ObjectiveTo explore the dose-effect relationship and safety of high, medium, and low doses of raw Astragali Radix in the modified Huangqi Chifengtang (MHCD) for treating proteinuria in immunoglobulin A (IgA) nephropathy, and to provide scientific evidence for the clinical use of high-dose Astragali Radix in the treatment of proteinuria in IgA nephropathy. MethodsA total of 120 patients with IgA nephropathy, diagnosed with Qi deficiency and blood stasis combined with wind pathogen and heat toxicity, were randomly divided into a control group and three treatment groups. The control group received telmisartan combined with a Chinese medicine placebo, while the treatment groups were given telmisartan combined with MHCD containing different doses of raw Astragali Radix (60, 30, 15 g). Each group contained 30 patients, and the treatment period was 12 weeks. Changes in 24-hour urinary protein (24 hUTP), traditional Chinese medicine (TCM) syndrome scores, effective rate, and renal function were observed before and after treatment. Safety was assessed by monitoring liver function and blood routine. ResultsAfter 12 weeks of treatment, 24 hUTP significantly decreased in the high, medium, and low-dose groups, as well as the control group (P<0.05, P<0.01). The TCM syndrome scores in the high, medium, and low-dose groups also significantly decreased (P<0.01). Comparisons between groups showed that the 24 hUTP in the high-dose group was significantly lower than in the medium, low-dose, and control groups (P<0.05, P<0.01), and the 24 hUTP in the medium-dose group was significantly lower than in the control group (P<0.05). The TCM syndrome scores in the high and medium-dose groups were significantly lower than in the low-dose and control groups (P<0.05, P<0.01). The total effective rates for proteinuria in the high, medium, low-dose, and control groups were 92.59% (25/27), 85.19% (23/27), 60.71% (17/28), and 57.14% (16/28), respectively. The effective rates in the high and medium-dose groups were significantly higher than in the low-dose and control groups (χ2=13.185, P<0.05, P<0.01). The effective rates for TCM syndrome scores in the high, medium, low-dose, and control groups were 88.89% (24/27), 81.48% (22/27), 71.43% (20/28), and 46.43% (13/28), respectively. The efficacy of TCM syndrome scores in the high and medium-dose groups was significantly higher than in the control group (χ2=14.053, P<0.01). Compared with pre-treatment values, there was no statistically significant difference in eGFR and serum creatinine in the high and medium-dose groups. However, eGFR significantly decreased in the low-dose and control groups after treatment (P<0.05), and serum creatinine levels increased significantly in the control group (P<0.05). No statistically significant differences were observed in urea nitrogen, uric acid, albumin, total cholesterol, triglycerides, liver function, and blood routine before and after treatment in any group. ConclusionThere is a dose-effect relationship in the treatment of IgA nephropathy with high, medium, and low doses of raw Astragali Radix in MHCD. The high-dose group exhibited the best therapeutic effect and good safety profile.

OBJECTIVE To study the effects of Phellodendron amurense polysaccharides (PAP) on improving gouty nephropathy (GN) in rats, and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase (p38 MAPK)/nuclear factor-κB(NF-κB)/tumor necrosis factor-α(TNF-α). METHODS Sixty rats were randomly divided into normal group (water), model group (water), allopurinol group (positive control, 20 mg/kg), PAP high-dose, medium-dose and low-dose groups (100, 50, 25 mg/kg, by raw material) after being stratified by body weight, with 10 rats in each group. Except for the normal group, the other groups were induced to construct GN model by giving 1 500 mg/kg potassium oxazinate and 100 mg/kg adenine intragastrically for 14 days. After modeling, the rats in each group were given relevant medicine/water intragastrically, once a day, for consecutive 28 days. After the last medication, the levels of biochemical parameters related to renal function [uric acid, creatinine (Cr), blood urea nitrogen (BUN), xanthine oxidase (XOD)] were detected in rats, and the histopathological changes in the rat kidney were observed. The protein expressions of monocyte chemoattractant protein-1(MCP-1),TNF-α and interleukin-6(IL-6) as well as the phosphorylation levels of p38 MAPK and NF-κB p65 protein were determined in renal tissue of rats. RESULTS Compared with the normal group, the model group suffered from the dilatation of renal tubules, structural damage to glomeruli, accompanied by inflammatory infiltration and fibrosis; the contents of uric acid, Cr, BUN and XOD, the protein expressions of MCP-1,TNF-α and IL-6 and the phosphorylation levels of p38 MAPK and NF-κB p65 protein were all increased significantly (P<0.05 or P<0.01). Compared with the model group, the pathological symptoms of renal tissue in rats had been improved to varying degrees in different dose groups of PAP; the contents of uric acid, Cr, BUN and XOD, protein expressions of MCP-1, TNF-α and IL-6, the phosphorylation levels of p38 MAPK and NF-κB p65 protein in PAP high-dose and PAP medium-dose groups were all decreased significantly (P<0.05 or P<0.01). CONCLUSIONS PAP exhibits an anti-GN effect, the mechanism of which may be associated with inhibiting the p38 MAPK/NF-κB/TNF-α signaling pathway.

Objective:To explore the effect of family empowerment model on the improvement of swallowing care ability and care preparedness of primary caregivers of first-episode stroke dysphagia patients, further to explore its impact on patients′s wallowing function and life quality.Methods:This study was a randomized controlled study. From January 2021 to December 2022, 80 main caregivers of patients with dysphagia caused by manual stroke admitted to the Department of Acupuncture and Moxibustion, Shenzhen Hospital of Traditional Chinese Medicine were selected as the research objects, and 40 cases in the control group and 40 cases in the observation group were selected by random number table method. The control group were treated with conventional nursing care of first-episode stroke dysphagia patients in the acupuncture and moxibustion Department. On the basis of the conventional care in the control group, the observation group were treated with family empowerment model intervention for 14 days and was followed up for 28 days. Primary caregivers′ swallowing care ability, Caregiver Preparedness Scale (CPS), patients′ swallowing function rate, Swallowing Related Quality of Life (SWALQOL) were used to evaluate the effects before intervention and at the end of intervention.Results:There were 18 males and 19 females primary caregivers in the control group, aged (55.61 ± 7.43) years old. There were 18 males and 21 females primary caregivers in the observation group, aged (58.23 ± 8.22) years old. The swallowing care ability score showed a statistically significant difference between the observation group (143.47 ± 3.96) and the control group (107.74 ± 1.43) ( t=-26.76, P<0.05). After intervention, the caregiver preparedness scale was (26.11 ± 3.81) in the observation group, and (18.35 ± 4.54) in the control group, and the difference was statistically significant ( t=-4.11, P<0.05).The patients′ swallowing function rate and SWALQOL score were respectively 97.44% (38/39) and (91.41 ± 8.08) points in the observation group, and 72.97% (27/37) and (80.33 ± 4.21) points in the control group, and the difference was both statistically significant ( χ2=10.76, t=-2.54, both P<0.05). Conclusions:The implementation of family empowerment model could enhance the swallowing care ability and care preparedness of primary caregivers of the first-episode stroke dysphagia patients, which could further improve patients′ swallowing function and life quality.

BACKGROUND:Olfactory dysfunction is an early biological marker of various diseases.However,the neuroimaging mechanism by which olfactory dysfunction occurs following cerebral small vessel disease is unclear. OBJECTIVE:To explore the different neuroimaging mechanisms of olfactory function regulation in patients with cerebral small vessel disease and Parkinson's disease,and explore the potential application value of olfactory function assessment in patients with cerebral small vessel disease. METHODS:Neuropsychological and olfactory tests,high-resolution structural magnetic resonance and resting-state functional magnetic resonance data were collected in 80 patients with cerebral small vessel disease,44 healthy controls and 29 patients with Parkinson's disease.DPABI,SPM12 and SPSS were used to analyze and compare the amplitude of low frequency fluctuation,regional homogeneity and functional connectivity values between the cerebral small vessel disease,control and Parkinson's disease groups.Correlations between the significantly altered resting-state functional magnetic resonance imaging measures and olfactory and cognitive scores were evaluated. RESULTS AND CONCLUSION:Compared with the control group,low-frequency fluctuation amplitude of the right dorsolateral superior frontal gyrus and the regional homogeneity of the left wedge leaf were significantly reduced in the cerebral small vessel disease and Parkinson's disease groups.The right dorsolateral superior frontal gyrus and the left cuneiform lobe are the seed points.Compared with the Parkinson's disease group,the functional connectivity values of the right anterior cunei,inferior temporal gyrus,anterior central gyrus and dorsolateral superior frontal gyrus,left posterior central gyrus and inferior temporal gyrus were significantly enhanced in the control and cerebral small vessel disease groups.The left cuneiform lobe was the seed point.Compared with the control group,the functional connectivity of the left lingual gyrus was significantly weakened in the cerebral small vessel disease and Parkinson's disease groups.The functional connectivity values of the left middle temporal gyrus and the right posterior central gyrus were enhanced in the control group compared with the cerebral small vessel disease and Parkinson's disease group,and that was enhanced in the cerebral small vessel disease group compared with the Parkinson's disease group.Correlation analysis showed that the olfactory score and cognitive score were positively correlated in the cerebral small vessel disease group,and the regional homogeneity of the left wedge lobe was negatively correlated with the Montreal Cognitive Assessment Scale score,while the functional connectivity of left wedge lobe-left middle temporal gyrus in the Parkinson's disease group was positively correlated with the olfactory recognition score,and the functional connectivity values of the left wedge lobe-left posterior central gyrus and left wedge lobe-left lingual gyrus were positively correlated with the olfactory identification score and the total olfactory score,respectively.The regulation of olfactory function in patients with cerebral small vessel disease has a different neuroimaging mechanism from that of olfactory dysfunction in patients with Parkinson's disease.The olfactory function of patients with cerebral small vessel disease is related to cognitive function.It is speculated that the olfactory function following cerebral small vessel disease is a secondary change of brain dysfunction,while olfactory dysfunction following Parkinson's disease is directly caused by abnormal function of olfactory-related brain areas.Olfactory function assessment in patients with cerebral small vessel disease has potential application in predicting cognitive function.
