Objective To investigate the correlation of serum leucine-rich alpha-2 glycoprotein-1(LRG1)and Thiol levels with autoimmune antibodies and renal injury in patients with systemic lupus erythematosus nephritis(SLEN).Methods 80 SLEN patients(SLEN group)and 80 simple SLE patients(non-SLEN group)admitted to the Department of Nephrology at Qingdao Eighth People's Hospital and the Department of Rheumatology and Immunology at Affiliated Hospital of Qingdao University from January 2021 to December 2023 were selected.An enzyme-linked immunosorbent assay(ELISA)was used to detect serum LRG1 levels,while a colorimetric assay was used to detect serum Thiol levels.Pearson/Spearman correlation analysis was used to investigate the correlation between serum LRG1 and Thiol levels,autoimmune antibodies,and renal function indicators in SLEN patients.The diagnostic value of serum LRG1 and Thiol levels in SLEN was analyzed using receiver characteristic curves.Results The serum LRG1(26.00±8.76 μg/ml)and Scr(98.03±49.71μmol/L)in the SLEN group were higher than those in the non-SLEN group(16.71±5.51μg/ml,73.85±33.51μmol/L),and Thiol(80.69±36.90μmol/L)was lower than those in the non-SLEN group(131.49±45.34μmol/L),the differences were statistically significant(t=8.026,3.608,7.772,all P<0.001).Pearson/Spearman correlation analysis showed that serum LRG1 in SLEN patients was positively correlated with anti-double-stranded deoxyribonucleic acid(dsDNA)antibody,anti-complement 1q(C1q)antibody,anti-Smith antibody,serum creatinine(Scr),24-hour urine protein(r=0.226～0.637,all P<0.05),and negatively correlated with estimated glomerular filtration rate(eGFR)(r=-0.633,P<0.05).Serum Thiol was negatively correlated with anti-dsDNA antibodies,anti C1q antibodies,anti-Smith antibodies,Scr and 24-hour urine protein(r=-0.612～-0.256,all P<0.05),and positively correlated with eGFR(r=0.614,P<0.05).The AUC(95%CI)of serum LRG1 combined with Thiol levels for diagnosing of SLEN was 0.907(0.851～0.947),which was higher than that of serum LRG1 and Thiol alone at 0.802(0.731～0.860)and 0.808(0.738～0.866),and the differences were statistically significant(Z=3.450,3.749,all P<0.05).Conclusion Elevated serum LRG1 levels and decreased Thiol levels in SLEN patients were closely related to positive expression of autoimmune antibodies and renal dysfunction.Combined detection of serum LRG1 and Thiols can provide reference for the diagnosis of SLEN.

LIN28 is an RNA binding protein with important roles in early embryo development, stem cell differentiation/reprogramming, tumorigenesis and metabolism. Previous studies have focused mainly on its role in the cytosol where it interacts with Let-7 microRNA precursors or mRNAs, and few have addressed LIN28's role within the nucleus. Here, we show that LIN28 displays dynamic temporal and spatial expression during murine embryo development. Maternal LIN28 expression drops upon exit from the 2-cell stage, and zygotic LIN28 protein is induced at the forming nucleolus during 4-cell to blastocyst stage development, to become dominantly expressed in the cytosol after implantation. In cultured pluripotent stem cells (PSCs), loss of LIN28 led to nucleolar stress and activation of a 2-cell/4-cell-like transcriptional program characterized by the expression of endogenous retrovirus genes. Mechanistically, LIN28 binds to small nucleolar RNAs and rRNA to maintain nucleolar integrity, and its loss leads to nucleolar phase separation defects, ribosomal stress and activation of P53 which in turn binds to and activates 2C transcription factor Dux. LIN28 also resides in a complex containing the nucleolar factor Nucleolin (NCL) and the transcriptional repressor TRIM28, and LIN28 loss leads to reduced occupancy of the NCL/TRIM28 complex on the Dux and rDNA loci, and thus de-repressed Dux and reduced rRNA expression. Lin28 knockout cells with nucleolar stress are more likely to assume a slowly cycling, translationally inert and anabolically inactive state, which is a part of previously unappreciated 2C-like transcriptional program. These findings elucidate novel roles for nucleolar LIN28 in PSCs, and a new mechanism linking 2C program and nucleolar functions in PSCs and early embryo development.

Chronic hepatitis B (CHB) is a major infectious disease which threatens people’s health around the world. Health-related quality of life (HRQoL) has become an important index for evaluating the treatment and prognosis of patients with CHB. Many studies abroad have shown that the HRQoL of patients with CHB is influenced by various factors. Disease severity, clinical symptoms, and low self-efficacy are important influencing factors for patients’ quality of life. Anti-viral therapy, proper physical therapy, or psychological intervention can significantly improve the HRQoL of community CHB patients, and HRQoL is even significantly improved in patients undergoing liver transplantation one year ago. These studies provide valid evidence for antiviral therapy for hepatitis B patients and liver transplantation techniques from the psychological level. At present, there still lacks studies on HRQoL of CHB patients in China. This article summarizes the measurement tools for HRQoL widely used in recent years in China and foreign countries, reviews the research advances in HRQoL in community patients with CHB, and discusses the perspectives for future studies.

OBJECTIVETo investigate the epidemiological characteristics of hand-foot-mouth disease.

METHODSA total of 589 children from Xianju county, Zhejiang province with hand-foot-mouth disease in 2013 were recruited in the study and the diagnosis went through clinical and laboratory confirmation. Attributes that were analyzed included gender, age, month of occurrence, regional distribution and clinical presentation.

RESULTSThe incidence rate of hand-foot-mouth disease in Xianju county for the year was 102.72/100 000, with 12 severe cases but no death. There were clearly more boys than girls, with a male to female ratio of 1.29 :1, which was statistically significant (χ(2) = 14.274, P < 0.001). The vast majority of patients were 0-3 years old, representing 94.74% of the patients. The occurrences were concentrated in the period from April to August and November, with April as the high-incidence season. High incidence areas were the countryside and suburbs, making up 45.50% and 30.73%, respectively, of all cases. Most patients were in preschools or scattered home care environments, accounting for 51.10% and 40.92% , respectively. Clinical presentation was characterized by fever and various kinds of vesicles or papules at the hand, foot, mouth or buttocks.

CONCLUSIONMost of hand-foot-mouth disease cases occur in younger children in areas with inadequate knowledge of hygiene, with seasonal variation.
