Application of Ancient Books in Clinical Practice Guidelines and Expert Consensus of Traditional Chinese Medicine： Current Status and Methodological Recommendations / 中医杂志

ObjectiveTo explore the current status and issues regarding the application of ancient books in clinical practice guidelines and expert consensus of traditional Chinese medicine （TCM） published in China， and to provide methodological recommendations for the incorporation of ancient books in the development of TCM guidelines. MethodsWe searched China National Knowledge Infrastructure （CNKI）， WanFang Data， VIP， SinoMed， PubMed， Embase， as well as six industry websites including China Association of Chinese Medicine， National Group Standards Information Platform， and Chinese Association of the Integration of Traditional and Western Medicine，etc. TCM clinical practice guidelines or expert consensus issued during January 1st， 2017， to November 26th， 2022 were searched. Clinical practice guidelines or expert consensus that explicitly referred to ancient books were included， and the content regarding the searching for ancient books， sources of access to ancient books， methods of evaluating the level of evidence， methods of evaluating the level of recommendation， and methods of evaluating the evidence for the ancient books were analysed. ResultsA total of 1,215 TCM clinical practice guidelines or expert consensus were retrieved， with 442 articles explicitly mentioning the application of ancient books， including 300 （67.87%） clinical practice guidelines and 142 （32.13%） expert consensus. Sixty of the 442 publications explicitly reported that ancient books searching had been conducted （13.57%）； among these 60 publications 27 （45.00%） explicitly reported ancient books searching strategies， and the most frequent method was manual searching with a total of 24 articles （40.00%）. The most popular search source was Chinese Medical Dictionary， a TCM classics database， with a total of 18 articles. 197 articles （44.57%） explicitly reported the evaluation criteria for the level of evidence， of which 141 articles （71.57%） involved the evaluation criteria for the ancient books； 413 articles （93.44%） mentioned ancient books in the recommendations， and only the source of formula name was mentioned in 409 （99.03%） of the publications. ConclusionThe current application of ancient books in TCM clinical practice guidelines and expert consensus is limited， with issues of non-standard searching and evaluation methods. Standar-dization and uniformity are needed in evidence grading and recommendation standards. Future research should clarify the scope and methods of applying ancient book， emphasize their integration with modern research evidence， and enhance their value and quality in the development of TCM clinical practice guidelines.

Thinking on ideological and political education in Medical Parasitology teaching / 中国血吸虫病防治杂志

With the deepening reform of ideological and political education, Medical Parasitology teaching needs to update the teaching concept, change the teaching ideas, as well as keep trying to combine ideological and political education with the curriculum content closely. In addition to teaching students’ basic knowledge and practical skills, teachers are needed to cultivate their moral literacy and political awareness through course teaching, so as to provide the basis for students’ subsequent adaptations to social environments and jobs. Currently, the study of ideological and political education in Medical Parasitology teaching is still in the exploratory stage. Therefore, colleges and universities need to carry out effective construction of ideological and political education in Medical Parasitology teaching, in order to achieve good teaching outcomes and provide insights into ideological and political education in teaching.

Research progress on biological mechanism of interferon-inducible protein 16 / 中国药理学通报

Interferon γ-inducible protein 16(IFI16)is one member of human pyrin and HIN domain-containing protein(PYHIN)family(also known as interferon-inducible p200 pro-tein family),which is widely present in human organs and tis-sues,and is involved in cell cycle regulation,senescence and ap-optosis,even in immune reaction.The content and localization of IFI16 may change under different physiological and pathological conditions,and recent studies have revealed that it may play an important role in the development of antiviral,tumor,inflammato-ry diseases and other diseases.In this paper,we review its mechanism and the current status of its research in diseases,with the aim of providing a reference for the in-depth study of IFI16.

Analysis of dyslipidemia management status in atrial fibrillation patients with very high and high risk of atherosclerotic cardiovascular disease / 中华心血管病杂志

Objective: To analyze the status of statins use and low-density lipoprotein cholesterol (LDL-C) management in patients with atrial fibrillation (AF) and very high/high risk of atherosclerotic cardiovascular disease (ASCVD) from Chinese Atrial Fibrillation Registry (CAFR). Methods: A total of 9 119 patients with AF were recruited in CAFR between January 1, 2015 to December 31, 2018, patients at very high and high risk of ASCVD were included in this study. Demographics, medical history, cardiovascular risk factors, and laboratory test results were collected. In patients with very high-risk, a threshold of 1.8 mmol/L was used as LDL-C management target and in patients with high risk, a threshold of 2.6 mmol/L was used as LDL-C management target. Statins use and LDL-C compliance rate were analyzed, multiple regression analysis was performed to explore the influencing factors of statins use. Results: 3 833 patients were selected (1 912 (21.0%) in very high risk of ASCVD group and 1 921 (21.1%) in high risk of ASCVD group). The proportion of patients with very high and high risk of ASCVD taking statins was 60.2% (1 151/1 912) and 38.6% (741/1 921), respectively. Attainment rate of LDL-C management target in patients with very high and high risk were 26.7% (511/1 912) and 36.4% (700/1 921), respectively. Conclusion: The proportion of statins use and attainment rate of LDL-C management target are low in AF patients with very high and high risk of ASCVD in this cohort. The comprehensive management in AF patients should be further strengthened, especially the primary prevention of cardiovascular disease in AF patients with very high and high risk of ASCVD.

Coronary Heart Disease and Obstructive Sleep Apnea Syndrome： Interpretation and Reflection Based on Simultaneous Treatment of Heart and Lung in Traditional Chinese Medicine / 中国实验方剂学杂志

As the overweight and obese population is growing， the incidence of obstructive sleep apnea is rising， and most of the cases are complicated with coronary heart disease and other cardiovascular diseases. The two diseases affect each other and seriously endanger the patients' health， becoming a major public health problem of global concern. It is of great clinical importance to explore the combination of Chinese and Western medicine in the prevention and treatment of coronary heart disease complicated with obstructive sleep apnea syndrome. Researchers have explored the relationship between the two based on traditional Chinese medicine（TCM） theory and found that the two diseases belong to the TCM disease categories of chest impediment and snoring， respectively， and their co-morbidity is associated with the abnormal physiological functions of the heart and lungs. The failure of the heart to govern blood leads to the generation of blood stasis， and that of the lung to govern Qi movement leads to the generation of phlegm. The accumulation of phlegm and blood stasis in the chest causes chest impediment and snoring due to obstruction of the airway. This paper discusses the internal linkage between the pathogenesis of coronary heart disease and obstructive sleep apnea syndrome in Chinese and Western medicine from the TCM theory of heart-lung correlation. Furthermore， this paper proposes the treatment principles of simultaneously treating the heart and lung and activating blood and resolving phlegm， aiming to provide a theoretical basis for the clinical prevention and treatment of coronary heart disease complicated with obstructive sleep apnea.

Determination of biological exposure limit of damage in red blood cells caused by exposure to polycyclic aromatic hydrocarbons using benchmark dose method in general population / 公共卫生与预防医学

Objective To explore the biological exposure limit of blood system damage caused by long-term exposure to polycyclic aromatic hydrocarbons (PAHs) in non-occupational population by using the benchmark dose method, and to provide relevant reference for further improving the assessment of PAHs-induced health damage effects. Methods Adult residents living in downwind direction of a coke-oven plant in Shanxi Province were selected as the research subjects, and the information collected from baseline was used as the control. The metabolites of PAHs in urine were used as exposure biomarker, and the abnormal rate of red blood cell index was used as response biomarker. The relationship between urinary OH-PAHs and the erythrocyte damage rate was analyzed, and the benchmark dose (BMD) and the lower confidence limitation for the benchmark dose (BMDL) were calculated using Bayesian dose-optimizing software. Results The urinary PAH metabolites were mainly naphthalene and fluorene. The detection concentrations of 2-OHFlu and 1-OHPhe in the final year were higher than those in the baseline (P<0.05). With the increase of exposure years, the abnormal rate of red blood cells in the final year was higher than that in the baseline (P<0.05). In addition, the abnormal rate of red blood cells increased with the increase of the concentrations of five metabolites of PAHs in urine, and the chi-square trend test was significant (P<0.05). The benchmark dose (BMD) of OH-PAHs was 0.67 μmol/mol Cr, 0.82 μmol/mol Cr, 1.40 μmol/mol Cr and 0.78 μmol/mol Cr, respectively. The BMD of 2-OHNap in people with barbecue diet habits was 0.23 μmol/mol Cr. The BMD of 2-OHNap in people without barbecue diet habits was 1.44 μmol/mol Cr. Conclusion There is a dose-response relationship between the concentration of PAHs metabolites in urine and the damage of red blood cells. Long-term exposure to PAHs can lead to hematological damage. It is suggested that targeted public health interventions should be formulated to reduce the exposure of the general population to PAHs.

Effect of sugammadex on postoperative nausea and vomiting after surgery for intracranial aneurysm / 中华外科杂志

Objective: To investigate the effect of sugammadex on postoperative nausea and vomiting(PONV) after intracranial aneurysm surgery. Methods: Data from intracranial aneurysms patients who met the inclusion and exclusion criteria and underwent interventional surgery in the Department of Neurosurgery, Peking University International Hospital from January 2020 to March 2021 were prospectively included. According to the random number table method, the patients were divided by 1∶1 into the neostigmine+atropine group (group N) and the sugammadex group (group S). Use an acceleration muscle relaxation monitor for muscle relaxation monitoring, and administer neostigmine+atropine and sugammadex to block residual muscle relaxation drugs after surgery. The incidence rates of PONV and severity, the appearance of anesthesia, and the correlation between PONV and postoperative complications were recorded in both groups during five periods after surgery: 0-0.5 hours (T1),>0.5-2.0 hours(T2),>2.0-6.0 hours (T3),>6.0-12.0 hours (T4) and >12.0-24.0 hours (T5). Group comparisons of quantitative data were performed by the independent sample t-test, and categorical data was performed by the χ2 or rank sum test. Results: A total of 66 patients were included in the study, including 37 males and 29 female, aged (59.3±15.4) years (range: 18 to 77 years). The incidence rates of PONV of 33 patients in group S at different time periods of T1, T2, T3, T4, and T5 after surgery were respectively 27.3%(9/33),30.3%(10/33),12.1%(4/33),3.0%(1/33),0(0/33),and the incidence rates of PONV of 33 patients in the group N at different time periods of T1, T2, T3, T4 and T5 after surgery were respectively 36.4%(12/33),36.4%(12/33),33.3%(11/33),6.1%(2/33) and 0(0/33).The incidence of PONV was lower in the group S only in the T3 period after reversal than in the group N (χ2=4.227, P=0.040).However, there was no statistically significant difference in the incidence of PONV between the two groups of patients in other periods (all P>0.05). The recovery time for spontaneous breathing in patients in group S was (7.7±1.4) minutes, the extubation time was (12.4±5.3) minutes, and the safe exit time for anesthesia recovery was (12.3±3.4) minutes; the N groups were (13.9±2.0) minutes, (18.2±6.0) minutes, and (18.6±5.2) minutes, respectively; three time periods in group S were shorter than those in group N, and the differences were statistically significant (all P<0.05). The results regarding the occurrence of complications in patients with different levels of PONV at different time intervals after surgery in the two groups were as follows: in the T3 time period of group N, a significant difference was observed only in the occurrence of postoperative complications among patients with different levels of PONV (χ2=24.786, P<0.01). However, in the T4 time period, significant differences were found in the occurrence of postoperative complications among both the same level and different level PONV patients (χ2=15.435, 15.435, both P<0.01). Significant differences were also observed in the occurrence of postoperative complications among the same level and different level PONV patients in both the T3 and T4 time periods of group S (all P<0.01). Conclusion: Sugammadex can be used to reverse muscle relaxation in patients undergoing intracranial aneurysm intervention surgery,and it does not have a significant impact on the incidence of PONV, it can also optimize the quality of anesthesia recovery and reduce the incidence of complications after intracranial aneurysm embolization surgery.

Study on Quality Evaluation of Honeysuckle Oral Liquid Based on Quality Markers of Anti-Inflammatory Effect / 世界科学技术-中医药现代化

Objective To establish a quality traceability evaluation method for the whole honeysuckle oral solution process by identifying and screening its anti-inflammatory quality markers.Methods UPLC/-TOF-MS was used to analyze the iridoids and phenolic acids in oral solution,and the correlations were constructed by molecular network technology.The HPLC fingerprints of multiple batches of oral solution were established,and similarity analyses were performed to identify key pharmacodynamic molecules.The key anti-inflammatory quality markers were confirmed by the NF-κB dual luciferase assay system.Further,the quantification of 12 quality markers of iridoids and phenolic acids in oral solution was established separately based on the dual-wavelength HPLC technique.The quality of the oral solution was evaluated by examining the extraction and transfer rate of quality markers during the processing of raw materials and preparations and thermal stability.Results A total of 9 iridoids and 6 phenolic acids were identified in the oral solution,and the possible conversion relationships between their components were depicted.Fingerprint analysis of 11 batches of oral liquids showed that the composition of their main peaks was the same,with a similarity of more than 90%.Among them,6 iridoids(loganic acid,secologanoside,secologanic acid,sweroside,secoxyloganin,secologanin)and 6 phenolic acids(neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,isochlorogenic B,isochlorogenic A,isochlorogenic C)exhibited NF-κB inhibitory activity,which were the main pharmacological components and could be used as quality markers.The traceability of the above 12 quality markers was investigated in a multi-batch process based on the dual-wavelength HPLC method.The thermal stability studies of the raw materials revealed that the contents of their total iridoids and phenolic acids remained stable.Still,some of them would be transformed between components.The production process of the oral solution was stable,and the transfer rates of the iridoids and phenolic acids during the extraction,concentration and preparation were over 76%and 63%,respectively.Conclusion The method is stable,reliable,easy to operate and can evaluate the full honeysuckle oral solution process,which provides an effective means for the quality control of honeysuckle herbs and preparations.

Changes in topological properties of brain functional network after induction of general anesthesia in patients with glioma / 中华麻醉学杂志

Objective:To evaluate the changes in topological properties of brain functional network after induction of general anesthesia in the patients with glioma.Methods:Twenty-two patients scheduled for elective intracranial glioma resection were selected.Resting-state functional magnetic resonance imaging was performed during wakefulness and general anesthesia with endotracheal intubation in patients with glioma. Large-scale functional brain networks of each patient were constructed based on 123 regions of interest in non-surgical hemisphere. Global properties (local efficiency, clustering parameter, shortest path length, global efficiency, small world) and nodal properties (nodal degree, nodal efficiency, and between centrality) in brain functional networks were then compared between wakefulness and general anesthesia.Results:Eighteen patients were finally enrolled. Compared with the status during wakefulness, the local efficiency and clustering parameter on non-surgical side significantly decreased ( P<0.05), no significant change was found in the shortest path length and global efficiency ( P>0.05), and small world was greater than 1 throughout the entire density range; the nodal degree, nodal efficiency and between centrality of nodes located in the medial/mesal regions, such as the medial prefrontal cortex, posterior cingulate gyrus/precuneus, medial temporal lobe, anterior cingulate gyrus, thalamus, amygdala, were significantly reduced ( P<0.05); however, these node parameters increased significantly in the lateral brain regions ( P<0.05) except for the primary auditory and somatosensory cortex, which also decreased significantly after induction of general anesthesia( P<0.05). Conclusions:The functional segregation of brain functional network is widely inhibited after induction of general anesthesia, but the functional integration is still retained. The lateral brain regions show no anticorrelation with the medial brain region during general anesthesia.

Objective:To study the value of myocardial perfusion imaging (MPI) and coronary flow reserve (CFR) combined with coronary artery calcium score (CACS) in the diagnosis of obstructive coronary artery disease (CAD).Methods:From January 2019 to December 2020, 96 confirmed or suspective CAD patients (65 males, 31 females; age: 30-81 years) who completed rest/stress MPI, CFR and CACS defection in Fuwai Central China Cardiovascular Hospital were retrospectively analyzed. Coronary angiography (CAG) was used as the diagnostic standard to calculate the sensitivity and accuracy of MPI, CFR and MPI/CFR combined with CACS in the diagnosis of CAD. The χ2 test was used to compare the diagnostic efficiency of different methods. Results:The diagnostic sensitivity of MPI was 76.06%(54/71), and the accuracy was 75.00%(72/96), while the sensitivity increased to 97.18%(69/71; χ2=13.67, P<0.001) and the accuracy increased to 87.50%(84/96; χ2=4.92, P=0.020) with significant differences after combined with CACS. The sensitivity and accuracy of CFR were 91.55%(65/71)and 87.50%(84/96), which increased to 97.18%(69/71; χ2=2.12, P=0.137) and 89.58%(86/96; χ2=0.21, P=0.411) with no significant differences after combined with CACS. The sensitivity of MPI in the diagnosis of three-vessel CAD was 70.00%(21/30), which increased to 100%(30/30; χ2=7.75, P=0.004) after combined with CACS; while the sensitivity of MPI combined with CACS in the diagnosis of single-vessel and double-vessel CAD were not significantly improved ( χ2 values: 3.29, 1.51, P values: 0.114, 0.416). Conclusion:The combination of MPI and CACS can significantly improve the diagnostic efficiency of CAD, contributed by the improvement of the diagnostic sensitivity in three-vessel disease; whereas the diagnostic efficiency of CFR for CAD is not significantly improved after combined with CACS.

Effect of different lithotomy positions on hemodynamics in patients undergoing laparoscopic total hysterectomy / 中国基层医药

Objective:To analyze the effect of different lithotomy positions on hemodynamics in patients undergoing laparoscopic total hysterectomy.Methods:A total of 50 patients who underwent laparoscopic total hysterectomy at Zhoushan Women and Children's Hospital between January 2020 and June 2021 were included in this study. The patients were randomly divided into a control group and an observation group using a random number table method, with 25 patients in each group. The control group underwent conventional lithotomy position total laparoscopic hysterectomy, while the observation group underwent high and low lithotomy position total laparoscopic hysterectomy. The general surgical indicators, respiratory function indicators, blood gas analysis indicators, hemodynamic levels, incidence of complications, and clinical efficacy were compared between the two groups.Results:The general surgical indicators and airway peak pressure indicators in the observation group were significantly lower than those in the control group (both P < 0.05). There was no statistically significant difference in partial pressure of end-tidal carbon dioxide (PCO 2) and arterial carbon dioxide partial pressure (PaCO 2) between the two groups (both P < 0.05). At 15 minutes after pneumoperitoneum, the PaCO 2 level increased in each group, and the PaCO 2 level in the observation group was significantly higher than that in the control group (all P < 0.05). At the same time, the HCO 3- level decreased in each group, and the HCO 3- level in the observation group was significantly lower than that in the control group (all P < 0.05). At 5 minutes before recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the control group were (76.52 ± 8.61) beats/minute, (113.52 ± 5.36) mmHg (1 mmHg = 0.133 kPa), and (86.91 ± 4.21) mmHg, respectively. At 5 minutes after recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the control group were (89.52 ± 8.61) beats/minute, (106.85 ± 5.63) mmHg, and (80.96 ± 3.65) mmHg, respectively. At 5 minutes before recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the observation group were (76.36 ± 8.61) beats/minute, (112.79 ± 5.28) mmHg, and (86.89 ± 4.54) mmHg. At 5 minutes after recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the observation group were (75.63 ± 6.86) beats/minute, (111.99 ± 5.51) mmHg, and (85.06 ± 3.21) mmHg, respectively. At 5 minutes after recovery of body position, heart rate in the control group was increased and that in the observation group was decreased compared with heart rate measured at 5 minutes before recovery of body position. At 5 minutes after recovery of body position, heart rate in the observation group was significantly lower than that in the control group. Diastolic blood pressure and systolic blood pressure decreased in each group, and the amplitudes of reductions in diastolic blood pressure and systolic blood pressure in the observation group were significantly lower than those in the control group. ( t = 6.04, 3.26, 4.22, all P < 0.05). There was no statistically significant difference in incidence of adverse reactions between the two groups ( P > 0.05). The overall response rate in the observation group was significantly higher than that in the control group ( P < 0.05). Conclusion:Compared with conventional lithotomy position total laparoscopic hysteretsotomy, high and low lithotomy position total laparoscopic hysterectomy takes a shorter duration for total laparoscopic hysterectomy, leads to a shorter length of hospital stay, results in less blood loss, causes fewer postoperative infections, and results in more stable hemodynamics and a lower incidence of complications.

A Comparative Study of the Energy Contribution Characteristics between 1500 m Speed Skating and Cycling Maximal Exercise / 中国运动医学杂志

Objective To explore the differences in energy contribution between 1500 m speed skat-ing and cycling maximal exercise.Methods Eleven professional skaters took the tests of 1500 m speed skating and cycling maximal exercise,respectively.A portable gas analyzer and a blood lactate analyz-er were used to measure and assess the gas metabolism during and 6 minutes after the tests,along with the blood lactate level before and after them.The energy contribution and contribution rates were calculated by using the phosphoric acid-lactic acid-oxygen method.Results There were significant dif-ferences between the two tests in the average accumulated oxygen uptake(5.52±0.99 L vs 5.94±0.75 L,P=0.043,ES=0.481)and the rapid recovery of oxygen uptake after exercise(2.07±0.67 L vs 1.52±0.86 L,P=0.029,ES=0.746).However,no significant differences were found in the rela-tive anaerobic lactic contribution between the two different exercises.Moreover,the relative anaerobic alactic contribution of speed skating was significantly greater than cycling(21.36%±4.12%vs 15.39%±5.89%,P=0.010,ES=1.211),while the relative aerobic contribution was significantly lower than the latter(52.31%±5.45%vs 57.13%±5.12%,P=0.016,ES=0.913).Conclusions The energy contri-bution of 1500 m speed skating is different from the cycling maximal exercise,indicating that the rel-ative aerobic contribution differs among different exercises.Therefore,future training plans should be tailored to the specific energy contribution characteristics of each sport and speed skaters should strengthen their explosive training when taking cycling as the main training method in non-ice periods.

Objective:To investigate the clinical significance of prognostic serum marker expression in older adult patients with sepsis-associated encephalopathy (SAE).Methods:The clinical data of 79 older adult patients with SAE who received treatment in The Second People's Hospital of Hefei from June 2019 to February 2021 (study group) and 121 sepsis patients without encephalopathy concurrently (control group) were retrospectively analyzed. The indexes with statistically significant difference between the two groups were subjected to multivariate binary logistic regression. Survival curve was plotted.Results:There were no significant differences in neuron specific enolase [NSE, (10.69 ± 4.31) μg/L vs. (24.84 ± 3.28) μg/L, t = 26.25, P < 0.01], S100β [(0.25 ± 0.06) μg/L vs. (0.53 ± 0.09) μg/L, t = 22.45, P < 0.01], monocyte chemoattractant protein-1 [MCP-1, (99.33 ± 4.87) ng/L vs. (179.99 ± 6.02) ng/L, t = 99.94, P < 0.01], malondialdehyde [MDA, (4.22 ± 0.08) nmol/L vs. (6.78 ± 0.11) nmol/L, t = 33.76, P < 0.01], glial fibrillary acidic protein [GFAP, (0.21±0.08) μg/L vs. (2.03 ± 0.47) μg/L, t = 33.76, P < 0.01], procalcitonin [(7.04 ± 2.50) ng/L vs. (16.23 ± 2.48) ng/L, t = 25.47, P < 0.01], interleukin-6 [(29.91 ± 4.51) ng/L vs. (69.22 ± 6.79) ng/L, t = 45.51, P < 0.01], Acute Physiology and Chronic Health Evaluation II (APACHE II) score [(18.33 ± 2.12) points vs. (28.89 ± 5.09) points, t = 17.53, P < 0.01], and sequential organ failure assessment score [(7.69 ± 1.50) points vs. (14.05 ± 1.55) points, t = 28.92, P < 0.01] between the control and study groups. N-terminal pro B-type natriuretic peptide was (868.38 ± 25.28) ng/L and (1 037.19 ± 25.34) ng/L in the control and study groups, respectively. Logistic regression analysis revealed that NSE, MCP-1, MDA, and GFAP were the independent risk factors for developing SAE in older adults (NSE: t = 8.42, P < 0.01; MCP-1: t = 4.16, P < 0.01; MDA: t = 18.4, P < 0.01; GFAP: t = 2.88, P < 0.01). The survival curve indicated that survival rate was significantly lower in the study group than in the control group. Conclusion:NSE, MCP-1, MDA, and GFAP are independent risk factors for developing SAE in older adults.

Prevalence and risk factors of hypertensive retinopathy in a health-checkup population / 中华健康管理学杂志

Objective:To investigate the prevalence and risk factors of hypertensive retinopathy (HRP) in a non-diabetic population over 30 years old during routine health examinations.Methods:This was a cross-sectional study of a non-diabetic population over 30 years of age. The study was conducted during routine health examinations at the Tongren Hospital, Beijing, from January to December 2020. Fundus photographs were taken, and data including medical history, height, weight, and blood pressure were collected. Routine laboratory examinations were performed. The study population was divided into hypertension, transient hypertension, and non-hypertension groups. The prevalence of HRP was compared among the three groups. OR and 95% CI of HRP risk factors was estimated by binary logistic regression, adjusted for age and gender. Results:The prevalence of HRP was 4.3% in the non-diabetic population over 30 years old. Adjusted for age, gender, and systolic blood pressure, the prevalence of HRP in hypertension and transient hypertension groups, was both higher than in the non-hypertension group [ OR(95% CI) of 3.11(2.25-4.30) and 1.72(1.21-2.45), respectively]. The proportion of grade 1-2 HRP was higher (76.2%). There was no significant difference in the prevalence of grade 3 HRP among the three groups. Adjusted for age and gender, systolic blood pressure and creatinine clearance rate were independent risk factors for HRP in the hypertension group [ OR(95% CI): 1.22(1.01-1.48) and 1.66(1.12-2.46)] and transient hypertension group [ OR(95% CI): 1.48(1.10-2.06) and 1.95(1.03-3.46)]. SBP and DBP were independent risk factors for HRP in the non-hypertension group [ OR(95% CI): 1.68(1.07-2.63) and 1.61(1.06-2.44)]. Conclusions:There was a high prevalence of HRP among the non-diabetic population over the age of 30 and there was still relatively high risk of grade 3 HRP among the normotensive population.

Stasis Caused by Depression and Coronary Heart Disease / 中国实验方剂学杂志

Anxiety and depression are common comorbidities of coronary heart disease and are considered as independent risk factors in addition to traditional cardiovascular risk factors. Anxiety，depression and other mental abnormalities belong to the category of "depressive syndrome" of traditional Chinese medicine，which can lead to stasis of blood due to the lack of Qi flow. "Blood stasis" involves abnormal blood rheology， vascular endothelial dysfunction， chronic inflammatory response， abnormal lipid metabolism and other comprehensive pathological changes， and is the core pathogenesis of coronary heart disease in traditional Chinese medicine. "Depressive syndrome"can aggravate the development of coronary heart disease by promoting blood stasis in multiple ways. Prescriptions and herbs of promoting blood circulation and removing blood stasis can have a clinical effect by promoting blood circulation （improving physiological functions） and removing blood stasis （eliminating pathological changes）. In clinical practice， strengthening the screening of the mental and psychological status of patients with coronary heart disease and providing early and effective psychological interventions and combined Chinese and Western medicine drug treatment can significantly improve the clinical symptoms and prognosis of patients. This article was the first to put forward the academic view of "stasis caused by depression" for the first time，and discuss the modern biological research progress of "depression" in Chinese medicine that promotes blood stasis and aggravates coronary heart disease，in order to provide a basis for the subsequent development of Chinese medicine in the prevention and treatment of coronary heart disease. The aim is to provide a theoretical basis for the subsequent systematic research on the prevention and treatment of coronary heart disease with emotional abnormalities in Chinese medicine.

Guidelines investigation and technical considerations of virus safety during investigational new drug application of innovative monoclonal antibody products / 药学学报

With the development of antibody manufacturing technology and improvement of new drug research in domestic industry, more innovative monoclonal antibody products submitted investigational new drug (IND) application. At the same time, monoclonal antibody products from abroad which have been approved marketing authorization and/or conducted clinical trials submitted IND applications in China. The National Medical Products Administration (NMPA) issued the "Guideline of Investigational New Drug Application" (No. 16, 2018) which emphasized the chemical, manufacturing, and control (CMC) regulatory, and dossier requirements in IND application, greatly promoted the application quality of innovative biological products. However, compared to the Food and Drug Administration (FDA) and European Medicines Agency (EMA), our particular guidelines are insufficient, such as guideline on virus safety evaluation of biotechnological investigational medicinal products. This review investigated the questions raised by sponsors from 2018 to 2020, including the end of production cell (EOPC) and/or unprocessed bulk (UPB) testing and virus removal or inactivation validation. Meanwhile, sponsors submitted different dossiers due to differences in understanding of stage requirements of guidelines from domestic and abroad. Based on the guidelines of virus safety from NMPA, FDA, and EMA, and the technical considerations, this review puts forward personal suggestions on the adventitious agents testing and virus removal or inactivation validation in manufacturing process, aim to ensure virus safety of innovative monoclonal antibody products in clinical trials.

Asymptomatic COVID-19 infection in pregnant woman in the third trimester: a case report / 中华围产医学杂志

We report a case of asymptomatic COVID-19 infection in a pregnant woman in the third trimester with good maternal and infant outcomes. The patient was admitted to the Second People's Hospital of Hefei on February 11, 2020, because of a "positive novel coronavirus nucleic acid test result for one day" at 38 weeks of gestation. No abnormality was observed during her previous regular prenatal examinations. A throat swab sample was obtained from the patient four days before admission due to the diagnosis of COVID-19 infection in her husband and sister on the 14th and 7th day before her admission, and the new coronavirus nucleic acid test showed positive. The patient reported no discomfort before admission. Chest CT on the 3rd after admission showed a small amount of bilateral pleural effusion. Irregular contractions occurred three days after admission and labor was considered to be imminent. An emergency cesarean section was performed and the patient delivered a live baby girl. No tests were performed on amniotic fluid, cord blood or placenta for new coronavirus nuclei acid. The patient was isolated from the infant without breastfeeding after surgery. All medical staff involved in the cesarean section were isolated after surgery. Neonatal peripheral blood and nasopharyngeal swabs were collected for the new coronavirus nucleic acid tests on the day of birth and one day of age respectively, and nasopharyngeal swabs and anal suabs were taken at nine days after birth. All test results were negative. The patient recovered well after surgery with stable vital signs. Chest CT on the 8th after operation showed a small amount of bilateral pleural effusion, while the new coronavirus nucleic acid test results of the pharyngeal swabs were positive on the 11th and 12th day after operation. The throat swabs of all medical staff involved in the operation were negative 14 days after the operation. The mother and baby were discharged 14 days after the Cesarean section.

Analysis of the results of hearing screening in physical examination in Beijing / 中华健康管理学杂志

Objective:To investigate the prevalence and characteristics of adult hearing loss.Methods:From March 2018 to November 2019, 8, 439 adult physical examinees were screened for hearing (i.e., 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz pure tone air conduction audiometry), while some were examined for hearing diagnosis (i.e., 250 Hz, 500 Hz, 1, 000 Hz, 2, 000 Hz, 4 000 Hz, and 8 000 Hz pure tone bone air conduction audiometry). Prevalence, location, frequency and type of hearing loss in different age and gender groups were analyzed using SPSS 25.0.Results:The prevalence of hearing loss was 32.2%, which increased with age. The prevalence in males was higher than that of females (40.1% vs. 21.6%). The rate of single frequency damage was higher in male than in female, while the rate of multiple frequency damage was higher in women than in men ( P<0.001). The high frequency (4 000 Hz) damage rate in male was higher than that of females, while the low-middle frequency (500-2 000 Hz) damage rate in females was higher than that of males ( P<0.001). Sensorineural hearing loss accounted for 90.8%, while conductive hearing loss was 3.9%, mixed hearing loss was 5.0%, and others were 0.3%. Conductive hearing loss was mainly concentrated in the younger age group. Conclusion:Physical examination population has a relatively high prevalence of hearing loss. The characteristics of hearing loss differed with age and gender.
