Discussion on Current National Standards for Traditional Chinese Medicine Dispensing Granules / 中国实验方剂学杂志

Strengthening the standard formulation and quality management of traditional Chinese medicine（TCM） dispensing granules is an important part of the strategic planning for the development of TCM in China. In order to examine the clinical application and overall quality control of the existing national standards for TCM dispensing granules， this study classified and summarized the varieties in the existing standards， analyzed their clinical applicability， and discussed the characteristics of the test methods for identification， content determination and specific chromatogram/fingerprint. It was found that the coverage of the existing standards was inadequate in terms of quantity， and it was even weaker in the aspects of therapeutic efficacy， herb family， processing method and preparation method of TCM dispensing granules. It was concluded that the characteristics of national standards in test methods were summarized as follows：guided by clinical application， based on the reference system， taking specific chromatogram as a breakthrough， so as to improve the overall quality control of TCM dispensing granules. It is suggested that the coverage of national standards should be subsequently expanded to meet the needs of market development. In order to enhance clinical applicability， the content of national quality standards should be increased， including increasing variety diversity to meet the needs of clinical application， raising the standard requirements to improve the clinical medication experience， and strengthening effectiveness research to highlight clinical efficacy. At the same time， the accessibility of regulatory inspection is enhanced， the rules for the management of varieties without national standards are promulgated to lay the foundation for the healthy and orderly development of TCM dispening granule industry.

Safety and efficacy of the early administration of levosimendan in patients with acute non-ST-segment elevation myocardial infarction and elevated NT-proBNP levels: An Early Management Strategy of Acute Heart Failure (EMS-AHF) / 中华内科杂志

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

In the Bazi Bushen capsules and rapamycin groups， clear structure of the red and white marrow marginal zone was observed in the spleen of mice， the area of the white marrow was increased， and the area of the red marrow was correspondingly decreased. The protein and mRNA expression of aging-related proteins p16 and p21 in the spleen was decreased （P<0.01）， the levels of serum pro-inflammatory cytokines IL-1β， IL-2， IL-12 p70， IFN-γ， and TNF-α levels were decreased， and the levels of IL-4 and IL-10 were increased （P<0.05， P<0.01） in the Bazi Bushen capsules and rapamycin groups as compared with the aging group. ConclusionBazi Bushen capsules have the effect of regulating the debilitating signs of natural aging mice， regulating the immune homeostasis and inflammation level of the body， and reducing cell aging.

Substitution mode of rare and endangered Chinese medicinal materials and research strategy of multi-component replacement / 中国中药杂志

Rare and endangered Chinese medicinal materials are the material basis for innovation and development of Chinese medicinal materials and their curative effects are remarkable. However, the resources are in shortage due to various man-made or natural factors such as rising demand, overexploitation and environmental degradation. Therefore, finding alternatives is a feasible and effective solution. This study systematically sorted out the list of rare and endangered Chinese medicinal materials, and combed relevant policies and regulations. According to existing research, the substitution model of rare and endangered Chinese medicinal materials was constructed from the theoretical level. In view of the slow search for substitutes, the failure to follow the basic theory of traditional Chinese medicine in the process of research and development, the difficulty in breaking through technologies and the incomplete guarantee of the clinical efficacy of substitutes, a multi-component replacement was proposed to replace the originals with more effective components from a wide range of sources. This study was expected to promote the study on the substitutes of rare and endangered Chinese medicinal materials to step into a new stage.

Mechanism of tonifying kidney and activating blood therapy for premature ovarian failure:a review / 中国中药杂志

Healthy birth and child development are the prerequisite for improving the overall quality of the population. However, premature ovarian failure(POF) threatens the reproductive health of women. The incidence of this disease has been on the rise, and it tends to occur in the young. The causes are complex, involving genetics, autoimmune, infectious and iatrogenic factors, but most of the causes remain unclear. At the moment, hormone replacement therapy and assisted reproductive technology are the main clinical approaches. According to traditional Chinese medicine(TCM), kidney deficiency and blood stasis are one of the major causes of POF, and TCM with the effects of tonifying kidney and activating blood has a definite effect. Through clinical trials, TCM prescriptions for POF have excellent therapeutic effect as a result of multi-target regulation and slight toxicity. In particular, they have no obvious side effects. A large number of studies have shown that the kidney-tonifying and blood-activating TCM can regulate the neuroendocrine function of hypothalamic-pituitary-ovarian axis, improve ovarian hemodynamics and microcirculation, reduce the apoptosis of granulosa cells, alleviate oxidative stress injury, and modulate immunologic balance. The mechanism is that it regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), vascular endothelial growth factor(VEGF), transforming growth factor(TGF)-β/Smads, nuclear factor E2-related factor 2(Nrf2)/antioxidant response element(ARE), and nuclear factor-kappa B(NF-κB) signaling pathways. This article summarized the pathological mechanisms of tonifying kidney and activating blood TCM in the prevention and treatment of POF and explored the biological basis of its multi-pathway and multi-target characteristics in the treatment of this disease. As a result, this study is expected to serve as a reference for the treatment of POF with the tonifying kidney and activating blood therapy.

Guiding significance of "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology (FU Qing-zhu Nyu Ke) for dealing with ovulation disorder infertility caused by hyperprolactinemia / 中国中药杂志

This paper discussed the guiding significance of "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) for dealing with ovulation disorder infertility caused by hyperprolactinemia(HPRL). FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) concentrates on the disease entities, main symptoms, pathogenesis, and syndrome differentiation, based on which the prescriptions are prescribed. This reflects the "disease-syndrome-symptom" mode, with the core lying in the "combination of disease with syndrome". The contained Discussion on Menstruation Regulation(Tiao Jing Pian) and Discussion on Getting Pregnant(Zhong Zi Pian) have important reference significance for later doctors in the diagnosis and treatment of inferti-lity, and many prescriptions are still in use due to good effects. It is believed in traditional Chinese medicine(TCM) that HPRL results from kidney deficiency and liver depression, among which kidney deficiency is the main cause. Liver depression accelerates the onset of HPRL, so the kidney-tonifying and liver-soothing herbs were mainly selected. The "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) sheds enlightenment on the diagnosis and treatment of ovulation infertility caused by HPRL, in that it is not confined to disease entity and syndrome type. The integration of "disease-syndrome-symptom" highlights the main complaint of patients and emphasizes the main pathogenesis, thus giving full play to the overall advantage of syndrome differentiation. For multiple diseases in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) such as infertility due to liver depression, infertility due to obesity, delayed menstruation, and irregular menstruation, although the typical lactation symptom of HPRL is not mentioned, the medication can still be determined according to the chief complaint, syndrome type, and symptoms and signs, making up for the defects of excessive reliance on serum biochemical indicators in modern Chinese medicine. We should learn its diagnosis and treatment thoughts of paying attention to liver, spleen, kidney, and heart, holism, and strengthening body resistance to eliminate pathogenic factors.

Study on mechanism of Bushen Culuan Formula in treatment of polycystic ovary syndrome based on network pharmacology and molecular docking / 中国中药杂志

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.

Kidney-tonifying and blood-activating in treatment of infertility due to pelvic inflammatory disease:clinical experience of Professor MA Kun / 中国中药杂志

Pelvic inflammatory disease(PID) has become one of the leading causes of female infertility, with an increasing incidence in recent years. Modern medicine believes that risk factors of PID will affect the formation of eggs and embryo implantation, especially on the encounter of gametes, fertilization, and transport of fertilized eggs to the uterine cavity. Therapies for infertility due to PID include medication, sonographic hydrotubation, surgery, and assisted reproductive technology. Professor Ma Kun believes that the disease is located in the uterus with appendages with the main pathogenesis of kidney deficiency and blood stasis. Blood stasis is the pathological basis, and kidney deficiency is the fundamental pathogenesis, which exhibits deficiency-excess in complexity. Kidney deficiency will cause blood stasis over time, while blood stasis will aggravate kidney deficiency in turn, making PID-induced infertility refractory. In clinical practice, basic therapies follow the principles of kidney-tonifying and blood-activating, removing blood stasis, dredging collaterals, and coordinating thoroughfare and conception vessels. The oral administration of Chinese medicine combined with enema, external application, and external washing displays better efficacy in improving the pelvic microenvironment and increasing the pregnancy rate and pregnancy success rate in the treatment of PID-induced infertility.

Effect of therapies for kidney-tonifying and blood-activating in treatment of anovulatory infertility in eugenics / 中国中药杂志

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.

Professor MA Kun has summarized his experience in clinical and scientific studies for many years. And believes that kidney deficiency is the pathogenesis of HPRL and blood stasis is the dominant pathological manifestation of HPRL and can promote the progress of the disease. In view of this, Professor MA Kun took the therapy of kidney-tonifying and blood-activating as the principle for treating anovulatory infertility caused by HPRL, with soothing the liver and promoting Qi as adjuvant therapies. She has also summarized and refined the prescriptions for tonifying kidney and inducing ovulation, which have a remarkable clinical efficacy.

Advantages of integrated Chinese and western medicine in diagnosis and treatment of anovulatory infertility due to kidney deficiency and blood stasis / 中国中药杂志

Under the guidance of the theory of "kidney governing reproduction", this study demonstrated the mechanism of six types of ovulatory infertility caused by kidney deficiency and blood stasis, including anovulatory bleeding, polycystic ovary syndrome, hyperprolactinemia, luteinized unruptured follicle syndrome, luteal phase deficiency, and primary ovarian insufficiency. A series of studies have confirmed that integrated Chinese and western medicine can increase the responsiveness of the ovaries to gonadotropins and improve ovarian function by regulating the effects of estradiol(E_2), prolactin(PRL), and reducing follicle-stimulating hormone(FSH), luteinizing hormone(LH), progestin(P), and testosterone(T). It can also improve ovulation rate and pregnancy success rate by promoting follicle development, discharging, and synchronizing endometrial growth. This study illustrated the diagnosis and treatment of ovulatory infertility caused by kidney deficiency and blood stasis with integrated traditional Chinese and Western medicine in the "disease-syndrome-symptom" research mode, and highlighted the traditional Chinese medicine(TCM) idea of differentiating diseases based on syndromes and unique advantages of the combination of disease differentiation and syndrome differentiation, and interpreted TCM principle of "treating different diseases with the same method".

Relationship between nutrients intake during pregnancy and the glycemic control effect in pregnant women with gestational diabetes mellitus / 北京大学学报(医学版)

OBJECTIVE@#To explore the relationship between nutrients intake during pregnancy and the glycemic control effect in pregnant women with gestational diabetes mellitus (GDM).@*METHODS@#Pregnant women for 25-35 gestational weeks who underwent prenatal examination and completed GDM diagnostic test in two third-class hospitals in Beijing from October 2015 to October 2017 were recruited to participate in the cohort study, and were investigated at enrollment, 2 weeks after enrollment, and delivery. The cross-sectional survey data 2 weeks after enrollment was used for this study. Among them, dietary survey used the 24 h dietary records to collect the food intake of the subjects for the past day, and the intake of energy, macronutrients and micronutrients, was calculated according to the Chinese Food Composition Table. Using the data of fasting blood glucose (FBG) collected by clinical information system and referring to the Chinese Guidelines for the Diagnosis and Treatment of Pregnancy Diabetes (2014), the GDM patients with FBG ≤5.3 mmol/L were divided into the well-control group, those with FBG >5.3 mmol/L were divided into poorly-control group, and pregnant women with normal glucose tolerance were consi-dered as the normal group. Binary Logistic regression was used to analyze the association between the nutrients intake and glycemic control effect in pregnant women with GDM.@*RESULTS@#A total of 227 pregnant women were enrolled, including 104 GDM patients and 123 normal pregnancy women. Among them, 76 subjects in the well-control group (73.1%, 76/104) and 28 subjects in the poorly-control group (26.9%, 28/104). Compared with the well-control group and the normal group, the protein intake and its energy ratio of the poorly-control group were significantly higher, while carbohydrate energy ratio was significantly lower. In terms of micronutrients, there was no significant difference between the well-control group and the poorly-control group. After adjusting for age, gestational age and physical activity level, with the well-control group as the control group, binary Logistic regression model showed that higher protein energy ratio was positively correlated with poorly glycemic control effect in pregnant women with GDM (OR=6.12, 95%CI: 1.44-25.98), while higher carbohydrate energy ratio was negatively correlated with poorly glycemic control (OR=0.54, 95%CI: 0.32-0.91).@*CONCLUSION@#Reduced protein intake and increased carbohydrate intake were associated with better glycemic control in pregnant women with GDM.
