This study proposed to use Term Frequency - Inverse Document Frequency (TF-IDF) relative entropy as knowledge representation method between symptoms and syndrome. TF-IDF was originated from text mining. It was an important method in the automatic text categorization. TF-IDF also represented the automatic categorization idea in traditional Chinese medicine (TCM) syndrome. It was based on the fact that the higher frequency of one symptom in specific syndrome, the stronger ability to distinguish this syndrome (TF); and the more wide range of one symptom in all syndrome, and the lower ability to distinguish a syndrome (IDF). It was verified with specific examples.

AIM: To investigate the effects of aging on the angiotensinⅡ receptors (ATR) in different parts of the kidney. METHODS: Expression of AT 1 receptor in renal cortex was determined by Western and Northern blotting. Five micrometer thick cryostat sections of 3 or 24-month Wistar rats were mounted onto a 1.35?m thin polyethylene membrane. Glomeruli, tubules and arteries of rat kidney were isolated by laser microdissection and pressure catapulting system, AT 1aR mRNA, AT 1bR mRNA AT 2R mRNA were measured with reverse-transcription PCR(RT-PCR). RESULTS: Western and Northern blotting showed that protein and gene expression of AT 1 receptor in kidney cortex decreased in 24 month Wistar rats compared to those in 3 month Wistar rats. Glomeruli, tubules and arteries were quickly isolated by laser microdissection and pressure catapulting system without contamination. Compared to young group, AT 1aR mRNA expression was decreased in the tubules of aged rats, no changes was found in isolated glomeruli. AT 1bR mRNA was decreased in glomeruli and tubules. Both AT 1aR mRNA, AT 1bR mRNA were increased in the arteries. AT 2R mRNA was only increased in the tubules, whereas there were no significant changes in the glomeruli or arteries. CONCLUSION: Angiotensin Ⅱ receptors are regulated selectively in different portions of aged kidney, which might play an important role in aging related changes of the kidney.

Objective To evaluate the feasibility of monitoring the gene expression of VEGF165 via the diglycylcysteine (GGC) reporter gene system by reporter probe of 99Tcm-GH. Methods DNA fragments encoding GGC binding motifs were prepared by PCR and positioned at the C end of VEGF165 gene after the linearization of pcDNA3-VEGF165 plasmid. A replication-defective adenovirus vector Ad5-VEGF165GGC motif-internal ribosomal entry site(IRES) -enhanced green fluorescent protein (EGFP) (Ad5-VIE)was constructed, with a cytomegalovirus (CMV) early promoter driving the expression of VEGF165 gene,GGC motif and EGFP, under the aid of an IRFS. A replication-defective adenovirus carrying the Ad5-EGFP was used as the control. Mensenchymal stem cells (MSC) were infected with the recombinant adenovirus at a multiplicity of infection (MOI) from 0 to 100 infectious units (0,10,25,50,100). The cellular uptake of 99Tcm-GH in infected MSC were then studied at 30, 60, 90 and 120 min. VEGF165 was detected by quantitative reverse transcriptase real-time PCR (RT-PCR), Western-blot, and immunohistochemisty. EGFP was observed by RT-PCR and fluorescence microscopy. The correlation analysis was studied between the cellular uptake of 99Tcm-GH and the expression of VEGF165. SPSS 13.0 was applied for statistical analysis. Independent samples t-test, q-test and Pearson correlation coefficient were used. Results After infected with different viral titer of Ad-VIE, the cellular uptake of 99Tcm-GH increased with the increasing virus titer(r2 =0.86, P ＜0.05), with the peak rate (7.94 ±0.75) % at MOI = 100. In time-dependent uptake study, the cellular uptake rates increased rapidly with the time extension, and the highest uptake occurred at 120 min with the peak uptake rate (7.72 ±0.22)%. The uptake rates of 99Tcm-GH in Ad5-VIE-infected cells were significantly higher than those of Ad5 -EGFP-transfected cells at all time points (t = 15.10- 54.92, all P ＜0.05). The VEGF165 and EGFP mRNA levels increased with increasing virus titer, and the VEGF165 mRNA correlated well with the EGFP mRNA(r2 = 0. 99, P ＜ 0.05). After infected with different MOI of Ad5-VIE, good relationship was found between the cellular uptake of 99Tcm-GH and the expression of VEGF165protein in MSC(r2 =0.90, P ＜0.05). Inmunohistochemisty showed VEGF165 protein expressed obviously at Ad5-VIE-infected MSC, and the EGFP was observed by fluorescence microscopy. Conclusions The cellular uptake of 99Tcm-GH in Ad5-VIE-infected MSC are well correlated with the expression of VEGF165 in vitro. The expression of therapeutic gene VEGF165 can be monitored by the GGC peptide expression.

OBJECTIVETo compare the clinical effects between hip anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery and posterior K-L approach combined with quadratus femoris bone flap transplantation for the treatment of femoral neck fracture of Garden III-IV in young and middle-aged patients.

METHODSFrom January 2004 to January 2011,46 patients with femoral neck fractures were treated by two kinds of operation. Among them, 20 cases were treated with anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery, included 12 males and 8 females with an average age of (32.1 ± 7.3) years old, involved 12 cases of Garden III and 8 cases of Garden IV. The other 26 cases were treated with posterior K-L approach combined with quadratus femoris bone flap transplantation, included 20 males and 6 females with an average age of (37.8 ± 6.9) years old, involved 16 cases of Garden III and 10 cases of Garden IV. The index of hospitalization (hospitalization time, total cost, operative time, intraoperative blood loss, postoperative complications), the quality index of operation (fracture reduction, position of internal fixation, fracture healing time, nonunion and femoral head necrosis) of two groups were observed and compared. Hip joint function were evaluated by Harris score.

RESULTSAll patients were followed up from 28 to 41 months with an average of 36 months. The intraoperative blood loss of group S-P (92.3 ± 10.4) ml was less than that of group K-L (132.4 ± 11.2) ml, there was significant difference between two groups (P < 0.05). The operation time of group S-P (81.4 ± 9.2) min was more than that of group K-L (67.1 ± 4.5) min, the difference was statistically significant (P < 0.05). One case in group S-P and 9 cases in group K-L appeared postoperative complications, there was significant difference between two groups (P < 0.05). The fracture healing time of S-P group (83.5 ± 7.3) d was shorter than that of group K-L (103.2 ± 12.6) d, there was significant difference between two groups (P < 0.05). At 30 months after operation, there were significant difference in Harris scoring between two groups (P < 0.05).

CONCLUSIONAnterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery for treatment of femoral neck fracture of Garden III-IV of young and middle-aged patients, it has characteristics in clear anatomic and easy to operate. As compared with K-L approach, S-P approach can better reserve residual blood supply of femoral neck. While combining with the iliac bone flap transplantation with deep circumflex iliac artery, it could better reconstruct the blood supply of femoral neck to promote fracture healing.
