Traditional Chinese medicine(TCM) decoction pieces are a core carrier for the inheritance and innovation of TCM, and their quality and safety are critical to public health and the sustainable development of the industry. Conventional quality control models, while having established a well-developed system through long-term practice, still face challenges such as relatively long inspection cycles, insufficient objectivity in characterizing complex traits, and urgent needs for improving the efficiency of integrating multidimensional quality information when confronted with the dual demands of large-scale production and precision quality control. With the rapid development of artificial intelligence, machine learning can deeply analyze multidimensional data of the morphology, spectroscopy, and chemical fingerprints of decoction pieces by constructing high-dimensional feature space analysis models, significantly improving the standardization level and decision-making efficiency of quality evaluation. This article reviews the research progress in the application of machine learning in the processing, production, and rapid quality evaluation of TCM decoction pieces. It further analyzes current challenges in technological implementation and proposes potential solutions, offering theoretical and technical references to advance the digital and intelligent transformation of the industry.

OBJECTIVE: To investigate effectiveness of the bridge combined fixation system (BCFS) for Bado typeⅠchronic Monteggia fractures (CMF) in children. METHODS: A clinical data of 8 children with Bado type ⅠCMF, who were treated with the BCFS between November 2023 and February 2025, was retrospectively analyzed. There were 6 boys and 2 girls, with a mean age of 7.0 years (range, 4-12 years). The time from injury to operation ranged from 29 to 370 days (median, 68.5 days). Preoperative elbow range of motion was (111.3±17.9)° in flexion, (13.1±13.9)° in extension, (71.9±14.6)° in pronation, and (75.6±13.5)° in supination. Fracture healing time and postoperative complications were observed, and clinical outcomes were evaluated using the Mayo elbow performance score. RESULTS: All incisions healed by primary intention without infection, non-healing of the incision, or iatrogenic nerve injury. All children were followed up 4-18 months (mean, 10.3 months). At last follow-up, the elbow range of motion significantly improved to (142.5±2.7)° in flexion, (2.5±2.7)° in extension, (87.5±2.7)° in pronation, and (88.8±2.3)° in supination ( P<0.05). According to the postoperative Mayo elbow performance score, all cases were rated as excellent. Radiographic review showed no radial head dislocation, nonunion at the ulnar osteotomy site, or elbow stiffness, and no breakage of the BCFS or screw loosening. The fracture healing time ranged from 3 to 6 months, with a median of 4 months. CONCLUSION The BCFS was confirmed to be effective in the treatment of pediatric Bado type Ⅰ CMF, with good restoration of elbow function and the advantage of avoiding secondary implant removal surgery.

OBJECTIVE: To explore the expression regulation of lipid metabolism gene ABHD5 in testes. METHODS: Differential gene analysis was performed by integrating databases of TCGA and GTEx to identify the target gene ABHD5. The expression trends of ABHD5 gene in testicular carcinoma tissue were analyzed. Human testis single-cell atlases were obtained from the Human Protein Atlas and Male Health Atlas databases to determine the expression distribution of ABHD5 across different testicular cell types. Additionally, the GTEx database was utilized to visualize the expression pattern of ABHD5 in the testis, thereby enhancing the understanding of its transcriptional profile. The relationship between ABHD5 expression and age was assessed through integrated database analysis. Western blotting and immunofluorescence were performed to detect differential expressions of ABHD5 in testicular tissues of young and aged mice respectively. RESULTS: The TCGA database indicated that the expression of ABHD5 in human testicular carcinoma tissue was significantly lower than that in normal testicular tissue which showed a negative correlation with patient survival. ABHD5 was highly expressed in germ cells of the testis reveaked from Human Protein Atlas and Male Health Atlas databases. The stability of ABHD5 protein was crucial for testicular tissue, and its expression decreased with age. Furthermore, Western blot and immunofluorescence staining demonstrated that ABHD5 expression in the testicular tissue of aged mice was significantly lower than that in young mice. CONCLUSION ABHD5 plays an important role in testicular tissue, and may be inseparable from testicular tumors and reproductive aging. However, its mechanism of action remains to be further studied.

The current production of Chinese herbal decoction pieces faces several issues including strong subjectivity,unstable quality,low production efficiency,and a lack of intelligent systems.In order to expedite the intelligent transformation and upgrading of Chinese medicine processing,this paper delves deeply into the problems and challenges encountered in establishing a digital and intel-ligent production model for Chinese herbal pieces.Addressing the slow progress in fundamental research on traditional Chinese medi-cine processing mechanisms,the absence of online digital quality characterization techniques,the low level of production equipment in-telligence,and the lack of evaluation standards for high-quality decoction pieces,this paper proposes a"New Quality Productive Forces"formation approach driven by technological innovation.Through interdisciplinary integration methods,the paper explores the mechanisms of Chinese medicine processing in depth,clarifies the correlation between the processing procedures and the"medicinal properties-quality"relationship,and employs bionic sensing and artificial intelligence to achieve a holistic quality characterization of decoction pieces.Additionally,the use of cloud-edge collaborative big data systems is proposed to enhance intelligent upgrades of the production lines.The paper also aims to establish a high-quality decoction piece evaluation system integrating"physical-chemical-bio-logical"multimodal data fusion.This approach aims to steer the Chinese medicine processing towards becoming more efficient,precise,and sustainable,thereby promoting high-quality sustainable development of the Chinese herbal decoction industry and providing both theoretical and practical support for the modernization of traditional Chinese medicine.

In this study, CM-5 spectrophotometer and Heracles NEO ultra-fast gas-phase electronic nose were used to analyze the changes in color and odor of vinegar-processed Cyperi Rhizoma(VPCR) pieces. Various analysis methods such as DFA and partial least squares discriminant analysis(PLS-DA) were combined to identify different processing degrees and quantify the end point of processing. The results showed that with the increase in vinegar processing, the brightness parameter L~* of VPCR pieces decreased gradua-lly, while the red-green value a~* and yellow-blue value b~* initially increased and reached their maximum at 8 min of processing, followed by a gradual decrease. A discriminant model based on the color parameters L~*, a~*, and b~* was established(with a discrimination accuracy of 98.5%), which effectively differentiated different degrees of VPCR pieces. Using the electronic nose, 26 odor components were identified from VPCR samples at different degrees of vinegar processing. DFA and PLS-DA models were established for different degrees of VPCR pieces. The results showed that the 8-min processed samples were significantly distinct from other samples. Based on variable importance in projection(VIP) value greater than 1, 10 odor components, including 3-methylfuran, 2-methylbuty-raldehyde, 2-methylpropionic acid, furfural, and α-pinene, were selected as odor markers for differentiating the degrees of vinegar processing in VPCR. By combining the changes in color and the characteristic odor components, the optimal processing time for VPCR was determined to be 8 min. This study provided a scientific basis for the standardization of vinegar processing techniques for VPCR and the improvement of its quality standards and also offered new methods and ideas for the rapid identification and quality control of the end point of processing for other traditional Chinese medicine.

Based our previous work, twelve purine derivatives were designed and synthesized as dual modulators of GPR119 and DPP-4by conjugating the GPR119 activating and DPP-4 inhibiting fragments with the position 6 and 9 of purine core via an approach of merged pharmacophores. Compound 11, bearing 2-fluoro-4-methylsulphonyl anilide and cyanopyrrolidine moieties, exhibited the most potent GPR119 agonistic activities (EC₅₀ = 0.33 μmol·L^-1, IA = 71.1%) and DPP-4 inhibitory (58.4% inhibition at 10 μmol·L^-1, 21.2% inhibition at 1 μmol·L^-1) activities in the in vitro antidiabetic study. Subsequently, we performed studies on structure activity relationships and molecular docking to guide the further drug design.

OBJECTIVE: To compare the curative effect of panlong needling at Jiaji (EX-B 2) combined with western medication and western medication alone on motor dysfunction in patients with Parkinson's disease (PD) of liver and kidney deficiency. METHODS: A total of 98 patients with PD were randomly divided into an acupuncture and medication group (49 cases, 1 case dropped off) and a western medication group (49 cases,1 case was removed). The patients in the western medication group were given oral of levodopa and benserazide hydrochloride tablets, 125 mg each time, three times a day in the 1st week, and the dose was increased according to the needs of the patients' condition from the 2nd week until 250 mg each time, three times a day, for 16 consecutive weeks. On the basis of the same western medication treatment as the western medication group, panlong needling was applied at Jiaji (EX-B 2) from C₂ to L₅ in the acupuncture and medication group, once a day, 20 times as a course of treatment, for 4 consecutive courses. The scores of unified Parkinson's disease rating scale (UPDRS-Ⅲ, UPDRS-Ⅳ), TCM symptoms score, and 39-item Parkinson's disease questionnaire (PDQ-39) score were evaluated before treatment, after treatment and during follow-up of 1 month after treatment, respectively. The safety of the two groups was compared. RESULTS: After treatment and during follow-up, except the PDQ-39 score of the western medication group, the scores of UPDRS-Ⅲ, UPDRS-Ⅳ, TCM syndrome and PDQ-39 were lower than those before treatment in the two groups (P<0.05), and the scores of above indexes in the acupuncture and medication group were lower than those of the western medication group (P<0.05). The total incidence of adverse reactions in the acupuncture and medication group was 10.4% (5/48), which was lower than 29.2% (14/48) in the western medication group (P<0.05). CONCLUSION Panlong needling at Jiaji (EX-B 2) combined with western medication could significantly improve the motor dysfunction and clinical symptoms, improve the quality of life and has high safety, and the efficacy is superior to western medication alone.

Objective: To evaluate the safety and efficacy of catheter ablation in patients with new-onset atrial arrhythmia after surgical excision of left atrial myxoma. Methods: Nine patients with new onset atrial arrhythmia and a prior history of left atrial myxoma, who received surgical myxoma excision and catheter ablation between September 2014 and November 2019, were included in the present study. Baseline characteristics, procedural parameters during catheter ablation, severe perioperative adverse events, recurrence rate of arrhythmia and clinical prognosis were analyzed. Kaplan Meier survival analysis was used to define the maintenance rate of sinus rhythm after catheter ablation in this patient cohort. Results: Nine patients were included. The average age was (55.8 ± 9.1) years old (3 male), there were 3 patients (3/9) with paroxysmal atrial fibrillation (PAF) and 6 patients (6/9) with atrial flutter or atrial tachycardia (AFL or AT). Ablation was successful in all patients, there were no perioperative complications such as stroke, pericardial effusion, cardiac tamponade, vascular complications or massive hemorrhage. During a mean follow-up time of 40.0 (27.5, 55.5) months, sinus rhythm was maintained in six patients (6/9) after the initial catheter ablation. The overall sinus rhythm maintenance rate was 2/3. In addition, 1 out of the 3 AF patients (1/3) developed recurrence of AF at 3 month after ablation, and 2 out of the 6 AFL or AT patients (2/6) developed late recurrence of AF or AFL (19 months and 29 months after ablation), two out of three patients with recurrent AFs or AFL received repeated catheter ablation and one patient remained sinus rhythm post repeat ablation. Meanwhile, there was no recurrence of atrial myxoma, no death, stroke, acute myocardial infarction and other events during the entire follow-up period. Conclusions: Catheter ablation is a safe and feasible therapeutic option for patients with new-onset atrial arrhythmia after surgical excision of left atrial myxoma.

OBJECTIVETo study the effect of golden-hour body temperature bundle management strategy on admission temperature and clinical outcome in preterm infants with a gestational age of <34 weeks after birth.

METHODSThe preterm infants who were born in the delivery room of the West China Second University Hospital of Sichuan University and admitted to the department of neonatology of this hospital within 1 hour after birth from December 2015 to June 2016 and from January to May, 2017 were enrolled. The 173 preterm infants who were admitted from January to May, 2017 were enrolled as the intervention group and were given golden-hour body temperature bundle management. The 164 preterm infants who were admitted from December 2015 to June 2016 were enrolled as the control group and were given conventional body temperature management.

RESULTSThe intervention group had a significantly higher mean admission temperature than the control group (36.4±0.4°C vs 35.3±0.6°C; P<0.001). The incidence rate of hypothermia on admission in the intervention group was significantly lower than that in the control group (56.6% vs 97.6%; P<0.001). The intervention group had a significantly lower incidence rate of intracranial hemorrhage within one week after admission than the control group (15.0% vs 31.7%; P<0.05).

CONCLUSIONSGolden-hour body temperature bundle management for preterm infants within one hour after birth can reduce the incidence of hypothermia on admission and improve clinical outcome.
