BACKGROUNDThe epidemiologic pictures of Kawasaki disease (KD) in Shanghai from 1998 through 2002 were reported, while the current status of KD in the following five years remains unknown.

METHODSA questionnaire form and diagnostic guidelines for KD were sent to 50 hospitals providing pediatric medical care in Shanghai, China. All patients with KD diagnosed during January 2003 through December 2007 were recruited.

RESULTSIn total, 1187 cases of KD were enrolled. The incidence of KD was 36.78 to 53.28 (mean 46.32 ± 6.51) per 100 000 children under the age of 5 years between 2003 and 2007, which was higher than the year from 1998 to 2002 of (27.32 ± 7.11) per 100 000, (t = 4.406, P = 0.002). Ages at onset ranged from 12 days to 13.6 years (median 1.8 years). It occurred more frequently in summer and spring. Coronary arterial lesions (CAL), defined as ectasia or aneurysm, accounted for 19.8% (232 cases). Flattened or inverted T wave was the most frequent finding (194 cases, 20.5%) by electrocardiogram. Intravenous gamma-globulin was administrated to 1028 cases (86.6%). The occurrence of CAL seemed less frequent in the patients received gamma-globulin from day 5 to day 9 after the onset with the regimen of 1000 mg/kg once or 1000 mg/kg twice.

CONCLUSIONSThe incidence of KD was increasing in Shanghai. Treatment with intravenous gamma-globulin from day 5 to day 9 after the onset with the regimen of 1000 mg/kg once or 1000 mg/kg twice resulted in less coronary sequelae.

This study was aimed to investigate the effects of oxaliplatin on human multiple myeloma cell line RPMI-8226 and its mechanism. The proliferation inhibitory rate of RPMI8226 cells was assayed by MTT, the morphological changes of RPMI-8226 cells were observed by inverted fluorescent microscopy and transmission electron microscopy, the apoptosis rate and the cell cycle distribution of RPMI-8226 cells were detected by flow cytometry, The effects of oxaliplatin on the expression of Bcl-2, caspase-8, caspase-3 mRNA were tested by RT-PCR, Bcl-2 protein expression of RPMI-8226 cells was analyzed by Western blot. The results showed that oxaliplatin could inhibit the proliferation of RPMI-8226 cells in time and dose-dependent manners. Cell number in oxaliplatin group was significantly less than that in control group under light microscope, and the growth arrangement was irregular, apoptotic cells could be seen. Under electron microscope, typical apoptotic morphological and ultrastructural changes could be observed. Flow cytometry results showed that oxaliplatin could induce apoptosis of RPMI-8226 cells, the difference have statistical significance (P < 0.05). Oxaliplatin mainly arrested RPMI-8226 cells in the S phase (P < 0.05). The expression of Bcl-2 mRNA did not have apparent change, while the expression of caspase-8, caspase-3 mRNA increased (P < 0.05). Western blot results suggested that the expression of Bcl-2 protein had no obvious change. It is concluded that the oxaliplatin can induce apoptosis of RPMI-8226 cells, activating the death receptor pathway and arresting cell cycle may be two of the related mechanisms, Bcl-2 gene has unobservable effects in the process of oxaliplatin-induced cell apoptosis.

This study was aimed to investigate the effects of docetaxel on proliferation and apoptosis of multiple myeloma cell line RPMI8226 and its mechanism. The inhibitory rate of multiple myeloma cells was detected by MTT, the morphological and ultrastructural changes of RPMI8226 cells were observed by using inverted fluorescent microscope and transmission electron microscope, the apoptosis-inducing effect of docetaxel on RPMI-8226 cells was determined by flow cytometry with Annexin-V FITC/PI staining, the cell distribution in cell cycle of RPMI-8226 cells was assayed using flow cytometry with PI staining; the effect of docetaxel on expression of BCL-2, caspase-8, caspase-3 mRNA was detected by semiquantitative RT-PCR, the expression changes of BCL-2 protein in RPMI-8226 cells before and after treatment with docetaxel were measured by using Western blot. The results indicated that 0.25 - 8.0 µg/ml docetaxel obviously inhibited the proliferation of RPMI-8226 cells in both time- and dose-dependent manners. Cell number of docetaxel-treated group was significantly less than control group under inverted fluorescent microscope, and the cell arrangement was irregular, necrotic cells could be seen occasionally. By transmission electron microscope, the morphological and ultrastructural changes of cell typical apoptosis could be observed, a few necrotic cells could be captured, too. Compared with control group, docetaxel induced the apoptosis of RPMI-8226 cell line (P < 0.01). Docetaxel mainly arrested RPMI-8226 cells in the G(2)/M phase (P < 0.01). The expression of BCL-2 mRNA decreased (P < 0.05), while the mRNA expression of caspase-8 and caspase-3 increased (P < 0.05). Western blot indicated that BCL-2 protein expression also decreased (P < 0.05). It is concluded that docetaxel can inhibit the proliferation of RPMI-8226 cells by inducing cell apoptosis. Activation of the mitochondrial and death receptor pathways of apoptosis may be involved in the docetaxel-induced apoptosis, cell cycle arrest may also play an important role in the apoptosis mechanism.

OBJECTIVETo analyze 68 pediatric cases with functional univentricle heart who underwent bidirectional Glenn procedure during from April 1998 to December 2005.

METHODSThere were 47 males and 21 females in this group, aged from 5 months to 14 years old and weighed from 6.7 to 30.0 kg. Among them, 39 cases were received bidirectional Glenn procedure on the right side, 13 cases on the left side and 16 cases on both sides. Three cases had the pulmonary artery banded; one case had the pulmonary artery ligated;one case had the original A-P shunt cut off; six cases had the PDA ligated; four cases had the MAPCAs cut off; one case had TAPVC corrected contemporarily; two cases of PAPVC were also corrected; four cases had the atrial-ventricular valve repaired.

RESULTSThree cases died. The mortality was 4.4%. The mean post-operative pressure of super vena cava was (15.9 +/- 2.4) mm Hg (1 mm Hg = 0.133 kPa), higher than the pre-operative one (8.3 +/- 1.8) mm Hg (P < 0.01). The mean post operative SpO(2) was (89.3 +/- 4.2)%, higher than the pre-operative one (78.4 +/- 6.0)% (P < 0.01).

CONCLUSIONSBidirectional Glenn procedure is of satisfied effect on surgical treatment for functional univentricle heart. The persistent forward flow from pulmonary artery should be reserved in bidirectional Glenn procedure.
