ObjectiveTo investigate the clinical effect of Shipiyin combined with diosmin in the treatment of lymphedema with spleen Yang deficiency syndrome(SYDS)after modified radical mastectomy and the specific effect on the function of the affected limb. MethodEighty-two patients with lymphedema with SYDS after modified radical mastectomy from outpatient and inpatient department of breast department and oncology department of the First Affiliated Hospital of Hunan University of Chinese Medicine were randomly divided into an observation group(41 cases) and a control group(41 cases). The control group was given diosmin tablets(0.9 g per time, two times per day)on the basis of conventional treatment,and the observation group was given Shipiyin(one dose per day)on the basis of the control group. The course of treatment was 14 days. The clinical symptoms were observed and the limb circumference,traditional Chinese medicine(TCM) syndrome score,functional assessment of cancer therapy-breast cancer(FACT-B) score,disability of arm, shoulder and hand questionnaire(DASH) score,and joint range of motion were measured to analyze the TCM syndrome therapeutic effect and clinical efficacy. ResultAfter 14 days of treatment, the total effective rate of the observation group was 85.37% (35/41) and that of the control group was 63.41% (26/41) in the TCM symptoms, showing a statistically significant difference (Z=-2.212, P<0.05). In terms of the clinical efficacy, the total effective rate in the observation group was 82.93% (34/41) and that in the control group was 75.61% (31/41), indicating a statistically significant difference (Z=-2.061, P<0.05). Compared with the situations before treatment, the scores of clinical symptoms such as the swelling of the upper limb, pain, sense of heaviness, stuffiness, fatigue, fullness, tightness, and skin keratosis and pruritus in the two groups were significantly lowered (P<0.01) after treatment. Compared with the control group, the observation group could better improve the swelling and fullness(P<0.01),as well as the feeling of pain,heaviness,stuffiness,fatigue,tightness,skin keratosis and pruritus (P<0.05)of the upper limbs of patients. The affected limb circumference, TCM syndrome score, and DASH score decreased significantly, while the FACT-B score and upper limb joint range of motion increased significantly in the two groups after treatment (P<0.01). Compared with the control group, the observation group showed significantly reduced limb circumference at 10 cm proximal to the elbow striae, lowered TCM syndrome score, elevated FACT-B score(P<0.05), decreased DASH score and improved range of motion of the upper limb joint (P<0.01) after treatment. ConclusionShipiyin combined with diosmin has better clinical efficacy in the treatment of lymphedema with SYDS after modified radical mastectomy than diosmin alone,which can better improve the clinical symptoms,signs,quality of life and limb functional activity of patients. This provides a new clinical program for the treatment of lymphedema after breast cancer surgery with integrated Chinese and western medicine.

As bioflavonoids have a strong affinity to bind with albumin, it is plausible that they may have the ability to displace the diuretic furosemide bound to albumin. In this study we sought to verify this hypothesis by examining the effect of the co-administration of a bioflavonoid with furosemide on the diuretic activity of the latter. Diosmin is a bioflavonoids type of plant chemical found mainly in citrus fruits.For this purpose, we analyzed bioflavonoids by their ability to bind to human serum albumin (HAS) using an in silico method and found that diosmin had a higher affinity to albumin than furosemide. Subsequently, we investigated the effect of the co-administration of diosmin with furosemide on the diuretic activity of the latter in mice.Our results showed that the combination did not produce any significant change in the diuretic activity of furosemide; however, after 3 hours of treatment, the urine volume of the mice that received diosmin along with frusemide was greater than that of mice administered only the same dose of furosemide. There was no significant difference in urine volume between the two groups at the end of 24 hours. A similar trend of increased levels at 3 hours in the combination group and absence of any difference at 24 hours was noted in the case of the urine concentrations of Na+, K+, and 2 Cl Our findings indicate that co-administration of diosmin increased the immediate diuretic effect of furosemide for the first few hours and that this effect subsides within 24 hrs. Therefore, this combination should be used with care, especially during the first few hours of administration

PURPOSE: Kidney stones (nephrolithiasis) are a widespread disease. Thus, blocking stone formation and finding new therapeutic methods is an important area of study. Diosmin (a major component of the bile) is known to have antioxidant as well as renoprotective effects. The present investigation aimed to evaluate the effect of diosmin on renal tissue protection in rats with ethylene glycol-induced nephrolithiasis. MATERIALS AND METHODS: The rats were randomly divided into three groups. Group one (control) did not receive any treatments. In groups two and three, nephrolithiasis was induced by 2.5% (V/V) ethylene glycol + 2.5% (W/V) ammonium chloride (2 mL/d). The second and the third groups received distilled water or diosmin (80 mg/kg/d) by gavage for 21 days. RESULTS: Stereological estimation of the renal structures revealed that the average volume of calcium oxalate (CaOx) in the nephrolithiasis+diosmin rats was -63% less than in the rats with untreated nephrolithiasis (p<0.01). The volume of the glomeruli, proximal and distal convoluted tubules, Henle's loop, collecting ducts, and vessels was reduced -32% to 58% after the induction of nephrolithiasis (p<0.001). In the nephrolithiasis+diosmin rats, on average, -70% to 96% of the glomeruli, proximal convoluted tubules, Henle's loop collecting ducts, and vessels remained intact (p<0.01). Degeneration of the cortical tissue was 5-fold that of the medulla. In the nephrolithiasis+diosmin rats, degeneration in the renal cortical tissue and medulla was reduced -70% and 44%, respectively, compared with that in the untreated nephrolithiasis group (p<0.01). CONCLUSIONS: Diosmin reduces CaOx deposition and the degeneration of glomeruli and tubules in a rat model of nephrolithiasis.
