ABSTRACT

Background A large amount of iron deposition in the brain can cause neuronal damage by inducing oxidative stress, neuroinflammation, and abnormal mitochondrial function. In addition, iron deposition is also reported to be closely related to the pathogenesis of Alzheimer's disease (AD). The neurofibrillary tangles aggregated by tau hyperphosphorylation are one of the important pathological features of AD. Objective To investigate potential effect of exogenous trivalent iron ions on neuronal activity in human neuroblastoma (SH-SY5Y) cells and tau hyperphosphorylation and aggregation. Methods SH-SY5Y cells were treated with ferric chloride (FeCl3) at four concentrations (10, 100, 200, and 400 mg·L−1). Cell survival rate was then detected by CCK8 assay. Intracellular iron content was determined prussian blue (Perl's) by iron staining after 24 h exposure to FeCl3 at 10 or 200 mg·L−1. Transfection of tau-P301L plasmid was conducted to construct an AD-like cell model for tau overexpression. The differences in the expression of the phosphorylated tau (p-tau) protein in SH-SY5Y cells and SH-SY5Y cells with tau overexpression were detected by Western blotting after 24 h exposure to FeCl3 at 10 and 200 mg·L−1. After dilution with phosphate buffered saline (PBS), FeCl3, human tauR3, and FeCl3 + tauR3 were incubated at 37℃, and the fluorescence intensity reflecting tau aggregation level was measured by thioflavin T(ThT) method at 12, 24, 36, 48, 60, 72, 84, and 96 h, respectively. Meanwhile, after 96 h coincubation of FeCl3 and tauR3, the fibers formed by tau aggregation were observed under a transmission electron microscope (TEM). Results After 24 h of FeCl3 exposure, the cell survival rate of SH-SY5Y cells among all groups was statistically different (F=8.63, P<0.01). The cell survival rates in the 200 and 400 mg·L−1 groups were 80.1% and 68.7% of the control group, respectively (P<0.05). Compared with the control group, the nuclei of the 200 mg·L−1 FeCl3 group were mainly yellowish-brown after iron staining and the positive cell rate was up-regulated by 12.9% (P<0.01). After 24 h of FeCl3 exposure , the p-tau (Ser396) protein expression was statistically different among all groups (F=11.6, P<0.01). Compared with the control group, the p-tau protein expression level of SH-SY5Y cells in the 200 mg·L−1 group was up-regulated by 72.7% (P<0.01). After FeCl3-treated SH-SY5Y cells with tau overexpression for 24 h, the p-tau (Ser396) protein expression was statistically different among all groups (F=27.8, P<0.01). Compared with the tau group, the p-tau (Ser396) protein expression level of SH-SY5Y cells in the tau + 200 mg·L−1 group was up-regulated by 44.6% (P<0.05). Compared with the tauR3 group, the fluorescence intensities in the 84 and 96 h tauR3 + FeCl3 groups were up-regulated by 49.9% and 53.7% (P<0.01) respectively. After 96 h of coincubation, compared with the tauR3 group, FeCl3 + tauR3 aggravated tau aggregation and formed fiber deposition under TEM. Conclusion Exogenous trivalent iron ions may inhibit SH-SY5Y cell viability, promote the phosphorylation of tau in SH-SY5Y cells transfected with tau-P301L plasmid, and aggravate tauR3 aggregation and fiber production.

ABSTRACT

Objective:To explore the role of continuous renal replacement therapy (CRRT) combined with extracorporeal carbon dioxide removal (ECCO 2R) in the treatment of children with respiratory failure. Methods:The clinical data of 12 children with respiratory failure who were treated with CRRT+ECCO 2R in PICU of Jinan Children's Hospital from July 2020 to August 2022 were collected and analyzed retrospectively. The outcomes and the external pipeline usage of the patients were observed, and the blood gas analysis and ventilator parameters before 1 h and after 1, 6, 12 and 24 h of the treatment were compared by one-way ANOVA with LSD post hoc correction. Results:Six patients successfully withdrew from CRRT+ECCO 2R and mechanical ventilation, three patients were transferred to ECMO treatment. Three cases died after voluntary withdrawal of treatment, and two cases died due to treatment failure. The mortality rate was 41.7%. After continuous treatment of CRRT+ECCO 2R for 15 to 112 h, two cases experienced extracorporeal circuit obstruction. After 1 h of treatment, PaCO 2 decreased from (64.67±24.4) mmHg to (49.42±15.54) mmHg, pH increased from (7.28±0.20) to (7.38±0.11), FiO 2 decreased from (0.85±0.13) to (0.78±0.15), PC decreased from (19.42±4.34) cmH 2O to (17.75±4.00) cmH 2O. After 24 h of treatment, PaCO 2 decreased to (39.2±5.55) mmHg, pH increased to (7.41±0.04), FiO 2 decreased to (0.46±0.11), and PC decreased to (13.8±3.36) cmH 2O, and the differences were statistically significant compared with before treatment ( P < 0.05). Conclusions:The combination of CRRT and ECCO 2R therapy can safely substitute for partial lung ventilation/perfusion function, and play a role in protecting right heart function and improving lung-kidney interaction. It can be considered as an option for extracorporeal respiratory, circulatory, and renal support, and consequently has broad prospects.

ABSTRACT

Chronic myeloid leukemia (CML) is a malignant hematological disease driven by BCR-ABL fusion protein. The emergence of tyrosine kinase inhibitor (TKI) targeting BCR-ABL has completely changed the treatment pattern of CML. From the approval of the first generation TKI imatinib in 2001 to the emergence of the fourth generation TKI drugs, CML patients have benefited a lot from it. But even so, many CML patients suffer treatment failure due to drug resistance, relapse after drug withdrawal or disease progression, some patients therefore are difficult to obtain long-term remission and still need multi-line TKI treatment. The research and development of new drugs covering more mutation lineages, more optimized treatment strategies and drug withdrawal-related research are still the focus of CML treatment. This article introduces the research progress of CML reported on the 64th American Society of Hematology annual meeting.

ABSTRACT

Periodontitis is an infectious disease caused by an imbalance between the local microbiota and host immune response. Epidemiologically, periodontitis is closely related to the occurrence, development, and poor prognosis of T2D and is recognized as a potential risk factor for T2D. In recent years, increasing attention has been given to the role of the virulence factors produced by disorders of the subgingival microbiota in the pathological mechanism of T2D, including islet β-cell dysfunction and insulin resistance (IR). However, the related mechanisms have not been well summarized. This review highlights periodontitis-derived virulence factors, reviews how these stimuli directly or indirectly regulate islet β-cell dysfunction. The mechanisms by which IR is induced in insulin-targeting tissues (the liver, visceral adipose tissue, and skeletal muscle) are explained, clarifying the influence of periodontitis on the occurrence and development of T2D. In addition, the positive effects of periodontal therapy on T2D are overviewed. Finally, the limitations and prospects of the current research are discussed. In summary, periodontitis is worthy of attention as a promoting factor of T2D. Understanding on the effect of disseminated periodontitis-derived virulence factors on the T2D-related tissues and cells may provide new treatment options for reducing the risk of T2D associated with periodontitis.

ABSTRACT

Objective:To investigate the risk factors for the occurrence and poor in-hospital prognosis in patients with peripartum cardiomyopathy (PPCM).Methods:The clinical data of 35 patients with PPCM and 35 healthy pregnant women in Xuanwu Hospital, Capital Medical University and Beijing Friendship Hospital Affiliated to Capital Medical University from January 2003 to January 2022 were retrospectively analyzed. The personal histories, laboratory examination, imaging examination, cardiac function outcome, etc were collected. According to the left ventricular ejection fraction (LVEF) at discharge, the patients with PPCM were divided into in-hospital recovery group (LVEF≥50%, 18 cases) and prolonged disease group (LVEF<50%, 17 cases). Multivariate Logistic regression analysis was used to analyze independent risk factors of poor in-hospital prognosis in patients with PPCM.Results:Among 35 patients with PPCM, the age was (29.81 ± 5.37) years old, 17 cases (48.57%) complicated with gestational hypertension, 6 cases (17.14%) complicated with gestational diabetes mellitus, 24 cases (68.57%) of New York Heart Association (NYHA) cardiac function classification was Ⅲ to Ⅳ class, and 4 cases died (11.43%). The gestational age in patients with PPCM was significantly shorter than that in healthy pregnant women: (36.26 ± 4.27) weeks vs. (38.54 ± 4.59) weeks, the rates of multiple pregnancy and gestational hypertension were significantly higher than those in healthy pregnant women: 17.14% (6/35) vs. 2.86% (1/35) and 48.57% (17/35) vs. 11.43% (4/35), and there were statistical differences ( P<0.05 or <0.01). Compared with hospital recovery group, the patients in protracted disease group had shorter gestational age, larger left ventricular end-diastolic diameter, higher serum creatinine, C-reactive protein and amino-terminal pro-brain natriuretic peptide (NT-proBNP), worse NYHA cardiac function classification, and there were statistical differences ( P<0.05 or <0.01); but there were no statistical difference in LVEF at the first diagnosis and troponin I between two groups ( P>0.05). Multivariate Logistic regression analysis result showed that elevated creatinine was an independent risk factor for poor in-hospital prognosis in patients with PPCM ( OR = 4.554, 95% CI 1.536 to 13.684, P = 0.018). Conclusions:The gestational hypertension may be a risk factor for PPCM. The gestational hypertension, earlier onset time, enlarged left ventricular end-diastolic diameter, high NT-proBNP, high C-reactive protein, high creatinine and high cardiac function NYHA classification may be risk factors for poor in-hospital prognosis in patients with PPCM; and elevated creatinine is an independent risk factor for poor in-hospital prognosis in patients with PPCM.

ABSTRACT

Objective:To construct and verify a model of excessive medical behavior clues enrichment, for the technical support for the safe and rational use of medical insurance fund.Methods:A model of excessive medical behavior clues enrichment was constructed by the rank assignment method. The inpatient transaction records of medical insurance for employees and residents in 5 tumor hospitals in Beijing from 2016 to 2019 were obtained to verify the validity of the model. The patients were grouped according to age and gender, and each transaction record was converted into a standardized score V(0-100 scores), all transactions were divided into 22 groups according to V value. The Cochran-Armitage trend test was used to analyze the variation trend of enrichment rate with the increase of V value. Chi-square test was used to compare the chargeback rates of different groups. The correlation between the standardized score V and the amount of chargeback was tested by Pearson.Results:There were 872 599 and 86 356 hospitalization transactions for employee and resident medical insurance patients, with included 1 164 and 103 chargeback records respectively. The average score and median of V-value of employee and resident medical insurance transactions were scores of 49 and 50 respectively.When V>0, the enrichment rates of the employee and resident medical insurance were on the rise with the increasing of V( Z=23.86, P<0.001; Z=11.02, P<0.001), the refusal rates among different groups was significant different( χ2=1 307.16, P<0.001)and the correlation between V value and the chargeback amount was statistically significant( r=0.29, P<0.001; r=0.30, P=0.003). Conclusions:This study established a clue enrichment model of excessive medical behavior based on the rank assignment method. By analyzing a large number of medical insurance transaction records, the model can focus on the medical insurance transaction with suspected excessive medical treatment behavior, and has a certain guiding role in the management of medical insurance fund.

ABSTRACT

Objective:To observe the incidence and risk factors of acute kidney injury (AKI) in patients with acute myocardial infarction (AMI), and explore the effect of AKI on the adverse cardiovascular events during hospitalization.Methods:The clinical data of 1 286 first-episode patients with AMI from December 2014 to December 2017 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. The basic information, laboratory test results and used drug were collected, the incidences of AKI and adverse cardiovascular events during hospitalization were recorded.Results:Among 1 286 patients with AMI, 113 cases had AKI, the incidence of AKI was 8.79%. There were statistical differences in gender composition, age, Killip classification>1 grade, hypertension, diabetes, smoking history, left ventricular ejection fraction (LVEF)<56%, baseline estimated glomerular filtration rate (eGFR)<71.5 ml/(min·1.73 m 2), global registry of acute coronary events score (GRACE score) ≥176 scores, hemoglobin<128 g/L, interleukin-6 (IL-6) ≥35.74 ng/L, brain natriuretic peptide (BNP) ≥981 ng/L, thrombolysis in myocardial infarction score (TIMI score) ≥5 scores, high-sensitivity C-reactive protein (hs-CRP) ≥8.44 mg/L, serum creatinine at admission ≥90 μmol/L, heart rate ≥75 times/min and contrast agent dosage/eGFR ≥1.92 between patients with AKI and patients without AKI ( P<0.01 or<0.05). Multivariate Logistic regression analysis result showed that diabetes, LVEF<56%, baseline eGFR< 71.5 ml/(min·1.73 m 2) and hs-CRP ≥8.44 mg/L were the independent risk factors of AKI in patients with AMI ( OR = 2.99, 0.38, 0.30 and 2.48; 95% CI 1.31 to 6.84, 0.16 to 0.88, 0.12 to 0.78 and 1.07 to 5.75; P = 0.010, 0.024, 0.013 and 0.035). The hospital mortality, incidence of adverse cardiovascular events during hospitalization and length of hospital stay in patients with AKI were significantly higher than those in patients without AKI: 11.50% (13/113) vs. 2.39% (28/1 173), 22.12% (25/113) vs. 8.40% (99/1 173) and (12±8) d vs. (10±6) d, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that AKI was the independent risk factors of death and adverse cardiovascular events during hospitalization in patients with AMI ( OR = 5.32 and 3.08, 95% CI 2.67 to 10.59 and 1.89 to 5.03, P<0.01). Conclusions:The incidence of AKI is high in patients with AMI, and previous diabetes history, LVEF<56%, eGFR<71.5 ml/(min·1.73 m 2), hs-CRP≥8.44 mg/L are the independent risk factors of AKI in patients with AMI. The occurrence of AKI after AMI can increase incidence of adverse cardiovascular events during hospitalization and hospital mortality, and prolong the hospital stay.

ABSTRACT

Objective:To design an evaluation scale of perioperative fine management, and test it in hospitals, for verifying its effectiveness and sorting out problems in such management.Methods:November 2020 to August 2021, the scale framework was designed by using the process management theories featuring process-oriented control; then the scale was built based on a risk measurement indicators pool created based on policies, literature, standards and expert interview results on perioperative management; an empirical study was made in the end.Results:The scale consists of 209 risk measurement indicators and Likert 5-level scoring method was adopted to measure the possibility of problems in each respect. A total of 99 experts from 31 hospitals participated in the trial of the scale in 2021, and Cronbach α coefficient was 0.997, indicating good consistency among risk measurement indicators. The median of the average scoring of respective risk measurement indicators was 1.69. The most common problems in the perioperative management process include: lack of analysis and countermeasure research on the perioperative fine management; insufficient medical staff; poor awareness of medical staff in standardized and fine management. Conclusions:This scale can quantitatively evaluate respective aspects of perioperative fine management.

ABSTRACT

Objective:To investigate the status of hypoglycemia fear, diabetes distress, self-regulatory fatigue and self-management in type 2 diabetes patients. The chain mediating effects of self-regulated fatigue and psychological distress on hypoglycemic fear and self-management were investigated.Methods:The Hypoglycemia Fear Survey-Worry Subscale (CHFSII-WS), Diabetes Distress Scale (DDS), Self-Regulatory Fatigue Scale (SRF-S) and Summary of Diabetes Self-Care Activities (SDSCA) were used to investigate the type 2 diabetes patients from the department of Endocrinology of the First Affiliated Hospital in Jinzhou Medical University. And constructed the structural equation model.Results:The scores of fear of hypoglycemia in type 2 diabetes patients were positively correlated with psychological pain and self-regulating fatigue ( r=0.739, 0.625, P<0.05), but negatively correlated with self-management level ( r=-0.602, P<0.05). The psychological pain score was positively correlated with the self-regulating fatigue score ( r=0.669, P<0.05) and negatively correlated with the self-management level score ( r=-0.609, P<0.05). The score of self-regulation fatigue was negatively correlated with the score of self-management ( r=-0.596, P<0.05). Pathway analysis showed that hypoglycemia fear could directly affect self-management behavior, indirectly predict self-management level through self-regulation fatigue and psychological pain respectively, and negatively affect self-management behavior through chain mediation of self-regulation fatigue and psychological pain ( χ2/ df=3.079, GFI=0.920, CFI=0.961, NFI=0.943, IFI=0.961, RMSEA=0.078). Conclusions:The Self-regulated fatigue and psychological distress acts as the chain mediators of hypoglycemic fear and self-management in patients with type 2 diabetes.

ABSTRACT

Objective:To investigate the health status, health-related behaviors and health needs of elderlies in eastern, central and western China and to understand their health experience, for exploring an efficient medical service model, and optimizing allocation of medical resources.Methods:This study used the 2008-2018 database from Chinese longitudinal healthy longevity survey organized by Peking University. It described the concentration trend of medical distance by median, compared the health status, health-related behaviors and health needs of the elderly in eastern, central and western China by χ2 tests, and analyzed time-distribution trends of the poor health status, negative health behaviors and health needs by linear relation test. Results:Among 49 611 subjects included in the study, 7 881 of them self-evaluated their health status as poor, 19 445 evaluated their recent health status as deteriorated, while 14 954 lack routine physical examination, 35 141 lack physical exercise, 8 178 smoked, 7 859 drunk, 35 814 had no access to health education services in their communities, 35 676 expressed their health education needs, and 2 637 lack adequate medical services. The difference of distribution of health status, health-related behaviors and health needs of the elderly in eastern, central and western China was statistically significant ( P<0.05). The health status, negative health behaviors and health needs of the elderly in 2008-2018 presented a linear time distribution trend( P<0.05), while the overall medical distance in eastern, central and western China was 1.02 km, 1.00 km and 1.56 km respectively, and the medical distance in the rural area further than that in the urban areas. Conclusions:The health status of the elderly in China needed to be further improved, the proportion of negative health behaviors was high, and the health needs of the elderly in central and western China were large. Promoting an active medical service mode in central and western China, strengthening the interactions between medical institutions and residential communities will contribute to health needs fulfillment and medical resource utilization.

ABSTRACT

To analyze the prognostic factors of extramedullary relapse (EMR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute lymphoblastic leukemia (ALL).The clinical data of 33 relapsed patients in 95 ALL patients receiving allo-HSCT were analyzed retrospectively. The median time of relapse was 5.7 (0.7-52.3) months. Extramedullary relapse was recorded in 10 cases (10.5%), bone marrow relapse in 15 cases (15.8%), and both extramedullary and marrow relapse were seen in 8 cases (8.4%). The median time of EMR was 7.4(0.7-52.3) months. The most commonly involved organ was central nervous system, followed by testis and bone. The 3-year OS rate in EMR patients was (33.3±11.1) %. Univariate analysis showed that disease state before transplantation ( P=0.026), extramedullary infiltration before transplantation ( P=0.005), conditioning regimens ( P=0.033) and acute graft-versus-host disease(aGVHD) ( P=0.013) were significantly correlated with EMR. Multivariate analysis suggested that extramedullary infiltration ( RR=5.067, 95 %CI1.542-16.645, P=0.007) and aGVHD( RR=3.585, 95 %CI1.245-10.320, P=0.018) were independent predictive factors of EMR in ALL patients after allo-HSCT.

ABSTRACT

Objective To investigate the epidemiological characteristics of acute myocardial infarction (AMI) in Yichang City in the last 5 years, and to provide a basis for targeted prevention and treatment. Methods The annual estimated percentage was used to evaluate the trend of morbidity and mortality of AMI by using the monitoring data from 2015 to 2019 from the health big data platform of Yichang. Results There were 1 976 new cases of AMI in Yichang from 2015 to 2019, with a crude morbidity of 41.96/100 000, and standardized morbidity of 87.52/100 000. Among them the crude incidence rate in males was 57.69/100 000, and 29.84/100 000 in females. The difference was statistically significant (χ2=15.76, P2=45.65, P<0.001). The morbidity and mortality of males and females were increased with age. Conclusion From 2015 to 2019, the morbidity of AMI in Yichang was at a moderately low level in China, but the mortality was higher than the national average. The morbidity showed an upward trend, with men and elderly people aged ≥60 being more serious. Appropriate intervention measures should be taken for different groups of people to reduce the incidence of AMI.

ABSTRACT

Objective:To evaluate risk factors and available treatments of extramedullary relapse (EMR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myeloid leukemia.Methods:A total of 280 patients were retrospectively analyzed from January 2008 to December 2018 in Affiliated Cancer Hospital of Zhengzhou University. Clinical data were collected including disease patterns, pre-transplantation status, chromosome karyotype, conditioning regimen, types of donor, extramedullary disease before transplantation and graft-versus-host disease (GVHD). The log-rank test and Cox proportional hazard model were uesd for univariate analysis and multivariate analysis, respectively.Results:Twenty patients developed EMR (7.14%). The median time of EMR was 7.5 (1-123) months after allo-HSCT. The mortality of EMR was 80% (16/20). Univariate analysis identified disease patterns, second complete remission (CR2) or progressive disease before transplantation, extramedullary disease, abnormal karyotype and conditioning regimen without total body radiation as significant factors correlated to EMR ( P<0.05). Multi-variable analysis revealed that CR2 or progressive disease ( RR=3.468,95% CI 2.189-7.786), abnormal karyotype ( RR=1.494,95% CI 1.020-2.189) and extramedullary disease before transplantation ( RR=8.627,95% CI 3.921-18.452) were independent risk factors of EMR. Conclusions:The clinical outcome of EMR after allo-HSCT is poor.It is crucial to comprehensively assess and identify EMR as early as possible.

ABSTRACT

Objective:To analyze the pathological features of facioscapulohumeral muscular dystrophy (FSHD). For better characterization of inflammatory response in FSHD, we performed histochemical morphological analysis for FSHD and polymyositis (PM) muscle biopsies.In order to provide a reference for guide targeted therapeutic interventions.Methods:The clinical and myopathological data of 30 patients with FSHD from January 2006 to January 2019 in the Sixth Hospital of Shanxi Medical University and the first hospital of Jilin University were retrospectively analyzed. The patients were divided into non-inflammatory infiltration group (16 cases) and inflammatory infiltration group (14 cases) according to the presence or absence of inflammatory cell infiltration. For better characterization of inflammatory response in FSHD, we performed histochemical morphological analysis for two groups of muscles: FSHD and PM muscle biopsies, using Image-Pro plus bioanalytical software.Results:In 30 cases of FSHD, 14 cases showed intramuscular and interstitial inflammatory cell infiltration, especially around the blood vessels. Immunohistochemical staining confirmed that the infiltration of inflammatory cells was mainly CD4 + T lymphocytes. Morphometric analysis showed that there were no significant differences in muscle fiber surface area, density, diameter, inflammatory cell infiltration, regeneration and necrosis between FSHD patients and PM patients ( P>0.05). The total area of myointerstitium in FSHD group was significantly larger than that in PM group ( P=0.03). Conclusions:The pathological morphometric analysis showed that the proliferation of interstitial connective tissue in FSHD inflammatory cell infiltration group was significantly more than that in PM group. Clinicians can identify the two from pathology and provide help for clinical practice.

ABSTRACT

Objective:To investigate the normal range of exhaled nitric oxide (FeNO) in 6-18-year-old children in China, so as to provide a data base for the establishment of FeNO standards for Chinese children.Methods:A multi-center study was conducted on 5 949 children aged 6-18 (3 101 males and 2 848 females) in 16 pro-vinces of 7 administrative districts in China.According to the technical standard recommended by American Thoracic Society/European Respiratory Association, FeNO was measured, and the relationship of FeNO with the sex, age, height, weight, body mass index and region was discussed.Results:The geometric mean FeNO value of Chinese children aged 6-18 was 14.1 ppb, and its 95% confidence interval (skewness distribution) was 1.0-38.2 ppb.The geometric mean FeNO values of children aged 6-11 and 12-18 were 13.1 ppb and 15.7 ppb, respectively, and their 95% confidence intervals (skewness distribution) were 1.0-38.1 ppb and 2.0-38.2 ppb.For children at and under 11 years old, FeNO decreased with age, with a mean decline of 1 ppb per year.The multiple linear regression results suggested that there was a significant correlation between FeNO and age for children aged 6-11, and FeNO of children aged 12-18 was significantly correlated with the gender, height, and region(all P<0.01). Conclusions:FeNO values of Chinese children and adolescents in this study are higher than those obtained by the previous study conducted from 2010 to 2012.For children aged 12-18, 16 ppb is recommended as the clinical cut-off point.For children at or under 11 years old, the influence of age on FeNO should be considered, and the cut-off point of FeNO decreases by 1 ppb as the age is reduced by one year.

ABSTRACT

Objective:To evaluate the clinical effect of Changzhi-Xiaoyuan Decoction auxiliary nasal endoscopic surgery for radioactive sinusitis. Methods:A total of 90 patients with radioactive sinusitis included inour hospital from May 2016 to June 2018 were divided into two group according to the random number table method, 45 in each group. The control group was treated with nasal endoscopic surgery, nasopharyngeal flushing after the surgery andoral clarithromycin. The observation group was treated with Changzhi-Xiaoyuan Decoction on the basis of the control group. Both groups were treated for 2 months, following up for 12 months. Before and after the treatment, for clinical symptom scores, using the modified Lund Mackay Postoperative Endoscopic Score (MLMES) respectively from bilateral maxillary sinus, Ethmoid sinus, frontalsinus, sphenoidsinus, olfactory cleft state of mucous membrane inflammation and mucus secretion and purulent secretion evaluation; tested the cilia transmission rateand clinical efficacy were evaluated. Results:The total effective rate of observation group was 91.1% (41/45), and the control group was 64.4% (29/45). There was statistically significant difference between two groups ( χ2=7.779, P=0.005). After the treatment, stuffy nose, turbinate swelling, nasal secretions, hyposmia, headaches scores of the observation group were significantly lower than those of the control group ( t value were 3.558, 5.582, 5.367, 7.442, 7.115, respectively, all Ps<0.01), the MLMES score was significantly lower than that of the control group ( t=4.762, P<0.01). After the treatment, cilia transmission rate (4.42 ± 0.51 mm/min vs. 3.87 ± 0.38 mm/min, t=5.801) of the observation group was significantly higher than that of the control group ( P<0.01). Conclusions:The Changzhi-Xiaoyuan Decoction combined with auxiliary nasal endoscopic surgery can reduce symptoms of radioactive sinusitis patients with sinus, restore the function of nasal mucosa, and enhance the clinical curative effect.

ABSTRACT

Objective:To conduct data mining on hospital accreditation results for inspirations and clues in hospital management.Methods:The Apriori function contained in the arules package of R software was used to extract the association rules. This practice aimed to analyze association rules of the accreditation results of 56 tertiary hospitals which were made based on tertiary hospital accreditation standard(2011)and Detailed Rules from 2017 to 2019; to explore the correlation between the clauses, and analyze the inspirations for hospital management.Results:A total of 6 566 138 and 247 rules were generated for all clauses and core clauses, receptively. The top 10 rules sorted by lift were selected as strong association rules. Among them, the minimum lift of all clauses and core clauses was 1.41 and 1.53, respectively. There was a strong correlation between the establishment of a quality and safety management team in the hospital and the development & implementation of relevant regulations by the hospital. There were strong correlations among emergency service procedure and regulations, patient rights to know, responsibility system by the first one to receive a complaint, medical safety(adverse)event reporting, development & implementation of antimicrobial management system, as well as training for prevention of multi-drug resistance infection measures, and multi-drug resistance infection hospital infection control system.Conclusions:This study suggested that hospital management should highlight the correlation between regulations development and staffing, that between indicator systems and monitoring feedback systems, and that between indicators in different sectors in the medical process. These correlations can be used as management clues and inspirations for hospital management.
