Abstract
Adoptive cell therapy with tumor-infiltrating T cells (TILs) has generated exciting clinical trial results for the treatment of unresectable solid tumors. However, solid tumors remain difficult targets for adoptively transferred T cells, due in part to poor migration of TILs to the tumor, physical barriers to infiltration, and active suppression of TILs by the tumor. Furthermore, a highly skilled team is required to obtain tumor tissue, isolate and expand the TILs ex vivo, and reinfuse them into the patient, which drives up costs and limits patient access. Here, we describe a cell-free polymer implant designed to recruit, genetically reprogram and expand host T cells at tumor lesions in situ. Importantly, the scaffold can be fabricated on a large scale and is stable to lyophilization. Using a mouse breast cancer model, we show that the implants quickly and efficiently amass cancer-specific host lymphocytes at the tumor site in quantities sufficient to bring about long-term tumor regression. Given that surgical care is the mainstay of cancer treatment for many patients, this technology could be easily implemented in a clinical setting as an add-on to surgery for solid tumors. Furthermore, the approach could be broadened to recruit and genetically reprogram other therapeutically desirable host cells, such as macrophages, natural killer cells or dendritic cells, potentially boosting the antitumor effectiveness of the implant even more.

Abstract
The unique metal-insulator transition of VO2 is very suitable for dynamic electromagnetic (EM) regulation materials due to its sharp change in electrical conductivity. Here, we have developed an off/on switchable electromagnetic interference (EMI) shielding composite by interconnecting VO2 nanowires (NWs) in poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) to form conductive networks, resulting in outstanding performance at the X and Ku bands with maximum change values of 44.8 and 59.4 dB, respectively. The unique insulator-to-metal transition (IMT) of VO2 NWs has dominated the variation of polarization loss (εp″) and conductivity loss (εσ″) for the composites, which is the mechanism of EMI shielding switching between off and on states. Furthermore, the composite exhibits good cycling stability of the off/on switchable EMI shielding performance and has excellent mechanical properties, especially with 200 times abrasion resistance without obvious weight loss. This study provides a unique approach for dynamic switching of EM response with the potential to construct practical intelligent EM response systems for next-generation smart electromagnetic devices in various scenarios.

Abstract
The study examined the relationship between financial remittances and health outcomes in 45 sub-Saharan African countries (SSA) using data obtained from the World Development Indicator (WDI) over the period 1990 to 2021. Because of the issue of endogeneity, the System Generalized Method of Moments (SGMM) was adopted to analyze the impact of remittances on life expectancy and infant mortality respectively. The results showed that contrary to expectations, remittances did not significantly improve life expectancy and infant mortality rate in SSA. The life expectancy in the previous year, has a statically significant impact on life expectancy at birth for the current year. Also, the lagged value of infant mortality rate significantly increased under five mortality. Therefore, the study recommends that governments in SSA sub-region should evolve policies aimed at guiding recipients of remittances towards effective utilization with a view to improving social welfare and health outcomes.

Abstract
With the continuous development of electronic skin (e-skin), multifunctional e-skin is approaching, and in some cases even surpassing, the capabilities of real human skin, which has garnered increasing attention. Especially, if e-skin processes eye's function, it will endow e-skins more powerful advantages, such as the vision reparation, enhanced security, improved adaptability and enhanced interactivity. Here, we first study the photodetector based on CsPbBr3 quantum dots film and the pressure sensor based on PEDOT: PSS-coated cellulose paper, respectively. On the base of these two kinds of sensors, a light/pressure bifunctional sensor was successfully fabricated. Finally, flexible bifunctional sensors were obtained by using a flexible interdigital electrode. They can simultaneously detect light and pressure stimulation. As e-skin, a high photosensitivity with a switching ratio of 168 under 405 nm light at a power of 40 mW/cm2 was obtained and they can also monitor human motions in the meantime. Our work showed that the strategy to introduce perovskite photodetectors into e-skins is feasible and may open a new way for the development of flexible multi-functional e-skin.

Abstract
Objective: To investigate the expression and clinical significance of plasma methylated SEPT9 (mSEPT9) gene in patients with primary liver cancer. Methods: 393 cases who visited our hospital from May 2016 to October 2018 were selected. Among them, 75 cases were in the primary liver cancer (PLC) group, 50 cases were in the liver cirrhosis (LC) group, and 268 cases were in the healthy control group (HC). The three groups' positive rates of mSEPT9 expression in the peripheral plasma were detected by the polymerase chain reaction (PCR) fluorescent probe method. The correlational clinical features of liver cancer were analyzed. At the same time, the electrochemiluminescence detection method was used to compare the AFP positive rate. Statistical analysis was conducted using chi-square tests or continuity-corrected chi-square tests. Results: 367 cases actually had valid samples. There were 64, 42, and 64 cases in the liver cancer group, cirrhosis group, and healthy control group, respectively. Among them, 34 cases of liver cancer were verified from pathological tissues. The positive rate of plasma mSEPT9 was significantly higher in the liver cancer group than that in the liver cirrhosis and healthy control groups [76.6% (49/64), 35.7% (15/42), and 3.8% (10/261), respectively], and the differences were statistically significant (χ (2) = 176.017, P < 0.001). The sensitivity of plasma mSEPT9 detection (76.6%) was significantly better in liver cancer (76.6%) than that of AFP patients (54.7%), and the difference was statistically significant (χ (2) = 6.788, P < 0.01). Compared with the single detection, the sensitivity and specificity of plasma mSEPT9 combined with AFP were significantly improved (89.7% vs. 96.3%, respectively). Patients with liver cancer aged≥50 years, with clinical stage II or above, and those with pathological signs of moderate to low differentiation had higher levels of plasma mSEPT9 positive expression, and the differences were statistically significant (χ (2) = 6.41, 9.279, 6.332, P < 0.05). During the follow-up period, the survival time of liver cancer patients with positive plasma mSEPT9 expression was significantly shorter than that of those with negative expression (310 ± 26 days vs. 487 ± 59 days, respectively), with statistically significant differences (Log Rank P = 0.039). Conclusion: In China, the positive rate of plasma mSEPT9 detection in liver cancer patients is higher than that of AFP in relation to age, clinical stage, and degree of tissue differentiation; additionally, it has certain survival predictive values. As a result, detecting this gene has important clinical significance and potential clinical application value in the non-invasive diagnosis and prognosis assessment of patients with primary liver cancer.

Abstract
BACKGROUND It was demonstrated that external stress, such as in vitro maturation (IVM) and vitrification process can induce significantly reduced development capacity in oocytes. Previous studies indicated that antioxidants play a pivotal part in the acquisition of adaptation in changed conditions. At present, the role of the natural potent antioxidant PCB2 in response to IVM and vitrification during ovine oocyte manipulation has not been explored. OBJECTIVE To investigate whether PCB2 treatment could improve the developmental potential of ovine oocytes under IVM and vitrification stimuli. MATERIALS AND METHODS The experiment was divided into two parts. Firstly, the effect of PCB2 on the development of oocytes during IVM was evaluated. Un-supplemented and 5 ug per mL PCB2-supplemented in the IVM solution were considered as control and experimental groups (C + 5 ug per mL PCB2). The polar body extrusion (PBE) rate, mitochondrial membrane potential (MMP), ATP, reactive oxygen species (ROS) levels and early apoptosis of oocytes were measured after IVM. Secondly, we further determine whether PCB2 could improve oocyte quality under vitrification stress. The survival rate, PBE rate and early apoptosis of oocytes were compared between fresh group, vitrified group and 5 ug per mL PCB2-supplemented in the IVM solution after vitrification (V + 5 ug per mL PCB2). RESULTS Compared to the control group, adding PCB2 significantly increased PBE rate (79.4% vs. 62.8%, P < 0.01) and MMP level (1.9 +/- 0.08 vs. 1.3 +/- 0.04, P < 0.01), and decreased ROS level (47.1 +/- 6.3 vs. 145.3 +/- 8.9, P < 0.01). However, there was no significant difference in ATP content and early apoptosis. Compared to the fresh group, vitrification significantly reduced oocytes viability (43.0% vs. 90.8%, P < 0.01) as well as PBE rate (24.2% vs. 60.6%, P < 0.05). However, 5 ug per mL PCB2-supplemention during maturation had no effect on survival, PBE or early apoptosis in vitrified oocytes. CONCLUSION PCB2 could effectively antagonise the oxidative stress during IVM and promote oocyte development. DOI: 10.54680/fr23210110412.

Abstract
Objective: To analyze the related factors of worsening renal function (WRF) in patients with acute right ventricular myocardial infarction (RVMI) during hospitalization. Methods: A total of 98 patients with acute RVMI admitted to the emergency comprehensive ward of Beijing Anzhen Hospital from August 2011 to January 2020 were enrolled in this cross-sectional study. According to the situation of WRF, the patients were divided into non-WRF group (76 cases) and WRF group (22 cases). WRF was defined as ≥0.3 mg/dL increase in serum creatinine level from baseline on day 6 of hospitalization (if hospital stay<6 days, it was at discharge). Baseline data, intravenous fluid infusion, diuretic and significant positive balance of patients' intake and output volume [any 24 h intakes and outputs ≥1 000 ml or any consecutive 72 h intakes and outputs ≥2 000 ml within 6 d of hospitalization (if hospitalization<6 d, it was from admission to discharge)] were obtained, and the differences of above indicators between the two groups were analyzed. Multiple logistic regression model was used to analyze the related factors of WRF. Results: The ages of patients in WRF group and non-WRF group were 60 (50, 68) and 63 (52, 72) years, and the male proportions were 63.6% (14 cases) and 76.3% (58 cases), respectively, and there was no significant difference (all P>0.05). The proportion of positive balance was 31.8% (7 cases) in WRF group, which was higher than 14.5% (11 cases) in non-WRF group (P=0.034). The rate of loop diuretic use in WRF group was 4.5% (1 case), lower than that in non-WRF group 10.5% (8 cases) (P=0.027). After adjusting for age, sex, baseline estimated glomerular filtration rate (eGFR), preoperative isoproterenol/temporary pacemaker/atropine use, significant positive balance of intake and output volume, and loop diuretic use, it was found that eGFR≥60 ml·min-1·1.73 m-2 and significant positive balance were associated with WRF, the OR (95%CI) were 0.71 (0.62-0.86) and 1.21 (1.02-1.43) (both P<0.05); After eliminating the variable of significant positive balance in the above model, loop diuretic use was found to be a correlation factor for WRF, with an OR (95%CI) of 0.89 (0.72-0.97) (P<0.05). Conclusions: Significant positive balance of intake and output volume during hospitalization in patients with acute RVMI is a risk factor for WRF on day 6 or at discharge. In the presence of a significant positive balance, loop diuretic use is a protective factor for WRF.

Abstract
Objective: To analyze the clinical characteristics of 6 children with TTC21B-related nephronophthisis to provide reference for early clinical diagnosis. Methods: The general condition, clinical manifestations, laboratory tests and other clinical data of 6 children from 4 families diagnosed with nephronophthisis by genetic testing in Shanghai Children's Hospital from January 2015 to December 2020 were analyzed retrospectively. Results: A total of 6 children (3 males and 3 females) developed proteinuria and progressive renal dysfunction in early infancy. The onset age of proteinuria was 18 (6, 25) months. The age at the onset of renal impairment was 22 (10, 36) months. All 6 children progressed to end-stage renal disease (ESRD) within 10 (4, 65) months of onset. Five children had hypertension, 3 children with abnormal liver function, 2 children with visceral translocation and 1 child with growth retardation. The genetic results suggested that all children carried variations TTC21B gene p.C518R. Conclusions: Children with TTC21B gene p.C518R nephronophthisis had proteinuria and progressed to ESRD at the early stage of life. These nephronophthisis patients commonly presented with liver and renal dysfunction.

In this work, its derivatives, namely four D-A shaped triphenylamine or biphenylamine endcapped indenone spirofluorene (SFD-TPA, SFD-OMeTPA, SFD-TAD, and SFD-OMeTAD), were designed and synthesized. With the introduction of electron-donating moieties and the extension of conjugation length, a series of changes in photophysical and electrochemical properties could be detected. Notably, in comparison with the optical gap (2.96 eV) of the reported spiro-OMeTAD, SFD-OMeTAD presents an optical gap as low as 1.87 eV. Moreover, density functional theory simulations were employed to further investigate their geometric and electronic structures. Finally, steady-state photoluminescence measurements proved the efficient charge separation and collection processes at the perovskite/HTM interface. It can be predicted that all four compounds with enhanced sunlight absorption capability and suitable frontier energy levels can be used as hole-transporting materials for perovskite solar cells.

Abstract
Bispecific T-Cell Engagers (BiTEs) are effective at inducing remission in hematologic cancers, but their use in solid tumors has been challenging due to their extreme potency and on-target, off-tumor toxicities in healthy tissue. Their deployment against solid tumors is further complicated by insufficient drug penetration, a hostile tumor microenvironment, and immune escape. To address these challenges, we developed targeted nanocarriers that can deliver in vitro-transcribed mRNA encoding BiTEs to host myeloid cells – a cell type that is actively recruited into the tumor microenvironment. We demonstrate in an immunocompetent mouse model of ovarian cancer, that infusion of these nanoparticles directs BiTE expression to tumor sites, which reshapes the microenvironment from suppressive to permissive and triggers disease regression without systemic toxicity. In contrast, conventional injections of recombinant BiTE protein at doses required to achieve anti-tumor activity, induced systemic inflammatory responses and severe tissue damage in all treated animals. Implemented in the clinic, this in situ gene therapy could enable physicians – with a single therapeutic – to safely target tumor antigen that would otherwise not be druggable due to the risks of on-target toxicity and, at the same time, reset the tumor milieu to boost key mediators of antitumor immune responses.

Abstract
Objective: To understand the current status of screening, diagnosis, and treatment and analyze the factors influencing micro-elimination strategy, so as to achieve hepatitis C elimination in hospital. Methods: Anti-HCV and HCV RNA test results of patients from October 2017 to September 2020 were retrospectively analyzed. Anti-HCV positive rates and factors influencing different genders, ages, places of residence and departments were analyzed. After comparing anti-HCV-positive patients with HCV RNA-positive patients with duplicate entries in "Name" and "Date of birth", the data were divided into three categories: anti-HCV positive without HCV RNA test, HCV RNA positive in single test, and HCV RNA positive many times in multiple tests. The above three types of patients were followed-up by telephone. According to the hospital follow-up results, current status of diagnosis and treatment and the factors influencing the micro-elimination strategy of hepatitis C were studied and analyzed. The comparison of data between groups were performed using χ(2) or χ(2) continuity-correction test. Results: Anti-HCV positive detection rate was 1.34% (899/66 866). The positive rate of male patients aged 40 and over residing in cities was significantly higher than female patients under 40 years old residing in rural areas, and the difference was statistically significant (χ(2) = 55.178, 264.11, 36, 351, P < 0.05). There were 90 (10.02%) and 809 cases (89.98%) in outpatient and inpatient departments, respectively, with no statistically significant difference between the two (χ(2) = 0.002, P > 0.05). The total number of anti-HCV positive cases were 196 in Gastroenterology (22.0%), 75 in Respiratory and Critical Care Medicine (8.3%), 74 in Neurology (8.2%), 63 in Orthopedics (7.0%) and 55 in Endocrinology departments (6.1%), and the difference in the positive rate among different departments were also statistically significant (χ(2) = 271.585, P < 0.05). Among the 480 cases who were followed-up, 215 (44.79%) were lost to follow-up, 84 cases (39.07%) were unregistered, 77 cases (16.04%) were untreated, 15 cases (19.48%) were unaware of their state of illness, 46 cases (59.74%) were diagnosed without concern, 16 cases (20.78%) were diagnosed but did not take medicine, 60 cases were under treatment, and 29 cases were mostly on counterfeit drugs (48.33%). Conclusion: Comprehensive diagnosis and treatment education to non-specialist clinicians and timely manner regular follow-up of patients is a key factor and an important link to formulate a simple, easy and sustainable model to improve the efficiency of screening, diagnosis, and treatment of hepatitis C micro-elimination strategy in hospital. In addition, it will also play an important role in achieving the strategic goal of "eliminating hepatitis C as a public health threat by 2030".

Abstract
The ability of myeloid regulatory cells (MRCs) to control immune responses and to promote tolerance has prompted enormous interest in exploiting them therapeutically to treat inflammation, autoimmunity, or to improve outcomes in transplantation. While immunomodulatory small-molecule compounds and antibodies have provided relief for some patients, the dosing entails high systemic drug exposures and thus increased risk of off-target adverse effects. More recently, MRC-based cell-therapy products have entered clinical testing for tolerance induction. However, the elaborate and expensive protocols currently required to manufacture engineered MRCs ex vivo put this approach beyond the reach of many patients who might benefit. A solution could be to directly program MRCs in vivo. Here we describe a targeted nanocarrier that delivers in vitro-transcribed mRNA encoding a key anti-inflammatory mediator. We demonstrate in models of systemic lupus erythematosus that infusions of nanoparticles formulated with mRNA encoding glucocorticoid-induced leucine zipper (GILZ) effectively control the disease. We further establish that these nanoreagents are safe for repeated dosing. Implemented in the clinic, this new therapy could enable physicians to treat autoimmune disease while avoiding systemic treatments that disrupt immune homeostasis.

Abstract
Stimuli-responsiveness is an important characteristic that show promising potential in various applications. Herein, a novel ZIF-8-on-Tb-dpn (H3dpn = 5-(2',4'-dicarboxylphenyl)nicotic acid) heterostructure is constructed using a heteroepitaxial strategy combining the chemical-responsive (antibiotics) and light-responsive behaviors. The pyridine nitrogen of Tb-dpn acts as an anchor site for Zn2+, which helps to overcome the limit of lattice mismatch between two metal-organic frameworks (MOFs) and promotes the growth of ZIF-8 nanocrystals. Based on the synergy effect of two MOFs, ZIF-8-on-Tb-dpn exhibits an efficient turn-off response toward tetracycline and chloramphenicol via competitive absorption, Förster resonance energy transfer, and photoinduced electron transfer processes with limit of detection values of 5.6 and 37.6 nM, respectively, which are three- to -fivefold lower than those of Tb-dpn. Moreover, the nanocage of ZIF-8 is utilized to encapsulate photochromic spiropyran (SP) molecules and realize the reversible conversion between SP and merocyanine (MC) under visible light and ultraviolet light. The MC form is accompanied with strong adsorption at 555 nm, which can erase the emission of Tb3+. Therefore, a reversible invisible anticounterfeiting pattern is designed with SP ⊂ ZIF-8-on-Tb-dpn for information anticounterfeiting. The excellent stimuli-responsive ability makes the luminescent platform a potential candidate in luminescence applications.

Abstract
Accurate hydrophobicity adjustment of single-phase material is quite challenging and meaningful for water treatment. Here, a strategy combining crystal morphology regulation and post-synthetic modification is reported based on a novel metal-organic framework (MOF, Eu-bdo-COOH, H4bdo = 2,5-bis(3,5-dicarboxylphenyl)-1,3,4-oxadiazole). The hydrophobicity is regulated by crystal size and morphology regulation, and a rough microspherical MOF is successfully synthesized. Meanwhile, the obtained MOF microspheres exhibit high water, chemical, and thermal stability. The post-synthetic modification of alkyl chains achieves fine-tuning of hydrophobicity of MOF microspheres. The static water contact angles can controllably range from 43 to 142°, and the amylamine-modified MOF (AM) obtains the strongest hydrophobicity. In addition, a superhydrophobic aerogel is constructed with AM microspheres and reduced graphene oxide (rGO) for efficient oil-water separation. The AM-rGO aerogel (AM-rGA) exhibits fast and efficient absorption of various oily substances from water, and the adsorption capacity of dibromoethane reaches up to 14,728 wt %. This outstanding oil adsorption capacity can maintain even beyond 50 cycles by the support of the stable aerogel. The strategy of morphology regulation and post-synthetic modification provides a broad approach for the hydrophobic adjustment of numerous MOF materials.

Abstract
Abstract
Background
During transcatheter aortic/mitral valve replacement (TA/MVR), current available routes are limited due to unfavorable entry-angle, vessel-anatomy or mini-thoracotomy. Through created communication of inter-ventricular septum (C-IVS), transfemoral venous transcatheter access to left ventricle becomes feasible with the assistance of arterio-venous circuit.
Purpose
The study was conducted to investigate the feasibility and safety of transfemoral-venous transcatheter access to left ventricle through the created C-IVS in a swine model.
Methods
Via femoral artery, transcatheter puncture of mid-IVS was performed with the custom-made nickel-titanium needle (0.038-inch, needle-tip bent 60 degrees automatically associated with increased hardness when temperature was above 30°C) and 6F-sheath in 20 healthy Chinese mini-swine. Then femoral arterio-venous circuit was established through created C-IVS with hydrophilic guidewire in all swine, and femoral veno-venous circuit was further created through C-IVS and atrial septum in 4 swine. After pre-dilation of C-IVS, a 20F-sheath was introduced into left ventricle transvenously over the guidewire. Furthermore, transfemoral-venous TAVR was attempted with this approach in one swine. C-IVS was evaluated postoperatively and was further confirmed pathologically 2 months later.
Results
All transcatheter puncture of IVS was performed successfully in left ventricle and the thickness of mid-IVS was 7.67±0.98 mm. During the puncture, ventricular fibrillation occurred in one swine (successfully defibrillation) and only isolated ventricular premature beats/non-sustained ventricular tachycardia were observed in other swine. In all swine, femoral arterio-venous/veno-venous circuit was established via C-IVS, and the 20F-sheath was introduced into left ventricle safely through femoral vein and C-IVS. With the aid of vessel circuit, the 20F-sheath was further advanced into aorta in 16 swine (the entry-angle was 145.3±12.2 degrees) and into left atrium in 4 swine. After the procedure, there was one swine with moderate tricuspid regurgitation and 5 swine with mild residual shunt (2.6±0.7 mm). In addition, epicardial coronary arteries were normal in all swine. Two months later, residual shunt was still detected in 3 swine and the communication was confirmed pathologically. In other swine, there was no defect of IVS and mild replacement-scar was identified along C-IVS. In the swine underwent transfemoral-venous TAVR, prosthetic valve was deployed successfully with good function.
Conclusions
With the aid of vessel circuit, transfemoral-venous transcatheter access to left ventricle is feasible and safe via C-IVS, and transfemoral-venous TAVR was achieved successfully using this novel approach with favorable entry-angle.

Abstract
Background:Focal lymphocytic sialadenitis defined as focus score (FS) ≥1 on labial gland (LG) biopsy plays an integral role in various classification criteria of Sjögren’s syndrome (SS). However, suspected patients often hesitate to receive a biopsy; and rheumatologists hope a decision for biopsy based on a high predicted incidence of FS≥1, or against biopsy based on an absolutely low predicted incidence.Objectives:To build a decision model of LG biopsy based on B-mode ultrasonography (US) with shear-wave elastography (SWE) in patients with suspected SS.Methods:Patients who had at least one symptom of oral dryness (based on AECG questions) or had anti-SSA positive were recruited and signed a written informed consent. Bilateral parotid (PG) and submandibular glands (SMG) were examined with B-mode US which graded the echostructure of each gland on a scoring system scaled 0 to 4 (US score), and SWE which described the elasticity of glands. Then LG biopsy was performed.Results:(1)Ninety-one patients whose mean age was 43±15 years were enrolled and 93% of them were female. Anti-SSA was detected in 77 patients (85%) and 28 patients (31%) showed unstimulated whole saliva flow rate (USFR)≤0.1mL/mim. There were 57 patients (63%) showing FS≥1 on LG biopsy. Sixty-three patients (69%) were classified as primary SS, 10 patients (10%) were secondary SS, 18 patients (20%) were uCTD and one patient was RA without SS.(2)US scores were equal between PG and SMG in 59 patients (65%), while the rest patients showed different US scores between two glands: 7 patients (8%) showed higher US scores in PG and 25 patients (27%) showed higher scores in SMG. In each pair of glands US scores were equal. SWE values in PG or SMG of US score 1, 2 or 3 were significantly higher than those of US score 0, while SWE values in glands of US score 4 became declined and showed no significant difference from those with US score 0 (Figure 1A).(3)Heatmap showed US scores in either major salivary gland of patients with FS≥1 on LG biopsy were significantly higher than those with FS<1 (all p<0.001, Figure 1B). ROC curve showed a total US score (including bilateral PG and SMG) ≥9 and a total SWE value (including bilateral PG and SMG)≥30 could significantly recognize patients with FS≥1, respectively with specificity of 100% and 93% (Figure 1C). In this cohort, among 51 patients with a total US score ≥9 and/or a total SWE value≥30, 49 patients (96%) showed FS≥1 on LG biopsy; while two outliers showed total US scores were both 8 although combined SWE values≥30. Other 29 patients showed total US scores≤6 with total SWE values <30 and only one patient (3%) showed FS≥1 on LG biopsy. The remaining 11 patients showed total US scores were 8 with total SWE values <30 and 64% of them (n=7) showed FS≥1.Conclusion:A preliminary decision model of LG biopsy based on B-mode US with SWE in patients with suspected SS were built in Table 1. For example, rheumatologists should reassess the need for biopsy if the incidence of FS≥1 would be <5%. Another cohort of patients with suspected SS is needed for further validation.Table 1.A preliminary decision model of LG biopsy based on B-mode US with SWE in patients with suspected SSAlgorithm*Comments on the decision of LG biopsyA total US score≥9 and/or a total SWE≥30The specificity of FS≥1 on biopsy is >93%. Biopsy is recommended. In some special cases (e.g. contraindicated to biopsy), this item is a potential alternative to LG biopsy.A total US score 7~8 with a total SWE <30It is hard to predict the result of FS, so biopsy is strongly recommended.A total US score≤6 with a total SWE <30The incidence of FS≥1 would be <5%. Rheumatologists should reassess the need for biopsy.References:NoneDisclosure of Interests:None declared

Abstract
In this paper, we present a facile approach to enhance the efficiency and stability of perovskite solar cells (PSCs) by incorporating perovskite with microporous indium-based metal-organic framework [In12O(OH)16(H2O)5(btc)6]n (In-BTC) nanocrystals and forming heterojunction light-harvesting layer. The interconnected micropores and terminal oxygen sites of In-BTC allow the preferential crystallization of perovskite inside the regular cavities, endowing the derived films with improved morphology/crystallinity and reduced grain boundaries/defects. Consequently, the In-BTC-modified PSC yields enhanced fill factor of 0.79 and power conversion efficiency (PCE) of 20.87%, surpassing the pristine device (0.76 and 19.52%, respectively). More importantly, over 80% of the original PCE is retained after 12 days of exposure to ambient environment (25 °C and relative humidity of ~ 65%) without encapsulation, while only about 35% is left to the pristine device.

Abstract
This research used Lewis acid tris(pentafluorophenyl)borane (BCF) as a p-type dopant and a light soaking (LS) treatment to improve the conductivity of poly(triarylamine) (PTAA). Specifically, the conductivity of PTAA films was improved by two orders of magnitude using BCF as a p-type dopant, and the conductivity of BCF-doped PTAA films could be further improved by using the LS treatment on its solution. The working mechanism of the formation of frustrated Lewis pairs between BCF and PTAA was proposed to explain the BCF doping and LS treatment effects on the hole transport property of PTAA. When 5 min LS-PTAA films with 8 wt % BCF were used as the hole transport layer in p-i-n planar heterojunction perovskite solar cells, a maximum power conversion efficiency of 17.12% was achieved. This work provides a deep understanding of the enhancement of the conductivity of PTAA by the BCF doping and LS treatment. In addition, a convenient and quick LS method was explored to improve the conductivity of the PTAA hole transport material. Our findings may help in improving the hole transport properties of other organic photoelectric materials and devices.

Abstract
Metal-organic complexes (MOCs) are considered as excellent precursors to prepare carbon materials, due to the fact that heteroatoms and functional groups can be naturally reserved in the resulting carbon materials through the carbonization. Herein, micromesoporous nitrogen-doped carbons MPNC-1 and MPNC-2 are successfully obtained by direct carbonization (800 °C, KOH activation) of metal-organic complexes DQA-1 and DQA-2. MPNC-1 and MPNC-2 exhibit high BET surface area (2368.9 and 2327.6 m2 g-1), pore volume (1.95 and 1.89 cm3 g-1), and N contents (17.2% and 12.3%). At 25 °C and 1 bar, MPNC-1 and MPNC-2 show high CO2 adsorption of 7.53 and 6.58 mmol g-1, the estimated CO2/N2 selectivity are 20.5 and 22.6, indicating excellent promise for practical CO2 adsorption and separation applications. Theoretical calculation indicates carbon surfaces with pyridinic-N, pyrrolic-N, and graphitic-N coexistence could strongly change the local electronic distribution and electrostatic surface potential, enhancing the CO2 adsorption with adsorption energy of -58.96 kJ mol g-1. Theoretical calculation also highlights that CO2 adsorption mechanism is electrostatic interaction with a large green isosurface between CO2 molecules and the carbon surface.

Abstract
Objective: To explore the role and mechanism of 2-deoxyglucose (2-dg) in reversing osimertinib- acquired resistance of non-small cell lung cancer(NSCLC)cell line. Methods: The NSCLC line H1975 (purchased from the American Type Culture Collection) was conducted by induction method in vitro to construct the osimertinib-resistance NSCLC cell line H1975-OR. The osimertinib-resistance of H1975-OR cell line was examined by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, colony-formation assay, Ki67 incorporation assay and the expression of apoptosis-related protein. The glycolysis level was assayed by the lactic acid production measured in the culture medium supernatant of H1975 and H1975-OR. The expression of glycolysis key enzymes (HK2, GLUT1, P-PKM2) and apoptosis-related protein (BIM, Bcl-2) were detected by Western blot. The cells were divided into control group, 2-deoxyglucose (4 mmol/L) monotherapy group, osimertinib (3 μmol/L) monotherapy group and 2-deoxyglucose (4 mmol/L)+ osimertinib (3 μmol/L) combination therapy group, then the apoptosis rate of cells was measured by flow cytometry to evaluate the pro-apoptotic ability of drugs. Date were analyzed by Independent-Samples t-test using SPSS 16.0 statistical software. Results: The glycolysis level of osimertinib-sensitive cell line H1975 was lower than that of osimertinib-resistance cell line H1975-OR [the yield of lactic acid, respectively, was (21.0±0.9) and (26.5±2.8) mmol·L(-1)·10(4)cells(-1), P<0.05]. The osimertinib- acquired resistance of H1975-OR could be reversed by 4 mmol/L 2-deoxyglucose(the IC(50) value of osimertinib in H1975-OR cell line decreased from (7.0±1.9) μmol/L to (1.4±0.1) μmol/L, which was close to the IC(50) value of osimertinib in H1975 cell line (1.0±0.2) μmol/L. The apoptosis rate of H1975-OR was significantly higher in 2-deoxyglucose + osimertinib combination therapy group (26.7±2.4)%, compared to control group (5.1±0.7)%, 2-deoxyglucose monotherapy group (6.1±2.5)% and osimertinib monotherapy group (11.4±2.7)%(all P<0.05). The expression of pro-apoptotic protein BIM in H1975-OR was significantly higher in 2-deoxyglucose+ osimertinib combination therapy group (177.8±28.1)% and the expression of anti-apoptotic protein Bcl-2 in H1975-OR was significantly lower in 2-deoxyglucose+ osimertinib combination therapy group (24.6±5.2)%, compared to control group (100±0)%, all P<0.05. Conclusion: 2-deoxyglucose can reverse the acquired resistance of NSCLC cell line to osimertinib, which may be related to the inhibition of cell glycolysis and the induction of apoptosis.

Abstract
Abstract
Background: Invasive micropapillary carcinoma (IMPC) is a rare histopathological variant of breast carcinoma and usually performs poor clinical characteristics, such as high tendency of lymph nodes metastases. But whether it has worse prognosis than invasive ductal carcinoma (IDC) is still controversial nowadays. We conducted this retrospective study to figure out the prognostic difference between IMPC and IDC, then guide therapy of IMPC ultimately.
Methods: In this study, we analyzed 327 cases of IMPC patients and 4979 cases of IDC who underwent primary resection in our institution during 2008 to 2012. By using propensity score matching, two groups were matched at a ratio of 1:1 by age, tumor size, nodal status, hormone and HER2 status to demonstrate the difference of prognosis assessed by Kaplan-Meier estimates and Cox regression analysis.
Result: After a mean follow-up of 52 months, we established the IMPC group and figured out 324 IDC patients from the control group by propensity score matching (3 IMPC patients were canceled because of data missing). The result of survival analysis indicated that women diagnosed with IMPC had no significant reduced overall survival (OS) (p = 0.752) and disease-free survival (DFS) (p = 0.578) compared with women with IDC. Multivariate Cox regression analysis revealed that IMPC was not found as an independent prognostic factor for DFS (hazard ratio [HR] = 0.858; 95% confidential interval [CI], 0.419-1.757) or OS (HR = 0.720; 95%CI, 0.353-1.469).
Conclusion: The consequence of survival analysis manifested that there was no statistically significant difference between 2 groups, and elucidated proactive or radical clinical therapy was unnecessary.

Abstract
Objective: To summarize the characteristics of cuffed-tunneled catheters insertion and investigate the values of cuffed-tunneled catheters in pediatric patients. Methods: Between March 2015 and July 2017, all the pediatric patients who received maintenance hemodialysis at least 3 consecutive months in our center were included. Sixteen cuffed-tunneled hemodialysis catheters were inserted in patients for long-term hemodialysis access. The clinical manifestations and complications were retrospectively reviewed. Results: Fifteen pediatric patients with end stage ranal disease (ESRD) were included in this study and they received 16 cuffed-tunneled catheters for long-term vascular access, including 10 males and 5 females; median age at start of catheter insertion was 11.5 (4.2-14.5) years. Body weight was (27.8±8.0)kg (16.0-39.4 kg) . The size and the length of the catheters were based on the height of patients as follows: 28 cm for (115.6±10.6) cm (102.0-130.0 cm) ,36 cm for (148.6±9.9)cm (140.0-167.0 cm) . Cuffed-tunneled catheters outcome: 10 cuffed-tunneled catheters were still functional at the end of the study; 5 catheters were removed after successful kidney transplantation. Catheter failure occurred in 1 out of 16 cuffed-tunneled catheters due to catheter-related infections. The median catheter survival time was 11.9 months (range 3.5-21.3 months). Complications of cuffed-tunneled catheters: Catheter placements operation was successful in 15 cases using ultrasound guidance. No serious complications were observed in any patients receiving catheter inserting operation. The overall rate of catheter-related infections and thrombosis/malposition was 6.3% and 18.7%, respectively. Conclusions: Ultrasound guidance is suggested in pediatric patients during the catheters insertion. The size and the length of the catheters should be based on the height of patients. Cuffed-tunneled hemodialysis catheters could be effectively used for maintenance of hemodialysis vascular access for pediatric patients with ESRD.

Abstract
Particulate matters (PMs) air pollution has become a serious environmental issue due to its great threat to human health. Herein, metal-organic complexes PBM-Zn1 and PBM-Zn2 coatings (noted as PBM-Zn-Filter) have been produced by the hot-pressing method on various substrates for the first time. Layer-by-layer PBM-Zn-Filters were also obtained through varying hot-pressing cycles. The obtained PBM-Zn-Filters with high robustness show excellent performance in PMs removal. In particular, benefiting from thelarger conjugation system, micropore structure, lower pressure drop, higher electrostatic potential ζ, and electron cloud exposed metal center of PBM-Zn2 (DFT calculations), PBM-Zn2@melamine foam-4 gives the highest removal rates, PM2.5:99.5% ± 1.2% and PM10:99.3% ± 1.1%, and the removal efficiency for capture PM2.5 and PM10 particles in cigarette smoke were both retained at high levels (>95.5%) after 24 h tests. More importantly, a homemade mask is made up by imbedding the PBM-Zn2@melamine foam-4 into a commercial breathing mask, which shows higher removal efficiency, lower pressure drop, smaller thickness, and higher quality factor than two commercial breathing masks, the PMs removal efficiencies for both PM2.5 and PM10 are 99.6% ± 0.5% and 99.4% ± 0.8%, and acceptable air resistance are demonstrated.

Abstract
Judicious structural design employing 2-quinolinecarboxaldehyde and 4-methylaniline was used to generate the Schiff base ligand (E)-4-methyl-N-((quinolin-2-yl)ethylidene)aniline (L). Five IIB complexes, namely, [ZnLCl2] (1), [ZnL(NO3)2] (2), [ZnL(OAc)2]3 (3), [CdL(OAc)2]3 (4), and [HgLCl2] (5) have been synthesized based on L. Single-crystal X-ray diffraction analysis indicates that complexes 1, 3 and 4 exhibit 3D networks, whereas 2 and 5 form 2D layers and 1D chains, respectively. TD-DFT calculations show a good correlation with the UV-vis absorption assigned to π → π* intraligand transitions. Furthermore, complexes 1-5 displayed strong greenish luminescent emissions (518-524 nm) in the aggregate state but weak emissions in solution (aggregation-induced emission enhancement), which may be due to the existence of C-HCl/O hydrogen bonding and ππ stacking interactions, resulting in restriction of intramolecular rotation (RIR). Variable-concentration 1H NMR studies suggested that the aggregates undergo intramolecular changes in conformation due to intermolecular interactions. Moreover, the emission intensity and lifetime exhibited obvious increases induced by mechanical grinding and temperature reduction, which were also attributed to AIEE properties. Subsequently, complex 1 was incorporated into poly(methyl methacrylate) (PMMA), whereby 1-PMMA exhibited enhanced emission intensity (20-fold increase in comparison with that of 1), which offers opportunities for use in plastic greenhouses to increase leaf photosynthesis.

Abstract
Introduction To evaluate the impact of intermittent portal clamping (IPC) on long-term postoperative outcomes in patients with hepatocellular carcinoma (HCC). Methods Clinical records of 355 patients underwent curative liver resection for HCC in January 2007 to December 2010 were retrospectively reviewed. According to how portal clamping was performed, patients were grouped as: IPC, n=113; other portal clamping (OPC), n=190; and no portal clamping (NPC), n=52. Results Median recurrence-free survival (RFS) was statistically significantly shorter in the IPC (39.4 months) than OPC (47.3 months, p=0.010) and NPC groups (51.4 months, p=0.008). Median overall survival (OS) was also significantly shorter with IPC (46.3 months), versus 52.9 months with OPC (p=0.022) and 56.2 months with NPC (p=0.015). Kaplan-Meier survival analysis revealed that 5-year cumulative RFS was much lower in the IPC (42.5%) than OPC (50.9%, p=0.014) and NPC groups (49.6%, p=0.013). Five-year cumulative OS was also much lower in the IPC (44.9%) than OPC (58.0%, p=0.020) and NPC groups (57.7%, p=0.025). On univariate analysis, tumour grade, size and number, TNM stage, blood transfusion, vascular invasion and IPC were significantly inversely correlated with RFS and OS. On multivariate analysis, tumour size and number, blood transfusion, vascular invasion and IPC remained significant. Conclusions Our study suggests that IPC is an independent risk factor for poor long-term postoperative outcomes in patients with HCC.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous hematopoietic disorder with a poor prognosis. Abnormal DNA methylation is involved in the initiation and progression of AML. The de novo methyltransferases Dnmt3a and Dnmt3b are responsible for the generation of genomic methylation patterns. While DNMT3A is frequently mutated in hematological malignancies, DNMT3B is rarely mutated. Although it has been previously reported that Dnmt3b functions as a tumor suppressor in a mouse model of Myc-induced lymphomagenesis, its function in AML is yet to be determined. In this study, we demonstrated that deletion of Dnmt3b accelerated the progression of MLL-AF9 leukemia by increasing stemness and enhancing cell cycle progression. Gene profiling analysis revealed upregulation of the oncogenic gene set and downregulation of the cell differentiation gene set. Furthermore, loss of Dnmt3b was able to synergize with Dnmt3a deficiency in leukemia development. Taken together, these results demonstrate that Dnmt3b plays a tumor suppressive role in MLL-AF9 AML progression, thereby providing new insights into the roles of DNA methylation in leukemia development.

Abstract
Leukemia often results in severe anemia, which may significantly contribute to patient mortality and morbidity. However, the mechanisms underlying defective erythropoiesis in leukemia have not been fully elucidated. In this study, we demonstrated that insufficient erythropoiesis in an immunocompetent acute myeloid leukemia (AML) murine model was due to reduced proliferation of megakaryocyte erythroid progenitors and increased apoptosis of erythroblasts. Colony-forming cell assays indicated that the leukemic bone marrow (BM) plasma inhibited erythroid colony formation, whereas they had no inhibitory effect on other types of colonies. Cytokine array analysis demonstrated that the chemokine CCL3 was elevated in the plasma of AML mice and patients. CCL3 inhibited erythroid differentiation of hematopoietic stem cells, common myeloid progenitors and especially megakaryocytic-erythroid progenitors. Administration of the CCR1 antagonist partially recovered the yield of erythroid colonies in the presence of CCL3 or leukemic BM plasma. Mechanistically, we observed an increase of p38 phosphorylation and subsequent downregulation of GATA1 after CCL3 treatment. Furthermore, knockdown of CCL3 attenuated leukemic progression and alleviated anemia. Therefore, our results demonstrate that elevated CCL3 in the leukemic environment suppresses erythropoiesis via CCR1-p38 activation, suggesting a novel mechanism for the erythroid defects observed in leukemia.

Abstract
Human immunodeficiency virus (HIV)-related neuropathic pain is a debilitating chronic condition that is severe and unrelenting. Despite the extensive research, the exact neuropathological mechanisms remain unknown, which hinders our ability to develop effective treatments. Loss of GABAergic tone may play an important role in the neuropathic pain state. Glutamic acid decarboxylase 67 (GAD67) is one of isoforms that catalyze GABA synthesis. Here, we used recombinant herpes simplex virus (HSV-1) vectors that encode gad1 gene to evaluate the therapeutic potential of GAD67 in peripheral HIV gp120-induced neuropathic pain in rats. We found that 1) subcutaneous inoculation of the HSV vectors expressing GAD67 attenuated mechanical allodynia in the model of HIV gp120-induced neuropathic pain, 2) the anti-allodynic effect of GAD67 was reduced by GABA-A and-B receptors antagonists, 3) HSV vectors expressing GAD67 reversed the lowered GABA-IR expression, and 4) the HSV vectors expressing GAD67 suppressed the upregulated mitochondrial superoxide and Wnt5a in the spinal dorsal horn. Taken together, our studies support the concept that recovering GABAergic tone by the HSV vectors may reverse HIV-associated neuropathic pain through suppressing mitochondrial superoxide and Wnt5a. Our studies provide validation of HSV-mediated GAD67 gene therapy in the treatment of HIV-related neuropathic pain.

Abstract
Degeneration of normal hematopoietic cells is a shared feature of malignant diseases in the hematopoietic system. Previous studies have shown the exhaustion of hematopoietic progenitor cells (HPCs) in leukemic marrow, whereas hematopoietic stem cells (HSCs) remain functional upon relocation to non-leukemic marrow. However, the underlying cellular mechanisms, especially the specific niche components that are responsible for the degeneration of HPCs, are unknown. In this study, we focused on murine bone mesenchymal stem cells (MSCs) and their supporting function for normal hematopoietic cells in Notch1-induced acute T-cell lymphocytic leukemia (T-ALL) mice. We demonstrate that the proliferative capability and differentiation potential of T-ALL MSCs were impaired due to accelerated cellular senescence. RNA-seq analysis revealed significant transcriptional alterations in leukemic MSCs. After co-cultured with the MSCs from T-ALL mice, a specific inhibitory effect on HPCs was defined, whereas in vivo repopulating potential of normal HSCs was not compromised. Furthermore, osteoprotegerin was identified as a cytokine to improve the function of T-ALL MSCs and to enhance normal HPC output via the p38/ERK pathway. Therefore, this study reveals a novel cellular mechanism underlying the inhibition of HPC generation in T-ALL. Leukemic MSCs may serve as a cellular target for improving normal hematopoietic regeneration therapeutically.
