2.Effcts of the panaxadiol saponins on serum 5-HT and platelets in dog with hemorrhagic shock
Chinese Journal of Pathophysiology 1986;0(01):-
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.
3.Review of recommendations for dietary intake of cholesterol based on various guidelines
Chinese Journal of Health Management 2017;11(1):29-33
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.
4.Detection of CGRP receptor in rat bone marrow mesenchymal stem cells and its induced osteoblasts
Orthopedic Journal of China 2006;0(04):-
[Objective]To compare the expression of calcitonin gene-related peptide(CGRP) receptor in rat bone marrow mesenchymal stem cells(rBMSCs) and the induced osteoblasts.[Method]The rBMSCs were isolated using whole bone marrow adherence method,and classified into osteoblast-induced group and non-induced group.In the different periods of culturing(1,2,and 3 weeks),identification of osteoblasts was performed by immunohistochemistry and reverse transcriptase-polymerase chain reaction(RT-PCR),and expression of the CGRP receptor was detected by Western Blot and RT-PCR.[Result]RT-PCR test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point,expression of CGRP receptor was increased in a time-dependent manner in the osteoblast-induced groups.Western Blot test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point.Expression of CGRP receptor was increased in a time-dependent manner in osteoblast-induced groups.[Conclusion]According to the mRNA test and protein test,it is suggested that CGRP receptor exists in the rBMSCs.CGRP receptor expression increased in the progress of osteogenic differentiation.
5.The comparison of genetic susceptibility of type 1A diabetes mellitus between Asian and Caucasian populations
Journal of Medical Postgraduates 2003;0(10):-
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.

Fudan University Journal of Medical Sciences 2009;36(6):760-763
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.
