To give full play to the important role of courses for ideological and political education in moral cultivation, teaching group in the course of oral histology and pathology in Zhejiang University systematically studied the teaching model of which ideological and political education integrated into the course of oral histology and pathology, and put forward a quality evaluation index system of the course. This paper emphatically introduces the general framework of the course, as well as the experience and practices in the aspects of resource mining, teaching design, curriculum evaluation, etc. The quality of the course was evaluated by using the system, which showed that the grade of the course was AAA (excellent) and 95.5% (275/288) students agreed to integrate ideological and political content into the course. The teaching group believes that the integration of the ideological and political content in the course reflects the complementary effect of "teaching" and "educating", and the ideological and political quality as well as the professional level of the teachers are the primary factor to determine the quality of the course. This paper aims at providing a reliable reference for promoting the construction of courses for ideological and political education in the area of oral medical education.

BACKGROUND@#It is not clear whether sacubitril/valsartan is beneficial for patients with heart failure (HF) with reduced ejection fraction (HFrEF) and low systolic blood pressure (SBP). This study aimed to investigate the efficacy and tolerability of sacubitril/valsartan in HFrEF patients with SBP < 100 mmHg.@*METHODS & RESULTS@#An observational study was conducted on 117 patients, 40.2% of whom had SBP < 100 mmHg without symptomatic hypotension, and 59.8% of whom had SBP ≥ 100 mmHg in an optimized HF follow-up management system. At the 6-month follow-up, 52.4% of patients with SBP < 100 mmHg and 70.0% of those with SBP ≥ 100 mmHg successfully reached the target dosages of sacubitril/valsartan. A reduction in the concentration of N-terminal pro-B-type natriuretic peptide was similar between patients with SBP < 100 mmHg and SBP ≥ 100 mmHg (1627.5 pg/mL and 1340.1 pg/mL, respectively; P = 0.75). The effect of sacubitril/valsartan on left ventricular ejection fraction was observed in both SBP categories, with a 10.8% increase in patients with SBP < 100 mmHg (P < 0.001) and a 14.0% increase in patients with SBP ≥ 100 mmHg (P < 0.001). The effects of sacubitril/valsartan on SBP were statistically significant and inverse across both SBP categories (P = 0.001), with an increase of 7.5 mmHg in patients with SBP < 100 mmHg and a decrease of 11.5 mmHg in patients with SBP ≥ 100 mmHg. No statistically significant differences were observed between the two groups in terms of the occurrence of symptomatic hypotension, deteriorating renal function, hyperkalemia, angioedema, or stroke.@*CONCLUSIONS@#Within an optimized HF follow-up management system, sacubitril/valsartan exhibited excellent tolerability and prompted left ventricular reverse remodeling in patients with HFrEF who presented asymptomatic hypotension.

Interleukin (IL)-36 is a family of cytokines that belongs to the larger IL-1 superfamily. IL-36 agonist/antagonist binds to the interleukin-36 receptor involving in physiological inflammation regulation and pathogenesis of many inflammatory diseases. In inflammatory joint diseases, the expression of IL-36 changes, and some studies have initially explored the role of IL-36 in these diseases. In psoriatic arthritis, IL-36 signal mediates plasma cell and fibroblast-like synoviocyte crosstalk presenting IL-36 agonist/antagonist imbalance. In rheumatoid arthritis, IL-36 agonists induce fibroblast-like synoviocyte to produce pro-inflammatory factors, while IL-36 antagonist deficiency leads to lesion progression. In osteoarthritis, IL-36 agonists induce chondrocytes to produce catabolic enzymes and pro-inflammatory factors. This article reviews the expression and function of IL-36 in different inflammatory joint diseases to provide a reference for revealing their pathogenic mechanisms and discovering therapeutic targets.

Objective:To explore the effect of oxidative stress on cognitive function following chest blast injury in mice.Methods:Sixty male C57BL/6 mice were divided into control group ( n=15) and chest blast group ( n=45) according to a random number table. The chest blast group was subgrouped at 1, 3, 7 days after injury for subsequent experiments. A self-developed blast injury device was used to prepare the mouse model of chest blast injury. Toklu score was used to evaluate the behavior changes in mice. Morris water maze test was used to evaluate the changes in spatial memory. HE staining was used to observe the pathological changes in the frontal cortex and hippocampus. Tissue reactive oxygen species (ROS) assay kit was used to detect ROS expression in the frontal cortex and hippocampus. Western blotting was used to assess changes of malondialdehyde (MDA) and cyclooxygenase-2 (COX2) in the frontal cortex and hippocampus. Results:The Toklu score of the chest blast group at 1 day after injury was (6.7±2.1)points, significantly higher than that of the control group [(2.0±0.0)points], as well as those of the chest blast group at 3 and 7 days after injury [(2.7±1.2)points and (2.0±0.0)points] (all P<0.01). There was no significant difference in the Toklu score between the control group and the chest blast group at 3 and 7 days after injury (all P>0.05). The Morris water maze test showed that the latency periods at 1 and 3 days after injury were 60.1(60.1, 60.1)seconds and 60.1(56.3, 60.1)seconds, significantly longer than that of the control group [10.1(3.9, 18.3)seconds] (all P<0.01). The latency period of the chest blast group at 7 days after injury was 60.1(30.5, 60.1)seconds, with no difference from the control group ( P>0.05). No significant differences were found in the latency periods of the chest blast group at 1, 3 and 7 days after injury (all P>0.05). In the control group, the pyramidal cells in the frontal cortex and hippocampus were regular in shape, with intensely-stained and clearly visible nuclei as well as uniform cytoplasm. In the chest blast group, diflerent degree of necrosis of pyramidal cells in the frontal cortex and strong cytoplasmic eosinophilia in the hippocampus were observed at different time points after injury. The levels of ROS in the frontal cortex of the chest blast group were (10.43±0.36)RFU/mg and (2.91±0.35)RFU/mg at 3 and 7 days after injury, which were significantly higher than that of the control group [(0.70±0.01)RFU/mg] ( P<0.05 or 0.01). The level of ROS in the frontal cortex of the chest blast group at 3 days after injury was significantly higher than that at 1 day [(2.13±0.65)RFU/mg] and that at 7 days after injury (all P<0.01). There were no statistical differences in the levels of ROS in the frontal cortex of the chest blast group at 1 and 7 days after injury ( P>0.05). The levels of ROS in the hippocampus of the chest blast group were (5.39±0.79)RFU/mg and (5.65±1.17)RFU/mg at 3 and 7 days after injury, which were significantly higher than those of the control group and of the chest blast group at 1 day after injury [ (0.73±0.06)RFU/mg and (2.33±0.02)RFU/mg] (all P<0.01). No significant differences were found between the levels of ROS in the hippocampus of the chest blast group at 3 and 7 days after injury and between the ROS levels of the control group and of the chest blast group at 1 day after injury (all P>0.05). The levels of ROS in the frontal cortex and hippocampus showed significant differences between the chest blast group at 3 and 7 days after injury (all P<0.01) but no significant differences between the control group and the chest blast group at 1 day after injury (all P>0.05). Western blotting showed that the levels of MDA in the frontal cortex of the chest blast group were 0.73±0.04, 0.83±0.04 and 0.99±0.06 at 1, 3 and 7 days after injury, which were significantly higher than that of the control group (0.56±0.04) ( P<0.05 or 0.01). The level of MDA in the frontal cortex of the chest blast group was significantly higher at 7 days after injury compared with that at 1 and 3 days after injury ( P<0.05 or 0.01), but there was no statistical difference between 1 day and 3 days after injury ( P>0.05). The levels of COX2 in the frontal cortex of the chest blast group were 2.93±0.02, 4.82±0.15 and 4.76±0.06 at 1, 3 and 7 days after injury, which were significantly higher than that of the control group (1.93±0.06) (all P<0.01). There were statistical differences in the levels of COX2 in the frontal cortex of the chest blast group at 3 and 7 days after injury compared with that at 1 day after injury (all P<0.01), but no statistical significance was found between 3 and 7 days after injury ( P>0.05). The levels of MDA in the hippocampus of the chest blast group were 0.92±0.11, 0.83±0.03 and 0.68±0.03 at 1, 3 and 7 days after injury, which were significantly higher than that of the control group (0.49±0.03) (all P<0.01). There was a significant difference in the level of MDA in the hippocampus of the chest blast group at 7 days after injury compared with those at 1 and 3 days after injury ( P<0.05 or 0.01), but the difference was not statistically significant among other groups (all P>0.05). The levels of COX2 in the hippocampus of the chest blast group were 0.88±0.06, 0.87±0.06 and 0.80±0.06 at 1, 3 and 7 days after injury, which were significantly higher than that of the control group (0.37±0.04) (all P<0.01). There were significant differences in the levels of COX2 of the chest blast group among 1, 3 and 7 days after injury (all P>0.05). Statistically significant differences were found between the levels of MDA in the frontal cortex and hippocampus of the chest blast group at 1 and 7 days after injury (all P<0.01), but no statistical significant difference between the control group and the chest blast group at 1 day after injury ( P>0.05). The levels of COX2 in the frontal cortex and hippocampus were significantly different among all groups (all P<0.01). Conclusions:In the short term after chest blast injury, there will be cognitive dysfunction in mice. Oxidative stress is one of the important contributing factors, and the cognitive damage in the frontal cortex is more serious than that in the hippocampus.

While the hippocampus has been implicated in supporting the association among time-separated events, the underlying cellular mechanisms have not been fully clarified. Here, we combined in vivo multi-channel recording and optogenetics to investigate the activity of hippocampal interneurons in freely-moving mice performing a trace eyeblink conditioning (tEBC) task. We found that the hippocampal interneurons exhibited conditioned stimulus (CS)-evoked sustained activity, which predicted the performance of conditioned eyeblink responses (CRs) in the early acquisition of the tEBC. Consistent with this, greater proportions of hippocampal pyramidal cells showed CS-evoked decreased activity in the early acquisition of the tEBC. Moreover, optogenetic suppression of the sustained activity in hippocampal interneurons severely impaired acquisition of the tEBC. In contrast, suppression of the sustained activity of hippocampal interneurons had no effect on the performance of well-learned CRs. Our findings highlight the role of hippocampal interneurons in the tEBC, and point to a potential cellular mechanism subserving associative learning.

Based on archival materials, the Xiangya's anti-epidemic history in a century from its establishment to 2020 is divided into 4 stages. The first stage (1906-1926), Edward Hicks Hume and YAN Fuqing, the founders of Xiangya, prevented and controlled smallpox and plague. The second stage (1929-1953), during the resumption of Xiangya, students prevented and controlled cholera, plague, dysentery, typhus, and other infectious diseases. In the third stage (1953-1999), in a peacetime, Xiangya actively fought against schistosomiasis, hydatidosis, malaria, leprosy, tuberculosis and other epidemics. The fourth stage (2000-2020), the era of Central South University. Medical staff in Xiangya fight SARS, influenza A (HN) flu, Ebola hemorrhagic fever, coronavirus disease 2019, etc. Over the past hundred years, Xiangya people joined together to spread benevolence and love, apply medical knowledge and skills, combat the epidemic and rescue people in difficulties, which made a great contribution to the motherland and the people.

Metabolomics methods were applied in the study of the toxicity of environmental pollutants. It has been shown that exposure to heavy metals such as mercury, arsenic, cadmium, chromium and lead could cause significant changes in energy, lipids, nucleic acids and amino acids in mammalian cells. After exposure to benzo(a)pyrene [B(a)P], the glands of Pinctada pumila could produce various changes, such as energy metabolic disorder, cell damage, signal transduction disorder, oxidative stress and osmotic disorder. Persistent organic compounds polychlorinated biphenyls (PCBs) could exert toxic effects on Zebrafish embryos through affecting amino acid metabolism, DNA and protein methylation and biosynthesis. After exposure to endocrine disruptors, such as nonylphenol, octylenediester phthalate and bisphenol propane, goldfish showed energy, lipid and nucleic acid metabolic disorders.

Cytochrome P450(CYP450),one of the most important enzymes in the human body,medi?ates the activation and toxicity of indirect poisons as well as indirect carcinogens. CYP450 is a super?family mainly composed of CYP1A, CYP1B, CYP2A, CYP2B, CYP2C, CYP2E, CYP2W, CYP3A and their activities are widely modulated by epigenetic manners, such as DNA methylation, histone modifi?cation and microRNA interference.Indirect carcinogens including benzo(a)pyrene,2,3,7,8-tetrachlorod?ibenzo-p-dioxin,diethylstilbestrol,aflatoxin B1 and cyclophosphamide,can change epigenetic modifica?tions, such as specific changes in DNA methylation, histone acetylation, methylation or ubiquitination, and up-or down-regulation of microRNA expression,which affect the function of the major subtypes of CYP450 and their role in indirect carcinogen activation.

Objective To investigate the relationships between expressions of HPV and EBV in larynge-al carcinoma. Methods DNA flow-through hybridization and gene chip genotyping technology(HybriMax)and real-time quantitative PCR were used for 37 subtypes of HPV detection and quantitative detection of EBV in 101 cases of laryngeal cancer paraffin embedded tissue specimens. 43 cases of vocal cord polyp of paraffin embedded tissue specimens were used as the controls. Results The positive rate of laryngeal carcinoma was 13.86% in group HPV and 9.3% in the control group ,with no statistically significant difference between the positive expres-sions of HPV in the laryngeal carcinoma group and control group(P>0.05). The positive rate of laryngeal carci-noma was 63.37% and 13.95%,respectively ,in group EBV ,and the control group ,with significant difference between them(P 0.05),but the difference was statistically significant in highly differentiated EBV as compared with those with low differentiation type,medium differentiation and poor differentiation(P 0.05). Conclusions The incidence of laryngeal carcinoma is closely related with EBV infection ,possibly relationed with HPV and high-risk subtypes of HPV have a certain role in the process of induced laryngeal carcino-ma. The gender ,age and duration of disease have no significant correlation with EBV infection. This study will provide a basis for further invesgitation of pathogenesis of laryngeal cancer and prevention and treatment of larynge-al cancer.

5-Lipoxygenase, one of lipoxygenase isozymes, is a well-studied oxidative metabolism enzyme. It widely exists in various human tissues and cells, participates in the oxidative metabolism of endogenous and exogenous chemicals, and produces a variety of metabolites, all of which contribute to the occurrence of human diseases, such as inflammation, asthma, atherosclerosis, and tumor and so on. The expression of 5-lipoxygenase is at low level in normal human tissues while at high level in abnormal tissues. 5-Lipoxygenase is closely related to many kinds of diseases in human ovary, brain, cardiovascular system, lung, liver, pancreas and other tissues. The abnormal expression of 5-lipoxygenase tends to promote the development of the disease.

Histopathological changes in the left testis of the rats were observed by HE staining and the levels of the reproductive hormones T, FSH, and LH in the serum were determined by ELISA.</p><p><b>RESULTS</b>Compared with group B, group A showed clear structure of seminiferous tubules, orderly arrangement of spermatogenic cells, a slightly decreased number of sperm in some seminiferous tubular lumens, and shed spermatogenic cells in the rat testis tissue; group C exhibited thinner seminiferous epithelia, disordered structure of seminiferous tubules, irregular arrangement of spermatogenic cells, decreased number of mature sperm and obvious shedding of spermatogenic cells in seminiferous tubular lumens; group D manifested similar findings to those of group C, with even more shed spermatogenic cells that blocked the tubular lumens. The levels of serum T, LH, and FSH were (0.490 +/- 0.028) ng/ml, (6.290 +/- 0.515) ng/L, and (1.837 +/- 0.127) IU/L in group A, (0.460 +/- 0.024) ng/ml, (5.881 +/- 0.124) ng/L, and (1.707 +/- 0.098) IU/L in group B, (0.417 +/- 0.021) ng/ml, (5.123 +/- 0.271) ng/L, and (1.620 +/- 0.115) IU/L in group C, and (0.378 +/- 0.021) ng/ml, (4.504 +/- 0.279) ng/L and (1.562 +/- 0.216) IU/L in group D, all decreased in group B as compared with A (P > 0.05). The decreases of T and LH were extremely significant (P < 0.01) and that of FSH was significant in groups C and D (P < 0.05) in comparison with A.</p><p><b>CONCLUSION</b>LPS-induced inflammation affects the testicular tissue and reproductive endocrine function of male rats, resulting in decreased levels of serum T, LH, and FSH.</p>

Objective To investigate and evaluate the iodine nutritional status of school-age children in Yi county of Heibei Province,and to provide scientific basis for the development of control measures to iodine deficiency disorders.Methods Retrospectinely analyzed school-age children urinary iodine monitoring results of Yi County of Hebei Province from 1998 to 2011.One township was selected randomly in each of the five directions (east,west,south,north and center) from 1998 to 2011.One elementary school was randomly chosen in each of the five townships.And at least 20 urine samples of 8-10 years old children were randomly collected in each school selected.Urinary iodine contents were determined through arsenic cerium catalytic spectrophotometric method.Urinary iodine determination standard according to The Standard of Iodine Deficiency Disorders Elinination (GB 16006-2008) and The Iodine Deficiency Disorders Elinination Guide.Results A total of 1725 children urinary samples were collected from 1998 to 2011,urinary median was 243.26 μg/L,each of the median urinary iodine was higher than 100 μg/L.The ratio of urinary iodine less than 100 μg/L was < 50% over the years,and less than 50 μg/L was < 20%.Overall,the highest value of urinary iodine stayed at approximately 200 μg/L,showing positively skewed distribution that was skewed to the right.Urinary iodine level was compared among different ages,gender and ethnicity,and the difference was not statistically significant(P > 0.05).Conclusions In recent years,the iodine intake of school-age children of Yi County can meet the body needs,and the iodine nutrition is at an appropriate level.
