OBJECTIVETo identify the RUNX2 gene mutation in two unrelated Chinese families with cleidocranial dysplasia (CCD), and to assess the feasibility of gene diagnosis for patients with CCD.
METHODSGenomic DNA was isolated from peripheral blood samples of 4 patients and 4 healthy members in the two pedigrees as well as 102 unrelated healthy controls. All 7 coding exons and their flanking intronic sequences of the RUNX2 gene were amplified by PCR, then the PCR products were sequenced bi-directionally. The sequencing results were compared with normal sequences in GenBank to identify the mutation. The mutation was confirmed by RFLP with restriction endonuclease.
RESULTSIn one family, a novel heterozygous missense mutation c.346T to A (W116R) in exon 1 of the RUNX2 gene was detected in the two affected individuals, and the mutation was further confirmed with Bsr I restriction endonuclease digestion. In the other family, a novel nonsense mutation c.610A TO T (K204X) was identified in the two patients. No above sequence change was found in the 102 healthy controls.
CONCLUSIONTwo novel RUNX2 mutations were found in two unrelated Chinese families with cleidocranial dysplasia. The identification of these mutations further extended the mutation spectrum of RUNX2 gene and will facilitate prenatal diagnosis and gene diagnosis of CCD.

OBJECTIVETo evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD).
METHODSA multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed.
RESULTSAmong the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001).
CONCLUSIONBFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.

OBJECTIVETo ascertain whether other variations coexist with 1555(A--> G) mutation in the mitochondrial DNA and may aggravate the severity of hearing loss or increase the penetrance of 1555(A--> G) mutation in a large family with maternally inherited nonsyndromic deafness in Huaiyin, Jiangsu province.
METHODSPCR-restriction fragment length polymorphism (PCR-RFLP) was used to screen both the nt1555 and the nt7445 of the mitochondrial DNA from 27 maternal members in the core family; and then the mitochondrial genomes from two maternal members, and the 12S rRNA genes MTRNR1 and tRNA-Ser(UCN) gene MTTS1 from the others, were amplified by PCR-RFLP and were sequenced.
RESULTS1555(A--> G) mutation in the mitochondrial DNA was reverified to be one of the major factors which cause maternally inherited nonsyndromic deafness and the cosegregation of 955-960(insC) and 1555(A--> G) was present in this family. Moreover, 7449 (insG), a novel homoplasmic mutation in the tRNA-Ser(UCN) gene, was found to co-exist with 1555(A--> G) mutation in two maternal members.
CONCLUSIONThe cosegregation of 955-960(insC) and 1555(A--> G) implies that 955-960(insC) may synergistically cause hearing loss in the presence of an 1555(A--> G) mutation, serving as an aggravating factor to enhance the sensitivity to aminoglycosides, and may sometimes increase the penetrance of 1555(A--> G) mutation.

OBJECTIVETo ascertain whether connexin 26 (Cx26) gene was a nuclear modifier gene in an extensive family with matrilineal nonsyndromic deafness associated with A1555G mutation in Huaiyin, China.
METHODSFollowing PCR-restriction fragment length polymorphism (PCR-RFLP) with ApaI restriction enzyme, Cx26 genes from 26 cases, with A1555G mitochondrial mutations in this family, and 62 controls (including 2 patrilineal relatives, 10 spouse controls and 50 unrelated controls), were sequenced.
RESULTSCompared with the reference sequence of Cx26 gene, totally four kinds of nucleotide changes,79G -->A, 109G-->A, 341G-->A and 235delC, were detected in a heterozygous form. However, the former three were previously reported polymorphisms, and only the 235delC was a previously described recessive mutation associated with most autosomal nonsyndromic sensorineural hearing loss in Japan and China. Further study showed that the heterozygous 235delC mutation existed in both one individual with mild hearing loss and two individuals with normal hearing. Clinical characterization showed that 235delC mutation did not seem to modify the deafness phenotype due to the A1555G mutation. Moreover, this 235delC mutation was deduced to derive from a married-in control. Finally, there were no co-segregation between the phenotypes of hearing loss and the genotypes for Cx26 genes based on the four kinds of nucleotide changes.
CONCLUSIONSThe heterozygous 235delC mutation of the Cx26 gene may not modulate the severity of hearing loss associated with A1555G mutation and Cx26 gene is unlikely to be a modifier gene for hearing loss due to A1555G mitochondrial mutation in this Chinese family.

Objective To discuss the effect and mechanism of miR-34a on the proliferation, apoptosis and invasion of laryngeal carcinoma cells. Methods The laryngeal squamous carcinoma Hep2 cells were transiently transfected with miR-34a mimics and miR-34a NC. The MTT, colony-forming assay, Hoechst staining and AnnexinV-PI double staining flow cytometry were employed to detect the effect of miR-34a on the viability and apoptosis of laryngeal squamous carcinoma Hep2 cells; Transwell assay to defect the effect of miR-34a on the migration and invasion of laryngeal squamous carcinoma Hep2 cells; western blot and RT-PCR assay to defect the effect of miR-34a mimics on the expression of survivin and Ki-67 mRNA in laryngeal squamous carcinoma Hep2 cells. Results Compared with miR-34a NC group, the cell viability in miR-34 mimics group was significantly decreased (P < 0.01), the cell apoptosis rate was significantly increased (P < 0.01), the abilities of cell migration and invasion were significantly reduced (P < 0.01) and the expression of survivin and Ki-67 mRNA was significantly decreased (P < 0.01). Conclusions The increased expression of miR-34a can induce the apoptosis of Hep2 laryngeal carcinoma cells and inhibit the cell proliferation and invasion, which is related to the down-regulated expression of survivin and Ki-67.

Objective: To investigate the mechanism of survivin, p53 and Ki-67 on Hep-2 human laryngeal cancer endothelial cell proliferation and invasion. Methods: Laryngeal squamous cell carcinoma and paracancerous normal tissues were collected, total RNA was extracted from tissues, survivin, p53 and Ki-67 gene mRNA expression levels in laryngeal cancer and the adjacent tissues were detected by Real-time PCR. Human laryngeal cancer Hep-2 epithelial cells were selected, survivin gene was overexpressed, and cell proliferation was detected by MTT. p53 and Ki-67 gene expression changes in overexpressed survivin gene were detected by Western blot. Changes in Hep-2 cell invasive ability were studied when survivin was overexpressed as detected by Transwell invasion assay. Results: In the adjacent tissues, survivin, p53 and Ki-67 gene relative expression levels were 1.72 ± 0.9, 13.7 ± 5.7 and 5.7 ± 1.3, respectively; while in cancer tissues, gene relative expression levels were 53.7 ± 8.3, 66.7 ± 5.2 and 61.0 ± 3.1, respectively, which was significantly increased. As detected by MTT, relative cell survival rate within 12 h of survivin overexpression were: load control group (88.5 ± 1.6)%; overexpressed group (90.3 ± 1.9)%. Transwell invasion assay results indicated that overexpressed survivin could significantly increase the relative survival rate of cells. Conclusions: Expressions of p53, Ki67 and survivin are increased in cancer; and there is a positive correlation between survivin, p53 and Ki67 expressions in laryngeal carcinoma.
