Abstract
Host-directed therapy (HDT) is a new adjuvant strategy that interfere with host cell factors that are required by a pathogen for replication or persistence. In this study, we assessed the effect of dehydrozaluzanin C-derivative (DHZD), a modified compound from dehydrozaluzanin C (DHZC), as a potential HDT agent for severe infection. LPS-induced septic mouse model and Carbapenem resistant Klebsiella pneumoniae (CRKP) infection mouse model was used for testing in vivo. RAW264.7 cells, mouse primary macrophages, and DCs were used for in vitro experiments. Dexamethasone (DXM) was used as a positive control agent. DHZD ameliorated tissue damage (lung, kidney, and liver) and excessive inflammatory response induced by LPS or CRKP infection in mice. Also, DHZD improved the hypothermic symptoms of acute peritonitis induced by CRKP, inhibited heat-killed CRKP (HK-CRKP)-induced inflammatory response in macrophages, and upregulated the proportions of phagocytic cell types in lungs. In vitro data suggested that DHZD decreases LPS-stimulated expression of IL-6, TNF-α and MCP-1 via PI3K/Akt/p70S6K signaling pathway in macrophages. Interestingly, the combined treatment group of DXM and DHZD had a higher survival rate and lower level of IL-6 than those of the DXM-treated group; the combination of DHZD and DXM played a synergistic role in decreasing IL-6 secretion in sera. Moreover, the phagocytic receptor CD36 was increased by DHZD in macrophages, which was accompanied by increased bacterial phagocytosis in a clathrin- and actin-dependent manner. This data suggests that DHZD may be a potential drug candidate for treating bacterial infections.

Abstract
OBJECTIVE To explore the effect of miR-873-5p on proliferation, apoptosis, migration, and invasion of tongue squamous cell carcinoma (TSCC) by targeting SEC11A. METHODS Tongue squamous cell carcinoma tissues were collected and performed by qRT-PCR and Western blotting to determine the expression of miR-873-5p and SPC18. SCC9 and CAL-27 cells were transfected and divided into Mock, mimic NC, miR-873-5p mimic, SEC11A, and miR-873-5p mimic + SEC11A groups. Then, a series of experiments including cell count kit 8 (CCK-8), wound healing, Transwell, and flow cytometry were conducted. Besides, Western blotting was used to detect the expression of SPC18 and EGFR pathway-related proteins. RESULTS MiR-873-5p was downregulated while SPC18 was upregulated in TSCC, and miR-873-5p was negatively correlated with SPC18. Dual luciferase reporter gene assay confirmed SEC11A to be a target of miR-873-5p. Cell proliferation, migration, and invasion of SCC9 and CAL-27 cells in miR-873-5p mimic group were decreased with increased cell apoptosis, presenting with downregulations of SPC18 and EGFR pathway-related proteins, while cells in SEC11A group manifested totally different changes. Moreover, the inhibitory effect of miR-873-5p mimic on TSCC cell growth was abolished by SEC11A overexpression. CONCLUSION Overexpression of miR-873-5p may suppress cell proliferation, migration, and invasion, but facilitate apoptosis in TSCC via targeting SEC11A.

Abstract
Objective: The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods: We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results: The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage Ⅰ, Ⅱ, ⅢA, ⅢB and Ⅵ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all). Conclusions: The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.

Abstract
The present study aimed to investigate whether the long non-coding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) can promote the migration and invasion of human oral squamous cell carcinoma (OSCC) cells via the regulation of epithelial-mesenchymal transition (EMT). CAL-27 and SCC-15 cells were classified into a control group, a small interfering negative control (si-NC) group (cells transfected with control siRNA) and an si-CRNDE group (cells transfected with CRNDE siRNA). The expression of CRNDE in OSCC tissues and cell lines was detected by in situ hybridization (ISH) and reverse transcription-quantitative polymerase chain reaction. An MTT assay was used to detect cell proliferation, flow cytometry was performed to determine cell apoptosis, wound-healing and Transwell assays were conducted to evaluate cell metastasis, and immunofluorescence staining and western blotting were performed to measure the expression of proteins associated with EMT. Tumor-bearing mouse models were established, and the tumor volumes were recorded. An immunohistochemical assay was performed to determine the expression of EMT-related proteins. CRNDE expression was increased in OSCC tissues and cell lines compared with that in normal tissues and cell lines. Compared with the control group, the si-CRNDE group displayed a reduction in the expression of CRNDE, in the proliferation, migration and invasion of cells, in the protein expression of N-cadherin, vimentin and Snail, and in the expression of proteins in the Wnt/β-catenin pathway. However, an increase was displayed in the apoptosis of cells and the expression of E-cadherin. Compared with the control group of tumor-bearing nude mice, the sh-CRNDE group demonstrated slowed tumor growth, reduced tumor weight and elevated E-cadherin, as well as reduced expression of N-cadherin, vimentin and Snail. In conclusion, silencing CRNDE may inhibit EMT, thus decreasing the migration and invasion of human OSCC cells by repressing the activation of the Wnt/β-catenin signaling pathway, thereby restricting cell growth and promoting cell apoptosis.

Abstract
Objective: To analyze risk factors of anastomotic leakage after McKeown'sesophagectomy. Methods: The clinical data of 635 esophageal cancer patients, who underwent McKeown's esophagectomy at Cancer Hospital of Chinese Academy of Medical Sciences from January 2012 to December 2015, were retrospectively analyzed. The risk factors of cervical anastomotic leakage were identified through analysis of medical history, surgical procedure, tumor characteristics and vascular calcification. Results: Among all the 635 patients, anastomotic leakage occurred in 111 (17.5%)patients. Univariate analysis showed that the American Society of Anesthesiologists (ASA) risk class, prior thoracic surgery, upper digestive tract ulcer, COPD, hypertension, peripheral vascular disease, renal insufficiency, FEV1% predicted, DLCO% predicted, duration of surgery and calcification of descending aorta, celiac trunk and left postceliac arteries were associated with a statistically significant increase in risk of cervical anastomotic leakage (P<0.05 for all). Logistic regression analysis showed that ASA risk class, peripheral vascular disease, renal insufficiency and calcification of descending aorta and celiac trunk were independent risk factors of cervical anastomotic leakage after McKeown's esophagectomy (P<0.05 for all). Conclusions: ASA risk class, peripheral vascular disease, renal insufficiency, calcification of descending aorta and celiac trunk are independent risk factors of cervical esophageal anastomotic leakage after McKeown's esophagectomy.

Abstract
OBJECTIVE To explore the clinical characteristics of patients with bilateral synchronous multiple primary non-small cell lung cancer (NSCLC) and identify the prognostic indicators associated with survival. METHODS From January 2010 to December 2014, clinicopathological data of 96 patients with bilateral synchronous multiple primary NSCLC, who met the modified Martini-Melamed criteria and underwent radical surgical resection, were retrospectively reviewed. Survival was estimated using the Kaplan-Meier method, and the clinical parameters associated with survival were analyzed using a log-rank test. Cox proportional hazards regression models were used to identify the risk factors for this cancer. RESULTS Of the 96 patients, two patients who died of severe postoperative complications were excluded, and 94 patients were analyzed. Of the 94 cases, a two-stage operation was performed in 93 patients, while a single-stage bilateral surgery was performed in only one patient using video-assisted thoracic surgery (VATS). 79 patients had 2 tumors and the other 15 patients had 3 or more tumors. There were 82 patients with synchronous tumors located in different lobes and 12 patients had at least two tumors located in the same lobe. Seventy-six patients were found to have multiple lung adenocarcinoma and 12 patients had multiple squamous cell carcinoma (SCCs). Five patients had adenocarcinoma and SCC, and one patient had adenocarcinoma and adenosquamous carcinoma simultaneously. Univariate analysis showed that the large maximum tumor diameter, highest pT stage and lymph node involvement were associated with an unfavorable DFS (P<0.01 for all), while female gender, small maximum tumor diameter, early highest pT stage and pN0 were associated with a better overall survival (OS). Multivariate analysis showed that highest pT stage and lymph node metastasis were independent prognostic factors for DFS and OS. Patients with a lower highest pT stage and negative lymph node metastasis had longer DFS and OS (P<0.05 for both). CONCLUSIONS The diagnosis for patients with bilateral synchronous multiple primary NSCLCs should be made very carefully. Two stage surgical treatment is safe, reasonable and effective for patients with bilateral synchronous multiple primary NSCLCs in a relatively early stage. The highest pT stage and pN status are important predictors for long-term survival. Adequate pulmonary tissue resection with complete resection of multiple nodules and systematic lymphadenectomy are suggested.

Abstract
The effects of hypothermia on caspase-3 activation were investigated in the newborn rat brain after hypoxia-ischemia (HI). Intense caspase-3 activation was observed in the control brains after HI, but this activation was significantly reduced by postischemic hypothermia. These findings suggest that the inhibition of caspase-3 activation may be an interventional point underlying the neuroprotective effect of hypothermia in neonates.

Abstract
Two hybridomas which secrete monoclonal antibody (McAb) against polymerized human serum albumin (PHSA) were obtained by the fusion of SP2/0 myeloma cell with immune murine spleen cells. One of the McAb was identified as mouse IgG1, the other was IgM. The titers of these purified McAb was 1:16 364 with passive hemagglutination assay (PHA). After labelling with 125I by chloramine-T method, a solid phase radioimmune assay for detecting the PHSA has yielded in 21 positive results, out of 126 HBsAg positive sera, but 53 HBsAg negative sera were all negative. At present we have not seen any report of PHSA present in circulation. PHSA may be as a bridge bind receptor between HBV and hepatocytes and then initiate infection. The appearance of PHSA in HBsAg positive sera could be the result of the damage of the liver during virus infection. More work should be done for this explanation.
