Objective To analyze the effect of graded exercise rehabilitation in patients with acute exacerbation of chronic obstructive pulmonary disease,and to provide references for clinical nursing practice.Methods A total of 70 patients with acute exacerbation of chronic obstructive pulmonary disease who met the criteria in the Department of Respiratory Medicine of a tertiary hospital in Zunyi City from September to December 2023 were randomly divided into an experimental group and a control group(with 35 cases in each group).The experimental group implemented graded exercise rehabilitation based on the Global Chronic Obstructive Pulmonary Initiative guidelines,and the control group implemented routine exercise rehabilitation.After intervention,the lung function,blood gas analysis,oxygenation index,6 min walking test and the incidence of complications related to non-invasive mechanical ventilation were compared between the 2 groups.Results Finally,34 cases were included in the experimental group and 35 cases in the control group.After intervention,the forced expiratory volume in the first second of the experimental group was improved compared with the control group(P＜0.05).The 6-minute walking test of the experimental group was higher than that of the control group(P＜0.05).The total incidence of non-invasive mechanical ventilation-related complications in the experimental group was lower than that in the control group(P＜0.05).There was no significant difference in blood gas analysis and oxygenation index between the 2 groups(P＜0.05).Conclusion The implementation of graded exercise rehabilitation based on the Global Chronic Obstructive Pulmonary Initiative guidelines can help patients with acute exacerbation of chronic obstructive pulmonary disease improve their respiratory function,improve their exercise endurance,and reduce non-invasive mechanical ventilation-related complications.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To investigate the efficacy and safety of nerve decompression surgery through the lateral-rectus approach for sacral plexus nerve injury after sacral fracture fixation.Methods:A retrospective study was conducted to analyze the 10 patients with combined sacral plexus nerve injury after sacral fracture fixation who had been admitted to Department of Orthopedics, Xiangya Hospital between May 2022 and May 2023. There were 2 males and 8 females with an age of 16.5 (15.0, 26.3) years. At the time of injury, the patients had been clearly diagnosed as sacral fracture combined with sacral plexus nerve injury. By the Denis classification of sacral fractures: 7 cases of type Ⅱ and 3 cases of type Ⅲ; sacral plexus nerve injury sites: 1 case of L 4, 8 cases of L 5, 7 cases of S 1, and 2 cases of S 2. All of them were treated with reduction and internal fixation via the posterior approach within 2 weeks after injury, but after surgery their manifestations of sacral plexus nerve injury still persisted which were confirmed by CT, magnetic resonance imaging and neuromuscular electromyography. Therefore, at (4.0±2.3) months after internal fixation, all patients were treated with nerve decompression surgery through the lateral-rectus approach. The operative time, intraoperative bleeding, length of hospitalization, Gibbons nerve damage score and neurological recovery at the last follow-up were recorded. Results:In the 10 patients, the operative time was (112.0±21.5) min, intraoperative bleeding (215.0±91.3) mL, and length of hospitalization 7.0 (6.0, 8.5) d. Intraoperatively, sacral plexus nerve compression was found in 9 cases (6 cases of nerve compression and pulling due to fracture displacement, 3 cases of nerve entrapment due to soft tissue scar adhesion), and 1 case of nerve root avulsion injury. No other intraoperative complications occurred. The 10 patients were followed up for (9.2±2.3) months after surgery. At the last follow-up, the Gibbons score for the 10 patients improved from preoperative 3.0 (3.0, 3.3) points to 1.0 (1.0, 2.0) point, and their British Medical Research Council (BMRC) nerve injury grading was improved from the preoperative grade 0.0 (0.0, 1.3) to grade 3.5 (2.8, 4.0) (1 case of M5, 4 cases of M4, 4 cases of M3, and 1 case of M2).Conclusion:The lateral-rectus approach is effective and safe for exploration and decompression of the sacral plexus nerve in patients combined with sacral plexus nerve injury despite sacral fracture fixation.

Objective:Lung cancer is characterized by its high incidence and case fatality rate.Factors related to population composition and cancer prevention programme policy have an effect on the incidence and diagnosis of lung cancer.This study aims to provide scientific support for early diagnosis and treatment of lung cancer by investigating the clinic information,pathological,and imaging characteristics of surgical patients with lung cancer. Methods:The data of 2 058 patients,who underwent surgery for lung cancer in the Department of Thoracic Surgery of Xiangya Hospital of Central South University from 2016 to 2019,were retrospectively collected to analyze changes in clinic information,pathological,and imaging characteristics. Results:From 2016 to 2019,the number of patients per year was 280,376,524,and 878,respectively.Adenocarcinoma(68.1%)was the most common pathological type of surgical patients with lung cancer.From 2016 to 2019,the proportion of adenocarcinoma was increased from 55.5%to 74.1%.The proportion lung cancer patients in stage IA was increased from 38.9%to 62.3%,and the proportion of patients who underwent sublobar resection was increased from 1.8%to 8.6%.The proportion of lymph node sampling was increased in 2019.Compared with the rate in 2016,the detection rate of nodules with diameter≤1 cm detected by CT before surgery in 2019 was significantly improved(2.0%vs 18.2%),and the detection rate of nodules with diameter>3 cm was decreased(34.7%vs 18.3%).From 2016 to 2019,the proportion of lesions with pure ground-glass density and partial solid density detected by CT was increased from 2.0%and 16.6%to 20.0%and 37.3%,respectively.The proportion of solid density was decreased from 81.4%to 42.7%. Conclusion:The number of lung cancer surgery patients is rapidly increasing year by year,the proportion of CT-detected purely ground-glass density and partially solid density lesions are increasing,the proportion of patients with adenocarcinoma is rising,the proportion of early-stage lung cancer is increasing,smaller lung cancers are detected in earlier clinical stage leading to a more minimally invasive approach to the surgical methods.

Objective To investigate the therapeutic effect of segmental decompression combined with corrective short-segment fusion surgery for the treatment of degenerative lumbar scoliosis.Methods In total,124 patients with degenerative lumbar scoliosis were selected and divided into short-and long-segment fusion groups using the random number table method,with 62 patients in each group.Posterior short-segment decompression,fixation,and fusion were performed in the short-segment fusion group;the fusion segment was the adjacent lumbar vertebra.Posterior long-segment decompression,fixation,and fusion were performed in the long-segment fusion group;the fusion segments included multiple adjacent lumbar vertebrae.At the 6th month after surgery,the coronal Cobb angle of lumbar convexity,sagittal Cobb angle of lumbar lordosis,intervertebral foramen height,intervertebral space height,intervertebral foramen area,spinal canal area,spinal canal diameter,Japanese Orthopedic Association(JOA)score,Oswestry Disability Index(ODI),degree of pain in the lower back and lower limbs,and postoperative complications were compared between the groups.Results The Cobb angle of the coronal lumbar scoliosis in the short-and long-segment fusion groups was significantly higher than that before surgery(P<0.05).At the 6th month after surgery,the intervertebral foramen height,intervertebral space height,intervertebral foramen area,spinal canal area,and spinal canal diameter in both groups increased,and those in the short-segment fusion group were higher than those in the long-segment fusion group(P<0.05);at the 6th month after the operation,the JOA scores of the short-segment and long-segment fusion groups were higher than those before surgery,and the JOA score of the short-segment fusion group was higher than that of the long-segment fusion group(P<0.05).The ODI score was lower than that before surgery in the short-and long-segment fusion groups,and the ODI score in the short-segment fusion group was lower than that in the long-segment fusion group(P<0.05).At the 6th month after surgery,the pain scores of the lower back and lower limbs in the short-and long-segment fusion groups were significantly higher than those before surgery(P<0.05).There were two cases of dural tears during decompression caused by lamina dura adhesion in the long-segment fusion group,and no serious complications were observed in the short-segment fusion group.Conclusions Both short-and long-segment decompression fixation fusion using a posterior approach can achieve good therapeutic effects for treating degenerative lumbar scoliosis.However,compared to the long-segment fusion group,the short-segment fusion group undergoing short-segment decompression fixation fusion through a posterior approach had a shorter surgical period,lower intraoperative blood loss,better recovery of lumbar function,and a lower risk of postoperative complications.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

OBJECTIVE: To examine the association of handgrip strength with aortic stenosis incidence among adults aged 60 years and older. METHODS: We conducted a cohort study using the UK Biobank data to assess the relationship between handgrip strength and incident aortic stenosis in individuals aged 60 years and older. Handgrip strength was measured using a Jamar J00105 hydraulic hand dynamometer. Adjusted Cox proportional hazards regression models were conducted to assess the association between handgrip strength and incident aortic stenosis. RESULTS: We included 157,097 UK Biobank participants (78,151 women and 78,946 men) in our study, with mean age of 64 ± 2.9 years. During a median follow-up of 8.1 (7.4-8.8) years, 1543 (1.0%) participants developed incident aortic stenosis. Compared with those with the lowest handgrip strength (tertile 1), the adjusted hazard ratios (95% confidence interval) of incident aortic stenosis in the middle (tertile 2) and the highest (tertile 3) were 0.86 (0.77-0.97) and 0.76 (0.67-0.87), respectively. CONCLUSIONS Higher handgrip strength was associated with lower risk of developing aortic stenosis in older adults. Future studies warrant preventive strategies for older adults with lower handgrip strength.
