Objective: To analyze the school tuberculosis (TB) outbreaks and preventive treatment in Hefei from 2022 to 2024, so as to provide reference for TB prevention and control in schools. Methods: Data were collected on all school based TB outbreaks occurring during 2022-2024 in Hefei, defined as ≥2 epidemiologically linked TB cases within the same school during a single semester. Statistical analyses were performed using the Chi square test. Results: Close contacts exhibited significantly higher TB incidence (2.88%) and latent mycobacterium tuberculosis infection (LTBI) rates (13.80%) in the school TB outbreaks, compared to non close contacts (0.12% and 2.63%, respectively). Among close contacts, secondary school students showed lower TB incidence (0.48%) and LTBI prevalence (3.42%) than both primary school or younger children (0.68%, 6.95%) and college students ( 0.78% , 6.50%), with statistically significant differences ( χ 2=360.91, 6.37; 791.71, 102.03, all P <0.05). The proportion of LTBI individuals recommended for preventive therapy was higher in primary school or younger groups (98.59%) than in secondary (95.25%) or college students (86.34%) ( χ 2=25.86, P <0.01). However, among those recommended, close contacts had higher uptake (85.82%) and completion rates (87.25%) of preventive therapy than non close contacts (69.63% and 70.57%); similarly, secondary school students demonstrated higher uptake (91.21%) and completion rates (86.45%) compared to primary school or younger (88.57%, 83.87%) and college students (57.28%, 64.08%) ( χ 2=30.52, 26.72; 125.17, 38.84, all P <0.01). Subsequent TB incidence among LTBI close contacts (13.30%) and among those who did not complete preventive therapy (22.73%) were significantly higher than among non close contacts (2.80%, 2.41%), respectively ( χ 2=32.19, 13.87, both P <0.05). Conclusions In school TB outbreaks, close contacts face higher LTBI prevalence and subsequent TB risk than non close contacts. College students show notably low adherence to preventive therapy. It is necessary to take targeted measures to improve the compliance of preventive measures among students.

Portal vein thrombosis （PVT） involves the main portal vein and its tributaries， and acute PVT can cause intestinal ischemia and necrosis， while chronic PVT can cause cavernous transformation of the portal vein and portal hypertension-related complications （such as ascites and gastroesophageal variceal bleeding）. Liver cirrhosis is the main risk factor for PVT. the Classification of PVT provides a basis for clinical diagnosis. Ultrasound is the preferred method for screening， and contrast-enhanced computed tomography is the gold standard for diagnosis， while magnetic resonance imaging/magnetic resonance venography can help to identify acute or chronic thrombosis. Treatment emphasizes individualized strategies： anticoagulant therapy is the first-line therapy for acute PVT， and direct oral anticoagulants have shown great potential in clinical practice； thrombolytic therapy is appropriate for severe acute PVT， and it is needed to strictly control the risk of bleeding； transjugular intrahepatic portosystemic shunt is an important method for the diagnosis and treatment of PVT-related ascites and gastroesophageal variceal bleeding； surgical operation can be used for the treatment of patients with no response to pharmacotherapy or those with serious complications such as intestinal necrosis. Future diagnosis and treatment of PVT should be based on multidisciplinary collaboration， focusing on the optimization of individualized regimens， balancing efficacy and safety， and continuously leveraging technological advances to improve clinical practice.

Objective To explore the medication patterns of the"phlegm-stasis co-treatment"in the treatment of stroke and the regulatory mechanisms of its key components.Methods The relevant literature on the treatment of stroke with intertwined phlegm and blood stasis pattern by traditional Chinese medicine in CNKI,Wanfang Data Knowledge Service Platform and VIP was collected.Excel 2019 and SPSS Modeler 18.0 were applied to statistically analyze the nature,taste,meridian tropism and frequency of the drugs included in the prescriptions.The Apriori algorithm was used to perform association rule analysis and cluster analysis.The potential mechanism of action of the core drug pair was explored by using the network pharmacology method.Results A total of 69 prescriptions involving 161 herbs with 902 cumulative frequency uses were included.The four natures were mainly warm,neutral and cold,the five flavors were mainly bitter,sweet and pungent.and channel tropism were mainly liver meridian and spleen meridian.The analysis of association rules indicates that there was a strong correlation among chuanxiong,Taoren,Dannanxing,Dilong,Honghua,Shichangpu and Fuling.The main active components of the drug combination were quercetin,gallic acid,baicalein and hederagenin.They can regulate signaling pathways such as hypoxia-inducible factor-1,advanced glycation end product/advanced glycation end product receptor,nuclear factor κB,and mixed lineage kinase 3 by acting on genes such as STAT3,SRC,JUN,TP53,and MAPK1.Conclusion The core drugs of"phlegm-stasis co-treatment"method can act on multiple targets and pathways through components such as quercetin,gallic acid,baicalein and hederagenin,thereby exerting a therapeutic effect on stroke.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.
