Abstract
INTRODUCTION Surgical site infection is one of the most common complications for patients after sacrectomy, which often accompanied by poor wound healing, sinus formation and serious metabolic disturbance. HYPOTHESIS We tried to avoid the surgical site infection caused by feces during early period after surgery through early fasting and total parenteral nutrition (TPN) support, then compared the clinical results of these patients with other patients that received enteral nutrition (EN) early after sacrectomy. METHODS Forty-eight patients after sacrectomy (the level of sacrectomy above S2) were randomly divided into two groups: TPN group and EN group. The patients of two groups received different nutrition support from the first day to the seventh day after surgery, then the factors such as nutritional and metabolic status after surgery, incidence of complications as well as the time of incision healing and hospitalization were observed. RESULTS The p-value of total serum protein, albumin, serum alanine aminotransferase, total bilirubin at seventh day after sacrectomy between TPN group and EN group is <0.0005. The p-value of hemoglobin at seventh day after sacrectomy between TPN group and EN group is 0.001. The p-value of total serum protein at fourteenth day after sacrectomy between TPN group and EN group is 0.003. The p-value of albumin and total bilirubin at fourteenth day after sacrectomy between TPN group and EN group is 0.001. The p-value of hemoglobin, serum alanine aminotransferase at fourteenth day after sacrectomy between TPN group and EN group is <0.0005. The incidence of gastrointestinal complication and delay of apparition of feces in EN group were lower than that in TPN group (p=0.041, p<0.0005). The incidence of surgical site infection, the time of incision healing and hospitalization in TPN group were lower than that in EN group (p=0.048, p=0.008, p<0.0005). CONCLUSIONS The method of fasting and supported by TPN during the early period after sacrectomy contribute to the incision healing, meanwhile, it shortens the hospitalization time and abates the incidence of complications in patients after sacrectomy. TYPE OF STUDY It is a comparative randomized study. LEVEL OF PROOF High-powered prospective randomized trial.

Abstract
The surgical approach to the resection of oral tongue cancers can involve transoral resection (TOR) or a temporary mandibulotomy access (TMA). There are no relevant guidelines, and the oncological safety of TOR needs consideration. The objective of this study was to investigate TMA and TOR in pT2 oral tongue cancer surgery with regard to cancer outcomes. Demographic, surgical, and histology data from primary pT2 tongue cancers were recorded and evaluated through multivariate Cox regression for local recurrence (LR), disease-free survival (DFS), and overall survival (OS). A total of 166 patients with pT2 primary oral tongue cancer fulfilled the inclusion criteria; TOR was used in 95 patients and TMA in 71 patients. The minimum follow-up was 29 months. Group comparisons showed a significantly higher frequency of perineural spread (P=0.013) in the TMA group; a higher frequency of involved margins on initial resection was seen in TOR patients (P=0.010). Adjuvant postoperative radiotherapy was preferred in the TMA group, in line with the high pN positive status. Multivariate Cox regression showed significantly higher LR and lower DFS in the TOR group despite stratification of the major prognostic factors. The 5-year survival rate was reduced to 82.2% in the TOR group, while it remained constant at 93.0% in the TMA group. TMA provided superior local control and DFS compared to TOR in pT2 tongue cancers.

Abstract
Objective: To investigate the spectrum of gene mutations in adult patients with B-acute lymphoblastic leukemia (B-ALL), and to analyze the influences of different gene mutations on prognosis. Methods: DNA samples from 113 adult B-ALL patients who administered from June 2009 to September 2015 were collected. Target-specific next generation sequencing (NGS) approach was used to analyze the mutations of 112 genes (focused on the specific mutational hotspots) and all putative mutations were compared against multiple databases to calculate the frequency spectrum. The impact of gene mutation on the patients' overall survival (OS) and recurrence free survival (RFS) was analyzed by the putative mutations through Kaplan-Meier, and Cox regression methods. Results: Of the 113 patients, 103 (92.0%) harbored at least one mutation and 29 (25.6%) harbored more than 3 genes mutation. The five most frequently mutated genes in B-ALL are SF1, FAT1, MPL, PTPN11 and NRAS. Gene mutations are different between Ph+ B-ALL and Ph- B-ALL patients. Ph- B-ALL patients with JAK-STAT signal pathway related gene mutation, such as JAK1/JAK2 mutation showed a poor prognosis compared to the patients without mutation (OS: P=0.011, 0.001; RFS: P=0.014,<0.001). Patients with PTPN11 mutation showed better survival than those without mutation, but the difference was not statistically significant (P value > 0.05). Besides, in Ph+ B-ALL patients whose epigenetic modifications related signaling pathway genes were affected, they had a worse prognosis (OS: P=0.038; RFS: P=0.047). Conclusion: Gene mutations are common in adult ALL patients, a variety of signaling pathways are involved. The frequency and spectrum are varied in different types of B-ALL. JAK family gene mutation usually indicates poor prognosis. The co-occurrence of somatic mutations in adult B-ALL patients indicate the genetic complex and instability of adult B-ALL patients.

Abstract
Pulmonary arterial hypertension (PAH) is a rare and severe complication of primary Sjögren's syndrome (pSS). Cohort studies indicate that the underlying diseases of PAH associated with connective tissue disease (CTD-PAH) in Asian countries are different from that in the United States and in Europe. This study investigated the clinical characteristics, survival, and prognostic factors of pSS-PAH in Chinese patients. We enrolled 29 patients with pSS-PAH who visited our referral center during August 2007 and May 2015. PAH was confirmed by right heart catheterization (RHC). Baseline demographic data, clinical manifestations, laboratory tests, autoantibody results, hemodynamics data, and treatment regimens were analyzed. All patients were followed up at the Department of Rheumatology, Peking Union Medical College Hospital (PUMCH) every three to six months. All patients were female. Mean age of pSS onset was 34.4 ± 11.1 years. Mean age of PAH diagnosed by RHC was 40.6 ± 9.0 years. There was no significant difference in age, disease duration, and hemodynamic findings between the survivors and the non-survivors in this cohort. The overall one-, three-, and five-year survival rates were 80.2%, 74.8%, and 67.4%, respectively. Prognostic factors of mortality were time between pSS onset and PAH onset (HR 1.102, 95% CI 1.017-1.185, p = 0.018) and cardiac index < 2 l/min/m2 (HR 5.497, 95% CI 1.063-28.434, p = 0.042). In contrast, the use of immunosuppressants (HR 0.110, 95% CI 0.024-0.495, p = 0.004) was related to better survival. This study demonstrates that the predictors of mortality in patients with pSS-PAH include delayed onset of PAH in pSS and worse cardiac function. Immunosuppressants can improve the prognosis of pSS-PAH.

Abstract
Objective: To investigate the safety and efficacy of the Weitan Waifu patch on the postsurgical gastroparesis syndrome (PGS) of gastrointestinal cancer. Methods: The multi-center, double-blind, randomized controlled trial was conducted with superiority design. Patients with PGS of gastrointestinal cancer diagnosed in 4 AAA hospitals and the abdominal symptom manifested as cold syndrome by Chinese local syndrome differentiation were recruited. These patients were randomly divided into two groups according to 1∶1 proportion. Placebo or Weitan Waifu patch was applied in control group or intervention group, respectively, based on the basic treatments, including nutrition support, gastrointestinal decompression, promoting gastric dynamics medicine.Two acupuncture points (Zhongwan and Shenque) were stuck with placebo in control group or patch in treatment group. The intervention course was 14 days or reached the effective standard. Results: From July 15, 2013 to Jun 3, 2015, 128 participants were recruited and 120 eligible cases were included in the full analysis set (FAS), and 60 cases in each group. 88 cases were included in the per-protocol set (PPS), including 45 cases in the treatment group and 43 cases in the control group. In the FAS, the clinical effective rate in the treatment group was 68.3%, significantly superior than 41.7% of the control group (P=0.003). The medium time of effective therapy in the treatment group was 8 days, significantly shorter than 10 days in the control group (P=0.017). In the FAS, 3 adverse events occurred in the treatment group, including mild to moderate decrustation, pruritus and nausea. The incidence rate of adverse events was 5.0% (3/60) and these symptoms were spontaneously remitted after drug withdrawal. No severe adverse events were observed in the control group. There was no significant difference between these two groups (P=0.244). Conclusion: Weitan Waifu patch is a safely and effectively therapeutic method for patients with PGS (cold syndrome) of gastroenterological cancer. Trial registration: International Standard Randomized Controlled Trial Number Register, ISRCTN18291857.

Abstract
PURPOSE Current clinical brachytherapy dose calculations are typically based on the Association of American Physicists in Medicine Task Group report 43 (TG-43) guidelines, which approximate patient geometry as an infinitely large water phantom. This ignores patient and applicator geometries and heterogeneities, causing dosimetric errors. Although Monte Carlo (MC) dose calculation is commonly recognized as the most accurate method, its associated long computational time is a major bottleneck for routine clinical applications. This article presents our recent developments of a fast MC dose calculation package for high-dose-rate (HDR) brachytherapy, gBMC, built on a graphics processing unit (GPU) platform. METHODS AND MATERIALS gBMC-simulated photon transport in voxelized geometry with physics in (192)Ir HDR brachytherapy energy range considered. A phase-space file was used as a source model. GPU-based parallel computation was used to simultaneously transport multiple photons, one on a GPU thread. We validated gBMC by comparing the dose calculation results in water with that computed TG-43. We also studied heterogeneous phantom cases and a patient case and compared gBMC results with Acuros BV results. RESULTS Radial dose function in water calculated by gBMC showed <0.6% relative difference from that of the TG-43 data. Difference in anisotropy function was <1%. In two heterogeneous slab phantoms and one shielded cylinder applicator case, average dose discrepancy between gBMC and Acuros BV was <0.87%. For a tandem and ovoid patient case, good agreement between gBMC and Acruos BV results was observed in both isodose lines and dose-volume histograms. In terms of the efficiency, it took ∼47.5 seconds for gBMC to reach 0.15% statistical uncertainty within the 5% isodose line for the patient case. CONCLUSIONS The accuracy and efficiency of a new GPU-based MC dose calculation package, gBMC, for HDR brachytherapy make it attractive for clinical applications.

Abstract
Neuropilin 2 (Nrp2) plays an important role in regulating lymphangiogenesis. Nrp2 expression in early tongue cancer was investigated to predict lymph node metastasis and the long-term prognosis. The relationships between clinicopathological variables of cT1-T2N0 tongue squamous cell carcinoma (SCC) and overexpression of Nrp2, vascular endothelial growth factor C (VEGFC), vascular endothelial growth factor receptor 3 (VEGFR3), and semaphorin 3F (Sema3F) were analyzed. Expression levels were compared using oral SCC cell lines. The Nrp2 gene was silenced to determine the impact of Nrp2. Cytoplasmic Nrp2 overexpression predicted regional metastasis with sensitivity and specificity of 90.3% and 42.1%, respectively. Cytoplasmic Nrp2 overexpression (P<0.001) and VEGFC overexpression (P=0.006) were significantly related to regional metastasis (Student t-test). However, only cytoplasmic Nrp2 overexpression was an independent prognostic factor for both disease-free survival (DFS; P=0.008) and overall survival (OS; P=0.016) (Cox regression); the risk of recurrence was 12-times higher (P=0.015) and risk of mortality was 8-times higher (P=0.016). Co-localization of Nrp2 and VEGFC was greater within the cytoplasm of aggressive cell lines (HN12 and RCa-T). Nrp2 plays a role in tumourigenesis; VEGFC supplementation cannot rescue the biological function of Nrp2 in Nrp2-depleted cell lines. Cytoplasmic Nrp2 overexpression is associated with decreased OS and DFS. Cytoplasmic Nrp2 overexpression may be a reliable diagnostic and prognostic marker for early tongue SCC.

Abstract
Background Hyperthermia is considered an efficient complement in the treatment of head and neck squamous cell carcinoma (HNSCC). Hyperthermia induces cell apoptosis in a temperature- and time-dependent manner. However, the molecular mechanism of hyperthermia remains unclear. The aim of this study was to investigate the mechanism of apoptosis induced by ultrasound hyperthermia in HNSCC cell lines HN-30 and HN-13. Material and Methods We examined the dynamic changes of early apoptosis and secondary necrosis in HN-30 and HN-13 cells treated by hyperthermia at 42°C for 10 min. We further examined mitochondrial membrane potential in vitro by ultrasound hyperthermia for different heating temperatures (38-44°C, 10 min) and heating times (42°C, 10-50 min). After heating by ultrasound at 42°C for 10 min, the apoptosis index achieved its highest level at 8 h after treatment, decreased rapidly and remained constant at a reduced level at 12 h. Results The level of secondary necrosis increased with the level of early apoptosis but remained at a higher level until 14 h. The level of secondary necrosis correlated with the level of early apoptosis (HN-13: r=0.7523, P=0.0030; HN-30: r=0.6510, P=0.016). The fractions of cells with low mitochondrial membrane potential (Δψ) in the heating-temperature grads group and heating-time grads group decreased significantly over time. Therefore, HN-30 and HN-13 cells developed apoptosis after ultrasound hyperthermia treatment with decreases in the mitochondrial transmembrane potential level. Conclusions Ultrasound hyperthermia induces apoptosis in HN-30 and HN-13 cells, possibly via the mitochondrial caspase pathway. Key words:Head and neck squamous cell carcinoma, apoptosis, mitochondrial membrane potential, ultrasound hyperthermia.

Abstract
Objective This article aims to determine the serological biomarkers which can be considered as risk factors of systemic lupus erythematosus (SLE)-associated pulmonary arterial hypertension by a systematic review and meta-analysis. Methods This study was conducted in accordance with the PRISMA statement. The search database included MEDLINE, EMBASE, Cochrane Library and Scopus. The Newcastle-Ottawa scale was used for the quality assessment. The odds ratio was the primary measure of effect of the risk factors. Results Twelve studies were included in this meta-analysis. The results identified the anti-RNP antibody and anti-Sm antibody as risk factors for SLE-associated pulmonary arterial hypertension with the pooled odds ratios 3.68 (95% confidence interval 2.04-6.63, P < 0.0001) and 1.71 (95% confidence interval 1.06-2.76, P = 0.03), respectively. Conclusion Pulmonary arterial hypertension is a serious complication of SLE with a worse prognosis than SLE patients without pulmonary arterial hypertension. The early recognition of pulmonary arterial hypertension with transthoracic echocardiography routinely performed in SLE patients with risk factors is necessary, especially in Asian patients.

Abstract
OBJECTIVES Regulatory factors controlling stem cell identity and self-renewal are often active in aggressive cancers and are thought to promote cancer growth and progression. B-cell-specific transcription factor 3 (TCF3/E2A) is a member of the T-cell factor/lymphoid enhancer factor (TCF/LEF) transcription factor family that is central to regulating epidermal and embryonic stem cell identity. It has been reported that TCF3 was connected with the development and progression of a number of human cancers. In this study, we aimed to identify the expression of TCF3 in human nasopharyngeal carcinoma (NPC) and evaluate its clinical significance. DESIGN To investigate the expression of TCF3 in NPC and its relationship to prognosis. SETTING An in vitro study. MAIN OUTCOME MEASURES We analysed the expression of TCF3 in NPC and in non-tumourous nasopharyngeal tissues by quantitative RT-PCR and Western blotting. The expression patterns of TCF3 in 117 archived paraffin-embedded NPC specimens were characterised by immunohistochemistry, and the correlation between the TCF3 protein expression and the clinicopathological features of NPC was analysed. RESULTS We observed that TCF3 had a higher expression in NPC than in non-tumourous nasopharyngeal tissues of 117 archived paraffin-embedded NPC specimens, and 80 (68.4%) biopsy tissues revealed high levels of TCF3 expression. Furthermore, statistical analyses demonstrated that the increased expression of TCF3 was closely related to clinical stage, locoregional recurrence and distant metastasis of NPC. NPC patients with high levels of TCF3 expression had a shorter survival time, whereas patients with lower levels of TCF3 expression survived longer. Moreover, multivariate analysis suggested that the upregulation of TCF3 was a critical prognostic factor for NPC. CONCLUSIONS Our observations suggest, for the first time, that TCF3 is significantly associated with the development and progression of NPC, which can be used as an important prognostic marker for patients with NPC and may be an effective target for the treatment of NPC.

A full-length cDNA encoding Cydia pomonella pheromone binding protein 1 (CpomPBP1) was cloned and characterized. CpomPBP1, possessing the typical characteristics of lepidopteran odorant binding proteins, was detected to be specifically expressed in the antennae of male and female moths at the mRNA and protein level. Soluble recombinant CpomPBP1 was subjected to in vitro binding to analyse its binding properties and to search for potentially active semiochemicals. A competitive binding assay showed that three 12-carbon ligands, codlemone, 1-dodecanol and E,E-2,4-dodecadienal, were able to bind to CpomPBP1 in decreasing order of affinity. Moreover, unlike the wild-type CpomPBP1, the C-terminus truncated CpomPBP1 exhibited high affinity to ligands even in an acidic environment, suggesting that the C-terminus plays a role in preventing ligands from binding to CpomPBP1 in a lower pH environment.

Abstract
We present an angle-resolved photoemission study of the electronic structure of the three-dimensional pyrochlore iridate Nd_{2}Ir_{2}O_{7} through its magnetic metal-insulator transition. Our data reveal that metallic Nd_{2}Ir_{2}O_{7} has a quadratic band, touching the Fermi level at the Γ point, similar to that of Pr_{2}Ir_{2}O_{7}. The Fermi node state is, therefore, a common feature of the metallic phase of the pyrochlore iridates. Upon cooling below the transition temperature, this compound exhibits a gap opening with an energy shift of quasiparticle peaks like a band gap insulator. The quasiparticle peaks are strongly suppressed, however, with further decrease of temperature, and eventually vanish at the lowest temperature, leaving a nondispersive flat band lacking long-lived electrons. We thereby identify a remarkable crossover from Slater to Mott insulators with decreasing temperature. These observations explain the puzzling absence of Weyl points in this material, despite its proximity to the zero temperature metal-insulator transition.
