Purpose To evaluate apoptosis in renal tissue of diffuse proliferative lupus nephritis and therelationship between the existence of apoptosis cells in renal tissue and histopathological or clinical changes.Methods Apoptosis was detected by in situ nick-end labeling techniques (TUNEL) in renal biopsies from 25patients with type Ⅳ LN, 12 patients with IgAN, 4 patients with MsPGN, and 3 patients with APSGN. Normalrenal tissue obtained at nephrectorny for hypemephroma in 4 adults was used as control. In addition, proliferatingcells were identified by proliferating cell nuclear antigen(PCNA) in these patients. Results Compared to otherproliferative glomerulonephritis and control,the patients with lupus nephritis had less apoptosis cells, higher ratio ofPCNA+ cells/TdT+ cells/(P/T) in renal tissues;Ratio of P/T in glomeruli and tubulointerstitium correlated withthe chronicity index, r=0. 498 3(P = 0. 013 2), r = 0. 839 9(P＜ 0.001 ), r = 0. 661 4(P = 0. 003 3),respectively. Ratio of P/T in glomerulus and tubule had positive correlation with 24 hour urinary protein, r =0.855 4(P＜0.001),r=0.713 4(P=0. 001); negative correlation with Ccr, r = - 0. 488 0(P =0. 013 3)and r = - 0. 722 9(P = 0. 001), which in tubules positively correlated with Scr, r = 0. 410 7 (P = 0.041 4 ).Conclusions Apoptosis is insufficient in proliferative lupus nephritis. Intense proliferation without followingincrease in apoptosis may be related to chronic progressive renal histopatholcgical changes.

Through several thousand years’ inheritance and development by Chinese people, traditional Chinese medicine (TCM) has formed its unique theoretic system, whose efficacy has been widely accepted. However, because TCM theory focuses on the relationships among syndromes, treatment and efficacy, instead of the cause-and-effect relationship explored by modern natural science, the scientificity of TCM has always been questioned. In recent years, because virtual-world clinical research mode and the concept of “big data” were emphasized, increasing researchers began to put their research emphasis on the correlativity between intervening measures of diseases and outcome indicators. This change and the advancement of computer data mining and analysis technology, bring great opportunities for the further development of TCM theory and practice. This article concluded data mining technology used in TCM diagnosis and treatment in recent years, such as clustering analysis, decision tree, Bayesian network, neural network and multi-instance learning, which showed how to apply these methods to reveal rules of TCM diagnosis and treatment from a large number of TCM syndrome data, find knowledge hidden in data, and show TCM effectiveness supported by data.

Two cases of incomplete regression of ventral mesogastrium were reported. Their nomenclature, etiology, symptoms and characteristic roentgenologic findings were discussed in relation to anatomical study. Because of its unique etiology and symptoms, charecteristic roentgenologic findings, and effectual remedy, it is suggested that this disease should be distinguished from "abnormal adhesion of fibrous bands" as an independent anomaly called incomplete regression of ventral mesogastrium. The roentgenological findings were: An incisure was found in the upper portion of pars descendens duodeni. It sank deeply and reduced two thirds of the normal diameter of the intestinal lumen to form an eccentrie intestinal stenosis. The intestinal lumen, near the inner border of the incisure was smooth, and there was no sign of serrated image formed by intestinal mucosa. The part of intestinal lumen was not distended in hypotonic radiography. All the above signs were caused by the traction and binding of the nonregressed mesogastrium.

OBJECTIVETo investigate the correlation between enhanced computed tomography (CT) findings and pathological results of rare parotid gland tumors, and improve diagnosis accuracy.

METHODSThe enhanced CT manifestations of 22 cases with pathologically documented rare parotid gland tumors, which included 6 cases of basal cell tumor, 5 cases of myoepithelioma, 4 cases of vascular invasion, 3 cases of lymphatic cyst, 3 cases of lipoma, and 1 case of chondrosarcoma, were retrospectively analyzed. The location, size, shape, density, and relationship with surrounding structure were evaluated on CT images.

RESULTSThe enhanced CT showed that basal cell tumors occurred in the superficial lobe of the parotid gland, with clear boundary, within the cystic lesion. The lesions were moderate to obviously enhanced, which may be accompanied by enlarged lymph nodes. Myoepithelial tumors were located in the superficial lobe of the parotid gland, with a small cystic prone and microcalcification within a few cases. The lesions were moderate to obviously enhanced. Hemangiomas of soft tissue mass prominent in the parotid gland surface were mild to significantly enhanced. Larger lesions may occupy the entire parotid gland, with uneven density and visible vein stone. The CT density values of the lymphatic cyst were usually higher. Chondrosarcoma mainly manifested cystic mass at the calcification edge. Lipoma with fat density mass exhibited clear boundary without enhancement. Fiber separation could be observed in the lesion.

CONCLUSIONCT can reflect the pathological features of rare parotid gland tumors by demonstrating their corresponding imaging features. Enhanced CT is the most effective means of imaging to identify the nature of rare tumor of the parotid gland lesions.
