Abstract
The Orthopoxvirus genus, especially variola virus (VARV), monkeypox virus (MPXV), remains a significant public health threat worldwide. The development of therapeutic antibodies against orthopoxviruses is largely hampered by the high cost of antibody engineering and manufacturing processes. mRNA-encoded antibodies have emerged as a powerful and universal platform for rapid antibody production. Herein, by using the established lipid nanoparticle (LNP)-encapsulated mRNA platform, we constructed four mRNA combinations that encode monoclonal antibodies with broad neutralization activities against orthopoxviruses. In vivo characterization demonstrated that a single intravenous injection of each LNP-encapsulated mRNA antibody in mice resulted in the rapid production of neutralizing antibodies. More importantly, mRNA antibody treatments showed significant protection from weight loss and mortality in the vaccinia virus (VACV) lethal challenge mouse model, and a unique mRNA antibody cocktail, Mix2a, exhibited superior in vivo protection by targeting both intracellular mature virus (IMV)-form and extracellular enveloped virus (EEV)-form viruses. In summary, our results demonstrate the proof-of-concept production of orthopoxvirus antibodies via the LNP-mRNA platform, highlighting the great potential of tailored mRNA antibody combinations as a universal strategy to combat orthopoxvirus as well as other emerging viruses.

Abstract
We demonstrate high-harmonic generation for the time-domain observation of the electric field (HHG-TOE) and use it to measure the waveform of ultrashort mid-infrared (MIR) laser pulses interacting with ZnO thin-films or WS2 monolayers. The working principle relies on perturbing HHG in solids with a weak replica of the pump pulse. We measure the duration of few-cycle pulses at 3200 nm, in reasonable agreement with the results of established pulse characterization techniques. Our method provides a straightforward approach to accurately characterize femtosecond laser pulses used for HHG experiments right at the point of interaction.

Abstract
Chikungunya fever (CHIKF) has spread to more than 100 countries worldwide, with frequent outbreaks in Europe and the Americas in recent years. Despite the relatively low lethality of infection, patients can suffer from long-term sequelae. Until now, no available vaccines have been approved for use; however, increasing attention is being paid to the development of vaccines against chikungunya virus (CHIKV), and the World Health Organization has included vaccine development in the initial blueprint deliverables. Here, we developed an mRNA vaccine using the nucleotide sequence encoding structural proteins of CHIKV. And immunogenicity was evaluated by neutralization assay, Enzyme-linked immunospot assay and Intracellular cytokine staining. The results showed that the encoded proteins elicited high levels of neutralizing antibody titers and T cell-mediated cellular immune responses in mice. Moreover, compared with the wild-type vaccine, the codon-optimized vaccine elicited robust CD8+ T-cell responses and mild neutralizing antibody titers. In addition, higher levels of neutralizing antibody titers and T-cell immune responses were obtained using a homologous booster mRNA vaccine regimen of three different homologous or heterologous booster immunization strategies. Thus, this study provides assessment data to develop vaccine candidates and explore the effectiveness of the prime-boost approach.

Abstract
Sea fish contain omega-3 polyunsaturated fatty acids (omega-3 PUFAs) which have been found to reduce triglyceride (TG) levels. However, sea fish may contain pollutants such as mercury which cause oxidative stress and increase TG levels. Therefore, the relationship between sea fish and TG remains unclear. We aimed to explore whether blood mercury (BHg) can affect the effect of sea fish consumption frequency on TG level among Chinese adults. A total of 10,780 participants were included in this study. BHg levels were measured using inductively coupled plasma mass spectrometry (ICP-MS). The associations of sea fish consumption frequency with BHg and TG levels as well as the association of BHg with TG levels were evaluated using multiple linear regression. Causal mediation analysis was used to evaluate the mediation effect of BHg levels on the association of sea fish consumption frequency with TG levels. The frequency of sea fish consumption showed a negative association with TG level. Compared with the participants who never ate sea fish, the TG level decreased by 0.193 mmol/L in those who ate sea fish once a week or more [β (95%CI): -0.193 (-0.370, -0.015)]. Significant positive associations were observed of BHg with TG levels. With one unit increase of log2-transformed BHg, the change of TG level was 0.030 mmol/L [0.030 (0.009, 0.051)]. The association between sea fish consumption and TG was mediated by log2-transformed BHg [total effect = -0.037 (-0.074, -0.001); indirect effect = 0.009 (0.004, 0.015)], and the proportion mediated by log2-transformed BHg was 24.25%. BHg may reduce the beneficial effect of sea fish consumption frequency on TG levels among Chinese adults. Overall, sea fish consumption has more benefits than harms to TG.

Abstract
As the world continues to experience the COVID-19 pandemic, seasonal influenza remain a cause of severe morbidity and mortality globally. Worse yet, coinfection with SARS-CoV-2 and influenza A virus (IAV) leads to more severe clinical outcomes. The development of a combined vaccine against both COVID-19 and influenza is thus of high priority. Based on our established lipid nanoparticle (LNP)-encapsulated mRNA vaccine platform, we developed and characterized a novel mRNA vaccine encoding the HA antigen of influenza A (H1N1) virus, termed ARIAV. Then, ARIAV was combined with our COVID-19 mRNA vaccine ARCoV, which encodes the receptor-binding domain (RBD) of the SARS-CoV-2 S protein, to formulate the final combined vaccine, AR-CoV/IAV. Further characterization demonstrated that immunization with two doses of AR-CoV/IAV elicited robust protective antibodies as well as antigen-specific cellular immune responses against SARS-CoV-2 and IAV. More importantly, AR-CoV/IAV immunization protected mice from coinfection with IAV and the SARS-CoV-2 Alpha and Delta variants. Our results highlight the potential of the LNP-mRNA vaccine platform in preventing COVID-19 and influenza, as well as other respiratory diseases.

Abstract
We aimed to explore the effects of mixtures of lead and various metals on blood pressure (BP) and the odds of pre-hypertension (systolic blood pressure (SBP) 120-139 mmHg, and/or diastolic blood pressure (DBP) 80-89 mmHg) and hypertension (SBP/DBP ≥140/90 mmHg) among Chinese adults in a cross-sectional study. This study included 11,037 adults aged 18 years or older from the 2017-2018 China National Human Biomonitoring. Average BP and 13 metals (lead, antimony, arsenic, cadmium, mercury, thallium, chromium, cobalt, molybdenum, manganese, nickel, selenium, and tin) in blood and urine were measured and lifestyle and demographic data were collected. Weighted multiple linear regressions were used to estimate associations of metals with BP in both single and multiple metal models. Weighted quantile sum (WQS) regression was performed to assess the relationship between metal mixture levels and BP. In the single metal model, after adjusting for potential confounding factors, the blood lead levels in the highest quartile were associated with the greater odds of both pre-hypertension (odds ratio (OR): 1.56, 95% CI: 1.22-1.99) and hypertension (OR:1.75, 95% CI: 1.28-2.40) when compared with the lowest quartile. We also found that blood arsenic levels were associated with increased odds of pre-hypertension (OR:1.31, 95% CI:1.00-1.74), while urinary molybdenum levels were associated with lower odds of hypertension (OR:0.68, 95% CI:0.50-0.93). No significant associations were found for the other 10 metals. WQS regression analysis showed that metal mixture levels in blood were significantly associated with higher SBP (β = 1.56, P < 0.05) and DBP (β = 1.56, P < 0.05), with the largest contributor being lead (49.9% and 66.8%, respectively). The finding suggests that exposure to mixtures of metals as measured in blood were positively associated with BP, and that lead exposure may play a critical role in hypertension development.

Abstract
BACKGROUND Safe and effective vaccines are urgently needed to end the COVID-19 pandemic caused by SARS-CoV-2 infection. We aimed to assess the preliminary safety, tolerability, and immunogenicity of an mRNA vaccine ARCoV, which encodes the SARS-CoV-2 spike protein receptor-binding domain (RBD). METHODS This single centre, double-blind, randomised, placebo-controlled, dose-escalation, phase 1 trial of ARCoV was conducted at Shulan (Hangzhou) hospital in Hangzhou, Zhejiang province, China. Healthy adults aged 18-59 years negative for SARS-CoV-2 infection were enrolled and randomly assigned using block randomisation to receive an intramuscular injection of vaccine or placebo. Vaccine doses were 5 μg, 10 μg, 15 μg, 20 μg, and 25 μg. The first six participants in each block were sentinels and along with the remaining 18 participants, were randomly assigned to groups (5:1). In block 1 sentinels were given the lowest vaccine dose and after a 4-day observation with confirmed safety analyses, the remaining 18 participants in the same dose group proceeded and sentinels in block 2 were given their first administration on a two-dose schedule, 28 days apart. All participants, investigators, and staff doing laboratory analyses were masked to treatment allocation. Humoral responses were assessed by measuring anti-SARS-CoV-2 RBD IgG using a standardised ELISA and neutralising antibodies using pseudovirus-based and live SARS-CoV-2 neutralisation assays. SARS-CoV-2 RBD-specific T-cell responses, including IFN-γ and IL-2 production, were assessed using an enzyme-linked immunospot (ELISpot) assay. The primary outcome for safety was incidence of adverse events or adverse reactions within 60 min, and at days 7, 14, and 28 after each vaccine dose. The secondary safety outcome was abnormal changes detected by laboratory tests at days 1, 4, 7, and 28 after each vaccine dose. For immunogenicity, the secondary outcome was humoral immune responses: titres of neutralising antibodies to live SARS-CoV-2, neutralising antibodies to pseudovirus, and RBD-specific IgG at baseline and 28 days after first vaccination and at days 7, 15, and 28 after second vaccination. The exploratory outcome was SARS-CoV-2-specific T-cell responses at 7 days after the first vaccination and at days 7 and 15 after the second vaccination. This trial is registered with www.chictr.org.cn (ChiCTR2000039212). FINDINGS Between Oct 30 and Dec 2, 2020, 230 individuals were screened and 120 eligible participants were randomly assigned to receive five-dose levels of ARCoV or a placebo (20 per group). All participants received the first vaccination and 118 received the second dose. No serious adverse events were reported within 56 days after vaccination and the majority of adverse events were mild or moderate. Fever was the most common systemic adverse reaction (one [5%] of 20 in the 5 μg group, 13 [65%] of 20 in the 10 μg group, 17 [85%] of 20 in the 15 μg group, 19 [95%] of 20 in the 20 μg group, 16 [100%] of 16 in the 25 μg group; p<0·0001). The incidence of grade 3 systemic adverse events were none (0%) of 20 in the 5 μg group, three (15%) of 20 in the 10 μg group, six (30%) of 20 in the 15 μg group, seven (35%) of 20 in the 20 μg group, five (31%) of 16 in the 25 μg group, and none (0%) of 20 in the placebo group (p=0·0013). As expected, the majority of fever resolved in the first 2 days after vaccination for all groups. The incidence of solicited systemic adverse events was similar after administration of ARCoV as a first or second vaccination. Humoral immune responses including anti-RBD IgG and neutralising antibodies increased significantly 7 days after the second dose and peaked between 14 and 28 days thereafter. Specific T-cell response peaked between 7 and 14 days after full vaccination. 15 μg induced the highest titre of neutralising antibodies, which was about twofold more than the antibody titre of convalescent patients with COVID-19. INTERPRETATION ARCoV was safe and well tolerated at all five doses. The acceptable safety profile, together with the induction of strong humoral and cellular immune responses, support further clinical testing of ARCoV at a large scale.

Abstract
Monoclonal antibodies represent important weapons in our arsenal to against the COVID-19 pandemic. However, this potential is severely limited by the time-consuming process of developing effective antibodies and the relative high cost of manufacturing. Herein, we present a rapid and cost-effective lipid nanoparticle (LNP) encapsulated-mRNA platform for in vivo delivery of SARS-CoV-2 neutralization antibodies. Two mRNAs encoding the light and heavy chains of a potent SARS-CoV-2 neutralizing antibody HB27, which is currently being evaluated in clinical trials, were encapsulated into clinical grade LNP formulations (named as mRNA-HB27-LNP). In vivo characterization demonstrated that intravenous administration of mRNA-HB27-LNP in mice resulted in a longer circulating half-life compared with the original HB27 antibody in protein format. More importantly, a single prophylactic administration of mRNA-HB27-LNP provided protection against SARS-CoV-2 challenge in mice at 1, 7 and even 63 days post administration. In a close contact transmission model, prophylactic administration of mRNA-HB27-LNP prevented SARS-CoV-2 infection between hamsters in a dose-dependent manner. Overall, our results demonstrate a superior long-term protection against SARS-CoV-2 conferred by a single administration of this unique mRNA antibody, highlighting the potential of this universal platform for antibody-based disease prevention and therapy against COVID-19 as well as a variety of other infectious diseases.

Abstract
From June 11, 2020, a surge in new cases of coronavirus disease 2019 (COVID-19) in the largest wholesale market of Beijing, the Xinfadi Market, leading to a second wave of COVID-19 in Beijing, China. Understanding the transmission modes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the personal behaviors and environmental factors contributing to viral transmission is of utmost important to curb COVID-19 rise. However, currently these are largely unknown in food markets. To this end, we completed field investigations and on-site simulations in areas with relatively high infection rates of COVID-19 at Xinfadi Market. We found that if goods were tainted or personnel in market was infected, normal transaction behaviors between sellers and customers, daily physiological activities, and marketing activities could lead to viral contamination and spread to the surroundings via fomite, droplet or aerosol routes. Environmental factors such as low temperature and high humidity, poor ventilation, and insufficient hygiene facilities and disinfection practices may contribute to viral transmission in Xinfadi Market. In addition, precautionary control strategies were also proposed to effectively reduce the clustering cases of COVID-19 in large-scale wholesale markets.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic increased the burden on many healthcare systems and in the process, exposed the need for medical resources and physical space. While few studies discussed the efficient utilization of medical resources and physical space so far. Therefore, this study aimed to summarize experiences related to facilities used for centralized isolation for medical observation and treatment during the COVID-19 pandemic in China and to provide suggestions to further improve the management of confirmed cases, suspected cases, and close contacts. In China, three types of facilities for centralized isolation (Fangcang shelter hospitals, refitted non-designated hospitals, and quarantine hotels) underwent retrofitting for the treatment and isolation of confirmed and suspected cases. These facilities mitigated the immediate high demand for space. Moreover, in order to minimize infection risks in these facilities, regulators and governmental agencies implemented new designs, management measures, and precautionary measures to minimize infection risk. Other countries and regions could refer to China's experience in optimally allocating social resources in response to the COVID-19 pandemic. As a conclusion, government should allocate social resources and construct centralized isolation and quarantine facilities for an emergency response, health authorities should issue regulations for centralized isolation facilities and pay strict attention to the daily management of these facilities, a multidisciplinary administration team is required to support the daily operation of a centralized isolation facility, in-depth studies and international collaboration on the centralized isolation policy are encouraged.

Abstract
OBJECTIVE Globally, developed countries such as the United States, Canada, Germany, Korea, have carried out long-term and systematic biomonitoring programs for environmental chemicals in their populations. The China National Human Biomonitoring (CNHBM) was to document the extent of human exposure to a wide array of environmental chemicals, to understand exposure profiles, magnitude and ongoing trends in exposure in the general Chinese population, and to establish a national biorepository. METHODS CNHBM adopted three-stage sampling method to obtain a nationally representative sample of the population. A total of 21,888 participants who were permanent residents in 31 provinces were designed to interviewed in this national biomonitoring (152 monitoring sites × 3 survey units × 2 sexes × 6 age groups × 4 persons = 21,888 persons) in 2017-2018. Unlike the US National Health and Nutrition Examination Survey, the CNHBM will follow the same participants in subsequent cycles allowing for dynamic, longitudinal data sets for epidemiologic follow-up. Each survey cycle of CNHBM will last 2 years and each subsequent cycle will occur 3 years after the prior cycle's completion. RESULTS In 2017-2018, the CNHBM created a large cohort of Chinese citizens that included districts/counties questionnaire, community questionnaire collecting information on villages/communities, individual questionnaire, household questionnaire, comprehensive medical examination, and collection of blood and urine samples for measurement of clinical and exposure biomarkers. A total of 21,746 participants were finally included in CNHBM, accounting for 99.4% of the designed sample size; and 152 PSUs questionnaires, 454 community questionnaires, 21,619 family questionnaires, 21,712 cases of medical examinations, 21,700 individual questionnaires, 21,701 blood samples and 21,704 urine samples were collected, respectively. Planned analyses of blood and urine samples were to measure both inorganic and organic chemicals, including 13 heavy metals and metalloids, 18 poly- and per-fluorinated alkyl substances, 12 phthalate metabolites, 9 polycyclic aromatic hydrocarbons metabolites, 4 environmental alkylated phenols, and 2 benzene metabolites. CONCLUSIONS CNHBM established the first nationally representative, prospective cohort in the Chinese population to understand the baseline and trend of internal exposure of environmental chemicals in general population, and to understand environmental toxicity.

Abstract
Due to continuous spread of coronavirus disease 2019 (COVID-19) worldwide, long-term effective prevention and control measures should be adopted for public transport facilities, as they are increasing in popularity and serve as the principal modes for travel of many people. The human infection risk could be extremely high due to length of exposure time window, transmission routes and structural characteristics during travel or work. This can result in the rapid spread of the infection. Based on the transmission characteristics of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the nature of public transport sites, we identified comprehensive countermeasures toward the prevention and control of COVID-19, including the strengthening of personnel management, personal protection, environmental cleaning and disinfection, and health education. Multi-pronged strategies can enhance safety of public transportation. The prevention and control of the disease during the use of public transportation will be particularly important when all countries in the world resume production. The aim of this study is to introduce experience of the prevention and control measures for public transportation in China to promote the global response to COVID-19.

Abstract
As the number of Coronavirus Disease (2019) (COVID-19) cases increase globally, countries are taking more aggressive preventive measures against this pandemic. Transmission routes of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) include droplet and contact transmissions. There are also evidence of transmission through aerosol generating procedures (AGP) in specific circumstances and settings. Institutionalized populations without mobility and living in close proximity with unavoidable contact are especially vulnerable to higher risks of COVID-19 infection, such as the elderly in nursing homes, children in orphanages, and inmates in prisons. In these places, higher prevention and control measures are needed. In this study, we proposed prevention and control strategies for these facilities and provided practical guidance for general measures, health management, personal protection measures, and prevention measures in nursing homes, orphanages, and prisons, respectively.

Abstract
Objective: To investigate the predictive factors of poor prognosis in children with acute kidney injury (AKI) treated with renal replacement therapy (RRT). Methods: In this retrospective case-control study, the clinical data were collected from 134 pediatric patients (82 male, 52 female) with AKI treated with RRT in six tertiary hospitals from May 2015 to June 2018. According to the serum creatinine level at discharge, the patients were divided into the favorable outcome group and unfavorable outcome group. The data of sex, age, primary diseases, AKI stage, time from diagnosis of AKI to start of RRT (h) and whether to start RRT within 24 hours, urine volume and complications between the two groups were compared. Continuous variables were compared by t test and Mann-Whitney U test, and percentage or proportions were compared by Chi square test. The predictive factors of adverse prognosis were analyzed by using univariate and unconditional binary logistic regression analysis. Results: The average age of the 134 AKI patients was (6±4) years. There were 114 patients (85.0%) in the favorable outcome group and 20 patients (15.0%) in the unfavorable outcome group. No statistically significant differences were found between the two groups in terms of sex (χ(2)=2.596, P=0.107), age (t=0.718, P=0.474), primary disease (χ(2)=2.076, P=0.722), AKI stage (χ(2)=0.004, P=0.998), time from diagnosis of AKI to start RRT (h) (P=0.745), whether to start RRT within 24 hours (χ(2)=0.016, P=0.899), urine volume (χ(2)=3.118, P=0.374), fluid overload (χ(2)=0.014, P=0.905), multiple organ dysfunction syndrome (MODS) (χ(2)=2.972, P=0.085), acidosis (χ(2)=3.204, P=0.073), hyperkalemia (χ(2)=2.829, P=0.093), the level of blood urea nitrogen (t=1.351, P=0.179) and serum creatinine (P=0.901) at the beginning of RRT. In the unfavorable outcome group, the proportion of patients with mechanical ventilation (45.0% (9/20) vs. 12.3% (14/114), χ(2)=12.811, P<0.01) and the incidence of extra organ injury (≥3) (30.0% (6/20) vs. 10.5% (12/114), χ(2)=6.365, P=0.041) were higher than those in the favorable outcome group. Logistic regression analysis showed that mechanical ventilation (OR=12.540, 95%CI: 3.376-46.577, P<0.01) and hyperkalemia (OR=4.611, 95%CI: 1.265-16.805, P=0.021) were the predictive factors of poor prognosis in patients with AKI treated with RRT. Conclusion: Mechanical ventilation and hyperkalemia may predict a poor prognosis in AKI patients treated with RRT.

Abstract
There is an urgent need for vaccines against coronavirus disease 2019 (COVID-19) because of the ongoing SARS-CoV-2 pandemic. Among all approaches, a messenger RNA (mRNA)-based vaccine has emerged as a rapid and versatile platform to quickly respond to this challenge. Here, we developed a lipid nanoparticle-encapsulated mRNA (mRNA-LNP) encoding the receptor binding domain (RBD) of SARS-CoV-2 as a vaccine candidate (called ARCoV). Intramuscular immunization of ARCoV mRNA-LNP elicited robust neutralizing antibodies against SARS-CoV-2 as well as a Th1-biased cellular response in mice and non-human primates. Two doses of ARCoV immunization in mice conferred complete protection against the challenge of a SARS-CoV-2 mouse-adapted strain. Additionally, ARCoV is manufactured as a liquid formulation and can be stored at room temperature for at least 1 week. ARCoV is currently being evaluated in phase 1 clinical trials.

Abstract
The Wnt/β-catenin pathway is among the most frequently altered signaling networks in human cancers. Despite decades of preclinical and clinical research, efficient therapeutic targeting of Wnt/β-catenin has been elusive. RNA interference (RNAi) technology silences genes at the mRNA level and therefore can be applied to previously undruggable targets. Lipid nanoparticles (LNP) represent an elegant solution for the delivery of RNAi-triggering oligonucleotides to disease-relevant tissues, but have been mostly restricted to applications in the liver. In this study, we systematically tuned the composition of a prototype LNP to enable tumor-selective delivery of a Dicer-substrate siRNA (DsiRNA) targeting CTNNB1, the gene encoding β-catenin. This formulation, termed EnCore-R, demonstrated pharmacodynamic activity in subcutaneous human tumor xenografts, orthotopic patient-derived xenograft (PDX) tumors, disseminated hematopoietic tumors, genetically induced primary liver tumors, metastatic colorectal tumors, and murine metastatic melanoma. DsiRNA delivery was homogeneous in tumor sections, selective over normal liver and independent of apolipoprotein-E binding. Significant tumor growth inhibition was achieved in Wnt-dependent colorectal and hepatocellular carcinoma models, but not in Wnt-independent tumors. Finally, no evidence of accelerated blood clearance or sustained liver transaminase elevation was observed after repeated dosing in nonhuman primates. These data support further investigation to gain mechanistic insight, optimize dose regimens, and identify efficacious combinations with standard-of-care therapeutics.

Abstract
Abstract
MYC and CTNNB1 are well-characterized drivers of numerous tumor types. Human and preclinical genetic evidence suggest that pharmacological intervention to reduce transactivation of MYC and CTNNB1-regulated genes would yield therapeutic benefit to many cancer patients. Since the proteins encoded by these genes are challenging to target via conventional modalities, progress in new therapeutic agents has been slow despite decades of research. RNA interference technology has enabled the inhibition of previously-undruggable genetic targets at the mRNA level, and has advanced to clinical development for several indications. DCR-MYC is a Phase I-stage lipid nanoparticle (LNP)-formulated Dicer substrate siRNA (DsiRNA), representing a potent class of RNAi triggers being developed by Dicerna Pharmaceuticals. Here we describe new preclinical data that increase our understanding of the parameters that impact tumor delivery and activity of DsiRNA. We demonstrate that the cationic lipid and PEG-lipid components of Dicerna's unique EnCore LNP platform can be modulated to improve delivery of DsiRNA to both orthotopic and spontaneous liver tumors, as well as xenograft tumors of diverse non-hepatic tissue origin. Characterization of LNP formulations with respect to plasma PK, tissue exposure and target mRNA knockdown was employed towards understanding the pharmacology of LNP-mediated tumor delivery.

Abstract
Abstract
Hepatoblastoma (HB), the commonest pediatric liver tumor is frequently associated with an N-terminal deletion in the CTNNB1 gene, which encodes stable β-catenin and promotes nuclear localization and transactivation activity. In 80% of patients, nuclear localization of β-catenin and Yes Associated Protein (YAP), a Hippo-related transactivator, is seen together. Further, stable hepatic co-expression of Δ90-CTNNB1 and active-YAP in mice causes rapid and aggressive HB. Dicer-substrate siRNAs (DsiRNAs) are potent RNA interference (RNAi) triggers that that are efficacious in preclinical tumor models of diverse origin, and are currently under clinical evaluation. To determine if CTNNB1-targeting DsiRNAs have potential as a therapy in HB, we encapsulated this oligonucleotide payload into lipid nanoparticles (LNPs), and systemically administered into mice bearing CTNNB1/YAP-induced HB. The LNP platform used, termed EnCore (because of its specific Envelope and Core lipid components), enables high encapsulation efficiency, long-term stability, and consistent analytical criteria. Downstream of LNP-mediated DsiRNA delivery, both qPCR and in situ hybridization were used to visualize changes in CTNNB1 expression in both tumor and normal liver. Robust and specific silencing of CTNNB1 mRNA was achieved in the tumors. The distribution of mRNA knockdown within each tumor nodule suggests efficient extravasation and internalization of the LNP and its payload into the tumor parenchyma, in contrast to previous reports of vascular-channel limited nanoparticle accumulation in tumors. Intriguingly, a “liver-centric” LNP formulation, which delivers cargo efficiently to a normal liver due to rapid hepatic extraction and apolipoprotein-mediated internalization, was inactive in the tumors. Further evaluation demonstrated efficacy of β-catenin targeting in this model. In conclusion, we report a highly relevant modality of RNAi delivery in a mouse model of hepatoblastoma to target a classically-undruggable oncogene.

Abstract
The facial asymmetry associated with vertical maxillary excess and mandibular prognathism is one of the more complicated types in the field of oral and maxillofacial surgery. The purpose of this study was to investigate the efficacy of combined orthognathic surgeries, together with guiding templates and splints fabricated by rapid prototyping technique, for the correction of facial asymmetry. Fourteen patients with facial asymmetry associated with vertical maxillary excess and mandibular prognathism were included. A maxillary Le Fort I osteotomy, a sagittal split ramus osteotomy on the shorter side of the face, and an intraoral vertical ramus osteotomy on the longer side of the face were performed with the aid of guiding templates and splints fabricated by rapid prototyping technique. Parameters reflecting maxillary canting, ramal inclination, mandibular deviation, and chin inclination were measured before surgery, 7 days after surgery, and 1 year after surgery, and compared. Significant differences in these parameters were found between the two sides preoperatively, whereas no differences were observed postoperatively. Facial asymmetry was corrected in all patients with satisfactory outcomes. In conclusion, combined orthognathic surgery and guiding templates and splints can offer improvements in accuracy, complexity, and duration over traditional procedures for the correction of facial asymmetry associated with vertical maxillary excess and mandibular prognathism.

Abstract
Abstract
Although there are now multiple successful examples of targeted therapeutics in cancer, many key protein targets have remained largely ‘undruggable’, including transcription factors such as B-catenin (CTNNB1) and MYC. B-catenin mediates Wnt signaling, which is overactive in many cancers including hepatocarcinoma (HCC). RNAi offers a way to reach such undruggable targets by inhibiting their expression at the mRNA level. Dicer substrate siRNAs (“DsiRNAs”) can be particularly effective for gene silencing. DsiRNAs are longer than conventional siRNAs, and therefore are substrates for processing by Dicer, after which the product RNA duplexes are incorporated into RISC, leading to target mRNA knockdown. We have used DsiRNAs to target B-catenin, MYC, and other key genes in HCC and other cancers. Through large-scale DsiRNA screening, we have identified a series of high potency DsiRNAs with picomolar to sub-picomolar IC50 values for mRNA knockdown. Lead DsiRNAs fully tolerated extensive 2’-OMe modification, retaining high potency, and lacked detectable immunostimulatory activity. To test the effect of target gene knockdown on tumor growth in vivo, we used a lipid nanoparticle (LNP) delivery system. LNP/DsiRNA particles effectively delivered to tumors in mouse tumor models, leading to rapid knockdown of target gene mRNA and protein. Knockdown of B-catenin, MYC, and other target genes strongly inhibited tumor growth. B-catenin knockdown also strongly reduced expression of the B-catenin-regulated genes Axin2 and MYC, a potential mechanism for tumor inhibition. In summary, we have developed high potency DsiRNAs to cancer target genes, and effectively delivered these DsiRNAs to tumors in vivo, resulting in inhibition of target gene expression and inhibition of tumor growth. DsiRNA therapeutics show promise as novel agents for reaching traditionally undruggable target genes.

Abstract
We report that radiation enhances the antitumor efficacy of the oncolytic adenovirus vector VRX-007 in Syrian hamster tumors. We used tumor-specific irradiation of subcutaneous tumors and compared treatment options of radiation alone or combined with VRX-007 and cyclophosphamide (CP). Radiation therapy further augmented the VRX-007-mediated inhibition of tumor growth, in both CP-treated and non-CP-treated hamsters, even though radiation did not lead to increased viral replication in tumors when compared to those treated with VRX-007 alone. Moreover, tumor growth inhibition was similar in tumors irradiated either one week before or after injection with VRX-007, which suggests that radiation exerts its antitumor effect independently from vector therapy. Thus, our results demonstrate that these two therapies do not have to be provided simultaneously to enhance their combined effectiveness against subcutaneous hamster tumors.

Abstract
BACKGROUND With the idea of "replacing lost tissure with similar tissure in kind", vessel-pedicled palate mucosal flap, pedicled buccal musculomucosal flap and adjacent tongue musculomucosal flap could be the ideal approaches to soft palate reconstruction. AIM To assess the adjacent tongue musculomucosal flap for soft palate reconstruction. PATIENTS AND METHODS From August 2010 to July 2011, we applied tongue musculomucosal flap for soft palate reconstruction in three patients with Obstructive Sleep Apnoea/Hypopnoes Syndrome (OSAHS) in order to release OSAHS symptom by glossal volume reduction. RESULTS All patients recovered from intraoral operations with good objective as subjective speech and swallowing. Suffice it to say that OSAHS symptom was released for these patients. CONCLUSIONS Here we provide a case to deal with problems related to OSAHS symptom when one works on oral surgery or reconstructing oral structure.

Abstract
Interleukin-18 (IL-18) is a potent proinflammatory cytokine, which can promote hepatitis B virus clearance. The latest studies find that genetic polymorphisms near the IL-28B gene are strongly associated with sustained viral response and spontaneous viral clearance in patients with chronically infected hepatitis C and hepatitis B. We investigated the effect of rs187238 and rs1946518 in IL-18 gene and rs8099917 in IL-28B gene on HBV recurrence in liver transplant patients. A total of 200 liver transplant recipients and relevant donors were enrolled in this study. The patients' mean follow-up was 39 month (range 10-65 month). All liver transplant recipients were in a stable stage. The total recipients (n = 200) were divided into end-stage liver disease secondary to hepatitis B (n = 140) and end-stage liver disease secondary to other diseases (n = 60) before transplantation. Recipients (n = 140) with hepatitis B before transplantation were defined to nonHBV recurrence group (n = 119) or HBV recurrence group (n = 21), which was positive for HBsAg or elevatory in HBV DNA (>2.0 × 10(2) IU mL(-1)) after transplantation. For the recipients (n = 140) had hepatitis B before transplantation, we studied the single-nucleotide polymorphisms (SNPs) of IL-18 gene (rs187238 and rs1946518) and IL-28B gene (rs8099917) by high-resolution melting (HRM) curve analysis. The serum levels of IL-18 and IFN-γ were tested by ELISA. The serums levels of IFN-γ were lower in HBV recurrence group than that in nonHBV recurrence group (P < 0.01). The genotype of IL-28B gene rs8099917 was associated with alanine aminotransferase (ALT) levels and aspartate aminotransferase (AST) levels in HBV-related liver transplant recipients (n = 140). The recipients with allele G (GG+GT) had higher ALT and AST levels (P < 0.05). No association was found between IL-18 gene and IL-28B gene polymorphisms with HBV recurrence in the liver transplant recipients or the donors. We identified that the IFN-γ was a protective factor of HBV recurrence after liver transplantation. The allele G of rs8099917 was associated with hepatitis B-related hepatocytes injury. The rs8099917 G allele subgroup should reinforce antiviral therapy.

Abstract
OBJECTIVE To demonstrate and promote the fluorine-fixing technology of the coal burning on a calcium-based compound as the additive for briquettes made in the coal-burning fluorosis area, in order to evaluate the effects of fluorine-fixing and indoor air pollutants condition. METHODS The briquettes added calcium-based fluorine sorbent were used for heating and cooking. In the meantime, the figures on various components in briquettes and fluorine content in coal slag as well as concentrations of indoor air fluorides, sulfur dioxide and PM10 were calculated. RESULTS On the basis of the coal burning fluorine-fixing pilot experiment, 100 households in Longli County, Guizhou Province were selected as the experimental group for coal burning fluorine-fixing demonstration and promotion. When the burning calcium-based fluorine-fixing bitumites were made into coalballs, the average fluorine-fixing ratios in demonstration and promotion were 77.26%. The average reduction ratios of indoor air pollutants, fluorides were 53.3% -73.8%, sulfur dioxide were 62.8% -91.1% and PM10 were 9.5% -41.4%. There were 10% increases in the cost of briquettes due to the addition of calcium-based fluorine sorbent in demonstration and promotion. CONCLUSION The preparation process of calcium-based fluorine-fixing briquettes was simple and highly flammable and it was applicable to regions abundant in bitumite.

Abstract
BACKGROUND The fluorosis derived from coal burning is a very serious problem in China. By using fluorine-fixing technology during coal burning we are able to reduce the release of fluorides in coal at the source in order to reduce pollution to the surrounding environment by coal burning pollutants as well as decrease the intake and accumulating amounts of fluorine in the human body. The aim of this study was to conduct a pilot experiment on calcium-based fluorine-fixing material efficiency during coal burning to demonstrate and promote the technology based on laboratory research. METHODS A proper amount of calcium-based fluorine sorbent was added into high-fluorine coal to form briquettes so that the fluorine in high-fluorine coal can be fixed in coal slag and its release into atmosphere reduced. We determined figures on various components in briquettes and fluorine in coal slag as well as the concentrations of indoor air pollutants, including fluoride, sulfur dioxide and respirable particulate matter (RPM), and evaluated the fluorine-fixing efficiency of calcium-based fluorine sorbents and the levels of indoor air pollutants. RESULTS Pilot experiments on fluorine-fixing efficiency during coal burning as well as its demonstration and promotion were carried out separately in Guiding and Longli Counties of Guizhou Province, two areas with coal burning fluorosis problems. If the calcium-based fluorine sorbent mixed coal was made into honeycomb briquettes the average fluorine-fixing ratio in the pilot experiment was 71.8%. If the burning calcium-based fluorine-fixing bitumite was made into a coalball, the average of fluorine-fixing ratio was 77.3%. The concentration of fluoride, sulfur dioxide and PM10 of indoor air were decreased significantly. There was a 10% increase in the cost of briquettes due to the addition of calcium-based fluorine sorbent. CONCLUSIONS The preparation process of calcium-based fluorine-fixing briquette is simple yet highly flammable and it is applicable to regions with abundant bitumite coal. As a small scale application, villagers may make fluorine-fixing coalballs or briquettes by themselves, achieving the optimum fluorine-fixing efficiency and reducing indoor air pollutants providing environmental and social benefits.

Abstract
Preclinical biodistribution studies with INGN 007, an oncolytic adenovirus (Ad) vector, supporting an early stage clinical trial were conducted in Syrian hamsters, which are permissive for Ad replication, and mice, which are a standard model for assessing toxicity and biodistribution of replication-defective (RD) Ad vectors. Vector dissemination and pharmacokinetics following intravenous administration were examined by real-time PCR in nine tissues and blood at five time points spanning 1 year. Select organs were also examined for the presence of infectious vector/virus. INGN 007 (VRX-007), wild-type Ad5 and AdCMVpA (an RD vector) were compared in the hamster model, whereas only INGN 007 was examined in mice. DNA of all vectors was widely disseminated early after injection, but decayed rapidly in most organs. In the hamster model, DNA of INGN 007 and Ad5 was more abundant than that of the RD vector AdCMVpA at early times after injection, but similar levels were seen later. An increased level of INGN 007 and Ad5 DNA but not AdCMVpA DNA in certain organs early after injection, and the presence of infectious INGN 007 and Ad5 in lung and liver samples at early times after injection, strongly suggests that replication of INGN 007 and Ad5 occurred in several Syrian hamster organs. There was no evidence of INGN 007 replication in mice. In addition to providing important information about INGN 007, the results underscore the utility of the Syrian hamster as a permissive immunocompetent model for Ad5 pathogenesis and oncolytic Ad vectors.

Abstract
BACKGROUND Trace elements are involved in metabolic processes and oxidation-reduction reactions in the central nervous system and could have a possible effect on cognitive function. The relationship between trace elements measured in individual biological samples and cognitive function in an elderly population had not been investigated extensively. METHODS The participant population is part of a large cohort study of 2000 rural elderly Chinese persons. Six cognitive assessment tests were used to evaluate cognitive function in this population, and a composite score was created to represent global cognitive function. Trace element levels of aluminum, calcium, cadmium, copper, iron, lead, and zinc were analyzed in plasma samples of 188 individuals who were randomly selected and consented to donating fasting blood. Analysis of covariance models were used to assess the association between each trace element and the composite cognitive score adjusting for demographics, medical history of chronic diseases, and the apolipoprotein E (APOE) genotype. RESULTS Three trace elements-calcium, cadmium, and copper-were found to be significantly related to the composite cognitive score. Increasing plasma calcium level was associated with higher cognitive score (p <.0001). Increasing cadmium and copper, in contrast, were significantly associated with lower composite score (p =.0044 and p =.0121, respectively). Other trace elements did not show significant association with the composite cognitive score. CONCLUSIONS Our results suggest that calcium, cadmium, and copper may be associated with cognitive function in the elderly population.

Abstract
The surface structure of films prepared by casting aqueous solutions of mixtures of water soluble chitosan (WSC) and amylose as well as a fully deacetylated chitosan was studied. Zeta potential measurements indicated that the surface of WSC and fully deacetylated chitosan films is positively charged but very weakly, whereas, a film of amylose blended with WSC exhibited an obvious positive charge. X-ray photoelectron spectra of these films suggest that less amino groups are exposed on the surface of WSC and fully deacetylated chitosan films, whereas, more amino groups are exposed on the surface of a WSC film blended with amylose. A sheet structure in which free amino groups are less exposed on the surface of the film of WSC or fully deacetylated chitosan is proposed. This accounts for the loss of antibacterial activity of chitosan on the WSC film surface. When blended with amylose, the morphology of the film may be disrupted, resulting in strong antibacterial properties.

Abstract
OBJECTIVE To set up a method for simultaneous determination of eight elements in grain and vegetable by microwave digestion-inductively coupled plasma-mass spectrometry (ICP-MS). METHODS Food samples were digested in a microwave digestion system with nitric acid solution, and contents of Al, As, Cd, Cu, Pb, Zn, Fe and Ca in the digestion solutions were determined simultaneously by ICP-MS. RESULTS The national standard reference materials such as mussel (GBW08571) and wheat powder (GBW08503B) were applied in the process of sample analysis, and the determination values of the standard reference materials were within the certified values. The accuracy of the method was 79.4%-111.5%, and the RSD was less 1.1%-6.6%. The recoveries of the spiked samples were 93.5%-110%. In order to reduce the matrix interference, the calibration of internal standard and the sample dilution were introduced for ICP-MS. CONCLUSION This method has simple operation, rapid analysis, high accuracy, and reliable, and can be applied in simultaneous determination of multiple elements in food samples.

Abstract
Selenium is a trace element associated with antioxidant activity and is considered to be a protective agent against free radicals through enhanced enzyme activity. Studies on selenium and cognitive function or Alzheimer's disease have yielded inconsistent results. A cross-sectional survey of 2,000 rural Chinese aged 65 years or older from two provinces in the People's Republic of China was conducted from December 2003 to May 2005 by use of the Community Screening Instrument for Dementia, the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Word List Learning Test, the Indiana University Story Recall Test, the Animal Fluency Test, and the Indiana University Token Test. Over 70% of the study participants have lived in the same village since birth. Nail samples were collected and analyzed for selenium contents. Analysis-of-covariance models were used to estimate the association between quintile selenium levels measured in nail samples and cognitive test scores, with adjustment for other covariates. Lower selenium levels measured in nail samples were significantly associated with lower cognitive scores (p < 0.0087 for all tests) except the Animal Fluency Test (p = 0.4378). A dose-response effect of selenium quintiles was also seen for those significant associations. Results in this geographically stable cohort support the hypothesis that a lifelong low selenium level is associated with lower cognitive function.

Abstract
OBJECTIVE To develop a method for determination of total sulfur in coal by ion chromatography. METHODS To pretreat the coal by high-temperature combustion with oxygen-flow in tube furnace, and the sulfur with any from in coal was oxidated and converted into oxid of sulfur, which became sulfate after oxidated by H2O2 absorption solution. The separation of sulfate was achieved on DionexAS12A anion exchange column with a carbonate eluent, and the detection is performed by the suppressed conductivity detector with the injection volume of 50 microl. The total sulfur in coals were obtained from the determined results. RESULTS The method had been compared with the National Standard Method "High-Temperature Combustion--Neutralization Method for Determination of Total Sulfur in Coal (GB/T214-1996)", and the RSD of the method was less than 2% . This method had good relativity of the linearity (r = 0.9998) at the range of 0 to approximately 15 microg/ml for sulfate. Two kinds of national certified reference materials (GBW11104c and GBWl1110d) were determined, and the RSD were 1.92% and 0.47% respectively. CONCLUSION Ion chromatography for determination of total sulfur in coal has simple operation, high accuracy, and fast analysis, and can be applied in determination of total sulfur in coal.

Abstract
Bromate is a common disinfection by-product produced from the ozonation of source water containing bromide. An ion exchange chromatographic method with suppressed conductivity detection for the determination of trace bromate in drinking water was developed. The separation of the bromate in drinking water was achieved on a Metrosep A Supp 5 anion exchange column and a Metrosep A Supp 4/5 Guard column with a carbonate eluent. A new dual suppressed system, an MSM II chemical suppressor combined with a CO2 suppressor, was used to suppress the background conductivity, and to improve the detection limit of bromate. Ion chromatographic experiments were carried out by using a Metrosep A Supp 5 anion exchange column with a suppressed conductivity detector and an eluent of 3.2 mmoL/L Na2CO3-1.0 mmol/L NaHCO3 at a flow rate of 0.65 mL/min. This method had good linearity (r = 0.9999) in the range of 5-100 microg/L and high precision (relative standard deviation (RSD) < 4% ) for three concentration levels of bromate. The average recoveries of the spiked samples including tap water, pure water and mineral water were 96.1%-107%, and the detection limit for bromate was 0.50 microg/L. This method has a simple operation procedure, good separation results, high sensitivity and good repeatability. It can be used as a standard method for the determination of bromate in drinking water.

Abstract
A new type of dual-channel PAM fluorometer (ToxY-PAM) was developed for highly sensitive detection of toxic substances in water samples. In conjunction with suspension of unicellular algae as the biotest material, the ToxY-PAM provided a highly rapid and sensitive bioassay test system for the detection of toxic substances in water samples, which could directly or indirectly produce the inhibition of photosynthetic activity in algae. The development process of the detection of toxic substances in water with fluorescence technique, the basic principle and operation of the ToxY-PAM were reviewed in this paper.

Abstract
Mandibular symphyseal defects caused by tumor surgery, trauma, or congenital misshape can produce maxillofacial deformity and functional handicap. Recently, the technique of distraction osteogenesis has become a valuable reconstructive method for craniofacial bone defects. Four adult rhesus monkeys were used in this study. The anterior mandibulectomy (ranged from canine to canine) was performed, and bilateral transport segments (ranged from first premolar to first molar) were created. Custom-made multiplanar distractors were applied for the reconstruction of the monkeys' artificial mandibular symphyseal defects by trifocal distraction osteogenesis. After a delay period of 7 days, the bilateral transport discs were distracted forward and inward simultaneously. Serial X-ray and three-dimensional CT films were taken within the experimental period. Two monkeys were sacrificed at 8 and 16 weeks, respectively, after the completion of distraction. The distracted calluses and united areas between bilateral transport discs were harvested and processed for histological examination. The mandibular symphyseal defects in all animals were repaired successfully and the anterior mandibular contours were similar to the normal ones. Perfect bone regeneration in the distraction gaps was found, and fibro-bony union between the bilateral transport segments was observed in the midline region at 16 weeks after the end of distraction. The success of distraction osteogenesis for repair of mandibular symphseal defects in monkeys by this distractor may provide an alternative method to reconstruct the anterior part of mandible.

Abstract
The previous study showed involvement of spinal glia in tetanically sciatic stimulation-induced long-term potentiation (LTP) of C-fiber-evoked field potentials in the spinal dorsal horn. In the present study, the electrophysiological recording and paw withdrawal threshold (PWT) to von Frey stimulation were assessed following unilaterally tetanically sciatic stimulation in rats. Tetanic stimuli elicited LTP of both A- and C-fiber-evoked field potentials. After stimulation with the same parameter, bilateral PWTs to mechanical stimuli decreased. Intrathecal administration of fluorocitrate (1 nmol/10 microl), an astrocyte inhibitor, partially inhibited tetanic stimulation-induced reduction of bilateral PWTs. A similar effect also occurred at the contralateral side. And this bilateral inhibition of mechanical threshold lasted 8 days. Similarly, intrathecal administration of d-amino acid oxygenase (50 microg/mul, 10 microl), D-serine inhibitor, partially inhibited tetanic sciatic stimulation-induced reduction of bilateral PWTs for 24 h. The results showed that spinal glia plays an important role in bilaterally mechanical allodynia by tetanic sciatic stimulation of the sciatic nerve.

Abstract
Exposure to indoor air pollution from household energy use depends on fuel, stove, housing characteristics, and stove use behavior. We monitored three important indoor air pollutants-respirable particles (RPM), carbon monoxide (CO), and sulfur dioxide (SO2)-for a total of 457 household-days in four poor provinces in China (Gansu, 129 household-days; Guizhou, 127 household-days; Inner Mongolia, 65 household-days; and Shaanxi, 136 household-days), in two time intervals during the heating season to investigate spatial and temporal patterns of pollution. The two provinces where biomass is the primary fuel (Inner Mongolia and Gansu) had the highest RPM concentrations (719 microg/m3 in the single cooking/living/bedroom in Inner Mongolia in December and 351-661 microg/m3 in different rooms and months in Gansu); lower RPM concentration were observed in the primarily coal-burning provinces of Guizhou and Shaanxi (202-352 microg/m3 and 187-361 microg/m3 in different rooms and months in Guizhou and Shaanxi, respectively). Inner Mongolia and Gansu also had higher CO concentrations (7.4 ppm in the single cooking/living/bedroom in Inner Mongolia in December and 4.8-11.3 ppm in different rooms and months in Gansu). Among the two primarily coal-burning provinces, Guizhou had lower concentrations of CO than Shaanxi (1.2-1.8 ppm in Guizhou vs 2.0-13.3 ppm in different rooms and months in Shaanxi). In the two coal-burning provinces, SO2 concentrations were substantially higher in Shaanxi than in Guizhou. Relative concentrations in different rooms and provinces indicate that in the northern provinces heating is an important source of exposure to indoor pollutants from energy use. Day-to-day variability of concentrations within individual households, although substantial, was smaller than variation across households. The implications of the findings for designing environmental health interventions in each province are discussed.
