Water-free solvent soluble, low-temperature processed metal oxides are important for preparing efficient and stable electronic devices, as well as the convenience in simplifying the device production process. Here we reported a facile approach with the features of low-temperature and solution-based process for the formation of a MoOx (s-MoOx) film as interface layer in polymer solar cells (PSCs). The absorbability, elementary composition, electronic property and surface microstructure of the s-MoOx are investigated in detail by ultravioletevisible spectrophotometer (UVevis), X-ray photoelectron spectrometry (XPS), ultraviolet photo-electron spectrometer (UPS) and atomic force microscopy (AFM). These investigations confirmed that such MoOx xerogel has high solubility in the organic alcohol solvents, such as ethanol and methanol. Meanwhile, this s-MoOx can be applied as the interfacial layer in organic solar cells via a low-temperature treatment (about 100 C) due to its proper physical properties, and a power conversion efficiency (PCE) over 3% was achieved. In addition, the devices with s-MoOx shows excellent air-stability, and the PCE efficiency can maintain about 84% of its initial value after 100 h exposure in air, which is dramatically enhanced comparing with the common devices with PEDOT:PSS layer.

Since there is no consensus about the most reliable assays to detect invasive aspergillosis from samples obtained by minimally invasive or noninvasive methods, we compared the efficacy of an enzyme-linked immunosorbent assay (ELISA) for galactomannan (GM) detection and quantitative real-time PCR assay (qRT-PCR) for the diagnosis of invasive pulmonary aspergillosis. Neutropenic, male Sprague-Dawley rats (specific pathogen free; 8 weeks old; weight, 200 ± 20 g) were immunosuppressed with cyclophosphamide and infected with Aspergillus fumigatus intratracheally. Tissue and whole blood samples were harvested on days 1, 3, 5, and 7 post-infection and examined with GM ELISA and qRT-PCR. The A. fumigatus DNA detection sequence was detected in the following number of samples from 12 immunosuppressed, infected rats examined on the scheduled days: day 1 (0/12), day 3 (0/12), day 5 (6/12), and day 7 (8/12) post-infection. The sensitivity and specificity of the qRT-PCR assay was 29.2% and 100%, respectively. Receiver operating characteristic curve (ROC) analysis indicated a Ct (cycle threshold) cut-off value of 15.35, and the area under the curve (AUC) was 0.627. The GM assay detected antigen in sera obtained on day 1 (5/12), day 3 (9/12), day 5 (12/12), and day 7 (12/12) post-infection, and thus had a sensitivity of 79.2% and a specificity of 100%. The ROC of the GM assay indicated that the optimal Ct cut-off value was 1.40 (AUC, 0.919). The GM assay was more sensitive than the qRT-PCR assay in diagnosing invasive pulmonary aspergillosis in rats.

Biological preservatives containing live microorganisms are environmentally friendly and non-toxic substances used to preserve the quality of fresh fruits. This study investigated whether a composite biological preservative containing live Lactobacillus plantarum (designated as DN003) could preserve the quality of postharvest litchi fruits at high temperature and in humid environment. Postharvest litchi fruits were briefly soaked in DN003, then dried and stored at 29–33oC with 95–98% relative humidity; prochloraz treatment was included as positive control and non-treatment as negative control. In comparison with negative control group, litchi fruits in both DN003-treated and positive control groups better retained their appearance with lower polyphenol oxidase and peroxidase activities and showed higher concentrations of vitamin C, titratable acids, and total sugar content. These data demonstrated that the new composite biological preservative containing L. plantarum is promising to be used in the preservation of postharvest litchi fruit, particularly in hightemperature and humid environment.

A network meta-analysis of the short-term efficacy of five chemotherapy regimens based on cisplatin and fluorouracil for esophagogastric junctional adenocarcinoma

Cong Wang,Dong-Jian Song,Zhi-Li Xu,Shu-Ping Xie,Jun-Hong Hu 생화학분자생물학회 2017 Experimental and molecular medicine Vol.49 No.-

The primary purpose of this study was to explore the short-term efficacy of different cisplatin and fluorouracil-based chemotherapy regimens in the treatment of patients with esophagogastric junctional adenocarcinoma (EGJA) using a network meta-analysis (NMA). Randomized controlled trials (RCTs) related to chemotherapy regimens based on cisplatin and fluorouracil for EGJA were included from the PubMed, EMBASE and Cochrane Library electronic databases (from inception to June 2016). Direct and indirect evidence were combined to calculate the pooled odds ratio (OR) and its 95% confidence interval (95% CI) as well as to draw the surface under the cumulative ranking (SUCRA) curves. This NMA finally enrolled ten eligible RCTs with the following five regimens: cisplatin plus fluorouracil (cisplatin+fluorouracil), cisplatin+fluorouracil-based chemotherapy (cisplatin+fluorouracil+docetaxel/epirubicin/irinotecan), fluorouracil-based chemotherapy (fluorouracil+docetaxel/doxorubicin/ methotrexate/irinotecan), cisplatin-based chemotherapy (cisplatin+docetaxel/epirubicin/irinotecan/capecitabine/s-1) and other drug-based chemotherapy (docetaxel/irinotecan/capecitabine). These results revealed that compared with a cisplatin+ fluorouracil-based chemotherapy regimen, the fluorouracil-based chemotherapy regimen had a lower overall response rate (ORR) and partial response (PR) for EGJA patients (ORR: OR=0.43, 95% CI=0.22–0.86; PR: OR=0.46, 95% CI=0.23–0.91). Cluster analyses suggested that the cisplatin+fluorouracil-based chemotherapy regimen had the best short-term efficacy for EGJA in terms of the complete response (CR), PR, ORR, stable disease (SD) and progression disease (PD). Our results indicated that cisplatin+fluorouracil-based chemotherapy regimens may have the best short-term efficacy in the treatment of EGJA

Evolution of ALPPS: The Simpler, Safer and Effective One---TELPP

( Shu You Peng ),( Xu An Wang ),( Cong Yun Huang ),( You Yong Zhang ),( Jiang Tao Li ),( De Fei Hong ),( Xiu Jun Cai ),( Yi Fang Wang ),( Xiao Liang ),( Jian Wei Wang ) 대한간학회 2017 춘·추계 학술대회 (KASL) Vol.2017 No.1

Aims: The characteristic of associating liver partition and portal vein ligation for staged hepatectomy(ALPPS) carries high mortality and morbidity. There is room for improvement. We suggest Terminal Branches Portal Vein Embolization (TBPVE) as a way to compart the liver. As a result, only a single surgical operation is required.This method is termed Terminal branches portal vein Embolization Liver Partition Planned hepatectomy (TELPP). Methods: Patients with unresectable primary or metastatic liver tumor were performed with TELPP. The procedure of TELPP was that in addition to PVE, embolization agent was infused to the terminal branches of portal vein of S5,S8 or S4. CT scan was taken one or two weeks later, and standard liver volume(SLV), FLR and FLR/SLV are calculated. Two weeks later when the FLR and liver function is appropriate, open or laparoscopic hepatectomy is performed. Results: The study included 11patients including hepatocellular carcinoma: n =8, intrahepatic cholangiocarcinoma: n = 1, hilarcholangiocarcinoma: n =1, colorectal liver metastasis: n =1. After a waiting period of 14 days, the volume of theFLR had increased from 382mlto 578ml, representing a median volume increase of 51% (range =32.5%-86.7%). Of the 11patients with hepatectomy, right hemihepatectomy (n=2), extended right hemihepatectomy (n=5), right trisecmentectomy(2), extended left hemihepatectomy (n=1) and left trisecmentectomy(1). No patient died, and no serve perioperative morbidity occurred. Conclusions: ALPPS and all modifications need two-stage operations with a high morbidity and mortality rate. It seems that TELPP is very promising. It has the merit of ALPPS as extraordinarily rapid increasement of FLRvolume, yet the morbidity and mortality is much lower, owing to the fact that unlike ALPPS, there is no two liver raw surfaces left behind in the abdominal cavity to produce bile leak, as only single surgical operation is required

The Relationship Between Preoperative Cervical Sagittal Balance and Clinical Outcome of Patients With Hirayama Disease Treated With Anterior Cervical Discectomy and Fusion

Xiao Lu,Guang-Yu Xu,Cong Nie,Yu Xuan Zhang,Jian Song,Jianyuan Jiang 대한척추신경외과학회 2021 Neurospine Vol.18 No.3

Objective: Anterior cervical discectomy and fusion (ACDF) is a common surgical method used to treat patients with Hirayama disease. And sagittal balance indexes have been revealed to be predictors of clinical outcomes in patients with cervical diseases, but their relationships with ACDF-treated Hirayama disease outcomes remain unknown. The purpose of this study is to evaluate the relationship of preoperative cervical sagittal balance indexes and clinical outcomes in ACDF-treated Hirayama disease patients. Methods: Eighty patients with Hirayama disease treated by ACDF were reviewed retrospectively. Six cervical sagittal balance parameters were collected including Cobb angle, T1 slope, C1–7 sagittal vertical axis (SVA), C2–7 SVA, center of gravity of the head (CGH)-C7 SVA, range of motion. The recovery outcomes of the patients were divided into 2 groups by Odom score and the differences in recovery between the 2 groups were confirmed by electromyography. The correlation between imaging parameters and postoperative outcome was evaluated with logistic regression. The receiver operating characteristic (ROC) curve and area under the ROC curve (AUC) were used to evaluate the significant result of logistic regression and the optimal diagnostic value. Results: Only 2 parameters, Cobb angle and CGH-C7 SVA, showed statistical correlation with the postoperative outcome assessment by logistic regression. AUC of Cobb angle and CGH-C7 SVA were 0.559 and 0.702 respectively. The optimal predictive threshold was 1.50° and 5.40 mm, respectively. Conclusion: A larger Cobb angle and smaller CGH-C7 SVA seemed to correlate with a better postoperative outcome. These 2 factors could be used to predict the outcome of surgical treatment of Hirayama disease preoperatively.

Bao, Ci-Hang,Liu, Kun,Wang, Xin-Tong,Ma, Wei,Wang, Jian-Bo,Wang, Cong,Jia, Yi-Bin,Wang, Na-Na,Tan, Bing-Xu,Song, Qing-Xu,Cheng, Yu-Feng Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.5

Hepatoma-derived growth factor (HDGF) is a novel jack-of-all-trades in cancer. Here we quantify the prognostic impact of this biomarker and assess how consistent is its expression in solid tumors. A comprehensive search strategy was used to search relevant literature updated on October 3, 2014 in PubMed, EMBASE and WEB of Science. Correlations between HDGF expression and clinicopathological features or cancer prognosis was analyzed. All pooled HRs or ORs were derived from random-effects models. Twenty-six studies, primarily in Eastern Asia, covering 2,803 patients were included in the analysis, all of them published during the past decade. We found that HDGF overexpression was significantly associated with overall survival (OS) ($HR_{OS}=2.35$, 95%CI=2.04-2.71, p<0.001) and disease free survival (DFS) ($HR_{DFS}=2.25$, 95%CI =1.81-2.79, p<0.001) in solid tumors, especially in non-small cell lung cancer, hepatocellular carcinoma and cholangiocarcinoma (CCA). Moreover, multivariate survival analysis showed that HDGF overexpression was an independent predictor of poor prognosis ($HR_{OS}=2.41$, 95%CI: 2.02-2.81, p<0.001; $HR_{DFS}=2.39$, 95%CI: 1.77-3.24, p<0.001). In addition, HDGF overexpression was significantly associated with tumor category (T3-4 versus T1-2, OR=2.12, 95%CI: 1.17-3.83, p=0.013) and lymph node status (N+ versus N-, OR=2.37, 95%CI: 1.31-4.29, p=0.03) in CCA. This study provides a comprehensive examination of the literature available on the association of HDGF overexpression with OS, DFS and some clinicopathological features in solid tumors. Meta-analysis results provide evidence that HDGF may be a new indicator of poor cancer prognosis. Considering the limitations of the eligible studies, other large-scale prospective trials must be conducted to clarify the prognostic value of HDGF in predicting cancer survival.
