Objective To investigate the effect of penehyclidine hydrochloride ( PHC) pretreat?ment on nuclear factor erythroid 2?related factor 2∕heme oxygenase?1 ( Nrf2∕HO?1) signaling pathway in re?nal tissues of rats with rhabdomyolysis?induced acute kidney injury ( AKI) . Methods Thirty?six pathogen?free male Sprague?Dawley rats, weighing 200-220 g, were assigned into 3 groups ( n=12 each) using a random number table: control group (group C), group AKI and PHC pretreatment group (group PHC). Rhabdomyolysis was induced by intramuscular injection of 50% glycerol 10 ml∕kg in bilateral hindlimbs. PHC 0?2 mg∕kg was injected intraperitoneally at 30 min before glycerol was injected intramuscularly in group PHC. At 1 and 6 h after glycerol injection, serum was collected for determination of blood urea nitro?gen ( BUN) and creatinine ( Cr) concentrations, and bilateral kidneys were harvested for pathological ex?amination and for determination of HO?1 activity and expression of Nrf2 mRNA and HO?1 mRNA ( by quan?titative real?time polymerase chain reaction) , Nrf2 in nucleoprotein and total protein and HO?1 in total pro?tein in renal tissues ( by Western blot) . The damage to the renal tubules was scored. Results Compared with group C, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly increased, the expression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was signifi?cantly up?regulated, and HO?1 activity was significantly increased in AKI and PHC groups, the expression of HO?1 mRNA was significantly up?regulated in group AKI, and the expression of Nrf2 mRNA and HO?1 mRNA was significantly up?regulated in group PHC (P<0?01 or 0?05). Compared with group AKI, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly decreased, the ex?pression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was significantly up?regulated, and HO?1 activity was significantly increased in group PHC ( P<0?01 or 0?05) . Conclusion The mecha?nism by which PHC pretreatment attenuates rhabdomyolysis?induced AKI may be related to activation of Nrf2∕HO?1 signaling pathway in renal tissues of rats.

Objective To investigate clinicopathologic characteristics of obsolete Bennett fractures and their surgical treatment and prognosis. Methods From August 2008 to April 2010,13 patients with obsolete Bennett fracture were admitted to our department.They were 12 men and one woman,with an average age of 34.3 years (from 17 to 42 years).They had a fracture history of over 4 weeks to as long as 12 weeks (average,7.9 weeks).In all patients,after X-ray examinations,the radio-dorsal ligament complex of the first carpometacarpal joint was properly released,fracture gaps were cleared up,fracture fragments were anatomically reduced and fixed with a Kirschner wire,and at last the first metacarpal joint was fixed with the Kirschner wire crossing the joint Postoperatively all patients were immobilized with cast plaster for 4 weeks before the Kirschner wires acrross the joint were removed.Gradual rehabilitation was conducted.The X-rays were taken every month. Results The patients were followed for 6 to 24 months(average,14 months).The fractures healed in all the patients,with an average healing time of 3 months.No dislocation of the joints occurred.Injury to articular cartilage of the trapezium bone occurred in one patient,and no apparent pain was experienced in the other 12 patients.According to the Total Active Motion assessment,the thumb function was rated as excellent in 9 cases,good in 2,moderate in one and poor in one,with a good to excellent rate of 84.6％.Conclusions In obsolete Bennett fractures,the radio-dorsal ligament complex of the first carpometacarpal joint will have cicatricial contracture,preventing reduction of the fragments of the radio-dorsal joint.Therefore it is important to properly release the radio-dorsal ligament complex to achieve anatomical reduction of the radio-dorsal joint.An injury history of over 3 months and complicated injury to the trapezium bone cartilage may be significant factors affecting the prognosis of obsolete Bennett factures.

Conclusion Medial plica syndrome of the knee constitutes a larger proportion of knee disorders, for which arthroscopy re-mains the best diagnostic option and total excision of the diseased plica synovialis is an effective treatment .

Objective To study the relationship of clinical manifestation and pathological changes and prognosis in Henoch-Schonlein purpura nephritis(HSPN)in children.Methods Clinical and pathological characteristics of 42 children with HSPN were analysed.Among them,40 children were detected of angiotensin-convertion enzyme(ACE)gene and had been followed up.Results Among them,there were 9 cases of level Ⅰof pathological types,21 cases of level Ⅱ,12 cases of level Ⅲ,but no cases of level Ⅳ.Ⅰand Ⅱ level were found in those cases of clinical manifestation with solitary hematuria and albuminuria.Pathological grades were Ⅰ,Ⅱ and Ⅲ levels in the cases of hematuria and albuminuria.Pathological types of nephrotic syndrome(NS)were Ⅱ and Ⅲ level,which were of more gross hematuria than those of other grades.ACE gene DD had serious pathological damnification.Conclusions Change of pathology cannot only be anticipated by clinical manifestation of HSPN.But if pathological damnification gets more serious,the albuminuria gets more serious.Gross hematuria and albuminuria can serve as indicators of biopsy.NS of ACE DD type have serious pathological damnification.Children with HSPN has favourable prognosis in the future.

italic>Alangium chinense is a commonly used medicinal plant of Alangiaceae Alangium, one of the characteristic Miao medicines in Guizhou. The genus is strongly differentiated and has complex morphological variation, with significant differences in active ingredients and potency among herbs. In this paper, we sequenced the chloroplast genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib using Illumina high-throughput sequencing technology. The genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplasts were sequenced, their assembly annotation and structural characterization were completed, and the genomes of the congeners Alangium chinense and Alangium alpinum were downloaded from NCBI for comparative analysis. Finally, the phylogenetic tree was constructed by selecting published species with close affinity to Alangium chinense family from NCBI. The results were as follows: Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplast genomes were 156 670, 156 672 and 156 871 bp in length, with a typical four-segment structure, all containing one long single copy region (LSC), one short single copy region (SSC) and two inverted repeat regions (IRa and IRb). All of them were annotated to 133 genes, including 88 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Three types of long repeat sequences and SSR loci, forward repeats, palindrome repeats and reverse repeats, were found in all chloroplast genomes. Comparative genomic analysis showed that there was diversity in the boundary transition regions of the five species, no rearrangements or inversions were found in the chloroplast genome, and there were significant differences in the coding regions of ndhA, ycf1, rpl16, ycf2, and petD genes, which provided new loci for molecular identification of Patagonia. In the phylogenetic analysis, Alangium kurzii var. kurzii clustered as a single species, and Alangium chinense subsp. Pauciflorum and Alangium chinense subsp. Strigosum clustered as a single species, with a support rate of 93 and close affinity, indicating that the phylogenetic tree can be used for the species identification. This paper can provide a basis for the taxonomic identification of Alangium, ensure the safety of clinical use of anise herbs and regulate the market of Alangium chinense herbs.
