OBJECTIVETo explore the effects of sacral canal injection on nerve root local inflammatory factors in rat model with lumbar disc herniation, in order to identify its mechanism of treatment.

METHODSForty-eight male SD rats were randomly divided into sham operation group(group A), model group (group B), Chinese medicine group(group C) and western medicine group(group D). There were 12 rats in each group. The model of lumbar disc herniation was established using compression and inflammatory stimulation in group B, C, D. All rats were given epidural catheterization and group A and B with physiological saline (1 ml/kg), group C with mixed liquor of 2% lidocaine and compound Danshen injections and physiological saline (2:2: 16) and group D with mixed liquor of 2% lidocaine and triamcinolone acetonide injection and physiological saline (2:2:16), once a week for a total of three treatments. Four rats were killed every 1 week after injection for once, and the inflammatory factors of tumor necrosis factor (TNF-alpha), prostaglandin E2 (PGE2), interleukin-l (IL-1) and interleukin-6 (IL-6) were detected by ELISA method.

RESULTSThe levels of TNF-alpha, PGE2, IL-1 and IL-6 in compressed nerve tissues in group B were increased than those of group A (P < 0.01). The levels of PGE2, IL-1 and IL-6 in group C and D were decreased than those of group B, and group D was much less(P<0.05). There was no significant difference in level of TNF-alpha among group B, C, D (P > 0.05).

CONCLUSIONCompound compression with inflammatory stimulation can lead to massive release of inflammatory mediators, such as TNF-alpha, PGE2, IL-1 and IL-6. Both injection with compound Danshen injections and triamcinolone acetonide injections by sacral canal can reduce the levels of part inflammatory mediators (PGE2, IL-1 and IL-6), and the effect of Glucocorticoid is better than Danshen (P < 0.05).

BACKGROUND:Due to the differences of sport events and individual metabolic characteristics of athletes, it is difficult to establish uniform biological indexes for training monitoring. Current individual evaluation is a longitudinal analysis relying on experience or numerical variation width, which is less objective.OBJECTIVE: To explore the individual function assessment and monitoring by monitoring blood biochemical indexes and brain function indexes in elite gymnasts, in order to accurately reflect the body changes resulting from training loads. METHODS:Thirty gymnasts from the Chinese national gymnastics team preparing for London Olympic Games were enroled in this study and monitored from the last winter training until the London Olympic Games. The blood biochemical indicators and brain function indicators were measured and assessed individually according to according to the principle of quality control (alert value=mean±SD, and controled variable=mean±2SD). RESULTS AND CONCLUSION:Under the relatively uniform test conditions, it is feasible to individualy assess the blood biochemical and brain function indexes of elite gymnasts in accordance with the principle of quality control, which is more accurate and objective to reflect the body changes under training load and the current state of athletes. In addition, the combined monitoring of blood biochemical indexes and brain function indexes is more comprehensive to evaluate the body function and status of elite gymnasts.

Objective To clone the genes coding for cysteine proteases (CPs, TvCPs) from Trichomonas vaginalis and to analyze their genetic variations with the related sequences from NCBI database (GenBank) and T. vaginalis Genome Project database from The Institute for Genomic Research (TIGR). Method TvCP genes were amplified using PCR, and inserted into vector pET28b or pBS-T. The recombinant plasmids were then transformed to Escherichia coli BL21 or Top10 strain. The recombinant plasmids were used for sequencing. Homologous TvCP genes were blasted based on NCBI GenBank and TIGR T. vaginalis Genome Project database. The sequences of cloned TvCP genes were aligned and clustered by Clustal X (1.83 version) with retrieved sequences. Comparisons of amino acids among cathepsin L-like TvCPs, human L-like cathepsins and papaya papain were performed using DNAstar software, and their phylogenic tree was constructed based on neighbor-joining method using Clustal X. Results Two TvCP3 clones and one TvCP2 had a high identity of more than 99% with their responding TvCPs. Three clones of TvCP4 genes, GZ-CP4-clone 1-3, belonged to two members of a family showing a high percentage identity of more than 97.5% with the sequences of TvCP4 genes from databases (GenBank and TIGR) both at amino acid and nucleotide levels. Nine homologous TvCP4 pro-enzymes with 304 amino acids and other two members with deletions of N-terminal sequence existed in T. vaginalis sharing a similarity of 62.3-96.7% amino acids, which may evolve by means of gene replication and deletion. TvCP1-4, TvCP12, TvCP25 and CP65 had an identity of 61-88.2% at amino acid levels. So far, all reported sequences of C1 family from T. vaginalis belonged to capanthesin L-like subfamily with the same enzymatic active sites, conserved cysteine residues and similar structural features such as ERFNIN-like motif in pro-enzyme region, suggesting that they might result from gene duplication and mutations. Conclusion TvCPs belong to cathepsin L-like family with genetic diversity, but they have the same active amino acid residues, cysteine residues and similar structural characteristics, suggesting that they may derive from one ancestor.

Objective To explore the clinical features of systemic onset of juvenile idiopathic arthritis (SoJIA) with atlantoaxial subluxation as the initial manifestation. Methods The clinical data from one SoJIA patient with atlantoaxial subluxation as the initial manifestation were retrospectively analyzed. Results A 9-year-old boy presented the head and neck movement disorder as the ifrst symptom, developed fever on the third day, then rapidly progressed on 23rd day, with a sharp decline in red blood cell, platelet, and hemoglobin, blood coagulation dysfunction, and a large number of bilateral pulmonary exudation. Ultrasonography showed excess lfuid in abdomen, chest, and pericardium. According to the 2001 version of the revised International College of Rheumatology standard, the diagnosis of SoJIA combined macrophage activation syndrome was conifrmed. Then treated with hemoperfusion, ifltration, and methylprednisolone combined with cyclosporine A, the disease was in remission. Conclusion For children with spontaneous atlantoaxial subluxation accompanied by the systemic symptoms, with no obvious skeletal deformity or acute inlfammation etc., should be alerted to the consideration of systemic juvenile idiopathic arthritis.

Objective To analyze the clinical and ultrasonic features of primary squamous cell carcinoma of the thyroid(PSCCT)and diagnostic value of ultrasonography (US) in PSCCT in order to improve the cognition of PSCCT.Methods The clinical data and ultrasonic characters of 5 patients with PSCCT confirmed by pathology post surgery were retrospectively reviewed.Results The average age of the 5 patients was 62 years (range from 46 to 79).All of 5 patients with PSCCT were presented with a painless neck mass in clinical palpation examination.Of them,2 patients had different degrees of difficulty in breathing and swallowing,2 patients had hoarseness.Four of 5 patients had died after surgery with average survival time of 9.5 months.On US,the size of lesions was large(a maximum diameter of 2.9-5.5 cm),all of 5 lesions appeared as single solid mixed-echogenicity mass including irregular lamellate marked hypoechoic region,with irregular margin and undefined boundary.Of them,2 lesions presented with lobulated,only 1 lesion exhibited microcalcification and another 4 lesions had no calcification,3 lesions exhibited a? sign of breakthrough thyroid envelope.Color Doppler flow imaging showed few blood flow (3/5) and moderate blood flow (2/5),a higher vascular resistance spectrum was detected in 4 lesions (RI 0.72-0.88).Three patients exhibited suspicious cervical lymph nodes.Conclusions The characteristic ultrasonic appearance combined with the clinical features enables a confident preoperative diagnosis of PSCCT.

0.05).Conclusion High level of Blys could be observed in serum of patients with SLE and somewhat correlated with the lupus acitivity,although the level of Blys in serum can not reflect morbility and mortality of SLE patients.

BACKGROUND:Among the factors causing vascular endothelial cell injury,angiotensin Ⅱ(Ang Ⅱ) caused by renin-angiotensin system (RAS), especially by local RAS, plays an important patho-physiological role.OBJECTIVE: To observe the effect of tanshinone ⅡA on the vascular endothelial cells secreting nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) gene expression as well as intracellular Ca2+ level induced by Ang Ⅱ, and investigate the protective effect of tanshinone ⅡA on vascular endothelial cells.DESIGN: Controlled observation experiment.SETTING: Department of Emergency, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: This experiment was carried out in the Experimental Center for Basic Medicine, Tongji Medical College,Huazhong University of Science and Technology from March 2006 to October 2006. Porcine aorta used in this experiment was provided by the Department of Pathophysiology of Tongji Medical College.METHODS: Nitric acid deoxidization method and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the effects of Ang Ⅱ of different concentrations (10-8 to 10-6 mol/L) on endothelial cells secreting NO and eNOS mRNA expression in cultured porcine aortic endothelial cells at different time points (1,6 and 24 hours) separately, then 50 mg/L tanshinone Ⅱ A was respectively added at different time point (0, 6 hours) when Ang Ⅱ was at 10-6 mol/L, and changes in NO production and eNOS gene expression were detected respectively at 1, 6 and 24 hours. Intracellular Ca2+ level was also detected with laser scanning confocal microscopy.MAIN OUTCOME MEASURES: ① NO content. ②eNOS mRNA expression. ③Intracellular Ca2+ level.RESULTS: ① NO production and eNOS mRNA expression were decreased with increase of Ang Ⅱ concentration and prolongation of time (P ＜ 0.01). ② NO production and eNOS mRNA expression in each tanshinone ⅡA-treated group were significantly higher than those in the Ang Ⅱ group. At 1 and 6 hours of tanshinone ⅡA treatment, production of NO and eNOS mRNA expression in the Ang Ⅱ + tanshinone ⅡA group were significantly higher than those in the Ang Ⅱ 6 hours + tanshinone ⅡA group (P ＜ 0.05); There were no significant differences in NO production and eNOS mRNA expression between two groups at 24 hours (P ＞ 0.05). ③Intracellular Ca2+ level in the Ang Ⅱ group was significantly higher than that of control group (P ＜ 0.01), and intracellular Ca2+ level in the tanshinone ⅡA + Ang Ⅱ was significantly lower than that in the Ang Ⅱ group (P ＜ 0.05).CONCLUSION: Tanshinone Ⅱ A has a protective effect on vascular endothelial cells and their functions by suppressing the inhibition of Ang Ⅱ on NO level and eNOS gene expression in cultured porcine aortic endothelial cells.
