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 levels and influencing factors for eye lens dose of interventional radiology workers, and to provide a basis for reasonable and scientific radiation protection. Methods Thermoluminescent eye lens dosimeters were used to monitor the left and right eye lens doses of interventional radiology workers in real time during different surgical positions and varying eye protection conditions. The annual eye lens doses for the operators were estimated based on their yearly workload. The differences in eye lens doses under different conditions were analyzed and the influencing factors were identified. Results For individual interventional operations, the range of personal dose equivalent H_p(3) of the left eye of interventional radiology workers was ( < MDL ~ 418.33) μSv, the median (Q₁, Q₃) was 9.29 ( < MDL, 40.79) μSv, and the mean was 40.79 ± 70.36 μSv. The estimated annual eye lens doses were 4.05 mSv and 17.80 mSv based on the median and mean values of the eye lens dose of a single operation multiplied by average annual frequency of operations per person, respectively. The left eye lens dose was higher than the right eye lens dose of the same operator (Z = −4.24, P < 0.05), and the dose of the right eye lens was strongly positively correlated with that of the left eye lens. The left eye lens dose of the first surgeon was higher than that of the second surgeon in the same operation (Z = −3.10, P < 0.05). The eye lens dose was influenced by operator position (χ² = 9.149, P = 0.002, OR = 8.343), eye protection (χ² = 4.619, P = 0.032, OR = 4.352), and air kerma area product (χ² = 8.032, P = 0.005, OR = 5.488). Conclusion According to the results of this study, a significant portion of interventional operators have eye lens doses that approach or exceed international occupational dose limits. It is recommended to pay attention to the operation frequency of the first operator and the air kerma area product of interventional operation, and strengthen radiation protection and dose monitoring for the eye lens of interventional radiology workers.

ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang （BWT） on non-alcoholic fatty liver disease （NAFLD） and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups： normal control， model， positive drug （pioglitazone hydrochloride 1.95×10^-3 g·kg^-1）， and low-， medium-， and high-dose BWT （1.3，2.5 and 5.1 g·kg^-1）. Following a 12-week high-fat diet （HFD） inducement， the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week， glucose tolerance （GTT） and insulin tolerance （ITT） tests were conducted. Subsequently， the mice were euthanized for the collection of liver tissue and serum， and the subcutaneous adipose tissue （iWAT） and epididymal adipose tissue （eWAT） were weighed. Serum levels of total triglycerides （TG） and liver function indicators，such as alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， were determined. Histological examinations， including oil red O staining， hematoxylin-eosin （HE） staining， Masson staining， and transmission electron microscopy， were performed to evaluate hepatic lipid deposition， pathological morphology， and ultrastructural changes， respectively. Meanwhile， Western blot and real-time quantitative polymerase chain reaction （Real-time PCR） were employed to analyze alterations， at both gene and protein levels， the insulin signaling pathway molecules， including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 （IRS1/2/Akt/FoxO1）， glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase （Pepck） and glucose-6-phosphatase （G6Pase）， lipid metabolism-related genes stearoyl-coA desaturase-1 （SCD-1） and carnitine palmitoyltransferase-1 （CPT-1）， fibrosis-associated molecules α-smooth muscle actin （α-SMA）， type Ⅰ collagen （CollagenⅠ）， and the fibrosis canonical signaling pathway transforming growth factor-β₁/drosophila mothers against decapentaplegic protein2/3（TGF-β₁/p-Smad/Smad2/3）， inflammatory factors such as interleukin（IL）-6， IL-8， IL-11， and IL-1β， autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1， and the expression of mammalian target of rapamycin （mTOR）. ResultCompared with the model group， BWT reduced the body weight and liver weight of NAFLD mice（P<0.05， P<0.01）， inhibited liver lipid accumulation， and reduced the weight of white fat： it reduced the weight of eWAT and iWAT（P<0.05， P<0.01） as well as the serum TG content（P<0.05， P<0.01）. BWT improved the liver function as reflected by the reduced ALT and AST content（P<0.05， P<0.01）. It improved liver insulin resistance by upregulating IRS2， p-Akt/Akt， p-FoxO1/FoxO1 expressions（P<0.05）. Besides， it improved glucose and lipid metabolism disorders： it reduced fasting blood glucose and postprandial blood glucose（P<0.05， P<0.01）， improved GTT and ITT（P<0.05， P<0.01）， reduced the expression of Pepck， G6Pase， and SCD-1（P<0.01）， and increased the expression of CPT-1（P<0.01）. The expressions of α-SMA， Collagen1， and TGF-β₁ proteins were down-regulated（P<0.05， P<0.01）， while the expression of p-Smad/Smad2/3 was downregulated（P<0.05）， suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6， IL-8， IL-11 and IL-1β（P<0.01） and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression（P<0.05）while downregulating the expression of p62/SQSTM1 and mTOR（P<0.05）. ConclusionBWT ameliorates NAFLD by multifaceted improvements， including improving IR and glucose and lipid metabolism， anti-inflammation， anti-fibrosis， and enhancing autophagy. In particular， BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

Objective:To explore the risk factors of all-cause death in hypertensive patients in the community.Methods:A cohort of 4 049 hypertensive patients who participated in annual health checkups at Xinzhuang Community Health Service Centre of Shanghai Minhang district from January to December 2012 were enrolled in the study. All-cause death was the endpoint event of this study, and patients were divided into a fatal group and a survival group. The collection date for the endpoint event was December 2022. A multivariate Cox regression model was used to analyse the independent risk factors of all-cause mortality among hypertensive patients in the community.Results:Among 4 049 patients aged (67.9±7.1) years, 1 856 (45.8%) were males. There were 610 cases in the fatal group and 3 439 cases in the survival group. Multivariate Cox proportional regression showed that male gender ( HR=1.446, 95% CI: 1.200-1.742, P<0.001), older age ( HR=1.130, 95% CI: 1.118-1.143, P<0.001), higher waist-to-height ratio ( HR=8.117, 95% CI: 2.235-29.481, P=0.001), positive urinary protein ( HR=2.974, 95% CI: 2.202-4.016, P<0.001), high fasting blood glucose ( HR=1.070, 95% CI: 1.012-1.131, P=0.017), and history of stroke ( HR=1.819, 95% CI: 1.414-2.340, P<0.001) were independent risk factors for all-cause mortality in hypertensive patients, while exercise≥1/week ( HR=0.816, 95% CI: 0.668-0.996, P=0.046) and taking lipid-lowering medications ( HR=0.459, 95% CI: 0.223-0.947, P=0.035) were protective factors for all-cause mortality. Conclusion:For hypertensive patients, male gender, older age, higher waist-to-height ratio, positive urinary protein, high fasting blood glucose, and history of stroke are risk factors for all-cause mortality, while exercise≥1/week and taking lipid-lowering medications are protective factors.

Objective:To analyze the association between sleep status and ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.Methods:It was a cross sentional study. Hypertensive patients who underwent 24-hour ambulatory blood pressure monitoring from May 2021 to April 2023 in Shanghai Xinzhuang Town were enrolled. The demographic information and sleep status of patients were obtained from the questionnaire. A TM-2430 blood pressure monitor was used to measure 24-hour ambulatory blood pressure, and the relevant indicators, including blood pressure level and blood pressure coefficient of variation were documented. The association between sleep status and blood pressure indicators was analyzed with multivariate linear regression model.Results:A total 1 135 patients aged (65.07±12.61) years were enrolled, and 473 (41.67%) of whom were males. The sleep time was<7 hours in 76 cases, 7- 8 hours in 219 cases and >8 hours in 840 cases; the bedtime was earlier than 22∶00 in 415 cases, between 22∶00 and 23∶00 in 474 cases and later than 23∶00 in 246 cases; the wake-up time was before 6∶00 in 230 cases, between 6∶00 and 7∶00 in 521 cases and after 7∶00 in 384 cases. Multivariate linear regression analysis showed that after controlling for gender and age, the sleep time was negatively associated with diurnal, noctumal and 24-hour diastolic blood pressure levels (all P<0.05), and positively associated with diurnal and noctumal systolic blood pressure coefficient of variation, noctumal diastolic blood pressure coefficient of variation, and 24-hour systolic blood pressure coefficient of variation (all P<0.05).The bedtime was positively associated with diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), diastolic blood pressure (all P<0.05); and negatively associated with diurnal systolic blood pressure coefficient of variation, diurnal diastolic blood pressure coefficient of variation, noctumal systolic blood pressure coefficient of variation, 24-hour systolic blood pressure coefficient of variation, and 24-hour diastolic blood pressure coefficient of variation (all P<0.05). The wake-up time was positively associated with diurnal systolic blood pressure, diurnal, noctumal and 24-hour diastolic blood pressure (all P<0.05), and positively associated with diurmal systolic blood pressure and diastolic blood pressure (both P<0.05). Conclusion:Sleep status is closely associated with ambulatory blood pressure monitoring indicators in community-dwelling hypertensive patients.

OX40 is a costimulatory receptor that is expressed primarily on activated CD4⁺, CD8⁺, and regulatory T cells. The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion, differentiation, and activation and also promotes dendritic cells to mature to enhance their cytokine production. Therefore, the use of agonistic anti-OX40 antibodies for cancer immunotherapy has gained great interest. However, most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy. Here, we discovered that BGB-A445, a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation, induced optimal T cell activation without impairing dendritic cell function. In addition, BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity. In the MC38 syngeneic model established in humanized OX40 knock-in mice, BGB-A445 demonstrated robust and dose-dependent antitumor efficacy, whereas the ligand-competitive anti-OX40 antibody showed antitumor efficacy characterized by a hook effect. Furthermore, BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody. Taken together, our findings show that BGB-A445, which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies, shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation.

Objective:To investigate the interaction of B-group streptococcal infection and chorioamnionitis (CAM) with late pregnancy and low birth weight infant (LBWI).Methods:A retrospective study was conducted on 524 postpartum women who underwent regular prenatal examinations and completed delivery at the Taizhou Second People′s Hospital from October 2019 to April 2022. According to their newborn birth weight, they were divided into normal group (466 cases) and LBWI group (58 cases). The age, pregnancy times, birth times, pregnancy body mass index (BMI), cesarean section history, abortion history, anemia during pregnancy, hypertensive disorder during pregnancy, diabetes during pregnancy, vaginitis, B-group streptococcal infection, CAM, premature rupture of membranes, postpartum hemorrhage, puerperal infection, neonatal preterm delivery, neonatal asphyxia, neonatal infection, fetal distress were compared between the two groups. The influencing factors of LBWI were analyzed using logistic regression. The correlation and interaction between B-group streptococcal infection and CAM on LBWI were analyzed.Results:There was a statistically significant difference in age, history of miscarriage, gestational hypertension, vaginitis, B-group streptococcal infection, CAM, premature rupture of membranes, neonatal preterm birth, neonatal infection and fetal distress between the two groups (all P<0.05). The results of logistic regression analysis showed that gestational hypertension, B-group streptococcal infection, CAM, premature rupture of membranes, preterm birth, neonatal infection, and fetal distress were risk factors for LBWI (all P<0.05). B-group streptococcal infection, CAM, and LBWI were positively correlated ( r=0.587, 0.604, all P<0.001). The interaction analysis results showed a positive correlation between B-group streptococcal infection, CAM, and LBWI (all P<0.001). Conclusions:B-group streptococcal infection in late pregnancy, CAM, and LBWI are positively correlated, and their coexistence can increase the risk of LBWI.

Objective:To study the application value of flipped classroom teaching mode in clinical teaching of gynecological operating room.Methods:A total of 146 cases of gynecological operating room intern nursing students in The People's Hospital of Liaoning Province from January 2020 to April 2020 were selected as the research objects and divided into two groups according to different time. Before the flipped classroom teaching mode was carried out from January 2020 to February 2020, 73 cases were included in the control group, and after the flipped classroom teaching mode was carried out from March 2020 to April 2020, 73 cases were included in the observation group. The theory and operation scores of the two groups before and after teaching were compared, and the satisfaction of the practice nurses to the teaching and the evaluation of the observation group to the flipped classroom teaching mode were observed. After the teaching, the performances of the two groups of nursing students and the teaching satisfaction were compared using SPSS 22.0 to conduct t test, chi-square test and rank sum test. Results:The theoretical results[(88.52±8.99) points] and operational results[(89.79±7.51) points] of the observation group were significantly higher than those[(72.40±7.45) points and (73.66±7.77) points] of the control group, with statistical significance ( P<0.05). The teaching methods and self-evaluation satisfaction of the observation group were significantly higher than those of the control group ( P<0.05). Conclusion:The application of flipped classroom teaching mode in the teaching of nursing students in gynecological operating room can improve the students' operation and theoretical level, and the students have a high degree of recognition and satisfaction with the teaching mode.

【Objective】 To explore the quantitative value of key points for ABO blood group initial screening in fixed blood donation sites, so as to provide reference for standardized testing process of sliding method. 【Methods】 Several groups of experiments were carried out to illustrate the optimal conditions, including the serum dosage of monoclonal reagent, red blood cell dosage of blood sample, and reaction time in ABO blood group initial screening, by sliding method, and the quantitative value of key points of sliding method was preliminarily determined. Blood typing tests of 310 blood donor samples including type A, B, O, AB, subtype A and subtype AB were conducted to evaluate the effects of quantitative value of key points in the initial screening procedure. The test tube method would be conducted if the results are inconsistent with the fully automated blood grouping analyzer. The ABO subtypes suspected are identified by serological and molecular biological methods. 【Results】 The quantitative value of key points in initial screening procedure of sliding methods was as follows: 2 drops of reagent serum, 5-10 μL of whole blood and 3 minutes of reaction time. The concordance rate of ABO blood type screening comparison experiment in 310 blood donors was 100%. 【Conclusion】 ABO blood group initial screening by sliding method with quantitative value can effectively standardize the pre-donation blood type screening in fixed blood donation sites, and can meet the requirements of ABO blood group initial screening.

Objective:To explore the influence of selective fetoscopic laser occlusion of chorioangiopagous vessels (FLOC) versus Solomon surgery in the management of twin-to-twin transfusion syndrome (TTTS) on procedure-related complications, fetal survival rate, and residual anastomoses.Methods:A total of 59 pregnant women with TTTS who underwent FLOC in the Third Affiliated Hospital of Zhengzhou University from May 2018 to March 2020 were retrospectively enrolled and divided into Solomon ( n=33) and selective FLOC groups ( n=26) based on the FLOC operation method. Placentae of 25 pregnant women (15 in the Solomon group, 10 in the selective FLOC group) with both survival twins were perfused to observe the type and diameter of the residual anastomoses. Fetal survival rate, procedure-related complications, and the type and diameter of residual anastomoses were analyzed and compared between the two groups using two independent samples t-test, Mann-Whitney U test, χ2 test and Fisher's exact test. Results:(1) The operating time of Solomon was shorter than that of selective FLOC [74 min (60-90 min) vs 95 min (81-123 min), Z=2.906, P=0.004]. But no statistically significant differences in the gestational week at operation, time of pregnancy end, and the interval between operation and pregnancy end was observed between the two groups (all P>0.05). (2) There was no statistically significant difference in the survival rate of both twins, one fetus, at least one fetus, and the incidence of postoperative twin anemia-polycythemia sequence (TAPS) and recurrent TTTS in the Solomon group and selective FLOC group [64%(21/33) vs 50%(13/26), χ2=1.107; 15%(5/33) vs 35%(9/26), χ2=3.044; 79%(26/33) vs 85%(22/26), χ2=0.326; 3%(1/33) vs 12%(3/26), χ2=1.368; 0% (0/33) vs 4%(1/26), χ2=1.118; all P>0.05]. (3) There was no statistically significant difference in the number of placentae with residual anastomoses or the number of artery-to-vein, vein-to-artery, artery-to-artery, and vein-to-vein anastomoses between the two groups (7/15 vs 6/10, 2/8 vs 4/15, 3/8 vs 4/15, 2/8 vs 5/15, 1/8 vs 2/15; Fisher's exact test, all P>0.05), but the diameter of the residual anastomoses in the Solomon group was smaller than that in the selective FLOC group [(0.8±0.3) and (2.2±0.7) mm, t=0.764, P=0.034]. (4) Among the four pregnant women developed TAPS after operation, one patient had two residual artery-to-vein anastomoses in the placenta with diameter of 0.54 mm and 0.43 mm, respectively; one patient had one artery-to-vein anastomosis with a diameter of 0.64 mm; one had one artery-to-artery and one vein-to-vein anastomosis with diameter of 1.56 mm and 1.89 mm, respectively. Conclusions:Compared with selective FLOC, Solomon surgery can reduce the vessel diameter of residual anastomoses in women with TTTS, but does not reduce postoperative complications, nor improve the pregnancy outcomes.
