Intelligent acupuncture-moxibustion medical equipment is an important force in promoting the inheritance, innovation, and modernization of acupuncture-moxibustion. This paper reviews the development status of intelligent acupuncture-moxibustion medical equipment and related new technologies, as well as the challenges faced. It is found that, with the advancement of technologies such as big data and artificial intelligence, acupuncture-moxibustion medical equipment has shown characteristics of greater precision, miniaturization, intelligence, and portability. However, deficiencies remain in areas such as standardization and regulation, including relatively low rates of effective transformation and a lack of innovation in research outcomes. Therefore, there is an urgent need to formulate corresponding strategies: improving the development of relevant standards for intelligent acupuncture-moxibustion medical equipment, encouraging the integration of medicine and engineering, cultivating interdisciplinary talents, and strengthening the protection of invention patents. It is necessary to establish a demand-oriented pathway connecting "equipment development, equipment evaluation, product formation" through multiple stages such as talent training and research project initiation, thereby promoting the modernization and standardization of intelligent acupuncture-moxibustion medical equipment and supporting the revitalization of traditional medicine.

OBJECTIVE: To compare the short-term effectiveness between Gamma 3 intramedullary nails and Gamma 3 U-Blade system in the treatment of osteoporotic intertrochanteric fractures in the elderly. METHODS: A retrospective analysis was conducted on the clinical data of 124 elderly patients with osteoporotic intertrochanteric fractures, who were admitted between February 2020 and February 2023 and met the selection criteria. The fractures were fixed with Gamma 3 intramedullary nails in 65 patients (control group) and Gamma 3 U-Blade systems in 59 patients (UB group). The differences between the two groups were not significant in age, gender, body mass index, American Society of Anesthesiologists (ASA) classification, bone mineral density, time from injury to operation, fracture classification, and affected side ( P>0.05). The operation time, intraoperative blood loss, hospital stay, and fracture healing time were recorded; the tip-apex distance, fracture reduction quality, and lag screw position were evaluated on X-ray films at immediate after operation; the lag screw sliding distance and change value of neck-shaft angle were measured on X-ray films at last follow-up. Harris hip score at 1 year after operation and the occurrence of internal fixation-related complications were compared between the two groups. RESULTS: The operation time, intraoperative blood loss, and hospital stay in the UB group increased compared to the control group, but the differences were not significant ( P>0.05). All patients in both groups were followed up 12-24 months (mean, 17.1 months). At 12 months after operation, there was no significant difference in the Harris hip score between the two groups ( P<0.05). Radiological examination showed that there was no significant difference between the two groups ( P>0.05) in terms of tip-apex distance, fracture reduction quality, and lag screw position. Fractures healed in both groups, and there was no significant difference in healing time ( P>0.05). At last follow-up, the change value of neck-shaft angle and lag screw sliding distance in the UB group were significantly lower than those in the control group ( P<0.05). During follow-up, no related complications occurred in the UB group, while 6 cases (9.2%) in the control group experienced complications, and the difference in the incidence was significant ( P<0.05). CONCLUSION For the osteoporotic intertrochanteric fractures in the elderly, the Gamma 3 U-Blade system fixation can achieve good short-term effectiveness, with better imaging results compared to Gamma 3 intramedullary nails fixation.

OBJECTIVE: To analyze the disease burden of pelvic fractures at the global, regional, and national levels from 1990 to 2023 using data from the 2023 Global Burden of Disease Study (GBD), and to predict the disease burden through 2050. METHODS: Leveraging data from the GBD 2023, this study investigated the disease burden of pelvic fractures across 204 countries and regions. Assessment indicators included incidence rate, prevalence rate, and years lived with disability (YLDs). The Joinpoint regression model was employed to analyze trends in pelvic fracture burden from 1990 to 2023, while the average annual percentage change (AAPC) was used to quantify this temporal trend. The relationship between the socio-demographic index and pelvic fracture burden was evaluated. Furthermore, the long short-term memory (LSTM) model was applied to predict trends in pelvic fracture burden through 2050. RESULTS: In 2023, the estimated number of new pelvic fracture cases globally was 7 479 884 [95% uncertainty interval ( UI): 5 293 401-10 611 876], representing a 42.74% increase from 1990. In the same year, the number of prevalent pelvic fracture cases and YLDs were 23 007 508 (95% UI: 21 021 518-25 327 165) and 3 909 228 person-years (95% UI: 2 725 498-5 194 385), respectively. Additionally, age-standardized rates exhibited an opposing downward trend. Significant disparities in the disease burden of pelvic fractures were identified across different age groups, genders, and social contexts. According to predictions from the LSTM model, the global age-standardized incidence rate (ASIR) of pelvic fractures will be approximately 88.44 per 100 000 persons by 2050, while the total number of incident cases will rise to 8 547 095. CONCLUSION Although the overall incidence rate, prevalence rate, and YLDs of pelvic fractures have exhibited an upward trend over the past three decades, the ASIR, age-standardized prevalence rate (ASPR), and age-standardized years of life lost rate (ASYR) have shown a downward trend. It is predicted that over the upcoming 26-year period, the age-standardized rate of disease burden due to pelvic fractures will further decrease, while the number of incident cases and prevalent cases will continue to exhibit an upward trend. Formulating more targeted disease prevention strategies is critical to addressing disparities across genders, regions, and other dimensions, and to mitigating the burden of pelvic fractures.

OBJECTIVE: This review summarized the first 10-year progresses and controversies in the concept of anteromedial cortical support reduction, to provide references for further study and clinical applications. METHODS: Relevant domestic and foreign literature on cortical support reduction was extensively reviewed to summarize the definition of positive, neutral, and negative support, anteromedial cortices at the inferior corner, intraoperative technical tips for fracture reduction, radiographic assessment at different periods, comparison between positive versus neutral and medial versus anterior support, and the clinical efficacy of Chang reduction quality criteria (CRQC) and postoperative stability score. RESULTS: Anteromedial cortical support reduction was only focused on the cortex of anteromedial inferior corner, with no concern the status of lateral wall or lesser trochanter. Anteromedial cortex was seldom involved by fracture comminution, it was thicker, denser, and stronger, and was the key for mechanical buttress of the head-neck fragment to share compression load. Positive, neutral, and negative support were also called "extramedullary, anatomic, and intramedullary reduction", respectively. There was hardly seen parallel cortical apposition, but characterized by some kinds of head-neck rotation, for example 10°-15° flexed rotation for positive cortical contact and support. Due to intraoperative compression and postoperative impaction, the status of cortical support may be changed at different time of radiographic examination. The positive medial cortex support was more reliable with less reduction loss than its neutral counterpart, and the anterior cortex contact was more predictive than the medial cortex for final results. As incorporation the bearing of cortex apposition and using a 4-point score, CRQC demonstrated more efficacy and was gradually accepted and applied in the evaluation of trochanteric fracture reduction quality. Postoperative stability score (8 points) provided a assessment tool for early weight-bearing in safety to prevent mechanical failure. CONCLUSION Anteromedial cortical support reduction is a key point for stability reconstruction in the treatment of trochanteric femur fractures. Evidence has definitely shown that non-negative (positive and neutral) is superior to negative (loss of cortical support). There is a tendency that positive cortex support is superior to neutral, but high quality study with large sample size is needed for a clear conclusion.

Objective:To explore the effects of posterior malleolar fracture fixation on the rotational stability of the ankle joint.Methods:A total of 20 fresh cadaveric specimens of lower limbs were anatomized to measure the area of attachment of the posterior inferior tibiofibular ligament and transverse ligament complex to the posterior surface of the tibia. One healthy volunteer was selected to construct a finite element model for the intact tibiofibular and ankle joints and finite element models for posterior malleolar fracture with different posterior projection areas. A load of 600 N was vertically applied to the inferior calcaneus along the tibial mechanical axis. The contact area and maximum Von Mises stress of the distal tibial articular surface were analyzed to verify the validity of the model for the intact tibiofibular and ankle joints. In the finite element models for the posterior malleolar fracture (S, 1/2S, 1/4S, 1/8S and 1/16S model groups, with S standing for the complete projection area of the ligament complex on the posterior surface of the tibia), the width increase in the tibiofibular clear space was measured when a vertical load of 600 N and external rotation load of 5 N·m were applied to the ankle joint after the reduction and fixation of posterior malleolar fracture. The cutoff value of the posterior projection area of posterior malleolar fracture that could maintain the rotational stability of the ankle joint was assessed.Results:The measurement results of the cadaveric specimens showed that the area of attachment of the posterior inferior tibiofibular ligament and transverse ligament complex to the posterior surface of the tibia was relatively large. It was attached to the posterolateral area of the distal tibia with the highest point located at (45.2±5.6)mm from the articular surface. With the increase in the distance from the joint line, the width of the posterior attachment area of the ligament complex was decreased. Results of the finite element analysis showed that in the finite element model for the intact tibiofibular and ankle joints, the tibiotalar joint contact area was 324.02 mm 2 and the maximum Von Mises stress was 4.495 1 MPa with a vertical load of 600 N. In the finite element models for the posterior malleolar fracture, the distal tibiofibular clear spaces of the S, 1/2S, 1/4S and 1/8S model groups increased by less than 2 mm following loading, while it was increased by 3.445 8 mm in the 1/16S model group. The cutoff value of the posterior tibial projection area that could maintain the rotational stability of the ankle joint was 1/8S. Conclusions:The attachment area of the posterior inferior tibiofibular ligament and transverse ligament complex to the posterior surface of the tibia is large. Both the axial stability and rotational stability of the ankle joint should be considered in the treatment selection for posterior malleolar fracture. Simple posterior malleolar fixation is recommended to restore the rotational stability and axial stability of the ankle joint when tibiofibular syndesmosis is unstable and the cutoff value is larger than or equal to 1/8, while tibiofibular syndesmosis screws must be implanted when tibiofibular syndesmosis is unstable and the cutoff value is less than 1/8.

Respiratory diseases(e.g.,lung inflammation and pulmonary fibrosis)are a serious threat to human health.Mitochondria,organelles unique to eukaryotic cells,not only have important functions in energy production,biosynthesis,and the maintenance of intracellular homeostasis but also act as diverse signaling organelles involved in inflammation,proliferation,differentiation,cell repair,and other processes.The mitochondrial quality control system involves mitochondrial biogenesis,dynamics,and autophagy.Certain pathological mechanisms of respiratory diseases,such as oxidative stress and inflammation,are closely related to the dysregulation of mitochondrial quality control systems.This paper summarizes the progress of research into mitochondrial quality control dysregulation in respiratory diseases(chronic obstructive pulmonary disease,pulmonary fibrosis,acute lung injury,asthma,and bacterial pneumonia)to explore new ideas for the prevention and treatment of respiratory diseases.

Objective To investigate the effects of calcitriol intervention on PI3K/AKT signaling pathway and wound healing in rats with diabetic foot ulcer(DFU).Methods Thirty-two male SD rats were divided into normal control(Con)group,DFU group,calcitriol low dose(L)group and calcitriol high dose(H)group.A circular wound of 5 mm in diameter and deep to the fascia was made on the dorsum of the left foot of rats in each group.HE staining was used to evaluate the histopathological changes of the wounds.Immunohistochemical method was selected to compare the distribution of CD34-positive cells and the expression of p-PI3K and p-AKT in traumatic tissues of each group.ELISA was adopted in the detection of serum IL-6,IFN-γ,TNF-α and IL-7.RT-PCR was used to detect the mRNA expression of PI3K and AKT in each group,and western blot was used to detect the protein expression of PI3K,p-PI3K,AKT,p-AKT and VEGF.Results Compared with Con group,the expressions of IL-6,IFN-γ,TNF-α,IL-7,CD34,PI3K mRNA,AKT mRNA,p-AKT protein,p-PI3K protein,p-PI3K/PI3K,p-AKT/AKT increased,while PI3K protein expression decreased in DFU,L and H groups(P<0.05),VEGF and AKT protein expression decreased in DFV and L groups(P<0.05).Compared with DFU group,the expressions of VEGF,AKT and PI3K protein increased(P<0.05),while the expressions of p-PI3K/PI3K,p-AKT/AKT decreased in L and H groups(P<0.05),IL-6 decreased in L group(P<0.05),and CD34 expression increased in H group(P<0.05),while IL-6,IFN-γ,TNF-α and IL-7,PI3K mRNA,AKT mRNA,p-AKT protein and p-PI3K protein expression decreased(P<0.05).Compared with L group,the expressions of CD34,VEGF,AKT and PI3K protein increased(P<0.05),while IL-6,PI3K mRNA,AKT mRNA,p-AKT protein,p-PI3K protein,p-PI3K/PI3K and p-AKT/AKT decreased in H group(P<0.05).Conclusions Calcitriol intervention may reduce the activity of the PI3K/AKT signaling pathway,inhibit inflammation,promote neovascularization,and facilitate wound healing in rats with DFU.

Objective:To compare the effectiveness of awake prone positioning (APP) care combined with standardized nursing and standardized nursing care in the prevention of early postoperative pulmonary complications (PPCs) in elderly patients with hip fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 84 elderly patients with hip fracture Admitted to Zhongda Hospital Affiliated to Southeast University from February 2021 to August 2021. There were 31 males and 53 females, aged 67-96 years [(82.3±6.3)years]. Fracture types were femoral neck fracture ( n=45) and intertrochanteric fracture ( n=39). Surgical procedures included closed reduction internal fixation ( n=39), hip hemiarthroplasty ( n=35), and total hip arthroplasty ( n=10). Among them, 42 patients received standardized nursing care and APP intervention (APP combined with standardized nursing care group), while the remaining 42 patients received standardized nursing care only (standardized nursing care group). The incidence rate of PPCs (including pneumonia, respiratory failure, pleural effusion, atelectasis and pulmonary edema) within 30 postoperative days, arterial oxygen pressure (PaO 2), arterial carbon dioxide pressure (PaCO 2), arterial oxygen saturation (SaO 2) on the 4th postoperative day, difference in PaO 2 between the 4th postoperative day and emergency visit, clinical pulmonary infection score (CPIS) on the 4th postoperative day, and number of adverse events related to APP were compared between the two groups. Results:All the patients were followed up for 30-90 days [(86.1±16.5)days]. The incidence rates of PPCs and type 1 postoperative respiratory failure in the APP combined with standardized nursing care group were 16.7% (7/42) and 4.8% (2/42), and were 35.7% (15/42) and 21.4% (9/42) in the standardized nursing care group (all P<0.05). The PaO 2 and SaO 2 on the 4th postoperative day, and difference in PaO 2 between the 4th postoperative day and emergency visit were (82.0±8.8)mmHg, 0.96±0.01, and 3.2 (-1.9, 8.0)mmHg in the APP combined with standardized nursing care group, and were (74.3±12.1)mmHg, 0.94±0.03, and -7.6 (-17.2, 1.1)mmHg in the standardized nursing care group (all P<0.01). The CPIS on the 4th postoperative day was 2.0 (1.0, 3.0)points in the APP combined with standardized nursing care group and 4.0 (1.0, 7.0)points in the standardized nursing care group ( P<0.05). No statistically significant differences were observed in the incidence of pneumonia, type I respiratory failure, pleural effusion, atelectasis and pulmonary edema within 30 postoperative days, as well as PaCO 2 on the 4th postoperative day between the two groups (all P>0.05). None of the patients experienced adverse events related to APP. Conclusion:For elderly patients with hip fracture, compared with standardized nursing care, application of APP combined with standardized nursing care can significantly decrease the incidence rate of early PPCs, especially type I respiratory failure, and improve postoperative oxygenation.

Objective:To analyze the characteristics and risk factors of previous low-energy fractures in elderly patients with hip fractures admitted to our hospital.Methods:The data for this study was collected from 596 hip fracture patients admitted to Zhongda Hospital Affiliated to Southeast University between January 2018 and December 2021.Out of these patients, there were 404 females and 192 males.Based on the history of low-energy fracture before hip fracture, the patients were divided into two groups: a low-energy fracture group and a non-low-energy fracture group.A comparison was made between the two groups in terms of gender, age, fracture type, BMI, number of combined medical diseases, ASA score, and other characteristics.Results:The study included a total of 596 patients, with 368 patients having no history of low-energy fractures and 228 patients with low-energy fractures.Among the patients with low-energy fractures, there were 118 vertebral fractures, 69 hip fractures, 57 rib fractures, 19 radial fractures, 14 humerus fractures, and 12 patella fractures.Univariate analysis revealed significant differences in age, gender, fracture type, number of combined medical diseases, and ASA score between the two groups( P<0.05 for all). The results of multivariate Logistic analysis indicated that age( OR=1.046, 95% CI: 1.022-1.070), female sex( OR=1.474, 95% CI: 1.011-2.148), and the number of comorbid medical diseases( OR=1.211, 95% CI: 1.113-1.318)were independent risk factors for patients with a history of low-energy fractures. Conclusions:Our findings provide evidence that vertebral, hip, and rib fractures were the three most common previous low-energy fractures in elderly patients with hip fractures.We identified age, female gender, and number of medical diseases as independent risk factors for prior low-energy fractures in this population.

The data of a patient with autosomal dominant optic atrophy (ADOA) and chronic renal insufficiency caused by SSBP1 gene mutation in the Children′s Hospital Affiliated to Zhengzhou University in July 2021 was analyzed retrospectively.Literature was reviewed.The patient was a 10-year-old girl, who visited the hospital due to " growth retardation for the past 3 years and elevated serum creatinine (Scr) for the past 2 years" . On admission, the patient′s height was 130 cm (<10 th percentile of the same sex of healthy age) and her weight was 22 kg (<3 rd precentile of the same sex of healthy age). Lab examination showed that the level of blood urea nitrogen (BUN) was 16.3 mmol/L, Scr was 115.4 μmol/L, and the estimated glomerular filtration rate was 41 mL/(min·1.73 m 2). The patient was complicated with metabolic acidosis and mild anemia.Imaging findings showed small volume of both kidneys, increased background parenchymal enhancement, scattered spot-like hyperechoes and unclear boundary between the cortex and medulla.Additionally, the patient had a history of optic atrophy.Both the father and mother of the patient had no related phenotypes.The genetic test of the patient showed that c. 320G>A (p.R107Q) was a heterozygous missense mutation, which was spontaneous.A total of 5 English papers were retrieved.There were 8 kinds of SSBP1 gene mutations reported, including 7 heterozygous missense mutations [c.320G>A (p.Arg107Gln), c.119G>T (p.Gly40Val), c.331G>C (p.Glu111Gln), c.184A>G (p.Asn62Asp), c.113G>A (p.Arg38Gln), c.422G>A (p.Ser141Asn), c.79G>A (p.Glu27Lys)] and 1 homozygous mutation [c.394A>G (p.Ile132Val)]. Studies have established that almost all patients carrying SSBP1 mutations have manifestations of eye involvement, and that some patients are complicated with progressive deterioration of renal function, sensorineural deafness, growth retardation, and hypothyroidism.It suggests that SSBP1 gene mutation can cause ADOA.For patients with optic atrophy, whether they are complicated with hearing loss and growth retardation, renal morphology and renal function evaluation are recommended.Early genetic examination is helpful for diagnosis and treatment.
