- Abstract：Tumor-associated macrophages (TAMs) play a key role in all stages of tumorigenesis and tumor progression. TAMs secrete different kinds of cytokines, chemokines, and enzymes to affect the progression, metastasis, and resistance to therapy depending on their state of reprogramming. Therapeutic benefit in targeting TAMs suggests that macrophages are attractive targets for cancer treatment. Chinese materia medica (CMM) is an important approach for treating cancer in China and in the Asian region. According to the theory of Chinese medicine (CM) and its practice, some prescriptions of CM regulate the body's internal environment possibly including the remodeling the tumor microenvironment (TME). Here we briefly summarize the pivotal effects of TAMs in shaping the TME and promoting tumorigenesis, invasion, metastasis and immunosuppression. Furthermore, we illustrate the effects and mechanisms of CMM targeting TAMs in antitumor therapy. Finally, we reveal the CMM's dual-regulatory and multi-targeting functions on regulating TAMs, and hopefully, provide the theoretical basis for CMM clinical practice related to cancer therapy.Keywords：tumor-associated macrophages;tumor microenvironment;Chinese Materia Medica;Chinese Medicine;anti-tumor therapy

Published：2021-08-27 - Abstract：To determine whether additional Chinese medicine (CM) could prolong survival and improve the quality of life (QOL) in patients with advanced non-small cell lung cancer (NSCLC) compared with Western medicine (WM) alone. This was a multicenter, prospective cohort study. A total of 474 hospitalized patients with stage III–IV NSCLC were recruited and divided into 2 groups. Patients in the WM group received radiotherapy, chemotherapy, and optimal supportive therapy according to the National Comprehensive Cancer Network (NCCN) guidelines. In the integrative medicine (IM) group, individualized CM (Chinese patent medicines and injections) and WM were administered. The primary end point was overall survival, and the secondary end points were time to disease progression, adverse events, and QOL. Follow-up clinical examinations and chest radiography were performed every 2 months. The median survival was 16.60 months in the IM group and 13.13 months in the WM group (P<0.01). The incidences of loss of appetite, nausea, and vomiting in the IM group were significantly lower than those in the WM group (P<0.05). The QOL based on Functional Assessment of Cancer Therapy-Lung in the IM group was markedly higher than that in the WM group at the fourth course (P<0.05). Additional CM may prolong survival and improve the QOL patients with NSCLC. The adverse effects of radio- and chemotherapy may be attenuated as CM is used in combination with conventional treatments.Keywords：advanced non-small cell lung cancer;Chinese Medicine;Integrative Medicine

Published：2021-08-27 - Abstract：To evaluate the prognosis effect of Chinese herbal medicines (CHMs) for benefiting qi and activating blood circulation adjunctive to conventional treatment in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). A total of 702 patients with ACS who underwent PCI were enrolled and randomly assigned to receive conventional treatment plus CHMs for benefiting qi and activating blood circulation (treatment group, 351 cases) or conventional treatment alone (control group, 351 cases) for 6 months. Six months later, all patients received conventional treatment alone. Follow-ups were scheduled at 6th, 12th, 18th, 24th month after enrollment in April 2008, and the final follow-up visit was during September 2011 and November 2011. The primary endpoint was the composite of cardiac death, nonfatal myocardial infarction or revascularization (PCI or coronary artery bypass grafting); and the secondary endpoint was the composite of re-admission for ACS, congestive heart failure, nonfatal stroke or other thrombus events. A total of 621 (88.59%) patients completed 35.4±3.8 months follow-up, while 80 (11.41%) patients withdrew from the trial (41 in the treatment group and 39 in the control group). The incidence of primary endpoint was 5.7% (20 patients) in the treatment group versus 10.86% (38 patients) in the control group [relative risk (RR): 0.53; 95% confidence interval (CI): 0.30, 0.88; P=0.013; absolute risk reduction (ARR):–0.052, 95% CI: –0.06, 0.01]. The incidence of secondary endpoint was 5.98% (21 patients) in the treatment group versus 10.28% (36 patients) in control group (RR: 0.58, 95% CI: 0.33, 0.97, P=0.037; ARR: –0.043, 95% CI: 0.06, 0.01). Most of the primary and secondary endpoints were occurred in 18 months (84.50% in the treatment group versus 78.10% in the control group). CHMs for benefiting qi and activating blood circulation adjunctive to conventional treatment improved clinical outcomes for patients with ACS after PCI in long-term follow-up.Keywords：long-term follow-up;Chinese Medicine;benefit qi and activate blood circulation;acute coronary syndrome;Percutaneous Coronary Intervention

Published：2021-08-27 - Abstract：To investigate the serum protein targets of Qianggu Decoction (强骨饮, QGD) on treating osteoporosis by the proteomics analysis using tandem mass tag (TMT) and liquid chromatographytandem mass spectrometry (LC-MS/MS). Twenty serum protein samples were recruited (10 patients with primary type I osteoporosis before and after QGD treatment) and the high abundance ratios protein was removed, two serum samples were extracted and labeled with TMT reagent. Then, mass spectrometric detection, identification of differentially expressed proteins and bioinformatics analysis of differentially expressed proteins were carried out. A total of 60 proteins were identified, within a 99% confidence interval, to be differentially regulated of which, 34 proteins were up-regulated and 26 proteins were down-regulated. Differentially expressed proteins analyzed by Gene Ontology (GO) annotation mainly get involved in 12 different biological processes, 7 types of cellular components, and 6 kinds of molecular functions. Angiotensinogen (AGT), stromelysin-1 (MMP3), heparanase (HPSE) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were screened as candidate protein targets of QGD treatment, which were related to metabolic mechanism of bone remodeling and/or bone collagen of osteoporosis. By the utilization of the protein-protein interaction network analysis tool named STRING10.0, it showed that AGT, MMP3, HPSE and GAPDH were located in the key node of the protein-protein interactions network. Furthermore, AGT, MMP3, HPSE and GAPDH were found to be directly related to BMP, MAPK, Wnt, SMAD and tumor necrosis factor ligand superfamily member 11 (TNFSF11) families. The proteomics analysis by using TMT combined with LC-MS/MS was a feasible method for screening the potential therapeutic targets associated with QGD treatment. It suggests that AGT, MMP3, HPSE and GAPDH may be candidate protein targets of QGD treatment which can be used as therapeutic effect monitor and early diagnosis of primary type I osteoporosis.Keywords：primary type I osteoporosis;tonifying qi and warming meridians;Chinese Medicine;proteomics

Published：2021-08-27 - Abstract：To investigate whether the dried root of Phellodendron amurense Ruprecht (Phellodendri cortex; PC) extract improves arthritic symptoms through anti-inflammatory and immune-modulatory effects in collagen-induced arthritis in mice. Rheumatoid arthritis (RA) was induced in male DBA/1 mice by immunization with type II collagen (ColII). CIA mice were divided into 5 groups (n=10 per a group) with normal, CIA control, PC extract (50 mg/kg and 100 mg/kg)-treated, and meloxicam (50 mg/kg)-treated as the reference drug. The PC extract or meloxicam were administered orally in CIA mice once a day for 14 days after arthritis induction. Arthritic score, levels of anti-ColII IgG2a antibody, prostaglandin E2 (PGE2), tumor necrosis factor (TNF)-α, and interleukin (IL)-17 in the sera of CIA mice were measured. Histopathological changes in the ankle joints of CIA mice were also analyzed by staining with hematoxylin and eosin (H and E), safranin-O and immunohistochemistry using anti-TNF-α and anti-IL-17 antibodies. The arthritic score was increased in CIA mice in a time-dependent manner, as were the serum levels of anti-ColII IgG2a antibody, PGE2, TNF-α, and IL-17. However, the oral administration of PC extract at 50 and 100 mg/kg in CIA mice significantly decreased the arthritic scores, and the serum levels of anti-ColII IgG2a, PGE2, TNF-α, and IL-17 compared with those in the CIA group (P<0.05 or P<0.01). Furthermore, histopathological improvement of the joint architecture in CIA mice was observed after administration of PC extract. PC extract also significantly inhibited the expression of TNF-α and IL-17 in the joints of CIA mice by suppressing the expression of their mRNA and proteins. PC extract may improve the pathological progression of RA through the inhibition of joint destruction by synovial inflammation and immune-stimulation, therefore, it would be a potential anti-arthritic agent in RA.Keywords：Phellodendron amurense;Phellodendri cortex;collagen-induced arthritis;anti-arthritic effect

Published：2021-08-27 - Abstract：To investigate the resistance and virulence profiles of uropathogenic Escherichia coli (UPEC) and its treatment by Chinese medicine (CM) Fuzheng Qingre Lishi Formula (扶正清热利湿方, FQLF). UPEC strains were isolated from recurrent urinary tract infections (UTIs) patients. Patient sensitivities to 17 antibiotics were tested by the disk diffusion method. Virulence genes were screened by plolymerase chain reaction. A mouse model was constructed using a multi-drug resistant and virulent UPEC strain and treated with FQLF or the antibiotic imipenem. The treatment efficacy was evaluated by bacterial clearance from urine and the urinary organs. A total of 90 UPEC strains were collected, and 94.4% of the isolates were resistant to at least 1 antibiotic. Approximately 66.7% of the UPEC strains were multi-drug resistant. More than one virulence gene was found in 85.6% of the isolates. The extended-spectrum β-lactamases (ESBL)-positive strains were more resistant than the negative ones. The virulence gene number was positively correlated with the resistance number (P<0.05). A mouse model was successfully constructed using UPEC10. Treatment with either FQLF or antibiotics significantly cleared bacteria from the mouse urine after 14 days. In the untreated control, the bacteria lasted for 28 days. FQLF treatment of the UTI mouse model greatly reduced the bacterial number in the kidney and bladder, but could not completely clear the bacteria. Multi-drug resistance is common among UPEC isolates, and the resistance is positively related with virulence. FQLF could treat UPEC UTIs, but could not completely clear the bacteria from the host.Keywords：urinary tract infection;uropathogenic Escherichia coli;Chinese Medicine;multi-drug resistance

Published：2021-08-27 - Abstract：To investigate the underlying mechanisms of cyclovirobuxinum D (Cvb-D) on alleviating cardiac hypertrophy in rats. Sprague-Dawley rats were randomly divided into 5 groups: control group; levothyroxine-induced cardiac hypertrophy group (model); levothyroxine-induced cardiac hypertrophy + Cvb-D group (Cvb-D); levothyroxine-induced cardiac hypertrophy + captopril group (captopril); levothyroxine-induced cardiac hypertrophy + SB203580 group (SB203580), n=10 for each group. Rats were daily administered the respective drugs continuously for14 days by gastric gavage. A rat model of cardiac hypertrophy was established by intraperitoneal injection of levothyroxine to investigate whether Cvb-D protects against cardiac hypertrophy by inhibiting the p38 mitogen-activated protein kinase (MAPK) signaling pathway and preventing apoptosis of cardiac cells. Treatment with Cvb-D significantly deceased left ventricle hypertrophy, improved the histopathology, hemodynamic conditions, and cardiac function in rats with cardiac hypertrophy. Compared with the normal control group, in rats with cardiac hypertrophy, expression of bax in the heart and phospho-p38 MAPK protein levels were significantly up-regulated (P<0.01 or 0.05), whereas the bcl-2 protein level was down-regulated (P<0.01). In contrast, Cvb-D treatment reversed the changes in bax and phospho-p38 MAPK protein levels but increased the bcl-2 protein level (P<0.01 or 0.05), and these effects were similar to those of captopril and SB203580 (a specific p38MAPK inhibitor) treatment. Furthermore, both Cvb-D, captopril and SB203580 reduced mRNA expression of p38α, p38β, c-fos, and c-jun mRNA, and Cvb-D had a stronger effect (P<0.01). These results demonstrate that Cvb-D protects against cardiac hypertrophy, which is possibly mediated by prevention of cardiac cell apoptosis and inhibition of the p38MAPK signaling pathway.Keywords：hypertrophic cardiomyopathy;cyclovirobuxinum D;apotosis;p38 mitogen-activated protein kinase;Chinese Medicine

Published：2021-08-27 - Abstract：To explore the scientific connotation of the discrepant pharmaceutical activities between the head and tail of Angelica sinensis diels (AS), an important herb extensively utilized in Chinese medicine, by the approach of transcriptome sequencing. Ten samples of AS were randomly collected in Min County, Gansu Province of China. Transcriptome sequencing of AS was accomplished in a commercial ILLumina HiSeq-2000 platform. The transcriptome of each head and tail of AS were fixed in a gene chip, and detected under the procedure of Illumina HiSeq-2000. Differentially expressed unigenes between the heads and tails of AS were selected by Shanghai Biotechnology Corporation (SBC) online analysis system, based on Gene Ontology, Kyoto Encyclopedia of Genes and Genomes and relevant bioinformatic database. Totally 63,585 unigenes were obtained from AS by high-throughput sequencing platform. Among which 3359 unigenes were identified as differentially expressed unigenes between the heads and tails of AS by SBC analysis system scanning. Of which 15 differentially expressed unigenes participate in the metabolic regulation of phenylpropanoid biosynthesis (PB) pathway and ferulic acid metabolites, in response to the distinguished pharmaceutical actions of the heads and tails of AS. Different content of ferulic acid in the heads and tails of AS is related to the differentially expressed genes, particularly involved in the PB pathway.Keywords：Angelica sinensis diels;transcriptome sequencing;Ferulic Acid;phenylpropanoid biosynthesis pathway;Chinese Medicine

Published：2021-08-27 - Abstract：To investigate the effect of electroacupuncture (EA) treatment on the expression of cyclooxygenase (COX) 2 and microglia in spinal cord by using rat model of neuropathic pain, and to probe into the relationship between COX 2 and microglia. The rats were randomly divided into 6 groups, including normal control group, model group, sham group, EA 1 group (distant acupoints + local acupoints), EA 2 group (local acupoints), and EA 3 group (distant acupoints). Thermal withdrawal latencies were evaluated at 1 day preoperatively and 3, 5 and 7 days postoperatively. At 7 days postoperatively, the spinal COX 2 mRNA was detected by reverse-transcription polymerase chain reaction. Double immunofluorescent staining technology was applied to screen and verify the relationship between altered COX 2 and microglia. Compared with the model group, thermal withdrawal latencies increased after EA treatment (P<0.01). The expressions of COX 2 mRNA were up-regulated in spinal cord of rat on day 7 after surgery (P<0.05). Compared with the model group, EA stimulation (EA 1 and EA 2 groups) reversed the up-regulation of COX 2 mRNA expression (P<0.05). EA 1 and EA 2 groups might have better treatment effect compared with the EA 3 group. Fluorescent images displayed COX 2 and microglia expressed at common areas. EA was effective in analgesic and anti-inflammatory. EA has decreased the expression of spinal COX 2 mRNA in the trend of the therapeutic effect of "distant acupoints + local acupoints", and "local acupoints" intervention may be superior to that of "distant acupoints" intervention. Microglia may be related to the formation of COX 2.Keywords：neuropathic pain;electroacupuncture;microglia;cyclooxygenase 2;Spinal Cord
