Objective:To analyze the clinical characteristics, etiological composition, imaging features, and prognosis of adrenal metastases.Methods:This study is a retrospective case series that included 96 patients with pathologically confirmed adrenal metastases who were treated at West China Hospital, Sichuan University, from 2007 to 2017. Clinical features such as sex, age, tumor size, biochemical tests, imaging characteristics, postoperative pathology, treatment methods, and prognosis were collected and analyzed. The prognosis of patients and its influencing factors were analyzed by Kaplan-Meier survival curve and single-factor Cox risk proportional model.Results:Among the 96 included patients, 64 were male and 32 were female, with a median age of 60 years. There were 89 cases of unilateral adrenal metastases, five cases of bilateral metastases, and two cases with unspecified laterality. The median diameter of the metastases was 3.5 cm×2.9 cm, with an average CT value of 31 HU. Thirty-four cases of adrenal hormones were evaluated, and no abnormality was found.The primary tumor sites were as follows: lung ( n=36), kidney ( n=19), liver ( n=12), pancreas ( n=7), rectum ( n=3), stomach ( n=2), and one case each of tumor in the esophagus, skin, thyroid, left maxillary muscle, breast, bladder, cervix, chest wall, and gastrointestinal tract. There were three cases with unknown primary tumors. The most common pathological type was lung adenocarcinoma (20.8%, 20/96), followed by hepatocellular carcinoma (9.4%, 9/96) and high-grade invasive urothelial carcinoma of the kidney (8.3%, 8/96). Thirty-nine cases were diagnosed concurrently with the primary tumor, while 37 cases were diagnosed after the primary tumor, with a median interval of 15 months (range: 2-144 months). There was no significant correlation between the death risk of adrenal metastatic tumor patients and gender, age, and the size of the metastatic tumor (all P>0.05). There were 4 patients with radiotherapy and chemotherapy alone, 19 patients with surgery alone, and 6 patients with combined radiotherapy and chemotherapy. The median overall survival was 1, 3, and 7 years, respectively. Conclusions:Adrenal metastases were mostly diagnosed at the same time as the primary tumor or within 15 months after the diagnosis of the primary tumor. Unilateral metastasis is common. The lungs are the most common primary lesion, followed by the kidney and liver. CT is the preferred method for the diagnosis of adrenal metastases, and the plain CT value is more than 30 HU. The overall prognosis of adrenal metastases is poor. The prognosis was better for patients who underwent surgery combined with radiotherapy and chemotherapy than those who received only surgery or radiotherapy and chemotherapy alone.

Amplifying "eat me signal" during tumor immunogenic cell death (ICD) cascade is crucial for tumor immunotherapy. Inspired by the indispensable role of adenosine triphosphate (ATP, a necessary "eat me signal" for ICD), a versatile ICD amplifier was developed for chemotherapy-sensitized immunotherapy. Doxorubicin (DOX), ATP and ferrous ions (Fe²⁺) were co-assembled into nanosized amplifier (ADO-Fe) through π‒π stacking and coordination effect. Meanwhile, phenylboric acid-polyethylene glycol-phenylboric acid (PBA-PEG-PBA) was modified on the surface of ADO-Fe (denoted as PADO-Fe) by the virtue of d-ribose unit of ATP. PADO-Fe could display active targetability against tumor cells via sialic acid/PBA interaction. In acidic microenvironment, PBA-PEG-PBA would dissociate from amplifier. Moreover, high H₂O₂ concentration would induce hydroxyl radical (·OH) and oxygen (O₂) generation through Fenton reaction by Fe²⁺. DOX and ATP would be released from the amplifier, which could induce ICD effect and "ICD adjuvant" to amplify this process. Together with programmed death ligands 1 (PD-L1) checkpoint blockade immunotherapy, PADO-Fe could not only activate immune response against primary tumor, but also strong abscopal effect against distant tumor. Our simple and multifunctional ICD amplifier opens a new window for enhancing ICD effect and immune checkpoint blockade therapy.

Coronavirus disease 2019(COVID-19),which is caused by SARS-CoV-2,varies with regard to symptoms and mortality rates among populations.Humoral immunity plays critical roles in SARS-CoV-2 infection and recovery from COVID-19.However,differences in immune responses and clinical features among COVID-19 patients remain largely unknown.Here,we report a database for COVID-19-specific IgG/IgM immune responses and clinical parameters(named COVID-ONE-hi).COVID-ONE-hi is based on the data that contain the IgG/IgM responses to 24 full-length/truncated proteins corresponding to 20 of 28 known SARS-CoV-2 proteins and 199 spike protein peptides against 2360 serum samples collected from 783 COVID-19 patients.In addition,96 clinical parameters for the 2360 serum samples and basic information for the 783 patients are integrated into the database.Furthermore,COVID-ONE-hi provides a dashboard for defining samples and a one-click analysis pipeline for a single group or paired groups.A set of samples of interest is easily defined by adjusting the scale bars of a variety of parameters.After the"START"button is clicked,one can readily obtain a comprehensive analysis report for further interpretation.COVID-ONE-hi is freely available at www.COVID-ONE.cn.

A 47-year-old female patient presented nausea and vomiting for half a year and elevated serum creatinine for 3 days. Proximal renal tubular acidosis (RTA) complicated with anemiawas confirmed after admission. Secondary factors, such as autoimmune disease, drugs, poison, monoclonal gammopathy, were excluded. Renal biopsy revealed acute interstitial nephritis. The patient was administrated with daily prednisone 50 mg, sodium bicarbonate 4 g, 3 times per day, erythropoietin 3 000 U, 2 times per week, combined with potassium, calcium, and calcitriol tablets. Serum creatinine reduced to 90 μmol/L. However nausea and vomiting deteriorated with lactic acidosis. Bone marrow biopsy indicated the diagnosis of non-Hodgkin lymphoma, therefore the patient was treated with chemotherapy. Although metabolic acidosis improved gradually after chemotherapy, severe pneumocystis carinii pneumonia developed two weeks later. The patient refused further treatment and was discharged.

The GATA transcription factor family is a type of transcription regulatory factors containing zinc finger structure,in which GATA4,GATA5 and GATA6 play a key role in the process of heart development and functional maturity.A large number of studies have confirmed that the GATA transcription factor family is not only involved in the the heart development,but also its mutations are related to the occurrence of human congenital heart diseases (CHD).This article mainly reviews the relationship between GATA family with heart development,and the relationship between GATA family gene mutation with congenital heart diseases.

A 22-year-old manpresented as a refractory nephrotic syndrome with edema and proteinuria for more than one year. Physical examination revealed facial steatadenomas and periungual fibromas. Images were characterized by hamartomatous lesions in multiple organs, including the central nervous system, heart, lungs, liver, and kidneys. Gene tests verified TSC2 mutation and confirmed the diagnosis of tuberous sclerosis complex. The APOL1 mutation was positive in this patient, which indicated the possibility of steroid-resistant focal segmental glomerulonephritis. Thus, he was treated with sirolimus. Renal angiomyolipoma was shrunk, but proteinuria was not relieved (24h unine protein>10 g) and eventually led into renal insufficiency. Nondialytic therapy was initiated consequently. Losartan 50 mg/d was used to control proteinuria under the close watch of serum creatinine. A recent phone call on October 2018 failed to reachthe patient. Therefore, the follow-up information was not updated.

Objective To investigate the clinical and pathological features of patients with a combination of Sjogren's syndrome (SS) and antineutrophil cytoplasmic antibody (ANCA) associated vasculitis with renal involvement.Methods By searching the Peking Union Medical College Hospital medical database and literature between January 1990 and June 2017,patients had a combination of SS and ANCA associated vasculitis with renal involvement were included.Data of clinical information,autoimmune antibodies,renal manifestations and renal pathology were retrieved and analyzed.Results Eighteen patients were enrolled:4 from our hospital and 14 from literature.SS was diagnosed no later than ANCA associated vasculitis in all the patients,among which 83.3％(15/18) of patients had extra-glandular and extra-renal organs involved.All the patients were tested positive for myeloperoxidase (MPO)-ANCA,and only two were protein 3 (PR3)-ANCA positive concurrently.The positivity rates of antinuclear antibody (ANA),rheumatoid factor (RF),anti-SSA antibody,and anti-SSB antibody were 83.3％(15/18),55.6％(10/18),77.8％(14/18),and 38.9％(7/18),respectively.The renal manifestations were characterized by renal insufficiency with a median serum creatinine of 174 μmol/L,hematuria,moderate proteinuria with a median 24 hour urine protein of 1.70 g,and necrotizing vasculitis with oligo-immune complex and varying degrees of interstitial damage in pathology.Conclusions A combination of Sjogren's syndrome and ANCA associated vasculitis with renal involvement is rare in clinical setting,and almost all of the patients are MPO-ANCA positive,with high probability of ANA positivity and extra-glandular involvement.Physicians should beware of ANCA associated glomerulonephritis in SS patients with inexplicable renal dysfunction and renal biopsy should be carried out in time.

Objectives To analyze the spectrum of renal diseases associated with monoclonal gammopathy and unrelated renal diseases.Methods Hospitalized patients in Peking Union Medical College Hospital who underwent renal biopsy between January,2013 and December,2015.They had monoclonal gammopathy on serum protein electrophoresis (SPE),serum immunofixation electrophoresis (IFE),urine IFE and/or serum free light chain (FLC).64 patients met the inclusion criteria and were classified as monoclonal gammopathy of renal significance (MGRS) (n=36),monoclonal gammopathy of undetermined significance (MGUS) (n=17) and hematologic malignancy (n=11).Results Renal lesions in MGRS subgroup included light chain amyloidosis (n=28,77.8％),light chain deposition disease (n=7,19.4％),and fibrillary glomerulopathy (n=l,2.8％).eGFR in light chain amyloidosis subgroup differed significantly,compared with light chain deposition disease [eGFR 93 ml· min-1 · (1.73m2)-1 vs 28 ml· min-1 · (1.73 m2) 1,P ＜ 0.01],as well as HTN incidence (35.7％ vs 100.0％,P ＜ 0.01).Renal diseases in MGUS subgroup included membranous nephropathy (n=10,58.8％),focal segmental glomerulosclerosis (n=3,17.6％),diabetic glomerulopathy (n=l,5.9％),Henoch-Schonlein purpura nephritis (n=l,5.9％),anti-glomerular basement membrane disease concurrent with membranous nephropathy (n=l,5.9％) and glomerulomegaly (n=l,5.9％).Various renal lesions related/unrelated to hematologic malignancy were seen in third subgroup,including light chain cast nephropathy (n=3,27.3％),tubulo-interstitial lesions (n=2,18.2％),light chain amyloidosis (n=1,9.1％),light chain deposition disease(n=1,9.1％),IgA nephropathy (n=1,9.1％),mesangial proliferative glomerulonephritis (n=l,9.1％),endocapillary proliferative glomerulonephritis (n=1,9.1％) and acute tubular necrosis (n=1,9.1％).Positive rates of SPE,serun IFE and urine IFE in MGRS subgroup were 40.6％,52.8％ and 69.4％,respectively.Positive rates of SPE,serum IFE and urine IFE in MGUS subgroup were 68.8％,100.0％ and 37.5％,respectively.Positive rates of SPE,serum IFE and urine IFE in hematologic malignancy subgroup were 54.5％,72.7％ and 81.8％ respectively.MGRS and MGUS subgroups differed significantly in positive rate of serum IFE (P ＜ 0.001).Abnormal rates of serum FLC ratio in above three subgroups were 83.3％,17.6％ and 90.9％,respectively,with that in MGUS group being significantly lower than the rates in other two groups (P ＜ 0.001,respectively).Conclusions The significance of monoclonal gammopathy in patients with renal disease should be evaluated by other clinical data,as well as renal pathology.

Objective To assess the predictive value of Berden classification in ANCA associated glomerulonephritis.Methods Patients with confirmed ANCA associated glomerulonephritis were included,by retrieving the medical database in Peking Union Medical College Hospital from January 2000 to May 2015.Their detailed information during hospitalization and follow-up was recorded.The patients were divided into four categories based on Berden classification.The differences in clinical characters,renal function and response for treatment were compared.Results Among the 88 patients with ANCA-associated glomerulonephritis,19 (21.6％),21 (23.9％),32 (36.4％)and 16 (18.2％) patients were classified as focal,mixed,crescentic and sclerotic category.22 patients developed ESRD,and 19 patients died during follow up (1 patient developed ESRD before died).The mean estimated glomerular filtration rate (eGFR) at baseline was 68.04,25.45,30.04,15.16 ml·min-1·(1.73 m2)-1 (P ＜ 0.05) in focal,crescentic,mixed and sclerotic category,respectively.During follow-up period,focal category always had the best renal function,while sclerotic category had the worst renal function.Crescentic category and mixed category were similar and in the middle.Remission rate at 6m was 62.5％,73.7％,57.5％,30.8％(P ＞ 0.05).And crescentic category had the greatest improvement in eGFR at 6m.Conclusions Focal category had relatively preserved renal function and favorable renal outcome,while the sclerotic category had the worst renal outcome.Crescentic and mixed category had an intermediate outcome.We support the use of the Berden classification in predicting the renal prognosis of patients with ANCA associated glomerulonephritis.

Objective To investigate the clinicopathological characteristics of IgAN patients with massive proteinuria,as well as their treatment response to glucocorticoids and long-term prognosis.Methods Clinical and pathological parameters were collected in patients diagnosed with IgA nephropathy in our hospital from Jan 2003 to Oct 2015.Patients were followed up for at least six months under the treatment with full dosage of glucocorticoids.Responses of patients with and without nephrotic syndrome were compared.Results A total of 156 patients were enrolled for the analysis (86 patients in the nephropathic proteinuria group,and 70 patients in the nephrotic syndrome group).Patients presented with nephrotic syndrome showed higher proportion of IgM deposition in renal slides.There exited no difference in treatment response to glucocorticoids between the two groups.Patients with full or partial remission showed a better prognosis by Kaplan-Meier analysis than no remission group (P ＜ 0.001).The ratio of segmental sclerosis was negatively correlated with treatment response to glucocorticoids by multiple linear regression (3 value=-0.330,P ＜ 0.001).Multivariate Cox regression model showed that glomerular density (HR=0.45,P=0.02) and eGFR (HR=0.95,P=0.001)were independent influential factors for renal survival.Conclusions Patients presented with nephrotic syndrome show higher proportion of IgM deposition in renal slides.Patients in remission after treatment with 6-month glucocorticoids present a better prognosis than no remission patients,and glomerular density as well as eGFR are independent influential factors for renal survival.
