ABSTRACT

Objective:To observe the Toll-like receptor 4(TLR4)and its negative regulating factorInterleukin-1 receptor-associated kinase-M(IRAK-M)in colonic mucosa of rats with experimental ulcerative colitis(UC), and to discuss the mechanism of the Chinese medicine Sishenwan. Method:The 90 Wistar rats were randomly divide into six groups, blank group, model group, sulfasalazine group(0.36 g·kg-1), Sishenwan low, medium and high-dose group(2.5, 5, 10 g·kg-1), 15 cases in each group. A rat model of UC was prepared by using a solution of trinitrobenzenesulfonic acid/ethano.The histopathological changes of colon were observed by hematoxylin-eosin (HE) staining. The contents of serum free triiodothyroid acid (FT3), serum free thyroxine (FT4), immunoglobulin (Ig) E and interleukin (IL)-2 were determined by radioimmunoassay. The activity of superoxide dismutase (SOD) in rat serum was determined by xanthine oxidation method. The activity of malondialdehyde (MDA) in serum of rats was determined by thiobarbituric acid (TBA) colorimetry. Result:Compared with blank group, intestinal mucosal injury score of rats in model group was significantly increased (PP3, FT4, IL-2 and SOD were significantly decreased (PPPPPP3, FT4, IL-2, and SOD contents were significantly increased (PPPPPConclusion:The unbalanced expressions of TLR4 and its negative regulating factor IRAK-M are connected with the pathogenesis of UC.Sishenwan can cure UC and control the expression of TLR4 and promote the expression of IRAK-M.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the Z scores for growth and development, physical fitness, and the relationship between them in preschool children in Yantai City, China, and to provide scientific evidence for health care in children.</p><p><b>METHODS</b>A total of 362 children aged 3 to 4 years, whose data were recorded in the National Physical Fitness Survey in Yantai in 2010, were included in the study. Z scores for weight-for-age, height-for-age and body mass index-for-age were calculated. The relationship between Z scores and physical fitness was determined by Pearson's correlation analysis.</p><p><b>RESULTS</b>The mean Z scores were all positive numbers. The prevalence rates of underweight and growth retardation were very low, but that of obesity was relatively high (up to 16.5% in 4-year-old boys). There were differences in physical fitness between children of different ages and between boys and girls (P<0.05). The Z scores showed correlation with some physical fitness indices (P<0.05), but they were not closely correlated as the value of r was not more than 0.30.</p><p><b>CONCLUSIONS</b>Z scores for growth and development remain at relatively high levels in preschool children in Yantai. The physical fitness is associated with age and gender in these children. There are weak correlations between Z scores and some physical fitness indices. Effective measures should be taken to adjust dietary habits and promote exercise for children, thus preventing obesity and improving physical fitness.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study neonatal Streptococcus agalactiae (GBS) infection in The Children's Hospital of Gansu Province through Polymerase Chain Reaction(PCR) Array.</p><p><b>METHOD</b>After obtaining the informed consent from parents or guardians, blood samples of 286 neonates were collected and studied in The Children's Hospital of Gansu Province from June 2011 to January 2012. DNA of the selected samples was extracted through the method of 5% Chelex-100 + 0.5% NP40 solution. Twenty-five genes were ultimately selected and then 25 pairs of primers were designed respectively through primer-BLAST tool of NCBI database.For every primer, PCR conditions were optimized through the identified GBS, and 25 pairs of primers were arrayed as to be used to study neonatal GBS infection.</p><p><b>RESULT</b>The results of PCR Array showed that the 14 samples were detected positive, accounting for 4.90% of all the selected specimens. As for neonatal GBS infection, the positive rate was 4.55% within 7 days after birth and 5.19% in those older than 7 days. The positive rate of 53 preterm infants was 5.66%. The follow-up survey showed that none of the cases died.</p><p><b>CONCLUSION</b>In the Children's Hospital of Gansu Province neonatal GBS infection rate was 4.90%, which is similar to the previous domestic reports, but is lower than the reports from Europe and the United States.Studies have shown that the gene expression related to immune evasion has a higher frequency. The present study suggests that the strategy of GBS immune adaptation may play an important role in neonatal GBS infection.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the safety and efficacy of nilotinib in chronic myelogenous leukemia (CML) patients with resistance or intolerance to imatinib.</p><p><b>METHODS</b>Thirty-five CML patients after imatinib failure or intolerance received oral administration of 400 mg nilotinib twice daily. The overall survival, hematologic and cytogenetic responses, as well as adverse events were evaluated.</p><p><b>RESULTS</b>The median duration of nilotinib therapy was 11 (1 - 23) months, with a median follow-up of 19 months. Nonhematologic adverse events were mostly of grade 1-2. The most common ones possibly related to nilotinib were increase of bilirubin (76%) and rash (46%). Grade 3-4 hematologic adverse events includes thrombocytopenia (37%), neutropenia (26%) and anemia (26%). Nilotinib was proved to be well-tolerated in this study. Grade 3-4 hematologic adverse events happened more frequently in advanced phase CML. The rate of major cytogenetic response in chronic phase (CP) CML was much higher than those in advanced CML (38.5% vs 22.2%). The median time to major cytogenetic response was 3 months. The estimated overall survival at 18 months was (93.5 +/- 1.0)%.</p><p><b>CONCLUSION</b>Nilotinib is a more effective and safe treatment option for imatinib-resistant or -intolerant CML-CP patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the safety and efficacy of imatinib in treatment of chronic myeloid leukemia (CML) patients.</p><p><b>METHODS</b>From December 2003 to March 2007, 151 patients entered Glivec International Patient Assistance Program (GIPAP) in our center and received imatinib therapy. The overall and progression free survival, hematologic, cytogenetic and molecular response, and adverse events were evaluated. The factors associated with outcome of imatinib therapy were also analysed.</p><p><b>RESULTS</b>One hundred and forty-two patients were evaluable with a median follow-up duration of 21.5 (6 -78) months. (1) The rate of cumulative complete hematologic response (CHR), major cytogenetic response (MCyR), complete cytogenetic response (CCyR) and complete molecular response (CMoR) in chronic phase (CP) CML patients were 96.9%, 82.6%, 76.1% and 29.4%, respectively. These rates were significantly higher in patients with CP than in those with accelerated phase (AP) and blast crisis (BC) (P < 0.0001). (2) The overall survival (OS) rates at 1, 2 and 3 year were 100%, (97.3 +/- 1.9)% and (95.8 +/- 2.4)% for CP patients, they were (84.7 +/- 8.2)%, (77.0 +/- 10.4)% and (69.3 +/- 11.9)% for AP patients, and (62.9 +/- 8.9)%, (41.9 +/- 9.2)% and (28.5 +/- 9.1)% for BC patients, respectively (P < 0.0001). The progression-free survival (PFS) rates at 1, 2 and 3 year were (98.9 +/- 1.1)%, (93.9 +/- 2.7)%, (93.9 +/- 2.7)% for CP patients, (68.9 +/- 10.6)%, (61.3 +/- 11.9)%, (61.3 +/- 11.9)% for AP patients, (36.4 +/- 8.8)%, (25.4 +/- 8.1)%, (10.1 +/- 8.2)% (P < 0.0001) for BC patients respectively. (3) Among 92 CP patients, the rates of MCyR and CCyR in newly diagnosed patients were significantly higher than those in interferon therapy failure patients (P = 0.015, P = 0.010). Patients obtained CCyR at 12 months after the initiation of imatinib treatment were associated with longer PFS (P = 0.0099). According to the Sokal scoring system, the rates of MCyR and CCyR in low-risk patients were significantly higher than those in intermediate-risk and high-risk patients (P = 0.0013, P = 0.0024). Sokal score was also significantly associated with disease progression (P = 0.0467). (4) The adverse events of imatinib were moderate and tolerable.</p><p><b>CONCLUSIONS</b>Treatment of CML patients in CP with imatinib can induce high hematologic, cytogenetic and molecular response and overall survival, but can not do satisfactorily for patients in AP and BC.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To make prenatal dignosis of X-linked adrenoleukodystrophy (ALD) for the prevention of the disease.</p><p><b>METHODS</b>Eighteen amniocenteses were performed on 17 suspected carriers of X-ALD during 18-30 gestation weeks. The very long chain fatty acids (VLCFAs) levels of cultured amniocytes were tested by gas chromatography-mass spectrometry (GC/MS). The plasma VLCFAs levels were measured in 8 of the 18 prenatal diagnosed children when they were born or after abortion. ABCD1 gene mutation analysis was carried out in 8 cases by PCR and sequencing. ALDP of amniocytes was tested by Western blotting in 2 cases from a family, one female, another male, and the VLCFAs of cultured amniocytes were increased in both of them.</p><p><b>RESULTS</b>Among the 18 fetuses, 10 were males and 8 were females. The VLCFAs levels of the cultured amniocytes were increased in 3 males and 4 females. The postnatal plasma VLCFAs were normal in 5 cases with normal VLCFAs levels of amniocytes, and increased in 3 cases with high VLCFAs levels of amniocytes. ABCD1 gene mutations were found in 4 cases with high VLCFAs levels of amniocytes, no mutation was found in other 4 cases with normal VLCFAs levels of amniocytes. ALDP of amniocytes could be detected in the female with high VLCFAs levels of amniocytes, and it could not be detected in the male with high VLCFAs levels of amniocytes. Three male fetuses with high VLCFAs levels of amniocytes were aborted. The others who were born were normal clinically so far.</p><p><b>CONCLUSION</b>The prenatal diagnosis is very important for the prevention of ALD. Amniocyte VLCFAs level analysis combined with ABCD1 gene mutation analysis and ALDP test could make a proper prenatal diagnosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To describe the clinical manifestation and the EEG, CT and MRI findings of hepatic encephalopathy (HE).</p><p><b>METHODS</b>The clinical manifestations and the plasma ammonia levels were analyzed in 17 patients with HE, who underwent EEG, CT and MRI examinations.</p><p><b>RESULTS</b>Fifteen patients had abnormal EEG findings characterized by lowered basic rhythm, moderate to high amplitude theta wave activity, and sporadic delta wave and triphasic wave. Fourteen patients had abnormal MRI findings, including increased signal in the bilateral globus pallidus (14/17), putmen(4/17) and tegmentum of the midbrain (7/17) in T1WI without corresponding alterations in the signal intensity in T2WI. T2 FLAIR demonstrated increased signal in the bilateral white matter of the cerebral hemispheres. CT identified no corresponding alterations in the signal intensity.</p><p><b>CONCLUSION</b>Abnormal EEG findings or MR signals in the brain are common in patients with HE. EEG allows detection of abnormal waves, and MRI may help identify such lesions, which all help in the diagnosis of HE.</p>

ABSTRACT

<p><b>OBJECTIVE</b>X-linked adrenoleukodystrophy (X-ALD) is the most common inherited disorder of peroxisomal metabolism which is characterized by demyelination of central nervous system, impaired adrenal cortex and abnormal accumulation of very long chain fatty acids in body fluid and tissues. In this study, the clinical features and the genotype-phenotype relationship were investigated so as to help early diagnosis.</p><p><b>METHODS</b>Clinical data of 89 Chinese patients with X-ALD were analyzed and mutation spectrums in 53 of the patients were investigated by polymerase chain reaction and DNA sequencing.</p><p><b>RESULTS</b>Of the 89 cases, 60 (67.4%) had childhood cerebral ALD (CCALD, mean age of onset was 6.5 years, range 2 - 10 years), 18 (20.2%) had adolescent cerebral ALD (ACALD, mean age of onset 12.1 years, range 11 - 19 years), 7 (7.9%) had adrenomyeloneuropathy (AMN, mean age of onset 23 years, range 6 - 39.5 years), and two cases were asymptomatic and another 2 had simple Addison's disease only. CCALD was the most common and severe phenotype, visual impairment was the most common initial symptom in CCALD and ACALD patients. Twenty four cases (63%) in whom hydrocortisone and ACTH were measured showed adrenal insufficiency. Forty five different mutations were identified in 53 patients. Missense mutations were the most common. No hotspot mutation was found in these patients and 1415delAG, the most frequent mutation found worldwide seemed not to be the real "hotspot" in these Chinese patients. The same phenotype may be due to diverse genomic mutations. A single mutation may result in different phenotypes even within a family.</p><p><b>CONCLUSION</b>The phenotype distribution, initial symptom and gene mutation spectrum of Chinese patients may not be completely consistent with those in other countries. The clinical phenotype of the disease had no definite relationship with the nature of gene mutations.</p>

ABSTRACT

<p><b>OBJECTIVE</b>X-linked adrenoleukodystrophy (X-ALD) is the most common peroxisomal disorder characterized by progressive demyelination of the central nervous system, adrenal cortex insufficiency and accumulation of saturated very long chain fatty acids (VLCFAs) in tissues and body fluids due to the impaired beta-oxidation in peroxisomes. X-ALD shows a wide range of phenotypic variation. Childhood cerebral form (CCER) is the most common phenotype with severe neurological symptoms and often the average interval from onset to total disability or death is 3 years. So far no effective treatment is available for the underlying defect. Screening for carriers of mutated relevant gene and prenatal diagnosis are very important for the prevention of the disease. In this study, the authors explored the method of carrier screening and prenatal diagnosis of X-ALD.</p><p><b>METHODS</b>The plasma VLCFAs levels of 83 suspected carriers for ALD were determined by using GC/MS and ABCD1 gene mutational analysis was performed in 31 of them. Amniocentesis was performed in 9 suspected carriers for ALD during 18 - 30 gestational weeks. The VLCFAs level of cultured amniocytes was tested with GC/MS. ABCD1 gene mutational analysis was performed on two cases (one was a male and the other a female) whose VLCFAs levels of amniocytes were found elevated. The plasma VLCFAs levels were measured in five of the nine prenatally diagnosed children when they were 1 day to 3.5 years old.</p><p><b>RESULTS</b>Fifty-one of 83 suspected carriers had high plasma VLCFAs levels; 29 of 31 suspected carriers showed ABCD1 gene mutation. Among the nine fetuses, four were males and five were females. The VLCFAs levels of the cultured amniocytes were high in two cases, one was female and the other a male. ABCD1 gene mutational analysis of these two cases showed a 871G > A (E291K) mutation and a 726G > A (W242X) mutation, respectively, which confirmed the biochemical result. The VLCFAs levels were normal in the rest of cases and five of them were confirmed by postnatal plasma VLCFAs assay.</p><p><b>CONCLUSION</b>The carrier screening and prenatal diagnosis are very important for prevention of the X-ALD. Only the combined use of plasma VLCFAs level analysis and ABCD1 gene mutational analysis could detect X-ALD carriers correctly. ABCD1 gene mutational analysis and postnatal plasma VLCFAs level test verified that amniocytes VLCFAs level analysis is a reliable prenatal diagnostic method for this disease.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study whether all-trans retinoic acid (ATRA) combined with arsenic trioxide (As(2)O(3)) in acute promyelocytic leukemia (APL) treatment could further improve the clinical and molecular remission rate.</p><p><b>METHOD</b>Thirty one newly-diagnosed APL patients of whom 15 were males, 16 females and median age 35.4 years entered into the study. They were treated with ATRA 25 mg x m(-2) x d(-1) combined with As(2)O(3) 0.16 mg x kg(-1) x d(-1) until complete remission (CR). The doses were adjusted according to white blood cell (WBC) counts, occurrence of RA syndrome and the status of liver function. CR rate, time of reaching clinical and molecular remission and side effects were observed.</p><p><b>RESULT</b>Two patients died 2 approximately 3 days after the treatment due to intracranial hemorrhage, and 29 (93.5%) achieved CR. The average time for achieving CR was 25.1 +/- 3.9 days. Hyperleukocytosis emerged in 66.5% and hepatic damages in 65.5% of the patients, they were ameliorated within one week after reduction of the As(2)O(3) dose or its suspension. The PML/RAR alpha fusion gene that was positive in all 29 patients before treatment turned negative only in 3 cases (10.3%) after obtaining CR (CR1) and in 10/13 cases (77%) after consolidation treatment. Up to now (1-8 months follow-up), all 29 patients remain in CR1.</p><p><b>CONCLUSION</b>ATRA combined with As(2)O(3) in de novo APL treatment can yield a high CR rate without intolerable side effects. Long term effect needs further observation.</p>
