Postoperative cognitive dysfunction(POCD)is the common postoperative complications in elderly patients,significantly affects their postoperative recovery and quality of life.With the intensification of population aging,how to effectively prevent and treat POCD has become an important topic in clinical re-search.Esketamine(ISLAT)serves as a new anesthetic drug and its potential in improving postoperative cog-nitive function has gradually attracted people's attention.Previous studies have shown that that esketamine can not only alleviate postoperative pain,but may also protect the neurons and reduce the incidence of POCD in elderly patients by regulating the balance of neurotransmitters and reducing inflammatory responses,and has potential clinical application value.However,the researches on the specific mechanisms of action and relat-ed signaling pathways of esketamine is still limited and requires further exploration.This article aims to inves-tigate the role of esketamine in reducing POCD in elderly patients and its related signaling pathway,clarifies the clinical usage strategy and precautions to provide a theoretical basis for clinical application.

Objective Through a non-inferiority trial design,to verify whether the efficacy of transcuta-neous electrical acupoint stimulation(TEAS)in intervening with nausea and vomiting after painless gastros-copy and colonoscopy was not inferior to that of ondansetron,and evaluate its effect on patient recovery.Meth-ods A total of 112 patients who experienced nausea and vomiting after painless gastroscopy and colonoscopy in the gastroscopy and colonoscopy center of the hospital from March 2022 to March 2023 were selected as the research subjects,and divided into the TEAS group(n=56)and the control group(n=56)according to the random number table method.The TEAS group received TEAS intervention,while the control group received ondansetron hydrochloride injection intervention.The non-inferiority margin was set at 10.0％.The interven-tion effective rate of nausea and vomiting after examination,as well as heart rate,blood pressure,length of stay,satisfaction,and visual analogue score(VAS)were compared between the two groups.Results The in-tervention effective rate of the TEAS group was close to that of the control group[82.4％(46/56)vs.80.4％(45/56)],risk difference(RD)=2.0％(95％CI:-9.8％to 13.8％),the lower limit of 95％CI(-9.8％)was higher than the preset cut-off value(-10.0％),and non-inferiority was established(P=0.032).Com-pared with before the examination,the heart rates of the two groups were slower,and the levels of systolic blood pressure(SEP)and diastolic blood pressure(DBP)were lower during the examination,and the differ-ences were statistically significant(P＜0.05).There was no statistically significant difference in the two groups of heart rate,SBP,DBP,length of stay[(69.9±14.2)min vs.(75.3±22.8)min],satisfaction score(9.8±0.6 vs.9.2±2.0),VAS(1.5±0.5 vs.2.1±0.5,P＞0.05).Conclusion The efficacy of TEAS in in-tervening with nausea and vomiting after painless gastroscopy and colonoscopy is not inferior to that of ondan-setron.

The aortic dissection is a critical emergency in cardiovascular surgery and can be classified as Stanford type A and type B aortic dissection depending on whether the ascending aorta is involved. Currently, the mainstream treatment option for type A aortic dissection is open surgery, while type B dissection can be treated by interventional therapy, open surgery, or optimal medical therapy depending on the situation. However, regardless of the treatment option, it is difficult to resolve all the problems at once. As a result, residual aortic dissection is commonly found in patients with aortic dissection. This article will review the hot issues of aortic remodeling in terms of the definition, prognosis, and risk factors.

Objective:To evaluate the long-term outcomes and prognostic factors of locally advanced gastric cancer with serosa-invasion.Methods:This study is a retrospective cohort study. The clinical and pathological data of 495 patients with locally advanced gastric cancer with serosa-invasion who underwent laparoscopic radical gastrectomy in Department of General Surgery, the First Hospital Affiliated to Army Medical University from October 2012 to October 2018 was analyzed retrospectively. There were 356 males and 139 females with an age ( M(IQR)) of 59 (16) years (range: 18 to 75 years). Observation indicators included postoperative results and long-term prognosis. The survival curve was drawn by the Kaplan-Meier method. Univariate and multivariate prognostic analysis was performed using the Cox proportional hazards model. Results:Among the 495 patients, a total of 57 patients (11.5%) were lost to follow-up, with a follow-up time of 89 (40) months (range: 23 to 134 months). The 5-year disease-free survival rate (DFS) and the 5-year overall survival rate (OS) were 56.0% and 58.2%, respectively. The 5-year DFS for patients with stage ⅡB, ⅢA, ⅢB, ⅢC were 71.2%, 60.5%, 51.6%, 33.3%, respectively. The 5-year OS for patients with stage ⅡB, ⅢA, ⅢB, ⅢC were 71.2%, 62.2%, 54.1%, 39.3%, respectively. Multivariate analysis showed that age >65 years (DFS: HR=1.402, 95% CI: 1.022 to 1.922, P=0.036; OS: HR=1.461, 95% CI: 1.057 to 2.019, P=0.022), lymph node dissection number less than 25 (DFS: HR=1.348, 95% CI: 1.019 to 1.779, P=0.036; OS: HR=1.376, 95% CI: 1.035 to 1.825, P=0.028), pathological stage Ⅲ (DFS: HR=2.131, 95% CI: 1.444 to 3.144, P<0.01; OS: HR=2.079, 95% CI: 1.406 to 3.074, P<0.01), and no postoperative chemotherapy (DFS: HR=3.127, 95% CI: 2.377 to 4.113, P<0.01; OS: HR=3.768, 95% CI: 2.828 to 5.020, P<0.01) were independent prognostic factors for the decrease in DFS and OS rates. Conclusions:Laparoscopic radical gastrectomy for locally advanced gastric cancer with serosa-invasion could achieve satisfactory long-term oncological outcomes. More lymph node dissection and standardized postoperative adjuvant chemotherapy are expected to further improve the prognosis of patients with locally advanced gastric cancer with serous invasion after laparoscopic radical surgery.

Objective To investigate the expression of neutrophil extracellular traps (NETs) and phagocytic function in the peripheral blood of patients with hepatic alveolar echinococcosis (HAE), and to examine their correlations with clinical inflamma tory indicators and liver functions. Methods A total of 50 patients with HAE admitted to Department of Hepatobiliary and Pancreatic Surgery, The Affiliated Hospital of Qinghai University from August 2022 to June 2023 were enrolled, while 50 age- and gender-matched healthy individuals from the Centre for Healthy Examinations of the hospital during the same period served as controls. The levels of NETs markers neutrophil myeloperoxidase (MPO) and neutrophil elastase (NE) were measured using enzyme-linked immunosorbent assay (ELISA). Peripheral blood neutrophils were isolated using density gradient centrifugation, stimulated in vitro using phorbol 12-myristate 13 acetate (PMA), and the levels of MPO and citrullination histone H3 (CitH3) released by neutrophils were quantified using flow cytometry. The phagocytic functions of neutrophils were examined using flow cytometry. In addition, the correlations of MPO and NE levels with clinical inflammatory indicators and liver biochemical indicators were examined using Spearman correlation analysis among HAE patients. Results The peripheral blood plasma MPO［(417.15 ± 76.08) ng/mL vs. (255.70 ± 80.84) ng/mL; t = 10.28, P < 0.05］, NE［(23.16 ± 6.75) ng/mL vs. (11.92 ± 3.17) ng/mL; t = 10.65, P < 0.05］and CitH3 levels［(33.93 ± 18.93) ng/mL vs. (19.52 ± 13.89) ng/mL; t = 4.34, P < 0.05］were all significantly higher among HAE patients than among healthy controls, and a lower phagocytosis rate of neutrophils was detected among HAE patients than among healthy controls［(70.85 ± 7.32)% vs. (94.04 ± 3.90)%; t = 20.18, P < 0.05］, and the ability to produce NETs by neutrophils was higher among HAE patients than among healthy controls following in vitro PMA stimulation. Pearson correlation analysis showed that the phagocytosis rate of neutrophils correlated negatively with platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), interleukin-6 (IL-6) level and C-reactive protein (CRP) level (r_s = −0.515 to −0.392, all P values < 0.05), and the MPO and NE levels positively correlated with inflammatory markers NLR, PLR, CRP and IL-6 (r_s = 0.333 to 0.445, all P values < 0.05) and clinical liver biochemical indicators aspartic transaminase, alanine aminotransferase, direct bilirubin and total bilirubin among HAE patients (r_s = 0.290 to 0.628, all P values < 0.001). Conclusions Excessive formation of NETs is found among HAE patients, which affects the phagocytic ability of neutrophils and results in elevated levels of inflammatory indicators. NETs markers may be promising novel biomarkers for early diagnosis, monitoring, and severity assessment of liver disease.

Objective To explore the effectiveness and safety of guiding painless gastroscopic entry with plica aryepiglottica movement as the mark.Methods A total of 200 patients with elective painless gas-troscopic examination from January 2022 to August 2022 were selected,92 males and 108 female,aged 18-60 years old,BMI 18-30 kg/m2 and ASA grade Ⅰ-Ⅲ.The patients were divided into the two groups:the con-trol group (group C) and observation group (group O) by adopting the random number table method,100 ca-ses in each group.The disappearance of eyelash reflex in the group C served as the entry timing of gastrosco-py,while the plica aryepiglottica non-movement under the gastroscopic view in the group O served as the en-try timing of gastroscopy.The bispectral index (BIS) value during gastroscopic operation persistently main-tained 40-60.The main observation indicators were the adverse reactions caused by gastroscopic operation (body movement reactions,bucking,hiccup,laryngeal spasm,etc.),and the secondary observation indicators were:general data of the two groups,SpO2,HR,SBP and DBP values after entering the room (T0),at the en-try time of gastroscopy (T1),3 min after gastroscopic entry (T2),6 min after gastroscopic entry (T3) and at the time of gastroscopic retraction (T4),and the time of medication to gastroscopy,gastroscopic operation time and intraoperative medication supplementation.Results A total of 192 cases were ultimately included,99 cases in the group C and 93 cases in the group O.There was no statistically significant difference in general da-ta between the two groups (P>0.05);compared with the group C,the use amount of cyclophosphamide dur-ing anesthesia induction in the group O was increased (P<0.05).Compared with the group C,the incidence rates of body movement reaction,bucking,hiccup and total adverse reactions in the group O were decreased (P<0.05);SpO2,HR,SBP and DBP at different time points had no statistically significant differences be-tween the two groups (P>0.05).Conclusion Using the glottic movement as the marker to guide the pain-less gastroscopy entry is effective and safe,and could reduce the adverse reactions such as body movement re-action,bucking and hiccup caused by gastroscopic entry.Observing the plica aryepiglottica movement in the gastrocopic entry operation is simple and easy to perform,which could serve an objective gastroscopic entry timing mark and is worth promoting and using in clinic.

Objective:To explore the effects of a structured exercise intervention on the healthy physical fitness in patients with leukemia receiving umbilical cord blood transplantation.Methods:It was a randomized controlled trial, conducted from August 2022 to October 2023 at the Department of Hematology of the First Affiliated Hospital of the University of Science and Technology of China (Anhui Provincial Hospital). Fifty leukemia patients undergoing umbilical cord blood transplantation were recruited and were randomly assigned to either the control group (24 cases) or the intervention group (26 cases) using a random number table method. The control group received routine nursing care, health education, and exercise guidance during hospitalization. The intervention group were given moderate-intensity structured exercise intervention, including aerobic, resistance exercises, and flexibility training, three times per week for 30 to 40 minutes per session, over a period of 6 to 8 weeks. During the study, 2 patients withdrew due to disease reasons, and finally, 22 patients in the control group and 26 patients in the intervention group were obtained. The paired t-test, Wilcoxon test, and covariance analysis were used to compare the indices of healthy physical fitness before and after the intervention between the two groups, aiming to explore the effects of a structured exercise intervention on the healthy physical fitness of leukemia patients undergoing umbilical cord blood transplantation. Results:Before the intervention, there was no significant differences in baseline characteristics, such as age, gender and disease status between the two groups (all P>0.05). During the hospitalization phase, the rate of exercise participation in the intervention group was 73.4%, the frequency of exercise was (2.20±0.41) sessions per week and the duration of each exercise session was (34.34±5.05) minutes, and the Borg′s rating of perceived exertion was (13.04±0.82) points. After intervention, the indicators including cardiovascular endurance, muscle fitness, and functional activity status in the two groups were all decreased, and the reduction degree of the indicators were all significantly lower in the intervention group when compared with those in the control group [6-minute walk distance (48.81±30.39) m vs (143.05±77.26) m, grip strength of left hand (2.57±1.30) kg vs (6.72±4.88) kg, grip strength of right hand (2.47±1.97) kg vs (6.34±5.70) kg, muscle strength of left upper limb (4.12±2.07) times vs (8.18±5.26) times, muscle strength of right upper limb (3.96±2.29) times vs (7.91±5.16) times, 30 second chair standing test (3.65±1.98) times vs (7.86±4.34) times, and timed-up-and-go test (0.65±0.53) s vs (2.35±1.79) s] (all P<0.05). The flexibility fitness was improved in the intervention group after the intervention [sit-and-reach 2.00(-4.75, 8.18) cm vs 0(-9.75, 6.43) cm] ( P=0.011), but no significant differences was found in the control group ( P>0.05). Conclusions:The structured exercise intervention has advantages in reducing the decline of healthy physical fitness in patients with leukemia receiving umbilical cord blood transplantation, and exerts a protective effect on healthy physical fitness.

[Objective]To explore the connotation of the theory of"normal Qi and blood flow forward,stagnation and rebellion will lose their consciousness"and its clinical treatment of epilepsy.[Methods]Through consulting Huangdi Neijing and later medical classics,this paper analyzed the theoretical basis of"normal Qi and blood flow forward,stagnation and rebellion will lose their consciousness",and explained the epilepsy mechanism and treatment rules and prescriptions according to this principle.[Results]The occurrence of epilepsy is related to the incompatibility of Qi and blood between the five organs and a stoppage of the circulation of tri-Jiao,while epilepsy's long course is due to the reversal of Qi and blood of each organ itself,that leads the production of stagnation.Prescriptions are based on Chaihu Jia Longgu Muli Decoction,which is added or subtracted herbs according to symptoms,while also comforting the patient that epilepsy can be treated.The attached medical record was identified as Qi blockage,pyrophlegm affecting the mind,the treatment was to clear heat from liver,eliminate phlegm for resuscitation.Modified Chaihu Jia Longgu Muli Decoction plus Ditan Decoction was used and good results were achieved.[Conclusion]This theory reveals the consciousness,Qi,blood,Yin and Yang of the human body cannot be reversed,and the truth that it flows sequentially between the organs,and that each organ runs like a headless ring.The principle of treatment is"unobstruct",which aims to smooth the"Shidao",restore the normal function of the five internal organs,treat both manifestation and root cause of disease,finally make the consciousness clear.Using modified Chaihu Jia Longgu Muli Decoction,and with words of relief,the epilepsy will be relieved.

Objective To identify meaningful objective examination methods by analyzing the results of vari-ous objective examinations of children with recurrent vertigo(RVC).Methods Fifty children with RVC(29 in ver-tigo attacking group,21 in vertigo non-attacking group)and 20 children without RVC were selected.All partici-pants underwent a series of relevant objective examinations,the results of each examination were statistically ana-lyzed and the characteristic differences of each examination between the RVC group and the control group were ob-tained.Results ① The abnormal rate of sleep SpO2,high stimulation rate ABR and AHI in the RVC group were significantly higher than those in the control group(P＜0.05).② The abnormal rate of sleep SpO2 and high stimu-lation rate ABR in the vertigo attacking group were higher than those in the vertigo non-attacking group.There was a statistical difference between the two groups(P＜0.05).③ Pure tone audiometry(or conditioned play audiome-try),acoustic immittance,cranial MRI,positional test and vHIT were normal in both RVC group and normal con-trol group.Conclusion Continuous sleep SpO2 and high stimulation rate ABR are correlated with RVC,especially RVC during vertigo attacking.AHI is correlated with RVC,but not with the onset of vertigo.Clinically,continu-ous sleep SpO2 monitoring,PSG and high stimulation rate ABR can be used as auxiliary examinations for the diagno-sis of RVC.
