Objective To explore the influencing factors of prognosis and nursing strategies in sepsis combined with gastrointestinal dysfunction.Methods The clinical data of 102 patients with sepsis and gastrointestinal dysfunction who were admitted to Traditional Chinese Medicine Hospital of Guangdong Province(The Second Affiliated Hospital of Guangzhou University of Chinese Medicine)between June 2022 and December 2023 were retrospectively analyzed.According to the prognosis within 30 d,the patients were assigned to death group(n=38)or survival group(n=64).Clinical indexes were compared between the two groups.The main influencing factors of prognosis were analyzed by Logistic regression,and targeted nursing strategies were summarized.Results The mortality in the patients with sepsis and gastrointestinal dysfunction was 37.25%(38/102).Univariate analysis showed that age,Sequential Organ Failure Assessment(SOFA)score,Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score,gastrointestinal failure(GIF)score,and stay time in ICU were all influencing factors of prognosis in patients with sepsis and gastrointestinal dysfunction(all P<0.05).Logistic regression analysis showed that age≥65 years,SOFA score>6,APACHEⅡscore>17,GIF score>3,and stay time in ICU>7 d were independent risk factors of poor prognosis in patients with sepsis and gastrointestinal dysfunction(all P<0.05).Conclusion The poor prognosis of patients with sepsis and gastrointestinal dysfunction is related to age,SOFA score,APACHEⅡscore,GIF score,and stay time in ICU.It is essential to take preventive and nursing measures for these risk factors to reduce the incidence of poor prognosis.

Objective To investigate the expression level and clinical significance of long non-coding RNA(LncRNA) growth arrest specific gene-antisense 1(GAS8-AS1) in papillary thyroid microcarcinoma(PTMC) patients. Methods We investigated the expression profile of GAS8-AS1 in tissue samples of patients with PTMC as well as nodular goiter(NG) by quantitative real-time polymerase chain reaction(RT-qPCR). Results GAS8-AS1 in cancer tissue was down-regulated in PTMC patients compared with adjacent thyroid tissue and NG samples(P<0.05). Lower level of GAS8-AS1 was also correlated with central cervical lymph node metastasis(CLNM, P<0.05). The area under the ROC curve for GAS8-AS1 was up to 0.717 3 in CLNM prediction(P<0.05). Conclusion GAS8-AS1 may act as a potential biomarker for PTC diagnosis and CLNM prediction.

ObjectiveTo detect the fiber structure and volume differences in frontal lobe between patients with amnestic mild cognitive impairment (aMCI) and normal control.MethodsT1 -weighted magnetic resonance imaging and diffusion tensor imaging were obtained in 28 aMCI patients and 25 normal controls.Volumes,fiber fractional anisotropy (FA),fiber apparent diffusion coefficient (ADC),fiber number,and average fiber length of frontal lobe in the two groups were measured.ResultsVolumes of left frontal lobe ( ( 337.35 ± 20.45 ) cm3 ) in aMCI group were smaller than control ( (358.54 ± 27.26) cm3 ) ( t =- 3.223,P =0.002 ).Numbers of short range fiber in left frontal lobe ( 16985 ± 892) were significantly increased relative to control ( 16387 ±752) ; while numbers of long range fiber (3214 ± 185 ) were reduced compared with control (3425 ± 277 ),and ADC values increased ( t =2.621,P =0.012; t =-3.714,P =0.001 ; t =17.595,P=0.000).In aM CI group,numbers of long range fiber in right frontal lobe were reduced (2895 ± 343 vs.3451 -± 230,t =- 7.011,P =0.000),and ADC values were increased ( t =4.443,P =0.000).In aMCI group,numbers of long range fiber in left frontal lobe were positively correlated with scores of mini-mental state examination ( MMSE ) ( r =0.457,P =0.015 ),while ADC values of long range fiber in left frontal lobe were negatively correlated with scores of MMSE ( r=-0.415,P=0.028).ConclusionThe structure and fiber connectivity are affected in aMCI patients and the lesion of connectivity in left frontal lobe are related to the severity of symptom.

Objective To compare the results of three kinds of heart preservative fluids,namely histidine-tryptophan-ketoglutarate(HTK)solution,Fuwai modified solution(FWM)and St.Thomas' Hospital cardioplegic solution number 2(St.Thomas-Ⅱ)for the preservation of isolated rat hearts under low temperature.Methods Fifty-four male SD rats were randomly divided into HTK,FWM and ST-Ⅱ groups(18 each),and each group was divided into three subgroups(6 each)according to different duration of preservation under low temperature(4,6 and 8 hours).The hearts were harvested and then mounted on the Langendorff apparatus and perfused with K-H buffer solution for determination of the baseline hemodynamic values(HR,LVSP,?dp/dtmax and CF).The isolated hearts were then arrested and stored in different preservative solution as mentioned at 4℃ for 4,6 or 8 hours.The hemodynamic values were measured before cardiac arrest and after cardiac reperfusion in Langendoff model,and the recovery rates of the values were calculated.The hearts were finally sectioned after reperfusion for the observation of morphological changes with light microscope.Results With the same hypothermic preservation time,the recovery rates of hemodynamic values were significantly higher,and the changes in myocardial structures were obviously less in HTK and FWM groups than in ST-Ⅱ group(P0.05).Conclusions HTK and FWM solutions are more effective than St.Thomas-Ⅱsolution in preservation of isolated heart under low temperature with the same storage duration.The effect of HTK solution for preservation of isolated heart descended with the prolongation of preservation time,especially so after 8 hours.
