Objective To find out a more rational pathological classification criteria for renal injury in patients with type 2 diabetes mellitus. Methods The renal clinicopathological features of forty-nine type 2 diabetic patients with maeroalbuminuria were collected and were compared retrospectively. The patients without diabetic renal disease were excluded. According to the pathological features, the patients were divided into two groups: typical diabetic glomerulopathy (DG) and atypical diabetes-related renal disease (ADRD). Results The renal biopsy revealed DG accounted for 59.2% of the patients, while the remaining 40.8% presented atypical renal injury defined as ADRD. In DG group, volume fraction of mesangium per glomerulus, glomerular basement membrane width, atrophic tubules index, intersititium injury index and prevalence of hyalinization of renal arteriole were higher; podocyte density per glomerulus was lower; duration of type 2 diabetes was longer; the level of fast blood glucose, systolic blood pressure, mean arterial pressure, proteinuria and prevalence of diabetic retinopathy (DR) were higher; glomerular filtration rate (GFR) was lower. In ADRD group, body mass index and prevalence of obesity were higher; dyslipidemia was more severe. GFR was negatively correlated with glomerular global sclerosis rate in both DG and ADRD group. Proteinuria was positively correlated with volume fraction of mesangium per glomerulus in DG. No correlation between proteinuria and pathological features was found in ADRD. DR (94.8%) and duration of type 2 diabetes over five years (90.7%) had high negative predictive value for DG. Conclusions Renal injuries in type 2 diabetes patients are heterogeneous. ADRD is an atypical renal injury in type 2 diabetes patients whieh is different from DG. DR and duration of diabetes are more helpful in predicting DG separating from ADRD.

Objective To study the pathologic pattern and clinical feature of type 2 diabetes mellitus complicated with chronic kidney diseases (CKD). Methods Clinicopathological features of 155 type 2 diabetic patients complicated with CKD were collected and analyzed retrospectively. The patients were divided into four groups: typical diabetic glomerulopathy (DG),atypical diabetes-related renal disease (ADRD), non-diabetic renal diseases (NDRD) and DG complicated with NDRD. Results Renal biopsies revealed DG accounted for 18.7% of the patients, ADRD accounted for 12.9%, NDRD accounted for 60.0%, and DG complicated with NDRD accounted for 8.4%. In DG group, duration of type 2 diabetes was longer;the level of fast blood glucose, systolic blood pressure, mean arterial pressure and prevalence of diabetic retinopathy (DR) were higher;proteinuria was heavier and evaluated glomerular filtration rate (eGFR) was lower. In ADRD group, body mass index and prevalence of obesity were higher;dyslipidemia was more severe. Gross hematuria and acute renal insufficiency could be only found in NDRD group.Without DR, duration of diabetes under 5 years, gross hematuria, acute renal insufficiency,evidences of autoimmune diseases and proteinuria≥3.5 g/24 h but eGFR ≥60 ml/min were specific valuable predictors for NDRD. Conclusions Renal injuries in type 2 diabetic patients are structural heterogeneous, in which NDRD is more common and is different from ADRD and DG.Renal biopsy should be considered when type 2 diabetic patients complicated with CKD present at least one characteristic as follows: duration of diabetes under 5 years, without DR, history of gross hematuria, acute decrease of renal function, evidences of autoimmune diseases and proteinuria ≥ 3.5 g/24 h but eGFR ≥ 60 ml/min.

Objective To explore the level of Th2 type cytokines including IL-4, IL-10 and IL-13, and the immunoreg-ulation of cytokines in patients with neurocysticercosis. Methods Lymphocytes in patients with neurocysticercosis were separated from the blood sample with density gradient centrifugation and the total RNA was extracted by guanidine isothiocynate method. cDNA was synthesized by reversed transcription reaction. The target gene was then amplified by PCR. The PCR products were analyzed by electrophoresis. Results Results of RT-PCR showed that cytokines mRNA in lymphocytes of peripheral blcod were detected in 27 patients with neurocysticercosis but not in the other 3 cases. Among the positive cases, mRNA of IL-4, IL-10 and IL-13 was detected in 16, 17 and 14 cases respectively and mRNA of IL-4, IL-10 and/or IL-13 was detected in all the 27 cases. In the detection of lymphocytes in peripheral blcod of 10 healthy subjects, expression of IL-4 and IL-10 was found in only one case at low level. Conclusion The study revealed that Th2 associated cytokines were expressed at high level and the humoral immunocompetence was relatively strong in patients with neurocysticercosis.

OBJECTIVETo explore the clinical characteristics and genetic mutations in two children with Omenn syndromes.
METHODSPeripheral venous blood samples were collected from 2 children suspected with severe combined immunodeficiency (SCID) and their family members. The samples were subjected to RAG1 and RAG2 gene sequencing and TCR Vβ subclone analysis.
RESULTSBoth patients had recurrent infections, erythroderma rashes and alopecia baldness. One patient has fit with immunophenotype T-B-NK+, while another was consistent with typical Omenn syndrome combined with T+B-NK+ immunophenotype, IgE and eosinophil increase. Both children have carried compound heterozygous mutations of the RAG1 gene. The first patient carried c.1328 G>A (p.R443K) and c.2486-2490delGGAAA (p.R829fsX869) mutations, both were of de novel type. The second patient has carried c.1209C>T (p.R403W) and c.2892delT (p.ASN964LYSfs*14), with c.2892delT (p.ASN964LYSfs*14) being a de novel mutation. The parents of both patients were heterozygous carriers. The same mutations were not found in 100 healthy children. Both patients' 24 TCR Vβ subfamilies have presented monoclonal or oligoclonal peaks, with TCR Vβ polymorphism being severely disrupted.
CONCLUSIONThree novel mutations have been identified in two children with Omenn syndrome, which featured early onset and rapid progression. Early recognition of the disease and prompt treatment may reduce the mortality.
