Objective:To study the correlation between osteoporosis and the joint of small articular process of lumbar vertebra,and the correlation between bone mineral density(BMD)and various parameters of small joint based on quantitative computed tomography(QCT),so as to provide scientific basis for formulating clinically treatment strategies.Methods:This study included 63 patients who admitted to orthopedics of The Second Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from December 2023 to March 2024 due to waist discomfort and lower limb pain.According to BMD standard of CT examination for lumbar vertebra,these patients were divided into normal BMD group(31 cases),osteopenia group(21 cases)and osteoporosis group(11 cases).All patients underwent CT scan on lumbar vertebra.The mode with body membrane were adopted to measure BMD,the area of left and right articular process,CT value,height after the scan was completed.Whether existed osteophytes,endplate inflammation and intervertebral disc herniation in each group were checked.Univariate Analysis of Variance(ANOVA)was employed to assess the differences among different BMD groups in age,gender,area of articular process,CT value and height.The Pathria grading system was adopted to assess the degeneration degree of intervertebral joint,and the Fisher's exact test was used to analyze the differences in degeneration scores of articular process among three groups.At the same time,the pairwise comparison between groups also was conducted.Spearman's rank correlation analysis was conducted to explore the correlation between BMD and the degeneration degree of intervertebral joint.Results:The BMD value of normal BMD group was(165.14±30.11)mg/cm3,and that of osteopenia group was(98.98±10.14)mg/cm3,and that of osteoporosis group was(58.62±18.73)mg/cm3.There was a statistically significant difference in BMD value among three groups(F=103.121,P＜0.001),and there was a statistically significant difference in BMD value between normal BMD group and osteopenia group as the result of pairwise comparison between groups(t=10.018,P＜0.001).There was statistically significant difference in BMD value between normal BMD group and osteoporosis group(t=12.989,P＜0.001),and there was statistically significant difference in BMD value between osteopenia group and osteoporosis group(t=4.641,P＜0.001).The areas of left and right upper articular process of normal BMD group were less than that of other two groups,and the differences of CT value and height of left and right upper articular process among three groups were significant(F=27.350,24.458,P＜0.05),respectively.The CT value of normal BMD group was higher than that of other two groups,and CT values of right upper articular process of osteopenia group was significantly lower than that of osteoporosis group,and the difference was statistical significance(t=2.191,P＜0.05).The heights of left and right upper articular processes of normal BMD group were lower than those of osteoporosis group,and the height of right upper articular process was lower than that of osteopenia group(t=2.331,-2.798,-2.618,P＜0.05).There was a negative correlation between osteoporosis degree and the degeneration of articular process joints(r=-0.745,P＜0.001).With the decreasing of BMD value,the degeneration of articular process joint gradually aggravated,and the ratios of osteophytes,endplate inflammation and intervertebral discs increased.Conclusion:There is a certain correlation between the osteoporosis and the degeneration of articular process joints of lumbar intervertebral disc.The ratios of osteophytes,endplate inflammation and intervertebral disc herniation increase,and both the area and height of the left and right articular process increase when the reduction of bone mass reaches to a serious degree.

Depression is closely associated with a neuro-endocrine-immune(NEI)system imbalance.The"excessive vitality leading to restraint and counter-regulation(Kang Hai Cheng Zhi)"theory elucidates the self-regulating mechanism for maintaining dynamic equilibrium in the body,and serves as an importance principle guiding treatment formulation and medication selection.Based on the correlation between NEI system imbalance and the traditional Chinese medicine pathogenesis of depression,and integrating the"Kang Hai Cheng Zhi"theory,the author posits that the pathogenesis of depression lies in overactive liver invading spleen,earth dampness impeding wood′s ascendancy,and disharmony between body and mind,as well as imbalance in storage and discharge functions of liver and kidney,disharmony between Yin and Yang,and disrupted counter-regulation.This dosely aligns with two key pathological methanisms at the micro level:microglial-limbic system homeostatic imbalance and hypothalamic-pituitary-adrenal axis-inflammatory circuit dysregulation.Clinically,the treatment principle for depression adheres to supporting the counter-regulation to restrain excess,with herbal interventions using strategies such as restraining wood to support earth,dredging earth to unblock wood,and harmonizing pivotal functions,as well as nourishing water to nurture wood,warming kidney to tonify liver,and relieving depression to calm the spirit.These approaches aim to regulate the liver,spleen,and kidney,embodying the core therapeutic tenet of"striving for equilibrium,"thereby restoring the body′s self-regulating capability.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Objective:To identify the risk factors for acute graft-versus-host disease (aGVHD) in patients with acute myeloid leukemia (AML) undergoing haploidentical hematopoietic stem cell transplantation (HID-HSCT) .Methods:A total of 141 AML patients who underwent HID-HSCT at the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences, from January 2020 to July 2021 were included. The cumulative incidence of aGVHD was analyzed using the Fine-Gray competing risk model, with relapse and death as competing events, to compare differences between groups. Potential risk factors were evaluated by univariable and multivariable Cox proportional hazards regression analyses to determine their independent effects on aGVHD.Results:Among the 141 patients, 86 (61.0%) were male and 55 (39.0%) were female, with a median age at transplantation of 34 years. Within 100 days post-transplant, 59 patients developed grade Ⅱ-Ⅳ aGVHD, whereas 86 patients experienced no or grade Ⅰ aGVHD (the grade 0-Ⅰ aGVHD group) . Survival analysis showed that the 3-year overall survival was 68.7% (95% CI: 57.7%-81.9%) in the grade Ⅱ-Ⅳ aGVHD group, compared with 78.8% (95% CI: 70.4%-88.3%) in the grade 0 - Ⅰ aGVHD group, with the difference not being statistically significant ( P=0.190) . Univariable analysis identified donor age ( P=0.020, HR=1.020, 95% CI: 1.000-1.040) and the female donor-male recipient sex combination ( P=0.033, HR=1.980, 95% CI: 1.160-3.380) as risk factors for grade Ⅱ-Ⅳ aGVHD. Multivariable analysis confirmed that donor age ( P=0.005, HR=1.026, 95% CI: 1.008-1.047) and the female donor-male recipient sex combination ( P=0.002, HR=2.339, 95% CI: 1.354-4.037) were independent risk factors for aGVHD. Patients receiving grafts from donors aged >45 years had a significantly higher 100-day cumulative incidence of grade Ⅱ-Ⅳ aGVHD compared with those receiving grafts from donors ≤45 years [54.7% (95% CI: 42.3%-67.0%) vs 31.6% (95% CI: 21.0%-42.1%) , P=0.006]. Similarly, patients with the female donor-male recipient sex combination had a higher 100-day cumulative incidence of grade Ⅱ-Ⅳ aGVHD than those with other sex combinations [56.8% (95% CI: 40.4%-73.1%) vs 36.9% (95% CI: 27.5%-46.3%) , P=0.015]. Conclusion:Older donor age and the female donor-male recipient sex combination remain independent risk factors for aGVHD in patients with AML undergoing HID-HSCT.

Objective:To investigate the therapeutic effectiveness of double-anatomical plate-assisted reconstruction of a stable triangle in the treatment of chronic distal humerus fractures.Methods:A retrospective analysis was performed on the medical records of 10 patients with distal humerus fracture treated with double plate assisted reconstruction of a stable triangle from August 2021 to December 2024. All patients were followed up for more than 6 months. The cohort included 9 males and 1 female, with a mean age of 54.75±15.15 years (range, 31-73 years). Causes of injury: 4 cases of slip, 2 cases of high-energy fall, 3 cases of traffic accident, and 1 case of crush injury. According to the AO/OTA classification, all fractures were type C3, including 4 cases of C3.3 and 6 cases of C3.2. The operation duration, intraoperative blood loss, and length of hospital stay were recorded. Follow-up evaluations were conducted at 1, 3, and 6 months postoperatively and at the final follow-up. Radiographs were obtained to assess fracture reduction, healing, and implant positioning. Functional outcomes of the elbow were assessed using carrying angle, humeral condyle anteversion angle, modified trochleocapitellar index (mTCI), range of motion (ROM), visual analogue scale (VAS) for pain, Mayo elbow performance score (MEPS), and complication rates.Results:All 10 patients successfully completed the operation, with an average operation time of 221.75±48.73 min (range, 165-310 min), an average intraoperative blood loss of 462.50±215.05 ml (range 150-800 ml). 4 patients received blood transfusion. The average hospital stay was 10.75±2.55 d (range 6-14 d). The average carrying angle of 171.50°±5.37° (range 165°-179°) and the anterior angle of humeral condyle 39.75°±3.96° (range 34°-45°) were all within the standard range. At least one index in the mTCI was within the optimal range at the last follow-up. All patients were followed up with an average follow-up of 10.75±5.73 months (range 6-22 months). All 10 patients were healed after surgery with an average healing time of 4.75±2.05 months (range 3-9 months). At the final follow-up, the average elbow ROM was 93.75°±25.88° (range, 50°-115°), internal rotation was 83.13°±9.61° (range, 60°-90°), and external rotation was 88.13°±3.72° (range, 80°-90°). The mean VAS score was 0.63±0.92 (range, 0-2), and the average MEPS was 88.75±11.57 (range, 70-100), with 4 excellent, 4 good, and 2 fair outcomes, an excellent and good rate of 80%. Complications included one case of periarticular osteophyte formation, one case of transient ulnar nerve numbness that improved with conservative treatment, and three cases of occasional mild pain following increased activity. Conclusion Double-anatomical plate-assisted reconstruction of a stable triangle provides effective and stable fixation for chronic AO/OTA C3 distal humerus fractures. The short-term postoperative outcomes are satisfactory, with good functional recovery and a low complication rate.Conclusions:Double-anatomical plate-assisted reconstruction of a stable triangle provides effective and stable fixation for chronic AO/OTA C3 distal humerus fractures.

The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.
