Thomas Percival published the first edition of Medical Ethics in 1803 and is often regarded as the founder of modern medical ethics. After settling in Manchester in 1767， he established a reputation locally through his outstanding medical research and clinical work， contributions to public health affairs， and influence of his ethical works. In 1788， when a dispute arose among the medical staff at the Manchester Infirmary， Percival， as the hospital’s extraordinary physician and a highly respected figure in the region’s medical community， was commissioned to draft a code of conduct for medical staff. Taking this opportunity， he completed and published the book named Medical Ethics， which subsequently exerted a profound impact on the professional norms of physicians in the United Kingdom and the United States.

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.

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:To evaluate the clinical effect of different types of aortic root replacement in adolescent patients with aortic root aneurysm by analyzing the perioperative and follow-up conditions of surgical treatment for adolescent aortic root aneurysm.Methods:The clinical data of patients aged ≤18 years who were admitted to the Beijing Anzhen Hospital from November 2012 to February 2025, diagnosed with aortic root aneurysm by ultrasound or aortic computed tomography angiography (CTA) and requiring surgical intervention, were collected retrospectively. They were divided into the valve-sparing aortic root replacement group (David operation group) and the aortic root replacement group (Bentall operation group) according to the surgical method. The perioperative results and long-term follow-up results of the two groups were analyzed. Kaplan-Meier survival curves were drawn to compare the reoperation intervention rate between the two groups.Results:A total of 25 patients were included in this study, including 17 in the Bentall group and 8 in the David group. There were no statistically significant differences in gender, age, blood routine, liver and kidney function, coagulation function, and electrolyte internal environment between the two groups (all P>0.05). There were no statistically significant differences in operation time and intensive care unit stay between the two groups (all P>0.05). Compared with the Bentall operation group, the intraoperative blood loss in the David operation group was more ( P<0.05). During the follow-up, no reoperation occurred in the Bentall operation group, while 3 patients in the David operation group had long-term re-intervention. The long-term reoperation intervention rate in the David operation group was higher than that in the Bentall group ( P=0.042), but there was no statistically significant difference in the aortic valve-related surgical intervention rate between the two groups ( P=0.15). Conclusions:For adolescent patients with aortic root aneurysm, although David operation may face long-term reoperation intervention, this intervention may not be due to the difference in surgical methods. Both Bentall operation and David operation are safe and reliable, with good perioperative results and stable medium and long-term prognosis.

Objective:To analyse the clinical characteristics of 214 cases of paediatric high altitude pulmonary edema（HAPE）and the efficacy of dexamethasone in adjunctive therapy.Methods:This retrospective study analyzed 214 pediatric cases of HAPE admitted to the Department of Paediatrics of the General Hospital of Tibetan Military between June 2015 to June 2017 and June 2019 to June 2021.Patients were divided into dexamethasone-treated group and dexamethasone-untreated group.Baseline data，clinical characteristics were collected to evaluate the treatment efficacy and drug side effects.Results:There were 107 children in each of the two groups with a median age of 8（5，11）years. The median age of the dexamethasone-treated group was 9（6，12）years and the mean age of the dexamethasone-untreated group was 7（3，10）years. The proportion of male children was 69.60%（149/214）；the onset of illness was mostly concentrated within 72 hours，accounting for 97.20%（208/214）of the cases；83.18%（178/214）of the cases had symptoms of combined upper respiratory tract infection before entering the plateau. The most important clinical symptoms of the children were cough（86.92%，186/214），cyanosis（70.09%，150/214），and shortness of breath（66.36%，142/214）. The proportion of auscultatory rhonchi was 83.18%（178/214），and all cases showed positive findings on chest radiography. After the dexamethasone regimen，the overall cure rate of the children was 94.39%，the average disappearance time of the symptoms and signs was（40.52±7.85）h，and the average hospital stay was（3.60±1.90）d. After treatment with the dexamethasone-free regimen，the overall cure rate was 92.52%，the mean time to disappearance of symptoms and signs was（42.10±7.62）h，and the mean length of stay in the hospital was(3.84±2.08)d. There was no significant difference in the cure rate，the disappearance time of symptoms and signs，and the average hospitalisation days between the two groups（ P>0.05），but a total of 11 children in the dexamethasone-treated group experienced adverse drug reactions，and no children in the dexamethasone-untreated group experienced adverse drug reactions. Conclusion:Han Chinese male children，particularly those with upper respiratory infections，should be closely monitored for HAPE risk within three days of ascending to high altitudes. This study does not recommend the use of dexamethasone for pediatric HAPE due to the lack of therapeutic benefits and potential adverse effects.

Objective To observe the efficacy of Venovo venous stent for treating post-thrombotic syndrome(PTS)after lower extremity deep venous thrombosis(DVT).Methods A total of 61 patients with PTS after lower extremioty DVT who underwent iliac vein stent implantation were retrospectively enrolled,including 33 cases underwent Venovo stent(Venovo stent group)and 28 cases underwent conventional stent implantation(conventional stent group).The technical success rates and perioperative complications,Villalta score and venous clinical severity score(VCSS)before and 6 and 12 months after treatment,as well as the primary stent patency were compared within and between groups.Results The technical success rate was 100%in both groups,and no significant difference of the incidence of perioperative complications was found between groups(P=0.187).There was no significant difference of Villalta score nor VCSS between groups before treatment(both P＞0.05),while significant decrease of Villalta score was noticed before and 6 or 12 months after treatment within both groups(all P＜0.05).No significant difference of Villalta score nor VCSS was found 6 months after treatment between groups(both P＞0.05),while significant difference of Villalta score and VCSS were observed in Venovo stent group compared with those in conventional stent group 12 months after treatment(both P＜0.05).No significant difference of primary stent patency rate was found between groups 6 and 12 months after treatment(both P＞0.05).Conclusion Venovo venous stent could be used to effectively treat PTS after lower extremity DVT.

Sudden sensorineural hearing loss(SSNHL)is an idiopathic sensorineural hearing loss of at least 30 dB over three consecutive frequencies in less than 3 days.However,its pathogenesis is still unknown.Recent re-searches suggest that inflammation plays a very important role in its development and prognosis.For this reason,we reviewed the relationship between inflammation and SSNHL from the perspective of development and prognosis,and further discussed the role of inflammation in the pathogenesis of SSNHL.

In recent years,the global consumption of ultra-processed foods(UPFs)has increased.UPFs are classified as the fourth group of food in the NOVA classification system:industrially formulated foods made entirely or mostly from substances extracted from foods(oils,fats,sugar,starch,proteins,etc),derivatives of food constituents(hydrogenated fats,modified starches,etc),or multiple food additives.Common manufacturing techniques include extrusion,moulding,and pre-frying.As high-energy-density foods,UPFs are typically characterized by high levels of sugar,fat,and salt,and low levels of dietary fiber,protein,vitamins,and minerals,resulting in low nutrient density.Studies have shown that a high intake of UPFs increases the risk of various chronic diseases.Nutrition during pregnancy is a crucial factor influencing pregnancy outcomes,and balanced and adequate nutrient intake is essential for the health of both the mother and child.Given that UPFs have limited nutritional density,high intake during pregnancy may be detrimental to maternal and infant health.However,the impact of consuming UPFs during pregnancy on maternal and infant health is not extensively studied.This article reviews the literature on the effects of UPFs on pregnancy outcomes,aiming to provide a foundation for further research and personalized dietary guidance.

Objective:To explore the mediating role of negative automatic thoughts between health literacy and childbirth fear of primiparas.Methods:The primiparas who underwent obstetric examination in Department of Obstetrics, Lishui People′s Hospital from January 2021 to December 2023 were selected as the research objects by convenience sampling method. Using cross-sectional survey, the general information questionnaire, Childbirth Attitude Questionnaire, The Automatic Thought Questionnaire and Perinatal Pregnant Women′s Health Literacy Scale were used to investigate. Pearson correlation analysis was performed by SPSS 26.0, AMOS 24.0 was used to construct the mediating effect model of negative automatic thoughts between health literacy and childbirth fear of primiparas, and Bootstrap method was used to test the mediating effect.Results:A total of 246 questionnaires were distributed, and 235 valid questionnaires were collected. The age of 235 primiparas was (27.56 ± 3.74) years old. The total score of health literacy, negative automatic thoughts, childbirth fear was (173.29 ± 20.20), (88.13 ± 16.50), (46.52 ± 12.67) points. The direct effect of health literacy on childbirth fear of primiparas was -0.319 (95% CI -0.495--0.144), accounting for 56.00% of the total effect. The indirect effect of negative automatic thoughts between health literacy and childbirth fear was -0.251 (95% CI -0.393--0.127), accounting for 44.00% of the total effect. Conclusions:Negative automatic thoughts plays a partial mediating role between health literacy and childbirth fear of primiparas. Nursing staff should formulate intervention measures according to the path of influencing childbirth fear, so as to minimize the level of childbirth fear.
