Objective To explore the security of spinal anesthesia by observing the pefioperation serum troponin T in the elderly patients with coronary heart disease who underwent spinal anesthesia.Methods 40 case8 were divided into two groups according to the elderly patients with or without the history of coronary heart disease.Group Ⅰ 0f 20 cases were the patients with the history of coronary heart disease.Group Ⅱ of 20 cases were the patients without the history of coronary heart disease.Both groups were undertaken single spinal anesthesia combined with epidural anesthesia.The blood samples were collected at the time of perioperation,the end of the operation and 24 hours after surgery.The serum troponin T Was tested by Roche fully automated ehemiluminescent analyzer E170.The symptoms and signs of the coronary heart disease in the patient were observed.And the age,operation time,anesthesia lever,the amount of bleeding and transfusion were recorded,and at the same time,electrocardiogram,heart rate,pulse,cerebral oxygen saturation were monitored.Results There was no significant difference between two groups in age,operation time,anesthesia lever,the amount of bleeding and transfusion,heart rate,pulse,cerebral oxygen saturation.There was no significant difference between two groups in seram troponin T.No symptoms and signs of the coronary heart disease were observed in two groups.There Was no significant difference between two groups in constituent ratio of positive rate of serum troponin T.There was one case in each group that serum lroponin T was more than reference value (0.010μg/L)during the perioperation while the patient was no discomfort.Conclusion Spinal anesthesia has no impact on the change of perioperative 8ertlm troponin T in the elderly patients with coronary heart disease.

Objective:
To investigate the association between single nucleotide polymorphisms (SNP) in cytokine IL6, IL10 genes and the susceptibility to primary hepatic carcinoma(PHC) of Shunde district in Guangdong Province.
Methods:
Patients from two hospitals in Shunde District of Foshan City were selected from October 2010 to October 2012. Case group inclusion criteria includedprimary liver cancer; local residents of Shunde or living in Shunde for more than 10 years. The control group inclusion criteria included: patients visited ENT, general surgery and physical examination department in the same hospital during the same period; Local residents or living in Shunde for 10 years and above. The control group was matched 1∶1 by gender, and age (±3 years old) with case group. A total of 306 subjects were collected. Questionnaires were used to investigate the information including demographic characteristics, PHC status survey and so on. The venous blood was collected from each subject to extract DNA, and to detect label SNP site and genotype. Hardy-Weinberg equilibrium was detected in the control group by the goodness-of-fit χ2 test. Multivariate conditional logistic regression was used to estimate the relationship between IL6 (rs1800796), IL10 (rs1800871, rs1800872)genes polymorphisms and susceptibility to PHC.
Results:
There were 264 males and 42 females both in the case group and the control group, with an average age of (55.84±11.49) and (55.83±11.67) years old respectively (

Objective:To explore the feasibility of bedside ultrasound in monitoring gastric residual volume and predicting feeding intolerance during enteral nutrition in critically ill patients in intensive care unit.Methods:The data of critically ill patients admitted to emergency intensive care unit of the Second Affiliated Hospital of Zhejiang University School of Medicine from April 2018 to September 2018 were retrospectively analyzed. The following patients were finally included in this study: (1) abdominal computed tomography during the stay of emergency intensive care unit was performed due to the requirement of disease evaluation and management; (2) bedside ultrasound was performed to measure the gastric antrum cross-sectional area at 30 min prior to or after abdominal computed tomography. The outline of stomach wall in the imaging of abdominal computed tomography was traced with the help of VOLUME-Work Flow medical imaging software to calculate the value of gastric residual volume. The relationship between gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions and gastric residual volume was evaluated by Pearson correlation analysis. The difference of gastric antrum cross-sectional area between those critically ill patients with or without feeding intolerance was compared by independent-sample t test. The predictive value of gastric antrum cross-sectional area under different body positions on feeding intolerance during enteral nutrition was analyzed by ROC curve. Results:Totally, forty-two patients were enrolled and analyzed in this study, in which the mean age was (53±13) y, mean body mass index was (21.5±2.8) kg/m 2 and mean acute physiology and chronic health evaluation was 17.0±6.9. The value of gastric residual volume was (314.5±126.6) mL, and the values of gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions were (7.11±4.13) cm 2, (4.22±2.66) cm 2, (8.36±4.58) cm 2, respectively. The correlation analysis indicated that gastric residual volume was positively associated with gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions ( r=0.543, 0.604 and 0.618, respectively; all P<0.001). During enteral nutrition, 15 patients experienced feeding intolerance while 27 patients hadn’t feeding intolerance, in which the gastric antrum cross-sectional areas under semi-sitting, horizontal and right-lateral positions were significantly increased in those patients with feeding intolerance than those patients without feeding intolerance [semi-sitting: (8.53±4.07) cm 2vs (4.60±2.76) cm 2; horizontal position: (5.15±2.75) cm 2vs (2.61±1.32) cm 2; right-lateral position: (10.32±4.06) cm 2vs (4.95±3.20) cm 2, all P<0.005] . ROC curve analysis showed that the area under ROC curves of gastric antrum cross-sectional area under semi-sitting, horizontal and right-lateral positions for predicting feeding intolerance during enteral nutrition were 0.815, 0.833 and 0.849, respectively; when its values≥3.917 cm 2, 3.395 cm 2 and 4.402 cm 2 were used as the cut-off points, the sensitivities were 92.0%, 69.6% and 92.3%, and the corresponding specificities were 69.2%, 92.3% and 71.4%, respectively. Conclusions:Bedside gastric ultrasound could accurately evaluate the status of gastric residual volume in critically ill patients, and effectively predict their occurrence of feeding intolerance during enteral nutrition.

OBJECTIVE:
To investigate the effect of danusertib (Danu), an inhibitor of Aurora kinase, on the proliferation, cell cycle, apoptosis, and autophagy of hepatocellular carcinoma HepG2 cells and explore the underlying mechanisms.
METHODS:
MTT assay was used to examine the effect of Danu on the viability of HepG2 cells to determine the IC50 of Danu. The effect of Danu on cell cycle distribution, apoptosis and autophagy were determined using flow cytometry. Western blotting was used to detect the expressions of the proteins related to cell cycle, apoptosis and autophagy. Chloroquine was used to suppress Danuinduced autophagy to test the apoptosis-inducing effect of Danu.
RESULTS:
Danu significantly inhibited the proliferation of HepG2 cells with IC of 39.4 μmol and 14.4 μmol at 24 h and 48 h, respectively. Danu caused cell cycle arrest in G/M phase in HepG2 cells and led to polyploidy accumulation via up-regulating the expressions of p53 and p21 and down-regulating the expressions of cyclin B1 and DC2. Danu also caused apoptosis of HepG2 cells through up-regulating the expressions of Bax, Puma, cleaved caspase-3, cleaved caspase-9, cleaved PARP and cytochrome C and down-regulating the expressions of Bcl-xl and Bcl-2. Danu induced autophagy via activating AMPK signaling and inhibiting PI3K/PTEN/AKT/mTOR axis, and inhibition of Danu-induced autophagy with chloroquine enhanced the pro-apoptotic effect of Danu.
CONCLUSIONS
Danu inhibits cell proliferation and induces cell cycle arrest in G/M phase, apoptosis and cytoprotective autophagy in HepG2 cells.
