Impact of uterine artery embolization on ovarian function and pregnancy outcome after uterine-fibroids treatment:A prospective study

Uterine fibroids are benign tumors that originate from smooth muscle cells of the uterus.It is the most common gynecological disorder,affecting up to 80%of women of reproductive age.Uterine fibroids can cause various symptoms such as abnormal uterine bleeding,pelvic pain,infertility,and pregnancy complications.The treatment options for uterine fibroids include medical therapy,surgical intervention,and minimally invasive techniques.AIM To compare ovarian function of women with uterine fibroids who did or did not undergo uterine artery embolization(UAE).METHODS This prospective cohort study enrolled 87 women with symptomatic uterine fibroids who underwent UAE,and 87 women with the same symptoms who did not undergo UAE but received conservative management or other treatments.The two groups were matched for age,body mass index,parity,and baseline characteristics of uterine fibroids.The primary outcome was ovarian function that was evaluated by serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),and anti-Müllerian hormone(AMH),as well as ovarian reserve tests,such as antral follicle count(AFC)and ovarian volume(OV).The secondary outcome was fertility that was evaluated based on the menstrual cycle,ovulation,conception,pregnancy,and delivery.The participants were followed-up for 36 months and assessed at 1,3,6,12,24,and 36 months after treatment.RESULTS The study found that the most common minor complication of UAE was postembolization syndrome in 73.6% of women,resolving within a week.No significant differences were observed between the UAE group and the control group in serum levels of reproductive hormones(FSH,LH,E2,AMH)and ovarian reserve indicators(AFC,OV)at any point up to 36 months post-treatment.Additionally,there were no significant differences in conception,pregnancy,or delivery rates,with the average time to conception and gestational age at delivery being similar between the two groups.Birth weights were also comparable.Finally,there was no significant correlation between ovarian function,fertility indicators,and the type or amount of embolic agent used or the change in fibroids posttreatment.CONCLUSION UAE resulted in significantly positive pregnancy outcomes,no adverse events post-treatment,and is a safe and effective treatment for uterine fibroids that preserves ovarian function and fertility.

Portal vein computed tomography imaging characteristics and their relationship with bleeding risk in patients with liver cirrhosis undergoing interventional therapy

BACKGROUND This study aimed to analyze the predictive value of multi-slice spiral computed tomography(CT)perfusion imaging for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension.A total of 62 patients with cirrhotic portal hypertension and 28 healthy individuals were included.The results showed that multi-slice spiral CT perfusion imaging had a significant predictive value for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension.The vascular area,number of vascular cross-sections,and gastric coronary vein diameter(GCVD)showed high predictive values,with the vascular area having the best predictive value.AIM To investigate the predictive accuracy of multi-slice spiral CT perfusion imaging for upper gastrointestinal bleeding in patients with cirrhosis and portal hypertension.METHODS This study included 62 patients with cirrhotic portal hypertension(disease group)and 28 healthy individuals(control group).The disease group was further divided into two subgroups:Group A(n=27,bleeding)and group B(n=35,no bleeding).All patients underwent multi-slice spiral CT perfusion imaging at our hospital,and we compared various parameters such as liver blood flow,vein size,number of blood vessels,and blood vessel area between the two groups.We employed statistical analysis to identify factors associated with upper gastrointestinal bleeding and created a graph comparing the predictive value of different factors for bleeding.RESULTS We found no difference in hepatic artery(HAP)levels among the three groups(all P>0.05).The portal vein levels in groups A and B were much lower than in the control group;group A was much lower than group B(all P<0.05).The HAP perfusion index levels in groups A and B were much higher than in the control group;group A was much higher than group B(all P<0.05).The portal vein diameter,splenic vein diameter,and GCVD levels in groups A and B were much higher than in the control group;those in group A were much higher than those in group B(all P<0.05).The number of blood vessels and blood vessel area in groups A and B were much higher than in the control group;those in group A were much higher than those in group B(all P<0.05).The statistical method showed a strong link between GCVD,number of blood vessels,blood vessel area,and upper gastrointestinal bleeding(odds ratio=1.275,1.346,1.397,P<0.05).The graph showed that GCVD,number of blood vessels,and blood vessel area could predict bleeding well,with blood vessel area having the best prediction power.CONCLUSION That multi-slice spiral CT perfusion imaging can predict upper gastrointestinal bleeding well in patients with cirrhosis and high blood pressure in the portal vein.GCVD,number of blood vessels,and blood vessel area had high prediction power.The blood vessel area had the best prediction power,with an area under the curve of 0.831.

Metabolic alteration of neuroactive steroids and protective effect of progesterone in Alzheimer's disease-like rats

A correlation between metabolic alterations of neuroactive steroids and Alzheimer’s disease remains unknown. In the present study, amyloid beta （Aβ） 25-35 （Aβ25-35） injected into the bilateral campus CA1 region significantly reduced learning and memory. At the biochemical level, hippocampal levels of pregnenolone were significantly reduced with Aβ25-35 treatment. Furthermore, progesterone was considerably decreased in the prefrontal cortex and hippocampus, and 17β-estradiol was signifi-cantly elevated. To our knowledge, this is the first report showing that Aβ25-35, a main etiological factor of Alzheimer’s disease, can alter the level and metabolism of neuroactive steroids in the prefrontal cortex and hippocampus, which are brain regions significantly involved in learning and memory. Aβ25-35 exposure also increased the expression of inflammatory mediators, tumor necrosis factor-αand interleukin-1β. However, subcutaneous injection of progesterone reversed the upregulation of tumor necrosis factor-αand interleukin-1βin a dose-dependent manner. Concomitant with improved cognitive abilities, progesterone blocked Aβ-mediated inflammation and increased the survival rate of hippocampal pyramidal cells. We thus hypothesize that Aβ-mediated cognitive deficits may occur via changes in neuroactive steroids. Moreover, our findings provide a possible therapeutic strategy for Alzheimer’s disease via neuroactive steroids, particularly progesterone.

The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women

Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus （GDM）. Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks＇ gestation （WG）. Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDIVl morbidity. Results Age, pre-pregnant body weight （BW）, and body mass index （BMI） were associated with increased risk of GDM. Fat mass （FM）, fat mass percentage （FMP）, extracellular water （ECW）, BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass （FFM）, muscular mass （MM）, and intracellular water （ICW） were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.

Ultrasound measurement of the corpus callosum and neural development of premature infants

Length and thickness of 152 corpus callosa Using ultrasonic diagnostic equipment with a were measured in neonates within 24 hours ot b^rtn. neonatal brain-specific probe, corpus callosum length and thickness of the genu, body, and splenium were measured on the standard mid-sagittal plane, and the anteroposterior diameter of the genu was measured in the coronal plane. Results showed that corpus callosum length as well as thickness of the genu and splenium increased with gesta- tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus callosum de- velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus callosum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose ges- tational age was 34 weeks or less. Corpus callosum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus callosum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus callosum growth in premature infants is associated with neurobehavioral development during the early extrauterine stage.

Kappa angles in different positions in patients with myopia during LASIK

AIM： To investigate the difference in kappa angle between sitting and supine positions during laser-assisted in situ keratomileusis（LASIK）.·METHODS： A retrospective study was performed on395 eyes from 215 patients with myopia that received LASIK. Low, moderate, and high myopia groups were assigned according to diopters. The horizontal and vertical components of kappa angle in sitting position were measured before the operation, and in supine position during the operation. The data from the two positions were compared and the relationship between kappa angle and diopters were analyzed.· RESULTS： Two hundred and twenty-three eyes（56.5%） in sitting position and 343 eyes（86.8%） in supine position had positive kappa angles. There were no significant differences in horizontal and vertical components of kappa angle in the sitting position or horizontal components of kappa angle in the supine position between the three groups（P 〉0.05）. A significant difference in the vertical components of kappa angle in the supine position was seen in the three groups（P 〈0.01）. Differences in both horizontal and vertical components of kappa angles were significant between the sitting and supine positions. Positive correlations in both horizontal and vertical components of kappa angles（P 〈0.05） were found and vertical components of kappa angle in sitting and supine positions were negatively correlated with the degree of myopia（sitting position： r =-0.109; supine position： r =-0.172; P 〈0.05）.·CONCLUSION： There is a correlation in horizontal and vertical components of kappa angle in sitting and supine positions. Positive correlations in both horizontal and vertical components of kappa angle in sitting and supine positions till the end of the results. This result still needs further observation. Clinicians should take into account different postures when excimer laser surgery needs to be performed.

Whole transcriptome analysis on blue light-induced eye damage

AIM:To analyze abnormal gene expressions of mice eyes exposed to blue light using RNA-seq and analyze the related signaling pathways.METHODS:Kunming mice were divided into an experimental group that was exposed to blue light and a control group that was exposed to natural light.After 14 d,the mice were euthanized and their eyeballs were collected.Whole transcriptome analysis was attempted to analyze the gene expression of the eyeballs using RNA-seq to reconstruct genetic networks.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis were used to reveal the related signaling pathways.RESULTS:The 737 differentially expressed genes were identified,including 430 up and 307 down regulated genes,by calculating the gene FPKM in each sample and conducting differential gene analysis.GO and KEGG pathway enrichment analysis showed that blue light damage may associated with the visual perception,sensory perception of light stimulus,phototransduction,and JAKSTAT signaling pathways.Differential lnc RNA,circ RNA and mi RNA analysis showed that blue light exposure affected pathways for retinal cone cell development and phototransduction,among others.CONCLUSION:Exposure to blue light can cause a certain degree of abnormal gene expression and modulate signaling pathways in the eye.

Evaluation of non-verbal cognitive function in infants with severe hearing impairment

BACKGROUND： The relationship between hearing impairment and verbal developmental deficits in infants has become a hotspot in research, focusing on improving hearing and promoting verbal development. However, language is only one element of cognition. There are other elements of non-verbal cognitive deficits in infants with hearing impairment. OBJECTIVE： This study was designed to compare the differences in gross motor, fine motor, adaptability, and behavioral development between infants with severe hearing impairment and ordinary children of the same age. DESIGN： Case-control observation. SETTING： Department of Otolaryngology-Head Surgery, Bethune International Peace Hospital. PARTICIPANTS： Fifty-two infants with hearing impairment, who received treatment in the Department of Otolaryngology-Head Surgery, Bethune International Peace Hospital from February to December 2007, were confirmed to suffer from severe （or extremely severe） sensorineural deafness by auditory brain-stem response （ABR） and were recruited for this study. The infants comprised 30 males and 22 females. Among them, 18 were aged 0-1 year, 18 were aged 1-2 years, and 16 were aged 2-3 years. An additional 60 individuals, aged 0-3 years, who received developmental monitoring simultaneously, and were confirmed to have normal hearing and verbal ability, were included as controls. Among the control subjects, there were 31 males and 29 females： 20 were 〈 1 year of age, 22 were between 1-2 years of age, and 18 were between 2-3 years of age. Informed consent for laboratory measurements was obtained from each infant＇s guardian, and the study was approved by the Hospital Ethics Committee. METHODS： Infant gross motor, fine motor, adaptability, and behavioral development were assessed in the hearing impairment and control infants. Comparison results were expressed as grading standards of development quotient. MAIN OUTCOME MEASURES： Developmental quotient of all subjects was determined using ＂psychometric test battery for 0-6 year-old infants＂, revised by Capital Institute of Pediatrics. Developmental quotient of each factor ≥ 130 points and 〈 69 points was defined as excellent and mentally disabled, respectively. RESULTS： All determination results were included in the final analysis. There was no significant difference in each factor between hearing-impaired and control infants, who were 1-year-old （P 〉 0.05）. The behavioral developmental quotient was significantly less in hearing-impaired infants compared to control infants, who were between 1 and 2 years of age （P 〈 0.05）. The development quotients of fine motor and behavioral development were significantly less in hearing-impaired infants than in control infants, who were 2 3 years of age （P 〈 0.05）. CONCLUSION： Compared to control infants, severe hearing-impaired infants have a lower behavioral developmental quotient after 1 year and a lower fine motor developmental quotient after 2 years of age.

Clinical practice guideline for transurethral plasmakinetic resection of prostate for benign prostatic hyperplasia(2021 Edition)

Benign prostatic hyperplasia (BPH) is highly prevalent among older men, impacting on their quality of life, sexual function, and genitourinary health, and has become an important global burden of disease. Transurethral plasmakinetic resection of prostate (TUPKP) is one of the foremost surgical procedures for the treatment of BPH. It has become well established in clinical practice with good efficacy and safety. In 2018, we issued the guideline “2018 Standard Edition”. However much new direct evidence has now emerged and this may change some of previous recommendations. The time is ripe to develop new evidence-based guidelines, so we formed a working group of clinical experts and methodologists. The steering group members posed 31 questions relevant to the management of TUPKP for BPH covering the following areas: questions relevant to the perioperative period (preoperative, intraoperative, and postoperative) of TUPKP in the treatment of BPH, postoperative complications and the level of surgeons’ surgical skill. We searched the literature for direct evidence on the management of TUPKP for BPH, and assessed its certainty generated recommendations using the grade criteria by the European Association of Urology. Recommendations were either strong or weak, or in the form of an ungraded consensus-based statement. Finally, we issued 36 statements. Among them, 23 carried strong recommendations, and 13 carried weak recommendations for the stated procedure. They covered questions relevant to the aforementioned three areas. The preoperative period for TUPKP in the treatment of BPH included indications and contraindications for TUPKP, precautions for preoperative preparation in patients with renal impairment and urinary tract infection due to urinary retention, and preoperative prophylactic use of antibiotics. Questions relevant to the intraoperative period incorporated surgical operation techniques and prevention and management of bladder explosion. The application to different populations incorporating the efficacy and safety of TUPKP in the treatment of normal volume (< 80 ml) and large-volume (≥ 80 ml) BPH compared with transurethral urethral resection prostate, transurethral plasmakinetic enucleation of prostate and open prostatectomy;the efficacy and safety of TUPKP in high-risk populations and among people taking anticoagulant (antithrombotic) drugs. Questions relevant to the postoperative period incorporated the time and speed of flushing, the time indwelling catheters are needed, principles of postoperative therapeutic use of antibiotics, follow-up time and follow-up content. Questions related to complications incorporated types of complications and their incidence, postoperative leukocyturia, the treatment measures for the perforation and extravasation of the capsule, transurethral resection syndrome, postoperative bleeding, urinary catheter blockage, bladder spasm, overactive bladder, urinary incontinence, urethral stricture, rectal injury during surgery, postoperative erectile dysfunction and retrograde ejaculation. Final questions were related to surgeons’ skills when performing TUPKP for the treatment of BPH. We hope these recommendations can help support healthcare workers caring for patients having TUPKP for the treatment of BPH.

Decreased AKAP4/PKA signaling pathway in high DFI sperm affects sperm capacitation

The sperm DNA fragmentation index(DFI)is a metric used to assess DNA fragmentation within sperm.During in vitro fertilizationembryo transfer(IVF-ET),high sperm DFI can lead to a low fertilization rate,poor embryo development,early miscarriage,etc.A kinase anchoring protein(AKAP)is a scaffold protein that can bind protein kinase A(PKA)to subcellular sites of specific substrates and protects the biophosphorylation reaction.Sperm protein antigen 17(SPA17)can also bind to AKAP.This study intends to explore the reason for the decreased fertilization rate observed in high sperm DFI(H-DFI)patients during IVF-ET.In addition,the study investigates the expression of AKAP,protein kinase A regulatory subunit(PKARIl),and SPA17 between H-DFI and low sperm DFI(L-DFI)patients.SPA17 at the transcriptional level is abnormal,the translational level increases in H-DFI patients,and the expression of AKAP4/PKARIl protein decreases.H,O,has been used to simulate oxidative stress damage to spermatozoa during the formation of sperm DFI.It indicates that H,O,increases the expression of sperm SPA17 protein and suppresses AKAP4/PKARIl protein expression.These processes inhibit sperm capacitation and reduce acrosomal reactions.Embryo culture data and IVF outcomes have been documented.The H-DFI group has a lower fertilization rate.Therefore,the results indicate that the possible causes for the decreased fertilization rate in the H-DFI patients have included loss of sperm AKAP4/PKARIl proteins,blocked sperm capacitation,and reduced occurrence of acrosome reaction.

Prediction of Th17/Treg cell balance on length of stay in intensive care units of patients with sepsis

Background Prolonged length of stay(LOS)of sepsis can drain a hospital's material and human resources.This study investigated the correlations between T helper type 17(Th17)and regulatory T(Treg)balance with LOS in sepsis.Methods A prospective clinical observational study was designed in Changhai Hospital affiliated to Naval Medical University in Shanghai,China,from January to October 2020.The patients diagnosed with sepsis and who met the inclusion and exclusion criteria were recruited and whether the levels of cytokines,procalcitonin,subtypes,and biomarkers of T cells in the peripheral blood were detected.We analyzed the correlation between these and LOS.Results Sixty septic patients were classified into two groups according to whether their intensive care unit(ICU)stay exceeded 14 days.The patients with LOS≥14 days were older([72.6±7.5]years vs.[63.3±10.4]years,P=0.015)and had higher Sequential Organ Failure Assessment(SOFA)(median[interquartile range]:6.5[5.0–11.0]vs.4.0[3.0–6.0],P=0.001)and higher Acute Physiology and Chronic Health Evaluation(APACHE)II scores(16.0[13.0–21.0]vs.8.5[7.0–14.0],P=0.001).There was no difference in other demographic characteristics and cytokines,interleukin-6,tumor necrosis factor-α,and interleukin-10 between the two groups.The Th17/Treg ratio of sepsis with LOS<14 days was considerably lower(0.48[0.38–0.56]vs.0.69[0.51–0.98],P=0.001).For patients with LOS≥14 days,the area under the receiver operating characteristic curve for the Th17/Treg ratio was 0.766.It improved to 0.840 and 0.850 when combined with the SOFA and APACHE II scores,respectively.Conclusions The Th17/Treg ratio was proportional to septic severity and can be used as a potential predictor of ICU stay in sepsis,presenting a new option for ICU practitioners to better care for patients with sepsis.

Single-cell transcriptomics reveals T-cell heterogeneity and immunomodulatory role of CD4+T native cells in Candida albicans infection

Objective:Candida albicans is a common fungal pathogen that triggers complex host defense mechanisms,including coordinated innate and adaptive immune responses,to neutralize invading fungi effectively.Exploring the immune microenvironment has the potential to inform the development of therapeutic strategies for fungal infections.Methods:The study analyzed individual immune cell profiles in peripheral blood mononuclear cells from Candida albicans-infected mice and healthy control mice using single-cell transcriptomics,fluorescence quantitative PCR,and Western blotting.We investigated intergroup differences in the dynamics of immune cell subpopulation infiltration,pathway enrichment,and differentiation during Candida albicans infection.Results:Our findings indicate that infiltration of CD4^(+)naive cells,regulatory T(Treg)cells,and Microtubules(MT)-associated cells increased after infection,along with impaired T cell activity.Notably,CD4^(+)T cells and plasma cells were enhanced after infection,suggesting that antibody production is dependent on T cells.In addition,we screened 6 hub genes,transcription factor forkhead box protein 3(Foxp3),cytotoxic T-lymphocyte associated protein 4(CTLA4),Interleukin 2 Receptor Subunit Beta(Il2rb),Cd28,C-C Motif Chemokine Ligand 5(Ccl5),and Cd27 for alterations associated with CD4^(+)T cell differentiation.Conclusions:These results provide a comprehensive immunological landscape of the mechanisms of Candida albicans infection and greatly advance our understanding of adaptive immunity in fungal infections.
