Objective To investigate the related factors and preventive measures of delayed gastric emptying after operation for esophageal and cardiac carcinoma.Methods A total of 45 patients with delayed gastric emptying after operation for esophageal and cardiac carcinoma were selected as observation group,and 45 patients without delayed gastric emptying after operation for esophageal and cardiac carcinoma were selected as control group.Differences in the relevant factors were compared between the two groups.Results Single factor analysis showed that older age,high body mass index,short time education,malnutrition,poor mental state,rural residence,surgical incision,blood loss,long operation time,postoperative analgesia pump application,and the large amount of fluid volume were related risks of delayed gastric emptying (P ＜ 0.05).The Logistic regression analysis showed that older age (OR =4.15,95 ％ CI:1.89 ～ 26.30),bad psychological reaction (OR =3.96,95％ CI:1.38 ～ 25.38),long operation time (OR =3.40,95％ CI:1.11 ～ 20.28) and malnutrition (OR =3.02,95％ CI:1.09 ～ 19.35) were independent factors of delayed gastric emptying.Conclusion Delayed gastric emptying is one of the common complications after operation for esophageal and cardiac carcinoma,and the influencing factors are complex.

Exosomes are extracellular vesicles released from various cellular sources and are widely present in body fluids. Bioactive substances such as microRNAs, mRNAs, and proteins are encapsulated in exosomes, which can activate various signaling pathways and play important roles in early warning of stroke and neurovascular unit repair. This article reviews the signal transduction of exosomes in cerebral ischemia.

Micro RNAs are a kind of conserved short non-coding RNAs that regulate life activities at molecular level. Micro RNAs are active in various stages of autophagy after ischemic stroke; micro RNAs play protective or destructive roles in autophagy after stroke. Based on the autophagy process, we discuss the possible mechanism of autophagy regulated by micro RNAs through autophagy related genes or pathways, and analyze the application prospect of micro RNAs in stroke diagnosis and treatment.

Objective To explore the prognostic values of telomerase reverse transcriptase promoter (TERTp) mutation and 1p/19q co-deletion in newly-diagnosed O6-methylguanine-DNA methyltransferase (MGMT) promoter un-methylated/isocitrate dehydrogenase (IDH) wild-type glioblastoma multiform (GBM). Methods A total of 82 patients pathologically newly-diagnosed MGMT promoter un-methylated/IDH wild-type GBM, admitted to our hospitals from March 2016 to November 2018, were included in this study. TERTp mutations (TERTp wild-type and TERTp mutation [C228 mutation and C250 mutation]) in GBM specimens were detected by PCR sequencing, 1p/19q co-deletion in GBM specimens was detected by fluorescence in situ hybridization (FISH), and clinical data, adverse reactions and prognoses of patients with different molecular typing were compared. Results There were 33 patients in the TERTp wild type group with mean age of 48 years, and 49 patients in the TERTp mutation group with mean age of 59 years; the difference of age was significant (P<0.05); there were no statistical differences in gender distribution, Karnofsky performance status (KPS) scores, tumor sites and surgical resection degrees between the two groups (P>0.05). There were 8 patients with 1p/19q co-deletion and 74 patients without 1p/19q co-deletion; no significant differences in above clinical parameters were noted between the two groups. There were no statistically significant differences in the incidences of bone marrow suppression, digestive tract response and fatigue, disease progression rate, or survival rate between patients from TERTp wild type group and TERTp mutation group, and between patients with 1p/19q co-deletion and patients without 1p/19q co-deletion (P>0.05). No significant differences in above clinical parameters, disease progression rate, and survival rate were noted between patients with C228 mutation and C250 mutation (P>0.05). Conclusion TERTp typing and 1p/19q co-deletion status do not have prognostic value in newly-diagnosed MGMT un-methylated/IDH wild-type GBM patients; patients with TERTp mutations have older age than wild-type patients; patients with C250 mutation trend to have higher survival rate than those with C228 mutation.

Esophageal squamous cell carcinoma(ESCC)is a major histological subtype of esopha-geal cancer with a poor prognosis.Although several serum metabolomic investigations have been reported,ESCC tumor-associated metabolic alterations and predictive biomarkers in sera have not been defined.Here,we enrolled 34 treatment-naive patients with ESCC and collected their pre-and post-esophagectomy sera together with the sera from 34 healthy volunteers for a metabo-lomic survey.Our comprehensive analysis identified ESCC tumor-associated metabolic alterations as represented by a panel of 12 serum metabolites.Notably,postoperative abrosia and parenteral nutrition substantially perturbed the serum metabolome.Furthermore,we performed an examina-tion using sera from carcinogen-induced mice at the dysplasia and ESCC stages and identified three ESCC tumor-associated metabolites conserved between mice and humans.Notably,among these metabolites,the level of pipecolic acid was observed to be progressively increased in mouse sera from dysplasia to cancerization,and it could be used to accurately discriminate between mice at the dysplasia stage and healthy control mice.Furthermore,this metabolite is essential for ESCC cells to restrain oxidative stress-induced DNA damage and cell proliferation arrest.Together,this study revealed a panel of 12 ESCC tumor-associated serum metabolites with potential for monitor-ing therapeutic efficacy and disease relapse,presented evidence for refining parenteral nutrition composition,and highlighted serum pipecolic acid as an attractive biomarker for predicting ESCC tumorigenesis.

Objective To observe the clinical efficacy of Jiangshabanxia nano-paste on nausea and vomiting in end-stage patients and its effect on the quality-of-life (QOL) in cancer patients. Methods 120 end-stage patients with nausea and vomiting symptoms above grade III were randomly divided into observation group and control group. They were treated with Jiangshabanxia nano-paste and placebo paste respectively. The paste patch was changed every 24 hours and used continuously for 7 days. The nausea and vomiting symptom score, the quality-of-life measurement score and KPS score of cancer patients in the two groups were observed to evaluate the curative effect. Results After 7 days of treatment, the symptom scores of nausea and vomiting in the observation group decreased significantly, the KPS score of the observation group increased, and the effective rate was higher than that in the control group. The score of QOL measurement showed that after treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group decreased, and the score of overall health area increased. After treatment, the score of main symptom areas and other symptom areas (except external dyspnea, diarrhea and economic difficulties) in the observation group was lower than that in the control group, and the scores of overall health area in the observation group were higher than those in the control group. Conclusion Jiangshabanxia nano-paste has a good clinical efficacy nausea and vomiting in end-stage patients, it also can improve the quality of life end-stage cancer patients.
