This paper firstly analyses the sales and purchase contracts in the procurement of drugs in public hospitals, and then points out the market failure in the two contracts. After the implementation of administrative measures such as government pricing, administrative price reduction, price increase, centralized bidding and purcha-sing, various drug procurement stakeholders have adopted various game behaviors, and government procurement and price formation have appeared in government hospitals, not-neglecting the formation of the price ofGovernment fail-ure. The future price formation in public hospitals should be the market pricing under the limited government regu-lation, and increase the medical insurance institutions' price negotiation and the public hospitals' participation degree in the bidding process based on maintaining the centralized bidding and purchasing and zero administrative rate.

Niclosamide is the most commonly used molluscicide. Along with a lot of application of niclosamide more and more scientists studied its toxic effects to aquatic organisms as well as the related cell toxicity mechanism. This paper summariz?es the toxicity on cell organelle enzyme cell signaling pathway and genetic material caused by niclosamide and puts for?ward the future research direction.

Plasma Limulus Lysate assay, fibronectin, blood coagulation picture (Fbg, FⅡ, HPT, PT, ⅧR:Ag) and antithrombin-Ⅲ were determined in G1 patients with liver disease. The frequency of endotoxemia depended upon the degree and extent of hepatic injury and the phagocytic activity of the Kupffer cells. The coagulation abnormalities were multifactorial, there were not only the changes of clotting proteins, but also the diminution of antithrombin-Ⅲ. Multivariate analysis showed that the frequency of endotoxemia was closely correlated with the changes of fibronectin, clotting proteins and antithrombin-III (P

This article evaluates the necessity and possibility of endoscopic surgery training in medical undergraduates and designs a simple,suitable platform and exercise for the training.

Objective To assess the rationality of using CT for clinical staging in esophageal carcinoma.Methods 103 esophageal carcinoma patients with radical resection were selected,patients were examined by CT before surgery.To compare the clinical staging on the basis of CT findings with pathology.Results Lymph node enlargement were mentioned in 29 cases (28.2 ％) with CT findings before surgery,but 70 cases (68.0 ％) by pathology.The CT findings and pathology were inconsistent (x2 =11.719,P =0.001).Although the pathology staging in the cases which were positive with CT findings could be later (Z =-3.04,P =0.002),there was no correlation between the two methods (x2 =10.885,r =0.055,P =0.055).Conclusion The accuracy rate in esophageal carcinoma clinical staging by CT before surgery is low.Combining with PET-CT or endoscopic ultrasonography may improve the accuracy rate.

Pancreaticoduodenal anastomotic dehiscence complicated with peritoneal hemorrhage following pancreaticoduodenectomy is a serious complication which threatens patients'life.Prevention and mangement of pancreaticoduodenal anastomotic dehiscence and peritoneal hemorrhage is the focus in the surgical treatment.Operation is the most reliable treatment for bleeding.While reoperation is difficult for most surgeons and the risk of fistula and rebleeding after reoperation exist.Some procedures will affect the endocrine and exocrine function of pancreas.We applied pancreaticojejunal bridge drainage for most patients with hemorrhage after pancreaticoduodenectomy.This procedure is easy,safe,and can protect the pancreatic function.

ObjectiveTo observe the lesions of psoriasis vulgaris by confocal laser scanning microscopy(CLSM).MethodsThe typical lesions of 120 patients with psoriasis vulgaris were observed by CLSM,and scanning results were recorded.ResultsOf the 120 patients with psoriasis vulgaris,all (100％)had dilated and twisted capillaries in dermal papillae,113 (94.17％) acanthosis,106 (88.33％) parakeratosis,86 (71.67％) Munro microabscesses at the level of stratum corneum,71(59.17％) diminished or disappeared stratum granulosum.There were a few(1 to 2) dilated capillary lumens in papillary dermis,with no obvious reduction in the distance between dermal papillae.Some dermal papillary rings lost their integrity or brightness slightly in 24 of the 27 patients with psoriasis guttata.The height of stratum spinosum was 96.85 ± 17.88 μm (ranged:80-150 μm) in patients with psoriasis guttata,lower than that in those with plaque psoriasis (average:143.45 ± 23.19 μm,range:100-190 μm).In lesions of plaque psoriasis,the capillaries in dermal papillae were apparently dilated with hyperemia,showing a characteristic'S' shape or horseshoe appearance; the diameter of dermal papillae was increased and the distance between dermal papillae was reduced,giving a 'transverse section of lotus roots' appearance.Dermal papillary rings completely disappeared in 25 of the 29 patients with plaque psoriasis.ConclusionCLSM may serve as an aid in the diagnosis of psoriasis vulgaris.
