Summary of the analysis and experience of quality control in the bacterial Room A sterilizer control: In order to prevent insufficient sterilization, necessary monitoring tags should be placed. For example: OK paper. 4.2 Incubator, refrigerator control: The incubator temperature should be 35 ± 1°C, the refrigerator temperature should be 2~8℃. These instruments should preferably have automatic temperature control attached, or laboratory personnel should record the temperature before quitting time each day. Generally, increased temperature is harmful to bacterial growth, while too low temperatures will slow or stop bacterial growth and reproduction, affecting bacterial separation and drug susceptibility results. 4.3 Loop vaccination, inoculation needles: The diameter of the loop vaccination should be 3mm, needle length should be 5~8cm. Each vaccination should be completely sterilized by flame before and after use, but vaccination should cool down to avoid burning bacteria and affecting separation. 4.4 Medium quality control: Note that the composition of the medium cannot be measured, and standard strains are not available. When purchasing medium, attention should be paid to its batch number and expiration date. Production should be marked with batch number, preparation time, preparer, and name. When sterilizing according to the nature and quantity of packaging of the medium, different methods and temperatures should be applied so as not to undermine the active ingredient identified difficulties. Carbohydrate medium 55.16~69.95kpa15min, general media use 103.43kpa15~30min range. In the production of blood agar, rabbit blood or sheep blood is the best choice. Try to avoid using human blood, as human blood contains various antibodies, complement, and antibiotics which may affect bacterial growth substances. If rabbit blood and sheep blood are true and selected, healthy animals unused antibiotics should be chosen. 4.5 Dye control: After preparing a good dye, known positive and negative bacteria should be selected to do the control to identify the performance of the dye. In addition, rigorous grasp of the staining technique and timing should be maintained when identifying unskilled dyeing. 4.6 Drug-susceptibility - Experience in quality control: Factors influencing susceptibility include the medium, susceptibility paper, and bacterial inoculation in three aspects. The medium has more complicated factors, but the pH of the bacteriological examination should be preferred for the appropriate susceptibility test medium, separate injection volume (thickness) and dry conditions. Skilled operation is required, where in 1cm² of the medium, 1O4 amount of logarithmic phase growth of test bacteria should be inoculated. Drug susceptibility paper potency under high temperature and humidity conditions will significantly reduce. Therefore, it must be stored in the refrigerator, paying attention to dryness and validity to avoid affecting the results. 4.7 Diagnostic serum quality: After the expiration date, it cannot be used; lower potency cannot be used, precipitate or flocculent substances due to contamination cannot be used. It should be stored in the refrigerator, not at room temperature. 4.8 Inspection workers, business plexus surgery quality training: To do a good job of quality control of micro-organisms, besides objective conditions, more importantly, EXAMINER legislation should establish a strong sense of professionalism and responsibility and provide service attitude for all clinical patients. Continue to strengthen basic skills training, learn from experienced teachers, or operate under the guidance of skilled examiners, strictly abide by rules and experimental principles, adhere to replace turns sitting pile, avoiding one of the three work styles. The bacteriological test quality control is directly related to the accuracy and reliability of bacteriological diagnostic results and also directly impacts disease diagnosis and treatment. My room started carrying out bacterial quality control late, with short start time, experimental conditions and equipment, and uneven technical level of personnel. According to our lab, we should start from the foundation to both old and new, strengthen technical operations training, improve professional theoretical level, continue to accumulate and sum up experience, strictly follow operating procedures and quality control procedures, strengthen the sense of quality, improve the overall level generally, striving to better engage in the bacterial quality control of my room.

Small peripheral lung cancer CT diagnosis review articles Wei Yi Branch, neonatal asphyxia, severe respiratory failure, convulsions, respiratory tract injury, infectious conjunctivitis, neonatal severe disease. Handling inappropriate and care is different and will quickly lead to neonatal death and disease progression. Now nearly years nursing experience as described below. An imaging method for early peripheral lung cancer generally has no clinical symptoms, so early detection of lesions is the most critical. With the continuous improvement of the level of modernization of diagnostic imaging equipment, the detection rate has greatly improved, especially in thin-layer high-resolution CT scanning and enhanced scan, which has been recognized as able to provide more valuable diagnostic information.
