Portal vein arterialization can prevent isehemia and damage of liver and fill portal vein with arterial blood. This article is a review about clinical applications and problems of portal vein arterialization which is used in liver transplantation and surgical therapy for portal hepatic tumor, portal hypertension and acute liver failure.

Objective To investigate the effects of the EGF on isolation and cloning of mouse embryonic stem-like cells from PGCs. Methods EGF with different density were added to the culture medium of cells .After a culturing period ,the cloning number of mouse embryonic stem-like cells and the topmost passage would be observed and registered. Results There was not obvious effects on the primary culture of mouse ESC and was distinct on the later passage if EGF were used. Conclusions In the primary passage of mouse ESC may survive without EGF,and the impact of the existence of EGF was better than the one of the inexistence to the cloning of mouse ESC.

Objective To evaluate the middle and long term effects of the two-stage procedures of drilling for hydroxyapatite orbital implant and inserting a motility peg, and to investigate the pathogenesis and treatment of the various complications during the procedure. Methods This retospective study included 68 patients who had underwent the drilling of the hydroxyapatite and motility peg placement for over 3 years. Mean age at operation was 30.7 years (range from 17～60 years). All patients were placed plastic peg. Information recorded included pre-and post-operative facial appearance, motility of the artificial eye, conjunctival sac discharge and other complications. Results No secondary infection occured in 36～72 months of follow up. All patients felt that there had been an improvement in the motility of their artificial eye. And their cosmetic appearance was acceptable. The most frequent complication encountered was discharge from conjunctiva sac, which occurred in 31 patients. Extrusion of the motility peg was found in 6 patients. 5 patients had exuberant granulation in conjunctiva sac. Conclusion Drilling of the hydroxyapatite implant improves both the appearance and the motility of the artificial eye. Complications are minor and can be easily prevented and treated. The vascularization of HA sphere with good motility should be drilled at relatively larger conjunctival sac in the patients who can cooperate under local anesthesia.

Objective To evaluate the clinical effect of Medpor ( porous high density polyethylene )as a padding material in correction of sunken eyelid after hydroxyapatite (HA) implantation. Methods We used Medpor in 17 patients ( 10 male and 7 female ), aged from 18 to 43 years (mean 26.6 years ), in which 9 cases had concomitant orbital fractures. The Medpor was implanted after HA sphere implantation ranged from 2 to 19 months ( average 6.7 months ). 17 consecutive patients with implantation of HA sphere were filled with Medpor under the periosteum. All of the cases were examined by CT scanning to distinguish orbital lesions with or without fracture. In the orbital fracture cases, we first repaired orbit bone defects with Medpor. Results There were no secondary infection or implant rejection occurred after following up for 1 to 18 months (average 8.7 months ). All patients' cosmesis was acceptable. 14 of 17 patients gained symmetric appearance. Although 3 patients had slight sunken eyelid, they gained a dramatic improvement of facial appearance nevertheless. Conclusions Sunken eyelid after HA sphere implant is related with orbital fracture as well as relative reduction of orbital content. Medpor presents fine biological compatibility. It is also easy to remodel and fix during operation. Medpor is a good implant for treatment of sunken eyelid after HA sphere orbital implantaion. [

It is one of the important tasks to promote the development of traditional Chinese medicine culture crea-tive industry in constructing the culture-rich Shandong Province. The major factors that influence the development of traditional Chinese medicine culture creative industry in Shandong Province and the ranks of their importance were thus analyzed by questionnaire survey and hierarchy analysis, respectively. Certain suggestions were put for-ward for the development of traditional Chinese medicine culture creative industry in Shandong Province.

Hierarchical diagnosis and treatment system has become one of the strategies for overcoming the diffi-culties in medical reform in our country. The important role of health information and its application in hierarchical diagnosis and treatment were thus elaborated in this paper in order to provide reference for the health information construction in establishing hierarchical diagnosis and treatment system at different levels in our country.

Objective We tried to design a Instructor Rating Scale Identified by Nursing Students,and then evaluate its rehability and validity.Methods The original item pool was formulated by investigating 351 nursing students with convenience samphng method to develop a prehminary scale.Then it was used to investigate 273 nursing students to test its rehability and validity.Results The formal scale consisted of six dimensions,which contained 19 items.The cumative contribution rate of these dimensions was 62.30％.The Cronbach's α coefficient was 0.54,test and re-test reliability was 0.48.Conclusions The Instructor Rating Scale Identified by Nursing Students can be applied to evaluate the instructors by nursing students.

The paper objectively analyzes the opportunities and challenges of Internet + medical,and puts forward relevant strategies and recommendations for deeply integratingInternet +into the traditional medical industry in several aspects,including strengthening the construction of Internet infrastructure in the medical industry,regulating the market access and improving the industry standards,as well as establishing and improving relevant supporting laws,regulations and policies.

Serum 25-(OH)D3concentration was determined in subjects with different types of obesity. The serum 25-(OH)D3levels in overweight or obese and central obese subjects were lower than that in non-obese subjects.(P＜0.01). In a multiple linear regression analysis serum 25-(OH)D3was independently and negatively correlated with body mass index and waist circumference.

ObjectiveTo observe and compare the efficacy of two types of microencapsulated rat islets xenotransplanted into diabetic mice. MethodsThe mice diabetic model made with injecting 3% Streptozotosin through tail vein. Four groups were assigned: control group, naked islet transplantation group, alginate-BaCl2 microencapsulated islet transplantation group, agarose-PSSa microencapsulated islet transplantation group.300 islets were transplanted under the renal envelope of each diabetic mice respectively. ResultsThere were no significant difference in mean level of the blood glucose before transplantation among four groups. One week after transplantation, the respective mean level of the blood glucose in four groups were (7.26±1.56) mmol/L in alginate-BaCl2 microencapsulated islet transplantation group, (7.14±1.04) mmol/L in agarose-PSSa microencapsulated islet transplantation group, (7.42±1.52) mmol/L in naked islet transplantation group and (22.54±1.24) mmol/L in control. There were significant difference between the two encapsulated islet groups and the other two groups. The survived period of the two encapsulated islet transplantation groups were longer than that of the other two groups. The survived period of the alginate-BaCl2 microencapsulated islet transplantation group was longer than that of the agarose-PSSa microencapsulated islet transplantation group (92 d vs 56 d),the same as the time of keeping nomal blood glucose level (76 d vs 41 d). ConclusionMicroencapsulated rat islets with this two materials can survive in diabetic mice with their biological activity, and the alginate-BaCl2 microcapsules are better than the agarose-PSSa microcapsules.
