Meta-Analysis
BACKGROUND
Numerous studies have explored the anti-tumor effect of berberine (BBR), but little clinical evidence guides the use of BBR in cancer patients.
OBJECTIVES
Our aim was to investigate the impact of BBR on various cancers in healthy animals to promote the transformation from bench to bed.
SEARCH METHODS
PubMed, Embase, Springer, and Cochrane databases were searched from January 2000 to October 2018 for relevant articles.
SELECTION CRITERIA
Only published studies focusing on the relationship between BBR and various cancers in vivo were qualified. Two review authors independently assessed the risk of bias for each study, and any disagreement was resolved by discussion or by involving a third assessor.
RESULTS
A total of 26 studies from 2000 to 2018, focusing on various cancer types, including breast cancer, liver cancer, colorectal cancer, nasopharyngeal carcinoma, lung cancer, gastric cancer, neuroepithelial cancer, endometrial carcinoma, esophageal cancer, tongue cancer, cholangiocarcinoma, and sarcoma were included. Overall, BBR reduced tumor volume (SMD =3.72, 95% CI: 2.89, 4.56, Z = 8.73, p < 0.00001) and tumor weight (SMD =2.35, 95% CI: 1.51, 3.19, Z = 5.50, p < 0.00001) in a linear The dose-response relationship (Pearson r = - 0.6717, p < 0.0001 in tumor volume analysis; Pearson r = - 0.7704, p < 0.0005 in tumor weight analysis). BBR inhibited angiogenesis in tumor tissues (SMD = 4.29, 95% CI: 2.14, 6.44, Z = 3.92, p < 0.00001), but it had no significant effect on the body weight of experimental animals (SMD = 0.11, 95% CI: - 0.70, 0.92, Z = 0.27, p = 0.78). Publication bias was not detected.
CONCLUSION
BBR exerted anti-tumor effects in a variety of tumors in vivo, especially breast cancer and lung cancer, and the evidence was still insufficient in colorectal cancer and gastric cancer.

Meta-Analysis
BACKGROUND
Prediction of survival after the treatment of hepatocellular carcinoma (HCC) has been widely investigated, yet remains inadequate. The application of artificial intelligence (AI) is emerging as a valid adjunct to traditional statistics due to the ability to process vast amounts of data and find hidden interconnections between variables. AI and deep learning are increasingly employed in several topics of liver cancer research, including diagnosis, pathology, and prognosis.
AIM
To assess the role of AI in the prediction of survival following HCC treatment.
METHODS
A web-based literature search was performed according to the Preferred Reporting Items for Systemic Reviews and Meta-Analysis guidelines using the keywords "artificial intelligence", "deep learning" and "hepatocellular carcinoma" (and synonyms). The specific research question was formulated following the patient (patients with HCC), intervention (evaluation of HCC treatment using AI), comparison (evaluation without using AI), and outcome (patient death and/or tumor recurrence) structure. English language articles were retrieved, screened, and reviewed by the authors. The quality of the papers was assessed using the Risk of Bias In Non-randomized Studies of Interventions tool. Data were extracted and collected in a database.
RESULTS
Among the 598 articles screened, nine papers met the inclusion criteria, six of which had low-risk rates of bias. Eight articles were published in the last decade; all came from eastern countries. Patient sample size was extremely heterogenous ( = 11-22926). AI methodologies employed included artificial neural networks (ANN) in six studies, as well as support vector machine, artificial plant optimization, and peritumoral radiomics in the remaining three studies. All the studies testing the role of ANN compared the performance of ANN with traditional statistics. Training cohorts were used to train the neural networks that were then applied to validation cohorts. In all cases, the AI models demonstrated superior predictive performance compared with traditional statistics with significantly improved areas under the curve.
CONCLUSION
AI applied to survival prediction after HCC treatment provided enhanced accuracy compared with conventional linear systems of analysis. Improved transferability and reproducibility will facilitate the widespread use of AI methodologies.

Review
Lung cancer is one of the leading causes of cancer-related deaths worldwide that presents a substantial peril to human health. Non-Small Cell Lung Cancer (NSCLC) is a main subtype of lung cancer with heightened metastasis and invasion ability. The predominant treatment approaches currently comprise surgical interventions, chemotherapy regimens, and radiotherapeutic procedures. However, it poses significant clinical challenges due to its tumor heterogeneity and drug resistance, resulting in diminished patient survival rates. Therefore, the development of novel treatment strategies for NSCLC is necessary. Ferroptosis was characterized by iron-dependent lipid peroxidation and the accumulation of lipid reactive oxygen species (ROS), leading to oxidative damage of cells and eventually cell death. An increasing number of studies have found that exploiting the induction of ferroptosis may be a potential therapeutic approach in NSCLC. Recent investigations have underscored the remarkable potential of natural products in the cancer treatment, owing to their potent activity and high safety profiles. Notably, accumulating evidences have shown that targeting ferroptosis through natural compounds as a novel strategy for combating NSCLC holds considerable promise. Nevertheless, the existing literature on comprehensive reviews elucidating the role of natural products inducing the ferroptosis for NSCLC therapy remains relatively sparse. In order to furnish a valuable reference and support for the identification of natural products inducing ferroptosis in anti-NSCLC therapeutics, this article provided a comprehensive review explaining the mechanisms by which natural products selectively target ferroptosis and modulate the pathogenesis of NSCLC.

Gut microbiome is proved to affect the activity of immunotherapy in certain tumors. However, little is known if there is universal impact on both the treatment response and adverse effects (AEs) of immune checkpoint inhibitors (ICIs) across multiple solid tumors, and whether such impact can be modulated by common gut microbiome modifiers, such as antibiotics and diet. A systematic search in PubMed followed by stringent manual review were performed to identify clinical cohort studies that evaluated the relevance of gut microbiome to ICIs (response and/or AEs, 12 studies), or association of antibiotics with ICIs (17 studies), or impact of diet on gut microbiome (16 studies). Only original studies published in English before April 1st, 2020 were used. Qualified studies identified in the reference were also included. At the phylum level, patients who had enriched abundance in and almost universally had better response from ICIs, whereas those who were enriched in universally presented with unfavorable outcome. Mixed correlations were observed for in relating to treatment response. Regarding the AEs, correlated to higher incidence whereas were clearly associated with less occurrence. Interestingly, across various solid tumors, majority of the studies suggested a negative association of antibiotic use with clinical response from ICIs, especially within 1-2 month prior to the initiation of ICIs. Finally, we observed a significant correlation of plant-based diet in relating to the enrichment of "ICI-favoring" gut microbiome ( = 0.0476). Gut microbiome may serve as a novel modifiable biomarker for both the treatment response and AEs of ICIs across various solid tumors. Further study is needed to understand the underlying mechanism, minimize the negative impact of antibiotics on ICIs, and gain insight regarding the role of diet so that this important lifestyle factor can be harnessed to improve the therapeutic outcomes of cancer immunotherapy partly through its impact on gut microbiome.

Meta-Analysis
CONTEXT
Accumulated experimental evidence suggests that resveratrol (RSV) may have an effect on acute kidney injury (AKI) by inhibiting inflammation. However, the credibility of the evidence for this practice is unclear.
OBJECTIVE
This study investigated the effect of RSV on AKI and the underlying mechanism.
METHODS
We searched PubMed, EMBASE, and Web of Science from 2005 to April 2022 for controlled animal trials assessing the effect of conventional resveratrol versus placebo on renal function outcome after AKI. This study was registered within the International Prospective Register of Systematic Reviews (PROSPERO) as number CRD42022329596.
RESULTS
We retrieved 455 studies, 25 studies comprising data of 436 animals that met the inclusion criteria. Our meta-analysis suggested that RSV treatment was significantly associated with lower levels of serum creatinine (Scr) and blood urea nitrogen (BUN). The greatest effects were recorded in low-dose (<20 mg/kg/day) groups rather than in high-dose (> 20 mg/kg/day) groups. For time-response effects, subgroup analysis indicated that intervention duration of RSV can influence the treatment effect, and more beneficial effects were observed when studies had a drug administration time of <2 weeks.
DISCUSSION AND CONCLUSIONS
This systematic review of animal AKI studies showed a consistently favourable effect of RSV as compared to placebo on renal function outcomes that increased with lower TNF-α, IL-6, and IL-1β. RSV has a more beneficial effect on SA-AKI animal models than the others. When the RSV intervention dose was low (< 20 mg/kg/day) and the intervention time was <2 weeks, more benefits could be observed.

Polycystic ovary syndrome is the most common endocrine disorder in women. Today, medicinal plants have been considered by women, especially in the reproductive and pregnancy ages. Multiple drug treatments and the length of the treatment period often lead to incomplete treatment by patients. Therefore, due to the side effects of chemical drugs, this study was conducted to assess investigate the effect of pomegranate seed oil on polycystic ovary syndrome. The prevalence of polycystic ovary syndrome is increasing by 15 to 20% and clinically includes oligomenorrhea or amenorrhea, hirsutism, and often infertility. Databases such as Cochran library, Medline, PubMed, SID, and Science Direct were used to access the related articles. To collect the required information, first, the articles that had one of the keywords of medicinal plants, polycystic ovary syndrome, plant, pomegranate extract, and menstrual irregularities in their text were searched in databases. All studies from 1985 to 2021 are included in the study. Conjugated linolenic acid (CLN) is a group of geometric and positional isomers of linolenic acid in which double bonds are conjugated. CLN has been reported to have a very strong cytotoxic effect on tissue tumor cells in the body, preventing cancer, reducing the accumulation of triacylglycerol in the liver, polycystic ovary syndrome, and LDL cholesterol in the blood. So far, seven CLN isomers have been identified, including ponic acid in pomegranate seed oil. Conjugated linoleic acid (CLA) is a group of situational and geometric isomers of linoleic acid in which double bonds are conjugated. The positive effects of the two main CLA isomers (cis-9, trans-11, and trans-10, cis-12) include inhibiting the growth of cancer, reducing the risk of atherosclerosis, and reducing body fat.

The effect of ginsenoside Rg3 combined with chemotherapy on immune function in non-small cell lung cancer: A systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
The occurrence and development of non-small cell lung cancer (NSCLC) are closely related to the immune status of the tumor-host. The immunosuppression caused by tumor cells and toxic side effects produced by chemotherapeutic drugs results in a decrease in immune function, ultimately leading to the failure of clinical chemotherapy treatment. Ginsenoside Rg3 has been clinically reported to have positive effects in enhancing immune function in patients. Thus, we screened and evaluated the quality of the evidence regarding the benefits of ginsenoside Rg3 and conducted a meta-analysis to assess the impact on improving immune function in NSCLC.
METHODS
The PubMed, EMBASE, Cochrane Library, CNKI, Weipu (VIP), and Wanfang databases were searched in this study, all from the time of library construction to January 2023.
RESULTS
In total,12 trials with a sample size of 1008 cases were included based on the eligible criteria. The results showed that compared with first-line chemotherapy alone, the combination of ginsenoside Rg3 and first-line chemotherapy could better improve level of the CD3+ T lymphocytes [mean difference (MD) = 4.72; 95% confidence intervals (CI): 3.92, 5.53; P < .00001], CD4+ T lymphocytes (MD = 4.93; 95% CI: 4.61, 5.26; P < .00001), CD8+ T lymphocytes (MD = 2.67; 95% CI: 0.93, 4.37; P = .003), CD4+/CD8+ T lymphocytes (MD = 0.20; 95% CI: 0.09, 0.32; P = .0006), increase the activity of nature killer cells (MD = 2.11; 95% CI: 0.58, 3.63; P = .007), recover the decline of the white blood cell count induced by chemotherapy, and improve the clinical efficacy for patients.
CONCLUSION
This study confirmed that ginsenoside Rg3 has some efficacy advantages for improving immune function in patients with NSCLC.

Medicinal plants are the chief components in the different oriental formulations in different traditional medical systems worldwide. As a thriving source of medicine, the medicinal plants with antituberculosis (TB) properties inspire the pharmacists to develop new drugs based on their active components or semimetabolites. In the present review, the anti-TB medicinal plants were screened from the scientific literatures, based on the botanical classification and the anti-TB activity. The obtained anti-TB medicinal plants were categorized into three different categories, , 159 plants critically examined with a total 335 isolated compounds, 131 plants with their crude extracts showing anti-TB activity, and 27 plants in literature with the prescribed formula by the traditional healers. Our systemic analysis on the medicinal plants can assist the discovery of novel and more efficacious anti-TB drugs.

Fermented wheat germ extract (FWGE; trade name AVEMAR) is a natural compound derived from industrial fermentation of wheat germ. Its potential anticancer properties has emerged from recent studies. The aim of this systematic review is to summarize the data available in the scientific literature concerning the in vitro activity of FWGE on malignant cells. A systematic review of English articles in electronic databases has been performed. The primary outcomes of the review regarded types of cancer cell lines subjected to the investigation and the main results concerning cell viability, proliferation, and apoptosis observed within the studies. Sixteen articles were included in the final qualitative analysis. Various types of cancer cells treated with FWGE have been analyzed, showing mainly cytotoxic effects, alteration of the cell cycle, antiproliferative effects, and induction of apoptosis. FWGE can be a promising drug component in cancer treatment; however, further in vitro and in vivo studies are necessary to prove its effectiveness and safety in humans.
