To carry out pathologic diagnoses and whole-genome sequence analyses of the Jaagsiekte sheep retrovirus (JSRV) in Xinjiang, China, we first observed sheep suspected to have the JSRV. Then, the extracted virus suspension was observed by transmission electron microscopy (TEM). Total RNAs from lungs of JSRV-infected sheep were extracted and reverse-transcribed using a cDNA synthesis kit. Six pairs of primers were designed according to the exogenous reference virus strain (AF105220). Reverse transcription-polymerase chain reaction was carried out from JSRV-infected tissue, and the whole genome of the JSRV sequenced. Our results showed: flow of nasal fluid ("wheelbarrow test"); different sizes of adenoma lesions in the lungs; papillary hyperplasia of alveolar epithelial cells; alveolar cavity filled with macrophages; dissolute nuclei in central lesions. TEM revealed JSRV particles with a diameter of 88 nm to 125. 4 nm. The full-length of the viral genome sequence was 7456 bp. BLAST analyses showed nucleotide homology of 96% and 95% compared with that of the representative strain from the USA (AF105220) and UK (AF357971). Nucleotide homology was 89.8% and 89.9% compared with the endogenous Jaagsiekte sheep retrovirus, Inner Mongolia strain (DQ838493) and USA strain (EF680300). The specific pathogenic amino-acid sequence "YXXM" was found in the TM district, similar to the exogenous JSRV: this gene has been reported to be oncogenic. This is the first report of the complete genomic sequence of the exogenous JSRV from Xinjiang, and could lay the foundation for study of the biological characteristics and pathogenic mechanisms of the pulmonary adenomatosis virus in sheep.

This study was aimed to compare the pharmacokinetics (PK) of Shengmai injection and Shenmai injection with a single injection administration using a constant speed in subjects with stable angina pectoris.A total of 20 subjects with stable angina pectoris were divided into two groups.Each group was administered with Shengmai and Shenmai injection.The liquid chromatography-mass spectrometry (LC/MS) was adopted to determine concentrations of ginsenosides in plasma at different time points.PK parameters were calculated for comparison.The results showed that after a single intravenous infusion of Shengmai and Shenmai injection,the Cm.of ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1 and ginsenoside Rc in Shenmai group were higher than those of the Shengmai group with statistical significance (P ≤0.05).There were differences on the T1/2 of ginsenoside Rg1,AUC0-144h and CL of ginsenoside Rc,as well as Tmax of ginsenoside Rd (P ≤ 0.05).However,there was no significant difference shown on other PK parameters.It was concluded that after a single Shengmai or Shenmai injection,there were PK differences of ginsenoside Rg1,ginsenoside Re,ginsenoside Rb1 and ginsenoside Rc in the human body.The clinical medication selection should be based on syndrome differentiation and treatment of patients.

This study was aimed to establish the pharmacokinetics-pharmacodynamics (PK-PD) model of ginsenoside Rb1 following the intravenous administration of Shengmai injection in subjects with stable angina pectoris.A total of stable angina pectoris were selected and received Shengmai injection for 14 days.Plasma samples were collected at different time points.Plasma concentrations of ginsenoside Rb1 were determined by liquid chromatography-mass spectrometry (LC/MS).The concentration-time curves (AUC) were drawn,and then the PK parameters were calculated.The systolic pressure and diastolic pressure were monitored,and the combined PK-PD model was established based on the theory of effect compartment.The results showed that PK of ginsenoside Rb1 conformed to a mono-compartment model.The effect of Shengmai injection lagged behind the concentrations of ginsenoside Rb1 in plasma.The effect exhibited good correlation with ginsenoside Rb1 in effect compartment.The relationship between effect and plasma concentrations fits the Inhibitory Effect Imax model.It was concluded that the study successfully established the combined PK-PD model of ginsenoside Rb1 in subjects with angina pectoris.The model can efficiently evaluate the effective substance of Shengmai injection.

Objective To investigate the development trend of drinking-water-borne endemic fluorosis in Jiangsu Province,and to provide the basis for further prevention and treatment of the disease.Methods In 2009,eight major counties were chosen,and in each county all diseased villages were classified into light,moderate and severe disease types according to water fluorine content based on historical data,and one village was chosen from each type.In monitoring villages with improved water,one source water and three tap water samples were collected,respectively.Five water samples were collected in water unimproved monitoring villages according to water well locations of the east,the west,the south,the north and the center.The fluorine content in water was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006).Children aged 8 to 12 were examined for dental fluorosis by Dean method.Residents over the age of 16 were examined for clinical osteofluorosis,and two monitoring counties were chosen,then one village was respectively chosen in each county,and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray.Both clinical and X-ray diagnosis were on the basis of Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008).Urine samples of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method(WS/T 89-1996).Results Of all the 24 villages of 8 counties,20 villages were water improved,and water-improvedprojects ran normally in 18 villages,while scrapped in the rest 2 villages.One hundred and two samples were tested,and the mean of water fluoride in water-improved villages was 1.10 mg/L,while in water unimproved villages and villages with water improved projects scrapped was 1.90 mg/L.The prevalence of dental fluorosis was 42.51％(854/2009).The prevalence of clinical skeletal fluorosis was 23.23％ (2024/8713) and the X-ray detection rate was 32.00％ (24/75).Six hundred and sixty-four urine samples of children were determined,and geometric mean of urinary fluorine was 1.59 mg/L,while 370 adult urine samples were determined,and geometric mean of urinary fluorine was 2.20 mg/L.Conclusions Endemic fluorosis in Jiangsu Province has not been fully controlled and there are signs of recovery.We must pay attention to water improvement measures to reduce fluoride and the management and maintenance of water improvement projects,and further strengthen the prevention and control of endemic fluorosis.

OBJECTIVE:To study the pharmacokinetics of the active ingredients of Shenmai injection,including ginsenoside Rg1 and ginsenoside Re,in normal Beagle dogs and those with myocardial ischemia. METHODS:6 Beagle dogs were given isopro-terenol hydrochloride (1.1 mg/kg) sc to establish the model of myocardial ischemia (model group). Another 6 Beagle dogs were given isometric normal saline (2.2 ml/kg) sc as controls group. The two groups of dogs respectively received corresponding drugs sc at 8:00 am and 13:00 pm on day 1 and at 8:00 am on day 2. Each group of dogs were given Shenmai injection(1.6 ml/kg)iv 1 h after administration on day 2,and such intravenous drip lasted for about 1 h. Blood was collected from each group 0,0.25, 0.5,0.75,1(the end of iv),1.5,2,3,4,6,8,12 and 24 h from the start of iv. Liquid chromatography-mass spectrometry was adopted to determine the concentrations of ginsenoside Rg1 and ginsenoside Re in blood,and WinNonlin 6.3 was used to calculate pharmacokinetic parameters for comparison. RESULTS:For ginsenoside Re in the dogs of the model group,t1/2 was(2.69±1.12) h,AUC0-24 h was(2 060.78±812.18)h·μg/L,Vz was(46.16±20.98)ml and CL was(9.02±4.45)ml/h;compared to the normal control group,AUC0-24 h was much greater and Vz and CL were significantly lower,showing a statistically significant difference(P<0.05). No significant difference in the pharmacokinetic parameters of ginsenoside Rg1 was shown between 2 groups(P>0.05). CON-CLUSIONS:Myocardial ischemia may affect the removal of ginsenoside Re in Beagle dogs,but has no effect on the pharmacoki-netic process of ginsenoside Rg1.

OBJECTIVETo observe the intervention of Shenkangling Decoction (SD) on the renal injury of primary nephrotic syndrome (PNS) children patients of Shen deficiency blood stasis syndrome (SDBSS) and to explore its mechanism.

METHODSTotally 65 PNS children patients were randomly assigned to the combined group (33 cases, treated by SD +Western medicine) and the Western medicine group (32 cases, treated by Western medicine). Meanwhile, 30 healthy children were recruited as the healthy control group from the medical examination center. Those in the Western medicine group were treated with prednisone (5 mg per tablet) at the daily dose of 1.5 -2.0 mg/kg till two weeks after their urine protein turned to negative. Then the dosage was reduced once daily per every other day. The therapeutic course lasted for more than 1 year. For those with no effect of prednisone or partial effect, cyclophosphamide intravenous pulse therapy was additionally applied for 2 successive days per week, a total of 6 times, or they took cyclosporine A. Patients in the combined group additionally took SD while starting treatment of prednisone. SD was decocted in water for oral dose, once daily, taken in two portions until 2 months after prednisone was discontinued. Efficacy was evaluated based on serum levels of chemotactic factor CXCL16, disintegrin metalloproteinase 10 ( ADAM10 ), disintegrin metalloproteinase 17 (ADAM17), albumin (ALB), total cholesterol (TC), and 24-h urine protein excretion (UPE) detected by ELISA before and after treatment.

RESULTSCompared with before treatment in the same group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE were significantly lower in the two treatment groups (P <0. 01). Compared with the control group, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly increased, and the serum ALB level decreased in the two treatment groups (P <0.01). Compared with the Western medicine group at the same time point, levels of CXCL16, ADAM10, ADAM17, TC, and 24-h UPE significantly decreased in the combined group. The 1 -year recurrence rate and the recurrence times decreased in the combined group (P <0.01). The complete remission rate increased in the combined group (P <0.01).

CONCLUSIONSD could effectively improve the clinical prognosis of PNS children patients possibly by reducing the release of inflammatory mediators such as CXCL16, ADAM10, and ADAM17, decreasing UPE and the TC level, and elevating the serum ALB level.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.
