Tianjin Medical Journal 2016;44(3):373-376
Objective To investigate the symptoms of diarrhea and the behavior of medical treatment after diarrhea in 2013 in Tianjin City, and provid background information for the future population monitoring. Methods A stratified sam?pling method was used to investigate the symptoms, medical treatment and self medication behavior of 4028 residents in Tianjin. Results The number of people who had diarrhea in 2013 was 324, and the incidence rate of diarrhea was 8.04%. Diarrhea was mainly occurred in May-October (n=241, 74.38%). The incidence of diarrhea was the highest in 60-74 years old group, followed by 75-years old and 0-14 years old groups. The incidence of diarrhea was the lowest in 15-29 years old grouop. A total of 121 patients with diarrhea chose to go to hospital (47.08%), 78 patients chose to buy medicine for treat?ment (30.35%) and 58 patients did not do any disposal (22.57%). Among the patients with diarrhea, the highest proportion of patients chose to go to the first grade and the following medical institutions (68.59%, 83/121). There were 14.05%(17/121) and 17.36%(21/121) patients chose to go to the second and the third levels of medical institutions for the treatment. The av?erage cost for patients with diarrhea was 60 (20, 200) yuan. The purchasing expenditure median was 20 (11,50) yuan. The medical spending was more than the purchase of medicines (Z=2.412, P<0.05). The average cost of medical treatment was more higher in the second and the third levels of medical institutions than that of the first medical institution ( Z=50.709,P<0.05). The average cost of medical treatment was in turn increased for patients with diarrhea treated in Baodi county, Xiqing county, Hangu county and Heping county (Z=74.282,P<0.05). There was no statistical significance in medical expenses be?tween patients with different ages and patient with or without medical insurance. Conclusion There are high incidence of diarrhea in patients under 15 years old and patients over 60 years old. Residents suffering from diarrhea mainly choose their own medicine and the treatment in the first and following medical institutions.

Chinese Journal of Interventional Cardiology 2014;(8):515-519
Objective To study the changes in and correlations between the partial pressure of end-tidal carbon dioxide (PETCO2) and the coronary perfusion pressure during cardio-pulmonary resuscitation (CPR) based on the cardiac arrest dog models of ventricular fibrillation by electric shock. Methods 36 healthy dogs were evenly randomized into 3 groups including 4 minutes close-chest CPR(CCCPR) group, 4 minutes open-chest CPR(OCCPR) group, and 8 minutes OCCPR group. There were 12 dogs in each group, half male and half female. In the process of CPR, all parameters about PETCO2 and CPP were recorded. Results In the 4 minutes CCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.992 (P<0.05), which was in positive linear correlation. In the 4 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.937 (P < 0.05), which also showed positive linear correlation. In the 8 minutes OCCPR group, the correlation coefficient between the CPP and the PETCO2 was 0.952 (P<0.05), and was also in positive linear correlation. The percentage of ROSC was 66.7(8/12) in the 4 minutes CCOPR group, 100%(12/12) in the 4 minutes OCCPR group and 58.3%(7/12) in the 8 minutes OCCPR group. There were statistical differences in CPP, PETCO2 between models with ROSC and without ROSC at 1, 2, 5, 10, 15 and 20 mins of CPR (all P<0.05). Conclusions This research shows that there is a close positive linear relationship between the coronary perfusion pressure and the PETCO2, and PETCO2 could be used to evaluate the prognosis of the CPR.
8.Expression of vascular endothelial growth factor in the treatment of diabetic foot using bone marrow mesenchymal stem cell transplantation
Chinese Journal of Tissue Engineering Research 2013;(40):7169-7174
BACKGROUND:Bone marrow mesenchymal stem celltransplantation has been confirmed to have excellent effect on the treatment of diabetic foot.
OBJECTIVE:To assess the therapeutic effect of bone marrow mesenchymal stem celltransplantation on diabetic foot ulcers and the expression of vascular endothelial growth factor.
METHODS:Literatures concerning the effect of bone marrow mesenchymal stem celltransplantation on foot diabetic and expression of vascular endothelial stem cells were retrieved. Articles that met the criteria were analyzed in depth. Here, we analyzed the experimental research and clinical application of bone marrow mesenchymal stem cells in the treatment of diabetic foot. In experimental studies, rat models of diabetic foot ulcers were established and subjected to bone marrow mesenchymal stem celltransplantation to observe wound healing of ulcers and analyze the expression of vascular endothelial growth factor. In clinical research, the fol ow-up was conducted in diabetic foot patients undergoing bone marrow mesenchymal stem celltransplantation to observe the wound healing of ulcers and adverse reactions.
RESULTS AND CONCLUSION: Experimental studies have shown that bone marrow mesenchymal stem celltransplantation is better than conventional treatment in the treatment of diabetic foot ulcers, but the healing of diabetic foot ulcers is stil slower than that of normal ulcers. After celltransplantation, the expression of vascular endothelial stem cells is elevated but stil lower than that in the normal ulcer controls. Clinical studies have shown that for patients with diabetic foot ulcers, the ulcer wound can be healed after bone marrow mesenchymal stem celltransplantation, as wel as there are no cardiovascular and cerebrovascular diseases, liver and kidney damage and changes in bleeding and coagulation time.
