The use of bortezomib in clinic provides a novel method for the treatment of refractory and relapsed MCL. This review summarizes the mechanism and efficiency of bortezomib in the treatment of MCL and the strategies for overcome of bortezomib resistance.

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.

Gene Expression Omnibus (GEO)can act as an international public resource platform storing and sharing experimental data generated from high-throughout research projects that utilize genome-wide expression strategies like microarray screening and analysis.Numerous data involving inflammatory carcinoma models is helpful for dissecting the regulatory network and molecular mechanism of oncogenesis,thus offering favorable clues for new thoughts in prevention and treatment of cancers.GEO originated from various disease models or processed experiments also provides researchers with powerful evidence for tracing functions of novel predictive genes.

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.

Moyamoya disease is a rare cerebrovascular disease.Its incidence is higher in the East Asia.The pathogenesis of MMD remains unclear at present,but the epidemiological research both at home and abroad suggests that the genetic factors play an important role in the onset of MMD.This article briefly reviews the recent progress in research on MMD related genes.

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 investigate the distribution and antimicrobial resistance of pathogens from lower respira-tory tract in patients in intensive care unit (ICU),so as to provide reference for clinical treatment.Methods Distri-bution and antimicrobial susceptibility of pathogens isolated from ICU patients’sputum obtained through fiberbron-choscope between 2011 and 2014 were analyzed retrospectively.Results A total of 3 454 pathogenic strains were isolated between January 1 ,2011 and December 31 ,2014,the percentage of gram-negative bacteria,gram-positive bacteria,and fungi were 84.11 %,14.50%,and 1 .39% respectively.The detection rates of extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella spp .in 2011 -2014 were 38.46% -73.33% and 26.95% -37.06% respectively. Enterobacteriaceae strains had low resistance rates to imipenem and meropenem (<20.00%);resistance of Acinetobacter baumannii was higher than Pseudomonas aeruginosa ,both had low resistance rates to amikacin(3.32%-37.16%);vancomycin-and linezolid-resistant strains were not found among Staphylo-coccus .In 2011 - 2014,detection rates of methicillin-resistant Staphylococcus aureus (MRSA)were 42.86% -61 .22%,methicillin-resistant coagulase-negative staphylococcus (MRCNS)were 86.96% - 91 .67%;resistance rates of Enterococcus faecium was higher than Enterococcus faecalis ,vancomycin-resistant strains were not found among Enterococcus faecalis and Enterococcus faecium ;the major fungus was Candida albicans .Conclusion Anti-microbial resistance of pathogens isolated from lower respiratory tract is getting more serious,clinicians should pay attention to non-antimicrobial infection control strategies in addition to rational use of antimicrobial agents.

Background and purpose:Cervical conization, including high frequency loop electrosurgical excision procedure(LEEP) has been widely used in the treatment of cervical diseases, but how to deal with the patients with pathological positive margin is a problem for clinicians.The purpose of this study was to discuss the option of adjuvant treatment after cervical conization with positive margins for patients with cervical neoplasm.Methods:The data of 528 patients who had cervical conization from 1998 to 2008 was reviewed, among which 54 patients with pathological positive margin was retreated and analyzed.Results:Fifty-four patients were divided into observation group and treatment group, 17 cases were in observation group and 37 cases in treatmeat proup.The recurrence / duration / progress rate was 17.6%(3/17), in treatment group it was 2.7%(1/37) in observation.CINⅠ-Ⅱ positive margins in both group had no recurrence;among 14 patients with CINⅢ, 1 lesion persisted, and 1 progressed to cervical squamous cell carcinoma, none in treatment group was recurrent;For those 10 patients with micro-invasive margin-positive cases, 1 progressed to squamous cell carcinoma, the remaining 9 cases were followed up for 26 months without recurrence after operation.One case in invasive cancer group had recurrence.Conclusion:The patients with CINⅢ margin-positive patients after conization should receive individualized treatment.The patient with microinvasive carcinoma should be retreated with either re-conization or hysterectomy;if with margin-positive CINⅢ after conization, or re-conization or directly treated according to guideline addressing for ⅠB, if margin showed microinvasive carcinoma.The patients with margin-positive invasive carcinoma after conization should be treated according to guideline.
