ABSTRACT
Objective:To investigate the change of left atrial volume and function in patients with hypertensive disorders of pregnancy (HDPs) by four-dimensional automatic left atrial quantitative analysis (4D LAQ) and analyze the predictive value of risk stratification.Methods:A total of 60 patients diagnosed with hypertensive disorder of pregnancy in Henan Provincial People′s Hospital from March to December 2021 were randomly enrolled, which were divided into gestational hypertension group (low risk group, n=30) and preeclampsia group (medium and high risk group, n=30) according to the disease development and risk stratification method reported in the literature; another 30 healthy pregnant women matched for age, gestational weeks and body mass index were selected as the control group. Left atrial anteroposterior diameter (LAd), interventricular septum thickness (IVSd), left ventricular end diastolic diameter (LVd), left ventricular ejection fraction (LVEF), left ventricular myocardial mass index (LVMI), peak early diastolic (E) and late diastolic (A) velocities of mitral inflow, and e′ values on the septal and lateral mitral annulus sides were routinely measured to calculate E/A and E/e′ values. Left atrial volume and strain parameters were obtained using 4D LAQ technique, including left atrial minimum volume (LAVmin), left atrial maximum volume (LAVmax), left atrial presystolic volume (LAVpreA), left atrial maximum volume index (LAVImax), left atrial inflation index (LAEI), left atrial stroke volume (LAEV), left atrial fraction (LAEF), longitudinal strain of left atrial reserve, conduit and systolic period (LASr, LAScd, LASct), circumferential strain of left atrial reserve, conduit and systolic period(LASr-c, LAScd-c, LASct-c). The differences among the three groups were compared. Multiple Logistics regression analysis was used to obtain the relevant indicators of risk stratification of HDPs and ROC curves were used for assessment. Results:Compared with the control group, E/e′, LAVmin, LAVpreA, LAScd, and LAScd-c increased, and LAEI, LAEF, LApEF, LASr, and LASr-c decreased in the gestational hypertension group (all P<0.05). Compared with the control group and gestational hypertension group, LAd, IVSd, LVd, LVMI, E/e′ LAVmin, LAVmax, LAVpreA, LAVImax, LAEV, LAScd, and LAScd-c increased, and LVEF, LAEF, LAEI, LApEF, LASr, and LASr-c decreased in the preeclamptic group, and the differences were statistically significant (all P<0.05). The results of multiple Logistics regression showed that LAVmax, LAScd-c and LASr were the indicators relevant to risk stratification of HDPs(β=0.344, 0.216 and -0.249, respectively, all P<0.05). ROC analysis showed when the cut-off value of left atrial strain parameter LASr was 30.5%, the AUC, sensitivity, and specificity were 0.725, 0.58, 0.90, respectively; when the cut-off value of LAVmax was 44.5 ml, the AUC, sensitivity, and specificity were 0.662, 0.80, and 0.56, respectively; and when the cut-off value of LAScd-c was -17.5%, the AUC, sensitivity, and specificity were 0.706, 0.56, and 0.78, respectively. Conclusions:Left atrial remodeling occured in pregnant women with hypertensive disorders, their reserve and conduit function were impaired, and aggravated with the progress of the disease. The four-dimensional parameters LASr, LAVmax, and LAScd-c were relevant indicators for risk stratification of HDPs. In predicting the severity of HDPs, LASr has high diagnostic value and good specificity; LAVmax and LAScd-c can be considered as supplementary parameters to predict the risk stratification of HDPs.
ABSTRACT
Objective:To investigate the effect of continuous balloon pressure monitor in children with postoperative tracheal intubation after congenital heart disease(CHD).Methods:Children admitted to the intensive care unit after CHD surgery were selected and divided into two groups using a random number table.Under the same treatment principles, the intervention group used a continuous balloon pressure monitor to manage the balloon pressure, and the control group used a manual balloon pressure meter.The clinical outcomes of two groups were compared.Results:A total of 84 children were enrolled, including 40 in intervention group and 44 in control group.There were no significant differences in age, sex, intubation depth and intubation type between two groups(all P>0.05).The rates of ventilator leakage in the intervention and control groups were 17.5% and 20.5%, respectively, and the rates of misaspiration in two groups were 0 and 6.8%, respectively, with no statistically significant differences(all P>0.05).The duration of mechanical ventilation in intervention group was longer than that in control group[median ventilator time 44.0(41.7, 73.5)h vs.43.0(38.9, 60.5)h, P=0.024], but the rates of abnormal balloon pressure(10.0% vs.81.8%, P<0.001), the rate of laryngeal edema after withdrawal(2.5% vs.18.2%, P=0.031)and the rate of vocal difficulties(7.5% vs.25.0%, P=0.032)were lower than those in control group, and the differences were statistically significant. Conclusion:Continuous balloon pressure monitoring can automatically maintain balloon pressure in the normal range, reduce complications associated with artificial airways, and have a positive effect on the maintenance of the airway in children.
ABSTRACT
Objective:To explore the changes of left atrial volume and function in patients with early diabetic nephropathy by four-dimensional auto left atrial quantification (4D Auto LAQ).Methods:Forty patients with early diabetic nephropathy (early diabetic nephropathy group), 40 patients with type 2 diabetes (diabetes group) in Henan Provincial People′s Hospital from March 2020 to April 2021 were selected, and 36 healthy volunteers (control group) were collected during the same period. The parameters of conventional echocardiography were measured, and the four-dimensional volume probe was used to obtain the complete left atrial volume image in 5 cardiac cycles. The 4D Auto LAQ software on the EchoPAC workstation was used for analysis to obtain the left atrial volume and strain indicators: left atrial (LA) maximum volume (LAVmax), left atrial minimum volume (LAVmin), pre-systolic volume (LAVpreA), left atrial volume index (LAVImax), left atrial emptying volume (LAEV), left atrial emptying fraction (LAEF), and long axis and circumferential strains in left atrial reserve phase, pipeline phase and systolic phase (LASr, LASr-c; LAScd, LAScd-c; LASct, LASct-c). The differences of these parameters among 3 groups were analyzed.Results:There were no significant differences in interventricular septum end-diastolic thickness(IVSd), left ventricular posterior wall end-diastolic thickness(LVPWd), left ventricular end-diastolic dimension(LVIDd), left ventricular ejection fraction(LVEF), and E/A (ration of early to late diastolic peak flow velocity of mitral orifice) among 3 groups (all P>0.05), and left atrial diameter(LAD), relative wall thickness(RWT), and E/e′ (ration of early diastolic peak flow velocity of mitral orifice to early diastolic velocity of lateral mitral annulus) among 3 groups were significantly different (all P<0.05). Further pairwise comparison results showed that LAD was only significantly different between the early diabetic nephropathy group and control group ( P=0.001 2), and the differences in RWT and E/e′ were statistically significant among 3 groups (all P<0.05). There were no significant differences in LAEV, LAScd-c, and LASct-c among 3 groups (all P>0.05), and LAVmin, LAVmax, LAVpreA, LAVImax, LAEF, LASr, LAScd, LASct, and LASr-c among the 3 groups were significantly different (all P<0.05). The pairwise comparison showed that, compared with the control group and the diabetes group, LAVmin, AVpreA, and LAVImax in the early diabetic nephropathy group were increased, and LAEF, LAScd, LASct, and LASr-c were decreased (all P<0.05). Compared with the control group, LAVmax, LAVImax and LASct in the diabetes group were increased, and LAEF, LAScd, and LASr-c were decreased (all P<0.05). Conclusions:4D Auto LAQ technology can quantitatively evaluate the changes in left atrium volume and function in patients with early diabetic nephropathy. Patients with early diabetic nephropathy have an increase in left atrium volume and a decrease in strain value.
ABSTRACT
Objective:To evaluate left ventricular myocardial work in pregnant women with impaired glucose tolerance(IGT) in the third trimester by the non-invasive technical parameters of pressure-strain loop(PSL), and to explore its predictive value of risk of perinatal adverse events.Methods:From October 2020 to October 2021, 70 pregnant women of IGT and 50 healthy pregnant women in Henan Provincial People′s Hospital were included, and a 75 g oral glucose tolerance test(OGTT) was performed at 24-28 weeks. Then their routine obstetric examinations were followed up until one week postpartum and perinatal adverse events were recorded, such as diabetic mother-infant syndrome, macrosomia, et al. After 36 weeks of pregnancy before childbirth, echocardiography was performed and dynamic images of 3-5 cardiac cycles at apical four-chamber view, three-chamber view, and two-chamber view were recorded.Simultaneously, pressure-strain loop(PSL) curve, left ventricular global longitudinal strain(GLS), global work index(GWI), global constructive work(GCW), global wasted work(GWW) and global work efficiency(GWE) were calculated through the EchoPAC 203 workstation. Then the differences of all parameters were compared between the two groups. And a prediction model for perinatal adverse events was built by binary logistic regression, and ROC curve was used to analyze the prediction efficiencies of the prediction model and each independent influencing factor.Results:Compared with the control group, the absolute values of GLS, GWI and GCW of IGT group were lower(all P<0.05). The incidence of perinatal adverse events of the IGT group, including adverse pregnancy outcomes and neonatal adverse outcomes, was higher than that in the control group( P<0.05). According to logistic regression model, the GLS, GWI, GCW and 2-hour postprandial blood glucose(2-hPBG) were independent influencing factors for perinatal complications(all P<0.05); in addition, ROC curve anaysis showed the area under the curve of the predictive model based on the influencing factors, GLS, GWI, GWE and 2-h PBG were respectively 0.903, 0.820, 0.879, 0.854 and 0.771. Conclusions:The parameters of PSL can quantitatively assess the changes of left ventricular myocardial work in pregnancy women with IGT; and the incidence of perinatal adverse events in IGT pregnant women is higher; GWI, GCW, the models constructed based on GLS, GWI, GCW and 2-hPBG have potential values in predicting the risk of perinatal adverse events.
ABSTRACT
Objective:To monitor and collect data information through failure mode and effect analysis (FMEA) and establish a data information system for nursing quality sensitive indicators.Methods:From July 2019 to July 2021, FMEA was used to evaluate the formation process of nursing quality sensitive index data, formulate specific improvement measures, and compare the proportion of risk priority index (risk priority number, RPN) value and index data informatization before and after the implementation.Results:Before the application of FMEA in nursing quality sensitive index data information management, the RPN value of index data element confirmation, index definition understanding, record specification, problem solving limitation, information communication and system data integration were (362.00 ± 101.56), (539.90 ± 174.39), (603.20 ± 128.71), (395.10 ± 184.83), (448.90 ± 185.58), (334.80 ± 107.74) points, while those after the intervention were (17.10 ± 9.96), (30.90 ± 31.66), (42.40 ± 28.99), (30.30 ± 33.94), (16.30 ± 17.02), (18.90 ± 19.27) points, with statistical significance ( t values were 9.11 to 14.74, all P<0.05). The proportion of sensitive index data informatization increased from 46.43% (39/84) to 95.51%(85/89). Conclusions:Using FMEA mode to manage the data information is effective and feasible for the realization of sensitive index information data.
ABSTRACT
Objective:To compare the clinical characteristics of congenital chylothorax in preterm and term infants.Method:From January 2011 to December 2019, the clinical data of infants with congenital chylothorax admitted to our hospital were retrospectively analyzed. The infants were assigned into preterm group (<37 weeks) and term group (≥37 weeks) according to their gestational age. The general information, clinical manifestations, laboratory results, treatment and prognosis of the two groups were compared.Result:A total of 34 infants with congenital chylothorax were included, including 11 premature infants and 23 term infants. No significant differences existed in gender, delivery mode, prenatal diagnosis of pleural effusion, congenital heart disease/chromosome abnormality, birth asphyxia, dyspnea, fetal edema, and location of effusion between the two groups ( P>0.05). Compared with term group, preterm group had significantly fewer leukocytes [3 245(1 007, 7 403)×10 6/L vs. 10 214(6 233,16 458)×10 6/L] and lower protein level [(28.1±7.6) g/L vs. (33.3±6.3) g/L] in the pleural fluid ( P<0.05). No significant differences existed in the proportion of pleural lymphocytes between the two groups ( P>0.05). The proportion of mechanical ventilation (MV) in the preterm group was statistically higher than that the term group [100%(11/11) vs. 65.2%(15/23)], and the duration of MV was statistically longer than the term group [(16(10,25) d) vs. (1(0,11) d)] ( P<0.05). No significant differences existed between the two groups in the application of other treatment options (thoracentesis/drainage, fasting, octreotide and erythromycin pleural injection), time needed for the disappearance of effusion, duration of hospital stay and cure/improvement rate ( P>0.05). Conclusion:Preterm infants may have lower leukocyte count and protein level in the pleural effusion than the term infants. Both preterm and term infants have higher proportion of lymphocytes in the pleural effusion fluid. Although most preterm infants need ventilator support after delivery, most of them achieve complete remission after conservative treatment and the overall prognosis is as good as term infants.
ABSTRACT
Objective:To investigate the sedative effect after congenital heart disease surgery in children under the bi-spectral index monitoring(BIS).Methods:A prospective cohort study was performed, we selected 264 children with congenital heart disease who were admitted to the cardiac intensive care unit at Shanghai Children′s Medical Center from September 2018 to August 2019, 126 cases in the intervention group, and 138 cases in the control group.The control group used Ramsay sedation score to evaluate the sedative effect, meanwhile the intervention group was evaluated by Ramsay sedation score and BIS.The incidence of adverse events related to extubation performed within 8 hours after congenital heart disease surgery, and the length of stay in ICU between two groups were compared.The average mechanical ventilation time of the patients whose mechanical ventilation time was more than 8 hours in two groups was compared.The use of sedative drugs midazolam and morphine in children with mechanical ventilation time for more than 24 hours and liver damage, and the incidence of respiratory depression during ventilator withdrawal were analyzed.Results:In children with early extubation, there were 62 cases in the intervention group and 70 cases in the control group.Compared with the control group, the intervention group had a low incidence of extubation-related adverse events (including unplanned extubation, dysphoria after sputum aspiration, and inhalation inhibition after extubation). The average mechanical ventilation time in the intervention group[(8.18±1.95)h] was less than that in the control group[(9.53±1.37)h, P<0.05] of the patients whose mechanical ventilation time was more than 8 hours but less than 24 hours.In children with mechanical ventilation time more than 24 hours, 28 cases were in the intervention group and 35 cases in the control group.The average doses of midazolam and morphine in the intervention group[(1.82±0.40)μg/(kg·min), (8.64±3.03)μg/(kg·h)] were less than those in the control group[(2.73±0.79) μg/(kg·min), (14.32±5.01)μg/(kg·h), all P<0.05]. Among the 28 children in the intervention group with mechanical ventilation time more than 24 hours, 13 cases had liver damage, and 15 cases of the 35 children in the control group had liver damage.The average doses of midazolam and morphine in the intervention group[(1.42±0.51)μg/(kg·min), (6.88±2.17)μg/(kg·h)] were lower than those in the control group[(2.25±0.62)μg/(kg·min), (11.88±3.56)μg/(kg·h), all P<0.05]. The incidence of inhalation inhibition in the intervention group was lower than that in the control group ( χ2=48.303, P<0.05). Conclusion:The sedation after congenital heart disease surgery in children under the BIS is effective.
ABSTRACT
Objective:To explore the application value of real-time three-dimensional echocardiography (RT-3DE) in evaluating the characteristics and regularities of left atrial volume and function changes in patients with hyperthyroidism and hyperthyroid heart disease.Methods:Fifty-six patients who were diagnosed with hyperthyroidism and hyperthyroid heart disease without treatments in Henan Provincial People′s Hospital from March 2020 to September 2020 were selected. They were divided into hyperthyroidism group(30 patients) and hyperthyroid heart disease group (26 patients). Another 30 healthy volunteers were selected as the control group. The following parameters were obtained by RT-3DE left atrial automatic quantification technology, left atrial minimum, maximum, presystolic volume index(LAVImin, LAVImax, LAVIpreA), left atrial passive, active emptying volume index and stroke volume index (LAVIp, LAVIa, LAVIEV), left atrial passive, active, total ejection fraction(LApEF, LAaEF, LAEF), during left ventricular systole, early diastole, late diastole left atrial longitudinal strain (LASr, LAScd, LASct) and circumferential strain (LASr-c, LAScd-c, LASct-c). The differences of the above parameters between the two groups were compared.Results:Compared with the control group, LAVImax, LAVIpreA, LAaEF, LAVIEV, LAVIa, LASr, LASct-c increased and LApEF decreased in the hyperthyroidism group (all P<0.05). While, LAVImin, LAVImax, LAVIpreA and LAVIEV increased, and LAaEF, LApEF, LAEF, LASct, LAScd-c and LASr-c decreased in hyperthyroid heart disease group(all P<0.05). Compared with the hyperthyroidism group, LAVImin, LAVImax and LAVIpreA in hyperthyroid heart disease group were further increased, while LAEF, LAaEF, LASr, LASr-c, LASct, LASct-c and LAScd-c were decreased (all P<0.05). LAEF were positively correlated with LASr and LASr-c ( r=0.617, 0.837; all P<0.01), LApEF were positively correlated with LAScd and LAScd-c ( r=0.620, 0.800, all P<0.01), LAaEF were positively correlated with LASct and LASct-c ( r=0.680, 0.727; all P<0.01). Conclusions:In the patients with hyperthyroidism, the left atrial reserve and systolic function are increased, which are still in the compensation stage, and the pipeline function is decreased. The left atrial reserve, pipeline and systolic function in the hyperthyroid heart disease patients are all decreased, and the pipeline function may be impaired earlier than the systolic and reserve function.

Conclusions It is essential to maintain normal valvular function to prevent the progress of myocardial deterioration . LSendo and LSepi can be used to sensitively identify early left ventricular systolic dysfunction in BAV patients with normal LVEF .
ABSTRACT
Objective To study the clinical features of early-onset Group B streptococcal(GBS) sepsis to improve the management of early-onset GBS sepsis.Method To review the clinical data of 27 cases of early-onset GBS sepsis in the Hospital over the past 5 years (January 2013 to November 2017),and analyze its clinical features,laboratory results,complications,prognosis and perinatal characteristics.Result A total of 27 cases of early-onset GBS sepsis were enrolled within 5 years,accounting for 0.85‰ (27/31 936) of total hospitalized patients over the same period.Among them,6 were premature infants and 21 full-term infants.The time of onset was within 24 hours.In all the cases,except for one full-term infant with fever as the initial symptom,the remainder had dyspnea as the initial symptom,accompanied by poor response and low poor muscle tone.Among them,17 patients required assisted ventilation.One of the full-term infant treated with ECMO within 48 hours after birth because of dyspnea,pulmonary hypertension and persistent hypoxemia,etc.,and improved and discharged;another 10 patients needed hood oxygen supply.5 cases (18.5％,5/27) diagnosed with purulent meningitis.In complete blood count,white blood cells ranged from (0.8～34.2)× 109/L,the minimum platelets counts was 16× 109/L,the maximum CRP was 249 mg/L,and maximum procalcitonin was＞ 100 ng/ml.All blood cultures were sensitive to penicillin.of the 27 patients,2 died despite of medical treatment,and 5 patients died as their parents worried about possible sequelae and discharged against medical advice.Therefore,tlhe total mortality rate was 25.9％ (7/27).All children were administered penicillin after the blood culture results were known,meropenem was subsequently added or replaced with vancomycin according to the clinical progress of the child.The remaining 20 patients recovered and discharged.Conclusion The clinical manifestation of early onset GBS septicemia is critically ill,with early onset,rapid progress,and high mortality.Special attention should be paid to high-risk cases during perinatal period,and early recognition with effective treatment would reduce morbidity and mortality.
ABSTRACT
Objective To summarize the clinical characteristics and prognosis of lacrimal gland adenoid cystic carcinoma with high-grade transformation (LACC-HGT).Methods A retrospective study was adopted.Seventeen patients with lacrimal gland adenoid cystic carcinoma (LACC) were collected from August 2008 to March 2017 in Tianjin Medical University Eye Hospital.Hematoxylin-eosin staining and immunohistochemical staining were performed on tumor sections of 17 LACC patients.According to the pathology results,the patients were divided into LACC-HGT group (6 patients) and non-LACC-HGT (NLACC-HGT)group (11 patients),and the clinical characteristics and prognosis of the two groups were analyzed by using Fisher's exact test and Log-Rank test.Results The medical histories,clinical features,imaging features,TNM staging and treatment protocols were not significantly different between the two groups (all at P＞ 0.05).The 2-year local recurrence rate,5-year distant metastasis rate and 5-year death rate of patients with LACC-HGT were significantly higher than patients with NLACC-HGT (all at P＜0.05).Survival analysis results showed that the survival time of LACC-HGT group was obviously shorter than that of NLACC-HGT group.Conclusions LACC-HGT accelerate the invasion process of local recurrence and distant metastasis,and enhance the death rate.The detection of HGT components should be considered in the process of LACC diagnosis.
ABSTRACT
Objective To estimate the effect of early fluid removal on the early postoperative recov-ery in children after surgical repair of congenital heart disease with enlarged right ventricle via a randomized trial. Methods One hundred and twenty patients with right-sided complex congenital heart defect who un-derwent cardiac surgery by cardiopulmonary bypass during January 2017 to June 2017 were enrolled and were divided into two groups,Group-E and Group-C,when the hemodynamics was stable within 3 hours after the surgery. Patients in Group-E were treated with early fluid removal,but Group-C remained conventional thera-py. The data of the hemodynamics and outcomes were collected from the postoperative day to the 2nd day post-operation. Results Fluid removal therapy was started in Group-E at (4. 39 ± 0. 85) h postoperatively vs (10. 17 ± 2. 77) h in Group-C (P < 0. 05). Patients in Group-E showed lower extravascular lung water index (ELWI),lower fluid overload and lower NT-proBNP compared with patients in Group-C on the first day of post-operation(P < 0. 01). Also, the advantages remained in Group-E on the second day but the ELWI showed no remarkable difference. The rate of reintubation(P < 0. 05),the duration of mechanical ventilation and the length of ICU stay (P < 0. 01)were significantly reduced in Group-E. Conclusion In patients with right ventricle enlarged complex congenital heart defect who underwent cardiac surgery by cardiopulmonary bypass,utilizing early negative fluid balance when the hemodynamics are stable and the right ventricle is ob-viously enlarged could achieve negative fluid balance,get extubated and discharge from ICU earlier,also pres-ent lower extravascular lung water index, lower incidence of weaning-induced pulmonary edema and reintubation.

Objective To analyze and compare the clinical and laboratory features between patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA).Methods One hundred and forty-one patients with AS and 73 cases with nr-axSpA were recruited.Clinical and laboratory indexes of individuals were recorded in detail,Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Score (ASDAS) crp were calculated.Spondyloarthritis research consortium of Canada (SPARCC) score standard was used to evaluate the degree of bone marrow edema in sacr-oiliac joint under magnetic resonance imaging scanning.T test,rank test and x2 test were used for statistical analysis.Results The average age of patients with AS was obviously higher than that of patients with nr-axSpA (t=4.962,P＜0.01).Patients with AS were more often male,and those with nr-axSpA were more often female (82.0％ of the AS patients were men and 49.3％ of the nr-axSpA patients were men (x2=24.079,P＜0.01).Disease duration of AS was significantly longer than that of the nr-axSpA (Z=6.396,P＜0.01).The incidence of human leukocyte antigen (HLA)-B27 positive in AS was 89.4％,which was similar to that in patients with nr-axSpA (84.9％) (x2=0.884,P＞0.05).21.6％ (21 cases) of patients with AS had peripheral swollen joints,which was higher than that in nr-axSpA (2.2％,x2=8.861,P=0.003).Forty cases in AS had tender joints (41.2％),only 6 patients in nr-axSpA had tender joints (13.3％,x2=11.458,P＜0.01).Serum erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) levels in patients with AS were clearly higher than those in nr-axSpA (P＜0.01) patients.In AS,the patient global assessment (PGA),BASDAI and ASDAScrp value was significantly higher than that in nr-axSpA (P＜0.01).There were no differences in SPARCC score or incidence of bone marrow edema in sacroiliac joint in magnetic resonance imaging scanning between AS and nr-axSpA (P＞0.05).Percentage of patients with occipit-to-wall distance higher than 0 cm in AS was higher than that in nr-axSpA,and the mean distance of fingers to ground in AS was also higher than that in nr-axSpA (x2=19.844,P＜0.01;Z=5.724,P＜0.01).Chest expansion degree and Schboer's test in AS was much lower than that in nr-axSpA,respectively (Z=3.083,P=0.002;Z=5.103,P＜0.01).BASFI in AS was higher than that in nr-axSpA (Z=5.840,P＜0.01).The ratio of joint function in AS was obviously worse than that in nr-axSpA (x2=1 1.369,P=0.01).Conclusion Compared to patients with nr-axSpA,AS patients are male predominant,and have severer inflammation in clinical and laboratory findings and are worse in functional status.
ABSTRACT
Colorectal cancer stem cells are a small part of cell population with features of stem cell in the colorectal cancer tissues. Tumor stem cells have the self-renewal capability and have been considered as the root of tumor recurrence. They play an important role in the development, progression, relapse, metastasis, and resistance to chemoradiotherapy of tumors. The long-term clinical practice has proved that traditional Chinese medicine has particular advantage on the aspect of resisting tumor recurrence and metastasis. In recent years, with the deep understanding of the theory of colorectal cancer stem cells, the clinical and basic researches of traditional Chinese medicine compound, single herb and active ingredient become hot spots.
ABSTRACT
Objective To analyze the safety and effect of non-invasive pressure support ventilation in 32 patients by using a helmet and to give the appropriate way of patients who need non-invasive ventilation ( NIV) support after congenital heart disease surgery. Methods Patients over one year old after congential heart disease surgery were admitted in our Department of Cardiovascular Thoracic Surgery from July 2015 to December 2015. Patients who get clinically improved within one hour were divided into the early improved group( Group-E) ,otherwise they were classified to non-early improved group( Group-NE) . The general infor-mation,diagnosis, indication of NIV, ICU and hospital stay, complications, and mortality were collected. Results Thirty-two patients were engaged in this study,including 18 patients(56. 25%) in Group-E and 14 patients(43. 75%) in Group-NE. Patients who got improved in the first hour might have a higher incidence of avoiding reintubation[83. 33%(15/18) vs. 42. 86%(6/14),P=0. 02]. The heart rate,respiratory rate, pH,PaO2/FiO2 and lactate were improved in Group-E compared with Group-NE after the first hour by using helmet. At the end of NIV,the oxygenation showed no difference but the PaCO2 was lower in Group-E. In Group-E,the values showed a trend of improvement,while the values in Group-NE showed not only no statis-tical significance in different time points but also seemed to have a tendency of hypercapnia and reduced com-fort behavior scale in the end of NIV. There were 6 cases in Group-E and 10 cases in Group-NE developed ventilation associated pneumonia with the incidence of 33. 33%(6/18) and 71. 43%(10/14),respectively, which was significant difference (χ2 =4. 571,P =0. 03). The total duration of mechanical ventilation of Group-E was shorter than that of Group-NE [ ( 136. 72 ± 151. 49 ) h vs. ( 252. 79 ± 155. 33 ) h, P <0. 05 ] . Conclusion NIV through a helmet in children could be well tolerated and avoid re-intubation. Patients who get improved earlier may have more clinical advantages,such as less time of mechanical ventilation and lower incidence of postoperative complications. Early improvement can be considered as a valuable indicator wheth-er the patient needs to use NIV continuously.
ABSTRACT
Objective To explore the value of polymerase chain reaction(PCR) to detect pathogens in ventilator-associated pneumonia(VAP) in children undergoing congenital heart disease(CHD) operation. Methods Forty-eight children selected from 95 cases with VAP underwent CHD operation were admitted in the department of CICU in our hospital from November 2016 to July 2017.Sputum specimens were separately collected by the bronchoalveolar lavage(BAL) and endotracheal tube attracts(ETA) methods,and the patho-gens were detected by culture and PCR assay.Results Nineteen specimens were found to be positive after 72 h of culture.A total of 20 pathogens were detected and 2 samples were mixed infection(more than one pathogen),and the positive rate was 39.2%(19/48).For PCR assay,44 pathogens from 31 samples were detected for just 24 h,22 samples were single pathogen infection,9 samples were mixed pathogen infection, and the positive rate was 65.3%(31/48).Compared with culture method,PCR assay could sharply increase the detection rate of every pathogen.Besides,the positive rate of the BAL or ETA for PCR assay was almost the same(45/48). Conclusion PCR assay for detecting pathogens is rapid,accurate and effective,which should be combined with culture method to detect for infectious pathogen.The ETA is the desired method to collect the sputum of the patients.
ABSTRACT
Background Pterygium is one of the common ocular surface disorders,and the main drugs for pterygium include dexamethasone (DXM),interferon α-2b (IFN-α2b),mitomycin C (MMC),5-fluorouracil (5-FU),cyclosporin A (CsA) and tacrolimus (FKS06).However,the efficacy of these drugs on the fibroblasts from recurrence pterygium is unelucidated.Objective This study was to compare the efficacy of DXM,IFN-o2b,MMC,5-FU,CsA and FK506 on proliferation and apoptosis of recurrent pterygium-derived fibroblasts in vitro.Methods The specimens of recurrence pterygium were collected during surgery in Tianjin Medical University Ophthalmological Hospital from May 2015 to July 2016 under the written informed consent.Fibroblasts were isolated and cultured by explant culture method and identified by immunochemistry.DXM,IFN-α2b,MMC,5-FU,CsA and FK506 were added into the medium for 48 hours,respectively,and the cells cultured without drug were used as the control group.The inhibitory efficiency of different concentrations of DXM,IFN-α2b,MMC,5-FU,CsA and FK506 on the cell proliferation was assayed by cell counting kit-8 (CCK-8),and 50％ inhibiting concentration (IC50) of the drugs was calculated.The cells were treated by the IC50 dose of drugs for 48 hours,and cell apoptotic proportion and cell cycle were assessed by flow cytometry analysis.The expression of proliferating cell nuclear antigen (PCNA) in the cells after treated by drugs was detected by immunochemistry.Results Cultured cells grew well with the fusiform shape and radial arrangement.Vimentine showed the positive expression and keratin was absently expressed in the cells.The IC50 to the cells was (3.5×103±2.83×10-2)mg/L,(6.1×102±3.6×10-3)mg/L,(3.2×10-1±1×10-4)mg/L,(2.2× 101 ± 1.2× 10-3) mg/L,(6.3 × 101 ±2.5 × 10-3) mg/L and (6.0× 101 ± 0.0× 100) mg/L in the DXM,IFN-α2b,MMC,5-FU,CsA and FK506,respectively.In the 48 hours after treated by the IC50 drugs,the apoptotic ratio was (35.00± 3.21)％,(30.37±1.67)％,(26.11±0.75)％,(22.01±0.07)％,(20.95±1.68)％ and (19.85±0.52)％ in the IFN-α2b group,CsA group,MMC group,FK506 group,DXM group and 5-FU group,which was significantly higher than (11.38±2.18) ％ in the control group (all at P＜0.05).The cell proportion of G0/G1 phase,S phase and G2/M phase was (85.64±2.62)％,(5.29±1.56)％ and (2.73-±2.66)％ in the control group,and the cell proportion of G0/G1 phase was reduced,while that of S phase or G2/M phase was considerably increased in various drug groups (all at P＜0.05),with the blocking efficiency of cell cycle was in turn MMC,CsA,5-FU,DXM,IFN-α2b and FK506.The expressional rate of PCNA in the cells was (95.00 ± 2.00) ％,(82.67 ± 5.04) ％,(80.00 ± 2.78) ％,(64.00± 6.55)％,(38.00±3.00)％,(32.00±4.36)％ and (29.67±3.02)％ in the control group,FK506 group,DXM group,5-FU group,IFN-α2b group,CsA group and MMC group,showing a significant difference among the groups (F=25.995,P＜0.01),and the expressional rate of PCNA was significant lower in various drug groups than that in the control group (all at P＜0.05).Conclusions DXM,IFN-α2b,MMC,5-FU,CsA and FK506 are all able to inhibit the proliferation and promote the apoptosis of recurrent pterygium-derived fibroblasts in vitro,and MMC and CsA appear to have a stronger effect.
ABSTRACT
Objective To investigate the impact of a single sub-anesthetic dose of ketamine on postoperative emotional reactions of anxiety and depression during colorectal tumors surgery. Methods A total of 42 patients undergoing selective colorectal surgery,aged 18 to 65 years,were randomly divided into ketamine group (group K)and control group (group C).After induction of an-esthesia,a single intravenous injection of 0.3 mg/kg ketamine and saline were used in Group K and group C 5 minutes before the operation respectively.The intravenous analgesia program was identical between the two groups.The patients??emotional reactions (anxiety,depression)were assessed using the Hospital Anxiety and Depression Scale (HAD),the quality of recovery was assessed using the QoR-40 questionnaire on the day before operation and within postoperative 48 hours respectively.Pain was estimated by the visual analog scale (VAS)and sedation was assessed with Ramsay score 30 mi-nutes after extubation.The time of anesthetic end and extubation were recorded.The complications during anesthesia and recovery such as cough, agitation 30 minutes extubation were recorded. Results The HAD-A and HAD-D scores of group K were lower than group C (P <0.05)48 h post-operatively.There was no difference on the QoR-40 score postoperative 48 h between the two groups. The patients??emotional state QoR-40 score of group K were higher than group C (P <0.05 ).The VAS scores 30 minutes after extubation of group K were lower than group C (P <0.05).There was no significant difference on sedation score 30 minutes postoperatively between the two groups.There was no significant difference in extubation time,cough,agitation and delirium between the two groups.There was no dizziness, nausea, vomiting or diplopia 30 minutes after extubation. Conclusion A single subanesthetic dose of ketamine can significantly reduce the scores of postopera-tive anxiety and depression,improve the quality of recovery,and no postoperative adverse reactions increased.
