ObjectiveTo explore the clinical efficacy of Dingkundan in the treatment of ovulation disorder infertility based on the real world and provide reliable evidence-based medical support for clinical practice. MethodClinical diagnosis and treatment data of patients with ovulation disorder infertility in the real world were collected through the Medroad Cloud system. Patients were grouped according to their real-world treatments， and the total effective rate， ovulation rate per cycle， number of days of follicle development， gonadotropin （Gn） dosage， levels of mature follicle-related hormones， endometrial thickness and classification， pregnancy rate per cycle， clinical pregnancy rate， ectopic pregnancy rate， and early pregnancy loss rate were observed. ResultA total of 207 patients were included， and the most common traditional Chinese medicine （TCM） syndrome in the entire population was liver depression and kidney deficiency. The patients were divided into a Chinese medicine group （Dingkundan， 60 cases）， a western medicine group （ovulation induction， 51 cases）， and a combination group （Dingkundan + ovulation induction， 96 cases）. The combination group（98.96%，95/96） had the highest total effective rate， which was statistically significant when compared with the Chinese medicine group（88.33%，53/60） （χ2=8.328， P<0.05）. The mature follicle estradiol （E2） and luteinizing hormone （LH） levels were the highest in the combination group， and there were statistically significant differences when compared with the western medicine group （P<0.01）. The endometrial thickness was higher in the Chinese medicine group and the combination group than in the western medicine group （P<0.01）. The proportion of type A endometrium was highest in the combination group（85.90%，201/234）， and there was a statistically significant difference when compared with the western medicine group（73.81%，93/126） （χ2=7.993， P<0.01）. The clinical pregnancy rate was 60.42%（58/96） in the combination group， which was higher than 36.67%（22/60） in the Chinese medicine group （χ2=8.336， P<0.01） and 39.22%（20/51） in the western medicine group （χ2=6.011， P<0.05）. Compared with the western medicine group， the combination group showed a favorable trend in total effective rate， ovulation rate per cycle， number of days of follicle development， Gn dosage， pregnancy rate per cycle， ectopic pregnancy rate， and early pregnancy loss rate， but the differences were not statistically significant. ConclusionIn real-world clinical practice， the combination of Dingkundan with ovulation induction can increase endometrial thickness， improve the proportion of type A endometrium， enhance egg quality， and increase the clinical pregnancy rate in patients with ovulation disorder infertility. This approach deserves further clinical research and application.

Synthesis of N-acyl glycine surfactant from palm oil as green repellent and toxicant to termite (Microcerotermes diversus).

This study described for the first time, the synthesis of a greener, safer, and more effective termiticide using a bio-based surfactant, N-acyl glycine derived from palm oil for the control of Microcerotermes diversus. Laboratory findings showed that the highest repellent activity was observed in N-acyl glycine surfactant (83.33%) at 50 ppm. In addition, N-acyl glycine surfactant also exhibited substantial time and concentration-dependent anti-termiticidal activity in which the highest termite mortality was observed after 3 days of exposure at 50 ppm of the surfactant (100%). Furthermore, 32.49 ppm concentration of N-acyl glycine surfactant (LC50 = 32.49 ppm) attained 50% of termite lethality. The current innovated termiticide with the use of N-acyl glycine surfactant offers a better efficacy, lower cost, and prevents the use of dangerous termiticides that are critical in creating a more sustainable environment, and controls Microcerotermes diversus at the same time.

Interpretation and reflection of Traditional Chinese Medicine registration evidence system in Canada / 国际中医中药杂志

Traditional Chinese Medicine (TCM) products could be registered as natural health products (NHPs) in Canada. Its registration process could be mainly divided into simple-application, traditional-application and non-traditional application. By analyzingi the TCM registration evidence system and its safety, effectiveness and quality required by different registration categories in Canada, we found that "simple-application" procesure needs to submit evidence based on the parameters of a component in the monograph. As for "traditional application", TCM products need to be used at least 50 years with, traditional material or Pharmacopoeia can be used as evidence; As for non-traditional application, TCM products need to provide evidence according to the disease risk level, and most of them need to provide scientific experiment evidence. Therefore, from the experience of TCM registration evidence system in Canada, the registration of TCM products should pay attention to improve the its classification method, refining its evidence requirements and data types, promoting the formulation of monograph of TCM, realizing the scientific evaluation and rapid review of classic famous prescriptions, and promoting the inheritance and innovative development of TCM in China.

Introduction and analysis of the registration process of Traditional Chinese Medicine as a natural health product in Canada / 国际中医中药杂志

At present, the registration process of Traditional Chinese Medicine (TCM) in Canada is refering to the requirements of Natural Health Products (NHPs). In terms of registration material, both NHPs and TCM include plants, animals and minerals with medicinal components, but the fundamental difference between them is that TCM is guided by the basic theory of TCM. As for the registration classification of TCM in Canada, first of all, judge whether the product to be applied for is NHPs; Secondly, we should clarify the types and ways of registration, mainly including simple application, traditional application and non-traditional application, and provide application forms, label texts, summary reports, evidence, animal tissue forms, finished product specifications and other materials according to different requirements. At present, the successful registration experience of TCM products in Canada mainly mainly includes applying for superior varieties, selecting appropriate application channels, communicating with local health management units and providing sufficient scientific evidence and good clinical application records. The regulations on the registration of NHPs in Canada have not fully considered the particularity of TCM and the registration of TCM products is still facing some difficulties. In the future, we can learn from the registration process and requirements of the Health Canada, promote the interconnection and mutual recognition of the Pharmacopoeia of the People's Republic of China and the NNHPD monographs in Canada, reduce the obstacles to the local application for registration of TCM, and promote the further improvement of the international standards of TCM.

Bushen Huatan recipe for treatment of polycystic ovary syndrome: therapeutic mechanism based on network pharmacology and molecular docking / 南方医科大学学报

OBJECTIVE@#To explore the pharmacological mechanism of Bushen Huatan (BSHT) recipe in the treatment of polycystic ovary syndrome (PCOS).@*METHODS@#The active ingredients in the component drugs of the recipe were screened through TCMSP, and their potential targets were predicted by PubChem and Swiss target prediction. Genecards and OMIM were used to screen the therapeutic targets in the treatment of PCOS. The drug targets and disease targets were corrected using Uniprot, and the intersection targets were obtained. The protein-protein interaction (PPI) network was constructed using STRING, and the intersection targets were analyzed with CytoNCA to screen the core targets. DAVID was used for GO enrichment analysis and KEGG pathway enrichment analysis, and the core components and core targets were verified using AutoDock. Animal experiment was performed to verify the results using a female C57BL/6J mouse model of PCOS, treated daily with 1 mg/kg BSHT recipe granule for 35 days, and the ovarian expressions of the core targets and pathways were detected using Western blotting.@*RESULTS@#We identified a total of 125 potential active ingredients from the 14 component drugs in the recipe, 990 drug targets, 4759 PCOS targets and 434 intersection targets. The core active ingredients of the recipe included β -Sitosterol, kaempferol, and quercetin, whose core targets included PIK3CA, PIK3R1, APP, AKT1, and MAPK1. GO enrichment analysis highlighted such processes as drug reaction, negative regulation of apoptosis, and positive regulation of transcription from RNA polymerase Ⅱ promoter. The enriched KEGG pathways included primarily the cancer pathway and PI3K-Akt signaling pathway. Molecular docking showed that the core active ingredients had strong binding ability with the core targets. In the animal experiment, BSHT recipe was shown to improve the symptoms, down-regulate the expressions of PI3K and Akt proteins and up-regulate MAPK1 expression in the ovary of mice with PCOS.@*CONCLUSION@#The therapeutic mechanism of BSHT recipe for PCOS involves multiple active ingredients, multiple therapeutic targets and multiple pathways.

Research Strategy of Mechanism of Efficacy Enhancing and Toxicity Reducing of Antibiotics Combined with Chinese Medicine for Infectious Diseases / 中国实验方剂学杂志

The decreased efficacy and severe side effects of antibiotics, as well the increase of multidrug resistant pathogens are seriously threatening human health. It has become an urgent task for the whole world to actively respond to threats and establish effective prevention and control plans. Traditional Chinese medicine (TCM) has a long history with exact curative effect in the treatment of infectious diseases. It not only inhibits pathogens and eliminates endotoxin, but also has therapeutic effect on inflammation, immune abnormality and overall disorder caused by infection. Antibiotics mainly inhibit the pathogen itself, while the combination of TCM and antibiotics is complementary with each other and is considered as a feasible solution to the challenges. Some clinical observations have shown that TCM has potentiality of enhancing antibiotics efficiency and reducing toxicity. Exploring its mechanism is the necessary measure to optimize and popularize treatment regimen. Firstly, multi-level and multi-dimensional systematic pharmacology network analysis methods are used to predict the mechanism of TCM combined with antibiotics in the treatment of infectious diseases, so as to provide the evidence for further empirical research and selection of test indicators. Then by following the principle of corresponding drug use in specific TCM syndromes, the antibiotics and TCM are individually and jointly applied to treat patients with specific syndrome conditions of infectious diseases. Besides routine and comprehensive evaluation of synergistic and attenuated effect of the combined drug use, multi-omics technique is also used to find the subtle effects of these two drugs at a molecular level. The sensitive and stable clinical biomarkers of synergism and attenuation of combined drug use are determined by using biomolecular network analysis technology. Finally, taking these biomarkers as clues, the biotransformation process and regulation mechanism of the biomarkers are traced back in animal models of infectious diseases and cell level, and all of these are clinically verified. As a result, the mechanism of efficacy enhancing and toxicity reducing of combined drug use can be revealed, providing basis for the promotion and application of such combined drug use.

To explore the influence for combination of nourishing yin and tonifying yang sequential therapy (NYTYST) with Western medicine in treating anovulatory infertility rats with diminished ovarian reserve (DOR) based on TGF-β1/Smads signaling pathway. 
 Methods: A total of 40 female rats were randomly divided into 5 groups, a normal control group, a model group, a Western medicine group, a NYTYST group and a combination group (n=8 in each group). The DOR model was established through orally taking tripterygium pill for continuous 2 weeks. The normal control group and the model group were treated with saline for 10 days. The Western medicine group was treated with hormone replacement therapy (HRT) and ovarian stimulation. The NYTYST group was treated with nourishing yin herbs in proestrus and tonifying yang herbs in late estrus and the combination group was treated with Chinese herb and Western drugs for 10 days. HE staining was used to observe histopathologic changes in ovary. Expression levels of transforming growth factor β1 receptor (TGF-β1R) in rats ovarian were detected by immunohistochemistry. Expression levels of Smad2, Smad3 and Smad7 protein in rat ovarian were detected by Western blot.
 Results: Compared with the control group, the numbers of developing follicles, mature follicles and corpus luteum were decreased , while atrefic follicles were increased significantly in the model group (P<0.01); the levels of TGF-β1R, Smad2 and Smad3 were decreased significantly, while Smad7 was increased significantly (P<0.01). Compared with the model group, the numbers of developing follicles, mature follicles and corpus luteum, Smad2 and Smad3 expression were increased, while atrefic follicles and Smad7 were decreased significantly in the treatment group (P<0.05 or P<0.01). The numbers of developing follicles and corpus luteum in the combination group was superior to the Western medicine group (P<0.05). Compared with the Western medicine group, the levels of TGF-β1R, Smad2 and Smad3 were increased significantly, while Smad7 was decreased significantly in the combination group (P<0.05 or P<0.01). 
 Conclusion: NYTYST combined with Western medicine can improve the function of ovaries reserve by up-regulation of TGF-β1R, Smad2 and Smad3 while down-regulation of Smad7 in DOR rats.

Effect of continuous light on reproductive rhythm of rats and intervention effect of Traditional Chinese Medicine / 医学研究生学报

Objective Light acts as an important zeitgeber and regulates the body's circadian rhythm.Excessive lighting at night leads to light pollution,which interferes with the circadian rhythm and thus adversely affects the body.To observe the adverse effect of continuous light on female reproductive endocrinology and explore effective treatment,the animal experiment was carried out.Methods 185 sexual maturity female SD rats in the age of 2 months with normal estrous cycle were enrolled.60 rats were selected randomly and enrolled into control group.Normal illumination conditions were given.The remaining rats were given 300±20lux light intensity for 24h/d last for 50 days to get reproductive rhythm disorder model.The model rats (100) were randomly divided into models group (n =50) and Traditional Chinese Medicine (TCM) group (n =50).Traditional Chinese Medicine group was treated with sequential TCM.At last we get 50 rats enrolled into model group and herbal group respectively.The TCM group rats were given therapy of nourishing yin and tonifying yang sequential TCM,while the two other groups were gavaged the same volume of physiological saline.The estrous cycle was observed in all groups.20 days later,blood were collected dynamically and E2 (estradiol),P (progesterone),LH (Luteinizing Hormone),FSH (Follicle-Stimulating Hormone)and melatonin were compared to evaluate the therapeutic effect of TCM.Finally,try to explain the mechanism of TCM's effect from the perspective of melatonin.Results At the first day,E2 was lower in TCM group and models group than control group (P＜ 0.05).At the second day,E2 was higher in traditional Chinese Medicine group than control group (9＜0.05).At the third day,E2 was higher in TCM group and models group than that in control group (P＜ 0.05).Progesterone in control group showed low level in pre-estrous and estrous period and elevated in the late stage of estrous.Progesterone showed no obvious change during the estrous cycle in TCM group and models group.At the third and fourth day,Progesterone was significantly lower in models group than TCM group and control group.At the first day,LH in models group [(249.8±50.2)mIU/mL] and TCM group [(83.4±37.3)mIU/mL] were significantly lower than control group [(430.0± 100.4)mIU/mL] (P＜0.05).At the first day,FSH in models group and TCM group were significantly lower than control group (P＜0.05).At the fourth day,FSH in TCM group was significantly lower than control group and models group (P＜0.05).Compared the melatonin among three groups,the circadian rhythm was high at night but low in the day in control group.The highest level was nearly 5 times higher than the lowest level.Neither the models group nor the TCM group had obvious recent rhythm changes.Conclusion Continuous light can induce disordered estrous cycle and loss of rhythm.Traditional Chinese Medicine can somehow induce circulation reconstruction.Continuous light can induce disordered endocrine,E2,FSH,LH surge abnormal,ovulation failure,luteal phase defect.TCM can induce ovulation and luteal support.Continuous light can destroy melatonin circadian rhythm and TCM can increase melatonin,which could be the mechanism of TCM's effect.

Research progress in microorganism changes of rhizospheric soil and root endogenous and ecology during continuous cropping of Panax notoginseng / 中草药

Panax notoginseng is one of the most important traditional Chinese medicinal herbs, and it is mainly distributed in Yunnan and Guangxi Provinces and only can be planted in a very narrow geographical environment. Its yield is significantly limited by continuous cropping obstacles in the cultivation process, which has seriously affected the application and development of P. notoginseng. The dynamic patterns of root and soil rhizosphere microbial community response were main reasons for the continuous cropping obstacle. In this paper, the dynamic changes of the root and rhizosphere systems, pathogenic microorganisms and symbiotic microorganisms in the formation of P. notoginseng continuous cropping obstacles were analyzed, and the progress in this field was summarized. Two methods for studying soil and root microorganism of continuous cropping process are proposed: 1. The dynamic analysis of microorganism in the rhizosphere and root of P. notoginseng must be completed with the method of pure-culture and culture-independent; 2. Quantitative analysis of main pathogenic microorganisms of P. notoginseng. It will provide theoretical basis for overcoming continuous cropping obstacles in plant of P. notoginseng.
