Objective To compare the clinical efficacy and adverse effects of photodynamic therapy (PDT) versus pulsed dye laser(PDL)for the treatment of port wine stains(PWS). Methods Forty?five patients with PWS were enrolled in this study. The PWS lesions in each patient were randomly divided into PDT and PDL areas. Hematoporphyrin monomethyl ether of 5 mg/kg was injected intravenously into the PDT area protected from light, followed by 20?minute irradiation with a 532?nm, solid?state, continuous?wave laser(power density:80-100 mw/cm2;spot diameter: 7 cm)10 minutes later. The PDL area was treated with a single session of 595?nm pulsed dye laser radiation(spot diameter:7 mm;pulse width:10 ms;energy density:10-12 J/cm2). The interval between PDT and PDL treatment was no shorter than two months. Follow up visits were scheduled on day 4 and week 8 after each treatment. Adverse reactions were recorded, and photographs were taken before and 8 weeks after the treatment for evaluation of lesion regression. Results In the case of PDT area, 10 cases(22.22%)were nearly cured, 22(48.89%)achieved marked improvement, 9(20.00%)improvement, 4(8.89%)no improvement. As far as the PDL area is concerned, 6 cases(13.33%)were nearly cured, 16(35.56%)achieved marked improvement, 18(40.00%)improvement, and 5 (11.11%)no improvement. The response rate was significantly higher in the PDT area than in the PDL area(Z=2.48, P<0.05). Hyperpigmentation, which spontaneously subsided within 3 to 6 months, was the main adverse reaction. No significant difference was found in the incidence rate of adverse reactions between the PDL and PDT areas(24.44%vs. 15.56%, Z=1.26, P>0.05). Conclusion For the treatment of PWS, both PDT and PDL are effective and safe, and single?session PDT appears to be superior to single?session PDL.

Objective To investigate the effect of penehyclidine hydrochloride ( PHC) pretreat?ment on nuclear factor erythroid 2?related factor 2∕heme oxygenase?1 ( Nrf2∕HO?1) signaling pathway in re?nal tissues of rats with rhabdomyolysis?induced acute kidney injury ( AKI) . Methods Thirty?six pathogen?free male Sprague?Dawley rats, weighing 200-220 g, were assigned into 3 groups ( n=12 each) using a random number table: control group (group C), group AKI and PHC pretreatment group (group PHC). Rhabdomyolysis was induced by intramuscular injection of 50% glycerol 10 ml∕kg in bilateral hindlimbs. PHC 0?2 mg∕kg was injected intraperitoneally at 30 min before glycerol was injected intramuscularly in group PHC. At 1 and 6 h after glycerol injection, serum was collected for determination of blood urea nitro?gen ( BUN) and creatinine ( Cr) concentrations, and bilateral kidneys were harvested for pathological ex?amination and for determination of HO?1 activity and expression of Nrf2 mRNA and HO?1 mRNA ( by quan?titative real?time polymerase chain reaction) , Nrf2 in nucleoprotein and total protein and HO?1 in total pro?tein in renal tissues ( by Western blot) . The damage to the renal tubules was scored. Results Compared with group C, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly increased, the expression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was signifi?cantly up?regulated, and HO?1 activity was significantly increased in AKI and PHC groups, the expression of HO?1 mRNA was significantly up?regulated in group AKI, and the expression of Nrf2 mRNA and HO?1 mRNA was significantly up?regulated in group PHC (P<0?01 or 0?05). Compared with group AKI, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly decreased, the ex?pression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was significantly up?regulated, and HO?1 activity was significantly increased in group PHC ( P<0?01 or 0?05) . Conclusion The mecha?nism by which PHC pretreatment attenuates rhabdomyolysis?induced AKI may be related to activation of Nrf2∕HO?1 signaling pathway in renal tissues of rats.

Objective To observe the influence of Buyang Huanwu Decoction ( BYHWD) on the inhibition of rat myocardial H9C2 cell activity and SH2-containing tyrosine phosphatase-1 ( SHP-1) activity induced by trastuzumab, and to explore the possible regulatory mechanism after observing the intervention of BYHWD on rat myocardial H9C2 cell transfected with SHP-1 or SHPC/S-1 gene. Methods The eukaryotic expression vectors pcDNA3.1 (+)- SHP-1 and pcDNA3.1 (+) -SHPC/S–1 were constructed and then were transfected to rat myocardial H9C2 cells using the method of liposome transfection. The cells with positive clones were screened out with G418, and then were cultured with trastuzumab for maintaining growth. Using quantitative RT-PCR, we detected the expression of SHP-1 gene and SHPC/S - 1 gene in rat myocardial H9C2 cells. The phosphatase activity analysis was used for observing the regulatory effect of BYHWD on SHP-1 in myocardial cells. Furthermore, we observed the apoptosis of rat myocardial H9C2 cells by methyl thiazolyl tetrazolium (MTT) assay after treatment with BYHWD. Results Sequencing results indicated the successful construction of eukaryotic expression vectors, which had stable expression in myocardial H9C2 cells even under the intervention of trastuzumab. The results of phosphatase analysis showed that H9C2-SHP-1 had the highest activities of phosphatase, but the activities were decreased after the intervention with BYHWD ( P<0.05) . The results of MTT assay also showed the apoptotic rate of H9C2-SHP-1 cells was decreased after treatment with BYHWD ( P <0.05) . Conclusion BYHWD can promote the proliferation of myocardial H9C2 cells inhibited by trastuzumab, and can regulate the expression of SHP-1 in myocardial cells, which will supply reference to the further study of treatment of trastuzumab-induced cardiac toxicity.

Objective To determine the role of fosinopril and valsartan intervention in Klotho, matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1) and plasminogen activator inhibitor (PAI-1) gene expression in hypertensive renal interstitial fibrosis (RIF) in the kidney tissue of spontaneously hypertensive rats (SHR). MethodsWe randomly divided 20 male 22-week-old SHR into 4 groups (5 in each group):a hypertension group (SHR group), a fosinopril group [Fos group, 10 mg/( kg·d) gavage], a valsartan group [Val group, 10 mg/( kg·d) gavage], and a fosinopril plus valsartan group [Fos + Val group, fosinopril 10 mg/( kg·d) + valsartan 50 mg/( kg·d) gavage]. Another five 22-week-old male Wistar Kyoto rats (WKY) were used as controls. Through monitoring the weight of the rats, tail artery pressure, 24-hour urine protein by fosinopril and/or valsartan intervention after the 8-week trial. RT-PCR and Western blot were used to detect the mRNA and protein expression of Klotho, MMP-9, TIMP-1, and PAI-1 in the kidneys.Results RT-PCR showed that in the SHR group, Klotho mRNA and protein expression were significantly decreased(P<0.01), while mRNA and protein expression of MMP-9, TIMP-1, and PAI-1 were significantly higher compared with the WKY group(P<0.01). With fosinopril and / or valsartan intervention, Klotho mRNA expression in the Fos group (P<0.01), Fos + Val group (P<0.01), Val group (P<0.05), Klotho protein expression in the Fos group(P<0.05), Fos + Val group (P<0.05), Val group (P<0.01), were significantly increased compared with those in the SHR group. The mRNA and protein expression of MMP-9, TIMP-1, and PAI-1 in the Fos group, Val group, and Fos + Val group were significantly lower than those in the SHR group (P<0.01). The expression of Klotho mRNA had negative correlation with the expression of MMP-9 mRNA (r= -0.864, P<0.01), TIMP-1 mRNA (r=-0.725, P<0.01) and PAI-1 mRNA (r=-0.785, P<0.01). The Klotho protein expression had negative correlation with the expression of MMP-9 protein (r=-0.614, P<0.05), TIMP-1 protein (r=-0.579, P<0.05), and PAI-1 protein (r=-0.552, P<0.05). Conclusion Anti-aging gene Klotho and the genes related with extracellular matrix degradation gene MMP-9, TIMP-1, PAI-1 are involved in hypertensive renal injury. The expression of Klotho and MMP-9, TIMP-1, and PAI-1 is closely correlated. Fosinopril and valsartan which increase the Klotho mRNA and protein expression can alter the expression of Klotho-MMPs/TIMPs, which may be the main mechanism to prevent interstitial fibrosis.
