OBJECTIVETo study the clinicopathologic features of dendritic fibromyxolipoma for the purpose of differentiating it from other confusable soft tissue neoplasms.

METHODSEight cases of dendritic fibromyxolipoma were obtained and their clinicopathologic features were studied. Immunohistochemistry stains for CD34, bcl-2, vimentin, cytokeratin, EMA, S-100, HHF35 and smooth muscle actin were performed with labeled streptavidin-biotin (SLAB) system on DAKO auto-immunohistochemical stainer.

RESULTSDendritic fibromyxolipoma usually occurrs in middle-aged to elderly men, developing primarily in the subcutis or muscular fascia of the head and neck region, shoulder, back, calf and foot. Grossly, it is well-circumscribed, partly thinly encapsulated lesion with focal mucinous or gelatinous cutting surface. Histologically, all these tumors showed similar histological features., and were characterized by an admixture of mature adipose tissue, spindle and stellate cells, and abundant myxoid stroma with prominent collagenization. The proportion of above elements varied in different tumors or in different areas within the same tumor. One of the pathologic characteristics was the proliferation of spindle cells and stellate cells showing thin cytoplasmic dendritic prolongations. No cytological atypia or mitotic activity could be identified. Furthermore, the lesions were well-vascularized and the vascular elements consisted of small to median-sized and capillary-sized plexiform vessels. Spindle cells were strongly positive for CD34, bcl-2 and vimentin but negative for S-100 protein and epithelial and muscle markers.

CONCLUSIONSDendritic fibromyxolipoma is characterized by clinicopathologic and immunohistochemical features. Based on those features of this tumor, this entity appears to represent a transitional form between spindle cell lipoma and solitary fibrous tumor, and should be distinguished from myxiod liposarcoma and myxoid malignant fibrous histiocytoma. Due to the benign nature of this lesion, simple local excision is curative.

OBJECTIVE: To explore the relationship between chromosome anomaly and spontaneous abortion, and to provide useful information for genetic counseling and prenatal diagnosis in reproductive clinic. METHODS: A total of 1 780 patients who had a history of spontaneous abortion before 24 weeks of gestation were enrolled. The lymphocyte culture and harvest were performed according to standard methods. Karyotypes were analyzed by G-banding in all cases and C- banding in some cases in addition. RESULTS: Altogether 57 abnormal karyotypes were found and the overall incidence of chromosomal abnormalities was 3.20% (women 3.32%; men 2.12%). Among them 23 cases were the balanced translocation; 14 cases were the Robertsonian translocation, 3 cases were the complex chromosomal rearrangement, and the other 17 cases were the other abnormalities. In women with 1, 2, 3 or more spontaneous abortion, the incidence of chromosomal abnormalities was 1.7%, 2.3%, and 5.8%, respectively. CONCLUSION Translocations are the major abnormal karyotpes associated with spontaneous abortions. The chance of finding chromosomal aberration increases with the number of abortions. Chromosomal abnormalities are more common in women with 3 or more spontaneous abortions.

Objective To investigate the prevalence change of drinking water type of endemic fluorosis and the effect of control measures implemented in Huangyuan county of Qinghai province. Methods In 2009, all the endemic fluorosis villages in Huangyuan county were divided into two degrees, light and medium, according to the water fluorosis content before implementing the improving water project, 1 to 2 villages were selected from each degree village, respectively,as monitoring sites, and a total of 3 villages were selected. Source water and tap water samples were collected from each village and water fluoride concentration was determined. Dental fluorosis of all children aged 8 to 12 of monitoring villages was examined, and urine samples were collected by age group of children for determination of urinary fluoride. Clinical skeletal fluorosis of adults over 16 years of age was examined, and 20 copies of adults urine samples were collected to determine urinary fluoride. One village was selected in the 3 villages monitored to conduct X-rays examination of skeletal fluorosis. Water fluoride was tested in accordance with the "Non-metallic Targets Test Methods for Drinking Water" (GB/T 5750.6-2006); urinary fluoride was tested by fluoride ion-selective electrode method (WS/T 89-1996); dental fluorosis was diagnosed using Dean method;adult skeletal fluorosis was diagnosed by "Clinical Diagnostic Criteria for Endemic Skeletal Fluorosis"(WS 192-2008). Results Twelve water samples were assayed, water fluoride was (0.35 ± 0.43) mg/L. The detectable rate of dental fluorosis of 122 children aged 8-12 was 34.43%(42/122) and the geometric mean urinary fluoride was 0.89 mg/L of the 96 children. Of the 834 adults aged 16 and over, clinical detection of skeletal fluorosis was 47.72% (398/836) and geometric mean urinary fluoride was 1.10 mg/L of the 65 cases of adult urine samples assayed, detection rate of X-rays was 31.4% (11/35) in Gangou village of the 35 adults examined.Conclusions In Huangyuan county, water fluoride of the 3 surveyed villages are normal but the endemic fluorosis is still serious. It should strengthen monitoring and analyze the causes and improve prevention measures.

ObjectiveTo investigate the development trend of drinking water type of endemic fluorosis in Qinghai province, and to provide the basis for the prevention and treatment of the disease. MethodsIn 2009, six monitoring counties were chosen by using simple random sampling methods, all diseased villages of the six monitoring counties were classified into light, moderate and severe disease types according to water fluorine content on the historical data, and 1 village was respectively chosen from each type. In monitoring villages with improved water, 3 tap water and one source water samples were collected, respectively. Five water samples were collected randomly in water unimproved monitoring villages according to water well locations of east, west, south, north and center. The fluorine content in water and urine was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006). Children aged 8 to 12 were examined for dental fluorosis by Dean method.Clinical osteofluorosis of all the resident over the age of 16 was examined, 2 village of these counties were randomly selected, and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray using Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008). Urine sample of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method (WS/T 89-2006).

The crude extracts of the fermentation broth from a marine sediment-derived actinomycete strain, Saccharothrix sp. 10-10, showed significant antibacterial activities against drug-resistant pathogens. A genome-mining PCR-based experiment targeting the genes encoding key enzymes involved in the biosynthesis of secondary metabolites indicated that the strain 10-10 showed the potential to produce tetracenomycin-like compounds. Further chemical investigation of the cultures of this strain led to the identification of two antibiotics, including a tetracenomycin (Tcm) analogs, Tcm X (1), and a tomaymycin derivative, oxotomaymycin (2). Their structures were identified by spectroscopic data analysis, including UV, 1D-NMR, 2D-NMR and MS spectra. Tcm X (1) showed moderate antibacterial activities against a number of drug-resistant pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) pathogens, with the MIC values in the range of 32-64 microg x mL(-1). In addition, 1 also displayed significant cytotoxic activities against human cancer cell lines, including HL60 (leukemia), HepG2 (liver), and MCF-7 (breast) with the IC 50 values of 5.1, 9.7 and 18.0 micromol x L(-1), respectively. Guided by the PCR-based gene sequence analysis, Tcm X (1) and oxotomaymycin (2) were identified from the genus of Saccharothrix and their 13C NMR data were correctly assigned on the basis of 2D NMR spectroscopic data analysis for the first time.

PURPOSE: OnabotulinumtoxinA (BoNT-A) is a promising therapy for treating neurogenic detrusor overactivity (NDO) in individuals with spinal cord injury (SCI). This systematic review and meta-analysis aimed to carry out an in-depth review and to make an objective estimation of the efficacy and safety of BoNT-A on NDO after SCI. METHODS: The PubMed, Embase, and Cochrane databases were searched for all relevant articles published from 2001 to 2016 that referred to NDO, SCI, and BoNT-A or botulinum toxin A. All data were recorded in an Excel spreadsheet by 2 individual reviewers. Review Manager version 5.3 was used to carry out the meta-analysis. RESULTS: This analysis included 17 studies involving 1,455 patients. Compared with placebo and baseline, BoNT-A was effective in increasing maximum cystometric capacity, volume at first involuntary detrusor contraction, cystometric bladder capacity (all P < 0.00001), compliance (P=0.001), and the number of patients with complete dryness (P=0.0003), and decreasing detrusor pressure, the number of patients with no involuntary detrusor contractions, the maximum flow rate, the incidence of detrusor overactivity (all P < 0.00001), and the number of urinary incontinence episodes (P=0.001). There were no statistically significant differences between doses of 200 U and 300 U or between injections into the detrusor and submucosa. There were no life-threatening adverse events. CONCLUSIONS: BoNT-A is effective and safe in treating NDO after SCI. There were no statistically significant differences between doses of 200 U and 300 U or between injecting into the detrusor and submucosa. However, more high-quality randomized controlled trials are still needed.

OBJECTIVETo screen and analyze CD34(+) cell specific microRNAs (miRNAs) from the patients with acute myelogenous leukemia (AML) and their expression.

METHODSCD34(+) cells were sorted from AML patients or the mobilized peripheral blood of the donors of hematopoietic stem cell transplantation (normal control subjects) and followed by the extraction of the cell total RNAs. The differentially expressed microRNAs (miRNAs, miR) were selected after hybridizing with miRNA microarray, real time polymerase chain reaction (real-time PCR) was subsequently applied to confirm the expression of the selected miRs, and PCR products were further cloned and sequenced to check their specificity.

RESULTSOf the differentially expressed miRNAs, 191 were found to be at least one-fold change in the CD34(+) cells between the AML patients and the normal control subjects. Of the 191 miRNAs, the expression difference of 94 was significant (P < 0.05). Among these 94 miRNAs, the expression of 44 miRNAs was increased and the other 50 miRNAs was decreased in the CD34(+) cells from the bone marrow of AML patients compared with the CD34(+) cells from the mobilized peripheral blood of the normal control subjects. Real time PCR verified that the expression level of miR-10a and miR-220c in the CD34(+) cells from the bone marrow of AML patients was 19.6% and 19.0% of that of CD34(+) cells from mobilized peripheral blood of the normal control subjects. DNA sequencing and BLAST DNA database searching results indicated that the PCR products were really miR-10a and miR-220c.

CONCLUSIONA variety of differentially expressed-miRNAs are existed between AML and normal control subjects CD34(+) cells, the expression of miR-10a and miR-220c was significantly down-regulated in the CD34(+) cells from the bone marrow of AML patients.
