The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

OBJECTIVETo study the clinical characteristics of ceftriaxone-associated biliary pseudolithiasis in children with renal diseases.

METHODThree children with renal diseases developed biliary pseudolithiasis when they were treated with ceftriaxone. Their clinical and laboratory data were retrospectively analyzed.

RESULTSCase one was an 11-year-old boy. The initial diagnosis was primary nephrotic syndrome. Ceftriaxone was administered intravenously at a dose of 2 g/d [50 mg/(kg * d)] for gastroenteritis. After that the boy complained of nausea and loss of appetite. Abdominal sonogram obtained on day 3 of ceftriaxone therapy revealed gallbladder sludge. After cessation of ceftriaxone treatment, symptoms and ultrasound abnormalities gradually disappeared, with complete sonographic resolution after 16 days. Case two was a 10-year-old boy. The primary diagnosis was post-streptococcal glomerulonephritis with acute renal failure. The child was treated with 1.5 g/d [30 mg/(kg * d)] intravenous ceftriaxone for gastroenteritis. After that, the boy complained of nausea and abdominal pain with positive Murphy's sign. Gallstone was detected by ultrasonographic examination on day 6 of ceftriaxone therapy. After cessation of ceftriaxone treatment, symptoms and sonographic abnormalities gradually disappeared, with complete sonographic resolution after 18 days. Case three was a 12-year-old boy. The primary diagnosis was nephrotic syndrome. He was treated with 2 g/d [40 mg/(kg.d)] ceftriaxone for gastroenteritis. Gallbladder lithiasis was detected 17 days after the initiation of ceftriaxone therapy (3 days after cessation of ceftriaxone treatment). Gallbladder sonogram was found to be normal two months after the discontinuation of the therapy.

CONCLUSIONSBiliary pseudolithiasis occurred in 3 cases with renal diseases receiving low doses of ceftriaxone. The risk of developing ceftriaxone-associated biliary pseudolithiasis might increase in patients with renal diseases who are treated with ceftriaxone.

OBJECTIVESTo establish a primary biliary cirrhosis (PBC) model by AMAM2 autoantigen injection into C57BL/6 mice.

METHODSMice of the model group were immunized intraperitonealy with 200 microl of purified recombinant AMAM2 autoantigen in complete Freund's adjuvant (CFA). Mice immunized with bovine serum albumin and CFA in the same way were used as negative controls. Sixty-six weeks later, mice were sacrificed and their sera were collected. Sera samples were assayed for AMAM2 autoantibody, alkaline phosphatase (ALP), ALT and total bilirubin (TBil). Their liver, stomach, muscle and kidney tissues were sectioned and stained using HE to observe the pathological changes.

RESULTSAntibodies to AMAM2 autoantigen were readily induced in the model group. The mice in the model group had no significant changes in the level of serum ALT and TBil but had an obvious increase of ALP (P<0.05). The stomach, muscle and kidney tissues showed no evident damage while the livers had obvious pathological changes, including bile duct degeneration or proliferation, and mononuclear cell infiltration.

CONCLUSIONThe AMAM2 autoantigen-induced PBC animal model was successfully established in C57BL/6 mice in our experiment and its characteristic biochemical and pathology are quite similar to that in the early stage of human PBC. This model may provide a useful experimental approach for further study of the pathogenesis and clinical treatment of human PBC.

This study was purposed to investigate the inhibition of hTERT antisense oligodeoxynucleotide (ASODN) on the proliferation and telomerase activity in HL-60 cells and to explore the relativity between the telomerase activity and the expression of hTERT gene in HL-60 cells. After treated by hTERT ASODN the expression of hTERT was detected by RT-PCR, the morphological changes of HL-60 cells was observed with inverted microscopy, the cell proliferation was measured by MTT method, and the telomerase activity was determined with TRAP-ELISA and TRAP-PAGE. The results showed that after sealing hTERT gene with ASODN for 72 hours, the expression of hTERT gene was significantly inhibited, the cell growth was repressed and the ability of proliferation decreased, and the effect was specific in sequence and dependent in dose and time. OD(450-690) values were 2.648 +/- 0.42, 1.504 +/- 0.47, 1.223 +/- 0.39, 0.944 +/- 0.16 respectively, as the cells were treated with 0, 10, 20, 30 micromol/L ASODN for 72 hours. The difference was significant as compared 10, 20, 30 micromol/L groups with 0 micromol/L ASODN group respectively (P < 0.05), but the difference was no significant when compared 20 micromol/L SODN group (2.376 +/- 0.65) with untreated group (2.648 +/- 0.42) (P > 0.05). TRAP-PAGE detection revealed that comparing ASODN groups with SODN groups the telomerase image bands were decreased and least was found in groups of 30 +/- mol/L. It is concluded that the hTERT ASODN may inhibit the proliferation and down-regulate the telomerase activity in HL-60 cells by sealing the expression of hTERT gene.

OBJECTIVETo explore the main points of clinical differentiation between hemangioma and vascular malformation in infant.

METHODSBased on Mulliken and Waner's classification, from March, 1997 to February, 1999, 81 baby patients with hemangioma were included in this study. Thirty-eight cases, 43 cases received medical treatment of steroids.

RESULTSAll the patients were followed up from 5 to 7 years. Thirty-eight cases of red strawberry-like lesions limited in the skin began to involute within two years old. Of the 30 patients with strawberry-like lesions and subcutaneous mass, 20 cases involuted in varying degree; 10 cases' subcutaneous mass grew gradually and didn't involute, in 4 cases biopsy was performed, 3 cases were confirmed as hemangioma accompanied with venous malformation by pathology, 1 case was hemangioma accompanied with arteriovenous malformation. Of 13 cases with light blue or normal skin and subcutaneous mass, 7 cases involuted in varying degree; 6 cases grow gradually and didn't disappear, 2 cases were confirmed as venous malformation by biopsy.

CONCLUSIONSHemangioma in infant begins to involute within two years old. Vascular malformation or hemangioma with deep vascular malformation grows persistently and does not disappear. Skin temperature of lesion surface and dilative veins on the skin artery pulsation, are indexes compressibility, for differentiation between hemangioma and vascular malformation in clinical diagnosis.
