In the context of the modernization of traditional Chinese medicine （TCM）， the inheritance of the experiences of famous doctors faces significant challenges due to its complex nonlinear characteristics and dynamic evolution. There are still issues in the current inheritance system， such as the homogenization of talent cultivation models， lack of standardized mentoring practices， and monotonous evaluation method， which hinder the systematic inheritance and innovative development of famous doctors' experiences. Based on a systematic review of the current state of artificial intelligence （AI）-assisted inheritance of famous doctors' experiences， this study explores innovative pathways for deep integration of modern information technologies with famous doctors' experiences from key dimensions， including data authenticity assurance， interdisciplinary collaboration mechanisms， and the establishment of dynamic inheritance standards. It proposes a paradigm shift in the inheritance of TCM famous doctors' experiences in the AI era， aiming to build a new TCM inheritance system of "digital intelligence empowerment and cross-disciplinary innovation"， providing theoretical support and practical pathways for the inheritance of famous doctors' experiences in TCM.

Objective: To analyze the trend in burden of rheumatoid arthritis (RA) in China from 1990 to 2021, so as to provide insights into reducing the RA burden in China. Methods: Data of Global Burden of Disease Study 2021 were collected, and the incidence, mortality and disability-adjusted life years (DALY) of RA in China from 1990 to 2021 were analyzed and compared with global and different Socio-demographic Index (SDI) regions. The trend in burden of RA was analyzed using average annual percent change (AAPC). Results: The crude incidence rates of RA in China increased from 10.87/105 in 1990 to 17.38/105 in 2021, the crude mortality rates increased from 0.41/105 to 0.72/105, and the crude DALY rates increased from 34.26/105 to 58.61/105, with the increases of 59.98%, 77.95% and 71.06%, respectively. From 1990 to 2021, the standardized incidence rates of RA in China showed an increasing trend (AAPC=0.545%, P<0.05), the standardized mortality rates showed a decreasing trend (AAPC=-0.783%, P<0.05), and the standardized DALY rates showed no significant trend (AAPC=-0.017%, P>0.05). In 2021, the standardized incidence rate, standardized mortality rate and standardized DALY rate of RA were higher in females than in males; from 1990 to 2021, the standardized DALY rates of RA showed a decreasing trend in females (AAPC=-0.200%, P<0.05) and an increasing trend in males (AAPC=0.316%, P<0.05). The crude incidence rates of RA first increased and then decreased with age in 2021, reaching the highest in the age group of 75-<80 years at 34.36/105. Both the crude mortality rates and the crude DALY rates increased with age, reaching the highest in the age group of 95 years and older at 26.72/105 and 285.67/105, respectively. The standardized incidence rates and standardized DALY rates of RA in China in 2021 were lower than those in high SDI regions, while the standardized mortality rate was lower than that in medium-low SDI regions. Conclusions The burden of RA in China from 1990 to 2021 showed an upward trend, and was at a high level compared to different SDI regions. Higher disease burden of RA was seen in females and the elderly.

Ying and wei qi is derived from the essence of water and grain， and is the basic material to maintain the normal life activities of the body. Ying and wei qi has the difference of nature of yin and yang or the clear and the turbid. When the relationship between ying and wei qi is out of order and in reverse disorder， it will lead to the occurrence of various diseases. Based on the analysis of the theory of "ying-wei disorder" in The Inner Canon of Yellow Emperor （《黄帝内经》）， this paper started from the perspective of the exuberance and debilitation， circulation and function of ying qi and wei qi， focused on the theoretical understanding that the change of deficiency and excess （"fall"） and the change of circulation （"move"）， and refined the core mechanism of "ying-wei disorder"， which is the depletion of ying qi and wei qi， stagnation of ying qi and wei qi， and disharmony of ying qi and wei qi， and finally summarized the syndrome identification and treatment method of supporting ying qi and assisting wei qi， promoting ying qi and moving wei qi， regulating ying qi and wei qi， and constructed the syndrome identification and treatment system for ying-wei disorder of malignant tumor in clinic.

Objective To design a multisensory supported device and evaluate its effectiveness on preterm infants(born before 34 weeks)during NICU hospitalization.Methods The multisensory supported device is composed of a basement,several soft cushions and an adjustable eye mask.The inner layer of the device comprises of the head and tail boundaries,serves as uterine wall-like circular boundaries.The outer skeleton is equipped with multisensory stimulation modules to provide visual,hearing,and tactile sensory stimulations for premature infants.The study was conducted in a NICU of a tertiary A children specialist hospital in Shanghai,China.The convenience sampling method was used and based on the ratio of 1∶2 between the experimental and the control group in this study.The control group was treated by standard nursing care,while the experiment group was treated with the multisensory supported device in addition to NICU conventional care.All infants were assessed during the week of admission and again at corrected gestational age of 36 weeks.The actigraphy watch which was used for 72 hours continuous record of the activities of study infants,allows the researcher to compare the activity scores,wakefulness and sleep indicators of 2 groups of infants.Results 71 preterm infants were enrolled in the study,and 60 preterm infants completed data collection for study data analysis,including 20 in the experimental group and 40 in the control group.There were no statistical differences in demographic characteristics and clinical status regarding wakefulness,sleep and physical development between the 2 groups in baseline(P＞0.05).At 36 weeks of corrected gestational age,the activity score of the experimental group was(46.61±12.14)points,and that of the control group was(57.33±18.36)points,with statistically significant differences in 2 groups(P=0.024).The total waking time of the experimental group was(384.85±169.42)min,and that of the control group was(492.08±220.45)min,with statistically significant differences in 2 groups(P=0.049).There was no statistical difference in other indicators between 2 groups(P＞0.05).Conclusion The multisensory supported device can reduce high-frequency unpleasant activity as well as frequent wakefulness status,which could promote the sleeping quality of preterm infants.Further studies are needed to verify further effects of the device on premature infants'physical development.

Objective:To explore the normal ranges of perfusion parameters between cerebral hemisphere, cerebellar hemisphere and brain anatomical subregions (56 pairs) in different gender and age groups with multiple post labeling delay time (Multi-PLD) arterial spin labeling (ASL) imaging.Methods:From November 2020 to December 2020, 42 healthy adult volunteers (Male 25, Female 17) were recruited to perform 7 PLD ASL imaging, including 21 young adults (15 males and 6 females, aged 23—35 years) and 21 seniors (10 males and 11 females, aged 36—74 years). The data was processed offline by Cereflow software to obtain arterial arrival time (ATT) and corrected cerebral blood flow (CBF) and cerebral blood volume (CBV) perfusion parameters. SimpleITK standardization function was used to standardize the calculated perfusion image according to the anatomical automatic labeling (AAL) template. Therefore, CBF, ATT, CBV perfusion values of brain subregions were obtained. Paired samples t test, Wilcoxon rank sum test, independent samples t test and Mann-Whitney U test were used to compare the differences of perfusion parameters in the cerebral hemisphere, the cerebellar hemisphere, brain subregions depending on side, gender and age. Pearson correlation analysis was used to compare the correlations of perfusion parameters with age. Results:CBF in 62.5% (35/56) subregions and CBV in 44.6% (25/56) subregions were higher in right side than those in left side. ATT in most brain anatomical subregions (16/56) were higher in left side. The CBF [(35.30±8.31) vs. (34.34±7.53) ml·100g -1·min -1, P=0.021], CBV [(0.47±0.11) vs. (0.45±0.09) ml/100g, P<0.001], ATT [(1.30±0.10) vs. (1.24±0.11) s, P<0.001] in left cerebellar hemisphere were higher than that of right side. The CBF (28/56) of cerebral hemisphere, cerebellar hemisphere and brain subregions was higher in females than that in males, while ATT in 83.9% (47/56) subregions was lower than that in males (all P<0.05). CBV in female subjects was higher only in 5 brain regions (superior occipital gyrus, middle occipital gyrus, inferior occipital gyrus, superior parietal gyrus and cerebelum_7b) (all P<0.05). In young subjects, CBF in 44.6% (25/56) subregions and CBV in 33.9% (19/56) subregions were higher than those in the senior group (all P<0.05). The ATT in most subregions in young group were lower than those in senior group, but the difference was statistically significant only in rectus gyrus ( P=0.026) and paracentral lobule ( P=0.006). The CBF ( r=-0.430, P=0.005) and CBV ( r=-0.327, P=0.035) of cerebral hemisphere were negatively correlated with age. The CBF (24/25, r range:-0.497 —-0.343, all P<0.05) and CBV (16/19, r range:-0.474 —-0.322, all P<0.05) in most subregions were negatively correlated with age, while ATT was positively correlated (gyrus rectus: r=0.311, P=0.045; paracentral lobule: r=0.392, P=0.010). Conclusions:Multi-PLD ASL imaging could be applied for quantitative analysis of brain perfusion. The perfusion parameters of anatomical subregions are different depending on side, gender, and age.

Objective:To investigate the changes of proopiomelanocortin(POMC) expression in hypothalamus and corresponding metabolism in miR-21 knockout mice.Methods:miR-21 knockout or wild-type C57BL/6J mice were divided into diabetic group and control group, respectively. Diabetic mice model were forged with high-fat diet and low-dose streptozotocin. The changes of body weight and blood glucose in each group were monitored. By the end of the experiment, mice were sacrificed, and POMC protein expression and STAT3 mRNA expression in hypothalamus were detected.Results:There were no significant differences in body weight and blood glucose levels among all groups at baseline( P>0.05). The differences of body weight and blood glucose levels among various groups were compared at 3, 6, 9 and 12 weeks after the model was established. The results showed that body weight of mice in the diabetes group or miR-21 knockout+ diabetes group was higher than that in the control group at each time point( P<0.05). Moreover, there were significant difference in body weight between diabetes group and miR-21 knockout+ diabetes group at 3 and 12 weeks( P<0.05). The blood glucose levels in diabetes group were significantly higher than those in other groups at each time point( P<0.05). The blood glucose level in miR-21 knockout+ diabetes group was lower than that in diabetes group and higher than control group( P<0.05). POMC protein and STAT3 mRNA levels in diabetes group were significantly lower than those in control group, while those in the miR-21 knockout+ diabetes group were higher than those in the diabetes group. Conclusions:The expression of POMC in hypothalamus of miR-21 knockout mice is higher than that of wild-type diabetic mice. miR-21 knockout can decrease blood glucose level and body weight, and improve energy metabolism of diabetic mice.

As an important promising biomarker, high frequency oscillations (HFOs) can be used to track epileptic activity and localize epileptogenic zones. However, visual marking of HFOs from a large amount of intracranial electroencephalogram (iEEG) data requires a great deal of time and effort from researchers, and is also very dependent on visual features and easily influenced by subjective factors. Therefore, we proposed an automatic epileptic HFO detection method based on visual features and non-intuitive multi-domain features. To eliminate the interference of continuous oscillatory activity in detected sporadic short HFO events, the iEEG signals adjacent to the detected events were set as the neighboring environmental range while the number of oscillations and the peak–valley differences were calculated as the environmental reference features. The proposed method was developed as a MatLab-based HFO detector to automatically detect HFOs in multi-channel, long-distance iEEG signals. The performance of our detector was evaluated on iEEG recordings from epileptic mice and patients with intractable epilepsy. More than 90% of the HFO events detected by this method were confirmed by experts, while the average missed-detection rate was < 10%. Compared with recent related research, the proposed method achieved a synchronous improvement of sensitivity and specificity, and a balance between low false-alarm rate and high detection rate. Detection results demonstrated that the proposed method performs well in sensitivity, specificity, and precision. As an auxiliary tool, our detector can greatly improve the efficiency of clinical experts in inspecting HFO events during the diagnosis and treatment of epilepsy.

This study was aimed to observe the therapeutic effect of qi-supplementing,blood-activating and phlegmresolving on chronic obstructive pulmonary disease (COPD) patients with blood stasis syndrome in the acute stage,and to evaluate the lung function improvement condition.Observation was also made on plasma fibrinogen and D-dimer,in order to provide references for traditional Chinese medicine (TCM) clinical treatment of COPD.A total of 174 acute COPD patients with blood stasis syndrome were selected from October 2015 to July 2017 in the Linqu County People's Hospital of Shandong Province.Patients were randomly divided into the control group and the study group.Conventional western medicine treatment was given to the control group.On the basis of routine western medicine treatment,the study group was treated with TCM qi-supplementing,blood-activating and phlegm-resolving method.The clinical efficacy,changes of lung function,plasma fibrinogen and D-dimer before and after treatment were observed in both groups.The results showed that the total efficacy of the study group was 95.4％,and the total efficacy of the control group was 79.3％.The difference was statistically significant (P ＜ 0.05).Pearson correlation study showed that plasma fibrinogen (r =-0.79,P ＜ 0.05) and D-dimer (r =-0.84,P ＜ 0.05) were negatively correlated with PaO2.Before treatment,there was no significant difference in lung function,plasma fibrinogen and D-dimer between two groups (P ＞ 0.05).After treatment,indicators of both groups were significantly improved,in which the improvement of the study group was more obvious.The difference between two groups was statistically significant (P ＜ 0.05).It was concluded that the expression levels of plasma fibrinogen and D-dimer were closely related to COPD.Qi-supplementing,blood-activating and phlegmresolving method can improve clinical symptoms,blood stasis status and lung function of COPD patients in the acute stage with remarkable curative effect.
