Objective:To investigate the clinical effect of Paris polyphylla var. yunnanensis oral care solution in the prevention of ventilator-associated pneumonia (VAP) in patients with endotracheal intubation in ICU, and to provide reference for continuing to explore the best oral care solution of traditional Chinese medicine for preventing VAP. Methods:Randomized controlled experiment was used. Fifty patients with tracheal intubation admitted to the ICU of the Affiliated Hospital of Yunnan University from May 2022 to February 2023 were selected by convenient sampling method. The patients were divided into control group and observation group with 25 cases in each group by random number table method. The control group was treated with Xipayi mouth rinse for oral care, and the observation group was treated with self-made Paris polyphylla var. yunnanensis oral care solution for oral care. The incidence of VAP, clinical efficacy of oral care, leukocyte and procalcitonin after 7 days of intervention were observed, the mechanical ventilation time and ICU hospitalization time were recorded in the two groups. Results:All patients completed the study. There were 19 males and 6 females in the control group with the age of (60.72±19.32) years old. There were 15 males and 10 females in the observation group with the age of (60.24±16.80) years old. The incidence of VAP after 7 days of intervention in the observation group was 12% (3/25), which was lower than that in the control group 36% (9/25). The difference between the two groups was statistically significant ( χ2=3.95, P<0.05). The total clinical effective rate of oral care after 7 days of intervention in the observation group was 88% (22/25), which was higher than that in the control group 68% (17/25). The difference between the two groups was statistically significant ( χ2=9.78, P<0.01). There was no significant difference in the level of the leucocyte and procalcitonin before and after 7 days of intervention between the two groups (all P>0.05). The mechanical ventilation time and ICU hospitalization time in the observation group were (6.92 ±3.89), (10.36±6.17) days respectively, which were lower than those in the control group (9.72±4.76), (12.12±4.87) days. The difference of mechanical ventilation time between the two groups was statistically significant (t=2.28, P<0.05). The ICU hospitalization time in the observation group was lower than that in the control group, but there was no significant difference between the two groups ( P>0.05). Conclusions:Paris polyphylla var. yunnanensis oral care solution can improve the oral condition of patients, reduce the incidence of VAP, shorten the time of mechanical ventilation, which has certain clinical value.

Objective To study the association of peroxisome proliferator activated receptor?2 (PPAR?2) gene polymorphism with type 2 diabetes mellitus.Methods PPAR?2 gene Pro12Ala polymorphism was examined using polymerase chain reaction and restriction fragment length polymorphism (PCR RFLP) in 101 couples of type 2 diabetes mellitus normal control.Results In control group, heterozygosity carriers had lower serum apolipoprotein B (P=0 006).The Pro12Ala polymorphism in PPAR?2 gene is not associated with type 2 diabetes mellitus(OR=1.48,95%CI=0.52～4.18,P=0.461).Conclusion PPAR?2 gene Pro12Ala polymorphism is associated with abnormal lipid metabolism; PPAR?2 gene may not play a critical role in the development of type 2 diabetes mellitus in Han of Beijing Chinese.
