Objective:To explore the application value of inventory management model of medical consumables based on the joint inventory management(JMI)theory in the informationization management for medical consumables.Methods:By analyzing the existed problems in the management for medical consumables,and establishing a JMI model information system,the strategy of inventory management of JMI model was formulated to conduct predictive regulation and control,and management for distribution on the requirement of medical consumables.A total of 1200 batches of medical consumables that were used in clinical practice at Heyuan People's Hospital from October 2022 to September 2024 were selected.Based on different inventory management modes,593 batches of medical consumables from October 2022 to September 2023 were managed by using the conventional independent inventory management mode,and 607 batches of medical consumables from October 2023 to September 2024 were managed by using the inventory management model(model management)based on JMI theory for informationization management for medical consumables.The efficiency and quality of management for inventory between two kinds of inventory management modes were compared.Results:The ratio of monthly average consumables to inventory of medical consumables of using the model management mode was 0.468±0.060,which was higher than that of the independent inventory management mode.The monthly average times of emergency ordering,the monthly average times of stockouts,and monthly average times of non-emergency ordering were respectively(23.84±6.02),(5.69±2.28)and(20.57±2.66)times,all of which were lower than those of the independent inventory management mode,and the differences were statistically significant(t=11.249,7.539,8.854,9.654,P<0.05).The consumed times of inbound,information verification,query and statistics,and outbound of medical consumables of adopting the model management mode were respectively(1.18±0.40),(0.25±0.06)h,(0.73±0.35)h,and(0.53±0.22)h,all of which were lower than those of the independent inventory management mode,and the differences were statistically significant(t=50.621,87.351,61.524,43.806,P<0.05).Conclusion:The application of inventory management model for medical consumables based on the JMI theory in informationization management for medical consumables can improve management efficiency for inventory,and optimize structure of inventory,and reduce costs of inventory,and decrease the frequency of temporary procurement for medical consumables.

Evaluating the consistency of herb injectable formulations could improve their product quality and clinical safety, particularly concerning the composition and content levels of trace ingredients. Panax notoginseng Saponins Injection (PNSI), widely used in China for treating acute cardiovascular diseases, contains low-abundance (10%-25%) and trace saponins in addition to its five main constituents (notoginsenoside R₁, ginsenoside Rg₁, ginsenoside Re, ginsenoside Rb₁, and ginsenoside Rd). This study aimed to establish a robust analytical method and assess the variability in trace saponin levels within PNSI from different vendors and formulation types. To achieve this, a liquid chromatography-triple quadrupole mass spectrometry (LC-MS/MS) method employing multiple ions monitoring (MIM) was developed. A "post-column valve switching" strategy was implemented to eliminate highly abundant peaks (NR₁, Rg₁, and Re) at 26 min. A total of 51 saponins in PNSI were quantified or relatively quantified using 18 saponin standards, with digoxin as the internal standard. This study evaluated 119 batches of PNSI from seven vendors, revealing significant variability in trace saponin levels among different vendors and formulation types. These findings highlight the importance of consistent content in low-abundance and trace saponins to ensure product control and clinical safety. Standardization of these ingredients is crucial for maintaining the quality and effectiveness of PNSI in treating acute cardiovascular diseases.

Objective To investigate the value of multi-slice spiral CT (MSCT) in diagnosis of colorectal carcinoma. Methods MSCT images of 42 cases of colorectal carcinoma proved by surgery and pathology were retrospectively analyzed. Multiplanar reconstruction (MPR) in all cases, and curved planar reconstruction (CPR), shaded surface display (SSD), CT virtual colonoscopy (CTVC) and Raysum were performed in some of the cases. MSCT findings were analyzed in comparison with operative and pathologic features. Results The detecting rate and quatitative rate of colorectal carcinomas with MSCT were 100%,respectively.The accurate rates were 82.9%(29/35) and 100%(7/7) in detection of invasion of surrounding structures and metastasis in abdominal organs respectively,the sensitivity and specificity for detetion of lymph node metastasis were 71%(22/31) and 100% with MSCT imaging.Conclusion MSCT scan with multiform reconstruction techniques can make definite diagnosis of colorectal carcinoma, which is helpful for treatment plan.
