Objective:To investigate the feasibility and safety of implementing a domestic vehicle-mounted remote mobile robotic surgical system in thyroid surgery applications, integrated with 5G communication technology.Methods:Using the main system located on the vehicle-mounted mobile robot operating platform of the 960th Hospital of PLA Joint Logistics Support Force and the slave system of Weifang Traditional Chinese Hospital, the remote radical thyroidectomy 5G communication technology, and analyze the clinical and information transmission data of two female patients who underwent remote mobile robot thyroid cancer surgery on October 21, 2024 at Weifang Traditional Chinese Medicine Hospital.Results:The remote radical thyroidectomy was conducted by the robosurgeons utilizing a vehicle-mounted mobile robotic surgical system, and the procedure was successfully completed without necessitating intermediate open surgery. The operation durations for patient 1 and patient 2 were 135 minutes and 108 minutes, respectively, with 7 and 13 lymph nodes dissected, respectively. The average delay in surgical data transmission was recorded at 61.9 milliseconds, with no instances of signal interruption or frame loss. The procedure proceeded smoothly, without any jamming, and the audio and video transmissions were consistently clear. Follow up for 21 days after surgery showed no complications such as hoarseness, skin damage, or lymphatic fistula.Conclusion:The implementation of a vehicle-mounted remote mobile robotic surgery system for thyroid surgery has demonstrated safety and feasibility. Furthermore, the utilization of the 5G network offers rapid data transmission and minimal latency, closely approximating the therapeutic efficacy of traditional robotic thyroidectomy.

Objective:To explore the spousal correlations of total cholesterol(TC),total triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C),and to investigate the reasons behind these spousal correlations.Methods:Participants and data were from the baseline survey of family-based cohort studies in Fangshan,Beijing and Tulou,Fujian.The ori-gin of spousal correlations were explored from perspectives of convergence,assortative mating,social ho-mogamy.Pearson's correlation and generalized linear models(GLM)were used to estimate the spousal correlation.Convergence was assessed by Pearson's correlation between the phenotypic differences be-tween couples and the duration of marriage,with GLM used for further validation.Pearson's correlation of genetic risk scores(GRS)and couple-specific Mendelian randomization(MR)were calculated to assess the genetic correlation and possible causal relationships between spouses.Two-independent-sample t-tests were used to compare GRS consistency across subgroups divided by education attainment,couple-specific MR and Q statistics used to test assortative mating in subgroups and intergroup differences.Results:In the study,342 couples(287 couples from Fangshan and 55 couples from Fujian)were included,with the average age of(64.91±8.76)years.Spousal correlations of TC,TG,HDL-C,and LDL-C showed statistically significant associations both before and after adjusting for covariates,with effect sizes of 0.229(95％CI:0.125-0.327),0.257(95％CI:0.155-0.354),0.179(95％CI:0.074-0.280),and 0.181(95％CI:0.076-0.282).For convergence,for each additional year of marriage,ΔTC increased by 0.016 mmol/L(95％CI:0.001-0.033 mmol/L),and ΔLDL-C increased by 0.017 mmol/L(95％CI:0.002-0.031 mmol/L).For assortative mating,GRS correlations and results of couple specific MR didn't show any statistical significance.For social homogamy,no differences in GRS or assortative mating were found between subgroups stratified by education attainment.Conclusion:The blood lipid in participants exhibit spousal phenotypic correlations,however,no effects of convergence,assortative mating or social homogamy were observed.More independent studies with larger sample sizes are warranted to further validate these findings in the future.

BACKGROUND:Developed by the esteemed Chinese medicine master Wei Guikang,Tongan Decoction has proven highly effective in treating knee osteoarthritis.However,the mechanism of action is yet unclear.OBJECTIVE:To elucidate how Tongan Decoction modulates synovial macrophage polarization as a therapeutic strategy for knee osteoarthritis in a rat model.METHODS:(1)We employed high-throughput microRNA sequencing and polymerase chain reaction to analyze the differentially expressed miRNA in synovial macrophages of normal and knee osteoarthritis rats.Predicted target genes of miR-27a were identified using bioinformatics databases,with subsequent validation through luciferase assays.A total of 68 Sprague-Dawley rats were randomly divided into normal control group(n=16),model group(n=16),miR-27a overexpression group(n=12),Tongan Decoction group(n=12),and Tongan Decoction+miR-27a inhibition group(n=12).The miR-27a overexpression group and the Tongan Decoction+miR-27a inhibition group were injected with miR-27a mimic and miR-27a inhibitor in the right knee joint cavity,respectively,once daily for 5 continuous days.On the 15th day after modeling,the Tongan Decoction group and the Tongan Decoction+miR-27a inhibition group were given Tongan Decoction by gastric lavage,and the other three groups were given saline by gastric lavage,once daily for 14 continuous days.After administration,behavioral tests,X-rays,hematoxylin-eosin staining of synovial and cartilage tissues of the knee joint and immunofluorescence staining of synovial tissues of the knee joint,RT-PCR,and Western blot were performed.RESULTS AND CONCLUSION:High-throughput sequencing of miRNA showed low expression of miR-27a in synovial tissues of rats with knee osteoarthritis.The target gene of miR-27a was nuclear factor κB,and luciferase assay showed that the two could bind to each other.Behavioral assays showed that miR-27a overexpression or Tongan Decoction alleviated joint dysfunction in rats with knee osteoarthritis,and miR-27a inhibition antagonized the effect of Tongan Decoction.X-ray films and hematoxylin-eosin staining showed that miR-27a overexpression or Tongan Decoction reduced the degree of knee osteoarthritis and miR-27a inhibition weakened the therapeutic effect of Tongan Decoction.The results of RT-PCR and western blot assay showed that compared with the normal control group,the expression of interleukin 10 was reduced in the model group(P＜0.05),and the expression of matrix metalloproteinase 13,interleukin 1β,and nuclear factor κB was elevated in the model group(P＜0.05).miR-27a overexpression or Tongan Decoction could differently reverse the changes in the above-mentioned indexes,while miR-27a inhibition weakened the effect of Tongan Decoction.Immunofluorescence staining results showed that CD86 protein expression in the model group was higher than that in the normal control group(P＜0.05),and CD206 protein expression was lower than that in the normal control group(P＜0.05);miR-27a overexpression group and Tongan Decoction had lower CD86 protein expression than that in the model group(P＜0.05),and higher CD206 protein expression than that in the model group(P＜0.05);in the Tongan Decoction+miR-27a inhibition group,CD86 protein expression was higher(P＜0.05)and CD206 protein expression was lower than that in the Tongan Decoction group(P＜0.05).Tongan Decoction mitigates knee osteoarthritis by upregulating miR-27a expression and suppressing nuclear factor κB activity,which improves knee joint function and further treats knee osteoarthritis.

Objective:Rejection remains the most important factor limiting the survival of transplanted kidneys.Although a pathological biopsy of the transplanted kidney is the gold standard for diagnosing rejection,its limitations prevent it from being used as a routine monitoring method.Recently,peripheral blood lymphocyte subpopulation testing has become an important means of assessing the body's immune system,however,its application value and strategy in the field of kidney transplantation need further exploration.Additionally,the development and utilization of routine test parameters are also important methods for exploring diagnostic strategies and predictive models for kidney transplant diseases.This study aims to explore the correlation between peripheral blood lymphocyte subpopulations and T cell-mediated rejection(TCMR)and antibody-mediated rejection(ABMR),as well as their diagnostic value,in conjunction with routine blood tests. Methods:A total of 154 kidney transplant recipients,who met the inclusion and exclusion criteria and were treated at the Second Xiangya Hospital of Central South University from January to December,2021,were selected as the study subjects.They were assigned into a stable group,a TCMR group,and an ABMR group,based on the occurrence and type of rejection.The basic and clinical data of these recipients were retrospectively analyzed and compared among the 3 groups.The transplant kidney function,routine blood tests,and peripheral blood lymphocyte subpopulation data of the TCMR group and the ABMR group before rejection treatment were compared with those of the stable group. Results:The stable,TCMR group,and ABMR group showed no statistically significant differences in immunosuppressive maintenance regimens or sources of transplanted kidneys(all P>0.05).However,the post-transplant duration was significantly longer in the ABMR group compared with the stable group(P<0.001)and the TCMR group(P<0.05).Regarding kidney function,serum creatinine levels in the ABMR group were higher than in the stable group and the TCMR group(both P<0.01),with the TCMR group also showing higher levels than the stable group(P<0.01).Both TCMR and ABMR groups had significantly higher blood urea nitrogen levels than the stable group(P<0.01),with no statistically significant difference between TCMR and ABMR groups(P>0.05).The estimated glomerular filtration rate(eGFR)was lower in both TCMR and ABMR groups compared with the stable group(both P<0.01).In routine blood tests,the ABMR group had lower hemoglobin,red blood cell count,and platelet count than the stable group(all P<0.05).The TCMR group had higher neutrophil percentage(P<0.05)and count(P<0.05)than the stable group,and the ABMR group had a higher neutrophil percentage than the stable group(P<0.05).The eosinophil percentage and count in the TCMR group were lower than in the stable and ABMR groups(all P<0.05).Both TCMR and ABMR groups had lower basophil percentage and count,as well as lower lymphocyte percentage and count,compared with the stable group(all P<0.05).There were no significant differences in monocyte percentage and count among the 3 groups(all P>0.05).In lymphocyte subpopulations,the TCMR and ABMR groups had lower counts of CD45+cells and T cells compared with the stable group(all P<0.05).The TCMR group also had lower counts of CD4+T cells,NK cells,and B cells than the stable group(all P<0.05).There were no significant differences in the T cell percentage,CD4+T cell percentage,CD8+T cell percentage and their counts,CD4+/CD8+T cell ratio,NK cell percentage,and B cell percentage among the stable,TCMR,and ABMR groups(all P>0.05). Conclusion:The occurrence of rejection leads to impaired transplant kidney function,accompanied by characteristic changes in some parameters of routine blood tests and peripheral blood lymphocyte subpopulations in kidney transplant recipients.The different characteristics of changes in some parameters of routine blood tests and peripheral blood lymphocyte subpopulations during TCMR and ABMR may help predict and diagnose rejection and differentiate between TCMR and ABMR.

Objective:Based on bioinformatics,new immune-related LncRNAs related to the prognosis of gastric cancer were screened,and a prognostic risk model of immune-related LncRNA was further constructed,in order to be used as a new indicator for early diagnosis and prognostic status of gastric cancer.Methods:The gastric cancer transcriptome data and corresponding clinical prog-nosis data were downloaded from multiple data platforms,and the immune-related LncRNAs of gastric cancer were screened by bioin-formatics methods.Cox regression analysis was used to screen LncRNAs related to immune prognosis in gastric cancer,and LncRNAs related to immune prognosis with independent prognostic significance were identified to construct a prognostic risk model,and the risk score of each patient was calculated.Patients were divided into low-risk and high-risk groups according to the cutpoint.Kaplan-Meier analysis was performed for survival analysis and survival curves were drawn,nomograms were drawn and internal validation was per-formed,and univariate and multivariate Cox regression analysis was performed to analyze the relationship between risk scores and clin-icopathological characteristics and survival prognosis of gastric cancer patients.Results:Three immune prognosis-related LncRNAs(UCA1,MIR4435-1HG,RP11-617F23.1)were identified by Cox regression analysis,and a predictive scoring model was constructed to divide the patients into high-risk group and low-risk group according to the prognosis score.There was a statistically significant dif-ference in the prognosis of patients between the two groups(P<0.05).The multivariate Cox regression analysis risk score was an inde-pendent risk factor for the prognosis of gastric cancer,and the internal verification of the nomogram showed good reliability.Conclu-sion:Three immune-related LncRNAs in gastric cancer are significantly correlated with the prognosis of gastric cancer patients,and the predictive scoring model constructed based on them can effectively predict the prognosis and can be used as their independent prog-nostic biomarkers.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.
