碩士 / 國立陽明大學 / 微生物及免疫學研究所 / 102 / Defects in angiogenesis or collateral vessel development are major complications of metabolic syndrome such as diabetes mellitus (DM). Endothelial progenitor cells (EPCs) play a fundamental role in post-natal vascular repair. The number, as well as the activity, of circulating EPCs in DM patients has been reported to be impaired in DM progression. Far-infrared (FIR) transfers energy into the form of heat which can be perceived by the thermoreceptors in human skin as radiant heat. Several studies revealed that infrared sauna therapy could improve vascular endothelial functions and boost angiogenesis. FIR has been widely used in clinical treatment for anti-inflammatory therapy and improving peripheral circulation. In addition to occlusive vascular repairing, increasing evidence showed that FIR is likely to be applied in a variety of cardiovascular disorders, hypertension and arthritis. Yet mechanisms of FIR and biomarkers to indicate FIR effects are unclear. Here we show that FIR treatment improves EPCs functions, and the angiogenic activities of EPCs are correlated to the exposure time of FIR. We find high glucose (HG)/DM-EPCs possess poor angiogenic activities and the lowest level of NRIP1 (RIP140), a FIR-induced gene in EPCs. Moreover, miR-134, an anti-angiogenic microRNA filtrated from the small RNA sequencing and bioinformatics analysis, was found to target NRIP1 and up-regulated in HG/DM-EPCs. Knocking down miR-134 in HG/DM-EPCs restored the expression level of NRIP1 and EPCs angiogenic activities. Both miR-134 and NRIP1 could be affected by FIR. In conclusion, our results reveal that FIR treatment can help EPCs activation, and the deregulation of miR-134 would eventually lead to angiogenic defects in DM patients. FIR holds the potential to develop a new phototherapy for DM patients, for cultured DM-EPCs autograft, and for concentrated PBMC blood transfusion. Detection of the expression of miR-134 in FIR-treated EPCs should help to examine the effectiveness of phototherapy. Manipulating the expression of miR-134 in malfunction EPCs may also be another therapeutic approach.

碩士 / 長庚大學 / 早期療育研究所 / 102 / Background and purpose: Late-preterm infants are defined as infant born between 34 0/7 and 36 6/7 weeks' gestation and account for majority of all preterm births. In clinical practice, late preterm infants are often considered functionally and developmentally mature and managed as term neonates. Accumulating data indicate that risks of mortality, morbidity and neurodevelopment problems are significantly greater in late preterm infants than previously believed. However, the extent of developmental outcomes of late preterm infants in their early years remains largely under-researched in Taiwan. Apart from biological factors, child development is affected by home environment and caregivers’ characreristics based on the theories of Ecological or Transactional Model. To our knowledge, the risk factors for poorer development outcome of late-preterm infants have not been exhaustively investigated in Taiwan using cohort studies. Therefore, the purpose of this study was to explore the predictability of late preterm (vs full term) and the related covariant (biological and environmental factors) on the development outcomes using cohort study design. Methods: We use cohort study design. The multiple developmental outcomes are used to compared the group differences between 18 late preterm infants (34 0/7 to 36 6/7 weeks of gestation) at corrected age of 4 months and 100 full term infants ( >37 weeks of gestation) at chronological age of 4 months, including the Comprehensive Development Inventory for Infants and Toddlers (CDIIT), the Alberta Infant Motor Scale (AIMS) and the Peabody Developmental Motor Scales Second Edition (PDMS-2). The predictors of developmental outcomes included biological factors, maternal and environmental factors (family characteristics) and General movements assessment (GMs). Chi-square test was conducted to investigate the associations between biological / environmental factors and late preterm (vs full-term). Multiple logistic regression and multiple linear regression were used to examine the predictability of pre-term (vs full-term) on dichotomous developmental outcome (AIMS <10 percentile) and continuous developmental outcomes (CDIIT developmental quotients [DQs] and PDMS-2 DQs) controlling for related biological and environmental factors. Results: Mothers of the late preterm infants, compared with mothers of term infants, were more likely to have perinatal illness history (33.3% vs 6%, respectively, p= .000). Hypoglycemia and hyperbilirubnemia requiring phototherapy were more likely to occur in late preterm infants (2% vs 0%, respectively, p= .02; 50% vs 19%, respectively, p= .01). Late preterm infants had statistically significant higher percentage of AIMS <10 percetile (50% vs 10%, respectively, p= .000). Multiple logistic regression analysis indicates that late preterm was a significant factor for adverse motor outcome measured by AIMS (Adjusted OR=6.8, 95% [1.61~28.68], p= .01) controlling for related biological and environmental factors. Regarding the developmental outcomes measured by CDIIT and PDMS-2, though late-preterm itself was not a significant predicator for developmental outcomes, we found phototherapy requiring phototherapy predict significant lower DQs for late-preterm infants than full-term infants in CDIIT cognition DQs(CDIIT cognition DQs, B=-8.51, 95% [-14.43~-2.58], p= .005), CDIIT motor DQs (CDIIT fine motor DQs, B=-6.19, 95 % [-11.46~-.93], p= .022), PDMS-2 total motor DQs (PDMS-2 total motor DQs, B=-4.79, 95% [-7.41~-2.11], p=.000); PDMS-2 gross motor DQs (PDMS-2 gross motor DQs, B=-4.26, 95% [-6.73~1.79], p=.001) and PDMS-2 fine motor DQs (PDMS-2 fine motor DQs, B=-4.5, 95% [-7.21~-1.68], p= .002). Infants of mother with higher education level had lower CDIIT self-help DQs (CDIIT self-help DQs, B=-3.1, 95 % [-6.19~-.01], p= .049. Small for gestational age (SGA) infants were more often had lower PDMS-2 total motor DQs (PDMS-2 total motor DQs B= 4.66, 95 % [.16~9.16], p= .042) and PDMS-2 gross motor DQs (PDMS-2 gross motor DQs, B= 4.56, 95 % [.34~8.78], p=.035). Conclusions: Late preterm infants at mean corrected age 4 months old are at a relatively higher risk of motor-related developmental problems compared with full-term infants at mean chronological age 4 months old. Based on the multiple outcome indexes, the risk factors for the development of infants at 4 month age were late-preterm and hyperbilirubnemia requiring phototherapy, maternal higher educational level and small for gestational age (SGA). Clinical implications: Though late-preterm infants are at relative lower biologically risks for developmental outcomes, the delay in motor development can be recognized as early as 4 months of age. Further research regarding long-term follow-ups is needed to explore whether “catch-up” in later life emerge for infants born late preterm. The strategies of preventing pregnant women from having late-preterm infants, periodically surveillance and follow-ups for late-preterm infants, and instructions and support for their families would be the responsibilities of related health care providers and early interventionists.

碩士 / 國立交通大學 / 應用化學系碩博士班 / 102 / With the gradual enhancement of environmental awareness, the development of green luminescent materials has been an important issue in phosphors research. This research is attempted to synthesize and investigate new UV-emitting materials, which can be excitated by 172 nm and used for the applications of phototherapy, sterilization, and disinfection. We have explored and investigated the luminescence mechanism of four series of UV-emitting phosphors, including nine types of rare earth-doped phosphates, silicates and borates. In this study, using the vacuum ultraviolet (VUV) light source provided by National Synchrotron Radiation Research Center (NSRRC), as well as the X-ray diffraction technique and electron microscopy analysis, we have prepared and investigated UVB-emitting NaCa(Y,Gd) (PO4)2, Na2(Y,Gd)2O(BO3)2, Li6(Y,Gd)(BO3)3, Na(Y,Gd)Si2O6, NaCa (Y,Pr,Gd)(PO4)2, Li6(Y,Pr,Gd)(BO3)3 and Na(Y,Pr,Gd)Si2O6; UVC- emitting NaCa(Y,Pr)(PO4)2 and Na(Y,Pr)Si2O6. Under excitation at 172 nm, the NaCa(Y,Gd)(PO4)2, Na2(Y,Gd)2O(BO3)2, Li6(Y,Gd)(BO3)3, Na(Y,Gd)Si2O6, NaCa(Y,Pr,Gd) (PO4)2, Li6(Y,Pr,Gd)(BO3)3 and Na(Y,Pr,Gd)Si2O6 phosphors were found to give sharp UVB emission centered at 313 nm, which was attributed to the 4f7→4f7 transition of Gd3+. Under the same excitation, NaCa(Y,Pr)(PO4)2 and Na(Y,Pr)Si2O6 were found to emit UVC light, which was found to be due to the 4f15d1 →4f 2 transition of Pr3+. With the co-doping of Pr3+ as a sensitizer, NaCa(Y,Pr,Gd)(PO4)2, Li6(Y,Pr,Gd)(BO3)3, and Na(Y,Pr,Gd) Si2O6 exhibit a much stronger emission at 313 nm. The emission intensity of the UVB-emitting NaCa(Y0.8293Pr0.0007Gd0.17)(PO4)2, Li6(Y0.695Pr0.005 Gd0.3)(BO3)3 and Na(Y0.775Pr0.005 Gd0.22)Si2O6 was found to be 1.6, 5.4, and 1.4 times that of the UVB emission of the patented LaB3O6:Bi3+,Gd3+ commodity, respectively. Our investigation results indicate that the above three Pr3+/Gd3+-coactivated phosphors may have great potential for practical application in phototherapy and tanning. The luminescence performance of all types of UV radiation was found to be crucially dependent on the chemical compositions, bonding and crystal structure of the host matrix.

碩士 / 國立成功大學 / 生物醫學工程學系 / 100 / Sufficient evidence suggests that phototherapy can improve wound healing of diabetes with no side effects. The purpose of this study is to evaluate the effect of organic light-emitting diode (OLED) phototherapy in diabetic rat model. Thirty diabetic rats were used and divided into treatment and control groups. In treated rats, the left-flank wound was irradiated with 610 ~ 670 nm OLED wavelength peak at 632 nm, 4 J/cm2, 3 mW/cm2, 22.22 minutes every two days. The right flank of treatment group and both sides of controls were not irradiated. To assess the treatment effects, the wound area was evaluated by image processing software (ImageJ) as well as from the hemoglobin concentration measurement on the wound surrounding area using near infrared spectroscopy (NIRS). Furthermore, the tissue structure was evaluated using hematoxylin and eosin (H＆E) staining and the skin tension of wound closure was measured using tensile tests. Our study indicated that significant differences (p 〈 0.01) between treatment-irradiated and control group for percentage of wound contraction during the wound healing. The NIRS results showed that the hemoglobin concentration on the wound of control was higher than that of treatment group at the proliferation phase. The high hemoglobin concentration might be related to the protracted inflammatory response of diabetic wound. Skin tensile strength of treatment group was 2.6 times higher (p 〈 0.05) than that of control at two months after surgery. The H＆E staining showed that the leukocyte infiltration of control was more serious than treatment group on 10 and 22 days post surgery. In summary, the OLED phototherapy can accelerate the healing rate, reduce the inflammatory reaction, and improve the skin tensile strength.

The photophysical properties of porphyrin and phthalocyanine photosensitisers for the photodynamic therapy of cancer (PDT), sterically hindered porphyrins and a novel chemotherapeutic agent (Mitoxantrone), have been investigated using the time resolved techniques of laser flash photolysis, pulse radiolysis, fluorescence and near infrared luminescence. Current topics of interest in PDT and phototherapy of neonatal jaundice are the use. of 5-aminolaevulinic acid to stimulate the formation of protoporphyrin IX for treatment of tumour and skin lesion, and the formation of the potentially cytotoxic species, lumirubin, by green light irradiation of infants with hyperbilirubinemia. Continuous irradiation, and steady state techniques have been used to study the photoproduct, and singlet oxygen formation, by these systems. The effect of environment on the photophysical properties of haematoporphyrin has been studied. It was found that under certain conditions the triplet state lifetime and relative quantum yield are enhanced. The results of this have been used to suggest an explanation for enhanced singlet oxygen yields in such environments. A novel water soluble phthalocyanine with no peripheral substitution, but the axial ligands conferring the desired property, has been studied and found to have a triplet state lifetime in aqueous solution of approximately O.7J.1s, and a singlet oxygen yield of zero. Yet this phthalocyanine has been reported to be efficient sensitizer for the photodynamic therapy of cancer. This supports current discussions that mechanisms other than type II (singlet oxygen) could be of significance in the destruction of tumours.
