BACKGROUND:It has been found that mitochondrial function is abnormal in patients with chronic fatigue syndrome,and the administration of coenzymes can improve the symptoms.Warm acupuncture is one of the most important treatments for this disease,but its mechanism of action is unclear. OBJECTIVE:To investigate the effects of warm acupuncture on the phosphatase and tensin inducible kinase 1(PINK1)/Parkin pathway in the skeletal muscle of rats with chronic fatigue syndrome. METHODS:After 3 days of adaptive feeding,32 male Sprague-Dawley rats were randomly divided into normal control,model,warm acupuncture,and coenzyme Q groups with 8 rats in each group.The chronic fatigue syndrome model was established by multiple factors,including swimming exhaustion,chronic immobilization and fasting.After successful modeling,the normal group and the model group were treated with the same fixation and gavage procedures,and the warm acupuncture group was treated with acupuncture at Guanyuan,Zhongwan and Zusanli(bilateral)points,once a day.After the needling was inserted,the moxa pillar was put on the needle handle and ignited,three sessions once.The coenzyme Q group was given 1 mL/kg coenzyme by gavage,once a day for 14 days.The body mass,exhaustive swimming time and food utilization rate during the treatment were recorded.After the treatment,the bilateral gastrocnemius muscles of rats in each group were collected.The pathological morphology of the gastrocnemius muscle was observed by hematoxylin-eosin staining,the mitochondrial morphology and autophagosome of the gastrocnemius muscle were observed by transmission electron microscope.The expression level of microtubule-associated protein light chain 3(LC3)Ⅱ protein in the skeletal muscle was detected by immunohistochemistry.Western blot was used to detect the expression of PINK1,Parkin,LC3 Ⅰ,and LC3 Ⅱ in the skeletal muscle. RESULTS AND CONCLUSION:Compared with the normal group,the gastrocnemius muscle nuclei of the model group were pyknotic,condensed,the number of cells was increased,the cells were arranged disorderly,and the fibers in the gastrocnemius muscle were tightly arranged in the model group.Compared with the model group,the intercellular space became smaller,the nuclei were reduced,and the cell arrangement was orderly in the warm acupuncture group and coenzyme Q group.Compared with the normal group,the skeletal muscle mitochondria in the model group were swollen,fused,and vacuolated seriously,the membrane was partially broken,the matrix was more dissolved,the cristae was broken and disappeared,and autophagy appeared.Compared with the model group,the number of mitochondria increased,the arrangement was relatively neat,mitochondrial vacuolization and rupture of cristae in the gastrocnemius muscle were improved,the membrane structure was relatively intact,and autophagy occurred.Compared with the normal group,the expression of PINK1 protein in the skeletal muscle of the model group was significantly increased(P<0.05),while the expression of Parkin,LC3 Ⅱ and LC3 Ⅱ/Ⅰ protein was slightly upregulated(P>0.05).Compared with the model group,the protein expressions of PINK1,Parkin,LC3 Ⅱ and LC3 Ⅱ/Ⅰ were significantly upregulated in the warm acupuncture and coenzyme Q groups(P<0.05),and the up-regulation was more significant in the warm acupuncture group.To conclude,warm acupuncture can play a role in the treatment of chronic fatigue syndrome by activating the PINK1/Parkin pathway,upregulating LC3 Ⅱ expression,forming mitochondrial autophagosomes,promoting the degradation of damaged mitochondria,and improving mitochondrial quality.

OBJECTIVE To evaluate the efficacy and safety of letermovir in preventing cytomegalovirus （CMV） infection after allogeneic hematopoietic stem cell transplantation （allo-HSCT）. METHODS A retrospective cohort study was conducted， enrolling patients who underwent allo-HSCT at the Department of Hematology， Shanghai General Hospital Affiliated to Shanghai Jiao Tong University School of Medicine， from August 30， 2022， to February 21， 2024. Patients who initiated letermovir prophylaxis within 28 days post-transplantation were assigned to the experimental group （99 cases）， while those who did not initiate letermovir within this period were assigned to the control group （18 cases）. The incidence and clinical characteristics of CMV infection （including the number of wangranran@xinhuamed.com.cn CMV infection cases， the number of cases progressing to CMV disease， recurrent CMV disease， onset time of CMV infection， and treatment duration）， immune function recovery within 120 days post-transplantation， and the occurrence of transplantation-related complications （including CD4+ and CD8+ T-cell recovery， Epstein-Barr virus infection， acute graft-versus-host disease， human herpesvirus 6 infection， and posttransplant lymphoproliferative disorders） and adverse events were recorded. Univariate and multivariate Cox regression analyses were performed to identify factors influencing CMV infection. RESULTS A total of 117 patients were included， among whom 15 developed CMV infection， 5 progressed to CMV disease， and 2 experienced recurrent CMV disease. The CMV infection rate in the experimental group was significantly lower than that in the control group （P＜0.001）， and the onset time of CMV infection was significantly delayed （P＝0.014）. The proportion of patients with CD4+ T-cell counts ≥200 cells/μL in the experimental group was significantly lower than that in the control group （P＝0.022）. During the follow-up period， elevated creatinine levels were observed in 1 patient， and nausea and vomiting were observed in 2 patients. Multivariate Cox regression analysis revealed that the use of high-dose corticosteroids was a risk factor for CMV infection （HR＝6.230， 95%CI of 1.255-30.926， P＝0.025）， while initiating letermovir within 28 days post-transplantation was a protective factor （HR＝0.125， 95%CI of 0.045-0.348， P＜0.001）. CONCLUSIONS Early initiation of letermovir after allo-HSCT significantly reduces the CMV infection rate and delays the onset of infection， with favorable short-term safety.

Objective: To investigate the detection of natural infection with pathogens in rodents in Huzhou City, Zhejiang Province, so as to provide a basis for risk assessment and control of rodent-borne diseases. Methods: From August to September each year during the period of 2022-2024, urban residential areas, rural residential areas, key industries, farmland and cultivated land, forests, and shrublands in various counties (districts) of Huzhou City were selected as rodent surveillance sites. Rodents were captured using the trap night method. Following anesthesia, the rodents were euthanized by cervical dislocation. Species were identified based on morphological characteristics. Under sterile conditions, dissection was performed to collect liver, spleen, lung, and kidney tissues. These tissues were then mixed together, and detected for Hantavirus, Dabie bandavirus, Leptospira, and Orientia tsutsugamushi using fluorescence quantitative PCR. The detection rates of these natural infections with pathogens were analyzed across different rodent species, counties (districts), and habitats. Results: A total of 259 rodents were captured from 2022 to 2024, including Rattus norvegicus, Rattus tanezumi, Suncus murinus, Mus musculus, Leopoldamys edwardsi, Niviventer fulvescens, Rattus losea, and Apodemus agrarius. The dominant species were Rattus norvegicus (142 individuals) and Rattus tanezumi (59 individuals), collectively accounting for 77.61%. With the exception of Orientia tsutsugamushi, Hantavirus, Dabie bandavirus, and Leptospira were all detected, with detection rates of 5.02%, 1.93%, and 10.42%, respectively. Hantavirus and Leptospira were simultaneously detected in one Rattus norvegicus, yielding a mixed infection rate of 0.39%. The three pathogens were detected in rodents in Wuxing District, Nanxun District, Deqing County, Changxing County, and Anji County, with detection rates of 6.45%, 5.71%, 26.32%, 4.76%, and 24.00%, respectively. They were also detected in rodents in urban residential areas, rural residential areas, key industries, farmland, and forests, with detection rates of 28.57%, 21.57%, 10.91%, 12.50%, and 14.81%, respectively. Notably, all three pathogens were simultaneously detected in Rattus norvegicus, Rattus tanezumi, rural residential areas, and key industries. Conclusions Rattus norvegicus and Rattus tanezumi were identified as the dominant rodent species in Huzhou City. The detection of Hantavirus, Dabie bandavirus, and Leptospira, including instances of mixed infection. It is necessary to enhance surveillance and control measures targeting these key species and high-risk habitats.

The innate immune response is the first line of defense for the host against viral infections. Targeted degradation of pathogenic microorganisms through autophagy, in conjunction with pattern recognition receptors synergistically inducing the production of interferon (IFN), constitutes an important pathway for the body to resist viral infections. Rubicon, a Run domain Beclin 1-interacting and cysteine-rich domain protein, has an inhibitory effect on autophagy and IFN production. On the one hand, Rubicon, as a component of the phosphoinositide 3-kinase (PI3K) complex, interacts with different domains of vacuolar protein sorting 34 (Vps34), ultraviolet radiation resistance associated gene (UVRAG), guanosine triphosphate (GTP) kinase, and RAS oncogene family member 7 (Rab7) to mediate the inhibition of autophagy maturation; on the other hand, Rubicon inhibits the ubiquitination of nuclear factor κB essential modulator (NEMO) and the dimerization of interferon regulatory factor 3 (IRF3), thereby blocking the signal transduction related to IFN production. Research has revealed that various viruses, such as Kaposi's sarcoma-associated herpesvirus (KSHV), hepatitis B virus (HBV), Sendai virus (SeV), and hepatitis C virus (HCV), achieve innate immune evasion by regulating the expression or function of Rubicon. Rubicon is expected to be a new target for antiviral therapy.

"Weibing" is a fundamental concept in traditional Chinese medicine (TCM), representing a transitional state characterized by diminished self-regulatory abilities without overt physiological or social dysfunction. This perspective delves into the biological foundations and quantifiable markers of Weibing, aiming to establish a research framework for early disease intervention. Here, we propose the "Health Quadrant Classification" system, which divides the state of human body into health, sub-health, disease-susceptible state, and disease. We suggest the disease-susceptible stage emerges as a pivotal point for TCM interventions. To understand the intrinsic dynamics of this state, we propose laboratory and clinical studies utilizing time-series experiments and stress-induced disease susceptibility models. At the molecular level, bio-omics technologies and bioinformatics approaches are highlighted for uncovering intricate changes during disease progression. Furthermore, we discuss the application of mathematical models and artificial intelligence in developing early warning systems to anticipate and avert the transition from health to disease. This approach resonates with TCM's preventive philosophy, emphasizing proactive health maintenance and disease prevention. Ultimately, our perspective underscores the significance of integrating modern scientific methodologies with TCM principles to propel Weibing research and early intervention strategies forward.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objectives:To investigate the application value of laparoscopic double stapler firings and double stapling technique combined with rectal eversion and total extra-abdominal resection (LDER) in the anal preservation treatment of low rectal cancer.Methods:Inclusion criteria: (1) age was 18-70; (2) the distance of the lower tumor edge from the anal verge was 4-5 cm; (3) primary tumor with a diameter ≤3 cm; (4) preoperative staging of T1~2N1~2M0; (5) "difficult pelvis", defined as ischial tuberosity diameter<10 cm or body mass index>25 kg/m 2; (6) patients with strong intention for sphincter preservation; (7) no preoperative treatment (e.g., chemotherapy, radiotherapy, molecular targeted therapy, or immunotherapy); (8) no lateral lymph node enlargement; (9) no previous anorectal surgery; (10) patients with good basic condition who could tolerate surgery. Exclusion criteria: (1) previously suffered from malignant tumors of the digestive tract or currently suffering from malignant tumors out of the digestive tract; (2) patients with preoperative anal dysfunction (Wexner score ≥ 10), or fecal incontinence. The specific surgical steps are as follows: the distal end of the rectum was dissected to the level of the interspace between internal and external sphincters of anal canal. Five centimeters proximal to the tumor, the mesorectum was ligated, and a liner stapler was used to transect the rectum. The distal rectum with the tumor were then everted and extracted through the anus. The rectum was transected 0.5-1.0 cm distal to the tumor with a linear stapler. Full thickness suture was used to reinforce the stump of the rectum, which was then brought back into the pelvic cavity. Finally, an end-to-end anastomosis between the colon and the rectum was performed. A retrospective descriptive study was performed of the clinical and pathological data of 12 patients with T1-T2 stage low rectal cancer treated with LDER at Henan Provincial People's Hospital from January 2020 to December 2022. Results:All 12 patients successfully completed LDER with sphincter preservation, without conversion to open surgery or changes in surgical approach. The median surgical time was 272 (155-320) minutes, with a median bleeding volume of 100 (50-200) mL. No protective stoma was performed, and all patients received R0 resection. The average hospital stay was 9 (7-15) days. There were no postoperative anastomotic leakage or perioperative deaths. All 12 patients received postoperative follow-up, with a median follow-up of 12 months (6-36 months) and a Wexner score of 8 (5-14) at 6 months postoperatively. There was no tumor recurrence or metastasis during the follow-up period.Conclusions:LDER is safe and effective for the treatment of low rectal cancer.

OBJECTIVE To explore the application value of indocyanine green combined with near-infrared autofluorescence imaging technique in identifying pathological parathyroid glands during surgery for primary hyperparathyroidism (PHPT). METHODS Data from 40 patients with PHPT treated in Beijing Tongren Hospital,Capital Medical University were collected,including 10 patients in the indocyanine green treated group and 30 patients in the non-treated group. All patients underwent surgical treatment to remove the affected parathyroid glands. Near-infrared autofluorescence imaging was used for image acquisition,and ImageJ software was used for fluorescence intensity analysis. RESULTS The fluorescence intensity of the pathological parathyroid glands in the indocyanine green-treated group was significantly higher than that in the non-treated group(142.7±23.7 vs. 94.5±31.4,t=-4.434,P=0.000);the fluorescence ratio of pathological parathyroid glands/thyroid glands was significantly higher than that in the non-treated group(1.6±0.3 vs. 1.2±0.4,t=-3.162,P=0.004). There was no correlation between the fluorescence intensity of parathyroid glands in the non-treated group and preoperative blood calcium(r=0.029,P=0.088) and preoperative PTH level(r=-0.142,P=0.455),and there was also no correlation between the fluorescence intensity of parathyroid glands in the treated group and preoperative blood calcium(r=0.206,P=0.568) and preoperative PTH level(r=0.160,P=0.658). The detection rate of near-infrared light in the non-treated group was 53.3％(16/30),while that in the treated group was 100％(10/10). The average detection time for the non-treated group was (71.0±16.9)minutes,while that for the treated group was (52.7±11.1)minutes,with a significant difference between the two groups(t=3.187,P=0.003). CONCLUSION The combination of indocyanine green and near-infrared autofluorescence imaging technique is helpful for identifying the diseased parathyroid glands during the surgical treatment of PHPT.

Objective:To explore the medication law of gilles de la Tourette syndrome (TS) in ancient TCM books through data mining.Methods:TS related disease information was searched by searching Chinese Medicine Collection Database 4.0 and Chinese Medical Classics 5.0 about liver wind, convulsion, infantile convulsion, slow infantile convulsion, Chi Zong, Jin Ti Rou Yu, chronic spleen wind. Excel 2022 software was used to input the main symptoms, etiology and pathogenesis, treatment methods and prescriptions of each disease, and the frequency, property and taste, meridian tropism and efficacy of medication were analyzed. Gephi 0.9.2 software was used to analyze the complex network of Chinese materia medica data to find out the core drugs. SPSS Statistic 25.0 software was used for clustering analysis of high-frequency Chinese materia medica (top 50 in frequency ). SPSS Modeler 14.2 software was used to analyze the association rules of high-frequency Chinese materia medica based on Apriori algorithm. Results:Totally 692 ancient prescriptions were included, involving 436 kinds of Chinese materia medica. The top five in terms of frequency were: Scorpio, Cinnabaris, Moschus, Typhonii Rhizoma, Gastrodiae Rhizoma appeared the most frequently. The main property was cold, the main taste was pungent, and mainly into the liver, spleen, and heart meridians; the core drugs were Bombyx Batryticatus, Pinelliae Rhizoma, and Glycyrrhizae Radix et Rhizoma. Clustering analysis could be divided into 8 categories. Correlation analysis showed that Scorpio→Bombyx mori Linnaeus and Cinnabaris had the highest support, while Cinnabaris→Bovis Calculus→Moschus→Scorpio had the highest confidence.Conclusions:Ancient doctors believed that the disease location of TS-related diseases are mainly liver, heart, spleen and kidney, and the pathogenic factors were mainly wind, fire, phlegm, blood stasis and deficiency. The insect snakes used in prescription drugs are used to search for wind and eliminate pathogenic factors, the epigraphy is used to calm the nerves and calm the wind, and the herbs are used to soothe the wind, clear heat, calm the liver and dispel phlegm.
