Methods of ELISA, nonradioactive molecular hybridiz ation and RT-PCR were applied in the detection of rice grassy stunt virus (RGSV ). The detection sensitivity of indirect ELISA using antiserum against fusion p rotein GST-NC was 1 mg of infected leaves or 84 ng of purified virus. The metho d of dot hybridization using NC, a DIG-labelled DNA probe was 50 μg diseased l e aves, or 6 ng purified preparations. The detection endpoint of RT-PCR was 10 μg diseased leaves, or 2 ng purified virus preparation. Comparisons of sensitivit y and maneuverability were made among these methods.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P＜O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.

Objective: To observe the therapeutic efficacy of music electric stimulation of points in treating anxiety. Methods: By adopting a design of multi-centered randomized controlled trial (RCT), a total of 270 patients with anxiety were randomized into a treatment group and a medication group. The treatment group was intervened by music electric stimulation of points, while the medication group was intervened by oral administration of doxepin. The two groups were evaluated by using Hamilton anxiety rating scale (HAMA) and Chinese revised edition of self-rating anxiety scale (SAS-CR) before and after the intervention. The therapeutic efficacies were also compared. Results: The total effective rate was 93.6% in the treatment group versus 92.3% in the medication group, and the between-group difference was statistically insignificant (P>0.05). After the treatment, the aggregate scores of HAMA and SAS-CR were significantly changed in both groups (both P<0.001), and the inter-group differences were statistically insignificant (P>0.05). Conclusion: Music electric stimulation of points can produce equivalent efficacy in treating anxiety compared to doxepin. Thus, it can be taken as a choice in the treatment of anxiety.

Objective To observe the effects of a motor relearning programme (MRP) combined with different early acupuncture interventions on muscle tension and motor function recovery after cerebral infarction.MethodsA total of 90 patients with cerebral infarction who met the inclusion criteria were divided into three groups at random:a YANGMING meridian acupuncture and MRP group ( group A),an anti-spasm acupuncture and MRP group ( group B),and an MRP group ( group C ).All of the patients in all three groups were treated with routine medication.The National Institute of Health stroke scale (NIHSS),the composite spasticity scale (CSS),Fugl-Meyer assessment (FMA),the Fugl-Meyer balance scale (FM-B) and the modified Barthel index (MBI) were used to measure performance before treatment and after 4 weeks of treatment.Another comparison was intra-group between before and after treatment. ResultsThere were significant differences in the assessment results in all of the groups after treatment compared with those before treatment.After treatment,group B was superior to group C only in terms of NIHSS scores.There was no significant NIHSS score difference between groups A and C.The FMA,CSS and MBI results revealed significant differences among all three groups,with the scores of group A consistently the highest.The average FMA score in group B was significantly higher than in group C but there was no statistically significant difference in FM-B scores among the three groups. ConclusionMRP therapy combined with early acupuncture intervention can improve motor function and muscular tension after cerebral infarction.Anti-spasm acupuncture can improve motor function and control muscular tension effectively at the same time,making it beneficial for MRP training.
