ABSTRACT
Objective To investigate the efficacy of intravenous antioxidants therapy in treating moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP).Methods Pubmed,Embase,Cochrane library and CNKI databases for all randomized control trials published before March 18st,2016 manually was searched by computer.Data on AP associated mortality and length of stay (LOS) were collected.The quality of the trials included was assessed by the Cochrane systematic review method.Results Fifteen trials with data of 620 patients were eligible for final inclusion.Among the 15 trials,detailed randomization for grouping was clearly described in 5 studies and obvious bias was observed in 1 study.Three studies had obvious biases considering whether outcome assessment was blinded,outcome data was incomplete and outcome report was selective.No other apparent bias was found.Statistical analysis showed that compared with control group,intravenous antioxidants administration did not significantly reduce mortality (12.1 vs 9.7,RD=-0.02,95％ CI-0.08～-0.03,P=0.44;RR=0.83.95％ CI0.51～ 1.34,P=0.44),but could shorten LOS (MD=-2.02;95％ CI-4.00～-0.05;P=0.04).Conclusions Intravenous antioxidants could greatly shorten LOS of patients with MSAP and SAP.
ABSTRACT
OBJECTIVE:To investigate the effectiveness and economics of 10 mg/d rosuvastatin and 20 mg/d atorvastatin in the treatment of hyperlipidemia (HLP). METHODS:The information of 180 HLP patients selected from Tianmen Municipal First People's Hospital during Mar. 2015-Feb. 2016 were divided into group A and B according to medication regimen,with 90 cases in each group. Group A was given Atorvastatin calcium tablet 20 mg,qd;group B was given Rosuvastatin calcium tablet 10 mg,qd. Treatment course of 2 groups lasted for 8 weeks. Blood lipid indexes before and after treatment,lipid-lowering efficacy,the rate of qualified blood lipid and the occurrence of ADR after treatment were compared between 2 groups. Cost-effectiveness analysis was adopted for economic evaluation. RESULTS:Before treatment,there was no statistical significance in the levels of blood lipid in-dexes between 2 groups (P>0.05). After treatment,TC and LDL-C levels of 2 groups were significantly lower than before treat-ment,and those of group B were significantly lower than those of group A,with statistical significance(P0.05). The costs of group A and B were 488.32,436.24 yuan,and cost-effectiveness ratios were 5.63,4.46;incremental cost-effectiveness ratio was -4.69. The plan of group B had cost-effective-ness advantage. The results of cost-effectiveness analysis were supported by sensitivity analysis. CONCLUSIONS:In the view of short-term efficacy,10 mg/d rosuvastatin plan is better than 20 mg/d atorvastatin plan in lowering lipid and has cost-effectiveness advantage,and both have similar safety.
ABSTRACT
Objective To investigate the effect of rapid repeated cold air inhalation stimulation on cold-sensitive chan-nel transient receptor potential ankyrin 1(TRPA1) associated inflammatory cytokines in living lungs .Methods A total of 20 male Wistar rats were randomly and evenly divided into 4 groups:cold air inhalation group , warm air inhalation group , TRPA1 channel agonist inhalation group and normal group , respectively . Tracheal intubation was carried out after anesthesia in rats of cold air inhalation group , and the tubes were linked to the air temperature controlled device with the temperature controlled at ( 2 ±1 )℃.The rats of warm air inhalation group were treated in the same way as cold air inhalation group except for the temperature at (36 ±1)℃.The rats of both groups were treated for 3 times, 1 hour each time.There were 12 hour intervals between treatments .The rats of TRPA1 channel agonist inhalation group were treated with atomizing inhalation of 60 mmol/L acrolein at room temperature (24 ±2)℃for 3 times, 1 hour each time.There were 12 hour intervals between two treatments .The rats were sacrificed after the last treatment .The tracheas and left lung tissues of all rats were taken and total RNA was extracted .The mRNA expressions of TRPA1, interleukin 1 beta ( IL-1β), interleukin 5(IL-5),and neutrophil chemoattractant chemokine (CXCL-1/KC)in the rat lungs were detected by real-time quantitative PCR .Results TRPA1 was expressed in rat lung tissues .In the short term cold air inhalation group , the expressions of IL-1β,IL-5 and CXCL-1/KC mRNA in the rat lungs were higher than those of the warm air inhalation or the normal groups .Similar results were also found in the specific TRPA 1 channel positive agonist ( acrolein ) inhalation group . Conclusion In living animals, the TRPA1 channels of the lungs can be activated by short-term cold air(<17℃),which results in the increasing expression of some inflammatory cytokines in lungs .
ABSTRACT
OBJECTIVE:To establish a HPLC method for the quantitative determination of Geniposide in Zhibo mixture.METHODS:The separation of sample was performed on Shim-pack VP-ODS C18 column(150mm?4.6mm,5?m)at a temperature of 25℃.The mobile phase consisted of acetonitrile-water(12∶88)at a flow rate of 1mL?min-1.The detection wavelength was set at 238nm.RESULTS:The linear range of Geniposide was 25～100mg?L-1(r=0.999 7).The average recovery was 99.89%(RSD=0.80%,n=9).CONCLUSION:The method was proved to be sensitive,specific,reproducible and suitable for quality control of Zhibo mixture.
