In recent years， data mining algorithms have been widely employed in scientific research within the field of traditional Chinese medicine （TCM）. The data mining algorithms are used to effectively handle and analyze the complex data in TCM formulas， providing a rational explanation for the mechanism of action. This method has proven particularly useful in uncovering patterns of compatibility and frequent combinations of herbs in TCM， thereby enhancing the reliability and accuracy of clinical diagnosis， target screening， and the study of new drugs. This paper reviews and analyzes 147 papers on TCM formula research that utilize data mining algorithms. The results indicate that data mining algorithms play a unique advantage in six sub- areas， including the study on the mechanism of action in TCM formula， the dose-efficacy of TCM formulas， the identification of core drugs pairs/groups， mining the relationships among “formulas-drug-symptom”， the discovery of new formulas， and mining the compatibility law. Notably， association rules and clustering algorithms are the most representative.

Objective:This study aimed to investigate the predictive value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) trajectory on future major adverse cardiovascular events (MACE) in patients with stable coronary artery disease (SCAD) after percutaneous coronary intervention (PCI).Methods:A retrospective cohort study was conducted on SCAD patients admitted to the Department of Cardiology at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, from January 2013 to December 2021. A total of 828 subjects were enrolled, comprising 592 males and 236 females, with an average age of (66.44±11.71) years. SCAD patients post-percutaneous coronary intervention (PCI) were stratified into three NT-proBNP trajectory groups: T1 Low-Low (219 cases), T2 Medium-Low (363 cases), and T3 High-High (246 cases). The median follow-up time was 2.1 years, and the maximum follow-up time was 9 years. The primary clinical endpoint event was MACE. The NT-proBNP concentration in patients′ serum was measured using enzyme-linked fluorescent assay, and different trajectory groups were determined using latent class trajectory modeling. The association between NT-proBNP trajectory and occurrence of MACE in SCAD patients was evaluated using Kaplan-Meier survival curves and multivariable Cox proportional hazards regression models.Results:A total of 67 (8.1%) major adverse cardiovascular events occurred, including 43 cases (5.2%) of all-cause mortality, 13 cases (1.6%) of heart failure death, 9 cases (1.1%) of non-fatal myocardial infarction, and 15 cases (1.8%) of non-fatal stroke. Kaplan-Meier survival curve analysis showed significant differences in survival rates among T1, T2, and T3 groups of SCAD patients for MACE, all-cause mortality, and heart failure death (all P<0.001). In the multivariable Cox regression analysis, the risk of MACE occurrence for patients in the T2 group and T3 group was 1.708 times (95% CI 0.72-4.05) and 3.842 times (95% CI 1.625-9.081) compared to the T1 group, respectively. Moreover, a statistically significant linear trend was observed for the risk of MACE occurrence across trajectory groups ( P<0.001). Conclusions:NT-proBNP trajectory groups after PCI in SCAD patients are strongly associated with the risk of MACE occurrence and can serve as an independent predictor for MACE. Dynamic monitoring of NT-proBNP during follow-up to obtain longitudinal trajectories helps identify high-risk SCAD patients and implement timely effective intervention measures.

【Objective】 To investigate the effect or endoscopic discectomy via interlaminar approach in the treatment of lumbar disc herniation under local or general anesthesia. 【Methods】 We selected 78 patients with lumbar disc herniation （L5-S1） who underwent endoscopic discectomy via interlaminar approach from January 2018 to February 2020. According to the anesthesia method， they were divided into local anesthesia group （40 patients） and general anesthesia group （38 patients）. Baseline data， complications， operation time， length of hospital stay， hospitalization expenses， preoperative and postoperative VAS scores were compared between the two groups to evaluate the difference in clinical outcomes. 【Results】 There was no significant difference between the two groups in gender （23/17 vs. 20/18）， age （38.45±13.59 vs 37.39±13.35） years， preoperative VAS score （7.05±1.32 vs. 6.95±1.47）， or other baseline data （P>0.05）. The operation was completed successfully in both groups， and the operation time （83.57±13.24 vs. 86.28±15.43） minutes did not statistically differ （P>0.05）. No complications such as cerebrospinal fluid leakage， nerve injury， or wound infection occurred. In the local anesthesia group， the VAS pain score at 1d， 1 month and 6 months after surgery was 3.05±1.34， 1.90±0.98 and 1.80±1.09， respectively， which were significantly lower than those before surgery （P<0.001）. The VAS pain scores of the general anesthesia group at the above three time points were 3.24±2.01， 2.03±1.20 and 1.59±1.31， respectively， which were also significantly lower than those before surgery （P<0.001）， but the difference was not statistically significant compared with that of the local anesthesia group at the same time point （P>0.05）. However， compared with the general anesthesia group， the length of hospital stay （2.93±0.92） d and the cost of hospitalization （29 397.97±1 398.09） yuan in the local anesthesia group were decreased by 25.8% and 11.7%， respectively， with statistical significance （P<0.05）. 【Conclusion】 Endoscopic discectomy through interlaminar approach under local or general anesthesia can achieve good clinical outcomes in the treatment of lumbar disc herniation （L5-S1）. Compared with general anesthesia， local anesthesia brings a lower overall cost and a shorter hospital stay.

Objective:To investigate the risk factors of refracture of the injured vertebrae after percutaneous vertebral augmentation for acute symptomatic thoracolumbar osteoporotic compression fractures (ASTOCFs).Methods:A case-control study was conducted to analyze the clinical data of 2 237 ASTOCFs patients admitted to three hospitals from January 2010 to January 2019. There were 569 males and 1 668 females, with age range of 50-85 years [(66.7±4.8)years]. The patients underwent percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). According to the radiographic outcomes, the patients were divided into refracture group ( n=315) and non-refracture group ( n=1 922). Data were recorded for the two groups, including basic demographics (gender, age, height and weight), personal habits (smoking and alcohol consumption), basic diseases (diabetes, hypertension, coronary heart disease and chronic obstructive pulmonary disease), preoperative bone mineral density, fracture segment, number of injured vertebrae, surgical method (PVP or PKP), surgical approach, bone cement viscosity, distance from cement to the upper and lower endplate, cement volume in injured vertebrae, cement leakage, postoperative exercise, and postoperative anti-osteoporosis treatment. The above data were analyzed to identify their correlation with postoperative refracture of the injured vertebrae by univariate analysis. The independent risk factors for postoperative refracture of the injured vertebrae were determined by multivariate Logistic regression analysis. Results:Univariate analysis showed that refracture of injured vertebrae was correlated with gender, age, diabetes, fracture segment, surgical method, distance from cement to the upper and lower endplate, postoperative exercise, and postoperative anti-osteoporosis treatment ( P<0.05 or 0.01), but there was no correlation with height, weight, smoking, alcohol consumption, hypertension, coronary heart disease, chronic obstructive pulmonary disease, preoperative bone mineral density, number of fractured vertebrae, surgical approach, bone cement viscosity, cement volume in injured vertebrae or cement leakage (all P>0.05). Multivariate Logistic regression analysis showed that female ( OR=1.92, 95% CI 1.34-2.64, P<0.01), age ≥80 years ( OR=1.21, 95%CI 1.17-1.25, P<0.01), diabetes ( OR=1.92, 95% CI 0.44-2.55, P<0.01), thoracolumbar fracture ( OR=1.46, 95% CI 1.82-7.51, P<0.05), PKP ( OR=4.56, 95% CI 0.86-1.44, P<0.05), no postoperative exercise ( OR=2.14,95% CI 0.27-0.38, P<0.01), and no postoperative anti-osteoporosis treatment ( OR=2.36,95% CI 0.13-0.47, P<0.05) were positively correlated with refracture of injured vertebrae. Conclusion:Female, age ≥80 years, diabetes, thoracolumbar fracture, PKP, no postoperative exercise, and no postoperative anti-osteoporosis treatment are independent risk factors for refracture of injured vertebrae after percutaneous vertebral augmentation for ASTOCFs.

Objective:To evaluate the efficacy and safety of bendamustine monotherapy in Chinese patients with relapsed/refractory (R/R) B cell non-Hodgkin lymphoma (B-NHL) .Methods:This prospective, multicenter, open label, single-arm, phase Ⅱ study investigated bendamustine’s efficacy and safety in Chinese patients with R/R B-NHL. A total of 78 patients with B-NHL in 11 hospitals in China from March 2012 to December 2016 were included, and their clinical characteristics, efficacy, and survival were analyzed.Results:The median age of all patients was 58 (range, 24-76) years old, and 69 (88.4% ) patients had stage Ⅲ/Ⅳ disease. 61 (78.2% ) patients were refractory to previous treatments. Patients received a median of 4 (range, 1-10) cycles of bendamustine treatment. The overall response rate was 61.5 (95% CI 49.8-72.3) % , the median response duration was 8.3 (95% CI 5.5-14.0) months, and the complete remission (CR) rate was 5.1 (95% CI 1.4-12.6) % . In the full analysis set, median progression-free survival (PFS) and median OS were 8.7 (95% CI 6.7-13.2) months and 25.5 months (95% CI 14.2 months to not reached) , respectively, after a median follow-up of 33.6 (95% CI 17.4-38.8) months. Lymphopenia (74.4% ) , neutropenia (52.6% ) , and leukopenia (39.7% ) , thrombocytopenia (29.5% ) and anemia (15.4% ) were the most common grade 3-4 hematologic adverse events (AE) . The most frequent non-hematologic AEs included nausea (43.6% ) , vomiting (33.3% ) , and anorexia (29.5% ) . Univariate and multivariate analysis showed that <4 cycles of bendamustine treatment was a poor prognostic factor for PFS ( P=0.003) , and failure to accept fludarabine containing regimen was a poor prognostic factor for OS ( P=0.009) . Conclusion:Bendamustine monotherapy has good efficacy and safety in the treatment of patient with R/R B-NHL.

Objective:To investigate the clinical efficacy of P-GEMOX (pegaspargase, gemcitabine and oxaliplatin) as a first-line regimen for the treatment of primary extranasal nasal-type NK/T cell lymphoma (NKTCL).Methods:The clinical manifestations, treatment response and prognosis of 7 patients with primary extranasal nasal-type NKTCL who underwent P-GEMOX chemotherapy as a first-line therapy in Shenzhen People's Hospital from September 2015 to October 2018 were retrospectively analyzed.Results:The median age of 7 patients with primary extranasal nasal-type NKTCL was 41 years old (27-74 years old), which was more commonly found in males (6 cases); the primary and invading extranasal sites included ileocecal, lymph nodes, skin, testis, adrenal gland, central nervous system, etc. The P-GEMOX regimen was used as a first-line therapy, although some patients had a short-term effect, all patients eventually progressed rapidly and died. The overall survival time was 2 weeks to 21 months.Conclusion:The short-term efficacy of P-GEMOX as a first-line therapy for the treatment of primary extranasal nasal-type NKTCL is acceptable, but the long-term efficacy is poor.

Objective:To describe a systematic approach on identification of poisonous mushroom by investigating two cases of Omphalotus guepiniformis poisoning in Jianyang district, Nanping, Fujian province. Methods:Two incidents of food poisoning on 10 migrant workers were investigated. The remaining suspected mushroom samples were collected and the same fresh mushroom specimens were also collected in the following field investigations from the same dead tree and fallen trunk. These mushroom specimens were identified based on morphological and phylogenetic analyses.Results:On November 24 and 26, 2018, 8 and 2 migrant workers from Jianyang District, Nanping ate wild mushrooms and developed acute nausea, vomiting, abdominal pain and other symptoms within 10 to 90 min after consumption. They were diagnosed as mushroom poisoning, with gastroenteritis as the main manifestation. Further analysis showed that the more poisonous mushroom were consumed, the shorter latency and longer duration of nausea and vomiting were resulted. After admission, gastric lavage, catharsis, acid preparation, gastric protection, fluid replenishment and other symptomatic support treatments were given in time, all patients were discharged in 1-3 d. Based on morphological and phylogenetic analyses, the samples were identified as O. guepiniformis. Conclusions:The two incidents were caused by accidental consumption of O. guepiniformis. Awareness education about poisonous mushroom should be provided to migrant workers to prevent more such poisoning incidents in the future.
