ABSTRACT

MicroRNAs (miRNAs) are a class of small, single-stranded non-coding RNAs that act as important regulators of gene expression and are involved in a number of important processes in life. A large number of studies have suggested that dysregulation of miRNA expression may be an important part of the mechanism of human tumorigenesis and progression. MiR-155-5p is mainly regarded as an oncomiR that acts on multiple target genes to participate in tumor progression, although it has been suggested to possess cancer growth suppressor effects. In this paper, we summarize the effects of miR-155-5p on cancer cell proliferation, invasion, migration, and drug resistance in various tumor types and elucidate its value as a possible potential marker in assisting diagnosis.

ABSTRACT

OBJECTIVE:To in vestigate the effects of dexmedetomidine (Dex)on SIRT 1/Akt/GSK3β/β-catenin signaling pathway in cerebral injury of sepsis model rats ,and explore the mechanism of its protecitve effect on cerebral injury. METHODS : A total of 80 male SD rats were randomly divided into sham operation group (Sham group ),sepsis group (CLP group ),CLP+Dex group(10 μg/kg Dex),CLP+Dex+Sirtinol group (10 μg/kg Dex+2 μL/100 g SIRT 1 inhibitor sirtinol ),with 20 mice in each group. Two hours before modeling ,CLP+Dex+Sirtinol group was injected with sirtinol via lateral ventricle. Sepsis model was induced by cecal ligation and perforation in each group (in sham group ,only operation was performed but no ligation was performed). At 0,3,6 h after modeling ,CLP+Dex group and CLP+Dex+Sirtinol group were given Dex (10 μg/kg) intraperitoneally,Sham group and CLP group were given constant volume of normal saline intraperitoneally. Cerebral tissue water content,Evans blue (EB)content,apoptosis in cerebral cortex ,the levels of IL- 1β and TNF-α in cerebral tissue as well as the protein expression of SIRT 1,p-Akt,p-GSK3β and β-catenin in hippocampus were detected 24 h after last medication. RESULTS : Compared with Sham group ,cerebral tissue water content ,EB content ,the number of apoptotic cells in cerebral cortex as well as the levels of IL- 1β and TNF-α in cerebral tissue were increased significantly(P<0.05),while the protein expression of SIRT 1, p-Akt,p-GSK3β and β-catenin in hippocampus were decreased significantly (P<0.05). Compared with CLP group ,cerebral tissue water content ,EB content ,the number of apoptotic cells in cerebral cortex as well as the levels of IL- 1β and TNF-α in cerebral tissue were decreased significantly in CLP+Dex group (P<0.05),while the protein expression of SIRT 1,p-Akt,p-GSK3β and β-catenin in hippocampus were increased significantly (P<0.05). Sirtinol could significantly reverse the above-mentioned cerebral protection and factor regulation effects of Dex (P<0.05). CONCLUSIONS :Dex can protect the cerebral tissue of sepsis model rats,which may play an anti-inflammatory and anti-apoptotic role by activating SIRT 1/Akt/GSK3β/β-catenin signaling pathway ,so as to reduce cerebral edema ,protect blood-brain barrier and reduce cerebral injury.

ABSTRACT

OBJECTIVE: To investigate the rationality of TLC identification method (3) of (R,S)-epigoitrin in Isatis indigotica stated in 2015 edition of Chinese Pharmacopeia (partⅠ) (later abbreviated as pharmacopeia), and make some improvements. METHODS: Three batches I. indigotica were collected and prepared into decoction pieces according to the processing method of I. indigotica in pharmacopoeia. TLC identification of (R,S)-goitrin in I. indigotica decoction piece and medicinal material were conducted according to identification method (3) in pharmacopeia (80% ethanol as solvent for sample treatment, ultrasound extraction); the rationality of pharmacopoeia method was investigated. Then the method was improved by changing the extraction solvent and pretreatment method (method one: using water as solvent, ultrasound extraction; method two: soaking in water for 1 h, then adding into methanol, ultrasound extraction; method three: the sample was wetted and then dried, using 80% methanol as solvent, ultrasound extraction) of samples, and the optimal method was verified. According to the optimal method, the TLC identification of (R,S)-goitrin was detected by using chromatographic plates from different manufacturers, under the conditions of low temperature and low humidity (7 ℃, relative humidity 48%) and high temperature and high humidity (35 ℃, relative humidity 75%) respectively,to investigate the durability of the method. RESULTS: According to the method of pharmacopeia, in the chromatograms of decoction pieces, the same color spots appeared at the corresponding chromatographic positions of reference substance, but no corresponding spots appeared in the medicinal material chromatograms. After the samples were treated by three improvement methods, in medicinal material chromatograms, the same color spots appeared in the corresponding chromatographic positions of reference substances. There were single chromatographic spot after medicinal materials were treated with method one, and there were more spots after medicinal materials were treated with method two and three, and method two consumed less time than method three. The results of validation tests and method durability tests  showed that after the treatment of I. indigotica and its decoction pieces according to method two, the same color spots appeared in the corresponding positions of the decoction pieces and the medicinal materials chromatograms as those of the control. CONCLUSIONS: The improved TLC identification method is effective, the chromatographic spots are clear, and the repeatability is good.

ABSTRACT

Objective To evaluate the effects of two fluid therapy methods guided by SVV and CVP re-spectively on intestinal barrier of colon cancer surgery with elderly patients. Methods 50 elderly patients with ASA Ⅱ~Ⅲ level were randomly divided into Group S (fluid therapy guided by SVV) and Group C (convention-al fluid therapy). Each group has 25 cases. Patients in group S were treated under goal-directed fluid infusion strategy with target of 10%≤SVV≤12%. Group C received conventional infusion characterized by monitoring central venous pressure (CVP) and mean arterial pressure (MAP). Fluid volume, surgery time, urine volume, blood loss, exhausting time, post-operative hospitalization days in Group S and Group C were recorded. MAP, HR, CVP, SVV, HCO3- of patients were recorded at the same time before anesthesia (T0), beginning of surgery (T1), one hour after surgery (T2) and ending of surgery (T3) respectively. Venous blood samples were collected at the time points of T0, T1, T2 and T3 to detect DAO and D-lactic acid levels. Results MAP and CVP at time points of T2 and T3 in Group S were obviously lower than that in Group C; total intraoperative fluid volume in Group S was obviously less than that in Group C (P < 0. 05); postoperative exhausting time and hospitalization days in Group S decreased significantly (P < 0.05) and the content of DAO and D-lactic acid in Group S were lower than that in Group C (P < 0.05). Conclusion For elderly patients with colon cancer surgery, fluid thera-py guided by SVV is better than conventional fluid therapy guided by CVP in protecting intestinal barrier.

ABSTRACT

Objective Radical surgery is extensively used in the treatment of lung cancer in elderly patients .This study aimed to investigate the effects of acute hypervolemic hemodilution (AHVHD) on the cognitive function and plasma S100βof elderly people following radical surgery for lung cancer . Methods A total of 112 lung cancer patients treated by radical surgery were equally randomized to an AHVHD and a non-AHVHD control group .Using the Mini-Mental State Examination scale ( MMSE) , we evaluated the cognitive function of the patients .We made comparisons between the two groups in the cerebral oxygen metabolism indexes and plasma S100βlevels at T0(immediately after anesthesia induction), T1(15 min after hemodilution), T2(60 min after hemodilution), T3(60 min before the end of surgery ) and T4 ( at the end of surgery ) as well as MMSE scores before and after operation . Results At T1 , T2, T3, and T4, the values of jugular venous oxygen saturation in the AHVHD group were (75.1 ±4.3), (78.5 ±3.1), (79.1 ± 4.4), and (79.6 ±2.8) %, respectively, with time-dependent decreases in Da-jvO2 and cerebral oxygen extraction , and significantly higher than that at T0 (P<0.05) and those in the control group ([63.4 ±2.0], [63.9 ±1.8], [64.2 ±3.0], and [64.7 ±3.2]%) (P<0.05).The levels of plasma S100βat T1, T2, T3, and T4 were remarkably lower in the AHVHD group ([0.53 ±0.04], [0.52 ±0.07], [0.51 ±0.06], and [0.50 ±0.08] μg/L) than in the control ([0.64 ±0.06], [0.64 ±0.04], [0.65 ±0.05], and [0.67 ±0.06] μg/L), with statistically significant differences between the two groups at the same time point (P<0.05).At 1, 3, 5, and 7 days after surgery, the MMSE scores were markedly higher in the AHVHD group (24.3 ±1.7, 26.5 ±1.9, 27.8 ±1.3, and 28.1 ±1.0) than in the control (21.1 ±1.6, 24.0 ±2.1, 25.9 ±1.8, and 26.4 ±1.7) (P<0.05). Conclusion AHVHD can significantly improve cognitive function and reduce plasma S 100βin elderly patients following radical surgery for lung cancer , which may be related to cerebral oxygen metabolism .

ABSTRACT

Neurofeedback, as an alternative treatment method of behavioral medicine, is a technique which translates the electroencephalogram (EEG) signals to styles as sounds or animation to help people understand their own physical status and learn to enhance or suppress certain EEG signals to regulate their own brain functions after several repeated trainings. This paper develops a neurofeedback system on the foundation of brain-computer interface technique. The EEG features are extracted through real-time signal process and then translated to feedback information. Two feedback screens are designed for relaxation training and attention training individually. The veracity and feasibility of the neurofeedback system are validated through system simulation and preliminary experiment.
