RESUMO

OBJECTIVE: To investigate the effects of extracorporeal carbon dioxide removal (ECCO2R) combined with continuous renal replacement therapy (CRRT) on respiratory efficiency and diaphragm function in patients with acute respiratory distress syndrome (ARDS) received mechanical ventilation. METHODS: A prospective randomized controlled study was conducted. Sixty patients with mild to moderate ARDS admitted to the department of respiratory and critical care medicine of Henan Provincial People's Hospital from January 2019 to January 2021 were enrolled, and they were divided into observation group and control group according to the random number table method, with 30 cases in each group. All patients received antibiotics, anti-inflammatory, and mechanical ventilation therapy. On this basis, the observation group received ECCO2R and CRRT, while the control group received bedside CRRT. Baseline data including gender, age, etiology, acute physiology and chronic health evaluation II (APACHE II), etc., were recorded. Arterial blood gas analysis [including arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), and oxygenation index (PaO2/FiO2)] was performed at 12 hours and 24 hours during the treatment, and respiratory mechanics parameters [including tidal volume, respiratory rate, maximum expiratory pressure (MEP), and maximum inspiratory pressure (MIP)] were recorded, and rapid shallow breathing index (RSBI) was calculated. The levels of glutathione peroxidase (GSH-Px), malondialdehyde (MDA), and superoxide dismutase (SOD) in serum were detected by enzyme-linked immunosorbent assay (ELISA). Diaphragm thickness and diaphragm activity were measured by ultrasonography at 24 hours during the treatment. RESULTS: There were no significantly differences in age, gender, etiology, and APACHE II score between the two groups, indicating that the baseline data of the two groups were balanced and comparable. Compared with the 12 hours after treatment, the PaO2 and PaO2/FiO2 in the observation group significantly increased, PaCO2 significantly decreased, RSBI significantly decreased, MEP and MIP significantly increased, and serum GSH-Px and MDA significantly decreased, while SOD significantly increased at 24 hours during the treatment. In the control group, only PaCO2 significantly decreased. Compared with the control group, the PaCO2 significantly decreased in the observation group at 12 hours and 24 hours [mmHg (1 mmHg≈0.133 kPa): 55.05±7.57 vs. 59.49±6.95, 52.77±7.88 vs. 58.25±6.92, both P < 0.05], but no significantly differences in PaO2 and PaO2/FiO2. Compared with the control group, the observation group showed significant decreases in RSBI at 12 hours and 24 hours (times×min-1×L-1: 85.92±8.83 vs. 90.38±3.78, 75.73±3.86 vs. 90.05±3.66, both P < 0.05), significant increases in MEP and MIP [MEP (mmH2O, 1 mmH2O≈0.01 kPa): 86.64±5.99 vs. 83.88±4.18, 93.70±5.59 vs. 85.04±3.73; MIP (mmH2O): 44.19±6.66 vs. 41.17±3.13, 57.52±5.28 vs. 42.34±5.39, all P < 0.05], and significant decreases in serum GSH-Px and MDA [GSH-Px (mg/L): 78.52±8.72 vs. 82.10±3.37, 57.11±4.67 vs. 81.17±5.13; MDA (µmol/L): 7.84±1.97 vs. 8.71±0.83, 3.67±0.78 vs. 8.41±1.09, all P < 0.05], as well as a significant increase in SOD (U/L: 681.85±49.24 vs. 659.40±26.47, 782.32±40.56 vs. 676.65±51.97, both P < 0.05). Compared with the control group, the observation group showed significant increases in diaphragm thickness and diaphragm activity at 24 hours of treatment [diaphragm thickness (cm): 1.93±0.28 vs. 1.40±0.24, diaphragmatic thickening fraction: (0.22±0.04)% vs. (0.19±0.02)%, quiet breathing diaphragm displacement (cm): 1.42±0.13 vs. 1.36±0.06, deep breathing diaphragm displacement (cm): 5.11±0.75 vs. 2.64±0.59, all P < 0.05]. CONCLUSIONS: ECCO2R combined with CRRT can reduce work of breathing and oxidative stress levels in ARDS patients receiving non-invasive ventilation, and protect diaphragm function.

RESUMO

RATIONALE: Uterine torsion and giant leiomyoma are both rare diseases. Uterine torsion combined with giant leiomyoma with degeneration or infarction is easy to be misdiagnosed. We wrote this case to increase the accuracy and timeliness of medical staff's diagnosis and treatment of uterine fibroids combined with uterine torsion. PATIENT CONCERNS: We present a case of uterine torsion with degeneration and infarction of giant leiomyoma in a 66-year-old postmenopausal woman, who had a lump in her pelvis 10 years ago and suffered from acute abdominal pain half a day before hospitalization. DIAGNOSIS: The patient was considered as uterine torsion with huge abdominal mass by computed tomography and enhanced magnetic resonance imaging, and finally diagnosed as uterine torsion with giant leiomyoma through surgery and pathological examination. INTERVENTIONS AND OUTCOMES: The patient underwent exploratory laparotomy. In addition to the removal of huge uterine fibroids, the hysterectomy with double appendages was conducted. The histopathologic analysis showed "(Uterine tumor) leiomyoma with extensive edema, degeneration, infarction and calcification." The patient recovered well after operation and kept healthy in the follow-up to date. LESSONS: Although uterine torsion is extremely rare, early diagnosis and treatment are essential to prevent serious complications.

RESUMO

OBJECTIVE: Necroptosis is a form of programmed cell death identified irrelevant to caspases, which plays an important role in the tumorigenesis and development of cancer. MicroRNAs (miRNAs) are important regulators of both necroptosis and cancer. MATERIALS AND METHODS: Expression of sixteen necroptosis-associated miRNAs were analyzed in 546 endometrial cancer (EC) tissues and 33 paracancerous samples from the Cancer Genome Atlas (TCGA). Cox regression analysis was used to evaluate the correlations between miRNAs and overall survival. MiRNAs risk score (Mrs) and nomogram were established to assess the potential value of necroptosis-related miRNAs on prognosis. Expression of miRNA-148a-3p in endometrial cancer cells and endometrial epithelial cells was detected by quantitative real-time PCR (qRT-PCR). The targets genes of miR-148a-3p were predicted using miRDB, miRTarBase and TargetScan and the prognostic-related genes were screened. Immune infiltration analysis was conducted to explore the potential mechanism of these target genes. RESULTS: We identified fourteen differentially expressed miRNAs and selected seven miRNAs (miR-15a-5p, miR148a-3p, miR-7-5p, miR-141-3p, miR-200a-5p, miR-223-3p, miR-16-5p) for prognostic-model construction. The area under the curve (AUC) of receiver operating characteristic (ROC) curve for 1-, 2- and 5-year survival were 0.678, 0.652 and 0.656 respectively. Multivariate analysis revealed that the Mrs was an independent prognostic factor considering other risk factors (HR = 1.928, 95% CI = 1.072-3.467, P = 0.028). Among these miRNAs, miRNA-148a-3p was up-regulated in cancer tissues and cells, and Kaplan-Meier analysis showed its significance in overall survival (OS). The target genes, DNAJB4 and PRNP, were associated with poor prognosis and correlated with tumor immune infiltration. CONCLUSIONS: Our study constructed a novel necroptosis-associated miRNAs model for prognosis prediction, and DNAJB4 and PRNP may be therapeutic targets for EC.

RESUMO

This study intends to investigate the effects of DNA methyltransferase 3B (DNMT3B) and ten-eleven translocation 3 (TET3) on transforming growth factor-ß1 (TGF-ß1)-induced epithelial-mesenchymal transition (EMT) in ovarian cancer (OV) cells. According to the specific experiments, the cells were treated with TGF-ß1 for 48 h, and then the expressions of EMT-related proteins (E-cadherin, Vimentin and Snail), TET3 and DNMT3B were quantified by Western blot and quantitative reverse transcription polymerase chain reaction (qRT-PCR). Methprimer, methylation-specific PCR (MSP), bisulfite sequencing PCR (BSP) and chromatin immunoprecipitation (ChIP) were used to determine the regulation of DNMT3B on TET3 promoter. The impacts of DNMT3B and TET3 upon the EMT-related proteins and OV cell migration and invasion abilities were evaluated through the rescue experiments and the loss- and gain-of-function experiments. In line with the results, TGF-ß1 down-regulated TET3 and E-cadherin levels, up-regulated Vimentin and Snail levels, promoted migratory and invasive abilities, and increased methylation level of TET3 promoter in OV cells, which however were reversed by shDNMT3B. The binding of DNMT3B to TET3 promoter facilitated the methylation of TET3 promoter. Overexpressed TET3 inhibited the migratory and invasive abilities and EMT of OV cells, whereas shTET3 did the opposite. ShTET3 also offset the regulatory effects of shDNMT3B on EMT, migration and invasion of OV cells. To conclude, DNMT3B mitigates the suppression of TET3 on TGF-ß1-induced EMT in OV cells by methylating the promoter region of TET3.

RESUMO

RATIONALE: Granulocytic sarcoma (GS) is an uncommon extramedullary tumor, and involvement of the female reproductive system is very rare. PATIENT CONCERNS: We present a case of cervical GS in a 45-year-old woman who presented with repeated vaginal bleeding after sex for 1 month. DIAGNOSIS: The patient was diagnosed with cervical GS mainly based on pathological immunohistochemical examination and further progressed to acute myeloid leukemia (AML) based on bone marrow puncture and cytogenetic analysis. INTERVENTIONS AND OUTCOMES: The patient underwent hysterectomy and bilateral adnexectomy, and subsequently received AML-type chemotherapy. She relapsed 3 months after therapy and progressed to AML. The patient was then treated with chemotherapy with cytosine arabinoside and idarubicin again and achieved complete remission after 1 cycle. Currently, she is still receiving therapy combined with cytosine arabinoside and idarubicin, and has been alive for 13 months. LESSONS: Although GS of the reproductive system is rare, it should be included in the differential diagnosis of gynecological neoplasms and should be treated with AML-type chemotherapy protocols.

RESUMO

The current study set out to elucidate the function of epigallocatechin gallate (EGCG) against peritoneal fibrosis in peritoneal dialysis (PD) patients. Firstly, human peritoneal mesothelial cells (HPMCs) were pretreated with 0, 12.5, 25, 50 or 100µmol/L EGCG. Epithelial-mesenchymal transition (EMT) models were induced by advanced glycation end products (AGEs). Untreated-cells were regarded as the blank control group. Changes in proliferation and migration were analyzed by MTT assay and scratch test and levels of HPMC epithelial and interstitial molecular marker proteins were measured by Western blot assay and immunofluorescence, while trans-endothelial resistance was assessed using an epithelial trans membrane cell resistance meter. Inhibition rates of HPMCs, migration numbers and the levels of Snail, E-cadherin, CK and ZO-1 were all decreased, while the levels of α-SMA and FSP1 and trans cellular resistance values were increased in treatment groups (P<0.05). With the increase of EGCG concentrations, HPMCs growth inhibition rates and migration numbers, the levels of α-SMA and FSP1 and TER values were decreased and the levels of Snail, E-cadherin, CK and ZO-1 were enhanced (P<0.05). Overall, the current study highlights that EGCG effectively inhibits the proliferation and migration of HPMCs, increases permeability, suppresses EMT and ultimately delays peritoneal fibrosis.

RESUMO

To investigate the sleep quality and mental health status of healthcare professionals during the outbreak of coronavirus disease 2019 (COVID-19) in order to promote timely intervention and treatment. An Questionnaire Star of WeChat online survey was conducted at Hwamei Hospital, University of Chinese Academy of Sciences, NingBo, China. The questionnaire consisted of two parts including sociodemographic characteristics, and the Pittsburgh Sleep Quality Index (PSQI), the Generalized Anxiety Disorder (GAD-7) scale, a depression screening scale (Patient Health Questionnaire-9 [PHQ-9]) so as to investigate the sleep quality and mental health status of healthcare professionals during the outbreak of COVID-19.The data were analyzed with the t-test, χ2 test, one-way analysis of variance (ANOVA) and Pearson correlation, P < 0.05 was considered statistically significant. The mean score of PSQI is 5.8 ± 3.7 and the incidence of sleep disorders was 28.8% among the healthcare professionals and was related to occupation, title, education level, role and some underlying diseases. The positive rates for anxiety and depression among the healthcare professionals were 33.2% and 39.4% according to the GAD-7 and PHQ-9. Mental health status was related to occupation, education level, role and some underlying diseases. During the COVID-19 outbreak, sleep quality was significantly correlated with anxiety and depression among the healthcare professionals. The incidences of sleep disorder, anxiety and depression among healthcare professionals have been high. Furthermore, these disorders are interrelated and require timely intervention and treatment.

RESUMO

AIM: This study aims to investigate the safety and efficacy of chemotherapy in ovarian cancer patients in pregnancy. METHODS: In this study, eligible studies were searched on PubMed, Embase, and Cochrane Library databases up to December 31, 2020. Data were calculated and presented by frequency and percentage, mean ± standard deviation (SD), and median (range), respectively. Kaplan-Meier survival analysis was performed to estimate overall survival (OS) and progression-free survival (PFS). RESULTS: Finally, 34 studies including 40 ovarian cancer cases receiving chemotherapy during pregnancy were included. All 40 patients received chemotherapy during pregnancy. During the follow-up, seven of 37 (18.9%) women had a relapse and four of them (4/7, 57.1%) died of recurrence. Survival analysis failed to reach median OS and PFS within the follow-up (range 3-72 months). Better OS and PFS after chemotherapy in pregnancy were obtained in women with early-stage ovarian cancer (I) compared with those with advanced stage (III-IV). Neither OS nor FS differed between women treated with multi-drugs and those with monotherapy. Forty-one newborns were delivered from 40 pregnant women. Thirty-four (34/41, 82.9%) were completely healthy at birth and the end of follow-up (range 0.18-160 months). However, one newborn died 5 days after birth due to multiple congenital malformations, and another one developed Tourette's syndrome, aphasia, Asperger's syndrome as well as speech delay. CONCLUSIONS: This meta-analysis first reveals the efficacy and safety of chemotherapy for ovarian cancer during pregnancy, especially for early-stage patients. Cisplatin or carboplatin is suggested to be used as monotherapy to reduce adverse effects.

RESUMO

PURPOSE: China was affected by an outbreak of coronavirus disease 2019 (COVID-19) in 2019-2020. Research data are needed to develop evidence-driven strategies to reduce the adverse psychological and occupational impacts on healthcare workers (HCWs). METHODS: From March 1, 2020, to March 8, 2020, 946 HCWs in China completed a survey consist of sociodemographic data, precautionary measures against COVID-19, and concerns about COVID-19. Self-administered questionnaire were collected to assess psychological and occupational adverse outcomes of HCWs. Multivariable logistic regression analysis was performed to identify factors associated with the outcomes. RESULTS: A total of 55.0%, 56.0% and 48.3% of the HCWs experienced burnout, psychological distress and posttraumatic stress, respectively. A total of seven factors were independently associated with burnout: good health status (OR 0.51, 95% CI 0.36-0.71), fear of contagion (OR 1.31, 95% CI 1.003-1.79), avoiding contact with children (OR 1.40, 95% CI 1.03-1.91), enough staff support at the workplace (OR 0.59, 95% CI 0.38-0.92), having to work overtime (OR 1.37, 95% CI 1.03-1.83), maladaptive coping (OR 3.28, 95% CI 2.42-4.45) and adaptive coping (OR 0.47, 95% CI 0.35-0.62). A total of 11 factors were independently associated with high psychological distress: having one child (OR 0.54, 95% CI 0.38-0.77), good health status (OR 0.57, 95% CI 0.39-0.83), alcohol abuse (OR 1.51, 95% CI 1.02-2.25), thinking the epidemic would continue for quite a long time (OR 1.59, 95% CI 1.08-2.34), wearing extra-work clothes (OR 1.51, 95% CI 1.06-2.15),effective protective equipment (OR 0.45, 95% CI 0.22-0.90), enough staff support at the workplace (OR 0.55, 95% CI 0.34-0.89), unable to take care of families (OR 1.99, 95% CI 1.42-2.78), economic losses (OR 1.62, 95% CI 1.14-2.31), maladaptive coping (OR 6.88, 95% CI 4.75-9.97),and adaptive coping (OR 0.29, 95% CI 0.21-0.41). These factors were independently associated with posttraumatic stress: living with the elderly (OR 1.46, 95% CI 1.04-2.05), alcohol abuse (OR 1.41, 95% CI 1.002-1.98), working at a 3A hospital(OR 0.66, 95% CI 0.49-0.88), acquaintances confirmed COVID-19 (OR 2.14, 95% CI 1.20-3.84), fear of contagion (OR 1.87, 95% CI 1.40-2.50), believing they would survive if infected (OR 0.63, 95% CI 0.46-0.86), self-disinfected after arriving home (OR 1.43, 95% CI 1.01-2.02), interpersonal isolation (OR 1.65, 95% CI 1.21-2.26), unable to take care of families (OR 1.41, 95% CI 1.05-1.88) and maladaptive coping (OR 3.09, 95% CI 2.32-4.11). CONCLUSION: The variance in adverse outcomes was explained by the effect of various factors, which will help policymakers better prepare for subsequent potential outbreaks of COVID-19.

RESUMO

BACKGROUND: Although OIP5-AS1 has been characterized as an oncogenic lncRNA in many types of cancer, its role and underlying mechanism in ovarian carcinoma (OC) remains unknown. This study aimed to investigate the role of OIP5-AS1 in OC. METHODS: OC tissues and non-tumor tissues (ovary tissues within 3 cm around tumors) were collected from 58 OC patients (age range 36 to 67 years old, mean age 51.4 ± 5.9 years old). The expression of OIP5-AS1 and snail in paired tissues were determined by RT-qPCR. The interaction between OIP5-AS1 and miR-34a was predicted by IntaRNA2.0 and confirmed by dual luciferase reporter assay. The effects of overexpression of OIP5-AS1 and miR-34a on the expression of snail were analyzed by RT-qPCR and Western blotting. Cell invasion and migration were analyzed by Transwell assay. RESULTS: We observed that the expression of OIP5-AS1 and snail was upregulated and positively correlated with each other in OC. RNA-RNA interaction analysis showed that OIP5-AS1 might sponge miR-34a. In OC cells, overexpression of OIP5-AS1 resulted in the upregulated expression of snail, while overexpression of miR-34a downregulated the expression of snail. In addition, overexpression of miR-34a reduced the effects of overexpression of OIP5-AS1 on the expression of snail. In cell invasion and migration assay, overexpression of OIP5-AS1 and snail resulted in increased OC cell invasion and migration, while overexpression of miR-34a decreased OC cell invasion and migration. Moreover, overexpression of miR-34a attenuated the effects of OIP5-AS1 overexpression on OC cell invasion and migration. CONCLUSIONS: Therefore, OIP5-AS1 may upregulate snail expression in OC by sponging miR-34a to promote OC cell invasion and migration.

RESUMO

BACKGROUND: Epithelial ovarian cancer (EOC) is the majority ovarian cancer (OC) type with a poor prognosis. This present study aimed to investigate potential prognostic factors including albumin-to-fibrinogen ratio (AFR) for advanced EOC patients with neoadjuvant chemotherapy (NAC) followed by debulking surgery. METHODS: A total of 313 advanced EOC patients with NAC followed by debulking surgery from 2010 to 2017 were enrolled. The predictive value of AFR for the overall survival (OS) was evaluated by receiver operating characteristic (ROC) curve analysis. The univariate and multivariate Cox proportional hazards regression analyses were applied to investigate prognostic factors for advanced EOC patients. The association between preoperative AFR and progression free survival (PFS) or OS was determined via the Kaplan-Meier method using log-rank test. RESULTS: The ROC curve analysis showed that the cutoff value of preoperative AFR in predicting OS was determined to be 7.78 with an area under the curve (AUC) of 0.773 (P < 0.001). Chemotherapy resistance, preoperative CA125 and AFR were independent risk factors for PFS in advanced EOC patients. Furthermore, chemotherapy resistance, residual tumor and AFR were significant risk factors for OS by multivariate Cox analysis. A low preoperative AFR (≤7.78) was significantly associated with a worse PFS and OS via the Kaplan-Meier method by log-rank test (P < 0.001). CONCLUSIONS: A low preoperative AFR was an independent risk factor for PFS and OS in advanced EOC patients with NAC followed by debulking surgery.

RESUMO

BACKGROUND/AIMS: We aim to obtain a probiotic strain from Lactobacillus bulgaricus by testing its capability to decompose uremic toxins to provide new intestinal bacteria for the treatment of chronic renal failure. METHODS: Original L. bulgaricus was cultured with the serum of uremic patients and then mutated by physical (ultraviolet) and chemical (diethyl sulfate) methods repeatedly. Using creatinine decomposition rate as an observed index, we selected the best strains which decreased the most concentration of the creatinine. We then tested its ability to decompose urea, uric acid, serum phosphate, parathyroid hormone, and homocysteine and its genetic stability. RESULTS: After inductive and mutagenic treatment, DUC3-17 was selected. Its decomposition rate of creatinine, urea nitrogen, uric acid, phosphorus, parathyroid hormone, and homocysteine were 17.23%, 36.02%, 9.84%, 15.73%, 78.26%, and 12.69%, respectively. The degrading capacity was sustained over five generations. CONCLUSIONS: After directional induction and compound mutation, L. bulgaricus has greater capacity to decompose uremic toxins, with a stable inheritance.

RESUMO

OBJECTIVE: To investigate the effect of Shenfushu granule (SFSG) and atropine treatment on microvessels of the kidney and intestine after chronic renal failure (CRF) induced by 5/6 nephrectomy. METHODS: Sprague Dawley rats were randomly divided into a sham group, a model group, an SFSG group, and an SFSG + atropine group. SFSG was administered daily 1 week after inducing CRF. Rats were sacrificed at the end of the eighth week. Urinary protein and stool and serum urea nitrogen (UN) and creatinine (Cr) levels were assessed. Hematoxylin and eosin and periodic acid-Schiff staining of the kidney and examination of the vascular endothelial growth factor (VEGF) and microvessel density (MVD) levels in kidney and intestine were performed. RESULTS: The Cr and UN levels were significantly increased in blood and stool of the model group. SFSG significantly improved renal function, and the protective effects were further enhanced with the addition of atropine. Glomerular sclerosis, tubulointerstitial fibrosis, and microvessel loss were observed in CRF rats, and these pathological changes were ameliorated in the two treatment groups (p < 0.05), especially in the SFSG + atropine group. The expression of VEGF and MVD was decreased in the CRF rats compared with the sham group. SFSG treatment increased the expression of these proteins and reversed the degree of microvessel loss, glomerular sclerosis, and tubulointerstitial fibrosis (p < 0.05). Co-treatment with atropine enhanced these effects. CONCLUSIONS: SFSG alleviated renal function, upregulated the expression of VEGF and MVD in the kidney and intestine, and attenuated the degree of microvessel loss, glomerular sclerosis, and tubulointerstitial fibrosis in the early stages of CRF in rats, and addition of atropine enhanced these effects.
