Objective To investigate the effect of rosiglitazone on renal interstitial fibrosis in chronic cyclosporine nephropathy (CCN) rats.Methods Twenty-eight rats were randomly assigned to control group,rosiglitazone (RGZ,5 mg·kg-1·d-1) group,cyclosporine A(CsA,15 mg·kg-1·d-1) group,rosiglitazone (5 mg·kg-1·d-1) +CsA group.Real-time PCR and RT-PCR methods were used to investigate the expressions of OPN,RANTES on the 14th day and MMP-9,TIMP-1 on the 35th day in kidney of CCN respectively.Results In comparison with control group,the expressions of OPN,RANTES,MMP-9,TIMP-1 in CsA and RGZ+CsA groups were increased (P＜0.05).In comparison with the CsA group,the expressions of OPN,RANTES,MMP-9,TIMP-1 in CsA+RGZ group significantly decreased (P＜0.05).Conclusion Rosiglitazone may protect renal tissue after CCN by decreasing expressions of OPN,RANTES,MMP-9,TIPM-1.

Objective To explore the feasibility of artificial silastic framework(SF)in repair of large area of tracheal wall defects.Methods Twenty healthy adult dogs with tracheal defects for 2.5 cm?6.0 cm-3.0 cm?6.0cm were randomly and equally divided into experimental group(repaired with SF combined with sternohyoid fasciae)and control group(repaired with T-silastie tubule combined with sternohyoid fascial flap).After the operation,the animals were sacrificed at the 4th,8th,16th,24th, and 48th weeks respectively for harvesting the tracheae that were used for tracbeoscopically observing in- flammatory reaction of the repaired defect area and light microscopically observing epithelium healing on the repaired defect area.Results In the experiment group,the repaired trachea was smooth,without proliferation of granulation;and at the 8th week,the repaired defect area was covered with epithelial cells,with good functional recovery of respiration,phonation and deglutition.In the control group,there was obvious proliferation of granulation on the tracheal surface near anterior and posterior ends of T-silas tic tubule.The animals were under asphyxia to die with extraction of T-silastic tubule.Conclusions SF has excellent tracheal skeletal function.In the meantime,SF combined with sternohyoid fasciae is a simple but effective method for repair of large area of tracheal wall defects.

OBJECTIVETo summary the characteristics of cervicothoracic junction (C7T1) fracture-dislocation,and explore the surgical treatment of combined anterior-posterior procedure.

METHODSFrom January 2005 to March 2010,8 cases of cervicothoracic junction (C7T1) fracture-dislocation were treated by stage I operation through anterior and posterior approacheg, supplemented by non-structural bone graft. All patients were male with a mean age of 45.0 years old ranging from 32 to 68 years. Six cases were diagnosed clearly by CT scan but with normal cervical spine X-ray film at admission. According to AO classification, 4 cases were of type B, 4 cases of type C, with unilateral locked articular process in 2 cases, bilateral in 2 cases. Preoperative MRI showed intervertebral disc injury in 6 cases.

RESULTSThe average operation time was 246.3 min ranging from 150 to 320 min. The blood loss was with an average of 307.5 ml (150 to 600 ml). One patient got hoarseness but recovered without special treatment 6 months later; No other complications happened. One patient of preoperative Frankel grade A died, the remaining patients were followed up from 12 to 63 months (38.6 months in average). These fracture-dislocations were completely reduction after operation, healed with bony union 12 months later, and no pseudoarthrosis. The function of the spinal cord improved obviously at the final follow-up, 1 patient of preoperative grade A had died,and the spinal cord function of the other one had no significant changes,the 2 cases of grade B recovered to C and D respectively, 1case recovered from grade C to D, and 3 case recovered from D to E.

CONCLUSIONCervicothoracic junction (C7T1) fracture-dislocation is a rare clinical spine trauma, and missed easily. The CT is a necessary complement to these patients highly suspected C7T1 fracture-dislocation but with negative cervical spine X-ray film. The patients diagnosed clearly could receive stage I operation of anterior and posterior approaches, supplemented with non-structural bone graft.

In this study, efforts were made to collect 88 traditional Chinese medicine (TCM) prescriptions for treating ADHD from public literatures, establish a medication database and conduct data mining on the efficacy, properties, tastes, meridian entries and compatibility regularity of TCMs by using frequency analysis, association rules analysis and cluster analysis. The results showed 33 herbs with a high frequency (≥ 10%). The top 12 frequently applied ADHD herbs were respectively Acori Tatarinowii Rhizome, Polygalae Radix, Prepared Rehmanniae Radix, Os Draconis, Glycyrrhizae Radix et Rhizome, Poria, Concha Ostreae, Testudinis Carapacis et Plastri, Paeoniae Alba Radix, Schisandrae Fructus Chinensis, Fructus Corni, Dioscoreae Rhizoma. The top seven types of frequently applied ADHD herbs by effect were respectively tonic herb, sedative herbs, livei-wind calming herbs, heat clearing herbs, astringent herbs, awaking herbs and damp clearing and diuresis promoting herbs. The top three properties were warm, cold and neutral, with warm as the dominance. The top three tastes were sweetness, bitterness and acridity, with sweetness as the dominance. The top three meridian entries were liver meridian, heart meridian and kidney meridian. The association rules analysis showed commonly used herbal pairs. Polygalae Radix-Acori Tatarinowii Rhizome, Concha Ostreae-Os Draconis, Prepared Rehmanniae Radix-Fructus Corni-Os Draconis. Eight highly frequent cluster prescriptions were summarized based on the cluster analysis. This study indicates that basic TCM prescriptions for treating ADHD were principally composed of tonics (nourishing liver and kidney, invigorating heart and spleen) and tranquilization, which were supplemented with herbs for calming liver, clearing heat, promoting qi-circulation, promoting blood-circulation, reducing phlegm and calming endogenous wind. The combination of multiple data mining techniques can reflect the clinical medication regularity of herbs for treating ADHD in an overall and objective manner.

Objective: To analyze the survival rate of stomach cancer patients and its variation during different periods in Linzhou city, Henan Province, from 1988 to 2004, and evaluate the level of secondary prevention and diagnosis of stomach cancer in this area. Methods: All of the incidence and death records of stomach cancer from 1988 to 2004 were collected and matched from Linzhou Cancer Registry. The records that were identified as duplicate cases or had only death certificate (DCO) were excluded. The tumor cause eliminated life tables in this area were calculated and linked to the data of incidence and death of stomach cancer. FivE-year observed survival rates and fivE-year relative survival rates in three periods (1990-1994, 1995-1999, and 2000-2004) were calculated using period survival analysis mehod. The relative survival curves in the three periods were plotted. Results:The 5-year relative survival rate of stomach cancer was 26.66% during 1990-1994, 32.01% during 1995-1999, and 40.43% during 2000-2004 in Linzhou city. It showed a gradually increasing trend. The 5-year survival rates were higher in males than those in females. During 1990-1994 and 1995-1999, the 5-year survival rates of gastric cardia cancer were higher than those of non-cardia cancer. During 2000-2004 period, the 5-year survival rate of gastric cardia cancer was lower than that of non-cardia cancer. Conclusion: The survival rates of stomach cancer in Linzhou city are increasing gradually since 1990s in 20 century. It indicates that the levels of secondary prevention and clinical diagnosis and treatment on stomach cancer kept increasing in this area.

AlM: To investigate expressions of matrix metalloproteinase-2 ( MMP-2 ) and extracellular matrix metalloproteinase inducer ( EMMPRlN) in retinoblastoma (Rb) and the relationships between MMP-2, EMMPRlN and tumor development.METHODS:lmmunohistochemical technique was used to detect expressions of MMP-2 and EMMPRlN in 39 cases of paraffin embedded Rb samples. Quantitative analysis of expressions of MMP-2 and EMMPRlN were assessed by measuring the mean gray scale of Rb tissue with LElCA lM50 Color Pathologic Analysis System. The differences of expressions of MMP-2 and EMMPRlN in each clinical and pathological stage were statistically analyzed, and the same step was also undertaken to study the relationship between Rb with MMP-2 positive expression and that with EMMPRlN positive expression.RESULTS:The positive expression rate of MMP-2 was 90% (Gray value: 109. 64 ± 14. 52; 35/39), and that of EMMPRlN was 85% (Gray value:108. 01±13. 60;33/39). The expressions of MMP - 2 and EMMPRlN were significantly higher in tumors of glaucomatous stage (Gray value:108. 21±11. 47 and 107. 56±14. 32) than those in intraocular stage ( Gray value: 121. 13 ± 11. 32 and 119. 34 ± 12. 66; P<0. 01 and P<0. 05). And the same conclusion can be concluded between those in extraocular stage (Gray value: 91. 03 ± 11. 71 and 92. 26 ± 12. 93) with those in glaucomatous stage (P<0. 01 and P<0. 05). The expressions of MMP-2 and EMMPRlN were significantly higher in tumors with optic nerve invasion (Gray value:103. 89±13. 39 and 105. 23±14. 00) than those without optic nerve invasion ( Gray value: 118. 39 ± 15. 11 and 117. 53±16. 13) (P<0. 01 and P<0. 05).CONCLUSlON:The positive expression levels of MMP-2 and EMMPRlN may correlate with tumor infiltration and metastasis.
