OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

CONCLUSIONIn clinical treatment for intractable pediatric mycoplasma pneumonia, Chinese medicine combined Western medicine plus scientific and systematic nursing showed more obvious advantages with significant efficacy, which was worth spreading.

Objective To observe the radiosensitization effect of Aidi injection on human lung adenocarcinoma A549 cells, and to analyze its possible mechanism.Methods ① A549 cells were treated with different concentrations of Aidi injection (1.875, 3.75, 7.5, 15, 30, 60 mg/mL) for 24 hours, and in the mean time, a blank control group was set up; the effect of Aidi injection on lung adenocarcinoma A549 cells proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay, and the 10% cell growth inhibitor concentration (IC10) was calculated. ② The experiments were divided into blank control, Aidi control, radiation and Aidi pretreatment groups. The Aidi control group was incubated for 24 hours by Aidi injection IC10; the radiotherapy group was given X-ray irradiation of 4 Gy followed by incubation for 24 hours; the Aidi pretreatment group was incubated for 24 hours by Aidi injection IC10 and then given X-ray irradiation of 4 Gy; the blank control group received equal volume of normal saline and was incubated for 24 hours. The survival fraction (SF) value was detected by cell colony formation assay; the protein levels of the serine phosphorylation at 139 locus of histone (γ-H2AX protein), the key protein in homologous recombination repair pathway (Rad51 protein) and the cell autophage characteristic protein (LC3 protein) were detected by Western Blot; the formation of autophagosome was observed by transmission electron microscope.Results Aidi injection possessed the suppression of the growth of human lung adenocarcinoma A549 cells, the proliferation of the cells in various Aidi groups was lower than that in the blank control group, with the increase in drug concentration, the A549 cell growth inhibition ratio (IR) was gradually increased, representing a dose dependent manner, and the IC10 was 3.09 mg/mL. Compared with the blank control group, the SF value in Aidi control group was not significantly different [(94.7±3.85)% vs. (100.0±0.00)%,P > 0.05], the SF value in radiation group was decreased [(71.8±5.9)% vs. (100.0±0.0)%,P < 0.05], and in Aidi pretreatment group, the value was further decreased compared with that in radiation group [(51.9±4.7)% vs. (71.8±5.9)%,P < 0.05]. Compared with the blank control group, the expression of γ-H2AX protein in the three treatment groups was significantly increased, the degree of increase in Aidi pretreatment group was the most obvious, and it was significantly higher than that in radiation group (gray value: 1.44±0.11 vs. 0.93±0.09,P < 0.05). But the expression of Rad51 protein was the highest in radiation group, and it was higher than that in Aidi pretreatment group (gray value: 1.37±0.07 vs. 0.78±0.04, P < 0.05). Compared with the blank control group, the LC3Ⅱ/LC3Ⅰ value in Aidi control group, radiation group and Aidi pretreatment group were increased, and the degree of increase in Aidi pretreatment group was the most significant (0.35±0.06, 0.37±0.07, 0.49±0.06 vs. 0.05±0.04, allP < 0.05). Under transmission electron microscope, compared with the blank control group, the autophagosome in all treatment groups was increased to some extent, and the degree of increase in Aidi pretreatment group was the most remarkable.Conclusion Aidi injection has the enhancing effect of radiosensitization on human lung adenocarcinoma A549 cells, and its mechanism is possibly related to the up-regulation of A549 cell autophagy level.

Objective To verify a new revised method with low usage amount of arsenic trioxide for determining urinary iodine by As(Ⅲ)-Ce4+ catalytic spectrophotometry using ammonium persulfate digestion.Methods The standard curve linearity,sample detection limit,precision and accuracy of determining urinary iodine of this modified method were verified according to Determination Methods of Chemicals in Biological Materials.Results The linear correlative coefficients of the 0-300 μg/L range and 300-1200 μg/L range calibration curve were-0.9998--1.0000(n =6) and-0.9998--1.0000,respectively.The detection limit for iodine was 1.3 μg/L.The relative standard deviations were 1.5％ (1.1/71.3)-2.5％ (6.2/244.9) when measuring 3 urine samples with iodine concentration of 71.3-244.9 μg/L,and 0.6％(2.4/388.5)-1.7％(17.3/1018.0) when measuring 3 urine samples with iodine concentration of 388.5-1018.0 μg/L,respectively(n =6).The test results of the four urinary iodine national standard materials with iodine concentration of 73.0,206.0,556.0 and 883.0 μg,/L were all within the given value range and the average value relative deviation was 1.8％ (1.3/73.0),0.4％ (0.8/206.0),0.2％ (1.0/556.0) and-1.6％(-13.7/883.0),respectively (n =6).The average recovery was 98.8％ with a range of 93.2％ (186.3/200.0)-103.4％(51.7/50.0) when measuring 3 urine samples with iodine concentration of 64.6-144.9 μg/L and 3 urine samples with iodine concentration of 346.8-574.4 μg/L,respectively.Conclusions This new modified method greatly reduces the amount of waste containing arsenic,and can directly take urine samples with high iodine concentration to digest and determine without dilution.It is performed with good standard linear curve,better precision and high accuracy,and in line with the analysis of biological samples requirements.

The ability to induce hypersensity on leaves of tomato and the stability of double-plasmid of an harpin-producing, nitrogen-fixing engineered strain E4 were tested. Hypelsensitivity-inducing experiment indicated that the time and density of hypersensitivity-induction of E4 was similar to those of DH5, the positive control of pCPP430. Although E4 took the same time to induce hypersensitivity as 308R, another positive control of pCPP430, it induced weaker hypersen- sitivity on tobacco leaves. On tomato leaves, there was no difference in time and density of hypersensitivity between E4 and 308R (pCPP430). Results revealed that the two plasmids, pCPP430 and pMC73A, were unstable in host bacteria, with the losing rate of 100% at the 48th generation. The emergence probability of bacteria with either pCPP430 or pMC73A was almost the same.
