Guidelines for the clinical application of the Xihuang pill for the prevention and treatment of breast hyperplasia diseases.

CONTEXT: The Xihuang pill (XHP) is a traditional Chinese medicine formulation that has been historically used in the prevention and treatment of proliferative breast diseases. However, there is a lack of guidelines that offer recommendations for its clinical use. OBJECTIVE: The task force from the Chinese Guangdong Pharmaceutical Association aims to develop evidence-based guidelines for XHP to prevent and treat proliferative breast diseases. METHODS: We searched six Chinese and English electronic databases, including the China National Knowledge Infrastructure, the Chinese Scientific Journal Database, the Wanfang Medical Database, PubMed, and Embase, up to November 1, 2022. Publications (case reports, clinical observation, clinical trials, reviews) on using XHP to treat proliferative breast diseases were manually searched. The search terms were Xihuang pill, hyperplasia of the mammary gland, breast lump, and mastalgia. The writing team developed recommendations based on the best available evidence. RESULTS: Treatment should be customized based on syndrome identification. We recommend using XHP for the prevention and treatment of breast hyperplasia disease when a patient presents the following syndromes: concurrent blood stasis syndrome, concurrent phlegm-stasis syndrome, and concurrent liver fire syndrome. Safety indicators, including blood analysis and liver and kidney function monitoring, should be performed regularly during treatment. CONCLUSIONS: Current clinical evidence suggests that XHP can be used as a standalone treatment or in conjunction with other medications to prevent and manage breast hyperplasia diseases. More randomized controlled studies are warranted to establish high-quality evidence of its use.

Solamargine enhanced gefitinib antitumor effect via regulating MALAT1/miR-141-3p/Sp1/IGFBP1 signaling pathway in non-small cell lung cancer.

Lung cancer is the leading cause of cancer-related deaths worldwide. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) showed great therapeutic efficacy for non-small cell lung cancer (NSCLC) patients. However, acquired resistance severely limits the clinical application and efficacy of EGFR-TKIs. In the current study, we found that solamargine (SM), a natural alkaloid derived from the fruit of Lycium tomato lobelia, has been found to inhibit the progression of NSCLC and enhance the anticancer effect of EGFR-TKIs. In brief, SM significantly inhibited the cell viability of NSCLC cells and enhanced the anticancer effect of gefitinib (GFTN) and erlotinib (ERL). Mechanistically, SM decreased the expression of MALAT1 and induced miR-141-3p, whereas reduced SP1 protein levels. Interestingly, both MALAT1 and Sp1 have classical and conservative binding sites of miR-141-3p in their 3'-UTR regions. Silence of MALAT1 and overexpression of miR-141-3p both decreased the protein expression of Sp1. Subsequently, promoter activity and protein expression of IGFBP1 were upregulated by SM, which was not observed in cells with SP1 overexpression. Moreover, the inhibitory effect of SM on cell growth was significantly blocked by knockdown of IGFBP1 expression. More importantly, the combination of SM and GFTN synergistically inhibited the progression of lung cancer. Similar results were observed in experiments in vivo. Finally, the clinical relevance of MALAT1, Sp1 and IGFBP1 was further validated using bioinformatics analysis. Taken together, we confirmed that SM significantly enhanced the anticancer effect of EGFR-TKIs by regulating the MALAT1/miR-141-3p/Sp1/IGFBP1 signaling pathway. This study unravels a novel mechanism and suggests a new potential NSCLC-associated therapy.

The complementary and alternative roles of elemene injection in cancer: An umbrella review.

BACKGROUND: In the past, many meta-analyses (MAs) suggested that elemene injection (EI) played a complementary and alternative role in cancer treatment. However, some results were contradictory and a lot of evidences weren't classified. Thus, their clinical guidance effect was very limited. METHODS: Two reviewers independently retrieved 8 databases from their origin to May 19, 2023 and appropriate MAs were taken into consideration. A pooled analysis was conducted to merge results extracted from trials of included MAs. The methodological quality of MAs and the evidence certainty of pooled results were assessed. RESULTS: 31 MAs were taken into analysis with poor methodological quality. The main weaknesses were in the areas of heterogeneity analysis, bias risk, and literature selection. According to the present evidence, on the one hand, compared with conventional treatment (CT) alone, EI combined with CT may significantly enhance short-term or long-term efficacy and reduce adverse reactions caused by CT in multiple cancers. On the other hand, using EI alone also can improve ORR in the malignant (pleural) effusion and lessen the recurrence rate in bladder cancer obviously with fewer adverse reactions compared with CT alone. However, this evidence was rated as moderate to very low certainty mainly due to the risk of bias in clinical trials. CONCLUSION: EI may be a viable medication for the treatment of cancer although more convincing trials are still required to demonstrate its alternative and complementary benefits. Besides, it seems to have a broad potential for further development in immunotherapy, drug delivery technique, and predictive factor.

Solamargine inhibits the growth of hepatocellular carcinoma and enhances the anticancer effect of sorafenib by regulating HOTTIP-TUG1/miR-4726-5p/MUC1 pathway.

Hepatocellular carcinoma (HCC) is one of the most common primary malignancies. Drug resistance has significantly prevented the clinical application of sorafenib (SF), a first-line targeted medicine for the treatment of HCC. Solamargine (SM), a natural alkaloid, has shown potential antitumor activity, but studies about antitumor effect of SM are obviously insufficient in HCC. In the present study, we found that SM significantly inhibited the growth of HCC and enhanced the anticancer effect of SF. In brief, SM significantly inhibited the growth of HepG2 and Huh-7 cells. The combination of SM and SF showed a synergistic antitumor effect. Mechanistically, SM downregulated the expression of long noncoding RNA HOTTIP and TUG1, followed by increasing the expression of miR-4726-5p. Moreover, miR-4726-5p directly bound to the 3'-UTR region of MUC1 and decreased the expression of MUC1 protein. Overexpression of MUC1 partially reversed the inhibitory effect of SM on HepG2 and Huh-7 cells viability, which suggested that MUC1 may be the key target in SM-induced growth inhibition of HCC. More importantly, the combination of SM and SF synergistically restrained the expression of MUC1 protein. Taken together, our study revealed that SM inhibited the growth of HCC and enhanced the anticancer effect of SF through HOTTIP-TUG1/miR-4726-5p/MUC1 signaling pathway. These findings will provide potential therapeutic targets and strategies for the treatment of HCC.

Transcriptomic and Physiological Responses of Chlorella pyrenoidosa during Exposure to 17α-Ethinylestradiol.

17α-ethinylestradiol (17α-EE2) is frequently detected in water bodies due to its use being widespread in the treatment of prostate and breast cancer and in the control of alopecia, posing a threat to humans and aquatic organisms. However, studies on its toxicity to Chlorella pyrenoidosa have been limited to date. This study investigated the effects of 17α-EE2 on the growth, photosynthetic activity, and antioxidant system of C. pyrenoidosa and revealed related molecular changes using transcriptomic analysis. The cell density of algae was inhibited in the presence of 17α-EE2, and cell morphology was also altered. Photosynthetics were damaged, while reactive oxygen species (ROS), superoxide dismutase (SOD), and malondialdehyde (MDA) content increased. Further transcriptomic analysis revealed that the pathways of photosynthesis and DNA replication were affected at three concentrations of 17α-EE2, but several specific pathways exhibited various behaviors at different concentrations. Significant changes in differentially expressed genes and their enrichment pathways showed that the low-concentration group was predominantly impaired in photosynthesis, while the higher-concentration groups were biased towards oxidative and DNA damage. This study provides a better understanding of the cellular and molecular variations of microalgae under 17α-EE2 exposure, contributing to the environmental risk assessment of such hazardous pollutants on aquatic organisms.

Fuzheng Kang-Ai decoction enhances the effect of Gefitinib-induced cell apoptosis in lung cancer through mitochondrial pathway.

BACKGROUND: Our previous clinical study has shown that Chinese herbal medicine (CHM) Fuzheng Kang-Ai (FZKA) decoction is effective in treating advanced lung cancer patients through prolonging the drug resistance to Gefitinib (GFTN). Our basic study found that FZKA decoction could enhance the inhibition effect of GFTN in lung cancer by inactivating PI3K/Akt pathway. Moreover, our recent work showed that FZKA induced lung cancer cell apoptosis via STAT3/Bcl-2/Caspase-3 pathway. Thus in this study, we aim to elucidate how FZKA enhances the effect of GFTN in lung cancer from the perspective of cell apoptosis. METHODS: Cell proliferation and colony formation assay were performed to detect the cell growth inhibition. Flow cytometry and TUNEL assay were carried out to test the cell apoptosis. Mitochondrial membrane potential (MMP) assay was done to measure the alteration of MMP. Caspase-3/-9 activity assay was used to test the activity of caspase-3/-9. Western blot and qRT-PCR were done to detect the expression of STAT3 and Bcl-2 family as well as Caspase-3/-9 and Cyt-C at protein and mRNA levels, respectively. Transient transfection was performed to silence STAT3 using siSTAT3. Animal model was done to validate the molecular mechanisms in vivo and immunohistochemistry was done to detect the expression of Bax and Caspase-3. RESULTS: Firstly, our results showed that FZKA enhanced the inhibition effect of GFTN in lung cancer both in vitro and in vivo. Secondly, cell apoptosis was enhanced when treating lung cancer cells with both FZKA and GFTN, a process involving the mitochondria and the Bcl-2 family. And Bcl-2 family was involved in this process. Interestingly, STAT3 plays a critical role on mediating the above process. Last but not the least, the enhanced effect of cell apoptosis induction of GFTN by FZKA was validated in animal model. CONCLUSION: Our findings conclude that Fuzheng Kang-Ai decoction enhances the effect of GFTN-induced cell apoptosis in lung cancer through the mitochondrial pathway, providing a novel molecular mechanism by which FZKA sensitizes to GFTN by delaying drug resistance in treating lung cancer patients.

The regulation and interaction of colon cancer-associated transcript-1 and miR7-5p contribute to the inhibition of SP1 expression by solamargine in human nasopharyngeal carcinoma cells.

Nasopharyngeal carcinoma (NPC) is a common head and neck malignancy with higher incidence in Southern China and Southeast Asia. Solamargine (SM), a steroidal alkaloid glycoside, has been shown to have anticancer properties. However, the underlying mechanism involved remains undetermined. In this study, we showed that SM inhibited the growth of NPC cells. Mechanistically, we found that solamargine decreased lncRNA colon cancer-associated transcript-1 (CCAT1) and increased miR7-5p expression. There was a reciprocal interaction of CCAT1 and miR7-5p. In addition, SM inhibited the expression of SP1 protein and promoter activity, which was strengthened by miR7-5p mimics and inhibited by overexpressed CCAT1. MiR7-5p could bind to 3'-UTR of SP1 and attenuated SP1 gene expression. Exogenously expressed SP1 feedback resisted SM-increased miR7-5p expression and more importantly reversed SM-inhibited growth of NPC cells. Finally, SM inhibited NPC tumor growth in vivo. Collectively, our results show that SM inhibits the growth of NPC cells through reciprocal regulation of CCAT1 and miR7-5p, followed by inhibition of SP1 gene expression in vitro and in vivo. The interregulation and correlation among CCAT1, miR7-5p and SP1, and the feedback regulatory loop unveil the novel molecular mechanism underlying the overall responses of SM in anti-NPC.

lncRNA mortal obligate RNA transcript was downregulated in ovarian carcinoma and inhibits cancer cell proliferation by downregulating miRNA-21.

microRNA-21 (miRNA-21) is a well-characterized oncogenic miRNA in human cancers. In the present study, we found that miRNA-21 was upregulated, while long noncoding RNA Mortal Obligate RNA Transcript (lncRNA MORT), which has been reported to be silenced in 16 types of cancers, was downregulated in tumor tissues than in adjacent healthy tissues of patients with ovarian carcinoma. Expression of lncRNA MORT in tumor tissues was found to be significantly affected by tumor size but not by tumor metastasis. Expression levels of lncRNA MORT and miRNA-21 were significantly and inversely correlated in both tumor tissues and adjacent healthy tissues. Overexpression of lncRNA MORT inhibited miRNA-21, while miRNA-21 overexpression failed to significantly affect lncRNA MORT expression. Overexpression of lncRNA MORT inhibited, while miRNA-21 overexpression promoted the proliferation of cells of ovarian cancer cell lines. In addition, miRNA-21 overexpression partially reversed the inhibitory effects of lncRNA MORT overexpression on cancer cell proliferation. However, overexpression of lncRNA MORT showed no significant effects on cancer cell migration and invasion. Therefore, lncRNA MORT was downregulated in ovarian carcinoma and lncRNA MORT overexpression inhibited cancer cell proliferation, possibly by downregulating miRNA-21.

The enhancement of combination of berberine and metformin in inhibition of DNMT1 gene expression through interplay of SP1 and PDPK1.

Berberine (BBR), one of active alkaloid found in the rhizome, exhibited anti-cancer properties. We have showed that BBR inhibited growth of non-small cell lung cancer (NSCLC) cells through mitogen-activated protein kinase (MAPK)-mediated increase in forkhead box O3a (FOXO3a). However, the in-depth mechanism underlying the anti-tumor effects still remained to be elucidated. Herein, we further confirmed that BBR not only induced cell cycle arrest, but also reduced migration and invasion of NSCLC cells. Mechanistically, we observed that BBR reduced 3-phosphoinositide-dependent protein kinase-1 (PDPK1) and transcription factor SP1 protein expressions. Exogenously expressed SP1 overcame BBR-inhibited PDPK1 expression. Moreover, BBR inhibited DNA methyltransferase 1 (DNMT1) gene expression and overexpressed DNMT1 resisted BBR-inhibited cell growth. Intriguingly, overexpressed PDPK1 antagonized BBR-inhibited SP1 and DNMT1 expressions. Finally, metformin enhanced the effects of BBR both in vitro and in vivo. Collectively, we observe that BBR inhibits proliferation of NSCLC cells through inhibition of SP1 and PDPK1; this results in a reduction of DNMT1 expression. The interplay of PDPK1 and SP1 contributes to the inhibition of DNMT1 in response to BBR. In addition, there is a synergy of BBR and metformin. This study uncovers a new mechanism of BBR in combination with metformin for NSCLC-associated therapy.

[Effect of Fuzheng Kang'ai Recipe Combined Gefitinib on Lung Cancer A549 Cells and Its Mecha- nism Research].

Objective To observe the effect of Fuzheng Kang'ai Recipe (FKR) combined ge- fitinib on the proliferation and apoptosis of lung cancer A549 cells , and to study its potential synergistic mechanish with gefitinib. Methods The effects of FKR (0. 211, 0. 316, 0. 474, 0. 711, 1. 067, 1. 600, 2. 400, 3. 600 mg/mL) combined gefitinib (3. 95, 5. 92, 8. 18, 13. 33, 20. 00, 30. 00, 45. 00, 67. 50 µmol/ L) on the proliferation of A549 cells were detected by MTT assay. The apoptosis of A549 cells in the control group (complete culture medium) , FKR (1. 6 mg/mL) , gefitinib (45 µmol/L) , and FKR plus gefitinib (1. 6 mg/mL +45 µmol/L) were detected by flow cytometry (FCM). Their expressions of epidermal growth factor receptor (EGFR) , phosphorylating epidermal growth factor receptor ( p-EGFR) , enhancer of zeste homolog 2 (EZH2), peroxisome proliferator-activated receptor-γ ( PPAR-γ) , and P53 protein in A549 cells were detected by Western blot. Results Both FKR and gefitinib could inhibit the proliferation of A549 cells. The apoptotic rate was 12. 6% ±4. 5% in the FKR combined gefitinib group, obviously higher than that of the FKR group (4. 6% ± 0. 7%) and the gefitinib group (7. 8% ± 2. 7%) , showing statistical difference (P <0. 05). Compared with the control group, the expressions of p-EGFR and EZH2 were sig- nificantly down-regulated (P <0. 05) , the expressions of PPAR-γ and P53 protein were up-regulated in the FKR combined gefitinib group (P <0. 05); the expression of EZH2 was down-regulated in the gefitinib group and the FKR group (P <0. 05) ; the expression of PPAR-y was up-regulated in the FKR group (P < 0. 05). Compared with the gefitinib group, the expression of p-EGFR was down-regulated, and the expression of PPAR-γ was up-regulated in the FKR combined gefitinib group (both P <0. 05). Compared with the FKR group, the expression of p-EGFR was down-regulated in the FKR combined gefitinib group (P < 0. 05). Conclusions Combination of FKR and gefitinib could significantly inhibit the proliferation and growth of A549 cells,and induce cell apoptosis. Its potential synergistic mechanism of anti-tumor activities might be associated with down-regulating mRNA expressions of p-EGFR and EZH2, and up-regulating protein expressions of PPAR-y and P53.

[Combination of Jianpi Liqi Yiliu Formula with Cytokine-induced Killer Cell Treatment for Advanced Hepatocellular Carcinoma].

OBJECTIVE: To evaluate the clinical efficacy of Jianpi Liqi Yiliu Formula (JLYF) combined with cytokine-induced killer (CIK) cells for treating patients with advanced hepatocellular carcinoma (HCC). METHODS: Between January 2011 and January 2014, 60 advanced HCC patients were enrolled in this study, who were assigned to the treatment group and the control group according to their willingness for taking JLYF, 30 cases in each group. All patients received CIK cell treatment: 1 x 109-3 x 109 each time, by intravenous dripping from the 1st day to the 3rd day, once per day. Besides, patients in the treatment group took JLYF decoction, while those in the control group took Chinese medical decoction by syndrome typing. All patients received treatment of at least two cycles. The time to progression (TTP) , overall survival (OS), disease control rate (DCR), performance status scale (PS), Child-Pugh scale, and adverse reactions were observed, and subgroup analyzed. RESULTS: To May 31, 2014, all patients reached the clinical endpoint. TTP was 3.5 months (95% Cl: 3.30-4.10) in the treatment group, better than that (2.5 months, 95% CI: 2.32-2.68) of the control group (P < 0.05). DCR was 36.7% in the treatment group and 30.0% in the control group (P > 0.05). OS was 5.2 months (95% CI: 4.53-5.87) in the treatment group and 4.6 months (95% CI: 4.06-5.14) in the control group (P > 0.05). The PS scale was 1.60 ± 0.10 after treatment, lower than that (1.80 ± 0.09) before treatment in the treatment group (P < 0.05). When the PS scale was 0-2 or Child-Pugh scale was class A, TTP was longer in the treatment group than in the control group (P < 0.05). No adverse reaction occurred in the two groups during the treatment course. CONCLUSIONS: The combination of JLYF with ClK cell treatment could prolong advanced HCC patients' TTP, improve PS scale, as compared with syndrome typed Chinese medical decoction treatment group. Besides, when the PS scale was 0-2 or Child-Pugh scale was class A, it was a better treatment program for advanced HCC patients.

ß-elemene inhibited expression of DNA methyltransferase 1 through activation of ERK1/2 and AMPKα signalling pathways in human lung cancer cells: the role of Sp1.

ß-elemene, a compound derived from Rhizoma zedoariae, is a promising new plant-derived drug with broad-spectrum anticancer activity. However, the underlying mechanism by which this agent inhibits human lung cancer cell growth has not been well elucidated. In this study, we showed that ß-elemene inhibits human non-small cell lung carcinoma (NSCLC) cell growth, and increased phosphorylation of ERK1/2, Akt and AMPKα. Moreover, ß-elemene inhibited expression of DNA methyltransferase 1 (DNMT1), which was not observed in the presence of the specific inhibitors of ERK (PD98059) or AMPK (compound C). Overexpression of DNMT1 reversed the effect of ß-elemene on cell growth. Interestingly, metformin not only reversed the effect of ß-elemene on phosphorylation of Akt but also strengthened the ß-elemene-reduced DNMT1. In addition, ß-elemene suppressed Sp1 protein expression, which was eliminated by either ERK1/2 or AMPK inhibitor. Conversely, overexpression of Sp1 antagonized the effect of ß-elemene on DNMT1 protein expression and cell growth. Taken together, our results show that ß-elemene inhibits NSCLC cell growth via ERK1/2- and AMPKα-mediated inhibition of transcription factor Sp1, followed by reduction in DNMT1 protein expression. Metformin augments the effect of ß-elemene by blockade of Akt signalling and additively inhibition of DNMT1 protein expression. The reciprocal ERK1/2 and AMPKα signalling pathways contribute to the overall responses of ß-elemene. This study reveals a potential novel mechanism by which ß-elemene inhibits growth of NSCLC cells.

Targeting signal transducer and activator of transcription 3 contributes to the solamargine-inhibited growth and -induced apoptosis of human lung cancer cells.

Solamargine (SM), a major steroidal alkaloid glycoside extracted from a traditional Chinese medicinal herb, Solanum nigrum L. (SNL), has been shown to inhibit growth and induce apoptosis of various cancer cells. However, the molecular mechanisms underlying this are poorly understood. In this study, we showed that SM inhibited growth and induced apoptosis of non-small-cell lung cancer (NSCLC) cells in a time- and dose-dependent manner. To further explore this, we found that SM increased phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK) in a time-dependent fashion. SM also inhibited phosphorylation and protein expression of signal transducer and activator of transcription 3 (Stat3), a transcription factor, which was abrogated by the SB203580, a specific inhibitor of p38 MAPK. In addition, SM induced protein expression of p21, one of cyclin-dependent kinase inhibitors, and this was not observed in cell overexpression of Stat3 or cells treated with SB203580. Finally, while silencing of Stat3 had no further effect, exogenous expression of Stat3 overcame the effect of SM on cell proliferation. Collectively, our results show that SM inhibits proliferation and induces apoptosis in lung cancer cells through p38 MAPK-mediated suppression of phosphorylation and protein expression of Stat3, followed by inducing Stat3 downstream effector p21. This unveils a potential new mechanism by which SM inhibits growth of human lung cancer cells.

[Treating primary liver cancer patients by Pi-strengthening and Qi-regulating method: univariate and multivariate analyses of their prognoses].

OBJECTIVE: To evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program. METHODS: Clinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out. RESULTS: The 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05). CONCLUSION: The prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.

Efficacy and Safety of Huachansu as an Adjuvant Therapy for Non-Small Cell Lung Cancer: An Overview of Systematic Reviews and Meta-Analyses.

OBJECTIVE: The purpose of this overview is to assess systematic reviews (SRs)/ meta-analyses (MAs) of Huachansu (HCS) combination chemotherapy for treating non-small cell lung cancer (NSCLC) and provide summarized evidence for clinical decision making. METHODS: From the creation of the database to JUNE 2023, 8 databases in English and Chinese were searched. SRs/MAs that met the inclusion and exclusion criteria were included. Two reviewers independently screened research, extracted data and assessed methodological quality, risk of bias, report quality and evidence quality by using relevant criteria from AMSTAR-2, ROBIS scale, PRISMA, and GRADE system. RESULTS: The short-term effect, long-term effect, quality of life improvement, safety and pain relief effect in 8 included SRs/MAs were assessed in this overview according to quantitative synthesis. Results assessed by AMSTAR-2, PRISMA, and ROBIS were generally unsatisfactory, with the results of the AMSTAR-2 assessment showing that all of them were of low or critically low quality; the number of items in the included research that were fully reported (compliance was 100%) by the PRISMA checklist was only 50%, while there were 38.10% of the research reporting less than 60% completeness; the ROBIS assessment showed a small number of systems to be low risk of bias. In addition, 26 items were rated as moderate quality, while 50.94% of items were rated as low or critically low quality by GRADE. CONCLUSION: HCS may be a promising adjuvant therapy for NSCLC. However, high-quality SRs/MAs and randomized control trials (RCTs) should be conducted to provide sufficient evidence so as to draw a definitive conclusion.

Reprogramming of glucose metabolism: The hallmark of malignant transformation and target for advanced diagnostics and treatments.

Reprogramming of cancer metabolism has become increasingly concerned over the last decade, particularly the reprogramming of glucose metabolism, also known as the "Warburg effect". The reprogramming of glucose metabolism is considered a novel hallmark of human cancers. A growing number of studies have shown that reprogramming of glucose metabolism can regulate many biological processes of cancers, including carcinogenesis, progression, metastasis, and drug resistance. In this review, we summarize the major biological functions, clinical significance, potential targets and signaling pathways of glucose metabolic reprogramming in human cancers. Moreover, the applications of natural products and small molecule inhibitors targeting glucose metabolic reprogramming are analyzed, some clinical agents targeting glucose metabolic reprogramming and trial statuses are summarized, as well as the pros and cons of targeting glucose metabolic reprogramming for cancer therapy are analyzed. Overall, the reprogramming of glucose metabolism plays an important role in the prediction, prevention, diagnosis and treatment of human cancers. Glucose metabolic reprogramming-related targets have great potential to serve as biomarkers for improving individual outcomes and prognosis in cancer patients. The clinical innovations related to targeting the reprogramming of glucose metabolism will be a hotspot for cancer therapy research in the future. We suggest that more high-quality clinical trials with more abundant drug formulations and toxicology experiments would be beneficial for the development and clinical application of drugs targeting reprogramming of glucose metabolism.This review will provide the researchers with the broader perspective and comprehensive understanding about the important significance of glucose metabolic reprogramming in human cancers.

Complete response in patient with locally advanced lung large cell neuroendocrine carcinoma under sintilimab plus platinum-based chemotherapy: A case report.

Pulmonary large-cell neuroendocrine carcinoma (LCNEC) is an uncommon subtype of lung cancer with bleak prognosis. Its optimal treatment remains undetermined due to its malignancy. A 66-year-old man diagnosed with unresectable locally advanced LCNEC exhibited partial radiographic response to chemo-immunotherapy. He underwent salvage surgery after 4 rounds of docetaxel/nedaplatin (DP) regimen plus sintilimab, a highly selective monoclonal antibody which targets human anti-programmed death-ligand 1 (PD-L1). In addition, the pathologic examination of the excision demonstrated that there were no viable residuary tumor cells. This case indicates that neoadjuvant chemo-immunotherapy might benefit patients with locally advanced LCNEC, which deserves further investigation.

[The distribution of Chinese medicine syndrome types in primary liver cancer and their differences of the survival time: a clinical study].

OBJECTIVE: To explore the distribution of Chinese medicine (CM) syndrome types in primary liver cancer (PLC) and their differences of the survival time. METHODS: From May 2007 to March 2009, recruited were 151 PLC inpatients at Department of Tumor, Guangdong Provincial Hospital of Traditional Chinese Medicine. Their survival time were statistically calculated. Patients' average survival time and median survival time were calculated using Kaplan-Meier method. The Log-rank test was used to analyze their differences of survival time among different CM syndrome types. RESULTS: The proportion of CM syndrome types in PLC patients were ranked from high to low as follows: mutual accumulation of dampness and blood stasis syndrome [MADBSS, 43.0% (65/151)], Gan-stagnation Pi-deficiency syndrome [GSPDS, 34.4% (52/151)], qi stagnation blood stasis syndrome [QSBSS, 9.3% (14/151)], retention of damp-heat syndrome [RDHS, 8.6%(13/151)], and Gan-Shen yin deficiency syndrome [GSYDS, 4.6% (7/ 151)]. The median survival time of different CM syndrome types were ranked from longer to shorter as follows: GSPDS (14.77 months), QSBSS (6.13 months), RDHS (5.27 months), MADBSS (4.78 months), and GSYDS (0.80 months). The mean survival times were ranked from longer to shorter as follows: GSPDS (12.40 months), QSBSS (8.84 months), MADBSS (6.99 months), RDHS (7.08 months), and GSYDS (0.72 months). There was statistical difference in the difference of the survival time among different CM syndrome types (P < 0.05). CONCLUSIONS: GSPDS and MADBSS were the most common CM syndrome types in PLC patients. There was difference in the survival time between GSPDS and MADBSS/between RDHS and GSYDS. There was difference in the survival time between MADBSS and GSYDS. Patients of GSPDS might get the best prognosis, while patients of GSYDS might get the poorest prognosis.

The application of arsenic trioxide in cancer: An umbrella review of meta-analyses based on randomized controlled trials.

ETHNOPHARMACOLOGICAL RELEVANCE: Processed from natural minerals, arsenic trioxide (ATO) as an ancient Chinese medicine has been used to treat diseases for over 2000 years. And it was applied to treat acute promyelocytic leukemia (APL) since the 1970s in China. Summarizing the clinical evidence of ATO in cancer is conducive to further understanding, development, and promotion of its pharmacological research. AIM OF THE STUDY: It is the first time to comprehensively assess and summarize the evidence of ATO in cancer treatment via umbrella review. MATERIALS AND METHODS: 8 databases in English or Chinese from their inception to February 21, 2023 were searched by two reviewers separately and suitable meta-analyses (MAs) were included in this umbrella review. Their methodological quality and risk of bias were evaluated and data of outcomes was extracted and pooled again. The evidence certainty of pooled results was classified. RESULTS: 17 MAs with 27 outcomes and seven comparisons in three cancers were included in this umbrella review. However, their methodological quality was unsatisfactory with 6 MAs as low quality and 12 MAs as critically low quality. Their shortcomings were mainly focused on protocol, literature selecting, bias risk, small sample study bias, and conflicts of interest or funding. And they were all assessed as high risk in bias. It was suggested that ATO had an advantage in enhancing complete remission rate, event-free survival, and recurrence free survival and decreasing recurrence rate, cutaneous toxicity, hyper leukocyte syndrome, tretinoin syndrome, edema and hepatotoxicity in different comparisons of APL with low or moderate certainty. Besides, compared with transcatheter arterial chemoembolization (TACE) alone, ATO plus TACE also could improve objective response rate, disease control rate, survival rate (0.5, 1, 2, and 3-year) and life quality and reduce the level of alpha fetoprotein in primarily hepatocellular carcinoma with low or moderate certainty. However, no significant results were found in MM. Finally, key findings were as followed. ATO has potential broad-spectrum anticancer effects but the clinical transformation is rarely achieved. Route of administration may affect the antitumor effects of ATO. ATO can act synergistically in combination with a variety of antitumor therapies. The safety and drug resistance of ATO should be paid more attention to. CONCLUSIONS: ATO may be a promising drug in anticancer treatment although earlier RCTs have dragged down the level of evidence. However, high-quality clinical trials are expected to explore its broad-spectrum anticancer effects, wide application, appropriate route of administration, and compound dosage form.

The negative effect of concomitant medications on immunotherapy in non-small cell lung cancer: An umbrella review.

BACKGROUND: Conflicting results about the effect of concomitant medications on immunotherapy in non-small cell lung cancer (NSCLC) were reported by many meta-analyses (MAs), and the certainty of evidence linking concomitant medications with immunotherapy efficacy has not been quantified, which may cause some evidence to be misinterpreted. METHODS: Four databases including Embase, Cochrane Library, PubMed, and Web of Science were searched from inception to January 2023 in English. Based on prospective or retrospective clinical controlled trials including immunotherapy with concomitant medications or not in NSCLC, quantitative MAs reporting the efficacy of immunotherapy with binary direct comparison and enough extractable data were collected. The methodological quality, reporting quality, and risk of bias of included MAs were evaluated respectively. New meta-analyses were conducted and their evidence certainty was classified as nonsignificant, weak, suggestive, highly suggestive, or convincing. RESULTS: Fifteen MAs with 5 medications were included. After being assessed by AMSTAR-2, PRISMA, and ROBIS, the major shortcomings were focused on the registration of protocol, literature retrieval or data extraction, implementation of sensitivity analysis or evidence certainty assessment, and incomplete reporting in the section of method and result. New pooled analyses indicated that antibiotics (HR = 1.545[1.318-1.811]), steroids (HR = 1.784[1.520-2.093]), proton pump inhibitors (PPIs) (HR = 1.303[1.048-1.621]) and opioids (HR = 1.910[1.213-3.006]) could shorten overall survival (OS) in patients with NSCLC receiving immunotherapy. Besides, antibiotics (HR = 1.285[1.129-1.462]) and steroids (HR = 1.613[1.315-1.979]) were harmful to progression-free survival (PFS) in these patients significantly. No negative effect was found in nonsteroidal anti-inflammatory drugs and the objective response rate of all medications. High-level evidence suggested that using PPIs before or after the initiation of immunotherapy and using steroids during the first-course immunotherapy could weaken the OS of patients with NSCLC. Meanwhile, the negative effects of antibiotics and opioids on OS or PFS were only supported by moderate or low-level evidence. CONCLUSIONS: The concurrent usage of PPIs or steroids adversely affects the survival of patients with NSCLC receiving immunotherapy. Future investigations are required to ascertain whether these adverse effects are primarily attributed to the comorbidities or the concurrent medications.
