By systematically combing ancient and modern literature， this paper examined Tribuli Fructus and Astragali Complanati Semen（ACS） used in the famous classical formulas from the aspects of name， origin， production area， harvesting and processing， clinical efficacy， so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology， and there were nicknames such as Baijili， Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas， and there were nicknames such as Baijili， Shayuan Jili and Tongjili. Because both of them had the name of Baijili， confusion began to appear in the Song dynasty. In ancient and modern times， the main origin of Tribuli Fructus were Tribulus terrestris， and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu， but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part， harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times， and the plump， firm texture， grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing， while modern commonly used is purified， fried and salt-processed. The ancient records of Tribuli Fructus were spicy， bitter， and warm in nature， with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders， improving vision， promoting muscle growth， and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today， the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed， traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter， followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior， while modern standards prioritize plump， uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying， while modern practice commonly employs purification methods. In terms of medicinal properties， the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus， its effects were thus regarded as equivalent to those of Tribuli Fructus， serving as the medicine for treating wind disorders， additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang， solidify sperm and reduce urine， nourish the liver and brighten the eye， etc. Based on the textual research results， it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials， we should pay attention to the specific reference object of Baijili， T. terrestris and A. complanatus should be identified and selected， and the processing method should be in accordance with the requirements of the formulas.

Objective To analyze the clinical characteristics and related to risk factors of late-life depression patients with venous thromboembolism in the elderly ward.Methods A retrospective analysis was conducted on 143 hospitalized depression patients(aged≥60 years)including 65 depression patients with VTE(VTE group)and 78 depression patients without VTE(control group)in the elderly ward of Beijing Anding Hospital from January 2023 to September 2023.The clinic and laboratory data was collected such as general demographic information,relevant clinical data,VTE history,personal history,thyroid function,hormone levels,blood lipid levels and D-dimer to analyze and compare the clinical characteristics of two group patients,and Logistic regression was used to analyze the related risk factors of VTE in patients with depression.Results Compared with control group,patients in the VTE group were older[(70.94±5.88)years vs.(68.04±4.92)years,P<0.05],had a higher total HAMD score(26.35±9.28 vs.23.19±5.94,P<0.05),a higher proportion of a history of VTE[13 cases(20.0%)vs.6 cases(7.7%),P<0.05],a higher proportion of bedridden for more than 72 hours[42 cases(64.6%)vs.31 cases(39.7%),P<0.05],lower HDL-C levels[(1.27±0.27)mmol/L vs.(1.39±0.28)mmol/L,P<0.05],and higher levels of D-dimer[1.91(0.82,3.51)mg/L FEU vs.0.48(0.25,0.80)mg/L FEU,P<0.05].Logistic regression analysis showed that total HAMD scores(OR=1.077,P=0.018),history of VTE(OR=4.339,P=0.023),bedridden for more than 72 hours(OR=2.449,P=0.044),and D-dimer level(OR=2.404,P<0.001)were risk factors for hospitalized late-life depression patients with VTE in the elderly ward.Conclusions Depression patients with VTE in the elderly ward have several clinical characteristics including older age,more severe depressive symptoms,lower HDL-C levels,higher D-dimer levels,and higher proportion of a history of VTE and bedridden for more than 72 hours.Depressive symptoms,a history of VTE,bedridden for more than 72 hours,and D-dimer levels may be risk factors for late-life depression patients with VTE in the elderly ward.

OBJECTIVE To analyze the traditional Chinese medicine （TCM） emergency management policy texts in China， reveal the characteristics， problems and improvement directions of Chinese medicine emergency management policies in China， and provide references and lessons for improving the level of Chinese medicine emergency management. METHODS Twenty-four TCM emergency management policy texts issued at the central level from 2016 to 2023 were coded and analyzed using Nvivo11 software to construct a three-dimensional analysis framework based on policy tools， stakeholders and policy strength. RESULTS In the policy tools dimension， the environmental type was the most （46.74%）， the supply type was the second （31.80%）， and the demand type was the least （21.46%）； in the stakeholder dimension， there were more healthcare institutions （40.63%） and government departments （31.25%）， and fewer healthcare workers （14.84%） and residents （13.28%）； in the policy strength dimension， the overall policy strength was poor， and the differences in effectiveness across policy instruments and stakeholders were more significant. The cross-cutting results showed that there was a certain degree of mismatch in policy instruments， stakeholders and policy strength. CONCLUSIONS The use of supply-oriented policy tools is slightly lacking， and the use of policy tools should be optimized in a coordinated manner； the distribution of stakeholders is relatively unbalanced， and synergies among stakeholders should be enhanced； the overall strength of policies is poor， and the top-level design of relevant policies should be improved.

Objective:To investigate the clinical features and prognosis of male with anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody.Methods:The clinical data of 246 patients with DM and anti-MDA5 autoantibodies hospitalized by Jiangsu Myositis Cooperation Group from 2017 to 2020 were collected and retrospectively analyzed. Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

Objective:To analyze the health literacy level among medical staff and its influencing factors.Methods:Using the convenient sampling method, the in-service medical staff from four medical institutions (Shanghai Pudong New Area People′s Hospital, Shanghai Pudong New Area Zhoupu Hospital, Shanghai Tenth People′s Hospital Chongming Branch, and Shanghai Jing′an District Zhabei Central Hospital) were administered with a national residents′ health literacy questionnaire uniformly compiled by the China Health Education Center, and an electronic questionnaire independently compiled in combination with professional characteristics of the medical staff. The survey period was January 5-17, 2021. The contents of the questionnaire included basic information regarding gender, age, education, and professional title. Respondents were also asked whether they had chronic diseases, and three aspects of health literacy for basic knowledge and concepts, healthy lifestyle and behavior and health skills covering six other types of health problems including scientific outlook on health, infectious disease prevention and control literacy, chronic disease prevention and control. Safety and first aid literacy, basic medical literacy, health information literacy were also assessed. The total score for the questionnaire was 100 points. Respondents with a score of 80 or more were considered to have a competent health literacy. A total of 870 questionnaires were distributed, excluding incomplete ones, 826 valid questionnaires were used for analysis. Logistic regression was used to analyze factors influencing the health literacy among medical staff.Results:The overall health literacy level of medical staff was 64.0%, with 79.7% of respondents indicating that they had basic knowledge and concepts, 70.8% indicating that they practiced healthy lifestyles and behaviors, and 33.5% showed proficiencies in terms of health skills. From high to low, the health literacy levels for the six types of health problems were safety and first aid literacy (80.5%), scientific outlook on health (76.4%), infectious disease prevention and control literacy (60.2%), chronic disease prevention and control literacy (70.9%), basic medical literacy (52.7%), and health information literacy (50.2%). The results of a multivariate logistic regression analysis showed that physical condition, a lifestyle harmful to one′s health, highest educational background, and a professional title in the previous year were the independent influencing factors related to health literacy ( P<0.05). Conclusion:Levels of health skills, basic medical literacy, and health information literacy among medical staff are low, and physical condition in the previous year, lifestyle, professional title, and education are important factors influencing the level of health literacy among medical staff.

Objective:To evaluate the skin development and repair process of X-ray radiation damage in rat with non-invasive two-photon excitation fluorescence (TPEF) imaging technology in vivo. Methods:Totally 24 SD rats were randomly divided into four groups including X-ray irradiated group (25, 35 and 45 Gy) and non-irradiation control group. At different times after irradiation, the degree of skin injury was evaluated, and the pathological changes of nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] and collagen fiber fluorescence signals in epidermal cells were detected in vivo by TPEF imaging technology. Results:At 10 d post-irradiation, the skin of irradiation groups showed erythema and desquamation. At 15-20 d post-irradiation, the skin of radiation groups developed progressive exudation, edema and ulcers with increasing radiation dose. On day 25, the skin began to repair in the 25 Gy group, however, the skin of other groups still had exudation and ulcers. On day 10, NAD(P)H fluorescence signal in epidermal cells of irradiation groups decreased and the fluorescence signal of collagen fibers in papillary layer and reticular layer of irradiation groups reduced, which were significantly lower than that of normal control group ( t=24.145, 28.303, 26.989, 6.654, 7.510, 7.997, P<0.05). On day 30, fluorescence signal of NAD(P)H and collagen fibers in epidermal cells and dermis began to repair, the cell from stratum granulosum, stratum spinosum, and stratum basale in the 25 Gy group showed fluorescence signal, the other groups did not show. The fluorescence signal of collagen fibers in the 25 Gy group were gradually increased in papillary layer and reticular layer, however, they were significantly lower than normal control group ( t=115.133, 17.431, P<0.05), the skin of 45 Gy group did not show fluorescence signal of collagen fibers. Conclusions:The damage and repair process of epidermal cells and dermal collagen fiber can be detected noninvasively by TPEF imaging technology after X-ray irradiation in vivo.

Objective:To compare epidemic characteristics between severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19).Methods:The general information, including epidemiological and clinical data of the confirmed cases during the epidemic period of the two infectious diseases was collected. The data of SARS in Guangzhou was derived from the technical files of Guangzhou Center for Disease Control and Prevention (GZCDC), including the statistical report and brief report of the epidemic situation (from January 2 to May 11, 2003);The data of COVID-19 in Wuhan was derived from the epidemic data published by Wuhan health and Health Committee's official website and other publicly reported documents (from December 9, 2019 to March 11, 2020). Descriptive analysis was used for a comparativeanalysis of the time and age characteristics, the number of cases, basic reproduction number (R0), proportion of medical staff in confirmed cases (%), crude mortality, etc.Results:A total of 1 072 cases of SARS in Guangzhou were included in the study. The incidence ratio of male to female was 1∶1.26. 43 cases of death were reported with a mortality rate of 4.01%. The median age was 36 years old. The proportion of medical staff in the early stage of the epidemic was 29.04% (88 cases). As to COVID-19 in Wuhan, a total of 49 978 cases were included, The incidence ratio of male to female was 1.04∶1. The 2 423 cases of death were reported with a mortality rate of 4.85%. The median age was 56 years old. The proportion of medical staff in the early stage of the epidemic was 30.43% (42 cases).Conclusion:The COVID-19 in Wuhan has the characteristics of high incidence and wide population. However, the epidemic situation is falling rapidly, and the prevention and control strategy needs to be adjusted timely. The prevention and control of nosocomial infection should be addressed in future.

To explore the characteristics of exploratory eye movement (EEM) and hypothalamic-pituitary-adrenal axis (HPA) in elderly patients with acute bipolar and unipolar depression. Methods Thirty-eight elderly patients with bipolar depression (bipolar group) and thirty-nine patients with unipolar depression (unipolar group) were enrolled. The 24-item Hamilton depression rating scale (HAMD-24) was used to evaluate depressive symptoms. The levels of peripheral serum adrenocorticotropic hormone (ACTH) and cortisol (COR) were detected. EEM was recorded to obtain the number of eye fixation (NEF), responsive search score (RSS) and discriminant analysis (D). Results Compared with the unipolar group, the bipolar group had earlier onset, longer duration, and more admissions (P＜0.05). In comparison with the bipolar group, the unipolar group had higher levels of ACTH and COR (P＜0.05), and higher abnormal proportion of COR and ACTH levels. D-values were higher and RSS-values were lower in unipolar group than in bipolar group. There were no significant differences in NEF and HAMD total scores and its subfactors between the two groups (P＞0.05). Correlation analysis showed that the D value of unipolar group was positively correlated with COR level (r=0.482, P=0.002) but not with other indexes (P＞0.05). There were no significant correlations between EEM parameters and serum levels of HPA hormones in bipolar group (P＞0.05). Conclusion There are different clinical features, EEM indicators, the serum levels of ACTH and COR between acute unipolar and bipolar depression, which suggests the heterogeneity between the two diseases.
