Abstract
OBJECTIVE To screen the ectodysplasin A (EDA) gene mutation in the patients with non-syndromic tooth agenesis and ectodermal dysplasia, and to analyze the phenotype of missing teeth pattern in these two groups of patients. METHODS In the study, 174 patients with tooth agenesis (143: non-syndromic, 31: ectodermal dysplasia) and 451 health control volunteers were enrolled from the clinic, and the genome DNA was extracted from either peripheral blood or oral mucosal swab. The coding region of EDA gene was then amplified by PCR, sequenced and blasted to online NCBI database. The missing teeth were recorded for all patients, and the missing teeth from patients with EDA mutation were compared among the different dentition sites. RESULTS 33 patients were identified with EDA mutation. In the non-syndromic patients, 13/143(9.09%) were identified with EDA mutation, while in patients with ectodermal dysplasia, 20/31(64.52%) were found with EDA mutation. Ten novel EDA mutations were identified (c.769G>C[p.G257R ],c.936C>G[p.I312M],c.223G>A[p.E75K], .1166C>T[p.P389L],c.133G>C[p.G45R],c.1109G>A[p.E370K],c.914G>T[p.S305I], c.916C>T[p.Q306X],c.602G>T[p.G201V],c.88-89insG[p.A30GfsX69]). For each dentition site there was no statistic difference in the number of missing teeth between the left and right sides, so the number from both sides were combined later in the analysis. In the patients with EDA mutation, the non-syndromic patients had fewer missing teeth (15.9±6.4 missing teeth for each, 207/364 in total) than the patients with ectodermal dysplasia (23.9±4.3, 478/560). In the non-syndromic patients with EDA mutation, the maxillay central incisors and first molars were less affected, with the same missing rate as 19.2% (5/26). While the mandibular central incisors (with a missing rate of 76.9%, 20/26), the maxillary lateral incisors (the missing rate: 88.5%, 23/26), the mandibular lateral incisors (the missing rate: 80.8%, 21/26), and the maxillary first premolars (the missing rate: 80.8%, 21/26) were more likely to be missing. In the ectodermal dysplasia patients with EDA mutation, only maxillary central incisors (the missing rate: 60%, 24/40), maxillary canines (the missing rate: 70%, 28/40), mandibular canines (the missing rate: 67.5%, 27/40), maxillary first molars (the missing rate: 65%, 26/40) and mandibular first molars (the missing rate: 72.5%, 29/40) had higher possibility of persistence. Teeth at other dentition sites were more likely to be affected (the minimum missing rate: 87.5%, 35/40). CONCLUSION The findings would help to reveal the EDA gene and its function in ectodermal organogenesis.

Abstract
OBJECTIVE To compare the clinical efficacy between calcar replacement arthroplasty and InterTan nail in treatment of intertrochanteric fractures in the aged. METHODS From January 2008 to July 2013, a total of 58 elderly patients with intertrochanterie fracture , had been treated in Department of Orthopaedics, Tianjin Occupational Diseases Control and Treatment Hospital, were retrospectively compared.Half of them were treated with calcar replacement arthroplasty and half with InterTan nails.In the calcar replacement arthroplasty group, there were 8 men and 21 women, with an average age of (85.3±4.9) years, there were 8 A1, 16 A2 and 5 A3 fractures according to the AO classification.In the InterTan nail group, there were 10 men and 19 women, with an average age of (86.1±5.6) years, there were 11 A1, 15 A2 and 3 A3 fractures according to the AO classification.The 2 groups were compared in terms of the duration of the operation, intraoperative blood loss, hospitalization time, time of off-bed activity, complications, mortality rate, Harris hip score, short form 36 questionnaire score and ADL score. RESULTS Twenty-seven patients in the calcar replacement arthroplasty group and twenty-six patients in the patients in each group were followed up InterTan nail group were follow-up for a period of 24 months.There were no significant differences between the 2 groups regarding hospitalization time, complications, mortality rate, Harris hip score, short form 36 questionnaire score and ADL score(P>0.05). However, the operative time, intraoperative blood loss, and the time of off-bed activity for the calcar replacement arthroplasty and InterTan nail groups was respectively (78±29) minutes vs (59±32) minutes, (316±185) ml vs (108±97) ml, and (15±5.8) days vs (32±12.7) days, all of them with a significant difierence(P<0.05). CONCLUSION The patients in the calcar replacement arthroplasty group suffered longer operative time and more blood loss, but they can obtain early off-bed activity.The hospitalization time, complications, mortality rate, hip function and quality of Life between the two were the same.

Abstract
Deregulation of cardiac miRNA gene-regulatory networks is a feature of different heart diseases, including ischemic (ICM) and nonischemic (NICM) cardiomyopathy. Here, based on the paired miRNA and mRNA expression profiles in ICM and NICM, we identified the differentially expressed miRNAs and mRNAs and the expression signatures distinguishing ICM/NICM from control samples. Furthermore, we constructed a functional miRNA network for each disease. Analysis of the topological features of these networks revealed that the Wnt signaling pathway and cell cycle (de)regulation play critical roles in the development of ICM and NICM. In addition, comparison of the miRNA and mRNA functional profiles revealed that their expression patterns in ICM and NICM differ. These findings revealed hundreds of novel heart-failure-related miRNAs with important regulatory functions. In summary, RNA-seq-based transcriptome profiling in the failing human heart revealed a complex transcriptional regulation associated with the disease. The newly uncovered importance of miRNAs in disease pathogenesis highlights their value as potential diagnostic and therapeutic targets.

Abstract
The collagen fibre network is an important part of extracellular matrix (ECM) on trabecular bone surface. The geometry features of the network can provide us insights into its physical and physiological properties. However, previous researches have not focused on the geometry and the quantitative description of the collagen fibre network on trabecular bone surface. In this study,we developed a procedure to quantitatively describe the network and verified the validity of the procedure. The experiment proceeds as follow. Atomic force microscopy (AFM) was used to acquire submicron resolution images of the trabecular surface. Then, an image analysing procedure was built to extract important parameters, including, fibre orientation, fibre density, fibre width, fibre crossing numbers, the number of holes formed by fibre s, and the area of holes from AFM images. In order to verify the validity of the parameters extracted by image analysing methods, we adopted two other methods, which are statistical geometry model and computer simulation, to calculate those same parameters and check the consistency of the three methods' results. Statistical tests indicate that there is no significant difference between three groups. We conclude that, (a) the ECM on trabecular surface mainly consists of random collagen fibre network with oriented fibres; (b) our method based on image analysing can be used to characterize quantitative geometry features of the collagen fibre network effectively. This method may provide a basis for quantitative investigating the architecture and function of collagen fibre network.

Abstract
Vibrio parahaemolyticus is a leading cause of food-borne diarrhoea in coastal countries. Although V. parahaemolyticus cases have been reported since 1950, they have been poorly documented. From July 2009 to June 2013, we collected 6951 faecal specimens for pathogen detection; V. parahaemolyticus strains were isolated from 563 specimens (8.1%). We then analysed the characteristics of the 501 V. parahaemolyticus strains that were isolated as the sole pathogen. Twenty-one serotypes were identified among these strains; O3:K6 was the most common serotype (65.1%), followed by O4:K8, O4:K68 and O1:K36. One strain of the O4:K18 serotype was isolated from clinical patients for the first time. Pandemic O3:K6 clones were predominant and accounted for 69.1% of all of the pandemic strains. This is the first report of one strain expressing the O3:K8 serotype with a pandemic genotype. The presence of the haemolysin gene tdh (93.0%) was the key characteristic of the virulent strains; however, a few strains carried the trh gene. We also confirmed the presence of the type III secretion system 2 (T3SS2) genes in all of the pathogenic strains. Subsequent multilocus sequence typing split the isolates into 16 sequence types (STs), with ST3 and ST88 as the most prevalent in southeastern China. Most isolates were sensitive to common antimicrobial agents, apart from ampicillin. However, the resistance rate to ampicillin has apparently increased in this area. In conclusion, our results indicate that pandemic O3:K6 V. parahaemolyticus isolates are predominant in southeastern China, and additional surveillance should be conducted to facilitate control of the transmission of this pathogen.

Abstract
OBJECTIVE To discuss early efficacy of the cardiac patient with giant left ventricle underwent valve replacement. PATIENTS AND METHODS Fifty-five patients, who are suffering cardiac valve disease with giant left ventricle, underwent valve replacement. Among them, sixteen patients underwent aortic valve replacement; thirty patients underwent mitral valve replacement; nine patients underwent double valve replacement. All of them use mechanical heart valve. RESULTS The number of early death after operation was five. Two patients died of malignant arrhythmia; two died of intractable low cardiac output syndrome; the last one's mechanical valve lost its ability to function after operation and died of respiration-circulation failure after an emergency operation. The death rate was 9%. The remaining 55 patients were cured and their cardiac function was significantly improved. CONCLUSIONS The definite effective myocardial protection and perfect and detailed preoperative treatment can reduce the possibility of operative complications and death rate of this kind of patients.
