Establishment of rabbit subarachnoid hemorrhage model and the imaging findings of a little amount of subarachnoid hemorrhage in acute phase / 实用放射学杂志

Objective To explore the sensitivity of a little amount of subarachnoid hemorrhage (SAH) between CT and different MR sequences through animal experiment,to find a more sensitive way to diagnosis SAH.Methods 18 healthy adult white New Zealand rabbits were randomly divided into two experimental groups(group A and group B) and one control group(group C).Rabbit SAH model was established by injecting blood into the cisterna magna one time.All rabbits underwent CT and MR scan at 2 hours,48 hours after operation.The findings on CT and different MR sequences were observed and recorded.Results ①In experimental groups(group A and group B),MR FLAIR sequences in the diagnosis of a little amount of SAH was more sensitive than that on MR T1WI,T2WI and CT in acute phase.And the diagnosis sensitivity between MR FLAIR and CT was statistically significant(P<0.05).②Abnormal signs of SAH could not be found in group C.Conclusion ①Rabbit SAH model was established successfully which will be the foundation for the follow-up study of medical imaging.②MR FLAIR sequence is more sensitive to diagnose a little amount of SAH in acute phase,and may be used in the routine diagnosis of SAH in acute phase.

MRI analysis of tumor-like inflammatory demyelinating diseases / 实用放射学杂志

Objective To analyse and summarize the MRI characteristics of tumor‐like inflammatory demyelinating diseases (TIDD) .Methods MRI findings of 10 cases with pathologically proved TIDD were analyzed retrospectively ,all patients received plain and enhanced MRI scan .Results 3 cases showed multiple lesions in bilateral frontal and parietal lobes ,and 7 cases showed soli‐tary mass ,in which 2 lesions located in the occipital lobe ,2 in the basal ganglia ,2 in the second to fifth segment of cervical cord ,and 1 lesion located in the left frontal parietal lobe .The shape of 7 lesions were irregular ,2 were stripped ,while 1 lesion was oval .6 cases had clear boundary ,while 4 showed ambiguous .Solitary lesions were 1 .7 cm -5 .6 cm in diameter(mean 4 .0 cm ± 1 .48 cm) .8 cases manifested mild edema while 2 had no edema .On MRI plain scan ,lesions were hypointensity on T1WI and hyperintensity on T2WI in 8 cases ,isointensity on T1 WI and hyperintensity on T2 WI in 2 cases ,and all lesions were hyperintensity on FLAIR sequence .DWI were performed in 3 cases ,all lesions showed hyperintensity ,2 of them had patchy hypointensity signal .Hemorrhage was detected in 3 lesions ,cystic lesions or calcification were not found in all cases .On post‐contrast scan ,3 lesions showed ring like enhancement ,2 showed obviously heterogeneous enhancement ,2 had mild enhancement and 2 cases had no enhancement ,1 presented with open ring like enhancement .Conclusion TIDD shows some specific MRI features ,and MRI is helpful to the diagnosis of TIDD .

Therapeutic Observation of Acupoint Thread Embedding plus Ultrashort Waves for Sleep Disorders Due to Restless Legs Syndrome / 上海针灸杂志

Objective To observe the clinical efficacy of acupoint thread embedding plus ultrashort waves in treating sleep disorders due to restless legs syndrome (RLS).Method Forty-eight RLS patients were randomized into a treatment group and a control group, 24 cases in each group. The treatment group was intervened by acupoint thread embedding plus ultrashort waves, while the control group was by orally taking Levodopa and Benserazide Hydrochloride tablets and Compound Vitamin B tablets. The Pittsburgh Sleep Quality Index (PSQI) was observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The PSQI scores were significantly changed both after 2 and 4 weeks of treatment in both groups (P<0.01). PSQI scores in the treatment group respectively after 2 and 4 weeks of treatment were significantly different from that in the control group (P<0.01). The total effective rate was 100.0% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Acupoint thread embedding plus ultrashort waves is an effective method in treating sleep disorders due to RLS.

Clinical Observation of Acupuncture Therapy for Postherpetic Neuralgia / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of acupuncture therapy for postherpetic neuralgia in the elders. Methods: Twenty-four cases of postherpetic neuralgia were randomized into two groups, an acupuncture group in which 12 cases were treated by acupuncture at Jiaji (Ex-B 2) on the diseased side, and a medication group in which 12 cases were treated by oral obtundent and intramuscular injection of neurotrophic drugs. Results: After four-week treatments, the total effective rate was 91.6% in the acupuncture group and 83.3% in the medication group. Conclusion: Acupuncture can significantly relieve postherpetic neuralgia, with better effects than medication.
