Steroid-resistant nephrotic syndrome (SRNS) is the second cause of chronic kidney disease in children. The SRNS has high risk of rapid progression to end-stage renal disease. With the advancement of high-throughput sequencing technology, more than 70 monogenic mutation having the Mendelian inheritance patterns are identified to be associated with SRNS. Most of these genes are involved in podocyte function. Accurate diagnosis of monogenic mutation in SRNS patients helps with guiding clinical treatment protocols and genetic counseling, avoiding the excessive use of steroids/immunosuppressive therapy, and opening up possibilities for targeted therapies in SRNS patients. In this article, our research team summarizes and generalizes the molecular mechanisms, genetic testing, and specific treatment for the major types of monogenic mutations associated with SRNS.

Mucin-type O-glycosylation is one of the most common post-translational modifications in proteins,capable of altering protein conformation and biological functions.It plays a crucial role in biological processes such as cell signaling,cell adhesion,and immune responses.Polypeptide N-acetylgalactosaminyltransferase 3(GALNT3),as the initiating enzyme of mucin-type O-glycosylation,is of paramount importance in maintaining the homeostasis of human cells and tissues.Dysfunction of GALNT3 has been found to play a role in various diseases,such as calcium-phosphorus metabolism disorders and atherosclerosis.Additionally,GALNT3 is abnormally expressed in several types of tumors,including colorectal cancer,lung cancer,and ovarian cancer.Its expression is associated with the clinical pathological features of patients and poor prognosis,making it a potential biomarker for early tumor diagnosis and prognosis evaluation.Further research shows that GALNT3 can both regulate glycosylation levels to reduce adhesion between tumor cells and activate multiple metabolism-related pathways,promoting tumor cell invasion and metastasis.This review summarizes the role of GALNT3 in the development of malignant tumors and discusses the prospects and challenges of developing anti-tumor drugs targeting GALNT3.

Neurodegenerative diseases are a type of disease characterized by specific types of neuronal loss and progressive progression,mainly represented by Alzheimer's disease and Parkinson's disease.This type of disease,due to its intractable and irreversible symptoms,brings great physical and psychological burden to patients,which is seriously disturbing their normal life.In terms of treatment,there is currently no specific treatment for Alzheimer's disease in clinical practice,and first-line treatment drugs for Parkinson's disease also have great limitations.In traditional Chinese medicine,kidney governs bone,generates marrow,and connects to the brain.In clinical evidence typing,premature aging,fatigue and forgetfulness,and tremor of limbs caused by kidney deficiency and medullary reduction are considered to be the main pathologies of these diseases.Di-Huang-Yin-Zi decoction which is derived from the"General Records of Holy Universal Relief",is recorded as a good formula for nourishing kidney yin and filling kidney yang.Clinical data shows that this formula has significant therapeutic effects in treating neurodegenerative diseases caused by kidney essence deficiency.Modern research results indicate that its mechanism of action involves inhibiting inflammatory reactions,regulating mitochondrial autophagy,reversing The hypothalamic-pituitary-adrenal axis abnormalities,and neuroprotection.The main effective ingredients in this formula include loganin,echinarin,and schisandrin A.This article aims to summarize and analyze the clinical efficacy,mechanism of action,and active ingredients of Di-Huang-Yin-Zi decoction in the treatment of Alzheimer's and Parkinson's disease in recent years,in order to clarify the research status of Di-Huang-Yin-Zi decoction in the neurodegenerative disease and provide reference for further research.

Objective:To investigate the effects of different feeding formulas on the feeding and growth and metabolism of premature infants in the early postnatal period.Methods:Eligible premature infants with the gestational age of ≤ 34 weeks hospitalized from March 2023 to March 2024 were selected as per inclusion criteria, excluding those with congenital metabolic diseases, severe congenital heart disease and developmental malformations of digestive tract. According to the feeding formulas within 2 weeks after birth, premature infants were divided into three groups, namely donor human milk (DHM) group, preterm formula (PF) group and extensively hydrolyzed formula (eHF) group. The characteristics of premature infants, perinatal condition, feeding formulas, milk intake on the 7th and 14th day, the time to the daily milk intake of 120ml/kg and 150ml/kg respectively, the time on parenteral nutrition, the length of hospitalization, feeding intolerance, cholestasis, extrauterine growth retardation and biochemical metabolic indexes at 7 days, 14 days and discharge were collected. The differences of feeding and biochemical metabolic parameters were compared across the three groups.Results:A total of 108 cases were enrolled ,of whom 39 were in DHM group, 37 in PF group and 32 in eHF group. There was no significant difference in gestational age, birth weight, head circumference and maternal complications across the three groups. The milk intake in the DHM group was (50.7±29.1) ml/(kg·d) on the 7th day, compared with (34.2±27.3) ml/(kg·d) in PF group ( P=0.031), and (103.1±36.7) ml/(kg·d) on the 14th day, compared with (73.9±39.2) ml/(kg·d) in the PF group. Compared with the PF group, the DHM group reached the daily milk intake of 120 ml/(kg·d) earlier [(18.5±10.4) days vs. (24.1±10.3) days, P=0.020], had shorter duration of parenteral nutrition [(17.9±10.9) days vs. (23.2±11.2) days, P=0.042], and lower incidence of feeding intolerance (28.2% vs. 48.6%). The length of hospitalization in DHM group was shorter than that in PF group [(33.8±15.5) days vs. (37.8±17.6) days], but there was no significant difference ( P>0.05). There was no significant difference between the DHM group and the eHF group in terms of the milk intake on the 7th and 14th day, the time to the daily milk intake of 120 ml/(kg·d), the time on parenteral nutrition, the length of hospitalization and feeding intolerance. At 1 and 2 weeks after birth, alkaline phosphatase in DHM group was higher than that in PF group and eHF group ( P<0.05), but there was no significant difference in biochemical nutritional metabolism parameters (hemoglobin, urea nitrogen, albumin, prealbumin, alkaline phosphatase and total bile acid) across the three groups at discharge( P>0.05). Conclusion:Early use of DHM in premature infants is better tolerated than PF and can help achieve complete enteral nutrition earlier and shorten the use of parenteral nutrition, while not affecting the growth and development of premature infants.

Objective To construct a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer and to evaluate its efficacy.Methods Through literature review and Delphi expert correspondence,a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer was constructed.By the convenience sampling method,200 consecutive children who received chemotherapy in the neurosurgery department of a tertiary children's hospital in Zhejiang province from February 1 to October 31,2023 were included as the application subjects,with 100 cases in an experimental group and 100 cases in a control group.The experimental group applied the non-drug intervention program of acute chemotherapy-related nausea and vomiting in children with cancer,and the routine measures were applied in the control group.The incidence of nausea and vomiting,severity of vomiting,compliance rate of normal sleep duration and incidence of negative emotions were compared between the 2 groups.Results The recovery rate of the valid questionnaire in 2 rounds of expert letter inquiry was 100％,and the expert authority coefficient was 0.836.The Kendall harmony coefficients were 0.471 and 0.820(P＜0.001),and the final non-drug intervention program for pediatric acute chemotherapy-related nausea and vomiting included 5 primary,14 secondary and 18 tertiary items.The results showed that the incidence of nausea,vomiting and negative emotions in the experimental group were lower than that in the control group,with statistically significant differences(P＜0.05).The severity of vomiting was less than it in the control group,with statistically significant difference(P＜0.05).The standard rate of normal sleep time was higher than that of the control group,and the difference was statistically significant(all P＜0.05).Conclusion The non-drug intervention program of chemotherapy-related nausea and vomiting in children is scientific and feasible,and the implementation of the program can reduce the incidence of nausea,vomiting and negative emotions,reduce the severity of vomiting,and improve the standard rate of normal bedtime in children.

Objective To explore a method for assessing the irregular small opacities profusion associated with occupational pneumoconiosis in chest computed tomography (CT). Methods A total of 20 occupational pneumoconiosis patients whose primary manifestation was irregular small opacities on chest digital radiography (DR) were collected as the research subjects using a retrospective study method. Comparative analysis was performed between chest DR and five mm coronal multi-planar reconstruction (MPR) of chest CT images to identify the causes of irregular small opacities. An evaluation method for the profusion of associated images of irregular small opacities in chest CT was established using technique for order preference by similarity to ideal solution-analytic hierarchy process (TOPSIS-AHP), and the results were compared against GBZ 70-2015 Diagnosis of Occupational Pneumoconiosis. Results The abnormal image distribution on the five mm coronal chest CT MPR images of the 20 patients was as follows: three cases of high-density small circular opacities, seven cases of low-density circular small opacities, six cases of diffuse low-density ground-glass opacities (GGO), four cases of reticular opacities, three cases of plate-like GGO, three cases of honeycomb opacities, and four cases of increasing lung texture. The CT values of abnormal images, from high to low were: honeycomb opacities > plate-like GGO > low-density circular small opacities > diffuse low-density GGO (all P<0.05). The consistency test results indicated that the evaluation method for the profusion of associated images of irregular small opacities in chest CT showed high level of agreement with the profusion determination criteria outlined in GBZ 70-2015 Diagnosis of Occupational Pneumoconiosis (Kappa=0.78). Conclusion Irregular small opacities observed on chest DR are formed by the superposition of multiple images of abnormal pulmonary fibrosis in patients with occupational pneumoconiosis. TOPSIS-AHP can be used to establish an evaluation method of the profusion of associated image of irregular small opacity in chest CT.

Objective? To explore the effects of interpregancy interval (IPI) on pregnancy outcomes in multiparas with vaginal delivery and to provide a scientific reference for preconception counseling and clinical guidance for women who planned to bear another child. Methods? All the multiparas who labored via vaginal delivery in Peking University Third Hospital between January and December 2016 were selected in this retrospective analysis. The multiparas were divided into three groups based on their IPI. The IPI of the first group was 0-35 months (n=134); The IPI of the second group was 36-71 months (n=274); and the IPI of the third group was≥72 months(n=256). The relationship between IPI and pregnancy complications, comorbidities, labor time, hemorrhage and perinatal outcome was analyzed. SPSS 22.0 was used for statistical analysis. Results? Premature rupture of membranes (PROM) was found in 18 multiparas in the first group, 37 in the second group and 58 in the third group; uterine fibroid was found in 7 multiparas in the first group, 17 in the second group and 31 in the third group; there was statistically significant difference in PROM and the incidence rate of uterine fibroid between the groups with different IPI (χ2=9.379,8.143;P＜0.05); when confounding factors such as the mothers' age were adjusted, the risk of PROM and uterine fibroid continued to rise since the 72nd month of IPI (OR=1.888,2.519;P＜0.05). Conclusions? Longer IPI is associated with the increase in the risk of PROM and uterine fibroid. Pre-pregnancy and pregnancy education should be enhanced to ensure maternal and child health according to the characteristics of multiparas with longer IPI.

Zn lactate and SnF₂ were used as active compounds in the dentifrice. Here, their anti-biofilm effects were evaluated on Pseudomonas aeruginosa, Acinetobacter baumannii and Streptococcus mutans. The biofilm prevention/dispersal assay of P. aeruginosa PAO1 demonstrated that Zn lactate and SnF₂ can inhibit biofilm formation independently or by combined treatment. Zn lactate disrupted extracellular polysaccharides matrix formation and SnF₂ reduced the biomass of biofilm. Most importantly, the combination of Zn lactate and SnF₂ thoroughly abolished the biofilm formation of all three strains.
