Objective To determine and compare the minimum local analgesic concentration(MLAC) of ropivacaine and bupivacaine in continuous block of axillary brachial plexus for postoperative active mobilization of flexor tendon. Methods Seventy ASA Ⅰ or Ⅱ patients undergoing relaxation of flexor tendon were randomly allocated into 2 groups (n = 35 each): ropivacaine group (group R) and bupivacaine group (group B). A catheter was inserted into axillary sheath using B. Braun stimulating intraducer, 24-48 h after operation. 30 min before functional exercise 20 ml of ropivacaine or bupivacaine was injected through catheter. The minimum local analgesic concentration of both local anesthetics was determined by up-and-down sequential test. The first concentration of both local anesthetics was 0.1%. The next concentration of local anesthetic was determined by response of the previous patient. The analgesia efficacy was assessed using 100 mm VAS score (0 = no pain, 100 mm = worst possible pain) . Increase/decrease in VAS by 10 mm was defined as effective. An effective result resulted in increase/decrease by 0.01% in the next patient. The motor block was also recorded.Results The two groups were comparable with regard to age, sex, body weight and baseline VAS score. The MLAC of ropivacaine was 0.133% [95% confidence interval (CI), 0.128%-0.138%] and MLAC of bupivacaine was0.121% (95%CI, 0.116%-0.126%). The analgesic potency of ropivacaine was 10% less than that of bupivacaine. The potency ratio of ropivacaine to bupivacaine was 0.91. The degree of motor block is higher with bupivacaine than with ropivacaine. Conclusion The results of our study show that the analgesic potency of ropivacaine is 10% less than that of bupivacaine. The degree of motor block is higher with bupivacaine than with ropivacaine.

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.

Objective To observe the effect of acute retrograde gastric electrical stimulation (RGES) on gastric accommodation,emptying and gastrointestinal hormones releasing in obese patients. Methods Sixteen obese patients were examined. On the first day,a pair of mucosal gastric electrodes was placed under endoscope. The liquid meal load test and the standard solid meal gastric emptying test were carried out on the second day. RGES was performed starting at 30 minutes before each test and through the whole testing process. The serum leptin,ghrelin,resistin and peptide YY were examined before and after the standard solid meal gastric emptying test. On the third day,sham stimulation was given. The effect of acute RGES on related index was compared by self-control.Results BMI of the 16 patients was (32. 90±2. 99) kg/m2. Acute RGES significantly reduced the liquid meal volume of fullness [(460±148) ml and (630±219) ml,t=-7. 200,P＜0. 01] and the maximal tolerable meal volume [(699±215) ml and (926±295) ml,t=- 5. 390,P＜0. 01]. The effects of RGES and sham RGES on half-emptying time of standard solid meal was (109±26) min and (103±31) min (t=1. 009,P= 0. 329);on the retention rate of standard solid meal at one hour and two hour was (63. 37±9. 75)% and (59. 73±12.87)% (t=1. 834,P= 0. 087),(42.22±13.97)%and (38. 33±16. 87)% (t= 1.780,P= 0. 095),respectively. The ratio of gastrointestinal hormones after and before the stimulation also of the sham stimulation,leptin was 1. 03±0. 34 and 1. 08±0. 38(t=-0.386,P=0. 705),ghrelin was 0. 99±0. 11 and 0. 98±0. 12 (t= 0. 413,P=0.685),resistin was 1. 11±0. 25 and 0. 99±0. 24 (t= 1. 753,P= 0. 100),and peptide YY was 1. 56±0. 71 and 1. 33±0. 61 (t=1. 402,P= 0. 181). Conclusions In obese patients,acute RGES significantly reduce the liquid meal volume by lower gastric accommodation,to certain extent which will delay gastric emptying. There is no significant influence on gastrointestinal hormones releasing.

In this paper, the effect of 5% (V/V) n-alkanes (e.g, n-Heptane, n-Octane, n-Decane, n-Dodecanen-Tetradecane and n-Hexadecane) on the growth and protease production of organic-solvent-tolerant- bacte-rium Bacillus licheniformis YP1 was studied. 5%(V/V) n-alkanes had no effect on the stability of YP1 prote-ase. 5% (V/V) n-alkanes had no notable influence on the yield of strain YP1 but dramatically affected theprotease production. The presence of n-Heptane, n-Octane and n-Decane deeply repressed the protease pro-duction; however n-Dodecane, n-Tetradecane and n-Hexadecane enhanced the protease production promi-nencely. The concentration of n-Tetradecane (1%-8%, V/V) had a direct ration with the protease production.The detailed experiments showed that the notable increase of protease activity appeared at the late logarithmof cultivation compared with the blank. The cell shape of YP1 strain remarkably decreased when grown inthe presence of n-Tetradecane. This is the first report about the effect of n-alkanes on the protease productionby the solvent tolerant bacterium.
