1.Adrenomedullin and cardiovascular remodeling
Chinese Journal of Pathophysiology 1989;0(05):-
Adrenomedullin (AM) is a novel vasoactive peptide. The actions of AM include vasodilatation, reduction of arterial pressure, inhibition of vascular smooth muscle cell transference and proliferation, diuretic and natriuretic, inhibition of aldsterone secretion. Furthermore AM modulates extra cellular matrix deposition. So adrenomedullin plays an important role in the regulation of cardiovascular remodeling. This paper reviews the relationship between AM and cardiovascular remodeling.

Objective To evaluate the effect of percutaneous coronary intervention (PCI) on left ventricular function in patients with different types of myocardial infarction and to explore the correlation factors for the left ventricular function.Methods A total of 43 patients diagnosed as acute myocardial iffarction were enrolled in this study.The perfusion and delayed enhancement magnetic resonance imaging (DE-MRI) was applied to observe the following parameters before the PCI and at month 6 after the procedure:infarct mass,left ventricular ejection fraction (LVEF) and abnormal wall motion score.The subjects were divided into the following three groups by the transmural extent of myocardial infarction manifested in the DE-MRI:the transmural enhancement group,the nontransmural group and the mixed group.Laboratory test was done to detect the level of endothelin (ET),matrix metal enzyme 9 (MMP-9) and high sensitive C reactive protein (hsCRP) before PCI and at month 6 after the procedure.The t test was used to compare the differences among the groups and the multiple regression analysis was taken to explore the correlation factors for the left ventricular function.Results Compared with the parameters before PCI,the infarct mass after PCI significantly decreased in the nontransmural group and the mixed group [(4.0 ± 2.9) g/cm3 vs (9.8 ±5.6) g/cm3 and (6.0 ±3.5) g/cm3 vs (11.8 ±6.2) g/cm3,all P <0.05],while LVEF was significantly improved after PCI in both groups [(52.6 ± 15.4) % vs (41.9 ± 16.3) %,(45.6 ± 15.4)% vs (38.9 ± 16.3)%,all P <0.05].The infarct mass was an independent correlation factor for LVEF before PCI (RR =0.318,P <0.05) and LVEF after PCI(RR =0.293,P <0.05).LVEF before PCI was independently correlated with the level of hsCRP (RR =0.318,P < 0.05).Conclusion The effect of PCI on the improvement of left ventricular function differs in patients with different extent of myocardial infarction,which is correlated with the amount of survival myocardium and the inflammatory factors.

OBJECTIVE:To systematically review the effect of organic cation transporter 2 [(OCT2)808G>T] gene polymor-phism on the metformin hydrochloride pharmacokinetics in vivo,and to provide evidence-based reference for clinical medication. METHODS:Retrieved from PubMed,EMBase,Foreign Medical Journey Service,CJFD,VIP database and Wanfang database,re-lated studies about the effect of (OCT2)808G>T gene polymorphism on the metformin hydrochloride pharmacokinetics in vivo were collected,and Meta-analysis was performed by using Rev Man 5.1 statistics software. RESULTS:A total of 5 retrospective studies were included,involving 172 patients. The result of gene type was type GT,type TT and type GG. Results of Meta-analysis showed,compared with type GT volunteers,type TT could prolong the half-time period of metformin hydrochloride;compared with type TT,type GG could increase the peak concentration. However,(OCT2)808G>T gene polymorphism had no effects on the renal clearance rate,creatinine clearance rate and area under the drug-time curve. CONCLUSIONS:(OCT2)808G>T gene poly-morphism has certain effect on the half-time period and peak concentration of metformin hydrochloride in vivo of health volunteer, and has no effect on the renal clearance rate,creatinine clearance rate and area under the drug-time curve. Due to the limit of re-search methodological quality,large-scale and high quality studies are required for further validation of the conclusions.

Objective:To statistically analyze the prescription writing norms of narcotic drugs for injection in the operation room and inpatient area of our hospital to improve the prescription writing quality and the efficiency of management. Methods:A retrospec-tive research method was adopted, and 17 103 prescriptions for narcotic drugs for injection in the operation room and inpatient area were collected and analyzed from June to August in 2014. Results:The irregular proportion of prescriptions of narcotic drugs for injec-tion was 9. 05%, and the abnormal item was lack of the text. The proportion of prescriptions using residual amount and needing to be marked was 4. 01%. Conclusion: Improving the management and unifying the prescriptions of narcotics, or applying the electronic prescription if allowed will improve the quality of prescriptions of narcotics and achieve the purpose of fine management.

Objective:To investigate the residual narcotics for injection after used in wards in order to provide evidence for the use standardization of narcotics for injection. Methods:A retrospective research method was adopted. Totally 5 288 prescriptions including narcotic drugs for injection in wards were collected and analyzed from June to August in 2014. Results:Only four kinds of narcotics for injection were used in wards, the residual proportion of morphine hydrochloride injection and pethidine hydrochloride injection was 2%, and that of fentanyl citrate injection was 0. 2%. Conclusion:The residue of narcotics for injection in wards is very little, and the specifi-cations of the medication in our hospital meet the demands of clinics. The research is beneficial to improving the management efficiency.

Objective To identify a clinical isolate of Mycobacterium abscessus.Methods A pus sample was collected from a patient with suspected nontuberculous mycobacterial infection who visited the Affiliated Hospital of Weifang Medical University on December 18,2017,and was subjected to bacterial culture,Gram staining and acid-fast staining.Drug sensitivity test was conducted by the proportion method.The genome DNA of the strain was extracted and amplified by PCR with the universal primer of 16S rRNA.The PCR products were sequenced after collection and purification,and were compared with the known sequence of Mycobacterium abscessus in GenBank database.The isolate was identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).Results The clinical isolate was identified as Mycobacterium abscessus both by MALDI-TOF MS and 16S rRNA gene sequencing.The drug sensitivity test showed that the strain was sensitive to amikacin,moxifloxacin,levofloxacin,but was resistant to streptomycin,isoniazid,rifampicin,ethambutol,ofloxacin,kanamycin,capreomycin,aminosalicylic acid,protionamide and rifabutin.The patient was diagnosed with subcutaneous soft tissue infection in the left knee joint.According to the results of drug sensitivity test,the patient was treated with amikacin and levofloxacin,and her condition was improved after treatment.Conclusion The 16S rRNA gene detection and MALDI-TOF MS both can be applied in the identification of Mycobacterium abscessus.

Hookworm infections are rare causes of acute gastrointestinal bleeding. We report a middle aged man with primary nephrotic syndrome and pulmonary embolism. During the treatment with steroids and anticoagulants, the patient presented acute massive hemorrhage of the gastrointestinal tract. The results of gastroscopy showed red worms in the duodenum. Colonoscopy and CT angiogram of abdomen were unremarkable. Capsule endoscopy revealed fresh blood and multiple hookworms in the jejunum and ileum. Hookworms caused the acute intestinal bleeding. The patient responded well to albendazole. Hematochezia was markedly ameliorated after eliminating the parasites. Hence, hookworm infection should be considered in the differential diagnosis of a patient with obscure gastrointestinal bleeding. Capsule endoscopy may offer a better means of diagnosis for intestinal hookworm infections.
