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 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 study experienced doctors’ treatment of senile dementia based on association rule. Methods Databases, such as CNKI, CSCD, CBMdisc, CPD, and Wanfang Data were searched for articles about senile dementia. SPSS17.0 and Clementine12.0 software were used for frequency and correlation analysis of prescription. Results In total of 67 articles about TCM therapy for senile dementia were included, containing 112 prescriptions, 178 Chinese herbal medicines, 1589 frequency, and 14.2 entries for each prescription. The first three frequently used herbal medicines were Acori Tatarinowii Rhizoma, Polygala Radix, and Salviae Miltiorrhizae Radix et Rhizoma. Accoring to association rule, the first three medicine pairs were Citrus Reticulatae Pericarpium→Pinelliae Rhizoma, Dioscoreae Rhizoma→Rehmanniae Radix Praeparata, and Codonopsis Radix→Citrus Reticulatae Pericarpium. The first three thriple herbal medicines were Dioscoreae Rhizoma+Lycii Fructus→Corni Fructus, Acori Tatarinowii Rhizoma+Corni Fructus→Rehmanniae Radix Praeparata, and Carthami Flos + Hirudo→Bupleuri Radix. Conclusion The results based on association rule effectively summarized all the doctors’ treatment experience in senile dementia, and provided the beneficial reference for the clinical treatment of senile dementia.

Objective To investigate the clinical effect of forced-air warming system combined with infusion heating technology on recovery quality and cellular immune.Methods Fifty patients scheduled for esophagus cancer resection randomized into two groups (n =25 each):the temperature protection group (group W)and the control group (group C).The intraoperative nasopharyngeal temperature was recorded before induction (T1 ),2 hours after operation (T2 ),the end of operation (T3 ),postoperative 2 hours (T4 ).The anesthesia wakening time,the occurrence of postoperative shivering and infection,hospitalization time were also recorded.Venous blood samples were taken at T1 ,T3 ,two days (T5 )and five days after the operation (T6 )for analysis of T-lymphocyte subsets by flow cytometry.Results Compared with T1 ,the nasopharyngeal temperature was significantly de-creased at T2 ,T3 and T4 in group C, and the nasopharyngeal temperature in group W was significantly higher than those in group C at T2 ,T3 and T4 (P <0.05).The anesthesia wakening time and the occurrence of postoperative shivering in group C was significantly more than those in group C (P <0.05).Compared with T1 ,the percentage of CD4 + cells and CD4 +/CD8 + ratio were significantly decreased and the percentage of CD8 + cells increased in both groups at T3 (P <0.05).Compared with group C at T3 ,the percentage of CD4 + cells and CD4 +/CD8 + ratio were significantly increased and the percentage of CD8 + cells decreased in group W (P <0.05).Conclusion The clinical use of forced-air warming system combined with infusion heating technology can protect the patient??s body tempera-ture,shorten the anesthesia wakening time,reduce the occurrence of postoperative shivering,which protects the patient??s immune function and accelerates recovery after surgery.

Objective To explore the effects of Shenfu injection combined with low-dose hydrocortisone on plasma lev?els of human leukocyte antigen (HLA)-DR and procalcitonin (PCT) in patients with septic multiple organ dysfunction syn?drome. Methods A total of 118 patients with septic multiple organ dysfunction syndrome were divided into three groups:control group (n=39), experimental group 1 (n=39) and experimental group 2 (n=40). The control group received conventioanl medicine therapy, while the experimental group 1 received Shenfu injection (100 mL, 2/d, for 7 d) combined with conventio?anl medicine therapy, and the experimental group 2 received Shenfu injection combined with low-dose hydrocortisone (200 mg/d, for 14 d) besides conventional medicine therapy. The peripheral blood samples were collected for the detection of HLA-DR, PCT and lipoperoxide (LPO) before treatment, 1 d, 3 d amd 7 d after treatment. The mortality in 14 d was record?ed. Results The mortality rates in 14 d were 61.5%(24/39), 41.0%(16/39) and 25.0%(10/40) for control group, experimen?tal group 1 and experimental group 2 (χ2=8.15, P<0.05). There were no significant differences in PCT, HLA-DR and LPO levels before treatment and 1 d after treatment between the three groups (P>0.05). The plasma levels of PCT and LPO were significantly decreased in control group, experimental group 1 and experimental group 2 after 3-d and 7-d treatment, but the levels of HLA-DR was significantly increased (P < 0.05). Conclusion The combination therapy of Shenfu injection and low-dose hydrocortisone can effectively reduce PCT level and increase HLA-DR level, which promotes the improve?ment of patients with septic multiple organ dysfunction syndrome.

Objective To investigate the clinical efficacy of ultrasound-guided and nerve stimu-lator-guided modified fascia iliaca compartment block combined with popliteal fossa sciatic nerve block in patients undergoing unilateral great saphenous varicose veins surgery.Methods Sixty patients, male 32 and female 28,aged 42-76 years,ASA Ⅰor Ⅱ,scheduled for unilateral great saphenous var-icose veins surgery were randomly divided into two groups (n =30 each):modified fascia iliaca com-partment block with popliteal fossa sciatic nerve block group(group N)and epidural anesthesia(group E).Firstly,popliteal fossa sciatic nerve block was performed in group N.Then confirmed iliac fascia and femoral nerve position on the ultrasonic image and the femoral nerve was blocked.The 1% lido-caine 10 milliliters and 0.5% ropivacaine 10 milliliters were injected in the fascia iliaca compartment block from medial border of sartorius to upward site of femoral artery.Meanwhile,the ultrasonic probe was moving inside in the level of inguinal ligament.The SBP,DBP and HR were recorded be-fore block(T0 ),10(T1 ),30(T2 )and 60 minutes(T3 )after block.The block working time and onset time of sensory block,use of ephedrine after anesthesia,anesthesia efficacy and the postoperative ad-verse reactions in the last 48 hours ,including nausea,vomiting,headache and urinary retention, were also recorded.Results Compared with T0 ,the SBP and DBP was significantly decreased at T2 in group E(P <0.05).Compared with group E at the same time,the SBP and DBP was significantly higher at T2 in group N(P <0.05).The onset time of sensory block was significantly shortened and the use of ephedrine after anesthesia was also less in group N(P <0.05 ).Group E was better than group N in the whole anesthesia efficacy (P <0.05),but there was no significant difference in the ex-cellent rate of anesthesia efficacy between the two groups.The incidence of postoperative urinary re-tention was significantly decreased in group N(P <0.05)and there was no significant difference of the rate of nausea,vomiting and headache.Conclusion Modified fascia iliaca compartment block with popliteal fossa sciatic nerve block has excellent anesthetic quality in patients undergoing unilateral great saphenous varicose veins surgery,which ensures more stable hemodynamics less side effects and more indications when compared with epidural anesthesia.

Objective To compare the antioxidant activity between phenolic and nonphenolic alkaloids in Nelumbo Nucifera Gaertn.in vitro. Methods DPPH, ABTS, hydroxyl radical scavenging, super oxygen anion from oxidation, reducing power and beta carotene bleaching test methods were used to evaluate the antioxidant activity of the alkaloids. Results Half maximalinhibitory concentration ( IC50 ) of DPPH among total alkaloid, phenolic alkaloids and nonphenolic alkaloids was 21.89, 27.10 and 32.87 μg·mL-1 , respectively;IC50 of ABTS free radicals was 14.25, 20.55, 25.94μg·mL-1;The hydroxyl radical scavenging IC50 was 0.03, 0.03, 0.08 μg·mL-1; The auto-oxidation rate of super oxygen was 8.72×10-4, 5.87×10-4, 6.68× 10-4;The total alkaloid had the best reducing power, while the non-phennolic alakloids had the worst; Lipid inhibition rate of three alkaloids were 89.63%, 85.85% and 83.78% respectively. Conclusion Phenolic alkaloids are better than non-phenolic alkaloids in hydroxyl radical scavenging, reducing power and anti-lipid peroxidation, resulting in a promising prospect.

To explore the diagnostic values of miRNA141 and miRNA375 for prostate cancer.The expressions of miRNA141 and miRNA375 in serum samples from 30 prostate cancer (PCA) patients,40 benign prostatic hyperplasia patients and 50 normal controls were detected by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).The expression of miRNA141 in tissue samples from prostate cancer was 13.4±7.2 folds of that from benign prostatic hyperplasia while the expression of miRNA375 in tissue samples from prostate cancer was 28.4 ± 10.3 folds of that from benign prostatic hyperplasia.The differential expression of miRNA141 and miRNA375 in sera of prostate cancer suggested that miRNA141 and miRNA375 might be potential tumor markers in clinical practice.
