Objective:To describe the current status and trends in the outcomes and care practices of extremely preterm infants at 22-25 weeks′ gestation age from the Chinese Neonatal Network (CHNN) from 2019 to 2021.Methods:This cross-sectional study used data from the CHNN cohort of very preterm infants. All 963 extremely preterm infants with gestational age between 22-25 weeks who were admitted to neonatal intensive care units (NICU) of the CHNN from 2019 to 2021 were included. Infants admitted after 24 hours of life or transferred to non-CHNN hospitals were excluded. Perinatal care practices, survival rates, incidences of major morbidities, and NICU treatments were described according to different gestational age groups and admission years. Comparison among gestational age groups was conducted using χ2 and Kruskal-Wallis tests. Trends by year were evaluated by Cochran-Armitage and Jonckheere-Terpstra tests for trend. Results:Of the 963 extremely preterm infants enrolled, 588 extremely preterm infants (61.1%) were male. The gestational age was 25.0 (24.4, 25.6) weeks, with 29 extremely preterm infants (3.0%), 88 extremely preterm infants (9.1%), 264 extremely preterm infants (27.4%), and 582 extremely preterm infants (60.4%) at 22, 23, 24, and 25 weeks of gestation age, respectively. The birth weight was 770 (680, 840) g. From 2019 to 2021, the number of extremely preterm infants increased each year (285, 312, and 366 extremely preterm infants, respectively). Antenatal steroids and magnesium sulfate were administered to 67.7% (615/908) and 51.1% (453/886) mothers of extremely preterm infants. In the delivery room, 20.8% (200/963) and 69.5% (669/963) extremely preterm infants received noninvasive positive end-expiratory pressure support and endotracheal intubation. Delayed cord clamping and cord milking were performed in 19.0% (149/784) and 30.4% (241/794) extremely preterm infants. From 2019 to 2021, there were significant increases in the usage of antenatal steroids, antenatal magnesium sulfate, and delivery room noninvasive positive-end expiratory pressure support (all P<0.05). Overall, 349 extremely preterm infants (36.2%) did not receive complete care, 392 extremely preterm infants (40.7%) received complete care and survived to discharge, and 222 extremely preterm infants (23.1%) received complete care but died in hospital. The survival rates for extremely preterm infants at 22, 23, 24 and 25 weeks of gestation age were 10.3% (3/29), 23.9% (21/88), 33.0% (87/264) and 48.3% (281/582), respectively. From 2019 to 2021, there were no statistically significant trends in complete care, survival, and mortality rates (all P>0.05). Only 11.5% (45/392) extremely preterm infants survived without major morbidities. Moderate to severe bronchopulmonary dysplasia (67.3% (264/392)) and severe retinopathy of prematurity (61.5% (241/392)) were the most common morbidities among survivors. The incidences of severe intraventricular hemorrhage or periventricular leukomalacia, necrotizing enterocolitis, and sepsis were 15.3% (60/392), 5.9% (23/392) and 19.1% (75/392), respectively. Overall, 83.7% (328/392) survivors received invasive ventilation during hospitalization, with a duration of 22 (10, 42) days. The hospital stay for survivors was 97 (86, 116) days. Conclusions:With the increasing number of extremely preterm infants at 22-25 weeks′ gestation admitted to CHNN NICU, the survival rate remained low, especially the rate of survival without major morbidities. Further quality improvement initiatives are needed to facilitate the implementation of evidence-based care practices.

Objective:To explore the influence factors of neurodevelopmental disorders in children with SCN8A-related early-onset epilepsy through analyzing their clinical characteristics and following up their neurodeve-lopmental status. Methods:A retrospective analysis was carried out on 21 children (13 males and 8 females, the age ranged from 4 months to 8 years, average 31.6 months)with SCN8A-related early-onset epilepsy treated in Guangzhou Women and Children′s Medical Center and Kunming Children′s Hospital between January 2017 and February 2021.All patients underwent whole-exome sequencing and Sanger sequencing.The pathogenicity was estimated according to the American College of Medical Genetics and Genomics guidelines.The clinical data of all patients were also collected, including the age of onset of the disease, forms of seizures, seizure frequency, neurological development at onset, electroencephalogram (EEG) and brain magnetic resonance imaging (MRI). Besides, the patients were followed up to acquire the effect of sodium channel blockers after the onset of seizures, the process or improvement of neurodeve-lopment, EEG evaluation and neurodevelopmental outcomes.Patients were grouped based on data analysis results.The Fisher′s exact test was conducted to measure the effect of various factors on the neurodevelopmental process and outcome, and corresponding coe-fficients were calculated. Results:The average onset age of 21 patients was 0-9 months.The follow-up duration was 4 months-8 years.Three cases died.Sixteen cases (76.2%) had early infantile epileptic encephalopathy (EIEE), 5 cases (23.8%) had epilepsy without encephalopathy, and 1 case had benign infantile epilepsy.Fourteen cases (66.7%) belonged to drug resistant epilepsy.Only one child showed normal neurodevelopment.Eleven children showed delayed neurodevelopment, but improvement was observed.Nine children were retrogressed and stagnated in terms of neurodevelopment.Small age at onset ( Fisher=9.517, P=0.020, r=0.571), high seizure frequency ( Fisher=10.512, P=0.003, r=0.572), EEG background ( Fisher=10.512, P=0.003, r=0.572), epileptic discharges ( Fisher=8.288, P=0.008, r=0.542), and EEG changes before and after treatment ( Fisher=10.437, P=0.009, r=0.586) were important factors affecting the neurodevelopmental process.Neurodevelopmental outcome was normal in only 1 case, 1 child belonged to mild mental retardation (MR), 7 children belonged to moderate MR, 3 children belonged to severe MR, and 9 children belonged to profound MR.Statistical analysis indicated that the clinical phenotype ( Fisher=10.059, P=0.004, r=0.739) and drug resistance ( Fisher=13.706, P=0.001, r=0.640) were significantly correlated with neurodevelopmental outcomes.However, the forms of seizures, EEG findings at onset and mutation sites were not related to neurodevelopmental disorders. Conclusions:Most children with SCN8A-related early-onset epilepsy are accompanied with neurodevelopmental retardation of varying degrees.Epileptic encephalopathy and poor response to drug treatment will lead to severe neurodevelopmental disorders.

Objective:To investigate the current situation of activity of daily living (ADL) among the community elders in Mianyang City in Sichuan Province and analyze its influencing factors, so as to provide reference for improving the ADL of the community elders.Methods:Using the convenient sampling method, from April 2020 to December 2021, a total of 17 259 community elders (≥65 years old) in 3 counties/districts in Mianyang City in Sichuan Province were selected as the research objects, and The Elderly Ability Assessment Standard Table was used to investigate them. A total of 17 259 questionnaires were sent out in this study and 16 482 were effectively received, with the effective recovery of 95.50%.Results:Among the 16 482 community elderly, a total of 20.59% (3 394/16 482) had ADL impairment, including 2 557 (75.34%) with mild ADL impairment, 517 (15.23%) with moderate ADL impairment and 320 (9.43%) with severe ADL impairment. The results of binomial Logistic regression analysis showed that age, educational level, marital status, children's status, mental state and social participation ability, perception and communication ability were the influencing factors of ADL among the elderly in community ( P<0.05) . Conclusions:The ADL impairment rate of the elderly in the community in Mianyang City is relatively high. Community medical staff should focus on the elderly. For those with low educational level, no spouse, children, impaired mental state and social participation ability and impaired perception and communication ability, the community medical staff give targeted interventions as soon as possible to improve the abilities of daily living of the elderly in the community.

Objective:To evaluate the efficacy and safety of reperfusion therapy in patients with wake-up stroke (WUS) under the guidance of "tissue-window" by comparing with patients with non-WUS who received reperfusion therapy within "time-window".Methods:Two hundred and thirty-five acute ischemic stroke patients admitted to our hospital from January 2018 to December 2019 were enrolled in our study. Patients with non-WUS received reperfusion therapy within "time-window"; patients with WUS accepted multimodal CT examination at Emergency right after admission, Mistar software was used to reconstruct CT perfusion imaging (CTP) images, and reperfusion therapy was given to these patients after the judgement of "tissue-window". The differences of clinical data, prognoses, and safety indexes were compared between patients with WUS and non-WUS.Results:In these 235 patients, 45 patients were with WUS and 190 were with non-WUS. As compared with patients with non-WUS, those with WUS had significantly lower percentages of patients with hypertension history and patients accepted intravenous thrombolysis ( P<0.05). In 153 patients accepted intravenous thrombolysis, 23 patients were with WUS and 130 were with non-WUS; the time from admission to intravenous thrombolysis in WUS patients was significantly longer than that in non-WUS patients ( P<0.05); the clinical data, prognoses, and safety indexes showed no significant differences between these patients with WUS and non-WUS ( P>0.05). In 82 patients accepted bridging thrombectomy and direct thrombectomy, 22 patients were with WUS and 60 were with non-WUS; the clinical data, prognoses, and safety indexes showed no significant differences between these patients with WUS and non-WUS ( P>0.05). Conclusion:By comparing with patients with non-WUS who received reperfusion therapy within "time-window", reperfusion therapy is effective and safe for WUS patients under the guidance of multimodal CT "tissue-window".

Objective:To construct the scheme of palliative care for nursing undergraduates based on competency outcomes and performance assessment (COPA) model, and to provide reference for palliative care course.Methods:The research period is from March to December in 2020. Based on Lenburg's COPA model, the first draft of the curriculum scheme was constructed through literature research and focus group interview, and 23 experts were invited to modify the content to determine the final versions of curriculum scheme.Results:The response rate of the two rounds of questionnaires were 100.0% and 91.3% respectively, and the expert authority coefficient were 0.80 and 0.82 respectively. After two rounds of Delphi procedure, the opinion of the experts was nearly consistent. The curriculum scheme contains 49 curriculum objectives, 70 theoretical contents, 5 practical contents and 9 teaching methods.Conclusions:The curriculum scheme of palliative care for nursing undergraduates based on COPA model is scientific and practical, which can provide guidance for undergraduate nursing.

Objective To investigate the correlation between the insertion depth of the left-sided double-lumen tube (DLT) and some specific body landmarks in order to guide left-sided DLT intubation. Methods Ninety-five adult patients who underwent thoracic surgery were chosen, and the age (A), sex (S), height (H), weight (W), distance between the cricothyroid membrane and upper notch of the sternum angle (L), size of the left-sided DLT (F), and predicted depth of intubation (y) were recorded. After anesthesia induction, the final corrected insertion depth of the left-sided DLT (Y) were recorded using fiberoptic bronchoscopy. The Y and y were compared.Linear regression and Pearson's correlation analysis were used to analyze the data. Results There was no difference between the Y and y (P＞ 0.05). The Y was significantly correlated with H, W, and L (P ＜ 0.01), and was not correlated with A (P＞ 0.05). Three linear regression equations for H, L, and Y were obtained. H and L were linearly dependent on Y, and the determination coefficients R2 were 0.43 (Y=7.285+0.128 H) and 0.41 (Y=19.305+0.866 L), respectively. Using both H and L as the independent variables, the determination coefficient R2 was 0.56 (Y=8.127+0.087 H+0.559 L). Conclusion The linear regression equation Y=8.127+0.559 H+0.087 L could be used as a rapid method to assess the insertion depth of the left-sided DLT. However, the ideal insertion depth of the left-sided DLT still needs to be confirmed using fiberoptic bronchoscopy.

Objective To observe the expression change of melanoma-associated antigen(MAGE)-A9 in colorectal cancer (CRC)tissue and to explore its significance.Methods The samples in 23 cases of initially diagnosed CRC in the Affiliated Hospital of Nantong University from January 2006 to December 2008 were collected.The quantitative real-time(qRT)-PCR was adopted to detect MAGE-A9 mRNA expression in cancer tissue and corresponding paracancerous tissue.Its correlation with the clinicopatho-logical features and prognosis was analyzed.Results The positive rate of MAGE-A9 in CRC tissue was significantly higher than that in paracancerous normal tissue(P<0.05).MAGE-A9 protein expression in CRC was related to the clinicopathological features such as tumor differentiation degree(P=0.011),TNM stage(P=0.003),tumor infiltration depth(P=0.001)and lymph node me-tastasis(P=0.003).The survival analysis showed that the expression of MAGE-A9 was closely related to the prognosis of CRC pa-tients.Conclusion MAGE-A9 expression is increased in CRC tissue,suggesting the poor prognosis.

Objective To provide reference for clinical pharmacists participating in pharmacotherapy of low molecular weight heparin calium-induced thrombocytopenia.Methods Clinical pharmacists carried out pharmaceutical care for a patient with chronic cor pulmonale with acute exacerbation of chronic asthmatic bronchitis in the use of low molecular weight heparin calium,who developed progressive thrombocytopenia,and helped clinicians to manage adverse reaction and select subsequent treatment drug.Results The suggestions were adopted by clinicians.The platelets of patients gradually recovercd without thrombosis events.Condusion Participation of clinical pharmacists in the treatment of low molecular weight heparin calium induced-thrombocytopenia can effectively improve the prognosis of patients and ensure the safety in drug use.
