Clinical pharmacist in PIVAS should focus their ability on prescription checking and evaluation,medicine public-ity and education,communication with clinic.

OBJECTIVETo evaluate the effect of penile frenulum lengthening in the treatment of premature ejaculation (PE).

METHODSThirty-four males with PE were enrolled in this study, of whom 8 had received circumcision six months before and 4 had redundant prepuce, all with short frenulum. Those with a history of circumcision underwent reconstruction and lengthening of the frenulum, and those without received frenulum lengthening only.

RESULTSCompared with the baseline, the intravaginal ejaculation latency time (IELT) was significantly increased at 1 month after operation ([1.35 ± 0.49] vs [5.71 ± 2.69] min, t = -9.42, P <0.01), (1.42 ± 0.5) vs (5.31 ± 2.74) min in the patients without circumcision (t = -7.41, P <0.01), (1.12 ± 0.35) vs (7.00 ± 2.20) min in those with circumcision (t = -7.24, P <0.01), and (1.50 ± 0.58) vs (4.75 ± 1.71) min in those with redundant prepuce (t = -3.81, P <0.05). Totally, 94% of the patients were satisfied with their sexual intercourse postoperatively.

CONCLUSIONPenile frenulum plays an important role in penile erection. Reconstruction and/or lengthening of the frenulum can prolong penile erection and IELT in PE patients.

OBJECTIVETo investigate the clinical and pathological features, differential diagnosis of granulocytic sarcoma.

METHODSThe clinical manifestations, histopathological features, immunohistochemistry, treatment and prognosis were analyzed retrospectively in 10 cases of granulocytic sarcoma.

RESULTSThe age of patients ranged from 10 to 56 years (means = 35.8 years). The male-to-female ratio was 1.5:1. Histologically, the malignant cells of granulocytic sarcoma grew in a diffuse pattern. The cytoplasm was scanty, with eosinophilic fine granularity in some cells. The nuclei were round or focally irregular, and had finely dispersed chromatin. The mitotic figures were visible. Immunohistochemical stains for MPO, CD43, CD117, CD34 and CD99 were positive.

CONCLUSIONSGranulocytic sarcoma can occur in patients of all ages with a male predominance. The diagnosis of granulocytic sarcoma is assisted by the cytochemical stain for naphthol-ASD-chloroacetate esterase and/or immunophenotypic analyses for MPO, CD43, CD117, CD34, CD99. These stains aid in the distinction of granulocytic sarcoma from: lymphoblastic lymphoma, Burkitt lymphoma, diffuse large B-cell lymphoma, small round cell tumours, particularly in children, and blastic plasmacytoid dendritic cell neoplasm.

Objective To describe the clinical, neuroimaging and genetic profiles of amyotrophic lateral sclerosis with frontotemporal lobe degeneration ( ALS-FTLD).Methods From August 2011 to May 2015, patients with FTLD or other types of neurodegenerative dementia were physically examined in detail and electromyography was performed to those with suspected dysarthria, limb atrophy or weakness.Cognitive and behavioral screenings were performed to all ALS patients.Patients with ALS-FTLD entered further analysis of neuroimaging and genetics.Results Among the 8 patients diagnosed as ALS-FTLD, 4 patients began with personality change or amnesia, while diseases in the remaining 4 cases began with limb weakness or dysarthria.Dementia type of 7 cases was behavioral variant FTLD ( bvFTD) and 1 case was diagnosed as semantic dementia.Electromyography of all the 8 patients showed diffuse neurogenic changes.Constructional neuroimaging of 6 patients showed cerebral atrophy predominantly in frontal and temporal lobes.Fluorodeoxyglucose-positron emission tomography was conducted in 5 patients, indicating hypometabolism mainly in frontal and ( or) temporal lobes.NeuroQ analysis revealed that bilateral frontal lobes were the most hypometabolic areas for ALS-FTLD.Among 4 patients who underwent genetic screening, 1 patient was C9ORF72 mutation carrier.Conclusions bvFTD is the major type of dementia in the context of ALS.Metabolic neuroimaging could assist accurate diagnosis, and it reveals that bilateral frontal lobes are the most hypometabolic areas for ALS-FTLD.C9ORF72 gene mutation is an important pathogenic mutation for ALS-FTLD, although it is rare in Chinese population.

BACKGROUNDThere were only 3 multiple myeloma (MM) cell lines established in China. In this study, we succeeded in establishing a novel MM cell line and analyzed its biological characteristics.

METHODSMononuclear cells isolated from the peripheral blood (PB) and bone marrow (BM) of a patient with advanced MM (lambda light chain type) were cultured in medium. Cell morphology was analyzed by Wright-Giemsa-staining and cytochemical staining, immunophenotyping by flow cytometry and cytogenetic analysis by chromosome RHG-banding technique. Quantitative fluorescent polymerase chain reaction (PCR) was used to detect Epstein - Barr virus (EBV) DNA.

RESULTSThe established cell line could survive and proliferate in the presence of feeder cells or conditioned medium. The cells secreted lambda light chain and were negative for EBV. The Wright-Giemsa-staining showed typical plasmablast or plasma cell morphology. The cytochemical staining of the cells showed the following reactivity patterns: positive for acid phosphatase, negative for myeloperoxidase. The immunoprofile of the cells was concordant with that of MM cells: positive for CD10, CD28, CD38, CD138, CD56, CD49d, CD44, CD54 and CD58, negative for CD19, CD40, CD95, CD95L, CD34, CD2 and CD5. The cytogenetic analysis showed complex chromosome abnormality of i (1q+), 8q+, 13q+, i (17q), i (18q) and +M. There was no difference in morphology, immunophenotype and cytogenetics between cells from PB and BM.

CONCLUSIONSAn MM cell line secreting lambda light chain named CZ-1 was established. The cells from both PB and BM have the same biological characteristics.

OBJECTIVETo compare the levels of STAT4 tyrosine phosphorylation in peripheral T-lymphocytes induced by IL-12 in rheumatoid arthritis (RA) and osteoarthritis (OA).

METHODSFrom May 2007 to August 2009, peripheral blood mononuclear cells (PBMCs) were isolated from RA patients [RA group, all the cases were female, the age was from 28 to 55 years with an average of (45.0 +/- 13.0) years] and OA patients [OA group, all the cases also were female; the age was from 55 to 75 years with an average of (67.0 +/- 9.6) years]. The purity of T-lymphocytes from PBMCs was accredited by flow cytometry. The IL-12 of 50 ng/ml added in T-lymphocytes, the levels of STAT4 tyrosine phosphorylation were detected by western blot after different time intervals (0, 10, 30, 60 min).

RESULTSThe purity of T-lymphocytes were above 91% through diremption and depuration for peripheral blood monouclear cells. The levels of STAT4 tyrosine phosphorylation in T-lymphocytes from RA induced by IL-12 were higher than that from OA in the different times (10, 30, 60 min); after 30 min, its levels from RA and OA achieved to crest value.

CONCLUSIONSTAT4 in peripheral T-lymphocytes of rheumatoid arthritis was more easily to be activated than osteoarthritis.
