ABSTRACT
@#Risk assessment models for periodontal disease provide dentists with a precise and consolidated evaluation of the prognosis of periodontitis, enabling the formulation of personalized treatment plans. Periodontal risk assessment systems have been widely applied in clinical practice and research. The application fields of periodontal risk assessment systems vary based on the distinctions between clinical periodontal parameters and risk factors. The assessment models listed below are commonly used in clinical practice, including the periodontal risk calculator (PRC), which is an individual-based periodontal risk assessment tool that collects both periodontal and systemic information for prediction; the periodontal assessment tool (PAT), which allows for quantitative differentiation of stages of periodontal disease; the periodontal risk assessment (PRA) and modified periodontal risk assessment (mPRA), which are easy to use; and the classification and regression trees (CART), which assess the periodontal prognosis based on a single affected tooth. Additionally, there are orthodontic-periodontal combined risk assessment systems and implant periapical risk assessment systems tailored for patients needing multidisciplinary treatment. This review focuses on the current application status of periodontal risk assessment systems.
ABSTRACT
Aiming at the hysteresis and destructiveness of off-line static detection of critical quality attribute of the moisture content of the raw material unit of the traditional Chinese medicine manufacturing process, honey-processed Tussilago farfara, honey-processed Astragalus and honey-processed Glycyrrhiza uralensis were used as the research carriers, and the drying method was used to measure the moisture content as a reference value. The moving stage was used to simulate the movement process of samples on the conveyor belt in the actual on-site production process, and near-infrared (NIR) spectra were collected, combined with machine learning, to establish NIR on-site dynamic detection model of moisture content in multi-variety honey-processed Chinese herbal slice. The results show that the second derivative method is used to preprocess the spectrum. The number of decision trees (ntree), the number of random features (max feature), and the minimum number of samples for generating leaf nodes (node size) are selected: 46, 76, and 8, respectively. The quantitative analysis model of moisture content has the best effect. The prediction coefficient of determination (the prediction coefficient of determination, R2pre) and the root mean square error of prediction (root mean square error of prediction, RMSEP) of the model were 0.903 2 and 0.330 2, respectively. The NIR quantitative model for the moisture content of multi-variety honey-processed Chinese herbal slice established in this study has good predictive performance, and can achieve rapid, accurate and non-destructive quantitative analysis of the moisture content of honey-processed Tussilago farfara, honey-processed Astragalus and honey-processed Glycyrrhiza uralensis at the same time, and provides a method for determining the moisture content of honey-processed Chinese herbal slice of the raw material unit of the traditional Chinese medicine manufacturing process.

ABSTRACT
【Objective】 To analyze the results of different methods for reactive samples screened by the enzyme linked immunosorbent assay (ELISA) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in blood donors. 【Methods】 From March to April 2020, a total of 8 632 blood samples in Shenzhen were screened for SARS-CoV-2 total antibodies (TAb, including IgG, IgM, IgA) in plasma using ELISA(PC group), the antibody reactivity samples and their follow up plasma samples (FC group), and samples of disease control group(DC group) from January to April 2020 were detected using the following methods: 1) ELISA method for detecting IgG, IgM, and (or without detection) TAb; 2) pseudovirus neutralizing antibody test(pVNT); 3) western blot (WB) of SARS-CoV-2 antibody. The negative control group(NC group) from February to April 2020 performed ELISA and WB testing. 【Results】 Among the 34 total antibody positive samples, 2 were positive for pVNT test, and the total antibody, IgG and WB in the initial screening and tracking testing were positive. Thereafter, it was determined to be confirmed positive. The other 2 cases were positive for pVNT test, while the samples with positive WB results were in the follow-up stage. The TAb, IgG, and pVNT results did not conform to the dynamic evolution of antibodies, and cannot be determined as confirmed positive. 【Conclusion】 The infection status of antibody reactivity samples screened by SARS-CoV-2 ELISA can be judged by the logic of pVNT, WB and the dynamic change of antibody.
ABSTRACT
@#Abstract: Objective To explore the dynamic characteristics of stigmatization in HIV/AIDS patients and provide scientific evidence for psychological care. Methods HIV/AIDS patients receiving antiretroviral therapy (ART) treatment in Nanning Fourth People's Hospital were randomly selected for baseline and 1 year follow-up questionnaire survey including internalized HIV stigma, anticipated HIV stigma, exposure to HIV stigma. The differences between the two groups at different time points were dynamically compared to analyze the changing characteristics of stigma in HIV/AIDS patients. Results After one year of ART treatment, among the eight items of internalizing stigma, five items including the proportion of feeling ashamed of being infected with HIV/AIDS, feeling unclean because of being infected with HIV/AIDS, feeling inferior to others because of having HIV/AIDS, feeling guilty because of having HIV/AIDS, and having a poorer self-perception due to how others view HIV/AIDS decreased significantly from 34.0% to 43.5% at the baseline to 19.5% to 29.5%, showing significant improvement with statistical significance (χ2=18.586, 14.277, 10.473, 12.219, 9.934, P<0.05); among the nine items of anticipated stigma, four items including the proportion of community/community workers not taking my needs seriously, discriminating against me, refusing to provide services for me, and healthcare workers avoiding contact with me decreased significantly from 16.0% to 27.5% at the baseline to 7.0% to 15.5%, respectively, showing significant improvement with statistical significance (χ2=13.690, 15.787, 12.034, 12.593, P<0.05); among the 16 items of exposure to HIV stigma, six items including the proportion of experiencing physical attacks, psychological pressure from spouses/partners, being refused sexual relationships, losing jobs or other economic sources, being rejected or losing a job opportunity due to HIV/AIDS, changing job nature due to HIV/AIDS, or being refused medical services decreased significantly from 2.5% to 15.0% at the baseline to 1.0% to 8.0%, respectively, showing significant improvement with statistical significance (χ2=8.619, 15.558, 6.061, 9.049, 5.432, 8.156, P<0.05). Physical assaults on people with HIV/AIDS increased by 5.5 percent(χ2=5.368, P<0.05). Conclusions Through 1-year dynamic monitoring, 48.48% of the three dimensions of stigma of HIV/AIDS patients were alleviated. Treatment intervention, self-acceptance and the creation of a good non-discriminatory social environment have an important impact on the stigma of HIV/AIDS patients and deserve the attention of society as a whole.
ABSTRACT
This data article presents data from the China Migrants Dynamic Survey (CMDS), a multi-wave, large-scale national cross-sectional survey of China's internal migrants from 2009 to 2018. The CMDS is an annual questionnaire survey conducted by the former National Health and Family Planning Commission (NHFPC) of the People's Republic of China. The respondents included in this survey are internal migrants over 15 years old. The sample was drawn from the China Migrant Population Information System, using multi-stage stratified sampling method and the probability proportional-to-size (PPS) cluster sampling strategy. Between 2009 and 2018, there were 1,527,650 internal migrants from 23 provinces, 5 autonomous regions and 4 municipalities participated in the surveys. The survey tools were a series of self-designed questionnaires with high inheritance and consistency designed and implemented by the NHFPC. The questionnaires mainly contain basic information of the respondents and their family members, migration status, healthcare or health behaviors, public health service utilization, social insurance, social integration, and family planning. The dataset is currently the most widely used survey data on China's internal migrants, offering information on migration patterns, healthcare and health behaviors, use of public health services, access to social security, social integration, and family planning, which are valuable for health planning, health decision-making, and health equity research.

ABSTRACT
Objective: To evaluate the prognostic value of kinetic changes in minimal residual disease (MRD) status, as well as its relationship with risk stratification, therapeutic response and treatment in patients with newly-diagnosed multiple myeloma (MM) . Methods: A total of 135 patients with newly-diagnosed MM were screened, and 105 patients who achieved VGPR or more as the best responses were included into this study. The MRD status was determined by multiparameter flow cytometry (MFC) at multiple intervals after two cycles of treatment until clinical relapse, death, or last follow-up. The statistical methods included Kaplan-Meier analysis, Cox regression, etc. Results: ①In all 135 patients, 57.8% (78/135) patients achieved MRD negativity (MRD(-)) after treatment. In 105 patients who achieved VGPR and thus included in this study, the MRD(-) rate was 72.4% (76/105) , with a median interval of 3 months from starting treatment to achievement of MRD(-) status. ②The 2-year PFS rate of patients with MRD(-) status was significantly higher than that of MRD(+) status (62.2% vs 41.3%, P=0.001) , while MRD persistence (MRD(+)) was an independent factor for poor prognosis (multivariate analysis for PFS: P=0.044, HR=3.039, 95%CI 1.029-8.974) . ③Loss of MRD(-) status (i.e., MRD reappearance) showed inferior outcomes compared with MRD sustained negative ones, the PFS was 18 months versus not reach (P<0.001) and the OS was not reach for both (P=0.002) . ④The 2-year PFS and OS rates of patients with duration of MRD(-)status≥12 months were significantly higher than those of the control group (PFS: 77.7% vs 36.7%, P<0.001; OS: 96.4% vs 57.9%, P<0.001 respectively) . Duration of MRD(-) status was associated with a marked reduction in risk of relapse or death (univariate analysis for PFS: P<0.001, HR=0.865, 95%CI 0.815-0.918; for OS: P=0.001, HR=0.850, 95%CI 0.741-0.915 respectively) . ⑤Moreover, even in patients carrying high-risk cytogenetic abnormalities (CA) or ineligible for ASCT, MRD negativity remained its prognostic value to predict PFS (high-risk CA medianPFS: not reach vs 19 months, P=0.006; ineligible for ASCT medianPFS: not reach vs 25 months, P=0.052 respectively) . ⑥Last, treatment with the bortezomib-based regimens contributed to prolonged MRD(-) duration (median MRD(-) duratio: 25 months vs 10 months, P=0.034) . Conclusion: Our findings supported MRD(+) status as an independent poor prognostic factor in MM patients, which implicated that duration of MRD(-) status also played a significant role in evaluation of prognosis, while loss of MRD(-)status might serve as an early biomarker for relapse. Therefore, monitoring of MRD kinetics might more precisely predict prognosis, as well as guide treatment decision, especially for when to start retreatment in relapsed patients.

Objective To investigate the influence of serum creatinine (sCr) at different time-points on prognosis of critically ill patients with acute kidney injury (AKI).Methods This study was retrospectively analyzed the clinical data of critical patients with AKI who admitted to the mixed ICU of Xiaolan Hospital of Southern Medical University during March 2015 and January 2016. According to the clinical prognosis, the patients were divided into the renal replacement therapy (RRT) group and non-renal replacement therapy (non-RRT) group, 28-day renal loss group and renal recover group, hospital death group and survival group. Serum Cr at different time-points and clinical data were collected. The receiver operating characteristic (ROC) curve and the area under curve (AUC) were used to evaluate the capability of sCr at different time-points in predicting clinical prognosis.Results During the study, 85 AKI patients were enrolled. The in-hospital mortality was 20％, RRT rate was 15.3％, and renal lose at 28 days after ICU admission was 31.8％. The levels of sCr out of ICU (o-sCr) and the peak of sCr were significantly higher in the RRT group than the non-RRT group (P<0.01). The o-sCr and p-sCr predicted RRT during the hospital stay with a higher AUC value (0.806vs 0.833) than b-sCr and a-sCr. The levels of b-sCr, a-sCr, o-sCr, and p-sCr were all significantly higher in the28-day renal loss group than the kidney recover group (P<0.01). The levels of o-sCr and p-sCr were significantly higher in the hospital death group than the survival group (P<0.05). The o-sCr predicted renal lose at 28 days and hospital death with the highest AUC value of 0.850 and 0.797, respectively.Conclusions It cannot be ignored to monitor dynamically the level of sCr at different time-points in critical patients with AKI, which can predict the clinical prognosis such as hospital death, RRT and renal lose at 28 days after ICU admission.

Objective To detect serum ubiquitin-like with PHD and ring finger domains 1 (UHRF1) levels in the patients with esophageal squamous cell carcinoma (ESCC),and analyze their differences among different clinicopathological features subgroups and changes during the perioperative period.Methods Serum samples from 130 preoperative ESCC patients,62 patients 1 week after operation,14 patients 1 week and 2 weeks after operation and 67 healthy controls,and clinicopathological data from ESCC patients were collected.Serum UHRF1 levels were detected by ELISA,and the differences among different groups were analyzed with independent t test,paired t test or one-way ANOVA.Results Serum UHRF1 levels in 130 preoperative ESCC patients were significantly higher than that in healthy controls (t =7.680,P ＜ 0.01),and they were related to the ESCC patients' tumor size,differentiation degree,tumor invasion,lymph nodes metastasis and pTNM stage (P ＜ 0.05),but unrelated to the patients' age,gender,tumor location and types (P ＞ 0.05).Serum UHRF1 levels in 62 postoperative patients were significantly lower than that before operation (t =5.530,P ＜ 0.01),but similar to that in healthy controls (t =1.622,P ＞ 0.05).The serum UHRF1 levels before operation,1 week after operation and 2 weeks after operation in 14 ESCC patients decreased gradually (F =7.595,P ＜ 0.01).Conclusion Serum UHRF1 levels may be a potential biomarker for dynamically monitoring perioperative ESCC patients.
ABSTRACT
Objective To explore the related factors on sore throat and pharyngeal xeransis during thyroid surgery.Methods Twenty-nine female patients, aged 24-67 years, BMI 18-30 kg/m2, falling into ASA physical status Ⅰ or Ⅱ, were scheduled for thyroid surgery.After anesthesia induction and tracheal intubation, the endotracheal intracuff was inflated to 20 mm Hg.Intracuff pressure was monitored every 5 minutes by a pressure transducer.At the time of 24 hours after tracheal intubation, the patients were asked about their throat complaints such as sore throat and pharyngeal xeransis.Results Endotracheal intracuff pressure during thyroid surgery was in a discrete distribution.Multiple linear regression model analysis found that age, BMI, anesthesia time and intracuff pressure had no obvious effects on sore throat.Decision tree model analysis found that patients undergoing thyroid surgery had higher probability of pharyngeal xeransis grade Ⅳ, when the average intracuff pressure was higher than 29 mm Hg.Conclusion Excessive endotracheal intracuff pressure during thyroid surgery due to operation causes pharyngeal xeransis.
ABSTRACT
The manufacture of traditional Chinese medicine (TCM) products is always accompanied by processing complex raw materials and real-time monitoring of the manufacturing process. In this study, we investigated different modeling strategies for the extraction process of licorice. Near-infrared spectra associate with the extraction time was used to detemine the states of the extraction processes. Three modeling approaches, i.e., principal component analysis (PCA), partial least squares regression (PLSR) and parallel factor analysis-PLSR (PARAFAC-PLSR), were adopted for the prediction of the real-time status of the process. The overall results indicated that PCA, PLSR and PARAFAC-PLSR can effectively detect the errors in the extraction procedure and predict the process trajectories, which has important significance for the monitoring and controlling of the extraction processes.
