继发性甲状旁腺功能亢进(SHPT)是慢性肾衰竭的常见并发症之一,1,25-二羟维生素D3(1,25-dihydroxy vitamin D3,1,25-(OH)2-D3)和成纤维细胞生长因子23(fibroblast growth factor 23,FGF23)水平异常及其受体表达下调、钙磷代谢紊乱是SHPT的重要发病机制。鉴于上述发病机制,磷结合剂、活性维生素D和钙敏感受体激动剂等被广泛运用于治疗SHPT。近年来上述药物不断被深入研发并取得良好疗效,对于药物治疗效果不佳的SHPT,甲状旁腺切除术、超声引导下局部注射介入疗法成为有效的治疗手段。在SHPT的治疗过程中,血清钙、磷、全段甲状旁腺激素(iPTH)、25-羟维生素D[25(OH)D]、碱性磷酸酶(ALP)等的监测也非常重要,有利于指导用药及评估疗效。

There are limited data on celiac disease(CD) from *** limited knowledge about CD in India might be attributed to several *** fi rst meeting of the Indian Task Force for Celiac Disease was held in the Asian Institute of Gastroenterology,Hyderabad,India in December *** objectives of the meeting were to focus research on prevalence of CD in the wheat-eating Northern vs the rice-eating Southern Indian population,low-budget serological assays to study the underprivileged population,to involve other medical subspecialties in CD,to suggest proper legislation regarding wheat food labeling,and to organize affordable food substitutes for patients with celiac disease.

Joining of AZ31 and AZ91 Mg alloys by friction stir welding

引用

Journal of Magnesium and Alloys 2015年第4期3卷 330-334页

作者： B.Ratna Sunil G.Pradeep kumar reddy A.S.N.Mounika P.Navya Sree P.Rama Pinneswari I.Ambica R.ajay Babu P.Amarnadh Department of Mechanical Engineering Rajiv Gandhi University of Knowledge Technologies(AP-IIIT)Nuzvid 521202India Department of Mechanical Engineering Vignana Bharathi Institute of TechnologyHyderabad 501301India

Two dissimilar magnesium(Mg)alloy sheets,one with low aluminium(AZ31)and another with high aluminium(AZ91)content,were successfully joined by friction stir welding(FSW).The effect of process parameters on the formation of hot cracks was investigated.A sound metallurgical joint was obtained at optimized process parameters(1400 rpm with 25 mm/min feed)which contained fine grains and distributed β(Mg_(17)Al_(12))phase within the nugget *** increasing trend in the hardness measurements has also confirmed more amount of dissolution of aluminium within the nugget zone.A sharp interface between nugget zone and thermo mechanical affected zone(TMAZ)was clearly noticed at the AZ31 Mg alloy side(advancing)but not on the AZ91 Mg alloy side(retreating).From the results it can be concluded that FSW can be effectively used to join dissimilar metals,particularly difficult to process metals such as Mg alloys,and hot cracking can be completely eliminated by choosing appropriate process parameters to achieve sound joint.

Per oral cholangiopancreatoscopy in pancreatico biliary diseases- Expert consensus statements

引用

World Journal of Gastroenterology 2015年第15期21卷 4722-4734页

AIM: To provide consensus statements on the use of per-oral cholangiopancreatoscopy(POCPS).METHODS: A workgroup of experts in endoscopic retrograde cholangiopancreatography(ERCP), endosonography, and POCPS generated consensus statements summarizing the utility of POCPS in pancreaticobiliary disease. Recommendation grades used validated evidence ratings of publications from an extensive literature ***: Six consensus statements were generated:(1) POCPS is now an important additional tool during ERCP;(2) in patients with indeterminate biliary strictures, POCS and POCS-guided targeted biopsy are useful for establishing a definitive diagnosis;(3) POCS and POCS-guided lithotripsy are recommended for treatment of difficult common bile duct stones when standard techniques fail;(4) in patients with main duct intraductal papillary mucinous neoplasms(IPMN) POPS may be used to assess extent of tumor to assist surgicalresection;(5) in difficult pancreatic ductal stones,POPS-guided lithotripsy may be useful in fragmentation and extraction of stones; and(6) additional indications for POCPS include selective guidewire placement,unexplained hemobilia, assessing intraductal biliary ablation therapy, and extracting migrated stents. CONCLUSION: POCPS is important in association with ERCP, particularly for diagnosis of indeterminate biliary strictures and for intra-ductal lithotripsy when other techniques failed, and may be useful for preoperative assessment of extent of main duct IPMN, for extraction of difficult pancreatic stones, and for unusua indications involving selective guidewire placement,assessing unexplained hemobilia or intraductal biliary ablation therapy, and extracting migrated stents.
