Objective To analyze the differential gene expression profiling of liver in rats subjected to hemorrhagic shock(HS) and sham hemorrhage shock(SHAM) by gene chip technology, thus to evaluate the possible molecular pathogenesis of HS. Method 20 male Wistar rats were randomly divided into a SHAM group and a HS group, with 10 rats in each group. Hepatic gene expression profiles were detected by oligonucleotide microarrays of 5705 mouse genes in two groups for three times. Genes with ratio(R) > 2 were identified as up-regulated and R < 0.5 were identified as down-regulated. Biological function of differentially expressed genes was analyzed and 9 genes were selected to undergo semi-quantitative RT-PCR. Results Among the total 5705 probes detected,86 genes showed differential expression in HS group comparison with SHAM group. The expression levels of 72 genes were up-regulated while those of 14 genes were down-regulated significantly. Differentially expressed genes were classified according to their biological function: transport genes, transcription regulator genes, signaling genes, response to stress genes, metabolic genes, development genes and cell adhesion genes. Conclusions cDNA microarray is an efficient and high-throughout method to survey gene expression profiles in HS.The variation of those gene expressions might be a potential pathogenic mechanism for HS that may offer a novel target for further study of therapeutic strategies of HS.

Objective:To systematically evaluate effects of mobile health intervention on blood pressure control in stroke patients.Methods:PubMed, Embase, CINAHL, PsycINFO, the Cochrane Library, Sinomed, CNKI and Wanfang databases were searched by computer. The search time was from the establishment of databases to October 31, 2020. Two researchers independently searched and screened out RCTs that used Mobile Health to intervene blood pressure in stroke patients according to the inclusion and exclusion criteria of the literature. The revised version of the risk assessment tool for bias was used to evaluate quality of included literatures, and RevMan 5.3 was used to perform a meta-analysis on the extracted data.Results:A total of 5 articles were included, including 1 209 study subjects. Meta-analysis results showed that compared with conventional care, mobile health could reduce the systolic blood pressure of stroke patients [ WMD= -3.59, 95% CI: (-6.00--1.18) , P=0.004]and diastolic blood pressure [ WMD=-3.38, 95% CI: (-5.16- -1.60) , P=0.000 2]. Conclusions:Mobile health is better than conventional care in blood pressure control for stroke patients, but more high-quality RCT studies are still needed to further verify the conclusions in the future. Mobile health is expected to become an effective means to help stroke patients manage their blood pressure in the long-term.

Objective To study CD10 expression in cancer-associated fibroblasts ( CAF ) and related effect on colorectal cancer initiation and progression .Methods A total of 226 surgical removed colorectal cancer specimens were collected with patient follow-up data.A panel of immunohistochemical markers(CD10, Ki-67, p53, cyclin D1 and β-catenin) were evaluated in carcinomas, adjacent adenomas and paired normal colorectal mucosa with correlation of clinicopathological parameters .Results CD10 expression was not detected in the normal colorectal mucosa by immunohistochemistry .The percentages of CD10 expression in CAF were 80.1%(181/226) in carcinoma tissue and 58.4%(132/226) in adjacent adenomas, respectively.SMA was positive and desmin was negative .The proliferation index of Ki-67 was 84.1%(190/226) in tumor tissue, 63.7%(144/226) in adenoma zone, and 7.1% (16/226) in the normal mucosa.The rate of p53 mutation was 50.4% (114/226) in tumor tissue, 53.1%(120/226) in adenoma and 8.8%( 20/226 ) in the normal mucosa. The expression rate of cyclin D1 was 83.6%(189/226) in tumor tissue, 48.7%(110/226)in adenoma zone, but negative in the normal mucosa.For normal tissue , the percentages of β-catenin expression was 53.1%( 120/226 ) , 95.6%( 216/226 ) and 10.6%(24/226) in the cell membrane, cytoplasm and nucleus, respectively.The β-catenin expression in cell membrane, cytoplasm and nucleus was 17.7% ( 40/226 ), 100.0% ( 226/226 ) and 49.1%(111/226), respectively, in the tumor cells.The expression of Ki-67, p53, cyclin D1 andβ-catenin in the tumor cells was positively associated with CD 10 in CAF (P<0.05).The CD10 expression was different in patients with different gender , age and differentiation degree ( P<0.05 ) , whereas the depth of invasion , lymph node metastasis and tumor emboli did not relate to it .Overall survival rates in CD10 negative group were higher than that in CD10 positive group.Conclusions CD10 is only expressed in CAF.Significant correlation is found between CAF with high CD 10 expression and neighboring tumor cells with p 53, Ki-67 and cyclin D1 expression and nuclear β-catenin expression.CD10-positive CAF and p53, β-catenin, cyclin D1 and Ki-67-labelled colorectal cancer cells together with nuclear β-catenin expression may provide helps for diagnosis of colorectal carcinoma from an angle of tumor interstitial microenvironment .CAF with CD10 expression may promote the initiation and progression of colon cancer cells by activating Wnt signaling pathway.

Background and purpose:Epidermal growth factor receptor exon 20 T790M(EGFR T790M)mutation is one of the acquired resistance mechanisms in non-small cell lung cancer(NSCLC)against first-/second-generation EGFR tyrosine kinase inhibitors(EGFR TKIs).Additionally,EGFR T790M mutation can also be observed in NSCLC patients who have not undergone EGFR TKIs treatment.This study aimed to compare the clinical pathological characteristics and prognostic differences between NSCLC patients with de novo and acquired EGFR T790M mutation,and further explore the immune microenvironment features of acquired T790M mutation in NSCLC.Methods:This study retrospectively included 3 762 cases of NSCLC diagnosed at Fudan University Shanghai Cancer Center from April 2020 to September 2022.Among them,2 070 cases(55.02%)exhibited EGFR mutations,and 556 cases(14.77%)received EGFR TKIs treatment.Specifically,there were 119 cases(3.16%)of NSCLC with EGFR T790M mutation,including 51 cases(1.35%)of de novo T790M mutation and 68 cases(1.81%)of acquired EGFR T790M mutation.Clinical data of the patients were collected for comparative analysis between NSCLC patients with de novo and acquired T790M mutation.Multiple immunofluorescence histochemistry(mIHC)was employed to explore the immune microenvironment characteristics of NSCLC patients with acquired T790M mutation.Results:The proportion of de novo and acquired T790M mutations was higher in female patients compared to males.Patients with de novo T790M mutation tended to be younger.Both de novo and acquired T790M mutations were more commonly found in poorly differentiated carcinomas.Among NSCLC patients with de novo T790M mutation,there was a higher rate of programmed death ligand-1(PD-L1)expression(60.00%).In contrast,among NSCLC patients with acquired T790M mutation,the rate of PD-L1 expression was lower(22.39%).Acquired T790M mutation in NSCLC was often accompanied by TP53 alterations(39.7%).Cox regression analysis results indicated that mesenchymal to epithelial transition(MET)factor alteration was a risk factor for the occurrence of acquired T790M mutation(P=0.000 5).The average overall survival(OS)showed no significant difference between de novo and acquired T790M mutations(35.4 and 37.3 months respectively).However,patients with acquired T790M mutation exhibited a higher proportion of recurrence and metastasis.In acquired T790M mutation,there was a higher presence of immune cell infiltration within the stromal compartment,such as CD20+B cells,CD23+B cells,CD8+T cells,CD8+PD-1-/+cells,CD20+PD-1-/+cells and CD23+PD-1-/+cells.Additionally,the study found that when EGFR was accompanied by tumor suppressor gene(TSG)alterations,the average distance between tumor cells and CD8+T cells,CD20+B cells,CD8+PD-1+cells,CD20+PD-1+cells and CD23+PD-1+cells was closer compared to cases with only EGFR mutations.Conclusion:In comparison to patients with de novo T790M mutation,patients with acquired T790M mutation exhibit a lower rate of PD-L1 positivity.Acquired T790M mutation often accompanies TP53 alterations,and MET alteration is identified as a risk factor triggering acquired T790M mutation.Although patients with acquired T790M mutation face higher risk of recurrence and metastasis,their average OS does not significantly differ from those with de novo T790M mutation.In cases of acquired T790M mutation,the presence of TSG mutations can alter the spatial distribution of immune cells,potentially leading to benefits from immunotherapy.

BACKGROUND:Mechanical factors can affect the angiogenic ability of vascular endothelial cells.How the vessel number affects the hydrodynamic properties of microvessels remains to be clarified. OBJECTIVE:To investigate the influence of vessel number on the hydrodynamics of vascular networks based on computational fluid dynamics. METHODS:Three three-dimensional models of vascular network with different vessel numbers were constructed using the Geometry module of ANSYS 19.0 software,and then the vascular network was meshed to tetrahedral elements in Mesh module.The vascular network was assumed to rigid wall without slip,and the blood was assumed to laminar,viscous,and incompressible Newtonian fluid.Blood density,velocity,and a series of blood viscosity coefficients were also established.The Navier-Stokes equation was used for calculation.Hydrodynamic properties of different parts of vascular network with different vessel numbers were analyzed and compared. RESULTS AND CONCLUSION:The streamline,velocity,and mass flow all had the same trend in the vascular network,that is,the outlet and inlet were higher and the middle junction of vascular network was lower.The more the number of vessels,the thinner the blood flow lines in each part of the vascular network.Also,the velocity,mass flow,and wall shear decreased with the increase of the number of blood vessels.Therefore,the changes in vessel number could influence the hydrodynamic environment in the vascular network.Computational fluid dynamics indicates that the changes in vessel numbers can influence the hydrodynamic properties of blood,and provides a new idea for treating bone hypoperfusion-induced diseases(fracture nonunion,bone defect,osteoporosis,etc.)through tonifying kidney and activating blood circulation based on the coupling between angiogenesis and osteogenesis.

To investigate the expression of CD10 in tumor-associated fibroblasts (TAF) in colorectal adenomas and its relation to cancerization and recurrence of adenoma.Tissue samples of low-grade adenoma (=50), high-grade adenoma (=50) and colorectal adenocarcinoma (=50) were collected, and tissue samples at the distal margin of corresponding colorectal lesions were taken as controls. The expression of CD10 in the stromal TAFs, and the expressions of β-catenin, Ki-67, p53 and CyclinD1 in tumor cells were detected by immunohistochemistry (Envision). The correlation of CD10 expression in stromal TAFs with the expressions of β-catenin, Ki-67, p53 and CyclinD1 in tumor cells was analyzed by Spearmen. One hundred samples of low-grade colorectal adenoma were collected, including 57 non-recurrent cases and 43 recurrent cases (16 cases of recurrent adenoma and 27 cases of recurrent adenocarcinoma); the expression of stromal TAF CD10 were determined and compared among groups.There was no TAF in normal colorectal mucosa. The expression rates of TAF CD10 in low-grade adenoma, high-grade adenoma and colorectal adenocarcinoma were 22%, 50% and 78%, respectively (all<0.05). The expression of Ki-67 and β-catenin in low-grade adenoma, high-grade adenoma, colorectal adenocarcinoma was on a rising trend (all<0.01). The expression of CyclinD1 in high-grade adenoma was higher than that in colorectal adenocarcinoma and low-grade adenoma (all>0.05). The expression of p53 in colorectal adenocarcinoma and high-grade adenoma was higher than that in low grade adenoma (all<0.01). The expression of TAF CD10 was correlated with the expression of p53, Ki-67 and β-catenin-nucleus(=0.264、0.307、0.320, all<0.01),but not correlated with CyclinD1 and β-catenin-membrane (=0.012、-0.073, all>0.05). The TAF CD10 level was significantly higher in low-grade adenoma with recurrence than that in those without recurrence (<0.05).The expression of CD10 in recurrent colorectal adenocarcinoma was higher than that in recurrent adenoma (<0.05).The expression of TAF CD10 is increased gradually in the process of adenoma-cancer, indicating that it may play an important role in the canceration of adenoma. Adenomas with high expression of CD10 TAF are likely to be recurrent and cancerized, and detection of TAF CD10 combined with p53, Ki-67 and β-catenin may be of value in predicting canceration or recurrence of colorectal adenoma.

The construction of the comprehensive evaluation index system of the famous classical formula preparations after the marketing has both theoretical and practical significance. In this study， literature related to the post-marketing comprehensive evaluation of traditional Chinese medicine（TCM） compound preparations was retrieved from China National Knowledge Infrastructure（CNKI）， China Science and Technology Journal Database（VIP）， Wanfang Data Knowledge Service Platform（WanFang） and SinoMed from January 1， 2000 to April 30， 2022. CiteSpace 6.1.R2， a scientometrics software， was used to visualize the keywords involved， and to analyze the dynamic evolution trend and research hotspots in this field. Then， the existing comprehensive post-marketing evaluation index system of TCM compound preparations was screened and extracted， and the research status was systematically analyzed by mathematical statistics. It was found that there were problems such as the generalized boundaries between assessment dimensions and assessment elements， the lack of data sources for individual evaluation indexes， unset weight of some index system and insufficient application degree. In addition， according to the characteristics of famous classical formulas， the authors discuss the importance of evidence evaluation based on combination of disease and syndrome， pharmacovigilance of famous classical formulas preparations， and whole-process quality control of famous classical formulas， and put forward the construction strategy of comprehensive post-marketing evaluation of the famous classical formula preparations， which is oriented by clinical value， centered on evidence evaluation， and guaranteed by the whole-process quality control.
