RESUMO
ObjectiveTo observe the effects of the kidney-tonifying and blood-activating prescription on the Wnt/β-catenin signaling pathway and uterine spiral artery remodeling in a mouse model of recurrent miscarriage and to explore its underlying mechanism. MethodA mouse model of normal pregnancy was established by mating CBA/J mice with BALB/c mice. A mouse model of recurrent miscarriage was established by mating CBA/J mice with DBA/2 mice. The modeled mice of recurrent miscarriage were randomized into model， dydrogesterone， and low- and high-dose Chinese medicine groups. The mice in normal pregnancy were used as the control group. Each group consisted of 10 mice， and the drug administration lasted for 14 days. After the treatment， the embryo absorption rate of each group was recorded. Hematoxylin-eosin （HE） staining was employed to observe the pathological morphology of the uterine decidua， and the physiological transformation rate of spiral arteries （SPA） was evaluated. Real-time polymerase chain reaction （Real-time PCR） and Western blot were performed to determine the mRNA and protein levels， respectively， of matrix metalloproteinases （MMP）-2， MMP-9， vascular endothelial growth factor （VEGF）， and Wnt/β-catenin signaling pathway. ResultCompared with the control group， the model group presented increased embryo absorption rate （P<0.05）， decreased physiological transformation rate of uterine SPA （P<0.05）， cellular swelling， degeneration， and disordered arrangement in the uterine decidua tissue， and down-regulated mRNA and protein levels of key factors involved in SPA remodeling （MMP-2， MMP-9， VEGF） and the Wnt/β-catenin signaling pathway （Wnt2， β-catenin， Cyclin D1， c-Myc） （P<0.05）. Compared with the model group， both the low- and high-dose Chinese medicine reduced embryo absorption rate （P<0.05）， increased SPA physiological transformation rate （P<0.05）， improved uterine decidua tissue morphology， and increased decidua vessel count. Furthermore， they up-regulated the mRNA and protein levels of MMP-2， MMP-9， VEGF， and proteins in the Wnt/β-catenin signaling pathway （P<0.05）. ConclusionRecurrent miscarriage is associated with impaired uterine spiral artery remodeling. The kidney-tonifying and blood-activating prescription can promote uterine spiral artery remodeling by activating the Wnt/β-catenin signaling pathway and promoting the expression of VEGF， MMP-2， and MMP-9， thus treating recurrent miscarriage.
RESUMO
BACKGROUND:The treatment of distal tibial fractures with soft tissue injury has always been challenging,and the new retrograde tibial nailing is a new choice.Up to now,there were few reports on the biomechanical properties between the new retrograde tibial nailing,anterograde intramedullary nailing and supercutaneous locking plate. OBJECTIVE:To explore the biomechanical stability of new retrograde tibial nailing,antegrade intramedullary nailing and supercutaneous locking plate in the treatment of distal tibial fractures with soft tissue injury using finite element analysis so as to offer a scientific foundation for clinical application. METHODS:The finite element model of transverse distal tibia fracture was established by relevant software utilizing the CT data of the tibia from a 42-year-old healthy male.Retrograde tibial nailing,antegrade intramedullary nailing and supercutaneous locking plate finite element models were assembled under the principle of fracture fixation.Finally,meshing,applying loads,and data processing were accomplished with the ANSYS 2019 software.Moreover,the stress distribution and displacement of the tibia and internal fixation of each model were compared. RESULTS AND CONCLUSION:(1)The displacement of fracture end in the three groups increased with the increase of load.In all mode loads,the average displacement of the fracture end was the least in the retrograde tibial nailing group,followed by the supercutaneous locking plate group,and the highest in the antegrade intramedullary nailing group.At 800 N vertical load,the displacement difference of the fracture end was statistically significant(P<0.05).There was no statistical significance in other load modes.(2)Under different loads,the tibial stress in the three groups was the highest in the middle of the tibia,and gradually decreased to the proximal and distal ends.The stress distribution of the tibial shaft was the highest in the retrograde tibial nailing group,followed by the supercutaneous locking plate group,and the least in the antegrade intramedullary nailing group.(3)Under different loads,the stress of the tibial stress raiser in the three groups was significantly higher in the supercutaneous locking plate group than in the other two groups,with statistical significance(P<0.05).(4)Under different loads,the stress of the fixators in the three groups was the largest in the supercutaneous locking plate group,followed by the retrograde tibial nailing group,and the minimum in the antegrade intramedullary nailing group.There were significant differences in the stress of fixator stress raiser among the three groups under different loading modes(P<0.05).(5)It is indicated that all three fixation methods have the good anti-rotation ability and axial stability.Retrograde tibial nail shows better biomechanical stability.
RESUMO
BACKGROUND:The treatment of distal tibial comminuted fractures with soft tissue injury has always been challenging.The new retrograde tibial nailing and supercutaneous locking plate are important treatment methods,but their strain and stress shielding at the fracture end during different periods of fracture healing and different load conditions have not been reported. OBJECTIVE:To explore the biomechanical stability of retrograde tibial nailing and supercutaneous locking plate in different periods of fracture healing by finite element analysis to offer a scientific foundation for clinical application and rehabilitation exercise. METHODS:The finite element model of distal tibial comminuted fracture was established by utilizing the CT data of the tibia from a 40-year-old healthy male.Retrograde tibial nailing,supercutaneous locking plate,and callus models were assembled in accordance with the principle of fracture fixation.The finite element analysis was performed using ANSYS software to compare the displacement of the fracture end,the stress shielding of the tibia,the stress of the callus,and the stress distribution of the tibia and the fixation device during different periods of fracture healing. RESULTS AND CONCLUSION:(1)The relative displacement of the tibial fracture decreased gradually with the healing of the fracture,and the displacement decreased significantly after 3 months.At 0 and 1 months after operation,the vertical displacement and total displacement of the supercutaneous locking plate group were higher than those in the retrograde intramedullary nail group.The Z-axis displacement(horizontal medial and lateral displacement)of the two fixation methods was more obvious than the X-axis and Y-axis,and the Z-axis displacement of supercutaneous locking plate group was the most obvious.The maximum Z-axis displacement of the two fixation methods was located on the outside of the tibia,and the minimum displacement was located on the inside of the tibia.(2)The stress shielding rate at different periods of fracture healing gradually decreased with time.The stress shielding rate of the retrograde intramedullary nail was higher than that of the supercutaneous locking plate at different stages of fracture healing.After 3 months,the stress shielding rate of the supercutaneous locking plate was reduced to about 4%,and the stress shielding rate of the retrograde intramedullary nail was reduced to about 40%.(3)The stress of the stress concentration site of the callus in the two fixation methods increased with the increase of the load,and the stress of the callus in the supercutaneous locking plate group was always greater than that in the retrograde intramedullary nail group.The maximum stress distribution of the callus was approximately equally distributed among the two modes of fixation,both in the lateral portion of the tibia.(4)As the fracture healed,the maximum stress of the tibia in the two groups decreased gradually,and the stress in the supercutaneous locking plate group was always greater than that in the retrograde intramedullary nail group.The average stress of the maximum stress area of the tibia in the supercutaneous locking plate group under 1 500 N load was 285 MPa,while that in the retrograde intramedullary nail group was 26 MPa.(5)As the fracture healed,the stress of the fixation device in the two groups decreased gradually,and the stress in the supercutaneous locking plate group was significantly higher than that in the retrograde intramedullary nail group.After 3 months,the stress of the two fixation devices decreased significantly.(6)It is indicated that in the early stage of fracture healing,the strain on the fracture end in the retrograde intramedullary nail group is small,and the maximum stress of the tibia is moderate,allowing early loaded.The fractured ends in the supercutaneous locking plate group had too large strain and too large maximum stress of the tibia,which needed to be partially loaded under protection and could not be fully loaded.In the middle and late stages of fracture healing,the tibial retrograde intramedullary nail and the supercutaneous locking plate could be completely loaded,and the stress shielding rate of the supercutaneous locking plate was significantly lower than the tibial retrograde intramedullary nail.
RESUMO
BACKGROUND:Long intergenic non-protein coding RNA 00707(LINC00707)and microRNA-423-5p(miR-423-5p)are both involved in the occurrence and development of osteoarthritis.Starbase predicts that LINC00707 and miR-423-5p have complementary sequences,but whether LINC00707 and miR-423-5p interact to regulate the progress of osteoarthritis still needs further research. OBJECTIVE:To investigate whether LINC00707 targets miR-423-5p to affect chondrocyte injury and inflammatory factor secretion in osteoarthritis. METHODS:Articular chondrocytes were divided into eight groups:(1)blank control group was given no treatment;(2)interleukin(IL)-1β group was cultured with 10 ng/mL IL-1β for 48 hours;(3)IL-1β+si-NC group was transfected with si-NC and then treated with 10 ng/mL IL-1β for 48 hours;(4)IL-1β+si-LINC00707 group was transfected with si-LINC00707 and then treated with 10 ng/mL IL-1β for 48 hours;(5)IL-1β+miR-NC group was transfected with miR-NC and then treated with 10 ng/mL IL-1β for 48 hours;(6)IL-1β+miR-423-5p group was transfected with miR-423-5p mimic and then treated with 10 ng/mL IL-1β for 48 hours;(7)IL-1β+si-LINC00707+anti-miR-NC group was co-transfected with si-LINC00707 and anti-miR-NC and then treated with 10 ng/mL IL-1β for 48 hours;(8)IL-1β+si-LINC00707+anti-miR-423-5p group was co-transfected with si-LINC00707 and anti-miR-423-5p and then treated with 10 ng/mL IL-1β for 48 hours.Relevant tests were performed at the end of the intervention. RESULTS AND CONCLUSION:Compared with the blank control group,the mRNA expression of LINC00707,apoptosis rate,protein expression of C-caspase3 and C-caspase9,and levels of tumor necrosis factor-α and IL-6 in articular chondrocytes were increased in the IL-1β group,while there was a decrease in miR-423-5p expression and IL-10 level(P<0.05).Compared with the IL-1β group,the mRNA expression of LINC00707,apoptosis rate,protein expression of C-caspase3 and C-caspase9,and levels of tumor necrosis factor-α and IL-6 in articular chondrocytes were decreased in the IL-1β+si-LINC00707 group,while miR-423-5p expression and IL-10 level increased(P<0.05).Compared with the IL-1β+miR-NC group,the protein expression of C-caspase3 and C-caspase9 and levels of tumor necrosis factor-α and IL-6 in articular chondrocytes were decreased in the IL-1β+miR-423-5p group,while miR-423-5p expression and IL-10 level increased(P<0.05).Compared with the IL-1β+si-LINC00707+anti-miR-NC group,apoptosis rate,protein expression of C-caspase3 and C-caspase9,and levels of tumor necrosis factor-α and IL-6 in articular chondrocytes were increased in the IL-1β+si-LINC00707+anti-miR-423-5p group,while miR-423-5p expression and IL-10 level decreased(P<0.05).To conclude,inhibiting LINC00707 by targeting miR-423-5p can reduce IL-1β-induced apoptosis and inflammation in articular chondrocytes.
RESUMO
BACKGROUND@#Antenatal corticosteroids (ACS) can significantly improve the outcomes of preterm infants. This study aimed to describe the ACS use rates among preterm infants admitted to Chinese neonatal intensive care units (NICU) and to explore perinatal factors associated with ACS use, using the largest contemporary cohort of very preterm infants in China.@*METHODS@#This cross-sectional study enrolled all infants born at 24 +0 to 31 +6 weeks and admitted to 57 NICUs of the Chinese Neonatal Network from January 1st, 2019 to December 30th, 2019. The ACS administration was defined as at least one dose of dexamethasone and betamethasone given before delivery. Multiple logistic regressions were applied to determine the association between perinatal factors and ACS usage.@*RESULTS@#A total of 7828 infants were enrolled, among which 6103 (78.0%) infants received ACS. ACS use rates increased with increasing gestational age (GA), from 177/259 (68.3%) at 24 to 25 weeks' gestation to 3120/3960 (78.8%) at 30 to 31 weeks' gestation. Among infants exposed to ACS, 2999 of 6103 (49.1%) infants received a single complete course, and 33.4% (2039/6103) infants received a partial course. ACS use rates varied from 30.2% to 100% among different hospitals. Multivariate regression showed that increasing GA, born in hospital (inborn), increasing maternal age, maternal hypertension and premature rupture of membranes were associated with higher likelihood to receive ACS.@*CONCLUSIONS@#The use rate of ACS remained low for infants at 24 to 31 weeks' gestation admitted to Chinese NICUs, with fewer infants receiving a complete course. The use rates varied significantly among different hospitals. Efforts are urgently needed to propose improvement measures and thus improve the usage of ACS.

RESUMO
The causes of obstructive azoospermia are complex, mostly permanent, and it is very rare to return to normal without medication or surgery. This article analyzes the changes in the course of a patient with obstructive azoospermia without surgery and medication and the delayed return to normal sperm density. The reasons for its self-recovery: it might be related to asymptomatic epididymitis and ejaculatory duct cysts. The possibility of self-recovery in patients with obstructive azoospermia due to specific etiologies.
RESUMO
Objective:To analyze the clinical features, treatment, and outcomes of fetal/neonatal atrial flutter (AFL) at the onset of the perinatal period to improve the management of this condition.Methods:This retrospective study analyzed the clinical data, treatment, and follow-up results of fetal/neonatal AFL cases transferred to Shanghai Children's Medical Center from November 2013 to August 2021. Clinical characteristics, cardioversion procedures, and outcomes were summarized. Descriptive method was used for statistical analysis.Results:A total of 21 fetuses/neonates presenting with AFL in the perinatal period were involved in this study, including 17 males and four females. Ten of them were born at full term, and 11 were preterms. All of the patients were delivered by cesarean section at 32 to 41 gestational weeks [ (36.6±1.9) weeks] with a birth weight of 2 130 to 4 450g [ (3 059±528) g]. Increased fetal heart rate was all detected after 32 weeks of gestation, and three of them were diagnosed with AFL by fetal echocardiography before being born. The heart rate remained elevated in all cases after birth. All were diagnosed as AFL based on an electrocardiogram on the day of birth, which showed a 2 to 6 over one ratio of atrioventricular conduction. Among the six cases of cardiac insufficiency and low blood pressure complicated by dyspnea and cyanosis, the symptoms were relieved in four cases after mask oxygenation and two cases after ventilation. Among the 21 cases, one was converted spontaneously to normal sinus rhythm and the other 20 recovered after medication or electrical cardioversion. Seven cases were initially treated by drug conversion with a success rate of 5/7 and hospitalized for 23 d (13-25 d). There was one with cardiac insufficiency before treatment and three newly developed cardiac insufficiency during treatment among the seven cases. Thirteen cases were offered electrical cardioversion initially, and the success rate of cardioversion was 12/13. There were five cases of cardiac insufficiency before treatment, while no new cases of cardiac insufficiency was reported during treatment. The duration of hospitalization was 11 d (9-14 d). Apart from one case, the rest 20 infants were followed up from one month to eight years old, and no recurrence was reported.Conclusions:For fetal/neonatal AFL with the onset during the perinatal period, the symptoms mainly manifest in late pregnancy. Its diagnosis depends on fetal echocardiography before birth or electrocardiogram after birth, and electrical cardioversion is a fast and effective measure. While the prognosis of perinatal-onset AFL is generally good.
RESUMO
Objective:To analyze the distribution of ages at the interhospital transfer of outborn very preterm infants in China and to compare their perinatal characteristics and outcomes at discharge and neonatal intensive care unit (NICU) treatment.Methods:A total of 3 405 outborn very premature infants with a gestational age of 24-31 +6 weeks who were transferred to the NICUs of the Chinese Neonatal Network (CHNN) in 2019 were included in this retrospective study. According to the age at transfer, they were divided into three groups: early transfer (≤1 d), delayed transfer (>1-7 d) and late transfer (>7 d) groups. Analysis of variance, t-test, Chi-square test (Bonferroni correction), Kruskal-Wallis test and Wilcoxon rank-sum test were used to compare the general clinical condition, treatment, and outcomes at discharge among the three groups. Results:The median gestational age was 29.7 weeks (28.3-31.0 weeks) and the average birth weight was (1 321.0 ± 316.5) g for these 3 405 infants. There were 2 031 patients (59.6%) in the early transfer group, 406 (11.9%) in the delayed transfer group and 968 (28.4%) in the late transfer group. Infants who received continuous positive airway pressure ventilation and tracheal intubation in the delivery room accounted for 8.4% (237/2 806) and 32.9% (924/2 805), respectively. A total of 62.7% (1 569/2 504) of the mothers received antenatal glucocorticoid therapy and the ratio in the early transfer group was 68.7% (1 121/1 631), which was higher than that in the delayed transfer group [56.1% (152/271), χ2=16.78, P<0.017] and the late transfer group [49.2% (296/602), χ2=72.56, P<0.017]. The total mortality rate of very premature infants was 12.7% (431/3 405), and the mortality rates in the early, delayed and late transfer groups were 12.4% (252/2 031), 16.3% (66/406) and 11.7% (113/968), respectively ( χ2=5.72, P=0.057). The incidences of severe intraventricular hemorrhage, late-onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge were all higher in the delayed and late transfer groups than in the early transfer group, respectively. The incidences of retinopathy of prematurity, retinopathy of prematurity requiring treatment and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge in the late transfer group were significantly higher than that in the delayed transfer group (Bonferroni correction, all P<0.017). In the late transfer group, the median age of very premature infants at discharge was 66.0 d (51.0-86.0 d), and the corrected gestational age at discharge was 38.9 weeks (37.1-41.2 weeks), and both were greater than those in the early transfer [48.0 d (37.0-64.0 d), Z=260.83; 36.9 weeks (35.7-38.3 weeks), Z=294.32] and delayed transfer groups [52.0 d (41.0-64.0 d), Z=81.49; 37.4 weeks (36.1-38.7 weeks), Z=75.97] (all P<0.017). Conclusions:Many very premature infants need to be transferred to higher-level hospitals after birth. The later the very premature infants are transferred, the higher the incidence of complications will be. It is suggested that intrauterine or early postnatal transport may improve the prognosis of very premature infants.
RESUMO
Objective:To systematically evaluate the dose-response relationships of resistance exercise intensity in frail elderly.Methods:A comprehensive search of randomized controlled trials on the dose-response relationships of resistance exercise for frail elderly in PubMed, Embase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Database. The documents that met the conditions were screened out, and after the data were extracted and the quality of the documents were evaluated, the RevMan 5.3 software was used for Meta analysis.Results:A total of 10 eligible randomized controlled trials were included in this study. The subjects of the study were 454 cases of frail and pre-frail elderly. After Meta analysis, there was a dose-response relationships between the training intensity of resistance exercise and the muscle strength, muscle endurance, and physical function of frail elderly. Both low-intensity and high-intensity resistance exercises can significantly increase the leg muscle strength of frail elderly people ( MD=4.58, 95% CI 3.34-5.82, P<0.05) and muscle endurance ( MD=12.27, 95% CI 6.54-17.99, P<0.05). Compared with low-intensity resistance exercise, high-intensity resistance exercise increased leg muscle strength of frail elderly people ( MD=7.97, 95% CI 0.85-15.09, P<0.05) and muscle endurance ( MD=6.94, 95% CI 5.21-8.66, P<0.05) showed more obvious advantages. The analysis of the results of the chair sitting test and the stairs climbing test shows that low-intensity resistance exercise has no obvious advantage in improving the physical function of frail elderly people, while high-intensity resistance exercise can significantly improve the physical function of frail elderly people ( MD=-5.8, 95% CI -7.3--4.29, P<0.05; MD=-1.20, 95% CI-2.17--0.23, P<0.05). Conclusions:Resistance exercise can significantly improve the muscle strength, muscle endurance and physical function of the frail elderly. High-intensity resistance exercise is more effective than low-intensity resistance exercise.

RESUMO
Objective:To analyze the correlation between capillary filling time (CRT) and lactate clearance rate in patients with septic shock, so as to provide reference for the clinical application of CRT in patients with septic shock.Methods:A prospective study was conducted on 70 patients with septic shock. CRT, mean arterial pressure (map) and sequential organ failure (SOFA) score, Acute Physiology and Chronic Health Evaluation Scoring System (APACHE Ⅱ) score, mechanical ventilation and lactate clearance rate were collected at 3 sites (forehead, knee and nail bed) respectively at 2 time points after admission and 6 hours after admission. The correlation between CRT changes and lactate clearance rate was compared.Results:When lactate clearance rate of more than 10% in 6 hours, the Pearson coefficients of the three sites were 0.823 for nail bed ( P<0.05), 0.232 for forehead and 0.254 for knee ( P>0.05). When lactate clearance rate of less than 10% in 6 hours, the Pearson coefficients of the three sites were 0.299 for nail bed, 0.247 for forehead and 0.254 for knee ( P>0.05). Conclusion:When lactate clearance rate of more than 10% in 6 hours, there is a good correlation between the CRT of nail bed and the lactate clearance rate of patients. The CRT of nail bed can be a practical tool for clinical evaluation of microcirculation.
RESUMO
Objective:To study the predictive value of hour-specific total serum bilirubin(TSB) nomogram combined with clinical risk factors in the risk of hyperbilirubinemia.Method:Perinatal clinical data of newborns born in Shanghai Pudong New Area Health Care Hospital for Women and Children, Shanghai Pudong New Area People's Hospital and Shanghai Pudong Hospital from August 2017 to July 2018 were collected in this prospective study. Transcutaneous bilirubin (TcB) was monitored before discharge from hospital. Enrolled neonates were followed up for 28 days. The patients were assigned to neonatal hyperbilirubinemia group (NHB) and non-hyperbilirubinemia group (Non-HB) according to the occurrence of hyperbilirubinemia. The predictive value of models for the risk of hyperbilirubinemia was evaluated by receiver operating characteristic (ROC) curves and Logistic regression analysis.Result:A total of 8 664 newborns were included in this study, with 1 196 cases of hyperbilirubinemia, with an incidence of 13.8%. Logistic regression analysis showed that maternal blood type O, premature rupture of membranes, male gender, gestational age 35~37 weeks, subcutaneous ecchymosis/cranial edema, and breastfeeding were independent risk factors for NHB ( P<0.05). The area under receiver operative characteristic curve (ROC) of predischarge bilirubin risk zone only was 0.874(95% CI 0.861~0.885, P<0.05)and for all independent risk factors was 0.664 (95% CI 0.647~0.680, P<0.05). The area under ROC curve was 0.891 (95% CI 0.880~0.902, P<0.05) by combining predischarge bilirubin risk zone with clinical risk factors. Conclusion:Predischarge bilirubin risk zone combined with clinical risk factors can reasonably predict neonatal hyperbilirubinemia well.
RESUMO
Infection is one of the most serious diseases during the neonatal period and the leading cause of neonatal death.Early virus detection is particularly important in the vulnerable infants hospitalized in modern, family centered NICUs.These units bear increasing risks of virus transmission as they provide kangaroo care, 24 hour visiting policies, and are not only open to parents and siblings, but do also encourage their involvement.Due to the atypical clinical features, susceptibility to mixed viral-bacterial infection, lower positive rate of detection, non-specific treatment options, and causing short-term as well as long-term complications or even death if the infection is severe.Thus, it is very important to recognize respiratory virus infection early to prevent and control its spread in neonatal wards.This article aimed to elaborate the susceptibility factors, common pathogens, detection methods and the management of prevention, and control of neonatal respiratory virus infection.
RESUMO
Objective@#To analyze the epidemiological history, clinical manifestations, treatment and the short-term prognosis of 31 cases of 2019 novel coronavirus(2019-nCoV) infection in children from six provinces (autonomous region) in northern China.@*Methods@#A retrospective analysis of the epidemiological history, clinical symptoms, signs, laboratory examinations, chest imaging, treatment and the short-term prognosis of 31 cases of 2019-nCoV was conducted. The patients were diagnosed between January 25th, 2020 and February 21st, 2020 in 21 hospitals in 17 cities of six provinces(autonomous region) of Shaanxi, Gansu, Ningxia, Hebei, Henan and Shandong.@*Results@#The age of the 31 children with 2019-nCoV infection was 7 years and 1 month (6 months -17 years). Nine cases (29%) were imported cases. Other 21 cases (68%) had contact with confirmed infected adults. One case (3%) had contact with asymptomatic returnees from Wuhan. Among the 31 children, 28 patients (90%) were family cluster cases. The clinical types were asymptomatic type in 4 cases (13%), mild type in 13 cases (42%), and common type in 14 cases (45%). No severe or critical type existed. The most common symptom was fever (n=20, 65%), including 1 case of high fever, 9 cases of moderate fever, 10 cases of low fever. Fever lasted from 1 day to 9 days. The fever of fifteen cases lasted for ≤3 d, while in other 5 cases lasted > 3 d. Other symptoms included cough (n=14, 45%), fatigue (n=3, 10%) and diarrhea (n=3, 9%). Pharyngalgia, runny nose, dizziness, headache and vomiting were rare. In the early stage, the total leukocytes count in peripheral blood decreased in 2 cases (6%), the lymphocytes count decreased in 2 cases (6%), and the platelet count increased in 2 cases (6%).Elevation of C-reactive protein (10%, 3/30), erythrocyte sedimentation rate(19%,4/21), procalcitonin(4%,1/28), liver enzyme(22%, 6/27) and muscle enzyme (15%, 4/27) occurred in different proportions. Renal function and blood glucose were normal. There were abnormal chest CT changes in 14 cases, including 9 cases with patchy ground glass opacities and nodules, mostly located in the lower lobe of both lungs near the pleural area. After receiving supportive treatment, the viral nucleic acid turned negative in 25 cases within 7-23 days. Among them, 24 children (77%) recovered and were discharged from hospital. No death occurred.@*Conclusions@#In this case series, 2019-nCoV infections in children from six provinces (autonomous region) in northern China are mainly caused by close family contact. Clinical types are asymptomatic, mild and common types. Clinical manifestations and laboratory examination results are nonspecific. Close contact history of epidemiology, nucleic acid detection and chest imaging are important bases for diagnosis. After general treatment, the short-term prognosis is good.

Objective:To establish a practical framework for critical ultrasonography to provide a basis for clinical practice.Methods:With reference to domestic and foreign literature, expert interviews and research groups developed a preliminary draft of the practice framework for critical ultrasonography, and conducted two rounds of consultation using the Delphi method.Results:A practical framework for critical ultrasonography was developed, including 5 primary indicators and 20 secondary indicators. In the two rounds of expert consultation, the expert′s positive coefficient was 100% and the authoritative coefficient was 0.836.Conclusions:Expert opinion has good coordination and high authority, which can provide clinical basis for ICU nurses to carry out ultrasound examination.
RESUMO
Objective:We reported nursing care of a patient with postpartum cardiomyopathy treated by extracorporeal membrane oxygenation (ECMO) combined with intra-aortic balloon pump (IABP), continuous renal replacement therapy (CRRT) and prone position ventilation.Methods:Multidisciplinary cooperation was made to guide the monitor of patients' condition. Refined integrated management measures of multi-equipment were adopted and standardized management process was formulated. Strict requirements were made in treatment and nursing care to prevent hospitalized infection, humanistic care and rehabilitation exercise were conducted to improve patient′s quality of life.Results:After 47 days of nursing care, the patient′s vital signs were stable, the condition was improved and then discharged.Conclusions:Close observation under the guidance of multiple disciplines is an important prerequisite for the treatment. Integrative management of multi-equipment, strict control of hospitalized infection, humanistic care and rehabilitation exercise can effectively improve the prognosis and quality of life of perinatal cardiomyopathy patient.
RESUMO
Objective:By building a patient safety oriented nursing-sensitive indicator system, this study aimed to help clinical evaluation and nursing for patients in prone position, to constantly optimize management of prone position and promote patient safety.Methods:First drew up initial indicators through literature search and personal interviews, then modified and finally formed the prone position nursing indicators within two rounds of experts consultation. Verified the indicators by evaluating nursing staff satisfaction after half-year′s implementation.Results:Finally, the indicator system included 9 first level, 13 second level and 71 third level indicators. The reliability of experts and the satisfaction of nurses were both high.Conclusions:With the purpose of patient safety, the nursing indicator system of prone position ventilation for critically ill patients are comprehensively covered ever aspect of key component. Specific effect needs to be further verified in the hospital management practice.
