RESUMEN
Renal fibrosis, especially tubulointerstitial fibrosis, is the most common pathway of all chronic kidney diseases progressing to end-stage renal diseases. Several adaptive reactions occur in renal tubular epithelial cells after chronic injury, such as changes in glycolipid metabolism, unfolded protein response, autophagy and senescence, epithelial-to-mesenchymal transition and G2/M cell cycle arrest. Maladaptive repair mechanisms can induce tubulointerstitial fibrosis. This article will discuss the molecular mechanism of these adaptive responses of renal tubular epithelial cells driving renal tubulointerstitial fibrosis, and provide a basis for exploring new drug targets for renal tubulointerstitial fibrosis.
RESUMEN
Objective:To develop and evaluate a rapid and sensitive point-of-care chemiluminescent assay(POC-CLIA)for β-human chorionic gonadotropin(β-HCG).Methods:POC-CLIA was constructed based on alkaline phosphatase(Alp)-AMPPD lumi-nescence system and magnetic particles(Mps)carrier.Performance of POC-CLIA,including sensitivity,precision,accuracy,linear dilution,specificity,stability,hook effect and clinical application were evaluated.Results:Detection limit of β-HCG was 0.71 mU/ml,linear detection range was 0.710～1.092×104 mU/ml,and was no hook effect up to 1.7×105 mU/ml.Intra and inter batch coefficients of variation were less than 10％,and could be stored stably at 37℃ for 10 days.Accuracy deviation was within±10％,so results were reliable.There was no cross-reactivity between interfering substances and anti-β-HCG antibdies.For detecting β-HCG in 100 clinical serum samples,results were highly correlated with those that were tested by clinical standard methods(R2=0.997 0).Turnaround time for single sample was less than 15 min and throughput could reach 200 T/h.Conclusion:This method is adequate that can be widely used in grassroots communities to help large-scale screening of pregnancy and related diseases.
RESUMEN
Femtosecond laser-assisted cataract surgery(FLACS)has been used for more than 10 years, with its safety and precision well-verified. In recent years, FLACS has been gradually applied to patients with glaucoma and cataracts, especially those patients with primary angle closure glaucoma(PACG). The unique anatomical characteristics of PACG increase the difficulty of lens extraction and potential complications in conventional phacoemulsification surgery, highlighting the distinct advantages of FLACS in these patients. Recently, the application of FLACS combined with minimally invasive glaucoma surgery(MIGS)in patients with open angle glaucoma, and goniosynechialysis(GSL)in patients with angle-closure glaucoma, and even in patients with filtering blebs after anti-glaucoma surgery, has been reported. The indications for FLACS are increasingly expanding. FLACS can cause a transient intraoperative increase in intraocular pressure(IOP), and ocular parameters can have a certain impact on IOP. The long-term effects on IOP require further research. More attention should be paid to the impact of FLACS on visual function in glaucoma patients and the related complications that may arise. This article reviews the application of FLACS in different types of glaucoma, its effects on IOP and visual function, specific complications, and application prospects.
RESUMEN
Malnutrition and dehydration are prevalent in the elderly poplulation, and obesity is also a growing problem, which pose a serious challenge to the nutritional management in geriatrics. In order to better guide clinical practice, the European Society for Clinical Nutrition and Metabolism (ESPEN) published the practical guideline on clinical nutrition and hydration in geria-trics on March 5, 2022. This guideline provides 82 recommendations on clinical nutrition and hydration in geriatrics based on clinical practicability, covering basic problems and general prin-ciples, prevention and treatment of malnutrition/nutri-tional risk, prevention and treatment of specific diseases, as well as prevention and treatment of obesity, along with flow-charts, hoping to be convenient for doctors, nutritionists and nurses to use in clinical practice.
RESUMEN
The American Society for Parenteral and Enteral Nutrition (ASPEN) held the annual academic conference online from March 20 to 23,2021. The current hot topics of clinical nutrition were widely discussed on the conference. The authors briefly report and analyze the hot topics of the conference in order to share and exchange with surgical colleagues.

RESUMEN
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.

RESUMEN
Objective@#To investigate the epidemiological data of nosocomial sepsis of premature infants with gestational age less than 34 weeks and the distribution characteristics of pathogenic bacteria in Shaanxi province.@*Methods@#A retrospective analysis of clinical data of premature infants born with gestational age < 34 weeks born between January 1 and December 30, 2018 in Neonatal Intensive Care Units(NICU) in 4 Grade A Class Three hospitals in Shaanxi province was performed.The high risk factors and pathogenic bacteria were analyzed by using chi-square test and t test for statistical analysis.@*Results@#Totally 823 infants were included in this study, among whom, 73 patients developed nosocomial sepsis, and the incidence was 8.9%.The mean gestational age of the 73 patients with nosocomial sepsis was (30.6±2.2) weeks and mean birth weight was (1 320.3±450.5) g. The rate of invasive ventilator was 23.4%(52/222 cases). The rate of peripherally inserted central catheter (PICC) was 20.1% (61/303 cases). The rate of early antibiotic use was 8.1% (39/481 cases) and breast feeding rate was 9.3% (63/675 cases). The rate of PICC and ventilator use were statistically different between the non-infection group and the infection group(all P<0.05). There were 31 strains of pathogenic bacteria, among which gram-negative bacilli was the most common (22 strains, 70.9%), which mainly were klebsiella pneumoniae strains (15 strains, 48.4%), and 6 strains(19.4%) of Fungus was detected.@*Conclusions@#The incidence of nosocomial sepsis in NICU in Shaanxi province is higher, gram-negative bacilli was the most common pathogenic bacteria, among which, klebsiella pneumoniae was main, it is necessary to strengthen the regular monitoring and analysis of nosocomial infection in NICU in order to reduce the incidence of nosocomial infection and sepsis.
