ObjectiveTo observe the prognosis effect of soluble programmed death ligand-1（sPD-L1） in treating patients with advanced lung adenocarcinoma treated with epidermal growth factor receptor-tyrosine kinase inhibitors（EGFR-TKIs） and the influence of Yiqi Yangyin Jiedu prescription. MethodA prospective cohort-controlled study was conducted to enroll patients treated with EGFR-TKIs in the first line of treatment，who were admitted to the Oncology Department of Longhua Hospital and Shanghai Chest Hospital from May 1^st， 2021 to June 30^th， 2023， and they were evaluated as non-progressive and identified with deficiency of Qi and Yin after one month of treatment. The patients were divided into an exposed group （EGFR-TKIs combined with Yiqi Yangyin Jiedu prescription） and a non-exposed group （EGFR-TKIs alone）according to whether or not they were treated with Yiqi Yangyin Jiedu prescription and were treated until disease progression， or death and intolerable adverse reactions occurred. The enzyme-linked immunosorbent assay （ELISA） was applied to detect the level of sPD-L1 in patients at the time of enrollment and disease progression，and Cox risk proportionality model was used to analyze the independent prognostic factors affecting disease progression of patients treated with EGFR-TKIs. ResultA total of 90 patients （39 in the exposed group and 51 in the non-exposed group） undergoing disease progression after EGFR-TKI treatment were enrolled. At the time of enrolment and after disease progression，the levels of serum sPD-L1 in the 90 patients were 12.06 （27.54） ng·L^-1 and 41.99 （62.93） ng·L^-1，respectively. Compared with that at the time of enrollment， the serum sPD-L1 level in the 90 patients was significantly increased after disease progression （P<0.01）. The serum sPD-L1 level in patients in the exposed group was 12.27 （24.78） ng·L^-1 and 29.57 （61.12）ng·L^-1 respectively at the time of enrolment and after disease progression. In the non-exposed group， patients had serum sPD-L1 levels of 11.81 （28.46） ng·L^-1 and 49.54 （74.12） ng·L^-1 respectively at the time of enrolment and after disease progression. Compared with that at the time of enrollment， the serum sPD-L1 level in the two groups of patients was significantly increased after disease progression （P<0.01）. In addition， compared with that in the non-exposed group， the sPD-L1 level in the exposed group was greatly reduced after disease progression（P<0.01）. Cox multifactorial analysis showed that sPD-L1 level and age at the time of enrolment were associated with patients' progression-free survival（PFS），and that low levels of sPD-L1 （<12.06 ng·L^-1） prolonged the PFS and reduced the risk of disease progression in patients treated with EGFR-TKIs compared with high levels of sPD-L1. ConclusionElevated sPD-L1 level is a poor prognostic factor for the long-term efficacy of EGFR-TKIs，and treatment with Yiqi Yangiin Jiedu prescription can down-regulate sPD-L1 level of patients treated with EGFR-TKIs.

OBJECTIVE To investigate the current status of pharmaceutical care in medical institutions in China， and provide experience and suggestions for better development of pharmaceutical care. METHODS Questionnaire survey was used to investigate the development of pharmaceutical care in medical institutions in 31 provinces （autonomous regions and municipalities directly） in March 2023， and descriptive analysis and binary logistic regression analysis on the influencing factors of pharmaceutical care were conducted. RESULTS A total of 1 368 questionnaires were sent out， and 1 304 valid questionnaires were collected with the effective recovery rate of 95.32%. Pharmaceutical care was carried out in 671 medical institutions （51.46%）， and the rates of pharmaceutical care in tertiary， secondary， primary and other medical institutions were 74.79%， 27.97% and 7.35%， respectively. The average number of patients receiving pharmaceutical care was 2 638.96 per year， and there were 8.33 pharmacists in each medical institution to carry out pharmaceutical care， among which 93.68% were clinical pharmacists. The main departments covered by pharmaceutical care services included respiratory and critical care medicine， cardiology， intensive care unit， endocrinology， oncology， gastroenterology， obstetrics and gynecology and other departments. There were only 48 medical institutions （7.15%） with additional compensation for pharmaceutical care services. The main experiences of developing pharmaceutical care were to pay attention to talent cultivation and discipline construction， but the main difficulties were serious shortage of staff and qualified talents， low compensation level and low enthusiasm. Grade of medical institutions， the number of pharmacists engaged in clinical pharmacy， the number of qualified clinical pharmacists and the degree of information in the pharmacy department were the main influencing factors for carrying out pharmaceutical care （P＜0.05）. CONCLUSIONS In recent years， pharmaceutical care in Chinese medical institutions has made certain progress， while that of primary medical institutions， secondary medical institutions and other medical institutions should be improved. In the future， it is still necessary to further enhance the implementation of pharmaceutical care， promote personnel training， and attach importance to demonstrating the value of pharmaceutical care， thereby promoting the sustainable and high- quality development of pharmaceutical care.

OBJECTIVE To analyze the components migrating to blood and metabolites of Polygonum cuspidatum in rats with acute gouty arthritis （AGA）. METHODS SD rats were randomly divided into blank group， model group and P. cuspidatum group （10 g/kg， by raw material）， with 6 rats in each group. Except for blank group， AGA model was induced in the remaining groups by injecting potassium oxonate and sodium urate； meanwhile， they were administered corresponding drug solutions or water intragastrically， once a day， for 10 consecutive days. The histopathological morphology of the knee joint tissues in rats was observed；rat serum samples were collected， and the components migrating to blood and metabolites of P. cuspidatum were analyzed by using UPLC-Q-Exactive-Orbitrap-MS. RESULTS Following the intervention with P. cuspidatum， the histopathological morphology of the knee joint synovial tissue in AGA rats showed significant improvement， with reduced inflammatory cell infiltration and hyperplasia， and the preservation of the honeycomb-like structure integrity. In both positive and negative ion modes， a total of 67 chemical components were detected in the serum of rats from P. cuspidatum group， including 25 prototype components and 42 metabolites. The involved compound types encompassed stilbenes， anthraquinones， naphthols， and flavonoids， among others. The metabolic reactions identified included methylation， acetylation， sulfation， and glucuronidation. Notably， compounds such as polydatin， resveratrol and emodin were capable of entering the bloodstream in their prototype forms and undergoing in vivo metabolism. CONCLUSIONS Compounds such as polydatin， resveratrol and emodin are likely to be the active components responsible for the anti-AGA effects of P. cuspidatum.

Poly(ADP-ribosyl)ation (PARylation) is a specific form of post-translational modification (PTM) predominantly triggered by the activation of poly-ADP-ribose polymerase 1 (PARP1). However, the role and mechanism of PARylation in the advancement of acute kidney injury (AKI) remain undetermined. Here, we demonstrated the significant upregulation of PARP1 and its associated PARylation in murine models of AKI, consistent with renal biopsy findings in patients with AKI. This elevation in PARP1 expression might be attributed to trimethylation of histone H3 lysine 4 (H3K4me3). Furthermore, a reduction in PARylation levels mitigated renal dysfunction in the AKI mouse models. Mechanistically, liquid chromatography-mass spectrometry indicated that PARylation mainly occurred in receptor for activated C kinase 1 (RACK1), thereby facilitating its subsequent phosphorylation. Moreover, the phosphorylation of RACK1 enhanced its dimerization and accelerated the ubiquitination-mediated hypoxia inducible factor-1α (HIF-1α) degradation, thereby exacerbating kidney injury. Additionally, we identified a PARP1 proteolysis-targeting chimera (PROTAC), A19, as a PARP1 degrader that demonstrated superior protective effects against renal injury compared with PJ34, a previously identified PARP1 inhibitor. Collectively, both genetic and drug-based inhibition of PARylation mitigated kidney injury, indicating that the PARylated RACK1/HIF-1α axis could be a promising therapeutic target for AKI treatment.

Objective:To analyze the clinicopathological features and differential diagnosis of large B-cell lymphoma with IRF4 rearrangement, aiming enhance its recognition and prevent misdiagnosis.Methods:The clinicopathological features, immunophenotype, and fluorescence in situ hybridization (FISH) results of six cases diagnosed with IRF4 rearrangement-positive B-cell lymphoma at the Affiliated Hospital of Xuzhou Medical University from 2015 to 2023 were retrospectively analyzed. Additionally, a comprehensive review of the literature was conducted.Results:Six patients with IRF4 rearrangement-positive large B-cell lymphoma were included. Patients 1 to 5 included three males and two females with a median age of 19 years ranging from 11 to 34 years. Four patients presented with head and neck lesions, while the other one had a breast nodule; all were in clinical Ann Arbor stages I to Ⅱ. Morphologically, entirely diffuse pattern was present in two cases, purely follicular pattern in one case, and diffuse and follicular patterns in other two cases. The tumor cells, predominantly centroblasts mixed with some irregular centrocytes, were of medium to large size, with a starry sky appearance observed in two cases. Immunophenotyping revealed all cases were positive for bcl-6 and MUM1, with a Ki-67 index ranging from 70% to 90%, and CD10 was positive in two cases. IRF4 rearrangement was confirmed in all cases by FISH analysis, with dual IRF4/bcl-6 rearrangements identified in two cases, leading to a diagnosis of LBCL-IRF4. Case 6, a 39-year-old female with a tonsillar mass and classified as clinical Ann Arbor stage Ⅳ, displayed predominantly diffuse large B-cell lymphoma (DLBCL) morphology with 20% high-grade follicular lymphoma characteristics. Immunohistochemistry showed negative CD10 and positive bcl-6/MUM1, with a Ki-67 index of approximately 80%. Triple rearrangements of IRF4/bcl-2/bcl-6 were identified by FISH, leading to a diagnosis of DLBCL with 20% follicular lymphoma (FL). All six patients achieved complete remission after treatment, with no progression or relapse during a follow-up period of 31-100 months.Conclusions:Large B-cell lymphoma with IRF4 rearrangement is a rare entity with pathological features that overlap with those of FL and DLBCL. While IRF4 rearrangement is necessary for diagnosing LBCL-IRF4, it is not specific and requires differentiation from other aggressive B-cell lymphomas with IRF4 rearrangement.

OBJECTIVE To investigate the basic situation of developing pharmacy outpatient departments in Chinese tertiary medical institutions and analyze the influencing factors. METHODS The research targeted the pharmacy outpatient department managers of hospitals and conducted a survey through Sojump in March 2023. Various independent variables were selected from the hospital’s own characteristics， the management of the pharmacy outpatient departments， and the construction of the pharmacist team for Logistic and linear regression analysis， with the aim of separately analyzing the factors influencing the establishment of pharmacy outpatient departments and the factors affecting the total number of patients served by these departments throughout the year 2022. RESULTS & CONCLUSIONS A total of 1 304 medical institutions of different levels nationwide participated in this survey， with 714 tertiary hospitals. Among the tertiary hospitals， 377 （52.80%） had established pharmacy outpatient departments， including 321 grade-A tertiary hospitals， 48 grade-B tertiary hospitals and 8 other tertiary hospitals. The 377 tertiary hospitals collectively operated 1 739 pharmacy outpatient departments， covering 19 specialized fields， with the highest proportion found in the cardiovascular field （including anticoagulation） at 16.45%. Tertiary hospitals in North China， Central China， East China and South China regions had more pharmacy outpatient departments. The establishment of pharmacy outpatient departments was found to be influenced by tertiary grade-B status （P＝0.010） and the annual outpatient volume of the hospital （P＝0.008）， although the impact was relatively small. The factors influencing the number of patients served by pharmacy outpatient departments were the annual outpatient volume of the hospital （P＝0.042） and the number of pharmacists engaged in clinical pharmacy work （P＝0.004）. The proportion of tertiary hospitals in China that have established pharmacy outpatient departments is insufficient. It is necessary to further accelerate the construction of pharmacy outpatient departments and appropriately expand the talent pool of hospital pharmacy teams based on the needs of pharmacy outpatient departments and patients， in order to meet the requirements of medical practice and patient care.

OBJECTIVE To investigate the current situation of pharmaceutical clinic service in medical institutions in China and provide experience and suggestions for promoting the development of pharmaceutical clinics. METHODS Questionnaire survey was used to investigate the development of pharmaceutical clinics in medical institutions of 31 provinces （autonomous regions and municipalities directly under the central government） in March to April 2023， and the descriptive analysis was conducted. The regression analysis was carried out for the influential factors of pharmaceutical clinic service. RESULTS A total of 1 368 questionnaires were distributed in this survey and 1 304 valid questionnaires were collected with the effective response rate of 95.32%. A total of 463 medical institutions carried out pharmaceutical clinic service， the rate of which was 35.51% （463/1 304）； the rates of pharmaceutical clinics in tertiary， secondary， primary and other medical institutions were 52.80%， 17.18% and 5.88%， respectively. The frequency of opening pharmaceutical clinics was 3.17 days per week on average， with an average of 5.99 visiting pharmacists in each medical institution. Among the visiting pharmacists， clinical pharmacists accounted for the vast majority （88.68%， 2 459/2 773）. There were various categories of pharmaceutical clinics， including joint clinics and pharmacist-independent clinics； among pharmacist-independent clinics， pharmaceutical specialty/specialty disease clinics were the main ones， accounting for 89.72% of the total number of pharmaceutical clinics. The value of pharmacists in pharmaceutical clinics was manifested in various forms， among which the proportion of medical institutions charging pharmaceutical clinics was 10.80%. The main experiences in developing pharmaceutical clinics were to attach importance to discipline construction and personnel training. The main difficulties in developing pharmaceutical clinics were low compensation levels and a shortage of talent.The number of clinical pharmacists， the number of visiting pharmacists in pharmaceutical clinics and additional compensation were positively correlated with the amount of pharmaceutical clinic services（P＜0.05）. CONCLUSIONS In recent years， pharmaceutical clinics have made significant progress； in the future， it is still necessary to further strengthen discipline construction and talent cultivation， pay attention to the value embodiment of pharmacists， to promote the healthy development of pharmaceutical clinics.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Objective To analyze the characteristics of platelet changes and their influencing factors during postoperative hospitalization in patients who underwent transcatheter aortic valve implantation (TAVI). Methods The patients who underwent TAVI at Beijing Anzhen Hospital Valve Surgery Center between March 2017 and October 2021 were retrospectively selected. The patients were divided into a self-limiting group and a non-self-limiting group according to the characteristics of postoperative platelet decline. In addition, the general preoperative data, preoperative and postoperative ultrasound data, intraoperative data, and the use of anticoagulant drugs during the postoperative stay in the hospital were compared between the two groups. Results A total of 249 patients were enrolled in this study. There were 175 (70.3%) patients in the self-limiting group, including 100 males and 75 females, and there were 74 (29.7%) patients in the non-self-limiting group, including 43 males and 31 females, with no statistical difference between the two groups (P=0.863). The mean age of patients was 73.11±8.88 years in the self-limiting group and 71.54±10.39 years in the non-self-limiting group (P=0.231). The decline of platelets in the self-limiting group generally occurred on the postoperative day 2 and reached the lowest count on the postoperative day 4, and returned to the baseline level on the postoperative day 5-7, while the platelets in the non-self-limiting group changed by simple rise, fall or irregular fluctuation. Patients in the self-limiting group had severer preoperative aortic stenosis (P<0.001) and used more extracorporeal circulation assistance during surgery (P<0.001). Postoperatively, patients in the self-limiting group were more likely to have periaortic valve leakage than those in the non-self-limiting group (P=0.013). Conclusion Platelet changes in most patients after TAVI show a self-limiting decline, which may be related to the severity of patients’ preoperative aortic stenosis, intraoperative extracorporeal circulation device use, and postoperative perivalvular leakage.
