The genus *Deinococcus* is actually a group of bacteria, not fungi, and it is commonly mistaken for a parasitic fungus affecting *Coprinus comatus*, often referred to as the "chicken claw" mushroom. Although not a true fungus, *Deinococcus* species are known for their extreme resistance to environmental stressors such as radiation and desiccation. However, in the context of mushroom cultivation, certain bacterial contaminants can mimic fungal infections and cause significant damage to crops. To prevent such issues, a comprehensive approach involving environmental control and pathogen reduction is essential.
**Preparation of Cultivation Materials**
1. **High-quality raw materials**: Use fresh, dry, and mold-free components to ensure a clean growing medium.
2. **Optimized formula**:
- Formula 1: 18% cottonseed hulls, 28% corn cobs, 35% mushroom waste, 10% bran, 3% cake meal, 1.5% gypsum, 1.3% compound fertilizer, 0.2% fungicide, 3% quicklime, and 60-65% water.
- Formula 2: 96% cottonseed hulls, 1% gypsum, 3% quicklime, and 60-65% water.
- Formula 3: 38% corn cobs, 37% cottonseed hulls, 10% bran, 10% corn flour, 1% sugar, 1% fertile soil, 3% quicklime, and 60-65% water.
3. **Fermentation before sterilization**: The fermentation process should result in a brown-colored medium with abundant actinomycetes, a pleasant aroma, and a pH of 7.5–8. After fermentation, sterilize by heating the material to 100°C for 8–10 hours to eliminate pathogens.
**Cultivation Methods and Precautions**
1. **Bag planting**: This method helps prevent the spread of mycelium and makes it easier to identify and remove infected bags promptly. When using a shed, small shelters can be added to control humidity, reduce bacterial growth, and maintain COâ‚‚ levels that inhibit the development of the "chicken claw" fungus.
2. **Environmental disinfection**: Disinfect the growing area by spraying 5% formaldehyde or fumigating for 1–2 days to kill residual pathogens.
3. **Soil selection and treatment**: Choose fertile, uncontaminated soil and avoid areas where the chicken claw fungus was previously grown. Sun-dry the soil for 2–3 days, then mix with 2% quicklime to sterilize and adjust the pH. For each cubic meter of soil, apply 2.5 kg of 5% formaldehyde mixed with 200 times diluted dichlorvos, cover with plastic, and let it sit for 1–2 days before airing out before use.
4. **Clean watering**: Ensure that irrigation water is clean and free from contamination. A lime spray can also be used to maintain hygiene.
5. **Adequate ventilation**: High temperature and humidity are key factors in the development of the chicken claw fungus. Maintain good airflow, especially when temperatures rise.
6. **Avoid high temperatures during the growing season**: Spore germination of *Coprinus comatus* occurs best above 25°C, leading to higher infection rates during late spring, early summer, or summer-to-autumn periods. The most common time for outbreaks is between September and October. By managing temperature and humidity, growers can significantly reduce the risk of infection and improve crop yield.
POCT Analyzer
The characteristics of POCT devices determine that they can play an important role in primary medical institutions. In order to standardize and strengthen the application of on-site rapid testing in primary medical and health institutions, promote the rational allocation, safe and effective use of POCT in primary medical and health institutions, give full play to its use value, and ensure the healthy development of medical and health services, "On-site Point-of-care Testing (POCT) Primary The Expert Consensus on the Application of Medical and Health Institutions (hereinafter referred to as the "Consensus") came into being. The consensus was published in the 2019 "China Medical Equipment" magazine after first draft writing, 2 expert on-site discussions, 2 expert online review meetings, and 3 submission revisions. The formulation of the consensus will greatly promote the management standards of the POCT industry, continuously increase the training of grass-roots personnel, deeply understand the application requirements of POCT at the grass-roots level, and promote the rapid development of the POCT industry.
Point-of-care testing (POCT) represents a fruitful method in today's hospitals in terms of patient care and cost management. Its application enables some of the testing items originally undertaken by the central laboratory to be transferred to the clinical departments and patient beds that need it. side. For blood gas analysis technology, POCT has shown great advantages.
Our blood gas analyzer is small and portable, beautiful in appearance, accurate in results and good in stability. It is a blood gas analysis platform with both appearance and strength. It can be used not only in the central laboratory department, but also at the bedside of patients to meet the bedside detection needs of clinical departments such as hospital ICU, emergency, anesthesia, respiratory, neurology, etc. It realizes true POCT blood gas analysis and provides more advantageous assistance for clinical practice.
