    Abstract Objective: Inflammatory bowel disease (IBD) is a chronic nonspecific inflammatory bowel disease with an unclear etiology. The active ingredients of traditional Chinese medicines (TCMs) exert anti-inflammatory, antitumor, and immunomodulatory effects, and their multitarget characteristics provide them with a unique advantage for treating IBD. However, the therapeutic effects and underlying mechanisms of Xi Lei San in treatment of IBD remain unknown. This study was designed to investigate whether Xi Lei San exerted an anti-inflammatory effect in IBD via a mechanism involving NLRP3 inflammasomes and autophagy.
    Methods: We successfully established a rat model of dextran sulfate sodium- (DSS-) induced colitis as well as a cellular model of TNF-
    Results: Xi Lei San and indirubin were identified by HPLC analysis. We found that Xi Lei San could significantly increase the weights of rats and improve the structure of the intestinal tissues in DSS-induced colitis model rats. We also found that Xi Lei San significantly inhibited NLRP3 inflammasome activity, reduced the levels of inflammatory cytokines, and suppressed autophagy in DSS-induced colitis model rats.
    Conclusions: Our findings showed that Xi Lei San significantly ameliorated IBD by inhibiting NLRP3 inflammasome, autophagy, and oxidative stress.

    Abstract Salt stress, causing serious loss on crop productions, is one of the most important environmental stresses throughout the world. The aim of this study is to select salt-tolerant traditional rice resources collected from Lei-Qiong area of South China and investigate their physiological performances and biochemical regulations during salt stress response, together with two well-known international varieties, Nona Bokra (salt-tolerant sample) and IR29 (salt-sensitive sample). After comprehensive analyses, we discovered that two Lei-Qiong traditional salt-tolerant rice samples showed less growth inhibition by salt stress during both germination and seedling stage, in comparison with other rice samples. Moreover, there were less chlorosis symptoms in these two kinds of salt tolerant rice under salt stress, corresponding to their better water-holding capacity. We measured malondialdehyde and proline contents, and activities of CAT and POD of seedlings treated with 100 mM NaCl for 5 dand 10 d, respectively. Interestingly, less cellular membrane damage and stronger antioxidant enzyme system were found in the two Lei-Qiong rice samples. Our study suggests that traditional rice landrace growing onshore of Lei-Qiong area in China possesses good salt-tolerant capacity, which could be attributed to their efficient antioxidant enzyme system.

    Abstract Lei bamboo (Phyllostachys praecox) is widely distributed in southeastern China. We used eddy covariance to analyze carbon sequestration capacity of a Lei bamboo forest (2011-2013) and to identify the seasonal biotic and abiotic determinants of carbon fluxes. A machine learning algorithm called random forest (RF) was used to identify factors that affected carbon fluxes. The RF model predicted well the gross ecosystem productivity (GEP), ecosystem respiration (RE) and net ecosystem exchange (NEE), and displayed variations in the drivers between different seasons. Mean annual NEE, RE, and GEP were -105.2 ± 23.1, 1264.5 ± 45.2, and 1369.6 ± 52.5 g C m

Bamboo forest, also known as “the second largest forest in the world,” plays an important role in the carbon cycle. Due to its high economic value, IM practices have been widely used to manage bamboo forests, which in turn may affect the global carbon cycle and carbon budget balance of the ecosystem. However, due to a lack of long-term field experiments and suitable representative models for carbon cycle research in bamboo forests, there is little understanding of the effects of IM measures on carbon sources/sinks in bamboo forest ecosystems at large temporal scales. In this study, we used a representative Lei bamboo (Phyllostachys praecox C.D. Chu & C.S. Chao) forest occurring in Taihuyuan town, Zhejiang Province, China as the study object and a new generation Triplex-Flux model to simulate the net ecosystem productivity (NEP) and net primary productivity (NPP) of the Lei bamboo forest under IM and non­intensive management (NIM) in 2011–2013 and 2015. The aim was to reveal the impact of IM on the carbon cycle of a bamboo forest ecosystem. The results showed that the Triplex-Flux model was suitable for studying the carbon cycle in the Lei bamboo forest. On a 30 min time scale, R² values ranged between 0.78–0.91 (p<0.01) and the RMSE varied between 0.04–0.09 gC m⁻¹. On a daily scale, the model was also able to simulate the NEP of the Lei bamboo forest (R²>0.42, p<0.001). However, the Triplex-Flux model failed to reveal the NEP patterns, as there were certain deviations between some of the simulated NEP peak and valley values, which were underestimated at noon and overestimated at night. IM played a key role in controlling carbon budget of the Lei bamboo forest. On a seasonal scale, the effect of IM measures was the most significant in spring; harvesting old bamboo wood and removing new shoots caused a 27.71% and 58.52% decrease in NEP and NPP, respectively. Hooking tips and trimming diseased branches had little impact on NEP and NPP (0.02% and 7.27%, respectively) in autumn. On an annual scale, IM measures resulted in average annual decrease in NEP and NPP by 27.20% and 13.72%, respectively. Our findings can provide a reference base that may be applicable to studying the carbon cycle in bamboo forests across the country and even at larger scales.

Summer drought played little role in suppressing GEP, but low soil moisture contents suppressed RE and increased the carbon sink during drought in the summer. The most important drivers of NEE were soil temperature in spring, summer, and winter, and photosynthetically active radiation in autumn. Air and soil temperature were important drivers of GEP in all seasons.

    Abstract: ... ground temperature, and precipitation in a intensively managed Lei bamboo forest ecosystem in 2011 ...

    Abstract By using open-path eddy covariance system and meteorological instruments, an observation was conducted on the sensitive heat flux, latent heat flux, net radiation, soil heat flux, air temperature, ground temperature, and precipitation in a intensively managed Lei bamboo forest ecosystem in 2011, with the diurnal and monthly variations of energy flux as well as the distribution pattern of each energy component analyzed, and the Bowen ratio and energy balance closure calculated. The yearly net radiation of the forest ecosystem was 2928. 92 MJ m-2, and the latent heat flux, sensitive heat flux, and soil heat flux were 1384.90, 927.54, and -28.27 MJ m-2, respectively. Both the daily and the monthly variations of the energy components showed a single peak curve. The sensible and latent heat fluxes were 31.7% and 47.3% of the net radiation, respectively, indicating that latent heat flux was the main form of energy loss. The Bowen ratio followed the "U"-shaped pattern, and fluctuated from 0. 285 to 2. 062, suggesting that soil was a heat source. The yearly energy balance closure of the forest ecosystem was 0. 782, and the monthly average was 0.808.

  8. Article: Responses of seasonal and diurnal soil CO₂ effluxes to land-use change from paddy fields to Lei bamboo (Phyllostachys praecox) stands

    Abstract: ... the hypothesis. In Lei bamboo stands, the R² for the soil respiration-temperature regression was higher using ... that the conversion of paddy fields to Lei bamboo stands decreased the annual soil CO₂ efflux but increased ...

    Abstract Land-use change often markedly alters soil carbon (C) dynamics such as soil surface CO₂ efflux. This study aims to test the hypotheses that converting paddy fields to bamboo stands would markedly reduce soil CO₂ efflux and their temperature sensitivity (change of soil CO₂ efflux rate by increasing 10 °C of temperature), and change the relationship between soil CO₂ efflux and other environmental factors. A 12-month field study was conducted to measure the seasonal and diurnal soil CO₂ effluxes in three adjacent paddy field-bamboo forest pairs with the automated soil CO₂ flux system (LI-8100). Results showed that soil CO₂ effluxes from both of the two land-uses had distinct seasonal patterns, and were reduced from 45.4 to 34.7 t CO₂ ha⁻¹ yr⁻¹ in cumulative CO₂ emissions when paddy fields were converted to bamboo stands. About 80% of the variation in soil respiration in the bamboo stands was explained by soil temperature; however, a positive relationship between soil CO₂ efflux and soil temperature in the paddy field was observed only when the soil was not submerged under water, indicating that soil water saturation in the paddy fields altered the soil CO₂ efflux–temperature relationship. A negative relationship (P < 0.01) between soil CO₂ efflux and soil moisture was observed in the paddy fields, while no such relationship was observed in the bamboo stands. The apparent temperature sensitivity of soil respiration (Q₁₀) was dependent on the depth of the soil temperature measurement and was increased by converting paddy fields to bamboo stands, rejecting the hypothesis. In Lei bamboo stands, the R² for the soil respiration-temperature regression was higher using seasonal and diurnal CO₂ efflux data together than using the seasonal data alone. We conclude that the conversion of paddy fields to Lei bamboo stands decreased the annual soil CO₂ efflux but increased its temperature sensitivity, and altered the relationship between soil respiration and soil moisture. When calculating the Q₁₀, the soil temperature measurement depth and data with diurnal timescale should be taken into account. If such land-use conversion effects are confirmed over the subtropical region in China in future research, this land-use conversion could increase C sequestration in the ecosystem and help mitigate climate change.
