This study explored the prescription pattern of traditional Chinese medicine(TCM) in the treatment of hypertensive left ventricular hypertrophy(LVH), so as to provide a relevant theoretical basis for the clinical diagnosis and treatment of hypertensive LVH. The study systematically searched the databases of CNKI, Wanfang, VIP, and SinoMed to screen out the qualified literature on TCM treatment of hypertensive LVH and used Microsoft Excel 2021 to establish the relevant prescription database. It also counted the frequency, property, flavor, and meridian affiliation of TCM in the prescriptions and classified their efficacy. The study used Lantern 5.0 and Rstudio software to analyze the hidden structural models and association rules of the high-frequency TCM with a frequency of >3.50% and adopted Origin 2024 software to visualize the data, so as to explore the prescription pattern of TCM in treating hypertensive LVH. The results showed that a total of 128 TCM prescriptions were included, involving 163 TCM with a total frequency of 1 242. The high-frequency TCM included Salviae Miltiorrhizae Radix et Rhizoma, Uncariae Ramulus Cum Uncis, Gastrodiae Rhizoma, Poria, and Chuanxiong Rhizoma, with the main efficacy from blood-activating and stasis-resolving herbs, tonic herbs, and liver-calming and wind-extinguishing herbs. The latent structure analysis(LSA) identified 10 latent variables, 20 latent classes, 7 comprehensive clustering models, and 23 core prescriptions. It was speculated that the common syndromes of hypertensive LVH included blood stasis obstructing the collaterals, ascending hyperactivity of liver Yang, Yin deficiency with Yang hyperactivity, and intermingled phlegm and blood stasis. The association rule analysis yielded 33 strong association rules, with the highest comprehensive association rule being Gastrodiae Rhizoma→Uncariae Ramulus Cum Uncis. Hypertensive LVH is characterized by asthenia in origin and asthenia in superficiality, with Yin deficiency and Qi deficiency as the origin and blood stasis and phlegm as the superficiality. Clinical treatment focuses on activating blood circulation, resolving stasis, tonifying Qi, and nourishing Yin, combined with syndrome-specific therapies such as calming wind and stopping convulsions, clearing heat, eliminating dampness and resolving phlegm, and promoting diuresis and reducing swelling.

OBJECTIVE To explore the characteristics and influential factors of pharmaceutical clinic service demands， providing evidence for optimizing pharmaceutical service models and facilitating pharmaceutical service models of pharmacist role transformation. METHODS A cross-sectional survey design was adopted， and 410 outpatient participants were selected from Fudan University Shanghai Cancer Center through convenience sampling for questionnaire administration from February to May 2025. Kano model was applied to analyze the demand attributes of 25 pharmaceutical services， while questionnaires were used to assess patients’ awareness and demand status. Subgroup analyses were conducted based on key demographic variables such as gender， age， educational attainment， and economic burdens， to SACA- systematically examine the differences in Kano attribute classification among patients in each subgroup. RESULTS The awareness rate of pharmaceutical outpatient services among patients was only 14.63%， yet those who were aware demonstrated a significantly higher demand rate for such services compared to those who were unaware （P＜0.001）. The demand for pharmaceutical clinic services exhibited a hierarchical characteristic： twelve items were identified as attractive attributes （e. g.， providing suggestions for more affordable treatment options， offering online consultation services， etc.）， five items as expected attributes （e.g.， having a good attitude and being able to patiently answer your questions， etc.）， three items as must-have attributes （e.g.， providing guidance on medication dosage and usage， providing guidance on medication precautions， etc.）， five items as indifferent attributes （e.g.， providing treatment plan recommendations based on the patient’s condition）. There were zero items classified as reverse attribute. Subgroup analysis revealed that female patients showed greater concern for “neat and clean attire of medical staff” than male patients （P＜0.001）； patients under 60 years of age demonstrated stronger demand for “providing treatment plan recommendations based on patients’ conditions” compared to patients aged 60 or above （P＝0.016）； those with below high school education placed greater emphasis on “providing guidance on medication precautions” compared to those with a high school education or above （P＝0.011）； patients with lower economic burdens exhibited stronger preferences for “neat and clean attire of medical staff ” （P＝0.002）. CONCLUSIONS The public awareness rate of pharmaceutical clinic services is considerably low； however， those who are aware of such services demonstrate significantly higher demand. The medication safety-related services and convenience-oriented demands should be prioritized in the development of pharmaceutical clinics. Moreover， the study also revealed that factors such as gender， age， educational level， and economic burdens exert significant influences on patients’ service demands.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To evaluate the clinical effect of derotational distal femoral osteotomy (DDFO) combined with medial patellofemoral ligament (MPFL) reconstruction assisted by digital orthopedic technique in the treatment of recurrent patellar dislocation with enlarged femoral anteversion angle (FAA).Methods:TThe clinical data of 18 patients (4 men and 14 women; mean age 22.1±0.7 years; range, 18-26 years) with recurrent patellar dislocation (FAA≥30°) admitted to Digital Orthopedic Technology Clinical Application Center in Tianjin hospital from May 2022 to December 2023 were retrospectively analyzed. The average number of patella dislocations were 3.6±0.4 (range, 2-8 times), with a mean symptom duration of 4.3±0.4 years (range, 2-7 years). According to Dejour classification of femoral trochlea dysplasia, there were 5 cases of type A, 3 cases of type B, 6 cases of type C and 4 cases of type D. All patients underwent 3D CT scanning and digital modeling before operation. Based on the modeling results, personalized osteotomy and orthopedic integration guide were designed and printed to direct intraoperative DDFO and MPFL reconstruction. Radiological parameters, knee function and complications were assessed during follow-up. Knee function assessments included visual analogue scale (VAS), Intemational Knee Documentation Committee Knee Form (IKDC), Kujala, Lysholm and Tegner score. The radiological parameters included FAA, patellar tilt angle (PTA), tibial tuberosity-trochlear groove distance (TT-TG) and caton-deschamps index (CDI).Results:All patients underwent surgery and were followed up for 15.4±2.8 months (range, 12-20 months). Complications occurred in 3 patients, including deep venous thrombosis in 2 cases and wound effusion in 1 case. No other complications such as wound infection, nerve injury, vascular injury, fracture nonunion or patella dislocation were recorded. The VAS score improved from 5.4±0.3 preoperatively to 2.1±0.2 at one year postoperatively. The IKDC score improved from 44.4±2.7 to 79.2±1.9 points. The Kujala score improved from 51.8±2.6 to 86.1±1.6, the Lysholm from 49.8±2.5 to 84.9±1.5, and the Tegner score from 2.2±0.2 to 4.1±0.2. The FAA decreased from 39.7°±1.2° to 14.9°±0.2°, the PTA from 33.1°±2.6° to 12.6°±1.4°, and the TT-TG from 20.2±0.6 to 13.9±0.4 mm. The differences between time of all the above-mentioned parameters were statistically significant ( P<0.05). The CDI remained stable, which changed from 1.03±0.02 preoperatively to 1.07±0.01 one year after operation ( P>0.05). Conclusions:After the application of DDFO combined with MPFL reconstruction assist by personalized osteotomy and orthopedic integrated guide, the patient's knee function and imaging parameters were significantly improved at one-year follow-up. In the treatment of recurrent patellar dislocation with enlarged FAA, good early clinical efficacy could be achieved with this operation.

In-depth study of the components of polymyxins is the key to controlling the quality of this class of antibiotics.Similarities and variations of components present significant analytical challenges.A two-dimensional(2D)liquid chromatography-mass spectrometry(LC-MS)method was established for screening and comprehensive profiling of compositions of the antibiotic colistimethate sodium(CMS).A high concentration of phosphate buffer mobile phase was used in the first-dimensional LC system to get the components well separated.For efficient and high-accuracy screening of CMS,a targeted method based on a self-constructed high resolution(HR)mass spectrum database of CMS components was established.The database was built based on the commercial MassHunter Personal Compound Database and Library(PCDL)software and its accuracy of the compound matching result was verified with six known components before being applied to genuine sample screening.On this basis,the unknown peaks in the CMS chromatograms were deduced and assigned.The molecular formula,group composition,and origins of a total of 99 compounds,of which the combined area percentage accounted for more than 95％of CMS components,were deduced by this 2D-LC-MS method combined with the MassHunter PCDL.This profiling method was highly efficient and could distinguish hundreds of components within 3 h,providing reliable results for quality control of this kind of complex drugs.

Objective To explore the association between nocturnal blood pressure decline rate and chronic heart failure(CHF).Methods In this study,a total of 711 individuals who underwent 24-h ambulatory blood pressure monitoring were divided into control group(n=433)and CHF group(n=278).The characteristics of the study population and nocturnal blood pressure decline rate were compared between CHF group and control group.Restricted spline analysis was utilized to examine the linear or non-linear association between nocturnal blood pressure decline rate and the prevalence of CHF.The relationship between nocturnal blood pressure decline rate and CHF was further investigated based on multivariable Logistic regression model.Results Nocturnal systolic blood pressure decline rate was significantly different in CHF group and control group[(3.3±7.1)mmHg vs.(5.0+6.7)mmHg,P=0.001].No significant difference in nocturnal diastolic blood pressure was found between the two groups[(5.7±7.6)mmHg vs.(6.8±7.2)mmHg,P=0.061].Restricted spline analysis showed a significant linear association between nocturnal systolic blood pressure decline rate and CHF risk.After adjusting for age,sex,smoking,body mass index,24-hour systolic blood pressure,24-hour diastolic blood pressure,type 2 diabetes mellitus and hyperlipidemia,multivariate Logistic regression analysis revealed that nocturnal systolic blood pressure decline rate was negatively associated with the prevalence of CHF(OR=0.97,95％CI:0.95-0.99;P=0.010).However,no significant association was found between nocturnal diastolic blood pressure decline rate and CHF risk.Conclusion Nocturnal systolic blood pressure decline rate is associated with the prevalence of CHF.Individuals with decreased nocturnal systolic blood pressure decline have a significantly increased risk of CHF.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.
