Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To analyze the clinical adverse events of the first carbon ion therapy system in radiotherapy for cancer patients in China.Methods:A retrospective analysis was conducted on the clinical trial monitoring data of the carbon ion therapy system obtained by the Pharmacovigilance Center of Gansu Province. A descriptive study was conducted on the demographic characteristics, radiotherapy techniques, irradiation site and dose parameters, postoperative follow-up, and adverse event information of 46 tumor patients who received carbon ion therapy and participated in the clinical trial in Wuwei Cancer Hospital, Gansu Province from November 2018 to February 2019. Frequency and percentage were used to describe and analyze the occurrence of adverse events after carbon ion therapy for cancer patients in different groups. All subjects who received radiotherapy were grouped according to the treatment dose and fractionation method.Results:The median age of the 46 patients was 47 years old, and the male to female ratio was 30∶16. There were 15, 5, 8, 9, and 9 patients with head and neck, chest, abdomen, pelvic cavity, and limb spinal tumors, respectively. The total duration of radiotherapy was 2-4 weeks for 10-16 times. There were 246 adverse events in 45 cases, with an incidence of 98%. No severe adverse events occurred. The adverse events definitely related to carbon ion devices accounted for 19.1%, and no severe adverse events related to carbon ion devices occurred. According to the evaluation criteria of common terminology criteria for adverse events (CTCAE), the main adverse events were CTCAE grade 2 and below, with only 1 (2%) head and neck tumor patient (nasopharyngeal malignant tumor) experienced CTCAE grade 3 adverse events after treatment. In addition, 43 patients developed acute adverse reactions, with an incidence of 93%, mainly involving the skin, mucosa, eyes, ears, pharynx and esophagus, upper gastrointestinal tract, lower gastrointestinal tract (including pelvic cavity), lung, genitourinary tract, heart, central nervous system and hematology (white blood cells, platelets and neutrophils), etc. Conclusion:The adverse reactions of patients treated with the first carbon ion therapy system are mainly CTCAE grade 2 and below, and the clinical adverse events are mild and controllable.

Background::Whether anesthetic depth affects postoperative outcomes remains controversial. This meta-analysis aimed to evaluate the effects of deep vs. light anesthesia on postoperative pain, cognitive function, recovery from anesthesia, complications, and mortality. Methods::PubMed, EMBASE, and Cochrane CENTRAL databases were searched until January 2022 for randomized controlled trials comparing deep and light anesthesia in adult surgical patients. The co-primary outcomes were postoperative pain and delirium (assessed using the confusion assessment method). We conducted a meta-analysis using a random-effects model. We assessed publication bias using the Begg’s rank correlation test and Egger’s linear regression. We evaluated the evidence using the trial sequential analysis and Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. We conducted subgroup analyses for pain scores at different postoperative time points and delirium according to cardiac or non-cardiac surgery.Results::A total of 26 trials with 10,743 patients were included. Deep anesthesia compared with light anesthesia (a mean difference in bispectral index of -12 to -11) was associated with lower pain scores at rest at 0 to 1 h postoperatively (weighted mean difference = -0.72, 95% confidence interval [CI] = -1.25 to -0.18, P= 0.009; moderate-quality evidence) and an increased incidence of postoperative delirium (24.95% vs. 15.92%; risk ratio = 1.57, 95% CI = 1.28-1.91, P < 0.0001; high-quality evidence). No publication bias was detected. For the exploratory secondary outcomes, deep anesthesia was associated with prolonged postoperative recovery, without affecting neurocognitive outcomes, major complications, or mortality. In the subgroup analyses, the deep anesthesia group had lower pain scores at rest and on movement during 24 h postoperatively, without statistically significant subgroup differences, and deep anesthesia was associated with an increased incidence of delirium after non-cardiac and cardiac surgeries, without statistically significant subgroup differences. Conclusions::Deep anesthesia reduced early postoperative pain but increased postoperative delirium. The current evidence does not support the use of deep anesthesia in clinical practice.

At present, heavy ion is an ideal radiation for cancer treatment, and carbon ion is used in the treatment of many kinds of cancer due to its higher relative biological effect value. In 2019, Wuwei heavy ion center built the first medical heavy ion accelerator-carbon ion radiotherapy system in China, and obtained the registration license from the National Medical Products Administration, and officially received cancer patients in March 2020. This study introduced the development and application of the first carbon ion radiotherapy system in China.

Objective:To observe the clinical characteristics and guideline compliance of chronic obstructive pulmonary disease (COPD) patients with initial triple therapy in real-life world.Methods:This study is a cross-sectional study. The subjects of the study were COPD patients admitted to 13 hospitals in Hunan Province and Guangxi Zhuang Autonomous Region from December 2016 to December 2021. The initial treatment was triple inhaled drugs. The data collected included gender, age, diagnosis, body mass index (BMI), history of acute exacerbation (AE) in the past year, pulmonary function, COPD Assessment Test (CAT) score, modified British Medical Research Council Dyspnea Questionnaire (mMRC), inhaled drugs and other indicators. The characteristics and differences of COPD patients before and after 2020 were analyzed.Results:7 184 patients with COPD were enrolled in this study, including 2 409 COPD patients treated with initial triple therapy, accounting for 33.5%(2 409/7 184). Taking January 1st, 2020 as the cut-off point, 1 825 COPD patients (75.8%) received initial treatment with triple inhaled drugs before 2020 and 584 patients (24.2%) after 2020 were included in this study. Compared with COPD patients before 2020, the COPD patients after 2020 had higher FEV 1% [(40.9±15.5 )% vs (39.3±15.5)%, P=0.040], lower CAT [(15.8±6.5)point vs (17.5±6.2)point, P<0.001], less AE in the past year [1(0, 2)times vs 1(0, 2)times, P=0.001] and higher rate of non-AE [255(43.7%) vs 581(37.1%), P=0.006]. In addition, before 2020, patients with COPD were mainly treated with open triple drugs (1 825/1 825, 100%); after 2020, 306 patients (52.4%) received open triple inhaled drugs, and 278 patients (47.6%) received closed triple inhaled drugs. Conclusions:In real-life world, most of patients with COPD treated with triple therapy have severe lung function, obvious symptoms and high risk of acute exacerbation. The real-world prescribing of triple therapy in patients with COPD does not always reflect recommendations in guidelines and strategies, and overtreatment is common. After 2020, prescribing triple therapy for COPD patients is more positive and worse consistency with guideline.

Objective:To evaluate the clinical efficacy of Sini-Jia-Huanglian Decoction on chronic heart failure (CHF) with qi deficiency and blood stasis syndrome. Methods:A total of 100 patients with CHF and qi deficiency and blood stasis syndrome in Handan Mingren hospital from January 2018 to June 2019 who met the inclusion criteria were divided into two groups according to the random number table method, 50 cases in each group. The control group was treated with conventional western medicine therapy, and the treatment group was treated with Sini-Jia-Huanglian Decoction on the basis of the control group. Both groups were treated for 30 days. TCM syndrome score was performed before and after treatment. The level of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) was detected by radioimmunoassay. The levels of peptide and galectin 3 (Gal-3) were detected by ELISA. The exercise tolerance was measured by 6-minute walking test, the clinical efficacy was tevaluated. Results:The total effective rate of the treatment group was 92.0% (46/50), and the control group was 76.0% (38/50), there was significant difference between the two groups ( χ2=4.762, P=0.029). After treatment, the scores of shortness of breath, palpitation, dyspnea, dizziness, chest pain and total scores in the treatment group were significantly lower than those in the control group ( t values were 4.257, 8.493, 8.211, 4.481, 5.500, 6.977, respectively, all Ps<0.01). After treatment, the levels of NT-proBNP (2 349.61 ± 683.50 ng/L vs. 3 026.27 ± 714.35 ng/L, t=4.840), and peptide (12.16 ± 3.43 ng/L vs. 17.52 ± 3.98 ng/L, t=7.214) and Gal-3 (3.01 ± 0.82 μg/L vs. 3.94 ± 0.93 μg/L, t=5.304) in the treatment group were significantly lower than those in the control group ( P<0.01), and the walking distance of 6 minutes (450.66 ± 79.25 m vs. 384.49 ± 70.16 m, t=4.421) was significantly longer than that of the control group ( P<0.01). Conclusions:The Sini-Jia-Huanglian Decoction can improve the heart function and clinical symptoms of CHF patients with qi deficiency and blood stasis syndrome, and improve the clinical efficacy.

Objective:To observe the clinical effect of medium and long term visual quality after regional refractive multifocal intraocular lens (MIOL) implantation and compared with that of single focal intraocular lens (SMOL) implantation.Methods:A cohort study was conducted with 108 patients (141 eyes) who had undergone MIOL and SIOL implantation in First Affiliated Hospital of Zhengzhou University from August 2016 to August 2017.According to the implanted IOL, the patients were divided into the MIOL group (55 patients 76 eyes) and the SIOL group (53 patients 65 eyes). At 2 years after operation, the parameters of uncorrected far, intermediate and near vision, as well as corrected distant vision were assessed; the spherical equivalen was checked; the defocus curve of the operation eye was drawn; the high order aberrations (HOAs), Strehl ratio and modulation transfer function (MTF) were measured by i-Trace visual quality analyzer; contrast sensitivity of eyes was evaluated by a CSV-1000 contrast sensitivity instrument; visual quality between the two groups was compared by using the Chinese version of the American questionnaire on quality of Life after MIOL.This study was approved by the Ethics Committee of the First Affiliated Hospital of Zhengzhou University.Written informed consent was obtained from each patient prior to any medical examination. Results:The uncorrected intermediate and near visual acuity in the MIOL group was better than that in the SIOL group, with statistically significant difference(both at P<0.05). Two years after operation, the average defocus curve showed that there were two peaks at 0.0 D and -3.0 D in the MIOL group, and formed a wide platform between 0.0 and -3.0 D, and the downward trend was gentle.Under the pupil diameter of 5 mm, HOAs, coma, trefoil and secondary astigmatism in the MIOL group were higher than those in the SIOL group (all at P<0.05). Strehl ratio in the MIOL group was significantly lower than that in the SIOL group, with statistically significant difference ( P<0.05). Under the pupil diameter of 5 mm, MTF values of spatial frequencies of 5, 10, 15, 20, 25 and 30 c/d in the MIOL group were slightly lower than those in the SIOL group, without statistically significant differences (all at P>0.05). There was no significant difference in contrast sensitivity (3, 6, 12 and 18 c/d) between the two groups under photopic or mesopic conditions and with or without glare (all at P>0.05). The proportion of glasses removed in the MIOL group was 98.18%, which was significantly higher than that in the SIOL group (52.83%) by questionnaire ( χ2=30.37, P<0.01). The incidence of visual interference symptoms, such as glare and halo was 7.27% (4/55) in the MIOL group and 1.89% (1/53) in the SIOL group, respectively, with no statistically significant difference ( χ2=0.76, P=0.382). The satisfaction scores of vision at near distance vision, medium distance vision and overall visual acuity in the MIOL group were higher than that in the SIOL group, with statistically significant differences (all at P<0.05). Conclusions:Compared with SIOL implantation, regional refraction MIOL implantation can provide better and more stable mediate and near vision, a better contrast sensitivity, a lower incidence of optical interference and a higher postoperative satisfaction.
