Objective To investigate the evaluation value of magnetic resonance spectroscopy (MRS) combined with S-100B protein in the severity and prognosis in patients with acute subdural hematoma ( ASDH).Methods Eighty cases of ASDH patients and 20 cases of healthy check-up were selected.MRS was used to test NAA/Cr, Cho/Cr, NAA/Cho, and Glx /Cr in thalamus and corpus callosum.The blood S-100B protein was detected in 72 h after injury.The relationships of those MRS detection indices with glasgow coma scale ( GCS) and glasgow prognostic score ( GOS) for 2 months after injury were analyzed .Results MRS detection in-dex and the S100B protein in ASDH were compared between each group relative to normal control group , all difference had statistical significance ( P <0.05).As aggravating the severity of traumatic brain injury , Cho/Cr, Glx/Cr ratio, and S-100B protein concentra-tion were elevated , and NAA/Cho and NAA/Cr were reduced .All differences were statistically significant among poor recovery , good recovery, and normal control groups ( P <0.05).For patients with traumatic brain injury, there were worse prognosis, the higher ra-tios of Cho/Cr and Glx/Cr, higher concentration of S-100B protein, and lower ratios of NAA/Cho and of NAA/Cr.GCS score and GOS scores were negatively correlated with Cho/Cr and Glx/Cr ratios of corpus callosum , and were positively correlated with NAA/Cho, NAA/Cr ratios of corpus callosum .S-100B protein was positively correlated with Cho/Cr and Glx/Cr, and was negatively correlated with NAA/Cho and NAA/Cr.MRS combined S-100B can improve the prognosis of patients with up to the accuracy of 81%.Conclu-sions MRS detection in the early stage after injury of ASDH patients has important value in assessment of the severity of the injury and its prognosis , the accuracy of assessment of prognosis is improved with a combination of MRS detection and blood S -100 B protein meas-urement.

Objective To quantitatively analyze and compare the texture features of thermal and chemical lesions on the porcine striated muscle, in vitro extracted from high-frequency ultrasonograms using computer-assisted image analysis technique, and to investigate the application values. Methods The thermal lesion and chemical lesion were induced in vitro in porcine striated muscle by microwave ablation and anhydrous acetic acid injection, respectively. The two dimension (2D) ultrasonographic ifndings were qualitatively compared between the groups of thermal and chemical lesion models, in which eight textural features in geometric mathematics extracted from 2D ultrasonograms were quantitatively analyzed by a technique of computer-assisted image analysis named multiscale decomposition method of echo intensity of interface relfections. Results As expected, microwave ablation and anhydrous acetic acid caused signiifcant changes of several texture features extracted from ultrasonograms. There were significant differences between the normal group and microwave ablation group in grayscale mean (Mean), irregularity (IRGL) and periodicity of distribution (POD) as follows (Mean: 1.9143±0.2914 vs 1.2334±0.3357, t=-5.306, P=0.000; IRGL: 0.5577±0.0334 vs 0.5092±0.0459, t=-2.957, P=0.007; POD: 0.000 27±0.000 005 vs 0.000 29±0.000 008, t=4.782, P=0.000). There were signiifcant differences between the normal group and anhydrous acetic acid injection group in number of blobs (NOB), size of blobs (SOB) and periodicity of distribution (POD) as follows (NOB: 51.0324±13.6998 vs 31.6042±4.8315, t=4.633, P=0.000; SOB:16.4843±3.9349 vs 25.6230±2.3555, t=6.903, P=0.000;POD:0.000 26±0.000 015 vs 0.000 29±0.000 008, t=-4.459, P=0.000). For each group of injured regions, there were significant differences between the microwave ablation group and anhydrous acetic acid injection group in Mean, IRGL, NOB and SOB as follows (Mean: 1.2664±0.2688 vs 1.9143±0.2914, t=-5.661, P=0.000; IRGL: 0.5220±0.0422 vs 0.5577±0.0334, t=-2.295, P=0.032;NOB:51.0324±13.6998 vs 34.5856±2.6362, t=4.048, P=0.000;SOB:16.4843±3.9349 vs 25.3176±2.3501, t=-6.676, P=0.000). Conclusion Technique of computer-assisted image analysis named multiscale decomposition method of echo intensity of interface relfections, based on multiscale blob features extraction, was useful to differentiate ultrasonic texture features between the groups injured in our study, which established quantitative muscle ultrasound as a practical and reliable tool for the muscle injury diagnosis to distinguish the structural changes induced by different physiochemical factors.

OBJECTIVETo evaluate the role of adiponectin in regulating tumor necrosis factor alpha (TNF alpha) production and preventing fulminant autoimmunological damage of hepatocytes following concanavalin A (Con A) injection into mice.

METHODSThree days after recombinant plasmids pAA-neo-mAd were injected into the mice via the tail veins, Con A was injected into the mice. Mice transfected with empty pAA-neo vector served as controls. The serum levels of alanine aminotransferase (ALT), TNF alpha and adiponectin were detected, and histological examination of livers was carried out at different time points after the Con A injection. All results were subjected to statistical analyses.

RESULTSHistological examinations showed that the damage in livers of mice with high serum adiponectin levels was milder than that of the controls. The serum levels of ALT and TNF alpha were both lower than those of the controls (P less than 0.01, respectively). Statistical analyses showed the serum levels of ALT was negatively related to the levels of adiponectin in the sera (r=-0.5034).

CONCLUSIONAdiponectin is effective in protecting hepatocytes from Con A-induced immunological injury. The mechanism of this protective effect may be caused by inhibiting the synthesis and/or release of TNF alpha.

OBJECTIVE: To establish a rat model of cervical syndrome (CS) with kidney deficiency. METHODS: A group of 30 three-month-old female Sprague-Dawley rats were randomly divided into normal control group, CS group and CS with kidney deficiency group (combined group), with 10 rats in each group. Rats in the normal control group received no treatment, rats in the CS group underwent only resection of cervical muscles and ligaments as unbalanced dynamic and static animal model, and rats in combined group underwent resection of both cervical muscles and ovaries as kidney deficiency model. Serum and cervical intervertebral discs were collected. Kidney deficiency was determined by observing the morphologic changes of uterus and appendages, detecting the weight of uterus and appendages and the content of serum estradiol (E(2)). The degeneration of intervertebral discs was determined by detecting the histopathology, the expressions of type II collagen and type X collagen proteins, and the expressions of aggrecan-1 (Agc1), type II procollagen gene (Col2a1), matrix metalloproteinase-13 (MMP-13) and tissue inhibitor of metalloproteinases-1 (TIMP-1) mRNAs. RESULTS: Compared with those in the normal control group and CS group, the rats in the combined group were noted with the uterus atrophied, the caliber of oviduct thinned, the weight of uterus and appendages diminished obviously, the content of serum E(2) decreased, cervical intervertebral disc degenerated more seriously, type II collagen protein expression decreased, type X collagen protein expression increased, Agc1 and Col2a1 mRNA expressions in intervertebral disc decreased, and the MMP-13 mRNA expression increased. CONCLUSION: The rat model of CS with kidney deficiency is established. Kidney deficiency can aggravate cervical intervertebral disc degeneration.
