Ji X, He G, Wang K, Zhang Y, Yin J, Wang K

J Public Health (Oxf), 2023 Mar 14;45(1):40-46.
PMID: 35137200 DOI: 10.1093/pubmed/fdab410

BACKGROUND: Helicobacter pylori causes large burden of gastric cancer (GC) in Asia. We aimed to comprehensively quantify the burden of GC attributable to H. pylori infection in Asia.
METHODS: We searched related articles from January 1998 to December 2020 to obtain the prevalence and relative risks (or odds ratio) of GC associated with H. pylori in Asia. The burden of GC attributable to H. pylori infection was quantified by Population Attributable Fraction (PAF) and Disability-adjusted life-years (DALYs).
RESULTS: We quantified the burden of GC attributable to H. pylori infection with 415.6 thousand DALYs and 38.03% PAF through the five included Asian countries in 2019. The study found that the burden had obvious regional differences. The DALYs ranged from 298.9 thousand in China to 1.9 thousand in Malaysia, and the PAFs were between 58.00% in Japan and 30.89% in China. The average prevalence of H. pylori in the included general population was estimated to be 56.29%.
CONCLUSIONS: Helicobacter pylori poses a huge disease burden of GC to the population, and its eradication should receive attention, especially in the countries with high incidence of and mortality due to GC.

Liu J, He G, Zhang H, Yahya MM

Gland Surg, 2023 Sep 25;12(9):1318-1325.
PMID: 37842525 DOI: 10.21037/gs-23-5

BACKGROUND: Breast preservation can considerably improve the postoperative living quality of breast cancer patients. Through this study, we proposed a novel, safe, and effective surgical modality for breast preservation in patients with early breast cancer.
CASE DESCRIPTION: Herein, we present a case report of a patient with early-stage breast cancer (T1cN0M0), who underwent skin-sparing nipple areola hypodermic gland resection combined with primary breast reconstruction using silicone implants. The patient was administered with general anesthesia, and the implants were inserted using a insufflation-free suspension and hook suspension under the pectoralis major muscle. The patient was followed up on postoperative days 1, 2, 7, 14, 30, 60, and 100 to check for any complications, such as upper limb edema, paresthesia, or flap necrosis. The patient experienced no complications. No obvious surgical scars or axillary surface infections were observed. The patient was satisfied with the surgical outcome, and this treatment approach reduced her treatment costs by approximately USD 2,600.
CONCLUSIONS: The new surgical procedure for breast reconstruction considerably improved the quality of life of the patient; no postoperative complications such as skin flap necrosis, paresthesia, or upper limb edema were experienced by the patient; and the treatment costs were reduced. In addition, this method effectively overcomes the concerns related to axillary space instability and limited operative space, rendering it worthy of promotion in clinical practice.

Within last 17 years two widespread epidemics of severe acute respiratory syndrome (SARS) occurred in China, which were caused by related coronaviruses (CoVs): SARS-CoV and SARS-CoV-2. Although the origin(s) of these viruses are still unknown and their occurrences in nature are mysterious, some general patterns of their pathogenesis and epidemics are noticeable. Both viruses utilize the same receptor-angiotensin-converting enzyme 2 (ACE2)-for invading human bodies. Both epidemics occurred in cold dry winter seasons celebrated with major holidays, and started in regions where dietary consumption of wildlife is a fashion. Thus, if bats were the natural hosts of SARS-CoVs, cold temperature and low humidity in these times might provide conducive environmental conditions for prolonged viral survival in these regions concentrated with bats. The widespread existence of these bat-carried or -released viruses might have an easier time in breaking through human defenses when harsh winter makes human bodies more vulnerable. Once succeeding in making some initial human infections, spreading of the disease was made convenient with increased social gathering and holiday travel. These natural and social factors influenced the general progression and trajectory of the SARS epidemiology. However, some unique factors might also contribute to the origination of SARS in Wuhan. These factors are discussed in different scenarios in order to promote more research for achieving final validation.
Feasibility analysis of treating breast cancer patients with breast-conserving surgery via a periareolar incision combined with non-lipolytic suspension-type mastoscopy

Liu J, He G, Zhang Y, Wong MP, Chu J, Kong L, et al.

Sci Rep, 2023 Jul 26;13(1):12129.
PMID: 37495629 DOI: 10.1038/s41598-023-39199-y

The purpose is to analyze and compare postoperative recovery and complication incidence between a periareolar incision combined with Suspension-type Mastoscopic Axillary Lymph Node Dissection (SMALND) and traditional inflated Mastoscopic Axillary Lymph Node Dissection (MALND). This was a randomized trial conducted from June 1, 2020, to April 30, 2022, in the Department of Second Breast Surgery, Shengjing Hospital of China Medical University, and the Department of Thyroid and Breast Surgery, Zibo Central Hospital, in accordance with the criteria of inclusion and exclusion. Overall, 126 patients diagnosed and treated for early-stage breast cancer were selected to undergo periareolar-incision breast-conserving surgery. Those patients who underwent periareolar-incision surgery combined with SMALND formed the observation group (SMALND Group), while those who underwent periareolar-incision surgery combined with traditional inflation became MALND Group. In the two groups, paired data "t" was used to examine, analyze, and compare the postoperative daily drainage volume and drain removal time, while paired data "χ2" was used to examine, analyze, and compare the incidences of postoperative upper limb edema and paresthesia. There were 64 cases in the SMALND Group and 62 cases in the MALND Group. Between the two clusters, no differences were found in age, clinical staging, BMI, and breast cancer classification (P > 0.05). The intraoperative surgery time of the SMALND Group was 43.37 ± 6.27 min while that of the MALND Group was longer: 45.72 ± 4.25 min (P

The total number of cumulative cases and deaths from the COVID-19 pandemic caused by SARS-CoV-2 is still increasing worldwide. Although many countries have actively implemented vaccination strategies to curb the epidemic, there is no specific efficient therapeutic drug for this virus to effectively reduce deaths. Therefore, the underappreciated macromolecular compounds have become the spotlight of research. Furthermore, the medicinal compounds in plants that provide myriad possibilities to treat human diseases have become of utmost importance. Experience indicates that Traditional Chinese medicine effectively treats SARS and has been used for treating patients with COVID-19 in China. As one of the world's oldest herbal remedies, licorice is used for treating patients with all stages of COVID-19. Glycyrrhizic acid (GA), the main active compound in licorice, has been proven effective in killing the SARS virus. Meanwhile, as a natural plant molecule, GA can also directly target important protein structures of the SARS-CoV-2 virus and inhibit the replication of SARS-CoV-2. In this review, we summarized the immune synergy of GA and its potential role in treating COVID-19 complications. Besides, we reviewed its anti-inflammatory effects on the immune system and its positive effects in cooperation with various drugs to fight against COVID-19 and its comorbidities. The purpose of this review is to elucidate and suggest that GA can be used as a potential drug during COVID-19 treatment.

In recent years, the incidence and mortality of infectious diseases in China are increasing. Infectious diseases, especially new infectious diseases, seriously threaten people's lives. Recent works found that most of the emerging infectious diseases come from wild life. At the same time, the impact of human activities on the environment has further deteriorated the living environment of wildlife. However, with the conducted in-depth research on virus, human beings increase the risk of getting infected. Taking Beta Coronavirus as the example, we analyzed the transmission risks of coronavirus in the prevention and control of the outbreaks of emerging infectious diseases, and recommend the prevention and control strategies before, during and after the viral outbreak. Additional works are urgently needed to better define the biological and epidemiological characteristics of these viruses.

There is an established link between food promotions and children's food purchase and consumption. Children in developing countries may be more vulnerable to food promotions given the relative novelty of advertising in these markets. This study aimed to determine the scope of television food advertising to children across the Asia-Pacific to inform policies to restrict this marketing. Six sites were sampled, including from China, Indonesia, Malaysia and South Korea. At each site, 192 h of television were recorded (4 days, 16 h/day, three channels) from May to October 2012. Advertised foods were categorized as core/healthy, non-core/unhealthy or miscellaneous, and by product type. Twenty-seven percent of advertisements were for food/beverages, and the most frequently advertised product was sugar-sweetened drinks. Rates of non-core food advertising were highest during viewing times most popular with children, when between 3 (South Korea) and 15 (Indonesia) non-core food advertisements were broadcast each hour. Children in the Asia-Pacific are exposed to high volumes of unhealthy food/beverage television advertising. Different policy arrangements for food advertising are likely to contribute to regional variations in advertising patterns. Cities with the lowest advertising rates can be identified as exemplars of good policy practice.
Fulltext Impact of the Inflow Population From Outbreak Areas on the COVID-19 Epidemic in Yunnan Province and the Recommended Control Measures: A Preliminary Study

Sun Z, He G, Huang N, Chen H, Zhang S, Zhao Z, et al.

Front Public Health, 2020;8:609974.
PMID: 33344408 DOI: 10.3389/fpubh.2020.609974

Background: COVID-19 developed into a global pandemic in 2020 and poses challenges regarding the prevention and control capabilities of countries. A large number of inbound travelers from other regions could lead to a renewed outbreak of COVID-19 in the local regions. Globally, as a result of the imbalance in the control of the epidemic, all countries are facing the risk of a renewed COVID-19 outbreak brought about by travelers from epidemic areas. Therefore, studies on a proper management of the inbound travelers are urgent. Methods: We collected a total of 4,733,414 inbound travelers and 174 COVID-19 diagnosed patients in Yunnan province from 21 January 2020 to 20 February 2020. Data on place of origin, travel history, age, and gender, as well as whether they had suspected clinical manifestations for inbound travelers in Yunnan were collected. The impact of inbound travelers on the local epidemic was analyzed with a collinear statistical analysis and the effect of the control measures on the epidemic was evaluated with a sophisticated modeling approach. Results: Of the 174 COVID-19 patients, 60.9% were not from Yunnan, and 76.4% had a history of travel in Hubei. The amount of new daily cases in Yunnan was significant correlated with the number of inbound travelers from Hubei and suspected cases among them. Using Susceptible-Exposed-Infectious-Recovered (SEIR) model analysis, we found that the prevention and control measures dropped the local R0 down to 1.07 in Yunnan province. Conclusions: Our preliminary analysis showed that the proper management of inbound travelers from outbreak areas has a significantly positive effect on the prevention and control of the virus. In the process of resettlement, some effective measures taken by Yunnan province may provide an important reference for preventing the renewed COVID-19 outbreak in other regions.

Extensive clinical efforts have been made to control the severity of dengue diseases; however, the dengue morbidity and mortality have not declined. Dengue virus (DENV) can infect and cause systemic damage in many organs, resulting in organ failure. Here, we present a novel report showing a tailored stem-cell-based therapy that can aid in viral clearance and rescue liver cells from further damage during dengue infection. We administered a combination of hematopoietic stem cells and endothelial progenitor cells in a DENV-infected BALB/c mouse model and found that delivery of this cell cocktail had improved their liver functions, confirmed by hematology, histopathology, and next-generation sequencing. These stem and progenitor cells can differentiate into target cells and repair the damaged tissues. In addition, the regime can regulate endothelial proliferation and permeability, modulate inflammatory reactions, enhance extracellular matrix production and angiogenesis, and secrete an array of growth factors to create an enhanced milieu for cell reparation. No previous study has been published on the treatment of dengue infection using stem cells combination. In conclusion, dengue-induced liver damage was rescued by administration of stem cell therapy, with less apoptosis and improved repair and regeneration in the dengue mouse model.

Seagrass genomes reveal ancient polyploidy and adaptations to the marine environment

Ma X, Vanneste S, Chang J, Ambrosino L, Barry K, Bayer T, et al.

Nat Plants, 2024 Feb;10(2):240-255.
PMID: 38278954 DOI: 10.1038/s41477-023-01608-5

We present chromosome-level genome assemblies from representative species of three independently evolved seagrass lineages: Posidonia oceanica, Cymodocea nodosa, Thalassia testudinum and Zostera marina. We also include a draft genome of Potamogeton acutifolius, belonging to a freshwater sister lineage to Zosteraceae. All seagrass species share an ancient whole-genome triplication, while additional whole-genome duplications were uncovered for C. nodosa, Z. marina and P. acutifolius. Comparative analysis of selected gene families suggests that the transition from submerged-freshwater to submerged-marine environments mainly involved fine-tuning of multiple processes (such as osmoregulation, salinity, light capture, carbon acquisition and temperature) that all had to happen in parallel, probably explaining why adaptation to a marine lifestyle has been exceedingly rare. Major gene losses related to stomata, volatiles, defence and lignification are probably a consequence of the return to the sea rather than the cause of it. These new genomes will accelerate functional studies and solutions, as continuing losses of the 'savannahs of the sea' are of major concern in times of climate change and loss of biodiversity.
