OBJECTIVETo investigate the cost-effectiveness of fish oil in patients undergoing major surgery and those with systemic inflammatory response syndrome(SIRS).
METHODSA retrospective study was conducted in patients undergoing major surgery and those with SIRS on admission in the Zhongshan Hospital from January 2008 to December 2011. Fish oil group was enrolled and matched to control group by 1:2 for gender, age, diagnosis, and surgical procedure. There were 220 pairs of patients who were not admitted to ICU, 102 pairs of patients admitted to ICU, and 66 pairs of patients with SIRS. The clinical outcomes and costs were measured and cost-effectiveness analyses were conducted.
RESULTSThe clinical outcomes and costs showed no significant difference between the fish oil group and the control group in those patients who were not admitted to ICU(P>0.05). Fish oil fat emulsion supplementation significantly reduced the length of total hospital stay, postoperative hospital stay, ICU stay, re-operation rate, infection rates, perioperative mortality in patients admitted to ICU and those with SIRS(P<0.05). The cost-effectiveness ratio of non-reoperation rate, non-infection rate, and survival rate were lower in those patients receiving fish oil fat emulsion as compared with those without fish oil administration. Fish oil fat emulsion supplementation could reduce cost-effectiveness ratios of non-reoperation rate, non-infection rate and survival rate by 105 RMB, 160 RMB, and 89 RMB respectively in major surgical patients who admitted to ICU, and by 670 RMB, 280 RMB, and 220 RMB respectively in SIRS patients.
CONCLUSIONSAddition of fish oil fat emulsion to clinical nutrition may have positive effects on critically ill patients. It seems that the effects of fish oil fat are strongly related to the severity of patient's underlying disease. Fish oil fat emulsion supplementation shows acceptable cost-effectiveness ratio and pharmacoeconomic value.

From air bacteria capable of decomposing creatinine, three single independent strains K9510、K9511 and K9512 have been isolated. The highest creatinine amidohydrolase (EC 3. 5. 2. 10; creatininase) producing strain K9510 was screened out. The strain K9510 was identified as Pseudomonas sp. The results of culture condition for creatininase formation by strain K9510 were obtained as follows: creatinine and creatine were found to be the effective inducers for enzyme formation; the solution of mixed metallic salts could stimulate cell growth and enzyme formation. The suitable medium for creatininase formation was consisted of 0. 9% creatinine、0. 15% yeast extract、 0. 09% malt extract、0. 05% NH4Cl and some amount of the solution of mixed metallic salts at pH5 5. When the bacterium was grown in 250mL conic flask containing 50mL of the medium mentioned above on the rotary shaker(250r/min) at 35℃ for 33 h, about 50 u creatininase was obtained.

ObjectiveTo analyze therapeutic effects of conservative treatment and the causes of malunion of intertrochanteric fracture in elderly patients, and try to find the way to deal with the problems. MethodsFifteen cases aged 75 to 101 years with intertroehanterie fracture treated conservatively were included.Their average age was 88.8 years.All fractures were classified according to Evens-Jensen.Because of the medical complication or other reasons, they were conservatively treated by methods of traction, wearing shoes et al. X-ray examination was taken at regular time and their final functions were assessed. ResultsTwo cases were died 1-3 months after admission, and the fractures were only partially healed. The remaining thirteen cases got complete healing. Among the fifteen cases, the deformity did not happen in 4 cases of IA without fixation and 1 case of IIB with bone traction. All others got the deformity of varus, shorting and external rotation in different degree, which interfered the lower extremity motor function. ConclusionsThe fracture position not kept and fixed satisfactorily during treatment would lead to more joint deformity and deteriorated hip joint function for the displaced intertroehanterie fractures in elderly patients.

In Taiwan, the first human-infecting H6N1 avian influenza virus was isolated in 2013. To better understand the origin, evolutionary relationship and pathogenesis of the H6N1 virus, we studied the adaptive evolution and evolutionary dynamics of the hemagglutinin (HA) genes of the H6N1 virus in Taiwan. We felt that such studies woud contribute to the further study and control of the virus. Datasets were gained from the Flu and Global Initiative on Sharing All Influenza Data (GISAID) databases. Then, phylogenetic trees and evolutionary dynamics were reconstructed. The evolutionary rate and characterization of adaptive evolution were analyzed by bioinformatic methods. Results indicated that the HA genes of H6N1 in Taiwan were divided into at least five types, and that the new types that the infected human H6N1 belonged to could be local advantage type at present. Evolutionary dynamics revealed the viral population expanded first at the end of 1971, reduced sharply in 2008, and then increased slightly. Three sites were identified under positive selection, suggesting that various sites might increase the adaptive ability of the virus. Eighty-nine sites were under negative selection, revealing that these sites might play an important role in the replication and epidemiology of the virus. Interestingly, site 329 upstream from the cleavage site was also under negative selection, suggesting that this site might be associated with the virulence of H6N1. These data suggest that the HA genes of the Taiwanese H6N1 virus have been undergoing adaptive evolution, and that an outbreak may occur again. Hence, more attention should be paid to the identified sites, to enable timely monitoring and control of a future epidemic.
