RESUMEN

Phase-modulator-generated laser for Raman transition is widely used in atom gravimeters to simplify a system and improve robustness. However, the induced additional sidebands (ASBs) lead to systematic errors in gravity measurement. This work presents a novel, to our knowledge, method to generate an optical single-sideband (OSSB) laser for Raman transition through phase modulation based on a Faraday anomalous dispersion atomic filter (FADOF). The experimental result indicates that it can reduce the additional sidebands with a signal-to-noise ratio (SNR, the intensity ratio of carrier and unwanted sidebands) of better than 50 dB, and the phase shift caused by ASBs is demonstrated to be effectively suppressed from 358.8 to 2.2 mrad. Furthermore, this system has already been applied on an atom gravimeter to achieve a primary gravity measurement. It shows that the FADOF-based Raman laser system is a new scheme for a compact atom absolute gravimeter.

RESUMEN

Objective: To investigate the performance of multiparametric magnetic resonance imaging (MRI)-based radiomics models in differentiating early stage of cervical cancer (Stage I-IIa vs. IIb-IV). Methods: One hundred patients with cervical cancer who underwent preoperative MRI between June 2020 and March 2022 were retrospectively enrolled. Training (n = 70) and testing cohorts (n = 30) were assigned by stratified random sampling. The clinical and pathological features, including age, histological subtypes, tumor grades, and node status, were compared between the two cohorts by t-test or chi-square test. Radiomics features were extracted from each volume of interest (VOI) on T2-weighted images (T2WI) and apparent diffusion coefficient (ADC) maps. The data balance of the training cohort was resampled by synthesizing minority oversampling techniques. Subsequently, the adiomics signatures were constructed by the least absolute shrinkage and selection operator algorithm and minimum-redundancy maximum-relevance with 10-fold cross-validation. Logistic regression was applied to predict the cervical cancer stages (low [I-IIa]) and (high [IIb-IV] FIGO stages). The receiver operating characteristic curve (area under the curve [AUC]) and decision curve analysis were used to assess the performance of the radiomics model. Results: The characteristics of age, histological subtypes, tumor grades, and node status were not significantly different between the low [I-IIa] and high [IIb-IV] FIGO stages (p > 0.05 for both the training and test cohorts). Three models based on T2WI, ADC maps, and the combined were developed based on six radiomics features from T2WI and three radiomics features from ADC maps, with AUCs of 0.855 (95% confidence interval [CI], 0.777-0.934) and 0.823 (95% CI, 0.727-0.919), 0.861 (95% CI, 0.785-0.936) and 0.81 (95% CI, 0.701-0.918), 0.934 (95% CI, 0.884-0.984) and 0.902 (95% CI, 0.832-0.972) in the training and test cohorts. Conclusion: The radiomics models combined T2W and ADC maps had good predictive performance in differentiating the early stage from locally advanced cervical cancer.

RESUMEN

Objective: To evaluate the influence of Ixeris sonchifolia Hance injection combined with isosorbide mononitrate in patients with coronary heart disease (CHD) and diabetes. Methods: 60 patients with CHD and diabetes mellitus admitted to our hospital between January 2019 and June 2020 were recruited and assigned via the random number table method at a ratio of 1 : 1 to receive either isosorbide mononitrate treatment (control group) or Ixeris sonchifolia Hance injection plus isosorbide mononitrate treatment (observation group). Outcome measures included left ventricular end diastolic pressure (LVEDP), left ventricular end systolic volume (LVESV), left ventricular function (LVEF), brain natriuretic peptide (BNP), and the total treatment efficiency. Results: The two groups had similar LVEDP, LVESV, and LVEF before treatment (p > 0.05). After treatment, the LVEDP and LVESV of the two groups declined (p < 0.05), whereas LVEF increased (p < 0.05), with lower LVEDP and LVESV and higher LVEF in the observation group than in the control group (p < 0.05). Before treatment, there were no significant differences in the BNP levels between the two groups (p > 0.05). After treatment, the observation group had a more significant reduction in the BNP levels versus the observation group (p < 0.05). The observation group showed a higher treatment efficacy than the control group (p < 0.05). Conclusion: Ixeris sonchifolia Hance plus isosorbide mononitrate may offer a viable alternative in the treatment of patients with CHD and diabetes mellitus. Future trials are, however, required prior to clinical promotion.

RESUMEN

INTRODUCTION: Enhanced recovery after surgery (ERAS) guidelines strongly recommends that patients be in early postoperative ambulation within 24 hours. This study aims to assess the effectiveness and safety of the self-fatigue assessment method to guide patients' early postoperative ambulation. METHODS AND ANALYSIS: This is a single-centre, randomised, open, parallel-controlled trial. Five hundred and fifty-two patients who meet the inclusion criteria for gynaecological oncology surgery are randomly assigned in a 1:1 ratio to either a self-fatigue assessment group (study group) or a fixed activity distance assessment group (control group). The fixed activity distance group adopts a fixed early postoperative ambulation distance to guide the patient's activity, while the self-fatigue assessment group uses the Borg Exercise Scale to assess the patient's fatigue and stops activity when the fatigue level reaches 5-6. The primary outcome measure is the time to first postoperative flatus. Secondary outcome measures are the time to first bowel movement, the incidence of moderate to severe bloating, the incidence of bowel obstruction or venous thromboembolism, the incidence of adverse events (nausea, vomiting, dizziness), patient satisfaction, sleep quality scores, patient compliance with activities, hospital costs and days in hospital. ETHICS AND DISSEMINATION: This study was approved by the Independent Ethics Committee of Xiangyang Central Hospital affiliated with Hubei University of Arts and Sciences and registered with the China Clinical Trials Registry in May 2021. The results of the trial will be disseminated through open access peer-reviewed journals and abstracts will be submitted to relevant national and international conferences. TRIAL REGISTRATION NUMBER: CTR2100046035.

RESUMEN

INTRODUCTION: Chemoresistance remains the main cause of treatment failure in cervical cancer and novel therapeutic strategies are required. Cobimetinib, a potent yet selective inhibitor of MEK1 and 2, is currently used to treat melanoma clinically. In this work, we identified cobimetinib as a promising candidate for treating cervical cancer. METHODS: The in vitro and in vivo efficacies of cobimetinib were examined using cervical cancer cell cultures and xenograft mouse model. Its combination with paclitaxel was analyzed using the combination index. Immunoblotting was performed on MAPK and ERK pathways. RESULTS: Cobimetinib displays a potent anti-cervical cancer activity in a panel of cell lines regardless of cellular origin and HPV presence, and its combination with paclitaxel is synergistic in inhibiting cervical cancer cells. This is achieved by the growth inhibition and caspase-dependent apoptosis induction, through inhibiting MAPK/ERK activation. In addition, paclitaxel activates ERK in cervical cancer cells, and this can be reversed by cobimetinib. We finally confirm the efficacy of cobimetinib alone and its combination with paclitaxel in the cervical cancer xenograft mouse model. DISCUSSION/CONCLUSION: Our preclinical findings will accelerate the initialization of clinical trials to use combination of cobimetinib and paclitaxel for treating cervical cancer. Our work also emphasizes the therapeutic value of targeting MAPK/ERK to overcome chemoresistance in cervical cancer.

RESUMEN

Low P availability is a vital constraint for nodulation and efficient N2 fixation of legume, including soybean. To elucidate the mechanisms involved in nodule adaption to low P availability under legume/cereal intercropping systems, two experiments consisting of three cropping patterns (monocropped soybean, monocropped maize, soybean/maize intercropping) were studied under both sufficient- and deficient-P levels. Our results demonstrated that intercropped soybean with maize showed a higher nodulation and N2 fixation efficiency under low P availability than monocropped soybean as evidenced by improvement in the number, dry weight and nitrogenase activity of nodules. These differences might be attributed to increase in P level in intercropping-induced nodules under low P supply, which was caused by the elevated activities of phytase and acid phosphatases in intercropping-induced nodules. Additionally, the enhanced expression of phytase gene in nodules supplied with deficient P level coincided with an increase in phytase and acid phosphatase activities. Our results revealed a mechanism for how intercropped maize stimulated nodulation and N2 fixation of soybean under P deficient environments, where enhanced synthesis of phytase and acid phosphatases in intercropping-induced nodules, and stimulated nodulation and N2 fixation.

RESUMEN

Cervical cancer (CC) is one of the most common malignancies in females, with high prevalence and mortality globally. Despite advances in diagnosis and therapeutic strategies developed in recent years, CC is still a major health burden worldwide. The molecular mechanisms underlying the development of CC need to be understood. In this study, we aimed to demonstrate the role of lncRNA SNHG15 in CC progression. Using qRT-PCR, we determined that lncRNA SNHG15 is highly expressed in CC tumor tissues and cells. lncRNA SNHG15 knockdown also reduces the tumorigenic properties of CC in vitro, as determined using the MTT, EdU, flow cytometry, and transwell assays. Using bioinformatics analysis, RNA pull-down, ChIP, and luciferase reporter assays, we verified the molecular mechanisms of lncRNA SNHG15 in CC progression and found that lncRNA SNHG15 expression in CC cells is transcriptionally regulated by SOX12; moreover, lncRNA SNHG15 promotes CC progression via the miR-4735-3p/HIF1a axis. This study can provide a potential target for CC diagnosis or therapeutic strategies in the future.

RESUMEN

A pot experiment was conducted to investigate the changes of root morphology and its relationship with P uptake under different P levels (0, 50 and 100 mg P2O5·kg-1, represented by P0, P50 and P100, respectively). The results showed that intercropping significantly changed root morphological parameters of both maize and soybean, and increased the root:shoot ratio in soybean under different P levels. Intercropping significantly increased root length, root surface area, root volume, and root dry weight of maize and soybean by 25.6%, 22.0%, 39.2%, 34.3% and 28.1%, 29.7%, 37.3%, 62.3%, respectively, but significantly decreased the average root diameter by 15.2% and 11.7% compared to corresponding monoculture. The phosphorus uptake equivalent ratio (LERP) was >1, showing P uptake advantage of intercropping and that the LERP were unaffected by P levels. The root morphological changes induced by intercropping were closely related to P uptake improvement. The increases of maize root surface area and soybean root length were the main mechanisms driving efficient P uptake in maize and soybean intercropping. Based on the regression equation, 10% increase of maize root surface area or soybean root length caused 5%-10% increase of phosphorus uptake. P uptake of intercropped maize was not declined under P50 level compared to that of monoculture supplied with P100 level. In conclusion, maize and soybean intercropping has the potential to maintain crop P uptake when reducing application of phosphate fertilizer.

RESUMEN

Discs large-associated protein 5 (DLGAP5) is a microtubule-associated protein and is reported to exert oncogenic role in tumorigenesis, including lung cancer and hepatocellular carcinoma. However, the prognostic value and biological function of DLGAP5 in ovarian cancer (OC) still remain unclear. The present study investigated the expression pattern of DLGAP5 by searching the Oncomine microarray database. The correlation between DLGAP5 and survival prognosis of OC patients was analyzed by the online tool KM-plotter. Knockdown of DLGAP5 was achieved by transfection with small interfering RNA targeting DLGAP5 in two OC cell lines (SKOV3 and CAOV3). Cell proliferation was assessed by Cell Counting Kit-8 assay and colony-formation assay. Flow cytometry was utilized to determine the effects of DLGAP5 on cell cycle distribution and apoptosis. The present study data showed that DLGAP5 was significantly upregulated in OC and its higher expression was associated with poor survival prognosis. Knockdown of DLGAP5 significantly suppressed cell proliferation, induced cell cycle G2/M phase arrest and apoptosis. Western blot analysis further demonstrated that DLGAP5 knockdown downregulated the expression of CDK1, Cyclin B1 and Bcl-2, but upregulated Bax expression. Collectively, these data demonstrate that DLGAP5 might be a promising prognostic therapeutic target for OC treatment.

RESUMEN

Long noncoding RNAs act essential regulators in cervical cancer progression. Our study aimed to investigate the underlying function and molecular mechanisms of LINC00657 in cervical cancer. QRT-PCR results indicated that LINC00657 was significantly decreased in cervical cancer. Gain-and loss-of-function experiments were performed in SiHa and HeLa. Functional assays demonstrated that LINC00657 inhibited cervical cancer cell growth, migration and invasion. Moreover, miR-20a-5p was confirmed as a target of LINC00657. Furthermore, miR-20a-5p promoted the development of cervical cancer via targeting RUNX3. DR5 acts as a vital promoter in activating NK cells and is a downstream target of RUNX3. We found that LINC00657 overexpression promoted the cytotoxic activity of NK cells via regulating RUNX3/DR5 axis. Therefore, LINC00657 suppressed cervical cancer progression via inducing miR-20a-5p/RUNX3/DR5 mediated NK cell tolerance. In conclusion, LINC00657 was identified as a novel tumor-suppressor in cervical cancer and could function as a potential therapeutic target for clinical treatment.

RESUMEN

AIM: Angong Niuhuang pill (ANP) is a traditional Chinese medicine (TCM) drug widely used for treating stroke. This study aimed to investigate the effect of ANP on respiratory nursing outcomes in chronic obstructive pulmonary disease (COPD) patients following cardiac surgery. METHODS: A total of 80 COPD patients following cardiac surgery were enrolled and randomized into the control group receiving routine postoperative nursing and ANP group additionally receiving ANP treatment for 3 days (n = 40 for both group). The frequency of back percussion, time of back percussion, amount of expectoration, arterial blood gas levels were compared between groups. RESULTS: Compared to the control group, the ANP group had a significantly shorter daily mean time of back percussion at day 3 (p = .036) and day 7 (p = .014). The daily mean amount of expectoration was higher at day3 (p = .018) but lower at day 7 (p = .043) in the ANP group than in the control group. In addition, the ANP group had significantly higher hemoglobin saturation (SpO2 ) and partial pressure of oxygen (PaO2 ) but lower partial pressure of carbon dioxide (PaCO2 ) at both day 3 and day 7 than the control group (all p < .05). Furthermore, the time of postoperative aerosol inhalations (p = .041), pulmonary infection rate (p = .025) and postoperative hospital stay (p = .036) were significantly reduced in the ANP group. The ANP group had significantly lower TCM symptom scores at day 3 and day 7 after surgery. CONCLUSION: These results suggested that ANP treatment can effectively promote the postoperative recovery and respiratory nursing outcomes in COPD patients following cardiac surgery.

RESUMEN

BACKGROUND: Evidence suggested that vaginal microbiome played a functional role in the progression of cervical lesions in female infected by HPV. This study aimed at evaluating the influence of common vaginal infection on the carcinogenicity of high risk HPV (hr-HPV). METHODS: From January 15, 2017 to December 31, 2017, 310,545 female aged at least 30 years old had been recruited for cervical cancer screening from 9 clinical research centers in Central China. All the recruited participants received hr-HPV genotyping for cervical cancer screening and vaginal microenvironment test by a high vaginal swab. Colposcopy-directed biopsy was recommended for female who were infected with HPV 16 and HPV 18, and other positive hr-HPV types through test had undertaken triage using liquid-based cytology, cases with the results ≥ ASCUS among them were referred to colposcopy directly, and cervical tissues were taken for pathology examination to make clear the presence or absence of other cervical lesions. RESULTS: Among 310,545 female, 6067 (1.95%) were tested with positive HPV 16 and HPV 18, 18,297 (5.89%) were tested with other positive hr-HPV genotypes, cervical intraepithelial neoplasia (CIN) 1, CIN 2, CIN 3 and invasive cervical cancer (ICC) were detected in 861 cases, 377 cases, 423 cases, and 77 cases, respectively. Candida albicans and Gardnerella were not associated with the detection of cervical lesions. Positive trichomonas vaginitis (TV) was correlated with hr-HPV infection (p < 0.0001). Co-infection with TV increased the risk of CIN 1 among female infected with hr-HPV (OR 1.18, 95% CI: 1.42-2.31). Co-infection with TV increased the risk of CIN 2-3 among female infected with HPV 16 (OR 1.71, 95% CI: 1.16-2.53). CONCLUSIONS: Co-infection of TV and HPV 16 is a significant factor for the detection of cervical lesions.

RESUMEN

Musk, the dried secretion from the preputial follicles of the male musk deer (genus Moschus), possesses various pharmacological activities and has been used extensively in traditional Chinese medicine for thousands of years. Muscone is the main active ingredient of musk and exerts pharmacological effects similar to those of musk. Although muscone was notably used to treat various disorders and diseases, such as neurological disorders, chronic inflammation and ischemia-reperfusion injury, most of the mechanisms of the pharmacological action of muscone remain unclear because of slow progress in research before the 21st century. In recent years, the pharmacological activities and mechanisms of muscone have been clarified. The present article summarizes the pharmacological and biological studies on cerebrovascular disease, cardiovascular disease, neurological effects, cancer and others and the associated mechanisms of the action of muscone to date.

RESUMEN

NEAT1 is an important tumor oncogenic gene in various tumors. Nevertheless, its involvement remains poorly studied in cervical cancer. Our study explored the functional mechanism of NEAT1 in cervical cancer. NEAT1 level in several cervical cancer cells was quantified and we found NEAT1 was greatly upregulated in vitro. NEAT1 knockdown inhibited cervical cancer development through repressing cell proliferation, colony formation, capacity of migration, and invasion and also inducing the apoptosis. For another, microRNA (miR)-133a was downregulated in cervical cancer cells and NEAT1 negatively modulated miR-133a expression. Subsequently, we validated that miR-133a functioned as a potential target of NEAT1. Meanwhile, SOX4 is abnormally expressed in various cancers. SOX4 was able to act as a downstream target of miR-133a and silencing of SOX4 can restrain cervical cancer progression. In addition, in vivo assays were conducted to prove the role of NEAT1/miR-133a/SOX4 axis in cervical cancer. These findings implied that NEAT1 served as a competing endogenous RNA to sponge miR-133a and regulate SOX4 in cervical cancer pathogenesis. To sum up, it was implied that NEAT1/miR-133a/SOX4 axis was involved in cervical cancer development.

RESUMEN

Long non-coding RNAs have been reported to play crucial roles in tumorigenesis including cervical cancer. LINC00037 has been identified as a significant regulator in several cancers. Our study was aimed to investigate the function of LINC00037 in cervical cancer progression. LINC00037 was significantly downregulated in human cervical cancer cells (HeLa, HCC94, HT-3, Caski, and SiHa cells) compared with the ectocervical epithelial cells (End1/E6E7 cells). Overexpression of LINC00037 was able to inhibit cervical cancer cell proliferation, induce cell apoptosis, and restrain the cell migration/invasion capacity. Reversely, knockdown of LINC00037 exhibited an opposite process in vitro. mTOR has been recognized as an atypical serine/threonine kinase that is involved in regulating significant cellular functions. In our present study, we observed that the mTOR signaling pathway was strongly activated in human cervical cancer cells. Meanwhile, upregulation of LINC00037 contributed to the inactivation of mTOR signaling whereas downregulation of LINC00037 activated the pathway. Subsequently, in vivo animal models using SiHa cells were established and we proved that LINC00037 repressed cervical cancer progression via targeting the mTOR signaling pathway. All these findings implied that LINC00037 could regulate cervical cancer pathogenesis via mTOR signaling. In conclusion, a novel role of LINC00037 was manifested in cervical cancer progression.

RESUMEN

Cervical cancer continues to be a major public health problem. Although long noncoding RNAs (lncRNAs) were involved in the initiation and progression of cancer, few studies focus on the lncRNAs in the cervical cancer. Here, we systematically studied the clinical information, transcriptome profiling, and methylation array data of cervical squamous cell carcinoma and endocervical adenocarcinoma that retrieved from genomic data commons (GDC). Compared with protein-coding genes, the expression levels of pseudogenes and lncRNAs were much lower. A total of 190 differentially expressed lncRNAs and 2,326 protein-coding genes were identified. Meanwhile, 269 differentially methylation regions (DMRs), where 16 lncRNAs were located, were figured out. Only one lncRNA, LINC00592, which was located in the DMRs, was also found differentially expressed. Several transcriptional regulation genes, such as ZNF20, ZNF441, ZNF573, and TMF1, were highly correlated with the expression of LINC00592, which illustrated its possible function on the transcription. Two microRNAs, which were both associated with tumor progression, can bind to LINC00592. Moreover, LINC00592 were also differentially expressed in other tumors. We proposed, with the help of various databases, that LINC00592 is a potential cancer-related lncRNA in cervical cancer and might activate the cancer progression through the regulation of transcription or structural integrity.

RESUMEN

Long non-coding RNAs (lncRNAs), which have little or no protein-coding capacity, caught a particular interest since their potential roles in the cancer paradigm. As the most common cancer in women, cervical squamous cell carcinoma remains one of the leading causes of deaths from cancer. However, limited evidence is available to determine the role of lncRNAs in the prognosis of cervical squamous cell carcinoma. In this study, we collected lncRNA expression profiling to identify prognosis related lncRNAs for cervical squamous cell carcinoma from TCGA database. In addition, we developed a 15-lncRNA signature based risk score to comprehensively assess the prognostic function of lncRNA. Furthermore, we performed a ROC analysis to identify the optimal cut-off point for classification risk level of the patients. Univariate Cox regression models were used to assess the association between lncRNAs and prognosis of patients with cervical squamous cell carcinoma. A 15-lncRNA based risk score was developed based on the Cox co-efficient of the individual lncRNAs. The prognostic value of this risk score was validated in the complete set and internal testing set. In summary, a 15-lncRNA expression signature (BAIAP2-AS1, RP11-203J24.8, LINC01133, RP1-7G5.6, RP11-147L13.15, SERHL, CTC-537E7.3, RP11-440L14.1, RP11-131N11.4, ILF3-AS1, RP11-80H18.4, RP11-1096G20.5, CTD-2192J16.26, RP11-621L6.3, and RP11-571M6.18) were identified and validated which can predict cervical cancer patient survival. The potential functions of this 15-lncRNA expression signature and individual lncRNAs as prognostic targets of cervical cancer were revealed by this study. Furthermore, these findings may have important implications in the understanding of the potential therapeutic method for the cervical squamous cell carcinoma patients.

RESUMEN

For the treatment of stage III/IV malignant melanoma (MM), a network meta-analysis (NMA) was conducted to compare the short and long-term efficacy of targeted therapy with single or double-drug regimens. All conducted randomized controlled trials (RCTs) searched from PubMed and Cochrane Library were included in the study for direct and indirect comparison for MM. The odds ratio (OR) and surface under the cumulative ranking curves (SUCRA) value of the targeted therapy with single or double-drug regimens for treatment of stage III/IV MM were also analyzed. To group the treatments according to their similarity with regards to both outcomes, cluster analyses were performed. Ultimately, 16 RCTs were incorporated for this NMA. The NMA revealed that the overall response rate (ORR) values of single-drug regimens (Vemurafenib [Vem], Dabrafenib [Dab], and Nivolumab [Niv]) were higher than those of Dacarbazine (Dac). Also the ORR values of double-drug regimens (Dab + Trametinib [Dab + Tra], Niv + Ipilimumab [Niv + Ipi], and Vem + Cobimetinib [Vem + Cob]) were moderately higher than those of Dac. The results of the SUCRA showed that short-term efficacy of single-drug regimens (Vem and Dab) were better, while the short-term efficacy of double-drug regimens (Dab + Tra and Vem + Cob) were relatively better. It was determined that Vem, Dab, and Niv might be the best choice in evaluating the treatment of stage III/IV MM among different single-drug targeted therapy regimens, while Dab + Tra, Niv + Ipi, and Vem + Cob might have better short-term efficacy among different double-drug targeted therapy regimens.
