2.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.

Non-surgical treatments contain endoscopic calculus extracting and / or extracorporeal shock wave lithotripsy. Surgical treatment has two categories: drainage of the pancreatic duct decompression and pancreatectomy. Concrete treatment or surgical options should follow the strategy of individual.
5.Analysis of clinical characteristics of 310 patients with moderate to severe cancer pain
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.
6.Progress on application of adjuvant analgesics in cancer pain man-agement
Chinese Journal of Clinical Oncology 2015;(10):530-534
Adjuvant analgesics refer to a group of drugs that are used not only to treat certain diseases but also to induce analge-sia. Such drugs demonstrate different mechanisms based on the complexity of cancer pain. Thus, opioids, nonsteroidal drugs, and adju-vant analgesics are often combined to control cancer pain. According to the WHO three-step analgesic ladder, adjuvant analgesics can be used at any cancer stage, and the usage of these drugs combined with opioids can reduce the required dosages of these pain relievers, thereby alleviating the adverse reactions associated with opioid use. Moreover, these drugs are particularly suitable for neuropathic pain patients who are not fully sensitive to opioids. The commonly used adjuvant analgesics include antidepressants, anticonvulsants, local administration drugs, corticosteroids, and N-methyl-D-aspartate (NMDA) receptor antagonists. Various adjuvant analgesics also differ in usage and dosage based on primary disease treatment. Therefore, clinical doctors should determine the adverse reactions, proper dos-age, and subsequent amount of dosage to be added in a few days or weeks to achieve balance between the desired effect and adverse re-actions.

The acupuncture group received western medicine combined with acupuncture and the control group received simple Western medicine. Results:The effective rate was 92.0% in the acupuncture group and 62.5% in the control group. There was a very significant difference in curative effect between the two groups(P< 0.01). Conclusion: The curative effect of combined acupuncture and medicine on pseudobulbar paralysis is significantly better than that of simple Western medicine.
9.Advances of the studies on lymphoid neoplasma associated anemia
Journal of Leukemia & Lymphoma 2010;19(4):249-253
Anemia is one of the most common complication and a negative prognostic factor of lymphoid neoplasma.Different cases with lymphoid neoplasma associated anemia(LNAA)have various pathogenesis such as hemorrhagic anemia, anemia of chronic disease,autoimmune hemolytic anemia and treatment related anemia, though they all have the same symptoms. So different regimens are given to different patients according to their pathogenesis of LNAA.
10.Adenosine promotes bFGF protein and bFGF mRNA expression in human umbilical vein endothelial cells in vitro
Chinese Journal of Pathophysiology 1989;0(05):-
AIM: To investigate the influence of adenosine on human umbilical vein endothelial cells (HUVEC) bFGF protein production and bFGF mRNA expression. METHODS: Immunohistochemistry staining was performed to detect bFGF protein. RT-PCR was performed to detect bFGF mRNA expression. RESULTS: Immunohistochemistry study demonstrated that there was only a small amount of bFGF positive cells and the color was weak in control group (without adenosine). In groups treated with 10~-4 mol/L and 10~-6 mol/L adenosine, bFGF protein was significantly higher than that in control group (P0.05). RT-PCR showed that in 10~-4 mol/L and 10~-6 mol/L adenosine groups, bFGF mRNA expression was higher than that in control group (P0.05). CONCLUSION: Adenosine may promote HUVEC proliferation and angiogenesis partly through inducing bFGF expression.
