ABSTRACT
Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.
ABSTRACT
Objective:To explore the value of 5G robotic remote ultrasound in the diagnosis of plateau pulmonary edema(HAPE).Methods:A total of 27 patients who quickly entered Nagqu, Tibet at an altitude of 4 600 m-5 600 m from March to December 2021 and developed one of the clinical symptoms of HAPE were collected. All patients were examined by 5G remote robotic ultrasound and lung CT respectively. Kappa test was used to analyze the consistency of the two diagnostic results, and McNemar test was used to compare the difference in diagnostic results. The ROC curve was used to analyze the sensitivity and specificity of remote lung ultrasound scores in the diagnosis of HAPE.Results:Among the 27 patients, 16 showed thickening of pleural line, increasing of B line, lung consolidation, pleural effusion, etc. Meanwhile, 11 showed no abnormality. Additionally, 8 cases had diffuse pulmonary fluid in both lungs, and 8 cases had localized pulmonary fluid. ROC curve showed that the area under the curve of lung ultrasound score for the diagnosis of HAPE was 0.947 (95% CI=0.78-0.99, P<0.001). The sensitivity and specificity were 0.933 and 0.917, respectively. Lung CT diagnosis was positive in 15 cases. Lung CT showed thickening of lung texture, ground glass, small nodular shadow, fine reticulate shadow, etc. The diagnostic results of the two techniques were in good agreement (Kappa=0.924, P<0.001), and there was no significant difference between the two methods ( P>0.05). Conclusions:5G remote robotic ultrasound has high consistency with CT in the diagnosis of HAPE and is an alternative early diagnosis method for HAPE. It may have clinical application value in scattered medical resources and remote plateau areas.
ABSTRACT
The mechanism underlying the occurrence and development of gastric cancer is complex. Abnormal activation of cell signaling pathways play a vital role in the occurrence and development of cancer. The Wnt/β-catenin signaling pathway participates in gastric cancer cell proliferation, invasion and metastasis and effectively induces drug resistance of the gastric cancer cells; it is also the key signal to mediate gastric carcinogenesis. Disturbances of Wnt/β-catenin signaling pathway can inhibit the growth, invasion and metastasis of gastric cancer and increase the sensitivity of the cancer cells to chemotherapeutic drugs. The authors reviewed the research progress of the role of Wnt/β-catenin signaling pathway in the occurrence and development of gastric cancer and discussed the prospective of preventing gastric cancer by interfering with Wnt/β-catenin signaling pathway.

ABSTRACT
Objective To know the quality of iodized salt and the current situation of the salt coverage in Tibet,and to provide scientific basis for proposing proper prevention and control measures to Iodine dificiency disorders(IDD). Methods In 2008, according to the "Sampling Methods of the Main Products in the Salt Industry",one batch fifteen salt samples were collected in iodized salt processing factory in Tibet. Five townships were chosen in each county based on 5 different directions of east, south, west, north and center. If the monitoring county has less than five townships, then all of the townships were sampled. In each township, four villages were selected withrandom sampling and importance sampling. In each township, 15 households were selected for salt collection. Results A batch of 15 salt samples in a salt processing plant were tested, and all of them were qualified with salt iodine(34.6±1.58) mg/kg. A total of 21 107 edible salt samples were tested, and 11 203 of them were qualified iodized salt. These results meant that the provincial iodized salt coverage rate was 53.08%. Shannan iodized salt coverage rate was 94.31% (3395/3600) which was the highest in Tibet. Those of Nagqu, Changdu, Ngari were lower, they were 29.84% (897/3006), 24.94% (823/3300) and 17.08% (205/1200), respectively. Conclusions The quality of iodized salt in Tibet is up to the national standard, but the coverage rate of iodized salt is very low.We suggest that the strategy should be carried out according to the national overall program strategy and supplement iodized oil capsule for special groups.
ABSTRACT
Objective To investigate the impact of high altitude on human gastric mucosa and its underlying mechanisms. Methods Twenty-five native Tibetans with chronic mountain sickness CMS residing at high altitude (4500 m) were examined for ultrastrueture and pathological changes of gastric mucosa. The other 25 native Tibetans residing at low altitude (＜2000 m) were served as control.The expression of hypoxia-inducible factor (HIF)-1α in human gastric mucosa was detected with immunohistochemistry. Results The color of gastric mucosa presented dark in patients with CMS.The histopathological examination showed significant differecnce in incidence of cnronc body gastritis and atrophic gastritis between CMS group and control group (P＜0. 05). The transmission electronic microscopy revealed that the epithlieal cells of gastric mucosa were impared in CMS group compared to control group. The expression of HIF-1α protein was increased in CMS group in comparison of control group (102.94± 34.04 vs 14.04 ± 6.53, P＜0.05). Conclusions The high altitude may involve in damage of gastric mucosa and the up-regulation of HIF-1α protein may involve in its mechanism.
