Objective To investigate the expression profiles of microRNA in early esophageal squamous cancer and normal esophageal tissues and verify the significantly different expression miRNAs , further to study the effects on proliferation of EC109. Methods The microarray assay was performed to analyze miRNA expression profiles in three pairs of early esophageal squamous cancer and the corresponding normal esophageal tissues. Quantitative real-time polymerase chain reaction (qRT-PCR) was used in another 38 pairs samples to further verify the differentially expressed miRNAs . Three verified miRNAs ( miR-29a, miR-221 and miR-222) mimics were transfected into EC109 respectively and CCK8 method was used to study the effect of cell proliferation in each miRNA. Results Microarray technique selected 53 miRNAs that differentially expressed in early esophageal squamous cancer and normal esophageal tissues , 32 miRNAs were up-regulated and 21 miRNAs were down-regulated. qRT-PCR verified that miR-29a was significantly down-regulated (P < 0.05) and miR-221, miR-222 were significantly up-regulated (P < 0.05) in early esophageal squamous cancer tissue. Over-expression of miR-29a could significantly inhibit the proliferation of EC109 (P < 0.05) whereas over-expression of miR-221 or miR-222 could both significantly promote the proliferation of EC109 (P < 0.05). Conclusion There was significant difference of miRNAs expression between early esophageal squamous cancer and normal esophageal tissues, and the differentially expressed miRNAs could be used as new biomarkers for early diagnosis of esophageal squamous cancer.

This article was aimed to study anti-inflammatory effects of petroleum ether extract from Citrullus lanatus vine (PEECLV) and explore the mechanism. The methods of ear swelling with xylene, increasing of peritoneal capil-lary permeability, and paw edema with egg albumin were used in the establishment of mice models, respectively. Granuloma with cotton pellet, and paw edema with carrageenan were used in the establishment of rat models, re-spectively. Observation was made on anti-inflammatory effects of PEECLV. The content of nitrous oxide (NO) and nitric oxide synthase (NOS), as well as the level of TNF-α and IL-1β in blood serum were measured among granu-loma with cotton pellet rat models. Contents of malondialdehyde (MDA), prostaglandin E2 (PGE2), 5-HT, histamine (His), and protein in inflammatory exudates from the paw edema with carrageenan rat model, as well as contents of NO and NOS in blood serum, and activity of superoxide dismutase (SOD) were measured in order to study the possi-ble anti-inflammatory effects. The results showed that PEECLV can suppress the ear swelling with xylene, the in-creasing of peritoneal capillary permeability, and the paw edema with egg albumin in mice, as well as granuloma with cotton pellet, paw edema with carrageenan in rats. It had anti-inflammatory effects at different degrees. The content of NO and NOS, as well as the level of TNF-α and IL-1β in blood serum were reduced in granuloma with cotton pellet rat models. The content of MDA, PGE2, 5-HT, His, and protein content were reduced in inflammatory exudates from the paw edema with carrageenan rat model. The increasing of NO and NOS in blood serum was inhib-ited. And the activity of SOD was increased. It was concluded that PEECLV had certain anti-inflammatory effects. Its mechanism may be related to the influence of the production of inflammatory mediators and antioxidant.

Objective:Acute kidney injury (AKI) is one of the common complications in critically ill septic patients, which is associated with increased risks of death, cardiovascular events, and chronic renal dysfunction. The duration of AKI and the renal function recovery status after AKI onset can affect the patient prognosis. Nevertheless, it remains controversial whether early recovery status after AKI is closely related to the prognosis in patients with sepsis-associated AKI (SA-AKI). In addition, early prediction of renal function recovery after AKI is beneficial to individualized treatment decision-making and prevention of severe complications, thus improving the prognosis. At present, there is limited clinical information on how to identify SA-AKI patients at high risk of unrecovered renal function at an early stage. The study aims to investigate the association between early recovery status after SA-AKI, identify risk factors for unrecovered renal function, and to improve patients ' quality of life.Methods:We retrospectively analyzed clinical data of septic patients who were admitted to the intensive care unit (ICU) and developed AKI within the first 48 hours after ICU admission in the Second Xiangya Hospital and the Third Xiangya Hospital of Central South University from January 2015 to March 2017. Sepsis was defined based on the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). AKI was diagnosed and staged according to the 2012 Kidney Disease:Improving Global Outcomes (KDIGO) guideline. SA-AKI patients were assigned into 3 groups including a complete recovery group, a partial recovery group, and an unrecovered group based on recovery status at Day 7 after the diagnosis of AKI. Patients ' baseline characteristics were collected, including demographics, comorbidities, clinical and laboratory examination information at ICU admission, and treatment within the first 24 hours. The primary outcome of the study was the composite of death and chronic dialysis at 90 days, and secondary outcomes included length of stay in the ICU, length of stay in the hospital, and persistent renal dysfunction. Multivariate regression analysis was performed to evaluate the prognostic value of early recovery status after AKI and to determine the risk factors for unrecovered renal function after AKI. Sensitivity analysis was conducted in patients who still stayed in hospital on Day 7 after AKI diagnosis, patients without premorbid chronic kidney disease, and patients with AKI Stage 2 to 3.Results:A total of 553 SA-AKI patients were enrolled, of whom 251 (45.4%), 73 (13.2%), and 229 (41.4%) were categorized as the complete recovery group, the partial recovery group, and the unrecovered group, respectively. Compared with the complete or partial recovery group, the unrecovered group had a higher incidence of 90-day mortality (unrecovered vs partial recovery or complete recovery: 64.2% vs 26.0% or 22.7%; P<0.001) and 90-day composite outcome (unrecovered vs partial recovery or complete recovery:65.1%vs 27.4%or 22.7%;P<0.001). The unrecovered group also had a shorter length of stay in the hospital and a larger proportion of progression into persistent renal dysfunction than the other 2 groups. After adjustment for potential confounders, patients in the unrecovered group were at an increased risk of 90-day mortality (HR=3.50, 95% CI 2.47 to 4.96, P<0.001) and 90-day composite outcome (OR=5.55, 95%CI 3.43 to 8.98, P<0.001) when compared with patients in the complete recovery group, but patients in the partial recovery group had no significant difference (P>0.05). Male sex, congestive heart failure, pneumonia, respiratory rate>20 beats per minute, anemia, hyperbilirubinemia, need for mechanical ventilation, and AKI Stage 3 were identified as independent risk factors for unrecovered renal function after AKI. The sensitivity analysis further supported that unrecovered renal function after AKI remained an independent predictor for 90-day mortality and composite outcome in the subgroups. Conclusion:The early recovery status after AKI is closely associated with poor prognosis in critically ill patients with SA-AKI. Unrecovered renal function within the first 7 days after AKI diagnosis is an independent predictor for 90-day mortality and composite outcome. Male sex, congestive heart failure, pneumonia, tachypnea, anemia, hyperbilirubinemia, respiratory failure, and severe AKI are risk factors for unrecovered renal function after AKI. Therefore, timely assessment for the renal function in the early phase after AKI diagnosis is essential for SA-AKI patients. Furthermore, patients with unrecovered renal function after AKI need additional management in the hospital, including rigorous monitoring, avoidance of nephrotoxin, and continuous assessment for the renal function, and after discharge, including more frequent follow-up, regular outpatient consultation, and prevention of long-term adverse events.

Objective:To investigate the alteration of glymphatic system based on diffusion tensor image-analysis along the perivascular space(DTI-ALPS)in bipolar disorder Ⅰ(BD-Ⅰ).Methods:A total of 44 BD-Ⅰ patients(BD-Ⅰ group) admitted to the Affiliated Brain Hospital of Guangzhou Medical University from January 2012 to December 2017 were selected.In addition, totally 30 healthy controls (HC group) were recruited. The diffusion tensor image data were analyzed retrospectively, and along the perivascular space (ALPS) index was calculated. Hamilton anxiety scale (HAMA), 17-item Hamilton depression rating scale (HAMD-17), Young mania rating scale (YMRS) and global assessment function (GAF) were used to evaluate the severity of anxiety, depression, mania and social function respectively. SPSS 25.0 software was used for t-test, Z-test and chi-square test, and the differences in clinical data and DTI-ALPS index between the two groups were compared. The partial correlation test was used to analyze the correlations between DTI-ALPS index and the clinical indicators such as HAMA, HAMD-17, YMRS and GAF. Results:The DTI-ALPS indexes in left(1.69±0.17), right(1.44±0.15) and bilateral cerebral hemispheres(1.56±0.15) of BD-Ⅰ group were lower than those in HC group ((1.71±0.15), (1.46±0.13) and (1.58±0.12)), but the differences were not statistically significant ( t=-0.441, -0.545, -0.556, all P>0.05). After controlling for gender, age, years of education and course of disease, there were significant negative correlations between bilateral average DTI-ALPS index and somatic anxiety ( r=-0.334, P=0.038), as well as between right DTI-ALPS index and somatic anxiety( r=-0.349, P=0.030) in BD-Ⅰ group. Conclusion:The dysfunction of cerebral glymphatic system is not obvious in BD-Ⅰ patients, but their anxiety may be related to dysfunction cerebral glymphatic system.
