Objective:To compare the medical costs of using standard fortified donor human milk (DHM) or preterm formula (PF) to supply very low birth weight [VLBW, defined as birth weight (BW) ≥1 000 g but <1 500 g] and extremely low birth weight (ELBW, defined as BW <1 000 g) premature infants with insufficient maternal breast milk.Methods:VLBW and ELBW preterm infants hospitalized in Peking Union Medical College Hospital from September 2017 to October 2020 were retrospectively enrolled and assigned into DHM group and PF group based on complementary feeding methods. The cost of parenteral nutrition (PN), cost of antibiotics, and total medical expenses during hospitalization were compared between the two groups.Results:A total of 89 infants were enrolled in this study, out of whom 50 was in the DHM group and 39 the PF group. The gestational age in DHM group and PF group were both (29±2) weeks. The BW of DHM group was 1 170 (919, 1 380)?g and that of PF group was 1 170 (1 010, 1 360) g. There were no significant differences in gestational age, BW, maternal age at delivery, delivery mode, gender ratio, proportion of small-for-gestational-age infants and length of hospital stay between the two groups (all P>0.05). The cost of parenteral nutrition in DHM group was significantly lower than that in PF group [3 500 (1 922, 5 704) Chinese yuan vs 7 995 (5 579, 10 788) Chinese Yuan, P<0.01]. The cost of antibiotics in DHM group was significantly lower than that in PF group [6 529 (2 265, 10 860) Chinese Yuan vs 13 676 (10 480, 18 506) Chinese Yuan, P<0.01]. The difference in total medical expense during hospitalization showed no statistical significance between two groups ( P>0.05). Amorg VLBW preterm infants, the cost of PN, cost of antibiotics, total cost of hospitalization, and daily cost of hospitalization in HDM group was significantly lower than that in PF group (all P<0.05). In ELBW preterm infants, the cost of PN and the cost of antibiotics in HDM group were significantly lower than that in PF group (both P<0.05), but the total cost of hospitalization and the daily cost of hospitalization between two groups showed no significant difference (all P>0.05). Conclusions:When mother's own milk is insufficient, using donor human milk reduces the costs of PN and antibiotics in VLBW and ELBW preterm infants compared with using PF. In VLBW preterm infants, using DHM can also reduce the total and daily cost of hospitalization.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

Objective:To analyze the association between healthcare workers mental health,institu-tional supplies and facilities,inter-organizational coordination during infectious disease outbreaks,and the healthcare institution resilience.Methods:An online questionnaire survey was conducted among the healthcare workforce from 146 institutions in Beijing from January 13,2023 to February 9,2023,and a total of 1 434 eligible respondents were included.The sample comprised 408 responses from tertiary hos-pitals,117 from secondary hospitals,and 909 from primary care institutions.The resilience indicator for healthcare institutions was defined as the degree to which medical services met patient demands,with in-fluencing factors including physical factors,such as material shortages and facility space adaptation or ex-pansion,organizational factors such as information sharing and patient referral,and psychological factors were evaluated using job satisfaction(extrinsic satisfaction,intrinsic satisfaction),burnout(emotional exhaustion,depersonalization,reduced personal accomplishment),and depression status.Ordered mul-ticlassification Logistic regression was used to examine the impact of various factors on the degree to which healthcare services met patient needs;additionally,demographic factors that might influence institutional resilience were controlled.Results:During the emergency response phase,93％of hospitals maintained the capacity to meet patient needs,though tertiary hospitals demonstrated significantly higher rates of service inadequacy(21.05％).Material shortages were reported across all institutions,with tertiary hos-pitals experiencing more frequent multi-item shortages.Inter-institutional collaboration patterns revealed substantial variation:87.50％of primary care facilities,42.86％of secondary hospitals,and 31.58％of tertiary hospitals.Healthcare workers across all levels reported mild depressive symptoms and moderate-to-severe burnout levels.Regression analysis showed high satisfaction(overall satisfaction β=0.04,ex-trinsic satisfaction β=0.06,and intrinsic satisfaction β=0.08),low degree of job burnout(emotional exhaustion β=-0.04,depersonalization β=-0.07 and reduced personal accomplishment β=0.01),low degree of depression(β=-0.06)were significantly associated with higher healthcare institution re-silience.In addition,material shortages were significantly associated with lower resilience,and renova-tion and expansion of treatment spaces,and information sharing,were all associated with higher resilience.Demographic factors(age,gender,marital status,educational background,etc.)had no sig-nificant impact on resilience.Conclusion:Mental health status significantly influences healthcare institu-tion resilience.As human resources constitute the core asset of healthcare institutions,strategic optimiza-tion of workforce allocation and psychological support interventions can effectively strengthen resilience.Moreover,healthcare institution resilience is positively impacted by orderly material supply chains,timely resource distribution,and adaptive reconfiguration of clinical spaces.Finally,facilitating information sharing also enhances institutional resilience.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Objective To evaluate the short-term efficacy and safety of percutaneous liver puncture for local management of portal vein thrombosis(PVT).Methods Variations in thrombus,blood flow,and laboratory examination results were observed before and after percutaneous liver puncture in 197 patients with PVT,and the occurrence of comorbidities was recorded and followed up for one year after treatment.Results After treatment,the thrombus in the main portal vein vessels almostly disappeared in 119 patients(60.41％)with PVT,the thrombus had a significant reduction in 57 patients(28.93％),and the thrombus had a smaller change or an increase in 21 patients(10.66％);146 patients(74.11％)had smooth blood flow in the main portal vein vessels,29 patients(14.72％)showed significant improvement in blood flow,and 22 patients(11.17％)showed no significant improvement or worsening of blockage.The mean portal venous pressure was significantly lower than that before treatment(P＜0.001);thrombin time,activated partial thromboplastin time,and prothrombin time were prolonged compared to those before thrombolysis(P＜0.001),and fibrinogen were reduced compared to those before thrombolysis(P＜0.001).A total of 35 patients(17.77％)occured comorbidities during treatment.One year after treatment,196 patients(99.49％)with PVT survived,of which thrombus essentially disappeared in 141(71.94％),thrombus stabilized(or decreased)in 42(21.43％),and thrombus increased in 13(6.63％).Conclusion percutaneous liver puncture for local management of PVT is effective and reliable in the short-term and requires standardized management of the entire process.

A 67-year-old male patient with esophageal cancer received sintilimab and chemotherapy [sintilimab injection 200 mg by IV infusion, 1 day before chemotherapy, paclitaxel (albumin bound) 200 mg by IV infusion on day 1 and 300 mg on day 5, and nedaplatin 80 mg by IV infusion on day 1 and 70 mg on day 2, 21 days as 1 cycle] for 4 cycles. Later, due to mediastinal lymph node metastasis, the patient received sintilimab and palliative radiotherapy one time. Eight days later, the patient developed urinary frequency, urgency and pain, urine routine showed 638 red blood cells/μl, and 2 141 white blood cells/μl. The T-cell test for mycobacterium tuberculosis infection was positive, and cystoscopy showed diffuse redness and swelling of bladder mucosa. The patient was diagnosed with immune-related cystitis and bladder tuberculosis, which was considered to be related to sintilimab. Methylprednisolone sodium succinate and anti-tuberculosis treatment were given. After 5 days of treatments, the patient′s aforementioned symptoms were improved and the urine routine returned to normal. Afterwards, sintilimab was not used again and relevant symptoms did not recur.

Aim To investigate the intracellular up-take and target protein binding characteristics of two Bruton's tyrosine kinase inhibitors(BTKi)with differ-ent selectivities to provide further insights into the mechanisms of drug off-target-related bleeding risk.Methods Ibrutinib(non-selective BTKi)and za-nubrutinib(selective BTKi)were used as study drugs.After incubation of MEC-1 cells and human platelets with drugs,the cellular thermal shift assay(CETSA)was combined with Western blot to obtain the melting curve and isothermal curve to analyze the binding char-acteristics of the two drugs with the target protein BTK.After incubation of MEC-1 cells and human platelets with drugs,the concentrations of the two drugs were detected by liquid chromatography-tandem mass spectrometry(LC-MS/MS)to analyze the intracellular uptake of the two drugs.Results CETSA analysis confirmed that zanubrutinib was more selective for the target protein BTK compared to ibrutinib.LC-MS/MS analysis showed that both drugs were uptaken intracel-lularly by MEC-1 cells and platelets in a concentration-dependent manner.Conclusions While BTKi targe-ting BTK to B lymphocytes exerts therapeutic effects,off-target effects on platelets due to differences in their intracellular uptake,and target-binding characteristics may be one of the reasons for the differences in bleed-ing risk across selective BTKi.

Aim To explore the mechanism and mate-rial basis of Shenkang injection(SKI)in the treatment of renal fibrosis(RF)by bioinformatics and in vitro experiments.Methods The differentially expressed genes of RF were screened by GEO database.With the help of CMAP database,based on the similarity princi-ple of gene expression profile,the drugs that regulated RF were repositioned,and then the components of SKI potential treatment RF were screened by molecular fin-gerprint similarity analysis.At the same time,the core targets and pathways of SKI regulating RF were predic-ted based on network pharmacology.Finally,it was verified by molecular docking and cell experiments.Results Based on the GEO database,two RF-related data sets were screened,and CMAP was relocated to three common RF therapeutic drugs(saracatinib,da-satinib,pp-2).Molecular fingerprint similarity analysis showed that RF therapeutic drugs had high structural similarity with five SKI components such as salvianolic acid B and hydroxysafflor yellow A.Molecular docking results showed that salvianolic acid B,hydroxysafflor yellow A and other components had good binding abili-ty with MMP1 and MMP13,which were the core targets of SKI-regulated potential treatment of RF.Network pharmacology analysis suggested that the core targets of SKI were mainly enriched in signaling pathways such as Relaxin and AGE-RAGE.Cell experiments showed that SKI could significantly reduce the mRNA expres-sion levels of AGER,NFKB1,COL1A1,SERPINE1,VEGFC in AGE-RAGE signaling pathway and MMP1 and MMP13 in Relaxin signaling pathway in RF model cells,and significantly increase the mRNA expression level of RXFP1.Conclusions SKI can play a role in the treatment of RF by regulating Relaxin and AGE-RAGE signaling pathways,and its material basis may be salvianolic acid B,hydroxysafflor yellow A and other components.
