Understanding heart development at a molecular level is a prerequisite for uncovering the causes of congenital heart diseases .Such knowledge can also greatly benefit therapeutic approaches that try to enhance cardiac regeneration or that involve the differentiation of resident cardiac progenitor cells .Wnt proteins have been shown to play multiple roles dur-ing cardiac development .They are extracellular growth factors that activate different intracellular signaling branches .Here, we summarize our current understanding of how these factors affect different aspects of cardiogenesis , from early specifica-tion of cardiac progenitors to later developmental steps , such as remodeling processes .

Objective To explore related factors affecting bone mineral density (BMD) and osteoporosis (OP) in patients with type 2 diabetes mellitus (T2DM). Methods Dual-energy X-ray absorptiometry was used to measure BMD of the femoral neck and the lumbar vertebrae in 220 patients with T2DM. All the patients were divided into three groups:normal bone mass group, decreased bone mass group and OP group according to the value of BMD. The clinical data and biochemical indicators were compared and analyzed between these groups, and the influencing factors of T2DM and OP were explored. Results Compared with normal bone mass group and decreased bone mass group, there were more older patients, longer course of T2DM, lower BMI and high density lipoprotein cholesterol (HDL-C), and higher glycated hemoglobin (HbA1c) level in OP group. There were significantly higher age, longer course of T2DM, higher level of HbA1c, and lower levels of BMI, HDL-C in decreased bone mass group than those of normal bone mass group (P＜0.05). There were no significant differences in waist-to-hip ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP), postmenopausal women (PMW) ratio, fasting plasma glucose (FPG), 2-h postprandial blood glucose (2hPG), blood phosphorus, calcium, total cholesterol (TC), three acyl glycerin (TG) and low-density lipoprotein cholesterol (LDL-C) between three groups. The risk factors for T2DM combined with OP were older, female, long duration of T2DM, higher levels of FPG, 2hPG and HbA1c. Conclusion Older and female T2DM patients were high-risk group of OP. The treatment plan should be timely adjusted by regularly monitoring indexes of blood glucose and HbA1c.

Objective To systematically review the efficacy and safety of drug-eluting stent(DES) versus coronary artery bypass grafting(CABG) in the treatment of left anterior descending coronary artery(CAD) stenosis.Methods Literature about the efficacy and safety of DES versus CABG for LAD stenosis was retrieved from digital databases of MEDLINE, EMbase, PubMed, and the Cochrane Library by November 2016.Data extraction and quality assessment of included studies were conducted by two independent reviewers.RevMan 5.3 software was used to perform meta-analysis.Results Ten studies involving 9771 patients were finally included.The results of meta-analysis showed that there was no significant difference in mortality [RR=0.88,95%CI(0.70,1.11),P=0.28],major adverse cardiovascular events[MACE,RR=1.04,95%CI(0.88,1.24),P=0.63] or myocardial infarction [MI,RR=0.92,95%CI(0.56,1.53),P=0.75], but PCI-DES significantly increased the risk of TVR [OR=2.43,95%CI(1.61,3.69),P<0.0001].Conclusion For LAD stenosis, PCI-DES strategy causes as high a rate of mortality, MACE and MI as CABG or DES, but PCI-DES can significantly increase the risk of TVR, so we should be cautious clinically.

Objective To investigate the significance of XAGE-1bmRNA expression in the blood specimens of patients with primary liver cancer, cirrhosis and benign liver diseases and in healthy individuals. Methods Venous blood specimens of patients with primary liver cancer (n= 125), cirrhosis (n= 23), benign liver diseases (n= 34) and healthy individuals (n = 41 ) were collected. XAGE-1b mRNA was detected by real-time fluorescence quantitative PCR. Results The expression levels of XAGE-1b mRNA in patients with primary liver cancer, cirrhosis, benign liver diseases and healthy in dividuals were 3.72 (0.93, 10.2) ×10-5, 0 (0, 0. 56) ×10-5, 0 (0, 0)×10-5, 0 (0, 0) ×10-5, respectively. The XAGE-1b mRNA expression in patients with primary liver cancer was obviously higher than the patients with cirrhosis, benign liver diseases and in healthy individuals. The expression levels for patients with cirrhosis was higher than patients with benign liver diseases and in healthy individuals. The expression levels for patients with benign liver diseases and healthy individuals were similar. With a optimal cut-off value of 8. 385 × 10-7 , the sensitivity, specificity, positive predictive value, and negative predictive value of XAGE-lb mRNA for diagnosing primary liver cancer were 80. 0%, 89.8%, 90.9% and 77.9% respectively. The positive rates for patients with primary liver cancer and cirrhosis were 80.0% and 30.4% respectively. Conclusion XAGE-lb mRNA can be used as a tumor marker for primary liver cancer. It contributes to the differentiation between primary liver cancer, cirrhosis and benign liver diseases.

Carpal tunnel syndrome(CTS)is one of the most common peripheral nerve entrapment disorders,the elevated pressure in the carpal tunnel,high-intensity activities and obesity are the main causes,and the patients with mild to moderate CTS are more prevalent.The main pathogenesis of CTS involves the increasing of carpal tunnel pressure and impaired local blood oxygen supply leading to reduced nerve conduction.Currently,the clinical treatment methods for mild to moderate CTS mainly include surgical and nonsurgical treatments.Nonsurgical treatment is the preferable choice for the patients with mild to moderate CTS.The western medical treatment primarily rely on oral medications,but their long-term use is limited due to the certain adverse effects;the local blockade and extracorporeal shock wave therapies show better efficacy for the patients with frequent activities and severe symptoms;the traditional Chinese medicine treatment also becomes a choice for some CTS patients due to their advantages of less pain,lower medical costs,and significant effectiveness.This study reviews the recent advancements in the pathogenesis and treatment of mild to moderate CTS,in order to design the personalized treatment methods for the mild to moderate CTS patients based on their specific conditions in clinical settings and provide the references for precise treatment of the mild to moderate CTS patients.

Gastric ulcer is a common digestive system disease,and the long-term use of non-steroidal anti-inflammatory drugs(NSAIDs)is the second most important cause.NSAID-induced gastric ulcer animal models are key experimental tools for studying the pathogenesis,corresponding treatment method,and effective mechanisms of NSAID-induced gastrointestinal injury.However,there are currently a lack of reviews on NSAID-induced gastric ulcer animal models.This review summarizes and compares the relevant literature on animal research into indomethacin-and aspirin-induced gastric ulcers in the past 10 years,including the selection of experimental animals,drug solvents,and specific modeling method.The limitations of current models,such as the cumbersome modeling method,incomplete modeling details,inadequate models for clinical use,and lack of comparative drug research,are discussed.Feasible solutions are proposed with the aim of providing an effective reference for research in this field.

Objective:To investigate the diagnostic value of quantitative parameters of synthetic MRI in patients with prostate cancer (PCa).Methods:From April 2018 to April 2019, 25 PCa patients confirmed by whole-mount pathology were prospectively enrolled in Beijing Hospital. All patients underwent prostate MRI examinations including DWI and synthetic MRI. Four kinds of tissue types were identified in pathology, including PCa, stromal hyperplasia (SH), glandular hyperplasia (GH) and prostatitis. According to the pathological results, quantitative parameters including ADC, T 1, T 2 and proton density (PD) values were measured on DWI and synthetic MRI. One-way analysis of variance or Kruskal-Wallis H test was performed to compare the difference of each parameter among PCa, SH or GH in the transitional zone (TZ). The difference of each parameter between PCa and prostatitis in the peripheral zone (PZ) was evaluated by using independent sample t test or Mann-Whitney U test. The diagnostic performance of each parameter in discriminating PCa from other benign conditions was evaluated by using ROC curve. Area under the curve (AUC) of each parameter was compared by using DeLong test. Results:The overall differences of T 1, T 2 PD and ADC values were statistically significant among PCa and other benign conditions. The T 1, T 2 and ADC values of PCa in the TZ were lower than those in the SH ( P=0.041, 0.030,<0.001) and GH (all P<0.001). The PD value of PCa in the TZ was lower than that in the GH ( P=0.040). The differences of T 1, T 2, PD and ADC values between PCa and prostatitis in the PZ were significant ( P<0.05). The AUC of ADC value (0.943) was higher than that of T 1 (0.691, P=0.001), PD (0.555, P=0.002) and T 2 (0.754, P=0.016) values in differentiating PCa from SH. For discriminating PCa and GH, T 1, T 2 and ADC showed similar AUC ( P>0.05), which were higher than AUC of PD value ( P=0.001). For discriminating PCa and prostatitis, T 1, T 2, PD and ADC values showed similar AUC ( P>0.05). Conclusions:Quantitative parameters of synthetic MRI were practical tools for discriminating PCa from other benign pathologies.

ObjectiveBased on literature data mining， this study explores the modeling elements of diarrhea-predominant irritable bowel syndrome （IBS-D） animal models in China and abroad， providing references and suggestions for improving modeling methods and evaluation indicators. MethodsRelevant literature on IBS-D animal experiments from 2014 to 2024 was retrieved through computer searches in databases such as China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， Chinese Medical Journals Full-text Database， and PubMed. Information on experimental animal species， gender， body weight， modeling methods， modeling periods， intervention controls， modeling standards， and detection indicators was organized. Microsoft Excel 2021 software was used to establish a database and perform statistical analysis to examine the characteristics of IBS-D animal models. ResultsA total of 398 articles that met the inclusion criteria were reviewed. The IBS-D animal models were predominantly established using SD rats， Wistar rats， and C57BL/6 mice. Male animals were more commonly used， with rats typically aged 6-8 weeks and mice aged 4-6 weeks. In terms of interventions， piverium bromide was the main Western medicine， Tongxieyaofang was the primary Chinese medicine， and electroacupuncture was the primary acupuncture method. Among the modeling methods， the multi-factor combined composite modeling approach was the most common. Modeling periods were mainly concentrated between 1-14 days and 15-30 days. The success criteria for modeling were mainly evaluated based on the animal's general condition， fecal appearance， visceral sensitivity， gastrointestinal motility， behavior， and pathology. Detection indicators included apparent indexes， pathological markers， biochemical indicators， oxidative stress， brain-gut peptides， neurotransmitters， inflammatory factors， immune function， intestinal permeability， autophagy， apoptosis， proteins related to relevant signaling pathways， intestinal microbiota and its metabolites， etc. ConclusionThere are various methods for establishing IBS-D animal models， but no unified and universally accepted method has been established. The operation of the same modeling methods and the evaluation standards of the models vary across studies. Based on the results of data mining， the authors suggest that the multi-factor combined composite modeling approach most closely reflects the pathophysiological processes of IBS-D， better simulating the complex clinical symptoms of IBS-D patients， such as abdominal pain and diarrhea， and has a high degree of clinical relevance. This method is relatively recommended. While animal models in general align with Western medicine standards， models incorporating traditional Chinese medicine （TCM） syndromes are relatively few. Therefore， one of the future directions for research is to establish IBS-D animal models that meet the combined clinical disease and syndrome requirements of both Western and Chinese medicine.
