[Clinical efficacy of Longjintonglin Capsules on chronic prostatitis with damp-heat stasis syndrome Re-evaluation based on multicenter real-world study].

OBJECTIVE: To re-evaluate the clinical efficacy of Longjintonglin Capsules (LJTL) in the treatment of chronic prostatitis with damp-heat stasis syndrome. METHODS: This multicenter real-world study included 1 352 cases of chronic prostatitis with damp-heat and stagnation syndrome treated with LJTL (3 capsules once, tid, 30 minutes after meals, for 2 four-week courses) in addition to routine treatment. Before and after treatment, we analyzed the NIH-CPSI scores, the scores of Chinese medicine symptom quantitative classification and changes in individual symptom scores, and observed adverse reactions to medication. RESULTS: The total effectiveness rate of LJTL was 93.64%. Compared with the baseline, the NIH-CPSI scores were significantly decreased after treatment (ï¼»24.27 ± 6.04ï¼½ vs ï¼»8.17 ± 4.21ï¼½, P < 0.05), and so were the scores on the pain symptoms (ï¼»9.63 ± 3.65ï¼½ vs ï¼»3.02 ± 2.23ï¼½, P < 0.05), voiding symptoms (ï¼»5.65 ± 2.15ï¼½ vs ï¼»1.62 ± 1.36) and quality of life (ï¼»8.96 ± 2.32ï¼½ vs ï¼»3.16 ± 1.89ï¼½, P < 0.05). The effectiveness rate of LJTL was 95.9% on the Chinese medicine symptom frequent urination, 90.4% on painful urination, and 91.4% scanty dark urine, with a total effectiveness rate of 82.4% － 95.9%, all with statistically significant difference in comparison with the baseline (P < 0.05). CONCLUSION: Longjintonglin Capsules combined with routine treatment can significantly improve the clinical symptoms of chronic prostatitis with damp-heat stasis syndrome, especially effective on the symptoms of frequent urination, painful urination and scanty dark urine. Besides, it recommendable for its antidepressant and antianxiety effects, and the effect of improving the quality of life of the chronic prostatitis patients with damp-heat stasis.

Density-Dependent Growth and Fitness in Dastarcus helophoroides (Coleoptera: Bothrideridae).

The ectoparasitoid Dastarcus helophoroides Fairmaire (Coleoptera: Bothrideridae) is an important natural enemy insect, which is artificially mass-reared and released into woodland to control medium and large longhorn beetle species. This study examined the developmental duration (days) of larvae and adult fitness (including numbers of adults emerging per host and mean body size) by exposing a single substitute host, a pupa of Zophobas morio (Coleoptera: Tenebrionidae), to different densities of D. helophoroides larvae. We showed that there was no significant effect on the rate of successful parasitism and cocoon formation, but emergence success and measures of individual adult body size (length, width, and weight) declined with increasing larval density. Larval period and cocoon period increased with larval density, while total weight of adults emerging per host increased initially before reaching a plateau. Our results suggest that a pupa of Z. morio could be successfully parasitized by a single D. helophoroides larva, but multiple D. helophoroides larvae can share one host. Excessive larval density caused intraspecific competition among D. helophoroides larvae, manifesting in extended developmental duration of immature stage and reduced fitness of adults. Furthermore, the tradeoff between the numbers of adults and body size may stabilize the population dynamics with detectable mutual interference, particularly in competing for limited host resources. These findings suggest six larvae per host would achieve the highest adult fitness and would enhance mass-rearing techniques as part of IPM strategies for longhorn beetles.

Three-dimensionally porous graphene: A high-performance adsorbent for removal of albumin-bonded bilirubin.

The development of bilirubin adsorbents with high adsorption efficiencies towards albumin-bonded bilirubin is still a considerable challenge. In this work, a three-dimensionally porous graphene (3D-pGR) has been fabricated through a simple carbon dioxide (CO2) activation of thermally exfoliated graphite oxide (EGO). Intriguingly, the resultant 3D-pGR material showed hierarchically micro-meso-macroporous structure, high specific surface area of up to 843m2g-1, and large pore volume as high as 2.71cm3g-1. Besides, the large planar π-configuration structure of 3D-pGR made it possible to compete effectively with albumin for bilirubin binding. Taking advantages of these fantastic characteristics, the 3D-pGR was demonstrated to be extraordinarily efficient for bilirubin removal from a bovine serum albumin (BSA)-rich solution. Under optimized conditions, the maximum adsorption capacity of 3D-pGR for BSA-bonded bilirubin was up to 126.1mgg-1, which is not only significantly higher than the adsorption capacities of currently available adsorbents towards albumin-bonded bilirubin, but also superior to those of many reported adsorbents towards free bilirubin. In addition, the hemolysis assay of 3D-pGR indicated that this material had negligible hemolysis effect. Findings from this study may open up important new possibilities for removal of protein-bonded toxins.

Partial-Redox-Promoted Mn Cycling of Mn(II)-Doped Heterogeneous Catalyst for Efficient H2O2-Mediated Oxidation.

The development of a heterogeneous catalyst with high catalytic activity and durability for H2O2-mediated oxidation is one of the most important industrial and environmental issues. In this study, a Mn(II)-doped TiO2 heterogeneous catalyst was developed for H2O2-mediated oxidation. The TiO2 substrate-dependent partial-redox behavior of Mn was identified on the basis of our density functional theory simulations. This unique redox cycle was induced by a moderate electron transfer from Ti to Mn, which compensated for the electron loss of Mn and finally resulted in a high-efficiency cycling of Mn between its oxidized and reduced forms. In light of the theoretical results, a Mn(II)-doped TiO2 composite with well-defined morphology and large surface area (153.3 m2 g-1) was elaborately fabricated through incorporating Mn(II) ions into a TiO2 nanoflower, and further tested as the catalyst for oxidative degradation of organic pollutants in the presence of H2O2. Benefiting from the remarkable textural features and excellent Mn cycling property, this composite exhibited superior catalytic performance for organic pollutant degradation. Moreover, it could retain 98.40% of its initial activity even in the fifth cycle. Our study provides an effective strategy for designing heterogeneous catalytic systems for H2O2-mediated oxidations.
