Abstract
Integrated traditional Chinese medicine (TCM) and Western medicine (WM) is a new medical science grounded in the knowledge bases of both TCM and WM, which then forms a unique modern medical system in China. Integrated TCM and WM has a long history in China, and has made important achievements in the process of clinical diagnosis and treatment. However, the methodological defects in currently published clinical practice guidelines limit its development. The organic integration of TCM and WM is a deeper integration of TCM and WM. To realize the progression of "integration" to "organic integration", a targeted and standardized guideline development methodology is needed. Therefore, the purpose of this study is to establish a standardized development procedure for clinical practice guidelines for the organic integration of TCM and WM to promote the systematic integration of TCM and WM research results into clinical practice guidelines in order to achieve optimal results as the whole is greater than the sum of the parts.

Abstract
Objective: To understand the distribution characteristics of age of Alzheimer's disease (AD) onset and influencing factors. Methods: Based on the follow-up data of Alzheimer's Disease Neuroimaging Initiative from 2005 to 2022, participants with normal cognition (CN) or mild cognitive impairment (MCI) at baseline survey, and those with progression to AD during follow-up period were selected as study subjects. Univariate analysis and multiple linear regression analysis were performed to explore the associations of gender, race, number of ApoE ε4 genes carried, family history, years of education and marital status with the age of AD onset. Results: A total of 405 participants, with an average age of (74.0±6.9) years at baseline survey, progressed to AD during follow up period. The age of AD onset was (76.6±7.5) years, and age of onset in men was about 1.9 years later than women. Multiple linear regression analysis showed that for each increase in ApoE ε4 gene number, the age of AD onset was about 0.344 years earlier. The age of AD onset was 4.007 years earlier for those with MCI at baseline survey compared with those with CN. Years of education were not significantly associated with the age of onset of AD (P>0.05). Conclusion: Those who carry ApoE ε4 gene, and have MCI at baseline survey might have earlier age of AD onset.

Abstract
Objective: To investigate the mechanism of VPS26 effect on osteogenesis and adipogenesis differentiation of rat bone marrow mesenchymal stem cells (BMSC) in high fat environment, and to explore the effect of VPS26 on implants osseointegration of high fat rats and ectopic osteogenesis in nude mice. Methods: BMSC were cultured under normal osteogenic induction (osteogenic group) and high-fat osteogenic induction (high-fat group).High-fat group was transfected with VPS26 enhancer and inhibitor, and the expression levels of osteogenesis related genes and adipogenesis related genes were examined. Osteogenesis and adipogenesis of BMSC were detected by alkaline phosphatase (ALP) staining and oil red O staining after 7 and 14 days of induction.In osteogenic group,the binding of VPS26 to β-catenin was detected by immunofluorescence staining and immunoprecipitation, and dual luciferase reporter assay (TOP Flash) was used to analyze the TOP/FOP ratio. Eighteen male 12-week hyperlipidemic Wista rats (160-200 g) were implanted with implants, and six in each group were injected with VPS26 overexpression lentivirus (LV-VPS26 group), negative control lentivirus (LV-nc group) and saline (blank control group).Micro-CT analysis , HE and oil red O staining were used to evaluate the osseointegration of the implants and lipid droplets formation of the femur samples. Twenty female 6-week nude mice (30-40 g) were divided into five groups and subcutaneously implanted with osteogenic BMSC non-transfected and transfected LV-VPS26, LV-nc, shVPS26, and shscr lentivirus on the back. Samples were used to observe ectopic osteogenesis. Results: The mRNA expression levels of ALP in the high-fat group BMSC after overexpression of VPS26 (1.56±0.09) were significantly higher than those of the negative control (1.01±0.03) (t=10.09, P<0.001), while those of peroxisome proliferator-activated receptor-γ (PPAR-γ) (t=6.44, P<0.001) and fatty acid-binding protein4 (FABP4) (t=10.01, P<0.001) were lower than those of the negative control. Western blotting results showed that compared with the negative control, protein expression of ALP and Runt-related transcription gene 2 was enhanced in the high-fat group BMSC after overexpression of VPS26 while PPAR-γ and FABP4 were inhibited. ALP activity of BMSC in the high-fat group was stronger after overexpression of VPS26, and the formation of lipid droplets was weaker than that in negative control. The results of immunofluorescence, immunoprecipitation and dual luciferase reporter assays showed co-localization and interaction of VPS26 with β-catenin and a significant 43.10% increase in the TOP/FOP ratio (t=-3.17, P=0.034). VPS26 overexpression enhanced osseointegration and decreased the number of lipid droplets in high-fat rat and enhanced ectopic osteogenesis of nude mice. Conclusions: VPS26 activated osteogenesis differentiation and inhibited adipogenic differentiation of BMSCs through Wnt/β-catenin pathway, promoting osseointegration of high-fat rat implants and ectopic osteogenesis of nude mice.

Abstract
Objective: To understand the transition rules of cognitive frailty and its influencing factors in the elderly in China and provide evidence for the early intervention of cognitive frailty. Methods: Data were retrospectively collected from China Health and Retirement Longitudinal Study with 3 round consecutive survey (2011, 2013, 2015) and the state of the subjects were classified into four categories: robust-normal cognitive, cognitive impairment, physical frailty, and cognitive frailty. A multi-state Markov model was established to explore the transition rules of cognitive frailty and its influencing factors. Results: A total of 3 470 older adults were included, and 350 (10.09%) had cognitive frailty at baseline. After two years, the probability of cognitive frailty in the cognitive impairment population was higher than that in people with physical frailty (31.6% vs. 7.6%). Persons with cognitive frailty were more likely to become physical frailty (29.7% vs. 15.6%). Being women (HR=1.599, 95%CI: 1.058-2.417), comorbidity (HR=3.035, 95%CI: 1.090-8.450), and depression (HR=1.678, 95%CI: 1.153-2.441) were the risk factors associated with cognitive frailty in the elderly, while being educated (HR=2.367, 95%CI: 1.567-3.575) was a protective factor for the transition of cognitive frailty to physical frailty. Conclusions: The prevalence of cognitive frailty is relatively high in the elderly in China. Those with cognitive impairment have a higher probability of cognitive frailty. Gender, education level, comorbidity, and depression are the main influencing factors for the occurrence and transition of cognitive frailty.

Abstract
Objective: To construct and compare the dynamic prediction models of the risk of mild cognitive impairment (MCI) in the elderly based on six different cognitive function scales. Methods: Based on longitudinal data from the Alzheimer's Disease Neuroimaging Initiative from 2005 to 2020, Mini-mental state examination (MMSE), functional activities questionnaire (FAQ), Alzheimer's disease assessment scale-cognitive (ADAS-Cog) 11, ADAS-Cog13, ADAS delayed word recall (ADASQ4), and Rey auditory verbal learning test (RAVLT)_immediate were used as longitudinal cognitive function evaluation indicators to assess the longitudinal changes in cognitive function. The joint model was used to analyze association between indicators variation trajectory and survival outcome MCI, and construct the risk prediction model of MCI in the elderly, the linear mixed model was constructed the longitudinal sub-model which described the evolution of a repeated measure over time, a proportional hazards model was constructed the survival sub-model, and the two sub-models were connected through the correlation parameter (α). The areas under the receiver operator characteristic curve (AUC) were used to evaluate the predictive efficacy of the model in the follow-up period of (t, t+Δt). The starting point t was selected at the 30th, 42nd, and 54th month, and the Δt was selected as 15 and 21 months. Based on the prediction model, an example of the research object was selected for dynamic individual predictions of the risk of MCI. Results: Finally, 544 older adults (aged 60 years and above) with normal baseline cognitive status were included, of which 119 cases (21.9%) had MCI during the follow-up process were regarded as the case group, and 425 cases remained normal as the control group. The joint model suggests that the longitudinal trajectories of the six evaluation indicators are all related to the risk of MCI (P<0.001). The risk of MCI decreased by 32.3% (HR=0.677, 95%CI: 0.541-0.846) and 10.8% (HR=0.892, 95%CI: 0.865-0.919) for each one-point increase of MMSE and RAVLT_immediate longitudinal scores. The risk of MCI increased by 53.2% (HR=1.532, 95%CI: 1.393-1.686), 36.2% (HR=1.362, 95%CI: 1.268-1.462), 23.2% (HR=1.232, 95%CI: 1.181-1.285), and 85.1% (HR=1.851, 95%CI:1.629-2.104) for each one-point increase of FAQ, ADAS-Cog11, ADAS-Cog13, and ADASQ4 longitudinal scores. AUC results show that RAVLT_immediate (0.760 2) and ADASQ4 (0.755 8) have higher average prediction efficiency, followed by ADAS-Cog13 (0.743 7), ADAS-Cog11 (0.715 3), FAQ (0.700 8) and MMSE (0.629 5). ADASQ4 joint model was used to provide a dynamic individual prediction of the risk of MCI. The average probability of MCI after five years of follow-up and ten years of follow-up in the example individuals were 8% and 40%, respectively. Conclusions: The RAVLT_immediate and ADASQ4 scales, which are only for memory tests, have high accuracy in predicting the risk of MCI. Using the RAVLT_immediate and ADASQ4 scales as longitudinal cognitive function evaluation indicators to construct a joint model, the results can provide a basis for realizing MCI risk prediction for the elderly.

Abstract
Abstract Objective To develop an SNP Panel for East Asian population, which has a high individual identification rate and the capability of ancestry analysis. Methods The 55 SNP Panel by Professor KIDD of Yale University and the 128 SNP Panel by Professor SELDIN of Davis School of California University, 170 SNP Panel in total was used as the basis and its test data in the East Asian population was collected. The genetic parameters of SNP loci were calculated and combined with the results of heatmap analysis to screen SNP loci suitable for East Asian population. Some Tibetan and Han samples were tested. The possibility of using the SNP loci in ancestry inference was analyzed by means of STRUCTURE analysis, principal component analysis and heatmap analysis. Results A Panel with 45 SNPs (45 SNP Panel) was screened out, and the average genetic parameters of each SNP were better than 170 SNP Panel, with the same ancestry analysis and inference ability. Conclusion In terms of ancestry inference information, the 45 SNP Panel can completely replace the 170 SNP Panel and achieve the same ancestry analysis and inference ability. In genetic parameters, 45 SNP Panel is better than 170 SNP Panel in the East Asian population, which shows its important potential forensic application value.

Abstract
OBJECTIVE To observe the effect of acupuncture combined with rehabilitation training on cognitive function and amino acid metabolism in children with cerebral palsy. METHODS Twenty children with cerebral palsy (cerebral palsy group) were randomly divided into an acupuncture and rehabilitation group (11 cases) and a rehabilitation group (9 cases), and 10 healthy children were included as the normal group. The rehabilitation group was treated with rehabilitation training, 30 min each time; on the basis of rehabilitation training, the acupuncture and rehabilitation group was treated with acupuncture at Sishenzhen, Zhisanzhen, Naosanzhen, Niesanzhen, Dazhui (GV 14), Shenzhu (GV 12), Mingmen (GV 4), etc. The Sishenzhen (left and right points) and the ipsilateral Niesanzhen were respectively connected with a group of electrodes, intermittent wave, frequency of 2 Hz for 30 min. Both groups were treated once every other day, three times a week, totaling for 3 months. The Gesell developmental diagnostic scale (GESELL) was used to evaluate the developmental quotient (DQ) scores before and after treatment, and the blood samples of children with cerebral palsy before and after treatment and normal children were collected for amino acid metabolomics. RESULTS Compared before treatment, the DQ scores of adaptation, fine motor and social in the acupuncture and rehabilitation group was increased after treatment (P<0.05), and the DQ score of fine motor in the rehabilitation group was increased after treatment (P<0.05). Compared with the normal group, the serum L-glutamate, L-ornithine, L-tyrosine, L-methionine and L-arginine in the cerebral palsy group were down-regulated, and L-histidine, L-citrulline, 5-hydroxylysine and L-glutamine were up-regulated before treatment. The functional pathways mapped by different metabolites between the cerebral palsy group and the normal group included arginine biosynthesis, arginine and proline metabolism, etc. Compared with the cerebral palsy group, the serum L-histidine was decreased, and L-citrulline showed decreasing trend in the acupuncture and rehabilitation group after treatment. CONCLUSION Acupuncture combined with rehabilitation training could improve cognitive function in children with cerebral palsy, and the effect may be related to the down-regulation of L-histidine and L-citrulline metabolism.

Abstract
Luteoloside (Lute), a bioactive natural ingredient, widely exists in nature and possesses hepatoprotective and hepatocyte proliferation-promoting properties. This study aimed to investigate whether Lute could counteract non-alcoholic fatty liver disease (NAFLD)-caused hepatocyte damage via its stimulation of hepatocyte regeneration efficacy and to explore the involved mechanism. LO2 cells and primary hepatocytes were used to examine the hepatocyte proliferation effects of Lute under physiological conditions and in the palmitic acid (PA)- induced in vitro model of NAFLD. STAT3 and cell cycle-related proteins (cyclin D1, c-myc and p21) were evaluated by Western blot. Under physiological conditions, LO2 cells and primary hepatocytes treated with various concentration of Lute for 12 and 24 h showed increased hepatocyte proliferation, especially with 20 μM treatment for 24 h. More notably, under the model conditions, co-incubation with 20 μM of Lute also markedly reversed PA-induced inhibition of cell proliferation and viability in primary hepatocytes. Mechanistically, Lute could activate STAT3 and subsequently increase cyclin D1 and cmyc expression, which positively regulates cell cycle progression, and decrease expression of p21, an inhibitor of cell cycle progression. Furthermore, Luteinduced hepatocyte proliferation-promoting efficacy was abolished by STAT3 inhibitor stattic. Collectively, Lute can alleviate PA-induced hepatocyte damage via activating STAT3-mediated hepatocyte regeneration.

Abstract
The effects of adverse childhood experiences on adult health has aroused increasing concern in the world in recent years, but limited studies have been conducted in China. This study synthesized the measurement of adverse childhood experiences, the association between adverse childhood experiences and the prevalence common chronic diseases in adulthood and possible mechanisms. It was found that though measurement range of adverse childhood experiences might be different among studies, current used measurement scales basically met the requirement of disease prevention. Most categories of adverse childhood experiences were positively related to risk of common chronic diseases, and the relationship was influenced by social economic status, sex and age. However, people with exposure to famine in childhood had lower prevalence of hypertension compared with those without the exposure. The possible mechanisms might be that the occurrence of adverse childhood experiences might damage physiological functions or increase the adoption of poor healthy behaviors and lifestyles, and finally increased the risk of chronic diseases directly or indirectly. While premature death due to adverse childhood experiences might reverse the association because of nonrandom selection. It is necessary for us to select appropriate indexes of adverse childhood experiences and conduct more studies to prove the association between adverse childhood experiences and prevalence of common chronic diseases in adulthood and explore the related mechanism for the better prevention of chronic diseases in China.

Abstract
INTRODUCTION Cerebral palsy is the most common motor disability of childhood. Spastic cerebral palsy accounts for 60% to 70% of cases. Research has shown that acupuncture can improve the quality of life of children with cerebral palsy, but the mechanism of action remains unclear. This study aims to determine the effectiveness of acupuncture for treatment of children with spastic cerebral palsy and to assess the value of multimodal magnetic resonance imaging (MRI) and ambulatory electroencephalogram (EEG) for evaluation of treatment effect. METHODS AND ANALYSIS This randomized controlled trial will enroll a total of 72 children with CP from 2 hospitals-Jiangsu Province Hospital of Chinese Medicine and Nanjing State Hospital of Pediatric-with 36 participants from each hospital. Patients will be randomly assigned (1:1 ratio) to receive "Tonifying Kidney and Invigorating Brain" acupuncture treatment plus standardized physical rehabilitation treatment (treatment group) or only standardized physical rehabilitation (control group). All participants will receive 3 treatment sessions per week for 3 consecutive months; they will then be followed up for another 3 months. The primary outcome measures will include multimodal magnetic resonance imaging (MRI), ambulatory electroencephalogram (EEG), and Gesell Developmental Diagnostic Schedules. The secondary outcome measures will include Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Functional Independence Measure (WeeFIM), and Modified Ashworth Scale score. Outcome measures (including primary and secondary outcome measures) were collected at the baseline, 3 months and 6 months prior to the intervention.Ethics and dissemination PATIENTS CONSENT:: Obtained. ETHICS APPROVAL The central independent ethics committee of Jiangsu Province Hospital of Traditional Chinese Medicine approved the protocol (2017NL-115-02). SAFETY CONSIDERATIONS Routine blood tests and liver and kidney function tests will be conducted to exclude patients with severe heart, liver, or kidney diseases. The same examinations will be performed again at the end of the study to detect any possible side effects. Possible acupuncture-related adverse events (e.g., fainting, needle stick injury, local infection, subcutaneous hematoma, and low-grade fever) will be documented. Serious adverse events will be reported to the principal investigator immediately. All unexpected and unintended responses, even those not necessarily related to the acupuncture intervention, will be documented as adverse events. CASE DROPOUT MANAGEMENT Participants have a right to withdraw from the study at any time if they feel uncomfortable upon receiving the treatments or being diagnosed with serious complications or diseases. They will then be referred to the preferred department for further treatment and management. If cases of dropout, the researcher need to contact the participant to reason the problem out, collect and record all the necessary assessments on the last visit as well as the date of last visit. All data available until the date of withdrawal will be stored for further statistical analysis. DISCUSSION This research is being conducted to assess the value of acupuncture as an intervention for rehabilitation of children with spastic cerebral palsy and also to evaluate the usefulness of multimodal MRI and ambulatory EEG for identifying changes in brain function. TRIAL REGISTRATION This trial is registered with Chinese Clinical Trials Register, ChiCTR 1900024546 (registered 15 July 2019; retrospective registration, http://www.chictr.org.cn/showproj.aspx?proj=35763).

Abstract
Post inflammatory irritable bowel syndrome (PI-IBS), a subset of IBS, is characterized by symptoms of visceral pain, bloating, and changed bowel habits that occur post initial episode of intestinal infection. Gut microbial dysbiosis or inflammation plays a key role in the pathogenesis of abdominal hypersensitivity of PI-IBS. Electroacupuncture (EA) stimulation results in an alleviated PI-IBS-associated symptom. This study investigated the effect of EA on IL-18 and gut microbial dysbiosis in one visceral hypersensitive rat models with PI-IBS. A trinitrobenzene sulfonic acid (TNBS)-induced visceral hypersensitivity rat model was developed. EA stimulation was applied to the ST25 and ST36 acupoints. Animals were assessed using abdominal withdrawal reflex (AWR) scores to determine the development of colonic visceral hypersensitivity. The 16S rRNA was used to correlate microbial diversity. IL-18 expression in colon was quantified by quantitative real-time PCR and western blotting. We identified that model rats had an increased visceral hypersensitivity to colorectal distention at different distention pressures compared with the normal group. Sensitivity to colorectal distention decreased after EA stimulation. The composition of the fecal microbiota was different between groups. Specifically, in the model group Empedobacter, Psychrobacter, Enterococcus, Butyricimonas, Vampirovibrio, Kurthia, Intestinimonas, Neisseria, Falsiporphyromonas, Bilophila, Fusobacterium, Alistipes, Veillonella, Flavonifractor, Clostridium XlVa were more abundant affected genera, whereas Lactobacillus was enriched in normal rats. EA stimulation was correlated with significant decrease in the phyla of Fusobacteria. The mRNA and protein levels of IL-18 were higher in the model group. Meanwhile, EA stimulation attenuated this response. In a word, our findings suggest that PI-IBS is associated with significant increase in IL-18 levels as well as an alteration in microbiome diversity. These changes can be reversed with EA treatment. EA stimulation has a positive effect in alleviating symptoms of visceral hypersensitivity and protecting the gastrointestinal tract.

Abstract
Professor SHENG Can-ruo is a well-known national veteran doctor with over 70 years of clinical experience. He has unique academic thoughts and clinical experience for common diseases and some difficult and complicated diseases. This paper mainly introduces professor SHENG 's syndrome-differentiation thought and experience of acupoint selection for hot flashes. It is emphasized that common hot flashes, such as hot flashes and night sweats, are different between yin and yang. While regulating yin and yang, more attention should be paid to ying-wei harmony, which is not only suitable for women's perimenopausal syndrome, but also for a series of clinical diseases caused by refractory drugs such as endocrine therapy after breast cancer surgery. At the same time of acupoint selection based on syndrome differentiation, a more rational prescriptions should be made according to the duration of the disease and the experience acupoints to improve the clinical efficacy.

Abstract
Objective: To explore the cognitive functions of the elderly aged 60 years and above in Xiamen, and whether TV watching time would affect those functions. Methods: We conducted a cross-sectional study on 3 230 registered individuals aged 60 years and above in Xiamen from July to October in 2016 with a multi-stage random sampling method. Montreal Cognitive Assessment (MoCA) was used to measure cognitive functions and ordinal logistic regression was used to quantify their associations with TV watching time. Results: A total of 2 944 respondents were included in this study. The overall age of them was (70.14±7.81) years. 51.49% (n=1 516) of all participants were men. Overall, the mean scores of MoCA in general and each subdomain cognitive function were 18.65±6.43 (general), 5.43±1.17 (orientation), 2.33±1.95 (memory), 1.80±1.52 (visuospatial), 1.66±1.20 (executive), 4.54±1.71 (attention), and 4.09±1.64 (language). Compared to those who watched TV no more than 2 hours per day, the elderly who did not watch TV had a worse performance in general, orientation, memory, visuospatial, executive, attention, language function, with OR (95%CI) values about 0.50 (0.35-0.71), 0.52 (0.37-0.73), 0.68 (0.48-0.96), 0.67 (0.47-0.96), 0.48 (0.34-0.67), 0.56 (0.41-0.77) and 0.45 (0.33-0.62), respectively. As to respondents who watched TV more than 2 hours but no more than 4 hours per day, they had a better performance in general, executive, attention, language, and orientation function with respective OR (95%CI) values about 1.24 (1.05-1.47), 1.20 (1.02-1.41), 1.41 (1.19-1.67), 1.51 (1.28-1.77) and 1.33 (1.08-1.64). Conclusion: The elderly aged 60 years and above in Xiamen City with TV watching time between 2 and 4 hours per day had a good performance in cognitive functions compared to those with more or less TV watching time.

Abstract
Objective: To establish a dynamic spatiotemporal spread modes of influenza A (H7N9) virus by using discrete geographic information and explore the spatiotemporal transmission of the virus. Methods: The gene sequences of H7N9 virus isolated from human in China, which were available from Global Initiative on Sharing Avian Influenza Data (GISAID), were used in alignment by using software BioEdit 7.0. Spatiotemporal spread model of H7N9 virus was established in a Bayesian statistical framework by using software BEAST 1.8.2. The symmetric substitution model and Bayesian stochastic search variable selection (BSSVS) were used to infer and verify the historical transmission route of H7N9 virus. Finally the spatiotemporal transmission route was presented by Google Earth software. Results: The transmission of avian influenza A (H7N9) virus originated in Shanghai and Hangzhou, and can be dated back to October 2012. In March and April 2013, it began to spread to the neighboring provinces. The transmission speed up in August and September and affected more than ten geographic positions within 3 months. Conclusion: Based on gene sequences and spatial geographic information, the transmission route of H7N9 virus was traced, which would support the avian influenza prevention and control as well as avian influenza virus tracing.

Abstract
The accidental release of radioactive materials from nuclear power plant leads to radioactive pollution. We apply an augmented ensemble Kalman filter (EnKF) with a chemical transport model to jointly estimate the emissions of Perfluoromethylcyclohexane (PMCH), a tracer substitute for radionuclides, from a point source during the European Tracer Experiment, and to improve the forecast of its dispersion downwind. We perturb wind fields to account for meteorological uncertainties. We expand the state vector of PMCH concentrations through continuously adding an a priori emission rate for each succeeding assimilation cycle. We adopt a time-correlated red noise to simulate the temporal emission fluctuation. The improved EnKF system rapidly updates (and reduces) the excessively large initial first-guess emissions, thereby significantly improves subsequent forecasts (r = 0.83, p < 0.001). It retrieves 94% of the total PMCH released and substantially reduces transport error (>80% average reduction of the normalized mean square error).

Abstract
To reduce the toxic effect on normal cells and improve the treatment effects of docetaxel, a novel transferrin modified docetaxel-loaded long circulating liposome for ovarian tumor was established for the first time. The transferrin-modified long-circulating liposomes loaded with docetaxel (TF-LP-DOC) were prepared by the post-insertion method and exhibited excellent characteristics in terms of particle size, encapsulation efficiency and stability. We investigated the targeting efficiencies of liposomes by the cellular uptake in vitro and biodistribution in vivo, and identified the therapeutic effects using cytotoxicity experiment (in vitro)and tumor growth inhibition (in vivo) on ovarian cancer. The in vitro and in vivo results showed that TF-LP-DOC were successfully established and presented an enhanced targeting ability. With decreased side effect and improved anti-tumor efficacy of chemotherapeutic drugs, TF-LP-DOC proved itself to be a very promising tumor targeted drug delivery system.
