Experiments were performed on 29 healthy mongrel dogs with average body weight of 13?2.2kg. The animals were randomly divided into three groups:(1) nine dogs in the hemorrhagic shock group(HS); (2) tendogs in the panaxadiol saponin pretreatement group (HSG), which were intravenously injected with 25mg panaxadiol saponin 1 h before bleeding; (3) In the dexamethasone pretreatment group, othet ten dogs were intramuscularly injected with 1 mg/kg body wt of dexamethasone 1 h before bleeding. The mean arterial pressure of 5.3 kPa was kept during experimental period. The morphological changes of platelet were observed with scanning electromicroscope. The results showed that the platelet damage was much lighter in HSP and HSD gnoups than that of the HS group. The seum 5-HT content of HS group gradually increased hemorrhage with time delay. In the HSG group,the 5-HT level was increased from 1 and 3 h after bleeding,then it was decreased at 4 and 5 h. In the HSD group 5-HT level didn′t show any change from prebleeding to postbleeding. However, in the HS group 5-HIAA concentration increased significantly from 3rd to 5th hour after bleeding in the HS group,but was not in the HSG and HSD groups. These findings suggest that the panaxadiol saponins and dexamethsone can effecti vely inhibit the increasing of 5-HT and 5-HIAA levels in the themorrhagic shock.

Objective To explore the clinical and pathological characteristics of ovarian endometriosis and malignant cases, and to improve our recognition of this disease. Methods A total of 1 289 cases of ovarian endometriosis were divided into two groups: the benign group (1 275 cases)and the malignant group (14 cases). They were analyzed on: dysmenorrhea, infertility, features of ultrasound examination,site of tumour,pathological types and complications. Results Malignancy arising from ovarian endometriosis was 1.09%. As far as degree of dysmenorrhea, size of cyst >10 cm, CA125 >500 U/L, features of ultrasound were concerned, difference between the two groups was statistically significant. Conclusions In the present study, the malignant rate of ovarian endometriosis was about 1%. Malignancy should be considered seriously when the following situations occured: change in the degree of dysmenorrhea, size of cyst larger than 10 cm, CA125 higher than 500 U/L, mamilla observed by ultrasound examination.

Some human leucocyte antigens(HLA),espeually class Ⅱ genotypes such as HLA DQ/DR are closely linked to type 1A diabetes mellitus(T1ADM).But the genetic susceptibility of HLA DR/DQ are different between Caucasian and Asian populations.The aspartic acid at position 57 of DQ? can not confer resistance to T1ADM in Asians.DQ2 and DQ8 are the well-known susceptible genotypes in Caucasians while DQ4 and DQ9 are in Asians.An unexpected high risk of T1ADM is observed for the linkage disequilibrium between DRB1*0301/ DRB1*0401 and DQ2/DQ8 in both the populations.The DQB1*0302,DQA1*0501,DRB1*0401,*0402,*0407 are associated with T1ADM in Caucasians,but it is not the case in Asians.In contrast,DQB1*0401 shows a positive association to T1ADM in Asians,has a protective effect against T1ADM in Caucasians.Additionally DRB1*09 could be another susceptible gene in Asians.

Objective To investigate the effect of transverse incision surgery for epicanthoplasty with double eyelid fold reconstruction. Design Retrospective case series. Participants 103 patients with epicanthus. Method Transverse incision was applied for epicanthoplasty in all patients, and incorporated with double eyelid fold reconstruction. Patients were followed up 3-6 months. Main Outcome Measures Size of lacrimal caruncle, length of palpebral fissure, inner canthic diameter and scarring degree. Results Lacrimal caruncle was revealed 3/4 merous in 21 cases, 2/3 merous in 56 cases, 1/2 merous in 8 cases. Extent of palpebral fissure was 30-31mm in 5 cases, 28-29 mm in 69 cases, 26-27 mm in 11 cases. Inner canthic diameter was 32-33mm in 61 cases, 30-31 mm in 23 cases, 29 mm in 1 case. The scarring was little in 56 cases, obviously in 29 cases. Epicanthus relapsed in 2 cases. 16 cases lost follow-up. Conclusion Transverse incision surgery for epicanthoplasty with double eyelid fold reconstruction has less tissue damage and minimal scarring produced at the medial cantha. It is a simple and reliable surgical approach for correction of epicanthus.

In recent years, there is much debate on how much cholesterol should be taken in with diet. This article reviews the dietary guidelines, recommendations, and strategies of some national and international organizations since the mid-20th century. The dietary cholesterol was systematically combed and interpreted on its intake for the general population and special population. We would like to help the professionals and public better understand the meaning of the guidelines, to eliminate the misunderstanding of dietary cholesterol and to establish the correct concept of healthy eating pattern.

Objective To explore the production of medical polypropylene anti-bacterial mesh coated with triclosan,and study the properties of its controlled-release drugs,as well as the efficiency of the mesh coated with triclosan.Methods A medical polypropylene anti-bacterial mesh coated with triclosan was produced by the method of solvent evaporation,with triclosan as antibacterial agent and ethylene-vinyl alcohol copolymer as carrier.The meshes were divided into four groups: A,B,C and D.The meshes in A,B and C(experimental) groups were coated with triclosan,and D group was control group.The ultrastructure of meshes of the 4 groups was observed under electron microscope.The slip diffusion method was used to observe the diameter of bacteriostasis-rings in different time periods.At the same time,we observed the maximum tensile strength of the mesh in transverse and longitudinal axis when they were pulled off before and after the experiment.Results The surfaces of B group were uniform and smooth,and the coating could continuously release drugs during 7 days in sodium chloride.The diameter of bacteriostasis-rings in B group was significantly larger than that in control group(P

Objective:To prepare type Ⅲ sodium-phosphate cotransporter(NaPi-Ⅲ) siRNA-loaded chitosan microspheres and to evaluate their physico-chemical properties and siRNA release in vitro.Methods: NaPi-Ⅲ siRNA was loaded into chitosan microspheres by using the complex coacervation method.The structure of the nanoparticles was observed under scanning electron microscope and their diameter distribution was measured by a laser grain analyzer.RNase assay was used to detect the efficacy of anoparticles in prevention of siRNA from degradation.Ultraviolet spectrophotometry and HPLC technique were used to determine the entrapment efficiency,loading capacity,and siRNA releasing rate in vitro.Results: The chitosan nanoparticles loaded with NaPi-Ⅲ siRNA were successfully prepared.The nanoparticles were spherical in shape and were well distributed,with an average diameter of 173 nm.After RNase treatment,D_(260) rose more slowly in chitosan nanoparticles-based siRNA suspension than in simple NaPi-Ⅲ siRNA solution(P
