Two patients with neonatal diabetes tested as V59A and V59M mutations were chosen for the study. Clinical data were analyzed retrospectively. The results showed that the patient with V59A mutation was characteristic of spasm and hyperglycemia at the age of three month, and treated with insulin for a long time as unresponsive to the glibenclamide at the beginning. Myasthenia and delay of development were observed during the follow-up. At the age of two years, glibenclamide was tried for the second time with a high dose and fairly-controlled glucose level. The patient with V59M mutation was diagnosed with diarrhea, hyperglycemia, and ketosis at the age of two month, and was responsive to glibenclamide at a relatively low dose with well-controlled glucose level. These results suggest that KCNJ11 V59M mutation would show some milder clinical manifestations and better glibenclamide efficacy as compared with V59A mutation.

Whether or not an abormal expression of IL-6 mRNA in PBMNCs from IDDM patientswas examined using a hihgly sensitive,specific and semiquantitative protocal,i.e.reverse tran-scription and polymerase chain reaction (RT-PCR).The relative levels of IL-6mRNA in PBM-NCs from 12 early IDDMpatients (8.20?3.85yr),29 newly diagnosed NIDDM patients(54.85?9.12yr)23 normal childrens (8.20?3.26yr) and 12 normal adults (31.92?11.22yr)weredetermined.Significantly high expresion levels of IL-6 mRNA were found in PBMNCs from pa-tients with IDDM (P

OBJECTIVETo investigate the accurate and individual treatment of temporomandibular joint(TMJ) injury based on 3D digital technology.

METHODSMaxillo-mandibular model was made using rapid prototyping technology based on the pre-operation 3D CT results. According to the 3D digital measurement results, TMJ concepts were ordered and the prosthesis was used to simulate the replacement surgery on the model. Then the joint replacement surgery was performed afterward.

RESULTS(1)After total replacement of TMJ, no pain happened and mouth open was not limited. Three months later, the joint position was normal and stable. The month open width was 4 cm. (2)After condyle replacement, primary healing was achieved with complete survival of bone graft. No edema was seen. Symmetric facial appearance was satisfactory.

CONCLUSIONSBilateral individual prosthesis for total TMJ or condyle replacement is an ideal method for TMJ injury.

Objective To establish a new method, applying high resolution melt, to discriminate the VEB-3 hypotype from the clinical gram negative isolates. Methods From January to December 2003,292 consecutive and non-repetitive gram-negative bacteria producing VEB extended spectrum β-lactamase (ESBL) were collected. Extract the DNA of clinical gram negative isolates with phenol-chloroform. PCR was performed to amplify the VEB gene with the DNA being template. After that, we amplify the fragment of VEB gene containing the position 168. Then we detect the high resolution melt curve and analyze them. At last, we analyze the results of sequence and high resolution melt( HRM ). Results VEB-1 and VEB-3 gene are markedly different through HRM analysis. Conclusion It is accurately and quickly for us to identify the VEB-3 from other hypotype through the technology of HRM.

C8orf32 is a gene which has not been functionally characterized,the mRNA level of this gene is significantly higher in breast cancer tissues than that in normal breast tissues.The amplified cDNA fragment was inserted into the pGEX-6P1 vector fused with the upstream GST gene.The expression vector was transformed into the E.coli BL21(DE3) strain and expression of GST-C8orf32 fusion protein was induced by IPTG..After removal of GST tag by site-specific protease,the C8orf32 protein fused with an eight amino acid peptide tag was obtained.The purity of recombinant C8orf32 protein was about 95%.The identity of the purified protein was confirmed by N-terminal sequencing and tandem mass spectrometry.The polyclonal antibody was prepared by immunizing the New Zealand white rabbits with C8orf32 protein.The polyclonal antibody was proved to recognize the C8orf32 protein correctly.The purified C8orf32 protein can be used for structural and functional studies and the polyclonal antibody can be used for tissue specific protein expression profiling.

Objective To explore the protective effect of insulin-like growth factor 1 (IGF-1) on apoptosis of dopaminergic neurons induced by L-dopa via JAK/STAT signaling pathway. Methods PC12 cells were induced to differentiate into dopaminergic neurons with 100 μg/L β-NGF; MTT assay was employed to identify the changes in the viability of PC12 cells following L-dopa treatment at 0, 10,20, 50, 100, 150 and 200 μmol/L, and the different concentrations of IGF-1 at 0, 10, 25, 50 and 100 nmol/L with the same concentration of L-dopa (150 μmol/L); Western blotting was used to detect the levels of P-JAK2/P-STAT3 in PC12 cells treated with PBS (controls), L-dopa, L-dopa+IGF-1 and L-dopa+IGF-1+AG490 for 24 h, and then the apoptosis rate was assessed by flow cytometry and Hchest33258 staining. Results Western blotting showed that the expressions of P-JAK2 and P-STAT3 were detected in the L-dopa+IGF-1 and L-dopa+IGF-1+AG490 treatment groups but not in the control group or L-dopa treatment group; the expression of P-STAT3 in the L-dopa+IGF-1+AG490 treatment group was obviously lower than that in the L-dopa+IGF-1 treatment group (P<0.05). Hchest33258 staining indicated that L-dopa treatment group had the most obvious karyopyknosis and karyorrhexis,much more apoptotic bodies than the L-dopa+IGF-1 and L-dopa+IGF-1+AG490 treatment groups. Flow cytometry showed that the apoptosis rate was significantly different among the 4 groups (F=180.991,P=0.000): as compared with the control group, the other 3 groups had a higher apoptosis rate (P<0.05);L-dopa treatment group (38.13 ±2.54 %) enjoyed the highest level, followed by L-dopa+IGF-1 +AG490treatment group (25.60±1.30 %) and L-dopa+IGF-1 treatment group (20.17±1.54 %). Conclusion L-dopa has toxic effect on PC12 cells; IGF-1 could protect the PC12 cells from the neurotoxic effect of L-dopa and JAK2/STAT3 signaling pathway is activated in this procedure.

OBJECTIVE To observe the effects of RNA interference mediated PIK3CA gene silencing on the proliferation and invasiveness of laryngeal squamous cell carcinoma(LSCC) cells, and investigate the feasibility of PIK3CA gene as a potential therapeutic target in the treatment of LSCC. METHODS The lentiviral vector system expressing short hairpin RNA targeting PIK3CA gene(PIK3C-shRNA)was constructed and transfected subsequently into Hep-2 cells mediated by liposome in vitro. The expression of PIK3CA gene was detected by real-time RT-PCR and Western blot respectively. The proliferation of Hep-2 cells was measured by MTT, colony formation, and cell growth curve. The invasive power was determined by Boyden chamber model in vitro. RESULTS The lentiviral vector system expressing short hairpin PIK3CA- shRNA was constructed successfully. Compared with the control groups, the mRNA and protein expression of PIK3CA were significantly down-regulated(75% and 70% respectively)in the experimental group (P

OBJECTIVETo translate the original English version of oral health impact profile (OHIP)-14 into Chinese version and to test the psychometric properties of the Chinese version for use among the Chinese adults.

METHODSThe original English version of OHIP-14 was translated into Chinese, and pre-tested and cross-cultural adapted. Subsequently the Chinese version with a general questionnaire was administered to adults aged 18 approximately 65 years by a trained interviewer. Reliability of the translated scale was assessed in terms of internal consistency using Cronbach's alpha and corrected item-total correlation. Construct validity was evaluated by factor analysis and criterion-related validity was evaluated by examining the associations between perceived oral health status, perceived need for dental care and OHIP-14 scores. Formal psychometric properties were tested according to the standard procedure of the international quality of life assessment (IQOLA) project.

RESULTSA total of 592 adults were surveyed. There were 550 valid questionnaires involving 38 ones with missing data. Cronbach's alpha of the translated scale was 0.93, corrected item-total correlation ranged from 0.53 to 0.71. The 14 items were divided into four domains. There was certain logical relation between the items in the same domains. There was highly significant association between perceived oral health status, perceived need for dental care and OHIP-14 scores.

CONCLUSIONSThe translated Chinese version of OHIP-14 demonstrated good reliability and validity. Its good psychometric properties provide the theoretical evidence for further use in Chinese population. It is available for use by researchers in oral health related quality of life studies in Chinese adults.
