RESUMO
OBJECTIVE: To observe the effects of moxibustion at "Mingmen" (GV 4) and "Guanyuan" (CV 4) on immune function and intestinal flora in healthy rats, thereby investigating the underlying mechanism of moxibustion on immune function. METHODS: Twenty 8-week-old SD rats were randomly divided into a young blank group and a young moxibustion group, with 10 rats in each group. Similarly, twenty 8-month-old SD rats were randomly divided into a middle-aged blank group and a middle-aged moxibustion group, with 10 rats in each group. The rats in the two moxibustion groups received moxibustion at "Mingmen" (GV 4) and "Guanyuan" (CV 4), 15 min per session, once daily, five times a week, for a total of four months. The rats in the two blank groups were fed under normal conditions. After the intervention, thymus and spleen indexes were calculated; the morphology of thymus and spleen tissues was observed using HE staining; the flow cytometry was used to detect the expression of CD and CD T lymphocytes and the CD/CD ratio was calculated; ELISA was used to measure the serum levels of tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-17 (IL-17); 16S rRNA high-throughput sequencing was used to analyze the intestinal flora. Additionally, the correlation between the relative abundance of intestinal flora and serum levels of TNF-α, IFN-γ, IL-6, IL-10 and IL-17 was analyzed. RESULTS: Compared with the young blank group, the young moxibustion group exhibited an increase in the cortical area of thymus tissue with tighter lymphocyte arrangement; compared with the middle-aged blank group, the middle-aged moxibustion group showed an increase in thymus index (P<0.05) and an increase in the cortical area of thymus tissue. There were no significant differences in spleen index between the 2 moxibustion groups and the 2 blank groups (P>0.05). There were no significant differences in the expression of CD, CD, and CD/CD ratio between the 2 moxibustion groups and the corresponding blank groups (P>0.05). Compared with the young blank group, the young moxibustion group had elevated IL-6 level (P<0.05); compared with the middle-aged blank group, the middle-aged moxibustion group had decreased IL-10 and IL-17 levels (P<0.05). Compared with the young blank group, the young moxibustion group exhibited increased Sobs index, Ace index, and Chao index (P<0.01, P<0.05), as well as increased relative abundance of Spirochaetota, Treponema, Turicibacter, Rikenellaceae_RC9_gut_group (P<0.05), and decreased relative abundance of Dubosiella (P<0.05). Compared with the middle-aged blank group, the middle-aged moxibustion group had increased relative abundance of Spirochaetota, Treponema, norank_f_Peptococcaceae (P<0.05), and decreased relative abundance of Proteobacteria, Allobaculum, and Faecalibaculum (P<0.05). Correlation analysis revealed that relative abundance of Eubacterium_xylanophilum_group and unclassified _f_Lachnospiraceae was negatively correlated with serum TNF-α level (r=-0.39, P=0.03; r=-0.24, P=0.04), while relative abundance of norank_f_norank_o_Clostridia_UCG-014 and Lactobacillus was positively correlated with serum TNF-α level (r=0.37, P=0.04; r=0.43, P=0.02). The relative abundance of Roseburia and Monoglobus was negatively correlated with serum IFN-γ level (r=-0.40, P=0.02; r=-0.44, P=0.01), while relative abundance of Lactobacillus was positively correlated with serum IL-10 level (r=0.43, P=0.02). CONCLUSION: Moxibustion could improve immune function in healthy rats, and its mechanism may be related to the regulation of relative abundance of intestinal flora.

Ammonium promotes rice P uptake and reutilization better than nitrate, under P starvation conditions; however, the underlying mechanism remains unclear. In this study, ammonium treatment significantly increased putrescine and ethylene content in rice roots under P deficient conditions, by increasing the protein content of ornithine decarboxylase and 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase compared with nitrate treatment. Ammonium treatment increased rice root cell wall P release by increasing pectin content and pectin methyl esterase (PME) activity, increased rice shoot cell membrane P release by decreasing phosphorus-containing lipid components, and maintained internal P homeostasis by increasing OsPT2/6/8 expression compared with nitrate treatment. Ammonium also improved external P uptake by regulating root morphology and increased rice grain yield by increasing the panicle number compared with nitrate treatment. The application of putrescine and ethylene synthesis precursor ACC further improved the above process. Our results demonstrate for the first time that ammonium increases rice P acquisition, reutilization, and homeostasis, and rice grain yield, in a putrescine- and ethylene-dependent manner, better than nitrate, under P starvation conditions.

OBJECTIVES: We performed an up-to-date meta-analysis to quantify the overall incidence and risk of severe adverse events (AEs) associated with T-DM1 in patients with breast cancer. METHODS: Pubmed, Embase, and oncology conference proceedings were searched for relevant studies. Data were extracted to calculate the summary incidence rate and relative risk (RR) of grade ≥3 AEs. RESULTS: A total of 5,045 patients from 7 RCTs were included in the meta-analysis. The use of T-DM1 was associated with an increased risk of severe thrombocytopenia (RR 10.66, 95% CI 3.23-35.18, P < 0.001), anemia (RR 1.68, 95% CI 1.15-2.44, P = 0.007), elevated ALT (RR 2.67, 95% CI 1.60-4.47, P < 0.001), and AST (RR 3.76, 95% CI 1.45-9.78, P = 0.007). In addition, the use of T-DM1 can increase the risk of severe hypertension (RR 1.59, 95% CI 1.03-2.45, P = 0.037) and peripheral sensory neuropathy (RR 8.13, 95% CI 1.89-35.03, P = 0.005). CONCLUSIONS: Treatment with T-DM1 increases the risk of severe hematologic toxicities, hepatotoxicity, hypertension, and peripheral sensory neuropathy in patients with breast cancer, while the overall incidence of these AEs is low.

As the leading cause of cancer death, lung cancer seriously endangers human health and quality of life. Although many studies have reported the intestinal microbial composition of lung cancer, little is known about the interplay between intestinal microbiome and metabolites and how they affect the development of lung cancer. Herein, we combined 16S ribosomal RNA (rRNA) gene sequencing and liquid chromatography-mass spectrometry (LC-MS) technology to analyze intestinal microbiota composition and serum metabolism profile in a cohort of 30 lung cancer patients with different stages and 15 healthy individuals. Compared with healthy people, we found that the structure of intestinal microbiota in lung cancer patients had changed significantly (Adonis, p = 0.021). In order to determine how intestinal flora affects the occurrence and development of lung cancer, the Spearman rank correlation test was used to find the connection between differential microorganisms and differential metabolites. It was found that as thez disease progressed, L-valine decreased. Correspondingly, the abundance of Lachnospiraceae_UCG-006, the genus with the strongest association with L-valine, also decreased in lung cancer groups. Correlation analysis showed that the gut microbiome and serum metabolic profile had a strong synergy, and Lachnospiraceae_UCG-006 was closely related to L-valine. In summary, this study described the characteristics of intestinal flora and serum metabolic profiles of lung cancer patients with different stages. It revealed that lung cancer may be the result of the mutual regulation of L-valine and Lachnospiraceae_UCG-006 through the aminoacyl-tRNA biosynthesis pathway, and proposed that L-valine may be a potential marker for the diagnosis of lung cancer.

Hydrogen sulfide (H2S) improves aluminum (Al) resistance in rice, however, the underlying mechanism remains unclear. In the present study, treatment with 30-µM Al significantly inhibited rice root growth and increased the total Al content, apoplastic and cytoplasm Al concentration in the rice roots. However, pretreatment with NaHS (H2S donor) reversed these negative effects. Pretreatment with NaHS significantly increased energy production under Al toxicity conditions, such as by increasing the content of ATP and nonstructural carbohydrates. In addition, NaHS stimulated the AsA-GSH cycle to decrease the peroxidation damage induced by Al toxicity. Pretreatment with NaHS significantly inhibited ethylene emissions in the rice and then inhibited pectin synthesis and increased the pectin methylation degree to reduce cell wall Al deposition. The phytohormones indole-3-acetic and brassinolide were also involved in the alleviation of Al toxicity by H2S. The transcriptome results further confirmed that H2S alleviates Al toxicity by increasing the pathways relating to material and energy metabolism, redox reactions, cell wall components, and signal transduction. These findings improve our understanding of how H2S affects rice responses to Al toxicity, which will facilitate further studies on crop safety.

Emerging evidence greatly implicates that microRNA-450a (miR-450a) plays an essential role in cancer pathobiology. While the pathological role of miR-450a in breast carcinogenesis remains enigmatic. Herein, we showed that miR-450a was lowly expressed in breast cancer cell lines compared with normal, and low miR-450a expression was associated with poor survival in patients with breast cancer. We revealed that miR-450a mimic transfected breast cancer cells (T47D and BT474) exhibited attenuated capacities of proliferation, migration, and invasion in vitro, and miR-450a suppressed T47D cell growth in a xenograft tumor model. Mechanistically, cAMP response element-binding protein 1 (CREB1) was negatively targeted by miR-450a, and CREB1 deletion mimicked the effects of miR-450a mimic treatment. Bioinformatics analysis further revealed that elevated expression of CREB1 correlated with poor prognosis in patients with breast cancer and miR-450a level was negatively correlated with CREB1 level in breast cancer. Additionally, miR-450a inhibited the phosphorylation of phosphatidylinositol 3-kinase/V-akt murine thymoma viral oncogene homolog (PI3K/AKT) and the activities of matrix metalloproteinase-2/9 (MMP-2/9). The following rescue assay indicated that CREB1 was implicated in the anti-tumoral effect of mR-450a in breast carcinoma. All these observations disclosed that miR-450a negatively regulates the growth and metastatic property of breast carcinoma cells.

The present study analyzed the efficacy evaluation indexes of the randomized controlled trials(RCTs) of Chinese medi-cine in the treatment of rheumatic heart disease to lay the foundation for the construction of the corresponding core outcome index set. Clinical RCTs with a definite diagnosis of rheumatic heart disease were retrieved from CNKI, Wanfang, VIP, Sino Med, Pub Med, EMbase, and Cochrane Library from January 1, 2010, to December 31, 2020. Thirty-five RCTs were included, involving 3 314 patients and 41 efficacy evaluation indexes, which covered seven domains [traditional Chinese medicine(TCM) symptoms/syndromes, symp-toms/signs, physical and chemical examination, quality of life, long-term prognosis, economic evaluation, and safety events]. Physi-cal and chemical examination(56. 91%) and symptoms/signs(29. 27%) were the more frequently applied. The number of indexes used in a single trial ranged from 1 to 15, with an average of 4. The measurement time points of the top five indexes in the frequency of use were as follows: total response rate was reported at five measurement time points, ranging from 14 days to 6 months; left ventri-cular ejection fraction was measured at eight time points ranging from 5 days to 6 months; left ventricular end systolic diameter was measured at six time points, ranging from 5 days to 6 months; interleukin-2(IL-2) and tumor necrosis factor-α(TNF-α) were repor-ted 28 days after treatment. At present, there are many problems in the efficacy outcome indexes of RCTs in the treatment of rheumatic heart disease with TCM, such as large difference in quantity, unclear primary and secondary indexes, unreasonable selection of " surro-gate indexes", insufficient attention to long-term prognostic indexes and safety event indexes, non-standard application of composite in-dexes, long measurement period, and lack of TCM characteristics. It is urgent to establish the core outcome set for TCM treatment of rheumatic heart disease.

OBJECTIVE: To explore the effect of mmu-circRNA_016901 on the regulation of radiation injury of bone marrow stem cells and its mechanism. METHODS: Bone marrow stem cells were exposed to different dose of X-ray, then the expression level of mmu-circRNA_016901 in bone marrow cells treated with different doses of X-ray was detected. The luciferase reporter gene assay was used to confirm that miRNA1249-5p is the target of mmu-circRNA_016901, and RNA Binding Protein Immunoprecipitation was used to confirm that TGF-ß3 is the targeted on miRNA1249-5pï¼the expression of TGF-ß3 and cell proliferation were detected after the expression of mmu-circRNA_01690 was regulated. RESULTS: When the irradiation doseï¼6 Gy, there were significant difference in the expression of mmn-circRNA-016901 after the bone marrow mesenchymal stem cells were treated by different doses of irradiation, which showed a statistically significant (Pï¼0.05). The luciferase reporter gene detection and co-immunoprecipitation experiments confirmed that Mmu-circRNA_016901 could binds to miRNA1249-5p specifically, and overexpression of mmu-circRNA_016901 could regulate miRNA1249-5p negatively, which resulted in a significant increase in TGF-ß3 expression and promoting of cell proliferation. CONCLUSION: mmu-circRNA_016901 affects the expression of TGF-ß3 through miRNA1249-5p, and thus participates in the regulation of the radiation damage mechanism of bone marrow mesenchymal stem cells.

Rifampicin is a common antibiotic used in human and veterinary medicine to treat tuberculosis and other diseases caused by numerous pathogenic bacteria. However, the excessive or improper use of rifampicin usually leads to a series of problems, including bacterial resistance, excessive drug-resistance and water pollution. Thus, it is of great importance to develop selective and sensitive assays for monitoring rifampicin in biological systems. In this study, we designed a fluorescence "turn-off" strategy for the trace detection of rifampicin based on a glutathione-stabilized copper nanoclusters (GSH-Cu NC) sensor. In an aqueous solution, the fluorescence of the GSH-Cu NCs at 632 nm can be quenched effectively and selectively by rifampicin due to the inner-filter effect (IFE) of fluorescence mechanism. Distinctively, this GSH-Cu NC sensor exhibited excellent fluorescence sensing capability for the trace detection of rifampicin with a very low limit of detection (LOD) of 16 pM in a wide linear range from 50 to 10 000 pM. It is not only more sensitive than the other methods previously reported for the detection of rifampicin, but also has an outstanding selectivity and strong anti-interference in complex samples. Furthermore, the as-developed GSH-Cu NCs were also successfully applied to determine rifampicin in different real samples with quantitative spike recoveries ranging from 97% to 105%.

Aluminum (Al3+ ) toxicity in acidic soils limits crop productivity worldwide. In this study, we found that putrescine (PUT) significantly alleviates Al toxicity in rice roots. The addition of 0.1 mM PUT promoted root elongation and reduced the Al content in the root apices of Nipponbare (Nip) and Kasalath (Kas) rice under Al toxicity conditions. Exogenous treatment with PUT reduced the cell wall Al content by reducing polysaccharide (pectin and hemicellulose) levels and pectin methylesterase (PME) activity in roots and decreased the translocation of Al from the external environment to the cytoplasm by downregulating the expression of OsNRAT1, which responsible to encode an Al transporter protein Nrat1 (Nramp aluminum transporter 1). The addition of PUT under Al toxicity conditions significantly inhibited ethylene emissions and suppressed the expression of genes involved in ethylene biosynthesis. Treatment with the ethylene precursor 1-aminocylopropane-1-carboxylic acid (ACC) significantly improved ethylene emission, inhibited root elongation, increased the Al accumulation in root tips and the root cell wall, and increased cell wall pectin and hemicellulose contents in both rice cultivars under Al toxicity conditions. The ethylene biosynthesis antagonist aminoethoxyvinylglycine (AVG, inhibitor of the ACC synthase) had the opposite effect and reduced PME activity. Together, our results show that PUT decreases the cell wall Al contents by suppressing ethylene emissions and decreases the symplastic Al levels by downregulating OsNRAT1 in rice.

When boron (B) deficiency and aluminum (Al) toxicity co-exist in acidic soils, crop productivity is limited. In the current study, we found that 3⯵M of B pretreatment significantly enhances rice root elongation under Al toxicity conditions. Pretreatment with B significantly decreases the deposition of Al in rice apoplasts, suppresses the synthesis of cell wall pectin, inhibits cell wall pectin methylesterase (PME) activity and its gene expression, and increases the expression of OsSTAR1 and OsSTAR2, which are responsible for reducing the Al content in the cell walls. In addition, B pretreatment significantly increases OsALS1 expression, thereby facilitating the transfer of Al from the cytoplasm to the vacuoles. However, B pretreatment had no effect on Al uptake and citric acid secretion. Pretreatment with B significantly increases the activity of ascorbate peroxidase (APX), peroxidase (POD), and catalase (CAT), thus increasing the elimination rate of H2O2 in rice roots. Co-treatment using B and H2O2 does not increase root growth under Al toxicity conditions; it also improves pectin synthesis, enhances PME activity, and increases Al deposition in root cell walls. However, the co-treatment of B and H2O2 scavenger 4-hydroxy-TEMPO has an opposite effect. The above results indicate that applying B fertilizers in acidic soil can help decrease the side effects of Al toxicity on rice growth.

The study aimed to explore the in vivo immunoregulatory function of Grifola frondosa polysaccharide( GFP) on animal disease models. Databases of PubMed,Embase,Web of Scinece,CNKI,CBM and Wan Fang Data were searched from the date of their establishment to February 2018. Two reviewers independently screened included studies and evaluated their quality by using SYRCLE's risk of bias tool. R software was used to analyze the data. Finally,20 animal experiment studies were included. According to Metaanalysis. For cellular immunity,GFP could effectively enhance the proliferation of effect or T cells,natural killer cells and macrophages in mice. The percentage of CD4+T cells( MD = 1. 89,95% CI [0. 94,2. 83],P < 0. 000 1),CD8+T cells( MD = 8. 46,95% CI[5. 93,11. 00],P<0. 000 1),NK cells( MD= 2. 67,95% CI [0. 23,5. 11],P= 0. 03),and macrophages( MD= 14. 09,95% CI[0. 84,27. 34],P= 0. 04) were all higher than those in control group. For humoral immunity,GFP could increase the secretion of TNF-α and INF-Î³ï¼ The secretion of TNF-α( SMD = 15. 92,95% CI [9. 07,22. 76],P<0. 000 1) and INF-γ( SMD = 5. 34,95% CI[3. 42,7. 26],P<0. 000 1) were all higher than those in control group. In conclusion,GFP could regulate immunologic function by enhancing the proliferation activity of immune cells( CD4+T cells,CD8+T cells,NK cells and macrophages) and the secretion of immune factors( TNF-α and INF-γ) ï¼ However,it is necessary to further standardize the selection of specific surface markers of immune cells and the administration of GFP,in order to reduce the heterogeneity among the studies. At the same time,more attention shall be paid to experimental design,implementation and full report,especially to the establishment and implementation of animal experimental registration system,so as to improve the transparency and quality of the whole process of animal experimental research,enhance the value of basic research ultimately,and provide a reliable theoretical basis for the transformation of basic research into clinical research.

To mainly analyze the prescription rules of Chinese herbal drugs for radiation induced lung injury, optimize the prescriptions, and provide a reference for the clinical treatment of radiation induced lung injury. The major Chinese databases CNKI, CBM and Wanfang data were searched to obtain the literature on Chinese herbal drugs for radiation induced lung injury. BICOMS 2 software was used to extract and collect all Chinese herbal drugs information and generate the co-occurrence matrix; NetDraw and Gcluto software were then used to make network map and visualization matrix for analysis. A total of 552 articles (19 types and 304 Chinese herbal drugs) were included. Ophiopogon japonicus had the highest frequency (229 times), followed by Astragalus membranaceus(181 times), Glycyrrhiza uralensis (166 times), and Scutellaria baicalensis (150 times). After the classification of efficacy, deficiency-supplementing medicinal (69 kinds of Chinese herbs), heat-clearing medicine (51 kinds of Chinese herbs) and phlegm cough medicine (42 kinds of Chinese herbs) accounted for 53.29% of all the Chinese herbs, acting in the main position. After the prescription analysis for the top 25 herbal prescriptions, six main structures of common prescriptions were found for the treatment of radiation induced lung injury. There are many kinds of Chinese herbal drugs for the treatment of radiation induced lung injury in clinical application. In the future, researchers can mainly focus on Ophiopogon japonicus etc. as the main drugs, combine with other high-frequency Chinese herbal drugs found in this study, or directly refer to the main structures of commonly used prescriptions found in this analysis.

BACKGROUND: This study was performed to assess the efficacy and feasibility of definitive chemoradiotherapy consisting of weekly doses of combined paclitaxel and carboplatin concurrent with radiation therapy, followed by 2 cycles of consolidation chemotherapy for advanced esophageal carcinoma. METHODS: Eligibility criteria included local, advanced, newly diagnosed and postoperative local regional lymph node metastasis; Eastern Cooperative Oncology Group (ECOG) score ≤ 2; and adequate organ function. Patients received concurrent chemoradiation therapy consisting of radiotherapy (50.4 Gy/28 Fx or 61.2 Gy/34 Fx) and concurrent paclitaxel (50 mg/m2) and carboplatin (area under the curve, AUC = 2) on days 1, 8, 15, 22 and 29. The two-cycle consolidation chemotherapy protocol was paclitaxel (175 mg/m2) plus carboplatin (AUC = 5) administered on days 57 and 85, after concurrent chemoradiotherapy. RESULTS: Between August 2013 and February 2015, 65 patients with oesophageal carcinoma were enrolled in the study; 34 (52.3%) were newly diagnosed and 31 (47.6%) had postoperative local regional lymph node metastasis. The median overall survival time was 21.7 months (95% confidence interval [CI] 16.7-26.6), and the median progression-free survival time was 12.1 months (95% CI 9.0-15.3). A total of 96.9% (63/65) and 67.6% (44/65) patients completed ≥5 cycles and all 7 cycles of chemotherapy, respectively. A total of 93.8% (61/65) patients completed radiation therapy. The 1- and 2-year overall survival rates were 73.7 and 42.0%, respectively. The 1- and 2-year progression-free survival rates were 50.6 and 31.1%, respectively. Grade 3-4 toxicity during chemoradiotherapy included neutropenia (24.5%), thrombocytopenia (4.6%), fatigue (1.5%), anaemia (1.5%), radiation dermatitis (1.5%), pneumonitis (1.5%), oesophagitis (4.6%) and vomiting (1.5%). CONCLUSIONS: In patients with locally advanced oesophageal cancer, the combination of weekly doses of paclitaxel and carboplatin was well tolerated and produced comparable results. A three-arm randomised phase III trial (NCT02459457) comparing paclitaxel in combination with cisplatin, carboplatin or 5-fluorouracil with concurrent radiotherapy is on-going at our hospital.

BACKGROUND: Increasing evidences have shown that long noncoding RNAs (lncRNAs) are involved in cancer diagnosis and prognosis. However, the overall diagnostic accuracy of lncRNAs for hepatocellular carcinoma (HCC) remains unclear. Herein, we perform a meta-analysis to assess diagnostic value of lncRNAs for HCC. METHODS: The online PubMed, Cochrane, Web of Science, and Embase database were searched for eligible studies published until October 5, 2016. Study quality was evaluated with the Quality Assessment for Studies of Diagnostic Accuracy (QUADAS). All statistical analyses were conducted with Stata 12.0 and Meta-Disc 1.4. RESULTS: We included 19 studies from 10 articles with 1454 patients with HCC and 1300 controls. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and AUC for lncRNAs in the diagnosis of HCC were 0.83 (95% confidence interval [CI]: 0.76-0.88), 0.80 (95% CI: 0.73-0.86), 4.2 (95% CI: 3.00-5.80), 0.21 (95% CI: 0.15-0.31), 20 (95% CI: 11-34), and 0.88 (95% CI: 0.85-0.91), respectively. Additionally, the diagnostic value of lncRNAs varied based on sex ratio of cases and characteristics of methods (specimen type and reference gen). CONCLUSION: This meta-analysis suggests lncRNAs show a moderate diagnostic accuracy for HCC. However, prospective studies are required to confirm its diagnostic value.

Neuropathological injury in the mammalian adult central nervous system (CNS) may cause axon disruption, neuronal death and lasting neurological deficits. Failure of axon regeneration is one of the major challenges for CNS functional recovery. Recently, the cAMP/PKA signaling pathway has been proven to be a critical regulator for neuronal regeneration, neuroplasticity, learning and memory. Also, previous studies have shown the effects of Chinese medicines on the prevention and treatment of CNS dysfunction mediated in part by cAMP/PKA signaling. In this review, the authors discuss current knowledge of the role of cAMP/PKA signaling pathway in neuronal regeneration and provide an overview of the Chinese medicines that may enable CNS functional recovery via this signaling pathway.

BACKGROUND: A phase II study was performed to investigate the safety and efficacy of weekly doses of combined paclitaxel and 5-fluorouracil (5-FU) with concurrent radiation therapy, followed by 2 cycles of consolidation chemotherapy to treat patients with advanced oesophageal carcinoma. METHODS: The eligibility criteria included local, advanced, newly diagnosed and postoperative local regional lymph node metastasis; an Eastern Cooperative Oncology Group (ECOG) score of ≤ 2; and adequate organ function. Patients received chemoradiotherapy consisting of radiotherapy (50.4 Gy/28 Fx or 61.2 Gy/34 Fx) and concurrent paclitaxel (50 mg/m2) and 5-FU (300 mg/m2) for 96 h on days 1, 8, 15, 22, and 29. The two-cycle consolidation chemotherapy protocol included paclitaxel (175 mg/m2) plus continuously infused 5-FU (1800 mg/m2) for 72 h administered on days 57 and 85, after concurrent chemoradiotherapy. RESULTS: Between February 2012 and August 2013, 53 patients with oesophageal carcinoma were enrolled in the study. Among these patients, 33 (62.2%) were newly diagnosed and 20 (37.7%) had postoperative local regional lymph node metastasis. The median overall survival (OS) time was 17.9 months (95% CIs = 11.9-23.9), and the median progression-free survival (PFS) time was 12.4 months (95% CIs = 8.6-16.1). Approximately 84.9% (45/53) and 50.9% (27/53) of the patients completed ≥ 5 cycles and all 7 cycles of chemotherapy, respectively. Approximately 86.7% (46/53) of patients completed radiation therapy. The 1-, 2-, and 3-year OS rates were 66.0%, 37.7%, and 35.8%, respectively. The 1-, 2-, and 3-year local control rates were 76.9%, 66.4%, and 66.4%, respectively. Seventeen patients (32%) experienced grade 3 or higher toxicity. Grade 3 to 5 toxicity during chemoradiotherapy included neutropaenia (7.5%), thrombocytopaenia (1.8%), fatigue (7.5%), anaemia (1.8%), dermatitis radiation (1.8%), pneumonitis (5.6%), oesophagitis (9.4%) and vomiting (3.7%). CONCLUSIONS: The combination of weekly doses of paclitaxel and 5-FU was well tolerated and produced comparable results among patients with locally advanced oesophageal cancer. A randomised phase III trial (NCT01591135) comparing paclitaxel plus 5-FU with cisplatin plus 5-FU is on-going at our hospital.

AIM: To evaluate the long-term effectiveness and late toxicities of paclitaxel (PTX) plus cisplatin (DDP) with concurrent radiotherapy for locally advanced esophageal squamous cancer. METHODS: Between 2008 and 2011, 76 patients were enrolled in a phase II study on the treatment of loco-regionally advanced esophageal cancer with radiotherapy (68.4 Gy/44 fractions or 61.2 Gy/34 fractions) combined with 4-cycle chemotherapy consisting of DDP (25 mg/m2 per day for 3 d) and PTX (175 mg/m2 for 3 h). The primary endpoints were overall survival and progression-free survival, and the secondary endpoints were toxicity and the treatment failure pattern. RESULTS: A total of 76 patients were enrolled in this study, of whom 63.2% finished the whole regimen. The 5-year survival rates for the per-protocol population and intent-to-treat population were 25.4% and 26.4%, respectively, and the median survival rates were 23.7 mo and 28.5 mo, respectively. Grade 3 or 4 late toxicity was observed in only one patient (heart failure). In log-rank analysis, the pretreatment stage (stage II + III: 36.1 mo vs stage IV: 14.9 mo) and the completed cycle (1-3 cycles: 16.1 mo vs 4 cycles: 35.5 mo) were significant prognostic factors (P = 0.037 < 0.05 and P = 0.013 < 0.05). CONCLUSION: Radiotherapy combined with chemotherapy consisting of PTX and DDP is a safe and effective definitive treatment for loco-regionally advanced esophageal squamous cancer.

An esophageal squamous cell carcinoma measuring 18.3 cm in length and 5 cm in diameter was found in the mediastinum of a 53-year man. The patient underwent a modified 3-stage esophagectomy and an esophagogastrostomy at the cervical level (Wu's method). The operation was performed smoothly and the patient recovered uneventfully after the operation. The patient was followed up for 6 months after discharge and reported no difficulties in eating with improved quality of life. This case represents the world's longest esophageal cancer that had been surgically removed. Local advanced esophageal cancer should be removed immediately to prevent potential occurrence of esophageal obstruction, tracheoesophageal fistula or aorto-esophageal fistula.
