OBJECTIVE:To provide reference for clinical application of antibiotics and the management of pathogen. METH-ODS:The clinical isolated bacteria in our hospital from 2011 to 2014 were identified and analyzed,and the amount of antibiotics in our hospital from 2011 to 2014 were analyzed. The operation and result of drug susceptibility test were in accordance with the standard of clinical laboratory standards institute(CLSI),using WHONET software for statistical processing. RESULTS:The main bacteria isolated in our hospital during 2011-2014 were as follows:constituent ratio of Escherichia coli were 14.93%,16.81%, 15.01% and 15.41%,respectively;that of Staphylococcus aureus were 9.84%,11.90%,9.83% and 7.17%,respectively;that of Acinetobacter baumannii were 9.00%, 9.95%, 14.24% and 18.64%, respectively;that of Pseudomonas aeruginosa were 12.36%,12.42%,14.20% and 15.48%,respectively. The main antibiotics used in our hospital during 2011-2014 were as fol-lows:the amount of piperacillin/tazobactam(2.25 g/a)were 4 685,12 610,13 639 and 14 542,respectively;that of cefepime (0.5 g/a)were 8 613,24 738,12 684 and 6 751,respectively;that of aztreonam(0.5 g/a)were 14 124,32 062,3 323 and 4 534,respectively;that of meropenem(0.5 g/a)were 2 291,5 436,6 813 and 5 341,repectively;that of levofloxacin(0.3 g/a) were 12 253,40 893,48 468 and 50 558,respectively. CONCLUSIONS:With the increase of antibiotics,susceptibility rate of main pathogen are gradually decreased;rational use of antibiotics plays an important role in decreasing the drug resistance.

OBJECTIVE:With reference to the principle and experimental method specified by GB/T16886-ISO10993, to fuly and systematicaly assess the biocompatibility of copper-titanium aloy. METHODS:Based on the pre-experimental results, titanium aloy containing 10% copper was selected and subjected to oral mucosa stimulation experiment, skin stimulation test, acute systemic toxicity test, hemolytic test, prothrombin time test and dynamic coagulation test for biocompatibility evaluation. RESULTS AND CONCLUSION:The copper-titanium aloy has no oral mucous membrane irritation, no short-term systemic toxicity, no skin sensitization, and no hemolysis, indicating it has a good biocompatibility.

The authors designed to separate, purify and determine the monosaccharide composition of the polysaccharide from Cordyceps militaris, and study its effect on reverse cholesterol transport in vivo by isotope tracing assay. Polysaccharides were separate and purify by ion exchange column Q-sepharose Fast Flow and size exclusion column Sephacryl S200HR; the molecular weight and monosaccharide composition of the polysaccharides were determined by high performance gel permeation chromatography and high performance liquid chromatography coming with pre-column derivation, respectively. Finally, three purified polysaccharides CMBW1, CMBW2 and CMYW1 were obtained, their total carbohydrate contents were 87%, 89%, 95%, respectively; their protein contents were 6.5%, 1.3%, 2.8%, respectively; their molecular weights were 772.1, 20.9, 13.2 kDa, respectively; CMBW1 was composed of mannose, glucosamine, rhamnose, glucuronic acid, glucose, galactose and arabinose with a molar ratio of 7.25: 0.17: 1.29: 0.23: 6.30: 11.08: 0.79; CMBW2 was composed of mannose, glucosamine, galactose and arabinose with a molar ratio of 2.40: 0.16: 2.92: 0.24; CMYW1 was composed of mannose, glucosamine, glucuronic acid and glucose with a molar ratio of 0.59: 0.57: 0.45: 25.61. Polysaccharide at 50 mg x kg(-1) could significantly improve the transport of 3H- cholesterol to blood and excretion from feces. All of the three purified polysaccharides CMBW1, CMBW2 and CMYW1 were heteropolysaccharide; and they could improve reverse cholesterol transport in vivo, the underlying mechanisms are being studied.

Objective To evaluate the effect of dezocine on the c-fos expression in neurons in the midbrain periaqueductal gray in a rat model of incisional pain.Methods Thirty-six pathogen-free healthy adult male Wistar rats,weighing 250-300 g,were divided into 3 groups (n =12 each) using a random number table:control group (group C),incisional pain group (group I) and dezocine group (group D).A 1 cm longitudinal incision was made through skin,fascia and muscle of the plantar aspect of the right hind paw in sevoflurane-anesthetized rats.In group C,the rats were only anesthetized and underwent no operation.In group I,0.9％ sodium chloride solution 2 ml was injected via the caudal vein at 15 min before the model was established.In group D,dezocine 1 mg/kg (diluted to 2 ml in 0.9％ sodium chloride solution) was injected via the caudal vein at 15 min before the model was established.At 24 h before operation (T0) and 2,6 and 24 h after operation (T1-3),the mechanical paw withdrawal threshold (MWT) and cumulative pain score were measured.After measurement of the pain threshold at T3,the whole brain was removed for determination of the c-fos expression in neurons in the midbrain periaqueductal gray by immunohistochemistry.Results Compared with group C,the MWT was significantly decreased,cumulative pain scores were increased,and the expression of c-fos in neurons in the midbrain periaqueductal gray was upregulated at T1-3 in I and D groups (P＜0.05).Compared with group I,the MWT was significantly increased,the cumulative pain score was decreased,and the expression of c-fos protein in neurons in the midbrain periaqueductal gray was down-regulated at T1.3 in group D (P＜0.05).Conclusion Dezocine mitigates incisional pain through inhibiting the expression of c-fos in neurons in the midbrain periaqueductal gray of rats.

Objective To investigate the effects of music therapy in treating cognitive dysfunction in early stroke patients. Methods Forty patients who had suffered a stroke in the previous four weeks were randomly di-vided into two groups of 20. One received music therapy as part of their cognitive training ( observation group) , and the other did not (control group). Before and after 6 weeks of treatment, cognitive functioning was evaluated using the second Chinese edition of Loewenstein's occupational therapy cognitive assessment (LOTCA). The patients' a-bility in the activities of daily living was also evaluated using the modified Barthel index (MBI). Results After treatment, the total LOTCA and MBI scores in both groups were significantly higher than before. Both LOTCA and MBI scores in the observation group were significantly higher than in the control group, and there were also signifi-cant differences between the observation and control groups on all of the LOTCA sub-items except spatial percep-tion. Conclusions Music therapy can improve the effects of rehabilitation on cognition and the ADL ability of early stroke patients.
