Objective: To evaluate the knowledge, attitude and behavior on blood lipid among people in Changsha and to provide evidences for prevention and control of blood lipid abnormality. Methods: A total of 400 cases were randomly selected on the questionnaire of the knowledge, attitude and behavior on blood lipid in ordinary adults who participate in health examination in Xiangya Hospital. Blood lipid related physical examination was conducted at the same time. hTe health examination participants were divided into several groups according to their sex, age, degree of education, marriage and family income. The influential factors for knowledge, attitude and behavior were analyzed. Results: hTe knowledge score of blood lipid for health examination participants was 18.33±8.67 (total score 37), the attitude score was 6.63±2.45 (total score 9) and the behavior score was 8.32±2.65 (total score 16). hTe scores of female was higher than that of male in the terms of knowledge and behavior (bothP<0.05); the scores in the 40–49 age group were lower than those in the other age groups (all P<0.05); the scores in the junior high school group were lower than those in the other education groups (allP<0.05); the scores in the family group with less than 2 000 yuan income were lower than those in other family groups with different income (allP<0.05). The multiple stepwise regression analysis showed that: 1) the knowledge on blood lipid score was inlfuenced by ages and education background (bothP<0.05); 2) while the attitude of blood lipid was inlfuenced by four factors such as education background, systemic blood pressure, blood sugar and triglyceride(allP<0.05); 3) the behavior on blood lipid was inlfuenced by ifve factors such education background, triglyceride, systemic blood pressure, blood sugar and ages (allP<0.05). Conclusion: The knowledge, attitude and behavior on blood lipid among health examination participants were mostly influenced by education background, gender and ages. Thus, clinical medical staff should prevent the blood lipid abnormality through the health education and improve the knowledge in normal people. hTe group of 40–49 age male should be thought as the primary intervention subjects. hTe knowledge, attitude and behavior on blood lipid among the general population is also related to individual’s blood pressure, blood sugar and triglyceride. So the clinical medical staff should also improve the knowledge of blood lipid, blood pressure and blood sugar in general population for improving their attitude and unhealthy habits. In addition, the active control of blood sugar and blood pressure can enhance the overall health status of the general population.

Cysteine dioxygenase 1 (CDO1) gene is a non-heme structured, iron-containing metalloenzyme involved in the conversion of cysteine to cysteine sulfinic acid to regulate cysteine accumulation in vivo. Elevated levels of cysteine have been shown to be cytotoxic and neurotoxic, and this is the first important step in the breakdown of cysteine metabolism in mammalian tissues. The human CDO1 gene is located on chromosome 5q23.2. Studies have shown that deletion or epigenetic silencing of this chromosomal region contributes to tumorigenesis. It is highly expressed in the liver and placenta, and weakly in the heart, brain and pancreas. CDO1 is a tumor suppressor gene (TSG) with a wide range of functions, which can be involved in various biological processes such as tumor cell proliferation, differentiation, apoptosis and iron death, thus affecting the tumor development. CDO1 is epigenetically regulated in human cancers, compared to normal tissues. The CDO1’s mRNA or protein expression levels were significantly down-regulated in tumor tissues, whereas promoter DNA methylation of the CDO1 gene usually accumulates with the progression of human cancers. Aberrant hypermethylation on the CDO1 promoter is a common event in tumor cells, which leads to transcriptional inactivation and silencing of the CDO1 gene. High frequency of methylation of CDO1 gene promoter methylation region in a variety of tumors including breast, oesophageal, lung, bladder, gastric and colorectal cancers. CDO1 gene promoter methylation levels reflect cancer progression and malignant tumorigenesis, which is a common molecular indicator explaining poor prognosis in human cancers. Treatment with 5-aza-2′-deoxycytidine (a drug that promotes demethylation) reactivated the CDO1 expression in most cancer cell lines, indicating that the transcriptional expression of CDO1 is closely correlated with its promoter methylation level, CDO1 gene promoter methylation and tumor progression have also received increasing attention from researchers. It was found that CDO1 gene promoter hypermethylation can be used as an early tumor marker for clinical aid diagnosis and helps to differentiate cancerous from benign diseases. It was also found that CDO1 promoter DNA methylation showed reliable tumor monitoring potential in human body fluids, and furthermore, the degree of CDO1 promoter methylation was strongly correlated with resistance to chemotherapy with tumor drugs, which would be helpful in evaluating the efficacy of chemotherapeutic drugs. Thus, CDO1, a common promoter methylation gene in human cancers, is closely associated with the development of a wide range of tumors and is one of the most promising candidate genes for assessing tumor-specific epigenetic changes. This article reviews the biological functions of CDO1 and its promoter DNA methylation in tumors, focusing on the mechanism of CDO1 DNA promoter methylation in tumors, with a view to providing theoretical guidance for the clinical diagnosis and treatment of tumors with CDO1 as a potential therapeutic target.

PURPOSE: Lung adenocarcinoma (LA) is one of the major types of lung cancer. MicroRNAs (miRNAs) play an essential role in regulating responses of natural killer (NK) cells to cancer malignancy. However, the mechanism of miR-218-5p involved in the killing effect of NK cells to LA cells remains poorly understood. MATERIALS AND METHODS: The expression of miR-218-5p was examined by quantitative real-time polymerase chain reaction (qRT-PCR). Serine hydroxymethyl transferase 1 (SHMT1) level was detected by qRT-PCR or western blots. Cytokines production of interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were detected by ELISA. The killing effect of NK cells to LA cells was investigated using lactate dehydrogenase cytotoxicity assay kit. The interaction of miR-218-5p and SHMT1 was probed by luciferase activity assay. Xenograft model was established to investigate the killing effect of NK cells in vivo. RESULTS: miR-218-5p was enhanced and SHMT1 was inhibited in NK cells of LA patients, whereas stimulation of interleukin-2 (IL-2) reversed their abundances. Addition of miR-218-5p reduced IL-2-induced cytokines expression and cytotoxicity in NK-92 against LA cells. Moreover, SHMT1 was negatively regulated by miR-218-5p and attenuated miR-218-5p-mediated effect on cytotoxicity, IFN-γ and TNF-α secretion in IL-2-activated NK cells. In addition, miR-218-5p exhaustion inhibited tumor growth by promoting killing effect of NK cells. CONCLUSION: miR-218-5p suppresses the killing effect of NK cells to LA cells by targeting SHMT1, providing a potential target for LA treatment by ameliorating NK cells function.

OBJECTIVE: To explore the knowledge of, attitude to and practice in nutrition and food safety, the influence factors, and to provide reference for relevant health education programs. METHODS: A total of 510 randomly selected students from Grade 1 to 3 randomly selected were surveyed by a nutrition and food safety questionnaire in Huize of Yunnan Province and Zhen'an of Shaanxi Province. Multiple-linear regression was used to analyze the influence factors of nutrition and food safety. RESULTS: The correct answer rate on nutrition and food safety knowledge of the pupils from Grade 1 to 3 was 74.4%. Nutrition and food safety knowledge score was 11.16±2.51, but only 7.8% of the students correctly answered "How much water should we drink every day". Students who agreed that it is necessary to learn nutrition and food safety knowledge in school accounted for 78.6% and 73.9%, respectively. At least half of the students showed correct behaviors in 7 aspects. The students who ate beans and meat daily or regularly accounted for 28.4% and 34.9%, but only 9.2% of the students drank more than 7 cups of water daily. The multiple-linear regression showed that the major influence factors were the area, grade, status of lodge and singleton. CONCLUSION Education is needed for students to form better dietary habits, especially those in low grades, non-singleton, and in board schools.

OBJECTIVES: Central serous chorioretinopathy (CSC) is generally a common fundus disease in young and middle-aged Asian men. Acute and chronic CSC can lead to different degrees of injury to the retinal blood flow. This study aims to observe and compare the blood flow density in different retinal capillary layers in patients with acute and chronic CSC using optical coherence tomography angiography (OCTA) technology. METHODS: Twelve patients with acute CSC and 8 patients with chronic CSC including 12 eyes with acute CSC (acute CSC eye group), 11 eyes with chronic CSC (chronic CSC eye group), and 17 normal eyes (normal eye group) were enrolled in this study. All patients underwent 3 mm×3 mm, 6 mm×6 mm macular OCTA scanning. The retinal microvascu-lature was divided into superficial vascular complexes (SVC), intermediate capillary plexuses (ICP), and deep capillary plexuses (DCP) using the projection resolved-OCTA algorithm. Inner retina includes SVC, ICP, and DCP. The vessel density in each retinal layer and the inner retina were calculated and compared. RESULTS: Macular OCTA scanning of 3 mm×3 mm showed that there was no significant difference in blood flow density of SVC and ICP among the 3 groups (both P>0.05); blood flow density of DCP and inner retina in the chronic CSC eye group was significantly lower than that in the acute CSC eye group and the normal eye group (all P<0.05); there was no significant difference in retinal blood flow density of different layer between the acute CSC eye group and the normal eye group (all P>0.05). Macular OCTA scanning of 6 mm×6 mm showed that inner retinal blood flow density of the chronic CSC eye group was significantly lower than that of the acute CSC eye group and the normal eye group (both P<0.05); there was no significant difference in blood flow density of SVC among the 3 groups (P>0.05). CONCLUSIONS The vessel density of DCP and inner retina in the eyes with chronic CSC are significantly reduced, which may result in impaired visual function. Therefore, we recommend that patients with acute CSC should be properly treated to avoid progressing into chronic CSC.

INTRODUCTION: The purpose of this study was to assess the application of the early warning score system (EWS-S) and gauge physician awareness, perceptions of necessity and attitudes regarding these tools based on previously experienced unnoticed clinical deterioration (CDET). METHODS: A cross-sectional survey was carried out via an online questionnaire at a large 3,500-bed Class 3A general hospital in China. A total of 299 physicians of adult general wards were asked to answer a translated questionnaire that was localised from the original version. Demographic profiles of patients were included as well as three other sections assessing awareness of CDET/EWS-S and gauging attitudes towards and perceptions of the necessity of EWS-S at our hospital. RESULTS: A high level of physician awareness of the CDET problem was observed. Most physicians knew about the existence of a systematic assessment tool for clinical application. Physicians with previous experience in reanimation, unplanned transfer to intensive care unit (UTICU) and/or death tended to consider EWS-S necessary in attentive and well-trained staff (p < 0.05). Physicians who had previous experience with UTICU were more likely to recommend implementing EWS-S in their wards compared with those without such experience (p < 0.05). CONCLUSION Most physicians have positive attitudes towards EWS-S. However, their awareness should be further heightened. Physicians who had previous experience with CDET/UTICU were more likely to employ EWS-S in their clinical practices. To better facilitate the implementation of EWS-S in Chinese hospitals, existing facilities, policy supports, standardised managements and the development of information systems should be strengthened.

To investigate the effects of saponins extracted from Panax japonicus(SPJ) on cardiomyocyte apoptosis in natural aging rats and explore its underlying mechanisms. SD male rats were randomly divided into four groups: young control group, natural aging group, SPJ low dose group and SPJ high dose group, with 10 rats in each group. The rats in natural aging group, SPJ low and high dose groups were respectively treated with normal saline, SPJ 10 and 60 mg•kg-1•d-1 from the beginning of 18 month-old, 6 days per week for 6 months till 24 month-old. Then the animals were sacrificed. Their myocardial morphology changes were observed by using haematoxylin-eoin(HE) staining; cardiomyocyte apoptosis was tested by using Tunel assays; and the protein expression levels of Bcl-2, Bax, IL-1β, TNF-α, AMPK, p-AMPK, Sirt1, and Ac-NF-κB p65 in myocardial tissues of rats were detected by Western blot. The results showed that SPJ could effectively improve the arrangement disorder of myocardial fibers, reduce the infiltration of inflammatory cells and inhibit cardiomyocyte apoptosis in natural aging rats. At the same time, SPJ could significantly inhibit the protein expression of Bax, IL-1β, TNF-α and Ac-NF-κB p65, and increase the expression of Bcl-2, Bcl-2/Bax, p-AMPK/AMPK and Sirt1 in the heart tissues of natural aging rats. SPJ can effectively inhibit cardiomyocyte apoptosis in natural aging rats, and its mechanisms may be related with the regulation of inflammatory reaction by AMPK/Sirt1/NF-κB signaling pathway.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
