Wuhan University built up a new modular integrated curriculum in clinical medicine oriented for post competence,by learning from the successful international experience and the course of vertical and horizontal integration.The curriculum focused on five modules (including humanities and vocational course,courses of integrated medicine,clinical practice and thinking,innovation awareness and ability,prevention and health promotion program) and the eight integrated curriculum (including human structure,organization and function,cell,molecule and gene,reaction,nerve injury science,pathogen biology,CPPT,clinical skills).During the curriculum implementation,Wuhan University vigorously promoted the group discussion teaching,cultivated high-quality core teaching team,and effectively carried out curriculum construction and teaching evaluation,which effectively improved the level and quality of medical personnel training.

Objective: Using the COI Barcode to establish the standard method to identify the traditional Chinese medicine of deer products. Methods: In this study, DNA extraction, PCR amplification, and sequencing of experimen-tal samples (deer antler, penis and testis, tendon, tail, bone, foetus) were successful. COI sequence database were constructed and commercial crude drugs of deer were investigated and analyzed. Results: By using universal COI primer,PCR amplification is preferably. All the species could be identified based on COI sequences database of tra-ditional Chinese medicine of deer which contained 101 samples of 8 species. We have collected 40 commercial crude drugs in which 18 samples were identified as species described in Chinese pharmacopoeia. Conclusion: DNA barcode technology based on COI sequence could be a standard approach to identify traditional Chinese medicine of deer products, and provide the basis for the identification of commercial deer medicine.

Objective To investigate the clinical value of coronary artery Z-scores on echocardiography in diagnosing coronary artery abnormalities. Methods The echocardiography results of 612 patients with Kawasaki disease (KD) at the acute and recovery phase were retrospectively studied. Coronary artery luminal diameters were converted to body-surface-area-adjusted Z-scores. According to coronary Z-scores classiifcation, all the subjects were divided to four groups:415 cases with no dilation (ND), 133 cases with small coronary artery abnormalities (SCAAs), 47 cases with large coronary artery abnormalities (LCAAs), and 17 cases with giant coronary artery abnormalities (GCAAs). Clinical features (gender, age, typical clinical manifestations, fever duration) and laboratory results (CRP, ESR, WBC, PLT) were compared among all the four groups. Coronary artery diameters and the Z-scores were compared between acute and convalescence phase. Results Along with the increase of coronary Z-score, fever duration was prolonged [ND group:(7.75±3.12) d, SCAAs group (8.50±4.12) d, LCAAs group: (8.57±3.58) d, GCAAs group: (11.88±4.33) d, F=22.375, P<0.05]. With coronary Z-score increasing, PLT also increased (F=22.029, P=0.000), and the highest PLT was observed in GCAAs group. There were no significant differences in the CRP, ESR and WBC among all the four groups (F=0.236, 1.116, 0.121, all P>0.05). No significant different coronary diameters were found in ND cases between recovery and acute phase [(2.24±0.34) mm vs (2.33±0.36) mm, t=1.926, P > 0.05]. But there were significant difference in the coronary Z-scores of ND patients between recovery and acute phase (0.41±0.82 vs 1.17±0.75, t=8.332, P < 0.05). The coronary Z-scores in SCAAs group (1.32±0.89 vs 3.40±0.62, t=11.073, P < 0.05), LCAAs group (3.12±2.27 vs 6.20±1.28, t=4.579, P<0.05) and GCAAs group (11.88±6.77 vs 20.4±9.70, t=3.480, P<0.05) at recovery phase were smaller than values at acute phase. Conclusions The KD coronary Z-scores are the body-surface-area-adjusted standard value, and not subject to the influence of children growth and development. Therefore, it may accurately evaluate the severity of coronary artery abnormalities and its recovery process. Accurate quantitative of the coronary artery luminal dimensions is important in KD clinical management and prognosis prediction.

Objectives: To investigate the expression of phosphoserine aminotransferase 1 (PSAT1) in pancreatic cancer tissues, and its potential role in pancreatic cancer. Methods: The expression of PSAT1 in 98 human pancreatic cancer tissues, which were collected from the People＇s Hospital of Guizhou, between July 2013 to July 2017, and the corresponding adjacent normal tissues was analyzed by immunohistochemical staining. Additionally, the relationship between the expression of PSAT1 and the clinicopathological parame-ters, overall survival (OS), and disease-free survival (DFS) of patients with pancreatic cancer was evaluated. The human pancreatic can-cer cell lines, BxPC-3 and SW1990, were transfected with PSAT1-siRNA, to investigate the effect of PSAT1 knockdown on cell prolifera-tion, migration, and invasion. Additionally, we performed Western blot to assess the expression of PI3K/Akt/mTOR-related proteins in PSAT1-knockdown cells. Results: The percentages of PSAT1-positive cells in pancreatic cancer and adjacent non-tumor tissues were 69.4% (68/98) and 5.0% (5/98), respectively, indicating a significantly higher expression of PSAT1 in pancreatic cancer tissues com-pared to adjacent non-tumor tissues (P<0.05). The increased expression of PSAT1 in pancreatic cancer tissues correlated with lymph node metastasis and TNM stage. Kaplan-Meier analysis suggested that a high expression of PSAT1 correlated with a poor OS and DFS compared to a low expression of PSAT1 (P<0.05). Cox regression analysis showed that the expression of PSAT1 is an independent prog-nostic marker for OS and DFS in pancreatic cancer patients (P<0.05, all). Transient transfection of BxPC-3 and SW1990 cells with PSAT1-siRNA markedly reduced the cell proliferation, migration, and invasion abilities of these cells compared to transfection with NC-siRNA (P<0.05). Knockdown of PSAT1 in pancreatic cancer cells also inhibited the expression of p-Akt and p-mTOR (P<0.05). Conclusions: The expression of PSAT1 increases in human pancreatic cancer tissues and cell lines. Additionally, PSAT1 regulates cell proliferation and in-vasion through the PI3K/Akt/mTOR pathway.

ObjectiveTo screen out the mRNAs involved in the resistance of hepatoma cells to anlotinib using ceRNA microarray. MethodsHigh-dose shock combined with low-dose induction was used to culture hepatoma cells resistant to anlotinib, and CCK8 assay was used to verify the difference in the proliferation of drug-resistant hepatoma cells treated by anlotinib. The ceRNA microarray was used to screen out the differentially expressed genes between drug-resistant hepatoma cells and normal hepatoma cells, and real-time PCR was used to verify the differentially expressed genes detected by some microarrays. the independent samples t-test was used for comparison of continuous data between two groups, and the Kaplan-Meier method was used to analyze the overall survival of hepatoma cells samples, and the log-rank test was used to compare survival rates. Fisher’s exact test was used for chip screening. ResultsThere was a significant difference in gene expression between drug-resistant hepatoma cells and normal hepatoma cells, and 10 genes with the greatest difference were screened out for analysis by reducing the range. There were 4 genes associated with drug resistance and tumor growth, i.e., BIRC2, BIRC7, ABCC2, and MAPK8. There were significant reductions in the expression levels of BIRC2, ABCC2, and MAPK8 (P=0001 4, 0001 2, and 0.011 8), and there was a significant increase in the expression of BIRC7 (P＜0.001). The results of real-time PCR were consistent with those of microarray (t=10.74,32.65,18.34, and 2.80; P=0.000 4, 0.000 1, 0.000 1, and 0.044 8). The high expression of BIRC7 and the low expression of MAPK8 were associated with the significant reduction in survival time (P=0.022 0 and 0.005 6). ConclusionBIRC2, BIRC7, ABCC2, and MAPK8 are differentially expressed between anlotinib-resistant hepatoma cells and normal hepatoma cells and may be involved in the resistance of hepatoma cells to anlotinib.
