Abstract
Head neck squamous cell carcinoma (HNSCC) is a common kind of malignancies in human body. For HNSCC in early stage, either surgical operation or radiotherapy can acquire satisfactory treatment results. However, any single treatment modality such as surgery alone or single radiation is insufficient to gain satisfactory tumor control. Multidisciplinary treatment (MDT) has become a mainstay and important therapeutic strategy in the management of HNSCC. Among various approaches in the MDT, concurrent chemoradiotheraqpy (CCR) constitutes a major progress, which implicates a lot in improving outcomes and organ preservations in managing HNSCC. In the present review, the history, mechanisms, indications along with side effects and drawbacks, and perspectives of CCR are to be described and discussed, in the hope of providing effective guidance for the domestic MDT, especially CCR in the management of HNSCC.

Abstract
The circadian timing system determines the optimal timing and waveform of drug tolerability, yet treatment itself can alter this system. Gemcitabine is an antimetabolite agent that is active against lung and pancreatic cancers. Tolerability for this drug is best following dosing at ZT 11 in mice. The authors investigated the effects of gemcitabine on the circadian rhythms in body temperature and rest activity as physiological markers of the circadian timing system. Healthy unrestrained B6D2F1 mice implanted with radiotelemetry transmitters were kept in LD 12:12 prior to receiving a single intravenous dose of gemcitabine (200, 400, or 600 mg/kg) at ZT 11 or 23. Gemcitabine (400 mg/kg) transiently suppressed the body temperature rhythm in 50% of the mice dosed at ZT 23, as compared to none of the mice treated at ZT 11 within the 2 days following drug dosing (Fisher 's exact test p = 0.04). The rest-activity circadian rhythm was suppressed in 40% (ZT 11) and 50% (ZT 23) of the mice, respectively. In the mice with persistent circadian rhythms, gemcitabine delivery at ZT 23 resulted in more prominent decreases and slower recovery of circadian mesor and amplitude of both rhythms as compared to mice treated at ZT 11. Gemcitabine also induced a transient internal desynchronization between temperature and activity rhythms following dosing at ZT 23 but not at ZT 11. The delivery of a single therapeutic dose of gemcitabine near its time of least toxicity produced least alterations in circadian physiological outputs, a finding that suggests that the extent of circadian disruption contributes to toxicokinetic processes.

Abstract
Purpose. This study aims to explore the safety and efficacy of a novel treatment-intense pulsed light (IPL) in MGD eyes. Methods. This study is a prospective and open label study. Forty eyes of 40 MGD patients were recruited in the study and received 4 consecutive IPL treatments on day 1, day 15, day 45, and day 75. Ten ocular surface symptoms were evaluated with a subjective face score at every visit. Best spectacle corrected visual acuity, intraocular pressure (IOP), conjunctival injection, upper and lower tear meniscus height (TMH), tear break-up time (TBUT), corneal staining, lid margin and meibomian gland assessments, and meibography were also recorded at every visit, as well as the adverse effects on the eye and ocular surface. Results. Significant improvements were observed in single and total ocular surface symptom scores, TBUT, and conjunctival injection at all the visits after the initial IPL treatment (P < 0.05). Compared to baseline, the signs of eyelid margin, meibomian gland secretion quality, and expressibility were significantly improved at every visit after treatments. There was no regional and systemic threat observed in any patient. Conclusion. Intense pulsed light (IPL) therapy is a safe and efficient treatment in relieving symptoms and signs of MGD eyes.

Abstract
Objective:To explore the molecular mechanism of neural plasticity in the reconstitution following impairment of auditory system,we studied the changing levels of GAP-43 expression in the auditory cortex(AC) in the developing rats and in ototoxicity deafened rats before and after electrical intracochlear stimulation.Method:Auditory brain stem response(ABR) measurements were performed to rats of OAD,NC1,CAD and NC2 group to evaluate hearing function.We studied the changing levels of GAP-43-positive neurons expression in the auditory cortex of the OAD,NC1,EIS1 and EIS2 group and RT-PCR was performed to do semiquantitative analysis.Result:The early electrical intracochlear stimulation elevated GAP-43 level(EIS1,120.00±5.59/HP) in ipsilateral AC instead of in the contralateral AC compared with the non-stimulation group (OAD4W,93.25±4.30/HP),and the two groups had statistical difference(EIS1/OAD4W,129.17%±3.33%,P<0.05).After the late electrical intracochlear stimulation,similar to the early group,the staining level of GAP-43(EIS2,102.50±4.02/HP) in the AC was also higher than the unaffected group(OAD8W,81.67±3.76/HP),and the two groups also had statistical difference(EIS2/OAD8W,123.74%±2.70%,P<0.05).Similarly,the expression of GAP-43 mRNA had the synchronous change with the GAP-43 in the AC.Conclusion:GAP-43 has close correlation with the growth and plasticity of the AC,which can be a significant marker for auditory plasticity.

Abstract
Objective:To research the clinical application of tympanic cavity ventilation tube placement in canal wall down tympanomastoidectomy. Method:There were 52 patients with otitis media received canal wall down tympanomastoidectomy. We placed ventilation tube in posterior hypotympanum during the surgery. After surgery, all patients were followed up in 12 days, 1 month, 2 months, 6 months, and 1 year. The ventilation tubes were withdrew 6 months later, and then the hearing level and tympanic cavity status was evaluated after another half year. Result:All cases were followed up at least 1 year after surgery. Forty-four patients' tubes were removed 6 months later, but other 8 tubes had been extruded within 1 to 3 months. After 1 year, all 52 cases of ears were dry; 39 patients' tympanic membranes were stable, the postoperative complications included tympanic membrane retraction in 7 cases, middle ear effusion in 4 cases, and tympanic membrane perforation at anterior-inferior quadrant in 2 cases; CT examination indicated that 39 patients' aeration between tympanic cavity and Eustachian tube bony portion was normal, 9 patients' tympanic cavity aeration was smaller, and 4 patients' cavity was obstructed; 52 patients' average air conduction thresholds were 12.5 dB lower than that of preoperation. Conclusion:One-stage tympanic cavity ventilation tube placement is a simple, safe and effective method in canal wall down tympanomastoidectomy for middle ear diseases with Eustachian tube severe stenosis or obstruction in bony portion.

Abstract
OBJECTIVE To analyze the (18)F-FDG uptake features and the correlation between (18)F-FDG uptake and the prognosis in patients with pathologic stageⅠlung adenocarcinoma. METHODS One hundred and seventeen patients with stageⅠlung adenocarcinoma proved by surgery, who underwent a preoperative (18)F-FDG PET-CT, were studied retrospectively. The tumors' SUVmax in different groups of clinicopathologic factors were compared. The correlations between the SUVmax and clinicopathologic factors were analyzed using Spearman rank correlation. The ROC was plotted to estimate the most discriminative cut-off point for SUVmax in predicting the recurrence or progression of tumor. The progression-free survival (PFS) in different clinicopathologic groups were estimated using the Kaplan-Meier method and Log-rank test. RESULTS The SUVmax of pathologic stageⅠlung adenocarcinomas were significantly different in different groups of gender, tumor size, density, tumor differentiation grade and T staging, respectively (P<0.05 for all). Patients with a larger tumor size, a higher proportion of solid component, poorer grade of tumor differentiation had a higher SUVmax. The T1b group had a higher SUVmax than T1a and T2a groups. The male group had a higher SUVmax than the female group. The SUVmax was positively correlated with the size of the adenocarcinomas (P<0.01), and was negatively correlated with both the density and tumor differentiation grade (P<0.01). But there was no correlation between SUVmax and the T stage (P>0.05). The patients with an SUVmax of <3.0 had a much better PFS (75.1±3.0 month)than those with an SUVmax of ≥3.0 (52.7±5.9 month)(P<0.01). The tumor with a poorer differentiation grade was associated with reduced PFS (45.7±5.4 months) compared with those with well differentiated tumor (76.7±4.2 month)(P<0.05). The PFS showed no statistically significant differences in different gender, age, smoking history, tumor size, density and T staging groups (P>0.05). CONCLUSIONS (18)F-FDG uptake is correlated with the tumor size, density, and differentiation grade, and has a prognostic value for predicting the PFS in the patients with pathologic stageⅠ lung-adenocarcinoma. Patients with an SUVmax of <3.0 have a much better PFS than those with an SUVmax of ≥3.0.

We report the first measurement of absolute hadronic branching fractions of Λ_{c}^{+} baryon at the Λ_{c}^{+}Λ[over ¯]_{c}^{-} production threshold, in the 30 years since the Λ_{c}^{+} discovery. In total, 12 Cabibbo-favored Λ_{c}^{+} hadronic decay modes are analyzed with a double-tag technique, based on a sample of 567 pb^{-1} of e^{+}e^{-} collisions at sqrt[s]=4.599 GeV recorded with the BESIII detector. A global least-squares fitter is utilized to improve the measured precision. Among the measurements for twelve Λ_{c}^{+} decay modes, the branching fraction for Λ_{c}^{+}→pK^{-}π^{+} is determined to be (5.84±0.27±0.23)%, where the first uncertainty is statistical and the second is systematic. In addition, the measurements of the branching fractions of the other 11 Cabibbo-favored hadronic decay modes are significantly improved.

Abstract
We present a measurement of the azimuthal asymmetries of two charged pions in the inclusive process e^{+}e^{-}→ππX, based on a data set of 62 pb^{-1} at the center-of-mass energy of 3.65 GeV collected with the BESIII detector. These asymmetries can be attributed to the Collins fragmentation function. We observe a nonzero asymmetry, which increases with increasing pion momentum. As our energy scale is close to that of the existing semi-inclusive deep inelastic scattering experimental data, the measured asymmetries are important inputs for the global analysis of extracting the quark transversity distribution inside the nucleon and are valuable to explore the energy evolution of the spin-dependent fragmentation function.

Abstract
In order to understand and imitate the more complex bio-processes and fascinating functions in nature, protein self-assembly has been studied and has attracted more and more interest in recent years. Artificial self-assemblies of proteins have been constructed through many strategies. However, the design of complicated protein self-assemblies utilizing the special profile of building blocks remains a challenge. We herein report linear and 2D nanostructures constructed from a V shape SMAC protein and induced by metal coordination. Zigzag nanowires and wavy 2D nanostructures have been demonstrated by AFM and TEM. The zigzag nanowires can translate to a 2D nanostructure with an excess of metal ions, which reveals the step by step assembly process. Fluorescence and UV/Vis spectra have also been obtained to further study the mechanism and process of self-assembly. Upon the protein nanostructure, fluorescence resonance energy transfer (FRET) could also be detected using fluorescein modified proteins as building blocks. This article provides an approach for designing and controlling self-assembled protein nanostructures with a distinctive topological morphology.

Abstract
This work reports a new method of synthesizing anhydrous lithium sulfide (Li2S) nanocrystals and demonstrates their potential as cathode materials for advanced rechargeable batteries. Li2S is synthesized by reacting hydrogen sulfide (H2S) with lithium naphthalenide (Li-NAP), a thermodynamically spontaneous reaction that proceeds to completion rapidly at ambient temperature and pressure. The process completely removes H2S, a major industrial waste, while cogenerating 1,4-dihydronaphthalene, itself a value-added chemical that can be used as liquid fuel. The phase purity, morphology, and homogeneity of the resulting nanopowders were confirmed by X-ray diffraction and scanning electron microscopy. The synthesized Li2S nanoparticles (100 nm) were assembled into cathodes, and their performance was compared to that of cathodes fabricated using commercial Li2S micropowders (1-5 μm). Electrochemical analyses demonstrated that the synthesized Li2S were superior in terms of (dis)charge capacity, cycling stability, output voltage, and voltage efficiency.

Abstract
Neuronal apoptosis is an important event in hypoxia/reoxygenation (H/R)-induced neuronal injury. Senegenin (Sen), the predominant and most active component in Radix Polygalae root extracts, displays anti-apoptotic and anti-oxidative properties. Sen protects against H/R-induced neuronal apoptosis of highly differentiated PC12 cells and primary cortical neurons. Sen has also been investigated as a source of potential therapeutic targets. In this study, a proteomic approach was used to identify Sen-regulated proteins in PC12 cells. We found that Sen protected against H/R-induced neuronal apoptosis by upregulating RhoGDIα protein expression. The regulatory functions of RhoGDIα were investigated by knocking down RhoGDIα expression in PC12 cells using small interfering RNA (siRNA), followed by quantification of apoptosis and then altering the expression levels of apoptosis-related proteins. Our data show that after silencing RhoGDIα, the neuroprotective effects of Sen on H/R-induced PC12 cell apoptosis were absent. Furthermore, RhoGDIα silencing alleviated the Sen-mediated inhibition of the JNK pathway. Therefore, these findings indicated that Sen attenuates H/R-induced neuronal apoptosis by upregulating RhoGDIα expression and inhibiting the JNK pathway. In addition to the mechanism underlying neuroprotective effects of Sen, RhoGDIα was identified as a putative target of Sen based on a primary rat cortical neuron model of H/R-induced injury.

Abstract
A neutral structure in the DD[over ¯]^{*} system around the DD[over ¯]^{*} mass threshold is observed with a statistical significance greater than 10σ in the processes e^{+}e^{-}→D^{+}D^{*-}π^{0}+c.c. and e^{+}e^{-}→D^{0}D[over ¯]^{*0}π^{0}+c.c. at sqrt[s]=4.226 and 4.257 GeV in the BESIII experiment. The structure is denoted as Z_{c}(3885)^{0}. Assuming the presence of a resonance, its pole mass and width are determined to be [3885.7_{-5.7}^{+4.3}(stat)±8.4(syst)] MeV/c^{2} and [35_{-12}^{+11}(stat)±15(syst)] MeV, respectively. The Born cross sections are measured to be σ[e^{+}e^{-}→Z_{c}(3885)^{0}π^{0},Z_{c}(3885)^{0}→DD[over ¯]^{*}]=[77±13(stat)±17(syst)] pb at 4.226 GeV and [47±9(stat)±10(syst)] pb at 4.257 GeV. The ratio of decay rates B[Z_{c}(3885)^{0}→D^{+}D^{*-}+c.c.]/B[Z_{c}(3885)^{0}→D^{0}D[over ¯]^{*0}+c.c.] is determined to be 0.96±0.18(stat)±0.12(syst), consistent with no isospin violation in the process, Z_{c}(3885)^{0}→DD[over ¯]^{*}.

Abstract
We report the first measurement of the absolute branching fraction for Λ_{c}^{+}→Λe^{+}ν_{e}. This measurement is based on 567 pb^{-1} of e^{+}e^{-} annihilation data produced at sqrt[s]=4.599 GeV, which is just above the Λ_{c}^{+}Λ[over ¯]_{c}^{-} threshold. The data were collected with the BESIII detector at the BEPCII storage rings. The branching fraction is determined to be B(Λ_{c}^{+}→Λe^{+}ν_{e})=[3.63±0.38(stat)±0.20(syst)]%, representing a significant improvement in precision over the current indirect determination. As the branching fraction for Λ_{c}^{+}→Λe^{+}ν_{e} is the benchmark for those of other Λ_{c}^{+} semileptonic channels, our result provides a unique test of different theoretical models, which is the most stringent to date.

Abstract
We report a study of the process e^{+}e^{-}→(D^{*}D[over ¯]^{*})^{0}π^{0} using e^{+}e^{-} collision data samples with integrated luminosities of 1092 pb^{-1} at sqrt[s]=4.23 GeV and 826 pb^{-1} at sqrt[s]=4.26 GeV collected with the BESIII detector at the BEPCII storage ring. We observe a new neutral structure near the (D^{*}D[over ¯]^{*})^{0} mass threshold in the π^{0} recoil mass spectrum, which we denote as Z_{c}(4025)^{0}. Assuming a Breit-Wigner line shape, its pole mass and pole width are determined to be (4025.5_{-4.7}^{+2.0}±3.1) MeV/c^{2} and (23.0±6.0±1.0) MeV, respectively. The Born cross sections of e^{+}e^{-}→Z_{c}(4025)^{0}π^{0}→(D^{*}D[over ¯]^{*})^{0}π^{0} are measured to be (61.6±8.2±9.0) pb at sqrt[s]=4.23 GeV and (43.4±8.0±5.4) pb at sqrt[s]=4.26 GeV. The first uncertainties are statistical and the second are systematic.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most common cancers in the world. MicroRNAs play important roles in the progression of CRC. This study aimed to investigate the role of miR-206 and its novel mechanism in the invasion and metastasis of CRC. METHODOLOGY Real-time RT-PCR or Western blotting was used to detect the expressions of miR-206, FMNL2 and c-MET in CRC cell lines and tissues. Luciferase reporter assays were conducted to detect the associations between miR-206 and 3'UTRs of FMNL2 and c-MET. A series of loss-of-function and gain-of-function assays were performed to evaluate the effect of miR-206 on the proliferation, invasion and metastasis of CRC cells. RESULTS miR-206 was significantly down-regulated in CRC tissues and correlated closely with differentiation, lymphatic metastasis and serosal invasion. miR-206 suppressed CRC cell proliferation by arresting CRC cells in the G1/G0 phase and accelerating apoptosis. miR-206 also inhibited cell invasion and lung metastasis in CRC cells. Mechanically, FMNL2 and c-MET were identified as direct targets of miR-206. And FMNL2 rescued the suppression of miR-206 in the proliferation and invasion of CRC cells. CONCLUSIONS This study revealed functional and mechanistic links between miR-206 and oncogene FMNL2 and c-MET in the progression of CRC. miR-206 functioned as a tumor suppressor in the progression of CRC by targeting FMNL2 and c-MET. Restoration of miR-206 expression may represent a promising therapeutic approach for targeting malignant CRC.

Abstract
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Z_{c}(3900)^{0} with a significance of 10.4σ. The mass and width are measured to be 3894.8±2.3±3.2 MeV/c^{2} and 29.6±8.2±8.2 MeV, respectively, where the first error is statistical and the second systematic. The Born cross section for e^{+}e^{-}→π^{0}π^{0}J/ψ and the fraction of it attributable to π^{0}Z_{c}(3900)^{0}→π^{0}π^{0}J/ψ in the range E_{c.m.}=4.19-4.42 GeV are also determined. We interpret this state as the neutral partner of the four-quark candidate Z_{c}(3900)^{±}.

Stability, Pharmacokinetics, Biodistribution and Safety Assessment of Folate-Conjugated Pullulan Acetate Nanoparticles as Cervical Cancer Targeted Drug Carriers.

Abstract
It is recognized that the stability and journey in the body of nanoparticles are important issues for drug formulations. In this study, we prepared folate-conjugated pullulan acetate nanoparticles (FPANs) and epirubicin loaded FPANs (FPA/EPI) using dialysis method. The storage stability of FPANs and FPA/EPI at 4 degrees C could be up to 3 months. Using folate receptor overexpressed Hela cells, dose dependent cellular uptake and receptor-mediated endocytosis of FPA/EPI were confirmed. From the in vivo pharmacokinetics test, compared to free EPI, half-life time (t½) of FPA/EPI was extended 1.57 times and the area under-the-curve (AUC) increased 3.95 times as well. In addition, biodistribution data showed that, EPI concentration in tumor in FPA/EPI group was 2.01 times higher than that in free EPI group after 96 h; The concentration of drug in liver treated by FPA/EPI was 5.7-11.6 times, while in heart, kidney, especially in stomach and intestine were much lower than those in free EPI group from 24 to 96 h. Furthermore, blank FPANs showed no apparent acute toxicity at dose up to 125 mg/kg. All results suggested that FPA/EPI showed a promising potential on treating cervical carcinoma and its metastatic hepatocellular carcinoma in future because of the high stability, less toxicity and tumor targeting.
