ObjectiveTo observe the clinical efficacy and safety of Mailuoning compound solution in the treatment of hip joint pain via nerve blocks around the hip joint. MethodsFrom March 2015 to March 2019，a total of 136 patients with hip joint pain who met the inclusion criteria were admitted and divided into an observation group and a control group according to the random number table method. Among them，six cases fell off due to failure to complete five treatments，and finally， 130 patients entered clinical observation，with 65 cases in each group. The observation group used Mailuoning compound solution for nerve blocks around the hip joint（including obturator nerve，femoral nerve branch，superior gluteal nerve， and hip fascia）. The control used Mailuoning compound solution for a simple obturator nerve block. The differences in the visual analogue scale （VAS） and Harris score of hip joint of the two groups before and after treatment were observed. Any adverse drug reactions and adverse events during the treatment of the patients were recorded. ResultsThe VAS score of the two groups was significantly decreased after treatment （P<0.01）. The observation group had a more significant decrease compared to the control group（P<0.01）. The total Harris score of hip joint， pain degree，function score， and motion of joint of the two groups were significantly improved after treatment （P<0.01）. Compared with the control group，the improvement in the total Harris score of hip joint， pain degree，and function score was more significant in the observation group （P<0.01）. The clinical efficacy based on the Harris score of hip joint of the two groups was compared. The excellent and good rate of the observation group was 84.62% （55/65）， which was significantly better than that of the control group ［56.92% （37/65）］ （χ²=12.05，P<0.01）. The follow-up results showed that the patients who achieved excellent and good results had stable curative effects and low recurrence rates，and there was no significant difference in recurrence rate between the two groups. Case analysis showed that after treatment of femoral head necrosis，the saccular transparent shadow of the femoral head was significantly reduced，and the number of bone trabeculae increased. The low-density shadow decreased as can be seen on hip X-rays. In patients with hip osteoporosis after treatment，the number of bone trabeculae increased， and the low density shadow reduced. ConclusionThe use of Mailuoning compound solution for nerve blocks around the hip joint gives full play to the synergistic effect of Mailuoning compound solution and nerve block. It can effectively relieve hip joint pain，promote the recovery of hip joint function，reduce the disability rate，and improve the quality of life of patients. Early intervention is an important link in the treatment of hip joint pain diseases，which can effectively control the development of the patient's disease. Mailuoning compound solution is a new idea and method to treat hip joint pain through neuroregulation，which is easy to operate，with high safety and good therapeutic effect. In future studies，a larger sample size is needed，and more in-depth research should be conducted on the imaging changes and mechanisms of action for various hip joint pain diseases.

Objective To investigate the factors influencing international normalized ratio (INR)>3.0 in patients undergoing warfarin anticoagulation therapy after mechanical heart valve replacement. Methods A retrospective analysis was performed on the clinical data of patients who underwent mechanical heart valve replacement surgery and received warfarin anticoagulation therapy at West China Hospital of Sichuan University from January 1, 2011 to June 30, 2022. Based on the discharge INR values, patients were divided into two groups: an INR≤3.0 group and an INR>3.0 group. The factors associated with INR>3.0 at the time of discharge were analyzed. Results A total of 8901 patients were enrolled, including 3409 males and 5492 females, with a median age of 49.3 (43.5, 55.6) years. The gender, body mass index (BMI), New York Heart Association (NYHA) cardiac function grading, INR, glutamic oxaloacetic transaminase, and preoperative prothrombin time (PT) were statistically different between the two groups (P<0.05). Multivariate logistic regression analysis revealed that lower BMI, preoperative PT>15 s, and mitral valve replacement were independent risk factors for INR>3.0 at discharge (P<0.05). Conclusion BMI, preoperative PT, and surgical site are factors influencing INR>3.0 at discharge in patients undergoing warfarin anticoagulation therapy after mechanical heart valve replacement. Special attention should be given to patients with lower BMI, longer preoperative PT, and mitral valve replacement to avoid excessive anticoagulation therapy.

Objective To evaluate the safety and efficacy of total arterial off-pump coronary artery bypass grafting (OPCABG) using a left internal thoracic artery (LITA) combined with bilateral radial arteries (RAs). Methods We retrospectively analyzed the clinical data of patients with severe multi-vessel coronary artery disease who underwent total arterial OPCABG with a LITA and bilateral RAs at Sichuan Provincial People’s Hospital from November 2020 to April 2023. Results A total of 24 patients were included, comprising 23 males and 1 female, with a mean age of (53.63±4.33) years. The New York Heart Association (NYHA) functional class was Ⅱ to Ⅲ. The mean number of distal anastomoses was 3.17±0.38. A Y-graft was constructed in 12 patients and sequential grafting was performed in 4 patients. Concomitant procedures included coronary endarterectomy in 1 patient, intra-aortic balloon pump (IABP) implantation in 10 patients, and thymoma resection in 1 patient. The mean operative time was (308.13±30.39) min, mechanical ventilation time was (15.42±7.42) h, ICU stay was (46.08±27.32) h, and postoperative hospital stay was (11.71±1.90) d. There were no in-hospital deaths. Postoperative complications included one patient of acute renal failure and one patient of cerebral infarction. Pre-discharge color Doppler echocardiography revealed that the left ventricular end-diastolic diameter was significantly smaller than before surgery (P<0.05), while the left ventricular ejection fraction and fractional shortening were significantly higher (P<0.05). Coronary computed tomography angiography (CTA) showed that all arterial grafts were patent. During a mean follow-up of (14.58±8.75) months, no patients experienced angina recurrence or mortality. Repeat coronary CTA or angiography in 16 patients one year postoperatively confirmed that all arterial grafts remained patent. Conclusion Total arterial OPCABG using a LITA and bilateral RAs is a safe and effective treatment for patients with severe multi-vessel coronary artery disease. For high-risk patients, intraoperative IABP support is recommended.

Moringa oleifera, widely utilized in Ayurvedic medicine, is recognized for its leaves, seeds, and velamen possessing traditional effects such as vātahara(wind alleviation), sirovirecaka(brain clearing), and hridya(mental nourishment). This study aims to identify the medicinal part of ■ in the Sārasvata ghee formulation as described in the Bower Manuscript, while investigating the ameliorative effects of different medicinal parts of M. oleifera on learning and memory deficits in mice and elucidating the underlying molecular mechanisms. A total of 144 male ICR mice were randomly assigned to the following groups: control, model(scopolamine hydrobromide, Sco, 2 mg·kg~(-1)), donepezil(donepezil hydrochloride, Don, 3 mg·kg~(-1)), M. oleifera leaf low-, medium-, and high-dose groups(0.5, 1, 2 g·kg~(-1)), M. oleifera seeds low-, medium-, and high-dose groups(0.25, 0.5, 1 g·kg~(-1)), and M. oleifera velamen low-, medium-, and high-dose groups(0.31, 0.62, 1.24 g·kg~(-1)). Learning and memory abilities were assessed using the passive avoidance test and Morris water maze. Nissl and HE staining were employed to examine histopathological changes in the hippocampus. Transcriptomics and targeted metabolomics were used to screen differential genes and metabolites, with MetaboAnalyst 6.0 and O2PLS methods applied to identify key disease-related targets and pathways. RESULTS:: demonstrated that M. oleifera leaf(1 g·kg~(-1)) significantly ameliorated Sco-induced learning and memory deficits, outperforming M. oleifera seeds(0.25 g·kg~(-1)) and M. oleifera velamen(1.24 g·kg~(-1)). This was evidenced by improved behavioral performance, reversal of neuronal damage, and reduced acetylcholinesterase(AChE) activity. Multi-omics analysis revealed that M. oleifera leaf upregulated Tuba1c gene expression through the synaptic vesicle cycle, enhancing glutamate(Glu), dopamine(DA), and acetylcholine(ACh) release via Tuba1c-Glu associations for neuroprotection. M. oleifera seeds targeted the dopaminergic synapse pathway, promoting memory consolidation through Drd2-ACh associations. M. oleifera velamen was associated with the cocaine addiction pathway, modulating dopamine metabolism via Adora2a-DOPAC, with limited relevance to learning and memory. In conclusion, M. oleifera leaf exhibits superior efficacy and mechanistic advantages over M. oleifera seeds and velamen, suggesting that the ■ in the Sārasvata ghee formulation is likely M. oleifera leaf, providing scientific evidence for its identification in ancient texts.

OBJECTIVE: To investigate the accuracy and safety of pedicle screw placement using 3D-printed auxiliary guides in scoliosis correction surgery for adolescents. METHODS: A retrospective analysis was conducted on the clinical data of 51 patients who underwent posterior scoliosis correction surgery from January 2020 to March 2023. Among them, there were 35 cases of adolescent idiopathic scoliosis and 16 cases of congenital scoliosis. The patients were divided into two groups based on the auxiliary tool used:the 3D-printed auxiliary guide screw placement group (3D printing group) and the free-hand screw placement group (free-hand group, without auxiliary tools). The 3D printing group included 32 patients (12 males and 20 females) with an average age of (12.59±2.60) years;the free-hand group included 19 patients (7 males and 12 females) with an average age of (14.58±3.53) years. The two groups were compared in terms of screw placement accuracy and safety, spinal correction rate, intraoperative blood loss, number of intraoperative fluoroscopies, operation time, hospital stay, and preoperative and last follow-up scores of the Scoliosis Research Society-22 (SRS-22) questionnaire. RESULTS: A total of 707 pedicle screws were placed in the two groups, with 441 screws in the 3D printing group and 266 screws in the free-hand group. All patients in both groups successfully completed the surgery. There was a statistically significant difference in operation time between the two groups (P<0.05). The screw placement accuracy rate of the 3D printing group was 95.46% (421/441), among which the Grade A placement rate was 89.34% (394/441);the screw placement accuracy rate of the free-hand group was 86.47% (230/266), with a Grade A placement rate of 73.31% (195/266). There were statistically significant differences in the accuracy of Grade A, B, and C screw placements between the two groups (P<0.05), while no statistically significant differences were observed in intraoperative blood loss, number of fluoroscopies, correction rate, or hospital stay (P>0.05). In the SRS-22 questionnaire scores, the scores of functional status and activity ability, self-image, mental status, and pain of patients in each group at the last follow-up were significantly improved compared with those before surgery (P<0.05), but there were no statistically significant differences in all scores between the two groups (P>0.05). CONCLUSION In scoliosis correction surgery, compared with traditional free-hand screw placement, the use of 3D-printed auxiliary guides for screw placement significantly improves the accuracy and safety of screw placement and shortens the operation time.

OBJECTIVES: To investigate the potential circular RNA (circRNA)-microRNA (miRNA)-messenger RNA (mRNA) immune regulatory network in childhood allergic asthma by analyzing microarray datasets. METHODS: GEO database was used to obtain the datasets of circRNA, miRNA, and mRNA from children with allergic asthma and healthy controls. The Limma package was used to identify differentially expressed circRNA (DEcircRNA), miRNA (DEmiRNA), and mRNA (DEmRNA). ENCORI and other tools were used to predict and construct the regulatory network of endogenous RNA. The DAVID database was used to perform GO and KEGG enrichment analyses, and CIBERSORT and Pearson were used to identify genes associated with immune cell infiltration. RESULTS: A total of 130 DEcircRNAs, 40 DEmiRNAs, and 802 DEmRNAs were identified between the asthma and control groups, and a regulatory network consisting of 12 circRNAs, 7 miRNAs, and 75 mRNAs was established. The GO analysis showed that the differentially expressed genes were mainly involved in the regulation of growth and development, and the KEGG analysis showed that they were mainly involved in the mTOR signaling pathway. The CIBERSORT analysis showed that compared with the control group, the asthma group had higher percentages of CD8⁺ T cells and resting NK cells and lower percentages of resting CD4⁺ memory T cells and activated mast cells. In addition, the Pearson correlation analysis identified six key mRNAs that were positively correlated with immune cell infiltration. CONCLUSIONS The ceRNA immune regulatory network constructed in this study provides a basis for research on the mechanism of childhood allergic asthma and potential therapeutic targets.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To establish a stable,reliable,and clinically relevant porcine model of endotoxin-induced acute respiratory distress syndrome(ARDS).Methods Ten 8-month-old male Bama minipigs were deeply sedated,followed by invasive mechanical ventilation and electrocardiographic monitoring.Lipopolysaccharide(LPS)was intravenously pumped at 600 μg/(kg·h)for 3 hours,then maintained at 15 μg/(kg·h)thereafter.Dynamic monitoring was performed at five time points after LPS injection(LPS 0,1,3,5,and 8 h),including arterial blood gas analysis and chest computed tomography(CT)scans.Pathological examination of lung tissues obtained via bronchoscopic biopsy(HE staining and transmission electron microscopy)was conducted.These indicators were comprehensively used to evaluate the success of the animal model.Results At 5 hours after LPS administration,8 minipigs developed symptoms such as skin cyanosis,elevated body temperature,and respiratory distress.The oxygenation index decreased to<300 mmHg.Chest CT scans showed diffuse pulmonary infiltrates.Histopathology revealed alveolar edema and hyaline membrane formation.Transmission electron microscopy demonstrated disruption of pulmonary blood-air barrier,depletion of lamellar bodies in type Ⅱ pneumocytes,inflammatory cell infiltration,and exudation of plasma proteins and fibrin.Compared with LPS 0 h,at LPS 8 h,the oxygenation index and arterial blood pH were significantly decreased(P<0.001),while blood lactic acid and serum potassium were significantly increased(P<0.05);serum calcium and base excess were significantly decreased(P<0.05),and the lung injury score based on HE-stained lung sections was significantly increased(P<0.01).Conclusion The porcine ARDS model established by continuous LPS injection can dynamically simulate the pathophysiological characteristics and typical pathological manifestations of clinical septic ARDS,making it an effective tool to study the pathogenesis,prevention,and treatment strategies of septic ARDS.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

Objective The purpose of this study was to investigate the bacterial communities of biting midges and ticks collected from three sites in the Poyang Lake area,namely,Qunlu Practice Base,Peach Blossom Garden,and Huangtong Animal Husbandry,and whether vectors carry any bacterial pathogens that may cause diseases to humans,to provide scientific basis for prospective pathogen discovery and disease prevention and control. Methods Using a metataxonomics approach in concert with full-length 16S rRNA gene sequencing and operational phylogenetic unit(OPU)analysis,we characterized the species-level microbial community structure of two important vector species,biting midges and ticks,including 33 arthropod samples comprising 3,885 individuals,collected around Poyang Lake. Results A total of 662 OPUs were classified in biting midges,including 195 known species and 373 potentially new species,and 618 OPUs were classified in ticks,including 217 known species and 326 potentially new species.Surprisingly,OPUs with potentially pathogenicity were detected in both arthropod vectors,with 66 known species of biting midges reported to carry potential pathogens,including Asaia lannensis and Rickettsia bellii,compared to 50 in ticks,such as Acinetobacter lwoffii and Staphylococcus sciuri.We found that Proteobacteria was the most dominant group in both midges and ticks.Furthermore,the outcomes demonstrated that the microbiota of midges and ticks tend to be governed by a few highly abundant bacteria.Pantoea sp7 was predominant in biting midges,while Coxiella sp1 was enriched in ticks.Meanwhile,Coxiella spp.,which may be essential for the survival of Haemaphysalis longicornis Neumann,were detected in all tick samples.The identification of dominant species and pathogens of biting midges and ticks in this study serves to broaden our knowledge associated to microbes of arthropod vectors. Conclusion Biting midges and ticks carry large numbers of known and potentially novel bacteria,and carry a wide range of potentially pathogenic bacteria,which may pose a risk of infection to humans and animals.The microbial communities of midges and ticks tend to be dominated by a few highly abundant bacteria.
