In recent years, the diagnosis of idiopathic membranous nephropathy (IMN) has been more and more important with the rapid growth rate on incidence in China.Previous diagnosis of IMN depends on renal biopsy, a gold standard, but a high risk of traumatic examination.The detection of serum PLA2R antibody and THSD7A antibody to assist in the diagnosis of is not only fast, sensitive, simple and noninvasive, but also can reflect the immune status in real time.Compared with the traditional proteinuria severity based therapeutic efficacy evaluation, that is more effective and agile to monitor the disease condition, reflect the treatment effects and predict the prognosis better.Therefore, it should be vigorously promoted.

Chlamydia psittaci is a causative agent of psittacosis,which can infect a wide range of hosts including birds and humans.However,information regarding C.psittaci infection in pigeons is scarce.In the present study,a total of 399 fecal samples from pigeons were collected from Jilin Province,northeastern China,between March and May 2015,and examined by nested PCR amplification of outer membrane protein A (ompA) gene.The overall Chlamydiosis prevalence was 5.01％ (21/399),with 3.19％ in Changchun City and 9.40％ in Jilin City.Furthermore,breed was the major risk factor associated with Chlamydia infection in pigeon,boiler pigeons had a prevalence of 7.49％,whereas no C.psittaci was detected in racing pigeons.Sequence analysis of the ompA gene revealed that all the identified isolates represented C.psittaci genotype B.Our results firstly indicated the presence of zoonotic C.psittaci in boiler pigeons in Jilin Province,northeastern China,and effective measures should be implemented to reduce the risk of C.psittaci transmission from pigeons to humans.

Background:It was demonstrated that vitamin D has extensive biological effects,and evidence exists on association between vitamin D and a variety of immune mediated diseases such as inflammatory bowel disease. Aims:To investigate the relationship between serum level of 25-hydroxyvitamin D(25OHD)and disease activity and quality of life in patients with ulcerative colitis( UC). Methods:Serum level of 25OHD was detected by electrochemiluminescence in 50 outpatients/inpatients with UC from Oct. 2015 to Mar. 2016 at the Anhui Provincial Hospital;35 healthy subjects were served as normal controls. CRP,ESR and PLT were determined by routine laboratory tests in UC patients. Disease activity of UC was assessed by improved Mayo score,and Chinese version IBD questionnaire( IBDQ)was employed to assess quality of life. Results:Vitamin D deficiency defined as serum 25OHD ﹤20 ng/mL was detected in 68. 0% of the UC patients. The mean value of serum 25OHD was significantly lower in UC group than in normal control group[(16. 73 ± 8. 83)ng/mL vs.(19. 84 ± 4. 56)ng/mL,P﹤0. 05]. When patients were stratified with disease activity,serum level of 25OHD decreased in the order of remission,mild,moderate and severe active stage(P ﹤0. 05). In UC patients with vitamin D deficiency,the value of CRP,ESR and PLT were significantly increased(P all ﹤0. 05)and the overall score of IBDQ and scores of four dimensions of IBDQ referring to bowel symptom,systemic symptom,emotional function and social function were significantly decreased(P all ﹤0. 05). Spearman and Pearson correlation coefficients analyses showed that serum level of 25OHD was negatively correlated with Mayo score,CRP,ESR and PLT(P all ﹤0. 05),and positively correlated with scores of IBDQ,including overall score and four dimensional scores in UC group( P all ﹤0. 05 ). Conclusions:Vitamin D deficiency occurs frequently in patients with UC and might have a negative impact on disease activity and quality of life.

Objective To investigate the association of urinary albumin-to-creatinine ratio (UACR) and the diameter of retinal vessel in population with essential hypertension in Fujian coastal area.Methods Central retinal artery and vein equivalents (CRAE and CRVE) were measured from the avoiding mydriatic digitized photographs and semi-automatic fundus analysis software,as well as albumin and urine creatinine.Results There were significant differences in CRAE levels among the normal control group,normoalbuminuria with essential hypertension group and microalbuminuria with essential hypertension group [(135.68 ± 10.10) μm,(129.79 ± 10.48) μm,(125.29 ± 11.17) μm,all P values ＜0.01].The CRAE levels were significantly negative correlated with UACR (r =-0.29,P ＜ 0.01).Linear regression analysis showed CRAE was associated with UACR in the patients with hypertension(β =-5.0,P ＜ 0.01).Logistic regression analysis showed,systolic blood pressure (β =1.08,P =0.02) was risk factor for CRAE abnormality.The CRAE abnormality was increased in turn in the normal control group,normoalbuminuria with the essential hypertension group and microalbuminuria with essential hypertension group (P ＜ 0.01).Conclusion The reduction of central retinal artery diameter are associated with the hypertensive renal damage.UACR and CRAE could be used to evaluate the microvascular lesions and be used as an indicator to assess the target organs damage in essential hypertension patients.
