Abstract
BACKGROUND Healthy diet is essential for cardiovascular disease risk management, but its effects among Chinese patients, whose diets differ from Western diets, remain largely unknown. METHODS In this multicenter, patient- and outcome assessor-blind, randomized controlled feeding trial, 265 Chinese adults with baseline systolic blood pressure 130 to 159 mmHg were randomly assigned into Chinese heart-healthy (CHH) diet or usual diet for a 28-d intervention after a 7-d run-in period on usual diet. Blood lipids and glucose were measured from overnight fasting blood samples before and after the intervention. Ten-year cardiovascular disease risk was estimated using models previously developed and validated in Chinese. The changes in secondary outcomes of serum total cholesterol (TC), blood glucose, and 10-y cardiovascular disease risk over the intervention period were compared between intervention groups, adjusting for center, among participants with baseline and follow-up blood samples available. Sensitivity analyses were done with further adjustment for baseline values and covariables; missing data imputed; and among per-protocol population. RESULTS Among 256 eligible participants (130 on CHH diet, 126 on control diet), 42% had hypercholesterolemia and 15% had diabetes at baseline. In the control group, TC and 10-y cardiovascular disease risk decreased after the intervention by 0.16 mmol/L and 0.91%, respectively, but blood glucose increased by 0.25 mmol/L. Compared with usual diet, the CHH diet lowered TC (-0.14 mmol/L, P = 0.017) and 10-y cardiovascular disease risk (-1.24%, P = 0.001) further. No effect on blood glucose was found. All sensitivity analyses confirmed the results on TC and 10-y cardiovascular disease risk, and analysis with multiple variables adjusted showed a borderline significant effect on blood glucose (-0.17 mmol/L, P = 0.051). The differences in intake of nutrients and food groups between intervention groups explained the results. CONCLUSIONS The CHH diet reduced TC and 10-y cardiovascular disease risk and was likely to reduce blood glucose among Chinese adults with mild hypertension. Further studies with longer terms are warranted. This trial was registered at clinicaltrials.gov as NCT03882645.

Abstract
OBJECTIVE To determine whether the Chinese heart-healthy diet (Sichuan cuisine version) (CHH diet-SC) was more expensive than the conventional Sichuan diet and explore the food groups and nutrients that mainly affected the cost of CHH diet-SC. DESIGN Cost analysis of 4-week intervention diets in the Sichuan center representing southwestern China in the CHH diet study. SETTING A multicentre, parallel-group, single-blind, randomised feeding trial evaluating the efficacy of lowering blood pressure with the cuisine-based CHH diet. PARTICIPANTS Totally, fifty-three participants with hypertension aged 25-75 years in the Sichuan center were randomised into the control group (n 26) or the CHH diet-SC group (n 27). RESULTS The CHH diet-SC was more expensive than the control diet (¥27·87 ± 2·41 v. ¥25·18 ± 2·79 equals $3·90 ± 0·34 v. $3·52 ± 0·39, P < 0·001), and the incremental cost-effectiveness ratio for a 1-mm Hg systolic blood pressure reduction was ¥9·12 ($1·28). Intakes and the cost of seafood, dairy products, fruits, soybeans and nuts, whole grains and mixed beans were higher for the CHH diet-SC than for the control diet (P < 0·001). Intakes of vitamin B1, vitamin B6, vitamin C, Mg and phosphorus were positively correlated with the cost (P < 0·05). CONCLUSIONS The CHH diet-SC costs more than the conventional Sichuan diet, partly due to the high cost of specific food groups. Positive correlations between the intakes of vitamin B1, vitamin B6, vitamin C, Mg, phosphorus and the dietary cost could be a direction to adjust the composition within the food groups to reduce the cost of the CHH diet-SC.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) is characterized by reproductive dysfunctions and metabolic disorders. This study aims to compare the therapeutic effectiveness of glucagon-like peptide-1 receptor agonist (GLP-1RA) + Metformin (Met) versus cyproterone acetate/ethinylestradiol (CPA/EE) + Met in overweight PCOS women and identify potential proteomic biomarkers of disease risk in women with PCOS. METHODS In this prospective, open-label randomized controlled trial, we recruited 60 overweight PCOS women into two groups at a 1:1 ratio to receive CPA/EE (2 mg/day: 2 mg cyproterone acetate and 35-μg ethinylestradiol,) +Met (1500 mg/day) or GLP-1 RA (liraglutide, 1.2-1.8 mg/day) +Met (1500 mg/day) for 12 weeks. The clinical effectiveness and adverse effects were evaluated, followed by plasma proteomic analysis and verification of critical biomarkers by ELISA. RESULTS Eighty(80%) patients completed the study. Both interventions improved menstrual cycle, polycystic ovaries, LH(luteinizing hormone) and HbA1c(hemoglobin A1c) levels after the 12-week treatment. GLP-1RA + Met was more effective than CPA/EE + Met in reducing body weight, BMI (Body Mass Index), and waist circumference, FBG(fasting blood glucose), AUCI(area under curve of insulin),TC (Total Cholesterol), IL-6(Interleukin-6) and improving insulin sensitivity, and ovulation in overweight women with PCOS, with acceptable short-term side effects. CPA/EE + Met was more effective in improving hyperandrogenemia, including T(total testosterone), LH, LH/FSH(Luteinizing hormone/follicle-stimulating hormone), SHBG(sex hormone-binding globulin) and FAI (free androgen index). By contract, GLP-1RA+Met group only improved LH. Plasma proteomic analysis revealed that the interventions altered proteins involved in reactive oxygen species detoxification (PRDX6, GSTO1, GSTP1, GSTM2), platelet degranulation (FN1), and the immune response (SERPINB9). CONCLUSIONS Both CPA/EE+Met and GLP-1RA + Met treatment improved reproductive functions in overweight PCOS women. GLP-1RA + Met was more effective than CPA/EE + Met in reducing body weight, BMI, and waist, and improving metabolism, and ovulation in overweight women with PCOS, with acceptable short-term side effects. CPA/EE + Met was more effective in reducing hyperandrogenemia. The novel plasma biomarkers PRDX6, FN1, and SERPINB9, might be indicators and targets for PCOS treatment.

Abstract
INTRODUCTION Anemia of chronic kidney disease (CKD) has a high incidence and is associated with many disease conditions. Iron dysmetabolism is an important contributor to anemia in CKD patients. METHODS ALTAI, a randomized, active-controlled, phase 4 trial, investigated the efficacy of roxadustat versus recombinant human erythropoietin (rHuEPO) on gastrointestinal iron absorption in patients with anemia of CKD (stage 4/5). The primary endpoint was change from baseline to day 15 in gastrointestinal iron absorption (serum iron area under the concentration-time curve; AUC0-3h) following single-dose oral iron. RESULTS Twenty-five patients with a mean age of 55.1 years were randomized 1:1 to roxadustat (n = 13) or rHuEPO (n = 12). Baseline iron profiles were similar between treatment groups. Change from baseline to day 15 in serum iron AUC0-3h was not statistically significantly different between the roxadustat and rHuEPO groups. Mean (SD) change from baseline in serum iron AUC0-3h was 11.3 (28.2) g × 3 h/dl in the roxadustat group and - 0.3 (9.7) g × 3 h/dl in the rHuEPO group. Roxadustat treatment was associated with decreased hepcidin and also increased transferrin, soluble transferrin receptor, and total iron-binding capacity (TIBC), with nominal significance. The proportion of patients experiencing one or more adverse events was 38.5% when treated with roxadustat and 16.7% with rHuEPO. CONCLUSIONS The study showed no significant difference between roxadustat and rHuEPO in iron absorption but was underpowered because of recruitment challenges.

Abstract
OBJECTIVE This study aimed to evaluate the effects of three antioxidants, selenium yeast capsule, vitamin E and vitamin C, alone or in combination, on the salivary glands of patients with differentiated thyroid cancer (DTC) treated with iodine-131 ( 131 I). METHODS A total of 69 postoperative DTC patients were randomly divided into three groups: vitamin E combined with vitamin C group (21 cases); selenium yeast group (23 cases); and selenium yeast combined with vitamin C group (25 cases). Salivary gland functional changes were assessed by salivary gland dynamic imaging functional parameters in the enrolled patients before and 1 month after 131 I treatment. RESULTS Comparison of salivary gland function parameters before and after 131 I treatment in the three groups were evaluated. In the vitamin E combined with the vitamin C group, the left parotid gland excretion fraction (EF) value was significantly higher than that before treatment. In the selenium yeast group, the left parotid gland excretion part, bilateral parotid gland excretion ratio (ER), left submandibular gland maximum uptake ratio within 20 min (UR20), and the right submandibular gland ER values were significantly higher than that before treatment, while in the selenium yeast combined with vitamin C group, the bilateral parotid gland EF, bilateral submandibular gland UR20, EF, and left submandibular gland ER values were significantly higher than that before treatment (all P < 0.05). CONCLUSION During high-dose 131 I treatment, vitamin E combined with vitamin C improved the excretory function of parotid glands in DTC patients; selenium supplementation had a protective effect on salivary glands; and the combination of selenium and vitamin C had a better effect.

Abstract
OBJECTIVE To study the effect of parecoxib sodium on tumor microenvironment in patients undergoing laparoscopic radical resection of rectal cancer. METHODS Sixty patients undergoing laparoscopic surgery for radical rectal cancer resection were randomized into test group and control group (n=30). The patients in test control group received intravenous injections of 40 mg parecoxib sodium at the time of anesthesia induction, immediately after and at 12 h after the surgery, and those in the control group were injected with an equal volume of physiological saline at the same time points. Plasma levels of IL-6, TNF-α, and CXCL8 of the patients were measured using ELISA, and expressions of CXCL8, CXCR1, and CXCR2 in the peripheral blood mononuclear cells (PBMCs) were detected with Western blotting. Postoperative VAS scores and gastrointestinal reactions and disease regression at 6 months after the operation were recorded. RESULTS Compared with the control patients, the patients in the test group showed significantly reduced plasma levels of IL-6, TNF-α, and CXCL8 (P < 0.05) and milder elevations of CXCL8, CXCR1, and CXCR2 proteins in PBMCs (P < 0.05) with significantly lower VAS scores at 12 h and 24 h after the operation (P < 0.05) and lower postoperative incidence of adverse gastrointestinal reactions (P < 0.05). At 6 months after the operation, the number of patients with metastasis or tumor recurrence was significantly smaller in the test group than in the control group (P>0.05). CONCLUSION Parecoxib sodium can improve the inflammatory microenvironment to promote patient recovery after laparoscopic radical resection of rectal cancer possibly through a mechanism that down-regulates CXCL8-CXCR1/2 expressions in the PBMCs.

Abstract
BACKGROUND AND OBJECTIVES To explore the risk factors for non-alcoholic fatty liver disease (NAFLD) and to establish a non-invasive tool for the screening of NAFLD in an older adult population. METHODS AND STUDY DESIGN A total of 131,161 participants were included in this cross-sectional study. Participants were randomly divided into training and validation sets (7:3). The least absolute shrinkage and selection operator method was used to screen risk factors. Multivariate logistic regression was employed to develop a nomogram, which was made available online. Receiver operating characteristic curve analysis, calibration plots, and decision curve analysis were used to validate the discrimination, calibration, and clinical practicability of the nomogram. Sex and age subgroup analyses were conducted to further validate the reliability of the model. RESULTS Nine variables were identified for inclusion in the nomogram (age, sex, waist circumference, body mass index, exercise frequency, systolic blood pressure, fasting plasma glucose, alanine aminotransferase, and low-density lipoprotein cholesterol). The area under the receiver operating characteristic curve values were 0.793 and 0.790 for the training set and the validation set, respectively. The calibration plots and decision curve analyses showed good calibration and clinical utility. Subgroup analyses demonstrated consistent discriminatory ability in different sex and age subgroups. CONCLUSIONS This study established and validated a new nomogram model for evaluating the risk of NAFLD among older adults. The nomogram had good discriminatory performance and is a non-invasive and convenient tool for the screening of NAFLD in older adults.

Acta paediatrica (Oslo, Norway : 1992). 2023;(6):1333-1340
Abstract
AIM: The aim of the study was to develop a deep convolutional neural networks (CNNs) algorithm for automated assessment of stool consistency from diaper photographs and test its performance under real-world conditions. METHODS Diaper photographs were enrolled via a mobile phone application. The stool consistency was assessed independently according to the Brussels Infant and Toddler Stool Scale (BITSS) by paediatricians. These images were randomised into a training data set and a test data set. After training and testing, the new algorithm was used under real-world conditions by parents. RESULTS There was an overall agreement of 92.9% between paediatricians and the CNN-generated algorithm. Post hoc classification into the validated 4 categories of the BITSS yielded an agreement of 95.4%. Spearman correlation analysis across the ranking of 7 BITSS photographs and validated 4 categories showed a significant correlation of rho = 0.93 (95% CI, 0.92, 0.94; p < 0.001) and rho = 0.92 (95% CI, 0.90, 0.93; p < 0.001), respectively. The real-world application yielded further insights into changes in stool consistency between age categories and mode of feeding. CONCLUSION The new CNN-based algorithm is able to reliably identify stool consistency from diaper photographs and may support the communication between parents and paediatricians.

Abstract
AIM: To evaluate the efficacy and safety of empagliflozin in combination with insulin ± oral antidiabetic drugs (OADs) over 24 weeks, in Chinese patients with type 2 diabetes (T2D) who had insufficient glycaemic control. MATERIALS AND METHODS This was a randomized, double-blind, placebo-controlled, parallel group, multicentre phase III study. Adult patients with T2D and insufficient glycaemic control who received insulin ± up to two OADs were randomized (1:1:1) to receive empagliflozin 10 or 25 mg, or placebo for 24 weeks. The primary endpoint was change from baseline in HbA1c at week 24. RESULTS Of 219 randomized patients, 73 patients were in each treatment group; baseline characteristics were comparable among the groups. There was a significantly larger decrease from baseline in HbA1c (adjusted mean treatment difference -0.99 and -0.98 for in the empagliflozin 10 and 25 mg groups, respectively; P < .0001) with both doses of empagliflozin than with placebo. There were also significantly larger decreases from baseline in fasting plasma glucose, 2-hour postprandial glucose and body weight with both empagliflozin doses than with placebo. Among patients in the empagliflozin 10 mg, 25 mg and placebo groups, 17.8%, 9.6% and 11.0% reported confirmed hypoglycaemic events, respectively (nominal P = .2422 and .7661 in the empagliflozin 10 and 25 mg groups, respectively), and no Clinical Events Committee-confirmed diabetic ketoacidosis events were reported. CONCLUSIONS In Chinese patients with T2D, empagliflozin combined with insulin ± OADs improved glycaemic control and was well tolerated, without an increased risk of hypoglycaemia.

BMC medicine. 2023;(1):459
Abstract
BACKGROUND AD16 is a Class 1.1 new drug candidate for Alzheimer's disease (AD), which has demonstrated potential benefits in AD by reducing neuroinflammation in preclinical studies. Herein, the pharmacokinetics (PK), safety, and tolerability of single and multiple-dose AD16 and the effect of food were assessed in healthy Chinese adults. METHODS Single-center, randomized, placebo-controlled, double-blind studies were conducted for single and multiple ascending doses. A total of 62 subjects were enrolled in single-dose groups; 10 each in 5, 10, 20, 30, and 40 mg groups, and 6 each in 60 and 80 mg dose groups. Twenty subjects were divided equally into 30 and 40 mg groups for the multiple-dose study. To determine the effect of a high-fat diet on AD16, 16 subjects were administered a single 20 mg dose of AD16 under the fasted and fed condition in a single-center, randomized, open-label, two-cycle, two-crossover study. Moreover, safety and PK parameters were also assessed. RESULTS Plasma exposure to a single oral dose of AD16 increased at an approximate dose-increasing rate. The pharmacodynamic dose of the AD16 can be maintained through the accumulation effect of the drug within the safety window. Compared to fasting, ingesting a high-fat meal decelerated the rate of AD16 absorption, albeit without effect on its overall absorption. No dose-related toxicities were seen in any of the studies, all treatment-emergent adverse events were grade I/II, and no serious adverse event occurred. CONCLUSIONS The present study exhibited favorable safety, tolerability, and PK profile of AD16, supporting its further research as a potential drug treatment for AD. TRIAL REGISTRATION ClinicalTrials.gov; NCT05787028, NCT05787041, NCT05806177. The SAD and FE studies were retrospectively registered on 28 March 2023. The MAD study was retrospectively registered on 10 April 2023.
