Results: Totally 5 435 deaths occurred due to cancer in Ouhai District from 2013 to 2020, and the crude and standardized mortality rates were 154.10/105 and 119.41/105, respectively. The crude mortality of cancer was higher in men than in women ( 196.26/105 and 111.09/105; χ2=415.623, P<0.001 ). The standardized mortality of cancer among whole populations, the crude mortality in men and the standardized mortality in men showed a tendency towards a reduction ( P<0.05 ), with APC of -3.25%, -2.18% and -4.78%, respectively. The crude mortality of cancer showed an upward trend with age ( χ2trend=9 260.583, P<0.001 ). Lung cancer, liver cancer, stomach cancer, colorectal cancer and esophagus cancer were the five leading causes of cancer-related mortality, which accounted for 66.68% of all cancer mortality. Liver cancer, lung cancer, stomach cancer, colorectal cancer and brain cancer were the five leading causes of life lost, with YPLL of 11 191.50, 8 231.00, 6 000.00, 3 892.00 and 2 693.50 person-years, respectively. Leukemia was the primary cause of AYLL ( 25.17 years per person ). Conclusions Both the standardized mortality and the life lost due to cancer showed a tendency towards a reduction in Ouhai District from 2013 to 2020, and men and the elderly were high-risk populations. Lung cancer, liver cancer, stomach cancer, colorectal cancer, leukemia, brain cancer, and female breast cancer should be listed among cancers in Ouhai District prioritized for control

Objective To compare the safety and efficacy of carotid artery stenting (CAS) and carotid endarterectomy(CEA) for the treatment of carotid stenosis. Methods The electronic databases (PubMed, EMbase, Cochrane Central Register of Controlled Trials, CNKI, VIP and Wanfang) were searched in order to retrieve randomized controlled trials (RCTs) about comparing CAS and CEA for the treatment of carotid stenosis. Cochrane collaboration's RevMan 5.0.24 were used for analyzing data. Results Twelve RCTs totalling 6903 patients (3460 patients were randomized to CAS and 3443 randomized to CEA) with symptomatic or asymptomatic stenosis were included in the meta-analysis. There were significantly higher 30-day relative risks after CAS than after CEA for death or any stroke [RR=1.64, 95%CI (1.33-2.03), P＜0.00001] and for stroke [RR=1.70, 95%CI (1.34-2.14), P＜0.00001]. The relative risks of myocardial infarction [RR=0.62, 95%CI (0.39-0.97), P=0.04] and cranial neuropathy [RR=0.07, 95%CI (0.03-0.16), P＜0.00001] was significantly less after CAS than after CEA. The relative risks of death [RR=1.27, 95%CI (0.82-1.96), P=0.29] or disabling stroke within 30 days [RR=1.33, 95%CI (0.78-2.28), P=0.29] and any stroke or death at 1 year after the procedures [RR=0.96, 95%CI (0.63-1.46), P=0.84] did not differ significantly between CAS and CEA operation. Conclusions CEA remains the first choice for treatment of carotid stenosis for patients with low surgery risk. For patients with high surgery risk and unsuitable for surgery, CAS has more advantages. It is reasonable to view CAS and CEA as complementary rather than competing modes of therapy.

BACKGROUND:The mechanism underlying orthodontic-induced external root resorption is not yet clear, and it differs individual y. Kidney deficiency has been proved to be related to bone diseases which mediated by different cytokines. Interleukin-17 is an important cytokine involved in external root resorption. So figuring out whether kidney deficiency and interleukin-17 are related to root resorption wil be helpful for etiological research.
OBJECTIVE:To explore the relationship between kidney deficiency physique, interleukin-17 and root resorption during orthodontic treatment in rats.
METHODS:Thirty-six Wistar rats were selected and equivalently randomized into two groups, fol owed by modeled into kidney deficiency (kidney deficiency group) or injected with normal saline (control group), respectively. Afterwards, the right maxil ary of each rat served as an orthodontic force model, and the left maxil ary as a non-orthodontic force model. Al rats were respectively sacrificed under general anesthesia at the 3, 7 and 14 days after given orthodontic force. Then, the mesial surface of the root of maxil ary first molars and the expression level of interleukin-17 were observed through hematoxylin-eosin staining and immunohistochemical method.
RESULTS AND CONCLUSION:Histological observation showed that significantly increasing root resorption in a time-dependent manner could be observed, and there were various absorbed lacunae of osteoclasts on the enamel in the kidney deficiency orthodontic force group. The alveolar bone resorption and widened periodontal membrane appeared in the control orthodontic force group. While no remarkable root and alveolar bone resorptions were found in the other two non-orthodontic force groups. The expression level of interleukin-17 in the kidney deficiency orthodontic force group was higher than that in the control orthodontic force group;the expression level of interleukin-17 in the kidney deficiency non-orthodontic force group was higher than that in the control non-orthodontic force group. In conclusion, kidney deficiency patients are easy to develop root resorption, the mechanism of which is maybe relevant to the upregulation of interleukin-17.
