Objective:To investigate the correlation of lung ultrasound score and poor prognosis in internal shock patients in intensive care unit (ICU).Methods:The clinical data of 200 shock patients admitted to the ICU of Wuzhou Red Cross Hospital from July 2019 to June 2021 were selected for study. According to the prognosis of patients, they were divided into survival group and death group. The clinical data of shock patients in ICU with different prognosis were analyzed by single factor analysis, multiple factor regression analysis and predictive value analysis.Results:All patients were followed up. The end point of the study was death or transfer from ICU. The follow-up period was 28 days, with a median of 16 days. The 28-day survival rate (OS) of all patients was 62.5%(125/200). The Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, prothrombin time (PT), Fbg, D-dimer(D-D), lactic acid, oxygenation index and lung ultrasound score of the patients in the survival group and the death group were significantly different (all P<0.05), while other indexes were not significantly different (all P>0.05). The results of COX multivariate analysis showed that APACHE Ⅱ score, lactate, and lung ultrasound score were independent prognostic factors of shock patients in ICU (all P<0.05). The survival curves of patients with different lung ultrasound scores were significantly different ( P<0.05). The higher the lung ultrasound score, the lower the 28-day survival rate ( P<0.05). The receiver operating characteristic(ROC) curve analysis showed that the area under curve (AUC), sensitivity and specificity of predicting the prognosis of patients with lung ultrasound score were 0.753, 76.0% and 71.2%, respectively; The AUC , sensitivity and specificity of APACHE Ⅱ score were 0.774, 77.3% and 79.2% respectively; The AUC, sensitivity and specificity of lactic acid were 0.783, 81.3% and 68.8% respectively, with no significant difference (all P>0.05). Conclusions:The lung ultrasound score , lactic acid and APACHE Ⅱ scores are independent risk factors affecting the prognosis of ICU shock patients, and have considerable predictive value.

The content validity index of the scale level was 0.984, and the cumulative variance contribution rate was 59.688%.Conclusions:The reliability and validity of the Elderly Inpatient Falls Prevention Knowledge, Attitude and Practice Scale for Full-time Caregivers are good, and can be used as a tool to evaluate the full-time caregiver knowledge, attitude and practice for preventing falls in elderly inpatients.

Objective Through factor analysis of the quantified syndrome information of 558 cases of kidney yang deficiency syndrome,the constructing feature of kidney yang deficiency syndrome was revealed,which provides clinical data support for the objectification,standardization and normalization of kidney Yang deficiency syndrome.Methods Firstly,the frequency analysis of symptoms,tongue and pulse signs of 558 patients with kidney Yang deficiency syndrome was carried out,and then the main syndrome information of the patients with kidney Yang deficiency syndrome was quantified.Finally,the common factors and their representative variables of kidney Yang deficiency syndrome were screened out through factor analysis,and the constructing feature of kidney Yang deficiency syndrome was analyzed combined with TCM syndrome knowledge.Results Eight common factors with eigenvalues greater than 1 were extracted by principal component analysis,and the cumulative contribution rate was 60.483%.After the factor rotation,the representative variables with the absolute value of load coefficient greater than 0.45 in each common factor were selected.The representative variables of F1 are afraid of cold and fond of warmth(0.947)and intolerance to cold(0.932).The representative variables of F2 are waist pain(0.754),waist and knee weakness(0.720)and cold in waist and knees(0.466).The representative variables of F3 are depression(0.749),insomnia(0.711)and diarrhoea(0.470).The representative variables of F4 are thin fur(0.819)and white fur(0.768).The representative variable of F5 are tinnitus and deafness(0.687),frequent nocturnal urination(0.591)and decreased libido(0.587).The representative variables of F6 are pulse sinking(0.766)and pulse weakness(0.736).The representative variables of F7 is thready pulse(0.942).The representative variable of F8 is pale tongue(0.961).External syndrome of disease location involved in these common factors are waist,bone,brain,ear,anterior Yin,posterior Yin and reproductive function.The disease nature involved in these common factors is deficiency and cold.Conclusion The basic constituent units of kidney Yang deficiency syndrome include disease location syndrome elements and disease nature syndrome elements.The disease location is kidney,and the abnormal changes of kidney location are mainly external symptoms of waist,bone,brain,ear,anterior Yin,posterior Yin and reproductive function.Its disease nature is deficiency and cold.Yang deficiency leads to external cold.Yang Qi deficiency can not warm the body surface resulting in the appearance of external cold syndrome.

Objective:To evaluate the effectiveness of remote pulmonary rehabilitation in the elderly COPD patients in order to provide evidence-based basis for the clinical practice and promotion of remote pulmonary rehabilitation.Methods:We searched databases including Web of Science, PubMed, Cochrane Library, Embase, CINAHL,China Biology Medicine disc, China National Knowledge Internet, VIP, and Wanfang and selected all randomized controlled trials (RCTs) that reported the effects of telerehabilitation on the elderly patients with COPD. The retrieval time was from the establishment of the database to April 26, 2023. Meta-analysis was performed by RevMan 5.3.Results:A total of 24 RCTs involving 2 980 patients with COPD were finally included. Meta-analysis results showed that telerehabilitation in the elderly patients with COPD can improve the lung function (FEV 1/FVC) ( MD=2.09, 95% CI 0.30-3.89, P<0.05), quality of life ( MD=-0.66, 95% CI -1.05--0.26, P<0.05), anxiety ( MD=-0.69, 95% CI -1.32--0.05, P<0.05) and depression ( MD=-0.81, 95% CI -1.59--0.04, P<0.05), and the subgroup for the lung function (FEV 1/FVC) of the elderly patients with COPD emphasized that physical activity, intervention time ≤24 weeks, intervention frequency 1-3 times per week, and use of network platform, there were significant differences between those subgroups (all P<0.01). But there was no statistically significant difference in improving the exercise capacity ( MD=-1.54, 95% CI -14.83-11.75, P>0.05). Conclusions:Telerehabilitation in pulmonary can be considered a supplementary intervention for improving the lung function (FEV 1/FVC), the quality of life and the psychological condition on the elderly patients with COPD.

Objective:To optimize the Manchester needs tool for injured children (MANTIC) scale , and evaluate its reliability and validity among injured children. Methods:The MANTIC scale was optimized through Delphi expert consultation and pre-tests. From March 2023 to June 2023 , a total of 317 injured children admitted in 7 level A tertiary hospitals in Zhejiang and Shandong provinces and their families were surveyed with general data, optimized MANTIC scale, and EuroQol 5-dimension health questionnaire for youth (EQ-5D-Y). Item analysis was conducted on the data of the 317 patients collected with optimized MANTIC scale through the test for homogeneity and value-based decision-making method and the content validity test of the scale was evaluated with item-level content validity index (I-CVI) and scale-level content validity index (S-CVI). It was evaluated with KMO test values and Bartlett′s test of sphericity to determine whether the scale was suitable for exploratory factors. The number of common factors was determined based on the K1 criterion and scree plot to further obtain the structural validity of the scale of the item load value. The correlation validity of the scale was evaluated with the correlation coefficient of the optimized MANTIC scale and EQ-5D-Y. The reliability of the scale was tested with Cronbach alpha coefficient and Guttman split-half reliability coefficient. Results:A total of 332 questionnaires were distributed, among which 317 valid ones were collected, with a response rate of 95.6%. The test of homogeneity in the item analysis showed that the correlation coefficient between each item and the total score of the scale was 0.40-0.80. The results of the value-based decision-making method showed that the critical ratio of high-and low-scored groups was 6.08-28.01. The quality of all the items met the retention requirements so that the reliability and validity tests could be continued. Validity test found that I-CVI was 0.83-1.00, consistent S-CVI was 0.83, and mean S-CVI was 0.95. In structural validity analysis, the KMO value was 0.96, and the Chi-square value of Bartlett′s test of sphericity was 10755.76 ( P<0.01). A total of 9 common factors were extracted with the K1 criterion (eigen value>1), and the scree plot indicated 9 common factors with a cumulative variance contribution rate of 73.46%. Factor extraction and rotation showed that the load value of each item of the scale ranged from 0.589 to 0.874. The correlation coefficient of the optimized MANTIC scale and EQ-5D-Y was r= 0.55 ( P<0.01).Reliability test showed that the Cronbach alpha coefficient of the total scale and all dimensions was 0.96 and 0.77-0.98, and the Guttman split-half reliability coefficient was 0.76 and 0.73-0.98. Conclusion:The optimized MANTIC scale can attain good reliability, validity, consistency and stability, and can reflect the concept to be expressed and the content to be evaluated, indicating that it can be used to evaluate the injury rehabilitation needs of injured children and their families throughout the entire treatment process.

Objective:To describe the clinical features of pediatric biotinase deficiency (BTD) manifested as spinal cord disease.Methods:The clinical data of a child with spinal cord lesions due to biotinase deficiency, diagnosed in Beijing Children′s Hospital in 2020, were collected. The cases with complete clinical data retrieved on literature reported in China National Knowledge Infrastructure, Wanfang Data knowledge Service Platform and PubMed (up to August 2021) by using search terms of biotinase deficiency, pediatric, spinal cord, myelopathy and myelitis were summarized.Results:The patient was a 3 years and 5 months old boy with the main clinical manifestations of subacute progressive limb weakness and wheezing. Physical examination showed sparse hair, rough skin, spastic paraparesis and developmental delay. Cerebrospinal lactic acid was increased (5.67 mmol/L). Cranial magnetic resonance imaging (MRI) showed diffuse T 2/fluid attenuated inversion recovery hyperintensity of the midbrain, dorsal pons, edulla, periacqueductal grey and optic tracts. Spinal cord lesions were extended from the medulla up to the level of the conus. Urineketone bodies and 3-hydroxyisurate were increased. The activity of biotinidase was 0.27 pmol/min (3 mm disc), being 7% of mean normal serum activity. Genetic studies revealed homozygous mutation in the BTD gene [c.284T>A (p.I95N)]. After biotin supplementation for 6 months, the only evident abnormality was residual spasticity of lower limbs. Fourteen English literatures and 2 Chinese literatures including 18 cases were collected. The onset age was from 2 months to 15 years (median age was 4 years). Among them, 11 cases had cranial MRI abnormalities, of which all involved brain stem, 6 cases involved optic tracts and (or) optic chiasm. All 18 cases had spinal cord MRI abnormalities with longitudinally extensive lesion, mostly involved cervical and thoracic spinal segments, and 3 cases involved all spinal segments. Twelve cases received immunotherapy, and 6 were partially improved, 6 were completely invalid. After biotin supplementation, 12 patients had neurological disability. Conclusions:BTD should be included in the differential diagnosis of subacute myelopathy, regardless of the onset age. Early diagnosis and treatment can prevent irreversible neurological damage.

Objective:To explore the correlation among undergraduate nursing students' attitudes towards the aged, family intimacy and sense of meaning in life, so as to provide a reference for improving undergraduate nursing students' attitudes towards the aged.Methods:This study was a cross-sectional study. Convenience sampling was used to select 385 undergraduate nursing students from 3 universities in Shandong Province as the research objects. The survey was conducted using the General Information Questionnaire, Kogan's Attitudes toward Older People Scale (KAOPS) , Family Intimacy Subscale and Meaning in Life Questionnaire (MLQ) . The correlation among undergraduate nursing students' attitudes towards the aged, family intimacy and sense of meaning in life was analyzed by Pearson correlation. The influencing factors of undergraduate nursing students' attitudes towards the aged were analyzed by multiple linear regression. In this study, a total of 385 questionnaires were distributed and 348 valid questionnaires were returned with an effective response rate of 90.39%.Results:Among those undergraduate nursing students, the KAOPS total score was (165.58±23.24) , and the Family Intimacy Subscale score was (70.16±9.75) , and the MLQ total score was (52.84±9.58) . The score of Family Intimacy Subscale, the total score and the dimension scores of MLQ were positively correlated with the KAOPS total score and dimension scores of undergraduate nursing students ( r=0.190-0.450; P<0.01) . The results of multiple linear regression analysis showed that gender, experience in geriatric nursing practice, willingness to engage in geriatric nursing work, relationship with the aged, family intimacy, and sense of meaning in life were the influencing factors of undergraduate nursing students' attitudes towards the aged ( P<0.05) , explaining 30.1% of the total variation. Conclusions:Undergraduate nursing students generally have a positive attitude towards the aged, but there is still room for improvement. In the future, the intervention research on family intimacy and sense of meaning in life of undergraduate nursing students should be strengthened, so as to guide undergraduate nursing students to have a more positive attitude towards the aged and improve the quality of geriatric nursing services.

Objective:To explore the status quo of palliative care needs of patients with end-stage heart failure, and analyze its influencing factors.Methods:This study was a cross-sectional study. From December 2019 to December 2020, convenience sampling was used to select 83 patients with end-stage heart failure in a Heart Failure Treatment Center of a Class Ⅲ Grade A hospital in Qingdao as the research object. The General Information Questionnaire and the Palliative Care Needs Scale for Patients with End-stage Heart Failure were used to investigate the patients. Multiple linear regression was used to analyze the influencing factors. A total of 83 questionnaires were distributed and 76 valid questionnaires were returned with the valid response rate of 91.57%.Results:Among 76 patients with end-stage heart failure, the total score of the Palliative Care Needs Scale for Patients with End-stage Heart Failure was (110.87±20.77) , of which the information needs dimension score (29.61±6.69) was the highest. The results of multiple linear regression analysis showed that the serum sodium concentration, the number of comorbidities, and the educational background were the influencing factors of the palliative care needs of patients with end-stage heart failure ( P<0.05) , which explained 30.6% of the total variation of the palliative care needs. Conclusions:Patients with end-stage heart failure have a high demand for palliative care. Nursing staff should provide personalized palliative care for patients with end-stage heart failure according to their own characteristics.

Objective:To explore the phenotypes and genotypes of molybdenum cofactor deficiency type B (MoCD-B) manifested as Leigh-like syndrome.Methods:The clinical data, laboratory tests, neuroimaging and gene results of one patient diagnosed as MoCD-B at Beijing Children′s Hospital and Hebei Children′s Hospital in December 2018 were collected. Related literature was searched and reviewed at Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure and PubMed (up to September 2020) by using terms "MOCS2" "molybdenum cofactor deficiency" "Leigh-like syndrome,MOCS2" "molybdenum cofactor deficiency, Leigh-like syndrome". The phenotypes and genotypes of MoCD-B were summarized.Results:A 7 months and 14 days old boy with the chief complaint of "cough for 6 days, abnormal posture for 4 days and fever for 2 days" was admitted to Hebei Children′ Hospital on December 2018. His abnormal posture presented as opisthotonos accompanied with dysphagia, without seizures. His previous psychomotor development was described as normal. He was born at term after an uneventful pregnancy to non-consanguineous parents. Blood test showed a slightly increased lactic acid and a significantly decreased uric acid. Urine metabolism test showed an obviously increased xanthine and hypoxanthine. Brain magnetic resonance imaging showed hyperintense signal on T2 weighted image and fluid attenuated inversion recovery in bilateral globus pallidus and pedunculus cerebri. The patient was diagnosed with Leigh-like syndrome. No obvious improvement was achieved after cocktail therapy and symptomatic treatment. The whole exome sequencing showed that the patient carried a homozygous variant of MOCS2 gene, c.19G>T(p.Val7Phe), which was a previously reported pathogenic site in the literature and could cause MoCD-B. His parents carried a heterozygous variant respectively. A total of 41 MoCD-B cases with MOCS2 gene variants were collected through literature review and our study, among which 30 cases had full medical records. The onset ages of 23 (77%) cases were in neonate, manifesting with severe encephalopathy, including neonatal-onset intractable seizures, developmental delay, laboratory abnormalities included very low levels of serum and urinary uric acid, increased urinary levels of xanthine and hypoxanthine. Cranial imaging showed cerebral atrophy, cystic encephalomalacia, etc. The onset ages of 7 patients varied from 5 months to 23 years. Four cases had normal psychomotor development before disease onset. Neurological disorders appeared acutely or exacerbated after external triggers and all of them had basal ganglia involvement. Among the 30 cases, 3 cases had a relatively milder phenotype with the ability of brief communication and walking without or with support.Conclusions:Molybdenum cofactor deficiency is a rare disease. Most cases had severe phenotypes and poor outcomes, but some cases may have mild phenotype. MoCD-B caused by MOCS2 gene variants may manifest as Leigh-like syndrome with a normal psychomotor development before the trigger of infection strike. Hypouricemia, xanthinuria and hypoxanthinuria can be indicators of the disease. The presence of MOCS2 gene variants would confirm a final diagnosis.

Characterized by impaired neuromuscular transmission, congenital myasthenic syndromes (CMS) are a group of genetic disorders.The main manifestations include fatigue and weakness of skeletal muscle, with most onset in infant or early childhood.The common cause of death is respiratory failure, with high disability rate.With the improvement of gene sequencing technology and the in-depth study on the structure and function of pathogenic proteins, the pathogenesis of the disease has been deeply understood in the past 20 years.Early diagnosis and treatment can significantly improve the symptoms in patients.In this manuscript, the etiology, clinical characteristics, diagnosis and treatment of CMS are reviewed.
