Microscopic identification and NIRS methods were applied to identify Clematidis Radix et Rhizoma of two different origins. The results showed that both methods could identify the samples. NIRS could identify the two samples nondestructively, and provides a basis for establishment of a standard herbs radix clematidis NIRS fingerprint in the future.

Abstract: Objective　To analyze the laboratory indexes of patients infected with malaria patients and COVID-19, so as to provide reliable evidence for the diagnosis of mixed infection of both. Methods　The routine clinical laboratory items such as routine blood, biochemistry and lymphocyte subsets were tested in three cases of COVID-19 complicated with falciparum malaria who admitted to Guangzhou Eighth People's Hospital Affiliated to Guangzhou Medical University from July to December 2020 were tested. Laboratory data were stage-wise analyzed in conjunction with changes in the course of disease. Results　Three patients confirmed COVID-19 infection recruited all had malaria infection history. Fever, headache, and other symptoms emerged on the 4rd to 11th day after admission. Malaria parasite was detected by malaria parasite antigen testing and blood smear testing, and all three patients had re-ignition of malaria after being confirmed COVID-19 infection. In the early stage of malaria relapse, lymphocytes decreased, CRP and SAA increased, and gradually returned to normal level after antimalarial treatment. Interestingly, we only found one patient at the initial stage of malaria detection showed PLT decreased, no other unnormal changes in other routine blood results (WBC, ESO) and liver function results (ALT, AST, GGT, TBIL, DBIL, CG) were found from the beginning to end course of the disease. Conclusion　COVID-19 infection may promote the resurgence of malaria, so the relapse of malaria should be monitored especially for the patient with malaria infection history who begin to develop fever and other symptoms a few days after the diagnosis of COVID-19. The inflammatory indicators would be worth able as an auxiliary judgment basis for the effective treatment of the two combined infection.

This paper introduced a composite method of treating gastrointestinal tract cancer-thermo-chemotherapy.A complete set of intelligentialized real-time measure and control system was well designed. The experiment result showed that this system has a stable performance and good real-time.

Objective To discuss the psychology and behavior of elderly hypoglycemia patients with symptomatic carotid artery stenosis, and compare the differences in psychology and behavior between groups.Methods Measurement and assessment with fall efficacy scale on psychology towards prevention of fall among 408 elderly hypoglycemia patients (＞ 60 years old) with symptomatic carotid artery stenosis were taken; They were divided for hypoglycemia history, carotid artery stenosis and ischemia sympton, and fall history; SPSS 17.0software was applied to do statistical analysis. Results There is significant difference on fall efficacy scale score between groups with and without hypoglycemia, carotid artery stenosis and ischemia sympton, and fall history (P ＜0. 0 1). Conclusions Subdividing symptomatic groups, applying preventive intervention procedure on prevention of fall, education on psychology and behavior towards prevention of fall are the effective psychological intervention measures on prevention of fall.

Objective To test and compare the color and translucency between the mono-component light-cure adhesive resin and try-in paste with same number for porcelain veneer restorations, and evaluate the consistency of the materials. Methods Variolink Veneer and Relyx Veneer were involved in the study.The adhesive resins and try-in pastes were added into a model of diameter of 10 mm and thick of 2 mm with white background and covered with filtered cover glass, and then the resins was cured with light. The color ( L* , a* , b* ) of these samples was test and △E was also calculated to evaluate the color consistency of samples. The resins and try-in pastes were made into a thin layer of 0. 15 mm, and their translucency was tested under the light from 380 μm to 780 μm. Average translucency was calculated. Tukey t-test for multiple comparisons was used to analysis the differences of △E. Paired t-test was used to analysis the differences of translucency of them. Results Tukey's t-test shows that the evaluation of AE of TR ( 1.11 ±0. 18) was a; those of LV-1 (6. 38 ±0. 45), LV-2(5.94 ±0. 19), A1 (7. 54 ±0. 20), WO(4. 24 ± 1.14)were b; those of HV +2(10. 90 ±0. 41), HV +1(11.48 ±0. 17), LV-3( 10. 69 ±0. 13), B0. 5( 13.26 ±0. 21 ) were c; and those of HV +3(21.94 ±0. 21 ), MV0(29. 78 ±0. 14), A3(32. 67 ±0. 19) were d(a,b, c, d meaned that the consistency of resin and try-in paste became lower and lower). There were significant differences between resin and tray-in paste in 7 colors(A1, TR, HV +3, HV +2, HV +1, LV-2, LV-3) of 12 colors(P ＜ 0. 01 ). Conclusions The consistency of color and translucency between most adhesive resin and try-in paste with same number is low. This kind of materials should be used with caution in demanding cases.

Lie detection technology has been applied increasingly to investigate and solve criminal cases. This article explores the evolvement of lie detection technology in the ancient times and the application of the psychological and physiological parameters which have become more accurate with the introduction of modern polygraph. The cognitive exploration and the application of Event Related Potentials (ERPs), functional Magnetic Resonance Imaging (fMRI), and Event-Related functional Magnetic Resonance Imaging (E-R fMRI) have made detection technology focus on the brain activities, which produce more objective results by tracing the original state of lying. In summary, this article describes different types of lie detections, simple and complex, their working principles, the latest development, and the prospect of their application in forensic science.

Objective To investigate the relationship between matrix metalloproteinase(MMP)1 gene-519A/G polymorphism and the risk of coronary heart disease(CHD)in Northern Chinese Han population.Methods A total of 517 patients with CHD and 380 healthy adults diagnosed by coronary angiography were genotyped by polymerase chain reaction-restriction fragment length polymorphism and DNA sequence technology for the-519A/G polymorphism in MMP1 gene.Results (1)The frequency of AA genotype was significantly higher in patients with CHD than that in controls[67.70%(350/517) vs.40.26%(153/380),OR=1.64,P＜0.001,95%CI:1.44-1.86].People carrying A allele had increased risk for CHD(OR=1.49,P＜0.001,95% CI:1.33-1.69).(2)The frequency of AA genotype was higher in patients with acute coronary syndrome(ACS)than patients with stable angina pectoris[68.81%(278/404)vs.51.76%(44/85,),P＜0.01,95% CI:1.04-1.27].The A allele carriers were more likely to develop ACS(OR=1.11,95% CI:1.01-1.21,P＜0.05).Conclusion Our data shows MMP1 gene -519A/G polymorphism is associated with the risk of CHD,and A allele carriers are more susceptible for CHD in Northern Chinese Han population.
