Climate change: approach to intervention using expression vector for carbonic anhydrase via glycosylphosphatidylinositol.

Climate change is a change in the usual weather found in a place. The climate change has a major impact not only on natural disasters of the Earth but also on human health. The climate crisis is then no longer a future concern. It includes both the global warming driven by human emissions of greenhouse gases (GHG), and the resulting large-scale shifts in weather patterns. Global warming can occur from a variety of causes, both natural and human induced. The primary GHG in Earth's atmosphere, listed in decreasing order of average global mole fraction, are: water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). Today, scientists around the world continue to try and solve the puzzle of climate change. It is clear that to address climate change, the amount of CO2 released into the atmosphere by industrial process has to be reduced because once it is added to the atmosphere, it can continue to affect climate for thousands of years. For such a purpose, an approach to intervention using expression vectors for any protein targeting to the cell plasma membrane via the glycosylphosphatidylinositol, GPI, anchor is suggested. The resulting GPI-anchored proteins would be useful for studying intermolecular interactions, especially gene-environment interactions, in investigating the potential impact of any chemical compounds on any genes of interest and could be used for carbonic anhydrase (CA)-based CO2-capture (environmental application). This approach would be crucial not only for capturing CO2 via GPI and CA but also for the production of CA enzyme as well as its stabilization and therefore useful for combating the global warming of climate change.

Intratumoral delivery of a Tim-3 antibody-encoding oncolytic adenovirus engages an effective antitumor immune response in liver cancer.

BACKGROUND AND PURPOSE: The use of oncolytic viruses as a gene therapy vector is an area of active biomedical research, particularly in the context of cancer treatment. However, the actual therapeutic success of this approach to tumor elimination remains limited. As such, the present study was developed with the goal of simultaneously enhancing the antitumor efficacy of oncolytic viruses and the local immune response by combining the Ad-GD55 oncolytic adenovirus and an antibody specific for the TIM-3 immune checkpoint molecule (α-TIM-3). APPROACH AND KEY RESULTS: The results of Virus and cell-mediated cytotoxicity assay, qPCR, and Western immunoblotting showed that Ad-GD55-α-Tim-3 oncolytic adenovirus is capable of inducing α-TIM-3 expression within hepatoma cells upon infection, and Ad-GD55-α-TIM-3 exhibited inhibitory efficacy superior to that of Ad-GD55 when used to treat these tumor cells together with the induction of enhanced intracellular immunity. In vivo experiments revealed that Ad-GD55-α-TIM-3 administration was sufficient to inhibit tumor growth and engage in a more robust local immune response within the simulated tumor immune microenvironment. CONCLUSION AND IMPLICATIONS: These results highlighted the promising therapeutic effects of Ad-GD55-α-TIM-3 oncolytic adenovirus against HCC in vitro and in vivo. As such, this Ad-GD55-α-TIM-3 oncolytic adenovirus may represent a viable approach to the treatment of hepatocellular carcinoma.

Efficacy and safety of a sequential treatment with clearing heat and eliminating phlegm and tonifying and activating blood circulation in treating acute ischemic stroke: study protocol for a randomized controlled trial.

OBJECTIVE: To investigate the short-term efficacy and safety outcomes following a sequential treatment with clearing heat and eliminating phlegm (CHEP) formula and tonifying Qi and activating blood circulation (TQABC) formula in patients with acute ischemic stroke (AIS) within a 72 h time window. METHODS: In this randomized, multicenter, double-blinded, placebo-controlled trial, 500 participants will be randomly assigned in a ratio of 1∶1 to the CHEP+ TQABC group or control group. In addition to guideline-based standard medical care, participants in the treatment group will receive the CHEP formula for the first 5 consecutive days followed by the TQABC formula for another 10 consecutive days, while those in the control group will receive CHEP formula placebo and TQABC formula placebo consecutively. The primary outcome measure will be the comparison of the change in the National Institutes of Health Stroke Scale score from baseline to 15 days after randomization. The secondary outcome measures will include the scores on the modified Rankin Scale, Barthel Index, Patient-Reported Outcomes, TCM symptom pattern (Zheng-hou) evaluation Scale, and the incidence of in-hospital complications. Safety assessment will include the physical examination, laboratory detection, any adverse events or serious adverse events, and the proportion of any complications during hospitalization. DISCUSSION: The results of this study will provide objective and scientific data with which to assess the efficacy and safety of a sequential treatment based on "integrating disease and symptom pattern" for patients with AIS.

Far space neglect in left spatial neglect patients: features and assessment / 中国康复理论与实践

ObjectiveTo explore the features and assessment for far space neglect in left spatial neglect patients after right brain stroke. MethodsFrom January to October, 2021, 30 left unilateral spatial neglect (USN) patients after right stroke (patients, n = 30) from Beijing Bo'ai Hospital and healthy volunteers matching with gender, age and level of education (controls, n = 30) were evaluated with line cancelation (LC), star cancelation (SC) and line bisection (LB) tests, nearly and far away. The 25 controls were evaluated with LB on the second day. ResultsNo line or star was omissed in the controls. Both the deviation and percentage were more in the patients than in the controls (|t| > 4.319, P < 0.001). Both the deviation and percentage were less different for all the test (|Z| < 1.638, t = -1.282, P > 0.05) between nearly and far away, except the deviation of LB (t = -4.994, P < 0.001). The ICC of test-retest was above 0.462 (P < 0.01). ConclusionRight brain stroke patients with USN may present far spatial neglect, which can be assessed with LB.

Factors influencing the executive functioning of patients with acquired brain injury / 中华物理医学与康复杂志

Objective:To explore the factors influencing executive functioning after a brain injury and analyze the relationship between executive functioning and other cognitive functions.Methods:Forty-six brain injury survivors were given the Executive Function Performance Task (EFPT) assessment and the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA). The scores and time of the EFPT tasks, and the orientation, perception, visual motor organization, thinking, and attention and concentration results in the LOTCA were observed. Regression analysis compared the males and females, those younger and older than 40, those with more or less than 12 years of education, trauma and stroke survivors, as well as those with left, right and bilateral lesion to isolate the factors most influencing executive functioning.Results:The average EFPT score on the cooking task, the medication score and the total score of the young group were all significantly higher than those of the older group. Their telephone time, medication time and bill payment time were all significantly shorter. Those with more than 12 years of education had average scores on the cooking, bill payment and EFPT significantly higher than those with less than 12 years of education. The average bill paying and total EFPT scores of the brain trauma group were significantly higher than the stroke group′s averages. No significant differences were observed between the different genders or those with different injury sites. Age was the strongest predictor of total EFPT scores. Except for the medication scores, the average scores of the other three tasks and the total score of EFPT were moderately correlated with the visual motor organization, thinking, attention and concentration, and total LOTCA scores, with correlation coefficients ranging from 0.31 to 0.64.Conclusions:Older persons and those will less education tend to have worse executive functioning. Traumatic damage to executive functioning is more serious than that caused by stroke. Executive functioning is closely related to visual-motor organization, and to the ability to think, attend and concentrate.

Panx1 Promotes Cisplatin-induced Apoptosis of A549 Cells by Regulating ATP/IP3 Pathway / 肿瘤防治研究

Objective To observe the regulation of Panx1 on ATP/IP3 signaling pathway and its mechanism during cisplatin-induced apoptosis of lung adenocarcinoma cells. Methods Human lung adenocarcinoma cell line A549 was used as the research object and carbenoxolone (CBX) was used as a drug interference tool. A549 cells were divided into normal control group, the CBX group, the cisplatin (DDP) group and the CBX+DDP group. MTT assay and Annexin V/PI assay were used to detect the survival and apoptosis rates of A549 cells. The relative concentrations of extracellular adenosine triphosphate (ATP) and intracellular inositol triphosphate (IP3) were measured by Chemiluminescence and ELISA. Results Compared with DDP group, the cell survival rate of CBX+DDP group increased, while the early and late apoptotic rates and the release concentration of extracellular ATP and intracellular IP3 decreased (all P < 0.01). Conclusion Panx1 can increase the sensitivity of lung adenocarcinoma cells to cisplatin by regulating the ATP/IP3 signaling pathway.

Synthesis and antitumor activity of pefloxacin C-3 methylene rhodanine devatives / 中国药科大学学报

@#To further explore an efficient strategy for the construction of antitumor fluoroquinolone molecules from antibacterial fluoroquinolone drugs, twelve new title compounds, 1-ethyl-6-fluoro-7-(4-methyl-piperazin-1-yl)-3-(3-substituted-rhodanin-5-ylidene)methyl-quinolon-4(1H)-ones(6a-6l), was designed and synthesized with α, β-unsaturated ketone scaffold and a rhodanine ring as an isostere and fused modified group, respectively, from pefloxacin(1), and their structures were characterized by elemental analysis and spectral data. The in vitro anti-cell proliferative activity of the title compounds against the tested A549, Hep-3B and HL60 cancer cells exhibited more significant potency than parent 1. In particular, halogenated phenyl title compounds(6d, 6e, 6f)displayed a comparable activity to comparison doxorubicin against A549 cells and low cytotoxicity against normal Vero cells. Thus, a methylene rhodanine scaffold as a bioisostere of the C-3 carboxylic acid group have shown to be beneficial to improving the antitumor activity.

Synthesis and antitumor activity of fluoroquinolone C-3 s-triazole Schiff-base carboxylic acid derivatives from pefloxacin (X) / 中国药科大学学报

To explore a new strategy for further optimization to the C-3 bioisteric heterocyclic ring of fluoroquinolones,twelve novel fluoroquinolone C-3 s-triazole Schiff-base carboxylic acid derivatives(7a-71) were designed and synthesized with both functionalized sulfanylacetic acid and Schiff-base moieties as the modified side-chain for the C-3 bioisosteric s-triazole ring of pefloxacin(1).The structures were characterized by elemental analysis and spectral data,and the in vitro anti-tumor activity of the title compounds against SMMC-7721,L1210 and HL60 cell lines was evaluated.The preliminary pharmacological results demonstrated that the title compounds possessed more significantly anti-proliferative activity than either the parent 1 or the corresponding amine intermediates(6).In particular,the title compound bearing a fluorine atom (7j) and compound bearing a nitro group attached to benzene ring (71) were comparable to the control doxorubicin against SMMC-7721 cells with an IC50 value of micro-molar concentration,respectively.It suggests that s-triazole ring modified with functional side-chain moieties instead of the C-3 carboxylic group is favorable to the improvement of antitumor activity.

Effect of metformin on the insulin resistance in a rat model of type 2 diabetes mellitus / 中国组织工程研究

BACKGROUND:More than 10 kinds of lipid metabolism-related genes have been found, and endocrine dysfunction mediated by these genes is an important pathological basis for the occurrence and development of insulin resistance. OBJECTIVE:To investigate the effects of metformin on serum lipid profiles and the expression levels of various genes associated with insulin resistance, as well as the histopathological changes of the liver and pancreas in rats with type 2 diabetes melitus. METHODS:A type 2 diabetes mellitus rat model was established by feeding a high-fat diet to the rats for 4 weeks, combined with the intraperitoneal injection of streptozotocin (35 mg/kg). In the meanwhile, metformin was administered orally (400 mg/kg?d) (model group) or nothing (control group). Semi-quantitative RT-PCR, histopathological and biochemical examinations were then performed. RESULTS AND CONCLUSION:Metformin improved the symptoms of insulin resistance by normalizing the serum lipid profiles in the diabetic rats. Furthermore, metformin upregulated the expression levels of insulin receptors and genes associated with lipid metabolism, including acyl-CoA oxidase, carnitine palmitoyl transferase-1 and peroxisome proliferator activated receptor-α. In addition, metformin downregulated the expression levels of fetuin-A and retinol binding protein-4, and improved the expression of perilipin that had been reduced in the type 2 diabetes mellitus rats. Metformin was shown to induce positive signaling for insulin and the regeneration of pancreaticβcells in the pancreas. These results suggest that metformin ameliorates the insulin resistance induced by type 2 diabetes mellitus via regulating the expression levels of fetuin-A, retinol binding protein-4, perilipin and various genes associated with lipid metabolism.
