ABSTRACT
Objective To explore the dynamic characteristics of the thoracolumbar osteoporotic vertebral bodies under free state. Methods Based on CT data from the thoracic and lumbar vertebral body of a healthy female volunteer, model materialization and intervertebral disc tissue reconstruction were realized by using the computerized processing software. The finite element models of normal thoracolumbar vertebral body and thoracolumbar osteoporotic vertebral body were established in ABAQUS 6.14 to perform modal analysis. Results Compared with the normal model, the osteoporosis model had a lower natural frequency and a lager amplitude. As the vibration frequency increased, the model vibration type changed from uniaxial and unidirectional motion to multiaxial and multidirectional motion, and the responsible vertebral body for the maximum amplitude moved down gradually. Conclusions Modal analysis can better analyze dynamic characteristics of the thoracolumbar osteoporotic vertebral body. Patients with osteoporosis should try to avoid the specific vibration environment, so as to decrease the risk of intervertebral disc tissue degeneration, strain of thoracolumbar soft tissues and lesion in posterior structures of the vertebral body.
ABSTRACT
Objective To discuss the disposition feature of pathogenic bacterium in female urinary tract infection(UTI) ,so as to elevate the level of clinical diagnosis and therapy. Methods To cultivate medistream urine,assess vaginal secretions in the aspects of bacteriology, mycoplasma, chlamydia, mycetes and parasite. All specimen collected from 129 female patients who chiefly complained irritation of urinary tract ,from January 2003 to December 2006. Results Pathogenic microorganisms that found in the 129 female patients with UTI are gram-negative bacteria( 53.49 % ), gram- positive bacteria ( 19.38 % ), mycoplasma ( 14.73 % ), mycetes (9.30 % ), chlamydia (4.65 % ),parasite(1.55% ). Among them, escherichia coli, klebsiella pneumoniae bacilli, enterococcus faecalis, staphylococcus aureus are common species. Sexually transmitted disease(27.91% ) include the infection of diplococcus gonorrhoeae,mycoplasma and ehoamydiae. Among them,non-gonococcal urethritis is common. Combined infection(17.38 % ). Infection combined with mycoplasma urealytium and other pathogen is the most, these patients are most young or middle aged. Conclusion Pathogen in female UTI is mostly gram-positive bacteria. STD and combined infection should be paid attention to by clinicians. We suggest female UTI patients take etiological test regularly,so as to elevate the level of clinical diagnosis and therapy.
ABSTRACT
OBJECTIVE:To observe the protection and delaying effects of rosiglitazone on the onset and progression of type2diabetic nephropathy of senile patients.METHODS:23senile patients with type2diabetic nephropathy were random-ized to A and B groups.Group A were treated with rosiglitazone4mg/d and group B were administered orally with dimethyl biguanide1750mg/d(in3times),the course of treatment for both groups were4months.RESULTS:The post-meal blood sugar in both groups showed significant differences after treatment as against pretherapy(P0.05).CONCLUSON:Rosiglitazone has significant curative effect on diabetes,it can also delay the occurrence of albu-minuria and significantly lighten pathological changes of renal glomerulus.
ABSTRACT
OBJECTIVE: To observe the renal protective effects of ramipril and atorvastatin used in combination or alone for diabetic nephropathy. METHODS: 54 patients were randomly assigned to receive ramipril 5 mg q.d (Group A), atorvastatin 10 mg q.d (Group B) or ramipri 5mg qd + atorvastatin 10mg q.d (Group C) for 18wk. RESULTS: After 18-week treatment, levels of both urine protein and blood lipid decreased in all the three groups (P0.05). CONCLUSION: Either Ramipril or Atorvastatin alone had satisfactory effect on diabetic neph-ropathy, but a more remarkable protection effect on kidney was noted when they used in combination.
