OBJECTIVE To establish a “BRAND” pharmaceutical care model for advanced non-small cell lung cancer （NSCLC） patients with positive driver genes， providing theoretical and practical references for the clinical implementation of precise and individualized oncology pharmaceutical care. METHODS One hundred patients admitted to the department of pulmonary and critical care medicine in our hospital from January 2023 to May 2024 were collected meeting the inclusion and exclusion criteria. Patients were randomly divided into control group and intervention group， with 50 patients in each group. The control group received routine pharmaceutical care， while the intervention group received pharmaceutical care under the “BRAND” model （collecting patients’ basic information， reviewing disease treatment-related information， conducting precise medication assessments， formulating individualized pharmaceutical care plans for the next steps， and implementing medication guidance and follow-up management）. The study was conducted in a 3-week cycle for a total of 4 cycles. The medication compliance， quality of life， laboratory test indicators， incidence of drug-related adverse events and satisfaction of patients in both groups were compared before and after the intervention to evaluate the effects. RESULTS After 12 weeks of intervention， compared with the control group， the medication compliance， cognitive function， social function and satisfaction of patients in the intervention group were improved significantly （ P ＜0.05）； the severity of fatigue and constipation and the incidence of drug-related adverse events were significantly reduced （ P ＜0.05）， and there was no statistically significant difference in laboratory test indicators （ P ＞0.05）. CONCLUSIONS The “BRAND” pharmaceutical care model can effectively improve the medication compliance of patients with advanced NSCLC with positive driver genes and improve their quality of life. This study can provide a feasible path for clinical pharmacists to carry out standardized and high-quality pharmaceutical care.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

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 spectrometr (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 examine the mechanistic of organochlorine-associated changes in lung function. METHODS: This study investigated 76 healthy older adults in Jinan, Shandong Province, over a five-month period. Personal exposure to organochlorines was quantified using wearable passive samplers, while inflammatory factors and thyroid hormones were analyzed from blood samples. Participants' lung function was evaluated. After stratifying participants according to their thyroid hormone levels, we analyzed the differential effects of organochlorine exposure on lung function and inflammatory factors across the low and high thyroid hormone groups. Mediation analysis was further conducted to elucidate the relationships among organochlorine exposures, inflammatory factors, and lung function. RESULTS: Bis (2-chloro-1-methylethyl) ether (BCIE), was negatively associated with forced vital capacity (FVC, -2.05%, 95% CI: -3.11% to -0.97%), and associated with changes in inflammatory factors such as interleukin (IL)-2, IL-7, IL-8, and IL-13 in the low thyroid hormone group. The mediation analysis indicated a mediating effect of IL-2 (15.63%, 95% CI: 0.91% to 44.64%) and IL-13 (13.94%, 95% CI: 0.52% to 41.07%) in the association between BCIE exposure and FVC. CONCLUSION Lung function and inflammatory factors exhibited an increased sensitivity to organochlorine exposure at lower thyroid hormone levels, with inflammatory factors potentially mediating the adverse effects of organochlorines on lung function.

PURPOSE: To investigate the incidence and influencing factors of bone loss in patients with spinal cord injury (SCI). METHODS: A retrospective case-control study was conducted. Patients with SCI in our hospital from January 2019 to March 2023 were collected. According to the correlation between bone mineral density (BMD) at different sites, the patients were divided into the lumbar spine group and the hip joint group. According to the BMD value, the patients were divided into the normal bone mass group (t > -1.0 standard deviation) and the osteopenia group (t ≤ -1.0 standard deviation). The influencing factors accumulated as follows: gender, age, height, weight, cause of injury, injury segment, injury degree, time after injury, start time of rehabilitation, motor score, sensory score, spasticity, serum value of alkaline phosphatase, calcium, and phosphorus. The trend chart was drawn and the influencing factors were analyzed. SPSS 26.0 was used for statistical analysis. Correlation analysis was used to test the correlation between the BMD values of the lumbar spine and bilateral hips. Binary logistic regression analysis was used to explore the influencing factors of osteoporosis after SCI. p < 0.05 was considered statistically significant. RESULTS: The incidence of bone loss in patients with SCI was 66.3%. There was a low concordance between bone loss in the lumbar spine and the hip, and the hip was particularly susceptible to bone loss after SCI, with an upward trend in incidence (36% - 82%). In this study, patients with SCI were divided into the lumbar spine group (n = 100) and the hip group (n = 185) according to the BMD values of different sites. Then, the lumbar spine group was divided into the normal bone mass group (n = 53) and the osteopenia group (n = 47); the hip joint group was divided into the normal bone mass group (n = 83) and the osteopenia group (n = 102). Of these, lumbar bone loss after SCI is correlated with gender and weight (p = 0.032 and < 0.001, respectively), and hip bone loss is correlated with gender, height, weight, and time since injury (p < 0.001, p = 0.015, 0.009, and 0.012, respectively). CONCLUSIONS The incidence of bone loss after SCI was high, especially in the hip. The incidence and influencing factors of bone loss in the lumbar spine and hip were different. Patients with SCI who are male, low height, lightweight, and long time after injury were more likely to have bone loss.

Objective To evaluate the effect of Intravascular lithotripsy(IVL)in the treatment of calcified nodules,and to observe the presence of coronary dissection after IVL treatment.Methods A total of 106 patients with coronary atherosclerotic heart disease(coronary heart disease)admitted to the cardiovascular Department of Shougang Hospital,Peking University from March 2023 to July 2024 were retrospectively analyzed.A total of 106 patients with moderate to severe stenosis accompanied by calcification as detected by coronary angiography were treated with IVL after intravascular ultrasound(IVUS)examination.Patients were divided into two groups according to whether there were calcified nodules in the coronary lesions:39 cases in the calcified nodules group and 67 cases in the non-calcified nodules group.The occurrence of coronary dissection during surgery was observed between the two groups,and other perioperative related complications and major adverse cardiovascular events(MACE)within 1 month after percutaneous coronary intervention(PCI)were compared between the two groups.Results The levels of renal insufficiency(25.6％vs.9.0％,P=0.021)and creatinine[(119.71±134.75)μmol/L vs.(71.82±16.53)μmol/L,P=0.033]in the calcified nodule group were higher than those in the non-calcified nodule group,the difference was statistically significant,and there was no difference in other baseline data.The target vessels in the calcified nodule group were mainly left anterior descending branch and right coronary artery,while those in the non-calcified nodule group were mainly left anterior descending branch,with few circumflex branches in both groups,and there was statistical significance in the distribution of target vessels in the left anterior descending branch and right coronary artery between the two groups(P=0.020).In terms of eccentric calcification(P=0.048)and asymmetric calcification(48.7％vs.28.4％,P=0.035)between the two groups,the calcified nodule group was higher than the non-calcified nodule group,the difference was statistically significant(P＜0.05).In terms of whether more than 20 pulses were needed and whether there was slippage during IVL,the calcified nodule group was higher than the non-calcified nodule group,the difference was statistically significant(P=0.022).The success rate of interventional therapy was 100％in both groups.After IVL treatment,the calcified nodule group was higher than the non-calcified nodule group in terms of the occurrence of coronary artery dissection,the difference was statistically significant(P＜0.009).The MACE of the two groups within 1 month after PCI was slightly higher in the calcified nodule group than in the non-calcified nodule group,but the difference was not statistically significant(P=0.235).Conclusions IVL is feasible and effective for the treatment of calcified coronary nodules.However,in the course of treatment,the occurrence of coronary dissection should be vigilant,identified as early as possible,and treated in time.

Objective:To investigate and summarize the imaging and pathological features of non-acute occlusion following flow diverter (FD) implantation in animal models.Methods:Four experimental pigs (experimental group) that experienced non-acute occlusion (occlusion time exceeding 24 hours) within the FD stent implanted in the common carotid artery, and 19 pigs (control group) that did not experience stent occlusion during the same period were involved. Using an interventional approach under digital subtraction angiography (DSA), the 4 occluded FD lumens were mechanically opened. Optical coherence tomography (OCT), intravascular ultrasound (IVUS) and histopathological examinations were performed to evaluate the intraluminal composition and characteristics of the occlusive tissues. These findings were compared with non-occluded FD stents to summarize the imaging and pathological changes within the occluded FD lumen.Results:The occlusion times of the FD stents in the 4 experimental pigs were 16 weeks, 20 weeks, 20 weeks, and 24 weeks postoperatively. All occluded stents were successfully recanalized under DSA, with a technical success rate of 4/4. Among the 19 non-occluded FD stents, OCT and IVUS revealed uniform (16 stents) or non-uniform (3 stents) neointimal coverage of the stent struts, presenting as homogeneous high/slightly high signal intensity or medium echogenicity. Histopathological examination indicated that the neointima was primarily composed of smooth muscle cells and a small amount of fibrous connective tissues. In contrast, the 4 occluded FD stents demonstrated excessive neointimal proliferation and plaque formation, leading to luminal loss, as shown by OCT and IVUS. The occlusion tissues predominantly presented as homogeneous high signal intensity with weak attenuation (fibrous plaques) on OCT, with some regions showing blurred low signal intensity and strong attenuation (lipid plaques). IVUS presented homogeneous echogenicity (fibrous plaques) and hypoechogenic zones (lipid plaques). Histopathological examination showed that the occlusion tissues mainly consisted of smooth muscle cells, fibrous connective tissues, and lipids, accompanied by numerous foam cells and a minor presence of inflammatory cells.Conclusions:Histopathological examinations confirm that non-acute occlusion of FD is mainly caused by excessive hyperplasia of intima along with the formation of fibrous plaques and lipid plaques. OCT and IVUS have typical finding in imaging that can assist in determining the cause of stent occlusion as well as the lesion's nature, thereby providing crucial guidance for subsequent clinical treatment and drug selection.

The lesion of the left main coronary artery(LM)itself is one of the challenges of interventional therapy.If the lesion is combined with calcification,the interventional therapy is difficult to operate and extremely risky.This case report presents a 77-year-old elderly male patient.Coronary angiography(CAG)indicated severe stenosis of the LM-left anterior descending(LAD)accompanied by severe calcified bifurcation lesions.After pre-dilation,percutaneous coronary intraluminal shock wave balloon catheter angioplasty(IVL)was applied for treatment.Before IVL treatment,the LM-LAD lesion was subjected to ischemic preconditioning by using an appropriate balloon to fix the pressure and gradually upgrading the balloon dilation time.Later,a Cross-over procedure was performed to implant a single stent,achieving satisfactory results.Among them,the ischemic preconditioning methods for LM lesions can provide reference significance for clinicians.
