OBJECTIVE To investigate the effectiveness of resident clinical pharmacist-led medication therapy management （MTM） model in geriatric cardiology departments， and provide reference for optimizing resident pharmaceutical services. METHODS A retrospective cohort study was conducted， incorporating data from inpatients admitted to the Department of Cardiovascular Medicine in the Geriatric Medical Center of our hospital during March to August 2023 （conventional group， n＝ 903） and the same period in 2024 （MTM group， n＝963）. The conventional group received only standard pharmaceutical services （including prospective prescription review and retrospective order evaluation）， while the MTM group received additional resident clinical pharmacist-led interventions-such as medication reconciliation， personalized therapeutic drug monitoring （TDM）， standardized intravenous infusion management， and a four-stage closed-loop monitoring process-based on conventional care. The effectiveness of the MTM model was evaluated by comparing the primary outcome measures （e.g.， intravenous infusion rate， TDM target attainment rate） and secondary outcome measures [e.g.， incidence of drug-drug interactions （DDIs）， incidence of grade 3 or higher acute kidney injury， average length of hospital stay， cholesterol， and medication cost per capita] between the two groups. RESULTS Compared with the conventional group， in terms of primary outcome indexes： both the overall intravenous infusion rate and the use rate of acid-suppressive injection were significantly lowered in the MTM group （P＜0.05）； serum concentration target attainment rates for digoxin and vancomycin were increased significantly （P＜0.05）. For secondary outcome indexes， the MTM group exhibited significant decreases in the work incidence of grade 3 or higher acute kidney injury， the incidence of DDIs， the rate of patients leaving the hospital against medical advice， alanine amino-transferase， aspartate transferase and the per capita total medication cost （P＜0.05）. Additionally， there was a notable increase in the creatinine， estimated glomerular filtration rate and a significant shortening of the per capita length of hospital stay （P＜0.05）. CONCLUSIONS The resident clinical pharmacist-led MTM model can significantly optimize medication therapy processes， enhance medication safety and cost-effectiveness， thus playing a positive role in promoting rational drug use and improving patient outcomes.

Objective:To study the application effect of the Benner's theory stratified training based on the "Protect the World" platform for nurses specialized in neurological rehabilitation.Methods:A total of 70 nurses who underwent on-the-job training for neurorehabilitation nursing specialists in 2023 were divided into control group ( n=35) and observation group ( n=35) based on random odd and even numbers to receive different training methods. The control group received routine nursing training, while the observation group received Benner's theory stratified training based on the "Protect the World" platform. The theoretical and skill assessment scores, job competency, and satisfaction scores of two groups of nurses were compared before and after training. SPSS 25.0 was used for t-test and chi-square test. Results:Before training, there were no significant differences between the two groups of nurses in terms of theory scores [(88.35±4.41) vs. (89.43±4.07)] and skill assessment scores [(89.22±3.27) vs. (88.43±3.16)]. After training, the theoretical and skill assessment scores were significantly higher in the observation group as compared with the control group [(95.51±5.01) vs. (90.24±4.99) and (95.15±4.24) vs. (91.13±4.33), both P<0.05]. After training, the competency scores and total scores of education guidance, management function, diagnostic function, assistance role, and intervention treatment were significantly higher in the observation group than in the control group ( P<0.05). The satisfaction survey scores were significantly higher in the observation group than in the control group ( P<0.05). Conclusions:The Benner's theory stratified training based on the "Protect the World" platform can improve the theoretical and skill assessment scores of nurses specialized in neurological rehabilitation. This approach significantly boosts their overall professional competence and holds considerable potential for broader adoption.

Objective To explore the safety and feasibility of laparoscopic surgery for congenital annular pancreas in neonates.Methods From June 2015 to June 2023,a total of 61 neonates with congenital annular pancreas were treated with three-port laparoscopic surgery.Under the laparoscope,the proximal and distal segments of the duodenum around the annular pancreas were freed.The duodenum was then suspended,and a transverse incision was made in the dilated proximal duodenum while a longitudinal incision was made in the narrowed distal part.Continuous suturing of the anterior and posterior walls of the duodenum was performed with 5-0 PDS sutures.Results Three cases were converted to open surgery,while the remaining 58 cases were completed under laparoscope.The duration of surgery ranged 60-324 min,with an average of(163±57)min.The time to start oral feeding after surgery ranged 3-15 d,with an average of(6.8±2.9)d.The length of hospital stay varied 4-83 d,with a median of 17 d.One case experienced intestinal adhesive obstruction at 12 d after surgery,and underwent laparoscopic adhesion release.One case developed anastomotic leakage at 3 d after surgery and underwent laparoscopic repair.One case with prematurity and low birth weight developed severe infection,shock,and disseminated intravascular coagulation at 73 d after surgery,and died after the family decided to discontinue treatment.The remaining 60 cases were discharged after successful treatment.All the 60 patients were regularly followed up for 1-96 months,with a median of 37 months,having a good growth and development.Conclusions Laparoscopic surgery in the treatment of congenital annular pancreas in neonates is safe and feasible.Refined management is required during the perioperative period for premature and low birth weight infants.

The course, progression, and prognosis of fetal congenital cystic adenomatoid malformation (CCAM) depend on the size of the mass, whether the mediastinum is displaced, changes in fetal hemodynamics, and the occurrence of fetal hydrops, with large CCAM being relatively rare. In this case, a fetus was suspected of having a large CCAM with fetal hydrops and cardiac insufficiency at 27 weeks of gestation. After multiple imaging evaluations and multidisciplinary consultations, a delivery plan and neonatal resuscitation plan were formulated. At 31 +4 weeks of gestation, in-utero thoracentesis and drainage were performed. Postoperatively, the fetal CCAM was reduced compared to before, and the maternal symptoms of chest tightness and shortness of breath were also improved. Three days after the procedure, the mother experienced premature rupture of membranes and delivered a male infant vaginally at 32 weeks of gestation. On the fifth day after birth, the newborn underwent resection of the pulmonary cystic adenomatoid malformation, confirming the diagnosis. Follow-up for two years post-birth showed good prognosis for both the mother and the child. Therefore, when CCAM is detected during pregnancy, thorough in-utero evaluation should be conducted, and a monitoring plan should be developed based on potential perinatal conditions to avoid unnecessary termination of pregnancy. If the pregnancy continues, multidisciplinary evaluation and preparation for perinatal surgery are necessary.

Objective:To summarize the clinical features of primary segmental volvulus (PSV) in neonates.Methods:A retrospective analysis was conducted on the clinical data of neonates with PSV who were admitted to the Department of Neonatal Surgery, Children's Hospital Affiliated to Capital Institute of Pediatrics from May 2014 to May 2023. The clinical manifestations, auxiliary examinations, treatment and prognosis of the neonates were summarized, and descriptive statistical analysis was performed on the collected data.Results:A total of 10 neonates with PSV were included, with a mean gestational age of (34.1±3.0) weeks and birth weight of (2 291±646) g. Eight cases had an onset age of 3 d or less, and 2 cases had an onset age of more than 3 d. Abdominal distension was observed as the main manifestation in all cases, while bilious vomiting occurred in seven cases and hematochezia in five cases. Imaging examinations mainly revealed low intestinal obstruction without specific manifestations. Laboratory tests showed metabolic acidosis and varing degrees of anaemia. Nine cases underwent diagnostic abdominal puncture, of which five had bloody ascites, two had clear ascites, one had bloody mixed with fecal-like ascites, and one had chylous ascites. All the cases underwent emergency exploratory laparotomy and segmental small bowel resections with either primary intestinal anastomosis or enterostomy. All cases were successfully cured and had been followed up to the age of 4 months to 9 years with good growth and development as normal children of the same age.Conclusions:Neonatal PSV is an independent abdominal emergency characterized by non-specific clinical manifestations and difficult preoperative diagnosis, but the overall prognosis is favorable after active surgical treatment.

Atherosclerosis is a chronic vascular inflammatory disease caused by abnormal lipid metabolism.The formation of lipid-rich foam cells acts as the initial trigger for development of atherosclerotic lesions.Recent studies have shown that lipophagy,a form of selective autophagy,can selectively degrade lipid droplets stored intracellularly and promote cholesterol efflux through the autophagic lysosomal pathway.As a result,intracellular lipid accumulation is re-duced and foaming is inhibited,making lipophagy a potential new target for current anti-atherosclerosis therapy.This arti-cle reviews the crucial role and molecular mechanism of lipophagy in the link between lipid metabolism and atherosclero-sis.Its objective is to outline the regulatory mechanism of lipophagy and present fresh insights for the treatment of athero-sclerotic diseases.

OBJECTIVE To establish an HPLC method for the separation of enantiomers of farrerol, and apply it to the determination of the content of enantiomers in Rhododendri Daurici Folium and Rhododendron Micranthum. METHODS HPLC was used to separate the farrerol enantiomers, and the chromatographic conditions of chiral column type, mobile phase ratio, flow rate, and column temperature were optimized. The thermodynamic separation of farrerol enantiomers was discussed. Thermodynamic parameters such as enthalpy change, entropy change, enthalpy change and entropy change were calculated. And the contents of two enantiomers in Rhododendri Daurici Folium and Rhododendron Micranthum were determined under the optimum resolution conditions. RESULTS The optimum separation conditions for two enantiomers of farrerol were determined as follows: Chiralcel OJ-RH(4.6 mm×150 mm, 5 μm), equilibrium elution of acetonitrile-water(40∶60), the flow rate of 0.5 mL·min–1, the column temperature of 25 ℃, and the detection wavelength of 295 nm. Under the optimum separation conditions, the resolution of farrerol enantiomers reached 1.5, indicating that the two enantiomers of the farrerol could be completely separated. When the column temperature was between 20 ℃ and 35 ℃, the separation factor decreased with the increase of temperature. The lnα of the two enantiomers of farrerol showed a good linear relationship with 1/T, and the chiral reselution process was controlled by enthalpy. The enantiomer separation method of farrerol was applied to the determination of farrerol enantiomer in Chinese medicinal materials of Rhododendri Daurici Folium and Rhododendron Micranthum. The linear relationship between the two enantiomers of farrerol were good in the range of 0.718–57.44 μg·mL–1 and 1.28–102.24 μg·mL–1, respectively. And the contents of the two enantiomers of farrerol in Rhododendri Daurici Folium were 0.228 2 and 0.466 2 mg·g–1, respectively. And the contents of the two enantiomers of farrerol in Rhododendron Micranthum were 0.416 8 and 0.707 3 mg·g–1, respectively. CONCLUSION This method is simple, efficient and suitable for the determination of farrerol enantiomers in traditional Chinese medicine.

Objective:To explore the risk factors of sepsis in patients with multiple trauma and construct a nomogram prediction model.Methods:The data of patients with multiple injuries admitted to the emergency intensive care unit (EICU) of the General Hospital of Ningxia Medical University from January 2021 to April 2022 were respectively collected. Inclusion criteria: (1) meet the diagnostic criteria for multiple injuries; (2) the time from injury to admission ≤ 24 hours; (3) age>18 years old; (4) all examination or rescue measures were approved by the patient or the patient's family; (5) the patient's clinical data were complete. The patients were divided into sepsis group and non-sepsis group according to the definition of Sepsis 3.0 at the 28-day of EICU hospitalization. The receiver operating characteristic curve was drawn. Logistic regression analysis was applied to determine the independent predictors for sepsis, and the nomogram was constructed.Results:A total of 291 patients were included, including 102 in the sepsis group and 189 in the non-sepsis group. Multivariate logistic analysis revealed that age, acute physiology and chronic health status score (APACHE) Ⅱ, Glasgow Coma Scale (GCS), injury severity score (ISS), sequential organ failure assessment (SOFA) within 24 hours after admission, blood transfusion frequency, the application of norepinephrine, mechanical ventilation, pathogenic culture results, and history of diabetes were independent factors influencing the occurrence of sepsis. A nomogram model was constructed by combining these variables (AUC=0.913, 95% CI: 0.847-0.942), and the model had a good fitting calibration curve. Conclusions:The nomogram constructed by age, APACHE-Ⅱ, GCS score, SOFA score, ISS score, number of blood transfusions, mechanical ventilation, norepinephrine drug use, pathogenic culture and diabetes has a good predictive value for sepsis in patients with multiple trauma in the later stage, which is worth promoting.

This study was designed to evaluate the effect and mechanism of mitogen-activated protein kinase(MAPK)activated protein kinase 2(MK2)in Angiotensin Ⅱ(AngⅡ)-induced mouse renal damage.Total of 16 wild type C57BL/6J mice were randomly divided into MK2+/+control group and MK2+/++AngⅡ group,while 16 MK2 knockout C57BL/6J mice were randomly divided into MK2-/-control group and MK2-/-+AngⅡ group.Kidney damage was induced by subcutaneous injection of AngⅡ for 4 weeks.Then corresponding methods were carried out to detect systolic pressure,serum creatinine,24h urinary albumin,glomerulosclerosis index,renal tubulointerstitial injury score,the expression level of phosphorylated MK2(p-MK2),p-p65 nuclear factor-κB(NF-κB),the contents of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),reactive oxygen species(ROS),superoxide dismutase(SOD)and malondialdehyde(MDA).Compared with the MK2+/+control group,MK2+/++AngⅡ group demonstrated significant increase in systolic blood pressure,serum creatinine,24h urinary albumin,glomerulosclerosis index,renal tubulointerstitial injury score,the expression levels of p-MK2,p-p65 NF-κB expression,and the contents of TNF-α,IL-6,ROS,MDA,while significant decrease in the level of SOD in kidney(P<0.05).Compared with the MK2+/++AngⅡ group,MK2-/-+AngⅡ group showed no significant difference in systolic blood pressure(P>0.05),significant decrease in the serum creatinine,24 h urinary albumin,glomerulosclerosis index,renal tubulointerstitial injury score,the expression levels of p-MK2,p-p65 NF-κB and the contents of TNF-α,IL-6,ROS,MDA,while significant increase in the content of SOD in kidney(P<0.05).In conclusion,MK2 knockout significantly alleviates AngⅡ-induced renal damage and inhibits inflammatory and oxidative stress responses.MK2 is involved in AngⅡ induced renal damage.

Objective:To explore the dosimetry difference between intensity-modulated radiotherapy (IMRT) and volumetric intensity modulated arc therapy (VMAT) based on the inner edge tangent field (IETF) after left-sided breast conserving surgery.Methods:The localization CT and target organ at risk (OAR) data of 35 patients with left-sided breast cancer treated with IMRT after breast conserving surgery at Department of Radiotherapy in Yunnan Cancer Hospital from June 2022 to June 2023 were selected. The IETF-IMRT and the IETF-VMAT plans were designed for the same patient based on IETF, the dosimetry differences of target areas and OAR, as well as the planned execution time were compared between the two groups.Results:Dosimetry of target areas: for IETF-IMRT and IETF-VMAT, the D 98% of the planning target volume were (47.92±0.51) and (48.21±0.33) Gy, respectively, while the D 50% were (52.04±0.22) and (51.91±0.26) Gy, respectively, and the D 2% were (53.93±0.36) and (53.62±0.41) Gy, respectively, the conformity index were 0.84±0.03 and 0.87±0.02, respectively, while the homogeneity index were 0.12±0.01 and 0.10±0.01, respectively, with statistically significant differences ( t=-3.87, P<0.001; t=3.53, P=0.001; t=5.30, P<0.001; t=-13.60, P<0.001; t=6.24, P<0.001). Dosimetry of OAR: for IETF-IMRT and IETF-VMAT, the left lung V 5 were (31.91±6.28) % and (33.99±6.31) %, respectively, and the V 20 were (11.71±2.06) % and (9.73±2.12) %, respectively, with statistically significant differences ( t=-4.18, P<0.001; t=12.40, P<0.001). The right lung V 5 were (0.11±0.08) % and (7.13±3.12) %, respectively, and the D mean were (1.05±0.12) and (2.71±0.27) Gy, respectively, with statistically significant differences ( t=-33.62, P<0.001; t=-13.30, P<0.001). The spinal cord D 2% were (1.08±0.11) and (4.83±1.40) Gy, respectively, with a statistically significant difference ( t=-15.99, P<0.001). The left lung D mean were (7.45±1.08) and (7.37±1.03) Gy, the heart D mean were (4.21±0.96) and (4.41±0.48) Gy, and the right-sided breast D mean were (3.74±1.52) and (3.48±1.11) Gy, respectively, with no statistically significant difference ( t=1.16, P=0.253; t=-1.76, P=0.088; t=1.41, P=0.169). Planned execution time: the execution time of IETF-IMRT and IETF-VMAT was (10.73±1.21) and (2.18±0.17) min, respectively, with a statistically significant difference ( t=44.71, P<0.001) . Conclusion:Both IETF-IMRT and IETF-VMAT can meet clinical requirements, however the two techniques have their own characteristics. IETF-VMAT has better conformity and homogeneity of target region. The planned OAR dosimetry in both plans are significantly lower than the dose limit of postoperative radiotherapy for breast cancer, among which the left lung V 5, the right lung V 5, D mean and spinal cord D 2% of IETF-IMRT are slightly lower, the left lung V 20 of IETF-VMAT is slightly lower. IETF-VMAT significantly reduces the planned execution time compared with IETF-IMRT, thus can greatly reduce the dose deviation caused by patient position change, and significantly improve patients experience and comfort of radiotherapy. Taken together, IETF-VMAT has advantages over IETF-IMRT in radiotherapy after breast conserving surgery of left-sided breast cancer.
