Objective To evaluate the effect of infiltration anesthesia at Calot's triangle on postoperative analgesia in the patients undergoing laparoscopic cholecystectomy.Methods One hundred and forty patients,aged 18-64 yr,with 18 kg/m2 ≤ body mass index ≤ 31 kg/m2,of ASA physical status Ⅰ or Ⅱ,scheduled for elective laparoscopic cholecystectomy,were randomly divided into 2 groups (n =70 each):control group (group A) and infiltration anesthesia at Calot's triangle group (group B).In group B,1％ ropivacaine 10 ml was injected into Calot's triangle before dissection of the gallbladder,while the equal volume of normal saline was injected into Calot's triangle in group A.The patients in both groups received patient-controlled intravenous analgesia (PCIA) for 48 h starting from 10 min before the end of surgery.The VAS score was maintained below 4 during PCIA.When VAS score ≥ 4,lasting for more than 30 min,tramadol 1.5 mg/kg was injected intravenously.The consumption of physic liquor for PCIA,and requirement for tramadol were recorded.The incidence of puncture-related damage to Calot's triangle and local anesthetic intoxication and adverse effects such as nausea and vomiting within 48 h after surgery were also recorded.The first postoperative flatus time was recorded.Results Compared with group A,the consumption of physic liquor for PCIA,requirement for tramadol,and consumption of tramadol were significantly reduced,and no significant change was found in the incidence of nausea and vomiting and the first postoperative flatus time in group B.No puncture-related damage to Calot's triangle occurred in A and B groups.There was no local anesthetic intoxication in group B.Conclusion Infiltration anesthesia at Calot's triangle can optimize postoperative analgesia in the patients undergoing laparoscopic cholecystectomy.

There are many subjects related to anesthesiology and the band between anesthesiology and clinical practicevery is close. So students can not be proficient in anesthesiology by traditional teaching methods. The use of three-dimensional case teaching method in anaesthesiology teaching is a good attemptment. three-dimensional case teaching method integrate case method, multimedia technology and clinical case. It can help medical students analyze and solve clinical problems, improvetheir academic performance and enhance their clinical basic skills.

Objective To explore advantages of simulation-based medical education for overseas students on training of anesthcsia emergency skills.Methods twenty eight oversea students accepting anesthesia practice course were divided into two groups,each group fourteen.The students of simulation group (group S) were lectured with simulation-based medical education method,while the students of control group (group C) were lectured with tradition education method.Results the practice examination record and satisfaction degree for teaching in group S were both higher than that in group C (P＜0.05).Conclusion The simulation-based medical education was better than tradition education method on training of anesthesia emergency skills for oversea students.The simulation-based medical education may raise the learning interest of oversea students obviously,and it is beneficial to students' mastery of practice skills.

ObjeCtive To investigate the value of protein biochip in the diagnosis of Lyme borreliosis. Methods The serum IgM and IgG antibodies against flagellin were detected by flagellin coated-and N-hydroxysuccinimide (NHS) modified-biochips in 82 patients with neuroborreliosis (NB),35 patients with erythema migrans (EM) and 44 normal controls.The results were compared with those from enzyme-linked immunosorbent assays (ELISA) and Western blot.Results The levels of both IgM and IgG antibodies were significantly higher in the NB patients than those in the normal controls (P

Objective To investigate the effect of triiodothyronine on the expression of alpha subunit of C protein Co (Coa) gene in cultured rat cerebral cortex neurons. Methods Primary cultured neurons of rat were prepared from the cerebral cortex at embryonic day 19. The neurons were cultured in DMEM supplemented with 15% fetal calf serum. After 7 days, the neurons were cultured in different media; DMEM supplemented with 15% fetal calf serum (group A), DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group B), 0.5nmol/L T3-containing DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group C) , 5nmol/L T3-containing DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group D) and 50nmol/L T3-containing DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group E). The neurons were cultured for another 7 days and total RNA was extracted. Goa mRNA leves were measured by competitive RT-PCR. Results As compared with group A, Coa mRNA leves in group B, D and E were low (P 0.05). Conclusion T, has dual effects on the expression of Coa gene in cultured rat cerebral cortex neurons. T3 down-regulated Coa mRNA in cultured neuron. However, in the absence of T3, Goa mRNA was also very low. Thyroid hormone may exert their action on brain development by regulating the the expression of Goa gene.

Objective To investigate the effect of propofol anesthesia on electroconvulsive therapy (ECT)-induced hyperphosphorylation of Tau protein in hippocampus in depressed rats.Methods Thirty-two female WYK rats in which the total score was 30-120 after Open-field test,aged 24 weeks,weighing 200-250 g,were randomly divided into 4 groups ( n =8 each):control group (group C),propofol group (group P),ECT group (group E)and propofol + ECT group (group PE).In groups C and E,the animals received intraperitoneal normal saline 5 ml,and in addition the animals received ECT 15 min later in group E.In groups P and PE,the animals received intraperitoneal 100 mg/kg propofol 5 ml,and in addition the animals received ECT 15 min later in group PE.The learning and memory function was assessed by Morris water maze test at 24 h after ECT.The animals were sacririced at 6 h after Morris water maze test and the hippocampal tissues were removed for determination of the expression of phosphorylated Tau protein.Results Compared with group C,the escape latency was significantly prolonged,the swimming time was significantly shortened in groups P,E and PE,the expression of phosphorylated Tau protein in hippocampus was down-regulated in group P,and the expression of phosphorylated Tau protein in hippocampus was up-regulated in group E ( P ＜ 0.05).Compared with group E,the escape latency was significantly shortened,the swimming time was significantly prolonged,and the expression of phosphorylated Tau protein in hippocampus was down-regulated in group PE (P ＜0.05).Conclusion The mechanism by which propofol anesthesia improves cognitive impairment induced by ECT may be related to inhibition of hyperphosphorylation of Tau protein in hippocampus in depressed rats.

Objective To investigate the effects of different doses of propofol on expression of synaptophysin (SYP) mRNA and protein in the hippocampus of mentally depressed rats after electroconvulsive therapy (ECT) .Methods Fifty adult male SD rats weighing 200-250 g were randomly divided into 5 groups (n = 10 each): group Ⅰ control (group C); group D mental depression (group D) ; group Ⅲ , Ⅳ , Ⅴ propofol 90, 110, 130 mg/kg + ECT (group M_1, M_2, M_3). Mental depression was induced by isolation and chronic unpredictable mild stress (CUMS) in group Ⅱ-Ⅴ . Group M_1 , M_2 and M_3 received intraperitoneal (IP) propofol 90, 110 and 130 mg/kg respectively + ECT once a day ×7 consecutive days while group C and D received IP normal saline instead of propofol. The rats underwent open field test and sucrose liquid consumption test the day before and after mental depression was established and one day after treatment. The rats were killed after the last test for determination of expression of SYP mRNA (by RT-PCR) and protein (by immuno-histochemistry) in the hippocampus. Results The ambulation scores, rearing scores, grooming time and sucrose consumption percentage were significantly decreased while the center,grid detention time (CDT) was significantly increased in group Ⅱ-Ⅴ as compared with control group indicating mental depression was successfully induced. The ambulation scores, rearing scores, grooming time, sucrose consumption percentage, SYP mRNA and protein expression were significantly increased while CDT was significantly decreased after treatment in group M_1 and M_2 as compared with group D indicating that propofol 90 or 110 mg/kg combined with ECT was effective for the treatment of mental depression.Conclusion Propofol 90 or 110 mg/kg combined with ECT is effective in treating mental depression while proprofol 130 mg/kg combined with ECT is not. Excessive inhibition of SYP expression in hippocampus by large dose of propofol may explain the mechanism.`
