Objective:To understand the construction and problems of budget management system in public hospitals, and to provide countermeasures and suggestions for its continuous improvement and construction.Methods:Literature review was used to summarize the national policy requirements for comprehensive budget management system of these hospitals in China. Random sampling was used to select 109 public hospitals as pilots, and a questionnaire was customized from March to April in 2019, to investigate the current budget management and problems, with the data studied by descriptive statistical analysis.Results:Seventy-seven hospitals (70.64%) reported in self-appraisal their budget management as satisfactory and above, 78 hospitals (71.56%) had in place a comprehensive budget management system, 90 hospitals(82.57%) had in place a budget management committee, and 91 hospitals (83.49%) had in place refined budget preparation. The main problems were unclear budgeting requirements and nonstandard process, poor information integration and informationization, inadequate inter-department synergy, and poor alignment between business and finance.Conclusions:The public hospitals are recommended to enhance their comprehensive budget management system and their informationization, for full-process informationized management.

OBJECTIVE@#To study the effect of different melatonin treatment regimens on long-term behavior and white matter damage in neonatal rats with hypoxic-ischemic brain damage (HIBD), and to seek an optimal melatonin treatment regimen.@*METHODS@#Healthy Sprague-Dawley rats, aged 7 days, were randomly divided into four groups: sham-operation, HIBD, single-dose immediate treatment (SDIT), and 7-day continuous treatment (7DCT), with 8 rats in each group. A neonatal rat model of HIBD was prepared according to the classical Rice-Vannucci method. On day 21 after HIBD, the Morris water maze test was used to evaluate spatial learning and memory abilities. On day 70 after HIBD, immunofluorescence assay was used to measure the expression of neuronal nuclear antigen (NeuN) in the cerebral cortex and the hippocampal CA1 region of neonatal rats, and double-label immunofluorescence was used to measure the expression of myelin basic protein (MBP) and neurofilament 200 (NF200) in the corpus striatum and the corpus callosum.@*RESULTS@#The results of the Morris water maze test showed that the SDIT and 7DCT groups had a significantly shorter mean escape latency than the HIBD group, and the 7DCT group had a significantly shorter mean escape latency than the SDIT group (@*CONCLUSIONS@#Both SDIT and 7DCT can improve long-term behavior and reduce white matter damage in neonatal rats with HIBD, and 7DCT is more effective than SDIT.

Background: Freeze-drying is known as one of the best methods to preserve bacterial strains. Protectant is the key factor affecting the survival rate of freeze-dried strains. In addition, salinity, bacterial suspension concentration, drying time, and other factors can also affect the survival rate of strains to varying degrees. At present, there are relatively few studies on freeze-drying preservation of marine bacteria. In the present study, we performed the freeze-drying protectant screening and optimized the preservation conditions for Pseudoalteromonas nigrifaciens, which is widely distributed in marine environment. The protective effects of the screened protectants were verified by 18 other marine bacterial strains. Results: The results indicated that the combination of 5.0% (w/v) lactose, 5.0% (w/v) mannitol, 5.0% (w/v) trehalose, 10.0% (w/v) skim milk powder, 0.5% (w/v) ascorbic acid and 0.5% (w/v) gelatin was the best choice for the preservation of P. nigrifaciens. The suggested salinity and concentration of initial cell suspension were 10 g/L NaCl and 1.0 × 109 CFU/mL, respectively. Furthermore, stationary-phase cells were the best choice for the freeze-drying process. The highest survival rate of P. nigrifaciens reached 52.8% when using 5­10% (w/v) skim milk as rehydration medium. Moreover, the other 18 marine strains belonging to Pseudoalteromonas, Vibrio, Photobacterium, Planomicrobium, Edwardsiella, Enterococcus, Bacillus, and Saccharomyces were freezedried under the abovementioned conditions. Their survival rates were 2.3­95.1%. Conclusion: Collectively, our results supported that the protectant mixture and parameters were beneficial for lyophilization of marine bacteria

Objective To learn the current deployment and problems of medical equipment at 44 hospitals directly under or managed by the NHFPC,studying the correlation between the number of equipment deployment,and amount of outpatients/inpatients and inpatient surgeries for recommendations on scientific and rational deployment of medical equipment.Methods Literature review,expert consultation and questionnaire survey methods were used to study the use and problems in hospital equipment deployment.EpiData was used to build a database,and the means,standard variations and constituent ratios were applied for descriptive analysis of medical equipment deployment of the hospital departments.The data of hospital equipment usage and staffing,hospital beds,and service volume were subject to correlation analysis.Results 24 of the 44 hospitals were deployed with class-A medical equipment,covering eight types and 43 devices;the 44 hospitals were deployed with 441 class-B equipment of five types;the equipment types in great demand at such hospitals were MRI (77.27%),CT (70.45%),bioanalysis devices (68.18%),conventional radiation devices (52.27%),and conventional equipments (54.55%).The survey found a positive correlation ( P <0.05 ) between the equipments,and the amount of outpatients/inpatients and inpatient surgeries.Conclusions Hospitals should further establish and improve their deployment management system,rationalize their deployment procedures,and use scientific and rational deployment.Such approaches as equipment sharing,centralized management and performance appraisal could be called into play to improve equipment efficiency.

<p><b>BACKGROUND</b>Using magnetic resonance imaging, diagnosis of malignant meningioma from benign meningioma with atypical features is uncertain. We evaluated the value of lipid signal in differentiating intracranial meningiomas.</p><p><b>METHODS</b>1H-magnetic resonance spectroscopy (MRS) using a point resolved spectroscopy (TR/TE 1000/144 ms) sequences were performed on 34 patients on a 3.0 T scanner. Lipid peak located at 1.3 ppm was evaluated. MRS data from these tumours were compared with histopathological findings (including hematoxylin and eosin staining and KP-1 staining).</p><p><b>RESULTS</b>Twenty-nine meningiomas were histologically benign (eleven meningothelial, thirteen fibrous, four transitional and one microcystic), three were atypical, and two were anaplastic. Lipid signal was detected in ten cases: two anaplastic, three atypical, two fibrous and three meningothelial meningiomas. All voxels with lipid peak in the spectrum from the tumour were evaluated. With creatinine peak in the normal white matter chosen as internal standard, lipid/creatinine ratios of anaplastic, atypical and benign meningiomas were 0.844 +/- 0.027 (range from 0.725 to 0.994), 0.465 +/- 0.023 (range from 0.239 to 0.724), and 0.373 +/- 0.016 (range from 0.172 to 0.571) respectively. Highly significant differences were noted between anaplastic and the other two subtypes. Patchy necrosis was observed in anaplastic meningioma, while focal necrosis was noted in atypical meningioma with HE stain. However, no necrosis was found in benign group. KP-1 stain demonstrated histocytes containing lipids in the necrotic region of anaplastic and atypical meningioma.</p><p><b>CONCLUSION</b>The lipid signal at 1.3 ppm is a useful marker in evaluating the malignancy of intracranial meningiomas, especially in the differential diagnosis of anaplastic meningioma.</p>
