Objective:To evaluate the efficacy of intraoperative sliding CT assisted deep brain stimulation of subthalaminal nucleus (STN-DBS) in short-term motor improvement and its influencing factors in patients with Parkinson's disease (PD) under general anesthesia.Methods:The cohort consisted of 48 PD patients accepted STN-DBS in Department of Neurosurgery, First Affiliated Hospital of Zhengzhou University from June 2021 to June 2023, including 21 patients accepted STN-DBS under general anesthesia and 27 patients accepted STN-DBS under local anesthesia. STN-DBS was performed in the CT operating room and intraoperative CT was used to confirm the electrode position. Regular program-controlled follow-up for over one year in Out-patient Clinic was applied after discharge. Operation time, complications, stimulus-related adverse events, unified Parkinson's disease rating scale (UPDRS)-Ⅲ score and UPDRS-Ⅲ improvement rate at medicine-off (Med-off) stage/DBS-on stage 1 year after operation, and UPDRS-Ⅲ score and UPDRS-Ⅲ improvement rate at medicine-on (Med-on) stage/DBS-on stage 1 year after operation, and levodopa equivalent daily dose (LEDD) and LEDD reduction were compared between the two groups. Spearman rank correlation analysis or Pearson correlation analysis were used to investigate the correlation between short-term motor improvement ([UPDRS-Ⅲ score at Med-off stage before operation-UPDRS-Ⅲ score at Med-off stage/DBS-on stage 1 year after operation]/UPDRS-Ⅲ score at Med-off stage before operation×100%) and clinical data in PD after STN-DBS under general anesthesia.Results:The operation time of general anesthesia group was (1.9±0.5) h, and that of local anesthesia group was (2.6±0.8) h, with significant difference ( P<0.05). During the 1-year follow-up, no significant difference in incidence of adverse reactions, UPDRS-Ⅲ score improvement rate at Med-on and Med-off stages, LEDD and LEDD reduction was noted between the two groups ( P>0.05). In the general anesthesia group, the short-term motor improvement after STN-DBS was negatively correlated with age or gender ( P>0.05), but positively correlated with maximum improvement rate of preoperative UPDRS-Ⅲ score ( r=0.840, P<0.001). Conclusion:For patients who cannot tolerate local anesthesia, DBS under general anesthesia is also safe and effective.

Prostate cancer is the second most common malignancy among men worldwide. Owing to its unique biological characteristics (a low α/β ratio), hypofractionated radiotherapy can improve tumor control in prostate cancer. Consequently, the American National Comprehensive Cancer Network (NCCN) guidelines have recommended hypofractionated radiotherapy as the preferred treatment option for localized prostate cancer. However, the use of hypofractionated radiotherapy in pelvic irradiation after radical prostatectomy remains limited, and its safety and efficacy are yet to be fully established. Investigating the feasibility of moderate-hypofractionated post-prostatectomy radiotherapy has therefore become a recent focus of clinical research. In this review, moderate-hypofractionated post-prostatectomy radiotherapy was categorized according to the per-fraction dose and current evidence was summarized from retrospective studies, prospective studies, and ongoing clinical trials.

This article reports one case of adult COVID-19-associated acute necrotizing encephalopathy(ANEC).The patient developed disturbance of consciousness and seizure on the 12th day after SARS-CoV-2 infection.Imaging showed significant swelling and signal changes in the bilateral thalamus,brainstem,cerebral hemisphere and cerebellar hemisphere,which were consistent with the characteristic images of Acute necrotizing encephalitis(ANE).Although methylprednisolone shock therapy and high-dose human immunoglobulin therapy were given early,the patient died.ANEC often starts quickly and progresses rapidly,unconsciousness and seizure are the main manifestations.Imaging features of thalamic and subtentorial symmetry and multifocal lesions are specific for diagnosis,but the treatment and prognosis still face challenges and need further study.

Objective:To explore the role of serum cholinesterase (CHE) levels in the prognosis of patients with acute decompensated heart failure (ADHF).Methods:Total of 244 consecutive patients with ADHF who were admitted to the emergency department and were successfully discharged were prospectively enrolled from January 2018 to June 2020. Patients were divided into groups according to the first and third quartile of CHE level and the clinical data, laboratory tests and other nutritional indices were recorded after discharge, and then were followed up. The primary end points were the composites of cardiovascular death and hospitalization for worsening HF (composite end points). The secondary end points were all-cause mortality and cardiovascular death. Cox proportional risk analysis, time-dependent Cox regression model or stratified cox regression were used to identify the risk of primary and secondary endpoints. Clinical, biomarker and the compound models of clinical and biomarker were constructed. Kaplan-Meier method was used to plot the survival curves of different groups and compare their differences. Receiver Operating characteristics (ROC) curves were used to compare the area under the curve for CHE levels and other nutritional or prognostic indicators to identify composite end-point events.Results:During a follow-up period of 350(100,683) days, 158 patients reached the composite end points. In the multivariable Cox analysis, cholinesterase level was significantly associated with the composite end points after adjustment for major confounders. Cox proportional risk analysis or time-dependent Cox regression model showed that CHE level was significantly associated with the composite end points, all-cause mortality and cardiovascular mortality in both clinical, biomarker and composite models (all P< 0.05). A Kaplan–Meier analysis revealed that patients with low cholinesterase levels had significantly greater risk of reaching the composite end points than those with middle or high cholinesterase levels (78.1% vs 66.7% vs. 46.7%, P<0.001); Cholinesterase level showed the largest area under the receiver operating characteristic curve (AUROC) of 0.736 (95% CI, 0.664-0.888) for prediction of the composite end points among other nutritional indices. The AUROC of the Global Meta-Analysis Group Chronic Heart Failure (MAGGIC) Risk Score for prediction of the composite end points was increased from 0.704 to 0.762 ( P=0.038), when cholinesterase level was added. Conclusions:Cholinesterase may serve as a simple and effective prognostic marker for predicting adverse outcomes in ADHF patients.

Objective:To evaluate the clinical value of intraoperative sliding CT in deep brain stimulation (DBS) for Parkinson's disease (PD).Methods:A total of 117 PD patients accepted DBS in Department of Neurosurgery, First Affiliated Hospital of Zhengzhou University from May 2019 to May 2023 were chosen; 46 patients had local anesthesia and 71 had general anesthesia. Bilateral subthalamic nucleus (STN) DBS was performed in 73 patients, bilateral medial globus pallidus (GPi) DBS was performed in 43 patients, and right GPi and left STN DBS was performed in 1 patient. Preoperative/intraoperative sliding CT images and preoperative MRI images were fused to calculate the spatial distance between the preoperative planned target and actual target (adjusting electrode position timely in case of spatial distance greater than 2 mm [electrode displacement]). Differences of spatial distance between preoperative planned target and actual target in patients accepted different types of anesthesia and surgical modalities were compared.Results:All 117 patients were successfully operated and 234 electrodes were implanted. No patients needed a second operation for misalignment of electrodes or poor efficacy. During CT scan, neither anesthesia extubation or mechanical collision nor intracranial hemorrhage complications occurred. Spatial distance between the preoperative planned target and actual target was (1.35±0.50) mm in 117 patients. Displacement was noted in 4 electrodes and immediately adjusted during the operation; and CT re-examination confirmed good electrode position. No statistical significance in spatial distance between the preoperative planned target and actual target was noted between the general anesthesia group and local anesthesia group, and between the STN group and GPi group ( P>0.05). Conclusion:Intraoperative sliding CT is simple, safe and effective, which helps to timely adjust the electrode position during operation, avoids second operation and complications, and improves the safety and efficacy of DBS.

To evaluate the safety and efficacy of neoadjuvant radiohormonal therapy for oligometastatic prostate cancer (OMPC), we conducted a 3 + 3 dose escalation, prospective, phase I/II, single-arm clinical trial (CHiCTR1900025743), in which long-term neoadjuvant androgen deprivation was adopted 1 month before radiotherapy, comprising intensity modulated radiotherapy to the pelvis, and stereotactic body radiation therapy to all extra-pelvic bone metastases for 4-7 weeks, at 39.6, 45, 50.4, and 54 Gy. Robotic-assisted radical prostatectomy was performed after 5-14 weeks. The primary outcome was treatment-related toxicities and adverse events; secondary outcomes were radiological treatment response, positive surgical margin (pSM), postoperative prostate-specific antigen (PSA), pathological down-grading and tumor regression grade, and survival parameters. Twelve patients were recruited from March 2019 to February 2020, aging 66.2 years in average (range, 52-80). Median baseline PSA was 62.0 ng/mL. All underwent RARP successfully without open conversions. Ten patients recorded pathological tumor down-staging (83.3%), and 5 (41.7%) with cN1 recorded negative regional lymph nodes on final pathology. 66.7% (8/12) recorded tumor regression grading (TRG) -I and 25% (3/12) recorded TRG-II. Median follow-up was 16.5 months. Mean radiological progression-free survival (RPFS) was 21.3 months, with 2-year RPFS of 83.3%. In all, neoadjuvant radiohormonal therapy is well tolerated for oligometastatic prostate cancer.

Objective:To construct a bowel preparation assessment scale for patients undergoing enteroscopy based on Delphi method and provide clinical nurses with a scientific and convenient bowel preparation assessment tool.Method:The bowel preparation assessment scale for patients undergoing enteroscopy was constructed through literature review, Delphi expert correspondence and analytic hierarchy process. Using the convenient sampling method, a total of 1 988 patients who needed bowel cleansing due to enteroscopy in the Affiliated Hospital of Qingdao University from June 2020 to January 2022 were selected as the research objects. The patients who underwent enteroscopy from June 2020 to April 2021 were set up as the pre-application group ( n=980) and patients who underwent enteroscopy from April 2021 to January 2022 were set up as the post-application group ( n=1 008) . The qualified rate of bowel preparation in patients undergoing enteroscopy was compared between the two groups. Results:A total of 16 experts were invited for 2 rounds of correspondence. The effective recovery rates of the two rounds of questionnaires were respectively 100.00% and 93.75%, the expert authority coefficients were respectively 0.837 and 0.800, and the Kendall's harmony coefficients were respectively 0.207 and 0.280 (all P<0.01) . The final constructed bowel preparation assessment scale for patients undergoing enteroscopy included 4 first-level indicators, 18 second-level indicators and 47 third-level indicators. After the assessment scale was applied to the clinic, the bowel preparation qualified rate (82.24%) of patients in the post-application group was higher than that in the pre-application group (66.43%) , and the difference was statistically significant ( P<0.01) . Conclusions:The bowel preparation assessment scale for patients undergoing enteroscopy constructed based on the Delphi method is reliable, scientific and practical, which can effectively guide clinical nursing work.

Objective:This study aimed to investigate the changes of ventricular repolarization index on ECG and its relationship between prognosis in patients with acute cerebral trauma.Methods:From January 2014 to January 2018, data of 289 consecutive patients with emergency traumatic brain injuries were prospectively collected and ultimately 219 cases were selected into the study group. Meanwhile, 220 healthy persons matched by age and sex served as the control group. ECG indexes such as P wave dispersion (Pd), corrected QT(QTc), Tp-e and Tp-e/QT were all measured and calculated in the 1st and 72th hour. The independent sample t test and paired t test were used to compare the changes of the above indexes on the 1st day and the control group, the 1st day and the 3rd day, respectively, and the association between ECG indexes and the illness severity or adverse events (MACE) of the trauma group during hospitalization. Results:QTc, Tpec and Tp-e/QT of the acute cerebral trauma group increased on the 3rd day compared with the control group and on the first day, the differences were statistically significant ( P all <0.05). Tp-ec and Tp-e/QT in patients with moderate to severe brain injury in Glasgow Coma Scale (GCS) were increased, and the differences were statistically significant (150.48±16.58 vs 130.14±11.86, P=0.006). 0.29±0.04 vs 0.23±0.03, P=0.030). Tpec and Tp-e/QT were significantly increased in acute brain truma patients with MACE during hospitalization compared with those without MACE (149.76±12.52 vs 128.84±12.47, P <0.001). 0.30±0.04 vs 0.21±0.03,<0.001). Conclusion:Tp-e and Tp-e/QT in patients with acute cerebral trauma are correlated to the severity of the disease, which could be used as short-term prognostic indicators under certain conditions.
