Objective To study the therapeutic effects and mechanism of Sodium Fendate(SF) on rats with severe acute pancreatitis(SAP) induced by L-arginine. Method A total of 60 adult SD rats were randomly and e-qually divided into control group, SAP group and SF group, with 20 rats in each group. The rat model of SAP wes established by injecting 2.5 g/kg L-arginine at a dose of intraperitoneally twice at an interval of 1 hour, and rats in SAP group and SF groups were administrated intraperitoneally with 20% L-arginine solution(2.5 g/kg×2) twice at an interval of 1 hour; rats in control group were injected intraperitoneally with the same volume of physiological saline twice alone.At 5 minutes after L-arginine administration,rats in SF group were injected with SF solution (100 mg/kg, qd×3 d) via the tail vein, and rats in the other two groups received a sham injection of the same volume of physiological saline alone. The characteristics of ascites, the pathological changes of pancreatic tissue and the serum levels of amylase(AMY), endothelin-l(ET-1), tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) and the contents of malonaldehyde (MDA), suede dismutase (SOD), reduced glutathioue (GSH) of pan-creatic tissue of rats and prognosis were compared at 72 hours after L-arginine administration. Measurement data were evaluated by oue-way ANOVA, and numeration data were assessed by Fisher' s exact test. P<0.05 was considered statistically significant. Results Compared with control group,at 72 hours after L-arginine administra-tion,rats in SAP group presented characteristically histopathological changes of SAP with significantly higher serum levels of AMY, ET-1, TNF-α, IL-6 and MDA of pancreatic tissue[(9715.5±301.3) IU/L vs. (729.2±134.2) IU/L;(25.32±3.67) ng/L vs. (14.32±2.69) ng/L;(102.95±11.24) ng/L vs. (38.62±3.87) ng/L; (538.63±9.53) ng/L vs. (186.35±1.19) ng/L;(34.8±3.9) mol/kg vs. (8.1±2.1) mol/kg, all P< 0.01], and lower GSH and SOD in the pancreatic tissue[(7.1±0.6) mg/kg vs. (16.9±1.9) mg/kg; (6423± 1978) kU/kg vs. (29905+2945) kU/kg,both P<0.01].Compared with SAPmodel group,at 72 hours after ad-ministration of L-arginiue, the pathological lesions of SAP in rats of SF group were significantly alleviated with lower pathological scores (P<0.05), lower serum levels of AMY, ET-1 ,TNF-α,IL-6 and MDA in the pancreatic tissue [(8104.6±149.9) IU/L vs. (9715.5±301.3) IU/L; (20.26±5.86) ng/L vs. (25.32±3.67) ng/L; (84.19±15.14) ng/L vs. (102.95±11.24) ng/L;(458±5.37) mol/kg vs. (538.63±9.53) rig/L;(28.3±2.5) moL/kg vs. (34.8±3.9) mol/kg,all P<0.05], and higher SOD and GSH in the pancreatic tissue[(8.5 ±1.4) mg/kg vs. (7.1±0.6) mg/kg;(10 316±2810) kU/kg vs. (6423±1978) kU/kg, both P<0.05].At 72 hours the death rate in SF group was lower than that in SAP group,but the difference had no significance (P= 0.2.5). Conclusions SF can scavenge oxygen-derived free radicals, upgrade the contents of SOD and GSH of pancreatic tissue,decrease the levels of serum proinflammatory cytokines and ET-1, ameliorate the pathological le-sions of pancreatic tissue in rats,and has the capability of decreasing death rate, so it possesses a distinct advantage for the treatment of SAP.

Objective To investigate the effect of valsartan and amlodipine on urinary microalbumin in elderly hypertensive patients. Methods 100 elderly patients with hypertension treated in our hospital from May 2015 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group received oral valsartan, and the patients in the experimental group were treated with valsartan and amlodipine. The treatment time of the experimental group and the control group was 12 weeks. The clinical indexes of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the experimental group and the control group did not have obvious adverse reactions. There were 2 cases of headache in the experimental group, 1 cases of vertigo, and 2 cases of vertigo in the control group. However, there was no significant difference in the incidence of adverse reactions between the experimental group and the control group, and there was no statistical significance. The antihypertensive effect of the experimental group was significantly higher than that of the control group, with statistical significance (P<0.05). After treatment, the urinary microalbumin in the experimental group and the control group was significantly lower than that in the treatment group, and the level of microalbuminuria in the experimental group was lower than that in the control group, with statistical significance (P<0.05). Conclusion The clinical effect of treatment of elderly patients with hypertension better combined with valsartan and amlodipine, antihypertensive effect is stronger, can significantly improve the patient's urinary albumin, with further clinical promotion and application significance.

Object To investigate the therapeutic effects and mechanism of traditional Chinese compound decoction of Radix Curcumae (RC), Rhizoma Sparganii (RS), and Rhizoma Zedoariae (RZ) (DRRR) on liver fibrosis in rats induced by carbon tetrachloride (CCl 4). Methods Fifty Wistar rats were randomly divided into four groups: group A was healthy control (n=8), group B was model rats of liver fibrosis induced by CCl 4 (n=14), group C and D were treated with DRRR after the liver fibrosis in rats induced by CCl 4 four weeks later (n=14). B, C, and D groups were injected subcutaneously with CCl 4; C and D groups were administrated with DRRR 0.6 and 1.2 g/100 g, once per day. After administration of DRRR four weeks all rats were sacrificed, their blood and liver were harvested for further examination. The effect of DRRR was explored by the expressions and sites of transforming growth factor-beta 1 (TGF-? 1), Smad3 and Smad7 in liver tissues by immunohistochemical staining. The liver function, serum hyaluronic acid (HA), and liver histopathology were also examined by biochemsitry, RIA, HE, and Van Gieson stainings respectively. Results To compare with model group, in rats that received DRRR, the expressions of TGF-? 1 and Smad3 were significantly decreased, while the expression of Smad7 was obviously increased in the livers (P

Objective:To observe the efficacy and safety of Qingpeng ointment in the prevention and treatment of chemotherapeutic phlebitis. Methods:Totally 72 patients with non-small cell lung cancer undergoing chemotherapy after pneumonectomy were randomly divided into control and observation groups. The control group was treated with the conventional therapy to prevent phlebitis, and on the basis of conrentional therapy the observation group was treated with Qingpeng ointment at the injection site and along with the vein be-fore the chemotherapy, at the beginning of the chemotherapy, during the chemotherapy and after the chemotherapy in the same day and on the next day. The treatment course was 3 days. The incidence of phlebitis, hierarchical cases, VAS score and pain duration between the groups were compared, and the adverse drug reactions were observed. Results:The pain degree and duration induced by phlebitis showed no significant differences between the groups(P>0. 05), while the pain degree and duration in the observation group were de-creased when compared with those in the control group. The incidence of phlebitis in the observation group was obviously lower than that in the control group with statistically significant difference (P <0. 05). No adverse reactions were found with the external use of Qingpeng ointment. Conclusion:Qingpeng ointment has certain efficacy with high safety in the prevention of tumor-chemotherapeutic phlebitis, which can improve patients’ compliance, and is worthy of promoted application in clinics.
