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 investigate the efficacy of different progestin-primed ovarian stimulation in non-polycystic ovarian morphology(non-PCOM) patients with high ovarian response. Methods A total of 711 cycles for in-vitro fertilization treatment(including 389 embryos transfer cycles) in our hospital from October 2018 to November 2019 were summarized in this retrospective study. All the patients were divided into three groups. In group A, 414 cycles for follicular phase gonadotropin-releasing hormone(GnRH) agonist long protocol(including 232 embryos transfer cycles)was used.

The number of oocytes, 2PN embryos and follicle-to-oocyte index in group B were the highest among the three groups,while the clinical pregnancy rate and implantation rate were the lowest. Luteinizing hormone on human chorionic gonadotropin injection day、estradiol level per follicle in group C were the highest,while FORT and the number of ≥16 mm dominant follicles were the lowest. Conclusion In non-PCOM patients with high ovarian response,follicular phase GnRH agonist protocol had better pregnancy outcome compared with luteal phase GnRH agonist protocol, and the GnRH antagonist protocol appeared to be more economical and safe.

Objective To investigate the clinical efficacy of endoscopic selective varices devascularization and the modified Sandwich method on the treatment of esophagogastric varices. Methods 50 patients with esophagogastric varices were divided into therapy (endoscopic selective varices devascularization)group (n=25) and control group (n=25) by random number table method. The therapy group (n=25) received the treatment of endoscopic selective varices devascularization. The control group (n=25) was treated with modified Sandwich method injection. The success rate of hemostasis, rate of recurrent bleeding, rate of varices disappearance, complication rate, dosage of lauromacrogol and tissue adhesive, time of therapy and hospitalization days were compared and analyzed between the two groups. Results During the 3-month followup, the success rates of hemostasis were 100% in both groups 3 days after the treatments.

The rates of varices disappearance in therapy group and control group were 84%and 52% respectively, the difference (P=0.015) was statistically significant. There was no statistically significant difference in complication rates between the two groups(P>0.05). There was also no statistically significant difference in the average dosage of lauromacrogol and tissue adhesive between the two groups(P>0.05). The average time of therapy in therapy group and control group were(32.60±6.44)minutes and(40.60±7.26)minutes respectively, with statistically significant difference between the two groups(P=0.000). The average hospitalization days in therapy group and control group were(8.12±1.24)days and(9.12±1.39)days respectively, which is statistically significant difference between the two groups(P=0.010).

Objective To explore the clinical value of real-time ultrasound elastography combined with conventional ultrasound in assessing the stability of carotid atherosclerotic plaques in stroke patients. Methods Thirty-four patients with clinically confirmed stroke (stroke group) in our hospital were collected as the research object. Another 56 patients with carotid plaque but without stroke (control group) in the same period were selected as the control object for ultrasonic elastography detection, and the results were analyzed statistically. Results Thirty-four stroke patients were found 57 carotid atherosclerotic plaques, including 29 hypoechoic plaques, 21 mixed echoic plaques and 7 hyperechoic plaques; 56 control patients were found 75 carotid atherosclerotic plaques, including 22 hypoechoic plaques, 25 mixed echoic plaques and 28 hyperechoic plaques. There were significant differences between the number of plaques and the size of plaques (P<0.05). Carotid atherosclerosis low echo, mixed echo and strong echo plaque elasticity score increased in turn, the plaque hardness value increased in turn; the number of plaque scores between the two groups had statistical significance (P<0.05); for the same type of plaque hardness value between the two groups had no significant difference (P>0.05); There were significant differences in hardness values between the same types of plaques (P<0.05). Conclusion Ultrasound elastography may semi-quantitatively evaluate the stability of carotid atherosclerotic plaques in stroke patients. Different types of plaques have different elastic strain rates because of different tissue components. It may effectively complement the information deficiency of conventional ultrasound examination, and then evaluate the stability of plaques.
