Seventy two patients with tension type headache (TTH) were divided randomly into two groups: massage group was treated with massage on the trigger points of neck muscles, and control group was treated with drugs.The frequency, duration, severity of TTH, use of painkiller and electromyography of pericranial muscle (temporalis muscle and masseter muscle ) were recorded before and after treatment.The frequency, duration and severity of TTH, the frequency of painkiller use, and amplitude and frequency on electromyography of pericranial muscles in massage groups after treatment were reduced significantly (P ＜0.05 ) .In summary, massage on the trigger points in neck muscles has significant therapeutic effects for TTH.

Objective To determine the changes in action potential peak value and maximal nerve conduction velocity of rabbit sciatic nerve after being exposed to different doses of high intensity ultrasound (HIU) and establish the experimental basis for the use of HIU in patients with refractory pain. Methods Eighty New Zealand white rabbits of either sex weighing 2.0-2.5 kg, aged 5-10 months were randomly divided into four groups with 20 rabbits in each group :group Ⅰ 0 second;group Ⅱ 15 seconds;group Ⅲ 25 seconds and group Ⅳ 50 seconds. The animals were anesthetized and placed in the prone position. Sciatic nerves were exposed to 4 different doses of HIU (7.1 MHz, 40 W/cm2 f55 0 s, 15 s, 25 s, 50 s) in the four groups. The animals were allowed to recover. At 5 intervals (1 and 2 weeks, 1, 3 and 6 months) after exposure to HIU, 4 animals in each group were anesthetized and recording electrodes were placed on sciatic nerves at 2 cm distal to the site of HIU radiation, tibial and sural cutaneous nerves. The amplitude (peak value) and latency of action potential and maximal conduction velocity of the nerves were recorded. Sciatic nerves were obtained from one of the four animals for light and electron microscopic examination. Results The larger was the dose of HIU, the more time was needed for the injuried nerve to recover. In group Ⅰ (0 s) there were no significant changes in action potential peak value and maximal nerve conduction velocity at any interval after exposure to HIU;in group Ⅱ (15 s) there were slight changes in the electrophysiological parameters and the changes recorded on tibial nerve returned to normal soon while those recorded on sural cutaneous nerve returned to normal one month later; in group Ⅲ (25 s) there were significant changes in the electrophysiological parameters and it took 3 months for tibial nerve but 6 months for sural cutaneous nerve to recover;in group Ⅳ (50s) the nerves were completely blocked, no action potential was recorded and no recovery was observed after 6 months. Light and electron microscopic examination showed that in group 1 no significant changes of nerves were observed; in group Ⅱ there was slight deformation of myelin sheath which returned to normal 2 weeks later; in group Ⅲ sheath was broken or lost, and axon degeneration was observed at 1 week after exposure to HIU and the changes disappeared 1 month later; in group Ⅳ necrosis of the nerve was observed and no recovery was observed 6 months later. Conclusion HIU can be used for the treatment of refractory pain. Analgesia can be achieved with loss of only part of motor function. The nerve can be permanently blocked by HIU if necessary.

Objective To investigate the feasibility of labeling mice spleen lymphocytes with superparamagnetic iron oxide(SPIO)and in vitro MR imaging of the labeled cells.Methods Spleen lymphocytes of 5 mice were isolated and then labeled with SPIO of 100,50,25,15,10,5 μg/ml,which was previously prepared with PLL.Prussian blue staining was performed to show the intracellular iron.Cell viability was compared among fresh,labeled and unlabeled cells.Different concentrations of mice spleen lymphocytes were screened using 3.0 T MR on T2WI,T2 * WI and SWI sequences in vitro.Cell viability was compared using independent-sample t test between groups.The MRI values among different groups were compared using one-way ANOVA.Results SPIO prepared with PLL could successfully label mice spleen lymphocytes,the optimum concentration of SPIO was 5 μg/ml.The Prussian blue staining showed intracellular blue spots and a labeling efficiency of(93.6 ± 2.1)％.Three groups of fresh,labeled and unlabeled cells showed a Trypan blue staining result of(94.8 ± 3.1)％,(88.7 ± 2.7)％,and(88.9 ±3.2)％,respectively; no statistically significant difference was found in cell viability between labeled and unlabeled lymphocytes(t =0.281,P ＞ 0.05); however,the cell viability of fresh cells were statistically significant higher than the labeled and unlabeled lymphocytes(t =8.125 and 7.253 respectively,P ＜0.05for all).Among the T2 WI,T2 * WI and SWI sequences under the same concentrations of cells,the SWI sequence was the most sensitive.Conclusions The mice spleen lymphocytes can be effectively labeled with SPIO with no impact on cell viability,and MR can be used to track these labeled cells in vitro.The SWI sequence is the most sensitive.

Objective To observe the pathologic changes of the rabbit sciatic nerves after the exposure of high intensity ultrasound(HIU) (7.1 MHz,45.86 W/cm2)and to establish the experimental base for protection of the nerves near the organs and tissues treated with HIU. Methods The rabbit sciatic nerves were exposed to HIU of different doses as defined by the action time of the ultrsound(0, 15, 25 and 50 seconds, respectively); The Pathological changes of the nerves were observed at different times after exposed to HIU(1 week,2 weeks,1 month,3 months and 6 months). Results In 0 s (45.86 W/cm2?0 s)group, no significant pathological changes were observed. In 15 s(45.86 W/cm2?15 s) group, slight deformation of the myelin sheath were observed and recovery took place at 2 weeks. In 25 s (45.86 W /cm2?25 s) group, the nerves became broken partly and recovered at 3 months. In 50 s(45.86 W/cm2?50 s) group, great part of the nerves got coagulation necrosis and had not recovered at 6 months. Conclusion The larger the dosage of HIU, the higher degree the injury of the sciatic nerve, the more difficult the nerves to get repaired.

Objective To investigate the serum levels change of vascular endothelial growth factor (VEGF) during operation of non-small-cell lung cancer (NSCLC). Methods 120 cases of NSCLC patient diagnosed by pathology as well as with operation indication were selected as the experimental group. The patients selected were required without any chemotherapy or radiotherapy before operation, besides that, they should have good compliance and free will to be examined. During the process of experiment, 60 cases concluded as healthy in the physical examination were chosen as control group. The correlative information of the experimental group were collected including periphery blood specimen collected in 3 days before the operation, and of the 1st day, 7th day and 30th day after the operation while the periphery blood specimen of control group were collected. The serum levels of VEGF were detected by adopting enzyme linked immunosorbent assay (ELISA) method. Results The serum levels of VEGF in NSCLC patients before operation, of the first postoperative day, of the seventh postoperative day and of the thirtieth postoperative day were significantly higher than that in healthy people (P＜0.01), respectively (279.14±44.89)μg/L, (282.70±42.74) μg/L, (353.79±44.55) μg/L, (178.40±43.43) μg/L and (91.40±16.55) μg/L. The serum levels of VEGF in NSCLC patients showed positive correlation with the stages (P＜0.01). Conclusion The serum levels of VEGF in NSCLC patients scale up. At the same time it shows positive correlation with the stages of the primary tumor. The serum levels of VEGF in NSCLC patients scales up by degrees in one week after the operation, and drop one month later.

Both dosage and volume of local anesthetics taken for extradural anesthesia in ESWL were studied in 112 cases. The results showed that small dose of coxylacaine (1.33% of xylocaine and 0.16% Bupivacaine in 3-5ml) given extradurally is not only safe but also suitable for ESWL without obvious side effect
