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.

Objective To study the effect of microecologic modulator combined with antibiotic in treatment of infantile diarrhea.Methods 150 children with diarrhea in our hospital were selected as the research subjects,they were randomly divided into observation group and control group,75 cases in each group.The observation group used tyrosine aureus triple viable bacterial combined with amoxicillin therapy,the control group received lactasinum biofermin, vitamin for oral treatment.The curative effect,clinical symptoms and inflammatory factors TNF -ɑ,IL -6,IL -10 changes after treatment for 2 months were compared in the two groups.Results The vomiting,fever,abdominal pain relief time and length of hospital stay in the observation group were (5.12 ±0.52)d,(1.52 ±0.33)d,(1.32 ± 0.41)d,(4.73 ±0.55)d,(5.95 ±0.52)d respectively,which of the control group were (10.33 ±0.64)d,(2.62 ± 0.47)d,(2.21 ±0.32)d,(10.06 ±1.67)d,(11.05 ±1.42)d respectively,which of the observation group were significantly shorter than the control group.The effective rate of the observation group was 97.33% (73 /75),which of the control group was 84.00% (63 /75),the difference between the two groups was statistically significant(χ2 =8.324,P <0.05).Before treatment,the TNF -ɑ,IL -6,IL -10 levels had no obvious differences between the two groups,after treatment,those in the observation group were (2.08 ±0.24)ng/mL,(94.67 ±10.75)ng/mL,(7.58 ± 0.88)ng/mL respectively,those in the control group were (2.88 ±0.37)ng/mL,(128.55 ±17.53)ng/mL,(40.55 ± 1.12)ng/mL respectively,and the levels of the observation group were better than the control group,the differences were statistically significant (t =6.327,5.694,4.156,all P <0.05 ).Conclusion Microecologic modulator combined with antibiotic in treatment of infantile diarrhea can significantly shorten the recovery time of clinical symptoms,reduce inflammation,improve the treatment effect,it is worthy of clinical popularization and application.

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.

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.

Objective: To investigate the curative effect of combined acupuncture and medicine on pseudobulbar paralysis. Method:The patients were allocated into an acupuncture group of 50 cases and a control group of 48 cases by completely random sampling. 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.

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.

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.

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.

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.
