Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.

Objective: The investigate the effects and mechanism of exosomes derived from human umbilical vein endothelial cells (HUVECs) on wound healing in diabetes rabbits. Methods: The experimental research methods were used. The primary vascular endothelial cells (VECs) and human skin fibroblasts (HSFs) were extracted from skin tissue around ulcer by surgical excision of two patients with diabetic ulcer (the male aged 49 years and the female aged 58 years) admitted to Xiangya Third Hospital of Central South University in June 2019. The cells were successfully identified through morphological observation and flow cytometry. The HUVEC exosomes were extracted by ultracentrifugation and identified successfully by morphological observation, particle size detection, and Western blotting detection. Twenty female 3-month-old New Zealand rabbits were taken to create one type 2 diabetic full-thickness skin defect wound respectively on both sides of the back. The wounds were divided into exosomes group and phosphate buffer solution (PBS) group and treated accordingly, with 20 wounds in each group, the time of complete tissue coverage of wound was recorded. On PID 14, hematoxylin-eosin staining or Masson staining was performed to observe angiogenesis or collagen fiber hyperplasia (n=20). The VECs and HSFs were co-cultured with HUVEC exosomes for 24 h to observe the uptake of HUVEC exosomes by the two kinds of cells. The VECs and HSFs were divided to exosome group treated with HUVEC exosomes and PBS group treated with PBS to detect the cell proliferation on 4 d of culture with cell count kit 8, to detect and calculate the cell migration rate at 24 and 48 h after scratch by scratch test, to detect the cell migration number at 24 h of culture with Transwell test, and to detect the mRNA expressions of nuclear factor-erythroid 2-related factor 2 (NRF2) and transcription activating factor 3 (ATF3) by real time fluorescence quantitative reverse transcription polymerase chain reaction. Besides, the number of vascular branches and vascular length were observed in the tube forming experiment after 12 h of culture of VECs (n=3). The VECs and HSFs were taken and divided into PBS group and exosome group treated as before, and NRF2 interference group, ATF3 interference group, and no-load interference group with corresponding gene interference. The proliferation and migration of the two kinds of cells, and angiogenesis of VECs were detected as before (n=3). Data were statistically analyzed with analysis of variance for repeated measurement, one-way analysis of variance, independent sample t test, and least significant difference test. Results: The time of complete tissue coverage of wound in exosome group was (17.9±1.9) d, which was significantly shorter than (25.2±2.3) d in PBS group (t=4.54, P<0.05). On PID14, the vascular density of wound in PBS group was significantly lower than that in exosome group (t=10.12, P<0.01), and the collagen fiber hyperplasia was less than that in exosome group. After 24 h of culture, HUVEC exosomes were successfully absorbed by VECs and HSFs. The proliferative activity of HSFs and VECs in exosome group was significantly higher than that in PBS group after 4 d of culture (with t values of 54.73 and 7.05, respectively, P<0.01). At 24 and 48 h after scratch, the migration rates of HSFs (with t values of 3.42 and 11.87, respectively, P<0.05 or P<0.01) and VECs (with t values of 21.42 and 5.49, respectively, P<0.05 or P<0.01) in exosome group were significantly higher than those in PBS group. After 24 h of culture, the migration numbers of VECs and HSFs in exosome group were significantly higher than those in PBS group (with t values of 12.31 and 16.78, respectively, P<0.01). After 12 h of culture, the mRNA expressions of NRF2 in HSFs and VECs in exosome group were significantly higher than those in PBS group (with t values of 7.52 and 5.78, respectively, P<0.05 or P<0.01), and the mRNA expressions of ATF3 were significantly lower than those in PBS group (with t values of 13.44 and 8.99, respectively, P<0.01). After 12 h of culture, the number of vascular branches of VECs in exosome group was significantly more than that in PBS group (t=17.60, P<0.01), and the vascular length was significantly longer than that in PBS group (t=77.30, P<0.01). After 4 d of culture, the proliferation activity of HSFs and VECs in NRF2 interference group was significantly lower than that in PBS group and exosome group (P<0.05 or P<0.01); the proliferation activity of HSFs and VECs in ATF3 interference group was significantly higher than that in PBS group (P<0.05 or P<0.01) and significantly lower than that in exosome group (P<0.05 or P<0.01). At 24 and 48 h after scratch, the migration rates of HSFs and VECs in ATF3 interference group were significantly higher than those in PBS group (P<0.05 or P<0.01) and significantly lower than those in exosome group (P<0.05 or P<0.01). At 24 and 48 h after scratch, the migration rates of HSFs and VECs in NRF2 interference group were significantly lower than those in PBS group and exosome group (P<0.05 or P<0.01). After 24 h of culture, the migration numbers of VECs and HSFs in ATF3 interference group were significantly more than those in PBS group (P<0.05) and significantly less than those in exosome group (P<0.05 or P<0.01); the migration numbers of VECs and HSFs in NRF2 interference group were significantly less than those in PBS group and exosome group (P<0.01). After 12 h of culture, the vascular length and number of branches of VECs in NRF2 interference group were significantly decreased compared with those in PBS group and exosome group (P<0.01); the vascular length and number of branches of VECs in ATF3 interference group were significantly increased compared with those in PBS group (P<0.01) and were significantly decreased compared with those in exosome group (P<0.01). Conclusions: HUVEC exosomes can promote the wound healing of diabetic rabbits by promoting the proliferation and migration of VECs and HSFs, and NRF2 and ATF3 are obviously affected by exosomes in this process, which are the possible targets of exosome action.

To systematically evaluate the efficacy and safety of Huaier Granules in the adjuvant treatment of primary liver cancer. The databases of CNKI, Wanfang, VIP, CBMdisc, PubMed, Cochrane Library and EMbase were searched by computer to screen out the randomized controlled trial on Huaier Granules combined with Western medicine in the treatment of primary liver cancer from the establishment of the databases to January 2020. Data extraction and quality evaluation were conducted for the included literature. Meta-analysis was conducted with RevMan 5.3 software, and evidence quality evaluation was conducted for the outcomes by GRADE profiler software. A total of 24 articles were included, with a total sample size of 2 664 cases. Meta-analysis showed that as compared with Western medicine alone, Huaier Granules combined with Western medicine could improve the objective remission rate(RR=1.38, 95%CI[1.26, 1.51], P<0.000 01), disease control rate(RR=1.29, 95%CI[1.10, 1.52], P=0.002) and 6-month survival rate(RR=1.20, 95%CI[1.10, 1.32], P<0.000 1), 1-year survival rate(RR=1.39, 95%CI[1.23, 1.58], P<0.000 01), 2-year survival rate(RR=1.95, 95%CI[1.28, 2.96], P=0.002), KPS score(MD=17.15, 95%CI[6.47, 27.83], P=0.002) and the improvement rate of KPS score(RR=2.02, 95%CI[1.47, 2.77], P<0.000 1), AFP decline rate(RR=1.40, 95%CI[1.20, 1.62], P<0.000 1), CD3~+(MD=17.34, 95%CI[9.28, 25.40], P<0.000 1), CD4~+(MD=8.62, 95%CI[1.59, 15.64], P=0.02), CD8~+(MD=1.95, 95%CI[-3.93, 7.82], P=0.52), CD4~+/CD8~+(MD=0.42, 95%CI[-0.33, 1.17], P=0.27); reduce the level of AFP(MD=-71.57, 95%CI[-80.42,-62.72], P<0.000 01), recurrence rate(RR=0.76, 95%CI[0.67, 0.85], P<0.000 01), and incidence of adverse reactions(RR=0.60, 95%CI[0.41, 0.89], P=0.01) in patients with primary liver cancer. According to the GRADE system, the evidence for outcome measures was low to very low. The results show that Huaier Granules have certain efficacy and high safety in adjuvant treatment of primary liver cancer, but its effect in reducing adverse reactions and improve immunity remains to be verified. Due to the poor quality of the included studies and evidences, the conclusions still need to be further verified by multi-center, large sample, and randomized double-blind controlled studies.

Network Meta-analysis was used to evaluate the efficacy and safety of different oral Chinese patent medicines combined with transcatheter arterial chemoembolization(TACE) in the treatment of primary liver cancer. Randomized controlled trials of oral Chinese patent medicines for primary liver cancer were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and EMbase databases from inception to May 2020. According to the Cochrane recommendation standard, the quality of the included articles was evaluated, and the data were analyzed by RevMan, R software and GeMTC software. A total of 10 kinds of oral Chinese patent medicines and 68 RCTs were included. Network Meta-analysis results showed that: as compared with TACE alone, 10 kinds of oral Chinese patent medicines combined with TACE showed advantages in effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence. In the pairwise comparison of oral Chinese patent medicines, the results showed that Cidan Capsules were superior to Jinlong Capsules and Xihuang Pills in 1-year survival rate. According to the probabi-lity ranking results: Shenyi Capsules and Ganfule were more obvious in improving the effective rate; Cidan Capsules and Shenyi Capsules were more effective in improving the 1-year survival rate; Pingxiao Capsules and Shenyi Capsules had better efficacy in improving 2-year survival rate; Huaier Granules and Shenyi Capsules had better efficacy in improving the quality of life; Huisheng Oral Liquid and Ganfule were more effective in reducing the incidence of adverse reactions(such as nausea, vomiting and leukocytosis). The current evidence showed that oral Chinese patent medicine combined with TACE was superior to TACE alone in efficacy and safety. In terms of the effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence, the optimal treatment measures were Shenyi Capsules, Cidan Capsules, Pingxiao Capsules, Huaier Granules and Huisheng Oral Liquid in turn. However, due to the limitations of the research, the current level of evidence is not high, and clear conclusions and evi-dence strength still need to be further verified and improved by high-quality researches.

A high performance liquid chromatography( HPLC) method was established for the fast,and precise determination of ten nucleosides in Fritillariae Cirrhosae Bulbus and its counterfeits. Then multivariate statistical analyses,such as clustering analysis,principal component analysis( PCA),and Fisher' s linear discriminant analysis( LDA),were conducted to establish a discriminant function model for an integrated analysis. The results indicated that data acquisition time of a single sample was shortened within 16 min by the HPLC method. In the range of 5-1 000 mg·kg~(-1),the mass concentrations of all nucleosides exhibited good linear relationships with the corresponding peak areas( R2> 0. 999). The spiked recoveries were in the range of 93. 83%-108. 9% with RSDs of0. 12%-1. 3%( n = 5). The limit of quantitation( LOQ) was 0. 98-4. 13 mg·kg~(-1). As revealed by the clustering analysis,Fritillariae Cirrhosae Bulbus and the counterfeits could be discriminated into two clusters based on the content of nucleosides. Fisher's LDA could achieve this discrimination,while PCA dimension reduction failed. The accuracy of the discriminant function model established on the screened characteristic indicators reached 97. 5%. The present study proposed a new identification method of Fritillariae Cirrhosae Bulbus with one-dimensional indicators,which is simple,accurate,and reliable. It can provide a scientific basis for further optimizing the identification techniques for Fritillariae Cirrhosae Bulbus and inspiration for quality control strategy development of Chinese medicinal materials.

Whether in the West or the East, the connection between the ear and the rest of the body has been explored for a long time. Especially in the past century or more, the relevant theoretical and applied research on the ear has greatly promoted the development of ear therapy, and finally the concept of transcutaneous auricular vagus nerve stimulation (taVNS) has been proposed. The purpose of taVNS is to treat a disease non-invasively by applying electrical current to the cutaneous receptive field formed by the auricular branch of the vagus nerve in the outer ear. In the past two decades, taVNS has been a topic of basic, clinical, and transformation research. It has been applied as an alternative to drug treatment for a variety of diseases. Based on the rapid understanding of the application of taVNS to human health and disease, some limitations in the development of this field have also been gradually exposed. Here, we comprehensively review the origin and research status of the field.

OBJECTIVE: To investigate the effect of moderate-intensity aerobic exercise on the differential expression of rat atrial muscle Proteomics and genes, which provide research basis for the rehabilitation of chronic cardiovascular diseases and exercise -induced cardiac remodeling research. METHODS: Twenty male SD rats were randomly divided into control group and experimental group (=10) according to body weight. Rats in the experimental group were trained (6 days per week),which lasted for 4 weeks of moderate-intensity aerobic exercise at a rate of 24 m·min for 40 min (load intensity equivalent to 60%~70% VO). The proteins were separated by two dimensional gel electrophoresis, and the tandem time-of- flight mass spectrometer technique was used to identify 13 candidate target protein spots. The expression levels of these 13 protein spots were up-regulated more than 5 times or down -regulated to below 1/5. The mRNA of six target proteins were detected by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: By software analysis, the experimental group compared with the control group, there were 8 protein points which their expression reduced more than 4/5 and 5 protein points up-regulated more than 5 times, 13 proteins were identified by mass spectrometry protein spots, the final identification results acquired 8 proteins and a unknown protein of molecular mass 54 KDa, such as:pyruvate dehydrogenase E1α1, mitochondrial aconitate hydratase, protein disulfide isomerase A3, methylmalonic acid semialdehyde dehydrogenase, mitochondrial dihydrolipoic acid dehydrogenase, isovaleryl coenzyme A dehydrogenase, glutathione synthetase, mitogen-activated protein kinase 3 and so on. Compared with the control group, the mRNA expression of methylmalonic acid semialdehyde dehydrogenase in the atrial muscle of rats was decreased after 4 weeks of moderate aerobic exercise (<0.05), the mRNA expression levels of mitochondria Ⅱ lipoic acid dehydrogenase, protein disulfide isomerase A3, mitochondrial aconitate hydratase and glutathione synthetase were decreased (>0.05); The mRNA expression level of isopentenyl-CoA dehydrogenase was increased (>0.05). The results indicated that the mRNA expression level was not completely consistent with the changes in mass spectrometry identification results. CONCLUSIONS The 4 weeks moderate-intensity aerobic exercise induced ignificant changes of rats atrial muscle protemics. The majority of the 13 identified target proteins in this experiment are energy metabolism enzymes. The majority of the expression of the target protein and the mRNA expression in the atrial muscle is inconsistent and different. Exercise may affect the regulation of gene transcription or downstream translation and modification of these target proteins, resulting in the change of differential expression.
