Objective To explore the molecular mechanisms of primary amenorrhea by using arrayCGH technology. Methods Ten patients with primary amenorrhea and 10 female volunteers with regular menstrual cycles as healthy controls were selected. All patients and control samples were analyzed by conventional chromosome analysis (G-banding technology) and array-CGH technology, respectively. ArrayCGH was performed using Affymetrix Cytogenetic 2. 7M arrays following the manufacturer's standard protocol. Results Both the patient group and control group analyzed by conventional G-banding karyotype technology showed a negative result with a normal female karyotype: 46, XX. The result of array-CGH analysis demonstrated a microdeletion of approximately 110 000 bp located at the end of the short arm of X chromosome [46, X, del (X) (p22. 33 )] were identified in 5 patients, which was not detected in the control group. All healthy control samples by array-CGH analysis showed no pathological DNA copy number variation. Conclusions Array-CGH technology can improve the diagnosis rate of chromosomal disease at the DNA level. It is necessary to provide array-CGH for higher resolution genetic analysis of idiopathic primary amenorrhea patient who can not be identified by conventional technology.

Objective To investigate the changes of electrode impedance,threshold(THR),maximum comfortable level(MCL),and dynamic range(DR),providing the basis for debugging after operation in congenital deaf children. Methods A respective study was carried out on 20 cases of congenital deaf children who were implanted with cochlear Med?EL SONATAti100. The measurements and changing ranges of electrode imped?ances,THR,MCL and dynamic range during the operation and at postoperative one month,three months,and six months were statistically analyzed. Results Electrode impedances were the lowest during the operation and the highest at one month after operation(P<0.01). The electrode imped?ance for the apical cochlear group was statistically different from that for other groups at one month(P<0.05). After three and six months,there were statistically significant differences between groups(P<0.01). THR at six months was lower than that at three months(P<0.05). MCL at three months was higher than that at one month(P<0.01). DR showed an increasing trend(P<0.05). There was no correlation of perioperative and post?operative electrode impedance with THR,MCL,and DR(P>0.05). Conclusion The electrode impedances varied due to different electrode posi?tion. The vales of THR,MCL and DR were unrelated with electrode impedance. DR was gradually increasing,MCL reached steady state earlier than THR. It is important that THR should be debugged at three months after operation and MCL should be debugged at six months.

Objective The purpose of this study was to investigate the differences of cognitive impairment and neuropsychiatric behavior disturbances between Alzheimer's disease (AD) and frontotemporal dementia (FTD) patients,as well as their relationships with dementia severity.Methods A total of 38 FTD patients and 46 AD patients were recruited in this study.The Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) were used to evaluate the degree of cognitive impairments.The Neuropsychiatric Inventory Brief Questionnaire Form (NPI) and Frontal Behavioral Inventory (FBI) were used to measure behavioral disturbances.The 21-items Hamilton Depression Rating Scale (HAMD-21) was used to evaluate the mental or emotional state of patients.Clinical dementia rating scale (CDR) was used to divide the dementia severity.Results FTD patients were younger ((70.13 ± 8.36) years vs (66.46 ± 7.04) years,t =2.124,P =0.037),earlier at age of onset ((68.58 ± 8.51) years vs (64.43 ± 6.82) years,t =2.396,P =0.019),with lower MoCA scores (12.50 (8.00,16.25) vs 17.00(10.75,21.00),Z=-2.428,P=0.015),higher NPI (15.00(7.00,25.50)vs 9.50(4.00,17.75),Z=-2.251,P=0.024),FBI (21.00(13.00,27.00)vs 16.00(10.75,23.00),Z=-2.159,P=0.031),FBI-A (13.00 (8.00,16.00)vs 9.00(6.00,12.00) Z=-2.159,P=0.041),FBI-B (9.00(7.00,14.00) vs 7.00(3.00,11.00),Z=-2.051,P=0.040) and HAMD-21 scores (7.00(2.75,14.00) vs 5.00 (3.00,8.00),Z =-2.061,P =0.039).A detail analysis of different cognitive domains showed the executive functions (Z =-2.140,P =0.032),language (Z =-3.357,P =0.001),abstraction (Z =-2.498,P =0.012) and delayed recall (Z =-4.317,P =0.000) of the MoCA scale were lower in FTD patients than that in AD patients,while AD patients had lower scores in memory (Z =-1.999,P =0.046) and orientation (Z =-2.941,P =0.003) of the MMSE scale.Within the subscale scores of the NPI,the agitation (Z =-3.255,P =0.001),disinhibition (Z =-3.093,P =0.002) and irritability (Z =-2.214,P =0.027) scores were higher in FTD patients than in AD patients.The total scores of NPI (r=0.279,P=0.010),FBI (r =0.353,P=0.001),FBI-A (r=0.386,P=0.000) and FBI-B (r =0.273,P =0.012) were positively correlated with the CDR scores,whereas MoCA scores were negatively correlated with the CDR scores (r =-0.760,P =0.000).The subscale scores on MoCA and NPI areas changed corresponding with dementia severity in both groups.Conclusions The cognitive function,behavioral and psychological symptoms between FTD and AD patients are different.FTD patients have poorer executive function,language,abstraction and delayed recall ability,whereas AD patients perform worse in memory and orientation.With the progression of the disease,FTD patients gradually emerged disorientation,while the cognitive impairment in AD patients almost affected all the areas.FTD patients are more likely to have agitation,disinhibition and irritability behavior,and AD patients are more likely to have depression in the late stage.Dynamic evaluation of the cognitive function,behavioral and psychological symptoms in clinical practice can help to distinguish FTD and AD.

BACKGROUND: Tumor necrosis factor-associated protein 1 (TRAP1) is a heat-shock protein 90-related mitochondrial chaperone. Accumulative evidence has demonstrated that TRAP1 overexpression is closely related to carcinogenesis. However, the exact function and mechanism of TRAP1 in the occurrence of laryngeal carcinoma remains unclear. OBJECTIVE: To investigate whether RNA interference can inhibit TRAP1 overexpression and to explore its effects on growth and apoptosis of CD133+CD44+ laryngeal carcinoma stem cells. METHODS: CD133+CD44+ laryngeal carcinoma stem cells were sorted from human laryngeal carcinoma Hep-2 cellsusing immunomagnetic beads. The shRNA sequence of TRAP1 was designed and synthesized and CD133+CD44+ laryngeal carcinoma stem cells were transfected with LipofectamineTM 2000. Cell counting kit-8 assay, colony formation assay and flow cytometry were used to investigate the effects of interference of TRAP1 expression on growth and apoptosis of CD133+CD44+ laryngeal carcinoma stem cells. Spectrophotometric method was used to detect the activity of caspase-3, -8 and -9. RESULTS AND CONCLUSION: TRAP1 mRNA and protein expression levels were significantly decreased in TRAP1 shRNA-transfected CD133+CD44+ laryngeal carcinoma stem cells (P < 0.01). Compared with the blank control and negative control groups, the growth and colony formation of CD133+CD44+ laryngeal carcinoma stem cells were significantly inhibited in the TRAP1 shRNA-transfected group (P < 0.05). Apoptosis of CD133+CD44+ laryngeal carcinoma stem cells was significantly inhibited in the TRAP1 shRNA-transfected group as compared with the blank control and negative control groups (P < 0.05). TRAP1 shRNA-mediated cell apoptosis was associated with the activation of caspase-3, -8 and -9. These results suggest that RNA interference targeting inhibition of TRAP1 suppresses cell growth but promotes apoptosis in CD133+CD44+ aryngeal carcinoma stem cells. TRAP1 is likely to be a gene target for treatment of laryngeal carcinoma.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.
