Objective:To develop a prediction model using machine learning to identify anxiety and depression in elderly individuals.Methods:This study collected data from 15079 elderly individuals in Shanxi Province, including their social demographic factors and disease status.Anxiety and depression were evaluated using GAD-7 and PHQ-9 scales to understand the characteristics of mental illness in the elderly.The evaluation indexes included accuracy, recall, precision, F1 score, Receiver Operating Characteristic Curve(ROC), and area under the curve(AUC), which were derived from the confusion matrix and several models.Results:The output of our study clearly demonstrates that the full feature prediction based on LightGBM is highly accurate, with an AUC of 0.805[95% CI: 0.794-0.811]. This outperforms the Random Forest model, which achieved an AUC of 0.730[95% CI: 0.702-0.741], and the XGboost model, which achieved an AUC of 0.802[95% CI: 0.780-0.807]. Therefore, LightGBM algorithm proves to be a strong prediction model.Our simplified model, based on eight selected features, also achieves a respectable AUC of approximately 0.75. Conclusions:The new prediction model for anxiety and depression specifically designed for the elderly can be effectively utilized in grassroots health surveys or for self-examinations to efficiently predict anxiety and depression levels among the elderly population in the community.

Objective To investigate the predictive value of pre-treatment prognostic nutritional index (PNI) and nutrition-related indicators on the prognosis of patients with brain glioma. Methods The clinical data of 210 patients with brain glioma admitted to two hospitals in Yibin City from January 2015 to December 2020 were retrospectively collected, with the follow-up deadline on December 30, 2022. The receiver operating characteristic (ROC) curve was plotted to calculate the area under the curve (AUC) and the optimal cut-off value of each indicator for predicting patients′prognosis. The Kaplan-Meier method was used to plot the survival curve, and the influencing factors of prognosis of patients were explored through Log-rank test and multivariate Cox regression analysis. Results The average overall survival time of 210 patients was 21.8 months, and 140 patients (66.7%) died during the follow-up period, with a 1-year survival rate of 54.6%. ROC curve analysis results showed that the AUCs of albumin, prealbumin, lymphocytes, PNI, and body mass index for predicting the prognosis of patients with brain glioma were 0.856, 0.689, 0.833, 0.927, and 0.647, with the optimal cut-off values of 36.0 g/L, 205.0 mg/L, 1.85×10⁹/L, 46.5, and 21.0 kg/m², respectively. The results of multivariate Cox regression analysis showed that PNI, albumin, and World Health Organization (WHO) grading were all influencing factors for the prognosis of patients with brain glioma (P < 0.05). The survival curve analysis results showed that the 1-year survival rates of patients with PNI < 46.5 and PNI≥46.5 were 35.1% and 84.2%, respectively, were 35.8% and 74.3%, respectively in patients with albumin < 36.0 g/L and albumin ≥ 36.0 g/L, and were 90.2%, 55.2%, and 16.3%, respectively in patients with WHO grades of Ⅱ, Ⅲ, and Ⅳ. Conclusion The prognosis of patients with brain glioma is related to PNI, albumin, and WHO grading, and PNI has a high predictive value for the prognosis of patients with brain glioma.

Objective To explore the clinical effect of nursing intervention program based on social support and information motivation behavioral model for pregnant women with gestational diabetes mellitus(GDM).Methods A total of 104 pregnant women with GDM admitted to Linping District,the Second Affiliated Hospital of Zhejiang University School of Medicine from February 2020 to February 2022 were selected as study objects,and were divided into experimental group and control group by random number table method,with 52 cases in each group.The pregnant women in control group were given routine nursing intervention,and the pregnant women in experimental group were given social support and information motivation behavioral model nursing intervention based on routine nursing.The depression-anxiety-stress scale,disease cognition and health behavior,blood glucose control during pregnancy,perinatal maternal and infant complications and delivery mode were compared between two groups.Results After the intervention,the scores of depression,anxiety,stress,fasting blood glucose,2-hour postprandial blood glucose and glycosylated hemoglobin of pregnant women in experimental group were significantly lower than those in control group,and the scores of disease cognition,health promoting lifestyle profile and vaginal delivery rate were significantly higher than those in control group(P<0.05).The complication rate of pregnant women and perinatal infants in experimental group was significantly lower than that in control group(P<0.05).Conclusion The nursing intervention program based on social support and information motivation behavioral model has good effect on pregnant women with GDM,which can enable pregnant women to obtain more social support,reduce negative emotions,improve health behaviors,promote blood glucose control,and increase the rate of natural childbirth.

Objective:To examine the correlation between serum 25-hydroxyvitaminD [25(OH)D] levels and all-cause mortality risk among adult women in the United States.Methods:Data for this retrospective cohort study were obtained from the National Health and Nutrition Examination Survey 2011—2016. A total of 6 452 women with complete data were enrolled and the end point event was all-cause mortality. The subjects were categorized into four groups based on serum 25(OH)D levels: severe deficiency group [25(OH)D<25.0 nmol/L, n=285], deficiency group [25(OH)D 25.0-49.9 nmol/L, n=1 695], insufficient group [25(OH)D 50.0-74.9 nmol/L, n=2 119], and sufficient group [25(OH)D≥75.0 nmol/L, n=2 353]. The serum 25 (OH) D level was included in cox proportional hazards model as a continuous variables and a categorical variables, respectively, to estimate the risk of all-cause mortality. Cox regression model based on restricted cubic splines was used to observe the curve relationship between the continuous change of serum 25(OH)D and the risk of all-cause mortality. A two-piecewise linear regression model was used to analyze the saturation threshold effect and examine the correlation between serum 25(OH)D levels and all-cause mortality risk among adult women in the United States. Results:A total of 6 452 women were enrolled. The mean level of serum 25(OH)D was (68.2±31.6) nmol/L, and only 36.5% (2 353/6 452) of the women had sufficient vitamin D. During the follow-up time of (5.8±1.8) years, 375 women died, and the all-cause mortality rate of 5.8%. After multivariate adjustment, for every 10 nmol/L increase in serum 25(OH)D level, the risk of all-cause mortality was reduced by 5% ( HR=0.95, 95% CI: 0.91-0.98) ( P<0.05). Compared with serum 25(OH)D severe deficiency group, the risk of all-cause mortality in 25(OH)D sufficient group was 54% lower ( HR=0.46, 95% CI: 0.29-0.75) ( P<0.05, Ptrend<0.001). The association between serum 25(OH)D levels and all-cause mortality risk exhibited an L-shaped curve ( P=0.007) and the inflection point was 128.5 nmol/L; when the serum level of 25(OH)D was less than 128.5 nmol/L, for every 10 nmol/L increase in 25(OH)D, the risk of all-cause mortality was reduced by 8% ( HR=0.92, 95% CI: 0.88-0.96) ( P<0.001). Conclusion:High serum 25(OH)D concentrations are non-linearly associated with low risk of all-cause mortality. These findings suggest that maintaining adequate vitamin D status may lower mortality risk in American women individuals.

Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients, but currently available treatments are often ineffective. Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed. Rhodojaponin VI, a grayanotoxin from Rhododendron molle, showed remarkable antinociceptive efficacy in models of neuropathic pain, but its biotargets and mechanisms are unknown. Given the reversible action of rhodojaponin VI and the narrow range over which its structure can be modified, we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin VI. N-Ethylmaleimide-sensitive fusion (NSF) was confirmed as the key target of rhodojaponin VI through biological and biophysical experiments. Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca²⁺ current intensity, whereas rhodojaponin VI reversed the effects of NSF. In conclusion, rhodojaponin VI represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF.

Objective:To analyze the costs and effectiveness of five common screening modes and genetic screening for thalassemia in China in order to find the optimal way and provide evidence for the implementation of thalassemia prevention and control projects in Hunan Province.Methods:From June 2020 to April 2021, 12 971 couples from 14 cities and autonomous prefectures in Hunan Province were selected as the study population. The diagnosis of thalassemia was based on the results of genetic testing. Results of routine blood test and hemoglobin electrophoresis were collected and analyzed. The efficacy of five screening modes, at the cut-off value of <80 fl or 82 fl for the mean corpuscular volume (MCV), was analyzed by positive predictive value, negative predictive value, Jorden index and cost-effectiveness ratio. Sensitivity analysis was used to assess the feasibility of genetic screening at different costs after fixing the costs of routine blood and hemoglobin electrophoresis. The five thalassemia screening models are as follows: Mode 1: The woman had a blood routine test first. If the result was positive, the spouse required a blood routine test. If both results were positive, a thalassemia gene test should be offered to the couple. Mode 2: Both husband and wife were screened by blood routine and hemoglobin electrophoresis. If one or both of them were positive, both would be tested for thalassemia gene. Mode 3: The couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing. Mode 4: The woman was screened by blood routine and hemoglobin electrophoresis. If any one of them was positive, the woman would be tested for thalassemia gene. If the gene test result was positive, the spouse should receive thalassemia gene. Mode 5: Both spouses conducted a blood routine test. If either was positive, both would conduct hemoglobin electrophoresis test. If both were positive, both spouses should receive thalassemia gene testing. Gene testing mode: The woman would be tested for thalassemia, and her spouse would have thalassemia test too if her result was positive.Results:When using MCV<80 fl as the cut-off for diagnosing thalassemia, the Youden indices of the five prenatal screening modes in Hunan Province were 0.551, 0.639, 0.898, 0.555 and 0.356, while when using MCV<82 fl as the cut-off, the Youden indices were 0.549, 0.629, 0.851, 0.548 and 0.356. When the MCV cut-off value was <80 fl, the missed diagnosis rates of the five screening modes were 44.44%, 0.00, 0.00, 18.52% and 62.96%, and the cost-effectiveness ratios were 21 709, 250 939, 76 870, 138 463 and 92 860 yuan (RMB)/couple, respectively. When the price of genetic testing was lower than 55 yuan (RMB), the cost-effectiveness ratio of genetic screening was lower than that of Mode 3.Conclusions:MCV<80 fl can be considered as the positive criteria in blood routine screening for thalassemia in Hunan Province, and the cost-effectiveness ratio of Mode 3 (the couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing) is the best. Genetic screening has certain advantages with the decreasing price.

Objective:To investigate the application value of KARL iterative algorithm combined with low-dose CT scanning in young and middle-aged patients with femoral neck fractures.Methods:The clinical data of 132 young and middle-aged patients with femoral neck fractures diagnosed by clinical and CT scan in Taizhou Bo′ai Hospital from August 2019 to May 2022 were collected. There were 68 cases in the conventional dose group reconstructed by projection, and 64 cases in the low dose group reconstructed by KARL iterative algorithm. The subjective image quality score, the excellent and good rates and CT value, signal to noise ratio (SNR) were compared between the two groups. The effective dose (ED), CT dose index (CTDIvol), dose-length product (DLP) were compared between the two groups.Results:There were no significant differences in subjective image quality score, the excellent and good rates between the two groups ( P>0.05). There were no significant differences in CT values and SNR of the trabecular dense area at the central level of the femoral head, the iliopsoas muscle at the same level, and the anterior abdominal wall or buttocks subcutaneous fat at the same level between the two groups ( P>0.05). The levels of CTDIvol, DLP and ED in he low-dose group were lower than those in the conventional dose group: (3.35 ± 1.05) mGy vs. (12.90 ± 2.92) mGy, (66.33 ± 20.26) mGy/cm vs. (253.12 ± 58.57) mGy/cm, (0.99 ± 0.30) mSv vs. (3.79 ± 0.88) mSv, there were statistical differences ( P<0.05). Conclusions:Based on KARL iterative algorithm combined with low-dose CT scanning has no significant effect on the clinical diagnosis and classification of femoral neck fractures, the scanning image has a high objective evaluation value, and can effectively reduce the radiation dose received by patients, which is useful for clinical preoperative diagnosis and surgical planning.

Objective:To determine whether insulin resistance is associated with all-cause mortality in subjects without diabetes.Methods:A total of 505 participants without diabetes, 198 with normal glucose tolerance (NGT) and 307 with impaired glucose tolerance (IGT), were recruited from the Daqing Diabetes Study. The participants were followed up for 30 years. They were stratified into three groups (tertiles) according to baseline homeostasis model assessment of insulin resistance(HOMA-IR) levels, as the HOMA-IR 0, the HOMA-IR 1 and the HOMA-IR 2 groups, to assess the predictive effect of insulin resistance on risk of all-cause mortality.Results:During the 30-year follow-up, 52, 56 and 78 participants died across the three HOMA-IR groups, respectively. The corresponding mortality per 1 000 person-years (95 %CI) were 12.12 (9.56-15.01), 13.10 (10.46-16.03) and 19.91 (16.73-23.15), respectively. Participants in the HOMA-IR 2 group had a significantly higher risk of death than those in the HOMA-IR 0 group after adjustment of age, sex and smoking status ( HR=1.97,95 %CI 1.38-2.81, P<0.001). Cox analyses showed that a one standard deviation increase in HOMA-IR was associated with a 22% increase in the mortality after adjustment of potential confounders ( HR=1.22, 95 %CI 1.08-1.39, P=0.002). Conclusions:Insulin resistance is associated with increased risk of all-cause death in Chinese people without diabetes, suggesting that improving insulin resistance could be beneficial for people without diabetic in reducing risk of long-term all-cause mortality.
