Background: En bloc resection is recommended for the treatment of malignant and aggressive benign spinal tumors; however, it often requires a combined anterior-posterior approach, which is usually accompanied by longer surgical duration, increased blood loss, larger trauma, and surgical complexity. The present study describes a novel rotation-reversion technique for en bloc resection of the thoracic and upper lumbar spinal tumors using a posterior-only approach and evaluate its safety and efficacy. Methods: Thirteen patients with thoracic and upper lumbar (L1-L3) spinal tumors were treated with en bloc resection using the rotation-reversion technique through a posterior-only approach at our institution between 2015 and 2023. The clinical characteristics and surgical results of the patients were reviewed and analyzed. Results: Posterior-only en bloc resection was performed successfully in all 13 patients using the rotation-reversion technique, with a median follow-up of 30.4 months (range, 6–74 months). The average maximum size of these 13 tumors was 5.7 × 5.8 × 4.8 cm.The mean operation time and blood loss were 458.5 minutes (range, 220–880 minutes) and 3,146.2 mL (range, 1,000–6,000 mL), respectively, with 4 of the 13 patients (30.8%) experiencing perioperative complications. Negative margins were achieved in all the 13 patients (100%). One patient experienced local recurrence (7.7%) and 1 patient experienced instrumentation failures. Interbody fusion was confirmed in 11 of the 13 patients (84.6%), with a median fusion time of 6.9 months. All of the 13 patients experienced varying degrees of mild postoperative neurological deficits owing to resection of the nerve roots affected by tumor invasion of the vertebrae. No vessel injury or postoperative neurological paralysis occurred, except 1 patient who had been completely paralyzed before surgery. Conclusions The rotation-reversion technique is an effective procedure for en bloc resection of selected thoracic and upper lumbar spinal tumors through the posterior-only approach.

Objective:To analyze the efficacy and safety of nalbuphine for analgesia in patients with non-mechanical ventilation in intensive care unit (ICU).Methods:From December 2018 to August 2021, a multicenter randomized controlled clinical study was conducted to select non-mechanical ventilation patients with analgesic needs admitted to ICU of four hospitals in Henan Province and Guizhou Province. Patients were randomly assigned to nalbuphine group and fentanyl group. The nalbuphine group was given continuous infusion of nalbuphine [0.05~0.20 mg/(kg·h)], and the fentanyl group was given continuous infusion of fentanyl [0.5~2.0 μg/(kg·h)]. The analgesic target was critical-care pain observation tool (CPOT) score<2. The observation time was 48 hours. The primary endpoint was CPOT score, the secondary endpoints were Richmond agitation-sedation score (RASS), ICU length of stay, adverse events, and proportion of mechanical ventilation. The quantitative data of the two groups were compared by t test or Mann-Whitney U test. The enumeration data were compared by chi square test or Fisher exact probability method. The data at different time points between groups were compared by repeated measures analysis of variance. Results:A total of 210 patients were enrolled, including 105 patients in the nalbuphine group and 105 patients in the fentanyl group. There was no significant difference in baseline data between the two groups (all P>0.05). There was no significant difference in CPOT score between nalbuphine group and fentanyl group at each time point after medication ( P>0.05), the CPOT score of both groups at each time point after medication was significantly lower than that before medication, and the analgesic target could be achieved and maintained 2 hours after medication. There was no significant difference in RASS between the two groups at each time point after medication ( P>0.05), which was significantly lower than that before medication, and the target sedative effect was achieved 2 hours after medication. There was no significant difference in ICU length of stay between nalbuphine group and fentanyl group [5.0(4.0,7.5) d vs. 5.0(4.0,8.0) d, P=0.504]. The incidence of delirium, nausea and vomiting, abdominal distension, pruritus, vertigo and other adverse events in the nalbuphine group was lower than that in the fentanyl group (all P<0.05). There was no significant difference in the incidence of other adverse events such as deep sedation, hypotension and bradycardia between the two groups (all P>0.05). The incidence of respiratory depression in nalbuphine group was not significantly different from that in fentanyl group ( P>0.05), but the proportion of mechanical ventilation was significantly lower than that in the fentanyl group [1.9% (2/105) vs. 8.6%(9/105), P=0.030]. Conclusions:Nalbuphine could be used for analgesia in ICU patients with non-mechanical ventilation. The target analgesic effect could be achieved within 2 hours, and it had a certain sedative effect with a low incidence of adverse reactions.

Objective:To investigate the alterations of brain resting-state functional connectivity in patients with leukoaraiosis(LA), and to explore its neuropathological mechanism of cognitive dysfunction.Methods:From August 2022 to February 2023, 28 patients with LA(LA group) and 30 gender, age and education level matched normal controls(NC group) in Jiangsu Shengze Hospital affiliated to Nanjing Medical University were prospectively recruited.Mini mental state examination, trail-making test, and Stroop color-word test were used to evaluate the cognitive function of participants, rs-fMRI images were processed by DPABI V6.1 based on MATLAB R2022a.Voxel-mirrored homotopic connectivity(VMHC) values were calculated and two-sample t test were performed to compare the differences in local brain activity between the two groups.The brain regions with significant differences were selected as the seeds to calculate the functional connectivity(FC) values of the whole brain, and Pearson correlation analyses were performed to evaluate the correlation between the FC values and neuropsychological scores. Results:The VMHC values of the calcarine fissure and surrounding cortex(CAL) (x=±18, y=-63, z=15), postcentral gyrus(PoCG) (x=±39, y=-27, z=48), lingual gyrus(LING) (x=±12, y=-51, z=-6), middle occipital gyrus(x=±27, y=-75, z=24) and insula(x=±36, y=6, z=3) in the LA group were lower than those in the NC group( P<0.05). The seed points FC results showed, FC values between right CAL(CAL.R) and bilateral precuneus(PCUN), right dorsolateral prefrontal cortex(DLPFC.R) and right temporal_mid were reduced in the LA group( P<0.05); FC values between PoCG.R and left CAL, left temporal_mid and right LING were reduced too( P<0.05). Additionally, the FC value in the LA group between CAL.R and DLPFC.R was negatively correlated with the Stroop C score( r=-0.39, P<0.05). The FC value in LA group and NC group between CAL.R and DLPFC.R was negatively correlated with the Stroop C score( r=-0.48, P<0.001)and also negatively correlated with the trail making test B(TMT-B) score( r=-0.40, P<0.01), and the FC value between CAL.R and PCUN.L was negatively correlated with the TMT-B score( r=-0.45, P<0.001). Conclusion:Desynchronized interhemispheric functional connectivity and abnormal cortical circuit functional connectivity were probably associated with the underlying neural mechanisms of cognitive impairment in LA.

Objective:To compare the effects of thoracoscopic anatomical segmentectomy and thoracoscopic lobectomy on patients' respiratory function.Methods:Retrospective analysis of 326 patients who underwent thoracoscopic surgery from July 2016 to July 2019(209 patients underwent anatomical segmentectomy, 117 patients underwent lobectomy). According to variables including gender, age, tumor location, smoking history and BMI, two propensity score-matched cohorts including 89 patients respectively were constructed. The patients’ baseline data and respiratory function date of the patients pre-operation and post-operation were analyzed. The measurement data that obey the normal distribution were described by mean±standard deviation, and the t-test was used for comparison between groups; the measurement data of non-normal distribution was described by the median value( P25, P75), and the Wilcoxon rank sum test was used for the comparison between groups; The data was described by frequency, and the chi-square test or Fisher's exact probability method was used for comparison between groups. Results:At the first-month follow-up after surgery, there was no significant difference in the variation of FVC[(0.48±0.40)L vs.(0.34±0.37)L, P=0.215)and FEV1[(0.52±0.46)L vs.(0.43±0.77)L, P=0.364), and in the change rate of FVC(%)[15.23(8.74, 21.25) vs. 14.58(7.75, 19.40), P=0.122], FEV1(%)[17.25(9.56, 22.78) vs. 16.42(9.15, 20.28), P=0.154]and DLCO(%)[18.54(10.88, 25.68)vs. 17.45(9.58, 23.75) P=0.245]. Between the segmentectomy group and lobectomy group, there was a significant difference in the alteration of FVC[(0.50±0.47)L vs. (0.29±0.31)L, P=0.031] and FEV1[(0.44±0.34)L vs.(0.24±0.23)L, P<0.001], the change rate of FVC(%)[14.27(7.87, 22.32) vs. 9.95(5.56, 17.24), P=0.008]、FEV1(%)[15.23(8.36, 22.17)vs. 10.05(5.15, 18.54), P<0.001]and DLCO(%)[13.74(6.24, 19.78) vs. 4.45(-2.32, 13.75), P=0.023]in the 6th month after surgery. The lobectomy group had a higher variation of FEV1[(0.34±0.49)L vs.(0.18±0.26)L, P=0.006] and change rate of FVC(%)[9.28(2.15, 18.94) vs. 5.24(0.52, 11.45), P=0.0032] and FEV1(%)[10.45(3.15, 21.32) vs. 6.50(1.55, 14.24), P<0.001] in the first year after surgery. However, the variation of FVC[(0.29±0.36)L vs.(0.21±0.24)L, P=0.176) and the change rate of DLCO(%)[8.35(2.15, 16.45) vs. 6.23(2.12, 14.54), P=0.143] didn't show a significant difference between the two groups. Conclusion:Whether in the short or the middle postoperative period, segmentectomy can preserve postoperative respiratory function than lobectomy.

Objective:To determine the spiritual needs of shrinking man syndrome (SMS) in young and middle-aged patients, and to provide reference for determining targeted intervention plans.Methods:From May to July, 2021, 14 young and middle-aged patients with SMS who received hyperparathyroidism thermal ablation in the Interventional Medicine Department of China-Japan Friendship Hospital were selected by purpose sampling method. Qualitative research phenomenology was used to conduct semi-structured in-depth interviews, and the interview data were analyzed by Colaizzi 7-step analysis method.Results:There were 4 themes and 14 sub-themes: "understanding and self-acceptance of illness" (attribution to illness; disease uncertainty; acceptance and illness), "need for social support" (love and respect; connection and companionship; family support; medical support; patient support), "life value and sense of meaning" (life meaning and goal; self-esteem; religious belief), "self-actualization and transcendence" (hope for improvement; eager for miracles; realize your value).Conclusions:Medical staff should pay attention to the spiritual needs of young and middle-aged patients with SMS, and specifically meet their spiritual needs during diagnosis, treatment, nursing and follow-up, so as to improve the patients′ sense of life meaning and value, and help them to better survive with disease and return to society.

Early distinction of bipolar disorder (BD) from major depressive disorder (MDD) is difficult since no tools are available to estimate the risk of BD. In this study, we aimed to develop and validate a model of oxidative stress injury for predicting BD. Data were collected from 1252 BD and 1359 MDD patients, including 64 MDD patients identified as converting to BD from 2009 through 2018. 30 variables from a randomly-selected subsample of 1827 (70%) patients were used to develop the model, including age, sex, oxidative stress markers (uric acid, bilirubin, albumin, and prealbumin), sex hormones, cytokines, thyroid and liver function, and glycolipid metabolism. Univariate analyses and the Least Absolute Shrinkage and Selection Operator were applied for data dimension reduction and variable selection. Multivariable logistic regression was used to construct a model for predicting bipolar disorder by oxidative stress biomarkers (BIOS) on a nomogram. Internal validation was assessed in the remaining 784 patients (30%), and independent external validation was done with data from 3797 matched patients from five other hospitals in China. 10 predictors, mainly oxidative stress markers, were shown on the nomogram. The BIOS model showed good discrimination in the training sample, with an AUC of 75.1% (95% CI: 72.9%-77.3%), sensitivity of 0.66, and specificity of 0.73. The discrimination was good both in internal validation (AUC 72.1%, 68.6%-75.6%) and external validation (AUC 65.7%, 63.9%-67.5%). In this study, we developed a nomogram centered on oxidative stress injury, which could help in the individualized prediction of BD. For better real-world practice, a set of measurements, especially on oxidative stress markers, should be emphasized using big data in psychiatry.

Objective:To investigate the mediating effect of hope on resilience and post traumatic growth (PTG) in patients with refractory secondary hyperparathyroidism (rSHPT).Methods:It was convenient to select rSHPT patients and non-refractory SHPT patients who received maintenance hemodialysis treatment in China-Japan Friendship Hospital from September 2018 to September 2021. Totally 495 patients with rSHPT and 1 295 patients with mild secondary hyperparathyroidism (SHPT) were surveyed by the Chinese Version of The Herth Hope Scale, the Chinese version of the Connor-Davidson Resilience Scale and the Post Traumatic Growth Rating Scale (PTGI). After matching according to the 1∶1 Propensity Score Matching (PSM), 436 cases were set in each of the two groups. The differences of hope, resilience and PTG scores between the two groups were compared. Pearson correlation analysis was used to analyze the correlation between hope, resilience and total score of PTG in rSHPT group. Regression analysis and SPSS Process mediation Model 4 were used to test the mediating effect of hope on resilience and PTG.Results:The hope score (32.16 ± 4.15), psychological resilience score (61.22 ± 14.38), and the PTG score (52.34 ± 18.92) of rSHPT patients was significantly lower than 33.41 ± 2.97 ( t=-5.72, P<0.05), 63.19 ± 7.25 ( t=-2.77, P<0.05), 57.95 ± 10.07 ( t=-6.34, P<0.05) of SHPT patients. There was a positive correlation between hope, resilience and PTG score ( r=0.671, 0.488, 0.523, all P<0.01). Regression analysis showed that resilience could positively predict PTG ( β=0.518, P<0.01). Psychological resilience positively predicted hope ( β=0.188, P<0.01). Resilience ( β=0.204, P =0.002) and hope ( β=1.442, P<0.01) could positively predict PTG. Hope played a partial mediating role in the relationship between resilience and PTG, and the mediating effect accounted for 60.23%. Conclusions:rSHPT patients generally had lower levels of hope, resilience and PTG. Resilience can affect PTG directly or indirectly through hope. Medical staff should improve the resilience and hope level of patients with rSHPT through positive psychological intervention measures, so as to enhance the positive promoting effect of psychological resilience on PTG.
