ObjectiveTo investigate the efficacy of acupoint application with direct current in treating ankylosing spondylitis. MethodA clinical controlled trial was carried out. Sixty patients were randomly allocated to two groups. The treatment group was given acupoint application with direct current plus sulfasalazine and the control group, sulfasalazine alone. The course of treatment was two months. Inflammation indices, and the SF-36 health survey, BASDI, BASFI, night pain VAS and spinal pain VAS scores, and liver and kidney functions were observed in the patients before and after treatment.ResultInflammation indices, and the SF-36 health survey, BASDI, BASFI, night pain VAS and spinal pain VAS scores took a turn for the better in both groups after treatment. The therapeutic effect was better and the TCM symptom score was lowerin the treatment group than in the control group (P<0.05). ConclusionAcupoint application with direct current for treating winter diseases in summer has a therapeutic effect on ankylosing spondylitis.

Objective: To investigate the developmental toxicity of 2,4-dinitrochlorobenzene in zebrafish embryos. Methods: AB wild-type male and female zebrafish were selected to mate and spawn, then the eggs were cultured with Holt buffer solution. Six dose groups ( 0.4, 0.8, 1.0, 1.2, 1.6, 2.0 μg/mL ), a solvent control group and a cosolvent control group, were set up with 20 embryos each. Malformations and death of embryos were observed at 48, 72 and 96 hpf ( hours post fertilization ), the mortality and 50% lethal concentration ( LC50 ) were also calculated. Results: At 48, 72 and 96 hpf, the LC50 of 2,4-dinitrochlorobenzene on zebrafish embryos were 1.668, 1.043 and 0.895 μg/mL, respectively, with a downward trend. After 72 hpf, when the concentration reached 2.0 μg/mL, all the zebrafish died. In the range of 0.4-2.0 μg/mL, the mortality of zebrafish at 48, 72 and 96 hpf increased with the increase of 2,4-dinitrochlorobenzene concentration ( all P<0.05 ); the malformation rate of zebrafish embryos at 48 hpf increased with the increase of 2,4-dinitrochlorobenzene concentration ( P<0.05 ). Zebrafish embryos exposed to 2,4-dinitrochlorobenzene led to yolk sac edema, pericardial edema and spinal curvature. Conclusion 2,4-dinitrochlorobenzene can affect the development of zebrafish embryos, which will lead to lethal and teratogenic effects.

Objective To assess the risk factors of postphlebitic syndrome(PS)after deep vein thrombosis of the lower extremities.

To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.

From 2006 to 2008, the susceptibility of different species of animal hosts to Campyebacter jejubni infection was observed in various areas of Jiangsu province, in which the API Campy System was used to perform the biochemical identification and the multiple PCR assay was employed to analyse the C.jejuni isolates from 3010 specimens of fouls. Cattle, pigs and monkeys, and in addition, the susceptibility of isolates to various antibiotics was also determined. In these specimens investigated 402 samples were found to be positive in the detection of C.jejuni with a positive detection rate of 13.36%. The positive detection rates in chicken, water fouls, milk cows, pigs, monkey, red crowned crane and wapiti were 15.83% (258/1630), 10.4% (52/100), 8.24% (42/510), 15.63% (25/160), 15% (15/100), 12.5% (15/80) and 0% (0/30) respectively. Meanwhile, the antibiotics to which the isolates from different hosts showed high rate of sensitivity to 27 antibiotics of 10 varieties included: chloromycetin (100%), Almocylin (99.7%), amicarcin (92.59%), cefprozil (91.67%), alchimycin (90.74%); while the antibiotics to which these isolates showed high rate of resistance were compound neoromin (99.7%), cefoperazone (99.07%), trimethoprim (97.22%), cepronatin (91.67%), cepromondo (99,07%) respectively. It is evident that the susceptibility of different hosts to C.jejuni infection and the status of drug-resistance of the isolates appear to be quite different and more complicated in Jiangsu province.
