Abstract
AIM This study aimed to reveal the unique microenvironment of peri-implantitis through single-cell analysis. MATERIALS AND METHODS Herein, we performed single-cell RNA sequencing (scRNA-seq) of biopsies from patients with peri-implantitis (PI) and compared the results with healthy individuals (H) and patients with periodontitis (PD). RESULTS Decreased numbers of stromal cells and increased immune cells were found in the PI group, which implies a severe inflammatory infiltration. The fibroblasts were found to be heterogeneous and the specific pro-inflammatory CXCL13+ sub-cluster was more represented in the PI group, in contrast to the PD and H groups. Furthermore, more neutrophil infiltration was detected in the PI group than in the PD group, and cell-cell communication and ligand-receptor pairs revealed most neutrophils were recruited by CXCL13+ fibroblasts through CXCL8/CXCL6-CXCR2/CXCR1. Notably, our study demonstrated that the unique microenvironment of the PI group promoted the differentiation of monocyte/macrophage lineage cells into osteoclasts, which might explain the faster and more severe bone resorption in the progression of PI than PD. CONCLUSIONS Collectively, this study suggests a unique immune microenvironment of PI, which may explain the differences between PI and PD in the clinic. These outcomes will aid in finding new specific and effective treatments for PI.

Abstract
A BaTiO3/SrCoO2.5 (BTO/SCO) bilayer and a BTO single film were prepared by radio frequency magnetron sputtering on La0.7Sr0.3MnO3 (LSMO) buffered SrTiO3 (001) substrates. Interestingly, compared with reported BTO-based films, the BTO/SCO/LSMO heterostructure has a maximum ON/OFF current ratio of ∼945. More interestingly, compared with the BTO single layer, a larger Pr (∼18.4 μC cm-2) and larger dielectric tunability (∼71.9%) were achieved in the BTO/SCO bilayer. The improved performance may be attributed to the large tetragonality and improved oxygen vacancy concentrations in the BTO/SCO/LSMO heterostructure. Furthermore, our BTO/SCO/LSMO stacks exhibit potential for flexible electronic informational devices.

Abstract
Objective: To analyze the flow field characteristics of the upper airway in patients with different adenoid hypertrophy using computational fluid dynamics (CFD). Methods: From November 2020 to November 2021, the cone-beam CT (CBCT) data of 4 patients [2 males and 2 females,age range 5-7 years, mean (6.0±1.2) years] with adenoid hypertrophy who were hospitalized in the Department of Orthodontics and the Department of Otolaryngology at Hebei Eye Hospital were selected. The degree of adenoid hypertrophy in the 4 patients was divided into normal S1 (A/N<0.6), mild hypertrophy S2 (0.6≤A/N<0.7), moderate hypertrophy S3 (0.7≤A/N<0.9) and severe hypertrophy S4 (A/N≥0.9) according to the ratio of adenoid thickness to the width of nasopharyngeal cavity (A/N). The CFD model of the upper airway was established using ANSYS 2019 R1 software, and the internal flow field of the CFD model was numerically simulated. Eight sections were selected as observation and measurement planes for flow field information. Relevant flow field information includes airflow distribution, velocity variation, and pressure variation. Results: In the S1 model, the maximum pressure difference occurred in the 4th and 5th observation planes (ΔP=27.98). The lowest pressures and the maximum flow rates of S2 and S3 were located in the 6th observation plane. The airflow in S1 and S2 models completely passed through the nasal cavity. In the S3 model, the mouth-to-nasal airflow ratio was close to 2∶1. In S4 model, the airflow completely passed through the mouth; in the S1 and S2 models, hard palates were subjected to a downward positive pressure with a pressure difference of 38.34 and 23.31 Pa, respectively. The hard palates in S3 and S4 models were subjected to a downward negative pressure with a pressure difference of -2.95 and -21.81 Pa, respectively. Conclusions: The CFD model can objectively and quantitatively describe the upper airway airflow field information in patients with adenoid hypertrophy. With the increasing degree of adenoid hypertrophy, the nasal ventilation volume gradually decreased, whereas the oral space ventilation volume gradually increased, and the pressure difference between the upper and lower surfaces of the palate gradually decreased until the pressure became negative.

Abstract
Objective: To explore the effects of mothers' exposure to polycyclic aromatic hydrocarbons during pregnancy on their children's neurobehavioral development. Methods: In November 2009 to April 2010, a total of 221 pairs of mother-newborn pairs were recruited from two cooperative hospitals in Taiyuan, and their children were followed up at age two. High performance liquid chromatography was used to determine the level of BPDE-DNA in cord blood leukocytes. The Neonatal behavioral neurological assessment (NBNA) was used to assess the neurodevelopment of newborns, and the Gesell Development Scale was used to measure neurodevelopmental indexes of 2-year-old children. NBNA includes behavior, active and passive tone, primitive reflexes and general assessment, with a total score of 40 points. The Gesell Developmental Schedules consisted of four sub-scales: motor development, adaptive behavior development, language development and personal-social behavior development. We used mean and standard deviation to describe continuous variables with normal distribution, median (interquartile range) to describe continuous variables with skewed distribution, and frequency and proportion to describe categorical variables. Restricted cubic spline models were applied to assess the dose-response relationships between maternal prenatal polycyclic aromatic hydrocarbons exposure and children's neurobehavioral development at two years old. Generalized linear models were applied to evaluate the effect of exposure to maternal prenatal polycyclic aromatic hydrocarbons exposure on children's neurobehavioral development at 0 and two years old. Results: The NBNA score was 38.0±0.8, and the scores of 2-year-old children's motor, adaptive, language and personal-social were 111.6±15.0, 110.5±14.6, 108.8±17.2 and 111.7±14.5, respectively. After adjusting for confounding factors, there is no dose-response association between the cord blood BPDE of pregnant women and neonatal NBNA scores, but there were dose-response associations between BPDE and scores of 2-year-old children's motor, adaptive, language and personal-social. A unit increase in cord blood ln (BPDE-DNA), the score of motor, adaptive, language and personal-social of 2-year-old children decreased on average by 4.54、6.29、8.41 and 7.02 points. Conclusion: Maternal exposure to polycyclic aromatic hydrocarbons during pregnancy is associated with decreased children's neurobehavioral development at two years old.

Abstract
The role of mitochondrial ROS in signalling muscle adaptations to exercise training has not been explored in detail. We investigated the effect of supplementation with the mitochondria-targeted antioxidant MitoQ on a) the skeletal muscle mitochondrial and antioxidant gene transcriptional response to acute high-intensity exercise and b) skeletal muscle mitochondrial content and function following exercise training. In a randomised, double-blind, placebo-controlled, parallel design study, 23 untrained men (age: 44 ± 7 years, VO2peak: 39.6 ± 7.9 ml/kg/min) were randomised to receive either MitoQ (20 mg/d) or a placebo for 10 days before completing a bout of high-intensity interval exercise (cycle ergometer, 10 × 60 s at VO2peak workload with 75 s rest). Blood samples and vastus lateralis muscle biopsies were collected before exercise and immediately and 3 h after exercise. Participants then completed high-intensity interval training (HIIT; 3 sessions per week for 3 weeks) and another blood sample and muscle biopsy were collected. There was no effect of acute exercise or MitoQ on systemic (plasma protein carbonyls and reduced glutathione) or skeletal muscle (mtDNA damage and 4-HNE) oxidative stress biomarkers. Acute exercise-induced increases in skeletal muscle peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1-α) mRNA expression were augmented in the MitoQ group. Despite this, training-induced increases in skeletal muscle mitochondrial content were similar between groups. HIIT-induced increases in VO2peak and 20 km time trial performance were also similar between groups while training-induced increases in peak power achieved during the VO2peak test were augmented in the MitoQ group. These data suggest that training-induced increases in peak power are enhanced following MitoQ supplementation, which may be related to the augmentation of skeletal muscle PGC1α expression following acute exercise. However, these effects do not appear to be related to an effect of MitoQ supplementation on exercise-induced oxidative stress or training-induced mitochondrial biogenesis in skeletal muscle.

Abstract
Objective: To compare the survival outcome in patients with synchronous colorectal cancer liver metastasis receiving neoadjuvant chemotherapy followed by hepatic surgery versus upfront surgery strategies. Methods: A retrospective cohort study was carried out. Data of patients undergoing surgery at the Department of Hepatopancreatobiliary Surgery Unit I of Peking University Cancer Hospital from January 2008 to December 2018 for initially resectable synchronous colorectal liver metastasis were retrospectively collected. A total of 282 cases were enrolled, including 244 in the neoadjuvant chemotherapy group, 38 in the upfront surgery first group. The overall survival (OS) and progression-free survival (PFS) of the two groups were compared. A propensity score risk adjustment was used to eliminate potential bias between groups, and the covariates including sex, age, location of primary tumor, T stage, clinical risk score (CRS), RAS gene status, adjuvant chemotherapy, and resection margin status were included for adjustment. Results: In the neoadjuvant chemotherapy group, 244 cases received 4 (1-15) cycles of chemotherapy before hepatic resection, among whom 207 cases received oxaliplatin-based regimens, 37 cases received irinotecan-based regimens, and 90 cases received combined targeted agents in the first line treatment. The median follow-up time was 30 (5-134) months, and loss of follow-up was 1%. Before adjustment, Kaplan-Meier survival analysis showed that the 1-year and 3-year OS rates in the neoadjuvant chemotherapy group (95.1% and 66.4%) were better than those in the upfront surgery first group (94.7% and 51.5%, P=0.026); 1-year and 3-year PFS rates in neoadjuvant chemotherapy group (51.0% and 23.4%) were also better than those in surgery first group (39.5% and 11.5%, P=0.039). After propensity score risk adjustment, Cox multivariate analysis indicated that neoadjuvant chemotherapy was an independent protective factor of PFS (HR=0.664, 95% CI: 0.449-0.982, P=0.040), however, neoadjuvant chemotherapy was not an independent protective factor of OS (HR=0.651, 95% CI: 0.393-1.079, P=0.096). Subgroup analysis showed that the 1-year and 3-year OS rates in the patients with response to the first line treatment (194, including complete remission, partial remission and reduction but not partial remission) (96.9% and 67.1%) were better than those in the upfront surgery group (94.7% and 51.5%, P=0.026) after adjustment. However, the 1-year and 3-year OS rates in the patients without response to the first line treatment (50, including tumor progression or enlargement) were 90.0% and 63.3%, respectively, which were not significantly different with 94.7% and 51.5% in the upfront surgery group (P=0.310) after adjustment. Conclusions: For patients with resectable synchronous colorectal cancer liver metastasis, liver resection after neoadjuvant chemotherapy can provide longer PFS than upfront surgery. Although the whole OS benefit is not significant, patients with effective neoadjuvant first-line chemotherapy have better OS than those undergoing upfront surgery.

Abstract
Objective: Liver is the most common site of distant metastasis in colorectal cancer patients. Currently, surgical resection of colorectal liver metastasis (CRLM) still remains the most curative therapeutic option which is associated with long-term survival. However, the outcome of CRLM patients with bilobar multiple lesions has been reported to be extremely poor due to the complex techniques of the surgery and the difficulties to achieve a negative resection margin. In this study, postoperative long-term outcome in patients with bilobar versus unilobar multiple CRLM undergoing surgical resection were compared and the prognostic factors of CRLM were analyzed. Methods: A retrospective cohort study was performed. The clinicopathological data were collected retrospectively from patients with multiple CRLM who received liver resection between January 2002 and November 2018 at our department. Inclusion criteria: (1) All CRLM lesions were confirmed by preoperative enhanced CT or MRI and enhanced ultrasonography. (2) All CRLM lesions were resectable either initially or converted by systemic treatments. The CRLM patients were considered as resectable, if their extrahepatic diseases were able to be completely removed. (3) Sufficient remnant liver volume was required to maintain normal liver function, which was defined by the ratio of remnant liver volume to total liver volume (RLV-TLV), of greater than 30% in general or 40% for the patients undergoing chemotherapy. (4) Medical records and follow-up information were intact. Those undergoing multiple operations after recurrence, with R2 resection, or with a single CRLM lesion were excluded. Patients were divided into bilobar and unilobar group according to tumor distribution. One-to-one propensity score matching (PSM) was performed to balance the covariates between the bilobar group and unilobar group. After PSM, the differences in long-term outcomes between the two groups were compared. Results: A total of 491 patients met the inclusion criteria, 344 (69.6%) with bilobar and 147 (30.4%) with unilobar CRLM. In the propensity-score-matched population (bilobar, 143; unilobar, 143), baseline characteristics were similar between the two groups. The 1-, 3-, and 5-year overall survival rates in the bilobar group were 91.6%, 52.1%, and 35.3% respectively, compared with 93.7%, 56.8%, and 43.8% in the unilobar group, and the difference was not statistically significant (P=0.204). The 1-, 3-, and 5-year recurrence-free survival rates in the bilobar group were 45.7%, 33.7%, and 33.7% respectively, compared with 62.5%, 44.1%, and 42.1% in the unilobar group, and the difference was not statistically significant (P=0.075). No significant difference was found in liver-only recurrence (45.6% in bilobar vs. 53.3% in unilobar, P=0.543). Univariate analysis showed that N stage of primary tumor, diameter of the largest liver metastases, carcinoembyonic antigen level, RAS gene status and clinical risk score (CRS) were significantly associated with the prognosis of CRLM (all P<0.05). Multivariate analysis indicated that diameter of largest liver metastases > 5 cm (HR=1.888, 95% CI: 1.251-2.848, P=0.002), CRS≥3 (HR=1.552,95% CI:1.050-2.294, P=0.027) and RAS gene mutation (HR=1.561, 95% CI: 1.102-2.212, P=0.012) were independent risk factors of poor overall survival after hepatectomy. Conclusions: Tumor distribution may not affect the prognosis of multiple CRLM after resection. Surgical removal in patients with bilobar multiple CRLM provides comparable long-term survival to unilobar multiple CRLM.

Abstract
β-delayed one-proton emissions of ^{22}Si, the lightest nucleus with an isospin projection T_{z}=-3, are studied with a silicon array surrounded by high-purity germanium detectors. Properties of β-decay branches and the reduced transition probabilities for the transitions to the low-lying states of ^{22}Al are determined. Compared to the mirror β decay of ^{22}O, the largest value of mirror asymmetry in low-lying states by far, with δ=209(96), is found in the transition to the first 1^{+} excited state. Shell-model calculation with isospin-nonconserving forces, including the T=1, J=2, 3 interaction related to the s_{1/2} orbit that introduces explicitly the isospin-symmetry breaking force and describes the loosely bound nature of the wave functions of the s_{1/2} orbit, can reproduce the observed data well and consistently explain the observation that a large δ value occurs for the first but not for the second 1^{+} excited state of ^{22}Al. Our results, while supporting the proton-halo structure in ^{22}Al, might provide another means to identify halo nuclei.

Abstract
OBJECTIVE To explore the sensitivity of Culex pipiens pallens to common chemical insecticides in the southwestern region of Shandong Province, so as to provide a theoretical basis for the development of reasonable and effective mosquito control measures. METHODS The resistance of Cx. pipiens pallens larvae to 5 chemical insecticides, such as cypermethrin, deltamethrin, DDVP, propoxur, and acetofenate were tested by using the WHO biological test method in 2018, and the co-toxicity coefficients after compounding the above-mentioned insecticides were tested by using a drug compounding method. RESULTS The resistance indexes of Cx. pipiens pallens to cypermethrin, deltamethrin, DDVP, propoxur, and acetofenate in 3 cities were 144.43-557.54, 118.17-445.33, 6.44-19.00, 2.37-8.10, and 0.88-2.98, respectively, and expect the difference between the DDVP resistances of Cx. pipiens pallens in Jining City and Heze City was not statistically significant (P > 0.05), all the other differences were statistically significant (all P < 0.05). The synergistic coefficients of cypermethrin + DDVP, cypermethrin + propoxur, DDVP + acetofenate, and propoxur + acetofenate were 199.58 - 456.95, 190.56 - 292.37, 123.32 - 319.24, and 192.31 - 367.32, respectively. The lower synergism was observed by using the mixture of DDVP + propoxur (synergistic coefficient: 99.87-108.36) . CONCLUSIONS After decades of chemical control, Cx. pipiens pallens in the southwestern region of Shandong Province has produced different degrees of resistance to common chemical insecticides. Therefore, comprehensive control measures should be taken to control mosquito breeding and prevent the development of insecticide resistance.

Abstract
Objective: To compare the etiology and incidence of pulmonary infection in patients with esophageal carcinoma accompanied by esophagotracheal fistula before and after the airway stent implantation. Methods: The clinical records of patients with esophageal carcinoma accompanied by esophagotracheal fistula in Respiratory Department and Oncology Department of Meitan General Hospital were retrospectively analyzed from March 2008 to January 2018. The demographic data, comorbidities, pathological results and etiology were collected before and after tracheal stents were implanted in all patients. The incidence of pulmonary infection was analyzed, and the classification of etiology was compared before and after tracheal stents implantation. Results: A total of 100 patients were included in the study. The incidence rate of pulmonary infection before stents implantation was 83.0%. A total of 105 bacterial strains were cultured, including 73 strains of gram-negative bacteria (69.5%) and mainly pseudomonas aeruginosa, 5 strains of gram-positive bacteria [all methicillin-resistant staphylococcus aureus (MRSA)] (4.8%), and 27 strains of fungi (25.7%) and mainly candida albicans. The incidence rate of pulmonary infection was lowered to 53.0% after tracheal stents implantation (χ(2)=29.102, P<0.001). A total of 79 bacterial strains were cultured, and the main bacteria were still gram-negative bacteria and fungi, in which pseudomonas aeruginosa and candida albicans accounted for the majority. However, 13 strains of MRSA were cultured (16.5%), significantly higher than those before stents implantation (χ(2)=7.451, P=0.005). Conclusions: The incidence rate of pulmonary infection in patients with esophageal carcinoma accompanied by esophagotracheal fistula is very high. Gram-negative bacteria and fungi are the main etiologies. Tracheal stents implantation can effectively reduce the incidence of pulmonary infection. However, the incidence rate of MRSA is significantly increased after stents implantation.

All the groups of patients received PCIA pump, in the H group, the PCIA reagent was composed of 120 μg/kg hydromorphone and 5 mg tropisetron in 100 ml of normal saline. In comparison, PCIA regiment was composed of 120 μg/kg hydromorphone, 1 μg/kg dexmedetomidine and 5 mg tropisetron in 100 ml of normal saline in the D1 group, while 120 μg/kg hydromorphone, 2 μg/kg dexmedetomidine and 5 mg tropisetron in 100 ml of normal saline in the D2 group. The visual analogue scale (VAS) score, the observer's assessment of alertness/sedation scale (OAA/S) score, patients' satisfaction index, consumption of hydromorphone, the additional dose of morphine, the effective pressing times of PCIA and adverse reactions were recorded in detail at 0, 0.5, 1, 4, 12 and 24 hours after the patients underwent TACE. Results: The total consumptions of hydromorphone were (4.3±0.1), (4.1±0.1), and (3.8±0.1) mg in group H, D1, and D2, respectively, and the effective pressing times were 13±3, 6±2 and 2±1, the additional doses of morphine were (30±5), (15±3), and (3±1) mg, and adverse reaction rates were 45.0%, 28.3%, and 10.0%, respectively. The manifestations mentioned above in D2 group were significantly lower than those in group H and group D1 (P<0.05). Immediately and 5 min after embolization, at the end of surgery and 0.5, 1, 4, 12 and 24 h after surgery, the VAS scores in the D2 group were 1.9±0.2, 2.1±0.3, 1.8±0.4, 1.8±0.3, 1.7±0.3, 1.6±0.3, 1.3±0.2, 1.3±0.3, respectively, lower than those in group H and group D1 (P<0.05); The satisfaction index in D2 group at these times were 8.7±1.1, 8.9±0.8, 9.2±0.9, 9.0±0.7, 9.1±0.8, 9.0±0.6, 9.1±0.7, 9.2±0.9, respectively, higher than those in group H and group D1 (P<0.05). No breath depression happened in these three groups. Conclusion: The formula of hydromorphone combined with dexmedetomidine to patients undergoing TACE is greatly safe and efficient, with advantages in alleviating pain, reducing hydromorphone consumption and the incidence of adverse reaction of hydromorphone, and without breath depression.

Abstract
The CUORE experiment, a ton-scale cryogenic bolometer array, recently began operation at the Laboratori Nazionali del Gran Sasso in Italy. The array represents a significant advancement in this technology, and in this work we apply it for the first time to a high-sensitivity search for a lepton-number-violating process: ^{130}Te neutrinoless double-beta decay. Examining a total TeO_{2} exposure of 86.3 kg yr, characterized by an effective energy resolution of (7.7±0.5) keV FWHM and a background in the region of interest of (0.014±0.002) counts/(keV kg yr), we find no evidence for neutrinoless double-beta decay. Including systematic uncertainties, we place a lower limit on the decay half-life of T_{1/2}^{0ν}(^{130}Te)>1.3×10^{25} yr (90% C.L.); the median statistical sensitivity of this search is 7.0×10^{24} yr. Combining this result with those of two earlier experiments, Cuoricino and CUORE-0, we find T_{1/2}^{0ν}(^{130}Te)>1.5×10^{25} yr (90% C.L.), which is the most stringent limit to date on this decay. Interpreting this result as a limit on the effective Majorana neutrino mass, we find m_{ββ}<(110-520) meV, where the range reflects the nuclear matrix element estimates employed.

Abstract
Enterovirus type 71 ( EV71) infections are mainly found in infants. The severe cases are characterised by nervous system damage, acute circulatory and respiratory failures. So far, there has been no report of EV71 infection involving central nervous system in teenagers or young adults. We first reported a case of 15-year-old Han Chinese male who was infected by EV71, developed neurogenic pulmonary oedema rapidly, and had the risk factors including hyperglycaemia, significant leukocytosis and acute flaccid paralysis. The nucleic acids for EV71 were positive by Reverse transcriptase polymerase chain reaction (RT-PCR). The patient didn't belong to high risk population. Maculopapular rashes and blisters were also not found in hand, foot and mouth. These might be responsible for the failure to make an early diagnosis. (Hong Kong j.emerg.med. 2014;21:176-180)

Abstract
The poor egg-laying rate of geese hinders the development of the goose industry; therefore, the reproductive performance of geese is an important area of investigation. To evaluate the relationship between photoperiod, reproductive hormones, and reproductive activity during the egg-laying cycle in geese under natural conditions, we collected blood samples from Sichuan white geese and Xupu geese to quantify changes in prolactin (PRL), estradiol (E2), vasoactive intestinal polypeptide (VIP), follicle stimulating hormone (FSH), gonadotropin-inhibitory hormone (GnIH), and luteinizing hormone (LH). We also calculated the rate of egg laying for the two populations during the egg-laying cycle. We show that the egg-laying rate and the serum concentration of some hormones (PRL, E2, VIP, FSH, GnIH, and LH) differed significantly between the two populations during the pre-laying, laying, and ceased-laying periods. Serum LH concentrations may be associated with maturation of the ovary and oviducts, whereas FSH, PRL, and GnIH play important roles in egg laying. These results provide a useful resource for future studies examining the laying rate in geese.

Abstract
Chicken meat quality is becoming increasingly important among breeders and consumers. To understand the effect of feeding conditions on chicken meat quality, we investigated the profiles of genes expressed in chicken breast muscle. Using RNA sequencing, we identified 336, 321, and 387 differentially expressed genes among Chengkou, Daninghe, and Qingjiaoma chickens under scatter- and captivity-feeding conditions. Twenty-two genes differentially expressed between different feeding conditions were shown to be common among the three breeds. Seven of these genes were assessed by real-time quantitative PCR, which confirmed the findings of RNA sequencing and suggested that the results were viable. The differentially expressed genes showed enrichment for a series of significant pathways, including energy metabolism, xenobiotics biodegradation and metabolism, and the immune system. These results provide a solid foundation for elucidating the molecular mechanisms underlying chicken meat quality.

Abstract
HIV genotyping has led to conflicting results between laboratories. Therefore, identifying the most accurate gene combinations to sequence remains a priority. Datasets of Chinese HIV subtypes based on several markers and deposited in PubMed, Metstr, CNKI, and VIP databases between 2000 and 2015 were studied. In total, 9177 cases of amplification-positive samples from 26 provinces of China were collected and used to classify HIV subtypes based on eight individual genes or a combination thereof. CRF01_AE, CRF07_BC, CRF08_BC and B were the prevalent HIV subtypes in China, accounting for 84.07% of all genotypes. Gag/Env sequencing classified a greater number of HIV subtypes compared to other genes or combination of gene fragments. The geographical distribution of Gag and Gag/Env genotypes was similar to that observed with all genetic markers. Further principal component analysis showed a significantly different geographical distribution pattern of HIV in China for HIV genotypes detected with Gag/Env, which was in line with the distribution of all HIV genotypes in China. Gag/Env sequences had the highest diversity of the eight markers studied, followed by Gag and Gag/Pol/Env; Pol/Env polymorphisms were the least divergent. Gag/Env can serve as a high-resolution marker for HIV genotyping.

Abstract
Formalin fixation and paraffin embedding is widely used for convenient and long-term storage of tumor tissue and precious sources to perform genetic studies. However, DNA fragmentation is one of the major flaws of genomic DNA isolation from formalin fixation tissues, which limits its further usage. Here, we present an improved method for isolating high-quality genomic DNA from formalin fixation tissue. We obtained high-quality genomic DNA of more than 20 kb from samples frozen for more than 2 years. Furthermore, to verify DNA quality, the whole mitochondrial DNA (mtDNA) genomes from the normal and tumor tissue of the same patient were successfully amplified with two overlapping PCR fragments comprising more than 8379 bp in length for each fragment. In addition, the whole genomes were sequenced with a 48-well based primer panel in order to avoid potential sequencing errors from artificial recombination, which was further confirmed with an mtDNA phylogenetic strategy. Our improved DNA extraction method from formalin fixation tissue and sequencing strategy for entire mtDNA genomes will generate unambiguous sequence analysis results for clinical samples.

Abstract
OBJECTIVE To explore whether the ABL(Δexon7) and ABL(35INS) spliceosome contributed to TKIs resistance. METHODS Screening ABL(Δexon7) and ABL(35INS) in 74 normal people and 76 CML patients (53 patients in remission and 23 patients with TKIs resistance) by using polyacrylamide gel electrophoresis combined with cloning sequencing. RESULTS A novel spliceosome ABL(Δexon7+ 35INS) (ABL(Δexon7) and ABL(3)5INS existed at the same time) was identified and the mutation was detected in 8 (10.8%) of 74 normal people, 4 (7.5%) of 53 remission patients and 2 (8.7%) of 23 resistant patients. While 47 (63.5%) cases expressed ABL(Δexon7) and 8 (10.8% ) cases expressed ABL(35INS) in 74 healthy people, 30 (56.6%) cases expressed ABL(Δexon7) and 5 (9.4% ) cases expressed ABL(35INS) in 53 remission patients, 12 (52.2%) cases expressed ABL(Δexon7) and 3(13.0%) cases expressed ABL(35INS) in 23 resistant patients. Three kinds of spliceosome in all groups had no statistical difference. CONCLUSION ABL(Δexon7+ 35INS), ABL(Δexon7) and ABL(35INS) may be not uncommon in ABL gene and were unrelated to resistance in CML with TKIs treatment. ABL(35INS) were often accompanying with exon 7 deletion.

Abstract
OBJECTIVE To explore the expression of PTEN in squamous-cell lung cancer(SQCLC) and its clinical significance. METHODS A total of 50 patients with SQCLC, including 43 males, 7 females, aged 40 to 83(average age 66 ) years, in Meitan General Hospital from May 2009 to July 2013 were included. Tumor adjacent tissues from 10 patients, including 9 males, 1 female, aged 42 to 79 (average age 59 )years, and 13 patients with benign pulmonary disease tissues, including 11 males, 2 females, aged 34 to 76 (average age 58 ) years were also included as the controls. The expression of PTEN protein was detected by using immunohistochemistry (S-P)method and compared among SQCLC tissues tumor adjacent tissues and benign disease tissues. The correlations of expression of PTEN protein with gender, age, smoking status, lymph node metastasis, clinical stages and differentiation grades were performed. RESULTS (1) PTEN expression was low in 50 cases SQCLC, while there was a high expression in the tumor adjacent tissues and benign disease tissues. The PTEN protein positive rate of the SQCLC cases (20%, 10/50) was significantly lower than that of cases of tumor adjacent tissues and benign disease tissues (8/10, 12/13), χ(2)=23.542, P<0.01. (2) In the SQCLC group, the expression of PTEN protein was significantly related to differentiation grades and lymph node metastasis (P<0.05), but not gender, age, smoking status, and clinical stages (P>0.05). CONCLUSIONS The lower expression of PTEN in SQCLC was associated with high degree of malignancy and lymph node metastasis. The lost of expression of PTEN may serve as a marker for evaluation of malignancy and an independent factor for prognosis.

Abstract
To investigate the effects of feed condition and breed on the level of DNA methylation for the uncoupling protein 3 (UCP3) gene, which is an important candidate gene for regulating intramuscular fat (IMF) content in chicken breast muscle, breast muscle of Daninghe (DNH) and Qingjiaoma (QJM) chickens under scatter-feed and captivity-feed conditions was analyzed. Using RNA sequencing, 47 and 113 candidate genes were determined to be related to feed conditions and breed, respectively, and 7 differentially expressed genes were confirmed by real-time quantitative PCR, including UCP3. The mRNA levels of UCP3 were significantly different between the 2 feed conditions. The DNA region from bp +1700 to +2459 of the UCP3 gene was studied using the bisulfite sequencing method and contained 46 methylation sites and 3 CpG islands. The results showed that the methylation level of this UCP3 region was lower in DNH chickens (0.77% to 0.88%, P = 0.012) and QJM chickens (0.88% to 0.91%, P = 0.20) under scatter-feed conditions than under captivity-feed conditions. The mean methylation level of UCP3 in DNH chickens was lower than that in QJM chickens under scatter-feed conditions (DNH to QJM, 0.77% to 0.88%, P = 0.007), which suggests that breed affects the mean methylation level of UCP3 under scatter-feed conditions. In summary, our findings suggest that feed condition and breed affect the methylation of UCP3 in chicken breast muscle.

Abstract
We report the results of a search for neutrinoless double-beta decay in a 9.8 kg yr exposure of (130)Te using a bolometric detector array, CUORE-0. The characteristic detector energy resolution and background level in the region of interest are 5.1±0.3 keV FWHM and 0.058±0.004(stat)±0.002(syst)counts/(keV kg yr), respectively. The median 90% C.L. lower-limit half-life sensitivity of the experiment is 2.9×10(24) yr and surpasses the sensitivity of previous searches. We find no evidence for neutrinoless double-beta decay of (130)Te and place a Bayesian lower bound on the decay half-life, T(1/2)(0ν)>2.7×10(24) yr at 90% C.L. Combining CUORE-0 data with the 19.75 kg yr exposure of (130)Te from the Cuoricino experiment we obtain T(1/2)(0ν)>4.0×10(24) yr at 90% C.L. (Bayesian), the most stringent limit to date on this half-life. Using a range of nuclear matrix element estimates we interpret this as a limit on the effective Majorana neutrino mass, m(ββ)<270-760 meV.

Abstract
The median survival for metastatic melanoma is in the realm of 8-16 months and there are few therapies that offer significant improvement in overall survival. One of the recent advances in cancer treatment focuses on epigenetic modifiers to alter the survivability and immunogenicity of cancer cells. Our group and others have previously demonstrated that pan-HDAC inhibitors induce apoptosis, cell cycle arrest and changes in the immunogenicity of melanoma cells. Here we interrogated specific HDACs which may be responsible for this effect. We found that both genetic abrogation and pharmacologic inhibition of HDAC6 decreases in vitro proliferation and induces G1 arrest of melanoma cell lines without inducing apoptosis. Moreover, targeting this molecule led to an important upregulation in the expression of tumor associated antigens and MHC class I, suggesting a potential improvement in the immunogenicity of these cells. Of note, this anti-melanoma activity was operative regardless of mutational status of the cells. These effects translated into a pronounced delay of in vivo melanoma tumor growth which was, at least in part, dependent on intact immunity as evidenced by the restoration of tumor growth after CD4+ and CD8+ depletion. Given our findings, we provide the initial rationale for the further development of selective HDAC6 inhibitors as potential therapeutic anti-melanoma agents.

Abstract
Numerous studies have evaluated the association between the T174M polymorphism in the angiotensinogen (AGT) gene and myocardial infarction (MI) risk. However, the specific association remains controversial because of small sample sizes and varied study designs among different studies. We performed a meta-analysis to assess this correlation. A comprehensive search was conducted to identify all published articles regarding the association between the AGT gene T174M polymorphism and MI risk from different databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated, and heterogeneity and publication bias were assessed. A total of 1032 patients with lung cancer and 1286 controls from 6 comparative studies were included in this meta-analysis. The results revealed a significant association between the AGT gene T174M polymorphism and MI risk (MM vs TT: OR = 2.87, 95%CI = 1.71-4.83; dominant model: OR = 1.57, 95%CI = 1.10-2.25; recessive model: OR = 0.41, 95%CI = 0.25-0.66). In subgroup analysis by nationality, we observed a significant association between the AGT gene T174M polymorphism and susceptibility to MI in both Caucasian and Asian populations. In conclusion, the T174M polymorphism in the AGT gene may be related to an increased risk of MI. Further larger studies are needed to confirm these conclusions.

Abstract
OBJECTIVES The frontal sinus has the most complex and variable drainage routes of all paranasal sinus regions. The goal of this study was to identify these anatomical factors and inflammation areas relating to chronic frontal sinusitis by comparing radiological presentations in patients with and without frontal sinusitis. METHODS All adult patients with chronic rhinosinusitis who had received computed tomography (CT) scans of the nasal cavities and paranasal sinuses between October 2010 and September 2011. Logistic regression analysis was used to compare the distribution of various frontal recess cells and surrounding inflammatory conditions in patients with and without frontal sinusitis. RESULTS Analysis of 240 sides of CT scans was performed with 66 sides excluded. The opacification of the frontal recess and sinus lateralis demonstrated a strong association with an increased presence of frontal sinusitis by multiple logistic regression models. CONCLUSION Opacification of the frontal recess and sinus lateralis was found to be associated with a significantly increased risk of frontal sinusitis and developing severe blockage of drainage pathways. It provides evidence that mucosal inflammation disease in these two areas is a very important factor leading to chronic frontal sinusitis.

Abstract
Familial gigantiform cementoma is a rare benign fibrocemento-osseous lesion of the jaws that can cause severe facial deformity. It has an autosomal dominant mode of inheritance, but varies in its phenotype. It is more common in white, African, and East-Asian patients. Here we report what is to our knowledge the first distinctive Chinese family with familial gigantiform cementoma involving 4 generations and 13 patients, and which suggests that the tumour presents with 3 distinctive growth phrases.

Abstract
Recent studies have found that glucocorticoids are closely associated with oncogenesis and the development of many types of tumors. The aim of this study was to observe the effect of dexamethasone on the growth and angiogenesis of transplanted Lewis lung carcinoma in mice. Lewis lung carcinoma cells were inoculated subcutaneously into the right axilla of C57BL/6 mice, and the mice were randomly divided into 3 groups: the control group, cisplatin group, and dexamethasone group. From day 7 after inoculation, all the mice were given different treatments for 10 days, and changes in xenograft tumor volumes were monitored. All mice were sacrificed on day 17, and the tumors were obtained and weighed and the tumor inhibitory rate was calculated. The expression levels of hypoxia inducible factor 1α (HIF-1α) and vascular endothelial growth factor (VEGF), as well as the microvessel density (MVD) in the tumor mass, were measured by immunohistochemistry. Tumor growth was suppressed in the cisplatin group and dexamethasone group. The weights of tumors were markedly decreased in the cisplatin group and dexamethasone group compared with the control group (P < 0.05). The expression levels of HIF-1α and VEGF and the MVD were significantly lower in the cisplatin group and dexamethasone group than in the control group (P < 0.05). However, these levels were not significantly different between the cisplatin group and dexamethasone group (P > 0.05). Dexamethasone can effectively inhibit the growth and angiogenesis of Lewis lung carcinoma by inhibiting the expression of HIF-1α and VEGF.

Abstract
This study investigated the cytotoxicity of combined mycotoxins of ochratoxin A (OTA), zearalenone (ZEA), and/or α-zearalenol (α-ZOL). The cytotoxicity of two mycotoxin combinations (two two-toxin combinations and one three-toxin combination) on human Hep G2 cells was evaluated using a tetrazolium salt (MTT) assay and isobologram analysis. Our results demonstrated significant cytotoxic effects of the two-toxin combination and the three-toxin combination on Hep G2 cells in a time- and concentration-dependent manner. The combination indexes (CI) were 2.73-7.67 for the OTA+ZEA combination and 1.23-17.82 for the OTA+α-ZOL combination after 24 h, 48 h, and 72 h of exposure at all inhibit concentration (IC) levels (IC10-IC90), indicating an antagonism. The CIs of the ZEA+α-ZOL combination were 1.29-2.55 after 24 h and 72 h of exposure (IC10-IC90), indicating an antagonism. The CIs of the ZEA+α-ZOL combination were 0.74-1.68 after 48 h of exposure, indicating synergism (IC80-IC90), additive effects (IC50-IC70), or antagonism (IC10-IC40). For the OTA+ZEA+α-ZOL combination, the CIs were 1.41-14.65 after 24 h, 48 h, and 72 h of exposure (IC10-IC90), indicating an antagonism.

Abstract
Hunan locates in the south-central part of China, to the south of the middle reaches of the Yangtze River and south of Lake Dongting. According to the historical records, the peopling of Hunan by modern human ancestors can ascend to 40 thousand years ago. Thus, to trace the ancient maternal components can offer further insight into the origin of south-central China. In this study, we investigated the mitochondrial DNA of 114 individuals from Hunan Province (including 34 Han, 40 Tujia and 40 Miao). Hypervariable regions I and II of the mtDNA control region were sequenced, and the relative diagnostic variations in coding region according to the updated worldwide phylogeny tree were selected and typed by restriction fragment length polymorphism analysis or direct sequencing. All individuals were classified into specific (sub)haplogroups. By comparison with the surrounding populations, southern China-prevalent haplogroups were detected with relative higher frequency in the Tujia and Miao ethnic populations, such as haplogroup B, with more than 20%, lacking in the Han population, which illustrated its southern origin characters. In addition, we also detected northern of East Asia prevalent haplogroups with a relative higher frequency in Tujia populations than in the Miao and Yao ethnic groups, implying a gene flow from Han populations. However, the language-clustering tendency was supported by our principal component analysis and further genetic estimation results. Han and ethnic groups in central China exhibited specific ancestors related to their closer language affinity, although there was extensively genetic admixture between Han and ethnic groups.

Abstract
OBJECTIVES Histamine is an important chemical mediator in both nasal and bronchial inflammation in patients with allergic rhinitis and asthma. The effect of histamine receptor-1 antagonists on nasal mucosa in vivo is well known, however, the effect on tracheal smooth muscle has rarely been explored. The purpose of this study was to determine the effects of fexofenadine on isolated tracheal smooth muscle in vitro. METHODS Six tracheal strips were used for each experiment, and one untreated strip served as a control. We examined the effectiveness of fexofenadine on isolated rat tracheal smooth muscle by testing the effect on: 1) tracheal smooth muscle resting tension; 2) contraction caused by 10E-6 M methacholine as a parasympathetic mimetic; and 3) electrically induced tracheal smooth muscle contractions. RESULTS The results indicated that addition of methacholine caused the trachea to contract in a dose-dependent manner. The addition of fexofenadine at a dose of 10E-4 M elicited a significant relaxation response compared to 10E-6 M methacholine-induced contraction. There were no detectable changes in the peak tension of electrical field stimulation-induced contractions in the fexofenadine group. CONCLUSION High concentrations of fexofenadine had an anti-cholinergic effect. In addition to diminishing histamine-mediated allergic symptoms, fexofenadine may have a potentially therapeutic implication in alleviating asthma-related symptoms due to reducing methacholine-induced contractions of tracheal smooth muscle though these aspects were not studied.

Abstract
OBJECTIVES To examine the anatomical features of the anterior opening of the vidian canal using three-dimensional (3D) computed tomography (CT) images of the bone. METHODS We reviewed 62 patients who had undergone bilateral vidian neurectomies. One hundred and twenty-four vidian canals and their surrounding anatomies were analyzed. 3D images were reconstructed using algorithms and compared with conventional two-dimensional (2D) CT images. RESULTS A bony prominence that overlaid the vidian canal along the sphenoid sinus floor was found in 60 (48.39 %) canals. Pneumatization of the pterygoid process was observed in 45 sides (36.29%). No significant discrepancy was found in detecting these variances between the 2D and the 3D images. The presence of a surgically favorable gap between the palatine and the sphenoid bone was seen in 25 sides (20.16%) without significant association with pterygoid process pneumatization or vidian canal protrusion. This gap was not identified on the 2D CT scans. CONCLUSION 3D CT reconstruction images of bone provide superior delineation of the gap between the palatine and the sphenoid bone, which is a critical variation for vidian neurectomy. This useful method may contribute to better prediction and guidance of the surgical approach to the vidian canal and pterygopalatine fossa.

Abstract
Paulownia kawakamii is a fast-growing timber tree. In this study, 21 primer sets were developed using an enriched genomic library. The genetic diversity was measured in one P. kawakamii population. The number of alleles per locus ranged from 2 to 19. The observed and expected heterozygosities varied from 0.158 to 0.842 (mean = 0.421) and from 0.376 to 0.952 (mean = 0.771), respectively. All 21 loci were also polymorphic in closely related species (P. tomentosa, P. elongata, and P. fortunei). The described markers will be useful in future population genetic studies and molecular breeding of these Paulownia species.

Abstract
Depletion and dysfunction of dendritic cells in the lung can induce local immunoparalysis, which often leads to multiple organ dysfunction syndrome (MODS)-associated mortality. A therapeutic strategy that reverses this immunoparalysis is required. In the present study, we examined the effects of in vivo Fms-like tyrosine kinase 3 ligand (Flt3L) treatment on zymosan (zym)-induced secondary lung injury and dendritic cell (DC) immunoparalysis. BALBc mice were divided randomly into four groups (20/group): (1) sham [intraperitoneal (i.p.) saline] + vehicle [subcutaneous (s.c.) 0·01% mouse serum albumin]; (2) sham + Flt3L (s.c.); (3) zym (i.p.) + vehicle; and (4) zym + Flt3L. Injections were for 9 consecutive days; 12 days later we examined: survival rate (monitored for 12 days); lung tissue histopathology (haematoxylin and eosin staining); plasma indices of lung function (pH, PaO(2) , PaCO(2) , HCO(3) (-) ); DC subsets in lung tissue; and lung DCs production of interleukin (IL)-12p70 and IL-10. Zym administration resulted in increased mortality associated with significant lung histopathological changes and abnormal blood gas indices; however, these pathological changes were ameliorated by Flt3L treatment. Zym injections also resulted in significant reductions in DC subsets recovered from lungs [CD11c(+) major histocompatibility complex (MHC)-II/I-A(d+) , CD11c(+) CD11b(+) and CD11c(+) B220(+) ]. Importantly, in-vivo Flt3L treatment reversed these trends for DC immunoparalysis by increasing the percentages of recovered DC subsets concomitant with increased DC production of IL-12 p70 and decreased IL-10 production. These results suggest that Flt3L may have therapeutic potential for reversing DC immunoparalysis and ameliorating lung injury secondary to MODS.

Abstract
We investigated factors such as time span between transplantation and having offspring, the dosage of immunosuppressive agents during fertilisation and the effects of fertilisation on recipient's renal allograft function in 212 male recipients registered at eight Chinese organ transplantation centres. Our results are as follows: the 212 male renal allograft recipients conceived with their wives between 15 and 204 months after transplantation. The wives who became pregnant at 15-24 months after the renal transplantation gave birth to a total of 20 babies with an average weight of 3115 ± 517 g, of which 3 (15.0%) were premature. The wives who became pregnant at 25-204 months after the renal transplantation gave birth to a total of 196 babies with an average weight of 3384 ± 438 g, of which 6 (3.1%) were premature. All recipients had normal renal function during the fertile period. In conclusion, the fertility capacity of male renal allograft recipients was associated with the time after transplantation and the dose of immunosuppressive agents used during fertilisation. It might be helpful to have a fertility capacity evaluation before fertilisation. There were no effects of fertility on renal allograft function.

Abstract
Polynorbornenes appended with porphyrins containing a range of different linkers are synthesized. The use of bisamidic chiral alanine linkers between the pending porphyrins and the polymeric backbone has been shown to bring the adjacent porphyrin chromophores to more suitable orientation for exciton coupling owing to hydrogen bonding between the adjacent linkers. The hydrogen bonding between the adjacent pendants in these polymers may induce a cooperative effect and therefore render single-handed helical structures for these polymers. Such a cooperative effect is reflected in the enhancement of FRET efficiencies between zinc-porphyrin and free base porphyrin in random copolymers.

Abstract
This study compared the accuracy of measurements of the skull base made using computed tomography (CT) images and an image-guided surgery system with those made using scientific callipers in order to evaluate the practicability of replacing conventional direct anatomical measurements with digitized techniques in skull base surgery. Important bony landmarks and parameters were measured using the three different methods in 25 cadaver skull bases. No statistically significant differences were observed between the methods. Coefficient of variation calculations indicated that data obtained from CT images was the most stable. Digital methods of navigation have the potential to reflect individual skull base anatomical features more accurately than traditional group-based data, but it is important to assess their accuracy. This study demonstrated that CT imageology and image-guided surgery systems can provide accurate anatomical measurements. Digital methods are also more flexible and less variable, and may have wide applications in this field. Though not perfect, digital imaging is a promising tool for skull base surgery.

Abstract
Genetic analyses of the lupus-prone NZM2410 mouse have identified multiple susceptibility loci on chromosome 7, termed Sle3 and Sle5. Both of these loci were contained within a large congenic interval, originally termed as Sle3 that strongly impacts a variety of myeloid and T-cell phenotypes and mediates fatal lupus nephritis when combined with Sle1. We have now produced two subcongenic strains, B6.Sle3 and B6.Sle5, carrying the Sle3 and Sle5 intervals separately and characterized their phenotypes as monocongenic strains and individually in combination with Sle1. Neither B6.Sle3 nor B6.Sle5 monocongenic strain develop severe autoimmunity; however, both of these intervals cause the development of severe glomerulonephritis when combined with Sle1. Thus, B6.Sle1Sle3 and B6.Sle1Sle5 exhibit splenomegaly, expansion of activated B and CD4+ T-cell populations and high levels of IgG and IgM autoantibodies targeting multiple nuclear antigens, intact glomeruli and various other autoantigens. In addition, B6.Sle1Sle3 mice also produced higher levels of IgA antinuclear autoantibodies, which were implicated in the development of IgA nephropathy. Our results indicate that Sle3 and Sle5 can independently complement with Sle1, through shared and unique mechanisms, to mediate the development of severe autoimmunity.

Abstract
Two dimers and a series of polymers with 5,6-endo pendant aryl groups that contain different substituents at the para positions were synthesized. The conformation and stereochemistry of the dimers and polymers were determined by nonlinear optical analysis (EFISH) as well as UV/Vis and 13C NMR spectroscopy. The chemical shifts of C7 for the polymers appeared as two peaks in the 13C NMR spectra when the substituents are electron-withdrawing groups. The percentage decrease in the relative extinction coefficient of the polymers, epsilon(d), was linearly related to the Hammett constant sigma. Polynorbornenes with electron-withdrawing substituents may adopt isotactic stereochemistry with all pendant groups aligned in one direction. The nature of the interactions between neighboring chromophores may be one of the most important factors in directing the stereoregularity and conformation of these polymers. The corresponding polymers derived from the exo isomers appeared to be less stereoregular.
