It is necessary to study further syndrome differentiation based treatment of peripheral vascular disease. In order to improve the clinical effect and reduce the rate of amputation, early diagnosis and early intervention are important. Meanwhile, treatment of Chinese medicine should be combined with necessary surgical intervention. It should be important to supplement some details about blood stasis syndrome and activating blood and dissolving stasis therapy of peripheral vascular disease. The application of various Chinese medicine external therapies should not be ignored, especially promoting granulation and wound healing therapy.

Late-onset hypogonadism (LOH) is a clinical and bio-chemical syndrome associated with advancing age in males and seriously affects the quality of life of some of the patients. A classical therapeutic option for LOH is testosterone supplementary treatment (TST). Its effectiveness has been verified, whereas its long-term safety remains to be further evaluated. With deeper insights into LOH, many new therapeutic strategies have been proposed, which include the treatments with gonadotropins, testosterone precursors (such as dehydroepiandrosterone [DHEA]), non-aromatizable androgens (such as dihydrotestosterone [DHT]), antiestrogens (such as aromatase inhibitors and estrogen receptor antagonists), and Chinese medicine. Meanwhile, studies on the transplantation of Leydig stem cells, selective androgen receptor modulators (SARMs), and selective estrogen receptor beta (ERbeta) agonists have shed new light on the treatment of LOH.

Objective To establish a pretreatment method which is applicable to the determination of strontium(Sr)in toothpaste by flame atomic absorption spectrometry.Methods The pretreatment was performed by using digestion pot technique, with lanthanum nitrate as the anti-interference agent.Flame atomic absorption spectrometry was used in this study,the parameters of digestion temperature and the results of two pretreatment methods were compared.Results The toothpaste sample was digested completely by using digestion pot technique with little examined elements lost during digestion.Time-saving and pollution-free were seen in the test.The detection limit of this method was 0.02?g/ml,and the RSDs were 0.98%-3.01%.The recovery rate was at the range of 94.7%-110%.No significant difference was seen between these two pretreatment methods.Conclusion This method has advantages of high sensitivity and precision in the determination of strontium in toothpaste by flame atomic absorption spectrometry,so it can be employed in various laboratories.

Objective: To study the influence of total salvianolic acid(TSA) on the renal interstitial fibrosis caused by unilateral ureteral obstruction (UUO) in rats. Methods: Forty healthy Sprague-Dawley rats were randomly divided into 4 groups: the UUO group, sham operation group, angiotensin-converting enzyme inhibitor ( ACEI)-treated group (positive control), and TSA-treated group. The rats in UUO group and sham-operation group received gastric gavage with normal saline for 8 days before operation; rats in ACEI-treated group and TSA-treated group received ACEI (6 mg/kg by daily gastric gavage for 8 days) and TSA (20 mg/kg by daily gastric gavage for 8 days), respectively. All rats were killed 7 days after operation and the expression of transforming growth factor-β 1 (TGF-β1) was detected by immunohistochemical method. The dynamic histological changes of renal interstitial tissues were observed by H-E and Masson staining. Results: TGF-β1 expression in TSA-treated (1.38 ± 0.26) and ACEI-treated (1.38 ± 0.26) groups was significantly lower than that in UUO group (P < 0.05). TSA obviously reduced TGF-β1 expression and collagen deposition in the renal interstitial tissues and improved the renal pathological changes in UUO rats. Conclusion: TSA can evidently inhibit UUO-induced renal interstitial fibros is in rats, which might be related with the down regulation of TGF-β1 expression.

Objective: To study the inhibitory effect of rosmarinic acid on xanthine oxidase. Methods: Xanthine oxidase (0.1 U/ml) was incubated with xanthine (1 mmol/L for determining formation of uric acid; 50 μmol/L for determining superoxide anions) in the presence of 20, 40 and 60 μg/ml rosmarinic acid or allopurinol as positive control. The formation of uric acid was determined by automatic biochemical analyzer 5 min after reaction and the production of superoxide anions was measured by Nitro Blue Btetrazolium (NBT) reduction. HL-60 cells (1 ml, 2×105/ml) were pretreated with xanthine (100 μl, 6 mol/L) and xanthine oxidase (100 μl, 0.1 U/ml), then rosmarinic acid (500 μg/ml) or allopurinol (1 μg/ ml, as positive control) (Annexin V-PI kit) was added to determine the cell apoptosis rate. HL-60 cells (1 ml, 2×105/ml) were also pretreated with xanthine (100 μl, 6 mol/L) and xanthine oxidase (100 μl, 0.1 U/ml), then rosmarinic acid (500 μg/ml) or SOD (100 U/ml, as positive control) (cell cycle method) was added to determine the cell apoptosis rate. Results: Rosmarinic acid obviously inhibited the production of uric acid and superoxide anion-induced reaction in NBT assay, with their IC50 being 56 μg/ml and 21 μg/ml, respectively. The rates of apoptosis inhibition by rosmarinic acid were both over 40% by Annexin V-PI kit and cell cycle method. Conclusion: Rosmarinic acid is a competitive inhibitor of xanthine oxidase.

Objective: To study the inhibition of xanthine oxidase by renierol extracted from South China Sea sponge and study the influence of renierol on hyperuricemia in mice. Methods: After extracted from South China Sea sponge, renierol (20, 40, 60 μg/ml) was added to a system containing xanthine oxidase (0. 1 μ/ml) and xanthine (50 μmol/ml); allopurinol (1 μg/ml) was also addded to the system as positive control. The 5 min-fomation of superoxide anions was used to determine the activity of xanthine oxidase (Nitro Blue Btetrazolium reduction). Renierol (20, 40, 60 μg/ml) was added to 25°C pre-heated pyrogallol autoxidation to observe its eliminating effect on free radicals through determining the absorbance rate at 420 nm wavelength. Potassium oxonate, a uricase inhibitor, was used to induce hyperuricemia in mice and the mice were then treated with oral renierol (10, 20, 30 mg · kg-1) or allopurinol (2 mg/kg) as positive control. The decrease of serum uric acid induced by renierol was determined by automatic biochemical analyzer. Results: Renierol was demonstrated to be a competitive inhibitor of xanthine oxidase in vitro , with its IC50 value being 1.36 μg · ml-1. It also decreased uric acid in vivo. Conclusion: Renierol can decrease serum uric acid through inhibiting the xanthine oxidase.
