BACKGROUND: Stellate ganglion block has many functions by improving brain circulation, modulating immunity, reducing plasmic catecholamine content, interleukin-6 is one of the most sensitive and important predictors and mediators for acute organic stress response, playing neuroprotective and neurotoxic double roles in brain ischemic injury.OBJECTIVE: To observe the effect of stellate ganglion block in rat brain during ischemic-reperfusion period on the changes of serum interleukin-6,in order to probe the role of stellate ganglion block in brain ischemicreperfusional injury.DESIGN: Randomized controlled experimentation.SETTING: Anaesthesia Department of Taihe Hospital Mfiliated to Yunyang Medical College, and Anaesthesia Department of Renmin Hospital Affiliated to Yunyang Medical College.MATERIALS: This experiment on animals was carried out at the Experimental Center of Taihe Hospital Affiliated to Yunyang Medical College at March 2003, interleukin-6 reagent kit and determination was provided and conducted by the immunity research institute of Chinese People's Liberation Army General Hospital. Totally 28 big-ear healthy rabbits in which male or female was not limited were selected and randomly divided into stellate ganglion group, saline comparison group, blank comparison group and sham operation group with 7 rabbits in each group.METHODS: A pipe was set approximate to the stellate ganglion of all animals by operative method, six-vessels block method was used to simulate whole brain ischemic-reperfusion model, in stellate ganglion block group,artery clamp was lossen for reperfusiion at 15 minutes after ischemia, simultaneously 2.5 g/L bupivacaine was continuously pumped into left side of stellate ganglion for nerve block, which replaced by physical saline and nothing in respectively physical saline comparison group and blank comparison group, while rabbits in sham operation group were only subjected to surgery without artery clamp. RIA was used to determine serum interleukin-6 content at before ischemia, reperfusion of 10 minutes, 4 hours, 10hours, when 20 hours and 30 hours individually.MAIN OUTCOME MEASURES: Serum interleukin-6 content in each group at various post-reperfusional time points.RESULTS: Totally 28 big-ears white rabbits were enrolled in this experiment and all data was entered the result analysis. Interleukin-6 content was on an increasing tendency in all groups, while was higher in stellate ganglion block group than in sham operation group only at reperfusion 30time point, the difference has significance [(321±52) and (299±45) ng/L,P ＜ 0.05]; Comparing to pre-ischemic group, interleukin-6 in physical saline group began increase remarkably from onset of reperfusion 4 hours[(365±46) ng/L], but began obviously increase at reperfusion 10 hours in blank comparison group [(368±31) ng/L, P ＜ 0.05]. The difference of interleukin-6 among stellate ganglion block group, sham operation group,physical saline group and blank comparison group does not have statistical significance (P＞0.05); the level of interleukin-6 in physical saline group and blank comparison group were higher than in sham at all reperfusion 4-30 hours, and even higher than in stellate ganglion group after reperfusion 10 hours, the difference has significant meaning (P ＜ 0.05). Moreover the increase of interleukin-6 content in stellate ganglion block group was remarkably lower than physical saline comparison group and blank comparison group (P ＜ 0.05).CONCLUSION: Stellate ganglion block may obviously reduce serum interleukin-6 level in rabbit brain during ischemic-reperfusion period, implying stellate ganglion block has a certain protective and curative function on the whole brain ischemic-reperfusion damage, and considered as a promising way in the treatment of brain ischemic-reperfusion damage.

The dynamic of endophytic bacteria at different growth stage of tomato and use of these endophytic bacteria to control tomato bacterial wilt were studied. The results showed that endophytic bacteria could be found in the tomato seeds and their quantities reached the highest peak in the adult plants both in resistant and susceptible cultivars. The amount of endophytic bacteria in adult plants of resistant tomato cultivars was 2.43?10~5CFU/g FW in the root and 22.9?10~4 CFU/g FW in the stem, while the amount of endophytic bacteria in adult plants of susceptible tomato cultivars was 9.8?10~4CFU/g FW in the root and 13.4?10~4CFU/g FW in the stem respectively. Seventeen strains of endophytic bacteria from resistant cultivars and only seven strains from susceptible cultivars were found to be antagonistic to Ralstonia solanacearum. In addition, some strains of endophytic bacteria had the abilities of promoting tomato seed germination and controlling tomato bacterial wilt, among which, strain 5R and 3R had better control effect of 91.7% and 81.3% respectively.

The population of bacterial physiological groups in tomato with different resistant to Ralstonia solanacearum was studied. The results suggested that endophytic bacterial communities and population in tomato variety changed with different resistant cultivars, different stages of tomato and seasons. It was con-ducted that the amount of ammoniation bacteria was the highest among the seven physiological bacterial groups. There were more ammoniation bacteria in high resistant tomato cultivars than that in high suscepti-ble cultivars. It may indicate that ammoniation bacteria played a key role in the occurrence of tomato bacte-rial wilt. In addition, the total amount of physiological bacteria in resistant cultivars was more than that in susceptible cultivars in different stages of tomato, and the tendency of changing displayed fluctuation. The average level of quantities of the ammoniation bacteria, nitrifiers bacteria, erobic nitogenfixing bacteria and desulphate reducer bacteria in summer were higher than that in winter, while the population of the sulphate reduced bacteria in winter was higher than that in summer. Furthermore, the amount of anaerobic bacteria was the least among them.

To decrease the oxygen content in the cell is a key method to improve hydrogen production in Chlamydomonas reinhardtii.A new approach was developed by transforming the leghemoglobin gene lba,which has high affinity to oxygen,into the chloroplast of C.reinhardtii to get a low dissolved oxygen in the cell and result into improvement of H2 ase activity and H2 yield. The results showed that lba was successfully transformed into the chloroplast of C.reinahrdtii strain 849 and did not affect its growth significantly. The work paved the road for further regulation of lba expression in the chloroplast to improve of hydrogen production of C.reinahrdtii.

OBJECTIVETo study clinical value of shear wave elastography (SWE) in the evaluation of neck-shoulder myofascial pain syndrome.

METHODSFrom December 2013 to July 2014,30 patients diagnosed as neck-shoulder myofascial pain syndrome were in the treatment group,including 17 males and 13 females, with an average age of (44 ± 3) years old. Thirty healthy people were in the control group, including 22 males and 8 females, with a mean age of (37 ± 5) years old. The patients in the treatment group were treated with manipulation, once every other day, total 7 times. The SWE was used to detect tension part of trapezius muscle of patients in the treatment group before and after treatment, as well as to detect muscle belly at the descending part of trapezius muscle in the control group. The tissue elasticity and Yang's modulus value were recorded and compared.

RESULTSThe tissue elasticity chart of patients in the treatment group before treatment was mainly greenish blue with the score of 3.70 ± 1.53, and the Yang's modulus was (43.4 ± 15.6) kPa. The tissue elasticity figure after treatment was mainly blue with the score of 2.40 ± 0.87, and the Yang's modulus was (29.0 ± 5.9) kPa. Whereas in the control group, the tissue elasticity figure was mainly blue with the score of 1.60 ± 0.72, and the Yang's modulus was (24.0 ± 7.6) kPa. These were statistical differences between the two groups (P = 0.000).

CONCLUSIONSWE can be used as an evaluation method of manipulation treatment for neck-shoulder myofascial pain syndrome, which is an objective and sensitive detection method.
