The human use experience of traditional Chinese medicine(TCM) is of great significance for the development of new traditional Chinese medicine. In 2023, the National Medical Products Administration(NMPA) issued the Special Regulations on Registration Management of Traditional Chinese Medicine, which explicitly encouraged the conduct of high-quality human use experience research on TCM clinical practice to obtain sufficient evidence for registration support. It also required that human use experience research should comply with relevant requirements and undergo registration verification. The quality of human use experience research on TCM directly determines the reliability of the evidence. This article discussed the quality requirements for human use experience research on TCM from the perspectives of basic requirements, organizational management, key pharmaceutical information, scientific research, risk management, ethical compliance, and study implementation and proposed differential treatment in quality requirements and registration verification focus based on different research purposes, stages, and types of studies. While ensuring the authenticity of data, retrospective studies should pay particular attention to the integrity of the data, and prospective studies should focus on the normativity of the data, which may affect the research conclusions. Human use experience research, as part of drug registration materials, falls within the scope of relevant regulatory oversight. Researchers should have a strong awareness of regulations to avoid serious quality issues. The standardized conduct of human use experience research on TCM requires joint efforts from regulatory authorities, applicants, research institutions, and researchers to establish a research quality management system based on the clinical characteristics of TCM.

Evidence-based medicine plays an important role in promoting the scientific nature of clinical decision-making. Howe-ver, there is a problem where evidence derived from clinical research may not necessarily be applicable to individual patients. Evidence-based medicine has been introduced into the field of traditional Chinese medicine(TCM) for over 20 years, and although certain achievements have been made, the overall level of clinical research evidence based on the principles of evidence-based medicine in TCM is not high. The acceptance of TCM diagnosis and treatment guidelines developed based on evidence-based medicine methods is generally low. As revealed by the analysis of the problems in the application of evidence-based medicine in the field of TCM, it is found that there is a structural contradiction between clinical randomized controlled trial(RCT) of TCM and the characteristics of TCM clinical practice. They cannot comprehensively, objectively, and truthfully reflect the clinical efficacy and safety of TCM. Conducting clinical RCTs of TCM in pursuit of "evidence" actually means giving up the advantages of TCM in clinical treatment based on syndrome differentiation, prescription changes along with syndromes, and treatment in accordance with three categories of disease cause, which leads to sacrificing some clinical effectiveness of TCM. Based on the concept of evidence-based medicine, this article proposed the construction of "clinical syndrome-based medicine" based on the optimal clinical experience, which was suitable for the characteristics of TCM clinical practice. The key to clinical syndrome-based medicine is the optimal clinical experience, and the core elements of the optimal clinical experience are regularity and reproducibility. Real-world research methods are recommended as a reference for obtaining the optimal clinical experience. Clinical syndrome-based medicine, combining the characteristics of TCM clinical practice and incorporating the concept of evidence-based medicine, is the product of integrating TCM into evidence-based medicine. It is dedicated to improving the clinical efficacy of TCM along with evidence-based medicine.

Ovarian cancer is one of the three major cancers in gynecology. Ovarian cancer has insidious symptoms in its early stages and mostly has progressed to advanced stages when detected. Surgical treatment combined with chemotherapy is currently the main treatment, but the 5-year survival rate is still less than 45%. Angiogenesis is a key step in the growth and metastasis of ovarian cancer. The inhibition of ovarian cancer angiogenesis has become a new hotspot in anti-tumor targeted therapy, which has many advantages such as less drug resistance, high specificity, few side effects, and broad anti-tumor spectrum. Modern research has confirmed that traditional Chinese medicine(TCM) can inhibit tumor angiogenesis by inhibiting the expression of pro-angiogenic factors, up-regulating the expression of anti-angiogenic factors, inhibiting the proliferation of vascular endothelial cells, reducing the density of tumor microvessels, and regulating related signaling pathways, with unique advantages in the treatment of ovarian cancer. This paper presented a review of the role of TCM in inhibiting ovarian cancer angiogenesis in order to provide references for the optimization of clinical ovarian cancer treatment strategies.

Human use experience(HUE) is important for the research and development of Chinese medicine. For the sake of more reliable data, the Professional Committee for Clinical Evaluation of Chinese Medicine of Chinese Pharmaceutical Association drafted the Expert Consensus on Human Use Experience Research of Traditional Chinese Medicine. It highlights that the research on HUE should have clear purposes, describe the theoretical basis of traditional Chinese medicine(TCM) for the clinical indications and prescriptions and the clinical value of prescriptions, especially the advantages or characteristics in clinical orientation and target population, evaluate the dosages and number of medicinals of prescriptions, verify the accordance with the preparation process of new Chinese medicine, analyze feasibility of the process for large-scale production and the rationality of the dosage form, and assess the medicinal material resources. Moreover, such research should have reasonable protocol and the collection of clinical data on HUE must comply with medical ethics and avoid conflicts of interest. The collection method should be selected depending on the characteristics of clinical data. Quality control measures should be formulated to ensure the authenticity, accuracy, completeness, reliability, and traceability of clinical data. The definitions on the clinical data should be uniform and clear, and methods should be adopted to avoid bias. The data can be statistically analyzed after the processing. Through the study of HUE, the clinical orientation, target population, commonly used dosage, course of treatment, preliminary efficacy and safety of Chinese medicine prescriptions will be clarified. On this basis, the data on the HUE should be discussed and conclusions will be drawn. Finally, a standardized report will be formed.

OBJECTIVE:
To explore the mechanism of catgut embedding at back- points on nonalcoholic steatohepatitis (NASH) in rats based on IKK/IKB/NF-κB signaling pathway and downstream inflammatory factors.
METHODS:
Eighty SPF SD rats were selected, among them 10 rats were selected divided into a normal group (group A), and the remaining 70 rats were fed with high-fat diet to establish NASH model. At the end of 12 weeks, 10 rats were randomly selected to verify whether the model establishment was successful. Then the remaining 60 rats were randomly divided into a model group (group B), a catgut embedding at back- points group (group C), a catgut embedding at abdominal points group (group D), an acupuncture at back- points group (group E), a sham catgut embedding group (group F) and a western medication group (group G), 10 rats in each group. The rats in the group C were treated with catgut embedding at "Ganshu" (BL 18), "Pishu" (BL 20), "Weishu" (BL 21) and "Shenshu" (BL 23); the rats in the group D were treated with catgut embedding at "Daheng" (SP 15), "Fujie" (SP 14), "Huaroumen" (ST 24) and "Tianshu" (ST 25); the rats in the group E were treated with acupuncture at the same acupoints as the group C; the rats in the group F were treated with catgut embedding at back- points but the needle did not enter subcutaneous tissue gamma; the rats in the group G were treated with intragastric administration of vitamin E capsule. All the treatment was given for 4 weeks. The rats in the group A were fed with normal diet until the end of 16 weeks without any intervention. The rats in the group B continued to be fed with high-fat diet until the end of 16 weeks. After the intervention, the liver index was calculated; the liver histomorphology was observed by HE staining; the liver function [alanine aminotransferase (ALT), gamma glutamyl transferase (γ-GGT), alkaline phosphatase (ALP)] and blood lipid [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL)] were measured by serum biochemistry. The serum levels of TNF-α, IL-6 and IL-1βwere detected by ELISA, and the expressions of IKK-α, NF-κBp65, IL-6, IL-1β and TNF-α proteins in liver tissue were detected by Western blot. The temperature of the conception vessel and the governor vessel was measured by infrared thermography.
RESULTS:
Compared with the group A, the obvious steatosis and inflammatory cell infiltration were observed in the group B, and the body weight, liver wet-weight and liver index were all increased (<0.01). Compared with the group B, the liver tissue morphology in the group C, the group D, the group E and the group G was improved in varying degrees, and the liver index was decreased (<0.05), which was the most significant in the group C (<0.05). Compared with the group A, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β were all increased in the group B (<0.01); compared with the group B, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β in all intervention groups were all decreased in varying degrees (<0.01, <0.05), which was the most significant in the group C (<0.01). Compare with the group A, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in the group B were all increased (<0.01); compared with the group B, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in all intervention groups were decreased in varying degrees (<0.05), which was the most significant in the group C (<0.01). Compared with the group A, the temperature of the conception vessel and governor vessel was decreased in the group B (<0.01). Compared with the group B, the temperature of the conception vessel and governor vessel was all increased in the group C, the group D and the group E (<0.01); the temperature of the conception vessel in the group C was similar to that in the group D (>0.05), while the temperature of the governor vessel in the group C was superior to that in the group D (<0.05).
CONCLUSION
The catgut embedding at back- points might inhibit the activation of IKK/IKB/NF-κB signaling pathway to interrupt the inflammatory cascade, and reduce the "second hit" of inflammatory factors on liver, which could slow down NASH progress and prevent and treat NASH.

【Objective】To explore the role of lncRNA Xist in proliferation and migration of rat bone marrow mesenchymal stem cells(BMSC)and its possible mechanism.【Methods】BMSC were isolated,cultured and identified from the femur and tibia of 3 weeks old SD female rats in vitro. SiRNAs was designed and screened to acquire a high silencing efficiency siRNA. Lipo2000 was used to transfected si- Xist and si- NC into BMSC of the experimental group(si- Xist group)and the control group(si-NC group). BMSC proliferation capacity was determined by CCK-8 assay. The transverse and longitudinal mobility of BMSC were measured by wound healing assay and transwell migration assays. QPCR was performed to verify the silencing efficiency of lncRNA Xist and detect the expression levels of SDF- 1 and CXCR4 mRNA. Western blot was used to quantify the expression of CXCR4 protein.【Results】The P3 generation BMSC shows shuttle- like or whirlpool-like,and flow cytometry showed CD11b(-),CD34(-),CD45(-),CD44(+),CD90(+),CD105(+). When siRNAs were used to interfere with the expression of lncRNA Xist in BMSC ,the silencing efficiency of three siRNAs was 67.92% ,68.72% and 98.32% ,respectively. CCK- 8 assay showed that the OD450 value of si- Xist group decreased compared with si-NC group at 24 h and 48 h(P < 0.001,P < 0.01,respectively)and had no statistical difference at 12 h(P > 0.05). Wound healing assay showed that the wound healing percentage of si-Xist group was lower than that of si-NC group(P < 0.05);and the transwell migration assay showed that,compared with si- NC group,the cells that migrated through the polycarbonate membrane were obviously decreased at 6 h(P < 0.001). QPCR experiment showed that CXCR4 expression in si-Xist group was lower than that in si-NC group at mRNA level(P < 0.05),while SDF-1 expression showed no significant statistical difference(P > 0.05). Western blotting confirmed that CXCR4 expression in si- Xist group was lower than that in si-NC group(P < 0.05).【Conclusions】LncRNA Xist promotes proliferation and migration of rat BMSC by regulating CXCR4 expression.

The application of special acupoints for different primary symptoms of chronic gastritis in ancient literature of acupuncture and moxibustion was analyzed and summarized. With keywords, electronic and manual retrieval of ancient literature being performed to establish a database, the association rules were performed with SPSS Modeler 18. As a result, ① among all the 2243 items included, 109 items mentioned special acupoints (excluding those only mentioned crossing acupoint). The frequency of special acupoints was 2554 (71.7%), and the special acupoints on the spleen meridian, the stomach meridian, the conception vessel were frequently used. The frequency of five- point was highest, followed by front- points. ② The special acupoints for four main primary symptoms of chronic gastritis, "stomachache" "vomiting and regurgitation" "belching and acid regurgitation" and "epigastric fullness", included Zusanli (ST 36), Neiguan (PC 6), Zhongwan (CV 12), Gongsun (SP 4), Taibai (SP 3). In addition, the back- points were also selected to treat the primary symptoms other than "epigastric fullness". Zhangmen (LR 13) was added to treat "belching and acid regurgitation". The combination of Neiguan (PC 6) and Gongsun (SP 4) showed the strongest correlation; due to different primary symptoms, the combination had different emphasis.

Objective:To observe the effect of electroacupuncture (EA) pretreatment on adenine nucleotides in the myocardial tissues of the myocardial ischemia-reperfusion injury (MIRI) rats, and to explore the mechanism of EA pretreatment on myocardial prevention and protection in MIRI rats. Methods:Forty SPF male Sprague-Dawley (SD) rats were randomly divided into 5 groups: a blank group, a sham operation group, a model group, an EA at Neiguan (PC 6) group and an EA at Hegu (LI 4) group, with 8 rats in each group. Rats in the blank group only received binding to the rat plate, 30 min/time, once a day for 7 d; on the 7th day, rats in the sham operation group were subjected to threading for 40 min at the left anterior descending coronary artery without ligation, and then the rats were allowed to stand for 60 min before collection of the specimens; on the 7th day, rats in the model group were subjected to threading at the left anterior descending coronary artery with ligation, for 40 min before the blood flow was restored, and then the rats were allowed to stand for 60 min before collection of the specimens; on the 7th day of pretreatment with EA at Neiguan (PC 6) or Hegu (LI 4) for 30 min per day (once a day for 7 d), rats in the EA at Neiguan (PC 6) group and EA at Hegu (LI 4) group were subjected to modeling and sample collection same as in the model group. The left ventricular myocardium of the lower left anterior descending coronary artery was collected from rats in all 5 groups. Hematoxylin-eosin (HE) staining and transmission electron microscope (TEM) were used to observe the changes in myocardial pathological morphology. The change in the adenine nucleotide level of myocardial tissue was measured by high performance liquid chromatography (HPLC). Results:The HE staining and ultrastructure showed that the myocardial injury was severer in the model group compared with the sham operation group. Compared with the model group, the myocardial injury in the EA at Neiguan (PC 6) and the EA at Hegu (LI 4) groups was mild or hardly any. The adenine nucleotide levels in the sham operation group and the model group were all decreased compared with the blank group (allP<0.05); compared with the sham operation group, the adenine nucleotide level of the model group was also decreased, but the difference was not statistically significant (P>0.05); compared with the model group, the adenine nucleotide level in the EA at Neiguan (PC 6) group was increased (P<0.05), and the adenine nucleotide level in the EA at Hegu (LI 4) group was significantly increased (P<0.01). The adenine nucleotide level in the EA at Hegu (LI 4) group was higher than that in the EA at Neiguan (PC 6) group, but the difference was not statistically significant (P>0.05). Compared with the EA at Neiguan (PC 6) group, the levels of adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) in the EA at Hegu (LI 4) group were significantly increased (allP<0.01). Conclusion:Both EA at Neiguan (PC 6) and Hegu (LI 4) can alleviate the pathological damage to myocardium in MIRI rats, and increase the adenine nucleotide level in myocardial tissues, and thus protect MIRI rats. EA at Hegu (LI 4) has a better protective effect than Neiguan (PC 6).
10. Effect of Electroacupuncture at "Neiguan"(PC 6) on Serum and Myocardial Metabolites in Rats with Myocardial Ischemia Reperfusion Injury Based on Nuclear Magnetic Resonance Spectroscopy
Acupuncture Research 2018;43(3):152-162
OBJECTIVE: We have repeatedly demonstrated that electroacupuncture (EA) of "Neiguan"(PC 6) can improve myocardial ischemia in rats. The present study was designed to investigate the metabolomic profile of peripheral blood se-rum and myocardium involving EA-induced improvement of myocardial ischemia-reperfusion injury (MIRI) in rats by using nuclear magnetic resonance spectroscopy. METHODS: Thirty male SD rats were equally randomized into blank control, model and EA groups. Rats of the control group were only banded for 20 min, once a day for 7 days. The MIRI model was established by occlusion of the anterior descending branch of the left coronary artery for 40 min, followed by reperfusion for 60 min, and rats of the model group were banded as those in the control group. EA (10 Hz/50 Hz, 1 mA) was applied to bilateral PC 6 for 20 min, once daily for 7 days. The blood samples and left ventricular myocardial tissues were collected for assaying the profiles of differential metabolites using 1H nuclear magnetic resonance (1H NMR) spectroscopy and multivariate statistical analysis such as the principal components analysis (PCA), partial least squares-discriminant analysis (PLS-DA) and orthogonal PLS-DA (O-PLS-DA) with SIMCA-P software 12.0. RESULTS: A total of 19 differential metabolites (17 down-regulated, 2 up-regulated) in the serum and 14 differential metabolites (13 down-regulated and 1 up-regulated) in the ischemic left myocardium were identified after MIRI. Of the 19 serum differential metabolites, amino acids (leucine, isoleucine, valine,alanine, lysine, glycine, glutamine), 3-hydroxy butyric acid (3-HB), lactic acid, acetate, N-acetyl glycoprotein (NAc), acetone, acetoacetate, succinate, polyunsaturated fatty acids (PUFA), creatine, glycerophosphocholine (GPC) were down-regulated; while low density lipoprotein (LDL), LDL/very low density lipoprotein(LDL/VLDL)and glucose obviously up-regulated. Of the 14 myocardial differential metabolites, amino acids (alanine, lysine, glutamate, glutamine, aspartate, taurine, glycine, threonine), GPC, creatine, lactic acid, adenosine monophosphate (AMP), nicotinamide adenine dinucleotide (NAD+) were significantly decreased, and glucose was up-regulated. Following EA treatment, most of the decreased serum differential metabolites except acetone, acetoacetate and PUFA, and the increased serum LDL, LDL/VLDL and glucose recovered, basically close to the control level; and the decreased myocardial creatine, GPC and NAD+ were also apparently up-regulated and the increased myocardial glucose was down-regulated. But, myocardial threonine and AMP still presented a decreasing state. Although the pattern of myocardial differential metabolites of the EA group had a trend to be close to the control group, the significant difference still existed, while the metabolic pattern of serum metabolites in the EA group was close to that of the control group. CONCLUSION: EA stimulation of PC 6 can regulate serum or/and myocardial metabolites as amino acids, carbohydrates, lipids, etc. in MIRI rats, of which both serum and myocardial creatine, GPC and glucose may be jointly confer a favorable potential for EA-induced improvement of MIRI.
