Objective To evaluate the correlations of serum cardiac troponin T and serum uric acid levels in in aged patients with chronic congestive heart failure(CHF) and the effect of cardiac troponin T(cTnT) on the prognosis of the CHF. Methods 200 cases of congestive heart failure patients(Cardiac function NYHA class Ⅰ-Ⅳ) were enrolled for retrospective analysis and divided into four groups ,50 cases per group;randomly picked 50 cases of pantients with cardiac function NYHA class Ⅰ as a control group; and analyzed the relationship of serum uric (UA) and cTnT level and the occurrence of CHF. All the patients were arranged into normal group and higher group according to cTnT concentration. Cardiac events, including repeated or aggravated heart failure or cardiac death,in patients with increased cTnT during hospitalization were compared to those without it. Results In congestive heart failure group (Cardiac function NYHA class Ⅱ-Ⅳ) ,the cTnT and UA contents increased significantly than that in control group.Incidence of cardiac events was higher in patients with increased cTnT than without it (P ＜ 0.05). Conclusion The heavier the congestive heart failure, the blood uric acid and troponin T were more elevated, so they were closely linked with congestive heart failure, and were the factor for onset of congestive heart failure, and could be combined to evaluate the severity of heart failure in aged patients. The cTnT could predict the prognosis of the old patients with CHF.

Objective To evaluate the diagnostic value of lipoprotein-associated phospholipase A2 (Lp-PLA2) and carotid artery ultra sound for transient ischemic attack (TIA) . Methods Ninety patients with TIA of internal carotid artery system in the acute phase and 55 normal control subjects were recruited. Their carotid intima-media thicknesses were assessed by carotid ultrasonography. Serum Lp-PLA2 levels were determined by enzyme-linked immunosorbentassay(ELISA) ,and all the data were compared between the two group. Results The detection rate of carotid atherosclerotic plaque in the TIA group was significantly higher than that in the control group f 78. 9% (71/90) vs. 29. 1% (16/55), x2 = 35. 27, P < 0.01] . There were 35 carotid atherosclerotic plaque in the control group,of which 6 were unstable plaques and 29 were stable plaques. There were 134 carotid atherosclerotic plaque in the TIA group,of which 103 were unstable plaques and 31 were stable plaques, the constituent ratio of unstable plaque in the TIA group was significantly higher than that in the control group (x2 =43. 22 ,P < 0. 01). The levels of serum Lp-PLA2 in male and female patients in TIA group were ([19. 08 ±7. 92] mol/(min · ml) and [15. 15 ±4. 91] mol/(min · ml),which were significantly higher than those in male and female in the control group ([13. 86 ± 3. 15] mol/(min · ml) and [11. 18 ± 2. 96] mol/ (min · ml) (t = 3. 8598 and 2. 9260, respectively, Ps < 0. 01). Furthermore, the levels of serum Lp-PLA2 of males in the TIA group and control group were significantly higher than that of females in the TIA group and control group(t=2. 3850 and 2. 9143, respectively, Ps < 0.05). The level of serum Lp-PLA2 in unstable plaque patients in the TIA group was (20.16 ± 6. 76) mol/ (min · ml) , which was significantly higher than that in stable plaque patients in the TIA group was (16. 09 ±4. 15)mol/(min · ml) ,the difference was statistically significant (t = 2. 5578, P < 0. 05). Conclusion Serum Lp-PLA2 is a risk factor of carotid atherosclerotic plaque, the combination of Lp-PLA2 and carotid ultrosonography can be used and alert indicator of TIA.

Diabetes mellitus( DM) rates remain highly and is increasing dramatically worldwide. Meanwhile, the incidence of tuberculosis ( TB) decreased slowly. Moreover, DM is an important risk factor for TB incidence. Therefore, TB-DM comorbidity is becoming a new challenge in the field of prevention and control of TB. TB patients complicated with DM displayed distinct pathological manifestations, severity, course of disease, treatment complexity, failure rate of anti-TB treatment, death and recurrence compared with ordinary TB patients. Infection and incidence of TB is closely related to the immune function of the host. For patients with DM or hyperglycemia, the immune function is changed, which leads to the increase of the risk of TB and also affects the condition and prognosis of the disease. The present review summarize the current advances in the study of the immunological characteristics of TB-DM comorbidity, including the changes of both innate and adaptive immune responses, aiming to provide reference for the basic research and prevention and control of TB-DM comorbidity.

Objective To investigate the human papillomavirus (HPV)E6/E7 mRNA detection used in cervical cancer screen-ing.Methods In the study,160 patients treated in gynaecology department of the hospital were enrolled,whose samples were col-lected for ultra-thin liquid-based cytology(thin prep cytology test,TCT).According to the TCT results,the patients were divided into 4 groups,including normal group(n=32),CINⅠ group(n=44),CINⅡ group(n=67),CINⅢ group(n=17).In addition to the CIN classification,according to the type of pathology the patients′groups were also devided.In different groups,the differences be-tween HPV E6/E7 mRNA and HPV DNA positive rate were compared respectively.The differences between HPV E6/E7 mRNA and HPV DNA levels among different pathology groups were also compared.Results In groups of different CIN grades and control group,the positive rate of HPV E6/E7 mRNA and HPV DNA test showed statistically diffrences (P <0.05 ).Compared among different pathologic groups HPV E6/E7 mRNA and HPV DNA levels were statistically significant (P <0.05).Conclusion In cer-vical cancer screening,HPV E6/E7 mRNA screening can be used as a screening method and its combined use with cytological meth-od would be helpful to improve the diagnostic accuracy.

Objective To investigate the distribution and antimicrobial resistance of pathogens causing diabetic foot ulcer(DFU). Methods Secretion specimens of DFU in patients at several hospitals in Qingdao were collected and performed bacterial culture and antimicrobial susceptibility testing. Results A total of 216 pathogens were ob-tained from 137 patients with DFU. Isolation rate of gram-negative bacilli,gram-positive cocci and fungi was 58.80% (n= 127),39.81% (n= 86)and 1.39% (n= 3)respectively. 76 (55.47% )patients were infected with sin-gle pathogen,61 (44.53% )were infected with mixed pathogens;the top five detected pathogens were Pseudomonas aeruginosa(n= 37),Staphylococcusaureus (n= 35),Escherichiacoli (n= 26),Staphylococcusepidermidis(n=24),and Acinetobacterbaumannii(n= 22). The resistance of Enterobacteriaceae to amikacin,amoxicillin/clavu-lanic acid,cefoxitin,imipenem,piperacillin/tazobactam,ticarcillin/clavulanic acid were 0-16.67% ;the resist-ance of Pseudomonas aeruginosa to imipenem,tobramycin,amikacin,cefepime,gentamicin,and quinolones were 2 .70% -1 8 .92% ;the resistance of Acinetobacterbaumannii to imipenem and levofloxacin were low,but to the other antimicrobial agents were all above 30% . Conclusion The major pathogens from DFU were gram-negative bacilli, the next were gram-positive cocci,antimicrobial resistance patterns of each species are quite different,clinicians should choose antimicrobial agents according to antimicrobial susceptibility testing results.
