Abstract
In ancient times, the original plants of Citri Exocarpium Rubrum and Citri Grandis Exocarpium had experienced succession and change, including tangerine(Citrus reticulata), pomelo(C. grandis), and Huazhou pomelo(C. grandis 'Tomentosa'), a specific cultivar of C. grandis produced in Huazhou, Guangdong. Before the Qing Dynasty, tangerine was the main original plant, while Huazhou pomelo came to the fore in the Qing Dynasty. In the 1950 s and 1960 s, the producing area of Huazhou pomelo was destroyed, and thus it had to be supplemented with pomelo. From then on, C. grandis 'Tomentosa' and C. grandis were both listed as the original plants of Citri Grandis Exocarpium in the Chinese Pharmacopoeia. This paper reviewed the historical evolution of the collection, processing, and efficacy of Citri Exocarpium Rubrum and Citri Grandis Exocarpium. The research showed that:(1)The harvest time of the original plants of Citri Grandis Exocarpium and Citri Grandis Exocarpium had changed from maturity to immaturity. The collection and processing of Citri Exocarpium Rubrum was first recorded in the Illustrated Classics of Materia Medica in the Song Dynasty. During the Ming and Qing Dynasties, the mesocarp of Citri Exocarpium Rubrum needed to be removed completely, and Citri Grandis Exocarpium from C. grandis 'Tomentosa' was processed into different specifications such as seven-piece, five-piece, and single piece. Furthermore, processed young fruits of Huazhou pomelo appeared.(2)Citri Exocarpium Rubrum and Citri Grandis Exocarpium were processed with carp skin for the first time in the Master Lei's Discourse on Medicinal Processing. It was suggested that carp skin might be helpful for eliminating bones stuck in throat. During the Song, Jin, and Yuan Dynasties, some other processing methods such as ba-king, stir-frying, and salt-processing appeared. Honey, soil, ginger juice, and alum were firstly used as adjuvants for the processing in the Ming and Qing Dynasties. Citri Exocarpium Rubrum was mainly prepared with salt in order to improve the effect of lowering Qi, while it was unnecessary for Citri Grandis Exocarpium from C. grandis 'Tomentosa' because of its obvious effect of lowering Qi and eliminating phlegm. The stir-frying and honey-frying methods helped reduce the strong effect of Citri Grandis Exocarpium from C. grandis 'Tomentosa'.(3)According to the application of Citri Exocarpium Rubrum and Citri Grandis Exocarpium in history, their medicinal use began in Han and Tang Dynasties, developed in Song, Jin, and Yuan Dynasties, and matured in Ming and Qing Dynasties. Citri Grandis Exocarpium from C. grandis 'Tomentosa' was originally applied in Ming and Qing Dynasties, and it still plays an important in role treating COVID-19 nowadays. Moreover, Citri Grandis Exocarpium from C. grandis had cold medicinal property, while Citri Grandis Exocarpium from C. grandis 'Tomentosa' had warm medicinal property, and thus they should not be treated the same. At present, Huazhou pomelo has a certain production scale. Therefore, it is recommended that in the next edition of Chinese Pharmacopoeia, only C. grandis 'Tomentosa' should be included as the original plant of Citri Grandis Exocarpium, and C. grandis should be deleted. The results are conducive to the further development and utilization of Citri Exocarpium Rubrum and Citri Grandis Exocarpium, and support the rational use of Citri Grandis Exocarpium and its processed products.

Abstract
Objective: To analyze the sensitivity and specificity of SARS-CoV-2 nucleic acid testing in 20 348 close contacts of COVID-19 cases in different prevention and control stages in Guangzhou and to provide scientific evidence for optimizing epidemic response strategies. Methods: A total of 20 348 close contacts of COVID-19 cases in Guangzhou were traced between February 21 and September 22,2020. All the close contacts were tested for the nucleic acid of SARS-CoV-2. The sensitivity and specificity of nucleic acid testing and diagnosis in the different prevention and control stages were compared. Results: In 20 348 close contacts, 12 462 were males (61.24%), the median (P25,P75) of age of them was 31.0 years (23.0,43.0), the median number (P25,P75) of nucleic acid testing for them was 2.0 (1.0,3.0), and the median (P25,P75) of their quarantine days was 12.0 (8.0,13.0) days, respectively. A total of 256 COVID-19 cases were confirmed in the close contacts after seven nucleic acid tests. In the 1st, 2nd, 3rd and 7th nucleic acid testing, the sensitivity and specificity were 69.14% and 99.99% (177 cases confirmed), 89.84% and 99.99% (230 cases confirmed), 97.27% and 99.99% (249 cases confirmed), and 100.00% and 99.98%, respectively. In the three stages of COVID-19 prevention and control in China: domestic case stage, imported case stage, and imported case associated local epidemic stage, the sensitivity of the 1st nucleic acid testing was 70.68%, 68.00% and 67.35%, and the specificity was 99.98%, 100.00% and 100.00%, respectively. Conclusions: The sensitivity of nucleic acid testing in the close contacts at the different stages were consistent with slight decrease, which might be related to the increased proportion of asymptomatic infections in the late stage of epidemic prevention and control with COVID-19 in Guangzhou. It is suggested to give three nucleic acid tests to improve the sensitivity and reduce false negative risk.

Abstract
Objective: To analysis of high-frequency hearing loss status and risk factors among male noise workers in an automobile manufacturing enterprise in Guangzhou. Methods: From February 2020, a cluster sampling method was used to select 3486 male workers exposed to noise in an automobile manufacturing enterprise in Guangzhou in 2018. After screening, 2608 were selected as the research objects. Pure tone hearing threshold test, noise exposure level test and questionnaire survey were conducted, and the cumulative noise exposure was calculated. Chi square test and unconditional logistic regression were used to analyze the correlation between various factors and high frequency hearing loss. Results: The detection rate of high-frequency hearing loss in noise exposed workers was 34.20% (892/2608) , there were significant differences in the two groups among age, marital status, years of noise exposure, noise exposure equivalent A sound level, CNE, different working hours and exposure to electromagnetic radiation (P<0.05) . Multiple logistic regression analysis showed that age, CNE and exposure to electromagnetic radiation were independent risk factors for high-frequency hearing loss (P<0.05) , three shifts and two shifts were the protective factors for the occurrence of high-frequency hearing loss (OR=0.523, P<0.01) . Conclusion: Noise exposure is the main influencing factor of high-frequency hearing loss of noise-receiving workers in automobile manufacturing enterprises. Enterprises should strengthen noise control in the workplace, improve the working environment of electromagnetic radiation, and implement a scientific and healthy work shift system.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Toxicodendron vernicifluum (Stokes) F.A. Barkley (syn. Rhus verniciflua or vernicifera Stokes, Anacardiaceae) (RVS), the lacquer tree, also known as sumac, has been used in China, Japan and South Korea for thousands of years as a highly durable coating material and a traditional herbal medicine, which contains medicinal ingredients with anti-tumor, anti-inflammatory, antiviral, and anti-rheumatic activities. AIM OF THIS REVIEW This review intends to provide a comprehensive and critical appraisal of RVS, including its phytochemical data, botanical and pharmacological literature that support its therapeutic potential in treatment on human diseases, with emphasis on the isolation of natural occurring compounds and detailed pharmacological investigations. MATERIALS AND METHODS Specific information of RVS was collected by using the key words "Toxicodendron vernicifluum", "Rhus verniciflua Stokes", "Rhus vernicifera Stokes" and "Lacquer tree" through published scientific materials (including PubMed, ScienceDirect, Wiley, ACS, CNKI, Scifinder, Springer, Web of Science, Google Scholar, and Baidu Scholar) and other literature sources. RESULTS The major phytoconstituents, 175 of which are presented in this review, including flavonoids, urushiols, terpenes, phenolic acids and other types of compounds, of which flavonoids and urushiols are main components. The extracts and isolates purified from RVS showed a wide range of in vitro and in vivo pharmacological effects, such as anti-cancer, anti-oxidation, anti-inflammatory, antimicrobial, tyrosinase inhibition and so on. CONCLUSION The modern pharmacological research of RVS mainly focus on the pharmacological effects of crude extract or active constituents, of which the flavonoids are widely studied. However, there are few reports on the relationship between pharmacological effects and their structures. And at present, there is still a lack of researches that are of both effective and in-depth. Meanwhile, there is little research on quality control. Apart from the wood and lacquer, other botanical parts also need to be explored further. In addition to phenolic compounds, the study on other types of components in T. vernicifluum would start more sparks for the discovery of new bioactive principles.

Abstract
Objective: To understand the epidemiological characteristics of imported COVID-19 cases in Guangzhou and provide scientific basis for the prevention and control of the disease. Methods: The data of imported COVID-19 in Guangzhou reported as of April 1, 2020 were collected from National Notifiable Disease Report System of China. The software Excel 2010 and SPSS 19.0 were applied for data cleaning and statistical analysis. Results: As of April 1, 2020, a total of 103 imported COVID-19 cases had been reported in Guangzhou, in which 92 were confirmed cases and 11 were asymptomatic infection cases. The number of the confirmed imported cases accounted for 11.4% (92/806) in of the total in China at the same time. The male to female ratio of the cases was 1.58∶1 (63∶40). The median age of the cases was 31 years (P(25)-P(75):22-40 years), range of age was 11-63 years. The main occupational distributions of the cases were business services (41/103, 39.8%) and students (36/103, 35.0%). The imported cases whose destinations were 19 provinces and municipalities rather than Guangdong after entering the country accounted for 43.7%. The main source countries of infections were the United Kingdom (27/103, 26.2%), the Philippines (13/103, 12.6%), the United States (13/103, 12.6%) and Nigeria (7/103, 6.8%). There were 34 inbound flights from which the imported COVID-19 cases were detected, in which 10 flights (10/34, 29.4%) were found to carry more than 3 cases, with an average voyage time of (11.14±0.53) hours. A total of 29 imported cases(28.2%) showed symptoms before entering the country, and 65 cases (63.1%) had been isolated before the onset of the disease. The mean free activity time of the isolated cases after the onset was (6.76±0.79) days. The average number of the imported cases' close contacts was 53. There were 13 clusters of COVID-19 caused by the imported cases, involving 36 cases (including 1 imported associated case). Conclusions: The sources of the imported COVID-19 cases in Guangzhou were widely distributed, and no cases had been found to be infected on the flights. In the early stage of the imported epidemic, there was high risk for the spread of the epidemic. Strengthened prevention and control of imported COVID-19 effectively reduced the of transmission risk of COVID-19 in communities.

Abstract
Objective: To understand the prevalence of gynecologic diseases among married female workers. Methods: The data of married female workers who underwent occupational health examination in a physical examination center from January to December 2017 were collected. The relationship between the detection of common gynecological diseases, age and occupational types examined by gynecological routine, TCT, breast B-mode ultrasound, uterus and appendix B-mode ultrasound were analyzed. Results: Among the 1142 female workers, the total detection rate of reproductive tract infections was 67.25% (768/1142), the total detection rate of breast-related diseases was 75.22% (859/1142) ; the total detection rate of gynecological tumors and benign lesions was 14.71% (168/1142). The detection rate of breast hyperplasia was the highest 67.08% (766/1142), followed by vaginitis 51.66% (590/1142). Among the abnormalities detected in breast-related diseases, gynecological tumors and benign lesions, the highest detection rate was found in public institutions (85.66% and 27.13%), and the lowest was found in factory workers (70.24% and 7.89%). With the increase of age, the detection rate of breastrelated diseases (breast hyperplasia, breast cyst), gynecological tumors, benign lesions (uterine myoma), and Nessler's cyst abnormalities in married female workers increased (χ(2)(trend)=7.647、21.653、107.411、53.802, P<0.05), while the detection rate of columnar epithelium of cervix decreased (χ(2)(trend)=7.404, P<0.05). There was no significant difference in the total detection rate of reproductive tract infectious diseases (vaginitis, cervical polyps, cervical hypertrophy) among married famale workers of different ages (P<0.05) . Conclusion: The common gynecological diseases of married female workers are affected by many factors such as age and occupation. Health examination and health education should be carried out regularly to reduce the incidence of gynecological diseases among female workers according to different ages and occupations.

Abstract
Objective: To investigate the prevalence of work-related musculoskeletal disorders (WMSDs) in male welders in different work areas of shipbuilding industry based on their operational working position and body position characteristics and to analyze the operational positions and ergonomic loads. Methods: In February 2017, 412 male welders from the hull and block work areas of a large ship factory were selected by stratified sampling. The prevalence and effects of WMSDs within a year were investigated using the Nordic Musculoskeletal Disorders Questionnaire, and a rapid exposure checklist was used to obtain the ergonomic load index by comprehensive scoring; the exposure-response relationship between the ergonomic loads and WMSDs symptoms of subjects in the hull and block work areas was evaluated. Results: Among the male welders working in the hull work area of shipbuilding industry, WMSDs occurred more commonly in the neck, lower back/waist, and legs, accounting for 53.16% (126/237) , 51.90% (123/237) , and 41.77% (99/237) , respectively; among those working in the block work area, WMSDs occurred more commonly in the lower back/waist, wrist, and legs, accounting for 52.57% (92/175) , 49.14% (86/175) , and 45.14% (79/175) , respectively. There were significant differences in the distribution of cases of pain within the last 7 days and one month, pain lasting more than one month, or absence from work due to pain within a year in the four positions between the two work areas (P<0.05). In the hull work area, high and extremely high exposure levels were mainly seen in the neck, lower back/waist, and legs, accounting for 76.79%(182/237), 69.20%(164/237), and 59.49%(141/237), respectively; in the block work area, high and extremely high exposure levels were mainly seen in the lower back/waist, wrist, and legs, accounting for 77.71%(136/175), 50.29% (88/175), and 46.29% (81/175), respectively. The detection rates of WMSDs in these four positions significantly increased as the exposure levels rose (P<0.01). Conclusion: The WMSDs of male welders working in the hull and block work areas of shipbuilding industry occurs more commonly in the lower back/waist and legs. The risk of WMSDs symptoms increases with the rise of ergonomic load.

Abstract
In this paper, we propose a human action recognition method using HOIRM (histogram of oriented interest region motion) feature fusion and a BOW (bag of words) model based on AP (affinity propagation) clustering. First, a HOIRM feature extraction method based on spatiotemporal interest points ROI is proposed. HOIRM can be regarded as a middle-level feature between local and global features. Then, HOIRM is fused with 3D HOG and 3D HOF local features using a cumulative histogram. The method further improves the robustness of local features to camera view angle and distance variations in complex scenes, which in turn improves the correct rate of action recognition. Finally, a BOW model based on AP clustering is proposed and applied to action classification. It obtains the appropriate visual dictionary capacity and achieves better clustering effect for the joint description of a variety of features. The experimental results demonstrate that by using the fused features with the proposed BOW model, the average recognition rate is 95.75% in the KTH database, and 88.25% in the UCF database, which are both higher than those by using only 3D HOG+3D HOF or HOIRM features. Moreover, the average recognition rate achieved by the proposed method in the two databases is higher than that obtained by other methods.

Abstract
Powdery mildew (Pm) is one of the most harmful diseases in wheat. Three Pm-resistance genes, Pm3, Pm21, and Pm8, have been cloned but most Pm3/Pm8 alleles have lost their resistance to Pm in hexaploid wheat. In this study, a new Pm3 homolog gene (TmPm3) was isolated from Triticum monococcum L. using a homology-based cloning strategy, being the first report of a functional Pm3 homolog gene from a diploid wheat species. The transient expression of TmPm3 in leaf epidermal cells showed that over-expressed TmPm3 could significantly inhibit the penetration of Blumeria graminis f. sp tritici conidia spores and the formation of haustoria. Sequence analysis of Pm3 alleles shed new light on the evolution of Pm3 genes, providing a better understanding of the molecular basis of disease resistance. This study also suggested that homology-based cloning of resistance genes is a feasible method for the isolation of functional resistance genes from wheat germplasm.

Abstract
BACKGROUND AND OBJECTIVE The proteasome inhibitor, bortezomib, is known to induce osteoblastic differentiation in a number of cell lines, such as mesenchymal stem cells and osteoblastic precursor cells. As periodontal ligament (PDL) cells are multipotent, we examined whether bortezomib may induce the differentiation of PDL cells into hard-tissue-forming cells. MATERIAL AND METHODS A mouse PDL clone cell line, MPDL22 cells, was cultured in mineralization medium in the presence or absence of bortezomib. Expression of calcification-related genes and calcified-nodule formation were evaluated by real-time PCR and Alizarin Red staining, respectively. RESULTS Bortezomib increased the expression of calcification-related mRNAs, such as tissue nonspecific alkaline phosphatase isoenzyme (ALPase), bone sialoprotein (Bsp), runt-related transcription factor 2 (Runx2) and osteopontin, and calcified-nodule formation in MPDL22 cells. These effects were induced, in part, by increasing the cytosolic accumulation and nuclear translocation of β-catenin, leading to an increase in expression of bone morphogenetic protein (Bmp)-2, -4 and -6 mRNAs. In addition, bortezomib enhanced BMP-2-induced expression of Bsp and osteopontin mRNAs and increased calcified-nodule formation in MPDL22 cells. CONCLUSION Bortezomib induced cytodifferentiation and mineralization of PDL cells by enhancing the accumulation of β-catenin within the cytosol and the nucleus and increasing the expression of Bmp-2, -4 and -6 mRNAs. Moreover, bortezomib enhanced the BMP-2-induced cytodifferentiation and mineralization of PDL cells, suggesting that bortezomib may be efficacious for use in periodontal regeneration therapy.

Abstract
MicroRNAs (miRNAs) are small RNA molecules that modulate gene expression implicated in cancer, which play crucial roles in diverse biological processes, such as development, differentiation, apoptosis, and proliferation. The aim of this study was to investigate whether miR-30c mediated the resistance of breast cancer cells to the chemotherapeutic agent doxorubicin (ADR) by targeting tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (YWHAZ). miR-30c was downregulated in the doxorubicin-resistant human breast cancer cell lines MCF-7/ADR and MDA-MB-231/ADR compared with their parental MCF-7 and MDA-MB-231 cell lines, respectively. Furthermore, we observed that transfection of an miR-30c mimic significantly suppressed the ability of MCF-7/ADR to resist doxorubicin. Moreover, the anti-apoptotic gene YWHAZ was confirmed as a target of miR-30c by luciferase reporter assay, and further studies indicated that the mechanism for miR-30c on the sensitivity of breast cancer cells involved YWHAZ and its downstream p38 mitogen-activated protein kinase (p38MAPK) pathway. Together, our findings provided evidence that miR-30c was one of the important miRNAs in doxorubicin resistance by regulating YWHAZ in the breast cancer cell line MCF-7/ADR.

Abstract
Powdery mildew caused by Erysiphe graminis f. sp. tritici is one of the most important wheat diseases in many regions of the world. Breeding for resistant cultivars has been proved to be an effective and environmentally safe method to control diseases in wheat production. It is necessary to search for more resistance genes for the diversification of resistance genes in wheat breeding. An Isreali wild emmer wheat (Triticum dicoccoides) accession "G-305-M" was found resistant to the prevailing E. graminis f. sp. tritici isolate Race No. 15 in Beijing region. The powdery mildew resistance has been transferred from G-305-M into common wheat by crossing and backcrossing (G-305-M/781//Jing 411* 3). Genetic analysis showed that the resistance was controlled by a single dominant gene at the seedling stage. A segregating BC2F3 family of the cross "G-305-M/781//Jing 411* 3" with 167 plants was chosen for SSR analysis. Totally 96 wheat microsatellite primer pairs were screened, only one primer pair WMS570 could generate polymorphic DNA fragments between the resistant and susceptible plants. After evaluating this polymorphic marker in the segregating population, the microsatellite locus Xgwm570 mapped on chromosome 6AL was found to be linked to the resistance gene, with the estimated genetic distance of 14.9 +/- 3.0 cM. Based on the origin and chromosomal location of the gene, it is suggested that the resistance gene derived from G-305-M should be a novel Pm gene and is temporarily designated MlG.
