Delirium is a common cause and complication of hospitalization in the elderly and is associated with higher risk of future dementia and progression of existing dementia, of which 70% is Alzheimer's disease (AD). AD and delirium, which are known to be aggravated by one another, represent significant societal challenges, especially in light of the absence of effective treatments. The intricate biological mechanisms have led to numerous clinical trial setbacks and likely contribute to the limited efficacy of existing therapeutics. Artificial intelligence (AI) presents a promising avenue for overcoming these hurdles by deploying algorithms to uncover hidden patterns across diverse data types. This review explores the pivotal role of AI in revolutionizing drug discovery for AD and delirium from target identification to the development of small molecule and protein-based therapies. Recent advances in deep learning, particularly in accurate protein structure prediction, are facilitating novel approaches to drug design and expediting the discovery pipeline for biological and small molecule therapeutics. This review concludes with an appraisal of current achievements and limitations, and touches on prospects for the use of AI in advancing drug discovery in AD and delirium, emphasizing its transformative potential in addressing these two and possibly other neurodegenerative conditions.

Objective To evaluate the effectiveness and safety of inferior oblique transposition combined with medial and lateral rectus surgery in the treatment of inferior oblique hyperfunction combined with V-type strabismus.Methods Thirty-nine patients with inferior oblique hyperfunction combined with V-type strabismus admitted to Jiaxing Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from November 2020 to September 2021 were selected as study objects,and were divided into combined operation group(n=28)and multiple operation group(n=11)according to different surgical programs.The visual acuity,eye position,cure rate of V sign,correction rate of inferior oblique hyperfunction,oculocardiac reflex,oculogastric reflex and complications were compared between two groups.Results One month after surgery,patients of two groups recovered the first eye position,and there were no statistical significances in the number of V sign cured and the number of inferior oblique hyperfunction corrected(P>0.05).Visual acuity returned to preoperative level in both groups.There were no significant differences in oculocardiac reflex and oculogastric reflex between two groups(P>0.05).There were no inflammatory reaction,massive subconjunctival hemorrhage,subcutaneous hematoma of eyelid,retrobulbar hemorrhage and other complications in two groups.Conclusion The effect of inferior oblique transposition combined with medial and lateral rectus surgery in the treatment of inferior oblique hyperfunction combined with V-type strabismus is not inferior to that of conventional divided operation,but it can reduce the number of operations and avoid the pain caused by the second operation,which is worthy of clinical application.

Objective To investigate the impact of anti-reflux modified duodenal exclusion surgery on glucose metabolism in rats with type 2 diabetes mellitus (T2DM), and to elucidate the role of the duodenum in maintaining glucose homeostasis. MethodsForty male Sprague-Dawley rats aged 5 weeks were fed a high-fat diet and induced with T2DM using low-dose streptozotocin. Thirty-six rats that met the T2DM model criteria were randomly divided into three groups: the simple duodenal exclusion surgery group (DE group), the anti-reflux modified duodenal exclusion group (MDE group), and the sham operation group (SO group), with 12 rats in each group. Gastroenterography was performed 4 weeks after surgery, and the body weight, fasting blood glucose levels, and serum glucagon-like peptide-1 (GLP-1) concentrations were measured before surgery and at 1, 2, 4, and 8 weeks post-surgery. Eight weeks post-surgery, the rats were euthanized, and a 1 cm segment of the biliopancreatic loop was collected from each group for pathological sectioning and HE staining to observe the intestinal mucosal villus length under an optical microscope. Results Gastroenterography showed that there was significant reflux of the contrast agent into the duodenal lumen in the DE group, while no reflux was observed in the MDE group. At one week post-surgery, the body weights of rats in all three groups significantly decreased compared to before surgery (P<0.05), and then the body weights of all groups increased over time, with no significant differences between the groups (P>0.05). Compared with the SO group, the fasting blood glucose levels in the MDE and DE groups significantly decreased at all time points post-surgery (P<0.05), while GLP-1 concentrations significantly increased (P<0.05). The fasting blood glucose levels in the MDE group were lower than those in the DE group at all time points post-surgery (P<0.05), but there were no significant differences in serum GLP-1 concentrations between the MDE and DE groups (P>0.05). Regarding intestinal mucosal morphology, the villus lengths of the biliopancreatic loops in the MDE group were significantly shorter than those in the DE and SO groups (P<0.05). Conclusion Anti-reflux modified duodenal exclusion surgery effectively improves glucose metabolism in T2DM rats by preventing the reflux of chyme into the diverted duodenum, thereby enhancing its hypoglycemic effect.

"Let food be thy medicine and medicine be thy food"-the ancient adage proposed by Greek philosopher Hippocrates of Kos thousands of years ago already acknowledged the importance of the beneficial and health-promoting effects of food nutrients on the body (Mafra et al., 2021). Recent epidemiological and large-scale community studies have also reported that unhealthy diets or eating habits may contribute heavily to the burden of chronic, non-communicable diseases, such as obesity, type 2 diabetes mellitus (T2DM), hypertension, cardiovascular disease (CVD), cancer, neurodegenerative diseases, arthritis, chronic kidney disease (CKD), and chronic obstructive pulmonary disease (COPD) (Jayedi et al., 2020; Gao et al., 2022). Emerging evidence highlights that a diet rich in fruits and vegetables can prevent various chronic diseases (Chen et al., 2022). Food bioactive compounds including vitamins, phytochemicals, and dietary fibers are responsible for these nutraceutical benefits (Boeing et al., 2012). Recently, phytochemicals such as polyphenols, phytosterols, and carotenoids have gained increasing attention due to their potential health benefits to alleviate chronic diseases (van Breda and de Kok, 2018). Understanding the role of phytochemicals in health promotion and preventing chronic diseases can inform dietary recommendations and the development of functional foods. Therefore, it is crucial to investigate the health benefits of phytochemicals derived from commonly consumed foods for the prevention and management of chronic diseases.

Objective:To investigate the efficacy and safety of retroperitoneal soft tissue sarcoma resection combined with nephrectomy.Methods:The clinical data of 27 cases undergoing retroperitoneal soft tissue sarcoma resection combined with nephrectomy at the Gastrointestinal Tumor Center , Guangdong Provincial Hospital , Traditional Chinese Medicine from Jun 2017 to Aug 2022 were retrospectively analyzed for the indication of nephrectomy, postoperative progression of renal insufficiency and survival rate.Results:Twenty-six cases (96%) achieved R 0/R 1 resection and 1 case nderwent R 2 resection. Six cases underwent combined unilateral nephrectomy and 21 patients underwent combined multi-organ resection with a median number of resections of 4 (2,5). Postoperative pathology suggested that the combined resected kidney was positive for tumor infiltration in 17 cases. Five cases had Clavien-Dindo grade 3 or higher complications and no deaths occurred within 30 days after surgery. At the 90th day after surgery, 19 cases (70%) had decreased renal function ( Z=2.88, P=0.04), with a median decrease of -3.96 (-30.36, 0.31)ml·(min·1.73 m 2) -1, including 8 cases of preoperative Chronic Kidney Disease(CKD)1 stage progression (6 cases of CKD 2 stage, 2 cases of CKD 3 stage); 2 cases of CKD 2 stage progressed to CKD 3 stage; 1 case of preoperative CKD 3 stage progressed to CKD 4 stage. During the follow-up period of 3-38 months, no patient progressed to CKD 5 stage and no patient required dialysis treatment. Conclusion:Retroperitoneal soft tissue sarcoma resection combined with nephrectomy is safe and feasible while improving tumor radicality.

Objective:To investigate the feasibility of reducing the radiation dose on coronary artery calcium score (CS) of virtual non-contrast (VNC) scanning in dual-layer spectral coronary CT angiography(CCTA).Methods:One hundred and twenty-two patients were examined on a dual-layer spectral detector CT scanner from March 2019 to August 2020. Volume CT dose index (CTDI vol), dose length product (DLP), effective dose ( E) were all evaluated for each patient. CS was calculated from both true non-contrast (TNC) and VNC images for left anterior descending (LAD), left circumflex (LCx), right coronary artery (RCA), and the total coronary artery (Total) by two radiologists independently. Pearson′s correlation coefficient was calculated for measuring the association between variables. The correction coefficients of each branch (λ LAD, λ LCx, and λ RCA) and the average correction coefficient (λ AVG) of the total coronary artery were obtained. The calibrated calcium score (CCS_VNC) was equal to λ multiplied by CS_VNC. The CS_TNC and CCS_VNC were compared using repeated oneway analysis of variance test. Correlation analyses for CS_TNC and CCS_VNC and agreement evaluation with Bland-Altman-Plots were performed. Results:The average effective doses in TNC, CCTA and total group were 0.69, 6.47 and 7.16 mSv, respectively. The effective dose was reduced by 10.6% and the scan time was reduced by 39% while using VNC images. There were significant differences among the CS_TNC and CS_VNC of LAD, LCx, RCA and Total ( t=6.75, 5.33, 4.99, 6.60, P< 0.05). Excellent correlations were observed between CS_VNC and CS_TNC ( R2 values were 0.929, 0.896, 0.958, and 0.918; λ values were 2.18, 1.18, 2.15, and 2.07, respectively). There were no significant statistically difference among the CS_TNC, CCS_VNC AVG, and CCS_VNC LAD/RCA of the LAD and RCA (all P> 0.05). The difference was statistically significant among the CS_TNC, CCS_VNC AVG, and CCS_VNC LCx of the LCx ( F=10.94, P<0.05). The paired comparison were performed in groups and the differences were statistically significant between the CS_TNC versus CCS_VNC AVGand CCS_VNC AVG versus CCS_VNC LCx ( t=3.31, 3.43, all P<0.05). There was no significant statistically difference between the CCS_VNC LCx and CCS_VNC AVG( P>0.05). Conclusions:It was feasible to accurately evaluate the CS_VNC from spectral data in comparison to TNC imaging, and to reduce the patient radiation dose and acquisition time.

Objective:To simulate the effects of different thyroid-neck phantoms and monitoring positions on the detection efficiency of portable γ spectrometer, and to provide guidance for more accurate on-site measurement of 131I activity in the human thyroid. Methods:Based on the models of 4 typical thyroid-neck phantoms and a 3-inch NaI (TI) γ spectrometer used for the measurement of 131I in the thyroid and combined with the possible field monitoring scenarios, the Monte Carlo method was used to simulate and calculate the detection efficiency of the spectrometer under different conditions of monitoring distance, thyroid depth and thyroid volume. Results:The detection efficiency decreased significantly with the increase in the distance between the detector and the neck surface. The efficiency close to the neck surface was about 15 times that at 15 cm away from the neck surface. The detection efficiency decreased significantly with the increase in thyroid depth. When it was measured at the surface of the neck, the detection efficiency of thyroid at depth of 2 mm was about 3.6 times that of 30 mm. The detection efficiency decreases with the increase in thyroid volume. When it was measured at the neck surface, the detection efficiency of thyroid with 1 ml volume was 1.71 times that with 30 ml. The detection efficiency decreased with the center-point offset of the detector, especially at the neck surface, an offset of 2 cm would reduce the detection efficiency by about 15%.Conclusions:Not only the measurement distance used in calibration, but also the information of the depth and volume of thyroid in the neck-thyroid phantom, is important to know in advance for an accurate measurement of 131I activity in thyroid by using a portable gamma spectrometer.

Objective    To evaluate the effectiveness and safety of a central venous catheter for thoracic drainage after video-assisted thoracoscopic lobectomy compared with a conventional chest tube. Methods    This study collected 200 patients with lung cancer who underwent thoracoscopic lobectomy and systematic hilar and mediastinal lymph node dissection between January 2018 and September 2019 in our hospital. The patients were randomly divided into two groups, including a group A (left with 28F chest tubes postoperatively) and a group B (left with 12G central venous catheters postoperatively). Patients in both groups were left with 2 chest tubes after upper lobectomy and 1 chest tube after middle or lower lobectomy. Duration and total volume of drainage, length of hospital stay, maximum visual analogue scale score and so forth were compared between the two groups. Results    Finally, 151 patients were included for analysis. There were 73 patients in the group A, including 26 males and 47 females, with an average age of 55.38±9.95 years, and 78 patients in the group B, including 37 males and 41 females, with an average age of 59.86±10.18 years. No statistical  difference was found between the two groups in drainage volume on postoperative day 2, and proportion of prolonged air leaks, hemothorax, chylothorax or drain reinsertion (all P>0.05). There was a statistical difference in drainage volume on postoperative day 1 [200.0 (120.0, 280.0) mL vs. 57.5 (10.0, 157.5) mL, P=0.000], postoperative day 3 [155.0 (100.0, 210.0) mL vs. 150.0 (80.0, 215.0) mL, P=0.023], total volume of drainage [890.0 (597.5, 1 530.0) mL vs. 512.5 (302.5, 786.3) mL, P=0.000], maximum pain score (2.29±0.72 points vs. 2.09±0.51 points, P=0.013) and length of hospital stay [7 (7, 9) d vs. 5 (4, 7) d, P=0.000]. Conclusion    Compared with conventional chest tubes, central venous catheters for chest drainage in patients with lung cancer after thoracoscopic lobectomy shortens the length of hospital stay and reduces postoperative pain.
