Objective: To investigate the trends in mortality and life loss of gastric cancer in Wenzhou City, Zhejiang Province from 2014 to 2023, so as to provide the evidence for formulating the prevention and control strategy for gastric cancer. Methods: The surveillance on causes of death data of permanent residents in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management Information System from 2014 to 2023. The crude mortality of gastric cancer was calculated, and standardized by the data from the Sixth Chinese National Population Census in 2010. The life loss were measured using potential years of life lost (PYLL) and rate of potential years of life lost (PYLLR). The characteristics of mortality and life loss of gastric cancer in different genders and age groups were described. The trends in mortality and PYLLR of gastric cancer were analyzed using the average annual percent change (AAPC). Results: Totally 17 080 deaths were reported due to gastric cancer in Wenzhou City from 2014 to 2023, accounting for 12.58% and ranking third in the order of malignant tumor deaths. The crude mortality of gastric cancer was 20.73/105, and the standardized mortality was 15.22/105, showing decreasing trends (AAPC=-3.311%, -6.470%, both P<0.05). The crude mortality of gastric cancer was 29.22/105 in men and 11.61/105 in women, with standardized mortality rates of 20.81/105 and 8.74/105 (both P<0.05). The crude mortality of gastric cancer appeared a tendency towards a rise with increasing age (P<0.05), reaching the highest rate of 225.88/105 in the group aged 80 to <85 years. The PYLL and PYLLR of gastric cancer were 107 607.50 person-years and 1.37‰. The PYLLR appeared a tendency towards a decline from 2014 to 2023, with AAPC of -6.667% (P<0.05). Conclusions The mortality and PYLLR of gastric cancer in Wenzhou City appeared a tendency towards a decline from 2014 to 2023. Men and the elderly populations were the key groups for the prevention and treatment of gastric cancer.

Methods An analysis was conducted on the discovery and investigation results of six cases of vaccine-derived poliovirus (VDPV) detected in Guangzhou. Results A total of 6 VDPV incidents were reported in Guangzhou from 2011 to June 2024, among which 5 incidents were from sewage sample testing in the Liede Sewage Treatment Plant in Guangzhou, all of which were confirmed as VDPV, with 1 for type I, 1 for type II, and 3 for type III. In addition, one confirmed HFMD case was identified as a type VDPV II carrier. No presence of any wild poliovirus (WPV), VDPV cases, or circulating VDPV (cVDPV) was reported. Conclusion Guangzhou City has maintained a high level of vigilance and effectiveness in the monitoring and prevention of polio. Continuously strengthening the construction of the polio monitoring network, optimizing vaccination strategies, and comprehensively improving public health awareness are still the focus of the prevention and control work in the future.

Objective: To investigate the trends in mortality and life loss due to falls among the elderly in Wenzhou City, Zhejiang Province, so as to provide the basis for formulating prevention and control measures for falls among the elderly. Methods: The data on fall-related deaths among the elderly aged 60 and above in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management Information System from 2015 to 2023. The crude mortality was calculated and standardized using the data from the Sixth National Population Census in 2010. The life loss were measured using potential years of life lost (PYLL), average years of life lost (AYLL), and potential years of life lost rate (PYLLR). The trends in mortality and life loss among the elderly were analyzed using the annual percent change (APC) and average annual percent change (AAPC). Results: There were 11 378 deaths due to falls among the elderly in Wenzhou City from 2015 to 2023, with a crude mortality of 82.67/100 000 and a standardized mortality of 65.32/105, which appeared no significant changing trend (AAPC=3.401%、2.995%,both P>0.05). There was a tendency towards a rise from 2019 to 2023 (APC=12.592%、11.507%, both P<0.05). The majority of falls occurred at home, with 6 312 cases accounting for 55.48%. The primary types of fall-related deaths were slips, trips, and falls on the same level, with 8 541 cases representing 75.07%. The crude mortality and standardized mortality of falls in males were 76.63/105 and 60.86/105, which were lower than that in females at 88.72/100 000 and 70.33/100 000 (both P<0.05), and the trends were consistent with the overall population. The crude mortality of falls among the elderly increased with age (P<0.05). From 2015 to 2023, the crude mortality of falls among the elderly aged 60 to <65 years showed an upward trend (AAPC=4.860%, P<0.05), while no significant trend was observed in other age groups (all P>0.05). The PYLL was 5 123 person-years, the AYLL was 0.45 years per person, and the PYLLR was 0.37‰. From 2015 to 2023, PYLL showed an upward trend (AAPC=5.477%, P<0.05). The PYLL, AYLL, and PYLLR for males were 3.08 times, 3.48 times, and 2.67 times those of females, respectively. Conclusions From 2015 to 2023, the mortality of falls among the elderly in Wenzhou City had remained relatively stable. However, PYLL showed an upward trend. Males and older seniors were key groups for falls prevention. It is recommended to enhance health education and promote age-friendly home modifications to prevent falls among the elderly.

Objective: To investigate the association between overweight, obesity, central obesity and hypertension, so as to provide the basis for formulating targeted hypertension prevention and control strategies. Methods: Permanent residents aged ≥18 years were selected in Wenzhou City, Zhejiang Province from June 2023 to August 2024 by a multistage cluster random sampling method. Data on demographic information, lifestyle, height, weight, waist circumference (WC), blood pressure, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. The prevalence of hypertension was calculated and standardized using the data of the Sixth National Population Census in 2010. Body mass index (BMI) was calculated to determine overweight and obesity, while WC was used to identify central obesity. The association between overweight, obesity, central obesity and hypertension were analyzed using multivariable logistic regression models. Results: A total of 38 593 residents were surveyed, including 19 481 (50.48%) males and 19 112 (49.52%) females. The median age was 46.00 (interquartile range, 26.00) years. The rates of overweight, obesity, and central obesity were 32.74% (12 634 individuals), 10.27% (3 963 individuals), and 27.87% (10 755 individuals), respectively. There were 11 813 cases of hypertension, with a prevalence and standardized prevalence of 30.61% and 24.41%, respectively. Multivariable logistic regression analysis showed that after adjusting for demographic information, lifestyle, diabetes and dyslipidemia, the likelihood of hypertension in the overweight and obesity groups was 1.927 (95%CI: 1.815-2.045) times and 3.724 (95%CI: 3.404-4.073) times that of the normal BMI group, respectively. The likelihood of hypertension in the central obesity group was 2.346 (95%CI: 2.214-2.486) times that of the normal WC group. The likelihood of hypertension in the central obesity only, overweight only, overweight with central obesity, obesity only and obesity with central obesity groups was 1.586 (95%CI: 1.391-1.809), 1.704 (95%CI: 1.582-1.835), 2.433 (95%CI: 2.254-2.626), 1.768 (95%CI: 1.424-2.194), and 4.466 (95%CI: 4.053-4.921) times that of the normal BMI and WC group, respectively. Conclusions Overweight, obesity and central obesity were all associated with hypertension among adult residents. The highest likelihood of hypertension was observed among adult residents with both general obesity and central obesity.

BACKGROUND:Neuropilin 1 plays a critical role in fracture healing,especially in osteogenesis-angiogenesis coupling. Osteogenesis-coupled angiogenesis is vital for fracture healing,including angiogenesis and bone formation (especially H-type vessel formation) and their association. OBJECTIVE:To review the research progress of neuropilin 1 in promoting osteogenesis-coupled angiogenesis during fracture healing.METHODS:The literature search was performed in the PubMed and Chinese National Knowledge Infrastructure databases for articles published from January 1982 to April 2024 using the search terms "Neuropilin-1,neuropilin 1,NRP1,neuropilin-1,NRP-1,Neuropilin 1,Nrp1,Nrp-1." We identified 43 articles associated with fracture healing,H-type vessels,arteries,bone cells,and angiogenesis-osteogenesis coupling. Moreover,24 articles were searched manually. Finally,67 papers were included.RESULTS AND CONCLUSION:(1) Angiogenesis,osteoblastogenesis,and their association were critical for angiogenesis-osteogenesis coupling during fracture healing.

To explore the differentially expressed genes (DEGs) related to biosynthesis of active ingredients in wolfberry fruits of different varieties of Lycium barbarum L. and reveal the molecular mechanism of the differences of active ingredients, we utilized Illumina NovaSeq 6000 high-throughput sequencing technology to conduct transcriptome sequencing on the fruits of 'Ningqi No.1' and 'Ningqi No.7' during the green fruit stage, color turning stage and maturity stage. Subsequently, we compared the profiles of related gene expression in the fruits of the two varieties at different development stages. The results showed that a total of 811 818 178 clean reads were obtained, resulting in 121.76 Gb of valid data. There were 2 827, 2 552 and 2 311 DEGs obtained during the green fruit stage, color turning stage and maturity stage of 'Ningqi No. 1' and 'Ningqi No. 7', respectively, among which 2 153, 2 050 and 1 825 genes were annotated in six databases, including gene ontology (GO), Kyoto encyclopedia of genes and genomes (KEGG) and clusters of orthologous groups of proteins (KOG). In GO database, 1 307, 865 and 624 DEGs of green fruit stage, color turning stage and maturity stage were found to be enriched in biological processes, cell components and molecular functions, respectively. In the KEGG database, the DEGs at three developmental stages were mainly concentrated in metabolic pathways, biosynthesis of secondary metabolites and plant-pathogen interaction. In KOG database, 1 775, 1 751 and 1 541 DEGs were annotated at three developmental stages, respectively. Searching the annotated genes against the PubMed database revealed 18, 26 and 24 DEGs related to the synthesis of active ingredients were mined at the green fruit stage, color turning stage and maturity stage, respectively. These genes are involved in carotenoid, flavonoid, terpenoid, alkaloid, vitamin metabolic pathways, etc. Seven DEGs were verified by RT-qPCR, which showed consistent results with transcriptome sequencing. This study provides preliminary evidences for the differences in the content of active ingredients in different Lycium barbarum L. varieties from the transcriptional level. These evidences may facilitate further exploring the key genes for active ingredients biosynthesis in Lycium barbarum L. and analyzing their expression regulation mechanism.

ObjectiveTo explore the mechanism of Gancao Fuzitang （GCFZ）in inhibiting the bone destruction of collagen-induced arthritis （CIA） model in mice. MethodThirty male DBa/1J mice were randomly divided into normal group， CIA group， low-dose GCFZ group （GCFZ-L， 2.4 g·kg^-1）， high-dose GCFZ group （GCFZ-H， 4.8 g·kg^-1）， and methotrexate group （MTX， 1 mg·kg^-1）， with six mice in each group. The CIA model was induced by secondary immunization method. The arthritis index of mice in each group was observed and recorded， and the histopathological changes in ankle joint were observed by hematoxylin-eosin （HE） staining. The damage to ankle cartilage was detected by safranin O-fast green staining. Micro-CT scanning was used to detect the bone destruction of ankle joint， and the expression of nuclear factor-κB p65 （NF-κB p65）， p-NF-κB p65， inhibitory-κB kinase α/β （IKKα/β）， and p-IKKα/β was observed by immunohistochemical staining. ResultCompared with the normal group， the CIA group showed manifest joint swelling and increased arthritis index score （P<0.01）. Compared with the CIA group， the groups with drug intervention could inhibit joint swelling and reduce arthritis index score （P<0.05， P<0.01）. As revealed by HE staining and safranine O-green staining， compared with the CIA group， the groups with drug intervention could inhibit synovial invasion and reduce the destruction of articular cartilage. Micro-CT scanning analysis showed that compared with the CIA group， the GCFZ-H group and the MTX group showed reduced bone destruction scores （P<0.01）. The immunohistochemical results showed that compared with the normal group， the CIA group showed increased optical density values of NF-κB p65， p-NF-κB p65， IKKα/β， and p-IKKα/β（P<0.01）. Compared with the CIA group， the GCFZ-H group and the MTX group showed reduced optical density values of NF-κB p65， p-NF-κB p65， IKKα/β， and p-IKKα/β（P<0.05，P<0.01）. In the GCFZ-L group， only the NF-κB p65 optical density value decreased（P<0.01）. ConclusionGCFZ may inhibit bone destruction in CIA mice by regulating the NF-κB signaling pathway.
