Objective: To analyze the epidemiological characteristics and trends of other infectious diarrhea among children under 18 years old in Guangzhou City from 2014 to 2020, and to explore the correlation between climatic factors and the incidence of the disease, so as to provide reference for the early prevention of infectious diseases. Methods: The data of cases of other infectious diarrhea and meteorological data of children under 18 years old in Guangzhou City from 2014 to 2020 were collected through the Chinese Infectious Disease Reporting System and the Guangzhou Meteorological Bureau. The correlation between meteorological factors and the incidence of other infectious diarrhea was analyzed using negative binomial regression. Results: A total of 104 566 cases of other infectious diarrhea among children under 18 years old were reported in Guangzhou City from 2014 to 2020, with a male to female ratio of 1.48∶1. The incidence rate was the highest in 2017 (980.83 per 100 000) and the lowest in 2020 (388.22 per 100 000). The peak of incidence occurred from October to March of the following year. Children under 5 years old accounted for 87.95% of all cases. The number of cases of other infectious diarrhea was negatively correlated with the temperature of the previous 6 days ( IRR = -0.07 ), and positively correlated with the temperature difference on the day of onset ( IRR =0.02) (both P <0.05). It was also positively correlated with the wind speed of the previous 7 days ( IRR=0.07, P <0.05), but there was no statistically significant correlation with the relative humidity on the day of onset ( IRR=-0.00, P >0.05). Conclusions Low temperature, large temperature difference, and high wind speed can increase the risk of other infectious diarrhea. It is necessary to strengthen the prediction and early warning in conjunction with meteorological changes, and warn kindergartens and schools to enhance preventive measures against the clustering of other infectious diarrhea cases.

Cancer is a prevalent and challenging disease that is difficult to treat.Western medicine recognizes the disruption of the immune and inflammatory microenvironment as a crucial factor in the development and progression of cancer.According to traditional Chinese medicine,cancer falls into the categories of"accumulation"and"abnormal masses".Based on the attributes of cold and heat in the overall and local conditions as well as the characteristic of the struggle between the vital qi and pathogenic factors at different stages of this disease,this article proposes the concept of"body coldness and tumor heat"to describe the pathogenesis of cancer formation and progression.This pathogenesis aligns with the disruption of the immune and inflammatory microenvironment in modern medical oncology.The article suggests a treatment approach that focuses on balancing cold and heat,nourishing and protecting yang qi,warming the kidneys,and strengthening the spleen to address the"coldness of the entire body".This approach also involves promoting qi circulation,eliminating dampness,phlegm,and stasis,and detoxifying and dispersing nodules to address the"heat in the tumor locally".By addressing deficiencies,eliminating pathogenic factors,and promoting circulation to alleviate stagnation,the aim is to restore the balance of yin and yang and improve the complex state of"coldness of the entire body"and"heat in the tumor locally".These interventions can ameliorate the disorder in the microenvironment and enhance clinical efficacy.

Objective To investigate the expression of long non-coding RNA(LncRNA)PICSAR in ovarian canc-er,and explore the effects of LncRNA PICSAR on the proliferation,migration,invasion and apoptosis of ovarian cancer cells as well as its possible mechanism of action.Methods The expression levels of LncRNA PICSAR in o-varian cancer tissue and cell line A2780,OVCAR-3,HO-8910 and normal ovarian tissue and cell line IOSE386 were detected by fluorescence quantitative PCR.Ovarian cancer cell lines with the highest expression of LncRNA PICSAR were divided into control group and experimental group,and transfected with negative control small inter-fering RNA(siRNA-NC)or PICSAR knockout small interfering RNA(siRNA-PICSAR)by liposome transfection technique,respectively.The effects of LncRNA PICSAR knockdown on the invasion,migration,proliferation and apoptosis of ovarian cancer cells were analyzed by cell counting assay(CCK-8),clonogenic assay,scratch assay,transwell assay and flow cytometry and so on.The expression levels of autophagy related proteins and apoptosis-re-lated proteins in each group were determined by Western blot.Ovarian cancer cells were treated with rapamycin and hydroxychloroquine as autophagy activator and inhibitor,and Western blot assay was used to detect apoptosis.Results The expression level of LncRNA PICSAR in ovarian cancer tissues was higher than that in normal ovarian tissues.Compared with IOSE386 cell line,LncRNA PICSAR expression levels in ovarian cancer cell lines HO-8910,OVCAR-3 and A2780 increased.Compared with the si-NC group,the proliferation,invasion and migration ability of ovarian cancer cells in si-PICSAR group decreased,and the apoptosis rate increased.The autophagy level of ovarian cancer cells in si-PICSAR group was lower than that in si-NC group.After transfection with siRNA-PIC-SAR,rapamycin activated autophagy to reduce apoptosis,while hydroxychloroquine inhibited autophagy to promote apoptosis.Conclusion LncRNA PICSAR is highly expressed in ovarian cancer tissues and cell lines,and the ma-lignant biological behavior of ovarian cancer cells can be inhibited by knockout of LncRNA PICSAR.The knock-down of LncRNA PICSAR may promote the apoptosis of ovarian cancer cells by regulating autophagy.

Human genetic resources are an indispensable part of national natural science and technology resources,as well as an important strategic resource for safeguarding national security,public health,and social public interests.To promote the effective protection and rational utilization of human genetic resources,as well as improve and optimize the local human genetic resources management system in China,this paper summarized the current situation of administrative approval and supervision of national human genetic resources from 2004 to 2021 by sorting out the national human genetic resources management policies and regulations.Furthermore,the current situation and progress of local human genetic resources management in China were understood from three aspects,including development planning and programs of human genetic resources,administrative licensing and penalties,and the construction of management expert committees.The main problems of local human genetic resources management in China were discussed and analyzed,such as unclear supervision,difficulty in supervision and inspection,and capacity for services.Based on the causes of the problems and the local management work,specific countermeasures and suggestions were put forward from the perspective of clarifying the regulatory policies and procedures for human genetic resources,improving the supervision and inspection mechanisms,and improving the management and service capabilities.

Background::China is one of the countries with the largest burden of gastrointestinal and liver diseases (GILD) in the world. The GILD constitutes various causes of mortality and disability. The study aimed to investigate the trend of GILD in China using the Global Burden of Diseases Study 2019 (GBD 2019) data resources from 1990 to 2019.Methods::The data on the age-standardized mortality rates (ASMR) and disability-adjusted life years (DALYs) for GILD in China from 1990 to 2019 were collected from the GBD 2019 data resources. Furthermore, the ranking of the main causes of deaths and DALYs, as well as the trends of ASMR, DALYs, years of life lost (YLLs), and years of life lost due to disability (YLDs) per 1,000,000 in GILD were reported.Results::The ASMR and DALYs for stomach cancer, liver cancer, and esophageal cancer, which ranked top three among the GILDs from 1990 to 2019, were gradually decreasing. Significant decreases in the ASMR and DALYs were found in diarrheal diseases and acute hepatitis (A, E, and C). However, noteworthy increases were found in those of colon and rectum cancer (CRC) and pancreatic cancer. Trend of DALYs, mortality, and YLLs rates for most of GILD were decreasing from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trend. The DALYs, mortality and YLLs of most GILD diseases showed decreasing trends from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trends.Conclusions::The result of the GBD 2019 showed that the rates of most GILDs decreased in China; however, gastrointestinal and liver cancer, such as stomach cancer still held the top ranking. Furthermore, the shift from infectious diseases to non-communicable causes among GILD burden is occurring.

Marine microorganisms, especially marine fungi, have historically proven their value as a prolific source for structurally novel and pharmacologically active secondary metabolites (Deshmukh et al., 2018; Carroll et al., 2022). The corals constitute a dominant part of reefs with the highest biodiversity, and harbor highly diverse and abundant microbial symbionts in their tissue, skeleton, and mucus layer, with species-specific core members that are spatially partitioned across coral microhabitats (Wang WQ et al., 2022). The coral-associated fungi were very recently found to be vital producers of structurally diverse compounds, terpenes, alkaloids, peptides, aromatics, lactones, and steroids. They demonstrate a wide range of bioactivity such as anticancer, antimicrobial, and antifouling activity (Chen et al., 2022). The genetically powerful genus Emericella (Ascomycota), which has marine and terrestrial sources, includes over 30 species and is distributed worldwide. It is considered a rich source of diverse secondary metabolites with antimicrobial activity or cytotoxicity (Alburae et al., 2020). Notably, Emericella nidulans, the sexual state of a classic biosynthetic strain Aspergillus nidulans, was recently reported as an important source of highly methylated polyketides (Li et al., 2019) and isoindolone-containing meroterpenoids (Zhou et al., 2016) with unusual skeletons.

Objective:Exploring the clinical efficacy of using ultra-thin lobulated anterolateral thigh perforator flap(ALTPF) with retrograde separation of perforating vessels from the superficial and deep junction layer of the superficial fascia to repair large soft tissue defects in the foot.Methods:From August 2021 to November 2022, 8 patients (5 males and 3 females) were admitted to the Second Department of Hand and Foot Surgery, the Affiliated Central Hospital of Dalian University of Technology. The patients were 28 to 52 years old in age. The soft tissue defects were located in dorsal and plantar foot. At the plantar foot, the wound involved the weight-bearing area with explosion of bone, tendon or internal fixtures. The area of soft tissue defects was 6.0 cm × 5.0 cm - 16.0 cm × 8.0 cm, and the sizes of ALTPF were 8.0 cm ×5.5 cm - 18.0 cm × 8.5 cm. Preoperative high frequency CUD combined with CTA angiography were employed to locate the 2 flap perforator vessels. By keeping the perforator vessels at center and according to the soft tissue defect area and the wound shape, an ALTPF with a proper size and shape was designed in anterolateral thigh. The perforator were separated in the boundary layer between superficial and deep fascia, where it helped to obviously thin the flap. After the flap was harvested, it was further lobulated between the 2 perforators into 2 lobes after having confirmed the effective blood supply. Finally the lobulated ALTPF was transferred to covered the defect in foot. Cautions should be taken to ensure that the flap covered the weight-bearing area of foot. All the donor sites were directly sutured. Postoperative follow-up was conducted to observe the survival of flaps and the functional recovery of the reconstructed site, also to evaluate the clinical effect. Postoperative follow-up included outpatient visits and reviews over WeChat or telephone. Recovery of the ankle motor function was evaluated according to the American Orthopedic Foot and Ankle Societ (AOFAS) ankle-hind foot score scale.Results:All 8 ALTPF survived. Over 6 to 18 months (10.8 months in average) of follow-up, the transferred flaps had good blood supply, soft in texture, with good elasticity and thin in appearance. Appearance and function of donor sites recovered well, except 1 patient who had mild scar hyperplasia. The plantar flap had good abrasion resistance. No flap damage, bleeding or granulation tissue hyperplasia occurred when walking. The mean score of AOFAS ankle-hind foot score achieved 95.6.Conclusion:The application of ultra-thin lobulated ALTPF with retrograde separation of perforating vessels from the superficial fascia at the junction layer for repairing large soft tissue defects in the foot has good clinical efficacy.
