Objective To investigate the change of plasma cholinesterases (CHEs) in the people with diabetes or fatty liver or overweight , and explore the role of CHE in these diseases .Methods The plasma CHEs in 2834 subjects were detected , and these subjects were divided into five groups , including diabetes , fatty liver , overweight , diabetes with fatty liver , and the normal groups . Results The plasma CHE activities in diabetes group , fatty liver group , overweight group , and diabetes with fatty liver group were all higher than the normal group [(8943 ±1896)U/L, (9716 ±1673)U/L, (8798 ±1710)U/L, (9385 ±1687)U/L vs (8028 ±1621) U/L], and the CHE level in the fatty liver group was highest among five groups .However, the CHE level in diabetes group or fatty liv-er group was not significantly different from that in the diabetes with fatty liver group .The CHE level of the people with components of metabolic syndrome (MS) was significantly higher than that without MS component [(8786 ±1514)U/L, (9141 ±1771)U/L, (9705 ±1628)U/L, (9138 ±1768)U/L, (9530 ±1607)U/L vs (7821 ±1324)U/L]),but the CHE level was not increased gradually with the increased MS component.The plasma CHE had a negative correlation with age ( P =0.00),but it had a positive correlation with triglyceride (TG), total cholesterol (TC), and body mass index (BMI)( P =0.00).Conclusions The plasma CHE activity was el-evated in diabetes group , fatty liver group , and overweight group , which might be a risk factor in these diseases .Controlling the plas-ma CHE might help to treat the metabolism diseases .

Objective:To investigate the effects of 5-aza-2′deoxycytidine(5-aza-dC),a DNA methyltransferase (DNMT)inhibitor, on the methylation status of the RECK gene and the invasion of salivary adenoid cystic carcinoma cell lines.Methods:Methylation-specific PCR,Western blot analysis and quantitative real-time PCR were used to investigate the methylation status of RECK gene and the expression of RECK mRNA and protein in SACC cell lines.The invasive ability of SACC cells was examined by transwell assay. Results:Promoter methylation was only found in ACC-Mcell line and not in ACC-2 cell line.Treatment of ACC-Mcells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression level of mRNA and pro-tein of RECK,suppressed ACC-Mcell invasive ability.Conclusion:5-aza-dC can inhibit ACC-Mcell invasion by reversal of hyperm-ethylation status of RECK gene.

Objective To analyze the surgical treatment of hemangioma of limbs complicated by Kasabach-Mcrritt phenomenon in children.Methods A retrospective study was carried out on 31 children with hemangioma of limbs complicated by Kasabach-Merritt phenomenon.Lower limbs were affected in 19 patients,and upper limbs in 12 patients.Twenty-six patients showed decreased platelet count ((2.6-60) × 109/L) and fibrinogen level (＜ 1 g/L),and 21 prolonged partial prothrombin time (＞ 50 seconds).All the patients who had responded poorly to medications including glucocorticoids received surgical treatment.Results Of these patients,30 were cured,and one died of massive blood loss.After surgical treatment,the platelet count returned to normal in 1-3 days in 25 patients,3-7 days in 4 patients,and more than 10 days in one patient.Conclusions For pediatric hemangiomas of limbs complicated by Kasabach-Merritt phenomenon,surgical treatment should be given as early as possible so as to reduce mortality in patients.

Rats receiving unilateral nigral injection of 6 OHDA resulted in distinct reduction of DA (-88% ) , DOPAC(-80%) and HVA(-60%) in striatum of lesioned side, and the contents of 5HT and 5HIAA remained almost constant in comparison with that of contralateral striatum, suggesting selective lesion of nigrostriatal dopaminer-gic pathway induced by 6OHDA. Following 6OHDA lesion the rats exhibited circling behaviour after APO challenge. 1-Stephaniae ( 1-STP ) significantly antagonizied the action of APO in circling model in dose-dependent manner. Our results indicate that 1-STP possesses the ability to block DA receptor of central nervous system.

OBJECTIVETo explore the therapeutic effect of radiofrequency ablation for tongue venous malformation( VM).

METHODSFrom July 2013 to July 2014, 30 cases with tongue VM (local or diffuse) were retrospectively analyzed. 23 cases underwent radiofrequency ablation treatment. The radiofrequency electrode tip(0. 5 mm in diameter) was inserted into the lesion 1 mm below the bottom with 25 W in power and 15-30 s of pulse. The treatment was repeated when the electrode tip was removed back every 1 mm. Multi-point treatment was performed.

RESULTS15 cases with unilateral VM were completely healed after one-stage radiofrequency ablation. 8 cases with bilateral VM received two-stage radiofrequency ablation with a 3-6 months of interval. Among the 8 cases, completely healing was achieved in 5 cases, partial VM residue happened in 3 cases due to its diffuse lesion and reservation of tongue function. 23 cases were followed up for 3 month to 1.5 years. Good cosmetic and functional results was achieved in 20 cases with no relapse. Partial VM residue was left in 3 cases.

CONCLUSIONSRadiofrequency ablation can effectively treat tongue VM with minimal morbidity and good cosmetic appearance. It also avoids the disadvantages of surgery.

Objective To evaluate the prognostic value of the extracapsular spread (ECS) of regional lymph nodes in nasopharyngeal carcinoma (NPC) based on magnetic resonance imaging.Methods A retrospective review was performed for 477 previously untreated patients with NPC who were treated in Yuebei People′s Hospital from January 2009 to December 2013.Univariate and multivariate survival analyses were performed to identify the prognostic value of ECS in NPC.Results There were 216 patients with ECS and 261 patients without ECS,and the median survival of the two groups of patients was 38.5 months and 39.0 months,respectively.The 3-year overall survival (OS),progression-free survival (PFS),local recurrence-free survival (LRFS),and distant metastasis-free survival (DMFS) rates of the patients with ECS versus those without ECS were 81.9% versus 90.7%,65.8% versus 85.0%,87.8% versus 95.8%,and 80.3% versus 92.9%,respectively (all P=0.000).The univariate analysis showed that N stage and ECS were important prognostic factors for OS,PFS,LRFS,and DMFS in NPC patients (P=0.000-0.004),and T stage and TNM stage were associated with OS,PFS,and DMFS (all P=0.000).The multivariate analysis using the Cox regression model showed that T stage was an independent prognostic factor for the survival of NPC patients,and ECS was an important prognostic factor for PFS,LRFS,and DMFS.Conclusion ECS of regional lymph nodes is a risk factor for local recurrence or distant metastasis in patients with NPC.

Objective To summarize the features of multislice spiral computed tomography (MSCT) examination of gastrointestinal stromal tumors (GISTs),and investigate the relationship between predictors and risk of MSCT examination for GISTs.Methods The clinical data of 110 patients with GISTs who were admitted to the Tianjin Medical University Cancer Institute and Hospital from July 2011 to February 2014 were retrospectively analyzed.All the patients received 64-slices spiral CT (64S-SCT) or 16-slices spiral CT (16S-SCT) scan,and the data were transported to the PACS work station for multiplanar reconstruction.All the tumor samples were collected during operation and diagnosed by morphological manifestation and immunohistochemistry of tumors.Very low,low,and medium risk of GISTs were regarded as lower risk grade,and high risk of GISTs as high risk grade.The univariate analysis and multivariate analysis about features of imaging and risk were done by chi-square test and multivariate logistic regression model.Results Tumors located at the stomach in 81 cases,small intestines in 26 cases and colorectum in 3 cases.Diameter of tumors was 0.8-25.0 cm.Smaller tumors were in round or oval shape with well demarcated boundary,and larger tumors were irregular with unclear boundary.Endo-luminal growth of lessions was detected in 25 cases,duplex growth in 35 cases and extra-luminal growth in 50 cases.Enhanced CT scan showed that most of tumors in 105 patients demostrated moderate and high enhancement,heterogeneous enhancement in 74 cases,low density sacvariable necrosis area without enhancement in 60 cases and superficial,cracked-like and deep ulcer without calcification,metastasis and ascites in 23 cases.According to the features of GISTs by MSCT examination,location of tumor,diameter,shape,boundary,growth,enhancement,cystic necrosis,ulcer and metastasis were risk factors affecting risk classification of tumors by univariate analysis (x2=7.442,49.966,31.513,46.038,13.836,16.626,23.489,8.280,6.811,P ＜0.05).Diameter of tumor more than 10 cm and ulcer were independent risk factors affecting risk classification of tumors by multivariate analysis (OR =9.927,0.070 ; 95％ confidence intewal:1.888-52.180,0.012-0.398,P ＜ 0.05).Conclusion There is a characterization in the location,diameter,shape,boundary of tumor,growth,enhancement,cystic necrosis,ulcer and metastasis,and diameter of tumor more than 10cm and ulcer are independent risk factors affecting the risk classification of GISTs.

ObjectiveTo validate a modified HEART [History, Electrocardiograph (ECG), Age, Risk factors and Troponin] risk score in chest pain patients with suspected non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in the emergency department (ED).Methods This retrospective cohort study used a prospectively acquired database and chest pain patients admitted to the emergency department with suspected NSTE-ACS were enrolled. Data recorded on arrival at the ED were used. The serum sample of high-sensitivity cardiac Troponin I other than conventional cardiac Troponin I used in the HEART risk score was tested. The modified HEART risk score was calculated. The end point was the occurrence of major adverse cardiac events (MACE) defined as a composite of acute myocardial infarction (AMI), percu-taneous intervention (PCI), coronary artery bypass graft (CABG), or all-cause death, within three months after initial presentation.Results A total of 1,300 patients were enrolled. A total of 606 patients (46.6%) had a MACE within three months: 205 patients (15.8%) were diag-nosed with AMI, 465 patients (35.8%) underwent PCI, and 119 patients (9.2%) underwent CABG. There were 10 (0.8%) deaths. A progres-sive, significant pattern of increasing event rate was observed as the score increased (P < 0.001 byχ2 for trend). The area under the receiver operating characteristic curve was 0.84. All patients were classified into three groups: low risk (score 0–2), intermediate risk (score 3–4), and high risk (score 5–10). Event rates were 1.1%, 18.5%, and 67.0%, respectively (P < 0.001).ConclusionsThe modified HEART risk score was validated in chest pain patients with suspected NSTE-ACS and may complement MACE risk assessment and patients triage in the ED. A prospective study of the score is warranted.

Objective To investigate the relationship between lipid fluctuations of daily diet and insulin resistance in patients with type 2 diabetes mellitus(T2DM) with normal fasting lipid profile. Methods One hundred and ninety?eight cases patients with T2DM who were treated in the Endocrinology Department of the General Hospital of Benxi Iron and Steel Group Corporation from October 2012 to September 2014 were selected. Patients were divided into three groups according to fasting and postprandial 4 h triglyceride( TG4 h)
level,the group with normal fasting TG and normal TG4 h with 38 cases,the group with normal fasting TG and rising TG4 h with 78 cases,the group with rising fasting TG and rising TG4 h with 82 cases. The control group was composed of healthy volunteers with 20 cases. The patients followed daily diet habits to eat,blood glucose, insulin and lipid level of fasting and 2 h,4 h after lunch were monitored. Homeostasis model insulin resistance index( HOMA?IR) was used as an index to evaluate insulin resistance,and the correlation analysis was carried out with fasting and dietary intake of postprandial lipid metabolism. Results (1)HbA1c,FPG,HOMA?IR,TG and insulin level in the patients of the group with normal fasting TG and normal TG4 h,the group with normal fasting TG and rising TG4 h,the group with rising fasting TG and rising TG4 h were higher than the control group (HbA1c:(8. 4±1. 9)%,(8. 2±2. 4)%,(7. 8±1. 8)% vs. (4. 3±0. 6)%);FPG:(8. 98±1. 93) mmol/L, (8. 62±1. 33) mmol/L,(8. 28±1. 26) mmol/L vs. (4. 82±0. 63) mmol/L;,HOMA?IR:11. 07±0. 11,6. 98 ±0. 08,3. 83±0. 09 vs. 1. 24±0. 16;TG:0 h TG:(2. 35±1. 85) mmol/L,(1. 60±0. 41) mmol/L,(1. 58±0. 46) mmol/L vs. (0. 82±0. 25) mmol/L;2 h TG:(3. 97±2. 96) mmol/L,(2. 98±1. 49) mmol/L,(1. 83±0. 62) mmol/L vs. (1. 22±0. 31) mmol/L;4 h TG:(4. 24±1. 57) mmol/L,(3. 15±1. 63) mmol/L,(1. 92±0. 53) mmol/L vs. (1. 16±0. 24) mmol/L;insulin(0 h insulin:(26. 51±3. 65) mU/L,(18. 18±6. 24) mU/L,(10. 31 ±2. 38) mU/L vs. (5. 87±1. 62) mU/L;2 h insulin:(59. 15±8. 34) mU/L,(43. 75±9. 83) mU/L,(34. 27 ±1. 61) mU/L vs. (25. 24±1. 98) mU/L;4 h insulin:(51. 22±6. 79) mU/L,(40. 06±7. 51) mU/L,(31. 06 ±1.77) mU/L vs. (13.36±1.37) mU/L;P<0.05). (2)WHR(0.90±0.08 vs.0.72±0.06),HOMA?IR, insulin level of fasting and 2 h,4 h after lunch,TG of 2 h,4 h after lunch in the group with normal fasting TG and rising TG4 h were higher than the group with normal fasting TG and normal TG4 h ( P<0. 05 ) . ( 3 ) BMI ((27. 3±3. 3) kg/m2 vs. (23. 1±1. 5) kg/m2),WHR(0. 96±0. 10 vs. 0. 72±0. 06),HOMA?IR,TG and insulin level of fasting and 2 h,4 h after lunch in the group with rising fasting TG and rising TG4 h were higher than the group with normal fasting TG and normal TG4 h( P<0. 05) . HOMA?IR,TG and insulin level of fasting and 2 h, 4 h after lunch in the group with rising fasting TG and rising TG4 h were higher than the group with normal fasting TG and rising TG4 h( P<0. 05) . ( 4) HOMA?IR was positively correlated with BMI,WHR,and fasting TG levels in the groups with diabetes(r=0. 297,0. 376,0. 326,P<0. 05). HOMA?IR was significantly positively correlated with TG of 2 h,4 h after lunch in the groups with diabetes( r=0. 529,0. 693,P<0. 05) . HOMA?IR was significantly positively correlated with BMI and WHR in the control group(r=0. 617,0. 728,P <0. 05). HOMA?IR was not significantly correlated with fasting and postprandial TG in the control group. Conclusion Postprandial lipid metabolism disorder after daily diet is in some of patients with T2DM with normal fasting lipid profile. Postprandial lipid metabolism disorder after daily diet is significantly positively correlated with insulin resistance in patients with T2DM. Insulin resistance may be one of the pathogenesis of postprandial dyslipidemia in patients with type 2 diabetes.
