Medicarpin suppresses lung cancer cell growth in vitro and in vivo by inducing cell apoptosis.

Lung cancer (LC) is the leading cause of cancer deaths worldwide. Surgery, chemoradiotherapy, targeted therapy, and immunotherapy are considered dominant treatment strategies for LC in the clinic. However, drug resistance and meta-stasis are two major challenges in cancer therapies. Medicarpin (MED) is an isoflavone compound isolated from alfalfa, which is usually used in traditional medicine. This study was de sig ned to evaluate the anti-LC effect and reveal the underlying mechanisms of MED in vivo and in vitro. We found that MED could significantly inhibit proliferation, induce apoptosis, and cell cycle arrest of A549 and H157 cell lines. Basically, MED induced cell apoptosis of LC cells by upregu lating the expression of pro-apoptotic proteins BAX and Bak1, leading to the cleavage of caspase-3 (Casp3). Moreover, MED inhibited the proliferation of LC cells via downregulating the expression of proliferative protein Bid. Overall, MED inhibited LC cell growth in vitro and in vivo via suppressing cell proliferation and inducing cell apoptosis, suggesting the therapeutic potential of MED in treating LC.

[Identification of quality markers of Gei Herba based on analytic hierarchy process-entropy weight method and network pharmacology].

Analytic hierarchy process(AHP)-entropy weight method(EWM) and network pharmacology were employed to identify the potential quality markers(Q-markers) of Gei Herba. According to the new concept of Q-markers in traditional Chinese medicine(TCM), the AHP-EWM was applied to quantitatively identify the Q-markers of Gei Herba. The AHP was used for the weight analysis of primary indicators(factor layer), and the EWM for the analysis of literature and experimental data of secondary indicators(control layer). In addition, network pharmacology was employed to build the "component-target-disease-efficacy" network for Gei Herba, and the components showing strong associations with the Qi-replenishing, spleen-invigorating, blood-tonifying, Yin-nourishing, lung-moistening, and phlegm-resolving effects of Gei Herba were screened out. According to the results of AHP-EWM and network pharmacology, four components, i.e., ellagic acid, gallic acid, gemin G, and gemin C, were finally identified as potential Q-markers of Gei Herba. In this study, the AHP-EWM and network pharmacology were employed to screen the Q-markers of Gei Herba, which provided ideas for the quantitative evaluation and identification of Q-markers of TCM.

Electroacupuncture alleviates ciliary muscle cell apoptosis in lens-induced myopic guinea pigs through inhibiting the mitochondrial signaling pathway.

AIM: To investigate the effect of electroacupuncture (EA) on the mitochondria-dependent apoptotic signaling pathway in the ciliary muscle of guinea pigs with negative lens-induced myopia (LIM). METHODS: Guinea pigs were randomly divided into normal control (NC) group, LIM group, LIM+SHAM acupoint (LIM+SHAM) group, and LIM+EA group. Animals in the NC group received no intervention, while those in other three groups were covered with -6.0 diopter (D) lenses on right eyes. Meanwhile, animals in the LIM+EA group received EA at Hegu (LI4) combined with Taiyang (EX-HN5) acupoints, while those in the LIM+SHAM group were treated at sham points. After treatments for 1, 2, and 4wk, morphological changes in ciliary muscles were observed with hematoxylin and eosin (H&E) staining and nick end labeling (TUNEL), and the expression of the mitochondrial apoptotic signaling pathway-related molecules in ciliary muscles was measured by real-time quantitative polymerase chain reaction (qPCR) and Western blot. Additionally, the adenosine triphosphate (ATP) contents were also determined in ciliary muscles. RESULTS: Axial length increased significantly in the LIM and LIM+SHAM groups and decreased in the LIM+EA group. The ciliary muscle fibers were broken and destroyed in both LIM and LIM+SHAM groups, whereas those in the LIM+EA group improved significantly. TUNEL assay showed the number of apoptotic cells increased in the LIM and LIM+SHAM groups, whereas reduced in the LIM+EA group. ATP contents showed a significant decrease in the LIM and LIM+SHAM groups, whereas increased after EA treatment. Compared with the NC group, the dynamin-related protein 1 (DRP1), Caspase3, and apoptotic protease activator 1 (APAF1) levels were significantly increased in the LIM group and decreased in the LIM+EA group. CONCLUSION: The results provide evidence of EA inhibiting the development of myopia by regulating the mitochondrial apoptotic signaling pathway.

Effect of BBM gene on callus growth and ginsenoside content in Panax quinquefolius / 中国中药杂志

Baby Boom(BBM) gene is a key regulatory factor in embryonic development and regeneration, cell proliferation, callus growth, and differentiation promotion. Since the genetic transformation system of Panax quinquefolius is unstable with low efficiency and long period, this study attempted to transfer BBM gene of Zea mays to P. quinquefolius callus by gene gunship to investigate its effect on the callus growth and ginsenoside content, laying a foundation for establishing efficient genetic transformation system of P. quinquefolius. Four transgenic callus of P. quinquefolius with different transformation events were obtained by screening for glufosinate ammonium resistance and molecular identification by PCR. The growth state and growth rate of wild-type and transgenic callus were compared in the same growth period. The content of ginsenoside in transgenic callus was determined by ultra-high performance liquid chromatography-triple quadrupole mass spectrometry(UPLC-MS/MS). The results showed that transgenic callus growth rate was significantly higher than that of wild-type callus. In addition, the content of ginsenoside Rb_1, Rg_1, Ro, and Re was significantly higher than that in wild-type callus. The paper preliminarily proved the function of BBM gene in promoting growth rate and increasing ginsenoside content, which provided a scientific basis to establish a stable and efficient genetic transformation system for Panax plants in the future.

Bioinformatics analysis and function prediction of ginseng TCP transcription factor family / 中国中药杂志

The longevity mechanism of ginseng(Panax ginseng) is related to its strong meristematic ability. In this paper, this study used bioinformatic methods to identify the members of the ginseng TCP gene family in the whole genome and analyzed their sequence characteristics. Then, quantitative real-time fluorescent PCR was performed to analyze the TCP genes containing elements rela-ted to meristem expression in the taproots, fibrous roots, stems, and leaves. According to the data, this study further explored the expression specificity of TCP genes in ginseng tissues, which facilitated the dissection of the longevity mechanism of ginseng. The ginseng TCP members were identified and analyzed using PlantTFDB, ExPASy, MEME, PLANTCARE, TBtools, MEGA and DNAMAN. The results demonstrated that there were 60 TCP gene family members in ginseng, and they could be divided into two classes: Class Ⅰ and Class Ⅱ, in which the Class Ⅱ possessed two subclasses: CYC-TCP and CIN-TCP. The deduced TCP proteins in ginseng had the length of 128-793 aa, the isoelectric point of 4.49-9.84 and the relative molecular mass of 14.2-89.3 kDa. They all contained the basic helix-loop-helix(bHLH) domain. There are a variety of stress response-related cis-acting elements in the promoter regions of ginseng TCP genes, and PgTCP20-PgTCP24 contained the elements associated with meristematic expression. The transcription levels of PgTCP20-PgTCP24 were high in fibrous roots and leaves, but low in stems, indicating the tissue-specific expression of ginseng TCP genes. The Class Ⅰ TCP members which contained PgTCP20-PgTCP23, may be important regulators for the growth and development of ginseng roots.

The linear correlation, platelet inhibition and the consistency of drug efficacy interpretation results in platelet Adenosine diphosphate (ADP) and Arachidonic acid (AA) pathway respectively between the three subgroups were compared. 【Results】 (1) In the MA<25mm group, the inhibition rates of ADP and AA pathway in platelet of A cup, A adjuvant and functional fibrin cup subgroups were (32.00±17.44) % vs (30.19±17.44) % vs (30.07±16.18) %, (24.3±33.53) % vs (22.53±30.9) % vs (22.37±31.2) %, respectively (R2 were all>0.975); (2) In the MA≥25 mm group, the inhibition rates of ADP and AA pathway in platelet of A cup, A adjuvant and functional fibrin cup subgroups were (34.34±33.59) % vs (18.45±24.42) % vs (18.01±24.33) %, (23.19±39.33) % vs (8.48±21.75) % vs (8.31±21.7) % ( R2 between the A cup group and the A adjuvant group were all<0.8, and R2 between the A adjuvant group and the functional fibrinogen cup group were all >0.975); (3)Take the test result of the functional fibrinogen cup as the standard, the correct rates of ADP and AA pathway drug efficacy interpretation were 82% (41/50) vs 100% (50/50) and 84% (42/50) vs 100% (50/50) respectively (P<0.05) between the A-cup group and the A adjuvant group, while the interpretation results of drug efficacy of the two pathway were consistent between the A adjuvant group and the functional fibrin cup group (P>0.05). 【Conclusion】 Adding A adjuvant to TEG platelet aggregation function test can effectively inhibit non-specifically activated platelets in the A cup in the detection of platelet aggregation function, truly reflect the function of fibrinogen and improve the accuracy of platelet inhibition rate.

Novel technologies and models for studying pharmacological activities of traditional Chinese medicine for promoting blood circulation and removing blood stasis / 中国药理学与毒理学杂志

OBJECTIVE Our previous studies demonstrated that various ingredients from the traditional Chinese medicine (TCM) for promoting blood circulation and removing blood stasis, as exemplified by cryptotanshinone and salvi?anolic acid B, exerted striking effects on modulating angiogenesis and vascular permeability, which suggests that they may be effective in treating vascular leak-driven diseases (e.g. tumor, cerebral cavernous malformation and diabetic reti?nopathy). However, the lack of reliable and advanced technologies and models sets up difficult hurdles for better under?standing the role of TCM for promoting blood circulation and removing blood stasis. To this end, this study is to outline numerous cutting-edge platforms that can be utilized for exploring the function of TCM for promoting blood circulation and removing blood stasis in vascular leak-driven diseases. METHODS Two-photon laser scanning fluorescence micros?copy was used to observe the interactions between neutrophils and blood vessels in a real-time manner. Dynamic flow system was employed to mimic the in vivo behaviors of neutrophils. RIP1-Tag5 spontaneous pancreatic cancer model was used to study the function of tumor blood vessels. CCM2ECKO (deletion of CCM2 in endothelial cells) mice were employed to establish the cerebral cavernous malformation (CCM) animal model. Micro-computed tomography (micro-CT) was utilized to assess the CCM lesion. Müller cell-knockout mouse model was used to study the progression of dia?betic retinopathy. Vascular permeability in this model was assessed by fluorescein angiography. RESULTS The interac?tions between neutrophils and endothelial cells involve a series of complicated processes, including rolling, adhesion, intraluminal crawling and transmigration, which were all monitored in vivo by two-photon laser scanning fluorescence microscopy in a real-time manner. Dynamic flow system was capable of recapitulating the biological behaviors of neutro?phils in vitro. Tumor vascular function in particular vascular perfusion could be assessed in the RIP1-Tag5 spontaneous pancreatic cancer model. In terms of CCM studies, specific deletion of CCM2 in endothelial cells resulted in the initiation of CCM lesion. The size and number of CCM lesions could be visualized and quantified by micro-CT. Furthermore, the Müller cell-knockout mouse model was able to precisely reflect the clinical symptoms of diabetic retinopathy. Vascular leak could be monitored at different time points using fluorescein angiography. CONCLUSION An array of high technol?ogies and animal models can be used in investigating the occurrence and progression of multiple vascular leak-driven diseases. The pre-clinical and clinical studies of TCM for promoting blood circulation and removing blood stasis provide fundamental support for the application of the above-mentioned platforms, with the purpose of uncovering the scientific basis of TCM for promoting blood circulation and removing blood stasis.

Objective@#To evaluate the clinical efficacy of Compound Chamomile and Lidocaine Hydrochloride Gel for postoperative hypospadias in children.@*METHODS@#From January to December 2020, we treated 116 children with distal hypospadias in the Department of Urology, Department of Pediatrics and the Seventh Medical Center of the PLA General Hospital, 58 by primary Snodgrass urethroplasty only (the control group) and the other 58 with Compound Chamomile and Lidocaine Hydrochloride Gel smeared on the penis postoperatively in addition (the trial group). We compared the operation time and postoperative pain score, edema regression and incidence of infection between the two groups, followed by statistical analysis using T test and Chi-square test.@*RESULTS@#All the operations were successfully completed by the same surgeon under general anesthesia. There were no statistically significant differences between the trial and control groups in age (［2.5 ± 0.8］ vs ［2.4 ± 0.6］ yr, P > 0.05) or operation time (［95.6 ± 14.5］ vs ［97.1 ± 15.2］ min, P > 0.05). No incision infection occurred in any of the cases. The pain scores at dressing removal were remarkably lower in the trial than in the control group at 2 hours (1.4 ± 1.0 vs 2.6 ± 1.3, P < 0.05), 24 hours (2.2 ± 1.3 vs 3.9 ± 1.6, P < 0.05), 48 hours (1.2 ± 0.7 vs 1.6 ± 0.9, P < 0.05) and 72 hours after surgery (2.5 ± 0.8 vs 3.7 ± 1.8, P < 0.05). Significantly more cases of edema regression were achieved in the trial than in the control group at 2 weeks postoperatively (35 vs 19, P < 0.05).@*CONCLUSIONS@#Compound Chamomile and Lidocaine Hydrochloride Gel can effectively relieve pain, reduce edema and accelerate edema regression after surgery in children with hypospadias, and therefore deserves wide clinical application.、.

Systematic review and Meta-analysis of safety of Sanfu acupoint herbal patching in randomized controlled trial / 中国中药杂志

In order to systematically evaluate the safety of Sanfu acupoint herbal patching, CNKI, SinoMed, VIP, Wanfang, PubMed, Medline, EMbase, and Cochrane Library were searched in accordance with PICOS principles, with a time limit from database establishment to December 2019. Meta-analysis was used for a single-group rate analysis and a weighted combination of these two groups on rates of adverse reactions. A total of 9 articles meeting the inclusion criteria were included in the analysis, involving 2 119 patients. The single-group rate Meta-analysis showed that the adverse reactions incidence was 9% in the treatment group(OR=0.10,95%CI[0.06, 0.19], P<0.000 01), and 9% in the control group(OR=0.10, 95%CI[0.07, 0.13], P<0.000 01). In combined statistics of all samples OR=1.81, 95%CI[1.04, 3.15], P=0.04, the incidence of adverse reactions in the treatment group was slightly higher than that of the control group. In the subgroup analysis, the incidence of adverse reactions in terms of both single-group rate and weighed rate in the treatment group was higher than that in the control group in the asthma subgroup, rhinitis subgroup, ≥18 years old subgroup, and application time 2 h subgroup, with statistically significant differences(P<0.05). The results of the Meta-analysis and systematic review suggested that the incidence of adverse reactions in clinical use of the Sanfu acupoints herbal patching was relatively low. The main types of adverse reactions were skin ulcers, blisters and other skin symptoms. The symptoms were relatively mild, which could be relieved by drug withdrawal or symptomatic treatment. It shows that the safety of the Sanfu acupoint herbal patching was relatively high, and the occurrence of adverse reactions was related to the original disease and age, mainly in asthma and rhinitis or patients over 40 years old. Affected by clinical heterogeneity, the conclusions of the application time subgroup need to be further improved.

The females(with the males as reference, OR=1.076, 95% CI 1.018-1.137) and central population(with the east as reference, OR=1.235, 95% CI 1.048-1.456), people with Chinese medicine health culture literacy(with the people who do not have Chinese medicine health culture literacy as reference, OR=2.363, 95% CI 1.976-2.827) had a higher probability of acquiring Chinese medicine health culture knowledge through the Internet. Referring to people who were illiterate or less literate,the OR values of people who went to elementary school, junior school, high school/vocational/technical school and junior college/university was 2.396(95% CI 2.062-2.784),4.481(95% CI 3.751-5.352), 6.687(95% CI 5.541-8.07),and 9.109(95% CI 7.385-11.235). The higher the age, the lower the probability of acquiring Chinese medicine health culture knowledge through the Internet. Taking civil servants as a reference, teachers, students, farmers, and workers had a low probability of acquiring Chinese medicine health culture knowledge through the Internet. The OR values was 0.736(95% CI 0.548-0.988),0.609(95% CI 0.449-0.826), 0.424(95% CI 0.325-0.554),and 0.707(95% CI 0.539-0.927). Regions, gender, age, education level, occupation, and possession of Chinese medicine health culture literacy are factors influencing whether residents obtain Chinese medicine health culture knowledge through the Internet.

Specific PCR Method for Identification of Medicinal Scolopendra / 中国实验方剂学杂志

Objective: Scolopendra was a traditional Chinese medicine(TCM) with a good medicinal value. Nowadays, there have been increasingly more adulterates of Scolopendra in the medicine market. To ensure the safe and effectiveness of clinical medicines,a convenient and accurate specific polymerase chain reaction(PCR) method for identification of medicinal Scolopendra from its common adulterates was established. Method: Based on the differences of COI gene DNA sequences among Scolopendra subspinipes mutilans and adulterants,the specific primer was designed,the reaction conditions were optimized,and the PCR method for identification was explored and verified in terms of tolerance and feasibility. Besides,the original animal samples and medicine of Scolopendra were collected. Result: Through the established PCR reaction system,the bright and simple fragments of 500 bp was amplified from DNA templates of S. subspinipes mutilans. All of the adulterants were negative by the multiplex PCR assay,such as S. multidens,S. subspinipes,S. dehaani,S. hainanum. Conclusion: The identified primer is highly specific,and the specific PCR method established in this paper can accurately identify Scolopendra and its adulterants, so as to provide an excellent scientific basis for the identification of TCM Scolopendra. The method is simple and intuitive, and facilitates wide promotion and application of the method, with a broad application prospect in the identification of TCM.

Analysis on the current status of the resource and service of traditional Korean medicine / 国际中医中药杂志

To explore the development tendency and major influential factors of traditional Korean medicine (TKM) resource and service by statistics analysis. Data are mainly from the Yearbook of Traditional Korean Medicine (2009-2015). Ministry of Health and Welfare Statistical Yearbook 2016, and the Ministry of health and welfare practicing qualification management system. This article analyzed the related indicators, such as the average annual growth rates and the proportion in the national medical system. From 2006 to 2015, the average annual growth rate of the number of TKM hospital and TKM clinics were 7.0％ and 3.2％ separately; the average annual growth rate of TKM doctor and TKM pharmacists were 4.3％ and 10.0％ separately; the average annual growth rate of the number of beds in TKM institutions were 9.3％; and the average annual growth rate of the number of applications for outpatient and inpatient reimbursement for medical insurance of TKM institutions were 12.3％ and 20.5％ separately. From 2006 to 2015, the resources and services of TKM presented an increasing tendency, and the accessibility of TKM resource and service was enhanced. It is suggested that China should use reference from the aspects of strengthening policy, expanding the sources of capital investment, and expanding the coverage of medical insurance.

Multiplex PCR to simultaneous identification of five traditional Chinese medicinal seahorses / 中国中药杂志

Seahorse is one the most commonly used medicinal animal in China. Five species of Hippocampus are recorded as seahorse in the Chinese Pharmacopoeia. Because of the rapid decrease, several other Hippocampus species are often adulterants as medicinal seahorse in the herbal market, which compromise clinical efficacy and pose threat to endangered seahorse species conversation. Herein, a multiplex polymerase chain reaction (mPCR) method was developed to identify the biological sources of medicinal seahorses.Based on the sequences of mitochondrial DNA, five specific primers for Hippocampus trimaculatus, H. kelloggi, H. kuda, H. histrix and H. mohnikei (H. japonicus)were designed, respectively. Multiplex PCR yields the products of 155, 222, 292, 352, 458 bp amplicons in the present of DNA templates of H. kuda, H. mohnikei, H. kelloggi, H. histrix and H. trimaculatus, respectively. This multiplex PCR method which electrophoresis migration of different lengths of DNA bands allowed simultaneous identification of all the five medicinal seahorses in a single assay. It showed that this multiplex PCR assay is useful for the simultaneous identification the biological sources of complex multi-source samples, which could provide a useful tool for the quality control of seahorses.

Zoological origin survey of commercial hippocampus in Chinese herbal markets by morphological and DNA sequencing identification / 中国中药杂志

Hippocampus is a precious animal medicine in Chinese herbal medicines. Numerous seahorse species possessing similar morphology were used as commercial hippocampus in herbal markets. Clarifing the zoological of commercial hippocampus in herbal markets is a crucial issue, which contributed to establish authentication and quality control standard. This study investigated 1 156 dried seahorse samples collected from eight main herbal markets using CO Ⅰ fragment DNA sequencing coupling with morphological identification. The results showed that 23 seahorse species were present in the China TCM market. Among them, five species were officially listed in China Pharmacopoeia, seven species namely winged seahorse (Hippocampus alatus), giraffe seahorse (H. camelopardalis), knysna seahorse (H. capensis), beibuwan seahorse (H. casscsio), half-spiny seahorse (H. semispinosus), Europe seahorse (H. hippocampus), zebra seahorse (H. zebra) were found in herbal markets for the first time. The present DNA sequences analysis coupling with morphological identification method could also use to survey the species origin of other Chinese herbal medicines in herbal markets.
