Efficacy and safety of transscleral cyclophotocoagulation versus cyclocryotherapy in the treatment of intractable glaucoma: A systematic review and meta-analysis.

To perform a meta-analysis to compare the efficacy and safety of diode laser transscleral cyclophotocoagulation (TSCPC) and cyclocryotherapy (CCT) in the treatment of intractable glaucoma. Systemic searches of the Ovid MEDLINE, EMBASE, and Cochrane Library databases yielded experimental and observational comparative studies. TSCPC and CCT efficacy and safety outcomes were compared. Subgroup analyses of participant ethnicity, preoperative intraocular pressure (IOP) level, and underlying causes of glaucoma were conducted. The pooled effects were computed using the random-effects model. The meta-analysis included nine studies totalling 668 eyes. There was no statistically significant difference between the TSCPC and CCT groups in the IOP reduction (IOPR%), decrease in antiglaucoma medications, the operative success rate with or without medications, or retreatment rate in the efficacy analysis. In the subgroup analysis, CCT had a better IOP-lowering effect among non-Asian participants and a non-inferior IOPR% to TSCPC among Asian participants. TSCPC and CCT were associated with similar rates of deterioration in visual acuity, postoperative visual analog scale, and other analysed postoperative complications in the safety analysis. In both groups, severe complications were uncommon. Diode laser TSCPC and CCT had nearly equivalent clinical efficacy in treating intractable glaucoma, while CCT demonstrated a better IOP-lowering effect in non-Asian. Both cyclodestructive procedures have a comparable safety profile.

Potential antidepressant effects of a dietary supplement from Huáng qí and its complex in aged senescence-accelerated mouse prone-8 mice.

Healthcare is an emerging industry with significant market potential in the 21st century. Therefore, this study aimed to evaluate the benefits of tube feeding Huáng qí and its complexes for 8 weeks on 3-month-old senescence-accelerated mouse prone-8 (SAMP8) mice, 48 in total, randomly divided into 3 groups including control, Huáng qí extract [820 mg/kg Body weight (BW)/day], and Huáng qí complexes (6.2 mL /kg BW/day), where each group consisted of males (n = 8) and females (n = 8). Behavioral tests (locomotion test and aging score assessment on week 6, the single-trial passive avoidance test on week 7, and the active shuttle avoidance test on week 8) were conducted to evaluate the ability of the mice to learn and remember. In addition, after sacrificing the animals, the blood and organs were measured for antioxidant and aging bioactivities, including malondialdehyde (MDA) content and superoxide dismutase (SOD) activity and catalase activities (CAT), and the effects on promoting aging in SAMP8 mice were investigated. The findings showed that Huáng qí enhanced locomotor performance and had anti-aging effects, with positive effects on health, learning, and memory in SAMP-8 mice (p < 0.05), whether applied as a single agent (820 mg/kg BW/day) or as a complex (6.2 mL/kg BW/day) (p < 0.05). Based on existing strengths, a more compelling platform for clinical validation of human clinical evidence will be established to enhance the development and value-added of astragalus-related products while meeting the diversified needs of the functional food market.

Lower proximal cup and outer root sheath cells regenerate hair bulbs during anagen hair follicle repair after chemotherapeutic injury.

The cell dynamics and cell origin for anagen hair follicle (HF) repair following chemotherapeutic injury are unclear. We first mapped the HF response to cyclophosphamide (CYP) at natural anagen VI in mice. We found that 30-60 mg/kg of CYP leads to dose-dependent HF dystrophy that was spontaneously repaired with anagen resumption, while 120 mg/kg of CYP prematurely induced catagen/telogen entry. To explore how anagen HF repair is achieved in the dystrophic anagen pathway, we analysed the cell dynamics at 30 mg/kg of CYP. Hair bulbs first shrunk due to matrix cell apoptosis associated with DNA double-strand breaks. DNA damage was repaired, and ordered hair bulb structures were restored within 96 hours. Bulge stem cells did not undergo apoptosis nor proliferation. K5+ basal lower proximal cup cells and outer root sheath cells quickly replenished the cells in the germinative zone and regenerated the concentric layered structures of the lower HF segment. Therefore, anagen HFs are able to summon extra-bulge progenitor cells in close proximity to the damaged matrix for quick repair after CYP injury.

Effect of gonadotropin-releasing hormone agonist on ES-2 ovarian cancer cells.

OBJECTIVE: Gonadotropin-releasing hormone (GnRH) receptor is found in the ovarian tissue, including epithelial ovarian cancer (EOC), suggesting that GnRH agonists may have direct action on EOC. MATERIALS AND METHODS: Ovarian clear cell cancer (ES-2) cells were treated with low-dose GnRH agonist with/without low-dose paclitaxel (1 µM D-Lys(6) with/without 0.5 µM or 1.0 µM paclitaxel). Growth and behavior of ES-2 cells were evaluated. RESULTS: Use of either D-Lys(6) or paclitaxel or a combination of the two did not affect the morphology and growth pattern of ES-2 cells. However, ability of migration and invasion of ES-2 cells was significantly decreased in either use of D-Lys(6) or paclitaxel and more apparent with the combination. Type I GnRH receptor expression of ES-2 was not altered significantly by the combination. CONCLUSION: GnRH agonist might modify the ES-2 ovarian cancer cells, and its role might be independent, additional or synergistic, suggesting the potential role of the use of GnRH agonist in the management of clear cell type of the ovarian cancer. However, the results of this study were derived using ES-2 ovarian cancer cells, and might not be valid in other cell types of ovarian cancers.

Pumpkin (Cucurbita moschata) fruit extract improves physical fatigue and exercise performance in mice.

Pumpkin (Cucurbita moschata) is a popular and nutritious vegetable consumed worldwide. The overall purpose of this study was to evaluate the effects of C. moschata fruit extract (CME) on anti-fatigue and ergogenic functions following physiological challenges. Male ICR mice from four groups designated vehicle, CME-50, CME-100 and CME-250, respectively (n = 8 per group in each test) were orally administered CME for 14 days at 0, 50, 100 and 250 mg/kg/day. The anti-fatigue activity and exercise performance were evaluated using exhaustive swimming time, forelimb grip strength, as well as levels of plasma lactate, ammonia, glucose, and creatine kinase after an acute swimming exercise. The resting muscular and hepatic glycogen was also analyzed after 14-day supplementation with CME. Trend analysis revealed that CME treatments increased grip strength. CME dose-dependently increased 5% body weight loaded swimming time, blood glucose, and muscular and hepatic glycogen levels. CME dose-dependently decreased plasma lactate and ammonia levels and creatine kinase activity after a 15-min swimming test. The mechanism was relevant to the increase in energy storage (as glycogen) and release (as blood glucose), and the decrease of plasma levels of lactate, ammonia, and creatine kinase. Therefore, CME may be potential for the pharmacological effect of anti-fatigue.

Serum interleukin-6 levels, not genotype, correlate with coronary plaque complexity.

An increased serum interleukin-6 (IL-6) level is associated with an increased risk of cardiovascular events in healthy subjects. However, it is unknown whether the level of serum IL-6 or genetic IL-6 polymorphism is correlated with the complexity of coronary plaque in patients with stable coronary artery disease (CAD). Patients with stable CAD (n = 135) were divided into 3 groups: insignificant coronary plaque (n = 77), simple coronary plaque (n = 15), and complex coronary plaque (n = 43). IL-6-174G > C polymorphism and serum levels of IL-6 and C-reactive protein (CRP) were investigated. No significant difference in the distribution of IL-6 genotypes was found among the groups. The presence of complex coronary plaque was associated with higher serum concentrations of IL-6 (P = 0.026) and CRP (P < 0.0001). To predict the presence of complex lesions, IL-6 > 5.8 ng/L and CRP > 2.6 mg/L had sensitivities of 86% and 74%, and specificities of 61% and 62%, respectively. By multivariate analysis, IL-6 > 5.8 ng/L and CRP > 2.6 mg/L were independently related to the presence of complex coronary plaque (P = 0.0002 and 0.004, respectively). IL-6 > 5.8 ng/L and CRP > 2.6 mg/L were associated with a 4.5-fold increase in the odds of having complex coronary plaque (P < 0.005). A simple measurement of the serum IL-6 level in patients with CAD can potentially identify subjects with complex coronary lesions and provide the option of aggressive medical strategies in a clinical setting.
