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.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective To investigate the effects of long-term high altitude exposure on the composition and structure of the gut microbiota in rats in different intestinal segments,and to explore the key affected intestinal segments initially.Methods Six-week-old C57BL/6 mice were randomly divided into a control group(Control group)and a high altitude exposed group(HA group).The HA group was exposed to a low-pressure oxygen chamber at a simulated altitude of 3500-4000 m for 20 weeks,after which the microbiomes of both groups were analysed using high-throughput 16s rRNA sequencing and core changes in the duodenal,jejunal,ileal and colonic microflora communities were determined.Results The microbial abundance of the colon was significantly reduced in the hypoxic environment of high altitude,the microbial abundance and diversity of the foregut did not change significantly,and the AVD value of the colon was higher than that of the other intestinal segments,and it tended to be more stable after prolonged exposure to treatment in high altitude;At the Bray-curtis distance,the Microbial structure of the ileum and colon was significantly different between the Control and HA groups,whereas the duodenum and jejunum showed no significant changes;The predominant phylum in all intestinal segments was Firmicutes,but the dominant phyla varied in different intestinal segments and treatment groups,with Lactobacillus spp.contributing highly to the changes in the gut microflora;the complexity of the phylogenetic network of the ileum was higher than that of the other intestinal segments,whereas the colon had the fewest phylogenetic interactions;the jejunum and the ileum consisted mainly of abundant taxa,whereas the colon had a significantly smaller proportion of abundant taxa,mainly Conditionally rare taxa.The duodenum differed in taxa composition between the Control and HA groups.Conclusion High-altitude hypoxia can affect the microecological environment of the ileum and colon by remodelling the composition and structure of the intestinal microflora,especially in the ileum compared with the other three intestinal segments.In addition,the ileum is characterised by both lower complexity of the microflora structure and the prominent role of key genera in the high altitude hypoxia study,in which the changes of Lactobacillus spp.are worthy of more in-depth study at a later stage.Therefore,the ileal microbiota of rats may have a higher research value compared with other intestinal segments.

Irreducible anteromedial radial head dislocation (IARHD) caused by transposed biceps tendon is rare. Delayed diagnosis and surgical failure often occur. A 46-year-old fisherman presented with 10 days history of painful swelling and restricted movement of his right elbow due to strangulation injury by a fishing boat cable. On examination, the images of the right elbow reveals in a "semi-extended and pronated" elastic fixation position. Radiography and 3-dimensional reconstruction CT reveals an isolated anteromedial radial head dislocation with extreme protonation of the radius and the bicipital tuberosity towards the posterior aspect of the elbow joint, and MRI shows biceps tendon wrapping around the radial neck, similar to umbilical cord wrapping seen in newborns. The Henry approach was applied for the first time to reduce the biceps tendon. The patient achieved a good functional recovery at 26 months, which represents the first reported case of IARHD without fracture caused by biceps tendon in an adult. In treatment of IARHD, attention should be paid to the phenomenon of biceps tendon transposition. Careful clinical examination, comprehensive imaging modalities, and appropriate surgical approach are the keys to successful management.

objective To compare the surgical effect of short median incision approach and mini-incision approach in patients with medial unicompartmental knee arthroplasty.Methods A total of 65 patients with knee medial compartment osteoarthritis were treated with Oxford third-generation artificial unicondylar joint from April 2012 to July 2016 in PLA 960 hospital were enrolled.Among them,31 patients were treated with mini-incision approach and 34 patients were treated with short median incision approach.The postoperative incision healing and follow-up status of patients in the two groups were compared.The operating time of two incision approaches was counted,and the total blood loss during and after operation were calculated by Gross equation.The time to get out of bed after operation,the visual analogue scale(VAS)scores before operation,1 day after operation,1 week after operation and 1 month after operation,and the hospital for special surgery(HSS)scores before operation,1 month after operation,3 months after operation and at the last follow-up were counted.Results Three patients with previous diabetes had delayed incision healing after surgery,one patient in the mini-incision group suffered pad dislocation 6 months after operation,and three patients died of other medical diseases within 3 years after operation.The 5-year survival rate of the prosthesis was 93.85%.In the mini-incision group,the average preoperative muscle strength of quadriceps femoris was(3.10±0.60)level,and the average postoperative time to get out of bed was(1.32±0.35)days;In the short median incision group,the average preoperative muscle strength of quadriceps femoris was(3.18±0.63)level,and the average postoperative time to get out of bed was(1.37±0.41)days.There was no statistically significant difference in the postoperative time to get out of bed,operation time,total blood loss during and after operation,VAS score,HSS score of patients between the two groups(P>0.05).Conclusion The short median incision approach and mini-incision approach for unicompartmental knee arthroplasty have similar clinical effects.The short median incision approach has clearer exposure during operation,and the patellofemoral joint can be better treated,which provides conditions for modifying the surgery;the mini-incision approach is highly accepted by patients and minimizes soft tissue damage.Both of them have their own advantages.

Objective To gain insight into the natural infection of rickettsiales in ticks from the Xinjiang Uyghur Autonomous Region(XUAR)and to develop strategies for the prevention and control of tick-borne diseases.Methods A total of 7 105 adult ticks representing 12 species in seven genera were collected via hand scratching on hosts and flag-sweeping on vegetation in XJUAR,China.These samples were submitted for screening of rickettsiales infection by amplifying the outer membrane protein(ompA)gene and 16S rRNA.Results A total of 3 650 ticks were subjected to molecular analysis,with eight rickettsiae species identified as agents of the spotted fever group(SFG).Candidatus Rickettsia barbariae was initially discovered in Rhipicephalus,Hyalomma,and Haemaphysalis ticks and subsequently distributed across Hoxud,Yuli,Manas,and Huocheng cities.Furthermore,seven additional pathogenic rickettsiae species were identified,including R.conorii,R.massiliae,R.raoultii,R.slovaca,R.sibirica mongolotimonae and Candidatus Rickettsia tarasevichiae.Conclusion The presence of multiple-spotted fever group rickettsia species and the diseases they cause may represent a potential threat to human health at XJUA in China.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.
