RESUMO

Cardiometabolic diseases (CMDs) are major contributors to global mortality, emphasizing the critical need for novel therapeutic interventions. Hydrogen sulfide (H2S) has garnered enormous attention as a significant gasotransmitter with various physiological, pathophysiological, and pharmacological impacts within mammalian cardiometabolic systems. In addition to its roles in attenuating oxidative stress and inflammatory response, burgeoning research emphasizes the significance of H2S in regulating proteins via persulfidation, a well-known modification intricately associated with the pathogenesis of CMDs This review seeks to investigate recent updates on the physiological actions of endogenous H2S and the pharmacological roles of various H2S donors in addressing diverse aspects of CMDs across cellular, animal, and clinical studies. Of note, advanced methodologies including multi-omics, intestinal microflora analysis, organoid and single-cell sequencing techniques are gaining traction due to their ability to offer comprehensive insights into biomedical research. These emerging approaches hold promise in characterizing the pharmacological roles of H2S in health and diseases. We will critically assesse the current literatures to clarify the roles of H2S in diseases while also delineating the opportunities and challenges they present in H2S-based pharmacotherapy for CMDs. Significance Statement The comprehensive review covers recent developments in H2S biology and pharmacology in CMDs. Endogenous H2S and its donors show great promise for the management of CMDs by regulating numerous proteins and signaling pathways. The emergence of new technologies will considerably advance the pharmacological research and clinical translation of H2S.

RESUMO

Background: Mental health disorders in patients with multi-drug or rifampicin-resistant tuberculosis (MDR/RR-TB) receive consistent attention. Anxiety and depression can manifest and may impact disease progression in patients with MDR/RR-TB. Given the heightened stressors resulting from the COVID-19 pandemic, this scenario is even more concerning. Objective: To evaluate the prevalence of and risk factors associated with anxiety and depression among patients with MDR/RR-TB in southern China. Methods: A facility-based cross-sectional study was undertaken at Guangzhou Chest Hospital in southern China, encompassing a cohort of 219 patients undergoing outpatient and inpatient treatment for MDR/RR-TB. Anxiety and depressive symptoms were assessed using the 7-Item Generalized Anxiety Disorder (GAD-7) scale and Patient Health Questionnaire-9 (PHQ-9). The ramifications of anxiety and depression were examined using univariate and multivariate logistic regression analyses, with odds ratios (ORs) and age- and sex-adjusted ORs (AORs) employed to quantify their influence. All data underwent statistical analysis using SPSS 25.0, with statistical significance established at P < 0.05. Results: Two hundred and nineteen individuals with MDR/RR-TB were included in the study. The prevalence of anxiety and depression was 57.53% (n = 126) and 65.75% (n = 144), respectively, with 33.3% (n = 73) of the participants experiencing both conditions simultaneously. Multivariate logistic regression analysis revealed that an age of 20-40 years [anxiety AOR = 3.021, 95% confidence interval (CI): 1.240-7.360; depression AOR = 3.538, 95% CI: 1.219-10.268], disease stigma (anxiety AOR = 10.613, 95% CI: 2.966-37.975; depression AOR = 4.514, 95% CI: 2.051-10.108) and poor physical health (anxiety AOR = 7.636, 95% CI: 2.938-19.844; depression AOR = 6.190, 95% CI: 2.468-15.529) were significant risk factors for moderate levels of anxiety and depression. Conclusions: We found that individuals with MDR/RR-TB had an elevated risk of anxiety and depression. To decrease the likelihood of unfavorable treatment outcomes, it is imperative to carefully monitor the psychological wellbeing of patients with MDR/RR-TB and promptly address any detrimental psychiatric conditions.

RESUMO

BACKGROUND: Neutral cholesterol ester hydrolase 1 (NCEH1) plays a critical role in the regulation of cholesterol ester metabolism. Deficiency of NCHE1 accelerated atherosclerotic lesion formation in mice. Nonetheless, the role of NCEH1 in endothelial dysfunction associated with diabetes has not been explored. The present study sought to investigate whether NCEH1 improved endothelial function in diabetes, and the underlying mechanisms were explored. METHODS: The expression and activity of NCEH1 were determined in obese mice with high-fat diet (HFD) feeding, high glucose (HG)-induced mouse aortae or primary endothelial cells (ECs). Endothelium-dependent relaxation (EDR) in aortae response to acetylcholine (Ach) was measured. RESULTS: Results showed that the expression and activity of NCEH1 were lower in HFD-induced mouse aortae, HG-exposed mouse aortae ex vivo, and HG-incubated primary ECs. HG exposure reduced EDR in mouse aortae, which was exaggerated by endothelial-specific deficiency of NCEH1, whereas NCEH1 overexpression restored the impaired EDR. Similar results were observed in HFD mice. Mechanically, NCEH1 ameliorated the disrupted EDR by dissociating endothelial nitric oxide synthase (eNOS) from caveolin-1 (Cav-1), leading to eNOS activation and nitric oxide (NO) release. Moreover, interaction of NCEH1 with the E3 ubiquitin-protein ligase ZNRF1 led to the degradation of Cav-1 through the ubiquitination pathway. Silencing Cav-1 and upregulating ZNRF1 were sufficient to improve EDR of diabetic aortas, while overexpression of Cav-1 and downregulation of ZNRF1 abolished the effects of NCEH1 on endothelial function in diabetes. Thus, NCEH1 preserves endothelial function through increasing NO bioavailability secondary to the disruption of the Cav-1/eNOS complex in the endothelium of diabetic mice, depending on ZNRF1-induced ubiquitination of Cav-1. CONCLUSIONS: NCEH1 may be a promising candidate for the prevention and treatment of vascular complications of diabetes.

RESUMO

OBJECTIVE To provide reference for safe drug use in clinic by mining the adverse drug events (ADE) of 3 kinds of anti-influenza A virus drugs (oseltamivir, zanamivir, baloxavir marboxil). METHODS The ADE data of oseltamivir, zanamivir and baloxavir marboxil were collected from the FDA adverse event reporting system (FAERS) between the first quarter in 2004 and the third quarter in 2022, and mined by using reporting odds ratio (ROR) method. The designated medical events (DME) were estimated. The system organ class (SOC) in the Medical Dictionary for Regulatory Activities (MedDRA, version 25.0) was used for the classification and statistics of drug ADE terminology. RESULTS A total of 12 636, 1 749 and 1 283 ADE reports were retrieved for oseltamivir, zanamivir and baloxavir marboxil, involving 26, 16 and 17 SOCs, respectively. Oseltamivir was strongly associated with sleep terror, abnormal behavior, hallucination and delirium. Zanamivir was implicated in abnormal behavior, delirium, incoherence, and altered state of consciousness with prominent signal intensity. Baloxavir marboxil was strongly associated with ischemic colitis, hemorrhagic cystitis, erythema multiforme and melaena. Erythema multiform was detected in the DME of three drugs with strong signals. CONCLUSIONS When clinically administering the three drugs, it is crucial to pay close attention to both common adverse reactions and those ADEs that are not explicitly mentioned in the drug instructions. For oseltamivir, clinicians should exercise caution due to the potential risk of acute kidney injury and fulminant hepatitis, necessitating regular monitoring of the patient’s liver and kidney function. When prescribing zanamivir, caution should be exercised due to ADEs related to the respiratory system, including acute respiratory distress syndrome and respiratory failure, necessitating close monitoring of the patient’s respiratory status. Similarly, for baloxavir marboxil, clinicians should be vigilant for potential ADEs such as erythema multiforme and rhabdomyolysis.

RESUMO

OBJECTIVE To provide a reference for safe drug use in clinic. METHODS ADE reports related to nilotinib from the first quarter of 2007 to the fourth quarter of 2022 were collected from the US FDA adverse event reporting system database. The reporting odds ratio (ROR) and proportional reporting ratio (PRR) of disproportionality measures were used to mine potential ADE signals,which were compared with drug instruction and related case report, and were screened and analyzed according to the designated medical events (DME) list formulated by the European Medicines Agency. RESULTS Totally 23 332 cases of ADE with nilotinib as the primary suspected drug were reported. A total of 359 positive signals were obtained,involving 24 system organ classes (SOC),mainly concentrated in various examinations,heart organ diseases,vascular and lymphatic diseases,all kinds of nervous system diseases,etc. Among them,ADEs such as vertebral artery stenosis,coronary artery stenosis,arterial disease,liver infection and the second primary malignant tumor were not mentioned in the instructions. Seven DMEs were detected,of which bone marrow failure,pulmonary hypertension and deafness were not mentioned in the drug instruction. CONCLUSIONS The common ADE signals of nilotinib excavated in this study are consistent with the instructions. In clinical use,special attention should be paid to DME not mentioned in the instructions such as bone marrow failure,pulmonary hypertension and deafness; cardiac function, blood glucose and blood lipid indexes should be monitored closely.

RESUMO

OBJECTIVE@#To identify and characterize read-through RNAs and read-through circular RNAs (rt-circ-HS) derived from transcriptional read-through hypoxia inducible factor 1α (HIF1α) and small nuclear RNA activating complex polypeptide 1 (SNAPC1) the two adjacent genes located on chromosome 14q23, in renal carcinoma cells and renal carcinoma tissues, and to study the effects of rt-circ-HS on biological behavior of renal carcinoma cells and on regulation of HIF1α.@*METHODS@#Reverse transcription-polymerase chain reaction (RT-PCR) and Sanger sequencing were used to examine expression of read-through RNAs HIF1α-SNAPC1 and rt-circ-HS in different tumor cells. Tissue microarrays of 437 different types of renal cell carcinoma (RCC) were constructed, and chromogenic in situ hybridization (ISH) was used to investigate expression of rt-circ-HS in different RCC types. Small interference RNA (siRNA) and artificial overexpression plasmids were designed to examine the effects of rt-circ-HS on 786-O and A498 renal carcinoma cell proliferation, migration and invasiveness by cell counting kit 8 (CCK8), EdU incorporation and Transwell cell migration and invasion assays. RT-PCR and Western blot were used to exa-mine expression of HIF1α and SNAPC1 RNA and proteins after interference of rt-circ-HS with siRNA, respectively. The binding of rt-circ-HS with microRNA 539 (miR-539), and miR-539 with HIF1α 3' untranslated region (3' UTR), and the effects of these interactions were investigated by dual luciferase reporter gene assays.@*RESULTS@#We discovered a novel 1 144 nt rt-circ-HS, which was derived from read-through RNA HIF1α-SNAPC1 and consisted of HIF1α exon 2-6 and SNAPC1 exon 2-4. Expression of rt-circ-HS was significantly upregulated in 786-O renal carcinoma cells. ISH showed that the overall positive expression rate of rt-circ-HS in RCC tissue samples was 67.5% (295/437), and the expression was different in different types of RCCs. Mechanistically, rt-circ-HS promoted renal carcinoma cell proliferation, migration and invasiveness by functioning as a competitive endogenous inhibitor of miR-539, which we found to be a potent post-transcriptional suppressor of HIF1α, thus promoting expression of HIF1α.@*CONCLUSION@#The novel rt-circ-HS is highly expressed in different types of RCCs and acts as a competitive endogenous inhibitor of miR-539 to promote expression of its parental gene HIF1α and thus the proliferation, migration and invasion of renal cancer cells.

RESUMO

This paper aimed to study the effect of Dalbergia cochinchinensis heartwood on plasma endogenous metabolites in rats with ligation of the left anterior descending coronary artery, and to analyze the mechanism of D. cochinchinensis heartwood in improving acute myocardial ischemic injury. The stability and consistency of the components in the D. cochinchinensis heartwood were verified by the establishment of fingerprint, and 30 male SD rats were randomly divided into a sham group, a model group, and a D. cochinchinensis heartwood(6 g·kg~(-1)) group, with 10 rats in each group. The sham group only opened the chest without ligation, while the other groups established the model of ligation. Ten days after administration, the hearts were taken for hematoxylin-eosin(HE) staining, and the content of heart injury indexes in the plasma creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH), energy metabolism-related index glucose(Glu) content, and vascular endothelial function index nitric oxide(NO) was determined. The endogenous metabolites were detected by ultra-high-performance liquid chromatography-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS). The results showed that the D. cochinchinensis heartwood reduced the content of CK-MB and LDH in the plasma of rats to relieve myocardial injury, reduced the content of Glu in the plasma, improved myocardial energy metabolism, increased the content of NO, cured the vascular endothelial injury, and promoted vasodilation. D. cochinchinensis heartwood improved the increase of intercellular space, myocardial inflammatory cell infiltration, and myofilament rupture caused by ligation of the left anterior descending coronary artery. The metabolomic study showed that the content of 26 metabolites in the plasma of rats in the model group increased significantly, while the content of 27 metabolites decreased significantly. Twenty metabolites were significantly adjusted after the administration of D. cochinchinensis heartwood. D. cochinchinensis heartwood can significantly adjust the metabolic abnormality in rats with ligation of the left anterior descending coronary artery, and its mechanism may be related to the regulation of cardiac energy metabolism, NO production, and inflammation. The results provide a corresponding basis for further explaining the effect of D. cochinchinensis on the acute myocardial injury.

RESUMO

We provide two datasets for tracking the debris flow induced by the 2008 Wenchuan Mw 7.9 earthquake on a section of the Longmen mountains on the eastern side of the Tibetan plateau (Sichuan, China). The database was obtained through a literature review and field survey reports in the epicenter area, combined with high-resolution remote sensing image and extensive data collection and processing. The first dataset covers an area of 892 km2, including debris flows from 2008 to 2020 (an updated version). 186 debris flows affecting 79 watersheds were identified. 89 rainfall stations were collected to determine the rainfall events for the post-earthquake debris flow outbreak. The second database is a list of mitigation measures for post-earthquake debris flows, including catchment name, check dam number, coordinates, construction time, and successful mitigation date. The datasets can aid different applications, including the early warning and engineering prevention of post-earthquake debris flow, as well as provide valuable data support for research in related disciplines.

RESUMO

Obtaining high-quality embryos is one of the key factors to improve the clinical pregnancy rate of assisted reproductive technologies (ART). So far, the clinical evaluation of embryo quality depends on embryo morphology. However, the clinical pregnancy rate is still low. Therefore, new indicators are needed to further improve the evaluation of embryo quality. Several studies have shown that the decrease of sperm-specific protein actin-like 7A (ACTL7A) leaded to low fertilization rate, poor embryo development, and even infertility. The aim of this study was to study whether the different expression levels of ACTL7A on sperm can be used as a biomarker for predicting embryo quality. In this study, excluding the factors of severe female infertility, a total of 281 sperm samples were collected to compare the ACTL7A expression levels of sperms with high and low effective embryo rates and analyze the correlation between protein levels and in-vitro fertilization (IVF) laboratory outcomes. Our results indicated that the ACTL7A levels were significantly reduced in sperm samples presenting poor embryo quality. Furthermore, the protein levels showed a significant correlation with fertilization outcomes of ART. ACTL7A has the potential to be a biomarker for predicting success rate of fertilization and effective embryo and the possibility of embryo arrest. In conclusion, sperm-specific protein ACTL7A has a strong correlation with IVF laboratory outcomes and plays important roles in fertilization and embryo development.

RESUMO

Corticosteroid switching can reverse abiraterone resistance in some patients with metastatic castration-resistant prostate cancer (mCRPC). Here, we investigated the potential biomarkers for predicting the efficacy of corticosteroid switching during treatment with abiraterone acetate (AA). We retrospectively analyzed 101 mCRPC patients receiving corticosteroid switching from West China Hospital and Sun Yat-Sen University Cancer Center between January 2016 and December 2018. All cases received AA plus prednisone as first-line therapy during mCRPC. Primary end points were biochemical progression-free survival (bPFS) and overall survival (OS). The risk groups were defined based on multivariate analysis. A total of 42 (41.6%) and 25 (24.8%) patients achieved 30% and 50% decline in prostate-specific antigen (PSA), respectively, after corticosteroid switching. The median bPFS and median OS on AA plus dexamethasone were 4.9 (95% confidence interval [CI]: 3.7-6.0) months and 18.8 (95% CI: 16.2-30.2) months, respectively. Aldo-keto reductase family 1 member C3 (AKR1C3) expression (hazard ratio [HR]: 2.15, 95% Cl: 1.22-3.80, P = 0.008) and baseline serum alkaline phosphatase (ALP; HR: 4.95, 95% Cl: 2.40-10.19, P < 0.001) were independent predictors of efficacy before corticosteroid switching in the multivariate analysis of bPFS. Only baseline serum ALP >160 IU l-1 (HR: 3.41, 95% Cl: 1.57-7.38, P = 0.002) together with PSA level at switch ≥50 ng ml-1 (HR: 2.59, 95% Cl: 1.22-5.47, P = 0.013) independently predicted poorer OS. Based on the predictive factors in multivariate analysis, we developed two risk stratification tools to select candidates for corticosteroid switching. Detection of serum ALP level, PSA level, and tissue AKR1C3 expression in mCRPC patients could help make clinical decisions for corticosteroid switching.

RESUMO

Objective: To analyze the correlation between loss of smell/taste and the number of real confirmed cases of coronavirus disease 2019 (COVID-19) worldwide based on Google Trends data, and to explore the guiding role of smell/taste loss for the COVID-19 prevention and control. Methods: "Loss of smell" and "loss of taste" related keywords were searched in the Google Trends platform, the data were obtained from Jan. 1 2019 to Jul. 11 2021. The daily and newly confirmed COVID-19 case number were collected from World Health Organization (WHO) since Dec. 30 2019. All data were statistically analyzed by SPSS 23.0 software. The correlation was finally tested by Spearman correlation analysis. Results: A total of data from 80 weeks were collected. The retrospective analysis was performed on the new trend of COVID-19 confirmed cases in a total of 186 292 441 cases worldwide. Since the epidemic of COVID-19 was recorded on the WHO website, the relative searches related to loss of smell/taste in the Google Trends platform had been increasing globally. The global relative search volumes of "loss of smell" and "loss of taste" on Google Trends was 10.23±2.58 and 16.33±2.47 before the record of epidemic while 80.25±39.81 and 80.45±40.04 after (t value was 8.67, 14.43, respectively, both P<0.001). In the United States and India, the relative searches for "loss of smell" and "loss of taste" after the record of epidemic were also much higher than before (all P<0.001). The correlation coefficients between the trend of weekly new COVID-19 cases and the Google Trends of "loss of smell" in the global, United States, and India was 0.53, 0.76, and 0.82 respectively (all P<0.001), the correlation coefficients with Google Trends of "loss of taste" was 0.54, 0.78, and 0.82 respectively (all P<0.001). The lowest and highest point of loss of smell/taste search curves of Google Trends in different periods appeared 7 to 14 days earlier than that of the weekly newly COVID-19 confirmed cases curves, respectively. Conclusions: There is a significant positive correlation between the number of newly confirmed cases of COVID-19 worldwide and the amount of keywords, such as "loss of smell" and "loss of taste", retrieved in Google Trends. The trend of big data based on Google Trends might predict the outbreak trend of COVID-19 in advance.

RESUMO

Objective:To investigate the effect of attention and interpretation therapy on posttraumatic stress disorder and perceived stress of parents with children having developmental dislocation of the hip.Methods:Totally 96 parents with children having developmental dislocation of the hip from women and children hospital of Hubei province were divided into experimental group ( n=46) and control group ( n=46) according to the random number table method. The control group received routine postoperative DDH care. On the basis of this, the experimental group was given attention and interpretation therapy for 8 weeks. Before intervention and at the end of intervention, the effects were assessed by Posttraumatic Stress Checklist-Civilian Version (PCL-C) and Chinese Perceived Stress Scale (CPSS). Results:After intervention, the scores of arousal symptoms, avoidance/numbing, re-experiencing symptoms and total PCL-C scores were 8.47±2.30, 10.67±2.67, 7.49±2.63, 26.62±4.10, in addition, the scores of sense of tension, sense of out of control and total scores of CPSS were 11.71±2.21, 11.27±2.95, 22.98±3.77, which were significantly lower than those in the control group (9.45±2.33, 12.39±2.43, 8.93±2.79, 30.77±5.30, 12.86±3.05, 13.09±3.46, 25.95±4.52), the difference was statistically significant ( t value was 2.013-4.135, P<0.05). Conclusion:Attention and interpretation therapy can effectively relieve posttraumatic stress disorder symptom and alleviate perceived stress level of parents with children having developmental dislocation of the hip.

RESUMO

OBJECTIVE: To mine and evaluate the post-marketing safety alert signals of pegaspargase (PEG-ASP) and L-asparaginase (L-ASP),and compare the safety differences between them ,so as to provide reference for clinical safe and rational drug use. METHODS : The adverse drug event (ADE) reports of PEG-ASP and L-ASP issued by FDA adverse event reporting system from Jan. 1st,2004-Jun. 30th,2020 were retrieved. BCPNN method was used to mine the safety signals of these two drugs under the condition that the lower limit of information component (IC-2SD)>0 and the number of events ≥3. The medium and strong signals of two drugs with IC -2SD≥1.5 were evaluated and compared in 8 system organ class,such as gastrointestinal system ,hepatobiliary system ,blood and lymphatic system ,blood vessels and lymphatic vessels , nervous system ,immune system ,metabolism and nutrition ,various examinations. IC value of specific ADE signal and its 95% confidence interval were analyzed by time scanning spectrum. RESULTS & CONCLUSIONS :The reports of PEG-ASP and L-ASP as suspected drugs were 2 324 and 3 824;67 and 68 medium and strong signals were included ,respectively. In gastrointestinal system,the common strong signal of PEG-ASP and L-ASP was necrotic pancreatitis. In hepatobiliary system ,both of them showed strong signal in venoocclusive liver disease ,and this ADE was not included in the drug instruction. In blood and lymphatic system , common strong signals of the two drugs were febrile neutropenia ,coagulation disorder ,neutropenia and febrile bone marrow regeneration disorder ;in blood vessels and lymphatic vessels ,in addition to haemodynamic instability ,IC values of other signals of L-ASP were higher than those of PEG-ASP. In nervous system ,IC values of other signals of L-ASP were higher than those of PEG-ASP except for intracranial haemorrhage. In immune system ,anaphylactic reaction was a medium signal for L-ASP but was a strong signal for PEG-ASP. In metabolism and nutritional diseases ,except for tumor lysis syndrome ,IC values of other signals of L-ASP were higher than those of PEG-ASP. The results of time scanning spectrum showed that the signals of necrotic pancreatitis and coagulation disorder of PEG-ASP were stable ,while the signals of veno occlusive liver disease and hypersensitivity were unstable and needed to be observed ;above four signals of L-ASP were stable signals. When using PEG-ASP or L-ASP clinically , close attention should be paid to the safety problems such as hypersensitivity ,coagulation disorder ,thrombosis,necrotic pancreatitis,venoocclusive liver disease and hypoproteinemia.

RESUMO

@#Objective    To investigate the effectiveness of sublobar resection and lobectomy via uniportal video-assisted thoracoscopic surgery (U-VATS) for lung metastases from colorectal cancer. Methods    Retrospective research was conducted on 42 colorectal cancer patients with lung metastases who underwent U-VATS sublobar resection and lobectomy at the Tongji Hospital, Huazhong University of Science and Technology between April 2016 and May 2019, including 24 males and 18 females with an average age of 58.0±9.9 years. Among them 17 patients received U-VATS sublobar resection and 25 patients received lobectomy. The operation time, intraoperative blood loss, postoperative pulmonary infection, drainage tube indwelling time, drainage volume on the first day after surgery, postoperative hospital stay were analyzed between the two groups, and the relationship between the prognosis and clinical characteristics of the two groups was compared. Results    Sublobar resection patients had less lung metastases (P=0.043) and shorter operation time (P=0.023) compared with the lobectomy patients. There was no significant difference between the lobectomy and sublobar resection groups in intraoperative blood loss (P=0.169), rate of postoperative infection (P=0.982), postoperative drainage duration (P=0.265), drainage volume on the first day after surgery (P=0.402) and postoperative hospital stay (P=0.612). The progression-free survival of the two groups was 25.19 months and 23.63 months (P=0.721), and their overall survival was 29.09 months and 30.64 months (P=0.554). Conclusion    Considering guantity and locations of lung metastases, U-VATS sublobar resection can achieve a similar prognosis to lobectomy for lung metastases from colorectal cancer. Further efficacy of this surgical strategy remains to be proved by longer follow-up.

RESUMO

Objective@#To investigate the multidetector computed tomography (MDCT) features of fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) with germline or somatic mutations, and compare them with those of papillary type II RCC (pRCC type II). @*Materials and Methods@#A total of 24 patients (mean ± standard deviation, 40.4 ± 14.7 years) with pathologically confirmed FH-deficient RCC (15 with germline and 9 with somatic mutations) and 54 patients (58.6 ± 12.6 years) with pRCC type II were enrolled. The MDCT features were retrospectively reviewed and compared between the two entities and mutation subgroups, and were correlated with the clinicopathological findings. @*Results@#All the lesions were unilateral and single. Compared with pRCC type II, FH-deficient RCC was more prevalent among younger patients (40.4 ± 14.7 vs. 58.6 ± 12.6, p < 0.001) and tended to be larger (8.1 ± 4.1 vs. 5.4 ± 3.2, p = 0.002). Cystic solid patterns were more common in FH-deficient RCC (20/24 vs. 16/54, p < 0.001), with 16 of the 20 (80.0%) cystic solid tumors having showed typical polycystic and thin smooth walls and/or septa, with an eccentric solid component. Lymph node (16/24 vs. 16/54, p = 0.003) and distant (11/24 vs. 3/54, p < 0.001) metastases were more frequent in FH-deficient RCC. FHdeficient RCC and pRCC type II showed similar attenuation in the unenhanced phase. The attenuation in the corticomedullary phase (CMP) (76.3% ± 25.0% vs. 60.2 ± 23.6, p = 0.008) and nephrographic phase (NP) (87.7 ± 20.5, vs. 71.2 ± 23.9, p = 0.004), absolute enhancement in CMP (39.0 ± 24.8 vs. 27.1 ± 22.7, p = 0.001) and NP (50.5 ± 20.5 vs. 38.2 ± 21.9, p = 0.001), and relative enhancement ratio to the renal cortex in CMP (0.35 ± 0.26 vs. 0.24 ± 0.19, p = 0.001) and NP (0.43 ± 0.24 vs. 0.29 ± 0.19, p < 0.001) were significantly higher in FH-deficient RCC. No significant difference was found between the FH germline and somatic mutation subgroups in any of the parameters. @*Conclusion@#The MDCT features of FH-deficient RCC were different from those of pRCC type II, whereas there was no statistical difference between the germline and somatic mutation subgroups. A kidney mass with a cystic solid pattern and metastatic tendency, especially in young patients, should be considered for FH-deficient RCC.

RESUMO

【Objective】 To analyze the frequency and profile of irregular antibodies in different ethnic groups through screening and identification of irregular antibodies in 67 552 blood recipients in the Affiliated Hospital of Guizhou Medical University. 【Methods】 Irregular antibody screening was carried out in patients with different ethnic groups from August 1, 2016 to July 31, 2019 by microcolumn gel anti human globulin method, and the irregular antibody specificity were identified by panel cells. 【Results】 1)307 out of 67 552 cases were positive for irregular antibody, with the positive rate at 0.45%(307/67 552). Among them, Chuanqing was 1.27%(6/473), Yi 1.15%(4/348), Buyi 1.03%(10/975), Dong 0.58%(3/514), Han 0.44%(273/62 365), Miao 0.42%(5/1 187) and Tujia 0.34%(2/596), with significant differences among nationalities. Irregular antibody detection: the positive rate of female patients(0.56%, 223/41 359) was higher than that of male patients(0.32%, 84/26 193)(P0.05). The yields of irregular antibodies did not differ by ABO blood groups(P>0.05). 3)The specificity of 307 irregular antibody positive cases involved 7 blood group systems, including Rh system 59.28%(182/307), MNSs system 9.12%(28/307), Kidd system 0.65%(2/307), Duffy system 0.98%(3/307), Lewis system 5.86%(18/307), P system 0.65%(2/307), and Digeo system 0.33%(1/307). In addition, 15.64%(48/307) of autoantibodies, 0.65%(2/307) of cold antibodies and 4.93%(15/307) of unclear antibodies were detected. 4)The distribution of anti-D, anti-C and autoantibodies were statistically significant among the Han, Buyi, Chuanqing, Miao, Yi and Dong nationalities(P0.05). 【Conclusion】 The distribution of irregular antibodies in Guizhou is different by nationalities. Routine screening of irregular antibodies for transfused or pregnant patients can increase the safety and efficacy of blood transfusion. Most of the irregular antibodies detected are Rh blood group system. The exposure to irregular antibodies can be reduced by additional detection of blood group antigen other than RhD for blood recipients and donors, as well as the blood transfusion with matched blood group antigens.

RESUMO

OBJECTIVE@#To investigate the incidence and clinicopathologic features of cervical lymph node metastasis in salivary gland adenoid cystic carcinoma (AdCC).@*METHODS@#Retrospective analysis was made in 798 AdCC patients who underwent tumor resection during January, 2001 to January, 2019 in Peking University School and Hospital of Stomatology, especially the clincopathologic characteristics of 82 cases with lymph node metastasis.@*RESULTS@#In the study, 82 of the 798 patients were identified with cervical lymph node metastasis, which was confirmed by histopathological examination. The palate, the region of sublingual gland and mouth floor, and the parotid were the frequently involved primary sites for AdCCs. The general incidence rate of lymph node metastasis was approximately 10%. The submandibular gland, the region of sublingual gland and mouth floor, and the mobile tongue were the most frequent sites of lymph node metastasis with the incidence rates of 20.8%, 16.1%, and 15.1%, respectively; while lymph node metastasis was uncommon in the tumors which were the origin from the palate and parotid, with incidence rates of 6.1% and 3.4%, respectively. Most AdCC cases (70.7%) showed the classic "tunnel-style" metastatic pattern of occurrence, and the level I and II regions were the most frequently involved areas. The 5-year and 10-year overall survival rates of the patients with lymph node metastasis were 77.4% and 20.6% respectively, while the 5-year and 10-year overall survival rates of the patients with no lymph node metastasis were 83.5% and 57.6%, respectively. The univariate analysis demonstrated that statistically significant differences in the overall survival for the presence of lymph node metastasis (P<0.001). In the meantime, the 5-year disease-free survival rate of the patients with lymph node metastasis also showed statistically significant differences to that of the AdCC patients with no lymph node metastasis. In addition, the primary site and histological grade were significantly associated with lymph node metastasis, and the high-grade solid growth pattern was identified as a strong predictor for the occurrence of lymph node metastasis.@*CONCLUSION@#Cervical lymph node metastasis has a high tendency of occurrence in submandibular gland and tongue-mouth floor complex, and the high-grade solid growth pattern could be taken as a strong predictor for the occurrence of lymph node metastasis, which correlates to poor prognosis of AdCC patients. A selective neck dissection should be considered as a management in such patients.
