The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO₂ of S group were significantly higher before CPB time of rewarming than that before SGB (P < 0.05), much higher than corresponding non-blocked side rSO₂ before CPB (P < 0.05), and much higher than rSO₂ level in group C before CPB and after CPB (P < 0.05). The non-blocked side rSO₂ in group S before anesthesia were much lower than basic levels and those in group C (P < 0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO₂ compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.

Objective Toinvestigate the effects of carbon dioxide pneumoperitoneum on cardiovascular system by making use of arterial pressure waveform analysis( FloTrac/Vigileo system) to observe the change of heart function of patients undergoing laparoscopy cholecystotomy. Methods Forty patients scheduled for elective laparoscopy cholecystotomy were divided into two groups with 20 cases each by random sampling.Ventilatory capacity was fixed (tidal volume was 10 ml/kg, frequency was 12 times/min) in group A and adjusted to keep arterial carbon dioxide tension (PaCO2) and end expiration carbon dioxide tension(PETCO2)in normal range in group B. The parameters, such as mean arterial pressure (MAP), cardiac output(CO),stroke volume (SV), stroke volume variability (SVV), heart rate(HR), pulse oxygen saturation (SpO2),PETCO2, PaCO2 were recorded and analyzed. Results In group A:HR,MAP,CI,SVV,PaCO2 and PETCO2 were increased at 10,30 min after pneumoperitoneum (P <0.05 or <0.01),there was no significant difference in SVV between the end of pneumoperitoneum and 5 min after intubation [(8 ±2)% vs. (9 ±3 )%](P> 0.05 ) ,but HR, MAP, CI,SVI,PaCO2 and PETCO2 increased significantly (P< 0.05 or < 0.01 ). In group B: HR, MAP, CI, SVI, PaCO2 and PETCO2 at 10,30 min after pneumoperitoneum were no changes (P >0.05 ), SVV was higher than that at 5 min after intubation (P < 0.01 ), there was no significant difference in SVV between the end of pneumoperitoneum and 5 ain after intubation [(9 ± 2)% vs. ( 10 ± 2)%] (P >0.05 ). HR, CI, SVI, PaCO2, PETCO2 at 30 min after pneumoperitoneum and the end of pneumoperitoneun were significantly higher in group A than those in group B (P < 0.05 or < 0.01 ). Conclusions During carbon dioxide pneumoperitoneum, hypercapnia can increase MAP, HR, CO,SV significantly, and intra abdominal pressure can decrease preload by hindering the reflow of inferior vena cava and abdominal viscera veins. Arterial pressure waveform analysis can promptly reflect the effects of carbon dioxide pneumoperitoneum on cardiovascular system and be in favour of adjusting the respiration parameters and managing transfusion in laparoscopic surgery.

Objective To investigate the effect of elemene on mRNA expressions of tumor necrosis factor (TNF) receptor associated factor 6 (TRAF6) and caspase-8 in tumor tissues of mice bearing hepatoma H22.Methods Forty BALB/c mice models bearing hepatoma H22 were established by subcutaneous inoculating tumor cells.Forty BALB/c mice were randomly divided into 4 groups:model group,low-and high-elemene dosage groups,and cisplatin group.The tumors after executing mice were weighted.The mRNA expressions of TRAF6 and caspase-8 in tumor tissues were detected by quantitative real-time reversetranscription polymerase chain reaction (RT-PCR).Results The dosage of elemene could inhibit tumor growth.The inhibition ratio of cancer in the low-and high-elemene dosage and cisplatin group was 24.2%,27.4%,and 28.2%,respectively.It reduced significantly tumor weights(P <0.01).Compared to the model group,the expression level of TRAF6 mRNA on tumors was decreased significantly,while the expression level of caspase-8 mRNA was increased significantly in the other groups(P < 0.05).Conclusions The present results indicated that molecular mechanism of inhibition of liver cancer growth treated by elemene might be through down-regulating mRNA expressions of TRAF6 and caspase-8,promoting tumor cells apoptosis,and achieving the anti-tumor effect.

1.0~(?)1.5 cm(14.81%)(P=0.10).There was no lymph node metastasis in tumors less than 1.0 cm in diameter. The 5-year survival rates for cases with or without lymph node involvement were 92.31% and 60.0%,respectively,the difference was significant(P=0.000).The 5-year survival rates of 12 patients showing ground-glass opacity(GGO)on chest CT was 91.67% without any lymph node involvement.Conclusions:There is mediastinal and hilar lymph node involvement even with tumor diameter less than 2 cm.The results of the present study suggested that routine lymph node dissection is necessary even for cases with tumor diameter less than 2 cm.However,if the tumor is within 1.0 cm in diameter with obvious GGO showing on chest CT,these are good candidates for partial resection without mediastinal lymph node dissection.

OBJECTIVETo observe anti-cancer effects of Jianpi Jiedu Recipe (JJR) on liver cancer (LC) rats with Pi deficiency syndrome (PDS) and its relation with the third complementary-determining region gene spectratyping of TCRVβ-chain (TCRVβCDR3).
METHODSRats were divided into 8 groups according to random digit table, i.e., the blank control group (normal), the PDS group, the LC model group, the LC-PDS group, high, middle, and low dose JJR groups (75.00, 37.50, 18.75 g/kg, respectively by gastrogavage, once per day), the thymus pentapeptide group (5 mg/kg, intramuscular injection, twice per week), 8 in each group. Rats in the normal group were administered with physiological saline by gastrogavage once per day. PDS rat model was prepared by bitter-cold purgation. LC model was prepared by orthotopic transplantation method. Twenty gene subfamilies of TCRβCDR3 in the thymus, liver, and LC tissues were detected by Gene Scan.
RESULTSHigh and middle dose JJR could postpone the growth of LC volume (P < 0.05), with equivalent liver index and thymus index to those of the normal group (P > 0.05). In thymus and liver tissue of the normal group, the number of clones (20 and 19), gene fragment number (220 and 113), Quasi-Gaussian distribution ratio of TCRVβCDR3 gene repertoire (100.0% and 42.1%), and fragment fluorescence peak area (6,539 ± 2,325 and 1,238 ± 439) were at the highest level among the 8 groups. TCRVβCDR3 expressions in thymus and liver tissue of high and middle dose JJR groups were approximate to those of the normal group. They were in the middle of the thymus pentapeptide group, the PDS group, the LC model group, and poorest in the LC-PDS group. TCRVβCDR3 in liver tissue expressed the best in the thymus pentapeptide group.
CONCLUSIONJJR might inhibit the growth of LC cells, and its mechanism might be related to enhancing TCRVβCDR3 spectratype expression.

Objective To observe the effects of electro-acupuncture on the E-selectin and resistin protein expression in the hippocampus of rats of chronic stress depression;To explore the role and mechanism of electro-acupuncture in the micro-environment of brain with depression. Methods 40 Fourty rats were randomly divided into four groups:blank group, model group, model+EA group, and model+fluoxetine group by using chronic stress combined with solitary raising methods, 10 rats in each group. Electro-acupuncture intervention was used 1 hour before the modeling. Electro-acupuncture was given at points Baihui (Du 20) and Yintang (Extra) for twenty minutes (2 Hz, 0.6 mA) every day. Fluoxetine was given at the volume of 5 mL/kg, dosage of 10 mg/kg. E-selectin and resistin protein expression in hippocampus were determined by biotin label-based antibody array. Results Compared with the blank group, the protein expression of E-selectin and resistin in the model group increased (fold change=1.23, 1.22). Compared with the model group, E-selectin and resistin expression decreased (fold change=0.65, 0.62;fold change=0.76, 0.65). Conclusion Electro-acupuncture intervention could down-regulate E-selectin and resistin expression in the hippocampus of chronic stress depression model.
