A FAST (fluorescence of advanced Maillard products and Soluble Tryptophan) method for identification of reconstituted milk made from skim milk powder in the fresh milk was developed. Considering milk and skim milk powders variations from different seasons and countries, milk was collected from different dairy farms in different seasons and skim milk powders were collected from different countries to measure the Tryptophan (Trp), advanced Maillard products (AMP) fluorescence values. The results showed that there were differences (P<0.01) between raw and reconstituted milk. The plot of values in each mixed level of raw and reconstituted milk had a correlation coefficient >0.97. The FAST method is a simple, rapid, low-cost and sensitive method enabling the detection of 5% reconstituted milk in fresh milk. The measurement of the Trp, AMP fluorescence values and calculation of the FAST index is a suitable method for large-scale monitoring of fresh milk samples.

OBJECTIVETo evaluate the clinical outcome of posterior total vertebral resection in treating thoracic vertebrae tumor in order to provide a safe and effective method in rebuilding spine stability.

METHODSFrom 2002.1 to 2007.12, 18 patients with thoracic spine tumor underwent posterior total vertebral resection and internal fixation. Among the patients, 10 patients were male and 8 patients were female, ranging in age from 45 to 78 years, with an average of 56 years. The course of the diseases ranged from 2 to 13 months. After the operation, the tumor reccurence was monitored by X-ray, and the tumor markers were detected.

RESULTSAll the patients were followed up for a period ranging from 12 to 60 months, averaged 29 months. All the patients showed a postoperative neurologic improvement, as well as showed radiographic evidence of solid fusion in the follow-up examinations during 3 to 9 months, with an average of (8 +/- 1.4) months.

CONCLUSIONPosterior total vertebral resection for the treatment of thoracic spine tumor is safe and effective.

OBJECTIVETo observe the effect of activation of aldehyde dehydrogenase 2 (ALDH2) by ethanol on the expression of c-Jun N-terminal kinase (JNK) in the kidney of diabetic rats.

METHODSEightheen healthy male SD rats were randomly divided into 3 groups (n = 6): normal control group, diabetes group and ethanol + diabetes group. After 8 weeks, 24 h urine samples from rats were collected to detect urinary protein content. The kidney was isolated and the ratio of kidney weight/body weight (index of kidney weight) was detected. The levels of fasting blood glucose, glycosylated hemoglobin serum urea nitrogen and serum creatinine were measured. Morphological changes of renal tissue were observed by optical microscope. The protein expressions of ALDH2 and JNK in renal tissue were detected by Western blot.

RESULTSCompared with the normal control rats, the levels of fasting blood glucose, glycosylated hemoglobin, serum urea nitrogen, serum creatinine and the index of kidney weight were increased markedly in diabetic rats. The expression of ALDH2 protein was decreased, while p-JNK, JNK protein expressions and the ratio of p-JNK/JNK were increased. The morphological observation was shown that the amount of glomerular mesangial matrix were increased, basement membrane were thickened and capillary lumen were narrowed. However,in ethanol + diabetes group, renal function was improved and the damage of renal structure was attenuated. The expression of ALDH2 protein was increased, while p-JNK, JNK and the ratio of p-JNK/JNK were decreased.

CONCLUSIONEnhanced ALDH2 expression can protect kidney in diabetic rats, which may be relevant with inhibitting the activity of JNK pathway.

Objective To explore the effects of rehabilitation for adult cervical spinal cord injury without radiological abnormality. Methods 80 patients were studied retrospectively. Results The increase of motor score of anterior, posterior and conservative group were around 5, 2 and 2, whereas that of FIM were 11, 17 and 15, respectively. The changes of sensory score were uncertain.Conclusion The effect of surgical or conservative treatment is limited on neurological recovery, while rehabilitation can bring more functional independence to patients with cervical spinal cord injury without radiological abnormality.

To further study the characteristics of changes on the molecular level of rice mutants induced in space environment, we analyzed proteins in leaves and seeds of four rice mutants (two high-tillering and two low-tillering) in the 8(th) and 9(th) generations after a 15-day spaceflight, and compared with their ground controls by two-dimentional polyacrylamide gel electrophoresis and reverse phase liquid chromatography (RPLC). In addition, the albumin, globulin, prolamine, glutelin, and amylose of the mutant seeds were analyzed by RPLC and ultra-violet spectrometry. The results showed that the low-abundance proteins of leaves in the peak tillering stage are more likely to be induced compared with their corresponding controls. The albumin, globulin, and prolamine of the mutant seeds revealed changes when compared with their controls, and the characteristics of changes in different mutants were stably inherited in the 8(th) and 9(th) generations, suggesting that they can be used as bio markers to identity the mutants induced by spaceflight. Moreover, two proteins (SSP9111 and SSP6302) were found to be expressed with high intensity (two-fold change) in different mutants, which were both correlated with photosystem according to mass spectrometry and database searching.

OBJECTIVETo investigate whether activation of mitochondrial aldehyde dehydrogenase 2 (ALDH2) and inhibition of mitochondrial permeability transition pore (mitoPTP) were involved in the cardioprotection of ethanol postconditioning in isolated rat heart.

METHODSHearts isolated from male Sprague-Dawley rats were perfused on a langendorff apparatus and subjected to 30 min of regional ischemia (occlusion of left anterior descending artery) followed by 120 min of reperfusion. The ventricular hemodynamic parameters and lactate dehydrogenase (LDH) release during reperfusion were measured. Infarct size was measured by TTC staining method and the expression of ALDH2 at mRNA level of left anterior myocardium was detected by RT-PCR.

RESULTIn contrast to ischemia and reperfusion, ethanol postconditioning improved the recovery of left ventricular developed pressure, maximal rise/fall rate of left ventricular pressure during reperfusion, reduced LDH release and infarct size. The expression of ALDH2 mRNA level was increased. Administration of mitoPTP activator atractyloside attenuated the effect of ethanol postconditioning, LDH release and infarct size were increased, and the recovery of hemodynamic parameters was inhibited. The expression of ALDH2 mRNA was decreased.

CONCLUSIONEthanol postconditioning has cardioprotection effect, which may be associated with upregulating mitochondrial ALDH2 mRNA expression and inhibiting the opening of mitochondrial permeability transition pore.

OBJECTIVETo study the result of less invasive fixation in treating comminuted fracture of distal tibia.

METHODSFrom 2002 to 2008, 48 patients with comminuted fracture of distal tibia were treated with surgery. The closed reduction and less invasive fixation were done to stable broken fibula, and the reduction by Kirschner wire to pick was used for relatively larger debris of tibia. The Kirschner wire or screw were used to fix fracture after the restore of the ankle cavity position and the alignment of the tibia. Partial weight loading and functional exercise of ankle joint were done at 6th week after operation.

RESULTSForty-eight patients were followed up for 1-24 months with an average of 12 months. All the fractures were united. According to Johner-Wruhs standard to value the result by factors of pain, deformity, motion range of joint,with or without injury of nerve and blood vessel. Thirty-eight cases obtained excellent result, 8 good, fair 2. The rate of excellent and good were 95.8%.

CONCLUSIONLess invasive fixation has ascendancy such as easy operation, less injury of soft tissue, reliable fixation, which can maximally protect periosteum. It is a choice for treating comminuted fracture of distal tibia.
