Abstract
With the rapid development of the economy, people have increasingly higher requirements for the comfort of living spaces, and the result is the sharp increase in building energy consumption. Several design parameters influence living space comfort and building energy efficiency. Since the same design standard can include different design parameter combinations, synergic relationships may exist between these criteria for one case. Identifying these synergic relationships requires an inverse problem approach. This paper established a model by combining an improved genetic algorithm (IGA) and numerical calculation to determine the synergic design parameter relationships (e.g. the thermophysical building material properties and energy-saving factors). For [Formula: see text], the shading coefficient significantly influenced the linear function between the thermal conductivity and insulation thickness. In this case, the insulation thickness was exponentially related to the shading coefficient, while the thermal conductivity of the insulation material significantly impacted the synergic relationship. For [Formula: see text], the insulation thickness was a segmented function of the shading coefficient. The results verified that the proposed model was efficient and reliable for identifying the synergic relationships between energy-saving parameters. In engineering applications, designers can select the optimal design parameter combination based on the relationship curve between the parameters in this paper according to the local market conditions and specific design requirements.

Abstract
OBJECTIVE This article aims to investigate the clinical value of hemoglobin/red cell distribution width ratio (Hb/RDW), C-reactive protein/albumin ratio (CAR) and plateletcrit (PCT) combined with carcinoembryonic antigen (CEA) in colorectal cancer (CRC) auxiliary diagnosis. METHODS We retrospectively analyzed in 718 subjects (212 with CRC, 209 with benign colorectal lesions (BCL), 111 with other cancers, and 186 healthy controls). RESULTS The CAR, PCT, and CEA in the CRC group were higher than those in the BCL, other cancers, and the healthy control group. However, Hb/RDW in the CRC group was lower than the other three groups. Moreover, there were significant differences in Hb/RDW and CEA among different T-N-M stages (all P< 0.05). Multivariate logistic regression showed that low level of Hb/RDW and high level of CAR, CEA, PCT were risk factors for CRC, and are correlated with CRC stage. Additionally, the area under the receiver operating characteristic curve (AUC) of Hb/RDW+CEA (AUC: 0.735), CAR+CEA (AUC: 0.748), PCT+CEA (AUC: 0.807) was larger than that of Hb/RDW (AUC: 0.503), CAR (AUC: 0.614), or PCT (AUC: 0.713) alone (all P< 0.001) in distinguishing CRC from BCL. CONCLUSIONS Hb/RDW, CAR, PCT, and CEA are independent risk factors for CRC. Hb/RDW, CAR, and PCT combined with CEA have significant value for auxiliary differential diagnosis of CRC and BCL.

Abstract
The mitogen-activated protein kinases family of genes plays a crucial role in a wide range of inflammatory responses in the human body. The MAPK family of genes includes ERK, ERK5, JNK, P-38 mitogen-activated protein kinases. However, the correlation between MAPK family gene expression and pan-cancer prognosis, as well as the tumor microenvironment, has not been extensively studied. This study integrated multiple bioinformatics analysis methods to assess the expression and prognostic value of MAPK family genes, as well as their relationship with tumor microenvironment in patients with pan-cancer. The results showed that ERK, JNK, and P-38 MAPK expression were found to be significantly upregulated in rectum adenocarcinoma (READ), colon adenocarcinoma/rectum adenocarcinoma esophageal carcinoma (COADREAD), and kidney renal clear cell carcinoma (KIRC), and significantly downregulated in acute myeloid leukemia. And the results revealed good prognostic results for ERK, JNK, and P-38 MAPK in READ, COADREAD, and KIRC. We observed significant positive correlation between MAPK family gene expression and immune scores especially dendritic cells in READ, COADREAD, and KIRC. And we observed that the expression levels of MAPK family genes were significantly correlated with the expression of immune-related genes, such as CXCL1, CXCL2, CXCL8, CXCR1, CXCR2, CTLA-4, CD80, CD86, and CD28, suggesting their important role in regulating immune infiltrates and tumor progression. Therefore, our study suggested that MAPK family gene plays an important role in regulating immune infiltrates and tumor progression.

Abstract
BACKGROUND Thiamine responsive megaloblastic anemia (TRMA) is a genetic disease caused by SLC19A2 gene mutation. This study aimed to preliminarily explore the relationship between endoplasmic reticulum stress (ERS)-PERK signaling pathway and the pathogenesis of hyperglycemia induced by TRMA. METHODS Islet β (INS.1 and β-TC-6) and HEK293T cell line models with stable overexpression of SLC19A2 and SLC19A2 (c.1409insT) were established. The cells were divided into empty virus group (control), wild-type group (overexpressed SLC19A2), and mutation group (overexpressed SLC19A2 (c.1409insT)). Quantitative reverse transcription-polymerase chain reaction (RT-qPCR) and western blotting were used to detect the expression levels of ERS-PERK signaling pathway-related proteins, including glucose-regulated protein 78 (GRP78), protein kinase R-like ER kinase (PERK), and eukaryotic initiation factor 2 (eIF2α), activating transcription factor 4 (ATF4), and C/EBP homologous protein (CHOP) in islet β cells. Protein localization was assessed by immunofluorescence staining. RESULTS Compared with the control group, the mRNA expression levels of SLC19A2 in wild-type and mutant islet β cells (INS.1 and β-TC-6) and HEK293T cells were significantly upregulated (all p < 0.05). Compared with the control group and the wild-type group, the mRNA expression levels of GRP78, PERK, eIF2α, ATF4, and CHOP were increased (all p < 0.05) in the mutant islet β cells; the protein expression levels of PERK, GRP78, and eIF2α were elevated (all p < 0.05). In addition, the results of immunofluorescence staining showed that SLC19A2 (c.1409insT) mutation changed the localization of the proteins in the cells. Thus, they were not located on the cell surface, but in the cytoplasm and nuclei, and protein aggregation occurred in the cytoplasm. CONCLUSIONS 1. Islet β and HEK293Tcell lines, stably overexpressing SLC19A2 and SLC19A2 (c.1409insT) mutations, were successfully constructed. 2. SLC19A2 (c.1409insT) mutation could raise the expression levels of ERS-PERK signaling pathway-related proteins (GRP78, PERK, eIF2α, ATF4, and CHOP), and activate apoptosis pathway. 3. SLC19A2 (c.1409insT) mutation could change the localization of proteins and produce protein aggregation in cells. It could lead to protein misfolding and ERS, which would participate in the pathological mechanism of hyperglycemia induced by TRMA.

Abstract
Evidence from clinical studies and preclinical studies supports that exercise preconditioning can not only reduce the risk of stroke but also improve brain tissue and functional outcome after stroke. It has been demonstrated that autophagy and mitochondrial dynamics are involved in ischemic stroke. However, it is still unclear whether exercise preconditioning-induced neuroprotection against stroke is associated with modulation of autophagy and mitochondrial dynamics. Although age and sex interactively affect ischemic stroke risk, incidence, and outcome, studies based on young male animals are most often used to explore the role of exercise preconditioning in the prevention of ischemic stroke. In the current study, we examined whether exercise preconditioning could modulate autophagy and mitochondrial dynamics in a brain ischemia and reperfusion (I/R) model of female aged mice. The results showed that exercise preconditioning reduced infarct volume and improved neurological deficits. Additionally, increased levels of autophagy-related proteins LC3-II/LC3-I, LC3-II, p62, Atg7, and mitophagy-related proteins Bnip3L and Parkin, as well as increased levels of mitochondrial fusion modulator Mfn2 and mitochondrial fission modulator Drp1 in the ischemic cortex of female aged mice at 12 h after I/R were present. Our results could contribute to a better understanding of exercise preconditioning-induced neuroprotection against ischemic stroke for the elderly.

Abstract
OBJECTIVE To clarify the potential mechanism of Banxia Xiexin Decoction (BXD) on colorectal cancer (CRC) from the perspective of metabolomics. METHODS Forty male C57BL/6 mice were randomly divided into normal control (NC), azoxymethane/dextran sulfate sodium (AOM/DSS) model, low-dose BXD (L-BXD), high-dose BXD (H-BXD) and mesalamine (MS) groups according to a random number table, 8 mice in each group. Colorectal cancer model was induced by AOM/DSS. BXD was administered daily at doses of 3.915 (L-BXD) and 15.66 g/kg (H-BXD) by gavage for consecutive 21 days, and 100 mg/kg MS was used as positive control. Following the entire modeling cycle, colon length of mice was measured and quantity of colorectal tumors were counted. The spleen and thymus index were determined by calculating the spleen/thymus weight to body weight. Inflammatory cytokine and changes of serum metabolites were analyzed by enzyme-linked immunosorbent assay kits and ultra performance liquid chromatography-quadrupole/time-of-flight mass spectrometry (UPLC-Q/TOF-MS), respectively. RESULTS Notably, BXD supplementation protected against weight loss, mitigated tumor formation, and diminished histologic damage in mice treated with AOM/DSS (P<0.05 or P<0.01). Moreover, BXD suppressed expression of serum inflammatory enzymes, and improved the spleen and thymus index (P<0.05). Compared with the normal group, 102 kinds of differential metabolites were screened in the AOM/DSS group, including 48 potential biomarkers, involving 18 main metabolic pathways. Totally 18 potential biomarkers related to CRC were identified, and the anti-CRC mechanism of BXD was closely related to D-glutamine and D-glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, arginine biosynthesis, nitrogen metabolism and so on. CONCLUSION BXD exerts partial protective effects on AOM/DSS-induced CRC by reducing inflammation, protecting organism immunity ability, and regulating amino acid metabolism.

Abstract
To explore the application value of whole exome sequencing (WES) in the diagnosis of prenatal and postnatal neurodevelopmental disorders (NDDs). A total of 70 patients diagnosed with NDDs who underwent WES at the Medical Genetics Center of the Maternal and Child Health Hospital of Hubei Province between June 2020 and July 2021 were retrospectively analyzed. Genomic DNA was extracted from peripheral blood samples and amniotic fluid. WES-based copy number variant (CNV) analysis was integrated into the routine WES data analysis pipeline. The results showed that a molecular diagnosis rate could be made in 21/70 (30%) cases. Of 21 positive cases, 14 (23%) cases were detected by single-nucleotide variant/small insertion/deletion (SNV/Indel) analysis, of which 12 variants were novel, 6 (9.8%) cases were detected by WES-based CNV analysis, and 1 (1.6%) case was detected by a combination of both. The diagnostic yield of WES combined with CNV analysis was higher than that of SNV/Indel analysis alone (30%, 21/70 vs. 20%, 14/70). Of the 28 prenatally diagnosed cases, 6 cases were found to have inherited parental variation for NDDs, 10 cases were found not to have the same pathogenic variation as the proband, and the remaining 12 cases were found to have no pathogenic or likely pathogenic variation that could explain the NDDs phenotype. Clinical follow-up showed that 5 families opted for abortion and the remaining had no current abnormalities. In conclusion, WES may be an effective method to clarify the genetic etiology and prenatal diagnosis of NDDs, which is helpful in assessing the prognosis to aid clinical management and reproductive guidance.

Abstract
OBJECTIVE The aim of the work described here was to develop a non-invasive tool based on the radiomics and ultrasound features of automated breast volume scanning (ABVS), clinicopathological factors and serological indicators to evaluate axillary lymph node metastasis (ALNM) in patients with early invasive breast cancer (EIBC). METHODS We retrospectively analyzed 179 ABVS images of patients with EIBC at a single center from January 2016 to April 2022 and divided the patients into training and validation sets (ratio 8:2). Additionally, 97 ABVS images of patients with EIBC from a second center were enrolled as the test set. The radiomics signature was established with the least absolute shrinkage and selection operator. Significant ALNM predictors were screened using univariate logistic regression analysis and further combined to construct a nomogram using the multivariate logistic regression model. The receiver operating characteristic curve assessed the nomogram's predictive performance. DISCUSSION The constructed radiomics nomogram model, including ABVS radiomics signature, ultrasound assessment of axillary lymph node (ALN) status, convergence sign and erythrocyte distribution width (standard deviation), achieved moderate predictive performance for risk probability evaluation of ALNs in patients with EIBC. Compared with ultrasound, the nomogram model was able to provide a risk probability evaluation tool not only for the ALNs with positive ultrasound features but also for micrometastatic ALNs (generally without positive ultrasound features), which benefited from the radiomics analysis of multi-sourced data of patients with EIBC. CONCLUSION This ABVS-based radiomics nomogram model is a pre-operative, non-invasive and visualized tool that can help clinicians choose rational diagnostic and therapeutic protocols for ALNM.

Abstract
BACKGROUND AND PURPOSE Xin-Ji-Er-Kang (XJEK) is traditional Chinese formula presented excellent protective effects on several heart diseases, but the potential components and targets are still unclear. The aim of this study is to elucidate the effective components of XJEK and reveal its potential mechanism of cardioprotective effect in myocardial ischemia-reperfusion (MIR) injury. EXPERIMENTAL APPROACH Firstly, the key compounds in XJEK, plasma and heart tissue were analyzed by high resolution mass spectrometry. Bioinformatics studies were also involved to disclose the potential targets and the binding sites for the key compounds. Secondly, to study the protective effect of XJEK on MIR injury and related mechanism, mice subjected to MIR surgery and gavage administered with XJEK for 6 weeks. Cardiac function parameters and apoptosis level of cardiac tissue were assessed. The potential mechanism was further verified by knock down of target protein in vitro. RESULTS Pharmacokinetics studies showed that Sophora flavescens alkaloids, primarily composed with matrine, are the key component of XJEK. And, through bioinformatic analysis, we speculated JAK2 could be the potential target for XJEK, and could form stable hydrogen bonds with matrine. Administration of XJEK and matrine significantly improved heart function and reduced apoptosis of cardiomyocytes by increasing the phosphorylation of JAK2 and STAT3. The anti-apoptosis effect of XJEK and matrine was also observed on AC16 cells, and could be reversed by co-treatment with JAK2 inhibitor AG490 or knock-down of JAK2. CONCLUSION XJEK exerts cardioprotective effect on MIR injury, which may be associated with the activation of JAK2/STAT3 signaling pathway.

Abstract
Objective: To investigate the dynamic expression pattern of carcinoembryonic Wnt3a and its early monitoring value using a hepatocellular carcinoma model. Methods: Forty-eight Sprague Dawley (SD) rats were fed with pellet feed containing 2-acetylaminofluorene (2-AAF, 0.05%) to induce hepatocarcinogenesis, and control rats were fed a pellet diet. Liver tissue and blood samples were collected every two weeks. Liver tissues were pathologically examined using HE staining and grouped. The gene and Wnt3a mRNA expression were analyzed by genome-wide microarray. The expression and distribution of Wnt3a in liver tissue were analyzed by immunohistochemistry. Wnt3a concentration in liver tissue and serum was quantified by enzyme-linked immunosorbent assay. Statistical methods such as χ2 test, Mann-Whitney test and analysis of variance were used to analyze the differences between groups. Results: According to the pathological examination results, the rat livers were divided into four groups: control, hepatocyte degeneration, precancerous lesions and hepatocellular carcinoma. Genome-wide expression profiling analysis and comparison with the control group revealed that 268 and 312 genes were up-regulated and 57 and 201 genes were down-regulated in the precancerous and cancerous group when signal logarithm ratio (SLR) was >8 log2cy5/cy3, and these significantly altered genes mainly involved in cell proliferation, signal transduction, tumor metastasis, and apoptosis. The expression of Wnt3a at mRNA level was significantly increased in all stages of cancer induction, including degeneration group (1.15±0.24, q=8.227), precancerous group (1.85±0.18, q=12.361) and cancerous group (2.59±0.55, q=18.082). Compared with the control group (0.25±0.11, F=121.103, P<0.001), the degeneration group, the precancerous group and the liver cancer group were up-regulated by 4.6, 7.4 and 10.4-folds, respectively. Immunohistochemistry showed that compared with the control group, the positive rate of Wnt3a in the degeneration group was 66.7% (12/18, χ2=10.701, P=0.001), and both the precancerous and liver cancer groups were positive (9/9, χ2=17.115, P<0.001). Wnt3a expression was gradually increased in liver and blood samples during the process of carcinogenesis, and the difference between two groups was statistically significant (F=176.711, P<0.001). Wnt3a overexpression was secreted into blood stream via cancerous liver tissue, and there was a linear correlation between Wnt3a levels in blood and liver samples (r=0.732, P<0.001). Conclusions: Wnt3a overexpression is closely related with hepatocellular carcinogenesis, and thus may become a new monitoring marker.

Abstract
Background The mortality rate remains high among patients with coinfection with Pneumocystis pneumonia (PCP) and HIV. The timing for initiation of antiretroviral therapy (ART) after a diagnosis of moderate to severe PCP remains controversial, however. We therefore designed the present study to determine the optimal timing for ART initiation in AIDS-associated PCP (AIDS/PCP) patients.
Methods This was a multicenter, observational, prospective clinical trial. Eligible participants were recruited from 14 hospitals in mainland China, and assigned to an Early ART arm (initiation of ART ≤ 14 days after PCP diagnosis) and a Deferred ART arm (initiation of ART > 14 days after PCP diagnosis). The primary outcomes were death and the incidence of AIDS-defining events at week 48. The secondary outcomes were the changes in CD4+ T-cell counts from baseline values at weeks 12, 24, and 48, the virological suppression rate at week 24 and week 48, the rate of development of PCP-associated immune reconstitution inflammatory syndrome (PCP/IRIS), and the rate of adverse events over 48 weeks. Results The present study was performed using the data of 363 participants, with 169 participants in the Early ART arm, and 194 participants in the Deferred ART arm. Immunological and virological outcomes were found to be similar in both treatment arms. At week 48, there were no significant differences for the incidence of mortality (20 vs. 26, p = 0.860), and AIDS-defining events (17 vs. 26, p = 0.412). Over 48 weeks, the rates of PCP/IRIS (2 vs. 3, p = 1.000), adverse events (70 vs. 72, p = 0.465), and grade 3 or 4 adverse events (28 vs. 34, p = 0.919) did not reach statistical significance. A significant difference observed between two study arms was that 11 participants (55.0%) in the Early ART arm compared to 23 participants (88.5%) in the Deferred ART arm (p = 0.026) succumbed before ART had ever been started. Conclusions Early ART initiation results in no increase in mortality, AIDS-defining events, IRIS, adverse events, and immunological or virological outcomes. These results support the early initiation of ART in patients with moderate to severe AIDS/PCP. Clinical trial registration The present trial was registered at Chinese Clinical Trial Registry (ChiCTR1900021195). Registered 1 February 2019, http://www.chictr.org.cn/showproj.aspx?proj=35362.

Abstract
Background and Purpose: We have previously reported a cardioprotective effect with Xin-Ji-Er-Kang (XJEK) treatment in mice with myocardial infarction (MI)-induced heart failure, but no report about its potential functions in myocardial ischemia-reperfusion (MIR) injury. Here we studied the therapeutic effects of XJEK on MIR injury and investigated the mechanisms involved. Experimental Approach: MIR model of Balb/c mice induced by left anterior descending coronary artery ligation for half an hour, followed by reperfusion, was utilized to study the potential therapeutic effects of XJEK on MIR-induced cardiac injury. Ultra-performance liquid chromatography tandem Orbitrap mass spectrometry platform was used for studying serum lipid metabolic signatures. Key Results: MIR caused cardiac dysfunctions, cardiac injury, myocardial fibrosis, and increased inflammation, and all the observed abnormalities caused by MIR were largely corrected by XJEK treatment. Mechanistically, XJEK exerts its cardioprotective effect in the context of MIR injury by suppressing MIR-induced inflammation and dysregulation of serum lipid metabolism. Conclusion and Implications: We have demonstrated for the first time that XJEK protects heart from MIR injury by restoring dysregulated lipidomics. Our data provide new evidence to support a therapeutic effect for XIEK on MIR-induced cardiac injury, and pave the way for exploring the therapeutic potential of XJEK in large animal study and early clinical trial.

Abstract
Background: Emergence agitation (EA) is a common problem often observed in children after sevoflurane anesthesia, which can be prevented by dexmedetomidine and alfentanil. This study aims to compare the effectiveness of dexmedetomidine alone and with different doses of alfentanil in preventing EA in children under sevoflurane anesthesia. Materials and Methods: In a double-blind trial, 80 children (ASA I or II, 3-7 years old) undergoing tonsillectomy alone and adenotonsillectomy with sevoflurane anesthesia were randomly assigned into four groups: the control group, dexmedetomidine (DEX) group, dexmedetomidine plus 10 μg/kg alfentanil group (DEX + Alf1), and dexmedetomidine plus 20 μg/kg alfentanil group (DEX + ALf2). The incidence of EA was assessed with the Aono's scale, and the severity of EA was evaluated with the Pediatric Anesthesia Emergence Delirium (PAED) scale. The time of tracheal extubation and time of wake were recorded. Postoperative pain and complications such as nausea and vomiting, cough, laryngospasm, and bradycardia were recorded. Results: The incidence of EA was 50% in the control group, 25% in the DEX group, and 5% in the DEX + Alf1 group, and it never happened in the DEX + Alf2 group. The Aono's scale, the PAED scale, and the FLACC scale in the control group and the DEX group were significantly more than those in the DEX + Alf1 group and the DEX + Alf2 group after the tracheal extubation (p < 0.05). The time of tracheal extubation of the control group and the DEX group were significantly shorter than those in the DEX + Alf1 group and the DEX + Alf2 group (p < 0.05). The awakening time of the DEX + Alf2 group is significantly longer than those in other groups (p < 0.05). The case of postoperative nausea and vomiting in the DEX + Alf1 group was fewer than those in the other groups (p < 0.05). And, the cases of cough and laryngospasm and bronchospasm in the DEX + Alf1 group and the DEX + Alf2 group were significantly less than those in the control group and the DEX group after the tracheal extubation (p < 0.05). Conclusion: The combined administration of alfentanil and dexmedetomidine can reduce EA in children undergoing tonsillectomy alone and adenotonsillectomy with sevoflurane anesthesia. Dexmedetomidine plus 10 μg/kg alfentanil seems to be more appropriate than other dose combinations as it reduced EA and postoperative nausea and vomiting but did not prolong the time to awake.

Abstract
This study investigated the effects of tannic acid (TA)-treated corn on changes in ruminal fermentation characteristics and the composition of the ruminal bacterial community in vitro. Ruminal fluid was obtained from three rumen-fistulated goats fed a 60:40 (forage/concentrate) diet. The batch cultures consisted of 25 ml of strained rumen fluid in 25 ml of an anaerobic buffer containing 0.56 g of ground corn, 0.24 g of soybean meal, 0.10 g of alfalfa, and 0.10 g of oat grass. Ground corn (2 mm) was steeped in an equal quantity (i.e., in a ratio of 1:1, w/v) of water alone (Con), 15 (TA15), 25 (TA25), and 35 g/l (TA35) TA solution for 12 h. After incubation for 24 h, TA-treated corn linearly increased (P <0.05) ruminal pH and the molar proportion of acetate, but linearly reduced (P <0.05) total volatile fatty acids and the molar proportion of butyrate compared with the Con treatment. Illumina MiSeq sequencing was used to investigate the profile changes of the ruminal microbes. A principal coordinates analysis plot based on weighted UniFrac values revealed that the structure of the ruminal bacterial communities in the control group was different from that of the TA-treated corn groups. The results of changes in the rumen bacterial communities showed that TA-treated corn linearly enriched (P <0.05) Rikenellaceae_RC9_gut_group, but linearly reduced (P <0.05) Ruminococcaceae_NK4A214_group, Ruminococcus_2, and unclassified_o__Clostridiales. Functional prediction of ruminal microbiota revealed that the TA-treated corn linearly decreased ruminal microbiota function of utilizing starch through pyruvate metabolism. In conclusion, TA-treated corn can modulate the rumen fermentation characteristics, microbial composition, and metabolic pathways, which may be potentially useful for preventing the occurrence of ruminal acidosis.

Abstract
BACKGROUND The effectiveness of adjunctive corticosteroid use in patients with coronavirus disease 2019 (COVID-19) remains inconclusive.
AIM To investigate the effectiveness of adjunctive corticosteroid therapy in patients with severe COVID-19.
METHODS We conducted a retrospective analysis of the difference in several outcomes between patients with severe COVID-19 who received corticosteroid therapy (the corticosteroid group) and patients with severe COVID-19 who did not receive corticosteroid therapy (the non-corticosteroid group).
RESULTS Seventy-five patients were included in this study. Of these, 47 patients were in the corticosteroid group and 28 patients were in the non-corticosteroid group. There were no differences between the two groups in the total length of hospital stay, the length of intensive care unit stay, high-flow oxygen days, non-invasive ventilator days, invasive ventilation days, and mortality rate. Total lesion volume ratio, consolidation volume ratio and ground-glass opacity volume ratio in the corticosteroid group decreased significantly on day 14, while those in the non-corticosteroid group did not show a significant decrease.
CONCLUSION Our results show that adjunctive corticosteroid use did not significantly improve clinical outcomes in severe COVID-19 patients, but might promote the absorption of pulmonary lesions. Larger multicenter randomized controlled studies may be needed to confirm this.

Abstract
Background Cytomegalovirus retinitis (CMVR) is an important opportunistic infection (OI) occurring mainly in patients with acquired immunodeficiency syndrome (AIDS) and has the potential to cause severe visual impairment and blindness among AIDS patients. Subsequent to the adoption and implementation of widespread antiretroviral therapy (ART), the prognosis of AIDS-associated CMVR has been substantially improved. Nevertheless, the equivocal clinical evidence as regards the optimal timing for ART initiation in patients with an established CMVR diagnosis is required. We therefore designed the present study in order to investigate the optimal timing for ART initiation in AIDS/CMVR patients. Methods This will be a prospective, randomized controlled trial to be performed at 17 hospitals in mainland China. A total of 300 participants with CMVR will be randomly assigned to an early ART initiation group (ART initiation within 2 weeks after anti-CMV therapy), or a deferred ART initiation group (initiation of ART more than 2 weeks after anti-CMV therapy) at a 1:1 ratio. All participants will receive 48 weeks of follow-up after anti-CMV therapy initiation. Our primary outcome will be the incidence of visual loss (to a visual acuity worse than 20/40 or 20/200) in the two groups during the 48-week follow-up period. Secondary outcomes will include changes in HIV virological suppression and serum CD4+ T-cell counts, the incidence of mortality, retinitis progression (movement of the peripheral border of a CMV lesion ≥ ½ disc diameter, or occurrence of a new CMV lesion), retinal detachment, immune recovery uveitis (IRU), and other OIs and adverse events between the two study groups during the 48 weeks of follow-up. Discussion The study aims to investigate the optimal timing for ART initiation in AIDS/CMVR patients. We hope to be able to extract robust clinical evidence for use in optimal AIDS/CMVR management should our trial be successful. Trial registration This research was registered as one of the twelve clinical trials under the name of a general project “A study for precision diagnosing and treatment strategies in difficult-to-treat AIDS cases and HIV-infected patients with highly fatal or highly disabling opportunistic infections”, ChiCTR1900021195.

Abstract
Aim Early diagnosis and treatment are crucial for the survival of severe Coronavirus Disease 2019 (COVID-19) patients, but data with regard to risk factors for disease progression from milder COVID-19 to severe COVID-19 remain scarce. Methods We conducted a retrospective analysis on 116 patients. Results Three factors were observed to be independently associated with progression to severe COVID-19 during 14 days after admission: (a) age 65 years or older (hazard ratio [HR] = 8.456; 95% CI: 2.706–26.426); (b) creatine kinase (CK) ≥ 180 U/L (HR = 3.667; 95% CI: 1.253–10.733); and (c) CD4+ T-cell counts <300 cells/µL (HR = 4.695; 95% CI: 1.483–14.856). The difference in rates of severe COVID-19 development was found to be statistically significant between patients aged 65 years or older (46.2%) and those younger than 65 years (90.2%), between patients with CK ≥ 180 U/L (55.6%) and those with CK < 180 U/L (91.5%), and between patients with CD4+ T-cell counts <300 cells/µL (53.8%) and those with CD4+ cell counts ≥300 cells/µL (83.2%). Conclusions Age ≥ 65 years, CK ≥ 180 U/L, and CD4+ T-cell counts <300 cells/µL at admission were risk factors independently associated with disease progression to severe COVID-19 during 14 days after admission and are therefore potential markers for disease progression in patients with milder COVID-19.

Abstract
Objective: To explore whether combining treatment of chronic obstructive pulmonary disease (COPD) with anti-tumor therapy is better than that of tumor treatment alone in advanced non-small cell lung cancer (NSCLC) patients with COPD in the real world. Methods: The clinical data of 101 patients with advanced NSCLC complicated with COPD from January 1, 2015, to December 31, 2017, in the First Affiliated Hospital of Guangzhou Medical University were analyzed retrospectively, including 99 males and two females, aged from 52 to 84 years[average (67±8) years]. Among the patients, 90 (89.1%) were smokers, with an average pack-year smoking index of (47±4) . The patients were divided into observation and control groups, depending on whether they received standardized anti-COPD supportive treatment. In the observation group, there were 36 patients, including 35 males and one female, aged from 54 to 84 years[ average (67±8) years], with an average pack-year of smoking (47±4). There were 65 patients in the control group, including 64 males and one female, aged from 52 to 83 years [average (67±8) years], with an average pack-year of smoking 47±4. There was no significant difference in the baseline data between the two groups. The primary outcome measures included the Objective response rate (ORR), disease control rate (DCR), disease-free survival (PFS), and overall survival (OS) of the two groups. An unpaired t-test was used to compare continuous variables between the observation and control groups. The Pearson chi-square test was used to compare categorical variables between the two groups. Kaplan-Meier survival curves were used to evaluate the median PFS and median OS of patients, and the log-rank test was used to assess differences between groups. Result: The ORR of the observation group and the control group was 22.6% (7 cases) and 22.2% (11 cases), respectively, with no significant difference (χ(2)=0.01, P=0.971). The DCR between the observation group and the control group was 58.1% (19 cases) and 57.8% (27 cases), with no significant difference (χ(2)=0.02, P=0.889). Median PFS in the observation group was 6.0 months, which was better than the 3.5 months in the control group (χ(2)=3.947, P<0.05). The median OS of the observation group was 18.0 months, which was better than the 15.0 months of the control group (χ(2)=4.083, P<0.05). Conclusions: Compared with the treatment of tumors alone, combination of anti-tumor therapy with anti-COPD therapy showed longer PFS and OS in patients with advanced NSCLC complicated with COPD.

Abstract
BACKGROUND At the end of 2019, a novel coronavirus outbreak causative organism has been subsequently designated the 2019 novel coronavirus (2019-nCoV). The effectiveness of adjunctive glucocorticoid therapy in the management of 2019-nCoV-infected patients with severe lower respiratory tract infections is not clear, and warrants further investigation. METHODS The present study will be conducted as an open-labeled, randomized, controlled trial. We will enrol 48 subjects from Chongqing Public Health Medical Center. Each eligible subject will be assigned to an intervention group (methylprednisolone via intravenous injection at a dose of 1-2 mg/kg/day for 3 days) or a control group (no glucocorticoid use) randomly, at a 1:1 ratio. Subjects in both groups will be invited for 28 days of follow-up which will be scheduled at four consecutive visit points. We will use the clinical improvement rate as our primary endpoint. Secondary endpoints include the timing of clinical improvement after intervention, duration of mechanical ventilation, duration of hospitalization, overall incidence of adverse events, as well as rate of adverse events at each visit, and mortality at 2 and 4 weeks. DISCUSSION The present coronavirus outbreak is the third serious global coronavirus outbreak in the past two decades. Oral and parenteral glucocorticoids have been used in the management of severe respiratory symptoms in coronavirus-infected patients in the past. However, there remains no definitive evidence in the literature for or against the utilization of systemic glucocorticoids in seriously ill patients with coronavirus-related severe respiratory disease, or indeed in other types of severe respiratory disease. In this study, we hope to discover evidence either supporting or opposing the systemic therapeutic administration of glucocorticoids in patients with severe coronavirus disease 2019.

Abstract
BACKGROUND An increased frequency of toxoplasma encephalitis, caused by Toxoplasma gondii, has been reported in AIDS patients, especially in those with CD4+ T cell counts <100 cells/μL. Several guidelines recommend the combination of pyrimethamine, sulfadiazine, and leucovorin as the preferred regimen for AIDS-associated toxoplasma encephalitis. However, it is not commonly used in China due to limited access to pyrimethamine and sulfadiazine. The synergistic sulfonamides tablet formulation is a combination of trimethoprim (TMP), sulfadiazine and sulfamethoxazole (SMX), and is readily available in China. Considering its constituent components, we hypothesize that this drug may be used as a substitute for sulfadiazine and TMP-SMX. We have therefore designed the present trial, and propose to investigate the efficacy and safety of synergistic sulfonamides combined with clindamycin for the treatment of toxoplasma encephalitis. METHODS/DESIGN This study will be an open-labeled, multi-center, prospective, randomized, and controlled trial. A total of 200 patients will be randomized into TMP-SMX plus azithromycin group, and synergistic sulfonamides plus clindamycin group at a ratio of 1:1. All participants will be invited to participate in a 48-week follow-up schedule once enrolled. The primary outcomes will be clinical response rate and all-cause mortality at 12 weeks. The secondary outcomes will be clinical response rate and all-cause mortality at 48 weeks, and adverse events at each visit during the follow-up period. DISCUSSION We hope that the results of this study will be able to provide reliable evidence for the efficacy and safety of synergistic sulfonamides for its use in AIDS patients with toxoplasma encephalitis. TRIAL REGISTRATION This study was registered as one of 12 clinical trials under the name of a general project at chictr.gov on February 1, 2019, and the registration number of the general project is ChiCTR1900021195. This study is still recruiting now, and the first patient was screened on March 22, 2019.

Abstract
Breast cancer resistance protein (BCRP) is one of ATP-binding cassette (ABC) transporters in brain microvessel endothelial cells that transport their substrates from brain to blood, thus limiting substrates to crossing into brain through blood-brain barrier. Our previous works show that bile duct ligation (BDL) impairs expression and function of brain BCRP in rats. Since zidovudine (AZT) is BCRP substrate, we investigated whether impaired expression and function of BCRP increased brain distribution and toxicity of AZT in BDL-D7 rats. After administration of AZT (10 mg/kg, i.v.), BDL markedly increased brain AZT concentrations, compared with sham-operated (SO) rats. The ratio of AZT brain-to-plasma area under concentration curve (AUC) in BDL rats was increased to 1.6-folds of SO rats. After treatment with AZT (100 mg/kg every day, i.v.) for 7 days, BDL significantly impaired cognitive functions compared with SO rats, evidenced by the significantly decreased percentage of alternation in Y-maze test and prolonged escaped latency in two-way passive avoidance trial. Furthermore, AZT treatment caused significant decrease in copies of mitochondrial DNA and mitochondrial membrane potential in hippocampus of BDL rats. Moreover, AZT treatment caused a significant decrease of cortex microtubule-associated protein 2 and hippocampus synaptophysin levels in BDL rats. AZT-induced CNS adverse alterations in BDL rats were not observed in SO rats treated with AZT. In conclusion, BDL decreases the function and expression of brain BCRP in rats, leading to increased brain distribution of AZT, which in turn enhances AZT CNS toxicity, leading to mitochondrial dysfunction, neuronal damage, and ultimately cognitive dysfunction.

Abstract
Purpose For the diagnosis of nasopharyngeal carcinoma (NPC), reliable early indicators with sensitivity and specificity should be sought. This study evaluated the effect of the combined use of mean platelet volume/platelet count ratio (MPV/PC ratio) and platelet distribution width (PDW) for differential diagnosis of NPC. In this study, MPV/PC ratio was used for the first time to diagnostically evaluate NPC. Patients and methods We retrospectively analyzed various hematological indices of three subject groups (208, 185, and 162 patients with NPC, benign tumors of the nasopharynx, and healthy subjects, respectively) and evaluated the value of combined use of MPV/PC ratio and PDW for differential diagnosis of the three groups using the one-way analysis of variance. Results Comparison of laboratory variables between the three groups showed a significant difference in MPV/PC ratio and PDW (P<0.001, all). The MPV/PC ratio in the NPC group was significantly lower than the other two groups (P<0.001); MPV/PC ratio also showed a statistically significant difference in different stages (P=0.034) and serosal invasions (P<0.001) of the NPC group. Receiver operating characteristic curve (ROC) analysis showed that areas under the curve (AUC) of either patients with benign tumors of the nasopharynx (AUCMPV/PCratio+PDW: 0.708) or healthy subjects (AUCMPV/PCratio+PDW: 0.909) were larger than those of MPV/PC ratio (AUCMPV/PCratio: 0.665, 0.869, respectively) and PDW (AUCPDW:0.614, 0.716, respectively) use alone (P<0.05, all). Conclusion MPV/PC ratio and PDW may be used as indexes of NPC. MPV/PC ratio combined with PDW could be considered as meaningful laboratory indexes for differential diagnosis of NPC, benign tumors of the nasopharynx, and healthy subjects. This finding could enhance the detection of NPC.

Abstract
Autophagy has been reported to play protective and pathogenetic roles in cerebral ischemia/reperfusion (I/R)-induced neuronal injury. Our previous studies have shown that TP53-induced glycolysis and apoptosis regulator (TIGAR) ameliorates I/R-induced brain injury and reduces anti-cancer drug-induced autophagy activation. However, if TIGAR plays a regulatory role on autophagy in cerebral I/R injury is still unclear. The purpose of the present study is to investigate the role of TIGAR on I/R-induced autophagy activation and ischemic neuronal injury in vivo and in vitro stroke models using TIGAR-transgenic (tg-TIGAR) mice and TIGAR-knockout (ko-TIGAR) mice. The present study confirmed that autophagy was activated after I/R. Overexpression of TIGAR in tg-TIGAR mice significantly reduced I/R-induced autophagy activation and alleviated brain damage, while knockout of TIGAR in ko-TIGAR mice enhanced I/R-induced autophagy activation and exacerbated brain injury in vivo and in vitro. The different activity of autophagy in tg-TIGAR and ko-TIGAR primary neurons after OGD/R were largely reversed by knockdown or re-expression of TIGAR in these neurons. The autophagy inhibitor 3-methyladenine (3-MA) partly prevented exacerbation of brain damage induced by ko-TIGAR, whereas the autophagy inducer rapamycin partially abolished the neuroprotective effect of tg-TIGAR. Knockout of TIGAR reduced the levels of phosphorylated mTOR and S6KP70, which were blocked by 3-MA and NADPH after I/R and OGD/R in vivo and in vitro, respectively. Overexpression of TIGAR increased the levels of phosphorylated mTOR and S6KP70 under OGD/R condition, this enhancement effect was suppressed by rapamycin. In conclusion, our current data suggest that TIGAR protected against neuronal injury partly through inhibiting autophagy by regulating the mTOR-S6KP70 signaling pathway.

Abstract
BACKGROUND Mean platelet volume (MPV) is a marker of platelet activation. MPV and platelet count (PC) are negatively correlated, and their ratio (MPV/PC) is informative for the diagnosis of malignant tumors. However, the relationship between MPV/PC and colorectal cancer is unclear. This retrospective clinical study aimed to evaluate the diagnostic value of MPV/PC in colorectal cancer. METHODS Hematological examinations were performed at initial diagnosis in patients with colorectal cancer (n = 186) or adenomatous polyp (n = 132) and healthy controls (n = 108). Hematological parameters evaluated included white blood cells, red blood cells, hemoglobin, neutrophils, lymphocytes, monocytes, PC, and MPV. Statistical analyses included Student's t-test, one-way ANOVA or Kruskal-Wallis H test, chi-square tests, Spearman's correlation test and receiver operating characteristic (ROC). ROC curve was used to evaluate the diagnostic values of MPV and MPV/PC in colorectal cancer. RESULTS Among these groups, MPV was significantly lower in colorectal cancer than in adenomatous polyp (p = 0.002) and healthy controls (p < 0.001) but did not significantly differ between adenomatous polyp and healthy controls (p = 0.210). MPV/PC was lower in colorectal cancer compared with adenomatous polyp and healthy controls (p < 0.001) and in adenomatous polyp compared with healthy controls (p = 0.010). MPV did not significantly differ among colorectal cancer subgroups, while MPV/PC significantly differed between TNM stages and the presence/absence of lymph node metastasis. MPV/PC was negatively correlated with the neutrophil to lymphocyte ratio(NLR) (p = 0.002) and platelet to lymphocyte ratio(PLR) concentration (p < 0.001). In the differential diagnosis between colorectal cancer and adenomatous polyp, MPV/PC produced a larger ROC curve than MPV, NLR or PLR alone. Using MPV/PC to distinguish between colorectal cancer and controls produced a larger AUC than using MPV or NLR alone. CONCLUSIONS MPV/PC may be useful for the diagnosis of colorectal cancer. However, further studies are warranted to include additional regions and more data, to assess the utility of MPV/PC as a novel diagnostic screening tool for colorectal cancer.

Abstract
Background Inflammation plays an important role in the occurrence and development of cancer. Numerous studies have used the derived neutrophil‐to‐lymphocyte ratio (dNLR) to evaluate prognosis in many types of cancer. However, the relationship between dNLR and ovarian cancer and its value in the differential diagnosis of benign and malignant ovarian tumors remain unknown. Methods A total of 262 patients with ovarian cancer, 258 with benign ovarian disease, and 232 healthy controls were included in this study. dNLR was calculated using whole blood cell parameters. Receiver operating characteristic curves were generated to obtain sensitivity, specificity, and area under the ROC curve (AUC) to evaluate the diagnostic values of dNLR. Results dNLR was significantly different among the ovarian cancer, benign ovarian disease, and healthy control groups (all P < 0.001). Moreover, there were significant differences in dNLR between patients with early‐stage (I and II) and advanced‐stage (III and IV) disease (P < 0.001). dNLR was positively correlated with stage and carbohydrate antigen‐125 in ovarian cancer. A cutoff value of dNLR ≤2.11 was diagnostic in distinguishing ovarian cancer from benign ovarian disease with AUC of 0.729 (95% confidence interval [CI], 0.689‐0.767; P = 0.0001). A cutoff value of dNLR ≤1.9 was diagnostic in distinguishing ovarian cancer from healthy controls with an AUC of 0.821 (95% CI, 0.784‐0.854; P = 0.0001). Conclusion dNLR may be a useful indicator for distinguishing between ovarian cancer and benign ovarian disease and for identifying early and advanced ovarian cancer.

Abstract
Gliomas are the most prevalent type of primary brain tumors in adults, accounting for more than 40% of neoplasms in the central nervous system. The spen paralogue and orthologue C-terminal domain containing 1 (SPOCD1) has been recently identified and found to discriminate progressive from non-progressive bladder cancers. In this study, we detected high-level of SPOCD1 expression in glioma and its high expression significantly associated with advanced tumor grade and poor prognosis. In vitro assays showed that knockdown of SPOCD1 significantly inhibited cell proliferation and colony formation capacities in U373 and U87 cells. In a xenograft model of glioma, SPOCD1 was also found to inhibit tumor growth. In addition, knockdown of SPOCD1 was shown to inhibit cell migration and invasion in glioma U373 and U87 cells. SPOCD1 positively regulated the expression of Pentraxin 3 (PTX3), whereas overexpression of PTX3 attenuated SPOCD1 knockdown-mediated inhibition of cell proliferation, migration and invasion in glioma cells. Our observations suggest that SPOCD1 promotes the proliferation and metastasis of glioma cells through regulating PTX3. Our data might provide novel evidence for the diagnosis and treatment of glioma in clinic.

Abstract
BACKGROUND Severe hypertriglyceridemia usually results from a combination of genetic and environmental factors and is most often attributable to mutations in the lipoprotein lipase (LPL) gene. OBJECTIVES The aim of this study was to identify rare mutations in the LPL gene causing severe hypertriglyceridemia. METHODS A Chinese infant who presented classical features of severe hypertriglyceridemia recruited for DNA sequencing of the LPL gene. The pathogenicity grade of the variants was defined based on the prediction of pathogenicity using in silico prediction tools. Review some studies to understand the molecular mechanisms underlying the severe hypertriglyceridemia. RESULTS We identified a rare mutation in the LPL gene causing severe hypertriglyceridemia: a nucleotide substitution (c.836T>G) resulting in a leucine to arginine substitution at position 279 of the protein (p.Leu279Arg).The pathogenicity of the variant was predicted by in silico analysis using PolyPhen2 and SIFT prediction programs, which indicated that mutation p.Leu279Arg is probably harmful. We have also reviewed published studies concerning the molecular mechanisms underlying severe hypertriglyceridemia. A missense mutation in the 6 exon of the LPL gene is reportedly associated with LPL deficiency. CONCLUSIONS We have here identified a rare pathogenic mutation in the LPL gene in a Chinese infant with severe hypertriglyceridemia.

Abstract
Objective: To analyze the treatment of advanced non-small cell lung cancer (NSCLC) with performance status (PS) scores between 2 and 4, in order to improve the diagnosis and treatment of these patients. Methods: A total of 36 patients with advanced NSCLC with hypoxemia were reviewed. The clinical data of disease characteristics, etiology, complications, manifestation, therapy, progression, and secondary biopsy were collected. The clinical efficacy was graded according to the Response Evaluation Criteria In Solid Tumors (RECIST): complete response (CR), partial response (PR), stable disease (SD) and disease progression (PD). Results: All patients had hypoxemia, of whom 86.1% (31 patients) had complications and 55.6% (20 patients) had noninvasive ventilator for respiratory support. 77.8% (28 cases) received broad-spectrum antibiotic treatment, and 78.6% of them got lung osmotic relief after the anti-infection treatment. 15 cases received bedside fiberoptic bronchoscopy suction, of whom two cases were treated with airway stent deposition due to airway obstruction, four cases with thoracic drainage, four cases with anticoagulation, and one with thrombolytic therapy. After these supportive treatment, the PS score of these patients decreased from 3.4±0.5 to 2.5±0.7, while SPO(2) improved from (89.0±5.2)% to (95.0±3.5)%. As first-ling anti-cancer treatment, nine patients were administrated with targeted medicine orally, 13 patients with a combined chemotherapy of pemetrexed plus bevacizumab or carboplatin, eight patients with paclitaxel plus carboplatin, four patients with gemcitabine plus carboplatin, and two patients with docetaxel plus gemcitabine. In the first response evaluation, there were one case of CR, 23 cases of PR, four cases of SD, and eight cases of PD, with a clinical benefit rate of 66.7% and a disease control rate of 77.8%. A total of 22 patients experienced disease progression, of whom eight cases had a secondary biopsy and six cases had gene sequencing. Of these 36 patients, 10 (27.8%) patients survived at the last follow-up, with a progression-free survival of (10.0±6.5) months. Conclusion: Besides prompt anti-cancer treatment and best supportive treatment should be incorporated to improve PS and improve outcome.

Abstract
TIGAR-regulated pentose phosphate pathway (PPP) plays a critical role in the neuronal survival during cerebral ischemia/reperfusion. Glucose-6-phosphate dehydrogenase (G6PD) is a rate-limiting enzyme in PPP and thus, we hypothesized that it plays an essential role in anti-oxidative defense through producing NADPH. The present study investigated the regulation and the role of G6PD in ischemia/reperfusion-induced neuronal injury with in vivo and in vitro models of ischemic stroke. The results showed that the levels of G6PD mRNA and protein were increased after ischemia/reperfusion. In vivo, lentivirus-mediated G6PD overexpression in mice markedly reduced neuronal damage after ischemia/reperfusion insult, while lentivirus-mediated G6PD knockdown exacerbated it. In vitro, overexpression of G6PD in cultured primary neurons decreased neuronal injury under oxygen and glucose deprivation/reoxygenation (OGD/R) condition, whereas knockdown of G6PD aggravated it. Overexpression of G6PD increased levels of NADPH and reduced form of glutathione (rGSH), and ameliorated ROS-induced macromolecular damage. On the contrary, knockdown of G6PD executed the opposite effects in mice and in primary neurons. Supplementation of exogenous NADPH alleviated the detrimental effects of G6PD knockdown, whereas further enhanced the beneficial effects of G6PD overexpression in ischemic injury. Therefore, our results suggest that G6PD protects ischemic brain injury through increasing PPP. Thus G6PD may be considered as potential therapeutic target for treatment of ischemic brain injury.

Abstract
BACKGROUND Studies on homocysteine (Hcy) have mainly focused on the correlation between the homocysteine concentration and disease development. Few epidemiological investigations have been performed. This study was conducted to investigate the prevalence of hyperhomocysteinemia (HHcy) during routine physical examination in Guangxi Province, China and the correlation of serum Hcy with gender, age, serum uric acid (UA), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and blood glucose (GLU) to provide evidence for preventing and treating HHcy. METHODS Data of 8043 patients who underwent physical examinations at the First Affiliated Hospital of Guangxi Medical University, China from 2015 to 2016 were collected. These data included gender, age, and the serum Hcy, UA, GLU, TC, TG, HDL-C, and LDL-C concentrations. RESULTS The overall prevalence of HHcy was 50.8% (52.3% in males, 48.1% in females). Age, UA, TC, TG, and LDL-C were significantly higher and HDL-C was significantly lower in patients with than without HHcy, regardless of gender (all P<.05). The Hcy level was positively correlated with UA, TC, TG, and LDL-C but negatively correlated with HDL-C. Gender, age, UA, TC, and TG were independent risk factors for HHcy. CONCLUSION The prevalence of HHcy was very high during routine physical examination in Guangxi Province, China. HHcy was related to gender, age, high concentrations of UA, TC, TG, and LDL-C; and low concentrations of HDL-C. Strengthening early intervention of HHcy can reduce the risk of cardiovascular disease.

Abstract
OBJECTIVE To isolate platelet-rich plasma(PRP) from the white slurry(WS), a depleted fraction of the clinical blood supply, so as to provide an easier method to harvest PRP for related studies and clinical use. METHODS The protocols preparing PRP from whole blood and WS were compared. The morphological characteristics of the different PRPs were observed under transmission electron microscope; the expression of the platelet markers CD41a and CD42b were detected by the flow cytometry. Moreover, the ingredients of the PRPs were measured by using cytoanalyzer. for detecting the physiological function of the PRP, the harvested PRP were added to MSC culture and the cell proliferation was detected by using CCK-8 method. RESULTS a large amount of PRP from WS was easier harvested. the WS-derived PRP shared similar morphological characteristics and ingredients as compared with whole blood-derived PRP. Importantly, the WS-derived PRP exhibited a higher expression of CD41a and CD42b than that of traditional PRP, which indicate that the WS is a promising reservoir for PRP. CONCLUSION The WS can be used to prepare PRP, and the novel PRP share similar biological characteristics as traditional PRP prepared from whole blood. The present study provides an easier and economical method to harvest PRP and this findings may be helpful for PRP related studies.

Abstract
Our previous study has reported that the pentose phosphate pathway product nicotinamide adenine dinucleotide phosphate (NADPH) protected neurons against ischemia/reperfusion-induced brain injury. NADPH can either act as a co-enzyme to produce GSH or a substrate of NADPH oxidase (NOX) to generate ROS. This study was designed to elucidate the effects of co-treatment with NADPH and NOX inhibitor apocynin on ischemia/reperfusion-induced brain inflammation and neuronal injury. The results showed that both NADPH and apocynin markedly attenuated ischemia/reperfusion-induced increases in the levels of NOX2, NOX4 and ROS. NADPH and apocynin significantly inhibited the phosphorylation and degradation of IκBα, NF-κBp65 nuclear localization, and the expression of NF-κB target gene cyclooxygenase (COX2) and inducible nitric oxide synthase (iNOS). Furthermore, both NADPH and apocynin suppressed the expression of inflammasome proteins including NLRP3 ASC, caspase-1, interleukin (IL)-1β and IL-18 in the ischemic cortex as revealed by Western blot analysis and immunofluorescence. Moreover, all these effects were greatly amplified by combination of NADPH and apocynin. Both NADPH and apocynin significantly reduced infarct volume, improved post-stroke survival, and recovery of neurological functions in mouse model of stroke. Consistently, the combination of NADPH and apocynin produced greater beneficial effects in against ischemic brain damage. These studies suggest that, beyond anti-oxidative effects, NADPH may also have anti-inflammatory effects and combination of NADPH and NOX inhibitors could produce a greater neuroprotective effect in ischemic stroke.

Abstract
OBJECTIVE To investigate the impact of previous cystectomy for ovary benign cyst on ovarian reserve and pregnancy outcome in in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. METHODS Totally 622 infertility patients were retrospectively investigated who underwent first IVF/ICSI-ET cycle in Reproductive Hospital Affiliated to Shandong University from January 2013 to June 2014. There were 153 cases who had been removed ovarian cyst by cystectomy surgeries recruited as study group, in which 44 cases of ovarian endometriosis cyst, 35 cases of benign ovarian teratomas, 67 cases of simple ovarian cyst and 7 cases of ovarian mucinous cystadenoma. In contrast, 469 infertility patients with tubal-factor infertility or male factor were included as control group. The age-matched women in the control group had no ovarian surgery previously. The indicators of ovarian reserve and pregnancy outcome were analyzed between two groups. The influence of different types of ovarian cysts on ovarian reserve and pregnancy outcome in IVF/ICSI-ET cycles were also studied, ovarian endometriosis cyst was studied as Group A, and Group B consisted of benign ovarian teratomas, simple ovarian cyst and mucinous cystadenoma. RESULTS (1) The significantly lower serum antimullerian hormone (AMH) level (median: 1.92 versus 2.90 mg/L), antral follicle count (AFC; median: 12.0 versus 13.0), retrieved oocytes (12±5 versus 13±6) and the number of embryo cryopreserved (median: 1.0 versus 3.0) were found in study group compared with control group (all P<0.05). There was no statistical difference between two group for the following parameters, such as basal FSH level, the total dosage of gonadotropin duration and the total dosage of gonadotropin (all P>0.05). A better clinical pregnancy rate was achieved in control group (61.6%, 241/391) than that in study group (61.4%, 81/132), but no significant difference was existed (P=0.96). (2) Compared to Group B, Group A had fewer AFC, lower serum AMH level, retrieved oocytes and the number of embryo cryopreserved (11±4 versus 13±5; 1.65 versus 2.15 mg/L; 9±4 versus 13±5; 0 versus 2.0; all P< 0.01). There was a lower clinical pregnancy rate in Group A than that in Group B [50.0% (19/38) versus 66.0% (62/94)], accompanying with higher abortion rate [3/19 versus 9.7% (6/62)], but no differences were observed (all P>0.05). CONCLUSIONS Ovarian reserve declines after the cystectomy for ovarian benign cysts and the cystectomy has a negative impact on IVF/ICSI-ET cycle, resulting in a decrease of the number of retrieved oocytes and the number of embryo cryopreserved, but do not influence clinical pregnancy outcome. Ovarian reserve is impaired more seriously by cystectomy for ovarian endometriosis cyst than other ovarian benign cyst.

Abstract
BACKGROUND AND PURPOSE Our previous study has defined a role of TP53-induced glycolysis and apoptosis regulator in neuroprotection against ischemic injury through increasing the flow of pentose phosphate pathway. We hypothesized that the pentose phosphate pathway product nicotinamide adenine dinucleotide phosphate (NADPH) could be a novel drug for treatment of ischemic stroke. METHODS The NADPH was given before, at the onset, or after stroke onset with single or repeated intravenous (mice and rats) or intraperitoneal injections (monkey). The short- and long-term therapeutic effects of NADPH were evaluated in male adult ICR mice (total=614) with transient middle cerebral artery occlusion, in male adult Sprague-Dawley rats (total=114) with permanent middle cerebral artery occlusion, and in male adult rhesus monkey (total=12) with thrombotic middle cerebral artery occlusion. RESULTS Administration of NADPH led to a dramatic increase in the levels of ATP and reduced form of glutathione, whereas it decreased the levels of reactive oxygen species. NADPH significantly reduced infarct volume, improved poststroke survival, and recovery of neurological functions in mouse and rat models of stroke. Robust neuroprotection of a single dose of NADPH was seen when it was administered within 5 hours after reperfusion; however, repeat administration of NADPH twice a day for 7 days starting 24 hours after the onset of stroke also offered therapeutic effects. Pretreatment with NADPH also significantly improved the outcome of stroke insult. CONCLUSIONS Administration of exogenous NADPH significantly protected neurons against ischemia/reperfusion-induced injury in 2 rodent stroke models. Thus, NADPH might be a promising drug candidate for treatment of ischemic stroke.

Abstract
BACKGROUND Previous studies have indicated that the cognitive deficits in patients with Alzheimer's disease (AD) may be due to topological deteriorations of the brain network. However, whether the selection of a specific frequency band could impact the topological properties is still not clear. Our hypothesis is that the topological properties of AD patients are also frequency-specific. METHODS Resting state functional magnetic resonance imaging data from 10 right-handed moderate AD patients (mean age: 64.3 years; mean mini mental state examination [MMSE]: 18.0) and 10 age and gender-matched healthy controls (mean age: 63.6 years; mean MMSE: 28.2) were enrolled in this study. The global efficiency, the clustering coefficient (CC), the characteristic path length (CpL), and "small-world" property were calculated in a wide range of thresholds and averaged within each group, at three different frequency bands (0.01-0.06 Hz, 0.06-0.11 Hz, and 0.11-0.25 Hz). RESULTS At lower-frequency bands (0.01-0.06 Hz, 0.06-0.11 Hz), the global efficiency, the CC and the "small-world" properties of AD patients decreased compared to controls. While at higher-frequency bands (0.11-0.25 Hz), the CpL was much longer, and the "small-world" property was disrupted in AD, particularly at a higher threshold. The topological properties changed with different frequency bands, suggesting the existence of disrupted global and local functional organization associated with AD. CONCLUSIONS This study demonstrates that the topological alterations of large-scale functional brain networks in AD patients are frequency dependent, thus providing fundamental support for optimal frequency selection in future related research.

To overcome the wide range of anatomical variability in clinical cases and the inconsistency of imaging protocols, we introduced the Gross feature recognition of Anatomical Images based on Atlas grid (GAIA), in which the local intensity alteration, caused by pathological (e.g., ischemia) or physiological (development and aging) intensity changes, as well as by atlas–image misregistration, is used to capture the anatomical features of target images. As a proof-of-concept, the GAIA was applied for pattern recognition of the neuroanatomical features of multiple stages of Alzheimer's disease, Huntington's disease, spinocerebellar ataxia type 6, and four subtypes of primary progressive aphasia. For each of these diseases, feature vectors based on a training dataset were applied to a test dataset to evaluate the accuracy of pattern recognition. The feature vectors extracted from the training dataset agreed well with the known pathological hallmarks of the selected neurodegenerative diseases. Overall, discriminant scores of the test images accurately categorized these test images to the correct disease categories. Images without typical disease-related anatomical features were misclassified. The proposed method is a promising method for image feature extraction based on disease-related anatomical features, which should enable users to submit a patient image and search past clinical cases with similar anatomical phenotypes. A novel method to convert anatomical brain MRIs to feature vectors is introduced. Degree of local atlas–image disagreement is used to capture the anatomical features. The method was applied for pattern recognition of various neurodegenerative diseases. The feature vectors agreed well with the known pathological hallmarks of diseases. The method accurately categorized test images to the correct disease categories.

Abstract
Increasing evidence has demonstrated that white matter (WM) disruptions, due to the injury of the axon and myelin, play an important role in the pathogenesis of Alzheimer's disease (AD). Diffusion tensor imaging (DTI) is a sensitive modality to evaluate the WM integrity in both AD patients and animal models. In this study, an advanced DTI modality, employing a 7.0-T magnetic resonance imaging system, was used to analyze WM changes across the whole brain of an amyloid precursor protein/presenilin 1 (APP/PS1) mouse model. A voxel-based analysis was used to compare the quantitative DTI parameters automatically in both APP/PS1 mice (n = 9) and wild-type (WT) controls (n = 9). After DTI examination, the ultrastructure analysis was compared with DTI findings. Compared with WT controls, gray matter (GM) areas in APP/PS1 mice such as the cingulate cortex and the striatum showed significant fractional anisotropy (FA) and axial diffusivity (DA) increase, while the thalamus only showed a significant FA increase (p < 0.01). Similarly, a significant mean diffusivity, DA, and radial diffusivity increase was observed in the bilateral neocortex (p < 0.01). The left hippocampus only showed significant FA increase in APP/PS1 mice (p < 0.01). The changes in WM regions were detected in the forceps minor of the corpus callosum, the anterior part of the anterior commissure, and the internal capsule, with a significant FA or DA increase (p < 0.01). Abnormalities derived from diffusion measurements were in-line with the ultrastructure findings, including extensive pathological damage of the neurons, neutrophils, and vessels. In conclusion, voxel-based diffusion tensor imaging can detect diffusion alterations not only in GM but also in WM areas in AD models, reflecting the extensive pathological changes of AD.

Abstract
β-amyloid (Aβ) aggregates are known to induce neuronal and synaptic dysfunction, and thus are involved in learning and memory deficits in Alzheimer's disease (AD), making Aβ deposits a potential target for prevention or treatment. Microglia, especially bone marrow-derived microglia (BMDM), has been recently thought to play important roles in internalizing and phagocytozing Aβ. BMDM originate in the bone marrow, migrate into the blood as hematopoietic progenitor cells (HPCs) and enter the brain in a chemokine-dependent manner. An effective chemoattractant for HPCs is stromal cell-derived factor 1 (SDF-1), which is also involved in regulating HPCs differentiation. Therefore, we hypothesize that SDF-1 might have influence on the migration of BMDM from peripheral cycle to brain. To explore whether treatment with SDF-1α can decrease Aβ burden, APP/PS1 double transgenic mice were given intracerebroventricular injection of SDF-1α weekly from the age of 28 to 32 weeks (4 weeks of injections) or from 28 to 36 weeks (8 weeks of injections). The results of our study showed that SDF-1α treatment decreased the area and the number of Aβ deposits, increased the level of Iba-1, a marker of microglia, and increased the number of plaque associated microglia in the parenchyma of APP/PS1 transgenic mice. These results suggest that SDF-1 could provide a novel and promising target for the purpose of lowering Aβ pathology in AD.

Abstract
Reactive astrogliosis is one of the key components of the cellular response to CNS injury and is considered a major impediment to axonal regeneration. Our previous study demonstrated that cell cycle inhibition treatment can reduce astrocyte activation and proliferation in vivo. In this study, we examined whether reactive astrogliosis can be suppressed by X-irradiation in vitro by modulating cell cycle progression. X-irradiation with low dose (4 Gy) suppressed astrocyte proliferation as demonstrated by immunofluorescence staining with BrdU and Ki67 in monolayer astrocyte cultures and those in scratch-wound model. The proportions of BrdU (+) and Ki67 (+) cells at 12, 24, and 48 h after 4 Gy irradiation were significantly lower than those in control group. FACS analysis of monolayer astrocyte cultures showed that X-irradiation decreased the proportion of astrocytes in S phase at 12 and 24h after irradiation with a dose-dependent manner. Furthermore, after X-irradiation, higher levels of p53 were observed by western blot as compared to control astrocyte cultures. Taken together, these data support that X-irradiation can decrease astrogliosis via arresting the cell cycle progression, which might constitute an effective therapeutic intervention in diseases characterized by excessive proliferation of glial cells.

Abstract
The present study evaluated autophagy activation in astrocytes and its contribution to astrocyte injury induced by cerebral ischemia and hypoxia. Focal cerebral ischemia was induced by permanent middle cerebral artery occlusion (pMCAO) in rats. In vitro hypoxia in cultured primary astrocytes was induced by the oxygen-glucose deprivation (OGD). Alterations of astrocytes were evaluated with astroglia markers glial fibrillary acidic protein (GFAP). The formation of autophagosomes in astrocytes was examined with transmission electron microscopy (TEM). The expression of autophagy-related proteins were examined with immunoblotting. The role of autophagy in OGD or focal cerebral ischemia-induced death of astrocytes was assessed by pharmacological inhibition of autophagy with 3-methyladenine (3-MA) or bafilomycin A(1) (Baf). The results showed that GFAP staining was reduced in the infarct brain areas 3-12 h following pMCAO. Cerebral ischemia or OGD induced activation of autophagy in astrocytes as evidenced by the increased formation of autophagosomes and autolysosomes and monodansylcadaverine (MDC)-labeled vesicles; the increased production of microtubule-associated protein 1 light chain 3 (LC3-II ); the upregulation of Beclin 1, lysosome-associated membrane protein 2 (LAMP2) and lysosomal cathepsin B expression; and the decreased levels of cytoprotective Bcl-2 protein in primary astrocytes. 3-MA inhibited OGD-induced the increase in LC3-II and the decline in Bcl-2. Furthermore, 3-MA and Baf slightly but significantly attenuated OGD-induced death of astrocytes. 3-MA also significantly increased the number of GFAP-positive cells and the protein levels of GFAP in the ischemic cortex core 12 h following pMCAO. These results suggest that ischemia or hypoxia-induced autophagic/lysosomal pathway activation may at least partly contribute to ischemic injury of astrocytes.

Abstract
BACKGROUND Gallbladder cancer is a common and lethal digestive malignancy which is nonsensitive to routine chemotherapy. Doxorubicin (DOX) is one of the major chemotherapeutic drugs for patients with gallbladder cancer. We tried to evaluate if combined use of somatostatin (SST) and DOX could have synergistic effect in the treatment of gallbladder cancer. METHODS Cells from the human gallbladder cancer cell line GBC-SD were treated with SST. Cell cycle analysis was determined by flow cytometry. Western blot analysis was performed to determine the protein levels of topoisomerase IIalpha (Topo IIalpha) after SST treatment. RT-PCR was utilized to detect SST receptors in GBC-SD cells. Finally, the chemotherapeutic effect of DOX combined with SST treatment on cellular growth was measured by MTT assay. RESULTS SST could induce cell cycle arrest in S phase and upregulate Topo IIalpha expression in GBC-SD cells. GBC-SD cells expressed all 5 subtypes of SST receptors. Finally, combined use of DOX with SST had a synergistic cytotoxic effect on GBC-SD cells. CONCLUSION SST, a naturally occurring, nontoxic compound, may represent a novel adjuvant chemotherapeutic agent for patients with gallbladder cancer.
