The unique characteristics of the deep space environment, microgravity, cosmic radiation, and extreme temperature fluctuations, are emerging as major driving forces for pharmaceutical innovation. These factors provide new avenues for optimizing drug formulations, improving crystal structure quality, and accelerating the discovery of therapeutic targets. Advances in deep space research not only help overcome critical bottlenecks in terrestrial drug development but also promote progress in structure-based drug design and deepen understanding of cellular stress-response mechanisms. Current progress in space-based pharmaceutical research primarily includes the study of disease mechanisms under microgravity, protein crystallization in microgravity, and drug development utilizing deep space radiation and resources. However, the operational complexity, high costs, and limited data reproducibility of space experiments remain key challenges hindering widespread application. Looking ahead, with the integration of automation, artificial intelligence analysis, and on-orbit manufacturing, deep space drug development is expected to achieve greater scalability and precision, opening a new frontier in biopharmaceutical science.

The teaching laboratory is the central place to teach lab courses to undergraduate students. It is thus critical to evaluate how lab skills of students will be affected by the management of this lab. This study attempts to introduce the 6S concept, referring to "Seiri", "Seiton", "Seiso", "Seiketsu", "Shisuke", and "Safety", to the management of teaching laboratory, in particular, to the management of environments, safety, item deposition, reagents and consumables in the laboratory. We find that applying the "6S" management maintains a tidy lab environment, facilitates teaching the lab skills, and improves the quality of teaching, which together achieves the goal of education with the atmosphere. This study can provide a guideline for establishing and managing teaching laboratories in universities.

Family-based cohort study is a special type of study design, in which biological samples and environmental exposure information of the member in a family are collected and related follow up is conducted. Family-based cohort study can be applied to explore the effect of genetic factors, environmental factors, gene-gene interaction, and gene-environment interaction in the etiology of complex diseases. This paper summarizes the objectives, methods and results, as well as the opportunities and challenges of the family-based cohort study on common chronic non-communicable diseases in rural population in northern China.

PURPOSE: The study aimed to compare the physical activity of hematopoietic stem cell transplantation (HSCT) patients with healthy people (HP). METHODS: The research design of this study was cross sectional and, descriptive study. It was conducted from January 26th to May 22nd, 2013. We matched HSCT patients to HP based on age and gender, and measured physical activity using a pedometer. Patient's clinical information were gathered by the medical record reviews. RESULTS: The number of steps was significantly less in HSCT patients (HSCT: 214 (7~3,373) vs HP: 7,921 (3,180~17,539), p<.001). Physical activity time was significantly less in HSCT patients (HSCT: 840 (680~1,320)min vs HP: 990 (540~1,090)min, p<.001). Step count showed a significant relationship with platelet count (r=.40, p=.004). CONCLUSION: HSCT patients perform very low intensity of physical activities. The study shows the necessity to apply programs to promote physical activities in isolation rooms for patients undergoing HSCT.

Oxygen enrichment of room air is an effective way to resist hypoxia at high altitude, but it may introduce a potential fire hazard. In common, the burning rate of light and thin homogeneous solid in oxygen enriched atmosphere was used to assess the fire hazard. For the purpose of measuring the burning rate of light and thin homogeneous solid in oxygen enriched atmosphere, we used the methods of laser contact ignition and direct calculation of burning rate, and invented a device that includes mixing gas system, ignition equipment, system of measuring the burning rate and self-made specimen frame. By using the homemade device, we studied the burning rate of filter paper under low pressure and in oxygen-enriched atmosphere and in that of the oxygen concentration of reached stationary burning rate. The results showed that this device was simple, and could obtain the burning rate of light and thin homogeneous solid quantitatively.

This paper developed an experimental animal cabin with ATM/LP and low oxygen and high carbon dioxide. It is based on the unitized design of modern transmission technology, industrial measurement modules and configuration software. The cabin successfully simulated an enclosed environment of low oxygen and high carbon dioxide at constant pressure, automatically measured and controlled the concentrations of oxygen and carbon dioxide as well as temperature and humidity in the cabin for the first time. The system provided a technology platform for the equipment supporting clinical COPD study. The result is accurate, stable and reliable and can realize automatic measurement and control of cross. The clinical applications show that the cabin with accurate measurement and control is practical and reliable.

OBJECTIVETo explore the feasibility of the animal experimental cabin to copy the animal models with ATM/LP and low oxygen and high carbon dioxide environment.

METHODS60 SPF-class male SD rats were divided into two groups, 20 for normobaric hypoxia control experiments and the other 40 for hypobaric hypoxia control experiments. For each group, examine the pulmonary arterial pressure and carotid arterial pressure indicators of rats by using the multi-detector measurement of physiological, and observe the pulmonary vascular changes in the structure.

RESULTSThe ATM/LP and low oxygen and high carbon dioxide environment can promote the formation of pulmonary hypertension and accelerate changes in pulmonary vascular remodeling, promoting right ventricular hypertrophy.

CONCLUSIONClinical applications showed that the animal experimental cabin was observing and controlling accurately, safe, reliable, and the results was reproducible. It can successfully copy the regular low-pressure hypoxia and hypercapnia environment pulmonary hypertension model, in order to study the physiological mechanism of a variety of circulation and respiratory diseases caused by oxygen-poor and provide an experimental technology platform.
