Objective:To investigate the effect of "simulated Chinese medicine nursing clinic" teaching on syndrome differentiation ability among nursing students and the teaching effect of this method.Methods:A total of 325 students were randomly divided into conventional teaching group with 163 students (receiving conventional nursing teaching) and real situational teaching group with 162 students (receiving "simulated Chinese medicine nursing nursing clinic" teaching at the same time). A self-made questionnaire for syndrome differentiation-based nursing ability, assessment scores of traditional Chinese medicine nursing theories and skills, and a teaching satisfaction questionnaire were used for evaluation.Results:After intervention, the real situational teaching group (the treatment group and the experience group) had significantly higher socres of syndrome differentiation-based nursing ability (mastery of four diagnostic methods, diagnosis of syndromes, analysis of syndromes, determination of nursing principles, and development of nursing regimens) than the conventional teaching group (the treatment group and the conventional teaching group: 8.97±1.00/8.47±1.20/8.33±1.06/8.30±1.26/7.89±1.13 and 7.96±1.14/7.29±1.36/7.14±1.18/7.39±1.30/7.26±1.18, P<0.05; the experience group and the conventional teaching group: 8.39±1.10/8.17±1.15/8.07±1.06/7.97±1.26/7.73±1.38 and 7.96±1.14/7.29±1.36/7.14±1.18/7.39±1.30/7.26±1.18, P<0.05). The real situational teaching group had a significantly higher overall degree of satisfaction with teaching than the conventional teaching group [160 (97.6%) and 150 (92.0%), P<0.05]. Conclusions:The "simulated Chinese medicine nursing clinic" teaching program effectively enhances the thinking of syndrome differientiation and related abilities for nursing, improves the learning effect of traditional Chinese medicine nursing theories and skills, and increases the learning interest in traditional Chinese medicine nursing among nursing students.

Objective To explore the effects of fecal microbiota transplantation(FMT)on oxalate metabolism and renal protection in rats fed a high oxalate diet.Methods Twenty-four male SD rats were randomly divided into four groups:SC,SC+FMT,OD+PBS and OD+FMT.The SC group was set as the control group and was fed standard rat chow.The OD+PBS group and OD+FMT group were fed a diet containing 5%oxalate.Starting from day 14,the OD+PBS group,OD+FMT group and SC+FMT group received intragastric administration of PBS solution or filtered faecal microbiota solution from guinea pigs for 7 consecutive days.The 24-hour urine,feces,and venous serum of the rats were collected from the rats of all groups to determine the gut microbiota and biochemical markers.Real-time quantitative PCR and immunohistochemistry were conducted on the rat kidneys to detect the expression of renin,ACE,and OPN.Results The fecal microbiota transplantation altered the gut microbiota of rats.The gut microbiota of the SC+FMT group deviated from that of the SC group and showed increased similarity to that of the guinea pigs.Compared to the OD+PBS group,the OD+FMT group exhibited significant reductions in the urinary oxalate,urinary urea,uric acid,urinary creatinine,serum urea nitrogen/creati-nine,and serum uric acid.Furthermore,after FMT treatment,the OD+FMT group exhibited reduced upregulation of renin mRNA expression and restored downregulation of OPN mRNA expression compared to the OD+PBS group;similar results were obtained from immunohistochemistry.Conclusion Fecal microbiome trans-plantation activated the microbial network in the rat gut,particularly the oxalate-degrading bacteria represented by Muribaculaceae.The kidney injury induced by high oxalate was partially restored by the microbiota network's degradation of oxalate,indicating the protective effect of fecal microbiota transplantation on the rat kidneys.

Objective:To explore the effect of fecal microbiota transplantation (FMT) on the formation of renal calcium oxalate crystals in SD rats induced by oxalate mixed diet.Methods:Six male guinea pigs were fed with standard guinea pig chow for 1 month and then given a 5% oxalate diet for 14 d. The guinea pigs on the standard chow were labeled as the standard chow guinea pig (GSC group) and those on the high oxalate diet for 14 d were labeled as the guinea pig group on the high oxalate diet (GOD group). The feces of guinea pigs in the GSC and GOD groups were collected using metabolic cages. Twenty-four male SD rats were randomly divided into standard chow (SC) group, oxalate diet(OD)+ phosphate buffered saline gavage group (OD+ PBS group), OD+ FMT group and SC+ FMT group. Among them, the SC group and SC+ FMT group were fed with standard chow. The OD+ PBS group and OD+ FMT group were fed with 5% oxalate content chow. The OD+ FMT and SC+ FMT groups were given GOD group guinea pig fecal filtrate gavage for 7 days. The 24 h urine and feces of rats in each group were collected, and the intestinal microbiota of rats and guinea pigs were detected by 16sRNA detection. The urinary oxalate excretion was detected by high performance liquid chromatography. The rats and kidneys were weighed and the renal index was calculated. HE staining was used to observe the histological morphological changes of rat kidney tissue, the calcium oxalate crystal deposition in renal tissues was detected by Pizzolato staining.Results:The relative abundance of bacteria from a total of 11 families, including Muribaculaceae family and Bifidobacteriaceae family, was significantly increased in the intestinal tract of guinea pigs (GOD) from the high oxalate diet group compared to guinea pigs (GSC) from the standard chow group. The microbial diversity of the intestinal microbiota of the rats in the OD+ PBS group was reduced compared to the SC group, and the microbial diversity of the intestinal microbiota of the rats in the OD+ FMT group was restored compared to the OD+ PBS group. When given a standard chow, the intestinal microbiota of rats receiving FMT deviated from that of normal rats and was more similar to that of guinea pigs fed a high oxalate diet. In the OD+ FMT group, bacteria from a total of 18 families, including Muribaculaceae family, Erysipelotrichaceae family and Bifidobacteriaceae family, were significantly enriched, and FMT activated the intestinal microbial network represented by bacteria from Muribaculaceae family. The renal index of rats in the OD+ PBS group was significantly increased compared to the SC group (7.63±0.67 vs. 6.12±0.53, P<0.05), whereas the renal index of rats in the OD+ FMT group was significantly decreased in comparison to the OD+ PBS group (6.53±0.64 vs. 7.63±0.67, P<0.05). Urinary oxalate excretion of rats in the SC group, the OD+ PBS group, and the OD+ FMT group were (0.61±0.05), (0.89±0.04) and (0.72±0.04) μmol/ml, respectively. In the rats of the SC group no calcium oxalate crystals were seen in the kidney (0 score) and more calcium oxalate crystals were detected in the OD+ PBS group (4.83±0.41 score). The OD+ FMT group showed significantly lower calcium oxalate crystallization scores (3.17 ± 0.75 score, P<0.01) compared to the OD+ PBS group. Conclusions:FMT activated the microbial network represented by bacteria from the family Muribaculaceae in the rat intestine, significantly reduced urinary oxalate excretion and renal calcium oxalate crystal deposition in rats on a high oxalate diet.

Ferroptosis is a new type of programmed cell death that is closely associated with the pathophysiological process of ischemic stroke. Ferroptosis inhibitors can improve neurological function and provide neuroprotection after cerebral ischemia. Therefore, the role of ferroptosis in ischemic stroke and the regulation of ferroptosis to intervene in the occurrence and development of ischemic stroke have become a research hotspot. This article reviews the molecular mechanism and potential therapeutic targets of ferroptosis during ischemic stroke, hoping to provide new perspectives for the treatment of ischemic stroke.

Objective:To explore the relationship between serum matrix metalloproteinase-8 (MMP-8), myeloperoxidase (MPO), human cytomegalovirus (HCMV) infection and the type of carotid atherosclerosis in patients with ischemic cerebrovascular disease (ICVD).Methods:From February 2017 to May 2019, 90 patients with ischemic cerebrovascular disease diagnosed by Peking University Medical Rehabilitation Hospital were selected as study group and 90 healthy adult persons who underwent health checkup as control group, and the study group was divided into non-stable plaque type group (30 cases) and stable plaque type group (30 cases) according to the ultrasonic imaging data and referring to the type of carotid plaque of the patients. The patients whose plaque property were between the two groups were were enrolled as the middle type group (30 cases). The relationship between human cytomegalovirus PP65 antigen (HCMV-PP65) in the serum, MMP-8, MPO and peripheral blood white blood cells and carotid atherosclerotic plaque in patients with ischemic cerebrovascular disease was analyzed.Results:The serum MMP-8, MPO level and HCMV-PP65 positive rate in the 3 study groups were significantly higher than that of the control group ( P<0.05), and the serum MMP-8 in different plaque types groups was significantly higher in the study group and the control group than in the control group. The higher the level of MPO and the positive rate of HCMV-PP65, the higher the serum MMP-8 and MPO level in the middle plaque type group, and the positive rate of HCMV-PP65 in the middle plaque type group was higher than that of the stable plaque group and the unstable plaque group ( P<0.05). Conclusions:The serum MMP-8, the MPO level and the HCMV infection are related to the unstable type of the carotid atherosclerosis plaque in the patients with the ischemic cerebrovascular disease, and the recognition of the carotid atherosclerosis is improved; it is an important link to control the severity of patients with ischemic cerebrovascular disease and to take timely and effective prevention and treatment measures.
