ABSTRACT
Objective:To investigate the hippocampal subfield volumes before and after taking hydrochloric donepezil in patients with mild Alzheimer's disease (AD). Methods:From January, 2017 to June, 2018, 25 mild AD patients accepted hydrochloric donepezil (treatment group), 25 patients accepted placebo (placebo group) and 25 age- and gender-matched healthy old people (control group) were scanned with magnetic resonance imaging (MRI) under 3D-T1 TFE sequence before and after a six-month treatment, and the automated segmentation of the hippocampus subfields was fulfilled with FreeSurfer and the hippocampus subfield volumes were compared, while the patients were assessed with Mini-Mental State Examination (MMSE). Results:Compared with the control group, the volumes of left CA1， CA2-3 and CA4-DG, and right CA1 and CA2-3 were reduced in patients before treatment (t > 2.294, P < 0.05). The volume of left CA4-DG increased in the treatment group compared with that of the placebo group after treatment (t = 2.196, P < 0.05), and the volume of bilateral CA1 and CA2-3 tended to increase but not significantly (t < 1.888, P > 0.065). The MMSE score was more in the treatment group than in the placebo group after treatment (t = 2.764, P < 0.05). Conclusion:The association with asymmetric atrophy in the hippocampal subfields has been found in mild AD patients, especially in left CA4-DG, which may be used as a valuable marker for diagnosis and evaluation for treatment at early stage.
ABSTRACT
Objective: To discuss the clinical efficacy of modified Da Chengqitang by enema in treatment of postoperative inflammatory intestinal obstruction (EPISBO) after the operation and its effect on inflammatory factors, gastrointestinal motility and intestinal barrier function. Method: One hundred and six patients were randomly divided into control group (52 cases) and observation group (54 cases) by random number table. Patients in both groups were given fasting for solids and liquids, gastrointestinal decompression, maintaining water and electrolyte balance, nutritional support and other basic therapies. Patients in control group were given somatostatin for injection for continuous micro-pumping, 0.003 5 mg·h-1·kg-1, dexamethasone acetate tablets, 2.5-5 mg/time, 2 time/days. Patients with concurrent infection got ceftazidime for injection, 30-100 mg·kg-1, 2-3 intravenous drips. In addition to the therapy of control group, patients in observation group were also given modified Da Chengqitang, 125 mL/time, 2 times/days. A course of treatment was 5 days. Time of remission of abdominal distention, recovery of exhaust gas, bowel sounds and diet, defecation, hospitalization and transitional surgery were recorded. And main gastrointestinal symptoms and signs were scored. And levels of serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP), vasoactive intestinal peptide (VIP), gastrin, motilin, diamine oxidase and D lactic acid were detected. Result: After treatment, according to rank sum test analysis, the clinical efficacy in observation group was better than that in control group (PPPPα, hs-CRP, VIP, DAO, D-lactic acid and scores of main gastrointestinal symptoms and signs were all lower than those in control group (PPConclusion: In addition of routine therapy of western medicine, modified Dachengqi Tang had effects in resisting inflammation, regulating gastrointestinal hormones, and protecting intestinal barrier function, so can improve gastrointestinal motility, alleviate symptoms, shorten the course of disease and improve the clinical efficacy.
