The continuous cultivation of Rehmannia glutinosa causes the accumulation of phenolic acids in soil. It is supposed to be the reason of the so called "continuously cropping obstacle". In this study, phenolic acids (hydroxybenzoic acid, vanillic acid, eugenol, vanillin and ferulic acid) were degraded by the extracta of all the tested spent mushroom substrate (SMS) and the maximal degradation rate was 75.3%, contributed by extraction of SMS of Pleurotus eryngii. Pot experiment indicated that hydroxybenzoic acid and vanillin in soil were also degraded effectively by SMS of P. eryngii. The employment of SMS enhanced ecophysiology index to near the normal levels, such as crown width, leaves number, leaf length, leaf width and height. At the same time, the fresh and dry weight and total catalpol concentration of tuberous root weight of R. glutinosa was increased to 2.70, 3.66, 2.25 times by employment of SMS, respectively. The increase of bacteria, fungi and actinomycetes numbers in rhizosphere soil were observed after the employment of SMS by microbial counts. The employment of SMS also enhanced the enzyme activity in soils, such as sucrase, cellulase, phosphalase, urease and catelase. These results indicated that the employment of SMS alleviated the continuously cropping obstacle of R. glutinosa in some extent.

To establish a high performance liquid chromatography (HPLC) coupled with tandem mass spectrometry quantitative detection method for the determination of curcumol, the main ingredient of zedoary turmeric oil fat emulsion, and investigate its pharmacokinetics in Beagle dogs, nine healthy Beagle dogs were divided into three groups, and blood samples were collected at scheduled time points after intravenous injection of 7.5, 10 and 12.5 mg x kg(-1) zedoary turmeric oil fat emulsion. The concentrations of curcumol were determined and pharmacokinetics was calculated. A good linearity was obtained from 0.25 to 100 ng x mL(-1) in plasma. The relative recoveries were from 91.33% to 103.17%, and the absolute recoveries were from 31.61% to 37.20%. The intra-day and inter-day variances (RSD) were < 15%. The main pharmacokinetic parameters of curcumol after intravenous injection of 7.5, 10 and 12.5 mg x kg(-1) zedoary turmeric oil fat emulsion were as follows, T1/2 : (2.0 +/- 0.4), (1.7 +/- 0.2) and (2.3 +/- 0.8) h, AUC(0-infinity): (15.1 +/- 2.7), (18.3 +/- 2.0) and (29.5 +/- 4.0) ng x mL(-1) x h; MRT: (0.9 +/- 0.1), (0.8 +/- 0.2) and (0.8 +/- 0.1) h, CL: (21.9 +/- 4.0), (24.9 +/- 6.0) and (18.4 +/- 1.2) L x h(-1) x kg; Vd : (65.4 +/- 26.5), (62.0 +/- 13.4) and (61.2 +/- 19.8) L x kg(-1), respectively. The developed method was rapid, highly sensitive and specific and could be used in curcumol pharmacokinetic studies in vivo. A three-compartment model was best fit to the plasma concentration--time curves obtained in Beagle dogs and the plasma AUC was increased proportionally with doses.

OBJECTIVETo explore the correction for shortened and broaden prolabium deformity following bilateral cleft lip repair.

METHODSWe designed the upper lip double flag-shaped flaps. The quadrilateral original surgical scar (flap flag pole part) was resected and the incision was made along the direction of nasolabial groove at the nostrils bottom to form two flag-shaped flaps (the section of the flag face). Lip tubercle were tracted and blunt dissection of upper philtrum were performed to form a wound, 4-6 mm in width. The flag-shaped flaps on both sides were rotated to the central, in order to form a new nasal base and new prolabium, followed by V-Y or Z plasty procedure to correct the defect of tubercle and vermilion.

RESULTS10 cases were enrolled for the clinical application from January 2008 to December 2012. The height of the prolabium was lengthened by 4-6 mm after operation, which fundamentally corrected shortened and broaden prolabium deformity after bilateral cleft lip operation. The procedure can also correct the depression or defect of tubercle, too wide philtrum, philtrum column scar and the deformity of vermilion border continuity. The patients were followed up for a period of 3 months to 3 years with satisfactory results.

CONCLUSIONDouble flag-shaped flaps of the upper lip at the nostrils bottom is a simple and good surgery method to correct the shortened and broaden prolabium deformity following bilateral cleft lip repair.

A single dose of 3H-norcantharidin solution was intragastrically given, blood, tissues, urine and feces were collected as scheduled, and radioactivity in these samples was determined by tritium tracing method to investigate the pharmacokinetics, tissue distribution and excretion of norcantharidin in Kunming mice. The pharmacokinetic characteristics of norcantharidin were evaluated by DAS version 2.0. The blood concentration reached to maximum 0. 5 h after intragastric administration. The radioactivity in tissues was high in small intestine, gallbladder, stomach, adrenal gland, kidney, heart and uterus 15 minutes after administration, descending with time, and high in gallbladder, adrenal gland and uterus 3 hours post dosing. The 24 h accumulative excretion ratio of urine and feces were 65.40% and 1.33% respectively. 3H-norcantharidin was easily absorbed after orally given to mice, the radioactivity was high and existed for a long-time in gallbladder, adrenal gland and uterus, and low but also existed for a long-time in large intestine, thymus and fat tissue. 3H-norcantharidin was declined quickly in small intestine, stomach, kidney and heart, and occurred rarely in brain. Norcantharidin was excreted mainly by urinary route and seldom in feces, which may be the cause of the urinary stimulation side effects observed. Because the radioactivity measured were the sum of 3H labeled norcantharidin and its metabolites, further studies on the disposition of norcantharidin in mammal animals, on the separation or identification of metabolites and, if any, on their activities, are fairly needed.

Sustained activation of β adrenergic receptor (βAR) leads to pathologic cardiac hypertrophy. However, the related mechanisms still remain unclear. In this study, we observe how N-acetylcysteine (NAC) affects the oxidative stress and calcium/calmodulin-dependent protein kinase II (CaMKII) expression in heart of isoproterenol (ISO)-stimulated rats, and investigate whether oxidative stress and CaMKII contribute to the development of sustained βAR-stimulated cardiac hypertrophy. Healthy male Wistar rats were randomly separated into 4 groups: control (CTRL), ISO-treated (ISO), control with NAC supplement (CTRL+NAC) and ISO-treated with NAC supplement (ISO+NAC) groups (6 rats in each group). Systolic blood pressure (SBP) was measured in awake rats with the tail-cuff method every week for two weeks. Heart weight/body weight ratio (HW/BW) and HE staining were used for the detection of myocardial hypertrophy. Myocardial mitochondrial reactive oxygen species (ROS) levels were measured by DCF fluorometry. The expressions of activated-CaMKII (p-CaMKII/CaMKII) and NADPH oxidase 4 (NOX(4)) were determined by Western blot analysis. The results showed that ISO-treated (i.p., daily 3 mg/kg, 2 weeks) rats developed an obvious cardiac hypertrophy as expressed by increases of HW/BW and myocyte cross-section area. Cardiac mitochondrial ROS level was significantly enhanced in ISO group as compared to CTRL group (P < 0.05). The expressions of NOX(4) and p-CaMKII in ISO group were also up-regulated as compared to CTRL group (1.4 and 1.6 times of CTRL, respectively, P < 0.05). NAC supplement significantly suppressed the hypertrophic development of heart in ISO-stimulated rats. The cardiac mitochondrial ROS level showed a significant decrease in rats of ISO+NAC group (P < 0.05 vs ISO). In accordance with this, ISO+NAC group rats also showed marked reductions in the expressions of NOX(4) and p-CaMKII/CaMKII compared to ISO group rats (P < 0.05). There were no significant differences of the detected indices between the rats from CTRL+NAC and CTRL groups. SBP showed no differences among four groups. These results suggest that both oxidative stress and CaMKII play important roles in sustained βAR-stimulated cardiac hypertrophy. NAC may suppress ISO-induced cardiac hypertrophy by down-regulating the expression of activated-CaMKII, and by reducing the level of oxidative stress originated from mitochondria and NADPH oxidase pathways.

OBJECTIVETo explore the acting mechanism of viscera purging method (VP) in purging Fu-organs and benefiting Fei from integral, cellular and molecular levels.

METHODSForty SD rats were equally divided into four groups randomly: the normal group, the model group, the unhitch group and the VP group. Except those in the normal group were untreated, rats were established to intestinal obstruction model by incomplete ligation of the rectum in vitro. The ligation was relieved 48 h after operation in the unhitch group and the VP group, and the animals were fed continuously on routine. Meanwhile, Dachengqi Decoction (DD) 2 ml was given twice a day to the VP group for 2 days. Finally, the serum interleukin 8 (IL-8) and mRNA expression of tumor necrosis factor-alpha (TNF-alpha) in the lung tissue were detected by radioimmunoassay and RT-PCR respectively. Besides, the number of pulmonary alveolar macrophages (PAM) in the bronchial alveolus lavage fluid (BALF) was counted and their death rate calculated.

RESULTSCompared with the normal control, the serum IL-8 content in lung tissue in the model rats were remarkably higher (P < 0.01); however, the VP group showed the lowest level of IL-8 content and the highest was shown in the model group. Number of PAM in BALF was higher and its death rate was lower in the VP group than that in the unhitch groups (both P< 0.05). The expression of TNF-alpha mRNA was sinificantly higher as compared with that in the normal group, and lowered after administration of DD.

CONCLUSIONViscera purging method could protect the injured lung tissue to some extent.
