ABSTRACT
Objective:To investigate the correlation between plasma microRNA (miR)-122, miR-33a and the severity of coronary artery disease in patients with type 2 diabetes mellitus (T2DM) and coronary heart disease.Methods:The clinical data of 196 patients with T2DM from January 2019 to October 2021 in Xuzhou First People′s Hospital were retrospectively analyzed. Among them, 81 cases were complicated with coronary heart disease (combined group), 115 cases were not complicated with coronary heart disease (control group). The plasma levels of miR-122 and miR-33a were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction, the plasma level of N-terminal B-type natriuretic peptide precursor (NT-proBNP) was detected by enzyme-linked immunosorbent assay. In combined group, the number of coronary artery lesions was determined according to the results of coronary angiography, and Gensini score was evaluated. Linear regression model was used to analyze the relationship between plasma miR-122, miR-33a and NT-proBNP levels with the incidence of coronary heart disease in patients with T2DM. Receiver operating characteristic (ROC) curve was used to analyze the plasma miR-122 and miR-33a in predicting efficiency of coronary heart disease in patients with T2DM. In combined group, Spearman correlation method was used to analyze the relationship between plasma miR-122, miR-33a and the number of coronary artery lesions, and Pearson correlation method was used to analyze the relationship between plasma miR-122, miR-33a and plasma NT proBNP, Gensini score.Results:The plasma miR-122, miR-33a and NT-proBNP in combined group were significantly higher than those in control group: 5.76 ± 1.35 vs. 1.18 ± 0.33, 1.39 ± 0.37 vs. 0.65 ± 0.11 and (786.87 ± 156.39) ng/L vs. (103.45 ± 19.27) ng/L respectively, and there were statistical differences ( P<0.01). Linear regression result showed that plasma miR-122, miR-33a, and NT-proBNP were positive correlation with occurrence of coronary heart disease in patients with T2DM ( P<0.01); ROC curve analysis result showed that the area under curve of plasma miR-122, miR-33a and combination in predicting coronary heart disease in patients with T2DM were 0.816, 0.845 and 0.912 respectively (95% CI 0.744 to 0.865, 0.768 to 0.892 and 0.836 to 0.967). Coronary angiography result showed that there were 46 cases of single vessel lesions, 25 cases of double vessel lesions and 10 cases of three vessel lesions. The plasma miR-122, miR-33a, NT-proBNP and Gensini score in patients with three vessel lesions were significantly higher than those in patients with double vessel lesions and patients with single vessel lesions: 6.52 ± 0.96 vs. 4.95 ± 0.85 and 3.74 ± 0.52, 1.45 ± 0.31 vs. 1.06 ± 0.25 and 0.81 ± 0.13, (829.78 ± 62.59) ng/L vs. (627.48 ± 47.12) and (502.64 ± 38.24) ng/L, (63.89 ± 12.71) scores vs. (42.18 ± 6.03) and (22.36 ± 2.41) scores, the indexes in patients with double vessel lesions were significantly higher than those in patients with single vessel lesions, and there were statistical differences ( P<0.05). In combined group, Spearman correlation analysis result showed that the plasma miR-122 and miR-33a were positive correlation with the number of coronary artery lesions ( r = 0.879 and 0.825, P<0.05); Pearson correlation analysis result showed that the plasma miR-122 and miR-33a were positive correlation with the plasma NT-proBNP and Gensini score (miR-122: r = 0.896 and 0.788, miR-33a: r = 0.871 and 0.765; P<0.05). Conclusions:The plasma levels of miR-122 and miR-33a are related to the occurrence of coronary heart disease and severity of coronary artery disease in patients with T2DM, which may be used to guide the prevention and treatment of coronary heart disease in patients with T2DM.
ABSTRACT
Objective:To investigate the safety and feasibility of endoscopic level V lymph node dissection for thyroid cancer.Methods:Two cases undergoing level V lymph node dissection via breast combined with oral approach for papillary thyroid cancer in May. 2021 and Sep.2021 were retrospectively analyzed. The primary thyroid lesions and metastatic lymph nodes were diagnosed pathologically by fine needle aspiration before operation. The routine examination such as ultrasound, CT and laryngoscopy were completed before operation.Results:Both operations were successfully completed under endoscopy. In case 1, one lymph node was found in neck V region, and no metastatic lymph node was found. In case 2, 7 lymph nodes were found in cervical V region. No "shoulder syndrome" encompassing shoulder dysfunction and pain was found in either case.Conclusions:The study on the two cases reveals that level V dissection after the routine operation of endoscopic central and lateral neck dissection via breast combined with oral approach for papillary thyroid cancer is feasible and safe. More cases in further study were needed for to verify the finding.
ABSTRACT
Objective:To analyze the risk factors of the number of central lymph node metastasis (CLNM) >5 in papillary thyroid microcarcinoma (PTMC) with clinical lymph node negative (cN0) .Methods:A total of 1567 cases of unilateral cN0 PTMC patients undergoing surgery at Endocrine and Breast Surgery Department of the First Affiliated Hospital of Chongqing Medical University from Jan. 2013 to Dec. 2018 were analyzed retrospectively. There were 405 cases of male and 1162 cases of female among them. According to the CLNM, they were divided into 0-5 and ≥5 groups. Clinicopathological characteristics of two groups were compared with Chi-square test and χ 2 test, et al. Results:The case of CLNM>5 involved was 4.1% (65/1567) .Univariate analysis showed that male, age ≤50 years old, tumor diameter> 8 mm, multifocal cancer all were related to CLNM>5 involved ( P<0.05) , multivariate logistic regression analysis found that male ( OR=1.886, P=0.017) , age ≤50 years ( OR=3.778, P=0.002) , tumor diameter>8 mm ( OR=2.483, P<0.001) and multifocal cancer ( OR=2.362, P=0.005) were independent risk factors for CLNM>5. Subgroup analysis showed that the number of Delphian lymph nodes metastasis≥1 ( OR=13.475, P<0.001) , pretracheal lymph nodes metastasis≥2 ( OR=41.695, P<0.001) , and Delphian+pretracheal lymph nodes metastasis≥2 ( OR=28.750, P<0.001) were also independent risk factors for CLNM>5. Conclusions:Unilateral PTMC patients who are male and age ≤50 years old with tumor diameter>8 mm, multifocal cancer have higher risk of central lymph nodes more than 5 involved, surgical treatment and prophylactic central neck dissection are recommended to such patients instead of long-term follow-up observation.Total thyroidectomy should be selected appropriately according to the intraoperative situation.
ABSTRACT
Objective:To investigate the molecular epidemiological characteristics and antibiotic resistance of Clostridioides difficile ( Cd) in hospitalized diarrhea patients in a tertiary hospital in Shaanxi Province. Methods:This study collected 425 stool samples of hospitalized diarrhea patients from October 2018 to December 2021 for isolation and identification of Cd. Toxin genes carried by the isolates were detected. Multilocus sequence typing (MLST) was performed to analyze the phylogenetic profile. Antibiotic susceptibility was analyzed by E-test. Results:Forty-nine strains of Cd were isolated from the 425 samples, including 37 strains of toxigenic Cd (75.5%, 37/49). The detection rate of Cd was 14.0% (25/179) in diarrhea patients aged ≥65 years old and 36.4% (4/11) in Nephrology Department. In the 37 toxigenic Cd strains, A -B + CDT -Cd, A + B + CDT -Cd and A + B + CDT +Cd accounted for 18.9% (7/37), 78.4% (29/37) and 2.7% (1/37), respectively. There were 24 ST types, among which ST2, ST3 and ST54 were the predominant types, each accounting for 12.2% (6/49). All strains were sensitive to metronidazole and vancomycin, with a high resistance rate of 93.9% (46/49) to ciprofloxacin and a low resistance rate of 12.2% (6/49) and 10.2% (5/49) to rifampicin and meropenem, respectively. Conclusions:The main type of toxigenic strains was A + B + CDT -. ST2, ST3 and ST54 were the predominant types and the distribution of ST types was scattered. All isolates were sensitive to metronidazole and vancomycin and most of them were resistant to ciprofloxacin.
ABSTRACT
Clostridioides difficile infection (CDI) is an infectious disease with fever, abdominal pain and diarrhea as the main clinical manifestations. At present, CDI is mainly treated with antibiotics and faecal microbiota transplantation. As recurrent and refractory CDI continues to increase, it is important to seek a more effective alternative therapy. However, many of the studies on the prevention and control of CDI by probiotics are still in the early stage. This paper summarized the research on the types, mechanisms and technical means of probiotics in the treatment of CDI.
ABSTRACT
Cardiovascular diseases have become a major cause of disability and death among the elderly in China.The continuous improvement of medical care has provided effective treatment for elderly patients with cardiovascular diseases in the acute phase, while how to improve the quality of life and prognosis of patients in the chronic phase has become a medical imperative to be solved.Cardiac rehabilitation, with exercise rehabilitation at its core, is expected to improve cardiopulmonary function, enhance exercise tolerance, alleviate anxiety and depression, and reduce mortality and rehospitalization rates, and has therefore become an effective intervention for cardiovascular diseases in the elderly.In the light of special concerns for the elderly population, such as cognitive impairment, frailty, sarcopenia and polypharmacy, this article systematically introduces the characteristics, obstacles and clinical strategies of cardiac rehabilitation for geriatric cardiovascular diseases, in an effort to provide a clinical reference guide for geriatric cardiac rehabilitation.
ABSTRACT
Objective:To analyze the labor progression characteristics of primiparous term singleton pregnant women with adenomyosis.Methods:From April 2014 to May 2021, pregnant women underwent regular antenatal examination in Peking University Third Hospital were enrolled in this retrospective study, 109 primiparous term pregnant women with adenomyosis who underwent singleton, primipara, cephalic and vaginal delivery were referred as the adenomyosis group, while 109 pregnant women without adenomyosis primiparous term pregnant women at the same time were referred as the control group. The general clinical information, labor process intervention, pregnancy outcomes and labor course time of the two groups were analyzed.Results:(1) General clinical conditions: the pre-pregnancy uterine volume of the adenomyosis group was larger than that of the control group [(66.8±23.7) vs (41.4±13.1) cm 3, P<0.05]. The proportion of assisted reproductive pregnancy and endometriosis in the adenomyosis group were higher than those in the control group [31.2% (34/109) vs 7.3% (8/109); 31.2% (34/109) vs 5.5% (6/109); all P<0.05]. There were no significant differences in maternal age, gestational age at delivery, pre-pregnancy body mass index, gestational weight gain, gravidity, incidence of pregnancy complications (gestational diabetes mellitus, pre-eclampsia and thyroid diseases) and premature rupture of membranes between the two groups (all P>0.05). (2) Labor process intervention and maternal and fetal outcomes: postpartum hemorrhage was higher in the adenomyosis group than the control group (median: 300 vs 260 ml, P=0.018). There were no significant differences in the proportion of labor onset, use of oxytocin, artificial rupture of membranes, perineal laceration Ⅲ and above, episiotomy, newborn weight and 1-minute Apgar score between the two groups (all P>0.05). (3) Time of labor process: there were no significant differences between the two groups in the time required for the first stage, third stage, total stage and cervical dilation 0-1, 1-2, 2-3, 3-4, 4-5, 5-6, 6-7 cm (all P>0.05). The time required for cervical dilation 7-8, 8-9, 9-10 cm and the second stage of labor in adenomyosis group (median: 20, 18, 15 and 12 minutes, respectively) were shorter than those of the control group (median: 23, 23, 23 and 26 minutes, respectively), and the differences were statistically significant (all P<0.05). (4) The effect of endometriosis on labor: there was no significant difference in the effect of endometriosis on labor in adenomyosis group ( P>0.05). Conclusions:The labor process of primiparous term pregnant women with adenomyosis is significantly accelerated after the cervical dilatation for 7 cm, which should be closely observed. The third stage of labor course is managed aggressively with drugs to prevent postpartum hemorrhage.
ABSTRACT
The assessment and treatment of neurodevelopment abnormalities in fetuses with growth restriction have become a focus and challenge in recent years. We review the recent advances in this field, including the imaging assessment (diffusion-weighted imaging, diffusion tensor imaging, and phase-control MRI), predictive value of biomarkers (S100B, glial fibrillary acidic protein, and myelin basic protein), and the treatment of brain injury (antioxidant therapy, oxytocin receptor agonists, and melatonin) in these fetuses, aiming to provide a reference for intrauterine monitoring and treatment.
ABSTRACT
ObjectiveTo conduct genetic variation analysis of 11 cultivars and 7 wild populations of Angelica sinensis in Gansu province based on the chloroplast gene （cp DNA）， and provide references for germplasm identification and breeding of new cultivars of A. sinensis. MethodThree pairs of cp DNA primers were used for polymerase chain reaction （PCR） amplification and sequencing of A. sinensis samples. MegaX was used to perform statistics on sequence characteristics and calculate mean genetic distances among A. sinensis populations. Unweighted pair-group method with arithmetic means （UPGMA） clustering tree based on genetic distance was constructed by NTSYS 2.10e. DanSP v6 was used to calculate sequence polymorphism and Tajima's D of A. sinensis. PERMUT was used to calculate the population structure of A. sinensis. Arlequin v3.5 was used to perform molecular variation analysis， and PopART1.7 was used to construct TCS haplotype network. ResultThree pairs of cp DNA primers were amplified， sequenced， compared， and combined to give a sequence length of 1 759 bp. One variable site was detected in the wild A. sinensis and 480 variable sites were detected in the cultivated A. sinensis， including 97 singleton variable sites， 383 parsimony informative sites， and 152 insertion-deletion sites. In the three regions of matK， psbA-trnH， and rbcL of cp DNA in the wild and cultivated A. sinensis， matK was the region with the highest polymorphism. Tajima’s D of all the combined sequences of A. sinensis were not significantly negative， but psbA-trnH and rbcL genes of the cultivated A. sinensis were significantly negative， indicating that the A. sinensis followed neutral evolution on a whole， while psbA-trnH and rbcL genes had undergone selection. The degree of genetic differentiation （Fst=0） among wild populations was lower than that among cultivated populations （Fst=0.114 19， P<0.05）. The degree of genetic differentiation between wild and cultivated A. sinensis was relatively high （Fst=0.942 55， P<0.01）. Genetic variation in the cultivated A. sinensis was mainly found within the populations （89%）. UPGMA cluster tree based on genetic distance showed that the wild A. sinensis and the cultivated A. sinensis were clustered into one branch， respectively， with a distant genetic relationship， and the population 3 in the cultivated A. sinensis was far from other cultivated populations. The TCS haplotype network consisted of 15 haplotypes and 4 unknown haplotypes， which was divided into 3 parts， with a large number of variations among each part. Shared haplotypes were only found in the wild or cultivated groups， and there were no shared haplotypes between groups. ConclusionThe genetic diversity of A. sinensis was low at species level， and the population diversity of the wild was lower than that of the cultivated. The degree of genetic differentiation between the wild and the cultivated A. sinensis was high， but that in the wild and the cultivated populations were low. Genetic variation in the cultivated A. sinensis was mainly found within populations.
ABSTRACT
Gastrointestinal mucositis is one of the most debilitating side effects of the chemotherapeutic agent irinotecan (CPT-11). Andrographolide, a natural bicyclic diterpenoid lactone, has been reported to possess anti-colitis activity. In this study, andrographolide treatment was found to significantly relieve CPT-11-induced colitis in tumor-bearing mice without decreasing the tumor suppression effect of CPT-11. CPT-11 causes DNA damage and the release of double-stranded DNA (dsDNA) from the intestine, leading to cyclic-GMP-AMP synthase (cGAS)‒stimulator of interferon genes (STING)-mediated colitis, which was significantly decreased by andrographolide both in vivo and in vitro. Mechanistic studies revealed that andrographolide could promote homologous recombination (HR) repair and downregulate dsDNA‒cGAS‒STING signaling and contribute to the improvement of CPT-11-induced gastrointestinal mucositis. These results suggest that andrographolide may be a novel agent to relieve gastrointestinal mucositis caused by CPT-11.
ABSTRACT
Objective:To assess the reliability, constructive validity and item characteristics of the general self-efficacy scale (GSES) among Chinese medical postgraduates using classical test theory and item response theory.Methods:A questionnaire survey was conducted among 1 021 medical postgraduates from 6 comprehensive level Ⅲ A hospitals in Beijing. Demographic characteristics and general self-efficacy were investigated. SPSS 24.0 software was used for statistical analysis. Internal consistency of the GSES was evaluated using Cronbach’s α coefficient and intraclass correlation coefficient. Factor analyses were implemented to test the structure of the scale. An item response theory (IRT) framework with a graded response model was performed to estimate the parameters of each item. Results:The overall Cronbach’s α coefficient of the GSES was 0.92. Parallel analysis and confirmatory factor analysis supported the unidimensional structure of the GSES. The discrimination parameter of the 10 items ranged from 1.82 to 3.65, and the difficulty parameter ranged from -3.51 to 1.66, with a monotonically increasing trend. The maximum test information of the scale among medical postgraduates was 19.16. Conclusion:The GSES has good reliability, validity and measurement precision, showing a good applicability in the survey of medical postgraduates. However, the difficulty of specific items is relatively low, and the scale may be further optimized and improved.
ABSTRACT
Objective:To investigate the effects of hypertensive disorders during pregnancy (HDP) on preterm newborns in terms of umbilical cord blood serum ferritin (SF), hemoglobin (Hb) at birth and outcome.Methods:Among inpatients of the First Maternity and Infant Health Hospital Affiliated to Tongji University from October 1, 2015 to December 31, 2016, totally 1 419 cases of preterm newborns were prospectively collected.Preterm infants whose mothers with diagnosis of HDP were recruited as the HDP group.Meanwhile, premature newborns whose mothers without HDP were recruited as the control group.Umbilical cord blood SF levels, Hb levels at birth, outcome of preterm newborns and the basic information for maternity were compared between the two groups.The data of normal distribution between the two groups were compared by independent sample t test.The count data was tested by χ2, and the count data with frequency <5 was tested by Fisher′ s exact test. Results:SF levels of HDP group were significantly lower than the control group [(85.6±67.2) μg/L vs. (103.9±95.5) μg/L]. But Hb levels of HDP group were much higher than the control group [(206.2±33.8) g/L vs. (193.2±31.9) g/L]. The difference between two groups was statistically significant ( t=2.791, 4.825 all P<0.05). Umbilical cord blood SF levels were negatively correlated with Hb levels at birth ( r=-0.120, P<0.001). Moreover, compared to the control group, statistically significant lower incidence of neonatal respiratory distress syndrome (NRDS), pneumonia and bronchopulmonary dysplasia (BPD) in HDP group was observed (all P<0.05). Conclusions:HDP was correlated with umbilical cord blood SF levels and Hb levels at birth in premature newborns.Higher Hb levels and relatively lower incidences of NRDS, pneumonia and BPD were observed in these newborns delivered by mothers with diagnosis of HDP.
ABSTRACT
Objective:To investigate the immediate and lasting effects of enhanced external counterpulsation(EECP)on blood pressure in elderly patients with hypertension.Methods:In this real-world prospective non-randomized controlled study, the elderly hypertensive patients who were newly diagnosed as hypertension or had poor blood pressure control in the Geriatrics Department of Shandong University Qilu Hospital from May 2019 to December 2019, were enrolled as EECP group, and those with systolic blood pressure(SBP)≥180mmHg(1mmHg=0.133 kPa)or had contraindications for EECP treatment were excluded from EECP group(28 cases). Based on the 1∶1 ratio being consistent with the tendency score-matching method, patients' blood pressure was matched at 3 d before the start of the EECP treatment course, with other matched data of baseline data, coexisting disease, cardiovascular medication were choosed as control group(n=28). The EECP group received an additional 36 hours of EECP treatment(6 times/week, 1 hour/time)including lifestyle improvement and anti-hypertensive drugs.The patient's supine blood pressure was collected 3 minutes before each EECP treatment(baseline), 30 minutes during treatment, and 3 minutes after treatment.In the EECP group, family self-measured blood pressure was collected 3 days before the start of the 6-week treatment course(0w), the 6th week(6w)of the treatment course, and the 2nd week(+ 2w), 4th week(+ 4w)and 12th week(+ 12w)after the end of the treatment course, respectively.And the data of control group were collected at the same time point mentioned above.Results:Compared with baseline, the average immediate SBP of elderly hypertensive patients at the 30th minute of EECP treatment was decreased by(5.5±13.6)mmHg( P<0.001), and the average immediate diabolic blood pressure(DBP)was decreased by(1.1±7.5)mmHg( P<0.001). When the baseline SBP was between 160 and 169 mmHg, the probability of a further increase in SBP during treatment was 2.2%(2/89 cases), and when the baseline SBP was between 170 and 179 mmHg, the probability of a further increase in SBP during treatment was 0%(0/57). At 6 weeks, the decrease in SBP was significantly greater in the EECP group than in the control group[(-17.0±8.7)mmHg vs.(-10.5±7.3)mmHg, P<0.01], and the difference continued to + 2w[(-15.5±6.6)mmHg vs.(-10.6±2.5)mmHg, P<0.01]and + 4w[(-13.3±5.4)mmHg vs.(-10.7±2.1)mmHg, P<0.05]. At + 12w, the blood pressure drop was still greater in EECP group than in the control group, but it did not achieve statistically significant differences.Smoking history, history of diabetes, family history of hypertension, and improvement of comorbidities were the key factors that affect the continuous anti-hypertensive effect of EECP. Conclusions:EECP treatment has an immediate effect on lowering blood pressure in elderly hypertensive patients.A 6-week course of EECP treatment has a sustained effect on lowering blood pressure, and the effect can last from 4 to 12 weeks after the end of the course of treatment.
ABSTRACT
Objective:To explore the training methods to improve the cosmetic suture technique of junior surgeons.Methods:The training course of cosmetic suture techniques was carried out for junior residents such as plastic surgery professional graduate students and standardized training residents, through the study of the basic knowledge of cosmetic suture and the practical training of minimally invasive principles, to help them master cosmetic suture techniques systematically for the need of future clinical practice. Compared with the level of operation skills before and after cosmetic suture training in different groups (graduate students of plastic surgery and other majors, standardized training residents of plastic surgery and other majors), the residents' performance had been significantly improved. The incisions healing after half a year follow-up in cases they sutured were observed.Results:After cosmetic suture training, the suture skills of the students were significantly improved, and there was a significant correlation with the time of clinical practice. The incidence of incisions inflammation and postoperative scar formation in the cases sutured by the students with practice for 6 months was significantly lower than those for 1 month (6.42% vs 21.67%, 1.13% vs 5.56% respectively).Conclusions:The training of cosmetic suture techniques is very important to improve the professional ability of junior residents in plastic and cosmetic surgery, and it needs a long time practice to master the suture skills.

Conclusion:Heating replacement fluid by 3M blood warming device is proved to be the best way to prevent heat loss in CRRT treatment.
ABSTRACT
OBJECTIVE：To explore the role of clinical pharmacists in the diagnosis and tre atment of immune checkpoint inhibitor related adrenocortical insufficiency ，so as to provide reference for the diagnosis and treatment of similar cases. METHODS：A lung squamous carcinoma patient with tumor immunotherapy ，who received long-term intravenous infusion of Pembrolizumab injection ，was hospitalized for more than 10 days due to fatigue and poor appetite. The clinical pharmacists consulted the literature and evaluated the correlation of ADR on the basis of patient ’s physical examination results （plasma cortisol 16.41 nmol/L at 8：00 in the morning on the second day of admission ，adrenocorticotropic hormone 8.39 pg/mL，serum electrolyte sodium 126.00 mmol/L，chlorine 88.00 mmol/L，etc.）and medication history （receiving the treatment with immune checkpoint inhibitors）. The clinical pharmacists assisted the doctor to confirm that the patient was adrenocortical insufficiency ，and the correlation with pembrolizumab was “very likely ”. On the basis of discontinuation of pembrolizumab ，it was recommended to take Hydrocortisone tablets orally （20 mg at 8：00 in the morning and 10 mg at 4：00 in the afternoon ）for glucocorticoid physiological dose substitution therapy. Before treatment ，the patient and his families should be educated on the use of drugs ，pharmaceutical care should be implemented to evaluate the glucocorticoid doseand efficacy during treatment ，and medication education was carried out at discharge. RESULTS ：The doctor adopted theli_xyan suggestions of the clinical pharmacist. On the 5th day after @126.com administration，the symptoms of adrenocortical insufficiency were significantly impro ved，and the patient was discharged with medicine. CONCLUSIONS ：During the treatment of the patient ， the clinical pharmacist gave full play to his pharmaceutical expertise ，assisted the doctor to formulate an appropriate medication plan，and carried out medication education for the patient and his family members ，so as to ensure the effectiveness and safety of the patient ’s medication. It is suggested that the baseline examination of patients should be improved before immune checkpoint inhibitor treatment ，including physical examination and plasma cortisol level at 8：00 in the morning ；the frequency of monitoring plasma cortisol level and serum electrolyte level at 8：00 in the morning. should be increased during medication ；the patients should be followed up for at least 1 year after withdrawal ，so as to early detect and treat immune checkpoint inhibitor related adrenocortical dysfunction.
ABSTRACT
Objective:To explore the predictive value of a scoring model based on MRI images for diagnosing invasive placenta accreta and associated adverse clinical outcomes.Methods:This retrospective cohort study involved 260 patients delivered at Peking University Third Hospital from January 2015 to December 2018, who were suspected to be placenta accreta with two or more ultrasound image findings and underwent MRI examination. Placenta accreta was finally diagnosed and classified based on the intraoperative clinical findings or pathological examination. Adverse clinical outcomes were defined as intraoperative bleeding ≥1 500 ml and/or having hysterectomy. Quantitative and qualitative interpretation of five MRI signs were performed, including intraplacental low-intensity band on T2 weighted imaging, abnormal intraplacental vascularization, vascularization of uterovesical interface, uterine bulging and cervical involvement. Chi-square and t test were used for univariate analysis of the five MRI signs and the receiver operating characteristics (ROC) curve of each MRI sign for predicting invasive placenta accreta and adverse clinical outcomes were drawn. The predictive value was assigned as 1 when ≥ the cutoffs that matched to the maximum Yoden index values, and was assigned as 0 when below the cutoffs. A scoring model based on the five MRI signs was established, ROC curves of the model for predicting invasive placenta accreta and adverse clinical outcomes were drawn and the area under the curve (AUC), sensitivity, specificity and Youden index were calculated. Results:(1) Univariate analysis showed that all five MRI signs were significantly associated with invasive placenta accreta and adverse clinical outcomes. Except for cervical involvement, the other four signs had an AUC value of greater than 0.5 in predicting invasive placenta accreta and adverse clinical outcomes. (2) The predictive cut-off values of abnormal intraplacental vascularization image and intraplacental dark band area on T2 weighted imaging were 2.0 cm 2 and 0.6 cm 2, respectively, and were all 1.0 for the other three signs. The AUC value of MRI signs-based scoring model for predicting invasive placenta accreta was 0.863. When the score was ≥ 2 points, the diagnostic sensitivity was 0.836 and the specificity was 0.726. The scoring model predicted adverse clinical outcomes with an AUC of 0.841. When the score was ≥3 points, the predictive sensitivity was 0.707 and the specificity was 0.818. Conclusions:The scoring model based on MRI signs is of good value for the diagnosis of invasive placenta accreta and the prediction of adverse clinical outcomes.
ABSTRACT
Primary age-related tauopathy (PART) is one of neurodegenerative diseases in the very old people. PART clinically resembles Alzheimer′s disease and its definite diagnose needs pathological identification of neurofibrillary tangles with or without amyloid plaques in the brain. This article reviews the historical evolution, clinical manifestation, pathology and diagnosis of PART in order to provide new insights.
ABSTRACT
Objective:To investigate the effect of enhanced external counterpulsation(EECP)on heart failure with preserved ejection fraction(HFpEF)and hemodynamics in elderly patients.Methods:Clinical data of 66 elderly HFpEF patients admitted to the enhanced external counterpulsation center of our hospital from January 2018 to December 2019 were retrospectively analyzed.The primary assessment parameter was the six-minute walk distance, and the secondary parameters included the Minnesota Living with Heart Failure Questionnaire(MLHFQ). Noninvasive hemodynamic parameters including the cardiac index(CI), stroke volume(SV), isovolumic relaxation period(A2-mitral valve opening, A2-O), pulmonary capillary wedge pressure(PCWP)and total peripheral resistance(TPR)were monitored and mean arterial blood pressure(MAP)was calculated.Results:After EECP treatment, the six-minute walk distance increased(372±87 m vs.341±85 m, P<0.05), the score of MLHFQ decreased(47.0±16.0 vs.50.0±17.0, P<0.05), CI increased(2.8±0.7)L·min -1·m -2vs.(2.6±0.6)L·min -1·m -2( P<0.05), SV, PCWP and A2-O did not show significant change(73.3±16.4 ml vs.71.5±17.1 ml, 10.0±3.3 mmHg vs.11.0±3.6 mmHg, 1 mmHg=0.133 kPa, 98.0±29.5 ms vs.91.0±29.1 ms, P>0.05), TPR decreased(1 719.0±427.0 DS/cm 5vs.1 821.0±508.0 DS/cm 5, P<0.05), and there was no significant change in MAP(96.9±10.7 mmHg vs.98.8±13.1 mmHg, P>0.05), compared with pre-EECP treatment levels.Compared with patients without hypertension, MAP decreased in patients with hypertension(14 cases), when stratified by the initial MAP( P<0.05). Conclusions:For elderly patients with HFpEF, EECP can increase the six-minute walk distance, improve the quality of life and hemodynamic parameters, and is a safe adjuvant treatment.
