Abstract
OBJECTIVE The purpose of this study was to evaluate the inclination and determinants influencing the selection of hospice care service institutions among elderly individuals in China. DESIGN The study conducted has a cross-sectional design. SETTING The study was conducted at four urban community centres in Wuhu, Anhui Province, China. PARTICIPANTS The sample consisted of 642 older adults, with ages ranging from 60 to over (mean age=71.03 years, SD=7.18). METHOD This study, based on the Anderson model, developed a questionnaire after conducting a preliminary survey and engaging in several group discussions. The final questionnaire encompassed the basic information, health status, attitude towards hospice care, choice of hospice care institutions and reasons of the older people. A regional population study was conducted using the Logistic regression model to estimate the ORs (OR) of influencing factors selected by hospice services. RESULTS 38.5% of respondents expressed their willingness to receive hospice care, while 22.3% were unwilling and 39.3% felt ambivalent towards it. The acceptance rate of older people in hospice care increases with higher levels of education and monthly income. 47.0% of older people opted for hospice care in a general hospital ward, indicating that demand for hospice services among older people in Wuhu City is primarily focused on such wards. The univariate analysis revealed significant differences in the willingness of older individuals to accept hospice care services based on gender, age, educational attainment and income levels. Regardless of the location of hospice care, older men had a lower likelihood of being willing to use hospice services compared with older women. The proportion of older women choosing a hospice ward or general hospital was 53.8%, which was higher than that of older men at 42.0%. The proportion of older men choosing a community health service institution was 31.6%, higher than 23.3% of women. The educational level differences significantly influence the older people's inclination towards receiving hospice care. CONCLUSION With the ageing population of Wuhu City on the rise, there is an increasing demand for hospice services. In their final journey, older individuals require multilevel hospice care services, which necessitates equipping general hospitals with hospice wards and using community health service centres to meet their specific needs.

Abstract
AIMS To analyse spatial and temporal changes in the global burden of diabetes mellitus (DM) attributable to dietary factors from 1990 to 2019. MATERIALS AND METHODS The burden of DM was analysed in terms of age-standardized disability-adjusted life-year (DALY) rates and age-standardized death rates (ASDRs), which were obtained from the Global Burden of Disease Study 2019, and their corresponding estimated annual percentage changes (EAPCs). RESULTS The ASDR exhibited a decreasing trend (EAPC = -0.02), while the age-standardized DALY rate exhibited an increasing trend (EAPC = 0.65). Forty-four percent of the burden of DM was attributable to dietary factors, with the three largest contributors being high intake of red meat, high intake of processed meat, and low intake of fruit. Residence in a region with a high sociodemographic index (SDI) was associated with a diet low in whole grains and high in red meat and processed meat, while residence in a low-SDI region was associated with a diet low in whole grains and fruits, and high in red meat. CONCLUSIONS The age-standardized DALYs of DM attributable to dietary factors increased between 1990 and 2019 but differed among areas. The three largest dietary contributors to the burden of DM were high intake of red meat, high intake of processed meat, and low intake of fruit.

Abstract
BACKGROUND AND AIMS Parathyroid hormone receptor-1 (PTH1R) is a class B G protein-coupled receptor central to skeletal development, bone turnover, and calcium homeostasis. However, the role of PTH1R signaling in liver fibrosis is largely unknown. Here, the role of PTH1R signaling in the activation of HSCs and hepatic fibrosis was examined. APPROACH AND RESULTS PTH1R was highly expressed in activated HSCs and fibrotic liver by using human liver specimens or carbon tetrachloride (CCl 4 )-treated or methionine and choline-deficient diet (MCD)-fed C57/BL6 mice. The mRNA level of hepatic PTH1R was positively correlated to α-smooth muscle actin in patients with liver cirrhosis. Mice with HSCs-specific PTH1R deletion were protected from CCl 4 , MCD, or western diet, plus low-dose CCl 4 -induced liver fibrosis. Conversely, parathyroid hormone (PTH) aggravated liver fibrosis in CCl 4 -treated mice. Mouse primary HSCs and LX2 cell lines were used for in vitro experiments. Molecular analyses by luciferase reporter assays and chromatin immunoprecipitation assays in combination with mRNA sequencing in HSCs revealed that cAMP response element-binding protein-like 2 (Crebl2), a novel regulator in HSCs treated by PTH that interacted with mothers against decapentaplegic homolog 3 (SMAD3) and increased the transcription of TGFβ in activating HSCs and collagen deposition. In agreement, HSCs-specific Crebl2 deletion ameliorated PTH-induced liver fibrosis in CCl 4 -treated mice. CONCLUSIONS In both mouse and human models, we found that PTH1R was highly expressed in activated HSCs and fibrotic liver. PTH1R signaling regulated collagen production in the HSCs through Crebl2/SMAD3/TGFβ regulatory circuits. Blockade of PTH1R signaling in HSCs might help mitigate the development of liver fibrosis.

Abstract
Oocystis borgei, a microalgae species employed for regulating the quality of aquaculture water, demonstrates the capacity to adsorb noxious substances, curtail the growth of detrimental bacteria, and outcompete blooming cyanobacteria. It can be concentrated by natural sedimentation and stored at room temperature, making it costless and simple to transport and use. To study the mechanism of adaptation to room temperature preservation, O. borgei was concentrated (1.19 × 107-1.21 × 107 cell/mL) and stored for 50 days at low (5 °C, LT), normal (25 °C, NT), and high (35 °C, HT) temperatures, respectively. Polysaccharide content, lipid content, cell survival, and resuscitation were evaluated. RNA-Seq was also used to examine how concentrated O. borgei responded to temperature. During storage, there was an increase in polysaccharide content and a decrease in lipid content, with both being significantly upregulated in the LT and HT groups. Survival and cell density were highest in the NT group. The RNA-Seq analysis revealed extensive differences in transcript levels. ATP synthesis was inhibited in the LT group due to the reduced expression of PsaD, PsaE, PsaF, PsaK, and PsaL. Under HT, the formation of reactive oxygen species (ROS) was facilitated by low levels of redox-related genes (nirA) and high levels of oxidative genes (gdhA, glna, and glts). The findings suggest that storing concentrated O. borgei at room temperature is optimal for microalgae preservation, enhancing theoretical research in this field. Our study provides further theoretical and practical support for the development of O. borgei as a live ecological preparation for aquaculture microalgae ecology management.

Abstract
Curcumin is a polyphenol extracted from the rhizome of turmeric, and our previous research showed that curcumin inhibited cholesterol absorption and had cholesterol-lowering effect. Bisphenol A (BPA), a common plasticizer, is widely used in the manufacture of food packaging and is associated with non-alcoholic fatty liver disease (NAFLD). We hypothesized that curcumin could protect against BPA-induced hepatic steatosis by inhibiting cholesterol absorption and synthesis. Male CD-1 mice fed BPA-contaminated diet with or without curcumin for 24 weeks were used to test our hypothesis. We found that chronic low-dose BPA exposure significantly increased the levels of serum triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol and the contents of liver TG and TC, resulting in liver fat accumulation and hepatic steatosis while curcumin supplementation could alleviate BPA-induced dyslipidemia and hepatic steatosis. Moreover, the anti-steatosis and cholesterol-lowering effects of curcumin against BPA coincided with a significant reduction in intestinal cholesterol absorption and liver cholesterol synthesis, which was modulated by suppressing the expression of sterol regulatory element-binding protein-2 (SREBP-2), Niemann-Pick C1-like 1 (NPC1L1), and 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) in the small intestine and liver. In addition, the expression levels of liver lipogenic genes such as liver X receptor alpha (LXRα), SREBP-1c, acetyl-CoA carboxylase 1 (ACC1), and ACC2 were also markedly down-regulated by curcumin. Overall, our findings indicated that curcumin inhibited BPA-induced intestinal cholesterol absorption and liver cholesterol synthesis by suppressing SREBP-2, NPC1L1, and HMGCR expression, subsequently reducing liver cholesterol accumulation and fat synthesis, thereby preventing hepatic steatosis and NAFLD.

Abstract
Di-(2-ethylhexyl) phthalate (DEHP) is the most commonly used plasticizer and is ubiquitous in the environment and food. As a result, diet is the most significant source of exposure to DEHP in the general population. However, there is little research about the impact of DEHP on the risk of nonalcoholic fatty liver disease (NAFLD) or significant fibrosis in human beings. A cross-sectional analysis was performed using the National Health and Nutrition Examination Survey (NHANES) 2017-2018 data. Controlled attenuation parameter (CAP) and median liver stiffness measurement (LSM) were acquired by vibration-controlled transient elastography for diagnosis of NAFLD and significant fibrosis. The concentration of DEHP (∑DEHP) was calculated by each metabolite and split into quartiles for analysis. Results of logistic regression models showed that the risk of NAFLD was increased in those with higher concentration of urinary DEHP [ΣDEHP (OR = 1.22, 95%CI = 1.09-1.36)]. However, no significant association was found between urinary DEHP and significant fibrosis in the fully adjusted model. Mediation analyses suggested that the total effect of urinary DEHP on NAFLD risk mediated by BMI was 46.28% and by WC was 65.89%.

Abstract
Umbilical cord-mesenchymal stem cells (UC-MSCs)-derived exosomes have been considered as an effective treatment for ischemic stroke. CircRNA BBS2 (circBBS2) was demonstrated to be down-regulated in patients with ischemic stroke. However, the role of UC-MSCs-derived exosomal circBBS2 in ischemic stroke and potential mechanisms remain unclear. Hypoxia/reperfusion (H/R)-exposed SH-SY5Y cells and middle cerebral artery occlusion (MCAO)-treated rats were served as in vitro and in vivo models of ischemic stroke. Target gene expression was detected by qRT-PCR. Cell viability was assessed by MTT assay. Ferroptosis was determined by iron, MDA, GSH, and lipid ROS levels. Protein levels were measured by Western blotting. The target relationships among circBBS2, miR-494, and SLC7A11 were validated by RNA-pull down, RIP, and dual-luciferase reporter assays. TTC and HE staining were performed to evaluate cerebral infarction volume and neuropathological changes. circBBS2 was lowly expressed and ferroptosis was triggered in MCAO rats and H/R-stimulated SH-SY5Y cells. UC-MSCs-derived exosomes enhanced cell viability and restrained ferroptosis via increasing circBBS2 expression in SH-SY5Y cells. Mechanistically, circBBS2 sponged miR-494 to enhance the SLC7A11 level. Knockdown of miR-494 or SLC7A11 reversed the effects of silencing circBBS2 or miR-494 on ferroptosis of SH-SY5Y cells, respectively. Furthermore, UC-MSCs-derived exosomes attenuated ischemic stroke in rats via delivering circBBS2 to inhibit ferroptosis. UC-MSCs-derived exosomal circBBS2 enhanced SLC7A11 expression via sponging miR-494, therefore repressing ferroptosis and relieving ischemic stroke. Our findings shed light on a novel mechanism for UC-MSCs-derived exosomes in the treatment of ischemic stroke.

Abstract
Uncontrolled inflammation storm induced by sepsis may lead to severe organ dysfunction and secondary immunosuppression, which is one of the main reasons for high mortality and prolonged hospitalization of septic patients. However, there is a lack of effective treatments for it at present. Here, we report an efferocytosis-inspired nanodrug (BCN@M) to treat sepsis and secondary immunosuppression via regulating the macrophage function. Bioactive molecular curcumin was loaded with bovine serum albumin and then coated with the damaged erythrocyte membrane derived from septic mice. It was found that the septic erythrocytes promoted the efferocytosis signal and BCN@M uptake efficiency by macrophages. The well-constructed BCN@M nanodrug reduced the hyperinflammation in sepsis and restored the bacterial clearance ability of macrophage in the secondary immunosuppression state. This study highlights BCN@M as an efferocytosis-inspired nanodrug to alleviate hyperinflammation and secondary immunosuppression of sepsis.

Abstract
Candidiasis is an infection caused by fungi from a Candida species, most commonly Candida albicans. C. albicans is an opportunistic fungal pathogen typically residing on human skin and mucous membranes of the mouth, intestines or vagina. It can cause a wide variety of mucocutaneous barrier and systemic infections; and becomes a severe health problem in HIV/AIDS patients and in individuals who are immunocompromised following chemotherapy, treatment with immunosuppressive agents or after antibiotic-induced dysbiosis. However, the immune mechanism of host resistance to C. albicans infection is not fully understood, there are a limited number of therapeutic antifungal drugs for candidiasis, and these have disadvantages that limit their clinical application. Therefore, it is urgent to uncover the immune mechanisms of the host protecting against candidiasis and to develop new antifungal strategies. This review synthesizes current knowledge of host immune defense mechanisms from cutaneous candidiasis to invasive C. albicans infection and documents promising insights for treating candidiasis through inhibitors of potential antifungal target proteins.

Abstract
Chlamydomonas reinhardtii is a unicellular green alga that can grow heterotrophically by using acetate as a carbon source. Carotenoids are natural pigments with biological activity and color, which have functions such as antioxidant, anti-inflammatory, vision protection, etc., and have high commercial value and prospects. We transformed Chlamydomonas reinhardtii with the BKT genes from Phaffia rhodozyma (PrBKT) and Chlamydomonas reinhardtii (CrBKT) via plasmid vector, and screened out the stable transformed algal strains C18 and P1. Under the condition that the cell density of growth was not affected, the total carotenoid content of C18 and P1 was 2.13-fold and 2.20-fold higher than that of the WT, respectively. CrBKT increased the levels of β-carotene and astaxanthin by 1.84-fold and 1.21-fold, respectively, while PrBKT increased them by 1.11-fold and 1.27-fold, respectively. Transcriptome and metabolome analysis of C18 and P1 showed that the overexpression of CrBKT only up-regulated the transcription level of BKT and LCYE (the gene of lycopene e-cyclase). However, in P1, overexpression of PrBKT also led to the up-regulation of ZDS (the gene of ζ-carotene desaturase) and CHYB (the gene of β-carotene hydroxylase). Metabolome results showed that the relative content of canthaxanthin, an intermediate metabolite of astaxanthin synthesis in C18 and P1, decreased. The overall results indicate that there is a structural difference between CrBKT and PrBKT, and overexpression of PrBKT in Chlamydomonas reinhardtii seems to cause more genes in carotenoid pathway metabolism to be up-regulated.

Abstract
Niemann-pick C1-like 1 (NPC1L1) mediates cholesterol absorption and plays a key role in the pathogenesis of non-alcoholic simple fatty liver (NASFL). Our previous study showed that curcumin reduced NPC1L1 expression and cholesterol absorption in Caco-2 cells. This study aimed to investigate whether curcumin could inhibit intestinal and hepatic NPC1L1 expression through suppressing sterol regulatory element binding protein-2 (SREBP-2) / hepatocyte nuclear factor 1α (HNF1α) pathway, then exert anti-NASFL effects. Six-week hamsters were fed high-fat diet (HFD) with or without 0.1% curcumin for 12 weeks. Curcumin supplementation lowered blood total cholesterol (TC), triglycerides (TG) and low density lipoprotein cholesterol levels (20.2%, 48.7% and 36.5%), and reduced liver TC and TG contents (26.1% and 26.5%). Oil Red O staining demonstrated that curcumin significantly alleviated HFD-induced liver fat accumulation and hepatic steatosis, which was accompanied by reduced intestinal and hepatic NPC1L1, SREBP-2 and HNF1α expression (p < 0.05) and increased fecal neutral sterol excretion (114.5%). Furthermore, curcumin decreased cholesterol absorption in Caco-2 cells and HepG2 cells (49.2 % and 52.7 %). The inhibitory effects of curcumin on NPC1L1 expression and cholesterol absorption could be prevented by blockade of the SREBP-2 and HNF1α pathway. These findings indicated that curcumin protected against HFD-induced NASFL by inhibiting intestinal and hepatic NPC1L1 expression via down-regulation of SREBP-2/HNF1α pathway, thus reducing intestinal cholesterol absorption and hepatic biliary cholesterol reabsorption, consequently alleviating liver cholesterol accumulation and steatosis. Our study provides evidence for curcumin as a potential nutritional therapy for NASFL by regulating NPC1L1 and enterohepatic circulation of cholesterol.

Abstract
Dysregulation of gut microbiota-mediated bile acid (BA) metabolism plays an important role in the pathogenesis of hepatic steatosis and nonalcoholic fatty liver disease (NAFLD). Our previous studies found that bisphenol A (BPA) exposure induced hepatic steatosis and gut microbiota dysbiosis. However, whether the gut microbiota-dependent BA metabolism alterations were involved in BPA-induced hepatic steatosis remains unclear. Therefore, we explored the gut microbiota-related metabolic mechanisms of hepatic steatosis induced by BPA. Male CD-1 mice were exposed to low-dose BPA (50 μg/kg/day) for 6 months. Fecal microbiota transplantation (FMT) and broad-spectrum antibiotic cocktail (ABX) treatment were further adopted to test the role of gut microbiota in the adverse effects of BPA. We found that BPA induced hepatic steatosis in mice. Additionally, 16S rRNA gene sequencing showed that BPA reduced the relative abundance of Bacteroides, Parabacteroides and Akkermansia, which are associated with BA metabolism. Metabolomic analyses demonstrated that BPA significantly altered the ratio of conjugated to unconjugated BAs and increased the total level of taurine-α/β-muricholic acid while decreasing the level of chenodeoxycholic acid, thus inhibiting the activation of special receptors, including farnesoid X receptor (FXR) and Takeda G protein-coupled receptor 5 (TGR5), in the ileum and liver. The inhibition of FXR reduced short heterodimer partner and subsequently induced cholesterol 7α-hydroxylase and sterol regulatory element-binding protein-1c expression, which is related to hepatic BA synthesis and lipogenesis, eventually leading to liver cholestasis and steatosis. Furthermore, we found that mice that received FMT from BPA-exposed mice developed hepatic steatosis, and the influences of BPA on hepatic steatosis and FXR/TGR5 signaling could be eliminated by ABX treatment, confirming the role of gut microbiota in BPA effects. Collectively, our study illustrates that suppressed microbiota-BA-FXR/TGR signaling pathways may be a potential mechanism for hepatic steatosis induced by BPA, providing a new target for the prevention of BPA-induced NAFLD.

Abstract
Objective: To examine the efficacy and safety of laparoscopic surgery for gallbladder carcinoma. Methods: The data of 197 gallbladder carcinoma patients admitted at Peking Union Medical College Hospital between January 2012 and September 2022 were analyzed retrospectively. There were 86 males and 111 females,with age of (64.4±9.8)years(range:35 to 89 years). Patients were divided into laparoscopic group(n=53) and open group(n=144) according to different surgical methods. The general information of the two groups were matched by propensity score matching,and the clinical data and prognosis were compared between the two groups. Categorical variables were analyzed using χ2 test or Fisher's exact test,as appropriate. Continuous variables with and without normal distribution were analyzed using t-test and Mann-Whitney U test,respectively. Kaplan-Meier curves with Log-rank test were used to analyze the cumulative survival rates. Results: Forty-eight pairs of patients were matched successfully. There was no difference in general information,cholecystolithiasis,partial hepatectomy,and tumor stage between two groups(all P>0.05). The laparoscopic group had shorter operation time(t=-3.987,P<0.01),less bleeding(Z=-4.862,P<0.01),shorter total(Z=-5.009,P<0.01) and postoperative(Z=-5.412,P<0.01) hospital stay. Seventeen patients had postoperative complications. According to the Clavien-Dindo system,there were 4,11,1,and 1 patient with grade Ⅰ,Ⅱ,Ⅲa,and Ⅲb,respectively. All complications were improved after active treatment. After a median follow-up of 24(36) months(range:3 to 130 months),56 patients(58.3%) survived without tumor,7 patients(7.3%) survived with tumor,and 33 patients(34.4%) died. According to the Kaplan-Meier curves,there was no significant difference between laparoscopic and open groups in disease free(χ2=0.399,P=0.528) and overall(χ2=0.672,P=0.412) survival rates. Conclusions: The laparoscopic surgery is safe and effective in selected patients with gallbladder carcinoma. It can reduce surgical trauma and enhance patient recovery without increasing complication. Its prognosis is similar to that of open surgery.

Abstract
CDK4/6 inhibitors have proven their potency for the treatment of cancer but only in combination with hormone or targeted therapies. The aim of this study was the identification of molecules that are involved in response mechanisms to CDK4/6 inhibitors and the development of novel combination therapies with corresponding inhibitors in bladder cancer. Genes of response to therapy and genes that confer resistance to the CDK4/6 inhibitor palbociclib were identified by performing an analysis of published literature and own published data using a CRISPR-dCas9 genome wide gain of function screen. Genes that were down-regulated upon treatment were compared with genes that confer resistance when up-regulated. Two of the top 5 genes were validated by quantitative PCR and western blotting upon treatment with palbociclib in the bladder cancer cell lines T24, RT112 and UMUC3. As inhibitors for combination therapy, we used ciprofloxacin, paprotrain, ispinesib and SR31527. Analysis of synergy was done using the "zero interaction potency" model. Cell growth was examined using sulforhodamine B staining. A list of genes that met the requirements for inclusion in the study was generated from 7 publications. Of the 5 most relevant genes, MCM6 and KIFC1 were chosen and their down-regulation upon treatment with palbociclib was confirmed by qPCR and immunoblotting. The combination of inhibitors against both, KIFC1 and MCM6 with PD resulted in a synergistic inhibition of cell growth. We have identified 2 molecular targets whose inhibition has promising potential for effective combination therapies with the CDK4/6 inhibitor palbociclib.

Abstract
Regulated cell death (RCD) contributes to reshaping the tumor immune microenvironment and participating in the progression of non-small cell lung cancer (NSCLC); however, related mechanisms have not been fully disclosed. Here, we identified 5 subclusters of NSCLC based on consensus clustering of 3429 RCD-associated genes in the TCGA database and depicted the genomic features and immune landscape of these clusters. Importantly, the clusters provided insights into recognizing tumor microenvironment (TME) and tumor responses to immunotherapy and chemotherapy. Further, we established and validated an RCD-Risk model based on RCD-associated genes, which strongly predicted the prognosis, TME, and immunotherapy outcomes in NSCLC patients. Notably, tissue microarray staining confirmed that the expression of LDLRAD3, a core gene in RCD-Risk model, correlated with poor survival. In conclusion, we developed a novel RCD classification system and RCD-Risk model of NSCLC, serving as a robust and promising predictor for prognosis and immunotherapy benefit of individual NSCLC patients.

Abstract
Acute myocardial infarction (AMI) is usually caused by coronary thrombosis. However, the short half-life, lack of targetability and inevitable ischemia/reperfusion injury secondary to revascularization, which characterizes tissue plasminogen activator (tPA) limit its thrombolytic efficacy for AMI. To address the targeted and site-specific delivery of tPA, the current study reports the construction of a thrombus-targeting and responsive biomimetic nanoparticle (PTPN) for spatiotemporal treatment of AMI. PTPN was constituted by the thrombus microenvironment- responsive phenylboronic acid (PBA) nanocarrier, antioxidant molecular protocatechualdehyde (PC) and tPA with thrombolytic effect, which were enclosed by the platelet membrane. The thrombus-targeting capability of the platelet membrane enabled the adhesion of PTPN to damaged endothelial cells. The nanoparticle disintegrated under slightly acid condition and re-opened the infarct-related artery during the period of ischemia. Sequentially, ROS induced by blood reperfusion was eliminated by PC released from particle disintegration, and the cardiomyocyte mitochondrial function was protected from reperfusion injury. Therefore, this thrombus-specific/responsive biomimetic nanomedicine provides a spatiotemporal paradigm for AMI treatment with promising clinical translation prospects.

Abstract
Currently, the whole world is facing hunger due to the increase in the global population and the rising level of food consumption. Unfortunately, the impact of environmental, climate, and political issues on agriculture has resulted in limited global food resources. Thus, it is important to develop new food sources that are environmentally friendly and not subject to climate or space limitations. Microalgae represent a potential source of nutrients and bioactive components for a wide range of high-value products. Advances in cultivation and genetic engineering techniques provide prospective approaches to widen their application for food. However, there are currently problems in the microalgae food industry in terms of assessing nutritional value, selecting processes for microalgae culture, obtaining suitable commercial strains of microalgae, etc. Additionally, the limitations of real data of market opportunities for microalgae make it difficult to assess their actual potential and to develop a better industrial chain. This review addresses the current status of the microalgae food industry, the process of commercializing microalgae food and breeding methods. Current research progress in addressing the limitations of microalgae industrialization and future prospects for developing microalgae food products are discussed.

Front Cardiovasc Med 2022; 9:1009726.

Abstract
BACKGROUND Sepsis-induced cardiomyopathy (SIC) is one major cause of death for sepsis but lacks timely diagnosis and specific treatment due to unclear mechanisms. Lipocalin-2 (LCN-2) is a key regulator of lipid metabolism which has been recently proved closely related to sepsis, however, the relationship between LCN-2 and septic myocardial injury remains unknown. We aim to explore the role of LCN-2 in the pathological progress of SIC based on clinical and laboratory evidence. METHODS Consecutive patients admitted to the intensive care unit (ICU) from August 2021 to April 2022 fulfilling the criteria of severe sepsis were included. The level of LCN-2 in plasma was assayed and analyzed with clinical characteristics. Biostatistical analysis was performed for further identification and pathway enrichment. Mouse model for SIC was thereafter established, in which plasma and tissue LCN-2 levels were tested. RNA sequencing was used for verification and to reveal the possible mechanism. Mitochondrial function and intracellular lipid levels were assayed to further assess the biological effects of targeting LCN-2 in cardiomyocytes with small interference RNAs (siRNAs). RESULTS The level of LCN-2 in plasma was markedly higher in patients with severe sepsis and was associated with higher cardiac biomarkers and lower LVEF. In the in vivo experiment, circulating LCN-2 from plasma was found to increase in SIC mice. A higher level of LCN-2 transcription in myocardial tissue was also found in SIC and showed a clear time relationship. RNA sequencing analysis showed the level of LCN-2 was associated with several gene-sets relevant to mitochondrial function and lipid metabolism-associated pathways. The suppression of LCN-2 protected mitochondrial morphology and limited the production of ROS, as well as restored the mitochondrial membrane potential damaged by LPS. Neutral lipid staining showed prominent lipid accumulation in LPS group, which was alleviated by the treatment of siLCN2. CONCLUSION The level of LCN-2 is significantly increased in SIC at both circulating and tissue levels, which is correlated with the severity of myocardial injury indicators, and may work as an early and great predictor of SIC. LCN-2 probably participates in the process of septic myocardial injury through mediating lipid accumulation and affecting mitochondrial function.

Abstract
BACKGROUND AND PURPOSE Flow diversion has gradually become a standard treatment for intracranial aneurysms of the anterior circulation. Recently, the off-label use of the flow diverters to treat posterior circulation aneurysms has also increased despite initial concerns of rupture and the suboptimal results. This study aimed to explore the change in complication rates and treatment outcomes across time for posterior circulation aneurysms treated using flow diversion and to further evaluate the mechanisms and variables that could potentially explain the change and outcomes. MATERIALS AND METHODS A retrospective review using a standardized data set at multiple international academic institutions was performed to identify patients with ruptured and unruptured posterior circulation aneurysms treated with flow diversion during a decade spanning January 2011 to January 2020. This period was then categorized into 4 intervals. RESULTS A total of 378 procedures were performed during the study period. Across time, there was an increasing tendency to treat more vertebral artery and fewer large vertebrobasilar aneurysms (P = .05). Moreover, interventionalists have been increasingly using fewer overlapping flow diverters per aneurysm (P = .07). There was a trend toward a decrease in the rate of thromboembolic complications from 15.8% in 2011-13 to 8.9% in 2018-19 (P = .34). CONCLUSIONS This multicenter experience revealed a trend toward treating fewer basilar aneurysms, smaller aneurysms, and increased usage of a single flow diverter, leading to a decrease in the rate of thromboembolic and hemorrhagic complications.

Abstract
The aging microenvironment serves important roles in cancers. However, most studies focus on circumscribed hot spots such as immunity and metabolism. Thus, it is well ignored that the aging microenvironment contributes to the proliferation of tumor. Herein, we established three prognosis-distinctive aging microenvironment subtypes, including AME1, AME2, and AME3, based on aging-related genes and characterized them with “Immune Exclusion,” “Immune Infiltration,” and “Immune Intermediate” features separately. AME2-subtype tumors were characterized by specific activation of immune cells and were most likely to be sensitive to immunotherapy. AME1-subtype tumors were characterized by inhibition of immune cells with high proportion of Catenin Beta 1 (CTNNB1) mutation, which was more likely to be insensitive to immunotherapy. Furthermore, we found that CTNNB1 may inhibit the expression of C-C Motif Chemokine Ligand 19 (CCL19), thus restraining immune cells and attenuating the sensitivity to immunotherapy. Finally, we also established a robust aging prognostic model to predict the prognosis of patients with hepatocellular carcinoma. Overall, this research promotes a comprehensive understanding about the aging microenvironment and immunity in hepatocellular carcinoma and may provide potential therapeutic targets for immunotherapy.

Abstract
Chronic exposure to low-dose bisphenol A (BPA) has become a global problem of public health. Our previous work showed that low-dose BPA exposure caused gut microbial dysbiosis and hepatic steatosis. Curcumin, a polyphenol extracted from turmeric, has an inhibitory effect on liver lipid accumulation, whether curcumin can alleviate BPA-induced hepatic steatosis through improving intestinal flora and modulating gut-liver axis remains to be elucidated. Male CD-1 mice were fed with BPA-contaminated diet supplemented with or not with curcumin for 24 weeks. Curcumin supplementation markedly ameliorated liver fat accumulation and hepatic steatosis induced by BPA. Gut microbiota analysis via 16S rRNA sequencing revealed that the relative abundance of Proteobacteria and Firmicutes/Bacteroidetes ratio were increased in BPA-fed mice, and this alteration was reversed by curcumin treatment. Akkermansia, which was recognized as a potential probiotic, was significantly reduced after BPA exposure and was restored to the control level with curcumin addition. Furthermore, curcumin supplementation reversed the down-regulation of intestinal tight junction protein expressions (zona occludens-1 and occludin), improved increased gut permeability, reduced serum lipopolysaccharide level and suppressed the activation of hepatic toll-like receptor 4 / nuclear factor-κB (TLR4/NF-κB) pathway induced by BPA. These results indicated that the protective effect of curcumin against hepatic steatosis induced by BPA and further revealed that its mechanism might be its prebiotic effect on maintaining intestinal flora homeostasis and improving intestinal barrier function, consequently reducing serum lipopolysaccharide-triggered inflammatory response in the liver. Our work provides evidence for curcumin as a potential nutritional therapy for BPA-mediated hepatic steatosis.

Abstract
Objective: To explore and analyze the correlation between labial gingival morphology and alveolar bone morphology of maxillary anterior teeth in patients with posterior dental implant, so as to provide reference basis for restoration design and esthetic reconstruction of anterior teeth. Methods: Sixty-four patients [24 males, 40 females (25.6±3.3) years old] who planned to receive posterior dental implant restoration were recruited randomly with the inclusion and exclusion criteria in Department of Prosthodontics, School of Stomatology, The Fourth Military Medical University from May 2020 to May 2021. According to the visibility of periodontal probe through gingival margin, the subjects were divided into thin and thick gingival biotypes, including 29 cases of thin biotype and 35 cases of thick biotype. The 3Shape software was used to perform oral scanning, and cone beam CT (CBCT) was taken for each patient. Geomagic and Mimics software were used to measure and record the labial crown width and length, gingival papilla height, gingival angle, bone papilla height and bone margin angle of maxillary anterior teeth. Results: The crown width length ratios of maxillary central incisors, lateral incisors and canines were 0.85±0.08, 0.80±0.08 and 0.86±0.09 (F=10.71, P<0.01). The height of gingival papilla between maxillary central incisors, between central incisors and lateral incisors, between lateral incisors and canines were (3.93±0.86), (3.47±0.84) and (3.38±0.91) mm respectively (F=7.44, P<0.01), and the height of corresponding bone papilla were (3.44±0.88), (3.12±0.75) and (2.72±0.63) mm respectively (F=14.26, P<0.01). The gingival margin angles of maxillary central incisors, lateral incisors and canines were 88.3°±7.7°, 84.7°±8.9° and 81.2°±6.6° (F=13.15, P<0.01), and the bone margin angles were 103.2°±13.1°, 99.5°±11.2° and 110.6°±13.0° (F=13.25, P<0.01). The crown width length ratio (0.81±0.08), gingival margin angle (82.2°±7.4°) and bone margin angle (99.4°±12.9°) of thin gingival subjects were significantly lower than those of thick gingival subjects (0.85±0.09, 86.5°±8.6°, 108.5°±11.4°) (t=-2.79, 3.63, 5.20, P<0.01). The height of gingival papilla [(3.93±0.81) mm] and bone papilla [(3.43±0.80) mm] in thin gingival subjects were significantly lower than those in thick gingival subjects [(3.34±0.84) and (2.85±0.71) mm, respectively] (t=-4.89, -5.36, P<0.01). The height of labial gingival papilla of upper anterior teeth was positively correlated with that of bone papilla in all patients (r=0.66, P<0.01); the ratio of crown width to length of upper anterior teeth was positively correlated with the angle of bone margin (r=0.42, P<0.01); the height of anterior gingival papilla was negatively correlated with the angle of bone margin (r=-0.58, P<0.01), and the height of bone papilla was negatively correlated with the angle of bone margin (r=-0.82, P<0.01). Conclusions: The crown shape, gingival shape and alveolar bone shape of maxillary anterior teeth were different in different tooth positions. Patients with different periodontal phenotypes had different crown width length ratio, gingival papilla height, bone papilla height, gingival margin angle, and bone margin angle.

Abstract
Objective: To investigate the efficacy and safety of enhanced recovery after surgery (ERAS) in perioperative management of patients with gallbladder carcinoma. Methods: The data of the patients with gallbladder carcinoma admitted at Peking Union Medical College Hospital between January 2017 and December 2021 were analyzed retrospectively. There were 69 males(42.1%) and 95 females(57.9%),with age of (64.0±10.3) years(range:37 to 89 years). Patients were divided into ERAS group(n=53) and normal group(n=111) according to whether they were treated with ERAS measures during the perioperative period.The basic characteristics of the two groups were matched by propensity score matching,and then the perioperative information was compared between the two groups. Categorical variables were presented as absolute numbers or frequencies. Differences between study groups were analyzed using χ2 test, Fisher's exact test, t-test, or Mann-Whitney U test, as appropriate. Results: Each group had 45 patients after propensity score matching with well-balanced basic characteristics. There was no difference in basic characteristics, operation time,bleeding,complication,and hospitalization expenses between two groups(all P>0.05). Compared with the normal group,time of ambulation (M(IQR)) (1(1) day vs. 2(2) days;Z=-3.839,P<0.01),postoperative anal exhaust time (2(1) days vs. 3(1) days;Z=-3.013,P=0.003),feeding time(2(1) days vs. 2(1) days;Z=-3.647,P<0.01),postoperative (5(2) days vs. 7(4) days;Z=-3.984,P<0.01) and total(8(4) days vs. 13(6) days;Z=-3.605,P<0.01) hospitalization time were shorter in ERAS group. Postoperative complications occurred in 12 patients. According to the Clavien-Dindo classification,6,4,and 2 patients were classified as grade Ⅰ,Ⅱ,and Ⅲa,respectively. Conclusion: The ERAS measures is safe and effective for perioperative management of patients with gallbladder carcinoma, enhancing patient recovery and shortening hospitalization time without increasing complication or hospitalization cost.

Abstract
The involvement of cardiomyopathy during sepsis means higher mortality and prolonged length of hospital stay. Many efforts have been made to alleviate the apoptosis of cardiomyocytes in sepsis. The huge potential of IL-13 in tissue repair has attracted increasing attention. In the present study, we used LPS-treated mice or primary cardiomyocytes as a sepsis model to explore the anti-apoptotic ability of IL-13. It was found that an increased level of exogenous IL-13 was beneficial to the recovery of heart function in sepsis, and this anti-apoptotic effect of IL-13 was probably through enhancing the phosphorylation of STAT3 Ser727. In addition, we identified that the heart protective effect of IL-13 was associated with type 2 innate lymphocytes (ILC2). All these findings may provide a potential promising treatment for sepsis-induced cardiomyopathy.

Abstract
Sepsis-induced cardiac injury (SIC) is one of the most common complications in the intensive care unit (ICU) with high morbidity and mortality. Mitochondrial dysfunction is one of the main reasons for SIC, and Interleukin-13 (IL-13) is a master regulator of mitochondria biogenesis. The aim of the present study was to investigate the role of IL-13 in SIC and explore the underlying mechanism. It was found that reactive oxygen species (ROS) production and apoptosis were significantly increased in lipopolysaccharide (LPS)-stimulated primary cardiomyocytes, which was accompanied with obvious mitochondria dysfunction. The results of RNA-sequencing (RNA-seq), mitochondrial membrane potential, fatty acid uptake and oxidation rate suggested that treatment with IL-13 could restore the function and morphology of mitochondria, indicating that it played an important role in protecting septic cardiomyocytes. These findings demonstrated that IL-13 alleviated sepsis-induced cardiac inflammation and apoptosis by improving mitochondrial fatty acid uptake and oxidation, suggesting that IL-13 may prove to be a potential promising target for SIC treatment.

Abstract
Protection of cardiomyocytes against oxidative stress is vital to alleviate myocardial ischemia/reperfusion injury (MI/RI). However, antioxidative treatment is hampered by the lack of safe and effective therapeutics. Polydopamine (PDA), as a biodegradable class of nanomaterial with excellent antioxidant properties, has shown great potential in treating MI/RI. To achieve site-specific antioxidative efficacy, we established a PDA-based biomimetic nanoplatform (PDA@M), which consisted of a polydopamine core and a macrophage membrane shell to form a shell-core structure. By inheriting the inherent migration capability of macrophages, PDA@M was able to target the infarcted myocardium and exert an antioxidative effect to protect the myocardium. The results demonstrated that the accumulation of the membrane-wrapped nanoparticles (NPs) in the infarcted myocardium was greatly increased as compared with PDA alone, which effectively relieved the MI/RI-induced oxidative stress. PDA@M largely decreased the infarct size and improved the cardiac function post-MI/RI. Our study revealed that PDA@M could inhibit cell pyroptosis by suppressing the NLRP3/caspase-1 pathway, which is known to play a significant role in the antioxidant signaling pathway. In summary, PDA@M can target the infarcted myocardium and exert antioxidative and antipyroptosis functions to protect the myocardium against MI/RI-induced oxidative stress, suggesting that it may prove to be a potential therapeutic agent for MI/RI.

Abstract
We recently reported that the risk of sexually acquired HIV-1 infection is increased significantly by variants in the gene encoding CD101, a protein thought to modify inflammatory responses. Using blood samples from individuals with and without these variants, we demonstrate that CD101 variants modify the prevalence of circulating inflammatory cell types and show that CD101 variants are associated with increased proinflammatory cytokine production by circulating T cells. One category of CD101 variants is associated with a reduced capacity of regulatory T cells to suppress T cell cytokine production, resulting in a reduction in the baseline level of immune quiescence. These data are supported by transcriptomics data revealing alterations in the intrinsic regulation of antiviral pathways and HIV resistance genes in individuals with CD101 variants. Our data support the hypothesis that CD101 contributes to homeostatic regulation of bystander inflammation, with CD101 variants altering heterosexual HIV-1 acquisition by facilitating increased prevalence and altered function of T cell subsets.

Abstract
Pharmacologic inhibition of PARP is the primary therapeutic strategy for BRCA mutant ovarian cancer. However, most of patients carry wild-type BRCA1/2 with no significant clinical benefits from PARP inhibitors, calling for the needs to further understanding and developing new strategy when employing PARP inhibitors to treat ovarian cancer. Here, we show that ferroptosis, a form of regulated cell death driven by iron-dependent phospholipid peroxidation, is partly responsible for the efficacy of PARP inhibitor olaparib. Mechanistically, pharmacological inhibition or genetic deletion of PARP downregulates the expression of cystine transporter SLC7A11 in a p53-dependent manner. Consequently, decreased glutathione biosynthesis caused by SLC7A11 repression promotes lipid peroxidation and ferroptosis. Furthermore, ferroptosis perturbation results in significant resistance to olaparib without affecting DNA damage response, while boosting ferroptosis by ferroptosis inducers (FINs) synergistically sensitizes BRCA-proficient ovarian cancer cells and xenografts to PARP inhibitor. Together, our results reveal a previously unappreciated mechanism coupling ferroptosis to PARP inhibition and suggest the combination of PARP inhibitor and FINs in the treatment of BRCA-proficient ovarian cancer.

Abstract
Ferroptosis, a form of regulated cell death triggered by lipid peroxidation, was recently identified as an important mechanism in radiotherapy (RT)-mediated tumor suppression and radioresistance, although the exact genetic contexts in which to target ferroptosis in RT remains to be defined. p53 is the most commonly mutated gene in human cancers and a major effector to RT. Here, we identify ferroptosis as a critical mechanism to mediate p53 function in tumor radiosensitivity. Mechanistically, RT-mediated p53 activation antagonizes RT-induced SLC7A11 expression and represses glutathione synthesis, thereby promoting RT-induced lipid peroxidation and ferroptosis. p53 deficiency promotes radioresistance in cancer cells or tumors at least partly through SLC7A11-mediated ferroptosis inhibition. Ferroptosis inducers (FINs) that inhibit SLC7A11 exert significant radiosensitizing effects in tumor organoids and patient-derived xenografts with p53 mutation or deficiency. Finally, we show that RT-induced ferroptosis correlates with p53 activation and better clinical outcomes to RT in cancer patients. Together, our study uncovers a previously unappreciated role of ferroptosis in p53-mediated radiosensitization and suggest using FINs in combination with RT to treat p53-mutant cancers.

Abstract
We reviewed studies comparing survival outcomes such as overall survival (OS), progression free survival (PFS), and toxicity profile between patients treated with Pegylated Liposomal Doxorubicin (PLD) combination and those treated with paclitaxel combination for ovarian cancer. We conducted systematic searches in various databases including Medline, Cochrane Controlled Register of Trials (CENTRAL), ScienceDirect, and Google Scholar from inception until August 2019. We used the Cochrane risk of bias tool to assess the quality of published trials. We carried out a meta-analysis with random-effects model and reported pooled Hazard ratios (HR) or Risk ratios (RR) with 95% confidence intervals (CIs). In total, we analysed 7 studies including 3,676 participants. All the studies were randomized controlled trials, while majority of studies had low bias risks. We did not find significant evidence for any of these outcomes except progression free survival (favoured PLD combination therapy pooled HR=0.87; 95% CI: 0.77-0.98). Worst grade toxicities like allergy (pooled RR: 1.86; 95% CI: 1.06-3.24) and neurotoxicity (pooled RR: 5.59; 95% CI: 1.43-21.84) were significantly higher among patients receiving paclitaxel combination therapy when compared to patients receiving PLD combination therapy. To summarize, PLD combination therapy is non-inferior to paclitaxel combination therapy in the management of ovarian cancer with respect to survival outcomes and worst grade toxicity profile. However, clinical recommendations cannot be made, as the evidence is not conclusive or significant enough.

Abstract
The aim of this study was to investigate the effects of chromatin-remodeling genes on the prognosis of patients with clear cell renal cell carcinoma (ccRCC). In TCGA-KIRC patients, two subgroups based on 86 chromatin-remodeling genes were established. The random forest algorithm was used for feature selection to identify BPTF, SIN3A and CNOT1 as characterized chromatin remodelers in ccRCC with good prognostic value. YY1 was indicated to be a transcription factor of genes highly related to BPTF, SIN3A and CNOT1. Functional annotations indicated that BPTF, SIN3A, CNOT1 and YY1 are all involved in the ubiquitin-mediated proteolysis process and that high expression of any of the five associated E3 ubiquitin ligases found in the pathway suggests a good prognosis. Protein network analysis indicated that BPTF has a targeted regulatory effect on YY1. Another independent dataset from International Cancer Genome Consortium (ICGC) showed a strong consistency with results in TCGA. In conclusion, we demonstrate that BPTF, SIN3A and CNOT1 are novel prognostic factors that predict good survival in ccRCC. We predicted that the good prognostic value of chromatin-remodeling genes BPTF and SIN3A is related to the regulation of YY1 and that YY1 regulates E3 ubiquitin ligases for further degradation of oncoproteins in ccRCC.

Abstract
The lattice dynamics and high-temperature structural transition in SnS and SnSe are investigated via inelastic neutron scattering, high-resolution Raman spectroscopy and anharmonic first-principles simulations. We uncover a spectacular, extreme softening and reconstruction of an entire manifold of low-energy acoustic and optic branches across a structural transition, reflecting strong directionality in bonding strength and anharmonicity. Further, our results solve a prior controversy by revealing the soft-mode mechanism of the phase transition that impacts thermal transport and thermoelectric efficiency. Our simulations of anharmonic phonon renormalization go beyond low-order perturbation theory and capture these striking effects, showing that the large phonon shifts directly affect the thermal conductivity by altering both the phonon scattering phase space and the group velocities. These results provide a detailed microscopic understanding of phase stability and thermal transport in technologically important materials, providing further insights on ways to control phonon propagation in thermoelectrics, photovoltaics, and other materials requiring thermal management.

Abstract
In conventional quasi-one-dimensional antiferromagnets with quantum spins, magnetic excitations are carried by either magnons or spinons in different energy regimes: they do not coexist independently, nor could they interact with each other. In this Letter, by combining inelastic neutron scattering, quantum Monte Carlo simulations, and random phase approximation calculations, we report the discovery and discuss the physics of the coexistence of magnons and spinons and their interactions in Botallackite-Cu_{2}(OH)_{3}Br. This is a unique quantum antiferromagnet consisting of alternating ferromagnetic and antiferromagnetic spin-1/2 chains with weak interchain couplings. Our study presents a new paradigm where one can study the interaction between two different types of magnetic quasiparticles: magnons and spinons.

Abstract
Bladder cancer (BC) is one of the most common malignancies in terms of incidence and recurrence worldwide. The aim of this study was to identify novel prognostic biomarkers related to BC progression utilizing weighted gene co-expression network analysis (WGCNA) and further bioinformatic analysis. First, we constructed a co-expression network by using WGCNA among 274 TCGA-BLCA patients and preliminarily screened out four genes (CORO1C, TMPRSS4, PIK3C2B, and ZNF692) associated with advanced clinical traits. In support, GSE19915 and specimens from 124 patients were used to validate the genes selected by WGCNA; then, CORO1C and TMPRSS4 were confirmed as hub genes with strong prognostic values in BC. Moreover, the result of gene set enrichment analysis (GSEA) and gene set variation analysis (GSVA) indicated that CORO1C and TMPRSS4 might be involved in the process of epithelial to mesenchymal transition (EMT) reversely. In addition, high expression of CORO1C was found to be significantly correlated with tumor-infiltrating neutrophils (TINs), a negative regulatory component that facilitates tumor distant progression and induces poor clinical outcome. In conclusion, our study first identified CORO1C and TMPRSS4 as vital regulators in the process of tumor progression through influencing EMT and could be developed to effective prognostic and therapeutic targets in future BC treatment.

Abstract
Great progress has been made in miRNA nanodelivery for the treatment of myocardial infarction (MI). However, miRNA nanodelivery within the infarct is impeded by microvascular obstruction as a local circulatory disorder caused by microthrombus formation in microvessels. Knowing that low molecular weight heparin (LMWH) can effectively prevent microthrombus formation in microcirculation, it is hypothesized whether surface modification of the nanocarrier with LMWH can overcome microvascular obstruction in the infarct area for better miRNA delivery. Herein, a novel nanocomlex consisting of dendrigraft poly-l-lysine (DGL)-loaded miR-1 inhibitor as the core to decrease apoptosis of cardiomyocytes and LMWH as the shell to overcome microvascular obstruction of the infarct area is developed. The results show that this anti-coagulative nanocomlex is able to reduce microthrombus formation in microvessels and inhibit blood-coagulation factor Xa, thereby overcoming microvascular obstruction in the infarct area. In addition, it further enhances the uptake of miR-1 inhibitor within the infarct and decreases myocardiocyte apoptosis, thus improving the cardiac function and attenuating the myocardial fibrosis. In conclusion, modification of DGL-loaded miR-1 inhibitor with LMWH helps overcome microvascular obstruction in delivering the drug to the infarct area, thus providing a promising therapeutic strategy for achieving a better therapeutic outcome of MI.

Abstract
OBJECTIVE Activated (CD38HLA-DR) PD-1 CD4 T cells are strongly associated with virus replication and disease progression in untreated HIV-1 infection, and viral persistence in individuals on ART. Few studies have examined cell-associated viral load (CAVL) in different activated CD4 T-cell populations to measure relative contributions to viral reservoirs. DESIGN Longitudinal assessment of HIV-1 chronically infected Ugandans initiating ART, to investigate activated CD4 T-cell populations and their contribution to viral reservoirs. METHODS We followed 32 HIV-1 chronically infected individuals from Kampala, Uganda, and determined their CD4 T-cell counts and viral load at baseline, 6, and 12 months after the initiation of ART. T-cell populations were sorted based on activation profiles and gag DNA was measured to determine CAVL within these populations. Soluble factors associated with inflammation were measured in plasma using a multiplexed platform. RESULTS Concomitant with viral load decline and CD4 T-cell count rebound, the activated PD-1 CD4 T-cell population contracted upon initiation of ART. Baseline levels of activated PD-1 CD4 T cells correlated with plasma levels of IP-10 and TNFRII. Interestingly, a higher baseline level of activated PD-1 CD4 T cells was associated with poorer CD4 T-cell recovery after 12 months of ART. This population contributed significantly to the cell-associated HIV DNA load at baseline, whereas their contribution declined on ART, indicating high turnover. CONCLUSION Activated PD-1 CD4 T cells are predictors of poor immunologic recovery on ART and may represent a short-lived component of HIV-1 reservoirs.

Abstract
OBJECTIVE To compare the effects of letrozole and human menopausal gonadotropin (HMG) in the treatment of patients with polycystic ovary syndrome (PCOS) resistant to clomiphene citrate (CC). METHODS A total of 96 clomiphene resistance polycystic ovary syndrome patients infertility were randomly divided into an LE group, and HMG group (n = 48). LE group orally received letrozole at 5.0 mg/d on the 3rd-5th days of menstrual cycle for 5 consecutive days, and 75 U/d HMG was given through intramuscular injection for 5 days starting from the third day of menstrual cycle in HMG group. Number of growing and mature follicles, serum E2 (pg/mL), serum P (ng/mL), endometrial thickness, occurrence of pregnancy and miscarriage were observed. RESULTS There was no significant difference in the number of ovulation cycles between the 2 groups (53.6% vs 64.7%, P > .05). The number of mature follicular cycles in the HMG group was higher than that of the letrozole group (P < .01). There were no significant differences in the clinical pregnancy rate (22.9% vs 27.1%, P > .05) and abortion rate (6.2% vs 10.4%, P > .05). There was no significant difference in the endometrial thickness between the 2 groups on the day of HCG injection [(9.1 ± 0.2) mm vs (10.7 ± 1.6) mm, P > .05]; the serum estradiol (E2) was lower in the letrozole group. The incidence of ovarian cysts was lower than that of HMG group (P < .05). There was2 ovarian hyperstimulation syndrome in the letrozole group; the incidence of ovarian hyperstimulation syndrome in the HMG group was 12.5%. CONCLUSION Letrozole-induced ovulation can obtain ovulation rate and pregnancy rate similar to gonadotropin, but reduce the risk associated with treatment. It can be used as an effective ovulation option for patients with polycystic ovary syndrome who are resistant to clomiphene.

Abstract
OBJECTIVE To investigate the effects of ketamine on autophagy and apoptosis of astrocytes in the cerebral cortex of rats, and determine whether nuclear factor-κB (NF-κB) pathway is involved in the regulation of autophagy and apoptosis of astrocytes. MATERIALS AND METHODS A total of 36 male Sprague-Dawley (SD) rats were randomly divided into 3 groups: control group (Group C: intraperitoneal injection of equal amount of normal saline), glutamic acid group (Group G: intraperitoneal injection of 1 mg/kg glutamic acid) and glutamic acid + ketamine group (Group GK: intraperitoneal injection of 1 mg/kg glutamic acid and then injection of 5 mg/kg ketamine after 30 min). The cerebral cortex of rats in each group was taken after successive administration for 5 d. The number of glial fibrillary acidic protein (GFAP)-positive cells in the cerebral cortex of rats in each group was detected via immunofluorescence. The number of terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)-positive cells (apoptotic cells) in the cerebral cortex was detected via TUNEL staining. The levels of inflammatory factors were detected using the enzyme-linked immunosorbent assay (ELISA) kit. Moreover, the expressions of autophagy-related proteins and apoptosis-related proteins in the cerebral cortex were detected via Western blotting, and the expressions of IκB-a and NF-κBp65 were also detected. RESULTS The results of immunofluorescence showed that the number of GFAP-positive cells in the cerebral cortex of rats in Group G was significantly increased compared with that in Group C (p<0.01), and it was significantly decreased in Group GK compared with that in Group G (p<0.01). The results of TUNEL staining revealed that the number of TUNEL-positive cells in the cerebral cortex in Group G was significantly larger than that in Group C, and it was significantly smaller in Group GK than that in Group G (p<0.01). Results of ELISA demonstrated that compared with those in Group C, the contents of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) in Group G were significantly increased (p<0.01), but the content of IL-10 was significantly decreased (p<0.01). Compared with those in Group G, the contents of IL-6 and TNF-a in Group GK were significantly decreased (p<0.01), but the level of IL-10 was statistically elevated (p<0.01). Compared with those in Group C, the levels of LC3 II/I and cleaved caspase-3 in the cerebral cortex in Group G were significantly increased (p<0.01), but the p62 level and B-cell lymphoma-2/Bcl-2 associated X protein (Bcl-2/Bax) ratio were significantly decreased (p<0.01). In Group GK, the levels of LC3 II/I and cleaved caspase-3 were reduced, but the p62 level and Bcl-2/Bax ratio were increased. The expressions of IκB-α and NF-κBp65 in Group G were significantly decreased compared with those in Group C (p<0.01), and they were significantly higher in Group GK than those in Group G (p<0.01). CONCLUSIONS Ketamine can reduce the glutamic acid-induced activation of astrocytes in the cerebral cortex, inhibit the autophagy and alleviate the apoptosis of astrocytes, the process of which is mediated by the NF-κB pathway, which provides the new molecular basis of ketamine in protecting astrocytes.

Abstract
BACKGROUND Pre-exposure prophylaxis (PrEP) with emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) reduces the risk of HIV seroconversion but may promote bone mineral density (BMD) decline. The mechanisms of BMD decline with FTC/TDF remain unclear, and studies in HIV-positive individuals have been confounded by the effects of HIV and concomitant antiretroviral medications. We evaluated the impact of FTC/TDF on biomarkers of bone remodeling and bone mineral metabolism in HIV-negative men and women enrolled in the Partners PrEP Study. METHODS In a random sample of HIV-negative participants randomized to FTC/TDF PrEP (n = 50) or placebo (n = 50), serum parathyroid hormone (PTH), bone biomarkers (C-telopeptide, procollagen 1 intact N-terminal propeptide, and sclerostin), and plasma fibroblast growth factor 23 were measured at baseline and month 24, and the percentage change was compared between groups. In a complementary analysis, we compared the change in biomarkers between participants with and without a 25% decline in glomerular filtration rate (GFR) on FTC/TDF. RESULTS Baseline characteristics were similar between the groups (median age, 38 years; 40% women). Vitamin D insufficiency was common, but baseline GFR and PTH were in the normal range. We observed a significantly greater percent increase in serum C-telopeptide in participants randomized to FTC/TDF vs placebo (P = .03), suggesting an increase in bone remodeling. We observed no differences in the other biomarkers, or in a separate analysis comparing participants with and without a decline in GFR. CONCLUSIONS Increased bone remodeling may mediate the BMD decline observed with tenofovir-containing PrEP and antiretroviral therapy, independent of a TDF-mediated decrease in kidney function.

Abstract
Fenvalerate (FEN), a pyrethroid insecticide used worldwide, has been shown to produce a potentially adverse effect on male reproduction. However the mechanisms are not completely understood. Thus this study aimed to (1) determine whether cellular apoptosis was involved in FEN-induced testicular damage in rats, and (2) identify the potential mechanism involved in FEN-induced apoptosis in testes. Data demonstrated that FEN markedly decreased serum testosterone levels, increased the inner diameter of seminiferous tubules, decreased the layers of spermatogenic cells, disturbed spermatogenesis and increased the number of apoptotic cells. Further, bioinformatic analysis of gene microarray in rat testis tissue showed that FEN significantly altered the expressions of genes (Krt8, Mal, Cd24, Lcn2, Phlda1, Arg2) related to apoptotic related processes. The expression pattern of these 6 genes was upregulated in FEN-treated rat testicular tissue. qRT-PCR analysis demonstrated that Phlda1, a well-documented pro-apoptotic factor, was significantly elevated by FEN. The expression of PHLDA1 testicular protein was also elevated following FEN exposure. In conclusion, our results suggest that FEN exposure induced deleterious effects on rat testes associated with Phlda1-mediated apoptosis which may act as a molecular mechanism underlying FEN induced rat testicular damage.

Abstract
Chronic HIV-1 is associated with increased levels of FcγRIIIA+ CD8 T cells. FcγRIIIA+ CD8 T cells display an innate transcriptomic profile akin to NK cells. ADCC is mediated by FcγRIIIA+ CD8 T cells at levels comparable with NK cells.
HIV-1 infection expands large populations of late-stage differentiated CD8 T cells that may persist long after viral escape from TCR recognition. In this study, we investigated whether such CD8 T cell populations can perform unconventional innate-like antiviral effector functions. Chronic untreated HIV-1 infection was associated with elevated numbers of CD45RA+CD57+ terminal effector CD8 T cells expressing FcγRIIIA (CD16). The FcγRIIIA+ CD8 T cells displayed a distinctive transcriptional profile between conventional CD8 T cells and NK cells, characterized by high levels of IKZF2 and low expression of IL7R. This transcriptional profile translated into a distinct NKp80+ IL-7Rα− surface phenotype with high expression of the Helios transcription factor. Interestingly, the FcγRIIIA+ CD8 T cells mediated HIV-specific Ab-dependent cellular cytotoxicity (ADCC) activity at levels comparable with NK cells on a per cell basis. The FcγRIIIA+ CD8 T cells were highly activated in a manner that correlated positively with expansion of the CD8 T cell compartment and with plasma levels of soluble mediators of antiviral immunity and inflammation such as IP-10, TNF, IL-6, and TNFRII. The frequency of FcγRIIIA+ CD8 T cells persisted as patients initiated suppressive antiretroviral therapy, although their activation levels declined. These data indicate that terminally differentiated effector CD8 T cells acquire enhanced innate cell-like characteristics during chronic viral infection and suggest that HIV-specific ADCC is a function CD8 T cells use to target HIV-infected cells. Furthermore, as the FcγRIIIA+ CD8 T cells persist in treatment, they contribute significantly to the ADCC-capable effector cell pool in patients on antiretroviral therapy.

Abstract
In recent years, various vaccination strategies have shed new light on the treatment of atherosclerosis. Proprotein convertase subtilisin/Kexin type 9 (PCSK9) is a hot target in the development of antiatherosclerosis vaccine. However, the efficacy of conventional PCSK9 is largely limited by poor immunogenicity and low hapten density. Therefore, we hypothesized whether a nanostructure synthesized by self-assembled carrier protein accompanied by multicopy hapten display could improve the efficacy of vaccine. In this study, bovine serum albumin (BSA) was self-assembled into sub-100 nm nanoparticles via an intermolecular disulfide network as the inner core. Then, sequences of PCSK9 were conjugated onto the surface of nanoparticles by "click" chemistry to consequently form an orderly structured of nanovaccine with repetitive hapten display. Compared with conventional PCSK9 peptide vaccine, our immunization study demonstrated that the PCSK9 multicopy display nanovaccine (PMCDN) was able to induce higher titers of PCSK9 antibody and more efficient lymph node drainage and improve endocytosis by antigen presenting cells.
