BACKGROUND: In the ischemic cerebral area there are viable tissues of low blood perfusion. Theses tissues can be rescued as long as blood supply is restored timely. As an imaging agent,99Tcm-HL91 can be used to demonstrate the viable cerebral tissues in hypoxic and ischemic area.OBJECTIVE: To investigate the value of 99Tcm-HL91 imaging in assessing ischemic stroke,in order to provide evidences for early intervention.DESIGN: An observational and controlled trial based on patients and healthy voluinteers.SETTING: A nuclear medicine department in a university and a neurological department and a nuclear medicine department in a provincial hospital.PARTICIPANTS: From March 2000 to September 2001,eighteen inpatients and outpatients suffering from ischemic cerebral diseases and 4 volunteers were enrolled in the study.METHODS: In the 18 patients,11 were clinically diagnosed as cerebral infarction,5 TIA,2 vertebrobasilar insufficiency. All the subjects underwent 99Tcm-HL91 cerebral hypoxia tomographic imaging. The labeled 99Tcm-HL91(555-1 110 MBq) was intravenously injected into the human body and imaging was conducted after 20 -30 minutes,17 patients underwent CT or MRI examination at the same time. Eleven patients underwent 99Tcm-ECD tomopraphic imaging on the next day. The results of the 3 examinations were compared with each other. The uptake in the inside and around-infarct areas was determined by direct visual observation on the images. Positive change was given by presence of increased uptake and negative by absence. The uptake change that could not be clearly defined as positive or negative was considered critical level. But the uptake on both hemispheres was compared with ROI technology. The change over 25% between hemispheres was set as positive and the other was negative. So there was no critical group in this study.MAIN OUTCOME MEASURES: The results of cerebral hypoxia imaging,CT,MRI and cerebral perfusion imaging.RESULTS: Among the 18 patients,5 were positive for hypoxia imaging(4infarction and 1 vertebrobasilar insufficiency). In the 99Tcm-ECD perfusion,6out of 11 patients manifested of regional decreased blood perfusion. Nine patients manifested of abnormal CT or MRI results. No abnormalities were detected in the 4 volunteers.CONCLUSION: Although 99Tcm-HL91 imaging for diagnosis of cerebral ischemic disease is affected by many factors,it can identify whether the ischemic tissue is hypoxic or necrotic when the perfusion imaging demonstrate low flow. So it helps in guiding rehabilitation intervention and foretelling prognosis.

Objective To explore the sensitivity of contrast-enhanced ultrasound (CEUS) and ultrasonic elastography(UE) in detecting different sizes of thyroid papillary carcinoma.Methods 64 cases of thyroid papillary carcinoma were divided into two groups according to the diameter size(group 1,≤1 cm;group 2,＞ 1 cm) and examined by the contrast-enhanced ultrasound and elastography,then the features were analyzed and the sensitivity for detecting of the two methods in different groups were compared.Results The sensitivity for detecting in CEUS was higher than in UE,which had significant difference between two methods.CEUS and UE were valuable for detecting and they had no difference in sensitivity for detecting in group 1.There was a significant difference in sensitivity for detecting between two methods in group 2.Conclusions Both CEUS and UE were valuable in diagnosis of thyroid papillary carcinoma and the sensitivity for detecting in CEUS is higher than in UE in group 2.

Objective Pathogen and antimicrobial susceptibility in children with bacterial meningitis were reviewed.Methods The positive cultures of cerebrospinal fluid samples or blood samples and its antimicrobial susceptibility were analyzed in 401 patients with the clinical diagnosis of bacterial meningitis.Results 401 cases cerebrospinal fluid samples and blood samples submitted to microbiology laboratory, 97 cases (24%) were microscopically and culturally proven to be bacterial meningitis. The most frequent pathogen was staphylococcus aureus (28%), followed by the streptococcus pneumoniae (19%) and escherichia coli (13%). Pediococci as conditioned pathogen, were found in purulent meningitis patients. One of the isolates of Staphylococcus aureus was simultaneously resistant to both vancomycin and teicoplanin. Three isolates showed simultaneous resistance to imipenem/cilastatin.Conclusions Staphylococcus aureus as the predominant pathogens of pediatric ranks first among pediatric patients of purulent meningitis. Serious drug resistance of isolated pathogenic bacteria and its in antimicrobial susceptibility in the bacterial meningitis should be considered in clinical therapy.

Objective To investigate the diagnostic efficiency of 64-slice CT coronary angiography (CTCA) to myocardial ischemia of coronary stenosis. Methods ~(99m) Tc-MIBI myocardial perfusion imaging (MPI) and 64-slice CTCA were performed in 30 patients with myocardial ischemia of coronary stenosis. Three coronary arteries were divided in to 12 segments in each patient, the diagnostic efficiency of CTCA to myocardial ischemia of coronary stenosis were eveluated taking MPI as diagnostic standard, and stenoses ≥50% and ≥75% as the cutoff value. Results In 9 patients, perfusion defected were found (6 reversible, 3 fixed) on MPI. A total of 327 coronary arteries' segments were analyzed, quantitative CTCA revealed stenoses ≥50% in 25 segments (7.65%) and stenoses ≥75% in 12 segments (3.67%). When the cut-off was ≥50%, the sensitivity, specificity, negative and positive predictive value (NPV, PPV) and accuracy of CTCA by the abnormal images of MPI as diagnostic standard to observe abnormal arteries was 68.42%, 96.14%, 99.01%, 52.00% and 95.41%, respectively; and 66.67%, 99.04%, 98.73%, 66.67% and 97.55%, respectively, when cut-off at ≥75%. Taking abnormal MPI as diagnostic standard to observe the patients, the sensitivity, specificity, NPV, PPV and accuracy of CTCA was 66.67%, 57.14%, 80.00%, 40.00% and 60.00% respectively, with the cut-off at ≥50%; and was 55.56%, 85.71%, 81.82%, 62.50% and 76.67%, respectively, with the cut-off at ≥75%.Conclusion Sixty-four-slice CTCA is a reliable tool to rule out functionally relevant myocardial ischemia of coronary artery disease. However, further examination is necessory for patients with abnormal CTCA.

Objective:To observe the clinical efficacy of Yi Jin Jing (Sinew-transforming Qigong Exercises) for primary osteoporosis in the elderly.Methods:Eighty old patients with primary osteoporosis were randomized into a Yi Jin Jing group and a medication group,40 cases in each group.The Yi Jin Jing group was intervened by Yi Jin Jing (Sinew-transforming Qigong Exercises) training,while the medication group was intervened by oral administration of alendronate sodium tablet.Prior to and after 6-month intervention,the bone mineral density (BMD) of the proximal femur,visual analog scale (VAS) and activities of daily living (ADL) were estimated.Results:There were no significant differences in the BMD of the proximal femur,and VAS and ADL scores between the two groups before the intervention (P＞0.05).After 6-month intervention,the above items all improved significantly in both groups (both P＜0.01);the improvements in VAS and ADL scores in Yi Jin Jing group were more significant than those in the medication group (P＜0.01),while the between-group difference in the BMD of the proximal femur was statistically insignificant (P＞0.05).Conclusion:Practice of Yi Jin Jing (Sinew-transforming Qigong Exercises) can effectively ameliorate the BMD in the elderly with primary osteoporosis,and it can reduce the pain and improve ADL,with a better general effect compared to oral administration of alendronate sodium tablet.

OBJECTIVETo investigate the effect of embryonic dermal signal on the hair-inductive capacity of neonatal mice dermal cells which have been amplified in vitro.

METHODSEmbryonic mice dermal cells of embryonic day 14 were added to a chamber on the back of nude mice with neonatal mice dermal cells which had been amplified in vitro for 3 days and freshly isolated neonatal mice epidermal cells. The hair regeneration was compared between the groups with or without embryonic mice dermal cells. Meanwhile, chambers with following cells respectively were constructed as controls: embryonic mice dermal cells + neonatal mice epidermal cells; freshly isolated neonatal mice dermal cells + neonatal mice epidermal cells; amplified neonatal mice dermal cells only; embryonic mice dermal cells only; freshly isolated neonatal mice dermal cells only; neonatal mice epidermal cells only.

RESULTSThe number of regenerated hairs with the aid of embryonic mice dermal cells (207 +/- 15. 948) was significantly higher than that (67 +/- 8.963) in the group without embryonic mice dermal cells (n = 3, t = 7.653, P = 0.002).

CONCLUSIONEmbryonic dermal signal can enhance the hair-inductive capacity of neonatal mice dermal cells which have been amplified in vitro.
