Abstract
Long-term tumour recurrence rates and complications of endoscope-assisted partial superficial parotidectomy (PSP) are rarely reported compared to traditional open approaches. This retrospective study included 306 patients with superficial parotid benign neoplasms who were divided into an endoscopy group (endoscope-assisted PSP, n = 102) and a control group (conventional PSP, n = 204). There were no significant differences in clinical and pathological characteristics between the two groups, except age (P = 0.001). Three patients had confirmed recurrence during a mean follow-up duration of 125.1 months. Ten (9.8%) patients in the endoscopy group and 22 (10.8%) in the control group developed transient facial nerve palsy (P = 0.792), and recovered 6 months after the operation. Nine (8.8%) and 19 (9.3%) patients, respectively, suffered from Frey syndrome (P = 0.889). A sensory deficit of the auricle occurred in 24 (23.5%) and 57 (27.9%) patients respectively (P = 0.410). Patients in the endoscopy group were more satisfied with the postoperative scar than those in the control group (P < 0.001). This study demonstrated that the endoscope-assisted PSP can be curative, with better cosmetic outcomes than the conventional approach, and does not increase the incidence of postoperative complications or the local recurrence rate.

Abstract
Objective: To explore the association between sleep duration and the risk of frailty among the elderly over 80 years old in China. Methods: Using the data from five surveys of the China Elderly Health Influencing Factors Follow-up Survey (CLHLS) (2005, 2008-2009, 2011-2012, 2014, and 2017-2018), 7 024 elderly people aged 80 years and above were selected as the study subjects. Questionnaires and physical examinations were used to collect information on sleep time, general demographic characteristics, functional status, physical signs, and illness. The frailty state was evaluated based on a frailty index that included 39 variables. The Cox proportional risk regression model was used to analyze the correlation between sleep time and the risk of frailty occurrence. A restricted cubic spline function was used to analyze the dose-response relationship between sleep time and the risk of frailty occurrence. The likelihood ratio test was used to analyze the interaction between age, gender, sleep quality, cognitive impairment, and sleep duration. Results: The age M (Q1, Q3) of 7 024 subjects was 87 (82, 92) years old, with a total of 3 435 (48.9%) patients experiencing frailty. The results of restricted cubic spline function analysis showed that there was an approximate U-shaped relationship between sleep time and the risk of frailty. When sleep time was 6.5-8.5 hours, the elderly had the lowest risk of frailty; Multivariate Cox proportional risk regression model analysis showed that compared to 6.5-8.5 hours of sleep, long sleep duration (>8.5 hours) increased the risk of frailty by 13% (HR: 1.13; 95%CI: 1.04-1.22). Conclusion: There is a nonlinear association between sleep time and the risk of frailty in the elderly.

Abstract
OBJECTIVE To investigate the auditory response patterns of mouse primary auditory cortex (A1) neurons. METHODS In vivo cell-attached recordings and neural network modeling were performed to detect the changes in response patterns of A1 neurons of awake C57BL/6J mice to sound stimulation with varying lengths. A1 neuron signals were recorded for 216 neurons in 20 awake mice using a target sound stimulation sequence, and the classification and response characteristics of A1 neuron response patterns were examined using post-stimulus spike time histograms. To simulate the diversity of the A1 neuron response patterns, an A1 neuron model was established based on the Wilson-Cowan model and integral-firing model. The neuron connection weight parameters in the model were calculated by examining the micro loop structure of the pyramidal neurons, parvalbumin neurons, and somatostatin neurons in the A1 region, and the A1 neural network information coding model was constructed. RESULTS The Onset response neurons only had fast spike response within 10 to 40 ms after the beginning of noise stimulation (122 neurons). The Sustained response neurons had spike response continuously during the noise stimulation (26 neurons). The On-off response neurons had fast spike response after the beginning and the end of noise stimulation (40 neurons). The Offset response neurons only had fast spike response within 10 to 40 ms after the end of noise stimulation (22 neurons). In the neural network model, the Onset peak neural activities of A1 pyramidal neurons, parvalbumin neurons, and somatostatin neurons were 0.7483, 0.5236 and 0.9427, respectively, and their response half peak widths were 18.5 ms, 12 ms and 31 ms during the 100 ms noise stimulation, respectively. By changing the feedforward excitation and synaptic inhibition time constants in the model, the neurons generated numerous different types of spike train. CONCLUSION The auditory response of mouse A1 neurons to sound stimuli shows mainly the Onset, Sustained, On-off, and Offset response patterns.

Abstract
Although mouse models of CRC treatments have demonstrated robust immune activation, it remains unclear to what extent CRC patients' APCs and TILs interact to fuel or quench treatment-induced immune responses. Our ex vivo characterization of tumor and adjacent colon cell suspensions suggest that contrasting environments in these tissues promoted inversed expression of T cell co-stimulatory CD80, and co-inhibitory programmed death (PD)-ligand1 (PD-L1) on intratumoral vs. colonic APCs. While putative tumor-specific CD103+CD39+CD8+ TILs expressed lower CD69 (early activation marker) and higher PD-1 (extended activation/exhaustion marker) than colonic counterparts, the latter had instead higher CD69 and lower PD-1 levels. Functional comparisons showed that intratumoral APCs were inferior to colonic APCs regarding protein uptake and upregulation of CD80 and PD-L1 after protein degradation. Our attempt to model CRC treatment-induced T cell activation in vitro showed less interferon (IFN)-γ production by TILs than colonic T cells. In this model, we also measured APCs' CD80 and PD-L1 expression in response to activated co-residing T cells. These markers were comparable in the two tissues, despite higher IFN- γ exposure for colonic APCs. Thus, APCs within distinct intratumoral and colonic milieus showed different activation and functional status, but were similarly responsive to signals from induced T cell activation.

Abstract
In 2019, the rate of primary tooth caries rate among 1 598 preschool children in Shinan District and Shibei District of Qingdao was 59.4%. The multivariate logistic regression model showed that compared with children ≤ 2 years old with history of iron deficiency anemia (IDA), suffering IDA, breastfeeding to 2 years old and no tooth melanin, children ≤ 2 years old without history of IDA, not suffering IDA, breastfeeding to less than 2 years old and heavy tooth melanin had a lower risk of primary tooth caries, with OR (95%CI) values about 0.328 (0.197-0.549), 0.354 (0.208-0.603), 0.636 (0.437-0.926) and 0.301 (0.143-0.635), respectively.

Abstract
BACKGROUND The combination of conventional transarterial chemoembolization (cTACE) and systemic therapy has the potential to treat chemotherapy-refractory unresectable colorectal liver metastases (CRLMs). This study aimed to compare survival after this combined treatment versus systemic chemotherapy alone. METHODS This single-centre RCT included patients with unresectable CRLMs that progressed after first-line treatment. Patients were randomized on a 1 : 1 basis to either systemic chemotherapy with or without cTACE, without further stratification. The primary outcome was progression-free survival (PFS). Secondary outcomes were overall response rate, disease control rate, conversion rate to liver resection, overall survival, and adverse events. RESULTS Of 180 patients recruited, 168 were randomized. Eighty-five patients in arm A received systemic chemotherapy plus cTACE and 83 in arm B received systemic chemotherapy alone. Median PFS was longer in arm A than B (6.7 versus 3.8 months; hazard ratio (HR) 0.67, 95 per cent c.i. 0.49 to 0.91; P = 0.009), but did not translate into prolonged median overall survival (18.4 versus 14.8 months; HR = 0.92, 0.62 to 1.36; P = 0.669). Overall response rates (20 versus 22 per cent; P = 0.788) and conversion rate to liver resection (18 versus 16 per cent; P = 0.730) were no different between arms A and B. The disease control rate was higher in arm A than arm B (67 versus 51 per cent; P = 0.030). No adverse event higher than grade 3 according to the Common Terminology Criteria for Adverse Events was observed during treatment. CONCLUSION Systemic chemotherapy plus cTACE is a safe option as second-line treatment for unresectable colorectal liver metastases, with a modest effect on PFS.

Abstract
e14510 Background: CD4 is highly and uniformly expressed T-cell lymphomas (TCL) including PTCL and CTCL, suggesting its potential as a surface target for CAR-T therapy. However, there is a significant risk of potential antigen masking by CAR introduced into tumor cells, which thereby leads to escape of tumor cells from recognition by CAR-T cells. For example, Ruella M et al ( Nat Med, 2018) reported that contaminating malignant B cells transduced with anti-CD19 CAR (called CAR-B cells) in the manufacturing process led to the CD19 antigen masking by CAR molecules. Hence, CAR-B tumor cells could not be recognized by CAR-T cells, which resulted in relapse of CAR expressing B lymphoma cells. A similar antigen masking effect might occur for the anti-CD4 CAR-T product. Methods: To identify single-chain variable fragment (scFv) without antigen-masking effect, large panels of fully human monoclonal antibodies were converted to format of CAR modality with the scFv-4-1BB-CD3z structure and introduced into CD4+ and CD8+ T cells. After lentiviral transduction, residual CD4+ T cells were quantified and the CARs with complete elimination of CD4+ T cells were selected for further validation. The selected CAR constructs were then introduced into CD4+ TCL cells HH (CAR-HH cells) to mimic the potential risk of introducing CAR into contaminating malignant T cells in the manufacturing process. Thereafter, CAR-HH cells were subject to in vitro killing assay by LB1901. Last, identified CAR constructs were further tested for in vitro and in vivo anti-tumor efficacy and off-target binding and killing. Results: Introduction of LB1901 CAR into CD4+ and CD8+ T cells led to complete elimination of CD4+ T cells, suggesting no masking effect of CAR on CD4 antigen. Furthermore, the introduction of CAR into CD4+ HH cells did not protect HH cells from being recognized and eliminated by LB1901, further confirming that the CAR modality of LB1901 does not mask CD4 antigen. An in vivo anti-tumor efficacy study showed that LB1901 exhibited dose-dependent anti-tumor activity without significant adverse effect. As low as 0.3 million CAR+ cells completely suppressed tumor growth, suggesting the potent anti-tumor activity by LB1901. Immunohistochemical analysis of normal tissues with LB1901 scFV binder showed no off-target binding. Furthermore, no killing toward CD4- cell lines and primary cells derived from vital organs or antigen-independent cytokine release was observed in vitro. Conclusions: Altogether, the in vitro and in vivo studies showed that LB1901 did not mask the CD4 antigen but exhibited potent anti-tumor activity without off-target effects. A phase 1 study of LB1901 CAR-T in patients with relapsed or refractory PTCL or CTCL is ongoing in the US to assess the safety and tolerability of LB1901 CAR-T (NCT04712864).

Abstract
Simple Summary Colorectal cancer (CRC) remains the third most common malignancy. Tumor-infiltrating lymphocytes (TILs) have emerged as correlates to CRC patient outcome after treatment. The pro- or anti-tumor responses of TILs are usually assessed in cell suspensions of fresh tumors that were surgically removed a few hours earlier. We propose a platform for concurrent enumeration and in vitro functional evaluation of TILs in cryopreserved tumor biopsies, offering the benefit of postponing tumor processing and analyses of TILs in cell suspensions until clinical post-treatment responses are established. Our platform is practical considering the inconsistent time when patient samples become available for research purposes and can be readily utilized by other laboratories. With a fresh portion of tumor biopsies as benchmark, we validated the recovery of viable TILs capable of interferon (IFN)-γ responses in the cryopreserved portion of same biopsies. Ultimately, this platform could provide sufficient information on TILs, to also predict patient outcome after CRC treatments. Abstract TILs comprise functionally distinct conventional and unconventional T cell subsets and their role in responses to CRC treatments is poorly understood. We explored recovery of viable TILs from cryopreserved tumor biopsies of (chemo)-radiated patients with rectal cancer to establish a platform for retrospective TIL analyses of frozen tumors from pre-selected study cohorts. Frequencies of TIL subsets and their capacity to mount IFN-γ responses in cell suspensions of fresh vs. cryopreserved portions of the same tumor biopsies were determined for platform validation. The percentages and proportions of CD4+ TILs and CD8+ cytotoxic T lymphocytes (CTLs) among total TILs were not affected by cryopreservation. While recovery of unconventional γδ T cells and mucosal-associated invariant T cells (MAIT cells) was stable after cryopreservation, the regulatory T cells (Tregs) were reduced, but in sufficient yields for quantification. IFN-γ production by in vitro-stimulated CD4+ TILs, CTLs, γδ T cells, and MAIT cells were proportionally similar in fresh and cryopreserved tumor portions, albeit the latter displayed lower levels. Thus, the proposed platform intended for TIL analyses on cryopreserved tumor biobank biopsies holds promises for studies linking the quantity and quality of TIL subsets with specific clinical outcome after CRC treatment.

Abstract
Although intramuscular (i.m.) administration is the most commonly used route for licensed vaccines, subcutaneous (s.c.) delivery is being explored for several new vaccines under development. Here, we use rhesus macaques, physiologically relevant to humans, to identify the anatomical compartments and early immune processes engaged in the response to immunization via the two routes. Administration of fluorescently labeled HIV-1 envelope glycoprotein trimers displayed on liposomes enables visualization of targeted cells and tissues. Both s.c. and i.m. routes induce efficient immune cell infiltration, activation, and antigen uptake, functions that are tightly restricted to the skin and muscle, respectively. Antigen is also transported to different lymph nodes depending on route. However, these early differences do not translate into significant differences in the magnitude or quality of antigen-specific cellular and humoral responses over time. Thus, although some distinct immunological differences are noted, the choice of route may instead be motivated by clinical practicality.

Abstract
Curcumin (Cur) has been used extensively in dietary supplement with antioxidant and anti-apoptotic properties. Although dibutyl phthalate (DBP) has adverse effects on the kidney, any association between DBP exposure and the role of Cur is unclear. We tested the hypothesis that exposure to DBP has adverse consequences on renal dysfunction in mice and the potential protective role of Cur in decreasing DBP-induced renal dysfunction via inhibiting oxidative stress and apoptosis. Kidney function, oxidative stress biomarkers, and apoptosis factors as well as Bcl-2 and Bax were investigated. The results showed a marked increase of renal dysfunction, oxidative stress and apoptosis level after DBP exposure compared to the control. While administration of Cur to DBP-treated mice may reduce these adverse biochemical changes compared with DBP-alone group. Overall, these results suggest that oxidative stress and apoptosis are involved in DBP-induced renal disorder, whereas Cur plays a protective role in inhibiting these two pathways.

Abstract
Abstract In cases on compensation for personal injury, the issue of medical expense compensation involves the vital interests of the compensation obligor, the injured party and the medical institution. The rationality of medical expenses is likely to be controversial, however, there is no unified standard and stipulation for the medical expense rationality identification in forensic clinical identification at present, therefore, in the practice of judicial expertise, expert opinions easily become confused, and the legitimate rights of the parties could be infringed, which affects the impartiality and authority of judicial expertise. This article starts with the concept of medical expense and the rationality of medical expense and the reasons for disputes over the rationality of medical expense, to put forward the basic principles that should be followed in the identification of rationality of medical expenses, for peer reference.

Abstract
BACKGROUNDThe live attenuated BPZE1 vaccine candidate induces protection against B. pertussis and prevents nasal colonization in animal models. Here we report on the responses in humans receiving a single intranasal administration of BPZE1.METHODSWe performed multiple assays to dissect the immune responses induced in humans (n = 12) receiving BPZE1, with particular emphasis on the magnitude and characteristics of the antibody responses. Such responses were benchmarked to adolescents (n = 12) receiving the complete vaccination program of the currently used acellular pertussis vaccine (aPV). Using immunoproteomics analysis, potentially novel immunogenic B. pertussis antigens were identified.RESULTSAll BPZE1 vaccinees showed robust B. pertussis-specific antibody responses with regard to significant increase in 1 or more of the following parameters: IgG, IgA, and memory B cells to B. pertussis antigens. BPZE1-specific T cells showed a Th1 phenotype, and the IgG exclusively consisted of IgG1 and IgG3. In contrast, all aPV vaccines showed a Th2-biased response. Immunoproteomics profiling revealed that BPZE1 elicited broader and different antibody specificities to B. pertussis antigens as compared with the aPV that primarily induced antibodies to the vaccine antigens. Moreover, BPZE1 was superior at inducing opsonizing antibodies that stimulated ROS production in neutrophils and enhanced bactericidal function, which was in line with the finding that antibodies against adenylate cyclase toxin were only elicited by BPZE1.CONCLUSIONThe breadth of the antibodies, the Th1-type cellular response, and killing mechanisms elicited by BPZE1 may hold prospects of improving vaccine efficacy and protection against B. pertussis transmission.TRIAL REGISTRATIONClinicalTrials.gov NCT02453048, NCT00870350.FUNDINGILiAD Biotechnologies, Swedish Research Council (Vetenskapsrådet), Swedish Heart-Lung Foundation.

Abstract
BACKGROUND Herpes zoster ophthalmicus occurs primarily in elderly or immunocompromised individuals after reactivation of varicella zoster virus (VZV). Recurrences of zoster ophthalmicus are uncommon because the reactivation efficiently boosts anti-VZV immunity. A 28-year-old female presented to our clinic with a history of multiple recurrences of zoster ophthalmicus. METHODS Whole-exome sequencing (WES), analyses of VZV T-cell immunity, and pathogen recognition receptor function in primary antigen-presenting cells (APCs) and fibroblasts were performed. RESULTS Normal VZV-specific T-cell immunity and antibody response were detected. Whole-exome sequencing identified a heterozygous nonsynonymous variant (c.2324C > T) in the Toll-like receptor 3 (TLR3) gene resulting in formation of a premature stop-codon. This alteration could potentially undermine TLR3 signaling in a dominant-negative fashion. Therefore, we investigated TLR3 signaling responses in APCs and fibroblasts from the patient. The APCs responded efficiently to stimulation with TLR3 ligands, whereas the responses from the fibroblasts were compromised. CONCLUSIONS We report a novel TLR3 variant associated with recurrent zoster ophthalmicus. Toll-like receptor 3 responses that were unaffected in APCs but diminished in fibroblasts are in line with previous reports linking TLR3 deficiency with herpes simplex virus encephalitis. Mechanisms involving compromised viral sensing in infected cells may thus be central to the described immunodeficiency.

Abstract
OBJECTIVES To assess the effects of electroacupuncture (EA) at the Zusanli (ST36), Guanyuan (CV4), Zhongwan (CV12), and Fenglong (ST40) acupoints on sirtuin 1 (SIRT1) and glucose transporter type 4 (GLUT4) expression in high-fat diet (HFD)-induced insulin-resistant (IR) rats. METHODS Wistar rats were divided into normal control (NC), HFD, and HFD+EA groups. NC rats were fed a standard chow diet and did not receive EA. After being fed an HFD for eight weeks, rats in the HFD+EA group received EA at 2 Hz five times a week for eight weeks. Rats in the HFD group did not receive EA. RESULTS In HFD-induced IR rats, EA inhibited body weight increase and water intake, which were observed in HFD rats. EA had no effect on fasting blood glucose and postprandial blood sugar levels. Intraperitoneal insulin tolerance testing revealed that EA enhanced insulin sensitivity in HFD-induced IR rats. Compared with NC rats, SIRT1 and GLUT4 were downregulated in the quadriceps femoris of HFD-fed rats but were increased after eight weeks of EA stimulation. CONCLUSIONS EA enhanced HFD-induced insulin resistance by activating SIRT1 and GLUT4 in the quadriceps femoris. These results provide powerful evidence supporting the beneficial effects of EA on HFD-induced insulin resistance.

Abstract
OBJECTIVE To investigate the regulatory effect of miR-328 on biological behaviors of hepatocellular carcinoma (HCC) cells, such as invasion and proliferation. PATIENTS AND METHODS The expressions of miR-328 were detected in 48 pairs of HCC tissue samples and matched adjacent tissues, as well as in 3 kinds of HCC cell lines via quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Further, we analyzed the effects of miR-328 inhibition on cell invasion, proliferation, cell apoptosis, and cell cycle. Dual-luciferase activity assay was performed to examine the potential target gene PTEN which was predicted by an online database. Protein levels were detected using Western blot assay. RESULTS The expression of miR-328 was significantly increased in HCC tissue samples. Decreased miR-328 in HCC cells significantly attenuated cell invasion and proliferation capacities, promoted cell apoptosis and induced cell cycle arrest at G0/G1 phase. Moreover, PTEN was verified as a target gene of miR-328 by dual-luciferase activity assay, qRT-PCR and Western blot. Furthermore, the silence of PTEN neutralized the suppressive effect of decreased miR-328 on cell growth and metastasis. CONCLUSIONS MiR-328 is involved in the development of HCC via regulating PTEN, which might provide a new target for HCC diagnosis and therapy.

Abstract
The ALVAC-HIV clade B/AE and equivalent SIV-based/gp120 + Alum vaccines successfully decreased the risk of virus acquisition in humans and macaques. Here, we tested the efficacy of HIV clade B/C ALVAC/gp120 vaccine candidates + MF59 or different doses of Aluminum hydroxide (Alum) against SHIV-Cs of varying neutralization sensitivity in macaques. Low doses of Alum induced higher mucosal V2-specific IgA that increased the risk of Tier 2 SHIV-C acquisition. High Alum dosage, in contrast, elicited serum IgG to V2 that correlated with a decreased risk of Tier 1 SHIV-C acquisition. MF59 induced negligible mucosal antibodies to V2 and an inflammatory profile with blood C-reactive Protein (CRP) levels correlating with neutralizing antibody titers. MF59 decreased the risk of Tier 1 SHIV-C acquisition. The relationship between vaccine efficacy and the neutralization profile of the challenge virus appear to be linked to the different immunological spaces created by MF59 and Alum via CXCL10 and IL-1β, respectively.

Abstract
Background Previous studies have shown that industry funded trials are associated with pro-industry conclusions and publication bias. Less is known about the role of industry funders and their influence on trial conclusions and time to publication. Methods We identified all industry funded RCTs published in six high-impact clinical journals between 2014 and 2016 to estimate the prevalence of the role of industry funders in trial design, data collection, data analyses, data interpretation and manuscript writing. Ordinal logistic regression was used to assess the association between the role of industry funders and trial conclusions, which was classified on a five-point scale. Cox proportional-hazards were used to examine the effect of role of funder on time to publication. Results Of the 255 eligible RCTs, industry funders had a role in trial design in 179 (70.2%) trials, data collection in 160 (62.7%) trials, data analyses in 173 (67.8%) trials, data interpretation in 135 (52.9%) trials and manuscript writing in 168 (65.9%) trials. Trials with any role of industry funders had 3.6 times (95% CI 2.0-6.6) higher odds of having positive conclusions compared with those without role of industry funders. In trials with any role of industry funders, positive trials were published more rapidly than negative trials (hazard ratio = 4.3; 95% CI 2.7-6.7, P < 0.001), while for trials without role of industry funders, there was no association (hazard ratio = 1.07; 95% CI 0.57-1.99, P = 0.84). Conclusion The involvement of industry funders is common in all stages of clinical trials and was associated with more positive conclusions and more rapid publication of RCTs with positive results.

Abstract
Objective: To assess the efficacy and safety of different opportunity of Saccharomyces boulardii (S. Boulardii) Sachets combined with bismuth quadruple therapy for Helicobacter pylori(H. pylori)eradication. Methods: This experiment was a prospective study. A total of 300 H. pylori-infected patients were enrolled and randomized assigned into three groups. Quadruple therapy group received pantoprazole 40 mg+bismuth potassium citrate capsule 220 mg+amoxicillin 1 000 mg+furazolidone 100 mg, bid, oral for 14 days. The simultaneous probiotic group received pantoprazole 40 mg+bismuth potassium citrate capsule 220 mg+amoxicillin 1 000 mg+furazolidone 100 mg+S. Boulardii Sachets 500 mg,bid,oral for 14 days.There after probiotic group:S.Boulardii Sachets was added on the first day after the end of 14 days in the quadruple group, for 500 mg, bid 14 days. The eradication rates and adverse reactions of the three groups were compared. Results: The eradication rates of H.pylori were 89.0%,90.4% and 91.3% in the quadruple therapy group, the simultaneous probiotic group and the there after probiotic group according to Per-protocol(PP) analysis,respectively,with no statistical difference (P=0.870). According to intention-to-treat(ITT)analysis, 81.0%, 85.0% and 84.0%, respectively, the difference was not statistically significant (P=0.732).The overall incidence of adverse reactions and the incidence of diarrhea and nausea in the simultaneous probiotic group, and the there after probiotic group were lower than those in the quadruple group(P<0.05),and the difference was statistically significant.The overall incidence of adverse reactions and diarrhea in the simultaneous probiotic were lower than those in the there after probiotic group (P=0.021, P=0.007), and the difference was statistically significant. Conclusions: S. Boulardii Sachets combined with quadruple therapy at the same time or after eradication treatment can not improve the H.pylori eradication rate,but can reduce the overall incidence of adverse reactions and the incidence of diarrhea and nausea. It is safer to add S. Boulardii Sachets at the same time than after eradication therapy.

Abstract
BACKGROUND AND PURPOSE Some retrospective studies have found that the aneurysm wall enhancement on high-resolution MR vessel wall postgadolinium T1WI has the potential to distinguish unstable aneurysms. This study aimed to identify hemodynamic characteristics that differ between the enhanced and nonenhanced areas of the aneurysm wall on high-resolution MR vessel wall postgadolinium T1WI. MATERIALS AND METHODS TOF-MRA and high-resolution MR vessel wall T1WI of 25 patients were fused to localize the enhanced area of the aneurysm wall. Using computational fluid dynamics, we studied the aneurysm models. Mean static pressure, mean wall shear stress, and oscillatory shear index were compared between the enhanced and nonenhanced areas. RESULTS The aneurysmal enhanced area had lower wall shear stress (P < .05) and a lower oscillatory shear index (P = .021) than the nonenhanced area. In addition, the whole aneurysm had lower wall shear stress (P < .05) and a higher oscillatory shear index (P = .007) than the parent artery. CONCLUSIONS This study suggests that there are hemodynamic differences between the enhanced and nonenhanced areas of the aneurysm wall on high-resolution MR vessel wall postgadolinium T1WI.

Abstract
OBJECTIVE To observe the change of soft and hard tissue in dental immediate implantation and immediate reconstruction in anterior region after loading 3 years. METHODS Patients with single anterior tooth loss in the Department of Second Dental Center, Peking University School and Hospital of Stomatology from October 2008 to October 2012 were enrolled. The gingival papilla height, labial gingival margin level and peri-implant bone level were measured immediately after the permanent restoration and 3 years later. RESULTS In the study, 20 patients were treated by immediate implantation and immediate reconstruction for 22 implants; 24 patients were treated by delayed implant for 29 implants. Implant stability quotient (ISQ) value of the two groups showed no significant difference before permanent restoration (P>0.05). In all the cases after loading 3 years, the average mesial gingival papilla height in implant area of the immediate group and delayed group changed by (0.34±0.54) mm and (0.05±0.39) mm respectively (P=0.07), the distal gingival papilla height changed by (0.43±0.42) mm and (0.36±0.48) mm respectively (P=0.13), while the labial gingival margin level shrinkages were (0.70±0.40) mm and (0.62±0.34) mm respectively (P=0.23). Peri-implant bone losses in the mesial side were (1.02±0.50) mm and (0.88±0.46) mm respectively (P=0.53), while those in the distal side were (1.05±0.34) mm and (0.95±0.47) mm respectively (P=0.21). All these indicators showed no significant difference between the two groups (P>0.05); When the permanent prostheses delivered, the distributions of the gingival papilla index were different between the two groups whether in the mesial side or in the distal side (P<0.05). CONCLUSION The changes of the soft and hard tissue of the immediate implantation and immediate reconstruction in anterior region after loading 3 years were basically equivalent to the conventional implant restoration. But, the former was obviously better than the latter in reducing the duration of treatment and in getting the ideal dental papilla aesthetic effect.

Abstract
Objective: To establish a study cohort of chronic hepatitis B (CHB) in Qidong and evaluate its baseline characteristics. Methods: CHB outpatients of the Third People's Hospital of Qidong were invited to participate in baseline survey from January 1, 2016, including questionnaire survey, liver function detection, serum detection of HBV infection and upper abdomen ultrasound detection. Anticipated sample size was at least one thousand. Baseline data were inputted by EpiData 3.1 software and then cleaned and analyzed by SAS 9.3 software. Results: As of 18 July, 2016, a total of 1 006 participants had been enrolled into the current study, including 615 males with an average age of (44.26±9.97) years and 391 females with an average age of (46.66±11.17) years. The difference in family history of liver disease was not significant between males and females (P>0.05), while the differences in other key information, such as age, education level, tobacco consumption, alcohol drinking, tea consumption, and antiviral intervention, were significant between males and females (P<0.05). Among the key clinical parameters, such as ALT, HBeAg, HBsAg, HBV DNA, albumin, and width of splenic vein and portal vein, only the abnormal rates of ALT and total bilirubin levels were higher in males than in females, the difference was significant (P<0.05). Conclusion: Outpatient department-based CHB cohort was established successfully in Qidong, and sub-cohort could be divided according to the differences on baseline characteristics.

Abstract
The innate immune mechanisms by which adjuvants enhance the potency and protection of vaccine-induced adaptive immunity are largely unknown. We introduce a model to delineate the steps of how adjuvant-driven innate immune activation leads to priming of vaccine responses using rhesus macaques. Fluorescently labeled HIV-1 envelope glycoprotein (Env) was administered together with the conventional aluminum salt (alum) adjuvant. This was compared to Env given with alum with preabsorbed Toll-like receptor 7 (TLR7) ligand (alum-TLR7) or the emulsion MF59 because they show superiority over alum for qualitatively and quantitatively improved vaccine responses. All adjuvants induced rapid and robust immune cell infiltration to the injection site in the muscle. This resulted in substantial uptake of Env by neutrophils, monocytes, and myeloid and plasmacytoid dendritic cells (DCs) and migration exclusively to the vaccine-draining lymph nodes (LNs). Although less proficient than monocytes and DCs, neutrophils were capable of presenting Env to memory CD4+ T cells. MF59 and alum-TLR7 showed more pronounced cell activation and overall higher numbers of Env+ cells compared to alum. This resulted in priming of higher numbers of Env-specific CD4+ T cells in the vaccine-draining LNs, which directly correlated with increased T follicular helper cell differentiation and germinal center formation. Thus, strong innate immune activation promoting efficient vaccine antigen delivery to infiltrating antigen-presenting cells in draining LNs is an important mechanism by which superior adjuvants enhance vaccine responses.

Abstract
OBJECTIVES To investigate hypoxia-inducible factor 1-alpha (HIF-1α) and vascular endothelial growth factor (VEGF) expression under altered loading, and to explore the relationship between loading and hypoxia in the mandibular condylar cartilage of young rats. SETTING AND SAMPLE POPULATION Eighty Sprague-Dawley rats. MATERIAL AND METHODS The reduced loading group was fed soft food, and their incisors were cut to avoid occlusal contact. The increased loading group was fed hard food and had forced jaw-opening. Ten rats from each group (n = 10) were sacrificed at 12, 24, 48, and 96 hours after initiation of the experiment. Pimonidazole hydrochloride (Hypoxyprobe-1, HP-1) was used as a hypoxia marker to confirm the hypoxic state. Hypoxic chondrocytes as indicated by HP-1, HIF-1α and VEGF protein expressions were recognized by immunohistochemical detection. HIF-1α and VEGF mRNA expressions were detected by semi-quantitative RT-PCR. RESULTS Hypoxyprobe-1 was confined in the upper layers of cartilage, and was most strongly expressed in the weight-bearing area of TMJ at 12 and 96 hours. Staining of HIF-1α and VEGF was most strongly expressed in the chondrocytes of the fibrous and proliferative layer at all time points. Furthermore, expressions were also displayed in the hypertrophic and calcified layers at 48 and 96 hours. The expressions of HIF-1α and VEGF mRNA were higher in the increased loading group than in the reduced loading group at 48 and 96 hours (P < . 05). CONCLUSION Mechanical loading seems to directly induce weight-bearing area hypoxia followed by new vessel formation, which indicates that these factors are related and important for the development of cartilage.

Abstract
Myeloid-derived suppressor cells (MDSCs) are major regulators of T cell responses in several pathological conditions. Whether MDSCs increase and influence T cell responses in temporary inflammation, such as after vaccine administration, is unknown. Using the rhesus macaque model, which is critical for late-stage vaccine testing, we demonstrate that monocytic (M)-MDSCs and polymorphonuclear (PMN)-MDSCs can be detected using several of the markers used in humans. However, whereas rhesus M-MDSCs lacked expression of CD33, PMN-MDSCs were identified as CD33+ low-density neutrophils. Importantly, both M-MDSCs and PMN-MDSCs showed suppression of T cell proliferation in vitro. The frequency of circulating MDSCs rapidly and transiently increased 24 h after vaccine administration. M-MDSCs infiltrated the vaccine injection site, but not vaccine-draining lymph nodes. This was accompanied by upregulation of genes relevant to MDSCs such as arginase-1, IDO1, PDL1, and IL-10 at the injection site. MDSCs may therefore play a role in locally maintaining immune balance during vaccine-induced inflammation.

Abstract
Modified mRNA vaccines have developed into an effective and well-tolerated vaccine platform that offers scalable and precise antigen production. Nevertheless, the immunological events leading to strong antibody responses elicited by mRNA vaccines are largely unknown. In this study, we demonstrate that protective levels of antibodies to hemagglutinin were induced after two immunizations of modified non-replicating mRNA encoding influenza H10 encapsulated in lipid nanoparticles (LNP) in non-human primates. While both intradermal (ID) and intramuscular (IM) administration induced protective titers, ID delivery generated this response more rapidly. Circulating H10-specific memory B cells expanded after each immunization, along with a transient appearance of plasmablasts. The memory B cell pool waned over time but remained detectable throughout the 25-week study. Following prime immunization, H10-specific plasma cells were found in the bone marrow and persisted over time. Germinal centers were formed in vaccine-draining lymph nodes along with an increase in circulating H10-specific ICOS+ PD-1+ CXCR3+ T follicular helper cells, a population shown to correlate with high avidity antibody responses after seasonal influenza vaccination in humans. Collectively, this study demonstrates that mRNA/LNP vaccines potently induce an immunological repertoire associated with the generation of high magnitude and quality antibodies.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common functional gastrointestinal disorder. Accumulating evidence suggests the crucial role of central nervous system in the development and maintenance of FD. In particular, periaqueductal gray (PAG) has demonstrated an important role in modulation of pain and emotion, which may be related to FD. However, the study of the PAG in FD is still limited. This study aimed to assess intrinsic connectivity of the PAG in FD patients. METHODS Resting-state functional magnetic imaging (fMRI) data were collected from 66 FD patients and 42 healthy controls (HCs). Functional connectivity analysis was performed to investigate the PAG connectivity pattern differences between the patients and HCs. We then examined the relationships between functional connectivity within the PAG networks and FD symptoms. KEY RESULTS Compared to HCs, patients had increased PAG connectivity with the insula, and decreased PAG connectivity with the orbitofrontal cortex (OFC), dorsolateral prefrontal cortex (dlPFC) and hippocampus/parahippocampus (HIPP/paraHIPP). There were positive correlations between disease duration and PAG connectivity with the putamen and supplementary motor area (SMA), and positive correlations between symptom severity and PAG connectivity with the insula. FD patients with high level of anxiety and depression had altered PAG connectivity with the anterior cingulate cortex (ACC), precuneus, dlPFC and caudate, compared to other patients. CONCLUSIONS & INFERENCES These findings indicate that abnormal intrinsic network of the PAG might be associated with abnormality of pain processing and disruption of emotion processing in FD patients. Our study further complements neuroimaging findings about FD.

Abstract
Series of green laser diodes (LDs) with different (In)GaN barrier layers are investigated. It is found that the optical confinement factor of multi-quantum well (MQW) always increases with increasing indium content of InGaN barrier layer, which results in a decrease of threshold current when indium content of InGaN barrier layer increases from 0 to 5%. However, when a high In content InGaN barrier is used (> 5%), both threshold current and slop efficiency of LDs deteriorate. It may be attributed to the waste of carriers in the potential well at the interface between the last barrier (LB) and the upper waveguide (UWG) layers, which is induced by the piezoelectric polarization effect in high In content InGaN LB layer. Therefore, a new LD structure using a thin thickness of the LB layer to reduce the effect of polarization shows a low threshold current and a high output power even when the In content of barrier layers is as large as 7%.

Abstract
OBJECTIVE Myocarditis is an inflammatory heart muscle disease associated with cardiac dysfunction, and autoimmunity is considered to play an important role in the pathogenesis of myocarditis. CXCL13 and its receptor CXCR5 have been reported to be associated with many diseases including some cancers and inflammatory diseases, but so far there has been no report on CXCR5/CXCL13 expression in myocarditis. MATERIALS AND METHODS With a mouse experimental autoimmune myocarditis (EAM) model, it was found that the mRNA and protein expression of both CXCR5 and CXCL13 were increased in myocardial tissue in the EAM mice. This revealed certain connection between CXCR5/CXCL13 with autoimmune myocarditis, so CXCR5 and CXCL13 may be used as a biomarker for autoimmune myocarditis diagnosis. RESULTS The results also demonstrated increased expression of pro-inflammatory cytokines IL-1β, IL-6, IL-17 and TNF-α in the serum of myocardial tissue in the EAM mice. These pro-inflammatory cytokines may be important targets for developing new drugs in treating myocarditis. CONCLUSIONS The current study established an association between CXCR5/CXCL13, autoimmune myocarditis and pro-inflammatory cytokines, and provided sound basis for further studies on mechanism and treatment of autoimmune myocarditis.

Abstract
The optical power emitting from the cavity facet of blue InGaN-based laser diodes (LDs) is measured to investigate the efficiency droop. The efficiency droop behavior of blue InGaN-based LDs near the threshold is confirmed in our experiments. From measurements of optical power at different wavelengths, it is analyzed that the droop behavior of LDs can be ascribed to the efficiency reduction of longer wavelengths. The efficiency of longer wavelengths is subject to the carrier occupation process in quantum levels. In addition, it is found that the droop behavior may be largely affected by the relatively large threshold current of InGaN-based LDs and the screening effect of polarization, and it can be suppressed by stimulated emission.

Abstract
The aim of this research was to explore whether IL-18 can be a serological marker for the diagnosis of systemic-onset juvenile idiopathic arthritis (sJIA). A total of 23 sJIA patients (13 males, median age 8.2), 20 acute lymphoblastic leukemia (ALL) patients, 18 patients with severe infections (SIF), 26 Kawasaki disease (KD) patients, 18 juvenile idiopathic arthritis (JIA) patients, and 25 healthy control patients were selected for this study. Enzyme-linked immunosorbent assays (ELISAs) were used to determine the serum concentrations of the S100A8, S100A9, and IL-6 proteins. The serum IL-18 levels were detected by a cytometric bead array (CBA). The serum IL-6 concentrations in various disease groups were significantly higher than that in the healthy control group. The IL-6 concentrations exhibited no significant difference between disease groups. The S100A8 level in the sJIA group was significantly higher than those of the ALL, JIA, and healthy control groups but showed no significant difference compared to the SIF and KD groups. The S100A9 serum concentration in the sJIA group was significantly higher than those in the ALL and healthy control groups and exhibited no significant difference from the SIF, KD, and JIA groups. The IL-18 level of the sJIA group was significantly higher than that of the other febrile disease groups. The IL-18 serum concentration may be used as a biological serum marker to distinguish sJIA from other febrile diseases.
