Objective To assess the efficacy of a long-pulsed 1064 nm Nd :YAG laser system in treating pediatric cutaneous hemangiomas. Methods 207 patients (20 days-10 years old,164 cases in pro-liferative phase and 43 in stationary phase) with cutaneous hemangiomas were divided into 2 groups ac-cording lesions. Group A contained 142 patients with lesions located in skin completely. Group B con-tained 65 patients, in which the lesions involved in subcutaneous portion. All patients were treated with single pulse shots by a long-pulsed 1 064 nm Nd :YAG laser, with 2 mm and 6 mm spot size in diameter, and with related energies from 50 to 90 J/cm~2 and pulse lengths of 10, 40 and 60 ms, respectively. All treatments were given at 1-month interval. Results After 1-6 times of treatment, there was no statistic significance of effective rate between group A and group B. Both general effective rates were 100%. The rate of side effects was 11.6 %, all of which recovered gradually. Conclusions The long-pulsed 1064 nm Nd : YAG laser offers efficient treatment of pediatric superficial cutaneous hemangiomas and side effects are minimal and transient.

OBJECTIVE Xingnaojing injection(XNJ)is an extracts of Angong Niuhuang Pill that is a well-known traditional Chinese medicine used for the treatment of septicemia and stroke.This study aims to investigate the effect of XNJ on intestinal mucosal barrier in septicemia and intracerebral hem-orrhage(ICH)mice models.METHODS The septicemia mice models were induced by intravenous in-jection with lipopolysaccharide(20 mg·kg-1).And the ICH mice models were made by intrastriatal injec-tion of bacterial collagenase. The septicemia animals were treated intravenously with XNJ at dose of 2.5,5,10,or 15 mL·kg-1.The ICH animals were treated intravenously with XNJ at dose of 10 mL·kg-1. Thereafter, the permeability of intestinal mucosa was assayed by FITC-D method. RESULTS Com-pared with the control group(44.72±4.30),the permeability of intestinal mucosa in the mice in septice-mia group (233.68±28.18) was significantly increased (P<0.01). Treatment with XNJ at dose of 5, 10, and 15 mL·kg-1reduced the permeability of intestinal mucosa (150.45 ± 17.52,139.21 ± 17.05,132.55 ± 18.88,respectively, P<0.01)except 2.5mL·kg-1(240.71±21.42,P>0.01);Compared with sham group (57.88±7.31),the permeability of intestinal mucosa in the mice of ICH(282.25±23.78)was significantly in-creased(P<0.01). Treatment with XNJ (10 mL·kg-1)in the mice of ICH group ameliorated the change of permeability in intestinal mucosa (148.83±15.86, P<0.01). CONCLUSION XNJ exhibits the protec-tive effect on the intestinal mucosal barrier in septicemia and ICH, which will prevent the endotoxin to penetrate the intestinal mucosa and then to enter the circulation in infections and stress.

Objective To investigate the method of directed differentiation dendritic cells from embryonic stem cells(ESC) and to amplify high purity DCS in vitro for immunity therapy.Methods E14 ESC line were generated ESC-derived dendritic cells(ES-DC) in complete medium further supplemented with granulocyte-macrophage colony-stimulating factor(GM-CSF) and interleukin-3(IL-3).ES-DCs was used flow cytometry to determine CD11c,CD80,CD86,MHC-Ⅱ cell surface phenotype. Lipopolysaccharide (LPS) were added to induce the ES-DCs matured. The matured ES-DCs was harvested 24 hours later to be identified with morphology, transmission electron microscopy, analyzed by flow cytometry and compared with the immatured ES-DCs phenotype. The antigen presenting was evaluated by mixed lymphocyte responses.Results The ES-DC had obviously dendritic processes under scanning electron microscope . The immature DCs express low level of CD11c(4.33±0.23)%,CD80 (7.62±0.19) %, CD86 (4.77±1.22) % and MHC-Ⅱ (9.68±0.15) %, but the mature DCs express higher lerve of CD11c(47.36±2.68)%,CD80 (74.4±1.47) %, CD86 (29.77±2.00) % and MHC-Ⅱ (87.56±2.75) %. MLR showed that ES-DCs could effectively stimulate lymphocyte to proliferate.Conclusion These results provide evidence that DCs can be generated from E14 ESC with GM-CSF and IL-3, express high level of CD11c,CD80, CD86, MHC-Ⅱ and can effectively stimulate lymphocyte to proliferate. ES cells may become new origin for DCs which provided the immunotherapy.

According to morphological and microscopic characteristics, a high-efficient decolorizing fungus, the strain Asaw117, was identified as Aspergillus awamori. Selecting eight different dyes from Azo dyes, anthraquinones dyes and oxygen Quinones dyes, the decolorizing assays of various dyes showed that the strain Asaw 117 was the highest decolorizing potential to 0.1 g/L Vat Blue RSN, the discoloration rate up to 100 percent. Comparing to different kinds of medium and several of carbon and nitrogen sources, the strain had the best decolorizing efficient although grew slower in the Czapek medium, otherwise, grew quicker and decolorizing efficient lower in the PDF medium. It could use Vat Blue RSN as a nitrogen source, but not as a carbon source. The medium composing of saccharose and ammonium nitrate as carbon and nitrogen sources was decolorizing potential markedly during different combinations of carbon and nitrogen sources. So the strain has good potential for the dyeing wastewater treatment

OBJECTIVETo analyze the parameters of urodynamic tests for patients with type-III B prostatitis and evaluate the significance of the results of urodynamic tests in the choice of therapies for this disease.
METHODSUrodynamic tests were performed for 87 type-III B prostatitis patients aged 22-45 (30.7 ± 8.5) years, who had moderate or severe lower urinary tract symptoms (LUTS) and failed to respond to routine therapy. Different treatments were administered according to the results of urodynamic tests followed by observation of the therapeutic effects.
RESULTSUrodynamic abnormalities were found in 70 of the 87 patients, bladder outlet obstruction in 28 (32.2%), detrusor overactivity in 25 (28.7%), bladder hyperesthesia in 18 (20.7%), low compliance in 10 (11.5%), detrusor-external urethral sphincter dyssynergia in 1 (1.1%), and impaired detrusor contractile function in 1 (1.1%). Treatments achieved obvious effectiveness in 26 cases (29.9%), effectiveness in 51 (58.6%), and no effectiveness in 10 (11.5%).
CONCLUSIONUrodynamic tests contribute significantly to the choice of therapies for type-III B prostatitis patients with moderate or severe LUTS.

Objective To explore the effect of 1a,25(OH)2 D3 on circadian clock gene expressions in cardiac myocytes.Methods Cultured cardiac myocytes isolated from 7 -day -old Sprague -Dawley(SD)rats were identified by immunofluorescence.The medium including 1a,25 (OH)2 D3 (final concentrations were 0 nmol/L,1 nmol/L, 10 nmol/L,50 nmol/L and 100 nmol/L)were added to primary myocardial cells to culture for 2 h and then total RNA was extracted.Real -time polymerase chain reaction (RT -PCR)was applied to analyze myocardial cells circadian clock gene (Bmal1,Per2,Rev -erba)transcript levels to determine optimum concentration of 1a,25(OH)2 D3 .Then, the primary myocardial cells cultured for 72 h were divided into 3 groups:the control group was of serum -free culture medium;serum shock group was of DMEMcontaining 50%volume fraction of horse serum cultured 2 h;1a,25(OH)2 D3 treatment group receiving 1a,25 (OH)2 D3 at optimal concentration cultured 2 h.The cells were collected at 7 time points (0 h,4 h,8 h,12 h,16 h,20 h,24 h)and then total RNA was extracted.RT -PCR was applied to analyze circa-dian clock gene (Bmal1,Per2,Rev -erba)transcript levels in the myocardial cells.Results In the presence of 50 nmol/L 1 a,25(OH)2 D3 ,the Bmal1 mRNA expression showed the highest level,but the Per2 and Rev -erba mRNA expression levels were minimum.Compared with the control group,both 1a,25 (OH)2 D3 treatment group and serum shock group caused day -cycle rhythmic oscillation in circadian clock genes(Bmal1,Per2,Rev -erba)in the cardiac myocytes.And the expressions pattern of Bmal1 and Per2 genes were in the opposite phase.While Bmal1 gene expres-sion appeared at peak at 12 h,Per2 gene expression appeared in a trough.Expression of Rev -erba gene trend began to rise at 8 h,and the highest expression level appeared at 12 -16 h.Conclusions 1a,25(OH)2 D3 can affect Bmal1, Per2 and Rev -erba mRNA expressions of circadian clock genes in the cardiac myocytes.

The changes of interstitial cells of Cajal(ICC)distribution and connexin 43(Cx43)expression in gastric muscle layers were assayed in gastroparesis models of streptozotocin-induced diabetic rats.The results showed that gastric emptying was significantly delayed,the contraction frequency and amplitude of gastric muscle segments were greatly decreased,Cx43 gray values were significantly increased and Cx43 distributed homogeneously with ICC immunopositivity in the model rats.These changes appear to be related to the pathogenesis of diabetic gastroparesis.
