ABSTRACT

The purpose of this study was to evaluate the economics of Annao Pills combined with antihypertensive drugs in the treatment of primary hypertension in the Chinese medical setting. TreeAge pro 2018 was used for cost-effect analysis and sensitivity analysis of the two treatment regimens. The intervention time of the simulation model was 2 weeks. The cost parameters were derived from Yaozhi.com, and the effect parameters were based on Meta-analysis of randomized controlled trial(RCT) involving Annao Pills. The experimental group was treated with Annao Pills combined with anti-hypertensive drugs(nifedipine controlled-release tablets + losartan potassium tablets), and the control group was treated with anti-hypertensive drugs(nifedipine controlled-release tablets + losartan potassium tablets). The basic analysis showed that the incremental cost-effect ratio(ICER) of the two groups was 2 678.67 yuan, which was less than 7.26% of the per capita disposable income in 2022. That is, compared with anti-hypertensive drugs alone, Annao Pills combined with antihypertensive drugs cost 2 678.67 yuan more for each additional patient with primary hypertension. The results of sensitivity analysis verified the robustness of the basic analysis results. The probability sensitivity results showed that when the patient's personal willingness to pay the price was higher than 2 650 yuan, the probability of the regimen in the experimental group was higher, which was consistent with the results of the basic analysis. In conclusion, when the price was higher than 2 650 yuan, Annao Pills combined with anti-hypertensive drugs was more economical than anti-hypertensive drugs alone in terms of improving the response rate of the patients with primary hypertension.

ABSTRACT

Due to the lack of specialized guidance, the post-marketing research on clinical effectiveness of Chinese patent medicines demonstrates varied quality and lacks high-quality evidence, failing to meet the demands of policy-making, clinical decision-making, and industrial decision-making. To address this issue, this project gathered experts in clinical medicine, clinical pharmacy, evidence-based medicine, drug epidemiology, medical ethics, and policy and regulation in China. They referred to the model of international post-marketing research on medicines and developed Guidelines for post-marketing research on clinical effectiveness of Chinese patent medicines under the framework of relevant laws and regulations and technical guidance documents in China. The guidelines were developed with consideration to the characteristics of Chinese patent medicines, China's national conditions, and all the stakeholders including marketing authorization holders, clinical researchers, drug administration, and users. The development of the guidelines followed the requirements for developing group standards set by the China Association of Chinese Medicine. The guidelines fully implement the concept of full life-cycle research, emphasizing the combination of traditional Chinese medicine(TCM) theory, human use experience, and clinical trials and pay attention to the compliance, scientificity, and ethics of research. The guidelines clarify the topic selection and decision-making path of the post-marketing research on effectiveness of Chinese patent medicines through six steps: determining research purpose, analyzing drug characteristics, evaluating research basis, proposing clinical orientation, clarifying research purpose, and implementing classified research. The general principles of research design and implementation were clarified from eight aspects: research type, research objects, sample size, efficacy indicators, bias, missing data, evidence level, and practicality. It focuses on the research on the TCM syndrome-based efficacy evaluation, clinical value-oriented mechanism of action, and the effectiveness of Chinese patent medicines with different routes of administration. The guidelines provide a universal methodological basis for the post-marketing research on clinical effectiveness of Chinese patent medicines.

ABSTRACT

With the premise of drug safety and effectiveness, pharmacoeconomic evaluation can provide optimal solutions for diversified decision-making application scenarios from different research perspectives while maximizing the rational utilization of existing healthcare resources. Chinese patent medicine is an essential component of pharmaceutical utilization in China and a significant part of healthcare expenditure in China. However, the economic evaluation of post-marketing Chinese patent medicine is lacking. These evaluations often lack standardization, exhibit varying quality, and are unable to effectively support healthcare decisions, indicating a need for improvement in overall quality. Given this situation, this project has gathered leading experts from China and has strictly adhered to the requirements of the group standards set by the China Association of Traditional Chinese Medicine in developing Guidelines for economic evaluation of post-marketing Chinese patent medicine, aiming to provide methodological guidance for the post-market pharmacoeconomic evaluation of Chinese patent medicine, enhancing the standardization of pharmacoeconomic evaluations of Chinese patent medicine and the scientific validity of research results, and thereby elevating the overall quality of pharmacoeconomic evaluations for post-marketing Chinese patent medicine. The guidelines adhere to the framework provided by relevant laws and regulations in China and technical guidance documents. It is based on guidance from traditional Chinese medicine(TCM) theories, focusing on the unique characteristics of TCM. It covers various aspects of pharmacoeconomic evaluation, including fundamental principles, research topic selection, research question definition, study design type selection, cost identification and measurement, health outcomes, and evaluation methods. The guidelines offer methodological recommendations and decision guidance to address common issues and challenges in the pharmacoeconomic evaluation of post-marketing Chinese patent medicine.

ABSTRACT

Magnetic polymer composites have been widely utilized in potential applications in material science, such as reduction of dyes, immunodiagnostics, biomedicals, and magnetically controllable photonic crystals owing to large surface areas, fast separation, and recyclable performance. In this work, anisotropic magnetic particles were prepared by seeded emulsion polymerization, with morphologies of "Fe3O4-shell", "hemisphere-like", "raspberry-like", "multiple lobes-like", and "sandwich-like". Poly(styrene/divinylbenzene/mono-2-(methacryloxy)ethyl succinate)@ Fe3O4 (P(St/DVB/MMES)@Fe3O4) were the seed microspheres, and P(St/DVB/MMES)@Fe3O4@polymer particles are achieved by seeded emulsion polymerizations. The morphology of the particles depends on polymerization conditions (monomer ratios and surfactant), particle properties, and so on. Then, the minimum surface free energy change principles were used to predict the equilibrium morphologies of the magnetic polymer composites. Through theory, the model gives the correct tendency and good agreement with the equilibrium morphology which was in tandem with TEM results. Lastly, after in situ surface deposition of Ag nanoparticles, magnetic composite particles with sandwich-like morphology were applied for the catalytic degradation of 4-nitrophenol (4-NP) reacting with NaBH4. The apparent rate coefficient is 0.0069 s-1, and it can keep mainly about 80% efficiency in catalysis after five cycles.

ABSTRACT

Wild plants represent a potential source of urban landscape trees. Stranvaesia davidiana Dcne. is a member of the Stranvaesia Lindl. Genus, which belongs to family Rosaceae Juss. It has great ornamental value. It can contribute to urban color foliage and fruit species. However, the most effective fertilizer application strategy required for its cultivation is unknown. Therefore, we conducted an orthogonal experiment to investigate the fertilizer type and level (pure nitrogen) using ten experimental groups, including an untreated control group. Pot experiments were used to determine the growth indices of seedlings, including plant height, basal diameter, and chlorophyll content post-fertilizer treatment. This study explored the most appropriate fertiler application model for the growth of S. davidiana seedlings. The results revealed that enhanced seedling growth depended on the type and amount of fertilizer used, and their interaction. Fertilizer application increased the plant height by 2.67 cm to 12.26 cm, basal diameter by 0.39 cm to 0.75 cm, and chlorophyll content by 5.66 to 19.86. Among the different types of fertilizer, organic fertilizer increased the plant height by 0.42 cm to 9.59 cm and basal diameter by 0.01 cm to 0.05 cm, compared with the control group. Organic fertilizer had the maximum effect on seedling growth, especially at medium levels. The total growth of basal diameter and chlorophyll content was 1.58 ± 0.04 cm and 39.53 ± 2.37, respectively. Basal diameter is the most critical index in seedling reproduction . The study results suggest that the application of 4.06 g of organic fertilizer per plant was the most effective, and served as a basis for further field trials.

ABSTRACT

Magnetic nanospheres are becoming a promising platform for a wide range of applications in pharmacy, life science, and immunodiagnostics due to their high surface area, ease of synthesis and manipulation, fast separation, good biocompatibility, and recyclable performance. In this work, an innovative and efficient method is developed by in situ reducing and growing Ni(OH)2 for the preparation of dendritic mesoporous nanocomposites of silica@Fe3O4/tannic acid@nickel hydroxide (dSiO2@Fe3O4/TA@Ni(OH)2). The flower-like nanospheres have good magnetic response, large surface area, and high histidine-rich protein (His-protein) purification performance. The dSiO2@Fe3O4/TA@Ni(OH)2 nanospheres were synthesized on the basis of a φ(NaSal/CTAB) of 1/1 and a mass of ferrous chloride tetrahydrate of 0.3 g, resulting in a saturation magnetization value of 48.21 emu/g, which means it can be collected within ∼1 min using a magnetic stand. Also, the BET test showed that the surface area is 92.47 m2/g and the pore size is ∼3.9 nm for dSiO2@Fe3O4/TA@Ni(OH)2 nanocomposites. Notably, the nickel hydroxide with unique flower-like structural features enables the combination of a large number of Ni2+ ions and His-proteins for high performance. The isolation and purification experiments of the synthesized dSiO2@Fe3O4/TA@Ni(OH)2 were performed by separating His-proteins from a matrix composed of bovine hemoglobin (BHb), bovine serum albumin (BSA), and lysozyme (LYZ). The result showed that the nanospheres have a high combination capacity of ∼1880 mg/g in a rapid equilibrium time of 20 min, which was selective for the adsorption of BHb. In addition, the stability and recyclability of BHb are 80% after seven cycles. Furthermore, the nanospheres were also used to isolate His-proteins from fetal bovine serum, proving its utility. Therefore, the strategy of separating and purifying His-proteins using dSiO2@Fe3O4/TA@Ni(OH)2 nanospheres is promising for practical applications.

ABSTRACT

Background: The clinical education of interns on hepatocellular carcinoma (HCC) is both crucial and difficult in China, even if the education reform has advanced constantly over the years. The value of specific 3D printing model (3DPM) in clinical education of HCC is uncertain, and relevant literatures are very few. This study aimed to explore the effects of a patient-specific 3D printing liver model on the clinical education of HCC. Methods: Three laparoscopic hepatectomies were collected. For each case, a 3D virtual reconstruction (3DVR) and 3DPM were created using multi-detector computed tomography (MDCT) data, respectively. A total of 62 interns were randomly assigned to each group (3DPM, 3DVR, and MDCT groups) through a table of random numbers for random grouping. Following lecture-based HCC education, interns in each group selected a corresponding model of HCC. All interns were tested on the hepatic tumor locations, the vessels adjacent to them, surgical planning, and test time using the centesimal system score within 90 min. A questionnaire investigation on the degree of satisfaction, interest, and helpfulness for improving the comprehension ability of liver anatomy and 3D spatial structures was also recorded. The 3DPM group were compared with both 3DVR and MDCT group by theoretical examination scores and questionnaire survey satisfaction to evaluate the effects of 3DPM on the interns' clinical education in HCC. Results: All the interns completed the test and questionnaire. The 3DPM group gained significantly higher scores on the following test contents: indicating the correct tumor location (3DPM vs. 3DVR, MDCT: 36.7±4.8 vs. 33.2±5.8, 26.8±10.0, P=0.03, P<0.01, respectively), accurately identifying the relationship between the tumor and vessels (3DPM vs. 3DVR, MDCT: 37.1±4.6 vs. 31.6±3.7, 30.0±5.8, P<0.01, P<0.01, respectively), and designing appropriate surgical plans (3DPM vs. 3DVR, MDCT: 8±2.7 vs. 4.9±2.7, 5.9±3.8, P<0.01, P=0.04, respectively). The 3DPM group showed a higher degree of satisfaction (86.2%), interest (92.1%), and helpfulness (80.5%) for improving the comprehension ability of liver anatomy and 3D spatial structures. Conclusions: The clinical teaching by utilizing 3DPM can significantly improve the professional theoretical level, strengthen clinical thinking and comprehensive ability, and improve the teaching effects of HCC for medical interns.

ABSTRACT

Liver cancer is one of the most common malignant tumors globally. Not only is it difficult to diagnose, but treatments are scarce and the prognosis is generally poor. Hepatocellular carcinoma (HCC) is the most common type of liver cancer. Aggressive cancer cells, such as those found in HCC, undergo extensive metabolic rewiring as tumorigenesis, the unique feature, ultimately causes adaptation to the neoplastic microenvironment. Intratumoral heterogeneity (ITH) is defined as the presence of distinct genetic features and different phenotypes in the same tumoral region. ITH, a property unique to malignant cancers, results in differences in many different features of tumors, including, but not limited to, tumor growth and resistance to chemotherapy, which in turn is partly responsible for metabolic reprogramming. Moreover, the different metabolic phenotypes might also activate the immune response to varying degrees and help tumor cells escape detection by the immune system. In this review, we summarize the reprogramming of glucose metabolism and tumoral heterogeneity and their associations that occur in HCC, to obtain a better understanding of the mechanisms of HCC oncogenesis.

ABSTRACT

BACKGROUND: Subarachnoid hemorrhage (SAH) is a cerebral hemorrhagic disease with a high disability and fatality rate. Cell pyroptosis is involved in the brain injury following SAH. Here, we explored the effect of HDAC inhibitor SAHA against cell pyroptosis after SAH. METHODS: The rat SAH model was established by endovascular perforation and the rat microglia were treated with 25 µm oxyhemoglobin (OxyHb) for 24 h to mimic SAH model in vitro. Neurological score and brain edema were assessed in rat SAH model. TUNEL staining detected apoptosis. qRT-PCR and western blotting were employed to detect expression levels of miR-340, NEK7 and inflammatory cytokines. ELISA assay determined the secretion of IL-1ß and IL-18 in rat serum and cell supernatant. A lactate dehydrogenase (LDH) kit measured the LDH activity in rat primary microglia. Microglia pyroptosis was detected by flow cytometry. RIP and dual luciferase reporter assays confirmed the binding relationship between miR-340 and NEK7. RESULTS: SAHA alleviated neurological dysfunction, inflammatory injury and microglia pyroptosis in SAH rats. SAHA suppressed LDH release, inflammatory factor expression and pyroptosis in microglia treated with OxyHb. Meanwhile, SAHA increased miR-340 expression and inhibited NEK7 level in vivo and in vitro SAH models. Further, miR-340 directly targeted NEK7 to inhibit the NLRP3 signaling pathway. Knockdown of miR-340 or overexpression of NEK7 reversed the suppressive effects of SAHA on microglia inflammation and pyroptosis. Additionally, knockdown of NEK7 impaired microglia inflammation and pyroptosis induced by miR-340 inhibitor. CONCLUSION: HDAC inhibitor SAHA ameliorates microglia pyroptosis in SAH through triggering miR-340 expression to suppress NEK7 signaling. This novel mechanism provides promise for SAHA in SAH treatment.

ABSTRACT

In this study, TreeAge Pro was used to build a decision tree model for Qilong Capsules in the treatment of ischemic stroke. We compared the economy between Qilong Capsules + conventional therapy vs conventional therapy in the treatment of ischemic stroke to guide the rational allocation of health resources in clinical practice. The cost parameters in the study were obtained from Menet and the relevant literature published recently. Meanwhile, the efficacy parameter [mean reduction in National Institute of Health stroke scale(NIHSS) score after treatment] was employed to evaluate the short-term economic performance of the two therapies based on a prospective real-world cohort study. The time span of simulation was 24 weeks, and the robustness of this study was verified by sensitivity analysis. Qilong Capsules + conventional therapy and conventional therapy had the direct medical costs of CNY 22 546.50, 21 160.50 and the effectiveness of 2.08, 1.59 points, respectively. The incremental cost-effectiveness ratio(ICER) of the two groups was CNY 2 811.36. That is, compared with conventional therapy, Qilong Capsules + conventional therapy in the treatment of ischemic stroke costed CNY 2 811.36 for each additional point reduction in NIHSS score. If the patient is willing to pay more than CNY 2 811.36, Qilong Capsules + conventional therapy is more economical. The result of sensitivity analysis verified that the ICER was robust. Thus, on the basis of the assumption that per capita disposable income in 2020 is the threshold of patients' willingness to pay, Qilong Capsules + conventional therapy is more economical than conventional therapy alone in the treatment of ischemic stroke.

ABSTRACT

The present study systematically sorted out the existing research on Qilong Capsules in the treatment of ischemic stroke with Qi deficiency and blood stasis syndrome and comprehensively evaluated its clinical evidence and value to highlight the advantages and characteristics of products and provide references for the decision-making of national pharmaceutical management departments. Based on the evidence-based medicine, epidemiology, clinical medicine, evidence-based pharmacy, and pharmacoeconomics, the qualitative and quantitative evaluation of "6+1" dimensions of safety, effectiveness, economy, innovation, suitability, and accessibility, as well as characteristics of traditional Chinese medicine(TCM) was performed with multi-criteria decision analysis(MCDA) mo-del using the information, such as public data, literature data, pharmaceutical research, and questionnaire survey, and CSC v2.0 was used to calculate the clinical value of Qilong Capsules. The evaluation results were grade A, B, C, or D. Spontaneous reporting system(SRS) monitoring data, literature reports, clinical trials, and other multi-source safety evidence showed that the main adverse reactions of this drug included dry mouth, nausea, and rash, and no severe adverse reactions was found. The evidence was sufficient with small and controllable known risks, and the safety was grade A. Meta-analysis showed that Qilong Capsules combined with conventional western medicine in the treatment of acute ischemic stroke was superior to the control group in improving neurological deficits, clinical total response rate, patients' activities of daily living, and hemorheological indexes. The level of evidence was high with manifest clinical significance, and the effectiveness was grade A. The results of pharmacoeconomic research showed that Qilong Capsules combined with conventional western medicine in the treatment of ischemic stroke were advantageous in cost-effectiveness as compared with conventional western medicine alone, but the incremental effect was not significant. The quality evaluation results of the economic report were comparatively clear, and the economy was grade B. Aiming at major cerebrovascular diseases in the society and giving full play to the advantages of TCM, Qilong Capsules focused on the inheritance of classics and scientific and technological innovation, and innovation was grade B. The results of the questionnaire survey showed that the technical characteristics and drug application could meet the medication needs of clinical doctors and patients, and the suitability was grade B. The price level of this drug was comparatively high and the affordability was good since the treatment cost accounted for a small proportion of disposable income. The drug accessibility was good with a wide range of drug sales, sufficient production capacity, and sustainable medicinal materials resources, and was grade B. This drug was derived from the classic prescription Buyang Huanwu Decoction with rich experience of human application, which could regulate Qi and blood circulation, and the section of TCM characteristics was grade B. Based on the evidence evaluation results of "6+1" dimensions of Qilong Capsules, the comprehensive evaluation of clinical value was class A. It is suggested that it can be transformed into relevant policy results of basic clinical medication management according to procedures.

ABSTRACT

This study aims to comprehensively summarize articles on the treatment of coronary heart disease angina pectoris with heart blood stasis syndrome(CHD-AP-HBSS) by Guanxin Shutong Capsules(GSC), and comprehensively evaluate the evidence and value of the formula in "6+1" dimensions based on multi-criteria decision analysis(MCDA) model and Guidelines for Management of Comprehensive Clinical Evaluation of Drugs(trial version 2021) with quantitative and qualitative methods, which is expected to highlight the clinical characteristics and advantages of the prescription and serve as a reference for medical and health departments. The dimensions are grade A, B, C, or D. In terms of safety, according to the reports from the spontaneous reporting system of National Center for ADR Monitoring, and literature analysis, GSC mainly results in the adverse reactions of mild or moderate nausea, diarrhea, rash, palpitation, and headache, with favorable prognosis in patients. Nevertheless, severe adverse reactions have been reported after marketing. Thus, additional evidence for its safety should be accumulated, and the current safety is grade B. Meta-analysis proves that GSC in combination with conventional treatment is superior to conventional treatment alone in alleviating AP and symptoms indicated by electrocardiogram(ECG). Therefore, the effectiveness of the medicine is grade A. As for the pharmacoeconomic value, based on the assumption that the per capita disposable income in 2020 is the willingness-to-pay threshold, it is more economical for CHD-AP patients to use GSC combined with conventional treatment than conventional treatment alone. However, as the currently available clinical parameters fail to support the difference in indirect cost between the two groups, the accuracy in the cost of intervention plan needs to be further improved. Therefore, the economy of the prescription is grade B. GSC has been awarded 13 national invention patents and 1 utility model patent, and won a lot of national and provincial patent awards, marking the enterprise service awareness and innovativeness. As a result, it is grade A in aspect of innovation. A questionnaire on the suitability of GSC suggests that publicity and promotion influence patients' choice and thus additional efforts should be made in this aspect. The suitability of this formula is grade B. Both rural and urban residents can afford the medicine for the whole course and the price is close to that of similar Chinese patent medicines. In addition, it is accessible regardless of season and place, so accessibility is grade A. As a Mongolian empirical formula destined to treat heart stabbing pain, it has the effects of activating blood and resolving stasis, dredging channels and activating collaterals, and moving Qi to relieve pain, and boasts the empirical evidence of more than 2 000 human cases. With prominent characteristics of traditional Chinese medicine, it is grade B. Based on the MCDA model and CSC v2.0, GSC is comprehensively class A in the treatment of CHD-AP-HBSS. The result can serve as a reference for basic clinical medication management.

ABSTRACT

This study systematically sorted out the evidence data of the safety, effectiveness, economy, innovation, suitability, accessibility, and characteristics of traditional Chinese medicine(TCM) of Reyanning Mixture in the treatment of acute upper respiratory tract infection(heat-toxin attacking lung syndrome) with the qualitative and quantitative evaluation methods adopted. Based on evidence-based medicine, epidemiology, clinical medicine, evidence-based pharmacy, pharmacoeconomics, and health technology evalua-tion(HTA), the clinical value of Reyanning Mixture was evaluated using multi-criteria decision analysis(MCDA) model, Chinese patent medicine clinical evidence, and value evaluation software(CSC v2.0). The SRS monitoring data, Meta-analysis, and other safety evidence showed that the main adverse reactions of Reyanning Mixture were nausea, diarrhea, and rash, and no serious adverse reactions were found. The pharmacovigilance system was sound, and the system was perfect. There was no recall, notification, or interview for unqualified products. Based on the existing research, the evidence was sufficient, and the risk was controllable. Hence, its safety was grade A. Meta-analysis showed that in the treatment of acute upper respiratory tract infection, Reyanning Mixture combined with Amoxicillin Capsules was better than Amoxicillin Capsules alone in shortening the complete fever relief time and improving the cure rate. Besides, it was superior to Shuanghuanglian Granules in shortening the complete fever relief time, cough relief time, nasal congestion relief time, and pharyngeal congestion relief time. The Meta-analysis was conducted based on AMSTAR standard, and its ove-rall quality was proved good. The evidence quality in GRADE system evaluation was medium and low. The quality of evidence was medium, and the clinical value was obvious. Hence, its effectiveness was grade A. The results of pharmacoeconomic research showed that compared with Amoxicillin Capsules, Reyanning Mixture alone or in combination with Amoxicillin Capsules had cost-effectiveness advantages in the treatment of acute upper respiratory tract infection, and the results were stable in sensitivity analysis. According to the CASP economic evaluation checklist, the research problems were clear and the results were reliable. As revealed by the comprehensive evaluation, the evidence quality was sufficient and the result was clear. Its economy was grade B. Reyanning Mixture had multiple therapeutic targets like anti-virus, anti-bacteria, antipyresis, and anti-cough, with good clinical innovation. There were many innovative initiatives in ensuring drug supply, especially at the grass roots, drug safety, and effectiveness, and also multiple innovative contributions to production technology, quality control, scientific and technological research and development, and enterprise management and marketing. Therefore, its innovation was grade B. The dosage form of Reyanning was mixture, which made it convenient for storage and transportation. The usage was easy to be mastered and accepted by doctors and nurses, exhibiting good suitability for clinicians, nurses, pharmacists, and patients who received this drug and basically meeting the needs of clinical medication.

ABSTRACT

This clinical value-oriented comprehensive evaluation of drugs was carried out in accordance with Guidelines for Management of Comprehensive Clinical Evaluation of Drugs(trial version 2021), with the qualitative and quantitative evaluation methods adopted. Based on the evidence-based medicine, epidemiology, clinical medicine, pharmacoeconomics, mathematical statistics, and health technology evaluation(HTA), the clinical value of Ginkgolide Injection was evaluated from the "6+1" dimension by giving weight to the criterion level and index level and calculating with multi-criteria decision analysis(MCDA) model and CSC v2.0. After entering the market, Ginkgolide Injection has been subjected to phase Ⅳ clinical trial, spontaneous reporting system(SRS)-based data monitoring, systematic review and Meta-analysis, acute toxicity and long-term toxicity assays, active monitoring, and RCTs, and the evidence of safety was sufficient. The results of active monitoring showed that the incidence of adverse reactions was 0.09%(rare), mainly manifested as flushing, dizziness, rash, nausea, and vomiting. According to the nested case-control study, the adverse reactions of this drug had nothing to do with the product batch, implying that the drug quality was controllable. The adverse reactions mainly resulted from the pharmacodynamic reactions. Because the drug was effective in resisting platelet aggregation, the resulting adverse reactions such as flushing, dizziness, headache, and phlebitis were caused by vasodilation. Skin rash and gastrointestinal symptoms were mainly attributed to the patients' sensitivity to drugs and their own allergic constitution. According to the sufficiency of evidence and the incidence of adverse reactions in the safety research, the safety of Ginkgolide Injection was grade A. The results of Meta-analysis showed that Ginkgolide Injection combined with conventional western medicine was superior to conventional western medicine in improving the clinical effective rate, neurological function score, and activity of daily living score of patients with cerebral infarction. The validity evidence was evaluated according to the PICO principle to be high. According to the GREAD evaluation principle, the quality of such evidence as clinical effective rate, National Institute of Health stroke scale(NIHSS), and Barthel Index(BI) was evaluated, and the results demonstrated that the evidence quality of clinical effective rate and activity of daily living score was medium. The effectiveness of Ginkgolide Injection was grade A. According to the economic report of Ginkgolide Injection, it had short-term and long-term pharmacoeconomic advantages in the treatment of ischemic stroke, and the economic evidence value was good. According to the CASP economic evaluation checklist, the overall quality evaluation results of the economic report are basically clear. To be specific, the economic evidence quality was high. Based on the comprehensive economic evidence quality and economic value, the economy of this drug was grade A. The innovation of this product was evaluated from three aspects: clinical innovation, enterprise service system innovation, and industrial innovation. Ginkgolide Injection could be used 24 h after intravenous thrombolysis for improving patients' neurological function without increasing bleeding, indicating its important clinical innovation. There were many innovations in ensuring drug supply, especially at the grass roots, drug safety, effectiveness, and reasonable price, which has provided reference for establishing enterprise philosophy, managing drug resources, developing process and technology, and determining enterprise management and marketing. Therefore, its innovation was grade A. The drug had no special medication plan in use, exhibiting good suitability for doctors, nurses, and patients. The suitability was grade B. Compared with similar drugs, its price was at a medium level, meaning good affordability, sufficient production capacity, and easy accessibility. Its accessibility was therefore grade B. This drug belonged to Chinese medicinal injection. The large-sample real-world research revealed rich human use experience, so it was grade C for the traditional Chinese medicine characteristic. According to the comprehensive evaluation, the clinical value of Ginkgolide Injection in the treatment of cerebral infarction fell into class A.

ABSTRACT

An exploration of the underlying mechanisms is necessary to improve nerve myelin-forming cell Schwann cell (SC) differentiation from adipose-derived stem cells (ADSCs). Primary rat ADSCs were isolated and characterised for cell surface markers using flow cytometry analysis. After treatment with a mixture of glial growth factors, ADSCs were induced to differentiate and subsequently identified by immunofluorescence staining and western blotting. A miRNA microarray analysis was performed to explore the genes and signalling pathways regulating ADSC differentiation into SCs. ELISAs were conducted to measure the expression of neurotrophic factors and changes in the level of nerve cell adhesion factor. Dual luciferase reporter assays and RIP assays were performed to explore the potential mechanism of miR-21-5p in ADSC differentiation. The isolated ADSCs were positive for CD29 and CD44 but negative for CD49. After induction with specific cytokines, the differentiated ADSCs presented a spindle-like morphology similar to SCs and expressed S100. RNA-sequencing analyses revealed that 9821 mRNAs of protein-coding genes and 175 miRNAs were differentially expressed in differentiated SC-like cells compared to primary cultures of ADSCs. KEGG and Gene Ontology analyses revealed that the involvement of the Notch signalling pathway and miRNA negative regulation may be associated with the differentiation of ADSCs into SCs. Treatment with a Notch inhibitor promoted the differentiation of ADSCs. Furthermore, mechanistic studies showed that Jag1 bound to miR-21-5p and upregulated its target gene Jag1, thus affecting ADSC differentiation. These results revealed the mechanism underlying the important roles of miRNAs and the Notch signalling pathway in the differentiation of SCs from ADSCs, enabling potential therapeutic applications of ADSCs in peripheral nerve regeneration in the future.
