The aim of this study is to evaluate the effectiveness of a smart non-invasive blood glucose monitor prototype during pregnancy through clinical validation.The monitor utilizes near-infrared spectroscopy combined with AI big data analysis of photoelectric volumetric pulse wave data to achieve non-invasive monitoring of blood glucose in women during pregnancy.The research team developed a monitor that employs a sensing chip,effectively overcoming the problems of weak signals and individual differences in non-invasive blood glucose monitoring.The user experience is enhanced by visualizing the test results on the accompanying cell phone APP(application)of the smart non-invasive pregnancy blood glucose monitor.Clinical validation revealed that the non-invasive monitoring data for pregnant women aged 20～30 years significantly differed from those obtained via traditional blood glucose measurement methods,whereas no significant difference(P<0.05)was observed for pregnant women aged 31～42 years.The study concluded that further calibration of the monitor and an expansion of the sample size are necessary to enhance consistency with invasive glucose monitoring results.

Objective To establish the analytical performance specifications(APS)for routine items of biochemical inspection based on the external quality assessment(EQA)and internal quality control(IQC)data.Methods The EQA data and IQC data of routine items of biochemistry inspection in clinical laboratory center of national health commission from 2021 to 2023 were collected from the Department Clinical Laboratory of Traditional Chinese Medicine Hospital of Chengdu Pidu District.Comparing the percentage difference of the EQA data and the IQC in control imprecision[expressed as the coefficient of variation(CV)]data with the 3-level evaluation criteria derived based on biological variation(BV),the percentage pass rate of EQA data and the pass rate of CV under control were calculated,so as to achieve the quality target of APS with 80％or more as the quality control product of this level as the routine biochemical test items of the laboratory.For the inspection items that did not reach BV standard APS or were not applicable to meet the standard,the APS would be set to the WS/T 403-2012 industry standard or based on current technical level.Results TEa/allowable CV of biochemical inspection items were as follows:Potassium(K)2.4％/1.9％,Sodium(Na)4.0％/0.9％,Chloride(Cl)4.0％/0.9％,Calcium(Ca)3.4％/1.8％,Phosphate(P)9.6％/1.9％,Magnesium(Mg)3.8％/2.0％,Glucose(Glu)6.1％/2.3％,Creatinine(Crea)3.9％/2.2％,Urea(Urea)8.6％/3.3％,Total protein(TP)4.9％/2.0％,Albumin(Alb)3.3％/1.9％,Total bilirubin(TBil)6.3％/2.4％,Alanine transaminase(ALT)9.3％/2.9％,Asparpartate transaminase(AST)6.2％/2.1％,γ-glutamyl transferase activity(GGT)9.2％/2.1％,Lactate dehydrogenase(LDH)6.8％/2.2％,Alkaline phosphatase(ALP)7.2％/3.3％,Total cholesterol(TC)of 8.3％/2.6％,Triglyceride(TG)12.9％/4.9％,Amylase(AMY)5.9％/1.6％,Creatine kinase(CK)4.3％/1.6％and Uric acid(UA)2.9％/1.0％.Conclusion The APS set based on BV or current technical level can be used as a quality target for routine laboratory clinical biochemistry testing programs,and the laboratory can select the suitable APS according to the actual situation.

Patients with acute heart failure (AHF) often experience dyspnea, and monitoring and quantifying their breathing patterns can provide reference information for disease and prognosis assessment. In this study, 39 AHF patients and 24 healthy subjects were included. Nighttime chest-abdominal respiratory signals were collected using wearable devices, and the differences in nocturnal breathing patterns between the two groups were quantitatively analyzed. Compared with the healthy group, the AHF group showed a higher mean breathing rate (BR_mean) [(21.03 ± 3.84) beat/min vs. (15.95 ± 3.08) beat/min, P < 0.001], and larger R_RSBI_cv [70.96% (54.34%-104.28)% vs. 58.48% (45.34%-65.95)%, P = 0.005], greater AB_ratio_cv [(22.52 ± 7.14)% vs. (17.10 ± 6.83)%, P = 0.004], and smaller SampEn (0.67 ± 0.37 vs. 1.01 ± 0.29, P < 0.001). Additionally, the mean inspiratory time (TI_mean) and expiration time (TE_mean) were shorter, TI_cv and TE_cv were greater. Furthermore, the LBI_cv was greater, while SD1 and SD2 on the Poincare plot were larger in the AHF group, all of which showed statistically significant differences. Logistic regression calibration revealed that the TI_mean reduction was a risk factor for AHF. The BR_ mean demonstrated the strongest ability to distinguish between the two groups, with an area under the curve (AUC) of 0.846. Parameters such as breathing period, amplitude, coordination, and nonlinear parameters effectively quantify abnormal breathing patterns in AHF patients. Specifically, the reduction in TI_mean serves as a risk factor for AHF, while the BR_mean distinguishes between the two groups. These findings have the potential to provide new information for the assessment of AHF patients.

Objective:To explore the association of the total gestational weight gain (GWG) and GWG in different trimesters with adverse pregnancy outcomes during the second pregnancy in women with history of gestational diabetes mellitus (GDM).Methods:This retrospective cohort study recruited 441 singleton pregnant women with a history of GDM who gave birth at Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2017 to December 2018 as the GDM history group. Another 1 637 singleton pregnant women without a history of GDM who gave birth at the same period were selected through the mechanical sampling method as the control group. Independent sample t-test and Chi-square test were used to compare the differences in general conditions, GWG and perinatal outcomes between the two groups. Based on the Institute of Medicine guidelines for GWG, the subjects were further divided into three subgroups: inadequate GWG, adequate GWG and excessive GWG groups. Multivariate logistic regression analysis was used to compare the pregnancy outcome in women with the same GWG in different periods of pregnancy between the two groups. Results:(1) Women with GDM history had lower GWG before and after oral glucose tolerance test (OGTT) and the whole pregnancy than those without [(6.3±3.3) vs (7.9±3.7) kg, (4.8±2.6) vs (5.6± 2.6) kg, (11.8±4.6) vs (14.4± 4.6) kg; t=8.074, 5.183, 10.277; all P<0.001]. The incidence of GDM, gestational hypertension, and large for gestational age (LGA) in the GDM history group were higher than those in the control group [46.5% (205/441) vs 18.1% (296/1 637), 8.4% (37/441) vs 5.4% (88/1 637), 12.9% (57/441) vs 9.7% (158/1 637); χ2=153.181, 5.583, 4.013; all P<0.05]. (2) Before OGTT: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI for inadequate, adequate and excessive GWG were 4.02 (2.35-6.88), 3.92 (2.65-5.79) and 3.33 (2.11-5.25), respectively, all P<0.001]. Except for women with inadequate GWG, pregnancy with a history of GDM also had a higher risk of preeclampsia [ OR and 95% CI were 3.62 (1.47-9.23) and 2.22 (1.07-5.57) for adequate and excessive GWG, respectively, both P<0.05]. After OGTT: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI for inadequate, adequate and excessive GWG were 2.48 (1.60-3.84), 4.63 (2.92-7.35) and 4.22 (2.73-6.51), respectively, all P<0.001]. Pregnant women with a history of GDM with excessive GWG had an increased risk of preeclampsia ( OR=2.46, 95% CI: 1.10-5.51, P<0.05). During pregnancy: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI were 3.02(2.00-4.59), 4.08(2.76-6.04) and 2.66(1.54-4.59) for inadequate, adequate and excessive GWG, respectively, all P<0.001]. Women with GDM history had an increased risk of large for gestational age (LGA) in those with inadequate GWG and postpartum hemorrhage in those with excessive GWG [ OR and 95% CI were 1.94 (1.09-4.21) and 2.93 (1.31-6.55), respectively, both P<0.05]. Conclusions:The total GWG and GWG in different periods during the second pregnancy in women with a history of GDM are lower than those without, but with a higher risk of adverse outcomes. Even in women with the same range of GWG, GDM history still increases the risk of adverse pregnancy outcomes.

Objective: To explore the situation of interpersonal adaption and its relation to extroversion and self-control in college students. Methods: Totally 3125 college students (1497 males, 1628 females; age from 16 to24 years) were assessed with the interpersonal adaption dimension from China College Student Adjustment Scale (CCSAS), Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) and Self-Control Scale (SCS). Results: The average score of interpersonal adaption was (33. 3 ± 3. 6). Regression analysis showed that extraversion and self-control positively predicted interpersonal adaption (β = 0. 25, 0. 08), interaction of extraversion and selfcontrol negatively predicted interpersonal adaption significantly (β =-0. 08). In the introvert group, the interpersonal adaption scores were higher in students with higher self-control scores than in those with lower self-control scores (P ＜ 0. 001). Conclusion: It suggests that college students have good interpersonal adaptation. Self-control may buffer the negative effect of low extraversion on interpersonal adaption.

Diagnosis of Parkinson's disease (PD) based on speech data has been proved to be an effective way in recent years. However, current researches just care about the feature extraction and classifier design, and do not consider the instance selection. Former research by authors showed that the instance selection can lead to improvement on classification accuracy. However, no attention is paid on the relationship between speech sample and feature until now. Therefore, a new diagnosis algorithm of PD is proposed in this paper by simultaneously selecting speech sample and feature based on relevant feature weighting algorithm and multiple kernel method, so as to find their synergy effects, thereby improving classification accuracy. Experimental results showed that this proposed algorithm obtained apparent improvement on classification accuracy. It can obtain mean classification accuracy of 82.5%, which was 30.5% higher than the relevant algorithm. Besides, the proposed algorithm detected the synergy effects of speech sample and feature, which is valuable for speech marker extraction.

Objective: To explore the clinical features and prognosis in patients with Takayasu arteritis (TA) combining neurological symptoms. Methods: We retrospectively studied 274 TA patients combining neurological symptoms who admitted to our hospital from 2002-01 to 2013-10 for their clinical and imaging features with prognosis. Results: The ratio of male to female was 1:4.3 and the mean age of disease onset was at (28.2±11.2) years. The most common neurological symptom was dizziness (214/274 cases, 78.1%), most frequent type was type III TA (112 cases, 40.9%), most common affected artery was left subclavian artery (147 cases, 53.6%), and there were 77 cases (28.1%) with (3-4) branches of the aortic arch involvement. For stroke conditions, ischemic stroke was more frequently observed in patients with steno-occlusive lesions in subclavian artery and common carotid artery, while hemorrhagic stroke was more frequently found in patients with steno-occlusive lesions in descending aorta, abdominal aorta and/or renal artery. Heart failure was the most common cause of death, it was also the most common cardiovascular event in surviving cohorts. Conclusion: TA patients could have many neurological symptoms, which were related to the number and site of artery involvement.

Objective: To explore a single center large cohort of patients with Takayasu’s arteritis for their clinical manifestation and long-term outcome in China. Methods: We retrospectively analyzed 566 patients with Takayasu’s arteritis admitted in our hospital from 2002-01 to 2013-11 for their clinical characteristics, laboratory ifndings, angiographic features, treatment and long-term outcomes. Results: The patient’s ratio for female to male gender was 1 to 3.8 and the average onset age was (28.9 ± 12.0) years. The most common non-speciifc symptom, initial symptom and complication were fever (52/566 patients, 9.2%), dizziness (214 patients, 37.8%) and hypertension (392 patients, 69.3%) respectively. The patients with pulmonary artery and coronary artery involvement were 83 (14.7%) and 66 (11.7%) respectively, and 131 (23.1%) patients had faster erythrocyte sedimentation rate. The major vascular damage was steno-occlusive lesion and the most common involvement was left sub-clavian artery, which was observed in 278 (49.1%) patients. The treatments were mainly included in medication, interventional therapy, autologous blood vessel transplantation, artiifcial blood vessel transplantation and aortic valve replacement. There were 32 patients died during the mean follow-up period of (5.0 ± 0.2) years. Hypertension, complication and the progressive stage of disease were the major factors affecting prognosis in relevant patients (regression coefifcients: 4.664, 1.959 and 1.870 respectively, allP<0.05). Conclusion: Hypertension was the leading reason for patients’ hospital visit. Takayasu’s arteritis was closely related to cardiovascular disease, the early diagnosis and treatment were really important in clinical practice.
