Objective To investigate the clinical characteristics of elderly patients with multiple myeloma and their prognostic factors.Methods 100 multiple myeloma patients with age≥ 60 years and 100 multiple myeloma patients with age <60 years who admitted in our hospital from December 2007 to December 2015 were collected as research subjects.100 patients with age ≥60 years were divided into elderly multiple myeloma group,100 cases with aged <60 years were divided into non -elderly multiple myeloma group.The clinical data and laboratory results of two groups were compared,the prognosis factors in elderly patients with multiple myeloma were analyzed.Results The incidence rate of ISS stage Ⅰ -Ⅱ in elderly multiple myeloma group (45.0%)was lower than non -elderly multiple myeloma group (60.0%),the incidence rate of stage Ⅲ was higher than non -elderly multiple myeloma group (χ2 =4.511,P <0.05).The infection incidence of elderly multiple myeloma group(30.0%)was higher than non -elderly multiple myeloma group(15.0%)(χ2 =10.452,P <0.05 ).The hemoglobin,serum albumin contents of elderly multiple myeloma group [(83.7 ±19.8)g/L,(27.89 ±6.87)g/L]were less than non -elderly multiple myeloma group[(92.1 ±22.5)g/L,(33.15 ±7.69)g/L](t =4.297,4.426,all P <0.05).The calcium content,the propor-tion of bone marrow plasma cells,serum creatinine and blood β-microspheres protein levels of elderly multiple mye-loma group [(2.51 ±0.41)mmol/L,(39.43 ±18.64)%,(182.24 ±125.47)μmol/L,(9.02 ±6.24)mg/L]were higher than non -elderly multiple myeloma group [(2.36 ±0.48)mmol/L,(37.45 ±19.86)%,(143.25 ± 116.43)μmol/L,(5.87 ±3.41)mg/L](t =5.945,4.196,4.375,4.264,all P <0.05).The median survival time of elderly multiple myeloma patients were significantly correlated with the patients'age,the proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin,and ISS staging (χ2 =4.125,3.254,8.542,5.748,9.244,all P <0.05).Conclusion The condition of elderly myeloma patients is more serious,age,proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin and ISS stage affect myeloma patients prognosis.

Objective To analyze the composition of and drug resistance in bacteria isolated from the lesions of patients with squamous cell carcinoma of the face and head.Methods Lesional tissue or discharges were obtained from 246 patients with squamous cell carcinoma of the face and head,and subjected to conventional bacterial culture.The isolated bacteria were identified by VITEK TWO automated microbiology system.Antimicrobial susceptibility testing was carried out by Kirby-bauer method.WHONET 5.3 software was utilized for statistical analysis.Results Totally,294 bacterial strains were isolated,including 168 Gram-negative bacteria (57.1％)and 126 Gram-positive bacteria(42.9％).The bacterial isolates were predominated by Staphylococcus aureus(21.4％),followed by Escherichia coli(20.4％),Staphylococcus epidermidis(18.4％),Klebsiellapneumoniae(15.4％)and Pseudomonas aeruginosa(9.5％).The prevalence was 40％,26.7％,42.9％ and 55.6％ respectively for extended spectrum β lactamases-producing E.coli and K.pneumoniae,methicillinresistant staphylococcus aureus(MRSA)and methicillin-resistant coagulase-negative S.epidermidis(MRCNS)respectively.P.aeruginosa,E.coli and K.pneumoniae were highly susceptible to imipenem and meropenem,and favorably sensitive to β-lactam and β-1actamase inhibitor combination.No resistance was observed for vancomycin,teicoplanin or linezolid in staphylococci.Conclusions The bacterial isolates from squamous cell carcinoma tissue on the head and neck are predominated by conditional pathogenic bacteria,and the proportion of Gram-negative bacteria is higher than that of Gram-positive bacteria.These isolates seem to be highly resistant to common antibiotics.

Objective To evaluate the diagnostic value of computed tomography enteroclysis/enterography (CTE),magnetic resorance enteroclysis/enterography (MRE) and ultrasonography (US) in Crohn's disease (CD) by Meta-analysis.Methods Segmental intestinal wall thickening and strengthening was taken as image diagnostic indicators in CD.Endoscopic and histopathologic findings and follow-up results were set as diagnostic standard.Retrieve and literature inclusion criteria were developed.The papers of CD diagnosed by CTE,MRE and US which met the criteria were searched and screened.The quality of the papers was evaluated by quality assessment of diagnostic accuracy studies (QUADAS).The diagnostic efficacy of CTE,MRE and US was compared,which included sensitivity,specificity,positive likelihood ratio and negative likelihood ratio,positive predictive value (PPV) and negative predictive value (NPV).Results Among the 2197 retrieved literature,a total of 12 papers met the criteria and nine of which were blinded study.The papers were grouped by three different imaging techniques and underwent QUADAS scale scoring.One paper was about CTE and MRE comparative study,so there were six papers in CTE group,the scores of all the six papers were over 10 and all of them were blinded study.There were four papers in MRE group,the scores of three papers were over 10 and all of them were blinded study.There were three papers in US group,the score of one paper was over 10 and two of these three papers were blinded study and one with unclear evaluation.The sensitivity of CTE group was the highest (89 ％),while the specificity (90 ％) was lower than that of US group (95％).The PPV (93％),NPV (95％),positive likelihood ratio (15.16) and negative likelihood ratio (0.17) of US group were the highest,those of CTE were secondary (PPV 91％,NPV 82％,positive likelihood ratio 6.25 and negative likelihood ratio 0.15).The sensitivity (74％),specificity (84％),PPV (80％),NPV (80％),positive likelihood ratio (4.18) and negative likelihood ratio (0.33) of MRE group were lower than both US group and CTE group.Conclusions The sensitivity of CTE in CD diagnosis is better than that of MRE and US,while other diagnostic indicators are poorer than US.Even though US has high diagnostic value in CD,more well designed large sample study were still needed for further evaluation.

Objective To investigate the antitumor effect of the recombined adeno-associated virus encoding caveolin-1 regulated by progression-elevated gene (PEG) promotor on the angiogenesis of implanted human hepatocellular carcinoma(HCC) cell lines in a nude mouse model. Methods HepG2 cells were inoculated subcutaneously into NOD/SCID mice, and animals were treated with rAAV-PEG-caveolin-1 after tumor cell innoculation. The fluorescence ratio of Evans blue to FITC-dextran was used to assess the changes of microvasculature permeability of the tumor. Western blot and immunohistochemical analyses were employed to detect PECAM-1 expression in tumor microvascular endothelium and microvessel density(MVD), respectively; NOS activity was assessed by citrulline generation. Tumor growth was observed and tumor cell apoptosis in tumor tissues were measured by TUNEL. Results Tumor growth was significantly inhibited in mice injected with rAAV-PEG-caveolin-1. The administration of rAAV-PEG-caveolin-1 significantly blocked vascular leakage in the tumor microcirculation. The levels of PECAM-1 protein detected by Western blot were markedly reduced in rAAV-PEG-caveolin-1-treated mice, and there were fewer MVD in tumors from caveolin-1-treated mice, while NOS catalytic activity was much lower in rAAV-PEG-caveolin-1-treated mice compared to the control and empty vector-treated animals. TUNEL demonstrated significant induction of tumor cell specific apoptosis. Conclusions rAAV-PEG-caveolin-1 can reduce tumor progression through blocking microvascular formation by inhibiting eNOS.

Ultrasonography examinations were performed for carotid atherosclerosis in 548 patients with type 2 diabetes mellitus (T2DM). Blood glucose, glycosylated hemoglobin, total serum bilirubin, uric acid, total cholesterol ( TC ), triglycerides ( TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL) were measured. Total serum bilirubin level in T2DM patients without carotid atherosclerosis was (13.0±7. 1 )μmol/L, while that was (10. 9 ± 4. 9 )μmol/L in patients with carotid atherosclerosis (P ＜0. 01 ). The logistic analysis showed that total serum bilirubin level was negatively related to the presence of carotid atherosclerosis ( P ＜ 0. 05 ), which indicated that higher level of total serum bilirubin might be a protective factor for macroangiopathy in T2DM.

Objective To investigate the methods for repairing skin defects after excision of small cutaneous malignant tumors at the lower one third part of nose and their clinical effects.Methods Lesions of small cutaneous malignant tumors at lower one third part of the nose were removed in 54 patients.Intraoperative pathology was performed to confirm the absence of survival carcinoma tissues after resection.According to the site,size,shape and neighborous skin status of defects,bilobed flaps,two-side rotation flaps and nasolabial flaps were selected to repair nasal skin tissue defects.Results There were 39(72.22%) cases of basal cell carcinoma, 9(16.67%) squamous cell carcinoma, 6(11.11%) keratoacanthoma.Skin defects after tumor removal were situated at the lower one third part of nose in all cases with less than 2.0 cm in diameter.Bilobed flaps were used to repair skin defects in 20 cases.rotation flaps in 2 cases,and nasolabial flap in 32 cases.As a result,all flaps survived and no obvious deformation of nose was observed in these cases.No recurrence occurred in a 5-year follow-up.Conclusion A satisfactory repair of skin defects at the lower one third part of nose with a diameter of less than 2.0 cm is achieved with bilobed flaps,two-side rotation flaps and nasolabial flaps.

Glioma is the most common type of cancer in the brain and central nervous system,mainly originated from glioma cells or neuronal cells.It is characterized by high prevalence,recurrence rate and mortality.Among aggressive brain tumors,the incidence of glioma is the highest.Long non-coding RNA(lncRNA)is one of the most popular non-coding RNAs in tumor research.It has a variety of biological functions and regulates gene expression at the transcription,post-transcription and genetic levels.It was found that lncRNA was abnormally expressed in cancer patients,and abnormally expressed lncRNA was also found in glioma.lncRNA regulates the occurrence and development of gliomas through different signaling pathways,and affects the heterogeneity and invasiveness of gliomas through the glycolytic pathway.In addition,immune-related lncRNAs are valuable in evaluating the diagnosis,treatment and prognosis of gliomas.In this article,the role of lncRNA in glioma will be reviewed from three aspects including regulation of signaling pathway,glycolytic pathway and immunoregulation.
