1.CLINICAL SIGNIFICANCE OF BACTERIAL COUNT OF SUBESCHAR TISSUE
Academic Journal of Second Military Medical University 1981;0(03):-
The relationships between 105 bacterial counts of subeschar tissue of 40 burn cases and the success of failure of skin autografting are analysed in the present article.Data showed that the success rate of skin grafting was only 94.72% when there was no subeschar bacterial growth, and 90% even while the bacterial count of subeschar tissue reached 1010.This suggests that there are many factors influencing the success or failure of skin grafting.The bacterial count of subeschar tissue is one but not an unique determining factor .Therefore, it can not be used as a predicting factor of success or failure of skin grafting.The notion that subeschar bacterial count of 106 is a watershed of success or failure of skin grafting may lead to its misunderstanding for a contriandiction of skin grafting.Thereby the active treat- ment of local burn Woun wound will be influenced .This problem needs further deliberation.
2.AN EXPERIMENTAL STUDY OF MESENTERIC MICROCIRCURATION OF BURNED RAT
Academic Journal of Second Military Medical University 1983;0(S1):-
The early changes in microcirculation of burns are of significant pathophsi-ologic importance. The experimental use of cimetidine, an antagonist of histamine H2-receptor, demonstrated its better effectiveness against the changes in microva-scular permeability. No observations on blood flowing state were made. The post-burn adherence of White blood cells to venules were noted recently by Eriksson, which was considered as a pathophysiologic mechanism of postburn tissue edema.A 20% body surface area third degree burn is produced in rats, which is designed an experimental model for observation of the changes in mesenteric microcirculation and a comparative relationship between the adherence of white blood cells and the tissue water content, a comparative therapeutic effect of early resuscitation with Ringer's lactate solution and the results of blood flow in microcirculation, adherence of white blood cells, and aggregation of red blood cells obtained by administration of cimtldine.The chief findings of mesentery microcirculation of burned rat are venule dilatation with progressive slowing and sludging of blood flow; preipheral rotation and adherence of white blood cells; progressive aggregation of red blood cells. No edema is found by measuring water content of remote tissue, better therapeutic effects are shown both by resuscitation of fluid and administration of cimetidine, with the former in predeminanee. The present study indicates:1.Hypovolemia caused by postburn fluid loss and venule dilatation is a major factor leading to worsening of microcircuration blood flow. In order to maintain normal flow state, to assure abetter tissue perfusion, the administration of cimetidine associated with fluid resuscitation may be beneficial.2.Low flow state of microcirculation is the underlying cause, but not the only one of adherence of white blood cells postburn.3.Adherence of white blood cells within venules does not lead to tissue edema, it is, therefore, not the cause of remote tissue edema. The point of view of Eriksson merites further discussion.4.The problems of aggregation of red blood cells and remote unburned tissue edema are also discussed in the present artical. The primary danger of aggregation of red blood cells is to make worsen of the microcirculation, which aggravates the deficiency of blood and oxygen; timely correction of hypovolumia is a preventive measure of primary importance. The experimental model revealed that if no fluid is administered, some, then shows slightly mild dehydration. This might probably be due to the compensatory responce of the remote area to hemoconcen-tration.

In this study, 119 adult wistar rats were used, and divided into four groups (control group, burn group, burn-cimetidine treatment group and burn-ranitidine reatment grup). 20% TBSA full thickness burn was produced by immersion of the clipped back of the rat in 100℃ boiling water for 15s. The rats of the control group were immersed in 37℃ water for 15 s. In the treatment groups, the animals were treated with cimetidine (0.1 mg/g) or ranitidine (0.05 mg/g) intraperitoneally every 12 h, respectively. All animals were given fluid therapy according to the TBSA and body weight. In the animals treated with cimetidine or ranitidine, the H+ concentration of gastric juice was greatly decreased as compared with that of the burn group (P
5.Imaging studies of multiple sclerosis: Hemodynamics and changes in oxygen metabolism
Chinese Journal of Medical Imaging Technology 2017;33(6):805-809
The relationship between neuronal inflammatory changes and extensive neurodegeneration in patients with multiple sclerosis (MS) remains to be studied.Recent neuroimaging studies have shown that energy depletion due to the impairment of effective oxygen metabolism and oxygen supply defects may be one of the causes of neurodegeneration.In this paper,the pathologic mechanism of MS related to energy failure and associated MRI imaging techniques were reviewed.

10.Associations of HLA-DQA1 and -DQB1 alleles with systemic sclerosis in Zhuang and Han nationalities in Guangxi Zhuang Autonomous Region
Chinese Journal of Dermatology 2011;44(4):235-237
Objective To explore the potential associations of HLA-DQA1 and DQB1 alleles with systemic scleroderma (SSc) in Zhuang and Han nationalities in Guangxi Zhuang Autonomous Region. Methods Genomic DNA was extracted from the peripheral blood of SSc patients of Zhuang (n=50) and Han (n=50) nationality,normal controls of Zhuang (n=100) and Han (n=100) nationality in Guangxi Zhuang Autonomous Region.PCR with sequence-specific primers (PCR-SSP) was used to detect HLA-DQA1 and -DQB1 alleles in these subjects. Results There was a significant increase in the frequency of HLA-DQA1*0401, -DQBl*0501 and -DQB1*0601 alleles in the patients of Zhuang nationalty(RR=4.056,χ2=15.407,PC=0.001;RR=4.472,χ2=10.653,Pc=0.004;RR=3.473,χ2=10.06,Pc=0.008)compared with normal controls of Zhuang nationality,and in the frequency of HLA-DQA1*0401,DQA1*0601 and DQB1*0601 alhles in patients of Han nationality (RR=9.333,χ2=8.371,Pc=0.036;RR=8.071,χ2=20.130,Pc=0.000;RR=3.764,χ2=10.755,Pc=0.004)compared with normal control of Han nationality.However,the frequency of HLA-DQA1*0201 allele was statistically lower in the patients of Zhuang and Han nationality than in the controls of corresponding nafionality (χ2=13.583,Pc=0.002;χ2=12.209,Pc=0.004).Conclusions HLA-DQA1*0401 and-DQB1*0601may be susceptible genes for SSc in Zhuang and Han nationalities,HLA-DQB1*0501 for Sse in Zhuang nationality,and HLA-DQAl*060l for SSc in Han nationality in Guangxi Zhuang Autonomous Region.
