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 assess the clinical value of prognostic nutritional index(PNI)in predicting the prognosis of patients with advanced liver cancer treated with transarterial chemoembolization(TACE)combined with ablation therapy.Methods A total of 112 patients with advanced liver cancer,who received TACE combined with ablation at the Lishui Municipal Central Hospital of China from January 2020 to January 2024,were enrolled in this study.The general data,survival status,and survival time were collected.The Youden index of PNI was calculated using the receiver operating characteristic(ROC)curve model,and the optimal cutoff value was determined.Based on the optimal cutoff value,the patients were divided into low-PNI group and high-PNI group.The progression-free survival(PFS)and overall survival(OS)time were compared between the two groups,and the independent risk factors affecting PFS and OS were analyzed.Results The Youden index for PNI was 0.43,and the optimal cutoff value of PNI was 43.95.The low-PNI group included 65 patients,and the high-PNI group included 47 patients.There were no statistically significant differences in the baseline data between the two groups.The median PFS and the median OS in the high-PNI group were 13.21 months(95％CI=4.37-22.03)and 40.80 months(95％CI=31.55-50.05)respectively,which were longer than 9.20 months(95％CI=6.58-11.82)and 21.37 months(95％CI=16.56-26.17)respectively in the low-PNI group,the differences were statistically significant(both P＜0.05).The 6-month,one-year and 2-year PFS in the high-PNI group was 56.95％,47.25％and 33.87％respectively,which were higher than 43.95％,32.56％and 16.31％respectively in the low-PNI group.The one-year,2-year and 3-year cumulative survival rates in the high-PNI group were 80.77％,66.66％and 39.40％respectively,which were higher than 63.79％,34.31％and 27.75％respectively in the low-PNI group.Multivariate regression analysis indicated that the number of nodules,metastasis and PNI significantly affected OS,and metastasis and PNI strikingly affected PFS.High PNI was a protective factor for both PFS and OS.Conclusion For patients with advanced liver cancer treated with TACE combined with ablation therapy,PNI is an effective indicator for predicting the prognosis.

Objective To evaluate the combination score of albumin-bilirubin index(ALBI)and alkaline phosphatase(ALP)in predicting the prognosis of patients with cirrhosis complicated by portal hypertension after receiving transjugular intrahepatic portosystemic shunt(TIPS).Methods A total of 61 patients with cirrhosis complicated by portal hypertension,who received TIPS treatment at the Lishui Municipal Central Hospital of China from January 2016 to June 2024,were retrospectively collected.According to the Youden index of ALBI and ALP,the optimal cut-off values were calculated,and the patients were divided into low ALBI-low ALP group(0-point group),high ALBI-high ALP group(2-point group),and high ALBI-low ALP or low ALBI-high ALP group(one-point group).The efficacy of ALBI-ALP score in predicting the prognosis of patients was evaluated,and the survival rate and median survival time were compared between each other among the three groups.The independent risk factors affecting the survival time of patients were analyzed.Results The maximum Youden indexes of ALBI and ALP were 0.31 and 0.34 respectively,and the optimal cut-off values were-1.56 and 108.50 respectively.There were statistically significant differences in MELD score,Child-Pugh classification,and alanine aminotransferase level between each other among the three groups(all P＜0.05).The area under the ROC curve(AUC)of ALBI-ALP score was 0.77(95％ CI:0.66-0.89,P=0.000 2),which was better than 0.52 of the MELD score(95％ CI:0.37-0.67,P=0.77)as well as better than 0.57 of the Child-Pugh classification(95％ CI:0.43-0.72,P=0.34).The total mortality of patients was 49.18％.The mortality in the 0-point group was 11.11％(2/18),which was significantly lower than 59.46％(22/37)in the one-point group as well as than 100％(6/6)in the 2-point group,and the differences were statistically significant(x2=18.20,P＜0.001).In the 0-point group,as a large number of patients were still alive at the end of the study,the median survival time was unable to be calculated.The median survival time in the one-point group was 38.00 months(95％ CI:23.01-52.99 months),which in the 2-point group was only 1.00 month(95％ CI=0.00-2.60 months),the difference was statistically significant(x2=33.08,P＜0.000 1).In the 0-point group,one-point group and 2-point group,the one-year survival rates were 100％,66％ and 17％respectively,the 2-year survival rates were 100％,64％ and 17％ respectively,and the 3-year survival rates were 90％,53％ and 0％ respectively.Cox multivariate regression analysis showed that the combination score of ALBI and ALP(HR=7.11,95％ CI:2.95-17.15)was an independent risk factor for the survival time of patients with cirrhosis complicated by portal hypertension after receiving TIPS.Conclusion The combination score of ALBI and ALP can effectively predict the prognosis of patients with cirrhosis complicated by portal hypertension after receiving TIPS,and this score is an independent risk factor affecting the survival time of patients.

Objective To observe the differences in gut microbiota in chronic unpredictable mild stress(CUMS)-induced depression model rats of both sexes,and to provide experimental evidence for exploring sex differences in depression onset.Methods Thirty-two healthy SD rats were divided randomly into four groups based on sex:Male control group(Control-M),Female control group(Control-F),Male model group(Model-M),and Female model group(Model-F)(n=8 rats per group).Rats in the control groups were fed without stimulation,while rats in the model groups were stimulated using the 28 d CUMS-induced depression method.After successful modeling,fresh feces were collected from all rats for high-throughput 16S rRNA sequencing.Behavioral observations were also conducted before and after preparing the model.Results The result of sucrose-preference,open-field,and forced-swimming tests differed significantly between the control and model groups.The result of the sucrose-preference test also differed between the sexes,while there was no difference in the open-field or forced-swimming test between the sexes.The α and β diversity of the gut microbiota genera showed an upward trend in the CUMS group compared with the control group.The ratio of Firmicutes/Bacteroidetes and the richness of the Roseburia and Lachnospiraceae_NK4A136_group were decreased in male rats but showed an increasing trend in female rats.Conclusions The ratio of Firmicutes/Bacteroidetes in the gut microbiota may be a key factor affecting the difference in the onset of depression between males and females,while the Roseburia and Lachnospiraceae_NK4A136_group be potential factors in correcting the gut microbiota and improving the symptoms of depression.

Objective:To analyze the medical service utilization preference of middle-aged and elderly residents (aged 45 and above) in Chongqing,and provide references for the local government to further promote the hierarchical diagnosis and improve the equity and efficiency of medical service utilization. Methods:Using a discrete choice experiment method,the preferences of 576 Chongqing residents,middle-aged and elderly,under conditions of mild and severe illness were measured for 6 attributes:medical service level,doctor's level,medical service mode,registration difficulty,drug supply and medical expenses. Results:Among patients with mild conditions,the attribute level most valued is"ability to register on the same day or the next day"(β=0.298,P<0.001) . They also prefer services from lower-level medical institutions and general practitioners (β=-0.200),as well as medical services with less cost (β=-0.003) . For patients with severe conditions,the attribute level they value the most is the medical service level (authoritative hospitals)(β=0.401,P<0.001),and they prefer services with ample drug supply (β=0.223),specialists (β=0.210),specialized departments (β=0.153),and higher costs (β=0.002) . The willingness to pay for patient shows an overall lower tendency for mild conditions and a higher one for severe conditions. Conclusion:Primary healthcare institutions have played a positive role in diverting patients,yet the tiered diagnosis and treatment system still requires ongoing improvement. Patients with mild conditions prefer convenient medical services,whereas those with severe conditions favor high-quality medical services. Under the burden of serious illness,medical expenses is a secondary factor influencing patients' choice of medical care. It is recommended to enhance the capacity and accessibility of high-quality medical resources,improving infrastructure and equipment at the primary level,expanding the availability of medications at these facilities,increasing the efficiency of specialist utilization,and strengthening the coordination among healthcare delivery,medical insurance,and pharmaceutical services—the"three-medicine linkage",address the difficulties and high costs of medical treatment experienced by the public,and achieve the goal of enabling residents to access affordable,high-quality health services locally.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

【Objective】 To observe the presence of ferroptosis in acute pancreatitis (AP) and the effect of iron ions on the NLRP3 pathway so as to explore the possible mechanisms for the protection of pancreatic alveolar cells. 【Methods】 A total of 45 male C57BL/6 mice were randomly divided into three groups (control, AP, and AP+2′2-bipyridyl). A total of 12 injections (caerulein, 50 μg/kg) were given at one-hour intervals. The AP+2′2-bipyridyl group was pretreated with 2′2-bipyridyl (20 mg/kg) for 1 hour, and then injected with caerulein. The control group was injected with an equal volume of normal saline. All of the mice were killed one hour after the last injection. Their pancreases were harvested for histopathological evaluation, immunohistochemistry analyses, and Western blotting. 【Results】 The ferroptosis inhibitor 2′2-bipyridyl could prevent the accumulation of iron ions, reduce the formation of lipid peroxides and the injury in the process of AP, and it also reduced pancreatic inflammation through NLRP3 pathway. 【Conclusion】 This experiment confirmed the real existence of ferroptosis, a form of cell death, in AP, and revealed that inhibition of ferroptosis can reduce pancreatic inflammatory damage in AP.

Objective:To investigate the effects of maternal subclinical hypothyroidism (SCH) on preschoolers′ behavioral problems.Methods:Based on the Ma′ anshan Birth Cohort, pregnant women who had their first antenatal checkup in Maternal and Child Health Center in Ma′ anshan were recruited from May 2013 to September 2014. Data on demographic, obstetric information, and maternal exposure were collected. Women′s fasting venous blood in the first, second, and third trimesters of pregnancy was collected. The levels of thyroid hormones [thyrotropin (TSH), free thyroxine (FT 4)] and thyroid autoantibodies [thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb)] in maternal blood were retrospectively detected by electrochemiluminescence immunoassay. Preschoolers′ behavioral problems were assessed by Achenbach Child Behavior Checklist (CBCL/1.5-5). Poisson regression models were adopted to examine the effect of maternal SCH on preschoolers′ internalizing and externalizing problems and the critical period. Results:In this study, the reference of maternal thyroid indexes was established (between 2.5 th and 97.5 th percentile). The reference of TSH in the first, second, and third trimester of pregnancy was 0.04-4.90 μIU/mL, 0.75-6.08 μIU/mL, and 0.58-5.59 μIU/mL respectively; and the reference of FT 4 was 13.19-23.27 pmol/L, 9.14-15.32 pmol/L, and 9.53-17.45 pmol/L respectively. In the first, second, and third trimester of pregnancy, the prevalence of SCH was found to be 2.0% (25/1 224), 1.6% (19/1 218), and 1.7% (21/1 220), respectively. After adjusting for confounding factors, maternal SCH in the first trimester was associated with the risk of anxiety and depression in preschool children ( OR=3.06, 95% CI 1.05-8.98). Maternal SCH in the second trimester was found to be associated with the risk of overreaction in preschool children ( OR=2.65, 95% CI 1.13-6.21). Conclusions:The establishment of thyroid hormones reference range for pregnant women in Ma′ anshan area is beneficial to the screening, diagnosis, and treatment of thyroid diseases during pregnancy in this area. Maternal SCH during pregnancy is associated with increased risk of behavioral problems in preschool children. In the first trimester, maternal SCH was associated with preschoolers′ anxiety and depression, and in the second trimester, maternal SCH was associated with preschoolers′ emotional reactivity.
