OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

[Objective] To investigate the infection and characteristics of hepatitis E virus among blood donors in Hangzhou. [Methods] A total of 5 075 blood samples of blood donors from Zhejiang Provincial Blood Center from September to November 2023 were collected, including 5 037 samples with normal ALT and 38 samples with elevated ALT (>50 U/L). Enzyme-linked immunosorbent assay (ELISA) was used to detect anti-HEV IgM, anti-HEV IgG and HEV-Ag. The Fisher test and Chi-square test were used to evaluate the difference in the reactivity rates of anti-HEV IgM and anti-HEV IgG among different levels of ALT. The distribution characteristics of HEV screening in blood donors were analyzed. Univariate and multivariate logistic regression were used to analyze the susceptibility factors of anti-HEV IgM and anti-HEV IgG seropositivity, and the anti-HEV IgM-reactive blood donors were followed up by telephone. [Results] The reactivity rates of anti-HEV IgM, anti-HEV IgG and HEV-Ag in 5 075 blood samples were 0.45%, 22.98% and 0%, respectively. There was no difference in the reactivity rates of anti-HEV IgM and anti-HEV IgG among different levels of ALT (P>0.05), and the results of univariate and multivariate logistic regression analysis showed that age was a risk factor for anti-HEV IgM and anti-HEV IgG reactivity in blood donors (P<0.05), while no difference in the reactivity rates of anti-HEV IgM and anti-HEV IgG among blood donors was noticed in gender, occupation and education level (P>0.05). [Conclusion] There is a potential risk of transfusion-transmitted HEV (TT-HEV) in Hangzhou, and a cost-effective HEV screening strategy needs to be established to continue regular HEV surveillance in Hangzhou to assess the risk of infection.

Objective To explore the mitochondrial dysfunction in glaucoma-related optic nerve injury and its effect on the apoptosis of retinal ganglion cells(RGCs).Methods The RGC-5 cells were incubated under elevated pressure(70 mmHg,1 kPa=7.5 mmHg)on the basis of standard atmospheric pressure(100 kPa)for 12 h,24 h,and 48 h,respective-ly.The RGC-5 cells cultured under the standard atmospheric pressure were selected as the blank group.The apoptosis of RGC-5 cells was detected through Annexin V/PI staining.The mitochondrial membrane potential(MMP)and reactive oxy-gen species(ROS)level were measured using the JC-1 staining and DCFH-DA fluorescent probe.The expression levels of B cell lymphoma-2(BCL-2)protein,BCL-2-associated X(BAX)protein,cleaved Caspase-3,and cytochrome C(CytC)pro-tein were detected using Western blot.Results Compared with the blank group,the MMP in the 12 h,24 h and 48 h groups significantly decreased(all P＜0.05).Compared with the blank group,the cell apoptosis and ROS level in the 24 h and 48 h groups significantly increased(all P＜0.05),while there was no statistically significant difference in the cell apop-tosis and ROS level between the 12 h group and the blank group(both P＞0.05).Compared with the blank group,the rela-tive expression levels of cleaved Caspase-3 and BAX protein in the 24 h and 48 h groups significantly increased(all P＜0.05),while the relative expression levels of cleaved Caspase-3 and BAX protein in the 12 h group showed no significant difference(both P＞0.05).Compared with the blank group,the relative expression level of BCL-2 protein in the 12 h,24 h and 48 h groups decreased,and the differences were statistically significant(all P＜0.05).Compared with the blank group,the relative expression level of Cyt C protein in the 48 h group significantly increased(P＜0.05),while the relative expression level of Cyt C protein in the 12 h and 24 h groups showed no significant difference(both P＞0.05).Conclu-sion After culture at 70 mmHg pressure,RGC-5 cells show increased apoptosis and mitochondrial dysfunction.The mito-chondrial damage at the early stage of stress injury may be closely related to exogenous apoptosis pathways.

Objective To analyze the current status and quality of existing obstetrics and gynecology enhanced recovery after surgery(ERAS)guidelines/consensus,understand the evidence-based practices in this field,and provide a basis for clinical decision-making.Methods A systematic search of PubMed,CNKI,and other databases,as well as NGC,SIGN,and websites of anesthesia societies domestically and internationally was conducted to obtain relevant guidelines and consensus on ERAS for gynecological surgery.The search was conducted from inception to July 1,2023,and the AGREE Ⅱ and RIGHT tools were used to analyze the current status and quality of the included guidelines/consensus,as well as to conduct a summary of the recommendations.Results A total of 5 guidelines and 10 consensus statements were included.The publication years were from 2018 to 2023,originating from the United States,China,Canada,and the United Kingdom.In the 6 areas evaluated using AGREEⅡ,clarity(66.06％)scored highest,followed by scope and purpose(56.67％),involvement of stakeholders(42.02％),and editorial independence(37.64％)with scores above 30％.The scores for rigor of development(26.88％)and applicability(4.17％)were relatively low.The same items among different evaluators indicated good consistency.The results of the scores in each area were as follows:A-level 2,B-level 13,and no C-level.Two high-quality guidelines were selected.The average RIGHT reporting rate was 44.38％.Subgroup analysis showed that guidelines were higher than consensus statements in the areas of rigor of development and applicability(P＜0.05),and that using GRADE was higher than not using(P＜0.05).The areas of rigor of development and clarity were higher in foreign guidelines than domestic guidelines(P＜0.05),and using evidence grading tools was higher than not using(P＜0.05).The summary of the recommendations showed that the quality of the evidence supporting the recommendations was uneven,and some recommendations were not specific enough.Conclusion The quality of the 15 included ERAS guidelines/consensus in obstetrics and gynecology is uneven,and 2 of them can be used as high-quality guidelines for clinical reference.The quality of evidence-based guidelines in foreign countries is higher,and the use rate of GRADE in foreign guidelines is high,most of which can provide clear recommendation strength and evidence level.Chinese guidelines/consensus are of lower quality compared to overseas,and methodology and report quality need further improvement.Overall,it is still necessary to strengthen the formulation of methods and reporting standards,improve the quality of evidence,and refine specific recommendations.

Objective To explore the value of lipoprotein-associated phospholipase A2(Lp-PLA2)in the diagnostic grading and prog-nostic assessment of pneumonia-associated acute respiratory distress syndrome(p-ARDS).Methods The study was a prospective ob-servational study.Fifty-seven patients with p-ARDS admitted to the ICU ward of Tianjin Hospital from January 2022 to August 2023 were included as the research subjects.Twenty-six pneumonia patients admitted to the general respiratory ward during the same period and 10 healthy individuals undergoing medical examinations were selected as the control group.Their serum samples were collected,and the samples from p-ARDS and pneumonia patients were obtained within 24 hours of admission.The levels of serum Lp-PLA2,in-terleukin 6(IL-6),and IL-8 were detected using the Luminex? multiplex test kit.The baseline data and laboratory test results,inclu-ding routine blood parameters,biochemical markers,C-reactive protein(CRP),procalcitonin(PCT),and D-dimer at admission,were collected from the patients with p-ARDS or pneumonia.The levels of serum Lp-PLA2 were compared by grouping based on clinical diagnosis,severity of ARDS,and clinical outcomes on day 28 after admission.The diagnostic and prognostic value of serum Lp-PLA2 in p-ARDS was evaluated by plotting the receiver operating characteristic(ROC)curve,Spearman correlation analysis,and Logistic regression analysis.Results The levels of serum Lp-PLA2 in the p-ARDS group([233.67±83.49]ng/mL)were significantly higher than that in the pneumonia group([150.86±39.48]ng/mL,P＜0.05),while those in the pneumonia group were significantly higher than that in the healthy control group([150.86±39.48]ng/mL vs[92.07±12.89]ng/mL,P＜0.05).The analysis results of the ROC curve showed that serum Lp-PLA2 had a better ability to distinguish p-ARDS from pneumonia than indicators such as IL-6,IL-8,CRP,and PCT,with an area under the ROC curve(AUCROC)of 0.781(95％CI:0.685-0.878).The diagnostic value of serum Lp-PLA2 combined with D-dimer was higher,with an AUCROC of 0.897(95％CI:0.832-0.963).Subgroup analysis found that as lung inju-ry worsened,the levels of serum Lp-PLA2 increased,and that serum Lp-PLA2 levels were negatively correlated with the PaO2/FiO2 ra-tio in p-ARDS patients(r=-0.549)and positively correlated with the sequential organ failure assessment(SOFA)scores at admission(r=0.412).The levels of serum Lp-PLA2 in the death group of p-ARDS were significantly higher than that in the survival group([314.5±43.1]ng/mL vs[174.9±48.9]ng/mL,P＜0.001).Logistic regression analysis showed that after adjusting for the SOFA score,serum Lp-PLA2 was independently associated with the mortality risk on day 28 after admission(OR=1.099,95％CI:1.026-1.178,P=0.007).Similar results were obtained after adjusting for IL-8 or the PaO2/FiO2 ratio.Conclusion Serum Lp-PLA2 may be used as a biomarker to aid in the diagnostic grading and prognostic assessment of p-ARDS.

【Objective】 To evaluate the effectiveness of Roche Cobas s 201 in detecting HBV by analyzing its blood nucleic acid testing (NAT) results. 【Methods】 The results were grouped according to the enzyme-linked immunosorbent assay (ELISA) and NAT minipool test (MP), NAT individual test (ID) and repeated NAT ID test (rID), and categorized into 4 groups as ELISA+ /NAT(ID)+ , ELISA+ /NAT(rID)+ , ELISA-/NAT(ID)+ and ELISA-/NAT(rID)+ . The data were statistically analyzed to explore whether there was a difference in the detection of reactive results by repeated NAT, and the correlation between cycle threshold (Ct) and nucleic acid detection rate for NAT-reactive samples with different ELISA results. The true infection status of blood donors was further analyzed by supplementary tests, including NAT systems and chemiluminescence serological marker assays using other methodologies. 【Results】 A total of 1 691 groups of 766 293 blood donor samples were HBV NAT(MP)+ , of which 1 418 groups(83.86%) were detected with reactive results (1 418 HBV NAT+ , 7 090 NAT-), and there were still 273 groups (16.14%) that remained undetected after repeated testing[a total of 1 638 NAT-, Ct(MP): 39.49±3.62]. Of the HBV NAT+ , 881(62.13%) were ELISA+ /NAT(ID)+ , 19(1.34%) were ELISA+ /NAT(rID)+ , 451(31.81%) were ELISA-/NAT(ID)+ , and 67(4.72%) were ELISA-/NAT(rID)+ . For samples with different ELISA results, difference was found in the detection of HBV by repeated NAT (P<0.05). There was no difference in Ct(ID) values between groups ELISA+ /NAT(rID)+ and ELISA-/ NAT(ID)+ , and groups ELISA+ /NAT(rID)+ and ELISA-/ NAT(rID)+ (P>0.05), but there were significant differences between other groups compared pairwise (P<0.05). Supplementary tests were performed on 228 ELISA-/ NAT(MP)+ (ID)- samples, 56 (24.56%) were reactive by chemiluminescent detection of HBsAg+ and 7 (3.07%) by other NAT systems. Among the remaining 221 NAT- samples/donors (96.93%), 53 (23.98%) HBsAg+ donors were likely to have chronic infection, 40 (18.10%) anti-HBe+ and/or anti-HBc+ donors might have previous infections, and the remaining 128 (57.92%) donors who were non-reactive were NAT (MP) pseudo-reactive, with significant differences in anti-HBs levels \'between groups (P<0.05). 【Conclusion】 Repeated NAT has differential detection of donor samples with different reactivity categories or different serologic results, especially within a certain interval, and repeated NAT for ELISA- samples can significantly improve the detection rate. Ct values can assist in assessing the stability and accuracy of the NAT system. For ELISA-/NAT(MP)+ (ID)- donors, the combination of other highly sensitive assays can reduce the risk of viral residuals and safeguard clinical blood safety.

Objective To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.
