RESUMEN
Objective To explore the diagnostic value of MSCT in tumors of intra-abdominal cryptorchidism in children.Methods MSCT findings of 8 children with tumors of intra-abdominal cryptorchidism confirmed by surgery and pathology were analyzed retrospectively.Results Six tumors located in the right,2 (1 tumor of left cryptorchidism turned to the right abdominal) in the left.Eight children showed ovoid soft tissue tumor in abdomen.Three children displayed the long axis of the tumors consistent with regular descending course of embryonic testes.Six teratomas manifested as the cystic and solid mass with fat,calcification (ossification) insidey.Two yolk sac tumors manifested as the large cystic and solid mass with irregular necrosis and abundant tumor vessels.Conclusion The pathologic types of tumors for intra-abdominal cryptorchidism in children are different from adult.Most of them are teratomas or yolk sac tumors,and have some characteristics in MSCT.MSCT is helpful in diagnosis of tumor for intra-abdominal cryptorchidism with medical history.
RESUMEN
Objective To evaluate the value of imaging examination and diagnosis of airway foreign body in children. Methods 218 of airway foreign bodies confirmed by bronchoscopy were retrospectively analyzed in terms of clinical and imaging data. Results 218 patients included 140 males and 78 females. Their ages ranged 6 months to 12 years(mean,19.2 months). All patients had conventional radiographs on frontal chest films,neck lateral films and fluoroscopy. 34 cases underwent 64-slice spiral chest CT examination. According to the location of the foreign bodies,29 cases were in throat and subglottic,55 cases in trachea and 134 cases in bronchus(79 cas-es in the right,55 cases in the left). According to the character of the foreign bodies,5 cases were metal,29 cas-es in bone,93 cases in peanuts,59 cases in seeds,22 cases in fruits and vegetables and 10 cases in others respec-tively. Thirty-fourcases showed a direct sign of the foreign body and 177 cases showed the indirect signs. 34 cases on CT examination directly were showed foreign body in the tracheal bronchi. The diagnostic accuracy of CT exami-nation was 100%. Conclusions X-ray photograph and fluoroscopy were the first choice for aspiratory foreign bod-ies in children. CT examination is an important supplementary method when conventional X-ray examination is neg-ative.
RESUMEN
Objective To analysis effect of breviscapine on serum and copeptin, NT-proBNP, HIF-1αand IMA in patients with acute ischemic brain vascular disease.Methods 42 patients who were diagnosed with acute ischemic brain vascular disease were collected and randomly divided into experimental group and control group, each group had 21 cases.All patients were given conventional treatment of Western medicine, on this basis, control group was given vinpocetine injection 20 mg, once daily intravenous drip;experimental group given Dengzhan flower Suting injection 20 mg, once daily intravenous drip; continuous treatment for 2 weeks.Before and after the treatment, the serum levels of copeptin, HIF-1α, NT-proBNP and IMA were detected in two groups.ResuIts Compared with control group, patients in experimental group treatment effect was better, as follows: serum copeptin content decreased significantly ( P<0.05 ) .Serum NT-proBNP levels decreased significantly ( P<0.05 ) .Serum levels of HIF-1αcontent decreased significantly (P<0.05).Serum ACB value increased significantly (P<0.05).ConcIusion Breviscapine can reduce the acute ischemic brain vascular disease patients serum copeptin, NT-proBNP, HIF-1αand IMA content, and has good therapeutic effect in patients with acute ischemic cerebral vascular disease.
