing BMP-7 and caspase-3 expressions. RESULTS: The body weights of the mice kept growing stably in the process expect in TWP intervening stage. Compared with model group, BCD group had significantly higher ovarian index, serum E2, AMH, VEGF, BMP-7 levels and significantly lower FSH level (P < 0.05). Meanwhile the VEGF level in BCD group was higher than in EV group (P < 0.05). Compared with model group, the histopathological damage and GCs apoptosis were mitigated; developing follicle counting, BMP-7 expression were up-regulated, and caspase-3 expression was downregulated in BCD groups (P < 0.05). CONCLUSION: BCD treatment could attenuate pathological process in POI ovaries, suppress GC apoptosis, probably through promoting BMP-7 expression and following inhibiting caspase-3 activation.

[Effect of therapies for kidney-tonifying and blood-activating in treatment of anovulatory infertility in eugenics].

In the context of the new era, paying attention to maternal and child health and advocating prenatal and postnatal care can effectively improve the quality of the birth population. Traditional Chinese medicine has a long history of prenatal and postnatal healthcare with rich content, which is the theoretical basis of modern related services. With the social development and the improvement of people's awareness of prenatal and postnatal healthcare, people have gradually shifted the focus of prenatal and postnatal healthcare to the peri-pregnancy stage at present, namely that couples of childbearing age are guided to prepare for pregnancy under the premise of solving their basic diseases. Infertility is a common and refractory disease for women of childbearing age. Ovulation disorder is one of its common pathological mechanisms. Traditional Chinese medicine believes that kidney deficiency is the main cause and pa-thogenesis of anovulation infertility and blood stasis is an important factor throughout the disease course. In clinical practice, therapies for invigorating kidney and activating blood are safe and reliable to treat anovulatory infertility mainly by adjusting the hypothalamus-pituitary-ovarian axis, improving ovarian function, uterine environment and gamete quality and increasing endometrial volume. Under the guidance of the thought of prenatal and postnatal healthcare, the authors tried to explore the effect of therapies for kidney-tonifying and blood-activating in the treatment of anovulatory infertility in eugenics, with the purpose of providing ideas and basis for subsequent relevant clinical studies and contributing to prenatal and postnatal healthcare services.

[Study on mechanism of Bushen Culuan Formula in treatment of polycystic ovary syndrome based on network pharmacology and molecular docking].

This study used network pharmacology and molecular docking to study the mechanism of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS). The active ingredients and potential drug targets of Bushen Cu-luan Decoction were obtained by searching the Traditional Chinese Medicine System Pharmacology(TCMSP) database, and the targets of PCOS by searching GeneCards. After the drug targets and disease targets were corrected by Uniprot, the intersection genes were obtained. STRING database and Cytoscape 3.7.2 were used for protein-protein interaction(PPI) analysis of the intersection genes. The ClueGO plug-in of Cytoscape 3.7.2 was employed to perform gene ontology(GO) enrichment and KEGG pathway enrichment for the intersection genes. Finally, molecular docking of the key active ingredients with the targets of Bushen Culuan Formula was performed using AutoDockVina and MGLtools. A total of 136 active ingredients and 314 drug targets of the decoction were obtained from TCMSP, and 136 disease targets from GeneCards. Finally, 49 drug-disease intersection genes were obtained. GO enrichment found that the genes were mainly involved in the regulation of muscle cell apoptosis, positive regulation of small molecule metabolism, core promoter binding, RNA polymerase Ⅱ regulation of pri-miRNA transcription, negative regulation of transmembrane transport and other biological functions. The enriched KEGG pathways mainly included MAPK, PI3 K-Akt, p53, and HIF-1 signaling pathways. The results of molecular docking showed that quercetin and PTGS2 can bind stably and interact through amino acid residues THR206, TRP387, ASN382, etc. This study preliminarily reveals the multi-component, multi-target, and multi-pathway mechanism of Bushen Culuan Formula in the treatment of PCOS-related infertility, which provides a basis for further research.

Dingkun Pill replenishes diminished ovarian reserve through the PI3K/AKT/mTOR signaling pathway in TWP-induced mice.

ETHNOPHARMACOLOGICAL RELEVANCE: Diminished ovarian reserve (DOR) can lead to poor fertility and shorten the reproductive lifespan of females. The Dingkun Pill (DKP), a traditional Chinese-patented medication, has been an integral part of traditional Chinese medicinal treatment for the management of gynecological diseases for centuries. Relevant clinical studies have shown that DKP is able to protect against DOR, however, its mechanism of action is not yet fully elucidated. STUDY GOALS: This study was conducted with the aim of exploring the impact of tripterygium wilfordii polyglycosidium (TWP) on the PI3K/AKT/mTOR pathway in the context of the pathophysiology of DOR and the mechanism of action of DKP. MATERIALS AND METHODS: Eighty female balb/c mice with regular estrous cycles were assigned to Blank, Model, DKP and hormone replacement therapy (HRT) groups in a random manner. With the exception of the Blank group, mice in the other groups were exposed to 40 mg/kg/d TWP suspension for 30 days to DOR induction. Following this, either DKP or hormones were orally administrated to determine their effect on disease progression. During the experiment, changes in body weight and the estrous cycles of the mice were observed. Post treatment, serum sample anti-mullerian hormone (AMH), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels were quantified using enzyme-linked immunosorbent assay (ELISA). The mice were then sacrificed in order to harvest their ovaries for hematoxylin and eosin (HE) staining. This process allowed for the assessment of ovarian morphology and follicular quantification. Apoptotic ovarian cells of the ovary were assessed using TUNEL technique, while Caspase-3 and Cytochrome C (Cyt C) expressions of the ovary were examined through immunohistochemistry (IHC). Western blotting analysis was used to quantify levels of Bax, Bcl-2, Caspase-3, Cyt C, mTOR, P-mTOR, AKT, P-AKT, P-PI3K and PI3K proteins, while mRNA levels of Bax, Bcl-2, PI3K, AKT and mTOR were measured in ovarian tissue using RT-PCR. RESULTS: The findings revealed that DKP was able to improve levels of serum hormones and promote the recovery of the estrous cycle. DKP augmented the total amount of primordial follicles while reducing the number of follicles that were atretic follicles. The apoptosis index of growing follicles and Bax, Cyt C and Caspase-3 expressions decreased, while the Bcl-2: Bax ratio increased. DKP suppressed levels of phosphorylation and the mRNA expressions of mTOR, AKT and PI3K. CONCLUSIONS: It was demonstrated that DKP was able to increase ovarian reserves through inhibition of the PI3K/AKT/mTOR signaling pathway, which lead to the suppression of primordial follicle activity and a reduction in levels of apoptosis of early growing follicles. This highlights its potentially beneficial role for the treatment of DOR.

[Establishment of premature ovarian insufficiency kidney deficiency and blood stasis pattern mouse model with Tripterygium wilfordii polyglycoside for Bushen Culuan Decoction therapy].

To establish a mouse model of premature ovarian insufficiency( POI) with kidney deficiency and blood stasis pattern by Tripterygium wilfordii polyglycoside( TWP) gavage,and to evaluate the ovarian function and fertility of the model,in order to find Bushen Culuan Decoction therapeutic mechanism. 60 SPF level Blab/c female mice with normal estrous cycle were randomly divided into 6 groups of 10 each: blank group 1( BG1),blank group 2( BG2),blank fertility group( BFG),model group( MG),model recovery group( MRG) and model fertility group( MFG). The mice in three model groups were treated by gastric gavage with TWP suspension 40 mg·kg-1 twice a day for 14 days,while the mice in three blank groups were treated by gastric gavage with same volume normal saline for 14 days. The mice in BG1 and MG were sacrificed and dissected on day 15. The mice in BG2,BFG,MRG and MFG were returned normal feeding from day 15 and were sacrificed and dissected on day 29. The mice in BFG and MFG were cohabited with male mice with a ratio of 2 ∶1( female ∶male) from day 15. The general situation and estrous cycles of all mice were observed every day. Serum sex hormone levels,ovarian index,uterine index,ovarian morphology,follicle count,ovarian VEGF and ES index were observed within the mice in BG1,BG2,MG and MRG. Pregnancy rate,litter size,survival number of newborn mice and male-female proportion were reported within the mice in BFG and MFG. In model establishing stage,the body weight of mice significantly decreased( P <0. 05) in MG and MFG. Compared with BG1,the mice in model group had irregular estrous cycle,decreased ovarian and uterine indexes,less primordial and developing follicles,more atretic follicles,increased VEGF expression and decreased ES expression( P <0. 05). Compared with blank group 2,the mice in model recovery group had irregular estrous cycle,increased FSH level,decreased ovarian indexes,less primordial and developing follicles,more atretic follicles,increased VEGF expression( P<0. 05). Compared with blank fertility group,the mice in model fertility group had smaller litter size and newborn mice survival count( P<0. 05). Gastric gavage with TWP 40 mg·kg-1 twice a day for 14 days is a feasible way to establish a POI kidney deficiency and blood stasis pattern mouse model. The mice ovarian functions didn't recovery on day 14 after stopping TWP intervening,which could suggest the effectiveness of subsequent therapeutic intervention.

[Systematic review and Meta-analysis of effect of Yinzhihuang Oral Liquid in treatment of neonatal jaundice].

To systematically review effectiveness and safety of Yinzhihuang Oral Liquid in the treatment of neonatal jaundice. A systematic retrieval was performed throughout China National Knowledge Infrastructure( CNKI),Wan Fang,VIP,Sino Med and PubMed,Medline,Cochrane Library databases from the establishment to April 2019. Randomized controlled trials of Yinzhihuang Oral Liquid in treatment of neonatal hyperbilirubinemia were retrieved. Clinical studies in line with the inclusion criteria were involved for data extraction,and the quality of the included literatures was evaluated by the risk bias assessment tool in the Cochrane review manual. Finally,Meta-analysis was performed by Rev Man 5.3 software. A total of 30 studies were involved,involving 3 923 child patients,including1 940 in observation group and 1 983 in control group. According to the results of Meta-analysis,the total effective rate( RR = 1. 22,95%CI[1. 18,1. 26],P<0. 000 01),level of TBi L after treatment( MD =-38. 78,95%CI[-48. 38,-29. 18],P<0. 000 01),time to jaundice resolution( MD =-1. 76,95% CI[-2. 10,-1. 41],P < 0. 000 01) and daily average decrease value of bilirubin( MD =11. 67,95%CI[8. 89,14. 45],P<0. 000 01) of observation group were significantly better than those of control group,with statistically significant differences. Adverse reactions were reported in nine studies,mainly including diarrhea,vomiting,fever,rash and other symptoms,which did not affect the treatment effect. The effectiveness of Yinzhihuang Oral Liquid combined with conventional therapy in treating neonatal jaundice was better than conventional therapy alone,with little adverse reactions. However,most of literatures included had a low research quality,which impacted the reliability of the conclusion. Therefore,it is suggested to conduct more largesample-size,multicenter,scientifically designed,strictly implemented high-quality randomized controlled trials in the future,in order to study the efficacy and safety of Yinzhihuang Oral Liquid in the treatment of neonatal jaundice.
