OBJECTIVETo observe the effect of Qianliean Pill (QP) on inflammatory factors such as IL-1β, IL-10, and tumor necrosis factor α (TNF-α) in chronic nonbacterial prostatitis (CNP) model rats, and to explore its therapeutic mechanism.
METHODSCNP rat model was established by castration and estradiol benzoate injection. Totally 50 rats were randomly divided into 5 groups, i.e., the model group, the positive medicine group, the high dose QP group, the medium dose QP group, and the low dose QP group, 10 in each group. Besides, 10 normal rats were recruited as a normal control group. Since the 8th day of castration, Pulean Tablet (PT) at 10. 80 g/kg was administered to rats in the positive medicine group by gastrogavage. QP at 11.00, 5.50, and 2.75 g/kg was administered to rats in high, medium, and low dose QP groups by gastrogavage. Distilled water at 2 mL/100 g was administered to rats in the model group and the normal control group by gastrogavage, once daily for 30 successive days. After 30 days of medication all rats were sacrificed and their prostate tissues were extracted. The prostatic index was calculated. Pathological changes of rat prostate were observed under light microscope. Meanwhile, levels of IL-1β, IL-10, and TNF-α were detected using enzyme linked immunosorbent assay.
RESULTSCompared with the normal control group, the prostate index obviously decreased, levels of IL-1β, TNF-α, and IL-10 in the prostate tissue significantly increased in the model group (P < 0.01). Compared with the model group, the prostate index obviously decreased in high and medium dose QP groups, and the positive medicine group (P < 0.01); levels of IL-1β, TNF-α, and IL-10 obviously decreased in each QP group and the positive medicine group (P < 0.01). Compared with the positive medicine group, the TNF-α level decreased more obviously in the high dose QP group (P < 0.05). Compared with the normal control group, inflammatory reactions occurred obviously in rats' prostate of the model group. Compared with the model group, inflammatory reactions were milder in rats' prostate of each QP group and the positive medicine group, and their degrees were improved to some extent.
CONCLUSIONQP could treat CNP, which might be achieved by regulating local immune state of the prostate, relieving inflammatory reactions of the prostate, and lowering levels of IL-β, TNF-α, and IL-10 in the prostate tissue.

OBJECTIVETo report the clinical characteristics and treatment of 3 patients with juvenile xanthogranuloma (JXG).
METHODSA retrospective review of the medical records of 3 patients with JXG.
RESULTSJXG was characterized by solitary or multiple yellowish cutaneous nodules, or eye involvement . It could also affect pituitary. JXG was easily misdiagnosed as Langerhans cell histiocytosis (LCH). Treatment for JXG was surgical excision of a solitary skin lesion and some cases might be, spontaneous regression. In cases with multisystem involvement, chemotherapy regimens used to treat LCH may be effective.
CONCLUSIONSJXG is one of the more common non-Langerhans histiocytic proliferations and is frequently seen in infants and children. LCH-like chemotherapy is effective for patients with symptomatic multisystem JXG.

OBJECTIVETo investigate the clinical features, mutation of the GNAS1 and pathogenesis of progressive osseous heteroplasia (POH).
METHODThe typical clinical, pathological and radiographic features of a boy with POH were collected and summarized following family survey. The GNAS1 gene sequence of all family members were amplified by polymerase chain reaction (PCR) and the products were sequenced directly to identify the mutations. A literature review and long-term follow up were also conducted.
RESULTThe patient was an 11-year-old boy who had the onset in infancy, which indicates a chronic progressive cause of disease. The clinical features include the unsmooth local skin of the right shank where spread many rigid rice-like or irregular slabby uplifts, slabby bone-like sclerosis on the left lower mandible, left masticatory muscles, in lateral subcutaneous site of left hip joint and deep tissue, accompanied by gradually progressive difficulty in opening mouth. Histopathology showed that there were loosened hyperplasia of fibroblast and interstitial edema with punctiformed ossification. Radiographs showed flocculence hyperdense image in the subcutaneous tissues and muscles around left lower mandible, and the left masticatory muscles were obviously involved. The 3-dimensional computed tomography showed dislocations of the left temporomandibular joint. Sheeted hyperdense image with inequable density could be noted in lateral muscles of the left hip. And lamellar hyperdense image parallel to the long axis of the bone could be seen in the subcutaneous dorsum of the left foot and achilles tendon. Macro-thumb and of brachydactylia of the hands and feet were not present. The level of calcium, phosphorus and alkaline phosphatase in the blood were normal. Brother of same father but different mothers was free of the disease and no patient of the same disease was found in maternal line and paternal lines. A mutated allele in exon 7 and a polymorphism in exon 5 were found in GNAS1 gene in both of the patient and his father.
CONCLUSIONThere is possibility/likelihood/probability that Chinese children could develop POH. Translocated dermal ossification began in infancy and shows a progressive cause in childhood. The disease is characterized by the heterotopic ossification of the skin, deep tissue, muscles and facial surface tissues. The location of the mutation in this study was different from that reported in abroad studies although exist in the same exons.

OBJECTIVETo provide evidence for more accurate diagnosis of birth defects based on the pathoanatomy of congenital malformations.
METHODSData used in this study were obtained from Luliang City Hospital and three county hospitals of Shanxi province between February 2004 and March 2006. Autopsy and pathological examination of 160 dead fetuses and stillbirths were performed. Photos of dead fetuses and stillbirths were taken, tissues were cut into sections for pathological examination under microscope, all pathological information was recorded, and percentage of birth defects was calculated.
RESULTSThe proportion of dead fetuses and stillbirths with or without congenital malformations was 84.4% (135/160) and 15.6% (25/160), respectively. There were 16 categories of major external and internal birth defects in 135 cases of such defects. Congenital heart defects, anencephaly and spina bifida had a higher prevalence rate in the study period. The prevalence rate of non-malformation death and birth defects < 28 gestational weeks and internal anomalies > or = 28 gestational weeks was 14.61% (61/4175) and 17.25% (72/4175), respectively. A total of 413 in situ anomalies were found in 135 cases of autopsy. Spina bifida, anencephaly, congenital heart defects, aplasia or accessory lobe of lung, renal agenesis and dysplasis and congenital hydrocephaly were more closely associated with severe malformations than with mitis malformations. The cases of dead fetuses and stillbirths with multiple malformations (> or = 2 in situ anomalies) had a higher proportion (74.1%), whereas those with isolated malformations had a lower proportion (25.93%).
CONCLUSIONThe occurrence of congenital malformations in different embryonic developmental stages affects multiple organs. Postmortem examination of internal and multiple malformations of fetal deaths and stillbirths can provide more accurate diagnostic information for birth defects.

OBJECTIVETo study comparatively the cytotoxicity induced by acid bentonite and organic bentonite.
METHODSThe cytotoxicity of two kinds of bentonite was detected using CCK8 assay, neutral red uptake (NRU) assay, lactate dehydrogenase (LDH) leakage assay, apoptosis assay and hemolysis assay. In hemolysis assay human erythrocytes served as target cells and were exposed to the two kinds of bentonite at the doses of 0, 0.3125, 0.6250, 1.2500 and 2.5000 mg/ml for ten min. In other four assays, human B lymphoblast cells (HMy2.CIR) served as target cells and were exposed to the two kinds of bentonite at the doses of 0, 10, 20, 30, 60, 120 and 180 microg/ml for four h.
RESULTSIn hemolysis assay, the hemolysis rates induced by two kinds of bentonite at all doses were significantly higher than that of control (P<0.05); in CCK-8 assay, the cellular activities in acid bentonite group at the doses > or =30 microg/ml and in organic bentonite group at the doses > or =20 microg/ml were significantly lower than that of control (P<0.01); the similar results appeared in NRU assay and LDH assay, and the dose-effect relationship was observed in above 4 assays. In apoptosis assay, the early apoptosis cell rates in acid bentonite group at the dose of 180 microg/ml and in organic bentonite group at the doses of 120,180 microg/ml were significantly higher than that of control (P<0.05). Moreover, the results of five in vitro assays indicated the cytotoxicity induced by organic bentonite was higher than that induced by acid bentonite.
CONCLUSIONTwo kinds of bentonite could induce cytotoxicity, such as apoptosis and damage of cell membrane. The cytotoxicity of organic bentonite is higher than that of acid bentonite due to the different industrial treatment and characteristics of two kinds of bentonite particles.

OBJECTIVETo report a case of pulmonary surfactant protein (SP) gene mutation associated with pediatric interstitial lung disease, and study the clinical diagnosis process and review of related literature, to understand the relationship between interstitial lung disease and SP gene mutation in infants and children.
METHODThe clinical, radiological, histological, and genetic testing information of a case of SP gene mutation related pediatric interstitial lung disease were analyzed and related literature was reviewed.
RESULTA 2-year-old girl without a history of serious illness was hospitalized because of the shortness of breath, cough, excessive sputum, and the progressive dyspnea. Physical examination on admission revealed tachypnea, slight cyanosis, and the retraction signs were positive, respiratory rate of 60 times/minute, fine crackles could be heard through the lower lobe of both lungs; heart rate was 132 beats/minute. No other abnormalities were noted, no clubbing was found. Laboratory test results: pathologic examination was negative, multiple blood gas analysis suggested hypoxemia. Chest CT showed ground-glass like opacity, diffused patchy infiltration. Bronchoalveolar lavage fluid had a large number of neutrophils, and a few tissue cells. Eosinophil staining: negative. Fluconazole and methylprednisolone were given after admission, pulmonary symptoms and signs did not improve, reexamination showed no change in chest CT. Then lung biopsy was carried out through thoracoscopy. Histopathology suggested chronic interstitial pneumonia with fibrosis. The heterozygous mutation of R219W in the SFPTA1 and the S186N in SFTPC were identified by SP-related gene sequencing. The review of related literature showed that polymorphisms at the 219th amino acid in SP-A1 allele were found in adults with idiopathic pulmonary fibrosis (IPF), but there is no related literature in pediatric cases. The patient in this report had a mutation at the SP-A1 allele consistent with related literature. Data of 17 young children with mutation in SP-C gene showed that all the 17 cases had dyspnea and tachypnea, chest CT revealed diffuse opacities in lungs, the pathology of lungs was NSIP and CPI. There were 17 kinds of mutation and the common mutation was I73T. The mutation of S186N in SFTPC in our case has never been shown in previously published literature.
CONCLUSIONA case of interstitial lung disease with S186N gene mutation in SFTPC was preliminarily diagnosed in an infant. The SP-C gene mutations and polymorphisms are associated with pediatric interstitial lung disease.

BACKGROUNDDNA hypomethylation of long interspersed nuclear elements-1 (LINEs-1) occurs during carcinogenesis, whereas information addressing LINE-1 methylation in Wilms tumor (WT) is limited. The main purpose of our study was to quantify LINE-1 methylation levels and evaluate their relationship with relative telomere length (TL) in WT.
METHODSWe investigated LINE-1 methylation and relative TL using bisulfite-polymerase chain reaction (PCR) pyrosequencing and quantitative PCR, respectively, in 20 WT tissues, 10 normal kidney tissues and a WT cell line. Significant changes were analyzed by t-tests.
RESULTSLINE-1 methylation levels were significantly lower (P < 0.05) and relative TLs were significantly shorter (P < 0.05) in WT compared with normal kidney. There was a significant positive relationship between LINE-1 methylation and relative TL in WT (r = 0.671, P = 0.001). LINE-1 Methylation levels were significantly associated with global DNA methylation (r = 0.332, P < 0.01). In addition, relative TL was shortened and LINE-1 methylation was decreased in a WT cell line treated with the hypomethylating agent 5-aza-2'-deoxycytidine compared with untreated WT cell line.
CONCLUSIONThese results suggest that LINE-1 hypomethylation is common and may be linked to telomere shortening in WT.
