Relationship between preoperative psychological stress and short-term prognosis in elderly patients with femoral neck fracture.

BACKGROUND: Older adults are at high risk of femoral neck fractures (FNFs). Elderly patients face and adapt to significant psychological burdens, resulting in different degrees of psychological stress response. Total hip replacement is the preferred treatment for FNF in elderly patients; however, some patients have poor postoperative prognoses, and the underlying mechanism is unknown. We speculated that the postoperative prognosis of elderly patients with FNF may be related to preoperative psychological stress. AIM: To explore the relationship between preoperative psychological stress and the short-term prognosis of elderly patients with FNF. METHODS: In this retrospective analysis, the baseline data, preoperative 90-item Symptom Checklist score, and Harris score within 6 months of surgery of 120 elderly patients with FNF who underwent total hip arthroplasty were collected. We analyzed the indicators of poor short-term postoperative prognosis and the ability of the indicators to predict poor prognosis and compared the correlation between the indicators and the Harris score. RESULTS: Anxiety, depression, garden classification of FNF, cause of fracture, FNF reduction quality, and length of hospital stay were independent influencing factors for poor short-term postoperative prognoses in elderly patients with FNF (P < 0.05). The areas under the curve for anxiety, depression, and length of hospital stay were 0.742, 0.854, and 0.749, respectively. The sensitivities of anxiety, depression, garden classification of FNF, and prediction of the cause of fracture were 0.857, 0.786, 0.821, and 0.821, respectively. The specificities of depression, FNF quality reduction, and length of hospital stay were the highest at 0.880, 0.783, and 0.761, respectively. Anxiety, depression, and somatization scores correlated moderately with Harris scores (r = -0.523, -0.625, and -0.554; all P < 0.001). CONCLUSION: Preoperative anxiety, depression, and somatization are correlated with poor short-term prognosis in elderly patients with FNF and warrant consideration.

A Traditional Chinese Medicine for the Treatment of Endometrial Hyperplasia via Regulating the HPO Axis in Rats.

Dysfunctional uterine bleeding, accompanied by endometrial hyperplasia (EH), is a common gynecological disease that seriously affects female physical and mental health. Some drugs have been prompted to cure the disease, but most medications have certain side effects and limitations. In the present study, we demonstrated an unexploited Chinese traditional medicine, a combination of Saururus chinensis, Celosia cristata, and Spatholobus suberectus (SCS), which could be used for the treatment of EH and associated complications in rats. We identified the active components from the three Chinese herbs via thin-layer chromatography and high-performance liquid chromatography methods. In addition, serum biochemical indexes and histologic section results found that acute high-dose SCS exerted no adverse impacts on the rats. We then showed that SCS shortened coagulation time (p=0.018) and degree of swelling (p=0.021) on rats at 30 min compared to blank control. Further studies proved that recovered endometrial thickness was associated with the modulation of four hormones (follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone). Specifically, follicle-stimulating hormone and progesterone contents increased gradually with time, and estrogen was decreased, whereas luteinizing hormone content was returned to normal after a short-term elevation (p < 0.05). Besides, SCS increased uterine endometrium's mRNA expression levels of matrix metalloproteinase-1 (p < 0.001) and tissue inhibitor of matrix metalloproteinase-1 (p < 0.001), promoting the repair of proliferating endometrium in the rats. Collectively, our study indicates that SCS harbors a profoundly curative effect on the treatment of EH and relative complications and uncovers the mechanism at molecular and gene expression levels.

Dietary patterns and their associations with the metabolic syndrome and predicted 10-year risk of CVD in northwest Chinese adults.

The impact of diet on the metabolic syndrome (MetS) and CVD has been investigated widely, but few studies have investigated the association between dietary patterns (DP) and the predicted CVD, derived from reduced rank regression (RRR). The objectives of this study were to derive DP using RRR and principal component analysis (PCA) and investigate their associations with the MetS and estimated 10-year atherosclerotic CVD (ASCVD). We used the baseline dataset from the Xinjiang multi-ethnic cohort study in China, collected from June 2018 to May 2019. A total of 14 982 subjects aged 35-74 years from Urumqi, Huo Cheng and Mo Yu were included in the analysis. The 10-year ASCVD risk was estimated using the Chinese ASCVD risk equations. The associations of DP with the MetS and 10-year ASCVD were determined using multivariable logistic regression models. In Urumqi and Mo Yu, the increased RRR DP score was associated with a higher OR of having the MetS and with a higher OR of elevated 10-year ASCVD risk. However, only the first DP determined by PCA in Urumqi was inversely associated with the MetS and elevated 10-year ASCVD risk. The prevalence of the MetS and elevated ASCVD risk in urban population is higher than that in rural areas. Our results may help nutritionists develop more targeted dietary strategies to prevent the MetS and ASCVD in different regions in China.

Mathematical analysis and simulation of a Hepatitis B model with time delay: A case study for Xinjiang, China.

The incubation period for Hepatitis B virus (HBV) within the human is epidemiologically significant because it is typically of long duration (1.5∼6 months) and the disease transmission possibility may be increased due to more contact from the patients in this period. In this paper, we investigate an SEICRV epidemic model with time delay to research the transmission dynamics of Hepatitis B disease. The basic reproductive number ${\mathcal R}_0$ is derived and can determine the dynamics of the model. The disease-free equilibrium is globally asymptotically stable if ${\mathcal R}_0<1 and="" unstable="" if="" mathcal="" r="" _0="">1$. As ${\mathcal R}_0>1$, the model admits a unique endemic equilibrium which is locally asymptotically stable. The endemic equilibrium is globally asymptotically stable when the vertical transmission is ignored. Numerically, we study the Hepatitis B transmission case in Xinjiang, China. Using the Hepatitis B data from Xinjiang, the basic reproductive number is estimated as 1.47 (95% CI: 1.34-1.50). By the end of 2028, the cumulative number of Hepatitis B cases in Xinjiang will be estimated about 700,000 if there is no more effective preventive measures. The sensitivity analysis of ${\mathcal R}_0$ in terms of parameters indicates prevention and treatment for chronic patients are key measures in controlling the spread of Hepatitis B in Xinjiang.
