Objective To investigate and analysis the actuality and demands of scientific researchers in state clinical research facility of TCM, in order to provide evidences for policy making. Methods All the trainees taken part in the meeting for the training of clinical research method were assigned to answer the self-designed questionnaire. Results Of all these people, 47.58 percent people had senior professional title, 84.14 percent people had doctorate or master degree, 57.24 percent people had participated in project research at provincial or ministerial level as key personnel, 35.17 percent people had participated in a key disease research as directors, 65.52 percent people had taken methodology training of clinical research,30.34% of who trained by evidence-based medicine. The majority of these people had clear understanding in methodology of clinical research, who believed that evidence-based medicine and system evaluation are the most difficult subjects to understand and practice, hoping to learn more about the knowledge on statistics. Conclusion Clinical researchers of state clinical research facility of TCM had sound basis for scientific research, but relatively lacking of key disease research and systematic knowledge of scientific methodology, which needed to be enhanced.

Objective: To explore incidence trend of hepatitis C in Chifeng City, Inner Mongolia Autonomous Region from 2008 to 2022, so as to provide the basis for formulating prevention and control measures for hepatitis C. Methods: Data of reported hepatitis C cases in Chifeng City from 2008 to 2022 was collected through the Infectious Disease Information Reporting Management System. Trends in incidence of hepatitis C were analyzed using annual percent change (APC) and average annual percent change (AAPC). Impact of age, period and birth cohort on the risk of developing hepatitis C were analyzed by an age-period-cohort model. Results: The annual average reported incidence rate of hepatitis C in Chifeng City was 59.13/105 from 2008 to 2022. The incidence showed an upward trend from 2008 to 2018 (APC=9.405%, P<0.05) and a downward trend from 2018 to 2022 (APC=-17.475%, P<0.05), but the overall trend was not statistically significant (AAPC=0.937%, P>0.05). The age-period-cohort model analysis showed that the incidence risks of hepatitis C in the residents aged 0 to 4 years and 45 to 84 years were higher than those in the residents aged 40 to 44 years (the control group). The incidence risk of hepatitis C increased with age from 40 to 79 years. Compared with 2008-2012, the incidence risk of hepatitis C showed an increasing trend followed by a decline in 2008-2022. The incidence risk was higher in 2013-2017 and lower in 2018-2022 than in 2008-2012. The incidence risk of hepatitis C showed an increasing trend followed by a decreasing trend by using the birth cohort from 1968 to 1972 as the control. The birth cohort from 1953 to 1977 had a higher incidence risk of hepatitis C than other birth cohorts. Conclusions The overall incidence of hepatitis C in Chifeng City from 2008 to 2022 appeared a tendency towards a decline, and the incidence risk increased with age. Screening and health education for the elderly and high-risk birth cohorts should be strengthened.

Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.

The basic pathological change of diabetic macroangiopathy is atherosclerosis （AS）， which is mainly associated with vascular endothelial cells （VECs） injury， oxidative stress， glucose and lipid metabolism disorders， hemorheological abnormalities， and endoplasmic reticulum stress. The injury and dysfunction of VECs are the initiating factors of diabetic macroangiopathy. Autophagy is a subcellular self-protection mechanism that regulates basic intracellular metabolism through lysosome-mediated degradation of proteins and damaged organelles to maintain homeostasis. Insufficient autophagy of VECs leads to enhanced inflammation， apoptosis， and oxidative stress of VECs， which promotes AS. According to the theory of traditional Chinese medicine （TCM）， diabetic macroangiopathy corresponds to the syndrome of internal deficiency and pathogen invasion， with Qi deficiency and stagnation as the key pathogenesis. Qi deficiency is the root cause， and Qi stagnation is the manifestation. The disease occurs with the initial cause of nutrient-defense disharmony and instability of vessels， the main cause of the deficiency of kidney Qi and the lack of source for generation and transformation， the internal cause of Qi and blood loss in the viscera and the stagnation of Qi， blood， and fluid， and the superficial cause of the stagnation of pathological products and the damage of vessels. Autophagy is a microscopic manifestation of Qi， which has the function of dispelling pathogens and maintaining homeostasis. Insufficient autophagy of VECs leads to Qi deficiency and stagnation， and the gradual deficiency and heavy stagnation of Qi lead to insufficient autophagy， which form a vicious cycle. Modern research has demonstrated that regulating the autophagy of VECs is the main way to prevent and treat AS， and TCM can exert the therapeutic effect in a multi-target and multi-pathway manner. Therefore， based on the theory of Qi deficiency and stagnation， the method of tonifying deficiency of and removing stagnation can be adopted to select prescriptions for regulating the autophagy of VECs and treating AS， which can slow down the procession of diabetic macroangiopathy.

Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.
