Abstract
Objective: To explore the feasibility and efficacy of radiofrequency coblation assisted transoral surgery for the treatment of supraglottic laryngeal carcinoma by comparing with concurrent patients treated with conventional transcervical approach. To clarify the advantages of different surgical methods and to summarize the experience of supraglottic carcinoma radiofrequency ablation. Methods: Forty-six patients with supraglottic laryngeal carcinoma treated in department of otorhinolaryngology head and neck surgery, Peking University First Hospital from March 2014 to January 2021 were analyzed retrospectively. Among them(43 males, 3 females, aged from 45 to 79 years old), 23 patients were treated with radiofrequency coblation and 23 patients with partial laryngectomy with conventional transcervical approach. The operation time, intra-operative blood loss volume, recovery time, inpatient total medical cost and follow-up information of the two groups were analyzed. SPSS 26.0 software was used for statistical analysis. Results: There were no significant differences in age, gender, TNM staging,tumor staging and postoperative radiotherapy between the two groups (all P>0.05).The operation time, intra-operative blood loss volume, recovery time, inpatient total medical cost of the RFC-TOS group were110.0(60.0,150.0)min,5.0(5.0,30.0)ml,3.0(2.0,5.0)days,6.0(4.0,14.0)days and 26 100.7(16 145.5,47 044.4)yuan. The data of conventional transcervical approach group were 205.0(156.5,272.3)min, 150.0(50,200) ml, 18.0(16.3,22.8)days and 56520.1(440 992.5,67 109.9)yuan, (Z=-4.03, -4.94, -4.97, -4.98 and -4.13;all P<0.001).The 5-year local control rate, disease-specific survival rate and overall survival rate of the two groups were 86.96%,95.65%,91.30% and 86.96%,91.30%,73.90% renspectively, which had no significant difference between the two groups(all P>0.05).

Abstract
Resistin is upregulated in obese humans and mice, and elevated serum resistin induces insulin resistance and hepatic steatosis. Previous studies have revealed that mulberry 1-deoxynojirimycin (DNJ) is important for a variety of physiological processes, especially carbohydrate and lipid metabolism. However, it remains unclear whether DNJ has a positive effect on insulin resistance and hepatic steatosis, and what the exact mechanism is. Male C57BL/6J mice were treated with resistin with or without DNJ. DNJ reversed the homeostasis model assessment of insulin resistance (HOMA-IR)-induced by resistin and significantly decreased triglyceride levels both in the serum and liver. A histological analysis demonstrated that lipid accumulation significantly decreased in the DNJ group compared to the resistin group. A mechanistic analysis showed that DNJ significantly inhibited the resistin-induced decline in enzyme activities of hormone-sensitive lipase (HSL) and hepatic lipase (HL) in serum and lipoprotein lipase (LPL) in liver. FAS and Acox13α were significantly altered by resistin but restored by DNJ. Furthermore, DNJ partially but significantly restored insulin-stimulated glucose uptake compared with the resistin group, suggesting that DNJ reversed the insulin sensitivity impaired by hyperresistinemia. Treatment of AML12 cells with DNJ significantly restored the expression level and phosphorylation of Akt. The transcriptional levels of InsR and IRS1, as well as the protein levels of InsR and Glut4 and phosphorylation of PI3K and GSK3β, were also normalized in the DNJ-treated group. In conclusion: mulberry DNJ significantly alleviated liver steatosis and insulin resistance in hyperresistinemia.

Abstract
AIMS The EMPOWER-Lung 1 trial showed that cemiplimab significantly prolongs the duration of progression-free survival and overall survival in advanced non-small cell lung cancer (NSCLC) patients with at least 50% programmed cell death receptor ligand-1 (PD-L1) positivity, yet the financial burden may limit its use. The aim of the present study was to evaluate the cost-effectiveness of cemiplimab versus chemotherapy in a US setting. MATERIALS AND METHODS A Markov model, with three mutually exclusive health states, was used to compare the expected health outcomes and cost of cemiplimab with chemotherapy. Survival data and transition probabilities were collected from the EMPOWER-Lung 1 trial. Utility values and costs are publicly available from open sources. One-way and probabilistic sensitivity analyses were conducted in both the whole population and subgroups to test the robustness of the parameters and structure. RESULTS Treatment of NSCLC with cemiplimab yielded an extra 1.07 quality-adjusted life years (QALYs) at an additional cost of $98 211 compared with chemotherapy, associated with an incremental cost-effectiveness ratio of $91 891/QALY and an incremental net health benefit of 0.087 QALYs at a willingness to pay threshold of $100 000/QALY. The probabilistic sensitivity analysis indicated that cemiplimab provided an 83.2% probability of being cost-effective. One-way sensitivity analysis suggested that the price of cemiplimab was the chief driver in this model. A subgroup analysis showed that cemiplimab was the preferred incremental net health benefit in more than half of the subgroups, including patients with squamous type disease and metastases. CONCLUSIONS Cemiplimab is a cost-effective option in the first-line treatment of NSCLC in patients who are at least 50% PD-L1 positive from an American perspective.

Abstract
<p>Coccidiosis is a major disease caused by various <em>Eimeria</em> species in rabbits. The aim of the present study was to investigate the haematological and pathological changes in rabbits infected with <em>E. magna</em>. Moreover, the localisation of coccidial antigens was examined in the intestines of rabbits with two kinds of serum as primary antibodies. In the present study, forty-five 28-day-old weaned rabbits were randomly divided into three groups and reared in three separate places. Group A was infected with 20×10<sup>3</sup> sporulated oocysts of <em>E. magna</em>, group B was only used to produce anti-<em>E. intestinalis</em> serum by infecting them with 3×10<sup>3</sup> sporulated oocysts of <em>E. intestinalis</em>, and group C was designated as the control group. According to histopathological evaluation of group A, the epithelial cells of the jejunum and ileum were parasitised with a large number of oocysts and other stages of <em>E. magna</em>. The haematological results showed that red blood cell counts, haemoglobin counts, haematocrit levels and the percentage of lymphocytes were significantly decreased in group A compared with group C (<em>P</em><0.01), but white blood cell counts and the percentage of neutrophils were significantly increased (<em>P</em><0.01). The weight of group A began to decrease on the 5<sup>th</sup> day after infection, and this decrease continued until the 9th day. Immunohistochemistry staining revealed that two kinds of coccidial antigens were basically located at the same sites of the intestine when anti-<em>E. intestinalis</em> serum and anti-<em>E. magna</em> serum were used as primary antibodies. Most likely, <em>E. magna</em> and <em>E. intestinalis</em> antigens have some similar antigenic determinants; this finding provides a theoretical basis for screening for common antigens of these two coccidian species.</p>

Abstract
Microwave reflectometry diagnostics have been widely used to measure density profiles in fusion plasma. However, the high sensitivity of the diagnostics to plasma turbulence often results in large radial deviations in the edge density profile and causes difficulty in profile evaluation. To improve the performance of profile evaluation, a modified RANdom SAmple Consensus (RANSAC) method has been applied to fit the density profiles measured by reflectometry on the experimental advanced superconducting tokamak. Compared with the traditional least-squares method, the modified RANSAC method is much more efficient and robust in fitting the experimental profiles. Furthermore, a combination of RANSAC and a genetic algorithm (GA-RANSAC) is used to further optimize the profile evaluation procedure. The results show that this GA-RANSAC method yields better performance and stabler convergence than the modified RANSAC alone.

Abstract
MnO2 based electrochemical enzyme-free glucose sensors remain significantly limited by their low electronic conductivity and associated complex preparation. In this paper, an MnO2 nanosheet array supported on nickel foam (MnO2 NS/NF) was prepared using a simple hydrothermal synthesis and employed as a 3D integrated electrode for enzyme-free glucose detection. It was found that MnO2 NS/NF shows high performance with a wide linear range from 1 μM to 1.13 mM, a high sensitivity of 6.45 mA mM-1 cm-2, and a low detection limit of 0.5 μM (S/N = 3). Besides, MnO2 NS/NF shows high selectivity against common interferences and good reliability for glucose detection in human serum. This work demonstrates the promising role of MnO2 NS/NF as an efficient integrated electrode in enzyme-free glucose detection with high performance.

Abstract
UNLABELLED By Bayesian random effects network meta-analysis stratified by prevalent vertebral fracture (PVF), we conclude that different effective drugs should be used to prevent fragility fractures according to postmenopausal women with or without PVF and that there are two drugs (i.e., parathyroid hormone (1-84) and abaloparatide) less tolerated than placebo. INTRODUCTION No studies have compared various osteoporosis drugs in postmenopausal women (PMW) either with or without prevalent vertebral fracture (PVF). We aimed to compare them in the two different subgroups. METHODS We searched different databases to select relevant studies. We performed Bayesian random effects network meta-analysis to synthesize hazard ratio (HR) and 95% confidence interval (CI) for clinical fracture stratified by PVF and to synthesize risk ratio (RR) for tolerability and vertebral fracture. RESULTS We included 33 trials involving 79,144 PMW. In the PVF ≥ 50% subgroup, teriparatide (HR 0.39, 95% CI 0.28-0.57), romosozumab (HR 0.49, 95% CI 0.29-0.75), risedronate (HR 0.62, 95% CI 0.50-0.79), zoledronate (HR 0.67, 95% CI 0.47-0.96), and alendronate (HR 0.69, 95% CI 0.47-0.97) reduced clinical fracture risk. In the other subgroup, abaloparatide (HR 0.56, 95% CI 0.33-0.92), romosozumab (HR 0.67, 95% CI 0.47-0.95), and denosumab (HR 0.68, 95% CI 0.50-0.85) reduced clinical fracture risk. Five drugs reduced vertebral fracture risk in the PVF ≥ 50% subgroup whereas seven did in the other subgroup. All drugs did not increase withdrawal risk except for parathyroid hormone (1-84) (PTH) (RR 1.9, 95% CI 1.4-2.6) and abaloparatide (RR 1.6, 95% CI 1.2-2.3). CONCLUSION Different effective drugs should be used to prevent fragility fractures according to PMW with or without PVF, and romosozumab is the only one which can reduce clinical and vertebral fractures in both of the two populations. PTH and abaloparatide are less tolerated than placebo whereas the eight other drugs assessed in the study have the same tolerability as placebo.

Abstract
Objective: To clarify the effect of cognitive impairment on social function and quality of life of chronic schizophrenia, and provide clinical cognitive strategies for improving the social function and quality of life of patients with schizophrenia. Methods: Atotal of 158 patients with chronic schizophrenia were selected from May 2017 to October 2017 in the Psychiatry Department of the Third Affiliated Hospital of Sun Yat-sen University received psychological assessments, such as, MATRICS Consensus Cognitive Battery(MCCB), the Brief Psychiatric Rating Scale(BPRS), the Personal and Social Performance scale(PSP), and Schizophrenia Quality of Life Scale(SQLS). We further explored the effects of neurocognitive and social cognitive functions on their individual and social performance and quality of life in patients with schizophrenia. Results: (1) The scores of SQLS in the group with impaired social cognitive function were higher than those with good social function(101±46 vs 76±40, P=0.002). (2) The digital sequence and continuous performance test of the socially functional group were higher than the defect group. (3) There was a significant correlation between the years of education(R(2)=0.334, F=25.542), continuous performance (R(2)=0.316, F=35.647), BPRS (R(2)=0.280, F=60.386) and social function (P<0.001). (4) BPRS (R(2)=0.486, F=228.28), and emotional management (MSCEIT) (R(2)=0.510, F=124.789), education (R(2)=0.531, F=90.161), age (R(2)=0.539, F=69.644) significantly affected the SQLS score of patients with schizophrenia(P<0.001). Conclusion: The social function and quality of life of patients with schizophrenia are significantly correlated with their years of education and disease severity. Continuous performance in neurocognition significantly affects the social function of patients with schizophrenia, and emotional management in social cognition significantly affects their quality of life. Socially functional schizophrenia patients have higher digital sequences (working memory) and continuous performance (attention/alertness) scores.

Abstract
Triglyceride (TG) and fatty acid profiles of raw (RM), pasteurized (PM, 85°C for 15 s), and indirect UHT-treated (UM, 135°C for 15 s) cow milk were investigated by a lipidomics approach. Ninety-four TG were identified and all were present at significantly lower concentrations in UM than in RM or PM, and free fatty acid contents were significantly higher in UM than in RM and PM, indicating that TG lipolysis occurred to a greater degree in UM than in RM and PM. In addition, UM contained significantly fewer unsaturated fatty acids (14 types) than those in RM and PM, including C14:1n-5, C15:1n-5, C16:1n-7, C17:1n-7, C18:1n9 cis, C18:2n-6 cis, C18:3n-3, C18:3n-6, C20:1, C20:2, C20:3n-6, C20:3n-3, C20:4n-6, and C20:5n-3. However, we detected no significant differences between RM and PM in these fatty acids. In conclusion, UHT treatment, but not pasteurization, caused loss of the nutritional quality and bioactivity of cow milk lipid profiles.

Abstract
We developed a sensitive and selective isotope dilution ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the determination of sulbactam residue in raw bovine milk. Sulbactam and internal standard, sulbactam-d5, were extracted from raw bovine milk via liquid-liquid extraction and enriched with strong anion exchange solid-phase extraction cartridges and finally analyzed by using UPLC-MS/MS with multiple reaction monitoring mode. The method was validated according to European regulations. The calibration curve showed good linearity, with a correlation coefficient of 0.9998. Decision limit and detection capability of sulbactam were determined by matrix calibration curve and were 0.0445 and 0.0517 μg/L, respectively. The recoveries of sulbactam in fortified raw bovine milk ranged from 72.1 to 91.5%, with the intra- and interday relative standard deviations ranging from 3.0 to 18.9%. Furthermore, the developed method was applied to analyzing real raw bovine milk samples collected from dairy farms in Beijing, China. Sulbactam was not determined in all samples. The proposed method could ultimately serve as a methodological foundation for the determination of sulbactam in different types of raw milk and dairy products.

Abstract
Isopentenylation at A37 (i6 A37) of some transfer RNAs (tRNAs) plays a vital role in regulating the efficiency and fidelity of protein synthesis. However, whether insects, which are well known for their highly efficient protein synthesis machinery, employ this regulatory mechanism remains uninvestigated. In the current study, a candidate tRNA isopentenyltransferase (IPT) gene with three alternative splicing isoforms (BmIPT1-BmIPT3) was identified in Bombyx mori (silkworm). Only BmIPT1 could complement a yeast mutant lacking tRNA IPT. Phylogenetic analysis showed that silkworm tRNA IPT is conserved in the Lepidoptera. BmIPT was expressed in all B. mori tissues and organs that were investigated, but was expressed at a significantly higher level in silk glands of the fourth instar compared to the first day of the fifth instar. Interestingly, BmIPT was expressed at a significantly higher level in the domesticated silkworm, B. mori, than in wild Bombyx mandarina in multiple tissues and organs. Knock-down of BmIPT by RNA interference caused severe abnormalities in silk spinning and metamorphosis. Constitutive overexpression of BmIPT1 using a cytoplasmic actin 4 promoter in B. mori raised its messenger RNA level more than sixfold compared with nontransgenic insects and led to significant decreases in the body weight and cocoon shell ratio. Together, these results confirm the first functional tRNA IPT in insects and show that a suitable expression level of tRNA IPT is vital for silk spinning, normal growth, and metamorphosis. Thus, i6 A modification at position A37 in tRNA probably plays an important role in B. mori protein synthesis.

Abstract
PURPOSE The aim of the study was to evaluate the cost-effectiveness of capecitabine plus bevacizumab compared with capecitabine alone in elderly patients with metastatic colorectal cancer (CRC) from a Chinese societal perspective. METHODS A decision-analytic Markov model was conducted to simulate the process of metastatic CRC. Three distinct health states: progression-free survival (PFS), progressive disease and death were included. Clinical data were derived from the AVEX trial. Health effectiveness was denoted in quality-adjusted life years (QALYs) and health utilities were derived from previously published studies. Incremental cost-effectiveness ratio (ICER) was regarded as the primary endpoint and willingness-to-pay (WTP) threshold was set at $26,753.37/QALY (3 × per capita GDP of China, 2017). One-way sensitivity analyses and probabilistic sensitivity analysis were also performed to explore the parameters uncertainty in the study. RESULTS Over a 10-year life horizon, capecitabine plus bevacizumab gained 1.14 QALYs at an average cost of $21,609.48, while the effectiveness and cost of capecitabine group were 0.99 QALYs and $7274.83, respectively. The ICER between the two groups was $95,564.33/QALY. Parameters that mostly influenced the results of the model were utility of PFS state, duration of PFS state for capecitabine plus bevacizumab, total cost of PFS state for capecitabine plus bevacizumab and price of bevacizumab. The probabilities of capecitabine plus bevacizumab and capecitabine as the dominant option were 0% and 100% at the WTP threshold of $26,753.37/QALY. CONCLUSIONS The results of the study showed that capecitabine plus bevacizumab is unlikely to be a cost-effective treatment option for elderly patients with metastatic CRC.

Abstract
Objective:To summarize and analyze the clinical features, diagnosis methods, surgical approaches and treatment outcomes of patients with parapharygeal space tumors.Method:A retrospective review of 72 cases with parapharygeal space tumors treated from March 1994 to June 2017 was performed. The data on presentation, surgical approach, histological diagnosis and postoperative complications were reviewed.Result:The postoperative pathological diagnosis included 62 benign tumors and 10 malignant tumors. The most frequent symptom was a cervical mass or an intraoral swelling. All patients underwent preoperative enhanced CT scan or MRI,which would be helpful to evaluate the tumor sizes,locations and possible sources,and to make operation scheme. The postoperative pathology included 24 salivary gland lesions and 30 neurogenic lesions. The postoperative complications happened in 13 patients. The surgical approaches included trans-cervical approach in 55 cases, cervical-parotid approach in 9 cases,trans-oral approach in 6 cases , and trans skull base approach in 2 case.Conclusion:A parapharygeal space tumor is an uncommon tumor and requires careful preoperative assessment. Surgery is the first choice for parapharygeal space tumors. These patients should be counseled appropriately about the potential for permanent cranial nerve deficits.

Abstract
An ordinary-mode polarized multi-channel correlation reflectometer has been developed on the Experimental Advanced Superconducting Tokamak (EAST). The system with four different probing frequencies (i.e., 20.4 GHz, 24.8 GHz, 33 GHz, and 40 GHz) and two poloidally spaced receiving antennas can realize both the radial correlation measurement and the poloidal correlation measurement. These diagnostics focus on the measurement of density fluctuation in the pedestal region to investigate the turbulence transport and H-mode physics on EAST. In this article, the system hardware design, the key component tests, and the system performance are shown in detail.

Abstract
We experimentally demonstrate all-optical amplitude regeneration of 4-level pulse amplitude modulated signals (PAM4) based on a single nonlinear optical loop mirror (NOLM). Four power-plateau regions are achieved using return-to-zero (RZ) pulses of narrow pulse-width, enabling large nonlinear phase shifts within the highly nonlinear fiber (HNLF). We quantify noise suppression characteristics at each amplitude level and obtain an overall EVM improvement of 0.92dB by optimizing input power and distortion strength. A theoretical analysis has been also carried out matching the experimental results and revealing the design characteristics of the regenerator's nonlinear transfer function.

Abstract
BACKGROUND The BEYOND trial found that the addition of bevacizumab (B) to paclitaxel-carboplatin (PC) chemotherapy provided a significant clinical benefit to Chinese patients with metastatic non-squamous non-small-cell lung cancer (NSCLC). This study aimed to evaluate the cost-effectiveness of adding B to first-line PC induction and continuation maintenance therapy from a Chinese perspective. METHODS A Markov model was developed to estimate the cost and effectiveness of B + PC in the induction and maintenance therapy of patients with metastatic non-squamous NSCLC. Costs were calculated in the Chinese setting, and health outcomes derived from the BEYOND trial were measured as quality-adjusted life years (QALYs). A one-way sensitivity analysis was conducted to explore the impact of various parameters in the study. RESULTS The B + PC treatment was more costly ($112,943.40 versus $32,171.43) and more effective (1.07 QALYs versus 0.80 QALYs) compared with the PC treatment. Adding B to the PC regimen for non-squamous NSCLC results in an incremental cost-effectiveness ratio of $299,155.44 per QALY, which exceeded the accepted societal willingness-to-pay threshold ($23,970.00) for China. In the sensitivity analysis, the duration of progression-free survival (PFS) for the B + PC group, the cost of the PFS state for B + PC group and the price of B were considered the most sensitive factors in the model. CONCLUSIONS The addition of B to first-line PC induction and maintenance therapy was not determined to be a cost-effective strategy for metastatic non-squamous NSCLC in China, even when an assistance program was provided.

Abstract
Hydrogen sulfide (H2S), a gasotransmitter, has been recently linked to mesenchymal stem cell (MSC) function and bone homeostasis. Periodontal ligament stem cells (PDLSCs) are the main MSCs in PDL, which respond to mechanical force to induce physiological activities during orthodontic tooth movement (OTM). However, it is unknown whether mechanical force might induce endogenous H2S production by PDLSCs to regulate alveolar bone homeostasis. Here, we used a mouse OTM model to demonstrate that orthodontic force-induced endogenous H2S production in PDL tissue was associated with macrophage accumulation and osteoclastic activity in alveolar bone. Then, we showed that mechanical force application induced cystathionine β-synthase (CBS) expression and endogenous H2S production by PDLSCs. Moreover, blocking endogenous H2S or systemically increasing H2S levels could decrease or enhance force-induced osteoclastic activities to control tooth movement. We further revealed how force-induced H2S production by PDLSCs contributed to the secretion of monocyte chemoattractant protein-1 (MCP-1) and the expression of receptor activator of nuclear factor-κB ligand/osteoprotegerin (RANKL/OPG) system by PDLSCs. The secretion and expression of these factors controlled macrophage migration and osteoclast differentiation. This study demonstrated that PDLSCs produced H2S to respond to and transduce force signals. Force-induced gasotransmitter H2S production in PDLSCs therefore regulated osteoclastic activities in alveolar bone and controlled the OTM process through the MCP-1 secretion and RANKL/OPG system.

Abstract
Aims Resistin has been reported to impair the pancreatic beta cells and associated with insulin resistance. MicroRNAs (miRNAs) are short, endogenously produced non-coding ribonucleotides that bind mRNAs and function mainly as negative regulators in mammals. MiRNAs have been implicated in many diseases, including insulin resistance and diabetes. A considerable body of evidence has indicated an important function for miRNAs in insulin secretion. The current study was designed to investigate the effects of miR-494 in the reductions in insulin secretion attributable to resistin. Methods Insulin secretion was determined by ELISA, and expressions of genes were identified using quantitative RT-PCR (qRT-PCR) or Western blot analysis. Results Insulin secretion was significantly reduced by resistin. Overexpression of miR-494 inhibited insulin secretion both in diet culture and high glucose medium in MIN6 cell lines. MiR-494 down-regulated the protein level of STXBP5 by pairing with sites in the 3'UTR. Conclusion miR-494 is involved in the insulin secretion regulated by resistin via its effects on STXBP5 in MIN6 cells.

Abstract
A new multi-channel poloidal correlation reflectometry is developed at Experimental Advanced Superconducting Tokamak. Eight dielectric resonator oscillators with frequencies of 12.5 GHz, 13.5 GHz, 14.5 GHz, 15 GHz, 15.5 GHz, 16 GHz, 17 GHz, and 18 GHz are used as sources. Signals from the sources are up-converted to V band using active quadruplers and then coupled together. The output waves are launched by one single antenna after passing through a 20 dB directional coupler which can provide the reference signal. Two poloidally separated antennae are installed to receive the reflected waves from plasma. The reference and reflected signals are down-converted by mixing with a quadrupled signal from a phase-locked source with a frequency of 14.2 GHz and the IF signals pass through the filter bank. The resulting signals from the mixers are detected by I/Q demodulators. The setup enables the measurement of density fluctuation at 8 (radial) × 2 (poloidal) spatial points. A coherent mode with an increasing velocity from 50 kHz to 100 kHz is observed by using the system. The mode is located in the steep gradient region of the pedestal.

Abstract
The E3805 (CHAARTED) study found that docetaxel combined with androgen-deprivation therapy (ADT) significantly improved overall survival of patients with metastatic hormone-sensitive prostate cancer. This study aims to determine whether docetaxel combined with ADT is a cost-effective strategy for advanced prostate cancer in China. According to the E3805 study, two groups (docetaxel + ADT and ADT alone) and three health states [progression-free survival (PFS), progressive disease (PD) and death] were analysed in a Markov model. All medical costs were calculated from the Chinese societal perspective. Quality-adjusted life year (QALY) and incremental cost-effectiveness ratios (ICERs) were applied as the primary outcome. Overall, the addition of docetaxel was estimated to increase the cost by $12 816.93, with a gain of 0.48 QALY. Additionally, for patients with high-volume disease, the increased cost and effectiveness were $14 627.75 and 0.69 QALYs in docetaxel + ADT group versus the ADT alone group, and the ICER was $21 199.63 per QALY. These ICERs are far more than the commonly accepted willingness-to-pay (WTP) threshold of $20 301 per QALY in China. In spite of longer survival time, docetaxel combined with ADT is not a recommended cost-effective treatment for metastatic hormone-sensitive prostate cancer in the Chinese setting.

Abstract
BACKGROUND The development of vitrification strategy for cell-biomaterial constructs, particularly biologically inspired nanoscale materials and hydrogels mimicking the in vivo environment is an active area. A cryopreservation strategy mimicking the in vivo environment for cell-hydrogel constructs may enhance cell proliferation and biological function. OBJECTIVE To demonstrate the efficacy of vitrification as a platform technology involving tissue engineering and human mesenchymal stem cells (hMSCs). MATERIALS AND METHODS Microcarriers made from alginate coated with chitosan and collagen are used. Conventional freezing and vitrification were compared. The vitrification strategy includes 10 min step-wise exposure to a vitrification solution (40% v/v EG, 0.6M sucrose) and immersion into liquid nitrogen. RESULTS Confocal imaging of live/dead staining of hMSCs cultured on the surface of microcarriers demonstrated that vitrified cells had excellent appearance and prolonged spindle shape morphology. The proliferation ability of post-vitrified cells arbitrated to protein Ki-67 gene expression was not significantly different in comparison to untreated control, while that of post-freezing cells was almost lost. The ability of hMSCs cultured on the surface of microcarriers to proliferate has been not affected by vitrification and it was significantly better after vitrification than after conventional freezing during continuous culture. Collagen II related mRNA expression by 4 weeks post-vitrification and post-freezing showed that ability to differentiate into cartilage was sustained during vitrification and reduced during conventional freezing. No significant difference was found between control and vitrification groups only. CONCLUSION Vitrification strategy coupled with advances in hMSC-expansion platform that completely preserves the ability of stem cells to proliferate and subsequently differentiate allows not only to reach a critical cell number, but also demonstrate prospects for effective utilization and transportation of cells with their support system, creating demand for novel biodegradable materials.

Abstract
Vitamin D-binding protein (DBP), a highly polymorphic serum protein, encoded by GC gene, is important in the development of chronic obstructive pulmonary disease (COPD). This meta-analysis was performed to assess the association between GC polymorphisms (1F, 1S, and 2 alleles) and COPD susceptibility. Published case-control studies were retrieved from the Pubmed, Embase, and China National Knowledge Infrastructure databases. After data extraction, pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Seven case-control studies were included. Pooled effect size showed that GC polymorphisms were not significantly associated with COPD susceptibility. According to ethnicity, the 1F allele was significantly correlated with COPD susceptibility in Asians (1F vs 1S, OR: 1.52, 95%CI: 1.16-2.00 and 1F vs 2, OR: 1.87, 95%CI: 1.42-2.44), indicating that individuals with the 1F allele have an increased risk of COPD compared to those with the 1S or 2 allele. However, the 1F allele was associated with a lower, insignificant risk of COPD than the 1S and 2 alleles in Caucasians (1F vs 1S, OR: 0.83, 95%CI: 0.64-1.08 and 1F vs 2, OR: 0.73, 95%CI: 0.54-0.98). Moreover, no significant association was found for the 1S and 2 alleles in Asians (OR: 1.23, 95%CI: 0.90- 1.69) and Caucasians (OR: 0.89, 95%CI: 0.70-1.13). After excluding each study, the pooled results were robust and no publication bias was observed. We found that the GC 1F allele confers a risk of COPD in Asians, whereas the 1F allele may protect against COPD in Caucasians.

Abstract
OBJECTIVES The objective was to explore clinical effect of limited resection of lung lobe under the thoracoscopy in the treatment of early nonsmall cell lung cancer occurred in the old age. METHODS A total of 150 patients with nonsmall cell lung cancer in the old age is treated by limited resection of lung lobe under thoracoscope. It can be divided into segmental resection group and wedge resection group by surgical methods, to make a comparative analysis of operation time, intraoperative blood loss, hospital stays, and complications during the perioperative period. And there will be postoperation follow-up on survival, relapse and death situation etc., RESULTS 10 cases are changed to make other operation because of maladaptation to limited resection, and a total of 140 patients have undergone limited resection. Operation time and hospital stays of wedge resection group are shorter than those of segmental resection group (P < 0.05); compared with the bleeding and indwelling drainage tube time in two groups, differences have no statistical significance (P > 0.05). Compared with cases of complications, recurrence and death for groups of segmental resection and wedge resection group, the differences have no statistical significance (P > 0.05). CONCLUSION Limited resection of lung lobe in the early treatment of nonsmall cell lung cancer occurred in the old age under the thoracoscopy is safe and feasible.

Abstract
In this study, a sensitive and rapid method has been developed for the simultaneous determination of aflatoxin M1, ochratoxin A, zearalenone and α-zearalenol in milk by ultra high performance liquid chromatography combined with electrospray ionisation triple quadrupole tandem mass spectrometry (UHPLC-ESI-MS/MS). The milk samples were purified using Oasis HLB cartridge. The matrix effects were evaluated by determining the signal suppression-enhancement (SSE) and corrected by external matrix-matched calibration. The limits of quantity (LOQ) of the mycotoxins were in the range of 0.003-0.015μgkg(-1). The high correlation coefficients (R(2)⩾0.996) were obtained in the range of 0.01-1.00μgkg(-1) of the mycotoxins, along with good recovery (87.0-109%), repeatability (3.4-9.9%) and intra-laboratory reproducibility (4.0-9.9%) at the concentrations of 0.025, 0.1 and 0.5μgkg(-1). The detected rates of the mycotoxins were from 16.7% to 96.7% in raw milk, liquid milk and milk powder samples collected from the dairy farms and supermarkets in Beijing. The method proposed is suitable for the simultaneous determination of aflatoxin M1, ochratoxin A, zearalenone, and α-zearalenol, and could be performed for analysing the mycotoxins in milk.

Abstract
AIM XELOX and FOLFOX4 have both been recommended as adjuvant therapy for stage III colon cancer. This study compared the two regimens in terms of monetary costs, assuming equal efficacy of the therapies. METHOD A retrospective financial audit was conducted of the medical records of patients treated with XELOX or FOLFOX4. All itemized expenses were classified as direct (chemotherapy, hospitalization, venous access and tests), related to adverse effects due to the adjuvant therapy, or societal (travel and time costs). The cost of supportive care was not included. RESULTS XELOX involved less total cost to the patient than FOLFOX4 (a difference of US$2857.68), fewer costs related to adverse effects ($668.97), and less travel ($26.07) and time ($390.93) expenditure per patient. CONCLUSION The results indicate that, overall, XELOX is a more affordable option than FOLFOX4 in China.

Abstract
Immunotherapy that is based on adoptive transfer of T lymphocytes, which are genetically modified to express chimeric antigen receptors (CARs) that recognize tumor-associated antigens, has been demonstrated to be an efficient cancer therapy. Vascular endothelial growth factor receptor-1 (VEGFR-1), a vital molecule involved in tumor growth and angiogenesis, has not been targeted by CAR-modified T lymphocytes. In this study, we generated CAR-modified T lymphocytes with human VEGFR-1 specificity (V-1 CAR) by electroporation. V-1 CAR-modified T lymphocytes were demonstrated to elicit lytic cytotoxicity to target cells in a VEGFR-1-dependent manner. The adoptive transfer of V-1 CAR T lymphocytes delayed tumor growth and formation and inhibited pulmonary metastasis in xenograft models and such efficacies were enhanced by cotransfer of T lymphocytes that expressed interleukin-15 (IL-15). Moreover, V-1 CAR-modified T lymphocytes lysed primary endothelial cells and impaired tube formation, in vitro. These data demonstrated the antitumor and anti-angiogenesis ability of V-1 CAR-modified T lymphocytes. Our study provides the rationale for the clinical translation of CAR-modified T lymphocytes with VEGFR-1 specificity.

Abstract
Malignant ascites is common in various types of cancers and is difficult to manage. Vascular endothelial growth factor (VEGF) has a pivotal role in malignant ascites. The matrix protein of vesicular stomatitis virus (VSVMP) has been shown to inhibit host gene expression and induce the apoptosis of cancer cells. The present study was designed to determine whether VSVMP suppresses the formation of ascites in ascites-producing peritoneal carcinomatosis. BALB/c female mice, 6-8 weeks old, bearing peritoneal tumors of H22 or MethA cells received an intraperitoneal administration of 50 μg VSVMP/250 μg liposome complexes, 50 μg empty plasmid/250 μg liposome complexes or 0.9% NaCl solution, respectively, every 2 days for 3 weeks. Administration of VSVMP resulted in a significant inhibition in ascites formation, improvement in health condition and prolonged survival of the treated mice. Decreased peritoneum osmolarity and reduced tumor vascularity coincided with dramatic reductions in the VEGF level in ascites fluid and plasma. Examination of floating tumor cells collected from the peritoneal wash revealed an apparently increased number of apoptotic cells and profound downregulation of VEGF mRNA in the VSVMP-treated mice. Our data indicate for the first time that in BALB/c mice bearing H22 or MethA cell peritoneal tumors, VSVMP may inhibit VEGF production and suppress angiogenesis, consequently abolishing ascites formation.

Abstract
BACKGROUND Oxaliplatin-related neurotoxicity is the main limitation for its continuation in adjuvant and palliative chemotherapy for patients with colorectal cancer. The purpose of this meta-analysis was to determine the efficacy of calcium and magnesium (Ca/Mg) infusions in oxaliplatin-induced neurotoxicity. METHODS Two independent authors conducted database searches of the literature to find clinical-controlled trials analyzing Ca/Mg infusions in oxaliplatin-induced neurotoxicity. The keywords used to search were oxaliplatin, neurotoxicity, calcium, magnesium, neuropathy, and peripheral. Clinical studies that included at least one primary or secondary event were eligible for the analysis, where primary events were incidences of acute and cumulative neurotoxicity, and secondary events were the total doses and cycles of oxaliplatin, response rate (RR), overall survival (OS), and progression-free survival (PFS). Odds ratios (ORs) and weighted mean differences (MD) were analyzed using models of fixed and random effects. RESULTS This meta-analysis comprised four prospective randomized clinical trials and three retrospective clinical trials involving 1170 colorectal cancer patients, of which 802 received Ca/Mg infusions (Ca/Mg group) and 368 did not (control group). According to the National Cancer Institute-Common Terminology Criteria for Adverse Events, the incidence of grade 3 acute neurotoxicity in those who received Ca/Mg was significantly lower than that of the control group (OR=0.26; 95% confidence interval (CI), 0.11 to 0.62; P=0.0002). The total rate of cumulative neurotoxicity, and that of grade 3 in particular, was significantly lower in the Ca/Mg group than in the control group (OR=0.42; 95% CI 0.26-0.65; P=0.0001; OR=0.60; 95% CI 0.39-0.92; P=0.02, respectively). The differences in total doses and cycles of oxaliplatin were also significant between the Ca/Mg and control group (MD=246.73 mg/m2; 95% CI 3.01-490.45; P=0.05; MD=1.55; 95% CI 0.46-2.63; P=0.005, respectively). No significant differences were found in median PFS (MD=0.71 month; 95% CI -0.59-2.01; P=0.29), median OS (MD=0.10 month; 95% CI -0.41-0.61; P=0.70) or RRs (OR=0.82; 95% CI 0.61-1.10; P=0.18). CONCLUSION Ca/Mg infusions tend to decrease the incidence of oxaliplatin-induced acute and cumulative neurotoxicity and thus enhance patients' tolerance to oxaliplatin, without significantly altering the efficacy of chemotherapy.

Abstract
The complete RNA genome sequences of 10 tobacco vein banding mosaic virus (TVBMV) isolates from China were determined using five overlapping cDNA clones. TVBMV was divided into three groups for HC-Pro and CP and into two groups for P3 and 6K1. With more isolate sequences analyzed, the phylogenetic results suggest that TVBMV could be divided into four subgroups based on HC-Pro and CP and into three subgroups with P3 and 6K1. Nucleotide sequence diversity analysis showed geographical differentiation among the TVBMV isolates. Three of the 10 isolates were found to have undergone recombination and new recombination sites were identified in the TVBMV genome. All coding genes were under negative selection and the population appeared to have remained stable over a long period. This study also provides preliminary data on the 3´-untranslated region as potentially the best genome sequence for developing transgenic tobacco.
