Objective·To explore the clinical efficacy and safety of sticky bone[deproteinized porcine bone mineral granules combined with advanced platelet-rich fibrin(A-PRF)and liquid platelet-rich fibrin(L-PRF)]in the repair of unilateral alveolar cleft.Methods·Patients diagnosed with unilateral alveolar cleft who met the inclusion and exclusion criteria were recruited from December 1,2023 to August 31,2024.The patients were randomly divided into 2 groups.The experimental group received sticky bone grafts,and the control group received autologous iliac cancellous bone grafts for alveolar cleft repair.The primary efficacy index was the bone resorption rate at 6 months post-surgery,calculated by measuring the grafted bone volume immediately after surgery and at 6 months using Simplant Pro 17.01 software based on patients'computed tomography data collected before surgery,immediately after surgery,and 6 months post-surgery.Secondary efficacy indices included bone density at 6 months after surgery,the occurrence of postoperative complications in patients,and the scores on the oral health-related quality of life scale.Prism 10 software was used for data analysis,and t-test and Pearson correlation analysis methods were adopted.Results·Seventeen patients with unilateral alveolar cleft were included in the experimental group,and 15 in the control group.The remaining bone volume in the experimental group at 6 months after surgery was more than that in the control group.The bone resorption rate in the experimental group was 33.24%±17.16%,significantly lower than 66.31%±17.98%in the control group(P<0.001).One patient in the experimental group had vestibular mucosal dehiscence accompanied by bone powder discharge 2 weeks after surgery;3 patients in the control group had vestibular mucosal dehiscence accompanied by cancellous bone discharge 1 month after surgery,with one case of grafted bone necrosis 4 months after surgery.The bone density in the experimental group at 6 months after surgery was significantly higher than that in the control group(P<0.001),and the scores on the oral health-related quality of life scale were lower.Conclusion·Compared with iliac cancellous bone,when sticky bone is used in the treatment of patients with unilateral alveolar cleft,it shows a lower bone resorption rate and higher bone density,indicating better osteogenic ability.Fewer number of complications and lower scores on the oral health-related quality of life scale suggest greater safety,thereby supporting its strong potential for clinical promotion and application.

Objective:This study aimed to explore whether there are abnormalities in the kynurenine pathway in patients with depression and suicidal ideation, and their dynamic relationship with clinical symptoms.Methods:According to the DSM-5 diagnostic criteria, a total of 68 patients with depression were prospectively enrolled, including 28 males and 40 females, aged( M ( Q1, Q3)) 22.0 (17.3, 47.8) years, who were the inpatients in the Division of Mood Disorders of Shanghai Mental Health Center from July 2019 to July 2022. The depressed patients were divided into groups with ( n=41) or without suicidal ideation ( n=27) based on whether they chose "weak" or "moderate to strong" suicidal ideation in questions 4 and 5 of the Beck Scale for Suicide Ideation (BSI). And 72 gender-matched healthy controls were also enrolled, including 29 males and 43 females, aged 25.5 (24.0, 36.8) years. Hamilton Depression Rating Scale-24 (HAMD 24), Hamilton Anxiety Rating Scale (HAMA), and BSI were used to evaluate the depression symptoms, anxiety symptoms, and suicidal ideation of depressed patients. All the participants received fasting venous blood collection to measure the levels of kynurenine metabolites in plasma. Among them, depressed patients with suicidal ideation were followed up, and the assessment s of depression symptoms, anxiety symptoms, and suicidal ideation, as well as kynurenine metabolites measurements, were repeated at the end of the 2nd and 4th weeks. Ultra-high performance liquid chromatography-triple quadrupole mass spectrometry was used to measure the levels of kynurenine metabolites in plasma. The hematological indicators were log-transformed, Z-score standardized, and false discovery rate correction was used for multiple comparisons of different metabolites. The relationship between baseline kynurenine metabolites and scale scores was analyzed. The relationship between kynurenine metabolites and scale scores during the follow-up process was analyzed by a linear mixed-effects model. Results:The peripheral picolinic acid (0.39±0.87 vs -0.23±1.09, t=3.89), 3-hydroxykynurenine/kynurenine (3-HK/KYN) (0.38±0.85 vs -0.09±1.01, t=2.98) and 3-HK (0.31±0.81 vs 0.14±1.04, t=2.78) of patients with depression were lower than those of healthy controls (both P<0.05). No statistically significant difference was found between patients with depression with or without suicidal ideation in kynurenine metabolites. In patients with depression and suicidal ideation, baseline HAMD 24 and HAMA scores were positively correlated with plasma 3-HK (HAMD 24: r=0.38; HAMA: r=0.39) and 3-HK/KYN (HAMD 24: r=0.34; HAMA: r=0.37) levels (all P<0.05). After adjusting for age and gender factors, a linear mixed-effects model was established for the follow-up scale scores, and kynurenine metabolite levels of this group of patients, and the results showed that the positive effect of HAMA score on 3-HK/KYN during follow-up was statistically significant ( B=0.04, t=2.46, P<0.05). Conclusion:There are abnormalities in the kynurenine pathway of tryptophan metabolism in patients with depression. 3-HK and 3-HK/KYN are related to the severity of depression and anxiety in patients with depression and suicidal ideation, among which 3-HK/KYN, representing the activity of kynurenine-3-monooxygenase, is dynamically associated with anxiety level.

Objective:To identify serum metabolic markers for early prediction and diagnosis of gestational diabetes mellitus (GDM).Methods:A retrospective case-control study was conducted.The study subjects were from pregnant women enrolled in the Birth Cohort Study of the Women′s Hospital, Zhejiang University, from1 November 2018 to 30 March 2020.100 cases of GDM (GDM group, Age 36.03±3.91) and 150 non-GDM pregnant women matched for clinical information (control group, Age35.49±3.46) were retrospectively selected for the study. Fasting serum samples were collected at 15-20 weeks of gestation (prior to GDM diagnosis, T1 period) and 24-28 weeks of gestation (during GDM diagnosis, T2 period). Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to quantify GDM-related serum metabolic small molecules, including 1, 5-anhydroglucitol, 3-hydroxybutyric acid, phenylalanine, and isoleucine. These molecules, along with basic clinical information (age, gestational week, BMI) and standard biochemical indicators (FPG), were used to develop predictive models for the early detection of GDM at T1 and the diagnosis of GDM at T2. Statistical analysis was performed using t-tests or Mann-Whitney U-tests.Result:The results of the targeted quantitative validation study indicate: At the T1 stage, the level of 1, 5-anhydroglucitol was found to be significantly lower ( P=0.001) in the GDM group compared to the control group. Conversely, the level of isoleucine was significantly higher ( P=0.027) in the GDM group. There were no significant differences in the levels of 3-hydroxybutyrate and phenylalanine between the two groups ( P>0.05). The combination of the 4 metabolites yielded the highest predictive value (AUC) for GDM at T1, with an AUC of 0.670 (95% CI: 0.602-0.739), P<0.001.At the T2 stage, the GDM group had significantly lower levels of 1, 5-anhydroglucitol ( P<0.05) and significantly higher levels of 3-hydroxybutyric acid and isoleucine ( P<0.05) than the control group, with no significant differences in phenylalanine levels ( P=0.626). The combination of the four metabolites had the highest diagnostic value (AUC) for GDM, 0.717 (95% CI 0.651-0.783), P<0.001.The analysis of seven different combinations of GDM prediction/diagnostic models created by combining four metabolites with basic clinical information and routine biochemical indicators showed: We found that the AUC value of the GDM diagnostic model built with FPG, BMI, pre-pregnancy BMI, age, gestational week, and the 4 metabolite indicators in T2 stage was the best, 0.794 (95% CI 0.736-0.851), P<0.001, with a sensitivity of 72%;The best AUC value for the GDM prediction model built with the same indicators at T1 was 0.711(95% CI 0.646-0.776), P<0.001, with a sensitivity of 77%. Conclusions:Four metabolic small molecules, 1, 5-anhydroxyglucitol, 3-hydroxybutyric acid, phenylalanine, and isoleucine, were integrated with clinical indicators (FPG) and clinical information (age, gestational week, BMI) to develop a predictive model for GDM at gestation (T1) and a diagnostic model for GDM at gestation (T2), demonstrating promising clinical prediction and diagnostic capabilities. 1, 5-Anhydroglucitol, 3-hydroxybutyric acid, phenylalanine, and isoleucine show potential as valuable markers for the prediction and diagnosis of GDM.

Purpose: The aim of this study was to assess carotid stiffening in a pre-hypertensive (PHT) population using ultrafast pulse wave velocity (ufPWV). Methods: This study retrospectively enrolled 626 individuals who underwent clinical interviews, serum tests, and assessments of the systolic blood pressure (SBP), diastolic blood pressure (DBP), carotid intima-media thickness (cIMT), pulse wave velocity-beginning of systole (PWV-BS), and pulse wave velocity-end of systole (PWV-ES) between January 2017 and December 2021. The patients were divided into three groups according to their blood pressure (BP)—normal BP (NBP): SBP <130 mmHg and DBP <80 mmHg (n=215); PHT: 130 mmHg≤SBP<140 mmHg and/or 80 mmHg≤DBP<90 mmHg (n=119); hypertensive (HT): SBP ≥140 mmHg and/or DBP ≥90 mmHg (n=292). Correlation analyses and comparisons were performed among the groups and in the cIMT subgroups (cIMT ≥0.050 cm and <0.050 cm). Results: cIMT and PWV-ES significantly differed among the BP groups (P<0.05). The BP groups had similar PWV-BS when cIMT <0.050 cm or cIMT ≥0.050 cm (all P>0.05). However, the NBP group had a notably lower PWV-ES than the PHT (P<0.001 and P=0.024) and HT (all P<0.001) groups in both cIMT categories, while the PWV-ES in the PHT group were not significantly lower than in the HT group (all P>0.05). Conclusion Carotid morphological and biomechanical properties in the PHT group differed from those in the NBP group. ufPWV could be used for an early evaluation of carotid stiffening linked to pre-hypertension.

Purpose: The present study investigated the association between Systematic COronary Risk Evaluation (SCORE)-estimated cardiovascular risk and carotid stiffening in a middle-aged population using ultrafast pulse wave velocity (ufPWV). Methods: This study enrolled 683 participants without known cardiovascular disease or diabetes mellitus who underwent ufPWV measurements. Clinical interviews, physical examinations, laboratory findings, carotid intima-media thickness (cIMT), pulse wave velocity (PWV) at the beginning of systole (PWV-BS), and PWV at the end of systole (PWV-ES) were assessed. Each participant underwent an assessment of SCORE risk based on major cardiovascular risk factors (CVRFs), including age, sex, smoking, systolic blood pressure (SBP), and total cholesterol (TC). Crude and adjusted odds ratios (ORs) with 95% confidence intervals and ordinal logistic regression were used. Overall CVRFs were adjusted to assess ORs. Results: cIMT and carotid stiffening in PWV-BS and PWV-ES were significantly different between sex subgroups (all P<0.05), but only PWV-ES increased gradually in age and SCORE-estimated risk subgroups (all P<0.05). Compared with cIMT (r=0.388, P<0.001) and PWV-BS (r=0.159, P<0.001), PWV-ES was more strongly correlated with SCORE categories (r=0.405, P<0.001). Higher PWV-ES values were associated with SCORE categories independently of sex, SBP, TC, and smoking in moderate-risk and high-risk subgroups (OR, 1.63; P<0.001 and OR, 2.12; P=0.024, respectively), but were not independent of age in all risk subgroups (all P>0.05). Conclusion Carotid stiffening quantified by ufPWV is linked to SCORE categories, and elevated PWV-ES may aid in cardiovascular risk stratification.

Objective:To explore the clinical effect of Pingchuan Decoction combined with routine western medicine therapy in the treatment of acute attack of bronchial asthma in children. Methods:From January 2017 to June 2019, 118 children with acute attack of bronchial asthma were selected from the Seventh People’s Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and they were randomly divided into control group (59 cases) and observation group (59 cases) according to the random number table. The control group was treated with routine western medicine therapy, and the observation group was treated with Pingchuan Decoction on the base of control group, and both groups were treated for 14 days. The main symptom scores before and after treatment were evaluated. The percentage of forced vital capacity expressed as percent predicted (FVC% pred) and the forced expiratory volume in 1 second expressed as percent predicted (FEV1% pred) were measured by pulmonary function meter. The levels of CD3 +, CD4 + and CD4 +/CD8 + in peripheral blood were detected by flow cytometry. The adverse reactions during the treatment were recorded and the clinical efficacy was evaluated. Results:The total clinical effective rate was 93.2% (55/59) in the observation group and 71.2% (42/59) in the control group, where the difference between the two groups was statistically significant ( χ2=9.790, P=0.002). After treatment, the scores of cough, wheezing and wheezing rale in the observation group were significantly lower than those in the control group ( t=27.695, 17.573, 32.827, P<0.001). After treatment, FVC% pred [(80.21 ± 4.06)% vs. (71.71 ± 3.95)%, t=11.526], FEV1% pred [(78.84±3.92)% vs. (72.26 ± 3.59)%, t=9.508] in the observation group were significantly higher than those in the control group ( P<0.01). The levels of CD3 + [(74.05 ± 5.13)% vs. (67.44 ± 4.98)%, t=7.101], CD4 + [(48.43 ± 4.31)% vs. (42.20 ± 4.06)%, t=8.082] and the ratio of CD4 +/CD8 + (1.67 ± 0.29 vs. 1.34 ± 0.25, t=6.620) in the observation group were significantly higher than those in the control group ( P<0.01). During the treatment, the incidence of adverse reactions was 10.2% (6/59) in the observation group and 6.8% (4/59) in the control group, and there was no significant difference between the two groups ( χ2=0.437, P=0.509). Conclusion:The Pingchuan Decoction combined with routine western medicine therapy can reduce the clinical symptoms of children with acute attack of bronchial asthma, improve lung function, improve organism immunity and clinical effect with safety.

Objective:To find out the occurrence of anxiety and depressive symptoms, and the major risk factors, and the participation rate, as well as the experience of medical personnel who are involved in the intervention.Methods:Since January 2018, a pilot intervention had been carried out on pregnant women registered in the antenatal clinic. The Generalized Anxiety Disorder Scale and the Patient Health Questionnaires were used as screening tools for anxiety and depression symptoms, and risk factors were screened too. Interventions were carried out on the psychological moderate and high risk women by obstetric medical staff and mental health personnel. A qualitative interview was conducted on the intervention providers.Results:A total of 9 488 pregnant women were included, and the positive rate of moderate anxiety symptoms was 3.0%, the positive rate of severe anxiety symptoms was 1.4%; the positive rate of moderate depression symptoms was 18.1%, and the positive rate of severe depressive symptoms was 5.2%; the comorbidity rate of anxiety and depression symptoms was 3.4%. The first three risk factors for pregnant women with anxiety symptoms were: once had premenstrual stress symptom, excessive fear of fetal growth, previous abnormal maternal history; the first three risk factors for pregnant women with depressive symptoms: once had premenstrual stress symptom, previous abnormal maternal history, this pregnancy was cherished; the first three risk factors for pregnant women with moderate and above anxiety combined with depression were: once had premenstrual stress symptom, excessive fear of fetal growth, and fear the delivery process is not successful. Among the psychological moderate risk pregnant women, 19.1% participated in the midwife joint counselor clinic, and 1.7% participated in the obstetrician joint psychological specialist nurse clinic, 2.2% of the pregnant women with high risk participated in the psychological multidisciplinary consultation, and 1.7% referred to the psychiatric department. From the interviews, providers believed that it was necessary to further strengthen the ability of psychological intervention capacity, and the psychological screening tools needed to be improved, and the problems sought by pregnant women involved in physical, psychological and social aspects, and the influence of pregnant women's treatment compliance included multiple factors.Conclusions:The psychological health care service during pregnancy was feasible, but the screening scales needed further examination. The mental health care ability of obstetric medical staff needed to be strengthened, and the compliance of pregnant women with mental health services needed to be improved.

Proteins presence and differences of the expression level can clarify the physiological or pathological changes in organisms;so the quantitative detection of proteins is vital for disease mechanism research;diagnosis and prognosis evaluation.Traditional protein quantitation methods at the tissue level reflected the average protein expression in cells;but ignore the differences between individual cells.In contrast;approaches for quantitative detection at single-cell level can better reflect the differences.Recently;a number of approaches for such detec-tion have been proposed;including microfluidics;microwell-based technology;optical fiber nanobiosensor;activity-based probe technology and mass spectrometry.The principles;advantages and drawbacks of these approaches are briefly introduced in this review.
