OBJECTIVE To evaluate the effect of clinical pharmacists participating in the treatment of chronic heart failure （CHF） based on the clinical pharmacy pathway （CPP）. METHODS Totally 226 CHF patients recruited from August 24th， 2024 to March 14th， 2025， were divided into an observation group and a control group based on the random number table method， with 113 cases in each group. All patients were treated with conventional therapy. The observation group was additionally given CPP management （including pharmaceutical care during hospitalization， the formulation of individualized discharge medication regimens， and pharmaceutical follow-up after discharge）. The cardiac function parameters at admission， at discharge， at 3 and 6 months after discharge， drug use at 6 months after discharge， economic indicators， as well as the readmission rate and mortality rate at 6 months after discharge were compared between the two groups. Morisky Medication Adherence Scale-8 Items （MMAS-8）， Somatic Self-rating Scale （SSS） and Patient Health Questionnaire-9 （PHQ-9） scores were compared at admission， at discharge and at 3 and 6 months after discharge. RESULTS Six months after discharge， 24 patients dropped out. Eventually， 104 patients in the observation group and 98 patients in the control group completed the study. Compared with at admission， New York Heart Association （NYHA） cardiac functional classification， left ventricular ejection fraction （LVEF） and N -terminal pro-B-type natriuretic peptide （NT-proBNP） of both groups of patients at discharge as well as at 3 and 6 months after discharge were significantly improved； moreover， the improvements at 3 and 6 months after discharge were significantly better than those at discharge. Meanwhile， the above indexes （except for NYHA cardiac functional classification at discharge， NT-proBNP and NYHA cardiac functional classification at 3 months after discharge） of the observation group at discharge， at 3 and 6 months after discharge were significantly better than the control group （ P ＜0.05）. The utilization rates of angiotensin converting enzyme inhibitor （ACEI）/angiotensin Ⅱ receptor blocker （ARB）/angiotensin receptor neprilysin inhibitor （ARNI）， the proportion of β-blockers reaching the target dose， the utilization rate of sodium-glucose linked transporter 2 inhibitor （SGLT2i）， and the proportion of SGLT2i reaching the target dose in the observation group were significantly higher than the control group （ P ＜0.05）， and the proportion of drugs and readmission rate were significantly lower than the control group （ P ＜0.05）. Compared with at admission， MMAS-8 scores of the patients in the observation group at discharge， at 3 and 6 months after discharge were significantly increased， while SSS and PHQ-9 scores were significantly lowered （ P ＜0.05）. And all the above scores gradually decreas ed with the extension of discharge time （ P ＜0.05）. CONCLUSIONS Clinical pharmacists can utilize CPP to significantly improve patients’ cardiac function， medication adherence， somatic symptoms and depression. Additionally， they can significantly improve the utilization rates of ACEI/ARB/ARNI and SGLT2i， as well as the proportion of target doses of β-blockers and SGLT2i， while simultaneously reducing readmission rates.

ObjectiveTo investigate the value of liver stiffness measurement （LSM） and spleen stiffness measurement （SSM） measured by two-dimensional shear wave elastography （2D-SWE） in the diagnosis of severe portal hypertension （SPH） and high-risk varices （HRV）， and to provide a basis for noninvasive assessment of portal hypertension. MethodsA prospective study was conducted among 78 patients with cirrhotic portal hypertension who were treated in Liver Research Center of Beijing Friendship Hospital， Capital Medical University， from December 2019 to April 2023. According to hepatic venous pressure gradient （HVPG）， the patients were divided into 6 mmHg≤HVPG<12 mmHg group， 12 mmHg≤HVPG<20 mmHg group， and HVPG ≥20 mmHg group. All patients underwent gastroscopy and 2D-SWE within 1 week after HVPG measurement， and SWE-LSM and SWE-SSM measured by 2D-SWE were recorded. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. With HVPG and gastroscopy findings as the gold standard， the receiver operating characteristic （ROC） curve was plotted and the area under the ROC curve （AUC） was calculated to evaluate diagnostic performance， while the DeLong test was used for comparison of AUC. The Pearson or Spearman correlation analysis was used to investigate the correlation between variables， and the linear regression analysis and the Logistic regression analysis were used to investigate the influencing factors for HVPG and HRV. ResultsThe mean HVPG was 18.1±6.4 mmHg for the patients enrolled in this study， and HRV was observed in 62 patients （79.5%）. Both SWE-LSM and SWE-SSM were significantly positively correlated with HVPG （r=0.413 and 0.633， both P<0.001）， with an AUC of 0.812 and 0.902， respectively， in the diagnosis of HVPG≥12 mmHg and an AUC of 0.804 and 0.789， respectively， in the diagnosis of HVPG≥20 mmHg （all P>0.05）. The multivariate linear regression analysis showed that SWE-SSM was an independent influencing factor for HVPG （β=0.17， P<0.001）. In the diagnosis of HRV， only SWE-SSM showed a significant positive correlation with HRV （r=0.432， P<0.001）， with a better diagnostic performance than SWE-LSM in terms of AUC （0.808 vs 0.642， Z=2.775， P=0.006）. The multivariate Logistic regression analysis showed that platelet count was an independent influencing factor for HRV （odds ratio=0.97， P=0.014）. ConclusionSWE-SSM is closely correlated with both HVPG and HRV， showing a good performance in the diagnosis of SPH and HRV， and therefore， it is expected to become an effective noninvasive tool for assessing portal hypertension.

Glioblastoma multiforme(GBM)is a grade 4 glioma with the highest malignancy and invasiveness in the central nervous system,accounting for approximately 30％of all tumors in the central nervous system.Due to the unclear pathogenesis of GBM,there is currently no specific target for the treatment of GBM.Temozolomide(TMZ)is the only first-line chemotherapeutic drug for the treatment of GBM,but suffers from a low drug response rate and high susceptibility to drug resistance.Therefore,the development of new targets and novel GBM therapeutic agents is an urgent clinical problem.Pentraxin 3(PTX3),a member of the pentameric protein superfamily,has been shown to have a promotive effect on a variety of tumors.Increasing evidences showed that PTX3 played a crucial role in the progression of GBM.PTX3 can promote the proliferation,migration and invasion ability of GBM cells,increase the angiogenesis ability in the GBM microenvironment and malignant progression of GBM.In the article,the structure,physiological function,expression regulation,role and mechanism of PTX3 in GBM were mainly reviewed,with a view to provide guidance for PTX3 as a potential drug target for the treatment of GBM.

Objective To compare the safety and efficacy of vancomycin in obese patients guided by trough concentration and AUC24h/MIC,and to provide data for individualized administration of vancomycin in obese patients.Methods We retrospectively collected the data of obese adult patients(BMI 30 kg/m2)who had severe infection caused by gram-positive cocci and treated with vancomycin intravenously in two Grade A tertiary hospitals in Shanghai from 2012 to 2024.The patients were assigned to trough concentration monitoring group or AUC24h/MIC monitoring group according to the therapeutic drug monitoring(TDM)method at the time of admission.Nephrotoxicity and efficacy were compared between the two groups of patients.Results A total of 22 obese patients were included in this study,including 12 in the trough concentration monitoring group and 10 in the AUC24h/MIC monitoring group.No significant difference was found between the two groups in gender,age,BMI,creatinine clearance before treatment,underlying disease,site of infection,pathogen type,or concomitant medications.The proportion of ICU admission was higher in AUC24h/MIC monitoring group.The length of ICU stay,vancomycin treatment duration,bacterial clearance rate and comprehensive efficacy rate did not show significant difference between the two groups.The average daily dose of vancomycin in trough concentration monitoring group was significantly lower than that in A UC24h/MIC monitoring group[(1.63±0.59)g vs(2.29±0.72)g,P=0.026].The average treatment duration was not significantly different between the two groups[(15.33±10.28)d vs(14.90±6.92)d,P=0.911].Compared with the trough concentration monitoring group,the initial peak concentration[(30.99±16.22)mg/L vs(19.41±5.42)mg/L,P=0.025]and overall peak concentration[(33.67±16.53)mg/L vs(22.08±3.96)mg/L,P=0.045]of vancomycin were lower in theAUC24h/MIC monitoring group,but the initial trough concentration[(11.03±8.66)mg/L vs(6.33±4.45)mg/L,P=0.139]and overall trough concentration[(13.75±9.74)mg/L vs(9.74±4.24)mg/L,P=0.218]were similar in the two groups.Vancomycin-associated nephrotoxicity did not occur in any group,but 41.7％of the patients in the trough concentration monitoring group reached the threshold of renal toxicity,i.e.trough concentration ≥15 mg/L.Conclusions Vancomycin treatment with conventional dosing regimen still have good clinical efficacy in obese adult patients.Vancomycin therapy guided by A UC24h/MIC can achieve the target value at lower concentration or exposure,which is promising for reducing vancomycin-associated nephrotoxicity.

Objective:To evaluate the effect of dexmedetomidine on the viability of dopaminergic neurons in the ventral tegmental area (VTA) of morphine-addicted mice.Methods:Experiment Ⅰ Thirty SPF healthy adult male C57BL/6 mice, aged 8 weeks, weighing 20-25 g, were divided into 3 groups ( n=10 each) using the random number table method: normal saline group (NS group), dexmedetomidine 50 μg/kg group (DEX50 group), and dexmedetomidine 100 μg/kg group (DEX100 group). A morphine addiction model was established by intraperitoneal injection of increasing doses of morphine (10, 20, 30, 40, 50 and 50 mg/kg) for 6 consecutive days in mice. After the successful establishment of the model, dexmedetomidine 50 and 100 μg/kg were intraperitoneally injected for 14 consecutive days in group DEX50 and group DEX100 respectively, while normal saline was given instead in group C. The conditioned place preference (CPP) experiment was conducted every other day. Experiment Ⅱ Thirty SPF healthy adult male C57BL/6 mice, aged 8 weeks, weighing 20-25 g, were divided into 3 groups ( n=10 each) by the random number table method: control group (C group), morphine group (Mor group) and dexmedetomidine 50 μg/kg group (DEX50 group). Normal saline was intraperitoneally injected for 10 consecutive days in group C. Morphine with increasing doses was intraperitoneally injected for 6 days, and then normal saline was intraperitoneally injected for 4 consecutive days in group Mor. Morphine with increasing doses was intraperitoneally injected for 6 days, and then dexmedetomidine 50 μg/kg was intraperitoneally injected for 4 consecutive days in group DEX50. The mice were anesthetized at 90 min after the last intraperitoneal injection, brain tissues were harvested, and the corresponding brain slices of the VTA were selected for c-Fos immunofluorescence staining. Experiment Ⅲ Ten dopamine transporter-Cre recombinase mice were divided into 2 groups ( n=5 each) by the random number table method: morphine group (Mor group) and morphine+ dexmedetomidine 50 μg/kg group (Mor+ DEX group). Stereotaxic viral injection was performed in the brain. rAAV-EF1α-DIO-GCaMP6s was injected into the VTA and an optical fiber was implanted. Three weeks later, a morphine addiction model was established based on Experiment Ⅰ for the CPP experiment, morphine was intraperitoneally injected in group Mor, and morphine and dexmedetomidine were intraperitoneally injected in group Mor+ DEX. The viral fluorescence signals were recorded at 5 min before and 20 min after the drug administration in the three groups. Results:Experiment Ⅰ There was no statistically significant difference in the CPP scores after developing the morphine addiction model among the three groups ( P>0.05). Compared with group NS, the CPP scores were significantly decreased at 4-14 days of the continuous administration in group DEX50 and group DEX100 ( P<0.05). Experiment Ⅱ Compared with group C, the number of c-Fos positive cells in the VTA was significantly increased in group Mor ( P<0.05). Compared with group Mor, the number of c-Fos positive cells in the VTA was significantly decreased in group DEX ( P<0.05). Experiment Ⅲ Compared with that before administration, the calcium signals of dopaminergic neurons in the VTA were significantly enhanced in group Mor ( P<0.05), and no statistically significant difference was found in the calcium signals of dopaminergic neurons in the VTA in group Mor+ DEX ( P>0.05). Compared with group Mor, no statistically significant difference was found in the calcium signals of dopaminergic neurons in the VTA before drug administration ( P>0.05), and the calcium signals of dopaminergic neurons in the VTA were significantly weakened after administration in group Mor+ DEX ( P<0.05). Conclusions:The mechanism by which dexmedetomidine promotes the extinction of morphine addiction is related to the inhibition of the viability of dopaminergic neurons in the VTA of mice.

Eosinophilic gastroenteritis(EG)is a rare disease characterized by abnormal infiltration of eosinophils(Eos)in gastrointestinal tissues.Due to the unclear pathogenesis of EG and the lack of effective therapeutic drugs,research on its novel mechanisms,targets and drugs is critical.This article starts by outlining the research progress in the pathogenesis of EG,involving IgE mediated typeⅠimmediate allergic reactions and T helper 2 cell(Th2)mediated delayed allergic reactions.Then,the related targets of EG are summarized,including Th2 cytokines and factors regulating Eos function,but there has been no breakthrough in the treatment of these targets.Finally,the therapeutic drugs for EG are reviewed,such as glucocorticoids,antiallergic drugs and biologics.The advantages and disadvantages of various drugs are also described.However,these drugs cannot meet the current demands of clinical treatment and there is an urgent need to develop novel therapeutic drugs.It is believed that multi-target therapy is an ideal treatment for EG,and that traditional Chinese medicine and natural products should be the priorities of research and development for EG therapeutic drugs in the future.This review is expected to provide new ideas for the clinical treatment strategies and drug development of EG.
