Objective To explore the protective effect of exercise-induced metabolite-3 (EIM-3) on myocardial ischemia-reperfusion (I/R) injury and explore its underlying molecular mechanisms. Methods The physicochemical properties and half-life of EIM-3 were analyzed using the Human Metabolome Database (HMDB, https://hmdb.ca/). A primary rat cardiomyocyte hypoxia/reoxygenation (H/R) injury model was established. Cell apoptosis and viability were assessed using TUNEL assay and cell counting kit-8, respectively. Lactate dehydrogenase (LDH) levels in the cell culture supernatant were measured. Intracellular reactive oxygen species (ROS) levels were detected. Transcriptomic analysis was performed to identify potential signaling pathways and targets of EIM-3. Results Plasma levels of EIM-3 were elevated post-exercise. EIM-3 was characterized as a phospholipid small-molecule compound with a partition coefficient (logP) of 5.58 and a solubility (logS) of −7.6, indicating favorable lipophilicity and cell membrane permeability. In cardiomyocytes H/R injury modles, EIM-3 significantly inhibited apoptosis, increased cell viability, reduced intracellular ROS levels, and decreased LDH release (P＜0.01). Transcriptomic analysis suggested that EIM-3 exerts its protective function potentially by regulating glucose metabolim. Quantitative real-time polymerase chain reaction results confirmed that EIM-3 significantly upregulated the transcriptional level of pyruvate kinase M2 (PKM2) in a dose-dependent manner (P＜0.001). Conclusions EIM-3 protects cardiomyocytes against I/R injury by modulating glucose metabolim. This study provides foundational insights into the mechanisms underlying exercise-induced cardioprotection.

Objective To explore the feasibility and safety of using indocyanine green combined with autologous blood and methylene blue for localization of small lung nodules during thoracoscopic wedge resection. Methods Patients who underwent CT-guided percutaneous lung puncture injection of localization agents to locate lung nodules at the First Affiliated Hospital of Fujian Medical University from November 2023 to January 2024 were selected. Under thoracoscopy, lung nodules were located by white light mode, fluorescence mode, or near-infrared mode and wedge resection was performed. The feasibility of using indocyanine green combined with autologous blood and methylene blue for localization of small lung nodules was preliminarily verified by evaluating whether the localization agent concentrated around the nodules, and the safety of this method was verified by analyzing the incidence of adverse reactions during patient puncture and surgery. Results A total of 30 patients with lung nodules were included, including 10 males and 20 females, with an average age of (55.5±11.2) years. In 26 patients, the amount of localization agent used was moderate, the localization agent concentrated around the nodules, and successful precise localization of small lung nodules was achieved. In 4 patients, due to excessive use of localization agent, the marker was diffuse with pleural staining. The overall localization success rate was 86.7%, and when the injection volume of localization agent was 0.2-0.5 mL, the localization success rate was 100.0%. All patients successfully completed thoracoscopic wedge resection and found nodule lesions, with negative margins and a distance from the margin to the lesion that met the requirements. There were no complications. Conclusion Thoracoscopic surgery using indocyanine green combined with autologous blood and methylene blue for localization of small lung nodules is safe and feasible.

Objective To investigate the prognosis and satisfaction of the R2 intervention procedure and develop related predictive models. Methods The clinical data of 64 patients with primary craniofacial hyperhidrosis who underwent R2 intervention surgery at the First Affiliated Hospital of Fujian Medical University from November 2018 to October 2022 were retrospectively analyzed. By statistically analyzing the risk factors for compensatory hyperhidrosis (CH) and satisfaction, and conducting feature screening, a relevant prediction model was established. Results Finally, 51 patients were collected, including 43 (84.3%) males and 8 (15.7%) females, with an average age of (30.27±7.22) years. Overall postoperative satisfaction was high, with only 5.9% of patients expressing regret about the surgery. However, 92.2% of patients experienced CH. The onset of postoperative CH was most prominent within the first 3 months postoperatively, with the incidence rate stabilizing thereafter. Preoperative heart rate and R2 sympathetic nerve clipping were identified as independent risk factors for severe CH. The preoperative body mass index, the degree of sweating in the chest and abdomen, are significantly correlated with postoperative satisfaction. Conclusion The R2 intervention surgery effectively alleviates the symptoms of primary craniofacial hyperhidrosis, and patient satisfaction is high.

BACKGROUND:Traditional scoliosis orthosis has some disadvantages,such as complex manufacturing process,long processing cycle,poor fit and so on.Three-dimensional printed scoliosis orthosis has the advantages of high manufacturing precision and personalization. OBJECTIVE:To evaluate the efficacy of three-dimensional printed scoliosis orthosis for scoliosis based on multi-criteria decision model. METHODS:Clinical data of 72 patients with scoliosis admitted to Chen Xinghai Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to October 2022 were retrospectively collected and divided into two groups according to the treatment of orthosis.Study group(n=23)received three-dimensional printed scoliosis orthosis.Traditional group(n=49)received the traditional polypropylene spine brace treatment.The clinical efficacy and complications were compared between the two groups.A multi-criteria decision model for the treatment of scoliosis with three-dimensional printed scoliosis orthosis was established,and the stability of the benefit value,risk value and decision model of the two groups were evaluated. RESULTS AND CONCLUSION:(1)Compared with the traditional group,there were significant differences in the top vertebral offset distance,Cobb angle,top vertebral rotation,Functional Movement Screen score,visual analog scale score and total effective rate in the study group at 6 months after surgery(P<0.05).(2)Among the benefit indexes,Cobb angle had the greatest impact on the condition of patients,while the risk indexes had the greatest impact on dyspnea.(3)The benefit values of the study group and the traditional group for scoliosis were 79 and 64,and the risk values were 74 and 57,respectively.The combined benefit and risk values found that the benefit-risk value of the study group was 16 higher than that of the traditional group.(4)In the range of 0-100%relative risk weight,the benefit-risk value of the study group was always higher than that of the traditional group,which proved that the multi-criteria decision-making model had good stability.(5)It is indicated that three-dimensional printed scoliosis orthosis can better restore the physiological curvature of scoliosis and improve the efficiency of treatment.

From the perspectives of traditional Chinese medicine （TCM） information knowledge base and assisted decision-making knowledge base， the construction status， quality evaluation status and existing problems of current TCM knowledge bases have been sorted out. And based on the quality evaluation strategies and dimensions of know-ledge bases in other disciplines， the evaluation indexes for TCM knowledge base is discussed， and the evaluation framework is initially formed， providing ideas for the improvement of the TCM knowledge base evaluation system. In terms of the evaluation indexes， there are basic evaluation dimensions which include data sources， data collection， and data application. The specific evaluation dimension of the information-based knowledge base is data quality， while that of the assisted decision-making knowledge base is data matching. Except for the data application dimension which counts the valid data items in the database for calculation， other indexes are scored based on the qualitative evaluation of "yes"， "no" or "unknown". The basic evaluation score and the specific evaluation score are added to obtain the total score. The knowledge base is graded according to the score， and the results are presented in the form of grade plus number.

A 11-year old female patient with severe thalassemia, receipt a lentivirus-based cell and gene therapy (CGT) therapy in Shenzhen Children′s Hosptial on July 27th, 2021. At the two follow-up visits after discharge, patient were continuously tested positive for HIV screening through HIV Ag/Ab Combo assay (chemiluminescence Immunoassay), and the viral load results of HIV-1 nucleic acid testing (NAT) were both>5 000 copies/ml. The patient can be diagnosed with HIV infection according to the National Guideline for Detection of HIV/AIDS(2020 Revised Edition). The thorough investigation findings and supplementary experiment results indicated that the false-positive HIV-1 NAT results was caused by cross-reactivity between the target sites detected by conventional HIV-1 NAT reagents and the lentiviral vectors fragments integrated into the genome of patient′s hematopoietic stem/progenitor cells. In conclusion, it is important for laboratories to select appropriate HIV-1 NAT testing platforms which won′t cause cross-reactivity for the testing of samples from patients who have been treated with HIV-derived vectors. It is also recommended to design and develop NAT testing platforms with multiple target regions labeled by different fluorescents for HIV NAT supplementation experiment to reduce the risk of false-positive diagnoses of HIV infection.

Objective: To investigate the effect of Guangdong Shenqu (GSQ) on intestinal flora structure in mice with food stagnation through 16S rDNA sequencing. Methods: Mice were randomly assigned to control, model, GSQ low-dose (GSQL), GSQ medium-dose (GSQM), GSQ high-dose (GSQH), and lacidophilin tablets (LAB) groups, with each group containing 10 mice. A food stagnation and internal heat mouse model was established through intragastric administration of a mixture of beeswax and olive oil (1:15). The control group was administered normal saline, and the model group was administered beeswax and olive oil to maintain a state. The GSQL (2 g/kg), GSQM (4 g/kg), GSQH (8 g/kg), and LAB groups (0.625 g/kg) were administered corresponding drugs for 5 d. After administration, 16S rDNA sequencing was performed to assess gut microbiota in mouse fecal samples. Results: The model group exhibited significant intestinal flora changes. Following GSQ administration, the abundance and diversity index of the intestinal flora increased significantly, the number of bacterial species was regulated, and α and β diversity were improved. GSQ administration increased the abundance of probiotics, including Clostridia, Lachnospirales, and Lactobacillus, whereas the abundance of conditional pathogenic bacteria, such as Allobaculum, Erysipelotrichaceae, and Bacteroides decreased. Functional prediction analysis indicated that the pathogenesis of food stagnation and GSQ intervention were primarily associated with carbohydrate, lipid, and amino acid metabolism, among other metabolic pathways. Conclusion The digestive mechanism of GSQ may be attributed to its role in restoring diversity and abundance within the intestinal flora, thereby improving the composition and structure of the intestinal flora in mice and subsequently influencing the regulation of metabolic pathways.

Consumptive thirst is widely discussed in Huangdi Neijing and it is classified as a"strange disease"in Suwen·Strange Diseases Treatise,which reflects the intractable nature of consumptive thirst.This paper explores and analyzes consumptive thirst based on the core concept in Huangdi Neijing.First,this paper approaches the subject through the use of image thinking method from Huangdi Neijing,recognizing that consumptive thirst can lead to changes in the internal climate of the human body.Then,guided by the theories of essence and qi,yin and yang,and the five elements in Huangdi Neijing,it deconstructs and analyzes the causes of these changes and the laws of qi transformation.It points out that the changing climate of consumptive thirst is characterized by"heat symptoms".The main cause of"heat symptoms"is spleen deficiency and excessive dampness,and its qi transformation law is the heat transformation of Shaoyin.The intractable nature of consumptive thirst is mainly reflected in the uncontrolled"heat symptoms"caused by the imbalance of the five elements.Based on the understanding of the heat symptoms of consumptive thirst,this paper proposes a treatment strategy for preventing the disease by resolving dampness and regulating the spleen,harmonizing kidney qi to prevent progression,and balancing yin and yang to treat chronic and recalcitrant conditions.The aim is to provide a reference for optimizing the treatment of consumptive thirst.

OBJECTIVE To evaluate the therapeutic efficacy and safety of vonoprazan-based triple therapy in treatment-naive patients with Helicobacter pylori （Hp） infection. METHODS From March 2022 to August 2023， 198 treatment-naive patients with Hp infection treated at the outpatient service of department of gastroenterology in our hospital were assigned to the vonoprazan- based triple therapy group （VAC group， n＝98） and the bismuth-based quadruple therapy group （BQT group， n＝100） using the random number table method. Patients in VAC group were given Vonoprazan fumarate tablets （20 mg） + Amoxicillin capsules （1 g） + Clarithromycin tablets （0.5 g）， all twice daily. Patients in BQT group were given Esomeprazole magnesium enteric-coated tablets （20 mg， twice daily） + Metronidazole tablets （0.4 g， four times daily） + Tetracycline tablets （0.5 g， three times daily） + Bismuth potassium citrate capsules （0.6 g， twice daily）. The treatment course for both groups was 14 days. The Hp eradication rates were compared between the two groups in intention-to-treat （ITT）， modified intention-to-treat （MITT）， and per-protocol （PP） analysis sets， while adverse reaction occurrence and medication compliance of two groups were recorded. RESULTS In the ITT， MITT and PP analyses sets， the Hp eradication rates in VAC group were non-inferior to those in BQT group. The incidences of grades 1-2 nausea， vomiting， and loss of appetite in VAC group were significantly lower than in BQT group， and the proportion of patients with good compliance was significantly higher in VAC group （P＜0.05）. Regardless of whether the body mass index （BMI） ≤25 kg/m2 or ＞25 kg/m2， no statistically significant difference was observed in the Hp eradication rates between the two groups （P＞0.05）. CONCLUSIONS Vonoprazan-based triple therapy is non-inferior to bismuth-based quadruple therapy in the treatment of treatment-naive patients with Hp infection， with higher safety and good patient medication compliance. BMI has no significant impact on the Hp eradication rate.
