Objective To establish a regression equation for risk factors of refeeding syndrome (RFS) in critically ill elderly patients and analyze the relevant intervention measures. Methods Clinical materials of 154 critically ill elderly patients treated in Intensive Care Unit (ICU) from January 2021 to March 2023 were retrospectively analyzed, and they were divided into RFS group (n=51) and non-RFS group (n=103) according to incidence condition of RFS. The influencing factors of RFS were analyzed by Logistic regression model; the predictive values of predictors for RFS were analyzed by receiver operating characteristic (ROC) curve; the relevant Logistic regression equations were constructed and verified, and relevant nursing interventions were formulated. Results The incidence of RFS in critically ill elderly patients was correlated with the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, the Nutritional Risk Screening 2002 (NRS2002) score, invasive mechanical ventilation, fasting time before feeding, D-dimer level, nutritional intake methods, and pre-feeding blood phosphorus, potassium and magnesium levels (P < 0.05). Logistic regression analysis showed that APACHE Ⅱ score, NRS2002 score, nutrient intake methods and pre-feeding blood phosphorus and potassium levels were the independent risk factors of RFS in critically ill elderly patients (P < 0.05). The ROC curve results showed that the values of area under the curve (AUC) of APACHE Ⅱ score, NRS2002 score, nutritional intake methods, pre-feeding blood phosphorus and potassium levels, and the combined predictor in predicting the incidence of RFS in critically ill elderly patients were 0.754, 0.723, 0.707, 0.783, 0.774 and 0.859, respectively (P < 0.05). The Logistic regression equation for RFS was as follow: L=0.085×APACHE Ⅱ score-0.337×NRS 2002 score+0.537×nutrient intake methods-0.776×pre-feeding blood phosphorus level-0.207×pre-feeding blood potassium level+0.942. The predictive value of this equation was good, and targeted nursing interventions could be formulated based on this equation. Conclusion The regression equation of risk factors can be used for clinical prediction of the RFS risk in critically ill elderly patients, and clinical nursing interventions can be formulated based on the regression equation to prevent the occurrence of RFS.

Objective:To investigate the factors associated with delay in anticoagulant therapy in patients with cerebral venous sinus thrombosis (CVST) and its effect on outcome.Methods:Patients with CVST admitted to Changhai Hospital, Naval Medical University from January 2010 to August 2021 were retrospectively enrolled. Patients were divided into early anticoagulation group and late anticoagulation group by the median time interval from first symptom to initiation of anticoagulation. The modified Rankin Scale was used for outcome assessment at 90 d after onset. 0-2 scores were defined as good outcome and 3-6 were defined as poor outcome. Demographic and clinical data were compared for the early versus late anticoagulation group and for the good versus poor outcome groups. Multivariable logistic regression was used to identify independent influencing factors of delay in anticoagulation and the correlation of delay in anticoagulation with poor outcome. Results:A total of 131 patients were included, their age was 40.07±15.11 years old, and 68 (51.91%) were male. Of these, 65 patients (49.62%) were in the early anticoagulation group and 14 (10.69%) were in the poor outcome group. Compared with the late anticoagulation group, the early anticoagulation group had a significantly higher proportion of patients with seizures and brain parenchymal damage as well as higher D-dimer levels on admission, while the proportion of patients with visual impairment/papilloedema was significantly lower (all P<0.05). Compared with the good outcome group, the poor outcome group had significantly higher proportions of patients with seizures, dyskinesia, impaired consciousness, low Glasgow Coma Scale score, and brain parenchymal damage as well as higher D-dimer, total cholesterol and low density lipoprotein cholesterol levels, sites of thrombus involvement were more common in the superior sagittal and straight sinuses, and significantly lower proportions of patients with headache and lower albumin levels on admission (all P<0.05). Multivariate logistic regression analysis showed that visual impairment/papilloedema (odds ratio [ OR] 0.119, 95% confidence interval [ CI] 0.030-0.473; P=0.002) and brain parenchymal damage ( OR 1.341, 95% CI 1.042-1.727; P=0.023) were independently associated with a delay in anticoagulation treatment, and a delay in anticoagulation treatment ( OR 6.102, 95% CI 1.185-30.504; P=0.030) and D-dimer level on admission ( OR 1.299, 95% CI 1.141-1.480; P<0.001) were the independent predictors of poor outcome in patients with CVST. Conclusions:Visual impairment/papilloedema and absence of brain parenchymal damage on cranial imaging are the independent risk factors for delay in anticoagulation in patients with CVST. The delay in anticoagulation is strongly associated with the poor outcome in patients with CVST.

Primary intrahepatic stones (PIS) is a refractory disease with a high incidence rate in southwest China, and some patients still require surgery again or even more times after initial treatment. Many studies in recent years have shown that some specific flora can colonize in the intrahepatic bile duct, leading to chronic infection and inflammation of the biliary system, and these specific types of flora, called "stone-causing flora", can produce metabolites such as β-glucuronidase and play an important role in the formation of pigmented stones. This article analyzes the role of stone-causing flora in the pathogenesis of PIS, so as to provide more treatment options for PIS patients.

Objective:To observe the clinical effect of scraping therapy on lumbar disc herniation (LDH) with different syndromes.Methods:Using the convenient sampling method, a total of 30 non-emergency LDH patients who were admitted to Department of Orthopedics and Traumatology of Yangzhou Hospital of Traditional Chinese Medicine from July 2017 to June 2018 were selected as the research objects. Among them, there were 11 cases of qi stagnation and blood stasis syndrome, 8 cases of damp-heat obstruction syndrome, 7 cases of cold-damp obstruction syndrome and 4 cases of liver and kidney deficiency syndrome. Du meridian, the bladder meridian of Foot Taiyang, as well as Jiaji (EX-B2) in pathological or painful sections, Ashi point, Shenshu (BL 23) , and Weizhong (BL 40) were mainly scraped. The treatment interval is 2~5 days (the marks of scrapping fade) , twice of scrapping as a treatment course and a total of 3 courses involved in the whole treatment. Japanese Orthopaedic Association (JOA) Score, Visual Analogue Scale (VAS) , serum interleukin-1 β (IL-1β) and interleukin-10 (IL-10) were compared before and after scraping.Results:Compared with those before scraping, the JOA score increased, the VAS decreased, the serum IL-1β content decreased and the serum IL-10 content increased after scraping, and the differences were sttaistically significant ( P<0.01) . Among them, the JOA scores of patients with qi stagnation and blood stasis syndrome and cold-damp obstruction syndrome were higher than those of damp-heat obstruction syndrome and liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . The levels of serum IL-10 in patients with qi stagnation and blood stasis syndrome, damp-heat obstruction syndrome and cold-damp obstruction syndrome were higher than those in patients with liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . Conclusions:The curative effect of scraping in the treatment of LDH is definite, and the curative effect is better for excessive syndromes.

Objective:To explore the research status, research focus and development trend of nursing human resource allocation in nursing homes in China.Methods:The article on nursing human resource allocation in nursing homes in China was systematically retrieved from China National Knowledge Infrastructure (CNKI), VIP and WanFang Data, and the retrieval time limit was from the establishment of the database to June 2022. CiteSpace was used to analyze the amount of articles, authors, institutions, funds and keywords, and draw a knowledge map.Results:A total of 890 articles were included. The number of articles and the support of national level funds were growing. The cooperation network among authors was extensive but not deep enough, and a core group of authors was not formed. A core journal group was formed. The research institute with the largest number of articles was the School of Nursing of Peking University. The article was mainly distributed in Beijing, Shanghai, Guangzhou and other first tier cities. The high-frequency keywords were "combination of medical care and nursing care" "supply" "demand" "talent training" and " care service for the aged", which could be clustered into 11 tags. The keyword cluster atlas showed that the combination of medical care and nursing care had always been the mainstream research direction in the field of nursing human resource allocation in nursing homes in China. "Qualitative research" "rural care for the aged " "care model for the aged " and "care industry for the aged " would become the emerging development trend in this field.Conclusions:The research on the nursing human resource allocation in nursing homes in China is growing. The research focuses on the combination of medical care and nursing care, talent training, care industry for the aged, and the supply and demand of care service for the aged. In the future, we should take the combination of medical care and nursing care as the leading mode, constantly improve our elderly care service system, build a nursing human resource allocation mode with Chinese characteristics in nursing homes, and promote the healthy aging development of society.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.

Objective:To systematically review the effects of the traditional Chinese medicine compound based on astragalus and angelica on bone marrow suppression after chemotherapy.Methods:Randomized controlled trials (RCTs) about the traditional Chinese medicine compound based on astragalus and angelica for bone marrow suppression after chemotherapy for malignant tumors were retrieved from Cochrane Library, PubMed, Web of Science, CINAHL, OVID, SinoMed, CNKI, VIP, and Wanfang Databases. The search period was from the establishment of the database to September 2019. The literatures were screened and the data were extracted independently by two researchers and RevMan 5.3 was used for Meta-analysis.Results:Totally 15 RCTs were included, involving 1 019 patients. Meta-analysis results showed that there were statistically significant differences in peripheral blood leukocytes [ SMD=1.32; 95% CI (0.76, 1.89) ; P<0.000 01], platelets [ MD=25.05; 95% CI (8.00, 42.10) ; P=0.004], hemoglobin [ MD=24.14; 95% CI (16.34, 31.94) ; P<0.000 01] and clinical symptoms [ RR=1.38; 95% CI (1.25, 1.52) ; P<0.000 01] between the chemotherapy group, the chemotherapy combined with the western medicine group and the traditional Chinese medicine compound group. Conclusions:The traditional Chinese medicine compound based on astragalus and angelica can improve the level of peripheral blood cells, reduce bone marrow suppression, and improve clinical symptoms and quality of life of patients with cancer after chemotherapy. However, due to the low quality of the included literature and the large heterogeneity of some of the results, more rigorously designed high-quality RCTs are needed for further verification.

Objective? To expLore the effects of Home FaLL Hazards Assessment (HFHA) on the incidence rate of home faLLs and recovery of hip function in patients receiving totaL hip arthropLasty (THA). Methods? TotaLLy 423 patients who received uniLateraL THA for the first time in the Department of Orthopedics, Nanjing Drum Tower HospitaL admitted from JuLy 2015 to JuLy 2017 were seLected by convenient sampLing and divided into the controL group (n=203) and the treatment group (n=220). Patients in the controL group received conventionaL postoperative nursing care and discharge guidance, whiLe the home faLL hazards of patients in the treatment group were evaLuated by HFHA in addition to conventionaL postoperative nursing care and discharge guidance. Nursing care was provided to them based on the assessment resuLts. The joint function score at discharge and 3 months after discharge, the incidence rate of faLLs over the past one year and the severity of injury caused by faLLs were compared between the two groups. ResuLts? There was no statisticaL difference in Harris index and BartheL index scores between the two groups at discharge (P＞ 0.05). Harris index and BartheL index scores 3 months after discharge were statisticaL differences in both groups (P＜0.05). 55 faLLs occurred over the past one year in the controL group, 7 of them with moderate or above injuries, whiLe 35 faLLs occurred over the past one year in the treatment group, 1 of them with moderate or above injuries. There were statisticaL differences in the incidence rate of faLLs and injury degrees between the two groups (P＜0.05). ConcLusions? HFHA, when used to assess the home faLL hazards, enabLes THA patients to know and note the high-risk hazards contributing to faLLs in their environment of rehabiLitation and effectiveLy reduces the patients home faLLs by improving the home environment.

Effective expression of pIFN-α in recombinant Pichia pastoris was conducted in a 5 L fermentor. Ethanol accumulation during the late glycerol feeding period inhibited heterologous protein expression. Comparative transcriptome analysis was thus performed to compare the gene transcription profiles of Pichia pastoris KM71H in high and low ethanol concentration environments. The results showed that during the glycerol cultivation stage, 545 genes (265 up-regulated and 280 down-regulated) were differentially expressed with ethanol stress. These genes were mainly involved in protein synthesis, energy metabolism, cell cycle and peroxisome metabolism. During the methanol induction stage, 294 genes (171 up-regulated and 123 down-regulated) were differentially expressed, which were mainly related to methanol metabolism, amino acid metabolism and protein synthesis. Ethanol stress increased protein misfolding and reduced structural integrity of ribosome and mitochondria during cultivation stage, and led to the failure of endoplasmic reticulum stress removal and damaged amino acid metabolism during induction stage in Pichia pastoris.
