Abstract
Luteolin is a potent anti-colorectal cancer chemical. However, its effectiveness is hindered by its poor solubility in water and fat, and it is easy to degrade by gastrointestinal enzymes. In this study, a nano-composite carrier, NH2-MIL-101(Fe)@GO (MG), based on aminated MIL-101(Fe) and graphene oxide (GO) was developed and evaluated. This carrier co-delivered luteolin and matrine, while marine was used to balance the pH for the nano-preparation. The loading capacities for luteolin and matrine were approximately 9.8% and 14.1%, respectively. Luteolin's release at pH = 5 was significantly higher than at pH = 7.4, indicating it had an acidic pH response release characteristic. Compared to MOF and GO alone, MG and NH2-MIL-101(Fe)@GO@Drugs (MGD) enhanced anti-cancer activity by inhibiting tumor cell migration, increasing ROS generation, and upregulating the expression of Caspase-3 and Caspase-9. In conclusion, this study contributes new ideas and methods to the treatment strategy of multi-component anti-colorectal cancer therapy. It also advances drug delivery systems and supports the development of more effective and targeted treatment approaches for colorectal cancer.

Abstract
Using a novel method of isochronous mass spectrometry, the masses of ^{62}Ge, ^{64}As, ^{66}Se, and ^{70}Kr are measured for the first time, and the masses of ^{58}Zn, ^{61}Ga, ^{63}Ge, ^{65}As, ^{67}Se, ^{71}Kr, and ^{75}Sr are redetermined with improved accuracy. The new masses allow us to derive residual proton-neutron interactions (δV_{pn}) in the N=Z nuclei, which are found to decrease (increase) with increasing mass A for even-even (odd-odd) nuclei beyond Z=28. This bifurcation of δV_{pn} cannot be reproduced by the available mass models, nor is it consistent with expectations of a pseudo-SU(4) symmetry restoration in the fp shell. We performed ab initio calculations with a chiral three-nucleon force (3NF) included, which indicate the enhancement of the T=1 pn pairing over the T=0 pn pairing in this mass region, leading to the opposite evolving trends of δV_{pn} in even-even and odd-odd nuclei.

Abstract
Bones are categorized as the second most prevalent location of extra-hepatic metastasis in Hepatocellular Carcinoma (HCC), which is linked to an extremely poor prognosis due to limited therapeutic options. N6-methyladenosine (m6A) is a prominent modification involved in HCC, but the exact mechanisms on how m6A modifications induce HCC bone metastases (BM) remain unclear. The key modulators responsible for the abundant m6A RNA modification-induced HCC BM was found to be the METTL3 and YTHDF1. The expression of Anillin actin-binding protein (ANLN) was dramatically higher in HCC with BM tissues, and its messenger RNA (mRNA) stability was enhanced via m6A epitranscriptomic regulation by METTL3 and YTHDF1. High METTL3 and YTHDF1 expression along with nuclear ANLN protein was clinically correlated with BM in HCC patients. Furthermore, HCC BM was attributed to over-expression of nuclear ANLN forming a transcriptional complex with SP1 which enhanced KIF2C transcriptional activity to activate the mTORC1 pathway, therefore increased the expression of RANKL and disproportionated RANKL-OPG expression in bone microenvironment leading to malignant neoplasms invade bone tissue. In addition, inhibition of ANLN m6A modification by DZNeP attenuated HCC BM. This data provides meaningful understanding of the modulation and association of m6A epitranscriptomic-regulated BM in HCC, and moreover, defines potentially valuable therapeutic targets.

Abstract
In order to investigate developmental coordination disorder (DCD) of kindergarten children in Zhejiang province, 200 ordinary kindergartens were randomly selected by stratified random sampling in 11 prefecture-level cities of Zhejiang Province, and 38 900 children from 1 000 classes in each grade were then randomly selected into the study from June 2019 to December 2019. The Little DCD Questionnaire and a self-designed questionnaire were used to screen the DCD of those children. There were 36 807 valid questionnaires, and 6.50% (2 391/36 807) of them were positive results. The results showed that boy, age ≤5 years, overweight or obesity, left handedness, comorbidity with motor or developmental disorders and premature infants were risk factors of DCD in children. As for parents and families, maternal gestational age<20 years, maternal overweight or obesity before pregnancy, low-middle level education of parents, direct family and low income of family were also associated with DCD in children. Therefore, it is necessary to conduct early prevention and intervention strategies targeting on identified risk factors among relevant population.

Abstract
The Rare-RI Ring (R3) is a recently commissioned cyclotronlike storage ring mass spectrometer dedicated to mass measurements of exotic nuclei far from stability at Radioactive Isotope Beam Factory (RIBF) in RIKEN. The first application of mass measurement using the R3 mass spectrometer at RIBF is reported. Rare isotopes produced at RIBF-^{127}Sn, ^{126}In, ^{125}Cd, ^{124}Ag, ^{123}Pd-were injected in R3. Masses of ^{126}In, ^{125}Cd, and ^{123}Pd were measured whereby the mass uncertainty of ^{123}Pd was improved. This is the first reported measurement with a new storage ring mass spectrometry technique realized at a heavy-ion cyclotron and employing individual injection of the preidentified rare nuclei. The latter is essential for the future mass measurements of the rarest isotopes produced at RIBF. The impact of the new ^{123}Pd result on the solar r-process abundances in a neutron star merger event is investigated by performing reaction network calculations of 20 trajectories with varying electron fraction Y_{e}. It is found that the neutron capture cross section on ^{123}Pd increases by a factor of 2.2 and β-delayed neutron emission probability, P_{1 n}, of ^{123}Rh increases by 14%. The neutron capture cross section on ^{122}Pd decreases by a factor of 2.6 leading to pileup of material at A=122, thus reproducing the trend of the solar r-process abundances. The trend of the two-neutron separation energies (S_{2n}) was investigated for the Pd isotopic chain. The new mass measurement with improved uncertainty excludes large changes of the S_{2n} value at N=77. Such large increase of the S_{2n} values before N=82 was proposed as an alternative to the quenching of the N=82 shell gap to reproduce r-process abundances in the mass region of A=112-124.

Abstract
In the egg production industry, trace elements are required as additional dietary supplements to play vital roles in performance and egg quality. Compared to inorganic microelements (ITs), appropriate dose of organic trace microelements (OTs) are environmentally friendly and sufficient to satisfy the needs of hens. In order to evaluate the extent to which low-dose OTs replace whole ITs, the effects of organic copper, zinc, manganese, and iron compound on the performance, eggshell quality, antioxidant capacity, immune function, and mineral deposition of old laying hens were investigated. A total of 1 080 57-week-old Jing Hong laying hens were assigned to five groups with six replicates of 36 layers each for an 8-week experimental period. The birds were fed either a basal diet (control treatment (CT)) or the basal diet supplemented with commercial levels of inorganic trace elements (IT 100%) or the equivalent organic trace elements at 20%, 30%, and 50% of the inorganic elements (OT 20%, OT 30%, and OT 50%, respectively). Results showed that compared with those in the CT treatment, feeding hens with inorganic or organic microelement diet had significant effects on the eggshell quality, antioxidant capacity, immune function, and mineral deposition of old laying hens (P < 0.05). The eggshell strength and ratio between OT 30%, OT 50%, and IT 100% were similar at weeks 4 and 8, and the eggshell thickness of these groups was also similar at weeks 6 and 8. At week 8, the eggshell colour in OT 50% was darker than that in IT 100%. The mineral content in the eggshells of OT 50% and IT 100% significantly increased (P < 0.001), with no significant difference in effective thickness, mammillary thickness, and mammillary knob width between groups. There were no differences in the malondialdehyde content, total antioxidant capacity, and total superoxide dismutase activity in serum between OT 30%, OT 50%, and IT100%. While the catalase activities, the interleukin-1β, interleukin-10, immunoglobulin G, and immunoglobulin M concentrations in serum were not significantly different between OT 50% and IT 100%. The mineral contents in the faeces of the organic groups were considerably reduced compared with those in IT 100% (P < 0.001). In conclusion, dietary supplementation with 30-50% organic compound microelements has the potential to replace 100% inorganic microelements in the hen industry for improving eggshell quality, mineral deposition in the eggshell, antioxidant capacity, and immune function, and reducing emissions to the environment without negative effects on laying performance.

Abstract
N6-methyladenosine (m6A) modification, the most abundant internal methylation of eukaryotic RNA transcripts, is critically implicated in RNA processing. There is extensive evidence indicating that long non-coding RNAs (lncRNAs) serve as key regulators of oncogenesis and tumor progression in humans. Through prior study has assessed that LIFR-AS1 plays a key role in various kinds of malignant tumors. However, the exact role of m6A induced LIFR-AS1 in pancreatic cancer (PC) and its potential molecular mechanisms remain largely unknown. In this study, we determined that PC cell lines and tumors exhibit increased LIFR-AS1 expression that correlates with larger tumor size, lymph node metastasis, and more advanced TNM stage. Functionally, loss-of-function studies indicated that LIFR-AS1 knockdown decreased the proliferation, migration, and invasion of PC cells in vitro. Mechanistically, we found that METTL3 induced m6A hyper-methylation on the 3' UTR of LIFR-AS1 to enhance its mRNA stability and LIFR-AS1 could directly interact with miR-150-5p, thereby indirectly up-regulating VEGFA expressions within cells. Through rescue experiments, we were able to confirm that the unfavorable impact of LIFR-AS1 knockdown on VEGFA /PI3K/Akt Signaling could be reversed via the inhibition of miR-150-5p expression. Together, these findings indicate that a noval m6A-LIFR-AS1 axis promotes PC progression at least in part via regulation of the miR-150-5p/VEGFA axis, indicating that this regulatory axis may be a viable clinical target for the treatment of PC.

Abstract
Objective: To study the characteristics of wideband tympanometry(WBT) and its application value in the diagnosis of otitis media with effusion(OME) in young children. Methods: We compared wideband acoustic energy absorbance(EA) under peak pressure in young children with OME(190 ears) and healthy control subjects(121 ears) from Ninth People's Hospital of Shanghai Jiaotong University School of Medicine between January 2018 and June 2020. Both groups were divided into three groups, 1-6 months, 7-36 months and 37-72 months. SPSS 20.0 statistical software was used to analyze and compare the EA parameters between OME children of different months and the control group. Receiver operating characteristic (ROC)curve was used to analyze the diagnostic value of WBT in young children with OME. Results: There were significant differences in EA among three OME groups from 500 Hz to 2 000 Hz(P<0.05).Compared with the control groups, EA of 1-6 m OME group decreased significantly below 4 000 Hz(P<0.05), EA of 7-36 m OME group decreased significantly at 545-1 600 Hz(P<0.05), EA of 37-72 m OME group decreased significantly above 545 Hz(P<0.05).ROC curve indicated that EA at 1 000 Hz had the greatest diagnostic value (AUC was 0.890), followed by 1 500 Hz and the range of 500-2 000 Hz (AUC was 0.883 and 0.881, respectively).EA at 1 000 Hz with a cutoff value of 0.55 had the best diagnostic sensitivity of 90.8%, which was higher than conventional tympanometry (85.8%). The maximum AUC (0.932) could be obtained by combining EA, peak pressure and admittance amplitude of 226 Hz tympanometry as predictors. Conclusions: EA is significantly decreased in young children with OME. Compared with the conventional single frequency tympanometry, WBT is more accurate in the diagnosis of OME in young children, and the prediction accuracy would be better if combined with 226 Hz tympanometry.

Abstract
In patients with hepatocellular carcinoma (HCC), disease progression and associated bone metastasis (BM) can markedly reduce quality of life. While the long non-coding RNA (lncRNA) zinc finger E-box binding homeobox 1 antisense 1 (ZEB1-AS1) has been shown to function as a key regulator of oncogenic processes in HCC and other tumor types, whether it plays a role in controlling HCC BM remains to be established. In the current study, we detected the significant upregulation of lncZEB1-AS1 in HCC tissues, and we found this expression to be associated with BM progression. When we knocked down this lncRNA in HCC cells, we found that this significantly reduced their migratory, invasive, and metastatic activity both in vitro and in vivo. At a mechanistic level, we found that lncZEB1-AS1 was able to target miR-302b and to thereby increase PI3K-AKT pathway activation and EGFR expression, resulting in the enhanced expression of downstream matrix metalloproteinase genes in HCC cells. In summary, our results provide novel evidence that lncZEB1-AS1 can promote HCC BM through a mechanism dependent upon the activation of PI3K-AKT signaling, thus highlighting a potentially novel therapeutic avenue for the treatment of such metastatic progression in HCC patients.

Abstract
BACKGROUND Esophageal cancer is a common digestive tract tumor that is generally treated with radiotherapy. Poor responses to radiotherapy in most patients generally result in local radiotherapy failure, so it is essential to find new radiosensitizers that can enhance the response of cancer cells to radiotherapy and improve the survival of esophageal cancer patients with radiation resistance. The long non-coding RNA (lncRNA) Rpph1 is highly expressed in human gastric cancer tissues, and represses breast cancer cell proliferation and tumorigenesis. However, the expression of lncRNA Rpph1 in esophageal cancer and its relationship with radio-sensitivity has not been studied.
AIM To explore the value of lncRNA Rpph1 in esophageal cancer and its effect on cancer cell sensitivity to radiotherapy.
METHODS Eighty-three patients with esophageal cancer admitted to Qilu Hospital of Shandong University and 90 healthy participants who received physical examinations were collected as research participants. The expression of Rpph1 was determined by qRT-PCR. siRNA-NC and siRNA-Rpph1 were transfected into esophageal cancer cell lines, and cells without transfection were designated as the blank control group. Cell survival was tested by colony formation assays, and the levels of proteins related to apoptosis and epithelial-mesenchymal transitions were determined by Western blot assays. Cell proliferation was assessed by MTT assays, cell apoptosis by flow cytometry, and cell migration by wound-healing assays. Changes in cell cycle distribution were monitored.
RESULTS Rpph1 was highly expressed in esophageal carcinoma, making it a promising marker for the diagnosis of esophageal cancer. Rpph1 could also be used to distinguish different short-term responses, T stages, N stages, and clinical stages of esophageal cancer patients. The results of 3-year overall survival favored patients with lower Rpph1 expression over patients with higher Rpph1 expression (P < 0.05). In vitro and in vivo experiments showed that silencing Rpph1 expression led to higher sensitivity of esophageal cancer cells to radiotherapy, stronger apoptosis in esophageal cancer cells induced by radiotherapy, higher expression of Bax and caspase-3, and lower expression of Bcl-2 (Bax, caspase-3, and Bcl-2 are apoptosis-related proteins). Additionally, silencing Rpph1 attenuated radiation-induced G2/M phase arrest, and significantly inhibited the expression of proteins involved in cell proliferation, migration, and epithelial-mesenchymal transition regulation in esophageal cancer cells.
CONCLUSION Rpph1 is highly expressed in esophageal cancer. Silencing Rpph1 expression can promote cell apoptosis, inhibit cell proliferation and migration, and increase radio-sensitivity.

Abstract
MicroRNAs (miRNAs) are known to be important in a variety of cancer types. The specific expression and roles of miR-520f-3p in the context of gastric cancer (GC), however, remains unknown. Herein we determined miR-520f-3p expression to be significantly reduced in human GC cells compared to cells of the gastric epithelium, with comparable down-regulation also being evident in gastric cancer tissue samples and the low expression of this miRNA was positively correlated with features of more aggressive large tumor size (p = 0.019), depth of invasion (p = 0.008), and distant metastasis (p = 0.037). We further found that lower levels of miR-520f-3p corresponded with poorer GC patient overall (p = 0.003) and disease-free (p = 0.036) survival. When over-expressed in GC cells, miR-520f-3p was able to impair their growth, proliferation, and survival, instead leading to the induction of apoptosis. We further found that miR-520f-3p was able to bind the SOX9 3'-UTR, thereby negatively regulating its expression in GC cells. Consistent with this model, SOX9 and miR-520f-3p expression were negatively correlated with one another in GC tissues. When SOX9 was upregulated, this was also able to abrogate miR-520f-3p-mediated inactivation of Wnt/β-catenin signaling. Together our findings thus suggest that miR-520f-3p can act to suppress GC progression, at least in part via suppressing SOX9 expression and thus disrupting Wnt/β-catenin signaling. Our results thus highlight potential novel therapeutic targets in GC worthy of future investigation.

Abstract
Artemisinin-based combination therapy is widely used for the treatment of uncomplicated Plasmodium falciparum malaria, and piperaquine (PQ) is one of the important partner drugs. During the biotransformation of PQ, M1 (N-oxidation product), M2 (N-oxidation product), M3 (carboxylic acid product), M4 (N-dealkylation product), and M5 (N-oxidated product of M4) are formed by cytochrome P450 pathways. Despite decades of clinical use, the interactions between PQ and its main metabolites (PQs) with human serum albumin (HSA) have not been reported. In the present study, the binding of PQs with HSA under physiological conditions was investigated systematically through fluorescence, circular dichroism (CD) spectroscopy, and molecular docking methods. The experimental results show that the intrinsic fluorescence quenching of HSA was induced by those compounds resulting from the formation of stable HSA-compound complexes. The main forces involved in the interactions between PQ, M1, and M2 which bind to HSA were hydrogen s and van der Waals forces, while the interactions of M3, M4, and M5 were driven by hydrophobic forces. The main binding sites of the compounds to HSA were also examined by classical fluorescent marker experiments and molecular docking studies. Binding constants (Kb) revealed that the affinities of the PQ, M1, M2, M3, and M4 to HSA were stronger than that of M5. Additionally, the binding rates of PQs with HSA were determined by ultrafiltration methods. Consistent with the binding constant results, the binding rate of M5 was lower than the binding rates of PQ, M1, M2, M3, and M4. Furthermore, PQs binding to HSA led to conformational and structural alterations of HSA, as revealed by multi-spectroscopic studies. In order to investigate one possible mechanism by which PQs inhibit the growth of malaria-causing Plasmodium parasites, 1H NMR spectroscopy was performed to investigate the interaction of the PQs with heme. This study is beneficial to enhance our understanding of the ecotoxicology and environmental behaviors of PQ and its metabolites.

Abstract
Background Healthcare-associated infections (HAIs) are still a major health threats worldwide. Traditional surveillance methods involving manual surveillance by infection control practitioners (ICPs) for data collection processes are laborious, inefficient, and generate data of variable quality. In this study, we sought to evaluate the impact of surveillance and interaction platform system (SIPS) for HAIs surveillance compared to manual survey in tertiary general hospitals. Methods A large multi-center study including 21 tertiary general hospitals and 63 wards were performed to evaluate the impact of electronic SIPS for HAIs. Results We collected 4,098 consecutive patients and found that the hospitals installed with SIPS significantly increased work efficiency of ICPs achieving satisfactory diagnostic performance of HAIs with 0.73 for sensitivity, 0.81 for specificity and 0.81 area under the curve (AUC). However, there were significant heterogeneity own to regions, time of SIPS installation, departments and sample size. Conclusions SIPS significantly improved ICPs efficiency and HAIs monitoring effectiveness, but there were shortcomings such as untimely maintenance and high cost.

Abstract
Objective: To detect potential pathogens including pseudorabies virus in patients with encephalitis of unknown etiology in China and describe novel encephalitic entities. Methods: Patients with clinically suspected infectious encephalitis were enrolled in a multicenter study to identify the pathogens in PUMCH Encephalitis Program.Next-generation sequencing(NGS) of cerebrospinal fluid (CSF) was used in patients with encephalitis of unknown etiology enrolled from 2016 to 2017.The patients diagnosed as PRV encephalitis were studied to describe this novel entity. Results: The four patients(3 male, 1 male, 38-54 years old) had occupational exposure to raw park when working in the production or marketing of pork and at least one got injured during pork-cutting.Two of them were confirmed with NGS of CSF, and anti-PRV antibodies were positive in 3 patients whose serum was available for serological analysis.They all presented with an acute onset of fever, convulsion, loss of consciousness and respiratory failure within 1 to 4 days and rapidly deteriorated even on extensive treatment.All the patients needed ICU admission and 3 needed mechanical ventilation.Two patients also had bilateral retinitis.Neuroimaging revealed symmetric gray matter lesions including limbic system, basal ganglia and midbrain without obvious hemorrhage.Lumbar puncture revealed elevated intracranial pressure and lymphocytic pleocytosis [(6-64)×10(6)/L] of CSF.The patients failed to response to the treatment of acyclovir combined with intravenous immunoglobulin and steroids.Modified Rankin Score was 3, 5, 5 and 6 (died) for the 4 patients respectively on last follow-up. Conclusions: PRV could be a cause of severe encephalitis.The patients with suspected pseudorabies encephalitis (PRE) need to be tested for PRV DNA timely.Severe encephalitis with bilateral involvement of limbic system, basal ganglion, thalamus and midbrain in patient with occupational exposure indicate this emerging infectious encephalitis.

Abstract
Objective:To evaluate the efficacy of SLIT with Dermatophagoides farina drops in monosensitized and polysensitized children with allergic rhinitis and asthma.Method:This retrospective analysis chose 124 cases of allergic rhinitis and asthma with 3 years SLIT treatment. According to skin prick test,they were divided into two groups, monosensitized group (48 patients) and polysensitized group (76 patients). Before SLIT and after SLIT for 1 year, 2 year and 3 years, the TNSS, TRMS of rhinitis and DASS, NASS, TAMS, VAS, PEF, FEV1 of asthma were evaluated. Result:The TNSS, TRMS, DASS, NASS, TAMS, VAS, PEF, FEV1 had continuously improved significantly after SLIT for 1 year, 2 year and 3 years in two groups as compared with baseline (P< 0.05). As compared with after SLIT for 1 year, after SLIT for 2 year the TNSS, TRMS, TAMS, VAS of monosensitized group had obviously decrease (q= 3.76, 5.57, 6.02, 5.62, P< 0.05). As compared with after SLIT for 1 year, similarly, after SLIT for 2 year the TNSS, TRMS, TAMS, VAS of polysensitized group had obviously decrease (q= 5.40, 7.16, 7.19, 7.87, P< 0.05). Before SLIT, TRMS and TAMS of polysensitized group were significantly greater than the monosensitized group (Z=3.16, 2.74, P< 0.05). After SLIT for 1 year, 2 years and 3 years, the all evaluation indicators of two groups were not statistically significant (P> 0.05).Conclusion:Sublingual immunotherapy with Dermatophagoides farina drops in monosensitized and polysensitized children with allergic rhinitis and asthma had similar and significant therapeutic effect.

Abstract
OBJECTIVE This randomized controlled study investigated the feasibility of early ambulation after liver resection and the effect of the amount of activity on postoperative recovery. METHODS A total of 120 patients who underwent liver resection were randomly divided into two groups for the comparative analysis of the following factors: amount of activity, pain control, sleeping state, perioperative gastrointestinal function recovery, incidence of complications and postoperative hospital stay. RESULTS Compared with the control group, patients undergoing liver resection performing early postoperative ambulation had faster gastrointestinal function recovery (First exhaust time 2.2 ± 1.4 vs. 3.3 ± 2.3 p < 0.01; First flatus time 2.3 ± 1.7 vs. 3.1 ± 2.5 p = 0.04) and shorter postoperative hospital stays (6.6 ± 2.3 vs. 7.7 ± 2.1 p = 0.01), with statistically significant differences. There was no significant difference in the incidence of postoperative complications between the two groups (p > 0.05). CONCLUSION Early ambulation after liver resection is safe and feasible. It can reduce the patient's pain and economic burden, increase the patient's comfort, reduce the nursing workload, achieve rapid recovery, and improve patient satisfaction.

Abstract
In this paper, a SOI (silicon-on-insulator)-based piezoresistive fluid flow sensor is presented; the presented flow sensor mainly consists of a nylon sensing head, stainless steel cantilever beam, SOI sensor chip, printed circuit board, half-cylinder gasket, and stainless steel shell. The working principle of the sensor and some detailed contrastive analysis about the sensor structure were introduced since the nylon sensing head and stainless steel cantilever beam have distinct influence on the sensor performance; the structure of nylon sensing head and stainless steel cantilever beam is also discussed. The SOI sensor chip was fabricated using micro-electromechanical systems technologies, such as reactive ion etching and low pressure chemical vapor deposition. The designed fluid sensor was packaged and tested; a calibration installation system was purposely designed for the sensor experiment. The testing results indicated that the output voltage of the sensor is proportional to the square of the fluid flow velocity, which is coincident with the theoretical derivation. The tested sensitivity of the sensor is 3.91 × 10-4 V ms2/kg.

Abstract
Rapamycin is known to extend lifespan. We conducted a randomized placebo-controlled study of enteric rapamycin-treatment to evaluate its effect on physical function in old low capacity runner (LCR) rats, a rat model selected from diverse genetic background for low intrinsic aerobic exercise capacity without genomic manipulation and characterized by increased complex disease risks and aging phenotypes. The study was performed in 12 male and 16 female LCR rats aged 16-22 months at baseline. The treatment group was fed with rapamycin-containing diet pellets at approximately 2.24mg/kg body weight per day and the placebo group with the same diet without rapamycin for six months. Observation was extended for additional 2 months. Physical function measurements include grip strength measured as maximum tensile force using a rat grip strength meter and maximum running distance (MRD) using rat physical treadmill test. The results showed that rapamycin improved grip strength by 13% (p=.036) and 60% (p<.001) from its baseline in female and male rats, respectively. Rapamycin attenuated MRD decline by 66% (p<.001) and 46% (p=.319) in females and males, respectively. These findings provide initial evidence for beneficial effect of rapamycin on physical functioning in an aging rat model of high disease risks with significant implication in humans.

Abstract
Chicken Toll-like receptor 15 (ChTLR15) has been shown to participate in immune activation in response to various pathogens and in the innate defence against infection. Two genetically distinct Chinese breeds of chicken (Qinyuan Partridge and Baier breeds) were used to study the correlation between ChTLR15 single nucleotide polymorphisms and the natural infection status of salmonella in hens, and also to examine genetic and sex-specific effects on ChTLR15 mRNA expression in heterophils and spleen during acute infection with Salmonella enterica serovar Enteritidis (SE) from 1 to 10 days after experimental infection. Three single-nucleotide polymorphisms (G168A, C726T and A1166G) in a single exon of ChTLR15 were identified in the two breeds, but only C726T showed a significant association with salmonella infection. Compared with layer-type Baier chicks, meat-type Qingyuan chicks showed a higher tolerance for capture stress and (SE) infection, as measured, respectively, by the modified body weight of chicks in the control group and in the infection group. Meanwhile, ChTLR15 down-regulation in heterophils and up-regulation in spleen were involved in the response to pathogenic SE colonization during the acute infection period. These significant genetic effects in females led to greater differences in both innate and adaptive immune responses than those exhibited in males. These results suggest that genetics, time and gender play important roles in the modulation of ChTLR15 mRNA level elicited by the SE-mediated immune response differentially in the two genetically distinct breeds, with a focus on sexual dimorphism.

Abstract
Many cases of liver carcinoma miss the opportunity of surgical treatment because of hidden onset and delayed diagnosis. In recent years, interventional treatment has gradually become a non-surgical method for treating liver carcinoma. To discuss the effects of oxaliplatin in combination with epirubicin in the treatment and its influence on prognosis, this study randomly selected 218 advanced primary liver carcinoma patients from Binzhou Peoples Hospital, Binzhou, China and divided them into a control group (n=109) and an observation group (n=109). Patients in both groups were given interventional treatment. Patients in the control group were perfused with oxaliplatin, while patients in the observation group were perfused with oxaliplatin and epirubicin. The effectsat 6-month and 12-month survival rates were compared between the two groups. The results demonstrated that the overall effective rate and clinical benefit rate of the observation group were much higher than those of the control group (30.3% vs 11.9%; 79.8%; vs 44.3%) (P less than 0.05). The serum Alpha Fetal Protein (AFP) and Carcino Embryonie Antigen (CEA) levels of the observation group were much lower than those of the control group; the Karnofsky performance score of the observation group was much lower than that of the control group; the two differences had statistical significance (P less than 0.05). The 6-month survival rate of the observation group was 91.67%, higher than that of the control group (86.11%) (P>0.05). The 12-month survival rate of the observation group was 83.33%, much higher than that of the control group (61.11%) (P less than 0.05). The difference of the incidence of adverse reactions between the two groups had no statistical significance (P>0.05). Thus, it can be concluded that oxaliplatin in combination with epirubicin can improve survival quality, extend survival time, and decrease the serum AFP and CEA levels in the treatment of primary liver carcinoma, with definite effects but without aggravating toxic and side effects. Therefore, the therapy has important clinical value.

Abstract
OBJECTIVE The aim of this study was to prospectively investigate the incidence of ventilator associated events (VAEs) in intensive care units (ICUs) among adult patients, and to evaluate the correlation between VAEs and ventilator associated pneumonia (VAP). METHODS A prospective 3-month cohort study (January 2015 to March 2015) was carried out. VAEs were divided into three groups: with ventilator-associated condition (VAC), with infection related ventilator-associated complication (IVAC) and with possible VAP (PVAP). Sensitivity and specificity of VAEs were evaluated and compared to the traditional VAP. Kappa test was applied to judge the consistency of VAC and VAP. RESULTS During Jan. 2015 and Mar. 2015, 1 014 patients were admitted to 8 ICUs, with 7 977 patients per day. In total, 197 patients used the mechanical ventilation installation, with, a total number of 3 152 ventilator-days. Finally, 1 214 ventilation days in the VAC group and 1 938 ventilation days in the non-VAC group) that were available for final analysis. 46 VAC cases were identified including 22 classified as IVAC (14.59 and 6.98 per 1 000 ventilation days, respectively). Length of ICU stay and duration on mechanical ventilation for VAC patients were both significantly longer than those for non-VAC patients (P<0.05). Sensitivity and specificity of the VAC criteria for the detection of VAP were 36.92% and 83.33%, respectively. CONCLUSION The VAEs surveillance paradigms could be applied to monitor patients on the use of mechanical ventilation installation. However, sensitivity and specificity of VAC were under pool for the diagnosis of VAP. However, automatically surveillance programs was relied on the improvement of auto-information systems.

Abstract
OBJECTIVE To investigate the structural changes of gray matter in women with primary dysmenorrhea (PDM) and discuss the potential relationships between the changes and etiology of the disease. METHODS We used an optimized voxel-based morphometry (VBM) approach to compare total and regional volumetric changes of gray matter in 20 primary dysmenorrhea patients with 20 healthy age and menstrual cycle matched controls.All subjects were patients from the outpatient department of Tongji Hospital in 2015. RESULTS Abnormal volumetric decreases of gray matter were found in the left and right parahippocampus, the left and right middle temporal gyrus, the left and right superior parietal lobule, the left postcentral cortex, the left and right inferior parietal lobule, which involved in pain transmission, pain modulation and somatic sensation. CONCLUSION Abnormal gray matter volume changes are present in some encephalic regions of PDM patients.The functions of these regions are associated with pain modulation and somatic sensation, which suggests the changes are related with PDM.

Abstract
Based on first principles calculations, we systematically investigated the structural, electronic and ferroelectric properties of Pt-BaTiO3-Pt ferroelectric tunnel junctions (FTJs) with CO adsorbed on the surface of the top electrode. Changes of electrode/barrier thickness and different adsorption sites were considered. We found that although the CO molecule is not directly adsorbed on the surface of the ferroelectric thin film (FTF), the local properties of the BaTiO3 FTFs were still significantly changed by CO adsorptions, e.g. the change of polarization bistability. Furthermore, by simulating isolated geometry, we found that the orientation of polarization induced by CO adsorptions exhibited sensitive dependence on the thickness of the adsorbed electrode. The adsorption energy was found to change with the change of both the thickness of the electrodes and the polarization orientation in the barrier, which provides a modifiable effect by virtue of the surface ambient chemicals controlling the bulk ferroelectric properties. An electronic structure analysis reveals that the work function of the adsorbed electrode is altered by the adsorption, and the effect can be reversed as the electrode thickness changes. Our findings should provide a new method to tailor the magnitude and bistability of polarization in ferroelectric thin films (FTF) as well as the top electrode surface reactivity in FTJs, which has a significant prospect of application in FTJ-based nanoscale multifunctional devices.

Abstract
In clinical practice, patients after abdominal surgery usually suffer from abdominal distention. Abdominal distention causes discomfort and hinders post-surgery recovery. To alleviate abdominal distention, clinical physicians generally resort to medications or employ means such as placing gastrointestinal decompression or anal tubes, albeit with limited effect. Fast-track post-surgery rehabilitation advocates early post-surgery exercises for the prevention or alleviation of abdominal distension, but the approach also has limitations. In recent years, nursing practitioners have been researching novel nursing approaches based on traditional Chinese medicine. Some of these approaches have been demonstrated to help correct postoperative gastrointestinal function disorders, alleviate postoperative abdominal distention, enhance patient comfort and reduce the risk of post-surgery complications. This article focuses on reviewing nursing approaches based on traditional Chinese medicine for the alleviation of abdominal distention in patients after abdominal surgery. The efficacy of different nursing approaches will also be discussed.

Abstract
1. Salmonella enteritidis (SE) is reported as the most common food-borne pathogen transmitted through poultry products. The natural resistance-associated macrophage protein 1 (NRAMP1) is a candidate gene associated with SE-mediated immune response and is related to the phagocytosis of SE. In this study, the classical single-nucleotide polymorphism (SNP) G2357A in exon 8 of the NRAMP1 gene was detected. The expression of NRAMP1 mRNA was first investigated in heterophil granulocytes and spleen in chicks from two different Chinese native breeds at 1, 3 and 10 d post-infection. In addition, the association with the effect of SE challenge was identified. 2. The G2357A SNP showed no significant association with Salmonella natural infection in birds from two different Chinese native breeds. 3. The upregulation of NRAMP1 mRNA in heterophils and spleen was involved in the response to pathogenic SE colonisation during the acute infection period in chicks. The results suggest that genetics, age, gender and interactions among these factors play important roles in the modulation of NRAMP1 mRNA expression and copy number by SE-mediated immune response in different Chinese chickens. 4. In conclusion, the enhancement of host immunity mediated by the upregulation of NRAMP1 mRNA in heterophil granulocytes and spleen might be more obvious and earlier in the chicks resistant to infections with SE than in susceptible chicks.

Abstract
UNLABELLED With a continuously increasing aging population and the improvement of living standards, large demands of biomaterials are expected for a long time to come. Further development of novel biomaterials, that are much safer and of much higher quality, in terms of both biomedical and mechanical properties, are therefore of great interest for both the research scientists and clinical surgeons. Compared with the conventional crystalline metallic counterparts, bulk metallic glasses have unique amorphous structures, and thus exhibit higher strength, lower Young's modulus, improved wear resistance, good fatigue endurance, and excellent corrosion resistance. For this purpose, bulk metallic glasses (BMGs) have recently attracted much attention for biomedical applications. This review discusses and summarizes the recent developments and advances of bulk metallic glasses, including Ti-based, Zr-based, Fe-based, Mg-based, Zn-based, Ca-based and Sr-based alloying systems for biomedical applications. Future research directions will move towards overcoming the brittleness, increasing the glass forming ability (GFA) thus obtaining corresponding bulk metallic glasses with larger sizes, removing/reducing toxic elements, and surface modifications. STATEMENT OF SIGNIFICANCE Bulk metallic glasses (BMGs), also known as amorphous alloys or liquid metals, are relative newcomers in the field of biomaterials. They have gained increasing attention during the past decades, as they exhibit an excellent combination of properties and processing capabilities desired for versatile biomedical implant applications. The present work reviewed the recent developments and advances of biomedical BMGs, including Ti-based, Zr-based, Fe-based, Mg-based, Zn-based, Ca-based and Sr-based BMG alloying systems. Besides, the critical analysis and in-depth discussion on the current status, challenge and future development of biomedical BMGs are included. The possible solution to the BMG size limitation, the brittleness of BMGs has been proposed.

Abstract
Mutations in the BRCA1/2 genes are associated with an increased risk of breast cancer, but no large-scale research have examined the BRCA1/2 mutations in Chinese Kazakh women. We evaluated the frequency and distributions of BRCA1 and BRCA2 gene mutations in Kazakh sporadic breast cancer patients and healthy women in China. The association between the clinical-pathologic features of Kazakh breast cancer patients and BRCA1/2 mutations were also investigated. Two unclassified variants (T539M and T1915M) and 16 polymorphisms were detected in this study, 4 of which (G356A, His743, Asn991Asp, Val1269) were detected more frequently in breast cancer patients than in healthy controls. We observed a higher prevalence of BRCA1/2 common sequence alterations and a large number of Kazakh women carrying multiple co-existing BRCA1/2 mutations. The prevalence of BRCA1 mutations was similar to that of BRCA2 mutations. Although no significant differences were observed, BRCA1/2 carriers were generally younger at diagnosis of wild-type breast cancer patients. BRCA1-associated Kazakh sporadic breast cancers present with high tumor grade, early stage, negative lymph node status, absence of estrogen receptor expression and progesterone-positive status. Estrogen receptor expression was the only predominant histological type in BRCA2 carriers. In this study, we determined the BRCA1 and BRCA2 gene mutation status and determined the association with clinical-pathologic characteristics in a Chinese Kazakh population. Larger population-based screening studies screening the entire coding region of BRCA1/2 are required to evaluate the breast cancer risk induced by the sequence alterations detected in this study.

Abstract
The fat mass- and obesity-associated gene (FTO) is involved in energy metabolism, but little is known about the chicken FTO gene. The objective of the current study was to detect chicken FTO expression patterns in the hypothalamus, liver, and skeletal muscle during development, and analyze the effects of age and breed on FTO expression. Real-time quantitative polymerase chain reaction results revealed that chicken FTO mRNA was expressed in all of the tissues tested. Chicken FTO exhibited tissue- and breed-specific patterns in the recessive White Plymouth Rock chicken and the Qingyuan partridge chicken. The highest FTO expression level was in the hypothalami of 1-week-old chicks. FTO mRNA was expressed more in the breast muscles and livers of recessive White Plymouth Rock chickens than those of Qingyuan partridge chickens at 1 and 8 weeks of age. These results indicate that FTO probably plays a significant role in energy metabolism at 1 week old, when chicks have undergone metabolic adaptations from yolk dependence to the utilization of exogenous feed.

Abstract
Biodegradable metals have attracted considerable attentions in recent years. Besides the early launched biodegradable Mg and Fe metals, Zn, an essential element with osteogenic potential of human body, is regarded and studied as a new kind of potential biodegradable metal quite recently. Unfortunately, pure Zn is soft, brittle and has low mechanical strength in the practice, which needs further improvement in order to meet the clinical requirements. On the other hand, the widely used industrial Zn-based alloys usually contain biotoxic elements (for instance, ZA series contain toxic Al elements up to 40 wt.%), which subsequently bring up biosafety concerns. In the present work, novel Zn-1X binary alloys, with the addition of nutrition elements Mg, Ca and Sr were designed (cast, rolled and extruded Zn-1Mg, Zn-1Ca and Zn-1Sr). Their microstructure and mechanical property, degradation and in vitro and in vivo biocompatibility were studied systematically. The results demonstrated that the Zn-1X (Mg, Ca and Sr) alloys have profoundly modified the mechanical properties and biocompatibility of pure Zn. Zn-1X (Mg, Ca and Sr) alloys showed great potential for use in a new generation of biodegradable implants, opening up a new avenue in the area of biodegradable metals.

Abstract
AIM: To explore the significance of serum sCD25 level in the diagnosis of hepatocellular carcinoma (HCC).
METHODS: A total of 160 subjects, including 40 patients with HCC, 40 patients with liver cirrhosis, 40 patients with chronic hepatitis B, and 40 healthy controls, were measured for serum sCD25 levels by enzyme-linked immuno sorbent assay (ELISA).
RESULTS: Serum sCD25 level in the HCC group (mean, 9641.23 pg/mL) was significantly higher than those in the cirrhosis group, chronic hepatitis B group and healthy control group (P < 0.05). Serum sCD25 level demonstrated a better sensitivity than alpha fetal protein (AFP) in the diagnosis of HCC.
CONCLUSION: Serum sCD25 level is effective in the detection of early HCC, and it may serve as a novel predictive marker of HCC to distinguish advanced cirrhosis from early HCC.

Abstract
The characteristics of scattering due to interface roughness are usually described by the backscattering matrix for reverberation modeling. The backscattering matrix based on the Bass perturbation theory has significant differences from that based on the empirical scattering rule (Lambert's rule), especially at low grazing angles. In a waveguide environment with a point source, it is very difficult to extract the quantitative characteristics of the backscattering matrix at low grazing angles from the experimental data because of the difficulties in acquiring low-grazing-angle scattering data and separating the scattering data between different modes (grazing angles). In contrast, the use of single-mode excitations as sources in shallow-water waveguides enables acquisition of good quality low-grazing-angle scattering data. In this paper, the characteristics of the backscattering matrix were obtained from different single-mode reverberation experiments in shallow-water. The experiments were carried out at different sites during different seasons off the coasts of China. Model-data comparisons were made and the results showed that at low grazing angles (2°-5°), the backscattering matrices based on the Bass perturbation theory were in good agreement with the experimental data, but the backscattering matrices based on Lambert's rule were not.

Abstract
Growth hormone (GH) has diverse functions in animals, together with other hormones from the somatotropic axis. Here, chicken GH (cGH) was investigated in recessive white chickens and Qingyuan partridge chickens as a candidate gene affecting egg production traits. Chicken egg production traits were studied in association with 4 selected single nucleotide polymorphisms (T185G, G662A, T3094C, and C3199T). Genotyping was performed by the polymerase chain reaction-ligase detection reaction method. T185G was significantly associated with the egg production traits of body weight at first egg (BW), egg weight at first egg (EW), and the total egg production of 300-day old birds (EN 300). T3094C was also significantly associated with certain egg production traits; however, it affected the 2 breeds differently. Haplotypes of the 4 single nucleotide polymorphisms were also significantly associated with egg production traits of chicken age at first egg laying, BW, EW, and EN 300. H1H6 was the most advantageous diplotype for egg production. We putatively concluded that polymorphisms in the cGH gene and its haplotypes could be used as potential molecular markers for egg production traits to enhance the breeding programs of indigenous chickens.

Abstract
Chinese black-bone chickens are valued for the medicinal properties of their meat in traditional Chinese medicine. We investigated the genetic diversity and systematic evolution of Chinese black-bone chicken breeds. We sequenced the DNA of 520 bp of the mitochondrial cyt b gene of nine Chinese black-bone chicken breeds, including Silky chicken, Jinhu black-bone chicken, Jiangshan black-bone chicken, Yugan black-bone chicken, Wumeng black-bone chicken, Muchuan black-bone chicken, Xingwen black-bone chicken, Dehua black-bone chicken, and Yanjin black-bone chicken. We found 13 haplotypes. Haplotype and nucleotide diversity of the nine black-bone chicken breeds ranged from 0 to 0.78571 and 0.00081 to 0.00399, respectively. Genetic diversity was the richest in Jinhu black-bone chickens and the lowest in Yanjin black-bone chickens. Analysis of phylogenetic trees for all birds constructed based on hyplotypes indicated that the maternal origin of black-bone chickens is predominantly from three subspecies of red jungle fowl. These results provide basic data useful for protection of black-bone chickens and help determine the origin of domestic chickens.

Abstract
The experiment was designed to study the mechanism of increasing efficiency of Ligustrum lucidum steamed with wine. Rats in vivo with gastrointestinal perfusion model were used. The contents of salidroside and specnuezhenide in the fluid of gastrointestinal perfusion of rats were measured by HPLC at different time points after dosing. Then the K(a) and absorption percentage were calculated. Specnuezhenide could be detected in the fluid of gastrointestinal perfusion of specnuezhenide. The K(a) of the specnuezhenide and salidroside in the fetal intestines are 0.055 3 and 0.144 2 h(-1) respectively and the total absorptivity are 24.46% and 60.14% respectively after 4 hours. The K(a) in the stomach are 5.70 and 8.26 h(-1) respectively and the total absorptivity are 34.21% and 47.23% respectively after 4 hours. The experiment proved that specnuezhenide can be metabolized into salidroside which is more beneficial for gastrointestinal absorption. The experiment proved that specnuezhenide can be metabolized into salidroside both in the rat's stomach and the fetal intestine and compared with the specnuezhenide salidroside is more conducive to gastrointestinal absorption. The results suggested that the increasing efficiency on liver and kidney of L. lucidum steamed with wine has business with the fact that Specnuezhe nide is more conducive to the body after it is changed into salidroside.

Abstract
The peroxisome proliferators-activated receptor-γ coactivator-1α (PGC-1α) is a candidate gene for meat quality traits because of its prominent role in muscle fiber type switching and determination. We investigated the effects of the PGC-1α gene on chicken skeletal muscle fiber type switching and on other meat quality traits. Single nucleotide polymorphisms were detected by PCR-SSCP and DNA sequencing, and then genotyping was performed by PCR-ligation detection reaction methods. Skeletal muscle fiber types, intramuscular fat content, shear forces, and water loss rate of the gastrocnemius lateralis muscle were measured in Qingyuan Partridge chickens and Recessive White chickens. Four SNPs, C171T in exon2, C384T in exon3, G646A in exon5, and A948G in exon8 were detected. Marker-trait association analysis indicated that G646A polymorphism was associated with skeletal myofiber type and that H1 (CCAA) was the most advantageous haplotype for skeletal myofiber type. We concluded that polymorphisms of the PGC-1α gene and their haplotypes are associated with chicken skeletal myofiber type traits.

Abstract
Nitrous oxide (N2O) and methane (CH4) are two important greenhouse gases (GHG) emitted from biological nutrient removal (BNR) processes in municipal wastewater treatment plants (WWTP). In this study, three typical biological wastewater treatment processes were studied in WWTP of Northern China: pre-anaerobic carrousel oxidation ditch (A+OD) process, pre-anoxic anaerobic-anoxic-oxic (A-A/ A/O) process and reverse anaerobic-anoxic-oxic (r-A/ A/O) process. The N2O and CH4 emissions from these three different processes were measured in every processing unit of each WWTP. Results showed that N2O and CH4 were mainly discharged during the nitrification/denitrification process and the anaerobic/anoxic treatment process, respectively and the amounts of their formation and release were significantly influenced by different BNR processes implemented in these WWTP. The N2O conversion ratio of r-A/ A/O process was the lowest among the three WWTP, which were 10.9% and 18.6% lower than that of A-A/A/O process and A+OD process, respectively. Similarly, the CH4 conversion ratio of r-A/ A/O process was the lowest among the three WWTP, which were 89. I% and 80.8% lower than that of A-A/ A/O process and A+OD process, respectively. The factors influencing N2O and CH4 formation and emission in the three WWTP were investigated to explain the difference between these processes. The nitrite concentration and oxidation-reduction potential (ORP) value were found to be the dominant influencing factors affecting N2O and CH4 production, respectively. The flow-based emission factors of N2O and CH4 of the WWTP were figured out for better quantification of GHG emissions and further technical assessments of mitigation options.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shaoyao-Gancao Decoction (SGD), a well-known traditional Chinese medicine prescription, is a combination of Radix Paeoniae Alba (Paeonia lactiflora Pall, root) and Glycyrrhizae uralensis (Glycyrrhiza uralensis Fisch., root and rhizome, honeyed) for spasmolysis and emergency pain relief. Paeoniflorin (PF) and glycyrrhetinic acid (GA) are two typical active components of SGD for pain relief. AIM OF THE STUDY To study comparative pharmacokinetics of ten bioactive compounds in SGDs with two different combinations of RP and GU, and therefore to investigate the herb-herb interaction mechanisms of Shaoyao-Gancao Decoction for better spasmolysis and emergency pain relief in rats. MATERIALS AND METHODS Herbal IR macro-fingerprinting was implemented to provide the full chemical fingerprints of RP, GU and SGD decoctions and to investigate the variation rule of the full chemical profile of SGDs with various combinations of RP and GU. A specifically developed HPLC-MS/MS assay coupled with protein precipitation method was employed to determine the plasma concentrations of the ten analytes. Male Wistar rats were orally administered with SGD1 (RP:GU, 1:1 (w/w)) and SGD2 ((RP:GU, 4:1 (w/w)) equivalent to 9.5 g/kg body weight of GU. RESULTS Full chemical fingerprints of RP, GU and SGDs with various combinations of RP and GU were provided in the form of IR macro-fingerprints. Except for liquiritin, there were statistically significant differences (p<0.05 or p<0.01) of these analytes between SGD1 and SGD2 in in vivo pharmacokinetic study. Compared with the results when oral administrated with SGD1, six glycosides (PF, albiflorin, oxypaeoniflorin, isoliquiritin, ononin, and glycyrrhizin) exhibited higher systematic exposure levels (AUC0-t) and slower elimination rates (CL) whereas two glycones (GA and isoliquiritigenin) were the reverse when administrated with SGD2. CONCLUSIONS Increasing the amount of RP attenuated the inhibitory effect of GA via competing being consumed by intestinal bacteria (or β-glucosidase) to reduce the conversion amount of glycyrrhizin to GA and subsequently to afford significantly higher bioavailability and longer efficacy of PF, glycyrrhizin, albiflorin, oxypaeoniflorin, isoliquiritin, and ononin, leading to better spasmolysis and emergency pain relief.

Abstract
OBJECTIVES To investigate variability in the upper airway of subjects with different anteroposterior skeletal patterns by evaluating the volume and the most constricted cross-sectional area of the pharyngeal airway and defining correlations between the different variables. MATERIAL AND METHODS The study sample consisted of 60 patients (29 boys, 31 girls) divided into three groups: Class I (1 ≤ ANB ≤ 3), Class II (ANB>3), and Class III (ANB<1), to evaluate how the jaw relationship affects the airway volume and the most constricted cross-sectional area (Min-CSA). Differences between groups were determined using the Tukey-Kramer test. Correlations between variables were tested using Pearson's correlation coefficient. RESULTS The volume and the Min-CSA of the pharyngeal airway (PA) were significantly related to anteroposterior skeletal patterns (p < 0.05). The nasopharyngeal airway (NA) volume of Class I and Class III subjects was significantly larger than that of Class II subjects (p < 0.05). The Min-CSA and the length of PA were significantly related to the volume of PA (p < 0.05). The site and the size of the Min-CSA varied among the three groups. CONCLUSIONS The volume and the most constricted cross-sectional area of the airway varied with different anteroposterior skeletal patterns. The NA volume of Class I and Class III subjects was significantly larger than that of patients with a Class II skeletal pattern.

Abstract
This experiment was conducted to study the digestibility of uncommon feedstuffs for geese. Thirty Taihu ganders were selected and divided into 5 groups (n = 6), and one group was allocated as the control. Taihu ganders in the 4 treated groups were force-fed with a weight of different uncommon feedstuffs after 24 h of fasting, and the control group was kept in fasting with no force feeding. All excretion of each gander was collected on a plate for 24 h after force feeding. There was a 12-d recovery period between treatments. In this study, we measured the ME and analyzed neutral detergent fiber, acid detergent fiber, and hemicellulose of brewers grains, distillers grains, empty-grain rice, ryegrass powder, rice husk, corn stalk, rice straw, wheat straw, wheat husk, mushroom bran, and peanut vine. The TME values were 9.29, 8.67, 8.97, 5.89, 3.85, 3.10, 3.32, 3.02, 5.29, 2.48, and 3.15 MJ/kg, respectively. The digestibility of neutral detergent fiber for the feedstuffs ranged from 6.14 to 45.0%, the digestibility of acid detergent fiber ranged from 4.52 to 32.6%, and the digestibility of hemicellulose ranged from 18.5 to 61.6%. The best TME quadratic prediction equation was TME = 12.2 - 0.232CF, where CF is crude fiber. These results suggest that geese were able to use uncommon feedstuffs with high digestibility, and there was a significant negative correlation between energy digestibility and CF content. The ME values tested in this experiment can provide a foundation for preparation and adjustment of feed formulation for reasonable use of uncommon feedstuffs for geese.

Abstract
In this study, a high glass forming system, Ti41.5Zr2.5Hf5Cu37.5Ni7.5Si1Sn5 (TZHCNSS) bulk metallic glass (BMG), is studied in terms of microstructure, surface analysis, mechanical properties, corrosion resistance, in vitro cytotoxicity and in vivo biocompatibility. It is found that the as-prepared TZHCNSS samples are fully amorphous by XRD and TEM observations, as well as DSC curve. Comparing with pure Ti, TZHCNSS BMG shows superior mechanical properties with higher hardness and better wear resistance. Due to the oxide film formed on its surface, TZHCNSS BMG shows great corrosion resistance close to pure Ti in electrochemical measurements. The pitting corrosion potential in artificial saliva solution is much higher than that in SBF solution. The indirect and direct cytotoxicity results show that TZHCNSS extracts had obvious low cell viability on both L929 and NIH3T3 cells. However, the in vivo testing results proved that TZHCNSS BMG could integrate with bone tissue, showing excellent osseointegration.
