Objective To identify the expression differences of mircoRNA-29 b (miR-29b),microRNA? 24 (miR-24) and microRNA-200 c (miR-200c) in plasma of infants with primary congenital glaucoma (PCG) and normal,and analyze its clinical significance.Methods The expression quantity of microRNAs (miR-29b,miR-24,miR-200c) in plasma of PCG group (16 cases) and normal control group (49 cases) were detected by RT-PCR,and the relationship between their expression differences and severity of disease were analyzed.The diagnostic value of miRNAs for PCG was evaluated by receiver-operating characteristic curve (ROC).Results The expression quantity of miR-29b,miR-24,miR-200c in PCG group (0.31 ±0.19,0.17 ±0.16,0.55 ±0.18,respectively) were significantly lower than those in normal control group (1.18-±0.52,2.86 ±2.65,1.62 ± 0.76,respectively) (all P ＜ 0.05);The expression quantity of miR-24 and miR-29b in plasma was related to the severity of PCG,the more severe the disease,the lower the expression;ROC curve indicated that miR-24 and miR-29b had a higher diagnostic value for PCG disease than miR-200c.Conclusion Free miRNAs in plasma may be used as a new plasma markers for auxiliary diagnosis of PCG.

Objective:To explore the clinical application in urinary system stones of the inspection technologies intravenous pyelography (IVP),computer tomography urography (CTU) and magnetic resonance urography (MRU). Methods:We collected 100 cases of urinary system stones on which 80 were carried out to IVP,60 to CTU and 35 to MRU,25 patients were implemented all 3 examinations. CTU and MRU are reconstructed with multi-level reorganization (MPR),curved projection reproduction (CPR),volume reproduction (VR) and the maximum intensity projection (MIP). Results:Stones were found in 73 patients of the 80 people by IVP,the diagnosis rate is 91.3 %. Stones were found in all the 60 patients except 1 by CTU with images direct and accurate,the diagnosis rate was 98.1 %. By the MRU,stones were found in 20 of the 35 patients at a display rate of 57.1 %,with images displayed in a low stone location signal,filling defect and the hydrocele circs of renal pelvis and ureter. Conclusion:IVP is a simple method,easy-to-patient acceptance and has a high detection rate of stones; CTU has a good image quality and the detection rate is higher than the stone IVP. By combining with the original cross-sectional image,the rate of diagnosis is up to 98%; as a non-invasive and no contrast agent approach,MRU is also very important in the diagnosis of stones.

Objective To explore the value of endoscopic mini-incision greater saphenous vein harvesting for coronary artery bypass operation. Methods A total of 411 patients scheduled for coronary artery bypass operation were given either endoscopic vein harvesting(EVH Group,n=136) or open vein harvesting(OVH Group,n=275),based on patient's willingness.The operation outcomes and incision complications were compared between the two groups. Results The incidence of various incision complications was significantly lower in the EVH Group(18.4%,25/136) than in the OVH Group(36.7%,101/275)(?~2=14.406,P=0.000).As compared with the OVH Group,the EVH Group had lower incidences of edema(1.5% vs 35.3%;?~2=56.861,P=0.000),paraesthesia(7.4% vs 33.8%;?~2=33.937,P=0.000),hematoma(16.2% vs 27.3%;?~2=6.214,P=0.013),and incisional liquefaction(0.7% vs 8.7%;?~2=10.174,P=0.001) of the lower extemity.The total operation time were 226.3?28.5 min in the EVH Group and 224.7?19.2 min in the OVH Group,without significant difference between the two groups(t=0.673,P=0.502).Early graft failure happened in 1 case in each of the groups,without significant difference between the two groups(?~2=0.000,P=1.000).The numbers of distal coronary anastomoses were 3.6?0.8 in the EVH Group and 3.3?1.0 in the OVH Group,with significant difference(t=3.049,P=0.002). Conclusions Endoscopic greater saphenous vein harvesting can significantly reduce the morbidity associated with incision complications,whereas does not prolong the operative time,increase the incidence of early graft failure,and decrease the number of distal coronary anastomoses.

We developed a three-dimensional finite element model of the shoulder glenohumeral joint after shoulder arthroplasty including humerus shaft, scapular, scapular cartilage and eight muscles, while each of the muscles was simulated with 50 spring elements. To reduce the element number and improve the analytical precision, we used mixed tetrahedral and hexahedral elements in the model. We then used the model to calculate the biomechanics of the shoulder glenohumeral joint after hemiarthroplasty during humeral external rotation. Results showed that the maximum joint reaction force was 374.72 N and the maximum contact stress was 6. 573 MPa together with the contact areas at 40 degrees external rotation. These might be one of the reasons for prosthetic disarticulation, and would provide theoretical bases to prosthetic design.

[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P＜0.01),as well as higher diabetic nephropathy incidence (P＜0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 ％ CI 1.195-3.586).

OBJECTIVETo study the correlation between the Th1/Th2 balance in the peripheral blood and Pi-Wei damp-heat syndrome (PDS) in chronic gastritis (CG).

METHODSFifty-one patients with CG of PDS were recruited, including 22 cases with predominant damp (PDS-D), 9 case with predominant heat (PDS-H), and 20 case with simultaneous onset of damp and Heat (PDS-DH). Besides, 10 healthy volunteers were recruited as the healthy control group. H. pylori (HP) infection was detected by fast urea enzyme, and the expressions of Th1 type cytokines interferon-gamma (IFN-gamma), interleukin-12 (IL-12), and Th2 type cytokines interleukin-4 (IL-4), interleukin-10 (IL-10) in serum were detected by luminex technology.

RESULTSThe HP infection rate was 41.18% (21/51) in the PDS patients, obviously higher than that in the healthy control group (10.00%,1/10), showing statistical difference (P<0.05). The HP infection rate was 45.45% (10/22) in PDS-D, 22.22% (2/9) in PDS-H, and 45.00% (9/20) in PDS-DH. The HP infection rate in PDS-D and PDS-DH was significantly higher than that of the healthy control group, showing statistical difference (P<0.05). There was no statistically significant difference in the expressions of peripheral blood IFN-gamma, IL-12, IL-4, and IL-10 between the PDS patient group and the healthy control group (P>0.05). But the expressions of IFN-gamma and IL-12 showed an increasing trend in the PDS patient group, while the expression of IL-4 showed a decreasing trend. The expressions of IFN-gamma, IL-12, IL-4, and the ratios of IFN-gamma/IL-4 and IL-12/IL-4 were also higher in PDS-DH group than in the PDS-D group and the PDS-H group, but with no statistical significance (P>0.05).

CONCLUSIONThe occurrence of Pi-Wei damp-heat CG was possibly correlated with the imbalance of Th1/Th2. Damp and heat pathogen might be important pathogenic factors leading to Th1 type cytokine immunoreaction.

To explore the relationship between neutrophil-lymphocyte ratio (NLR) and microangiopathy in type 2 diabetes mellitus,303 type 2 diabetic patients were divided into non-microangiopathy (N),diabetic nephropathy (DN),diabetic retinopathy (DR),and DN combined with DR (DNR) groups.The clinical and biochemical data were collected for comparing the differences in NLR among four groups.The results showed that NLR,white blood cell count,neutrophil count in DN,DR,and DNR groups were significantly higher than that in N group,and NLR in DNR group was higher than those in DN and DR groups (3.35 ± 1.35 vs 2.05 ± 0.68 and 1.89 ±0.60,both P＜ 0.05).However,the lymphocyte count in DNR was lower than that in other three groups.The multifactor logistic regression analysis showed that NLR was a risk factor for predicting microangiopathy in type 2 diabetic patients(OR=6.643,95％ CI3.502-12.601,P＜0.01).
