Objective:To evaluate the safety of patient controlled epidural analgesia (PCEA)for elderly patient. Method: Forty two adult patients after operation were divided into control group(44.4?7.8a)and old group(70.9?5.la) according to their ages. All patients reeeived epidural 0.125% bupivacaine and 0.01% morphine mixture for PCEA. BP,HR, RR and SpO_2 were monitored for the first 24 hours following PCEA. Result: The dosage of the mixture was 33.3?6.8ml in control group and 31.6?8.7ml in old group. BP,HR didn't alter markedly in both groups throughout the whole period. RR and SpO_2 remined normal levels. Conclusion: With adequate dosage PCEA can be used safely for elderly postoperative analgesia

Objective: To evaluate the feasibility and safety of postoperative patient-controlled epidural analgesia (PCEA)in children. Methods: Forty postoperative pediatric patients(5-11 years old)were divided into two groups. A and B. Both wereinstituted with postoperative PCEA with LCP model (loading dose 2.05 + 0.13ml), continuos infusion rate 0.82 + 0.15mi/h, PCA dose 0.81 + 0.16ml)by Graseby-9300 PCA pump. The PCEA solution of group A was 0.075% bupivacaine plus0.0012 % buprenorphine, that of group B was same while 0. 005% droperidol was added as an adjuvant. Results:The volumeof PCEA sdution consumption in group B was significantly less than that in group A on the first and second postoperative day (P< 0.01-0.05). Good analgesic efficiency with little side effects was obtained, as evaluated by the VASF emasay or D/D score and complications in two groups, but the analgesic effect of group B was better than that of group A. Conclusion: Thepediatric PCEA with low concentration of bupivaeaine plus buprenorphine is feasible and safe. Droperidol may enhance theanalgesic effects of PCEA.

Objective To study the early and mid-term outcome in terms of left ventricular(LV)geometry and function in patients with transposition of great arteries with intact ventricular septum (TGA/IVS) undergoing arterial switch operation.Methods Twenty patients were followed up and divided into 2 groups according to age:the earlier group and the later group.Age and sexual matched controls were also designed as control group 1 and control group 2.LV posterior wall thickness(PWTd),dimension(LVIDd)and length(L) at end diastolic phase,LV end-diastolic volume (EDV),end-systolic volume (ESV),ejection fraction (EF),mitral valve early (E) and late (A) inflow velocities and E/A,isovolumic relaxation time (IVRT) were obtained by two-dimensional echocardiography,normalized isovolumic relaxation time (IVRTn),wall thickness index (PWTd/LVIDd) and LV geometry index(LVIDd/L) were calculated,and these indexes between groups were compared.Results ①Compared with control group 1,PWTd in earlier group was higher [(0.41 + 0.06)cm vs (0.36 + 0.05)cm,P =0.022],but LVIDd had no significant statistical difference [(2.08 + 0.21)cm vs (2.21 + 0.23)cm,P =0.117],indicating PWTd/ LVIDd differed between groups(0.20 + 0.04 vs 0.16 + 0.01 P =0.001).②No abnormalities were observed in later group.③Compared with different age groups in TGA,EDV,ESV,L,LVIDd,PWTd were significantly higher in later group(P =0.000).There were obvious correlations between EDV,ESV,L,LVIDd and examined age (r =0.90,0.83,0.73,0.90,P =0.000,R2 =0.809,0.694,0.528,0.808) while there were no significant correlation between PWTd and examined age(r =0.56,P =0.000,R2 =0.309).Conclusions Early after operation,LV is undergoing hypertrophy or hyperplasia in TGA/IVS,but will recover in the mid-term period,and the function is normal all the time indicating that the LV myocardium may avoided irreversible pathological changes if operated in time.All in all,LV develops well in mid-term period.

Objective To explore the epidemiological features of the metabolic syndrome in a cohort study of Xiangtan Mengkuang in China.Methods The prevalence rate,means and standard deviation of various risk factors associated with metabolic syndrome were analysed on the basis of base-line survey of risk factors of 5792 subjects(aged 25 years-old～) in 2004.Results (1)The prevalence rate of metabolic syndrome was 12.9%(12.4% in males,and 13.7% in females,P

Objective To observe the effect of Tongfu Xiere Recipe (TXP) combined with routine treatment on cytokine level in patients with acute lung injury due to surgery disease of chest. Methods Fifty eight patients with acute lung injury due to surgery disease of chest were randomized into two groups. The two groups received routine treatment subjecting to the Guideline (2006) for Diagnosis and Treatment of Acute Lung Injury/Acute Respiratory Distress Syndrome. The treatment group additionally received TXP (mainly composed of Radix et Rhizoma Rhei, Natrii Sulfas, Fructus Gardeniae, Caulis Lonicerae, Herba Taraxaci, Semen Raphani, Semen Lepidii seu Descurainiae, Rhizoma Polygoni Cuspidati, Radix Paeoniae Rubra, Fructus Aurantii Immaturus, and Cortex Magnoliae Officinalis) for 5 days or till oxygenation index recovered to the normal. The therapeutic effect was evaluated after treatment, and the changes of blood tumor necrosis factor ? (TNF-?), interleukin 6 (IL-6) and interleukin 8 (IL-8) levels were observed before and after treatment. Results The serum levels of TNF-?, IL-6 and IL-8 in the two groups after treatment were decreased (P0.05). Conclusion The therapeutic effect of traditional Chinese medicine integrated with western medicine is superior to the western medicine only for acute lung injury due to surgery disease of chest. TXP can regulate the immune function and relieve the pulmonary inflammation and injury by decreasing the blood levels of TNF-?, IL-6 and IL-8, thus enhance the therapeutic effect of western medicine.
