Background Along with increasing research on acupuncture for chronic pain, the validity of sham acupuncture (SA) has also been argued. Methods Nine databases were searched for randomized controlled trials (RCTs) from the inception dates of the databases to July 5, 2022. With Markov Chain Monte Carlo methods, a Bayesian multiple-treatment network meta-analysis (NMA) with random-effects model was conducted. Results A total of 62 RCTs with 6,806 patients and four kinds of treatments (real acupuncture [RA], non-acupuncture [NA], penetrative SA [PSA], and non-penetrative SA [NPSA]) were included. The results indicated that both NPSA and PSA were not superior to NA in improving chronic pain (NPSA: mean difference [MD]= –4.77, 95% confidence interval [CI] –11.09 to 1.52; PSA: MD= –4.96, 95% CI –10.38 to 0.48). After NPSA and PSA were combined into the SA group, the weak trend of pain relief from SA was still not statistically significant (MD= –4.91, 95% CI –9.93 to 0.05). NPSA and PSA had similar effects (MD= 0.18, 95% CI –5.45 to 5.81). RA was significantly associated with pain relief, compared with NPSA and PSA (NPSA: MD= –12.03, 95% CI –16.62 to –7.41; PSA: MD= –11.85, 95% CI –15.48 to –8.23). The results were generally consistent regardless of pain phenotype, frequency, duration, acupuncture methods, analgesic intake, or detection bias. Conclusion These results suggested that acupuncture was significantly associated with reduced chronic pain. The two kinds of placebo acupuncture, NPSA and PSA, have similar effects. Both NPSA and PSA, with a weak but not significant effect, are appropriate to be inert placebo controls in RCTs for chronic pain.

Therapeutic irradiation is commonly used to treat brain cancers but can induce cognitive dysfunction, especially in children. The mechanism is unknown but likely involves alterations in dendritic spine number and structure.To explore the impact of radiation exposure on the alteration of dendritic spine morphology in the hippocampus of young brains, 21-day-old Sprague-Dawley rats received cranial irradiation (10 Gy), and changes in spine density and morphology in dentate gyrus (DG) granules and CA1 pyramidal neurons were detected 1 and 3 months later by using Golgi staining. Moreover, we analyzed synapse-associated proteins within dendritic spines after irradiation.Our data showed that cognitive deficits were detected in young rats at both time points postirradiation, accompanied by morphological changes in dendritic spines. Our results revealed significant reductions in spine density in the DG at both 1 month (40.58%) and 3 months (28.92%) postirradiation. However, there was a decrease in spine density only at 1 month (33.29%) postirradiation in the basal dendrites of CA1 neurons and no significant changes in the apical dendrites of CA1 neurons at either time point. Notably, among our findings were the significant dynamic changes in spine morphology that persisted 3 months following cranial irradiation. Meanwhile, we found that depletion of the synapse-associated proteins PSD95 and Drebrin coincided with alterations in dendritic spines.These data suggest that the decreased levels of PSD95 and Drebrin after ionizing radiation may cause changes in synaptic plasticity by affecting the morphological structure of dendritic spines, blocking the functional connectivity pathways of the brain and leading to cognitive impairment. Although the mechanism involved is unclear, understanding how ionizing radiation affects young brain hippocampal tissue may be useful to gain new mechanistic insights into radiation-induced cognitive dysfunction.

Despite significant advances in targeted and immune therapy for non-small cell lung cancer (NSCLC), effective therapies for wild-type epidermal growth factor receptor/anaplastic lymphoma kinase ( EGFR/ALKWT) with low expression of programmed death ligand-1 (PD-L1) NSCLC remain elusive. Numerous studies have shown that ferroptosis plays an essential role in antitumor activity. To identify the molecular regulation patterns associated with ferroptosis, 351 EGFR/ALKWT NSCLC samples with low-level PD-L1 were extracted from The Cancer Genome Atlas (TCGA) and clustered using the k-means clustering technique. The two clusters associated with ferroptosis showed significantly different prognoses. In total, 169 differential expression genes (DEGs) were identified. Cluster differential analysis revealed that Cluster 1 had a significantly poorer overall survival (OS) and was associated with more negative immune regulation. In addition, TCGA samples were randomly assigned in a 7:3 ratio to a training group or testing group. A signature of eight genes associated with ferroptosis was established in the training cohort using DEGs and validated in the test cohort and three independent cohorts (GSE72049, GSE41271, and GSE50081). The 5-year area under the curve (AUC) was 0.713, which was significantly higher than that of other predictors, including TNM stage and age. Furthermore, the risk score was associated with immune function, immune infiltration, and immunotherapy response, with high-risk patients having a worse prognosis, an immune-suppressing phenotype, and a poor response to immune checkpoint inhibitors. This study aims to contribute to our understanding of the biological role of ferroptosis in EGFR/ALKWT NSCLC with low-level PD-L1, laying the groundwork for the development of novel therapeutic strategies.

This study aimed to assess the clinical characteristics affecting outcomes after immune checkpoint inhibitors (ICI) therapies in non-small cell lung cancer (NSCLC) patients, and the underlying mechanism in tumor immune micro-environment (TIME).A total of 144 patients treated with ICI-based strategies were retrospectively analyzed. Expression of 10 immune antibodies in tumor tissues from other 60 untreated NSCLC patients were sequentially tested using multiplexed immunofluorescence (mIF) staining method. Correlation of clinical characteristics with ICI treatment outcomes and TIME characteristics were analyzed.Multivariate logistic and cox regression indicated that BoM negatively affected disease control rate (OR = 0.32, 95%CI: 0.13-0.82, P = 0.018), progression free survival (HR = 3.44, 95% CI:1.97-6.00, P 0.001) and overall survival (HR = 3.24, 95% CI:1.62-6.50, P = 0.001), irrespective of programmed death-ligand 1 (PD-L1) expression. BoM patients were with significantly lower PD-L1, and this heterogeneity of TIME was then confirmed in the mIF staining, where 36 (61.0%) patients were clustered into immune-subtype A, with low expression of all the detected immune markers, similar to "cold" tumors, and 23 (39.0%) in cluster B with likely "hot" tumors. More patients in immune-subtype A were non-smokers (63.9% vs. 39.1% P = 0.063), with BoM (66.7% vs. 21.7%, P = 0.001), in stage IV(88.9% vs. 65.2%, P = 0.045), and with adenocarcinoma (91.7% vs. 69.6%, P = 0.037). Multivariate logistic regression indicated that BoM was independently associated with the "cold" immune characteristics (OR = 0.19, 95% CI:0.04-0.84, P = 0.028). Combination therapy with chemotherapy /antiangiogenesis or use of bisphosphonate during ICI treatment significantly improved clinical outcomes in BoM patients.BoM displays adverse impact on clinical outcomes after ICI treatments in NSCLC patients. The "cold" characteristics of TIME may be the underlying mechanism for the attenuated efficacy of ICIs in bone metastatic NSCLC patients.

As one of the key technologies for intensive additive repair (i.e., using a type of powder to repair various substrates), the method of accurately predicting the strength of repaired samples based on the chemical composition of filling materials and base materials needs to be explored urgently. An intensive additive repair experiment based on the laser coaxial powder feeding cladding technology was carried out using an independently designed intensive high-strength martensitic stainless steel (IHMSS) powder and eight types of substrates. A new approach was presented: the distance between the composition points of the IHMSS powder and the substrate to be repaired, as shown in Schaeffler's diagram (D), and their orientation relationship (θ) can provide a basis for describing the bonding strength of the repaired interface between the aforementioned materials. With the increase in D and θ, the ratios of tensile strength and elongation of additive repair parts to those of base materials decreased. When θ was below 1.12, the tensile strength of repaired interface in the normal direction was more than 83% that of the substrate to be repaired. Incomplete fusion and cracks were found on the cross section of the additive parts when θ exceeded 1.12. When D exceeded 13%, a high microhardness phase was formed near the interface. Further analysis results show that, with the increase in D and θ, the gradients of microstructure, composition, and microhardness at the repaired interface will be increased.

The goal of this study was to identify genes that were differentially methylated and differentially expressed and their related signaling pathways in ovarian endometriosis tissue. First, the DNA methylation and gene expression profiles in the endometrial tissue of patients with ovarian endometriosis were studied using Illumina 450K methylation microarray analysis and the GSE141549 gene expression dataset. Second, differentially methylated and differentially expressed genes, herein referred to as differentially methylated/expressed genes, were identified and protein-protein interaction networks and functional analysis of these genes were determined. Third, qPCR and immunohistochemistry of patient samples was used to confirm the differential expression of a subset of differentially methylated/expressed genes. Finally, the GSE7305 dataset was used confirm the expression profile of differentially methylated/expressed genes and to determine the potential usefulness of these genes for diagnosis of endometriosis. A total of 37 hypermethylated low-expression genes and 66 hypomethylated high-expression genes were identified in ovarian endometriosis patients. Protein-protein interaction and functional analysis highlighted 8 hypermethylated low-expression genes (KRT19, KRT8, ESR1, PRL, SFN, IL20RA, IL2RB, and PAX8) and 4 hypomethylated high-expression genes (CYP11A1, NR5A1, ME1, and GSTM1). Significantly, both of these gene sets had a diagnostic value for patients with ovarian endometriosis. Signaling pathways that were identified included JAK-STAT (involving IL20RA and IL2RB), prolactin (involving PRL and ESR1), Staphylococcus aureus infection (involving KRT19), viral protein interaction with cytokine and cytokine receptor (involving IL20RA and IL2RB), cytokine-cytokine receptor interaction (involving IL20RA and IL2RB), and drug metabolism-cytochrome P450 (involving GSTM1). The differentially methylated/expressed genes and enriched signaling pathways identified in this study are likely to be associated with the process of ovarian endometriosis.

- Abstract
This paper studies a wireless power communication network(WPCN) based on orthogonal frequency division multiplexing (OFDM) with time reversal(TR). In this paper, the " Harvest Then Transmit " protocol is adopted, and the transmission time block is divided into three stages, the first stage is for power transmission, the second stage is for TR detection, and the third stage is for information transmission. The energy limited access point (AP) and the terminal node obtain energy from the radiofrequency signal sent by the power beacon (PB) to assist the terminal data transmission. The energy limited AP and the terminal node obtain energy from the radio frequency signal sent by the PB to assist the terminal data transmission. In the TR phase and the wireless information transmission (WIT) phase, the terminal transmits the TR detection signal to the AP using the collected energy, and the AP uses the collected energy to transmit independent signals to a plurality of terminals through OFDM. In order to maximize the sum rate of WPCN, the energy collection time and AP power allocation are jointly optimized. Under the energy causal constraint, the subcarrier allocation, power allocation and time allocation of the whole process are studied, and because of the binary variables involved in the subcarrier allocation, the problem belongs to the mixed integer non-convex programming problem. the problem is transformed into a quasiconvex problem, and then binary search is used to obtain the optimal solution. The simulation results verify the effectiveness of this scheme. The results show that the proposed scheme significantly improves the sum rate of the terminal compared to the reference scheme.

- Abstract
Epidemiologic studies have explored the association between a single cardiovascular risk factor (CVRF) and resting heart rate (RHR), but the research on the relation of multiple risk factors with RHR remains scarce. This study aimed to explore the associations between CVRFs clustering and the risk of elevated RHR.In this cross-sectional study, adults aged 35-75 years from 31 provinces were recruited by the China PEACE Million Persons Projects from September 2015 to August 2020. We focused on seven risk factors: hypertension, diabetes mellitus, dyslipidemia, obesity, smoking, alcohol use, and low physical activity. Multivariate logistic regression was used to calculate odds ratios (OR) for elevated RHR (80 beats/min).Among 1,045,405 participants, the mean age was 55.67 ± 9.86 years, and 60.4% of participants were women. The OR (95% CI) for elevated RHR for the groups with 1, 2, 3, 4 and ≥ 5 risk factor were 1.11 (1.08-1.13), 1.36 (1.33-1.39), 1.68 (1.64-1.72), 2.01 (1.96-2.07) and 2.58 (2.50-2.67), respectively (There was a significant positive association between the CVRFs clustering number and the risk of elevated RHR, particularly in young males. Compared clusters comprising more behavioral risk factors, clusters comprising more metabolic risk factors were associated with a higher risk of elevated RHR. RHR may serve as an indicator of the cumulative effect of multiple risk factors.

Background: The aim of the study was to investigate the role of the genetic variation of glutathione S-transferase M1 (GSTM1) in the development of ovarian endometriosis and endometriosis-related primary infertility risk. Methods: This case-control study included 564 women with ovarian endometriosis and 576 normal women in the control group in northern China. The polymorphism of GSTM1 was genotyped by polymerase chain reaction (PCR)/ligase detection reaction method. To assess the biological significance of polymorphisms, the level of GSTM1 mRNA expression in patients’ endometrial tissues with different genotypes was detected by quantitative real-time PCR (qRT-PCR). Results: Compared with the positive genotype, the null genotype of GSTM1 was associated with the risk of developing ovarian endometriosis (OR = 1.29, 95% CI = 1.02–1.62). Further analysis showed that patients with a null genotype also had a significantly higher risk of primary infertility than patients with positive genotypes (OR = 1.59, 95% CI = 1.01–2.49). In addition, we found that GSTM1 mRNA expression was present in the endometrial tissue of all patients, but the expression level of patients with a positive genotype was nearly 10 times higher than that of patients with a negative genotype. Conclusion: Our results suggest that the GSTM1 polymorphism is not only related to the genetic susceptibility to ovarian endometriosis but also a potential molecular marker of primary infertility in patients with ovarian endometriosis.

By taking molybdenum (Mo) having favorable metallurgical compatibility with both titanium and iron as the interlayer material, the butt joint of TA1/Q235B layered bimetallic sheet with thickness of 6 mm was prepared by utilizing narrow gap multi-pass laser welding with low heat input. Mo generally can favorably isolate Ti from Fe, meanwhile the transition zone of Mo and steel adjacent to Mo interlayer was softened according to the results of microhardness test. The results of face bending testing showed that the softened zone was beneficial to the mechanical properties of the welded joint, which could restrict the crack propagation along the interface of Mo/steel in fusion zone so that fracture appeared in the BM side. The microstructures of the softened zone exhibited a low dislocation density observed by a transmission electron microscope (TEM), which may be the main reason leading to a low microhardness. In additon, Mo interlayer was confined in a small zone, which only accounted for about 6.5% of the total area of cross section of the fusion zone while a small amount of FeTi and λ brittle intermetallic compounds (IMCs) still appeared around the Mo/steel interface in fusion zone. The tensile strength of the welded joint was 467 MPa, which took up about 93% that of base metal. The results of this paper will help guide endeavours for the fabrication of pipes and containers made of Ti/steel bimetallic sheets.

MBLS10A-200 magnesium-lithium (Mg-Li) alloy is a novel ultralight material, with the density, tensile strength and elongation rate of 1.5 g/cm3, 160 MPa and 60%, respectively. At present, the material is increasingly widely applied in structures with complex shapes of various fields such as aeronautics, astronautics and electronic engineering. At present, the industrial circle has put forward increasingly urgent demand for the welding technique of MBLS10A-200 alloy and the protection technology for corrosion resistance of the welded joints of the alloy. However, related research is rarely reported. Laser welding of MBLS10A-200 Mg-Li alloy with 5 mm in thickness was studied to further obtain the butt joint, with the elongation rate of about 54% and the same strength as base metal (BM). Moreover, the corrosion resistance of laser welded joint was detected by using electrochemistry method. During the experiment, it can be found that the corrosion resistance of metals in the welded seam zone (WSZ) was far higher than that of the BM. The corrosion current density of metals in WSZ was about 10-5 A/cm2, which declined by two orders of magnitude compared with BMs which were about 10-7 A/cm2 and the charge transfer resistance of welded seam zone increased by 4.8 times compared with BMs.

In Part Ⅰ of this series, it can be found that the corrosion resistance of metals in the welded seam zone (WSZ) was far higher than that of the base metal (BM) of MBLS10A-200 Mg-Li alloy. Therefore, the feasibility of improving the corrosion resistance of MBLS10A-200 Mg-Li alloy through laser surface melting (LSM) was further explored. Meanwhile, laser shock peening (LSP) treatment was also used for contrast. The results showed that the surface melted zone with the corrosion resistance through LSM superior to that of metals in WSZ of MBLS10A-200 alloy through laser welding can be prepared by controlling heat input through increasing the scanning speed of laser beam, while LSP has limited impact on the electrochemical corrosion resistance of MBLS10A-200 alloy. The corrosion current density (Jcorr) of the samples subjected LSM declined by two orders of magnitude compared with the base metal (BM) while the charge transfer resistance increased by 17 times compared with BM. An analysis indicated that owing to the fast cooling rate during laser processing, the multi-phase microstructures (i.e. α phase, β phase and Li2MgAl) of BM were transformed into β single-phase microstructure in WSZ and surface melted zone. In this way, not only solid solution strengthening of the metals in WSZ was realized but also the micro-galvanic coupling generated due to the difference of electric potentials of multi-phase microstructures were reduced, thus improving the corrosion resistance of surface melted zone.

Sepsis-induced multiple organ dysfunction and inflammatory response are life-threatening symptoms without effective treatment. Fisetin, a dietary flavonoid extracted from berries and family Fabaceae, has displayed neuroprotective and anti-oxidant activities. In this study we investigated whether fisetin exerted a protective effect against sepsis-induced multiple organ dysfunction in mouse cecum ligation and puncture (CLP) model. The mice were injected with fisetin (10 mg/kg, ip) 0.5 h prior to CLP, and sacrificed 18 h after CLP. We found that fisetin administration significantly alleviated CLP-induced lung, liver and kidney injury, as well as the expression levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α and IL-1β in bronchoalveolar lavage fluid (BALF). In lipopolysaccharide (LPS)-treated mouse bone marrow-derived macrophages (BMDMs), application of fisetin (3–10 μM) dose- dependently inhibited the expression levels of IL-6, TNF-α, IL-1β, and inducible nitric oxide synthase (iNOS). Furthermore, fisetin dose-dependently inhibited the phosphorylation of p38 MAPK, MK2, and transforming growth factor-β-activated kinase (TAK) 1 via attenuating the interaction between TAK1 and TAK-binding proteins (TAB) 1. These results demonstrate that fisetin is a promising agent for protecting against sepsis-induced inflammatory response and organ injury via inhibiting macrophage activation.

Gastrointestinal cancers (GICs) occupy more than 30% of the cancer-related incidence and mortality around the world. Despite advances in the treatment strategies, the long-term overall survival has not been improved for patients with GICs. Recently, the novel patient-derived organoid (PDO) culture technology has become a powerful tool for GICs in a manner that recapitulates the morphology, pathology, genetic, phenotypic, and behavior traits of the original tumors. Excitingly, a number of evidences suggest that the versatile technology has great potential for personalized treatment, suppling the clinical application of molecularly guided personalized treatment. In the paper, we summarize the literature on the topics of establishing organoid biobanks of PDOs, and their application in the personalized treatment allowing for radiotherapy, chemotherapy, targeted therapy, and immunotherapy selection for GICs. Despite the limitations of current organoid models, high-throughput drug screening of GIC PDO combined with next-generation sequencing technology represents a novel and pivotal preclinical model for precision medicine of tumors and has a great value in promoting the transformation from basic cancer research to clinical application.

- Abstract
Along with increasing research on acupuncture for chronic pain, the validity of sham acupuncture (SA) has also been argued.Nine databases were searched for randomized controlled trials (RCTs) from the inception date to July 5, 2022. Using Markov Chain Monte Carlo methods, a Bayesian multiple treatment network meta-analysis (NMA) with random-effects model was conducted.A total of 62 RCTs with 6806 patients and four kinds of treatments (real acupuncture (RA), non-acupuncture (NA), penetrative SA (PSA) and non-penetrative SA (NPSA)) were included. The results indicated that both NPSA and PSA were not superior to NA in improving chronic pain (NPSA: MD -4.77 [95% CI, -11.09 to 1.52]; PSA: MD, -4.96 [95% CI, -10.38 to 0.48]). After combining NPSA and PSA into the SA group, the weak trend of pain relief from SA was still not statistically significant (MD, -4.91 [95% CI, -9.93 to 0.05]). NPSA and PSA had similar effects (MD, 0.18 [95% CI, -5.45 to 5.81]). RA was significantly associated with pain relief, compared with NPSA and PSA (NPSA: MD, -12.03 [95% CI, -16.62 to -7.41]; PSA: MD, -11.85 [95% CI, -15.48 to -8.23]). The results were generally consistent regardless of pain phenotype, frequency, duration, acupuncture methods, analgesic intake, or detection bias.These results suggested that acupuncture was significantly associated with reduced chronic pain. The two kinds of placebo acupuncture, NPSA and PSA, have similar effects. Both NPSA and PSA, with a weak but not significant effect, are appropriate to be inert placebo controls in RCTs for chronic pain.

Background Whereas there are many pharmacological interventions prescribed for patients with advanced anaplastic lymphoma kinase (ALK)- rearranged non-small cell lung cancer (NSCLC), comparative data between novel generation ALK-tyrosine kinase inhibitors (TKIs) remain scant. Here, we indirectly compared the efficacy and safety of first-line systemic therapeutic options used for the treatment of ALK-rearranged NSCLC. Methods We included all phase 2 and 3 randomised controlled trials (RCTs) comparing any two or three treatment options. Eligible studies reported at least one of the following outcomes: progression free survival (PFS), overall survival (OS), objective response rate (ORR), or adverse events of grade 3 or higher (Grade ≥ 3 AEs). Subgroup analysis was conducted according to central nervous system (CNS) metastases. Results A total of 9 RCTs consisting of 2484 patients with 8 treatment options were included in the systematic review. Our analysis showed that alectinib (300 mg and 600 mg), brigatinib, lorlatinib and ensartinib yielded the most favorable PFS. Whereas there was no significant OS or ORR difference among the ALK-TKIs. According to Bayesian ranking profiles, lorlatinib, alectinib 600 mg and alectinib 300 mg had the best PFS (63.7%), OS (35.9%) and ORR (37%), respectively. On the other hand, ceritinib showed the highest rate of severe adverse events (60%). Conclusion Our analysis indicated that alectinib and lorlatinib might be associated with the best therapeutic efficacy in first-line treatment for major population of advanced NSCLC patients with ALK-rearrangement. However, since there is little comparative evidence on the treatment options, there is need for relative trials to fully determine the best treatment options as well as the rapidly evolving treatment landscape.

Farnesoid X receptor (FXR) has been identified as an inhibitor of platelet function and an inducer of fibrinogen protein complex. However, the regulatory mechanism of FXR in hemostatic system remains incompletely understood. In this study, we aimed to investigate the functions of FXR in regulating antithrombin III (AT III). C57BL/6 mice and FXR knockout (FXR KO) mice were treated with or without GW4064 (30 mg/kg per day). FXR activation significantly prolonged prothrombin time (PT) and activated partial thromboplastin time (APTT), lowered activity of activated factor X (FXa) and concentrations of thrombin-antithrombin complex (TAT) and activated factor II (FIIa), and increased level of AT III, whereas all of these effects were markedly reversed in FXR KO mice. In vivo, hepatic AT III mRNA and protein expression levels were up-regulated in wild-type mice after FXR activation, but down-regulated in FXR KO mice. In vitro study showed that FXR activation induced, while FXR knockdown inhibited, AT III expression in mouse primary hepatocytes. The luciferase assay and ChIP assay revealed that FXR can bind to the promoter region of AT III gene where FXR activation increased AT III transcription. These results suggest FXR activation inhibits coagulation process via inducing hepatic AT III expression in mice. The present study reveals a new role of FXR in hemostatic homeostasis and indicates that FXR might act as a potential therapeutic target for diseases related to hypercoagulation.

To explore the relationship between effect of induction chemotherapy and prognosis in acute myeloid leukemia (AML) patients.The clinical data of 146 adult AML patients treated in Affiliated Hospital of Chifeng University from March 2015 to March 2018 were enrolled and retrospectively analyzed. Day 14 bone marrow biopsy (D14BM) cellularity and blast proportion, daily peripheral blood blast (PBB) clearance rate, time to PBB clearance and etc. were primarily observed after induction chemotherapy. All the patients were divided into Non-relapse survival group, Relapse survival group, Non-relapse death group and Relapse death group according to survival and recurrence situation during 2-year follow-up. The survival of the patients was analyzed by Kaplan-Meier. Univariate analysis of prognostic factors were performed by ordinal Logistic regression, and ROC curve was used to assess the prediction efficiency of those factors for the 2-year overall survival (OS) and relapse of the patients.A total of 138 patients were included since 8 cases failed to be assessed clinically. Their 2-year OS rate was 65.94%. Age of the patients in Non-relapse survival group was lower than that in Relapse death group. The D14BM cellularities in Non-relapse survival group and Relapse survival group were lower than those in Relapse death group (P0.05). Daily PBB clearance rates in Non-relapse survival group and Relapse survival group were higher than those in Non-relapse death group and Relapse death group (P0.05). There was a statistical difference among the four groups in the number of cycles of induction chemotherapy (P0.05). The survival rate within 2 years in the patients with D14BM cellularity≤10% was higher than that in patients with cellularity10%, while it was higher in patients with daily PBB clearance rate20% than those with clearance rate≤20% (P0.05). Age (HR=1.102, P=0.000), D14BM cellularity (HR=1.252, P=0.000) and the cycles of induction chemotherapy≥3 (HR=1.703, P=0.000) were the risk factors affecting the prognosis of AML patients, while daily PBB clearance rate was a protective factor (HR=0.799, P=0.000). The AUC of age, daily PBB clearance rate and D14BM cellularity in predicting 2-year OS of AML patients was 0.738, 0.817 and 0.807, respectively, whereas in predicting relapse within 2 years it was 0.691, 0.647 and 0.711, respectively. There was no statistical difference among the three factors in the sensitivity of 2-year OS (68.11%, 85.12%, 74.49%) and 2-year relapse (50.00%, 64.13%, 61.60%) (P0.05).Bone marrow biopsy results and PBB clearance rate are related to prognosis in AML patients, which can offer certain predictive value in assessing 2-year OS of patients.AML患者诱导化疗疗效与预后关系分析.探讨急性髓系白血病(AML)患者诱导化疗的治疗效果与预后的关系。.收集并回顾性分析2015年3月至2018年3月本院收治的146例AML成年患者的临床资料,主要观察指标为诱导治疗d 14骨髓(D14BM)增生程度及原始细胞的比例,外周血白血病细胞(PBB)清除时间及日减少率等。根据随访2年患者的存活和复发情况分为无复发存活组、复发存活组、无复发死亡组、复发死亡组。采用Kaplan-Meier法行生存分析,有序Logistic回归分析对预后相关因素行单因素分析,绘制ROC曲线并评估上述指标对患者2年总生存期(OS)和复发的预测效能。.共纳入138例患者,2年OS率65.94%;无复发存活组年龄低于复发死亡组,无复发存活组和复发存活组D14BM增生度低于复发死亡组(均P0.05);无复发存活组和复发存活组PBB日减少率均高于无复发死亡组和复发死亡组(均P0.05);4组化疗次数比较差异有统计学意义(P0.05);D14BM增生≤10%的患者2年内存活率高于增生10%的患者,PBB日减少率20%的患者存活率高于≤20%者(均P0.05);年龄(HR=1.102,P=0.000)、D14BM增生度(HR= 1.252,P=0.000)、化疗次数≥3次(HR=1.703,P=0.000)为影响AML患者预后的危险因素,而PBB日减少率(HR= 0.799,P=0.000)为保护因素;年龄、PBB日减少率、D14BM增生度预测患者2年OS的AUC分别为0.738、0.817、 0.807,预测患者2年内复发的AUC分别为0.691、0.647、0.711,三者预测患者2年OS(68.11%、85.12%、74.49%)和2年内复发(50.00%、64.13%、61.60%)的敏感性均无明显差异(P0.05)。.骨髓活检结果、PBB清除率与AML患者预后相关,可为患者2年OS提供一定预测价值。.

- Abstract
Background: Computerized clinical decision support systems (CDSS) are low-cost, scalable tools with the potential to improve guideline-based antihypertensive treatment in primary care, but their effectiveness needs testing in pragmatic trials. Methods: The Learning Implementation of Guideline-based decision support system for Hypertension Treatment (LIGHT) trial is a pragmatic, four-stage, cluster-randomized trial conducted in 94 primary care practices in China. For each city-based stage, practices are randomly assigned to either implementation of the CDSS for hypertension management (which guides physicians treatment recommendations based on measured blood pressure and patient characteristics), or usual care. Patients are enrolled during the first 3 months after site randomization and followed for 9 months. The primary outcome is the proportion of hypertension management visits at which guideline-based treatment is provided. In a separate sub-study conducted within the CDSS, with the patient as the unit of randomization, the LIGHT-ACD trial, patients are randomized to receive different initial mono- or dual- antihypertensive therapy. The primary outcome of the LIGHT-ACD trial is the change in blood pressure from the first visit after site randomization to 9 months.Discussion: The LIGHT trial will provide evidence on the effectiveness of a CDSS for improving guideline adherence for hypertension management in primary care in China. The sub-study, LIGHT-ACD trial, will provide data on the effect of different initial antihypertensive regimens for blood pressure management in this setting.Trial registration: ClinicalTrials.gov, identifier: LIGHT (NCT03636334) and LIGHT-ACD (NCT03587103). Registered on 3 July 2018.

Owing to the high morbidity and mortality, novel biomarkers in the occurrence and development of colorectal cancer (CRC) are needed nowadays. In this study, the CRC-related datasets were downloaded from the Gene Expression Omnibus (GEO) database and The Cancer Genome Atlas (TCGA) database. After screening the differentially expressed genes (DEGs) in R software, a total of 238 upregulated and 199 downregulated DEGs were revealed simultaneously. Then the Kaplan-Meier survival analysis and Cox regression analysis were used to reveal the prognostic function of these DEGs. Neurexophilin and PC-esterase domain family member 4 (NXPE4) and prostate androgen-regulated mucin-like protein 1 (PARM1) were two outstanding independent overall survival (OS) and relapse-free survival (RFS) prognostic genes of CRC in TCGA database. We next verified the expression of NXPE4 and PARM1 messenger RNA (mRNA) levels were significantly lower in CRC tumor tissue than in the adjacent noncancerous tissue in our clinical samples, and NXPE4 mRNA expression level was related to the tumor location and tumor size, while PARM1 was related to tumor location, lymph nodes metastasis, and tumor size. This study demonstrated that NXPE4 and PARM1 might be two potential novel prognostic biomarkers for CRC.

Objective High-grade serous ovarian cancer (HGSOC) is a deadly malignancy. Homeobox protein A9 ( HOXA9) is linked with serous papillary histotype differentiation, and inappropriate HOXA9 expression is a step in ovarian cancer that induces aberrant differentiation. This study aimed to reveal the significance of HOXA9 in HGSOC. Methods HOXA9 mRNA and protein expression were examined by quantitative PCR and immunohistochemistry, respectively. The chi-square test was used to evaluate associations between HOXA9 expression and clinical characteristics. The prognostic value of HOXA9 was calculated by the Kaplan–Meier method. The Kaplan–Meier Plotter database was used to assess the prognostic value of HOXA9. Results The mRNA and protein expression of HOXA9 were significantly upregulated in chemotherapy-resistant HGSOC compared with chemotherapy-sensitive HGSOC. The chi-square test showed that high HOXA9 expression was significantly related with grade, clinical stage, and residual disease. High HOXA9 expression was significantly associated with poor prognosis. The Kaplan–Meier Plotter database further confirmed these results. Cox hazard regression showed that high HOXA9 expression was an independent prognostic factor for survival in HGSOC patients. Conclusion This study showed that HOXA9 expression was associated with chemotherapy resistance and poor outcomes in HGSOC patients. High HOXA9 expression might be a prognostic indicator for HGSOC.

Context Patients with gastric cancer experience health-related quality of life (HRQOL) decline during adjuvant chemotherapy following gastrectomy. Objectives This pilot study aimed to evaluate the preliminary effect and feasibility of electro-acupuncture (EA) for HRQOL and symptom burden in these patients. Methods In this open-label, multicenter, parallel controlled trial, gastric cancer patients who planned to receive adjuvant chemotherapy were randomly assigned to receive high-dose EA (seven times each chemotherapy cycle for three cycles), low-dose EA (three times each chemotherapy cycle), or usual care only. The acupoints prescription consisted of bilateral ST36, PC6, SP4, and DU20, EX-HN3, and selected Back-shu points. Patients completed the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga) weekly, and the Edmonton Symptom Assessment System (ESAS). The primary outcome was the difference among the groups on the gastric cancer subscale (GaCS) of the FACT-Ga. Results Of the 66 randomized patients, 58 were analyzed according to intention-to-treat principle, and 45 were in the per-protocol set (PPS). The average scores in PPS of GaCS were 52.12±9.71, 51.85±12.36, and 45.37±8.61 in high-dose EA, low-dose EA, and control groups, respectively. EA was significantly associated with improved average GaCS scores when compared with control group (51.98±10.91 vs. 45.37±8.61, P = 0.039). EA treatment also produced ESAS relief at the end of intervention (14.36 ± 12.28 vs. 23.91 ± 15.52, P = 0.027). Participants in EA groups had fewer grade ≥3 leukopenia (0% vs. 15.79%, P = 0.031) and neutropenia (2.56% vs. 26.31%, P = 0.012). Conclusion EA showed promising effects in improving HRQOL, controlling symptom burden, and reducing toxicity during adjuvant chemotherapy in gastric cancer patients. Future adequately powered trials are feasible and needed to confirm the specific effect of EA.

General Physics and Astronomy - Abstract
An n-GaO x thin film is deposited on a single-crystal boron-doped diamond by RF magnetron sputtering to form the pn heterojunction. The n-GaO x thin film presents a small surface roughness and a large optical band gap of 4.85 eV. In addition, the band alignment is measured using x-ray photoelectron spectroscopy to evaluate the heterojunction properties. The GaO x /diamond heterojunction shows a type-II staggered band configuration, where the valence and conduction band offsets are 1.28 eV and 1.93 eV, respectively. These results confirm the feasibility of the use of n-GaO x as a termination structure for diamond power devices.

More than 20 types of ALK fusion variant subtypes have been identified, including different fusion partner genes or EML4-ALK fusions with different breakpoints. However, different ALK fusions show different sensitivities to ALK-tyrosine kinase inhibitors (ALK-TKIs) and the emergence of rare fusions brings great challenges to the target therapy in clinic. We report a rare EML4-ALK (E6;A18) fusion in a patient with lung adenocarcinoma that responded well to alectinib. This is the second case of this rare variant reported but the first report of response to an ALK-TKI. This evidence is the first to show that alectinib may be effective for this rare fusion type of non–small cell lung cancer, and these findings have important implications for drug selection in patients with this subtype. Further studies are needed to understand the function of this variant.

Aberrant DNA methylation is considered to play a critical role in the chemoresistance of epithelial ovarian cancer (EOC). In this study, we explored the relationship between hypermethylation of the Mahogunin Ring Finger 1 (MGRN1) gene promoter and primary chemoresistance and clinical outcomes in high-grade serous ovarian cancer (HGSOC) patients. The MALDI-TOF mass spectrometry assays revealed a strong association between hypermethylation of the MGRN1 upstream region and platinum resistance in HGSOC patients. Spearman’s correlation analysis revealed a significantly negative connection between the methylation level of MGRN1 and its expression in HGSOC. In vitro analysis demonstrated that knockdown of MGRN1 reduced the sensitivity of cells to cisplatin and that expression of EGR1 was significantly decreased in SKOV3 cells with low levels of MGRN1 expression. Similarly, EGR1 mRNA expression was lower in platinum-resistant HGSOC patients and was positively correlated with MGRN1 mRNA expression. Kaplan-Meier analyses showed that high methylation of the MGRN1 promoter region and low expression of MGRN1 were associated with worse survival of HGSOC patients. In multivariable models, low MGRN1 expression was an independent factor predicting poor outcome. Furthermore, low expression of EGR1 was also been confirmed to be significantly related to the poor prognosis of HGSOC patients by Kaplan-Meier. The hypermethylation of the MGRN1 promoter region and low expression of MGRN1 were associated with platinum resistance and poor outcomes in HGSOC patients, probably by altering EGR1 expression.

Background To facilitate biomedical studies of disease mechanisms, a high-quality interactome that connects functionally related genes is needed to help investigators formulate pathway hypotheses and to interpret the biological logic of a phenotype at the biological process level. Results Interactions in the updated version of the human interactome resource (HIR V2) were inferred from 36 mathematical characterizations of 6 types of data that suggest functional associations between genes. This update of the HIR consists of 88,069 pairs of genes representing functional associations that are of strengths similar to those between well-studied protein interactions. Among these functional interactions, 57.04% may represent protein interactions, which are expected to cover 32.48% of the true human protein interactome. The gene set linkage analysis (GSLA) tool is developed based on the high-quality HIR V2 to identify the potential functional impacts of observed transcriptomic changes, helping to elucidate their biological significance and complementing the currently widely used enrichment-based gene set interpretation tools. Conclusions We present the HIR V2, a high-quality functional interactome of human genes, along with the gene set linkage analysis (GSLA) webtool, which utilizes the HIR V2 to interpret the biological significance of transcriptionally changed genes. A case study shows that the annotations reported by the HIR V2/GSLA system are more comprehensive and concise compared to those obtained by widely used gene set annotation tools such as PANTHER and DAVID. The HIR V2 and GSLA are available at http://human.biomedtzc.cn .

The efficient and rational development of tight gas reservoirs, most of which are deposit of multiple layers, is becoming a new global focus. The major tight gas reservoirs in China have multiple production layers. Gas wells are completed with multiple fracture treatments, and are commingled production. It is very difficult to effectively evaluate the single-layer production contribution and the use of each layer’s reserves. This paper presents an approach to solve the problem, which is basically based on the application of Pearson correlation analysis, catastrophe theory, and linear interpolation to calculate the single-layer production allocation rates. The method can quickly evaluate the stratified production of a large number of gas wells at different times through a computer program. The error of method validation, comparing the method prediction value with the production test data, is less than 10%. In field application, after the gas flows the discharge boundary, the production of the main layer will decrease due to the decrease in gas production of the multi-layer gas well, and other non-main layers may rise or have little change. In another case, the non-main layer can produce more natural gas for the gas well increases production. The method will also provide guidance for optimizing the perforation section of a gas well. Additionally, based on the production of a single gas well, the cumulative gas production of each layer can be calculated to evaluate the dynamic reserves of each layer and analyze the reserves utilization of each single layer. This work will finally provide guidance for gas well encryption to improve the multi-layer tight gas reservoir recovery.

Shenmu Gas Field is a multilayer tight sandstone gas reservoir with low vertical well production. The task of gas field productivity construction is heavy. It is an effective way to increase the production of a single well by excavating local superior areas and implementing horizontal well development. Therefore, it is necessary to evaluate the adaptability and establish the reservoir limits of horizontal well in Shenmu Gas Field. Systematically study the superposition mode and development scale of reservoir sand bodies, and use the reserve concentration to divide the multi-layer gas reservoirs into three types, and they are single-layer, double-layer and multi-layer, respectively. The numerical simulation method is used to compare the development effects of horizontal wells and vertical wells, to determine the reserves concentration limits and reserves physical property limits of horizontal well development. The selection criteria for geological targets suitable for horizontal well is established. The research shows that ① A large-scale composite effective reservoir is formed in the local area of the Taiyuan Formation and Shan2 Formation in Shenmu Gas Field, with a length of 1600–3200 m and a width of 800–2000 m, and it has the geological conditions for horizontal well development; ② the reserve concentration in the main development zone of the horizontal well should be over 75%, and it should have a continuous effective thickness of 5.0 m, The permeability ratio between the primary and the secondary layer should be between 0.8 and 3.9; ③ the Shenmu Gas Field is generally not suitable for large-scale horizontal well overall development, but is suitable for centralized development in local single-layer advantageous areas. The research result can provide technical support for the horizontal wells of similar gas reservoirs at home and abroad, and are of great significance for the efficient development of gas fields.

To analyze vascular damage-related risk factors for ED in patients with type 2 diabetes mellitus (DM) and develop a nomogram for the prediction of the factors.A total of 181 patients with type 2 DM were included for sexual function assessment, and the clinical data on vascular damage were retrieved from the patients system. After preprocessing, the data were described by the number and percentage of different types of cases and subjected to statistical analysis with the R software. The Lasso regression model was used to optimize feature selection. On the premise of the sample size required for logistic regression analysis according to the number of events per variable, multivariable logistic regression analysis was performed on the selected variables and a nomogram was developed for diabetes-induced erectile dysfunction (DIED). Then, the performance of the nomogram was evaluated with respect to its calibration, discrimination and clinical utility using Harrell's concordance index (C-index), the calibration plot and decision curve analysis, as well as bootstrapping for internal validation.ED was diagnosed in 90 (49.7%) of the 181 patients. The risk factors subjected to logistic regression analysis included the duration of DM (OR = 4.440, 95% CI: 1.594-13.105; OR = 7.667, 95% CI: 1.444-48.733), status of carotid intima-media thickness (c-IMT) (OR = 3.767, 95% CI: 1.194-12.691), diabetic retinopathy (DR) (OR = 5.382, 95% CI: 1.373-28.301), diabetic kidney disease (DKD) (OR = 4.959, 95% CI: 1.156-27.728), low-density lipoprotein cholesterol (LDL-C) (OR = 8.210, 95% CI: 2.027-43.507), red blood cell distribution width (RDW) (OR = 2.418, 95% CI: 1.021-5.826), and plasma fibrinogen (Fbg) (OR = 4.649, 95% CI: 2.001-11.339). The C-index of the DIED model was 0.911 (95% CI: 0.869-0.954). The curve representing the performance of the nomogram fit in well with that representing a perfect prediction by the calibration plot. Decision curve analysis indicated that the nomogram was clinically useful for predicting DIED in the type 2 DM patients at the possibility threshold of 6% to 93%.A nomogram was preliminarily developed for predicting the risk of DIED in type 2 DM patients with respect to the seven independent influencing factors, including the duration of DM, status of c-IMT, DR, DKD, LDL-C, RDW, and Fbg.

Background The nematode worm, Caenorhabditis elegans, is a saprophytic species that has been emerging as a standard model organism since the early 1960s. This species is useful in numerous fields, including developmental biology, neurobiology, and ageing. A high-quality comprehensive molecular interaction network is needed to facilitate molecular mechanism studies in C. elegans. Results We present the predicted functional interactome of Caenorhabditis elegans (FIC), which integrates functional association data from 10 public databases to infer functional gene interactions on diverse functional perspectives. In this work, FIC includes 108,550 putative functional associations with balanced sensitivity and specificity, which are expected to cover 21.42% of all C. elegans protein interactions, and 29.25% of these associations may represent protein interactions. Based on FIC, we developed a gene set linkage analysis (GSLA) web tool to interpret potential functional impacts from a set of differentially expressed genes observed in transcriptome analyses. Conclusion We present the predicted C. elegans interactome database FIC, which is a high-quality database of predicted functional interactions among genes. The functional interactions in FIC serve as a good reference interactome for GSLA to annotate differentially expressed genes for their potential functional impacts. In a case study, the FIC/GSLA system shows more comprehensive and concise annotations compared to other widely used gene set annotation tools, including PANTHER and DAVID. FIC and its associated GSLA are available at the website http://worm.biomedtzc.cn.

The aim of this study is to explore the feasibility of using a non-sedation protocol for the evaluation of neonatal congenital heart disease by using 16-cm wide-detector CT with a low radiation dose. Thirty-four neonates (group 1) were enrolled to undergo cardiac CT without sedation between August 2018 and March 2019. The control group (group 2) comprising 20 inpatient neonates was sedated. Cardiac CT was performed using 16-cm area detector 320-row CT with free breathing and prospective ECG-triggering scan mode. The examination completion time, radiation dose, and image quality were compared between the groups. The results of cardiac CT for patients in group 1 who underwent surgery were compared with surgical findings. Intergroup differences in body weight, age, examination completion time, radiation dose, and image quality evaluation were not significant. There was no significant difference in oxygen saturation before and after the examination in group 1. In all, 98 separate cardiovascular abnormalities in 27 group 1 patients were confirmed using surgical reports. The overall sensitivity, specificity, positive predictive value, and negative predictive value of cardiac CT were 94.90%, 100.0%, 100.0%, and 98.53%. The non-sedation protocol can be applied in neonates with congenital heart disease by using 16-cm wide-detector CT with a low radiation dose. Based on the image quality obtained, non-sedative examination did not extend the examination completion time and helped avoid the possible side effects of sedative drugs.

Background Alzheimer’s disease (AD) is characterized by progressive memory loss and cognitive impairment. The aggregation of amyloid β (Aβ) and hyperphosphorylated tau protein are two major pathological features of AD. Nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase, NOX) has been indicated in Aβ pathology; however, whether and how it affects tau pathology are not yet clear. Methods The role of NOX2 in cognitive function, amyloid plaque formation, and tau hyperphosphorylation were examined in APP/PS1 transgenic mice mated with p47phox-deficient mice (with deletion of the gene of neutrophil cytosolic factor 1, Ncf1) and/or in p47phox-deficient mice receiving intracerebroventricular (ICV) injection of streptozotocin (STZ). The cognitive and non-cognitive functions in these mice were assessed by Morris water maze, Rotarod test, open field, and elevated plus maze. Aβ levels, amyloid plaques, p47phox expression, and astrocyte activation were evaluated using immunofluorescence staining, ELISA, and/or Western blotting. Cultured primary neuronal cells were treated with okadaic acid or conditioned media (CM) from high glucose-stimulated primary astrocytes. The alteration in tau pathology was determined using Western blotting and immunofluorescence staining. Results Deletion of the gene coding for p47phox, the organizer subunit of NOX2, significantly attenuated cognitive impairment and tau pathology in these mice. p47phox deficiency decreased the activation of astrocytes but had no effect on Aβ levels and amyloid plaque formation in the brains of aged APP/PS1 mice, which displayed markedly increased expression of p47phox in neurons and astrocytes. Cell culture studies found that neuronal p47phox deletion attenuated okadaic acid-induced tau hyperphosphorylation at specific sites in primary cultures of neurons. CM from high glucose-treated WT astrocytes increased tau hyperphosphorylation in primary neurons, whereas this effect was absent from p47phox-deficient astrocytes. Conclusions These results suggest that p47phox is associated with cognitive function and tau pathology in AD. p47phox expressed in neurons contributes to tau hyperphosphorylation directly, while p47phox in astrocytes affect tau hyperphosphorylation by activating astrocytes indirectly. Our results provide new insights into the role of NOX2 in AD and indicate that targeted inhibition of p47phox may be a new strategy for the treatment of AD.

Coronin 2A (CORO2A) is a novel component of the N-CoR (nuclear receptor co-repressor) complex. Abnormal CORO2A expression is associated with carcinogenesis. We used databases from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), and analyzed CORO2A expression and gene regulation networks in breast cancer. Expression was analyzed using GEO and TCGA database and further validated in breast cancer samples collected in our clinic. The prognostic value of CORO2A was explored by using the Kaplan–Meier survival analysis and Cox proportional hazards regression analysis. LinkedOmics was used to identify coexpressed genes associated with CORO2A. After analyzing the intersection of coexpressed genes correlated with CORO2A and differentially expressed genes after CORO2A silencing, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses of the intersecting genes were conducted by using FunRich software. Transwell assays were performed in breast cancer cells to determine the effect of CORO2A on cell migration. MTS, colony formation, and cell cycle distribution assays were performed in breast cancer cells to determine the effect of CORO2A on cell proliferation. Gene enrichment analysis was employed to explore the target networks of transcription factors and miRNAs. We found that CORO2A was upregulated and that the elevated expression of CORO2A was associated with poor overall survival (OS) and relapse-free survival (RFS) in TNBC patients. Further bioinformatics analysis of public sequencing data and our own RNA-Seq data revealed that CORO2A was probably involved in the epithelial-to-mesenchymal transition process and might have a significant effect on the migration of breast cancer cells, which might be mediated via pathways involving several miRNAs and MYC transcription factors. Functionally, the knockdown of CORO2A inhibited cell migration, decreased viability, and colony formation and induced cell cycle arrest in the G0/G1 phase in breast cancer cells. These results demonstrate that bioinformatics-based analysis efficiently reveals information about CORO2A expression and its potential regulatory networks in breast cancer, laying a foundation for further mechanistic research on the role of CORO2A in carcinogenesis. Moreover, CORO2A promotes the migration and proliferation of breast cancer cells and may have an important function in breast cancer progression. CORO2A is a potential prognostic predictor for TNBC patients. Targeting CORO2A may provide promising therapy strategies for breast cancer treatment.

Aim: The present study aimed to assess the association between IGF2/H19 genetic variants and susceptibility to platinum-based chemotherapy in epithelial ovarian cancer (EOC). Methods: A total of 43 platinum-resistant (PR) and 138 platinum-sensitive (PS) EOC patients were recruited in our study. 21 polymorphisms in IGF2/H19 locus were genotyped by Sequenom MassARRAY assay. Results: The frequencies of GG genotype in both rs3842761(C/G) and rs4244809(A/G) were significantly lower in PR group compared with those in PS group (9.76 vs 23.36%, p = 0.049; 9.76 vs 26.09%, p = 0.045; respectively). Compared with the AA genotype, rs4244809 GG genotype was associated with significantly reduced risk of platinum resistance (adjusted OR: 0.30; 95% CI: 0.10–0.91; p = 0.033). Further stratified analyses revealed that the SNPs of rs3842761 and rs4244809 were greatly related to PR risk in FIGO stage III–IV (rs3842761GG/CC+CG: adjusted OR: 0.15; 95% CI: 0.02–1.21; rs4244809 GG/AA+AG: adjusted OR: 0.24; 95% CI: 0.07–0.84; respectively) and serous adenocarcinoma subgroups (rs3842761 GG/CC+CG: adjusted OR: 0.21; 95% CI: 0.05–0.94; rs4244809 GG/AA+AG: adjusted OR: 0.19; 95% CI: 0.04–0.5; respectively), while rs7924316 polymorphism was associated with reduced risk of PR in serous adenocarcinoma subgroup as analyzed by a recessive model (rs7924316 GG/TT+TG: adjusted OR: 0.22; 95% CI: 0.05–0.98). In addition, both TCT haplotypes of rs3741206/rs3842761/rs7924316 and TC haplotype of rs3741206/rs3842761 were associated with elevated risk of PR (for the TCT haplotype of rs3741206/rs3842761/rs7924316: p = 0.049; OR: 1.69; 95% CI: 1.00–2.87; for the TC haplotype of rs3741206/rs3842761: p = 0.044; OR: 1.71; 95% CI: 1.01–2.88). Conclusion: These results suggest that polymorphisms in IGF2/H19 gene locus are associated with PR risk in EOC.

Breast cancer (BC) is the most malignant tumor in women. The molecular mechanisms underlying tumorigenesis still need to be further elucidated. It is necessary to investigate novel candidate genes involved in breast cancer progression and prognosis. In this study, we commit to explore candidate genes that associate with prognosis and therapy in BC by a comprehensive bioinformatic analysis. Four GEO datasets (GSE5764, GSE7904, GSE20711, and GSE29431) and the BC-related transcriptome data in TCGA database were downloaded and used to identify the differently expressed genes (DEGs). The function of DEGs was analyzed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enrichment analysis. The protein-protein interaction (PPI) network of DEGs was constructed to identify hub genes. Prognostic candidate genes were identified through survival analysis. In addition, potential therapeutic targets were identified by constructed gene-drug interaction network through Comparative Toxicogenomics Database. A total of 547 DEGs (302 up and 245 down) were identified. Three core-subnetwork and 25 hub genes were identified in PPI network. Seven genes (namely COL12A1, QPRT, MRPL13, KRT14, KRT15, LAMB3, and MYBPC1) were identified as crucial prognostic candidate genes, which significantly associated with breast cancer overall survival. Furthermore, two representative candidate genes (COL12A1 and LAMB3) were optionally chosen for verification by reverse transcription and quantitative real-time polymerase chain reaction (RT-PCR). What's more, the gene-drugs interaction analysis indicates several antitumor drugs that could affect the expression of these prognostic markers, such as doxorubicin, cisplatin, and tamoxifen. These results identified seven crucial candidate genes that may serve as prognosis biomarkers and novel therapeutic targets of breast cancer, which may facilitate further understanding the molecular pathogenesis and providing potential therapeutic strategies for BC.

Background: Traditional Chinese Medicine (TCM) prescriptions should be decided according to the TCM treatment principle, and the warming-yang or cooling-heat should be the guide of treatment principle outline. Methods: In order to identify which treatment principle, warming-yang or cooling-heat should be combined with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in non-small cell lung cancer (NSCLC), we combined the typical warming-yang drug, Shen-fu (SF), and the typical cooling-heat drug, Qing-kai-ling (QKL) with gefitinib in resistant NSCLC models. Results: The results demonstrated that QKL combined with gefitinib induced significantly increased cell viability inhibition and apoptosis in A549 cell line and significantly smaller tumor volume and lower tumor weight in H1975 xenograft transplanted nude mice. On the contrary, SF combined with gefitinib had significant antagonism effect on both cell viability inhibition and apoptosis in vitro , and on tumor weight in vivo . EGFR phosphorylation inhibition and the downstream PI3K/AKT and RAS/RAF/ERK pathway inhibition served an important role in the synergism effect between QKL and gefitinib in H1975 xenograft transplanted nude mice. Conclusions: The present study indicated that cooling-heat TCM treatment principle may reverse or delay NSCLC resistance to EGFR-TKIs, and combination of them warrants further study.
