For a long time, the cultivation of medical students’ scientific research and innovation abilitymainly depends on scattered extracurricular scientific research activities. With limited students, unsystematic teaching and inadequate administrative guarantee, it often results in obvious weakness andinefficiency. Since 2002, the Biochemistry and Molecular Biology teaching team in Shantou UniversityMedical College has been working on a “3+X” model to nurture the scientific research and innovationability of medical students. Guided by the concepts of complementary development of science andeducation, student-centeredness, and Problem-based Learning, a model is established based on the‘HEART” professionalism courses and the academy culture specific to Shantou University. We also takefull advantage of the first-tier disciplines of biology, basic medicine and clinical medicine in ShantouUniversity and collaborate with other professional teaching teams. It is conceptualized in a framework thatembraces the comprehensive connotation of scientific research and innovation ability and adopts a corecurriculum system that runs through the 5-year medical undergraduate education. In this model, " 3" means " whole-person training", " whole-process training" and " omni-directional training" for medicalstudents; " X" refers to several confirmatory dimensions of the operational effectiveness of the " 3+X" model, including organizing medical students to participate in various forms of national college students’ innovative experimental research competitions, international college students’ academic seminars, writingand publishing academic papers by medical undergraduates as the first author, etc. The model proves tobe effective in cultivating the scientific research and innovation ability of medical students, hence settinga good example to solve the current problems in the cultivation of medical students’ scientific researchand innovation ability.

Lancang Lahu autonomous county, where the Lancang-Mekong River flows by, was selected as the case site to investigate the traditional medicinal knowledge(TMK). A comparison of TMK between Lancang county and other places in the Lancang-Mekong sub-region was conducted. Research on TMK has been seldom reported although there are abundant medicinal resources in this sub-region. The key informant interview and other methods have been adopted in the field surveys in the past six years. The investigation revealed that there was rich TMK and various herbal medicine resources in Lancang county. A total of 220 folk prescriptions have been collected, which were normally simple with easy processing methods and usages, and most raw materials were freshly used. As for medicinal plants, 121 species in 67 families have been documented. Other findings included that TMK in Lancang county was remained at the level of medication based on experience only. The processing methods of herbal medicines were simple and the bioactive ingredients were not clear. Without text and cultural support for self-teaching, coupled with conservative inheritance, it resulted in massive losses of TMK. The folk doctors have accumulated their factions based on self-study or ancestral experience. There was different treatment experience among folk doctors, but the safety and effectiveness should be paid attention to. The folk doctors used various herbal medicines, but there was a lack of standards or specifications for quality control. Given the problems existing in inheritance and development, conservation strategies were proposed in the present study.

@#【Objective】To explore the feasibility and simplicity of intelligent automatic registration ultrasound-CT/ MR fusion imaging based on liver surface in localization of focal liver lesions. 【Methods】 Thirty patients with detected focal liver lesions by contrast- enhanced CT or MR were enrolled for ultrasound- CT/MR fusion imaging using the PercuNav fusion imaging system in PHILPS EPIQ7. Both intelligent automatic registration ultrasound- CT/MR fusion imaging based on liver surface(intelligent method)and the conventional internal plane method(manual method)were used for ultrasound-CT/MR fusion imaging. The success rate of registration,the initial registration error and the times of fine-tuning were compared between these two methods.【Results】In all 30 patients,the success rates of registration were both 96.67%(29/30)using intelligent method and manual method. There was no significant difference between these two methods when compared the initial registration error and the times of fine- tuning (P>0.05). According to the further stratified analysis,in 10 lesions in the left liver,the initial registration error of the manual method was less than that of intelligent method,the difference was statistically significant(P=0.00). Although the times of fine-tuning of the manual method was less than that of intelligent method,there was no statistically significant difference(P=0.09);In 20 lesions in the right liver,the initial registration error and the times of fine-tuning of the intelligent method were superior to those of the manual method. The differences were statistically significant (P<0.05). 【Conclusion】 Intelligent automatic registration ultrasound- CT/MR fusion imaging based on liver surface is a feasible method with high success rate for ultrasound-CT/MR fusion imaging. Compared with the conventional internal plane method,the fusion imaging process is more simple and efficient for the lesions in right liver. It helps to reduce experience dependence of fusion imaging for the operators.

Objective@#To investigate the association between the whole blood riboflavin level and the occurrence, development and prognosis of esophageal squamous cell carcinoma (ESCC) in China. @*Methods@#From March 2014 to September 2018, ESCC patients from three hospitals (the Affiliated Hospital of Medical College of Shantou University, Shantou Central Hospital in Southern Chaoshan area and First Affiliated Hospital of Zhengzhou University in Northern Taihang Mountain) were selected as a case group; non-esophageal patients who had a physical examination were selected as a control group. The case and control group were paired by age (±5 years) and a 1:1 ration. A total of 1 528 subjects were enrolled including 764 patients in the case group and 764 patients in the control group. About 3-5 ml venous blood samples were collected, and the erythrocyte glutathione reductase activity coefficient (GRAC) was measured to assess the whole blood riboflavin level. A multivariate conditional logistic regression model was used to analyze the association between the GRAC and the risk of ESCC. The association between the GRAC and the prognosis of ESCC was analyzed by using Cox proportional risk regression model based on 288 patients with complete survival data. They were divided into two groups, the high GRAC group (GRAC≥7.87) group and the low GRAC group (GRAC<7.87) according to the strongest correlation between the total survival time, survival outcome and GRAC (GRAC=7.87). @*Results@#Among the 1 528 patients, 958 patients were from Southern Chaoshan area, including 479 patients in the case group with an average age about (59.90±9.34) years and 479 patients in the control group with an average age about (59.55±8.77) years. Other 570 patients were from Northern Taihang Mountain area, including 285 patients in the case group with an average age (58.39±5.19) years and 285 patients in the control group with an average age about (58.74±4.57) years. The multivariate conditional logistic regression showed that the OR (95%CI) of the GRAC and the risk of ESCC was 1.009 (0.998-1.019). The Cox proportional hazard regression model analysis showed that the HR (95%CI) of the high GRAC group was 1.712 (1.034-2.824) compared with the low GRAC group in the 50-70 years group. @*Conclusion@#The whole blood riboflavin level might not be associated with the occurrence of ESCC. The high whole blood riboflavin level would be more beneficial to the prognosis of ESCC patients aged 50-70 years.

AIM:To investigate the role of autophagy in inhibition of human lung cancer PC 9 cell proliferation by ursolic acid(UA)as well as the underlying mechanism.METHODS:MTT assay and Trypan blue exclusion test were performed to analyze the effect of UA on the proliferation of PC 9 cells.The PC9 cells were treated with UA,and autophagy was observed under fluorescence microscope through acridine orange staining.The expression of autophagy-associated pro-teins LC3 and ATG5 in the PC9 cells were detected by Western blot.The effect of UA,3-methyladenine(3-MA)3-MA or their combination on the cell viability was measured by MTT assay.RESULTS:The viability of PC9 cells was significantly inhibited by UA(P<0.05 or P<0.01).The number of bright red fluorescence positive cells was significantly increased after treatment with UA.The protein expression of LC3-II and ATG5 was significantly up-regulated compared with control group(P<0.01).Furthermore,combination of UA and 3-MA resulted in a substantial decrease in cell viability compared with using UA alone(P<0.01).CONCLUSION: UA inhibits the proliferation and induces the autophagy of the PC 9 cells,in which autophagy plays a protective role.The inhibition of autophagy significantly promotes the death of the PC 9 cells induced by UA.
摘要
Hypericum stellatum is an important ethnomedicinal plant endemic to southwest China. Ultra high performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was applied to analyze the chemical constituents of H. stellatum. Seventeen compounds from H. stellatum were tentatively identified using UPLC-Q-TOF-MS data. Antioxidant activity and total phenolic content were investigated by DPPH assay and Folin-Ciocalted methods. The EtOAc extract with high total phenolic content showed prominent antioxidant activity. The EtOAc extract of H. stellatum was separated and purified by column chromatography, including silica gel, Sephedex LH-20, and RP-HPLC. The isolates were defined by 1D, 2D NMR data. As a result, ten compounds were isolated and assigned as quercetin (Ⅰ), quercetin 3---D-glucopyranoside (Ⅱ), 1,3,6,7-tetrahydroxylxanthone (Ⅲ), 1,3,5,6-tetrahydroxyxanthone (Ⅳ), 1,3,7-trihydroxyxanthone (Ⅴ), 3, 6, 7-trihydroxy-1-methoxyxanthone (Ⅵ), calycinoxanthon D (Ⅶ), caffeic acid ethyl ester (Ⅷ), chlorogenic acid (Ⅸ) and chlorogenic acid ethyl ester (Ⅹ). This is the first report on chemical constituents and bioactivity of H. stellatum. The antioxidant activity of chemical constituents was tentatively found, which provided a foundation for further researches on the genus Hypericum and the traditional uses of H. stellatum.

Acorus macrospadiceus is a common medicinal and food plant used different ethnic groups in Guizhou and surrounding areas. In this paper, the leaf and rhizome tissues of A. macrospadiceus were hydro-distilled to extract the volatile oils. The chemical constituents of these oils were analyzed by GC-MS and identified using the NIST 14.0 & NIST 14.0s mass spectral libraries. The relative contents of chemical constituents from the different plant parts were determined by area normalization. The analysis of A. macrospadiceus volatile oils resulted in the identification of 25 compounds from the leaf and 36 compounds from the rhizome. The identified compounds accounted for 97.85% of the leaf essential oil content and 97.18% of the rhizome essential oil content. The main volatile constituent of A. macrospadiceus was identified as estragole (93.56% of total oil content in leaf and 71.62% of total oil content in rhizome). Fourteen compounds were found to be common to essential oils of both leaf and rhizome. However, the relative amounts of these compounds were significantly different between the plant parts; the remaining identified compounds were unique to each part. This comparison of volatile oils from the different parts of A. macrospadiceus can serve as a reference for future development. Because of the higher estragole content and better harvesting sustainability of the leaves compared to rhizomes, the leaves of A. macrospadiceus deserve consideration for sustainable development. However, when we use it as a medical plant, we should draw a distinction between it with A. tatarinowii.

Objective To investigate the therapeutic effect of argon-helium cryoablation combined with transcatheter arterial chemoembolization (TACE) for primary hepatocellular carcinoma (HCC) and its influence on vascular endothelial growth factor (VEGF) level, and to compare it with simple TACE treatment. Methods During the period from Aug. 2013 to Aug. 2014 a total of 50 patients with primary HCC were admitted to Hunan Provincial People’s Hospital. The patients were randomly and equally divided into group A (TACE group, n=25) and group B (argon-helium cryoablation+TACE group, n=25). VEGF levels in the peripheral blood were determined before and after the treatment, and the results were statistically compared between the two groups. Results After the treatment the VEGF level in group A was significantly increased when compared with preoperative VEGF level (P<0.05). In group B, the VEGF level was decreased after the treatment, which was statistically significant lower than the preoperative VEGF level (P<0.05). The differences in VEGF level between the two groups were statistically significant (P<0.05). Conclusion The statistic analysis of VEGF levels indicates that argon-helium cryoablation combined with TACE is probably superior to simple TACE in the inhibition of tumor angiogenesis.
