It was showed that the ir-ANP levels of the patients with left to right shunt were higher than those of control (P0.05). The iir-ANP levels of patients with HYHA II degree were increased significantly (P

Objective To explore the clinical significance and changes of tumor necrosis factor-?(TNF-?)and interleukin-6(IL-6)level in children with acute viral myocarditis(AVM).Methods TNF-? and IL-6 level in serum from 53 AVM children and 20 healthy children were measured by radio-immunoassay and enzyme-linked immunosorbent assay(ELISA).The relation between the levels of TNF-? and IL-6 in serum with the occurrence and development in acute viral myocarditis was analyzed.Results Thirty-two were males and 21 females in the 53 AVM children.The ages ranged from 3-11 years old.There were 12 males and 8 females in control group.The serum level of TNF-? and IL-6 were(526.7?32.9),(3.23?0.53)mg/L in AVM group and(383.1?27.5),(1.63?0.22)mg/L in control group.There were significant difference between the 2 groups(Pa

Objective: To assess the surgical techniques and surgical outcomes of temporoparietooccipital and parietooccipital disconnection. Methods: The authors conducted a retrospective review of clinical, neuropsychological, EEG, imaging data in 16 patients with intractable epilepsy who underwent temporoparietooccipital and parietooccipital disconnection between April 2008 and October 2011. Of the 16 cases, 12 were males and 4 were females. The age of seizure onset was from 0.1 to 27 years (average 6.6) and disease duration of 0.1 to 18 years (average 7.5). The surgery was performed between the age of 3 and 37 years (average 14.1). Nine patients underwent temporoparietooccipital disconnection, 5 patients parietooccipital disconnection and 2 patient parietooccipital disconnection and temporal lobotomy. Results: After a mean follow-up of 1.6 years (range 0.5–3.9 years), 13 patients (81%) were seizure free, 1 patient had Engel Class II seizure outcome and 2 patient had Engel class III outcome. Two patients exhibited severe brain swelling and one patients had second resective operation with good recovery. None of the patients developed new motor defi cits postoperatively and there was no mortality. Conclusion: Temporoparietooccipital and parietooccipital is a safety and effective epilepsy surgery procedure for patients with epileptic zone localization to the posterior quadrant on one side. The results of surgical disconnection for posterior quadrantic epilepsy have yielded excellent seizure outcomes in 81% of the patients, with no mortality or major morbidity.

Objective To investigate the clinical effect and pathogenesis of tiopronin in treating acute pancreatitis complicated with liver damages. Methods Eighty-one patients with acute pancreatitis complicated with liver damages were randomly divided into two groups. The control group (40 cases) received routine treatment, and the treatment group (41 cases ) received routine treatment and tiopronin. The liver function, pancreatic enzyme indexes and C-reactive protein (CRP), the length of hospital stay was recorded. Results After 8 days' treatment, the liver function improved, and the levels of pancreatic enzyme indexes and CRP were decreased significanfly in both groups, and these changes were more obvious in treatment group (P <0.05). The length of hospital stay of mild acute pancreatitis in treatment group was significantly shorter than that in control group [ (8.6 ± 2.7 ) d vs. ( 13.8 ± 3.5 ) d ] (P < 0.05 ). Conclusions Tiopronin has beneficial effects in treating acute pancreatitis complicated with liver damages,and it has a therapeutic effect in acute pancreatitis at the same time. The mechanism may be related with the inhibition of inflammatory mediators, oxygen free radicals scavenging and other effects.

Objective To evaluate the clinical effects and adverse reaction of raltitrexed combined with radiation for esophageal carcinoma in elderly patients.Methods Sixty patients were randomly divided into two groups by the envelope method, 30 patients in experimental group received raltitrexed combined with radiotherapy and 30 patients in control group received radiotherapy only.Patients in both groups received conventional radiotherapy with a total dose of 56-60 Gy/28-30 F.In experimental group, raltitrexed 2.6 mg/m2 was administered concurrently with the radiotherapy on d1 and d22.Two cycles of concurrent chemotherapy were administered during radiotherapy.The short-term effects, survival times and adverse reactions of the two groups were compared.Results The total effective rates of experimental group and control group were 93.3% and 73.3%, respectively, and there was statistically significant difference between the two groups (χ2=4.320, P=0.038).The median survival times of experimental group and control group was 24.0 months and 12.0 months, respectively, and there was statistically significant difference by Log-rank test (χ2=6.048, P=0.014).The major adverse reactions of grade 3-4 in experimental group and control group were radiation-induced esophagitis (10.0% vs.3.3%;χ2=0.268, P=0.605), leukopenia (13.3% vs.10.0%;χ2=0.000, P=1.000), thrombocytopenia (3.3% vs.0;P=1.000), nausea and vomiting (6.7% vs.0;χ2=0.517, P=0.472), and the differences were not statistically significant.Conclusion Raltitrexed combined with radiotherapy can enhance the short-term effect and prolong the survival time for the elderly esophageal carcinoma patients, and the adverse reactions are mild.It is worthy of further clinical study.
