RESUMEN
Objective:To study the prognostic risk factors of Enterobacteriaceae bloodstream infection in patients with sepsis.Methods:The medical records of patients with sepsis caused by Enterobacteriaceae bloodstream infection in our hospital from June 2017 to May 2019 were screened. The gender, age, admission department, basic disease, infection site, etiology examination and treatment plan were recorded in detail. The survival and death groups were divided according to the patient's survival status. The ratio of C-reactive protein (CRP) to serum prealbumin (PA) was recorded within 24 h after admission. The acute physiological and chronic health scores (APACHEⅡ score) and Pitt bacteremia score (PBS score) were calculated within 24 h, and based on the results of blood culture drug sensitivity test to analyze whether the initial experience treatment was appropriate. Logistic regression analysis was used to analyze the risk factors affecting the prognosis of patients, and the receiver operating characteristic curve (ROC curve) was drawn to predict the occurrence of poor prognosis in patients with sepsis.Results:Logistic regression analysis showed that CRP ( OR=1.021, P<0.01), CRP/PA ( OR=34.638, P<0.01), extended-spectrum β-lactamase production ( OR=0.244, P<0.01), inappropriate empirical antibacterial treatment ( OR=0.156, P<0.01), APACHE Ⅱ score ( OR=1.436, P<0.01), and PBS score ( OR=8.622, P<0.01) were risk factors affecting patient's prognosis. Multivariate regression analysis showed that CRP/PA ( OR=25.420, P<0.05), inappropriate empirical treatment ( OR=0.077, P<0.05), APACHEⅡ score ( OR=1.476, P<0.01), PBS score ( OR=12.042, P<0.01) were independent risk factors for death in patients with sepsis ( P<0.05). The higher the CRP/PA level, PBS score and APACHEⅡ score, the worse the prognosis. When CRP/PA ≥0.89, PBS score ≥3.5, APACHEⅡ score ≥17.5, the patient's risk of death increased significantly. In addition, inappropriate empirical treatment was also a key factor in patients with poor prognosis. Conclusions:CRP/PA, PBS score, APACHE Ⅱ score, and inappropriate empiricaltreatment are independent risk factors affecting the prognosis of patients with enterobacter hemorrhagic infection with sepsis. The PBS score and APACHEⅡ score can better predict the poor prognosis and risk of death. Compared with APACHEⅡscore, the former is simpler and practical and can be widely used.

Objective To investigate the sedative effects of different doses of dexmedetomidine with mid-azolam in spinal anesthesia. Methods 130 cases of spinal anesthesia were randomly divided into 2 groups,group D1 and group D2,with 65 cases in each group. Patients in 2 groups were given midazolam and dexmedetomidine with different doses. The heart rates ,blood pressure ,SpO2 ,Narcotrend value and Ramsay sedation scores were recorded at mutiple time points. The working time ,maintaining time of sedative effect ,and adverse reactions were compared between 2 groups. Results MAP,HR and NT decreased significantly in 2 groups(P < 0.05,respec-tively). The keeping time was relatively longer in group D1 compared with group D2(P<0.05). The working time was faster in group D2 compared with group D1. The rate of bradycardia in group D2 was relatively higher than that in group D1. Conclusion Good sedative effect can be obtained by drug in 2 groups. Group D1,with midazolam 0.05 mg/kg+dexmedetomidine 0.3μg/kg,may have a certain advantage in anaesthesia in the spinal canal.
RESUMEN
Background:The incidence of gastric cancer is gradually rising in recent years,long non-coding RNA taurine up-regulated gene 1 (TUG1)may have certain effects on the occurrence and progression of gastric cancer. Aims:To study the expression TUG1 in gastric cancer tissue and its effect on prognosis of patients with gastric cancer,and study the correlation between TUG1 and p27,cyclin D1. Methods:Surgically resected gastric cancer tissues and corresponding distal normal tissues of 48 gastric cancer patients from June 2013 to December 2013 at Qingdao Municipal Hospital were collected. qRT-PCR was used to detect the mRNA expression of TUG1,and its relationship with clinicopathological features was analyzed. Protein expressions of p27 and cyclin D1 were determined by Western blotting,and correlation with expression of TUG1 was analyzed. Kaplan-Meier was used to analyze the relationship between expression of TUG1 and prognosis. Results:The mRNA expression of TUG1 in gastric cancer tissues was significantly higher than that in corresponding normal tissues (6. 18 ± 0. 19 vs. 5. 09 ± 0. 16,P < 0. 05),and was not correlated with gender,age,tumor size,but correlated with lymph node metastasis,tumor differentiation and TNM staging (P < 0. 01). The protein expression of p27 was significantly decreased in gastric cancer tissues than in normal tissues (0. 1709 ± 0. 0212 vs. 0. 3087 ± 0. 0252,P < 0. 01),while protein expression of cyclin D1 was significantly increased (0. 3417 ± 0. 0271 vs. 0. 2417 ± 0. 0173,P < 0. 01),and the expression of p27 was negatively correlated with expression of cyclin D1 in gastric cancer tissues (r = - 0. 897,P < 0. 01). The expression of TUG1 was negatively correlated with expression of p27 (r = - 0. 730,P < 0. 01),and was positively correlated with expression of cyclin D1 (r = 0. 809,P < 0. 01)in gastric cancer tissues. The median survival time was shorter in gastric cancer patients with high-expressed TUG1 than in patients with low-expressed TUG1 (P < 0. 05). Conclusions:Long non-coding RNA TUG1 plays a role of cancer gene in the development of gastric cancer through p27 /cyclin D1 pathway. Detection of expression of TUG1 has important significance on the prediction of prognosis of gastric cancer patients.

RESUMEN
Objective:To investigate the expression of maternally expressed gene 3 (MEG3), a long non-coding RNA gene, in gastric can-cer tissues;determine the relationship of MEG3 with the prognosis of gastric cancer;and explore the relationship between MEG3 and apoptosis-associated protein P53 as well as murine double minute 2 (MDM2). Methods:Fifty-five consecutive patients with gastric cancer admitted to Qingdao Municipal Hospital for surgical treatment from September 2012 to June 2013 were included in this study. Gastric cancer and paired normal tissues were collected. The expression of MEG3 was tested through real-time quantitative poly-merase chain reaction (qRT-PCR). Western blot analysis was used to detect the expression of P53 and MDM2 in gastric cancer and eval-uate their correlations with MEG3. Results:The expression of MEG3 decreased in cancer tissues (7.98±0.19) relative to the correspond-ing normal tissues (9.47±0.18) (P<0.05). P53 and MDM2 showed negative relationships in the gastric cancer and normal tissues. A posi-tive relationship was found between P53 and MEG3 (r=0.591, P<0.05), whereas a negative relationship was found between MDM2 and MEG3 (r=?0.346, P<0.05). The median survival time was significantly prolonged in patients with high MEG3 expression compared with patients with low MEG3 expression. Conclusion:MEG3 exerts an inhibiting effect on the development of gastric cancer. MEG3, P53, and MDM2 may have important relationships in the biological mechanisms of gastric cancer development. Detecting the expression level of MEG3 may be useful for the prognosis of gastric cancer.

RESUMEN
Background:As an important catalytic subunit of telomerase,human telomerase reverse transcriptase (hTERT)plays an important role in the development and progression of many cancers including gastric cancer.It has been reported that several single nucleotide polymorphisms (SNPs)of hTERT had varying degrees of association with risk of neoplasms. Aims:To study the correlation between SNPs of hTERT rs2853676 and rs2853677 and susceptibility to gastric cancer. Methods:Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotypes of rs2853676 and rs2853677 of hTERT in 297 gastric cancer patients,105 atrophic gastritis and 402 controls. Helicobacter pylori (Hp)infection was detected by pathological examination and 13 C-urea breath test.Results:Frequency of AA genotype of rs2853676 was significantly higher in gastric cancer group when compared with control group (15.2%vs.6.5%,P =0.01).The risk of gastric cancer in AA genotype carriers increased 2.47-fold (95% CI:1.46-4.16) when compared with GG carriers.No significant differences in the frequencies of CC,TC and TT genotypes of rs2853677 were found among gastric cancer patients,atrophic gastritis patients and controls.Hp infection rates in atrophic gastritis group and gastric cancer group were significantly increased than those in controls (64.8%,56.9% vs.40.3%,P all <0.01),OR were 2.73 (95% CI:1.74-4.26),1.96 (95% CI:1.44-2.67),respectively.Logistic regression analysis showed that there was no significant interaction between Hp infection and gene mutation.Conclusions:Polymorphism of hTERT gene rs2853676 may play a role in susceptibility to gastric cancer,and Hp infection may not be involved in the increase of risk of gastric cancer caused by hTERT gene polymorphism.
RESUMEN
Background and purpose: Syndecan-1 and HPA-1 may be involved in the progression of invasion and metastasis of many malignant tumors, but there are few reports about the relationship between the two gene expressions in gastric carcinomas. This study was aimed to explore the expression of Syndecan-1 and HPA-1 mRNA in gastric carcinoma and their relationship with the invasion and metastasis of gastric carcinoma. Methods: Real-time polymerase chain reation (RT-PCR) was used to detect mRNA of Syndecan-1 and HPA-1 in 58 cases of gastric carcinoma, 58 paired adjacent gastric carcinoma (2 cm from carcinoma), and 58 surgical marginal normal gastric mucosa tissues (5 cm from carcinoma). Then we analyzed their relationship with clinico-pathological characteristics of gastric carcinoma. Results: The upregulation of Syndecan-1 mRNA was significantly higher in normal gastric mucosa (98.3%) than that in paired adjacent mucosa (25.9%) and gastric carcinoma (5.2%) (all P<0.001).The upregulation of Syndecan-1 mRNA was significantly higher in paired adjacent mucosa than that in gastric carcinoma (all P<0.05). The upregulation of HPA-1 mRNA was significantly higher in gastric carcinoma (86.2%) than that in paired adjacent gastric carcinoma (27.6%) and normal gastric mucosa (5.2%) (P<0.001). The upregulation of HPA-1 mRNA was significantly higher in paired adjacent gastric carcinoma than that in normal gastric mucosa (all the same P<0.05). The downregulation of Syndecan-1 and the upregulation of HPA-1 had relationship with the degree of differentiation, depth of infiltration, lymph node metastasis, distant metastasis and TNM staging of gastric carcinoma (P<0.05). Conclusion: The upregulation of Syndecan-1 mRNA was significantly higher in normal gastric mucosa. The upregulation of HPA-1 mRNA was significantly higher in gastric carcinoma. Also, the expression of Syndecan-1 and HPA-1 could predict the invasion and metastasis of gastric carcinoma. Determination of Syndecan-1 and HPA-1 may be of value in the treatment as well as in the prediction for prognosis of gastric cancer.
