Optimization of Menin inhibitors based on artificial intelligence-driven molecular factory technology / 中国药科大学学报

@#Abstract: The new generation of artificial intelligence technology, represented by deep learning, has emerged as a crucial driving force in the advancement of new drug research and development. This article creatively proposes a workflow named “Molecular Factory” for the design and optimization of drug molecules based on artificial intelligence technology. This workflow integrates intelligent molecular generation models, high-performance molecular docking algorithms, and accurate protein-ligand binding affinity prediction methods. It has been integrated as a core module into DrugFlow, a one-stop drug design software platform, providing a comprehensive set of mature solutions for the discovery and optimization of lead compounds. Utilizing the “Molecular Factory” module, we conducted the research of second-generation inhibitors against Menin that can combat drug resistance. Through the integration of computational and experimental approaches, we rapidly identified multiple promising compounds. Among them, compound RG-10 exhibited the IC50 values of 9.681 nmol/L, 233.2 nmol/L, and 40.09 nmol/L against the wild-type Menin, M327I mutant, and T349M mutant, respectively. Compared to the positive reference molecule SNDX-5613, which has entered Phase II clinical trials, RG-10 demonstrated significantly enhanced inhibitory activity against the M327I and T349M mutants. These findings fully demonstrate the unique advantages of the "Molecular Factory" technology in practical drug design and development scenarios. It can rapidly and efficiently generate high-quality active molecules targeting specific protein structures, holding significant value and profound implications for advancing new drug discovery.

OBJECTIVE:To review the latest research progress of osteoarthritis related cytokines and signaling pathways in recent years,such as the mechanism of action and treatment modalities,in order to provide a basis for future exploration of new therapeutic targets and modalities. METHODS:Literature search was conducted on CNKI,WanFang,VIP,PubMed,Web of Science,and Medline databases.Chinese search terms were"osteoarthritis,cytokines,signal pathway,chondrocyte,inflammation,treatment".Finally,60 papers were included for review. RESULTS AND CONCLUSION:(1)In current studies,it is believed that the specific mechanism of osteoarthritis is not clear,and a large number of studies have shown that osteoarthritis is strongly associated with cytokines and signaling pathways,which is a complex process of action.Relevant studies taking cytokines and signaling pathways as therapeutic breakthroughs are also the current hot spot.(2)The receptor antagonists of pro-inflammatory factors such as interleukin 1 are not effective in the treatment of osteoarthritis,and more studies turn to gene therapy.(3)The therapeutic methods of transforming growth factor β,recombinant factors of Wnt signaling pathway,gene therapy and mesenchymal stem cells have obtained positive research results.However,basic and clinical studies on safety and efficacy are likely to be conducted in future studies.(4)At present,relevant therapeutic methods such as platelet-rich plasma have been widely used in clinical practice,while recombinant factor,gene therapy and mesenchymal stem cell therapy are all in the research stage,among which mesenchymal stem cell therapy and gene therapy are expected to make breakthroughs in the field of cartilage repair and regeneration,and are worthy of expectation in the future.However,more clinical and basic studies are needed to verify its effectiveness and safety,explore its mechanism of action and scope of application,and set standards for its clinical use.

Efficacy and safety of different applications of tranexamic acid in high tibial osteotomy / 中国组织工程研究

BACKGROUND:High tibial osteotomy results in massive blood loss during the perioperative period.Tranexamic acid can effectively reduce perioperative blood loss.However,the method of tranexamic acid application has not been unified. OBJECTIVE:To investigate the effect and safety of different methods of tranexamic acid on perioperative blood loss in the high tibial osteotomy. METHODS:A total of 160 patients who underwent primary unilateral high tibial osteotomy in the Binzhou Medical University Hospital from January 2019 to December 2021,including 69 males and 91 females,were randomly divided into four groups(n=40 per group).Among them,40 patients were given an intravenous infusion of saline containing 2 g tranexamic acid 10 minutes before tourniquet release(venous group);40 patients were given an intravenous infusion of 1 g tranexamic acid and 1 g tranexamic acid was injected through a drainage tube after the closure of the incision(combined group);40 patients were given 2 g tranexamic acid infusion into drainage tube after the closure of the incision(perfusion group);an additional 40 patients were given an intravenous infusion of the same amount of normal saline(blank group).The general information was compared among the four groups of patients.The hemoglobin,hematocrit,intraoperative blood loss,drainage volume,blood transfusion rate,incision complication,and the incidence of deep vein thrombosis were recorded on days 1,3 and 5 after operation in the four groups.The total blood loss and hidden blood loss were calculated. RESULTS AND CONCLUSION:(1)There was no statistically significant difference in general information among the four groups.(2)No significant difference was found in intraoperative blood loss among the four groups.(3)The maximum decreased values of hemoglobin and hematocrit on days 1,3 and 5 after operation,drainage volume,total blood loss and hidden blood loss were all ranked as the combined group<venous group<perfusion group<blank group.(4)The postoperative blood transfusion rate of the blank group was significantly higher than that of the other three groups,and there was no significant difference in the postoperative blood transfusion rate among the combined group,the venous group and the perfusion group.(5)There was no significant difference in the incidence of venous thrombosis and incision complications among the four groups.(6)It is indicated that the application of tranexamic acid in high tibial osteotomy can reduce perioperative bleeding and postoperative blood transfusion rate,and the effect of intravenous infusion combined with drainage tube perfusion is better,which does not increase the incidence of venous thrombosis and incision complications.

Imaging analysis of anatomical morphological risk factors for posterior cruciate ligament injury of the knee / 中国组织工程研究

BACKGROUND:Studies have shown that posterior cruciate ligament injuries are associated with the anatomical morphology of the knee joint. OBJECTIVE:To explore anatomical morphological risk factors for posterior cruciate ligament injury. METHODS:The imaging data of 142 patients who visited Affiliated Hospital of Binzhou Medical University for knee joint problems from January 2015 to August 2022 were retrospectively analyzed.They were divided into posterior cruciate ligament injury group(n=71,including 49 males and 22 females)and posterior cruciate ligament intact group(n=71,including 49 males and 22 females).Intercondylar notch width,intercondylar notch height,bicondyle width,notch width index,angle of intercondylar notch,Blumensaat's line inlication angle,medial tibial spine height,lateral tibial spine height,tibial spine width,tibiofemoral consistency index,tibial plateau anterior-posterior diameter,medial tibial depth and patellar tendon-tibial shaft angle were measured on MRI images.Posterior tibial slope was measured on X-ray images.The above indicators were included in the logistic regression analysis for investigation. RESULTS AND CONCLUSION:(1)Univariate logistic regression analysis in men showed that tibial spine width,tibiofemoral consistency index,medial tibial depth,and posterior tibial slope were associated with posterior cruciate ligament injury(P<0.05).Multivariate binary logistic regression analysis showed that tibiofemoral consistency index and medial tibial depth were associated with posterior cruciate ligament damage(P<0.05).(2)Univariate logistic regression analysis in women showed that medial tibial spine height,lateral tibial spine height,tibial spine width,and posterior tibial slope were associated with posterior cruciate ligament injury(P<0.05).Multivariate binary logistic regression analysis showed that posterior tibial slope was associated with posterior cruciate ligament damage(P<0.05).(3)The receiver operating characteristic curve showed that tibiofemoral consistency index,medial tibial depth and posterior tibial slope had a certain predictive value on posterior cruciate ligament damage.(4)These findings suggest that anatomical morphological risk factors for posterior cruciate ligament injury differ between men and women,and tibial spine width and posterior tibial slope are common risk factors.In the male population,abnormal tibial spine width,tibiofemoral consistency index,medial tibial depth,and posterior tibial slope are easy to induce posterior cruciate ligament injury.In the female population,abnormal medial tibial spine height,lateral tibial spine height,tibial spine width,and posterior tibial slope are easy to induce posterior cruciate ligament injury.Clinicians can use the above risk factors to identify abnormal knee morphology,assess people at risk of posterior cruciate ligament injury,and provide preventive advice and guidance for treatment.

Applications and advancements of instrumental variable approach in causal inference in environmental epidemiology / 环境与职业医学

In environmental epidemiological research, extensive non-random environmental exposures and complex confounding biases pose significant challenges when attempting causal inference. In recent years, the introduction of causal inference methods into observational studies has provided a broader range of statistical tools for causal inference research in environmental epidemiology. The instrumental variable (IV) approach, as a causal inference technique for effectively controlling unmeasured confounding factors, has gradually found application in the field of environmental epidemiological research. This article reviewed the basic principles of IV and summarized the current research progress and limitations of applying IV for causal inference in environmental epidemiology. IV application in the field of environmental epidemiology is still in the initial stage. Rational use of IV and effective integration with other causal inference methods will become the focus of the development of causal inference in environmental epidemiology. The aim of this paper is to provide a methodological reference and basis for future studies involving causal inference to target population health effects of environmental exposures in China.

Diagnosis and treatment procedures and health management for patients with hereditary angioedema / 中华预防医学杂志

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Preliminary insights into the practice of hypoallergenic home visiting program / 中华预防医学杂志

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

Methods: A total of 1 060 registered nasopharyngeal carcinoma patients were followed up for survival outcomes until December 31, 2021. Observed survival rate (OSR) and relative survival rate (RSR) was calculated by Hakulinen method in SURV3.01 software, and Hakulinen's likelihood ratio test was used for statistical difference comparison. Age-standardized relative survival rate (ARSR) was calculated according to the International Cancer Survival Standard (ICSS). Joinpoint 4.7.0.0 software was used to conduct the annual average percentage change (AAPC) in nasopharyngeal carcinoma survival rate. The period from 1972 to 2016 is divided into 9 periods for grouping processing according to 5 years. Results: The OSR of nasopharyngeal carcinoma at 1, 5, 10 years were 63.02%, 34.70% and 24.72%, the RSR at 1, 5, 10 years were 64.44%, 38.98% and 31.64%, respectively. The uptrends of RSR in the nine periods were statistically significant (χ(2)=112.16, P<0.001). The 1, 5, 10 years RSR for males were 62.66%, 35.89% and 27.94%, while the 1, 5, 10 years RSR for females were 68.30%, 45.67% and 39.68%, respectively. There was no statistically significant difference in RSR between males and females (χ(2)=14.16, P=0.656). The 5-year RSR for the age groups of 25-34, 35-44, 45-54, 55-64, 65-74, and over 75 years old were 52.83%, 40.92%, 42.64%, 38.65%, 27.23% and 28.88%, respectively. There was a statistically significant difference in RSR among different age groups (χ(2)=42.33, P=0.003). Moreover, the ARSR of nasopharyngeal carcinoma at 1, 5, 10 years were 63.64%, 37.33% and 27.10%, for males were 61.82%, 35.60% and 25.20%, for females were 68.36%, 43.12% and 32.93%. Period trend showed that the AAPC of 5-ARSR was 2.71% (t=7.47, P<0.001) from 1972 to 2016 in Qidong. The AAPC of 5-ARSR in males and females were 2.63% (t=4.98, P=0.002) and 2.71% (t=6.08, P=0.001). There was statistically significant increase in 5-year ARSR among both genders. Furthermore, the AAPC of 5-year RSR among 25-34, 35-44, 45-54, 55-64, 65-74 and 75+ years old were 2.16% (t=4.28, P=0.004), 3.38% (t=5.06, P=0.001), 1.99% (t=2.82, P=0.026), 2.82% (t=3.39, P=0.012), 2.20% (t=2.82, P=0.026) and -0.91% (t=-0.42, P=0.689), respectively. Except for the 75+ years old age group, the other age groups were significantly upward trend. Conclusions: The overall survival rate of nasopharyngeal carcinoma in Qidong from 1972 to 2016 has shown an upward trend. It is necessary to introduce standardized multi-disciplinary treatment mode to improve treatment effect and survival rate.

Diagnosis and treatment procedures and health management for patients with hereditary angioedema / 中华预防医学杂志

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Preliminary insights into the practice of hypoallergenic home visiting program / 中华预防医学杂志

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.
