Objective To assess the effects of air pollution on health of traffic policemen. Methods Sampling and the analysis of air pollution were conducted according to China national standards. 214 traffic policemen were investigated. Of them 149 were working on the streets and 65 were working in the office (taken as the control). Individual respiratory symptoms occupational histories and medical records were obtained using standardized questionnaire. Results The prevalence rates of cough and expectoration excessive phlegm eyes and throat unwell fatigue in policemen working on the streets were significantly higher than that in policemen working in the office and were correlated to the level of air pollution(P

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

OBJECTIVETo explore the current application and features of Aconite prescriptions with incompatible herbs in grade A class three hospitals in east China and central China through a clinical study and comparative analysis.

METHODClinical prescriptions containing Aconite with incompatible herbs were collected. Association rules were utilized to analyze the compatible features of these herbs.

RESULTThis analysis found that the frequently used incompatible herba; pairs are Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, with the support rate of 44.45%, occupying nearly half of the surveyed prescriptions; Pinelliae Rhizoma is the most frequently used herb in the two areas, with support rate up to 76.24%. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata and Pinelliae Rhizoma, the top 10 herbs in Central China were mostly for warming the middle jiao and tonifying qi, such as Zingiberis Rhizoma, Atractylodis Macrocephalae Rhizoma and Codonopsis Radix; Whereas those in east China were mostly for activating and nourishing blood, such as Angelicae Sinensis Radix, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, the core herbal pairs applied in central China were mainly for resolving phlegm and warming the middle jiao, such as Pinelliae Rhizoma-Glycyrrhizae Radix et Rhizoma, Pinelliae Rhizoma-Zingiberis Rhizoma; Whereas those in east China were principally for activating blood and tonifying qi, like Atractylodis Macrocephalae Rhizoma and Pinelliae Rhizoma, Angelicae Sinensis Radix and Pinelliae Rhizoma. Among the core herbal groups in the two areas, the most frequently used herbal groups in the two areas are Aconiti Lateralis Radix Praeparata, Glycyrrhizae Radix et Rhizoma and Pinelliae Rhizoma with the support rate of 59.73%, accounting for the highest proportion among all of herbal groups.

CONCLUSIONThere are the combined clinical application of Aconite with incompatible herbs, mostly with Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, but with differences in the combined application in east China and central China.

Three osmotolerant yeasts were isolated from three batches of "swollen can" soy sauce produced by a Guangdong condiment plant. These strains grew faster in the media containing 50%～60% glucose or 15% NaCl than in common yeast media. The three yeasts were identified as Pichia etchellsii by using morphological characteristics, physiological and biochemical tests.

Permeabilized cells containing trehalose synthase from Meiothermus sp.CBS-01 was immobilized by the integration of entrapment in alginate beads with cross-linking and electrostatic self-assembly coating technique.Coating on alginate beads with diazo-resin and poly(styrene sulfonate) can protect the beads from degradation in phosphate buffer,whereas cross-linking with carbodiimide improves the thermostability of trehalose synthase entrapped in alginate beads.By co-immobilization of permeabilized cells using entrapment-cross-linking- coating method,the enzyme recovery was 32%,and the optimum temperature of the enzyme was still 60℃,but the optimum pH was shifted from 6.5 to 7.In batch manner,a maximum conversion yield of 60% trehalose from maltose could be reached by the immobilized cells.Within 4 times repeated use of the immobilized cells,and each time was operated at 50℃ for 24h,more than 50% conversion yield of trehalose could be maintained with less than 20% loss of the enzyme activity.

Objective To explore the best time point for the ipsilateral hepatocellular apoptosis and the contralateraI hepatic hypertrophy after selective portal vein embolization(SPVE)in rabbit.Methods In a randomized study design,forty rabbits were divided into 5 groups with 8 rabbits per-group,including one as the control and the other 4 were treated with SPVE during open surgery.The rabbits were killed postoperatively,in 3,7,14,21 days respectively after the embolization.The hepatic lobes volume,the ipsilateral hepatocellular necrosis rates and apoptosis index,and liver functions were determined as well. Results In the treatment groups,the average amount of the right liver volumes decreased from 46.4 cm~3 preoperatively to 46.0,44.4,42.0,39.7 cm~3 in groups of 3,7,14,21 days postoperatively;meanwhile,the left liver volumes increased from 54.0 cm~3 preoperatively to 54.5,56.3,61.7,63.9 cm~3 respectively during 3, 7,14,21 days after the procedures.The rates of future remaining live volumes(FRLV)increased from 53.8% preoperatively to 54.2%,55.9%,59.0%,61.0% at 3,7,14,21 days postoperatively.The apoptosis indexes of hepatocells from group A to E were 8.1%,12.2%,19.4%,20.1%,14.2% respectively.Conclusions SPVE leads to atrophy of the ipsilateral hepatic lobe and hypertrophy of contralateral lobe,indicating that hepatocytes undergone apoptosis,rather than necrosis.The time point is 7 to 14 days.
