Meanwhile,they improved the teaching links in theoretical teaching and experimental teaching and emphasized on students' feed-back,which provided references for teaching of medical cell biology course.

The cyanuric chloride linkers have been used for cyclizing polypeptide, but not used for α-conotoxin, the peptides with rich disulfide bonds and more amino acid residues. In this study, cyclic peptides c[A10L]PnIA-1-4 were synthesized efficiently by lysine assisted cyanuric chloride linkers with 28.92%-52.00% yields. The activity evaluation showed that the IC₅₀ values of c[A10L]PnIA-1 against α7 and α3β2 nAChR subtypes were 5 and 7 times higher than [A10L]PnIA respectively, and the subtype selectivity was maintained. The results of circular dichroism show that this cyclization method had no significant effect on its secondary structure. Compared with the commonly used head-to-tail cyclization in conotoxin cyclization, this method has the advantages of rapid reaction and high yield, which is expected to be further applied to the cyclization study of various α-conotoxins.

Objective To discuss the value of prenatal ultrasound and MRI in diagnosis of fetal agenesis of corpus callosum (ACC). Methods Sixty-seven fetuses from Hubei Maternal and Children's Hospital performed fetal MRI from July 2013 to December 2014 were included in this study. All fetuses (67 cases) with suspected ACC were studied with a 1.5T MR unit within 3 days after ultrasound examination. Prenatal ultrasound and MRI findings were studied. Results All the 67 ACCs previously suspected on ultrasound were confirmed by MRI. Among the 67 ACCs, 58 cases were complete ACC and 9 cases were partial ACC. Corpus callosum body and/or splenium absence was found in all 9 partial ACC cases. In all cases, on MRI, corpus callosum complete or partial absence was showed on the median sagittal images, and mild to moderate ventriculomegaly and abnormal morphology in lateral ventricle was shown on the axial or coronary images. Conclusions MRI has high value in diagnosis of ACC. When ACC is found or suspected by ultrasonophy, MRI examination is suggested to confirm the diagnosis.

Objective To evaluate the effectiveness of blood gas analysis in samples from two regions.Methods 112 patients with APACHE Ⅱ scores 27 ～ 43 were taken arterial blood from dorsalis pedis artery and femoral artery respectively. Compare the clinical effect of the samples. Results There is no statistically significant difference between results of two blood collection methods ( P ＞ 0. 05 ), While there is statistically significant difference in puncture success ( 110 vs 100, χ2 = 14.23, P ＜ 0. 05 ), vein mistaken injury, hematoma formation, thrombosis, and compression time ( 12 vs 1,7 vs 0,6 vs 0,5.5 ±0.7 vs 2.5 ±0.5 ;χ2 =9.32,5.99,4.85,t = 38. 06, P ＜ 0. 05 ). Conclusions Blood collection method should be determined by the different situation of critically ill patients. Femoral artery blood sample should be taken with caution in order to prevent complication and improve quality of nursing care.

OBJECTIVETo analyze the safety and efficacy of anti-CD20 monoclonal antibody in treatment of severe pediatric systemic lupus erythematosus (PSLE).

METHODThe diagnosis of PSLE was made according to the criteria for the classification of systemic lupus erythematosus revised by the American College of Rheumatology in 1997. Severe cases with PSLE was selected by the following criteria: age ≤ 16 years, number of important organs involved > 1, SLEDAI score > 10 points and poor response to conventional immunosuppressive treatment. These patients received 2 doses of 375 mg/m(2) rituximab (RTX), 2 weeks apart. Clinical, laboratory findings and drug side effects were recorded at RTX initiation, 2 weeks, 1 month, 3, 6 and 12 months after infusion.

RESULTA total of 20 patients. Male to female ratio was 1:3, were enrolled. They were 5-16 years old. The course of disease was (3.0 ± 2.5) years (range: 1 month-7 years), patients were followed up for 12 - 36 months [median: (27.0 ± 7.8) months]. Delirium and cognitive disorders were significantly improved in 10 cases of lupus encephalopathy after 1 month. Lupus nephritis in children were eased slowly, 14/15 patients with lupus nephritis were improved after 2-3 months. Four cases of lupus pneumonia were significantly improved within 1 month. Decreased blood cells counts were relieved at 1 month in 16/18 cases. Cellular immune function was assessed 2 weeks after application of anti-CD20 monoclonal antibody; we found B-cell clearance in 19 patients (95%). B lymphocyte count of 18 patients (90%) was restored within one year. SLEDAI score was reduced obviously. Dose of corticosteroid ranged from (45.0 ± 4.7) mg/m(2) before drug use to (12.0 ± 2.7) mg/m(2) 12 months later (P < 0.001). After the drug use, 5 patients had pneumonia within 6 months; 2 cases who suffered from aspergillus pneumonia and Pneumocystis carinii pneumonia respectively were severe. They accepted mechanical ventilation and anti-inflammatory support after being transferred to the intensive care unit, and their conditions improved at last. No death occurred. In 2 patients the disease recurred with B-cell recovery after 15 months and 18 months. Administration of another cycle of rituximab resulted in remission again in one case but not in the other.

CONCLUSIONAnti-CD20 monoclonal antibody is effective and safe in treatment of severe PSLE. But severe infections may occur in some cases. Focusing on prevention and early treatment can reduce the probability of adverse reactions.

OBJECTIVETo investigate the clinical features and genetic diagnostic method of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).

METHODSA systematic study on the clinical manifestations, neuroimaging characteristics, therapeutic measures and molecular genetics was performed. An investigation on the onset and hereditary pattern of the family was also done.

RESULTSThe main clinical features including poor memory and history of stroke were found. And no risk factors of hypertension and arteriosclerosis were found. A positive family history was confirmed. Neuroimaging examination showed multiinfarct lesions and leukoencephalopathy. All these features are in conformity with those of CADASIL. A mutation in the third and fourth exon of the NOTCH3 gene was identified in the 10 cases of 4 generations. The clinical or subclinical onset in the 10 cases was consistent with classical autosomal dominant inheritance.

CONCLUSIONThe clinical and molecular genetic features of the family accord with CADASIL.

OBJECTIVETo report a rare variant of t(15;17), ins(17;15)(q21;q14q22) in an acute promyelocytic leukemia (APL) patient and the results of cytogenetic and molecular genetic studies.

METHODSChromosomes were prepared after 24 hours culture of bone marrow cells and peripheral blood cells. R-banding technique was used to analyze karyotypes. Chromosome painting analysis was performed using whole chromosome paints for chromosomes 15 and 17. PML-RAR alpha and RAR alpha-PML fusion transcripts were detected by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSKaryotypic analysis using both specimens from bone marrow and peripheral blood leukemic cells revealed 15q- and 17q+. Chromosome painting analysis confirmed that the karyotypic abnormality was ins(17;15). PML-RAR alpha fusion transcript (S type) was detected by RT-PCR, while RAR alpha-PML fusion transcript was not detected.

CONCLUSIONChromosome painting and RT-PCR are reliable methods for characterization of the insertion involving chromosomes 15 and 17 in APL patients.
