The new era imposes heightened demands on medical professionals,who must not only possess a solid theoretical foundation but also exhibit strong practical skills and innovative capabilities.The quality of medical func-tional laboratory construction is crucial for cultivating high-caliber medical talents.In light of the current developmental status and trends regarding functional experiment teaching within Chinese higher education institutions,particularly the disparities in development across various regions and institutions,the Functional Experiment Teaching Committee of the Chinese Pathophysiology Society has developed an expert consensus on laboratory construction standards.This consensus was established through comprehensive investigations,research,and extensive discussions to provide a reference for di-verse institutions to continuously enhance their levels of laboratory construction.

There are difficulties in the treatment of Alzheimer's disease (AD) in medical community. Since the surgery of cervical deep lymphatic vessel/lymphatic node-vein anastomosis (LVA/LnVA) has made clinical improvement in patients with AD, it offers a surgical option to treat AD. Especially improvements in cognitive impairment. However the mechanism in treatment of AD is not yet made clear. This article preliminarily explores the mechanism in improvement of some symptoms in patients with AD through cervical deep LVA/LnVA on the basis of morphological characteristics of the cribriform plate-cervical lymphatic pathway.

Objective To collect and summarize the opinions of experts on the improvement of China's disease prevention and control system published in the public media, so as to provide reference for the relevant construction planning of the government. Methods: Articles were collected from January to May, 2020, which were published on Chinese mainstream media. Based on the analysis of literature and the basic characteristics of experts, Analytic hierarchy process (AHP) was used to summarize the construction points of experts in different construction fields. Results: A total of 19 opinion articles were finally included in the study and 29 experts were involved. The suggestions of experts on the construction of China's disease prevention and control system were summarized into four aspects. Conclusion: The COVID-19 pandemic is a challenge to the existing public health epidemic prevention and control system in China, and also an important opportunity for the development and construction of the related system.

Objective:To observe the effects of medium and long-term insulin pretreatment on the activity of main oxidase and antioxidant enzyme in the myocardium of burned rats with delayed fluid resuscitation.Methods:According to random number table method, forty male Sprague-Dawley (SD) rats were divided into pseudo-burn group, burn delayed resuscitation group, insulin glargine pretreatment group and neutral protamine hagedorn (NPH) insulin pretreatment group, with 10 rats in each group. 30% total body surface area (TBSA) as Ⅲ degree scald model was prepared by bathing the back of rats in 95 ℃ hot water for 15 s; the rats in the pseudo-burn group were immersed in 37 ℃ warm water for 15 s as control. Insulin glargine pretreatment group, NPH insulin pretreatment group and burn delayed resuscitation group were injected subcutaneously with insulin glargine, NPH insulin, and normal saline 1.0 U·kg -1·d -1 2 hours after injury, and intraperitoneal injection of normal saline 40 mL/kg simulated delay resuscitation 6 hours after injury. The pseudo-burn group didn't receive medicine and delayed resuscitation. Abdominal aortic blood samples and heart tissue were collected immediately after simulating scald in the pseudo-burn group, and 24 hours after scald in three burn groups. Blood glucose, xanthine oxidase (XOD), myeloperoxidase (MPO), CuZn-superoxide dismutase (CuZn-SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) of the heart tissue were determined by spectrophotometry. Results:Compared with the pseudo-burn group, the burn delayed resuscitation group have significantly higher blood glucose level and the XOD and MPO in the heart tissue, while significantly lower CuZn-SOD, CAT, and GSH-Px in the heart tissue. Compared with the burn delayed resuscitation group, insulin glargine pretreatment group and NPH insulin pretreatment group have lower blood glucose level and heart tissue XOD [blood glucose (mmol/L): 6.37±1.22, 6.66±1.45 vs. 9.47±0.80; XOD (U/g): 271.93 (261.59, 275.91), 285.32 (251.96, 297.29) vs. 363.37 (354.12, 377.76), all P < 0.05], while significantly higher heart tissue CuZn-SOD, CAT, and GSH-Px [CuZn-SOD (U/g): 0.13±0.01, 0.14±0.01 vs. 0.10±0.01; CAT (U/g): 29.17±7.28, 27.16±7.37 vs. 18.36±4.53; GSH-Px (U/g): 0.33 (0.16, 0.41), 0.30 (0.17, 0.41) vs. 0.07 (0.04, 0.11), all P < 0.05]. MPO activity in insulin glargine pretreatment group was significantly lower than that in burn delayed resuscitation group (U/g: 0.016±0.002 vs. 0.020±0.002, P < 0.05), but there was no significant difference between insulin pretreatment group and NPH insulin pretreatment group (U/g: 0.019±0.003 vs. 0.020±0.002, P > 0.05). There was no significant difference in the blood glucose, and activities of XOD, MPO, CAT, GSH-Px between insulin glargine pretreatment group and NPH insulin pretreatment group, but the activity of CuZn-SOD in NPH insulin pretreatment group was further higher than that in insulin glargine pretreatment group (U/g: 0.14±0.01 vs. 0.13±0.01, P < 0.05). Conclusions:Medium and long-term insulin pretreatment can improve the antioxidant capacity of myocardium in delayed resuscitation rats after burns, inhibit the production of reactive oxygen species and improve the scavenging capacity of reactive oxygen species. However, only CuZn-SOD activity is different between the two groups, and further study needs to be carried out to determine whether it is related to the type if insulin.

To improve the blast resistance of elite rice restorer line Fuhui 673, 3 blast resistance genes Pi-1, Pi-9 and Pi-kh were introduced into Fuhui 673 from a good-quality restorer line Jinhui 1059 through 3 successive backcrosses followed by one selfing using the technique of marker-assisted selection. Ten near-isogenic lines (NILs) of Fuhui 673 carrying the 3 introduced resistance genes were created. Genotype analysis using 68 SSR markers evenly distributed in the genome indicated that 92.96%-98.59% of the NILs' genetic background had been recovered to Fuhui 673. Both indoor and field resistance tests indicated that the NILs and their hybrids with sterile line Yixiang A were all resistant to rice blast, with resistance levels significantly higher than those of controls Fuhui 673 and hybrid Yiyou 673 (Yixiang A  Fuhui 673). In addition, among the 10 hybrids between the NILs and Yixiang A, 2 showed significantly higher yield than and 4 displayed similar yield to that of control Yiyou 673, suggesting that most of the NILs retained the elite characteristics of Fuhui 673. Two new hybrid rice cultivars Liangyou 7283 and Jintaiyou 683 from NIL Line 9 showed high yield, good resistance to blast and moderate growth period in regional trial, suggesting that the NIL Line 9 has a good prospect for application.
