OBJECTIVETo evaluate the clinical effect and safety of dapoxetine in the treatment of premature ejaculation (PE).
METHODSWe randomly assigned 116 PE patients to receive dapoxetine on demand at 30 mg qd (dapoxetine group, n = 60, aged 23-49 years) or oral tamsulosin at 20 mg qd (control group, n = 56, aged 24-46 years). After 4 weeks of medication, we compared the clinical global impression of change (CGIC) , PE profile (PEP) scores, intravaginal ejaculation latency time (IELT) , and adverse reactions between the two groups of patients.
RESULTSCompared with the baseline, the IELT was remarkably prolonged after treatment both in the dapoxetine group ([0.86 ± 0.17] vs [4.32 ± 2.23] min, P < 0.05) and the control ([0.88 ± 0.15] vs [4.17 ± 2.26] min, P < 0.05), with no statistically significant difference between the two groups (P > 0. 05). The post-treatment rate of CGIC in the dapoxetine group had no statistically significant difference from that in the control (85.00% vs 82.14%, P > 0.05). In comparison with pre-treatment, the patients of both the dapoxetine and control groups showed dramatically improved scores after medication in perceived control over ejaculation (0.85 ± 0.23 vs 2.13 ± 0.97 and 0.88 ± 0.21 vs 2.06 ± 0.34, both P < 0.05), ejaculation-related personal distress (1.15 ± 0.64 vs 2.89 ± 0.26 and 1.19 ± 0.53 vs 2.82 ± 0.69, both P < 0.05), satisfaction with sexual intercourse (0.81 ± 0.33 vs 2.58 ± 0.37 and 0.79 ± 0.28 vs 2.45 ± 0.32, both P < 0.05), and ejaculation-related interpersonal difficulty (2.05 ± 0.61 vs 3.24 ± 0.35 and 2.03 ± 0.65 vs 3.18 ± 0.76, both P < 0.05), with no significant differences between the two groups (P > 0.05). The incidence of adverse reactions was significantly lower in the dapoxetine than in the control group (3.33% vs 30.36%, P < 0.05).
CONCLUSIONDapoxetine is effective for the treatment of PE, with its advantages of prolonging the intravaginal ejaculation latency time, improving the quality of sexual life, and low incidence of adverse reactions.

To explore the clinical and pathological characteristics of hepatosplenic gammadelta T-cell lymphoma and its relationship with Epstein-Barr virus infection, the clinical features of a 9-year-old girl with hepatosplenic gammadelta T-cell lymphoma were investigated, the smears of bone marrow was stained with Wright' s stain, biopsies of bone marrow and liver specimen were embedded in plastic and sliced about 4 microm in thickness and routinely stained with HE staining, the immunohistochemical staining was used to mark the tumor cells, and EBER probes were used to detect Epstein-Barr virus RNA. The results showed that the girl presented with prolonged fever, anemia, thrombocytopenia, hepatosplenomegaly, chronic active Epstein-Barr virus infection, and elevated levels of serum ferritin and lactate dehydrogenase. Bone marrow aspirate revealed the infiltration of atypical lymphocytes in the bone marrow stroma. The liver biopsy specimen revealed the infiltration of lymphocytes in the sinusoids, which was positive for the T-cell associated marker CD3 and activated cytotoxicity-associated marker granzyme B. In-situ hybridization analysis with EBER probes revealed that the above-mentioned characteristics were negative in neoplastic cells. It is concluded that hepatosplenic gammadelta T-cell lymphoma is a disease with distinctive clinical, histopathologic, and phenotypic characteristics. Hepatic and/or splenic and/or bone marrow biopsy with combined phenotype is beneficial to diagnosis. Epstein-Barr virus infection is late event involving an already transformed gammadelta T-cell clone.

OBJECTIVETo study the clinical response to comprehensive therapy in children with rhabdomyosarcoma.
METHODSClinical data of 13 children (8 males and 5 females) with rhabdomyosarcoma from January 1998 through October 2005 were retrospectively studied. Their ages ranged from 7 months to 12 years. The 13 cases of rhabdomyosarcoma consisted of 2 cases in stage I, 2 cases in stage II, 3 cases in stage III, and 6 cases in stage IV. Rhabdomyosarcoma was confirmed by biopsy, 12 cases (92.3%) presenting as embryonal type and 1 as alveolar type in histology. One patient underwent surgery treatment alone, one patient received surgery plus local radiation treatment, one patient received surgery plus chemotherapy and 10 patients were administered with a combination of surgery, local radiation treatment and chemotherapy. The chemotherapy protocol before 2002 was VDCA, VAC or VadrC. After 2002, the COG protocol was employed, with CDV+IE for stage III, and CT+VAC or CT+VAC+VCT for stage IV patients.
RESULTSThe 2-year overall survival was 60% in the 10 patients who received a combination of surgery, local radiation treatment and chemotherapy, but the three patients died without receiving combination therapy. The 2-year overall survival in the 13 patients was 46.2%. The 2-year overall survival of the patients after 2002 (60%, 3/5) was higher than that before 2002 (37.5%, 3/8).
CONCLUSIONSEmbryonal rhabdomyosarcoma dominates the histology type in children, which is highly malignant. A combination therapy of surgery, local radiation and chemotherapy can result in a satisfactory therapeutic effect in children with rhabdomyosarcoma.

Objective To construct the adeno-associated virus (AAV)vector of mouse carrying T-bet gene,which was applied to mouse model of asthma by nose,and to investigate the immunomodulatory effects of T-bet delivery on asthma.Methods Forty healthy Balb/c mice (aged 6-8 weeks) were randomly divided into 4 groups:control group (group A),asthma model group(group B),model/control recombinant adeno-associated virus carrying enhanced green fluorescent protein(rAAV-eGFP) intervention group (group C) and model/rAAV-T-bet virus intervention group(group D),with 10 mice in each group.In group B,group C,and group D,Balb/c mice were sensitized by intraperitoneal injection with OVA and challenged by nebulized OVA.In group C and group D,Balb/c mice were intervened with the isodose rAAV-eGFP and rAAV-T-bet,while in group B,the mice were intervened with the same amount of saline,both of them were dropped into the nasal cavity.Twenty-four hours after the last injection,the mice were sacrificed and the samples were obtained.The total cells in bronchoalveolar lavage fluid (BALF) were counted,and the types of cells were analyzed by Wright-Giemsa staining.The levels of interferon-γ (IFN-γ),IL-4 and IL-5 in BALF were determined by enzyme-linked immunosorbent assay.The expressions of T-bet,GATA-3 and Foxp3 protein in the lungs of asthmatic mice were detected with immunohistochemical technique.Results 1.The level of specific transcription factor T-bet in group B and group C were distinctly lower than that of group A (all P < 0.05),while the level of GATA-3 was significantly higher than that of group A(all P < 0.05).In group D,the expression of T-bet protein was stronger than that in group B and group C,however,the expression of GATA-3 decreased obviously (all P < 0.05).The results of Foxp3 were similar to T-bet.2.In group D,the mice had suppressed levels of IL-4 [(158 ± 55) ng/L] and IL-5 [(68-± 22) ng/L] compared with those in group B and group C(all P <0.05).The level of IFN-γ[(113-±35) ng/L] increased compared with those in group B and group C (all P < 0.05).At the same time,the number of total cells and eosinophil in BALF were both obviously lower than those of group B and group C (all P < 0.05).Conclusions On the basis of building mouse model of asthma,intranasal administration of rAAV-T-bet can deliver T-bet gene to airway successfully and efficiently,and plays an immunomodulatory role in immune confusion of asthma.

The purpose of this study was to evaluate the safety of cryopreserved and thawed peripheral blood stem cell (PBSC) fractionated return infusions in children. 35 children patients with malignant tumors (13 acute leukaemias, 15 neuroblastomas and 7 malignant lymphomas) received fractionated return infusions of cryopreserved stem cells after undergoing high-dose chemotherapy without or with total body irradiation. The toxicities of 70 return infusions were evaluated. All patients were mobilized by chemotherapy plus recombination human granulocyte colony-stimulating factor (rhG-CSF), and then PBSCs were collected by a separator CS-3000 plus or COBE spectra-4. The grafts were cryopreserved in 10% dimethyl sulfoxide (DMSD) and stored in liquid nitrogen. There were totally 70 PBSC transfusions. The total volume of PBSCs transfused: 190 - 420 ml (265 +/- 73 ml or 13.7 +/- 4.2 ml/kg) with a mean of (4.43 +/- 1.91) x 10(8)/kg of PBSCs, and 0.94 +/- 0.18 g/kg of DMSO. The single dose: 90 - 300 ml (132 +/- 37 ml or 6.6 +/- 5.2 ml/kg) with a mean of 0.68 +/- 0.12 g/kg of DMSO. Symptoms occurring during the infusions were recorded. All patients were monitored for 24 hours after infusion. Pulse, blood pressure, body temperature, and respiratory rate were recorded every 15 minutes. At four hours before and 8 hours after infusion, urinalysis was performed. Serum potassium, sodium, creatinine, total bilirubin, aspartate amino transferase (AST), and alanine amino transferase (ALT) levels were examined within 24 hours before and after the first infusion. The results showed that the toxicities observed included hemoglobinuria in 54 return infusions (77.1%), headache in 28 (40.0%), nausea in 24 (34.3%), vomiting in 17 (24.3%), and abdominal pain in 8 (11.4%). Patients who received a graft > 200 ml tended to have a higher frequency of hemoglobinuria, headache, nausea, vomiting, or abdominal pain (P<0.01), and they disappeared quickly, too. Total bilirubin increased after the first return infusion (P<0.01), and there was a significant correlation between the volume of infusion and the degree of total bilirubin increase (r=0.8977, P<0.01). No renal failure or shock occurred. It is concluded that transient hemoglobinuria, headache, nausea, vomiting, and abdominal pain are common toxicities associated with PBSC autograft, and these toxicities are related with a single volume of PBSCs transfused. Total bilirubin increase is correlated with the volume of infusion. In a word, the toxicity is less frequent and lower severe in children with fractionated infusions of cryopreserved peripheral blood stem cell.

OBJECTIVETo study the antifungal treatment and intensive chemotherapy in children with acute leukemia and invasive aspergillosis.
METHODSThe diagnosis and treatment of 4 cases of childhood acute leukemia complicated by invasive aspergillosis between July 2007 and July 2008 were studied retrospectively.
RESULTSThree children who underwent remission induction chemotherapy for ALL and one who underwent consolidation chemotherapy for AML developed invasive aspergillosis. One child with proven aspergillosis and 3 with possible aspergillosis all had halo sign on CT at diagnosis. Voriconazole or amphotericin B was given as primary therapy. Improvements of fungal lesions were shown by CT after two to four weeks of antifungal therapy. Complete radiologic remissions were achieved between 4 months and one year. The intensive chemotherapy schedule was continued in all of 4 cases. The median time from fungal infection to the continuation of chemotherapy was 35 days. None showed recurrence of fungal infection.
CONCLUSIONSThe halo sign on CT may be a reliable indicator for the early diagnosis of invasive aspergillosis. The preemptive antifungal therapy on the basis of the identification of a halo sign and the reversal of immunosuppression may improve the outcome of invasive aspergillosis. Prolonged antifungal treatment during subsequent cycles of chemotherapy permits completion of scheduled intensive chemotherapy without fungal recurrence.

OBJECTIVETo evaluate the effects and the toxicity of the protocol of CDV combined with CiE as pre-operative chemotherapy in childhood stage IV neuroblastoma.
METHODSThe clinical data of 27 children aged from 1.2 to 8 years with neuroblastoma in stage IV was retrospectively studied. The primary sites of the diseases were abdomen (n = 21), posterior mediastinum (n = 4) and pelvic cavity (n = 2). Twenty three patients had bone marrow metastasis. Twelve patients had bone metastasis. All patients were treated with the CDV protocol (cyclophosphamide + doxorubicin + vincristine) for 3 cycles and the CiE protocol (cisplatin + etoposide) for 2 cycles. Neuroblastoma therapeutic response evaluation criterion and common terminology criteria for adverse events of National Cancer Institute were used to evaluate effects and chemotherapy related toxicity.
RESULTSAll patients received the pre-operative chemotherapy. The overall response rate was 82%. After chemotherapy, 24 patients received operations. Total resection of primary tumor was found in 14 patients (58%) and part resection in 10 patients (42%). The most common chemotherapy related toxicity was bone marrow suppression: grade IV suppression of neutrophils (n = 27), reduction in hemoglobin (III grade, n = 7; IV grade, n = 20) and reduction in platelet (III grade, n = 2; IV grade, n = 25). Infection was found in all patients and was controlled with antibiotics. I or II grade lesions of digestive, liver and kidney were found and could be recovered after therapy. Grade I neurotoxicity occurred in 2 patients (7%). The heart function damage was not found in any of patients.
CONCLUSIONSThe protocol of CDV combined with CiE as pre-operative chemotherapy might be effective in children with stage IV neuroblastoma.
