OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

Objective:To investigate the different clinical characteristics and prognosis of patients with diabetic nephropathy (DN) accompanied by IgA deposition diagnosed by renal biopsy.Methods:The study was a retrospective cohort study. Clinical and pathological data of patients diagnosed with DN through renal biopsy in Beijing Anzhen Hospital affiliated to Capital Medical University from January 1, 2010 to March 31, 2023 were retrospectively collected. The clinical and pathological characteristics and prognosis of DN patients with IgA deposition and DN control group patients without IgA deposition were compared. Immunofluorescence staining was used to detect the intensity of galactose-deficient IgA1 (Gd-IgA1) staining in renal tissue of DN patients with DN IgA deposition, and grouping was performed according to whether the staining intensity was≥2+. Enzyme linked immunosorbent assay was used to detect the serum level of Gd-IgA1 in patients. A 50% decrease in estimated glomerular filtration rate (eGFR) from baseline or progression to end-stage renal disease within 5 years was defined as a renal endpoint event, and Kaplan-Meier survival analysis and Log-rank test were used to compare the difference in cumulative incidence of renal endpoint events between two groups of patients.Results:A total of 101 DN patients were enrolled in this study, including 68 males (67.3%) and 33 females (32.7%), with age of (52.2±10.3) years and a median follow-up time of 13.5(4.8, 26.3) months. There were 44 patients with IgA deposition (43.6%) and 57 patients without IgA deposition (56.4%). Compared with DN control group, Kaplan-Meier analysis showed that DN patients with IgA deposition had a higher cumulative incidence of renal endpoint within 5 years ( χ2=6.473, P=0.011). The proportion of positive glomerular Gd-IgA1 (KM55) staining in the DN patients with IgA deposition was 54.5% (24/44), and immunofluorescence examination showed consistent distribution of Gd-IgA1 and IgA in the glomerular mesangial and capillary regions. The serum level of Gd-IgA1 in the glomerular Gd-IgA1 positive patients was significantly higher than that in those negative patients [(6 296.4± 1 535.4) μg/L vs. (4 057.4±1 082.0) μg/L, t=-3.037, P=0.010]. In DN patients with IgA deposition, the age of the subgroup with endpoint events was younger [(42.8±6.9) years vs. (53.3±9.4) years, t=-3.440, P=0.002], the duration of proteinuria was shorter [6.0(1.0, 22.0) months vs. 12.0(10.0, 36.0) months, Z=-2.150, P=0.032], and the proportion of patients with glomerular Gd-IgA1 staining intensity ≥2+ was higher [Fisher'exact test, 30.8%(4/13) vs. 0(0/20), P=0.017]. Kaplan-Meier survival analysis showed that patients with glomerular Gd-IgA1 staining intensity≥2+ had a significantly higher cumulative incidence of renal endpoint events ( χ2=4.846, P=0.028). Conclusion:DN patients with glomerular IgA deposition and Gd-IgA1 positivity may be associated with worse prognosis.

Objective:To investigate the correlation between serum growth differentiation factor 15 (GDF15) and the clinicopathological characteristics of patients with IgA nephropathy (IgAN), and further explore the relationship of GDF15 with the cardiac and renal prognosis of IgAN patients.Methods:It was a single-center retrospective cohort study. From January 2018 to December 2022, the relevant data were collected from patients who were diagnosed with primary IgAN at the Department of Nephrology, Beijing Anzhen Hospital Affiliated to Capital Medical University, and regularly followed up for at least 1 year. Serum samples were collected at admission and the baseline level of serum GDF15 was measured. Based on the median GDF15 level, IgAN patients were categorized into high-level GDF15 group and low-level GDF15 group, and their clinicopathological characteristics were compared. A multiple linear regression model was then constructed to identify independent factors associated with serum GDF15 level based on these comparisons. Subsequently, Kaplan-Meier survival analysis was performed to investigate the association between serum GDF15 level and the cardiorenal prognosis of IgAN patients.Results:A total of 104 IgAN patients were included in this study. The serum GDF15 level in these IgAN patients was 825.60 (556.84, 1 428.15) ng/L. Serum GDF15 level was positively correlated with 24 h urinary protein ( r=0.405, P<0.001), negatively correlated with estimated glomerular filtration rate (eGFR)( r=-0.606, P<0.001). The serum levels of GDF15 in patients with tubular atrophy or interstitial fibrosis (overall comparison among T0, T1, and T2, H=21.866, P<0.001), crescentic lesions (overall comparison among C0, C1, and C2, H=13.787, P=0.001), or intrarenal arteriolar lesions (overall comparison among none, mild, and moderate-to-severe, H=9.856, P=0.007) were significantly different. Compared with IgAN patients without tubular atrophy or interstitial fibrosis, those with Oxford classification T1 ( Z=-17.326, P=0.042) or T2 ( Z=-42.933, P<0.001) had higher serum GDF15 levels. Compared with IgAN patients without crescentic lesions, those with Oxford classification C2 had higher serum GDF15 levels ( Z=-45.929, P=0.001). Compared with IgAN patients without intrarenal arteriolar lesions, those with moderate-to-severe arteriolar sclerosis had higher serum GDF15 levels ( Z=-26.686, P=0.005). The median GDF15 was used as the cut-off value to divide IgAN patients into a high-level GDF15 group (≥825.60 ng/L, n=52) and a low-level GDF15 group (<825.60 ng/L, n=52). Compared to low-level GDF15 group, IgAN patients in high-level GDF15 group presented with a higher proportion of diabetes mellitus ( χ 2=9.420, P=0.002) and cardiovascular disease ( χ 2=7.792, P=0.005), a higher level of systolic blood pressure ( Z=-2.266, P=0.023), body mass index ( Z=-2.183, P=0.031), 24 h urinary protein ( Z=-3.485, P<0.001), blood total cholesterol ( Z=-2.002, P=0.045) and left ventricular mass index ( Z=-2.649, P=0.008), and a lower level of blood albumin ( Z=-3.053, P=0.002) and eGFR ( Z=6.480, P<0.001). Multiple linear regression analysis showed that serum GDF15 level was independently associated with systolic blood pressure (regression coefficient B=29.453, 95% CI 14.139–44.767, P<0.001), blood albumin ( B=-81.412, 95% CI -113.084–-49.740, P<0.001) and eGFR ( B=-9.797, 95% CI -17.554–-2.040, P=0.014). Moreover, IgAN patients in high-level GDF15 group exhibited significantly poorer cardiac and renal prognosis compared to low-level GDF15 group ( χ 2=9.955, P=0.002). Conclusion:High serum GDF15 level correlates with disease severity in IgAN, and high serum GDF15 level may suggest a poorer cardiorenal prognosis in IgAN patients.

Objective To conduct Rh blood group serological testing and third-generation sequencing(TGS)on 22 RhD variant voluntary blood donors in Chongqing and explore the phenotypic distribution and genotyping of RhD variants in Chongqing.Methods From January to August 2023,individuals who participated in blood donation in our blood center were selected as the study objects.RhD variant phenotype identification was performed using routine serological methods.Once the RhD variants were identified,tests on different antigenic epitopes of RhD were conducted using a D-screen assay kit.Furthermore,after the genomic DNA from 22 RhD variant blood samples was extracted,imbraided primers design and multi-segment amplification and splicing were used to sequence the full-length RHD gene for TGS.The RHD gene sequence was analyzed using SnapGene software.Results Among the 22 RhD variants,8 were DVI type 3(36.36%),with the main mutation of RHD-CE(3-6)-D hybrid allele.Six cases(27.27%)showed partial weak D15 type,with the main mutation of c.845G>A.There were 6 cases of Asia type Del(27.27%),with the main mutation of c.1227G>A.One case was weak D17 type with a mutation of c.340C>T and 1 case speculated to be partial D(c.491A>T,p.Asp164Val,missense mutation).Conclusion The most common RhD variant phenotype among blood donors in Chongqing is DVI type 3,and the full-length haplotype sequence of RHD variant alleles can be obtained by Pacific Bioscience single-molecule real-time sequencing(SMRT).

OBJECTIVE To calculate the cost of centralized dispensing of four categories of drugs （ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions） in pharmacy intravenous admixture service （PIVAS）， and provide reference for setting charging standards for relevant departments. METHODS The operating costs of PIVAS in 12 medical institutions from Shaanxi province were collected through questionnaire survey， including labor costs， medical and health material costs， fixed asset depreciation and repair costs， water and electricity costs， and management costs. The operation time allocation coefficient method and workload allocation coefficient method were comprehensively used to allocate the above costs， and the unit preparation costs of four categories of drugs were calculated. RESULTS The average annual total costs of dispensing ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions in Shaanxi province were （2 195 900.25±1 680 893.73） yuan， （746 341.59±725 839.39） yuan， （331 420.15±183 258.83） yuan， and （330 322.68±277 281.70） yuan， respectively， with labor costs accounting for the highest proportion， averaging 85.49%. The costs of dispensing a set of ordinary drugs， antibacterial drugs， and hazardous drugs were 5.89， 7.60， and 14.37 yuan， respectively； the cost of dispensing one bag of parenteral nutrition solution was 32.15 yuan （excluding the cost of disposable intravenous nutrition bags）. CONCLUSIONS The cost calculation method and data of different types of intravenous drugs obtained in this study can provide reference for relevant departments to formulate and adjust PIVAS fee standards.
