ObjectiveTo explore the effect of transcutaneous electrical acupoint stimulation （TEAS） on stress response in patients undergoing unilateral biportal endoscopy （UBE） and to identify optimal TEAS parameters. MethodsA total of 96 patients undergoing UBE were randomly grouped into total intravenous anesthesia （TIVA） group， acupuncture-assisted anesthesia with continuous waves （AACW） group， and acupuncture-assisted anesthesia with sparse-dense waves （AASDW） group， with 32 patients per group. All groups were given a standardized TIVA protocol. In the AACW group （100 Hz continuous wave stimulation） and the AASDW group （2/100 Hz sparse-dense wave stimulation）， TEAS intervention was applied to both bilateral Zusanli （ST36） and Sanyinjiao （SP6） 30 minutes before TIVA induction and continued until the end of the surgery. In the TIVA group， electrodes were only connected without electrical stimulation. The stress response indicators including cortisol （Cor） and adrenocorticotropic hormone （ACTH）， heart rate （HR）， mean arterial pressure （MAP）， and bispectral index （BIS） at before anesthesia induction （T0）， after tracheal intubation （T1）， during laminectomy （T2）， and 1 hour after surgery （T3） were compared across groups. The operation duration， anesthesia duration， extubation and recovery duration were recorded， as well as pain intensity including visual analogue scale （VAS）， and sedation level （by Ramsay sedation score） at 2， 6， 12 hours after surgery， and postoperative complications. ResultsThe AACW group and AASDW group had lower ACTH and COR levels at T1， T2 and T3， as well as lower HR and MAP levels at T1 and T2 than TIVA group， with AASDW group being lower than AACW group （P＜0.05）. At T3， the AASDW group had higher BIS than TIVA group and AACW group （P＜0.05）. No significant difference in operation duration was observed （P＞0.05）. The AACW group and AASDW group had shorter anesthesia， extubation and recovery duration than TIVA group， with AASDW group being the shortest （P＜0.05）. The VAS scores at 2 h， 6 h， and 12 h after surgery in the AACW and AASDW groups were lower than those in the TIVA group， with the AASDW group showing significantly lower scores than the AACW group （P＜0.05）. The Ramsay sedation scores in the AASDW group were lower than those in the AACW group at 2 h and 6 h after surgery （P＜0.05）. The total incidence of complications in the AASDW group was 6.25% （2/32）， significantly lower than 28.13% （9/32） in the TIVA group （P＜0.05）. ConclusionTEAS can effectively suppresses stress response in patients undergoing UBE， with the 2/100 Hz sparse-dense wave parameter being most effective， which can stabilize hemodynamics， accelerate recovery， improve postoperative sedation and analgesia quality， and reduces complications.

Objective:To explore the characteristics of systemic immune microenvironment during the progression of dextran sulfate sodium(DSS)-induced acute ulcerative colitis(UC)induced in mice by Mass cytometry(CyTOF).Methods:Male C57BL/6 mice were randomly divided into control group and model group.The control group was given normal drinking water for 15 d.The mouse in the model group were given 5%DSS in drinking water,which was changed to normal drinking water after 7 days.In the model group,peripheral blood was collected on days 4,9 and 15,respectively.CyTOF was used to detect the expressions of 33 immune cell markers and changes in cell subsets in peripheral blood of mice,and the characteristics of systemic immune microenvironment in mice with acute UC were analyzed.Results:The cluster analysis of 33 kinds of immune cell markers showed that CD45+cells in peripheral blood of mice with DSS induced acute UC were divided into 23 fine subgroups,among which the proportions of B cell subgroup,T cell subgroup and neutrophil subgroup showed significant changes.A further dimensional reduction cluster analysis of T cell subsets found significant differences in the composition and proportion of the 10 identified T cell subsets.Conclusion:The systemic immune micro-environment map of mice with acute UC induced by DSS has been successfully constructed,and heterogeneity has been found in the systemic immune microenvironment of mice with acute UC.The changes and activation degree of T cell subpopulations are closely re-lated to disease progression and inflammation level.The results of this study provide theoretical basis for assisting the diagnosis,moni-toring the risk,progression,treatment and prognosis of acute UC.

Spermatogenesis is a continual process that occurs in the testes, in which diploid spermatogonial stem cells (SSCs) differentiate and generate haploid spermatozoa. This highly efficient and intricate process is orchestrated at multiple levels. N⁶-methyladenosine (m⁶A), an epigenetic modification prevalent in mRNAs, is implicated in the transcriptional regulation during spermatogenesis. However, the dynamics of m⁶A modification in non-rodent mammalian species remains unclear. Here, we systematically investigated the profile and role of m⁶A during spermatogenesis in pigs. By analyzing the transcriptomic distribution of m⁶A in spermatogonia, spermatocytes, and round spermatids, we identified a globally conserved m⁶A pattern between porcine and murine genes with spermatogenic function. We found that m⁶A was enriched in a group of genes that specifically encode the metabolic enzymes and regulators. In addition, transcriptomes in porcine male germ cells could be subjected to the m⁶A modification. Our data show that m⁶A plays the regulatory roles during spermatogenesis in pigs, which is similar to that in mice. Illustrations of this point are three genes (SETDB1, FOXO1, and FOXO3) that are crucial to the determination of the fate of SSCs. To the best of our knowledge, this study for the first time uncovers the expression profile and role of m⁶A during spermatogenesis in large animals and provides insights into the intricate transcriptional regulation underlying the lifelong male fertility in non-rodent mammalian species.

With the transition from quantity-centric healthcare to value-centric healthcare, patient-reported outcome plays an important role in healthcare. Patient-reported outcome is an effective method for evaluating the outcome of hip replacement patients. It can be used not only in science research, but also in clinical practice and medical care quality assessment. This article reviews the patient-reported outcome measures in hip replacement, so as to provide references for clinical practice and research of clinical medical and nursing staff to accurately select appropriate patient-reported outcome measures in hip replacement.

Objective:To systematically analyze and evaluate the bleeding risk prediction model of patients with venous thromboembolism (VTE) , so as to provide a reference for nursing practice.Methods:PubMed, Web of Science, Embase, Cochrane Library, Wiley Online Library, CINAHL, Scopus, ProQuest, Clinicalkey, Wanfang, China National Knowledge Infrastructure, VIP databases were searched for bleeding risk prediction model of VTE patients. The retrieval time was from the establishment of the databases to August 19, 2021. Two researchers independently screened the literature according to the inclusion and exclusion criteria, then extracted the data and evaluated the quality of the literature.Results:Ten relevant literatures were included in this study, including 4 retrospective studies and 6 prospective studies. The area under the receiver operating characteristic curve of one model was greater than 0.7, and the C-index of four models were greater than 0.7. The prediction model contained many relevant factors, including bleeding history, age, anemia, tumor, antiplatelet therapy, gender, renal insufficiency, etc. In the evaluation of risk of bias and applicability, 10 studies had good applicability, but there were bias mainly due to insufficient number of events in the dependent variable, conversion of continuous variables into dichotomous variables and missing data were not reported. Conclusions:The research on the prediction model of bleeding risk in VTE patients is still in the development stage. In the future, risk prediction models with excellent performance in all aspects and low risk of bias can be developed and verified externally.
