Objective To investigate the effect of oxycodone and sufentanil with equivalent dose on hemo-dynamics and stress response in general anesthesia induction. Methods One hundred and twenty ASA I orⅡpa-tients with abdominal surgery were randomly divided into oxycodone group(group O,n=60)and sufentanil group (group S,n = 60). Anesthesia was induced with iv oxycodone 0.20 mg/kg(group O)or sufentanil 0.25 μg/kg (group S)respectively,together with iv propofol 2.0 ~ 2.5 mg/kg and cisatracurium 0.2 mg/kg. The patients were tracheally intubated using a single-lumen endotracheal tube. Mean arterial pressure(MAP),heart rate(HR),plas-ma levels of epinephrine(E)and norepinephrine(NE),cortisol(Cor)and blood sugar(Glu)and the occurrence of bucking before anesthesia induction(T0),immediately before intubation(T1),at the moment of intubation(T2), 1 min(T3)and 5 min(T4)after intubation were observed. Results Compared with these at T0,MAP and HR in 2 groups were lower at T1(P<0.05)and no significant difference was found in 2 groups(P>0.05). MAP and HR were significantly higher at T2 and T3(P < 0.05)and compared with those in group O,MAP and HR in group S were increased more significantly at T2 and T3(P<0.05). MAP and HR increased slightly at T4 in 2 groups but no significant difference was found in 2 groups(P>0.05). Plasma levels of E ,NE,Cor and Glu increased obviously at T2 and T3 in 2 groups(P < 0.05)and they were even higher in group S(P < 0.05). Plasma levels of E ,NE , Cor and Glu increased slightly at T4 in 2 groups but no significant difference was found in 2 groups(P > 0.05). Conclusion Compared with sufentanil ,oxycodone of equivalent dose used for general anesthesia induction can effectively keep smooth on hemodynamics and decrease stress response.

OBJECTIVE:To study the pathogenic organism of sepsis in children with tumor and its drug sensitivity for references of clinical medication.METHODS:The drug sensitivity of hemoculture samples of children with neoplastic hema-tologic disorder was detected by paper disk method.RESULTS:Of the total109pathogenic bacteria isolated from hemoculture samples,60(55.0%)were gram-positive(G + )bacteria,47(43.1%)were gram-negative(G - )bacteria and2(1.8%)were fungi.Vancomycin,teicoplanin and aminoglycosides were more sensitive to G + bacteria,while carbopenems and cefoperazone/sulbactam were more sensitive to G - bacteria.CONCLUSIONS:In treating sepsis in children with tumor,the choice of drugs should be based on the drug sensitivity test,the possibility of G + and G - bacteria infections should be considered in empiric treatment and the possibility of mycotic infection should also be considered after long-term administration of antibacterials.

At present,nutrition therapy plays a very important role in critically ill children,which can impact on the development and outcome of the disease by the process of metabolism and immunity.Immune-modulating nutrients,such as glutamine,which is a current hot topic,but now there is a little research in it in critically ill children,and this paper summarizes the approach,the dose and the efficacy of glutamine in critically ill children,aiming to offer reference in clinics.

Objective To study the relationship between throid hormone and chronic heart failure in patients and its clinical significance. Methods The free thriiodothyronine( FT3 ), the total thriiodothyronine(TT3 ), the free thyroxine(FT4 ), the total thyroxine (TT4 ), the rebellion thriiodothyronine ( rT3 ), the thyroid stimulating hormone (TSH) in 100 patients with chronic heart failure and 50 normal people were determined by particle glimmer. Results The levels of T3 in patients with chronic heart failure were markedly lower than those in normal controls;The heart failure in low thriiodothyronine state case was severe. Conclusion The level of T3 in elderly patients with chronic heart failure was decreased, and it was correlated with the severity of heart failure.

Objective To investigate the role of the clock gene promoter methylation in aging. Methods C57BL mice of 4- (young, n=9) and 20- (old, n=10) month-old were determined the promoter methylation level of clock genes (Per1/2, Bmal1/2, Cry1/2, Clock, Npas2) in the stomach, spleen, vascular, kidney and striatum with methylation-specific polymerase chain reaction (MSP). Results The incidence of promoter methylation of Cry1, Bmal2 and Npas2 in spleen increased in old mice (P<0.05), while the promoter methylation of Per1 in stomach decreased (P<0.05), and the promoter methylation of Bmal1 in vascular increased (P<0.05). Conclusion Promoter methylation of some clock genes is involved in process of aging in a tissue-specific way.

OBJECTIVE: To establish a RP-HPLC method for the simultaneous determination of Protocatechuic acid and Protocatechuic aldehyde in Fuxuekang granules. METHODS: The chromatography was carried on Achirom Bond-1 C18 column(250 mm?4.6 mm,5 ?m). The mobile phase was composed of methanol - water (20∶80,pH=2.80 adjusted by glacial acetic acid) at a flow rate of 1.0 mL?min-1. The detection wavelengths were programmed at 256 nm for Protocatechuic acid and at 280 nm for Protocatechuic aldehyde. RESULTS: The linear ranges for Protocatechuic acid and Protocatechuic aldehyde were 5.49～73.22 ?g?mL-1(r=0.999 9) and 4.81～64.13 ?g?mL-1(r=0.999 9), respectively, and their average recoveries were 96.86%(RSD=2.52%,n=9) and 97.55%(RSD=3.82%,n=9) respectively. CONCLUSION: The method is simple, sensitive, and reproducible, and it is applicable for the quality control of Fuxuekang granules.

Objective To analyze behavioral changes related to HIV/AIDS and trends of HIV epidemic among female sex workers(FSWs),and to provide information for integrated HIV prevention and evaluation of interventions.Methods Continuous surveillance was provided in 41 sites from 2005 to 2007,when cross-sectional surveys were conducted among institution-based and street based female sex workers,and blood samples were faken.Result The rate of using condoms in the last commercial sex activities among the surveyed FSWs was:73.7%,81.1% and 81.5% in the respective 3 years from 2005 to 2007;while the rate of consistently using condoms in sex with clients during the last month was:49.3%,56.4% and 5.4% in the respective 3 years.Female sex workers who had injecting drug use were identified in one third surveillance sites.The rate of awareness of HIV/AIDS transmission among the FSWs was 62.4%,57.3% and 64.8%,respectively.The proportion of the FSWs who attended HIV VCT services was 10.9%,16.6% and 24.9%,respectively.The proportion of the FSWs who received intervention service within the last year was 51.3%,78.8% and 89.8%,respectively.The HIV detection rate was 0.0%(median value)in all the 3 years while the syphilis detection rate was 0.6%,1.0% and 1.15% respectively.Conclusion Rate of condom use and HIV awareness need to be further enhanced among female sex workers.The rate of condom use in the last sex with clients may be over estimated.The proportion of female sex workers who have received intervention service tends to increase;the coverage of behavioral intervention,voluntary counseling and testing and public education is increased gradually.HIV prevalence rate among female sex workers is generally low,but relatively high in some regions.High risk behaviors,such as unprotected sex and injecting drug use are not uncommon among FSWs.All this means that behavioral intervention is a long-term tough task,and to ensure its effectiveness and sustainability integrated HIV/AIDS prevention and control program will be needed.
