Objective To investigate the effect of acute hypervolemic hemodilution(AHHD)on the onset and recovery of muscle relaxation induced by vecuronium.Methods Thirty-two ASA Ⅰ orⅡpatients undergoing elective surgery under general anesthesia were randomly divided into 2 groups(n=16 each):control group and AHHD group.A loading dose of vecuronium 0.1 mg/kg Was given at 10 min after AHHD following tracheal intubatiom The muscular relaxation was maintained at Tl/Tc 5% to 15% by supplement with intravenous vecuroninm.Blood samples were taken at various times during AHHD for chemical analysis.The onset and recovery time of muscular relaxation were recorded.Results Compared with control group ,Hct,Hb and the concentration of TP and Alb were decreased,and the onset and recovery time of vecuronium were shortened in group AHHD(P＜0.05).Conclusion Acute hypervolemic hemodihtion can shorten the onset and recovery of muscle relaxation of vecuronium in patients under general anethesia.

Objective To explore the clinical significance of the brain natriuretic peptide(BNP) in evaluating the cardiotoxicity caused by daunorubicin(DNR) through studying the changes of the plasma BNP levels in children with acute leukemia who accepted the chemotherapy with DNR.Methods Thirty-one children with acute lymphoblastic leukemia(ALL) admitted in the year of 2002-2004 underwent the chemotherapy in DVLP project.The plasma level of BNP was measured by enzyme linked immunosorbent assay(ELISA) and the left ventricular end diastolic diameter(LVEDD) by color Doppler respectively before and after the administration of DNR.Simultaneously,electrocardiography(ECG) and cardiac muscle enzymes(LDH1,CK-MB) were measured as routine.Results The plasma level of BNP increased from(3.97?2.41) ng/L to(18.25?7.63) ng/L(P

ObjectiveTo study the characteristic of apoptosis and the expression of interleukin-1β(IL-1β)and caspase-3, as well as the relation among them after spinal cord injury(SCI) in rats.MethodsAdult SD rats were divided into two groups randomly: sham group and spinal cord injury group. The rats were killed at 1 h, 8 h, 24 h, and 72h after surgery. The expression of IL-1β and caspase-3 was determined with immunohistochemistry and the apoptosis was labeled by TUNEL.ResultsThere was only a few cells that expressed low level IL-1β and caspase-3 in sham group, but they both enhanced in SCI group within 8 h after operation, and then decreased to the level similar to sham group 72 h after operation. The rates of TUNEL-positive cells were similar with that of IL-1β and caspase-3 after SCI. There was positive correlation among expression of IL-1β and caspase-3 and apoptosis index.ConclusionExpression of IL-1β and caspase-3 increase and a large number of TUNEL-positive cells present after SCI in rats, and there is positive correlation among them.

OBJECTIVETo observe the effect of scalp-acupuncture drawing method (SADM) on recovering motor function in hemiplegic patients following cerebral thrombosis at convalescent period.

METHODSAdopting randomized, single-blinded, controlled method, 93 patients suffering from hemiplegia following cerebral thrombosis were randomly assigned to 3 groups, 31 in each group. All patients were treated based on neurological routine therapy, those in the treated group and the control group I were treated respectively with SADM and scalp-acupuncture twirling method (SATM) additionally, but for those in the control group II, no additional treatment was given. The treatment course for all was 4 weeks.

RESULTSBefore treatment, there were insignificant difference among 3 groups in the score of neural motor function deficits (NFDS) of limbs and activity of daily life (ADL) score (P > 0.05). After being treated for 4 weeks, the NFDS was significantly lower and in the control group II (P < 0.01, P < 0.05) and the change of the scores in the treated group was more than that in the control group I (P < 0.05).

CONCLUSIONSADM was superior to scalp-acupuncture twisting prove the ADL score and motor function of hemiplegia patients following cerebral thrombosis in the convalescent stage.

OBJECTIVE:To compare the economics of interferon α1b and α2b in the treatment of chronic hepatitis C. METH-ODS:By retrospective study,114 patients with chronic hepatitis C who received interferon were selected,60 patients received interfer-on α1b were divided into group A and 54 patients received interferon α2b were divided into group B. Negative conversion rate of HCV-RNA,normalization rate of ALT and the incidence of ADR in 2 groups were compared,and pharmacoeconomic analysis was conducted. RESULTS:Negative conversion rates of HCV-RNA in group A in 4,12,24,36,48 weeks were 55.00%,71.67%, 63.33%,61.67% and 65.00%,group B were 64.81%,66.67%,62.96%,55.56% and 61.11%,respectively,there were no signifi-cant differences between 2 groups (P>0.05);after treatment,normalization rate of ALT in group A was 95.23%,group B was 96.10%,there was no significant difference between 2 groups(P>0.05);and there were no significant differences in the incidence of ADR between 2 groups (P>0.05),so cost-minimization analysis was used to evaluate pharmacoeconomics. Therapy cost in group A was 13 216.56 yuan,group B was 7 929.60 yuan,group B was lower to group A;sensitivity analysis received the same results. CON-CLUSIONS:Interferonα2b is more economical thanα1b in the treatment of chronic hepatitis C.

Objective To investigate the prevalence of 16S rRNA methylase gene armA and to analyze their effect on the drug resistance in multi drug-resistant strains of Acinetobacter baumannii . Methods A total of 72 Acinetobacter baumannii isolates were collected from the Second Xiangya Hospital from Jan. 2008 to Dec. 2008. The size of inhibitory zone of these strains to gentamycin, tobramycin and amikacin were determinate using Kirby-Bauer( K-B) method. The 16S rRNA methylase genes armA were detected by PCR. PCR products were purified and sequenced. Then we used randomly amplified polymorphic DNA method (RAPD) genotyping technology for the establishment of DNA fingerprinting. In addition, we compared drug sensitivity test with RAPD technology. Results Twenty isolates of 72 strains were armA positive and the resistance rates of the strains with armA gene to gentamycin, tobramycin, amikacin were 90.0% , 90.0% and 90. 0% , respectivily. armA positive stains were divided into 7 types using RAPD technology. A genotype was the advantage type. Conclusion The study showed that 16S rRNA methylases gene armA was prevalent in Acinetobacter baumannii which could lead to resistant to almost all aminoglycosides at a high level. And the main form of armA gene prevalence in our hospital was the spread of the same clone strain inside and outside of clinic department.
