ABSTRACT

Objective@#To determine the heterogeneity for caries prevention service preferences among children in Anhui Province, so as to provide reference for the promotion and popularization of caries prevention services for school age children.@*Methods@#Based on a discrete selection experiment, a face to face questionnaire survey was administered using a multi stage sampling method among 785 parents with children 3-12 years of age who were hospitalized in the stomatology clinics of 7 prefectures and cities in Anhui Province from October 2021 to October 2022. A mixed Logit model was used to evaluate caries prevention service preferences for children.@*Results@#Four discrete choice experiment attributes included in the study were statistically significant for choice preference ( P <0.05). Compared with the control group, parents with a high school education or above preferred caries prevention services with 70%-<80% preventive effectiveness, 2-<5 and <2 km from the service point, and a high service cost ( β =0.38, 1.66, 1.64, 0.00); female parents preferred preventive services with 70%-<80% preventive effectiveness and a high service cost ( β =0.35, 0.01 ); parents of children <7 years of age preferred services with 70%-<80% preventive effectiveness ( β =0.75); parents of children with oral health preferred preventive services during winter and summer vacations ( β =-0.28); parents of children with caries preferred preventive services with a high cost per denticle ( β =0.00)( P <0.05).@*Conclusions@#Parents with different education levels, gender, child age, and oral health status have heterogeneity in dental caries prevention service preferences. The provision of targeted and precise services can improve the participation and coverage of caries prevention services for school age children.

ABSTRACT

To date, there have been three common methods for sampling the cerebral ischemic border zone in a rat model of transient middle cerebral artery occlusion (tMCAO): the "two o'clock method", the "diagonal method", and the "parallel line method". However, these methods have their own advantages and limitations. Here, we propose a modified technique (the "rectangular method") for sampling the ischemic border zone. A rat tMCAO model was prepared under the support of a compact small animal anesthesia machine. Cerebral blood flow was monitored by high-resolution laser Doppler to control the quality of modeling, and 2,3,5-triphenyl tetrazolium chloride (TTC) staining was used for cerebral infarction location assessment. Superoxide dismutase 2 (SOD2), cysteinyl aspartate specific proteinase (caspase)-3, caspase-9, and heat shock protein 70 (HSP70) were used to verify the reliability and reproducibility of the rectangular method. The expression of biomarkers (SOD2, caspase-3, caspase-9, and HSP70) in the traditional (two o'clock method after TTC staining) and modified (rectangular method) groups were increased. There were no significant differences between the groups. The rectangular method proposed herein is based on a modification of the diagonal method and parallel line method, which could provide a directly observable infarct borderline and a sufficient sampling area for subsequent experimental operations regardless of the cerebral infarct location. The assessed biomarkers (SOD2, caspase-3, caspase-9, and HSP70) demonstrated the reliability and reproducibility of the rectangular method, which may facilitate inter-laboratory comparisons.

ABSTRACT

Objective:To investigate the difference in left ventricular dysfunction between type 2 diabetes mellitus (T2DM) patients with hyperlipidemia and those without hyperlipidemia, and analyze the application value of three-dimensional speckle tracking technology.Methods:The clinical data of 70 patients with T2DM admitted to Heji Hospital Affiliated to Changzhi Medical College from January 2020 to June 2021 were retrospectively analyzed. Among these patients, 35 patients had hyperlipidemia and 35 patients had no hyperlipidemia. At the same time, 40 healthy subjects who concurrently underwent health checkups in the same hospital were included as healthy controls. All subjects underwent routine cardiac ultrasound and 3D-STE examinations. General clinical information and left ventricular function-related parameters, including global longitudinal strain, global circumferential strain, global area strain, and global radial strain were compared between healthy controls and T2DM patients with hyperlipidemia and those without hyperlipidemia.Results:The proportion of left ventricular remodeling increased in T2DM patients without hyperlipidemia, and the proportion of left ventricular hypertrophy was the highest in T2DM patients with hyperlipidemia. Global longitudinal strain and global circumferential strain in T2DM patients without hyperlipidemia were (-16.97 ± 2.59)% and (-17.41 ± 2.50)%, respectively, which were significantly higher than (-18.86 ± 2.46)% and (-18.71 ± 2.92)% in healthy controls ( t = 0.95, 0.57, both P < 0.05). Global longitudinal strain, global circumferential strain, and global area strain in T2DM patients with hyperlipidemia were (-14.98 ± 3.15)%, (-15.80 ± 3.16)%, (-27.17 ± 4.54)%, respectively, which were significantly higher than (-18.86 ± 2.46)%, (-18.71 ± 2.92)%, (-30.62 ± 4.02)% in healthy controls ( t = 0.46, 1.37, 0.98, all P < 0.05) and (-16.97 ± 2.59)%, (-17.41 ± 2.50)%, (-30.06 ± 3.59)% in T2DM patients without hyperlipidemia ( t = 0.37, 1.02, 0.77, all P < 0.05). Global radial strain in T2DM patients with hyperlipidemia was significantly higher than [(51.49 ± 8.94)%, t = 1.35, P < 0.05] in healthy controls and [(47.71± 8.46)%, t = 0.98, P < 0.05] in T2DM patients without hyperlipidemia. In patients with T2DM, fasting blood glucose and hyperlipidemia were independently correlated with all strain-related parameters. Conclusion:Hyperlipidemia can aggravate left ventricular remodeling and dysfunction in patients with T2DM and 3D-STE is one of the examination methods for subclinical left ventricular remodeling and dysfunction in T2DM patients with or without hyperlipidemia.

ABSTRACT

Background/Aims@#We evaluated the clinical significance and prognostic power of functional luminal imaging probe (FLIP) panometry in patients with achalasia treated with peroral endoscopic myotomy (POEM), and examined the clinical parameters associated with symptomatic improvement and the presence of contractility (POC) following POEM. @*Methods@#We reviewed the electronic medical records of patients with achalasia treated with FLIP panometry and POEM at a tertiary teaching hospital in Seoul, Republic of Korea. Follow-up examination was composed of esophageal manometry and questionnaires on symptoms. We analyzed the FLIP data by interpolating using the cubic spline method in MATLAB. @*Results@#We retrospectively analyzed 33 men and 35 women (mean age: 52 ± 17 years), of whom 14, 39, and 15 patients were diagnosed with achalasia types I, II, and III, respectively. The FLIP panometry diagnoses were reduced esophagogastric junction opening (REO) with a retrograde contractile response (n = 43); REO with an absent contractile response (n = 5); REO with a normal contractile response (n = 11); and a retrograde contractile response (n = 9). Overall, the patients showed improvements in Eckardt scores following POEM from 6.48 ± 2.20 to 1.16 ± 1.15 (P < 0.01). Post-POEM symptomatic improvement was not significantly associated with any of the clinical parameters, including panometry diagnosis. Conversely, post-POEM POC was significantly associated with the presence of repetitive antegrade contractions and achalasia subtypes (both P < 0.01). @*Conclusion@#While FLIP panometry was not significantly associated with the clinical course of achalasia, FLIP panometry was associated with POC following POEM and may complement manometry in the functional evaluation of esophageal motility disorders.

ABSTRACT

@#With the arrival of the era of big data, increasing attention has been drawn to the application of artificial intelligence (AI) in the medical field. AI has many advantages, such as objectivity, accuracy, minimal invasiveness, time savings and high efficiency. Therefore, the combination of AI with dental diagnosis and treatment can help dentists improve work efficiency and save medical resources, offering potential significant benefits for dental application. At present, AI has been gradually integrated into prosthodontics, oral and maxillofacial surgery, orthodontics, endodontics and periodontics. The AI system can realize automatic tooth preparation, automatic tooth arrangement and implantology. Deep learning can be used to assist in diagnosing maxillary sinus inflammation, predicting the complications of tooth extraction and improving the accuracy of osteotomy. The AI system can also provide significant clues for the diagnosis, treatment and prognosis of oral and maxillofacial tumors. The breakthrough brought by AI in cephalometric and the assessment of facial attractiveness of patients has promoted the development of intelligent and personalized orthodontic treatment. Deep learning and analysis of medical images also promote the accuracy of root canal therapy as well as the diagnosis and treatment of periodontal diseases. AI technology has realized the leap from digitalization to automation and intelligence in oral diagnosis and treatment, and its application potential in the oral field should not be underestimated. Based on the concepts of AI, this paper will focus on the application of artificial intelligence in various oral clinical fields and briefly introduce its advantages, problems and future.

ABSTRACT

The brain and heart has a tight relationship upon physiology and pathology during the development of cardiovascular and cerebrovascular diseases with clinical conditions interacting with each other and complex pathological mechanisms. Clinical studies prove that cerebral diseases such as stroke usually happen with cardiac diseases as complications, and cardiac diseases such as atrial fibrillation can also cause cerebral diseases, which can even aggravate brain atrophy and lead to cognitive impairment. Traditional Chinese medicine (TCM) also believes that “the substance of Shenming is located in the brain and the function in the heart.” Specifically, Yuanshen is in the brain and Shishen is in the heart, which thus makes the heart and brain closely related. If Shenming in any of them is impaired, the other one would also be injured. Therefore, the pathological mechanisms of brain-heart mutual damage have become one of the current research hotspots. This paper, combined with the clinical research status of the brain-heart mutual damage, summarized its pathological mechanisms from the perspectives of inflammatory responses, dysregulation of autonomic nervous system, apoptosis, energy metabolism and oxidative stress. The necessity of “brain-heart concurrent regulation” was proposed and the research progress on the treatment of cerebral and cardiac diseases with TCM represented by Naoxintong capsule was profiled in the light of heart and brain function described by TCM and the holistic concept of TCM treating cerebral and cardiac diseases. This paper reviews the pathological mechanisms of brain-heart mutual damage and the research progress on its treatment with TCM, which can provide reference for the prevention and treatment of cardiovascular and cerebrovascular diseases and further research on them.

ABSTRACT

In the era of climate change, due to increased incidences of a wide range of various environmental stresses, especially biotic and abiotic stresses around the globe, the performance of plants can be affected by these stresses. After oxygen, silicon (Si) is the second most abundant element in the earth's crust. It is not considered as an important element, but can be thought of as a multi-beneficial quasi-essential element for plants. This review on silicon presents an overview of the versatile role of this element in a variety of plants. Plants absorb silicon through roots from the rhizospheric soil in the form of silicic or monosilicic acid. Silicon plays a key metabolic function in living organisms due to its relative abundance in the atmosphere. Plants with higher content of silicon in shoot or root are very few prone to attack by pests, and exhibit increased stress resistance. However, the more remarkable impact of silicon is the decrease in the number of seed intensities/soil-borne and foliar diseases of major plant varieties that are infected by biotrophic, hemi-biotrophic and necrotrophic pathogens. The amelioration in disease symptoms are due to the effect of silicon on a some factors involved in providing host resistance namely, duration of incubation, size, shape and number of lesions. The formation of a mechanical barrier beneath the cuticle and in the cell walls by the polymerization of silicon was first proposed as to how this element decreases plant disease severity. The current understanding of how this element enhances resistance in plants subjected to biotic stress, the exact functions and mechanisms by which it modulates plant biology by potentiating the host defence mechanism needs to be studied using genomics, metabolomics and proteomics. The role of silicon in helping the plants in adaption to biotic stress has been discussed which will help to plan in a systematic way the development of more sustainable agriculture for food security and safety in the future.

ABSTRACT

OBJECTIVE@#To investigate the protective effect of melatonin against myocardial ischemia reperfusion (IR) injury in isolated rat hearts and explore the underlying mechanisms.@*METHODS@#The isolated hearts from 40 male SD rats were randomly divided into 4 groups (=10): the control group, where the hearts were perfused with KH solution for 175 min; IR group, where the hearts were subjected to global ischemia for 45 min followed by reperfusion for 120 min; IR+melatonin (Mel+IR) group, where melatonin (5 μmol/L) was administered to the hearts 1 min before ischemia and during the first 5 min of reperfusion, followed by 115 min of reperfusion; and IR+2, 3-butanedione monoxime (IR+BDM) group, where the hearts were treated with BDM (20 mmol/L) in the same manner as melatonin treatment. Myocardial injury in the isolated hearts was assessed based on myocardial injury area, caspase-3 activity, and expressions of cytochrome C and cleaved caspase-3 proteins. Cardiac contracture was assessed using HE staining and by detecting lactate dehydrogenase (LDH) activity and the content of cardiac troponin I (cTnI) in the coronary outflow, measurement of left ventricular end-diastolic pressure (LVEDP) and electron microscopy. The content of ATP in the cardiac tissue was also determined.@*RESULTS@#Compared with those in the control group, the isolated hearts in IR group showed significantly larger myocardial injury area and higher caspase-3 activity and the protein expressions of cytochrome C and cleaved caspase-3 with significantly increased LDH activity and cTnI content in the coronary outflow and elevated LVEDP at the end of reperfusion; HE staining showed obvious fractures of the myocardial fibers and the content of ATP was significantly decreased in the cardiac tissue; electron microscopy revealed the development of contraction bands. In the isolated hearts with IR, treatment with Mel or BDM significantly reduced the myocardial injury area, caspase-3 activity, and protein expressions of cytochrome C and cleaved caspase-3, obviously inhibited LDH activity, lowered the content of cTnI and LVEDP, reduced myocardial fiber fracture, and increased ATP content in the cardiac tissue. Both Mel and BDM inhibited the formation of contraction bands in the isolated hearts with IR injury.@*CONCLUSIONS@#Mel can alleviate myocardial IR injury in isolated rat hearts by inhibiting cardiac contracture, the mechanism of which may involve the upregulation of ATP in the cardiac myocytes to lessen the tear of membrane and reduce cell content leakage.

ABSTRACT

Gastroparesis is a condition characterized by delayed gastric emptying without evidence of mechanical obstruction in the stomach. Its symptoms include nausea, vomiting, early satiety, abdominal bloating, and abdominal pain. Most cases of gastroparesis are either idiopathic, due to diabetes mellitus, or post-surgical complications. The diagnosis of gastroparesis requires upper endoscopy, contrast radiography, or validated gastric scintigraphy. Gastroparesis is managed with nutritional support and treatment of any underlying disorders, such as diabetes. Pharmacological treatments have been tried, including prokinetics and novel medications. Interventions focused on the pylorus have shown promising results.

ABSTRACT

Objective:To evaluate the efficacy and safety of regional citrate and heparin anticoagulation in continuous renal replacement therapy (CRRT) in critically ill patients by Meta-analysis.Methods:Randomized controlled trials (RCT) comparing the efficacy and safety of regional citrate and heparin anticoagulation in English or Chinese were retrieved from Medline, Embase, Cochrane library, Web of Science, CNKI, Wanfang Database by electronic and manual search before December 2019. The primary outcomes were mortality and circuit life span, and the secondary outcomes were complications such as bleeding, heparin-induced thrombocytopenia (HIT), metabolic alkalosis, and hypocalcemia. Meta-analysis of the literature was conducted using the methods recommended by the Cochrane Collaboration's software RevMan 5.3 and funnel plot was used to analyze whether there was publication bias in each study.Results:Sixteen RCTs with 1 229 patients were included. Meta-analysis showed that there was no significant difference in mortality between the regional citrate and heparin anticoagulation in CRRT [relative risk ( RR) = 0.95, 95% confidence interval (95% CI) was 0.83-1.09, P = 0.47]. The circuit life span in the regional citrate group was 15.37 hours (95% CI was 10.09-20.65, P < 0.000 01) longer than that in the heparin group. Bleeding risk ( RR = 0.29, 95% CI was 0.19-0.44, P < 0.000 01) and HIT ( RR = 0.35, 95% CI was 0.16-0.74, P = 0.006) were lower in the regional citrate group than those in the heparin group, whereas the regional citrate anticoagulation could cause hypocalcemia ( RR = 4.67, 95% CI was 1.88-11.60, P = 0.000 9). There was no significant difference in the incidence of metabolic alkalosis between the two groups ( RR = 0.76, 95% CI was 0.42-1.37, P = 0.36). The funnel plot showed that there were no significant publication bias in the included studies. Conclusion:Regional citrate anticoagulation could significantly prolong circuit life span and decrease the risk of bleeding, and should be preferentially selected for the CRRT anticoagulation in critically ill patients.

ABSTRACT

The clinical benefit of adjuvant intravenous immunoglobulin (IVIG) therapy is controversial in immunocompromised patients with severe varicella. A twenty-one-year-old woman who had received a kidney transplant one year earlier presented with fever and generalized rash for 5 days. Initial immunoglobulin M (IgM) and IgG for varicella zoster virus (VZV) were negative; however, the patient was diagnosed with varicella with fulminant hepatitis because VZV-specific PCR from skin vesicles and blood was positive. The patient received intravenous acyclovir and 5-day IVIG. The decline of plasma viral load was steeper (beta coefficient −0.446) during IVIG therapy than after the therapy (beta coefficient −0.123) (P = 0.04), while VZV glycoprotein IgG titers and VZV-specific T cell responses were not detected during the 5-day IVIG therapy. The patient improved without any complications. This case provides an experimental evidence that adjuvant IVIG can significantly reduce viral load in immunocompromised patients with severe varicella.

ABSTRACT

Objective: To study the protective effect and mechanism of compound Danshen dropping pills on the heart of rats with type 2 diabetic cardiomyopathy. Method: Seventy-five male SD rats were randomly divided into blank group (15 rats) and model group (60 rats). The model group was fed with high-sugar and high-fat diet, high-sugar and high-fat milk and sucrose water. Six weeks later, rats with foodborne obesity (body mass ≥ the mean body mass of blank control group + 2 times standard deviation) were selected and intraperitoneally injected with 1% streptozotocin (STZ)28 mg·kg-1. After 12 weeks, rats with fasting blood glucose ≥ 11.1 mmol·L-1 and polydipsia, diuresis, polyphagia and weight loss were randomly divided into model group, compound Danshen dropping pills group (0.5 g·kg-1) and metformin group (0.5 g·kg-1) and intervened for 12 weeks. At the end of the experiment, echocardiography was used to evaluate cardiac function. Blood samples were taken to determine the corresponding biochemical indicators of rats. Histopathological changes of myocardium were observed by hematoxylin-eosin (HE) and Masson staining. The ultrastructure of myocardium was observed under electron microscope. Western blot was used to detect the expressions of vascular endothelial growth factor (VEGF), transforming growth factor-beta 1 (TGF-β1) and type Ⅰ collagen (Collagen Ⅰ). Real-time fluorescence quantitative analysis (Real-time PCR) was used to detect the expression of miRNA-200b. Result: Compared with the blank group, the heart weight index (HMI), fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterin(LDL-C) levels in the model group were significantly increased (PPPPPβ1 and Collagen I increased (PPPPPPβ1 and Collagen I was decreased (PPConclusion: Compound Danshen dropping pills may play a protective role in the heart of type 2 diabetic cardiomyopathy rats by lowering lipid, up-regulating the expression of miR-200b and inhibiting the expression levels of VEGF, TGF-β1 and Collagen I.

ABSTRACT

Objective:To establish a high performance liquid chromatography (HPLC) method for determination of four active constituents, namely MSTG-A,MSTG-B,gaultherin and chlorogenic acid in the anti-inflammatory and analgesic active fraction (ARF) of the ethnic medicine Gaultheria leucocarpa var. yunnanensis, in order to provide a methodological basis for the in-depth study and quality control of G. leucocarpa var. yunnanensis,and lay a foundation for later preparation and clinical application. Method:The determination was performed on COSMOSIL 5C18-PAQ (4.6 mm×250 mm,5 μm) column with methanol-0.2% glacial acetic acid (gradient elution) as the mobile phase at a flow rate of 1 mL·min-1. The column temperature was 25℃. The detection wavelength was set at 294 nm. Result:The linear range of MSTG-B,MSTG-A,gaultherin and chlorogenic acid were 0.014 06-0.450 00,0.007 81-0.250 00,0.003 13-0.100 00,0.000 94-0.030 00 g·L-1 (r ≥ 0.999 7),respectively,with a good precision,repeatability and stability. And the average recoveries were 100.81%,98.99%,96.12% and 102.56%,respectively. RSDs were 1.4%,0.7%,0.7%,2.4%,respectively. The contents of MSTG-B,MSTG-A,gaultherin and chlorogenic acid in ARF fraction of G. leucocarpa var. yunnanensis were 23.608,41.973,8.282,2.673 mg·g-1,respectively. Conclusion:The established method was simple and accurate, with a high repeatability. It can be used for determination of four active constituents in ARF fraction of G. leucocarpa var. yunnanensis,so as to provide a reference for the in-depth research,quality control and comprehensive evaluation of G. leucocarpa var. yunnanensis and lay a solid foundation for preparation and clinical application.
