Objective To investigate the correlation between level of Titin antibodies (Titin-Ab) and patient's condition and different thymic pathological patterns in patients with myasthenia gravis (MG), and to assess its value in the diagnosis and prognosis of MG.Methods The levels of Titin-Ab in serum from 52 patients with MG (MG group), 18 cases with other neurologic diseases (NMG group) and 50 normal controls (NC group) were detected using enzyme-linked immunosorbentassay (ELISA). 10 cases with MG who received operation on thymus were tested again after therapy.Results The positive rate of Titin-Ab in MG group was 36.5%,but not present in MNG and NC groups.The MG group!was significantly higher than those in NMG group and NC group (all P

Objective To introduce a simple and reliable way for atrial septal puncture. Methods Atrial septal puncture had been carried out in 627 patients with various underlying heart diseases, and the patients aged between 4-78 years old. Three protocols for precise location of atrial septal puncture points were recommended, 1) Site of atrial septal puncture point in cranial-caudal direction was determined under posterior-anterior projection, which was confined to the cranial side of the inferior margin of left atrium silhouette at a distance of 1 cone body height along the midline of spine. If the inferior margin of left atrium silhouette was unclear, angiogram of pulmonary artery to display left atrium and placement of coronary sinus electrodes could be done to verify it. 2) Under right anterior oblique 45 degree view, the puncture point was located between one cone body height anterior to posterior margin of left atrium silhouette and the isometric line between the posterior margin of left atrium silhouette and atria-ventricular suculus. 3) The arch feature of puncture needle and distal part of sheath turned into a straight line under 45 degree of right anterior oblique view. Results The success rate of atrial septal puncture was 99.8% (626/627), and that with only one try was 71.93% (451/627), the rate of tamponade was 0.32% (2/627). No death occurred. Conclusion Simple, reliable and safe, atrial septal puncture under 45 degree of right anterior oblique view is an easily-mastered approach.

AlM: To investigate the efficacy of photodynamic therapy ( PDT) and intravitreal injection with ranibizumab on macular choroidal neovascularization ( CNV ) of pathologic myopia ( PM) .
METHODS: There were patients ( 32 eyes ) who were diagnosed as PM with CNV. Randomly selected 16 cases ( 16 eyes ) which were given the PDT treatment ( PDT group ) . The remaining were given both PDT and intravitreal injection with ranibizumab ( combination group) . There is no significant difference on macular edema between two groups. We analyzed the changes in the best corrected visual activity ( BCVA) , optic coherence tomograph ( OCT ) and fundus fluorescein angiography (FFA) before and 1, 6mo after treatment.
RESULTS:One month after the treatment in PDT group:the BCVA increased while the CMT decreased compared with that of pretreatment (P<0. 05). One month after the treatment in combination group: the BCVA increased while the CMT decreased significantly compared with that of pretreatment (P<0. 01);the changes of BCVA and CMT showed statistically significant between the two groups ( P<0. 05). Six month after the treatment in PDT group: the BCVA increased while the CMT decreased compared with that of pretreatment ( P <0. 05 ). Six month after the treatment in combination group: the BCVA increased while the CMT decreased significantly compared with that of pretreatment ( P <0. 01 ); compared with changes of BCVA and CMT in two groups, the difference was significant after treatment (P<0. 05). Compared 1mo with 6mo after treatment:there was no significant difference in the BCVA and CMT changes (P>0. 05). One month after treatment: in PDT group, FFA showed no leakage or reduced leakage of CNV in 11 eyes (69%), and the fundus remained leaky in 5 eyes ( 31%); in combination group, FFA showed no leakage or reduced leakage of CNV in 13 eyes (81%);the fundus remained leaky in 3 eyes (19%). Six month after treatment:in PDT group, FFA showed no leakage or reduced leakage in 10 eyes ( 62. 5%); the fundus remained leaky in 4 eyes ( 25%); two eyes ( 12. 5%) relapsed leakage; in combination group, FFA showed no leakage or reduced leakage of CNV in 15 eyes (94%);the fundus remained leaky in 1 eye (6%).
CONCLUSlON: Not only PDT but also PDT and intravitreal injection with ranibizumab can block CNV of pathologic myopia completely or partly, and reduce the danger causing descent of vision. Effects and the stability of the combination therapy is superior to PDT treatment.

Objective To summarize the risk factors of head up tilt test (HUTT) in children with vasovagal syncope,and provide theoretical reference for the diagnosis of vasovagal syncope.Methods The total of 340 children with headache and syncope were included in the study,all the cases received HUTT,including basic tilt table test and sublingual nitroglycerin test.And they were divided into HUTT positive group and HUTT negative group according to the results.The clinical information of two groups was analyzed by multivariate Logistic regression to summarize risk factors.Results The frequency of syncope in HUTT positive group was 2.3 ± 1.1,significantly higher than that in HUTT negative group (0.7 ±0.2),chest tightness and blurred vision ratios were significandy higher than those in HUTT negative group (84/186,48/186 vs.34/154,23/154).Single factor analysis showed,older than 12 years old,female,blurred vision,with history and genetic history of syncope,numerous of syncope,chest tightness,fatigue were related factors as positive results for HUTT.Multivariate Logistic regression analysis showed,older than 12 years old,female,with history and genetic history of syncope were independent risk factors of positive HUTF.β was 0.744,1.126,1.312,0.514 respectively,95％ CI was 1.132-5.968,1.985-5.040,1.366-9.677,1.683-6.532 respectively.Conclusion Age,gender,family history,history of syncope have important significance to predict HUTT results.
