Abstract
Abstract Objective To discuss the application value of CT scanning technology in cause of death determination of medical dispute cases. Methods From July 2017 to December 2018, postmortem CT imaging data of 12 medical dispute cases were collected. CT imaging diagnosis results and anatomy findings as well as differences between antemortem and postmortem CT diagnosis were compared. The advantages and disadvantages of CT routine tests of the cadavers in terms of the diagnosis of disease and damage were analyzed. Results The comparison between CT imaging diagnosis and anatomical findings showed that CT scans had advantages in the diagnosis of disease and damage with large differences in density changes, such as atelectasis, pneumonia, calcification, fracture and hemorrhage, etc. The comparison of CT diagnosis in antemortem and postmortem examination showed that the cadavers of medical dispute cases were well preserved and that postmortem CT scan was meaningful for the diagnosis of antemortem diseases. Conclusion Virtual anatomy technology has a relatively high application value in postmortem examination of medical dispute cases. It can provide effective information for the appraisers before the autopsy and can also provide a reference for cause of death analysis when the anatomy cannot be performed.

Abstract
Abstract Objective To investigate the sequential changes of the number of neutrophils and myofibroblasts during diabetic wound healing, and discuss its application value in wound age estimation. Methods Diabetic DB mice and mice of the same age in the normal control group were selected, a wound healing model was established, wound samples were taken at different time points, while the number of neutrophils and myofibroblasts during diabetic wound healing were determined by immunohistochemical staining technique. Results The number of infiltrated neutrophils in the wounds of control and diabetic groups reached the peak respectively at 12 h and 5 d after injury. Compared with the control group, the number of neutrophils in the diabetic group decreased significantly from 6 h to 1 d after injury, but increased markedly from 5 d to 14 d. From 5 d to 10 d after injury, the average number of neutrophils at high magnification in wounds of the diabetic group was over 30, while that of neutrophils in wounds of the control group was less than 20. Myofibroblasts appeared in wounds from 3 d to 14 d after injury in the control group and from 5 d to 14 d after injury in the diabetic group. The difference in the number of myofibroblasts in wounds between control group and diabetic group from 3 to 7 d after injury had statistical significance. Conclusion In comparison with normal wound healing, the number of neutrophils and myofibroblasts during diabetic wound healing shows different sequential changes. The results of this study can provide reference for wound age estimation of patients with severe diabetes.

Abstract
Our aim was to investigate the role of chemokines in promoting instability of
coronary atherosclerotic plaques and the underlying molecular mechanism. Coronary
angiography and intravascular ultrasound (IVUS) were performed in 60 stable angina
pectoris (SAP) patients and 60 unstable angina pectoris (UAP) patients. The
chemotactic activity of monocytes in the 2 groups of patients was examined in
Transwell chambers. High-sensitivity C-reactive protein (hs-CRP), monocyte
chemoattractant protein-1 (MCP-1), regulated on activation in normal T-cell expressed
and secreted (RANTES), and fractalkine in serum were examined with ELISA kits, and
expression of MCP-1, RANTES, and fractalkine mRNA was examined with real-time PCR. In
the SAP group, 92 plaques were detected with IVUS. In the UAP group, 96 plaques were
detected with IVUS. The plaques in the UAP group were mainly lipid 51.04% (49/96) and
the plaques in the SAP group were mainly fibrous 52.17% (48/92). Compared with the
SAP group, the plaque burden and vascular remodeling index in the UAP group were
significantly greater than in the SAP group (P<0.01). Chemotactic activity and the
number of mobile monocytes in the UAP group were significantly greater than in the
SAP group (P<0.01). Concentrations of hs-CRP, MCP-1, RANTES, and fractalkine in
the serum of the UAP group were significantly higher than in the serum of the SAP
group (P<0.05 or P<0.01), and expression of MCP-1, RANTES, and fractalkine mRNA
was significantly higher than in the SAP group (P<0.05). MCP-1, RANTES, and
fractalkine probably promote instability of coronary atherosclerotic plaque.

Abstract
BACKGROUND The prevalence of asthma has increased in recent years. Epidemiological studies suggest a correlation between the onset of asthma and dietary nonallergic factors especially high calorie diet. These can be regarded as other potentially important risk factors. OBJECTIVES To observe the effect of dietary calorie reduction on chronic asthma in adults or children. SEARCH STRATEGY We searched the Cochrane Airways Group trials register using prespecified terms. We assessed bibliographies from included studies, and contacted authors of known studies for additional information about published and unpublished trials. Date of most recent search: May 2004 SELECTION CRITERIA Randomised-controlled trials of dietary calorie reduction were included. DATA COLLECTION AND ANALYSIS Three authors assessed each study independently. Disagreement was resolved by consensus. Quality assessment was performed independently. MAIN RESULTS One trial of fair methodological quality with a total of 38 patients suffering from chronic asthma was included. There were significant increases in FEV(1) and FVC in the active treatment group compared with control. No data pertaining serious adverse effects were reported from the interventions. AUTHORS' CONCLUSIONS There is currently a very small amount of evidence assessing the effects of dietary interventions intended as part of a wide-ranging weight-loss programme. Whilst we are unable to recommend these strategies as concomitant interventions with drug-based therapy for the specific management of asthma, dietary interventions such as weight-loss programmes may provide benefits in specific patients. However, the impact of a calorie-controlled diet on the signs and symptoms of asthma in the general asthmatic population is yet to be established.

Abstract
With suspension cultured cells of tobacco (Nicoliana Tobacum L.), effects of inorganic phosphate, nitrogen sources and carbon source on cell growth and CoQ10 content were investigated. It showed that, When treated with 30 g/L of sucrose, the total amount of CoQ10 was highest (8212 g/L); and the cell biomass and CoQ10 content were 19.8 micrograms/L, 414.7 micrograms/g(dwt) respectively. When treated 340 mg/L of KH2PO4, the cell biomass, the content and total amount of CoQ10 were 21.04 g/L, 514.5 micrograms/g(dwt) and 10824 micrograms/L respectively. When treated with the ratio of NH4+/NO3- was 1:2, the cell biomass, the content and total amount of CoQ10 were 21.04 g/L, 514.3 micrograms/g(dwt) and 10,820 micrograms/L respectively. The high ration of NH4+/NO3- was suitable for the formation of CoQ10, but not for the cell growth.

Abstract
Compound salviae miltiorrhizae injection was administered after operation for 28 cases of severe pancreatitis, and 13 cases were taken as a control group. The results showed that: (1) the difference was not obvious in the morbidity of complications between the two groups, but the mortality (3.6%) of the trial group was significantly lower than that (30.8%) of the control group (P < 0.05); (2) Hematocrit was clearly decreased from 46.1 +/- 5.2% to 33.2 +/- 3.9% in the trial one (P < 0.05), but platelet and hemoglobin showed no statistical significance. It is concluded that compound salviae miltiorrhiza injection might improve hemorheologic abnormalities of the disease, promote the recovery of the pancreatic tissue, and correct the serious complications such as adult respiratory distress syndrome etc.
