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.

Purpose To investigate the diagnostic value of immunohistochemical(IHC)and molecular markers in diffuse pleural mesothelioma(DPM).Methods A total of 114 cases of DPM were retrospectively analyzed for clinical and imaging manifestations,histologic subtype and tumor grade.The positivity rates of Calretinin,WT-1,CK5/6,MC,D2-40,UPK3B,and GATA3 were assessed by IHC,and the loss rates of BAP-1 and MTAP were determined.The concordance between MTAP IHC and p16 gene fluorescence in situ hybridization(FISH)status was calculated,a-long with the sensitivity and specificity of MTAP IHC relative to p16 FISH.Results Among the 114 DPM patients,66(57.9％)were male and 48(42.1％)were female,with a mean age of 58.1 years(range 16-85 years).Imaging predominantly demonstrated pleural effusion and multiple pleural nodules(55.3％,63/114).Histologically,epitheli-oid,sarcomatoid and biphasic subtypes accounted for 88(77.2％),17(14.9％)and 9(7.9％)cases,respectively.Within the epithelioid group,low and high-grade tumors numbered 69(78.4％)and 19(21.6％),respectively.In epithelioid DPM,the highest IHC positivity rates were observed for Calretinin(92.4％,81/88),D2-40(90.0％,79/88)and WT-1(90.0％,79/88).In sarcomatoid DPM,D2-40(76.5％,13/17),WT-1(64.7％,11/17),and Cal-retinin(29.4％,5/17)showed the greatest positivity.UPK3B was positive in epithelioid(59.1％,39/66)and bi-phasic cases(66.7％,4/6),but was absent in sarcomatoid tumors(0/12).Among all DPM cases,loss rates were 47.3％(53/112)for BAP-1 and 19.2％(20/104)for MTAP by IHC,p16 gene deletion by FISH was 31.5％(34/108);Concordance between MTAP IHC and p16 FISH was 81.0％(81/100);MTAP IHC had a specificity of 95.5％(64/67)and sensitivity of 51.5％(17/33)relative to p16 FISH.Additionally,GATA3 was highly expressed in sarco-matoid DPM(76.5％,13/17).UPK3B positivity differed significantly between thoracoscopic DPM(59.2％,32/54)and percutaneous biopsy samples(36.7％,11/30)in epithelioid DPM(P＜0.05).WT-1 positivity was higher in thoracoscopic than percutaneous samples of sarcomatoid DPM(90.0％ vs 28.6％,P=0.009).Conclusion Calreti-nin,D2-40,and WT-1 are highly sensitive mesothelial markers and should serve as first-line IHC stains in DPM diag-nosis.UPK3B is diagnostically valuable in epithelioid DPM,GATA3 may complement the diagnosis of sarcomatoid DPM,and MTAP IHC can be used as a surrogate or adjunct to p16 FISH.

Objective:To investigate the distribution of iodine and other chemical elements in soil, grain and vegetables in different water iodine areas of Xi'an City, and to provide theoretical basis for prevention and treatment of iodine related diseases and water improvement measures.Methods:From September to November 2021, a stratified cluster sampling method was used to select three survey villages in Xi'an, namely Yehu Village, Xingbei Village, and Quanzhong Village, where the iodine level of residents' drinking water < 10, 10 - 100, and > 100 μg/L. Drinking water samples were collected from seven survey sites based on the source of domestic drinking water to determine the iodine level of the water. At the same time, soil samples of cultivated land, residents' grains (wheat, corn), and vegetables were collected from survey villages to determine the content of 14 elements including calcium, iron, magnesium, chromium, nickel, copper, zinc, cadmium, lead, arsenic, mercury, selenium, iodine, and fluoride.Results:The iodine level in the water of 7 survey sites in three survey villages was 5.80, 6.40, 25.51, 42.20, 53.90, 111.65, and 177.63 μg/L, respectively. A total of 70 samples of soil, 65 samples of wheat, 76 samples of corn, and 141 samples of vegetables were collected. Among them, the levels of various elements in vegetables and grains were lower than those in the soil. Only calcium and fluoride were higher in vegetables than in grains, while iron, chromium, copper, zinc, selenium, and iodine were lower in vegetables than in grains. According to the range of water iodine level, there were statistically significant differences in the content of calcium, iron, chromium, nickel, copper, zinc, mercury, iodine, and fluoride in soils from different water iodine regions ( Fcalcium, iron, chromium, nickel = 42.04, 13.55, 12.22, 11.20, Hcopper, zinc, mercury, iodine, fluoride = 14.27, 9.19, 14.72, 25.14, 16.50, P < 0.05). The comparison of magnesium, zinc, cadmium, arsenic, and selenium content in wheat showed statistically significant differences ( Fadmium, selenium = 6.34, 3.31, Hmagnesium, zinc, arsenic = 6.12, 11.55, 6.23, P < 0.05). The comparison of calcium, iron, magnesium, chromium, nickel, copper, zinc, cadmium, lead, arsenic, mercury, iodine, and fluoride content in corn showed statistically significant differences ( Fmagnesium, chromium, nickel, copper, zinc, iodine = 18.89, 13.76, 17.86, 24.17, 28.46, 15.96, Hcalcium, iron, cadmium, lead, arsenic, mercury, fluoride = 11.57, 40.53, 26.50, 33.05, 33.73, 36.01, 29.21, P < 0.05). The comparison of calcium, iron, magnesium, chromium, zinc, cadmium, lead, arsenic, mercury, and selenium content in vegetables showed statistically significant differences ( H = 23.93, 8.12, 10.03, 7.01, 16.09, 18.36, 23.07, 6.51, 27.67, 7.86, P < 0.05). Conclusions:There are significant differences in the distribution of 14 elements in soil, grain, and vegetables in different water iodine regions. In addition to drinking water, precise guidance should also be provided based on the iodine content in soil, grain, and vegetables in different water iodine areas.

Objective To investigate the neuroprotective effect of Dendrobium nobile Lindl(DNL)extract in a Caenorhabditis elegans(C.elegans)model of Parkinson's disease(PD).Methods C.elegans NL5901 and 6-hydroxydopamine(6-OHDA)induced N2,BZ555,PD4521,and CB7272 C.elegans strains were treated with DNL 7.5,15,and 30 mg/L.The survival rate,basal slowing response rate,α-synuclein(α-syn)aggregation,dopaminergic neurons(DNs),mitochondrial distribution density of body wall muscle cells,and protein levels in the membrane were observed.In addition,reactive oxygen species(ROS),superoxide dismutase(SOD)and glutathione(GSH)in 6-OHDA induced N2 was detected to explore the effect of DNL on the antioxidative stress ability of PD C.elegans models.Results Compared with that in the model group,the DN fluorescence intensity was significantly increased in nematodes treated with DNL and levodopa(L-DOPA)(P＜0.05,P＜0.0001),α-syn aggregation was significantly decreased(P＜0.05,P＜0.001,P＜0.0001),the basal slowing rate(P＜0.05,P＜0.01,P＜0.001),mitochondrial density(P＜0.05,P＜0.01,P＜0.001),mitochondrial intima protein content(P＜0.05,P＜0.001,P＜0.0001),SOD content(P＜0.05),and GSH content were all increased.The ROS content was reduced in nematodes(P＜0.01).The lifespans of N2 wild-type and PD C.elegans models were prolonged after DNL treatment(P＜0.05,P＜0.01,P＜0.001).Conclusions DNL can effectively improve motor paralysis in a C.elegans PD model,improve DN degradation,inhibit α-syn aggregation and neuronal damage,increase the antioxidative stress ability,and slow the aging process in C.elegans.

Objective To analyze the clinical characteristics of cancer related anemia(CRA)in older cancer patients undergoing multi-line anti-tumor treatment.Methods A cross-sectional study was conducted,including patients with CRA who were≥65 years old and had received or were currently undergoing multi-line treatment at 9 hospitals in Beijing from June 1,2018 to September 30,2023.Data on gender,age,past history,family history,tumor type,metastasis site,clinical symptoms,blood routine,specialized examination for anemia,anti-tumor and anemia correction treatment were collected.The basic characteristics of the included patients,clinical symptoms,the status of blood cell reduction,treatment conditions,and the distribution of traditional Chinese medicine(TCM)syndrome characteristics were analyzed.Results A total of 602 patients were included.The tumor types included lung cancer,colorectal cancer,gastric cancer,esophageal cancer,breast cancer,gynecological tumors,lymphoma.The overall median hemoglobin(HGB)level was 99.00(88.00,107.00)g/L.The HGB levels of patients with different tumor types showed significant differences(P<0.001).The HGB levels of patients with gynecological tumors were significantly lower than those of patients with colorectal cancer,lung cancer and esophageal cancer(P<0.05).The most common clinical symptoms were fatigue,loss of appetite,irregular bowel movements and pain.In terms of anti-tumor treatment,405 patients were receiving multi-line anti-tumor treatment(including combined chemotherapy,combined radiotherapy,combined targeted therapy,and combined immunotherapy),197 patients were receiving symptomatic supportive treatment after multi-line anti-tumor treatment.In terms of anemia correction treatment,183 patients received erythropoietin,folic acid,iron,vitamin B12,or blood transfusion,while 293 patients received TCM for correcting anemia(including Chinese patent medicines,Chinese herbal decoctions,combinations of Chinese patent medicines and Chinese herbal decoctions).Specialized tests for anemia,such as serum iron,total iron binding capacity,transferrin saturation,transferrin,erythropoietin et al,have a detection rate of only 3.65%～27.91%.In terms of the characteristics of TCM syndromes,the main TCM syndrome types of the patients were as follows:syndrome of spleen-stomach weakness,syndrome of qi and blood deficiency,syndrome of heart-spleen deficiency,syndrome of spleen-kidney yang deficiency,syndrome of liver and kidney yin deficiency.Some patients also have the accompanying symptoms of internal binding of static blood and poison,phlegm dampness retention.Further comparison revealed that the HGB level of older patients with CRA who had syndrome of spleen-stomach weakness was significantly lower than patients with other symptom types(P<0.001).The HGB level of patients with syndrome of qi and blood deficiency was significantly lower than patients with syndrome of spleen-kidney yang deficiency(P<0.01)and syndrome of liver and kidney yin deficiency(P<0.001).Patients with symptoms of internal binding of static blood and poison,or symptoms of phlegm dampness retention had significantly lower HGB levels compared to those without accompanying symptoms(P<0.01).Conclusion The rate of specialized blood test for anemia in older patients with CRA was relatively low.The most common TCM syndrome types were syndrome of spleen-stomach weakness and syndrome of qi and blood deficiency.The overall treatment rate was also low.The screening,specialized diagnosis and monitoring of older patients with CRA need to be given more attention,and treatment methods such as TCM,Western medicine,and integrated TCM-Western medicine should be selected based on the patient's condition.

Objective:To construct a health education checklist for safety management of oral antitumor drugs in tumor patients, so as to provide a guidance for clinical nurses in practice, thereby improving the drug safety of patients taking oral antitumor drugs.Methods:Based on the cognition-behavior theoretical framework, a preliminary draft of a health education checklist for safety management of oral antitumor drugs in tumor patients was developed through literature review. The Delphi method was used to conduct consultations with 17 experts from July to September 2024 to revise and add or delete the contents of the checklist based on the experts' assignments of importance to the indicators at each level and the textual comments made.Results:A total of two rounds of expert consultation were conducted. The final established health education checklist for safety management of oral antitumor drugs in tumor patients included 4 primary and 28 secondary indicators. In the two rounds of consultation, the positive coefficient of experts was 100.0%, the coefficient of expert authority was 0.93, the coefficients of variation for the two rounds of expert ratings were 0 to 0.173 and 0 to 0.151, and the coefficients of Kendall's concordance were 0.141 (χ 2=74.461, P<0.001) and 0.113 (χ 2=59.549, P=0.002) , respectively. Conclusions:The health education checklist for safety management of oral antitumor drugs in tumor patients has good scientific, reliable and clinical practical value, which can provide scientific, standardized and convenient practical guidance for clinical nurses to implement health education on drug safety management for patients taking oral antitumor drugs.
