ABSTRACT
Vertical greenery system (VGS) is a sustainable solution to promote building energy saving and emission reduction, mitigate the urban heat island effect, as well as a crucial component of urban ecological construction. We summarized four main mechanisms of the thermal effects of VGSs, including shading effect, evapotranspiration effect, thermal insulation effect, and wind control effect. We elucidated the effects of VGSs on building cooling and energy saving, and analyzed the cooling effects of VGSs on plant canopy and outdoor ambient air, as well as their influence on mitigating the urban heat island effect. Based on available research on the thermal effects of VGSs, we identified key directions for future research, aiming to expedite the development of green cities and achieve carbon neutrality.

This report describes the clinical characteristics, treatment, and pathologic mechanisms of neonatal ultrahyperpyrexia syndrome induced by improper care. Clinical data on 14 cases of neonatal ultrahyperpyrexia syndrome induced by improper care were retrospectively analyzed. All 14 neonates had become comatose with ultrahyperpyrexia or hyperpyrexia; 8 of these patients twitched, 12 had high muscular tension, 2 exhibited low muscle tone, and 9 had respiratory dysfunction. Computed tomography revealed a patched, low dense shadow in the frontal and parietal lobes of the cerebral cortex in 9 patients; local cerebral hemorrhage occurred in 3 cases, and subarachnoid hemorrhage was reported in 2. After systematic treatment was provided, 13 neonates survived, but 1 died. Dysfunction of the neural, respiratory, and circulatory systems was the main pathologic mechanism noted in these cases of neonatal ultrahyperpyrexia syndrome induced by improper care. Early treatment, acute hypothermia, and supplemental fluids are the keys to successful therapy.

AIM: To investigate the effects of qiongyugao on the expression of hepatitis B x antigen (HBxAg) in BALB/c-nu mice into which human hepatic carcinoma cells were transplanted, and to analyze its specific mechanism in prophylaxis and treatment of hepatocellular carcinoma. METHODS: A nude mouse model with the transplantation of human hepatic carcinoma cells was established to observe the preventive and therapeutic effects of qiongyugao on the body weight and tumor weight of the mice. The expression of HBxAg in tumor and liver tissue wsa detected by immunohistochemical studies. RESULTS: Compared with model control group, prophylaxis and treatment with qiongyugao increased the body weight, depressed the tumor weight and inhibited HBxAg expression. The same efficacy was showed in both qiongyugao prophylaxis group and cyclophosphamide treatment group. CONCLUSION: Qiongyugao can slow down the growth of tumor and inhibit the expression of HBxAg, which may be an essential mechanism in prophylaxis and treatment of hepatocellular carcinoma.
