Objective Observational studies have shown an association between Parkinson disease （PD） and mental illness， but further studies are needed to explore the causal relationship between them. This study aims to investigate such causal relationship using the method of two-sample Mendelian randomization （MR）. Methods Related data were extracted from GWAS， and summary statistics associated with PD， depression， sleep disorders， and anxiety phenotype-variants were obtained. Single nucleotide polymorphisms （SNPs） for PD were selected as instrumental variables， and MR-PRESSO was used to exclude outliers. Inverse variance weighting was used as the main method to assess causal effect estimates， and MR Egger， weighted median， simple mode， and weighted mode were used to verify the robustness of the findings. A sensitivity analysis was used to validate the reliability of the results， including the Cochran Q test， the MR-Egger intercept test， funnel plots， and the leave-one-out method. Results A total of 21 SNPs associated with PD were identified. The MR analysis showed that PD had a causal relationship with depression （OR=0.974，95%CI 0.934‒1.015， P=0.210）， sleep disorders （OR=1.056， 95%CI 0.970-1.149， P=0.211）， and anxiety （OR=0.998， 95%CI 0.996‒1.001， P=0.118）， with no statistical significance. Different MR analyses and sensitivity analyses showed that PD did not directly contribute to the development of mental illness. Conclusion There is no direct causal relationship between PD and depression/sleep disorders/anxiety. In clinical practice， healthcare professionals should pay attention to the mental health of patients with PD. Randomized controlled studies should be conducted in the future to further validate the results of this study.

Objective To investigate the effect of tetrandrine tablets on inflammatory cytokines and acute phase response following the first-dose of zoledronic acid in postmenopausal osteoporosis patients. Methods 80 postmenopausal osteoporosis patients receiving the first-dose of zoledronic acid admitted in the Affliated Xuzhou Municipal Hospital of Xuzhou Medical University from June, 2022 to December, 2024 were selected as study objects, and the patients were randomly divided into control group （40 cases, prophylactic treatment with acetaminophen tablets） and study group （40 cases, prophylactic treatment with tetrandrine tablets and acetaminophen tablets）. The high-sensitivity C-reactive protein （hs-CRP）, interleukin-1β （IL-1β）, IL-6, tumor necrosis factor-α （TNF-α） and the occurrence of acute phase reactions （fever, muscle and joint pain, gastrointestinal discomfort） between two groups were compared. Results The levels of serum hs-CRP, IL-1β, IL-6, and TNF-α in both groups significantly increased on day 1 and day 3 after infusion of zoledronic acid （all P values <0.05）. The levels of serum hs-CRP, IL-6, and TNF-α in the control group were higher than those in the study group on day 1 and 3 after infusion of zoledronic acid, with statistical significance （all P values <0.05）. In terms of acute phase reactions, the incidence of fever, muscle and joint pain in the control group after infusion of zoledronic acid were higher than those in the study group, with statistical significance （P<0.05）. No statistically significant difference in the incidence of gastrointestinal discomfort between the two groups （P>0.05）. Conclusion Tetrandrine tablets could reduce the expression levels of hs-CRP, IL-1β, IL-6, and TNF-α following the first-dose of zoledronic acid in postmenopausal osteoporosis patients, reduce the incidence of acute phase reactions, and alleviate adverse reactions.

China now has the largest number of people living with diabetes worldwide. To address such a burden, the Healthy China 2030 initiative and subsequent Healthy China Initiative-Diabetes Prevention and Treatment Action Plan(2024-2030)were launched. A shift from " disease-centred" approach to " health-centred" approach and from treatment to prevention is the core of diabetes management in China. Various regions have formed some characteristic prevention and control models with local features in their long-term diabetes prevention and control work, such as the " Community Three-in-One" management model, hospital-community integrated prevention and control model, " Three Doctors Shared Management" model, and family doctor model. Based on the description of the current situation of diabetes prevention and control in China, this article elaborates on the diabetes prevention and control model, key measures, and practical effects in Bao′an District, Shenzhen. It aims to introduce the practices and reflections on diabetes prevention and control in Bao′an, Shenzhen, and provide experiential reference for diabetes prevention and control in other areas.

Objective To analyze the clinical characteristics,laboratory test,imaging examination,and treatment outcome of invasive Klebsiella pneumoniae liver abscess syndrome(IKPLAS)in the elderly,and improve clinicians' understanding on this disease.Methods Clinical data of 7 elderly patients who were diagnosed with IKPLAS in a hospital from January 2020 to February 2024 were analyzed retrospectively.Results Among the 7 elderly patients with IKPLAS,there were 3 males and 4 females,ranging in age from 60 to 78 years old.All 7 patients were with community-acquired infection.The main clinical symptoms were fever(n=7),chills(n=6),upper abdominal pain(n=4),fatigue and poor appetite(n=3),cough and expectoration(n=5),vomiting(n=3),vision decrease(n=2),and disturbance of consciousness(n=1).All 7 patients had pathogenic evidence of Klebsiella pneumoniae(KP),including 4 cases with KP isolated from liver puncture pus,3 from blood culture,and 1 from both liver puncture pus and intraocular pus.Among the 7 patients,there were 5,2,1,3,1,1 cases combined with pulmonary abscess,endophthalmitis,brain abscess,bloodstream infection,urinary system infection,and pelvic infection,re-spectively.Conclusion Elderly patients with IKPLAS have a variety of underlying diseases and diverse clinical symptoms,showing no specificity.Once IKPLAS was suspected,timely testing for pathogen and screening for other metastatic infection sites outside the liver should be performed.Timely drainage of liver abscess and selection of ap-propriate antimicrobial agents for treatment based on antimicrobial susceptibility testing result can improve patients' survival rate.

Objective To investigate the clinical effect of hemorrhoidal artery ligation combined with ultrasonic knife resection,suture,ligature and suspension in the treatment of mixed hemorrhoids with annular prolapse.Methods A retrospective analysis was conducted to select 80 patients with annular prolapse mixed hemorrhoids admitted to the anorectal Department of our hospital from January 2022 to April 2023.According to different treatment plans,they were divided into control group(n=40 cases)who received external stripping and internal ligation combined with tape ligation,and study group(n=40 cases)who received hemorrhoidal artery ligation combined with ultrasonic knife resection,suture,ligation and suspension.The operative effect,operative status,postoperative anal pain,anal edema,stool blood score and quality of life were evaluated.Results The effective rate of the study group was 97.50％,which was higher than that of the control group(77.50％)(P＜0.05).The operation time,intraoperative blood loss,hospital stay and wound healing time of the research group were(25.03±10.00)minutes,(10.00±5.32)ml,(7.25±1.54)days and(12.21±2.00)days respectively.[is better than that of control group(29.85±14.00)minutes,ml(17.85±10.25),(11.87±2.35),(18.89±4.85)days],two groups of comparison,the difference was statistically significant(P＜0.05).The VAS scores of anal pain in the study group on 1 day,3 days and 7 days after the operation were(4.25±0.85)points,(2.89±0.54)points and(2.00±0.30)points,respectively.The scores of perianal edema were(1.87±0.36)points,(1.41±0.30)points,and(1.00±0.20)points,respectively.The hematochezia scores were(1.85±0.21)points,(1.34±0.18)points,and(0.85±0.13)points,respectively.Which were better than that of control group[(7.56±1.10),(6.54±1.03),(4.87±1.00)][(2.40±0.58),(2.03±0.49),(1.87±0.45)][(2.45±0.55),(2.03±0.47),(1.88±0.25)],and the differences were statistically significant(P＜0.05).The recurrence rate was 2.50％in the study group and 17.50％in the control group(P＜0.05).The scores of SF,MH,PF and GH of the Modified Health Survey Summary Form(SF-36)in the study group were(88.54±10.22,87.87±10.58,88.97±10.00,89.95±10.05)higher than those of the control group(67.52±10.00,70.10±11.25,71.10±9.85,70.00±10.00)(P＜0.05).Conclusion Hemorrhoidal artery ligation combined with ultrasonic knife resection,suture,ligature and suspension in the treatment of patients with annular prolapse mixed hemorrhoids has ideal surgical effect and little trauma,which is beneficial to promoting postoperative rehabilitation,alleviating anal pain,improving anal edema and hematostoecium,and improving quality of life.

Objective To explore the prognostic value of serum glutathione reductase(GR),superoxide dismutase(SOD),cystatin C(Cys-C),homocysteine(Hcy)and lipoprotein a[Lp(a)]levels in patients with cerebral ischemic stroke(CIS),and to provide a reference for improving the prognosis of CIS patients.Methods 126 patients with CIS admitted to the 980th Hospital of Joint Logistics Support Force from June 2022 to April 2023 were selected as the observation group,another 126 healthy individuals were selected as the control group at a ratio of 1:1.The expression levels of GR,SOD,Cys-C,Hcy and Lp(a)in the two groups were detected and compared after admission and during physical examination.The degree of neurological deficit in patients with CIS was classified into mild(NIHSS:2～4 points,n=35),moderate(NIHSS:5～15 points,n=47),moderate-severe(NIHSS:16～20 points,n=26)and severe(NIHSS:21～42 points,n=18)according to the National Institutes of Health Stroke Scale(NIHSS).The expression of serum GR,SOD,Cys-C,Hcy and Lp(a)in patients with different degrees of neurological deficit was compared,and the correlation between each indicator and the degree of neurological deficit was analyzed.The observation group received intravenous thrombolytic therapy after admission and was re-examined one day after thrombolysis.After treatment,follow-up visits were conducted for 28 days.According to the patient's condition(modified Rankin scale),patients were divided into good prognosis(n=94)and poor prognosis groups(n=32).The levels of each indicator in patients with different prognoses were compared,and the predictive value of GR,SOD,Cys-C,Hcy and Lp(a)expression for poor prognosis and early warning were analyzed.Results The expression levels of serum GR(48.54±3.07U/L)and SOD(157.17±25.47U/ml)in the observation group were lower than those in the control group(61.68±3.15U/L,203.63±18.31U/ml),while the expression levels of Cys-C(1.24±0.28mg/L),Hcy(15.21±1.62μmol/L)and Lp(a)(386.53±52.16mg/L)were higher than those in the control group(0.82±0.23mg/L,9.58±0.60μmol/L,257.83±45.34mg/L),with statistically significant differences(t=13.011～36.582,all P<0.05).As the disease progressed,the expression levels of GR and SOD gradually decreased,while the expression levels of Cys-C,Hcy and Lp(a)gradually increased,with statistically significant differences(F=14.685～197.041,all P<0.05).Spearman analysis,GR and SOD were negatively correlated with the degree of neurological deficit in patients with CIS(r=-0.814,-0.753,all P<0.05),while Cys-C,Hcy and Lp(a)were positively correlated with the degree of neurological deficit in patients with CIS(r=0.647,0.782,0.724,all P<0.05).The expression of GR and SOD in patients with good prognosis at admission and 1 day after thrombolysis was higher than that in patients with poor prognosis(t=9.109,6.338;2.934,4.358,all P<0.05),while the expression of Cys-C,Hcy and Lp(a)was lower than that in patients with poor prognosis(t=5.246,5.118,8.561;4.636,5.298,7.461,all P<0.05).The AUC(95%CI)of combined prediction of GR,SOD,Cys-C,Hcy and Lp(a)at admission was 0.898(0.832～0.945),and the AUC(95%CI)of combined prediction of GR,SOD,Cys-C,Hcy and Lp(a)at 1 day after thrombolysis was 0.931(0.871～0.968).The RR(95%CI)values caused by the expression of GR,SOD,Cys-C,Hcy and Lp(a)at 1 day after thrombolysis were 2.868(1.594～5.161),3.194(1.807～5.645),0.155(0.082～0.291),0.150(0.071～0.319)and 0.227(0.119～0.435).Conclusion Abnormal changes in the levels of GR,SOD,Cys-C,Hcy and Lp(a)are closely related to the degree of neurological deficit and prognosis in patients with CIS.Early combined detection of GR,SOD,Cys-C,Hcy and Lp(a)levels has high predictive value and early warning for evaluating the poor prognosis of patients with CIS.

Objectives:To analyze the clinical characteristics of upper cervical vertebrae with dumbbell schwannoma,and to explore its clinical symptoms,imaging features,and treatment plans.Methods:A retro-spective analysis was performed on 14 patients with upper cervical intra-and extraspinal dumbbell-shaped schwannoma admitted to the Spinal Surgery Department of Southern Theater General Hospital from January 2022 to June 2024,including 9 males and 5 females,aged 43.64±11.96 years(25-61 years).According to the location,size,scope of the tumor,and relationship with the surrounding important tissue structure in upper cervical spine,the relevant clinical treatment data were analyzed and the surgical treatment plan was dis-cussed.Cervical X-ray,CT and MRI examinations were regularly performed after surgery to evaluate the con-ditions of complete resection of tumor and recurrence,the stability of the upper cervical spine and whether the internal fixation was loose or broken.The recovery of spinal nerve function and pain improvement were evaluated by the Japanese Orthopaedic Association(JOA)and visual analogue scale(VAS)scores.Results:All the patients underwent complete tumor resection in one stage,and the postoperative JOA score(10.14±1.55 vs 13.86±1.06,P=0.005)and VAS score(2.42±1.29 vs 0.64±0.71,P=0.000)were statistically different from those before surgery.Postoperative tumor histopathology was confirmed as schwannoma in all the 14 patients.The follow-up time was 6 months to 2 years.No recurrence of tumor was found,neurological symptoms were significantly improved,and no upper cervical instability appeared.Conclusions:For patients with intra-and extra-spinal dumbbell-shaped schwannoma in the upper cervical spine,complete resection of the tumor in one stage of posterior approach can be given priority.If the important stable tissue structure of the upper cervical spine is destroyed,upper cervical spine fixation and fusion should be performed to ensure the stabil-ity of upper cervical spine after tumor resection.

Objective:To explore the learning patterns of resident physicians in anesthesiology when performing tracheal intubation guided by Shikani laryngoscope, and provide a reference for the skill training of clinical anesthesiologists.Methods:From August 2023 to December 2024, a total of 19 resident physicians specializing in anesthesiology participated in this study at Peking University Third Hospital. All resident physicians received standardized training on clinical skills. None of them had received specialized training in Shikani laryngoscope-guided tracheal intubation. The relevant theoretical teaching and practical guidance were provided by the same senior attending physician throughout the study. A flipped-classroom teaching model was adopted, and each student was instructed by the teaching physician to perform the procedure on 15 cases in chronological order, resulting in a total of 285 cases. The cumulative sum (CUSUM) value for each tracheal intubation was calculated, and the learning curve was plotted using R software. A fourth-order polynomial nonlinear regression model was used to fit the curve and estimate the 95% confidence interval of the learning curve. The first-order derivative function of the regression model was further analyzed to reveal the dynamic changes in proficiency with the number of training sessions. The CUSUM curve was segmented using the maximum statistics test to identify the optimal breakpoint.Results:The maximum selection test revealed that the breakpoint for the increase in CUSUM level was at the eighth attempt.Conclusions:Resident physicians in anesthesiology can master Shikani laryngoscope-guided tracheal intubation after eight standardized training sessions. Moreover, the participants showed high satisfaction with the flipped-classroom teaching model.
