Distribution of Traditional Chinese Medicine syndromes in diabetic kidney disease chronic kidney disease 1-5: a correlation study.

OBJECTIVE: To analyze the distribution of Traditional Chinese medicine (TCM) syndromes in patients with diabetic kidney disease (DKD) and its related factors. METHODS: We enrolled 435 patients with DKD, who were not undergoing dialysis, admitted to the Department of Nephrology, First Medical Center, Chinese PLA General Hospital from April 2020 to August 2021. Analysis of their TCM syndromes and related factors was carried out. RESULTS: The 435 patients included 109, 117, 86, and 123 chronic kidney disease (CKD) 1-2, CKD3, CKD4, and CKD5 cases, respectively. With the progression of CKD1-5, the proportion of Yin deficiency and dry heat syndrome, and that of Qi and Yin deficiency syndrome showed a downward trend, whereas the proportion of spleen-kidney Yang deficiency, blood deficiency, blood stasis, water stagnation, and phlegm turbidity syndromes showed an upward trend; the differences were statistically significant (P < 0.05). Multivariate logistic regression analysis showed that Yin deficiency and dry heat syndrome was positively correlated with hemoglobin [odds ratio (OR) = 1.022, P = 0.005], albumin (OR = 1.058, P = 0.006), and estimated glomerular filtration rate (eGFR) (OR = 1.020, P < 0.001) but negatively correlated with male sex (OR = 0.277, P = 0.004). Qi and Yin deficiency syndrome was positively correlated with albumin (OR = 1.056, P < 0.001) and eGFR (OR = 1.008, P = 0.022) but negatively correlated with age (OR = 0.977, P = 0.023). Liver-kidney Yin deficiency syndrome was positively correlated with age (OR = 1.028, P = 0.021) and glycosylated hemoglobin (OR = 1.223, P = 0.007) but negatively correlated with total cholesterol (OR = 0.792, P = 0.006). Spleen-kidney Yang deficiency syndrome was negatively correlated with hemoglobin (OR = 0.977, P < 0.001), albumin (OR = 0.891, P < 0.001), and eGFR (OR = 0.978, P < 0.001) but positively correlated with high density lipoprotein (OR = 3.376, P = 0.001). CONCLUSION: With CKD1-5 progression, TCM syndromes changed from Yin deficiency and dry heat syndrome to syndrome of deficiency of both Qi and Yin, liver-kidney Yin, and spleen-kidney Yang deficiency syndromes. TCM syndromes were correlated with laboratory test results.

Noninvasive identificational diagnosis of diabetic nephropathy and non-diabetic renal disease based on clinical characteristics of Traditional Chinese Medicine symptom pattern and conventional medicine.

OBJECTIVE: To study the clinical characteristics relating to differential diagnosis of diabetic nephropathy (DN) and non-diabetic renal disease (NDRD). METHODS: The subjects were patients with type 2 diabetes mellitus (T2DM) complicated with chronic kidney disease (CKD). Western medical history data and Traditional Chinese Medicine (TCM) symptom pattern were collected, and logistic regression was used to analyze. RESULTS: Blood deficiency pattern [odds ratio () = 2.269, 0.017] and stagnation pattern ( = 1.999, 0.041) are independently related to DN. CONCLUSIONS: TCM factors blood deficiency pattern and stagnation pattern are relating to differential diagnosis of DN and NDRD.

Dynamic Analysis of Kidney Function and Its Correlation with Nutritional Indicators in a Large Sample of Hospitalized Elderly Patients.

BACKGROUND The aim of this study was to analyze changes in kidney function and its correlation with nutritional metabolism indicators in hospitalized elderly patients in a large medical center over the past 7 years. MATERIAL AND METHODS The renal function of patients over 60 years old in the Chinese PLA General Hospital in 2008, 2011, and 2014 were comparatively analyzed. The hemoglobin, serum albumin, triglycerides, cholesterol, uric acid, and urea nitrogen data were collected and used as the nutritional metabolism indicators. In addition, the correlation between these indicators and the eGFR was analyzed. RESULTS The numbers of patients who received kidney function assessments in the 3 years were 15 752, 23 539, and 49 828; their mean ages were 69.97±6.99, 69.51±7.11, and 69.45±7.74 years. The median values of serum creatinine were 75.4, 76.5, and 77.5 µmol/L in the men and 59.6, 60.7, and 62.1 µmol/L in the women. The eGFR in both sexes demonstrated a gradual decreasing trend over the 3 years. According to the CKD staging method, analysis of the different percentages of eGFR intervals in the patients showed that the percentages of the 3 groups with an eGFR lower than 60 mL/min/1.73 m² exhibited a rising trend annually. Correlational analysis of the nutritional indicators showed that the correlations between Hb, ALB, TG, TC, Ur, and BUN with an eGFR lower than 60 mL/min/1.73 m² were 0.582, 0.780, 1.219, 1.364, 2.180, and 3.677, respectively. CONCLUSIONS Serum creatinine showed a gradually increasing trend over the 3 study years. The CKD-EPI equation calculation results showed that the eGFR in elderly people of both sexes gradually decreased. Reduction of hemoglobin and albumin was a risk factor for decreased kidney function, while increases in uric acid and blood lipids affected the progression of renal insufficiency.

Effective suppression of fibronectin synthesis by retrovirus delivered shRNA in rat cardiac fibroblasts.

Extracellular matrix overexpression is a common final pathway that leads to ventricular remodeling. Fibronectin plays a pivotal role in this progress. In the work presented here, we explored the possibility of direct inhibition of fibronectin synthesis in rat cardiac fibroblasts by small interference RNA (siRNA). We found that siRNA could successfully suppress the fibronectin overexpression stimulated by angiotensin II. To overcome the limitations of plasmid-based siRNA, we subcloned the H1 promoter into pLXIN, a commercially available retroviral vector. We found that H1 promoter worked very well to form the small hairpin RNA (shRNA) on the retroviral vector, and the fibronectin expression was dramatically down regulated by shRNA. We think the retroviral shRNA delivery system that we have constructed may have potential roles in treating ventricular remodeling.
