BACKGROUND:There have been many studies on the diagnosis of osteoporotic vertebral compression fractures. However, there are few studies on the diagnostic methods of fracture in different periods. OBJECTIVE:To comparatively analyze the application value of high-intensity magnetic resonance imaging (MRI) and single photon emission computed tomography combined with CT scan image fusion (SPECT-CT) in the diagnosis of osteoporotic vertebral compression fractures. METHODS:Clinical data of 35 patients with osteoporotic vertebral compression fractures were retrospectively analyzed, including 56 vertebrae. There were 14 males and 21 females, with an average age of 72.6 years. The course of disease was within 3 weeks in 22 patients, belonging to acute fractures. The course of the disease was between 4 and 12 weeks in 10 patients, belonging to the subacute fractures. The course of disease was 6 months in 3 patients, belonging to the fracture healing period. Al patients were tested with high-intensity MRI and SPECT-CT examination, and were treated with vertebroplasty or percutaneous kyphoplasty. The Fisher exact method was used to compare the two diagnostic methods in the diagnosis of vertebral fracture. RESULTS AND CONCLUSION:(1) In the 56 responsible vertebral bodies, 32 vertebral bodies belonged to the acute-stage fractures, and 24 vertebral bodies belonged to the non-acute-stage fractures. In al the fractures, MRI diagnosed 49 segments;SPECT-CT diagnosed 52 segments. The sensitivity of SPECT-CT testing was higher than MRI, and its specificity was less than MRI. There was a high consistency of diagnosis between fractures. (2) In the 32 acute vertebral fractures, the two tests diagnosed 29 segments. The sensitivity of SPECT-CT was higher than that of MRI, but its specificity was lower than that of the MRI. There was a high consistency between the diagnoses of fractures. (3) In the 24 non-acute vertebral fractures, MRI diagnosed 20 segments;SPECT-CT diagnosed 23 segments. SPECT-CT was more sensitive than MRI;the specificity of SPECT-CT was lower than MRI. There was a high consistency between the two diagnoses of fractures. (4) There was a high consistency in the MRI and SPECT-CT examination to determine the fracture of different periods of responsibility of the vertebral body, but the sensitivity of SPECT-CT is higher than MRI examination;SPECT-CT is an effective inspection method in the diagnosis of vertebral fractures.

Objective To evaluate the effects of traditional Chinese medicine likeDansen and western medicine in treating traumatic brain edema (TBE). Methods A total of 130 Wistar rats were divided randomly into six groups: Group A (normal contrast group), Group B (operation group), Group C (western medicine treatment group, WM group), Group D (western medicine and salvia injection), Group E (western medicine and Honghua injection) and Group F (western medicine and Sanqi injection). The model of brain edema was established by liquid nitrogen treatment to assay whole blood viscosity, water content and Even blues (EB) in brain tissues and to observe the content and pathologic changes of endothlin (ET) in plasma. Results Whole blood viscosity of Groups D, E and F was lower than that of Group B (P0.05). Water content and EB in brain tissues and ET of plasma in Groups C, D, E and F were lower significantly than those in Group B (P

[Objective]In present study an in vivo wear particles induced mouse calvarial osteolysis model was used to investigate the inhibitory effect of erythromycin over wear particles induced osteolysis.[Method]Twenty-four male eight-week-old C57BL/J6 mice were allocated into 4 groups: PMMA group receiving 30 mg PMMA particles implantation onto the calvariae,PMMA+2EM group receiving 30 mg PMMA particles implantation and EM 2mg/kg ip injection,PMMA+10EM group receiving 30 mg PMMA particles implantation and EM 10mg/kg ip injection,control group receiving sham operation.Seven days later,mice calvariae were harvested for pathology analysis.[Result]Middle suture area in the control group was 0.079 mm2?0.011 mm2,in PMMA group 0.335 mm2?0.129 mm2.In PMMA+2EM group the area was 0.094 mm2?0.019 mm2,PMMA+10EM group was 0.091 mm2?0.028 mm2.Osteoclasts number in osteolysis area in the control group were 5.3?1.0,in PMMA group 19.2?5.3,PMMA+2EM group was 6.6?1.1,PMMA+10EM group 6.1?1.9.Compared with control group,PMMA particles induced significant osteolysis(P

Objective To evaluate the efficacy and safety of ultrasound-guided percutaneous ethanol injection(PEI)in the treatment of solitary benign thyroid adenoma.Methods One hundred and twelve patients with thyroid adenoma underwent PEI.The amount of anhydrous ethanol injected was approximately one third of the volume of thyroid nodule and used once a week,the injection was repeated two to five times.Results The average volume of pure adenoma and adenoma associated with cystic degeneration is ( 4.93 ? 0.48 )cm 3 and ( 7.89 ? 0.91 )cm 3;the nodules decreased markedly to ( 3.22 ? 0.40 )cm 3 and ( 3.85 ? 0.55 )cm 3 3 months after PEI treatment (P

Objective To investigate the correlation of the expressions of PTTG and VEGF proteins in extrahepatic cholangiocarcinoma,and study its role in the development of extrahepatic cholangiocarcinoma.Methods Expression of PTTG and VEGF proteins was detected by SABC immunohistochemical technique in 36 cases of extrahepatic cholangiocarcinoma,30 cases of adjacent histologically noncancerous bile duct tissues and 12 cases of benign bile duct lesions.Results The positive rates of PTTG and VEGF proteins were(72.2)%(26/36) and 83.3%(30/36) respectively,in extrahepatic cholangiocarcinoma;and 63.3%(19/30) and 76.7%(23/30) in adjacent histologically noncancerous bile duct tissues.The expression of PTTG protein was significantly positively correlated with that of VEGF protein(P

OBJECTIVETo compare the difference in the clinical efficacy on post-stroke insomnia between the low-frequency electric stimulation at the acupoints and the conventional western medication.

METHODSOne hundred and twenty patients of post-stroke insomnia were randomized into a low-frequency electric stimulation group, a medication group and a placebo group, 40 cases in each one. In the low-frequency electric stimulation group, the low-frequency electric-pulsing apparatus was used at Dazhui (GV 14) and Shenshu (BL 23), once a day; the treatment of 15 days made one session and 2 sessions were required. In the medication group, estazolam was taken orally, 1 mg each time. In the placebo group, starch capsules were taken orally, 1 capsule each time. All the drugs were taken before sleep every night, continuously for 15 days as one session, and 2 sessions were required. PSQI changes and clinical efficacy were observed before and after treatment in each group.

RESULTSPitlsburgh sleep quality index (PSQI) score was reduced in every group after treatment (all P < 0.01). In the low-frequency electric stimulation group and medication group, the score was reduced much more significantly as compared with the placebo group (both P < 0.01). In the placebo group, 1 case was rejected. The total effective rates were 95.0% (38/40), 92.5% (37/40) and 17.9% (7/39) in the low-frequency electric stimulation group, medication group and placebo group separately. The efficacy in the low-frequency electric stimulation group and medication group was better apparently than that in the placebo group (both P < 0.01).

CONCLUSIONThe low-frequency electric stimulation at the acupoints effectively and safely treats post-stroke insomnia and the efficacy of it is similar to that of estazolam.
