OBJECTIVETo study clinical effects of inversive LISS (less invasive stabilization system, LISS) plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures.

METHODSFrom January 2009 to Janurary 2012, 11 patients with Seinsheimer type V subtrochanteric femoral fractures were treated with inversive LISS plate combined with steel wire, including 8 males and 3 females, ranging in age from 35 to 61 years old (averaged, 51 years old). Causes of injury: 8 patients caused by accident and 3 patients caused by falling down. According to X-ray examination, all the patients were type V subtrochanteric femoral fractures and were treated with LISS plate combined with steel wire. Merle d'Aubigne scores were used to evaluate therapeutic effects on hip.

RESULTSThe mean period of follow-up was 16 months (ranged, 12 to 28 months). All the patients obtained bone union for average 3.8 months (ranged from 3 to 4.3 months). There were no complications such as deep infection,deep vein thrombosis, pulmonary embolism and bone nonunion. According to Merle d'Aubigne scores, 7 patients got an excellent result and 4 good.

CONCLUSIONInversive LISS plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures is satisfactory, Which can provide stable fixation for fracture end and provide an ideal internal fixation method for treatment of this kind of fractures in the future.

The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

BACKGROUND: The degree of neurofilament (NF) phosphorylation is closely correlated with the occurrence of Alzheimer disease (AD), and apolipoprotein E4 (apoE4) is a generally acknowledged liability factor for AD, but the effect and mechanism of apoE4 on the NF phosphorylation in neurons are not very clear. It has been reported that in the neurons cultured in vitro and in brain tissue of AD patients, the amino acid residues of apoE4 protein C terminal (272-299) could be truncated by hydrolysis,and produce truncated-apoE4 fragment. The latter interacts with the NF phosphorylation in neurofibrillary tangles (NFTs), which are the characteristic pathological changes of AD.OBJECTIVE: To observe the effect of truncated-apoE4 overexpression on the NF phosphorylation in the cultured neurons.DESIGN: A non-randomized controlled observation.SETTING: Department of Biochemistry and Molecular Biology, School of Basic Medical Sciences, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was carried out in the Laboratory of Biochemistry and Molecular Biology, Tongji Medical College, Huazhong University of Science and Technology in December 2005. The mice neuroma cell strain N2a was provided by Dr. Xu.METHODS: The truncated-apoE4(△272-299) cDNA was subcloned into pEGFP-c3 to form pEGFP-T-apoE4 recombinant. Then pEGFP-c3, pEGFP-apoE4 and pEGFP-T-apoE4 were transfected into N2a cells by lipofectamine2000 respectively. NF phosphorylation was detected by Western blot assay. The activities of glycogen synthase kinase-3 (GSK-3) and cyclin-dependent kinase 5(CDK-5) were measured.MAIN OUTCOME MEASURES: The degree of NF phosphorylation and the activities of GSK-3 and CDK-5 were mainly observed.RESULTS: In the transfected groups, the contents of phosphorylated NF were significantly increased, the GSK-3 activities were significantly increased, which were the most significant in the pEGFP-T-apoE4 transfected group (P＜0.05), but the CDK-5 activities were not significantly different from that in th e control group (P＞0.05).CONCLUSION: These results indicate that in vitro overexpression of truncated-apoE4(△272-299) can lead to NF hyperphosphorylation by activating of GSK-3 but not CDK-5, which may be the underline mechanism of AD induced by truncated-apoE4(△272-299).

Objective To find out and clarify the causes and the pathogens of vulvovagmitis in childhood girls, to determine the clinical treatment. Methods There were 345 cases of childhood girls .ranged from 18 days to 12 years, with symptoms of vulvovagini tis, and their vaginal secretions were examined by routine smear for cleaning degree, trichomonas , Candida and clue cells, gram-stain for neisseria gonorrhoeae, culture for bacteria, mycoplasma urealytium, mycoplasma hominis and chlamydia trachomatis. Results One hundred and nine pathogens were detected(31.6% of the whole cases ), including specific pathogen 70 cases(20. 3% )and non-specif ic pathogen 32 cases(9.3%). Gardnerella was detected most frequently in specific pathogen while enteric bacilli was detected most frequently in non-specific pathogen. Conclusions Non-specific vulvovaginitis is the most frequent cause in childhood vulvovagimtis, and bacterial vaginosis is the mast frequent in specific infection. Symptomatic treatment is effective, but antibiotic treatment should be based on pathogenic findings of vaginal secretions.
