Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

Objective To investigate the effects of software follow-up mode application on stigma sense,social function and survival quality in the patients with schizophrenia.Methods A total of 100 inpa-tients with schizophrenia in the psychiatric department of this hospital from January to December 2023 were selected as the study subjects and divided into the observation group(software follow-up)and the control group(telephone follow-up)according to different follow-up modes,50 cases in each group.At discharge from hospital and in 4,8,12 weeks after discharge,the Chinese version of Stigma Scale for Mental illness(SSMI-C)was adopted to evaluate the stigma sense of the patients,the Social Disability Screening Schedule(SDSS)was used to evaluate the patients'social function,the patients'survival quality was evaluated by the Generic Qual-ity of Life Inventory-74(GQOLI-74).The changes of above scores were compared between the two groups.Results The SSMI-C,SDSS and GQOLI-74 scores at discharge from hospital had no statistical difference be-tween the two groups(P＞0.05).Compared with at discharge from hospital,the SSMI-C and SDSS scores in 4,8,12 weeks of follow up in the two groups were decreased,the GQOLI-74 score was increased,moreover the scores of SSMI-c and SDSS in the observation group were lower than those in the control group,the GQOLI-74 score was higher than that in the control group,and the differences were statistically significant(P＜0.05).Conclusion Conducting the regular follow-up on discharged patients with schizophrenia by the follow-up soft-ware could reduce the stigma of the patients,improve the social functional defect and improve the survival quality.

Objective:To evaluate the quality of critical patient handover practice between emergency room and intensive care unit (ICU) nurses, and to provide a basis for structured handover process.Methods:From March to July 2023, a total of 223 pairs of nurses in emergency room and ICU (including EICU) of 5 Class 3 Grade A general hospitals in Suzhou were selected as the research objects by using cross-sectional survey method and convenience sampling method. Self-designed general information questionnaire and Patient Handover Practice Quality Scale were used to investigate the included 223 pairs of nurses in emergency room and ICU on the current situation of handover time and quality.Results:A total of 211 pairs of nurses were included, including 286 females (67.8%) and 136 males (32.2%). The average age of emergency department nurses was (27.31 ± 2.17) years old, and ICU nurses was (26.96 ± 3.04) years old. The total scores of the patient handover practice Quality Scale for nurses in the emergency room and ICU were (45.25 ± 6.26) and (43.55 ± 7.19) points respectively, and the scores of the information transmission dimension were (20.47 ± 5.43) and (17.66 ± 3.45) points. The scores of common understanding dimension were (7.59 ± 2.31) and (8.58 ± 2.46) points. The scores of work atmosphere dimension were (7.93 ± 2.11) and (8.39 ± 2.29) points. The scores of handover situation dimension were (5.33 ± 1.30) and (5.70 ± 1.53) points, and the differences were statistically significant ( t values were - 6.35-4.22, all P<0.05). There were statistically significant differences in the scores of handover practice quality between emergency room nurses and ICU nurses according to specialization, education background, working years and job category ( t values were - 4.91-2.56, all P<0.05). Conclusions:Emergency room nurses and ICU nurses have different requirements and expectations for handover procedures, so it is necessary to build a structured handover practice framework and carry out personalized handover practice training, in order to achieve the consistency of handover content and improve the quality of critical patients handover practice.

Objective:To understand cytomegalovirus (CMV) infection status in hospitalized preterm infants who were fed by their own mother's frozen breast milk.Methods:This retrospective study enrolled breastfed neonates with gestational age less than 32 weeks or birth weight less than 1 500 g who were born and admitted to Gynecology and Obstetrics Hospital of Fudan University from January 2018 to December 2020. Clinical data of the babies and their mothers were collected and analyzed, including CMV DNA results of breast milk and urine samples of the subjects by fluorescence quantitative polymerase chain reaction. Chi-square test (or Fisher's exact probability test), two independent samples t test, and Mann-Whitney U test were used for the statistical analysis. Results:A total of 94 parturients and their 103 premature infants (including nine pairs of twins) were included. CMV DNA of breast milk was noted for positive in 75 cases (including eight pairs of twins) and for negative in 28 cases (including one pair of twins). Out of the 75 preterm infants born to mothers with positive CMV DNA breast milk, 67 (including eight pairs of twins) were switched to frozen breast milk (－20 ℃ for 72 h), and six of them were infected by CMV(9.0%) without any treatment. All of the 103 infants were divided into two groups: the frozen milk fed group ( n=67) or fresh milk fed group ( n=36). In the frozen milk fed group, the CMV DNA was mainly detected during 2-8 weeks postpartum with copy number reaching the peak at 8th week. And those infants in the frozen milk fed group, whose mother's breast milk CMV DNA was positive, was further divided into CMV infected ( n=6) or CMV non-infected groups ( n=61) according to the urine test results. Moreover, compared with the non-infected group, the average [22.7(3.0-95.7)×10 3 copies/ml vs 5.0(0.5-89.5)×10 3 copies/ml, Z=－2.218) and the highest[45.9(5.9-261.0)×10 3 copies/ml vs 9.8(1.2-766.0)×10 3 copies/ml, Z=－2.218] copy number of CMV DNA in the breast milk were higher in the CMV infected group (both P<0.05). The incidence of feeding intolerance[37.3% (25/67) vs 50.0% (18/36), χ2=1.550], neonatal necrotizing enterocolitis [0.7% (1/67) vs 0.0% (0/36)], bronchopulmonary dysplasia [28.4% (19/67) vs 27.8% (10/36), χ2=0.004], retinopathy of prematurity [20.9% (14/67) vs 8.3%(3/36), χ2=2.682], and late-onset sepsis [22.4% (15/67) and 30.6% (11/36), χ2=0.828] did not differ significantly between the frozen or fresh milk fed groups (all P>0.05). Conclusions:The incidence of breast milk-related CMV infection in those fed with frozen breast milk was low and does not increase the without increasing risks of related complications or leading to obvious clinical manifestations after infection. For preterm infants with gestational age <32 weeks or birth weight <1 500 g, frozen breast milk can be an alternative for mothers with CMV DNA positive breast milk.

With comparison of three different methods for the marking of amines compound, an optimal deri vatization method was selected.5-(2-Hydroxyethyl) benzoacridine (HBA) reacts with coupling agent N,N'-carbonyldiimidazole(CDI) to form an activated amide intermediate 2-(benzoacridin) ethyl-imidazole-1-carbox-ylate(BAEIC).BAEIC, which is dual-sensitive probe, reacts preferably with amino compounds at 80 ℃ in the presence of 4-dimethylaminopyridine(DMAP) catalyst in N,N-dimethylformamide(DMF) solvent to give the corresponding sensitively fluorescent derivatives with an excitation maximum at λ_(ex) of 280 nm and an emis sion maximum at λ_(em) of 510 nm.BAEIC-amine derivatives simultaneously exhibited high ionization potential with percent ionization (changing from 5.62% to 58.08% in aqueous acetonitrile and from 2.14% to 56.58% in aqueous methanol.Derivatives were not only sensitive to fluorescence but also to MS ionizable potential.The fluorescence detection limits(5/iV = 3) were 0.12-0.59 μg/L.The online APCI-MS detection limits were 1.9-14 μg/L(S/N=5).

In this paper we studied cryopreservation of Cyclamen persicum Mill. callus to avoid variations produced by sub-culture. The callus in the logarithmic phase after sub-culture were used for experiments. Firstly, the callus were pre-cultured in culture-medium containing 4%, 6% or 8% sucrose for different time periods, transferred to different cryoprotectants to directly cryopreserve or incubated for 2 hours at -20 degrees C, then submersed in liquid nitrogen, lastly thawed rapidly in a waterbath at 37 degrees C, and washed with liquid culture-medium containing the corresponding concentration of sucrose. Cell survival rate was computed after stained by Neutral Red, and SPSS 13.0 software was used for statistical analysis. The results showed that sucrose concentration, pre-culture time, cryoprotectants had various impacts on cell survival rate. We have developed a simple but effective protocol for the cryopreservation of callus of C. persicum. Of the different protocols tested, 4%sucrose, pre-culturing for 3 days, No. 9 cryoprotectant and freezing directly after 30 minutes at 0 degrees C results in the highest cell survival rate.
