Objective To evaluate the clinical significance of the combined determination of serum procalcitonin (PCT),C reactive protein(CRP),prealbumin(PA)and white blood cell(WBC) in curative effect and prognosis of elderly patients with bacterial infection.Methods Serum PCT,CRP,PA and WBC levels and their dynamic changes of 70 patients with bacterial infection from intensive care unit(ICU)were measured.The patients with bacterial infection were classified into serious infection group and local infection group.And the comparison with virus infection group was made.Results The levels of PCT(18.00±3.20)μg/L and CRP(86.17±10.64)mg/L in serious infection group and local infection group[PCT(2.03±0.46)μg/L,CRP(50.24±7.45)mg/L] were increased.The contents of PA were reduced[(3.214±0.88)mg/L,(12.89± 1.03)mg/L].The levels of WBC were increased mildly[(8.89±1.23) × 109/L,(6.54±0.87) × 109/L].The differences were statistically significant between bacterial infection groups(serious infection group and local infection group) and virus infection group [PCT (0.21 ±0.06)μg/L,CRP (5.21 ±0.84) mg/L,PA (20.14 ±2.57)mg/L,WBC (5.30 ± 0.93) × 109/L] (P＜ 0.01).Serum PCT,CRP.PA and WBC showed significant differences between serious infection group and local infection group(P＜0.01).After antibiotic treatment,the levels of PCT (0.5 ± 0.08) μg/L,CRP (10.32 ± 1.65) mg/L and WBC (6.30± 0.91) × 109/L in bacterial infection group were reduced obviously and the concentration of PA (18.19±2.66)mg/L was elevated compared with before treatment [PCT(11.61±8.27)μg/L,CRP (71.80±20.09)mg/L,WBC(7.95± 1.59) × 109/L,PA(7.08±4.87)mg/L] (P＜0.01).Correlative analysis was performed between PCT and others indicators before and after antibiotic treatment in bacterial infection group and virus infection group.There was positive correlation between PCT and CRP,WBC before(r=0.586,0.445) and after treatment (r=0.688,0.463) in bacterial infection group.PCT and WBC(r=0.432) were positively correlated after treatment,while no correlation existed between PCT and others indexes in virus infection group(r＜0.306).When comparing sensitivity and specificity of PCT and CRP for diagnosis of bacterial infection disease,the sensitivity (95.7％) of PCT was similar to that of CRP.The specificity of PCT(86.7％) was remarkably higher than that of CRP(73.3％).Conclusions The combination of serum PCT,CRP.PA and WBC is valuable for early diagnosis of bacterial infection disease.Monitoring PCT level dynamically would assist an evaluation of curative effect and disease outcome of elderly patients.

AIM: To investigate the effects of fenofibrate on angiotensin Ⅱ ( AngⅡ)-induced cardiomyocyte hypertrophy .METHODS:Primary neonatal cardiomyocytes were pretreated with fenofibrate (10μmol/L) for 1 h followed by stimulation with AngⅡ(100 nmol/L).The mRNA levels of ANF, BNP andβ-MHC were measured by real-time PCR. Western blotting was employed to determine the nuclear translocations of NFATc 4 and p65-NFκB.Co-immunoprecipitation was used to investigate the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes .In addition, the DNA binding activity of NFATc4 on the BNP promoter was determined by EMSA .RESULTS:Fenofibrate significantly inhibited AngⅡ-induced cardiomyocyte hypertrophy .Fenofibrate treatment inhibited the nuclear translocations of NFATc 4 and p65-NFκB, as well as the interactions of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes induced by AngⅡ.Fenofi-brate inhibited the binding activity of NFATc 4 with the BNP promoter , which was strengthened by AngⅡ.CONCLU-SION:Fenofibrate enhances the interaction of NFATc 4 with PPARα, decreases the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes , and inhibits the DNA binding activity of NFATc 4 induced by AngⅡ, which may be the important mechanisms of fenofibrate on inhibiting cardiac hypertrophy .

Objective To investigate the effect of recurrent patella dislocation by grafting dual-bundle semitendinosus to anatomically reconstruct of medial patellofemoral ligament(MPFL)under arthroscopy.Methods From January 2006 to January 2010,29 cases(31 knees)with recurrent dislocation of the patella were performed arthroscopic surgery,including 11 males and 18 females(20 knees)with an average age of 22 years(range,16-32).The key point of surgery was reconstruction MPFL with dual-bundle free autogenous semitendinosus by using two anchors and bone groove to fixed on the patella,and using the interference screw to fixed on the femur.Adjusting the patella reset under arthroscopy.Tibial tubercle were transferred to inside in 5 cases.All patients were followed up for an average of 14 months(ranging 9-22).The imaging evaluation included congruence angle,lateral patellofemoral angle and lateral shift.The clinical therapeutic effect was evaluated with International Knee Documentation Committee(IKDC),Lysholm and Tegner scores.Results The fear test was negative after operation.There was no redislocation and fracture of the patella during follow-up.The congruence angle,lateral patellofemoral angle and lateral shift were 5.65°±2.23°,3.52°±2.63° and 0.25±0.46 respectively at the final follow-up.The mean IKDC,Lysholm and Tegner scores were 93.20±5.33,93.02±6.08 and 6.58±0.87 respectively at the final follow-up.All were showed statistically significant differences compared with preoperation(P＜0.05).Conclusion It is demonstrated that there was a reliable short-term effect to treat recurrent patella dislocation by grafting dual-bundle semitendinosus to anatomically reconstruct of MPFL under arthroscopy.

Objective To investigate the expression of a proliferation-inducing ligand (APRIL) in urothelial carcinoma tissue and its clinical significance. Methods We investigated the expression of APRIL mR-NA in urothelial carcinoma tissue of 33 patients in urothelial carcinoma in Cangzhou Central Hospital from July 2013 to March 2015, Among of them, 23 cases of adjacent pericancerous tissues were detected by qRT-PCR. Immunohistochemistry and western blot were used to detect the APRIL protein expression level in urothelial carci-noma tissue and adjacent pericancerous tissues. We analyzed the relationship between APRIL expression and clinical pathology in patients with urothelial carcinoma by statistical methods. Results The qRT-PCR revealed that the expression of APRIL in urothelial carcinoma tissue was significantly higher than that in the adjacent peri-cancerous tissues (P < 0.05). Immunohistochemistry and western blot showed that the expression of APRIL in urothelial carcinoma tissue was higher than that in the adjacent pericancerous tissues. Correlation analysis found that the high expression of APRIL in urothelial carcinoma tissue was not significantly related to gender , age , size of tumor, lymph node metastasizing or not, and clinical stages (P > 0.05). Conclusion The APRIL is a high abnormal expression in urothelial carcinoma tissues , and maybe related to the occurrence and development of urothelial carcinoma.

Methyl parathion hydrolase (MPH, E.C.3.1.8.1) coding gene mph from Pseudomonas sp. WBC-3, isolated and identified by our lab, was successfully expressed in E. coli AD494 (DE3)/ pET32a(+) system as soluble fusion form at high level. The recombinant MPH showed nearly 4～5 fold higher specific activity to parathion than the enzyme from Pseudomonas sp. WBC-3. In addition, the thermal stability of the recombinant enzyme was improved comparing with the wild type enzyme.
