Objective To evaluate the safety and feasibility of remote robot-assisted thoracoscopic surgery utilizing 5G technology. Methods Clinical data from five patients who underwent 5G remote robot-assisted thoracoscopic surgery at the Thoracic Surgery Center of Gansu Provincial People's Hospital from May to October 2024 were retrospectively analyzed. Results Finally, five patients were included. There were 2 males and 3 females at median age of 50 (42-63) years. All five surgeries (including 1 patient of lobectomy, 3 patients of partial lung resection and 1 patient of mediastinal lesion resection) were successfully completed without conversion to thoracotomy, complications, or mortality. The median intraoperative signal delay across the patients was 39 (37-42) ms. The median psychological load score for the surgeons was 9 (3-13). The median operation time was 100 (80-122) minutes with a median intraoperative blood loss of 100 (30-200) mL. Catheter drainage lasted a median of 4 (3-5) days, and the median drainage volumes on the first, second, and third postoperative day were 200 (100-300) mL, 150 (60-220) mL, and 80 (30-180) mL, respectively. The median postoperative hospital stay was 4 (3-7) days, and the median pain scores on the third postoperative day were 3 (1-4), 3 (0-3), and 1 (0-3), respectively. Conclusion 5G remote robot-assisted thoracoscopic surgery is safe and effective, with good surgical experience, smooth operation and small intraoperative delay.

OBJECTIVE: To explore the effectiveness of the modified Lemaire procedure in anterior cruciate ligament reconstruction (ACLR) in patients with a highly positive pivot shift test. METHODS: The clinical data of 18 patients with anterior cruciate ligament (ACL) rupture and highly positive pivot shift test between April 2020 and September 2022 were retrospectively analyzed. There were 13 males and 5 females with an average age of 28.3 years (range, 17-41 years). Causes of injury included 11 cases of direct violence injury, including 6 cases of traffic accident injury, 4 cases of sports injury, 1 case of falling injury; 7 cases of indirect violence injury, all sports injury. All patients had complete ACL rupture, including 15 acute injuries and 3 old injuries. The preoperative pivot shift test was grade Ⅱ in 9 cases and grade Ⅲ in 9 cases. All patients were treated with ACLR combined with modified Lemaire procedure. The International Knee Documentation Committee (IKDC) score and Lysholm score were used to evaluate the effectiveness before operation and at 3, 6, 12 months after operation. KT-2000 arthrometer was used to measure the anterior stability of the knee joint, and the difference between the healthy and affected sides was recorded. Pivot shift test was used to evaluate the rotational stability of the knee joint. During the follow-up, X-ray films were taken to observe the bone tunnel and internal fixation, and MRI was used to examine the healing of ACL, anterolateral collateral ligament and fibular collateral ligament grafts. RESULTS: All patients completed the operation successfully without complications such as knee joint infection, vascular and nerve injury. All patients were followed up 12-19 months (mean, 13.2 months). After operation, the rotational stability of the knee joint recovered satisfactorily, and there was no adverse symptom such as knee instability and locking at last follow-up. X-ray film and MRI showed that the bone tunnel was anatomically located and healed well, the internal fixation was in good position, and the reconstructed ACL and iliotibial band were continuous and in good tension. The IKDC score, Lysholm score, and the difference of KT-2000 between the healthy and the affected sides significantly improved at 3, 6, and 12 months after operation ( P<0.05). All the indicators further improved with time after operation, except that there was no significant difference in IKDC score between 3 and 6 months after operation and in the difference of KT-2000 between 3 months and 6, 12 months after operation ( P>0.05), and there were significant differences in other indicators between different time points ( P<0.05). Pivot shift test was negative immediately after operation and at last follow-up. CONCLUSION In ACL injuries with a highly positive pivot shift test, ACLR combined with the modified Lemaire procedure can effectively restore anterolateral knee stability, leading to satisfactory knee stability and function in the early postoperative period.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Sonodynamic therapy (SDT) can potentially induce immunogenic cell death in tumor cells, leading to the release of ATP, and facilitating the initiation of an immune response. Nevertheless, the enzymes CD39 and CD73 can swiftly convert ATP into immunosuppressive adenosine (ADO), resulting in an immunosuppressive tumor microenvironment (TME). This study introduced a nanomedicine (QD/POM1@NP@M) engineered to reprogram TME by modulating the CD39/CD73/ADO pathway. The nanomedicine encapsulated sonosensitizers silver sulfide quantum dots, and the CD39 inhibitor POM1, while also incorporating homologous tumor cell membranes to enhance targeting capabilities. This integrated approach, on the one hand, stimulates the release of ATP via SDT, thereby initiating the immune response. In addition, it reduced the accumulation of ADO by inhibiting CD39 activity, which ameliorated the immunosuppressive TME. Upon administration, the nanomedicine demonstrated substantial anti-tumor efficacy by facilitating the infiltration of anti-tumor immune cells, while reducing the immunosuppressive cells. This modulation effectively transformed the TME from an immunologically "cold" state to a "hot" state. Furthermore, combined with the checkpoint inhibitor α-PDL1, the nanomedicine augmented systemic anti-tumor immunity and promoted the establishment of long-term immune memory. This study provides an innovative strategy for combining non-invasive SDT and ATP-driven immunotherapy, offering new ideas for future cancer treatment.

In recent years, the spread of clubroot disease caused by Plasmodiophora brassicae infection has seriously affected the yield and quality of Brassica juncea (L.) Czern.. The cascade of mitogen-activated protein kinases (MAPKs), a highly conserved signaling pathway, plays an important role in plant responses to both biotic and abiotic stress conditions. To mine the MAPK genes related to clubroot disease resistance in B. juncea, we conducted a genome-wide analysis on this vegetable, and we analyzed the phylogenetic evolution and gene structure of the MAPK gene family in mustard. The 66 BjuMAPK genes identified by screening the whole genome sequence of B. juncea were unevenly distributed on 17 chromosomes. At the genomic scale, tandem repeats led to an increase in the number of MAPK genes in B. juncea. It was found that members of the same subfamily had similar gene structures, and there were great differences among different subfamilies. These predicted cis-acting elements were related to plant hormones, stress resistance, and plant growth and development. The expression of BjuMAPK02, BjuMAPK15, BjuMAPK17, and BjuMAPK19 were down-regulated or up-regulated in response to P. brassicae infection. The above results lay a theoretical foundation for further studying the functions of BjuMAPK genes in B. juncea in response to the biotic stress caused by clubroot disease.

Objective:To explore the efficacy of secondary targeted percutaneous vertebroplasty (PVP) for the treatment of refracture of injured vertebrae after vertebral augmentation for osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective case series study was performed on the clinical data of 25 patients with refracture of injured vertebrae after vertebral augmentation for OVCF admitted to Honghui Hospital, Xi′an Jiaotong University from January 2019 to January 2022, including 10 males and 15 females, aged 62-86 years [(73.8±5.2)years]. The fractured segments involved T 10 in 1 patient, T 11 in 2, T 12 in 10, L 1 in 10 and L 2 in 2. All the patients were treated with secondary targeted PVP. The operation time and the amount of bone cement injected were recorded. The visual analogue scale (VAS) of lower back, Oswestry disability index (ODI), vertebral body index (VBI) and kyphotic angle (KA) were compared before surgery, at 1 day, 6 months after surgery and at the last follow-up. Odom criteria were used to evaluate the efficacy of the surgical procedure at the last follow-up. The intraoperative bone cement leakage and new vertebrae fracture during follow-up were observed. Results:All the patients were followed up for 23-59 months [(36.8±7.6)months]. The operation time was 35-60 minutes [(42.6±5.2)minutes], with the amount of bone cement injected for 3-5 ml [(3.6±0.8)ml]. The VAS scores of lower back at 1 day, 6 months after surgery and at the last follow-up were 3.1(2.0, 4.0)points, 1.7(1.0, 2.0)points and 0.6(0.0, 1.0)points respectively, significantly lower than 7.6(7.0, 9.0)points before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The ODI values at 1 day, 6 months after surgery and at the last follow-up were (49.5±5.9)%, (28.5±4.6)% and (19.2±4.8)% respectively, significantly lower than (78.8±6.8)% before surgery ( P<0.01), and a statistically singnificant decrease was found over follow-up time ( P<0.01). The VBI values at 1 day, 6 months after surgery and at the last follow-up were (76.6±4.5)%, (76.3±4.0)% and (76.1±3.8)% respectively, significantly higher than (58.9±5.8)% before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). The KA values at 1 day, 6 months after surgery and at the last follow-up were (12.4±2.7)°, (12.6±2.5)° and (12.8±2.9)° respectively, significantly lower than (20.8±3.6)° before surgery ( P<0.01), while there were no significant differences among those at 1 day, 6 months after surgery and at the last follow-up ( P>0.05). According to the Odom criteria, 20 patients were rated excellent and 5 good at the last follow-up, with an excellent and good rate of 100%. Intraoperative asymptomatic bone cement leakage occurred in 3 patients (12%), including 2 with intervertebral leakage and 1 with lateral vertebral leakage. No adjacent vertebral body or other vertebral fracture was observed during the follow-up. Conclusions:For patients with refracture of injured vertebrae after vertebral augmentation for OVCF, the secondary targeted PVP has advantages of attenuation of the lower back pain, improvement of the quality of life, restoration of the height of refractured vertebrae, correction of the local kyphosis, and a low incidence of complications.

The clinical data, laboratory test, and gene mutations were collected from a family with pseudohypoaldosteronism type II(PHA2). The proband, aged 1 year and 7 months, presented with hyperkalemia(6.69 mmol/L; reference range 3.5-5.3 mmol/L), blood pressure of 110/68 mmHg(normal<106/61 mmHg, 1 mmHg=0.133 kPa), blood chloride of 111.5 mmol/L(reference 99-110 mmol/L), blood HCO 3- of 17.1 mmol/L(reference 22-29 mmol/L), estimated glomerular filtration rate of 128.5 mL·min -1·(1.73 m 2) -1[>90 mL·min -1·(1.73 m 2) -1], and blood renin concentration of 0.30 μIU/mL(reference 4.2-45.6 μIU/mL). The mother and maternal grandfather also exhibited normal renal function with hyperkalemia, hypertension, hyperchloremia, metabolic acidosis, and low renin. Genetic testing revealed a heterozygous missense mutation(c.1685A>G, p. E562G) in exon 7 of the no-lysine kinase 4(WNK4) gene. Treatment with hydrochlorothiazide was effective. Literature review comparing this E562G pedigree with other WNK4 variants suggested clinical heterogeneity of WNK4 mutations. For unexplained hyperkalemia, especially with concurrent hypertension, PHA2 should be considered early for genetic screening to prevent misdiagnosis or delayed diagnosis.

Objective To investigate the efficacy and safety of hybrid surgery for the recanalization of carotid artery occlusion after stenting.Methods Clinical data and results of 17 patients with occlusion after carotid artery stenting and treated with hybrid surgery from June 2016 to April 2023 at the Department of Neurosurgery Cerebral Blood Flow Reconstruction Center of Xuanwu Hospital,Capital Medical University were retrospectively analyzed.According to whether the recanalization was successful,17 patients were divided into the the successful recanalization group and the failed recanalization group.Successful recanalization was defined as achieving modified thrombolysis in cerebral infarction(mTICI)grade ≥2b and residual stenosis＜50％.Baseline data(age,sex,body mass index,smoking history,alcohol consumption history,hypertension history,diabetes history,hyperlipidemia history,coronary heart disease history),clinical data(National Institutes of Health Stroke Scale[NIHSS]score at admission,fasting blood glucose,low density lipoprotein,high density lipoprotein,total cholesterol,triglyceride,occlusion side and segment,combination with severe stenosis or occlusion of the contralateral carotid artery,opening of the anterior communicating artery,opening of the posterior communicating artery,compensation of the external and internal carotid artery,compensation of the pia artery,stump morphology,and time from imaging diagnosis of occlusion to recanalization)were documented and compared between groups.The recanalization of occlusive vessels and perioperative complications were recorded.Imaging and clinical follow-up were performed 3,6 months and≥1 year after surgery.Results Among the 17 patients,the ratio of successful recanalization was 13/17.One patient had re-occlusion after operation,which was re-opened after thrombolysis,but neck hematoma with dyspnea occurred,and recovered after emergency operation.There was no postoperative stroke or death.The incidence of perioperative complications was 1/17.Compared with the successful recanalization group,the levels of high density lipoprotein and total cholesterol in the failed recanalization group were higher,and the differences between the groups were statistically significant(high density lipoprotein[1.3±0.3]mmol/L vs.[0.9±0.3]mmol/L,t=-2.139;total cholesterol:[4.2±0.8]mmol/L vs.[3.1±0.7]mmol/L,t=-2.649;both P＜0.05);There were no significant differences in other baseline data and clinical data(all P＞0.05).Imaging follow-up was completed in 9 of the 13 patients in the successful recanalization group,and the follow-up time was 3.8-36.9 months,with a median follow-up time of 22.8(12.8,34.7)months.Among them,1 patient(1/9)developed restenosis of recanalization vessels at 33.0 months after surgery and underwent stent implantation again.Conclusions The preliminary analysis showed that the occlusion after carotid artery stenting had better recanalization success and lower perioperative complications.In patients with chronic occlusion after carotid stenting,the application of a hybrid surgery for opening may be attempted under multimodal imaging assessment.

ObjectivesTo analyze the spatial and temporal clustering characteristics and related influencing factors of late diagnosis of HIV/AIDS in Lanzhou， to identify its high-risk areas and time trends in Lanzhou， and to provide a theoretical basis for developing targeted HIV/AIDS prevention and control strategies in Lanzhou. MethodsThe subjects of this study were adult HIV/AIDS cases reported in Lanzhou City between 2011 and 2018. Data used in the study were sourced from the Lanzhou Center for Disease Control and Prevention and the Lanzhou Statistical Yearbook. To analyze the spatial distribution characteristics and influencing factors of the relative risk （RR） of late HIV/AIDS diagnosis， Bayes spatial-temporal model was used. ResultsA total of 1984 new HIV/AIDS cases were reported in Lanzhou from 2011 to 2018， with an mean age of 37.51 years and predominantly male （91.8%）. The number of late diagnosis cases was 982， with an mean age of 39.67 years and a predominance of males （91.8%）. Late diagnosis was more common in older individuals and women with HIV/AIDS. Chengguan District （51.1%）， Anning District （50.3%） and Yuzhong County （51.9%） had an above-average proportion of late diagnosis of HIV/AIDS. The proportion of late diagnosis cases in Lanzhou showed a fluctuating upward trend from 2011 to 2018. The results of Bayes spatial-temporal model showed that the risk of late HIV/AIDS diagnosis in Lanzhou had fluctuated from 2011 to 2015， and then increased rapidly after 2015 ［RR （95% credibility interval， 95%CI） increased from 1.01 （0.84， 1.23） to 1.11 （0.77， 1.97）］； the trends of risk of late diagnosis in Honggu district and three counties were similar to the overall trend in Lanzhou city， while the risk of late diagnosis in Chengguan District and Qilihe District showed a decreasing trend. The regions with the RR for late diagnosis greater than 1 included Yongdeng County （RR=1.07， 95% CI： 0.55， 1.96）， Xigu District （RR=1.04， 95% CI： 0.67， 1.49）， Chengguan District （RR=2.41， 95% CI： 0.85， 6.16）， and Qilihe District （RR=2.03， 95% CI： 1.10， 3.27）. Besides， the heatmap analysis showed that Chengguan District and Qilihe District were the hot spots. The influencing factors analysis showed that the higher GDP per capita （RR=0.65， 95% CI： 0.35， 0.90） and the larger proportion of males with HIV/AIDS cases （RR=0.53， 95% CI： 0.19， 0.92） could lead to the lower the relative risk of late HIV/AIDS diagnosis. However， the higher the population density （RR=1.35， 95% CI： 1.01， 1.81） caused the higher the risk of late diagnosis. ConclusionOur study shows the risk of late diagnosis of HIV/AIDS in Lanzhou was on the rise， and there are significant regional differences. GDP per capita， the proportion of males in HIV/AIDS cases and population density are influencing factors in the late diagnosis of HIV/AIDS. Therefore， for regions with a high risk of late diagnosis or related risk factors， targeted HIV screening and prevention services should be given priority in order to reduce the proportion and risk of late diagnosis of HIV/AIDS.

Objective:To evaluate the guiding value of ultrasound-guided selective nerve root block in the surgical treatment of multilevel lumbar degeneration.Methods:Retrospective case-control study was used. Clinical data of 47 patients with multi-level lumbar degeneration who underwent decompression surgery in Honghui Hospital, Xi′an Jiaotong University from January 2019 to December 2021 were retrospectively analyzed. They were divided into nerve root block group ( n=22)and non-nerve root block group( n=25) according to whether ultrasound-guided selective nerve root block was performed before decompression surgery. The operation time, intraoperative blood loss, number of decompression laminae, postoperative drainage volume and length of stay of the two groups were recorded and compared. The visual analogue scale of low back pain, the visual analogue scale (VAS) of leg pain, the Japanese orthopaedic association (JOA) score and Oswestry disability index (ODI) score were all compared before surgery and during follow-up between the two groups. Measurement data with normal distribution were represented as mean±standard deviation( ± s), and the comparison between groups was conducted using the paired t-test. Chi-square test was used for counting data. Results:All 47 patients successfully completed the operation without any serious complications such as neurovascular injury. All patients were followed up for (27.6±7.5)months. In the nerve root block group, the operation time, intraoperative blood loss, number of decompression laminae, postoperative drainage volume and hospital stay were (90.5±12.6) min, (110.5±15.8) mL, 1.2±0.8, (85.6±15.8) mL, (6.2±2.8) d, respectively. In the non-root block group, they were (190.6±25.5) min, (450.5±24.8) mL, 3.8±1.6, (210.5±16.8) mL, (9.5±2.2) d, respectively. The above indexes in the nerve root closure group were less than those in the non-root closure group, and the difference was significant between the two groups ( P< 0.05). The scores of VAS of low back pain and leg pain, JOA and ODI in both groups were significantly improved after surgery and during the follow-up period when compared with those of pre-operation ( P< 0.05). The VAS scores of low back pain on the 3rd day, 6 months after operation and at the last follow-up in the nerve block group were 3.2±1.4, 1.4±0.8, 0.5±0.2, the JOA scores were 15.8±4.3, 21.3±5.6, 25.6±1.4, and the ODI scores were 50.6±10.3, 22.8±7.8, 16.8±4.2, respectively. The VAS scores of low back pain on the 3rd day, 6 months after operation and at the last follow-up in the non-nerve block group were 5.1±1.8, 3.4±1.2, 1.8±0.5, the JOA scores were 14.1±4.8, 20.5±3.2, 24.2±1.8, and the ODI scores were 60.5±9.8, 31.6±8.2 and 21.3±5.5, respectively. The difference between the two groups was statistically significant ( P<0.05). However, there was no statistical difference in the VAS scores of leg pain between the two groups after surgery and during follow-up ( P>0.05). At the last follow-up, the internal fixation position of the two groups was good, no loosening and displacement, and bone graft fusion was good. Conclusion:For patients with multi-level lumbar degeneration, ultrasound-guided selective nerve root block before surgery can identify the responsible segment, and selective decompression and fusion based on this can effectively reduce surgical trauma, while improving patients′ back and leg pain and physical function, which has important surgical guidance value.
