OBJECTIVETo evaluate the intermediate and long-term follow-up effect of posterior dynamic lumbar stabilization in lumbar degenerative disease.

METHODSThe clinical outcomes of 96 patients (male 51, female 45, age from 21 to 68 years, mean 41.5 years) whose follow-up time were more than 2 years with lumbar degenerative disease treated by posterior decompression with Wallis posterior dynamic lumbar stabilization implant or combined with posterior lumbar fusion from August 2007 to January 2010 were retrospectively studied, and assessed with visual analogue scale (VAS) and spinal operative standard of Chinese Medical Association. The early and long-term follow-up effect and complications associated with Wallis posterior dynamic lumbar stabilization were recorded. The height of intervertebral space at the treated level in lateral plain film were measured at preoperatively, 3 month postoperatively and last follow-up, respectively. The finds of MRI obtained at over 6 month postoperative were recorded.

RESULTSThe operative procedure of Wallis posterior dynamic lumbar stabilization implant was easy and less invasive. The VAS scores were 78 ± 24, 28 ± 16 and 14 ± 12 preoperatively, 3 month postoperatively and last follow-up, respectively. The good or excellent result was 91.7% at the last follow-up. No complication related with Wallis posterior dynamic lumbar stabilization was found. The rate of patient's satisfaction with the Wallis implant operation was 95.8%. The disc height at the treated level in lateral plain film were (8.2 ± 3.7), (10.4 ± 2.6) and (10.1 ± 1.9) mm at preoperatively, 3 month postoperatively and last follow-up, respectively. There is no further degenerative change found in MRI obtained at over 6 month postoperative. MRI 1 year after Wallis procedure showed rehydration of the formerly black disc at the treated level.

CONCLUSIONSIt is easy and safe to use Wallis posterior dynamic lumbar stabilization in treatment of degenerative lumbar disease, and the effect of the intermediate and long-term follow-up more than 2 years is good. The Wallis system provides an alternative for treatment of lumbar degenerative disease.

Rsm (repressor of secondary metabolite) A is an mRNA binding protein which functions as a global repressor to control multiple genes at the posttranscriptional level. Using homologous recombination technique a chromosomal rsmA inactivated mutant strain M-18R was constructed in Pseudomonas sp. M-18, a strain of plant-growth-promoting rhizobacteria, which could inhibit several soilborn phytopathogens by producing secondary metabolites including phenazine-1-carboxylic acid (PCA) and pyoluteorin (Plt) in one single strain. To further study the effect of RsmA on the synthesis of Plt and PCA in the wild type strain M-18, the dynamic curves of Plt and PCA produced respectively by M-18 and M-18R were measured in KMB medium under different temperature conditions such as 37 degrees C constant, 28 degrees C constant and nonconstant (37 degrees C 4 hours at first and then 28 degrees C constant) cultivation. The synthesis of both Plt and PCA were almost inhibited in the cultures under the condition of 37 degrees C. At 28 degrees C, however, compared with the wild type strain M-18, the mutant strain produced tenfold amount of Plt, while the production of PCA decreased only about 50%. When cultivated under the nonconstant condition, the amount of Plt produced by M-18R could reach 400 microg/mL while the PCA production was not significantly affected, but in the wild type strain M-18, the amount of Plt production decreased obviously while the PCA production was not affected in comparison with the results at 28 degrees C constant. These results suggest that a temperature sensitive factor exists to function as an activator independent of RsmA to promote the synthesis of Plt in the rsmA mutant strain M-18R while it may bind with RsmA to repress the synthesis of Plt in the wild type strain M-18. But this factor did not exert any affect on the synthesis of PCA.

Objective To explore whether autoreactive antibody presents in patients with sporadic idiopathic hypoparathyroidism(sIHP).Methods The subjects including 26 patients with sIHP and 112 genealogical members as well as 60 age-and sex-matched healthy controls.Anti-parathyroid antibodies in the sera were assayed by indirect immunofluorescence.The levels of calcium,phosphorus and magnesium as well as intact parathyroid hormone(iPTH)in the sera were tested.Results Positive autoantibodies against parathyroid tissue were demonstrated in 10 patients(38%)with sIHP,significantly higher than that of in genealogical members(10%,?~2=13.42,P

AIM To study the influence and action mechanism of effective components in compatible solution of Sparganii Rhizoma-Curcumae Rhizoma on pelvic adhesions of model rats with chronic pelvic inflammatory disease.METHODS Laboratory rats were randomly assigned into six groups,a sham-operated group,a model group,a positive Fukeqianjin tablets group,compatible solution groups (40 g/kg high-dose group,20 g/kg medi um-dose group,and 10 g/kg low-dose group).Except rats of the sham-operated group,those in the other groups were induced into models of chronic pelvic inflammatory disease by mechanical bacterial strain implantation,after which a 20 d corresponding drug administration by oral gavage for each group was initiated.After completion of the last drug administration,Verco criterion was taken as the reference to evaluate pelvic adhesions,HE staining was performed on uterine tissues for pathological scoring,ELASA method was applied to measuring serum IL-1β and TNF-α levels,and Western blot method was used to detect the expression levels of proteins FGF-2 and IGF-1 in uterine tissues.RESULTS Compared with the model group,the high-dose compatible solution group had a much sharper fall in Verco scores (P ＜ 0.05),and remarkably decreased serum IL-1β and TNF-α levels (P ＜ 0.01);both high-dose and medium-dose groups manifested with notably alleviated degenerative necrosis and lowered scores of chronic inflammation infiltration and epithelial hyperproliferation (P ＜ 0.01 or P ＜ 0.05),and a distinct reduction in the expression of proteins FGF-2 and IGF-1 (P ＜ 0.05,P ＜ 0.01).CONCLUSION The significant improvement of the chronic pelvic inflammatory disease in model rats due to the effective components in the compatibile solution of Sparganii Rhizoma-Curcumae Rhizoma may be associated with inhibited release of inflammatory mediators IL-1β and TNF-α,and the reduced expression of proteins FGF-2 and IGF-1 as well.

BACKGROUNDMethylmalonic acidemia (MMA) is a multifactorial autosomal recessive inborn error of organic acid metabolism, often presenting with neurological symptoms. As neurological disorders are often related to white matter injury, diffusion tensor imaging (DTI) is an excellent tool for assessment of white matter injury and possibly for diagnosing this disorder.

METHODSWe retrospectively analyzed DTI images of 12 patients with MMA (7 males, 5 females, age range: 7 - 12 months, mean age: 9.25 +/- 1.70 months) with negative MRI findings. And another 12 age-matched and gender-matched infants were enrolled as control subjects. Fractional anisotropy (FA) of different white matter tracts of the brain was measured in both groups.

RESULTSFor patients with negative MRI findings, compared with healthy infants, a statistically significant reduction in DTI FA value of the frontal white matter, temporal white matter, and occipital white matter was observed (P < 0.01).

CONCLUSIONSIn addition to conventional T1W and T2W MR Image, Brain DTI presents a useful, sensitive and complementary tool for the assessment of brain damage in patients with MMA.
