Relationship between post-ablation fever and prognosis in initial hepatocellular carcinoma: A 15-year multicenter, retrospective cohort study.

BACKGROUND: Fever is a common side effect following thermal ablation in patients with hepatocellular carcinoma (HCC), yet its impact on prognosis remains unclear. MATERIALS AND METHODS: This retrospective study included initial HCC patients who underwent US-guided percutaneous microwave ablation at 13 hospitals between January 2006 and February 2021. All patients were categorized into afebrile, transient low-grade fever (TLF), and prolonged or high-grade fever (PHF) groups. Primary outcomes included very early recurrence (VER) and early recurrence (ER), secondary outcomes were disease-free survival (DFS) and overall survival (OS). Fever cut-offs for VER/ER were established using restrictive cubic splines and adjusted Cox model. Survival analyses used the Kaplan-Meier method. RESULTS: A total of 1458 initial HCC patients (mean age, 59±11[SD]; 1146 men). Compared to afebrile individuals, patients with TLF (temperatures ranging 37.0-38.8°C for 1-2 d), showed independent protective effects against VER (HR, 0.73; 95% CI: 0.57,0.95; P=0.02) and ER (HR, 0.66; 95% CI: 0.54,0.81; P<0.001), however, PHF showed no differences in VER (HR, 0.99; 95% CI: 0.76,1.30; P=0.96) and ER (HR, 0.86; 95% CI: 0.69,1.07; P=0.17). With a median follow-up of 47 months (IQR:26-79), the median DFS for TLF patients was 40 months, superior to afebrile (30 mo, P=0.019) and PHF patients (33 mo, P=0.049). The 5-year OS rate for TLF patients was 73.2%, higher than afebrile (69.3%, P=0.02) and PHF patients (66.7%, P=0.03). No significant difference was found in DFS and OS between afebrile and PHF patients (P=0.90 and 0.71). Notably, TLF patients exhibited the highest lymphocyte counts increasing median 7 days after ablation (P<0.001 vs. afebrile and P=0.01 vs. PHF). CONCLUSION: Transient low-grade fever following percutaneous microwave ablation in hepatocellular carcinoma patients demonstrated protection against early recurrence, possibly attributed to the short-term activation of lymphocytes.

Monolithic integrated optoelectronic chip for vector force detection.

Sensors with a small footprint and real-time detection capabilities are crucial in robotic surgery and smart wearable equipment. Reducing device footprint while maintaining its high performance is a major challenge and a significant limitation to their development. Here, we proposed a monolithic integrated micro-scale sensor, which can be used for vector force detection. This sensor combines an optical source, four photodetectors, and a hemispherical silicone elastomer component on the same sapphire-based AlGaInP wafer. The chip-scale optical coupling is achieved by employing the laser lift-off techniques and the flip-chip bonding to a processed sapphire substrate. This hemispherical structure device can detect normal and shear forces as low as 1 mN within a measurement range of 0-220 mN for normal force and 0-15 mN for shear force. After packaging, the sensor is capable of detecting forces over a broader range, with measurement capabilities extending up to 10 N for normal forces and 0.2 N for shear forces. It has an accuracy of detecting a minimum normal force of 25 mN and a minimum shear force of 20 mN. Furthermore, this sensor has been validated to have a compact footprint of approximately 1.5 mm2, while maintaining high real-time response. We also demonstrate its promising potential by combining this sensor with fine surface texture perception in the fields of compact medical robot interaction and wearable devices.

Integrating single-cell and multi-omic approaches reveals Euphorbiae Humifusae Herba-dependent mitochondrial dysfunction in non-small-cell lung cancer.

Euphorbiae Humifusae Herba (EHH) is a pivotal therapeutic agent with diverse pharmacological effects. However, a substantial gap exists in understanding its pharmacological properties and anti-tumour mechanisms. This study aimed to address this gap by exploring EHH's pharmacological properties, identifying NSCLC therapy-associated protein targets, and elucidating how EHH induces mitochondrial disruption in NSCLC cells, offering insights into novel NSCLC treatment strategies. String database was utilized to explore protein-protein interactions. Subsequently, single-cell analysis and multi-omics further unveiled the impact of EHH-targeted genes on the immune microenvironment of NSCLC, as well as their influence on immunotherapeutic responses. Finally, both in vivo and in vitro experiments elucidated the anti-tumour mechanisms of EHH, specifically through the assessment of mitochondrial ROS levels and alterations in mitochondrial membrane potential. EHH exerts its influence through engagement with a cluster of 10 genes, including the apoptotic gene CASP3. This regulatory impact on the immune milieu within NSCLC holds promise as an indicator for predicting responses to immunotherapy. Besides, EHH demonstrated the capability to induce mitochondrial ROS generation and perturbations in mitochondrial membrane potential in NSCLC cells, ultimately leading to mitochondrial dysfunction and consequent apoptosis of tumour cells. EHH induces mitochondrial disruption in NSCLC cells, leading to cell apoptosis to inhibit the progress of NSCLC.

Identification and validation of a novel cuproptosis-related stemness signature to predict prognosis and immune landscape in lung adenocarcinoma by integrating single-cell and bulk RNA-sequencing.

Background: Cancer stem cells (CSCs) play vital roles in lung adenocarcinoma (LUAD) recurrence, metastasis, and drug resistance. Cuproptosis has provided a novel insight into the treatment of lung CSCs. However, there is a lack of knowledge regarding the cuproptosis-related genes combined with the stemness signature and their roles in the prognosis and immune landscape of LUAD. Methods: Cuproptosis-related stemness genes (CRSGs) were identified by integrating single-cell and bulk RNA-sequencing data in LUAD patients. Subsequently, cuproptosis-related stemness subtypes were classified using consensus clustering analysis, and a prognostic signature was constructed by univariate and least absolute shrinkage operator (LASSO) Cox regression. The association between signature with immune infiltration, immunotherapy, and stemness features was also investigated. Finally, the expression of CRSGs and the functional roles of target gene were validated in vitro. Results: We identified six CRSGs that were mainly expressed in epithelial and myeloid cells. Three distinct cuproptosis-related stemness subtypes were identified and associated with the immune infiltration and immunotherapy response. Furthermore, a prognostic signature was constructed to predict the overall survival (OS) of LUAD patients based on eight differently expressed genes (DEGs) with cuproptosis-related stemness signature (KLF4, SCGB3A1, COL1A1, SPP1, C4BPA, TSPAN7, CAV2, and CTHRC1) and confirmed in validation cohorts. We also developed an accurate nomogram to improve clinical applicability. Patients in the high-risk group showed worse OS with lower levels of immune cell infiltration and higher stemness features. Ultimately, further cellular experiments were performed to verify the expression of CRSGs and prognostic DEGs and demonstrate that SPP1 could affect the proliferation, migration, and stemness of LUAD cells. Conclusion: This study developed a novel cuproptosis-related stemness signature that can be used to predict the prognosis and immune landscape of LUAD patients, and provided potential therapeutic targets for lung CSCs in the future.

Integrating network pharmacology prediction and experimental investigation to verify ginkgetin anti-invasion and metastasis of human lung adenocarcinoma cells via the Akt/GSK-3ß/Snail and Wnt/ß-catenin pathway.

Introduction: Lung cancer, one of the most frequent malignancies, has a high death rate and an increased number of new cases globally. Ginkgo biloba has been used for many years in the treatment of lung cancer. Ginkgetin is the key active ingredient extracted from Ginkgo biloba. However, the mechanism by which ginkgetin inhibits the invasive metastasis of lung cancer is unclear. Methods: We used a network pharmacology approach to obtain the molecular mechanism by which ginkgetin inhibits lung cancer metastasis. Then we analyzed potential target proteins between ginkgetin and lung cancer. Finally, we validated with molecular docking and experimental validation. Results: By analyzing the intersecting genes of lung cancer and ginkgetin, there were 79 intersecting genes, which were mainly involved in the positive regulation of cell migration, with the cancer pathway being one of the most enriched pathways. The results of in vitro experiments showed that GK had a large inhibitory effect on cell invasion and metastasis of A549 and H1299. In vivo animals GK had a great inhibitory effect on metastasis of LLC. Conclusion: This study identified the potential related GK molecular targets and signaling pathways in treating human lung cancer using network pharmacological approaches. Experiments confirmed that GK inhibits the Akt/GSK-3ß/Snail and Wnt/ß-catenin cascade initiation in A549, H1299 and LLC cells, preventing metastasis. This study's results align with the hypotheses derived from the network pharmacology analysis.

Active post-transcriptional regulation and ACLY-mediated acetyl-CoA synthesis as a pivotal target of Shuang-Huang-Sheng-Bai formula for lung adenocarcinoma treatment.

BACKGROUND: New therapeutic approaches are required to improve the outcomes of lung cancer (LC), a leading cause of cancer-related deaths worldwide. Chinese herbal medicine formulae widely used in China provide a unique opportunity for improving LC treatment, and the Shuang-Huang-Sheng-Bai (SHSB) formula is a typical example. However, the underlying mechanisms of action remains unclear. PURPOSE: This study aimed to confirm the efficacy of SHSB against lung adenocarcinoma (LUAD), which is a major histological type of LC, unveil the downstream targets of this formula, and assess the clinical relevance and biological roles of the newly identified target. METHODS: An experimental metastasis mouse model and a subcutaneous xenograft mouse model were used to evaluate the anti-cancer activity of SHSB. Multi-omics profiling of subcutaneous tumors and metabolomic profiling of sera were performed to identify downstream targets, especially the metabolic targets of SHSB. A clinical trial was conducted to verify the newly identified metabolic targets in patients. Next, the metabolites and enzymes engaged in the metabolic pathway targeted by SHSB were measured in clinical samples. Finally, routine molecular experiments were performed to decipher the biological functions of the metabolic pathways targeted by SHSB. RESULTS: Oral SHSB administration showed overt anti-LUAD efficacy as revealed by the extended overall survival of the metastasis model and impaired growth of implanted tumors in the subcutaneous xenograft model. Mechanistically, SHSB administration altered protein expression in the post-transcriptional layer and modified the metabolome of LUAD xenografts. Integrative analysis demonstrated that SHSB markedly inhibited acetyl-CoA synthesis in tumors by post-transcriptionally downregulating ATP-citrate lyase (ACLY). Consistently, our clinical trial showed that oral SHSB administration declined serum acetyl-CoA levels of patients with LC. Moreover, acetyl-CoA synthesis and ACLY expression were both augmented in clinical LUAD tissues of patients, and high intratumoral ACLY expression predicted a detrimental prognosis. Finally, we showed that ACLY-mediated acetyl-CoA synthesis is essential for LUAD cell growth by promoting G1/S transition and DNA replication. CONCLUSION: Limited downstream targets of SHSB for LC treatment have been reported in previous hypothesis-driven studies. In this study, we conducted a comprehensive multi-omics investigation and demonstrated that SHSB exerted its anti-LUAD efficacy by actively and post-transcriptionally modulating protein expression and particularly restraining ACLY-mediated acetyl-CoA synthesis.

Exosomal lncRNA HOTAIR promotes osteoclast differentiation by targeting TGF-ß/PTHrP/RANKL pathway.

Bone tissue is a common metastatic site of lung cancer, and bone metastasis is characterized by abnormal differentiation and malfunction of osteoclast, and the roles of exosomes derived from lung cancer have attracted much attention. In our study, we found that the level of HOTAIR expression in A549 and H1299 exosomes was higher than those of normal lung fibrocytes. Overexpression of HOTAIR in A549 and H1299 exosomes promoted osteoclast differentiation. Furthermore, A549-Exos and H1299-Exos targeted bone tissues, and bone formation was significantly inhibited in vivo. Mechanistically, exosomal lncRNA HOTAIR promoted bone resorption by targeting TGF-ß/PTHrP/RANKL pathway.

Exosomal miR-328 originated from pulmonary adenocarcinoma cells enhances osteoclastogenesis via downregulating Nrp-2 expression.

Osseous metastases of pulmonary carcinoma and the detailed mechanisms remain unclear, and the effects of exosomes (Exos) originated from pulmonary adenocarcinoma cells in this process have received a lot of attentions. Our study revealed that the Exos secreted from A549 cells (A549-Exos) enhanced osteoclastogenesis and osseous resorption in vitro. In addition, A549-Exos showed a targeted effect on bones to enhance osseous resorption in vivo. A549-exosomal miR-328 enhanced osseous resorption via downregulating neuropilin 2 (Nrp-2) expression, and A549-Exos miR-328 inhibitors suppressed osseous resorption in vivo. Therefore, A549-exosomal miR-328 enhances osteoclastogenesis via downregulating Nrp-2 expression, thus A549-Exos miR-328 inhibitors can be used as a potential nanodrug for treating osseous metastases.

Feiyanning downregulating CXCLs/CXCR2 axis to suppress TANs infiltration in the prevention of lung cancer metastasis.

ETHNOPHARMACOLOGICAL RELEVANCE: Tumor-associated neutrophils (TANs) play an important role in tumor metastasis. The Traditional Chinese medicine (TCM) Feiyanning (FYN) has been clinically proven to effectively prevent the recurrence and metastasis of lung cancer, improve immunity, and prolong the survival period of lung cancer patients. However, its anti-metastatic immune mechanism has not been fully elucidated. To this end, we studied the mechanism of FYN's regulation of neutrophils infiltration in the tumor microenvironment (TME). AIM OF THE STUDY: To explore the anti-metastatic mechanism of FYN from the perspective of anti-immunosuppressive phenotype neutrophils infiltration in the TME. MATERIALS AND METHODS: TCM network pharmacological analysis was used to predict Feiyanning effective target. Flow cytometry was used to detect the proportion of immune cell subsets in the TME. Lung metastases were investigated in C57 mice by tail vein injection. Protein expression was evaluated by immunohistochemistry and Western blot. Gene expression was evaluated by qRT-PCR. RESULTS: FYN could reshape the tumor immune microenvironment. It prevents Tregs, M2 macrophages, and neutrophils infiltration, as well as recruits T cells, NK cells, and DCs, and improves DCs activation. In addition, FYN could regulate the polarization of TANs, inhibit the infiltration of neutrophils with an immunosuppressive phenotype, downregulate CXCLs/CXCR2 axis and inhibitory factors like Arg-1 and TGF-ß, and up-regulate the immune effector molecule ICAM-1. Furthermore, FYN increases anti-tumor immune effects in the TME to prevent tumor cells from spreading to the lungs. CONCLUSION: This study clarifies the potential mechanism of FYN in regulating neutrophils infiltration and anti-metastasis. FYN may regulate neutrophils infiltration in the TME by regulating CXCLs/CXCR2 axis.

Construction of circRNA-miRNA-mRNA network and identification of novel potential biomarkers for non-small cell lung cancer.

BACKGROUND: The underlying circular RNAs (circRNAs)-related competitive endogenous RNA (ceRNA) mechanisms of pathogenesis and prognosis in non-small cell lung cancer (NSCLC) remain unclear. METHODS: Differentially expressed circRNAs (DECs) in two Gene Expression Omnibus datasets (GSE101684 and GSE112214) were identified by utilizing R package (Limma). Circinteractome and StarBase databases were used to predict circRNA associated-miRNAs and mRNAs, respectively. Then, protein-protein interaction (PPI) network of hub genes and ceRNA network were constructed by STRING and Cytoscape. Also, analyses of functional enrichment, genomic mutation and diagnostic ROC were performed. TIMER database was used to analyze the association between immune infiltration and target genes. Kaplan-Meier analysis, cox regression and the nomogram prediction model were used to evaluate the prognostic value of target genes. Finally, the expression of potential circRNAs and target genes was validated in cell lines and tissues by quantitative real-time PCR (qRT-PCR) and Human Protein Atlas (HPA) database. RESULTS: In this study, 15 DECs were identified between NSCLC tissues and adjacent-normal tissues in two GEO datasets. Following the qRT-PCR corroboration, 7 DECs (hsa_circ_0002017, hsa_circ_0069244, hsa_circ_026337, hsa_circ_0002346, hsa_circ_0007386, hsa_circ_0008234, hsa_circ_0006857) were dramatically downregulated in A549 and SK-MES-1 compared with HFL-1 cells. Then, 12 circRNA-sponged miRNAs were screened by Circinteractome and StarBase, especially, hsa-miR-767-3p and hsa-miR-767-5p were significantly up-regulated and relevant to the prognosis. Utilizing the miRDB and Cytoscape, 12 miRNA-target genes were found. Functional enrichment, genomic mutation and diagnostic analyses were also performed. Among them, FNBP1, AKT3, HERC1, COL4A1, TOLLIP, ARRB1, FZD4 and PIK3R1 were related to the immune infiltration via TIMER database. The expression of ARRB1, FNBP1, FZD4, and HERC1 was correlated with poor overall survival (OS) in NSCLC patients by cox regression and nomogram. Furthermore, the hub-mRNAs were validated in cell lines and tissues. CONCLUSION: We constructed the circRNA-miRNA-mRNA network that might provide novel insights into the pathogenesis of NSCLC and reveal promising immune infiltration and prognostic biomarkers.

Chinese herbal medicine Feiyanning cooperates with cisplatin to enhance cytotoxicity to non-small-cell lung cancer by inhibiting protective autophagy.

ETHNOPHARMACOLOGICAL RELEVANCE: Feiyanning (FYN), the Chinese herbal medicine (CHM), has been used to manage non-small cell lung cancer (NSCLC) for the past 23 years. Chemotherapeutic drugs can induce autophagy in cancer cells to protect themselves from death. However, FYN can inhibit the protective autophagy in cancer cells. We investigated the biological mechanisms on the synergistic effects of FYN combined with chemotherapy in lung cancer cells. MATERIALS AND METHODS: We analyzed the effective chemical components for the quality control of FYN using the UPLC-Q-TOF-MS.The cell proliferation ability was detected by the cell counting kit-8 (CCK-8) and colony formation. The cell apoptosis was determined with Flow cytometry. Expression of important differential proteins were detected by western blot. Autophagy structure was observed by TEM (Tansmission electron microscopy). Tandem mCherry-EGFP-LC3B immunofluorescence was used to measure autophagic flux. RESULTS: Both FYN and cisplatin significantly induced apoptosis and inhibited cell proliferation in A549 cells. FYN reduced cell viability and increased apoptotic cell populations less effectively than cisplatin. FYN cooperated with cisplatin suppressed the cell viability, colony formation, as well as increased the cell apoptosis rate, and the expression of cleaved caspase-3 and PARP. FYN inhibited autophagy in A549 cells, which characterized by the decrease of autophagosome formation, lysosomal fusion, LC3B-II accumulation and SQSTM1 degradation, down-regulation of ATG5 and ATG7. Protective autophagy in A549 cells was induced by cisplatin. Suppression of the autophagic response using chloroquine (CQ) which is autophagy inhibitor improved the ability of cisplatin to kill cancer cells, as did FYN combined with cisplatin. CONCLUSION: In summary, we revealed that the synergistic mechanism of FYN and cisplatin is that FYN inhibited the protective autophagy induced by cisplatin in A549 cells.

The HOTAIR lncRNA: A remarkable oncogenic promoter in human cancer metastasis.

Long non-coding RNA (lncRNA) is a new type of non-coding RNA that has an important regulatory influence on several human diseases, including cancer metastasis. HOX antisense intergenic RNA (HOTAIR), a newly discovered lncRNA, has an important effect on tumour proliferation, migration and metastasis. HOTAIR regulates cell proliferation, changes gene expression, and promotes tumour cell invasion and migration. However, its molecular mechanism of action remains unknown. The present review summarizes the molecular mechanism and role of HOTAIR in tumour invasion and metastasis, discusses the association between HOTAIR and tumour metastasis through different pathways, such as the transforming growth factor ß, Wnt/ß-catenin, PI3K/AKT/MAPK and vascular endothelial growth factor pathways, emphasizes the function of HOTAIR in human malignant tumour metastasis and provides a foundation for its application in the diagnosis, prognosis and medical treatment of various tumours.

Comparative molecular profiling of distant metastatic and non-distant metastatic lung adenocarcinoma.

Most lung cancer deaths are caused by a distant disseminated disease rather than primary tumors. Understanding the biology behind distant metastasis (DM) is crucial for the effective prediction and reduction of recurrence rates. Genome-wide analysis of the tumor provides a new way to explore the pathogenesis and molecular diagnosis of metastasis in lung adenocarcinoma. In our study, a total of 215 eligible lung adenocarcinoma patients were enrolled. The DNA was extracted from formalin-fixed paraffin-embedded (FFPE) samples from the primary tumors of these patients. Comprehensive molecular profiling was performed using a panel covering the exome of lung cancer-associated driver genes based on targeted next-generation sequencing. Tumor gene alterations were analyzed to investigate the differences in molecular features between lung adenocarcinomas with or without DM. Patients with DM of lung adenocarcinoma had significantly more variations in overall copy number (defined as Copy Number Alteration (CNA) load and Copy Number Instability (CNI) score). Interestingly, the study of the relationship between copy number variation and other molecular features verified that the degree of copy number variation has a positive correlation with mutations of DNA damage repair pathway (DDR). Thus, the additional analysis further revealed that metastatic patients accumulated more mutations in the DDR pathway, suggesting that impaired function of the DDR pathway and copy number variations play important roles in the invasion process of cancer cells. A comprehensive genetic analysis of lung adenocarcinoma revealed significant genomic changes between DM and non-DM patients. This finding may shed new light on the elucidation of lung cancer invasion mechanisms, and provide potential predictors for metastatic lung cancer.

ZEB1 Promotes Chemoresistance to Cisplatin in Ovarian Cancer Cells by Suppressing SLC3A2.

Ovarian cancer is one of the deadliest gynecological malignancies in women. Chemoresistance has been a major obstacle for ovarian cancer treatment. Zinc finger E-box-binding homeobox 1 (ZEB1) is an important regulator of tumor development in various types of cancer. Abnormal expression of SLC3A2 (CD98hc), a type 2 transmembrane cell surface molecule, has been described in several cancers. This study was designed to investigate the role of ZEB1 and SLC3A2 in the chemoresistance to cisplatin in ovarian cancer cells. We found that ZEB1 was increased in cisplatin-resistant SKOV3/DPP cells. Downregulation of ZEB1 significantly decreased cell viability in response to cisplatin, increased cis-platin-induced apoptosis, and decreased migration and invasion in the presence of cisplatin. In addition, downregulation of ZEB1 decreased the volume and weight of implanted tumors. SLC3A2 was decreased in cisplatin-resistant SKOV3/DPP cells. Upregulation of SLC3A2 significantly decreased cell viability in response to cisplatin, increased cisplatin-induced apoptosis, and decreased migration and invasion in the presence of cisplatin. Moreover, upregulation of SLC3A2 decreased the volume and weight of implanted tumors. Downregulation of ZEB1 resulted in a significant increase of SLC3A2 expression. Moreover, downregulation of SLC3A2 significantly inhibited ZEB1 knockdown-mediated inhibition of cisplatin-resistance. ZEB1-mediated regulation of SLC3A2 was involved in the chemoresistance to cisplatin in ovarian cancer cells. Overall, we provide new insights into the mechanism of chemoresistance to cisplatin in ovarian cancer cells. ZEB1/SLC3A2 may be promising therapeutic targets for enhancement of the sensitivity of ovarian cancer cells to cisplatin-mediated chemotherapy.

Association of One-Carbon Metabolism-Related Vitamins (Folate, B6, B12), Homocysteine and Methionine With the Risk of Lung Cancer: Systematic Review and Meta-Analysis.

Background: Studies on serum one-carbon metabolism factors (folate, B6, B12, homocysteine, and methionine) with lung cancer (LC) risk have produced inconsistent results. We aimed to systematically evaluate the association between them. Methods: This study was reported in accordance with the PRISMA Statement and was registered with PROSPERO (no. CRD42018086654). Relevant studies were searched in PubMed, Embase, MEDLINE, and CNKI up to February 2018. Random-effects models were used to estimate the pooled standardized mean differences (SMD) or odds ratios (OR), as well as their 95% confidence interval (CI). Sensitivity and subgroup analysis were performed to identify the source of heterogeneity. Publication bias was also assessed. Results: A total of 14 articles (8,097 patients) were included. The concentration of serum folate and vitamin B6 of LC patients were lower than the controls [SMD -0.53, 95% CI (-0.70, -0.35), p = 0.001 and SMD -0.28, 95%CI (-0.53, -0.02), p = 0.001, respectively]. While the concentration of homocysteine of the cases was higher than the controls [SMD 0.41, 95% CI (0.24, 0.59), p = 0.001]. However, there were no significant differences between LC patients and the controls in terms of vitamin B12 and methionine [SMD -0.09, 95% CI (-0.27, 0.09), p = 0.202 and SMD -0.13, 95% CI (-0.36, 0.10), p = 0.001]. Subgroup analysis showed that these results were more significant in Europe, Asia, former and current smokers, and the male population (p-value < 0.05). Conclusions: Serum folate and vitamin B6 might be protective factors against lung carcinogenesis and homocysteine could contribute to LC risk.

The overall globe salvage rate is 78.7% (Group D (84.2%), and Group E (69.6%) and followed-up. Short-term ocular complications include eyelid edema (15 cases), ptosis (5 cases), forehead congestion (3 cases), retina hemorrhage (5 cases), choroid atrophy (2 cases), phthisis bulbi (1 case), bradycardia and hypotension during the procedure (7cases), myelosuppressions (6 cases), and nausea and vomiting (5cases).IAC is safe and effective for the treatment of unilateral advanced intraocular RB with a very low complication rate.

Treatment of Advanced Non-small-Cell Lung Cancer with Qi-Nourishing Essence-Replenishing Chinese Herbal Medicine Combined with Chemotherapy.

BACKGROUND: To evaluate the effect of qi-nourishing essence-replenishing Chinese herbal medicine combined with chemotherapy in survival of advanced non-small-cell lung cancer(NSCLC) patients with essence and qi deficiency. METHODS: A prospective multi-centered randomized controlled study was conducted, and 266 advanced NSCLC patients were enrolled. 126 patients in control group received Vinorelbine plus cisplatin(NP) chemotherapy combined with symptom-oriented Chinese herbs medication(without qi-nourishing essence-replenishing herbs);140 patients in experimental group received NP chemotherapy combined with qi-nourishing essence-replenishing Chinese herbal medication(Kangliu Zengxiao Decoction and modified Feiyanning Decoction, during and after chemotherapy respectively). RESULTS: One patient in control and 2 in experimental group were excluded for failure to complete two cycles of chemotherapy. During follow-up, 17 and 7 patients in control and experimental group were excluded respectively(4 and 4 for taking Gefetinib after disease progression, 4 and 2 for receiving other chemotherapeutic regimens, 9 and 1 for lost to follow-up). 239 patients were included in the final analysis (131 in experimental group and 108 in control). Median overall survival in experimental group was significantly longer than control group (14.87vs.12.97 months,P = 0.027). In experimental and control group, 1-year, 3-year, 5-year, 7-year, and 9-year survival rates were 57% vs. 53%, 17% vs. 8%, 10% vs. 2%, 6% vs. 0%, and 6% vs. 0%, respectively. CONCLUSION: Qi-nourishing essence-replenishing Chinese herbal medicine combined with chemotherapy improves survival of advanced NSCLC patients with essence and qi deficiency.
