With the rising prevalence of chronic diseases and an aging population,China's traditional segmented health-care delivery model is increasingly inadequate for meeting the growing demand for long-term,systematic health management.In response,the"Physician-Pharmacist Co-management"model has emerged,aiming to enhance the quality and continuity of care through close collaboration between physicians and pharmacists.This paper starts from the concept and origin of"Physician-Phar-macist Co-management"model,focusing on its China-specific advantages shaped by national healthcare policies and clinical real-ities.Unlike the internationally recognized Collaborative Drug Therapy Management(CDTM)model,the Chinese approach re-flects local healthcare structures and needs.Using obstructive pulmonary disease(COPD)as a case study,we examine the mod-el's application and value in managing chronic respiratory diseases.Data indicate that,after the implementation of"physician-pharmacist co-management"model in COPD patients,the CAT score decreased by approximately 24％,the annual rate of acute exacerbation-related hospitalizations declined by about 72％,and the proportion of patients with regular pulmonary rehabilitation exercise habits increased by roughly 3.3-fold.Additionally,the percentage of patients without adverse reactions rose from 47.37％to 64.41％,and the vaccination rate increased by about 2.7-fold.These findings demonstrate the model's significant advantages in improving clinical outcomes,enhancing patient adherence,and reducing healthcare costs.Despite benefits,howev-er,the"Physician-Pharmacist Co-management"model in China faces several challenges,including limited public awareness,gaps in pharmacist training,and insufficient policy support.To address these challenges,this study recommends strengthening public education,establishing comprehensive evaluation systems for pharmaceutical professionals,and improving incentive mech-anisms.Overall,the findings suggest that the"Physician-Pharmacist Co-management"model holds considerable promise for im-proving the quality of chronic disease management,enhancing patient adherence,and optimizing healthcare resource utilization in China.

Objective To evaluate the optimal traction amount for treating scoliosis using halo pelvic ring traction(HPRT)and provide theoretical references for clinical surgical assessment and rehabilitation.Methods A three-dimensional(3D)model of the thoracolumbar spine including the spinal cord was created and validated.Five traction amounts(10,15,20,25,30 mm)were applied to the model.The biomechanical responses of the spine under different traction conditions were simulated to determine the optimal amount of traction.Results As the traction increased,the Cobb angle decreased progressively.Significantly,in the range of 15-20 mm,the reduction in Cobb angle accounted for 50%-70.5%of the maximum reduction.The spinal stress at the main curvature represented 47.4%-67.5%of the maximum stress.Meanwhile,the stresses in the gray and white matter of the spinal cord were 70.3%-84.5%and 68.8%-83.9%of their respective maximum stresses.Conclusions The traction amounts between 15 mm and 20 mm are optimal for treating scoliosis.This range maximizes the Cobb angle correction while maintaining lower stress levels and thereby,reduces the risk of damage to the spine and spinal cord.

Background and objective Neoantigen reactive T cell(NRT)has the ability to inhibit the growth of tumors expressing specific neoantigens.However,due to the difficult immune infiltration and the inhibition of tumor micro en-vironment,the therapeutic effect of NRT in solid tumors is limited.In this study,we designed NRT cells(7×19 NRT)that can express both interleukin-7(IL-7)and chemokine C-C motif ligand 19(CCL19)in mouse lung cancer cells,and evaluated the difference in anti-tumor effect between 7×19 NRT cells and conventional NRT cells.Methods We performed next-generation sequencing and neoantigen prediction for mouse Lewis lung carcinoma(LLC),prepared RNA vaccine,cultured NRT cells,constructed retroviral vectors encoding IL-7 and CCL19,transduced NRT cells and IL-7 and CCL19 were successfully ex-pressed,and 7×19 NRT was successfully obtained.The anti-tumor effect was evaluated in vivo and in vitro in mice.Results The 7×19 NRT cells significantly enhanced the proliferation and invasion ability of T cells by secreting IL-7 and CCL19,achieved significant tumor inhibition in the mouse lung cancer and extended the survival period of mice.The T cell infiltration into tumor tissue and the necrosis of tumor tissue increased significantly after 7×19 NRT treatment.In addition,both 7×19 NRT treatment and conventional NRT treatment were safe.Conclusion The anti-solid tumor ability of NRT cells is significantly enhanced by the arming of IL-7 and CCL19,which is a safe and effective genetic modification of NRT.

To investigate the effects of postoperative fusion implantation on the mesoscopic biomechanical properties of vertebrae and bone tissue osteogenesis in idiopathic scoliosis, a macroscopic finite element model of the postoperative fusion device was developed, and a mesoscopic model of the bone unit was developed using the Saint Venant sub-model approach. To simulate human physiological conditions, the differences in biomechanical properties between macroscopic cortical bone and mesoscopic bone units under the same boundary conditions were studied, and the effects of fusion implantation on bone tissue growth at the mesoscopic scale were analyzed. The results showed that the stresses in the mesoscopic structure of the lumbar spine increased compared to the macroscopic structure, and the mesoscopic stress in this case is 2.606 to 5.958 times of the macroscopic stress; the stresses in the upper bone unit of the fusion device were greater than those in the lower part; the average stresses in the upper vertebral body end surfaces were ranked in the order of right, left, posterior and anterior; the stresses in the lower vertebral body were ranked in the order of left, posterior, right and anterior; and rotation was the condition with the greatest stress value in the bone unit. It is hypothesized that bone tissue osteogenesis is better on the upper face of the fusion than on the lower face, and that bone tissue growth rate on the upper face is in the order of right, left, posterior, and anterior; while on the lower face, it is in the order of left, posterior, right, and anterior; and that patients' constant rotational movements after surgery is conducive to bone growth. The results of the study may provide a theoretical basis for the design of surgical protocols and optimization of fusion devices for idiopathic scoliosis.

Background: Patients with functional dyspepsia (FD) are accompanied by different degree of psychological stress, and clinicians usually have insufficient quantitative assessment of patients’psychological stress. Aims: To explore the effect of psychological stress assessed by 4-item perceived stress scale (PSS-4) and 10-item perceived stress scale (PSS-10) on dyspepsia symptoms, anxiety, depression, somatization and quality of life in FD patients. Methods: A total of 357 FD patients met Rome IV criteria from March 2021 to March 2022 at Affiliated Hospital of North Sichuan Medical College were recruited. Score of PSS-4, PSS-10, generalized anxiety disorder-7 (GAD-7), patient healthy questionnaire-9 (PHQ-9), adapted patient healthy questionnaire-15 (adapted PHQ-15), dyspepsia symptom severity (DSS), Nepean dyspepsia index-short form (NDI) were performed. Effects of PSS-4, PSS-10 on dyspepsia symptoms, anxiety, depression, somatization and quality of life in FD patients were analyzed. Results: Correlation analysis showed that PSS-4 (r=0.152, P=0.004) and PSS-10 (r=0.194, P=0.000) were correlated with DSS; PSS-4 (r=0.341, P=0.000) and PSS-10 (r=0.389, P=0.000) were correlated with adapted PHQ-15; PSS-4 (r=0.239, P=0.000) and PSS-10 (r=0.327, P=0.000) were correlated with NDI; PSS-4 (r= 0.561, P=0.000) and PSS-10 (r=0.680, P=0.000) were correlated with anxiety; PSS-4 (r=0.449, P=0.000) and PSS-10 (r= 0.524, P=0.000) were correlated with depression. Multiple linear regression analysis showed that psychological stress assessed by PSS-4 (β=0.180, P=0.000), DSS (β=0.390, P=0.000) and FD classification (β=-0.116, P=0.024) were the influencing factors of NDI, and the psychological stress assessed by PSS-10 (β=0.268, P=0.000), DSS (β=0.360, P=0.000) and FD classification (β=-0.116, P=0.021) were the influencing factors of NDI. Conclusions: Psychological stress assessed by PSS-4, PSS-10 have effects on anxiety, depression, somatization, DSS and NDI in FD patients, and PSS-4 is shorter. These results suggest that PSS-4 can be used clinically to assess quickly and initially the impact of psychological stress on FD patients.

Objective:To investigate the characteristics of newly diagnosed patients with chronic obstructive pulmonary disease (COPD) in Shenzhen primary care.Methods:Random sampling was conducted in 10 jurisdictions of Shenzhen, permanent residents who were over 40 years old and lived for more than 6 months were included for lung function test, COPD Population Screener (COPD-PS) questionnaire and information survey, the prevalence of COPD was estimated, and statistical comparison was made between the two groups of subjects with newly diagnosed and previously diagnosed COPD.Results:Among 3 916 subjects, 3 591 had completed the whole screening process. The results showed that 280 COPD patients were diagnosed and the estimated standardized prevalence of COPD was 5.92% (95% CI: 4.05-8.34). Among them, 251 (89.64%) were newly diagnosed COPD patients and 29 (10.36%) were previously diagnosed COPD patients. Compared with previously diagnosed COPD, the proportion of female in the newly diagnosed COPD was higher (50.20% vs 10.34%, P<0.001), educational level in the newly diagnosed COPD was lower (the proportion of primary school and below was higher, 42.23% vs 20.69%, P=0.023), the proportion of those with frequent wheezing symptoms in the newly diagnosed COPD was lower (4.78% vs 51.72%, P<0.001), the proportion of those with mild degree of airway obstruction (GOLD 1) in the newly diagnosed COPD was higher (81.67% vs 20.69%, P<0.001). The detection rates of COPD-PS in newly diagnosed COPD and previously diagnosed COPD were 43.03% and 41.38% respectively. The area under the receiver operating characteristic curve of COPD-PS was 0.705. Conclusion:The phenomenon of insufficient diagnosis of COPD in Shenzhen primary care is common and we should vigorously popularize pulmonary function examination.

Objective:To improve accuracy of prediction amount of length of gastric tube placed through nose and reduce occurrence of adverse events thorough clinical observation of measurement of length of nasogastric tube placement in critically ill children.Methods:Using the convenient sampling method, critically ill children who were hospitalized and needed a nasogastric tube in Pediatric Intensive Care Unit (PICU) of Beijing Children's Hospital Affiliated to Capital Medical University were selected from April to September 2019. The prediction method of "nos-ear-xiphoid (NEX) increased by 5 cm" (NEX+5 cm) was adopted. The values of placed length in this study were collected and compared with those predicted by traditional measurement method (namely NEX) , improved "nose-ear-mid-umbilicus" (NEMU) and formula method.Results:A total of 52 critically ill children were enrolled in this study. The length of placed nasogastric tube was 31.5 (28.3, 35.8) cm, and 43 cases (82.7%) were determined to be qualified by X-ray. The length of gastric tube required to be placed in children was 27.0 (24.1, 31.0) cm according to the NEX method, and the length of gastric tube required to be placed in children was 26.1 (22.5, 29.0) cm measured by the formula method. Both were shorter than that measured by NEX+5 cm, and the differences were statistically significant ( P<0.01) . The NEMU method measured the length of gastric tube to be inserted into the child to be 31.0 (28.3, 36.0) cm. Compared with the length measured by NEX+5 cm, and the difference was not statistically significant ( P>0.05) . Conclusions:This study uses NEX+5 cm to predict the actual length of the gastric tube inserted through the nose. The accuracy is relatively high and the operation method is simple. It is necessary to consider individual differences in clinical applications, especially the large variability in infants and young children. After catheterization, abdominal ultrasound, X-ray and other auxiliary examination methods should be used to determine the location of catheterization, and individualized catheterization programs should be given to children according to different therapeutic objective.
