BK polyomavirus-associated nephropathy (BKPyVAN) is a common cause of allograft failure. However, differentiation between BKPyVAN and type I T cell-mediated rejection (TCMR) is challenging when simian virus 40 (SV40) staining is negative, because of the similarities in histopathology. This study investigated whether donor-derived cell-free DNA (ddcfDNA) can be used to differentiate BKPyVAN. Target region capture sequencing was applied to detect the ddcfDNAs of 12 recipients with stable graft function, 22 with type I TCMR, 21 with proven BKPyVAN, and 5 with possible PyVAN. We found that urinary ddcfDNA levels were upregulated in recipients with graft injury, whereas plasma ddcfDNA levels were comparable for all groups. The median urinary concentrations and fractions of ddcfDNA in proven BKPyVAN recipients were significantly higher than those in type I TCMR recipients (10.4 vs. 6.1 ng/mL,

Objective To investigate the efficacy and safety of patients with malignant pleural effusion treated with injecting endostar combined with platinum complexes into pleural cavity.Methods Cochrane systematic review methods were used in the data selection,and data were selected from the PubMed,Embase,Cochrane Library,China National Knowledge Infrastructure (CNKI),WanFang,and VIP database to get all clinical controlled trials.The retrieval time was August 2014.The objects of these randomized controlled trials were malignant pleural effusion patients.Endostar combination with platinum complexes was used for the experimental group.Platinum complexes alone were used for the control group.The efficacy and adverse effects of two groups were compared.The quality of included trials was evaluated by two reviewers independently.The software RevMan 5.3 was used for meta-analyses.Results Nine trials with 488 patients were included according to the including criterion.All trials were randomized controlled trials,one of them had B level in quality and eight had C level.Meta analysis results were as follows:there was significant difference in overall effective rate (OR =3.52,95% CI =2.37 ~ 5.22),Karnofsky (KPS) score changes rate (OR =2.64,95% CI =1.67 ~ 4.19),between endostar combination with platinum complexes and platinum complexes alone group.The incidences of severe leucopenia (OR =1.0,95% CI =0.62 ~ 1.61) and nausea and vomiting (OR =0.77,95% CI =0.43 ~ 1.38) were similar in the endostar combination with platinum complexes group compared to those in the platinum complexes alone group.Conclusions In the treatment of malignant pleural effusion,injecting endostar in combination with platinum complexes into pleural cavity improves the effective rate without obviously raised side effects.Owing to the small sample size and poor quality of included trials,more well-designed double-blinded randomized controlled trials should be performed.

Objective To observe and contrast the effects of dexmedetomidine and ketamine on the restlessness and analgesia during recovery period of anesthesia after tonsillectomy in children. Methods Sixty ASA Ⅰ-Ⅱ child patients underwent tonsillectomy and adenoidectomy were randomly divided into three groups, group P (appropriate amount of placebo was given in the operation), group D (dexmedetomidine) and group K (ketamine). Data of mean arterial pressure and heart rate of three groups were documented before anesthesia (T0), during extubation (T1), 5 min (T2), 10 min (T3), 15 min (T4) and 30 min (T5) after extubation were recorded. The analepsia time, adverse reactions, restlessness score and pain score were collected in three groups of patients. Results Compared with group P, values of mean arterial pressure and heart rate were more stable at T1, T2 and T3 in groups D and K (P<0.05). The restlessness score, incidence of restlessness and adverse reactions were lower in groups D and K than those in group P (P<0.05), and which were lower in group D than those of group K (P<0.05). Conclusion Both dexmedetomidine and ketamine can play an analgesic role in recovery period of anesthesia and reduce restlessness, adverse reactions and pain score in child patients. Moreover, dexmedetomidine is more effective on inhibiting restlessness and adverse reactions.

Objective To explore the effect of combination therapy of aminoglycosides with other antibiotics on reducing the mutant selective window of Acinetobacter baumannii. Methods Three aminoglycoside antibiotics (amikacin, tobramycin, netilmicin)and four frequently used antibiotics against Acinetobacter baumannii in clinical practice (cefoperazone-sulbactam, imipenem-cilastatin,ciprofloxacin and levofloxacin)were studied.The minimum inhibitory concentrations of these antibiotics against Acinetobacter baumannii ATCC1 9606 were determined by E-test.The mutant prevention concentrations of the four antibiotics against Acinetobacter baumannii alone or in combination with aminoglycosides were determined by agar dilution method.The selective index was calculated. The effect of aminoglycosides on mutant selective window of Acinetobacter baumannii was evaluated according to the change of selective index after combination. Results The selective index of cefoperazone-sulbactam,imipenem-cilastatin,ciprofloxacin and levofloxacin against A.baumannii ATCC19606 was 16,>32, 16 and 32.When combined with amikacin,the selective index was 1,2,4 and 4,respectively.When combined with tobramycin,the index was 2,2,8 and 8,respectively.When combined with netilmicin,the index was 2,4,8 and 16, respectively. Conclusions The mutant prevention concentration of the four antibiotics against Acinetobacter baumannii is significantly reduced when combined with any of the three aminoglycosides,which is helpful to decrease the incidence of mutants and control resistant Acinetobacter baumannii. Amikacin-based combination shows the most evident effect on reducing the mutant selective window of Acinetobacterbaumannii.

Objective To explore the clinical effect of continuous infusion of dopamine and furosemide on elderly patients with refractory heart failure.Methods 76 elderly patients with heart failure were selected as the observation subjects,they were randomly divided into observation group and control group,38 cases in each group.The control group was given oxygen inhalation,the expansion of vascular,cardiac and other conventional treatment.The observation group was given conventional treatment and continuous infusion of dopamine and furosemide.Clinical efficacy and cardiac function improvement were compared between the two groups.Restlts The effective rate of observation group was 92.1%,which was higher than that of the control group (73.7%) (x2 =10.29,P < 0.05).After treatment,the improvement of cardiac function between the two groups had significant difference (t =15.94,10.18,all P <0.05).Conclusion Continuous infusion of dopamine and furosemide in treatment of elderly patients with refractory heart failure could improve heart function,enhance curative effect.

Objective To evaluate the efficacy and safety of linezolid in empirical treatment of methicillin-resistant Staphylococcus (MRS) pneumonia. Methods One hundred and thirty-five hospitalized patients with MSR pneumonia receiving linezolid from April 2009 to October 2010 were enrolled in this retrospective cohort study, and all subjects were assigned to two groups: 75 cases with empirical treatment (linezolid 0. 6 g by infusion q12h at admission) , and 60 cases with objective treatment (linezolid after the sputum culture). The severity score, clinical effect and adverse effect were observed, and the therapeutic effects in patients with high risk factors were especially evaluated. SPSS13.0 software was used for statistical analysis. Results The scores were decreased significantly after finishing therapeutic causes for 3 and 7 days in both groups (tempirical =12.29 and 16.53, tobjective =9.36 and 11.49, P 0.05 ). In the patients with high risk factors, the effective rates of two groups were 86. 8% (33/38) and 63. 6% (14/22) , and the difference was significant (x2 =4.42, P 0. 05). Conclusion Linezolid can be used as empirical treatment for MRS pneumonia with rapid symptoms relieve and high efficacy, especially for patients with high risk.
