Objective To evaluate the clinical efficacy of “Shamrock” ultrasound images?guided lumbar sympathetic ganglion blockade ( LSGB) . Methods Sixty patients of both sexes, aged 18-60 yr, weighing 50-70 kg, of American Society of Anesthesiologists physical statusⅠorⅡ, undergoing unilater?al LSGB, were divided into groupⅠ ( n=30) and group Ⅱ ( n=30) using a random number table. In group Ⅰ, unilateral LSGB was performed at the L2 level under ultrasound guidance with paramedian trans?verse scanning. In groupⅡ, unilateral LSGB was performed at the L2 level under ultrasound guidance with“Shamrock” ultrasound images. After final needle position was confirmed, 2% lidocaine 6?0 ml was ad?ministered in each patient. At 20 min before and after LSGB, the visual analogue scale scores and skin temperature of the big toe of the affected foot were recorded, and the successful blockade and visibility of important paravertebral structures on ultrasound images were recorded during puncture. Results The visu?al analogue scale scores were significantly lower, and the skin temperature on the affected side was signifi?cantly higher after LSGB than before LSGB in both groups ( P<0?05) . The important paravertebral struc?tures such as erector spinae, quadratus lumborum, psoas major, transverse process of L2 vertebrae, and the curved edge of L2 vertebrae were visible in both groups. The visibility rate of the inferior vena cava or ab?dominal aorta on ultrasound images and the success rate of blockade were significantly lower in group Ⅰthan in group Ⅱ (P<0?01). Conclusion Compared with paramedian transverse scanning, LSGB has some advantages such as real?time monitoring, higher success rate of blockade, better efficacy and avoiding damage to great vessels when performed under “Shamrock” ultrasound image guidance.

OBJECTIVETo investigate the resident dietary cadmium exposure in Jiangsu province and assess its safety.

METHODSCadmium concentration of 229 food items under 12 food groups were obtained from the food surveillance program in Jiangsu province between 2001 and 2006. Food consumption data of 778 food items of 3938 residents who were classified into four age groups (< 7, 7-, 13-, 18-) were got from the Nutrition and Health Status Survey of the Jiangsu resident in 2002 by 24 h dietary recall on three consecutive days. Dietary cadmium exposures for the residents of different age groups were obtained by using both point estimation and simple distribution estimation through integrating the two datasets above. The safety of dietary cadmium exposure was assessed.

RESULTSPoint estimation showed that the average dietary cadmium intakes of different age groups ranged from 5.7 to 8.6 microg/kg, accounting for 567.1% - 857.1% of the provisional tolerable daily intake (PTDI, 1.0 microg/kg). Result of simple distribution method showed mean daily cadmium exposure of different age groups ranged from 0.2 to 0.4 microg/kg, accounting for 20% - 40% of PTDI. Mean weekly cadmium exposure ranged from 1.4 to 2.5 microg/kg, accounting for 20% - 35.7% of the provisional tolerable weekly intake (PTWI, 7.0 microg/kg). The mean daily dietary cadmium exposure for different groups were as follows: < 7, 0.4 microg/kg; 7-, 0.3 microg/kg; 13-, 0.2 microg/kg; 18-, 0.2 microg/kg. Differences of daily dietary cadmium exposures among groups were significant (F = 69.0, P < 0.05). The mean weekly dietary cadmium exposure for different groups were: < 7, 2.5 microg/kg; 7-, 2.0 microg/kg; 13-, 1.4 microg/kg; 18-, 1.4 microg/kg. Differences of weekly dietary cadmium exposures among groups were also significant (F = 41.6, P < 0.05). The P97.5 of daily cadmium exposure for < 7 and 7- were 1.4 and 1.2 microg/kg, respectively, both of which were higher than PTDI. The P99.0 of daily cadmium exposure for 13- and 18- were 1.3 and 1.1 microg/kg, respectively. The daily dietary exposure from cereals for different age groups were 21.5 - 253.4 microg/kg, occupying 42.2% - 47.8% of the total daily exposure. Vegetables were 8.0 - 119.4 microg/kg, occupying 14.6% - 20.1%.

CONCLUSIONThe average level of dietary cadmium exposures for residents in Jiangsu province calculated by simple distribution estimation were much lower than that calculated by point estimation and were considered to be at no risk. P97.5 or P99.0 of daily or weekly dietary cadmium exposure of different age groups exceeded PTWI and PTDI. The main food types of dietary cadmium exposure were cereals and vegetables.

AIMThe anti-gastric ulcer constituents from the roots of Crepis napifera (Franch) Babc (Compositae) were studied.

METHODSSolvent partition, Si gel and Rp-18 column chromatography, crystallization and spectral methods were used to extract, isolate and identify two compounds. The activity of compound 1 was tested on the rat stomach by determining the effect on aspirin-induced gastric lesions and on histamine-stimulated gastric acid secretion.

RESULTSTwo sesquiterpene lactone glycosides, taraxinic acid-1'-O-beta-D-glucopyranoside (1) and 11,13-dihydro-taraxinic acid-1'-O-beta-D-glucopyranoside (2) were obtained. Compound 1 at the dose of 80 mg.kg-1 p.o. inhibited significantly the development of aspirin-induced gastric lesions in the rat and at an i.v. dose of 70 mg.kg-1 did not affect histamine-stimulated gastric acid secretion in the lumen-perfused rat stomach.

CONCLUSIONCompound 1 is the active component of the plant which protects gastric mucosa and exhibits anti-gastric ulcer action.

OBJECTIVETo investigate the effect of cinobufagin on nuclear factor-kappaB (NF-kappaB) pathway of liver cancer cell line HepG2.

METHODSDual-luciferase cis-reporting system was used to detect the relative value of pNF-kappaB-TA-luc upon tumor necrosis factor-alpha (TNF-alpha) stimulation of NF-kappaB pathway. Western blotting was used to detect the protein level of NF-kappaB p65, and RT-PCR was used to detect the gene transcription level of intercellular adhesion molecule-1 (ICAM-1), a target downstream gene of NF-kappaB.

RESULTSAt the concentration of 0.25 and 0.5 microg/ml, cinobufagin significantly lowered the relative value of luciferase (P<0.05). The results of Western blotting showed that cinobufagin significantly suppressed the protein expression of NF-kappaB p65. The transcription level of ICAM-1 was reduced by different doses of cinobufagin.

CONCLUSIONThe anti-cancer effect of cinobufagin may be related to its activity in inhibiting the activation of NF-kappaB pathway.

The aim of the present study was to investigate the effect of a short-term (3-day) simulated microgravity with and without daily dorsoventral gravitation (-G(x)) for 1 h on myogenic tone and vasoconstrictor responsiveness of the middle cerebral artery and mesenteric third-order small artery in rats. The tail-suspension (SUS) model was used to simulate cardiovascular deconditioning due to microgravity. Daily restoring to normal standing (STD) posture for 1 h was adopted to provide -G(x) as the countermeasure. Segments of middle cerebral artery and mesenteric third-order small artery were isolated and cannulated. Vascular diameters in response to increased intraluminal pressure (from 20 mmHg to 120 mmHg, by 20 mmHg steps) of isolated arteries under no-flow conditions were recorded by a Pressure Myograph System in both physiologic salt solution (PSS) (active diameter, Da) and calcium-free PSS (passive diameter, Dp). The myogenic tone was calculated by (Dp-Da)/Dpx100%. Vasoconstrictor responsiveness of the isolated middle cerebral artery to serotonin and that of small mesenteric artery to phenylephrine were assessed in the PSS under an intraluminal pressure of 40 mmHg. The results showed that SUS induced an enhancement of the myogenic tone and vasoconstrictor responsiveness in the isolated middle cerebral artery but a depression of those in the small mesenteric artery. Daily STD for 1 h prevented the depression of myogenic tone and vasoconstrictor responsiveness in the small mesenteric artery, but did not prevent the functional enhancement in the middle cerebral artery. These data suggest that a short-term simulated microgravity may result in different alterations in the function of the cerebral artery and the resistance vessel in the hind-body. Moreover, only the decrease of function in these resistance vessels, not in the cerebral arteries, can be prevented by such a countermeasure of daily STD for 1 h.
