Expression of CD24 gene in human malignant pleural mesothelioma and its relationship with prognosis / 中华劳动卫生职业病杂志

Objective: To investigate the expression of CD24 gene in human malignant pleural mesothelioma (MPM) cells and tissues, and evaluate its relationship with clinicopathological characteristics and clinical prognosis of MPM patients. Methods: In February 2021, UALCAN database was used to analyze the correlation between CD24 gene expression and clinicopathological characteristics in 87 cases of MPM patients. The TIMER 2.0 platform was used to explore the relationship between the expression of CD24 in MPM and tumor immune infiltrating cells. cBioportal online tool was used to analyze the correlation between CD24 and MPM tumor marker gene expression. RT-qPCR was used to analyze the expressions of CD24 gene in human normal pleural mesothelial cell lines LP9 and MPM cell lines NCI-H28 (epithelial type), NCI-H2052 (sarcoma type), and NCI-H2452 (biphasic mixed type). RT-qPCR was performed to detect the expressions of CD24 gene in 18 cases of MPM tissues and matched normal pleural tissues. The expression difference of CD24 protein in normal mesothelial tissue and MPM tissue was analyzed by immunohistochemistry. A Kaplan-Meier model was constructed to explore the influence of CD24 gene expression on the prognosis of MPM patients, and Cox regression analysis of prognostic factors in MPM patients was performed. Results: The CD24 gene expression without TP53 mutation MPM patients was significantly higher than that of patients in TP53 mutation (P<0.05). The expression of CD24 gene in MPM was positively correlated with B cells (r(s)=0.37, P<0.001). The expression of CD24 gene had a positive correlation with the expressions of thrombospondin 2 (THBS2) (r(s)=0.26, P<0.05), and had a negative correlation with the expression of epidermal growth factor containing fibulin like extracellular matrix protein 1 (EFEMP1), mesothelin (MSLN) and calbindin 2 (CALB2) (r(s)=-0.31, -0.52, -0.43, P<0.05). RT-qPCR showed that the expression level of CD24 gene in MPM cells (NCI-H28, NCI-H2052 and NCI-H2452) was significantly higher than that in normal pleural mesothelial LP9 cells. The expression level of CD24 gene in MPM tissues was significantly higher than that in matched normal pleural tissues (P<0.05). Immunohistochemistry showed that the expressions of CD24 protein in epithelial and sarcoma MPM tissues were higher than those of matched normal pleural tissues. Compared with low expression of CD24 gene, MPM patients with high expression of CD24 gene had lower overall survival (HR=2.100, 95%CI: 1.336-3.424, P<0.05) and disease-free survival (HR=1.800, 95%CI: 1.026-2.625, P<0.05). Cox multivariate analysis showed that compared with the biphasic mixed type, the epithelial type was a protective factor for the prognosis of MPM patients (HR=0.321, 95%CI: 0.172-0.623, P<0.001). Compared with low expression of CD24 gene, high expression of CD24 gene was an independent risk factor for the prognosis of MPM patients (HR=2.412, 95%CI: 1.291-4.492, P=0.006) . Conclusion: CD24 gene and protein are highly expressed in MPM tissues, and the high expression of CD24 gene suggests poor prognosis in MPM patients.

@#AIM: To evaluate the clinical efficacy of local application of triamcinolone acetonide combined with mouse nerve growth factor in the treatment of infraorbital nerve injury after infraorbital wall fracture.METHODS: Forty-three patients(43 eyes)with infraorbital wall fractures who underwent infraorbital wall fracture revision from April 2020 to February 2021 at the Affiliated Eye Hospital of Nanchang University were prospectively analyzed. Patients were randomly divided into two groups, in which 20 patients(20 eyes)in the experimental group had gelatin sponges infiltrated with triamcinolone acetonide and mouse nerve growth factor placed on the nerve injury intraoperatively; 23 patients(23 eyes)in the control group had no special treatment intraoperatively. At 6mo postoperative follow-up, the results of quantitative sensory testing(two-point localization, nociception, and touch)were compared between the affected and healthy lower lid areas, and the results were reported in an asymmetry index(AI).RESULTS: Baseline results showed no significant differences between the two groups in terms of gender, age, time of injury, and preoperative sensory testing between the two groups(all <i>P</i>>0.05). The AI values of two-point localization sensation, tactile sensation, and pain sensation in both groups were higher at 1wk after surgery than before surgery(all <i>P</i><0.05), and the symptoms of sensory impairment were aggravated, with different degrees of improvement at 1mo after surgery and statistically significant differences in pain sensation at 3mo after surgery(<i>P</i><0.05), and two-point localization sensation, tactile sensation, and pain sensation were significantly improved at 6mo after surgery than before treatment(all <i>P</i><0.01). At 1mo after surgery, the differences in two-point localization sensation and pain sensation in the test group were statistically significant compared with the control group(<i>t</i>=-2.082,-2.143; <i>P</i>=0.044, 0.038). At 3mo after surgery, there was a statistically significant difference in nociception in the test group compared to the control group(<i>t</i>=-2.118, <i>P</i>=0.04). At 6mo after surgery, there was no statistically significant difference in quantitative sensory testing between the two groups(<i>P </i>>0.05).CONCLUSION: Local application of triamcinolone acetonide combined with mouse nerve growth factor for the treatment of infraorbital nerve injury after infraorbital wall fracture was effective in early internal recovery and superior to the group without special intraoperative treatment.

Material basis and molecular mechanism of Angelicae Sinensis Radix in activating blood:based on computer-aided drug design / 中国中药杂志

Angelicae Sinensis Radix excels in activating blood, but the scientific mechanism has not been systematically analyzed, thus limiting the development of the medicinal. This study employed the computer-aided drug design methods, such as structural similarity-based target reverse prediction, complex network analysis, molecular docking, binding free energy calculation, cluster analysis, and ADMET(absorption, distribution, metabolism, excretion, toxicity) calculation, and enzyme activity assay in vitro, to explore the components and mechanism of Angelicae Sinensis Radix in activating blood. Target reverse prediction and complex network analysis yielded 40 potential anticoagulant targets of the medicinal. Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis indicated that the targets mainly acted on the complement and coagulation cascade signaling pathway to exert the anticoagulant function. Among them, the key enzymes thrombin(THR) and coagulation factor Xa(FXa) in coagulation cascade and thrombosis were the drug targets for thromboembolic diseases. At the same time, molecular docking and cluster analysis showed that the medicinal had high selectivity for FXa. According to binding free energy score, 8 potential active components were selected for enzyme activity assay in vitro. The results demonstrated that 8 components inhibited THR and FXa, and the inhibition was stronger on FXa than on THR. The pharmacophore model of 8 active compounds was constructed, which suggested that the components had the common pharmacophore AAHH. The ADMET calculation result indicated that they had good pharmacokinetic properties and were safe. Based on target reverse prediction, complex network analysis, molecular docking and binding free energy calculation, anticoagulant activity in vitro, spatial binding conformation of molecules and targets, pharmacophore model construction, and ADMET calculation, this study preliminarily clarified the material basis and molecular mechanism of Angelicae Sinensis Radix in activating blood from the perspective of big data, and calculated the pharmacology and toxicology parameters of the active components. Our study, for the first time, revealed that the medicinal had obvious selectivity and pertinence for different coagulation proteins, reflecting the unique effect of different Chinese medicinals and the biological basis. Therefore, this study can provide clues for precision application of Angelicae Sinensis Radix and the development of the blood-activating components with modern technology.

Tryptophan 2,3-dioxygenase 2 controls M2 macrophages polarization to promote esophageal squamous cell carcinoma progression

Tryptophan 2,3-dioxygnease 2 (TDO2) is specific for metabolizing tryptophan to kynurenine (KYN), which plays a critical role in mediating immune escape of cancer. Although accumulating evidence demonstrates that TDO2 overexpression is implicated in the development and progression of multiple cancers, its tumor-promoting role in esophageal squamous cell carcinoma (ESCC) remains unclear. Here, we observed that TDO2 was overexpressed in ESCC tissues and correlated significantly with lymph node metastasis, advanced clinical stage, and unfavorable prognosis. Functional experiments showed that TDO2 promoted tumor cell proliferation, migration, and colony formation, which could be prevented by inhibition of TDO2 and aryl hydrocarbon receptor (AHR). Further experimentation demonstrated that TDO2 could promote the tumor growth of KYSE150 tumor-bearing model, tumor burden of C57BL/6 mice with ESCC induced by 4-NQO, enhance the expression of phosphorylated AKT, with subsequent phosphorylation of GSK3

<p><b>BACKGROUND</b>Few studies have given suggestions on appropriate initiation insulin dosage when combined with oral antidiabetic drugs (OADs). This research was to investigate appropriate initiation insulin doses for insulin-naive type 2 diabetes patients with different combinations and the relationship between insulin dosage and relevant factors.</p><p><b>METHODS</b>This was a randomized, open-label, treat to target study. The target was 20% decrease of both fasting plasma glucose (FPG) and 2 hours post-breakfast blood glucose (P2hBG). One hundred and forty-seven insulin-naive Chinese patients recruited were randomly assigned to 3 groups: group A, patients received insulin monotherapy; group B, received insulin plus metformin (0.5 g, tid) and group C, received insulin plus metformin (0.5 g, tid) and pioglitazone (15 mg, qd). Insulin doses were initiated with a dose of 0.3 U×kg(-1)×d(-1) and titrated according to FPG and P2hBG till reached the targets.</p><p><b>RESULTS</b>Both the time of getting 20% reduction of FPG and P2hBG showed significant differences among the three groups. The time was shortest in Group C. The insulin doses needed to achieve glucose reduction of 20% in three treatment groups were (0.40 ± 0.04) U×kg(-1)×d(-1) for Group A, (0.37 ± 0.04) U×kg(-1)×d(-1) for Group B, and (0.35 ± 0.03) U×kg(-1)×d(-1) for Group C, respectively. Multiple linear stepwise regression analysis showed that insulin doses correlated with body weight, FPG, diabetes duration, age and history of sulfonylurea treatment. The standardized regression coefficients were 0.871, 0.322, 0.089, 0.067 and 0.063 (with all P < 0.05).</p><p><b>CONCLUSIONS</b>To achieve blood glucose's reduction of 20% within safety context, initial insulin doses were recommended as the following: 0.40 U×kg(-1)×d(-1) for insulin mono-therapy, 0.37 U×kg(-1)×d(-1) for insulin plus metformin treatment, and 0.35 U×kg(-1)×d(-1) for insulin plus metformin and pioglitazone treatment in Chinese type 2 diabetes outpatients. Body weight is found the most closely related factor to the insulin dosage.</p>

Objective To establish the tissue culture system of Cynanchum otophylum in genetic transformation. Methods Asepsis seedling was set up by using different explant parts, disinfectors, and disinfecting time. The callus was induced, breeded, and differentiated by using different media, different hormone categories and combinations, and different hormone concentrations of 2,4-D and KT. Results It was the best method that asepsis seeding was built up by using seed as the explant and using 10% NaClO to treat the seed for 20—30 min or using 0.2% HgCl2 to treat the stem for 3 min. The seed, root, stem, and leaf of C. otophylum can form callus easily. The 2,4-D was important in forming callus. C. otophylum was more sensitivity to KT. The effect was better when KT was used to induce callus or adventitious buds. MS+2,4-D 1.0 mg/L+KT 1.0 mg/L was the better medium to induce callus to form. The callus cant be induced to form adventitous buds without reference to using seed or root, stem, and leaf as the explant, without reference to using hormone 6-BA or KT, ZT, 2ip. Gentamicin 100 ?g/mL is the optimum pressure in genetic transformation of C. otophylum. Conclusion The seed or stem is the ideal material bombarded by particle gun that is induced to form callus for 14 d in the media MS+2, 4-D 1.0 mg/L+KT 1.0 mg/L and without forming adventitious buds.
