Systemic lupus erythematosus is a chronic autoimmune disease.The serology of many patients have changed a few years before the appearance of clinical symptoms,the autoantibody is not just caused by immunologic derangement,but also has relation with tissue lesions.Therefore,it is important to investigate the significance of auto-antibody.This article is aimed at summarizing the relationship between systemic lupus erythematosus and autoantibody.

ObjectiveTo evaluate the role of serum IgM, IgG and IgA anticardiolipin antibody (ACA) isotypes in the diagnosis of systemic lupus erythematosus (SLE), and their association with lupus nephritis (LN) in children.Methods One hundred and sixteen hospitalized SLE pediatric patients were selected between April 2005 and October 2013. The clinical data were collected and analyzed.Results There were 20 males and 96 females among 116 SLE patients. The positive rate of ACA-IgG, ACA-IgM and ACA-IgA was 37.1%, 35.3%, 26.7% respectively, without signiifcant difference between each other (P>0.05). Among 116 SLE patients, 75 cases had LN and 41 cases had no LN. The positive rates of ACA-IgM and ACA-IgA were not sig-niifcantly different between cases with and without LN (P>0.05). Cases with LN (42.7%) had higher ACA-IgG positive rate than cases without LN (22.0%) (P=0.026). The occurrence of LN and the positive rate of ACA isotypes were not signiifcantly different between genders (P>0.05).Conclusions The different isotypes of ACA have the same signiifcance in the diagnosis of SLE. The detection of ACA-IgG helps diagnose the LN complicated with SLE.

Objective To assess the value of cardiac magnetic resonance (CMR) imaging in left ventricular structure and function in patients with end stage renal disease (ESRD).Methods Twenty-five patients with ESRD and 10 healthy subjects underwent CMR.Left ventricular end diastolic volume(EDV),end-diastolic diameter(EDD),end-systolic volume(ESV),end-systolic diameter(ESD),stroke volume(SV),ejection fraction(EF),LVM and interventricular septum (IVS) thickness were measured and compared.The parameters from CMR and 2DTTE were compared.Results The EF in patients with ESRD was significantly lower than that in controls (P＜0.001),while ESV,ESD,IVS and LVM were respectively higher than these in controls (P＜0.05).There was no significant difference (P＞0.05) in ESV between CMR and 2DTTE,but EF of CMR was significantly higher than this of 2DTTE (P＜0.05).There was no significant difference (P =0.296) in left ventricular systolic functional category.Bland-Altman plots showed a good agreement between the two methods.Conclusion CMR is a helpful tool to assess left ventricular structure and function in patients with ESRD.

Objective To investigate the diagnostic value Tamm-Horsfall protein(THP)and osteopontin(OPN)in serum and 24-hour urine for urolithiasis.Methods A total of 101 patients with urolithiasis who underwent flexible ureteroscopy lithotripsy at the Urology Department of Civil Aviation General Hospital from April 2020 to March 2023 were included as the stone group,and 50 healthy individuals were enrolled as the control group.The samples of serum and 24-hour urine samples were collected from both the groups,and the levels of THP and OPN were measured using enzyme-linked immunosorbent assay(ELISA).Logistic regression analysis was performed to evaluate the association between each biomarker and urolithiasis,and receiver operating characteristic(ROC)curves were plotted to assess their diagnostic value.Results The stone group showed significantly lower THP levels(20.13[13.12,26.03]mg/d)and OPN levels(51.24[36.72,101.37]μg/d)in 24-hour urine,and THP levels(182.01[160.91,209.20]ng/mL)and OPN lev-els(18.76[15.72,22.48]ng/mL)in serum compared to the control group(all the P＜0.001).Binary Logistic regression analysis re-vealed that THP(OR=0.736,95％CI:0.606-0.895),OPN(OR=0.975,95％CI:0.958-0.993)and citrate(OR=0.067,95％CI:0.012-0.376)in 24-hour urine,and THP(OR=0.946,95％CI:0.908-0.986)and OPN(OR=0.896,95％CI:0.803-0.999)in ser-um were the protective factors for urolithiasis,while calcium level(OR=2.125,95％CI:1.243-3.633)24-hour urine was a risk factor(all the P＜0.05).ROC curve analysis showed that the areas under the curve(AUCROC)for the individual diagnosis of urolithiasis were 0.846,0.809,0.786,0.823,0.748,and 0.755 for the above six biomarkers,respectively.The AUCROC for the combined diagnosis u-sing THP+OPN in serum,THP+OPN in 24-hour urine and all the six biomarkers were 0.882,0.920 and 0.984,respectively,indica-ting better diagnostic performance.Conclusion The combined detection of the THP and OPN levels in serum and 24-hour urine may have good diagnostic value for urolithiasis and serve as potential diagnostic biomarkers.

The aim of this study is to explore the protective mechanism of Jiedu Tongluo Tiaogan decoction(JTTD)on islet cells of type 2 diabetic SD rats based on autophagy regulation.8-week-old SD male mice were fed with high-fat diet for 4 weeks and then induced with a single intraper-itoneal injection of streptozotocin 40 mg/kg.The Chinese medicine group was given the low(1.5 g·kg-1·d-1),medium(4.5 g·kg-1·d-1)and high(13.5 g·kg-1·d-1)doses of JTTD,and the western medicine group was given metformin hydrochloride(0.15 g·kg-1·d-1).Fasting blood glucose(FBG),glycated serum protein(GSP),triglycerides(TG),cholesterol(CHO),high-densi-ty lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),free fat(FFA)were measured.Moreover,the fasting serum insulin was determined by ELISA method and insulin resistance index(HOMA-IR)was calculated,glucose tolerance test was performed.The pancreatic tissues of SD mice were stained with HE,and the expression of Beclin-1 and LC3 were checked by immunohistochemistry,the expression of Beclin-1,LC3 and P62 was determined by Western blot,the expression of Beclin-1 and LC3RNA was determined by RT-PCR.The results showed that both the JTTD group and metformin hydrochloride group had better hypoglycemic and lipid-lowering effects(P＜0.05,P＜0.01).HE staining of pancreatic tissues showed that disorganized structure,unclear boundary,irregular arrangement,less cytoplasm,and lighter cytoplasmic staining or vacuo-lation in the islets in the JTTD group and metformin hydrochloride group were improved.In terms of autophagy regulation,immunohistochemistry,Western blot and RT-PCR,compared with the model group,the expression of Beclin-1 and LC3 mRNA was significantly increased(P＜0.01)and the level of p62 protein was decreased(P＜0.05,P＜0.01)in the JTTD group and metformin hydrochloride group.In conclusion,the JTTD can alleviate the trend of weight loss and improve ex-cessive drinking effectively in type 2 diabetic mellitus SD mice,as well as have better effects on im-proving glucose and lipid metabolism,moreover,it can alleviate the damage of pancreatic his-topathological structure and protect islet cells,which may be achieved by regulating the level of au-tophagy.

Lung cancer is one of the most common malignancies with the highest incidence rate and mortality rate worldwide, and non-small cell lung cancer (NSCLC) accounts for about 85%. Only 5% NSCLC patients are anaplastic lymphoma kinase (ALK) rearrangement positive NSCLC, but the prognosis of these patients is poor, and treatment is urgent. Ensartinib (X-396), a next-generation ALK tyrosine kinase inhibitor (ALK-TKI), has shown greater potency on inhibiting ALK activity and controlling brain metastases than crizotinib, which is indicated for the treatment of crizotinib-resistant, ALK-positive NSCLC patients. Several phase I to III clinical trials included both healthy volunteers and NSCLC patients have been conducted both in China and abroad. In this review, we briefly summarized the results of these trials, and preliminary efficacy, safety, pharmacology and pharmacokinetics/pharmacodynamics of ensartinib were discussed.
