Hypoxia results from long-term anti-angiogenic therapy and can stimulate hypoxia-inducible factors (HIFs). HIF-induced hy-poxia signaling is involved in various steps in tumor invasive-metastatic cascade. On the one hand, HIFs regulate epithelial-mesenchy-mal transition. On the other hand, the characteristics of pericytes around vessels and the links among endothelial cells can change;thus, tumor cells can more easily intravasate into blood vessels, survive in peripheral blood, and then reach specific organs, ultimately resulting in metastasis. This review discusses the emerging mechanisms of long-term anti-angiogenic therapy and the occurrence of metastasis.

Objective: To investigate the awareness of adolescent sexual knowledge among primary school students in Hangzhou City, so as to provide insights into adolescent sex education. Methods: In May 2021, grades 5 and 6 students were sampled from 5 primary schools in urban areas and 5 primary schools in suburban areas of Hangzhou City. The demographic features, awareness of adolescent sexual knowledge and sources of acquiring adolescent sexual knowledge were investigated using electronic questionnaires, and the awareness of adolescent sexual knowledge were analyzed among primary school students. Results: Totally 1 812 students completed valid questionnaires, including 861 grade 5 students ( 47.52% ) and 951 grade 6 students ( 52.48% ), 936 boys ( 53.86% ) and 836 girls (46.14%), and 912 students living in urban areas (50.33%) and 900 students living in suburban areas ( 49.67% ). The awareness rates of adolescent physiological knowledge, adolescent health knowledge, private parts and sexual harassment behaviors were 53.20%, 46.30%, 60.49% and 92.55%, respectively, and the awareness rates of adolescent physiological knowledge ( 69.52% vs. 39.14%; χ2=168.001), adolescent health knowledge (55.74% vs. 38.22%; χ2=55.619 ), private parts ( 72.49% vs. 50.20%; χ2=93.550 ) and sexual harassment behaviors ( 96.05% vs. 89.55%; χ2=27.621 ) were significantly higher in girls than in boys ( all P<0.05 ). The awareness rates of adolescent physiological knowledge ( 63.72% vs. 41.58%; χ2=88.989 ), private parts ( 64.56% vs. 55.98%; χ2=13.926 ) and sexual harassment behaviors ( 93.80% vs. 91.17%; χ2=4.509 ) were significantly greater among grade 6 students than among grade 5 students ( all P<0.05 ), and the awareness rates of adolescent physiological knowledge ( 69.96% vs. 36.22%; χ2=207.041 ), adolescent health knowledge (58.99% vs. 33.44%; χ2=118.903 ) and sexual harassment behaviors ( 96.16% vs. 88.89%; χ2=34.754 ) were significantly higher among students living in urban areas than among students living in suburban areas ( all P<0.05 ). Primary school students mainly acquired sexual knowledge from their parents ( 1 208 students, 66.67% ) and teachers ( 1 161 students, 64.07%), and the source of life was the predominant demand for sexual knowledge ( 969 students, 53.48% ). Conclusions The awareness of adolescent sexual knowledge remains to be increased among grade 5 and 6 primary school students in Hangzhou City. More attention paid to male students and students living in suburban areas, and building a school-family-community educational network are recommended to increase the awareness of adolescent sexual knowledge among primary school students.

Objective To investigate the clinical efficacy of auricular plaster therapy for depression in newly diagnosed type 2 diabetes.Methods Sixty patients with depression in newly diagnosed type 2 diabetes were randomly allocated to group A of 18 cases, broup B of 22 cases and group C of 20cases. In addition to conventional hypoglycemic treatment, group A received psychological intervention; group B, auricular plaster therapy; group C, oral administration of fluoxetine hydrochloride capsules. Pre-/post-treatment changes in fasting blood glucose, two-hour postprandial blood glucose, glycosylated hemoglobin and the Hamilton Depression Scale (HAMD) score were observed in the three groups after eight weeks of treatment. The clinical therapeutic effects were compared between the three groups.Results There were no statistically significant post-treatment differences in fasting blood glucose, two-hour postprandial blood glucose and glycosylated hemoglobin among the three groups (P>0.05). There was a statistically significant pre-/post-treatment difference in the HAMD score in the three groups (P<0.05). There was a statistically significant difference in the HAMD score between groups B and A at two, four, six and eight weeks after treatment (P<0.05), between groups B and C at two weeks after treatment (P<0.05) and between groups C and A at two, six and eight weeks after treatment (P<0.05). The total efficacy rate was 77.8% in group A, 90.9% in group B and 90.0% in the control group. There was a statistically significant difference in the total efficacy rate between group B or C and group A (P<0.05).Conclusion Auricular plaster therapy plus medication is an effective way to treat depression in newly diagnosed type 2 diabetes.

The LEAFY (LFY) homologous gene of Dendrobium moniliforme (L.) Sw. was cloned by new primers which were designed based on the conservative region of known sequences of orchid LEAFY gene. Partial LFY homologous gene was cloned by common PCR, then we got the complete LFY homologous gene Den LFY by Tail-PCR. The complete sequence of DenLFY gene was 3 575 bp which contained three exons and two introns. Using BLAST method, comparison analysis among the exon of LFY homologous gene indicted that the DenLFY gene had high identity with orchids LFY homologous, including the related fragment of PhalLFY (84%) in Phalaenopsis hybrid cultivar, LFY homologous gene in Oncidium (90%) and in other orchid (over 80%). Using MP analysis, Dendrobium is found to be the sister to Oncidium and Phalaenopsis. Homologous analysis demonstrated that the C-terminal amino acids were highly conserved. When the exons and introns were separately considered, exons and the sequence of amino acid were good markers for the function research of DenLFY gene. The second intron can be used in authentication research of Dendrobium based on the length polymorphism between Dendrobium moniliforme and Dendrobium officinale.

Objective: To identify the spatio-temporal clustering analysis of mumps in Wenzhou City, Zhejiang Province from 2010 to 2023, so as to provide the basis for improving mumps prevention and control strategies. Methods: Data of mumps cases in Wenzhou City from 2010 to 2023 were collected from the Monitoring and Reporting Management System of Chinese Disease Prevention and Control Information System. The spatio-temporal clustering characteristics of mumps incidence were identified using spatial autocorrelation analysis and spatio-temporal scan analysis. Results: A total of 20 455 mumps cases were reported in Wenzhou City from 2010 to 2023, with an average annual incidence of 17.54/105. There were 12 919 male and 7 536 female cases, with a male-to-female ratio of 1.71∶1. The children aged 5-<10 years had the highest incidence of mumps at 135.29/105. The incidence of mumps showed a downward trend from 46.82/105 in 2010 to 3.59/105 in 2023 (P<0.05). The incidence of mumps peaked from May to July and from November to January during 2010 and 2012, the winter peak became less evident after 2013, and no seasonal trends were observed after 2020. Spatial autocorrelation analysis showed there was a positive spatial correlation of mumps of other years, with the exception of 2018 (all Moran's I >0, all P<0.05). Lucheng District, Longwan District, Ouhai District, Cangnan County and Rui'an City were high-high clustering sites. Spatio-temporal scan analysis showed that the primary clustering area was centered in Nanbaixiang Street, Ouhai District, covering 50 towns (streets), with the clustering time from April 2010 to August 2013; the secondary clustering area was centered in Zaoxi Town, Cangnan County, covering 24 towns (streets), with the clustering time from January 2010 to June 2013. Conclusions The incidence of mumps in Wenzhou City from 2010 to 2023 showed a downward trend. The urban areas, Cangnan County and Rui'an City were the clustering areas.
