ABSTRACT
Objective:To analyze the clinical features of convulsion in rotavirus enteritis and the risk factors of multiple convulsion.Methods:The clinical data of children with rotavirus enteritis complicated with convulsion admitted to Xi'an Children's Hospital from January 2018 to March 2021 were retrospectively analyzed. According to whether there was fever during convulsion, they were divided into febrile seizure (FS) group and afebrile seizure (AFS) group.Results:A total of 274 children with rotavirus enteritis accompanied by convulsion were enrolled. The male to female ratio was 2.26∶1 in the FS group, while the male to female ratio was 1∶1.1 in the AFS group. The median number of vomiting in the AFS group was higher than that in the FS group: 4(2, 6) times per day vs. 2(1, 5) times per day, P<0.01. One convulsion was dominant in the FS group (80.68%), and more than two convulsions in the AFS group (62.90%). In the FS group, 60.23% of convulsions occurred on the first day of the course of disease, while in the AFS group,79.57% of convulsions mainly occurred on the second and third day of the course of disease. There was no statistical difference in duration of convulsion and overall course of disease between the two groups ( P>0.05). The median of hypersensitive C-reactive protein (CRP) and procalcitonin (PCT) in FS group were higher than those in AFS group: 5.52(1.45, 15.50) mg/L vs. 0.98(0.50, 3.17) mg/L, 0.17(0.07, 0.46) μg/L vs. 0.06(0.05, 0.15) μg/L. The median of alanine aminotransferase (ALT), aspartate aminotransferase (AST), uric acid (UA) and creatine kinase isoenzyme(CK-MB) in the AFS group were higher than those in the FS group: 28.00(21.00, 34.25) U/L vs. 25.00(19.00, 31.00) U/L, 53.00(45.00, 62.00) U/L vs. 50.00(40.00, 58.00) U/L, 390.00(296.00, 474.25) μmol/L vs. 331.00(250.00, 399.75) μmol/L, 67.00(49.75, 94.25) U/L vs. 59.50(37.25, 78.75) U/L, the differences were statistically significant ( P<0.05). The median age and the median of UA levels in ≥3 convulsions group were higher than those in ≤2 convulsions group: 21(18, 26) months vs. 18(15, 21) months, 411.00(296.50, 496.50) μmol/L vs. 364.00(278.00, 440.50) μmol/L, while the median of serum Na +, the mean value of serum Cl - in the ≥3 convulsions group were lower than those in the ≤2 convulsions group: 135.50(133.75, 137.25) mmol/L vs. 136.60(134.50, 138.20) mmol/L, (103.76 ± 3.26) mmol/L vs. (105.08 ± 4.26) mmol/L, the differences were statistically significant ( P<0.05). The age ≥18 months in children with rotavirus enteritis and convulsion ( OR = 3.359, P = 0.002, 95% CI 1.544 - 7.307) and the serum Cl - < 104.8 mmol/L ( OR = 2.17, P = 0.019, 95% CI 1.138 - 4.138) had an increased risk of convulsions ≥3 times during the course of rotavirus enteritis. Conclusions:Rotavirus enteritis FS mostly occurred on the first day of the course of disease, most of them had convulsion once, hs-CRP and PCT were relatively high. In AFS, convulsions were more than 2 times, and occurred on the 2nd and 3rd day of the course of disease. ALT, AST and UA were relatively high. Children with age ≥18 months and serum Cl - < 104.8 mmol/L had an increased risk of convulsions ≥3 times during the course of the disease.
ABSTRACT
Objective:To understand the epidemiological and clinical characteristics of children with severe and critical hemorrhagic fever with renal syndrome(HFRS), and to accumulate experience in the diagnosis and treatment of severe and critical HFRS in children.Methods:A retrospective analysis method was used to collect the clinical data of 49 children diagnosed with HFRS, who were admitted to the Department of Infectious Diseases, Children′s Hospital Affiliated to Xi′an Jiaotong University from January 2019 to December 2021 and classified as severe or critical group.The epidemiological data, characteristics, clinical manifestations, laboratory examinations, diagnosis and treatment outcomes of the children were analyzed.Results:Among the 49 children with severe HFRS, the ratio of male∶female was 3.45∶1(38∶11), the median age was 10 years and 8 months old, and the highest proportion was 6-12 years old.The peak incidence was in November and December(75.51%).Most of them lived in rural areas, with a total of 39 cases(79.59%).All patients had fever onset, gastrointestinal symptoms(vomiting, abdominal pain, diarrhea, 81.63%)and hyperemia of skin and mucous membranes(77.55%)were common, but typical headache, backache pain and orbital pain(three pains)only accounted for 15 cases(30.6%).Laboratory test results: the white blood cells in routine blood increased in 42 cases(85.71%), while the platelets decreased in 47 cases(95.91%).The procalcitonin was increased in 48 cases(97.95%).The alanine aminotransferase was elevated in 49 cases(100%), while the albumin of 38 cases(77.55%)were lower than 30 g/L.The urea nitrogen increased in 34 cases(69.38%), and the creatinine increased in 47 cases(95.91%).The creatine kinase isozyme was elevated in 41 cases(83.67%).Forty-nine children had different degrees of electrolyte imbalance, among which low sodium(91.83%)and low calcium(85.71%)were the most common.The urine protein was positive in 47 cases(95.91%), and the urine red blood cell was positive in 38 cases(77.55%).Ultrasonography of the urinary system revealed abnormalities in the kidneys and surrounding kidneys in 43 cases(91.48%).Twenty-eight(58.33%)patients had abnormal electrocardiogram.All the 49 patients were clinically cured.Conclusion:Severe HFRS is mainly in rural male children aged 6-12 years, mainly with fever and gastrointestinal symptoms, lack of typical three pain symptoms.When white blood cell count and procalcitonin significantly increased, platelet count significantly decreased, liver and kidney function impaired and electrolyte imbalance, severe cases should be highly suspected.Early identification of critically ill children and active treatment are critical to their prognosis.
ABSTRACT
Background@#and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. @*Methods@#This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. @*Results@#Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; P=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; P=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). @*Conclusion@#In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.
ABSTRACT
Objective:To explore the etiological diagnostic value of metagenomic next-generation sequencing (mNGS) in peritoneal dialysis (PD)-related peritonitis.Methods:The study was a retrospective cohort study. The clinical data of patients with PD-related peritonitis who were treated and underwent microbial cultivation and mNGS test at the same time from June 2020 to July 2021 in the Affiliated Drum Tower Hospital, Medical School of Nanjing University were analyzed. The positive rate, detection time and consistency between mNGS test and traditional microbial culture were compared.Results:A total of 18 patients with age of (50.4±15.4) years old and median dialysis time of 34.0 (12.4, 62.0) months were enrolled in the study, including 11 males and 7 females. Pathogenic microorganisms were isolated in 17 patients by mNGS test, with a positive rate of 17/18, which was higher than 13/18 of microbial culture, but the difference was not statistically significant ( P=0.219). Both mNGS test and microbial culture isolated positive pathogenic bacteria in 12 patients, and mNGS test isolated the same types of pathogenic bacteria as microbial cultivation did in 11 patients. In five patients with negative microbial culture, mNGS test also isolated pathogenic microorganisms, including 3 cases of Staphylococcus epidermidis, 1 case of Mycobacterium tuberculosis and 1 case of Ureaplasma urealyticum. In 1 patient, microbial culture isolated pathogenic bacteria ( Escherichia coli) whereas mNGS test did not. The detection time of mNGS was 25.0 (24.0, 27.0) h, which was significantly shorter than 89.0 (72.8, 122.0) h of microbial culture ( Z=3.726, P<0.001). Conclusions:mNGS test can improve the detection rate of pathogenic microorganisms in PD-related peritonitis and greatly shorten the detection time, and has good consistency with microbial culture. mNGS may provide a new approach for pathogen identification of PD-related peritonitis, especially refractory peritonitis.
ABSTRACT
Objective:To summarize the clinical characteristics, causes of misdiagnosis and preventive measures of infectious mononucleosis (IM) in children, and to improve the ability of clinicians in early diagnosis of IM in children.Methods:The clinical data of 468 children with IM in Xi′an Children′s Hospital from January 2018 to December 2021 were retrospectively analyzed, including general situation, disease onset, diagnosis and misdiagnosis.Results:Among the 468 children, 33 cases were clinically diagnosed and 435 cases were a definitely diagnosed; 281 males (60.04%) and 187 females (39.96%); the incidence rate was highest in preschool children (43.80%, 205/468) and in autumn (33.12%, 155/468). The first symptoms were fever (52.99%, 248/468), eyelid edema (15.38%,72/468) and neck mass (14.96%, 70/468). The fever rate was 90.38% (423/468), and the median time of first fever appearance was on the first (first, second) day of disease course, and the median duration of fever was 6 (4, 8) d. The median time of first visit was on the third (first, fifth) day of disease course, and the time of diagnosis was on the seventh (fifth, ninth) day of disease course. Blood routine examination showed that the proportion of white blood cell count increased was 51.92% (243/468), the proportion of lymphocytes increased was 61.75% (289/468), and the proportion of abnormal lymphocytes increased (≥10%) in peripheral blood was 58.97% (276/468). The lymphocyte subsets of 364 children were detected, the rate of helper T lymphocytes (Th cells) decreased was 80.22% (292/364), the rate of suppressor T lymphocytes (Ts cells) increased was 99.45% (362/364), the value and decreased rate of Th cells/Ts cells were 0.24 (0.16, 0.40) and 100.00% (364/364), rate of B lymphocytes decreased was 93.96% (342/364), rates of natural killer cells decreased and increased were 35.16% (128/364) and 0.55% (2/364). The misdiagnosis rate was 55.13% (258/468), and the misdiagnosis time was on the fifth (fourth, seventh) day of disease course. Among the 258 misdiagnosed children, 105 cases (40.70%) were misdiagnosed as upper respiratory tract infection, 65 cases (25.19%) as acute suppurative tonsillitis, 27 cases (10.47%) as acute cervical lymphadenitis or neck mass.Conclusions:Due to the complex and diverse clinical manifestations of IM in children, it is easy to be misdiagnosed in the early stage of the disease. So, it is necessary for clinicians to master the clinical characteristics of IM in children, constantly improve the level of diagnosis and treatment, and reduce the misdiagnosis rate.
ABSTRACT
Objective:To investigate the association of single nucleotide polymorphisms(SNPs)in the vitamin D receptor(VDR)gene with influenza susceptibility and severity of disease in children.Methods:Peripheral venous blood was collected from 172 children with influenza A (study group) and 88 healthy children (healthy control group) admitted to Xi ′an Children′s Hospital and Xi ′an Central Hospital from February 2019 to February 2021.Serum 25-hydroxyvitamin D(25-OH-D) level was detected by using 25-OH-D kit.The study group was divided into three groups according to clinical syndrome: mild group, severe group, and critical group.Four candidate loci in the VDR gene(ApaI, TaqI, FokI, and BSMI)were selected, and polymorphisms in the VDR gene of each group were determined by polymerase chain reaction restriction fragment length polymorphism and analyzed in relation to children with influenza.Results:Compared with the healthy control group[(109.65±4.35) nmol/L], the serum 25-OH-D levels in the study groups were lower[(73.55±2.46)nmol/L in the mild group, (45.59±4.62) nmol/L in the severe group, and (33.65±3.87) nmol/L in the critical group]( P<0.05); Genotypes AA, Aa and allele A of the ApaI locus(51.74%, 22.67%, and 63.08%, respectively)and genotypes FF, Ff and allele F of the FokI locus(41.86%, 34.88%, and 59.30%, respectively)accounted for a significantly higher proportion of cases in the study group than those in healthy control group(11.36%, 14.77%, 18.75%, 10.23%, 13.64%, and 17.05%, respectively)( P<0.05). The proportion of allele A at the ApaI locus and genotypes AA and Aa in severe group(63.70%, 43.84%, and 28.76%) were significantly higher than those in mild group(47.37%, 35.09%, and 24.56%)( P<0.05); The proportion of allele A and genotype AA and at the ApaI locus in critical group(92.86%, 88.10%, and 49.52%) were significantly higher than those in severe group( P<0.05). Serum 25-OH-D<50 nmol/L( OR=5.087, 95% CI 3.114-5.648), ApaI site genotypes AA ( OR=4.011, 95% CI 1.217-18.624)and Aa( OR=3.839, 95% CI 2.483-1.456), FokI site genotypes FF( OR=4.112, 95% CI 3.215-20.775)and Ff( OR=4.591, 95% CI 0.032-10.936)were risk factors for the onset of influenza in children. Conclusion:Serum 25-OH-D deficiency is associated with childhood influenza, and VDR gene genotype AA and Aa of ApaI locus, and FokI site genotype FF, Ff may increase the risk of childhood influenza susceptibility, and allele A of ApaI locus and genotypes AA and Aa are associated with the severity of influenza.
ABSTRACT
Insomnia has become a common central nervous system disease. At present, the pathogenesis of insomnia is not clear. Animal models can help us understand the pathogenesis of the disease and can be used in transformational medicine. Therefore, it is very necessary to establish an appropriate model of insomnia. Clinical data show that insomnia patients with high levels of thyroxine and often accompanied by cardiovascular problems, a common mechanism underlying all of these physiological disruptions is the sympathetic nervous system. Combined with the characteristics of chronic onset of clinical insomnia, an insomnia model induced by long-term intraperitoneal injection of thyroid hormone has been created in our laboratory. In this paper, the insomnia-like state of the model was evaluated based on three validity criteria. Face validity has been demonstrated in metabolism, the Morris water maze, electrocardiogram (ECG) and electroencephalogram (EEG). Structure validity has been proved by the results of targeted metabolomics. After treatment with diazepam, a commonly used clinical anti-insomnia drug, the above physiological and pathological disorders were reversed. The results of comprehensive analysis show that the established thyrotoxicosis-associated insomnia model meets the validity requirement to establish an appropriate animal model of insomnia. The model presented in this article might help to study pathogenetic mechanisms of clinical insomnia, as well as to test promising methods of insomnia treatment.
ABSTRACT
Objective:To assess the prognostic value of modified Charlson comorbidity index (mCCI) combined with serum albumin for long-term prognosis in peritoneal dialysis (PD) patients.Methods:From January 1, 2007 to June 30, 2015, patients who started PD in Nanjing Drum Tower Hospital were enrolled in this retrospective cohort study. Clinical data including gender, age, underlying diseases, laboratory examination and prognosis were collected. The mCCI at the beginning of PD was calculated. Whether the duration of PD exceeded 5 years was used as an indicator to evaluate the prognosis. The patients were divided into≥5 years group and<5 years group according to the duration of PD, and the data were compared between the two groups. Cox regression model was constructed to analyze the influencing factors of all-cause death in PD patients. Multivariate logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the predictive value of mCCI and serum albumin levels on whether patients could maintain long-term PD.Results:Of the 183 patients included [males 106(57.9%), females 77(42.1%); (53.35±16.50) years old; 162 cases (88.5%) with hypertension, 55 cases (30.1%) with diabetes], 97 cases had PD duration for ≥5 years and 86 cases less than 5 years. The overall 5-year technical survival rate was 65.1%. At the beginning of PD, compared with the dialysis age≥5 years group, the patients in the dialysis age less than 5 years group had older age, higher mCCI, lower serum albumin level, and higher C-reactive protein (CRP) level (all P<0.05), but there were no significant differences in gender, education level, electrolyte, mean arterial pressure, high densitv lipoprotein (HDL), low-density lipoprotein (LDL) and PD adequacy index between the two groups (all P>0.05). Multivariate logistic regression analysis showed that increased age ( OR=1.022, 95% CI 1.000-1.043, P=0.046), increased mCCI ( OR=1.620, 95% CI 1.300-2.018, P<0.001) and decreased serum albumin ( OR=0.807, 95% CI 0.730-0.893, P<0.001) were independent predictors for the duration of PD<5 years. ROC curve analysis showed that the area under ROC curves ( AUC) of mCCI, serum albumin level and combined prediction probability of the two for the duration of PD<5 years were 0.647(95% CI 0.568-0.727), 0.655(95% CI 0.577-0.734), and 0.767(95% CI 0.700-0.835), respectively, indicating that the accuracy of combined parameters to predict survival outcome was higher than that of any single parameter. Multivariate Cox analysis showed that increased age ( HR=1.073, 95% CI 1.046-1.100, P<0.001), increased mCCI ( HR=1.198, 95% CI 1.044-1.375, P=0.010) and decreased serum albumin ( HR=0.904, 95% CI 0.843-0.969, P=0.004) were independent influencing factors for all-cause death in PD patients. Conclusions:Old age, high mCCI and low serum albumin level are influencing factors for dialysis age<5 years and all-cause death in PD patients. mCCI combined with serum albumin level can improve the accuracy of predicting the long-term dialysis in PD patients.
ABSTRACT
Objective:To study the relationship between the level of high mobility group protein 1(HMGB1)and the severity of hand, foot and mouth disease (HFMD).Methods:A total of 150 children with enterovirus 71(EV71) HFMD admitted to Xi′an Children′s Hospital from April 2018 to December 2019 were selected as the study objects, including 100 mild cases(normal group) and 50 severe cases(severe group). Meanwhile, 50 healthy children during the same period were selected as control group.The level of HMGB1 in plasma was detected by ELISA.The clinical data and laboratory examination of the case group were collected.The factors that may affect the conversion of HFMD to severe were analyzed by single factor and multi-factor Logistic regression analysis.The risk factors of conversion of HFMD to severe and the correlation between the level of HMGB1 in plasma and the severity of HFMD were discussed.Results:The level of HMGB1 in EV71 HFMD children in the acute stage[(13 700±3 036)pg/mL] was significantly higher than that in the control group[(10 116±2 435) pg/mL]( t=5.913, P<0.05). After treatment, the level of HMGB1 decreased in the convalescence period[(10 658±2 349) pg/mL], and the difference was not statistically significant compared with the control group ( t=2.515, P>0.05). Blood glucose, white blood cell count and HMGB1 level in the severe group were all higher than those in the normal group (all P<0.05). Multivariate Logistic regression analysis found that the levels of blood glucose >8.3 mmol/L, peripheral blood leukocyte >15×10 9/L, and HMGB1≥ 13 110 pg/mL were the risk factors for severe aggravation of HFMD in children.The receiver operating characteristic curve analysis showed that when HMGB1 was 13 110 pg/mL, the Yoden index was the highest, with a sensitivity of 81.6% and a specificity of 72.0%. Conclusion:WBC>15×10 9/L, blood glucose>8.3 mmol/L and HMGB1≥13 110 pg/mL are the risk factors of HFMD.When HMGB1 is higher than, it suggests that HFMD may develop to severe.
ABSTRACT
Objective:In this study, the clinical data of biliary atresia(BA) and infant intrahepatic cholestasis(IHC) was reviewed, and the utility of gamma-glutamyl transpeptidase(GGT) and liver Young′s modulus in the differential diagnosis of BA and IHC in infants was discussed.Methods:Based on the clinical data of 120 infants with cholestasis treated in the Children′s Hospital Affiliated to Xi′an Jiaotong University, from September 2017 to December 2019, the infants were divided into two groups according to the results of intraoperative cholangiography and follow-up: BA group( n=50); IHC group( n=70). The age, clinical manifestations, laboratory examination results, gallbladder contraction rate, hepatobiliary scintigraphy, liver Young′s modulus, and medical treatment effects were compared between the two groups.The utility of GGT and liver Young′s modulus in the differential diagnosis of BA and IHC was analyzed. Results:The age, alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bile acid, fasting blood glucose, blood ammonia and splenomegaly between the two groups were compared and the results showed no statistical significance( P>0.05). In contrast, there were statistically significant differences( P<0.001) in stool color, liver size, total bilirubin(TB), direct bilirubin(DB), GGT, liver Young′s modulus, positive hepatobiliary scintigraphy, gallbladder contraction rate at 1 hour after meal, and medical treatment effect between the two groups.TB, DB, GGT, liver Young′s modulus and GGT combined with liver Young′s modulus were analyzed using ROC curves, and the area under the curve(AUC) were 0.820, 0.809, 0.906, 0.876 and 0.926, respectively.When GGT exceeded the cut-off value of 198.85 U/L, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of BA were 82.0%, 84.3%, 78.8%, 86.8% and 83.3%, respectively.When liver Young′s modulus exceeded the cut-off value of 8.6 kPa, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of BA were 88.0%, 80.0%, 75.9%, 90.3% and 83.3%, respectively.The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of GGT combined with liver Young′s modulus in diagnosing BA were 98.0%, 68.6%, 69.0%, 98.0% and 80.8%, respectively.Multivariate logistic regression analysis found that DB>115.55 μmol/L, GGT>198.85 U/L, and liver Young′s modulus>8.6 kPa were risk factors for BA( OR=9.510, P=0.001; OR=24.634, P<0.001; OR=21.469, P<0.001). Conclusion:GGT and liver Young′s modulus are useful in the differential diagnosis of BA and IHC.If GGT and liver Young′s modulu sexceed the threshold values of 198.85 U/L and 8.6 kPa respectively, it can effectively indicate that the child is BA.
ABSTRACT
Objective:To investigate the difference of radiofrequency ablation combined with ethanol ablation and radiofrequency ablation in the treatment of benign cystic solid thyroid nodule.Methods:A total of 80 patients who visited the Thyroid Surgery Department of the First Affiliated Hospital of Zhengzhou University from January 2015 to July 2018 were selected. All selected patients are required to meet the following criteria: (1)Color doppler ultrasonography of the neck revealed a cystic solid thyroid nodule greater than 20 mm in diameter. (2) The results of fine needle aspiration cytology of thyroid nodules were benign. (3)The patients is to undergo radiofrequency ablation of thyroid nodule. According to the condition and patients′ wishes, radiofrequency ablation (Group A, n=40) and combined ethanol and radiofrequency ablation(Group B, n=40) were performed respectively to observe the changes of nodule volume and maximum diameter at 3, 6 and 12 months after surgery.The difference of intraoperative radiofrequency ablation energy, postoperative complications and patient satisfaction at 12 months after operation were also observed. The respective clinical effects of the two groups and the difference of curative effects between the two groups were analyzed. Two-factor repeated measurement analysis of variance or independent sample t test was used to compare the measurement data in line with normal distribution between groups. Friedman′s rank sum test was used for comparison of measurement data groups that did not conform to normal distribution, and Bonferroni correction was used for pairwise comparison. Chi-square test was used to compare the counting data between groups. Results:On the 12th months after operation, the volume reduction of of nodules in group B was greater than that of group A, and the difference was statistically significant[(7.0±5.1) mL vs (5.5±4.9) mL, P<0.05]. The maximum diameter reduction of nodules in group B was greater than that of group A and the difference was statistically significant [(1.5±0.6) cm vs (1.4±0.8) cm, P<0.05]. During the period of 6 to 12 months after operation, the trend of nodular shrinkage in group B was more obvious than that in group A ( P<0.05). The radiofrequency ablation energy of group was lower than that of group A, and the difference was statistically significant [(2.37±1.18) kJ vs (3.89±1.17) kJ, P<0.05]. Voice reduction occurred in 2 cases and recovered within 2 weeks.Local bleeding occurred in 1 case during the operation, which was stopped after ablation. There was no statistical significance in the satisfaction of patients in group A and group B (87.5% vs 90%, P>0.05). Conclusion:Compared with radiofrequency ablation, radiofrequency ablation combined with ethanol ablation for benign cystic solid thyroid nodules can achieve better nodule reduction effect and reduce the ablation energy.
ABSTRACT
Objective:To investigate the clinical value of plasma brain natriuretic peptide (BNP) levels in predicting the severity of hand, foot and mouth disease (HFMD) in children with coxsackie virus A6 (CV-A6) infection.Methods:A total of 305 children with CV-A6 type HFMD admitted to Xi′an Children′s Hospital from January 2017 to December 2018 were divided into general group (200 cases) and severe group (105 cases) according to the severity of the disease.The receiver operating characteristic curve was used to calculate the value of plasma BNP levels to predict the severe CV-A6 HFMD.Multivariate logistic regression analysis was used to analyze the correlation between the related factors and the severity of CV-A6 HFMD.Results:Compared with the normal group, children in the severe group had statistically significant differences in WBC level, BNP level, neurological symptoms, circulatory disorders, and blood glucose levels(all P<0.05). The optimal cut-off value of the receiver operating characteristic curve for BNP level to predict severe HFMD was 294.85 ng/L.Multivariate logistic regression analysis found that WBC>15×10 9/L, blood glucose> 8.3 mmol/L, and BNP>294.85 ng/L were related to the severity of CV-A6 HFMD( OR=2.275, P=0.013; OR=6.057, P=0.028; OR=1.008, P<0.001). Conclusion:BNP>294.85 ng/L is closely related to the severity of CV-A6 HFMD and has predictive value.It is an early warning factor for the severity of CV-A6 HFMD.
ABSTRACT
Objective:To explore the application effect of dysphagia rehabilitation pathway nursing in patients with dysphagia after stroke.Methods:Eighty patients with dysphagia after stroke who were admitted to the hospital from October 2019 to April 2020 were enrolled as the research objects. They were divided into observation group and control group by random number table method, 40 cases in each group. The control group was given routine nursing intervention, while observation group was given dysphagia rehabilitation pathway nursing on basis of control group. The swallowing function, serum ALBumin (ALB), subcutaneous fat, weight, incidence of aspiration pneumonia and nutrition deficiency were compared between the two groups at admission, after 2 weeks and 4 weeks of intervention.Results:After 2 weeks of intervention, the number of cases with normal swallowing function in observation group was significantly more than that in control group (15, 30 vs 7, 21) ( χ2 value was 4.013, 4.381, P<0.05). After 4 weeks of intervention, number of cases with abnormal swallowing function in observation group was less than that in control group (2 vs 9) ( χ2 value was 5.165, P<0.05). After 4 weeks of intervention, level of plasma ALB and TSF, and weight in the observation group were significantly higher than those in the control group [(39.46±2.84)g/L, (19.28±2.20)mm, (19.28±2.20) kg vs (31.71±2.59)g/L, (17.06±2.35)mm, (62.48±4.29)kg]( t value was 12.752, 4.362, 2.317, P<0.05), while incidence rates of aspiration pneumonia and nutrition deficiency were significantly lower than those in control group [12.50% (5/40), 2.50% (1/40) vs 32.50% (13/40), 32.50% (13/40)] ( χ2 value was 4.588, 12.468, P<0.05). Conclusion:Application of dysphagia rehabilitation pathway nursing in patients with dysphagia after stroke can significantly promote the recovery of swallowing function, improve their nutrition status, and reduce incidence of aspiration pneumonia and nutrition deficiency.
ABSTRACT
Objective:To explore the relationship of Vitamin A and Vitamin D with the incidence and severity of hand, foot and mouth disease(HFMD) as well as with the anti-viral immune index interferon-α(INF-α), and to investigate the role of Vitamin A and Vitamin D in HFMD.Methods:A total of 305 children with Coxsackie virus A6(CA6) HFMD admitted at Xi′an Children′s Hospital from January 2017 to December 2018 were enrolled in the study.One hundred healthy children whose gender and age matched with those of children in the case group were selected as the healthy control group.Serum Vitamin A levels were detected by high performance liquid chromatography.Enzyme-linked immunosorbent assay was used to detect the levels of Vitamin D and IFN-α, and the correlation of the levels of Vitamin A and Vitamin D with the severity of HFMD was analyzed.Results:The levels of serum Vitamin A[(0.96±0.39) mg/mol] and Vitamin D [(42.14±15.13) μg/L] in patients with CA6 HFMD were lower than those of the healthy control group[(1.26±0.29) mg/mol, (49.63±8.86) μg/L], and the differences were statistically significant(all P<0.05). Logistic multivariate regression analysis showed that WBC>15×10 9/L, blood sugar>8.3 mmol/L, the deficiency of Vitamin A level and Vitamin D level were all risk factors for severe CA6 HFMD in children( OR=2.303, 4.622, 7.346, 5.211; all P<0.05). According to the receiver operating characteristic curve analysis, the Youden index was the largest at a Vitamin A level of 0.725 mg/mol, and the corresponding sensitivity and specificity were 82.0% and 64.8%, respectively.When Vitamin D level was 32.88 μg/L, the Youden index was the highest, and the sensitivity and specificity were 84.5% and 61.9%, respectively.The serum IFN-α concentration of patients with CA6 HFMD [(84.44±26.28) ng/L] was higher than that of the healthy control group [(36.58±14.39) ng/L], and the difference was statistically significant( P<0.05). In addition, the serum IFN-α concentration in severe HFMD children [(71.48±18.34) ng/L] was significantly lower than that in the common HFMD children [(91.25±27.27) ng/L], and the difference was statistically significant( P<0.05). The results of correlation analysis showed that serum IFN-α concentration is positively correlated with Vitamin A and Vitamin D levels ( r=0.783, 0.239; all P<0.001). Conclusions:The levels of serum Vitamin A and Vitamin D decreased in children with HFMD.WBC>15×10 9/L, blood sugar>8.3 mmol/L, the deficiency of Vitamin A level and Vitamin D level are related to severe HFMD.The se-rum IFN-α concentration is positively correlated with the levels of Vitamin A and Vitamin D. The deficiency of Vitamin A and Vitamin D is one of the early warning factors of severe HFMD.
ABSTRACT
Objective@#To investigate the clinical value of plasma brain natriuretic peptide (BNP) levels in predicting the severity of hand, foot and mouth disease (HFMD) in children with coxsackie virus A6 (CV-A6) infection.@*Methods@#A total of 305 children with CV-A6 type HFMD admitted to Xi′an Children′s Hospital from January 2017 to December 2018 were divided into general group (200 cases) and severe group (105 cases) according to the severity of the disease.The receiver operating characteristic curve was used to calculate the value of plasma BNP levels to predict the severe CV-A6 HFMD.Multivariate logistic regression analysis was used to analyze the correlation between the related factors and the severity of CV-A6 HFMD.@*Results@#Compared with the normal group, children in the severe group had statistically significant differences in WBC level, BNP level, neurological symptoms, circulatory disorders, and blood glucose levels(all P<0.05). The optimal cut-off value of the receiver operating characteristic curve for BNP level to predict severe HFMD was 294.85 ng/L.Multivariate logistic regression analysis found that WBC>15×109/L, blood glucose> 8.3 mmol/L, and BNP>294.85 ng/L were related to the severity of CV-A6 HFMD(OR=2.275, P=0.013; OR=6.057, P=0.028; OR=1.008, P<0.001).@*Conclusion@#BNP>294.85 ng/L is closely related to the severity of CV-A6 HFMD and has predictive value.It is an early warning factor for the severity of CV-A6 HFMD.

Among 95 patients, the ratio of male to female was 1.1∶1.0; the peak period of incidence of HFMD was from May to July, and the main age of onset of severe HFMD was under 3 years old.The main clinical manifestations were mental retardation, vomiting, irritability, lethargy and convulsion.Severe cases of CA6 are prone to convulsion.The main form of rash in CA6 cases was bullous rash, and demethylation may occur in recovery period.The rash in EV71 cases was small, thick, hard and few.After active treatment, only one child with EV71 infection died because of severe cerebral dysfunction, frequent convulsions and neurogenic pulmonary edema.The other child was discharged with hemiplegia and language dysfunction.The other severe children were cured and discharged from hospital.@*Conclusions@#In 2018, CA6 was the main pathogen of severe HFMD in Xi′an, with bullae was the main manifestation of skin rash, and nail removal could occur during convalescence.Critical and death cases were still caused by EV71.
ABSTRACT
Objective To explore the expression changes of SIRT1 and related inflammatory regula-tors in peripheral blood of patients with major depressive disorder and analyze the correlation between SIRT1, depression and inflammatory regulators. Methods Forty patients with major depressive disorder and forty healthy controls were selected. Hamilton Depression Scale (HAMD-17) was used to assess the degree of de- pression in patients with depressive disorder. Quantitative Real-time PCR( RT-PCR) was used to detect the relative expression levels of SIRT1,Elf-1,NF-κB,IL-1β,GM-CSF mRNA,and enzyme linked immunosorbent assay(ELISA) was used to detect the expression levels of SIRT1,Elf-1,NF-κB,IL-1β,GM-CSF proteins. The correlation between the severity of depression disorder and SIRT1 and the correlation between SIRT1 and Elf-1 and NF-κB were analyzed. Results (1)Compared with the control group,SIRT1 mRNA expression significantly decreased in the case group (P<0. 01),while Elf-1,NF-κB,IL-1β,GM-CSF mRNA expression significantly increased in the case group (P<0. 01). ( 2) The expression of plasma SIRT1 protein((8. 23± 1. 78)ng/ml) in the case group was lower than that in the control group (P<0. 01). The expressions of plas-ma Elf-1 protein((1 921. 67±271. 07)pg/ml),NF-κB protein((2 057. 29±260. 44)pg/ml),IL-1β protein ((186. 60±31. 00) pg/ml) and GM-CSF protein((183. 69±28. 87) pg/ml) were higher than those in the control group((1 512. 92±284. 54)pg/ml,(1537. 18±313. 82) pg/ml,(144. 79±31. 48) pg/ml,(162. 82± 27. 90) pg/ml,respectively,all P<0. 01). (3) SIRT1 mRNA expression level was negatively correlated with the severity of major depressive disorder (r=-0. 51, P<0. 01) and was negatively correlated with the mRNA expression levels of Elf-1 and NF-κB (r=-0. 66,P<0. 01,r=-0. 64,P<0. 01). Conclusion The expres-sion level of SIRT1 in peripheral blood of patients with major depressive disorder is correlated with the sever-ity of depression. This may be related to the decrease of SIRT1 expression in peripheral blood leukocytes of patients with major depressive disorder,which activates the pathway of NF-κB and Elf-1 and increase expres-sion of GM-CSF and IL-1β.
ABSTRACT
OBJECTIVE@#To investigate the effect of the chemoprotectant tempol on the anti-tumor activity of cisplatin (DDP).@*METHODS@#The cellular toxicity of tempol in human colon cancer SW480 cells and mouse colon cancer CT26 cells were evaluated using MTT and cell counting kit-8 assays. CalcuSyn software analysis was used to determine the interaction between tempol and DDP in inhibition of the cell viability. A subcutaneous homograft mouse model of colon cancer was established. The mice were randomly divided into control group, tempol group, cisplatin group and tempol + DDP treatment group with intraperitoneal injections of the indicated agents. The tumor size, body weight and lifespan of the mice were measured, and HE staining was used to analyze the cytotoxic effect of the agents on the kidney and liver. Immunohistochemistry and Western blotting were performed to detect the expression of Bax and Bcl2 in the tumor tissue, and TUNEL staining was used to analyze the tumor cell apoptosis. The level of reactive oxygen species (ROS) in the tumor tissue was determined using flow cytometry.@*RESULTS@#Tempol showed inhibitory effects on the viability of SW480 and CT26 cells. CalcuSyn software analysis showed that tempol had a synergistic anti-tumor effect with DDP (CI < 1). In the homograft mouse model, tempol treatment alone did not produce obvious anti-tumor effect. HE staining showed that the combined use of tempol and DDP alleviated DDP-induced fibrogenesis in the kidneys, but tempol also reduced the anti-tumor activity of DDP. Compared with the mice treated with DDP alone, the mice treated with both tempol and DDP had a significantly larger tumor size ( < 0.01) and a shorter lifespan ( < 0.05). Tempol significantly reversed DDP-induced expression of Bax and Bcl2 in the tumor tissue and tumor cell apoptosis ( < 0.001), and obviously reduced the elevation of ROS level in the tumor tissue induced by DDP treatment ( < 0.05).@*CONCLUSIONS@#Tempol can attenuate the anti-tumor effect of DDP while reducing the side effects of DDP. Caution must be taken and the risks and benefits should be carefully weighed when considering the use of tempol as an anti-oxidant to reduce the toxicities of DDP.
