Objective To investigate the efficacy of high-dose ambroxol in elderly patients with aspiration pneumonias. Methods Totally 62 patients aged 65 years and over with aspiration pneumonia were enrolled into 2 groups:conventional-dose group intravenously given ambroxol 60 mg/d (n=30) and high-dose group received 270 mg/d (n=32).The times of remission and fever disappearance,rate of adverse effects,average duration of hospitalization,rates of mortality and recurrence within 2 months were observed. Results There were no significant differences in clinical charecteristics between the two groups.The times of remission and fever disappear ance and average duration of hospitalization were lower in high-dose group than in conventional-dose group [(3.2±0.6)d,(54.2±19.5)h,(12.7±4.1) d vs.(3.8±1.1)d,(66.5±18.4)h,(13.5±3.1)d,t=2.11,2.36,2.04,all P<0.05].No differences were found in rates of mortality and recurrence within 2 months between the two groups (6.3%,3.1% vs.10.0%,13.3%,x2=0.01,0.87,both P>0.05).Adverse effects did not appear in the two dose groups. Conclusions High-dose ambroxol is efficient and safe for aspiration pneumonia in elderly patients.

One of the causes of the high cost of pharmaceuticals and the major obstacles to rapidly assessing the bioavailability and risk of a chemical is the lack of experimental model systems. A new pre-treatment technology, in vitro bionic digestion was designed for metal analysis in Lianhua Qingwen capsule. The capsule was digested on 37 degrees C under the acidity of the stomach or intestine, and with the inorganic and organic compounds (including digestive enzymes) found in the stomach or intestine, and then the chyme was obtained. Being similar to the biomembrane between the gastrointestinal tract and blood vessels, monolayer liposome was used as biomembrane model Affinity-monolayer liposome metals (AMLMs) and water-soluble metals were used for metal speciation analysis in the capsule. Based on the concentration of AMLMs, the main absorption site of trace metals was proposed. The metal total contents or the concentration of AMLMs in the capsule were compared to the nutritional requirements, daily permissible dose and heavy metal total contents from the "import and export of medicinal plants and preparation of green industry state standards". The metal concentrations in the capsule were within the safety baseline levels for human consumption. After in vitro bionic digestion, most of trace metals were absorbed mainly in intestine. The concentration of As, Cd, Pb was 0.38, 0.07, 1.60 mg x kg(-1), respectively, far less than the permissible dose from the "import and export of medicinal plants and preparation of green industry state standards".

Objective To investigate the radiobiological effects of radiation with different dose rates on human nasopharyngeal carcinoma cell line CNE-2 treated with or without a poly ADP-ribose polymerase (PARP) inhibitor,olaparib.Methods The concentration of olaparib used to treat cells equaled to the inhibition concentration IC10 of olaparib to CNE-2 cells.The CNE-2 cells were divided into acute radiotherapy (RT) group,fractionated radiotherapy (FRT) group,olaparib + RT group,and olaparib + FRT group.All groups were exposed to radiation of 0,1,2,3,5,7,and 10 Gy at a dose rate of 3 Gy/min.The delivery time for each dose point was 4 min in RT and 30 min in FRT.The colony forming assay was used to evaluate the survival of CNE-2 cells at each dose point.The multi-target,single-hit model was used to fit the cell survival curves and the parameters,D0,Dq,and SF2,were calculated.At dose points of 0.1,and 2 Gy,western blot was used to determine the expression of PARP-1 in the RT group and the FRT group and γH2AX in each group.Immunofluorescence was used to evaluate the γH2AX focus formation.A single factor analysis of variance was used to compare the 4 groups,and two two compared with SNK-q test.Results The IC10 value of olaparib to CNE-2 cells was 4.0 μmoL/L.At dose points of 1 and 2 Gy,the PARP-1 expression was significantly higher in the FRT group than in the RT group (P=0.029,0.022),while the γH2AX focus number was significantly smaller in the FRT group than in the other three groups (all P<0.05);compared with the RT group,the D0,Dq,and SF2 values in the FRT group were increased by 11.67%,15.78%,and 23.61%,respectively;compared with the FRT group,the D0,Dq,and SF2 values in the Olaparib+ FRT group decreased by 11.19%,6.44%,and 13.26%,respectively;there were no significant differences in above indices between the RT group,the Olaparib+RT group,and the Olaparib+FRT group.Conclusions For the same radiation dose,fractionation reduces the relative dose rate and weakens the radiobiological effects.lowdose olaparib can compromise the single strand break repair induced by the decline of the relative dose rate in a fractionated irradiation mode,which promotes the formation of double-strand break and improves the radiobiological effects.

To evaluate the efficacy and safety of acupuncture combined with traction therapy for lumbar disc herniation, providing the basis for future research strategies. Randomized control trials. (RCT) of acupuncture combined with traction therapy for lumber disc herniation at home and abroad from 2000 to 2013 were searched, analysis and evaluation of literature and strength of evidence were based on the principles and methods of Evidence-based Medicine. The total effective rate and curative rate were considered as primary outcome measures; pain improvement, quality of life, relapse rate and adverse effects were considered as secondary outcome measures. Seventeen RCTs were identified, Meta-analysis showed that (1) total effective rate and curative rate: acupuncture combined with traction therapy was better than single therapy (acupuncture or traction); (2) pain improvement: acupuncture combined with traction therapy was better than traction therapy; (3) relapse rate: current evidence could not support the conclusion that acupuncture combined with traction therapy was better than traction therapy. Acupuncture combined with traction therapy for lumbar disc herniation was effective. However, the included studies were with high risk of bias, important outcome measures such as quality of life, relapse rate and adverse effects were not found in most of the studies. Current evidence has not yet been able to fully reflect acupuncture combined with traction therapy for lumbar disc herniation is better than single therapy, so more RCTs of higher quality are needed to further confirm its efficacy and safety.

This study aimed to observe changes in the hydrogen sulfide (H2S) system in the blood and liver tissue of rats with hepatic cirrhosis at different stages by studying the effect of H2S on the course of hyperdynamic circulation in rats with hepatic cirrhosis.H2S concentration in the blood from the portal vein and inferior vena cava of hepatic cirrhosis rat model induced with carbon tetrachloride was detected on the 15th,30th,and 52nd day.The expression of cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) protein,and CBS and CSE mRNA in the liver was detected by immunohistochemistry and reverse transcriptase polymerase chain reaction (RT-PCR),respectively.The results indicated that H2S concentration in the blood from the portal vein and inferior vena cava of rats with hepatic cirrhosis was significantly lower than that in the control group.H2S was gradually decreased with the development of the disease and significantly lower in the blood from portal vein than in the blood of inferior vena cava at the mid-stage and the late stage groups.The expression levels of CBS and CSE protein,and CBS and CSE mRNA in the livers with hepatic cirrhosis at different stages were all higher than those in the control group,and the expression gradually increased with the development of the disease.The expression of CBS was lower than CSE in the same stages.The results indicated that the CSE mRNA was expressed predominantly in the cirrhosis groups as compared with CBS rnRNA.Among experimental rats,the H2S system has an important effect on the occurrence and development of hyperdynamic circulation in rats with hepatic cirrhosis.This finding adds to the literature by demonstrating that H2S protects vascular remodelling in the liver,and that CSE is indispensable in this process.
