Abstract
OBJECTIVE To explore the influences of micro ribonucleic acid (miR)-204 on the rats with diabetic retinopathy by regulating the expressions of B-cell lymphoma 2 (Bcl-2) and sirtuin 1 (SIRT1). MATERIALS AND METHODS A total of 36 Sprague-Dawley rats were randomly assigned into normal group (n=12), model group (n=12), and miR-204 mimics group (n=12). No treatment was performed in the normal group, the diabetic retinopathy model was established in model group, and miR-204 mimics were administered for intervention after modeling in the inhibitor group. After 7 d, materials were sampled for detection. The expressions of Bcl-2 and SIRT1 were detected via immunohistochemistry, and their relative protein expression levels were determined via Western blotting (WB). Quantitative Polymerase Chain Reaction (qPCR) was performed to detect the expression of miR-204, and the content of inflammatory factors interleukin (IL)-6, IL-18, and tumor necrosis factor-α (TNF-α) was measured using enzyme-linked immunosorbent assay (ELISA). Finally, cell apoptosis was evaluated via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). RESULTS Immunohistochemistry results showed that the positive expression levels of Bcl-2 and SIRT1 were substantially lower in the model and miR-204 mimics groups than those in the normal group (p<0.05), and their positive expression levels in miR-204 mimics group were notably higher than those in model group (p<0.05). According to Western blot (WB) results, the relative protein expression levels of Bcl-2 and SIRT1 markedly declined in the other two groups compared with those in the normal group (p<0.05), while miR-204 mimics group exhibited remarkably higher relative protein expression levels of Bcl-2 and SIRT1 than the model group (p<0.05). The results of qPCR revealed that the relative expression level of miR-204 was markedly lowered in model and miR-204 mimics groups compared with that in the normal group (p<0.05), and its relative expression level in miR-204 mimics group was remarkably higher than that in the model group. It was found through enzyme-linked immunosorbent assay (ELISA) that compared with normal group, the other two groups had substantially increased content of IL-6, IL-18, and TNF-α (p<0.05), and the content of IL-6, IL-18, and TNF-α in miR-204 mimics group was markedly lower than that in the model group (p<0.05). According to TUNEL results, the apoptosis rate of cells rose substantially in the other two groups compared with that in the normal group (p<0.05), while was notably lower in the miR-204 mimics group than that in the model group (p<0.05). CONCLUSIONS MiR-204 up-regulates Bcl-2 and SIRT1 expressions to inhibit the inflammation and cell apoptosis in rats with diabetic retinopathy.

Abstract
CKB3 is a regulatory (beta) subunit of CK2. In this study Arabidopsis thaliana homozygous T-DNA mutant ckb3 was studied to understand the role of CKB3 in abscisic acid (ABA) signaling. The results shown: CKB3 was expressed in all organs and the highest expression in the seeds, followed by the root. During seed germination and root growth the ckb3 mutant showed reduced sensitivity to ABA. The ckb3 mutant had more stomatal opening and increased proline accumulation and leaf water loss. The expression levels of number of genes in the ABA regulatory network had changed. This study demonstrates that CKB3 is an ABA signaling-related gene and may play a positive role in ABA signaling.

Abstract
Abstract
A collaborative study of a rapid method for the determination of deoxynivalenol (DON) in winter wheat was successfully completed. The method involves sample extraction with acetonitrile-water (84 + 16), cleanup using a disposable column of charcoal, Celite, and alumina, and detection by thin layer chromatography after spraying with an aluminum chloride solution. Each of the 15 collaborators analyzed 12 samples, 2 of which were naturally contaminated, and 10 to which DON was added, in duplicate, at levels of 0,50,100,300, and 1000 ng/ g. Average recoveries of DON ranged from 78 to 96% with repeatabilities of 30-64% and reproducibilities of 33-87%. The results of the study show that false positives were not a problem and that all of the analysts could detect DON at the 300 ng/g level or higher. The method has been adopted official first action.

Abstract
During infectious disease outbreaks, the centers for disease control need to monitor particular areas. Considerable effort has been invested in the development of portable, user-friendly, and cost-effective systems for point-of-care (POC) diagnostics, which could also create an Internet of Things (IoT) for healthcare via a global network. However, at present IoT based on a functional POC instrument is not available. Here we show a fast, user-friendly, and affordable IoT system based on a miniaturized polymerase chain reaction device. We demonstrated the system's capability by amplification of complementary deoxyribonucleic acid (cDNA) of the dengue fever virus. The resulting data were then automatically uploaded via a Bluetooth interface to an Android-based smartphone and then wirelessly sent to a global network, instantly making the test results available anywhere in the world. The IoT system presented here could become an essential tool for healthcare centers to tackle infectious disease outbreaks identified either by DNA or ribonucleic acid.

Abstract
CRISPR-Cas systems have revolutionized genome editing across a broad range of biotechnological endeavors. Many CRISPR-Cas nucleases have been identified and engineered for improved capabilities. Given the modular structure of such enzymes, we hypothesized that engineering chimeric sequences would generate non-natural variants that span the kinetic parameter landscape, and thus provide for the rapid selection of nucleases fit for a particular editing system. Here, we design a chimeric Cas12a-type library with approximately 560 synthetic chimeras, and select several functional variants. We demonstrate that certain nuclease domains can be recombined across distantly related nuclease templates to produce variants that function in bacteria, yeast, and human cell lines. We further characterize selected chimeric nucleases and find that they have different protospacer adjacent motif (PAM) preferences and the M44 chimera has higher specificity relative to wild-type (WT) sequences. This demonstration opens up the possibility of generating nuclease sequences with implications across biotechnology.

Abstract
Objective: To analyze the pathological features of pseudomyxoma peritonei (PMP) in correlation with the survival status and independent prognostic factors. Methods: One-hundred and fifty-five PMP specimens were collected at Beijing Shijitan Hospital, Capital Medical University, from 2012 to 2018. Conventional histopathological evaluation was performed to document the primary tumor site, histopathological type, lymph nodes metastasis, tumor emboli in the blood and lymph vessels, nerve invasion and cellular density. The immunohistochemical parameters including Ki-67, p53, MMR-related protein, MUC2 and MUC5AC were analyzed. Clinical follow-up data were reviewed to correlate with pathological prognostic factors using Kaplan-Meier estimator and Cox proportional hazards regression model for univariate and multivariate analysis. Results: Among 155 PMP patients, there were 77 males and 78 females. There were 98 cases (63.2%) of low-grade peritoneal mucinous carcinomatosis, 49 cases (31.6%) of high-grade peritoneal mucinous carcinomatosis, 8 cases (5.2%) of high-grade mucinous carcinoma peritonei with signet ring cells; only 15 cases (9.7%) with lymph node metastasis; 18 cases (11.6%) with tumor emboli in the blood and lymph vessels; 8/126 (6.3%) were positive dMMR; 100 cases (64.5%) had Ki-67 label index <50%, and 56 cases(36.1%) presented with mutant type p53. Univariate analysis revealed 11 survival-related pathological parameters including gender, age, primary tumor site, histopathological type, lymph node metastasis, tumor emboli in the blood and lymph vessels, nerve invasion, cellular density, Ki-67 label index rate, p53 and dMMR. Multivariate analysis identified 4 independent prognostic factors including the histopathological type (HR 59.78, P<0.01), lymph node metastasis (HR 3.74, P=0.028), nerve invasion (HR 7.81, P=0.007) and dMMR (HR 9.82, P<0.01). Conclusions: Histopathological type is the most important prognostic factor of PMP with dMMR as an independent molecular prognostic indicator.

Abstract
Nucleic acid amplification for the detection of infectious diseases, food pathogens, or assessment of genetic disorders require a laboratory setting with specialized equipment and technical expertise. Isothermal deoxyribonucleic acid amplification methods, such as loop-mediated isothermal amplification (LAMP), exhibit characteristics ideal for point-of-care (POC) applications, since their instrumentation is simpler in comparison with the standard method of polymerase chain reaction. Other key advantages of LAMP are robustness and the production of pyrophosphate in the presence of the target gene, enabling to detect the reaction products using the naked eye. Polymerase inhibitors, presented in clinical samples, do not affect the amplification process, making LAMP suitable for a simple sample-to-answer diagnostic systems with simplified sample preparation. In this review, we discuss the trends in miniaturized LAMP techniques, such as microfluidic, paper-based, and digital with their advantages and disadvantages, especially for POC applications alongside our opinion of the future development of miniaturized LAMP. Introduction of loop mediated isothermal amplification (LAMP) and its principle. Classical microfluidics-based LAMP for DNA/RNA detection. Paper-based LAMP. Microfluidic-based digital LAMP. Future of microfluidic LAMP development.

Abstract
Our goal is an office-based, handheld ultrasound system to target, detach, break, and/or expel stones and stone fragments from the urinary collecting system to facilitate natural clearance. Repositioning of stones in humans (maximum 2.5 MPa, and 3-second bursts) and breaking of stones in a porcine model (maximum 50 cycles, 20 Hz repetition, 30 minutes, and 7 MPa peak negative pressure) have been demonstrated using the same 350-kHz probe. Repositioning in humans was conducted during surgery with a ureteroscope in the kidney to film stone movement. Independent video review confirmed stone movements (≥ 3 mm) in 15 of 16 kidneys (94%). No serious or unanticipated adverse events were reported. Experiments of burst wave lithotripsy (BWL) effectiveness on breaking human stones implanted in the porcine bladder and kidney demonstrated fragmentation of 8 of 8 stones on post mortem dissection. A 1-week survival study with the BWL exposures and 10 specific-pathogen-free pigs, showed all findings were within normal limits on clinical pathology, hematology, and urinalysis. These results demonstrate that repositioning of stones with ultrasonic propulsion and breaking of stones with BWL are safe and effective.

Abstract
Objective: To investigate whether there were differences between the three stains for eosinophil counting in nasal polyps. Method: Three serial sections of formalin-fxed, paraffn-embedded tissues of 23 cases of nasal polyps were stained with Congo red,Chromotrope 2R and conventional HE staining, respectively. The stained sections were converted to digital pathology using a digital slice scanner. The qualitative assessment of the staining results was made in terms of specificity, contrast and background staining. Eosinophils were quantitatively evaluated and statistically analyzed using the Image J Analysis System and GraphPad Prism 5 statistical software. Result: Congo red staining and Chromotrope 2R staining were more specific than conventional HE staining. Chromotrope 2R had the lowest background staining. The majority of Congo red staining (n=20) was lighter in the background than in the conventional HE, while a small number of cases (n=3) background staining slightly stronger. Both Congo red staining and Chromotrope 2R staining had statistically significant differences compared with conventional HE staining (P<0.05), but there was no significant difference between Congo red staining and Chromotrope 2R staining (P>0.05). Conclusion: Congo red staining and Chromotrope 2R staining are more suitable for accurate counting of eosinophils, and the use of these two methods contributes to the harmonization of eosinophil count criteria in the ECRSwNP definition.

Abstract
Identifying the degree of liver inflammation is critical for therapeutic judgement of patients with chronic hepatitis B (CHB). However, we lack indexes which can accurately predict significant liver inflammation in patients with CHB. This study aimed to develop a simple predictive index for liver inflammation in CHB using routine clinical parameters. A total of 519 patients with CHB who underwent liver biopsy were enrolled and randomly divided into training (n = 346) and validation cohorts (n = 173). Based on routine clinical parameters, gamma-glutamyl transpeptidase (GGT; P = 0.031) and platelets (PLT; P < 0.001) were identified as independent predictors of significant inflammation by multivariable analysis in the training cohort. Accordingly, the GGT to PLT ratio (GPR) was developed to amplify the opposing effects for predicting liver inflammation. In the training cohort, the AUCs of GPR in predicting significant inflammation were 0.791 (95% CI: 0.742-0.839), 0.783 (95% CI: 0.717-0.849) and 0.791 (95% CI: 0.716-0.867) in the entire patients with CHB, HBeAg-positive CHB patients and HBeAg-negative CHB patients, respectively. The diagnostic performance of GPR for significant inflammation was significantly superior to that of alanine aminotransferase (ALT), aspartate transaminase (AST) and GGT in all patients with CHB and HBeAg-positive CHB patients, but was comparable with ALT, AST and GGT in HBeAg-negative CHB patients. In the validation cohort, the diagnostic performance of GPR in assessing significant liver inflammation was also superior to other indexes in all patients with CHB and HBeAg-positive CHB patients, but was comparable with GGT in HBeAg-negative CHB patients. Thus, GPR can be a novel and simple index for predicting significant liver inflammation in CHB, especially for HBeAg-positive CHB.

Abstract
Bipolar disorder (BPD), schizophrenia (SCZ) and unipolar major depressive disorder (MDD) are primary psychiatric disorders sharing substantial genetic risk factors. We previously reported that two single-nucleotide polymorphisms (SNPs) rs2709370 and rs6785 in the cAMP responsive element-binding (CREB)-1 gene (CREB1) were associated with the risk of BPD and abnormal hippocampal function in populations of European ancestry. In the present study, we further expanded our analyses of rs2709370 and rs6785 in multiple BPD, SCZ and MDD data sets, including the published Psychiatric Genomics Consortium (PGC) genome-wide association study, the samples used in our previous CREB1 study, and six additional cohorts (three new BPD samples, two new SCZ samples and one new MDD sample). Although the associations of both CREB1 SNPs with each illness were not replicated in the new cohorts (BPD analysis in 871 cases and 1089 controls (rs2709370, P=0.0611; rs6785, P=0.0544); SCZ analysis in 1273 cases and 1072 controls (rs2709370, P=0.230; rs6785, P=0.661); and MDD analysis in 129 cases and 100 controls (rs2709370, P=0.114; rs6785, P=0.188)), an overall meta-analysis of all included samples suggested that both SNPs were significantly associated with increased risk of BPD (11 105 cases and 51 331 controls; rs2709370, P=2.33 × 10-4; rs6785, P=6.33 × 10-5), SCZ (34 913 cases and 44 528 controls; rs2709370, P=3.96 × 10-5; rs6785, P=2.44 × 10-5) and MDD (9369 cases and 9619 controls; rs2709370, P=0.0144; rs6785, P=0.0314), with the same direction of allelic effects across diagnostic categories. We then examined the impact of diagnostic status on CREB1 mRNA expression using data obtained from independent brain tissue samples, and observed that the mRNA expression of CREB1 was significantly downregulated in psychiatric patients compared with healthy controls. The protein-protein interaction analyses showed that the protein encoded by CREB1 directly interacted with several risk genes of psychiatric disorders identified by GWAS. In conclusion, the current study suggests that CREB1 might be a common risk gene for major psychiatric disorders, and further investigations are necessary.

Abstract
Objective: To evaluate the clinical characteristics and preoperative predictive factors in patients with parathyroid carcinoma. Methods: From January 2010 to December 2016, 150 patients with pathologically and biochemically confirmed primary hyperparathyroidism were enrolled in this study. The clinical data were reviewed to define 28 cases of parathyroid hyperplasia, 14 cases of parathyroid carcinoma (PC), and 108 cases of parathyroid adenoma (PA). The clinical characteristics between PC and PA group were compared and analyzed to explore predictive factors for PC. Results: Patients in PC group were significantly younger than those in PA group (47.9±13.9 vs 57.2±14.6 years, P=0.026). The diameter of tumor in PC group was larger than that in PA group (3.6±1.8 vs 2.2±1.4 cm, P=0.005). The levels of albumin-corrected serum calcium, parathyroid hormone (PTH), and alkaline phosphatase (AKP) were all higher in PC group than those in PA group (3.4±0.6 vs 2.9±0.3 mmol/l; 1 157.1 vs 201.6 pg/ml; 168 vs 97 IU/L; all P<0.05). PC correlated with age(r=-0.241, P=0.007), albumin-corrected serum calcium (r=0.324, P<0.001), PTH levels (r=0.301, P=0.001), serum AKP (r=0.217, P=0.019) and tumor size(r=0.238, P=0.011). Receiver operator characteristic curve analysis showed that the optimum cut-off values as follows: albumin-corrected serum calcium 3.15 mmol/L, serum PTH concentration 1 011 pg/ml and tumor diameter 3.35 cm. These indicators can be helpful in the preoperative diagnosis of PC. Conclusions: Patients with PC were younger than the patients with PA. Albumin-corrected serum calcium, serum PTH concentration, and tumor diameter can be helpful in preoperative diagnosis of PC.

Abstract
Abstract
Previous studies have shown that enhancing injection pressure can help improve the precision and mechanical properties of molding products, and reduce their shrinkage. But for now the ordinary hydraulic injection molding machine cannot generally meet the requirements of high pressure injection. To improve the injection pressure, the pressurizing module and the hydraulic circuit were designed, and their influence on the product quality was explored via molding experiments. The relationship between the system pressure of injection molding machine and the injection pressure was demonstrated. The experimental results showed that the maximum injection pressure of the injection molding machine with the pressurizing module was improved from 204 MPa to 320 MPa, up 56.86 %. The lack of materials, bubbles, sags of products were gradually weakened until finally disappeared with increasing the injection pressure. The pressurizing module was convenient to be assembled into or removed from the injection molding machine without damaging the original structure, and the state of pressurizing or no pressurizing could be transformed easily during the injection molding process. These results indicated that this technology was easy to be popularized and applied.

Abstract
OBJECTIVE The incidence of rectal carcinoma (RC) has been increasing recently, and becomes the second most common digestive tumors besides gastric cancer, with a rise in the incidence of RC in younger populations. The early diagnosis and treatment are thus critical for the improvement of survival rate and life quality of patients. Stomatin-like protein 2 (SLP-2) is a type of membrane factor, which is generally found highly expressed in various tumors. Collagen and calcium-binding EGF domain (CCBE1) belongs to lymphatic tube genesis factor. The regulatory role of SLP-2 gene on CCBE1 expression in RC tumor and adjacent lymphatic tube tissues, however, has not been studied. PATIENTS AND METHODS 52 RC patients were recruited, and tumor and adjacent lymphatic tube tissues were collected. Real-time PCR, western blotting and immunohistochemistry (IHC) staining were used to analyze SLP-2 and CCBE1 expressions. Human lymphatic endothelial cells (LECs) were cultured in vitro and were assigned to control, scramble, and SLP-2 siRNA group. MTT assay was used to detect cell proliferation, while caspase 3 activity was detected. RESULTS SLP-2 and CCBE1 levels were significantly elevated in tumor lymphatic tissues, compared to that in adjacent tissues. Statistically positive correlation between SLP-1 and CCBE2 was found (p<0.05). The downregulation of SLP-2 by siRNA inhibited cell proliferation, elevated caspase3 activity, and decreased CCBE1 expression (p<0.05 compared to control group). CONCLUSIONS SLP-2 is up-regulated in RC lymphatic tissues, and is positively correlated with the level of CCBE1, which provides the academic the basis for the development of medicine targeting SLP-2 in the anti-rectal carcinoma therapy.

Abstract
The death of several black bears at the black bear breeding base in Yunnan Pingbian Daweishan is a matter of concern. Multiple black bears exhibited decreased appetite or unusual waste, and some were soporific or suffered from vomiting and anhelation. In order to ascertain the cause of death, 16S rDNA gene sequencing and phylogenetic analysis was performed on bacteria isolated from tissue samples obtained from dead bears. The biochemical characteristics of the isolated bacteria were subsequently analyzed using different biochemical test systems. The bacteria can decompose glucose, but it cannot produce gas. The fermentation study of sucrose, lactose, trehalose, glycerol and mannitol yielded positive results; while it was unable to decompose urea or ODC (ornithine decarboxylase). Basic Local Alignment Search Tool (BLAST) analysis of a ~1500-bp DNA product amplified from the 16S rDNA of the bacterial isolate revealed that Enterococcus faecium from black bears is highly similar to other E. faecium isolates in the National Center for Biotechnology Information (NCBI) database, and the highest sequence similarity (99%) was with the reference strain. In addition, mice infected with the E. faecium isolate succumbed to severe damage to the lungs, liver, spleen, myocardium, and kidney tissues. In summary, the isolated E. faecium from dead black bears induced pathological changes in mice.

Abstract
Dielectric materials typically demonstrate poor thermal conductivity, which limits their application in emerging technologies in integrated circuits, computer chips, light-emitting diode lamps, and other electronic packaging areas. Using liquid metal microdroplets as inclusions to develop thermal interface materials has been shown to effectively improve thermal pathways, but this type of material may become electroconductive with the application of a concentrated compressive stress. In this study, an isotropic nano-liquid metal thermally-conductive and electrically-insulating material (nLM-THEM) is developed by combining a modified polymer and well-dispersed nanoparticles, achieving an ∼50× increase in thermal conductivity over the base polymer. In addition, the thermal conductivity of nLM-THEMs exhibits no significant change with varying humidity and a stable anti-corrosion effect even in direct contact with aluminum. More importantly, nLM-THEMs demonstrate a stable electrical insulating property upon compressive stress, while conventional micro-LM-THEMs exude liquid metal. This exceptional combination of thermal and electrical insulation properties is enabled by the interconnection of uniform and spherical liquid metal nanoparticles to create more thermally-conductive pathways, and surfactant modified nanoparticles ensure excellent electric insulation. Moreover, this material can achieve passive heat exchange through rapid heat dissipation, which demonstrates its great application potential in the electronic packaging area. Compared to liquid metal (LM) microdroplets based thermally conductive materials (micro-LM-THEMs), nano LM-THEMs (nLM-THEMs) presents a more stable electric insulating property even upon stress, achieving ~50-fold thermal conductivity over base polymer.![]()

Abstract
Macdunnoughia crassisigna Warren (Lepidoptera: Noctuidae) is a highly destructive herbivore that poses a serious risk to cotton, maize, soybean, and cruciferous vegetables in East Asia. Examining the effects of various biotic and abiotic factors on the flight performance of M. crassisigna is crucial for a better understanding of its trans-regional migration. In this study, the flight activity of M. crassisignai moths of different ages, under different temperatures and relative humidity (RH) levels, was evaluated by tethering individuals to computerized flight mills for a 24-h trial period. The results showed that M. crassisignai had the capacity for sustained flight and the flight ability was strongest in 3-day-old individuals, and then their flight performance decreased significantly in older moths. For both sexes, temperature had a significant effect on their flight performance, and the flight activity was relatively higher at 24-28°C than other temperatures. There was a significant effect of RH on all flight parameters of the tested moths, and the flight activity was relatively higher at RH of 60-75% than other RH levels. For 3-day-old moths under the optimum conditions (24°C and 75% RH) throughout the 24 h scotophase, their mean flight distance reached 66 km, and the mean flight duration reached 13.5 h, suggesting M. crassisigna possess strong potential to undertake long-distance migration. These findings will be helpful for developing sound forecasting systems of this pest species.
