Objective:To explore the distribution and determinants of abnormal blood lipid metabolism among flying personnel with lumbar disc herniation and with different flying hours and to provide data for targeted intervention strategies.Methods:The hospitalization data of 214 male flying personnel was retrospectively analyzed who were admitted to the Air Force Medical Center between September 2020 and September 2023, diagnosed with lumbar intervertebral disc protrusion, and underwent blood lipid testing within 24 h of admission. According to the hours of flying, they were divided into <1 000 h group (45 cases), 1 000-<3 000 h group (107 cases), and ≥3 000 h group (62 cases). The blood lipid biochemical indicators [total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol (non-HDL-C)], basic information and personal history of the flying personnel were collected. The detection rates of blood lipid metabolism disorders among flying personnel with different durations of flight were compared. The chi-square test for linear trend was used to find out whether there was a trend of linear changes in the detection rates of various blood lipid disorders. The multivariate Logistic regression analysis was conducted to analyze the determinants of abnormal blood lipid metabolism.Results:There were significant differences in age, levels of total cholesterol and low-density lipoprotein cholesterol, and non-HDL-C between flying personnel in different flying hours groups ( F=80.76, 4.67, 4.00, 6.35, P<0.001,=0.010, 0.020, 0.002). The levels of total cholesterol and low-density lipoprotein cholesterol, and non-HDL-C in the 1 000-<3 000 h group were higher than those in the <1 000 h group ( P=0.023, 0.029, 0.003). The total detection rate of elevated triglyceride was the highest (28.04%). There was a significant difference in the detection rate of elevated low-density lipoprotein cholesterol between the 3 groups ( χ2=6.50, P=0.039), which was lower in the 1 000-<3 000 h group than in the <1 000 h group ( P=0.010). The results of the chi-square analysis of linear association showed that with the increase of flight duration, there was a linear decrease in the detection rates of elevated total cholesterol and elevated non-HDL-C ( χ2=4.17, 4.16, P=0.041, 0.041). The univariate Logistic regression analysis showed that compared with the <1 000 h, the 1 000-<3 000 h was an influencing factor for elevated triglyceride ( OR=4.406, 95% CI: 1.604-12.103) and elevated non-HDL-C ( OR=6.217, 95% CI: 1.403-27.551) while body mass index was an influencing factor for elevated total cholesterol ( OR=1.237, 95% CI: 1.055-1.450) and elevated non-HDL-C ( OR=1.298, 95% CI: 1.087-1.548). Current smoking was an influencing factor for elevated triglyceride ( OR=3.214, 95% CI:1.700-6.078) and decreased high-density lipoprotein cholesterol ( OR=3.200, 95% CI: 1.724-5.941). The multivariate Logistic regression analysis showed that body mass index was a risk factor for elevated total cholesterol ( OR=1.245, 95% CI: 1.054-1.471) and elevated non-HDL-C ( OR=1.301, 95% CI: 1.082-1.564). Current smoking was a risk factor for elevated triglyceride ( OR=3.439, 95% CI: 1.550-7.631) and decreased high-density lipoprotein cholesterol ( OR=4.047, 95% CI: 1.901-8.729). Conclusions:Flying personnel with lumbar intervertebral disc protrusion and with different flying hours exhibit distinct features of phased blood lipid metabolism disorders. The triglyceride levels of those with 1 000-<3 000 h deserve more attention while the levels of low-density lipoprotein cholesterol should be brought under control for those with <1 000 h. It is recommended that hierarchical interventions be exercised according to flight stages, and that priority be given to controlling daily adjustable behavioral factors such as body mass index and smoking.

Objective:To investigate the correlation of serum interleukin-6 (IL-6) and homocysteine (Hcy) levels, monocyte-to-lymphocyte ratio (MLR), and serum lipid levels [triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels] with ulcerative colitis.Methods:The clinical data of 98 patients with ulcerative colitis admitted to Bayannur Hospital from November 2021 to November 2023 (observation group) were retrospectively analyzed. Forty-nine healthy individuals who were selected at a 2:1 ratio during the same period were included in the control group. Serum IL-6 and Hcy levels, MLR, and lipid levels were compared between the two groups. The diagnostic efficacy of serum IL-6, Hcy, MLR, and lipid levels for ulcerative colitis was assessed using receiver operating characteristic (ROC) curves. Additionally, Pearson correlation analysis was conducted to analyze correlation of serum IL-6 and Hcy levels, MLR, and lipid levels with ulcerative colitis.Results:In the observation group, serum IL-6 and Hcy levels and MLR were (39.87 ± 12.36) pg/mL, (13.01 ± 3.52) μmol/L, and (0.38 ± 0.12), respectively, all of which were significantly higher than those in the control group [(22.3 ± 3.26) pg/mL, (10.05 ± 3.26) μmol/L, (0.29 ± 0.08), t = 9.77, 4.92, 4.78, all P < 0.05]. In the observation group, serum levels of TG, TC, LDL-C, and HDL-C levels were (1.16 ± 0.32) mmol/L, (4.12 ± 1.15) mmol/L, (2.60 ± 0.75) mmol/L, and (1.02 ± 0.17) mmol/L, respectively, all of which were significantly lower than those in the control group [(1.45 ± 0.41) mmol/L, (4.91 ± 0.99) mmol/L, (3.20 ± 0.71) mmol/L, (1.13 ± 0.16) mmol/L, t = 4.71, 4.11, 4.65, 3.77, all P < 0.05]. ROC curve analysis indicated that the areas under the curve (AUC) for diagnosing ulcerative colitis based on serum levels of IL-6, Hcy, MLR, TG, TC, LDL-C, and HDL-C were 0.957, 0.749, 0.746, 0.732, 0.678, 0.722, and 0.681, respectively. Pearson correlation analysis showed that serum levels of IL-6, Hcy, MLR, TG, TC, LDL-C, and HDL-C were all correlated with the severity of ulcerative colitis in patients ( r = 0.501, 0.615, 0.605, -0.577, -0.542, -0.548, -0.646, all P < 0.05). Additionally, serum levels of IL-6, Hcy, and MLR were negatively correlated with lipid levels ( r = -0.806, -0.801, -0.791, -0.649, -0.728, -0.671, -0.720, -0.655, -0.857, -0.877, -0.889, -0.583, all P < 0.05). Conclusions:In patients with ulcerative colitis, serum levels of IL-6, Hcy, and MLR are elevated, while lipid levels are decreased. Additionally, serum levels of IL-6, Hcy, MLR, and lipid levels are associated with the severity of the disease. There is also a correlation between serum levels of IL-6, Hcy, MLR, and lipid levels.

Objective:To verify the effect of Fu′s massage combined with physical therapy technology in rapidly relieving neck and low back pain caused by long-haul flight.Methods:Forty-two male volunteers were divided into 8, 12, 16, 24 and 48 h groups according to the simulated flying hours. After the completion of the simulated long-haul flight, the 5 groups of volunteers were immediately treated with Fu′s massage combined with physical factors for neck and low back pain. The Visual Analogue Scale (VAS) was used to evaluate the cervical and lumbar pain of volunteers after simulated flight and after treatment, and the treatment effect was before treatment analyzed.Results:There were significant differences in the VAS scores of cervical and lumbar regions before treatment among volunteers with different flying hours ( H=-30.15, -28.25, both P<0.001). The VAS scores of cervical and lumbar regions of volunteers in the 24 h and 48 h groups were higher than those in the 8 h group ( P=0.002, <0.001, =0.002, <0.001). The VAS scores of cervical and lumbar regions of volunteers in the 48 h group were higher than those in the 12 h group ( P=0.016, 0.001). The VAS score of cervical region of volunteers in the 48 h group was higher than that in the 16 h group ( P=0.033). After the intervention of Fu's massage combined with physical therapy, the VAS scores of cervical and lumbar regions in each group were lower than those before treatment, and the differences were significant ( t/ Z=-3.00-17.00, all P<0.05 or 0.01). Conclusions:Fu′s massage manipulation combined with physical treatment can effectively relieve the neck and low back pain caused by long-haul flight, which can be widely used as a relief method.

  Objective  To understand the current status of surgical treatment for hemophilia osteoarthropathy (HO) in China.  Methods  Using an online questionnaire, select domestic hospitals that partici-pated in the compilation of the 'Guideline for perioperative management of hemophilia patients undergoing orthopaedic surgery in China ', in addition to members of the National Joint Surgery Group, and the Orthopedic Branch of the Chinese Medical Association for targeted investigation and analysis.  Results  A total of 17 domestic hospitals were included, all of which were general hospitals. Hospitals that started HO surgery treatment before 2000 accounted for 35.29%. A total of 3057 surgical cases of HO were reported by those hospitals. The most commonly performed surgical procedures were hip and knee joint replacement. The most commonly used coagulation factor replacement regimen was recombinant coagulation factor preparation. Ten hospitals reported finding patients with transfusion-related infectious diseases. Bleeding and hematoma formation were the most frequently reported surgical complications. Excessive length of hospital stay and high economic costs were the most frequently reported problems.  Conclusions  Surgical treatment for HO in 17 hospitals is mainly carried out in some large comprehensive medical centers in the eastern region. Compared with the patient base, the popularity and number of surgeries are still relatively insufficient. It is necessary to further standardize the treatment system by standardizing factor replacement and strengthening rehabilitation to improve surgical treatment outcomes.

Objective:To investigate the efficacy of strength training with physical therapy in the treatment of nonspecific low back pain in pilots.Methods:A non-randomized, parallel controlled study was used. The pilots with mild and moderate nonspecific low back pain were selected from the aviation unit by questionnaire survey. They were grouped on a voluntary basis. In the comprehensive treatment group, pilots were treated for 3 months, including strength training and physical therapy. In the control group, pilots who did not participate in the rehabilitation program, lived and worked according to daily conditions, and they were not restricted by strength training and physical therapy. The Visual Analogue Scale (VAS) pain scores, McGill Pain Questionnaire (MPQ) scores and low back muscle strength were compared between the 2 groups of pilots before and after treatment.Results:A total of 109 pilots were selected, among which 21 pilots volunteered to join the comprehensive treatment group and 88 pilots in the control group. Before treatment, there was no significant difference in VAS pain scores and MPQ scores between the 2 groups of pilots (both P>0.05). After treatment, the VAS pain scores and MPQ scores of the comprehensive treatment group were lower than those in the control group, and the difference was significant ( t=1.98, 2.31, P=0.048, 0.021). Before treatment, there was no significant difference in low back muscle strength between the 2 groups of pilots ( P>0.05). After treatment, the increments in maximum strength of left flexion, right flexion, and posterior extension of pilots in the comprehensive treatment group was higher than those in the control group, and the differences were statistically significant ( U=2.17, 2.47, 3.64, P=0.002, 0.013,<0.001). Conclusions:Strength training with physical therapy can effectively alleviate nonspecific low back pain in pilots and improve the strength of waist muscles. It can be promoted and applied in the prevention and treatment of nonspecific low back pain in pilots.
