ABSTRACT
Objective:To evaluate the efficacy of esketamine combined with fascia iliaca compartment-subarachnoid block in optimizing anesthesia in elderly patients undergoing hip fracture surgery.Methods:Sixty-two American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ elderly patients of either sex, aged 60-85 yr, with body mass index of 18.5-30.0 kg/m 2, were divided into 2 groups ( n=31 each) using a random number table method: fascia iliaca compartment-subarachnoid block group (FS group) and esketamine combined with fascia iliaca compartment-subarachnoid block group (ES group). In FS group, patients underwent ultrasound-guided fascia iliaca compartment block at 30 min before the operation of subarachnoid anesthesia on the surgical side. In ES group, esketamine 0.25 mg/kg was intravenously administered at 5 min before skin incision based on the fascia iliaca compartment-subarachnoid block. Patient-controlled intravenous analgesia was used for postoperative analgesia, and tramadol 1 mg/kg was intravenously given for rescue analgesia when numerical rating scale score > 4. The pressing times of patient-controlled analgesic pump, the number of rescue analgesia and consumption of tramadol were recorded within 48 h after operation. The occurrence of postoperative adverse reactions (respiratory depression, nausea and vomiting, dizziness, drowsiness, pruritus, illusion, nightmares) was recorded. Results:Compared with FS group, the consumption of postoperative tramadol was significantly decreased, and the pressing times of patient-controlled analgesic pump and the number of rescue analgesia were reduced in ES group ( P<0.05). There were no significant differences in the incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:Combination of esketamine with fascia iliaca compartment-subarachnoid block for hip fracture surgery can raise postoperative analgesia and optimize clinical management strategies in elderly patients.
ABSTRACT
Objective To investigate the effect of miR-218-1-3p on the proliferation,cycle,and apoptosis of A549 cells in non-small-cell lung cancer.Methods miR-218-1-3p was transfected into non-small cell lung cancer A549 cells by LipofectamineTM 2000 Reagent,and the expression of miR-218-3p was detected by real-time PC R.Invasion and migration were assayed using the Transwell method.The effect of miR-218-1-3p on the proliferation of A549 cells was assayed by the MTS method.Changes in the cell cycle and apoptosis of A549 cells transfected with miR-218-1-3p was detected by flow cytometry.Changes in indicators related to cell proliferation,cycle,and apoptosis were detected by fluorescence quantitative PCR.Results Compared to the control group,the cell proliferation of A549 cells was significantly inhibited (P ＜ 0.05) and the proportion of cells in the S and G2-M phases was significantly decreased when miR-218-1-3p was up-regulated.In addition,compared with the control group,the early apoptotic rate was significantly increased by up-regulating miR-218-1-3p.We further detected indicators related to cell proliferation,cycle,and apoptosis and found that CYCLIN-D1 and BCL-2 were significantly downregulated.Conclusion miR-218-1-3p may inhibit proliferation,induce cell cycle arrest,and promote cell apoptosis of non-small cell lung cancer A549 cells by regulating CYCLIN-D 1 and BCL-2.
ABSTRACT
BACKGROUND: Cerebrovascular disease often causes dysfunction of the brain nerve, and nerve cel apoptosis is the important factor of cerebral nerve dysfunction. The excessive expression of c-fos can block the transduction of intracelular signal so that producing some apoptosis-promoting factors, which involve in nerve cel apoptosis process after ischemia injury of brain. Bcl-2 is an inhibited factor. It might to be the key to treat ischemic cerebrovascular disease by inhibiting or reducing the apoptosis of nerve cels after ischemia injury. OBJECTIVE: To investigate the therapeutic effect and mechanism of the Total Flavone of Hawthorn Leaf on chronic cerebral ischemia rats. METHODS: A total of 72 healthy male Sprague-Dawley rats were randomly divided into sham surgery group, model group, Total Flavone of Hawthorn Leaf group and ginkgo leaf group. Permanent bilateral carotid artery ligation was used to prepare chronic cerebral ischemia model in the model group, Total Flavone of Hawthorn Leaf group and ginkgo leaf group. Total Flavone of Hawthorn Leaf group and ginkgo leaf group respectively received 140 mg/kg Total Flavone of Hawthorn Leaf and 12.3 mg/kg ginkgo leaf intragastricaly for 36 days from 36 days after model induction. Model group and sham surgery group received 3.5 mL/kg physiological saline intragastricaly. RESULTS AND CONCLUSION: Compared with the model group, the expression of c-fos protein significantly deceased in the Total Flavone of Hawthorn Leaf group (P 0.05). These data indicated that the protective effect of Total Flavone of Hawthorn Leaf on chronic cerebral ischemia was associated with its inhibition of neuronal apoptosis. Its mechanism of anti-apoptosis might be associated with up-regulating expression of Bcl-2, down-regulating expression of c-fos and decreasing Ca2+ content in brain.
