Alagille syndrome (AGS) is a multisystem disorder and caused by mutations in JAG1 or NOTCH2 gene.The diagnosis of AGS is hampered by its highly variable clinical manifestations.We performed a retrospective analysis on 16 children diagnosed as having AGS in recent five years in our hospital.Cholestasis was seen in 15 patients (93.8％),heart disease in 12 (75％),characteristic facies in 7 (43.8％),and butterfly vertebrae in 7 (43.8％).Ophthalmology examination was not performed on all the patients.Further,serum biochemical parameters were compared between AGS and 16 biliary atresia (BA) patients who were confirmed by surgery.Elevated liver enzymes were seen in all the patients.Serum total cholesterol (TC) (P=0.0007),alanine aminotransferase (ALT) (P=0.0056),aspartate aminotransferase (AST) (P=0.0114),gamma-glutamyl transferase (GGT) (P=0.035) and total bile acid (TBA) levels (P=0.042) were significantly elevated in AGS patients compared to those in BA cases.However,there were no significant differences in serum total bilirubin (TB),conjugated bilirubin (CB) and albumin (ALB) between the two groups.We identified 14 different JAG1 gene variations and 1 NOTCH2 gene mutation in 16 Chinese AGS patients.Our study suggested clinical features of AGS are highly variable and not all patients meet the classical diagnostic criteria.It was suggested that hypercholesterolaemia and significantly elevated GGT,TBA and ALT may be helpful to diagnose AGS.Genetic testing is integral in the diagnosis of AGS.

OBJECTIVETo explore the relationship between angiotensin converting enzyme (ACE) gene single nucleotide polymorphisms (SNP) and premature coronary heart disease (PCHD) patients with blood stasis syndrome (BSS).

METHODSrs4343, rs4293, and rs4267385 were selected at SNP from ACE gene. Allele and genotype were detected. Frequencies of allele and genotype were compared by using time-of-flight mass spectrometry technique (TOF-MS).

RESULTSCompared with the healthy control group, genotype of rs4293 and rs4267385 in ACE gene were similar, but there was statistical difference in polymorphisms and allele frequencies of rs4343 in the I and II group (P < 0.05, P < 0.01). The frequency of G allele was higher in the 3 groups than in the healthy control group (P < 0.05, P < 0.01). The relative risk analysis showed that the risk for PCHD occurrence in G allele carriers at rs4343 (GG +AG) was 3. 6 times the risk in non-G allele carriers (95% CI: 1.224-10.585, P = 0.02). There was also statistical difference in sex, age, TC, and TG after adjusted Logistic regression analysis (OR = 3.994, 95% CI: 1.230-12.974, P = 0.021).

CONCLUSIONThe polymorphism at rs4343 (G2350A) might be one of risk factors for PCHD occurrence, but not a predisposing factor for PCHD patients of BSS.

OBJECTIVETo observe the action of Chinese herbal preparation (CHP) on the recovery of nasal sinus mucosa after endoscopic sinus surgery (ESS).

METHODSSeventy-eight patients (140 sinus) with chronic nasosinusitis and nasal polyps, who had undergone ESS, were divided into two groups. The 40 patients (70 sinuses) in the experiment group were treated with daily nasal flushing with diluted CHP while the 38 patients (70 sinuses) in the control group were untreated. Tissues of nasal mucosa were taken out from patients' posterior walls of maxillary sinus at different time points, i. e. 2 - 3 weeks, 8 - 11 weeks and 13 - 15 weeks after ESS were observed.

RESULTSSignificant difference was shown between the two groups under endoscope at all the time points in occurrence (patient/sinus) of sticky mucus, swelling and thickened mucus, occlusion of sinus opening, bloody secretion in sinus, and adhesion, etc. (P < 0.05, P < 0.01). Light microscopic examination showed significant difference between the two groups in occurrence (patient/sinus) of squamous epithelial metaplasia and fiber tissues proliferation (P <0.05). And electron microscopic examination also showed significant difference between the two groups in occurrence (patient/sinus) of inflammatory cell infiltration, fibers decrease, disordered arrangement, microvilli and short cilia (P<0.01).

CONCLUSIONUsing CHP for postoperative nasal flushing after ESS is a safe and manageable approach with effects in promoting nasal mucosa recovery.

OBJECTIVETo investigate the effects of celecoxib combined with radiotherapy on apoptosis of CNE-2Z cell lines and the potential mechanisms.

METHODSFour groups were used, a control, celecoxib (25 micromol/L celecoxib), irradiation (8 Gy X ray) and celecoxib plus irradiation. The radiosensitising effect was detected by clone formation experiment. Flow cytometry was used to detect the apoptosis rate of cells. The expressions of Bcl-2 and Bax were assessed by immunocytochemistry. Western blot was used to examine the expression of Caspase-3.

RESULTSCelecoxib enhanced the radiosensitivity of CNE-2Z cells. In experimental group, the mean surviving fraction and the mean lethal dose of CNE-2Z cells were 0.50 and 2.36 respectively. Compared with the irradiated group, there was significant differences between the two groups (P < 0.01). Celecoxib combined with radiotherapy up-regulation the expression of Bax. The score of the expression of Bax in the control group and the experimental group were 1.221 +/- 0.116 and 2.758 +/- 0.256 respectively. Celecoxib combined with radiotherapy could inhibit the expression of the protein of Bcl-2. The score of the expression of Bcl-2 in the control group and the experimental group were 2.559 +/- 0.144 and 1.253 +/- 0.114 respectively, with significant differences (P < 0.01). Celecoxib combined with radiotherapy could increase the apoptosis rate of tumor cells with significant differences (F = 7.63, P < 0.01). Western blot showed that the expression of Caspase-3 was strengthened.

CONCLUSIONCelecoxib combined with radiotherapy could induce apoptosis and enhance the radiosensitivity of human nasopharyngeal carcinoma CNE-2Z cell lines.

Objective To investigate the effects of dominant-negative truncation mutant?NTCF4, lacking the N-terminal form of TCF4 gene,on biological characteristics of renal cancer cell line GRC-I and explore the molecular mechanisms.Methods GRC-I cell was transfected with pCDNA3-?NTCF4 eukary- otie expression plasmid,pCDNA3 empty vector to construct the stable cell line GRC-I/?NTCF4 and GRC-I/ Mock respectively.The morphological changes of stable cells were observed and the cells growth curve was detected through light microscope.The cellular proliferation activities were determined using the MTT assay. The protein expression of Wnt pathway downstream target gene C-Myc and Cox-2 was evaluated by immuno- cytoehemieal method and Western Blot analysis.Results After the dominant-negative?NTCF4 gene was permanently expressed,the GRC-I/?NTCF4 stable cells morphologically showed that appearance changed from circular to long-spindle shape,growth rate decreased with less karyosehisis found,malignant pheno- types reversed to normal renal tubular cells.MTT assay revealed that the proliferation activities of GRC-1/?NTCF4 cells were inhibited by 11.2%-35.5% compared with GRC-I cells (P＜0.05),while the GRC- I/Mock cells have no difference with the control cells.Immunocytochemical analysis and Western Blot showed that the C-Myc and Cox-2 protein expression level of GRC-I/?ANTCF4 cells were significantly sup- pressed in comparison with that of GRC-I/Mock and GRC-I cells.Conclusions The dominant-negative truncation mutant?NTCF4 could partially inhibit the growth of renal cancer cells and down-regulate the pro- tein expression of Wnt pathway target gene C-Myc and Cox-2.These findings provide a experimental founda- tion for applying cell signal therapy to renal cell cancer by blocking the Wnt signaling pathway.

The complete coding sequences of Eya gene family was amplified by standard PCR fromhuman tissues or cells cDNA library.The product of PCR was cloned into the eukaryotic expression vector pcDNA3-FLAG,generating pcDNA3-FLAG-Eya1～4.Thenhuman embryo kidney 293T cells were transfected with the recombinant plasmids and the expression of Eya genes were identified by Western blot.Transcriptional assay using a reporter containing myogenin enhance factor indicated that expression of Eya cooperation with Six in 293T cells affected the Myogenin gene expression.The expression vectors of Eya genes were constructed and confirmed by restriction enzyme digestion and DNA sequence analysis.Transcriptional assay using a reporter containing myogenin enhance factor indicated that expression of Eya in coordination with Six in 293T cells stimulated the Myogenin gene expression.Eya proteins are transcriptional activator of Six and can improve the activity of myogenin promoter.
