ObjectiveTo investigate the diagnostic value of EUS-FNA for pancreatic masses and correlated influential factors. MethodsWe retrospectively analyzed the clinical data of 101 patients with pancreatic lesions who underwent EUS-FNA from January 2008 to January 2010. The clinical data enrolled 10 factors including patient gender, patient age, lesion location, lesion size, lesion characteristics, negative suction pressure, times of access, real-time cytological diagnosis, type of EUS and operators' experiences.ResultsThe overall diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of EUS-FNA were 85. 1％, 81.1％, 96. 3％, 98. 4％ and 65.0％, respectively. Univariable logistic regression analysis indicated that lesion size, lesion characteristics, negative suction pressure, operators' experience were correlated factors of EUS-FNA positive rate, while lesion size was the only correlated factor of EUS-FNA diagnostic accuracy ( OR =1. 984,95 ％ CI: 1. 141 ～ 3. 451, P =0. 015 ). Every 1 cm the lesion increased, by 1.67 times of opportunity the positive rate became, by 1.83 times of opportunity the accuracy was. The lesion size and lesion characteristics were independent correlated factors of EUS-FNA positive rate (OR=2.012, P=0.000; OR =10.218, P=0. 002). The positive rate of EUS-FNA in solid lesions was 10. 2 times of that in cystic lesions. Lesion size was the independent correlated factors of EUS-FNA diagnostic accuracy (OR =1. 984, P =0. 015 ). ConclusionEUS-FNA can effectively make a pathological diagnosis of pancreatic masses with high diagnostic accuracy and specificity. EUS-FNA diagnostic positive rate and accuracy were both positively correlated with pancreatic lesion size. EUS-FNA positive rate of solid pancreatic lesions is significantly higher than that of cystic lesions.

OBJECTIVETo study the clinical effect of development theory based acupuncture on early cerebral palsy (CP) infants with parafunctional sitting position.

METHODSTotally 120 early CP infants were randomly assigned to two groups equally, the treatment group and the control group. All received acupuncture combined with training rehabilitation. Patients in the treatment group adopted acupuncture based on infants development theory, while those in the control group were treated by head acupuncture. Sitting functional points in Gross motor function measure (GMFM) 88 were observed in different groups and infant patients of various types before and after treatment. Root mean square (RMS) signals of sitting correlated muscles (latissimus dorsi, erector spinae, rectus abdominis) were recorded by surface electromyography (sEMG). The effective rate was evaluated by Nimodipine method.

RESULTSCompared with before treatment, sitting functional points were significantly improved in the two groups (P<0.01). After treatment, it was higher in the treatment group than in the control group (P<0.01). The advance amplitude was higher in CP infants of the spastic type and the hypotonic type than other types (P<0.01). Along with sitting process, latissimus dorsi RMS signals were gradually tapered, erector spinae RMS signals were gradually enhanced, and rectus abdominis RMS signals were slightly weakened. Compared with the control group, latissimus dorsi RMS signals obviously decreased, and erector spinae RMS signals obviously increased in the treatment group after treatment (all P<0.01). The total effective rate was higher in the treatment group than in the control group (89.29% vs. 77.78%, P<0.05).

CONCLUSIONInfants development theory based acupuncture could effectively elevate dorsi-extensor muscles force, improve sitting position of 8 months to 1 year old CP infants with parafunctional sitting position.
