Alcoholic fatty liver disease (AFLD) is a pathological change of liver steatosis caused by long-term heavy alcohol consumption. The mechanism of AFLD formation mainly includes abnormal lipid metabolism, immune-inflammatory reaction, intestinal flora imbalance, alcohol metabolism enzyme disorder and so on. In recent years, numerous studies have confirmed that microRNA (miRNA) plays an important role in diagnosis and treatment of many diseases, the molecular regulatory mechanism of miRNAs involved in AFLD formation has also become a research focus. The majority of studies have explored the role of miRNAs in AFLD formation by exploring the targeting role of miRNAs of key genes in the formation pathway of AFLD, and establishing an expression network with genes that promote or inhibit the expression of downstream genes of this signaling pathway. In present paper, the important miRNAs in the formation pathway of AFLD and their regulatory mechanisms in AFLD are reviewed, so as to provide theoretical basis for further understanding the function of miRNAs and its relevant mechanisms in AFLD.

Objective To compare 99Tcm-MIBI MPI with delayed enhancement MRI (DE-MRI) in patients with idiopathic dilated cardiomyopathy (IDCM). Methods Forty patients with IDCM were included. They underwent both rest 99Tcm-MIBI myocardial perfusion imaging and DE-MRI within 7 days. 99Tcm-MIBI MPI was performed to identify diffuse or segmental abnormal perfusion patterns including reduced or defect perfusion segments. DE-MRI images were divided into 4 categories: no delayed enhancement, septal, subendocardial and transmural delayed enhancement, x2 test was used for data analysis. Results Diffuse and segmental perfusion abnormality on 99Tcm-MIBI MPI were found in 19 (47.5%) and 21 (52.5%)patients respectively, while DE-MRI enhancement was simultaneously found in 5 patients of the former (5/19, 26.3%) and 18 (18/21, 85.7%) of the latter (x2 =14.401, P＜0. 001). For those (n=18) with both segmental perfusion abnormality and DE-MRI enhancement, the number of segments of the 4 DE-MRI respectively. A significant difference was found in the DE-MRI enhancement categories between normal and defect perfusion segments (x2 = 29. 183, P ＜0.001 ) and between reduced and defect perfusion segments as well (x2 =25. 110, P＜0. 001). Conclusions Both diffuse and segmental perfusion abnormalities on 99Tcm-MIBI MPI can be found in patients with IDCM. DE-MRI enhancement is more frequently found in patients with segmental perfusion abnormality.

OBJECTIVETo compare clinical outcomes of swing shoulder and internal fixation in treating proximal humeral fractures.

METHODSFrom June 2007 to June 2012, totally 89 elderly patients with humeral proximal fractures were treated by swing of shoulder or internal fixation, and 81 patients were followed up. In swing shoulder group, there were 38 patients including 13 males and 25 females aged from 62 to 84 with an average of (67.11±6.18) years old; 27 cases were 2-part fractures and 11 cases were 3-part fractures according to Neer classfication. In internal fixation group, there were 43 patients including 16 males and 27 females aged from 60 to 80 with an average of (66.47±5.48) years old; and 29 cases were 2-part fractures and 14 cases were 3-part fractures according to Neer classfication. VAS score and complications were compared between two groups after treatment, and Constant-Murley functional scoring was used to evaluate shoulder function of patients.

RESULTSEighty-one patients were followed up from 13 to 26 months with an average of 18.3 months. There was no significant difference in preoperative VAS score between two groups. After treatment, VAS score in swing shoulder group was (3.11±0.95), and (3.88±1.14) in internal fixation group, and had significant difference between two groups (t=-3.313,P<0.05). There was no significant difference in Constant-Murley scores between swing shoulder group (79.53±3.73) and internal fixation group (77.98±4.11) (t=1.768,P>0.05). Postoperative complications in swing shoulder group was 18.4%(7/38), 39.5%(17/43) in internal fixation group, and had significant differences between two groups (χ2=4.313,P<0.05).

CONCLUSIONSwing shoulder for the treatment of proximal humeral fractures in elderly has advantages of low cost, less complications and good recovery of joint function; while internal fixation has a good therapeutic effect but increased complications.

OBJECTIVETo study the combination of trans-anal intersphincteric resection and transabdominal total mesorectal excision for anus-retained ultra-low rectal tumors.

METHODSClinical data of 34 ultra-low rectal tumor patients without external anal sphincter involved, who underwent the combination surgery, were retrospectively analyzed.

RESULTSThe distance from the distal incisal margin of the rectum to the inferior margin of the tumor ranged from 1.8 cm to 3.0 cm on an average of 2.1 cm. For pathological types, there were 23 cases of adenocarcinoma (9 well differentiated and 14 moderately differentiated), 1 papillary carcinoma, 2 rectal stromal tumor, 5 rectal villous adenoma with neoplasia and 3 giant villous adenoma. For pathological stages, there were 18 cases at stage pTNM I, 5 at IIA, 1 at IIB, 4 at IIIA, 1 at III and for T grading, there were 15 cases at stage T1, 5 at T2, 8 at T3, 1 at T4. In these 34 patients, there were 3 cases with postoperative anastomotic stenosis, 2 with postoperative anastomotic rupture, 2 with rectovaginal fistula and no operative death. Because of the dysfunction of bowel control, bowel frequency varied from 3 to 12 in the early stage after operation, but with the recovery of anus function, bowel frequency decreased and ranged form 1 to 5 times a day and the time of formed bowel control could be more than 5 min in 6-12 months after operation. However, patients underwent total resection of internal anal sphincter still suffered from incontinence of loose stool after 1 year. After operation, anastomotic recurrence was found in 1 case in 5 months, liver metastasis in 1 case in 10 months and 28 months respectively, cardiac sudden death in 1 case in 26 months.

CONCLUSIONThe combination of trans-anal ISR and trans-abdominal TME for anus-retained ultra low rectal tumor is not only coincident with radical tumor principle but also retains the function of anus, on the premise of the strict indication.

OBJECTIVETo investigate the clinical characteristics of patients with idiopathic pulmonary arterial hypertension (IPAH) in China.

METHODSA total of 161 patients diagnosed as IPAH in Shanghai Pulmonary Hospital from June 2008 to June 2010 were retrospective analyzed.

RESULTSThe mean diagnostic age was (33 ± 15) years old and 70.2% patients were female. The median duration from symptoms onset to diagnostic right heart catheterization was 12 months. Incidence of NYHA class III to IV was 56.5% at diagnosis and the mean six minutes walk distance was limited to (398 ± 108) meters. Incidence of mild obstructive, restrictive and diffusing impairment in pulmonary function test was 7.8%, 42.2% and 82.2% patients with IPAH, respectively. Right heart catheterization demonstrated severe elevated mean pulmonary arterial pressure [(63 ± 17) mm Hg (1 mm Hg = 0.133 kPa)] and pulmonary vascular resistance index [(25 ± 12) Wood U/m(2)] in this patient cohort. The response rate of acute pulmonary vasoreactivity testing was 8.7% in this cohort. Compared with non-responders, responders to acute pulmonary vasoreactivity testing were younger and with less severe pulmonary hypertension. Among non-responders, 89% patients were treated by one specific anti-pulmonary arterial hypertension drug and 27% patients received combined anti-pulmonary arterial hypertension medications.

CONCLUSIONSYoung female was predominantly involved in patients with IPAH in China. The diagnosis of IPAH is often made at advanced disease stage and majority patients with IPAH received specific anti-pulmonary arterial hypertension therapies in this patient cohort.

OBJECTIVETo assess the level of language understanding and expression of healthy children aged from 8 to 16 months in urban Beijing and to investigate the children's physical and psychological development conditions and social and economic status of children's family as to identifying the related factors to children's language development and providing a basis for instructing parents child-rearing and promoting early children language development.

METHODSA quantitative Cross-sectional Study was made. The parents or care givers of 636 healthy young children, randomly stratified and selected in two districts in Beijing were interviewed. T-test was used to compare the scores of language understanding and expression between boys and girls in the same age. Single and multiple factors analysis were used so as to find out the related factors.

RESULTSFor boys, the average scores of language were respectively 115.0 for 8 months, 243.0 for 12 months and 410.6 for 16 months; for girls the average scores were respectively 109.9 for 8 months, 286.4 for 12 months and 456.2 for 16 months. The average score of language understanding of boys was higher than that of girls only in the 11 month group. The average scores of language expression of girls were higher than those of boys in 11, 12, 14, 15 month groups. Multiple factors analysis showed that parent-child book reading, parent-child tape listening, higher education level of grandmothers, children' extroversion personality, child being able to speak one word and children's age were positively related to the children' language score.

CONCLUSIONProviding rich language environment should be helpful to early children's language development.
