Xiatianwu tablet is based on the theory of traditional Chinese medicine (TCM), combined with modern TCM pharmacology and selected 33 famous traditional Chinese crude drugs to compose. Its recipe helps cure rheumatism, relax tendons, promote blood circulation to relieve pain, et al. Although Xiatianwu tablets are widely applied to clinical remedy such as rheumatic arthritis, lumbar disc hernia, osteoarthritis and so on, there is no report about its application in fracture. This article is to observe the efficacy of compound Xiatianwu tablets in elderly patients with osteoporotic distal radius fractures and its impact on the wrist function and complications. 180 elderly patients with osteoporotic distal radius fractures, from January 2011 to June 2014, were divided into observation group and control group by the method of random number table, each group had 90 cases. The control group were gave Caltrate D after manipulative reduction and plaster immobilization, observation group were treated with compound Xiatianwu tablets in the basis of the control group. Efficacy, wrist function and complication rates were observed in two groups after treatment. The excellent and good rate was 95.56% in observation group better than 77.78% in control group, the difference was statistically significant (χ2 = 4.712, P < 0.05). The complication rate in observation group was significantly lower compared with the control group (P < 0.05). This study shows that compound Xiatianwu tablets can improve the efficacy in elderly patients with osteoporotic distal radius fractures, reduce the incidence of complications and relieve the pain of patients which plays a significant role in improving the quality of life.

The effect of astaxanthin on N(Ω)-nitro-L-arginine methyl ester (L-NAME) induced preeclampsia disease rats was investigated. Thirty pregnant Sprague-Dawley rats were randomly divided into three groups (n = 10): blank group, L-NAME group and astaxanthin group. From day 5 to 20, astaxanthin group rats were treated with astaxanthin (25 mg x kg(-1) x d(-1) x bw(-1)) from pregnancy (day 5). To establish the preeclamptic rat model, L-NAME group and astaxanthin group rats were injected with L-NAME (125 mg x kg(-1) x d(-1) x bw(-1)) from days 10-20 of pregnancy. The blood pressure and urine protein were recorded. Serum of each group was collected and malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide synthase (NOS) activities were analyzed. Pathological changes were observed with HE stain. The expression of NF-κB (nuclear factor kappa B), ROCK II (Rho-associated protein kinase II), HO-1 (heme oxygenase-1) and Caspase 3 were analyzed with immunohistochemistry. L-NAME induced typical preeclampsia symptoms, such as the increased blood pressure, urinary protein, the content of MDA, etc. Astaxanthin significantly reduced the blood pressure (P < 0.01), the content of MDA (P < 0.05), and increased the activity of SOD (P < 0.05) of preeclampsia rats. The urinary protein, NO, and NOS were also decreased. HE stain revealed that after treated with astaxanthin, the thickness of basilal membrane was improved and the content of trophoblast cells and spiral arteries was reduced. Immunohistochemistry results revealed that the expressions of NF-κB, ROCK II and Caspase 3 in placenta tissue were effectively decreased, and HO-1 was increased. Results indicated that astaxanthin can improve the preeclampsia symptoms by effectively reducing the oxidative stress and inflammatory damages of preeclampsia. It revealed that astaxanthin may be benefit for prevention and treatment of preeclampsia disease.

Objective To investigate whether pantoprazole (PPZ), a proton pump inhibitor,could reverse the transmember pH gradient by inhibiting vacuolar H+-ATPase so as to increase the sensitivity of human gastric adenocarcinoma cell line SGC7901 to antitumor drugs and to evaluate the optimal time of drug administration, dosage of PPZ and the possible mechanism. Methods Western blotting and immunofluorescent staining were used to determine the expression and intracellular distribution of vacuolar H+-ATPase in human gastric adenocarcinoma cell line SGC7901 with or without PPZ pretreatment. 2', 7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein, acetoxymethyl ester (BCECF-AM) fluorescent probe was used to measure the intracellular pH value of human gastric adenocarcinoma cell line SGC7901 which pretreated with different dose and time of PPI. Methyl thiazolyl tetrazolium (MTT) assay and annexin V-fluorescent isothiocyanate-propidium iodide double staining were performed to evaluate the cytotoxic effects and apoptosis of cells treated with antitumor drugs combined with PPZ. Adriamycin (ADR) was used as probe to estimate drug accumulation and retention with PPZ pretreatment. Results After 24 hours, the expression of vacuolar H+-ATPase in cells pretreated with PPZ of 10 μg/ml (1.19±0.03) or 100 μg/ml (0. 70±0.03) was significantly lower than that in blank control (1.53±0. 05), but this expression was increased by pretreatment with PPZ of 1 μg/ml (2.29 +0.06, P<0.05). The inhibitory effects of PPZ (10 μg/ml) on vacuolar H+-ATPase was observed at 6 hours (0.32±0.02)and 12 hours (0. 13±0.02). And it could alter the intracellular distribution of vacuolar H+-ATPase at 24-hours. The intracellular pH value in cells pretreated with PPZ of 10 μg/ml (7.44±0. 09 ) or 100 μg/ml (7.31 ± 0. 06) was significantly decreased in comparison with untreated cells (7.51±0.05, P< 0. 01). After administration of anti-tumor drugs, the viability in SGC7901 cells pretreated with PPZ for 24 hours (58.71%±1.18 %) was significantly lower than that in cells untreated with PPZ (74. 33% ± 1.77%, P<0.05), while thetotal and early apoptotic rates in former cells(80.81% ±1. 16% and 77.52 %±1.13 %, respectively) were significantly higher than those in later cells (26. 42%±1.19% and 23. 18% ±0.92%,respectively,P < 0. 01). And the ADR releasing index in cells treated with PPZ (20, 50 and 100 μg/ml) for 24 hours was obviously lower than that in the blank control (0. 164±0. 013, 0. 162±0.015, 0. 152±0. 012 vs 0. 277±0. 011, respectively, P<0. 01). Conclusion The sensitivity of human gastric adenocarcinoma cell line to antitumor drugs may be increased by pretreatment with PPZ.
