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.

ObjectiveTo investigate the distribution of traditional Chinese medicine (TCM) syndrome patterns among postmenopausal women with dyslipidemia, and to examine the correlations of lipid parameters with bone mineral density (BMD) and bone metabolism markers across common TCM syndrome patterns, thereby providing a clinical reference for individualized integrative traditional Chinese and western medicine interventions stratified according to TCM syndrome patterns. MethodsA multi-center cross-sectional study was conducted among postmenopausal women aged 45-64 years with dyslipidemia. TCM syndromes were determined using a scale-based scoring method. BMD measurements were collected, and fasting venous blood samples were assayed for lipid parameters including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), and bone metabolism biomarkers including osteocalcin (OST), total procollagen type Ⅰ N-terminal propeptide (P1NP), alkaline phosphatase (ALP), bone-specific alkaline phosphatase (BALP), β-isomerized C-terminal telopeptide of type Ⅰ collagen (β-CTX), 25-hydroxyvitamin D [25(OH)D], and thyroid-stimulating hormone (TSH). Chi-square tests were used to compare the distribution of dyslipidemia across different TCM syndromes. Spearman's rank correlation analysis was performed to evaluate the correlations between TCM syndrome patterns and dyslipidemia, as well as the correlations of lipid parameters with BMD and bone metabolism markers within each syndrome pattern. ResultsA total of 506 postmenopausal women with dyslipidemia were included, comprising 172 cases of spleen-kidney yang deficiency syndrome (33.99%), 163 cases of phlegm-turbidity obstruction syndrome (32.21%), 118 cases of liver-kidney yin deficiency syndrome (23.32%), 33 cases of qi stagnation and blood stasis syndrome (6.52%), and 20 cases of yin deficiency and yang hyperactivity syndrome (3.95%). Phlegm-turbidity obstruction syndrome was negatively correlated with TC abnormality (r=-0.120, P=0.007) and positively correlated with TG abnormality (r=0.246, P<0.001). Spleen-kidney yang deficiency syndrome and liver-kidney yin deficiency syndrome were both negatively correlated with TG abnormality (r=-0.101, P=0.023; r=-0.116, P=0.009, respectively). Further correlation analysis confirmed that phlegm-turbidity obstruction syndrome was negatively correlated with TC abnormality (r=-0.120) and significantly positively correlated with TG abnormality (r=0.246). Both the spleen-kidney yang deficiency syndrome and liver-kidney yin deficiency syndrome were negatively correlated with TG abnormality (r=-0.101 and r=-0.116, respectively). In patients with phlegm-turbidity obstruction syndrome, HDL-C was negatively correlated with BMD at the left femoral neck (r=-0.178, P=0.023) and at left total hip (r=-0.190, P=0.015). In patients with liver-kidney yin deficiency syndrome, TG was positively correlated with BMD at the lumbar spine (L1-L4) and left total hip (r=0.214, P=0.020; r=0.221, P=0.016, respectively). More significant correlations were observed in patients with spleen-kidney yang deficiency syndrome, TG was positively correlated with ALP (r=0.210, P=0.006); TC was positively correlated with TSH and 25(OH)D (r=0.153, P=0.045; r= 0.231, P=0.002, respectively); HDL-C was positively correlated with OST and 25(OH)D (r=0.156, P=0.040; r=0.228, P=0.003, respectively); and LDL-C was positively correlated with TSH and 25(OH)D (r=0.156, P= 0.041; r=0.182, P=0.017, respectively). In patients with liver-kidney yin deficiency syndrome, HDL-C was negatively correlated with TSH (r=-0.204, P=0.027). ConclusionThe association between dyslipidemia and skeletal health in postmenopausal women varies across TCM syndromes. Lipid abnormalities in women with phlegm-turbidity obstruction syndrome or liver-kidney yin deficiency syndrome are accompanied primarily by site-specific alterations in BMD, whereas those in women with spleen-kidney yang deficiency syndrome are reflected mainly in changes in bone metabolism markers. These findings suggest that targeted intervention strategies should be developed according to TCM syndrome characteristics for postmenopausal women with dyslipidemia.

Uveal melanoma(UM)is a rare but highly aggressive intraocular malignancy. Although it accounts for less than 5% of all melanoma cases, UM is the most common primary intraocular malignancy in adults. In recent years, advances in molecular targeted therapies and immunomodulatory strategies have provided new opportunities for the clinical management of UM. This review summarizes the pathogenesis, molecular biomarkers, and major therapeutic advances in UM, with particular emphasis on analyzing the research achievements and clinical application prospects of signaling pathway-targeted inhibitors, immune checkpoint inhibitors, and combination treatment strategies. The potential value of individualized treatment and the limitations of current therapeutic approaches are also discussed. Current evidence suggest that multidisciplinary intervention and precision molecular diagnosis and treatment may significantly improve the prognosis of patients with UM, providing references for future clinical research and the optimization of therapeutic strategies.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

BACKGROUND:Prolyl hydroxylase domain 2(PHD2)inhibitors can regulate bone metabolism and relieve osteoporosis in ovariectomized rats.cpd17 is a small molecule oral PHD2 inhibitor newly developed by China Pharmaceutical University.It is effective in the treatment of renal anemia with few side effects,but its effect on bone formation and bone resorption is still unclear. OBJECTIVE:To investigate the effects of cpd17 on mouse osteogenic precursor cells. METHODS:Osteogenic precursor cells were treated with cpd17.Alkaline phosphatase activity and extracellular matrix mineralization were measured,and the expression levels of osteogenesis-and osteoclastogenesis-related markers,as well as PHD2 and hypoxia-inducible factor 1α,were detected.After inhibition of the hypoxia-inducible factor 1α pathway using LW6(a hypoxia-inducible factor 1α pathway inhibitor),alkaline phosphatase activity and extracellular matrix mineralization were detected again,as well as the expression levels of osteogenesis-and osteoclastogenesis-related markers,PHD2 and hypoxia-inducible factor 1α. RESULTS AND CONCLUSION:cpd17 significantly enhanced alkaline phosphatase activity and extracellular matrix mineralization,up-regulated the expression of osteogenesis-related markers,down-regulated the expression of osteoclastogenesis-related markers,up-regulated the expression of hypoxia-inducible factor 1α,down-regulate the expression of PHD2.However,cpd17's effects were significantly attenuated by LW6.To conclude,the PHD2 inhibitor cpd17 promotes osteogenic differentiation and inhibits osteoclastic differentiation through activation of the hypoxia-inducible factor 1α signaling pathway.

BACKGROUND:The pathogenesis of diabetic peripheral neuropathy has not yet been clarified,and TAM(Tyro3,Axl,and MerTK)receptor tyrosine kinases can control apoptotic cells and suppress inflammatory responses in the central nervous system. OBJECTIVE:To investigate the difference of Mer receptor tyrosine kinase(MerTK)levels in plasma and sciatic nerve tissue of Sprague-Dawley rats with type 2 diabetes and diabetic peripheral neuropathy,and to study the correlation between MerTK and diabetic peripheral neuropathy. METHODS:Forty male Sprague-Dawley were randomly divided into control group with 15 rats,type 2 diabetes group with 10 rats,and diabetic peripheral neuropathy group with 15 rats.The control group was fed with ordinary diet,while the experimental groups were fed with high-fat and high-sugar diet.After 6 weeks,intraperitoneal injection of streptozotocin at the minimum dose of 35 mg/kg was administered in the two experimental groups.After 14 days,tail vein blood was collected to detect blood glucose.If blood glucose≥16.7 mmol/L,the model of type 2 diabetes was successfully established.Rats in the diabetic peripheral neuropathy group continued to be fed with a high-sugar and high-fat diet for 8 weeks.The sciatic nerve conduction velocity of rats was detected through live isolation under anesthesia.Blood samples were collected from the abdominal aorta,and the sciatic nerve tissue was collected.Histological changes of nerve fibers in each group were observed under a light microscope to confirm the success of diabetic peripheral neuropathy modeling.ELISA was used to detect peripheral blood glucose,blood lipids and serum MerTK levels in rats;hematoxylin-eosin staining was used to observe the histological changes in the sciatic nerve;immunofluorescence,immunohistochemistry and western blot were used to detect the expression of MerTK in the sciatic nerve tissue. RESULTS AND CONCLUSION:The Sprague-Dawley rat models of type 2 diabetes and type 2 diabetes peripheral neuropathy were successfully constructed,and the modeling rate of diabetic peripheral neuropathy was 80%.Compared with the control group,the blood glucose levels of rats in the type 2 diabetes and diabetic peripheral neuropathy groups were significantly higher(P<0.000 1),while the blood glucose level in the diabetic peripheral neuropathy group was higher than that in the type 2 diabetes group;and the sciatic nerve conduction velocity was significantly decreased(P<0.05),which was lower in the diabetic peripheral neuropathy group than the type 2 diabetes group.Histological examination:Compared with the control group,the sciatic nerve nuclei were reduced in the type 2 diabetes group,with some vacuolar degeneration and phagocytosis;in the diabetic peripheral neuropathy group,the cell body was swollen,the nuclear spacing was increased,vacuolar degeneration was observed,and the myelin sheath was partitioned and unsmooth,and lattice-like axons appeared.Serum MerTK levels were significantly higher in the diabetic peripheral neuropathy group than the control group.Expression of MerTK in the sciatic nerve tissue was significantly upregulated in the diabetic peripheral neuropathy group compared with the control group(P<0.05).To conclude,elevated levels of MerTK in plasma and sciatic nerve tissue of rats with diabetic peripheral neuropathy are presumably related to its anti-inflammatory and immunomodulatory effects.

Objective:
Accurate evaluation of inflammation severity in ulcerative colitis (UC) can guide treatment strategy selection. The potential value of the pericolic fat attenuation index (FAI) on CT as an indicator of disease severity remains unknown.This study aimed to assess the diagnostic accuracy of pericolic FAI in predicting UC severity.
Materials and Methods:
This retrospective study enrolled 148 patients (mean age 48 years; 87 males). The fat attenuation on CT was measured in four different locations: the mesocolic vascular side (MS) and opposite side of MS (OMS) around the most severe bowel lesion, the retroperitoneal space (RS), and the subcutaneous area. The fat attenuation indices (FAI MS, FAI OMS, and FAI RS) were calculated as the fat attenuation measured in MS, OMS, and RS, respectively, minus that of the subcutaneous area, and were obtained in the non-enhanced, arterial, and delayed phases. Correlations between the FAI and UC Endoscopic Index of Severity (UCEIS) were assessed using Spearman’s correlation. Predictors of severe UC (UCEIS ≥7) were selected by univariable analysis. The performance of FAI in predicting severe UC was evaluated using the area under the receiver operating characteristic curve (AUC).
Results:
The FAIMS and FAI OMS scores were significantly higher than FAI RS in three phases (all P < 0.001). The FAIMS and FAI OMS scores moderately correlated with the UCEIS score (r = 0.474–0.649 among the three phases). Additionally, FAI MS and FAI OMS identified severe UC, with AUC varying from 0.77 to 0.85.
Conclusion
Increased CT attenuation of pericolic adipose tissue could serve as a noninvasive marker for evaluating UC severity. FAI MS and FAI OMS of three phases showed similar prediction accuracies for severe UC identification.

ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates (P<0.05). Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r0=5, α=0.3, β1=0.08, β2=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (rt≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

Objective To explore the clinical value of inflammatory prognostic index combined with dual-source CT perfusion imaging in predicting early response of hepatocellular carcinoma(HCC)after transcatheter hepatic artery chemoembolization(TACE).Methods A total of 25 patients with HCC,who met the inclusion criteria and received initial TACE at the First Affiliated Hospital of Dali University of China from November 2022 to November 2023,were prospectively collected.CT perfusion scan was performed before TACE as well as in 30-40 days after TACE,and blood routine and blood biochemical data were collected.The modified Response Evaluation Criteria in Solid Tumors(mRECIST)was used to evaluate postoperative enhanced CT manifestations.Patients obtaining complete remission(CR)or partial remission(PR)were classified as effective group(n=14),and patients obtaining stable disease(SD)or progression disease(PD)were classified as ineffective group(n=11).The differences in CT perfusion imaging parameters and inflammatory parameters between the two groups were analyzed,and the predictive values of preoperative CT perfusion imaging parameters and inflammatory parameters for postoperative early response of HCC were evaluated.The cutoff value was taken at the maximum Youden index.Univariate analysis and multivariate analysis were used to analyze the effect of CT perfusion imaging parameters,inflammatory parameters and clinical features on the prognosis.The nomogram prediction model was constructed by using R software.Results The post-TACE arterial liver perfusion(ALP),hepatic perfusion index(HPI),blood flow(BF)and blood volume(BV)were significantly lower than their pre-TACE values(all P<0.05).Afer TACE portal vein perfusion(PVP)was obviously higher than that before operation(P<0.05).No statistically significant differences in the mean transit time(MTT),flow extraction product(FED),C-reactive protein(CRP),albumin(ALB),neutrophil/lymphocyte ratio(NLR)and inflammatory prognosis index(IPI)existed between the pre-TACE values and post-TACE values(all P>0.05).The pre-TACE ALP,BF and FED in the effective group were significantly higher than those in the ineffective group,while the pre-TACE CRP and IPI in the effective group were remarkably lower than those in the ineffective group(P<0.05).There were no statistically significant differences in pre-TACE PVP,HPI,MTT,BV,ALB and NLR between the effective group and the ineffective group before(all P>0.05).In the effective group,the pre-TACE ALP,HPI,BF,BV and FED were obviously higher than their post-TACE values(all P<0.05)preoperative PVP was significantly lower than postoperation(P<0.05),while no statistically significant differences in MTT,CRP,ALB,NLR and IPI existed between the pre-TACE values and the post-TACE values(all P>0.05).In the ineffective group,the pre-TACE HPI was prominently higher than the post-TACE value(P<0.05),while no statistically significant differences in ALP,PVP,BF,BV,MTT,FED,ALB,CRP,NLR and IPI existed between the pre-TACE values and the post-TACE values(all P>0.05).The pre-TACE ALP,BF,BV,FED,CRP and IPI had high predictive values in judging early response of HCC after TACE(all P<0.05),the AUC values were 0.831,0.779,0.740,0.753,0.779 and 0.805 respectively,and the optimal cutoffs were 33.280 mL/100 mL min,61.860 mL/100 mL min,5.885 mL/100 mL,29.725 mL/100 mL min,30.465 mg/L,1.885 respectively.ALP combined with CRP had the highest predictive value for post-TACE early response of HCC,with an AUC of 0.968(95%CI:0.906-1.000,P<0.05),ALP combined with IPI could significantly improve the predictive value,with an AUC of 0.961(95%CI:0.894-1.000,P<0.05),with the sensitivity and specificity being 0.929 and 0.909 respectively.Multivariate analysis showed that pre-TACE ALP and CRP were the independent influencing factors for post-TACE early response of HCC(P<0.05).The nomogram prediction model constructed based on the pre-TACE ALP and CRP could effectively predict the post-TACE early response of HCC,and the AUC value was 0.968(95%CI:0.908-1.000).Conclusion ALP and CRP can be used to predict the post-TACE early response of HCC,and the combination use of ALP and CRP can significantly improve the predictive value.
