Abstract
Objective: To investigate the inplementation of cardiovascular surgery for congenital heart disease (CHD) in China. Methods: A cross-sectional study was carried out. The CHD cardiovascular surgery data collected by the Chinese Society of Extracorporeal Circulation from 2017 to 2021 in 31 provinces (autonomous regions/municipalities) of China were retrospectively reviewed, the implementation of CHD cardiovascular surgery in different provinces, regions, general/specialized hospitals, and different age groups (whether≤18 years old) were summarized, and the correlation analysis between the number of surgeries carried out in each province/region and the gross regional product and the number of the regional population was performed. Results: Between 2017 and 2021, the annual volume of CHD cardiovascular surgery was 77 120, 77 634, 81 161, 62 663 and 71 492, respectively, showing a decreasing trend. Meanwhile, the proportion of CHD patients aged≤18 years who underwent cardiovascular surgery also showed a downward trend, from 79.8% (61 557/77 120) in 2017 to 58.6% (41 871/71 492) in 2021 (P=0.027). The number of surgical cases varied greatly among different provinces, including 4 provinces with≥5 000 cases and 9 provinces with 2 000-5 000 cases. In the five years, the number of CHD cardiovascular surgeries in Central and East China was the largest, accounting for 41.1%-45.5% of the total surgical cases. The proportion of CHD surgery cases≤18 years old was the highest in Southwest China (69.7%-87.4%) and the lowest in Northeast China (28.2%-68.9%). Except for 2021, the number of cases carried out by each region between 2017 and 2020 was correlated with the gross regional product (r=0.929, 0.929, 0.893 and 0.964, respectively, all P<0.05) and the population (r=0.821, 0.893, 0.821 and 0.857, respectively, all P<0.05). Hospitals that performed more than 100 operations (20.5%±1.2% of the total number of hospitals) completed 86.2%±1.2% of the total number of operations in China during the 5-year period. In 2017 and 2021, the number of CHD cardiovascular surgeries preformed in children's/women's and children's specialized hospitals accounted for 24.3% (18 772/77 120) and 23.8% (17 012/71 492) of the total number of cases in China, respectively. Conclusions: From 2017 to 2021, the number of cardiovascular surgery for CHD decreases slightly, but the proportion of surgery for adult CHD patients increases significantly.There is a strong correlation between the number of CHD operations in each region and their economic development status. The scale of CHD cardiovascular surgery performed in children's hospitals/women's and children's hospitals accounts for about a quarter of the total volume in China.

Abstract
Rabies is a zoonotic viral disease characterized by an almost 100% fatality rate once symptoms appear. However, it can be prevented through timely postexposure prophylaxis (PEP). Currently, there is a growing trend to replace polyclonal rabies immune globulin (RIG) with monoclonal antibodies (mAbs) in rabies PEP. In this study, we developed a human bispecific antibody, GR1801, by combining two mAbs, A2 and B353, which target distinct epitopes. GR1801 is an asymmetric immunoglobulin G1 molecule, with one arm (A2 targeting epitope III) in fragment antigen-binding (Fab) form and the other arm (B353 targeting epitope I) in single-chain variable fragment (scFv) form, constructed using Knobs-into-Holes technology. GR1801 demonstrated the ability to neutralize 90 naturally occurring rabies virus (RABV) glycoprotein antigenic variants, 21 pseudotyped, and 18 live street RABVs, exhibiting broad-spectrum neutralizing activity. In vivo, GR1801 provided protection equivalent to that of human RIG in golden hamsters challenged with lethal RABV. In conclusion, these findings demonstrate the neutralization potency and breadth of GR1801, which can be a promising candidate drug for rabies PEP, and a comprehensive testing against a broad spectrum of Chinese prevalent RABVs will be investigated in great detail in the future for the in vitro and in vivo studies.

Abstract
Objective: To understand the knowledge, attitude, and current status of vaccination of herpes zoster vaccination among urban residents aged 25 years and above in China. Methods: In August to October 2022, a convenience sampling method was used to survey residents aged 25 years and above at 36 community centers in 9 cities across China. Questionnaires were used to collect basic information, knowledge, and attitude toward herpes zoster and its vaccination, as well as vaccination status and reasons for non-vaccination among residents. Results: A total of 2 864 urban residents were included in the study. The total score of residents' cognition of herpes zoster and its vaccine was 3.01±2.08, and the total score of their attitude was 18.25±2.76. Factors such as being male (β=-0.45, P<0.001), older than 40-59 years (β=-0.34, P=0.023) or ≥60 years (β=-0.68, P<0.001), married (β=-0.69, P=0.002) were negatively associated with knowledge score. The educational level of high school or secondary school (β=0.44, P=0.036), college (β=0.65, P=0.006), bachelor's degree and above (β=1.20, P<0.001), annual net household income ≥120 000 Yuan in 2021 (β=0.42, P=0.020), having urban employee medical insurance (β=0.62, P=0.030), having public or commercial medical insurance (β=0.65, P=0.033), and having a history of chickenpox (β=0.29, P=0.025) were positively associated with knowledge scores. Being male (β=-0.38, P=0.008) and not remembering a history of chickenpox (β=-0.49, P=0.012) were negatively associated with attitude scores. Annual net household income in 2021 was between 40 000-80 000 Yuan (β=0.44, P=0.032) or between 80 000-120 000 Yuan (β=0.62, P=0.002) or ≥120 000 Yuan (β=0.93, P<0.001), and a history of herpes zoster (β=0.59, P=0.004) were positively associated with attitude scores. Of the 2 864 residents surveyed, only 29 (1.01%) had received the herpes zoster vaccine, with a vaccination rate of 1.70% for those aged 50 years and above, with the main reason for non-vaccination being lack of knowledge about the herpes zoster vaccine, followed by the high price. 42.67% of the population said they would consider getting the herpes zoster vaccine in the future. Conclusion: Low knowledge of herpes zoster and its vaccine, positive attitudes towards the preventive effects of herpes zoster and its vaccine, and extremely low vaccination rates among the urban population in China call for multiple measures to strengthen health education and vaccination recommendations for residents, especially for the elderly, low-education and low-income populations.

Abstract
Anti-drug antibody (ADA) positivity is correlated with disease relapse risk when treated with monoclonal antibody (mAb) therapeutics. ADA evaluation can assist with interpreting pharmacokinetic, pharmacological, and toxicology results. Here, we established an ADA assay based on two steps of acid dissociation combined with a bridging immunoassay to provide a comprehensive validation strategy. The three-tiered sample analysis process included screening, confirmation, and titration assays using therapeutic HLX26 (targeting lymphocyte activation gene-3 [LAG-3]) as an example. The cut points were determined by testing 50 individual normal human serum samples, including screening cut point (SCP) (SNR: 1.08), confirmatory cut point (CCP) (% inhibition: 12.65), and titration cut point (TCP) (sample-to-noise ratio [SNR]: 1.17). The assay sensitivity, low positive control (LPC), and high positive control (HPC) titer acceptable range were also set up as 33.0 ng/mL, 41.0 ng/mL, and 320-1280, respectively. After full validation, both the intra-assay and inter-assay precision testing passed with coefficient of variations (CVs) < 20%. The assay enabled excellent drug tolerance up to 768.0 μg/mL at the HPC level and 291.0 μg/mL at the LPC level, while the tolerance of target interference was up to 74.0 ng/mL of soluble LAG3. Moreover, no false-positive results were observed in the presence of 5% hemolyzed serum samples and 150 mg/dL of triglyceride in the serum samples, no hook effect was observed, and the stability performed normally under room temperature for 24 h, 2-8 °C for 7 d, and six freeze/thaw cycles. In summary, this ADA assay is feasible and could be used for evaluating the immunogenicity of HLX26 in clinical trials.

Abstract
Rabies is a viral disease that is nearly 100% fatal once clinical signs and symptoms develop. Post-exposure prophylaxis can efficiently prevent rabies, and antibody (Ab) induction by vaccination or passive immunization of human rabies immunoglobulin (HRIG) or monoclonal antibodies (mAbs) play an integral role in prevention against rabies. In addition to their capacity to neutralize viruses, antibodies exert their antiviral effects by antibody-dependent cellular cytotoxicity (ADCC), which plays an important role in antiviral immunity and clearance of viral infections. For antibodies against rabies virus (RABV), evaluation of ADCC activity was neglected. Here, we developed a robust cell-based reporter gene assay (RGA) for the determination of the ADCC activity of anti-RABV antibodies using CVS-N2c-293 cells, which stably express the glycoprotein (G) of RABV strain CVS-N2c as target cells, and Jurkat cells, which stably express FcγRⅢa and nuclear factor of activated T cells (NFAT) reporter gene as effector cells (Jurkat/NFAT-luc/FcγRⅢa cells). The experimental parameters were carefully optimized, and the established ADCC assay was systematically validated according to the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Q2 guideline. We also evaluated the ADCC activity of anti-RABV antibodies, including mAbs, HRIG, and vaccine induced antisera, and found that all test antibodies exhibited ADCC activity with varied strengths. The established RGA provides a novel method for evaluating the ADCC of anti-RABV antibodies.

Abstract
Myocardial injury is a common complication of sepsis. MicroRNA (miRNA) miR-214-3p is protective against myocardial injury caused by sepsis, but its mechanism in lipopolysaccharide (LPS)- induced cardiomyocyte injury is still unclear. An AC16 cell injury model was induced by LPS treatment. Cell Counting Kit-8 and flow cytometry assay showed decreased cell viability and increased apoptosis in LPS-treated AC16 cells. The levels of caspase- 3, Bax, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), myosin 6 (Myh6), myosin 7 (Myh7), reactive oxygen species (ROS), and malondialdehyde (MDA) were increased in LPS-treated AC16 cells, but the levels of Bcl-2 and superoxide dismutase (SOD) were decreased. MiR-214-3p was down-regulated and cathepsin B (CTSB) was upregulated in LPS-treated AC16 cells. At the same time, miR-214-3p could target CTSB and reduce its expression. We also found that a miR-214-3p mimic or CTSB silencing could significantly reduce LPSinduced apoptosis, decrease ROS, MDA, caspase-3, and Bax and increase SOD and Bcl-2. CTSB silencing could significantly reduce ANP, BNP, Myh6, and Myh7 in LPS-treated AC16 cells. The effects of CTSB silencing were reversed by a miR-214-3p inhibitor. In summary, miR-214-3p could inhibit LPSinduced myocardial injury by targeting CTSB, which provides a new idea for myocardial damage caused by sepsis.

Abstract
Even though aberrant mechanistic target of rapamycin (mTOR) signaling is known to cause cardiomyopathy, its underlying mechanism remains poorly understood. Because augmentation of αB-crystallin and hspB2 was presented in the cortical tubers and lymphangioleiomyomatosis of tuberous sclerosis complex patients, we deciphered the role of αB-crystallin and its adjacent duplicate gene, hspB2, in hyperactive mTOR-induced cardiomyopathy. Cardiac Tsc1 deletion (T1-hKO) caused mouse mTOR activation and cardiomyopathy. Overexpression of αB-crystallin and hspB2 was presented in the hearts of these mice. Knockout of αB-crystallin/hspB2 reversed deficient Tsc1-mediated fetal gene expression, mTOR activation, mitochondrial damage, cardiomyocyte vacuolar degeneration, cardiomyocyte size, and fibrosis of T1-hKO mice. These cardiac-Tsc1; αB-crystallin; hspB2 triple knockout (tKO) mice had improved cardiac function, smaller heart weight to body weight ratio, and reduced lethality compared with T1-hKO mice. Even though activated mTOR suppressed autophagy in T1-hKO mice, ablation of αB-crystallin and hspB2 failed to restore autophagy in tKO mice. mTOR inhibitors suppressed αB-crystallin expression in T1-hKO mice and rat cardiomyocyte line H9C2. Starvation of H9C2 cells activated autophagy and suppressed αB-crystallin expression. Since inhibition of autophagy restored αB-crystallin expression in starved H9C2 cells, autophagy is a negative regulator of αB-crystallin expression. mTOR thus stimulates αB-crystallin expression through suppression of autophagy. In conclusion, αB-crystallin and hspB2 play a pivotal role in Tsc1 knockout-related cardiomyopathy and are therapeutic targets of hyperactive mTOR-associated cardiomyopathy.

Abstract
Intestinal epithelium serves as the first barrier against the infections and injuries that mediate colonic inflammation. Colorectal cancer is often accompanied with chronic inflammation. Differed from its well-known oncogenic role in many malignancies, we present here that Golgi membrane protein 1 (GOLM1, also referred to as GP73) suppresses colorectal tumorigenesis via maintenance of intestinal epithelial barrier. GOLM1 deficiency in mice conferred susceptibility to mucosal inflammation and colitis-induced epithelial damage, which consequently promoted colon cancer. Mechanistically, depletion of GOLM1 in intestinal epithelial cells (IECs) led to aberrant Notch activation that interfered with IEC differentiation, maturation, and lineage commitment in mice. Pharmacological inhibition of Notch pathway alleviated epithelial lesions and restrained pro-tumorigenic inflammation in GOLM1-deficient mice. Therefore, GOLM1 maintains IEC homeostasis and protects against colitis and colon tumorigenesis by modulating the equilibrium of Notch signaling pathway.

Abstract
Several validated dynamic in vitro models of the colon have been developed for humans, but there is no dynamic in vitro fermentation model for pigs. This study was conducted to modify the human, dynamic, computer-controlled TNO in vitro model of the colon (TIM-2) for pigs and investigate effects of different starch sources and polysaccharides on swine microbiota structure, ecological network, predictive functional profile, and short-chain fatty acids production. Our study showed that three different types of starch or two polysaccharides greatly impacted microbiota composition. Co-occurrence network analysis indicated that microbiota fed with different sources of starch changed the network topological properties. Functional profiles were predicted to vary significantly among the three starch treatments, and the original pig faecal inoculum was more similar to maize starch treatment. On the other hand, compared with maize starch and arabinoxylans (AX), the microbial composition of the original inoculum was more similar when AX-XG (arabinoxylans and xyloglucan) were added, and the functional profile of the original inoculum also clustered with AX-XG. The cumulative production of acetic, propionic, and butyric acid on maize starch were significantly higher than those on potato starch and wheat starch, while only the amount of acetic acid was significant higher on AX-XG than that on AX. In conclusion, supplementation of maize starch as the starch source together with AX and XG, leads to the bacteria being more stable in the in vitro model and closer to the original inoculum and microbial function compared to potato starch, wheat starch and AX. A maize basal diet may improve energy absorption in the large intestine in growing pigs.

Abstract
BACKGROUND Although shown to be safe in infancy, robotic-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction obstruction (UPJO) is most commonly performed in older children and adolescents. OBJECTIVE This study examined a contemporary RALP experience at a single tertiary pediatric center and compared outcomes in infants aged ≤1 year with an older cohort. METHODS AND DESIGN All RALP procedures were entered into an Institutional Review Board-approved data registry from 2012 to 2016. Patients were retrospectively grouped according to age. The primary outcome was success rate. Secondary outcomes included complications and length of hospital stay. Failure was defined as the need for secondary surgical intervention for UPJO or worsening urinary tract dilation on imaging. Statistical analysis was performed using SPSS version 20. Mann-Whitney U testing was used for comparison. RESULTS A total of 138 patients underwent RALP during 2012-2016, with a median age of 6 years (IQR 1, 13.25) and a male:female ratio of approximately 2:1. Of these, 34 (24.6%) were aged ≤1 year. Of all patients, 60 (43.5%) presented with a history of prenatal hydronephrosis, and 32% had a crossing vessel causing obstruction. An indwelling stent was placed in antegrade fashion in 71% of cases, and 18% had a percutaneously placed externalized stent. There were six (4%) failures requiring reoperation. Multivariate and comparative analysis demonstrated that the infant cohort utilized less morphine equivalents and more often had a percutaneous stent placed compared to the older cohort. Of the complications that occurred, 60% were minor (Clavien grades 1 and 2) and 40% were Clavien grade 3 in the infant cohort, and 70.1% and 29.9% in the older cohort, respectively. No studied criteria predicted failure in either cohort. CONCLUSION This study presented one of the largest contemporary series of consecutive pediatric RALPs, and showed an overall success rate of 96%. There were no significant differences in length of hospital stay, and complications or failure rates in infants compared to older children. This study substantiated the ongoing trend towards the adaptation of robotic-assisted surgery for the entire pediatric patient population.

Abstract
INTRODUCTION Previous studies have revealed the relationship between androgen receptor (AR) CAG and/or GGC polymorphisms and risk of cryptorchidism, yet the results have been elusive and controversial. AIM To determine whether AR polymorphic CAG and/or GGC repeats are related to cryptorchidism. STUDY DESIGN The relevant studies were obtained from PubMed, Embase, China National Knowledge Infrastructure, and Wanfang. The pooled odds ratios with 95% confidence intervals (CIs) were used to assess the strength of associations. Subgroup analyses were performed based on ethnicity and source of controls. Moreover, Begg's funnel plots and Egger's linear regression test were conducted to determine publication bias. RESULTS Eight case-control studies containing 321 patients and 784 normal controls were included. There was a significant association between longer CAG repeats and cryptorchidism risk (weighted mean difference (WMD) = 0.62; 95% CIs 0.06, 1.18; P = 0.031). Moreover, there was a significant association between the longer GGC repeats and cryptorchidism risk (WMD = 0.87; 95% CIs 0.04, 1.74; P = 0.040). There was significant association between the longer CAG repeats and bilateral cryptorchidism (WMD = 0.88; 95% CIs -0.18, 1.94; P = 0.011), while there was no significant association between the longer CAG repeats and unilateral cryptorchidism (WMD = -0.09; 95% CIs -0.50, 0.31; P = 0.554). There were significant associations between the longer GGC repeats and unilateral cryptorchidism (WMD = 0.88; 95% CIs -0.30, 2.05; P = 0.005) and bilateral cryptorchidism (WMD = 1.35; 95% CIs -0.52, 3.21; P = 0.000). Stratifying analysis revealed an association between longer CAG/GGC repeats and cryptorchidism in Caucasian populations from Europe (WMD = 0.73; 95% CIs 0.00, 1.46; P = 0.017), while there was no association with Asian populations. DISCUSSION This meta-analysis found that CAG/GGC repeats in the AR gene were longer in cryptorchidism patients compared to controls. Both the longer CAG repeats and GGC repeats in the AR gene were associated with cryptorchidism risk. The longer CAG repeats were associated with bilateral cryptorchidism, whereas the longer GGC repeats were associated with unilateral and bilateral cryptorchidism. Stratifying analysis revealed an association between longer CAG/GGC repeats and cryptorchidism in Caucasian populations from Europe, while there was no association between longer CAG/GGC repeats and cryptorchidism in Asian populations. CONCLUSION The CAG/GGC repeats in the AR gene were longer in cryptorchidism than in controls. Longer CAG repeats may play a role in determining bilateral cryptorchidism, and longer GGC repeats may play a role in determining unilateral and bilateral cryptorchidism. These observations were more applicable to Caucasian populations.

Abstract
OBJECTIVE Urinary retention following robotic-assisted laparoscopic extravesical ureteral reimplantation (RALUR) is proposed to be due to traction or injury of the pelvic parasympathetic nerve plexus during distal ureteral dissection. Nerve-sparing techniques have been employed to avoid injury to the pelvic plexus, either directly or indirectly. This single-center study assessed postoperative urinary retention rates after extravesical RALUR and investigated whether demographic or operative factors could predict this occurrence. METHODS All RALUR cases entered into an Institutional Review Board-approved registry were retrospectively reviewed, and the rate of postoperative retention was determined. Postoperative urinary retention was defined as the need for catheterization at any time in the postoperative period during hospital admission or within 1 week after the operation. This included acute urinary retention episodes (AUR) as well as high post-void residuals (>50% of expected bladder capacity). Univariate analysis was performed to analyze for predictors of postoperative retention. Factors assessed included age, gender, clinical presentation, bowel bladder dysfunction (BBD), pre-operative urinary tract infection (UTI), procedure length, grade of vesicoureteral reflux (VUR), and operative laterality. RESULTS A total of 128 patients underwent extravesical RALUR in 179 ureters during the study period 2012-2016. Male:female ratio was 1:2.6. Median age at surgery was 4 years. Bilateral RALUR was performed in 52 cases (40.6%), and unilateral in 76 (59.4%). Urinary retention requiring catheterization occurred in 11 cases (8.59%). Of these, seven were post-bilateral RALUR, while the remaining four were unilateral. In seven cases, postoperative retention occurred within 24 h following RALUR. The remaining four instances occurred within 1 week, despite successful voiding in the immediate postoperative period. Univariate analysis revealed male gender (P = 0.009) and operating room time (P = 0.029) as predictors of retention. No association was found with age, weight, BBD, pre-operative UTI, grade of VUR, or laterality. CONCLUSION Urinary retention after RALUR was an infrequent complication. When it did occur, urinary retention appeared to be secondary to covariates such as male gender and length of surgical time - possibly an indication of technical difficulty - rather than laterality of repair.

Abstract
BACKGROUND Proliferative vitreoretinopathy (PVR) is a disease caused by dedifferentiation, translocation and proliferation of several types of local cells. These cells form fibrocellular membranes resulting in detachment of retinal and vision loss. PVR occurs in 8%-10% of patients undergoing primary retinal detachment (RD) surgery and becomes a major obstacle for successful RD repair. Retinal pigment epithelial (RPE) cells are among the major cells which consist of fibrocellular membranes. Reproliferation and Epithelial-mesenchymal transition (EMT) are the primary pathological alteration of RPE cells in PVR. METHODS RPE cells were treated with curcumin at different concentrations for 24, 48 and 72 hours. The viable cells were detected by MTT assay. The apoptosis of RPE was stained by Multicaspase/7-AAD and detected using flow cytometry. Cell cycle analysis was quantified by PI staining. The mRNA levels were detected by real-time PCR. The protein levels were detected by western blot. RESULTS We found a compound curcumin significantly inhibited proliferation and EMT of RPE cells in vitro. Further study showed curcumin induced cell cycle arrest by activating G2 checkpoint through p53 pathway. Meanwhile, we found that curcumin suppressed the AKT, MAPK and TGF-β pathways in RPE cells which may also affect proliferation and EMT. Our research identified curcumin a potential novel agent for the PVR prevention and treatment. Curcumin induces cell cycle arrest by activating G2 checkpoint. CONCLUSION Our results in this study also provide the insights to broaden the application of curcumin in research and probably clinics.

Abstract
To evaluate the effect of dietary rapeseed meal (RM) supplementation on cecal trimethylamine and bacteria in laying hens with different flavin-containing monooxygenase 3 (FMO3) genotypes, a 3 × 2 2-factorial arrangement was employed using FMO3 genotypes (AA, AT, and TT) and dietary RM (0 and 14% of diet) as the main effects. At 50 wk of age, 36 hens of AT genotype and 36 hens of TT genotype were randomly allotted to one of the 2 dietary treatments, and each dietary treatment consisted of 3 replicates with 6 birds each. A total of 12 hens with AA genotype were allotted to one of the 2 dietary treatments that consisted of 3 replicates with 2 hens. Hens were fed 0% RM in a corn-soybean (SM) diet for one wk before the 6-week feeding trial period. Dietary RM supplementation increased trimethylamine (TMA) concentrations in both egg yolks (P < 0.0001) and cecal chyme (P < 0.0001). Dietary RM supplementation increased bacterial abundance and diversity (P < 0.0001). Weighted UniFrac, Nonmetric Multidimensional Scaling, and analysis of similarity (R-ANOSIM = 0.1516; P-value = 0.014) indicated distinct clustering was dependent on diets rather than FMO3 genotypes. Twenty-four phyla (most dominant, Bacteroides, Firmicutes, and Proteobacteria) and 229 genera were identified in the cecal samples. Compared with the SM diets, RM diets increased the proportion of Firmicutes (P = 0.004), Proteobacteria (P = 0.006), and Firmicutes:Bacteroides (P = 0.001), and some low-abundance phyla (P < 0.01), whereas the abundance of Bacteroides was lower (P = 0.0002). The abundance of 42 genera varied with dietary types. Six phyla and 35 genera were positively correlated with TMA concentration in the cecal chyme. In conclusion, the major TMA-producing bacteria in cecal were from Firmicutes and Proteobacteria phyla. The major TMA-producing bacterial genera could be from the genera that positively correlated with TMA concentration.

Abstract
In our study, the impact of miR-16-1-3p on cell proliferation and invasion in NSCLC was explored. miR-16-1-3p mimics were transfected to A549 cells for miR-16-1-3p overexpression. qRT- PCR and Western blot were applied to explore the relative expression of mRNA and protein in A549 cells. Furthermore, the cell proliferation capability was determined by MTT assay. Additionally, cell migration and invasion were measured using a scratch assay and transwell assay, respectively. Moreover, TargetScan and luciferase reporter assay was utilized to investigate the target of miR-16-1-3p. The results indicated that miR-16-1-3p was downregulated in NSCLC cells and upregulation of miR-16-1-3p was able to inhibit the expression of TWIST1. In addition, the reduced cell proliferation, inhibited cell migration and invasion were observed in miR-16-1-3p mimic group compared to the negative control group. The luciferase reporter gene showed that TWIST1 was a target of miR-16-1-3p. Therefore, the present study demonstrated that miR-16-1-3p may suppress A549 cell proliferation, migration and invasion by targeting TWIST1. Thus, miR-16-1-3p might play important roles in NSCLC development, which provides a novel aspect for NSCLC investigation (Fig. 6, Ref. 26).

Abstract
Feral pigs (Sus scrofa) are an invasive species widely distributed throughout North and South America, as well as Australia. Feral pigs frequently destroy farm fields, causing $1.5 billion in damage annually in the United States alone. These pigs are known carriers of over 30 diseases, thereby posing a threat to livestock and public health. Current control methods are ineffective due to high fecundity rates. An orally consumed contraceptive bait may be effective, but currently none exists for pigs. In rats, an orally consumed contraceptive that affects both male and females has shown considerable promise. This bait contains 2 active ingredients: triptolide, a diterpenoid diepoxide isolated from the Chinese medicinal plant Tripterygium wildfordii, and 4-vinylcyclohexene diepoxide (VCD), an industrial chemical. Triptolide prevents ovarian follicle maturation and disrupts spermatogenesis; VCD acts in the female to cause premature ovarian failure and, in one report, disrupt male mouse spermatogenesis. There are no studies reported for these active ingredients on boar spermatogenesis. A proprietary pig bait has been developed containing these 2 ingredients and was fed to commercial (com.) and Sinclair (sin.) boars (com. n = 3, sin. n = 3) for 15 consecutive days to evaluate changes in reproductive parameters. Boars were given 250 g of bait twice daily that contained 0.25 mg of triptolide and 1.55 mM of VCD. Ejaculates were collected from boars before, during, and after the treatment period (Day 0, 7, 15, 30, 37, 45, and 60) and were evaluated for possible impacts on fertility. Ejaculates were able to be collected from 4 of 6 boars (com. n = 2, sin. n = 2). Previous studies indicate triptolide acts during the differentiation phase of spermatogenesis, suggesting a delayed onset of perturbation allowing for comparison of semen collected early in the study (Day 0, 7, and 15) to post-treatment samples. Progressive motility (PM) was rated on a 1 to 5 scale. Plasma testosterone and testes volume were also monitored at these time points. Statistical analysis was performed using Kruskal–Wallis test. No significant differences were found in plasma testosterone, testes volume, or sperm concentration. No significant differences in viability, morphology, or PM were found at Day 0, 7, or 15. However, differences (P < 0.05) were observed in semen parameters at Day 37 and 45 in comparison to D0, 7, and 15. The percentage of sperm with normal morphology at treatment Day 37 (3.3%) and 45 (3.3%) was lower than at Day 0, 7, and 15 (72.3%, P < 0.05). Differences (P < 0.05) were also found in viability at Day 37 (13.3%) and 45 (8%) in comparison to Day 0, 7, and 15 (71.6%). Differences were also found in PM at Day 37 (0.33) and 45 (1) in comparison to Day 0, 7, and 15 (4.8). These results suggest an impact on spermatogenesis, specifically spermiogenesis, suggesting a decrease in fertility due to lower quality of spermatozoa. Further studies are needed to evaluate the bait’s impact on feral pig reproduction.

Abstract
The myostatin gene or growth differentiation factor 8 is a member of the transforming growth factor-β superfamily that acts as a negative regulator of muscle growth. Mutations inactivating this gene occur naturally in Piedmontese and Belgian Blue cattle breeds, resulting in a dramatic increase in muscle mass, albeit with unwanted consequences of increased dystocia and decreased fertility. Modulation of muscle mass increase without the unwanted effects would be of great value for improving livestock growth and economic value of livestock. The objective of our work was to use the CRISPR-Cas9 genetic engineering tool to generate deletions of different elements in the myostatin promoter in order to decrease the level of expression and obtain an attenuated phenotype without the detrimental consequences of an inactivating mutation. To achieve this objective 4 different small guide RNA (sgRNA) targeting the promoter near the mutation were designed with PAM positions from transcription starting site of −1577, −689, −555, and −116. These sgRNA were cloned individually into the Cas9 plasmids (px461, and px462; Addgene®). These plasmids allow for a dual puromycin resistance (px462) and green fluorescent protein (px461) selection. We first tested the functionality of these sgRNA in vitro by co-transfecting bovine fetal fibroblasts with a combination of both plasmids (Set 1 = sgRNA 1–4; Set 2 = sgRNA 2–3). Cells were exposed to puromycin (0.2 µg mL−1) for 72 h, then single and mixed colonies positive for green fluorescent protein expression were separated for propagation. The DNA was extracted for PCR amplification of the targeted region. Multiple deletions and a few insertion events were observed after PCR, bands were cloned into TOPO® vector (Thermo Fisher Scientific, Waltham, MA, USA) and sequenced. Sequencing results confirmed the PCR products as insertions or deletions in the myostatin promoter region. We proceeded to modify the myostatin promoter directly in bovine zygotes. For this, IVF-derived zygotes were randomly assigned to 3 different treatment groups Set 1, Set 2, or Null (no sgRNA) for microinjections. Each zygote was injected with ~100 pL of trophectoderm buffer containing 50 ng µL−1 of total sgRNA, 10 ng µL−1 of Cas9 mRNA, and 30 ng µL−1 of Cas9 protein with 1 mg mL−1 of fluorescent dextran. Day 7 post-IVF blastocysts were lysed and DNA was extracted for PCR amplification of the target region. In Set 1, 16 of 19 embryos (94.12%) were successfully edited, whereas in Set 2 there were 11 of 17 embryos (64.7%) edited. In both sets of sgRNA there was a high degree of mosaicism, with only 1 embryo demonstrating a homozygous deletion. In conclusion, CRISPR/Cas9 acts over the course of the first few cleavage divisions Further research is necessary to refine the CRISPR/Cas9 system for inducing genetic mutations in bovine embryos.

Abstract
Protein-protein interactions can regulate different cellular processes, such as transcription, translation, and oncogenic transformation. The split Renilla luciferase complementation assay (SRLCA) is one of the techniques that detect protein-protein interactions. The SRLCA is based on the complementation of the LN and LC non-functional halves of Renilla luciferase fused to possibly interacting proteins which after interaction form a functional enzyme and emit luminescence. The BGLF4 of Epstein-Barr virus (EBV) is a viral protein kinase that is expressed during the early and late stages of lytic cycles, which can regulate multiple cellular and viral substrates to optimize the DNA replication environment. The heat shock protein Hsp90 is a molecular chaperone that maintains the integrity of structure and function of various interacting proteins, which can form a complex with BGLF4 and stabilize its expression in cells. The interaction between BGLF4 and Hsp90 could be specifically detected through the SRLCA. The region of aa 250-295 of BGLF4 is essential for the BGLF4/Hsp90 interaction and the mutation of Phe-254, Leu-266, and Leu-267 can disrupt this interaction. These results suggest that the SRLCA can specifically detect the BGLF4/Hsp90 interaction and provide a reference to develop inhibitors that disrupt the BGLF4/Hsp90 interaction.

Abstract
Black locust (Robinia pseudoacacia) is a tree in the subfamily Faboideae, native to North America, that has been naturalized and widely planted in temperate Europe and Asia. Black locust has important ecological and economic value, but its quality needs improvement. Hybridization programs are important for black locust breeding, but the low rate of fruit set after controlled pollination limits both its breeding and that of other monoclinous plant species that share this problem. In this study, we investigated gene expression in emasculated black locust flowers using the cDNA-amplified fragment length polymorphism technique to determine why the rate of fruit set is low after controlled pollination. Flowers that were emasculated after being frozen in liquid nitrogen were used as controls. Changes in the flower transcriptome were more dramatic at 5 h after emasculation than at 48 h. Injury caused by emasculation decreased the expression levels of genes associated with metabolism, growth regulation, signal transduction, and photosynthesis, and it increased the expression of genes related to stress-response metabolism, signal transduction, and promotion of senescence. The changes in the expression levels of these genes had negative effects on sugar metabolism, protein metabolism, lipid metabolism, energy metabolism, matter transport, signal transduction, osmotic regulation, pH regulation, and photosynthesis. Thus, emasculation accelerated flower senescence, resulting in low fruit set.

Abstract
Periplaneta americana cockroach is an important source of inhalant indoor allergen resource, and there are more than twenty IgE-binding components identified in P. americana, but only nine allergens were characterized. Our knowledge about cockroach allergens remains poor. In this work, two novel allergen proteins Per a 11 (alpha-amylase) and Per a 12 (chitinase) with molecular weight around 55 and 45 kDa, respectively, were purified and characterized from the midgut of cockroaches. Their primary sequences were determined by Edman degradation, mass spectrometry, and cDNA cloning. Sera from 39 and 30 of 47 (83.0% and 63.8%) patients reacted to Per a 11 and Per a 12 on immunoblots, respectively. The allergenicity of Per a 11 and Per a 12 was further confirmed by competitive ELISA, basophil activation test (BAT), and skin prick test (SPT). They appear to be of importance for the allergic reactions induced by cockroach and have a potential for component-based diagnosis of allergy.

Abstract
OBJECTIVE Due to the weak ascending aorta, it is extremely challenging to establish an anterograde selective cerebral perfusion (ASCP) model in rabbits, especially when cardioplegic arrest is required. Herein, the aim of this study was to establish a rabbit ASCP model with cardiac arrest being easily performed and being similar to the clinical scenario. MATERIALS AND METHODS Twenty-two adult New Zealand white rabbits were selected for ASCP model establishment and another 22 rabbits were utilized for blood donation. The cardiopulmonary bypass (CPB) circuit consisted of a roller pump, a membrane oxygenator, a heat-cooler system and a blood reservoir, which were connected by silicone tubing. The total priming volume of the circuit was 70 ml. Cannulations on the right and left subclavian arteries were used for arterial inflow and cardioplegia perfusion, respectively. Venous drainage was conducted through the right atrial appendage. ASCP was initiated by clamping the innominate artery; the flow rate was maintained 10 ml/kg/minute and sustained for 60 minutes. After 120 minutes of reperfusion, the rabbits were sacrificed. The mean arterial pressure, heart rate, electrocardiogram and urine output were monitored. Arterial blood samples were analyzed at the following time points: after anesthesia, immediately after CPB, after aorta cross-clamping and cardioplegia perfusion, 5 min after the re-opening of the aorta and at CPB termination. RESULTS ASCP modeling was performed successfully on 18 rabbits and 4 rabbits unsuccessfully. Vital signs and blood gas indictors changed in an acceptable range throughout the experiments. One rabbit had ventricular fibrillation after re-opening of the ascending aorta. Obvious hemodilution occurred after the perfusion of cardioplegia, but the hematocrit improved after CPB termination. CONCLUSION By using cannulation of the subclavian artery rather than the aorta and with a low priming volume, we established a modified rabbit model of ASCP with cardioplegic arrest. The model has excellent repeatability and operability, which is similar to the clinic process and is suitable for the study of cerebral, cardiac and renal protection.

Abstract
OBJECTIVE To investigate the volume of intracranial structures in fetuses with congenital heart disease (CHD). METHODS Total intracranial volume, frontal lobes volume, thalamus volume and cerebellar volume were prospectively evaluated and compared in 73 fetuses with CHD and 168 normal fetuses using three-dimensional ultrasound combined with post-processing software at 20 + 0 to 36 + 6 weeks of gestation. Multiple regression analyses were performed to identify risk factors for reduced volume of intracranial structures. RESULTS From the 28th week of gestation onwards, total brain volumes and those of specific structures became progressively smaller in fetuses with CHD relative to those in controls (P < 0.05). The decrease was largest in frontal lobes volume, followed by total intracranial volume and cerebellar volume, and the smallest decrease was in thalamus volume (P < 0.05). Multivariable analysis showed that the diagnostic category (P < 0.001) was independently associated with smaller brain volumes in fetuses with CHD. The largest differences from controls occurred in hypoplastic left heart syndrome (HLHS), followed by aortic hypoplasia, transposition of the great arteries (TGA) and tetralogy of Fallot (TOF). CONCLUSIONS The volume of intracranial structures is smaller in fetuses with CHD, particularly in those with HLHS, aortic hypoplasia or TGA. This study highlights the need for routine brain screening and early intervention to improve neurodevelopmental outcomes in fetuses with CHD.

Abstract
BACKGROUND In the pig-to-nonimmunosuppressed baboon artery patch model, a graft from an α1,3-galactosyltransferase gene-knockout pig transgenic for human CD46 (GTKO/CD46) induces a significant adaptive immune response (elicited anti-pig antibody response, increase in T cell proliferation on MLR, cellular infiltration of the graft), which is effectively prevented by anti-CD154mAb-based therapy. METHODS As anti-CD154mAb is currently not clinically applicable, we evaluated whether it could be replaced by CD28/B7 pathway blockade or by blockade of both pathways (using belatacept + anti-CD40mAb [2C10R4]). We further investigated whether a patch from a GTKO/CD46 pig with a mutant human MHC class II transactivator (CIITA-DN) gene would allow reduction in the immunosuppressive therapy administered. RESULTS When grafts from GTKO/CD46 pigs were transplanted with blockade of both pathways, a minimal or insignificant adaptive response was documented. When a GTKO/CD46/CIITA-DN graft was transplanted, but no immunosuppressive therapy was administered, a marked adaptive response was documented. In the presence of CD28/B7 pathway blockade (abatacept or belatacept), there was a weak adaptive response that was diminished when compared with that to a GTKO/CD46 graft. Blockade of both pathways prevented an adaptive response. CONCLUSION Although expression of the mutant MHC CIITA-DN gene was associated with a reduced adaptive immune response when immunosuppressive therapy was inadequate, when blockade of both the CD40/CD154 and CD28/B7 pathways was present, the response even to a GTKO/CD46 graft was suppressed. This was confirmed after GTKO/CD46 heart transplantation in baboons.

Abstract
OBJECTIVE Blood and crystalloid cardioplegia are the main myocardial protective solutions used in pediatric cardiac surgery. However, the effectiveness of these two solutions on myocardial metabolism, reperfusion injury and clinical outcomes in pediatric patients is still under debate. The purpose of this meta-analysis was to compare the efficacy of these two cardioplegia solutions in pediatric cardiac surgery. METHODS Keyword searches were performed on PUBMED, EMBASE and The Cochrane Library for randomized, controlled, clinical studies which were primarily comparing blood and crystalloid cardioplegia in pediatric cardiac surgery and provided data of postoperative cardiac troponin I (cTnI), lactate, mechanical ventilation time, length of intensive care unit (ICU) stay and inotropic support. Databases were searched from 1966 to June 2013 and were restricted to peer-reviewed English language publications of human subjects. We summarized the combined results of the data as mean difference (MD, when outcome measurements were made on the same scale) or standard mean difference (SMD, when the studies assess the same outcome with different scales), with 95% confidence intervals. RESULTS Five studies were identified, with a total of 323 patients. Lactate level after cardiopulmonary bypass (CPB) was significantly lower after blood cardioplegia compared with crystalloid cardioplegia (SMD 1.09, 95%CI 0.12 to 2.06, p=0.03); cTnI release postoperatively at 4-6 h (MD 0.92 ng/ml, 95%CI -0.13 to 1.97, p=0.09), 12 h (MD 0.2 ng/ml, 95% CI -0.43 to 0.84, p=0.53) and 24 h (MD 0.98 ng/ml, 95%CI -0.26 to 2.22, p=0.12) was not significantly different between the groups; ventilation duration (MD 5.15 hours, 95%CI -7.51 to 17.81, p=0.42) and length of ICU stay (SMD -0.3, 95%CI -0.80 to 0.21, p=0.25) were not significantly different between the groups either. CONCLUSION Myocardial metabolism was better in the blood cardioplegia group compared with the crystalloid cardioplegia group. However, there was no evidence of improvement in myocardial damage or clinical outcome for either cardioplegia solution.

Abstract
PURPOSE The aim of the study was to investigate rapid prototyping technology for the production of patient-specific, cost-effective liquid fillable phantoms directly from patient CT data. METHODS Liver, spleen, and kidney volumes were segmented from patient CT data. Each organ was converted to a shell and filling holes and leg supports were added using computer aided design software and prepared for printing. Additional fixtures were added to the liver to allow lesion inserts to be fixed within the structure. Phantoms were printed from an ultraviolet curable photopolymer using polyjet technology on an Objet EDEN 500V 3D printer. RESULTS The final print material is a clear solid acrylic plastic which is watertight, rigid, and sufficiently durable to withstand multiple assembly and scanning protocols. Initial scans of the phantoms have been performed with Tc-99m SPECT and F-18 PET/CT. CONCLUSIONS The organ geometry showed good correspondence with anatomical references. The methodology developed can be generally applied to other anatomical or geometrical phantoms for molecular imaging.

Abstract
Objective: Although fresh frozen plasma (FFP) is one of the most commonly used hemostatic agents in clinical specialties today, there is little evidence available supporting its administration. Our present study observed the effects of a priming strategy without FFP during cardiopulmonary bypass (CPB) on postoperative coagulation and clinical recovery in pediatric patients, aiming to supply new evidence for evidence-based use of FFP. Method: Eighty pediatric patients with congenital heart disease undergoing cardiac surgery with CPB were randomized to receive either 10-20 ml/kg 4% succinylated gelatin (Gelofusine, GEL group, n = 40) or 1-2 units FFP (FFP group, n = 40) in the pump prime. Rapid-thromboelastography (r-TEG) and functional fibrinogen level were measured before skin incision and 15 minutes after heparin reversal. We recorded the volume of chest tube drainage, transfusion requirements and the dosage of pharmacological agents. The ventilation time, ICU length of stay and hospitalization time after surgery were also collected. Results: After heparin neutralization, there were significantly elevated levels of fibrinogen in the FFP group, which were manifested by r-TEG parameters MAf and FLEV. No significant differences were observed between the two groups in postoperative bleeding, transfusion requirements and the usage of pharmacological agents. Recovery time was also comparable between the two groups. Conclusion: In conclusion, prophylactic use of FFP in the priming solution does not provide clinical benefits as presumed. Artificial colloids, such as Gelofusine, can be used safely and effectively as a substitute for FFP in the pump prime. TEG is an effective assessment tool to evaluate postoperative coagulation function in pediatric patients.

Abstract
BACKGROUND Selective inhibition of inward rectifier K+ channels could abolish the protection mediated by ischemic preconditioning, but the roles of these channels in ischemic postconditioning have not been well characterized. Our study aims to evaluate the effect of inward rectifier K+ channels on the protection induced by ischemic postconditioning. METHODS Langendorff-perfused rat hearts (n=8 per group) were split into four groups: postconditioning hearts (IPO group); ischemic postconditioning with BaCl2 hearts (PB group); ischemic postconditioning with zacopride hearts (PZ group); and without ischemic postconditioning (CON group). After suffering 30 minutes of global ischemia, groups IPO, PB and PZ went through 10 seconds of ischemic postconditioning with three different perfusates: respectively, Krebs-Henseleit buffer (IPO group); 20 μmol/L BaCl2 (antagonist of the channel, PB group); 1 μmol/L zacopride (agonist of the channel, PZ group). RESULTS At the end of reperfusion, the myocardial performance was better preserved in the PZ group than the other three groups. The PB group showed no significant differences from the CON group. CONCLUSIONS Our study has shown that the IK1 channel agonist zacopride is associated with the enhancement of ischemic postconditioning.
