ABSTRACT

OBJECTIVE To study the effects of the Mongolian medicine Sugemule-4 on the metabolism of insomnia rats, and to preliminarily explore its possible mechanisms for improving insomnia. METHODS The rat model of chronic stress insomnia was established by tail clipping stimulation and intraperitoneal injection of p-chlorophenyl alanine solution. Twenty-four male rats were randomly divided into the normal group, model group, diazepam group (positive control, 0.92 mg/kg), and Sugemule-4 group (5.2 g/kg), with 6 rats in each group. Since the 7th day of tail clipping stimulation, the Sugemule-4 group and diazepam group began to be intragastrically administered with relevant medicine; the normal group and model group were intragastrically administered with an equal volume of distilled water, once a day, for 14 consecutive days. The learning and memory abilities of rats were tested using a water maze experiment, and the non-invasive sleep activity monitoring system was used to monitor the 24- hour sleep time of rats. A metabolomics study was conducted on rat serum and hippocampal tissue by using ultra-high-performance liquid chromatography-tandem mass spectrometry. The multivariate statistical analysis method was adopted to analyze the differential metabolites in serum and hippocampal tissue of rats, and screen for differential metabolites and metabolic pathways among those groups. RESULTS Compared with the normal group, the escape latency of rats in the model group was significantly increased, the times of crossing platforms were significantly reduced, and the percentage of average 24-hour sleep time was significantly reduced (P<0.05). Compared with the model group, the levels of the above indicators were significantly reversed in the diazepam group and Sugemule-4 group (P<0.05). Metabolomics studies found that a total of 9 differential metabolites were identified in rat serum and hippocampal tissue, including 5-hydroxyindoleacetic acid, canine urate, canine urinary quinolinic acid, 5-hydroxytryptamine, phenol sulfate, 1-carboxyethyltyrosine, 3-(4-hydroxyphenyl) lactate, N-acetyl tyrosine, tyrosine and phenol sulfate, mainly involving 2 metabolic pathways of tryptophan and tyrosine.CONCLUSIONS Sugemule-4 can improve the sleep time and behavioral performance of insomnia rats, and its mechanism may be associated with affecting amino acid metabolic pathways such as tryptophan and tyrosine.

ABSTRACT

Objective To investigate the therapeutic efficacy of combining Kangfuxin solution with compound Bingpengsan on patients with diabetes mellitus complicated with pressure sores. Methods Fifty-two diabetes mellitus patients complicated with pressure sores admitted in Department of Emergency in the PLA 155th Central Hospital were divided into observation group and control group by lot method,26 cases in each group. Observation group was treated by combining Kangfuxin solution with compound Bingpengsan,the control group was given Mepliex application therapy,they all had change of dressing once a day. After treatment for 20 days,the therapeutic efficacy of pressure sore,healing time and frequency of changing dressing were observed. Results The total effective rate in observation group was significantly higher than that of control group〔96.1%(25/26)vs. 80.6%(21/26),P<0.05〕, in the observation group,the pressure sore healing time was significantly shorter than that of the control group(day:Ⅱstage:9.5±1.7 vs. 13.0±2.1,Ⅲstage:13.1±3.1 vs. 18.1±5.1,Ⅳstage:15.3±3.7 vs. 19.6±5.9,all P<0.05)and the number of times of changing dressing was significantly reduced compared with that of control group (times:Ⅱ stage:16.39±1.89 vs. 19.32±2.26,Ⅲ stage:19.56±2.52 vs. 22.36±2.69,Ⅳ stage:23.54±2.86 vs. 26.47±3.96,all P<0.05). Conclusion The Kangfuxin solution combined with compound Bingpengsan for treatment of deep pressure ulcers in patients with diabetes mellitus has significant effect,its cure rate is relatively high,the pressure sore healing time is reduced and the patients' suffering is alleviated.
