Objective To review the clinical management of the radial nerve palsy (RNP) associated with humeral shaft fractures via systematically reviewing the published available articles, and develope an algorithm to guide management for RNP. Methods Using PubMed, Datastar and Cochrane Database, web based databases were searched for radial nerve palsy associated with humeral shaft fractures in the past 40 years, and manual searches of the bibliographic sections of electronically identified papers were done to identify further papers. Meticulous data extraction and meta-analysis was performed according to a preset protocol. Results In 391 citations initially identified, 35 papers, which included a total of 1045 RNP patients, met all eligibility criteria. The overall RNP incidence after humeral shaft fractures in 21 papers was 11.8% (532/4517). The incidence of RNP in middle 1/5 and middle-distal 1/5 of the humeral shaft fracture was significantly higher than that in other parts. Transverse and spiral fractures were more likely to sustain RNP than oblique and comminuted fracture patterns(P

Objective To evaluate the effectiveness of laparoscopy in anterio r lumbar interbody fusion. Methods Twenty-three laparoscopic anterior lumbar int erbody fusions were performed in the period between December 2000 and December 2 002. There were 9 males and 14 females with a mean age of 52 years (range, 46 to 66 years). In this group, there were 18 of spondylolisthesis, 3 of lumbar spina l instability and 2 of degenerative disc treated with anterior lumbar interbody fusion using Syncage and autograft with balloon-assisted endoscopic extraperiton eal gasless exposure. The main complaints were low back pain radiating to leg. 1 3 cases were fused at L4,5 and 10 at L5S1. The Oswestry Disability Index (ODI) w as recorded to evaluate the function preoperatively, and in the 2nd week, 3rd, 6 th and 12th month postoperatively. X-ray was taken to observe the fusion and the subsided cage. Results The operative time ranged from 50 to 180 min with a mean of 120 min, and the bleeding volume ranged from 50 to 300 ml with a mean of 80 ml. There were complications in 2 cases, one which was caused by laparoscopic mi sguidance, and the other was bleeding due to a small vessel injury. All the case s were followed-up from 12 to 24 months, with a mean of 16.6 months. The ODI was found with significant difference comparing preoperatively to at 2nd week, 3rd, 6th and 12th month postoperatively (P

Objective To analyze the associations of the interleukin-10 (IL-10) promoter-1082G/A and-819C/T single nucleotide polymorphism (SNP) and serum level of IL-10 with intracranial aneurysm (IAs). Methods The polymerase chain reaction (PCR) and DNA direct sequencing methods were used to detect IL-10 gene promoter district two SNP site,-1082G/A and-819C/T genotype frequency and allele frequency in 206 patients with IAs and 187 controls. Chi-square test was used to analyze differences between two groups. The serum level of IL-10 was analyzed by ELISA, and t-test was used to analyze significant differences between two groups. Results There were significant differences in genotypes of GG and GA+AA, as well as the alleles G and A, in-1082G/A locus between IAs group and control group (P<0.01). There were higher frequencies of genotype GA+AA and the allele A in IAs group than those in control group (P<0.01). There was higher risk of suffering IAs in patients with genotype GA+AA (OR=4.137, 95%CI:2.476-6.914) and the allele A (OR=3.368, 95%CI:2.476-4.583). There were higher frequencies of the genotype CT+TT and the allele T in-819C/T locus in IAs group than those of control group (P<0.01). There was higher risk of suffering IAs in patients with genotype CT+TT (OR=3.393, 95%CI:1.952-5.900) and the allele T (OR=3.764, 95%CI:2.730-5.192). The serum level of IL-10 was significantly lower in IAs group than that of control group (P<0.01). Conclusion The IL-10 promoter SNP influences the expression of IL-10. IL-10 promoter-1082G/A and-819C/T polymorphisms are correlated with the formation of IAs.

To evaluate the absorptive characteristics of furfural onto biomass charcoals derived from rice husk pyrolysis, we studied the information of the structure and surface chemistry properties of the rice husk charcoals modified by thermal treatment under nitrogen and carbon dioxide flow and adsorption mechanism of furfural. The modified samples are labeled as RH-N2 and RH-CO2. Fresh rice husk charcoal sample (RH-450) and modified samples were characterized by elemental analysis, nitrogen adsorption-desorption isotherms, Fourier-transform infrared spectroscopy and Boehm titration. The results show that fresh rice husk charcoal obtained at 450 degrees C had a large number of organic groups on its surface and poor pore structure. After the modification under nitrogen and carbon dioxide flow, oxygenic organics in rice husk charcoals decompose further, leading to the reduction of acidic functional groups on charcoals surface, and the increase of the pyrone structures of the basic groups. Meanwhile, pore structure was improved significantly and the surface area was increased, especially for the micropores. This resulted in the increase of π-π dispersion between the surfaces of rice husk charcoals and furfural molecular. With making comprehensive consideration of π-π dispersion and pore structure, the best removal efficiency of furfural was obtained by rice husk charcoal modified under carbon dioxide flow.
