Objective Thymoma is associated with autoimmune diseases. We retrospectively analyzed the clinical characteristics of thymoma complicated systemic lupus erythematosus (SLE). Methods Patients were from Qilu Hospital Shandong University between June 2004 and June 2014, and satisfied classification criteria of American College of Rheumatology (ACR) classification criteria 1997 for SLE. Thymoma was diagnosed by chest CT scan. Results Nine cases were of thymoma complicated with SLE, with the male:female ratio of 1∶8. The age of SLE onset was (48±19) years, age of thymoma discovery was (47±19) years. The follow-up period was 3 to 10 years. Three cases (33%) were benign thymoma and underwent thymectomy and verified by histopa-thology test. One case presented thymoma 9 years after SLE, 5 cases (56%) presented SLE and thymoma simultaneously, 3 cases (33%) presented SLE after thymectomy. Clinical manifestations of SLE included 4(44%) skin lesions, 8(89%) polyarthritis, 5(56%) nephritis, 3(33%) leukocytopenia, 3(33%) throm-bocytopenia, 2 (22%) of interstitial pneumonia, 4 (44%) pleural effusion, no neuropsychiatric systemic lupus erythematosus. Nine cases (100%) were ANA positive, 7 (78%) were anti-dsDNA positive. Conclusion SLE complicated thymoma usually occurs in relatively older age, tend to present with multi-systemic presentations, and high percentage of anti-dsDNA positivity.

OBJECTIVEThis study was designed to investigate the prevalence, clinical characteristics and outcome of upper respiratory infection (URI) caused by Mycoplasma pneumoniae (MP) in children.
METHODSPharyngeal cultures for MP antibody were performed in 960 children with acute URI. The samples were randomly collected from the outpatient room or emergency room (Observed group). Of the Observed group, there were 232 cases under 1 year of age, and the remainder, were between 1-12 years old. The samples from 100 healthy children aged from 6 months to 12 years were used as the Control group. The prevalence of MP infection between the two groups was compared. The clinical manifestations and the outcome between the patients with MP positive and negative were compared.
RESULTSMP antibody was positive in 31.7% (304/960) of the Observed group but only 9.0% (9/100) in the Control group (P < 0.05). The URI patients under 1 year of age had a lower positive rate of MP than those over 1 year old (P < 0.05). Coughs and tonsillitis were more common (P < 0.05), but catarrh, gastroenteritic symptoms, herpes, and tetter were rare (P < 0.01) in URI patients with MP positive compared with those with MP negative. Pneumonia developed in 14.8% of the patients with MP positive but only 7.0% in those with MP negative (P < 0.01).
CONCLUSIONSMP is one of the main pathogens of acute URI in children. Acute pharyngotonsillitis symptoms are predominately presented in children with MP infection. MP infection was commonly seen in children over 1 year old and they are prone to develop pneumonia.

AIMTo investigate whether the selective AT1 receptor antagonist irbesartan exerts neuroprotective effect on focal cerebral ischemia in normotensive rats.
METHODSCerebral ischemia was induced by middle cerebral artery occlusion (MCAO) for 90 min followed by reperfusion, with the monitoring of laser Doppler flowmetry. To avoid the interaction with peripheral AT1 receptors, irbesartan was infused intracerebroventricularly (ICV) at a dose which effectively inhibited brain- but not vascular AT1 receptors. Neurological status was evaluated daily after MCAO. Rats were killed and brain samples were collected for the measurement of infarct size and immunohistochemical evaluation of apoptosis by deoxynucleotidyltransferase-mediated biotinylated UTP nick end labeling (TUNEL) and expression of activated Caspase-3 and the cleavage fragment of poly (ADP-ribose) polymerase (PARP).
RESULTSTreatment with irbesartan improved significantly the neurobehavioral functions after cerebral ischemia. The infarct size was reduced about 42% on day 7 after MCAO (P < 0.05). Meanwhile,irbesartan treatment significantly decreased the number of TUNEL-positive cells in the penumbra. The expression of activated Caspase-3 and the downstream cleavage fragment of poly (ADP-ribose) polymerase in the penumbra were also inhibited by irbesartan therapy on day 3 after transient cerebral ischemia.
CONCLUSIONAngiotensin AT1 receptor antagonist exhibits neuroprotection against transient cerebral ischemia in the brain. The neuroprotective effects in ischemic tissue may be associated with its inhibition of apoptotic cell death in the penumbra.

Objective To evaluate the short-term efficacy and safety of sevelamer hydrochloride in treating maintenance hemodialysis (MHD) patients with hyperphosphemia.Methods A multicenter,open-labeled,self-control study was performed.Phosphate binders were discontinued during a two-week washout period.Patients with more than 1.78 mmol/L serum phosphorus after two-week washout period were eligible for the trial.The dose was adjusted every two weeks as necessary to achieve serum phosphorus control. Sevelamer hydrochloride was administered to 138 MHD patients for 10 weeks and a second two-week washout period followed.Results A total of 111 from 138 patients fulfilled the whole 14-week study. Mean serum phosphorus and calcium-phosphate products starte to decline after two-week sevelamer hydrochloride treatment. By the end of 10-week sevelamer hydrochloride treatment, mean serum level of phosphorus [(1.85±0.50) vs (2.57±0.54) mmol/L,P<0.01],calcium-phosphate product [(4.16± 1.72) vs (5.79 ± 1.50) mmol2/L2,P<0.01 ] and low density lipoprotein [(1.64±0.76) vs (2.31 ±0.87) mmol/L,P<0.01] were significantly decreased,while the adjusted serum level of calcium and serum intact parathyroid hormone kept steady.Both serum phosphorus and calcium-phosphrus product increased after the second washout period, but the levels were still lower as compared to pre-treatment [(2.26±0.71) vs (2.57±0.54) mmol/L; (5.12±1.63) vs (5.79±1.50) mmol2/L2,P<0.01].Of the 138 patients involved,214 episodes in 106 patients and 121 episodes in 89 patients were reported as adverse events and adverse drug reaction respectively. Gastrointestinal symptoms,of which most were mild or moderate,happened to 68.1% (94/138) patients. Conclusions Sevelamer hydrochloride can control serum phosphorus and reduce the levels of calcium-phosphorus product and cholesterol.Slight gastrointestinal symptoms like constipation are common during the treatment.

To investigate the correlation between methylation and expression of multidrug resistance (mdr1) gene, restriction endonuclease HpaII combined with competitive PCR technique was used to quantitatively detect the methylation status of two CCGG sites located at -110 and -50 bp (region I and II) up to the transcription start site in mdr1 promoter in 54 AL and 9 MM patients. Semi-quantitative RT-PCR was used to detect the expression level of mdr1 gene. The results showed that inverse correlation between methylation rate of either region or total methylation rate and expression of mdr1 gene was observed. The correlation in the region I (r = -0.64) was closer than that in the region II (r = -0.4). High expression rate of mdr1 ascended significantly in low methylation group (n = 36) (P < 0.001). In comparison with chemotherapy sensitive group (n = 8), the methylation rate in refractory AL patients (n = 16) was lower (P = 0.05) in the region I, P < 0.05 in the region II and total regions. Comparing with the untreated patients (n = 36), the methylation rate in the region I and total methylation rate were lower in the patients with chemotherapy (n = 14) (P < 0.05). The methylation rate in the region II was also decreased after chemotherapy, however, no statistical significance was shown (P > 0.05). Increased mdr1 expression level accompanying with decreased methylation rate after chemotherapy was found, although no significant difference was shown (P = 0.06). It is concluded that the expression level of mdr1 gene was associated with the methylation status of CCGG in -110 and -50 bp upstream to the transcription start site, especially the -110 site. In both the patients treated with chemotherapy and the refractory patients, the methylation level of mdr1 gene decreased relatively. The rising expression of mdr1 gene after chemotherapy was associated with the decrease of methylation level.

OBJECTIVETo observe the incidence of elimination delay in high dose methotrexate (HDMTX) therapy, its side effects and influence to next course of chemotherapy and analyze the relationship between the dosage, the duration of MTX infusion and the morbidity of the elimination delay.
METHODSA total of 121 childhood acute lymphoblastic leukemia (ALL) (497 infusions of HDMTX) were analysed in this study. The elimination delay rate and the adverse effects in different dose groups (3 g/m2 vs 5 g/m2) and different infusion duration groups (7 h vs 24 h) were compared. The adverse effect evaluation was based on the World Health Organization (WHO) Toxicity Grading Criteria. The rescue dosages of calcium folinate (CF) among these groups were compared through CF/MTX index.
RESULTSThe overall morbidity of elimination delay was 12.1% with a relative risk of 30.6% for the first time. The relative risk for the second time of occurrence was increased to 45.9% (P < 0.01) and it was not significantly increased for the third time (35.3%). Children with elimination delay had lower platelet count (P < 0.01) and higher CF rescue dosage (P < 0.01), while the damage of oral mucous membrane was more severe (P < 0.05) and the next course of chemotherapy would be postponed for a median of 4 days in 3 g group. There was no significant difference in elimination delay rates between 3 g and 5 g groups (12.1% vs 12.0%, P > 0.05), and between 7 h and 24 h MTX infusion groups (13.6% vs 11.9%, P > 0.05). The only side effect occurred in 5 g group was gastrointestinal morbidity. The CF/MTX index of 5 g group without elimination delay was less than that of 3 g group (P < 0.01).
CONCLUSIONElimination delay in HDMTX therapy accompanies the suppression of bone marrow and damage of oral mucous membrane, which need more CF rescues and will postpone the following course of chemotherapy. Elimination delay is not associated with the duration of the infusion and the dosage of MTX within the range of 3 approximately 5 g/m2 but there are individual differences.
