Objective:To discover the epidemic characteristics of brucellosis in Yunnan Province, and establish a grey GM (1, 1) model to predict brucellosis in Yunnan Province.Methods:The epidemic data of incidence rate of brucellosis and population data in Yunnan Province from 2008 to 2018 were collected from China Disease Prevention and Control Information System and Yunnan Provincial Bureau of Statistics. Epidemiological characteristics (including time, area and population distributions) were analyzed, and grey GM (1, 1) model was used to predict the incidence of brucellosis in Yunnan Province in 2019 and 2020.Results:A total of 1 216 brucellosis cases were reported in Yunnan Province from 2008 to 2018, with an average annual incidence rate of 0.237 4/100 000, showing an increasing trend year by year (χ 2trend = 843.34, P<0.01). Case reports were mainly from March to September, accounted for 69.41% (844/1 216) of the total number of cases. The top five regions with case reports were Honghe (289 cases), Qujing (264 cases), Kunming (258 cases), Dali (160 cases), and Yuxi (134 cases), accounting for 90.87% (1 105/1 216). The occupation was mainly farmers, accounting for 79.03% (961/1 216). A grey GM (1, 1) model was established to predict the incidence of brucellosis in Yunnan Province in 2019 and 2020, which was 0.487 6/100 000 and 0.481 7/100 000, respectively. Conclusion:The incidence of brucellosis in Yunnan Province has increased compared with that of the past, and targeted prevention and control should be carried out in key areas and key populations, and the prediction results should be prospectively evaluated to gradually improve the establishment of brucellosis prediction model in Yunnan Province.

Objective To study the biological characteristics of arsenic resistance cell model chronic arsenic exposure human bone marrow mesenchymal stem cells (CAsE-hFBMSCs) and discuss the consequence of chronic arsenite exposure to human mesenchymal stem cells (hFBMSCs). Methods hFBMSCs cultivated under general conditions,hFBMSC cell survival rate was detected in 48 hours with arsenite toxicity test under different doses arsenic [0(control),0.25,0.50,1.00,2.00,4.00,8.00,20.00,40.00,80.00,120.00 μmol/L]of the fist 2-generation(P2). According to the test results,1.00 μmol/L sodium arsenite was chosen to stimulate hFBMSCs for 14 weeks as experimental group,simultaneous 0 μmol/L sodium arsenite as the control group. And then,the phenotype was detected by fluorescence-activated cell sorting,and the cell cycle by flow cytometry. Finally,the cell malignant transformation was detected by soft-agar assay. Results Arsenite low than 10 μmol/L promoted cell proliferation,but inhibited cell proliferation when exceeding 10 μmol/L. Half of the lethal dose (LC_(50)) in experimental and control groups were (89.42±0.64),(52.48±0.71)μmol/L. The difference between two groups was statistically significant(t = 123.89,P < 0.05). The phenotype of CAsE-hFBMSCs was CD29,CD90,CD166 positive and CD34,CD45 negative. The phenotype of CAsE-hFBMSCs was the same as the control. Comparing to control group[(8.44±0.45)%,(9.14μ0.14)%,(82.42±0.60)%],G2/M phage[(17.72±5.47)%]and S phage [(25.34±3.36)%]cell increased,G0/G1 phage[(56.96±8.83)%]cell decreased in P2 CAsE-hFBMSCs. The cell cycle became nearly the same as the control group after adaption. CAsE-hFBMSCs did not show clone formation in soft agar clone formation assay. Conclusion Long last and low level exposure to arsenite does not influence the biologic features of hFBMSCs.

OBJECTIVE: To investigate the inhibition effects of Tianshen Yizhi Recipe (TSYZR), a compound traditional Chinese herbal medicine, on decreased expression of nicotinic acetylcholine receptor (nAChR) and the neurotoxicity as well as lipid peroxidation induced by beta-amyloid peptide (Abeta) in human SH-SY5Y neuroblastoma cells. METHODS: The SH-SY5Y cells were treated by a certain concentration of TSYZR, and then exposed to Abeta(25-35). Methyl thiazolyl tetrazolium reduction assay was carried out to understand the influences of the drugs on cellular viability. Expressions of nAChR subunits (alpha3 and alpha7) at protein and mRNA levels were detected by Western-blotting and reverse transcription polymerase chain reaction, respectively. Lipid peroxidation was measured by thiobarbituric acid to observe the capacity of antioxidant of the drugs. RESULTS: TSYZR at a safe concentration could increase alpha7 protein in the cells, inhibit decreased expressions of alpha3 and alpha7 nAChR subunit proteins, prevent lower expression of alpha7 mRNA in SH-SY5Y cells induced by Abeta, reduce the neurotoxicity and lipid peroxidation resulting from Abeta, but had no significant effect on the lower expression of alpha3 mRNA. CONCLUSIONS: TSYZR can up-regulate the expression of alpha7 nAChR subunit protein and prevent decreased expressions of nAChRs and neurotoxicity as well as lipid peroxidation induced by Abeta. This drug may play an important therapeutic role in treatment of Alzheimer disease.

A sensitive LC-MS/MS method to determine cocaine and its major metabolite benzoylecgonine in guinea pig' s hair has been established. About 20 mg of decontaminated hair sample was hydrolyzed with 0. 1 mol x L(-1) HCl at 50 degrees C overnight, in the presence of cocaine-d3 and benzoylecgonine-d8 used as internal standards, and then extracted with dichlormethane. The analysis was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Positive electrospray ionization (ESI +) and multiple reactions monitoring (MRM) mode were used. The limit of detection (LOD) for cocaine and benzoylecgonine was 1 pg x mg(-1). The calibration curves of extracted standards were linear over the range from 5 pg x mg(-1) to 250 pg x mg(-1) (r2 > or = 0.9997). The method was validated and applied to the analysis of guinea pig's hair after a single dose administration of cocaine hydrochloride. Cocaine and benzoylecgonine were not only detected, but also quantified in guinea pigs hair.

OBJECTIVE:
To establish a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous analysis of cocaine (COC) and its metabolite benzoylecgonine(BZE) in urine samples.
METHODS:
A single dose of COC (10 mg/kg) was injected intraperitoneally into guinea pigs and urine samples were collected for 7 days. The urine samples were extracted by auto solid phase extraction (SPE), separated by the Allure PFP propyl column with a mobile phase consisting of methanol and 20 mmol/L ammonium acetate buffer [0.1% formic acid (80:20, V/V)], and then analyzed by LC-MS/MS. Multiple reaction monitoring (MRM) mode was used to analyze COC (m/z 304.2-->182.3, m/z 304.2-->150.1) and BZE (m/z 290.2-->168.3, m/z 290.2-->105.0).
RESULTS:
COC and BZE showed a fairly good linearity over the range of 2.0-100 ng/mL (r=0.9995). The detection limit was 0.5 ng/mL. The recovery rate was greater than 90% and the deviation of intra- and inter-day precision was less than 6%. BZE was the major target detected in urine samples, and its detection window was longer than COC.
CONCLUSION
This newly developed method shows high sensitivity and selectivity, and is suitable for the simultaneous analysis of cocaine and benzoylecgonine in urine samples.

To investigate theological properties of common hydrophilic gel excipients such as Carbopol based on viscosity, the viscosity was determined by rotation method and falling-ball method. Linear regression was made between ln(eta) and concentration, the slope of which was used to explore the relation between viscosity and concentration of different excipients. The viscosity flow active energy (E(eta)) was calculated according to Arrhenius equation and was used to investigate the relation between viscosity and temperature of different excipients. The results showed that viscosities measured by two methods were consistent. Concentration of guargum (GG) and hydroxypropylmethyl cellulose (HPMC) solution had a great influence on the viscosity, k > 5; while concentration of polyvinylpyrrolidone-K30 (PVP-K30) and polyethylene glycol 6000 (PEG6000) exerted a less effect on viscosity, k < 0.2; viscosity flow active energy of different excipients were close, which ranged from 30 to 40 kJ x mol(-1). Therefore, theological properties study could provide the basis for application of excipients and establish a foundation for the research of relation between excipients structure, property and function.

OBJECTIVETo investigate the effects of icariin on the streptozocin (STZ)-induced epididymis impair in rats.
METHODSThe epididymis impair was induced by injection of streptozocin at dosage of 60 mg/kg ip in SD rats. Animals were randomly divided into six groups (n = 14): normal control, model group, three icariin treated group with different dosages (P.O, 20 mg/kg, 40 mg/kg, 80 mg/kg especially) and rosiglitazone group (P.O, 3 mg/kg), 12 weeks later, animals were sacrificed. The level of serum glucose, the activity of lactate dehydrogenase (LDH), acid phosphatase (ACP), gamma-glutamyltranspeptidase (gamma-GT), alpha-glucosidase activity as well as sialic acid (SA), fructose level in the epididymis were determined. The pathological examination was performed under microscope after the epididymis was fixed by 4% poly-formalin and stained by HE.
RESULTSCompared with the normal control, the activity of LDH, ACP, gamma-GT and alpha-glucosidase in the epididymis revealed a decline, with lower level of SA and fructose. Histological examination showed that mature spermatocytes in the epididymis markedly decreased. These alterations were ameliorated in the groups with the treatment of icariin at 40 mg/kg and 80 mg/kg, but not at 20 mg/kg.
CONCLUSIONIcariin ameliorated the signs of epididymis in diabetic rats induced by streptozocin, this effect might carry out by promoting the elevation of special enzyme and energy metabolism in the epididymis.
