OBJECTIVE To further standardize the technical operations and management processes throughout therapeutic drug monitoring （TDM）， clarify the clinical value of TDM implementation， improve the scientific validity and reliability of monitoring results， and provide a solid reference basis for the formulation and optimization of clinical individualized precision dosing regimens. METHODS The Guidelines for the Management of Therapeutic Drug Monitoring were formulated in accordance with the latest definition of guidelines by the Institute of Medicine of the National Academies and the standard guideline development methodology of the World Health Organization， and in compliance with the requirements of the appraisal of guidelines for research and evaluation. A modified Delphi method was adopted to establish the research question system； evidence-based medicine research methods were applied to systematically search multiple databases to screen the latest and most comprehensive evidence. Evidence was graded and evaluated based on the evidence grading system of the Chinese Evidence-Based Medicine Center， and the grading criteria for recommendation strength from the Oxford Centre for Evidence-Based Medicine were used to determine the recommendation strength. The recommendation opinions were formed through multidisciplinary expert consensus. RESULTS The Guidelines for the Management of Therapeutic Drug Monitoring cover four core modules， including TDM application indications， technical procedures， result interpretation and clinical application， and quality control， involving 18 primary research questions， 34 secondary research questions， and yield 82 recommendations. CONCLUSIONS The guidelines systematically standardize the key technical links and management requirements of the whole TDM process， provide scientific and operable standardized tools， help improve the standardization level of TDM work， promote the translation of monitoring results into clinical decision-making， and provide strong support for precision personalized medicine and ensuring the safety and rationality of medication use.

Objective To explore the principle of antibacterial drug therapy and the strategy of program optimization in elderly patients with Helicobacter pylori（Hp）. Methods The common therapeutic regimen of Hp was summarized, and the better therapeutic regimen of elderly Hp patients was screened ultimately. Results Amoxicillin and cefuroxime were relatively safe compared with other recommended antibacterial drugs. Using other commonly antibiotics for Hp should pay attention to the disease of patients and current drug. Conclusion Elderly patients usually suffered from a variety of diseases and required multiple drugs. The application of therapeutic regimen for elderly patients with Hp should be supposed to fully weigh the risks and benefits.

Objective To explore the effects of nicotinamide mononucleotide （NMN） on hypertensive rats. Methods Two rat hypertension models including spontaneously hypertensive rats（SHR）and two-kidney two-clip （2K2C） rats were used to be given single, long-term or lifelong administration of NMN respectively. NMN’s effects were assessed comprehensively by monitoring survival time, blood pressure levels, and the extent of organ damage in hypertensive model rats. Results It was revealed that NMN did not exhibit protective effects in terms of lowering blood pressure levels, reducing organ damage or increasing survival time in hypertensive rats. Conclusion This study suggested that NMN did not demonstrate anti-hypertensive effects in rat hypertension models and could provide valuable insights for future clinical observation on NMN.

ObjectiveRepetitive transcranial magnetic stimulation (rTMS) has demonstrated efficacy in enhancing neurocognitive performance in Alzheimer’s disease (AD), but the neurobiological mechanisms linking synaptic pathology, neural oscillatory dynamics, and brain network reorganization remain unclear. This investigation seeks to systematically evaluate the therapeutic potential of rTMS as a non-invasive neuromodulatory intervention through a multimodal framework integrating clinical assessments, molecular profiling, and neurophysiological monitoring. MethodsIn this prospective double-blind trial, 12 AD patients underwent a 14-day protocol of 20 Hz rTMS, with comprehensive multimodal assessments performed pre- and post-intervention. Cognitive functioning was quantified using the mini-mental state examination (MMSE) and Montreal cognitive assessment (MOCA), while daily living capacities and neuropsychiatric profiles were respectively evaluated through the activities of daily living (ADL) scale and combined neuropsychiatric inventory (NPI)-Hamilton depression rating scale (HAMD). Peripheral blood biomarkers, specifically Aβ1-40 and phosphorylated tau (p-tau181), were analyzed to investigate the effects of rTMS on molecular metabolism. Spectral power analysis was employed to investigate rTMS-induced modulations of neural rhythms in AD patients, while brain network analyses incorporating topological properties were conducted to examine stimulus-driven network reorganization. Furthermore, systematic assessment of correlations between cognitive scale scores, blood biomarkers, and network characteristics was performed to elucidate cross-modal therapeutic associations. ResultsClinically, MMSE and MOCA scores improved significantly (P<0.05). Biomarker showed that Aβ1-40 level increased (P<0.05), contrasting with p-tau181 reduction. Moreover, the levels of Aβ1-40 were positively correlated with MMSE and MOCA scores. Post-intervention analyses revealed significant modulations in oscillatory power, characterized by pronounced reductions in delta (P<0.05) and theta bands (P<0.05), while concurrent enhancements were observed in alpha, beta, and gamma band activities (all P<0.05). Network analysis revealed frequency-specific reorganization: clustering coefficients were significantly decreased in delta, theta, and alpha bands (P<0.05), while global efficiency improvement was exclusively detected in the delta band (P<0.05). The alpha band demonstrated concurrent increases in average nodal degree (P<0.05) and characteristic path length reduction (P<0.05). Further research findings indicate that the changes in the clinical scale HAMD scores before and after rTMS stimulation are negatively correlated with the changes in the blood biomarkers Aβ1-40 and p-tau181. Additionally, the changes in the clinical scales MMSE and MoCA scores were negatively correlated with the changes in the node degree of the alpha frequency band and negatively correlated with the clustering coefficient of the delta frequency band. However, the changes in MMSE scores are positively correlated with the changes in global efficiency of both the delta and alpha frequency bands. Conclusion20 Hz rTMS targeting dorsolateral prefrontal cortex (DLPFC) significantly improves cognitive function and enhances the metabolic clearance of β-amyloid and tau proteins in AD patients. This neurotherapeutic effect is mechanistically associated with rTMS-mediated frequency-selective neuromodulation, which enhances the connectivity of oscillatory networks through improved neuronal synchronization and optimized topological organization of functional brain networks. These findings not only support the efficacy of rTMS as an adjunctive therapy for AD but also underscore the importance of employing multiple assessment methods—including clinical scales, blood biomarkers, and EEG——in understanding and monitoring the progression of AD. This research provides a significant theoretical foundation and empirical evidence for further exploration of rTMS applications in AD treatment.

Objective:To systematically synthesize the experiences and needs of thyroid cancer patients and their stakeholders in participating in treatment decision-making, so as to provide evidence-based theoretical support for the development of localized decision aids and the implementation of shared decision-making in China.Methods:A systematic search was conducted in PubMed, Web of Science, Cochrane Library, Embase, CINAHL, China National Knowledge Infrastructure, VIP, Wanfang Data, and China Biomedical Literature Database for qualitative studies on the experiences and needs of thyroid cancer patients and their stakeholders in treatment decision-making. The search covered the period from the establishment of the databases to May 20, 2025. The 2020 version of the Joanna Briggs Institute (JBI) critical appraisal tool for qualitative research was used to assess study quality. Aggregative synthesis was applied to integrate the findings.Results:A total of 19 studies were included, from which 94 individual findings were extracted. These findings were categorized into 15 new categories and further synthesized into four overarching themes: role dynamics in treatment decision-making; challenging trade-offs between risks and benefits of treatment choices; multifactorial influences on treatment decisions; and multidimensional support needs.Conclusions:Treatment decision-making among thyroid cancer patients involves complex role identification, conflicting emotional experiences, and risk-benefit deliberations influenced by multiple factors. It is essential to build a "clinician-family-society" decision-support ecosystem encompassing informational, psychological, and social support. Future efforts should focus on developing culturally appropriate decision aids that integrate emotional support and innovative technologies to promote shared decision-making, enhance decision quality, and improve patient satisfaction.

Objective To investigate the expression levels of LINC02009 and LOC107984895 in peripheral lymphocytes of patients with atrial fibrillation and their clinical significance.Methods A total of 75 hospitalized patients with atrial fibrillation(50 with persistent atrial fibrillation and 25 with paroxysmal atrial fibrillation)from Kunming First People's Hospital between January 2023 and December 2023 were selected as study subjects,along with 50 normal control patients.Real-time quantitative PCR was used to detect the expression levels of LINC02009 and LOC107984895 in peripheral blood leukocytes of patients with atrial fibrillation.Logistic regression analysis was employed to assess the relationship between expression levels and risk factors for atrial fibrillation,and ROC curves were used to predict the diagnostic cut-off values for LINC02009 and LOC107984895 in diagnosing atrial fibrillation.Results There were statistically significant differences in baseline diseases such as hypertension and coronary heart disease,biochemical indicators such as Cr and BNP,and myocardial remodeling indicators such as LAd and LVEF between the AF(paroxysmal atrial fibrillation and persistent atrial fibrillation)group and the Normal group(P＜0.05).The expression levels of LINC02009 and LOC 107984895 in the plasma of the atrial fibrillation group were significantly higher than those in the control group(P＜0.05)and were negatively correlated with LVEF(P＜0.05).The areas under the curve(AUC)of LINC02009 and LOC 107984895 in predicting atrial fibrillation were 0.967(95％CI:0.938～0.995)and 0.900(95％CI:0.838～0.963),respectively.The optimal cut-off values were 1.985 and 0.915,with sensitivities of 88％and 76％,respectively,and specificities of 94％and 90％,respectively.Conclusion LINC02009 and LOC 107984895 are independent risk factors for atrial fibrillation and have certain predictive value for the occurrence of atrial fibrillation.

Objective To evaluate the prevention and control effectiveness of four major chronic diseases in Youyang County, and find the weak link of prevention and control, and to provide theoretical support for improving prevention and control strategies. Methods Based on the death data of permanent residents from 2012 to 2020 extracted from the cause-of-death registration and reporting system of Youyang County, a statistical analysis was conducted using SPSS19.0. The annual percentage change (APC) was tested by t-test. Results From 2012 to 2020, the mortality rate of and the standardized mortality rate of the four major chronic diseases and the premature mortality rate of diabetes in males showed an increasing trend (APC was 3.05%, 1.82% and 27.12%, respectively, P < 0.05). The mortality rate of the four chronic diseases in females increased (APC was 2.53%, P < 0.05), while the proportion of premature death of the four chronic diseases and the probability of premature death of cardiovascular and cerebrovascular diseases in females decreased (APC was -2.37%, -5.73%, P < 0.05). The standardized mortality rate and premature death rate of the four major chronic diseases were higher in males than those in females. The mortality rate of the four major chronic diseases and the premature death rate of diabetes in the whole population were on the rise (APC was 2.84% and 12.86%, P < 0.05). It was expected that the early death probability of the four major chronic diseases in Youyang County would be 12.65% in 2030, higher than the target value of 12.59% of ^“Healthy China 2030^”. Conclusion The future focus of Youyang County is to prevent and control malignant tumors and diabetes, especially to strengthen the prevention and control of male diabetes.

OBJECTIVE: To explore the effectiveness of arthroscopic All-inside single needle vertical suture technique in treatment of complete radial tear of the meniscus. METHODS: Between January 2019 and January 2022, 18 patients (18 knees) with complete radial tear of the meniscus were treated by using arthroscopic All-inside single needle vertical suture technique. Among them, there were 12 males and 6 females with an average age of 37.1 years (range, 16-50 years). The causes of radial meniscus tears included the sports injuries in 11 cases, sprains/falls in 4 cases, and traffic accident injuries in 3 cases. The interval between injury and operation was 3-25 days (mean, 11.7 days). All patients had knee joint pain. Knee joint tenderness and McMurray sign were both positive. MRI showed the 15 cases of lateral meniscus tear and 3 cases of medial meniscus tear; 15 cases of anterior cruciate ligament injury, 1 case of posterior cruciate ligament injury, and 15 cases of tibial plateau bone contusion. Six patients underwent isolated meniscus repair and 12 patients with cruciate ligament rupture underwent meniscus repair and simultaneous cruciate ligament reconstruction. The operation time and incidence of postoperative complications were recorded. At last follow-up, the meniscus healing was evaluated according to Barrett's criteria and knee joint MRI, respectively. Lysholm score and International Knee Documentation Committee (IKDC) score were used to evaluate the functional recovery of the knee joint. RESULTS: The operation time was 19-28 minutes (mean, 23.3 minutes) in 6 patients with isolated meniscus repair and 38-52 minutes (mean, 45.8 minutes) in 12 patients with meniscus repair and simultaneous cruciate ligament reconstruction. All incisions healed by first intention. After operation, 1 patient developed the deep vein thrombosis of lower limb, the other patients had no complication. All patients were followed up 12-18 months (mean, 15.2 months). At last follow-up, 16 cases of meniscus reached clinical healing according to Barrett's criteria, with a healing rate of 88.9%. MRI re-examination of the knee joint showed that 5 cases had complete healing of the meniscus, 11 cases had partial healing, and 2 cases did not heal. The total healing rate (complete healing and partial healing) was 88.9%. After operation, the Lysholm score and IKDC score of 18 patients increased compared to preoperative scores, and further improved with time. The differences between different time points were significant ( P<0.05). Six patients with isolated meniscus repair had the same changes in the above scores, and the differences between the different time points were significant ( P<0.05). CONCLUSION The arthroscopic All-inside single needle vertical suture technique can achieve good short-term effectiveness in the treatment of complete radial tears of the meniscus.
