A research report on a novel typological study of the Chinese metaphorical and metonymic idioms

This report shows a novel classification of the Chinese metaphorical and metonymic idioms based on the Spreading-Activation Model (SA Model). Identified first are three features of the source domain within the Chinese metaphorical and metonymic idioms: (1) the relationship between the source and target domains, (2) the number of source domains within idioms, and (3) the inherent characteristics of the source domain. Then drawing on the SA Model, this report arrives at a novel classification of the Chinese metaphorical and metonymic idioms into four categories: (1) Directional activation Idioms, (2) Cooperative activation Idioms, (3) Spreading activation Idioms, and (4) Superimposed activation Idioms. Discussion is made on each category and a continuum of cognitive difficulty is established with respect to understanding different categories. This classification is of great help within the realm of teaching Chinese as a foreign language.

A novel refined classification system for type 2 diabetes in adults: A Chinese retrospective cohort study

AIMS

We propose a simple type 2 diabetes mellitus (T2DM) classification method based on fasting C-peptide (FCP) levels and examined its feasibility and validity.

METHODS

Adult T2DM patients first diagnosed in our tertiary care centre from January 2009 to January 2020 were included. Patients were followed until January 2021; their clinical characteristics, chronic complications, treatment regimen, and glycaemic control were compared.

RESULTS

In total, 5644 T2DM patients were included. Three subgroups were established based on FCP levels: subtype T1 (FCP ≤ 1.0 μg/L), 1423 patients (25.21%); subtype T2 (FCP 1.0-2.5 μg/L), 2914 patients (51.63%); and subtype T3 (FCP ≥ 2.5 μg/L), 1307 patients (23.16%). T1 was characterised by older age, lower body mass indices, higher initial glycosylated haemoglobin (HbA1c) levels, and the lowest homoeostatic model assessment 2 estimates of β-cell function (HOMA2-β) and HOMA2-insulin resistance at baseline. The T3 group's clinical characteristics were opposite to those of T1. T3 patients showed higher incidence rates and risks of diabetic kidney disease, diabetic peripheral vascular disease, and non-alcoholic fatty liver, while the risks of diabetic retinopathy and diabetic peripheral neuropathy were highest in T1. Insulin, glycosidase inhibitors, and thiazolidinedione were the most frequently used drugs, but the use of metformin, dipeptidyl peptidase-4 inhibitor, and insulin secretagogue drugs was slightly lower in T1. T1 maintained higher HbA1c levels throughout follow-up. Overall HbA1c fluctuations were more significant in T3 than in T1 and T2.

CONCLUSIONS

The new adult T2DM classification is simple and clear and will help classify different T2DM clinical characteristics and guide treatment plans.

Validation of the Swedish Diabetes Re-Grouping Scheme in Adult-Onset Diabetes in China

CONTEXT

This study applied the Swedish novel data-driven classification in Chinese newly diagnosed diabetic patients and validated its adoptability.

OBJECTIVE

This study aimed to validate the practicality of the Swedish diabetes regrouping scheme in Chinese adults with newly diagnosed diabetes.

DESIGN

Patients were classified into 5 subgroups by K-means and Two-Step methods according to 6 clinical parameters.

SETTING

Ambulatory care.

PATIENTS

A cross-sectional survey of 15 772 patients with adult-onset newly diagnosed diabetes was conducted in China from April 2015 to October 2017.

INTERVENTION

None.

MAIN OUTCOME MEASURES

Six parameters including glutamate decarboxylase antibodies (GADA), age of onset, body mass index (BMI), glycated hemoglobin A1c (HbA1c), homoeostatic model assessment 2 estimates of β-cell function (HOMA2-B) and insulin resistance (HOMA2-IR) were measured to calculate the patient subgroups.

RESULTS

Our patients clustered into 5 subgroups: 6.2% were in the severe autoimmune diabetes (SAID) subgroup, 24.8% were in the severe insulin-deficient diabetes (SIDD) subgroup, 16.6% were in the severe insulin-resistance diabetes (SIRD) subgroup, 21.6% were in the mild obesity-related diabetes (MOD) subgroup and 30.9% were in the mild age-related diabetes (MARD) subgroup. When compared with the Swedish population, the proportion of SIDD subgroup was higher. In general, Chinese patients had younger age, lower BMI, higher HbA1c, lower HOMA2-B and HOMA2-IR, and higher insulin use but lower metformin usage than the Swedish patients.

CONCLUSION

The Swedish diabetes regrouping scheme is applicable to adult-onset diabetes in China, with a high proportion of patients with the severe insulin deficient diabetes. Further validations of long-term diabetes complications remain warranted in future studies.

Evaluation of a Novel Classification of Heat-Related Illnesses: A Multicentre Observational Study (Heat Stroke STUDY 2012)

The Japanese Association for Acute Medicine Committee recently proposed a novel classification system for the severity of heat-related illnesses. The illnesses are simply classified into three stages based on symptoms and management or treatment. Stages I, II, and III broadly correspond to heat cramp and syncope, heat exhaustion, and heat stroke, respectively. Our objective was to examine whether this novel severity classification is useful in the diagnosis by healthcare professionals of patients with severe heat-related illness and organ failure. A nationwide surveillance study of heat-related illnesses was conducted between 1 June and 30 September 2012, at emergency departments in Japan. Among the 2130 patients who attended 102 emergency departments, the severity of their heat-related illness was recorded for 1799 patients, who were included in this study. In the patients with heat cramp and syncope or heat exhaustion (but not heat stroke), the blood test data (alanine aminotransferase, creatinine, blood urea nitrogen, and platelet counts) for those classified as Stage III were significantly higher than those of patients classified as Stage I or II. There were no deaths among the patients classified as Stage I. This novel classification may avoid underestimating the severity of heat-related illness.

Venous intravasation as a complication and potential pitfall during hysterosalpingography: re-emerging study with a novel classification

OBJECTIVES

Presently, hysterosalpingography (HSG) is used as a means to evaluate women with infertility and repetitive pregnancy loss. Venous intravasation is a complication and potential pitfall during HSG and analogous procedures including hysteroscopy. The aim of our study was to assess the venous intravasation and to obtain critical information for more secure and more accurate procedures. In particular, the primary goal of the present study was to compare HSG without and with intravasation to identify differences seen on HSG and to assess the predisposing factors of intravasation. The secondary goal was to describe clinical- and imaging-based novel classification of intravasation.

MATERIALS AND METHODS

This study included a patient cohort of 569 patients who underwent HSG between 2008 and 2011 at our center in the absence (control group) or presence (study group) of intravasation. Intravasation classified from level 0 (no intravasation) to level 3 (severe intravasation) was compared with preprocedural (demographic and clinical) and procedural (HSG) data. Data were analyzed using Statistical Package for Social Sciences (SPSS) statistical software.

RESULTS

Of the 569 patients undergoing HSG, 528 showed no intravasation and 41 (7.2%) patients showed intravasation when associated with preprocedural (leukocytes, menometrorrhagia, secondary infertility, ectopic pregnancy, abortus, polycystic ovaries, endometriosis, and interventions) and procedural (pain, scheduling, endometrial-uterine nature, and spillage) parameters. Moreover, intravasation was lower in women with smooth endometrium, triangular uterus, and homogeneous peritoneal spillage. No association was found between age, tubal patency, increased pressure, and intravasation.

CONCLUSIONS

Using a novel classification method, intravasation can be observed in women during HSG and associates with preprocedural and procedural predisposing factors in subsumed conditions. This classification method will be useful for improving the efficiency and accuracy of HSG and related procedures by minimization of severe complications caused by intravasation.
