BACKGROUND:At present,a large number of studies have found that Liuwei Dihuang Pill can be used to treat osteoporosis,but there are few related studies on the differentiation and mineralization of osteoblasts induced by wear particles using Liuwei Dihuang Pill. OBJECTIVE:To investigate the positive effect of different concentrations of Liuwei Dihuang Pill-containing serum on titanium particle-induced mouse MC3T3-E1 osteoblast in vitro osteolysis model. METHODS:Drug-containing serum was extracted after oral administration of Liuwei Dihuang Pill.The best concentration of Liuwei Dihuang Pill-containing serum and titanium particles on the viability of MC3T3-E1 cells was screened.MC3T3-E1 cells were divided into three groups.The blank group was given osteoblastic differentiation culture.The model group was given titanium particles(5 μg/mL)ossification culture.The drug-containing serum group was given titanium particles(5 μg/mL)+ Liuwei Dihuang Pill-containing serum(10%,15%and 20%doses).Osteoblast viability was detected by CCK-8 assay.Cell alkaline phosphatase activity was detected by alkaline phosphatase staining.Cell mineralization was detected by silver nitrate(Von Kossa)and alizarin red staining.Expression levels of bone differentiation-related genes Runx-2,Osterix,Ocn,Axin,Alp,and Opn were detected by qRT-PCR.Wnt/β-catenin signaling pathways β-catenin,p-GSK-3β,GSK-3β,Runx2 and Osterix protein expression levels were detected by western blot assay. RESULTS AND CONCLUSION:(1)Liuwei Dihuang Pill-containing serum culture reversed the decrease in alkaline phosphatase activity of MC3T3E-1 cells induced by titanium particles,increased the alizarin red staining and calcification of MC3T3E-1 cells,increased the expression of osteogenesis-related genes in MC3T3E-1 cells,and increased the expression of proteins related to the Wnt/β-catenin signaling pathway.(2)These findings indicate that Liuwei Dihuang Pill-containing serum can reverse the inhibitory effect of titanium particles on the differentiation and mineralization of osteoblasts,upregulate the expression of osteogenesis-related genes,and its mechanism is related to the regulation of Wnt/β-catenin signaling pathway,suggesting that Liuwei Dihuang Pill is expected to become an effective drug for preventing aseptic loosening of artificial joints.

Objective:To explore the relationship between metabolic score for insulin resistance (METS-IR) and chronic kidney disease (CKD) and albuminuria in the Chinese population.Methods:This cross-sectional study was conducted from January to December 2018 among residents aged 20 to 70 years in ten regions of eight provinces in China; all residents had lived in their region for more than 5 years. Various parameters were measured, included fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin (HbA 1c), blood lipids, renal function, urinary albumin/creatinine ratio (UACR), etc. Data of 5 060 subjects meeting the criteria were included in the study. CKD was defined as estimated glomerular filtration rate (eGFR)<60 ml·min -1·1.73 m -2 or UACR≥30 mg/g. Albuminuria was defined as UACR≥30 mg/g. METS-IR was calculated and categorized into quartiles: Q1, METS-IR≤32.19; Q2, METS-IR 32.20-37.10; Q3, METS-IR 37.11-42.58; and Q4, METS-IR>42.58. The correlation between METS-IR and CKD and albuminuria was analyzed by binary logistic regression, and subgroup analyses were performed. Results:There were 1 266, 1 266, 1 265, and 1 263 participants included in Q1-Q4 groups, respectively. With the increase of METS-IR quartile, various parameters increased, including age, fasting blood glucose, HbA 1c, triglycerides, serum uric acid, waist circumference, body mass index, and systolic and diastolic blood pressure, and the proportion of males also increased (all P<0.05). The proportion of patients with CKD and albuminuria increased significantly with the increase in interquartile range (Q) of METS-IR (all P<0.05). Logistic regression analysis showed that for every 1-unit increment of METS-IR, the risk of CKD and albuminuria were both increased by 2% [for both: odds ratio ( OR)=1.02, 95% confidence interval ( CI) 1.01-1.03]. Compared with the lowest METS-IR group (Q1), the ORs for CKD and albuminuria in the highest METS-IR group (Q4) were 1.57 (95% CI 1.17-2.10) and 1.46 (95% CI 1.09-1.96), respectively. In the subgroup analyses, increased METS-IR was significantly associated with CKD and albuminuria among women (CKD: OR=1.62, 95% CI 1.14-2.31; albuminuria: OR=1.53, 95% CI 1.07-2.18), individuals with HbA 1c<7% ( OR=1.64, 95% CI 1.21-2.23; OR=1.55, 95% CI 1.14-2.11), individuals with eGFR≥90 ml·min -1·1.73 m -2 ( OR=1.78, 95% CI 1.27-2.49; OR=1.80, 95% CI 1.28-2.53), and the Chinese Han population ( OR=1.56, 95% CI 1.13-2.17; OR=1.41, 95% CI 1.01-1.96). Conclusions:METS-IR is significantly associated with CKD and albuminuria in a Chinese population. Furthermore, the higher the METS-IR, the higher the risk of CKD and albuminuria.

Objective:
To analyze the neglect status of children aged 3-6 years old from non-only-child families in Beijing-Tianjin-Hebei region and influencing factors, so as to provide assistance for the healthy growth of preschool children from non-only-child families.
Methods:
From April to June 2022, 2 882 parents of preschool children from 15 kindergartens were selected in urban areas of Beijing-Tianjin-Hebei by randomized cluster sampling method, and were investigated with general information and neglect experiences. The χ 2 test, t-test and ANOVA were used to compare the neglect status of different categories of preschool children, and the binary Logistic regression method was used to analyze the influencing factors of the neglect of preschool children who were not only children.
Results:
The detection rate of neglect among children aged 3-6 years from non-only-child families in the Beijing-Tianjin-Hebei region was 33.47%, the detection rate of neglect among children from only-child families was 9.24%, and the difference was statistically significant ( χ 2=261.94, P <0.01). The neglect score for children aged 3-6 years in non-only-child families was (42.35±7.52), the neglect score for onechild families was (38.16±6.56), and the difference was also statistically significant ( t=15.95, P <0.01). Binary Logistic regression analysis showed that family income <4 000 yuan/month ( OR= 2.75, 95%CI =1.18-6.32), grandparents or other relatives as the primary guardian ( OR=2.18, 95%CI =1.35-3.52), and poor parental relationship ( OR=2.64, 95%CI =1.42-3.87), average ( OR=2.31, 95%CI =1.32-4.01) non-only-child preschoolers had a higher risk of neglect ( P <0.05).
Conclusion
Neglect is prevalent among 3-to 6-year-old children from non-only-child families in the Beijing-Tianjin-Hebei region. Targeted intervention measures based on influencing factors should be taken to reduce neglect among preschool children.

Background:
Creatinine-to-cystatin C ratio is recently suggested to be a surrogate marker for sarcopenia. However, little is known about its association with diabetes. This study aimed to fill in this gap based on a large-scale prospective cohort.
Methods:
A population-based representative sample of 5,055 participants aged ≥45 years from the China Health and Retirement Longitudinal Study was enrolled between 2011 and 2012 and followed at least once during the subsequent surveys at 2013, 2015, or 2018. Creatinine-to-cystatin C ratio was calculated and normalized by body weight. Incident diabetes was ascertained by plasma glucose, glycosylated hemoglobin, self-reported history, or use of anti-diabetic drugs. Logistic regression analysis and mediation analysis were employed.
Results:
During follow-up, 634 participants developed diabetes. The risk of diabetes was gradually and significantly decreased with increased normalized creatinine–cystatin C ratio. The multivariable-adjusted odds ratio for diabetes was 0.91 (95% confidence interval, 0.83 to 0.99) per 1 standard deviation higher of normalized creatinine-to-cystatin C ratio, and this relationship remained significant after controlling for muscle strength. The risk reduction in diabetes was significantly larger in participants with normal-weight and high normalized creatinine-to-cystatin C ratio compared with those with overweight/obesity and high normalized creatinine-to-cystatin C ratio (Pinteraction=0.01). Insulin resistance and inflammation appeared to be key mediators accounting for the observed relationship between normalized creatinine-to-cystatin C ratio and risk of diabetes, with their mediating effect being 93.1% and 22.0%, respectively.
Conclusion
High normalized creatinine-to-cystatin C ratio is associated with reduced risk of diabetes in middle-aged and older adults.

Idiopathic hypoparathyroidism is a rare endocrine disease. It is often manifested as neuropsychiatric symptoms, especially epileptic seizures. Thus, it is easy to be misdiagnosed as primary epilepsy. The following case report details the diagnosis of a 17-year-old girl who had been misdiagnosed as primary epilepsy for a long time. She was found hypoparathyroidism during the hospitalization for the operation of ovarian mixed germ cell tumor. After whole exome sequencing, she was ultimately diagnosed as 22q11.2 deletion syndrome. This case suggested that clinicians should be aware of the possibility of hypoparathyroidism in adolescent epilepsy, especially hereditary hypoparathyroidism. At the same time, the possible high risk of tumors should also be considered in hereditary hypoparathyroidism.

ObjectiveTo analyze the mental health status of non-psychiatric inpatients in a general hospital, and to explore the relevant influencing factors, so as to provide references for the screening of mental health problems and the construction of intervention models among non-psychiatric inpatients. MethodsA cross-sectional study was conducted among 916 non-psychiatric inpatients in a third grade class A general hospital in Guangzhou, and all the inpatients were assessed using Patient Health Questionnaire-9 item (PHQ-9), Generalized Anxiety Disorder-7 item (GAD-7), Athens Insomnia Scale (AIS) and Columbia-Suicide Severity Rating Scale (C-SSRS) to detect their depression, anxiety, insomnia and suicide risk status. Thereafter, univariate and multivariate Logistic regression analysis were used to screen the risk factors affecting the mental health of inpatients. ResultsA total of 339 (37.0%) inpatients with positive mental health problems were screened, and the screening results for each dimension revealed 218 cases (23.8%) of depression, 141 cases (15.4%) of anxiety, 257 cases (28.1%) of insomnia, 42 cases (4.6%) of suicidal ideation and 7 cases (0.8%) of suicidal behavior. Binary Logistic regression analysis showed that female (OR=1.379, P<0.05) was a risk factor for positive screening of mental health problems. Ordinal Logistic regression analysis denoted that age above 60 years old (OR=1.542, P<0.05) and singlehood (OR=2.055, P<0.05) were risk factors affecting the severity of depression, while senior high school to junior college education (OR=0.524, P<0.05) was a protective factor of depression, meantime, female (OR=1.472, P<0.05) was a risk factor affecting the severity of insomnia. ConclusionMental health problems are quite common among non-psychiatric inpatients in general hospitals, and are mainly affected by factors such as gender, age, marital status and educational background.

Objective To study the underlying mechanisms through which uric acid upregulates local renin-angiotensin system in adipocytes. Methods The primary cultured rat adipocytes were administered with 0, 1, 5, 10, and 15 mg/dl uric acid for 0, 12, 24, 48, and 72 h. Some of the pre-adipocytes were infected with siRNA-TLR2 or its negative control before differentiation. Then infected mature adipocytes were treated with 10 mg/dl uric acid for 48 h. After that procedure, mRNA levels of TLR2, TNF-α, IL-6, MCP-1, AGT, ACE1, AT1R, and AT2R were detected with real-time PCR method. The protein levels of TLR2 and NF-κB were detected by Western blotting. The concentrations of angiotensinⅡ( Ang Ⅱ) in the conditioned medium or cell lysate were measured using ELISA method. Results The mRNA levels mRNA of TLR2 increased in parallel with uric acid concentration. Moreover, it also increased with the time. By contrast, TLR2 mRNA expression decreased at 72 h. Uric acid increased levels of TNF-α, IL-6, and MCP-1 in adipocytes. It was also found that uric acid upregulated RAS components, including AGT, ACE1, AT1R, AT2R, and AngⅡ. However, siRNA-TLR2 infection significantly reduced the levels of TLR2 and NF-κB. As a result, both inflammatory cytokines and RAS components were significantly decreased in adipocytes. Conclusion Uric acid up-regulates RAS expression partially via TLR2 inflammatory signaling pathway in adipocytes.
