International Journal of Surgery 2009;36(9):620-623
The morbidity of pancreatic duct calculus is increasing every year in China. Currently the main therapeutic methods include non-surgical treatment and surgical treatment. 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.
2.Research progress on treatment of myelodysplastic syndromes with demethylating drugs
Chinese Journal of Clinical Oncology 2015;(18):895-899
Abnormal epigenetics play important roles in the pathogenesis of myelodysplastic syndromes (MDS). DNA hypermeth-ylation is the most common epigenetic abnormality in MDS. Demethylating DNA hypermethylation may improve the quality of life of MDS patients and prolong their overall survival. Azacitidine and decitabine are the demethylating drugs approved for MDS treatment. These drugs showed clinical effects on all subgroups of MDS patients.
3.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.

5.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.

Chinese Journal of Clinical Oncology 2013;(24):1492-1494
Neurolytic celiac plexus block (NCPB) is an effective method used to alleviate upper abdominal pain or back pain caused by pancreatic cancer and other malignancies. NCPB can relieve cancer pain to improve the quality of life and cause fewer side effects than conventional analgesic drugs. This article systemically reviewed NCPB methodology and research progress in clinical appli-cations.
7.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.

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.
10.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.
