OBJECTIVE To construct specialized file management and risk warning system for narcotic drugs， and promote the refined management of narcotic drugs in medical institutions. METHODS Through the rational medication management system， patient-indexed narcotic drug medication record information was integrated， pain assessment and rapid dose titration modules were constructed， and a prescription pre-review risk warning model was established. Statistical analysis was conducted on the number of drugs returned by patients， interventions for adverse events related to narcotic drug abuse， patient and physician satisfaction， and patient medication adherence before the system was constructed （January-July 2023） and after its stable operation （January-July 2024）. RESULTS After the construction of the system， the number of narcotic drugs returned by patients decreased， except for Morphine tablets. The number of interventions for adverse events related to narcotic drug abuse increased from 0 to 5 cases. The patients’ satisfaction with pain control increased from 46.25% to 67.50%， the proportion of patients with poor adherence decreased from 23.75% to 7.50%， and the overall satisfaction of physicians was 72.41%. CONCLUSIONS The construction of a specialized file management and risk warning system for narcotic drugs enables refined management of narcotic drugs， provides alerts for abnormal prescriptions， reduces patient stockpiling of narcotic drugs， allows timely detection and intervention of adverse events related to narcotic drug abuse， improves physician treatment efficiency and precision， and enhances patient pain control satisfaction and medication adherence.

OBJECTIVE To investigate the effect of plasma trough concentration of venetoclax and its influencing factors in patients with acute myeloid leukemia （AML）. METHODS After 5 days of venetoclax administration， venous blood samples were collected from AML patients before the next dose. Plasma trough concentrations of venetoclax were determined using high-performance liquid chromatography-tandem mass spectrometry. Spearman correlation was used to assess the correlations between venetoclax plasma trough concentration and various parameters （including patients’ general information， venetoclax-related indicators， liver function indicators， kidney function indicators， and blood routine indicators）. Multiple linear regression analysis was performed to identify independent factors influencing plasma trough concentration of venetoclax. Using efficacy as dependent variable [complete remission （CR）+partial remission （PR） vs. no remission （NR）]， univariate and multivariate binary Logistic regression analyses were conducted to identify factors affecting efficacy. The receiver operating characteristic （ROC） curve was used to evaluate the predictive value of venetoclax plasma trough concentration for clinical efficacy （assessed as CR）. RESULTS A total of 172 venetoclax plasma trough concentration measurements from 101 patients were included in this study. The median plasma trough concentration of venetoclax was 2.38 （1.18， 3.85） μg/mL； the median sampling time for plasma trough concentration of venetoclax was 10 （7， 15） d； the duration of venetoclax use was （34±12） d. Multiple linear regression analysis showed that alkaline phosphatase （ B ＝14.65， 95%CI： 5.35-23.95， P ＝0.002）， total bilirubin （ B ＝－101.71， 95%CI： －197.16 to －6.25， P ＝0.037）， and white blood cell count （ B ＝－106.84， 95%CI： －187.61 to －26.07， P ＝0.010） were independent factors influencing plasma trough concentration of venetoclax. Due to patient attrition during treatment， 114 venetoclax plasma trough concentration measurements from 69 patients were included for efficacy evaluation. The results showed that 46 patients （66.7%） achieved CR， 11 patients （15.9%） achieved PR， and 12 patients （17.4%） were NR. Multivariate binary Logistic regression analysis showed that age， hemoglobin， venetoclax plasma trough concentration， hematocrit， and mean corpuscular hemoglobin were independent factors affecting patient efficacy （ P ＜0.05）. ROC curve analysis showed that the cut-off value of plasma trough concentration of venetoclax for predicting patient efficacy （assessed as CR） was 1.68 μg/mL （AUC＝0.66， 95%CI： 0.54-0.78， P ＝0.014）. CONCLUSIONS There is considerable inter-individual variability in plasma trough concentration of venetoclax among AML patients. Plasma trough concentration of venetoclax is significantly correlated with alkaline phosphatase， total bilirubin， and white blood cell count. Plasma trough concentration of venetoclax is an independent factor affecting patient’s efficacy， and when the cut-off value for predicting CR is above 1.68 μg/mL， better effects may be achieved.

ObjectiveTo explore the incidence of major low anterior resection syndrome （LARS） within six months after sphincter-preserving surgery for rectal cancer and to analyze its associated factors. MethodsClinical records， postoperative rehabilitation data and LARS scores were collected from 889 patients at 3 months postoperatively and from 844 patients at 6 months postoperatively. Patients were divided into a major LARS group and a non-major LARS group. Multivariable Logistic regression was used to analyze factors associated with major LARS at 3 and 6 months postoperatively， and the predictive value of the models was assessed using the Hosmer-Lemeshow goodness-of-fit test and the receiver operating characteristic （ROC）. ResultsAmong patients undergoing sphincter-preserving surgery for rectal cancer， 247 patients （27.8%） had major LARS at 3 months postoperatively and 181 patients （21.4%） at 6 months postoperatively. Multivariable Logistic regression showed that Kegel exercises， preoperative radiotherapy， anastomotic leakage， a tumor distance from the anal verge of ≤5 cm， and an anastomotic distance from the anal verge of ≤5 cm were independent factors for major LARS at 3 months postoperatively （P<0.05）. At 6 months postoperatively， occasional Kegel exercises during 0~3 months， Kegel exercises during 4~6 months， hydrotherapy during 4~6 months， preoperative chemotherapy， a tumor distance from the anal verge of ≤5 cm， and an anastomotic distance from the anal verge of ≤5 cm were independent factors （P<0.05）. The models at 3 and 6 months postoperatively showed goodness-of-fit test P values of 0.986 and 0.517 and area under the curve （AUCs） of 0.843 and 0.870， indicating good predictive value. ConclusionThe incidence of major LARS within six months after sphincter-preserving surgery for rectal cancer is relatively high， and greater attention should be paid to patients who receive preoperative chemoradiotherapy， develop anastomotic leakage， or have tumor and anastomotic distances from the anal verge of ≤5 cm. Patients should also be advised that early postoperative Kegel exercises and hydrotherapy may reduce the incidence of major LARS.

To address the growing challenge of an increasing number of elderly lung cancer patients amidst China's aging population and to fill the gap in quality control standards for surgical treatment in this special population, this study aimed to develop a standardized surgical evaluation system for elderly lung cancer patients tailored to China's national conditions. The system was established through a literature review, integrated the pathophysiological characteristics of elderly patients, and was constructed following review, feedback, and revision by experts from multiple thoracic surgery centers. Employing a 100-point scoring system, it comprises three primary domains: physical infrastructure and geriatric adaptability foundational conditions (10 points); management level and perioperative care models (20 points); and technical proficiency and clinical outcomes (70 points). The system places a strong emphasis on geriatric adaptability, proposing specific, quantifiable indicators for age-friendly facility modifications, control of elderly-specific complications, multidisciplinary collaboration, and standardized perioperative management. It provides a convenient and measurable assessment tool for quality control in the surgical treatment of elderly lung cancer in China, which is expected to promote the standardization and homogenization of diagnosis and treatment.

This study reports a case of a 56-year-old female patient with BRAF-mutated non-small cell lung cancer (NSCLC) who successfully underwent radical surgery after neoadjuvant targeted therapy with the BRAF inhibitor dabrafenib combined with the MEK inhibitor trametinib. The chest drainage tube was removed 2 days postoperatively, and the patient was discharged smoothly. Postoperative pathology indicated invasive adenocarcinoma, moderately to highly differentiated, with 80% being lepidic type, and the maximum tumor diameter was 4 cm. No vascular tumor thrombus, vascular invasion, nerve invasion, spread through air spaces, pleural invasion, or lymph node metastasis were observed. The postoperative staging was ypT2aN0M0. The patient continued with adjuvant treatment with dabrafenib combined with trametinib postoperatively, and no signs of recurrence were found in the follow-up examination six months after surgery.

Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

Objective To investigate the classification capability of a deep learning classification model based on biparametric mag-netic resonance imaging(bpMRI)for clinically significant prostate cancer(csPCa)and clinically insignificant prostate cancer(cisPCa).Methods A retrospective analysis was conducted on the data of 565 prostate bpMRI patients.A deep learning classification model was established for csPCa.The patients were randomly divided into training set(452 cases)and internal test set(113 cases)at a ratio of 8︰2.Internal validation was performed,followed by external validation(external validation set)using data from 120 patients across four different hospitals.The area under the curve(AUC)of the receiver operating characteristic(ROC)curve,F1 score,precision,sensi-tivity,specificity,accuracy,and calibration curves were used to evaluate the model.Decision curve analysis(DCA)was also applied to assess the clinical benefit of the model.Results The deep learn-ing classification model for csPCa classification demonstrated the following performance across the training set,internaltest set,and external validation set:sensitivity of 0.986,0.887,and 0.750;specificity of 0.967,0.850,and 0.976;precision of 0.963,0.839,and 0.818;accuracy of 0.974,0.862,and 0.792;F1 score of 0.974,0.862,and 0.783;and AUC of 0.998,0.896,and 0.883,respec-tively.The calibration curves for all three datasets showed high consistency between predicted and actual probabilities.DCA indicated that the highest net benefit threshold probabilities for the training set,internal test set,and external validation set were 0.2-0.7,0.2-0.6,and 0.2-0.5,respectively.Conclusion The deep learning classification model demonstrated excellent performance in classifying csPCa and exhibited good generalizability,which is worhty of clinical application.

Objective To explore the influencing factors of postoperative pancreatitis in elderly patients with common bile duct stones undergoing endoscopic retrograde cholangiopancreatography(ERCP).Methods 304 elderly patients with common bile duct stones treated with ERCP in our hospital from February 2021 to June 2023 were selected as the study subjects.They were divided into a group with concurrent pancreatitis(n=22)and a group without concurrent pancreatitis(n=282)based on whether postoperative pancreatitis occurred.And the levels of serum lipase,whole blood PLR,and serum CRP were measured before surgery and 3,6,and 24 hours after surgery,respectively.At the same time,the differences in other relevant clinical data between the two groups of patients were compared.Binary Logistic regression was used to analyze the risk factors of pancreatitis after ERCP.Results The serum lipase levels in the concurrent pancreatitis group at 3,6,and 24 hours after the operation were(1060.48±131.23)U/L,(1137.45±126.34)U/L,and(1152.87±135.05)U/L,respectively.The levels of PLR in whole blood were 192.24±29.26,216.45±30.24,and 243.62±38.22 respectively,all of which were higher than those in the group without concurrent pancreatitis during the same period.There was a statistically significant difference between the two groups(P＜0.05).The serum CRP level in the group with pancreatitis was significantly higher than that in the group without pancreatitis at 6 and 24 h after operation(P＜0.05).Body mass index,Oddi sphincter dysfunction,difficulty in intubation,pancreatic development,ERCP operation time＞60 min,multiple entry of the catheter into the pancreatic duct were associated with postoperative pancreatitis after ERCP in elderly patients(P＜0.05).Multivariate Logistic regression analysis showed that after adjusting for confounding factors such as gender,age,BMI,course of disease,and number of stones,Serum lipase at 3 h after surgery,whole blood PLR at 3 h after surgery,serum CRP level at 6 h after surgery,difficulty in intubation and pancreatic development were independent risk factors for pancreatitis after ERCP in elderly patients(P＜0.05).Conclusion Serum lipase,whole blood PLR levels 3 hours after surgery,and serum CRP levels 6 hours after surgery are independent risk factors for pancreatitis after ERCP in the elderly with common bile duct stones.

Objective:To explore the medication law of TCM external therapy for the treatment of diabetic foot using data mining methods.Methods:Literature on TCM external treatment for diabetic foot was retrieved from CNKI, Wanfang Data, and Chongqing VIP from the establishment of the databases to June 30, 2024. Excel 2019 software was used to conduct frequency statistics on drug frequency, properties, tastes and meridian tropism, drug efficacy, and commonly used drug pairs. Ancient and Modern Medical Cases Cloud Platform V3.5 was used for association rules, and SPSS Statistics 27.0 was used for complex network analyses.Results:A total of 425 articles were included, involving 328 prescriptions and 232 drugs. The drugs with higher frequency were Carthami Flos, Angelicae Sinensis Radix, Cinnamomi Ramulus, Olibanum, etc. The main tastes were pungent, bitter, and sweet; the main properties were cold and warm; the main meridians were heart, spleen, and liver meridians. The main efficacy was promoting blood circulation and removing blood stasis, clearing heat, and tonifying deficiency; association rule analysis obtained 20 commonly used drug pairs; clustering analysis resulted in four core drug combinations; complex network analysis led to one core prescription.Conclusions:TCM external therapy for diabetic foot follows the guiding principles of "promoting blood circulation and unblocking collaterals, tonifying deficiency and clearing heat" with coordinated regulation of the "heart-liver-spleen meridians". The core prescription and stage-specific formulation strategies reflect a trinity diagnostic and therapeutic approach of "disease differentiation-syndrome differentiation-stage differentiation", providing valuable reference and insights for clinical prescription practices.
