Abstract
OBJECTIVE To investigate the influence of long non-coding ribonucleic acid (lncRNA) small nucleolar host gene 20 (SNHG20) on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) cells through the Wnt/β-catenin signaling pathway. PATIENTS AND METHODS The human NSCLC cells were cultured and lncRNA SNHG20 was inhibited using si-SNHG20 and overexpressed using SNHG20-OE. Then, flow cytometry was used to detect the apoptotic rate. The targets of lncRNA SNHG20 were detected via dual-luciferase reporter gene assay, and the changes in the protein level were detected via Western blotting. RESULTS LncRNA SNHG20 was highly expressed in the cancer tissues and serum of patients with NSCLC. LncRNA SNHG20 could promote the proliferation and inhibit the apoptosis of NSCLC cells. LncRNA SNHG20 could bind to micro RNA (miR)-197 in a targeted manner. Besides, nuclear translocation of β-catenin was significantly enhanced after transfection of miR-197. After the down-regulation of miR-197 by small interfering RNA (siRNA), the key molecules TCF and LEF1 of the Wnt/β-catenin pathway were significantly down-regulated. CONCLUSIONS LncRNA SNHG20 promotes the proliferation and inhibits the apoptosis of NSCLC cells by targeting miR-197 through the Wnt/β-catenin signaling pathway.

Abstract
Cardiac fibrosis, featuring abnormally elevated extracellular matrix accumulation, decreases tissue compliance, impairs cardiac function and accelerates heart failure. Mounting evidence suggests that the ubiquitin proteasome pathway is involved in cardiac fibrosis. In the present study, ubiquitin-specific protease 2 (USP2) was identified as a novel therapeutic target in cardiac fibrosis. Indeed, USP2 expression was increased in angiotensin II-induced primary cardiac fibroblasts (CFs) from neonatal rats. In addition, USP2 inhibition suppressed CFs proliferation, collagen synthesis and cell cycle progression. Furthermore, USP2 interacted with β-catenin, thereby regulating its deubiquitination and stabilization in CFs. To sum up, these findings revealed that USP2 has a therapeutic potential for the treatment of cardiac fibrosis.

Abstract
BACKGROUND Frail patients are increasingly vulnerable to stress, which is mainly manifested by a reduced physiologic reserve in metabolic and immune systems and neuromuscular system. Several studies found a significant association of frailty with COVID-19 severity to support the evidence for the application of frailty assessment. However, there were contradictory results in other studies. Thus we conducted a systematic review and meta-analysis to synthesize the current studies to investigate impact of frailty on COVID-19 outcomes and provide evidence-based decisions in clinical practice. OBJECTIVE We aimed to synthesize the current studies to investigate impact of frailty on COVID-19 outcomes and provide evidence-based decisions in clinical practice. DESIGN A systematic review and Meta-analysis of 16 cohort studies. PARTICIPANTS Patients with COVID-19. METHODS A systematic retrieving for potential literature was conducted in several public electronic databases, including Medline(OvidSP), EMBASE, Pubmed and Chinese databases(China National Knowledge Infrastructure,Wanfang and Weipu) on August 1, 2020.The literature research was updated on October 26, 2020. Newcastle Ottawa Scale for cohort studies was used for quality assessment. RevMan (Version 5.3) and Stata 14.0 were used to synthesize the pooled effects. RESULTS According to the predefined inclusion and exclusion criteria, sixteen studies of 4324 patients were included in the final analysis. Frailty was significantly associated with increased risk of all-cause mortality among patients with COVID-19, with pooled adjusted odds ratios of 1.81 (95% confidence intervals:1.48,2.21, I2=87.0%, P<0.001). The result was consistent in stratified analysis to according to age, patient source, definitions of frailty, study quality, and adjustment method. Frailty was significant associated with an increased risk of COVID-19 severity, admission to intensive care unit, application of invasive mechanical ventilation, long-length stay. CONCLUSIONS In this meta-analysis, we found frailty was significantly associated with an increased risk of clinical adverse events (all- cause mortality, COVID-19 severity, admission to the intensive care unit, application of invasive mechanical ventilation, long-length stay). Given the epidemic of COVID-19 and shortage of medical resources, paying more attention to screening frailty would contribute to disease management and resource allocation among patients with COVID-19.

Abstract
Background Adrenocortical carcinoma (ACC) is a rare malignancy occurring in the adrenal cortex characterized by its low incidence rate, aggressive tumor behavior with high propensity of invasion and distant metastasis, and poor prognosis. When detected, it usually appears as advanced tumor with limited treatment options. Systemic chemotherapy is the only recommended treatment option and EDP-M plus sintilimab has recently emerged as a new treatment option. In the present study, we report a case of ACC treated with EDP-M plus sintilimab. Case Description We present a 30-year-old female patient with ACC and bilateral lung metastases. PET-CT scan showed multiple metastatic sites in both lungs, among which the largest one was located in the lower lobe of the right lung, with a size of 42 mm × 22 mm. A space-occupying lesion was also found in the right adrenal gland with a size of 92 mm × 51 mm. The patient was treated with EDP plus sintilimab for four cycles in our hospital and mitotane was introduced after the first cycle. Follow-ups after the second and fourth cycles found significantly reduced lung metastases with all imaging examinations indicating PR status. The patient received maintenance therapy thereafter with sintilimab plus mitotane. Until recently, the patient’s lung metastases have basically disappeared and no disease progression has been observed. The progression free survival (PFS) of this patient has been extended to about 7 months. Conclusions Although deemed as the standard chemotherapeutic regimen for advanced ACC, the efficacy of EDP-M is not satisfactory. This case study demonstrates the clinical effectiveness of EDP-M plus sintilimab in the treatment of advanced ACC with good patient tolerance, suggesting that this regimen combination can be a promising treatment option for refractory ACCs.

Abstract
Isoflurane (ISO) elicits protective effects on ischemia-induced brain injury. We investigated whether sub-anesthetic (0.7%) ISO post-conditioning attenuates the inflammation and apoptosis in oxygen-glucose deprivation (OGD)-insulted co-cultures (microglia and neurons) in vitro and the brain injury of the middle cerebral arterial occlusion (MCAO) rat. We demonstrated that ISO augmented the viability of OGD-treated microglia and neurons. ISO reduced the expression and activation of COX2 and iNOS in OGD-challenged microglia. ISO repressed the production of tumor necrosis factor-α, interleukin (IL)-1β, IL-6, IL-8, and monocyte chemoattractant protein-1 in OGD-exposed microglia. ISO also decreased nucleosomal fragmentation and caspase-3 activity but increased mitochondrial membrane potential in OGD-stimulated microglia and neurons. Mechanistically, ISO suppressed OGD-induced microglial inflammation by blocking ROS-regulated p38 MAPK/NF-κB signaling pathway and hampered OGD-triggered microglial apoptosis in a ROS- or NO-dependent fashion. In vivo results with MCAO rats were partly consistent with the in vitro observation. These findings indicate that sub-anesthetic ISO post-conditioning abates the inflammation and apoptosis in OGD-stimulated rat microglia and the apoptosis of OGD-exposed neurons and the brain injuries of MCAO rats, suggesting it as a potentially effective therapeutic approach for ischemic brain damages.

Abstract
BACKGROUND Intracranial infection after puncture of cerebral hematoma in patients with intracerebral hemorrhage is very common in the department of neurosurgery, yet the relevant risks remain unknown. We attempted to analyze the risk factors of intracranial infection after puncture of cerebral hematoma, to provide insights into the management of patients with intracerebral hemorrhage after puncture of cerebral hematoma. METHODS Patients with intracerebral hemorrhage after puncture of cerebral hematoma treated in our hospital from January 2017 to January 2020 were selected, the related characteristics of intracranial infection and no infection patients were compared. Logistic regression analyses were conducted to analyze the risk factors for intracranial infection after puncture of cerebral hematoma. RESULTS A total of 925 patients with puncture of cerebral hematoma were included. The incidence of postoperative intracranial infection was 7.03%. There were significant statistical differences between the infected group and the no infection group in the American Association of Anesthesiologists (ASA) grade, length of hospital stay, consecutive operation, duration of surgery, extra-ventricular drainage (EVD) use (all p < 0.05). There was statistically significant difference in the duration of EVD between the infection and no infection groups (p = 0.002), and there was no significant difference in the frequency of EVD insertion between the two groups (p = 0.094). The length of hospital stay≥10 days (OR1.832, 1.062-3.158), consecutive operation (OR2.158, 1.358-3.430), duration of surgery≥4 h (OR1.581, 1.031-2.425), EVD use (OR1.694, 1.074-2.670), and duration of EVD ≥ 7 days (OR2.699, 1.689-4.311) were the risk factors of intracranial infection in patients with intracerebral hemorrhage after puncture of cerebral hematoma (all p < 0.05). CONCLUSION Clinical medical workers should take corresponding preventive measures against the different risk factors for prevention of intracranial infection in patient with puncture of cerebral hematoma.

Abstract
Background:
Maintenance chemotherapeutic regimen with low toxicity is needed for
metastatic colorectal cancer. A recent patent has been issued on the spleen-strengthening and detoxification
prescription (JPJDF), a traditional Chinese herbal medicinal formula with anti-angiogenesis
effect. The clinical effect of JPJDF on the maintenance treatment of advanced colorectal cancer
has not been evaluated.
Objective:
This study aims to evaluate the effectiveness and safety of JPJDF in combination with
fluoropyrimidine compared to fluoropyrimidine alone as maintenance therapy for metastatic colorectal
cancer.
Methods:
We applied a prospective, randomized, double-blinded, single center clinical study design.
A total of 137 patients with advanced colorectal cancer were recruited. Patients received either
Fluoropyrimidine (Flu-treated group, n = 68), or Fluoropyrimidine plus JPJDF (Flu-F-treated
group, n = 69) as maintenance treatment after 6-cycle of FOLFOX4 or FOLFORI induction treatment.
The primary endpoints were Progression-Free Survival (PFS) and Overall Survival (OS).
The secondary endpoints were safety, Performance Status (PS) score and other symptoms.
Results:
The endpoint of disease progression was observed in 91.7% of patients. The PFS was 5.0
months and 3.0 months in the Flu-F-treated and Flu-treated groups, respectively. The OS was 15.0
months and 9.0 months in the Flu-F-treated and Flu-treated groups, respectively. Some common
symptoms, such as hypodynamia, anepithymia, dizziness and tinnitus and shortness of breath, were
improved in the Flu-F-treated group. There was no significant difference in the common adverse reactions
between the two groups.
Conclusion:
JPJDF and fluoropyrimidine have synergistic effect in the maintenance treatment of
mCRC.

Abstract
Multilocular cystic renal neoplasm of low malignant potential (MCRNLMP) might be benefited from nephron-sparing surgery. Contrast-enhanced computed tomography is used for the diagnosis of MCRNLMP but contrast-enhanced ultrasound has lack of nephrotoxicity and several advantages over contrast-enhanced computed tomography and contrast-enhanced magnetic resonance. The purpose of the study was to compare diagnostic parameters of preoperative contrast-enhanced ultrasound against contrast-enhanced computed tomography for the detection of MCRNLMP in patients who faced curative surgery for complex cystic renal mass.Data regarding contrast-enhanced ultrasound, contrast-enhanced computed tomography, and clinicopathological results of 219 patients who underwent curative surgery for complex cystic renal mass (Bosniak classification III or IV) were retrospectively collected and analyzed. Bosniak classification for imaging modality and the 2016 WHO criteria for clinic pathology were used for detection of MCRNLMP.Contrast-enhanced ultrasound, contrast-enhanced computed tomography, and clinicopathology were detected 68, 66, and 67 as a MCRNLMP respectively. Contrast-enhanced ultrasound and contrast-enhanced computed tomography had 30.37% and 29.27% sensitivities for the detection of MCRNLMP. While 60% and 50% specificities respectively. Bosniak classification III (P = .045) and lower mean Hounsfield unit (P = .049) were associated with the prevalence of MCRNLMP. Contrast-enhanced computed tomography was detected 6 and 7, while contrast-enhanced ultrasound detected 3 and 2 complex cystic renal mass as false positive and false negative MCRNLMP respectively. A contrast-enhanced ultrasound had 0.011 to 1.0 diagnostic confidence and contrast-enhanced computed tomography had 0.045 to 0.983 diagnostic confidence for decision making of nephron-sparing surgeries.Contrast-enhanced ultrasound may have better visualization of MCRNLMP than contrast-enhanced computed tomography.Level of Evidence: III.

Abstract
Foam cell formation process is involved in the pathogenesis of atherosclerosis (AS). Activation of this biological process depends on lipid uptake by scavenger receptors, such as CD36, SR-A and SR-B1. Among these receptors, CD36 is the principal one because it dominates roughly 50% lipid uptake in monocytes. In this study, our western blotting and RT-qPCR assays revealed that USP10 inhibition promotes the degradation of CD36 protein but does not change its mRNA level. In addition, Co-IP results showed that USP10 interacts with CD36 and stabilizes CD36 protein by cleaving poly-ubiquitin on CD36. Significantly, USP10 promotes foam cell formation. Immunofluorescence and Oil red O staining assays show that inhibition or knockdown of USP10 suppresses lipid uptake and foam cell formation by macrophages. In conclusion, USP10 promotes the development and progression of atherosclerosis through stabilizing CD36 protein expression. The regulation of USP10-CD36 may provide a significant therapeutic scheme in atherosclerosis.

Abstract
Breast cancer (BCa) has the highest incidence and mortality among malignant diseases in female worldwide. BCa is frequently caused by estrogen receptor α (ERα), a ligand-dependent receptor that highly expressed in about 70% of breast tumors. Therefore, ERα has become a well-characterized and the most effective target for treating ERα-expressing BCa (ERα+ BCa). However, the acquire resistance was somehow developed in patients who received current ERα signaling-targeted endocrine therapies. Hence, discovery of novel anti-estrogen/ERα strategies is urgent. In the present study, we identified butein as a potential agent for breast cancer treatment by the use of a natural product library. We showed that butein inhibits the growth of ERα+ BCa both in vitro and in vivo which is associated with cell cycle arrest that partially triggered by butein-induced ERα downregulation. Mechanically, butein binds to a specific pocket of ERα and promotes proteasome-mediated degradation of the receptor. Collectively, this work reveals that butein is a candidate to diminish ERα signaling which represents a potentially novel strategy for treating BCa.

Abstract
Abstract
Background
Inconsistent data support the role of CACNA1C as a disease-causing gene responsible for Brugada syndrome (BrS). As of today, the only gene consistently linked with BrS is SCN5A. Several CACNA1c genetic variants have been reported in association wirh BrS; however, due to the limited evidence, CACNA1C is not suggested for routine genetic screening for BrS.
Purpose
In this study, we carried out a systematic screening of CACNA1C gene, including a functional evaluation of the identified variants, in order to determine the yield of screening in a large series of BrS probands and to address the hypothesis that an appropriate clinical selection of patients would substantially improve the yield of genetic testing.
Methods and results
Overall 564 consecutive patients, referred for BrS genetic testing, were sequenced for CACNA1C gene. Patients were divided in two groups: discovery cohort (n=200 patients) and confirmation cohort (n=363 patients). Furthermore, analysis of the clinical phenotypes of a matched SCN5A positive BrS cohort (n=146) was included for phenotype characterization.
In the discovery cohort we identified 11 different genetic variants of whom 2 (18%) were considered as potentially causative based on ACMG guidelines. However, a large proportion (81%) was classified as variants of unknown significance (VUS). Functional evaluation of the identified variants, including pathogenic and VUS, was assessed by patch-clamp and immunofluorescence studies. Re-evaluation of the variants, including functional studies results, indicated an increase of pathogenic or likely pathogenic variants (81%) getting a yield of screening of 5% in the discovery cohort. Results from the confirmation cohort confirmed a low rate of CACNA1C carriers with a yield of screening of 2.2%.
Analysing the clinical phenotype of all CACNA1C carriers showed a significantly shorter QTc [371 ms ± 16 ms vs. 399±18 ms; p=0.000004]. Furthermore, the prevalence of CACNA1C variants was highest (12.9%) among patients with a QTc in the lowest quartile (QTc <390 ms). ROC curve showed an AUC of 0.91 for QTc a cut-off of 385 ms, suggesting a high predictive accuracy.
Conclusion
We confirmed that CACNA1C variants are not a common cause of BrS, with a yield of screening of 2–5%. However, pathogenic variants are more frequent (12.5%) in patients with a shorter QTc, suggesting a genetic testing strategy in this subgroup of BrS patients. Furthermore, our data highlights the impact of robust functional studies to improve variant classification and reduce uncertainties.

Abstract
Tanshinone IIA (Tan IIA) is a major active ingredient extracted from Salvia miltiorrhiza, which has been proved to be able to inhibit metastasis of various cancers including colorectal cancer (CRC). However, the mechanisms of anti-metastatic effect of Tan IIA on CRC are not well explored. A number of studies indicate that epithelial-to-mesenchymal transition (EMT) plays an important role in CRC metastasis, and our previous studies demonstrate that β-arrestin1could regulate EMT in CRC partly through β-catenin signaling pathway. In this work, we investigate whether Tan IIA could regulate EMT in CRC through β-arrestin1-mediated β-catenin signaling pathway both in vivo and in vitro. Our results showed that Tan IIA inhibited lung metastases of CRC cells in vivo and extended the survival time of mice with CRC. In vitro, Tan IIA increased the expression of E-cadherin, decreased the expression of Snail, N-cadherin and Vimentin, thus suppressed EMT and the migratory ability of CRC cells. Further study found that the mechanism of action of Tan IIA in regulating EMT and metastasis is associated with the suppression of β-arrestin1 expression, resulting in the increase of GSK-3β expression, reduction of β-catenin nuclear localization, thereby decreased the activity of β-catenin signaling pathway. Our data revealed a new mechanism of Tan IIA on the suppression of EMT and metastasis in CRC via β-arrestin1-mediated β-catenin signaling pathway and provided support for using Tan IIA as anti-metastatic agents in CRC.

Abstract
BACKGROUND Progressive pseudorheumatoid dysplasia is a rare skeletal dysplasia mainly caused by abnormal autosomal recessive inheritance. Although the main function of cartilage is mechanical support and the characteristics of this disease is the degradation of AC, previous studies on it had been mainly focused on clinical and genetic aspects and the mechanical behavior of the cartilage affected by PPRD is still ambiguous. In this study, we investigate the mechanics and structure of the cartilage suffered disease at multi-scale, from individual chondrocytes to the bulk-scale tissue. METHODS Depth-sensing indenter were employed to investigate the mechanics of cartilage; we performed atomic force microscope nanoindentation to investigate the cell mechanics and scanning electron microscopy were used to explore the structure feature and chemical composition. FINDINGS The elastic modulus of chondrocytes harvested from cartilage suffered from progressive pseudorheumatoid dysplasia is significantly higher than from normal cartilage, same trend were also found in tissue level. Moreover, denser collagen meshwork and matrix calcification were also observed. INTERPRETATION The elastic modulus of cartilage should closely related to its denser structure and the calcification, and may potentially be an indicator for clinical diagnosis. The stiffening of chondrocytes during PPRD progression should play a rather important role in its pathogenesis.

Abstract
Objective: This study explored the thromboembolism risk of low-risk atrial fibrillation (AF) patients (CHA2DS2-VASc score of 0 or 1 for male and 1 or 2 for female) with different clinical characteristics to provide the basis for anticoagulation decision-making in these patients. Methods: We prospectively enrolled consecutive 2 862 nonvalvular low-risk AF patients between August 2011 to December 2018 in China-AF (China Atrial Fibrillation Registry) Study, their CHA2DS2-VASc score was 0 or 1 for male and 1 or 2 for female. According to their age, sex, presence or absence of hypertension, diabetes mellitus, congestive heart failure, and vascular disease at the time of enrolling, patients were divided into CHA2DS2-VASc score 0 score group, 1 score group, and 2 score group. Patients were followed up every 6 months by outpatient clinic visit or telephone interview. The outcome was a thromboembolic event, including ischemic stroke and systemic embolism. Univariate Cox regression analysis was used to compare the thromboembolism risk between the patients with different risk factors and CHA2DS2-VASc score 0 group. Results: A total of 2 862 low-risk atrial fibrillation patients were enrolled in this study. 915 patients (32.0%) were female, and age was (55.0±10.7) years old. There were 933 patients (32.6%) in CHA2DS2-VASc score 0 group, 1 401 patients (49.0%) in score 1 group and 528 patients (18.5%) in score 2 group. During follow-up (median 1.5 years, 5 811.82 person-years), 33 cases of thromboembolic events were recorded, the annual rate of thromboembolism was 0.57% (95%CI 0.40%~0.80%). The number of thromboembolic events in patients with CHA2DS2-VASc score 0, 1 and 2 were 8, 11 and 14, respectively, and the annual thromboembolism event rates were 0.40% (95%CI 0.20%-0.81%), 0.39% (95%CI 0.22%-0.71%) and 1.34% (95%CI 0.80%-2.27%), respectively. The risk of thromboembolism of CHA2DS2-VASc score 2 group (HR=3.53, 95%CI 1.48-8.44; P=0.005), especially female patients aged 65-74 years in CHA2DS2-VASc score 2 group (HR=2.67, 95%CI 1.63-4.38; P<0.000) was significantly higher than that in patients of CHA2DS2-VASc score 0 group. Conclusion: Low-Risk Atrial Fibrillation patients with CHA2DS2-VASc score 2, especially female patients aged 65-74 years old with CHA2DS2-VASc score 2 are at higher risk of thromboembolism in low-risk AF patients. For such patients, intensified oral anticoagulant therapy might be helpful to reduce the risk of thrombolism.

Abstract
Background: Vibrio Splendidus Vs is an important aquaculture pathogen that can infect a broad host of marine organisms. In our previous study,
an antagonistic bacterium Vibrio sp. V33 that possessed inhibitory effects on the growth and virulence of a pathogenic isolate V. splendidus Vs was identified. Objectives: Here, we further explored the antagonistic substances and antagonistic effects from the viewpoint of iron competition. Materials and Methods: The main antagonistic substances in the supernatants from Vibrio sp. V33 were identified using the bioassay-guided method.
The response of V. splendidus Vs under the challenge of cell-free supernatant from Vibrio sp. V33 was determined via sodium dodecyl
sulfate-polyacrylamide gel electrophoresis and real-time reverse-transcription PCR. Results: The main antagonistic substances produced by Vibrio sp. V33 have low molecular weights, are water soluble, and are heat-stable substances.
Meanwhile, the iron uptake rate of Vibrio sp. V33 was higher than that of V. splendidus Vs. In the presence of cell-free supernatant
from Vibrio sp. V33, expressions of two functional genes, viuB and asbJ related to ferric uptake processes in V. splendidus Vs,
were up-regulated, whereas furVs coding the ferric uptake repressor was suppressed below 0.5-fold. One gene coding phosphopyruvate
hydratase does not change at mRNA level, but was up-regulated at protein level. Conclusions: Our results suggested that antagonistic effect of Vibrio sp. V33 on the pathogenic isolate V. splendidus Vs was partially due to the stronger
ability of Vibrio sp. V33 to seize iron. This cell-free supernatant from Vibrio sp. V33 created an iron-limited milieu for V. splendidus Vs,
which led to the changed expression profiles of genes that were related to iron uptake in V. splendidus Vs.

Abstract
The protein translocated intimin receptor (Tir) from enteropathogenic Escherichia coli shares sequence similarity with the host cellular immunoreceptor tyrosine-based inhibition motifs (ITIMs). The ITIMs of Tir are required for Tir-mediated immune inhibition and evasion of host immune responses. However, the underlying molecular mechanism by which Tir regulates immune inhibition remains unclear. Here we demonstrated that β-arrestin 2, which is involved in the G-protein-coupled receptor (GPCR) signal pathway, interacted with Tir in an ITIM-dependent manner. For the molecular mechanism, we found that β-arrestin 2 enhanced the recruitment of SHP-1 to Tir. The recruited SHP-1 inhibited K63-linked ubiquitination of TRAF6 by dephosphorylating TRAF6 at Tyr288, and inhibited K63-linked ubiquitination and phosphorylation of TAK1 by dephosphorylating TAK1 at Tyr206, which cut off the downstream signal transduction and subsequent cytokine production. Moreover, the inhibitory effect of Tir on immune responses was diminished in β-arrestin 2-deficient mice and macrophages. These findings suggest that β-arrestin 2 is a key regulator in Tir-mediated immune evasion, which could serve as a new therapeutic target for bacterial infectious diseases.

Abstract
INTRODUCTION Risk-prediction models for breakthrough pain facilitate interventions to forestall inadequate labour analgesia, but limited work has used machine learning to identify predictive factors. We compared the performance of machine learning and regression techniques in identifying parturients at increased risk of breakthrough pain during labour epidural analgesia. METHODS A single-centre retrospective study involved parturients receiving patient-controlled epidural analgesia. The primary outcome was breakthrough pain. We randomly selected 80% of the cohort (training cohort) to develop three prediction models using random forest, XGBoost, and logistic regression, followed by validation against the remaining 20% of the cohort (validation cohort). Area-under-the-receiver operating characteristic curve (AUC), sensitivity, specificity, and positive and negative predictive values (PPV and NPV) were used to assess model performance. RESULTS Data from 20 716 parturients were analysed. The incidence of breakthrough pain was 14.2%. Of 31 candidate variables, random forest, XGBoost and logistic regression models included 30, 23, and 15 variables, respectively. Unintended venous puncture, post-neuraxial analgesia highest pain score, number of dinoprostone suppositories, neuraxial technique, number of neuraxial attempts, depth to epidural space, body mass index, pre-neuraxial analgesia oxytocin infusion rate, maternal age, pre-neuraxial analgesia cervical dilation, anaesthesiologist rank, and multiparity, were identified in all three models. All three models performed similarly, with AUC 0.763-0.772, sensitivity 67.0-69.4%, specificity 70.9-76.2%, PPV 28.3-31.8%, and NPV 93.3-93.5%. CONCLUSIONS Machine learning did not improve the prediction of breakthrough pain compared with multivariable regression. Larger population-wide studies are needed to improve predictive ability.

Abstract
The modifications of multilayer dielectric (MLD) gratings arising from laser-induced damage using 0.6-ps and 10-ps laser pulses at 1053 nm are investigated to better understand the damage-initiation mechanisms. Upon damage initiation, sections of the affected grating pillars are removed, thereby erasing the signature of the underlying mechanisms of laser damage. To address this issue, we performed paired studies using macroscopic grating-like features that are 5 mm in width to reveal the laser-damage morphology of the different grating sections: pillar side wall, sole, and pillar top. The results suggest that, similarly to MLD coatings, there are two damage-initiation mechanisms corresponding to the different pulse durations.

Abstract
Objective: To share related knowledge and experiences with countries along the line, literature regarding current cohort studies was summarized. Distribution, establishment and development of cohort studies among large prospective general population were analyzed in 17 countries of Western Asia and the 16 countries of Central and Eastern Europe. Methods: Literature review was conducted to collect basic information on cohort studies, with descriptive study used to analyze the characteristics of these cohort studies. Results: There were 562 cohort studies with sample size as more than 1 000 stated in Western Asia and Central and Eastern Europe, including 468 (83.27%) carried out in the nation itself and 94 (16.73%) with international multicentered collaboration. According to the nature of cohort studies, 347 (61.74%) were etiologically based. As for the contents involved, 310 (55.16%) of them targeted on chronic/non-communicable diseases, 125 (22.24%) concentrated on maternal and child health. Among those on chronic/non-communicable diseases, 51 (16.45%) were on cancers and 83 (26.77%) on cardiovascular disease studies. There appeared 10 large prospective cohort studies targeting on general population, mainly ongoing in Iran and European countries, with a duration of 8-29 years, including 4 of them with sample size as more than 50 000. In terms of the contents, epidemiological investigation, physical examination and biological samples collection took the major parts. Few papers were published in 9 out of the 10 cohort studies at the early stage of those projects but the number of papers increased annually and stabilized to certain extent. Conclusions: The regional distribution of cohort studies carried out in countries from the Western Asia and Central and Eastern European areas appeared unbalanced. Contents of these designs would mainly involve etiological studies, with focus on non-communicable diseases as cancer, cardiovascular disease, diabetes, respiratory diseases, mental and psychological diseases, and maternal and infant health etc.. However, only few large prospective cohort studies would base on general population.

Abstract
A combination of pegylated interferon-alpha (peg-IFN-α) and nucleos(t)ides analogue (NA) therapy can effectively reduce hepatitis B surface antigen (HBsAg), especially in NA-experienced chronic hepatitis B (CHB) patients. However, the immune mechanism of this therapy is unclear. Forty NA-experienced CHB patients were enrolled into this study. The frequencies of peripheral blood natural killer (NK) cells, dendritic cells (DCs), CD4+ T cells, CD8+ T cells, T helper (Th) cells, regulatory T cells (Treg ), B cells and follicular T helper (Tfh) cells were evaluated by flow cytometry. Seven of the 40 patients converted to peg-IFN-α combined with NA treatment, while the other 33 continued to NA therapy. The decrease in HBsAg was more pronounced in the combination treatment group, and only patients receiving combination treatment achieved HBsAg loss. The frequency and absolute number of CD56bright NK cells in the combination treatment group increased significantly compared with the NA treatment group, whereas the CD56dim NK cells were decreased. In the NA treatment group, the proportions of CD4+ TN , CD8+ TN , CD19+ B and cytotoxic T lymphocyte antigen-4 (CTLA-4)+ CD4+ T cells were increased, while the proportions of CD4+ TEM , CD8+ TEM , CD25+ CD4+ Treg , CD25high CD4+ Treg , CD127low CD25+ Treg , programmed cell death 1 (PD-1)+ CD4+ T, PD-1+ CD8+ T, CTLA-4+ CD8+ T, CCR4+ CD25+ Treg and CCR4+ CD25high Treg cells were decreased after therapy. For NA-experienced CHB patients who achieved low HBsAg levels, combination treatment is more likely to result in HBsAg decline and HBsAg clearance by increasing the activity of CD56bright NK cells.

Abstract
The purpose of this study was to investigate the effect of desflurane (Des) pretreatment on sepsisevoked lung injury in rats and its mechanism. The rat model of sepsis-evoked lung injury was prepared using lipopolysaccharide (LPS), while rat lung mesenchymal cell (MSC) model was cultured in vitro, followed by Des pretreatment or inhibitor S31-201 culture. The degree of lung tissue injury was analyzed by Hematoxylin-eosin (HE) staining. The expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor (TNF)-α in the serum of rats were detected by enzyme-linked immunosorbent assay (ELISA). One-step terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay was utilized to determine the apoptosis levels of lung tissues and MSCs cultured in vitro. The expressions of the signal transducer and activator of transcription 3 (STAT3) pathway in rat lung tissues and MSCs were detected by Western blotting. After modeling, LPS induced the lung injury in rats, the expression levels of IL-6, IL-1β and TNF-α were up-regulated (P<0.05), the apoptosis rate was increased (P<0.05), and phosphorylated-Janus kinase 2 (p-JAK2) and phosphorylated-STAT3 (p-STAT3) protein expressions were up-regulated (P<0.05). Des pretreatment can alleviate LPS-induced lung injury, down-regulate IL-6, IL-1β and TNF-α expression levels (P<0.05), reduce apoptosis (P<0.05), and downregulate p-JAK2 and p-STAT3 protein levels (P<0.05). LPS induced an increase in apoptosis rate of MSCs (P<0.05) and the up-regulation of p-STAT3 protein expression (P<0.05). Both Des pretreatment and S31-201 inhibitor culture could reduce the apoptosis rate (P<0.05) and down-regulate p-STAT3 protein level (P<0.05). Des pretreatment can reduce sepsis-evoked lung injury in rats, which may be related to the inhibition of protein expressions of STAT3 pathway.

Abstract
OBJECTIVES Chinese adults are the biggest users of healthcare services, and understanding current trends in disability profiles is relevant to planning healthcare workforce infrastructure. We investigated the trends over time for disability and physical functional limitations from 2011 to 2015 among Chinese adults and identified the factors associated with these limitations. STUDY DESIGN We used nationally representative data from the China Health and Retirement Longitudinal Study (CHARLS); the CHARLS participants were followed up every 2 years as they moved from work to retirement with an emphasis on their health status and functional abilities. METHODS Participants aged ≥50 years from three waves of the CHARLS were included. Data were collected on physical functioning limitations, disabilities in activities of daily living (ADLs) and disabilities in instrumental activities of daily living (IADLs). Multilevel logistic regression models were used to test for changes and factors associated with limitations and disabilities between 2011 and 2015 adjusting for sociodemographic, medical history and health measures. RESULTS There were 44,447 eligible participants (mean age: 63 years; standard deviation [SD], 9 years; 51% female). After adjustment, there was no significant increase in reporting of ADLs or IADLs in the 2015 survey compared with the 2011 survey. After adjustment, there was a 26% significant increase in reporting of physical functioning limitations in the 2015 survey compared with the 2011 survey (odds ratio: 1.26; 95% confidence interval, 1.17 to 1.35). Factors associated with ADL disability were being female, being older, minimal education, no alcohol intake in the previous year, falls, fractured hip, feeling depressed and being obese. Factors associated with IADL disabilities were being female, being older, minimal education and feeling depressed. CONCLUSIONS Chinese health agencies should consider the growing need for sufficient community services infrastructure to maximise independence, particularly in the context of ageing populations.

Abstract
The incidence and mortality of breast cancer (BCa) are the highest among female cancers. There are approximate 70% BCa that are classified as estrogen receptor alpha (ERα) positive. Therefore, targeting ERα is the most significantly therapeutic schedule. However, patients with breast cancer develop resistance to ERα or estrogen (E2) antagonists such as fulvestrant and tamoxifen. In the present study, we found that L-Tetrahydropalmatine (L-THP) significantly suppressed cell proliferation in ERα+ BCa cells via inducing cell cycle arrest rather than apoptosis. Additionally, L-THP enhanced the sensitivity of ERα+ BCa cells to tamoxifen and fulvestrant. Mechanically, the application of L-THP promotes ERα degradation through accumulating ubiquitin chains on ERα. Overexpressing ERα abrogates L-THP induced-antiproliferation in ERα+ BCa cells. Collectively, our work indicates that L-THP may represent a potentially novel therapeutic medicine for ERα+ breast cancer patient.

Abstract
Fe3 O4 /ZIF-67 composite was successfully fabricated by a facile method and used as adsorbent to remove direct blue 80 (DB80, azo dye) from water. Characterizations of Fe3 O4 /ZIF-67 composite were performed by scanning electron microscopy (SEM), powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), N2 adsorption/desorption isotherms, Fourier transform infrared spectroscopy (FTIR), and magnetic property analysis. As an adsorbent, the factors (such as adsorbent dose, pH, initial concentration, contact time, and temperature) affecting the adsorption performance of adsorbent were investigated. The optimal adsorption condition is 5 mg of Fe3 O4 /ZIF-67 composite in 8 ml of DB80 solution (70 mg/L) for 60 min at 318 K, and the pH value has little effect on the adsorption performance. The adsorption isotherm, kinetics, and thermodynamics of DB80 adsorbed on the Fe3 O4 /ZIF-67 composite were also studied. The experimental results revealed that the experimental data followed the Langmuir model and the adsorption behavior could be well explained by pseudo-second-order kinetic model. Thermodynamic analysis indicated that the adsorption was a spontaneous and endothermic process. Furthermore, the mechanism of DB80 adsorbed on the Fe3 O4 /ZIF-67 composite was proposed. The occurrence of adsorption might be caused by the π-π stacking interaction between Fe3 O4 /ZIF-67 composite and DB80. PRACTITIONER POINTS: Fe3 O4 /ZIF-67 composite was successfully fabricated via a facile method. Fe3 O4 /ZIF-67 composite was used to the adsorptive removal of direct blue 80 (azo dye). The kinetic characteristics and thermodynamic parameters were analyzed. The adsorption behavior might be ascribed to the π-π stacking interaction between Fe3 O4 /ZIF-67 composite and DB80.

Abstract
b-AP15 is a deubiquitinase (DUB) inhibitor of 19S proteasomes, which in turn targets ubiquitin C-terminal hydrolase 5 (UCHL5) and ubiquitin-specific peptidase 14 (USP14). Nuclear factor kappa B (NF-κB) is closely linked to cellular response in macrophages when the organism is in the state of microbial infection, and it acts as a vital part in the mechanism of inflammatory reaction. However, the molecular mechanism by which DUB inhibitors, especially b-AP15, regulates inflammation remains poorly understood. This study aimed to investigate the relationship between b-AP15 and inflammation. The results showed that b-AP15 treatment significantly reduced the amounts of inflammatory indicators, such as tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) in lipopolysaccharide (LPS)-stimulated THP-1 and macrophages. Meanwhile, similar results were obtained from in vivo experiments. In addition, b-AP15 also significantly improved the survival rate of sepsis mouse via high-density LPS mediation. Furthermore, b-AP15 also inhibited the ERK1/2 and JNK phosphorylation, increased IκBα levels, and inhibited NF-κB p65 by removing them from the cytoplasm into the nucleus. All these findings suggested that b-AP15 has anti-inflammatory action and acts as a potential neoteric target drug for treating microbial infection.

Abstract
Background Huangci Granule is a traditional Chinese medicine for treating metastatic colorectal cancer (mCRC). Objective To evaluate the efficacy and safety of Huangci Granule combination with chemotherapy and cetuximab (CET) or bevacizumab (BV) for treating mCRC. Methods We performed a randomized, controlled, and double-blind trial and recruited patients with mCRC who were planned to undergo chemotherapy combined with CET or BV. The treatment group was treated with Huangci Granule, while the control group was treated with placebo. Continuous treatment until disease progression, death, intolerable toxicity or up to 6 months. The primary endpoint was progression-free survival (PFS), and the secondary endpoint was quality of life and safety. Result 320 patients were randomly assigned to receive treatment, including 200 first-line patients and 120 second-line patients. In the first-line treatment, the median PFS was 9.59 months (95% CI, 6.94–13.25) vs 6.89 months (95% CI, 4.99–9.52) in treatment group and control group (HR, 0.69; 95% CI, 0.50–0.97; P = 0.027). Chinese medicine was an independent factor affecting the PFS. In the second-line treatment, the median PFS was 6.51 months (95% CI, 4.49–9.44) vs 4.53 months (95% CI, 3.12–6.57) in the treatment group and control group (HR, 0.65; 95% CI, 0.45–0.95; P = 0.020). Compared with the control group, “role function,” “social function,” “fatigue,” and “appetite loss” were significantly improved in the treatment (P < 0.05) and drug related grades 3 to 4 adverse events were less. Conclusion Huangci Granule combined with chemotherapy and CET or BV can prolong the PFS of mCRC, improve the quality of life, reduce adverse reactions, and have good safety.

Abstract
Objective: To determine the status of bone metastasis (BM) and prognosis factors of patients with renal cell carcinoma (RCC) in our center. Methods: The clinical and medical records of RCC patients with BM, who were admitted to the Department of Urology, Bone Oncology and Spine Surgery, Beijing Jishuitan Hospital from August 2009 to August 2017 were collected. The gender, age, time of BM, location of BM, numbers of BM, presence or absence of visceral metastasis, pathological types of BM were investigated. The patients were followed up regularly, and the survival curves were analyzed by Kaplan-Meier method. Cox proportional hazard regression model was used to estimate the prognostic factors. Results: A total of 51 RCC patients with bone metastasis were collected. The age of patients ranged from 38 to 76 (58.6±8.2) years old, including 39 males (76.5%) and 12 females (23.5%). The ratio of male to female was 3.25∶1. The patients were followed up for 8 to 109 months, with a median follow-up time of 30 months. The follow-up rate was 90.2%. Thirty-one (60.8%) patients died at the last follow-up, with a median overall survival (OS) time of 25 months. The median OS was 38 months and 20 months in the solitary BM group (26 cases, 51.0%) and BM ≥ 2 group (25 cases, 49.0%), respectively. The difference between the two groups was statistically significant (P=0.021). The median OS was 30 months, 69 months and 17 months in the axis BM group (22 cases, 43.1%), appendicular BM group (19 cases, 37.3%) and both the axis and appendicular BM group (10 cases, 19.6%), respectively. The difference between the groups was statistically significant (P=0.012). The median OS was 22 months and 38 months in the patients with (15 cases, 29.4%) and without (36 cases, 70.6%) visceral metastases groups, respectively. The difference between the two groups was statistically significant (P=0.007). Univariate and multivariate Cox regression analysis showed that the numbers of BM (HR=3.130, 95%CI: 1.502-6.520, P=0.035) and visceral metastasis (HR=4.699, 95%CI: 1.810-9.545, P=0.001) were independent prognostic factors for RCC with BM. Conclusions: Solitary BM, no visceral metastasis are good prognostic factors for RCC with BM. For these patients, radical resection of BM is feasible to improve survival rate.

Abstract
The objective of the paper is to explore the examination value of high-frequency ultrasonography in the postoperative rehabilitation treatment of Achilles tendon injury occurred during sports events. The high-frequency ultrasound imaging technique was applied to examine the Achilles
tendon injuries of patients. After the patients accepted Achilles tendon rupture repair surgeries, ultrasound imaging was applied to detect the rehabilitation conditions during the recovery processes. The diagnosis was mainly performed through the Achilles tendon sonograms examined 4 weeks,
6 weeks, 12 weeks, 24 weeks after the surgeries respectively; in addition, the changes in the American Orthopedic Foot and Ankle Score (AOFAS) and the elasticity modulus of repaired Achilles tendons were observed 8 weeks, 12 weeks, 24 weeks, and 48 weeks after the surgeries respectively. The
results showed that the Achilles tendon was significantly improved after the postoperative rehabilitation, and the average AOFAS score was positively correlated with the elasticity modulus of the repaired Achilles tendon. In addition, the research results also indicated that the high-frequency
ultrasound technology could accurately observe the thickness, area, and internal echo of the Achilles tendons of patients dynamically in real-time, which was convenient and quick. After the patient had undergone rehabilitation training, high-frequency ultrasound could be used to detect the
postoperative rehabilitation conditions of patients, thereby the real-time rehabilitation conditions of the patients would be obtained.

Abstract
Culex quinquefasciatus is a vector of many diseases that adversely impact human and animal health; however, compared to other mosquito vectors limited genome engineering technologies have been characterized for this vector. Clustered regularly interspaced short palindrome repeats-associated protein 9 (CRISPR-Cas9) based technologies are a powerful tool for genome engineering and functional genetics and consequently have transformed genetic studies in many organisms. Our objective was to improve upon the limited technologies available for genome editing in C. quinquefasciatus to create a reproducible and straightforward method for CRISPR-Cas9-targeted mutagenesis in this vector. Here we describe methods to achieve high embryo survival and mutagenesis rates and we provide details on the injection supplies and procedures, embryo handling and guide RNA (gRNA) target designs. Through these efforts, we achieved embryo survival rates and germline mutagenesis rates that greatly exceed previously reported rates in this vector. This work is also the first to characterize the white gene marker in this species, which is a valuable phenotypic marker for future transgenesis or mutagenesis of this vector. Overall, these tools provide the framework for future functional genetic studies in this important disease vector and may support the development of future gene drive and genetic technologies that can be used to control this vector.

Abstract
Rationale: Hyperlipidemia is a major risk factor of atherosclerosis and cardiovascular diseases (CVD). As a standard-of-care approach for hyperlipidemia, statins only reduce the risk of coronary artery disease by 20-40%, underscoring the importance of identifying molecular pathways for the design of drugs against this disorder. Alterations in microRNA (miRNA) expression have been reported in patients with hyperlipidemia and CVD. This study was designed to determine the mechanism of dysregulated miR-378a-3p under the status of hyperlipidemia and evaluate how miR-378a-3p regulates hepatic secretion of VLDL. Methods: Wild-type mice kept on a high fat diet were injected with miR-378a-3p inhibitor or a mini-circle expression system containing miR-378a precursor to study loss and gain-of functions of miR-378a-3p. Mice were treated with Triton WR1339 and 35S-methionine/cysteine to determine the effect of miR-378a-3p on hepatic secretion of VLDL. Database mining, luciferase assay, and ChIP (chromatin immunoprecipitation) were used to study the mechanism of dysregulated miR-378a-3p biogenesis. Results: miR-378a-3p expression is significantly increased in livers of hyperlipidemic mice. Sort1 (sortilin 1) was identified as a direct target of miR-378a-3p. By inhibiting the function of sortilin 1 as a transmembrane trafficking receptor, miR-378a-3p stabilized ApoB100 and promoted ApoB100 secretion in vitro. Liver-specific expression of miR-378a-3p stabilized ApoB100 and facilitated hepatic secretion of VLDL, which subsequently increased levels of VLDL/LDL cholesterol as well as triglycerides. In contrast, antagonizing miR-378a-3p using its inhibitor increased hepatic expression of Sort1 and reduced hepatic export of VLDL with its consequent effects of serum lipid levels. Additional knockdown of up-regulated Sort1 in livers of mice offset the effects of miR-378a-3p inhibitor, suggesting that Sort1 was indispensable for miR-378a-3p to promote secretion of VLDL and thereby high levels of circulating VLDL/LDL cholesterol and triglycerides. Furthermore, oncogenic E2F1 (E2F transcription factor 1) was identified as a transcriptional activator of miR-378a-3p. E2f1 knockdown, through reducing miR-378a-3p, impaired secretion of VLDL and reduced levels of VLDL/LDL cholesterol and triglycerides. Conclusions: This study defines a novel pathway of E2F1-miR-378a-3p-SORT1-ApoB100 that controls levels of circulating VLDL/LDL cholesterol and triglycerides by modulating degradation and secretion of ApoB100, and suggests the use of miR-378a-3p as a potential therapeutic target for dyslipidemia.

Abstract
Background Targeting the immune checkpoint pathway has demonstrated antitumor cytotoxicity in treatment-refractory head and neck squamous cell carcinoma (HNSC). To understand the molecular mechanisms underpinning its antitumor response, we characterized the immune landscape of HNSC by their tumor and stromal compartments to identify novel immune molecular subgroups. Patients and methods A training cohort of 522 HNSC samples from the Cancer Genome Atlas profiled by RNA sequencing was analyzed. We separated gene expression patterns from tumor, stromal, and immune cell gene using a non-negative matrix factorization algorithm. We correlated the expression patterns with a set of immune-related gene signatures, potential immune biomarkers, and clinicopathological features. Six independent datasets containing 838 HNSC samples were used for validation. Results Approximately 40% of HNSCs in the cohort (211/522) were identified to show enriched inflammatory response, enhanced cytolytic activity, and active interferon-γ signaling (all, P < 0.001). We named this new molecular class of tumors the Immune Class. Then we found it contained two distinct microenvironment-based subtypes, characterized by markers of active or exhausted immune response. The Exhausted Immune Class was characterized by enrichment of activated stroma and anti-inflammatory M2 macrophage signatures, WNT/transforming growth factor-β signaling pathway activation and poor survival (all, P < 0.05). An enriched proinflammatory M1 macrophage signature, enhanced cytolytic activity, abundant tumor-infiltrating lymphocytes, high human papillomavirus (HPV) infection, and favorable prognosis were associated with Active Immune Class (all, P < 0.05). The robustness of these immune molecular subgroups was verified in the validation cohorts, and Active Immune Class showed potential response to programmed cell death-1 blockade (P = 0.01). Conclusions This study revealed a novel Immune Class in HNSC; two subclasses characterized by active or exhausted immune responses were also identified. These findings provide new insights into tailoring immunotherapeutic strategies for different HNSC subgroups.

High content screening identifies licoisoflavone A as a bioactive compound of Tongmaiyangxin Pills to restrain cardiomyocyte hypertrophy via activating Sirt3. Phytomedicine 2020; 68:153171. [PMID: 32018211 DOI: 10.1016/j.phymed.2020.153171] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND Cardiac hypertrophy is a prominent feature of heart remodeling, which may eventually lead to heart failure. Tongmaiyangxin (TMYX) pills are a clinically used botanical drug for treating multiple cardiovascular diseases including chronic heart failure. The aim of the current study was to identify the bioactive compounds in Tongmaiyangxin pills that attenuate cardiomyocytes hypertrophy, and to investigate the underlying mechanism of action. METHODS AND RESULTS The anti-hypertrophy effect of TMYX was validated in isoproterenol-induced cardiac hypertrophy model in C57BL/6 mice. After TMYX treatment for 2 weeks, the heart ejection fraction and fractional shortening of the mice model was increased by approximately 20% and 15%, respectively, (p < 0.05). Besides, TMYX dose-dependently reduced the cross section area of cardiomyocytes in the angiotensin-II induced hypertrophy H9c2 model (p < 0.01). Combining high content screening and liquid chromatography mass spectrometry, four compounds with anti-cardiac hypertrophy effects were identified from TMYX, which includes emodin, licoisoflavone A, licoricone and glyasperin A. Licoisoflavone A is one of the compounds with most significant protective effect and we continued to investigate the mechanism. Primary cultures of neonatal rat cardiomyocytes were treated with a hypertrophic agonist phenylephrine (PE) in the presence or absence of licoisoflavone A. After 48 h of treatment, cells were harvested and mitochondrial acetylation was analyzed by western blotting and Image analysis. Interestingly, the results suggested that the anti-hypertrophic effects of licoisoflavone A depend on the activation of the deacetylase Sirt3 (p < 0.01). Finally, we showed that licoisoflavone A-treatment was able to decrease relative ANF and BNP levels in the hypertrophic cardiac cells (p < 0.01), but not in cells co-treated with Sirt3 inhibitors (3-TYP) (p > 0.05). CONCLUSION TMYX exerts its anti-hypertrophy effect possibly through upregulating Sirt3 expression. Four compounds were identified from TMYX which may be responsible for the anti-hypertrophy effect. Among these compounds, licoisoflavone A was demonstrated to block the hypertrophic response of cardiomyocytes, which required its positive regulation on the expression of Sirt3. These results suggested that licoisoflavone A is a potential Sirt3 activator with therapeutic effect on cardiac hypertrophy.

Abstract
The circular economy pattern is the key to solve the contradiction between industrial development and resource protection. Based on the principle of the "3Rs" of the circular economy (reduction, reuse, and resource utilization), and combined with the characteristics of industrial and provincial circular economy development from the perspective of material flow analysis, this study constructs an evaluation index system of industrial circular economy in China's provinces. A combination of the global entropy and the coefficient of variation methods is used to calculate the comprehensive index of industrial circular economy development. Furthermore, this study analyzes the development of China's provincial industrial circular economy from the two dimensions of time and space. The results show that China's industrial circular economy developed rapidly during the Eleventh and Twelfth Five-Year Plan periods. Resource output, resource consumption, and resource reuse and waste disposal have improved over time, but the outlook for emissions of major pollutants is not optimistic. China's industrial circular economy has significant spatial correlation and obvious regional differences, since the development of the circular economy requires a large amount of capital input, and the capacity of capital input fundamentally depends on the regional economic situation. Therefore, the spatial agglomeration pattern of China's industrial circular economy is roughly the same as that of China's economic development. Eastern China has the fastest development, followed by the central and northeast regions, while the western region, especially the northwest, lags the other regions.

Abstract
OBJECTIVE Abnormal remodeling of subchondral bone (SB) induced by estrogen deficiency has been shown to be involved in osteoarthritis (OA). Raloxifene (RAL) is commonly used to treat postmenopausal osteoporosis (OP). However, little is known about its effects on OA combined with estrogen deficiency. This study was performed to evaluate the efficacy of RAL on patella baja-induced patellofemoral joint OA (PFJOA) in an ovariectomized rat model. DESIGN Patellar ligament shortening (PLS) and ovariectomy (OVX) were performed simultaneously in 3-month-old female Sprague-Dawley rats, which were treated with RAL (10 mg/kg/day) or vehicle at 72 h postoperatively for 10 weeks. PFJOA was assessed by immunohistochemistry (IHC), real-time polymerase chain reaction (PCR), tartrate-resistant acid phosphatase (TRAP) staining, enzyme-linked immunosorbent assay (ELISA), micro-computed tomography (μCT), histomorphology and behavioral analyses. RESULTS X-ray examinations showed that patella baja was successfully established by PLS. Histomorphological analysis revealed that PFJOA was significantly exacerbated by OVX and markedly alleviated by RAL. Moreover, RAL improved cartilage metabolism by decreasing MMP-13, ADAMTS-4, and caspase-3 and increasing Col-II and aggrecan at both the protein and mRNA levels. Furthermore, RAL markedly improved bone mass and SB microarchitecture and reduced osteoclast numbers and the serum osteocalcin and CTX-I levels. Although RAL showed a trend toward reducing pain sensitivity based on mechanical allodynia testing, this result was not statistically significant. CONCLUSION These findings demonstrate that RAL treatment retards PFJOA progression in an ovariectomized rat model, suggesting that it may be a potential candidate for amelioration of the progression of PFJOA accompanied by postmenopausal OP.

Abstract
Objective: To analyze the improvement of clinical symptoms and recovery of neurological function in adult Japanese encephalitis, and study the prognostic factors. Methods: Follow-up was conducted for 112 hospitalized patients with Japanese encephalitis (JE) in adults at the Department of Neurology of three hospitals in Gansu province from July to October 2016, from July to October 2017, 6 months and 1 year after onset, respectively. The neurological functional recovery was evaluated by modified Ranking Scale (mRS).The influencing factors were analyzed by logistic regression model. Results: Among the 112 adult patients with JE after 1year follow-up, 57% (64/112) were completely recovered (mRS score=0), and 14%(16/112) had mild neurological dysfunction (mRS score=1 or 2 points), 20% (22/112) had moderate to severe neurological dysfunction (mRS score 3 to 5), and 9% (10/112) died. In 102 survivors, decreased consciousness were fully recovered (100%), 75% of the mental and behavior disorders, 64% of cognitive/memory impairment, 71% of language function disorder, 61% of paralysis, 73% of extrapyramidal symptoms were fully recovered, and 92% of the seizures were controlled. Comparison of clinical data of initial on-set between good prognosis group (mRS score≤2, 80 cases) and poor prognosis group (mRS score>2, 32 cases) showed that initial clinical manifestation with seizures, consciousness (GCS score), cerebrospinal fluid pressure, and lesion of MRI involved in midbrain had statistically significant differences (all P<0.05) . Multivariate analysis demonstrated that cerebrospinal fluid (CSF) pressure>250 mmH(2)O and lesion of midbrain in MRI were independent risk factors of poor prognosis in adult patients with JE. Conclusion: JE is an acute and infectious viral encephalitis of the central nervous system with high disability and mortality. Most patients were completely recovered, and some had neurological sequelae. CSF pressure>250 mmH(2)O and lesion of midbrain in MRI are independent risk factors for poor prognosis.

Abstract
Tumor angiogenesis is an important factor which precipitates recurrence and metastasis of colorectal cancer (CRC). Angiogenesis is also a significant feature which accompanies invasion and metastasis of CRC. Tumor hypoxia activates hypoxia inducible factor (HIF), which promotes angiogenesis in CRC. HIF significantly promotes cell proliferation and angiogenesis in CRC, facilitating invasion and metastasis. Tanshinone IIA (Tan IIA) has been revealed to effectively inhibit angiogenesis in CRC, although the underlying mechanism remains to be determined. The aim of the present study was to determine the effects of HIF-1α on hypoxia induced angiogenesis in CRC cells, the effects of Tan IIA on the expression of pro-angiogenic factors in CRC cells, and on human umbilical vein endothelial cell (HUVEC) tube formation in normal and hypoxic conditions. The results of the present study revealed that Tan IIA not only decreased HIF-1α expression and inhibited the secretion level of vascular endothelial growth factor and basic fibroblast growth factor, but also efficiently decreased proliferation, tube formation and metastasis of HUVECs. The results highlight the potential of Tan IIA-mediated targeting of HIF-1α as a potential therapeutic option for treatment of patients with CRC.

Abstract
Objective: To examine the mortality rate and relative factors associate with ventricular septal rupture in myocardial infarction patients. Methods: A total of 51 patients who suffered from myocardial infarction complicating with ventricular septal rupture received operative procedures between January 2005 and December 2018 in Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University, were retrospectively analyzed. There were 34 males and 17 females, with an age of (63±8) years (range: 44 to 82 years). The time between ventricular septal rupture and surgical procedure was (44±39) days (range: 3 to 187 days). The t test and χ(2) test were used for univariate analysis, Logistics regression model was used for multivariate analysis of in-hospital mortality relative factors. Results: There were 8 patients dead in hospital, 43 patients survived, the overall mortality rate was 15.7% in hospital. The post-operation mortality rate was 2/3 of who suffered ventricular septal rupture and underwent operation within 1 week, but it's markedly decreased to 6.5% if the time over 4 weeks. Univariate analysis showed that renal failure before operation, creatinine before operation, left ventricular ejection fraction, cardiac function (New York Heart Association) grade Ⅳ, severe tricuspid regurgitation, dialysis post-operation, creatinine of the first day of post-operation, the time between and operation more than 4 weeks were in-hospital mortality relative factors. Multivariate analysis reflected that advanced age (OR=1.32, 95%CI: 1.05 to 1.75, P=0.033), cardiac function grade Ⅳ (OR=2.25, 95%CI: 1.62 to 2.82, P=0.003), severe tricuspid regurgitation (OR= 1.82, 95%CI: 1.31 to 2.43, P=0.001), renal failure before operation (OR=1.78, 95%CI: 1.26 to 2.32, P=0.015), the time between ventricular septal rupture and operation less than 1 week (OR=2.50, 95%CI: 1.52 to 2.98, P=0.012), were independent in-hospital mortality relative factors. Conclusions: The surgery operation is an effective way to deal with ventricular septal rupture combined with myocardial infarction. The independent relative factors of in-hospital mortality are advanced age, cardiac function grade Ⅳ, renal failure before operation, severe tricuspid regurgitation, the time between ventricular septal rupture and operation less than 1 week.

Abstract
Atherosclerosis is regarded as a chronic progressive inflammatory disease and is a basic pathophysiological process in coronary artery disease which is life threatening in clinic. The formation of foam cell plays a key role in the pathogenesis of atherosclerosis. OxLDL is a significant factor in progression of coronary artery disease. Our studies have demonstrated that USP14 promotes cancer development and mediates progression of cardiac hypertrophy and LPS‐induced inflammation. However, the underlying mechanism of USP14 is unknown. In this study, we found that the inhibition of USP14 significantly suppressed the oxLDL uptake, subsequently decreased the foam cell formation. Surprisingly, USP14 has an effect on the expression of CD36 but not SR‐A, ABCA1, Lox‐1, ABCG1 and SR‐Bl. Furthermore, USP14 stabilizes CD36 protein via cleaving the ubiquitin chain on CD36. Blocking CD36 activation using antibody‐dependent blocking assay remarkably attenuated the function of USP14 on the formation of foam cell. In summary, our results suggested that the inhibition of USP14 decreases foam cell formation by down‐regulating CD36‐mediated lipid uptake and provides a potential therapeutic target for atherosclerosis.

Abstract
Objective: To find more objective evidence and support for clinical classification of Parkinson's disease by means of tremor analysis in patients with early confirmed Parkinson's disease. Methods: A cross-sectional study was conducted to collect 65 patients with early Parkinson's disease treated in the Third Hospital of Peking University from January 2015 to December 2016. Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn-Yahr scale (H-Y scale), Mini-mental state examination (MMSE), Hamilton depression scale (HAMD) were recorded in all patients. According to the ratio of UPDRS rigidity score to tremor score, the patients were divided into tremor dominant (TD), postural instability/gait difficulty (PIGD) and mixed types. All patients were examined by tremor analysis and the results were analyzed and compared. Results: Among the 65 patients, the mean age of onset was (63±10) years, the course of disease was (14±8) months. Twenty-one patients were classified to TD group, 28 patients were classified to PIGD type, and 16 patients with mixed type. There was no significant difference in frequency and amplitude of tremor between the three groups (P>0.05), but the proportion of alternating contraction and harmonic resonance of active and antagonistic muscles in TD group was significantly higher (P<0.05). Twenty patients (71.4%) in TD group showed typical Parkinson's disease manifestations in tremor analysis. Only four patients (14.3%) in PIGD group showed the typical manifestations. More patients in PIGD group showed no clear main peak of tremor at rest. Some patients showed 6-8 Hz/sec peak frequency in posture position and simultaneous contraction of the active and antagonist muscles. These two manifestations occured simultaneously in mixed type patients, including 10 cases (62.5%) with typical Parkinson's disease manifestations. Conclusion: As an objective electrophysiological method to evaluate tremor type, tremor analysis can be used as an important assistant method for clinical classification of Parkinson's disease. It can provide information of the pathway of pathological loss in different types and give important hints in prognosis and treatment.

Abstract
Intrigued by the discovery of high-temperature superconductivity in a single unit-cell layer of FeSe film on SrTiO_{3}, researchers recently found large superconductinglike energy gaps in K-adsorbed multilayer FeSe films by angle-resolved photoemission and scanning tunneling spectroscopy. However, the existence and nature of the high-temperature superconductivity inferred by the spectroscopic studies has not been investigated by measurements of zero resistance or the Meissner effect due to the fragility of K atoms in air. Using a self-developed multifunctional scanning tunneling microscope, we succeed in observing the diamagnetic response of K-adsorbed multilayer FeSe films, and thus find a dome-shaped relation between the critical temperature (T_{c}) and K coverage. Intriguingly, T_{c} exhibits an approximately linear dependence on the superfluid density in the whole K adsorbed region. Moreover, the quadratic low-temperature variation in the London penetration depth indicates a sign-reversal order parameter. These results provide compelling information towards further understanding of the high-temperature superconductivity in FeSe-derived superconductors.

Abstract
Objective: To investigate the sleep quality of prison policemen and explore its influencing factors, so as to provide reference for improving the sleep quality of prison policemen. Methods: In August 2013, 177 policemen in a prison were selected by cluster sampling. The sleep quality of 177 prison policemen was investigated by Pittsburgh Sleep Quality Index Scale and General Situation Questionnaire, and the influencing factors were analyzed. Results: The PSQI scores of 177 prison policemen were (7.47+3.80). There were significant differences between the PSQI scores of prison policemen and the normal adult norm (P<0.05). According to the standard of poor sleep quality, 84 prison policemen (47.46%) had poor sleep quality, and the prison policemen scored higher on daytime dysfunction, subjective sleep quality, sleeping time and sleeping time components. Single factor t test and single factor variance analysis showed that there were significant differences in sleep quality among prison policemen in gender, age, educational level and job classification (P <0.05). The results of multiple stepwise regression analysis showed that gender, age and job classification entered the regression equation with PSQI total score as dependent variable (β=0.167, 0.270, 0.222) . Conclusion: The sleep quality of prison policemen is worse than that of normal adults, and is affected by gender, age, job classification and other factors, which should be paid attention to by prison administrators.

Abstract
OBJECTIVE To explore the association between miR-1298 expression and clinicopathological factors, prognosis of gastric cancer (GC) patients and biological functions underlying the GC progression. PATIENTS AND METHODS Expression of miR-1298 was examined by qRT-PCR in GC tissues and cells, the adjacent normal tissues and normal gastric cell line GES-1 cells were used as controls. Association of disease-free survival (DFS) and overall survival (OS) time with miR-1298 expression was analyzed by Kaplan-Meier analysis and log-rank test. Univariate and multivariate analysis were also performed to analyze relative prognostic risk factors of GC patients. Cell proliferation and invasion assays were used to examine cell proliferation and invasion capacities in vitro. The relative protein expression was analyzed by Western blot analysis. RESULTS MiR-1298 expression was lower in GC tissues and cells, compared to adjacent normal tissues and GES-1 cells, respectively. Lower miR-1298 expression levels were associated with lymph node metastasis and TNM stage. Kaplan-Meier analysis showed that lower miR-1298 expression predicted poor DFS and OS of GC patients. Furthermore, we demonstrated that lymph node metastasis, TNM stage, and lower miR-1298 expression were independent risk factors for DFS and OS in GC patients. In vitro, miR-1298 overexpression inhibited cell proliferation and invasion abilities. Additionally, our results revealed that miR-1298 overexpression suppressed PI3K/AKT signaling pathway in GC cells. CONCLUSIONS Our evidence indicated that miR-1298 may provide a specifically promising target for therapy of GC patients.
