Object To study the effects of SINI TANG (SNT) on the rat aortic rings pre-contracted by high K + and phenylephrine (Phe). Methods The effects of SNT on the aortic rings in the presence of 60 mmol/L KCl and Phe (1?10 -9 -1?10 -4 mmol/L) were observed and t heir me chanisms were studied after treatment with Propranolol (Pro, 3?10 -6 mmol/ L) and Bay K8644 (BK, 1?10 -5 mmol/L) as tool drugs. Results SNT inhibited the contraction induced by cumulative Phe and decreased the maximum tension (T max ); Pro couldn't influe nce the effects of SNT. SNT attenuated the amplitude of contractile effect of hi gh K +; BK couldn't reverse the effects of SNT. Conclusion SNT can shift the dose-response curve to the right and decrease the T max . It shows that SNT is a kind of noncompe titive antagonism. SNT decreases the effect of high K + against contraction of the artery. BK, a L-type Ca 2+ channels activator, couldn't recover the inhibition induced by SNT. The results suggest that SNT inhibit ? 1 recep tor, while calcium channel may not be involved in attenuating the effect of SNT on high K +-induced contraction.

5.Plasmid-mediated resistance to quinolones in Enterobacteriaceae
Journal of Medical Postgraduates 2004;0(01):-
Although quinolone resistance results mostly from chromosomal mutations in Enterobacteriaceae,it may also be mediated by plasmid-encoded Qnr determinants.Qnr proteins protect DNA from quinolone action and compromise the effect of quinolones,such as nalidixic acid.Qnr proteins including QnrA,QnrB and QnrS,have been identified worldwide with a quite high prevalence among Asian isolates with a frequent association with clavulanic acid-inhibited expanded-spectrum b-lactamases and plasmid-mediated cephalosporinases.The QnrA genes are embedded in complex sul1-type integrons.A close relative and likely progenitor of the QnrA have been found in the water-borne species Shewanella algae.It may help to determine the location of in vivo transfer of the QnrA genes.Further analyses of the role of quinolones,if any,in enhancing this gene transfer may prevent the spreading of the drug resistance and possibly lead to the finding of a novel mechanism of antibiotic resistance.
6.Progress on AmpC hyperproduction in Escherichia coli
Journal of Medical Postgraduates 2004;0(02):-
The ampC ?-lactamases gene in Escherichia coli(E.coli) is different from other Gram-negative bacteria.E.coli contains a chromosomal ampC gene which has a weak promoter as well as a transcriptional attenuator.The promoter of the ampC gene in E.coli is part of the preceding frd operon,the attenuator of the ampC gene is a transcription terminator for the frd operon.The ampC regulatory gene,ampR,is absent.Strains carrying the wild-type gene produce a low basal amount of AmpC.Studies on the molecular basis of AmpC overproduction in E.coli have shown that some hyperproducers contain mutation in the promoter region and/or attenautor and/or ampC-coding region of ampC,while others contain more than one copy of ampC.Acquisition of a stronger promoter or insertion of an insertion element containing promoter sequences or regulatory gene ampR has also been proposed as the molecular basis of hyperproduction of AmpC in some E.coli strains.Plasmid-mediated AmpC ?-lactamases have been discovered frequently in E.coli strains.This is another reason for hyperproduction of AmpC ?-lactamases.

Chinese Journal of Clinical Oncology 2014;(15):989-992
To study the general characteristics of cancer pain and to improve cancer pain diagnosis and treatment lev-el by prospective and open cross-sectional assessment of the clinical characteristics of patients with moderate to severe cancer pain. Methods:Patients with moderate to severe cancer pain were observed upon initial admission to the hospital from December 2012 to De-cember 2013. We assessed pain intensity, location, characteristics, and predisposing and mitigating factors and classified the pain by pathophysiology. Results:A total of 310 patients with moderate (101 cases, 32.58%) and severe (209 cases, 67.42%) pains were as-sessed. The top five cancers identified were lung cancer (102 cases, 32.90%), colorectal cancer (30 cases, 9.68%), pancreatic cancer (27 cases, 8.71%), breast cancer (24 cases, 7.74%), and gastric cancer (20 cases, 6.54%). These patients reported 533 cancer pain locations, including waist (132 cases), abdominal (125 cases), chest (88 cases), lower limb (71 cases), shoulder, neck, and upper limb (47 cases), pelvis (33 cases), perineal area (23 cases), and head and face (14 cases). The pain location of the pancreatic cancer was 90.63%consis-tent with the primary tumor site. The pathophysiology of the pain was classified as follows:bone pain (145 cases, 27.20%), visceral pain (138 cases, 25.89%), soft tissue pain (126 cases, 23.64%), and neuropathic pain (124 cases, 23.27%). The incidence of visceral pain in pancreatic cancer was 92.59%. Conclusion:A variety of common malignancies could cause moderate to severe pain, especially lung cancer. The clinical manifestation of pancreatic cancer pain is visceral pain. The location of this cancer was consistent with the pri-mary tumor site. No apparent specificity was observed in other cancer types.
