RESUMO

BACKGROUND: Hepatocellular carcinoma with peritoneal metastasis (HCC-PM) has a poor outlook. Traditional treatments have limited effect on survival. The safety and efficacy of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) have been shown in other peritoneal cancers. This study evaluates the role of CRS + HIPEC in HCC-PM. METHODS: A retrospective analysis of HCC-PM patients treated with CRS + HIPEC at Beijing Shijitan Hospital from March 2017 to December 2023 was conducted, assessing clinical features, severe adverse events (SAEs), and overall survival (OS) rates. RESULTS: The study population comprised 10 HCC-PM patients who underwent CRS + HIPEC. The median peritoneal cancer index (PCI) was 25, and complete cytoreduction (CC0 ~ 1) was achieved in half of the patients. Three patients experienced SAEs within 30 days postoperatively. The 1-year, 3-year, and 5-year OS rates were recorded as 89.0%, 89.0%, and 21.0% respectively, with a median OS1 of 107.8 months and OS2 of 49.9 months. The median progression-free survival (PFS) was 5.0 months. CONCLUSION: The application of CRS + HIPEC offers significant benefits to patients with HCC-PM. A selected group of patients may achieve prolonged PFS. Incorporating CRS + HIPEC into the treatment paradigm can thus be considered a strategic therapeutic option for patients with HCC-PM.

RESUMO

The authentic traditional Chinese medicines (TCMs) including Angelicae Sinensis Radix (ASR) are the representative of high-quality herbals in China. However, ASR from authentic region being adulterated or counterfeited is frequently occurring, and there is still a lack of rapid quality evaluation methods for identifying the authentic ASR. In this study, the color features of ASR were firstly characterized. The results showed that the authentic ASR cannot be fully identified by color characteristics. Then near-infrared (NIR) spectroscopy combined with Bayesian optimized long short-term memory (BO-LSTM) was used to evaluate the quality of ASR, and the performance of BO-LSTM with common classification and regression algorithms was compared. The results revealed that following the pretreatment of NIR spectra, the optimal NIR spectra combined with BO-LSTM not only successfully distinguished authentic, non-authentic, and adulterated ASR with 100 % accuracy, but also accurately predicted the adulteration concentration of authentic ASR (R2 > 0.99). Moreover, BO-LSTM demonstrated excellent performance in classification and regression compared with common algorithms (ANN, SVM, PLSR, etc.). Overall, the proposed strategy could quickly and accurately evaluate the quality of ASR, which provided a reference for other TCMs.

RESUMO

This study aimed to explore the differences in raw Angelica Sinensis (RAS), wine washing AS (WAS), and wine stir-frying AS (WSAS). The results showed there were differences among the three AS in color and aroma, and 34 aroma compounds were identified. The content determination results revealed the ferulic acid and Z-ligustilide levels of RAS decreased after processing, and those in WAS were higher than in WSAS. Furthermore, 85 representative common components and 37 unique components were tentatively identified in three AS. Finally, the free radical scavenging assay results indicated the antioxidant capacity of RAS was reduced after processing, and the antioxidant capacity of WAS was better than WSAS. Collectively, the RAS undergoes significant changes in color, aromas, components, and antioxidant ability after processing, and the different processing methods also result in significant differences between WAS and WSAS.

RESUMO

A coordinated interaction between osteogenesis and the osteoimmune microenvironment plays a vital role in regulating bone healing. However, disturbances in the pro- and anti-inflammatory balance hinder the therapeutic advantages of biomaterials. In this study, a novel composite hydrogel was successfully fabricated using graphene oxide (GO)-loaded processed pyritum (PP) in combination with poly(ethylene glycol) diacrylate (PEGDA) and carboxymethyl chitosan (CMC). Subsequently, the immunomodulatory effects and bone regenerative potential of PP/GO@PEGDA/CMC were investigated. The results demonstrated that the PP/GO@PEGDA/CMC hydrogel possessed excellent mechanical properties, swelling capacity, and stability. Moreover, PP/GO@PEGDA/CMC prominently promoted M2 polarization and increased the levels of anti-inflammatory factors (interleukin (IL)-4, IL-10, and transforming growth factor-ß). These beneficial effects facilitated the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells in vitro. Additionally, the in vivo results further verified that the implantation of PP/GO@PEGDA/CMC markedly reduced local inflammation while enhancing bone regeneration at 8 weeks post-implantation. Therefore, the results of this study provide potential therapeutic strategies for bone tissue repair and regeneration by modulating the immune microenvironment.

RESUMO

The real-time cell-based assay(RTCA) was used to establish the bioelectrical sensing model of Compound Danshen Dripping Pills with rat cardiomyocytes(H9 c2). The time/dose-dependent cell response profiles(TCRPs) of in vitro dissolution and absorption of the pills were determined to establish the continuous dynamic dissolution and absorption kinetic models. Thereby, the cell index(CI)-based dissolution and absorption kinetic curves and kinetic models of Compound Danshen Dripping Pills were obtained. The optimal dissolution kinetic model was Weibull model. The similarity factors f_2 of dissolution curves were greater than 50 and the correlation coefficients of absorption curves were larger than 0.95. With the experiment about the efficacy on mice, percentages of the bleeding time of mice administrated with Compound Danshen Dripping Pills were calculated, and there was a correlation among dissolution, absorption, and efficacy curves(r > 0.9). RTCA is applicable to the study of the dissolution and absorption kinetics of solid compound Chinese medicine preparations. Thus, it is an innovative and feasible method to evaluate the quality and batch consistency of compound Chinese medicine preparations.

RESUMO

This study explores the dissolution mechanism and absorption process of compound Danshen tablets (CDTs) and compound Danshen capsules (CDCs) in vitro. Taking the cell index as the evaluation index of dissolution and absorption of multi-component solid preparations of CDTs and CDCs, it breaks through the idea of traditional research. We used real-time cell-based assay (RTCA) to provide a new idea and method for the consistency evaluation of traditional Chinese medicine (TCM) compound preparations. The drug dissolution and absorption simulation system (DDASS) was established to obtain the dissolution and absorption samples of compound Danshen solid preparations at different time points. The cell index (CI) of the sample to H9C2 cells was detected by RTCA technology, and the dissolution and absorption percentage were calculated based on this index to obtain the dissolution and absorption kinetics model. Meanwhile, one batch of tablets and one batch of capsules (batch numbers ZKC1816 and 202101001) were selected to conduct the overall animal pharmacodynamic experiment to verify the feasibility of drug effect evaluation with cell index as an indicator. The best fitting model of dissolution curves of each batch of CDTs and CDCs is the Weibull model. There was a good correlation (r > 0.86) between the dissolution-absorption-pharmacodynamic curve. Based on RTCA technology, we have established the comprehensive evaluation method for cell biology of compound Danshen solid preparations in line with the overall concept of TCM and a synchronous evaluation system of dissolution and absorption in vitro of new TCM compound solid preparations.

RESUMO

Although cancer has seriously threatened people's health, it is also identified by the World Health Organization as a controllable, treatable and even curable chronic disease. Traditional Chinese medicine (TCM) has been extensively used to treat cancer due to its multiple targets, minimum side effects and potent therapeutic effects, and thus plays an important role in all stages of tumor therapy. With the continuous progress in cancer treatment, the overall efficacy of cancer therapy has been significantly improved, and the survival time of patients has been dramatically prolonged. In recent years, a series of advanced technologies, including nanotechnology, gene editing technology, real-time cell-based assay (RTCA) technology, and flow cytometry analysis technology, have been developed and applied to study TCM for cancer therapy, which efficiently improve the medicinal value of TCM and accelerate the research progress of TCM in cancer therapy. Therefore, the applications of these advanced technologies in TCM for cancer therapy are summarized in this review. We hope this review will provide a good guidance for TCM in cancer therapy.

RESUMO

Based on UPLC characteristic chromatogram and quantitative analysis of multi-components by single marker(QAMS), the content of seven types of ginsenosides in Ginseng Radix et Rhizoma was simultaneously determined, and the quality of Ginseng Radix et Rhizoma was evaluated by the principal component analysis(PCA). The chromatographic separation was performed on the Acquity UPLC BEH C_(18) column(2.1 mm×100 mm, 1.7 µm) with the mobile phase of acetonitrile-water for gradient elution at the flow rate of 0.3 mL·min~(-1), the column temperature of 30 ℃, the detection wavelength of 203 nm, and the injection volume of 2 µL. The UPLC chromatogram was established with 19 batches of Ginseng Radix et Rhizoma samples from three producing areas by Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(version 2012). Thirteen characteristic peaks were determined and seven components were identified. SPSS 26.0 was used to conduct PCA on the characteristic peak areas. With the peak of ginsenoside Rb_1 as reference peak S, ginsenoside Rb_1 showed good durability of relative correction factor as compared with other ginsenosides. The QAMS method for the determination of seven ginsenosides in Ginseng Radix et Rhizoma was established. There was no significant difference in results between the QAMS method and the external standard method. As revealed by the results of PCA and the determination of the total content of seven ginsenosides, the four batches of Ginseng Radix et Rhizoma numbered S19, S18, S1, and S2 were of superior quality. The characteristic chromatogram and QAMS method for the determination of seven ginsenosides in this study were convenient and accurate, which greatly shortened the analysis time and improved the analysis efficiency. The findings of this study are expected to provide a basis for the overall quality evaluation of Ginseng Radix et Rhizoma.

RESUMO

The present study explored the mechanism of Qingwei Powder(QP) in the treatment of periodontitis based on chromatography-mass spectrometry and network pharmacology-molecular docking techniques. UPLC-Q-TOF-MS and GC-MS were used to identify the chemical constituents of QP. The active components and targets were screened out through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and their targets were predicted using SwissTargetPrediction. Targets related to periodontitis were obtained from GeneCards, OMIM, and DisGeNET. Venn diagram was constructed using Venny 2.1 to obtain the intersection targets. Cytoscape 3.7.2 was used to construct the "chemical component-target-disease" network. The targets were analyzed for Gene Ontology(GO) function and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment by clusterProfiler R, and the "chemical component-target-pathway" network was constructed. The binding activity of the active components to the target proteins was verified by molecular docking. A total of 189 chemical components were obtained by UPLC-Q-TOF-MS and GC-MS, including 39 active components with 180 potential targets related to periodontitis. Target enrichment analysis of the active components yielded 92 KEGG pathways. Twenty KEGG pathways, 34 active components, and 99 targets were involved in the "chemical component-target-pathway" network. Molecular docking verified a good binding ability of the key targets to the key compounds. This study preliminarily indicates that QP is effective in treating periodontitis through multiple components, multiple targets, and multiple pathways, which reflects the complex system of Chinese medicine. This study provides the theoretical foundation for the subsequent research on the material basis and key quality attributes of QP.

RESUMO

Essential oils(EOs) from Chinese medicinals, which can be used as adjuvants and exert certain therapeutic effect, are directly used in Chinese medicine formulas. Conventional research strategy for EOs from Chinese medicinals is to compare the efficacy of the prescriptions before and after the addition of EOs, and the penetration-enhancing mechanisms of EOs remain unclear. In modern research on EOs from Chinese medicinals, the method for studying chemical penetration enhancers is often used, which fails to reflect the overall efficacy of EOs. This study clarified the property regularity of EOs from Chinese medicinals as transdermal penetration enhancers, and thereby proposed a research model which integrated the medicinal and adjuvant properties of EOs from Chinese medicinals via "component-delivery-effect" characterization route. The core concept is that constituents of EOs from Chinese medicinals and their delivery process play a key role in their external application. This research model is expected to serve as a reference for further research on EOs from Chinese medicinals for transdermal application.

RESUMO

To clarify the key quality attributes of substance benchmarks in Danggui Buxue Decoction(DBD), this study prepared 21 batches of DBD substance benchmarks, and established two methods for detecting their fingerprints, followed by the identification of peak attribution and similarity range as well as the determination of extract and transfer rate ranges and contents of index components ferulic acid, calycosin-7-O-ß-D-glucoside, and astragaloside Ⅳ. The mass fractions and transfer rates of DBD substance benchmarks from different batches were calculated as follows: ferulic acid(index component in Angelicae Sinensis Radix): 0.037%-0.084% and 31.41%-98.88%; astragaloside Ⅳ(index component in Astragali Radix): 0.021%-0.059% and 32.18%-118.57%; calycosin-7-O-ß-D-glucoside: 0.002%-0.023% and 11.51%-45.65%, with the extract rate being 18.4%-36.1%. The similarity of fingerprints among 21 batches of DBD substance benchmarks was all higher than 0.9. The quality control method for DBD substance benchmarks was preliminarily established based on the HPLC fingerprint analysis and index component determination, which has provided a basis for the subsequent development of DBD and the quality control of novel related preparations.

RESUMO

BACKGROUND: Breast cancer (BC) has the highest morbidity and the fifth-highest mortality rate among women in China. Peritoneal metastases from BC are rare, and presently, there are no guidelines or international consensus on its treatment. Patients with a prognosis of peritoneal carcinomatosis (PC) have poorer survival rates than patients with other regional metastases from BC. METHODS: Four BC PC patients, who had undergone cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC), participated in this study. Clinicopathologic characteristics and overall survival (OS) data were collected and analyzed. RESULTS: Patients' average age when they underwent CRS + HIPEC was 59.8 years. The average time of CRS + HIPEC was 8.8 h. The median number of resected organ areas was 7. Following CRS + HIPEC, each of the 4 patients survived for 31, 28, 16 and 52 months, respectively. There were no serious adverse events during the perioperative period. CONCLUSIONS: The study examined the detailed process of CRS + HIPEC and found that patients with BC PC may benefit from this treatment. The 4 cases provided evidence that the integrated therapy of CRS + HIPEC is a promising strategy that could improve outcomes for BC PC patients. Further, no serious adverse events (SAEs) occurred during the CRS + HIPEC perioperative period.

RESUMO

Ethosomes are widely applied as the carriers for the transdermal delivery of hydrophobic and hydrophilic drugs. Herein, curcumin-loaded ethosomes (CE) with different phospholipid composition were formulated and thoroughly compared. A significant interaction between the unsaturated phosphatidylcholine (PC) and saturated hydrogenated phosphatidylcholine (HPC) was found by molecular simulation and differential scanning calorimetry (DSC), which led to the reduction of PC peroxidation with the presence of HPC. Subsequently, the composite phospholipid ethosomes containing curcumin were prepared for the first time to evaluate their properties in comparison with the conventional ethosomes composed of PC (CE-P) or HPC (CE-H). CE with PC/HPC ratio of 1:1 (CE-P1H1) with the best vesicle stability and flexibility significantly decreased the uptake by HaCaT cells compared to CE-H and free curcumin, indicating reduced skin cell toxicity. Compared with free curcumin, CE-P1H1 had the highest transdermal efficiency (p < 0.001), followed by CE-P (p < 0.05), partly due to the fact that CE-P1H1 could disturb lipid domain of stratum corneum (SC). Moreover, CE-P1H1 was found to promote curcumin for deep penetration of the skin via the hair follicles route. Our study has shown that using composite phospholipid ethosomes as lipid vesicular carriers could enhance transdermal penetration of drugs and increase in the vesicle stability.

RESUMO

OBJECTIVE: The role of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in gastric cancer with peritoneal metastasis (GCPM) is still controversial, mainly due to the limited survival benefit and uncertain patient selection. This study aims to construct a selecting strategy in GCPM for CRS + HIPEC. METHODS: From a prospective established database, 125 patients were enrolled. All these patients were pathologically confirmed as GCPM and treated with CRS + HIPEC with or without preoperative or postoperative chemotherapy. The clinical documents and follow-up results were collected and analyzed with the primary endpoint of overall survival (OS) and the secondary endpoint of perioperative serious adverse events (SAEs). RESULTS: The median OS of 125 GCPM patients treated with CRS + HIPEC was 10.7 months, with 1-, 2-, 3-, and 5-year survival rates of 43.8%, 24.7%, 18.6%, and 15.7%, respectively. The multivariate analysis identified completeness of cytoreduction (CC), SAEs, HIPEC drugs, and adjuvant chemotherapy as independent prognostic factors on OS. The median OS was 30.0 (95%CI: 16.8-43.3) months in CC-0 group, significantly better than 7.3 (95%CI: 5.8-8.8) months in CC1-3 group (P < 0.001). The median OS showed no significant difference among CC-1 (8.5, 95%CI: 6.7-10.2, months), CC-2 (5.6, 95%CI: 3.0-8.2, months) and CC-3 (6.5, 95%CI: 5.2-7.7, months) groups (P > 0.05 for all pairwise comparations). The nomogram based on peritoneal metastasis timing, preoperative tumor marker (TM), and peritoneal cancer index (PCI), with AUC of 0.985, showed a good accuracy and consistency between actual observation and prediction of the probability of complete CRS. The cutoffs of PCI were 16 for synchronous GCPM with normal TM, 12 for synchronous GCPM with abnormal TM, 10 for metachronous GCPM with normal TM, and 5 for metachronous GCPM with abnormal TM, setting the probability to achieve complete CRS as 50%. CONCLUSIONS: Only complete CRS + HIPEC (CC-0) could improve survival for high selected GCPM patients with acceptable safety. An incomplete CRS (CC1-3) should be avoided for GCPM patients. Synchronous GCPM with PCI ≤16 and normal TM, synchronous GCPM with PCI ≤12 and abnormal TM, metachronous GCPM with PCI ≤10 and normal TM, or metachronous GCPM with PCI ≤5 and abnormal TM maybe potential indications for complete CRS + HIPEC treatment.

RESUMO

Background: The pathogenesis of inflammatory bowel disease (IBD) is linked to an intricate association of environmental, microbial, and host-related factors. Polysaccharide affects host immunity by regulating the composition and metabolism of gut microbiota is the common mechanism of disease resistance. However, the efficacy and mechanism of Schisandra chinensis polysaccharide (SCP) in the treatment of inflammatory bowel disease have not been studied. Objective: To explore the effect and mechanism of SCP on dextran sodium sulfate (DSS) - induced ulcerative colitis (UC) in mice. Materials/Methods: In this study, we established a mouse model of UC, and used SCP for treatment intervention. The biochemical indexes related to inflammation were determined by ELISA kit, and the therapeutic effect of SCP on UC was clarified. Then, 16S rDNA sequencing was used to study the effect of SCP on the composition and diversity of gut microbiota. At the same time, GC-MS was used to determine the content of short chain fatty acids in intestinal contents. Finally, the relationship among gut microbiota, short chain fatty acids and inflammatory factors was analyzed, and to comprehensively explain the effect and mechanism of SCP on UC. Results: The results showed that SCP could significantly improve the physiological state of UC mice and regulate the level of inflammatory factors to normal levels. Meanwhile, SCP could significantly regulate the imbalance of gut microbiota and increase the content of SCFAs. In addition, the results of the correlation between gut microbiota and SCFAs showed that butyric acid, isobutyric acid and valeric acid had the highest correlation with gut microbiota. Conclusion: In conclusion, this research showed that SCP can inhibit inflammatory bowel disease by regulating the composition and metabolism of gut microbiota, and indicating that SCP may be used as adjuvant therapy for IBD patients.

RESUMO

RATIONALE: Signet ring cell carcinoma of the stomach is prone to relapse and metastasis after traditional surgical treatment, and the prognosis is also poor. We improved the concept of treatment and conducted cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) combined with intraperitoneal (IP) and intravenous (IV) chemotherapy for a gastric signet-cell carcinoma patient. PATIENT CONCERNS: A 65-year-old male patient with complaint of intermittent hematemesis for over 10 days was referred to our hospital for treatment. The patient developed hematemesis of 800 mL without obvious causes on May 27, 2015, accompanied by dizziness and amaurosis fugax. After the bleeding was stopped with medicinal treatment, diagnostic gastroscopy revealed an ulcer at the less curvature of the stomach, with biopsy pathology diagnosis as severe atypical hyperplasia, which was confirmed to be poorly differentiated adenocarcinoma by a second biopsy. In past medical history, the patient had 5 coronary stents implanted because of coronary atherosclerotic heart disease 3 years ago. DIAGNOSIS: Gastric cancer (cT4NxMx) according to the patient's history and biopsy pathology. INTERVENTIONS: the patient was treated surgery-based multidisciplinary treatments integrating CRS + HIPEC and IP + IV adjuvant chemotherapy. The CRS was curative distal gastrectomy with D2 lymphadenectomy, and HIPEC was cisplatin 120 mg plus mitomycin C 30 mg at 43 °C, for 60 minutes. Final pathological diagnosis of after surgery was: poorly differentiate adenocarcinoma with signet-ring cells, with invasion beyond the serosal layer and into the duodenum, 10/23 lymph nodes positive, nerve invasion, vascular tumor thrombi, Borrmann type IV, Lauren type diffuse. TNM stage was pT4aN3M0, IIIC. After operation, the patient received 6 courses of IV chemotherapy with oxaliplatin and 5-fluorouracil/Tegafur Gimeracil Oteracil Potassium capsules, and IP chemotherapy with docetaxel and carboplatin. OUTCOMES: Regular follow-up till July 20, 2020, revealed that the patient has a disease-free survival of over 61+ months. LESSONS: CRS + HIPEC combined with IP + IV chemotherapy achieved long-term disease-free survival for this patient with gastric signet-ring cell carcinoma and deserve further study. This new treatment modality deserves appropriate consideration in routine clinical practice for patients with advanced gastric cancer.

RESUMO

As an outstanding representative of traditional Chinese medicine( TCM),ancient classical prescriptions carry the profound accumulation of the splendid civilization of Chinese medicine for thousands of years. It is the best part of the great treasure-house of Chinese medicine after thousands of years' training of TCM theory. It condenses the wisdom of all generations of doctors,and as the summary of clinical experience,it is the most brilliant pearl in the treasure house of TCM. The in-depth research and development of ancient classic prescriptions is a golden key to excavate the treasure house of TCM,which not only conforms to the development trend of TCM industry,but also brings unprecedented opportunities and challenges for the inheritance and innovation of contemporary Chinese herbal compound preparations. However,as a " new member" in the national drug research and development system,classic prescriptions have no specific implementation rules although the guidance is given by macro policies,and there is no successful case of research and development according to the registration requirements. Therefore,unified consensus and standards have not yet been formed for some key issues in the process of the development of the classic prescriptions,and much work is still in the exploration stage,so it is necessary to conduct in-depth research and discussion on these issues.

RESUMO

In order to determine the quality evaluation method for standard decoction of Coptidis Rhizoma,15 batches of standard decoction of Coptidis Rhizoma were prepared by using standardized process. Parameters such as traits,p H value,indicative component content,fingerprint similarity,composition transfer rate and dry extract rate were selected as the indexes for quality evaluation. Similarity evaluation and cluster analysis were performed for HPLC fingerprint of standard decoction,and mathematical model was used to study the correlation between dry extract rate,berberine content,berberine transfer rate in standard decoction and berberine content in decoction pieces. The results showed that the similarity of fingerprints was greater than 0. 99 for these 15 batches of standard decoctions of Coptidis Rhizoma. In cluster analysis,the standard decoctions of Coptidis Rhizoma from 4 producing areas were classified into 3 categories,consistent with the content determination results,indicating that there were quality differences among different producing areas.R2 in three linear regression mathematical models established was all greater than 0. 9,with significant difference. The validation of three batches of data showed that the models had good accuracy. Therefore,this model can be used to predict the quality of standard decoction prepared from different Coptidis Rhizoma pieces. In the standard decoction process established in this study,the integrity of the traditional process was greatly preserved,and the established quality evaluation method could be used to comprehensively examine the quality of the standard decoction,which can provide a demonstration for the related research of water extraction preparation containing Coptidis Rhizoma pieces.

RESUMO

Microfluidic technology (MF) has improved the formulation of nanoparticles (NPs) by achieving uniform particle size distribution, controllable particle size, and consistency. Moreover, because liquid mixing can be precisely controlled in the pores of the microfluidic chip, maintaining high mixing efficiency, MF exerts higher of NP encapsulation efficiency (EE) than conventional methods. MF-NPs-cabazitaxel (CTX) particles (MF-NPs-CTX) were first prepared by encapsulating CTX according to MF. Folate (FA)- Polyethylene glycol (PEG)-NPs-CTX particles (FA-PEG-NPs-CTX) were formulated by connecting FA to MF-NPs-CTX to endow NPs with targeted delivery capability. Accordingly, the mean particle size of FA-PEG-NPs-CTX increased by approximately 25 nm, as compared with MF-NPs-CTX. Upon morphological observation of FA-PEG-NPs-CTX and MF-NPs-CTX by transmission electron microscopy (TEM), all NPs were spherical and particle size distribution was uniform. Moreover, the increased delivery efficiency of CTX in vitro and its strong tumor inhibition in vivo indicated that FA-PEG-NPs-CTX had a powerful tumor-suppressive effect both in vitro and in vivo. In vivo imaging and pharmacokinetic data confirmed that FA-PEG-NPs-CTX had good drug delivery efficiency. Taken together, FA-PEG-NPs-CTX particles prepared using MF showed high efficient and targeted drug delivery and may have a considerable driving effect on the clinical application of targeting albumin NPs.

RESUMO

The application of nanotechnology to traditional Chinese medicine (TCM) enabled the development of Chinese medicine in the international society. The pharmacodynamics of TCM is not only depending on its chemical constituents but also related to its physical state such as particle size. Indeed, there is some new pesticide effect that appeared when the medicine was being made into nanophase. The application of nanotechnology to TCM can expand the use of a range of Chinese medicinal materials. In this review, we introduce the concept of nanometer TCM. We also review the preparation methods, advantages, and development tendency of Nano-TCM; furthermore, we analyze the problems in the process of development of Nano-TCM and put forward varies possible solutions to solve this problems, thereby providing new thought for the development of Nano-TCM.
