Objective To explore the effect of physical exercise on semen quality in order to provide basic data and theoretical basis for the improvement of male reproductive health.Methods A cross-sectional study was conducted on 1 059 males who visited the Reproductive Medicine Center of Shandong Maternal and Child Health Hospital for medical treatment and physical examination during July 2022 and April 2023.Their demographic data and physical exercise data were surveyed with questionnaires.Total sperm count,sperm concentration,total sperm motility,forward movement and normal sperm morphology were analyzed with computer aided analysis.Logistic regression model and multiple linear regression model were applied to analyze the effects of physical exercise on semen quality.Results After adjustment for confounding factors such as age,body mass index,alcohol consumption and smoking,logistic regression analysis showed that the risk of abnormal semen quality was increased in patients with moderate and heavy exercise intensity(OR=2.103,OR=2.229).Compared with the participants with physical exercise ≤10 min per session,those with＞20 min per session had a lower risk of abnormal semen quality(OR=0.357,0.256,0.289 for exercise time for＞20～30,＞30～60,＞60 min,respectively).There was no statistical significance between physical exercise frequency and semen quality(P＞0.05).The participants having exercise well were at a lower risk for abnormal semen quality(OR=0.711).Multiple linear regression analysis revealed that the frequency of physical exercise was an influencing factor of sperm concentration(β=7.474,95％CI:4.800～10.149,P＜0.05);the time of physical exercise per session was an influencing factor for total sperm count(β=20.632,95％CI:7.634～33.629);the intensity of physical exercise(β=-1.461,95％CI:-2.392～-0.530)and time of physical exercise per session(β=2.608,95％CI:1.404～3.812,P＜0.05)were influencing factors for percentage of forward motility sperm(P＜0.05);and physical exercise intensity(β=-1.934,95％CI:-3.238～-0.630),time of physical exercise per session(β=4.211,95％CI:2.525～5.897)and frequency of physical exercise(β=-2.008,95％CI:-3.480～-0.536)were influencing factors of total sperm motility(P＜0.05).Conclusion Physical exercise may affect semen quality,greater intensity of physical exercise may be a risk factor for abnormal semen quality,and longer physical exercise time may be related to improving semen quality.Therefore,proper physical exercise can help improve semen quality.

Objective:To explore the application and teaching effect of artificial intelligence (AI) image recognition education system in standardized training on ultrasound-guided nerve block technique for novice anesthesiology residents.Methods:Forty residents trained in the Department of Anesthesiology of Cancer Hospital of Chinese Academy of Medical Sciences and the Department of Anesthesiology of the Affiliated Hospital of Qingdao University from January 2023 to December 2023 were selected as study subjects, and randomly divided into experimental group (teaching with the AI image recognition education system) and control group (traditional teaching) to undergo training and assessments on the nerve block technique, with 20 residents in each group. The training quality for the two groups was assessed by comparing the clinical practice score, teaching effect evaluation, and teaching quality evaluation. SPSS 23.0 software was used for the t-test and chi-square test on data. Results:Compared with the control group, residents in the experimental group had higher clinical practice scores [(4.65±0.49) vs. (3.60±0.75), P<0.001] and better method mastery [(17.45±1.23) vs. (13.85±1.27), P<0.001], satisfaction with clinical operation [(16.70±1.34) vs. (13.95±1.00), P<0.001], and learning enthusiasm [(17.35±1.50) vs. (13.55±0.94), P<0.001] for the ultrasound-guided nerve block technique. The teaching quality score of the experimental group was higher than that of the control group [(17.30±1.59) vs. (14.25±1.68), P<0.001]. Therefore, the training quality of residents in the experimental group was better than that of the control group. Conclusions:The application of AI image recognition education system in standardized training on the ultrasound-guided nerve block technique improves the teaching quality of teachers, enhances the learning effect of novice anesthesiology residents, and mobilizes learning enthusiasm, which is worthy of further promotion and application.

Objective:To explore the changes of gait flexibility and stability in patients with Parkinson's disease (PD) 2 years after deep brain stimulation (DBS).Methods:Twenty PD patients accepted DBS in Department of Neurosurgery, Tianjin Huanhu Hospital from October 2019 to November 2021 were enrolled. Motor symptoms were evaluated by Movement Disorder Society-unified Parkinson's disease rating scale III (MDS-UPDRS-III) at preoperative medication-off state, postoperative medication-off state, and postoperative medication-on state. Mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were used to assess the cognition and 39-item Parkinson's disease questionnaire (PDQ-39) was used to evaluate the quality of life at preoperative medication-on state and postoperative medication-on state. A three-dimensional gait analyzer was used to record the gait parameters during Instrumented Stand and Walk test (ISAW) at preoperative medication-off state, postoperative medication-off state, and postoperative medication-on state. Differences in motor symptom scores, cognitive scores, quality of life scores, as well as changes in gait flexibility and stability were compared before and after DBS.Results:(1) The MDS-UPDRS-Ⅲ scores at preoperative medication-off state, postoperative medication-off state, and postoperative medication-on state ([45.30±12.57], [24.95±10.74], [15.80±7.19]) were decreased successively, with significant differences ( P<0.05).(2) Compared with those before surgery, PD patients had significantly lower levodopa equivalent daily dose (LEDD), total scores of PDQ-39, and scores of question 9 "degree of concern about falling" in PDQ-39 at 2 years after DBS ([711.84±343.99] mg/d vs. [549.30±301.08] mg/d, 47.00[30.00, 64.00] vs. 13.50[7.75, 27.00], 2.00[0.00, 3.00] vs. 0.00[0.00, 1.75], P<0.05). (3) Compared with that at preoperative medication-off state, the arm swing velocity at postoperative medication-on state statistically increased in PD patients ( P<0.05); compared with those at preoperative medication-off state, the arm swing range and turning speed at postoperative medication-off and medication-on states significantly increased in PD patients ( P<0.05); compared with that at preoperative medication-off state, the turning duration at postoperative medication-off state statistically decreased in PD patients ( P<0.05). Compared with that at preoperative medication-off state, the range of motion of the trunk in the horizontal plane at postoperative medication-off and medication-on states increased significantly in PD patients ( P<0.05); compared with that at preoperative medication-off state, the range of motion in the sagittal plane of the lumbar, coronal plane of the trunk, and sagittal plane of the trunk all increased significantly in PD patients at postoperative medication-on state ( P<0.05); the mean velocity and root mean square acceleration at postoperative medication-on state increased significantly in PD patients compared with that at preoperative medication-off state ( P<0.05); conversely, the swing frequency at postoperative medication-off state decreased significantly in PD patients compared with that at preoperative medication-off state ( P<0.05). Conclusion:Two years after DBS, PD patients exhibit obviously improved gait, with enhanced flexibility, and dynamic and static stability.

Objective:To investigate the incidence and potential risk factors associated with postopera-tive spinal epidural hematoma(SEH)following anterior cervical spine surgery(ACSS).Methods:A retrospective analysis was conducted on the clinical data of patients who underwent ACSS for cervical spondylosis at Peking University Third Hospital between March 2013 and February 2022.Patients who developed postoperative SEH were categorized as the SEH group,while those in the cohort without SEH were randomly selected as the non-SEH group by individually matching with the same operator,same gender,same surgery year,and similar age(±5 years)at a ratio of 4:1.The general condition,pre-operative comorbidities,anticoagulant or antiplatelet therapy,preoperative coagulation and platelet counts,American society of Anesthesiologists physical status classification,cervical spondylosis classifi-cation,preoperative modified Japanese Orthopaedic Society score and cervical disability index score,sur-gical modality,surgical segment levels,ossification of the posterior longitudinal ligament among the surgi-cal level,surgery duration,estimated blood loss,postoperative drainage volume,preoperative mean arte-rial pressure,mean arterial pressure during postoperative awakening periods,hospital stay and hospitali-zation cost were compared between the two groups.A bivariate Logistic regression model was applied to screen out the independent risk factors and calculate the odds ratios of indicators associated with SEH.Receiver operating characteristic curve and area under the curve(AUC)were used to describe the dis-crimination ability of the indicators.Results:A total of 85 patients were enrolled in the study,including 17 patients in the SEH group and 68 patients in the non-SEH group.Seventeen patients with SEH under-went hematoma evacuation,and all of them were successfully treated and discharged from the hospital.Corpectomy(OR=7.247;95％CI:1.962-26.766;P=0.003)and the highest mean arterial pressure during awakening(OR=1.056;95％CI:1.002-1.113;P=0.043)were independent risk factors for SEH.The AUC values were 0.713(95％CI:0.578-0.848)and 0.665(95％CI:0.51-0.82)re-spectively.The patients with SEH had longer hospital stays(P＜0.001)and greater hospitalization costs(P=0.035).Conclusion:Corpectomy and elevated maximum mean arterial pressure during awakening are independent risk factors for the development of postoperative SEH following ACSS.High-risk patients should be closely monitored during the perioperative period.

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.

Baylisascaris schroederi,a roundworm(ascaridoid)parasite specific to the bamboo-feeding giant panda(Ailuropoda melanoleuca),represents a leading cause of mortality in wild giant panda populations.Here,we present a 293-megabase chromosome-level genome assembly of B.schroederi to infer its biology,including host adaptations.Comparative genomics revealed an evolutionary trajectory accompanied by host-shift events in ascaridoid parasite lineages after host separations,suggesting their potential for transmission and rapid adaptation to new hosts.Genomic and anatomical lines of evidence,including expansion and positive selection of genes related to the cuticle and basal metabolisms,indicate that B.schroederi undergoes specific adaptations to survive in the sharp-edged bamboo-enriched gut of giant pandas by structurally increasing its cuticle thickness and efficiently utilizing host nutrients through gut parasitism.Additionally,we characterized the secretome of B.schroederi and predicted potential drug and vaccine targets for new control strategies.Overall,this genome resource provides new insights into the host adaptation of B.schroederi to the giant panda as well as the host-shift events in ascaridoid parasite lineages.Our findings on the unique biology of B.schroederi will also aid in the development of prevention and treatment measures to protect giant panda populations from roundworm parasitism.

Objective:To explore the effect of de-escalation thinking in the triage of critically ill children in the Department of Pediatrics.Methods:From January 2018 to January 2020, we selected a total of 486 critically ill pediatric patients admitted to Zhumadian Central Hospital in Henan Province. According to the random number table, the children were simply randomly divided into control group and observation group, each with 243 cases. Control group carried out traditional routine triage, and observation group conducted de-escalation thinking for pre-examination and triage. We observed the differences in the triage accuracy, satisfaction of the children and their parents and the quality of the triage between the two groups of children.Results:The scores of the disease classification and triage accuracy, total satisfaction, service attitude, treatment timeliness, health guidance as well as safety of children in observation group were higher than those in control group, and the differences were all statistically significant ( P<0.05) . Conclusions:De-escalation thinking has a high accuracy rate in the triage of critically ill children in the Department of Pediatrics, which can improve the treatment effect, reduce the adverse results of the rescue, and improve the satisfaction of the children and their family members.
