Objective To investigate the clinical effect of positive end-expiratory pressure(PEEP) ventilation guided by transpulmonary pressure (Ptp) in acute respiratory distress syndrome (ARDS). Methods Between January and October 2020, 100 cases of ARDS treated in intensive care unit were randomly divided into control group and observation group with 50 cases each. Control group used auxiliary control small tidal volume ventilation therapy, and observation group used the best PEEP mechanical ventilation therapy with the guiding of Ptp. The respiratory dynamics index, blood gas analysis results, follow-up of 28d case fatality rate before and 48h after treatment between the two groups were compared. Results After 48h of treatment, tidal volume、PEEP、pulmonary static compliance、PaCO₂、PaO₂、SaO₂、PaO₂/FiO₂ of the observation group were all higher than those of the control group (P<0.05). There was no statistically significant difference in mortality between the two groups at 28d follow-up (P＞0.05). Conclusion Mechanical ventilation with the best PEEP guided by Ptp could effectively improve the respiratory dynamic index and blood gas analysis results of patients with ARDS, without increasing the mortality of ARDS, which is worthy of clinical application.

Objective To study the effect of ureteroscopic holmium laser lithotripsy in the treatment of ureteral calculi and its effect on oxidative stress. Methods Sixty patients with ureteral calculi admitted to our hospital from March 2016 to April 2017 were randomly divided into control group and observation group, with 30 cases in each group. The observation group received ureteroscopic holmium laser lithotripsy and the control group received conventional open surgery. We compared inflammatory factors such as interleukin-10 (IL-10), C-reactive protein (CRP), and white blood cells (WBC) before and after surgery, as well as cortisol (Cor), malondialdehyde (MDA), and superoxide dismutase (SOD) and other levels of oxidative stress indicators, while comparing the two groups of debris. Results The operation time and hospitalization days in the observation group were lower than those in the control group. The stone removal rate was higher than that in the control group (P<0.05). After operation, the IL-10, CRP and WBC in the observation group were higher than those in the control group (P< 0.05). Cor and MDA in the observation group were lower than the control group, and SOD was higher than the control group (P<0.05). Conclusion Ureteroscopic holmium laser lithotripsy is effective in the treatment of ureteral calculi. It can inhibit inflammatory factors, reduce stress response, and promote the recovery of patients' diseases. It is worthy of clinical promotion.

Objective To explore the influence of stress management on the improvement of quality of life of middle-aged patients with hypertension. Methods According to convenience sampling, 115 middle-aged patients with hypertension who were the first time admitted to our hospital were divided, on the basis of different periods, into the test group (60 patients) and the control group (55 patients).
