Objective: The study aimed to investigate the impact of polyethylene glycol - conjugated recombinant human growth hormone (PEG - rhGH) treatment on immune function in children with growth hormone deficiency (GHD), by analyzing changes in lymphocyte subsets, immunoglobulin levels, and T helper cell (Th1/Th2) cytokines before and after treatment. Methods: Fifty - five children diagnosed with GHD were enrolled as study participants from May 2022 to June 2023 at the Department of Pediatrics of Huai' an First People's Hospital and Hongze District People's Hospital. According to the preferences of the participants, they were allocated into a control group (n=25) and a PEG-rhGH group (n=30) . The control group received guidance on exercise, diet, and sleep, while the PEG-rhGH group received PEG-rhGH treatment in addition to these interventions. Measurements of height, bone age, BMI, insulin-like growth factor -1 (IGF -1), lymphocyte subsets, Th1/Th2 cytokines, and immunoglobulin (Ig) levels were conducted at baseline and 3 months post-treatment. The changes in various parameters before and after the intervention were compared. Results: Before treatment, there were no significant differences in the baseline levels of the various indicators between the two groups. After 3 months of treatment, the standard deviation of height, growth rate, and serum IGF - 1 level in the PEG - rhGH group significantly increased compared to pre - treatment levels and were notably higher than those in the control group. After treatment, the PEG - rhGH group demonstrated a significantly higher proportion of CD3+, CD4+ and CD4+ /CD8+ as well as elevated levels of IgA, IgM, and IgG compared to the control group, while the proportion of CD8+ cells was notably lower in the PEG-rhGH group than in the control group, There were no significant differences in the proportion of CD19 + and CD3- CD16 + CD56 + cells between the two groups. Additionally, the levels of Th1/Th2 cytokines, interleukin (IL) -2, IL-6, and tumor necrosis factor-α (TNF-α) in the PEG-rhGH group were significantly lower after treatment compared to before, and were significantly lower than those in the control group. There were still no significant differences in the levels of IL-4 and interferon-γ (IFN-γ) between the two groups. Conclusion: PEG-rhGH treatment not only improves the height of GHD children but also affects their cellular immunity and humoral immunity. [ABSTRACT FROM AUTHOR]

Efficient, water-saving irrigation modes are commonly used in the sugarcane fields of latosolic red soils in the Guangxi Zhuang Autonomous Region, China. This research studied the effects of different irrigation treatments on photosynthetic characteristics of sugarcane. Because photosynthesis is an important process in plant dry matter accumulation, this research has implications for the development of high-efficiency cultivation methods that produce high yields of sugarcane. We planted the sugarcane cultivar Liucheng 05-136 under 6 types of irrigation modes: no irrigation, subsurface drip irrigation, surface drip irrigation, pipe irrigation, sprinkler irrigation, and micro sprinkler irrigation. Field measurements of net photosynthetic rate and related environmental factors(soil water content, soil temperature, air temperature, relative air humidity, soil organic matter, soil available nitrogen, soil available phosphorus, and soil available potassium content) were conducted at the Sugarcane Efficient Water-saving Irrigation Test Base in Chongzuo City from March to December, 2015 for different growth phases of sugarcane(tillering stage, early, peak and late stages of elongation, and maturation stage). Additionally, the differences in net photosynthetic rate of sugarcane under different irrigation modes were investigated with a multiple comparison method, and the relationship between environmental factors and net photosynthetic rate was analyzed using stepwise regression and path analysis. Results showed that the mean net photosynthetic rates of sugarcane under no irrigation, subsurface drip irrigation, surface drip irrigation, pipe irrigation, sprinkler irrigation, and micro sprinkler irrigation were 18.53, 29.23, 28.50, 26.65, 25.94 and 23.66 μmol/(m2·s), respectively. Net photosynthetic rate was the lowest under the no irrigation mode, while the highest value appeared under the subsurface drip irrigation mode, which was 57.74%, 23.54%, 12.68%, 9.68% and 2.56% higher than that of no irrigation, pipe irrigation, sprinkler irrigation, micro sprinkler irrigation and surface drip irrigation, respectively. Therefore, irrigation can significantly improve sugarcane photosynthetic rate(P<0.05). Path analysis results showed that soil water content, air temperature and soil fertility were the main environmental factors influencing sugarcane net photosynthetic rate on the whole, but some differences existed between irrigation modes. Soil fertility was a key variable for photosynthetic rate under no irrigation and subsurface drip irrigation, while soil water content and soil available nitrogen content had significant effects on photosynthetic rate under surface drip irrigation. In the case of pipe irrigation, soil available potassium and air temperature were the major factors. For sprinkler and micro sprinkler irrigation, the main factors were soil water content and air temperature. It may adjust the influence of irrigation treatments on photosynthesis through the regulation of environmental factors(air temperature and humidity, and soil physical and chemical properties). In addition, each factor mutually acts to promote or restrain the photosynthesis process, showing a comprehensive effect. In terms of soil water content, its influence on photosynthesis was reflected in the effect on absorption of nitrogen, phosphorus and potassium nutrient elements for sugarcane under no irrigation, subsurface and surface drip irrigation modes. Comprehensive analysis showed that the subsurface drip irrigation treatment effectively improved sugarcane photosynthesis. Subsurface drip irrigation will be more suitable for the cultivation of sugarcane in the latosolic red soils in the Guangxi Zhuang Autonomous Region. Furthermore, according to the different irrigation modes, ensuring favorable control of soil water content in combination with other main influencing factors, can further improve sugarcane net photosynthetic rate, and consequently increase the yield of sugarcane.
