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.

Objcetives To sparch for the change of cerebrospinal fluid ferritin (CSF-Ft) content and its clinical significance.Methods The 42 patients with acute lymphatic leukemia(ALL)diagnosed by bone marrow biopsy were divided into 3 groups. There were 14 cases in Ⅰ group [introduced therapy stage without central nervous system leukemia(CNSL)7, 24 cases in Ⅱgroup (complete remission stage without CNSL) and 18 cases in Ⅲ grotip (with CNSL). There were 17 patients with viral encephalitis in viral encephalitis group and 15 patients without central nervous system oisease in control group. The CSF-Ft and SFt were determined by radioimmunoassay.Results The CSF-Ft contents of Ⅰ、Ⅱ、Ⅲ 、viral encepbalitis and control groups are 7.03 ?2.21 ?g/L,6.75 ?1.94?g/L, 31.06 ? 8.85?g/L, 7.26?1.83?g/L and 6.52 ?1.57?g/L. The CSF-Ft content in Ⅲ group are bigher than that in the other group (P

AIM AND METHODSIn the present study, we investigated the TH immunoreactivity and the expression of angiotensin AT1 receptor in locus coeruleus after intracerebroventricular (i. c. v.) injection of carbachol in conscious SD rats with immunohistochemistry. Meanwhile the effects of blocking AT1 receptor were also observed.

RESULTSBoth mean optical density and number of TH and AT1 immunoreactive positive neurons were markedly increased in locus coeruleus after 40 minutes of i.c.v. injection of carbachol (0.5 microg). The enhancement was significantly reduced by i. c. v. injection of losartan.

CONCLUSIONThe results above suggest that i. c. v. injection of cholinergic agonist carbachol can enhance the activity of adrenergic neurons and the expression of AT1 receptor in locus coeruleus. The blockade of AT1 receptor may down regulate the above action induced by carbachol in locus coeruleus.

Objective: To identify the functional domain of ?-Synuclein in affecting mitochondrial function and how the function to be impaired,especially,the mitochondrial membrane potential and the release of Cytochrome c.Methods: Harvest of ?-Syn-N and ?-Syn-△N by PCR,then subcloned into the pCMV-Myc mammalian expression vector.The recombinant plasmids were transfected into HEK293T cells by Lipofectamine 2000.After detecting the protein expression by Western blot,the functional domain was detected by co-immunoprecipitation.The mitochondrial membrane potential through flow cytometry and immunofluorescence,at the same time,the release of Cytochrome c through flow cytometry to detect.Results: The recombinant plasmids were constructed successfully.CO-IP has proved that N-terminal may be the functional domain of ?-Synuclein in affecting mitochondria.Over-expression of N-terminal could depolarize the mitochondrial membrane potential and induce the Cytochrome c releasing in MN9D cells.Conclusion: N-terminal may be the functional domain of ?-synuclein and over-expression of N-terminal could decrease mitochondrial activity.

Objective To investigate the prevalence of low T3 syndrome in patients with acute myocardial infarction(AMI) and explore the effect of low T3 syndrome on outcome of AMI.MethodsThree hundred and thirty-eight patients with AMI admitted to cardiac care unit(CCU) underwent examinations of thyroid function and cardial ultrasound,and were further categorized according to thyroid hormone profile.The records of noninvasive bi-level positive airway pressure(BiPAP)ventilation utilization,length of hospital stay,mortality during hospitalization were evaluated,and the related factors were analysed.ResultsOne hundred and thirty-nine of the 338 patients(41.12%) with AMI complicated with low T3 syndrome.Free triiodothyronine(FT3) was the independent influential factor for length of hospital stay.Low FT3 was significantly correlated with noninvasive BiPAP ventilation utilization and mortality during hospitalization.The average time of follow-up was(21.4?8.1) months.It was revealed by multivariate Cox regression analysis that FT3 was the chief predictor for cumulative death(risk ratio,4.25;95% confidential interval,2.30-7.87),followed by age and left ventricular ejection fraction.ConclusionThe recognition of AMI complicated with low T3 syndrome plays an important role in predicting the disease severity and outcome.

AIM: To compare the effectiveness of botulinus toxin of type A and complete resection of the periorbital muscle on idiopathic blepharospasm.
● METHODS: Patients with idiopathic blepharospasm and having undergone either of two procedures from Dec. 2010 to Jun. 2015 were selected ( 60 patients ) . Among them, group A (30 patients, 60 eyes) underwent botulinus toxin of type A, group B (30 patients, 60 eyes) underwent complete resection of the periorbital muscle.
●RESULTS: ln group A, the patients with complete response, obvious response, partial response, and no response were 36(60. 0%), 20(33. 3%), 2(3. 3%) and 2 (3. 3%) cases respectively. ln group B, the patients with complete response, obvious response, partial response, and no response were 16(26. 7%), 24(40. 0), 12(20. 0%) and 8 ( 13. 3%) cases respectively. The difference was statistically significant ( Z = - 2. 968, P = 0. 003 ). The relapse rate of group A and group B were 93. 3% and 20. 0% after 6mo, the difference was statistically significant (χ2=32. 851, P<0. 001).
●CONCLUSION: The botulinus toxin injection of type A is effective for idiopathic blepharospasm. But recurrence rate is high after 6mo. Complete resection of the periorbital muscle have long-term efficacy for idiopathic blepharospasm. It′s a supplementary therapy after idiopathic blepharospasm recurrence.

Objective To explore the effect of chromosomal abnormality and polygenic inheritance factor in female children with short stature.Methods 1.Chromosome analysis:peripheral blood was drawn for 1 mL and cultured 72 h to analyze chromosome karyotype (Giemsa Banding ) of peripheral lymphocytes.2.Polygenic factor analysis:the children′s final height were estimated based on their parents average height,and analyzed the distribution characteristics of children′s final height and compared the estimate final height with the actual height.Results Eighty-three cases out of the 364 female children with short stature were chromosomal abnormality(22.80%).Among the 83 cases,the 45,XO and 46,X,i(Xq) occupied 70%.The distribution of children target height shifted left,and the target height of 76 cases was lower than 2 standard deviation (-2 s)and the consistency of target height and actual height reached 20.88%.The target height of 7 cases was lower than 2 standard deviation in those whose chromosome turned out to be abnormal,and the consistency of target height and actual height was 8.43%.Conclusions Chromosomal abnormality is one of the most important etiologic agents causing short stature in female children, and polygenic inheritance is another important etiologic agent.

Objective To explore the feasibility of bilingual teaching in the course of Physical Therapy, and find out the more suitable program of the bilingual teaching for undergraduate students of rehabilitation therapy. Methods Students of rehabilitation therapy from Capital Medical University School of Rehabilitation Medicine were randomly divided into two groups: experimental group received bilingual education during the teaching session, while the students in control group received traditional teaching method. Their scores of the quiz were compared, and the students were investigated with the questionnaire.
