Objective To analyze endoscopic histological characters and establish diagnostic standards of colorectal polyps with confocal laser endomicroscopy (CLE) examination and to explore the diagnostic value of the CLE in adenomatous polyps and non-adenomatous polyps. Methods From June to December in 2009, 90 patients were recruited in this study, which included 40 pathologically confirmed colorectal polyps patients (total 48 colon and rectal polyps) and 50 patients for prospective study (total 106 colon rectal polyps). At same time 10 spots of normal mucosa was taken for comparison. Firstly the CLE images of 48 pathologically confirmed colorectal polyps (22 adenomatous polyps and 26 non-adenomatous polyps) were analyzed, and the diagnosis criteria for distinguishing adenomatous polyps and non-adenomatous polyps was established with CLE. Then according to the criteria, 106 colorectal polyps underwent prospective diagnosis with CLE. Finally, the CLE diagnosis result was compared with pathologically result to evaluate the diagnosis efficiency of CLE. Results In the 48 colorectal polyps of 40 pathologically confirmed colorectal polyps patients, there were 22 adenomatous polyps and 26 non-adenomatous polyps. The sensitivity, specificity and accuracy of CLE in adenomatous polyps diagnosis were 94. 0%, 92. 9%, and 93. 4%, respectively. The positive predictive value was 92.2% and the negative predictive value was 94.5%. The sensitivity, specificity and accuracy of CLE in non-adenomatous polyps diagnosis were 92. 9%, 94.0%, and 93. 4%respectively, the positive predictive value was 94.5% and the negative predictive value was 92.2%.The coherence of CLE and histopathology in adenomatous polyps diagnosis was pretty good (Kappa=0. 893). Conclusion The accuracy of CLE in adenomatous polyps and non-adenomatous polyps differential diagnosis was high, and the coherence with histopathology diagnosis was good, which provided experience for further detection of early rectal precancerous.

Objective To investigate renal histopathological changes and cli ni cal characteristics in 20 women with preeclamptic nephropathy or gestational pro teinuria.Methods Between 1999 and 2002, 20 women who suffered from preeclampsia or proteinuria during pregnancy underwent postpartum renal biopsies from fifth d ay to third month after delivery. One woman repeated her renal biopsy half year later. Each biopsy specimen was divided into three parts,and processed and stain ed for conventional light microscopy(LM), immunohistology (IH) and electron micr oscopy (EM) examination. The clinicopathological data were studied and women wer e followed up after discharge for a long time. Results Sixteen of 20 women were diagnosed as preeclampsia, whose altered glomeruli demonstrated a typical endoth elial lesion (endotheliosis), and mild to moderate proliferation of mesangial ce lls. IH revealed either negative or mild IgG、IgM and C3 deposits. Focal glomeru losclerosis (FGS) was observed in one of 16 cases, whose microproteinuria (0 49 g/24 h) lasted for more than one year, meanwhile the proteinuria of other 15 wo men disappeared completely within 3～6 months after delivery. Besides, one was I gA nephropathy (IgAN) complicated preeclamptic nephropathy, whose proteinuria de creased obviously after delivery, but remained microhematuria, and endothelial l esion disappeared in repeat biopsy after half year. One was IgAN and received a treatment of adrenocorticosteroid and immunosupressive agents because of macropr oteinuria. One was mild mesangial proliferative glomerulonephritis presenting co nstant microhematuria and microproteinuria. One was typeⅠmembranous nephropathy , whose proteinuria decreased remarkably after delivery as well. Conclusions Ren al histopathological changes of preeclampsis are typical endothelial lesion, and often recover completely within 6 months after delivery. Recovery may be delaye d in the case of FGS accompanied. Pregnancy may aggravate primary renal damage w hich will be improved after delivery. Postpartum renal biopsy is safe and benefi cial to early diagnosis, treatment and prognosis.

Objective To improve the diagnosis and treatment of primary adrenocortical carcinoma. Methods Retrospective analysis was performed in clinical data of 16 patients with primary adrenocortical carcinoma. The diagnosis was based on clinical presentations,hormonal studies and imaging. Surgical treatment was underwent on 13 cases. All patients were followed up for 3 to 62 months. Results Of 16 cases,functional tumors were in 8,including Cushing′s syndrome in 5,combination of Cushing′s syndrome and virilization in 2,and hyperaldosteronism in 1. Imaging studies revealed the tumors were 4.8 to 19.5 cm in diameter,average in 7.8 cm. Distant metastasis occurred in 3 cases. Radical surgery was done in 13 cases without distant metastasis,including radical adrenalectomy in 8,adrenalectomy plus nephrectomy in 2,adrenalectomy plus surgical extirpation of intracaval tumor thrombus in 2,and partial resection of the wall of inferior vena cava in 1. Pathologic stages were stage Ⅰ in 2 cases,stage Ⅱ in 8,stage Ⅲ in 3,stage Ⅳ in 3. Among the 11 cases who were treated over 2 years after operation,6 cases were still survival,while 1 case had pulmonary and 1 case had bone metastasis. The other 5 cases survive in average of 26 months. Conclusions Prognosis of primary adrenocortical carcinoma is poor. The keys to early diagnosis are clinical manifestations plus imaging. Surgical treatment is the only effective therapy for the disease.

AIM: This study was aimed to assess the effect of mineral trioxide aggregate (MTA) combined with fibronectin on reparative dentinogenesis and odontoblast differentiation, investigate the possible mechanism underlying traumatized pulp repair, which would facilitate the choosing of ideal pulp capping agents. METHODS: 192 teeth from 16 adult cats were used. Class V cavties were prepared on the facial surface. The pulps of cats were exposed mechanically and then capped directly with MTA, MTA combined with fibronectin, calcium hydroxide, fibronectin and starch as control. The pulpal tissue reactions were assessed by light microscopy at healing interval of 1 and 4 weeks.RESULTS: 1 week after pulp capping, no reparative dentin formation was observed in each group. 4 weeks after pulp capping, the dental pulps capped with MTA/fibronectin showed no or slight cellular inflammatory responses and odontoblast differentiation with tublar dentin bridge on the exposed sites. In MTA group, the dental pulps showed slight to moderate cellular inflammatory responses with osteodentin formation. In calcium hydroxide group, the pulps showed moderate to severe inflammatory responses with calcified matrix. In fibronectin and starch group, no dentin bridge formation was observed, the pulps showed severe cellular inflammatory responses.CONCLUSION: (1) MTA combined with fibronectin induced to form complete and tublar dentin bridge. In MTA group, most of the formed dentin bridge was irregular and osteodentin. (2) MTA combined with fibronectin is a bioactive pulp-capping agent and has a great worth in vital pulp therapy.
