结石形成

The expressions of MUC1, MUC3 were not synchronization in different lesions of cholecyst.

结论MUC1和MUC3在结石性胆囊炎及胆囊腺瘤样息肉中的表达呈负相关，这可能与结石形成及胆囊癌前病变有关。

Caffeine can promote cholecystokinin, thus preventing the formation of gallstones in the gallbladder.

咖啡因能促进胆囊收缩，从而防止在胆囊结石形成。

The ingredients of crystalloid and pH were detected.

结论大量饮食猪瘦肉可导致尿pH值和尿晶体成分变化，可能是尿结石形成的重要原因之一。

Objective To study the effects of glucose and lipid metabolism on gallstone formation.

目的 探讨糖脂代谢在胆囊结石形成中的作用。

The structure of oolite layers and the recrystallization and replacement of concretes can be used to make comparative explanatio of the formation mechanism and growth genesis of uro-lith stones.

沉积鲕石、核形石的分层结构和再结晶交代现象等，可以对比应用于尿石的形成和发育机理的解释；同时，尿路结石形成理论中的局部过饱和以及取向附生学说，也可引进于沉积鲕石、核形石和结核的形成理论中。

It was shown that the main compositions of the stones were uric acid dehydrate and ammonium urate, so we derived the mechanism of stone formation from the metabolic process of the two stone compositions, meanwhile, we raised some advices on the diagnosis and the treatment of the disease.

目前已知，这种结石的成分主要是二水尿酸和尿酸铵，所以本文通过这两种成分的代谢过程来逆向推导这种特殊结石形成的过程，同时也提出一些相关的诊断和治疗上的建议。

Conclu sion: The ethyl acetate elution of ethyl acetate fraction extract of Alisma orientalis can significantly inhibit urinary calcium oxalate stone formation in rats and be the most effective constituent of Alisma orientalis .

泽泻醋酸乙酯浸膏的醋酸乙酯洗脱液能抑制实验性高草酸尿症大白鼠体内肾草酸钙晶体的形成，是泽泻抑制尿草酸钙结石形成的有效部位。

T tube drainage was able to decrease bile viscosity effectively.The number of bacteria decreased significantly until 21 postoperative days.The time that T tube is drawn out is on 14 postoperative days.Bacteria may exist in bile continuously and play a role on relapse of choledochitis and bile duct stone.

胆汁中的细菌和粘度升高在胆管结石形成中起协同作用。T管引流能有效地降低胆汁粘度，而胆汁中细菌量在引流术后第3周才有显著减少，临床2周时拨除T管细菌可潜伏下来，对胆管炎和胆管结石的复发可能起作用。

As the results showed that the significant relation between TCBA and calcium or magnesium, mainly between glycocholic, glycochenocholic or taurocholic acids and calcium or magnesium, could be found in all three groups but there was not any obvious relation between TCBA and ferrum or zinc except between glycocholic acid and zinc in gallbladder stone group.

由此可见前列腺素在胆结石形成中占有重要地位。花生四烯酸是合成前列腺素的前体，它在环氧化酶作用下形成前列腺素。本研究证实在成石性胆囊胆汁中花生四烯酸的含量（0.09%）和阳性率（71.74%）明显高于对照组（0.02%，21.42%），P.05。说明成石性胆汁为合成前列腺素提供了前体物质。

Objective To study the etiology and preventive measures of urethral calculus after the urethroplasty of hypospadias.

目的 回顾25年来尿道下裂术后出现尿路结石病例，探讨尿路结石形成原因、机制及其预防措施。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
