The main factor affected the eyesight retrieval was posterior segment pathology.

ObjectiveTo explore the role of activation and expression of absent in melanoma 2 (AIM2) in pathogenesis of hepatitis B virus (HBV) associated glomerulonephritis (HBV-GN).MethodsFifty-four patients with HBV-GN were recruited into the investigational group,and 25 patients with chronic glomerulonephritis (CGN) and 6 patients with chronic hepatitis B (CHB) were included as negative control group and positive control group,respectively.Immunohistochemistry was used to detect AIM2,Caspase-1 and interleukin (IL)-1β expressions in both kidney tissues from the investigational group and negative control group and liver tissues from positive control group.The differences between groups were compared by chi-square test,and the correlation analysis was conducted by Spearman correlation test.ResultsThe positive expression rates of AIM2 in 54 patients of HBV-GN group and 25 of CGN group were 81.4 ％ and 4.0％,respectively (x2 =38.746,P＜ 0.01).AIM2 was found to be expressed in all 6 CHB patients.In HBV-GN group,the expression of AIM2 was positively correlated with Caspase-1 (rs =0.444,P＜0.01),and the expression of IL-1β was also positively correlated with Caspase-1 (rs =0.515,P＜0.01 ).In HBV-GN group,the expression of AIM2 in patients with HBV DNA≥1 ×105 copy/mL was significantly higher than that in those with HBV DNA＜1 × 105 copy/mL (x2 =6.097,P＜0.05).ConclusionThe activation of AIM2 may play a role in the pathogenesis of HBV-GN through Caspase-1 activation and inflammatory factor IL-1β release.

Objective To speculate the precipitating factors,clinical features and histopathological changes in patients with granuloma annulare (GA).Methods A study was performed in 53 patients with GA . Results The incidence of female was more prevalent than male in our study. The exposure of sunlight was found more relatedly in GGA than LGA.The onset age of GGA was inclined to be elder and GGA seemed to last longer.The histopathological study showed that palisading granuloma pattern accounted for 71.7% in all patients,and scattered histiocytic infiltration accounted for 28.3%.Such as cryotherapy,topical steroids were used for LGA and systemic administration was an alternative to GGA. Conclusions Ultraviolet may be associated with the development of generalized GA. The most common pattern is the palisading granuloma though the histopathological changes were variable.Topical therapy is effective in LGA,while the systemic therapy is mainly used for GGA.

A polydimethylsiloxane ( PDMS )/glass microfluidic chip consisting of a three-layer sandwich structure and three-parallel micro-electrode system was fabricated for the separation of polystyrene microspheres according to the particle size in high conductive solution by electric field produced by alternating current. The principle of electrokinetics of microspheres directional movement was investigated. The results showed that, when the applied voltage was 14 V at 100 kHz, the separation efficiency of 10 and 25 μm polystyrene microspheres was the best. Similarly, with a voltage of 10 V at 2 MHz, the separation efficiency of 5 and 25 μm polystyrene microspheres could achieve the highest value. Meanwhile, the voltage of 11 V at 1 MHz was suitable for the separation of 5 , 10 and 25 μm polystyrene microspheres with the separation efficiency of over 90%. At the same time, the formation of the laminar region in the middle of the electrode gap was the key role of microsphere separation.

Objective To investigate the renoprective effect and its possible mechanism of Niaoduqing on the adriamycin(ADR)-induced nephropathy rats. Methods Forty eight male Sprague-Dawley rats were randomly divided into normal control(n=12), ADR-induced nephropathy(model, n = 12), Benazepril-treated ADR nephropathy(Benazepril, n=12)and Niaoduqing-treated ADR nephropathy(Niaoduqing, n =12)groups. The rat nephropathy model was established by adriamycin injection and unilateral nephrectomy. The rats were sacrifficed per batch at the 4th and 8th weekend.The pathological change of nephridial tissue, the 24-hour urinary protein excretion and renal function were examined. Immunohistochemistry was used to meassure the expression of fibronection(FN), collagenⅣ(COLⅣ), osteopontin(OPN). Results The 24-hour urinary protein excretion, BUN, Scr, triglyeride(TG), cholesterol(Cho)in model group were significantly higher than those in normal group(P<0.01), as well as more server glomerulosclerosis in kidney were observed in model group than those in control group(P<0.01), while the albumin(Alb)was lower (P<0.01). Compared with model group, the 24-hour urinary protein excretion, BUN, Scr, TG, Cho were significantly reduced and renal glomerulosclerosis was improved in Niaoduqing group(P< 0.01), while the Alb was higher(P<0.01). Conclusion Niaoduqing palys an important role in the prevention and treatment for nephropathy.

Objective To observe the clinical,pathological features and prognosis of IgA nephropathy in children with crescent formation.Methods A total of 38 cases of children with IgA nephropathy diagnosed by renal biopsy at Qilu Hospital of Shandong University were retrospectively analyzed.According to whether there were crescent formation,they were divided into crescents formation group (crescent formation≥10％,n=18) and control group consisting of children with complete clinical data and matching age,gender and course of disease (no crescent formation,n=20).The clinical,pathological features and prognosis of the two groups were compared.Results Fourteen cases (77.78％) of crescents formation group were associated with nausea hematuria,and 12 cases (66.67％) had hypertension,8 patients in control group (40％) had gross hematuria,and 6 cases (30％)had high blood pressure.The differences were statistically significant (P ＜ 0.05).In crescents formation group,Alb and eGFR were significantly lower than those of control group.24 h urine protein and Scr were significantly higher than those of control group and there were significant statistically differences between two groups (P ＜ 0.05).Nephropathological changes in crescent formation group were mainly in grade Ⅱ and grade Ⅲ and were usually combined with tubular interstitial damages.In addition to IgA immunoglobulin deposition,they often accompanied by IgG and IgM immunoglobulin deposition.In control group,nephropathological changes were mainly in grade Ⅰ and grade Ⅱ and tubular interstitial damages were rare.IgA was the main form of deposition in control group.After 12 weeks steroid treatment and (or) immunosuppressive therapy,urinary protein turned negative in 7 cases in crescent formation group,24 h urinary protein level declined by half than before in 7 cases and no obvious change in 4 cases.In control group,urinary protein turned negative in 12 cases,6 cases showed a more than 50％ decline in urinary protein level and 2 cases had no obvious change.During the 1-3 years of follow-up,renal function of 14 cases and 19 cases was normal in the crescent formation group and control group respectively,serum creatinine of 3 cases and 1 case increased mildly in the crescent formation group and control group respectively,1 case needed dialysis treatment in the crescent formation group and the one in the control group who had slightly increasement of Scr did not reach the standard of dialysis treatment.Conclusions The clinical and pathological manifestations of children with IgA nephropathy with crescent formation are more severe and more likely to manifest renal insufficiency,suggesting that crescent formation is one of the indicators of poor prognosis.

OBJECTIVETo explore the genetic etiology for fetuses with increased nuchal translucency (NT) but a normal karyotype at whole genome level by chromosome microarray analysis (CMA).

METHODSSeventy-eight fetuses with increased NT (≥ 3.0 mm) but a normal karyotype were collected between 11(+0) and 13(+6) gestational weeks. Genomic DNA was extracted, and microarray testing was performed using Affymetrix CytoScan(TM) HD arrays. The data was analyzed by CHAS software. All detected copy number variations (CNVs) were confirmed with real-time quantitative polymerase chain reaction.

RESULTSThe CMA assay has detected pathogenic CNVs in 6 fetuses (7.69%), which have ranged from 0.41 Mb to 15.87 Mb. Well-known microdeletion or microduplication syndromes including Wolf-Hirschhorn syndrome, 22q11 microdeletion syndrome and ATR-16 syndrome were identified in three cases. The detection rates in fetuses with or without structural abnormalities were 18.18% and 5.97%, respectively (P=0.198 with Fisher's Exact Test). The average NT in fetuses with pathogenic CNVs and non-pathogenic CNVs has measured 4.48 mm and 4.22 mm (P=0.735 by Mann-Whitney Test).

CONCLUSIONFor fetuses with increased NT, CMA can identify chromosomal microdeletion/microduplication unrecognizable by conventional karyotyping analysis. It may therefore play an important role in prenatal diagnosis and genetic counseling by improving the diagnostic rate.

The clinical diagnosis of tubulointerstitial nephritis and uveitis (TINU) syndrome combined with Fanconi syndrome is relatively rare. The paper reports a 47-year-old female patient of TINU syndrome with hypokalemia, hypophosphatemia, hypouricemia and renal impairment as initial symptoms followed by uveitis. Serological tests showed that the patient also met the diagnostic criteria of Fanconi syndrome. Renal tissue pathology confirmed tubular interstitial injury, manifested as interstitial nephritis with acute tubular injury. Ophthalmic examination confirmed iritis in the right eye. After excluding other primary diseases, the patient was diagnosed as TINU syndrome with Fanconi syndrome. After glucocorticoid therapy, ocular symptoms, renal impairment and electrolyte disturbance were significantly improved.
