Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective:To explore the turnover intention of dental outpatient nurses, and analyze its influencing factors.Methods:From August to September 2021, multi-stage sampling was used to select nurses from 20 stomatology hospitals in 7 geographical regions of North China, East China, South China, Central China, Southwest, Northeast, and Northwest China. The survey was conducted using the General Information Questionnaire, Turnover Intention Scale, Nursing Work Environment Scale, Psychological Capital Scale for Nurses, and Work Engagement Scale.Results:A total of 1 513 questionnaires were collected, including 1 135 valid questionnaires, with a valid rate of 75.02% (1 135/1 513). The total score of turnover intention among 1 135 dental outpatient nurses was (2.22±0.56). Pearson correlation analysis showed a negative correlation between nursing work environment, psychological capital, work engagement, and turnover intention ( r=-0.421, -0.340, -0.446; P<0.01). The structural equation model showed that the nursing work environment had a direct negative effect on the turnover intention of dental outpatient nurses (β=-0.401, P<0.01) and had an indirect negative effect on turnover intention through work engagement (β=-0.106, P<0.01), with a mediating effect of 20.91%. Psychological capital had an indirect negative effect on the turnover intention of dental outpatient nurses through work engagement (β=-0.271, P<0.01), with a mediating effect of 52.83%. Conclusions:The turnover intention of dental outpatient nurses is at a high level. Managers can reduce the turnover intention of dental clinic nurses by improving the nursing work environment, developing psychological capital, and increasing work engagement.

Objective:To investigate which indicator is more advantageous when using arterial oxygen saturation(SaO2)and fingertip pulse oxygen saturation(SpO2)for blood oxygen detection in patients with hyperleukocytic acute leukemia(HAL).Methods:In this prospective research,the difference between SaO2 and SpO2 of 18 HAL patients(observation group)and 14 patients(control group),as well as the relationship between the difference and white blood cell(WBC)counts were analyzed.Results:SaO2 was lower than SpO2 in the observation group(P＜0.05),and SpO2-SaO2 difference was positively correlated with WBC counts(r=0.47).However,there was no statistical difference between SaO2 and SpO2 in the control group.SaO2 and PO2 showed a downward trend with the prolongation of detection time after arterial blood was collected in the observation group,but there was no statistical difference.There was no downward trend of SaO2 and PO2 in the control group.Conclusion:HAL patients have a phenomenon where SaO2 is lower than SpO2,that is pseudohypoxemia,and this phenomenon may be caused by excessive consumption of oxygen by the leukemia cells in vitro.SpO2 can be monitored bedside in real time and is non-invasive,it is a better way to detect the blood oxygen status of HAL patients.

Malignant tumors have become the main cause of human death.With the prolonged use of chemotherapeutic drugs during the treatment process,tumor cell resistance is also constantly increasing.long non-coding RNA(lncRNA)is an important mem-ber of the non-coding RNA family.Cancer susceptibility candidate 2(CASC2)is a type of long non-coding RNA,high expression of CASC2 can inhibit tumor cell development and reduce drug resistance of tumor cells by promoting apoptosis,regulating signaling path-ways,participating in cellular transmission pathways,competitively binding of miRNA,and changing the protein structure or functional status.This article will provide a comprehensive review of the regulatory effects and mechanism of lncRNA CASC2 on chemotherapy resistance in malignant tumors.

Objective:To explore the core prescriptions and mechanism of national TCM master Liu Bailing in the treatment of lumbar disc herniation (LDH) based on data mining and network pharmacology methods; To provide the clinical reference for the treatment of LDH.Methods:The cases of LDH treated by Professor Liu in Affiliated Hospital of Changchun University of Chinese Medicine, from January 1, 2011 to December 31, 2019 were collected and analyzed. Hierarchical clustering and association rules were used to analyze the medication rules and core prescriptions. TCMSP, GeneCards, ETCM, SymMap, DAVID, etc. were used to analyze the network pharmacology of the core compounds in treating LDH and symptoms, and reveal the mechanism.Results:A total of 1 334 prescriptions were included, involving 201 kinds of Chinese materia medica, among which the medicinal property was mainly warm, the flavor was mainly sweet and the meridians were mainly liver meridian and kidney meridian; the core medicines for the treatment of LDH included Aconiti Lateralis Radix Praeparata, Spatholobi Caulis, Cinnamomi Cortex, Corydalis Rhizoma, Eucommiae Cortex, Paederia Foetida and Amomi Fructus, reflecting that Professor Liu Bailing often treats LDH from the perspective of kidney deficiency, and commonly uses the treatment methods of dispelling wind, relieving pain, warming yang and benefiting the kidney. The core prescriptions mainly participated in three pathways of cancer, immunity and cell metabolism, including PI3K-Akt signaling pathway, TNF signaling pathway and FoxO signaling pathway. Conclusion:Professor Liu Bailing's treatment of LDH focuses on overall dialectical treatment, which mainly dispels wind, relieves pain, warms yang and benefits the kidney and the mechanism of the core prescriptions may lie in diminishing the inflammatory response. The core prescriptions may treat LDH by regulating the immune response and cellular physiological functions.

Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.

Chronic heart failure(CHF) is a series of clinical syndromes in which various heart diseases progress to their end stage. Its morbidity and mortality are increasing year by year, which seriously threatens people's life and health. The diseases causing CHF are complex and varied, such as coronary heart disease, hypertension, diabetes, cardiomyopathy and so on. It is of great significance to establish animal models of CHF according to different etiologies to explore the pathogenesis of CHF and develop drugs to prevent and treat CHF induced by different diseases. Therefore, based on the classification of the etiology of CHF, this paper summarizes the animal models of CHF widely used in recent 10 years, and the application of these animal models in traditional Chinese medicine(TCM) research, in order to provide ideas and strategies for studying the pathogenesis and treatment of CHF, and provide ideas for TCM modernization research.

The purpose of this study is to investigate whether chrysin reduces cerebral ischemia-reperfusion injury(CIRI) by inhi-biting ferroptosis in rats. Male SD rats were randomly divided into a sham group, a model group, high-, medium-, and low-dose chrysin groups(200, 100, and 50 mg·kg~(-1)), and a positive drug group(Ginaton, 21.6 mg·kg~(-1)). The CIRI model was induced in rats by transient middle cerebral artery occlusion(tMCAO). The indexes were evaluated and the samples were taken 24 h after the operation. The neurological deficit score was used to detect neurological function. The 2,3,5-triphenyl tetrazolium chloride(TTC) staining was used to detect the cerebral infarction area. Hematoxylin-eosin(HE) staining and Nissl staining were used to observe the morphological structure of brain tissues. Prussian blue staining was used to observe the iron accumulation in the brain. Total iron, lipid pero-xide, and malondialdehyde in serum and brain tissues were detected by biochemical reagents. Real-time quantitative polymerase chain reaction(RT-qPCR), immunohistochemistry, and Western blot were used to detect mRNA and protein expression of solute carrier fa-mily 7 member 11(SLC7A11), transferrin receptor 1(TFR1), glutathione peroxidase 4(GPX4), acyl-CoA synthetase long chain family member 4(ACSL4), and prostaglandin-endoperoxide synthase 2(PTGS2) in brain tissues. Compared with the model group, the groups with drug intervention showed restored neurological function, decreased cerebral infarction rate, and alleviated pathological changes. The low-dose chrysin group was selected as the optimal dosing group. Compared with the model group, the chrysin groups showed reduced content of total iron, lipid peroxide, and malondialdehyde in brain tissues and serum, increased mRNA and protein expression levels of SLC7A11 and GPX4, and decreased mRNA and protein expression levels of TFR1, PTGS2, and ACSL4. Chrysin may regulate iron metabolism via regulating the related targets of ferroptosis and inhibit neuronal ferroptosis induced by CIRI.

Objective:To analyze the clinical features and magnetic resonance imaging of non-malignant patients assigned to Prostate Imaging Reporting And Data System (PI-RADS) 5 score.Methods:We performed a retrospective review of 289 patients who underwent magnetic resonance ultrasound targeted combined system biopsy with PI-RADS 5 lesions in the First Affiliated Hospital of Nanjing Medical University between May 2019 and July 2021. The median age 72 (66, 77)years, median body mass index 24.4(22.3, 27.1)kg/m 2, median prostate volume (PV) 37.39(29.39, 48.86) ml, median PSA 22.24(10.91, 62.69) ng/ml, and median PSAD 0.53(0.30, 1.52)ng/ml 2 were recorded. According to the biopsy pathological results, all patients were divided into benign lesion group and prostate cancer group. PSA, PSAD, PV, and apparent diffusion coefficient (ADC) values were compared, and magnetic resonance imaging and clinical characteristics of patients with biopsy benign lesions were analyzed. Results:There were 11 cases (3.8%) with benign lesion and 278 cases (96.2%) with prostate cancer. The characters of 11 negative biopsy cases were displayed as follows: median age 69(66, 79)years, median body mass index 22.0(21.0, 25.5)kg/m 2, median PV 62.90(38.48, 71.96)ml, median PSA 5.55(2.99, 20.52)ng/ml, median PSAD 0.16(0.07, 0.24) ng/ml 2, median ADC 714.47(701.91, 801.26)×10 -6 mm 2/s, abnormal digital rectal and amination in 5 cases, smoking in 7 cases, and alcohol consumption in 4 cases. The median PV [62.90(38.48, 71.96) vs. 37.21(29.22, 47.82)ml, P<0.01], the PSA value [5.55(2.99, 20.52) vs. 23.53(11.14, 65.98)ng/ml, P<0.01], and the PSAD value [0.16(0.07, 0.24) vs. 0.58(0.31, 1.57)ng/ml 2, P<0.01] were significantly different between benign condition group and prostate carcinoma group. Benign condition group included 5 chronic prostatitis, 2 acute prostatitis (1 with focal adenocarcinoma), 2 granulomatous inflammation, and 2 tuberculous granulomatous inflammation. In 7 benign cases, PSA was less than 10 ng/ml, combined with frequent urination, urgency of urination and incontinence were founded. In 8 benign cases, the area of lesion was more than 50% of the total prostate area in the axial position and the imaging of magnetic resonance were diffused, with regular shape and uniform signal. The imaging of symmetrical distribution was in 6 cases. Conclusions:The benign condition with PI-RADS 5 lesions included chronic prostatitis, acute prostatitis, granulomatous inflammation and tuberculous granulomatous inflammation, among which prostatitis was the most common cause. The PSA value were less than 10 ng/ml in most benign cases, with symptoms such as frequent urination, urgency of urination and incontinence. The imaging of magnetic resonance were diffused, symmetrically distributed, with regular shape and uniform signal.
