Objective To investigate the influences of carbon dioxide (CO2) pneumoperitoneum and operation position on intraocular pressure (IOP) during laparoscopic surgery under general anesthesia. Methods Thirty-six patients were divided into two groups of udergoing laparoscopic pelvic surgeries (group A) and udergoing laparoscopic cholecytectomies(group B) with 18 cases each. The patients in group A were operated under 25 degrees head-down position and those in group B under 25 degrees head-up position. IOP was recorded before surgery(T0), at 5 min after tracheal intubation (T1), 5 min after CO2 pneumoperitoneum(T2), 5 min(T3) and 30 min(T4) after body position changed and the time of normal PETCO2 regained(T5). Results IOP was remarkably decreased after induction of general anesthesia in both groups. IOP of group A raised to (21.0±1.6) mm Hg at T4, which was dropped to (14. 6±1.6) mm Hg at T5. IOP of group B raised to (12.1±2.9) mm Hg at T4,which was dropped to (11.1±1.2) mm Hg at T5. Changes of IOP of both groups were positively correlated with the changes of PETCO2. Conclusion IOP can be decreased remarkably after induction of general anesthesia with propofol. The head-up position and normal range of PETCO2 are the two important factors to avoid an increase of IOP in surgical patients under general anesthesia.

The DNR decision in EDs has not been extensively studied, especially in the Chinese mainland. METHODS: This retrospective chart study of all deceased patients in the ED of a university hospital was conducted from January 2017 to December 2019. The patients with out-of-hospital cardiac arrest were excluded. RESULTS: There were 214 patients’ deaths in the ED in the three years. Among them, 132 patients were included in this study, whereas 82 with out-of-hospital cardiac arrest were excluded. There were 99 (75.0%) patients’ deaths after a DNR order medical decision, 64 (64.6%) patients signed the orders within 24 hours of the ED admission, 68 (68.7%) patients died within 24 hours after signing it, and 97 (98.0%) patients had DNR signed by the family surrogates. Multivariate analysis showed that four independent factors influenced the family surrogates’ decisions to sign the DNR orders: lack of referral (odds ratio [OR] 0.157, 95% confidence interval [CI] 0.047-0.529, P=0.003), ED length of stay (ED LOS) ≥72 hours (OR 5.889, 95% CI 1.290-26.885, P=0.022), acute myocardial infarction (AMI) (OR 0.017, 95% CI 0.001-0.279, P=0.004), and tracheal intubation (OR 0.028, 95% CI 0.007-0.120, P<0.001). CONCLUSIONS: In the Chinese mainland, the proportion of patients consenting for DNR order is lower than that of developed countries. The decision to sign DNR orders is mainly affected by referral, ED LOS, AMI, and trachea intubation.

Background:The morbidity and mortality of gastric cancer remain high worldwide,and it is urgent to explore new targets for the diagnosis and treatment of gastric cancer. Nuclear protein 1 (Nupr1)has a variety of biological functions, especially in the tumorigenesis and development of the malignancies. Aims:To investigate the expression and clinical significance of Nupr1 in gastric cancer. Methods:Quantitative RT-PCR was used to determine the mRNA expression of Nupr1 in 72 cases of gastric cancerous tissue and the paired paracancerous tissue. Western blotting and immunohisto-chemistry were employed to detect the protein expression and cellular localization of Nupr1. The correlation of Nupr1 with the clinicopathological characteristics of gastric cancer was analyzed. Results:Expressions of Nupr1 mRNA and protein in gastric cancer were both significantly higher than those in paracancerous tissue (P < 0. 05),and their expressions were coincident. Nupr1 protein was expressed mainly in cytoplasm,and the nuclear expression was reduced. Expression of Nupr1 mRNA in gastric cancer was significantly correlated with tumor size,differentiation,pathological type,Bormann's classification,depth of invasion,lymph node and distant metastases and TNM staging (P < 0. 05),and was not correlated with gender,age and site of tumor (P > 0. 05). Conclusions:Nupr1 is overexpressed and correlated with invasion, metastasis and progression of gastric cancer. It can be used as a novel biomarker for early diagnosis and prognosis evaluation,and as a potential target for treatment of gastric cancer.
