RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Jinfu'an Decoction (JFAD) is a traditional Chinese decoction used in lung cancer treatment to improve patient quality of life and survival. Previous research has established that JFAD has a significant therapeutic effect on non-small cell lung cancer (NSCLC), although the underlying molecular mechanisms have not been largely underexplored. AIM OF THE STUDY: We used network pharmacology to identify the putative active ingredients of JFAD and conducted experimental studies to determine the potential molecular mechanism of JFAD in NSCLC treatment. MATERIALS AND METHODS: The herbal components in JFAD-containing serum were identified by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS), and targets associated with the anti-lung cancer metastasis effects of JFAD were retrieved from various databases. The Database for Annotation, Visualization and Integrated Discovery (DAVID) was used to perform Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. Next, the protein-protein interactions network and the "JFAD-Chemical Component-Target-KEGG Pathway" network were constructed. The network pharmacology findings were confirmed by in vitro and in vivo experiments. In vitro experiments were conducted to assess cell viability by CCK8 assay, cell cycle analysis by propidium iodide (PI) assay, and migration and invasion ability of cells by the transwell assay. In vivo experiments were performed to assess the efficacy of JFAD on the tumor by observing the growth of transplanted tumor models in nude mice and evaluated by in vivo bioluminescence imaging. Moreover, we assessed the effect of JFAD on the PI3K/Akt signaling pathway and proteins of Lumican, p120ctn, and specific RhoGTP enzyme family members (RhoA, Rac1, and RhoC) by Western Blot and immunohistochemistry. RESULTS: 32 herbal components were identified in the JFAD-containing serum, which potentially acted on 229 targets related to lung cancer metastasis. Network pharmacology results suggested that JFAD may treat lung cancer metastasis by targeting the PI3K/Akt pathway via regulating multiple core targets. Our experiments showed that JFAD suppressed the proliferation of A549 cells in vitro, induced cell cycle arrest, and reduced the migration and invasion ability of A549 cells. Our in vivo study revealed that JFAD inhibited tumor growth in a nude mouse model. Additionally, we found that JFAD could downregulate the expression of the PI3K/Akt pathway and affect the expression of Lumican, p120ctn, and specific RhoGTPase family members. CONCLUSIONS: In conclusion, through network pharmacology, we have unveiled the underlying mechanisms that link the various components, targets, and pathways influenced by JFAD in the context of lung cancer metastasis. Our experimental results suggest that the oncostatic effects of JFAD may be achieved by upregulating the expression of Lumican/p120ctn and downregulating the levels of specific RhoGTPase family members, which in turn block the PI3K/Akt signaling pathway.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Blood-activating and stasis-transforming traditional Chinese medicines (BAST) are a class of herbs that have the effect of dilating blood vessels and dispersing stagnation. Modern pharmaceutical research has demonstrated that they are capable of improving hemodynamics and micro-flow, resist thrombosis and promote blood flow. BAST contain numerous active ingredients, which can theoretically regulate multiple targets at the same time and have a wide range of pharmacological effects in the treatment of diseases including human cancers. Clinically, BAST have minimal side effects and can be used in combination with Western medicine to improve patients' quality of life, lessen adverse effects and minimize the risk of recurrence and metastasis of cancers. AIM OF THE REVIEW: We aimed to summarize the research progression of BAST on lung cancer in the past five years and present a prospect for the future. Particularly, this review further analyzes the effects and molecular mechanisms that BAST inhibit the invasion and metastasis of lung cancer. MATERIALS AND METHODS: Relevant studies about BSAT were collected from PubMed and Web of science. RESULTS: Lung cancer is one of the malignant tumors with the highest mortality rate. Most patients with lung cancer are diagnosed at an advanced stage and are highly susceptible to metastasis. Recent studies have shown that BAST, a class of traditional Chinese medicine (TCM) with the function of opening veins and dispersing blood stasis, significantly improve hemodynamics and microcirculation, prevent thrombosis and promote blood flow, and thereby inhibiting the invasion and metastasis of lung cancer. In the current review, we analyzed 51 active ingredients extracted from BAST. It was found that BAST and their active ingredients contribute to the prevention of invasion and metastasis of lung cancer through multiple mechanisms, such as regulation of EMT process, specific signaling pathway and metastasis-related genes, tumor blood vessel formation, immune microenvironment and inflammatory response of tumors. CONCLUSIONS: BSAT and its active ingredients have showed promising anticancer activity and significantly inhibit the invasion and metastasis of lung cancer. A growing number of studies have realized their potential clinical significance in the therapy of lung cancer, which will provide substantial evidences for the development of new TCM for lung cancer therapy.

RESUMO

BACKGROUND: Accumulating evidence shows that women experience serious psychological distress after terminating their pregnancy for fetal anomaly (TOPFA). Although the number of studies on psychosocial interventions (PSIs) for TOPFA women has increased, access to evidence-based support for medical staff who provide care to TOPFA women remains limited. A systematic review was conducted to provide an overview of available PSIs. METHODS: Nine major electronic databases in available in English and Chinese languages were searched to identify articles published from the databases' inception to November 2021. Our participants were TOPFA women; interventions were PSIs; the comparison was no limits; outcomes were psychological distress including depression, anxiety, and post-traumatic stress (PTSD); and study designs were experimental studies including randomized controlled trials (RCTs) and quasi-experimental studies. The Joanna Briggs Institute Critical Appraisal Checklist for RCTs and quasi-experimental studies was used to assess the quality of evidence. Subsequently, synthesis without meta-analysis of the findings was completed. RESULTS: A total of 1,730 studies were identified from the initial database, 37 of which were included in this research. The interventions tested included cognitive therapy, mindfulness, sandplay therapy, psychological counseling, family support, peer support, empathy nursing, bereavement care, solution-focused psychological nursing, and staged psychological nursing. Four of these studies were RCTs. Most interventions were implemented in hospitals in China by nurses. However, few studies reported details on implementation procedures, and the studies presented substantial heterogeneity. Most of the included studies were judged to be of high risk of bias. DISCUSSION: Although this review was limited by search strategies and most of the included studies were of low quality, it still provided some tentative support for PSIs for the treatment of TOPFA women. Further research is warranted to investigate the effects of specific components on TOPFA women by using randomized controlled designs and reporting intervention manuals based on psychotherapeutic theory.

RESUMO

Although nanomaterials have the potential to improve human life, their sideline effects on human health seem to be inevitable and still are unknown. Some studies have investigated the genotoxicity of alumina nanoparticles (AlNPs); however, this effect is still unclear due to insufficient evaluation and conflicting results. Using a battery of standard genotoxic assays, the present study offers evidence of the genotoxicity associated with aluminum oxide (alumina) at NP sizes of 50 and 13 nm, when compared with bulk alumina (10 µm). The genotoxicity induced by alumina at bulk and NP sizes was evaluated with Ames test, comet test, micronucleus assay and sperm deformity test. The mechanism related to the induction of reactive oxygen species was explored as well. Our results showed that AlNPs (13 and 50 nm) were able to enter cells and induced DNA damage, micronucleus in bone marrow, sperm deformation and reactive oxygen species induction in a time-, dose- and size-dependent manner. Therefore, we conclude that AlNPs (13 and 50 nm), rather than bulk alumina, induce markers of genotoxicity in mice, with oxidative stress as a potential mechanism driving these genotoxic effects.

RESUMO

BACKGROUND: Greater than 70% of patients with cancer experience chemotherapy-induced nausea and vomiting. In the current study, the authors examined the effects of electrostimulation of the K1 acupoint located on the sole of the foot because it is believed to have the potential to control chemotherapy-induced nausea and vomiting. METHODS: In this trial, 103 patients diagnosed with primary or metastatic liver cancer were recruited before transcatheter arterial infusion (TAI) of cisplatin or oxaliplatin and randomized to either group A (51 patients who were treated with the antiemetic tropisetron and acustimulation at the K1 acupoint for 20 minutes approximately 1 to 2 hours before TAI on the first day and then daily for the subsequent 5 days) or group B (52 patients who were treated with tropisetron and electrostimulation at a placebo point on the heel). The rate, intensity, and duration of nausea and vomiting were collected at baseline and then daily for 5 days after TAI. Quality of life was assessed daily using the MD Anderson Symptom Inventory and the EuroQoL scale. RESULTS: No differences were found between groups A and B with regard to the incidence and degree of nausea or vomiting on day 1 or the following 5 days. Patients in group A had better EuroQoL scores compared with patients in group B (72.83 in group A vs 65.94 in group B; P =.04) on day 4 but not on the other days. No group differences were noted at any time point for MD Anderson Symptom Inventory scores. CONCLUSIONS: Electrostimulation of K1 combined with antiemetics did not result in initial prevention of cisplatin-induced or oxaliplatin-induced nausea or vomiting.

RESUMO

BACKGROUND: Xerostomia (dry mouth) after head/neck radiation is a common problem among cancer patients. Quality of life (QOL) is impaired, and available treatments are of little benefit. This trial determined the feasibility of conducting a sham-controlled trial of acupuncture and whether acupuncture could prevent xerostomia among head/neck patients undergoing radiotherapy. METHODS: A sham controlled, feasibility trial was conducted at Fudan University Shanghai Cancer Center, Shanghai, China among patients with nasopharyngeal carcinoma undergoing radiotherapy. To determine feasibility of a sham procedure, 23 patients were randomised to real acupuncture (N=11) or to sham acupuncture (N=12). Patients were treated three times/week during the course of radiotherapy. Subjective measures were the Xerostomia Questionnaire (XQ) and MD Anderson Symptom Inventory for Head and Neck Cancer (MDASI-HN). Objective measures were unstimulated whole salivary flow rates (UWSFR) and stimulated salivary flow rates (SSFR). Patients were followed for 1 month after radiotherapy. RESULTS: XQ scores for acupuncture were significantly lower than sham controls starting in week 3 and lasted through the 1-month follow-up (all P's <0.001 except for week 3, which was 0.006), with clinically significant differences as follows: week 6 - RR 0.28 [95% confidence interval, 0.10, 0.79]; week 11 - RR 0.17 [95%CI, 0.03, 1.07]. Similar findings were seen for MDASI-HN scores and MDASI-Intrusion scores. Group differences for UWSFR and SSFR were not found. CONCLUSIONS: In this small pilot study, true acupuncture given concurrently with radiotherapy significantly reduced xerostomia symptoms and improved QOL when compared with sham acupuncture. Large-scale, multi-centre, randomised and placebo-controlled trials are now needed.

RESUMO

BACKGROUND: Xerostomia (dry mouth) after head/neck radiation is a common problem among cancer patients, and available treatments are of little benefit. The objective of this trial was to determine whether acupuncture can prevent xerostomia among head/neck patients undergoing radiotherapy. METHODS: A randomized, controlled trial among patients with nasopharyngeal carcinoma was conducted comparing acupuncture to standard care. Participants were treated at Fudan University Shanghai Cancer Center, Shanghai, China. Forty patients were randomized to acupuncture treatment and 46 to standard care. Patients were treated 3×/wk on the same days they received radiotherapy. Subjective measures included the Xerostomia Questionnaire and MD Anderson Symptom Inventory-Head and Neck (MDASI-HN). Objective measures were unstimulated and stimulated whole salivary flow rates. Patients were followed for 6 months after the end of radiotherapy. RESULTS: Xerostomia Questionnaire scores for acupuncture were statistically significantly lower than for controls starting in week 3 through the 6 months (P = .003 at week 3, all other P < .0001), with clinically significant differences as follows: week 11, relative risk (RR) 0.63 (95% confidence interval [CI], 0.45-0.87); 6 months, RR 0.38 (95% CI, 0.19-0.76). Similar findings were seen for MDASI-HN scores. Group differences emerged as early as 3 weeks into treatment for saliva (unstimulated whole salivary flow rate, P = .0004), with greater saliva flow in the acupuncture group at week 7 (unstimulated whole salivary flow rate, P < .0001; stimulated whole salivary flow rate, P = .002) and 11 (unstimulated whole salivary flow rate, P < .02; stimulated whole salivary flow rate, P < .03) and at 6 months (stimulated whole salivary flow rate, P < .003). CONCLUSIONS: Acupuncture given concurrently with radiotherapy significantly reduced xerostomia and improved quality of life.

RESUMO

AIM: To examine whether acupuncture can prevent prolonged postoperative ileus (PPOI) after intraperitoneal surgery for colon cancer. METHODS: Ninety patients were recruited from the Fudan University Cancer Hospital, Shanghai, China. After surgery, patients were randomized to receive acupuncture (once daily, starting on postoperative day 1, for up to six consecutive days) or usual care. PPOI was defined as an inability to pass flatus or have a bowel movement by 96 h after surgery. The main outcomes were time to first flatus, time to first bowel movement, and electrogastroenterography. Secondary outcomes were quality of life (QOL) measures, including pain, nausea, insomnia, abdominal distension/fullness, and sense of well-being. RESULTS: No significant differences in PPOI on day 4 (P = 0.71) or QOL measures were found between the groups. There were also no group differences when the data were analyzed by examining those whose PPOI had resolved by day 5 (P = 0.69) or day 6 (P = 0.88). No adverse events related to acupuncture were reported. CONCLUSION: Acupuncture did not prevent PPOI and was not useful for treating PPOI once it had developed in this population.

RESUMO

OBJECTIVE: To search for an effective method for controlling nausea and vomiting induced by chemotherapy. METHODS: Eighty-eight cases of hepatic cancer with interventional therapy of Cisplatin were randomly divided into a treatment group and a control group, 44 cases in each group. The treatment group were treated with an antiemetic and electroacupuncture at Yongquan (KI 1), and the control group only with the antiementic. The controlling rates for nausea and vomiting were compared between the two groups. RESULTS: The controlling rates for acute nausea, vomiting and delayed vomiting in the treatment group were better than those in the control group (P < 0.05). CONCLUSION: Electroacupuncture at Yongquan (KI 1) can better prevent and improve the symptoms of nausea and vomiting in the patient with chemotherapy of Cisplatin.
