Primary lymphoma of bone (PLB) refers to non-Hodgkin lymphoma (NHL),which is an uncommon extranodal lymphoma,accounting for 1 % of all NHL,5 % of extranodal lymphoma and 7 % of primary bone tumor. Currently,the diagnostic criteria of PLB includes a primary focus in a single bone; positive histological diagnosis; and no evidence of distant soft tissue or distant lymph node involvement. The diversity,hereditery,and lower incidence of PLB make it difficult to diagnose. In order to decrease the rate of misdiagnosis and missed diagnosis,the clinical,pathological,and imaging characteristics of PLB in this study are analyzed.

Objective To investigate the effect of glycated albumin on recurrent cerebral infarction in elderly patients with diabetes mellitus. Methods All of 252 elderly acute cerebral infarction patients with diabetes mellitus were chosen from clinics. They were divided into 2 groups: A group ( glycated albumin <19.0% , 117 patients) and B group ( glycated albumin ≥ 19.0%, 135 patients). The clinical characteristics and the recurrent rate of cerebral infarction were compared between two groups. Results The levels of glycated albumin, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol and triglycerides in B group were significantly higher than those in A group:(21.00 ± 4.93)%vs. (16.75±1.72)%, (9.84 ± 2.89) mmol/L vs. (5.36 ± 1.00) mmol/L, (5.44 ± 1.30) mmol/L vs. (4.57 ± 1.00) mmol/L, (3.13±0.81) mmol/L vs. (2.58 ± 0.74) mmol/L, (2.34 ± 1.61) mmol/L vs. (1.74 ± 1.47) mmol/L, P<0.01 or<0.05. The recurrent rate of cerebral infarction in B group was significantly higher than that in A group: 53.3%(72/135) vs.36.7%(43/117), χ2 = 6.946, P = 0.008. Logistic regression analysis showed that the increase of glycated albumin was the independent risk factor of recurrent cerebral infarction in elderly patients with diabetes mellitus (P=0.048). Conclusions The recurrent rate of cerebral infarction is increased in elderly diabetes patients with high glycated albumin. The increase of glycated albumin is the independent risk factor of recurrent cerebral infarction.

Oceanic carbon monoxide(CO) has been of biogeochemical interest due to its significant role in global carbon cycle and the greenhouse effect. A headspace method coupled with ta3000 trace gas analyzer system for the determination of CO in seawater was developed. The effects of temperature, equilibrium time and water/gas volume ratio on the sensitivity of headspace analysis were studied in detail. The results showed that CO concentrations in seawater were measured successfully by the 50-mL glass-only syringes with a water/gas volume ratio of 44∶ 6 and an equilibrium time of 5 min at 20 ℃ room temperature. Under the optimized conditions, the linear range of concentrations of CO was 0-2.7×10~(-6), r=0.999,p<0.0001. The relative standard deviation of the analysis method was <4.4%, with a detection limit of 0.02 nmol/L. The average recovery of CO was 90.5%. The concentrations of CO in surface waters of the North Yellow Sea were measured using this method and ranged from 0.20 nmol/L to 3.13 nmol/L, indicating that this method can be successfully applied to the detection of the in situ CO concentrations in seawater.

Background:Myopathy due to smooth muscle cells( SMC)abnormalities is involved in the pathogenesis of diabetic gastroparesis(DGP),however,the relationship between myopathy and advanced glycation end products(AGEs)is not fully clarified. Aims:To investigate the ultrastructural changes of gastric SMC in patients with diabetes mellitus( DM)and the relationship between expressions of contractile proteins and AGEs. Methods:Full-thickness gastric specimens from 30 gastric neoplasm patients undergoing gastrectomy from July 2012 to December 2012 at the First Affiliated Hospital with Nanjing Medical University were collected. Of them 15 patients had DM( DM group)and the other 15 patients without ( control group). Ultrastructure of SMC was observed by transmission electron microscopy. Expressions of three contractile proteins[ myosin heavy chains( MHC),α-actin and calponin]and Nε-carboxymethyllysine( CML),the key component of AGEs in gastric muscular layer were determined by Western blotting,and expressions of MHC,α-actin and calponin mRNA were determined by real-time PCR. Correlations of mRNA expressions of three contractile proteins with protein expression of CML were analyzed by Pearson correlation coefficient. Results:In DM group,significant ultrastructural changes were found in gastric SMC,including disruption of gap junction,swelling of mitochondria,occurring of lipofuscin in cytoplasm,increase in cell membrane alveolae,and thickening of basal lamina. Protein and mRNA expressions of muscular MHC,α-actin and calponin were significantly lower in DM group than in control group(P all ﹤0. 01),while protein expression of CML was significantly higher in DM group(P ﹤0. 01). In gastric muscular layer of DM group, negative correlations were found between expressions of MHC,calponin mRNA and CML protein(r= -0. 59,P=0. 02;r= -0. 63,P=0. 01),but no correlation was seen between α-actin mRNA and CML protein(r= -0. 49,P=0. 06). Conclusions:Disruption of SMC ultrastructure,decrease in contractile proteins and increase in AGEs are existed in gastric muscular layer of DM patients,and there is a negative correlation between contractile proteins and AGEs. These changes may cause impaired contractility of SMC,and subsequently lead to gastric motility disorders in diabetic patients.

OBJECTIVE:To treat chronic bone defects using particle gun containing BMP2 gene eukaryotic expression plasmid via local injection.
METHODS:A total of 72 healthy New Zealand white rabbits were applied to establish chronic bone defect model in the rabbit radius. According to the length of bone defect, the rabbits were divided into three groups:1.5 cm group, 2.0 cm group, 2.5 cm group. Each group was further randomly assigned into two subgroups:treatment group (BMP-2 gene transfection) and control group (natural y healing). X-ray examinations were performed at 1, 3, 8 and 9 weeks after transfection, and soft tissue between the bone defects was harvested to detect BMP-2 using western blot analysis;and radius specimens were taken for gross observation at the same time points, to evaluate the healing.
RESULTS AND CONCLUSION:(1) Gross specimen observation:bone cal us formation in treatment group was general y more than that in control group. (2) Lane-Sandhu X-ray score in treatment group was significantly higher than that in control group at 1, 3, 8, 9 weeks after transfection (P<0.05). (3) BMP-2 concentration in treatment group was significantly higher than that in control group at each time point (P<0.05). The local transfer of particle gun-mediated BMP-2 gene is an effective therapy of chronic bone defect.
