In this experiment, in order to screen excellent Tibetan chicken breeds, common Tibetan chickens in Shigatse city were divided into four feather colors: black, white, red, and yellow based on feather color. The egg production performance and egg quality were measured separately, providing technical support for cultivating excellent egg type Tibetan chicken breeds. According to feather color, the Tibetan chickens were divided into four experimental groups, each experimental group had 160 Tibetan chickens of 150 days of age, and the three-dimensional 3-layer cage mode was implemented, with 8 replicates in each group and 20 chickens in each replicate. The experiment period was 30 days. All the four experimental groups were fed a basic laying diet, freely collected food and water, and were regularly immunized. The results showed that the average laying rate in black feather group was significantly higher than that in yellow feather group and red feather group (P<0.05); the average egg weight and average feed to egg ratio in yellow and red feather groups were significantly higher than those in black feather groups and white feather groups (P<0.05); the survival rate was not significantly different (P>0.05). There were no significant differences in egg quality index; eggshell strength and egg shape index among experimental groups (P>0.05); eggshell thickness was significantly different among all groups (P<0.05); the protein height of black feather group was significantly higher than that of white feather group, red feather group and yellow feather group (P<0.05); the Hagar unit of black feather group, white feather group and red feather group was significantly higher than that of yellow feather group (P<0.05); black feather group was slightly better than other experimental groups. There were no significant differences in egg color index and brightness among experimental groups (P>0.05); in terms of redness and yellowness, the red feather group was significantly higher than the other three experimental groups (P<0.05). The results show that the black feather Tibetan egg shell is white, and its egg production performance and egg quality are superior to the other three feather colors, making it suitable for further selection and breeding towards egg type Tibetan chickens.

Objective To analyzing changes of indicators related to intestinal barrier damage, neurotransmitters and inflammatory mediators in patients with irritable bowel syndrome (IBS) in the plateau environment, and explore the underlying pathogenesis of IBS. Methods A prospective cohort observation was conducted on 81 healthy male Han Chinese volunteers who were admitted to Lhasa of Tibe from plain. The study lasted for one year. During the one-year follow-up, 13 patients who developed IBS (Rome IV) were selected as the study subjects. Additionally 11 participants who remained healthy were randomly selected as the control group (named NC). Eleven participants who entered Lhasa from plain within one week and did not develop acute mountain sickness were randomly selected as the NC early group. Serum levels of diamine oxidase (DAO) and intestinal fatty acid-binding protein (I-FABP), 5-hydroxytryptamine (5-HT), interleukin (IL)-6, IL-17A and lipopolysaccharide (LPS) were measured using enzyme-linked immunosorbent assay (ELISA). At the end of the follow-up period, colonoscopy and intestinal mucosal biopsy were performed in 9 cases of IBS, while colonoscopy was performed in 4 cases of NC. Results Colonoscopy and pathological results of IBS patients in plateau environment suggested mild inflammation of intestinal mucosa. Compared to the NC early group, the NC group showed increased levels of 5-HT, DAO, I-FABP, IL-6, IL-17A and LPS at 3 months after entering Lassa, and increased levels of 5-HT, I-FABP, IL-6, and LPS at 6 months (P＜0.05). Compared with the NC group, the IBS group showed decreased levels of 5-HT and LPS at 3 months after entering Lhasa (P＜0.05). Serological indexes of NC group at 6 months were lower than those at 3 months in the NC group (P＜0.05). There were no significant differences in serological indexes at 3 and 6 months of the IBS group. Conclusion Indicators of intestinal mucosal barrier damage, neurotransmitters and inflammatory mediators might be involved in the development of IBS in plateau environment. [ABSTRACT FROM AUTHOR]

The discrete element method and statistical analysis of contact networks were combined to study the packing structure and it's crystallization for disk systems under isotropic compression. In the discrete element simulation, the dispersion degree was controlled by changing the particle size ratio of large and small particles to make the system become monodisperse or approximate monodisperse. The percentage of contact types was used to describe the statistical characteristics of contact structure. The curves of the pressure of the system and the percentage of various contact types varying with the packing fraction were given, the influence of friction and particle size ratio on these curves was studied, and the effects of friction and monodisperse degree on the crystal lattice structure were emphatically discussed. The simulation results show that with the increase of the number of disks, the critical packing fraction increases gradually, with the increase of friction and particle size ratio, the critical packing fraction decreases gradually. Friction and the level of monodispersity are the main factors affecting the extent of crystallization of contact structure. In the monodisperse disk system, when the friction coefficient is small, triangular lattice clusters are easily formed in the continuous compression process of the system, with the increase of friction coefficient, the extent of crystallization decreases. When the friction coefficient is greater than 0. 8, it is difficult to form triangular lattice clusters. In the approximate monodisperse disk system, only when the level of monodispersity is very high, the continuous compression process will lead to obvious crystallization. With the increase of particle radius ratio, the crystal lattice structure is more difficult to appear, and the system usually forms disordered packing. [ABSTRACT FROM AUTHOR]

Despite the importance of ontogenetic data on early diverging euarthropods to our understanding of the ecology and evolution of past life, the data are distinctly lacking, as reconstructing life histories of fossil animals is often challenging. Here we report the growth trajectory of frontal appendages of the apex predator Amplectobelua symbrachiata , one of the most common radiodont arthropods from the early Cambrian Chengjiang biota (c. 520 Ma) of China. Analysis of 432 specimens (9.1–137.1 mm length; 1.3–25.6 mm height) reveals that appendages grew isometrically, with an estimated maximum size of the whole animal of c. 90 cm. Individuals grew rapidly compared to extant arthropods, as assessed using the electronic length-frequency analysis (ELEFAN) approach. Therefore, we show that the Cambrian apex predator A. symbrachiata was an extremely fast-growing arthropod, with an unusual life history strategy that formed as part of the escalatory 'arms race' that shaped the Cambrian explosion over 500 Ma.

BACKGROUND: The landing test can effectively observe the biomechanical indexes of the lower limbs of patients with chronic ankle instability, analyze the balance adjustment strategies that affect the stability of chronic ankle instability posture, and provide a valuable reference for chronic ankle instability patients to avoid re-injury and clinical rehabilitation after injury. OBJECTIVE: To analyze the effects of vision on the balance of chronic ankle instability and the changes in balance adjustment strategies by observing the kinematics and kinetics of chronic ankle instability patients during landing with and without vision. METHODS: Totally 31 patients with chronic ankle instability landed on a single leg from a 40 cm platform with their eyes open and closed. The dynamic and kinematic data during the landing process were collected using a three-dimensional motion capture system. The difference in landing between the healthy and the ill side legs under the two conditions was compared by paired t-test. RESULTS AND CONCLUSION: (1) Dynamic indexes: The relative value of the peak ground reaction force in the front, rear and vertical directions of the affected ankle joint when eyes were closed was greater than that when eyes were open, and the peak ground reaction force in the vertical direction appeared later than that when eyes were open (P < 0.05). (2) Kinematics indexes: The flexion angle of the knee of the healthy and affected sides when touching the ground was greater under the condition of closed eyes than under the condition of open eyes (P < 0.05). The maximum flexion angle and feedforward angle of the affected knee and ankle were greater than those of the affected side with eyes open (P < 0.05). The time of landing stability was longer than that of eye opening (P < 0.05). (3) It is indicated that under the condition of removing visual input, the peak of ground reaction force increases, the contact angle joint increases, and the time to stabilization of chronic ankle instability is prolonged during landing in patients with chronic ankle instability, which increases the probability of landing injury. Visual maintenance of the balance of chronic ankle instability patients cannot compensate for the vestibular sense and proprioception. [ABSTRACT FROM AUTHOR]

Objective Achieving efficient rapid demulsification of water-in-oil emulsion constructed of oil with high viscosity was realized. Methods The g-C3N4 was prepared from melamine by thermal polymerization method. The composite filter cake was prepared by mixing super-hydrophilic g-C3N4 with diatomite, and the high viscosity water-in-oil emulsion was quickly demulsified by pumping and filtering. ResultsThe filter cake containing 1.5 wt% g-C3N4 with 0.5 cm thickness can realize completely demulsified, which the emulsion with water content less 6 wt% and droplet size larger than 2.32 μm. The demulsification rate of 20 kPa vacuum degree can reach 3.57 L/min, the demulsification efficiency is 97.36%, and the oil recovery rate is above 99.72%. Thickening the filter cake can be used for demulsification of emulsion with higher water content. Such attractive demulsification effect is caused by the simultaneous action of strong affinity of g-C3N4 to water and the crushing effect by micropores of diatomite. Conclusion The g-C3N4/diatomite composite filter cake can be effectively used for efficient rapid demulsification of water-in-oil emulsion with promising application prospect. [ABSTRACT FROM AUTHOR]

Objective　This paper provides a brief overview of the epidemiology of colorectal cancer in China and around the world, and discusses how to prevent colorectal cancer to reduce its disease burden. Method　Using the official database of GLOBOCAN 2020, the China Cancer Registry Annual Report compiled by the National Cancer Center, and data from CONCORD-3. Data management was performed by Microsoft Excel 2016 and R 4.2.1 Relevant graphs were generated using the ggplot2 package for result visualization. Result　An estimated 1 931 590 people were diagnosed with colorectal cancer worldwide in 2020 with an age-standardized incidence rate of 19.5 per 100 000. There were about 935 173 deaths caused by colorectal cancer internationally, with an age-standardized mortality rate of 9.0 per 100 000. Overall, colorectal cancer was the fourth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020. In China, the age-standardized incidence rate and mortality rate of colorectal cancer was 17.3 per 100 000 and 7.8 per 100 000, respectively. Gender differences in trends were observed, with a decreasing trend in incidence and mortality among females and an increasing trend in incidence and mortality among males. The primary risk factors for colorectal cancer include age, genetic factors, gastrointestinal disorders, dietary habits, and lifestyle et al. Conclusions　Colorectal cancer poses a significant burden globally and in China. The occurrence of colorectal cancer is closely related to physiology, genetics, behavioral habits, lifestyle, and disease factors. To better control the colorectal cancer burden with the lowest cost, specific measures should be taken to reduce exposure to established risk factors. By combining the disease prevention and control strategies of tertiary prevention in China with the characteristic factors of colorectal cancer, the incidence and mortality of colorectal cancer may be effectively controlled.

The underground diaphragm wall-pile composite foundation is a new type of variable rigidity foundation which combines diaphragm wall with pile foundation. From the design concept, the combination of underground diaphragm wall-pile foundation has a better ability to resist lateral deformation and both economic. However, there is still a lack of systematic research on the mechanism of this new type of foundation from the perspective of mechanical characteristics. Based on the large-scale on-site model test conducted, the stress of the new type of composite foundation under horizontal load was simulated, and the variation law of load and displacement of the foundation were obtained by comparing the test and numerical simulation results. By analyzing the deformation characteristics of composite foundations under different levels of load, the load transfer law of the foundation was revealed, and a preliminary approximate calculation of the horizontal bearing capacity of the pile wall composite foundation was carried out. The results show that the composite foundation under horizontal load has been inclined to failure as a whole. The bending moment of the wall is much larger than that of the pile, the bending moment of the pile wall increases gradually with the increase of the loading grade, and the position of the maximum bending moment as well as the peak bending moment remain unchanged. With the increase of burial depth and load, the earth pressure on the wall side presents a non-linear change, the earth pressure on the side of the underground diaphragm wall is greater than that on the middle, and the maximum earth pressure appears in the middle and lower part of the underground diaphragm wall.
