Abstract
Formation of minerals such as calcium carbonate often causes energy consumption and even safety risk increase due to the hindrance on heat/mass transfer. However, the current antiscalants are not efficient enough because of the poor understanding of the scale inhibition mechanisms. Here, we report an ultrahigh-performance antiscalant, graphene oxide (GO), which exhibits an outstanding nucleation inhibition effect far better than the current state-of-the-art antiscalants even on a subppm dosage. Our experiments reveal that the superior nucleation inhibition effect of GO is attributed to its limiting effect on the nucleation kinetics of ions and its ability to increase the nucleation barrier of calcium carbonate by altering the normal pathway of calcium carbonate polymorph formation. Further analysis indicates that the ion-limiting effect and the polymorph control ability of GO may stem from its oxygen functional group-rich surface chemistry and two-dimensional (2D) planar features, which endow GO with a Ca2+ binding ability and additional steric hindrance for CO32- diffusion, respectively.

Abstract
In order to develop novel high damping materials with excellent pseudoelasticity (PE) properties to meet the application requirements in aerospace, medical, military and other fields, porous Ni50.8Ti49.2 shape memory alloy (SMA) was prepared by the powder metallurgy method. Different contents of Nb element were added to regulate the microstructures. It was found that after adding the Nb element, the number of precipitates significantly decreased, and the Nb element was mainly distributed in the Ni-Ti matrix in the form of β-Nb blocks surrounded by Nb-rich layers. Property tests showed that with the increase in Nb content, the damping and PE increased first and then decreased. When the Nb content reached 9.0 at.%, the highest damping and the best PE could be achieved. Compared with the porous Ni-Ti SMA without Nb addition, the damping and PE increased by 60% and 35%, respectively. Correlated mechanisms were discussed.

Abstract
Objective: To examine the application value of 3D Slicer software assisted domestic frameless stereotactic robot in biopsy of intracranial lesions. Methods: A retrospective analysis was performed on 80 patients who admitted consecutively and underwent intracerebral lesions biopsy with the domestic frameless stereotactic robot at Department of Neurosurgery, Aerospace Central Hospital from January 2019 to December 2021. There were 36 males and 44 females, with a mean age of (38.5±18.0) years (range: 6 to 71 years). Before surgery only enhanced T1-weighted three-dimensional magnetization prepared gradient echo sequences and diffusion tensor imaging scans were performed. Self-reconstruction of intracranial lesions, cerebral cortex and blood vessels was carried out using 3D Slicer software system after the DICOM format imaging data of 80 patients were collected. These imaging data were merged to the workstation of the domestic frameless stereotactic robot for preoperative surgical planning and the surgical puncture path was designed to avoid blood vessels in the brain functional area, cerebral cortex and sulcus. Results: All frameless stereotactic biopsy were successfully performed. Postoperative pathological diagnosis included 50 cases of diffuse astrocytic and oligodendroglioma, 15 cases of lymphoma, 5 cases of metastatic tumors, 5 cases of inflammatory demyelinating disease, 2 cases of inflammatory granuloma, 1 case of hemangioma, 1 case of acute lymphoblastic leukemia intracranial invasion and 1 case of seminoma. The positive diagnosis rate was 100% (80/80). Postoperative imaging confirmed that the puncture path and target were accurately implemented according to the preoperative planning, and the target error was (1.32±0.44) mm (range: 0.55 to 1.99 mm). One case of puncture-related bleeding occurred at the target after surgery and improved after treatment. Conclusion: The three-dimensional multimodal images reconstructed by the 3D Slicer software before operation could help the surgeons make the preoperative planning and reduce the risk of stereotactic brain biopsy.

Abstract
OBJECTIVE To explore the effect of dihydromyricetin on the expression of miR-98-5p and its mechanism in the development of Herceptin resistance in SKBR3 cells. METHODS The expression of IGF2 and miR-98-5p and their interaction relationship were analyzed by bioinformatics analysis through TargetScan online databases. SKBR3 cells and drug-resistant SKBR3-R cells were cultured in cell experiments. Xenograft tumor mice were constructed by SKBR3 and SKBR3-R cells. Proteins were detected by western blotting and immunohistochemistry. Transfected cells were constructed by shRNA lentivirus vectors. RT-QPCR was used to detect RNA. Cell proliferation was detected by MTS method. Cell jnvasion was detected by Transwell assay. Luciferase reporting assays were used to verify RNA interactions. IGF-1R/HER2 heterodimer was determined by immunocoprecipitation. RESULTS The expression of IGF2, p-IGF1R, p-Akt and p-S6K in SKBR3-R cells were significantly higher than those in SKBR3 cells, while the expression of PTEN protein was lower in SKBR3-R cells (P < 0.05). IGF1R/HER2 heterodimer in SKBR3-R cells was significantly increased (P < 0.01).The expression of IGF2 and invasion ability were significantly reduced while transfected with miR-98-5p in SKBR3-R cells (P < 0.05), but the IGF2 mRNA were no difference in both cells (P > 0.05). The expression of miR-98-5p was up-regulated and IGF2 was decreased in drug-resistant xenograft tumor mice after feeding with dihydromyricetin, and the tumor became more sensitivity to Herceptin (P < 0.05). CONCLUSION Dihydromyricetin could induce the expression of miR-98-5p, which binds to IGF2 mRNA to reduce IGF2 expression, inhibit the IGF-1R/HER2 formation, thereby reversing cell resistance to Herceptin in SKBR3-R cells.

Abstract
Black phosphorus (BP) nanosheets have been receiving attention for gas sensing showing superior sensitivity and selectivity among various two-dimensional materials. However, the instability of BP nanosheets due to chemical degradation, especially in humid environments, has severely limited their potential applications. Here, we propose to control the chemical stability of BP nanosheets through modifying their end groups via silanization treatment. Compared with other chemical passivation methods, the end group modification strategy proposed here can be well-controlled and results in little variation in the electronic structure of the puckered phosphorus plane. The results show that modification with fluoroalkylsilane leads the hydrophilic BP to become hydrophobic and exhibits extended chemical stability in oxidizing, humid environments. The sensitivity of fluoroalkylsilane-modified BP (F-BP) to NO2 improved by 3.9-fold in comparison with that of pristine BP nanosheets. More importantly, the NO2 sensing response could remain stable under changing relative humidity ranging from 5% to 95%. Such excellent sensing performance is ascribed to the strong interaction between NO2 and BP decorated with fluoroalkylsilane, as confirmed by density functional theory calculations. This work offers an effective means for preventing degradation of BP in ambient environments and provides a promising solution to solve the issue regarding humidity dependence in gas sensors.

Abstract
OBJECTIVE To explore the preoperative radiomics features (RFs) and construct a nomogram for predicting postoperative recurrence of stage Ⅰ-Ⅲ clear cell renal carcinoma (ccRCC). METHODS The clinicopathological data and preoperative enhanced CT images collected from 256 patients with ccRCC were used as the training dataset (175 patients) and test dataset (81 patients). The enhanced CT images of the tumor were segmented using ITK-SNAP software, and the RFs were extracted using the PyRadiomics computing platform. In the training dataset, the RFs were screened based on Lasso-CV algorithm, and the Rad_score was calculated. The Clinic factors were screened by univariate and multivariate logistic regression analysis of the clinical and pathological factors and CT characteristics. The Rad_score, Clinic、Rad_score + Clinic nomograms were constructed and verified using the test dataset. The performance, discrimination power and calibration of the nomograms were compared, and their clinical value was evaluated using decision curve analysis. RESULTS Six RFs were retained to calculate the Rad_score. The Clinic factors included Rad_score, KPS score, platelet, calcification and TNM clinical stage. In terms of discrimination, the Rad_score + Clinic nomogram showed better performance (AUC=0.84 for training set; AUC=0.85 for test set) than the Rad_score nomogram (AUC=0.78 for training set, P=0.029; AUC=0.77 for Test set, P=0.025) and Clinic nomogram (AUC=0.77 for training set, P=0.014; AUC=0.77 for test set, P=0.011). In terms of calibration, the P value for goodness of fit test of the Rad_score+Clinic nomogram was 0.065 for the training set and 0.628 for the test set. Decision curve analysis showed a greater clinical value of the Rad_score+Clinic nomogram with Rad_score than the Clinic nomogram without Rad_score. CONCLUSION The nomogram based on preoperative CT RFs has a high value for predicting postoperative recurrence of stage Ⅰ-Ⅲ ccRCC to facilitate individualized treatment of RCC.

Abstract
Tight stacking between two-dimensional (2D) sheet-like materials, such as graphene, in the solid state is a major challenge hindering their applications, especially in the gas sensing field. Here, we report on a TiO2 nanoparticle-spaced reduced graphene oxide (RGO) assembly for the design of highly sensitive gas sensors. The TiO2 nanospacers are derived from a 2D MXene that is intercalated between RGO sheets. The produced TiO2-spaced RGO assembly exhibits a uniform nanoparticle distribution and highly wrinkled RGO sheets that interconnect in micrometer-scale pores. The space limitation between adjacent RGO sheets can restrict the particle growth and lead to the formation of TiO2 nanoparticles with uniform diameters of ca. 6.2 nm. The sensitivity of the TiO2-spaced RGO sensor to NO2 improved by over 400% in comparison with pure RGO due to the more available surface area and active adsorption sites. Furthermore, fast response and recovery, excellent selectivity and flexibility, and reliable workability in a humid environment (with the relative humidity ranging from 5 to 95%) were also simultaneously achieved, demonstrating great potential for next-generation wearable sensors.

Abstract
OBJECTIVE This study was designed to investigate the expression of syndecan-1 (Sdc-1), protein kinase C (PKC) and vascular endothelial growth factor (VEGF) in rats with acute kidney injury, as well as the association between Sdc-1 and indicators [such as serum creatinine (Scr) and blood urea nitrogen (BUN)] related to renal function. MATERIALS AND METHODS A total of 120 clean grade 2-week-old SD rats were selected and randomized into experimental group and control group (n=60). At 12 h (T1), 24 h (T2), 36 h (T3), 48 h (T4) after the model was established, 3 mL blood from abdominal aorta was taken, and Sdc-1, PKC, VEGF, serum creatinine (Scr), urea nitrogen (BUN) and other indicators were detected by Enzyme-Linked Immunosorbent Assay (ELISA). RESULTS The expression levels of Sdc-1, PKC and VEGF in the experimental group were increasing from T1 to T4, with statistically significant difference between every two time points (p<0.05); the expression levels of Scr and BUN in the experimental group was increasing from T1 to T4, with statistically significant difference between every two time points (p<0.05). The level of Sdc-1 in the serum of rats in the experimental group was positively correlated with Scr (r=0.668, p<0.001), negatively correlated with BUN (r=0.722, p<0.001), and positively correlated with BUN (r=0.722, p<0.001); PKC level was positively correlated with Scr (r=0.589, p<0.001), BUN (r=0.788, p<0.001), and VEGF level was positively correlated with Scr (r=0.666, p<0.001), BUN (r=0.784, p<0.001). CONCLUSIONS As the concentration of syndecan-1 increases gradually, renal dysfunction aggravates accordingly, so syndecan-1 can be used as a marker of acute kidney injury and can be used to judge the degree of kidney injury at an early stage.

Abstract
Currently, electromagnetic radiation and interference have a significant effect on the operation of electronic devices and human health systems. Thus, developing excellent microwave absorbers have a huge significance in the material research field. Herein, a kind of ultrafine zinc oxide (ZnO) nanoparticles (NPs) supported on three-dimensional (3D) ordered mesoporous carbon spheres (ZnO/OMCS) is prepared from silica inverse opal by using phenolic resol precursor as carbon source. The prepared lightweight ZnO/OMCS nanocomposites exhibit 3D ordered carbon sphere array and highly dispersed ultrafine ZnO NPs on the mesoporous cell walls of carbon spheres. ZnO/OMCS-30 shows microwave absorbing ability with a strong absorption (- 39.3 dB at 10.4 GHz with a small thickness of 2 mm) and a broad effective absorption bandwidth (9.1 GHz). The outstanding microwave absorbing ability benefits to the well-dispersed ultrafine ZnO NPs and the 3D ordered mesoporous carbon spheres structure. This work opened up a unique way for developing lightweight and high-efficient carbon-based microwave absorbing materials.

Abstract
Oral squamous cell carcinoma (OSCC) accounts for approximately 90% of malignant epithelial tumors of the oral and maxillofacial region. OSCC has high rate of metastasis and poor prognosis. Tobacco and/or alcohol consumption and human papillomavirus infection are relatively exact susceptibility factors for OSCC, but the specific process of oral mucosal carcinogenesis and progression is very complicated. microRNA-302b (miR-302b) could regulate various characteristics of many tumor cells, such as proliferation and apoptosis, but its role and mechanism in OSCC have not been reported. This research aims to study the effect of miR-302b on the invasion and migration ability of OSCC and the mechanism by which it functions as well as to identify new prognostic indicators and therapeutic targets for OSCC patients. Functional studies showed that the miR-302b level was negatively correlated with the invasion and migration ability of OSCC. The studies also showed that the overexpression of miR-302b could attenuate the invasion and migration ability of OSCC cells and reduce lymphangiogenesis and the lung metastasis rate of OSCC cells in a mouse model. Mechanistic studies were performed by quantitative polymerase chain reactions, luciferase assays, and RNA pull-down experiments. The results verified that frizzled class receptor 6 (FZD6) is a target gene of miR-302b in OSCC that could promote cell invasion and migration. Clinical studies demonstrate that the protein expression level of FZD6 was higher in OSCC and metastatic lymph nodes than in normal oral mucosa epithelium. Taken together, these data showed that miR-302b could inhibit the invasion and migration ability of OSCC cells by targeting and downregulating FZD6, thereby inhibiting OSCC metastasis. As a new target gene of miR-302b, FZD6 has the potential to become a prognostic and therapeutic target for OSCC patients.

Abstract
Nano heterostructures relying on their versatile construction and the breadth of combined functionality have shown great potential in energy storage fields. Herein, 2D sandwiched MoSe2 /TiO2- x /graphene nano heterostructures are designed by integrating structural and functional effects of each component, aiming to address the rate capability and cyclic stability of MoSe2 for sodium ion capacitors (SICs). These 2D nano heterostructures based on graphene platform can facilitate the interfacial electron transport, giving rise to fast reaction kinetics. Meanwhile, the 2D open structure induces a large extent of surface capacitive contribution, eventually leading to a high rate capability (415.2 mAh g-1 @ 5 A g-1 ). An ultrathin oxygen deficient TiO2- x layer sandwiched in these nano heterostructures provides a strong chemical-anchoring regarding the products generated during the sodiation/desodiation process, securing the entire cyclic stability. The associated sodiation/desodiation mechanism is revealed by operando and ex situ characterizations, which exhibits a strong solid electrolyte interphase (SEI) dependence. The simulations verify the dependent sodiation products and enhanced heterostructural chemical-anchoring. Assembled SICs based on these nano heterostructures anode exhibit high initial Coulombic efficiency, energy/power densities, and long cycle life, shedding new light on the design of nano heterostructure electrodes for high performance energy storage application.

Abstract
Abstract
Introduction/Objective
Russell bodies are nondegradable, condensed immunoglobulins accumulated in the overstimulated plasma cells, and the plasma cells filled with Russell bodies are called Mott cells. Russell body gastroenteritis is a rare entity that is mainly occurs in stomach and is associated with Helicobacter pylori infection.
However, Russell body duodenitis is very rarely seen, so far only about four cases have been reported. Here we report a case of Russell body duodenitis within concurrent large duodenal adenoma with high-grade dysplasia in a 66- year old female.
Methods
Formalin fixed, paraffin embedded tissue was examined stained with H&E and PAS-Alcian blue stain. Immunohistochemical stains (IHC) with appropriate controls were performed with the following antibodies: H. pylori, CD138, kappa and lambda light chains.
Results
A 66-year old female had symptoms of difficult swallowing and decreased food intake. Upper GI endoscopy was performed to reveal a 7 cm multilobulated mass at the junction of the duodenal bulb and second portion of the duodenum, which involved the ampullary orifice. A biopsy for the mass showed a duodenal adenoma with high grade dysplasia. Numerous Mott cells were diffusely distributed within the lamina propria that was characterized by bright eosinophilic cytoplasmic globules with eccentric nuclei. The Mott cells were confirmed by IHC stains with positive CD138, PAS-Alcian blue, and polytypic expression of kappa and lambda light chains. The Helicobacter pylori immunostain was negative.
Conclusion
Although the etiology is unknown, most of the Russell body gastroenteritis are seen in benign conditions. It is mainly found in stomach associated with Helicobacter pylori infection. To our knowledge, this is the first reported case of Russell body duodenitis with concurrent duodenal adenoma with high-grade dysplasia. Further studies should be conducted on Russell bodies associated with high-grade dysplasia or carcinoma in gastrointestinal tract.

Abstract
Objective: To establish the mice colorectal cancer (CRC) model induced by AOM/DSS with the intervention of high fat diet and probiotics, and to explore the potential mechanism of probiotics intervention in regulating intestinal flora disturbance and antitumor efficiency. Methods: Forty 8-week-old male C57BL/6J mice were randomly divided into 4 groups with 10 mice in each group: HFD group, HDF with probiotics intervention (HFD+P) group, normal diet (ND) group, normal diet with probiotics intervention (ND+P) group. The probiotic groups were administered with probiotics preparation by gavage. During the experiment, AOM/DSS was used to induce mouse colorectal cancer model. The mouse body weight was regularly recorded and the body status was evaluated weekly. High-throughput 16S rDNA sequencing was used to analyze the changes of fecal flora in bacterial structure before and after cancer induction. At the end of the experiment, intestinal tissues of mice were collected and the epididymis adipose mass (EAM) and tumor burden were recorded. The Alpha diversity index was used to analyze the abundance and diversity of the intestinal flora (higher chaol index means higher abundance of bacteria and greater Simpson index means lower diversity in flora structure). The Beta diversity index was used to analyze the significance of the difference in the distribution of intestinal flora among the four groups (When R>0, the difference in the distribution of bacteria among the groups is greater than the difference within the group). Results: After 15 weeks of experiment, the body weight of mice in HFD group, HFD+P group, ND group and ND+P group was (33.70±0.52) g, (28.70±0.32) g, (25.90±0.34) g and (25.60±0.40) g, whose difference was statistically significant (F=700.89, P<0.01). The body weight of HFD group was higher than that of ND group and HFD+P group while the body weight of HFD+P group was still higher than that of ND group, and the differences were statistically significant (all P<0.017). The average EAM of HFD group, HFD+P group, ND group and ND+P group was (1.36±0.15) g, (0.67±0.08) g, (0.58±0.10) g and (0.54±0.05) g, whose difference was statistically significant (F=114.03, P<0.01). Pairwise comparisons showed that EAM in HFD group was higher than that in ND group and HFD+P group respectively, with statistically significant difference (both P<0.01), while average EAM of HFD+P group was similar to ND group (P=0.09). Under the diet intervention, the Chao1 index of HFD group, HFD+P group, ND group and ND+P group was 217.62, 235.32, 301.51 and 305.71 respectively, and the Simpson index was 0.93, 0.89, 0.91 and 0.90. At the same time, the Anosim analysis of Beta diversity analysis showed that the difference in the flora distribution among four groups was greater than the difference with in each group with statistically significant difference (R=0.655, P=0.001). Species abundance analysis revealed that, compared with ND group, at phylum level, HFD group had a higher proportion of Bacteroides phylum and Firmicutes phylum in the intestinal flora and lower proportion of Verrucomicrobia; at genus level, the proportion of Bacteroides and Oscillibacter in HFD group was higher while the proportion of Akkermansia and Alloprevotella was lower. After the intervention of probiotics, the flora mentioned above was improved significantly except for Alloprevotella. The average number of tumor in HFD group, HFD+P group, ND group and ND+P group was 4.63±1.19, 2.33±0.52, 2.56±0.73 and 2.38±0.52 with statistically significant difference (F=14.92, P<0.01). Conclusion: Probiotics therapy can reduce obesity and flora imbalance caused by HFD and reduce the incidence of CRC by regulating intestinal flora disturbance.

Abstract
Performance degradation of lithium/sodium-ion capacitors (LICs/SICs) mainly originates from anode pulverization, particularly the alloying and conversion types, and has spurred research for alternatives with an insertion mechanism. Three-dimensional (3D) topotactic host materials remain much unexplored compared to two-dimensional (2D) ones (graphite, etc.). Herein, vanadium monophosphide (VP) is designed as a 3D topotactic host anode. Ex situ electrochemical characterizations reveal that there are no phase changes during (de)intercalation, which follows the topotactic intercalation mechanism. Computational simulations also confirm the metallic feature and topotactic structure of VP with a spacious interstitial position for the accommodation of guest species. To boost the electrochemical performance, carbon nano-onions (CNOs) are coupled with 3D VP. Superior specific capacity and rate capability of VP-CNOs vs lithium/sodium can be delivered due to the fast ion diffusion nature. An exceptional capacity retention of above 86% is maintained after 20 000 cycles, benefitting from the topotactic intercalation process. The optimized LICs/SICs exhibit high energy/power densities and an ultrastable lifespan of 20 000 cycles, which outperform most of the state-of-the-art LICs and SICs, demonstrating the potential of VP-CNOs as insertion anodes. This exploration would draw attention with regard to insertion anodes with 3D topotactic host topology and provide new insights into anode selection for LICs/SICs.

Abstract
Although various bio-inspired materials with outstanding mechanical, acoustic, and optic properties have been developed, bio-inspired materials for microwave absorption applications are rarely reported. Herein, under the inspiration of the opal structure, for the first time, a kind of Co@Co3O4/nitrogen-doped (N-doped) mesoporous carbon sphere (Co@Co3O4/NMCS) with a periodic three-dimensional structure toward microwave absorption application was designed and synthesized. The microwave absorption performance was optimized with respect to the content of Co@Co3O4 nanoparticles. Co@Co3O4/NMCS with ∼20 wt % Co@Co3O4 achieves a reflection loss of -53.8 dB at 5.7 GHz. The simulated radar cross section demonstrated that the Co@Co3O4/NMCS can efficiently suppress the strong electromagnetic scattering from a metal groove structure, which further reveals its excellent absorbing performance. These periodic porous structures of N-doped mesoporous carbon spheres combined with the magnetic Co@Co3O4 nanoparticles contribute to the excellent microwave-absorbing performance.

Abstract
Gas sensors with high sensitivity, fast response/recovery, good selectivity, and room-temperature operation are highly desirable for practical use. However, most of the existing gas sensing materials, either conventional metal oxide semiconductors or advanced inorganic two-dimensional (2D) polymers, can hardly satisfy the above requirements. Herein, we demonstrate an organic 2D polymer derived from a covalent triazine framework (CTF), which possesses nanoscale thickness, intrinsic and periodic pore structures, and abundant functional groups with excellent gas sensing performance. The as-prepared triazine-based 2D polymer (T-2DP) exhibits selective recognition to NO2 with an ultrahigh sensitivity of 452.6 ppm-1, which outperforms most other 2D nanomaterials and its CTF matrix. The sensing effect is superfast (35-47 s) and fully reversible operated at room temperature. The superior comprehensive gas sensing performance of T-2DP and the underlying mechanism was experimentally studied and further discussed by comparison with that of CTF and widely investigated inorganic 2D polymers including graphene and MXene. As a proof of concept, a flexible NO2 chemiresistor based on T-2DP was fabricated to demonstrate its potential for integration into wearable electronics. The scientific findings in this work may propose a new route for the design of high-performance gas sensing materials on the basis of organic 2D polymers in next-generation wearable electronic devices.

Abstract
OBJECTIVE The aim of the present study was to examine the expression of miR-205 in renal cell carcinoma (RCC) tissue and carcinoma cells; also, we aimed to determine the association of miR-205 expression with the clinicopathological features and prognosis of RCC, and to explore the mechanism of miR-205. PATIENTS AND METHODS Carcinoma tissue and adjacent normal tissue were collected from 60 patients with RCC, and the expression of miR-205 was determined by semi-quantitative PCR, followed by correlation analysis of miR-205 with clinicopathological features and prognosis. Subsequently, the human RCC line, ACHN, was transfected with miR-205, and the effect of miR-205 overexpression on the growth of RCC was examined by MTT assay. Moreover, the effect of miR-205 on the migration of colon cancer cells was studied by transwell assay. Additionally, immunohistochemistry and Western blot were used to investigate the epithelial-mesenchymal transition in renal cancer tissue. RESULTS The expression of miR-205 was downregulated in RCC tissue compared with adjacent non-cancerous tissue (p < 0.01). The expression of miR-205 was closely related to the infiltration and recurrence of tumors (p < 0.01), but was not correlated with a pathological grade or clinical stage (p > 0.05). We also found that overexpression of miR-205 in RCC significantly inhibited the growth of cancer cells (p < 0.01) and significantly reduced the migration ability (p < 0.01). The epithelial-mesenchymal transition occurs in RCC, and miR-205 might inhibit cell proliferation and migration by blocking the epithelial-mesenchymal transition. CONCLUSIONS The expression of miR-205 is low in RCC, and may play an important role throughout the progression of RCC. Further study of miR-205 may promote the development of a novel therapeutic approach for the treatment of RCC.

Abstract
Flexible and multifunctional strain sensors with superior properties including high sensitivity, low detection limits, and a wide sensing range are always in high demand for wearable electronics. However, it remains a big challenge to fully satisfy the aforementioned requirements. In particular, there is always a trade-off between high sensitivity and wide sensing range. Here, we developed a multifunctional strain sensor based on a network-structured MXene/polyurethane mat (network-M/P mat) and well balanced the relationship between the sensitivity and sensing range by rationally designing the morphology and microstructures of the sensing device. The network-structured polyurethane mat (network-P mat) was fabricated through a facile and scalable electrospinning technique. The highly conductive MXene sheets were decorated onto the network-P mat through hydrogen bonding or electrostatic interactions. The obtained highly flexible and stretchable network-M/P mat exhibited a superior comprehensive sensing performance that was characterized by high sensitivity (gauge factor up to 228), a low limit of detection (0.1%), a large and tunable sensing range (up to 150%), excellent stability (over 3200 cycles), and multiple functions (lateral strain, vertical pressure, bending and subtle vibration). Based on its superior performance, the network-M/P mat-based strain sensor can detect a full range of body actions and subtle physiological signals (e.g. respirations and pulse waves), demonstrating great potential for applications in artificial electronic skin and wearable health detectors.

Abstract
Highly sensitive mechanical sensing is vital for the emerging field of skin mimicry and wearable healthcare systems. To date, it remains a big challenge to fabricate mechanosensors with both high sensitivity and a wide sensing range. In nature, slit sensilla are crack-shaped sensory organs of arachnids, which are highly sensitive to tiny external mechanical stimuli. Here, inspired by the geometry of slit sensilla, a concept is developed that pretextures reduced graphene oxide (RGO) nanocoating into multiscale topographies with agminated crumples and interlaced cracks (crumpled & cracked RGO) through an efficient and scalable mechanically driven process. Both the sensitivity and the workable range can be facilely tuned by adjusting the crack density. The resulting mechanosensor exhibits a comprehensive superior performance including high sensitivity (a gauge factor of 205 to 3256), a wide and tunable sensing range (from 0-40 to 0-180%), long-term stability (over 5000 cycles), and multiple sensing functions. Based on its excellent performances, the mechanosensor can be used as a wearable electronic to in situ monitor subtle physiological signals and vigorous body actions. The rationally designed crumpled & cracked RGO provides a promising platform for artificial electronic skin and portable healthcare systems.

Abstract
Using an age-structured process-based simulation model for diamondback moth (DBM), we model the population dynamics of this major Brassica pest using the cropping practices and climate of Guangdong, China. The model simulates two interacting sub-populations (demes), each representing a short season crop. The simulated DBM abundance, and hence pest problems, depend on planting regime, crop hygiene and biological control. A continuous supply of hosts, a low proportion of crop harvested and long residue times between harvest and replanting each exacerbate pest levels. Biological control provided by a larval parasitoid can reduce pest problems, but not eliminate them when climate is suitable for DBM and under certain planting practices. The classic Integrated Pest Management (IPM) method of insecticide application, when pest threshold is reached, proved effective and halved the number of insecticide sprays when compared with the typical practice of weekly insecticide application.

Abstract
Highly sensitive, selective, and room-temperature-performing gas sensors have always been the pursuit in the sensing field for practical applications. However, the existing gas sensors can seldom satisfy the aforementioned requirements. Here, we integrate zero-dimensional Ag nanoparticles (AgNPs), one-dimensional polymer fibers, and two-dimensional aminoanthroquinone-functionalized reduced graphene oxide (AQRGO) sheets into a three-dimensional sensing scaffold (AgNP-3D-AQRGO) for high-performance NO2 sensing. The AQ moieties and AgNPs are decorated onto the RGO sheets through a wet chemical route. Electrospinning and self-assembly techniques are employed to assemble the polymer fibers and the functional RGO sheets into a three-dimensional scaffold. The resulting AgNP-3D-AQRGO-based gas sensor can perform at room temperature and exhibits excellent sensing performance for NO2, including an ultrahigh sensitivity (10.3 ppm-1), an ultralow limit of detection (0.6 ppb), and an extremely remarkable selectivity to solely NO2 molecules. Furthermore, the sensor is also highly flexible, demonstrating great potential for portable and real-time monitoring of toxic gas in personal mobile electronics.

Abstract
In this work, a unique three-dimensional (3D) structured carbon-based composite was synthesized. In the composite, multiwalled carbon nanotubes (MWCNT) form a lattice matrix in which porous spherical reduced graphene oxide (RGO) completes the 3D structure. When used in Li-S batteries, the 3D porous lattice matrix not only accommodates a high content of sulfur, but also induces a confinement effect towards polysulfide, and thereby reduces the "shuttle effect". The as-prepared S-3D-RGO@MWCNT composite delivers an initial specific capacity of 1102 mAh·g-1. After 200 charging/discharge cycles, a capacity of 805 mAh·g-1 and a coulombic efficiency of 98% were maintained, implying the shuttle effect was greatly suppressed by the composite matrix. In addition, the S-3D-RGO@MWCNT composite also exhibits an excellent rate capability.

Abstract
Hundreds of farmed Siamese crocodiles (Crocodylus siamensis) died during July 2016 at a farm in Wenchang, Hainan, China. In two necropsied crocodiles, we observed symptoms of dermatorrhagia, hepatomegaly and hepatic congestion. Pulmonitis was diagnosed by pulmonary congestion and pulmonary fibrinous exudate. Septicaemia was diagnosed by isolation of three Aeromonas species from blood and visceral tissues; A. dhakensis, A. hydrophila and A. jandaei were identified by biochemical and molecular tests. We used a zebrafish model to determine the half-maximal lethal dose (LD50 ), and A. dhakensis was found to be the most virulent species, with an LD50 of 8·91 × 105 CFU per ml. The results of a drug sensitivity test indicated that these species were sensitive to 11 antibiotics. This is the first report of A. dhakensis, A. hydrophila and A. jandaei being isolated from a mixed infection in Siamese crocodiles. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, we isolated three species of Aeromonas (A. dhakensis, A. hydrophila and A. jandae) from farmed Siamese crocodiles with fatal fibrinous pneumonia and septicaemia. This is the first description of a mixed infection with three Aeromonas species among captive crocodilians.

Abstract
Objective: To summarize the clinical manifestations and gene variations of combined immunodeficiency caused by ORAI1 variation with a case report and literature review. Methods: The clinical data of the patient who was diagnosed with ORAI1 variation caused combined immunodeficiency in the Department of Pediatrics in Xiangya Hospital of Central South University in February 2018 were extracted and analyzed. The literature till August 2018 was searched with key words of 'ORAI1', and 'immunodeficiency' in both English and Chinese in the database of China national knowledge infrast ructure (CNKI), Wanfang and Pubmed. Results: The patient was a 15 months old girl with acute onset of bilateral ptosis after upper respiratory tract infection, which was rapidly progressed to systemic myasthenia and accompanied with recurrent respiratory tract infection during the treatment. The patient poorly to responded immunomodulatory therapy and anti-infection therapy. Laboratory tests demonstrated decreased complement C3 and NK cell (CD3(-)CD56(+)), increased anti-thyroglobulin, thyroid peroxidase antibody and B lymphocyte (CD3(-)CD19(+)), and slightly increased anti-acetylcholine receptor antibody. Genetic analysis showed the homozygous variation of ORAI1 gene exon l c.12 G>T (p.E4D), with heterozygostty of both parents. There were only 4 papers reporting this disease in the literature review. A total of 7 patients with ORAI1 gene variation were reported, including 3 homozygous variations, 2 heterozygous variations and 2 complex heterozygous variations. The clinical manifestations included early onset recurrent infection, congenital hypotonia, elevated serum IgA and IgM, decreased NK cells, and family history of hereditary diseases. Four of the 7 reported cases died of pulmonary infection and sepsis, and the other 3 survived with low muscular tone and poor self-care ability. Conclusions: The most common clinical manifestations of ORAI1 variation caused combined immunodeficiency are recurrent infection and congenital hypotonia. Myasthenia induced recurrent respiratory tract infection is an important factor of poor prognosis in severe patients. There is a lack of effective treatment for this disease, and the prognosis is poor.

Abstract
Objective: To report a family diagnosed with Allan-Herndon-Dudley syndrome (AHDS) due to SLC16A2 gene mutation and to summarize the phenotypes, genotypes, diagnosis, treatment, and prognosis. Methods: The clinical features of a family of AHDS diagnosed in Xiangya Hospital of Central South University in November 2017 were analyzed. Related literature was searched at Online Mendelian Inheritance in Man (OMIM), PubMed, CNKI and Wanfang database (from the establishment of databases to June 2018) by using "Allan-Herndon-Dudley syndrome" , and "AHDS" as keywords and the case reports from April 2013 to June 2018 were reviewed. Results: The proband was a boy aged 8 months who presented with global developmental retardation, inability to hold up the head, disability to sit independently or grab, no language development, elongated face, big ears, esotropia, scoliosis, hypotonia in the trunk, hypertonia in extremities, and hyperreflexia. Brain magnetic resonance imaging (MRI) showed widening of the extracerebral space and delayed myelination. Thyroid function tests revealed increased FT3, decreased FT4 and normal TSH. Whole exome sequencing (WES) revealed the SLC16A2 gene c.431-1 (IVS1) G>C hemizygous mutation. The infant's mother and grandmother are carriers, but whose father had no related mutation. One uncle from maternal side had severe psychomotor retardation as well as dystonia and died at one year of age with unknown etiology. A total of 97 articles were retrieved in which 19 case reports were reviewed. Forty-two cases (22 from 8 families and 20 sporadic) were reported. Among these 42 cases (all males), all of them presented with moderate to severe cognitive dysfunction, 15 with seizures; 36 were bedridden, only 4 could walk; 31 had no language development, 2 could speak sentences, 4 could speak few words, 1 had babbling sounds. Furthermore,16 had microcephaly, 18 had facial dysmorphism, 6 had esotropia, 2 had hearing loss,14 had scoliosis, 11 had joint contracture, 30 had low body weight/muscle wasting, 37 had hypotonia in trunk or extremities, 32 had progressive spastic paraplegia or hypertonia. In terms of thyroid function, 33 had abnormal results, within whom 30 had increased T3, 25 had decreased T4 and 3 had increased TSH. Brain MRI showed delayed myelination in 22 cases, within which one normalized with development. Genetic tests showed that 31 had missense mutation (14 sporadic), 5 had deletion mutation (3 sporadic, and 1 due to frameshift mutation), 5 had insertion mutation (2 sporadic), and 1 had repeated mutation. The prognosis was poor as patients often died of recurrent respiratory tract infection. Conclusions: The main clinical manifestations of AHDS are severe global developmental retardation, hypotonia, spastic paraplegia, abnormal serum levels of thyroid hormone and delayed brain myelination. SLC16A2 c. 431-1 (IVS1) G > C mutation is accountable for this disease.

Abstract
To enhance the electrochemical performance of the lithium/sulfur batteries, a novel interlayer was prepared by coating the slurry of PPy/ZnO composite onto the surface of a separator. Owing to a three-dimensional hierarchical network structure, PPy/ZnO composite serves as a polysulfide diffusion absorbent that can intercept the migrating soluble polysulfides to enhance the electrochemical performance of the Li/S batteries. The specific capacity of the cell with PPy/ZnO interlayer remained at 579 mAh g-1 after 100 cycles at 0.2 C. This interlayer can provide novel avenues for the commercial applications of Li/S batteries.

Abstract
The development of skinlike strain sensors that are integrated with multiple sensing functions has attracted tremendous attention in recent years. To mimic human skin, strain sensors should have the abilities to detect various deformations such as pressing, stretching, bending, and even subtle vibrations. Here, we developed a facile, cost-effective, and scalable method for fabrication of high-performance strain sensors based on a graphene-coated springlike mesh network. This composite-based sensor exhibits an incorporation of low detection limit (LOD) for minute deformation (LOD of 1.38 Pa for pressure, 0.1% for tensile strain, and 10 μm for vibration), multiple sensing functions, long-term stability, and wide maximal sensing range (up to 80 kPa for pressure and 110% for tensile strain). On the basis of its superior performance, it can be applied for in situ monitoring of human motions ranging from subtle physiological signals (e.g., pulse, respiration, and phonation) to substantial movements (e.g., finger bending).

Abstract
The structural, electronic and magnetic properties of Cr, Mn, Fe, Co and Ni-doped bilayer WSe2 are predicted by using first principles calculations. The doped transition-metal (TM) atoms show a covalent-binding with the nearest Se atoms. The calculated electronic structures reveal that the TM Cr, Mn, Fe and Co-doped bilayer WSe2 exhibits a half-metallic character with a 100% spin polarization at the Fermi level, and the reason is ascribed to the strong hybridization peak between the transition metals and the parent W and Se atoms. The Ni-doped bilayer WSe2 is still a semiconductor with nonmagnetism. The Fe-doped system has a robust stability of half-metallicity because there are three connected states peak spanning the Fermi level. The doping of Cr, Mn, Fe and Co atoms leads to a prominent total magnetism (0.93-3.65 [Formula: see text] moment per unit cell), and an induced ∼0.3 [Formula: see text] moment in parent W atoms is found in addition to the main contribution of TM atomic magnetism (0.71-3.33 [Formula: see text] moment per atom). The predicted Cr, Mn, Fe and Co-doped bilayer WSe2 should be the candidate materials for spintronic devices due to their magnetic and half-metallic nature.

Abstract
An efficient, industry-accepted spray drying method was used to synthesize micro-spherical sulfur/graphene oxide (S/GO) composites as cathode materials within lithium sulfur batteries. The as-designed wrapping of the sulfur-nanoparticles, with wrinkled GO composites, was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The unique morphological design of this material enabled superior discharge capacity and cycling performance, demonstrating a high initial discharge capacity of 1400 mAh g−1 at 0.1 C. The discharge capacity remained at 828 mAh g−1 after 150 cycles. The superior electrochemical performance indicates that the S/GO composite improves electrical conductivity and alleviates the shuttle effect. This study represents the first time such a facile spray drying method has been adopted for lithium sulfur batteries and used in the fabrication of S/GO composites.

Abstract
An experiment was carried out to evaluate the short-term effect of supplementing a nucleotide-rich yeast extract (NRYE) on growth performance, gut structure, immunity and microflora of piglets raised under sanitary and unsanitary conditions. A total of 84, 21-day old piglets were used in this study; 42 piglets were raised in a room designated as the clean room that was washed once per week, whereas the other 42 piglets were raised in a room designated as the unclean room in which 7 kg of manure from the sow herd was spread on each pen floor on day 1 and 7 and the room was not washed throughout the experiment. The pigs were fed a corn-soybean meal-based diet without or with 0.1% NRYE. Each treatment had 7 replicate pens in each room, and each pen housed 3 pigs. Feed disappearance and BW were recorded on day 1 and 14. On day 14, one pig per pen was euthanized to collect ileum, mesenteric lymph nodes and spleen tissues, and cecum and colon digesta. Overall, NRYE supplementation did not affect growth performance in both clean and unclean conditions, improved kidney weight in both clean (P=0.0002) and unclean room (P<0.0001) and tended to improve the villus height/crypt depth ratio in the clean room (P=0.073). Supplementing NRYE was associated with upregulation of Ileal programmed cell death gene-1 (P=0.0003), interleukin (IL)-1β (P<0.0001), IL-6 (P=0.0003), IL-10 (P<0.0001) and tumor necrosis factor-α (TNF-α) (P<0.0001) in pigs raised in the unclean room. Supplementing the NRYE in pigs raised in the clean room suppressed growth of cecal Enterobacteriacea (P<0.0001) members and colonic Enterococcus spp. (P<0.019), improved proliferation of cecal Lactobacillus spp. (P<0.002) and colonic Clostridium cluster IV (P<0.011) and XVIa members (P<0.0002). Supplementing the NRYE in the unclean room improved proliferation of cecal Clostridium cluster IV (P<0.026) and suppressed proliferation of colonic Enterococcus spp. (P<0.037). In conclusion, supplementing the NRYE to piglets under unsanitary conditions improved ileal immune response by upregulating inflammatory cytokines, and positively modulated proliferation of beneficial gut bacteria and suppression of harmful ones in both clean and unclean rooms.

Abstract
Carbon-coated silica nanoparticles anchored on multi-walled carbon nanotubes (SiO2@C/MWNT composite) were synthesized via a simple and facile sol-gel method followed by heat treatment. Scanning and transmission electron microscopy (SEM and TEM) studies confirmed densely anchoring the carbon-coated SiO2 nanoparticles onto a flexible MWNT conductive network, which facilitated fast electron and lithium-ion transport and improved structural stability of the composite. As prepared, ternary composite anode showed superior cyclability and rate capability compared to a carbon-coated silica counterpart without MWNT (SiO2@C). The SiO2@C/MWNT composite exhibited a high reversible discharge capacity of 744 mAh g-1 at the second discharge cycle conducted at a current density of 100 mA g-1 as well as an excellent rate capability, delivering a capacity of 475 mAh g-1 even at 1000 mA g-1. This enhanced electrochemical performance of SiO2@C/MWNT ternary composite anode was associated with its unique core-shell and networking structure and a strong mutual synergistic effect among the individual components.

Abstract
The aqueous sodium-ion battery (ASIB) is one of the promising new energy storage systems owing to the abundant resources of sodium as well as efficiency and safety of electrolyte. Herein, we report an ASIB system with Na4Mn9O18/carbon nanotube (NMO/CNT) as cathode, metal Zn as anode and a novel Na+/Zn2+ mixed ion as electrolyte. The NMO/CNT with microspherical structure is prepared by a simple spray-drying method. The prepared battery delivers a high reversible specific capacity and stable cyclability. Furthermore, the battery displays a stable reversible discharge capacity of 53.2 mAh g-1 even at a high current rate of 4 C after 150 cycles. Our results confirm that the NMO/CNT composite is a promising electrode cathode material for ASIBs.

Abstract
ZnO/nitrogen-doped carbon nanotube (ZnO/NCNT) composite, prepared though a simple one-step sol-gel synthetic technique, has been explored for the first time as an anode material. The as-prepared ZnO/NCNT nanocomposite preserves a good dispersity and homogeneity of the ZnO nanoparticles (~6 nm) which deposited on the surface of NCNT. Transmission electron microscopy (TEM) reveals the formation of ZnO nanoparticles with an average size of 6 nm homogeneously deposited on the surface of NCNT. ZnO/NCNT composite, when evaluated as an anode for lithium-ion batteries (LIBs), exhibits remarkably enhanced cycling ability and rate capability compared with the ZnO/CNT counterpart. A relatively large reversible capacity of 1013 mAh·g−1 is manifested at the second cycle and a capacity of 664 mAh·g−1 is retained after 100 cycles. Furthermore, the ZnO/NCNT system displays a reversible capacity of 308 mAh·g−1 even at a high current density of 1600 mA·g−1. These electrochemical performance enhancements are ascribed to the reinforced accumulative effects of the well-dispersed ZnO nanoparticles and doping nitrogen atoms, which can not only suppress the volumetric expansion of ZnO nanoparticles during the cycling performance but also provide a highly conductive NCNT network for ZnO anode.

Abstract
An aqueous sodium ion battery (ASIB) with metal Zn as anode and Na4Mn9O18-reduced graphene oxide (Na4Mn9O18-RGO) as cathode has been developed. In this work, spherical Na4Mn9O18-RGO composite particles were prepared via spray drying. The aqueous battery exhibits stable cyclability and high specific capacities. Typically, a high initial discharge capacity of 61.7 mAh·g−1 is attained at a high current rate of 4 C, and a stabilizing reversible capacity of 58.9 mAh·g−1 was obtained after 150 cycles. The network interlaced by RGO sheets provided fast electron conduction paths and structural stability to accommodate the mechanical stresses induced by sodium insertion and extraction, so the Na4Mn9O18-RGO electrode displayed superior electrochemical performance in the ASIB.

Abstract
OBJECTIVE miR-329-3p has been reported to serve as a tumor suppressor in the progression of cervical cancer (CC). The aim of this study was to investigate the clinical significance of miR-329-3p in human CC. PATIENTS AND METHODS Quantitative RT-PCR (qRT-PCR) was used to detect miR-329-3p expression in CC tissue samples and matched normal cervical tissues. The x2 test was used to analyze the association between miR-329-3p expression and clinical features of CC patients. Moreover, we evaluated the prognostic value of miR-329-3p by Kaplan-Meier survival curve and Cox regression model. RESULTS We found that the mean expression level of miR-329-3p in CC tissues was significantly lower than the mean level in the adjacent normal tissues samples (p < 0.01). MiR-329-3p level was significantly associated with lymph node metastasis (p = 0.013), FIGO stage (p = 0.024) and distant metastasis (p = 0.001). Furthermore, a significant difference was found, that CC patients with low miR-329-3p expression level had distinctly shorter overall survival than patients with high miR-329-3p expression level (p = 0.001). Finally, multivariate analyses indicated that miR-329-3p represented an independent predictor for overall survival of CC (p = 0.04). CONCLUSIONS These results indicated, for the first time, that down-regulation of miR-329-3p was associated with poor prognosis in CC patients. MiR-329-3p can be used as an independent factor to predict survival of patients with CC.

Abstract
Objective: To analyze the clinical and gene mutation characteristics of dynamin-1 (DNM1)-related infantile spasms. Method: Clinical, laboratory and genetic data of one case of DNM1-related infantile spasms diagnosed by Xiangya Hospital in September 2015 were analyzed.Through taking "Dynamin-1" "DNM1" as key words to search at CNKI, Wanfang, PubMed and OMIM to date (April 2016), the clinical characteristics of 9 reported cases of DNM1-related epileptic encephalopathy in international literature with our case were reviewed. Result: The boy is the second child of healthy and nonconsanguineous parents.At 7 months, he started to have seizures with head dropping, and he was brought for the first time to our hospital at the age of 17 months.The patient presented with severe psychomotor retardation, epilepsy, muscular hypotonia, and electroencephalography showed hypsarhythmia.He received 28 days of adrenocorticotropic hormone (ACTH) therapy.After that, his seizures were improved with valproic acid and levetiracetam, and disappeared between 3 years and 5 months to 5 years and 5 months of age on treatment with valproic acid only.Exome-sequencing study (trios) identified novel heterozygous mutation c. 443A>G (p.Glu148Arg) in DNM1. Up to now, 9 cases of epileptic encephalopathy (infantile spasms or Lennox-Gastaut syndrome) associated with de novo DNM1 gene mutations have been reported. Conclusion: The main clinical features of DNM1 mutations include intractable seizures, intellectual disability, developmental delay, hypotonia, and developmental delay before the onset of seizures.

Abstract
PURPOSE To analyze the role of geniposide in the protein degradation of Txnip and to determine the impact of Txnip on geniposide-regulated GSIS in pancreatic INS-1 cells. METHODS The content of Txnip protein was measured by western blot; insulin content and glucose uptake were determined by ELISA; and knockdown of Txnip was the method of RNA interference. RESULTS Glucose induces a rapid increase in Txnip protein, and geniposide accelerates the degradation of Txnip via proteasome pathway in the presence of high glucose (25 mM) in INS-1 pancreatic β-cells. And MG132, a proteasomal inhibitor, potentiates glucose uptake, metabolism (ATP production) and glucose-stimulated insulin secretion (GSIS) in high-glucose (25 mM)-treated INS-1 cells, but geniposide significantly prevents these effects. Furthermore, the combination of geniposide and Txnip knockdown shows substantial synergistic effects to reduce glucose uptake, metabolism and GSIS in high-glucose (25 mM)-treated INS-1 cells. CONCLUSIONS Txnip protein played an essential role in glucose uptake, metabolism and GSIS, and geniposide could accelerate the degradation via proteasome pathway in high-glucose-treated pancreatic INS-1 cells.
